Laparoscopy improves outcomes for pediatric splenectomy

BACKGROUND: Pediatric laparoscopic splenectomy is a relatively new surgical procedure with a limited number of reports comparing its outcomes to that of the open procedure. The authors have minimized the invasiveness of our procedure by using only three ports and have described the technique as well as compared it with the open method. METHODS: A retrospective review of seven laparoscopic splenectomies (LS) using a three port technique were compared with seven open splenectomies (OS) performed for similar indications at a single children's hospital. RESULTS: The average age in the LS group was 8.7 years compared with 8.9 years for OS, (P value not significant), and the average weights were also similar. The indications for splenectomy were hereditary spherocytosis, idiopathic thrombocytopenic purpura, sickle cell anemia, and splenic cyst. All splenectomies were performed safely with an average estimated blood loss of 41 mL for LS and 34 mL for OS (P value not significant). Operative time averaged 147 minutes for LS and 86 minutes for OS (P < .05). LS patients recovered more rapidly and were discharged home on a median of postoperative day (POD) 2 versus POD 4 for OS (P < .05). LS patients received significantly less total amount of intravenous pain medication with an average of 0.18 mg/kg of morphine sulfate versus 0.8 mg/kg for OS (P< .05). Total hospital charges were higher for LS with an average of $10,899 versus $8,275 for OS (P < .05). CONCLUSIONS: Laparoscopic splenectomy currently is a safe procedure, offering better cosmesis, much less pain, and a shorter hospital stay compared with the traditional open procedure. The more sophisticated equipment and time needed to carry out the procedure led to a modestly increased hospital cost.     

Laparoscopic splenectomy in children. Preliminary results and comparison with the open technique

To determine the safety and efficacy of laparoscopic splenectomy (LS) in children, a retrospective review of our preliminary experience using LS was compared to results in patients who previously underwent open splenectomy (OS). From July 1993 to January 1995, we performed eight LS procedures in six children with hereditary spherocytosis (HS) and two with immune thrombocytopenic purpura (ITP). Laparoscopic cholecystectomy was simultaneously done in one case with HS. There were 4 males and 4 females who ranged in age from 5 to 15 years--an average age of 8.8 years. Two cases in the early series required a counterincision because of bleeding. Eleven patients who previously underwent OS in our department were used to compare demographics, operative courses, and surgical outcomes. The ages, genders, diseases, body weights, and spleen weights were comparable between LS group and OS groups. The operative time for the LS group was statistically longer than for the OS group (226 +/- 24 min vs 101 +/- 8 min, P < 0.001). The estimated blood loss in the LS group was similar to that of the OS group (100 +/- 39 ml vs 73 +/- 11 ml. P = 0.97). There were no peri- or postoperative complications in two groups. The postoperative hospital stay of LS group was statistically shorter than that of the OS (6.8 +/- 0.6 days vs 10.4 +/- .05 days, P < 0.0001). LS provided better cosmesis and minimized trauma in children over OS. LS appears to be a safe and effective procedure in children, and is useful in the management of pediatric patients with HS or ITP.     

A new technique for laparoscopic splenectomy with massively enlarged spleens

Splenectomy is indicated in several hematological disorders and it can be particularly challenging in children with sickle cell disease, splenomegaly, and recurrent sequestration. Over the last 6 months, we have developed a new technique for laparoscopic splenectomy (LS) for hypersplenism and splenomegaly in five children with sickle cell disease. The average age of our patients was 6 years (range, 2-11), and the average weight was 18.7 kg (range, 13.2-30.1). On preoperative ultrasound, spleen size index ranged from 0.42 to 0.76. For the LS, four trochars were placed. One patient, who also underwent a laparoscopic cholecystectomy, had six trochars placed, two of which were used for both cholecystectomy and splenectomy. After laparoscopic mobilization of the spleen and hilar vascular stapling, a Steiner electromechanical morcellator was inserted through the 12-mm port to extract cores of splenic tissue until complete splenectomy was achieved. No patient required conversion to an open procedure or creation of a larger incision to remove the massively enlarged spleen. Operative time averaged 190 minutes; the combined LS and cholecystectomy took 245 minutes. Postoperative length of stay was <2 days for all patients. There were no complications, and no patient required postoperative transfusion. Based on these early findings, we conclude that intracorporeal coring of splenic tissue allows for safe and complete laparoscopic removal of very large spleens in small children. It provides expedient recovery and minimal postoperative pain and scarring. This new technique should enable surgeons to perform LS even in patients with massive splenomegaly, eliminating the need for large and cumbersome intracorporeal bags or the creation of additional incisions to remove the spleen.     

Elective laparoscopic splenectomy for hematologic disorders

Laparoscopic splenectomy has been reported to be the procedure of choice in selected patients with hematologic disorders. The purpose of this study is to review our experience with laparoscopic splenectomy in this patient population. The charts of all patients with hematologic disorders who presented for laparoscopic splenectomy over a 17-month period were reviewed. Fifteen patients, nine males and six females, aged 12 to 80 years (mean, 49 years) presented for laparoscopic splenectomy. Surgical indications included 13 cases of idiopathic thrombocytopenic purpura and one each of hemolytic anemia and Hodgkin's disease. Splenectomy was performed utilizing a four- or five-puncture laparoscopic technique. For completed laparoscopic splenectomies, the mean operative time was 129 minutes, and the mean estimated blood loss was 232 cc. Mean splenic weight was 210 g. There were no operative deaths. There was a single intraoperative complication, a 1700-cc hemorrhage, and two postoperative complications: pneumonitis and deep venous thrombosis. Overall morbidity was 20 per cent. A single patient (7%) required conversion to laparotomy for completion due to hemorrhage. For patients completed laparoscopically, the mean hospitalization was 1.5 days, and none required parenteral narcotics for pain control after the first 36 hours. Laparoscopic splenectomy for patients with hematologic disorders is a safe and technically feasible procedure. Decreased hospitalization and discomfort are the primary benefits. This technique should be added to the repertoire of surgeons treating patients with hematologic disorders.     

A case controlled comparison of open and laparoscopic splenectomy in children

BACKGROUND: This case controlled study compares the efficacy, safety, and cost of laparoscopic splenectomy (LS) and open splenectomy (OS) for hematologic disorders in children. METHODS: The records of 82 consecutive children and adolescents undergoing splenectomy for hematologic disorders between August 1994 and September 1997 were reviewed retrospectively. RESULTS: Fifty patients underwent LS by a lateral approach and 32 underwent OS through a left subcostal incision. Mean age was 7.76 years for LS and 6.9 years for OS. Patient weights were similar: (LS, mean 30.5 kg; OS, mean 27.6 kg). Hematologic indications included hereditary spherocytosis in 43 children (LS 26, OS 17), sickle cell anemia with sequestration in 13 (LS 7, OS 6), immune thrombocytopenic purpura in 14 (LS 8, OS 6), and 12 with other disorders (LS 9, OS 3). Concomitant cholecystectomy was performed in 10 of 50 LS and 6 of 32 OS cases. Accessory spleens were identified in 8 of 32 (25%) OS and 9 of 50 (18%) LS cases (P = .578). No LS procedures required conversion to OS. The mean estimated blood loss was 54.4 mL for LS and 49.0 mL for OS (P = .233). LS required a longer operative time (115 vs 83 minutes, P = .002), less need for postoperative intravenous narcotic (51% vs 100%, P < .0001), lower total narcotic doses (0.239 vs 0.480 mg/kg morphine, P = .006), shorter length of hospital stay (1.4 +/- 0.97 vs 2.5 +/- 1.43 days, P = .0001), and lower average total hospital charges ($5713 vs $6564) than OS. There were no deaths or major complications in either group. CONCLUSIONS: Laparoscopic splenectomy is a safe and effective procedure in children with hematologic disorders resulting in longer operative times, less narcotic administration, shorter length of stay, and lower total hospital charge.     

Laparoscopic splenectomy: outcome and efficacy in 103 consecutive patients

OBJECTIVE: To study the safety and efficacy of laparoscopic splenectomy (LS) in patients with predominantly benign hematologic disorders. SUMMARY BACKGROUND DATA: The technical feasibility of LS has been recently established. However, data regarding the efficacy of the procedure in a large cohort of patients are scarce. METHODS: One hundred three consecutive patients underwent LS between June 1992 and October 1997. Data were collected prospectively on all patients. RESULTS: Indications were idiopathic thrombocytopenic purpura (ITP), hereditary spherocytosis, autoimmune hemolytic anemia, thrombotic thrombocytopenic purpura, and others. Mean spleen size was 14 cm and mean weight was 263 g. Accessory spleens were found in 12 patients with ITP and in 5 patients without ITP. There were no deaths. Complications occurred in six patients, one requiring a second procedure for small bowel obstruction. Six patients received transfusions, and four procedures were converted to open splenectomy for bleeding. Mean surgical time was 161 minutes and was greater in the first 10 cases than the last 10. Mean postsurgical stay was 2.5 days. Thrombocytopenia resolved after surgery in 84% of patients with ITP, and hematocrit levels increased significantly in 70% of patients with chronic hemolytic anemias. A positive response was noted in 92% of patients with hereditary spherocytosis, without relapse for the duration of the observation. ITP relapsed in four patients during follow-up, three within 12 months. CONCLUSIONS: LS can be performed safely and effectively in a teaching institution. Rigorous technique will minimize capsular fractures, reducing the risk of splenosis. Accessory spleens can be successfully localized, thus improving response and limiting recurrence of ITP. LS should become the technique of choice for treatment of intractable benign hematologic disease.     

Posterolateral approach. An alternative strategy in laparoscopic splenectomy

Laparoscopic splenectomy (LS) is effective and technically feasible for treating various hematological diseases, especially idiopathic thrombocytopenic purpura (ITP). An anterior approach to the vascular pedicle is usually described. However, in this approach to the splenic hilum, the dissection of the splenic artery is often difficult. A total of 13 patients with ITP underwent elective laparoscopic splenectomy. We utilized a laparoscopic posterolateral approach involving dissection of the suspensory ligaments at the lower pole, then dissection and division of the posterolateral attachments, followed by the dissection and ligation of all splenic branches near the splenic parenchyma. This procedure was completed in 11 of our 13 patients and converted to open surgery in the other two patients. Mean operative time was 3 h; mean postoperative stay was 3 days. No blood transfusion was required, and no complications were noted in the postoperative period. The posterolateral approach provides better visualization and control of branches of the splenic vein and artery in the splenic hilum. It also permits visualization and control of surgical hemorrhage through the operating ports.     

The lateral approach for open splenectomy

BACKGROUND: Laparoscopic splenectomy (LS) has been used increasingly to treat children with hematologic disorders and has been reported to have advantages over open splenectomy performed through a standard vertical or subcostal incision. The authors perform open splenectomy (OS) through a lateral, muscle-splitting approach, and believe their approach is more reasonable in comparison with LS. METHODS: Thirty-nine consecutive open splenectomies performed between 1991 and 1995 were reviewed retrospectively and compared with recent reports of LS. The series included 24 boys and 15 girls with an average age of 9 years and average weight of 37.5 kg. Indications included immune thrombocytopenic purpura (n = 20), hereditary spherocytosis (n = 18), and sickle cell anemia (n = 1). The operation was performed with the child in the lateral decubitus position through a left upper abdominal muscle-splitting incision (off the 11th rib), sparing the rectus muscle. RESULTS: All 39 cases were completed without intraoperative complications with an average surgical time of 98.0 minutes (range, 30 to 302). The average surgical blood loss was 89 mL (range, 10 to 300). The children started feeding an average of 1.2 days (range, 0 to 4) postoperatively, were on a regular diet at an average of 2.0 days (range, 1 to 6) postoperatively, and had an average length of stay of 2.7 days (range, 1 to 6). There was no mortality or morbidity. CONCLUSIONS: Open lateral splenectomy is performed with shorter surgical times, less blood loss, an excellent cosmetic result, no complications, and a length of stay comparable to any of the published series on laparoscopic splenectomy in children. This approach provides a reasonable basis for comparison with laparoscopic splenectomy.     

Spontaneous regression of localized neuroblastoma detected by mass screening

PURPOSE: A retroperitoneal access is commonly used for open urological procedures. Since the introduction of the balloon dissecting technique by Gaur this anatomical route has also been used for laparoscopic surgery. We present our experience with retroperitoneoscopy in 200 cases. MATERIALS AND METHODS: From December 1992 to October 1997 a total of 200 retroperitoneoscopic procedures were performed in 197 patients 4 to 82 years old, comprising 78 nephrectomies, 50 renal cyst resections, 14 nephropexies, 11 ureterolyses, 8 retroperitoneal lymph node dissections, 8 renal biopsies, 6 adrenalectomies, 6 heminephrectomies, 6 pyeloplasties, 5 ureterolithotomies, 6 ureterocutaneostomies and 2 others. Of the patients 38 (19%) and 22 (11%) had undergone previous abdominal surgery, and kidney and ureter operations, respectively. Dissection of the retroperitoneal space was enabled by the use of a balloon catheter in 14, balloon trocar system in 93 and finger dissection technique in 93 cases. RESULTS: We classified 76 procedures (38%) as simple (renal biopsy, renal cyst resections, ureterocutaneostomy), 102 (51%) as difficult (adrenalectomy, nephrectomy, nephropexy) and 22 (11%) as very difficult (pyeloplasty, heminephrectomy, lymphadenectomy). There was a significant learning curve during the first 50 cases reflected by longer operating time, and higher complication, conversion to open surgery and open reintervention rates (14, 10 and 6%, respectively). In addition to the learning curve, mean operating time depended on the difficulty of the procedure, averaging 45 to 100 minutes for a simple, 95 to 185 for a difficult and 185 to 240 for a very difficult retroperitoneoscopy. In the last 50 cases the complication, conversion and reintervention rates (2, 4 and 2%, respectively) were acceptable for routine clinical application. CONCLUSIONS: After experience with more than 200 cases of retroperitoneoscopy the access technique has been significantly simplified. The procedure is standardized, safe and reproducible.     

bcl-2 protein is strongly expressed in post-transplant lymphoproliferative disorders

BACKGROUND: Splenic complications of sickle-cell disease (SCD) are associated with morbidity, and in some it may lead to mortality. This paper presents our experience with 43 patients with SCD who had splenectomy as part of their management. PATIENTS AND METHODS: The records of 43 patients with SCD who had splenectomy were examined for age at operation, sex, hemoglobin (Hb) electrophoresis, indication for splenectomy, pre- and postoperative medications, operative procedures, and postoperative complications. RESULTS: The indications for splenectomy were acute splenic sequestration crisis (ASSC) in 21 patients, hypersplenism in 15, and splenic abscess in 7. In 17 patients, the spleen was also found to be massively enlarged causing discomfort and intervening with everyday activity. For those with hypersplenism, there was a significant postoperative increase in total Hb (P < 0.0001), hematocrit (P < 0.0001), white blood cells (P < 0.0001), and platelet count (P < 0.0001). CONCLUSIONS: With careful perioperative management and proper follow-up, splenectomy in patients with SCD is beneficial in reducing their transfusion requirements and its attendant risks, eliminating the discomfort from mechanical pressure of the enlarged spleen, avoiding the risks of ASSC, and managing splenic abscess.     

Laparoscopic splenectomy in beta-thalassemia major patients. Advantages and disadvantages

BACKGROUND: Splenectomy is indicated in patients with thalassemia major when they develop hypersplenism with subsequent need for increased transfusions. Extreme splenomegaly is considered a restrictive factor for laparoscopic splenectomy in these patients. METHODS: Laparoscopic splenectomy was undertaken in 12 beta-thalassemia major patients with massive splenomegaly. The devascularization of the organ was performed with serial ligations of the splenic vessels starting from the lower pole of the organ. The spleen was extracted from the abdominal cavity through a 5-cm incision in the left iliac fossa, which incorporated two port sites. RESULTS: The procedure was concluded laparoscopically in 10 cases, while two patients were converted due to difficulty in controlling bleeding from branches of the splenic vein. The patients tolerated the procedure well and had a postoperative hospital stay of 3-6 days. CONCLUSIONS: From our limited initial experience it seems that laparoscopic splenectomy in the difficult setting of thalassemia major patients is feasible, but extreme care is required in order to avoid hemorrhagic complications.     

Laparoscopic splenectomy as an alternative to open surgery in the treatment of autoimmune thrombocytopenia

BACKGROUND: Several studies have shown the potential advantages laparoscopic splenectomy (LS) over open surgery. The aim of this study has been to evaluate the advantages of LS over open surgery in the treatment of autoimmune thrombocytopenia. PATIENTS AND METHODS: 54 consecutive patients splenectomized for the treatment of idiopathic thrombocytopenic purpura (ITP) or HIV-related thrombocytopenia were analyzed. Operative features (operative time, conversion to open surgery, accessory spleens), immediate (stay, analgesia and blood transfusion requirements) and late postoperative features (platelet count), as well as splenectomy-related complications in both surgical procedures were compared. RESULTS: Between February 1990 and February 1997, 54 splenctomies were performed for the treatment of autoimmune thrombocytopenia (ITP, n = 47, and HIV-related thrombocytopenia, n = 7). Eighteen were performed through an open approach, and 36 by laparoscopy. Both groups were comparable with regard to age, sex, platelet count, disease duration and body mass index. LS was completed in 34 cases (conversion to open surgery: 5.5%). The incidence of accessory spleens was 11% in the LS group and 5.5% in the open surgery group. Postoperative morbidity (16% vs 28%) and blood requirements (25% vs 33%) were lower after LS, but the differences did not reach statistical significance. Analgesia requirements (7 [SD 3] vs 11 [6]; p < 0.01) and postoperative stay (3.8 [2.6] vs 7.4 [3] days; p < 0.01) were significantly shorter after LS. Following splenectomy, the platelet counts became normal in 72% of patients submitted to LS and 78% of patients in the open surgery group. After 20 and 63 months mean follow-up, one patient in each group developed late complications. CONCLUSION: As compared to open surgery, LS offers a better immediate clinical outcome, with similar long-term results.     

Clinical experience with the video-assisted saphenectomy procedure for coronary bypass operations

BACKGROUND: Leg wound complications after saphenectomy are frequent after coronary bypass operations and have a detrimental effect on postoperative quality of life and treatment cost. To reduce morbidity, we evaluated a new technique of video-assisted vein harvest. METHODS: Between March 1996 and October 1996, 50 patients had video-assisted saphenectomy (VAS) and 40 patients had the standard open technique (control group). An additional 13 patients had both procedures (hybrid group). Level of pain, edema, and wound complications were evaluated at discharge and at 2, 4, and 6 weeks postoperatively. RESULTS: The mean operating time for VAS patients was slightly higher than for control (60.6+/-24.7 minutes versus 53.2+/-21.1 minutes; p > 0.05). The average incision length in VAS patients was 13.8+/-8.8 cm for an average of 3.3 grafts per patient. Three VAS procedures were aborted, two because of time constraints, and one because of bleeding, and a segment of vein was lost to injury. The VAS group had considerably less early postoperative pain than the control group (1.7+/-1.2 versus 4.1+/-1.4 [1 = mild, 10 = severe]; p < 0.005) and edema was similar for both groups. Patients in the hybrid group reported less pain in the VAS-operated leg. Serious wound infection occurred in 4 patients, with 2 patients in the control group requiring reoperation for drainage and flap reconstruction. CONCLUSIONS: Based on this initial experience, VAS harvesting, although initially more time consuming, is a rapidly mastered technique, results in shorter overall incision length, and is associated with considerably less postoperative pain than the standard open technique.     

Anesthesia case of the month. Dystocia, cesarean section and acupuncture resuscitation of newborn kittens

OBJECTIVE: To assess the results of laparoscopic splenectomy as a treatment for immune thrombocytopenic purpura (ITP). MATERIAL AND METHODS: We conducted a retrospective study of all patients who underwent laparoscopic splenectomy for ITP at our institution between August 1992 and May 1997. RESULTS: Of 27 patients who underwent attempted laparoscopic splenectomy for ITP at our institution during the study period, 26 had completion of the procedure without conversion to an open splenectomy. The median postoperative hospital stay was 1.5 days, and no postoperative deaths occurred. In one patient, pancreatitis developed postoperatively. In four patients, splenectomy failed--two initially and two subsequently--and reinstitution of medical therapy was necessary. The other patients have remained free of medication, and 19 patients have platelet counts greater than 100 x 10(9)/L. The 3-year actuarial success rate was 81.5%. Response to corticosteroid therapy preoperatively may be an indicator of success of splenectomy. CONCLUSION: Laparoscopic splenectomy is safe and allows prompt recovery. Long-term response rates are similar to those achieved with open splenectomy.     

Penile orthoplasty using dermal grafts in the outpatient setting

OBJECTIVES: To review and evaluate our extensive outpatient experience in the use of dermal grafts for the correction of significant residual chordee in patients requiring penile orthoplasty. METHODS: The medical records of all patients requiring surgical correction for severe penile curvature over the past 5 years were reviewed. Among these, 51 patients were identified in whom dermal grafts were used to correct severe residual chordee. Of these patients, 41 had severe hypospadias, 9 had epispadias, and 1 had urethral atresia. Graft harvest and placement technique, any resulting complications, and parental satisfaction with cosmetic and functional results were all evaluated. RESULTS: The dermal grafts were harvested from the hairless skin of the inguinal area, using one of two techniques. All were used to fill a tunical defect created by incising the tunica at the point of maximal penile curvature. No complications or postoperative hospitalizations resulted from any of the orthoplasty procedures. At a mean follow-up of 27 months, all patients had excellent cosmetic and functional results. CONCLUSIONS: In patients with significant residual chordee, a dermal graft is our preferred method of penile orthoplasty. This technique provides a straight phallus with a very minimal complication rate, it can easily and successfully be performed as an outpatient procedure, and it has assured an excellent cosmetic and functional result.     

Experiences with percutaneous endoscopic gastrostomy

Today the procedure of choice for long-term enteral tube feeding in patients with prolonged swallowing difficulties or inabilities is percutaneous endoscopic gastrostomy (PEG). The primary indications are head and neck cancers, neurologic dysphagia, cancer cachexia, and obstruction of the esophagus and pharynx with enough space for an endoscopic procedure. This technique requires no general anesthesia and is possible in patients with contraindications to surgical gastrostomy. Between September 1994 and April 1995 a total of 115 patients underwent PEG placement attempts. We employed the pull-technique with 15-Freka PEG tubes. The average procedure time, including esophagogastroduodenoscopy, was 17 minutes. In nine cases PEG insertion was impossible owing to severe obstruction of the esophagus. In 46 (40%) patients local abdominal pains started on the first or second postoperative day; 7 of these patients required surgical consultation, and no further intervention was needed. In only one patient was there a serious complication that required surgical intervention: a presumed perforation that turned out to have no correlate upon review. All patients received single-shot antibiotic prophylaxis; and only in those patients with abdominal symptoms do we recommend a prolonged antibiosis. The abdominal symptoms reported were due to a slight leak of gastric fluid causing a topical peritonitis, which required no further treatment. In our experience PEG is a useful alternative to surgical gastrostomy. The simplicity of this procedure leads to low complication rates, short hospitalization, and is possible on an outpatient basis. It is cost-efficient and has a much better psychological tolerance than nasogastric tubes.     

Laparoscopic splenectomy for idiopathic thrombocytopenic purpura. A 1-year follow-up study

BACKGROUND: Laparoscopic splenectomy is a novel approach for the treatment of idiopathic thrombocytopenic purpura (ITP) in patients requiring surgical intervention. This technique was used for treatment in 16 consecutive patients. Follow-up was initiated at a median of 13.5 months after surgery to determine whether or not laparoscopic splenectomy is a safe and successful procedure that should be used in all patients requiring splenectomy for ITP. METHODS: Sixteen patients underwent laparoscopic splenectomy for ITP between May 1994 and September 1996. They were evaluated prospectively prior to surgery, immediately following surgery, at discharge, and at 13.5 months following surgery (n = 14) to determine the short- and long-term results of the procedure. RESULTS: Mean operation time was 123.4 +/- 12.1 min, and there were no significant intra- or postoperative complications. Mean intraoperative blood loss was 437.5 +/- 73.5 ml. Autologous blood transfusion was necessary in one patient (6.3%). Mean organ weight was 202.2 +/- 47.3 g. Mean postoperative hospital stay was 4.6 +/- 0. 4 days. Before discharge, mean platelet count rose by 100.7%. At follow-up (13.5 months postoperatively), it was 77.7% above preoperative values. No additional surgery was necessary in any of the patients undergoing laparoscopic splenectomy, and hematologic success was achieved in 12 patients (85.7%). CONCLUSIONS: Our results clearly indicate that laparoscopic splenectomy is a safe and successful procedure in patients suffering from ITP. It offers the well-known advantages of minimal invasive surgery as well as the surgical effectiveness of the open approach. This surgical technique should therefore be considered in all patients requiring splenectomy for the treatment of ITP.     

A new technique of splenic preservation: extraperitoneal transposition of the traumatized spleen

The lifelong risk of overwhelming infection after splenectomy is well recognized. Although children are at greater risk, adults are clearly vulnerable. This is an incentive to safely preserve the spleen in splenic injuries. Nonoperative management and use of different surgical techniques and synthetic materials to stop bleeding have been experienced and reported. They have the major advantage of spleen mass preservation and prevention of splenectomy complications: but also some disadvantages, for instance: prolonged hospital stay and subdiaphragmatic collection or delayed spleen rupture. This has prompted us for splenic salvation without any attempt to stop bleeding by transposition of spleen into an extraperitoneal cavity created surgically. During a 4 year period (from the end of 1989 to the fall of 1993) ten trauma patients were treated with this original technique. All of these patients had a definitive indication for emergency laparotomy. The procedure was successful in all patients without any unexpected complication.     

Changing practice and costs of carotid endarterectomy in Toronto, Canada

BACKGROUND and PURPOSE: During our annual audits of carotid endarterectomy (CEA) in Toronto metropolitan hospitals, we have been aware of major changes in the practice of this operation in recent years. To evaluate the effect of changing practice on costs of carotid endarterectomy, we have therefore compared the effects of changes in length of stay, complication rates, and other variables on cost during the last 3 years for which we have complete data. METHODS: We evaluated 757 consecutive patients, of whom 600 had CEA procedures in 3 teaching hospitals, and 190 procedures in 2 community hospitals in metropolitan Toronto. We estimated costs using a specially designed computer program, Transitional System Incorporated, including surgical complications, in patients admitted between January 1994 and December 1996. RESULTS: There was a significant decrease in length of stay in both groups of hospitals, mainly due to preoperative outpatient evaluation but also due to lower complication rates, which probably reflect an increase in asymptomatic surgery in both hospital groups. Costs fell from approximately $8000 per procedure to $5000 in asymptomatic patients and from approximately $10,000 to $7000 in symptomatic patients (Can $). CONCLUSIONS: Major changes in the management of patients undergoing CEA have resulted in a significant decrease in both length of hospital stay and utilization of postoperative intensive care. At the same time, complication rates have significantly fallen, although our mortality and morbidity figures remain slightly higher than those from published multicenter trials. Future changes in surgical practice in Canada, including noninvasive carotid imaging, should produce even lower costs within the next few years.     

Laparoscopic splenectomy. How to make it easier using an innovative atraumatic suction grasper

BACKGROUND: With the evolution of laparoscopic surgery comes the need for specific instruments that apply traction to parenchymal tissue, like the spleen, without exposing the organ to the associated high risk of bleeding. To meet this need, we designed and developed a suction-cup grasper that allows easy grasping and manipulation of the spleen. Some of the difficulties usually encountered during laparoscopic splenectomy may be overcome by using this device. MATERIALS: The instrument consists of a cone-shaped, silicone rubber suction cup designed with an antislip internal surface. The cup is connected to a support arm with a flexible distal end that can be rotated. Traction is exerted with a commonly available suction system. The device is inserted through a 12-mm-diameter guide sheath. RESULTS: The two interventions performed with the atraumatic device were completed with laparoscopic technique. No complications arose during or after the operations. The average operating time was 110 min. The patients were discharged after 4 and 5 days postoperative, respectively. CONCLUSIONS: As a device specifically designed for grasping parenchymal organs, the atraumatic suction grasper affords the operator a faster and safer technique in laparoscopic splenectomy.
