Comparison of conventional anterior surgery and laparoscopic surgery for inguinal-hernia repair

BACKGROUND: Inguinal hernias can be repaired by laparoscopic techniques, which have had better results than open surgery in several small studies. METHODS: We performed a randomized, multicenter trial in which 487 patients with inguinal hernias were treated by extraperitoneal laparoscopic repair and 507 patients were treated by conventional anterior repair. We recorded information about postoperative recovery and complications and examined the patients for recurrences one and six weeks, six months, and one and two years after surgery. RESULTS: Six patients in the open-surgery group but none in the laparoscopic-surgery group had wound abscesses (P=0.03), and the patients in the laparoscopic-surgery group had a more rapid recovery (median time to the resumption of normal daily activity, 6 vs. 10 days; time to the return to work, 14 vs. 21 days; and time to the resumption of athletic activities, 24 vs. 36 days; P<0.001 for all comparisons). With a median follow-up of 607 days, 31 patients (6 percent) in the open-surgery group had recurrences, as compared with 17 patients (3 percent) in the laparoscopic-surgery group (P=0.05). All but three of the recurrences in the latter group were within one year after surgery and were caused by surgeon-related errors. In the open-surgery group, 15 patients had recurrences during the first year, and 16 during the second year. Follow-up was complete for 97 percent of the patients. CONCLUSIONS: Patients with inguinal hernias who undergo laparoscopic repair recover more rapidly and have fewer recurrences than those who undergo open surgical repair.     

Cephalosporin vs penicillin

Smaller individual series on the outcome of laparoscopic hernioplasty techniques have been reported. This study reports on the complications of 3,229 laparoscopic hernia repairs performed by the authors in 2,559 patients. The TAPP (transabdominal preperitoneal) technique was the most frequently performed: 1,944 (60%). The totally preperitoneal technique was performed 578 (18%) times. The IPOM (intraperitoneal onlay mesh) repair was performed 345 (11%) times. The plug-and-patch technique was used 286 (9%) times and simple closure of the hernia defect without mesh was used in 76 (2%) repairs. Overall, there were 336 (10%) complications: 17 (0.5%) major and 265 (8%) minor. There were 54 (1.6%) recurrences, with a mean follow-up of 22 months. The TAPP technique had 19 (1%) recurrences and 141 (7%) complications. There were four bowel obstructions in this subgroup from herniation of small bowel through the peritoneal closure and trocar sites. The totally preperitoneal technique had no recurrence and 60 (10%) complications. The IPOM group had 7 (2%) recurrences and 47 (14%) complications. The plug-and-patch technique had 26 (9%) recurrences and 24 (8%) complications. The simple closure of the internal ring had 2 (3%) recurrences and 10 (13%) complications. Laparoscopic hernioplasty is not without complications. Laparoscopic hernioplasty is not without complications. Training, experience, and attention to technique will prevent some of these complications.     

Laparoscopic surgery of recurrent hernias after prosthesis (35 cases)

We report 35 cases of laparoscopic repair after prosthesis surgery using the classic open technique (19 cases) or laparoscopic technique (16 cases). Most difficulties were observed after intraperitoneal laparoscopy. Hernia repair was preferentially intrapreperitoneal (31 cases). Post-operative morbidity was low with two cases of serohematic effusion treated by puncture. Mean hospital stay was 2.5 days. Patients returned to normal activity within 7 days but work stoppage in active patients depended more on patient motivation than the initial surgical procedure. There were no reiterative recurrences although follow-up is too short (mean 21.2 months) for definitive results.     

Randomised controlled trial of laparoscopic versus open mesh repair for inguinal hernia: outcome and cost

OBJECTIVE: To compare tension-free open mesh hernioplasty under local anaesthetic with transabdominal preperitoneal laparoscopic hernia repair under general anaesthetic. DESIGN: A randomised controlled trial of 403 patients with inguinal hernias. SETTING: Two acute general hospitals in London between May 1995 and December 1996. SUBJECTS: 400 patients with a diagnosis of groin hernia, 200 in each group. Main outcome measures: Time until discharge, postoperative pain, and complications; patients' perceived health (SF-36), duration of convalescence, and patients' satisfaction with surgery; and health service costs. RESULTS: More patients in the open group (96%) than in the laparoscopic group (89%) were discharged on the same day as the operation (chi2 = 6.7; 1 df; P=0.01). Although pain scores were lower in the open group while the effect of the local anaesthetic persisted (proportional odds ratio at 2 hours 3.5 (2.3 to 5.1)), scores after open repair were significantly higher for each day of the first week (0.5 (0.3 to 0.7) on day 7) and during the second week (0.7 (0.5 to 0.9)). At 1 month there was a greater improvement (or less deterioration) in mean SF-36 scores over baseline in the laparoscopic group compared with the open group on seven of eight dimensions, reaching significance on five. For every activity considered the median time until return to normal was significantly shorter for the laparoscopic group. Patients randomised to laparoscopic repair were more satisfied with surgery at 1 month and 3 months after surgery. The mean cost per patient of laparoscopic repair was 335 pounds (95% confidence interval 228 pounds to 441 pounds) more than the cost of open repair. CONCLUSION: This study confirms that laparoscopic hernia repair has considerable short term clinical advantages after discharge compared with open mesh hernioplasty, although it was more expensive.     

The medical demands of the special athlete

BACKGROUND AND AIMS: Before choosing between open and laparoscopic preperitoneal tension-free repair, a study comparing their safety and short-term outcome was needed. No randomised studies comparing the two hernia repair techniques have hitherto been published. MATERIAL AND METHODS: A prospective randomised study was carried out comparing laparoscopic transabdominal preperitoneal mesh herniorrhaphy (n = 24) to open preperitoneal mesh herniorrhaphy (n = 25). RESULTS: When comparing unilateral repairs, the mean operation time was significantly (P < 0.01) shorter in the open group (55 min) than in the laparoscopic group (66 min). Pain on movement (P < 0.05) and pain on coughing (P < 0.01) receded more rapidly in the laparoscopic group. The median time before return to work or normal activity was 7 days (range 1-60) in laparoscopic and 5 days (1-30) in open repair. There were five (21%) complications associated with the laparoscopic procedure, while the open procedure resulted in two (8%) complications. After a median follow-up of 18 months the recurrence rate in the laparoscopic group was 13% and in the open group 8%. CONCLUSIONS: In this study the open method was associated with fewer complications and recurrences than the laparoscopic technique. Despite the decreased postoperative discomfort after laparoscopic repair, there was no significant difference in median time before return to work or normal activity. These results together with the higher cost of the laparoscopic procedure suggest that the open method is more suitable at least for unilateral hernias.     

Controlled multicenter trial of laparoscopic transabdominal preperitoneal hernioplasty vs Shouldice herniorrhaphy. Early results

BACKGROUND: In February 1993 a prospective randomized multicenter trial was initiated to compare laparoscopic transabdominal preperitoneal hernioplasty to Shouldice herniorrhaphy as performed by surgeons of nonspecialized clinics. METHODS: Until January 1994, 87 patients with 108 hernias took part in the trial (43 Shouldice and 44 laparoscopic repairs). RESULTS: The laparoscopic procedure took significantly longer than did the open operation but caused less pain as measured by pain analogue score and consumption of paracetamol and narcotics. The postoperative complication rate was 26% in the open and 16% in the laparoscopic group. The patients in the laparoscopic group were discharged earlier and their convalescence was shorter than after open hernia repair. There has been one early recurrence in the laparoscopic and two in the open group to date with a mean follow-up of 201 days. CONCLUSIONS: Laparoscopic hernia repair causes less pain than the conventional operation and enables the patient to return to full work and usual activities earlier. The recurrence rate will not be known for 5 years.     

Laparoscopic repair of recurrent ventral hernias

Break down after repair of recurrent ventral hernias can exceed 50 per cent. Laparoscopic techniques offer an alternative. This study evaluated the efficacy of the laparoscopic approach for recurrent ventral hernias. A retrospective review on all patients with a recurrent ventral hernia who underwent laparoscopic repair at our institution from August 1995 to June 1997 was performed. Demographic, operative, postoperative, and follow-up data were collected. Thirty-one patients underwent an attempted laparoscopic ventral hernia repair. Sixteen were for recurrent hernias; 15 were successfully repaired laparoscopically. The patients were typically obese (mean body mass index, 30 kg/m2), had an average of 2.4 previous open repairs (range, 1-7), and six patients had previously placed intra-abdominal mesh. An average of 3.5 (range, 1-16) defects were found per patient with a mean total hernia size of 130 cm2 (6-480 cm2). In all cases, expanded polytetrafluoroethylene mesh (average, 299 cm2) was secured with transabdominal sutures. Postoperatively patients required an average of 19 mg of narcotics (MSO4 equivalent). Bowel function returned in 1.7 days. Length of stay averaged 2.0 days (1-4 days). There were two complications: cellulitis, which resolved with antibiotics, and skin break-down, which required mesh removal. With follow-up averaging 18 months (7-29 months), there is one recurrence; the case in which the mesh was removed. Laparoscopic repair of recurrent ventral hernia seems promising. Decreased hospital stays, postoperative pain, wound complications, and a low rate of recurrence are benefits of this technique.     

Three thousand one hundred seventy-five primary inguinal hernia repairs: advantages of ambulatory open mesh repair using local anesthesia

BACKGROUND: Controversy exists over the relative advantages of open mesh repair compared with open stitching methods and the laparoscopic approach. STUDY DESIGN: Two thousand nine hundred six (2,906) consecutive unselected adult patients underwent 3,175 primary inguinal hernia repairs using polypropylene mesh, under local anesthesia on an ambulatory basis. The age range was 15-92 years. The study specifically investigated the postoperative course with regard to pain, complications, and time of return to work. RESULTS: There were no postoperative deaths and no cases of urinary retention. Two percent of patients developed a hematoma. The incidence of deep infection was 0.3%. No case of testicular atrophy occurred. Postoperatively 19% of patients used no analgesia at all; 60% used oral analgesics for up to 7 days. There was a gradual decrease in time of return to work over four successive 1-year periods. Manual workers returned to work in 15 days (median) in the first year, reducing to 9 days in the fourth year. The overall median time of return to work across the whole group was 9 days. There were eight recurrences with an 18-month to 5-year followup. CONCLUSIONS: Open mesh repair under local anesthesia is an effective day case technique, particularly in the elderly and medically unfit. The economic benefits are enhanced by low morbidity, early return to normal activities and low recurrence rates.     

Laparoscopic hernia repair in Leicester General Hospital: a prospective audit of 94 patients

Conventional hernia repair is effective in terms of cure but is associated with considerable postoperative pain and delay in return to normal activity. Laparoscopic repair has the potential to reduce pain and speed return to normal activity, but there have been few published reports of the outcome of this operation in the UK. We present a prospective audit of 94 patients who underwent laparoscopic repair. Of the 94 patients, 87 (92.6%) were male and 7 (7.4%) were female. Thirteen of the repairs were bilateral and 12 were recurrent. Two had to be converted to open repair. The mean operating time for unilateral repair was 56 min and for bilateral repair 98 min. Sixty-three patients (67%) were discharged within 24 h and 21 (22.4%) were discharged within 48 h. There were minor complications in 20 patients (21%), eight of whom (8.5%) developed a haematoma. The other minor complications included seromas (2), bruising at the site of the entry port (2), hyperaesthesia in the groin (2), port hernia (1), shoulder tip pain after surgery (3) and postoperative urinary retention (2). Nine (9.5%) patients claimed to have had no pain or discomfort at all; 35 (37.2%) were pain and discomfort free in 2 weeks. Thirty-two (34%) patients returned to normal activities in 2 weeks. With a median follow-up of 8 months 3 (3.2%) recurrences were noted. It is emphasised that this series represents a learning curve and that the operation is developmental. We are now restricting laparoscopic repair to recurrent and bilateral hernias where the technique offers particular advantages.     

A randomized, controlled, clinical study of laparoscopic vs open tension-free inguinal hernia repair

BACKGROUND: The aim of this prospective, randomized, controlled clinical study was to compare laparoscopic transabdominal preperitoneal (TAPP) hernia repair with a standard tension-free open mesh repair (open). METHODS: A total of 108 low-risk patients with unilateral (primary or recurrent) or bilateral hernias were randomized to TAPP (group 1 = 52 cases) or open (group 2 = 56 cases). The outcome measures included operating time, complications, postoperative pain, return to normal activity, operating theater costs, and recurrences. RESULTS: The mean operative time was longer for the TAPP than for the open group only in unilateral primary hernias. At rest, the median Visual Analog Scale (VAS) score was higher for group 1 than group 2 at 48 h postoperatively. Mild to discomforting pain in the inguinal region after 7 days, night pain after 30 days, and inguinal hardening after 3 months were more frequent in group 2 than group 1. No significant differences were observed in return to normal activities between the groups. One hernia recurrence was observed after 1 month in group 1. TAPP was significantly more expensive than open. CONCLUSIONS: TAPP was associated with less postoperative pain than open. The increase in operating theater costs, however, was dramatic and was not compensated by shorter time away from work. TAPP should not be adopted routinely unless its costs can be drastically reduced.     

Prospective randomized comparative study of laparoscopic hernioplasty and Lichtenstein tension-free hernioplasty]

To compare the laparoscopic transabdominal preperitoneal inguinal hernioplasty (TAPP) and the open Lichtenstein technique, in 1992 a prospective randomized trial was initiated. Until 1995 108 patients with 130 hernias took part in the trial: 64 TAPP (group A) and 66 Lichtenstein (group B). 22 patients had simultaneous bilateral repairs. Laparoscopic approach (group A) was able to expose otherwise-occult controlateral hernias in 3 cases and discovered a complex hernia (a hernia with more than one defect in the wall) in 2 patient in whom a direct hernia had been diagnosed before the operation. Mean operating time for monolateral operations was significantly longer in group A (p < 0.05). The corresponding figures for bilateral operations were longer in group B (p < 0.01). No intraoperative complications, conversions from TAPP to open repair, postoperative deaths. There were not less pain quicker mobility and shorter period of disability in the laparoscopic group (group A). Ten (15.6%) postoperative complications occurred in group A: local hematoma (6 cases, 9.3%), neuralgias (3 cases, 4.7%), urinary retention (1 case, 1.6%). Eight (12.1%) postoperative complications: hematomas (3 cases, 4.5%), urinary retention (3 cases, 4.5%), neuralgias (2 cases, 3%) occurred in group B. Differences were not significant. The current follow-up period is 36 months (15-54) in median. In both groups no recurrences occurred, but 3 patients in group B who were operated on for monolateral hernia (6.5%) discovered to be affected by contralateral hernia. The results of the present report suggest that TAPP does not appear to be associated with better results in terms of complications, pain or period of disability as compared to open tension free hernia repair, but the ability of the laparoscopic approach to expose otherwise-occult defects eliminated the risk of recurrences due to missed hernias.     

Cost-effective appendectomy. Open or laparoscopic? A prospective randomized study

BACKGROUND: Laparoscopic hernia repair has often been criticized for its high costs. METHODS: To compare the costs of laparoscopic and open hernia repair, 40 patients were randomized for either transabdominal laparoscopic or Lichtenstein mesh repair (under local anesthesia) in a day-case surgery unit. RESULTS: Median operative times for the laparoscopic and open groups were 62 and 65 min, respectively. Postoperative pain was comparable for the two groups. The period before return to normal life was 14 days in the laparoscopic group and 21 days in the open group. The hospital costs were 2051 FIM ($1 US = 4.6 FIM) higher in the laparoscopic group, but the total costs for employed patients (including expenses due to lost work days) were lower. CONCLUSION: Although the Lichtenstein operation is cheaper for the hospital, the total costs for working patients are lower with the laparoscopic technique, when the cost of lost work days is factored into overall expense.     

Mesh hernioplasty using a stapler

BACKGROUND: The recent development of laparoscopic hernioplasty has evoked extensive re-examination of the safety and effectiveness of using synthetic mesh materials in hernia surgery. We have investigated the efficacy of anterior stapling mesh repair in the treatment of inguinal hernia. METHODS: From July 1993 to June 1994, a modified open mesh hernioplasty using staples for anchorage has been performed in 127 patients. RESULTS: The mean age of patients was 61.4 +/- 13.0 years. Over 90% of them were operated on under local anaesthesia. The operation time ranged from 30 to 95 min with a median of 39 min. Only sixteen patients (12.6%) required postoperative parenteral analgesics and the median time for resuming daily activities was 7 days. Apart from two patients with reactionary haemorrhage, there was no other significant complication observed. Only one recurrence was encountered over the 26-month median follow-up period. CONCLUSIONS: We conclude that the modified mesh hernia repair with a stapling device is a feasible, inexpensive and safe procedure that is well tolerated under local anaesthesia by most patients.     

Curative laparoscopic surgery for early gastric cancer: five years experience

Sixty-one patients who were diagnosed with mucosal gastric cancer have been successfully treated with two laparoscopic techniques at our institute from March 1992 to March 1997. One is laparoscopic wedge resection of the stomach using a lesion-lifting method for lesions of the anterior wall, the lesser curvature, and the greater curvature of the stomach. The other is laparoscopic intragastric mucosal resection for lesions of the posterior wall of the stomach and near the cardia or the pylorus. Indications are as follows: (1) preoperatively diagnosed mucosal cancer; (2) <25 mm diameter elevated lesions; and (3) <15 mm diameter depressed lesions without ulcer formation. Patients were discharged in 4 to 8 days uneventfully. There was no major complication or mortality. The resected specimens had sufficient surgical margins horizontally (16 +/- 5 and 8 +/- 4 mm, respectively) and vertically. In one patient histologic examination revealed slight tumor infiltration into the submucosal layer with lymphatic invasion. He underwent gastrectomy with lymph node dissection 1 month after surgery. Otherwise, histologic examination revealed curative surgery. All patients in the series have survived during the 4- to 65-month follow-up period. There have been two recurrences in the series, both of which were found near the staple line 2 years after the initial surgery and were still mucosal lesions. They were successfully treated by open gastrectomy and laser irradiation. A separate early gastric cancer was found 2 years after the initial surgery in one patient, who then underwent curative open gastrectomy. In conclusion, if the patients are selected properly, these laparoscopic procedures are curative, minimally invasive treatment for early gastric cancer.     

Repair of ventral hernias with expanded polytetrafluoroethylene patch

BACKGROUND: Operations for large and recurrent abdominal hernias have a high associated recurrence rate, although it is lower when prosthetic material is used. Expanded polytetrafluoroethylene (ePTFE) seems to be the best tolerated prosthetic material in surgery. METHODS: A series of 45 ventral hernias repaired using ePTFE for closure or reinforcement of the herniorrhaphy has been evaluated prospectively. Thirty-six were midline incisional hernias and nine were transverse or pararectal ventral hernias. There were 13 recurrent ventral hernias and three defects were operated as an emergency procedure. The patch was sutured to the anterior aponeurosis with a running non-absorbable suture. Some other kind of intra-abdominal procedure was undertaken in 12 cases. RESULTS: ePTFE was well tolerated. Complications occurred in five patients. Major complications were found in three patients: cutaneous necrosis requiring a myocutaneous flap; and infection of the prosthesis (primary, and secondary to enterocutaneous fistula due to diverticulitis, both requiring removal of the patch). Mean follow-up was 39 months and hernia recurrence occurred in only one patient. CONCLUSION: This clinical experience shows that ePTFE is a very reliable prosthetic material for the repair of abdominal wall hernias.     

Laparoscopic retroperitoneal lymphadenectomy after chemotherapy for stage IIB nonseminomatous testicular carcinoma

PURPOSE: We investigated laparoscopic retroperitoneal lymphadenectomy after chemotherapy for stage IIB testicular carcinoma in terms of operative feasibility, overall morbidity and tumor control. MATERIALS AND METHODS: Between February 1995 and April 1998, 24 patients underwent laparoscopic retroperitoneal lymphadenectomy following initial chemotherapy for stage IIB (2 to 5 cm.) solitary or unilateral lymph node metastases. Mean tumor diameter was 2.4 cm. before and 1.1 cm. after chemotherapy. Laparoscopic retroperitoneal lymphadenectomy was performed in all patients, including those with complete remission. RESULTS: Laparoscopic retroperitoneal lymphadenectomy could be completed as planned in all patients and there was no need for conversion to open surgery. Operative time was 150 to 300 minutes (mean 240). Blood loss was minimal and no blood transfusions were required. The only postoperative complications were chylous ascites (5 patients) which resolved with conservative management (low fat diet) and a small asymptomatic lymphocele. Histological examination revealed necrosis in 71%, mature teratoma in 25% and active tumor in 4% of patients. Antegrade ejaculation was preserved in all patients. Mean postoperative hospital stay was 4 days, return to normal activities between 1 and 3 weeks, and time to complete recovery between 5 and 10 weeks. All patients were well without evidence of disease at a mean followup of 24.4 months. CONCLUSIONS: Laparoscopic retroperitoneal lymphadenectomy after chemotherapy proved feasible in select patients presenting with solitary or unilateral lymph node metastases and was associated with a low morbidity. Tumor control was not compromised by the laparoscopic approach.     

Results of laparoscopic Nissen fundoplication

BACKGROUND/AIMS: Laparoscopic surgery for treatment of gastroesophageal reflux disease was first described 5 years ago. The more widespread technique is the Nissen fundoplication with its different modifications. The early results suggest that this operation is equivalent in efficacy to the open antireflux operations. METHODOLOGY: Over a 5 year period, 622 patients underwent laparoscopic fundoplication for gastroesophageal reflux disease. Five hundred and fifty patients underwent Nissen fundoplication. Preoperative, operative and postoperative data were prospectively reviewed. One hundred twenty seven patients were evaluated 1 to 4 years after the operation. RESULTS: Laparoscopic Nissen fundoplication with standard gastric mobilisation and without division of the SGV was performed during the first three years of the laparoscopic approach. Since early 1994, we applied division of the SGV with complete mobilisation of the upper part of the gastric fundus in all the patients. The mean operative time was 86 minutes (range 30-180 minutes). Conversion to open surgery was necessary in 5 patients (0.9%). There was neither incidence of splenic trauma nor esophageal perforation. There was no mortality. Morbidity was 2.3%. Mean hospital stay was 3.1 days (range 1-13 days). Postoperative dysphagia was observed in all the patients and resolved after 2 to 6 weeks in all but 12 patients (2.1%) who were submitted to endoscopic dilatation with success in 9 patients. At a median follow-up period of 2 years (16-44 months), 127 consecutive patients from the initial experience (series 1991-1992) volunteerd for mid term follow-up evaluation. We obtained Visick I and II grading in 92% of the patients. Reoperation for failure has been necessary in 6 patients (1.0%). CONCLUSIONS: The long term results of laparoscopic Nissen fundoplication are not yet available. The incidence of poor long term outcome or recurrence of symptoms cannot be assessed. At present, we feel that, in experienced hands, the laparoscopic operation is as good as the open procedure if all the surgical principles of antireflux surgery are respected. One of our complications is related to the choice of the operative technique and that highlights the absolute necessity of strict preoperative assessment and selection of the patient but also selection of the type of operation, tailored to the patient.     

Simulation of HIV incidence dynamics in the Rakai population-based cohort, Uganda

BACKGROUND: Laparoscopic creation of an intestinal stoma may be preferable to open operation when intervention is required solely for faecal diversion. METHODS: Experience with laparoscopic intestinal stoma formation for faecal diversion from a single institution is presented. RESULTS: A total of 55 stomas were studied, 40 laparoscopic and 15 open. The conversion rate from laparoscopic to open operation was 5 per cent. Mean(s.e.m.) operating time was significantly reduced for laparoscopic stomas (54(4.7) versus 72(8.7) min). Time to return of bowel function was significantly reduced (1.6(0.3) versus 2.2(0.2) days). Mean(s.e.m.) hospital stay was significantly reduced in the laparoscopic group (7.4(0.5) versus 12.6(2.5) days). CONCLUSION: Morbidity and mortality appeared to be reduced in patients undergoing laparoscopic stoma formation. The technique was found to be safe, suitable for the majority of patients and to give results superior to those of open surgery.     

Interictal SPECT with Tc-99m HMPAO studies in migraine patients

BACKGROUND: Creating a defunctioning stoma for anorectal disease in patients in whom no resection or anastomosis is required appears eminently suited for laparoscopic techniques, with the intended advantages of early recovery, reduced pain, and avoidance of a laparotomy. OBJECTIVES: The study contained herein was undertaken to determine the feasibility of laparoscopic defunctioning stoma formation using a three-port technique (including one at the stoma site) and to compare initial results with a historical control group. METHODS: Duration of operation (anesthetic plus surgery), the time to tolerance of a liquid and then a solid diet, time to passage of flatus and feces, patient morphine requirements in the first 48 hours, and day of discharge were documented. RESULTS: Nineteen laparoscopic stomas were attempted (3 converted to open) and 23 open stomas were formed in the control group. The laparoscopic stoma group had lower morphine requirements (mean, 47.7 vs. 89.9 mg; P < 0.01), an earlier tolerance of both liquid (mean, 2.1 vs. 3.7 days; P < 0.01) and solid diets (mean, 3.6 vs. 5.5 days; P < 0.001), and an earlier time to passage of both flatus (mean, 2.2 vs. 3.6 days; P < 0.001) and feces (mean, 3.7 vs. 5.6 days; P < 0.001). Operating time was longer for the laparoscopic group (mean, 176 vs. 104 minutes; P < 0.001), whereas median time to discharge from hospital was shorter (median, 8 vs. 11 days; P = 0.014). Postoperative 30-day morbidity occurred in 1 of 19 laparoscopic group patients and 4 of 23 open group patients. CONCLUSIONS: In this select group of patients requiring defunctioning stoma only, laparoscopic surgery is feasible and safe and may have advantages over open procedures of less pain, earlier tolerance of diet, earlier return of bowel function, and a shorter median length of stay.     

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.
