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.     

A modified suture in the surgical treatment of middle ventral hernias

Mechanical stability of the front abdominal wall median anatomic structure tissues has been examined in 49 experiments on cadavers. It was found that aponeurotic tissue of the edges of sheaths of the rectus abdominis is the most firm one. The article analyses different types of sutures used in hernioplasty. The authors propose original method of hernioplasty using the most stable anatomic structure, formation of narrow tissue duplication with a minimal amount of suture material. This method has been used in surgical treatment of 58 patients with umbilical, postoperative and linea alba hernias. There were no recurrences for 3 years.     

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.     

Preperitoneal prosthesis implantation in surgical management of recurrent inguinal hernia. Retrospective evaluation of our results 1989-1994

Recurrent inguinal hernia represents a great problem in surgery given the frequency of this operation, with a recurrence rate of 0.5-8%. Re-recurrence after repair without implantation of a prosthesis occurs in 1-23% of cases. We analyzed our results of patients with recurrent inguinal hernia, operated according to the method of Stoppa. Between 1989 and July 1994 there were 58 operations upon 55 patients with an average age of 65 years, 79% of whom had unilateral and 21% bilateral hernias. 89% of all patients underwent surgery because of a recurrent inguinal hernia. A Marlex mesh was used in 79% of the case. All patients were followed up (mean 35 months, minimum 12 months). Early complications consisted in one hematoma (1.7%), which had to be drained, as well as one early recurrence (1.7%). No infections were observed. The overall recurrence rate was 12%. However, 60% of all recurrences occurred in the few first years after introduction of this technique at our clinic; with growing number of operations and experience with Stoppa's technique, we obtained a recurrence rate of 6-7% per year. In our opinion, supported by the results of other studies, Stoppa's technique is a successful method in the treatment of recurrent inguinal hernia.     

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.     

H mesh prosthesis in the treatment of ventral hernia

The Authors report their experience in the treatment of ventral hernias using a Marlex mesh moulded in an original way with a technique partially derived from plastic surgery. The complete mobilization of the umbilicus through a circular incision allows to fit this prosthesis symmetrically below the rectus abdominis muscles for the entire extension of the hernia.     

Sliding myofascial flap of the rectus abdominus muscles for the closure of recurrent ventral hernias

Despite a reported incidence of up to 11 percent of incisional/ventral hernias following celiotomies, there is no universally applicable preventive or reconstructive technique in practice. Among patients undergoing repair of ventral incisional herniation, the reported recurrence rates are typically in the 30- to 50-percent range. This study concentrates on the patient with a large, recurrent abdominal incisional hernia in whom conventional surgical repair has failed. We report our recent 4-year experience with the use of "components separation" of the myofascial layers of the abdominal wall for repair of these recurrent herniations. During 4-year period, 35 patients with large, recurrent ventral hernias underwent repair by the same surgeon (J. H. M.) using the method described below. Abdominal defects as large as 875 cm2 were repaired, with a median defect size of 255 cm2. The repair was based on the compound flap of the rectus muscle with its attached internal oblique-transversus abdominus muscle with advancement to the midline to recreate the linea alba. Any repairs that were attenuated were supported with either ePTFE (8.6 percent) or Vicryl mesh (34 percent). The study group consisted of 35 patients, 34 percent male and 66 percent female; mean age was 55 years. Length of follow-up ranged from 1 to 43 months, with a mean follow-up of 22 months. Overall recurrence rate for herniation was 8.5 percent (3/35). Additional complications, namely seroma, wound infection, and hematoma, occurred at rates of 2.8, 5.7, and 5.7 percent, respectively. There were no mortalities. The compound flap of the rectus and internal oblique-transversus can be advanced medially to recreate the linea alba to provide dynamic, stable support for defects as large as 875 cm2. A recurrence rate of 8.5 percent was achieved in a relatively high-risk population with acceptable morbidity and no mortalities. In our 4-year experience, the sliding rectus abdominus myofascial flap has proved to be a safe and effective tool for dealing with patients in whom conventional means of repair have failed.     

The treatment of inguinal hernias by the tension-free mesh-plug alloplastic technic]

BACKGROUND: Photorefraktive keratectomy (PRK) is the most frequent refractive surgical procedure worldwide. The central corneal thickness is reduced due to removal of the anterior stroma, including Bowman's layer, with a laser beam. This procedure results in considerable alterations of the corneal structure. What does this mean for the mechanical properties of the cornea? METHODS: Intraocular pressure was increased via a 180 degrees tilt. Before and during this procedure, corneal topography was measured by photokeratoscopy. We examined 26 patients after PRK and 25 controls who had not undergone any surgical procedure. RESULTS: The corneal center flattened by 0.038 +/- 0.05 dpt (P > 0.05) in the PRK patients and by 0.187 +/- 0.045 dpt (P < 0.05) in the control group. PRK patients within 1 year after operation showed a minimal central corneal steepening, whereas PRK patients after more than 1 year showed a reaction similar to that in normal corneas (P < 0.05). CONCLUSION: Corneal stability is altered after PRK. After 1 year corneal stability seems to normalize due to stromal remodelling.     

Musculo-aponeurotic flap in the treatment of inguinal hernias, apropos of 1,600 operations

Morbidity, absention and duration of cares are important factors for the treatment of groin hernias. Deep and tension free cure is a key element to decrease the rate of recurrence. Utilization of prosthesis cannot provide a rate of 100%. This must be taken into consideration for indications. Beside we must take into account specific risks of each technique. Hernia treatment cannot be unique. This parietal surgery must remain a technique with low morbidity. As for treatment of unilateral hernia, we have qualified a technique of hernioplastia depending upon theses criteria, by inguinal incision, without prosthesis. Our technique includes: A complete dissection of the inguinal canal. The resection of the sac of the hernia at the internal ring. A deep cure of the fascia transversalis. A systematic incision of discharge on the anterior face of the rectus sheath. This incision is extremely internal and constitutes a large musculo-aponeurotic flap of 8 to 12 cm that makes this cure tension free possible. In the term of 10 years, our recurrence rate is below 1% for type I or II hernias in Nyhus classification. Consequently we discuss the indications for prosthesis. They must be reserved for hernias with high recurrence risk, bilateral hernias of for recurrent hernias.     

The surgical treatment of hiatal hernias combined with diseases of the abdominal cavity organs

An experience with treatment of 210 patients with hiatal hernias is summarized, 162 (77.1%) of them having a concomitant pathology of the abdominal cavity. Most frequently the hiatal hernias were associated with gastroduodenal ulcers (48.6%), chronic cholecystitis (18.1%), ventral hernias (5.7%). A new method of correction of hiatal hernias is described which prevents the development of complications resulting from an extreme narrowing of the hiatus. Good long-term results were obtained in 55.9% of the patients, satisfactory--in 34.3% unsatisfactory in 9.8% of the patients, results of the isolated correction of the hiatus being worse that those obtained after the combined operations. A conclusion is made that well-grounded simultaneous operations for hiatal hernias are followed by perfect medico-social and economic effects.     

Treatment of recurrent inguinal hernia by implantation of a pre-peritoneal prosthesis. Results of a prospective study

44 patients with 47 recurrent inguinal hernias entered a prospective study. All patients were operatively managed by a standardized technique using a polypropylene (Prolene) mesh inserted through a pre-peritoneal approach. Operating in the pre-peritoneal space avoids dissection of the scared cord and the "inlay" prosthetic mesh safely creates a new "fascia transversalis" with a low rate of recurrences. All patients were personally controlled every 6 months with a follow-up time of 12 to 60 months (mean 20.2 months). The low postoperative morbidity included only one seroma, no infection and no testicular complications. We observed one recurrence occurring 6 months after surgery (2%). The described operative technique using an inlay patch is recommended as the therapy of choice in all recurrent groin hernias.     

Original procedure of functional plasty of primary inguinal hernias]

We describe a novel autoplasty method we developed for primary inguinal hernia repair and report our results in nearly 150 operations. The method is based on novel principles: priority given to an individual stato-dynamic conception of the inguinal region; effect on physiological defense mechanisms of the inguinal canal; absence of tension on the sutures by autoplastic repair.     

Laparoalloplasty by the Rives' technique for the treatment of large ventral hernias. Ten-year experience]

The problems of the surgery of bulky laparoceles began to find concrete solutions with the introduction of materials of synthesis that can be used to reinforce or to substitute the abdominal wall. Despite that, the ideal prosthesis has still not been found, the Dacron (Mersilene), the Polypropylene (Marlex, Prolene) and PTFE (Goretex) are today considered the best materials for the alloplasty. The authors describe their experience in matter of bulky laparocels treated with the technique of Rives. 49 patients have been operated, using Dacron in 44 cases and Polypropylene in 5. They had no mortality and no relapse, while the most frequent complication was 6 seromas, all resolved with conservative therapy. In their series 3 infections of the subcuticular occurred more of which required the removal of the prosthesis.     

Combined surgical treatment of malignant lung tumors

Elevated titers of antibodies against different antigens of Epstein-Barr virus (EBV) are found in some immunodeficient states, malignancies or in autoimmune disorders. We examined EBV serology in the group of 22 patients with autoimmune thyroiditis as compared with the group of 35 healthy volunteers. Titers of antibodies against viral capsid antigen (IgG-VCA) were more often found in the group of patients than in the control group (p = 0.000 35 for younger than 40 years and p = 0.00115 for older than 40 years) and the positivity of antibodies against early antigen (IgG-EA-D/DR) was also significantly more often found in the group of patients (p = 0.0031 and p = 0.0019 respectively) than in the control group.
