Our first 100 patients and our second 100 patients who underwent a laparoscopic repair of incisional and ventral hernias were compared and evaluated. This analysis revealed that the second group was approximately 9 years older with more comorbid medical conditions. In all, 15% were incarcerated hernias, and 21% were recurrent. Seven operations were converted to the open repair because of adhesions in five patients and either a small or large bowel injury in two patients. There were no complications related to enterotomy. Older and more infirm patients in the second group did not significantly affect outcomes. The average size of the hernia defects was 111 cm2. The average size of the prosthesis was 257.5 cm2. Larger prostheses were used in the second group. With more experience, the recurrence rates have declined from 9% to 4%. The etiology of these recurrences differed in these two groups of patients. Removal of the prosthetic due to infection was a predictable recurrence in two patients. A new hernia below the original hernia has caused us to repair the entire incision that had the initial hernia. Only one technical failure was noted, due to fracture of the suture during transfascial placement and clamping of the suture. It is not recommended to grasp any suture that remains in the patient during this hernioplasty. Recurrences were reduced because of the use of an increased overlap of the biomaterial and the use of dual methods of fixation (tacks and transfascial sutures).

Since the introduction of the end-to-end anastomosis (EEA) stapler for rectal reconstruction, we have used a modification of the conventional technique in which the lower rectal segment is closed with the linear stapler (TA-55) and the anastomosis is performed using the EEA instrument across the linear staple line (double stapling technique). Our experience with this procedure includes stapled colorectal anastomoses in 75 patients and is the basis for the report. This review presents the details and advantages of the technique and the results. Complications include two patients with anastomotic leak (2.7%), and two with stenosis that required treatment (2.7%). Protective colostomy was not done in this series. There were no deaths. Our experience and that of others suggests that this modification of the EEA technique can allow a lower anastomosis in some patients, and that it can be done with greater safety and facility.

A review of our initial 100 patients upon whom we attempted a laparoscopic repair of either a ventral and incisional hernia is presented. The average follow-up period of these individuals was 51 months. The operation was completed with the laparoscopic technique in 96 cases. The average defect size was 155 cm2 and the average prosthetic biomaterial size to repair these defects was 214.8 cm2. The major complication rate was 4.1%. The incidence of recurrence in these patients was 9.3%. In all of these cases of recurrence, the method of attachment was that of staples or spiral tacks alone. In 5 patients, it appeared that the prosthesis was too small to cover the defect adequately. We believe that this is an effective operation but one that has two technical mandates. The prosthetic biomaterial (DualMesh) must cover the fascial edges by a minimum of a three-centimeter overlap. Additionally, the attachment of the patch by staples or tacks alone is inadequate; consequently, the herniorraphy must include the use of through and through sutures to assure adequate fixation of the prosthesis.

Repair of parastomal represents a significant challenge for the hernia surgeon. Repair of these hernias is indicated because of an ill-fitting appliance, cosmetic deformity, inability to maintain proper hygiene and complications from the hernia itself such as incarceration or strangulation. Recent reports in the literature have shown that primary fascial repair can occur in 46% of patients and relocation of the stoma is associated with a 40% recurrence rate. For this reason, the use of polypropylene mesh has been applied to this repair. The recurrence rate with this open technique will still incur a failure rate of 20-29%. Additionally there are other complications such as obstruction, fistulization or mesh erosion with this biomaterial. The laparoscopic approach to this hernia may offer a new choice for this difficult problem. We have used ePTFE to repair 12 parastomal hernias with three different approaches. There have been eight colostomy, two ileostomy and two urostomy hernias. Follow-up ranges from 3-39 months (average 20 months). There has been one recurrence that required two repairs (8%). Other complications included enterotomy (one patient), ileus (one), seroma (one), and death from postoperative aspiration (one). The laparoscopic repair of parastomal hernias appears to be a promising technique for this complex dilemma.

Abnormal healing processes after implantation of polypropylene mesh may increase complications of the transabdominal preperitoneal and total extraperitoneal approaches in laparoscopic inguinal hernia repair, whereas the minimal response to ePTFE meshes may make them safer for use in the preperitoneal space.

Our results are markedly different from animal studies and show that ePTFE has minimal shrinkage after LIVH repair. The use of transfascial sutures in addition to tack fixation may have an implication on the mesh contraction rates.

There are new prosthetic biomaterials that are used to repair various defects in the abdominal wall. These have been developed within the last several years. The results of many of these products are not yet available. We report on two patients who developed chronic-pain syndromes that could only be related to the use of Composix mesh. This entity may become more conspicuous in the future, thereby presenting the surgeon with difficulty in approaching this new and difficult problem. We believe that shrinkage of the prosthesis was responsible for the pain. Both of these patients responded favorably to resection of the mesh by the open or laparoscopic technique. This was followed by repair of the fascial defect with DualMesh by the open or laparoscopic method. We were successful in the achievement of the relief of the pain and the repair of the hernia in both cases. We believe that this entity can be treated successfully by this approach. The laparoscopic method is favored.
