Laparoscopic repair of incisional hernia: Outcomes of 100 consecutive cases comprising 25 wall defects larger than 15 cm.

BACKGROUND: Minimal access surgery for incisional hernia repair is still debated, especially for large and giant wall defects. This study was undertaken to analyze the results of the use of the laparoscopic technique in incisional hernias smaller and larger than 15 cm of diameter. METHOD: From 2002 to 2007 a total of 100 patients with incisional hernia were operated on by laparoscopy and were included in this study. As much as 38 patients were obese, with a body mass index (BMI) > 30 kg/m(2). The mean follow-up span was 24 months (range = 2-58). The fascial defect was recurrent in 19 patients, in 13 after previous repair with mesh and in 6 after repair without mesh. The wall defect was larger than 15 cm in 25 patients and in 6 of them it was 20 cm or larger as measured from within the peritoneal cavity. RESULTS: The mean operating time was 152 +/- 25 min (range = 45-275), and for defects larger than 15 cm it was 205 +/- 101 min (range = 85-540). Two patients with massive adhesions needed conversion to open surgery, one after an intraoperative injury of an intestinal loop. Postoperative complications occurred in 23 patients; local complications were 10. Pulmonary embolism caused death in one obese patient. Morbidity and hospital stay were similar in obese and nonobese patients and the differences were not statistically relevant (p > 0.05). The outcomes in patients with wall defects larger than 15 cm showed no significant difference with outcomes of the remaining patients with smaller defects (p > 0.05). Recurrence occurred in three cases, and in one case local infection led to removal of the mesh. CONCLUSIONS: Minimal access procedures can provide good results in the repair of incisional hernia, even when the diameter is larger than 15 cm. Obesity is not a contraindication to laparoscopic repair. Further studies are expected to confirm these promising results.

Laparoscopic repair of incisional hernias located on the abdominal borders: a retrospective critical review.

BACKGROUND: The aim of this study was to assess feasibility and results of laparoscopic approach to repair incisional hernias of the abdominal borders, the weakest points of abdominal wall. METHODS: Since 2002 through 2008 a total of 39 patients with fascial defects of the abdominal borders underwent laparoscopic repair. The defects were suprapubic (n=18), subxiphoidal (n=15), and lateral sided (n=6). The body mass index was >oe=30 Kg/m2 in 19 patients. The parietal defects was measured both externally and from within the peritoneal cavity and 56% of meshes were fixed only by tacks, especially in suprapubic site. RESULTS: The mean operating time was 161.8+/-25 minutes. There was 1 intraoperative complication, an intestinal injury repaired laparoscopically. Conversion was needed in 1 patient for massive adhesions. Postoperative early surgical complications were 7 (1 seroma). Morbidity in obese and nonobese patients showed no statistically relevant difference (P>0.05). There was no postoperative death. Mean hospital stay was 5.1+/-3 days. The mean follow-up was 37 months and recurrence was observed in 3 cases. CONCLUSIONS: The onlay laparoscopic approach for repair of incisional hernias of the abdominal borders can warrant good results. Obesity is not a contraindication to laparoscopic repair. Anyway, further experiences are necessary to confirm these results.
