Laparoscopic incisional hernia repair in obese patients

Abstract

Background and objectives: Laparoscopic incisional hernia repair is coming to the forefront as a preferred method of repair due to the advantages offered by minimally invasive techniques. To evaluate safety and feasibility of this approach in obese patients when performed by a general surgeon trained in basic laparoscopy with no prior experience in this technique, we reviewed our early experience in the first 18 patients.

Methods: All patients with incisional hernias presenting to a single surgeon from 2000 to 2002 were offered laparoscopic repair. Patients were informed about the limited experience of the surgeon in this particular field. Those who consented were repaired laparoscopically using a standard 4-port technique, one 12-mm port and three 5-mm ports. All patients with body mass index > or =30 were included in this review. A retrospective review of the data included demographics, operative time, blood loss, hospital stay, postoperative complications, and patient satisfaction.

Results: Nineteen laparoscopic repairs were completed in 18 patients. No conversions to open repair were necessary. All patients were females except for 2. All hernia sacs were left in place, some of which were empty while others required extensive lysis of adhesions to release sac contents. Mean fascial defect was 102.5 cm2. One defect was closed primarily without mesh, while the rest were closed using Composix mesh in 1 and Dual Plus Gore-Tex mesh in the rest. Three patients were discharged from the recovery room. Mean follow-up was 24 months. No wound or mesh infections occurred. Eight patients had no complications. Eight patients had asymptomatic seromas. Two patients had hematomas; none of them required drainage. One patient had nonspecific dizziness. One patient presented with bowel obstruction secondary to early recurrence (within a week). The repair was salvaged laparoscopically. Upon evaluation by telephone calls, all patients indicated extreme satisfaction with the results.

Conclusions: A general surgeon with training in basic laparoscopy can safely perform laparoscopic incisional hernia repair on obese patients with minimal complications. The procedure requires a short leaning curve of no more than 3 cases and few extra materials to be feasible at any hospital in the US. Patient satisfaction with this technique is certainly gratifying.
