Laparoscopic treatment for ventral hernia in obese patients.

Résumé fourni par la source

AIM: Obese patients generally are not considered good candidates for wall defect repair, because of associated comorbidities, increased surgical risk, and high risk of surgical site infection and recurrence. The purpose of this retrospective study was to evaluate the results of laparoscopic incisional hernia repair in a group of patients with Body Mass Index (BMI)>35 kg/m2. MATERIAL AND METHOD: From January 2016 to October 2018, 15 obese patients, including 11 females (73.3%) with a BMI > 35 kg/m2 underwent laparoscopic repair of an incisional abdominal hernia. Median BMI was 40 (SD±5). No selection related to comorbidities was performed. As primary endpoints, main postoperative general complications and hernia recurrence were taken into account. Secondary endpoints were the incidence of seroma, hematoma, wound infection and length of hospitalization. In addition, a systematic review of the literature on open and laparoscopic repair techniques was carried out. RESULTS: All patients were treated by laparoscopy and no conversions were required. No intraoperative complications were observed, and no patients underwent early re-intervention. Mortality was zero. One patient (6.6%) presented a seroma, conservatively managed, and evaluated over time without the need of re-intervention. One patient (6.6%) suffered a recurrence a year later, also treated by laparoscopy. Average hospital stay was 2.79 days (DS±0.77). CONCLUSIONS: Despite positive data and good results, laparoscopic treatment of wall defects has yet to be standardized. The feasibility of the laparoscopy for ventral hernias in patients with BMI>35 kg/m2 should be considered. The proposed technique is standardizable and easily reproducible. In terms of complications in the short term (perforations, kidney and pulmonary failure, cardiovascular events) and in the long term (relapses, wound infections, seromas) our results justify recommendation of the minimally invasive approach for almost all patients with abdominal wall defects.
