The protective effect of body mass index in

The incidence of trocar site herniation differs in various studies. The incidenceof these hernias is increased in patients who experience significant weight gain post-operatively. The aim of this study was to compare the complication of closed trocar portsite with open port and effect of body mass index on the herniation using trocar site incisionin laparoscopic surgery. In this prospective, randomized clinical, a total of 100 patients were scheduledto undergo appendectomy, cholecystectomy, ovarian cyst excision, herniorraphy and diagnosticlaparoscopy at the Surgical Gastroenterology Service of The Baqiyatallah Hospital.Patients were randomly distributed into group OP (open port, n= 52) and group CP (closedport, n = 48). The follow up intervals were at 3 and 12 months after surgical operation Five patients in OP group developed incision hernia. Regarding infection, hematoma,there was no significant difference between the two groups. Surprisingly, in OPgroup the average BMI (kg/m²) in herniated patients was significantly less than nonherniatedcases. An important step to avoid post laparoscopic hernias is suturing the fasciawhenever the trocar diameter exceeds 10 mm. If surgeons tend to have an open trocarsite of 10 mm, particularly in facial defects; the trocar site is protected from incision herniain obese patients with high BMI.
