40 cases of Single-incision laparoscopic surgery to totally extraperitoneal herniorrhaphy via umbilical incision under posterior rectus abdominis sheath
Abstract Background Since 2008, the first case of Single-incision laparoscopic surgery totally extraperitoneal (SILS-TEP) was reported, there was more than 10 years history on SILS-TEP. Because of difficult to operation, SILS-TEP is popularized slowly. This study investigate the safety and feasibility of SILS-TEP under posterior rectus abdominis sheath. Methods A single 2.5cm long cured incision was made along the lower umbilical border. A 5.0cm size preperitoneal space was created by electrotome or blunt dissection under the posterior sheath and the linea alba. The silica gel sealing sleeve of Iconport single port device was crammthed under the posterior rectus abdominis sheath, then the preperitoneal space was broadened toward lower abdomen in condition of CO2 gas inflation. Conventional laparoscopic instruments were used to complete the operation according to the operation procedure of laparoscopic total extraperitoneal herniorrhaphy. Results SILS-TEP hernia repair was successfully completed in 39 patients. One need an additional ports to complete totally extraperitoneal hernioplasty. Mean operative time was 73.8 minutes (range, 45 to 130 minutes) and 55.2 minutes (range, 34 to 95 minutes) in unilateral indirect hernia and in unilateral direct or femoral hernia, respectively . Mean operative time was 92.3 minutes (range, 65 to 150 minutes) in bilateral hernia. 3 seroma and 5 chronic pain were seen during the 1-6 months follow-up periods, all were treated conservatively. No other major complications. Mean post-operative hospital stay was 2.6 days. Conclusion The operation of SILS-TEP via umbilical incision under posterior rectus abdominis sheath is safe and feasible. The Iconport single-port device has potential advantages in SILS-TEP surgery.
