Trocar site incisional hernia (TSIH) is one of the most common complications of laparoscopic surgery. Using the umbilical port as a common hole for removing the gallbladder in laparoscopic cholecystectomy is more likely to lead to TSIH than other ports. Thus, extracting the gallbladder through other ports may reduce the incidence of TSIH.

To ascertain whether extraction of the gallbladder through the subxiphoid port is more beneficial for reducing umbilical incisional hernia than the umbilical port.

Material and methods
From April 2014 to March 2017, a randomized clinical trial was conducted among patients with high risk of incisional hernia and accepted for three-port laparoscopic cholecystectomy (TLC) in our department. 182 patients with indications of cholecystectomy were allocated randomly to group A (subxiphoid port) and group B (umbilical port). Data collection was carried out on operative time, postoperative pain, hospital stay, wound infection and TSIH in the early postoperative course, and at 1, 10, and 24 months after surgery.

The incidence of TSIH in group A was lower than that in group B (4.9% vs. 14.6%; odds ratio = 8.02; 95% CI: 2.15–47.6; p < 0.001). The mean operative time of group A was significantly shorter than that of group B (35 ±15.16 min vs. 42 ±14.58 min, p < 0.01). There was no significant difference in wound infection rate between group A and group B (p = 0.068). The data of hospital stay (p = 0.428) and postoperative pain (p = 0.349) of all analyzed patients were similar in the two groups.

Extraction of the gallbladder through the subxiphoid port can reduce umbilical incisional hernia in high-risk patients effectively.
