Trocar Site Hernia after Use of an 8-mm Bladeless Trocar in Robotic Colorectal Surgery

ABSTRACT

Port site hernias are a rare complication after laparoscopic and robotic surgery. The current case is an 8-mm port site hernia which occurred after robot-assisted colorectal surgery. A 70-year-old female with a BMI (body mass index) of 25.7 was diagnosed as rectosigmoid colon cancer. She underwent a robot-assisted low anterior resection with double-stapled anastomosis for AJCC (American Joint Committee on Cancer) stage IIIB. After the main procedure, fascial defects in the supra-pubic and the supra-umbilical site were closed with a routine procedure (12 mm). Thirty two months after surgery, she developed an incisional hernia in the left mid abdomen (8-mm port). Recognition of the potential for a port site hernia using an 8-mm bladeless trocar port as well as a 12-mm port is essential in robotic surgery. Patients with risk factors for a port site hernia may require complete port site closure.
