Objective:
To review the use of the left upper quadrant approach in benign gynecologic laparoscopic surgery over a nine-year period.
Design:
Retrospective review. Setting. University-affiliated hospital.
Population:
Women who underwent laparoscopic gynecologic surgery the upper quadrant approach between January 2002 and December 2010.
Methods:
Medical records were reviewed.
Main Outcome Measures:
Demographic data, past surgical histories, indications for surgery and the use of the left upper quadrant approach, intraoperative findings, diagnosis and any complications.
Results:
143 patients were identified, accounting for 4.9% of all gynecologic laparoscopic surgery. The indications for using the left upper quadrant approach were: previous open abdominal surgery (113, 79.0%), surgery in the second trimester of pregnancy (16, 11.1%), presence of large pelvic mass (9, 6.2%), previous transverse rectus abdominis myocutaneous flap for breast reconstruction (3, 2.0%), previous periumbilical hernia repair (1, 0.6%) and previous laparoscopic umbilical wound dehiscence (1, 0.6%). In women with previous abdominal surgery, the overall incidence of adhesions between omentum and/or bowel to the anterior abdominal wall in the umbilical region was 58.4%. Twelve (8.3%) patients required conversion to laparotomy. One patient had subcutaneous surgical emphysema over the left upper quadrant entry site.
Conclusions:
The left upper quadrant approach is an effective, safe and easy technique for peritoneal cavity access in women undergoing laparoscopic gynecologic surgery and should be considered in women with risk factors of periumbilical adhesions and in the presence of a large pelvic mass.
