Summary
Omitting splenic flexure mobilization during laparoscopic rectal surgery allows preservation of sigmoid colon and marginal artery, ensuring safe anastomosis. This approach is safe for rectal cancer patients.
Area of Science:
- Surgical Oncology
- Gastrointestinal Surgery
- Minimally Invasive Surgery
Background:
- Laparoscopic rectal surgery aims for safe anastomosis.
- Complete splenic flexure mobilization (SFM) is a standard but potentially extensive part of the procedure.
Purpose of the Study:
- To compare the surgical safety of omitting SFM during laparoscopic rectal surgery.
- To evaluate if preserving sigmoid colon and marginal artery is feasible and safe.
Main Methods:
- Prospective analysis of 160 patients undergoing laparoscopic rectal resection for rectosigmoid and rectal cancer.
- Morbidity, mortality, SFM rate, and anastomotic complications (leakage, bleeding, stricture) were recorded.
- Exclusion of 5 patients who underwent abdominoperineal resection (APR).
Main Results:
- No operative mortalities observed.
- SFM was required in only 4.5% of cases.
- Anastomotic leakage occurred in 8.4%, bleeding in 2.6%, and strictures in 1.9%.
Conclusions:
- Omission of complete SFM is safe in laparoscopic rectal surgery.
- A portion of the sigmoid colon can be safely preserved for anastomosis.
- This technique allows for safe rectal cancer resection with preserved bowel segments.
