Background:
This study aimed to describe the surgical procedures involved in laparoscopic rectal resection in patients with obesity and report the short-term outcomes.
Materials And Methods:
A total of 194 consecutive patients who underwent laparoscopic rectal resection in our department from 2013 to 2018 were divided into non-obese(body mass index[BMI] <25 kg/m2; n=161)and obese groups(BMI≥25 kg/m2; n=33)and subsequently analyzed.
Results:
The operative time was significantly longer in the obese group(225 vs 266 min; p=0.003)than in the non-obese group. No conversions to laparotomy occurred in either group, and no discernible differences in blood loss(1 vs 5 mL; p=0.582), number of harvested lymph nodes(20 vs 17; p=0.356), and postoperative complication rates(9.3 vs 6.1%; p=0.547)were observed.
Conclusion:
Establishing an appropriate operative field, clarifying landmarks, and standardizing the procedure are important to assure safe laparoscopic rectal resection with adequate lymph node dissection in patients with obesity.
