Background:
Laparoscopic right hemicolectomy can be technically challenging in patients with increased body mass index, reportedly associated with higher surgical site infection (SSI) and incisional hernia rates. We aimed to assess the association between increased body mass index and short-term outcomes of laparoscopic right hemicolectomy.
Methods:
This retrospective cohort study included patients with colon cancer who underwent laparoscopic right hemicolectomy between 2011 and 2021. Patients were managed with a standardized care protocol that comprised preoperative, intraoperative, and postoperative measures and were divided according to body mass index-normal body mass index (18-24.9 kg/m2), overweight (25-29.9 kg/m2), and obesity (≥30 kg/m2). Body mass index groups were compared for baseline characteristics and outcomes. The main outcome measures were operative time, hospital stay, 30-day complications, reoperation, number of harvested lymph nodes, and resection status.
Results:
A total of 270 patients (50% male sex; mean age: 68.7 ± 13.5 years) were included-28.5% had normal body mass index, 47% were overweight, and 24.5% had obesity. Mean operative times in obese and overweight patients were significantly longer than patients with normal body mass index (172.1 and 168.8 versus 143.3 minutes, P = .01). Compared to normal body mass index, obesity was associated with significantly higher odds of incisional SSI (odds ratio: 9.29, P = .039). Body mass index had a significant positive correlation with operation time (r = 0.205, P = .004) and incisional SSI (r = 0.126, P = .04). Body mass index groups had similar hospital stays, 30-day complications and mortality, anastomotic leak, ileus, and reoperation.
Conclusion:
Patients with increased body mass index had longer operative times and higher SSI rates, yet similar hospital stays and comparable 30-day complication rates, mortality, and reoperation to patients with normal body mass index.
