“…On the one hand, five studies [22,24,[26][27][28] indicated that a bulky tumor was not suitable for NOSE in colorectal cancer and that transvaginal access [22,24,27] was not recommended for patients with vaginal narrowing, pelvic surgery, or endometriosis. On the other hand, evidences have indicated that patients with a higher body mass index (BMI) have an increased prevalence of incisional hernia after laparoscopic colorectal surgery [40]. In addition, Senagnore et al [41] showed that patients with a higher BMI were associated with a higher conversion rate to open surgery, longer operation time, higher prevalence of complications, and higher prevalence of anastomotic leakage in laparoscopic colectomy.…”
