Multicenter Study Comparative Study Controlled Clinical TrialTransanal Versus Laparoscopic Total Mesorectal Excision: A Comparative Prospective Clinical Trial from Two Centers.
Purpose: Laparoscopic total mesorectal excision (LapTME) faced many obstacles in obese male with narrow pelvis and bulky mesorectum with increased risk of incomplete mesorectal excision and positive circumferential resection margin (CRM) and distal resection margin (DRM). Transanal total mesorectal excision (TaTME) is reported to result in a better quality total mesorectal excision (TME) specimen, lower incidence of CRM and DRM involvement, and higher rates of sphincter preservation. To date, there is still a debate about the feasibility and efficacy of transanal versus the laparoscopic approach for TME in middle and low rectal cancer. ⋯ No significant differences were detected in CRM, DRM, peri- or postoperative complications, or conversion rates with more reported Clavien-Dindo grade III complications in the TaTME group (P = .29). Conclusions: TaTME facilitated rectal cancer surgery in obese patients and increased the chance of transanal specimen extraction with equivalent oncological outcomes to conventional LapTME. Further studies are recommended to build better evidence.
