Background: Locally advanced rectal cancer (LARC) can involve surrounding pelvic organs requiring multivisceral resection. Extended total mesorectal excision (e-TME) or multivisceral resection is a complex procedure associated with high morbidity, mortality, and R1 resection rates. However, e-TME in LARC with surrounding organ involvement is the only potential option for cure. The study aims to assess the clinical outcome of patients requiring e-TME for LARC.
Methods: The study is a retrospective review of all patients with LARC requiring multivisceral resection (2013 to 2019). The database includes clinic-demographic profile, pelvic organ involved, operative details, resection margin status, morbidity, mortality, and survival.
Results: Seven consecutive patients (9.2%) out of 76 LARC (median age 46 years; 5 females) required multivisceral resection. The organs involved were bladder (4); posterior wall of vagina (2); and uterus (1). The en bloc resection included total cystoprostatectomy - 1; partial cystectomy - 3; posterior vaginectomy - 2; and hysterectomy - 1. Additionally, four required abdominoperineal resection. All were adenocarcinoma: stage III, with R0 resection - 76%. The overall complications were seen in 60% of patients, majority being wound related. There was no operative mortality. The median survival was 32.2 months in the entire series, while one died with the disease at a 28-month follow-up.
Conclusion: e-TME with curative intent, though a complex procedure, is associated with high wound-related morbidity, R1 resection, but improved median survival benefit.
