Intersphincteric resection for very low rectal cancer: a systematic review

摘要: Radical surgical treatment for very low rectal cancer near the anus has generally involved abdominoperineal resection. Various sphincter-saving operations have been developed such tumors to optimize patients' postoperative quality of life. Current protocols focus on intersphincteric resection (ISR), which differs from conventional hand-sewn coloanal anastomosis (CAA) after anterior However, efficacy ISR remains unclear. The surgical, oncologic, and functional outcomes (ISR) were reviewed. This review current literature was conducted by searching PubMed online database. Articles focusing specifically CAA excluded this study. mean mortality rate is <2 %, morbidity ranges 7.7 38.3 %. local recurrence varies widely 0 22.7 with a follow-up duration 40-94 months. disease-free overall 5-year survival rates are 69-86 79-97 months, respectively.
