Clinical study of 231 cases of radical excision with sphincter preservation by casing anastomosis in low rectal cancer / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical efficacy, feasibility and safety of sphincter-preserving procedure by casing anastomosis of colon and rectal mucosa in low rectal cancer.</p><p><b>METHODS</b>A retrospective analysis was carried out in 231 cases of low rectal cancer performed casing anastomosis.</p><p><b>RESULTS</b>One hundred and ninety-seven (197/231, 85.3%) cases were followed up, the median time of the follow up was 5.9 years (range, 2 months-14 years). Eight (3.4%) cases of stoma leak and 3 (1.2%) cases of stoma stenosis were found post operation. Defecating function recovered normally (1 - 3 times per day) in 12 - 24 weeks after operation in all patients. Local recurrence was found in 5.1% (10/197) of the cases. Hepatic and lung metastasis was found in 15.2% (30/197) and 2.5% (5/197) of the patients, respectively. The five-year survival rate was 71.6% totally.</p><p><b>CONCLUSIONS</b>The casing anastomosis procedure with sphincter preservation is safe and efficacy for low rectal cancer. With the procedure, the anal function can be preserved well, stoma leak is decreased, and the five-year survival rate is the same as Miles operation.</p>
