Application of laparoscopic transanal coloanal anastomosis in sphincter-preserving surgery for low rectal cancer / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy of laparoscopic transanal coloanal anastomosis (modified Parks procedure) in sphincter-preserving surgery for low rectal carcinoma.</p><p><b>METHODS</b>Clinical data of 65 low rectal cancer patients undergoing laparoscopic modified Parks procedure from March 2009 to April 2012 in our department were reviewed retrospectively. Fecal continence, urination and sexual function were evaluated.</p><p><b>RESULTS</b>All the patients were followed up from 6 to 38 months after operation. Anastomotic leakage was found in 2 cases, anastomotic stricture in 3 cases, hepatic metastasis in 1 case. No local recurrence occurred. The ratio of satisfactory defecation function was 61.5% (40/65) in six months, 84.2% (48/57) in 1 year and 88.9% (40/45) in 2 years respectively. Urinary dysfunction was found in 7 patients (10.8%). Among 36 male patients, 7 (19.4%) presented erectile dysfunction and 10 (27.8%) ejaculation dysfunction. Among 29 female patients, sexual life of 19 (65.5%) was satisfactory.</p><p><b>CONCLUSION</b>Laparoscopic modified Parks procedure in sphincter-preserving surgery for low rectal cancer can increase the ratio of sphincter-preserving, and improve the functional outcomes of defecation, sex and urination.</p>
