Either method can be used if the lower edge of the tumor is 4-6 cm from the anal verge. The goal of this study was to evaluate differences in the anal function after MCAA or HCAA. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; The subjects were 305 consecutive patients with primary rectal cancer tumors situated 4-6 cm from the anal verge who underwent curative anus-preserving surgery between 2004 and 2013. Functional assessment was performed using a questionnaire at 3, 6, 12, and 24 months after stoma closure. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Of the 305 patients, 145 underwent MCAA and 160 underwent HCAA. The median distance of the tumor from the anal verge was 6.0 cm (range 4.0-6.0) in the MCAA group and 4.5 cm (range 4.0-6.0) in the HCAA group (&lt;i&gt;p&lt;\/i&gt; &lt; 0.001). A total of 192 patients (73%) responded to the 1-year questionnaire. The median Wexner score was 6 (range 0-17) in the MCAA group and 11 (range 0-20) in the HCAA group (&lt;i&gt;p&lt;\/i&gt; &lt; 0.001). &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Retention of anal function is feasible after both MCAA and HCAA. MCAA may contribute to better postoperative anal function compared to HCAA.<\/jats:p>","DOI":"10.1159\/000456080","type":"journal-article","created":{"date-parts":[[2017,4,5]],"date-time":"2017-04-05T21:04:01Z","timestamp":1491426241000},"page":"469-475","source":"Crossref","is-referenced-by-count":7,"title":["Anal Function after Surgery for Low-Lying Rectal Cancer: Comparison of Mechanical and Hand-Sewn Coloanal Anastomosis"],"prefix":"10.1159","volume":"34","author":[{"given":"Rie","family":"Matsunaga","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuji","family":"Nishizawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norio","family":"Saito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitsuru","family":"Yokota","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryuichi","family":"Hayashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaaki","family":"Ito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2017,4,6]]},"container-title":["Digestive Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/456080","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/456080","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/456080","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:13:40Z","timestamp":1745428420000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000456080"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2017,10,25]]}},"URL":"https:\/\/doi.org\/10.1159\/000456080","archive":["Portico"],"relation":{},"ISSN":["0253-4886","1421-9883"],"issn-type":[{"value":"0253-4886","type":"print"},{"value":"1421-9883","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
