Therefore, the aim of this study was to introduce a novel sphincter\u2010preserving technique for anal duct ligation and muscle closure (ALMC) and analyse its perioperative outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>The data for patients who underwent ALMC for fistula\u2010in\u2010ano at Seoul Song Do Hospital between 2009 and 2023 were retrospectively reviewed. Patient demographics, intraoperative information and postoperative outcomes were assessed. The main outcomes were recurrence and wound healing. Recurrence was defined as the presence of a fistula tract or discharge more than 12\u2009weeks after the primary surgery after achieving complete healing. Faecal incontinence was also investigated clinically.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall, 556 patients (84.0% male; mean age 41.7\u2009\u00b1\u200912.3\u2009years) underwent ALMC. Among these, 152 (27.3%) had a history of fistula surgery and 261 (46.9%) had suprasphincteric fistulas. Fistula\u2010in\u2010ano recurred in 33 patients (5.9%), wound healing was delayed in 97 (17.4%) and faecal incontinence was observed in 12 (2.2%). The mean follow\u2010up duration was 10.0\u2009\u00b1\u200916.0\u2009months, and the average duration until recurrence was 13.8\u2009\u00b1\u200910.7\u2009months. The proportion of suprasphincteric fistulas was similar in those who experienced recurrence and those who did not (57.6% vs. 46.3%, respectively; <jats:italic>p<\/jats:italic>\u2009=\u20090.239). The proportion of suprasphincteric fistulas in the delayed wound healing group was slightly higher, although the differences were not statistically significant (56.7% vs. 44.9%, respectively; <jats:italic>p<\/jats:italic>\u2009=\u20090.054).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>ALMC appeared to be a safe and feasible option for treating anal fistulas, providing good perioperative outcomes, particularly when sphincter preservation was crucial.<\/jats:p><\/jats:sec>","DOI":"10.1111\/codi.17260","type":"journal-article","created":{"date-parts":[[2024,12,10]],"date-time":"2024-12-10T22:50:04Z","timestamp":1733871004000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Efficacy of anal duct ligation and muscle closure: A novel sphincter\u2010preserving surgical technique for fistula\u2010in\u2010ano"],"prefix":"10.1111","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4127-8821","authenticated-orcid":false,"given":"Yoon Hyung","family":"Kang","sequence":"first","affiliation":[{"name":"Department of Surgery Seoul Song Do Hospital  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6175-0732","authenticated-orcid":false,"given":"Keehoon","family":"Hyun","sequence":"additional","affiliation":[{"name":"Department of Surgery Seoul Song Do Hospital  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8579-3626","authenticated-orcid":false,"given":"Dong Ho","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Surgery Seoul Song Do Hospital  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jong\u2010Kyun","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Surgery Seoul Song Do Hospital  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Do\u2010Yeon","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Surgery Seoul Song Do Hospital  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,10]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1148\/rg.321115040"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/DCR.0000000000002473"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/JS9.0000000000000776"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10151\u2010023\u201002845\u20108"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10151\u2010019\u201002144\u20101"},{"issue":"3","key":"e_1_2_13_7_1","first-page":"581","article-title":"Total anal sphincter saving technique for fistula\u2010in\u2010ano;
