Recently, the use of radiofrequency for hemorrhoidectomy has minimized incidence of postoperative complications. Effectiveness of LigaSure is demonstrated, but it is quite expensive. This study aims to compare LigaSure with Caiman, a cheaper instrument that uses radiofrequency for hemorrhoidectomy. Methods. A total of 35 patients were enrolled in this study between January 2015 and December 2017: 35 (Group A: Caiman) patients were matched with 35 control patients (Group B) from our historical cohort, treated with LigaSure. They were checked at 1 week after operation, at 4 weeks, and then after 2, 6, and 12 months. We considered different factors: intraoperative (operative time, number of piles removed, necessity of stiches or ligation), immediate postoperative (pain, bleeding within 4 weeks, incontinence, soiling within 4 weeks, healing time of anal wounds, return to working activities), and with a long-term follow-up. Results. There were no statistically significant differences between the 2 groups in analyzed intraoperative data: operative time (Group A 35 minutes vs Group B 33 minutes; P = .198) and stitches used. Postoperative data were comparable too, in particular pain (Group A 1 day Visual Analog Score = 6.25 vs Group B = 5.4, P = .178; Group A 1 week Visual Analog Score = 2.7 vs Group B = 1.14, P = .22) and bleeding (Group A = 2 vs Group B = 4; P = .2). Conclusions. According our initial experience, Caiman can be a safe and cheaper alternative to LigaSure for hemorrhoidectomy.<\/jats:p>","DOI":"10.1177\/1553350620908388","type":"journal-article","created":{"date-parts":[[2020,3,5]],"date-time":"2020-03-05T05:55:15Z","timestamp":1583387715000},"page":"272-278","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Caiman Versus LigaSure Hemorrhoidectomy: Postoperative Pain, Early Complications, Long-Term Follow-up, and Costs"],"prefix":"10.1177","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7973-6990","authenticated-orcid":false,"given":"Chiara","family":"Eberspacher","sequence":"first","affiliation":[{"name":"Sapienza University of Rome, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pietro","family":"Mascagni","sequence":"additional","affiliation":[{"name":"IHU Strasbourg\u2014Institute of Image-Guided Surgery, Strasbourg, France"},{"name":"Fondazione Policlinico Universitario Agostino Gemelli, IRCCS, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Domenico","family":"Di Nardo","sequence":"additional","affiliation":[{"name":"Sapienza University of Rome, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniele","family":"Pironi","sequence":"additional","affiliation":[{"name":"Sapienza University of Rome, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefano","family":"Pontone","sequence":"additional","affiliation":[{"name":"Sapienza University of Rome, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacopo","family":"Martellucci","sequence":"additional","affiliation":[{"name":"Azienda Ospedaliero-Universitaria Careggi, Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriele","family":"Naldini","sequence":"additional","affiliation":[{"name":"Santa Chiara Hospital of Pisa, Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Domenico","family":"Mascagni","sequence":"additional","affiliation":[{"name":"Sapienza University of Rome, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,3,5]]},"reference":[{"key":"bibr1-1553350620908388","doi-asserted-by":"publisher","DOI":"10.1007\/BF02237240"},{"key":"bibr2-1553350620908388","doi-asserted-by":"publisher","DOI":"10.1007\/s00384-014-1845-7"},{"issue":"4","key":"bibr3-1553350620908388","first-page":"CD005393","author":"Jayaraman S","year":"2006","journal-title":"Cochrane Database Syst Rev"},{"key":"bibr4-1553350620908388","doi-asserted-by":"publisher","DOI":"10.1007\/s10350-004-6754-3"},{"key":"bibr5-1553350620908388","doi-asserted-by":"publisher","DOI":"10.1007\/s10350-007-9171-6"},{"key":"bibr6-1553350620908388","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.5904"},{"key":"bibr7-1553350620908388","doi-asserted-by":"publisher","DOI":"10.1007\/s00384-011-1216-6"},{"key":"bibr8-1553350620908388","doi-asserted-by":"publisher","DOI":"10.1007\/s10151-008-0426-6"},{"key":"bibr9-1553350620908388","doi-asserted-by":"publisher","DOI":"10.1016\/j.asjsur.2018.05.002"}],"container-title":["Surgical Innovation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1553350620908388","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1553350620908388","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1553350620908388","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T07:21:46Z","timestamp":1777706506000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1553350620908388"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,3,5]]},"references-count":9,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2020,6]]}},"alternative-id":["10.1177\/1553350620908388"],"URL":"https:\/\/doi.org\/10.1177\/1553350620908388","relation":{},"ISSN":["1553-3506","1553-3514"],"issn-type":[{"value":"1553-3506","type":"print"},{"value":"1553-3514","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,3,5]]}}}
