However, the evaluation of MRI after fistula\u2010in\u2010ano surgery has never been done. The aim was to evaluate the utility of MRI in postoperative period after fistula\u2010in\u2010ano surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Preoperative MRI was done in all the patients presenting with fistula\u2010in\u2010ano. Postoperative MRI was done to check radiological healing in clinically healed fistulas or when postoperative complication\/healing problem was seen. The postoperative MRI was compared with preoperative MRI and correlated with the clinical picture.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 1323\u00a0MRI were done in 1003 fistula\u2010in\u2010ano patients, out of which 702 patients underwent surgery. In 702 patients, there were 361 recurrent fistulas, 153 had associated abscess, 388 had multiple tracts, 146 had horseshoe tract, and 76 had supralevator fistula. In total, 320 postoperative MRI scans were done in 180\/702 patients. The requirement of postoperative MRI was significantly higher in complex (grades III\u2013V) than simple fistulas (grades I\u2013II) [43.5% (136\/313) vs. 11.3% (44\/389), respectively, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.0001]. In early postoperative period (8 weeks), healing (granulation) tissue was difficult to differentiate from active fistula tract\/pus. The complete radiological healing took at least 10\u201312 weeks. So getting MRI scan for the assessment of healing was more accurate after 12 weeks. MRI was very accurate to identify postoperative complications like abscess, missed tract or non\u2010healing of a tract. MRI detected such complications even in apparently clinically healed tracts. Closure\/healing of internal opening and intersphincteric tract was assessed accurately by MRI and correlated well with the fistula healing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>MRI is highly useful to assess healing and detect complications after fistula surgery.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00268-019-04926-y","type":"journal-article","created":{"date-parts":[[2019,1,31]],"date-time":"2019-01-31T14:52:53Z","timestamp":1548946373000},"page":"1612-1622","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Comparison of Preoperative and Postoperative MRI After Fistula\u2010in\u2010Ano Surgery: Lessons Learnt from An Audit of 1323\u00a0MRI At a Single Centre"],"prefix":"10.1002","volume":"43","author":[{"given":"Pankaj","family":"Garg","sequence":"first","affiliation":[{"name":"Indus Super Specialty Hospital Mohali India"},{"name":"Garg Fistula Research Institute 1042, Sector\u201015 134113 Panchkula Haryana India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,1,31]]},"reference":[{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00268\u2010017\u20103886\u2010x"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/DCR.0b013e318249d26c"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2391041043"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/DCR.0000000000001051"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijsu.2018.06.009"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijsu.2017.02.095"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijsu.2017.04.019"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.20.3.g00mc15623"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800630102"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12262\u2010018\u20101788\u20102"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/DCR.0000000000001053"},{"key":"e_1_2_8_13_2","doi-asserted-by":"publisher","DOI":"10.1097\/DCR.0000000000001051"},{"key":"e_1_2_8_14_2","doi-asserted-by":"publisher","DOI":"10.1097\/DCR.0000000000000593"},{"key":"e_1_2_8_15_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0191822"},{"key":"e_1_2_8_16_2","doi-asserted-by":"publisher","DOI":"10.1097\/DCR.0000000000001084"}],"container-title":["World Journal of Surgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/link.springer.com\/article\/10.1007\/s00268-019-04926-y\/fulltext.html","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/link.springer.com\/content\/pdf\/10.1007\/s00268-019-04926-y.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/link.springer.com\/content\/pdf\/10.1007\/s00268-019-04926-y.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"similarity-checking"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1007\/s00268-019-04926-y","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,10]],"date-time":"2024-01-10T23:23:54Z","timestamp":1704929034000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1007\/s00268-019-04926-y"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,1,31]]},"references-count":15,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2019,6,15]]}},"alternative-id":["10.1007\/s00268-019-04926-y"],"URL":"https:\/\/doi.org\/10.1007\/s00268-019-04926-y","archive":["Portico"],"relation":{},"ISSN":["0364-2313","1432-2323"],"issn-type":[{"value":"0364-2313","type":"print"},{"value":"1432-2323","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,1,31]]},"assertion":[{"value":"31 January 2019","order":1,"name":"first_online","label":"First Online","group":{"name":"ArticleHistory","label":"Article History"}},{"order":1,"name":"Ethics","group":{"name":"EthicsHeading","label":"Compliance with ethical standards"}},{"value":"All authors have declared that they have no conflicts of interest.","order":2,"name":"Ethics","group":{"name":"EthicsHeading","label":"Conflict of interest"}}]}}
