The histopathology of anal fistula tract epithelial lining of every operated patient was analyzed and other tests (real-time-polymerase chain reaction [RT-PCR], GeneXpert, and mycobacterial culture) were conducted in patients with high index of suspicion of having mycobacterial disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Two patients had histopathological features suggestive of mycobacterial disease.

Four patients had normal histopathology features but tested positive on RT-PCR (2 each for NTM and MTB). Therefore, a total of six patients were tested for mycobacterial disease (3 each for NTM and MTB). Mycobacterium culture was performed in two patients (both NTM) but the result was negative. Five of six patients (NTM = 2, MTB = 3) presented with delayed recurrences after operation (6\u201318 months after complete healing).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>NTM can cause fistula-in-ano. It could be an undiagnosed contributory factor in fistula recurrence. Mycobacterial disease (both tuberculous and nontuberculous) may be associated with delayed recurrence of fistula. RT-PCR is highly sensitive and can differentiate between NTM and MTB. It should perhaps be performed in all recurrent and refractory cases.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijmyco.2016.05.001","type":"journal-article","created":{"date-parts":[[2016,6,2]],"date-time":"2016-06-02T05:41:06Z","timestamp":1464846066000},"page":"276-279","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":10,"title":["Nontuberculous mycobacteria in fistula-in-ano"],"prefix":"10.4103","volume":"5","author":[{"given":"Pankaj","family":"Garg","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-6-20260911","doi-asserted-by":"crossref","first-page":"257","DOI":"10.1007\/s15010-004-4001-4","article-title":"Nontuberculous mycobacterial infections: a clinical review","volume":"32","author":"Wagner","year":"2004","journal-title":"Infection"},{"key":"R3-6-20260911","first-page":"46","article-title":"Perianal ulcers of tubercular origin.
