The judgment criteria combined asymptomatic status plus clinical occlusion of the fistula tract and MRI-confirmed healing of the tract (no inflammation and\/or disappearance of the tract). Both clinical and MRI-confirmed healing of the tract defined a deep remission. Clinical remission was defined by an absence of complaint, occlusion of all external openings, and no fistula discharge.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>A total of 116 patients were extracted (median follow-up after cell stem injection: 11 [6-14] months). No severe adverse events were reported after surgery except for subsequent anal surgery in 29 (25%) patients. Fifty-one (44%) patients had clinical remission defined by the absence of complaints, the occlusion of all external openings, and the presence of no fistula discharge. Deep remission was observed in 23 (29%) patients. Patients with clinical remission more often received combined therapy (immunosuppressant antitumor necrosis factors) than those with no improvement (31 of 51 [61%] vs 23 of 65 [35%]; P = .007). Regression analysis showed that high fistulas (odds ratio, 3.8 [1.1-12.5]; P = .03) and younger age (&amp;lt;38 years, odds ratio, 2.3 [1.0-58;4]; P = .02) were associated with a better
