AI-generated summary by claude@2026-06, 2026-06-10

This study analyzed 37 patients with post-surgical rectovaginal fistulae, finding that colostomies were associated with faster healing and that larger fistulae and pelvic sepsis predicted diversion failure.

This retrospective cohort study analyzed women with post-surgical rectovaginal fistula (psRVF) from a prospectively maintained registry at a single hospital over 2002–2016, comparing outcomes after fecal diversion and assessing timing of stoma maintenance (6 months, with additional evaluation of local fistula treatments). Of 2043 rectal resection patients, 37 (1.8%) developed psRVF; overall, 51.3% healed within 6 months (median recovery ~100 days), and concomitant local fistula treatment did not change healing rates. Multivariable analysis found diversion failure was significantly associated with fever and pelvic abscess/pelvic sepsis, while fistula size showed only borderline association with success in the context of loop stomas. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

To analyze the role of stoma diversion and timing of stoma maintenance in the healing of post-surgical Recto Vaginal Fistulae (psRVF). A retrospective analysis of a prospectively maintained registry. All patients with a psRVF diagnosed at IRCCS Sacro Cuore-Don Calabria Hospital of Negrar di Valpolicella from January 2002 to December 2016 were analyzed. The baseline treatment was a fecal diversion. Patients were divided into two groups according to healing time:  6 months (Group 2). 2043 women underwent rectal resections in the study period. We recorded 37 patients with psRVF (1.8%). Nineteen women (51.3%) healed (Group 1) within 6 months. The median time of psRVF recovery in group 1 was 99.7 days. Concomitant local treatment of the fistula did not influence the healing rate (p 0.8). Colostomies were significantly higher in group 1 (p 0.003). The size of the psRVF influenced the success rate of fistula healing with loop stoma (p 0.07). A multivariate analysis the presence of fever and pelvic abscess (pelvis sepsis) were significantly associated with diversion failure (p 0.035). A step-up approach with the maintenance of loop stoma at least for six months for all patients with psRVF could be changed. Patients with larger fistula and pelvic sepsis at index procedure should be addressed earlier to a specific second-level treatment.

The baseline treatment was a fecal diversion. Patients were divided into two groups according to healing time: 6 months (Group 2). 2043 women underwent rectal resections in the study period. We recorded 37 patients with psRVF (1.8%). Nineteen women (51.3%) healed (Group 1) within 6 months. The median time of psRVF recovery in group 1 was 99.7 days.
