Short Occult Retractile Fibrous Scar Causing Exclusive Retrograde Stenosis of the Sigmoid Colon: An Incidental Diagnosis Nineteen Years After a Single Episode of Colonic Diverticulitis

We report a rare case of purely retrograde stenosing stricture of the sigmoid descending colonic junction fortuitously diagnosed during the waning of a failed virtual colonoscopy in a 69-year-old patient. The rather asymptomatic patient was addressed to investigate a positive fecal occult blood test. He had suffered a single acute colonic diverticulitis episode 19 years before. A contrast-enhanced abdominal CT and complementary focused abdominal ultrasound fully diagnosed a short curvilinear contrast-enhancing “scar-like” tissue infiltrating the posterior colonic wall and developing retractile adherences with the retroperitoneum of the left iliac fossa. The imaging features are presented with pathologic correlation

Measure of the voluntary contraction of the puborectal sling as a predictor of successful sphincter repair in the treatment of anal incontinence

PURPOSE: Overlapping sphincteroplasty is the surgery of choice for incontinent patients with an anterior defect after childbirth. Numerous predictive factors have been proposed, but no preoperative variables have been successfully shown to be reproducible. The purpose of this study was to assess the prognostic value of voluntary contraction of the puborectal sling before sphincter repair for anal incontinence. METHODS: This prospective study evaluated 109 consecutive women who underwent surgery for postobstetric anal incontinence. Voluntary contraction of the puborectal sling was measured by perineal ultrasound before the surgery. Severity of anal incontinence was evaluated preoperatively and postoperatively with the Miller Incontinence Score (total incontinence = 18, complete continence = 0). RESULTS: The proportion of patients with scores ≤ 3 was 16.7 percent when the preoperative voluntary contraction of the puborectal sling was ≤ 4 mm, 48.1 percent when it was 4.1 to 8 mm, and 98.7 percent when it was >8 mm (P 8 mm convincingly discriminates between patients with a good functional outcome and those with an unsatisfactory outcome after sphincter repair for postobstetric anal incontinence
