Pelvic Floor- A 75-year-old female patient with fecal incontinence presents for stage 1 sacral neuromodulation. Upon lead stimulation, which of the following findings would be associated with optimal lead position?
- A 58-year-old woman presents with longstanding history of constipation. She has tried medical management without success. She relates that she has successfully altered bowel texture, but she still strains to pass gas or liquid stool and needs at times to manually disimpact. Colonoscopy was normal. A sitz marker study image and fluoro defecography video are shown below. Her clinical presentation represents
- A 73-year-old woman presents with increasing difficulty with defecation that requires significant straining, minimal passage of stools, and a sensation of incomplete evacuation. Trials of lifestyle change, laxatives, and biofeedback therapy have all been successful in improving symptoms. Under normal circumstances during defecation (i.e., normal physiologic conditions), the anorectal angle

- A 46-year-old woman presents with rectal pain of 6 months’ duration. Findings of direct and digital examination followed by anoscopy are negative except for severe pain on palpation over the left puborectalis sling. What is the best next step in management?
- A 45-year-old woman with a history of chronic constipation is evaluated in the office. Recent transit study demonstrated retention of 16 Sitz markers scattered throughout the colon 5 days after ingesting the Sitzmark capsule. Colonoscopy findings are unremarkable. She has failed multiple medication trials. She is compliant with her dietary modifications such as fiber and fluid intake. She takes a commercial polyethylene glycol 3350 formulation as needed. What is the most appropriate next step in management?
