Common Tests for the Pelvic Floor

Treatment of Difficult-Obstructive Defecation

Unpacks Obstructive Defecation Syndrome (ODS), starting with the absolute necessity of pelvic floor biofeedback over surgical intervention for dyssynergic defecation. It details the strict millimeter-based grading systems for structural defects like rectoceles and enteroceles. The operative discussion highlights the abandonment of the STARR procedure due to a 40% long-term recurrence rate, instead favoring laparoscopic ventral mesh rectopexy for internal prolapse and transvaginal native tissue repairs for rectoceles.

Evaluation of Constipation and Treatment of Abdominal Component

Explores the diagnostic and surgical algorithms for chronic refractory constipation. It clearly differentiates slow transit constipation (colonic inertia) from IBS-C utilizing the 5-day radiopaque marker study rule (retention of >20% markers). The episode breaks down the latest pharmacotherapy, including secretagogues and PAMORAs for opioid-induced constipation, and thoroughly dissects the significant morbidity, incontinence risks, and patient selection criteria for a total abdominal colectomy with ileorectal anastomosis (TAC-IRA).

Common Tests for the Pelvic Floor

A deep dive into the physiological and mechanical evaluation of pelvic floor disorders. The episode examines the hardware evolution of manometry from water-perfused catheters to high-resolution systems, and the standardization of dyssynergic defecation phenotypes via the London Protocol. It also reviews the diagnostic utility of the balloon expulsion test and compares the true physiological advantages of sitting fluoroscopic defecography against the anatomical clarity of supine MRI defecography.

Functional Disorders After Colorectal Surgery - IBS

Focuses on distinguishing and managing Irritable Bowel Syndrome using the rigid Rome IV criteria. It issues a stark warning against operating on functional visceral hypersensitivity, detailing how elective resections for symptomatic uncomplicated diverticular disease frequently fail to relieve pain. The episode reviews targeted pharmacotherapy based on IBS subtypes (e.g., eluxadoline for IBS-D and lubiprostone for IBS-C), and addresses pelvic floor pain syndromes like proctalgia fugax, which surprisingly responds to inhaled albuterol.

Abdominal Wall Reconstruction and Parastomal Hernia

Tackles the inevitable biomechanical failure of parastomal hernias, which eventually affect nearly all permanent stoma patients. It emphasizes strict preoperative optimization goals, including a BMI under 35, an A1C under 8, and absolute smoking cessation. The discussion covers the mechanical superiority of the Sugarbaker mesh drape geometry over the keyhole technique, and explores advanced retromuscular/TAR (Transversus Abdominis Release) approaches utilizing macroporous uncoated synthetic mesh in contaminated fields.
