Stapled transanal rectal resection: a new surgical treatment for obstructed defecation syndrome.

Background: Rectal intussusception, rectocele and rectal prolapse are anatomic disorders in obstructed defecation syndrome. A relatively new surgical approach, Stapled Transanal Rectal Resection, was designed to treat these anomalies.

Objectives: To present our preliminary results with this technique.

Resting anal pressure following hemorrhoidectomy and lateral sphincterotomy.

Purpose: The role of high anal pressure in the pathophysiology of hemorrhoids and anal fissures is debated. We compared resting anal pressures following left lateral sphincterotomy and hemorrhoidectomy in a prospective manometric study with emphasis on the recovery of the internal anal sphincter activity.

Methods: Included in the study were 38 patients with third-degree or fourth-degree symptomatic hemorrhoids who underwent hemorrhoidectomy, 50 patients with anal fissure who underwent sphincterotomy, and 12 healthy patients who served as controls.

Internal anal sphincter function following lateral internal sphincterotomy for anal fissure: a long-term manometric study.

Background: Anal fissure is a common and painful disorder. Its relation to hypertonic anal sphincter is controversial. The most common surgical treatment of chronic anal fissure is lateral internal sphincterotomy.

Long-term follow-up and factors influencing success of silastic ring vertical gastroplasty.

Background: Careful selection of patients for the operation plays a major role in long-term results of silastic ring vertical gastroplasty. The objective of the current study is to identify predictive factors for the objective (excess weight loss) and subjective (satisfaction) success of silastic ring vertical gastroplasty (SRVG) for morbid obesity.

Design: Retrospective cohort study.
