Sacral nerve stimulation in patients after rectal resection--preliminary report.

Introduction: Sacral nerve stimulation is a widely accepted therapeutic option for neurogenic fecal incontinence. More recently, case reports showed a positive effect of sacral nerve stimulation in patients with fecal incontinence following low anterior resection. The purpose of this study was to gain more information for this selected indication for sacral nerve stimulation through a nationwide survey.

Technique and long-term results of intersphincteric resection for low rectal cancer.

Purpose: Intersphincteric resection of low rectal tumors is a surgical technique extending rectal resection into the intersphincteric space. This procedure is performed by a synchronous abdominoperineal approach with mesorectal excision and excision of the entire or part of the internal sphincter. This study was designed to evaluate the long-term results of this method focused on continence function and oncologic results.

Magnetic resonance imaging predicts sphincter invasion of low rectal cancer and influences selection of operation.

Background: With the development of numerous sphincter-saving surgical techniques in the last 2 decades, the indication for abdominoperineal resection in radical-elective operations has been markedly reduced. The preoperative assessment of the extent of local tumor growth is essential for the planning of the optimal surgical procedure. Magnetic resonance imaging (MRI) proved to be a reliable method for local staging of low rectal carcinoma.
