Abstract

BACKGROUND AND PURPOSE

The functional outcomes of incontinence and high stool frequency resulting from restorative surgery are often criticised. The aim of this study was to assess the taeniectomy pouch in comparison with other pouches described in the literature.

MATERIAL AND METHODS

This was a prospective cohort study. All patients who were candidate for low rectal resection presenting to the colorectal unit at Cairo University hospitals during the period February 2013 to February 2015 were included in the study (90 patients). Safety and feasibility of the new technique were assessed, including operative time, leakage, postoperative urgency, incontinence, number of daily motions and difficulty in evacuation. These parameters were assessed clinically, by means of defecography and anorectal manometry.

RESULTS

The mean age of patients was 49.6 years. Percentages of postoperative mortality and leakage were 2.2% and 3.4%, respectively. Mean operative time was 117 minutes. Mean numbers of daily motions were 3.04 and 1.52 at 3 and 12 months, respectively. Mean Wexner score for continence at 3 and 12 months were 3.21 and 1.32, respectively. Mean resting pressure was 51.63 mmHg, squeeze pressure was 130.42 mmHg and mean threshold volume was 118.68 ml.

CONCLUSIONS

Taeniectomy is a novel technique for pouch formation after low rectal resection, which can be used as an alternative to other pouches, especially the widely used transverse coloplasty.
