[The colon-J-pouch anal reconstruction following total rectum resection: functional aspects].
Coloanal reconstruction is a sphincter saving operation following total rectal resection to treat rectal cancer 3 to 11 cm above the dentate line. Total rectal resection in this situation is justified from the oncological and surgical viewpoint because the local recurrence rate and morbidity are not different from the "gold standard", abdominoperineal resection sacrificing the anal sphincter. Although patients undergoing straight coloanal reconstruction preserve continence, they are often disturbed by high stool frequencies and imperative urge. We set out to establish whether construction of a colon-j-pouch could ameliorate the quality of defecation and thus prove useful. In this study the pre- and postoperative results of a pilot study with 4 consecutive patients following colon-j-pouch-anal reconstruction are presented. Perioperatively, 3 of 4 patients suffered from intermittent disturbances of urinary voiding. Sexual function was disturbed in 3 of 4 patients. All patients were completely continent. The preliminary results showed a decreased sphincter pressure at rest of 40 mm Hg (SD: 5) and a normal squeeze pressure. Endoanal ultrasound demonstrated a normal anal sphincter morphology. Pouch compliance yielded 4.7 ml/cm H2O and was better than after straight coloanal reconstruction in the control group (2.8 ml/cm H2O). The stool frequency at 6 months was 3/24 hours without imperative urge. The colon transit time lasted 49 hours and was in the normal range. No pouch evacuation disorders were observed. These results show a minimal morbidity in colon-j-pouch-anal reconstruction with preservation of complete continence in the follow-up time.(ABSTRACT TRUNCATED AT 250 WORDS)
