Abstract

Different pouch designs and techniques for the perineal approach have been on trial in an attempt to improve results after restorative proctocolectomy. The 1-year results of two currently advocated procedures, the J-pouch and the S-pouch, were compared with the results obtained in patients with a pelvic pouch fashioned according to the folding technique used for the Kock continent ileostomy, all pouches having been constructed from equal 30 cm lengths of ileum. The maximal volume of the S- and Kock pouches at one year was 420 ml (250-570) (median and (range] and 410 ml (244-490) respectively, while it was significantly less, 305 ml (200-445) in the J-pouch (p less than 0.05). The compliance of the J-pouches was also significantly lower at all distension pressures. The median day-time defaecation frequency was four and was equal in the three groups. Although there was a tendency towards a more favourable overall functional result with less soiling, and less need for night evacuations among patients with a Kock-folded pouch compared to the other pouch types these differences failed to reach statistical significance. The favourable properties of the Kock pouch, well-known also from the conteinent ileostomy and urostomy, suggest that its design should be considered an interesting alternative even for restorative proctocolectomy. These encouraging results have yet to be confirmed in a comparative randomized trial.
