Transverse coloplasty pouch and colonic J-pouch for rectal cancer - a comparative study
2003
Objectives The introduction of the colonic J-pouch has markedly improved the functional outcome of restorative rectal cancer surgery. However colonic J-pouch surgery can be problematic and may present some late evacuatory problems. To overcome these limitations a novel pouch has been proposed: the transverse coloplasty pouch. The purpose of our study was to compare the functional outcomes of these two different types of pouches – the transverse coloplasty pouch (TCP) and the colonic J-pouch (CJP) – during the first 12 months postoperatively. Patients and methods A prospective randomized trial was conducted in which a total of 30 patients with mid and low rectal cancer were submitted either to a transverse coloplasty pouch or a colonic J-pouch. Clinical defaecatory function was assessed and anorectal physiological assessment was carried out, pre-operatively and at 3, 6 and 12 months postoperatively, by means of a standard clinical questionnaire and by anorectal manometry. Results No statistically significant differences were found between the two groups regarding bowel function. The postoperative frequency of daily bowel movements was lower in the TCP group in all the phases of the study
