Long-term results of total colonic agangliosis patients treated by preservation of the aganglionic right hemicolon and the ileo-cecal valve.

PURPOSE: In 1989, Sauer introduced a technique to treat patients with total colonic aganglionosis (TCA) where he preserved the ileo-cecal valve and the right hemicolon to retain water and electrolyte absorption. This report examines the long-term outcome of patients who underwent this technique.
METHODS: All TCA patients treated between 1981 and 2005 according to Sauer were invited in 2013 to participate in a questionnaire survey to assess their long-term outcome focusing on bowel function and quality of life (QoL), using standardized scores.
RESULTS: Of eight TCA patients (2 females, 6 males), seven participated in the follow-up survey (median follow-up time 13.5 years (range 8-31.6). Early postoperative complications involving bouts of enterocolitis in 3 and anal strictures in 5 patients ceased with age. Bowel movements ranged from median 3-4 times a day (range 1-8). Bowel-function score (BFS) was reduced in 6 patients (median 16 points, range 8-19, max 20), who also reported soiling incidences with the need for night-time protective aids in two. QoL assessment, however, documented a good outcome with a median score of 10 points (range 7-13, max 13).
CONCLUSION: This long-term investigation of TCA patients treated according to Sauer's technique documented a good QoL despite a reduced BFS.
