In brief
Chronic enema use in 22 patients with fecal incontinence (average 13.7 years) caused severe right colon dilatation and left colon spasm, producing progressive colicky pain and delayed transit. This previously unreported complication occurred across multiple enema formulations and underlying diagnoses including anorectal malformations and myelomeningocele.

Abstract
Background/purpose
Enemas have become a common practice for treating fecal incontinence and severe constipation. Several patients receiving enemas complained of severe, colicky, abdominal pain during enema administration and complained that the duration for fluid to pass was progressively increasing. Contrast studies showed a startling picture of severe right colon dilatation and a spastic, narrow, left colon. An investigation was started to seek the origin and possible management of this condition.
Methods
Medical and radiologic records were reviewed retrospectively, with emphasis on the type and ingredients of enemas used, the duration the patients had been receiving enemas, and their original diagnosis. A literature review was done on previous reports of this condition and publications related to long-term use of enemas.
Results
This series included 22 patients (average age, 19.6 years; range, 8–54) with fecal incontinence due to anorectal malformations (10 cases), myelomeningocele (5), cloaca (2), severe colonic dysmotility (2), Hirschsprung's disease (2), and sacrococcygeal teratoma (1). The average duration of enema use was 13.7 years (range, 4–45). The composition of the enemas included saline/glycerin (six cases), only saline solution (five), saline/glycerin/soap (four), plain water (three), and one case each of molasses/milk, saline/glycerin/soap/phosphate, saline/phosphate, and only phosphate. The enemas were performed in an antegrade fashion in 21 cases and rectally in 1. All patients had a dilated right colon and a narrow, spastic, left, transverse, and descending colon. Four patients underwent colonoscopy, colonic manometry, and mucosal biopsies, which did not help in explaining the etiology of the problem. In the literature, 43 reports mentioned a "long-term follow-up" for the administration of enemas, but we could not find a description of symptoms, such as in our cases.
Conclusions
An intriguing and, to our knowledge, previously unreported complication of chronic enema use is presented. We call attention to an overly concerning complication and report our findings in the hope that they will aid and stimulate more investigations into this condition. Several hypotheses to explain the cause are presented, as well as potential treatment options.
