Proctocolectomy and J-pouch ileo-anal anastomosis in children.

BACKGROUND/PURPOSE: The choice of ileo-anal reconstruction method in children undergoing proctocolectomy remains controversial. Although in adults ileo-anal pouch reconstruction has gained overall acceptance, many paediatric surgeons still advocate straight ileo-anal pull-through. The aim of this study was to assess the outcome and long-term functional results in children who have undergone proctocolectomy and ileo-anal anastomosis (IAA) with a J-pouch. METHODS: Medical records of 40 consecutive children who had proctocolectomy and J-pouch IAA between 1991 and 1999 were reviewed for early and late complications, fecal frequency, day- and night-time continence, and pouchitis. The indication for surgery was ulcerative colitis (UC) in 29 (median age at operation, 13 years; range, 9 to 16), Hirschsprung's disease (HD) in 10 (median age at operation, 1.5 years; range, 1 month to 5 years), and familial adenomatous polyposis (FAP) in 1 (age at operation, 6 years). Six of the HD patients had primary pull-through for total colonic aganglionosis and 4 a redo operation for failed primary reconstruction of long segment aganglionosis. RESULTS: There were no fatalities. Early complications (wound infection, early bowel obstruction, prolonged fever) occurred in 12 of 29 (41%) and late complications (bowel obstruction 9, pouch fistula 2) in 11 of 29 (38%) of the UC patients. Overall, 16 of 29 (53%) of the UC patients had complications. All patients with early complications were on systemic steroids at the time of the operation. Pouchitis occurred in 30% of the patients. None of the pouches had to be removed. At last follow-up all patients were continent during the day, 2 patients used protective pads during the night because of occasional staining. The median bowel frequency per 24 hours was 4 (range, 2 to 7); only 2 patients (7%) had to empty their bowel during the night. One (10%) of the HD patients had wound infection, and 3 had episodes of postoperative enterocolitis. Pouchitis-type symptoms have not occurred in HD patients. The median bowel frequency for 24 hours was 3 (range, 2 to 5). None of the HD patients needs to evacuate during the night. The 4 HD patients who are older than 3 years of age are continent. CONCLUSIONS: J-pouch IAA is a feasible method of reconstruction in children requiring proctocolectomy. Major complication are common but occur mainly in immunosuppressed patients suffering from UC. Despite high incidence of complications, long-term functional results in terms of continence and bowel frequency are excellent and ensure good quality of life in the great majority of patients.

Fecal continence in patients having undergone posterior sagittal anorectoplasty procedure for a high anorectal malformation improves at adolescence, as constipation disappears.

BACKGROUND/PURPOSE: Constipation is a major complication in patients who have undergone posterior sagittal anorectoplasty (PSARP) operation for a high anorectal malformation. Overflow incontinence is the main cause of fecal soiling in these patients. The aim of this study was to outline the natural history of constipation in patients with high anorectal malformations and relate this to the functional outcome at the end of the patient's growth period. METHODS: The study group consisted of 22 pubertal or postpubertal patients (median age 15; range, 13 to 25) with high or intermediate anorectal malformations repaired by PSARP procedure. The patients have been followed-up since birth. Constipation was defined as a need to use medical treatment or diet to ensure bowel emptying. Continence was classified as follows: grade 1, no soiling in any circumstances; grade 2, staining less than once a week, no fecal accidents; grade 3, staining more than once a week, no fecal accidents; grade 4, daily soiling or accidents, need for regular enemas, or the antegrade colonic enema procedure. All patients underwent anorectal manometry and magnetic resonance imaging of the spine and spinal cord. RESULTS: At the time of the study 2 (9%) of the 22 study group patients had constipation, but 15 (68%) had been constipated before puberty. Eleven patients (50%) were fully continent (grade 1) without constipation. Six of those had a history of constipation associated soiling. Three patients (14%) had occasional staining (grade 2) and no constipation. Two of them had been constipated with significant soiling before the onset of puberty. In the 5 (22%) patients with frequent staining (grade 3) the degree of soiling had decreased after the disappearance of constipation. Two of the 3 patients with poor outcome (grade 4) require regular enemas for recalcitrant constipation. Spinal cord anomalies were detected in 4 and abnormal sacrum in 15 patients. Of the anorectal manometric parameters, only the force of voluntary sphincter squeeze correlated with the functional result. CONCLUSION: In the majority of patients who underwent PSARP procedure for high anorectal malformation, constipation disappears at adolescence, and this is associated with improved fecal continence outcome.

Posterior sagittal anorectoplasty is superior to sacroperineal-sacroabdominoperineal pull-through: a long-term follow-up study in boys with high anorectal anomalies.

BACKGROUND/PURPOSE: It is unclear which surgical method offers best long-term functional results in patients with high anorectal anomalies. The purpose of this study was to compare the long-term outcome of sacroperineal-sacroabdominoperineal pull-through (SP-SAP) to that of posterior sagittal anorectoplasty (PSARP). METHODS: Only boys with high anorectal anomalies (rectourethral fistula) were included in the study to get fully comparable patient groups. From 1975 to 1987, 36 consecutive patients underwent anorectal reconstruction: 19 had SP-SAP (1975 to 1983) and 17 PSARP (12 with internal sphincter-sparing technique, 1983 to 1987). The late bowel function (age at follow up, SP-SAP, 19 years; range, 15 to 22; PSARP, 13 years; range, 10 to 19) was evaluated by clinical interview and examination, and anorectal manometry. RESULTS: Six (35%) of the PSARP patients and one (5%) of the SP-SAP patients (P < .04) were always clean without any adjunctive measures. Three PSARP patients and two SP-SAP patients stayed clean with daily enemas. In the PSARP patients with soiling, the median frequency of soiling episodes in a month was four (range, 1 to 16), in the SP-SAP patients, 20 (range, 2 to 28, P < .001). None of the SP-SAP patients but 8 of 17 of the PSARP patients had constipation requiring diet or oral medication. Two PSARP patients and four SP-SAP patients had occasional faecal accidents. The median daily bowel movements in the PSARP group was one (range, one to four) and in the SP-SAP group, three (range, one to five, P < .001). The PSARP patients had significantly higher anorectal resting and squeeze pressures and voluntary sphincter force (cm/H2O, PSARP: mean resting, 47+/-9; mean squeeze, 106+/-29; mean voluntary sphincter force, 60+/-22; SP/SAP: mean resting, 27+/-10; mean squeeze, 68+/-22; mean voluntary sphincter force, 41+/-17; P < .01). Thirteen (76%) of the 17 PSARP patients and none of SP-SAP patients had positive rectoanal reflex indicating functional internal sphincter. CONCLUSIONS: In boys with high anorectal anomalies, PSARP clearly is superior to sacroperineal and sacroabdominoperineal pull-through in terms of long-term bowel function and faecal continence.

Do children with repaired low anorectal malformations have normal bowel function?

PURPOSE: The authors' aim was to compare bowel function in patients who had undergone repair of a low anorectal malformation with that of normal healthy children. METHODS: The bowel function of 40 patients (29 boys, 11 girls; median age, 7; range, 3 to 13) with low anorectal malformations was evaluated by a multivariate scoring method based on a questionnaire. All patients were toilet trained for defecation and micturition. They were also evaluated clinically, and the outcome was graded as excellent (normal bowel function), good (no or minor social limitations), fair (marked social limitations), or poor (total incontinence). Fifty-four healthy children with a similar age and gender distribution were used as controls. RESULTS: Twenty-one patients (52%) with normal bowel function had continence scores within the range of the scores of healthy children (patients, 19.3 +/- 0.7 v controls, 19.1 +/- 1.3). Fifteen patients had a good clinical outcome. The mean score in this group was 16.3 +/- 2.4. Four patients with a fair outcome had a mean score of 10.5 +/- 2.9. Constipation requiring dietary or medical treatment was reported by 17 patients (42%) and four of the controls (7%). Daily soiling caused by fecal overflow was reported by four patients (10%) and none of the controls. None of the patients had urinary incontinence; occasional wetting was found in 27% of the patients and 22% of the controls (P = .56). CONCLUSION: Only half of the children with a low anorectal malformation have age-appropriate normal bowel function. Long-term follow-up of these patients to manage the main functional problem, constipation, is warranted.
