[Small left colon syndrome: a review of our experience]

The object is to present our experience with the small left colon syndrome (SLCS) and to investigate the usefulness of the anorrectal manometry in the study of these patients.

This was a retrospective review of the clinical histories of 10 patients treated in our Hospital for SLCS. The following variables are valued: sex, mother precedents, type of childbirth, gestational age, birth weight, clinical presentation (low colonic obstruction), delayed meconium passage, contrast enema with gastrografin, anorrectal manometry and treatment (Nursing, days of digestive rest, time of parenteral nutrition).

During the study period, 10 patient were identified (5 are men). SLCS is reported in 2 sets of twins; in one set both twins are affected and in the other set 1 twin is affected. Maternal diabetes was identified in 6 patients. The mean gestational age was 36.6 + 2.11 weeks, and the weight 3001 +/- 689.72 g. 2 patient presented anomalies associated: fetopatía diabetic, hemivértebras D11-L2. All 10 infants presented abdominal distention and vomiting at 48.73 +/- 45.39 hours of life. Only 2 presented meconium passage in the first 24 hours. The contrast enema with gastrografin performed show typical findings of this syndrome in all cases. The anorrectal manometry carries out in 8 patients and demonstrates presence of the recto-anal inhibitory reflex (RAIR) in 5 and absence in 3. In these 3 patients with no RAIR, the study was repeated weekly until the presence being observed (normally between 2a and 3a week of life). In 1 newborn was necessary colostomy; the suction rectal biopsy showed immaturity of ganglionars cells and the manometric control previously at the close of the colostomy (9 months) showed presence of the RAIR. Conservative treatment (nursing and digestive rest) was successful in all cases with a mean of duration the 6.40 +/- 5.10 days. 6 patient needed parenteral nutrition during 7.30 +/- 8.49 days. The mean of discharge was 17.78 +/- 13.28 days. The clinical development was favourable in all the cases.

The contrast enema with gastrografin is diagnostic and therapeutic and together with the nursing, has allowed solve the distal intestinal obstruction in 9 cases (90%). In the newborns with absence of RIAR, the anomanometric controls have allowed to know the moment of the maturation of the anorectal function.
