Five Years' Single-center Experience of a Modified Approach to Divided Sigmoid Colostomy for Anorectal Malformation

In patients with anorectal malformation (ARM), a divided descending colostomy is associated with high complication rates, including wound infection, dehiscence, and prolapse, and it places a significant burden on caregivers. To decrease the chances of such complications, we modified our approach for colostomy fashioning by keeping an intact skin bridge between the colostomy and mucous fistula. The objective was to compare the rate of complications among patients diagnosed with ARM who underwent a modified divided descending colostomy and classical descending colostomy.

We included all the patients diagnosed with ARM who underwent a divided colostomy with modified (group A) or classical technique (group B) in the last 5 years. The type of approach used to fashion the stoma was based on the surgeon's preference than on patients' selection criteria. All patients were followed and monitored for postoperative complications. SPSS version 26 was used to analyze the data.

A total of 62 patients with ARM underwent the colostomy creation; 27 in group A and 35 in group B. Males were more in both groups and other demographic variables were comparable. The most common associated anomalies were cardiac (58%). The mean duration of surgery was 72.2 ± 18.26 min in group A while 91.25 ± 21.43 min in group B (P = 0.000). The mean hospital stay was 4.28 ± 3.63 days in group A while 7.97 ± 6.12 days in group B (P = 0.007). The overall complication rate was 14.8% in group A and 34.2% in group B (P = 0.082).

The modified approach to fashioning a divided colostomy is easily reproducible and carries a low risk of postoperative complications.
