Pouchogram Prior to Ileostomy Reversal after Ileal Pouch-Anal Anastomosis in Pediatric Patients: Is it Useful in the Setting of Routine EUA?

PURPOSE

To determine if there is a role for routine pouchogram before ileostomy reversal after IPAA in pediatric patients.

METHODS

The medical records of pediatric patients who underwent pouchogram between 2007 and 2017 prior to ileostomy reversal after IPAA at two affiliated hospitals were reviewed for concordance between exam under anesthesia (EUA) and pouchogram findings, management of abnormal pouchogram findings, and short and long-term outcomes after ileostomy reversal. Clinical notes were used to find patient-reported symptoms at the time of pouchogram.

RESULTS

Sixty patients (57% female) underwent pouchogram before planned ileostomy reversal. The median time from IPAA formation to pouchogram was 60.5 days (IQR: 46-77) and median follow-up was 4 years (IQR: 1-6). Fifty-seven patients (95%) were asymptomatic prior to reversal. Of the 40 asymptomatic patients with a normal EUA, pouchogram detected one stricture (3%), but reversal proceeded as planned. In the 16 patients with strictures on EUA, pouchogram only detected six (40%). One of 50 (2%) asymptomatic patients with normal pouchogram had anastomotic dehiscence found on EUA. Despite normal pouchogram and EUA, four asymptomatic patients required subsequent diversion for pouch-related complications between 13 and 60 months after ileostomy reversal. Three patients had pelvic pain prior to pouchogram; associated symptoms included perineal pain (n = 1) hematochezia (n = 1), and tenesmus (n = 1). EUA and pouchogram were concordant in two patients (n = 1 anastomotic complication, n = 1 pouch septum) and ileostomy reversal was delayed. In the remaining symptomatic patient, pouchogram detected an anastomotic leak where EUA detected only a stricture, and this prompted a delay in reversal. Long term, none of these patients required diversion or excision of their pouch.

CONCLUSION

Routine pouchogram in asymptomatic pediatric patients does not change management and can be omitted, thereby sparing patients discomfort and unnecessary radiation exposure. Pouchogram may have diagnostic value in symptomatic patients.

Enterostomy closure timing for minimizing postoperative complications in premature infants

BACKGROUND

For premature infants with advanced acute abdomen, creating a temporary enterostomy is believed to be an appropriate surgical management. However, there is no consensus regarding the timing of enterostomy reversal. The aim of this study was to determine the optimal timing for enterostomy closure (EC) by analyzing EC-related complications.

METHODS

This was a retrospective study of preterm infants who underwent enterostomy for suspected acute abdomens and subsequent closure.

RESULTS

EC-related complications occurred in 35 of 54 infants (65%). A univariate analysis determined the following risk factors for EC-related complications: lower weight and younger age at the time of EC and a shorter stoma duration. In a multiple logistic regression analysis, the only significant risk factor was a weight under 2660 g at the time of the closure operation. Infants with EC-related complications were ventilated longer, were administered more vasopressors, and were more likely to undergo reoperation. Additionally, these infants required parenteral nutrition for a longer duration, had a longer length of hospital stay after EC, and had a significantly lower weight and height at a corrected age of 7-10 months than infants without EC-related complications.

CONCLUSION

Body weight may be one of the most important factors to consider for minimizing EC-related complications.
