Outcomes of Initial Subtotal Colectomy for Pediatric Inflammatory Bowel Disease

A Complicated Matter: Predictors for Postoperative Infections After Bowel Resection in Pediatric Inflammatory Bowel Disease

INTRODUCTION

Children with inflammatory bowel disease (IBD) need surgery whenever medical therapy fails. The postoperative course is frequently accompanied by symptoms suggestive of infection, such as fever. The aim of our study was to analyze the postoperative course after bowel resection in pediatric IBD patients in relation to postoperative infections.

METHODS

All our pediatric IBD patients who underwent a bowel resection between 2012 and 2022 were retrospectively reviewed. Clinical data regarding surgery and the postoperative course were analyzed. The primary outcomes were signs and symptoms indicative of infection, such as fever, surgical site infection, and abscesses.

MAIN RESULTS

One hundred patients underwent an IBD-related resection, of whom 69 for Crohn's disease. A total of 42 postoperative infections occurred in 26 patients, most commonly a superficial surgical site infection (38 %). Out of 48 patients who experienced postoperative fever, 52 % had an actual infection, compared to 2 % of those without fever (p < 0.001). Preoperative use of immunomodulating therapy was not associated with higher complication rates. In 35 of 48 patients with fever (73 %) laboratory tests were done as a consequence of postoperative fever, with no differences in complication rates between patients with extremely high (>200 mg/L) and high (<200 mg/L) C-reactive protein levels.

CONCLUSIONS

Occurring in over a quarter of patients, postoperative infections are common in children after undergoing IBD-related bowel resection. Postoperative fever is indicative of an infection in half of the patients. Laboratory tests, such as serum C-reactive protein, do not seem to contribute to differentiating between complicated and non-complicated course after surgery in these patients.

When and Where Should Surgery Be Positioned in Pediatric Inflammatory Bowel Disease?

Surgery for children and adolescents with IBD is often thought of as a combination of a failure of medical management and the only option for the severe complications of the disease such as uncontrolled GI bleeding, perforation, fistulae, sepsis, and bowel obstruction. However, in CD, surgery can sometimes be an appropriate option to control disease progression, improve symptoms, allow children to get back on the growth curve, and avoid the toxicities of prolonged use of steroids. In UC, the decision to operate is theoretically curative but the long-term options mandate either intestinal continuity with an ileal pouch or a lifelong ileostomy, both of which can have significant impacts in patients' quality of life.

Does surgical approach matter in the treatment of pediatric ulcerative colitis?

BACKGROUND

This study aims to compare the morbidity of open versus laparoscopic colectomy or proctocolectomy for pediatric patients with ulcerative colitis (UC) using national readmission outcomes.

MATERIALS AND METHODS

The 2010-2014 Nationwide Readmissions Database was used to identify patients < 18 years (excluding newborns) who underwent colectomy or proctocolectomy for UC. Patients with planned readmissions for staged procedures were excluded from readmission analysis. Demographics, hospital factors, and outcomes were compared by operative approach (open vs. laparoscopic) using standard statistical analysis. Results were weighted for national estimates.

RESULTS

There were 1922 patients (51% female, age 13 ± 3 years) with UC who underwent colectomy or proctocolectomy during index admission. Most cases were performed open (54%) and as elective admissions (64%). Compared to open approach, laparoscopy was associated with shorter index hospital length of stay (8 [5-17] days vs. 9 [6-18] days, p = 0.015), fewer surgical site infections (< 2% vs. 2%, p = 0.022), and less post-operative gastrointestinal dysfunction (5% vs. 8%, p = 0.008). After stratifying to control for elective and unplanned index admissions, laparoscopic approach was associated with fewer small bowel obstructions during index hospitalizations in both elective (9% vs. 15%, p = 0.003) and unplanned (5% vs. 16%, p<0.001) settings. Readmission for surgical site infection was also less common following laparoscopic approach in both elective (0% vs. 7%, p = 0.008) and unplanned (0% vs. < 7%, p = 0.017) settings.

CONCLUSIONS

In pediatric patients with ulcerative colitis, laparoscopic colectomy or proctocolectomy is associated with shorter hospital length of stay, less post-operative complications, and improved readmission outcomes.
