ABSTRACT
OBJECTIVES: Autologous intestinal reconstructive (AIR) surgery is frequently utilized in the management of pediatric short bowel syndrome (SBS). However, little is known about the long-term sequela of these procedures. METHODS: We undertook a retrospective follow-up study addressing parenteral nutrition (PN) dependence, nutritional status, intestinal morbidity, and related complications in SBS patients having undergone AIR surgery (SBS-AIR, n = 19). We compared results with conservatively treated control SBS patients (SBS-C, n = 45). Eligible patients were identified from our institutional intestinal failure registry during 1985-2019. RESULTS: After median 11.4 follow-up years, 42% of SBS-AIR patients received PN in relation to 36% in SBS-C group ( P = 0.6210), and overall PN duration was significantly longer (35.4 vs 10 months, P = 0.0004) in SBS-AIR group. Although symptoms of intestinal dysfunction improved in majority (62%) of patients after AIR surgery, their symptoms remained more frequent and severe at latest follow-up compared to SBS-C group (39% vs 5%, P = 0.0015). Although bacterial overgrowth was more frequent in SBS-AIR group (53% vs 24%, P = 0.0416), latest endoscopy findings and fecal calprotectin levels as well as occurrence of anastomotic/staple line ulcerations were comparable between groups. Histological liver steatosis (50% vs 18%, P = 0.042) and impaired bone health (26% vs 6.7%, P = 0.042) were more frequent in SBS-AIR patients. CONCLUSIONS: While AIR surgery improved gastrointestinal symptoms and transition to enteral autonomy in majority of patients, a noteworthy proportion of them continued to suffer from clinically significant intestinal dysfunction and related complications. Close long-term follow-up of pediatric AIR surgery patients is mandatory.
