Prediction of surgical management for operated adhesive postoperative small bowel obstruction in a pediatric population.

Abdominal surgery might contribute to postoperative intraperitoneal adhesions, with a high rate of recurrence. In the present study, we aimed to analyze potential factors for the surgical intervention of operated adhesive postoperative small bowel obstruction (SBO) in pediatric patients and compare the outcomes of patients managed by conservative treatment or surgical operation for an episode of SBO.From January 2007 to January 2017, the records of 712 patients admitted with SBO to Children's Hospital, Chongqing Medical University, were reviewed retrospectively. The patients were divided according to surgical intervention or conservative management. Potential predictors for surgical intervention were investigated, including the initial operation data and the current clinical variables. A Cox regression model was used to determine the independent risk factors of surgical intervention. A systematic follow-up for recurrence was performed based on surgical intervention or conservative management.Among the 712 patients admitted with SBO, 266 patients were managed surgically and 446 patients were managed conservatively. In the multivariate analysis, the predictors for the surgical intervention included initial surgical features, such as elevated markers of inflammation (WBC, CRP), incision location (HR, 2.31; 95CI, 1.29-5.26; P = .031), and emergency procedure (HR, 1.46; 95%CI, 1.13-3.42; P = .014), and current variables, such as crampy pain (HR, 4.66; 95%CI, 1.69-9.48; P < .001), ascites (HR, 5.43; 95%CI, 1.84-13.76; P < .001) and complete small bowel obstruction (HR, 3.21; 95%CI, 1.45-8.74; P < .001). The median follow-up time (interquartile range) was 3.6 years (range, 1 month-8 years) for the entire study population. Twenty-one patients (9.2%) who had undergone surgical intervention were rehospitalized for a new SBO episode, as were 53 patients (14.9%) who had been managed conservatively (P = .028; OR, 1.72, 95% CI, 1.00-2.95).Operated adhesive postoperative SBO with the following characteristics should heighten vigilance for surgical intervention: an initial emergency procedure with midline incisions and the current strangulation status. New hospitalizations were lower after surgical management than conservative treatment.
