Postoperative small bowel obstruction in infants and children

Area of Science:

• Pediatric Surgery
• Gastrointestinal Surgery

Background:

• Small bowel obstruction (SBO) is a significant complication following abdominal surgery in children.
• Adhesive SBO is a common cause of readmission and reoperation in pediatric surgical patients.

Purpose of the Study:

• To investigate the incidence, timing, risk factors, and outcomes of postoperative small bowel obstruction (SBO) in pediatric patients who underwent laparotomy.
• To identify factors associated with the development of adhesive SBO and its impact on patient mortality.

Main Methods:

• Retrospective review of 1476 laparotomies performed on pediatric patients between 1970 and 1980.
• Analysis of cases complicated by postoperative small bowel obstruction (SBO) requiring reoperation.
• Evaluation of risk factors including prior surgical procedures, peritonitis, and time to SBO development.

Main Results:

• 33 out of 1476 patients (2.2%) developed postoperative small bowel obstruction (SBO).
• 80% of SBO cases occurred within three months of the initial surgery.
• Increased risk of adhesive SBO was associated with multiple prior peritoneal procedures and pre-existing peritonitis.
• A single adhesion was the cause of obstruction in over 70% of cases, with circulatory disturbances noted even with early reintervention.
• The overall mortality rate for SBO was 6%.

Conclusions:

• Postoperative small bowel obstruction (SBO) is a notable complication in pediatric laparotomies, with adhesions being the primary cause.
• Risk factors for SBO include prior abdominal surgeries and peritonitis, emphasizing the importance of meticulous surgical technique.
• Early recognition and intervention are crucial, though mortality remains a concern, highlighting the need for continued research and improved management strategies.
