Postoperative intussusception after surgery for malrotation and appendicectomy in a newborn

Operative treatment for intussusception: Should an incidental appendectomy be performed?

BACKGROUND/OBJECTIVES

An incidental appendectomy is performed by some surgeons during operative treatment for intussusception to eliminate future appendicitis as a diagnostic consideration. However, an appendectomy can increase the risk of infection and other noninfectious complications making an incidental appendectomy controversial. We examined outcomes for surgical intervention for intussusception with appendectomy (SWA) compared to surgical reduction alone (SRA).

METHODS

The Pediatric Health Information System database, 8/2008-9/2015, was retrospectively analyzed for patients under the age of five who required an operative intervention for intussusception without bowel resection. Demographic data and postoperative outcomes were analyzed. Available data included need for postoperative enema, subsequent small bowel obstruction, recurrent intussusception, length of stay (LOS), and adjusted total cost (ATC).

RESULTS

Fifty-seven percent (748/1312) of patients had appendectomy performed during surgical reduction, 564 (43%) did not. ATC ($10,594 vs. $8939, p < 0.001) and LOS (3.0 vs. 2.48, p < 0.001) are higher in the SWA group. Rates of readmission are similar, but post-operative small bowel obstruction may be higher in the SWA group (1.3% vs. 0.35%, p = 0.06).

CONCLUSION

There is a higher mean LOS and ATC in the SWA group. This study suggests that appendectomy during surgery for uncomplicated intussusception should be reconsidered and requires further investigation.

Postoperative intussusceptions in children and infants: a systematic review

BACKGROUND

Postoperative intussusception (POI) is an unusual complication in children and infants who underwent various kinds of surgery. The early recognition was difficult for its rarity and atypical presentations. This study evaluates the clinical features of POI through a literature review.

METHODS

MEDLINE database was searched for relevant articles that reported the children and infants with POI since 1990 in English-language using the key word "postoperative intussusception". All published studies containing clinical data for POI in children and infants were included. Reference lists of retrieved articles were reviewed for additional cases. Detailed data of the included cases were extracted and analyzed.

RESULTS

Twenty-six studies with total 127 cases of POI were included. According to the extracted data, the median age was 19 months with the male-to-female ratio 1.5:1. There were 65 operations (51.2 %) that involved gastrointestinal system, 26 cases (20.5 %) of retroperitoneal tumor resection, 12 operations (9.4 %) involved diaphragm, 8 operations (6.3 %) involved urinary system, 5 cases (3.9 %) of partial pancreatectomy, 11 cases (8.7 %) of non-abdominal operations. 75.5 % presented symptoms in the first 7 days after surgery. The prominent symptom was bilious vomiting or increased nasogastric output (87.1 % of 101 patients), following abdominal distention (74.3 %), abdominal pain (35.6 %). Six cases (5.0 %) of ileocolic POI were reduced successfully by air enema. The small bowel intussusception attributed 85.6 % of POI (95 patients). Laparotomy and manual reduction were performed in 104 cases (86.0 %). Nine patients (7.4 %) underwent intestinal resection and anastomosis.

CONCLUSIONS

POI should be suspected in pediatric surgical patients who showed signs of intestinal obstruction in the early postoperative period. Early recognition and prompt management are important.

Postoperative intussusception in infants and children: a report of seven cases

Postoperative intussusception is an uncommon but serious condition in infants and children. Here, we report seven cases of postoperative intussusception in infants and children who were seen at our institution over the last 13 y. The patients showed increased nasogastric drainage, vomiting, lack of stool, and/or growing abdominal distension 2 to 9 d following abdominal surgery. Manual reduction was successful in five cases. In two cases, necrosis was found and intestinal resection and anastomosis were carried out. No recurrence was observed at six months of follow-up. Postoperative intussusception should be suspected in pediatric surgical patients who showed signs of intestinal obstruction in the early postoperative period.

Colocolic intussusception in a preterm infant with intestinal malrotation

The association of intussusception and intestinal malrotation is referred to as Waugh syndrome. A prospective study among 49 children with intussusception found a 40% incidence of malrotation. We describe the rare occurrence of colocolic intussusception in a neonate with malrotated intestine. We believe this is the first reported case in the neonatal period where the pathogenic lead point was an intestinal lymphangioma.

Waugh's syndrome: report of two cases

The association of intussusception and intestinal malrotation has been reported rarely in the literature. This association is called Waugh's syndrome. The authors report 2 cases of Waugh's syndrome and discuss diagnostic features and treatment methods.
