Abstract

Objective: The aim of this study was to review results of the treatment of patients with symptomatic
malrotation within a 25-year period at a single tertiary institute in Thailand.
Material and Method: A retrospective study of patients with malrotation of the intestine who were treated at
Queen Sirikit National Institute of Child Health between 1985 and 2009 was undertaken. Special attention was paid
to clinical presentations, radiologic findings and results of treatment. Patients who were found to have malrotation
as an incidental finding at laparotomy for other diseases were excluded from the study.
Results: A total of 153 patients underwent laparotomy for correction of symptomatic malrotation. Most of the
patients developed symptoms, mostly bilious vomiting, within 30 days after birth. Upper gastrointestinal series were
performed in 112 patients and revealed high gut obstruction, abnormal position of the duodenojejunal junction and
corkscrew sign in 97 (87%), 74 (60%), and 38 (34%) patients, respectively. Patients were divided into three groups
based on operative findings. Group A represented 58 patients, of whom 80% were neonates, who had only duodenal
obstruction due to Ladd’s band compression. Only one patient died postoperatively because of congestive heart
failure from congenital heart disease. Group B included 75 patients who had midgut volvulus without intestinal
necrosis. Approximately 70% of group B were neonates, and 3 died from complications of tetralogy of Fallot, severe
pneumonia and gastric perforation, respectively. Group C included the 20 remaining patients who developed midgut
volvulus with intestinal necrosis (involving 20% to 100% of the small intestine). Of these 20 patients, 17 (85%) were
neonates and 8 (40%) died from extensive (> 70%) bowel gangrene. Patients who survived extensive bowel resection
had the total length of viable small bowel over 30 cm. The mortality rate for all 153 patients was 7.8%.
Conclusion: Patients with malrotation developed symptoms within the neonatal period in approximately 80%
of the cases. About two-thirds of intestinal malrotations presented with midgut volvulus and 20% of these had bowel
gangrene. Necrosis over 70% of the small intestine was a significant risk factor for mortality in patients with midgut
volvulus.
