Adult-onset congenital intestinal malrotation: A case report and literature review.

Abstract

Intestinal malrotation is an infrequent congenital anomaly primarily observed in neonates, and adult-onset cases are exceedingly rare. Studies on adult congenital intestinal malrotation are limited. A case with congenital intestinal malrotation is reported in our study. The clinical data were collected and the treatment process and effect were evaluated. A 45-year-old female who had been experiencing vomiting for over 40 years was admitted to our hospital. According to the result of CT scan, intestinal volvulus accompanied by bowel obstruction was suspected. Then laparoscopic examination was applied to the patient and was ultimately diagnosed with adult congenital intestinal malrotation. We performed Ladd's procedure combined with gastrojejunostomy and Braun anastomosis. The patient recovered well and was successfully discharged from the hospital on the 13th day after surgery. After a 6-month follow-up, the symptom of vomiting was significantly alleviated and body weight was gained for 10 kg. She was very satisfied with the treatment. Adult congenital intestinal malrotation is a rare disease that is often misdiagnosed owing to nonspecific clinical manifestations. Therefore, awareness about this condition should be enhanced. Surgery remains the cornerstone of treatment for this disease. Combining gastrojejunostomy and Braun anastomosis with the traditional Ladd procedure can optimize surgical outcomes.
