Introduction: Situs inversus totalis (SIT) is an uncommon clinical manifestation. Patients with SIT typically have malformation in the thorax and abdomen. The incidence of SIT ranges from 1/10,000 to 1/20,000 (Al-Jumaily and Hoche. J Laparoendosc Adv Surg Tech A 2001;11:229). Jejunojejunal intussusception is a rare complication after Roux-en-Y gastric bypass. Intussusception in adult cases accounts for 5% of adult intestinal obstruction cases, while in children, the occurrence is high and the majority of them are idiopathic cases.
Case report: Here, we present an uncommon case of jejunojejunal intussusception after Roux-en-Y gastric bypass in an SIT patient. We performed reduction at the beginning and resection was done finally.
Discussion: We explore the potential causes and discuss the diagnosis and therapy.
Conclusion: Intussusception in an SIT patient is an uncommon case. The symptoms are vague, and it is difficult to diagnose. Clinicians should be vigilant postoperatively, especially when abdominal pain after gastrointestinal surgery occurs. It is a rare case worth learning.
