Background  Small bowel obstruction (SBO) is a common postoperative complication of ulcerative colitis (UC). There have been a few recent reports of afferent limb syndrome (ALS) as a rare occurrence in cases of SBO. We present a case of ALS with recurrent SBO that was successfully managed surgically.    Case presentation  When this male patient was 55 years old, he underwent laparoscopy-assisted anus-preserving total proctocolectomy, the creation of a J-type ileal pouch, ileal pouch-anal canal anastomosis (IPAA), and creation of ileostomy for intractable UC. Three months later, ileostomy closure was performed. The first onset of SBO was observed 5 months after ileostomy closure. SBO occurred repeatedly, and the patient was hospitalized nine times in approximately 2 years. Each SBO was improved by non-surgical treatment. A computed tomography (CT) scan revealed that the afferent limb was narrowing and twisted, and gastrografin enema confirmed narrowing at the proximal portion of the pouch inlet. Endoscopy showed a sharp angulation at the pouch inlet. We suspected ALS and decided on a surgical policy and performed pouchopexy and ileopexy to the retroperitoneum by suturing with excision of the remaining blind end of the ileum. Endoscopy 3 days after surgery showed neither twist nor stricture in the fixed ileal pouch or the afferent limb. At the time of writing, the patient remains free of SBO symptoms.    Conclusion  Clinicians should consider ALS when examining a patient with recurrent intermittent SBO after IPAA surgery. When ALS is suspected, the patient is indicated for surgery such as surgical pexy.
