CaseNecrotizing enterocolitis (NEC) caused by Clostridium butyricum is common in neonates; however, a case of NEC in adults has not been previously reported. An 84‐year‐old Japanese man developed C. butyricum‐related NEC during hospitalization for treatment of stab wounds to the left side of the neck and lower abdomen, without organ damage, and concomitant pneumonia.OutcomeThe patient developed acute onset of emesis accompanied by shock during his admission; partial resection of the small intestine was carried out due to necrosis. Pathologic findings showed mucosal necrosis and extensive vacuolation with gram‐positive rods in the necrotic small intestine. Blood culture tests revealed C. butyricum infection. The patient's condition improved after the surgery. He was moved to a rehabilitation hospital on day 66.ConclusionThis study suggests that hospitalized adult patients who receive antibiotic treatment are at risk for NEC.

Transumbilical laparoscopy-assisted appendectomy performed by residents is feasible and safe. It is an acceptable as a part of routine surgical training.

Surgical treatment of mesenteric injuries is necessary to control hemorrhage, manage bowel injuries, and evaluate bowel perfusion. It has recently been suggested that some patients can be managed with transcatheter arterial embolization (TAE) for initial hemostasis. We present a hemodynamically unstable patient who was initially managed by TAE for traumatic mesenteric hemorrhage. A 60-year-old man was injured in a motor vehicle accident and transported to our facility. On arrival, the patient was hemodynamically stable, and had abdominal pain. Physical examination revealed a seatbelt sign on the lower abdomen. A contrast-enhanced computed tomography (CT) scan showed intra-abdominal hemorrhage, mesenteric hematoma, and a giant-pseudoaneurysm, but no intra-abdominal free air or changes in the appearance of the bowel wall. After the CT scan, his vital signs deteriorated and surgical intervention was considered, but TAE was performed to control the hemorrhage. After TAE, the patient was hemodynamically stable and had no abdominal tenderness. A follow-up CT scan was performed 2 days later which showed partial necrosis of the transverse colon and some free air. Resection of the injured transverse colon with primary anastomosis was performed. The patient improved and was discharged 35 days after injury. TAE can be effective as the initial hemostatic procedure in patients with traumatic mesenteric hemorrhage.
