Abstract:
Omental torsion represents a rare cause of acute abdomen，current literatures predominantly limited to case reports focusing on greater omentum torsion，by contrast，lesser omentum torsion is exceedingly uncommon. One case of male patient aged 8 years and 7 months with epigastric pain was admitted to the Children's Hospital of Zhejiang University School of Medicine. Initial abdominal ultrasound suggested omental pathology. To confirm the diagnosis，repeat ultrasonography and contrast-enhanced CT were performed，leading to a preliminary suspicion of greater omentum torsion. Following multidisciplinary collaborative consultation，surgical intervention was recommended. The patient underwent laparoscopic omentectomy with adhesiolysis，which intraoperatively confirmed lesser omentum torsion. Histopathological examination provided definitive diagnostic confirmation.Postoperative abdominal ultrasound revealed no significant abnormalities. This case underscored the critical value of dynamic multimodal imaging evaluation and multidisciplinary decision-making in the preoperative diagnosis and therapeutic management of lesser omentum torsion，aiming to establish ultrasonographic diagnostic references for lesser omentum torsion while simultaneously heightening clinical vigilance toward rare diseases.
