Transomental hernia (TOH) is an exceedingly rare subtype of internal hernia, often leading to acute small bowel obstruction with a high risk of ischemia. We present the case of a 58-year-old male with a history of laparoscopic inguinal hernia repair who developed abdominal pain, distension, vomiting, and obstipation. Contrast-enhanced computed tomography revealed clustered dilated ileal loops with a transition point suggestive of internal herniation. Exploratory laparotomy confirmed a TOH through the greater omentum without bowel ischemia. The defect was divided, and the postoperative course was uneventful. Due to its nonspecific presentation and diagnostic difficulty, TOH is frequently identified only at surgery. Prompt recognition and timely surgical management are essential to prevent serious complications.
经网膜疝（TOH）是一种极为罕见的内疝亚型，常导致急性小肠梗阻，且有很高的缺血风险。我们报告一例58岁男性病例，该患者有腹腔镜腹股沟疝修补术病史，出现腹痛、腹胀呕吐及便秘症状。增强计算机断层扫描显示回肠袢聚集扩张，有一个提示内疝的移行点。剖腹探查证实经大网膜发生了经网膜疝，无肠缺血情况。缺损处被分离，术后过程顺利。由于其表现不具特异性且诊断困难，经网膜疝常常仅在手术时才被发现。迅速识别并及时进行手术治疗对于预防严重并发症至关重要。
