Persistent descending mesocolon is a congenital anomaly in which the mesentery of the descending colon fails to fuse with the retroperitoneum, resulting in a mobile colon that is suspended by a mesentery extending from the left upper quadrant to the pelvic brim. This can predispose to intestinal obstruction by twisting of the colon, internal hernia with or without a mesenteric defect or intussusception. We present a case report of a 30-year-old male who presented with recurrent abdominal pain and distension, with a CT diagnosis of descending colonic volvulus due to persistent left mesocolon. The patient underwent a successful resection of the affected colon and had an uneventful recovery. This case highlights the importance of considering anatomical variants in the diagnosis and management of colonic volvulus.
永存降结肠系膜是一种先天性异常，其中降结肠系膜未能与腹膜后融合，导致结肠可移动，由从左上象限延伸至骨盆边缘的系膜悬吊。这可能因结肠扭转、伴有或不伴有肠系膜缺损的内疝或肠套叠而导致肠梗阻。我们报告一例30岁男性病例，该患者反复出现腹痛和腹胀，CT诊断为永存左结肠系膜导致的降结肠扭转。患者接受了受累结肠的成功切除，恢复顺利。该病例强调了在结肠扭转的诊断和治疗中考虑解剖变异的重要性。
