腹腔镜乙状结肠癌伴降结肠系膜旋转不良一例报道

Laparoscopic sigmoid colon carcinoma with persistent descending mesocolon:a case report

降结肠系膜旋转不良(PDM)是由降结肠与腹膜后融合不全引起的,PDM通常无症状。然而,降结肠系膜旋转不良、乙状结肠向右侧与回盲部的先天粘连以及肠系膜下动脉的解剖变异等均可能会对结直肠癌的手术决策及难易度产生影响。我们报道一例乙状结肠癌伴肝转移瘤合并PDM的诊治,对其腹腔镜手术治疗的体会及注意要点加以阐述。

Persistent descending mesocolon(PDM)is caused by the incomplete fusion of the descending colon and retroperitoneum.It is usually asymptomatic.However,persistent descending mesocolon,congenital adhesion of the right sigmoid colon to the ileocecal region,and anatomical variation of the inferior mesenteric artery may affect surgical decision-making and difficulty level in colorectal cancer.We report the diagnosis and treatment of a case of sigmoid colon cancer with liver metastasis combined with PDM,and describe the experience and points for attention of the laparoscopic surgery.
