盆腔肿瘤,尤其是卵巢癌,容易早期播散到腹腔,除直接侵犯乙状结肠外,常累及横结肠。作者报告四例卵巢癌及一例乙状结肠癌患者,钡灌肠检查除发现有乙状结肠浸润、狭窄外,均显示横结肠下缘多发的结节状浸润、横结肠固定、成角。CT和/或超声检查可见腹水和大网膜板状增厚。作者指出,横结肠受累的途径是盆腔肿瘤经大网膜向上转移所致。三条结肠带在横结肠上的解剖 Pelvic tumors, especially ovarian cancer, are easily disseminated early to the abdominal cavity. In addition to direct violations of the sigmoid colon, they often involve the transverse colon. The authors reported that in four cases of ovarian cancer and one case of sigmoid colon cancer, barium enema examination in addition to the presence of sigmoid infiltration, stenosis, showed multiple nodular infiltration of the lower transverse colon, transverse colon fixation, angulation. CT and/or ultrasonography showed ascites and greater omental thickening. The authors pointed out that the way of transverse colon involvement is due to the upward migration of pelvic tumors through the omentum. Anatomy of three colon belts in the transverse colon
