病例:男,31岁。无意中发现右下腹部有一包块,自觉无不适。体检:右下腹部可触及一拳头大小包块,质硬,表面光滑,边界清楚,较固定,无压痛。钡剂灌肠和乙状镜检查均提示肠道通畅和来自右下方盲肠外压迫。B超检查示右下腹有9.2×7.7×7.5cm的肿物,并有多个液化灶。准备就绪后,在硬膜外麻醉下行包块切除术。术中见肿瘤位于右腹膜后,卵圆形,大小与B超所示相符。包膜完整,灰白色,质硬而脆。上下两极各有一线绳样“瘤蒂”贯穿基底,直径约0.3～0.4cm,粗细均匀一致,外有包膜。周围分离干净后将两极瘤蒂钳夹切断,肿瘤完整取出。切断蒂部时手术感觉较硬,有丝状纤维,无明显出血。肉眼观为灰白色束
Case: Male, 31 years old. Inadvertently found a mass in the right lower abdomen, consciously no discomfort. Physical examination: The right lower abdomen can touch a fist mass, hard, smooth surface, clear boundary, relatively fixed, no tenderness. Both barium enema and sigmoidoscopy revealed intestinal patency and external cecum pressure from the lower right. B-ultrasound showed a 9.2 x 7.7 x 7.5 cm mass in the right lower quadrant and multiple liquefaction foci. When ready, block resection is performed under epidural anesthesia. During surgery, the tumor was located in the right peritoneum, oval, and the size was consistent with that shown in B ultrasound. The capsule is complete, gray, hard and brittle. The upper and lower poles have a string-like “stomach pedicle” that runs through the base and has a diameter of about 0.3-0.4 cm. The thickness is uniform and there is an outer envelope. The bipolar tumor clamps were cut off and the tumors were completely removed. When the pedicle was cut off, the surgical sensation was hard, there was filiform fiber, and there was no obvious bleeding. The naked eye is gray
