CT findings of GP included gas accumulation under the recess of xiphoid,gas accumulation in the area of lesser omentum,gas accumulation under the recess of peritoneal cavity,and seroperitoneum. Conclusion As a non-invasive examination means for abdomen,CT examination can discover whether there is dissociative gas or not and estimate the amount of gas in abdomen more rapidly and exactly.CT can also estimate the position of perforation elementarily.The recess under xiphoid is the first place where the dissociative gas assembles after gastrointestinal perforation.

材料与方法1 一般资料：1999年7月至2 0 0 4年1月我院经CT检查的胃肠穿孔的患者13例，其中男8例，女5例；年龄19～6 5岁，平均4 0 2岁。13例均行腹部CT平扫及站立位腹部X线平片检查，其中6例先行CT检查后行X线检查。8例既往有胃、十二指肠溃疡病史，2例有明显腹部外伤史。10例表现为突发上腹部疼痛、腹肌紧张，1例表现为明显右下腹部疼

Objective:To summarize the clinical experience of laparoscopic gastroduodenal ulcer perforation repair in gastroduodenal ulcer perforation.

CT images of the 6 UAs showed homogenous and low density in comparison with muscles. Of the 6 UAs, 2 (33%) were lobulate, 4 (67%) were regularly round or oval; 1 (17%) had bone septa, 2 (33%) had root resorption of the neighboring teeth, 3 (50%) had cortical perforation. All UAs showed well-circumscribed margins without soft tissue masses. Three UAs were examined by enhanced studies and showed mild to moderate enhancement of the wall. Of the 5 MAs, 3 (60%) showed low to intermediate density as compared with muscles, 2 (40%) showed homogenous and intermediate density; 3 (60%) had bone septa; 3 (60%) showed root resorption or destruction of the neighboring teeth. All 5 MAs were lobulate with cortical perforation, soft tissue masses, and ill-defined margins. All 3 MA5 examined by enhanced studies showed strong enhancement. CONCLUSIONS: SMAs are usually seen in middle-aged patients.

UA病变平扫时与肌肉相比内部都呈均匀低密度，其中4例(67%)呈较规整的圆形或椭圆形，2例(33%)呈分叶状，3例(50%)局部骨皮质有缺损，但未见软组织肿块形成，l例(17%)见不全骨性分隔，2例(33%)邻近牙根有吸收，行增强扫描的3例囊壁均呈轻中度的强化。5例MA的病灶都呈分叶状，且骨皮质均被穿破并有软组织肿块形成，边界不清，其中3例(60%)平扫时与肌肉相比呈等低混杂密度，2例(40%)呈较均匀等密度，3例(60%)可见不全的骨性分隔，3例(60%)见牙根的吸收或破坏，行增强扫描的3例都呈明显强化。

The operation of appendicitis perforation with diffuse peritonitis by McBurney incisions had the merit of little scar, secluding, slight pain, fast recovery and fewer incidence rate of pulmonary infection, incisions infectious, incisional hernia, as long as master, So, the operation of treatment appendicitis perforation with diffuse peritonitis by McBurney was much better than by righ middle abdomen paramedian incisions.
