Conventional radiographic procedures are not helpful in the preoperative documentation of gangrenous cholecystitis or gallbladder perforation. Three cases in which preoperative diagnosis was accomplished by endoscopic retrograde cholangiography are described. Gangrene was identified in all three by a shaggy outline of the gallbladder wall with amorphous debris and stones in the lumen. Perforation was identified in two of the cases by extravasation of contrast material into a pericholecystic abscess. This information, as well as the status of the common duct, was important to the surgeon.
传统的放射学检查方法对坏疽性胆囊炎或胆囊穿孔的术前诊断并无帮助。本文描述了3例通过内镜逆行胆管造影术完成术前诊断的病例。在所有3例中，均通过胆囊壁参差不齐的轮廓以及管腔内的无定形碎片和结石确定存在坏疽。在其中2例中，通过对比剂外渗至胆囊周围脓肿而确定存在穿孔。这些信息以及胆总管的情况对外科医生而言至关重要。
