目的:评价螺旋CT对胆囊-十二指肠内瘘伴胆石性肠梗阻的诊断价值。方法:对8例经手术证实为胆囊-十二指肠内瘘伴胆石性肠梗阻的螺旋CT表现及重建技术进行回顾性分析。结果:8例患者中,2例胆石位于十二指肠降段;2例位于空肠;1例位于空回肠交界处;另外3例位于回肠内。胆石短径为(4.70±1.20)cm,长径为(6.09±1.90)cm。胆囊-十二指肠内瘘伴胆石性肠梗阻的CT直接征象主要有瘘口的显示以及胆石位于梗阻段肠腔内;间接征象主要有胆囊及胆道积气;胆囊塌陷及胆囊与十二指肠分界模糊、结构紊乱;肠梗阻。以上两种直接征象若同时存在即可作出诊断,如一种直接征象同时伴有两种或两种以上间接征象亦可作出诊断。结论:胆囊-十二指肠内瘘伴胆石性肠梗阻具有典型的CT表现,螺旋CT能够对其作出明确诊断。 相似文献

残余胆囊的超声诊断 总被引:1,自引:1,他引:0
杜春仙 《中国医学影像学杂志》2000,8(5):385-385
残余胆囊系指胆囊切除术后 ,因胆囊颈残留或胆囊残株过长所形成的“小胆囊”。由于病变未能根除或残余胆囊并发炎症 ,结石甚至肿瘤 ,导致术后症状依旧或复发。因此 ,残余胆囊已成为一个不可忽视的问题。本文分析总结了我院 1993 10~1999 10经手术和病理证实的 16例残余胆囊病例资料 ,旨在探讨残余胆囊的诊断及其漏诊原因分析。1 资料与方法1 1 本组病例男 6例 ,女 10例 ,年龄 2 4~ 6 6岁。首次胆囊手术后出现临床症状的时间不等 ,4例术后症状依然存在 ,10例从数月至数年才出现症状。其临床表现为 :右上腹痛 ,腹胀 ,恶心、呕吐等 ,少数患… 相似文献

目的:探讨MSCT对胆囊十二指肠内瘘的诊断价值。方法:回顾性分析7例胆囊十二指肠内瘘的资料,7例均行MSCT检查,使用ADW 4.5后处理工作站对图像行MPR,分析其特征性影像学表现。结果:7例MSCT直接征象:4例瘘口位于十二指肠球部,3例位于降部;瘘口内径3~19 mm,平均8 mm。间接征象:胆囊形态萎陷、壁增厚(胆囊壁厚5~10 mm,平均8 mm);胆囊十二指肠局部黏合,轮廓模糊;均有胆道系统积气;胆囊结石异位致机械性肠梗阻(5例梗阻位于十二指肠,2例梗阻位于空肠上段)。结论:MSCT不仅可清晰分辨胆囊与十二指肠间瘘口,还可观察胆囊形态、胆肠粘连、胆系积气、胆石性肠梗阻,对指导临床治疗具有重要价值。 相似文献

Cholecystocolonic fistula: serial CT imaging features 总被引:1,自引:0,他引:1
We report the CT imaging findings of an unusual case of cholecystocolonic fistula, which had presented in the emergency department with melena. It is rare for the fistulous communication to occur between gallbladder and the colon. We describe the serial imaging findings, which were diagnostic of this condition. 相似文献

We encountered a case of hepatic hilar cholangiocarcinoma resulting in cholecystoduodenal fistula after insertion of self-expandable
metallic biliary stents (EMBSs). To our knowledge, there has been no report of cholecystoduodenal fistula after insertion
of EMBSs. This case suggests that immediate gallbladder decompression may be necessary if acute cholecystitis occurs after
insertion of EMBSs. 相似文献

Roux-en-Y choledochojejunostomy is a common biliary reconstruction procedure.The collection of gallstones in the jejunal limb is a rare complication.Here we present a case of a 61-year-old Chinese female who received Roux-en-Y choledochojejunostomy 10 years ago.Diagnosis of recurrent bile duct stones accompanying infection was made before operation.She also had an abdominal mass which was possibly an intussuscepted colon or a huge fecolith.At laparotomy,an oval stone(5 cm in diameter) and 3 smaller multifaceted stones(2 cm in diameter) were found in the jejunal limb.A fistula between this jejunum and colon was also found.Although the typical manifestations of diarrhea were present,the diagnosis of a biliary colonic fistula was missed before operation.Partial colectomy was performed with the fistulous opening repaired.A T-tube was left in the jejunal limb and the mesocolon aperture was enlarged and revised.Her postoperative convalescence was uneventful.We report this case hoping to sharpen our diagnostic acumen. 相似文献

The most common etiology of arteriovenous fistulae (AVF) in the lower extremity is iatrogenic, usually from diagnostic or
therapeutic angiographic procedures. The finding of a palpable groin thrill, early venous opacification on contrast-enhanced
abdominal-pelvic CT, and typical findings on duplex ultrasonography establish the diagnosis. Anatomic confirmation is then
made by arteriography. A case of an incidentally discovered AVF in patient presenting to the Emergency Department is presented.
Radiographic findings concerning and subsequent management of this patient are then discussed.

Congenital H-type and recurrent tracheo-esophageal fistulas (TEF) are always difficult to diagnose. For a more accurate diagnosis
we designed a new double balloon catheter, which is a modification of esophageal dilatation balloon. The catheter has two
balloons to occlude the esophagus proximal and distal to the fistula. The fistula can be identified by passing of the contrast
material to the tracheal tree, which was injected into the esophageal segment between the inflated balloons. To prove the
efficiency of this catheter, a TEF was created surgically in a New Zealand rabbit. On the postoperative fourteenth day the
catheter was tried and the fistula could be visualized easily by injecting the contrast material. We think this technique
may be of use in the diagnosis of TEF in children.

Arteriovenous fistula (AVF) is a rare, late complication of lumbar disc surgery. It is often not suspected and the symptoms
are diagnosed as heart failure or deep venous thrombosis. We report a case in which the patient developed leg swelling and
high-output congestive heart failure due to a left ilioiliac AVF after lumbar laminectomy.
