Treatment of iatrogenic biliary obstruction by balloon dilatation of a biliary jejunal fistula

Biliary obstruction and multiple hepatic abscesses occurred in a patient after ligation of a segmental branch of the right hepatic duct. The patient was successfully managed by transhepatic biliary drainage and balloon dilatation of an internal fistula that developed between the ligated duct and a Roux limb of jejunum. Internal biliary fistulas may be dilated using interventioanl radiologic techniques to permit nonobstructed bile flow. Implications for the nonsurgical treatment' of biliary strictures are discussed.

Closure of a large bronchial fistula with a latissimus dorsi myocutaneous flap

We describe a case of a large bronchial fistula and empyema after right upper lobectomy that was treated successfully with open window thoracostomy followed by a latissimus dorsi myocutaneous flap and limited thoracoplasty. A latissimus dorsi myocutaneous flap can provide immediate airtight closure of a large bronchial fistula, allowing lavage and curettage of the empyema cavity to reduce the chance of postoperative infection. An important aspect of this technique is that the deepithelialized skin side rather than muscle is sutured to an opening of the bronchus. As compared with other techniques, a latissimus dorsi myocutaneous flap is superior in that it requires a single incision and does not require an intraop-erative change of position. In addition, the technique causes little dysfunction of the chest and shoulder and preserves the vascular supply to ensure the viability of the flap even if it was divided in a previous operation.     

Long-term results of surgically treated traumatic rectourethral fistulas

OBJECTIVE: Rectourethral fistulas are uncommon, usually iatrogenic injuries that are demanding to treat. We present the challenging problems involving the treatment of rectourethral fistulas caused by war wounds. MATERIALS AND METHODS: In the period 1991-1996, during the war in Croatia and Bosnia, six patients with rectourethral fistulas caused by war injuries were operated in our institution by the same surgeon. All patients were young males with a mean age of 24.6 years. In all patients, double diversion (diversion colostomy and cystostomy) was performed at the time of the injury in military hospitals. In three patients, multiple unsuccessful operations were performed in other institutions to close rectourethral fistula. We found urethrocystography and proctoscopy as the most reliable diagnostic studies and performed them in all patients. In first three patients, we performed transanal repair with anterior rectal wall advancement flap. Because it failed in all three patients, we performed York-Mason trans-sphincteric approach and anterior rectal wall advancement flap after which rectourethral fistula closed in all patients. Because of the satisfactory results, we performed the same procedure in other three patients. RESULTS: In all patients rectourethral fistula healed 2 months after the operation. Closure of diverting colostomy was performed after urethrocystography and proctoscopy proved that the rectourethral fistula has healed. There were no operative deaths and no major complications. Urethral stenosis developed in one patient and was successfully managed by dilatation. CONCLUSION: We believe that York-Mason trans-sphincteric approach offers straightforward access through healthy tissues and good fistula visualization. Anterior rectal wall advancement flap can easily be performed and offer good chances for definitive closure of the rectourethral fistula.     

血管内栓塞外伤性颈动脉海绵窦瘘126例随访结果

目的探讨血管内栓塞治疗外伤性颈动脉海绵窦瘘（TCCF）的近期及远期效果。方法139例TCCF患者行血管内栓塞术后3个月开始通过再次入院、邮寄调查表或电话随访．其中再次入院完成及收回调查表共64例，电话随访62例，获随访126例（90．6％）。结果126例中26例术后行MRA检查，20例行颅脑CT检查，均未见异常；10例术后半年行DSA复查，未见复发。11例复发，经再次栓塞后治愈。结论血管内栓塞治疗TCCF，术后复发率不高，临床随访即可。     

腹泻型、便秘型肠易激综合征和功能性便秘患者的直肠肛管测压比较

目的研究腹泻型、便秘型IBS和功能性便秘患者直肠肛管测压参数的不同，并评价性别和年龄对各项参数的影响，方法腹泻型IBS(n=18)、便秘型IBS(n=14)、功能性便秘(n=30)和健康对照组(n=18)，通过定点牵拉法进行直肠肛管测压。结果腹泻型IBS、便秘型IBS、功能性便秘以及健康对照组直肠肛管测压各项压力参数基本无差异，但三组患者的诱发RAIR所需的最小气体容量均显著高于健康对照组，便秘型IBS和功能性便秘模拟排便时发生矛盾运动的百分比显著高于腹泻型IBS和健康对照组；便秘型IBS和功能性便秘组中，肛管上部和下部最大紧缩压力，以及模拟排便发生矛盾运动的百分比男性均高于女性；腹泻型IBS组内男性模拟排便发生矛盾运动的百分比高于女性；健康对照组内男性肛管下部静息压力和最大紧缩压力高于女性；各组20-50岁人群和50-80岁人群的各项压力参数无显著性差异，但功能性便秘组青年组诱发RAIR所需的最小气体容量低于老年组。结论腹泻型IBS、便秘型IBS和功能性便秘患者的直肠肛管测压各项压力参数无助于这三型功能性肠病的鉴别诊断。男性的直肠肛管测压的多项压力参数显著高于女性，男性更易出现模拟排便矛盾运动，年龄对直肠肛管测压各项参数无明显影响。     

不同营养支持方式对肠外瘘患者人体组成改善作用之比较

目的观察不同营养支持方式对肠外瘘患者人体组成的改善作用。方法30例肠外瘘患者分成两组各15例,分别给予全肠外营养支持(TPN)或全肠内营养支持(TEN),观察10d前后患者人体组成及血清胰岛素样生长因子-1(IGF-1)的变化。结果10d后所有患者的体重指数(BMI)与体细胞群(BCM)显著改善,而TEN组患者10d前后BCM增加幅度更明显,分别为(27.5±0.8)kg和(29.0±0.6)kg,Day10与Day0相比,P<0.01。两组患者总体水(TBW)与细胞内水(ICW)均增加,尤其ICW,Day10与Day0相比,TEN组P<0.01;TPN组P<0.05。血清IGF-1在两组患者治疗后均有显著上升,TEN组增加幅度更明显,Day0为(175.0±32.9)ng/ml,Day10为(255.5±34.1)ng/ml,与Day0比较,P<0.01;与TPN组比较,P<0.05。IGF-1的变化与BCM的改善显著正相关(r2=0.16,P<0.05)。结论营养支持治疗能显著改善肠外瘘患者的体细胞群,纠正细胞内、外水的异常分布,而EN作用更明显。
