Biliary–enteric fistulas: report of five cases and review of the literature

Internal biliary fistulas (IBF) are seen rarely. Because the symptoms and signs of IBF are not specific and the diagnosis is not suspected, these patients are commonly investigated with plain abdominal films (PAF), ultrasonography (US), upper gastrointestinal series (UGIS), barium enema (BE), and computed tomography (CT), but not always with endoscopic retrograde cholangiopancreatography (ERCP). The purposes of this article are (a) to attract attention of radiologists to presumptive findings of IBF, so as not to misdiagnose this unsuspected and rare disease, and (b) review of the literature while presenting radiologic features of our cases. Five cases of IBFs in which extrahepatic biliary tree communicating with duodenum (four cases) and colon (one case) are reported. Diagnostic work-up of cases were done by PAF, US, UGIS, BE, and CT. Aerobilia, which cannot be explained using other means, ectopic gallstone and small bowel dilatation, nonvisualization of the gallbladder despite no history of cholecystectomy, and thick-walled shrunken gallbladder adherent to neighboring organs were suggestive findings of IBF in our study. Knowledge of imaging findings suggestive of IBF and a high index of suspicion increase the diagnostic rate of IBFs.

Narrowing the embryologic window of the adriamycin-induced fetal rat model of esophageal atresia and tracheoesophageal fistula

We recently reported on a new fetal rat model of esophageal atresia (EA) with tracheoesophageal fistula (TEF) induced by prenatal exposure to adriamycin (1.75 mg/kg i. p. injected daily to the pregnant dam from the 6th to 9th gestational days). With this treatment regime, many fetuses were resorbed and the number of associated malformations was very high. The present study demonstrates that similar doses of the drug administered only on the 8th and 9th gestational days allow higher fetal survival (9.7 3.9 vs. 6.8 4.7 fetuses per litter, P < 0.01) with a similar incidence of EA-TEF (41.2% vs. 56.4%, n. s.) and decreased occurence of associated anorectal and genitourinary malformations. Since this model is an instrument for further investigation of the disturbed cellular and morphogenetic events leading to EA and TEF, the narrowing of the embryologic window obtained by the present study will allow better focusing of the research on the critical period of time involved.     

Completely covered cloacal exstrophy: recognition of a new clinical sub-entity

A case showing many of the typical visceral features of cloacal exstrophy is reported. The patient had fn imperforate anus, a cecal-cloacal fistula, dehiscence of the pubiic symphysis, and lumbosacral spina bifida with synsingomyelia, but the lower abdominal wall was intact without any visceral extroversion. The pertinent literature was reviewed, and it was found that this case corresponded to t typical case of completely covered cloacal exstrophy. Only six cases, including the present one, have so far been reported in the literature. From a clinical viewpoint, it apparently occupies an intermediate position in the wide spectrum of cloacal anomalies between classical cloacal exstrophy and imperforate anus with recto-cloacal fistula, but anatomatically and embryologically it is definitely a variant of cloacal exstrophy. In other words, it looks like an imperforate anus with recto-cloacal exstrophy, but should be treated as a variant of loacal exstrophy. The anatomy, classification, embryology, diagnosis, and management of this peculiar surgical condition are discussed, and recognition of this entity is urged.     

全喉切除术后早期经口进食的临床观察

目的 :对喉癌、梨状窝癌行全喉切除术后早期经口进食进行可行性研究。方法 :42例行全喉切除术的患者 (其中喉癌 34例 ,梨状窝癌 8例 )随机分为两组 :观察组 2 1例 ,术后 48～ 72h经口进食 ;对照组 2 1例 ,按常规 10～ 12d经口进食。结果 :观察组咽瘘发生率为 4.8%(1/ 2 1) ,对照组为 9.5 %(2 / 2 1) ,两者差异无显著性意义(P >0 .0 5 ) ;观察组术后平均住院天数较对照组明显缩短。结论 :术前未行放疗的喉癌、梨状窝癌患者行全喉切除术后 48～ 72h经口进食是安全可行的。

Successful Embolization of Coronary Arteriovenous Fistula Using an Interlocking Detachable Coil

Although the efficacy and feasibility of coil embolization of coronary arteriovenous fistulas have been reported, the procedure may be complicated by migration of the coil into peripheral vessels or pulmonary arteries. We report two cases of successful coil embolization of such lesions using an interlocking detachable coil. This system can provide safer and more effective coil embolization in patients with coronary arteriovenous fistula.     

The use of magnetic resonance imaging in the assessment of malignant vaginal fistulas

The objective of this study was to determine whether magnetic resonance imaging (MRI) could reliably demonstrate fistulas and any associated mass and to see whether these findings were beneficial in the management of the fistula. Twelve consecutive patients presenting with suspected vaginal fistulas were examined prospectively with MRI, using a combination of sequences, for the presence, extent and configuration of fistulas and any associated mass. Comparison was made with CT when available. All patients underwent examination under anesthesia (EUA) and the findings compared. Of the 12 women presenting, seven had vesico-vaginal fistulas (VVF) and seven had recto-vaginal fistulas (RVF). Four women had both types of fistulas. The underlying pathology was cervical cancer (seven cases), colonic cancer (three cases), breast cancer (one case) and ovarian cancer (one case). Vaginal fistulas were unequivocally seen on MRI in eight of 10 cases with fistulas. In the two cases with a difference between the MRI and EUA findings, the MRI was interpreted as showing more than was found at EUA. In the seven women with VVF, MRI detected five of the cases. In the seven women with RVF, MRI detected all seven cases. Magnetic resonance imaging was correct in determining the presence of recurrent disease in the pelvis when an associated mass was seen (seven cases). Computer-assisted tomography was compared in 10 cases and in six cases, the results were comparable and in four cases, more information was obtained from the MRI. Magnetic resonance imaging appears to be accurate in detecting and defining complex gynecologic fistulas and should be considered the investigation of choice to aid the planning of restorative, salvage or palliative surgery.     

Tracheoesophageal fistula: New option in management

Tracheoesophageal fistula is a life threatening condition. Patients not managed surgically ultimately die of their disease. Surgical management is the treatment of choice. We present a case of a patient that developed a tracheoesophageal fistula after tracheostomy. Surgical repair was done which failed due to infection. The patient was managed with the help of an esophageal stent and Trichloroacetic Acid cautery. This approach can be used in selected patients, depending upon the size and site of TEE Larger fistulae and those situated lower down e.g. supra carinal cannot be managed by this technique.
