A biliary fistula from the gallbladder can develop as a result of the erosion of stones into the surrounding viscera. An 82-year-old woman with multiple comorbid diseases presented with a persisting discharge from what was thought to be an abscess in the right hypochondrium, which had previously been drained. Sinogram confirmed fistulous communication with the gallbladder and gastric antrum. The fistulous tract was excised together with the gallbladder, and the gastric defect was repaired. The patient made an uneventful recovery.

Orocutaneous fistulas, or cutaneous sinuses of odontogenic origin, are uncommon but often misdiagnosed as skin lesions unrelated to dental origin by physicians. Accurate diagnosis and use of correct investigative modalities are important because orocutaneous fistulas are easily confused for skin or bone tumors, osteomyelitis, infected cysts, salivary gland fistulas, and other pathologies. The aim of this study is to present our experience with a patient with orocutaneous fistulas of odontogenic origin presenting as recurrent pyogenic granuloma of the cheek, and to discuss their successful treatment.

Biliary drainage in patients with malignant biliary obstruction relieves jaundice and prevents the development of cholangitis or hepatic failure from biliary obstruction. Therefore, this may result in better quality of life along with survival prolongation. Biliary stent placement is an effective and safe measure for biliary decompression and is preferred than bypass surgery in high risk patients. Entero-biliary perforation-communication is one of the rare complications of biliary stent. We herein report a case of duodeno-biliary perforation-communication in patient with distal cholangiocarcinoma who presented with duodenal ulcer and obstruction, occurring 4 years later from the metallic biliary stent insertion. Patient was managed with a pyloric metal stent and conservative care.

Renal angiomyolipoma (AML) is a common benign tumor in the urinary system, mainly composed of adipose tissue, blood vessels and muscle tissue. Renal AML is sporadic in most of patients, while a few are associated with tuberous sclerosis. Classical renal AML occurs predominantly in middle-aged females. Most cases are found incidentally during imaging examinations. The fat content makes AML have unique imaging characteristics and is easy to be identified with other renal tumors. However, the amount of fat varies in each tumor. AML that contains only microscopically detectable fat and whose amount of intratumoral fat may be too small to be identified on unenhanced computed tomography (CT) images is termed minimal fat or fat-poor renal AML, which appears as a high density shadow in the renal parenchyma on unenhanced CT images. Thus, it can be difficult to distinguish it from renal cell carcinoma (RCC) on imaging. Since the imaging findings are atypical, the diagnosis depends on pathological results. In addition, a few of AML can mimic malignant neoplasms. Recent studies suggested that AML might involve to peri-renal or renal sinus fat, regional lymphatics and other visceral organs, as well as inferior vena cava, which further makes the diagnosis more difficult. However, there is currently no reports about involvement of regional limphatics in minimal fat renal AML. In this article, we report a 27-year-old female patient without family history of tuberous sclerosis, who came to visit the hematologist because a high density shadow near the left kidney was found during CT scan which was accompanied by neck, armpits, groin, abdominal cavity and retroperitoneal lymph nodes enlargement. She was suspected of lymphoma in the beginning and transferred to Department of Urology to perform laparoscopic left renal mass and retroperitoneal lymph node excision and pathological examination for a definitive diagnosis. Finally, pathologic results revealed AML. Postoperative continuous lymphatic fistula developed and the retroperitoneal drainage of chylous fluid was 100-200 mL per day, lasting for 12 weeks. The fistula was successfully closed after conservative treatment including fasting and rehydration. This article summaries and discusses the diagnosis and treatment of renal AML with lymph nodes enlargement and the management of postoperative refractory lymphatic fistula by reviewing the related cases and literature.

A gastropericardial fistula, defined as penetration of a gastric lesion into the pericardium, is a rare occurrence. Such a fistula is usually associated with a huge ulcer in the gastric fundus, an ulcer within a hiatus hernia, a history of esophagogastric surgery, the concurrent use of non-steroidal anti-inflammatory drugs (NSAIDs), or Zollinger-Ellison syndrome. The patient in this case presented with shoulder pain and melena, caused by a gastropericardial fistula that had occurred as a late complication of postoperative esophagogastrostomy and a refractory gastric ulcer. Despite the severity of the condition, the patient showed great improvement after medical treatment and the fistula was cured at the end.

In Crohn's disease, neurologic complications such as cerebrovascular accident, headache, peripheral neuropathy have been reported sporadically. The pathogenesis of these neurologic complications is still unknown and controversial. We experienced a 22-year-old man, with Crohn's disease accompanied by optic neuritis. Loss of visual acuity was developed during the worsening course of enterocutaneous fistula. After high dose steroid treatment, his visual acuity and neurologic symptoms improved immediately.

PURPOSE: We investigated whether infantile vulvar abscesses are predictable features of rectovestibular fistula with a normal anus. MATERIALS AND METHODS: A retrospective analysis of five infants with vulvar abscesses and rectovestibular fistulae with normal anuses was performed. RESULTS: Four cases had a left vulvar abscess, and in one case the vulvar abscess was on the right side. All caregivers reported passage of stool from the vagina. The fistulae were almost uniformly located from the vestibule to the rectum above the anal dentate line, observable by visual inspection and probing under anesthesia. The first two cases were treated with division and closure of the fistulae after a diverting loop colostomy, and the remaining three cases with fistulotomy and curettage. There was no recurrence during the median follow-up period of 38 months. CONCLUSION: This unique rectovestibular fistula should be suspected in female infants with vulvar abscesses, especially when parents report passage of stool from the vagina. Fistulotomy and curettage may be an initial treatment and effective as a temporary diverting colostomy and delayed repair of the fistula.

The patient complained of finding on the right side of the neck fistula with discharge nine years. In recently, fistula spills significantly increased compared with the previous. Special physical examination: Right sternocleidomastoid middle 1/3 front border is seen here in a small fistula, translucence jelly secretion were spilling out when squeezeing the fistula, no smell. Ultrasound: On the right side of the upper cervical skin to submandibular gland rear could see tubular low echo area. MRI: Visible on the right side of the neck tube signal, after the submandibular gland rear. Three-dimensional CT: Visible on the right side of the neck by skin sinus crossings as deep as the tonsillar fossa lumen containing contrast agent. Clinical diagnosis: The second branchial cleft cyst and fistula.

We report the utility of contrast-enhanced magnetic resonance cholangiography (MRC) using gadoxetic acid (Gd-EOB-DTPA) in the diagnosis of bronchobiliary fistula associated with liver hydatid cyst. Contrast-enhanced MRC clearly delineated the leakage of contrast agent from the biliary duct and its communication with the bronchial tree. Providing functional information about physiologic or pathologic biliary flow in addition to the display of biliary anatomy, contrast-enhanced MRC stands as a robust technique in confidently detecting bronchobiliary fistula and bile leaks.
