1/176. Primary aorto-duodenal fistula secondary to infected abdominal aortic aneurysms: the role of local debridement and extra-anatomic bypass.

    Gastrointestinal bleeding secondary to spontaneous rupture of an infected abdominal aortic aneurysm into the duodenum is a rare and highly lethal clinical occurrence, representing roughly a third of all primary aortoduodenal fistulas. diagnosis is problematic due to the subtleties in the clinical presentation and course, and surgical treatment is usually delayed, representing a challenge even for the experienced vascular surgeon. The overall mortality is over 30% and the operative approaches are still controversial. Two cases of ruptured infrarenal aortic aneurysms complicated with aortoduodenal fistula were recently treated at our institution. Bacterial aortitis was documented by arterial wall cultures positive for klebsiella and salmonella species respectively. The clinical courses and outcomes of the two patients (one survivor ) treated with retroperitoneal debridement and extra-anatomic bypass and a review of the modern surgical treatment are herein described.

2/176. Gastroduodenal intussusception secondary to a gastric carcinoma.

    A case of gastroduodenal intussusception secondary to transpyloric prolapse of a primary gastric carcinoma is reported. Both the condition itself and the leading tumor, gastric carcinoma, are extremely exceptional. A diagnosis of this rare entity was established pre-operatively by endoscopy that demonstrated spontaneous reduction of the intussusception. This may be the first documentation of spontaneous reduction of the gastroduodenal intussusception during endoscopy.

3/176. Enterolith: an unusual cause of afferent loop obstruction.

    Most cases of enterolith have been reported in association with the diverticula of small bowel. We report here a case of a patient in whom a huge enterolith developed in the afferent loop of Billroth II anastomosis with ensuing obturation obstruction. The enterolith was clearly shown on the preoperative abdominal computed tomograph and was removed through a duodenotomy. The postulated mechanism of the enterolith formation is impaired duodenal evacuatory motor activity due to previous gastrectomy.

4/176. Small-bowel investigation in occult gastrointestinal bleeding.

    Obscure gastrointestinal bleeding after careful endoscopy of the upper and lower gastrointestinal tract is predominantly of small-bowel origin. patients presenting with overt blood loss account for a select subpopulation of those with small-bowel bleeding. Although relatively rare, these patients often require repeated blood transfusions, investigation, and hospitalization before a diagnosis is reached. These events have a considerable negative impact on the patient's quality of life. Standard evaluation using enteroclysis, tagged red cell studies, and angiography are proven to be of limited value in this context. Push enteroscopy has significant advantages in this patient group, with the ability to deliver endoscopic therapy. Sonde enteroscopy is now reserved for a few patients to guide decisions on surgery, particularly in those with significant medical comorbidity. Definitive evaluation may require perioperative enteroscopy, but many patients can be managed without the need for surgery. A team approach by physician, radiologist, and surgeon following locally agreed algorithms is essential for the successful management of this challenging clinical problem.

5/176. Tuberculous infection of the descending thoracic and abdominal aorta: case report and literature review.

    We report here a case of infrarenal aortic disruption and aortoduodenal fistula secondary to tuberculous aortitis in a 77-year-old man. From a review of experience with operative management of tuberculous infection of the descending thoracic and abdominal aorta reported in the English-language literature, including the current report, we found that operative repair was attempted in 26 patients with tuberculous aortitis of the abdominal (n = 16), thoracic (n = 8), and thoracoabdominal (n = 2) aorta. Six patients had emergent operations for massive hemoptysis (n = 2), aortoduodenal fistula (n = 2), or abdominal rupture (n = 2), with an associated 30-day mortality of 50%. Elective or semi-elective repair was undertaken in 20 patients, of whom 19 (95%) survived for at least 30 days. On the basis of limited experience with this rare entity, in situ graft replacement is an appropriate treatment of tuberculous aneurysms and pseudoaneurysms of the descending thoracic and abdominal aorta.

6/176. gallbladder carcinoma with choledochoduodenal fistula: a case report with surgical treatment.

    A 79 year-old man was admitted to our hospital because of upper abdominal pain and nausea. A mobile tumor was palpable in the right upper abdomen. Abdominal ultrasonography, computed tomography and celiac angiography revealed a gallbladder tumor. Endoscopic retrograde cholangiopancreatography revealed a fistula 1.5 cm oral to the orifice of the papilla of Vater, dilatation of the common bile duct, and a filling defect in the gallbladder. Pancreatoduodenectomy associated with reconstruction using Imanaga's method was performed under a pre-operative diagnosis of gallbladder carcinoma with choledochoduodenal fistula. The gallbladder contained a tumor and two bilirubin stones impacted in the orifice of the duodenal papilla. Histological studies confirmed that the gallbladder tumor was a mucinous adenocarcinoma and had not infiltrated the bile duct. We speculated that choledochoduodenal fistula stimulated the development of cancer due to chronic irritation from pancreatic juice reflux.

7/176. Duodenal duplication cyst manifested by duodeno-jejunal intussusception and hyperbilirubinemia.

    A rare case of duodenal duplication cyst containing stones in a 17-year-old patient is presented. The cyst, acting as a leading point for duodeno-jejunal intussusception caused proximal small bowel obstruction and hyperbilirubinemia. Preoperative diagnosis was based on abdominal computerized tomography. At operation, the cyst wall was unroofed creating free drainage into the duodenal lumen without damaging the biliary and pancreatic ducts with resolution of symptoms.

8/176. A case of bilioduodenal fistula treated with a self-expandable metallic stent.

    We report the case of a 72 year-old female patient who suffered from biliary fistulae. The biliobiliary and bilioduodenal fistulae appeared after an operation for biliary bleeding. Conventional therapy for biliary fistula would be the disconnection of the fistula by either conservative or operative treatment. In the present case, however, it was preferable to enlarge the fistula to drain bile juice into the duodenum, rather than to close the fistula because it would have been difficult to achieve a tight adhesion with this operation. The enlargement by a plastic tube stent failed to drain the bile juice into the duodenum, because the sludge made the tube stenotic. Therefore, a self-expandable metallic stent was applied in this case. An expandable stent was used because a large final caliber is necessary to prevent stenosis of the fistula by sludge and mucosal hyperplasia. After insertion of a self-expandable metallic stent by the percutaneous transhepatic biliary drainage route, the patient has not suffered from cholestasis and cholangitis for the last 30 months. It can therefore be concluded that enlargement of the fistula by a self-expandable metallic stent is a convenient therapy for such biliointestinal fistulae.

9/176. Primary aortoduodenal fistula treated successfully with surgery in a patient with Takayasu's arteritis.

    Takayasu's arteritis was originally described as a systemic inflammatory arterial disease presenting with occlusive changes. However, it has also been known to cause aneurysm formation. In this report, a patient with Takayasu's arteritis was found to have an aortoduodenal fistula. An emergency operation was carried out with resection of the saccular aneurysm and the fistula. The aorta was reconstructed with a prosthetic graft and the duodenum repaired. A pedicled omental flap was placed between the aorta and the duodenum. The postoperative recovery was uneventful, there was no evidence of persistent bleeding, and the patient was well at the 3-year follow-up. This is the first case in the English language literature of a primary aortoduodenal fistula treated successfully with surgery in a patient with Takayasu's arteritis.

10/176. Primary hypertrophic tuberculosis of the pyloroduodenal area: report of 2 cases.

    tuberculosis of the stomach and duodenum is rare in patients with pulmonary tuberculosis. Primary involvement is even rarer. Two cases of primary tuberculosis of the localised to the pyloro-duodenal area are presented. The most common symptoms are non-specific leading to a difficulty in establishing a pre-operative diagnosis. A high degree of suspicion is therefore required for its diagnosis and to differentiate it from more frequent causes of gastric outlet obstruction such as chronic peptic ulcer disease and gastric carcinoma. The treatment of gastric tuberculosis is primarily medical with anti-tuberculous drug therapy. The role of surgery lies in the cases with obstruction following hypertrophic tuberculosis. The surgery done is usually a gastroenterostomy. With the relative rate of extra-pulmonary tuberculosis increasing, tuberculosis of the pyloro-duodenal area should be considered in the differential diagnosis of gastric outlet obstruction.
