However, pancreatic resection is technically a demanding procedure and whereas mortality after a pancreaticoduodenectomy is currently < 3%-5% in experienced high-volume centers, post-operative morbidity is considerable, about 30%-50%. At present, the single most significant cause of morbidity and mortality after pancreatectomy is the development of pancreatic leakage and fistula (PF). The occurrence of a PF increases the length of hospital stay and the cost of treatment, requires additional investigations and procedures, and can result in life-threatening complications. There is no universally accepted definition of PF that would allow standardized reporting and proper comparison of outcomes between different centers. However, early recognition of a PF and prompt institution of appropriate treatment is critical to the prevention of potentially devastating consequences. The present article, reviews the evolution of post resection pancreatic fistula as a concept, and discusses evolving definitions, the current preventive strategies and the management of this problem.展开更多

He was successfully treated with antibiotics and percutaneous transhepatic gallbladder drainage, but returned to the hospital two days after discharge with a rare complication of this technique, biliopleural fistula. A thoracostomy tube was inserted to drain the pleural effusion, and the patient’s previous antibiotics reinstated. After two weeks of drainage and antibiotics, the fistula healed spontaneously without the need for further intervention.展开更多

We describe an unusual case of aortic aneurysm and rupture which occurred after retroperitoneal aortoduodenal fistula formation as a rare complication caused by biliary metallic stent-related duodenal perforation. To our knowledge, this is the first report describing a lethal complication of a bleeding, aortoduodenal fistula and caused by biliary metallic stent-induced perforation.展开更多

A case of a 50-year-old multiparous female who developed suddenly portal hypertension due to SAVF formation is presented. The patient suffered from repeated episodes of haematemesis and melaena during the past twelve days and thus was emergently admitted to hospital for management. Clinical and laboratory investigations established the diagnosis of portal hypertension in the absence of liver parenchymal disease. Endoscopy revealed multiple esophageal bleeding varices. Abdominal computed tomography （CT） and transfemoral celiac arteriography documented the presence of a tortuous and aneurysmatic splenic artery and premature filling of an enlarged splenic vein, findings highly suggestive of an SAVF. The aforementioned vascular abnormality was successfully treated with percutaneous transcatheter embolization. Neither recurrence nor other complications were observed.展开更多

However, dislocation of the PEG-tube into the duodenum can lead to serious complications. An 86-year old Japanese woman with PEG-tube feeding sometimes vomited after her family doctor replaced the PEG-tube without radiologic confirmation. At her hospitalization, she complained of severe tenderness at the epigastric region and the PEG-tube was drawn into the stomach. Imaging studies showed that the tip of PEG-tube with the infl ated balloon was migrated into the second portion of the duodenum, suggesting that it might have obstructed the bile and pancreatic ducts, inducing cholangitis and pancreatitis. After the PEG- tube was replaced at the appropriate position, vomiting and abdominal tenderness improved dramatically and laboratory studies became normal immediately. Our case suggests that it is important to secure PEG-tube at the level of skin, especially after replacement.展开更多

A case of esophagotracheal fistula secondary to esophagitis 9 years after esophagectomy and gastric pull-up for treatment of esophageal carcinoma is described.

Potential complications of RFA include liver abscess, ascites, pleural effusion, skin burn, hypoxemia, pneumothorax, subcapsular hematoma, hemoperitoneum, liver failure, tumour seeding, biliary lesions. Here we describe for the first time a case of biliary gastric fistula occurred in a 66-year old man with a Child＇s class A alcoholic liver cirrhosis as a complication of RFA of a large hepatocellular carcinoma lesion in the nl segment. In the light of this case, RFA with injection of saline between the liver and adjacent gastrointestinal tract, as well as laparoscopic RFA, ethanol injection （PEI）, or other techniques such as chemoembolization, appear to be more indicated than percutaneous RFA for large lesions close to the gastrointestinal tract.展开更多

We report here two cases of intraductal papillary mucinous carcinoma （IPMC） with atypical manifestations. In one case, we discussed a pseudomyxoma peritonei caused by a ruptured IPMC. In the other case we discussed the fistulization of IPMC into the stomach and duodenum. These two cases suggest that IPMN can either spontaneously rupture causing mucinous materials to spill into the free abdominal cavity or directly invade adjacent organs resulting in fistula development.展开更多
