[Acute pancreatitis may cause pancreaticopleural fistula]. / Akut pankreatitis kan medføre fistel til pleura.

Pancreaticopleural fistula is a condition in which pancreatitic enzymes drain into the pleural cavity. It is a complication of pancreatic disease and usually presents with thoracic rather than abdominal symptoms. Although unusual, it should be included in the differential diagnosis to substantial and persistent unilateral pleural effusion. We report the case of a 71-year-old man who presented with dyspnoea. During two months, the patient underwent pulmonary evaluation before the pancreas was identified as the site of primary pathology. The key to the diagnosis was an elevated level of pleural fluid amylase.

[Late perforation following laparoscopic gastric bypass]. / Sen perforation af tyndtarm efter laparoskopisk gastrisk bypass.

We present two cases in which the patients were admitted to a local hospital with acute abdominal pain four or five months after having undergone laparoscopic gastric bypass. In both cases, operation revealed a perforation of the small bowel close to the distal anastomosis. In the first case, a massive constipation of the small bowel was most likely a contributing factor. In the second case, the cause was a kink of the entero-entero anastomosis leading to obstruction and finally perforation of the biliary limp. Late perforations are among the rarely reported complications associated with gastric bypass but as our two cases illustrate they are important to keep in mind.

[False aneurysm of the hepatic artery after laparoscopic cholecystectomy: a rare but potentially fatal complication]. / Pseudoaneurisme efter laparoskopisk kolecystektomi: en sjaelden, men alvorlig komplikation.

Pseudoaneurysm is an uncommon complication of laparoscopic cholecystectomy, potentially fatal due to the high risk of bleeding. The diagnosis requires Doppler UL and CT. The optimal treatment is coil embolization. We report a case where a 35 year-old woman presented with a false aneurysm of the right hepatic artery two weeks after an uncomplicated laparoscopic cholecystectomy and was successfully treated with coil embolization.

[Bowel ischaemia treated with stent placement]. / Tarmiskaemi behandlet med stentanlaeggelse.

This is a case report of a younger woman admitted to hospital with abdominal pain and weight loss. Four weeks after admittance, she was diagnosed with severe bowel ischaemia at laparotomy. Arteriography showed occlusive disease in the mesenteric arteries, which were treated with a stent. The entire intestine was preserved, apart from 10 cm of jejunum due to bowel perforation. The diagnosis of polyarteritis nodosa was confirmed based on biopsy and clinical symptoms.
