Primary bacterial peritonitis and catheter-associated infections compose the large majority of abdominal events in continuous ambulatory peritoneal dialysis (CAPD) patients. Yet occasionally primary pathology involving the abdominal viscera develops, and surgery is frequently considered. The early manifestations of intraabdominal inflammation or bleeding in patients undergoing CAPD depend on the pathological process, its access to the peritoneal cavity, and whether generalized bacterial peritonitis supervenes to obscure helpful physical findings. Clear dialysate is not a reliable sign that major pathology is absent, nor does initial stabilization of the clinical course with antibiotic therapy uniformly indicate that surgery will not be necessary. Polymicrobial peritonitis may develop in cholecystitis, pancreatitis, or from a colonic source, the latter featuring more bacterial species and more gram-negative and anaerobic organisms. A history directed at progression of symptoms and sites of abdominal discomfort and an examination for deep local tenderness and bowel incarcerated in an abdominal wall hernia are essential. Measurement of dialysate amylase and Gram stain of dialysate for food fibers may be helpful. Imaging techniques such as abdominal radiographs for dilated bowel or free subdiaphragmatic air, ultrasonography of the gallbladder or pancreas, computed tomographic (CT) scanning of the lower abdomen, and water-soluble contrast colonic studies may help identify the pathologic process. Special studies such as these should be considered early in the course of suspected unusual abdominal events in patients on CAPD.

BACKGROUND: Although unusual, but not rare, obstruction in the vicinity of the jejunojejunostomy in Roux-Y gastric bypass (RYGBP) can progress in a very short period of time to a life-threatening situation. METHODS: Over a 10-year period in 1,174 RYGBPs, we have seen seven instances of acute and subacute partial to complete small bowel obstructions in the vicinity of the jejunojejunostomy, which can lead to acute gastric dilatation due to obstruction of the bilio-pancreatic limb. Signs and symptoms of the obstruction may include tachycardia, oliguria, hypotension, severe epigastric pain with or without a palpable mass in the epigastrium, chronic bile regurgitation and bilious vomiting, and a possible increase in serum amylase. Laboratory data otherwise has not been helpful, and although a palpable abdominal mass may be diagnostic, the best tools have been radiologic, i.e. the acute abdomen series, limited upper GI series in the patients that appear to be only partially obstructed, abdominal ultrasound and probably most importantly, CT of the abdomen. RESULTS: In the seven cases presented, diagnoses included internal hernia, adhesions, an idiopathic spontaneous hematoma of the bowel wall and retrograde intussusception at the jejunojejunostomy. CONCLUSIONS: Since many surgeons who perform bariatric surgery are alone in their community, they should train their non-bariatric surgical colleagues and associates to be aware of these potential deadly problems.

A 55-year-old man presented to the emergency department with a 12-hour history of severe crampy abdominal pain, nausea, vomiting and obstipation. The patient had a complex medical history, including coronary artery disease, lupus, hypothyroidism, epilepsy, pancreatitis and renal calculi. However, the patient had no history of a hernia or abdominal surgery. Physical examination revealed a temperature of 38.5 degrees C and a soft distended abdomen that was diffusely tender without signs of peritonitis. The rest of the physical examination was unremarkable. Routine laboratory investigations including a complete blood cell count, electrolytes, liver enzymes and amylase were normal, with the exception of a decreased hemoglobin level of 116 g/L. We ordered a plain abdominal radiograph (Fig. 1) and a contrast-enhanced computed tomography (CT) scan of his abdomen. What is your diagnosis?

Acute pancreatitis and afferent loop syndrome (ALS) have similar symptoms and physical findings. Accurate early diagnosis is essential, as the management of acute pancreatitis is predominantly conservative whereas ALS usually requires surgery. We experienced one case of pancreatitis due to ALS with internal hernia. Laboratory findings of patient showed elevated serum amylase, lipase and WBC count. One day after admission, diagnosis was modified as acute pancreatitis caused by ALS on computed tomography. Patient was managed with surgical treatment and operation finding revealed ALS due to internal hernia. He was recovered well after surgical treatment and discharged without significant sequelae.

A 41-year-old man with a medical history of chronic back pain, seizure disorder, alcohol and tobacco abuse presented with acute shortness of breath. Chest X-ray showed a large right-sided pleural effusion. Pleural fluid analysis was significant for an elevated amylase level, suggestive of pleural effusion secondary to pancreatitis. Magnetic resonance cholangiopancreatography (MRCP) revealed a persistent right-sided pleural effusion in connection with a right pararenal space fluid collection via a Bochdalek hernia. An endoscopic ultrasound found hyperechoic strands and foci, and pancreatic parenchyma consistent with chronic pancreatitis, as well as a pseudocyst in the pancreatic head. A chest tube was ultimately placed to continuously drain the pleural effusion. The patient was discharged and was referred to gastroenterology for outpatient follow-up. This case illustrates a rare presentation of chronic pancreatitis with a Bochdalek hernia as a right-sided pleural effusion in a patient who was previously asymptomatic.
