A 40 year old man with no co morbidities presents with diffuse abdominal pain and distention and a 2 day history of nausea and vomiting. He is afebrile and hemodynamically normal, but is anuric and serum creatinine is 3.0 mg/dl. A CT scan confirms necrotizing pancreatitis with a large peripancreatic phlegmon. There is no evidence of cholelithiasis or cholecystitis. He has had no prior episodes of pancreatitis. The next step in management should be A. Total parenteral nutrition (TPN) B. Bowel rest, fluid resuscitation C. Surgical pancreatic debridement D. Fine needle aspiration of peripancreatic fluid E. Prophylactic antifungal agents
A 39 year old woman is admitted with gallstone pancreatitis and epigastric pain. Pertinent data include amylase, 2000 U/L; bilirubin, 1.2 mg/dl; and WBC count 15,000. After 2 days of medical management, her epigastric pain resolves. Her amylase is 340 U/L and her bilirubin and WBC count have normalized. Laparoscopic cholecystectomy should be attempted A. After ERCP and sphincterotomy B. Prior to discharge C. Once her amylase is normal D. 4 6 weeks later to allow for a cooling down period E. Only if the patient develops recurrent pancreatitis
A 35 year old male is admitted with acute pancreatitis secondary to hypertriglyceridemia. Oral intake is discontinued, and he is hydrated with IV fluids. He has minimal upper abdominal tenderness. 72 hours after admission, he has worsening leukocytosis and elevated amylase with RUQ rebound tenderness. The CT scan shown is obtained. The most appropriate management would be A. Laparotomy B. Nasogastric tube decompression and broad spectrum antibiotics C. Somatostatin therapy D. Repeat CT scan in 48 to 72 hours E. Percutaneous drainage.
A 35 year old male has epigastric pain and emesis. Four week previously, he was discharged after an admission for uncomplicated acute pancreatitis. He has been receiving corticosteroids since a renal transplant 4 years ago. Pertinent data include: WBC 11,000; amylase 1000; and normal creatinine. The CT scan shown is obtained. The most appropriate management is A. Open debridement B. Cystgastrostomy C. Roux en Y cystjejunostomy D. Enteral feeding distal to the ligament of Treitz E. CT guided percutanous drainage
Pseudocysts Develop in 5 10% of patients with acute pancreatitis and 50% of patients with chronic pancreatitis Suspect if patient does not recover with one week of medical therapy, or when symptoms return after period of improvement
Pseudocysts Acute fluid collection Irregular in shape Frequently resolve Debridement reserved for necrotizing pancreatitis with infection or abscess Follow with serial CT Treatment: expectant management Pseudocyst Require 6 12 weeks to mature Caused by disruption of pancreatic duct Usually seen in setting of chronic pancreatitis May cause obstruction of gastric outlet or biliary tree
Complications of Pseudocysts Obstruction Infection Pain Hemosuccus pancreaticus
Treatment of Pseudocysts Open Laparoscopic Endoscopic
A 42 year old previously healthy man arrives in the Emergency Department with a 12 hour history of excruciating epigastric pain. He is afebrile and not jaundiced. Pulse is 115/min, blood pressure 90/60, and WBC count is 16,400. The CT scan show is obtained. Immediate management should include A. Peritoneal dialysis B. Exploratory laparotomy C. Needle aspiration D. Fluid resuscitation E. ERCP
Four weeks later, the patient returns to the Emergency Department with abdominal fullness. Vital signs are normal. The CT scan show is obtained. Treatment now should be A. ERCP B. Surgical decompression C. Percutaneous aspiration D. 14 day course of antibiotics E. Repeat CT scan in 30 days
Treatment of pseudocysts MUST send biopsy of cyst wall to exclude malignancy
