Treatment of acute pancreatic pseudocysts (APP) after an episode of severe acute pancreatitis (SAP) remains controversial. Both population heterogeneity and limited numbers of patients in most series prevent a proper analysis of therapeutic results. The study design is a case series of a large, tertiary referral hospital in the surgical treatment of patients with APP after SAP. An institutional treatment algorithm was used to triage patients with complicated APP and organ failure based on Sequential Organ Failure Assessment scores to temporizing percutaneous or endoscopic drainage to control sepsis and improve their clinical condition before definitive surgical management. Over a 10-year period of study (December 1995 to 2005), 73 patients with APP after an episode of SAP were treated, 43 patients (59%) developed complications (infection 74.4%, perforation 21%, and bleeding 4.6%) and qualified for our treatment algorithm. Percutaneous/endoscopic drainage was successful in controlling sepsis in 11 of 13 patients (85%) with severe organ failure and allowed all patients to undergo definitive surgical management. The morbidity (7 vs 44.1%, P = 0.005) and mortality rates (0 vs 19%, P = 0.04) were significantly higher in complicated vs uncomplicated APP. Acute pancreatic pseudocysts after SAP are unpredictable and have a high incidence of complications. Once complications develop, there is a significantly higher morbidity and mortality rate. In complicated APP with severe organ failure, percutaneous/endoscopic drainage is useful in controlling sepsis and allowing definitive surgical management.

Objectives: The aim of this study was to analyze the incidence, risk factors, and clinical outcomes of pancreatic pseudocyst after acute or acute-on-chronic pancreatitis. Methods: We retrospectively reviewed the medical records of 350 patients with acute pancreatitis and 55 patients with acute-on-chronic pancreatitis. Results: Pancreatic pseudocyst developed in 14.6% of acute pancreatitis and in 41.8% of acute-on-chronic pancreatitis (P=0.00). In the acute-on-chronic pancreatitis group, interval from symptom onset to hospital visit was longer, and the incidence of recurrent pancreatitis and alcoholic etiology was higher than that of the acute pancreatitis group (P < 0.01). There was no significant difference in the spontaneous resolution rate between both groups. Of the total 68 conservatively treated patients with pseudocyst, the pseudocyst decreased in size or disappeared in 77.9% and showed no change in 1.5%. The risk factors of pseudocyst were the presence of underlying chronic pancreatitis, the interval from symptom onset to visiting the hospital, and an alcoholic etiology. The factor-predicted spontaneous resolution was a single lesion. Conclusions: Pseudocyst developed more frequently in patients with acute-on-chronic pancreatitis, and most pseudocysts improved spontaneously irrespective of underlying chronic pancreatitis. A longer period of a "wait-and-see" policy for more than 6 weeks is suggested for asymptomatic pseudocyst, especially for a single lesion.

Acute pancreatitis comprises a range of diseases. Clinical manifestations range from mild symptoms to a life-threatening or life-ending process. Operative management is focused on managing the acute complications, the long-term sequelae, or the prevention of recurrent pancreatitis. Using the least amount of intervention is the goal. However, the evolution of videoscopic and endoscopic techniques have greatly expanded the tools available. This article provides a review of the three major categories of operations: ameliorating the emergent problems associated with the inflammatory state, ameliorating chronic sequelae, and prevention of a subsequent episode.

Pancreatic pseudocysts (PPs) are defined as fluid collections more than 4 weeks old that are surrounded by a nonepithelial wall of fibrous or granulation tissue. Many risk factors have been associated with pseudocyst development but predictive factors remain to be explored. The aim of this study was to investigate the clinical, and biochemical parameters that may predict the development of a PPs after an attack of acute pancreatitis (AP).

The location of a pseudocyst (PC) in the liver is an exceptional event, and intrahepatic PCs are mainly located in the left lobe. We report here a case of right intrahepatic PC following acute pancreatitis associated with cystic (aberrant pancreatic) dystrophy of the duodenal wall (CDDW) and chronic pancreatitis. Morphological assessment (ultrasound, computed tomography [CT] scan, and cholangio-magnetic resonance imaging [MRI]) revealed a 10-cm right intrahepatic collection and rupture of the main pancreatic duct. Percutaneous puncture permitted us to detect a high level of amylase in the collection, confirming the diagnosis of intrahepatic PC. Surgical drainage concomitant with pancreatico-duodenectomy for the treatment of CDDW resulted in disappearance of the collection. The mechanism involved in this patient was rupture of the pancreatic duct in the retroperitoneal cavity and erosion reaching the right hepatic parenchyma. Although intrahepatic PCs are rare, the diagnosis of intrahepatic PC complicating acute pancreatitis can be confirmed by a high level of amylase in the collection. Asymptomatic intrahepatic PCs can be treated conservatively, and symptomatic intrahepatic PCs can be managed either transcutaneously or surgically.

A 53-year-old male visited his primary physician for epigastric and back pain. Abdominal-enhanced computed tomography (CT) revealed a simple cyst of the pancreatic tail attached to the stomach. A distal main pancreatic duct (MPD) was clearly dilated, but no pancreatic tumor was identified around the stenosis of MPD by CT scan and magnetic resonance cholangiopancreatography (MRCP). Endoscopic retrograde pancreatography (ERP) revealed stenosis and distal dilation of the MPD located between the body and tail of the pancreas. Endoscopic ultrasound (EUS) revealed a low density mass of 7?mm in size with distal dilation of the MPD. With the suspicion of a small pancreatic cancer, the patient underwent distal pancreatectomy and splenectomy with lymph node dissection (D2). On histopathological evaluation, a small pancreatic adenocarcinoma of 6?mm in size was detected around the stenosis of MPD. Final pathological diagnosis was moderately differentiated invasive ductal adenocarcinoma of the pancreas with no lymph node metastasis (Japan Pancreatic Society (JPS) classification 7th edition; Pbt, TS1 (6?mm), tub2, intermediate type, INF β, ly1, v1, ne1, mpd(-), pT1b, pN0, pM0, stage IA,PCM(-), DCM(-) and the Union International Control Cancer (UICC) classification of malignant tumors 6th edition; pT1, pN0, pM0, stage IA, R0). We herein reported a patient who underwent radical resection for T1 pancreatic adenocarcinoma of 6?mm in diameter which caused acute pancreatitis and a pseudocyst due to obstruction of the MPD.

Purpose of review: To review advances over the last year in the prevention, diagnosis and management of acute pancreatitis. Recent findings: Obesity is an independent risk factor for severity in acute pancreatitis, and heavy alcohol consumption for the development of necrosis in severe acute pancreatitis. Biochemical markers have been further tested, including carbohydrate-deficient transferrin for the diagnosis of alcohol-induced acute pancreatitis, urinary trypsinogen-2 as a diagnostic marker for acute pancreatitis, and interleukin-4 and procalcitonin as markers of disease severity. A new, simple stratification system, the 'panc 3 score', has been described. There are conflicting data on the use of antibiotic prophylaxis in acute necrotizing pancreatitis, and on the chemoprevention of postendoscopic retrograde cholangiopancreatography pancreatitis. Enteral feeding is established as standard practice early in the management of acute pancreatitis of all aetiologies; probiotics and other compounds may also play a role. Summary: Over the last year, there have been further innovations in the risk stratification and management of acute pancreatitis. Unresolved issues include chemoprevention of endoscopic retrograde cholangiopancreatography-induced acute pancreatitis, the indications for antibiotic prophylaxis in severe acute pancreatitis and nutritional supplementation with probiotics and synbiotics.

Colonic fistula is rare after acute pancreatitis but is associated with a high mortality. In the current study, we describe a case of colonic fistula in a 39-year-old woman secondary to severe acute pancreatitis. Abdominal CT showed the presence of pancreatic pseudocysts. After percutaneous drainage was performance, yellow feculent liquid fluided from the drainage tubes. Subsequently, fistulography via drainage tube showed the presence of a colonic fistula into the descending colon. She was successfully treated by a colectomy for colonic fistula and drainage of the pancreatic pseudocysts. Although Colonic fistula is an infrequent complication of pancreatitis, clinicians should be aware of it because of its high mortality.
