Urine amylase levels are usually used to diagnose acute pancreatitis. However, there are reported cases where urine amylase levels are slightly increased in individuals without pancreatitis. Herein, we report the case of a young lady who presented with acute abdominal pain for 3 days. Her urine amylase level was 1717 U/L upon admission, and her condition was initially treated as acute pancreatitis. Unfortunately, the patient demonstrated abdominal guarding after 24 h; thus, urgent computed tomography (CT) was performed. CT revealed the presence of a dilated small bowel. She underwent emergency laparotomy, wherein a gangrenous small bowel with no evidence of saponification at the lesser sac was noted. Due to the non-specific nature of hyperamylasaemia, an alternative diagnosis other than acute pancreatitis should be considered if the clinical symptoms are not suggestive of pancreatitis or the condition worsens despite conservative management.

Background and Aim: Acute pancreatitis is one of the less frequently diagnosed lethal abdominal complications of cardiac surgery. The incidence of early postoperative period hyperamylasaemia was reported to be 30-70% of patients who underwent coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB). The mechanism of pancreatic enzyme elevation after cardiac surgery is not clear. Our aim was to determine the relationship between ischaemia associated temporary renal dysfunction and elevation of pancreatic enzymes after CABG.Methods: Forty-one consecutive patients undergoing CABG under CPB were prospectively studied to determine serum total amylase, phospholipase A2, macroamylase, Cystatin C and urine NAG levels.Results: Hyperamylasaemia was observed in 88% of the cases, with a distribution of 6% at the beginning of cardioplegic arrest, 5% at the 20th minute after cardioplegic arrest, 7% at the 40th minute after cardioplegic arrest, 14% when the heart was re-started, 26% at the 6th hour of intensive care and 30% at the 24th hour of intensive care. All of these patients had asymptomatic isolated hyperamylasaemia, and none of them presented with clinical pancreatitis. As indicators of renal damage; Cystatin C and NAG levels were higher compared to baseline values.Conclusion: Amylase began to rise during initial extracorporeal circulation and reached a maximum level postoperatively at 6 and 24hours. Decreased amylase excretion is the main reason for post CABG hyperamylasaemia. [ABSTRACT FROM AUTHOR]

Background and aims: Pancreatic abnormalities are common in inflammatory bowel disease (IBD) patients and represent a heterogeneous group of conditions that include acute pancreatitis, chronic pancreatitis, autoimmune pancreatitis and asymptomatic abnormalities. We sought to review the available evidence concerning the aetiology, clinical presentation, diagnosis and treatment of pancreatic conditions in IBD patients. Methods: A PubMed/Medline query was conducted addressing pancreatic disorders in IBD. Reference lists from studies selected were manually searched to identify further relevant reports. Relevant manuscripts about pancreatic disorders in patients with IBD were selected and reviewed. Results: Thiopurines and gallstones are the most frequent causes of acute pancreatitis in IBD patients. Thiopurine-induced acute pancreatitis is usually uncomplicated and self-limited. Some evidence suggests that chronic pancreatitis may be more common in IBD. Most cases are idiopathic, affecting young males and patients with ulcerative colitis. Autoimmune pancreatitis is a relatively newly recognized disease and is increasingly diagnosed in IBD, particularly for type 2 autoimmune pancreatitis in ulcerative colitis patients. Asymptomatic exocrine insufficiency, pancreatic duct abnormalities and hyperamylasaemia have been identified in up to 18% of IBD patients, although their clinical significance and relationship with IBD remain undefined. Conclusions: The wide spectrum of pancreatic manifestations in IBD is growing and may represent a challenge to the clinician. A collaborative approach with a pancreas specialist may be the most productive route to determine aetiology, guide additional diagnostic workup, illuminate the aetiology and define the treatment and follow-up of these patients.

Objective. There are no recommendations on how to proceed in patients with increased pancreatic enzyme activities but non-pancreatic diseases. The objective of this study was to investigate prospectively in a general medical hospital the incidence, causes and clinical impact of hyperamylasaemia and/or hyperlipasaemia in these patients. Material and methods. During a 4-month period in 2004, amylase and lipase activities were measured in all patients (n, 1765) admitted to the Department of Internal Medicine of the Municipal Clinic of Luneburg, Germany. Patients with increased enzyme activities underwent abdominal ultrasonography and, if inconclusive, other imaging procedures. Results. Amylase and/or lipase activities were increased in 140 (8%) patients with non-pancreatic diseases: amylase in 29 cases (21%) and 1 case (1%)<3 and>3 times the upper limit of normal, respectively, lipase in 120 cases (86%) and 6 cases (4%)<3 and>3 times, respectively. In 53 (38%) patients no further imaging studies could be performed. In the remaining 87 patients amylase was increased in 18 patients (21%) and lipase in 3 patients (3%). The pancreas was normal on imaging procedures in 77 (89%) patients and abnormal in 10 (11%) (chronic pancreatitis: 4, small cystic lesions: 6). The cystic lesions were mostly located in the pancreas head, probably corresponding to branch-duct intraductal papillary mucinous neoplasm. Conclusions. Increased pancreatic enzyme activities occur in 8% of hospitalized patients with non-pancreatic diseases, but pancreatic abnormalities will be found in only a few (11%), which are unlikely to need further investigation or therapy. Therefore, routine analysis of amylase or lipase activities in patients with non-pancreatic diseases is not indicated. [ABSTRACT FROM AUTHOR]

Marked hyperamylasaemia associated with an amylase-producing multiple myeloma appears to be a fairly unusual phenomenon. The present report describes a fatal case of multiple myeloma associated with paraneoplastic hyperamylasaemia without evidence of pancreatic or salivary gland involvement. Serum and urine amylase levels paralleled the myeloma response to chemotherapy and disease progression. The importance of paraneoplastic hyperamylasaemia as a useful myeloma marker to monitor disease progression and treatment response is emphasized. Conventional chemotherapy at diagnosis and salvage treatment with bortezomib at relapse failed to achieve a long-term response and to decrease the serum amylase to a normal level. Copyright © 2007 S.

Objective: Percutaneous transhepatic biliary intervention (PTBI) plays an important role in the management of biliary obstruction, and this may be complicated by acute pancreatitis. The aim of this study was to assess the incidence of acute pancreatitis following PTBI. Patients and methods: Patients who underwent PTBI between January 1992 and December 2003 in a tertiary referral centre were identified from the hospital database. Patients who did not have their amylase measured post-procedure were excluded, as acute pancreatitis might have been missed. Acute pancreatitis was defined as hyperamylasaemia of three times or more above normal in association with abdominal pain. Results: Over a 12-year period, 331 patients underwent 613 procedures. Serum amylase was measured after 134 procedures (21.9%) and was elevated in 26 of those (19.4%). There was no difference in the frequency of hyperamylasaemia between proximal and distal PTBI (14/73 [19.2%] vs 12/61 [19.7%] procedures, p=NS). However, acute pancreatitis developed after 4 of 61 (6.6%) distal PTBI (stent, n=3; internal–external catheter insertion, n=1) but not after proximal PTBI (cholangiography or external drainage) (p=0.041). The attacks were mild in three of the four patients. No pancreatitis-related deaths occurred. Conclusion: The risk of acute pancreatitis after distal PTBI is under-recognized and should be considered as a consent issue in patients scheduled for distal PTBI and when post-procedure abdominal pain ensues.

This study reports a case of a patient with lambda-light chain multiple myeloma who developed a high hyperamylasaemia of the salivary type during the disease and soon afterwards died. Ectopic production of amylase by myeloma cells has been described in a few cases and demonstrated by tissue culture and immunohistochemical techniques. The common characteristics of these cases were: salivary amylase isoenzyme increase, high tumor mass, extensive extra-medullary spread, extensive bone destruction and poor prognosis. In patients with amylase-producing multiple myeloma, the onset of hyperamylasaemia heralds a rapid disease progression; therefore, in these patients, a simple test such as serum amylase may represent a reliable disease activity index and provide an additional prognostic information.

Unlabelled: Pancreatitis in children is not common and can be associated with severe morbidity and mortality. We encountered 43 children, ranging in age from 2 to 18 years, with pancreatitis over the past 10 years. The diagnosis of pancreatitis was made in those patients who showed: (1) significant intra-operative pathology or; (2) clinical findings of pancreatic inflammation and laboratory confirmation. More than one third (16 cases) of the cases were due to trauma, other causes included systemic disease (10), structural disease (8), and toxins or drugs (4). Five cases were classified as idiopathic. Most of the patients presented with abdominal pain (95%) and vomiting (56%). Jaundice was found in 7 patients and an abdominal mass in 2. Morbidity included pseudocyst (10), relapse (4), hyperglycaemia (4) and miscellaneous problems. Eight (50%) of the patients with trauma and 6 (86%) of the patients with structural diseases required surgery. Other patients were managed conservatively with bowel rest, gastric decompression, intravenous fluid and total parenteral nutrition. One case had a fatal outcome. All the survivors did well in long term follow up. Relevant literature has been reviewed and the sensitivity of various diagnostic modalities compared and discussed. A lesser known association between pancreatitis and structural anomalies such as choledochal cyst is discussed. To our knowledge, the present review is the first on pancreatitis in Chinese children.Conclusion: Pancreatitis can occur from a wide variety of causes and may result in severe complications. Early diagnosis, close monitoring and aggressive intervention are mandatory to reduce morbidity and mortality. [ABSTRACT FROM AUTHOR]

Introduction: Capillary (finger prick) blood sampling is commonplace in paediatric practice but this method is prone to produce spurious laboratory results., Case Presentation: A five-year-old girl presented with abdominal pain, epigastric tenderness, tachycardia and reduced oxygen saturation. A venous blood sample haemolysed, and serum amylase on a finger prick sample was reported as 2831 units/L. The working diagnosis was acute pancreatitis and respiratory tract infection. A repeat amylase 9 h later was within the normal range. The patient was known to bite her fingers and the possibility of salivary contamination was considered. Serum isoenzyme analysis confirmed presence of high salivary amylase levels with no pancreatic amylase detected. A viral respiratory tract infection and buried gastrostomy bumper were eventually thought to account for the patient's presentation., Conclusion: Increased awareness of the potential for salivary contamination of serum amylase in finger prick samples may prevent misdiagnoses of pancreatitis.

Aim: To investigate the effectiveness of rectally administered indomethacin in the prophylaxis of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis and hyperamylasaemia in a multicentre study., Methods: A prospective, randomised, placebo-controlled multicentre study in five endoscopic units was conducted on 686 patients randomised to receive a suppository containing 100 mg indomethacin, or an inert placebo, 10-15 min before ERCP. Post-ERCP pancreatitis and hyperamylasaemia were evaluated 24 h following the procedure on the basis of clinical signs and laboratory parameters, and computed tomography/magnetic resonance imaging findings if required., Results: Twenty-one patients were excluded because of incompleteness of their data or because of protocol violation. The results of 665 investigations were evaluated: 347 in the indomethacin group and 318 in the placebo group. The distributions of the risk factors in the two groups did not differ significantly. Pancreatitis developed in 42 patients (6.3%): it was mild in 34 (5.1%) and severe in eight (1.2%) cases. Hyperamylaesemia occurred in 160 patients (24.1%). There was no significant difference between the indomethacin and placebo groups in the incidence of either post-ERCP pancreatitis (5.8% vs 6.9%) or hyperamylasaemia (23.3% vs 24.8%). Similarly, subgroup analysis did not reveal any significant differences between the two groups., Conclusion: 100 mg rectal indomethacin administered before ERCP did not prove effective in preventing post-ERCP pancreatitis.
