Splenic Artery Pseudoaneurysm Causing Massive Hematemesis 10 Years After Necrotizing Pancreatitis.

We report a case of a 54-year-old male presenting to a regional hospital with severe hematemesis and hemodynamic instability. His medical history was significant for a previous episode of alcoholic necrotizing pancreatitis and pseudocyst, requiring cystoenterostomy drainage and debridement 10 years prior. He underwent multiple gastroscopies and one emergency laparotomy which failed to definitively treat the bleeding. A splenic artery pseudoaneurysm was diagnosed with computed tomography angiography, adjacent to the previous cystoenterostomy site. The patient was transferred to a major tertiary center with access to interventional radiology and underwent successful embolization of the pseudoaneurysm.

Manejo actual de la pancreatitis aguda idiopática y la pancreatitis aguda recurrente / Current management of acute idiopathic pancreatitis and acute recurrent pancreatitis

La pancreatitis aguda es una entidad de notable importancia debido a su elevada incidencia y a su no desdeñable morbimortalidad. Se conoce como pancreatitis aguda idiopática aquella en la que no se consigue determinar la causa del cuadro tras un estudio básico inicial. Conocer la etiología subyacente permite plantear un tratamiento dirigido para así disminuir el riesgo de recurrencia. La ecoendoscopia y la colangiografía por resonancia magnética son las pruebas de elección para profundizar en el estudio etiológico. La principal causa es la enfermedad litiásica no diagnosticada en el estudio inicial, cuyo tratamiento de elección es la colecistectomía. Por otra parte, la pancreatitis aguda recurrente se diagnostica tras la existencia de 2 o más episodios de pancreatitis aguda. El objetivo de esta revisión es proporcionar una aproximación actualizada de estas 2 entidades, repasando aspectos de su epidemiología, diagnóstico y alternativas terapéuticas disponibles

Acute pancreatitis is an entity of notable importance due to its high incidence and its non-negligible morbidity and mortality. Idiopathic acute pancreatitis is that in which the cause of the clinical condition cannot be determined after an initial basic study. Understanding the underlying aetiology enables clinicians to propose a targeted treatment to reduce the risk of recurrence. Endoscopic ultrasonography and magnetic resonance cholangiopancreatography are the tests of choice to deepen the aetiological study. The main cause is undiagnosed lithiasic disease in the initial study, whose treatment of choice is cholecystectomy. Moreover, recurrent acute pancreatitis is diagnosed after 2 or more episodes of acute pancreatitis. The objective of this review is to provide an updated approach for these 2 entities, reviewing aspects of their epidemiology, diagnosis and available alternative therapies

Mass forming chronic pancreatitis mimicking pancreatic cystic neoplasm: A case report.

Mass forming chronic pancreatitis is very rare. Diagnosis could be done by the pathologic findings of focal inflammatory fibrosis without evidence of tumor in pancreas. A 34-year-old man presented with right upper abdominal pain for a few weeks and slightly elevated bilirubin level on clinical findings. Radiological findings of multidetector-row computed tomography, magnetic resonance (MR) imaging with MR cholangiopancreatography and endoscopic ultrasonography revealed focal branch pancreatic duct dilatation with surrounding delayed enhancing solid component at uncinate process and head of pancreas, suggesting branch duct type intraductal papillary mucinous neoplasm. Surgery was done and pathology revealed the focal chronic inflammation, fibrosis, and branch duct dilatation. Herein, I would like to report the first case report of mass forming chronic pancreatitis mimicking pancreatic cystic neoplasm.

The lifestyle influence on alcoholic pancreatitis versus alcoholic liver disease: a case-control study.

OBJECTIVE: To evaluate the association of lifestyle with the development of alcoholic liver disease (ALD) or alcoholic pancreatitis (AlcP). METHODS: A case-control study was conducted on 80 patients attending a tertiary university hospital, subdivided into three groups: ALD (n = 34), AlcP (n = 21) and a control (CT) group (n = 25) of alcohol abusers without clinical evidence of hepatic or pancreatic disease. Participants were interviewed regarding alcohol consumption, tobacco use and diet. A physical examination was concomitantly performed and we had access to their complementary investigation. RESULTS: We included 10 females and 70 males (mean age 57 ± 10 years). The pure amount of alcohol consumed by the ALD group was significantly higher than the AlcP group, regarding both daily (grams/day) and lifetime (kilograms) consumptions (p = .018 and p = .009, respectively); no statistically significant differences were seen with the CT group. We found no differences regarding the beverage type or drinking outside meals. Smoking was very common in every study group, with higher consumptions and a significantly higher prevalence of ever smokers in the AlcP group, in comparison with ALD and CT patients (p = .033 and p = .036, respectively). There were significant differences in the patients' eating habits before the onset of disease between groups (p < .001), with ALD subjects reporting a less abundant diet and AlcP a more abundant diet in the past; most of the controls had unchanged habits. CONCLUSION: We found differences in lifestyle between ALD and AlcP, not considered sufficient to explain the subjects' susceptibility to one disease or the other.

Dual drainage using a percutaneous pancreatic duct technique contributed to resolution of severe acute pancreatitis.

A 66-year-old man was admitted for severe acute alcoholic pancreatitis with infected pancreatic necrosis (IPN). Abdominal computed tomography revealed an inflamed pancreatic head, a dilated main pancreatic duct (MPD), and a large cavity with heterogeneous fluid containing gas adjacent to the pancreatic head, and extending to the pelvis. The cavity was drained percutaneously near the pancreatic head on admission; another tube was inserted into the pelvic cavity on hospital day 3. The drained fluid contained pus with high amylase concentration. Nasopancreatic drainage tube placement was unsuccessfully attempted on hospital day 9. On hospital day 23, percutaneous puncture of the MPD and placement of a pancreatic duct drainage tube was performed. Pancreatography revealed major extravasation from the pancreatic head. The IPN cavity receded; the percutaneous IPN drainage tube was removed on hospital day 58. On hospital day 83, the pancreatic drainage was changed to a transpapillary pancreatic stent, and the patient was discharged. Measuring the amylase concentration of peripancreatic fluid collections can aid in the diagnosis of pancreatic duct disruption; moreover, dual percutaneous necrotic cavity drainage plus pancreatic duct drainage may be essential for treating IPN. If transpapillary drainage tube placement is difficult, percutaneous pancreatic duct drainage may be feasible.

Pancreatoduodenectomy for groove pancreatitis Report of two cases.

Groove pancreatitis is a rare condition with patients having clinical characteristics similar to those of chronic pancreatitis. Differentiating on clinical and radiological basis between groove pancreatitis and paraduodenal head cancer can be extremely challenging. Due to diagnostic uncertainty and to poor response to medical treatment surgery may offer these patients the best chance of cure. As the main localization of the inflammatory process is at the groove between the duodenum and the head of the pancreas, pancreato-duodenectomy is proposed as the most reliable surgical procedure. We report about two patients presenting with clinical and radiological features suggesting a groove pancreatitis in which control of symptoms was achieved by pancreatoduodenectomy. KEY WORDS: Groove pancreatitis, Paraduodenal pancreatic cancer.

Modified single transluminal gateway transcystic multiple drainage technique for a huge infected walled-off pancreatic necrosis: A case report.

We report a successful endoscopic ultrasonography-guided drainage of a huge infected multilocular walled-off necrosis (WON) that was treated by a modified single transluminal gateway transcystic multiple drainage (SGTMD) technique. After placing a wide-caliber fully covered metal stent, follow-up computed tomography revealed an undrained subcavity of WON. A large fistula that was created by the wide-caliber metal stent enabled the insertion of a forward-viewing upper endoscope directly into the main cavity, and the narrow connection route within the main cavity to the subcavity was identified with a direct view, leading to the successful drainage of the subcavity. This modified SGTMD technique appears to be useful for seeking connection routes between subcavities of WON in some cases.

Percutaneous thrombin injection under sonographic guidance for exclusion of non-catheterizable post-pancreatitis pseudoaneurysm of the superior mesenteric artery: a minimally invasive and expeditious treatment option.

Post-pancreatitis pseudoaneurysms are not uncommon. They have a high associated mortality due to a propensity to rupture. Current standards of treatment advocate immediate intravascular interventions. We describe two cases of alcohol-related post-acute pancreatitis pseudoaneurysms arising from the second-order branches of the superior mesenteric artery (SMA) that were endoluminally inaccessible. Both cases were successfully treated with percutaneous thrombin injection into the pseudoaneurysm sac under ultrasound guidance. We suggest that endoluminally inaccessible pseudoaneurysms that are percutaneously accessible can be expeditiously treated with percutaneous thrombin injection. Further, due to the efficaciousness of this procedure, it could be considered as a first-line minimally invasive therapeutic option.

Repeated transabdominal ultrasonography is a simple and accurate strategy to diagnose a biliary etiology of acute pancreatitis.

OBJECTIVES: Transabdominal ultrasonography (US) usually reveals diagnosis of biliary acute pancreatitis (AP). Guidelines suggest repeating US in AP patients without cause at first examination. This approach has been poorly investigated, as well as the accuracy of repeated US as compared with that of magnetic resonance cholangiopancreatography. This study aims at evaluating the diagnostic accuracy of repeated US for biliary AP. METHODS: The accuracy of each test for diagnosis of biliary AP was evaluated according to the final diagnosis. Comparison between tests was obtained by examining the areas under the receiver operating characteristic curves. RESULTS: Among 155 patients, the etiology was biliary in 52% and alcoholic in 20%. The accuracy of the first US alone and of the 2 combined examinations for a biliary etiology were 66% and 83%, respectively. Comparison of receiver operating characteristic curves showed a better performance of repeated US (difference between areas under the curve, 0.135; 95% confidence interval, 0.02-0.24; P = 0.021). Magnetic resonance cholangiopancreatography had high specificity (93%) but low sensitivity (62%), with 76% accuracy. The accuracy of the combination of the 2 US examinations and of elevated alanine transferase was 87%. CONCLUSIONS: Repeated US is effective for biliary AP diagnosis. The combination of repeated US examinations and biochemical tests seems an effective approach, whereas magnetic resonance cholangiopancreatography might be restricted to selected cases.

Microbiologic analysis of peri-pancreatic fluid collected during EUS in patients with pancreatitis: impact on antibiotic therapy.

BACKGROUND: Pancreatitis is a potentially life-threatening condition frequently accompanied by peri-pancreatic fluid collections (PPFC), such as pseudocysts or pancreatic necrosis. Aspiration of PPFCs during EUS interventions for microbiologic analysis is still rarely performed in clinical routine. OBJECTIVE: To evaluate the role of routine microbiologic analysis of PPFCs and its impact on antibiotic therapy in patients with pancreatitis. DESIGN: Prospective, observational, multicenter study. SETTING: Four treatment centers. PATIENTS: A total of 44 consecutive patients who presented for endoscopic treatment of PPFCs were included. INTERVENTION: Concomitantly, PPFC during intervention and concomitant blood cultures were obtained. MAIN OUTCOME MEASUREMENTS: Microbiologic examination of PPFCs and blood samples. RESULTS: Colonization of PPFCs was found in 59% of PPFC cultures, whereas all but 2 concomitant blood cultures showed no microbial growth. Risk factors for a colonization were the presence of necrosis (P = .006), acute pancreatitis (P = .033), leukocytosis (P = .001), elevated C-reactive protein levels (P = .003), fever (P = .02), turbid material (P = .031), and longer hospital stay (P = .003). In 23 patients with fluid colonization despite empiric antibiotic therapy, the treatment had to be adjusted in 18 patients (78%) according to the observed antibiotic susceptibility profile. LIMITATIONS: Contamination cannot be totally excluded. CONCLUSION: The microbiologic colonization of PPFCs in patients with pancreatitis is common. Only the direct microbiologic analysis of PPFCs, but not of blood cultures, is useful to optimize an effective antibiotic therapy in patients with pancreatitis.
