RESUMO
BACKGROUND: drug-induced pancreatitis is an unexplored entity. METHODS: a retrospective cohort study was performed at a referral center. Patients with drug-induced acute pancreatitis between 2008 and 2018 were included. Baseline patient characteristics, involved drugs, clinical course and recurrence were analyzed. RESULTS: drug-induced pancreatitis represented 2.8 % of acute pancreatitis (47/1,665) and 18 different drugs were involved (thiopurines 61.8 %). The latency period was less than one month in 87.2 % of cases. Pancreatitis was mild in 89.3 % and recurrence risk was 2.3 %. CONCLUSION: drugs are a rare cause of pancreatitis, which mostly occurs within the first month of treatment, is usually mild and is associated with a low risk of recurrence.

Pancreatic fluid collections frequently occur in the context of moderate and severe acute pancreatitis, and may also appear as a complication of chronic pancreatitis, pancreatic surgery or trauma. It is essential to adhere to the Atlanta classification nomenclature that subclassifies them into four categories (acute peripancreatic fluid collections, acute necrotic collections, pseudocysts, and walled-off necrosis) since it has an impact on prognosis and management. Pseudocysts and walled-off pancreatic necrosis are encapsulated pancreatic fluid collections characterized by a surrounding inflammatory wall, which typically develops three to four weeks after the onset of acute pancreatitis. Most pancreatic fluid collections resolve spontaneously and do not require intervention. However, when they become symptomatic or complicated drainage is indicated, and endoscopic ultrasound-guided drainage has become first-line treatment of encapsulated collections. Drainage of pseudocysts is relatively straightforward due to their liquid content. However, in walled-off necrosis the presence of solid necrotic debris can make treatment more challenging and therefore multidisciplinary management in experienced centers is recommended, being a step-up approach the current standard of care. In this review, we aim to address the management of pancreatic fluid collections with an especial focus on endoscopic drainage.

Endoscopic treatment of pancreatic ductal malformations causing recurrent acute pancreatitis, such as pancreas divisum or ansa pancreatica, is mainly based on the sphincterotomy of the minor papilla. However, the technical complexity of conventional endoscopic retrograde cholangiopancreatography (ERCP) is increased in patients presenting anatomical variants like these and it may be unsuccessful. We report the case of a pancreas divisum combined with ansa pancreatica and describe the cannulation and sphincterotomy of the minor papilla using an ultrasound-assisted Rendez-Vous technique.

BACKGROUND: Data about use and effectiveness of mercaptopurine in inflammatory bowel disease are relatively limited. AIMS: To assess the possible therapeutic indications, efficacy and safety of mercaptopurine as an alternative to azathioprine in inflammatory bowel disease. METHODS: Retrospective observational study in patients treated with mercaptopurine in a total cohort of 1,574 patients with inflammatory bowel disease. RESULTS: One hundred and fifty-two patients received mercaptopurine, 15.7% of these patients as an initial thiopurine, 5.3% after azathioprine failure, and 79% after azathioprine intolerance. In 52.6% of patients (n = 80), adverse effects of mercaptopurine occurred, resulting in withdrawal in 49 of them. Mercaptopurine was effective in 39% of cases (95% CI 31-48%). In the remaining patients, failure was due mainly to withdrawal due to side effects (55.1%) and therapeutic step-up (33.7%). The average total time of mercaptopurine exposure was 36 months (IQR: 2-60). Myelotoxicity with mercaptopurine was more common in patients with intermediate TPMT activity than in those with normal activity (p = 0.046). CONCLUSIONS: In our setting, mercaptopurine is primarily used as a rescue therapy in patients with azathioprine adverse effects. This could explain its modest efficacy and the high rate of adverse effects. However, this drug is still an alternative in this group of patients, before a therapeutic step-up to biologics is considered.

INTRODUCTION: Variceal upper gastrointestinal bleeding (UGIB) can trigger acute hypoxic hepatitis (AHH). The aim of this study was to analyse the incidence, associated risk factors and mortality of AHH after variceal UGIB. PATIENTS AND METHODS: Retrospective study of cirrhotic patients with variceal UGIB, classified into 2 groups according to the development of AHH. AHH was diagnosed when AST and ALT reached levels 10 times above the upper limit of normal, after ruling out other causes of hepatitis. The standard initial treatment consisted of haemodynamic support, emergency endoscopy with rubber band ligation, somatostatin and antibiotics. In the case of failure of primary haemostasis, a transjugular intrahepatic portosystemic shunt (TIPS) was implanted. Both groups (AHH and non-AHH) were compared. RESULTS: Sixty-eight cirrhotic patients with variceal UGIB admitted to the gastroenterology department of Hospital Ramón y Cajal between January 2007 and March 2012 were analysed. Eleven of these patients (16.2%) developed AHH. Univariate analysis showed the following items as risk factors: diabetes (OR: 7.5; CI: 1.9-29), shock (OR: 8.5; CI: 2.06-34) and persistent bleeding (OR: 9.0, CI: 1.6-49, P=.03). However, multivariate analysis confirmed only diabetes (OR: 8.61; CI: 1.4-52.5) and shock (OR: 7.58; CI: 1.26-45.51) as risk factors. Mortality rate in the AHH group was 45%, compared to 10.5% in the non-HAA group (P=.012). CONCLUSIONS: AHH after variceal UGIB occurred in 16.2% of cirrhotic patients and was associated with a poorer prognosis, with a mortality rate of 45%. Our findings suggest that diabetes and shock are risk factors for the development of AHH. Early identification of at-risk patients could therefore help prevent AHH.

According to the main international clinical guidelines, the recommended treatment for locally-advanced rectal cancer is neoadjuvant chemoradiotherapy followed by surgery. However, doubts have been raised about the appropriate definition of clinical complete response (cCR) after neoadjuvant therapy and the role of surgery in patients who achieve a cCR. Surgical resection is associated with significant morbidity and decreased quality of life (QoL), which is especially relevant given the favourable prognosis in this patient subset. Accordingly, there has been a growing interest in alternative approaches with less morbidity, including the organ-preserving watch and wait strategy, in which surgery is omitted in patients who have achieved a cCR. These patients are managed with a specific follow-up protocol to ensure adequate cancer control, including the early identification of recurrent disease. However, there are several open questions about this strategy, including patient selection, the clinical and radiological criteria to accurately determine cCR, the duration of neoadjuvant treatment, the role of dose intensification (chemotherapy and/or radiotherapy), optimal follow-up protocols, and the future perspectives of this approach. In the present review, we summarize the available evidence on the watch and wait strategy in this clinical scenario, including ongoing clinical trials, QoL in these patients, and the controversies surrounding this treatment approach.

Background and study aims Endoscopic ultrasound (EUS)-guided drainage has become first-line treatment for pancreatic fluid collections (PFC). The aim of this study was to compare the effectiveness and safety of biliary fully-covered self-expandable metal stents (BFCSEMS) and lumen-apposing metal stents with electrocautery (EC-LAMS). Patients and methods From April 2008 to March 2017, consecutive patients with symptomatic PFC drained under EUS-guidance with metal stents were included. Patients drained with EC-LAMS were considered the study group and those drained with BFCSEMS the control group.âTwo primary endpoints were evaluated: effectiveness (defined as reduction ofâ≥â50â% of PFC size in cross-sectional imaging and improvement of symptoms 6 months after the transmural drainage) and safety. Results Thirty patients were drained with EC-LAMS and 60 patients with BFCSEMS.âPatients and PFC baseline characteristics in both groups were similar. Use of a coaxial double pigtail plastic stent and a nasocystic lavage catheter was significantly less frequent in patients drained with EC-LAMS (33â% vs. 100â%, and 13â% vs. 58â%, respectively; P â<â0.0001). Technical success was 100â% in both groups. Procedure time wasâ<â30 minutes in all patients drained with EC-LAMS and over 30 minutes in all patients drained with BFCSEMS ( P â=â0.0001). Clinical success was higher with a tendency to significance in patients drained with EC-LAMS (96â% vs. 82â%, P â=â0.055) and the adverse event rate was lower (4â% vs. 18â%, P â=â0.04). No case of procedure-related mortality was recorded. Conclusions EC-LAMS and BFCSEMS are both effective for EUS-guided drainage of PFC. However, EC-LAMS requires less time to be performed and appears to be safer.
RESUMO
BACKGROUND: Population aging and comorbidity are leading to an increase in patients unfit for cholecystectomy. AIMS: To evaluate whether endoscopic biliary sphincterotomy after a first episode of acute gallstone pancreatitis reduces the risk of pancreatitis recurrence and gallstone-related events in non-surgical candidates. METHODS: Retrospective study of patients admitted for a first episode of acute gallstone pancreatitis rejected for cholecystectomy between 2013-2018. The role of endoscopic sphincterotomy was evaluated by adjusting for age, severity of pancreatitis, and presence of choledocholithiasis. RESULTS: We included 247 patients (mean age 80⯱â¯12â¯years; Charlson index: 5; severity of pancreatitis: 72% mild). Sphincterotomy was performed in 23.9%. Recurrence of pancreatitis occurred in 17.4% patients (median follow-up: 426â¯days). The one-year cumulative incidence of a new episode of pancreatitis was 1.8% (95% confidence interval [CI]: 0.2-12%) and 23% (95% CI: 17-31%) in patients with and without sphincterotomy, respectively (pâ¯=â¯0.006). In multivariate analysis, sphincterotomy showed a protective role for recurrence of pancreatitis (adjusted hazard ratio [HR]: 0.29, 95% CI: 0.08-0.92, pâ¯=â¯0.037) and for any gallstone-related event (HR 0.46, 95% CI: 0.21-0.98, pâ¯=â¯0.043). CONCLUSIONS: Endoscopic biliary sphincterotomy reduced the risk of gallstone pancreatitis recurrence and other biliary-related disorders in patients with a first episode of pancreatitis non-candidates for cholecystectomy.
