Acid suppression therapy, gastrointestinal bleeding and infection in acute pancreatitis - An international cohort study

BACKGROUND: Acid suppressing drugs (ASD) are generally used in acute pancreatitis (AP); however, large cohorts are not available to understand their efficiency and safety. Therefore, our aims were to evaluate the association between the administration of ASDs, the outcome of AP, the frequency of gastrointestinal (GI) bleeding and GI infection in patients with AP. METHODS: We initiated an international survey and performed retrospective data analysis on AP patients hospitalized between January 2013 and December 2018. RESULTS: Data of 17,422 adult patients with AP were collected from 59 centers of 23 countries. We found that 23.3% of patients received ASDs before and 86.6% during the course of AP. ASDs were prescribed to 57.6% of patients at discharge. ASD administration was associated with more severe AP and higher mortality. GI bleeding was reported in 4.7% of patients, and it was associated with pancreatitis severity, mortality and ASD therapy. Stool culture test was performed in 6.3% of the patients with 28.4% positive results. Clostridium difficile was the cause of GI infection in 60.5% of cases. Among the patients with GI infections, 28.9% received ASDs, whereas 24.1% were without any acid suppression treatment. GI infection was associated with more severe pancreatitis and higher mortality. CONCLUSIONS: Although ASD therapy is widely used, it is unlikely to have beneficial effects either on the outcome of AP or on the prevention of GI bleeding during AP. Therefore, ASD therapy should be substantially decreased in the therapeutic management of AP

Endoscopic papillectomy for ampullary lesions in patients with familial adenomatous polyposis compared with sporadic lesions:A propensity score-matched cohort

Background Familial adenomatous polyposis (FAP) is a rare inherited syndrome that predisposes the patient to cancer. Treatment of FAP-related ampullary lesions is challenging and the role of endoscopic papillectomy has not been elucidated. We retrospectively analyzed the outcomes of endoscopic papillectomy in matched cohorts of FAPrelated and sporadic ampullary lesions (SALs). Methods This retrospective multicenter study included 1422 endoscopic papillectomy procedures. Propensity score matching including age, sex, comorbidity, histologic subtype, and size was performed. Main outcomes were complete resection (R0), technical success, complications, and recurrence. Results Propensity score matching identified 202 patients (101 FAP, 101 SAL) with comparable baseline characteristics. FAP patients were mainly asymptomatic (79.2% [95 %CI 71.2-87.3] vs. 46.5% [95 %CI 36.6-56.4]); P &lt; 0.001). The initial R0 rate was significantly lower in FAP patients (63.4% [95%CI 53.8-72.9] vs. 83.2% [95%CI 75.8-90.6]; P = 0.001). After repeated interventions (mean 1.30 per patient), R0 was comparable (FAP 93.1% [95%CI 88.0-98.1] vs. SAL 97.0% [95%CI 93.7-100]; P = 0.19). Adverse events occurred in 28.7%. Pancreatitis and bleeding were the most common adverse events in both groups. Severe adverse events were rare (3.5 %). Overall, 21 FAP patients (20.8% [95%CI 12.7-28.8]) and 16 SAL patients (15.8% [95%CI 8.6-23.1]; P = 0.36) had recurrence. Recurrences occurred later in FAP patients (25 [95 %CI 18.3-31.7] vs. 2 [95 %CI CI 0.06-3.9] months). Conclusions Endoscopic papillectomy was safe and effective in FAP-related ampullary lesions. Criteria for endoscopic resection of ampullary lesions can be extended to FAP patients. FAP patients have a lifetime risk of relapse even after complete resection, and require long-time surveillance.</p

Discharge protocol in acute pancreatitis: an international survey and cohort analysis.

There are several overlapping clinical practice guidelines in acute pancreatitis (AP), however, none of them contains suggestions on patient discharge. The Hungarian Pancreatic Study Group (HPSG) has recently developed a laboratory data and symptom-based discharge protocol which needs to be validated. (1) A survey was conducted involving all members of the International Association of Pancreatology (IAP) to understand the characteristics of international discharge protocols. (2) We investigated the safety and effectiveness of the HPSG-discharge protocol. According to our international survey, 87.5% (49/56) of the centres had no discharge protocol. Patients discharged based on protocols have a significantly shorter median length of hospitalization (LOH) (7 (5;10) days vs. 8 (5;12) days) p < 0.001), and a lower rate of readmission due to recurrent AP episodes (p = 0.005). There was no difference in median discharge CRP level among the international cohorts (p = 0.586). HPSG-protocol resulted in the shortest LOH (6 (5;9) days) and highest median CRP (35.40 (13.78; 68.40) mg/l). Safety was confirmed by the low rate of readmittance (n = 35; 5%). Discharge protocol is necessary in AP. The discharge protocol used in this study is the first clinically proven protocol. Developing and testifying further protocols are needed to better standardize patients' care
