Background: Endoscopic retrograde cholangiopancreatography (ERCP) has become an important method to diagnose and treat biliary-pancreatic diseases. Perforations are infrequent but serious complications can occur during ERCPs. However, it is unclear which patients are suitable for surgery and when these patients should receive surgery. Aim: To analyze the outcome of 45 patients with endoscopic retrograde cholangiopancreatography (ERCP) related perforation. Materials and methods: We retrospectively reviewed all 45 patients with ERCP-related perforation between January 2003 and December 2017, and observed the location and causes of perforation, treatment strategies, and mortality. Results: Twenty thousand four hundred and seventy-nine patients received ERCP procedures from January 2003 to December 2017 in our digestive endoscopy center. Forty-five patients suffered from ERCP-related perforations. The incidence rate of ERCP-related perforations was 0.22%. Twenty-six patients suffered from periampullary perforations, 15 patients suffered from duodenal wall perforations, 1 patient suffered from a fundus perforation, 1 patient suffered from a residual gallbladder duct perforation, 1 patient suffered from a papillary diverticulum perforation, and 1 patient suffered from an intrahepatic bile duct perforation. Six patients with duodenal perforations underwent surgery, and the other patients received conservative treatment. One patient with a duodenal perforation and ERCP-related pancreatitis died of heart failure, and all the other patients recovered. The mortality rate was 2.2%. Conclusion: Endoscopic closure is seen as the first method for treating Stapfer type I perforations in the early phase, and surgery is seen as a remedial method when local treatment was failed. The Stapfer type II to type IV perforations can recover by conservative treatment.

BACKGROUND AND AIMS: Rifaximin has been recommended as a prophylactic drug for hepatic encephalopathy (HE) and spontaneous bacterial peritonitis (SBP). This study aims to explore whether low-dose rifaximin can prevent overall complications and prolong survival in cirrhotic patients. METHODS: In this multi-centre randomized open-labelled prospective study, 200 patients with decompensated cirrhosis were randomly assigned at a ratio of 1:1. Patients in rifaximin group were administered 400 mg rifaximin twice daily for 6 months, and all other therapeutic strategies were kept unchanged in both groups as long as possible. The primary efficacy endpoints were the incidence of overall complications and liver transplantation-free survival. The secondary endspoints were the incidence of each major cirrhosis-related complication, as well as the Child-Pugh score and class. RESULTS: The major baseline characteristics were similar in the two groups except for HE. The cumulative incidence and frequency of overall complications were significantly lower in rifaximin group than in the control group (p < 0.001). Though liver transplantation-free survival was not significantly different between the two groups, subgroup analysis showed rifaximin markedly prolonged liver transplantation-free survival in patients with Child-Pugh score ≥ 9 (p = 0.007). Moreover, rifaximin markedly reduced the episodes of ascites exacerbation (p < 0.001), HE (p < 0.001) and gastric variceal bleeding (EGVB, p = 0.031). The incidence of adverse events was similar in the two groups. CONCLUSION: Low-dose rifaximin significantly decreases the occurrence of overall complications, leading to prolonged survival in patients with advanced stages of cirrhosis in this trail. Further study should be carried out to compare the effect of this low-dose rifaximin with normal dose (1200 mg/day) rifaximin in preventing cirrhosis-related complications. CLINICAL TRIAL NUMBER: NCT02190357.

BACKGROUND: Moderately severe acute pancreatitis (MSAP) is a critical form of acute pancreatitis that is related with high morbidity and mortality. Severe Clostridium difficile infection (sCDI) is a serious and rare nosocomial diarrheal complication, especially in MSAP patients. Fecal microbiota transplantation (FMT) is a highly effective treatment for refractory and recurrent CDI (rCDI). However, knowledge regarding the initial use of FMT in patients suffering from sCDI is limited. CASE SUMMARY: Here, we report an MSAP patient complicated with sCDI who was treated by FMT as a first-line therapy. The patient was a 51-year-old man who suffered from diarrhea in his course of acute pancreatitis. An enzyme immunoassay was performed to detect toxins, and the result was positive for toxin-producing C. difficile and toxin B and negative for C. difficile ribotype 027. The colonoscopy revealed pseudomembranous colitis. Due to these findings, sCDI was our primary consideration. Because the patient provided informed consent for FMT treatment, we initially treated the patient by FMT rather than metronidazole. Diarrhea resolved within 5 d after FMT. The patient remained asymptomatic, and the follow-up colonoscopy performed 40 d after discharge showed a complete recovery. Our case is the first reported in China. CONCLUSION: This case explores the possibilities of initially using FMT to treat severe CDI. Moreover, FMT may become a critical component of the treatment for severe CDI in MSAP patients.

OBJECTIVES: This study aimed to compare the efficacy of percutaneous drainage (PCD) versus peritoneal lavage (PL) for the treatment for severe acute pancreatitis patients with pancreatic ascites (PAs). METHODS: Severe acute pancreatitis patients with PAs were randomly assigned within 3 days of onset of symptoms to receive either PL or PCD. The primary end point was a composite of mortality or major complications during hospitalization and within 1 month of discharge. Per-protocol analyses were performed. RESULTS: Between September 2011 and June 2014, 86 patients were randomly assigned to intervention with PL or PCD. Ultimately, 41 patients in the PCD group and 39 patients in the PL group completed the study. The primary end point occurred in 15 (36.6%) of 41 patients in the PCD group and in 17 (43.6%) of 39 patients in the PL group (risk ratio, 0.84; 95% confidence interval, 0.49-1.44; P = 0.27). Mortality or major complications did not differ between the groups. Percutaneous drainage reduced intra-abdominal hypertension; however, PL reduced the incidence of deep venous thrombosis and pancreatic encephalopathy and was associated with a reduced need for intervention. CONCLUSIONS: In our study, the PCD was not superior to the PL in reducing mortality or major complications in severe acute pancreatitis patients with PAs.

Serum alpha-fetoprotein (AFP) levels elevated in benign liver diseases (BLD) represent a challenge in hepatocellular carcinoma (HCC) diagnosis. The present study aimed to develop a simple method to identify HCC in AFP-elevated liver diseases based on combining serum fluorescence and general clinical data. Serum specimens and clinical data were collected from 201 HCC and 117 BLD (41 liver cirrhosis, 76 chronic hepatitis) patients with abnormal serum AFP levels. Dual serum fluorescence (autofluorescence and cell-free DNA-related fluorescence) intensities were sequentially measured and expressed as 6 fluorescence indicators. The diagnostic value of these fluorescence and clinical data were evaluated alone and in combination by the area under receiver operating characteristic curve (AUROC). All fluorescence indicators significantly differed between HCC and BLD and some of them were more valuable for diagnosing HCC than AFP (AUROC 0.782-0.801 vs. 0.752). The diagnostic model established with fluorescence indicators, AFP, hepatic function tests and age showed that AUROC, sensitivity, specificity and accuracy were 0.958 (95% CI 0.936-0.979), 92.0%, 88.9% and 92.3%, respectively, and positive rates in AFP-negative, early and small HCCs were 73.8%, 81.6% and 74.3%, respectively. In conclusion, the combination of dual serum fluorescence, AFP, hepatic function tests and age is simple and valuable for identifying HCC in serum AFP-elevated liver diseases.

BACKGROUND: Infected pancreatic necrosis (IPN) is a serious local complication of acute pancreatitis, with high mortality. Minimally invasive therapy including percutaneous catheter drainage (PCD) has become the preferred method for IPN instead of traditional open necrosectomy. However, the efficacy of double-catheter lavage in combination with percutaneous flexible endoscopic debridement after PCD failure is unknown compared with surgical necrosectomy. METHODS: A total of 27 cases of IPN patients with failure PCD between Jan 2014 and Dec 2015 were enrolled in this retrospective cohort study. Fifteen patients received double-catheter lavage in combination with percutaneous flexible endoscopic debridement, and 12 patients underwent open necrosectomy. The primary endpoint was the composite end point of major complications or death. The secondary endpoint included mortality, major complication rate, ICU admission length of stay, and overall length of stay. RESULTS: The primary endpoint occurrence rate in double-catheter lavage in combination with percutaneous flexible endoscopic debridement group (8/15, 53%) was significantly lower than that in open necrosectomy group (11/12, 92%) (RR = 1.71, 95% CI = 1.04 - 2.84, P < 0.05). Though the mortality between two groups showed no statistical significance (0% vs. 17%, P = 0.19), the rate of new-onset multiple organ failure and ICU admission length of stay in the experimental group was significantly lower than that in open necrosectomy group (13% vs. 58%, P = 0.04; 0 vs. 17, P = 0.02, respectively). Only 40% of patients required ICU admission after percutaneous debridement, which was markedly lower than the patients who underwent surgery (83%; P < 0.05). CONCLUSIONS: Double-catheter lavage in combination with percutaneous flexible endoscopic debridement showed superior effectiveness, safety, and convenience in patients with IPN after PCD failure as compared to open necrosectomy.

The efficacy and safety of polaprezinc combined with triple therapy was compared with triple therapy alone in the eradication of Helicobacter pylori. A randomized, parallel-group, open-label, controlled, prospective multicenter study was conducted in 11 cities in China. Treatment-naive patients with H. pylori-associated gastritis were randomly assigned to one of three arms for a 14-day treatment: Arm A triple therapy (omeprazole 20 mg, amoxicillin 1 g, and clarithromycin 500 mg, each twice daily) plus polaprezinc 75 mg twice daily; Arm B triple therapy plus polaprezinc 150 mg twice daily, or Arm C triple therapy alone. The rate of H. pylori eradication was the primary endpoint. Secondary endpoints were symptom improvement and lower incidence of adverse events. 303 patients completed the study- 106, 96, and 101 patients in Arms A, B, and C, respectively. Intention-to-treat (ITT) analysis showed that the rate of H. pylori eradication was significantly higher for Arms A (77.0%) and B (75.9%) compared to Arm C (58.6%) (P < 0.01), whereas there was no difference between Arms A and B (P = 0.90). Per-protocol (PP) analysis showed that the rate of H. pylori eradication was significantly higher for Arms A (81.1%) and B (83.3%) compared to Arm C (61.4%) (P < 0.01), whereas there was no significant difference between Arms A and B (P = 0.62). All three groups reported significant symptom improvement at 7, 14, and 28 days after treatment, compared to baseline (P < 0.0001). The adverse event rate for Arm B (5.1%) was higher than for Arms A (2.8%) (P = 0.04) and C (1.9%) (P = 0.02). There were no serious adverse events in any group. It appears that standard dose polaprezinc combined with triple therapy can significantly improve the H. pylori eradication rate, without an increase in toxicity.

BACKGROUND AND AIMS: Post-ERCP pancreatitis and hyperamylasemia are common complications of endoscopic retrograde cholangiopancreatography (ERCP), especially in high-risk patients. The aim of this study is to evaluate whether a raw rhubarb solution can reduce the incidence of PEP and post-ERCP hyperamylasemia. METHODS: From October 2012 to October 2013, 2100 patients received ERCP in our Endoscopic Center. Five hundred patients with high-risk factors were enrolled randomly into the raw rhubarb group (RG, 250 cases drank a raw rhubarb soak solution per 3 h until defecation after ERCP) and the control group (CG, 250 cases drank water after ERCP) in the study. The serum amylase concentration was measured. The abdominal pain, purge time and symptoms of patients were observed in the two groups. RESULTS: There were no differences in patient demographics, medical history, ERCP procedure, and patient- and procedure-related high-risk factors between the two groups. PEP incidence was 2% (5/250) in the RG group, which was lower than that in the CG group (7.6%, 19/250) (P < 0.01). The rate of post-ERCP hyperamylasemia was 5.2% (13/250) and 16.8% (42/250) in the RG group and CG group, respectively. The incidence of hyperamylasemia in the RG group was significantly lower than that in the CG group (P < 0.01). The incidence of abdominal pain 24 h after ERCP in the RG group was lower than that in the CG group (P < 0.01). No side effects were observed for raw rhubarb solution. CONCLUSIONS: A raw rhubarb solution is safe and effective in preventing the incidence of PEP and hyperamylasemia in high-risk patients.

The diagnosis of early, small and alpha-fetoprotein (AFP)-negative primary hepatic carcinomas (PHCs) remains a significant challenge. We developed a simple and robust approach to noninvasively detect these PHCs. A rapid, high-throughput and single-tube method was firstly developed to measure serum autofluorescence and cell-free DNA (cfDNA)-related fluorescence using a real-time PCR system, and both types of serum fluorescence were measured and routine laboratory data were collected in 1229 subjects, including 353 PHC patients, 331 liver cirrhosis (LC) patients, 213 chronic hepatitis (CH) patients and 332 normal controls (NC). The results showed that fluorescence indicators of PHC differed from those of NC, CH and LC to various extents, and all of them were not associated with age, gender, or AFP level. The logistic regression models established with the fluorescence indicators alone and combined with AFP, hepatic function tests and blood cell analyses were valuable for distinguishing early, small, AFP-negative and all PHC from LC, CH, NC and all non-PHC, with areas under the receiver operating characteristic curves 0.857-0.993 and diagnostic accuracies 80.2-97.7%. Conclusively, serum autofluorescence and cfDNA-related fluorescence are able to be rapidly and simultaneously measured by our simple method and valuable for diagnosing early, small and AFP-negative PHCs, especially integrating with AFP and conventional blood tests.

OBJECTIVES: To compare the value of emergent triglyceride (TG)-lowering therapies between early high-volume hemofiltration (HVHF) and low-molecular-weight heparin (LMWH) combined with insulin (LMWH+insulin) as well as their effects on the outcomes of hypertriglyceridemic pancreatitis (HTGP) patients. METHODS: In this randomized controlled trial, 66 HTGP patients presenting within 3 days after the onset of symptoms from August 2011 to October 2013 were assigned randomly to receive either HVHF or LMWH+insulin as an emergent TG-lowering therapy. Thirty-three patients were included in each group, and the therapy was started as soon as possible after admission. TG levels, clinical outcomes, and inflammatory biomarkers were compared between the 2 groups. RESULTS: Thirty-two individuals in the HVHF group and 34 in the LMWH+insulin group were included in the final analysis. Characteristics of the patients in both groups were roughly comparable. HVHF could remove TG from the plasma and achieve its target (<500 mg/dL) in approximately 9 hours, whereas the target was not achieved within 48 hours in patients receiving the LMWH+insulin treatment (P<0.05). However, no differences were found in terms of the majority of the clinical outcomes, including local pancreatic complications (P>0.05), the requirement of surgical intervention (P=0.49), mortality (P=0.49), and the duration of hospitalization (P=0.144). Furthermore, an unexpectedly higher incidence of persistent organ failure was observed in the HVHF group compared with the LMWH+insulin group (risk ratio with HVHF, 2.42; 95% confidence interval, 1.15-5.11; P=0.01). Hospital charges for patients in the HVHF group were approximately 2-fold higher than those for patients in the LMWH+insulin group (5.20±4.90 vs. 2.92±3.21, P=0.03). We selected a systemic inflammatory response syndrome score of at least 2 at baseline as a predictor of SAP patients, and the subgroup analyses showed that HVHF cannot improve the prognosis of the predicted SAP patients compared with the LMWH+insulin group. CONCLUSIONS: HVHF can lower TG levels more efficiently than LMWH+insulin therapy, but it is not superior in terms of clinical outcomes and costs. Further multicenter studies with large samples are required to clarify the feasibility of administering the HVHF treatment to HTGP patients (ChiCTR-TRC-13003274).

BACKGROUND AND STUDY AIMS: Gastrointestinal endoscopy procedures, such as endoscopic retrograde cholangiopancreatography (ERCP), endoscopic submucosal dissection (ESD), and colonoscopy are widely used for the diagnosis or treatment of digestive diseases. Perforation is a rare but potentially lethal complication. Large perforations usually require immediate endoscopic or surgical repair. Endoscopic closure using a nylon loop pouch suture is usually performed with a double-channel endoscope. This paper describes the endoscopic closure of large procedure-related perforations using a single-channel endoscope. PATIENTS AND METHODS: A total of 10 patients with large perforations (2.5â-â4.0âcm), which occurred during ERCP, ESD, or colonoscopy, were treated using the single-channel endoscope technique. RESULTS: All perforations were successfully closed using a nylon loop pouch suture through the single-channel endoscope. No surgery or further endoscopic intervention was required. CONCLUSIONS: Nylon loop pouch suture through a single-channel endoscope was easy to perform and was feasible for the closure of large gastrointestinal perforations.

Situs inversus viscerum (SIV) is a rare congenital condition characterized by complete transposition of all viscera. This anatomical pathology makes endoscopic retrograde cholangiopancreatography (ERCP) technically difficult. We report a new case of a 70-year-old Chinese male with total SIV who had obstructive jaundice. Magnetic resonance cholangiopancreatography demonstrated a number of stones in the gallbladder and common bile duct (CBD). Therapeutic ERCP was performed to relieve biliary obstruction and remove the CBD stones. This procedure started with the patient in a supine position and the endoscopist at the left side of the table. When the papilla was maintained, the patient was repositioned to a prone position and standard endoscopic sphincterotomy and endoscopic papillary balloon dilatation procedures were conducted. ERCP was performed successfully and relevant complications did not occur in this patient. We also present a review of the literature published between 1985 and 2014 in the PubMed and EMBASE databases. There were eight published cases during this period, with one each from America, Finland, India, Italy, South Korea and Pakistan, and two from Spain. Our case is the first reported in China.

BACKGROUND/AIMS: To compare the colonoscopy findings of a tertiary Chinese hospital with those of an American tertiary hospital. MATERIALS AND METHODS: Hundred consecutive colonoscopies performed in August 2008 at the First Affiliated Hospital of Nanchang University in China and at the Emory University Hospital, United States of America, were investigated. The endoscopic findings and the histopathology results were statistically compared. RESULTS: The average age of Chinese patients who underwent colonoscopy in this study was 45.23±15.38 years, whereas that of American patients was 55.38±12.11 years; no difference in sex ratio was observed (p=0.202) between the two populations. Screening colonoscopy accounted for 38% of patients in the American group and zero patients in the Chinese group. Polyps and diverticula were the most common findings in both groups. Abnormal findings in the American patients were three times higher than those in the Chinese patients. Proximal colon polyps were more common in the American group. Conversely, proximal colon diverticula were more common in the Chinese group. The prevalence of non-neoplasm lesions was not different between the two groups (p=0.232); the prevalence of adenomas significantly increased in patients who were more than 50 years old in both groups and was higher in the American group (p=0.038). CONCLUSION: The prevalence of bowel diseases in American patients was higher than that in Chinese patients. Polyps and diverticula were the main bowel abnormalities in both groups. Chinese patients lacked awareness of colonoscopy screening and should be enhanced aged 50 years old or older, because the prevalence of advanced neoplasia was increased in this age group in both groups.

AIM: To investigate the clinical features of Crohn's disease (CD) and intestinal tuberculosis (ITB) with a scoring system that we have developed. METHODS: A total of 25 CD and 40 ITB patients were prospectively enrolled from August 2011 to July 2012. Their characteristics and clinical features were recorded. Laboratory, endoscopic, histologic and radiographic features were determined. The features with a high specificity were selected to establish a scoring system. The features supporting CD scored +1, and those supporting ITB scored -1; each patient received a final total score. A receiver operating characteristic (ROC) curve was used to determine the best cut-off value for distinguishing CD from ITB. RESULTS: Based on a high specificity of differentiating between CD and ITB, 12 features, including longitudinal ulcers, nodular hyperplasia, cobblestone-like mucosa, intestinal diseases, intestinal fistula, the target sign, the comb sign, night sweats, the purified protein derivative test, the interferon-γ release assay (T-SPOT.TB), ring ulcers and ulcer scars, were selected for the scoring system. The results showed that the average total score of the CD group was 3.12 ± 1.740, the average total score of the ITB group was -2.58 ± 0.984, the best cutoff value for the ROC curve was -0.5, and the diagnostic area under the curve was 0.997, which was statistically significant (P < 0.001). The patients whose total scores were higher than -0.5 were diagnosed with CD; otherwise, patients were diagnosed with ITB. Overall, the diagnostic accuracy rate and misdiagnosis rate of this scoring system were 97% and 3%, respectively. CONCLUSION: Some clinical features are valuable for CD and ITB diagnosis. The described scoring system is key to differentiating between CD and ITB.

AIM: To access the efficacy of combination with amoxicillin and tetracycline for eradication of Helicobacter pylori (H. pylori), thus providing clinical practice guidelines. METHODS: PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Science Citation Index, China National Knowledge Infrastructure, Wanfang, and Chinese Biomedical Literature databases and abstract books of major European, American, and Asian gastroenterological meetings were searched. All clinical trials that examined the efficacy of H. pylori eradication therapies and included both tetracycline and amoxicillin in one study arm were selected for this systematic review and meta-analysis. Statistical analysis was performed with Comprehensive Meta-Analysis Software (Version 2). Subgroup, meta-regression, and sensitivity analyses were also carried out. RESULTS: Thirty-three studies met the inclusion criteria. The pooled odds ratio (OR) was 0.90 (95%CI: 0.42-1.78) for quadruple therapy with amoxicillin and tetracycline vs other quadruple regimens, and total eradication rates were 78.1% by intention-to-treat (ITT) and 84.5% by per-protocol (PP) analyses in the experimental groups. The pooled eradication rates of 14-d quadruple regimens with a combination of amoxicillin and tetracycline were 82.3% by ITT and 89.0% by PP, and those of 10-d regimens were 84.6% by ITT and 93.7% by PP. The OR by ITT were 1.21 (95%CI: 0.64-2.28) for triple regimens with amoxicillin and tetracycline vs other regimens and 1.81 (95%CI: 1.37-2.41) for sequential treatment with amoxicillin and tetracycline vs other regimens, respectively. CONCLUSION: The effectiveness of regimens employing amoxicillin and tetracycline for H. pylori eradication may be not inferior to other regimens, but further study should be necessary.

BACKGROUND: Crohn's disease and intestinal tuberculosis (ITB) are chronic granulomatous disorders that are difficult to distinguish. Computed tomographic enterography (CTE) yields striking ï¬ndings for Crohn's disease in the small bowel but its role in differentiating Crohn's from ITB is undefined. This prospective study aimed to investigate the value of CTE for differential diagnosis between Crohn's disease and ITB. PATIENTS AND METHODS: 105 consecutive patients (67 Crohn's, 38 ITB) who underwent CTE and colonoscopy were enrolled. CTE findings and colonoscopic parameters were compared between Crohn's disease and ITB by blinded reviewers. Based on univariate and multiple logistic regression analyses, a diagnostic algorithm combining colonoscopy and CTE was formulated. and its performance validated on 60 new patients (40 Crohn's, 20 ITB). RESULTS: On univariate analysis of CTE findings, proximal small-bowel involvement, asymmetrical mural thickening, segmental small-bowel lesions, mural stratification, the comb sign, and mesentery fibrofatty proliferation were significantly more common in Crohn's disease, whereas mesenteric lymph node change (calcification or central necrosis) and focal ileocecal lesions were more common in ITB. On multivariate analysis, segmental small-bowel involvement (odds ratio [OR] 0.104, 95â% confidence interval [95â%CI] 0.022â-â0.50), and comb sign (OR 0.02, 95â%CI 0.003â-â0.26) were independent predictors of Crohn's. Combining CTE and colonoscopic findings increased the accuracy of diagnosing either Crohn's disease or ITB from 66.7â% (70/105) to 95.2â% (100/105) in the development set (Pâ<â0.001). Sensitivity, speciï¬city, and area under the curve for receiver-operating characteristic (ROC) in the validation dataset were 92.5â%, 80â%, and 0.862 (95â%CI 0.75â-â0.98), respectively. CONCLUSIONS: CTE adds unique information to colonoscopy in differential diagnosis between Crohn's disease and ITB, allowing correct diagnosis in most patients.

BACKGROUND AND STUDY AIM: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) remains the most common complication of ERCP. Somatostatin may inhibit pancreatic secretion and has been tested for PEP prophylaxis. However, the results of previous studies are inconsistent. The aim of the current study was to investigate whether somatostatin can reduce the incidence of PEP. PATIENTS AND METHODS: The study was a multicenter, open-label, randomized controlled trial. A total of 908 patients with normal amylase levels who were undergoing ERCP were randomized to receive somatostatin 250âµg bolus injection before ERCP and 250âµg/hour intravenous infusion for 11 hours after ERCP (somatostatin group) or no somatostatin treatments (control group). The incidences of PEP and hyperamylasemia were compared in the two groups. RESULTS: The full analysis set included 900 patients (445 in the somatostatin group, 455 in the control group). PEP developed in 34 patients (7.5â%) in the control group (95â% confidence interval [CI] 5.4â%â-â10.3â%) and in 18 patients (4.0â%) in the somatostatin group (95â%CI 2.6â%â-â6.3â%; Pâ=â0.03). Hyperamylasemia occurred in 46 patients (10.1â%) in the control group (95â%CI 7.7â%â-â13.2â%) and in 27 patients (6.1â%) in the somatostatin group (95â%CI 4.2â%â-â8.7â%; Pâ=â0.03). No perforation or death occurred during the study. CONCLUSIONS: This study showed that somatostatin was effective and safe for the prevention of PEP and hyperamylasemia in ERCP patients.(ClinicalTrials.gov number, NCT01431781).
