Background Endoscopic transpapillary gallbladder drainage (ETGBD) and endoscopic ultrasound-guided gallbladder drainage (EUSGBD) are alternatives to percutaneous gallbladder drainage (PCGBD) for patients with acute cholecystitis who are unfit for surgery. Data comparing these modalities are limited and have reported conflicting results. Methods We searched multiple databases from inception to May 2019 to identify studies that reported on ETGBD, EUSGBD, and PCGBD in the management of acute cholecystitis in patients with a high surgical risk. Aims were to compare the pooled rates of technical success, clinical success, adverse events, and disease recurrence. Results 1223 patients (22 studies), 557 patients (14 studies), and 13 351 patients (46 studies) were treated by ETGBD, EUSGBD, and PCGBD, respectively. The pooled technical and clinical successes were: ETGBD 83 % (95 % confidence interval [CI] 80.1 – 85.5, I 2 = 29) and 88.1 % (95 %CI 83.6 – 91.4, I 2 = 50), respectively; EUSGBD 95.3 % (95 %CI 92.8 – 96.9, I 2 = 0) and 96.7 % (95 %CI 94.0 – 98.2, I 2 = 0), respectively; and PCGBD 98.7 % (95 %CI 98.0 – 99.1, I 2 = 0) and 89.3 % (95 %CI 86.6 – 91.5, I 2 = 84), respectively. Clinical success with EUSGBD was significantly superior to the other approaches. All complications were comparable between the groups. Pancreatitis occurred with ETGBD in 5.1 % (95 %CI 3.5 – 7.3), whereas bleeding and perforation occurred with EUSGBD in 4.3 % (95 %CI 2.7 – 6.8) and 3.7 % (95 %CI 2.3 – 6.0), respectively. Stent migration occurred with PCGBD in 7.4 % (95 %CI 5.5 – 10.0). Conclusion EUSGBD demonstrated better clinical success than ETGBD and PCGBD in the management of acute cholecystitis patients at high surgical risk.

INTRODUCTION: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing the pandemic of coronavirus disease 2019 (COVID-19) is a global health crisis. Possible pancreatic involvement has recently been observed in these patients; however, its significance is unclear. The aim of this study was to evaluate the association of significantly elevated lipase with disease outcomes. METHODS: Data about demographics, symptoms, laboratory values, and clinical outcomes were collected for 1,003 consecutive patients testing positive for COVID-19. Elevated lipase was defined as greater than 3 times the upper limit of normal (>3 × ULN). Baseline characteristics among patients with or without elevated lipase were compared using Fisher exact test or Student t -test for categorical or numerical variables, respectively. Logistic regression was used to evaluate the association of lipase levels with primary clinical outcomes (intensive care unit admission and intubation) adjusted for age, sex, body mass index, history of diabetes, and hypertension. RESULTS: Of 1,003 patients with COVID-19, 83 had available lipase levels and were all admitted to the hospital. Of 83, 14 (16.8%) had elevated lipase (>3 × ULN), which was associated with higher rates of leukocytosis ( P < 0.001) and abnormal liver enzymes ( P < 0.01). Compared with lower lipase levels (<3 × ULN), patients with elevated lipase had higher rates of ICU admission (92.9% vs 32.8%; P < 0.001) and intubation (78.6% vs 23.5%; P 0.002). In a multivariable-adjusted model, higher lipase levels were significantly associated with admission to the ICU and rate of intubation. DISCUSSION: Lipase elevation is seen in COVID-19 and is associated with worse disease outcomes.

Background Gastric variceal bleeding carries significant mortality in the setting of portal hypertension. Among the endoscopic treatment options, endoscopic ultrasound (EUS)-guided glue and/or coil injection is a novel approach, but its role in the treatment of gastric varices is not established due to a lack of robust data. Methods We conducted a comprehensive search of several databases (inception to June 2019) to identify studies evaluating EUS in the treatment of gastric varices. Our primary goals were to estimate the pooled rates of treatment efficacy, obliteration and recurrence of gastric varices, early and late rebleeding, and adverse events with EUS-guided therapy in gastric varices. We also searched for studies that evaluated direct endoscopic glue (END-glue) injection for treatment of gastric varices, and used the pooled rates as comparators. Results 23 studies (851 patients) evaluating EUS-guided therapy were included. The pooled treatment efficacy was 93.7 % (95 % confidence interval [CI] 89.5 – 96.3, I 2 = 53.7), gastric varices obliteration was 84.4 % (95 %CI 74.8 – 90.9, I 2 = 77), gastric varices recurrence was 9.1 % (95 %CI 5.2 – 15.7, I 2 = 32), early rebleeding was 7.0 % (95 %CI 4.6 – 10.7, I 2 = 0), and late rebleeding was 11.6 % (95 %CI 8.8 – 15.1, I 2 = 22). The rates were comparable to END-glue therapy (28 studies, 3467 patients) except for obliteration, which was significantly better with EUS-guided therapy. On subgroup analysis, EUS-coil/glue combination showed superior outcomes. Conclusions EUS-guided therapy demonstrated clinical efficacy for treatment of gastric varices in terms of obliteration, recurrence, and long-term rebleeding, and may be superior to END-glue.

Background Peroral endoscopic myotomy (POEM) is increasingly being used as the endoscopic treatment option for achalasia. Data are limited as to the comparative efficacy of anterior vs. posterior myotomy. Methods We searched multiple databases from inception to August 2019 to identify studies reporting on POEM. We selected studies that reported on the outcomes of POEM, along with information on myotomy approach. We performed a comparative analysis of clinical success, gastroesophageal reflux disease (GERD), and adverse events with anterior and posterior myotomy in POEM by meta-analysis. Results 1247 patients from 18 studies were analyzed: 623 patients (11 cohorts) were treated via anterior myotomy and 624 patients (12 cohorts) via posterior myotomy. The pooled rate for clinical success gave an odds ratio (OR) of 1.02 (95 % confidence interval [CI] 0.52 – 2.0; I 2 0; P = 0.9); for GERD by esophagogastroduodenoscopy (EGD) was OR 1.02 (95 %CI 0.62 – 1.68; I 2 0; P = 0.9), and for GERD by pH was OR 0.98 (95 %CI 0.59 – 1.63; I 2 34; P = 0.9). The individual pooled rates of clinical success at 12 months and > 12 months, GERD (by symptoms, EGD, pH), and adverse events (mild, moderate, severe) were comparable. The pooled total procedure time with anterior myotomy was 82.7 minutes (95 %CI 69.0 – 96.4; I 2 98) and with posterior myotomy was 62.1 minutes (95 %CI 48.5 – 75.7; I 2 90). Conclusion Anterior and posterior myotomy in POEM seem comparable to each other in terms of clinical success, GERD, and adverse events. The total procedure time with posterior myotomy seems to be shorter than with anterior myotomy.

Coronavirus disease 2019 (COVID-19) has taken hundreds of thousands of lives globally. Besides the respiratory tract, the virus can affect the gastrointestinal (GI) tract. Data regarding the significance of GI symptoms in the COVID-19 course are limited. In this largest US study to date, the authors reviewed electronic encounters of 1003 consecutive patients who were tested positive for the virus between March 12 and April 3, 2020. Initial GI symptoms were present in up to 22.4% of patients and were associated with worse outcomes after adjustment for demographics, comorbidities, and other clinical symptoms. COVID-19 with GI involvement may define a more severe phenotype.

Background: Endogenous endophthalmitis (EE) is a devastating complication that develops as a metastatic infection in patients with Klebsiella pneumoniae pyogenic liver abscess (KPPLA). The existing data are heterogeneous and the actual disease burden and risk factors for the development of EE among patients with KPPLA have not been systematically examined. We performed a systematic review and meta-analysis to examine the incidence of EE, temporal trend of EE, and risk factors for EE in patients with KPPLA. Methodology: The MEDLINE, EMBASE, Web of Science, and Cochrane Library databases were searched for articles published from inception to 2020 that evaluated the incidence of EE among patients with KPPLA. By a random-effects method, a pooled estimate of its incidence with 95% confidence intervals was estimated along with examination of its temporal and geographic variations. Pooled odds ratios were calculated for risk factors. Results: Fifteen retrospective studies reporting data on 11889 patients with KPPLA met the inclusion criteria and were analyzed. With 217 patients developing EE, the pooled incidence of EE was 4.5% (95% confidence interval 2.4% to 8.2%). The heterogeneity was considerable and significant (Cochran's Q 243.5, p < 0.001, I 2 = 94.2%). Conclusion:This meta-analysis estimates the actual incidence of EE among patients with KPPLA, where EE is reported in about 1 of 22 patients with KPPLA. Infection caused by K1 capsular serotype was an independent risk factor.
