Early versus late drainage of pancreatic necrotic fluid collections: a systematic review and meta-analysis.

Background: Necrotizing pancreatitis can be complicated by necrotic fluid collections (NFCs). International guidelines recommend waiting 4 weeks for the collection to mature before interventional management. With the advances in endoscopic drainage, the need to delay drainage by 4 weeks is unclear.

EUS-guided therapies for primary and secondary prophylaxis in gastric varices-An updated systematic review and meta-analysis.

Background And Objectives: Gastric varices (GVs) are associated with a higher risk of uncontrolled bleeding and death when compared with esophageal varices. While endoscopic glue injection therapy has been traditionally used for secondary prophylaxis in GV, data regarding primary prophylaxis continue to emerge. Recently, EUS-guided therapies have been used in GV bleeding.

Fecal microbiota transplant delivered via invasive routes in irritable bowel syndrome: A systematic review and meta-analysis of randomized controlled trials.

Background And Aims: Irritable bowel syndrome (IBS) results in significant loss of quality of life. Management guidelines do not recommend fecal microbiota transplant (FMT) for IBS based on weak evidence as refined data is lacking. We performed a systematic review and meta-analysis to ascertain the pooled clinical outcomes of FMT in IBS, delivered via invasive routes.

Cap-assisted endoscopic treatment of esophageal food bolus impaction and/or foreign body ingestion: a systematic review and meta-analysis.

Background: Esophageal food bolus and/or foreign body (FB) impaction is a common gastrointestinal emergency. This meta-analysis reports on the pooled outcomes of cap-assisted endoscopic removal of esophageal FB.

Methods: We conducted a comprehensive search of several databases (inception to February 2022) to identify studies reporting on the use of a cap in the endoscopic treatment of esophageal FB ingestion.

Responses to mechanically and visually cued water waves in the nervous system of the medicinal leech.

Sensitivity to water waves is a key modality by which aquatic predators can detect and localize their prey. For one such predator - the medicinal leech, - behavioral responses to visual and mechanical cues from water waves are well documented. Here, we quantitatively characterized the response patterns of a multisensory interneuron, the S cell, to mechanically and visually cued water waves.

Endoscopic submucosal dissection of gastric tumors: A systematic review and meta-analysis.

Aim: To systematically review the medical literature in order to evaluate the safety and efficacy of gastric endoscopic submucosal dissection (ESD).

Methods: We performed a comprehensive literature search of MEDLINE, Ovid, CINAHL, and Cochrane for studies reporting on the clinical efficacy and safety profile of gastric ESD.

Results: Twenty-nine thousand five hundred and six tumors in 27155 patients (31% female) who underwent gastric ESD between 1999 and 2014 were included in this study.
