Acute blood loss evoked an increase in the spike activity of the pyloric sphincter' smooth muscles, those of the duodenum and ileum. No such effect was found in joint blockade of alpha- and beta-adrenoreceptors. The increase in the spike activity seems to be due to an effect of endogenous catecholamines upon activating alpha- and beta-adrenoreceptors of the pyloric sphincter, duodenum and ileum.

Objective: To identify strategies to prevent and treat delayed gastric emptying (DGE) after pancreatic surgery.
Background: Among all complications of pancreatic surgery, DGE has the largest impact on prolonged hospital stay. Several randomized controlled trials (RCTs) have addressed DGE after pancreatic surgery, either as primary or as secondary outcome.

The stomach is responsible for physically and chemically processing the ingested meal before controlled emptying into the duodenum through the pyloric sphincter. An incompetent pylorus allows reflux from the duodenum back into the stomach, and if the amount of reflux is large enough, it could alter the low pH environment of the stomach and erode the mucosal lining of the lumen. In some cases, the regurgitated contents can also reach the esophagus leading to additional complications.

Introduction: Endoscopic resection is suitable for most benign gastric or early stage cancerous polyps. Laparoscopic local resection is performed only for gastric polyps that are difficult to treat with endoscopic resection, such as recurrent or large polyps. However, when polyps are located in difficult regions, such as the gastric cardia and prepyloric antrum, wedge resection may damage the sphincter around the cardia or pylorus, resulting in postoperative deformity or stenosis.

(1) Background: The modified Whipple procedure, or pylorus-preserving pancreaticoduodenectomy, is a complex surgical intervention used to treat pancreatic head tumors. While preserving digestive function, it is associated with significant perioperative risks. This study explores the clinical, immunological, and microbiome-related factors influencing postoperative complications, focusing on the interplay between patient comorbidities, systemic inflammation, and gut dysbiosis.
