Background/aims: Helicobacter pylori infection has been implicated in atrophic gastritis and gastric ulcer disease. However, the relationship between gastric emptying and Helicobacter pylori infection is still unclear.
Methodology: One hundred and two consecutive patients with functional dyspepsia were enrolled in this study (53 Helicobacter pylori positive and 49 negative). Gastric emptying was determined using both the 13C-octanoic acid breath test and the paracetamol absorption test. For grading gastric atrophy, the biopsy samples and serum pepsinogen I/II ratio were used. The relationship between gastric emptying, Helicobacter pylori infection and atrophy grade was investigated.
Results: There was no significant difference in all gastric emptying parameters between Helicobacter pylori positive and negative patients. However, in Helicobacter pylori positive subjects, pepsinogen I/II ratio correlated with atrophy grade, and it also correlated with all parameters of gastric emptying. Especially in the half-emptying time, an important parameter, there was significant correlation with the pepsinogen I/II ratio (R = -0.39, p < 0.01). This finding implies that gastric emptying is delayed according to the degree of gastric atrophy.
Conclusions: Gastric emptying was not delayed simply according to advanced age, but according to the advance in gastric atrophy.

Ultrasound evaluation of gastric emptying for two different quantities of milk in elementary school-aged children.

Unlabelled: Current guidelines recommend 6-h milk fasting in periprocedural settings; however, recent evidence suggests potential overconservativeness and supports more liberal pediatric fasting protocols. This study assessed the gastric emptying of two different milk quantities in elementary school-age children using gastric ultrasonography. This prospective crossover trial involved 30 healthy children who fasted overnight on two separate occasions within one month, consuming either 5 or 10 mL/kg of milk.

The presence of an aberrant right hepatic artery (a-RHA) could influence the oncological and postoperative outcomes after pancreaticoduodenectomy (PD). A comparative study was conducted, including patients who underwent PD with a-RHA or with normal RHA anatomy. The primary endpoints were R1 resection in all margins (pancreatic, anterior, posterior, superior mesenteric artery, and portal groove), overall survival (OS), and disease-free survival (DFS).

Background: Minimally invasive pancreatoduodenectomy has gained widespread acceptance among hepatopancreatobiliary surgeons due to its demonstrated advantages in perioperative outcomes compared to the conventional open approach. This meta-analysis, along with trial sequential analysis, aimed to compare the outcomes of robotic pancreatoduodenectomy and laparoscopic pancreatoduodenectomy based on the current available evidence.
Methods: A systematic search of PubMed, Cochrane, Scopus, and Web of Science was conducted from inception to July 2024.

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.

Sleep deficiency is associated with obesity, but the mechanisms underlying this connection remain unclear. Here, we identify a sleep-inducible hypothalamic protein hormone in humans and mice that suppresses obesity. This hormone is cleaved from reticulocalbin-2 (RCN2), and we name it Raptin.
