Introduction: Heterotopic pancreas, also known as ectopic pancreas, is defined as the presence of pancreatic tissue outside its normal location and without anatomic and vascular continuity with the main body of the pancreas. The incidence of heterotopic pancreas has been reported as 0.5 % during laparotomies and at autopsy ranging from 0.6–14 %. Presentation of case: A 28 years old obese male, medically free electively admitted for laparoscopic sleeve gastrectomy. Intraoperatively after dissecting the greater omentum from the stomach and inserting the 36 Fr gastric bougie, small oval shape mass about 1 cm close to the lesser curvature on the anterior surface of the gastric antrum. Macroscopically benign looking and a thorough laparoscopic exploration showed no signs of other organs involvement. Antrectomy and mini gastric bypass done. The postoperative course was uneventful. The histopathological examination of the antrectomy specimen showed heterotopic pancreas in the subserosa of gastric antrum. Discussion: The Heterotopic pancreatic tissue can be discovered in the stomach (particularly antrum), duodenum, jejunum, or a Meckel diverticulum. Surgical resection is the mainstay treatment if the heterotopic pancreas is symptomatic or when the lesion is found incidentally during surgery in order to prevent complications. Conclusion: Heterotopic pancreas should always be considered in the differential diagnosis of incidentally found gastric lesions and can be safely resected. This is the first case report of gastric heterotopic pancreas which is found incidentally during a bariatric surgery procedure. Highlights:

(1) Background: This study aims to identify the sociodemographic, behavioural, and systemic predictors of colorectal cancer (CRC) screening among primary healthcare attendees in Riyadh, Saudi Arabia, to inform targeted interventions and policy strategies. (2) Methods: This cross-sectional study was conducted between March and July 2023 across 48 randomly selected primary healthcare centers in Riyadh, Saudi Arabia. The target population for this study was adults aged 18 and above attending primary healthcare centers in Riyadh. Multi-stage random sampling was used to recruit participants. Multivariate logistic regression was performed to identify independent predictors of CRC screening. (3) Results: CRC screening uptake was found to be only 4.2%. Age was a significant predictor, with individuals aged 50–75 years (adjusted odds ratio [AOR]: 1.90, 95% confidence interval [CI]: 1.50–2.42) and those aged 75 years or older (AOR: 1.37, 95% CI: 1.01–1.87) being more likely to undergo screening compared to younger individuals. Insurance coverage strongly influenced screening behaviour (AOR: 1.64, 95% CI: 1.37–1.96). Smokers were nearly four times more likely to participate in screening than non-smokers (AOR: 3.87, 95% CI: 3.21–4.69), and physical activity was positively associated with screening (AOR: 1.43, 95% CI: 1.11–1.82). (4) Conclusions: CRC screening uptake in Riyadh is critically low, highlighting the need for targeted public health interventions. Key predictors such as age, insurance coverage, smoking, and physical activity underscore the importance of addressing sociodemographic disparities and promoting health awareness. The findings emphasize the need for culturally tailored educational campaigns, improved healthcare access, and enhanced screening programs to increase uptake.

Climate change will have a great impact on humanity in upcoming years and will affect the health of all living creatures. Hospitals play a significant role in climate change due to their substantial waste production and they are considered a profound pollution source, with the Operating Theater as a main contributor. This study was aimed to examine the level of knowledge among healthcare professionals in Saudi Arabia concerning the proper implementation of operating room (OR) environmental procedures and efficient management of hospital waste. This is a cross sectional study performed across 3 hospitals in Riyadh, Saudi Arabia. The hospitals included are Prince Sultan military hospital, National guard hospital and King Salman hospital. The study included all the staff and health workers in OR (operating room), excluding all staff and health workers not in OR. The study took place between September 1 and November 1, 2022. None of the study participants mentioned that their institute or hospital fully engaged in Greenhealth Greening the OR initiative. Almost 1 to 3rd of the study participants (38.1%) mentioned that endorsement and participation in the practice of Greenhealth Greening the OR initiative was not implemented at all, and 45% of the participants were completely unaware of such an initiative. The study’s findings suggest that healthcare providers in Saudi Arabia are not fully aware of environmentally friendly practices. Further, the current initiatives undertaken by the hospital administration fall short in attaining environmentally sustainable benchmarks.

Background: Anastomotic leak (AL) is a serious complication after gastrectomy. It is associated with prolonged hospital stay, greater expenses, and increased risk for 90-day mortality. Currently, there is no consensus regarding the effect of AL on OS in patients with GC undergoing gastrectomy. This study was designed to investigate the effect of AL on long-term survival after gastrectomy for gastric cancer. Methods: PubMed, Embase, Scopus, Google Scholar, and Cochrane Library were queried during the search process. The literature search started in January 2025 and was updated in May 2025. The studies analyzed the impact of AL on long-term survival, with the primary outcome being long-term overall survival. Pooled effect size measures included restricted mean survival time difference (RMSTD), hazard ratio (HR), and 95% confidence intervals (CIs). Results: Ten studies (11,862 patients) were included. Overall, 338 (2.9%) patients experienced AL. The RMSTD analysis indicates that at 12, 24, 36, 48, and 60 months, patients with AL tend to live 1.1, 3.1, 5.2, 8.1, and 10.6 months shorter, respectively, compared to those who did not develop AL. All results were statistically significant with p < 0.0001. The time-dependent HRs analysis for AL versus no AL shows a higher mortality hazard in patients with AL at 12 (HR 1.32, 95% CI 1.11–1.58), 24 (HR 1.61, 95% CI 1.34–1.92), 36 (HR 1.55, 95% CI 1.27–1.91), 48 months (HR 1.22, 95% CI 1.02–1.53), and 60 months (HR 0.79, 95% CI 0.59–1.10). Conclusions: This research appears to indicate a clinical impact of AL on long-term OS after gastrectomy. Patients experiencing AL appear to have an increased risk of mortality within the initial four years of follow-up.

Introduction: Cholecystogastric fistula is an abnormal communication between the gallbladder and the stomach, it is a rare complication of chronic cholethiasis. Preoperative diagnosis is difficult as patients often present with non-specific symptoms. Case presentation: A 63-year-old female presented to the outpatient clinic with symptomatic cholelithiasis. Physical examination was unremarkable. Laboratory investigations, including complete blood count (CBC) and liver function test (LFT), were within normal limits. Upper abdominal ultrasound revealed hepatomegaly and gallbladder contraction with multiple gallstones. Intraoperative exploration during laparoscopic cholecystectomy revealed adhesions with cholecystogastric fistula, necessitating meticulous dissection, fistula excision, and primary closure. Postoperatively, the patient recovered uneventfully, with a negative methylene blue leak test allowing early oral intake. Discharged home in stable condition, subsequent follow-up showed resolution of symptoms, and histopathological examination confirmed absence of neoplastic changes. Discussion: Optimal surgical management of cholecystogastric fistula is debatable, laparoscopic surgery have led to improved outcomes in the management of these cases. Utilizing which approach should be determined based on the clinical scenario for each patient and the surgeon experience. Conclusion: Cholecystogastric fistula is a rare complication of chronic cholethiasis. Preoperative diagnosis requires high index of suspicion. Complete laparoscopic management is safe. Highlights:
