Antegrade jejunogastric intussusception and common bile duct stones at 14 months after gastrectomy and cholecystectomy: A case report

Association between history of cholecystectomy and risk of gastric cancer: a meta-analysis of epidemiological studies

PURPOSE

Evidence from previous studies on the association between cholecystectomy and risk of gastric cancer are still inconsistent. We aimed at conducting a meta-analysis of epidemiological studies to evaluate this association.

METHODS

Researchers searched three databases (PubMed, Embase and Web of Science) through January 2021 for eligible studies. Relative risks (RRs) and 95% CIs in each included studies were pooled by random-effects models. Patients and the public were not involved in our study.

RESULTS

Eight studies were identified. Four studies reported significantly positive association between history of cholecystectomy and risk of gastric cancer, and the remaining studies reported null association. The pooled RR of these eight studies showed that a history of cholecystectomy was associated with a 11% higher risk of gastric cancer (pooled RR=1.11, 95% CI: 1.03 to 1.20). Moderate heterogeneity across the studies was detected (p=0.117, I2=37.8%). The pooled RRs were 1.12 (95% CI: 1.01 to 1.24) for five cohort studies and 0.95 (95% CI: 0.66 to 1.38) for three case-control studies. Compared with the risk in Europe and the USA, the pooled RR was higher for two studies conducted in Asia. Six studies were assessed as high-quality studies with the pooled RR of 1.12 (95% CI: 1.02 to 1.23). The pooled results were robust by sensitivity analyses, and no indication of publication bias was detected.

CONCLUSION

This meta-analysis suggests that a history of cholecystectomy may be associated with an increased risk of gastric cancer.

Intussusception after reconstruction following gastrectomy for gastric cancer

Background

Gastric cancer is the most prevalent tumor in Chinese men, and surgery is currently the most important treatment. Billroth II and Roux-en-Y are the anastomosis methods used for reconstruction after gastrectomy. Jejunal intussusception is a rare complication after gastric surgery.

Main Body

Intussusception after gastric surgery occurs mostly at the gastrojejunostomy site for Billroth II reconstruction, and the Y-anastomosis site for Roux-en-Y reconstruction. Many studies have reported that postoperative intussusception appears at the anastomosis after bariatric surgery, while a few have reported intussusception at the anastomosis and its distal end after radical gastrectomy.

Conclusion

A review was carried out to analyze intussusception after radical gastrectomy with roux-en-y anastomosis during the current situation. And the relevant mechanisms, diagnosis, treatment methods, etc. are described, hoping to provide better guidance for clinicians
