Is there a place for endoscopic management in post-cholecystectomy iatrogenic bile duct injuries?

In this editorial we comment on the article by Emara et al published in the recent issue of the World Journal of Gastrointestinal Surgery. Previously, surgery was the primary treatment for bile duct injuries (BDI). The treatment of BDI has advanced due to technological breakthroughs and minimally invasive procedures. Endoscopic and percutaneous treatments have largely supplanted surgery as the primary treatment for most instances in recent years. Patient management, including the specific technique, is typically impacted by local knowledge and the kind and severity of the injury. Endoscopic therapy is a highly successful treatment for postoperative benign bile duct stenosis and offers superior long-term outcomes compared to surgical correction. Based on the damage features of BDI, therapeutic options include endoscopic duodenal papillary sphincterotomy, endoscopic nasobiliary drainage, and endoscopic biliary stent implantation.

Mutational landscape of TP53 and CDH1 in gastric cancer.

In this editorial we comment on an article published in a recent issue of the World J Gastrointest Surg. A common gene mutation in gastric cancer (GC) is the TP53 mutation. As a tumor suppressor gene, TP53 is implicated in more than half of all tumor occurrences. TP53 gene mutations in GC tissue may be related with clinical pathological aspects. The TP53 mutation arose late in the progression of GC and aided in the final switch to malignancy. CDH1 encodes E-cadherin, which is involved in cell-to-cell adhesion, epithelial structure maintenance, cell polarity, differentiation, and intracellular signaling pathway modulation. CDH1 mutations and functional loss can result in diffuse GC, and CDH1 mutations can serve as independent prognostic indicators for poor prognosis. GC patients can benefit from genetic counseling and testing for CDH1 mutations. Demethylation therapy may assist to postpone the onset and progression of GC. The investigation of TP53 and CDH1 gene mutations in GC allows for the investigation of the relationship between these two gene mutations, as well as providing some basis for evaluating the prognosis of GC patients.
