Clinical outcomes of endoscopic submucosal dissection for superficial esophageal neoplasia in close proximity to esophageal varices: a multicenter international experience

Endoscopic resection of early esophageal neoplasia in patients with esophageal varices: a systematic review

Although endoscopic resection (ER) is recommended as first-choice treatment for early esophageal neoplasia, patients with esophageal varices are considered a high-risk group owing to an increased risk of bleeding. This systematic review aimed to evaluate the effectiveness and safety of ER in this specific patient category.We searched for studies reporting on clinical outcomes of ER in the presence of esophageal varices, irrespective of study design or follow-up time. End points included the incidence of prophylactic measures to reduce the risk of variceal hemorrhage, radical and curative resection rates, and adverse events.After screening 2371 studies, 42 studies (including our own unpublished cohort) with a total of 186 patients were included in this systematic review. Endoscopic band ligation (72/186; 39%) and endoscopic injection sclerotherapy (22/186; 12%) were the prophylactic measures most widely adopted to eradicate varices prior to ER. Other frequently described prophylactic measures included direct varix coagulation during ER (18/186; 10%) and the placement of a transjugular intrahepatic portosystemic shunt prior to ER (9/186; 5%). While the radical and curative resection rates were high (86% and 72%, respectively), the periprocedural and delayed bleeding risks were reported to be relatively low (6% and 3%, respectively). In all studies, no procedure-related mortality was observed.ER appeared to be a safe and effective treatment option in selected patients with concurrent early esophageal neoplasia and esophageal varices, provided that a tailored approach of adequate prophylactic measures to prevent bleeding is applied.

Comparative efficacy of endoscopic variceal ligation versus non-selective beta-blockers in primary prevention of gastroesophageal varix type 2: an IPTW-adjusted study

BACKGROUND

Practice guidelines recommend non-selective beta-blockers (NSBB) and endoscopic variceal ligation (EVL) for primary prevention in cirrhosis patients with esophageal varices. However, there is no clear recommendation for primary prevention strategies for gastric varices, particularly GOV-2. Our objective is to investigate the incidence of initial bleeding and liver-related complications when NSBB and EVL are used for primary prevention in GOV-2.

METHODS

A retrospective analysis was conducted on data from patients with GOV-2 gastric varices. Patients were divided into the NSBB group or the EVL group. Differences in the incidence of initial bleeding within 1 year, as well as the occurrence of complications such as hepatic encephalopathy and ascites, were compared between the two groups before and after adjustment for Inverse Probability of Treatment Weighting (IPTW). A Cox proportional hazards model was used to identify independent risk factors for the first bleeding event.

RESULTS

There were 60 patients in the NSBB group and 66 patients in the EVL group. Before IPTW adjustment, there were differences between the two groups in sex, portal hypertensive gastropathy, esophageal variceal diameter, red signs, FIB-4, and MELD scores. After IPTW adjustment, these differences were balanced, with standardized mean differences (SMDs) within acceptable ranges. Kaplan-Meier survival analysis showed no difference in bleeding rates between the two groups before or after IPTW adjustment. After IPTW adjustment, Cox regression analysis identified esophageal variceal diameter (HR:5.59 (2.03-15.39), p < 0.001) and MELD score (HR:1.17 (1.01-1.23), p = 0.042) were independent risk factors for bleeding. NSBB treatment did not reduce the incidence of liver-related complications within one year compared to EVL.

CONCLUSION

For primary prevention of bleeding in cirrhotic patients with GOV-2, EVL does not significantly reduce initial bleeding episodes or liver-related complications compared to NSBB.
