Short-Term and Long-Term Outcomes of Liver Cirrhosis in Gastric Neoplasm Patients Undergoing Endoscopic Submucosal Dissection.

Purpose: The purpose of this study was to explore whether liver cirrhosis (LC) influences short-term and long-term outcomes in gastric neoplasm patients who undergo endoscopic submucosal dissection (ESD). Materials and Methods: Eligible studies were identified in three databases, including PubMed, Embase, and the Cochrane Library on December 18, 2022. Clinical characteristics, short-term outcomes, and long-term outcomes were compared between an LC group and a no liver cirrhosis (NLC) group. For continuous variables, the mean difference (MD) and standard deviation (SD) were pooled. For discontinuous variables, raw data from the 2 × 2 tables or odds ratio (OR) and 95% confidence intervals (CIs) were pooled. Forest plots were used to show the results, and a funnel plot was used to evaluate publication bias. Data analyses were performed by STATA SE 16.0 software. Results: Six retrospective studies involving 1616 gastric neoplasm patients were included in the study. Clinical characteristics, including age, gender, location, macroscopic type, invasion depth, differentiation, and ulceration, were found to be not significantly different between the LC group and the NLC group ( P  > .05). Moreover, LC was not a risk factor for short-term outcomes, including operative time (MD = 0.15, 95% CI = -0.02 to 0.32, I 2  = 0.00%, P  = .09), en bloc resection (OR = 0.87, 95% CI = 0.43-1.75, I 2  = 0.00%, P  = .69), R0 resection (OR = 0.77, 95% CI = 0.42-1.43, I 2  = 8.97%, P  = .41), bleeding (OR = 1.10, 95% CI = 0.62-1.93, I 2  = 0.00%, P  = .75), and perforation (OR = 1.62, 95% CI = 0.45-5.84, I 2  = 0.00%, P  = .46). However, gastric cancer patients with LC exhibited a higher recurrence rate (OR = 3.40, 95% CI = 1.09-10.61, I 2  = 0.00%, P  = .04) after ESD. Conclusion: Surgeons performing ESD in gastric neoplasm patients should pay more attention to long-term effects.
