Background Endoscopic duodenal stenting is the current standard treatment for malignant gastric outlet obstruction (GOO) in patients with limited life expectancy. However, duodenal stenting is prone to stent dysfunction. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is a novel technique with potentially superior stent patency. We compared clinical success, safety, and stent dysfunction of EUS-GE and duodenal stenting in patients with malignant GOO using propensity score matching. Methods This international, multicenter, retrospective study analyzed consecutive patients undergoing EUS-GE or duodenal stenting for GOO between 2015 and 2021 in three European centers. Primary outcomes were clinical success (GOO scoring system [GOOSS] ≥ 2) and stent dysfunction (GOOSS ≤ 1 after initial clinical success). A propensity score matching (1:1) analysis was performed using age, sex, underlying disease, disease stage, ascites, and peritoneal carcinomatosis as variables. Results 214 patients underwent EUS-GE (n = 107) or duodenal stenting (n = 107). After propensity score matching, 176 patients were matched and compared. Technical success rates for EUS-GE and duodenal stenting were 94 % (95 %CI 89 %–99 %) vs. 98 % (95 %CI 95 %–100 %), respectively (P = 0.44). Clinical success rates were 91 % (95 %CI 85 %–97 %) vs. 75 % (95 %CI 66 %–84 %; P = 0.008). Stent dysfunction occurred in 1 % (95 %CI 0–4 %) vs. 26 % (95 %CI 15 %–37 %) of patients (P < 0.001). Adverse event rate was 10 % (95 %CI 4 %–17 %) vs. 21 % (95 %CI 12 %–29 %; P = 0.09). Conclusion EUS-GE had higher clinical success and lower stent dysfunction, with similar safety, compared with duodenal stenting, suggesting that EUS-GE may be preferred over duodenal stenting in patients with malignant GOO.
Background: Endoscopic treatment of post-esophagectomy/gastrectomy anastomotic dehiscence includes Self-Expandable Metal Stents (SEMS), which have represented the “gold standard” for many years, and Endoscopic Vacuum Therapy (EVT), which was recently introduced, showing promising results. The aim of the study was to compare outcomes of SEMS and EVT in the treatment of post-esophagectomy/gastrectomy anastomotic leaks, focusing on oncologic surgery. Methods: A systematic search was performed on Pubmed and Embase, identifying studies comparing EVT versus SEMS for the treatment of leaks after upper gastro-intestinal surgery for malignant or benign pathologies. The primary outcome was the rate of successful leak closure. A meta-analysis was conducted, performing an a priori-defined subgroup analysis for the oncologic surgery group. Results: Eight retrospective studies with 357 patients were eligible. Overall, the EVT group showed a higher success rate (odd ratio [OR] 2.58, 95% CI 1.43–4.66), a lower number of devices (pooled mean difference [pmd] 4.90, 95% CI 3.08–6.71), shorter treatment duration (pmd −9.18, 95% CI −17.05- −1.32), lower short-term complication (OR 0.35, 95% CI 0.18–0.71) and mortality rates (OR 0.47, 95% CI 0.24–0.92) compared to stenting. In the oncologic surgery subgroup analysis, no differences in the success rate were found (OR 1.59, 95% CI 0.74–3.40, I2 = 0%). Conclusions: Overall, EVT has been revealed to be more effective and less burdened by complications compared to stenting. In the oncologic surgery subgroup analysis, efficacy rates were similar between the two groups. Further prospective data need to define a unique management algorithm for anastomotic leaks.
We found out that being nonagenarian, compared to octogenarian, is not a significant risk factor in terms of LOS and in-hospital mortality within 30 days postoperatively. Despite that, the mortality rate among nonagenarians is still remarkably high as almost every patient was admitted in an emergent setting. The most remarkable predictor for mortality among the two groups was an "afternoon/night emergency" surgical presentation (OR 25.5, CI 1.53-42.35, p = 0.02). Thus, the surgical emergency management for gallbladder disease at our institution should be critically reevaluated. Performing the procedure in laparoscopy predicted a significant reduction (-5 days, CI -8.5 to -1.4, p = 0.006) of LOS, while presenting with "gallbladder and bile duct stones" (+6.3 days, CI 1.5-11.1, p = 0.01) or "acalculous cholecystitis" (+4.7 days, CI 0.4-9.2, p = 0.03) had the opposite effect. Despite the remarkable mortality rate of our series, being nonagenarian should not be considered as a reason to avoid gallbladder surgery in case of need. Our study suggests that nonagenarians are more suitable surgical candidates than may have previously expected.
