Comparison of big funnel and individualized stents for management of stomach cancer with gastric outlet obstruction.

ABSTRACT:

Background

Previous studies reported a similar rate of complications, including stent migration and obstruction, between individualized stents and the standard uncovered stents in gastric outlet obstruction (GOO) caused by distal stomach cancer. The objective of this study was to evaluate the efficacy and safety of funnel stents for management of GOO caused by distal stomach cancer.

Methods

This study was designed as a multicenter, controlled, prospective, and randomized clinical trial involving 4 hospitals. The individualized stent group (44 cases) received cup and funnel covered stents, and the funnel group (44 cases) received only funnel covered stents for management of GOO caused by distal gastric cancer.

Results

All patients with GOO were treated with cup and funnel stents according to their assigned groups. The rate of GOO resolution was 100% in the funnel group and 97.7% in the individualized stent group. Stent obstruction caused by tumor ingrowth was observed in 1 patient in the individualized stent group, and proximal partial stent migration was observed in 1 patient in each group. Stent obstruction caused by tumor ingrowth was observed in 1 patient in the individualized stent group. There was no statistical difference in stent migration, obstruction, and survival between groups.

Conclusion

Big funnel stents and individualized stents resulted in similar shaping effect and prevention of stent migration and obstruction, suggesting that funnel shaped stents can be used to treat cup or funnel shaped GOO caused by distal stomach cancer.

Project description:BACKGROUND:Gastric outlet obstruction (GOO) is one of the main complications in stage IV gastric cancer patients. This condition is usually managed by gastrojejunostomy (GJ). However, gastric partitioning (GP) has been described as an alternative to overcoming possible drawbacks of GJ, such as delayed gastric emptying and tumor bleeding. AIM:To compare the outcomes of patients who underwent GP and GJ for malignant GOO. METHODS:We retrospectively analyzed 60 patients who underwent palliative gastric bypass for unresectable distal gastric cancer with GOO from 2009 to 2018. Baseline clinicopathological characteristics including age, nutritional status, body mass index, and performance status were evaluated. Obstructive symptoms were graded according to GOO score (GOOS). Surgical outcomes evaluated included duration of the procedure, surgical complications, mortality, and length of hospital stay. Acceptance of oral diet after the procedure, weight gain, and overall survival were the long-term outcomes evaluated. RESULTS:GP was performed in 30 patients and conventional GJ in the other 30 patients. The mean follow-up was 9.2 mo. Forty-nine (81.6%) patients died during that period. All variables were similar between groups, with the exception of worse performance status in GP patients. The mean operative time was higher in the GP group (161.2 vs 85.2 min, P < 0.001). There were no differences in postoperative complications and surgical mortality between groups. The median overall survival was 7 and 8.4 mo for the GP and GJ groups, respectively (P = 0.610). The oral acceptance of soft solids (GOOS 2) and low residue or full diet (GOOS 3) were reached by 28 (93.3%) GP patients and 22 (75.9%) GJ patients (P = 0.080). Multivariate analysis demonstrated that GOOS 2 and GOOS 3 were the main prognostic factors for survival (hazard ratio: 8.90, 95% confidence interval: 3.38-23.43, P < 0.001). CONCLUSION:GP is a safe and effective procedure to treat GOO. Compared to GJ, it provides similar surgical outcomes with a trend to better solid diet acceptance by patients.

Project description:ObjectivesCombined biliary obstruction and gastric outlet obstruction (GOO) represent a challenging clinical scenario despite developments in therapeutic endoscopic ultrasonography (EUS) as GOO might impair EUS-guided biliary drainage. Little is known about the effectiveness of different therapeutic combinations used to treat double obstruction, especially regarding stent patency.MethodsAll consecutive patients with double obstruction treated between 2016 and 2021 in three tertiary academic centres were eligible for inclusion. Five combinations involving enteral stenting (ES), EUS-guided gastroenterostomy (EUS-GE), hepaticogastrostomy (EUS-HGS), choledochoduodenostomy (EUS-CDS), and transpapillary biliary stenting (TPS) were evaluated for dysfunction during follow-up, either as proportions or dysfunction-free survival (DFS) using Kaplan-Meier estimates.ResultsNinety-three patients were included (male 46%; age 67 [interquartile range 60-76] years; pancreatic cancer 73%, metastatic 57%), resulting in 103 procedure combinations. Different combinations showed significantly different overall dysfunction rates (p = 0.009), ranging from the null rate of EUS-GE+HG to the 18% rate of EUS-GE+TPS, 31% of EUS-GE+EUS-CD, 53% of ES+TPS and 83% of ES+EUS-CDS. Sub-analyses restricted to biliary dysfunction confirmed these trends. A multivariate Cox proportional-hazards regression of DFS, a stenosis distal to the papilla (HR 3.2 [1.5-6.9]) and ES+EUS-CDS (HR 5.6 [2-15.7]) independently predicted dysfunction.ConclusionsDespite a lack of statistical power per combination, this study introduces new associations beyond the increased risk of GOO recurrence with ES versus EUS-GE. EUS-CDS showed reduced effectiveness and frequent dysfunction in the context of GOO, especially when combined with ES. EUS-GE+HGS or EUS-GE+TPS in this setting might result in superior patency. These results suggest that a prospective evaluation of the optimal endoscopic approach to malignant double obstruction is needed.
