Endoscopic ultrasound-guided gastroenterostomy using an oroenteric catheter-assisted technique: a retrospective analysis

Systematic review of long-term effectiveness of endoscopic gastrojejunostomy in patients presenting with gastric outlet obstruction from periampullary malignancies

BACKGROUND

Recently, endoscopic ultrasound-guided (EUS) gastrojejunostomy (GJ) has emerged as an alternative option to surgical palliation and endoscopic duodenal stenting for malignant gastric outlet obstruction (GOO). Although early success rates are commonly reported with the technique, there is a paucity of data regarding the long-term efficacy of this approach. In this study, we investigated long-term outcomes in patients that underwent EUS-guided GJ for palliation of periampullary malignancies.

METHODS

From a total of 192 studies that were reviewed, 6 studies with a follow-up time frame of a minimum of 5 months were analyzed, totaling 238 patients. Outcome variables included technical success rate, clinical success rate, adverse events, symptom recurrence, and re-intervention rates.

RESULTS

The cohort of 238 patients had a technical success rate of 93.7% and a clinical success rate of 92.9%. A total of 25 patients (10.5%) experienced adverse events associated with EUS-GJ. A total of 14 patients (5.9%) experienced recurrence of GOO symptoms within 5 months. A total of 14 patients (5.9%) underwent re-intervention with the first 5 months.

CONCLUSIONS

This systematic review shows that data are scarce regarding long-term effectiveness of EUS-guided GJ. Even though early success rates have been reported, further studies are needed to focus on long-term efficacy of this approach. Until such studies become available, surgical palliation should continue to be the treatment of choice for patients with malignant GOO with a prolonged life expectancy.

EUS-guided gastroenterostomy for gastric outlet obstruction: a comprehensive meta-analysis

OBJECTIVE

A comprehensive meta-analysis was performed to evaluate the efficacy and safety of endoscopic ultrasound-guided gastroenterostomy (EUS-GE) for benign and malignant gastric outlet obstruction (GOO).

MATERIAL AND METHODS

PubMed, Embase, Web of Science and Cochrane Library were searched to identify relevant studies. The primary outcomes evaluated technical success, clinical success, and adverse events (AEs).

RESULTS

Twenty‑six studies with 1493 patients were included in this meta-analysis. The pooled rates of technical success, clinical success, and overall AEs of EUS-GE were 94.0%, 89.9%, and 13.1%, respectively. Eight studies were included in the subgroup meta-analysis for comparative evaluation of EUS-GE and surgical gastroenterostomy (SGE), while seven studies were for EUS-GE and enteral stenting (ES). Compared with SGE, the pooled odds ratios (ORs) of technical success, clinical success, and overall AEs of EUS-GE were 0.17 (p = .003), 1.42 (p = .40), and 0.15 (p < .00001), respectively. When compared with ES, the above corresponding pooled ORs were 0.55 (p = .11), 2.64 (p < .0001), and 0.41 (p = .01), respectively.

CONCLUSION

Although it is technically challenging, this largest meta-analysis indicates that EUS‑GE has comparable and high technical and clinical success rates and hence a very effective minimally invasive procedure for GOO.

Endoscopic ultrasound guided gastroenterostomy: Technical details updates, clinical outcomes, and adverse events

Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) has been transformed from an innovative technique, into a viable alternative to enteral stenting and surgical gastrointestinal anastomosis for patients with gastric outlet obstruction. Even EUS-GE guided ERCP and EUS-guided gastrointestinal anastomosis for the treatment of afferent loop syndrome have been performed, giving patients more less invasive options. However, EUS-GE is still a technically challenging procedure. In order to improve EUS-GE, several techniques have been reported to improve the technical details. With EUS-GE widely performed, more data about EUS-GE’s clinical outcomes have been reported. The aim of the current review is to describe technical details updates, clinical outcomes, and adverse events of EUS-GE.

Endoscopic ultrasound-guided gastroenterostomy with lumen-apposing metal stents: a retrospective multicentric comparison of wireless and over-the-wire techniques

BACKGROUND

Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) using lumen-apposing metal stents (LAMSs) appears to be effective and safe in gastric outlet obstruction (GOO); however, the EUS-GE procedure is not standardized, with the use of assisted or direct methods still debated. The aim of this study was to compare the outcomes of EUS-GE techniques focusing on an assisted with orointestinal drain wireless endoscopic simplified technique (WEST) and the nonassisted direct technique over a guidewire (DTOG).

METHOD

This was a multicenter European retrospective study involving four tertiary centers. Consecutive patients who underwent EUS-GE for GOO between August 2017 and May 2022 were included. The primary aim was to compare the technical success and adverse event (AE) rates of the different EUS-GE techniques. Clinical success was also analyzed.

RESULTS

71 patients (mean [SD] age 66.2 10 years; 42.3 % men; 80.3 % malignant etiology) were included. Technical success was higher in the WEST group (95.1 % vs. 73.3 %; estimate of relative risk from odds ratio (eRR) 3.2, 95 %CI 0.94-10.9; P = 0.01). The rate of AEs was lower in the WEST group (14.6 % vs. 46.7 %; eRR 2.3, 95 %CI 1.2-4.5; P = 0.007). Clinical success was comparable between the two groups at 1 month (97.5 % vs. 89.3 %). The median follow-up was 5 months (range 1-57).

CONCLUSION

The WEST resulted in a higher technical success rate with fewer AEs, with clinical success comparable with the DTOG. Therefore, the WEST (with an orointestinal drain) should be preferred when performing EUS-GE.

Prospective multicenter assessment of the impact of EUS-guided gastroenterostomy on patient quality of life in unresectable malignant gastric outlet obstruction

BACKGROUND AND AIMS

EUS-guided gastroenterostomy (EUS-GE) is increasingly used for malignant gastric outlet obstruction (GOO) in inoperable patients. However, the impact of EUS-GE on patient quality of life (QoL) has not been evaluated prospectively.

METHODS

Consecutive patients with unresectable malignant GOO who underwent EUS-GE between August 2019 and May 2021 at 4 Spanish centers were prospectively assessed using the European Organization for Research and Treatment of Cancer QoL Questionnaire Core 30 at baseline and 1 month after the procedure. Centralized follow-up by telephone calls was undertaken. The Gastric Outlet Obstruction Scoring System (GOOSS) was used to assess oral intake, defining clinical success as a GOOSS ≥2. Differences between baseline and 30-day QoL scores were assessed using a linear mixed model.

RESULTS

Sixty-four patients were enrolled, 33 (51.6%) men, with a median age of 77.3 years (interquartile range, 65.5-86.5). The most common diagnoses were pancreatic (35.9%) and gastric (31.3%) adenocarcinoma. Thirty-seven patients (57.9%) presented a 2/3 baseline Eastern Cooperative Oncology Group performance status score. Oral intake was restarted within 48 hours in 61 patients (95.3%), and the median postprocedure hospital stay was 3.5 days (interquartile range, 2-5). The 30-day clinical success rate was 83.3%. A clinically significant increase of 21.6 points (95% confidence interval, 11.5-31.7) in the global health status scale was documented, with significant improvements in nausea and vomiting, pain, constipation, and appetite loss.

CONCLUSIONS

EUS-GE relieves GOO symptoms in patients with unresectable malignancy, allowing rapid oral intake and hospital discharge. It also provides a clinically relevant increase in QoL scores at 30 days from baseline. (Clinical trial registration number: NCT04660695.).

No difference in outcomes with 15 mm vs. 20 mm lumen-apposing metal stents for endoscopic ultrasound-guided gastroenterostomy for gastric outlet obstruction: a meta-analysis

BACKGROUND/AIMS

We compared outcomes between use of 15 vs. 20 mm lumen-apposing metal stents (LAMSs) in endoscopic ultrasound-guided gastroenterostomy (EUS-GE) for gastric outlet obstruction.

METHODS

Databases were queried for studies that used LAMS for EUS-GE to relieve gastric outlet obstruction, and a proportional meta-analysis was performed.

RESULTS

Thirteen studies were included. The 15 mm and 20 mm LAMS had pooled technical success rates of 93.2% (95% confidence interval [CI], 90.5%-95.2%) and 92.1% (95% CI, 68.4%-98.4%), clinical success rates of 88.6% (95% CI, 85.4%-91.1%) and 89.6% (95% CI, 79.0%-95.1%), adverse event rates of 11.4% (95% CI, 8.1%-15.9%) and 14.7% (95% CI, 4.4%-39.1%), and reintervention rates of 10.3% (95% CI, 6.7%-15.4%) and 3.5% (95% CI, 1.6%-7.6%), respectively. Subgroup analysis revealed no significant differences in technical success, clinical success, or adverse event rates. An increased need for reintervention was noted in the 15 mm stent group (pooled odds ratio, 3.59; 95% CI, 1.40-9.18; p=0.008).

CONCLUSION

No differences were observed in the technical, clinical, or adverse event rates between 15 and 20 mm LAMS use in EUS-GE. An increased need for reintervention is possible when using a 15 mm stent compared to when using a 20 mm stent.

GIE Editorial Board Top 10: advances in GI endoscopy in 2021

The 9-member Editorial Board of the American Society for Gastrointestinal Endoscopy performed a systematic literature search of original articles published during 2021 in Gastrointestinal Endoscopy and 10 other high-impact medical and gastroenterology journals on endoscopy-related topics. Votes from each editorial board member were tallied to identify a consensus list of the 10 most significant topic areas in GI endoscopy over the calendar year of study, with a focus on 3 criteria: significance, novelty, and global impact on clinical practice. The 10 areas identified collectively represent advances in the following endoscopic topics: colonoscopy optimization, bariatric endoscopy, endoscopic needle sampling and drainage, peroral endoscopic myotomy, endoscopic defect closure, meeting systemic challenges in endoscopic training and practice, endohepatology, FNA versus fine-needle biopsy sampling, endoscopic mucosal and submucosal procedures, and cold snare polypectomy. Each board member contributed a summary of important articles relevant to 1 to 2 of the consensus topic areas, leading to a collective summary that is presented in this document of the "top 10" endoscopic advances of 2021.

Endoscopic Ultrasound-Guided Gastroenterostomy for the Palliation of Gastric Outlet Obstruction (GOO): A Systematic Review and Meta-analysis of the Different Techniques

INTRODUCTION

Gastric outlet obstruction (GOO) is usually associated with a poor prognosis and a significant decrease in a patient's quality of life. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) using lumen-apposing metal stents (LAMS) has emerged as a safe and effective palliation procedure for GOO in patients that are unfit for surgery. Without an exclusive gold-standard technique for EUS-GE, we aimed to compare the currently available ones in this systematic review and meta-analysis, the first on this subspecialty.

METHODS

A comprehensive search from multiple electronic databases was performed. The search had a particular emphasis on the techniques used in performing EUS-GE. We identified all the studies in which EUS-GE was performed as palliation for GOO from its inception to the current date. The outcomes analyzed were the following: technical and clinical success, total and severe adverse events (AEs), procedure duration, and length of hospital stay (LOHS).

RESULTS

Twenty studies involving 863 patients were the basis of this statistical analysis. Patients underwent the following techniques: direct gastroenterostomy (DGE) (n=718), balloon-assisted gastroenterostomy (BAGE) (n=27), and endoscopic ultrasound (EUS)-guided double-balloon-occluded gastrojejunostomy bypass (n=118). In comparison to balloon-assisted techniques, DGE had a lower rate of AEs, -0.121 (95% CI -0.191 to -0.051 p=0.001); and LOHS for the DGE group, -2.684 (95% CI -1.031 to -4.337 p=0.001). The other analyzed outcomes presented no statistically significant differences. On a sub-analysis, BAGE showed a lower rate of AEs than EUS-guided double-balloon-occluded gastrojejunostomy bypass, -0.196 (95% CI -0.061 to -0.331 p=0.004).

CONCLUSIONS

EUS-GE is a safe and effective procedure for palliating GOO. When correctly administered, any of the analyzed techniques may be used to palliate GOO with similar technical and clinical outcomes. DGE had significantly lower rates of AEs and LOHS, which can be inferred as a safer procedure. These results should be interpreted cautiously due to the limited few studies that are available and accessible. Therefore, further well-designed, randomized clinical studies on the topic are warranted to compare the different techniques from more sources.

Hybrid gastroenterostomy using a lumen-apposing metal stent: a case report focusing on misdeployment and systematic review of the current literature

Background

Gastric outlet obstruction can result from several benign and malignant diseases, in particular gastric, duodenal or pancreatic tumors. Surgical gastroenterostomy and enteral endoscopic stenting have represented effective therapeutic options, although recently endoscopic ultrasound-guided gastroenterostomy using lumen-apposing metal stent (LAMS) is spreading improving the outcome of this condition. However, this procedure, although mini-invasive, is burdened with not negligible complications, including misdeployment.

Main body

We report the case of a 60-year-old male with gastric outlet obstruction who underwent ultrasound-guided gastroenterostomy using LAMS. The procedure was complicated by LAMS misdeployment being managed by laparoscopy-assisted placement of a second LAMS.

We performed a systematic review in order to identify all reported cases of misdeployment in EUS-GE and their management. The literature shows that misdeployment occurs in up to 10% of all EUS-GE procedures with a wide spectrum of possible strategies of treatment.

Conclusion

The here reported hybrid technique may offer an innovative strategy to manage LAMS misdeployment when this occurs. Moreover, a hybrid approach may be valuable to overcome this complication, especially in early phases of training of EUS-guided gastroenterostomy.
