Endoscopic treatment modalities and outcomes in nonvariceal upper gastrointestinal bleeding

Comparison of mechanical and thermal therapy in upper gastrointestinal bleeding: an analysis of efficacy outcomes

Background

Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a complication of dual antiplatelet therapy (DAPT) and direct oral anticoagulant therapy (DOAC). There is a lack of data comparing mechanical therapy (clips) with thermal therapy in this population.

Methods

We conducted a retrospective chart review of patients undergoing urgent/emergent endoscopy for NVUGIB while being on DAPT or DOAC. Patients who had DAPT/DOAC held as per American Society of Gastrointestinal Endoscopy guidelines were excluded from the study.

Results

A total of 122 patients were included in the study. There was no difference in primary hemostasis, rebleeding rate, rescue hemostatic procedure, and 30-day mortality between the mechanical and thermal therapy groups. The mechanical therapy group had a significantly higher rate of prolonged length of stay (61.2% vs 38.9%, P = 0.02), serious clinical outcomes (56% vs 37.5%, P = 0.04), and intensive care unit admissions (50% vs 20.8%, P = 0.001) than the thermal therapy group.

Conclusion

Patients on DAPT/DOAC presenting with NVUGIB can undergo mechanical or thermal endoscopic intervention without a significant difference in achieving primary hemostasis, rebleeding, requiring a secondary procedure, or mortality outcomes.

Development and Validation of Nomograms to Predict Operative Link for Gastritis Assessment Any-Stage and Stages III-IV in the Chinese High-Risk Gastric Cancer Population

Purpose: It is very essential to diagnose gastric atrophy in the area with high prevalence of gastric cancer. Operative link for gastritis assessment (OLGA) was developed to detect the severity of gastric atrophy. The aim of this study was to develop and validate nomograms for predicting OLGA any-stage and stages III-IV in the Chinese high-risk gastric cancer population. Methods: We retrospectively analyzed 7,945 participants obtained by a multicenter cross-sectional study. We randomly selected 55% individuals (4,370 participants, training cohort) to analyze and generate the prediction models and validated the models on the remaining individuals (3,575 participants, validation cohort). A multivariate logistic regression model was used to select variables in the training cohort. The corresponding nomograms were developed to predict OLGA any-stage and stages III-IV, respectively. The area under the receiver operating characteristic curves and the GiViTI calibration belts were used to estimate the discrimination and calibration of the prediction models. Results: There were 1,226 (28.05%) participants in the training sample and 970 (27.13%) in the validation sample who were diagnosed with gastric atrophy. The nomogram predicting OLGA any-stage had an area under the curve (AUC) of 0.610 for the training sample and 0.615 for the validation sample, with favorable calibrations in the overall population. Similarly, the nomogram predicting OLGA stages III-IV had an AUC of 0.702 and 0.714 for the training and validation samples, respectively, with favorable calibrations in the overall population. Conclusions: The prediction model can early identify the occurrence of gastric atrophy and the severity stage of gastric atrophy to some extent.

Study on the preventive effect of intravenous esomeprazole in the management of nonvarices upper gastrointestinal bleeding

This retrospective study investigated the preventive effect of intravenous esomeprazole (IVEO) in the prevention of nonvarices upper gastrointestinal bleeding (NUGIB).This study enrolled 130 patients with NUGIB and all of them underwent successful endoscopic hemostasis, of which 65 cases received routine management and IVEO (Group A) and the other 65 cases received routine management alone (Group B). The primary outcome (recurrent bleeding rate within 72-hour, 7-day, and 30-day), and secondary outcomes ((all-cause mortality, bleeding-related mortality, blood transfused, hospital stay (day), and incidence of adverse events)) were compared between 2 groups.Patients in the group A showed lower recurrent bleeding rate within 72-hour(P < .05), 7-day (P < .05), and 30-day (P < .05), than that of patients in the group B. However, no significant differences were identified in all-cause mortality(P = .26), bleeding-related mortality (P = .57), blood transfused (P = .33), and hospital stay (P = .74) between 2 groups. In addition, both groups had similar safety profile.This study found that routine management and IVEO was superior to the routine management alone for preventing the recurrent bleeding rate after successful endoscopic hemostasis in patients with NUGIB.

Endoscopic obturation with tissue adhesive for bleeding gastric stromal tumor: a case report

Primary endoscopic hemostasis for bleeding gastrointestinal stromal tumor (GIST) is rarely reported. Herein, we report the case of a patient with a bleeding GIST that was treated with endoscopic obturation with tissue adhesive. A 46-year-old man presented with hematemesis and tarry stool for 1 day. Upper GI endoscopy revealed a bleeding submucosal tumor at the stomach fundus and an exposed pulsatile vessel was seen at the defect. Endoscopic obturation with tissue adhesive was performed to treat the defect and the bleeding was successfully stopped. No recurrence of bleeding was observed through a gastric tube, and 6 days after endoscopic obturation, the patient underwent laparoscopic partial gastrectomy. Endoscopic obturation with tissue adhesive is a feasible and effective method to treat bleeding GIST.
