• 1 other identifier: RP027
• Study Type: observational
• Target: 75
• Locations: 1 country
• Sites: 2

Brief Summary

The goal of this observational study is to learn about the carbon footprint produced from diagnostic upper GI endoscopy in patients with dyspepsia and therapeutic upper GI endoscopy in patients with non-variceal upper GI bleeding. The main question it aims to answer is: • How much carbon footprint is generated from upper GI endoscopy Participants are already receiving diagnostic and therapeutic upper GI endoscopy as part of their regular medical care for dyspepsia and non-variceal upper GI bleeding, respectively. The carbon footprint generated from this treatment process is examined.

Conditions

Carbon Footprint in Upper GI Endoscopy; Dyspepsia; Non-variceal Upper Gastrointestinal Bleeding

Keywords

Carbon footprint; Upper GI endoscopy; EGD; Dyspepsia; Non-variceal upper gastrointestinal bleeding

Outcome Measures

Primary Outcomes (1)

• To quantify the carbon footprint of diagnostic endoscopy for dyspepsia and therapeutic endoscopy for peptic ulcer bleeding

  The primary outcome is to calculate the carbon footprint produced from diagnostic upper GI endoscopy in dyspepsia patients and therapeutic upper GI endoscopy in peptic ulcer patients, focusing on the carbon footprint produced since the patient enter the endoscopy room until they leave the endoscopy room

  From enrollment to the time that patients leave the endoscopy room

Secondary Outcomes (3)

• To compare carbon emissions between diagnostic and therapeutic upper GI endoscopy

  From enrollment to the time that patients leave the endoscopy room

• To compare emissions across different hemostatic techniques (clips, argon plasma coagulation, bipolar probe), with or without epinephrine.

  From enrollment to the time that patients leave the endoscopy room

• To evaluate procedural success rates of bleeding stoppage and adverse events (e.g., perforation, post-procedural sepsis) by different techniques

  From enrollment to 30 days after treatment
