Esophagoduodenoscopy or colonoscopy: which should be done first?

Area of Science:

• Gastroenterology
• Anesthesiology
• Medical Procedures

Background:

• Bidirectional endoscopy combines esophagoduodenoscopy and colonoscopy in one session.
• The optimal sequence for these procedures is not well-established.

Purpose of the Study:

• To compare anesthetic requirements and hemodynamic effects of initiating bidirectional endoscopy with either esophagoduodenoscopy or colonoscopy.

Main Methods:

• Eighty patients (ASA I-III) were randomized into two groups: Group C (colonoscopy first) and Group E (esophagoduodenoscopy first).
• Standard anesthesia with fentanyl and propofol was administered.
• Data collected included vital signs, sedation scores, propofol consumption, procedure duration, retching, time to cecum, recovery time, and satisfaction.

Main Results:

• Group E had significantly longer total procedure and esophagoduodenoscopy durations.
• Complication frequency and additional propofol requirements were higher in Group E.
• Endoscopist and patient satisfaction were lower in Group E, with no significant difference in retching or time to cecum.

Conclusions:

• Initiating bidirectional endoscopy with colonoscopy first is associated with shorter procedural duration, reduced propofol consumption, and fewer complications.
• This sequence appears to be a preferable strategy for bidirectional endoscopic procedures.
