Intraoperative endoscopy (IOE) is a vital tool for identifying hidden or synchronous lesions during laparoscopic colonic surgery when preoperative imaging is insufficient. This safe and effective technique aids in precise lesion localization and can alter surgical plans when necessary.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Preoperative endoscopic evaluation may be inadequate for complex colorectal conditions.
  • Intraoperative endoscopy (IOE) serves as a crucial adjunct when preoperative studies are insufficient.
  • IOE is essential for identifying synchronous, nonpalpable, or bleeding lesions during laparoscopic colonic surgery.

Purpose of the Study:

  • To report the experience and techniques of transabdominal intraoperative endoscopy (IOE).
  • To evaluate the utility and safety of IOE in laparoscopic colonic surgery.
  • To assess the impact of IOE on surgical procedure extent and patient outcomes.

Main Methods:

  • A retrospective review of IOE procedures performed at University of Miami-affiliated hospitals.

  • Analysis of 58 patients undergoing IOE between July 1994 and August 1996.
  • Inclusion of colonoscopies (transanal and transabdominal) and flexible sigmoidoscopies.

    • Main Results:

    • IOE was performed on 58 patients, with 47 colonoscopies and 11 flexible sigmoidoscopies.
    • Common indications included colorectal cancer, diverticulitis, inflammatory bowel disease, and lower GI bleeding (83% of cases).
    • IOE altered the surgical procedure extent in 10% of cases, with no reported complications.

    Conclusions:

    • Intraoperative endoscopy (IOE) is an essential, safe, and effective tool for selected patients undergoing colorectal procedures.
    • IOE facilitates accurate lesion identification and localization, especially when preoperative assessments are limited.
    • The technique can be rapidly performed, improving surgical decision-making during laparoscopic colonic surgery.
