Endoscopic Studies I: Bronchoscopy and Thoracoscopy

179
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Endoscopic Procedures V: ERCP

136
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Area of Science:

  • Hepatobiliary surgery
  • Gastroenterology
  • Oncology

Background:

  • Liver cancer resection near the hepatic hilum presents surgical challenges.
  • Balancing remnant liver volume and bile duct safety is critical.

Purpose of the Study:

  • To evaluate preoperative endoscopic nasobiliary drainage (ENBD) tube placement.
  • To assess its efficacy as an intraoperative guide for bile duct preservation during liver resection.

Main Methods:

  • Retrospective review of 16 patients with liver cancer near the hepatic hilum.
  • Preoperative ENBD tube placement followed by curative liver resection.
  • Assessment of risks, short-term outcomes, and local recurrence.

Main Results:

  • ENBD tube placement was successful in all patients, with no procedure-related pancreatitis.
  • Surgeons utilized the ENBD tube for precise bile duct preservation in all cases.
  • Low rates of bile leakage (6.3%), no liver failure, and acceptable local recurrence (6.3%) were observed.

Conclusions:

  • Preoperative ENBD tube placement is a safe endoscopic-surgical approach.
  • It facilitates optimal liver preservation and local control for challenging liver resections.
  • This technique offers a collaborative solution for complex hepatobiliary procedures.
