Summary
Endoscopic ultrasonography (EUS), both conventional and interventional, is a safe procedure with a low complication rate. This study found a 0.12% overall complication rate across 11,539 EUS procedures.
Area of Science:
- Gastroenterology
- Medical Imaging
- Interventional Endoscopy
Background:
- Endoscopic ultrasonography (EUS) use has increased over 20 years.
- EUS is considered safe, but complication rates require further study.
- This multicenter study aimed to determine the complication rate of EUS procedures.
Purpose of the Study:
- To establish the complication rate for conventional and interventional endoscopic ultrasonography.
- To analyze factors influencing complication rates in EUS procedures.
Main Methods:
- Data collected via questionnaire from six centers on 11,539 EUS procedures (10,731 conventional, 808 interventional).
- Information gathered on procedural details, sedation, instruments, and lesion characteristics for interventional EUS.
- Complications classified by severity (mild, moderate, severe, fatal) and onset (immediate, early, late).
Main Results:
- No deaths reported in 11,539 EUS procedures.
- Overall complication rate was 0.12% (14/11,539).
- Interventional EUS had a higher complication rate (1.11%) compared to conventional EUS (0.046%).
Conclusions:
- Both conventional and interventional endoscopic ultrasonography are acceptably safe techniques.
- The study confirms the low complication profile of EUS, even with interventional procedures.

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.

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...
