Endoscopic submucosal dissection (ESD) shows better outcomes in Eastern countries compared to Western countries, particularly in curative resection rates. Western countries experienced higher complication rates and longer procedure times for ESD.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endoscopic Procedures
Background:
- Endoscopic submucosal dissection (ESD) is a minimally invasive technique for gastrointestinal lesion resection.
- Significant regional variations in ESD outcomes may exist, necessitating comparative analysis.
Purpose of the Study:
- To compare the efficacy and safety of endoscopic submucosal dissection (ESD) between Eastern and Western countries.
- To identify factors contributing to outcome disparities in ESD procedures.
Main Methods:
- A systematic review and meta-analysis of studies published between 1990 and February 2016.
- Inclusion of data from PubMed, MEDLINE, Web of Science, CINAHL, and EBM reviews.
- Primary outcome: curative, en bloc, and R0 resection rates; Secondary outcomes: complications, recurrence, and procedure time.
Main Results:
- Analysis of 238 publications involving 84,318 patients and 89,512 resected lesions.
- Eastern countries demonstrated significantly higher pooled rates for curative (82% vs. 71%), en bloc (95% vs. 85%), and R0 resections (89% vs. 74%) compared to Western countries.
- Western countries had a higher incidence of perforation requiring surgery (0.53% vs. 0.01%) and longer procedure times (110 min vs. 77 min).
Conclusions:
- Eastern countries exhibit superior outcomes in endoscopic submucosal dissection (ESD) compared to Western countries.
- Regional expertise and localized outcomes are crucial considerations for optimizing ESD treatment decisions.
- Further investigation into the reasons for these disparities is warranted.
