Intussusception is defined as telescoping of the proximal bowel (intussusceptum) into the lumen of the distal bowel, otherwise called the intussuscipiens. While it is one of the most common causes of intestinal obstruction in children between the ages of 3 months and 6 years, intussusception accounts for about 1% of such cases in adults. Intussusception is idiopathic in 8-20% of patients and most commonly occurs in the small intestines in adults.

- Endoscopic submucosal dissection (ESD) is a technique used to remove early-stage gastrointestinal tumors, primarily in Asia, but its adoption in Western countries is limited, prompting this study on its learning curve in the U.S.
- A retrospective analysis of 540 ESD cases performed by a single operator revealed that proficiency benchmarks for successful resections were reached after approximately 250 procedures, with en bloc resection rates increasing significantly before plateauing.
- The study concludes that training for ESD takes longer in the West due to the complexity of lesions tackled early in training, differing from the experiences in Asia.
