Abstract

In this chapter, we will address two topics that will be useful for any endoscopist performing small bowel enteroscopy. First we will review some basic principles to keep in mind when scoping patients with altered small bowel anatomy. We will review the expected anatomy for the most common small bowel surgeries and discuss some tips that might be useful for navigating through the small bowel of these patients. The second half of the chapter will focus on the indications, technique, and adverse events of percutaneous endoscopic jejunostomy placement.
