In this section, common operations performed on the small and large intestine are described. First, operations for small bowel obstruction and superior mesenteric artery embolism are described. Small bowel resection and anastomosis are detailed in Chapter 90 in which the technique of double-layered, hand-sewn anastomosis is introduced; strictureplasty for Crohn disease is also described. Subsequent chapters deal with pediatric problems involving the small bowel, as well as with loop ileostomy and laparoscopic procedures. The general topography of the small intestine and the differences between the jejunum and the ileum have already been illustrated in previous chapters.

The appendix, a diverticulum of the gastrointestinal tract of uncertain significance, is described in Chapters 94 and 95 in which the common operations of traditional and laparoscopic appendectomy are presented. Because the operation for appendicitis sometimes discloses an unexpected Meckel diverticulum, the procedures for resection of this diverticulum are included in these chapters.
