Surgical Management of Intestinal Disorders Quiz

Surgical Management of Intestinal Disorders: Key Points

• The small intestines extend from the pylorus to the ileocecal junction and measure about 4-6 meters in adults.
• The small intestine is divided into different segments: duodenum, jejunum, and ileum.
• The duodenum has four portions, with the first portion being intraperitoneal and the rest retroperitoneal.
• The duodenum is part of the foregut and wraps around the pancreatic head.
• The jejunum is intraperitoneal and is part of the midgut.
• The ileum is part of the midgut and is divided into a distal 3/5 jejunoileal segment and a proximal 2/5 jejunoileal segment.
• The ileum is larger in diameter, has a thicker wall, and has a less fatty mesentery compared to the jejunum.
• The ileum also has more prominent plicae circulares, longer vasa recta, fewer vascular arcades, and fewer Peyer's patches.
• The small intestine has a segmental arterial blood supply and lymph drainage.

• Surgical management of intestinal disorders involves treating disorders such as small bowel obstruction, intestinal fistula, Mackles Diverticulum, mesenteric ischemia, and neoplasms.
• Surgical anatomy and understanding the different segments of the small intestine are important for successful surgical management of intestinal disorders.
