Exploration of lymphatic structures of gastrointestinal tract
Inferior mesenteric lymph nodes and vessels, general view
The small intestine and its mesentery have been retracted to the right. The transverse colon has been elevated. The peritoneum has been removed from a large area to the left of the root of the mesentery and also from the area close to the splenic flexure of the colon. Lymphatic structures located along the course of branches of the inferior mesenteric artery have been preserved wherever possible.
- Middle colic artery
- Transverse colon (elevated)
- Liver
- Jejunum (retracted to the right)
- Mesenteries
- Ileum (retracted to the right)
- Pelvic cavity
- Left colic flexure
- Left colic lymph nodes
- Ascending branch of inferior mesenteric artery
- Duodenojejunal flexure
- Peritoneum (intact strip between dissected areas)
- Ascending part of duodenum
- Descending colon
- Psoas major muscle (covered by fascia)
- Fascia covering inferior mesenteric artery
- Sigmoid artery
- Inferior mesenteric lymph nodes
- Sigmoid colon
