1 In the name of Allah In the name of God

2 Esophagus 25 cm muscular tube From pharynx (C6, cricoid cartilage) To stomach (T11) Enters mediastinum between trachea & vertebral column passes through the diaphragm (T10) Function: conducts food from pharynx to stomach

3 Esophagus Relations Anteriorly: - - Trachea - - Recurrent laryngeal nerves - - Left bronchus - - Left atrium - - Left vagus - - Left lobe of liver

4 Esophagus Relations Posteriorly - - Vertebral column - - Azygos - - Thoracic aorta - - Right vagus

5 Esophagus Relations Right side - - Pleura - - Azygos - - Thyroid gland Left side - - Subclavian artery - - Aortic arch - - Pleura - - Thyroid gland

6 Esophageal constrictions At the junction of the esophagus with the pharynx where the esophagus is crossed by the arch of aorta; where the esophagus is compressed by the left main bronchus; at the esophageal hiatus in the diaphragm.

7 Esophagus Arteries: - - Inferior thyroid - - Thoracic Aorta - - Left gastric Veins: - - Inferior thyroid - - Azygos - - Left gastric Nerves: - - Vagus (recurrent laryngeal, ant. & post. gastric, esophageal plexus) - - Sympathetic branches

9 Stomach (gaster, ventriculus) Widest part of GI tract Widest part of GI tract Capacity: 30, 1000 & 1500 ml Capacity: 30, 1000 & 1500 ml Situation: Situation: - Epigastrium - Lt. hypochondriac - Umbilical Stomach bed Stomach bed Functions: Functions: - Storage and - Digestion of food

10 Stomach Has: - - Two borders (curvatures) - - Two surfaces - - Two orifices

11 Lesser curvature Between cardiac and pyloric orifices Descends from right side of esophagus Curving to the right at the angular notch Ends at the pylorus just right to the midline Lesser omentum is attachmented which contains Rt. and Lt. gastric arts.

12 Greater curvature Longer than lesser From cardiac notch Up & postrolateral to the left Highest level at 5 th intercostal space To 10 th costal cartilage Turn right to the pylorus Bulge opposite of angular notch

13 Greater curvature Gastrosplenic lig. & greater omentum are atthached here

14 Surface Anterior (Antrosuperior) - - related to the; Lt. costal margin 6-9 th intercostal space Diaphrgam Ant. Abdominal wall pericardium Lt. pleura & lung Lt and quadrate lobes of liver

15 Surface Posterior (Postro-inferior) Related to the Lesser sac Diaphrgam Lt. suprarenal G. Lt kidney spleen splenic art. Pancreas Lt. colic flexure T. mesocolon

16 Cardiac orifice Behind of the 7 th rib At the level of T11 Lt. to the midline Physiological sphincter 40 cm from incisor teeth Cardiac notch

17 Pyloric orifice Pyloric constrictor (sphincter) cm right to the midline At the level of TPP

18 stomach Has: - - Body - - Fundus - - Pylorus Pyloric Antrum Pyloric canal; 2-3cm

19 Interior of the stomach

20 Blood supply Arteries - - Left gastric - - Right gastric - - Left gastroepiploic - - Right gastroepiploic - - Short gastric veins - - Left gastric - - Right gastric - - Left gastroepiploic - - Right gastroepiploic - - Short gastric

22 Duodenum cm Retroperitoneal Above umbilicus Curves around L2 From pylorus Turns abruptly forward to form duodenojejunal flexure cm below TPP

23 Duodenum Divided into: - - Superior (first), - - Descending, (second) - - Horizontal (third) & - - Ascending (forth) parts

24 Duodenum First part 5 cm, mobile From pylorus to superior flexure First 2.5 cm intraperitoneal duodenal ulcers Second part 8-10 cm From superior flexure to the lower border of L3 Right to the vertebral column hepatopancreatic ampulla Major and minor duodenal papilla

25 Duodenum Third part 10 cm From inferior flexure L3 lower border to the Lt. side Fourth part From … to the level of L2 upper border Left to the Aorta

26 Duodenum Relations - - Pancreas - - Liver - - Gall bladder - - Epiploic foramen - - gasteroduodenal art. - - Rt. Colic flexure - - T. mesocolon - - Jejunum - - Sup. Mesenteric vv

27 Duodenum - - bill duct - - portal vein Rt. Kidney Renal vv IVC Rt. ureter Rt. psoas Rt. & Lt. Gonadal vv Aorta at the level of inf. mesenteric origin

28 Duodenum Duodenal cap Suspensory lig (Treitz) - - Skeletal and smooth muscles

29 Blood supply Arteries - - Superior and Inferior pancreaticoduodenal veins - - Superior and Inferior pancreaticoduodenal

31 Pancreas Grayish – pink cm Situation - - Epigastric - - Lt hypochondriac - - Umbilical

32 Pancreas Consists: - - Head, Uncinate process - - Neck, Constricted part - - Body & Triangular - - Tail In the splenorenal

33 Pancreas Relations: Anterior; - - Duodenum, - - Sup. Mesentric VV., - - Sup. & inf. Pancreaticoduodenal AA - - Transeverse colon, - - Transeverse mesocolon - - Jejunum - - Stomach - - Lt. colic flexure …………… Celiac trunk - - Splenic art. - -

34 Pancreas Relations: Posterior; - - Bile duct, - - Prtal vein - - Splenic vein - - IVC, - - Aorta, - - Sup. Mesentric VV., - - Left suprarenal gland - - Left kidney - - Renal vein,

35 Pancreas Tail - - In (splenorenal) lienorenal lig. Main pancreatic duct Accessory duct ascending in front of main
