What is located in the hepatoduodenal ligament?
The portal triad consisting on the proper hepatic artery, common bile duct, and portal vein. When performing a cholecystectomy and lose the cystic artery, want to compress this ligament to stop it from bleeding profusely.
What is the duodenal papillae?
Where the sphincter of Oddi opens into the duodenum
What is the duodojejunal junction?
Where the ligament of Treitz is located. When the ligament contracts, it will increase the lumen of the intestine to make it easier for food to pass through
What covers the posterior surface of the rectus abdomens muscle above the arcuate line?
The rectus sheath
What covers the posterior surface of the rectus abdomens muscle below the arcuate line?
Transversalis fascia
What is contained in the gastrosplenic ligament?
The ligament runs from the stomach to the hilum of the spleen and contains the short gastric and left gastro-omental arteries
Where do the SMA and IMA anastomose in the colon?
Via the marginal artery of Drummond in the transverse colon
What is a sliding hiatal hernia?
Protrusion of the stomach into the thorax through the esophageal hiatus which only contains the cardia of the stomach
What is a paraesophageal hiatal hernia?
Pouch of peritoneum that protrudes usually includes part of the fundus
What is contained in the splenorenal ligament?
The tail of the pancreas and splenic vessels
Summarize the dual blood supply of the liver.
70% comes from the portal vein and 30% comes from the hepatic artery.
Where should the needle be inserted for a liver biopsy?
The 10th ICS
Where will pain be located in cholecystitis?
In the epigastric region to the right hypochondriac region of the abdomen
Where does fluid drain in peritonitis if the infection originates due to a perforated ulcer on the posterior part of the stomach?
Omental bursa -> subphrenic recess -> pericolic gutter
Want to sit them up so that it remains in the pelvic region which is not as heavily vascularized to prevent the infection from spreading
What is the ligamentum trees a remnant of?
The umbilical vein
What is the ligamentum venous a remnant of?
Ductus venosus
What is the reason you have haustra?
Because the teniae coli is shorter than the length of the colon - so want to pull up on the colon
Where is the primary place you get volvulus?
The cecum
What is the subphrenic recess?
Located between the liver and the diaphragm
What branch of the facial nerve innervates the sublingual and submandibular salivary glands?
Chorda tympani
What is the iliohypogastric nerve?
Provides sensory innervation to skin of the lower abdomen; a branch of the lumbar plexus that can be injured in appendectomy
What provides blood flow to the rectus abdominus muscle if the internal thoracic artery is cut for heart bypass?
The inferior epigastric artery; if the internal thoracic was ligated, blood would no longer flow to superior epigastric which normally supplies the rectus abdominus
However, the superior and inferior epigastric anastomose and thus blood can flow in a collateral direction as follows: external iliac -> inferior epigastric -> superior epigastric -> rectus abdominus
Where does the gastroduodenal artery descend?
Behind the first part of the duodenum - thus it can be injured if a duodenal ulcer eats through the duodenum
Why is occlusion of the IMA seldom symptomatic?
Because the middle colic artery also supplies the transverse colon and can supply collateral flow to the area of the IMA through the marginal artery of Drummond
