++
++
++

++
++

B. Includes predominant supply of the greater curve of the stomach by the left gastric artery

++
++

C. Includes the right gastroepiploic artery, which is usually a branch of the splenic artery

++
++

D. May include a posterior gastric artery that is typically a branch of the splenic artery

++
++

E. Is anatomically separate from the blood supply to the spleen

+
++

D. May include a posterior gastric artery that is typically a branch of the splenic artery

++

The four functions of the stomach include all of these except

++
++
++

++
++

B. It is the site of the initial stage of protein and ­carbohydrate digestion.

+
++

D. It is the site of the assembly of micelles for nutrient absorption

++
++
++

Reconstruction of gastrointestinal continuity after resection of portions of the stomach

++
++
++

A. Usually includes a roux-en-Y reconstruction after distal gastrectomy

++
++

B. Cannot be done by Billroth I reconstruction after total gastrectomy

++
++

C. Includes a gastroduodenostomy for Billroth II reconstruction

++
++

D. Has a risk of duodenal stump leak after Billroth I reconstruction

++
++

E. May require conversion to a Billroth II reconstruction if a patient develops bile gastritis after a Billroth I approach

+
++

B. Cannot be done by Billroth I reconstruction after total gastrectomy

++
++
++

Vagotomy

++
++
++

A. Can impair the appropriate relaxation of the pylorus

++
++

B. Has several variations, but each denervates the pylorus

++
++

C. Has become more widely applied as ulcer therapy since the introduction of acid-suppressing medications (H2-blockers and proton pump inhibitors)
