Effects of gastric surgery upon gastric emptying in cases of peptic ulceration.

Postoperative gastrointestinal physiology following operations on the stomach

“…In a classical paper [23] from the fifties, anemia developed gradually over the years with a more rapid appearance of anemia in patients losing blood (such as menstruating women). Anemia can develop as a result of deficiencies in iron, vitamin B 12 and/or folate. Iron deficiency is the most common cause and most postoperative anemias are microcytic and hypochromic.…”

“…The data base is insufficient to document differences in gastric emptying rates between the two operations, but current evidence suggests the following: liquid leave the stomach more rapidly and solid food components [10][11][12].…”

“…The loss of gastric intrinsic factor leads to malabsorption of vitamin B 12 ; as a consequence, the patients develop vitamin B 12 deficiency and require regular substitution [5]. This factor is only of importance after gastric resection (Billroth I, Billroth II, subtotal or total gastrectomy); after surgical procedures such as highly selective or truncal vagatomy, patients should not develop malabsorption of vitamin B 12 .…”

Influence of the Length of Heineke-Mikulicz Pyloroplasty on the Area of Gastric Outlet

“…Functional changes in gastric emptying after surgery have produced conflicting results, but various meals of different composition have been used in these assessments (2,3,5,7). It is possible that the size of the gastric outlet is a factor governing gastric emptying.…”

Effect of Antrectomy on Small Intestinal Structure and Function in the Rat

“…This model, however, in duces complex alterations in gastroenterolog ical ecology such as reduced acid secretion [3], gastric emptying [7,20], changes in the release of other hormones [4. 15], changes in pancreatic and biliary secretion [20] and changes in the utilization of food, and all of them may affect the mucosa.…”
