Purpose:
To investigate the phenomenon of pancreatic atrophy after gastrectomy for gastric cancer, using computed tomography (CT) volumetry.
Methods:
The subjects of this retrospective study were 77 patients who underwent distal gastrectomy (DG) or total gastrectomy (TG) for pStage I gastric cancer in 2014. The relative pancreatic volume ratio was assessed preoperatively, and then 1 and 5 years postoperatively and the results were compared between surgical procedures RESULTS: A total of 14 patients underwent TG with Roux-en-Y (RY) reconstruction, 24 underwent DG with Billroth-I (BI) reconstruction, and 39 underwent DG with RY reconstruction. We observed that the pancreatic volume continued to decrease over the 5 years after DG or TG. Furthermore, the incidence of pancreatic atrophy 5 years postoperatively was significantly greater after TG than after DG. In patients who underwent DG, a greater incidence of pancreatic atrophy was observed after RY reconstruction than after BI reconstruction, 5 years postoperatively.
Conclusion:
The pancreatic volume continued to decrease after DG and TG for gastric cancer 5 years after treatment. TG was associated with a significantly greater incidence of pancreatic atrophy than DG 5 years postoperatively, as was RY reconstruction vs. BI reconstruction after DG.

01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
