Introduction:
A central pancreatectomy is a parenchyma-sparing procedure that is performed to reduce long-term endocrine and exocrine insufficiency.
Method:
In this study, we analyzed the perioperative course, the frequency of postoperative onset of diabetes mellitus, and long-term change of body weight in patients undergoing a central pancreatectomy, in comparison to the patients undergoing a distal pancreatectomy for low-grade neoplasms including cystic neoplasms and neuroendocrine tumors.
Results And Discussion:
The rate of postoperative complications including grade B/C pancreatic fistula was no different between both groups. Only one patient undergoing a central pancreatectomy (4.7%) developed new onset of mild diabetes, whereas 35% in the distal pancreatectomy group developed new onset or worsening diabetes (p = 0.0129). The body weight in the distal pancreatectomy group was significant lower than that in the central pancreatectomy group at 1 and 2 years after surgery (1 year; P < 0.0001, 2 years; P = 0.0055), and the body weight in the patients undergoing a central pancreatectomy improved to preoperative values within 2 years after surgery.
Conclusion:
A central pancreatectomy is a safe procedure for the treatment of low-grade malignant neoplasms in the pancreatic body; the rate of onset of diabetes is minimal, and the body weight improves early in the postoperative course.

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...
