Background:
Patients should be informed beforehand of the risk factors for exocrine pancreatic insufficiency (ExoPI) after pancreatic surgery; however, there are no clear identified risk factors for this condition. This study aimed to identify the preoperative, perioperative and postoperative risk factors for ExoPI after pancreatic surgery.
Methods:
We conducted a systematic search of PubMed, Scopus, SAGE, CINAHL Plus and Taylor & Francis from inception to Mar. 7, 2021, for full-text articles that included patients who had undergone pancreatic surgery. The primary outcome was the number of ExoPI events and any risk factors evaluated. We used the Newcastle-Ottawa Scale to assess study quality.
Results:
Twenty studies involving 4131 patients (2312 [52.3%] male, mean age 60.12 [standard deviation 14.07] yr) were included. Of the 4131 patients, 1651 (40.0%) had postoperative ExoPI. Among the 11 factors evaluated, the significant risk factors were preoperative main pancreatic duct (MPD) diameter greater than 3 mm (odds ratio [OR] 4.50, 95% confidence interval [CI] 1.06-19.05), pancreaticoduodenectomy (PD) as the surgical treatment procedure (OR 3.31, 95% CI 1.92-5.68), pancreaticogastrostomy (PG) as the anastomotic procedure (OR 3.13, 95% CI 1.83-5.35), hard pancreatic texture (OR 2.93, 95% CI 1.99-4.32) and adjuvant chemotherapy (OR 2.50, 95% CI 1.54-4.04). Gender, history of diabetes mellitus or endocrine pancreatic insufficiency (EndoPI), underlying diseases, de novo diabetes or EndoPI, pylorus-preserving PD and postoperative pancreatic fistula were not risk factors for ExoPI after pancreatic surgery.
Conclusion:
Preoperative MPD diameter greater than 3 mm, PD, PG reconstruction, hard pancreatic texture and adjuvant chemotherapy were risk factors for the development of ExoPI after pancreatic surgery. The findings should provide useful information for patients to reduce postoperative dissatisfaction and improve quality of life.

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...

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
