Abstract

Objective:

To evaluate the efficacy and safety of early pancreatic stenting in patients with acute biliary pancreatitis.

Material And Methods:

We retrospectively analyzed the effect of early (within 48 hours after admission) pancreatic stenting on severity of disease, incidence of complications, mortality and hospital-stay in patients with severe acute biliary pancreatitis. Moreover, there were patients with acute biliary pancreatitis who underwent delayed endoscopic retrograde intervention and only conservative therapy.

Results:

Early pancreatic stenting reduced the risk of local (p=0.047) and systemic complications (p=0.027) compared to delayed intervention and conservative treatment. Early pancreatic stenting contributed to shorter hospital-stay when compared with delayed intervention (p=0.038). There was no between-group difference in mortality or severity of disease. Pancreatic stenting after 48 hours had no advantages over early stenting or conservative treatment, but significantly increased the risk of infected pancreatic necrosis (p=0.023).

Conclusion:

Early pancreatic stenting seems to be safe and effective procedure in reducing the number of complications in patients with acute biliary pancreatitis. Neither early nor late pancreatic stenting has a significant effect on disease severity, mortality and hospital-stay.

Acute Pancreatitis II: Clinical Manifestations and Management

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Chronic Pancreatitis II: Collaborative Care

The management of chronic pancreatitis is multifaceted, involving a comprehensive approach that includes thorough assessment, diagnostic testing, and a variety of management strategies.

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Chronic Pancreatitis I: Introduction

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
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...

Acute Pancreatitis I: Introduction

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
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:
