Abstract

Objective:

Aim: To investigate the risk factors for PEP in patients with choledocholithiasis.

Patients And Methods:

Materials and Methods: We have retrospectively analyzed 253 cases with choledocholithiasis that underwent ERCP. The primary endpoint was the occurrence of PEP. A number of potential risk factors for PEP were taken into account: gender, age ( 10 mm); type of choledocholithiasis - microcholedocholithiasis, choledocholithiasis (1-2 stones), multiple choledocholithiasis (≥ 3 stones) and choledocholithiasis due to Mirizzi syndrome; periampullary diverticulum; papilla size (≤5 or >6 mm); ERCP success; selective biliary cannulation; pancreatic cannulation/injection; precut; papillotomy.

Results:

Results: PEP was in 8 (3,2 %) cases. Univariate analysis identified two factors associated with PEP - common bile duct ≤10 mm (P=0.045) and papilla ≤5 mm (P=0.036). In multivariate analysis, among all variables only the common bile size ≤10 mm appeared to be significant (P=0.018).

Conclusion:

Conclusions: In patients with choledocholithiasis the occurrence of PEP is related to common bile duct size less than 10 mm.

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...

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

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...

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:
