Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

363
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...

Endoscopic Procedures V: ERCP

44
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.

Depolarizing Blockers: Pharmocokinetics

297
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

56
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...

Diseases of the Liver and Gallbladder01:26

Diseases of the Liver and Gallbladder

393
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Summary
This summary is machine-generated.

Biliary dyskinesia, a gallbladder motility disorder, often affects women and presents with abdominal pain. Cholecystectomy effectively resolves symptoms in these patients, even with normal ultrasound findings.

Area of Science:

  • Gastroenterology
  • Surgical Pathology

Background:

  • Biliary dyskinesia is a functional gallbladder disorder characterized by abnormal motility.
  • It presents with biliary symptoms but lacks structural pathology on standard imaging.
  • Diagnosis relies on abnormal gallbladder ejection fraction via HIDA-CCK scans.

Purpose of the Study:

  • To investigate the pathological findings in patients with biliary dyskinesia undergoing cholecystectomy.
  • To assess symptom resolution following gallbladder removal in this patient group.

Main Methods:

  • Retrospective cohort study of patients with symptomatic cholelithiasis or biliary dyskinesia from 2015-2019.
  • Assessment of clinical symptoms, imaging, and surgical pathology.
  • Primary endpoints: pathologic changes and symptom resolution; Secondary endpoints: correlation with demographics.

Main Results:

  • Of 415 patients, 89 (21%) had biliary dyskinesia, predominantly women (92%) with a mean age of 46 and BMI of 28.
  • Abdominal pain was the most common symptom (97%).
  • Pathology revealed chronic cholecystitis in 84% of biliary dyskinesia patients; all patients experienced symptom resolution post-cholecystectomy.

Conclusions:

  • Biliary dyskinesia patients are typically younger, female, and have lower BMIs compared to those with cholelithiasis.
  • Histological evidence of chronic gallbladder inflammation is common.
  • Cholecystectomy is an effective treatment for biliary dyskinesia, resolving symptoms and should be considered first-line therapy.
