Abdominal Aorta01:25

Abdominal Aorta

2.4K
Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Cavity Drainage and Flashings in Masonry walls

475
Typically, a cavity wall consists of two wythes separated by a gap of at least 2 inches, which may contain insulation while still maintaining a minimum clear space of 1 inch to facilitate adequate drainage. Advanced methods like the insertion of a continuous drainage mat can further reduce this space while ensuring effective moisture expulsion.
Weep holes, strategically placed at the base of the cavity, are critical for draining accumulated water. These openings are created by leaving head...

Ultrasound I: Abdominal Ultrasonography

1.7K
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Abdominal Regions and Quadrants01:19

Abdominal Regions and Quadrants

17.8K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

Pancreatic Juice and Secretion01:26

Pancreatic Juice and Secretion

3.1K
Pancreatic juice is a clear fluid produced by the pancreas, containing water, salts, sodium bicarbonate, and enzymes vital for digestion in the small intestine. It helps break down large molecules, facilitating nutrient absorption.
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...

Acute Pancreatitis I: Introduction01:27

Acute Pancreatitis I: Introduction

1.3K
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:

Summary

Routine abdominal drainage after pancreatic surgery shows no clear benefit for 30-day mortality or complications. However, it may slightly reduce 90-day mortality, with active drains and early removal potentially shortening hospital stays.

Area of Science:

  • Surgical Oncology
  • Gastrointestinal Surgery
  • Evidence-Based Medicine

Background:

  • The necessity of surgical drains after pancreatic surgery is debated.
  • Prophylactic abdominal drainage's role in mitigating postoperative complications remains controversial.

Purpose of the Study:

  • To evaluate the benefits and risks of routine abdominal drainage post-pancreatic surgery.
  • To compare the efficacy of different surgical drain types.
  • To determine the optimal timing for drain removal.

Main Methods:

  • Systematic review and meta-analysis of randomized controlled trials (RCTs).
  • Included studies compared abdominal drainage versus no drainage, different drain types, or varying drain removal schedules.
  • Data extracted and analyzed using Review Manager 5 with random-effects models.

Main Results:

  • Drain use showed little difference in 30-day mortality but probably reduced 90-day mortality.
  • Uncertainty exists regarding drain use's impact on intra-abdominal infections and radiological interventions.
  • Active drains and early drain removal may offer slight reductions in hospital stay duration.

Conclusions:

  • The effect of routine abdominal drainage on 30-day mortality and complications is unclear.
  • Moderate evidence suggests a probable slight reduction in 90-day mortality with drain use.
  • Low-quality evidence indicates potential benefits of active drains and early removal for hospital stay.
