Summary
Chyle leak remains a significant complication after pancreatic surgery, with an overall incidence of 8.0%. Robotic and open pancreatoduodenectomy show no significant difference in chyle leak rates.
Area of Science:
- Gastroenterology and Hepatology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Chyle leak is a serious complication following pancreatic resection, impacting patient morbidity and mortality.
- Existing data on chyle leak incidence, risk factors, and treatment are inconsistent.
- Robotic pancreatic surgery is perceived to reduce complications compared to open procedures.
Purpose of the Study:
- To evaluate the incidence and risk factors of chyle leak after pancreatic resection.
- To compare chyle leak rates between open and robotic pancreatic surgery.
- To review therapeutic strategies for managing chyle leak.
Main Methods:
- A comprehensive scoping literature review was performed.
- Searched multiple databases for studies on open or robotic pancreatic resection with chyle leak.
- Included studies defined chyle leak per the International Study Group on Pancreatic Surgery criteria.
Main Results:
- Analyzed 58 studies (30,039 patients) from 2007-2025.
- Pooled incidence of chyle leak after pancreatic resection was 8.0%.
- Incidence varied by procedure: 9.5% (partial pancreatoduodenectomy) to 1.7% (enucleation).
- Comparative studies showed 10% chyle leak for robotic vs. 12% for open pancreatoduodenectomy.
Conclusions:
- Chyle leak is a substantial risk following pancreatic resection.
- Surgical technique advancements have not eliminated this complication.
- No significant difference in chyle leak rates between robotic and open pancreatoduodenectomy was observed.

Physics is concerned with the interactions of energy, matter, space, and time, in order to discover the underlying mechanisms that underpin all phenomena. The word "physics" comes from the Greek word "phúsis", which means nature. Physics seeks to comprehend the natural world around us at its most fundamental level. It emphasizes the use of quantitative laws to do this, which could be valuable in other fields that want to push the performance boundaries of present...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

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...

01:27Acute 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:
