Endoscopic Procedures I: Esophagogastroduodenoscopy

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Summary

This summary is machine-generated.

Post-endoscopic submucosal dissection (ESD) coagulation syndrome (PECS) can be predicted using a new scoring system. This tool helps differentiate PECS from delayed perforation (DP) after ESD procedures.

Area of Science:

Gastroenterology
Endoscopic Procedures
Surgical Complications

Background:

Post-endoscopic submucosal dissection (ESD) coagulation syndrome (PECS) presents with abdominal pain and inflammation, mimicking delayed perforation (DP).
Accurate differentiation between PECS and DP is crucial for appropriate patient management following ESD.

Purpose of the Study:

To evaluate clinical and biochemical characteristics differentiating PECS from DP after colorectal ESD.
To develop and validate a predictive scoring system for early identification of PECS.

Main Methods:

Retrospective analysis of 318 patients undergoing colorectal ESD.
Classification into PECS (n=32), DP (n=7), and no-PECS/no-DP (NPD) (n=279) groups.
Multivariate analysis to identify PECS predictors, leading to the development of a five-variable PECS-predictive scoring system (FPSS).

Main Results:

The incidence of PECS and DP was 10.1% and 2.2%, respectively.
DP showed greater CRP elevation and leukocytosis than PECS.
Key predictors for PECS included right colon location, female gender, elevated body temperature, higher day 1 WBC count, and larger lesion size.
The FPSS demonstrated an AUC of 0.881 with a high negative predictive value (97.4%).

Conclusions:

The study clarified the distinct characteristics of PECS compared to NPD and DP.
The newly developed FPSS offers excellent diagnostic performance for predicting PECS after colorectal ESD.
