[Laparoscopy in differential internal medicine diagnosis]

Area of Science:

• Minimally invasive surgical techniques
• Diagnostic imaging and endoscopy
• Gastroenterology and surgical oncology

Context:

• Despite advances in non-invasive imaging, diagnostic laparoscopy retains significant value in differential diagnosis.
• Key indications include staging malignancies (esophageal, stomach, pancreatic) and evaluating chronic liver diseases.
• It is particularly effective in diagnosing peritoneal metastases, preventing unnecessary exploratory laparotomies.

Purpose:

• To highlight the continued importance of diagnostic laparoscopy in modern medicine.
• To compare different laparoscopic approaches (mini-laparoscopy, conventional laparoscopy) for tumor staging.
• To emphasize its role in diagnosing liver diseases and unexplained conditions.

Summary:

• Laparoscopy significantly enhances the predictability of resectability for distal esophageal, stomach, and pancreatic cancers.
• It is the gold standard for diagnosing peritoneal metastases, thereby avoiding exploratory laparotomies.
• Minilaparoscopy shows increasing promise for diagnosing chronic liver diseases, including liver cirrhosis and hepatocellular carcinoma.
• Laparoscopic ultrasonography is highly sensitive for detecting small liver tumors, such as metastases and hepatocellular carcinoma.

Impact:

• Improves surgical planning and patient outcomes by accurately staging cancers.
• Reduces healthcare costs and patient morbidity by preventing non-therapeutic laparotomies.
• Enhances diagnostic accuracy for complex conditions like liver cirrhosis and fever of unknown origin.
