Summary
Laparoscopic intracorporeal ultrasound (LICU) aids in diagnosing liver tumors and defining hepatobiliary anatomy during surgery. This minimally invasive technique accurately identifies common bile duct stones and aids in pancreatic cancer staging.
Area of Science:
- Minimally Invasive Surgery
- Medical Imaging
- Gastroenterology
Background:
- Ultrasonography offers diverse clinical applications via external and internal methods.
- Advancements in transducer miniaturization enable intracorporeal ultrasound during laparoscopy.
Purpose of the Study:
- To present the principles of ultrasonography.
- To evaluate the utility of laparoscopic intracorporeal ultrasound (LICU) in surgical diagnostics and anatomy delineation.
Main Methods:
- Review of ultrasonography principles.
- Application of LICU in laparoscopic procedures for liver tumor diagnosis, hepatobiliary anatomy assessment, and common bile duct stone detection.
Main Results:
- LICU demonstrated high accuracy in identifying suspected liver tumors (75/85 patients).
- LICU provided valuable anatomical information during laparoscopic cholecystectomy and accurately detected common bile duct stones.
- LICU showed potential in preoperative staging of pancreatic malignancy.
Conclusions:
- Laparoscopic intracorporeal ultrasound is a valuable tool for liver tumor diagnosis and surgical guidance.
- LICU enhances the safety and accuracy of laparoscopic procedures, particularly in hepatobiliary surgery.
- Further applications of LICU are anticipated as surgical experience grows.

01:17Ultrasonography
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

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...
