Intraoperative and laparoscopic ultrasound

Area of Science:

• Surgical oncology
• Medical imaging
• Gastrointestinal surgery

Background:

• Intraoperative ultrasound (IOUS) aids surgeons in managing intra-abdominal diseases.
• Malignancies of the liver, pancreas, and upper gastrointestinal tract are common indications for IOUS.
• IOUS is particularly valuable in laparoscopic surgery, compensating for the lack of tactile feedback.

Purpose of the Study:

• To highlight the significance of intraoperative ultrasound in surgical decision-making.
• To emphasize the role of IOUS in detecting small lesions in solid organs.
• To underscore the increasing importance of IOUS proficiency for surgeons performing laparoscopic procedures.

Main Methods:

• Intraoperative ultrasound application during celiotomy and laparoscopy.
• Comparison of IOUS sensitivity with preoperative imaging studies.
• Evaluation of IOUS impact on surgical treatment plans, especially resectability.

Main Results:

• IOUS is the most sensitive method for detecting small intraparenchymal lesions in the liver, pancreas, and other solid organs.
• IOUS significantly alters intraoperative treatment plans in a substantial percentage of cases, particularly regarding tumor resectability.
• IOUS enhances surgical guidance during laparoscopic procedures, overcoming limitations in palpation.

Conclusions:

• Intraoperative ultrasound is essential for optimizing the management of intra-abdominal malignancies.
• The superior sensitivity of IOUS compared to preoperative imaging leads to improved treatment strategies.
• Mastery of intraoperative ultrasound is increasingly vital for surgeons utilizing laparoscopic approaches for intra-abdominal diseases.
