“…Intraoperative US has been also useful in bile duct surgery, in catheterizing and draining bile ducts, and in performing puncture/biopsy of tumors. 32 IOUS is an additional procedure in surgical operations, which leads to an increase in operative time. However, by allowing a rapid identification of small lesions, a more precise staging of tumors, guiding resections that would otherwise be performed blindly, and by making associated surgical procedures feasible, the end result is actually a shortening of overall operative time.…”

Intraoperative ultrasonography of liver, bile ducts and pancreasThe use of intraoperative ultrasonography (IGUS) to evaluate liver, bile ducts and pancreatic disease, as compared to the results of preoperative ultrasonography and CT, is discussed. Forty-two patients who underwent abdominal surgery for suspected hepatobiliary and/or pancreatic disease were studied. The intraoperative study was carried out with a portable apparatus (Aloka 500, Japan), using 5.0 MHz and 7~5 MHz linear sterile transducers. The main indications for IGUS were the search for and/or evaluation of primary hepatic masses,hepatic abscesses or metastases, obstructive jaundice, or neuroendocrine tumors. In 15 cases (38.5 percent) from the hepatobiliary group and in 7 cases (58.3 percent) from the pancreatic group, a difference between preoperative and intraoperative findings was observed. The main difference was observed in relation to the number and size of hepatic and pancreatic lesions. The relationship between the lesions and the vascular structures was evaluated through IGUS. The method was also used to guide surgical procedures such as biopsies, the alcoholization of nodules, and the drainage of abscesses. IGUS plays an important role in detecting small hepatic and pancreatic nodules, in the assessment of anatomical relationships between the lesions and the vascular structures, and in the performance of interventionist procedures.

“…The most common physical effect that may be generated by ultrasound is heat. Ultrasound has been used in different medical branches and for a variety of applications [13][14][15][16][17][18][19][20][21][22] and no confirmed reports of adverse effects due to the use of ultrasound in patients have been presented.…”

Minimally invasive techniques enable diagnostics and surgery to be performed through a small incision. This greatly reduces the damage to healthy tissue leading to faster recovery times for the patient. However, the surgeon is deprived of the sensory feedback available with normal surgical techniques. Miniaturised sensors can provide this information about location, diagnostics and the treatment. This application severely limits the size of the device, with some catheters being less than 1 mm in diameter. Catheters are usually defined in multiples of 1/3 mm or 1 french. Further important issues are bio-compatibility, safety and the ability of the sensor to withstand the working environment. Sensors able to meet these demands are improving the efficiency of operations and are opening new opportunities for minimally invasive techniques.
