Prospective, blinded comparison of laparoscopic ultrasonography vs. contrast-enhanced computerized tomography for liver assessment in patients undergoing colorectal carcinoma surgery

Abstract

Laparoscopic ultrasonography of the liver at the time of primary resection of colorectal cancer yields more lesions than preoperative contrast-enhanced computerized tomography and should be considered for routine use during laparoscopic oncologic colorectal surgery.

Laparoscopic ultrasound-guided biopsy in upper gastrointestinal tract cancer patients

“…Use of staging laparoscopy has been evaluated in all types of upper gastrointestinal malignancies [1], whereas concomitant use of LUS has mainly been reported in patients with liver and pancreatic tumors [4][5][6][7]. There are only limited data on the use of laparoscopic biopsies during the evaluation of UGIC patients, and the lack of LUS-guided biopsy reports may be due to the more recent introduction of dedicated biopsy systems [3], and the fact that the procedure requires ultrasound experience and even then may prove technically difficult to perform.…”

The role of staging laparoscopy for intraabdominal cancers: an evidence-based review

“…Studies comparing open intraoperative ultrasound with laparoscopic ultrasound and preoperative CT scanning for colorectal metastases have shown that the yield is best with open intraoperative ultrasound, followed by laparoscopic ultrasound (98% yield; one detected lesion less than with open intraoperative ultrasound) and CT scan (78% yield) [61]. Furthermore, SL and laparoscopic ultrasound have better sensitivity than noninvasive imaging studies for the detection of nodal metastases (94% for laparoscopic ultrasound vs 18% for preoperative imaging) [62].…”

Der laparoskopische Ultraschall

“…die Metastasensuche in Analogie zur intraoperativen Sonographie und bimanuellen Palpation der Leber beim offenen Eingriff an Bedeutung [7,37] und scheint der präoperativen Bildgebung weiterhin überlegen zu sein [25].…”
