Cerebral monitoring of somatosensory evoked potentials during carotid surgery: a review of 100 cases.

The purpose of this study was to evaluate immediate and middle-term results of surgical carotid artery revascularization (CAR) with cerebral monitoring of intraoperative somatosensory evoked potentials (SEPs). Between 1998 and 2004, a total of 100 CARs in 86 patients were performed under general anesthesia with SEP monitoring. A shunt was inserted if SEP amplitude decreased by 50% or latency time increased by 10%.

Major hepatectomy for hilar cholangiocarcinoma type 3 and 4: prognostic factors and longterm outcomes.

Background: Radical operation for hilar cholangiocarcinoma, including major hepatectomy with vascular resection, seems to improve longterm survival. This study retrospectively evaluates several prognostic risk factors that can influence survival after resection of types 3 to 4 Klatskin tumors.

Study Design: Between 1984 and 2003, 59 patients (36 men and 23 women) with types 3 to 4 hilar cholangiocarcinoma underwent liver resection with curative intent.

Ex vivo sentinel lymph node study for rectal adenocarcinoma: preliminary study.

Intraoperative sentinel lymph node (SLN) detection has been reported for colon cancer, but no study has focused on rectal cancer. Only an ex vivo technique can be performed easily in this location. We evaluated SLN detection using blue dye injection in patients with rectal adenocarcinoma.

[Echoendoscopic ultrasound/fine needle aspiration of an hepatic cystadenoma].

The diagnosis of hepatic cystadenoma is difficult with the conventional radiologic imaging. When these hepatobiliary cystic tumors are located in the left liver, Echoendoscopic ultrasound/Fine needle aspiration can help in the diagnosis by showing high levels of cystic CEA and CA 19-9 in a mucinous fluid. Definitive histological evaluation is assessed by the examination of the operative specimen.

Hepatectomy plus intraoperative radiofrequency ablation and chemotherapy to treat technically unresectable multiple colorectal liver metastases.

Background: Results and indications of intra-operative radiofrequency (RF) ablation of liver metastases (LM) are not well defined in the literature.

Aim: To appreciate the survival rate of patients with strictly unresectable LM (defined on technical but not oncological criteria) when undergoing liver resection plus RF, along with optimal systemic chemotherapy.

Patients And Methods: Sixty three patients with technically unresectable LM (either >5, or bilateral with no sparing of at least one sector of the liver, or with tumor proximity to central major vascular structures) were treated.

Treatment of peritoneal carcinomatosis from colorectal cancer: impact of complete cytoreductive surgery and difficulties in conducting randomized trials.

Background: Colorectal peritoneal carcinomatosis (PC) is a frequent and very lethal event. However, cure may be possible with maximal cytoreductive surgery associated with early postoperative intraperitoneal chemotherapy (EPIC).

Methods: Between 1996 and 2000, we conducted a two-center prospective randomized trial comparing EPIC plus systemic chemotherapy with systemic chemotherapy alone, both after complete cytoreductive surgery of colorectal PC.

Local recurrences after intraoperative radiofrequency ablation of liver metastases: a comparative study with anatomic and wedge resections.

Background: The indications and results of intraoperative radiofrequency ablation (RFA) of liver metastases (LMs) are not well defined in the literature and have never been compared with those of hepatectomy. The aim of the study was to appreciate the local recurrence rate of RFA in comparison with anatomic and wedge resection.

Methods: Eighty-eight patients with technically unresectable LMs were treated with curative intent.

Evolution of missing colorectal liver metastases following inductive chemotherapy and hepatectomy.

Background: A dramatic response to chemotherapy in some patients with multiple bilateral and initially unresectable liver metastases (LM) from colorectal cancer sometimes leads to their disappearance from imaging studies. Our study was aimed at assessing the evolution of these metastases when they were also not found during liver surgery.

Patients: Among 104 hepatectomized patients for colorectal LM in 4 years, 15 patients were retrospectively eligible.
