Validation of the NASA-TLX Score in Ongoing Assessment of Mental Workload During a Laparoscopic Learning Curve in Bariatric Surgery.

Background: Fatigue and mental workload are directly associated with high-complexity tasks. In general, difficult tasks produce a higher mental workload, leaving little opportunity to deal with new/unexpected events and increasing the likelihood of performance errors. The laparoscopic Roux-en-Y gastric bypass (LRYGB) learning curve is considered to be one of the most difficult to complete in laparoscopic surgery.

Neoadjuvant intraperitoneal chemotherapy with paclitaxel for the radical surgical treatment of peritoneal carcinomatosis in ovarian cancer: a prospective pilot study.

Purpose: The admitted benefits of intraperitoneal chemotherapy during postoperative administration for the treatment of peritoneal carcinomatosis from ovarian origin are limited by their associated morbidity and restricted diffusion by the presence of multiple intra-abdominal adherences. The purpose of the study was to evaluate the security, effectiveness, and cytoreduction optimization of intraperitoneal paclitaxel administration previously to radical surgery/peritonectomy/HIPEC (hyperthermic intraoperative intraperitoneal chemotherapy) either in monotherapy or combined with intravenous carboplatin.

Methods: Prospective pilot study of 10 patients with ovarian peritoneal carcinomatosis in stage IIIc-FIGO without previous treatment.

Treatment of peritoneal carcinomatosis from ovarian cancer. Present, future directions and proposals.

Peritoneal carcinomatosis, considered years ago as a final stage of unresectable cancer, can now be managed with curative intention by means of a radical cytoreductive surgical procedure with associated peritonectomy and intraperitoneal chemotherapy, as described by Sugarbaker. Malignant neoplasms such as mesothelioma and pseudomyxoma peritonei, ovarian and colon cancer nowadays are experiencing some new therapeutical approaches. Higher survival rates can be reached in ovarian cancer, which is commonly diagnosed in the presence of peritoneal carcinomatosis, using an optimal cytoreductive radical surgery with intraperitoneal chemotherapy.

Survival of patients receiving a liver transplant for hepatocellular carcinoma, and risk of tumor recurrence.

Objective: The goal of this research has been to evaluate the survival, in long and short term, of the patient receiving liver transplant for hepatocellular carcinoma (HCC), the risk of post-transplant tumor relapse and factors related to this complication.

Design: Retrospective study of a consecutive series of patients having had liver transplant for HCC.

Patients And Methodology: Transplant patients for HCC from 1989 to November 2003.
