BACKGROUND: Laparoscopic-assisted colectomy is an emerging technology for patients with cancer, polyps, inflammation, and other types of pathologic conditions. While previous studies have shown better outcomes for laparoscopic cholecystectomies when surgeons perform more procedures, there is no information on the relationship between surgeon volume and outcomes for laparoscopic-assisted colectomy. OBJECTIVE: To evaluate whether better clinical outcomes are found for surgeons who perform higher numbers of laparoscopic-assisted colectomies and whether such a relationship, if it exists, applies to both intraoperative and postoperative outcomes. DESIGN: Analysis of a data set of 1194 patients, operated on by 114 surgeons, from a prospective registry sponsored by the American Society of Colon and Rectal Surgeons, from May 1991 to October 1994. MAIN OUTCOME MEASURES: Completion rate, intraoperative and postoperative complications, and length of hospital stay. RESULTS: In 75% of cases, surgery was completed laparoscopically, with no difference between high-volume surgeons (> or = 40 cases) and low-volume surgeons. Length of stay (average, 6 days) did not vary according to surgeon volume. Postoperative complications occurred in 15% of cases, with a significantly lower rate for high-volume surgeons (10% vs 19%; P < .001). Intraoperative complications occurred in 5% of cases, with a nonsignificant trend toward a lower rate for high-volume surgeons (3.7% vs 6.3%). A multivariate regression analysis, adjusting for type of disease (cancer vs inflammation vs polyps) and for level of difficulty of the procedure (high vs low) showed that for high-volume surgeons there is a lower probability of both intraoperative complications (adjusted odds ratio, 0.56; 95% confidence interval, 0.32-0.97; P = .04) and postoperative complications (adjusted odds ratio, 0.48; 95% confidence interval, 0.34-0.68; P < .001). CONCLUSIONS: There is a learning curve for laparoscopic-assisted colectomy with respect to intraoperative and postoperative outcomes. As with other laparoscopic procedures, surgeons who perform higher volumes of laparoscopic-assisted colectomy have lower rates of intraoperative and postoperative complications.
The aim of this study was to estimate and compare the costs of open right hemicolectomy (ORHC) versus laparoscopically assisted right hemicolectomy (LARHC) performed for cancer. A retrospective cost analysis of 61 consecutive patients operated on between January 1992 and August 1994 for right-sided colonic cancer by either LARHC (n = 28) or ORHC (n = 33) was performed. The analysis focused on the cost (in Australian dollars) incurred from the date of operation to the date of discharge. LARHC was significantly more expensive than ORHC (total cost LARHC $9064, ORHC $7881; p < 0.001). LARHC was associated with a significantly longer operating room utilization time (LARHC 261 minutes, ORHC 203 minutes; p < 0.001) and a greater cost of disposables (LARHC $854, ORHC $189; p < 0.001). This study demonstrates no cost benefit for LARHC compared to ORHC when performed for cancer.
Telemedicine offers significant advantages in bringing consulting support to distant colleagues. Our aim in this study was to evaluate the role of telementoring in the training of advanced laparoscopic surgical procedures. Student surgeons received a uniform training format to enhance their laparoscopic skills and intracorporeal suturing techniques and specific procedural training in laparoscopic colonic resections and Nissen fundoplication. Subsequently, operating rooms were equipped with three cameras. A telestrator (teleguidance device), instant replay (to critique errors), and CD-ROM programs (to provide reference information) were used as intraoperative, educationally assistant tools. In phase 1, four colonic resections were performed with the mentor in the operating room (group A), and four colonic resections were performed with the mentor on the hospital grounds but not in the operating room (group B). The voice and video signals were received at the mentor's location using coaxial cable. In phase 2, two Nissen fundoplications were performed with the mentors in the operating room (group C), and two Nissen fundoplications were performed with the mentors 5 miles away from the operating room (group D) using existing land lines at the T1 level. We found no differences in the performances of the surgeons or the outcomes of the operations between groups A and B and groups C and D. Intraoperative problems were tackled effectively. Preliminarily, we conclude that the telementoring concept is potentially a safe and cost-effective option for advanced training in laparoscopic operations. Further investigation is necessary before routine transcontinental patient applications are attempted.
