Telepathy: maximizing resident exposure to surgical pathology decision making.

BACKGROUND: General surgery residents are often not present for the critical intraoperative discussion between surgeon and pathologist regarding surgical pathology findings. METHODS: A prospective pilot study analyzed general surgery resident exposure to surgical pathology. Thereafter, an operating room was equipped to view frozen section images in real time and verbally communicate with the pathologist (TelePATHy). Total operative cases, cases using frozen sections, and use of TelePATHy were recorded. RESULTS: Most residents (78%) reported they were exposed to frozen-section surgical pathology < or =10% of the time. Overall, 202 operations were performed over the 123-day period. Forty-four cases had frozen-section specimens. General surgery residents were present for 40 cases. TelePATHy was successfully used in 32 cases (80%). CONCLUSIONS: General surgery resident exposure to intraoperative pathology findings increased from a reported < or =10% to an observed 80%. TelePATHy is a novel intraoperative tool capable of maximizing the intraoperative experience of the surgical resident.

Laparoscopic localization and resection of insulinomas.

HYPOTHESIS: Laparoscopic localization and resection of insulinomas are feasible and safe and may decrease morbidity and the length of hospitalization. DESIGN: Case series identified through retrospective medical record review. SETTING: Mayo Clinic, Scottsdale, Ariz, and Rochester, Minn, a single-institution tertiary care medical center. PATIENTS: Nine patients (6 men and 3 women; mean age, 54 years) who underwent attempted laparoscopic insulinoma resection between September, 1997, and April, 2002. INTERVENTIONS: Laparoscopic localization and resection of insulinoma tumors of the pancreas. MAIN OUTCOME MEASURES: Intraoperative complications, conversion to open laparotomy, and length of hospitalization. RESULTS: Preoperative localization was successful in 5 patients (56%). Four conversions to open exploration were required because of an inability to identify the tumor (n = 3) or to perform a safe laparoscopic resection owing to proximity to the portal vein (n = 1). Laparoscopic intraoperative ultrasonography facilitated identification of lesions (mean tumor size, 2.1 cm) in 4 (80%) of 5 patients; 3 patients underwent successful laparoscopic resection. Average hospital stay was shorter after laparoscopic resection (4.5 vs 7.0 days in uncomplicated cases). At follow-up (mean, 29 months; range, 3-57 months), 1 patient who underwent laparoscopic enucleation had recurrent hypoglycemia. CONCLUSIONS: Laparoscopic localization and resection of insulinomas are feasible and safe. Laparoscopic ultrasound aids successful insulinoma localization and laparoscopic resection. Preoperative localization is not required, but previous knowledge of tumor location helps focus intraoperative ultrasound and limit pancreatic mobilization. Excluding patients with pancreatic leaks (observed in both groups), hospital stay and time to recovery may be shortened by using laparoscopic insulinoma resection.

Robot-assisted laparoscopic cholecystectomy: initial Mayo Clinic Scottsdale experience.

OBJECTIVE: To review a single institution's experience with robot-assisted laparoscopic cholecystectomy. PATIENTS AND METHODS: We reviewed retrospectively all cholecystectomies performed with the assistance of a surgical robot at the Mayo Clinic in Scottsdale, Ariz, from October 2002 to July 2003. Cholanglograms were obtained intraoperatively for patients with elevated results on liver function tests. The gallbladder was removed by the surgeon with the use of the robot. A surgical assistant at the operating table exchanged instruments in the robot arms and applied clips when needed. Total operating time, assembly time of the robot, complications, and postoperative course were evaluated. RESULTS: Nineteen patients underwent robot-assisted laparoscopic cholecystectomy; 16 had symptomatic cholelithiasis, 2 had gallbladder polyps, and 1 had acute cholecystitis. Of the 19 surgeries, 16 were completed successfully with robotic assistance. In 3 consecutive patients, a mechanical problem occurred with the robot; however, all procedures were completed laparoscopically. The mean set-up time, including patient positioning and preparation and robotic installation, was 28.1 minutes. The mean +/- SD operating time was 82.3+/-17.9 minutes without a cholanglogram and 102+/-20.9 minutes with a cholanglogram. There were no complications and no conversions to an open procedure. CONCLUSION: Robotic surgery offers many potential advantages, including surgeon comfort, elimination of surgeon tremor, improved imaging, and increased degrees of freedom of the operative Instruments, compared with conventional laparoscopic surgery. However, patient outcomes and operative costs need to be evaluated further.

Laparoscopic adrenalectomy for pheochromocytoma.

OBJECTIVE: To determine the safety and results of laparoscopic resection of benign pheochromocytomas. PATIENTS AND METHODS: We retrospectively reviewed the medical charts of all patients who underwent laparoscopic adrenalectomy for benign pheochromocytomas at all 3 Mayo Clinic sites between January 1, 1992, and December 31, 2001. Demographics, comorbidities, clinical presentation, imaging studies, biochemical findings, operative intervention, and outcome were examined. Long-term follow-up was obtained via chart review and/or by direct telephone contact with the patient or a relative. RESULTS: Twenty-four women and 23 men with a mean age of 53.1 years (range, 16-81 years) underwent attempted laparoscopic resection of pheochromocytomas. In 5 patients, the procedure was converted to open laparotomy because of bleeding (2), inadequate exposure (2), and adhesions (1). The mean tumor size was 4.3 cm. The mean operative time (181.8 vs 1405 minutes; P = .03), mean hospital stay (6.00 vs 2.64 days; P < .001), and mean blood loss (340 mL vs 80 mL; P < .001) were greater in patients who underwent open laparotomy vs those who underwent laparoscopic resection. All specimens were classified as benign. The mean follow-up was 41 months (range, 10-89 months). No patients experienced a recurrence or developed metastatic disease. CONCLUSIONS: In light of surgical and anesthesia expertise, laparoscopic resection of benign pheochromocytomas is safe and effective with resultant short hospital stays. A low threshold to convert to an open procedure reduces operative times and decreases potentially serious complications. Although there have been no recurrences to date, long-term follow-up is required for all patients, especially those with hereditary forms of pheochromocytomas.

The development of a laparoscopic donor nephrectomy program in a de novo renal transplant program: Evolution of technique and results in over 200 cases.

BACKGROUND AND OBJECTIVES: In 1999, our institution began a kidney transplant program with collaboration between the departments of General Surgery/Transplantation and Urology. From the onset, donor nephrectomies were performed laparoscopically and are currently the domain of Urology, which had no prior laparoscopic experience before this undertaking. We reviewed our experience. METHODS: A database of our experience was kept prospectively from June 1999 to November 2004. Records of both donors and recipients were reviewed. Special attention was directed toward our changes in technique and their relationship to outcomes, with emphasis on graft extraction and overall complication rates. RESULTS: We reviewed the records of 205 consecutive procedures. We report excellent donor outcomes, including mean operative time (112 minutes), estimated blood loss (120 mL), and length of stay (2.3 days). Complication (14.1%) and open conversion (1.5%) rates were low. For the recipients, early (98.0%) and 1-year (94.7%) graft survival, and ureteral ischemia (2.4%) rates were also appropriate with contemporary experience. CONCLUSIONS: We report our results on laparoscopic donor nephrectomy in a de novo renal transplant program. Because of this experience, we have ventured into other horizons of urologic laparoscopy and currently produce enough volume to support a laparoscopic fellowship. We feel that a productive donor nephrectomy program can enhance urologic laparoscopic programs and should be taken advantage of when available.
