A technique for real-time digital measurements in laparoscopic surgery.

BACKGROUND: The current techniques for the measurement of intracorporeal targets in laparoscopic surgery are relatively cumbersome and imprecise. METHODS: A structured light technique was used to obtain the length and width of two defects and an object in a laparoscopic training box. These measurements were compared against two current and standard laparoscopic techniques of intracorporeal measurement: the introduction of a plastic ruler and the use of an opened end of a laparoscopic instrument to approximate 2 cm. The time needed to measure the defects and object was recorded. RESULTS: Structured light-derived measurements were closest to the criterion standard, followed by plastic ruler measurements, then by instrument-end measurements. Digital measurements were quickest, followed by the instrument-end method, then by the plastic ruler. CONCLUSIONS: This report describes a novel structured light technique for laparoscopic measurement of intracorporeal targets capable of producing results superior to those of current techniques.

Laparoscopic adrenalectomy for pheochromocytoma. A comparison to aldosteronoma and incidentaloma.

BACKGROUND: Laparoscopic adrenalectomy is a safe and effective treatment for most surgical diseases of the adrenal gland. However it has been suggested that catecholamine effects associated with pheochromocytoma render the laparoscopic approach a more challenging and a more morbid procedure. The purpose of this study was to compare the operative characteristics and outcomes of laparoscopic adrenalectomy for pheochromocytoma to those of aldosteronoma and incidentaloma. METHOD: Patient records and operative reports were retrospectively reviewed for demographics, diagnoses, operative management, and outcomes for patients undergoing laparoscopic adrenalectomy between June 1994 and July 2002 at two academic medical centers. A total of 74 patients were included and analyzed by diagnosis. Differences were considered statistically significant at p < 0.05. RESULTS: Twenty-eight patients with pheochromocytoma, 27 with aldosteronoma, and 19 with incidentally discovered nonfunctioning adrenal masses underwent laparascopic adrenalectomy. Patients undergoing resection for pheochromocytoma trended toward more operative blood loss (150 ml) compared to aldosteronoma (88 ml) and incidentaloma (75 ml). Eight patients were converted to an open procedure for a 10.8% conversion rate. The mean operative time was 171 min and there was a 10.8% perioperative complication rate. The mean hospital stay was 3.4 days. These results were not statistically significant between diagnostic groups. CONCLUSION: Despite concern about increased operative times and morbidity associated with pheochromocytoma, our experience supports that laparoscopic adrenalectomy may be performed as safely as, and achieve outcomes similar to, those for other diseases.

Intraabdominal abscess following open and laparoscopic appendectomy in the pediatric population.

BACKGROUND: Studies comparing intraabdominal abscess (IAA) rates following laparoscopic appendectomy (LA) and open appendectomy (OA) have shown conflicting results. METHODS: The charts of 324 children undergoing appendectomy were reviewed retrospectively to examine the incidence of IAA. RESULTS: Of the 324 appendectomies, 204 (63.0%) were completed laparoscopically and 119 (36.7%) were performed open. The conversion rate was 0.2% (1/324). Of the 15 (4.6%) IAAs, 7 occurred in the LA group (3.4%) and 8 occurred in the OA group (6.7%) [p = not significant (NS)]. The incidence of IAA for perforated appendicitis for LA was 15% (7/46) and that for OA was 10% (7/70) (p = NS). CONCLUSION: This study demonstrates no statistically significant difference in the rate of IAA among children following LA and OA. LA can be performed for perforated appendicitis without increasing the risk of IAA.
