Laparoscopic cholecystectomy in a freestanding outpatient surgery center was evaluated. Fifty-five patients undergoing laparoscopic cholecystectomy during a 10-month period from December 1992 to October 1993 were included in this study. There were 10 males and 45 females, with a mean age of 42 years. All patients had a history consistent with biliary colic. Forty-nine patients had documentation of cholelithiasis by ultrasonography, 3 had documentation of cholelithiasis by other diagnostic procedures, and 3 had a diagnosis of biliary dyskinesia. The mean surgery time was 75 min, with a range of 43-145 min. Fifty-four intraoperative cholangiography attempts were made, and 81% were successful. In 19%, intraoperative cholangiography was unsuccessful secondary to a small cystic duct. Fifty of the patients (90%) in this study were discharged from the surgery center without significant sequelae. Four patients were admitted to the hospital postoperatively, 1 for bradycardia, 1 for nausea, 1 for i.v. antibiotics secondary to purulent cholecystitis, and 1 for inability to maintain an adequate oxygen saturation. Another patient was admitted 1 week postoperatively for right upper quadrant pain. After a negative hepatobiliary scan, this patient was discharged without sequelae. The average facility charge of laparoscopic cholecystectomy in this series was $2300, compared with the average charge of $6500 in our community hospital. We conclude that laparoscopic cholecystectomy can be performed safely and cost effectively in a freestanding outpatient surgery center with proper patient selection.

The pathophysiology of seroma formation has yet to be determined. Therefore, the present study was undertaken to calculate the incidence of postoperative seromas after definitive breast cancer operations utilizing electrocautery dissection. Additionally, we attempted to identify risk factors associated with seroma development and to examine seroma formation in relation to operative procedure. A retrospective review of 252 breast cancer operations was undertaken. Patients were subdivided by operative procedure: modified radical mastectomy (MRM; n = 148), breast preservation with axillary node dissection (n = 64), or MRM with immediate reconstruction (n = 40). Electrocautery was used in development of skin flaps. Seromas developed in 39 of the 252 operations for an incidence of 15.5 per cent. Seroma formation was significantly lower in those patients receiving MRM with immediate reconstruction than in those receiving MRM (2.5% vs 19.6%; P = 0.009) and tended to be lower than for patients receiving breast preservation with axillary node dissection (14.06%; P = 0.052). Neoadjuvant chemotherapy was performed in 18 patients, of whom 6 developed seromas ( P = 0.030). The incidence of postoperative seromas was low despite the use of electrocautery. An association of postoperative seromas with neoadjuvant chemotherapy was noted. Additionally, it appears that immediate reconstruction may reduce the incidence of postoperative seromas, presumably by filling the dead space in the chest wall.
