Surgical laparoscopy & endoscopy
-
Laparoscopic cholecystectomy has become a widely used procedure. Upper abdominal surgery and particularly open cholecystectomy are known to be associated with marked declines in lung volume and a high risk of postoperative pulmonary complications. The pulmonary effects of laparoscopic cholecystectomy have not yet been studied. ⋯ There was no significant difference in loss of lung function according to age (p = 0.18), sex (p = 0.33), or smoking history (p = 0.58). Despite the marked loss in lung function in the immediate postoperative period, no major pulmonary complications occurred. We conclude that laparoscopic cholecystectomy, although associated with early loss of lung function, is a safe and effective procedure with an incidence of postoperative pulmonary complications much less than with open cholecystectomy.

Case ReportsHypercarbia during carbon dioxide gas insufflation for therapeutic laparoscopy: a note of caution.
During the past decade, the number of laparoscopic procedures performed in the United States, primarily with cholecystectomy, has increased phenomenally. We recently had a patient who developed hypercarbia and cardiovascular compromise during laparoscopic cholecystectomy. The cardiovascular compromise was caused by mechanical factors directly related to increasing intra-abdominal pressures affecting ventilation and venous return as well as the absorption of carbon dioxide (CO2) into the circulation, leading to acidosis and further depression of the cardiopulmonary system. Cardiovascular compromise can be avoided with early recognition of increased end-tidal CO2 concentrations and by preventing intra-abdominal pressures from exceeding 16 mm Hg.

In selected patients outpatient laparoscopic cholecystectomy is safe and significantly reduces hospitalization charges.
The safety of laparoscopic cholecystectomy has been demonstrated through its increased use, and we have performed 114 of these operations as outpatient procedures. These patients have done well and hospitalization charges have been reduced substantially. Of 622 laparoscopic cholecystectomies performed from November 1989 to March 1991, 114 were done on an outpatient basis if the patients were generally healthy, lived nearby, and the operative procedure was uneventful. ⋯ D., A. A.), 43 were performed as outpatients using the above selection criteria. 44 were held for 23-h observation, and 13 were inpatients. The average hospital charge for 377 uncomplicated morning-admitted inpatient standard cholecystectomy patients was $4,250.00, compared with $2,293.02 for 106 outpatient laparoscopic cholecystectomy patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Two sets of experiments were conducted to determine whether the potential hazards of secondary sparking and distal tissue burns are a serious risk for surgeons using monopolar electrosurgery during laparoscopy. The results indicate that secondary sparking poses little threat, whereas distal burns are very likely, given certain tissue parameters that force the entire electric current through narrow structures.
