Laparoscopic surgery and its potential for medical complications.

ABSTRACT

Laparoscopic surgery is very popular among physicians and patients because this technique is associated with safety, shorter hospital stay, early return to normal activity, and cosmetic acceptance of the operative scar. Although the procedure involves minimal invasion and tissue damage, it has potentially serious complications, including cardiopulmonary effects that result mainly from hypercarbia and raised intraabdominal pressure caused by pneumoperitoneum. Absorbed carbon dioxide from the peritoneal cavity tends to cause acidosis. Leakage of the gas into tissue spaces may induce subcutaneous emphysema, pneumothorax, pneumomediastinum and pneumopericardium. Cardiac effects include arrhythmias, hypotension, cardiac arrest, gas embolism, pulmonary edema, and myocardial ischemia or infarction. Some of these effects, though rare, are serious and potentially fatal. Physicians should anticipate these problems in their patients undergoing laparoscopic procedures. This review discusses the technique of and physiologic considerations in laparoscopic surgery as well as its potential complications.
