Acute renal failure following laparoscopic cholecystectomy: A case report

The carbon dioxide (CO2) pneumoperitoneum of laparoscopic surgery is a complex physiologic event associated with neuroendocrine, respiratory, cardiovascular, and renal disturbances, as well as compromised organ blood flow. A case is presented of a 67-year-old man with a history of chronic renal failure, renal tubular acidosis, and hypertension, who underwent an uneventful elective laparoscopic cholecystectomy that included 75 minutes of CO2 pneumoperitoneum of 15 mmHg pressure. Postoperatively, the patient developed acute renal failure from which he recovered within 2 weeks. In the absence of other evident precipitating factors, we suspect that the CO2 pneumoperitoneum played a causal role in the development of his acute renal failure. The potential seriousness of the physiologic insult of conventional CO2 pneumoperitoneum suggests that "minimal access" surgery is not necessarily "minimally invasive."
