Standard Pressure Laparoscopic Cholecystectomy, SPLC；12-16mmHg，as the standard for cholecystectomy, can lead to about 15% of pulmonary atelectasis.~According to literature, Low Pressure Laparoscopic Cholecystectomy, LPLC；8-10mmHg is thought to probably decrease cardio-pulmonary related complications and postoperative pain. However, most of the existing study have combined population with all age scale, bringing bias to the result. Our study aim to evaluate the potential pulmonary benefit of low pressure laparoscopic cholecystectomy in elderly or patients accompanied with cardio-pulmonary disorders.
