Clinical analysis of complications after laparoscopic radical gastrectomy for patients over 70 years old with low abdominal pressure

Abstract

Objective: To explore the safety and reliable of low pressure laparoscopy in old patients, and the advantage over conventional pressure laparoscopy. Methods: Sixty-six patients(≥70 year) with gastric cancer from 2014.4 to 2017.4 were enrolled, and they were divided into three groups randomly. The value of Ejection Fraction (EF), central venous pressure (CVP), B-type natriuretic peptide (BNP), O(2) pressure, CO(2) pressure, complications of three groups were compared and analysis. Results: There was no differences between low-pressure laparoscopic group, conventional laparoscopic group and laparotomy group in age, gender, EF, oxygen pressure, CVP (P>0.05). But the postoperative BNP, intraoperative carbon dioxide pressure of low-pressure laparoscopic group were significantly better than those of the other two groups. Compared with the conventional laparoscopic group and the laparotomy group, the low-pressure laparoscopic group has fewer postoperative complications (P=0.027, <0.05), especially in postoperative pulmonary infection (P=0.044, <0.05). Conclusion: The low pressure laparoscopy has decreased the stimulation of surgery to old patients, and reduced the postoperative complications. All this results demonstrate that the low pressure laparoscopy to old patients is safety and reliable.
