Abstract:

Objective

To evaluate the application value of water-sealed bottle with continuous gas exhaust to maintain pneumoperitioneal pressure in laparoscopic surgery.

Methods

From May 13, 2016 to August 10, 2017, clinical data of 54 patients undergoing transperitoneal laparoscopic surgery using water sealed bottle with continuous gas exhaust to maintain pneumoperitioneal pressure (the water sealed bottle group), and 54 cases of transperitoneal laparoscopic surgery using conventional gas exhaust (conventional group) were retrospectively analyzed according to different surgical methods, such as radical resection of prostate cancer, partial nephrectomy and radical nephrectomy of kidney cancer. The times of laparoscopic lens cleaning, operation time, intraoperative blood loss, days of postoperative drainage and the length of postoperative hospital stay were statistically compared between the two groups.

Results

In the water-sealed bottle group, the times of laparoscopic lens cleaning during radical prostatectomy, partial nephrectomy and radical nephrectomy were significantly less than that in the conventional group (all P<0.001). The operation time of three types of surgeries significantly differed between the water-sealed bottle and conventional groups (P=0.015, 0.046, 0.024). The intraoperative blood loss, days of postoperative drainage and the length of postoperative hospital stay of three types of operations did not significantly differ between two groups.

Conclusions

The water sealed bottle with continuous gas exhaust can maintain pneumoperitioneal pressure, discharge the frog and gas intraoperatively, maintain the working pressure stable, significantly enhance the surgical efficiency and shorten the operation time of laparoscopic surgery. It is a convenient and economical surgical approach, which deserves widespread application in different types of laparoscopic surgeries.
