Impact of Gas(less) Laparoscopy and Laparotomy on Peritoneal Tumor Growth and Abdominal Wall Metastases

Abstract

The following conclusions can be made: 1) that direct contact between solid tumor and the port site enhances local tumor growth, 2) that laparoscopy is associated with less intraperitoneal tumor growth than laparotomy, and 3) that insufflation of CO2 promotes tumor growth at the peritoneum and is associated with greater abdominal wall metastases than gasless laparoscopy.
