WHAT IS AN EXPLORATORY LAPAROTOMY?. An exploratory laparotomy is a minimally invasive surgical procedure involving the opening of the abdominal cavity and examination of the abdominal organs. It is used in for the diagnosis of intra-abdominal diseases through direct inspection of intra-abdominal organs as well as pelvic organs. . . development. . process. kellee. . santiago. . & robin . hunicke. er. . .. . .. . .. . exploratory. are you . experienced?.
