Advanced techniques and equipment in laparoscopic surgery offer advantages over open surgery, expanding the application of this minimally invasive procedure to a wide range of abdominal operations that used to be performed as an open procedure. Laparoscopic surgery is performed in the closed abdominal cavity in which the space is limited. To create a working space in the abdominal cavity, an artificial pneumoperitoneum is established and multiple ports are placed for the introduction of various laparoscopic instruments. Unlike open surgery in which the incision is made just above the target organ, laparoscopic access is made away from the area of dissection, with the instruments triangulated around the target organ within the abdomen. This fundamental difference in approach between the open and laparoscopic procedures may lead to peculiar postoperative complications after laparoscopic surgery, which may be present away from the target organ or in the abdominal wall, and be easily missed on postoperative imaging studies. These complications include port-related direct organ injuries, such as abdominal organ or vascular injury; abdominal wall complications related to laparoscopic port insertion such as vascular injury, infection, and hernia; abdominal wall complications related to specimen removal, such as port site tumor seeding and endometriosis; and complications related to gas insufflation. The radiologist plays an important role in the diagnosis of complications after laparoscopic surgery, and therefore should be familiar with the features of such complications on imaging scans in the era of laparoscopic surgeries.
