This study aimed to assess the status of abdominal wall adhesions resulting from prior surgeries and their impact on the outcomes of robotic surgery. We retrospectively reviewed clinical information, surgical outcomes, and the status of abdominal wall adhesions in patients who underwent gynecologic robotic surgery at Yamanashi Central Hospital, between April 2018 and March 2023. Abdominal wall adhesions were classified into seven locations and their presence was assessed at each site. Among the 768 cases examined, 196 showed the presence of abdominal wall adhesions. Notably, patients with a history of abdominal surgery exhibited a significantly higher incidence of abdominal wall adhesions than those without such surgical history, although no significant difference was observed in the frequency of adhesions in the upper left abdomen. Patients with a history of gynecologic, gastrointestinal, or biliopancreatic surgeries were more likely to have adhesions at the umbilicus or upper abdomen sites where trocars are typically inserted during robotic surgery. Although cases with abdominal wall adhesions experienced longer operative times than those without, there was no significant difference in estimated blood loss. In 13 cases (1.7%), adjustments in trocar placement were necessary due to abdominal wall adhesions, although none of the cases required conversion to open or conventional laparoscopic surgery. Abdominal wall adhesions pose challenges to minimally invasive procedures, emphasizing the importance of predicting these adhesions based on a patient's surgical history to safely perform robotic surgery. These results suggest that the robot's flexibility proves effective in managing abdominal wall adhesions.
