Laparoscopic management of gastric gastrointestinal stromal tumors: A retrospective 10-year single-center experience

Figure 2 Operative positions and puncture trocars setting. The surgeon stood on the patient’s left side with the assistant on the patient’s right side. The laparoscopist stood between the patient’s legs. A 12-mm trocar was inserted below the umbilicus, and used as the laparoscope port. One 10-mm trocar was placed 2 cm from the intersection of the right side of the outer rectus and under the costal margin was used as the dominant hand port. One 5-mm trocar was placed 2 cm from the intersection of the right side of the outer rectus and the umbilicus. Two additional 5-mm trocars were placed in the contralateral side, including a third (white circle) when necessary. When performing laparoscopic intragastric submucosal dissection, the laparoscope port position is shown in the figure on the right as a 12-mm trocar (black solid circle) that was inserted intragastrically with a laparoscopic monitor and changed to an intragastric monitor port.
