“…If the prone or decubitus position was the best position for localization and measurement, then we also reported the location and distances in the supine position, which is the patient's position during surgery. We examined the entire mucosal surface of the stomach for evidence of other lesions and constructed arterial road maps for the last 4 patients [11]. Finally, we looked for evidence of tumour spread beyond the stomach and for metastases.…”

“…Skeletonizing and managing vessels are crucial for thorough lymphadenectomy during gastrectomy since lymph nodes are located along the vessels (2). Thus, anatomical information of organs and vessels and their variations around the stomach is essential for safe and complete lymphadenectomy during radical gastrectomy (3)(4)(5)(6).…”

IntroductionAbdominal computed tomography (CT) can accurately demonstrate organs and vascular structures around the stomach, and its potential role for image guidance is becoming increasingly established. However, solely using two-dimensional CT images to identify critical anatomical structures is undeniably challenging and not surgeon-friendly. To validate the feasibility of a patient-specific 3-D surgical navigation system for preoperative planning and intraoperative guidance during robotic gastric cancer surgery.Materials and methodsA prospective single-arm open-label observational study was conducted. Thirty participants underwent robotic distal gastrectomy for gastric cancer using a virtual surgical navigation system that provides patient-specific 3-D anatomical information with a pneumoperitoneum model using preoperative CT-angiography. Turnaround time and the accuracy of detecting vascular anatomy with its variations were measured, and perioperative outcomes were compared with a control group after propensity-score matching during the same study period.ResultsAmong 36 registered patients, 6 were excluded from the study. Patient-specific 3-D anatomy reconstruction was successfully implemented without any problems in all 30 patients using preoperative CT. All vessels encountered during gastric cancer surgery were successfully reconstructed, and all vascular origins and variations were identical to operative findings. The operative data and short-term outcomes between the experimental and control group were comparable. The experimental group showed shorter anesthesia time (218.6 min vs. 230.3 min; P=0.299), operative time (177.1 min vs. 193.9 min; P=0.137), and console time (129.3 min vs. 147.4 min; P=0.101) than the control group, although the differences were not statistically significant.ConclusionsPatient-specific 3-D surgical navigation system for robotic gastrectomy for gastric cancer is clinically feasible and applicable with an acceptable turnaround time. This system enables patient-specific preoperative planning and intraoperative navigation by visualizing all the anatomy required for gastrectomy in 3-D models without any error.Clinical trial registrationClinicaltrials.gov, identifier NCT05039333.

“…The bifurcation of the LGA was classified into four types [11]; and that of RGA was classified into five types [1]. According to several studies [6], [7], [8], [10], three-dimensional computed tomographic angiography (CTA) can reveal the bifurcation of the gastric vessels before laparoscopic gastrectomy.…”

Laparoscopic surgery has been widely performed for early gastric cancer. However, laparoscopic surgery has some disadvantages from the limited view of the operative field. Moreover, the topological patterns of vessels in the stomach are complex and varies between patients. Therefore, it is difficult to ligate the gastric arteries and veins in laparoscopic gastrectomy. In this study, we proposed a vessel navigator to guide an optimal path to the target vessels. The proposed method used a topological vessel map obtained from the abdomen computed tomography angiography images. In addition, it was designed to guide the optimal route to the target vessels from the present point. For this purpose, we defined a penalty function to measure how difficult a suggested pathway is compared with the other one. To assess the feasibility of the proposed vessel navigator, we applied to several steps of the laparoscopic gastrectomy.
