“…There were no significant differences in other indexes (such as hospital stay, preoperative or postoperative serum creatinine (Scr), and postoperative complications) among the three groups (all P>0.05; Table 5). As a new generation of holographic visualization technology, MR can read image information intuitively, stereoscopically, and comprehensively in the most natural way, which helps surgeons shorten the learning cycle before surgery and quickly locate renal tumors during surgery (3). This study shows that MR can effectively increase successful NSS cases, shorten OT, and decrease WIT and EBL compared with traditional CT imaging.…”

“…In our previous study, Li et al demonstrated that the number of conversions from laparoscopic partial nephrectomy (LPN) to laparoscopic radical nephrectomy (LRN) were 2/50 (4%) and 4/50 (8%) for the MR group and the non-MR group, respectively (3). However, in the present study, we found that the number of conversions from LPN to LRN were 15/50 (30%), 13/50 (26%), and 21/50 (42%) for Group A, Group B, and Group C, respectively.…”

“…For ≥ stage T1b or complex renal tumors (RENAL nephrometry score ≥7), NSS should be selected according to the location, shape, and relationship with adjacent regions (2). Mixed reality (MR) is a new generation of visualization technology, which facilitates an immersive interaction between the user, the real scene, and the virtual scene (3). Preoperatively, MR can help formulate accurate operation plans and reduce the difficulty in identifying complex anatomical structures of tumors.…”

Background: Nephron-sparing surgery has been widely applied in the treatment of renal tumors. Previous studies have confirmed the advantages of mixed reality technology in surgery. The study aimed to explore the optimization of mixed reality technology and its application value in nephron-sparing surgery.Methods: In this prospective study of 150 patients with complex renal tumors (RENAL nephrometry score ≥7) who underwent nephron-sparing surgery, patients were randomly divided into Group A (the normal-dose mixed reality group, n=50), Group B (the low-dose mixed reality group, n=50), and Group C (the traditional computed tomography image group, n=50). Group A and Group C received the normaldose computed tomography scan protocol: 120 kVp, 400 mA, and 350 mgI/mL, while Group B received the low-dose computed tomography scan protocol: 80 kVp, automatic tube current modulation, and 320 mgI/mL. All computed tomography data were transmitted to a three-dimensional visualization workstation and underwent modeling and mixed reality imaging. Two senior surgeons evaluated mixed reality quality. Objective indexes and perioperative indexes were calculated and compared.Results: Compared with Group A, the radiation effective dose in Group B was decreased by 39.6%.The subjective scores of mixed reality quality in Group B were significantly higher than those of Group A (Z=−4.186, P<0.001). The inter-observer agreement between the two senior surgeons in mixed reality quality was excellent (K=0.840, P<0.001). The perioperative indexes showed that the mixed reality groups were significantly different from the computed tomography image group (all P<0.017). More cases underwent nephron-sparing surgery in the mixed reality groups than in the computed tomography image group (P<0.0017).Conclusions: Low-dose computed tomography technology can be effectively applied to mixed reality optimization, reducing the effective dose and improving mixed reality quality. Optimized mixed reality can significantly increase the cases of successful nephron-sparing surgery and improve perioperative indexes.

Advances in Minimally Invasive Surgery

Wearable technology is an emerging field that has the potential to revolutionize healthcare. Advances in sensors, augmented reality devices, the internet of things, and artificial intelligence offer clinically relevant and promising functionalities in the field of surgery. Apart from its well-known benefits for the patient, minimally invasive surgery (MIS) is a technically demanding surgical discipline for the surgeon. In this regard, wearable technology has been used in various fields of application in MIS such as the assessment of the surgeon’s ergonomic conditions, interaction with the patient or the quality of surgical performance, as well as in providing tools for surgical planning and assistance during surgery. The aim of this chapter is to provide an overview based on the scientific literature and our experience regarding the use of wearable technology in MIS, both in experimental and clinical settings.

“…MR has been proven to be a practical tool for intraoperative surgical guidance in the operating room[ 11 ]. Previous studies have shown that MR has been gradually applied to neurosurgery, orthopedics, and urology, yielding improvements in perioperative outcomes for patients[ 12 - 14 ]. In hepatectomy for patients with HCC, MR also exhibit great potential in preoperative planning and intraoperative navigation, which makes hepatectomy more accurate and personalized[ 15 ].…”

BACKGROUND As a new digital holographic imaging technology, mixed reality (MR) technology has unique advantages in determining the liver anatomy and location of tumor lesions. With the popularization of 5G communication technology, MR shows great potential in preoperative planning and intraoperative navigation, making hepatectomy more accurate and safer. AIM To evaluate the application value of MR technology in hepatectomy for hepatocellular carcinoma (HCC). METHODS The clinical data of 95 patients who underwent open hepatectomy surgery for HCC between June 2018 and October 2020 at our hospital were analyzed retrospectively. We selected 95 patients with HCC according to the inclusion criteria and exclusion criteria. In 38 patients, hepatectomy was assisted by MR (Group A), and an additional 57 patients underwent traditional hepatectomy without MR (Group B). The perioperative outcomes of the two groups were collected and compared to evaluate the application value of MR in hepatectomy for patients with HCC. RESULTS We summarized the technical process of MR-assisted hepatectomy in the treatment of HCC. Compared to traditional hepatectomy in Group B, MR-assisted hepatectomy in Group A yielded a shorter operation time (202.86 ± 46.02 min vs 229.52 ± 57.13 min, P = 0.003), less volume of bleeding (329.29 ± 97.31 mL vs 398.23 ± 159.61 mL, P = 0.028), and shorter obstructive time of the portal vein (17.71 ± 4.16 min vs 21.58 ± 5.24 min, P = 0.019). Group A had lower alanine aminotransferas and higher albumin values on the third day after the operation (119.74 ± 29.08 U/L vs 135.53 ± 36.68 U/L, P = 0.029 and 33.60 ± 3.21 g/L vs 31.80 ± 3.51 g/L, P = 0.014, respectively). The total postoperative complications and hospitalization days in Group A were significantly less than those in Group B [14 (37.84%) vs 35 (60.34%), P = 0.032 and 12.05 ± 4.04 d vs 13.78 ± 4.13 d, P = 0.049, respectively]. CONCLUSION MR has some application value in three-dimensional visualization of the liver, surgical planning, and intraoperative navigation during hepatectomy, and it significantly improves the perioperative outcomes of hepatectomy for HCC.
