  • Progress in single-incision laparoscopic surgery for gastric cancer

    With the upgrading of minimally invasive surgical concepts and laparoscopic equipment for gastric cancer, single-incision laparoscopic surgery (SILS) had emerged as a new focus of research in gastric cancer surgery. SILS offered advantages such as reduced damage, superior cosmetic outcomes, decreased postoperative pain, and faster recovery as compared with traditional laparoscopic gastrectomy. However, its level of difficulty limited its further promotion and application. Although numerous studies supported the safety and feasibility of SILS, more high-level evidence-based medical research was required to endorse its widespread use. The author reviewed the development history, current status, and prospects of SILS laparoscopic gastric cancer surgery.

  • Early effectiveness of computer navigation system-assisted transiliac-transsacral screws placement for posterior pelvic ring injuries

    Objective To investigate the early effectiveness of transiliac-transsacral screws internal fixation assisted by augmented reality navigation system HoloSight (hereinafter referred to as “computer navigation system”) in the treatment of posterior pelvic ring injuries. MethodsA retrospective analysis was made in the 41 patients with posterior pelvic ring injuries who had been treated surgically with transiliac-transsacral screws between June 2022 and June 2023. The patients were divided into navigation group (18 cases, using computer navigation system to assist screw implantation) and freehand group (23 cases, using C-arm X-ray fluoroscopy to guide screw implantation) according to the different methods of transiliac-transsacral screws placement. There was no significant difference in gender, age, body mass index, causes of injuries, Tile classification of pelvic fracture, days from injury to operation, usage of unlocking closed reduction technique between the two groups (P>0.05). The time of screw implantation, the fluoroscopy times, the guide wire adjustment times of each screw, and the incidence of complications were recorded and compared between the two groups. The position of the transiliac-transsacral screw was scanned by CT within 2 days after operation, and the position of the screw was classified according to Gras standard. ResultsThe operation was successfully completed in both groups. The time of screw implantation, the fluoroscopy times, and the guide wire adjustment times of each screw in the navigation group were significantly less than those in the freehand group (P<0.05). There were 2 cases of incision infection in the freehand group, and the incision healed by first intention after active dressing change; there was no screw-related complication in the navigation group during operation and early period after operation; the difference in incidence of complications between the two groups (8.7% vs. 0) was not significant (P=0.495). According to the Gras standard, the screw position of the navigation group was significantly better than that of the freehand group (P<0.05). ConclusionCompared with the traditional freehand method, the computer navigation system assisted transiliac-transsacral screws internal fixation in the treatment of posterior pelvic ring injuries has advantages of improving the accuracy of screw implantation and reducing radiation damage and the time of screw implantation.

  • Investigation and analysis on psychological pressure of surgeon-in-chief to complete animal remote surgery using home-made Tumai surgical robot in combination with 5G network

    ObjectiveTo understand the psychological pressure when the surgeon-in-chief remotely completes animal surgery using home-made Tumai surgical robot in combination with 5G network (Abbreviated as“remote robotic surgery” ), and investigate and analyze the sources of psychological pressure, and then provide evidence guidance for the training of surgeon in performing remote robotic surgery. MethodsA modified perceptual stress scale was used to conduct a questionnaire survey. The 44 surgeons-in-chief with robot operation qualification from 10 medical units in the Gansu Province recruited by Gansu Provincial People’s Hospital were as observation subject, who participated in the psychological stress validation test of remote robotic surgery, from September 4, 2022 to October 10, 2022. The difference of psychological stress before and after the test was compared. The stressor of surgeon-in-chief was analyzed by Likert scale. The animals in this study were swines. ResultsA total of 132 valid questionnaires were obtained from 44 surgeons-in-chief. The surgical physician’s perceived stress score after the test was statistically higher than before the test [(47.50±9.06) points vs. (38.34±5.55) points, mean difference and its 95% confidence interval=9.61 (7.00, 12.27), t=7.42, P<0.001]. The analysis results of multiple linear regression showed that the number of robotic surgery performed by the surgeon-in-chief in the past had a negative impact on the psychological pressure of the surgeon-in-chief after the test (β=–0.292, P=0.042); At the same time, the subjective perception data of the surgeon-in-chief, such as unstability of signal transmission and unskilled equipment manipulation by the surgeon had positive impacts on the psychological pressure of the surgeon-in-chief after the test (β=1.987, P=0.026; β=3.184, P=0.010), and the tacit understanding between the surgeon-in-chief and the first assistant had a negative impact on the psychological pressure of the surgeon-in-chief after the test (β=–2.185, P=0.047). ConclusionsAccording to the data from this study, remote robotic surgery will increase the psychological pressure of the surgeon-in-chief. Previous experience in robotic surgery can reduce psychological stress after surgery. The main sources of psychological pressure are unstability of signal transmission, unskilled equipment manipulation by the surgeon, and the tacit understanding between the surgeon-in-chief and the first assistant.

  • Noncontact wide-angle viewing system aided scleral buckling surgery for rhegmatogenous retinal detachment

    ObjectiveTo create a new scleral buckling surgery using noncontact wide-angle viewing system and 23-gauge intraocular illumination for the treatment of rhegmatogenous retinal detachment (RRD), and to evaluate its safety and effectiveness. MethodsA scleral buckling surgery using noncontact wide-angle viewing system and 23-gauge intraocular illumination was performed in 6 eyes of 6 patients with RRD, including 2 males and 4 females. The mean age was 51 years old with a range from 23 to 66 years old. Proliferative vitreoretinopathy (PVR) were diagnosed of grade B in all 6 eyes. Duration of retinal detachments until surgery was 5.8 days with a range from 2 to 13 days. The mean preoperative intraocular pressure (IOP) was 12 mmHg with a range from 9 to 15 mmHg (1 mmHg=0.133 kPa). A 23-gauge optic fiber was used to provide an intraocular illumination. Fully examination of the ocular fundus and cryoretinopexy of retinal breaks was performed under a noncontact wide-angle viewing system. Subretinal fluid drainage through the sclerotomy and buckling procedure were performed under the operating microscope. Intravitreal injection of sterile air bubble was performed in 4 eyes. Antibiotic eye drops was applied in all eyes postoperatively, and all the eyes were followed up for at least 6 months. ResultsRetinal reattachment was achieved in all eyes, and the conjunctiva healed well. The best corrected visual acuity (BCVA) increased in all eyes. The mean postoperative IOP was 15 mmHg with a range from 12 to 19 mmHg. No complications were found intra and postoperatively. ConclusionsThis new scleral buckling surgery using noncontact wide-angle viewing system and 23-gauge intraocular illumination for RRD is safe and effective. Advantages such as higher successful rate, less complication, shorter operating time, and less discomfort of patients were showed comparing with the previous scleral buckling surgery using indirect ophthalmoscope.
