  • Efficacy of near-infrared fluorescence cholangiography using indocyanine green in laparoscopic cholecystectomy: A retrospective study
    Roy Patankar, RK Mishra, Vivek Bindal, CP Kothari, Prashant Rahate, et al.
    Journal of Minimal Access Surgery, 2023
    Context: While laparoscopy has been the standard procedure for gallstone treatment, recent advances including the use of indocyanine green (ICG) in laparoscopic cholecystectomy have made it easier to understand the biliary tree and reduce the risk of bile duct injury. Aims: In this retrospective study, we aim to determine the efficacy of ICG in near-infrared fluorescence cholangiography (NIRFC) for visualising biliary anatomy. Settings and Design: A total of 90 patients with the symptoms of cholelithiasis were enrolled for this retrospective study. Subjects and Methods: All the patients underwent cholecystectomy approximately 53.8 min (40–90 min) after the intravenous administration of mean volume 1.6 ml (1–2 ml) ICG. The surgeons used NIRFC along with ICG for real-time visualisation of biliary anatomy. Results: The mean operative time for the surgery was 65.7 min (25-120 min) with no post-surgical complications observed in the patients. The average length of stay was 2 days (1–3 days). ICG usage with NIRFC enabled identification of cystic duct, common hepatic and common bile duct, the junction between common hepatic and bile duct, right and left hepatic duct in 87.7%, 94.4%, 80% and 14.4% of cases, respectively. Conclusions: ICG fluorescence allowed successful visualisation of at least 1 biliary structure in 100% of cases.
  • Intestinal duplication in an elderly-male presented as sigmoid volvulus
    Veeranadha Reddy, Naveen Eemaraka, Yendluri Jerusha Jasmine, Samir Ranjan Nayak
    Formosan Journal of Surgery, 2021
    Alimentary tract duplications are uncommon congenital anomalies that are often detected in the first decade of life. However, a smaller number of cases may remain unsuspected until adulthood. These anomalies are most common in the ileum and usually present at the bowel's mesenteric border. These can also occur anywhere in the digestive tract. This article reports a case of a 74-year-old male with intestinal duplication arising from the antimesenteric border of the transverse colon, who clinically presented as sigmoid volvulus.
  • Virtual Operating Room Simulation Setup (VORSS) for Procedural Training in Minimally Invasive Surgery – a Pilot Study
    Sandeep Ganni, Meng Li, Sanne M. B. I. Botden, Samir Ranjan Nayak, Bhaskar Rao Ganni, et al.
    Indian Journal of Surgery, 2020
    Virtual reality (VR) training is widely used in several minimal invasive surgery (MIS) training curricula for procedural training. However, VR training in its current state lack immersive training environments, such as using head-mounted displays that is implemented in military or aviation training and even entertainment. The virtual operating room simulation setup (VORSS) is explored in this study to determine the effectiveness of immersive training in MIS. Twenty-eight surgeons and surgical trainees performed a laparoscopic cholecystectomy on the VORSS comprising of a head-mounted 360-degree realistic OR surrounding on a VR laparoscopic simulator. The VORSS replicated a full setup of instruments and surgical team-members as well as some of the distractions occurring during surgical procedures. Questionnaires were followed by semi-structured interviews to collect the data. Experts and novices found the VORSS to be intuitive and easy to use (p = 0.001). The outcome of the usability test, applying QUESI and NASA-TLX, reflected the usability of the VORSS (p < 0.05), at the cognitive level, which indicates a good sense of immersion and satisfaction, when performing the procedure within VORSS. The need for personalized experience within the setup was strongly noted from most of the participants. The VORSS for procedural training has the potential to become a useful tool to provide immersive training in MIS surgery. Further optimizing of the VORSS realism and introduction of distractors in the OR should result in an improvement of the system.
  • Laparoscopic gonedectomy in a case of complete androgen insensitivity syndrome
    Y Himabindu, G Bhaskararao, SamirRanjan Nayak, M Sriharibabu
    Journal of Human Reproductive Sciences, 2014
    Complete Androgen insensitivity syndrome is a disorder of hormone resistance characterized by a female phenotype in an individual with an XY karyotype. The pathogenesis of CAIS involves a defective androgen receptor gene located on X-chromosome at Xq11-12and end organ insensitivity to androgens, although androgen concentrations are appropriate for the age of the patient. There are three major types of androgen insensitivity syndrome: Complete androgen insensitivity syndrome, minimal androgen insensitivity syndrome, and partial androgen insensitivity syndrome. Management of androgen insensitivity syndrome includes multidisciplinary approach and involves gonedectomy to avoid gonadal tumors in later life. Hormone replacement therapy (HRT) and psychological support are required in long-term basis.
