Does virtual reality in the preoperative setting for colorectal cancer surgery improve patient understanding? A randomized pilot study.

BACKGROUND: Virtual reality (VR) enhanced radiology could help improve communication with colorectal cancer patients and therefore increase understanding in the perioperative setting. The objective of this pilot trial is to assess the feasibility of conducting a randomized control trial in terms of recruitment, use and acceptability of the VR technology and validity of data collection methods. METHODS: A prospective, single-centre randomized control trial was conducted at St John of God Midland Hospital in Western Australia from November to December 2021. After standard informed consent with their surgeon, elective patients planned for resection of colorectal cancer were randomized to either 'standard consent' (shown computed tomography (CT) images only) or 'VR consent' (shown CT images and immersive VR models). RESULTS: Nine patients were recruited (four control; five intervention). There was a trend towards improved patient reported understanding without reaching statistical significance. Most patients preferred the use of VR as compared to CT as an educational tool during the consent process (P = 0.03). There were no adverse effects. CONCLUSION: VR was well tolerated and patients enjoyed using the technology. Its use in an outpatient clinic setting for elective colorectal cancer surgery is feasible. Improvement in patient understanding using VR compared to standard consent processes in colorectal surgery should be tested in a statistically powered, high quality study design.

Bryant's sign as a manifestation of a retroperitoneal paraduodenal bleed and subsequent small bowel obstruction.

Bryant's sign is defined as ecchymosis at the base of the penis and scrotum and is usually associated with a retroperitoneal bleed or ruptured aortic aneurysm. We report the case of a retroperitoneal paraduodenal bleed which presented with Bryant's sign. Imaging confirmed a pancreaticoduodenal arcade microaneurysm and associated low-grade coeliac artery stenosis (Sutton-Kadir syndrome). Retroperitoneal bleeding can be life threatening and requires prompt diagnosis and management. However, diagnosis can be challenging due to the clinical variation in presentation. The rarity of presentation in this case caused significant uncertainty necessitating a multidisciplinary approach for diagnostic clarity and safe patient care.

The impact of sarcopenia on outcomes in patients with inflammatory bowel disease undergoing colorectal surgery.

INTRODUCTION: Sarcopenia is an independent predictor of poor post-operative outcomes following major surgery. Inflammatory bowel disease (IBD) consists of Crohn's disease (CD) and ulcerative colitis (UC), which are chronic inflammatory conditions involving the gastrointestinal system. Evidence demonstrates that up to 60% of patients with IBD have sarcopenia. Despite advances in medical management, more than 15% of patients with UC and 80% with CD eventually require surgical intervention. The primary aim of the study was to assess the impact of sarcopenia on post-operative anastomotic leak rates. METHODS: A retrospective cohort study of patients at Royal Perth Hospital who underwent major abdominal surgery for management of IBD between January 2010 and December 2020 was performed. Sarcopenia was assessed according to the skeletal muscle index at the level of the third lumbar vertebrae using the cut off 52.4 and 38.5 cm2 /m2 for men and women, respectively. RESULTS: A total of 147 patients were included. The prevalence of sarcopenia within the study population was 36.1%. Patients with sarcopenia were significantly taller (P = 0.025) and were more likely to be on pre-operative steroid medications (P = 0.045). There was no difference in the remaining baseline characteristics between sarcopenic and non-sarcopenic patients. Patients with sarcopenia were more likely to develop a post-operative anastomotic leak (OR:11.303, 95% CI, 1.53-83.51, P = 0.017), grade IV complications (OR:6.79, 95%CI:1.1-43.6, P = 0.044) and require total parenteral nutrition (TPN) (OR:3.212, 95% CI:1.3-8.1, P = 0.013). CONCLUSIONS: Sarcopenia significantly increases the risk of major post-operative complications for patients with IBD undergoing colorectal surgery.
