RESUMEN
Background Virtual education is an evolving method for teaching medical learners. During the coronavirus disease 2019 pandemic, remote learning has provided a replacement for conferences, lectures, and meetings, but has not been described as a method for conducting a cadaver dissection. We aim to demonstrate how learners perceive a virtual cadaver dissection as an alternative to live dissection. Methods A virtual cadaver dissection was performed to demonstrate several upper extremity nerve procedures. These procedures were livestreamed as part of an educational event with multimedia and interactive audience questions. Participants were queried both during and after the session regarding their perceptions of this teaching modality. Results Attendance of a virtual dissection held for three plastic surgery training institutions began at 100 and finished with 70 participants. Intrasession response rates from the audience varied between 68 and 75%, of which 75% strongly agreed that they were satisfied with the virtual environment. The audience strongly agreed or agreed that the addition of multimedia captions (88%), magnified video loupe views (82%), and split-screen multicast view (64%) was beneficial. Postsession response rate was 27%, and generally reflected a positive perspective about the content of the session. Conclusions Virtual cadaver dissection is an effective modality for teaching surgical procedures and can be enhanced through technologies such as video loupes and multiple camera perspectives. The audience viewed the virtual cadaver dissection as a beneficial adjunct to surgical education. This format may also make in-person cadaver courses more effective by improving visualization and allowing for anatomic references to be displayed synchronously.
RESUMEN
Visceral artery revascularisation through a retroperitoneal approach provides an infrequent yet viable, alternative means of managing mesenteric ischaemia in patients with previous abdominal operations. We present a unique case implementing this surgical approach in a 55-year-old man in which we performed a retroperitoneal aortobifemoral bypass with concomitant retrograde jump graft from the aortic prosthesis to the superior mesenteric artery (SMA) for bilateral lower extremity rest pain and chronic mesenteric ischaemia. Three months previously, the patient had presented with acute mesenteric ischaemia and colonic perforation. He underwent emergent celiac artery stenting followed by an exploratory laparotomy with total abdominal colectomy and diverting loop ileostomy. Given the patient's hostile abdomen, a retroperitoneal approach to SMA revascularisation was elected over a transabdominal approach during concomitant lower extremity revascularisation for critical limb ischaemia. We achieved an excellent technical result with resolution of limb ischaemia and abdominal symptoms.

Strangulated gastric prolapse through a percutaneous endoscopic gastrostomy tract is a rare and potentially life-threatening complication that requires surgical intervention. We describe a case of a 74-year-old woman who was debilitated and ventilator-dependent and who presented with acute gastric prolapse with resultant ischaemic necrosis. The patient underwent an emergent exploratory laparotomy, partial gastrectomy, repair of gastrostomy defect and placement of a gastrojejunostomy feeding tube remote to the previous location. Literature on gastric prolapse in adult patients is sparse, and therefore treatment is not standardised. In this patient with strangulated tissue, the principles of management included the assessment of gastric mucosa viability, resection of ischaemic tissue and closure of the gastrostomy defect.
