Veno-Venous Surgical Bypass for Central Vein Occlusion in a Child: The First in the Literature.

Introduction: During the past two decades, the incidence of chronic kidney disease (CKD) in children worldwide has steadily increased and, even in children, native arteriovenous fistula (AVF) remains the access of choice. Nevertheless, maintaining a well functioning fistula is limited by central venous occlusion due to the widespread use of central venous access devices before AVF creation. Report: A 10 year old girl with end stage renal failure dialysing through a left brachiocephalic fistula presented with left upper limb and facial swelling. She had previously exhausted the option of ambulatory peritoneal dialysis for recurrent peritonitis. A central venogram showed occlusion at the left subclavian vein, which was not amenable for angioplasty through either an upper limb or femoral approach. Given the precious fistula with concomitant worsening venous hypertension, an ipsilateral axillary vein to external iliac vein bypass was performed. Subsequently, her venous hypertension was significantly resolved. This report is the first in English literature on this surgical bypass in a child with central venous occlusion. Discussion: Central venous stenosis or occlusion rates are rising due to extensive central venous catheter use in the paediatric population with end stage renal failure. In this report, an ipsilateral axillary vein to external iliac vein bypass was used successfully as a safe temporary option to maintain AVF. Ensuring a high flow fistula pre-operatively and continued antiplatelet post-operatively will allow longer patency of the graft.

Can We Use Peer-Assisted Learning to Teach Basic Surgical Skills?

BACKGROUND: It is reported that medical students do not receive adequate opportunities to learn surgical skill and are at risk of being unable to perform simple surgical procedures safely. The usefulness of peer-assisted learning (PAL) as a tool to assist in delivering surgical skills training is worth exploring. METHODS: This is a randomised single blinded controlled trial. Fourth-year students from the university's Surgical Society were asked to volunteer as peer tutors and those in 3rd-year were asked to undertake surgical skills training. A cohort of 35 students were selected and randomised to receive basic surgical skills training conducted either by faculty members or peers. The students' performance of basic suturing skills was assessed using a checklist, through directly observed procedural skills (DOPS) technique. The assessment was conducted by faculty blinded to the training. Students' perception to surgical skills training was assessed using a questionnaire survey. RESULTS: The suturing and knotting skills of students learned from their peers was comparable to that acquired from faculty. The students' perceived that their peers could conduct surgical skills training similar to their faculty. CONCLUSION: PAL approach for basic surgical skills training is as effective as faculty-led training. PAL has the potential to optimise the delivery of surgical skills training in undergraduate medical education.
