EP.TH.1043Outcomes of liver resections by trainee surgeons versus consultant surgeon – a single centre experience

Introduction Liver resection is a most effective treatment for patients with operable primary or secondary cancer deposits. The role of trainee as a lead surgeon versus consultant surgeon performing liver resections and its impact on surgical outcomes had never been reported. Methods and Materials This study was aimed to assess the liver resection outcomes including operative time, acute kidney injury (AKI), bile leak, sepsis, mortality and hospital readmission within 3 months. A total of 320 liver resections from Addenbookes Hospital at Cambridge between 2015 to 2017 were included in this study. All liver resections were performed under supervision of the consultant surgeon who is either scrubbed or unscrubbed in theatre. Trainee surgeons have performed 116 of 320 as lead surgeon and the consultant surgeons performed the remaining 204. Results The mean operative time was 413±129 versus 383±118 (P = 0.41) minutes in trainee surgeons and consultant surgeons respectively. The incidence of postoperative AKI were similar in between the groups (5/116 versus 11/204;P=0.79). Although the bile leak was numerically high in the trainee group, did not reach statistical difference (13/116 versus 12/204;P=0.12); similar results noted in the incidence of sepsis too (3/116 versus 4/204;P=070). Mortality, hospital readmission at 3 months were (1/204 versus 1/116;P=1) and (2/116 versus 4/204;P=1) respectively. No significant difference was observed. Conclusion Liver resections performed by the trainee surgeons under supervision appeared to be safe without increasing the operative time, morbidity, mortality and hospital readmission at 90 days. Further multicentre prospective study with long-term follow up is recommended.

TP8.2.28 Can surgical advanced care practitioners provide a cost effective local anaesthetic minor procedures service? Results from a 5-year retrospective study

Aims Surgical Advanced Clinical Practitioners (SACP) form part of the extended surgical workforce and are drawn from allied health care backgrounds. The primary aim of this study was to determine if there is a financial benefit performing minor surgical procedures on dedicated SACP lists compared to consultant surgeon lists. Methods This was a retrospective cohort study including all patients who had a minor ‘lumps and bumps’ procedure undertaken between April 2014 and August 2019 at Anonymous Hospitals NHS Trust (AHT) under local anaesthetic by the general surgery team. Data such as lesion type, theatre staffing levels and operating time was collected. The cost of the procedure was calculated by operating time multiplied by cost of staff of per minute according to local banding. Results A total of 1399 patients had a lesion excised; the majority were carried out by a doctor n = 907, the rest independently by a SACP. The majority of lesions excised were lipomas and cysts. There was no difference in the median surgical time (20 minutes, IQR 14) taken to operate on each patient by SACPs and doctors. Minor procedures carried out on consultant surgeon lists cost 62.4% (£21.72) more on average than those on SACP lists (£56.55 vs £34.83 median respectively, p < 0.001) due to excess staff for these cases. Conclusion A dedicated and independent SACP ‘lumps and bumps’ list has shown to be a financially beneficial service. Operative times are similar to doctors. These lists free staff for consultant lists, potentially permitting more major cases.

Establishing the Safety of Training in Off-Pump Coronary Artery Bypass Surgery: A Retrospective Comparison of Outcomes between Trainees and a Consultant Surgeon

Background The safety of training in off-pump coronary artery bypass (OPCAB) surgery and the stage at which trainees should be exposed to this technique remain controversial. This single-center retrospective study aimed to compare outcomes of OPCAB surgery in consultant and trainee cases. Methods Between 2014 and 2018, all isolated OPCAB operations performed under the care of a consultant surgeon (G.A.) were analyzed. Cases where a surgeon below consultant grade performed at least 70% of the distal anastomoses were designated as “trainee cases” with the remaining cases designated as “consultant cases.” The baseline characteristics of patients, perioperative data, and short-term outcomes were prospectively collated and analyzed. Results During the study period, 245 OPCAB cases were identified: 142 (58%) consultant and 103 (42%) trainee cases. The trainee cases were performed exclusively by trainees in the final 2 years of the UK National Cardiothoracic Training Program. Both trainee and consultant groups had low mortality with two perioperative deaths occurring in either group. The rates of serious postoperative complications including stroke (n = 1 vs. 2, p = 0.759), resternotomy for bleeding (n = 3 vs. 7, p = 0.431), and mediastinal infection (n = 2 vs. 3, p = 0.926) were low and not significantly different between the two groups. Patients operated on by trainees had a slightly longer hospital stay than those operated on by the consultant surgeon, although this did not reach statistical significance (9.9 vs. 7.9 days). Conclusions These results demonstrate comparable outcomes in OPCAB surgery between a consultant surgeon and trainees. This study supports the conclusion that training surgeons in OPCAB is appropriate for trainees in the final years of cardiac surgery training.

About a uni-cervical unicorn uterus case with vaginal septum

The unicorn uterus is a common uterine malformation after septate uteri, accounting for 30 to 50% of cases. We report a case of unicorn uterus with an associated vaginal septum discovered during the obstetrical examination of a consultant surgeon for hemorrhage, and exploration of the uterus revealed a uterus during a cesarean section. Maternal-fetal rescue for placenta previa. The interest of this case is to show the double embryological mechanism involved, unilateral aplasia of the muller ducts and the lack of resorption explaining this vaginal septum.
