Introduction: Robotic-assisted total knee arthroplasty (RA-TKA) is associated with a higher carbon footprint compared with manual TKA. This review sought to reduce the carbon and financial costs associated with MAKO RA-TKA by 'leaning' surgical trays.

Methods: Surgeons routinely performing MAKO RA-TKA were consulted, and a consensus was reached on items from the standard knee instrument trays that were redundant and could be removed. Two new 'lean trays' were then introduced for MAKO RA-TKA. Carbon and financial savings were calculated based on the reduction in the number of trays requiring decontamination, sterilisation and repackaging.

Results: Implementing lean methodology has reduced the tray count by one, by removing 36 out of 152 instruments per case. In five months, the use of lean trays resulted in saving 115 trays being opened, reprocessed and sterilised. This project has resulted in numerous benefits, including a total carbon saving of 220.85kgCO2e (carbon dioxide equivalent) due to reduced use of sterilisation processes (176kgCO2e) and tray wraps (44.85kgCO2). Staff feedback was positive, noting the ability to count instruments more quickly, increased space in theatre and reduced learning curve for new staff. Additionally, there was a financial saving of approximately £5,750 due to reduced burden on sterilisation services.

Conclusions: It is imperative that innovative technologies are implemented with sustainability in mind and that any potential environmental harm is mitigated wherever possible. In this regard, the implementation of 'lean' surgical instrument trays should be considered to minimise the environmental impact of surgery while also improving efficiency and lowering costs.

We present a case of previously unclassified duplicated gallbladder which posed a surgical challenge intraoperatively by mimicking a choledochal cyst. An intraoperative cholangiogram was performed followed by a simple cholecystectomy. No further dissection was performed to avoid bile duct injury and complication from the unconventional anatomy. Postoperative imaging and histology, followed by the second operation confirmed findings consistent with the duplicated gallbladder. Through this case, we have demonstrated the principles of safe cholecystectomy and the importance of a staged approach in an unanticipated encounter of anatomical uncertainty, as well as the description of a new variant of duplicated gallbladder.

Introduction: Return to theatre for arrest of post-tonsillectomy haemorrhage represents a significant complication of a commonly performed Ear, Nose and Throat procedure. We used Hospital Episode Statistics data to quantify this risk. This method has been used previously for data from 2002-2004 and again for 2010-2016. In this article, coblation tonsillectomy was considered separately as it had not been analysed in previous studies.

Methods: We used Hospital Episode Statistics data provided by the Department of Health to determine the risk of return to theatre for patients undergoing tonsillectomy between 2016 and 2022. Adults and children were analysed separately.

Results: Between 1 April 2016 and 30 April 2022, 179,172 tonsillectomies were performed (not including coblation tonsillectomy), 4,311 (2.41%) of which returned to theatre for control of postoperative bleeding. In children, 1.16% returned to theatre, whereas in adults, 3.80% returned (p<0.05). When including coblation tonsillectomy, the return to theatre rate was 0.82% in children, 3.46% in adults and 1.92% overall.

Conclusions: This study shows that adults remain more than three times more likely than children to require a return to theatre for arrest of haemorrhage following tonsillectomy. The rates of post-tonsillectomy haemorrhage decrease when coblation tonsillectomies are added to the analysis. The rate of return to theatre for post-tonsillectomy haemorrhage seems to have stabilised compared with previous work carried out. The authors recommend further work to assess the complication rate of tonsillectomy in the UK and to compare coblation tonsillectomy with other techniques.

Introduction: Owing to limited outpatient support for drain management, delayed discharge after mastectomy is more prevalent in developing countries. Utilising half-vacuum (HV) suction drains for routine drainage after mastectomy could lead to a reduced incidence of seroma and a shorter hospital stay. This systematic review and meta-analysis compared the outcomes of HV against full-vacuum (FV) suction drains in patients who underwent modified radical mastectomy for breast cancer.

Methods: Differences between the two groups in length of hospital stay, total volume of drain effluent and incidence of seroma were assessed. RevMan 5.4 was used to calculate the odds ratio (OR) and relative risk (RR) for dichotomous data, and the mean difference (MD) for continuous data.

Results: Nine randomised controlled trials were included in this review. Using HV drains reduced both the mean length of hospital stay (MD: -2.30 days, 95% confidence interval [CI]: -4.10 to -0.49 days, I²=97%) and the mean total volume of effluent (MD: -132.61ml, 95% CI: -207.32ml to -57.91ml, I²=88%) compared with FV drains. However, there was no statistically significant difference in incidence of seroma between the two groups (RR: 0.67, 95% CI: 0.30 to 1.46, I²=65%). Likewise, there was no difference in rate of seroma occurrence on sensitivity analysis (OR: 1.29, 95% CI: 0.72 to 2.33, I²=74%).

Conclusions: There was no difference in the incidence of seroma between HV and FV suction drainage. Conversely, a reduction in the length of hospital stay and the total volume of drain effluent was observed for mastectomy patients with a HV drain.

Introduction: The aim of this study was to explore whether there were any differences in consultant colorectal surgeon training and adjusted 90-day postoperative colorectal cancer mortality rates (AMR).

Methods: We undertook a retrospective analysis of outcomes data published on the Association of Coloproctology of Great Britain and Ireland (ACPGBI) website. A total of 51,562 procedures for patients in England diagnosed with large bowel cancer between 2010 and 2015, registered under 551 consultants were included. Consultants were split into two cohorts. The first group were the pre-Calman Trained Consultants (pre-CTr), who completed their training before 1998. The second group-the post-Calman Trained Consultants (post-CTr)-included those who received their Certificate of Completion of Training (CCT) under the Calman Training Principles (CTC, 1998-2007) and the Modernising Medical Careers Curriculum (MMC, 2008 and onwards). The outcome measure was an AMR.

Results: The pre-CTr cohort (n=84) consisted of 3.6% female colorectal consultants (n=3/84), whereas the post-CTr cohort (n=467) consisted of 14.3% female colorectal consultants (n=67/467) (p=0.006). In this cross-sectional analysis over 5 years, the average pre-CTr undertook a greater number of colorectal resections than their post-CTr peers: median procedures (interquartile range, IQR): 104 (59) vs 89 (57) respectively, p=0.008. The median AMR was significantly greater among pre-CTrs compared with post-CTrs, median AMR (IQR): 2.7% (2.0) vs 2.1% (2.9), p=0.022.

Conclusions: These data indicate that the implementation of the MMC and Calman training principles for colorectal training is associated with a statistically lower AMR compared with other historical training periods. This merits further exploration.

Introduction: A multidisciplinary team (MDT) approach to polytrauma patients minimises morbidity and mortality. This project assesses the extent to which British Orthopaedic Association Standards for Trauma guidelines for the management of the frail Orthopaedic patient are currently being met.

Methods: A retrospective analysis was performed of all Trauma and Orthopaedic patients in multiple medical institutions over a 2-week capture period from 1 March 2022 until 14 March 2022 inclusive. Data collected included age, sex, injury, length of stay and dates of speciality input.

Results: A total of 1,050 patients were included from 27 hospitals. The median age was 80 years, with 560 (53.3%) of all fractures being neck of femur fractures. Of the 1,050 patients, 870 (82.9%) were managed operatively. The median number of different speciality involvements was 3; 645 (61.4%) had an orthogeriatric (OG) review. In major trauma centres (MTC), 93.3% had OG input, compared with 66.3% in non-MTC. The speciality with the greatest input was Radiology, with Plastics having the lowest input.

Conclusion: A standardised MDT approach is needed to optimise care and recovery in orthopaedic trauma patients. The difference in results regarding speciality involvement is substantial and needs to be addressed to minimise disparities in care received by this vulnerable cohort of patients.

Introduction: Up to 30% of patients with colorectal cancer present as an emergency and have worse outcomes than elective patients. Compared with left-sided cancers, malignancies arising in the right colon are significantly under-researched. We sought to compare cancer care quality and clinical outcomes between emergency and elective presentations of right-sided colon cancer (RCC).

Methods: This multicentre, retrospective study included all patients who underwent operative management for a RCC, from 1 April 2017 to 31 March 2022. Data were collected from electronic patient records, and host and tumour factors as well as outcomes between emergency and elective cohorts were compared.

Results: Overall, 806 patients (median age 72 years) were included. Some 175 patients (22%) presented as an emergency: 140 in obstruction and 35 with tumour perforation, compared with 1 patient with tumour perforation in the elective group (p < 0.001). The emergency group had higher rates of postoperative complications (59.1% vs 20.0%, p < 0.001), increased 90-day mortality (13.7% vs 1.3%, p < 0.001) and a longer hospital stay (5 vs 10 days, p < 0.001). From the emergency cohort only 29.2% of eligible patients received adjuvant chemotherapy and in multivariate regression analysis emergency presentation was associated with a decreased likelihood of receiving adjuvant chemotherapy (odds ratio 0.26 [0.14-0.47], p < 0.001).

Conclusions: Both short- and long-term outcomes after emergency presentation of RCC are poor, with inadequate access to subsequent chemotherapy. Strategies addressing emergency presentations of left-sided tumours have moved towards temporisation and elective surgery. Delaying major resectional surgery for optimisation may improve outcomes and access to adjuvant therapies for RCC.

Introduction: The number of bariatric operations is increasing each year. Sleeve gastrectomy is the most popular procedure; however, it often requires revision surgery because of insufficient weight loss, weight regain or gastro-oesophageal reflux disease (GORD). The most popular revisional procedures are Roux-en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB). The primary outcome of this meta-analysis was weight loss after revisional surgery following laparoscopic sleeve gastrectomy and the secondary outcomes were gastro-oesophageal reflux, BMI difference, operative time, bleeding and anastomotic leak.

Methods: A systematic electronic search was undertaken using PubMed, MEDLINE, Ovid, Cochrane Library and Google Scholar following PRISMA guidelines. The initial search identified 2,546 articles. After screening, seven papers met the inclusion criteria: six retrospective studies and one randomised controlled trial.

Results: In total, 802 patients met the inclusion criteria: 390 had an OAGB and a further 412 had an RYBG. All patients previously had a sleeve gastrectomy for weight loss. The length of follow-up was 12 months for our primary outcome. We found no statistically significant difference in excess weight loss (%EWL) between OAGB and RYGB (p = 0.11). The incidence of postoperative reflux was statistically significantly higher in the OAGB group (16% vs 10.1%, p < 0.003). Operative time was statistically significantly lower in the OAGB group (p = 0.04).

Conclusions: This meta-analysis showed no statistically significant difference between the two revision bariatric surgery procedures for %EWL. RYGB was superior to OAGB in reducing the incidence of symptomatic GORD, whereas OAGB had a significant shorter operative time.
