Background: Healthcare systems globally face the issue of resource constraints and need for prioritization of elective surgery. Inclusive, explicit prioritization tools are important in improving consistency and equity of access to surgery across health systems. The General Surgical Prioritization Tool developed by New Zealand's Ministry of Health scores patients for elective non‐cancer surgery based on surgeon's clinical judgement and patient derived Impact on Life (IoL) scores. This study aims to measure the changes in patient derived IoL scores after common general surgical procedures to enable direct comparison and inform future prioritization. Method: This longitudinal observational study enrolled 322 participants who had undergone elective general surgical procedures. Participants were contacted 3 to 9 months after their procedures and requested to complete the IoL questionnaire. The primary endpoint was the change in IoL scores after surgery among the different procedures. Results: Overall, 229/304 (75%) participants responded to the questionnaire and there were no significant baseline differences between responders and non‐responders. Patients in the gallbladder treatment group had the greatest improvement in IoL scores. Patients across all ethnic groups had similar changes in IoL scores. Multivariate analysis showed that gallbladder surgery (relative to hernia surgery) and pre‐surgery IoL scores significantly predicted improvement. Conclusion: The patient reported IoL score recorded at prioritization for surgery all reduced, albeit to varying amounts, after common general surgical procedures. This, combined with the fact that IoL scores predicted post‐operative improvement support their inclusion in prioritization tools in addition to surgeon derived components. [ABSTRACT FROM AUTHOR]

Background: Sessile serrated lesions (SSL) account for up to 30% of colorectal carcinoma pathogenesis. With multiple classification changes and improvements in colonoscopy equipment and technique, historical reporting may have underestimated the true incidence of SSLs. This study aimed to determine the incidence of SSLs in patients undergoing colonoscopic investigation in Canterbury, New Zealand over a 1‐year period and describe their clinical and pathological characteristics. Methods: Electronic records were searched to identify all lower endoscopy procedures with polypectomy performed from 1 January 2022 to 1 December 2022 (inclusive). Patients' electronic records were used to collect histological classification, location and size of each polyp removed during their procedure. The primary outcome was the number of procedures that had one or more SSL, adenoma or hyperplastic polyp identified. Secondary outcomes included histological classification, location and size of each polyp removed. Results: There were 4346 procedures completed during the study period. Of these, 64.1% (2786) had a polypectomy and 18.6% (808) had at least one SSL excised. Individual polyp analysis was completed on 9166 polyps and found that 24.0% of polyps removed were SSLs and they were found predominately in the right colon (65.1% right colon, 32.6% left colon, 2.3% rectum). SSLs were typically <10 mm (84.8%). Conclusion: This study found a higher incidence of SSLs compared to previous research. These results raise questions regarding whether SLL rates have been historically underestimated, whether SSL detection rate should be included as a key performance indicator and raises further concerns regarding the use of computed tomography colonography as a screening tool.

Background: Watch and wait (W&W) in complete clinical responders after neoadjuvant chemoradiotherapy has increasingly robust data supporting its oncological safety. Recently, studies have assessed the real‐world costs of this strategy compared to surgical resection. Our aim was to compare our oncological safety and costs associated with operative and surveillance strategies to international literature. Methods: Data were retrospectively collected and analysed via electronic health records from March 2014 to March 2021 in Christchurch, New Zealand. Two cohorts were created based on intention to treat. All hospital events were recorded and costed, as well as oncologic outcomes. Our primary endpoints were the cumulative cost of both strategies, 3‐year survival rate, and disease‐free survival. Results: Forty‐eight patients were identified who had rectal cancers resected (OT) with a yPT0N0 pathology, and 42 who were on the wait‐and‐watch (W&W) audit after having a clinical complete response. After exclusions, we identified 38 OT and 23 W&W patients; the W&W group were more co‐morbid (P = 0.05), had worse functional status (P = 0.008), higher BMI (P = 0.34) and more favourable clinical tumour staging (P = 0.01). The operative treatment (OT) group (n = 38) had more acute admissions (34% versus 13% in W&W, P = 0.08, OR 0.29). There was a 35.7% (n = 8 of 23) local recurrence in W&W and none in the OT group (P ≤ 0.001), with successful salvage in the W&W with local recurrence in 71.5% (n = 5 of 7). Three‐year distant metastasis‐free rate was 97.3% in the OT group and 90.9% in W&W (p = 0.05). Overall survival was 100% (W&W) and 94.7% (OT); (P = 0.019). Care in the OT group cost more than W&W, accounting for local regrowth management; $NZ70,759.56 versus $NZ47,905.52 (P = 0.014). Conclusion: This study found better oncological outcomes in the OT group, whilst the W&W group had reduced morbidity and acute bed days. The cost of wait and watch was approximately two‐thirds that of operative treatment, even accounting for salvage procedures for local regrowth. [ABSTRACT FROM AUTHOR]

Introduction: Anastomotic leak (AL) after colon cancer resection is feared by surgeons because of its associated morbidity and mortality. Considerable research has been directed at predictive factors for AL, but not the anatomic type of colonic resection. Anecdotally, certain types of resection are associated with higher leak rates although there remains a paucity of data on this. This study aimed to determine the AL rate for different types of colon cancer resection to inform decisions regarding the choice of operation. Methodology: Retrospective analysis of Bowel Cancer Outcome Registry (BCOR) for all colonic cancer resections with anastomosis between January 2007 and December 2020. Demographic, patient, tumour and outcome data were analysed. AL rates were compared among the different colonic procedures with both univariate and multivariate analysis. Results: 20 191 patients who underwent resection with anastomosis for cancer were included in this study. Of these 535 (2.6%) suffered ALs. While the univariate analysis found male sex, procedure type, symptomatic cancers, emergency surgery, unsupervised registrars, conversion to open surgery, medical complications and higher TNM staging were associated with AL, multivariate analysis, found only procedure type remained a significant predictor of AL (total colectomy (OR 4.049, P<0.001), subtotal colectomy (OR 2.477, P<0.001) and extended right hemicolectomy (OR 2.171, P < 0.001)). Conclusion: AL is more common in extended colonic resections. With growing evidence of similar oncological outcomes between subtotal colectomy and left hemicolectomy for splenic flexure cancers, more limited resections should be considered. The type of colonic resection should be integrated into prediction tools for AL. [ABSTRACT FROM AUTHOR]

Objective: To identify factors associated with death secondary to haemorrhage following major trauma. Methods: A retrospective case–control study was conducted on data from adult major trauma patients attending Christchurch Hospital ED between 1 June 2016 and 1 June 2020. Cases (those who died due to haemorrhage or multiple organ failure [MOF]), were matched to controls (those who survived) in a 1:5 ratio from the Canterbury District Health Board major trauma database. A multivariate analysis was used to identify potential risk factors for death due to haemorrhage. Results: One thousand, five hundred and forty major trauma patients were admitted to Christchurch Hospital or died in ED during the study period. Of them, 140 (9.1%) died from any cause, most attributed to a central nervous system cause of death; 19 (1.2%) died from haemorrhage or MOF. After controlling for age and injury severity, having a lower temperature on arrival in ED was a significant modifiable risk factor for death. Additionally, intubation prior to hospital, increased base deficit, lower initial haemoglobin and lower Glasgow Coma Scale were risk factors associated with death. Conclusions: The present study reaffirms previous literature that lower body temperature on presentation to hospital is a significant potentially modifiable variable in predicting death following major trauma. Further studies should investigate whether all pre‐hospital services have key performance indicators (KPIs) for temperature management, and causes for failure to reach these. Our findings should promote development and tracking of such KPIs where they do not already exist. [ABSTRACT FROM AUTHOR]
