RESUMO
BACKGROUND: Textbook outcome (TO) is an objective, composite measure of clinical outcomes in surgery. TO in liver surgery has been used in previous international studies to define and compare performance across centres. This study aimed to review TO rates following liver resection at a single institution. The secondary aim was to use a CuSum analysis to evaluate monitoring of performance quality over time for colorectal cancer liver metastases (CRCLM). METHODS: All patients undergoing liver resection for benign and malignant causes from Christchurch Hospital hepatobiliary unit between 2005 and 2022 were included. Textbook outcomes measures were the absence of; intraoperative incidents, Clavien-Dindo >3 complication, 90 day re-admission, 90 day mortality, R1 resection, and post-operative bile leak/liver failure. Sequential CuSum analysis was performed to review achievement of TO in liver resections for colorectal cancer liver metastases (CRCLM). RESULTS: Four hundred and seventy-eight patients were included in this study, 54 had resection for benign pathology, 290 for CRCLM and 134 for other malignancies. TO was achieved in 74% of cases overall, with rates for benign, CRCLM and other malignancy being 82%, 73% and 74% respectively (P = 0.405). CuSum analysis documented a deterioration in performance after patient 60, with return to baseline by end of study period. CONCLUSIONS: TO for liver resection in a medium sized centre in New Zealand are comparable to published rates. It is possible to use process control techniques like CuSum with the binary result of TO to monitor performance, providing opportunity for continuous improvement in surgical units.

BACKGROUND: A positive association between volume and outcome for certain operations has led to increasing centralization. The latter is associated with a greater travel burden for patients. This study investigated patient preferences for location of care for cancer surgery. METHODS: Two hundred and one participants were recruited from those who have had recent cancer surgery and from general practice or outpatient clinics in both urban and rural locations in the upper South Island of New Zealand. A questionnaire presented participants with a hypothetical scenario of needing cancer surgery and they were asked to indicate their preference of either a hospital 1 or 5 h away. Scenarios evolved in risk of mortality, complications and need for hospital transfer due to a complication. RESULTS: The majority of participants preferred surgery at the closer hospital when there was a negligible difference in risk. Preference shifted to the distant hospital in a linear relationship as the risk of mortality or complications at the closer hospital increased. Respondents were more likely to prefer the distant hospital from the outset if there was a risk of requiring transfer. CONCLUSION: The majority of participants preferred surgery at the closer hospital if risks were comparable but chose to travel as the risk increased and to avoid hospital transfer due to a complication. New Zealand's unique geography and population make it impossible to replicate centralization models from other countries. The drive for improved outcomes must take equity and patient values into consideration.

BACKGROUND: Data on interventions to reduce postoperative pancreatic fistula (POPF) following pancreatoduodenectomy (PD) are conflicting. The aim of this study was to assimilate data from RCTs. METHODS: MEDLINE and Embase databases were searched systematically for RCTs evaluating interventions to reduce all grades of POPF or clinically relevant (CR) POPF after PD. Meta-analysis was undertaken for interventions investigated in multiple studies. A post hoc analysis of negative RCTs assessed whether these had appropriate statistical power. RESULTS: Among 22 interventions (7512 patients, 55 studies), 12 were assessed by multiple studies, and subjected to meta-analysis. Of these, external pancreatic duct drainage was the only intervention associated with reduced rates of both CR-POPF (odds ratio (OR) 0.40, 95 per cent c.i. 0.20 to 0.80) and all-POPF (OR 0.42, 0.25 to 0.70). Ulinastatin was associated with reduced rates of CR-POPF (OR 0.24, 0.06 to 0.93). Invagination (versus duct-to-mucosa) pancreatojejunostomy was associated with reduced rates of all-POPF (OR 0.60, 0.40 to 0.90). Most negative RCTs were found to be underpowered, with post hoc power calculations indicating that interventions would need to reduce the POPF rate to 1 per cent or less in order to achieve 80 per cent power in 16 of 34 (all-POPF) and 19 of 25 (CR-POPF) studies respectively. CONCLUSION: This meta-analysis supports a role for several interventions to reduce POPF after PD. RCTs in this field were often relatively small and underpowered, especially those evaluating CR-POPF.

BACKGROUND: The complexity of pancreaticoduodenectomy and fear of morbidity, particularly postoperative pancreatic fistula, can be a barrier to surgical trainees gaining operative experience. This meta-analysis sought to compare the postoperative pancreatic fistula rate after pancreatoenteric anastomosis by trainees or established surgeons. METHODS: A systematic review of the literature was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, with differences in postoperative pancreatic fistula rates after pancreatoenteric anastomosis between trainee-led versus consultant/attending surgeons pooled using meta-analysis. Variation in rates of postoperative pancreatic fistula was further explored using risk-adjusted outcomes using published risk scores and cumulative sum control chart analysis in a retrospective cohort. RESULTS: Across 14 cohorts included in the meta-analysis, trainees tended toward a lower but nonsignificant rate of all postoperative pancreatic fistula (odds ratio: 0.77, P = .45) and clinically relevant postoperative pancreatic fistula (odds ratio: 0.69, P = .37). However, there was evidence of case selection, with trainees being less likely to operate on patients with a pancreatic duct width <3 mm (odds ratio: 0.45, P = .05). Similarly, analysis of a retrospective cohort (N = 756 cases) found patients operated by trainees to have significantly lower predicted all postoperative pancreatic fistula (median: 20 vs 26%, P < .001) and clinically relevant postoperative pancreatic fistula (7 vs 9%, P = .020) rates than consultant/attending surgeons, based on preoperative risk scores. After adjusting for this on multivariable analysis, the risks of all postoperative pancreatic fistula (odds ratio: 1.18, P = .604) and clinically relevant postoperative pancreatic fistula (odds ratio: 0.85, P = .693) remained similar after pancreatoenteric anastomosis by trainees or consultant/attending surgeons. CONCLUSION: Pancreatoenteric anastomosis, when performed by trainees, is associated with acceptable outcomes. There is evidence of case selection among patients undergoing surgery by trainees; hence, risk adjustment provides a critical tool for the objective evaluation of performance.

BACKGROUND: Multiple risk scores claim to predict the probability of postoperative pancreatic fistula (POPF) after pancreatoduodenectomy. It is unclear which scores have undergone external validation and are the most accurate. The aim of this study was to identify risk scores for POPF, and assess the clinical validity of these scores. METHODS: Areas under receiving operator characteristic curve (AUROCs) were extracted from studies that performed external validation of POPF risk scores. These were pooled for each risk score, using intercept-only random-effects meta-regression models. RESULTS: Systematic review identified 34 risk scores, of which six had been subjected to external validation, and so included in the meta-analysis, (Tokyo (N=2 validation studies), Birmingham (N=5), FRS (N=19), a-FRS (N=12), m-FRS (N=3) and ua-FRS (N=3) scores). Overall predictive accuracies were similar for all six scores, with pooled AUROCs of 0.61, 0.70, 0.71, 0.70, 0.70 and 0.72, respectively. Considerably heterogeneity was observed, with I2 statistics ranging from 52.1-88.6%. CONCLUSION: Most risk scores lack external validation; where this was performed, risk scores were found to have limited predictive accuracy. . Consensus is needed for which score to use in clinical practice. Due to the limited predictive accuracy, future studies to derive a more accurate risk score are warranted.

BACKGROUND: Textbook Outcome (TO) is a novel composite measure of clinical outcomes that can be used to measure the quality of surgical outcomes. TOs for pancreatic surgery were published by the Dutch Pancreatic Cancer Group (DPCG) in 2020. The aim of this study was to explore how a medium volume hepatopancreaticobiliary unit could use TO to benchmark local outcomes following pancreatic surgery. METHODS: Retrospective analysis of prospectively collected data from patients who underwent pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) for all indications between March 2005 and February 2020 at Christchurch Hospital (CH). Analysis of TO items as defined by the DPCG was performed and compared to nationwide Dutch outcomes (2014-2017), including cumulative analysis using CuSum. RESULTS: In total, 273 patients were included (median age 63 years; 51% female) of which 182 (67%) underwent PD and 91 (33%) underwent DP (median annual volume 12 PDs/6 DPs). Overall, 58% of patients undergoing PD and 74% of patients undergoing DP achieved TO, compared with 58% and 67%, P = 0.944 and P = 0.231, respectively, for the Netherlands (median annual volume 33 PDs/8 DPs per hospital). CONCLUSIONS: TO offers a useful quality measure to benchmark local outcomes following pancreatic surgery against an external nationwide analysis. The results show that as a medium volume centre performance was comparable to previously published Dutch results, which included high volume centres. Applying CuSum methodology to the TO metric allows a continuous measure of performance. This offers the potential to provide feedback for quality improvement strategies.

BACKGROUND: Internationally pancreatic surgery has become increasingly centralized; however, geographical and population distribution within New Zealand (NZ) limits the practicalities of such an approach. The aim of this study was to review the short-term outcomes of patients undergoing pancreatic surgery by a single hepato-pancreato-biliary trained surgeon in a centre that would meet the minimum criteria set by the NZ National Standards but not necessarily the definition of a high-volume surgeon/centre. METHODS: A retrospective review of consecutive patients undergoing pancreatic resection within an enhanced recovery programme by a single surgeon between March 2005 and April 2013. Primary outcomes were 30-day morbidity and 90-day mortality. RESULTS: A total of 156 patients who underwent a pancreatic resection were included. Eighty-two (53%) patients underwent a pancreaticoduodenectomy. Forty-seven (30%) underwent a left pancreatectomy. Overall, 30-day morbidity was 64% and overall 90-day mortality was 2.6%. Overall median length of stay was 11 (3-140) days. CONCLUSIONS: Acceptable outcomes have been achieved for patients undergoing pancreatic resection within a centre that meets the criteria proposed by the NZ National Standards for treatment of pancreatic cancer.

BACKGROUND AND AIM: Extra-pancreatic infectious complications in acute pancreatitis increase morbidity, but their incidence and association with infected pancreatic necrosis is unknown. Half of bacterial cultures of pancreatic necrosis are of non-enteric origin, raising the possibility of other sources of infection. The aim of this systematic review was to assess the incidence of extra-pancreatic infectious complications in acute pancreatitis, their timing, and relation to severity of pancreatitis and mortality. METHODS: A systematic review was performed using Ovid MEDLINE, Embase and Cochrane Libraries, following PRISMA guidelines. Search terms were "Pancreatitis" AND "Infection" AND ("Complication" OR "Outcome"). RESULTS: 19 studies with 1741 patients were included. Extra-pancreatic infectious complication incidence was 32% (95% CI 23-41%), with the commonest being respiratory infection (9.2%) and bacteraemia (8.4%). Extra-pancreatic infectious complications were not associated with the predicted severity or the mortality of acute pancreatitis. Only 3 studies reported a relation of timing between extra-pancreatic and pancreatic infectious complications. CONCLUSIONS: This is the first systematic review to evaluate the incidence of extra-pancreatic infectious complications in acute pancreatitis, which a third of patients with acute pancreatitis will develop. Implications are vigilance and prompt treatment of extra-pancreatic infection, to reduce possibility of progression to infected pancreatic necrosis.

BACKGROUND: Although cutaneous melanoma (CM) is rare among dark-skinned populations, it has been found that dark-skinned patients diagnosed with CM tend to have greater Breslow thickness and therefore a worse prognosis. METHODS: Data was obtained from the New Zealand Cancer Registry pertaining to CM ICD-10 codes from 2000 to 2004. This data was used to compare different ethnicities. We compared New Zealand Europeans with those identifying themselves as Maori. Incorrect or absent data, benign nevi, and melanoma in situ were all excluded from analysis. Only one data entry was accepted per patient to avoid the inclusion of metastases. RESULTS: Overall, 9004 patients were registered as being diagnosed with CM during 2000-2004, and 7120 with complete ethnicity data were analyzed. A total of 69 cases were identified as Maori. The incidence of CM among Maori is 2.7 per 100,000. Maori had significantly greater Breslow thickness compared with New Zealand Europeans (1.3 vs. 0.80 mm, P < 0.0001). There were differences in type of CM between the two groups (P < 0.00001); in particular, Maori had more acral CM (2.9% vs. 0.8%). CONCLUSIONS: Cutaneous melanoma is much less common among Maori than among New Zealand Europeans, but Maori have a greater Breslow depth and therefore have a worse prognosis. Increased awareness on behalf of these groups and health care practitioners should assist in ensuring early detection, thereby improving the overall outcome in Maori.

AIM: To ascertain the level of acceptance of the PRIME (Primary Response In Medical Emergencies) scheme by rural general practitioners (GPs) in New Zealand. METHODS: A nationwide, anonymous, postal/email questionnaire was sent to 536 rural/semi-rural GPs, inquiring as to their involvement in and opinions of emergency care, and the acceptability of the PRIME scheme. RESULTS: The overall response rate was 42%. PRIME training courses and PRIME equipment were regarded as excellent. However, concerns were raised by both PRIME and non-PRIME groups regarding the quality of triaging information given during emergencies and levels of remuneration for call-outs (especially medical call-outs). Additional concerns included lack of flexibility with the PRIME contract in some areas. Some GPs were also concerned that their involvement was less about providing a higher skill level in resuscitation than about filling the gaps in the already-stretched rural ambulance services, which was not the intention of the PRIME scheme. CONCLUSIONS: The inclusion of rural GPs in emergency care teams needs to be recognised and adequately remunerated, and these issues should be reflected in the ongoing development of pre-hospital emergency service contracts.
