ABSTRACT
BACKGROUND AND PURPOSE: Preoperative inflammatory markers, such as Glasgow prognostic score, modified Glasgow prognostic score and C-reactive protein to albumin ratio, were shown to be associated with prognosis in patients undergoing pancreatectomy for cancer. However, little is known about their predictive role in a Western population. METHODS: The Norwegian National Registry for Gastrointestinal Surgery (NORGAST) was used to capture all pancreatectomies performed within the study period (November 2015-April 2021). The association between the preoperative inflammatory markers and postoperative outcomes was studied. Their impact on survival was examined in patients operated for pancreatic ductal adenocarcinoma. RESULTS: A total of 1554 patients underwent pancreatectomy in this period. Glasgow prognostic score, modified Glasgow prognostic score and C-reactive protein to albumin ratio were associated with severe complications (Accordion grade ≥ III) in the univariable but not in the multivariable analysis. C-reactive protein to albumin ratio, but not Glasgow prognostic score and modified Glasgow prognostic score, was linked to survival following pancreatectomy for ductal adenocarcinoma. In the multivariable model, age, neoadjuvant chemotherapy, ECOG score, C-reactive protein to albumin ratio and total pancreatectomy correlated with survival. Also, preoperative C-reactive protein to albumin ratio was significantly associated with survival after pancreatoduodenectomy. CONCLUSIONS: Preoperative Glasgow prognostic score, modified Glasgow prognostic score and C-reactive protein to albumin ratio have no role in predicting the complications after pancreatectomy. C-reactive protein to albumin ratio is a significant predictor for survival in ductal adenocarcinoma, yet its clinical relevance should be explored in conjunction with the pathology parameters and adjuvant therapy.

BACKGROUND: Preoperative inflammatory markers were shown to be associated with prognosis following surgery for hepato-pancreato-biliary cancer. Yet little evidence exists about their role in patients with colorectal liver metastases (CRLM). This study aimed to examine the association between selected preoperative inflammatory markers and outcomes of liver resection for CRLM. METHODS: Data from the Norwegian National Registry for Gastrointestinal Surgery (NORGAST) was used to capture all liver resections performed in Norway within the study period (November 2015-April 2021). Preoperative inflammatory markers were Glasgow prognostic score (GPS), modified Glasgow prognostic score (mGPS) and C-reactive protein to albumin ratio (CAR). The impact of these on postoperative outcomes, as well as on survival were studied. RESULTS: Liver resections for CRLM were performed in 1442 patients. Preoperative GPS ≥ 1 and mGPS ≥ 1 were present in 170 (11.8%) and 147 (10.2%) patients, respectively. Both were associated with severe complications but became non-significant in the multivariable model. GPS, mGPS, CAR were significant predictors for overall survival in the univariable analysis, but only CAR remained such in the multivariable model. When stratified by the type of surgical approach, CAR was a significant predictor for survival after open but not laparoscopic liver resections. CONCLUSIONS: GPS, mGPS and CAR have no impact on severe complications after liver resection for CRLM. CAR outperforms GPS and mGPS in predicting overall survival in these patients, especially following open resections. The prognostic significance of CAR in CRLM should be tested against other clinical and pathology parameters relevant for prognosis.

The timing of surgical resection of synchronous liver metastases from colorectal cancer has been debated for decades. Several strategies have been proposed, but high-level evidence remains scarce. Simultaneous resection of the primary tumour and liver metastases has been described in numerous retrospective audits and meta-analyses. The potential benefits of simultaneous resections are the eradication of the tumour burden in one procedure, overall shorter procedure time, reduced hospital stay with the likely benefits on quality of life and an expected reduction in the use of health care services compared to staged procedures. However, concerns about accumulating complications and oncological outcomes remain and the optimal selection criteria for whom simultaneous resections are beneficial remains undetermined. Based on the current level of evidence, simultaneous resection should be restricted to patients with a limited liver tumour burden. More high-level evidence studies are needed to evaluate the quality of life, complication burden, oncological outcomes, as well as overall health care implications for simultaneous resections.
ABSTRACT
BACKGROUND: Universal health care (UHC) should ensure equal access to and use of surgery, but few studies have explored variation in UHC systems. The objective was to describe practice of distal pancreatectomy in Norway covered exclusively by an UHC. METHODS: Data on all patients undergoing distal pancreatectomy from the Norwegian Patient Register over a 5-year period. Age- and gender-adjusted population-based resection rates (adj. per million/yr) for distal pancreatectomy were analysed across 4 regions and outcomes related to splenic salvage rate, hospital stay, reoperation, readmissions and 90-day mortality risk between regions. Risk is reported as odds ratio (OR) with 95% confidence interval (c.i.). RESULTS: Regional difference exist in terms of absolute numbers, with the majority of procedures done in one region (n = 331; 59.7%). Regional variation persisted for age- and gender-adjusted population-rates, with highest rate at 23.8/million/yr and lowest rate at 13.5/mill/yr (for a 176% relative difference; or an absolute difference of +10.3 resections/million/yr). Overall, a lapDP instead of an open DP was 3.5 times more likely in SouthEast compared to all other regions combined (lapDP rate: 83% vrs 24%, respectively; OR 15.4, 95% c.i. 10.1-23.5; P < 0.001). The splenic salvage rate was lower in SouthEast (19.9%) compared to all other regions (average 26.5%; highest in Central-region at 37.0%; P = 0.010 for trend). Controlled for other factors in multivariate regression, 'region' of surgery remained significantly associated with laparoscopic access. CONCLUSION: Despite a universal health care system, considerable variation exists in resection rates, use of laparoscopy and splenic salvage rates across regions.

BACKGROUND: Centralization of pancreatic resections is advocated due to a volume-outcome association. Pancreatic surgery is in Norway currently performed only in five teaching hospitals. The aim was to describe the short-term outcomes after pancreatoduodenectomy (PD) within the current organizational model and to assess for regional disparities. METHODS: All patients who underwent PD in Norway between 2012 and 2016 were identified. Mortality (90 days) and relaparotomy (30 days) were assessed for predictors including demographic data and multi-visceral or vascular resection. Aggregated length-of-stay and national and regional incidences of the procedure were also analysed. RESULTS: A total of 930 patients underwent PD during the study period. In-hospital mortality occurred in 20 patients (2%) and 34 patients (4%) died within 90 days. Male gender, age, multi-visceral resection and relaparotomy were independent predictors of 90-day mortality. Some 131 patients (14%) had a relaparotomy, with male gender and multi-visceral resection as independent predictors. There was no difference between regions in procedure incidence or 90-day mortality. There was a disparity within the regions in the use of vascular resection (p = 0.021). CONCLUSION: The short-term outcomes after PD in Norway are acceptable and the 90-day mortality rate is low. The outcomes may reflect centralization of pancreatic surgery.

BACKGROUND: Distal pancreatectomy (DP) is increasingly done by laparoscopy but data from routine practise are scarce. We describe practise in a national cohort. METHODS: Data from the Norwegian Patient Register of all patients undergoing DP from 2012 to 2016. National resection rates were analysed. Short-term outcomes include length of stay, reoperation, readmissions and 90-day mortality. Risk is reported as odds ratio (OR) with 95% confidence interval (c.i.). RESULTS: Of 554 procedures, 327 (59%) were laparoscopic. Median age was 66 years (iqr 55-72) and 52% were women. Resection rates increased during the period for all DP (from 1.76 to 2.39 per 100.000/yr), and significantly for laparoscopic DP (adjusted R-square 0.858; P = 0.015). Elderly patients had more resection (r2 = 0.11; P = 0.019). Splenectomy (n = 427; 77%) was less likely with laparoscopy (laparoscopy 72% vs open 84%, respectively; OR 0.64, 95% c.i. 0.42-0.97; P = 0.035). Multivisceral resections occurred more often in open DP (5.3% vs 1.2% for laparoscopy, OR 4.51, 1.44-14.2; P = 0.008). Reoperation occurred in 34 (6%), readmission in 109 (20%), and mortality in 8 (1.4%). Hospital stay was shorter for laparoscopic DP. CONCLUSION: Use of DP increases in the population, particularly in the elderly, with use of laparoscopic access and an association with a reduced hospital stay.
