    Abstract Background: Delayed gastric emptying (DGE) is a common complication after pancreatoduodenectomy (PD). DGE causes prolonged hospital stay and a decrease in quality of life. This study analyzes predictive factors for development of DGE after PD, also in the absence of surgical complications.
    Method: Data from the Swedish National Pancreatic Cancer Registry for patients undergoing standard and pylorus preserving open PD from January 2010 until June 30, 2018, were collected. Data were analyzed in two groups, no DGE and DGE. A subgroup of patients with DGE but without surgical complications was compared to patients without DGE or any other surgical complication.
    Results: In total, 2503 patients were included, of which 470 (19%) had DGE. In the DGE group, 238 had other coexisting surgical complications and 232 had not. Postoperative pancreatic fistula (OR = 4.22, p < 0.001), surgical infection (OR = 1.44, p = 0.013), heart disease (OR = 1.32, p = 0.023) and medical complications (OR = 1.35, p = 0.025) increased the risk for DGE. A standard PD compared with pylorus preserving resection (OR = 1.69, p = 0.001) and a reconstruction with a pancreaticojejunostomy compared with a pancreaticogastrostomy (OR = 1.83, p < 0.001) increased the risk. For patients without surgical complications, a standard PD and reconstruction with pancreaticojejunostomy still increased the risk for DGE.
    Conclusion: DGE is more common after standard PD compared to pylorus preserving PD and after reconstruction with PJ compared to PG in this national cohort, both in the presence of other surgical complications as well as in the absence of other complications.

    Abstract Background: Hyperglycemia is a risk factor for postoperative complications but its impact on outcome after pancreatoduodenectomy (PD) is scarcely studied. This prospective cohort study aimed to assess the effect of continuous insulin infusion on postoperative complications and blood glucose, as well as to evaluate the impact of hyperglycemia on complications, after PD.
    Materials and methods: One hundred patients planned for PD at Skåne University Hospital, Sweden were prospectively included for perioperative continuous insulin infusion and a historic cohort of 100 patients was included retrospectively. Median blood glucose levels were calculated and data on complications were analyzed and compared between the historic cohort and the intervention group as well as between normo- and hyperglycemic patients.
    Results: Median glucose levels were significantly lower in the intervention group compared to the historic cohort up to 30 days postoperatively (median glucose 8.5 mmol/l (interquartile range 6.4-11) vs. 9.1 mmol/l (interquartile range 6.8-17) ( P =0.007)). No significant differences in complication rates were recorded between these two groups. The incidence of complications classified as Clavien ≥3 was higher in hyperglycemic patients (100 vs. 27%, P =0.024). Among hyperglycemic patients the prevalence of preoperative diabetes was higher compared to normoglycemic patients (52 vs.12%, P <0.001). In patients with a known diagnosis of diabetes, a trend, although not statistically significant, towards a lower incidence of postoperative pancreatic fistula grade B and C, as well as postpancreatectomy hemorrhage grade B and C, was seen compared to those without preoperative diabetes (6.8 vs. 14%, P =0.231 and 2.3 vs. 7.0%, P =0.238, respectively).
    Conclusion: Insulin infusion in the early postoperative phase after PD is feasible in a non-ICU setting and significantly decreased blood glucose levels. The influence on complications was limited. Preoperative diabetes was a significant predictor of postoperative hyperglycemia and was associated with a lower incidence of clinically significant postoperative pancreatic fistula.

    Abstract Background: Resection margin has been associated with overall survival following liver resection for colorectal liver metastasis. The aim of this study was to examine how resection margins of 0.0 mm, 0.1-0.9 mm and ≥1 mm influence overall survival in patients resected for colorectal liver metastasis in a time of modern perioperative chemotherapy and surgery.
    Methods: Using data from the national registries Swedish Colorectal Cancer Registry and Swedish National Quality Registry for Liver, Bile Duct and Gallbladder Cancer, patients that had liver resections for colorectal liver metastasis between 2009 and 2013 were included. In patients with a narrow or unknown surgical margin the original pathological reports were re-reviewed. Factors influencing overall survival were analysed using a Cox proportional hazard model.
    Results: A total of 754 patients had a known margin status, of which 133 (17.6%) patients had a resection margin <1 mm. The overall survival in patients with a margin of 0 mm or 0.1-0.9 mm was 42 (95% c.i. 31 to 53) and 48 (95% c.i. 35 to 62) months respectively, compared with 75 (95% c.i. 65 to 85) for patients with ≥1 mm margin, P < 0.001. Margins of 0 mm or 0.1-0.9 mm were associated with poor overall survival in the multivariable analysis, HR 1.413 (95% c.i. 1.030 to 1.939), P = 0.032, and 1.399 (95% c.i. 1.025 to 1.910), P = 0.034, respectively.
    Conclusions: Despite modern chemotherapy the resection margin is still an important factor for the survival of patients resected for colorectal liver metastasis, and a margin of ≥1 mm is needed to achieve the best possible outcome.

    Abstract Aims: Intermittently scanned continuous glucose monitoring (isCGM) systems have not been thoroughly evaluated during in-hospital stay, and there are concerns about accuracy during various conditions. Patients undergoing pancreatoduodenectomy have an increased risk of hyperglycaemia after surgery which is aggravated by parenteral nutrition therapy. This study aims to evaluate glycaemic control and safety during insulin infusion in a surgical non-ICU ward, using a hybrid glucose monitoring approach with isCMG and periodic point-of-care (POC) testing.
    Methods: We prospectively included 100 patients with a resectable pancreatic tumour. After surgery, continuous insulin infusion was initiated when POC glucose was > 7 mmol/l and titrated to maintain glucose between 7 and 10 mmol/l. Glucose was monitored with isCGM together with intermittent POC, every 3-6 h. Median absolute relative difference (MARD) and hypoglycaemic events were evaluated. Mean glucose was compared with a historic control (n = 100) treated with multiple subcutaneously insulin injections, monitored with POC only.
    Results: The intervention group (isCGM/POC) had significantly lower POC glucose compared with the historic control group (8.8 ± 2.2 vs. 10.4 ± 3.4 mmol/l, p < 0.001). MARD was 17.8% (IQR 10.2-26.7). isCGM readings were higher than POC measurements in 91% of the paired cases, and isCGM did not miss any hypoglycaemic event. About 4.5% of all isCGM readings were < 3.9 mmol/l, but only six events were confirmed with POC, and none was < 3.0 mmol/l.
    Conclusions: A hybrid approach with isCGM/POC is a safe and effective treatment option in a non-ICU setting after pancreatoduodenectomy.

    Abstract Background: Little is known of possible gender differences in treatment of periampullary tumours and outcome after pancreatoduodenectomy (PD), and the aim of this study was therefore to investigate any variances from national multicentre perspective.
    Methods: Data from the Swedish National Registry for Pancreatic and Periampullary Cancer for all patients diagnosed with a periampullary tumour from 2012 throughout 2017 was collected. The material was analysed in two groups, men and women, for palliative treatment and curative intended resection.
    Results: A total of 5677 patients were included, 2906 (51%) men and 2771 (49%) women. Women were older than men, 72 (65-78) years vs. 70 (64-76), p < 0.001. A lesser proportion of women were planned for resection (1131 (41%) vs. 1288 (44%), p = 0.008), but after adjusting for age and tumour location no difference was seen. Postoperative morbidity was equal, but women had significantly better long-term survival than men. The survival was equal for palliative men and women.
    Conclusion: No gender bias could be established when analysing treatment for periampullary tumours in Sweden, even though less women were offered surgery. Data suggest that even though women were older they tolerate surgery well and hence offering PD at a higher age for women could be suggested.

    Abstract Background and aims: To validate the Swedish Register for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks) concerning completeness and correctness of entered data for cholecystectomies and evaluating the effect of repeated audits. It is crucial for any register to obtain a high accuracy in order to be a credible and reliable source for quality evaluation, research, and development.
    Materials and methods: Completeness was determined by cross-matching the register with the Swedish National Patient Register. Completeness and overall correctness were assessed by comparing registered data to medical records. Correctness for rare occasions, such as bile duct injuries, was evaluated by comparing with claims sent to the Swedish Patient Insurance.
    Results: Of 64,538 cholecystectomies, 82.9% of the operations were registered in GallRiks and the coverage increased over time. By random sample, 94,919 sets of data were available for comparison at the first and second audit and the entries were found to be correct in 97.2% and 98.2% cases, respectively. A 100% correctness for bile duct injuries (n = 40) was seen when the index-operation was registered in GallRiks.
    Conclusion: GallRiks demonstrates high completeness, high correctness of entered data, and no indications of failure to report serious adverse events. Repeated audits increased the quality of registered data. GallRiks may be used for clinical evaluation on local and national level and the database enables scientific studies to be performed.

    Abstract Objectives: Reports on quality-of-life (QoL) after bile duct injury (BDI) show conflicting results. The aim of this cohort study was to evaluate QoL stratified according to type of treatment.
    Methods: QoL assessment using the SF-36 (36-item short form health survey) questionnaire. Patients with post-cholecystectomy BDI needing hepaticojejunostomy (HJ) were compared to all other treatments (BDI repair) and to patients without BDI at cholecystectomy (controls).
    Results: Patients needing a HJ after BDI reported reduced long-term QoL irrespective of time for diagnosis and repair in both the physical (PCS;
    Conclusions: Patients with postoperative diagnosis and patients with BDIs needing biliary reconstruction with HJ both reported reduced long-term QoL.

    Abstract Background: Pancreatoduodenectomy is associated with a high risk of complications. The aim was to identify preoperative risk factors for major intraoperative bleeding.
    Methods: Patients registered for pancreatoduodenectomy in the Swedish National Pancreatic and Periampullary Cancer Registry, 2011 to 2016, were included. Major intraoperative bleeding was defined as ≥1000 ml. Univariable and multivariable analysis of preoperative parameters were performed.
    Results: In total, 1864 patients were included. The median blood loss was 600 ml, and 502 patients (27%) had registered bleeding of ≥1000 ml. Preoperative independent risk factors associated with major bleeding were male sex (p < 0.001), body mass index (BMI) ≥25 kg/m
    Conclusion: Most predictive parameters for major intraoperative bleeding are not modifiable. PBD is an independent predictor for major intraoperative bleeding and to reduce the risk, patients with resectable periampullary tumors should, if possible, be subject to surgery without preoperative biliary drainage.

    Abstract Background: Bile duct injury (BDI) is a rare complication associated with cholecystectomy, and recommendations for treatment are based on publications from referral centers with a selection of major injuries and failures after primary repair. The aim was to analyze the frequency, treatment, and outcome of BDIs in an unselected population-based cohort.
    Methods: This was a retrospective cohort study including all BDIs registered in GallRiks (Swedish quality register for gallstone surgery and ERCP) during 2007-2011. Data for this study were based on a national follow-up survey where medical records were scrutinized and BDIs classified according to the Hannover classification.
    Results: A total of 174 BDIs arising from 55,134 cholecystectomies (0.3%) identified at 60 hospitals were included with a median follow-up of 37 months (9-69). 155 BDIs (89%) were detected during cholecystectomy, and immediate repair was attempted in 140 (90%). A total of 27 patients (18%) were referred to a HPB referral center. Hannover Grade C1 (i.e., small lesion <5 mm) dominated (n = 102; 59%). The most common repair was "suture over T-tube" (n = 78; 45%) and reconstruction with hepaticojejunostomy was performed in 30 patients (17%). A total of 31 patients (18 %) were diagnosed with stricture, 19 of which were primarily repaired with "suture over T-tube." The median in-hospital-stay was 14 days (1-149).
    Conclusions: The majority of BDIs were detected during the cholecystectomy and repaired by the operating surgeon. Although this is against most current recommendations, short-term outcome was surprisingly good.
