- Introduction: Tumour related factors are well known as risk factors for survival after pancreatoduodenectomy (PD). In a time when the role for neoadjuvant treatment is discussed also in primary resectable patients, the influence of preoperative variables is of interest. The aim was to examine preoperative factors influence on early mortality following PD.Materials: Patients registered in the Swedish National Registry for Pancreatic and Periampullary Cancer that underwent PD from January 2010 until October 2017, with pancreatic ductal adenocarcinoma and a follow-up of at least 12 months, were included. Univariable and multivariable logistic regression analysis was performed to evaluate preoperatively registered predictors of early death (within 12 months).Results: In total 2,183 pancreatoduodenectomies were performed and 988 patients met the study criteria. The mean age was 67.8 years and 48% were female. A majority had weight loss (59%) and preoperative biliary drainage (78%). 241 (24%) died within 12 months. In univariable analysis age>75 years (p=0.011), CRP>10 mg/L (p=0.008), diabetes (p=0.033), respiratory disorders (p=0.001), and ASA-score >2 (p>0.001) were prognostic factors for early death. In multivariable analysis age>75 years (OR1.66, CI 1.16–2.37, p=0.006), CRP>10 mg/L (OR 1.51, CI 1.10–2.07, p=0.001), diabetes (OR 1.42, CI 1.01–1.99, p=0.045), and respiratory disorders (OR 2.40 CI 1.38–4.18, p=0.002) were independent factors.Discussion: From a national database older age, elevated CRP, diabetes, and respiratory disorders were identified as independent preoperative risk factors for early mortality following PD. This findings may be used in an individualised treatment plan.

- Background and Aims: To investigate the paraclinical and pathological features of surgically resected intraductal papillary mucinous neoplasms in Sweden. Materials and Methods: A review of prospectively collected data on patients undergoing pancreatic resection for a histopathologically verified intraductal papillary mucinous neoplasm between 2010 and 2016 was performed using the Swedish National Registry for Pancreatic and Periampullary Cancer. Results: A total of 3038 pancreatic resections were performed during the study period, of which 251 (8.3%) were due to intraductal papillary mucinous neoplasms. The intraductal papillary mucinous neoplasm cases comprised 227 noninvasive and 24 invasive lesions. There was an annual increase in the number of resected intraductal papillary mucinous neoplasms, from 13 in 2010 to 56 in 2016, and an increase in the proportion of intraductal papillary mucinous neoplasm to the total number of pancreatic resections (4.7%–11%). Biliary obstruction was the only independent predictor of invasive disease, with odds ratio 3.106 (p = 0.030). There was no difference in survival between low-, intermediate-, and high-grade dysplastic lesions (p = 0.417). However, once invasive, the prognosis was severely impacted (p < 0.001). Three-year survival was 90% for noninvasive intraductal papillary mucinous neoplasm and 39% for invasive intraductal papillary mucinous neoplasm. Survival was better in lymph node negative invasive intraductal papillary mucinous neoplasm (p = 0.021), but still dismal compared to noninvasive lesions (p < 0.001). Conclusion: The number of surgically resected intraductal papillary mucinous neoplasms is increasing in Sweden. Biliary obstruction is associated with invasive disease. Low-to-high-grade dysplastic intraductal papillary mucinous neoplasm has an excellent prognosis, while invasive intraductal papillary mucinous neoplasm has a poor survival rate.

- Background and Aims: Pancreatic and periampullary cancers are sometimes found to have a too advanced disease during surgery to allow resection. The aim was to describe characteristics, treatment, outcome, and time trends for patients that were planned for pancreatic surgery but found unresectable during surgery. Material and Methods: Data from the Swedish National Pancreatic and Periampullary Cancer Registry were used. All patients registered between January 2010 and August 2018 were included. The patient cohort was divided in two halves based on year of diagnosis. Results: In total, 12,377 patients were included in the registry and finally 4568 patients were scheduled for surgery. During surgical exploration, 3879 (84.9%) patients underwent pancreatic resection, 658 (14.4%) patients were found unresectable, and 31 (0.7%) had no pancreatic resection due to other reasons (e.g. benign lesion, comorbidity). More patients underwent surgical exploration and resection during the second time period, but exploration without resection was unchanged (15.7% vs 13.7%; p = 0.062). Survival rates were lower among the unresectable patients with pancreatic and periampullary tumors compared to the resectable patients, including 30-day mortality (n = 17 (3.5%) vs n = 39 (1.6%), p = 0.004) and 90-day mortality (n = 72 (15.0%) vs n = 70 (2.8%), p < 0.001). Palliative surgery became less common during the second half of the time period (p < 0.001). Conclusion: Unresectability is associated with an unfavorable prognosis. The frequency did not decrease during the study period, but palliative surgical procedures became less common.

- Background A serious complication after pancreatoduodenectomy (PD) is postoperative pancreatic fistula (POPF). The aim of this study was to analyse the incidence and predictive factors for POPF by using a large nationwide cohort. Methods Data from the Swedish National Registry for Pancreatic and Periampullary Cancer for all patients undergoing a PD from 2010 until 30th June 2018 were collected. The material was analysed in two groups, no POPF and clinically relevant (grade B and C) POPF. Results A total of 2503 patients underwent PD, of which 245 (10%) developed POPF. Patients with POPF had significantly more overall complications (Clavien Dindo >= 3a, 75% vs. 21%,p < 0.001) and longer hospital stay (median 23 [16-35] vs. 11 [8-15],p < 0.001) than patients without POPF. The risk of POPF was higher with increased BMI (OR 1.08,p < 0.001). Preoperative presence of diabetes (OR 0.52,p = 0.012) and preoperative biliary drainage (OR 0.34,p < 0.001) reduced the risk of POPF. Reconstruction with pancreaticojejunostomy caused a more than two folded increase in POPF compared with pancreaticogastrostomy (OR 2.41,p < 0.001). Weight gain >= 2 kg on postoperative day 1 was also a risk factor (OR 1.76,p < 0.001). Conclusion A high BMI, a pancreaticojejunostomy and postoperative weight gain were risk factors for developing POPF. Diabetes or preoperative biliary drainage was protective.

- 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.

- Acute pancreatitis (AP) is a common disease that has a mild to moderate course in most cases. During the last decade, a change in diagnostic facilities as well as improved intensive care have influenced both morbidity and mortality in AP. Still, however, a number of controversies and unresolved questions remain regarding AP. These include prognostic factors and how these may be used to improve outcome, diagnostic possibilities, their indications and optimal timing, and the systemic inflammatory reaction (systemic inflammatory response syndrome - SIRS) and its effect on the concomitant course of the disease and potential development of organ failure. The role of the gut has been suggested to be important in severe AP, but has recently been somewhat questioned. Despite extensive research, pharmacological and medical intervention of proven clinical value is scarce. Various aspects on surgical interventions, including endoscopic sphincterotomy, cholecystectomy and necrosectomy, as regards indications and timing, will be reviewed. Last, but not least, are the management of late complications and long-term outcome for patients with especially severe AP.

- Objective. Peritoneal adhesions develop after almost all surgical interventions in the abdomen. We have developed an efficient treatment against post-surgical adhesions consisting of a combination of positively charged poly-L-lysine and negatively charged poly-L-glutamate. The aim of the present study was to further develop the concept of applying oppositely charged polypeptides in the prevention of adhesion formation, by evaluating different doses of the peptides, alterations in the way of administration, and also testing alternative components. Material and methods. Eighty-five NMRI mice were divided into six groups. A standardized peritoneal injury model was used. The groups received physiologic sodium chlorine, poly-L-lysine + poly-L-glutamate, low molecular weight poly-L-lysine + poly-L-glutamate, locally administered poly-L-lysine + poly-L-glutamate, in vitro mixed poly-L-lysine + poly-L-glutamate and poly-L-arginine + poly-L-glutamate, respectively. After 7 days, the extent of adhesion formation was determined during relaparotomy and was expressed as the mean percentage of the total wound length. Results. A significant decrease (p < 0.001) in the peritoneal adhesion rate was detected in all groups, with the exception of the group administered poly-L-arginine. Among those animals that received poly-L-lysine and poly-L-glutamate, the low dose of poly-L-lysine administration resulted in the most pronounced anti-adhesive effect. Conclusions. The most effective polypeptide combination was poly-L-lysine and poly-L-glutamate, also showing effectiveness when used at low doses and by local application. The differences in adhesion prevention and the possible underlying mechanisms are discussed and the key role of poly-L-lysine is elucidated.
