Summary Background & aims In acute pancreatitis, traditional treatment has been initial fasting on purpose to avoid activation of proteolytic enzymes and pancreatic enzyme secretion. The aim of the ...present study was to evaluate the efficacy and feasibility of immediate oral feeding as compared to traditional fasting in patients with mild acute pancreatitis. Methods Sixty patients were randomized to the two treatment groups, fasting or immediate oral feeding. The inclusion criteria were pancreas amylase ⩾3 times above normal, onset of abdominal pain within 48 h, acute physiological and chronic health evaluation (APACHE) score<8 and C -reactive protein (CRP) <150 mg/L. Outcome measures were pancreas-specific amylase, systemic inflammatory response, feasibility and length of hospital stay (LOHS). Results The groups were comparable with respect to age, sex, etiology, APACHE, time from onset of pain and amylase at admission. No significant differences were seen between the groups concerning levels of amylase, CRP, leukocytes, abdominal pain or number of gastrointestinal symptoms. The LOHS was significantly shorter in the oral feeding group (4 vs. 6 days; p <0.05). Conclusions No signs of exacerbation of the disease process were seen in terms of significant differences between treatment groups for amylase or systemic inflammatory response. In mild acute pancreatitis, immediate oral feeding was feasible and safe and may accelerate recovery without adverse gastrointestinal events.

Pancreatic cancer is one of our most lethal malignancies. Despite substantial improvements in the survival rates for other major cancer forms, pancreatic cancer survival rates have remained ...relatively unchanged since the 1960s. Pancreatic cancer is usually detected at an advanced stage and most treatment regimens are ineffective, contributing to the poor overall prognosis. Herein, we review the current understanding of pancreatic cancer, focusing on central aspects of disease management from radiology, surgery and pathology to oncology.
Registries of pancreatic surgery have become increasingly popular as they facilitate both quality improvement and clinical research. We aimed to compare registries for design, variables collected, ...patient characteristics, treatment strategies, clinical outcomes, and pathology.
Registered variables and outcomes of pancreatoduodenectomy (2014–2017) in 4 nationwide or multicenter pancreatic surgery registries from the United States of America (American College of Surgeons National Surgical Quality Improvement Program), Germany (Deutsche Gesellschaft für Allgemein- und Viszeralchirurgie - Studien-, Dokumentations- und Qualitätszentrum), the Netherlands (Dutch Pancreatic Cancer Audit), and Sweden (Swedish National Pancreatic and Periampullary Cancer Registry) were compared. A core registry set of 55 parameters was identified and evaluated using relative and absolute largest differences between extremes (smallest versus largest).
Overall, 22,983 pancreatoduodenectomies were included (15,224, 3,558, 2,795, and 1,406 in the United States of America, Germany, the Netherlands, and Sweden). Design of the registries varied because 20 out of 55 (36.4%) core parameters were not available in 1 or more registries. Preoperative chemotherapy in patients with pancreatic ductal adenocarcinoma was administered in 27.6%, 4.9%, 7.0%, and 3.4% (relative largest difference 8.1, absolute largest difference 24.2%, P < .001). Minimally invasive surgery was performed in 7.8%, 4.5%, 13.5%, and unknown (relative largest difference 3.0, absolute largest difference 9.0%, P < .001). Median length of stay was 8.0, 16.0, 12.0, and 11.0 days (relative largest difference 2.0, absolute largest difference 8.0, P < .001). Reoperation was performed in 5.7%, 17.1%, 8.7%, and 11.2% (relative largest difference 3.0, absolute largest difference 11.4%, P < .001). In-hospital mortality was 1.3%, 4.7%, 3.6%, and 2.7% (relative largest difference 3.6, absolute largest difference 3.4%, P < .001).
Considerable differences exist in the design, variables, patients, treatment strategies, and outcomes in 4 Western registries of pancreatic surgery. The absolute largest differences of 24.3% for the use of preoperative chemotherapy, 9.0% for minimally invasive surgery, 11.4% for reoperation rate, and 3.4% for in-hospital mortality require further study and improvement. This analysis provides 55 core parameters for pancreatic surgery registries.

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.

Optimal infusion rate of colloids in patients with suspected hypovolemia is unknown, and the primary objective of the present study was to test if plasma volume expansion by 5% albumin is greater if ...fluid is administered slowly rather than rapidly.
Patients with signs of hypoperfusion after major abdominal surgery were randomized to intravenous infusion of 5% albumin at a dose of 10 ml/kg (ideal body weight) either rapidly (30 min) or slowly (180 min). Plasma volume was measured using radiolabeled albumin at baseline, at 30 min, and at 180 min after the start of infusion. Primary outcome was change in plasma volume from the start of infusion to 180 min after the start of infusion. Secondary outcomes included the change in the area under the plasma volume curve and transcapillary escape rate (TER) for albumin from 180 to 240 min after the start of albumin infusion.
A total of 33 and 31 patients were included in the analysis in the slow and rapid groups, respectively. The change in plasma volume from the start of infusion to 180 min did not differ between the slow and rapid infusion groups (7.4 ± 2.6 vs. 6.5 ± 4.1 ml/kg; absolute difference, 0.9 ml/kg 95%CI, - 0.8 to 2.6, P = 0.301). Change in the area under the plasma volume curve was smaller in the slow than in the rapid infusion group and was 866 ± 341 and 1226 ± 419 min ml/kg, respectively, P < 0.001. TER for albumin did not differ and was 5.3 ± 3.1%/h and 5.4 ± 3%/h in the slow and in the rapid infusion groups, respectively, P = 0.931.
This study does not support our hypothesis that a slow infusion of colloid results in a greater plasma volume expansion than a rapid infusion. Instead, our result of a smaller change in the area under the plasma volume curve indicates that a slow infusion results in a less efficient plasma volume expansion, but further studies are required to confirm this finding. A rapid infusion has no effect on vascular leak as measured after completion of the infusion.

Abstract
Background and study aims Single-operator peroral cholangioscopy (SOC) has gained increasing attention in modern biliary and pancreatic therapy and diagnosis. This procedure has shown higher ...rates of infectious complications than conventional endoscopic retrograde cholangiopancreatography (ERCP); therefore, many guidelines recommend antibiotic prophylaxis (AP). However, whether AP administration decreases infectious or overall adverse events (AEs) has been little studied. We aimed to study whether AP affects post-procedure infectious or overall AEs in ERCP with SOC.
Patients and methods We collected data from the Swedish Registry for Gallstone Surgery and ERCP (GallRiks). Of the 124,921 extracted ERCP procedures performed between 2008 and 2021, 1,605 included SOC and represented the study population. Exclusion criteria were incomplete 30-day follow-up, ongoing antibiotic use, and procedures with unspecified indication. Type and dose of antibiotics were not reported. Post-procedure infectious complications and AEs at 30-day follow-up were the main outcomes.
Results AP was administered to 1,307 patients (81.4%). In this group, 3.4% of the patients had infectious complications compared with 3.7% in the non-AP group. The overall AE rates in the AP and non-AP groups were 14.6% and 15.2%, respectively. The incidence of cholangitis was 3.1% in the AP group and 3.4% in the non-AP group. Using multivariable analysis, both infectious complications (odds ratio OR 0.92, 95% confidence interval CI 0.54–1.57) and AEs (OR 0.87, 95% CI 0.65–1.16) remained unaffected by AP administration.
Conclusions No reduction in infectious complication rates and AEs was seen with AP administration for SOC. The continued need for AP in SOC remains uncertain.
Unresectable disease is sometimes diagnosed during surgery in patients with pancreatic ductal adenocarcinoma (PDAC). This study aimed to identify preoperative risk factors for metastatic disease ...diagnosed at surgical exploration and to investigate and compare survival in resected and non-resected patients.
Patients were identified from the Swedish National Pancreatic and Periampullary Cancer Registry 2010-2018. Predictors of metastatic disease were evaluated with a multivariable logistic regression model, and survival was evaluated with Kaplan-Meier estimates and log-rank tests.
In total, 1938 patients with PDAC were scheduled for surgery. An unresectable situation was diagnosed intraoperatively in 399 patients (20.6%), including 234 (12.1%) with metastasized disease. Independent risk factors for metastasis were involuntary weight loss (OR = 1.72; 95% CI: 1.27-2.33) and elevated carbohydrate antigen 19-9 (CA19-9) (35-599 U/mL, OR = 1.79, 95% CI: 1.11-2.89; ≥ 600 U/mL, OR = 3.24, 95% CI: 2.04-5.17). Overall survival was lower among patients with metastasized disease than that among patients with a resectable tumor (P < 0.001).
Involuntary weight loss and an elevation of CA19-9 are preoperative risk factors for diagnosing metastasized disease during surgical exploration.

OBJECTIVE:The aim of the present study was to compare the frequency of readmissions due to small bowel obstruction (SBO) after open versus laparoscopic surgery performed for suspected acute ...appendicitis.
BACKGROUND:Appendicitis is a common disease, with a lifetime risk of approximately 7%. Appendectomy is the treatment of choice for most patients. Postoperative adhesions are common after abdominal surgery, including appendectomy.
MATERIALS AND METHODS:Consecutive patients, 16 years or older, operated on because of suspected appendicitis at 2 university hospitals between 1992 and 2007 were included. The prime approach was open at one hospital and laparoscopic at the other hospital. Open and laparoscopic procedures were compared retrospectively, reviewing the patientsʼ charts until the middle of 2012. Hospitalization for SBO after index surgery was registered.
RESULTS:A total of 2333 patients in the open group and 2372 patients in the laparoscopic group were included. The frequency of hospitalization for SBO was low in both groups, although a difference between the groups was identified (1.0% in the open group and 0.4% in the laparoscopic group) (P = 0.015).
CONCLUSIONS:Hospitalization due to SBO, between open and laparoscopic procedures, in patients operated on because of suspected appendicitis demonstrated a significant difference, favoring the laparoscopic approach. The frequency of SBO after the index surgery was, though, low in both groups.
Total pancreatectomy has high morbidity and mortality and differences among countries are currently unknown. This study compared the use and postoperative outcomes of total pancreatectomy among 4 ...Western countries.
Patients who underwent one-stage total pancreatectomy were included from registries in the United States, Germany, the Netherlands, and Sweden (2014–2018). Use of total pancreatectomy was assessed by calculating the ratio total pancreatectomy to pancreatoduodenectomy. Primary outcomes were major morbidity (Clavien Dindo ≥3) and in-hospital mortality. Predictors for the primary outcomes were assessed in multivariable logistic regression analyses. Sensitivity analysis assessed the impact of volume (low-volume <40 or high-volume ≥40 pancreatoduodenectomies annually; data available for the Netherlands and Germany).
In total, 1,579 patients underwent one-stage total pancreatectomy. The relative use of total pancreatectomy to pancreatoduodenectomy varied up to fivefold (United States 0.03, Germany 0.15, the Netherlands 0.03, and Sweden 0.15; P < .001). Both the indication and several baseline characteristics differed significantly among countries. Major morbidity occurred in 423 patients (26.8%) and differed (22.3%, 34.9%, 38.3%, and 15.9%, respectively; P < .001). In-hospital mortality occurred in 85 patients (5.4%) and also differed (1.8%, 10.2%, 10.8%, 1.9%, respectively; P < .001). Country, age ≥75, and vascular resection were predictors for in-hospital mortality. In-hospital mortality was lower in high-volume centers in the Netherlands (4.9% vs 23.1%; P = .002), but not in Germany (9.8% vs 10.6%; P = .733).
Considerable differences in the use of total pancreatectomy, patient characteristics, and postoperative outcome were noted among 4 Western countries with better outcomes in the United States and Sweden. These large, yet unexplained, differences require further research to ultimately improve patient outcome.

Auditing is an important tool to identify practice variation and ‘best practices’. The Dutch Pancreatic Cancer Audit is mandatory in all 18 Dutch centers for pancreatic surgery.
Performance ...indicators and case-mix factors were identified by a PubMed search for randomized controlled trials (RCT's) and large series in pancreatic surgery. In addition, data dictionaries of two national audits, three institutional databases, and the Dutch national cancer registry were evaluated. Morbidity, mortality, and length of stay were analyzed of all pancreatic resections registered during the first two audit years. Case ascertainment was cross-checked with the Dutch healthcare inspectorate and key-variables validated in all centers.
Sixteen RCT's and three large series were found. Sixteen indicators and 20 case-mix factors were included in the audit. During 2014–2015, 1785 pancreatic resections were registered including 1345 pancreatoduodenectomies. Overall in-hospital mortality was 3.6%. Following pancreatoduodenectomy, mortality was 4.1%, Clavien–Dindo grade ≥ III morbidity was 29.9%, median (IQR) length of stay 12 (9–18) days, and readmission rate 16.0%. In total 97.2% of >40,000 variables validated were consistent with the medical charts.
The Dutch Pancreatic Cancer Audit, with high quality data, reports good outcomes of pancreatic surgery on a national level.
