OBJECTIVE:The aim of this study was to develop an alternative fistula risk score (a-FRS) for postoperative pancreatic fistula (POPF) after pancreatoduodenectomy, without blood loss as a predictor.
...BACKGROUND:Blood loss, one of the predictors of the original-FRS, was not a significant factor during 2 recent external validations.
METHODS:The a-FRS was developed in 2 databasesthe Dutch Pancreatic Cancer Audit (18 centers) and the University Hospital Southampton NHS. Primary outcome was grade B/C POPF according to the 2005 International Study Group on Pancreatic Surgery (ISGPS) definition. The score was externally validated in 2 independent databases (University Hospital of Verona and University Hospital of Pennsylvania), using both 2005 and 2016 ISGPS definitions. The a-FRS was also compared with the original-FRS.
RESULTS:For model design, 1924 patients were included of whom 12% developed POPF. Three predictors were strongly associated with POPFsoft pancreatic texture odds ratio (OR) 2.58, 95% confidence interval (95% CI) 1.80–3.69, small pancreatic duct diameter (per mm increase, OR0.68, 95% CI0.61–0.76), and high body mass index (BMI) (per kg/m increase, OR1.07, 95% CI1.04–1.11). Discrimination was adequate with an area under curve (AUC) of 0.75 (95% CI0.71–0.78) after internal validation, and 0.78 (0.74–0.82) after external validation. The predictive capacity of a-FRS was comparable with the original-FRS, both for the 2005 definition (AUC 0.78 vs 0.75, P = 0.03), and 2016 definition (AUC 0.72 vs 0.70, P = 0.05).
CONCLUSION:The a-FRS predicts POPF after pancreatoduodenectomy based on 3 easily available variables (pancreatic texture, duct diameter, BMI) without blood loss and pathology, and was successfully validated for both the 2005 and 2016 POPF definition.

Introduction
Esophagectomy for cancer can be performed in a two-stage procedure with an intrathoracic anastomosis: the Ivor Lewis esophagectomy. A growing incidence of distal and gastroesophageal ...junction adenocarcinomas and increasing use of minimally invasive techniques have prompted interest in this procedure. The aim of this study was to assess short-term results of minimally invasive Ivor Lewis esophagectomy (MIE-IL).
Methods
A retrospective cohort study was performed from June 2007 until September 2014, including patients that underwent MIE-IL for distal esophageal and gastroesophageal junction cancer in six different hospitals in the Netherlands and Spain. Data were collected with regard to operative techniques, pathology and postoperative complications.
Results
In total, 282 patients underwent MIE-IL, of which 90.2 % received neoadjuvant therapy. Anastomotic leakage was observed in 43 patients (15.2 %), of whom 13 patients (4.6 %) had empyema, necessitating thoracotomy for decortication. With an aggressive treatment of complications, the 30-day and in-hospital mortality rate was 2.1 %. An R0-resection was obtained in 92.5 % of the patients. After neoadjuvant therapy, 20.1 % of patients had a complete response.
Conclusions
Minimally invasive Ivor Lewis esophagectomy for distal esophageal and gastroesophageal junction adenocarcinomas is an upcoming approach for reducing morbidity caused by laparotomy and thoracotomy. Anastomotic leakage rate is still high possibly due to technical diversity of anastomotic techniques, and a high percentage of patients treated by neoadjuvant chemoradiotherapy. An aggressive approach to complications leads to a low mortality of 2.1 %. Further improvement and standardization in the anastomotic technique are needed in order to perform a safe intrathoracic anastomosis.

The threshold to perform total pancreatectomy is rather high, predominantly because of concerns for long-term consequences of brittle diabetes on patients’ quality of life. Contemporary data on ...postoperative outcomes, diabetes management, and long-term quality of life after total pancreatectomy from large nationwide series are, however, lacking.
We performed a nationwide, retrospective cohort study among adults who underwent total pancreatectomy in 17 Dutch centers (2006–2016). Morbidity and mortality were analyzed, and long-term quality of life was assessed cross-sectionally using the following generic and disease-specific questionnaires: the 5-level version European quality of life 5-dimension and the European Organization for Research and Treatment in Cancer Quality of Life Questionnaire Cancer. Several questionnaires specifically addressing diabetic quality of life included the Problem Areas in Diabetes Scale 20, the Diabetes Treatment Satisfaction Questionnaire-status version, and the Hypoglycemia Fear Survey-II. Results were compared with the general population and patients with type 1 diabetes.
Overall, 148 patients after total pancreatectomy were included. The annual nationwide volume of total pancreatectomy increased from 5 in 2006 to 32 in 2015 (P < .05). The 30-day and 90-day mortality were 5% and 8%, respectively. The major complication rate was 32%. Quality of life questionnaires were completed by 60 patients (85%, median follow-up of 36 months). Participants reported lower global (73 vs 78, P = .03) and daily health status (0.83 vs 0.87, P < .01) compared to the general population. Quality of life did not differ based on time after total pancreatectomy (<3, 3–5, or >5 years). In general, patients were satisfied with their diabetes therapy and experienced similar diabetes-related distress as patients with type 1 diabetes.
This nationwide study found increased use of total pancreatectomy with a relatively high 90-day mortality. Long-term quality of life was lower compared to the general population, although differences were small. Diabetes-related distress and treatment satisfaction were similar to patients with type 1 diabetes.

To study the feasibility and impact of a nationwide training program in minimally invasive distal pancreatectomy (MIDP).
Superior outcomes of MIDP compared with open distal pancreatectomy have been ...reported. In the Netherlands (2005 to 2013) only 10% of distal pancreatectomies were in a minimally invasive fashion and 85% of surgeons welcomed MIDP training. The feasibility and impact of a nationwide training program is unknown.
From 2014 to 2015, 32 pancreatic surgeons from 17 centers participated in a nationwide training program in MIDP, including detailed technique description, video training, and proctoring on-site. Outcomes of MIDP before training (2005-2013) were compared with outcomes after training (2014-2015).
In total, 201 patients were included; 71 underwent MIDP in 9 years before training versus 130 in 22 months after training (7-fold increase, P < 0.001). The conversion rate (38% n = 27 vs 8% n = 11, P < 0.001) and blood loss were lower after training and more pancreatic adenocarcinomas were resected (7 10% vs 28 22%, P = 0.03), with comparable R0-resection rates (4/7 57% vs 19/28 68%, P = 0.67). Clavien-Dindo score ≥III complications (15 21% vs 19 15%, P = 0.24) and pancreatic fistulas (20 28% vs 41 32%, P = 0.62) were not significantly different. Length of hospital stay was shorter after training (9 7-12 vs 7 5-8 days, P < 0.001). Thirty-day mortality was 3% vs 0% (P = 0.12).
A nationwide MIDP training program was feasible and followed by a steep increase in the use of MIDP, also in patients with pancreatic cancer, and decreased conversion rates. Future studies should determine whether such a training program is applicable in other settings.

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.

In the mandatory nationwide Dutch Pancreatic Cancer Audit, rates of major complications and Failure to Rescue (FTR) after pancreatoduodenectomy between low- and high-mortality hospitals are compared, ...and independent predictors for FTR investigated.
Patients undergoing pancreatoduodenectomy in 2014 and 2015 in The Netherlands were included. Hospitals were divided into quartiles based on mortality rates. The rate of major complications (Clavien-Dindo ≥3) and death after a major complication (FTR) were compared between these quartiles. Independent predictors for FTR were identified by multivariable logistic regression analysis.
Out of 1.342 patients, 391 (29%) developed a major complication and in-hospital mortality was 4.2%. FTR occurred in 56 (14.3%) patients. Mortality was 0.9% in the first hospital quartile (4 hospitals, 327 patients) and 8.1% in the fourth quartile (5 hospitals, 310 patients). The rate of major complications increased by 40% (25.7% vs 35.2%) between the first and fourth hospital quartile, whereas the FTR rate increased by 560% (3.6% vs 22.9%). Independent predictors of FTR were male sex (OR = 2.1, 95%CI 1.2–3.9), age >75 years (OR = 4.3, 1.8–10.2), BMI ≥30 (OR = 2.9, 1.3–6.6), histopathological diagnosis of periampullary cancer (OR = 2.0, 1.1–3.7), and hospital volume <30 (OR = 3.9, 1.6–9.6).
Variations in mortality between hospitals after pancreatoduodenectomy were explained mainly by differences in FTR, rather than the incidence of major complications.

Introduction
The incidence of gallstone disease is increasing and represents a strain on healthcare systems worldwide. Following cholecystectomy, gallbladder specimens are generally submitted for ...histopathologic examination and the diagnostic yield of this strategy remains questionable. This study aimed to evaluate the usefulness of routine pathologic examination of the gallbladder specimens and investigate the results of routine postoperative follow-up visits.
Methods
All cholecystectomies performed between January 2011 and July 2017 at a single center were evaluated. All gallbladder specimens were routinely pathologically examined. The outcome parameters were the macro- and microscopic gallbladder anomalies at pathology and the reported symptoms during routine follow-up visits 2–6 weeks after surgery.
Results
In the study period a total of 2763 patients underwent cholecystectomy, of which 2615 had a postoperative visit in the outpatient clinic. Seventy-three patients (3%) complained of persistent abdominal pain, and 29 of these patients were referred for further treatment, resulting in a resolution of symptoms in 97%. Of all gallbladder specimens, 199 (7%) displayed macroscopic anomalies and in four (2%) of these, gallbladder carcinoma was diagnosed.
Discussion
Selective pathologic examination of gallbladder specimens in case of macroscopic anomalies appears justified. Also routine follow-up after cholecystectomy appears not useful since 97% of patients do not report any symptoms at follow-up. A selective pathology and follow-up strategy could save significant healthcare costs.

Background Microscopically radical (R0) resection of pancreatic, periampullary, or colon cancer may occasionally require a pancreatoduodenectomy with colon resection (PD-colon), but the benefits of ...this procedure have been disputed, and multicenter studies on morbidity and oncologic outcomes after PD-colon are lacking. This study aimed to assess complications and survival after PD-colon. Methods Patients who had undergone PD-colon from 2004–2014 in 1 of 13 centers were analyzed retrospectively. Ninety-day morbidity was scored using the Clavien-Dindo score and the Comprehensive Complication Index (CCI, 0 = no complications, 100 = death). Survival was analyzed per histopathologic diagnosis. Results After screening 3,218 consecutive PDs, 50 (1.6%) PD-colon patients (median age 66 years interquartile range 55–72, 33 66% men) were included. Twenty-three (46%) patients had pancreatic ductal adenocarcinoma (PDAC), 19 (38%) other pathology, and 8 (16%) colon cancer. Ninety-day Clavien-Dindo ≥3 complications occurred in 30 (60%) patients without differences per diagnosis ( P > .99); mean CCI was 39 (standard deviation 27). Colonic anastomosis leak, pancreatic fistula, and 90-day mortality occurred in 3 (6%), 2 (4%), and 4 (8%) patients, respectively. A total of 11/23 (48%) patients with PDAC and 8/8 (100%) patients with colon cancer underwent an R0 resection. Patients with PDAC had a median postoperative survival of 13 months (95% confidence interval = 5–21). One-, 3-, and 5-year cumulative survival was 56%, 21%, and 14%, respectively. Median survival after R0 resection for PDAC was 21 months (95% confidence interval = 6–35). All patients with colon cancer were alive at end of follow-up (median 24 months 95% confidence interval = 9–110). Conclusion In this retrospective, multicenter study, PD-colon was associated with considerable complications and acceptable survival rates when a tumor negative resection margin was achieved.

Background
Large multicenter series on outcomes and predictors of survival after distal pancreatectomy (DP) for pancreatic ductal adenocarcinoma (PDAC) are scarce.
Methods
Adults who underwent DP for ...PDAC in 17 Dutch pancreatic centers between January 2005 and September 2013 were analyzed retrospectively. The primary outcome was survival, and predictors of survival were identified using Cox regression analysis.
Results
In total, 761 consecutive patients after DP were assessed, of whom 620 patients were excluded because of non-PDAC histopathology (
n
= 616) or a lack of data (
n
= 4), leaving a total of 141 patients included in the study 45 % (
n
= 63) male, mean age 64 years (SD = 10). Multivisceral resection was performed in 43 patients (30 %) and laparoscopic resection was performed in 7 patients (5 %). A major complication (Clavien–Dindo score of III or higher) occurred in 46 patients (33 %). Mean tumor size was 44 mm (SD 23), and histopathological examination showed 70 R0 resections (50 %), while 30-day and 90-day mortality was 3 and 6 %, respectively. Overall, 63 patients (45 %) received adjuvant chemotherapy. Median survival was 17 months interquartile range (IQR) 13–21, with a median follow-up of 17 months (IQR 8–29). Cumulative survival at 1, 3 and 5 years was 64, 29, and 22 %, respectively. Independent predictors of worse postoperative survival were R1/R2 resection hazard ratio (HR) 1.6, 95 % confidence interval (CI) 1.1–2.4, pT3/pT4 stage (HR 1.9, 95 % CI 1.3–2.9), a major complication (HR 1.7, 95 % CI 1.1–2.5), and not receiving adjuvant chemotherapy (HR 1.5, 95 % CI 1.0–2.3).
Conclusion
Survival after DP for PDAC is poor and is related to resection margin, tumor stage, surgical complications, and adjuvant chemotherapy. Further studies should assess to what extent prevention of surgical complications and more extensive use of adjuvant chemotherapy can improve survival.
