Abstract
OBJECTIVE To assess metabolic dysfunctions and steatohepatosis after standard and local pancreatic resections for benign and premalignant neoplasms. SUMMARY OF BACKGROUND DATA Duodenopancreatectomy, hemipancreatectomy, and parenchyma-sparing, limited pancreatic resections are currently in use for nonmalignant tumors. METHODS Medline, Embase, and Cochrane libraries were searched for studies reporting measured data of metabolic functions following PD, pancreatic left resection (PLR), duodenum-sparing pancreatic head resection (DPPHR), pancreatic middle segment resection (PMSR), and tumor enucleation (TEN). Forty cohort studies comprising data of 2729 patients were eligible. RESULTS PD for benign tumor was associated in 46 of 327 patients (14.1%) with postoperative new onset of diabetes mellitus (pNODM) and in 109 of 243 patients (44.9%) with postoperative new onset of pancreatic exocrine insufficiency measured after a mean follow-up of 32 months. The meta-analysis displayed pNODM following PD in 32 of 204 patients (15.7%) and in 10 of 200 patients (5%) after DPPHR [P < 0.01; OR: 0.33; (95%-CI: 0.15-0.22)]. PEI was found in 77 of 174 patients following PD (44.3%) and in 7 of 104 patients (6.7%) following DPPHR (P < 0.01;OR: 0.15; 95%-CI: 0.07-0.32). pNODM following PLR was reported in 107 of 459 patients (23.3%) and following PMSR 23 of 412 patients (5.6%) (P < 0.01; OR: 0.20; 95%-CI: 0.12-0.32). Postoperative new onset of pancreatic exocrine insufficiency was found in 17% following PLR and in 8% following PMSR (P < 0.01). pNODM following PPPD and tumor enucleation was observed in 19.7% and 5.7% (P < 0.03) of patients, respectively. Following PD/PPPD, 145 of 608 patients (23.8%) developed a nonalcoholic fatty liver disease after a mean follow-up of 30.4 months. Steatohepatosis following DPPHR developed in 2 of 66 (3%) significantly lower than following PPPD (P < 0.01). CONCLUSION Standard pancreatic resections for benign tumor carry a considerable high risk for a new onset of diabetes, pancreatic exocrine insufficiency and following PD for steatohepatosis. Parenchyma-sparing, local resections are associated with low grade metabolic dysfunctions.

Abstract
INTRODUCTION There is controversy regarding the ideal pancreaticojejunostomy technique after pancreaticoduodenectomy. Many authors consider the external Wirsung stenting technique to be associated with a low incidence of fistula, morbidity and mortality. We analyse our experience with this technique. PATIENTS AND METHODS A retrospective analysis of the morbidity and mortality of a series of 80 consecutive patients who had been treated surgically over a 6.5-year period for pancreatic head or periampullary tumors, performing pancreaticoduodenectomy and pancreaticojejunostomy with external Wirsung duct stenting. RESULTS Mean patient age was 68.3 ± 9 years, and the resectability rate was 78%. The texture of the pancreas was soft in 51.2% of patients and hard in 48.8%. Pylorus-preserving resection was performed in 43.8%. Adenocarcinoma was the most frequent tumor (68.8%), and R0 was confirmed in 70% of patients. Biochemical fistula was observed in 11.2%, pancreatic fistula grade B in 12.5% and C in 2.5%, whereas the abdominal reoperation rate was 10%. Median postoperative hospital stay was 16 days, and postoperative and 90-day mortality was 2.5%. Delayed gastric emptying was observed in 36.3% of patients, de novo diabetes in 12.5%, and exocrine insufficiency in 3. Patient survival rates after 1, 3 and 5 years were 80.2%, 53.6% and 19.2%, respectively. CONCLUSIONS Although our low rates of postoperative complications and mortality using external Wirsung duct stenting coincides with other more numerous recent series, it is necessary to perform a comparative analysis with other techniques, including more cases, to choose the best reconstruction technique after pancreaticoduodenectomy.

Abstract
The distinct biology of pancreatic cancer with aggressive and early invasive tumor cells, a tumor promoting microenvironment, late diagnosis, and high therapy resistance poses major challenges on clinicians, researchers, and patients. In current clinical practice, a curative approach for pancreatic cancer can only be offered to a minority of patients and even for those patients, the long-term outcome is grim. This bitter combination will eventually let pancreatic cancer rise to the second leading cause of cancer-related mortalities. With surgery being the only curative option, complete tumor resection still remains the center of pancreatic cancer treatment. In recent years, new developments in neoadjuvant and adjuvant treatment have emerged. Together with improved perioperative care including complication management, an increasing number of patients have become eligible for tumor resection. Basic research aims to further increase these numbers by new methods of early detection, better tumor modelling and personalized treatment options. This review aims to summarize the current knowledge on clinical and biologic features, surgical and non-surgical treatment options, and the improved collaboration of clinicians and basic researchers in pancreatic cancer that will hopefully result in more successful ways of curing pancreatic cancer.

Abstract
Aim. To study the early postoperative outcomes of duodenum-preserving total pancreatic head resections in benign, premalignant tumors of the pancreatic head and chronic pancreatitis complicated by duodenal dystrophy in comparison with the results of pylorus-preserving pancreaticoduodenectomy. Materials and methods. From 2006 to 2019, 54 patients underwent duodenum-preserving total pancreatic head resection for chronic pancreatitis complicated by duodenal dystrophy, benign or premalignant tumors of the pancreatic head. At the same time, in 25 cases, the operation was performed in an isolated version, in 29 – with a resection of the duodenum. As a comparison group, we used data from 89 patients who underwent pyloruspreserving pancreaticoduodenectomy during the same period. Results. Compared to pancreaticoduodenectomy, duodenum-preserving total pancreatic head resection exhibits significantly longer times for surgery (420 and 310 minutes, respectively). There was no statistically significant difference in the volume of intraoperative blood loss. There are no differences between groups in hospital morbidity (the frequency of pancreatic fistulas, delayed gastric emptying, bile leakage and post-resection bleeding). The frequency of postoperative complications for Clavien-Dindo III and higher did not differ significantly in the groups. There is no hospital mortality after duodenum-preserving total pancreatic head resection; three patients died after pancreatoduodenectomy. Conclusion. Early postoperative outcomes following duodenum-preserving total pancreatic head resection and pylorus-preserving pancreaticoduodenectomy are comparable. However, to develop a full-fledged concept of surgical treatment of pancreatic head benign, premalignant neoplasms and chronic pancreatitis with duodenal dystrophy, it is necessary to analyze the long-term outcomes of treatment.

Abstract
The selection of optimum surgical procedure from the range of reported operations for chronic pancreatitis (CP) can be difficult. The aim of this study is to explore geographical variation in reporting of elective surgery for CP. A systematic search of the literature was performed using the Scopus database for reports of five selected procedures for CP: duodenum-preserving pancreatic head resection, total pancreatectomy with islet autotransplantation (TPIAT), Frey pancreaticojejunostomy, thoracoscopic splanchnotomy and the Izbicki V-shaped resection. The keyword and MESH heading 'chronic pancreatitis' was used. Overall, 144 papers met inclusion criteria and were utilized for data extraction. There were 33 reports of duodenum-preserving pancreatic head resection. Twenty-one (64%) were from Germany. There were 60 reports of TPIAT, 53 (88%) from the USA. There are only two reports of TPIAT from outwith the USA and UK. The 34 reports of the Frey pancreaticojejunostomy originate from 12 countries. There were 20 reports of thoracoscopic splanchnotomy originating from nine countries. All three reports of the Izbicki 'V' procedure are from Germany. There is geographical variation in reporting of surgery for CP. There is a need for greater standardization in the selection and reporting of surgery for patients with painful CP.

Abstract
BACKGROUND Limited literature is available on the development of impaired glucose tolerance and diabetes mellitus after pancreaticoduodenectomy. The primary aim was to define the diabetic phenotype and correlate preoperative glycemic laboratory results to new-onset diabetes after pancreaticoduodenectomy. STUDY DESIGN In this prospective study, perioperative fasting and postprandial (oral glucose tolerance test) plasma glucose, glycated hemoglobin, insulin, and c-peptide were measured in consecutive patients undergoing pancreaticoduodenectomy by the senior author from 2006 to 2017. American Diabetes Association definitions were used for glycemic classifications. Multivariate risk factor analysis was performed. RESULTS Of 774 identified patients, 371 diabetics were excluded and 403 patients were included: 167 and 236 were preoperatively classified as nondiabetic and prediabetic, respectively. The incidence rates of diabetes at 120 months post pancreaticoduodenectomy were 9.0% (nondiabetics), 22.0% (prediabetics), and 16.6% (overall). Patients in whom diabetes developed demonstrated a 3-fold larger difference between oral glucose tolerance test and fasting glucose (Δ), and 2-fold larger Δinsulin and Δc-peptide values. Tiered multivariate analysis identified glycated hemoglobin >5.4% with a relative risk (RR) of 2.944 (p = 0.047) as an independent predictor of impaired glucose tolerance and diabetes mellitus. Analysis of patients stratified by preoperative classification identified fasting glucose >95 mg/dL (nondiabetics, RR 1.925; p = 0.002), and glycated hemoglobin ≥5.4% (prediabetics, RR 3.125; p = 0.040) as independent risk factors for diabetes. Compared with nondiabetics, prediabetics classified by any laboratory results demonstrated an RR of 2.471 (p = 0.001) for diabetes developing postoperatively. There was no association between primary pathology, advancing age, or BMI and increased risk of diabetes development. CONCLUSIONS Diabetes will develop after pancreaticoduodenectomy in approximately 16.6% of patients. A preoperative glycated hemoglobin >5.4% independently predicts new-onset diabetes. Pre- and postoperative endocrine analysis remains paramount for proper patient risk stratification.

Abstract
Pancreaticoduodenectomy and left-sided pancreatectomy are the surgical treatment standards for tumors of the pancreas. Surgeons, who are requested to treat patients with benign tumors, using standard oncological resections, face the challenge of sacrificing pancreatic and extra-pancreatic tissue. Tumor enucleation, pancreatic middle segment resection and local, duodenum-preserving pancreatic head resections are surgical procedures increasingly used as alternative treatment modalities compared to classical pancreatic resections. Use of local resection procedures for cystic neoplasms and neuro-endocrine tumors of the pancreas (panNETs) is associated with an improvement of procedure-related morbidity, when compared to classical Whipple OP (PD) and left-sided pancreatectomy (LP). The procedure-related advantages are a 90-day mortality below 1% and a low level of POPF B+C rates. Most importantly, the long-term benefits of the use of local surgical procedures are the preservation of the endocrine and exocrine pancreatic functions. PD performed for benign tumors on preoperative normo-glycemic patients is followed by the postoperative development of new onset of diabetes mellitus (NODM) in 4 to 24% of patients, measured by fasting blood glucose and/or oral/intravenous glucose tolerance test, according to the criteria of the international consensus guidelines. Persistence of new diabetes mellitus during the long-term follow-up after PD for benign tumors is observed in 14.5% of cases and after surgery for malignant tumors in 15.5%. Pancreatic exocrine insufficiency after PD is found in the long-term follow-up for benign tumors in 25% and for malignant tumors in 49%. Following LP, 14-31% of patients experience postoperatively NODM; many of the patients subsequently change to insulin-dependent diabetes mellitus (IDDM). The decision-making for cystic neoplasms and panNETs of the pancreas should be guided by the low surgical risk and the preservation of pancreatic metabolic functions when undergoing a limited, local, tissue-sparing procedure.

Abstract
The metrics for measuring early postoperative morbidity after resection of pancreatic neoplastic tumors are overall morbidity, severe surgery-related morbidity, frequency of reoperation and reintervention, in-hospital, 30-day and 90-day mortality and length of hospital stay. Thirty-day readmission after discharge is additionally an indispensable criterion to assess quality of surgery. The metrics for surgery-associated long-term results after pancreatic resections are survival times, new onset of diabetes (DM), impaired glucose tolerance, exocrine pancreatic insufficiency, body mass index and GI motility dysfunctions. Following pancreaticoduodenectomy (PD) performed on pancreatic normo-glycemic patients for malignant and benign tumors, 4-30% develop postoperative new onset of diabetes. Long-term persistence of diabetes mellitus is observed after surgery for benign tumors in 14% and in 15.5% of patients after cancer resection. Pancreatic exocrine insufficiency after PD is observed in the early postoperative period in 23-80% of patients. Persistence of exocrine dysfunctions exists in 25% and 49% of patients. Following left-sided pancreatic resection, new onset DM is observed in 14% of cases; an exocrine insufficiency persisting in the long-term outcome is observed in 16-28% of patients.

Abstract
Pancreaticoduodenectomy (Whipple's procedure) remains the only definitive treatment option for tumors of the periampullary region. The most common and life-threatening complications following the procedure are pancreatic anastomotic leakage and subsequent fistula formation. When these complications occur, treatment strategy depends on the severity of anastomotic leakage, with patients with severe leakages requiring reoperation. The optimal surgical method used for reoperation is selected from among different options such as wide drainage, definitive demolition of the pancreaticojejunal anastomosis and performing a new one, or completion pancreatectomy. Here we present a novel, simple technique to manage severe pancreatic leakage via ligamentum teres hepatis patch.

Abstract
Cystic neoplasms and neuroendocrine adenomas of the pancreas are detected increasingly more frequently and in up to 50 % as asymptomatic tumors. Intraductal papillary mucinous neoplasms, mucinous cystic neoplasms and solid pseudopapillary neoplasms are considered to be premalignant lesions with different rates of malignant transformation. The most frequent neuroendocrine adenomas are insulinomas. Neuroendocrine adenomas are considered to be potentially malignant, inherent to the lesion and development is unpredictable. Standard surgical treatment for pancreatic tumors are the Kausch-Whipple resection, left hemipancreatectomy and total pancreatectomy depending on the location; however, the application of standard surgical procedures, which are usually multiorgan resections for benign, premalignant and low-risk cancers of the pancreas have to be balanced against the risk for early postoperative morbidity, hospital mortality of 1.5-7 % and loss of endocrine and exocrine pancreatic functions in 12-30 %. Tumor enucleation, pancreatic middle segment resection and duodenum-preserving total pancreatic head (DPPHR-T/S) resection are parenchyma-preserving, local resection procedures, which are associated with a low early postoperative rate of severe complications, hospital mortality up to 1.3 % and maintenance of exocrine and endocrine pancreatic functions in more than 90 %. Tumor enucleation bears the risk of pancreatic fistulas (<33 %) and a limitation is proximity to the pancreatic main duct. The main risk for pancreatic middle segment resection is early postoperative pancreatic fistulas (up to 40 %), early postoperative intra-abdominal hemorrhage and a reintervention frequency up to 15 %. The DPPHR-T/S resection is applied for cystic neoplastic lesions in 90 %, severe postoperative complications are below 15 % and the 90-day hospital mortality is 0.5 %. Pancreatic fistulas are observed in less than 20 % with a recurrence rate of <1 %. These facts and maintenance of exocrine and endocrine pancreatic functions are advantages compared with the Kausch-Whipple resection of the pancreatic head. The use of tumor enucleation, particularly for neuroendocrine tumors and pancreatic middle segment resection as well as total DPPHR resection should replace the pancreatoduodenectomy for lesions in the pancreatic head and hemipancreatectomy for lesions in the pancreatic body and tail.

Abstract
BACKGROUND Potential benefits of local extirpation of benign pancreatic head tumors are tissue conservation of pancreas, stomach, duodenum and common bile duct (CBD) and maintenance of pancreatic functions. METHODS Medline/PubMed, Embase and Cochrane Library databases were searched to identify studies applying duodenum-preserving total or partial pancreatic-head resection (DPPHRt/p) and reporting short- and long-term outcomes. Twenty-four studies, including 416 patients who underwent DPPHRt/p, were identified for systematic analysis. The meta-analysis was based on 10 prospective controlled and 4 retrospective controlled cohort studies, comparing 293 DPPHRt/p resections with 372 pancreato-duodenectomies (PD). RESULTS, SYSTEMATIC ANALYSIS Of 416 patients, 75.7% underwent total and 24.3% partial head resection, while 47.1% included segmentectomy of duodenum and CBD. The most common pathology was cystic neoplasm (65.8%) and endocrine tumors (13.4%). The frequencies of severe postoperative complications of 8.8%, pancreatic fistula of 19.2%, re-operation of 1.7% and hospital mortality of 0.48%, indicate a low level of early post-operative complications. META-ANALYSIS DPPHRt/p significantly preserved the level of exocrine (IV = -0.67, 95% CI -0.98 to -0.35, p = 0.0001) and endocrine (IV = 18.20, fixed, 95% CI -0.92 to 25.48, p = 0.0001) pancreatic functions compared to PD when the pre- and postoperative functional status in both groups are analyzed. There were no significant differences between DPPHRt/p and PD in frequency of pancreatic fistula, delayed gastric emptying or hospital mortality. CONCLUSION DPPHRt/p for benign neoplasms and neuro-endocrine tumors of the pancreatic head is associated with a low level of early-postoperative complications and a better conservation of exocrine and endocrine functions.

External stent versus no stent for pancreaticojejunostomy: a meta-analysis of randomized controlled trials. J Gastrointest Surg 2013; 17:1516-25. [PMID: 23568149 DOI: 10.1007/s11605-013-2187-4] [Citation(s) in RCA: 52] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2013] [Accepted: 03/18/2013] [Indexed: 01/31/2023]
Abstract
BACKGROUND The effectiveness of an external pancreatic duct stent for reduction of the pancreatic fistula after pancreaticoduodenectomy remains controversial. METHODS MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials were searched for eligible randomized controlled trials (RCTs). Reviews of each trial were conducted and data were extracted. The primary outcome was pancreatic fistula. Statistical pooling used the fixed or random effects model and reported as risk ratio (RR) or mean difference (MD) with the corresponding 95 % confidence intervals (CI). RESULTS Four RCTs including a total of 416 patients were detected. Methodological quality assessment revealed a better quality of all analyzed trials. Placing an external stent across pancreaticojejunal anastomosis could significantly reduce the incidence of pancreatic fistula (RR = 0.57, 95 % CI = 0.41-0.80, P = 0.001, I (2) = 0 %), overall morbidity (RR = 0.79, 95 % CI = 0.64-0.98, P = 0.03), and the length of hospital stay (MD = -3.98 days, 95 % CI = -6.42 to -1.54, P = 0.001, I (2) = 13 %). No significant difference was found in terms of hospital mortality, delayed gastric emptying, operation time, operative blood loss, blood replacement, and reoperation rate. CONCLUSIONS This meta-analysis provides compelling evidence that the application of an external pancreatic duct stent after pancreaticoduodenectomy can decrease the incidence of pancreatic leakage when compared with no stent. Moreover, the external drainage of pancreatic juice is associated with lower postoperative overall morbidity and shorter hospital stay.

Abstract
PURPOSE Although C-reactive protein (CRP) can be measured by a standard blood test, its diagnostic value for distinguishing patients with inflammatory complications after pancreatic surgery from patients with normal postoperative inflammatory responses has not been adequately investigated. This study aimed to assess the diagnostic accuracy of CRP levels for the occurrence of postoperative inflammatory complications after pancreatic surgery. METHODS Clinical data and CRP levels measured in 280 patients after pancreatic surgeries (performed between 1998 and 2010) until postoperative day 10 (POD 10) were retrospectively analyzed. Using the receiver operating characteristic method, diagnostic accuracy was evaluated by an area under the curve (AUC) analysis. Furthermore, the results of the present study were compared to previously published reports by applying diagnostic meta-analysis techniques. RESULTS The 30-day mortality rate was 3.9% (95% CI 2.1-7.0%). Inflammatory complications occurred in 153 of 280 patients (54.6%; 95% CI 48.8-60.4%). On POD 4, the AUC was 0.67 (95% CI 0.58-0.76). The highest diagnostic accuracy was observed on POD 7 (AUC 0.77; 95% CI 0.68-0.85). In a diagnostic meta-analysis that included two additional studies, the diagnostic sensitivity on POD 4 was 0.63 (95% CI 0.50-0.76), and the specificity was 0.79 (95% CI 0.71-0.88). The highest sensitivity occurred on POD 6 (0.75; 95% CI 0.68-0.82). Considerable statistical heterogeneity was observed in the analysis of PODs 3, 4 and 5. CONCLUSION According to this limited evidence, CRP levels had a low to moderate diagnostic accuracy. Large, blinded studies are warranted for a more precise estimation of CRP's diagnostic value.

Abstract
BACKGROUND A stent often is placed across the pancreaticojejunostomy. However, there is no report compared between internal drainage and external drainage. METHODS We conducted a prospective randomized trial (NCT00628186 registered at http://ClinicalTrials.gov) with 100 patients who underwent pancreaticoduodenectomy and we compared the effects on postoperative course. RESULTS The incidence of pancreatic fistula according to the International Study Group on Pancreatic Fistula criteria was not different (external, 20%; vs internal, 26%), and the incidence of the other complications was similar between stent types. The median postoperative hospital stay was 21 days (range, 8-163 d) in the internal drainage group, which was shorter than the median stay of 24 days (range, 21-88 d) in the external drainage group (P = .016). CONCLUSIONS Both internal drainage and external drainage were safety devices for pancreaticojejunostomy. Internal drainage simplifies postoperative managements and it might shorten postoperative stay for pancreaticoduodenectomy.

Abstract
BACKGROUND Leakage from the pancreaticojejunostomy is the major cause of septic complications after partial pancreaticoduodenectomy. This study evaluated a new transpancreatic U-suture technique (Blumgart anastomosis, BA), which aims to avoid shear forces during knot-tying. METHODS Using a before-after study design, BA was compared with a modified Cattell-Warren anastomosis (CWA). Two patient cohorts (CWA, 90; BA, 92), which were similar with respect to primary diagnosis, age, sex and American Society of Anesthesiologists score, were compared retrospectively. Dependent variables were surgical and overall morbidity and mortality after partial pancreaticoduodenectomy. RESULTS Duration of operation (354 versus 328 min for CWA versus BA; P = 0.002), pancreatic leakage rate (13 versus 4 per cent; P = 0.032), postoperative haemorrhage (11 versus 3 per cent; P = 0.040), total surgical complications (31 versus 15 per cent; P = 0.011), general complications (36 versus 17 per cent; P = 0.005) and length of intensive care unit stay (median 5.4 versus 2.8 days; P = 0.015) were significantly reduced after BA. These effects were not related merely to an improvement over time. CONCLUSION BA appears to be a fast, simple and safe technique for pancreaticojejunostomy. It might reduce leakage rates and surgical complications after partial pancreaticoduodenectomy.

Abstract
BACKGROUND AND AIMS Significant progress in surgical technique and perioperative management has substantially reduced the mortality rate of pancreatic surgery. However, morbidity remains considerably high, even in expert hands and leakage from the pancreatic stump still accounts for the majority of surgical complications after pancreatic head resection. For that reason, management of the pancreatic remnant after partial pancreatoduodenectomy remains a challenge. This review will focus on technique, pitfalls, and complication management of pancreaticoenteric anastomoses. MATERIALS AND METHODS A medline search for surgical guidelines, prospective randomized controlled trials, systematic metaanalysis, and clinical reports was performed with regard to surgical technique and complication management of pancreatic anastomoses. RESULTS Pancreaticojejunostomy appears to be most widely performed, but pancreaticogastrostomy is a reasonable alternative. Postoperative treatment with octreotide can be recommended only for patients with soft pancreatic tissue, and neither stents of the pancreatic duct nor drainages have proven to effectively reduce anastomotic complications. Gastroparesis remains the most common complication after pancreatic surgery and should be treated conservatively. However, it may be a symptom of other local complications, such as anastomotic leakage, pancreatic fistula or abscess. All septic complications may finally result in late postoperative hemorrhage, which requires immediate diagnostic workup and therapy. Today, interventional radiology has emerged as a standard tool in the management of local septic complications and bleeding. Therefore, relaparotomy has become less frequent and salvage pancreatectomy is now a rare procedure in case of local complications. CONCLUSION The surgeon's experience with one or the other technique of pancreatic anastomosis appears to be more important than the technique itself.
