Chui JN, Sahni S, Samra JS, Mittal A. Postoperative pancreatitis and pancreatic fistulae: a review of current evidence. HPB (Oxford) 2023; 25:1011-1021. [PMID: 37301633 DOI: 10.1016/j.hpb.2023.05.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2023] [Revised: 04/28/2023] [Accepted: 05/09/2023] [Indexed: 06/12/2023]
Abstract
OBJECTIVES Postoperative pancreatic fistula (POPF) represents one of the most severe complications following pancreatic surgery. Despite being a leading cause of morbidity and mortality, its pathophysiology is poorly understood. In recent years, there has been growing evidence to support the role of postoperative or post-pancreatectomy acute pancreatitis (PPAP) in the development of POPF. This article reviews the contemporary literature on POPF pathophysiology, risk factors, and prevention strategies. METHODS A literature search was conducted using electronic databases, including Ovid Medline, EMBASE, and Cochrane Library, to retrieve relevant literature published between 2005 and 2023. A narrative review was planned from the outset. RESULTS A total of 104 studies fulfilled criteria for inclusion. Forty-three studies reported on technical factors predisposing to POPF, including resection and reconstruction technique and adjuncts for anastomotic reinforcement. Thirty-four studies reported on POPF pathophysiology. There is compelling evidence to suggest that PPAP plays a critical role in the development of POPF. The acinar component of the remnant pancreas should be regarded as an intrinsic risk factor; meanwhile, operative stress, remnant hypoperfusion, and inflammation represent common mechanisms for acinar cell injury. CONCLUSIONS The evidence base for PPAP and POPF is evolving. Future POPF prevention strategies should look beyond anastomotic reinforcement and target underlying mechanisms of PPAP development.

Abstract
The OBJECTIVE was to improve the results of pancreatoduodenal resection by reducing the incidence of pancreatoenteroanastomotic leak and postoperative pancreatitis with a «soft» pancreatic stump.METHODS AND MATERIALS. A new method for the formation of pancreatoenteroanastomosis has been developed and implemented: precision wirsungojejunoanastomosis with additional wide atraumatic peritonization of the pancreatic stump cutoff with the loop of the small intestine. From February 2016 to March 2018, this method was tested in 18 patients.RESULTS. Pancreatoenteroanastomotic leak of class A was noted in 2 (11.1 %) patients, was transient, asymptomatic, did not require additional medical measures and did not extend the duration of the postoperative period. There were no pancreatoenteroanastomotic leak of classes B and C, pancreonecrosis of the stump, lethal outcomes. Objectively worst statistical results were obtained in the comparison group.CONCLUSION. The formation of the small intestine anastomosis with a «soft» pancreatic stump according to the proposed method for pancreatoduodenal resection reduces the incidence of postoperative pancreatitis of the stump and pancreatoenteroanastomotic leak.

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
BACKGROUND Postoperative pancreatic fistula (POPF) is one of the most severe complications after cephalic pancreaticoduodenectomy, with mortality as high as 30%. Risk scores may help predict the risk of POPF. Multiple external validations substantially improve generalized clinical acceptability of a scoring system. AIM The aim of this study was to externally validate previously described fistula risk score in the prediction of clinically relevant POPF. METHODS All patients who underwent pancreaticoduodenectomy for any indication during a 5-year period were prospectively analyzed. A total of 132 patients were analyzed. RESULTS Of the 132 patients, 44 (33.3%) developed pancreatic fistula, including 12.9% biochemical leaks, 7.6% grade B fistula, and 12.9% grade C fistula. Cut-off point of 4.5 was determined to best separate patients who developed clinically relevant POPF with area under curve of 78% (p = .00003). Sensitivity and specificity for the prediction of clinically relevant POPF with the cut-off value of 4.5 was 70.4 and 74.3%, respectively. Positive predictive value with cut-off value 4.5 was 57.8%, and negative predictive value was 83.4%. CONCLUSION Fistula risk score identified low risk patients with false negative rate of 16.6%. Further external validation studies on large cohorts of patients and with wide case-mix may enable additional refinements of the score model.

Abstract
This review is devoted to history of pancreatodigestive anastomoses (PDA), technique of the most popular PDA, causes of pancreatic fistula and its prevention. Contradictory data were obtained in randomized trials and meta-analyses devoted to pancreatic anastomoses. There is no optimal anastomosis excluding clinically significant postoperative pancreatic fistula. Therefore, further studies should be aimed at new approaches reducing the incidence of clinically significant postoperative pancreatic fistula.

Abstract
INTRODUCTION Pancreaticoduodenectomy (PD) has been widely applied as a standard surgical procedure to treat periampullary diseases. The placement of a pancreaticojejunal anastomotic stent is considered an effective and safe method for preventing pancreatic fistula after PD. Recently, the role of pancreaticojejunal anastomotic stents has been challenged, as gradually increasing complications have been observed. Stent-related small bowel perforation has only occurred in 2 cases as long-term complications but has not been reported to occur within 1 week after surgery. PATIENT CONCERNS Here, we report the case of a 71-year-old female patient complaining of painless jaundice who underwent PD with a pancreaticojejunal anastomotic stent for a duodenal papillary adenocarcinoma (T4N1M0). Four days after surgery, she had a sudden rise in temperature, high white blood cell count, significantly elevated C-reactive protein and 400 ml green-brown drainage fluid. Enhanced computed tomography showed hydrops abdominis. DIAGNOSIS Small bowel perforation caused by stent migration was considered first. INTERVENTIONS An emergency exploratory laparotomy was performed. We located the pancreaticojejunal anastomotic stent, which extended 2 cm from the small bowel, and sutured the jejunum hole after cutting away the protruding part of the stent. OUTCOMES The patient recovered smoothly and was discharged on the 7th day after the second surgery. After more than 12 months of follow-up, the patient is doing well and is free of any symptoms related to the procedure. CONCLUSION We caution that stent-related complications can occur when perioperative patients suffer from unexplained or sudden changes in vital signs after PD. In addition, the function of the pancreaticojejunal anastomotic stent needs to be reevaluated by future studies.

Abstract
INTRODUCTION Laparoscopic pancreatic reconstruction is a challenging procedure and is considered the Achilles' heel of laparoscopic pancreatectomy. Multiple techniques of laparoscopic pancreatic reconstruction have been reported, but the optimal technique remains unclear. AREAS COVERED This paper provides a brief introduction to the developmental status and major related complications of laparoscopic pancreatic reconstruction. We reviewed all published literature on the technology of laparoscopic pancreatic reconstruction within the last 5 years and herein discuss the advantages and disadvantages of different reconstruction methods. We also discuss several details of different reconstruction techniques in terms of their significance to the operation and complications. EXPERT OPINION No individual method of laparoscopic pancreatic reconstruction is considered optimal for all conditions. The reconstruction strategy should be based on the surgeon's proficiency with laparoscopic technology and the patient's individual risk factors. Personalized methods of pancreatic reconstruction may more effectively reduce morbidity and mortality.

Abstract
BACKGROUND There is no specific evidence regarding the benefits of external and internal pancreatic duct stents after pancreaticoduodenectomy since pancreatic fistula (grade A) have been redefined with no clinical treatment effect. We aimed to reevaluate the prognostic value of external and internal stents in clinically relevant postoperative pancreatic fistula over pancreaticoduodenectomy. METHODS PubMed, Web of Science, EMBASE and the Cochrane Database were specifically searched for pertinent and original articles published before May 2019. The project has been registered in PROSPERO (Registration number: CRD42019137579). RESULTS Four randomized controlled trials and six nonrandomized controlled trials with a total of 2101 patients were enrolled in this meta-analysis. The use of an external stent resulted in better performance than the use of an internal stent in terms of pancreatic fistula (grade C) (OR 0.58, P = 0.03) but did not reduce the rate of pancreatic fistula (grade B) (OR 0.99, P = 0.94) in all studies. The meta-analysis of randomized controlled trials found that the use of an external stent approached a level of significance for an increased rate of clinically relevant postoperative pancreatic fistula compared to the use of an internal stent (OR 1.40, P = 0.10) but had no significant effect on pancreatic fistula (grade B) (OR 1.34, P = 0.26) or pancreatic fistula (grade C) (OR 1.68, P = 0.62). CONCLUSION Compared with internal stents, the use of external stent might be associated with a lower rate of pancreatic fistula (grade C). More randomized clinical trials are warranted to further explore safety and efficacy of pancreatic duct external stents.

Abstract
BACKGROUND To determine the most appropriate pancreatic drainage method, by investigating differences in 12-month clinical outcomes in patients implanted with external and internal pancreatic stents as an extension to a previous study on short-term outcome. METHODS This prospective randomized controlled trial enrolled 213 patients who underwent pancreaticoduodenectomy with duct to mucosa pancreaticojejunostomy between August 2010 and January 2014 (NCT01023594). Of the 185 patients followed-up for 12 months, 97 underwent external and 88 underwent internal stenting. Their long-term clinical outcomes were compared. RESULTS Overall late complication rates were similar in the external and internal stent groups (P = 0.621). The percentage of patients with >50% atrophy of the remnant pancreatic volume after 12 months was similar in both groups (P = 0.580). Factors associated with pancreatic exocrine or endocrine function, including stool elastase level (P = 0.571) and rate of new-onset diabetes (P = 0.179), were also comparable. There were no significant between-group differences in quality of life, as evaluated by the EORTC QLQ-C30 and QLQ PAN26 questionnaires. CONCLUSION External and internal stents showed comparable long-term, as well as short-term clinical outcomes, including late complication rates, preservation of pancreatic duct diameters, pancreatic volume changes with functional derangements, and quality of life after surgery.

Abstract
BACKGROUND The postoperative pancreatic fistula rate remains approximately 10-20% even in institutions treating a high-volume of pancreatic cases. The best strategy to restore the continuity between the pancreatic remnant and the digestive tract is still in debate. DATA SOURCES Studies were identified by searching PubMed for studies published between January 1934 (when pancreaticogastrostomy was technically feasible) and December 2016. The following search terms were used: "duct-to-mucosa", "invagination", "pancreaticojejunostomy", "pancreaticogastrostomy," and "pancreaticoduodenectomy". The search was limited to English publications. RESULTS Many technical methods have been developed and optimized to restore pancreaticoenteric continuity, including pancreaticojejunostomy, pancreaticogastrostomy, and stented drainage of the pancreatic duct, among other modifications. Researchers have also attempted to decrease the postoperative pancreatic fistula after pancreaticoduodenectomy by using fibrin glue and somatostatin analogues. However, no significant decrease in postoperative pancreatic fistula has been observed in most of these studies, and only an external pancreatic duct stent has been found to decrease the leakage rate of pancreatic anastomosis after pancreaticojejunostomy. CONCLUSION Pancreatic surgeons should choose a suitable technique according to the characteristics of individual cases.

Abstract
BACKGROUND Despite a large number of studies, the ideal technique of pancreaticojejunostomy (PJ) after pancreaticoduodenectomy (PD) remains debatable. We compared the two most common techniques of PJ (duct-to-mucosa and dunking) in a randomized trial. METHODS This open-label randomized trial was done at a tertiary care center from January 2009 to October 2015. Patients with resectable periampullary tumours with a pancreatic duct diameter ≥2 mm, requiring PD were randomly assigned to one of the two techniques using computer generated random numbers. The primary outcome was postoperative pancreatic fistula (POPF) rate and secondary outcomes were frequency of other postoperative complications. RESULTS A total of 193 patients were randomized and analyzed (intention-to-treat analysis), 97 in duct-to-mucosa and 96 in dunking group. Both groups were comparable for baseline demographic and clinical profiles. The incidence of POPF in the entire study group was 23.8%. There was no statistically significant difference between the two groups (24.7% vs 22.9%, P = 0.71). Similarly, the incidence of grades B and C (clinically significant) POPF was comparable (16.5% vs 13.5%, P = 0.57). Both groups were comparable with respect to the secondary outcomes. DISCUSSION The duct-to-mucosa technique of PJ after PD is not superior to the dunking technique with respect to POPF rate. (CTRI/2010/091/000531).

Abstract
BACKGROUND Pancreatoduodenectomy (PD) is one of the most technically demanding operations challenging surgeons, and a postoperative pancreatic fistula (POPF) can complicate an otherwise uneventful postoperative (PO) course. This review examined the methods and procedures used to prevent postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD). METHODS A comprehensive systematic search of the literature was performed using PubMed (Medline), Embase, Web of science, and the Cochrane databases for studies published between January 1, 1990 and December 31, 2015. English language articles involving at least 100 patients undergoing PDs carried out in centers performing at least 10 PDs/y were screened for data regarding the Grade of any POPFs according to the definition of the International Study Group on Pancreatic Fistula (ISGPF) and the overall rate of PO mortality related to POPF. RESULTS We reviewed 7119 references through the major databases, and an additional 841 studies were identified by cross-checking the bibliographies of the full-text articles retrieved. After excluding 7379 out of 7960 studies, because they did not meet the eligibility criteria, the full texts of 581 articles were examined; 96 studies were excluded at this point, because they concerned partially or totally duplicate data that had already been reported. The remaining 485 articles were screened carefully for POPF-related mortality and POPF Grades as defined by the ISGPF. Of the 485 articles, 208 reported the POPF-related PO mortality rate and 162 the Grades (A, B, and C) of POPFs in 60,739 and 54,232 patients, respectively. The POPF-related mortality rates after pancreatojejunostomy and pancreatogastrostomy were similar but were less (0.5% vs. 1%; P = .014) when an externally draining, trans-anastomotic stent was placed intraoperatively. The incidence of the different Grades of POPF Grade was quite variable, but Grade C POPFs were associated with a PO mortality rate of 25.7% (range 0-100%). CONCLUSIONS The POPF-related mortality rate has remained at approximately 1% over the past 25 years. Only externally draining, trans-anastomotic stents decreased the POPF-related mortality rate. However, adequately designed venting drains were never tested in randomized controlled trials (RCTs).

Abstract
BACKGROUND Pancreas surgery has developed into a fairly safe procedure in terms of mortality, but is still hampered by considerable morbidity. Among the most frequent and dreaded complications are the development of a post-operative pancreatic fistula (POPF). The prediction and prevention of POPF remains an area of debate with several questions yet to be firmly addressed with solid answers. METHODS A systematic review of systematic reviews/meta-analyses and randomized trials in the English literature (PubMed/MEDLINE, Cochrane library, EMBASE) covering January 2005 to December 2015 on risk factors and preventive strategies for POPF. RESULTS A total of 49 systematic reviews and meta-analyses over the past decade discussed patient, surgeon, pancreatic disease and intraoperative related factors of POPF. Non-modifiable factors (age, BMI, comorbidity) and pathology (histotype, gland texture, duct size) that indicates surgery are associated with POPF risk. Consideration of anastomotic technique and use of somatostatin-analogs may slightly modify the risk of fistula. Sealant products appear to have no effect. Perioperative bleeding and transfusion enhance risk, but is modifiable by focus on technique and training. Drains may not prevent fistulae, but may help in early detection. Early drain-amylase may aid in detection. Predictive scores lack uniform validation, but may have a role in patient information if reliable pre-operative risk factors can be obtained. CONCLUSIONS Development of POPF occurs through several demonstrated risk factors. Anastomotic technique and use of somatostatin-analogs may slightly decrease risk. Drains may aid in early detection of leaks, but do not prevent POPF.

Abstract
Background Either enucleation or more extended resection is performed to treat patients with pancreatic neuroendocrine tumor (pNET). Aim was to analyze the postoperative complications for each operation separately. Furthermore, independent risk factors for complications and incidence of pancreatic insufficiency were analyzed. Methods Retrospective all resected patients from two academic hospitals in The Netherlands between 1992 and 2013 were included. Postoperative complications were scored by both ISGPS and Clavien–Dindo criteria. Based on tumor location, operations were compared. Independent risk factors for overall complications were identified. During long-term follow-up, pancreatic insufficiency and recurrent disease were analyzed. Results Tumor enucleation was performed in 60/205 patients (29 %), pancreatoduodenectomy in 65/205 (31 %), distal pancreatectomy in 72/205 (35 %) and central pancreatectomy in 8/205 (4 %) patients. Overall complications after tumor enucleation of the pancreatic head and pancreatoduodenectomy were comparable, 24/35 (69 %) versus 52/65 (80 %). The same was found after tumor enucleation and resection of the pancreatic tail (36 vs.58 %). Number of re-interventions and readmissions were comparable between all operations. After pancreatoduodenectomy, 33/65 patients had lymph node metastasis and in patients with tumor size ≤2 cm, 55 % had lymph node metastasis. Tumor in the head and BMI ≥25 kg/m2 were independent risk factors for complications after enucleation. During follow-up, incidence of exocrine and endocrine insufficiency was significant higher after pancreatoduodenectomy (resp. 55 and 19 %) compared to the tumor enucleation and distal pancreatectomy(resp. 5 and 7 % vs.8 and 13 %). After tumor enucleation 19 % developed recurrent disease. Conclusion Since the complication rate, need for re-interventions and readmissions were comparable for all resections, tumor enucleation may be regarded as high risk. Appropriate operation should be based on tumor size, location, and functional status of the pNET.

Abstract
BACKGROUND Enucleation of pancreatic neuroendocrine tumours (pNETs) via robotic surgery has rarely been described. This study sought to assess the safety and efficiency of robotic surgery for the enucleation of small pNETs. METHODS A comparison was conducted of enucleation of pNETs smaller than 2 cm by robotic or open surgery between January 2000 and May 2015. Propensity score matching was used to balance sex, age, BMI, tumour location and tumour diameter. Pathological results, safety-related outcomes (postoperative pancreatic fistula (POPF) rate, estimated blood loss, and short-term mortality and morbidity) and efficiency-related outcomes (duration of surgery and postoperative length of hospital stay) were compared between the groups. RESULTS A cohort of 120 patients with pNET were enrolled in the study (1 : 1 matched for open or robotic surgery, 60 per group). Ninety-three patients (77·5 per cent) had a grade 1 tumour and 114 (95·0 per cent) had an insulinoma. Robotic surgery had a conversion rate of 5 per cent (3 of 60), and was not associated with an increased POPF rate (10 per cent versus 17 per cent after open surgery; P = 0·283) or grade III-V surgical complications according to the Dindo-Clavien classification (3 versus 10 per cent respectively; P = 0·272). Estimated blood loss was reduced with the robotic approach (32·5 versus 80·0 ml in the open group; P = 0·008), as was duration of surgery (117 versus 150 min; P < 0·001). Length of hospital stay after surgery was similar in the two groups (12·0 versus 13·5 days respectively; P = 0·071). CONCLUSION Robotic surgery for enucleation of pNETs smaller than 2 cm did not increase POPF or major complication rates, and reduced the duration of surgery and estimated blood loss, compared with open surgery.

Abstract
Pancreato-duodenectomy (PD) is the treatment of choice for periampullary tumors, and currently, indications have been extended to benign disease, including symptomatic chronic pancreatitis, paraduodenal pancreatitis, and benign periampullary tumors that are not amenable to conservative surgery. In spite of a significant decrease in mortality in high volume centers over the last three decades (from>20% in the 1980s to<5% today), morbidity remains high, ranging from 30% to 50%. The most common complications are related to the pancreatic remnant, such as postoperative pancreatic fistula, anastomotic dehiscence, abscess, and hemorrhage, and are among the highest of all surgical complications following intra-abdominal gastro-intestinal anastomoses. Moreover, pancreatico-enteric anastomotic breakdown remains a life-threatening complication. For these reasons, the management of the pancreatic stump following resection is still one of the most hotly debated issues in digestive surgery; more than 80 different methods of pancreatico-enteric reconstructions having been described, and no gold standard has yet been defined. In this review, we analyzed the current trends in the surgical management of the pancreatic remnant after PD.

Abstract
BACKGROUND There is no consensus on the best method of preventing postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD). This multicentre, parallel group, randomized equivalence trial investigated the effect of two ways of pancreatic stenting after PD on the rate of POPF. METHODS Patients undergoing elective PD or pylorus-preserving PD with duct-to-mucosa pancreaticojejunostomy were enrolled from four tertiary referral hospitals. Randomization was stratified according to surgeon with a 1 : 1 allocation ratio to avoid any related technical factors. The primary endpoint was clinically relevant POPF rate. Secondary endpoints were nutritional index, remnant pancreatic volume, long-term complications and quality of life 2 years after PD. RESULTS A total of 328 patients were randomized to the external (164 patients) or internal (164) stent group between August 2010 and January 2014. The rates of clinically relevant POPF were 24·4 per cent in the external and 18·9 per cent in the internal stent group (risk difference 5·5 per cent). As the 90 per cent confidence interval (-2·0 to 13·0 per cent) did not fall within the predefined equivalence limits (-10 to 10 per cent), the clinically relevant POPF rates in the two groups were not equivalent. Similar results were observed for patients with soft pancreatic texture and high fistula risk score. Other postoperative outcomes were comparable between the two groups. Five stent-related complications occurred in the external stent group. Multivariable analysis revealed that soft pancreatic texture, non-pancreatic disease and high body mass index (23·3 kg/m2 or above) predicted clinically relevant POPF. CONCLUSION External stenting after PD was associated with a higher rate of clinically relevant POPF than internal stenting. Registration number: NCT01023594 (https://www.clinicaltrials.gov).

Abstract
BACKGROUND Two types of pancreatic duct stents are used to improve postoperative outcomes of pancreatic anastomosis. The aim of this meta-analysis was to evaluate and compare the postoperative outcomes of patients with internal or external stenting during pancreaticoduodenectomy (PD). METHODS We searched PubMed, EMBASE, the Cochrane Library and Web of Science databases until the end of December, 2014. Studies comparing outcomes of external vs. internal stent placement in PD were eligible for inclusion. Included literature was extracted and assessed by two independent reviewers. RESULTS Seven articles were identified for inclusion: three randomized controlled trials (RCTs) and four observational clinical studies (OCS). The meta-analyses revealed that use of external stents had advantage on reducing the incidences of pancreatic fistula (PF) in total [odds ratio (OR) =0.69; 95% confidence interval (CI), 0.48-0.99; P=0.04], PF in soft pancreas (OR =0.30; 95% CI, 0.16-0.56; P=0.0002) and delayed gastric emptying (DGE) (OR =0.58; 95% CI, 0.38-0.89; P=0.01) compared with internal stents. There were no significant differences in other postoperative outcomes between two stenting methods, including postoperative morbidity (OR =0.93; 95% CI, 0.39-2.23; P=0.88), overall mortality (OR =0.70; 95% CI, 0.22-2.25; P=0.55), and intra-abdominal collections (OR =0.67; 95% CI, 0.26-1.71; P=0.40). CONCLUSIONS Based upon this meta-analysis, the use of external pancreatic stents might have potential benefit in reducing the incidence of PF and DGE. Due to the limited number of original studies, more RCTs are needed to further support our result and clarify the issue.

Abstract
Surgical resection remains the only potentially curative therapy for pancreatic cancer, despite a high rate of systemic recurrence. Because of local invasion or distant spread, a minority of patients presenting with pancreatic cancer are candidates for surgery. Although perioperative mortality is low in high-volume settings, pancreatic surgery remains associated with considerable morbidity. Minimally invasive and robotic surgical techniques are increasingly used for pancreatic resection, although not always applicable to all patients. Strategies to extend the benefits of margin-negative surgical resection to more patients include surgery with vascular resection and reconstruction for locally invasive tumors, and resection after neoadjuvant therapy.

Abstract
Pancreatic cancer surgery represents a challenge for surgeons due to its technical complexity, the potential complications that may appear, and ultimately because of its poor survival. The aim of this article is to summarize the scientific evidence regarding the surgical treatment of pancreatic cancer in order to help surgeons in the decision making process in the management of these patients .Here we will review such fundamental issues as the need for a biopsy before surgery, the type of pancreatic anastomosis leading to better results, and the need for placement of drains after pancreatic surgery will be discussed.

Abstract
BACKGROUND Resection for pancreatic neuroendocrine tumours (PNET) is suggested to be associated with an increased risk of a post-operative pancreatic fistula (POPF). The aim of this study was to describe morbidity after resections for PNET, focusing on POPF. Outcomes were compared with resections for other lesions. METHODS Patients undergoing an elective pancreatic resection during a 12-year period were retrospectively analysed. Morbidity was defined according to the International Study Group of Pancreatic Surgery (ISGPS) definitions. RESULTS Eighty-eight out of 832 patients (10.6%) underwent a resection for PNET. Atypical pancreatic resections (enucleation and central pancreatectomy) and distal pancreatectomies were more frequently performed for PNET. The POPF rate was 22.7% in patients operated for PNET compared with 17.2% in other patients (P = 0.200). In univariate analysis, body mass index (BMI), pancreatic duct diameter, somatostatin analogue administration, type of resection and type of pathology were associated with a POPF. In multivariate analysis, BMI, a pancreatic duct diameter <3 mm and central pancreatectomy remained independent risk factors [odds ratio (OR) 1.93, 95% confidence interval (CI) 1.22-3.07 and OR 3.04, 95% CI 1.05-8.82, respectively]. CONCLUSIONS High rates of POPF were found in patients operated for PNET. However, this was mainly owing to the fact that atypical resections, known to be associated with a higher fistula rate, were performed more frequently in these patients.

Evaluation of a recently described risk classification scheme for pancreatic fistulae development after pancreaticoduodenectomy without routine post-operative drainage. HPB (Oxford) 2014; 16:987-93.

Abstract
BACKGROUND Post-operative pancreatic fistula (POPF) formation occurs frequently after a pancreaticoduodenectomy (PD). Recently, a 10-point Fistula Risk Score (FRS) evaluating the likelihood of clinically relevant POPF (CR-POPF) development has been described and validated. This scheme has yet to be evaluated in PD patients managed without intra-operative drain placement. METHODS Among patients undergoing PD at an academic centre since 2003, a retrospective analysis calculating FRS and its correlation with CR-POPF development was evaluated by logistic regression. Secondary analysis examined presentation and management of CR-POPF in undrained PD patients. RESULTS FRS was calculated for 265 patients; 97.7% were managed without operative drains. The overall incidence of CR-POPF was 7.9%. Logistic regression revealed a 1.6-fold increase in CR-POPF risk per 1-point increase in FRS [95% confidence interval (CI) 1.2-2.0]. The negative predictive value in patients with FRS <3 was 100%, whereas the positive predictive value of FRS >6 was 16.7%. The median time to CR-POPF diagnosis was 18 days [interquartile range (IQR) 13-23]; 70.0% required readmission and 10.0% required a laparotomy. CONCLUSIONS Among patients without operative drainage, CR-POPF often has delayed presentations but most are managed non-operatively. The predictive value of high-risk FRS appears limited; conversely, a low-risk FRS accurately predicts the absence of CR-POPF and seems an appropriate metric for guiding care.

Abstract
Increased awareness of periampullary & pancreatic head cancers, and the accompanying improved outcomes following pancreatoduodenectomy (PD), has possibly led to an increase in patients seeking treatment for the same. While there has definitely been a reduction in morbidity rates following PD in the last few decades, this decline has not mirrored the drastic fall in mortality. Amongst the foremost in the factors responsible for this reduction in mortality is the standardization of surgical technique and development of dedicated teams to manage all aspects of this demanding procedure. This review intends to provide the reader with an overview of major complications following this major surgery and measures to prevent them based on the authors' experience.

Abstract
PURPOSE OF REVIEW To summarize published research on pancreatic surgery over the past year. RECENT FINDINGS A number of studies aiming to reduce the costs associated with pancreatic surgery were reported. Retrospective analyses confirmed previous findings that neither the routine use of pancreatic duct stents decreases the rate of fistula formation nor does placement of a drain at the time of surgery change the morbidity in patients who develop one. Minimally invasive approaches, both laparoscopic and robot-assisted, are being performed more frequently to remove pancreatic cancers. A randomized trial confirmed that reinforcement of stapled closure during distal pancreatectomy reduces the rate of fistula formation. Controversy remains over whether small pancreatic neuroendocrine tumors need to be surgically resected or can be treated nonoperatively. Patients with chronic pancreatitis should be screened thoroughly before being offered surgical treatment; two studies reported preoperative factors that can be used to identify those most likely to experience pain relief. SUMMARY Studies published on pancreatic surgery last year focused on a wide-range of topics. The morbidity and mortality of patients undergoing pancreatic surgery continues to improve, and we anticipate that incorporation of these new findings will lead to even better outcomes.
