Abstract
BACKGROUND The failure of pancreatic anastomosis after the proximal pancreaticoduodenectomy (PD) and the failure of pancreatic stump after the distal pancreatectomy with a resulting postoperative pancreatic fistula remain the most feared complications after pancreatic resection. Surgeons have been trying to find a reliable reconstructive technique of pancreatic anastomosis for decades. METHODS A literature search was performed to January 2020. Studies giving a detailed description of the pancreatic anastomosis after open PD and pancreatic stump closure techniques after the distal pancreatectomy were included. The aim of this study was review reported data derived from meta-analyses concerning the incidence of POPF according to the International Study Group of Pancreatic Surgery. A comparison of various surgical techniques and their impact on POPF incidence was made. RESULTS In the group of clinically relevant POPF (CR- POPF), a well established difference between the patients undergoing POPF-associated interventional drainage or reoperation was observed. Meta-analyses showed that the patients with CR- POPF were statistically more likely to have a small duct size, soft gland texture, particular pancreatic neoplasms and an excessive intraoperative blood loss. CONCLUSION Grade C POPF following PD, although uncommon, occurs with a defined incidence and is associated with a substantial morbidity, prolonged hospitalization, delayed recovery and a significant mortality. According to the results of various meta-analyses, pancreatogastrostomy and pancreatojejunostomy seemed to be comparable anastomotic techniques following PD (Ref. 54).

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
OBJECTIVE To analyze the role of contrast-enhanced computed tomography in evaluation of pancreatic stump volume for prediction of significant pancreatic fistula. MATERIAL AND METHODS A retrospective analysis enrolled 99 patients. Patients were divided into 2 groups depending on the course of postoperative period and development of clinically significant pancreatic fistula. The first group included 24 patients (25%) with clinically significant postoperative pancreatic fistula. The second group included 75 patients (75%) without postoperative complications. Pancreatic structure, pancreatic parenchyma thickness (mm), pancreatic duct diameter (mm) and volume of pancreatic stump (cm3) were preoperatively analyzed considering contrast-enhanced computed tomography data. RESULTS The risk of postoperative pancreatic fistula is 10 times higher in case of soft structure of the pancreas, 1,7 times higher in decrease of pancreatic duct diameter, 9,3 times higher in increased volume of residual pancreatic parenchyma, 8.6 times higher in increase of pancreatic parenchyma thickness. CONCLUSION Contrast-enhanced computed tomography is valuable for preoperative evaluation of the volume of residual pancreatic parenchyma and identification of patients with high risk of postoperative pancreatic fistula.

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 The association between bacterial infection and clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreatoduodenectomy (PD) has not been fully elucidated. METHODS Microbiological data for intraoperative bile culture (BC) and drain culture on postoperative day 4 (DC) were collected. The study population was classified into the following three groups: P1 (positive BC and DC), P2 (positive BC and negative DC), and N (negative BC). A total of 209 patients (P1: 38, P2: 72, and N: 99) who underwent PD between May 2013 and May 2018 met the inclusion criteria of the study. RESULTS The rate of CR-POPF was significantly higher in the P1 group (34.2%) than in the P2 (12.5%; P = .007) and N groups (14.1%; P = .008). Between P1 and P2 groups, a significant difference was observed in the proportion of Enterococcus faecalis grown in BC (42.1% vs 4.2%; P < .001). Multivariable logistic regression analysis showed that the presence of E faecalis in bile was independently associated with CR-POPF. CONCLUSIONS The detection of both bile and postoperative abdominal fluid infections can be more accurate in predicting CR-POPF. Furthermore, the presence of E faecalis in bile may serve as a novel surrogate marker for CR-POPF.

Abstract
Objective Postpancreatectomy hemorrhage is a life-threatening complication. Hemorrhage occurring >24 hours after the index operation is defined as late hemorrhage. This study was performed to analyze the therapeutic management and prognostic factors of late hemorrhage after pancreatectomy. Methods We identified 87 patients with late hemorrhage among 2031 patients who underwent pancreatic surgery from January 2013 to December 2017. The patients’ demographic characteristics, perioperative treatment, hemorrhage details, and prognosis were retrospectively analyzed. Results Of the 87 patients, 53 were men. Bleeding occurred at a mean of 8.9 ± 6.0 days postoperatively. Extraluminal and intraluminal hemorrhage occurred in 58 and 29 patients, respectively. The primary intervention was successful in 66 patients, and 16 patients required a secondary intervention. The primary and total recovery rates were 72.4% and 89.7%, respectively. Of the 87 patients, 9 died. Male sex, hemorrhage on a later postoperative day, a significantly decreased hemoglobin level, and pancreatic fistula showed statistical significance as possible risk factors for mortality. Conclusions Male sex, hemorrhage on a later postoperative day, a significantly decreased hemoglobin level, and pancreatic fistula are possible risk factors for mortality in patients with late hemorrhage after pancreatectomy. Hemorrhage is a dynamic process, and a secondary intervention may be necessary.

Abstract
INTRODUCTION Pancreaticopleural fistula (PPF) is a rare but serious complication of pancreatic disorders. As the clinical presentations of PPF are often deceptive, it can cause a delay in the timely diagnosis and proper treatment. PPF is extremely uncommon in pediatric patients, and diagnostic and management strategies for PPF among pediatric patients are scanty. PATIENT CONCERNS A 12-year-old girl presented with cough and dyspnea owing to massive right-side pleural effusion confirmed by Chest X-ray. Biochemical examination of pleural effusion revealed a significant elevation of amylase level. Imaging modalities showed dilated pancreatic duct and fistulous tract connecting pancreatic duct and right thorax. DIAGNOSIS Chronic pancreatitis with PPF was diagnosed. INTERVENTIONS Medical therapy was initially attempted for 2 weeks. Endoscopic therapy with naso-pancreatic drainage tube placement was then performed without any complications after failed medical therapy. OUTCOMES The patient has remained healthy and symptom-free during 2 years of follow-up. CONCLUSION When pediatric patients presented with recurrent pleural effusion with unknown etiology, PPF should be taken into consideration. Pleural effusion amylase level is the most important laboratory test and magnetic resonance cholangiopancreatography is recommended to visualize the fistula. Optimal management of PPF should be based on pancreatic duct morphology.

Abstract
The modified Blumgart method for pancreaticojejunostomy has been shown to reduce the rate of postoperative pancreatic fistula (POPF) in open surgery. We describe a modified Blumgart method using LAPRA-TY suture clips to facilitate laparoscopic pancreaticojejunostomy.We prepared a double-armed 4-0 nonabsorbable monofilament, which was ligated using the LAPRA-TY clip at the tail end, 12-cm in length. Next, the U-suture was placed through the pancreatic stump and the seromuscular layer of the jejunum. We performed duct-to-mucosa suturing with a 5-0 absorbable monofilament. After completing the duct-to-mucosa suturing, as a final step we placed the sutures through the seromuscular layer of the jejunum on the ventral side and tightly secured the thread with the LAPRA-TY clips. We performed laparoscopic Blumgart pancreaticojejunostomy during pancreaticoduodenectomy in 39 patients. We compared the surgical outcomes of 19 patients who underwent Blumgart pancreaticojejunostomy using the LAPRA-TY clips (LAPRA-TY group) with 20 patients undergoing surgery not using the LAPRA-TY clips (conventional group).The rate of clinically relevant postoperative pancreatic fistula in the LAPRA-TY group was 21.1%, which did not differ significantly from the rate of the conventional group. However, the mean time of pancreaticojejunostomy in the LAPRA-TY group was 56.2 min (range, 39-79 min), which was significantly shorter than that of the conventional group (69.7 min; range, 53-105 min, P < .001).Although the modified Blumgart pancreaticojejunostomy using LAPRA-TY suture clips did not improve the pancreatic fistula rate, it allowed for shorter operative times. Thus, this procedure lends itself to positive surgical and patient outcomes.

Abstract
The main mechanism of hyaluronidase 1(HYAL-1) in the development of postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD) was unknown. In this study, a comprehensive inventory of pre-, intra-, and postoperative clinical and biological data of two cohorts (62 pancreatic cancer [PCa] and 111 pancreatic ductal adenocarcinoma [PDAC]) which could induce POPF were retrospectively analyzed. Then, a total of 7644 genes correlated with HYAL-1 was predicted in PDAC tissues and the enriched pathway, kinase targets and biological process of those correlated genes were evaluated. Finally, a mouse pancreatic fistula (PF) model was first built and in vitro studies were performed to investigate the effects of HYAL-1 on PF progression. Our data indicated that preoperative serum HYAL-1 level, pancreatic fibrosis score, and pancreatic duct size were valuable factors for detecting POPF of Grade B and C. The serum HYAL-1 level of 2.07 mg/ml and pancreatic fibrosis score of 2.5 were proposed as the cutoff values for indicating POPF. The bioinformatic analysis and in vitro and in vivo studies demonstrated that HYAL-1 facilitates pancreatic acinar cell autophagy via the dephosphorylation of adenosine 5'-monophosphate-activated protein kinase (AMPK) and signal transducers and activators of transcription 3 (STAT3) signaling pathways, which exacerbate pancreatic secretion and inflammation. In summary, the preoperative serum HYAL-1 was a significant predictor for POPF in patients who underwent PD. Tumor-induced HYAL-1 is one of core risk in accelerating PF and then promoting pancreatic secretion and acute inflammation response through the AMPK and STAT3-induced autophagy.

Abstract
Background: This retrospective comparative case series study aims to analyze the pancreatic fistula rates of internal and external stenting of the pancreatojejunostomy (PJ) anastomosis in patients who underwent pancreatoduodenectomy (PD) for periampullary tumors.Methods: Ninety-eight patients with periampullary tumors who were operated between 2010 and 2017 were enrolled in this study. A classic open PD with Roux-en-Y PJ reconstruction was performed in all cases.Results: The PJ anastomosis of 53 patients (54%) were stented internally whereas in 45 patients (46%) external stenting was preferred. Pancreatic fistula was observed in 29 patients (29.6%). Internal stenting and soft pancreatic tissue were found to be related to higher pancreatic fistula rates with odds ratios of 3.27 (p = .024) and 3.4 (p = .017), respectively. When only grade B and grade C fistulas were taken into account, the type of stenting has lost its significance but the texture of the remnant pancreas was still associated with 'clinically important' pancreatic fistula.Conclusions: We concluded that the external stenting of the PJ anastomosis may be considered as an effective approach for reducing postoperative pancreatic leaks in PD-planned patients for periampullary tumors. Although our study was retrospectively designed, we used standard charts to gather patient data and compared two stenting methods among homogeneous patient groups.

Abstract
OBJECTIVE Identifying the opportunity of objective prognosis of pancreatic fistula emergence after pancreatoduodenectomy. MATERIAL AND METHODS In the department of abdominal surgery in 2016-2019, 177 pancreatoduodenectomies for pancreatobiliary tumors were performed. 4 risk factors were identified: type of tumor, preoperative CT with an accumulation coefficient in the pancreas of more than 1, soft pancreas, the number of functioning acinar structures identified during intraoperative histological examination. Statistical data processing and predictive modeling were performed using a binary logistic regression model. RESULTS Clinically significant pancreatic fistula was developed in 47 (26,6%) patients. Risk indicators for the occurrence of pancreatic fistula depending on the presence or absence of risk factors were obtained. Groups of patients were identified that require various preventive and therapeutic measures aimed to treat postoperative pancreatitis and its consequences. CONCLUSION Predicting the pancreatic fistula emergence allows to take timely preventive and therapeutic measures, both minimal and aggressive (early extracorporeal detoxification, pancreatectomy), which may lead to complications. Well-reasoned pancreatectomy and extracorporeal detoxification is a surgeon's defense in an insured case or legal conflict.

Abstract
Laparoscopic adrenalectomy is currently considered the gold standard for adrenal tumors up to 6 cm, and although with far less morbidity than the open alternative, when it comes to its complications we should not look away. The case concerns a 51-year old obese male that underwent left laparoscopic adrenalectomy for incidentaloma and developed pancreatic tail fistula. Without an evident pancreatic lesion during surgery and an uneventful early postoperative course the patient was discharged only to return 4 days later with respiratory symptoms and mild abdominal discomfort in the left upper quadrant. The CT scan diagnosed a left subphrenic fluid collection and left basal pneumonia, thus the patient underwent laparoscopic reintervention for drainage of the pancreatic fluid collection and received conventional antibiotherapy for pneumonia. The patient was discharged in good condition with the drainage tube in situ. The drainage tube was extracted 14 days later.

Abstract
Objectives: A postoperative pancreatic fistula (POPF) is defined as a threefold increase in the amylase concentration in abdominal drains on or after the third postoperative day (POD). However, additional lipase fluid analysis is widely used despite lacking evidence. In this study, drain amylase and lipase levels were compared regarding their value in detecting POPF. Methods: We conducted a retrospective study including all patients who underwent pancreatic resections at our center between 2005 and 2016. Drain fluid analysis was performed from day 2 to 5. Results: 990 patients were included in the analysis. Overall, 333 (34%) patients developed a POPF. The median amylase and lipase concentrations at POD 3 in cases with POPF were 11.55 µmol/(s·L) (≈13 ×-fold increase) and 39 µmol/(s·L) (≈39 ×-fold increase), respectively. Seven patients with subsequent POPF (2%) were missed with amylase analysis on POD 3, but detected using 3-fold lipase analysis. The false-positive rate of lipase was 51/424 = 12%. A cutoff lipase value at POD 3 of > 4.88 yielded a specificity of 94% and a sensitivity of 89% for development of a POPF. Increased body mass index turned out as risk factor for the development of POPF in a multivariable model. Conclusions: Threefold-elevated lipase concentration may be used as an indicator of a POPF. However, the additional detection of POPF using simultaneous lipase analysis is marginal. Therefore, assessment of lipase concentration does not provide added clinical value and only results in extra costs.

Abstract
Postoperative pancreatic fistula (POPF) is the most common and critical complication after pancreatic body and tail resection. How to effectively reduce the occurrence of pancreatic fistula and conduct timely treatment thereafter is an urgent clinical issue to be solved. Recent research standardized the definition of pancreatic fistula and stressed the correlation between POPF classification and patient prognosis. According to the literature, identification of the risk factors for pancreatic fistula contributed to lowering the rate of the complication. Appropriate management of the pancreatic stump and perioperative treatment are of great significance to reduce the rate of POPF in clinical practice. After the occurrence of POPF, the treatment of choice should be determined according to the classification of the pancreatic fistula. However, despite the progress and promising treatment approaches, POPF remains to be a clinical issue that warrants further studies in the future.

Abstract
BACKGROUND/AIM In order to overcome postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP), we have developed a new simple technique-Clip on Staple method. PATIENTS AND METHODS In Clip on Staple method, pancreatic parenchyma was divided using a stapling device with a stepped-height staple design to make linear compression line, and thereafter, the full length of the staple line was reinforced by multiple clips. Clinical outcomes were retrospectively compared between Clip on Staple group (n=23) and Non-Clip group (n=38). RESULTS The incidence of clinically relevant POPF (CR-POPF) was significantly lower in the Clip on Staple group than in the Non-Clip group (4.3 and 36.8%, p=0.005). Multivariate logistic regression analysis revealed that only Clip on Staple method was an independent predictive factor of a decrease in the occurrence of CR-POPF. CONCLUSION The Clip on Staple method, a simple and easily applicable technique even in laparoscopic surgery, significantly reduced the occurrence of CR-POPF among patients undergoing DP.

Abstract
BACKGROUND Robotic surgical systems have advantages over laparoscopic surgery. The object of this study was to assess patients' postoperative outcomes after robotic distal gastrectomy (RDG) compared to laparoscopic distal gastrectomy (LDG). PATIENTS AND METHODS We retrospectively evaluated 21 and 119 patients who underwent RDG and LDG, respectively, for stage I gastric cancer. Short-term outcomes were compared including drain amylase levels and quality of life using a post-gastrectomy syndrome questionnaire. RESULTS No patients experienced pancreatic fistula or anastomosis-related complications following RDG. The rate of overall complications tended to be lower in patients undergoing RDG. In addition to drain amylase level, inflammatory findings were lower after RDG than LDG. Patients undergoing RDG experienced a better quality of life and less dissatisfaction in daily life. CONCLUSION RDG is feasible and produced highly-satisfactory results for early gastric cancer. We believe that the effective use of robotic surgery will increase safety and precision in minimally invasive surgery.

Abstract
BACKGROUND The use of octreotide prophylaxis following pancreatic surgery is controversial. We aimed to evaluate the effectiveness of octreotide for the prevention of postoperative complications after pancreatic surgery through this systematic review and meta-analysis. METHODS Literature databases (including the MEDLINE, EMBASE, and Cochrane databases) were searched systematically for relevant articles. Only randomized controlled trials (RCTs) were eligible for inclusion in our research. We extracted the basic information regarding the patients, intervention procedures, and all complications after pancreatic surgery and then performed the meta-analysis. RESULTS Thirteen RCTs involving 2006 patients were identified. There were no differences between the octreotide group and the placebo group with regard to pancreatic fistulas (PFs) (relative risk [RR] = 0.79, 95% confidence interval [CI] = 0.62-0.99, P = .05), clinically significant PFs (RR = 1.01, 95% CI = 0.68-1.50, P = .95), mortality (RR = 1.21, 95% CI = 0.78-1.88, P = .40), biliary leakage (RR 0.84, 95% CI = 0.39-1.82, P = .66), delayed gastric emptying (RR = 0.83, 95% CI = 0.54-1.27, P = .39), abdominal infection (RR = 1.00, 95% CI = 0.66-1.52, P = 1.00), bleeding (RR = 1.16, 95% CI = 0.78-1.72, P = .46), pulmonary complications (RR = 0.73, 95% CI = 0.45-1.18, P = .20), overall complications (RR = 0.80, 95% CI = 0.64-1.01, P = .06), and reoperation rates (RR = 1.18, 95% CI = 0.77-1.81, P = .45). In the high-risk group, octreotide was no more effective at reducing PF formation than placebo (RR = 0.81, 95% CI = 0.67-1.00, P = .05). In addition, octreotide had no influence on the incidence of PF (RR = 0.38, 95% CI = 0.14-1.05, P = .06) after distal pancreatic resection and local pancreatic resection. CONCLUSION The present best evidence suggests that prophylactic use of octreotide has no effect on reducing complications after pancreatic resection.

Abstract
BACKGROUND AND AIMS Routine drainage after pancreatoduodenectomy is a controversial issue. In this article, we present and discuss the current evidence on abdominal drains in pancreatic surgery. MATERIAL AND METHODS Review of the pertinent English-language literature. RESULTS There is a growing body of evidence showing a lack of benefit of prophylactic drainage after pancreatoduodenectomy. Randomized trials have reported similar outcomes with or without routine drains. If drains were used, early removal was found to be superior to late removal in patients with a low risk of postoperative pancreatic fistula. Consequently, criteria for early drain removal have been developed based on the measurement of drain amylase levels. On the contrary, there exists a subgroup of patients where drains may have a role. In patients with high risk of pancreatic fistula formation, such as those having a soft pancreatic texture, small pancreatic duct and high body mass index, the placement of drains may give sentinel information about future clinical deterioration. The drain may thus help reduce failure-to-rescue rates. CONCLUSION Despite much research, there are many unanswered questions regarding drains in pancreatic surgery. It is evident that routine drainage should be abandoned for a more selective strategy. Furthermore, what is needed is a postoperative warning score that early on can identify patients at risk of a pancreatic fistula, without the routine placement of drains.

Abstract
BACKGROUND AND OBJECTIVES Pancreaticoduodenectomy (PD) remains a morbid surgery. Preoperative biliary drainage (PBD) is often necessary before surgery but is associated with biliary contamination. We compared the postoperative complications of patients undergoing PBD who received the usual prophylactic antibiotics (PAs) or systematic antibiotherapy (ABT). METHODS All patients who underwent surgery between 2008 and 2017 were included. Systematic perioperative ABT with piperacillin + tazobactam (ABT group) was implemented in 2014 as the standard of care for PBD. Patients treated in the period before such implementation, during which standard cefazolin was given, served as the controls (PAs group). The primary outcomes were postoperative complications. RESULTS We included 122 patients with PBD who underwent surgery. There were no demographic differences between the two groups. Perioperative ABT was associated with a reduction in deep abdominal abscesses (36% vs 10%, P = .0008), respiratory tract infections (15% vs 3%; P = .02), bacteremia (41% vs 6%; P < .0001), and a shorter length of hospital stay (17 [13-27] vs 13 [10-14] days; P < .0001). ABT was a protective factor against the development of deep abdominal abscesses (odds ratio [OR] = 0.16; P = .001) whereas smoking (OR = 3.9) and pancreatic fistula (OR = 19.1) were risk factors. CONCLUSION Systematic perioperative ABT in patients undergoing PD preceded by PBD may reduce deep surgical infections and the length of hospital stay.

Abstract
BACKGROUND AND OBJECTIVES Delayed gastric emptying (DGE) occurs commonly following pancreaticoduodenectomy (PD), but the rate of DGE in the absence of other intra-abdominal complications is poorly understood. The objectives of this study were to define the incidence of DGE and identify risk factors for DGE in patients without pancreatic fistula or other intra-abdominal infections. METHODS Retrospective cohort study utilizing the American College of Surgeons National Surgical Quality Improvement Program pancreatectomy variables to identify patients with DGE following PD without evidence of fistula or intra-abdominal infection. Multivariable models were developed to assess preoperative, intraoperative, and technical factors associated with DGE. RESULTS The rate of DGE was 11.7% in 10502 cases without pancreatic fistula or intra-abdominal infection. Patients were more likely to develop DGE if age ≥75 (odds ratio [OR], 1.22; P = 0.003), male (OR, 1.29; P < 0.001), underwent pylorus-sparing PD (OR, 1.27; P = 0.004), or had a prolonged operative time (OR, 1.38 if greater than seven vs less than 5 hours; P = 0.005). Factors not associated with DGE included BMI, pathologic indication, and surgical approach. CONCLUSION The incidence of DGE after PD is notable even in patients without other abdominal complications. Identification of patients at increased risk for DGE may aid patient counseling as well as decisions regarding surgical technique, enteral feeding access, and enhanced-recovery pathways.

Abstract
BACKGROUND Pancreatic fistula remains common, with limited ability to risk stratify patients preoperatively. The objective of this study was to identify risk factors for clinically-relevant postoperative pancreatic fistula (CR-POPF) that are routinely available in the preoperative setting. METHODS Preoperatively available variables for all pancreaticoduodenectomies from 2014-2017 were examined using a national clinical registry. The cohort was separated into risk factor identification and internal validation subgroups. RESULTS Among 15 033 pancreaticoduodenectomies, the CR-POPF rate was 16.7%. CR-POPF was more likely in patients that were male (odds ratio [OR], 1.51), obese (body mass index [BMI] > 30, OR, 1.97), had minimal preoperative weight loss (OR, 1.25), had a nondilated pancreatic duct (OR, 1.81), did not have diabetes, (OR, 1.80), did not receive neoadjuvant therapy (OR, 1.78), had no evidence of biliary obstruction (OR, 1.18), or had nonadenocarcinoma pathology (OR, 1.96; all P < 0.01). Patients with three or fewer risk factors had a CR-POPF rate of 7.1%, while those with six or more risk factors had a CR-POPF rate of 26.3% (P < 0.001). CONCLUSION Preoperative CR-POPF risk evaluation could be a useful tool in patient counseling and surgical planning, and risk may allow for more well-informed decisions regarding perioperative management, including enhanced recovery protocols and use of somatostatin analogs.

Abstract
Context Pancreatic fistula has forever been a dreaded complication after pancreatic anastomosis (PA). We present a retrospective analysis of 10 years of experience with the Modified Heidelberg technique (MHT) that has been recently described. Aim The aim of the study is to establish postoperative pancreatic fistula (POPF) rates after MHT. Settings and Design This is a retrospective observational study carried out at a tertiary cancer center in South India in the Department of Surgical Oncology. Subjects and Methods Two hundred and eight consecutive patients who underwent pancreaticoduodenectomy (PD) and PA with MHT for a variety of proximal pancreatic lesions from January 2008 to February 2018 were included in this study. The incidence of POPF was recorded by the International Study Group on Pancreatic Fistula 2005 and 2016 definitions. Statistical Analysis Used Epidemiological and clinical data are expressed in ratios and percentage and presented in table format. Results Between January 2008 and March 2016, 186 patients underwent PD, and MHT was used for PA. Five (2.7%) patients developed Grade A POPF whereas Grades B and C were seen in three (1.6%) patients each with one death. Between April 2016 and February 2018, 22 patients underwent PD. Two patients (9%) had biochemical leak whereas none of them developed clinically relevant POPF. No deaths were recorded in this period. Overall, Grade B and Grade C POPF rates were 1.4% each, whereas 30-day mortality was 0.4%. Conclusions Results of this study indicate that MHT is a safe, reliable, easy to learn, and adopt technique of pancreatic reconstruction after PD.

Abstract
BACKGROUND AND AIMS There is no consensus regarding the routine placement of intra-abdominal drains after pancreaticoduodenectomy. We aim to determine the effects of intraperitoneal drain placement during pancreaticoduodenectomy on 30-day postoperative morbidity and mortality. METHODS Patients who underwent pancreaticoduodenectomy for pancreatic tumors were identified from the 2014-2015 American College of Surgeons-National Surgical Quality Improvement Program Database. Univariate and multivariate analyses adjusting for known prognostic variables were performed. A subgroup analysis was performed based on the risk for development of postoperative pancreatic leak determined by the pancreatic duct caliber, parenchymal texture, and body mass index. RESULTS A total of 6858 patients with pancreatic tumors who underwent pancreaticoduodenectomy were identified in the 2014-2015 American College of Surgeons-National Surgical Quality Improvement Program Database dataset. In all, 87.4% of patients had intraperitoneal drains placed. A 30-day mortality rate was higher in the no-drain group (2.9% vs. 1.7%, P = 0.003). Patients in the drain group had a higher incidence of overall morbidity (49.5% vs. 41.2%, P = 0.0008), delayed gastric emptying (18.1% vs. 13.7%, P = 0.004), pancreatic fistulae (19.4% vs. 9.9%, P ⩽ 0.0001), and prolonged length of hospital stay over 10 days (43.7% vs. 34.9%, P < 0.0001). Subgroup analysis based on risk categories revealed a higher 30-day mortality rate in the no-drain group among patients with high-risk features (3.1% vs. 1.6%, P = 0.02). Delayed gastric emptying and pancreatic fistula development remained significantly higher in the drain group only in the high-risk category. Prolonged length of hospital stay and composite morbidity remained higher in the drain group regardless of the risk category. CONCLUSION To our knowledge, this is the largest study to date that aims at clarifying the pros and cons of the intraperitoneal drain placement during pancreaticoduodenectomy for pancreatic tumors. We showed a higher 30-day mortality rate if drain insertion was omitted during pancreaticoduodenectomy in patients with softer pancreatic textures, smaller pancreatic duct caliber, and body mass index over 25. Postoperative 30-day morbidity rate was higher if a drain was inserted regardless of the risk category. Further randomized controlled trials with prospective evaluation of stratification factors for fistula risk are needed to establish a clear recommendation.

Abstract
The aim of the present study was to assess the effect of preoperative acute obstructive pancreatitis on the risk of the occurrence of pancreatic fistula (PF) following pancreaticoduodenectomy. A total of 22 patients who developed postoperative PF were carefully matched with 22 control patients without PF according to demographic data, pancreatic pathology, presenting symptoms and other surgery-associated parameters. These parameters were compared between these two groups. The mean pancreatic apparent diffusion coefficient (ADC) values in the fistula group were 1.14±0.31×10-3 mm2/s, which was significantly decreased compared with the non-fistula group (1.48±0.44×10-3 mm2/s) (P=0.005). The pancreas-muscle signal intensity (SI) ratio on fat-suppressed T1 weighted image (rT1) in the fistula group was 1.71±0.25, which was significantly increased compared with the non-fistula group (1.25±0.29) (P<0.001). The pancreas-muscle SI ratios on fat-suppressed T2 weighted image (T2WI) in the fistula group and the non-fistula group were 0.72±0.08 and 0.62±0.07, respectively (P=0.79). There was no significant difference in pancreas-muscle SI ratio on fat-suppressed T2-weighted image (rT2) value between these two groups. Based on the receiver operating characteristic curve, the optimal cut-off value of ADC as a criterion for prediction of pancreatic fistula was 1.29×10-3 mm2/s, which yielded a sensitivity of 77.3% and a specificity of 63.6%. In conclusion, the severity of acute obstructive pancreatitis was negatively associated with ADC values and pancreas-muscle SI ratio on rT1 images, which may be useful for predicting the occurrence of PF preoperatively.

Abstract
Laparoscopic lymph node dissection around the peripancreatic area for gastric cancer (GC) remains challenging because of drawbacks in laparoscopic surgery including the limited range of movement, amplification of hand tremors, and inconvenient surgical positioning. In some cases of laparoscopic gastrectomy (LG), therefore, postoperative pancreatic fistula (POPF) occurs. Robotic surgery, on the other hand, plays an essential role in ergonomics and offers advantages, such as motion scaling, less fatigue, tremor filtering, 7 degrees of motion in the robotic instruments assisted by the wrist-like instruments tips, and three-dimensional vision. Robotic gastrectomy (RG) may enable surgeons to overcome the drawbacks associated with laparoscopic surgery. This study compares the safety and feasibility of short-term surgical outcomes of RG and LG for patients with GC.This was a single-center retrospective study of 659 consecutive patients with GC who received minimally invasive surgery. LG (n = 639) was performed between 2013 and 2017 and RG (n = 20) was performed in 2017. Lymphadenectomy without touching the pancreas was basically performed during RG using assisting articulating forceps.Overall incidence of postoperative complications higher than Clavien-Dindo grade 2 was not significantly different (LG group 5.9%, RG group 5.0%). In RG group, POPF, intra-abdominal abscess, and anastomotic leakage were not found, but postoperative bleeding requiring interventional catheter embolization occurred in 1 patient. In LG, POPF was found in 4.7%. Amylase levels in drainage fluid on postoperative day 1 were significantly lower in the RG group (238.5 IU/L) than in the LG group (884.5 IU/L) (P = .028).Regarding short-term surgical outcomes, RG is feasible, safe, and ideal treatment procedure for GC. Our robotic procedure without touching the pancreas may be associated with decreased incidence of POPF.
