Meta-Analysis Review
OBJECTIVE
To assess the effectiveness of octreotide in preventing postoperative pancreatic fistula. Pancreatic fistula is one of the most common complications after elective pancreatic surgery. Several clinical trials have evaluated the use of octreotide to prevent the development of pancreatic fistula after pancreatic surgery with conflicting recommendations.
METHODS
We undertook a meta-analysis of 7 identified randomized controlled trials, reporting comparisons between octreotide and a control. The primary outcome was the incidence of postoperative pancreatic fistula, and the secondary outcome was the postoperative mortality.
RESULTS
Seven studies, involving 1359 patients, met the inclusion criteria for this review. In these studies, sample sizes ranged from 75 to 252 patients. In total, 679 patients were given octreotide and 680 patients formed the control group. Perioperative octreotide is associated with a significant reduction in the incidence of pancreatic fistula after elective pancreatic surgery, with a relative risk of 0.59 (95% confidence interval 0.41-0.85, p = 0.004). However, this risk reduction was not associated with a significant difference in postoperative mortality (p > 0.05).
CONCLUSIONS
The review revealed that perioperative octreotide is associated with a significant reduction in the incidence of pancreatic fistula after elective pancreatic surgery. However, this risk reduction was not associated with a significant difference in postoperative mortality; further studies are warranted to confirm the results of this metaanalysis and to define which patient subgroups might benefit the most from prophylactic octreotide administration.

Review
INTRODUCTION
Pancreaticopleural fistula is a rare complication of chronic pancreatitis.
OBJECTIVE
To describe pancreaticopleural fistula due to chronic pancreatitis and perform an extensive review of literature on this topic.
METHODS
Comprehensive narrative review through online research on the databases Medline and Lilacs for articles published over the last 20 years. There were 22 case reports and four case series selected.
RESULTS
The main indication for surgical treatment is the failure of clinical and/or endoscopic treatments. Surgery is based on internal pancreatic drainage, especially by means of pancreaticojejunostomy, and/or pancreatic resections.
CONCLUSION
Pancreaticopleural fistula is a rare complication of chronic pancreatitis and the Frey procedure may be an appropriate therapeutic option in selected cases when clinical and endoscopic treatments are unsuccessful.

BACKGROUND/OBJECTIVE
Pancreaticoduodenectomy (PD) is highly invasive with unsatisfactory postoperative complication rates. Nutritional and fluid management after major surgery attracts much attention with regard to the reduction in severe postoperative complications. We retrospectively analyzed PD cases and proposed a novel strategy for perioperative fluid and nutritional therapy according to the risk stratification by pancreatic fistula (PF) and delayed gastric emptying (DGE).
METHODS
Between 2003 and 2018, 140 patients underwent PD at our institute of which 134 patients were enrolled. We evaluated the clinicopathological factors affecting severe (≥10%) body weight loss (BWL), factors affecting the incidence of PF and intraabdominal complications (IAC), and factors related to DGE.
RESULTS
Multivariate analysis indicated that male sex, severe PF, and DGE are significant risk factors for BWL ≥10%. PF and IAC were predominantly observed in male patients and those with non-pancreatic cancer. A fluid balance ≥6000 ml on postoperative day 2 was the sole risk factor for primary DGE. Secondary DGE significantly correlated with stomach preserving PD. Importantly, the average BWL was around 15% in grade B or C secondary DGE.
CONCLUSION
Severe postoperative complications resulted in significant BWL. Enteral feeding is unnecessary in cases with a hard pancreas and dilated pancreatic duct if appropriate perioperative fluid management is performed. Secondary DGE followed by PF or IAC is unavoidable to some extent, especially in the case of soft pancreas with a fine pancreatic duct. In such cases, enteral feeding with tube ileostomy should be considered, and stomach preserving PD is likely to be harmful.

Risk factor analysis of postoperative pancreatic fistula after distal pancreatectomy, with a focus on pancreas-visceral fat CT value ratio and serrated pancreatic contour.
BACKGROUND
In pancreaticoduodenectomy, the pancreas-visceral fat CT value ratio and serrated pancreatic contour on preoperative CT have been revealed as risk factors for postoperative pancreatic fistulas. We aimed to evaluate whether they could also serve as risk factors for postoperative pancreatic fistulas after distal pancreatectomy.
METHODS
A total of 251 patients that underwent distal pancreatectomy at our department from 2006 to 2020 were enrolled for the study. We retrospectively analyzed risk factors for postoperative pancreatic fistulas after distal pancreatectomy using various pre and intraoperative factors, including preoperative CT findings, such as pancreas-visceral fat CT value ratio and serrated pancreatic contour.
RESULTS
The study population included 147 male and 104 female participants (median age, 68 years; median body mass index, 21.4 kg/m), including 64 patients with diabetes mellitus (25.5%). Preoperative CT evaluation showed a serrated pancreatic contour in 80 patients (31.9%), a pancreatic thickness of 9.3 mm (4.0-22.0 mm), pancreatic parenchymal CT value of 41.8 HU (4.3-22.0 HU), and pancreas-visceral fat CT value ratio of - 0.41 (- 4.88 to - 0.04). Postoperative pancreatic fistulas were developed in 34.2% of the patients. Univariate analysis of risk factors for postoperative pancreatic fistulas showed that younger age (P = 0.005), high body mass index (P = 0.001), absence of diabetes mellitus (P = 0.002), high preoperative C-reactive protein level (P = 0.024), pancreatic thickness (P < 0.001), and high pancreatic parenchymal CT value (P = 0.018) were significant risk factors; however, pancreas-visceral fat CT value ratio (P = 0.337) and a serrated pancreatic contour (P = 0.122) did not serve as risk factors. Multivariate analysis showed that high body mass index (P = 0.032), absence of diabetes mellitus (P = 0.001), and pancreatic thickness (P < 0.001) were independent risk factors.
CONCLUSION
The pancreas-visceral fat CT value ratio and serrated pancreatic contour evaluated using preoperative CT were not risk factors for postoperative pancreatic fistulas after distal pancreatectomy. High body mass index, absence of diabetes mellitus, and pancreatic thickness were independent risk factors, and a close-to-normal pancreas with minimal fat deposition or atrophy is thought to indicate a higher risk of postoperative pancreatic fistulas after distal pancreatectomy.

Effects of early enteral nutrition on pancreatic fistula and long-term prognosis after distal pancreatectomy or enucleation of pancreatic tumours in a major academic university hospital in China: protocol for a single-centre randomised controlled trial.
INTRODUCTION
Postoperative pancreatic fistula (POPF) remains one of the main complications following pancreatic resection. Despite pancreatic fistula having a low postoperative mortality rate, the readmission and intervention rates in patients with pancreatic fistula are still considerable. Although there are several studies on pancreatic fistula development after pancreaticoduodenectomy, there are only a few studies on the feeding protocols applied after distal pancreatectomy or enucleation of pancreatic tumours. We designed this trial to test the hypothesis that early feeding does not increase the incidence of POPF and positively influences the long-term prognosis in patients who undergo distal pancreatectomy or enucleation of pancreatic tumours.
METHODS AND ANALYSIS
This is a prospective randomised controlled trial that will be conducted in a single centre. A total of 106 patients undergoing distal pancreatectomy or enucleation of pancreatic tumours will be recruited after providing informed consent. They will be randomly assigned to either an early or late feeding group. The early feeding group will begin enteral nutrition on postoperative day (POD) 3, and the late feeding group will begin enteral nutrition on POD7. The primary outcome is the incidence of POPF. The secondary outcomes include the length of postoperative hospital stay, postoperative complications, and indicators of long-term prognosis.
ETHICS AND DISSEMINATION
Peking University Third Hospital Medical Science Research Ethics Committee approved the study (M2021395). Findings will be disseminated in a peer-reviewed journal and in national and/or international meetings to guide future practice.

AIM
To investigate potential biomarkers for predicting postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD).
METHODS
We prospectively recruited 83 patients to this study. All patients underwent PD (Child's procedure) at the Division of Hepatobiliary and Pancreas Surgery at the First Bethune Hospital of Jilin University between June 2011 and April 2015. Data pertaining to demographic variables, clinical characteristics, texture of pancreas, surgical approach, histopathological results, white blood cell count, amylase and choline levels in the serum, pancreatic/gastric drainage fluid, and choline and amylase levels in abdominal drainage fluid were included in the analysis. Potential correlations between these parameters and postoperative complications such as, POPF, acute pancreatitis, hemorrhage, delayed gastric emptying, and biliary fistula, were assessed.
RESULTS
Twenty-eight out of the 83 (33.7%) patients developed POPF. The severity of POPF was classified as Grade A in 8 (28%) patients, grade B in 16 (58%), and grade C in 4 (14%), according to the pancreatic fistula criteria. On univariate and multivariate logistic regression analyses, higher amylase level in the abdominal drainage fluid on postoperative day (POD)1 and higher serum amylase levels on POD4 showed a significant correlation with POPF ( < 0.05). On receiver operating characteristic curve analysis, amylase cut-off level of 2365.5 U/L in the abdominal drainage fluid was associated with a 78.6% sensitivity and 80% specificity [area under the curve (AUC): 0.844; = 0.009]. A cut-off serum amylase level of 44.2 U/L was associated with a 78.6% sensitivity and 70.9% specificity (AUC: 0.784; = 0.05).
CONCLUSION
Amylase level in the abdominal drainage fluid on POD1 and serum amylase level on POD4 represent novel biomarkers associated with POPF development.

Meta-Analysis Review
BACKGROUND
No consensus was reached with regard to the effect of EDR on postoperative outcomes after pancreatic surgery. The meta-analysis was designed to explore the efficacy and safety of early drain removal (EDR).
METHODS
Systematic literature search was performed. Data extraction and correction were performed by three researchers. For dichotomous and continuous outcomes, we calculated the pooled risk difference and mean difference with 95% confidence intervals, respectively. The heterogeneity of included studies was evaluated using Cochran's Q and I test. The stratified analyses of pancreaticoduodenectomy (PD) and distal pancreatectomy (DP) were performed.
RESULTS
A total of 10 studies including 3 RCTs and 7 non RCTs were included for meta-analysis, among which 1780 patients with EDR and 5613 patients with late drain removal (LDR) were enrolled. The meta-analysis of both all the available studies and studies only with selected low risk patients indicated that EDR group had significantly lower incidences of Grade B/C postoperative pancreatic fistula (POPF) and total complications for both PD and DP. However, no advantages of EDR were observed in the meta-analysis of the 3 RCTs. In addition, EDR was associated with a lower incidence of intra-abdominal infection after PD. While for DP, EDR group had decreased risk of delayed gastric emptying and re-operation, and shorter postoperative in-hospital stay.
CONCLUSIONS
The meta-analysis demonstrates that EDR is effective and safe for both PD and DP considering POPF and total complications, especially for patients with low concentration of postoperative drain fluid amylase.

Review
Pancreatic fistula after pancreaticoduodenectomy represents a critical trigger of potentially life-threatening complications and is also associated with markedly prolonged hospitalization. Many arguments have been proposed for the method to anastomosis the pancreatic stump with the gastrointestinal tract, such as invagination vs. duct-to-mucosa, Billroth I (Imanaga) vs. Billroth II (Whipple and/or Child) or pancreaticogastrostomy vs. pancreaticojejunostomy. Although the best method for dealing with the pancreatic stump after pancreaticoduodenectomy remains in question, recent reports described the invagination method to decrease the rate of pancreatic fistula significantly compared to the duct-to-mucosa anastomosis. In Billroth I reconstruction, more frequent anastomotic failure has been reported, and disadvantages of pancreaticogastrostomy have been identified, including an increased incidence of delayed gastric emptying and of pancreatic duct obstruction due to overgrowth by the gastric mucosa. We review recent several safety trials and methods of treating the pancreatic stump after pancreaticoduodenectomy, and demonstrate an operative procedure with its advantage of the novel reconstruction method due to our experiences.

Review
BACKGROUND
A post-operative pancreatic fistula (POPF) is a major cause of morbidity and mortality after a pancreaticoduodenectomy (PD). This systematic review aimed to identify all scoring systems to predict POPF after a PD, consider their clinical applicability and assess the study quality.
METHOD
An electronic search was performed of Medline (1946-2014) and EMBASE (1996-2014) databases. Results were screened according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and quality assessed according to the QUIPS (quality in prognostic studies) tool.
RESULTS
Six eligible scoring systems were identified. Five studies used the International Study Group on Pancreatic Fistula (ISGPF) definition. The proposed scores feature between two and five variables and of the 16 total variables, the majority (12) featured in only one score. Three scores could be fully completed pre-operatively whereas 1 score included intra-operative and two studies post-operative variables. Four scores were internally validated and of these, two scores have been subject to subsequent multicentre review. The median QUIPS score was 38 out of 50 (range 16-50).
CONCLUSION
These scores show potential in calculating the individualized patient risk of POPF. There is, however, much variation in current scoring systems and further validation in large multicentre cohorts is now needed.

Video Grading of Pancreatic Anastomoses During Robotic Pancreatoduodenectomy to Assess Both Learning Curve and the Risk of Pancreatic Fistula: A Post Hoc Analysis of the LAELAPS-3 Training Program.
OBJECTIVE
To assess the learning curve of pancreaticojejunostomy during robotic pancreatoduodenectomy (RPD) and to predict the risk of postoperative pancreatic fistula (POPF) by using the objective structured assessment of technical skills (OSATS), taking the fistula risk into account.
BACKGROUND
RPD is a challenging procedure that requires extensive training and confirmation of adequate surgical performance. Video grading, modified for RPD, of the pancreatic anastomosis could assess the learning curve of RPD and predict the risk of POPF.
METHODS
Post hoc assessment of patients prospectively included in 4 Dutch centers in a nationwide LAELAPS-3 training program for RPD. Video grading of the pancreaticojejunostomy was performed by 2 graders using OSATS (attainable score: 12-60). The main outcomes were the combined OSATS of the 2 graders and POPF (grade B/C). Cumulative sum analyzed a turning point in the learning curve for surgical skill. Logistic regression determined the cutoff for OSATS. Patients were categorized for POPF risk (ie, low, intermediate, and high) based on the updated alternative fistula risk scores.
RESULTS
Videos from 153 pancreatic anastomoses were included. Median OSATS score was 48 (interquartile range: 41-52) points and with a turning point at 33 procedures. POPF occurred in 39 patients (25.5%). An OSATS score below 49, present in 77 patients (50.3%), was associated with an increased risk of POPF (odds ratio: 4.01, P =0.004). The POPF rate was 43.6% with OSATS < 49 versus 15.8% with OSATS ≥49. The updated alternative fistula risk scores category "soft pancreatic texture" was the second strongest prognostic factor of POPF (odds ratio: 3.37, P =0.040). Median cumulative surgical experience was 17 years (interquartile range: 8-21).
CONCLUSIONS
Video grading of the pancreatic anastomosis in RPD using OSATS identified a learning curve and a reduced risk of POPF in case of better surgical performance. Video grading may provide a valid method to surgical training, quality control, and improvement.
