Meta-Analysis Review
INTRODUCTION
Post-operative pancreatic fistula (POPF) is a common complication after partial pancreatic resection, and is associated with increased rates of sepsis, mortality and costs. The role of fibrin sealants in decreasing the risk of POPF remains debatable. The aim of this study was to evaluate the literature regarding the effectiveness of fibrin sealants in pancreatic surgery.
METHODS
A comprehensive database search was conducted. Only randomized controlled trials comparing fibrin sealants with standard care were included. A meta-analysis regarding POPF, intra-abdominal collections, post-operative haemorrhage, pancreatitis and wound infections was performed according to the recommendations of the Cochrane collaboration.
RESULTS
Seven studies were included, accounting for 897 patients. Compared with controls, patients receiving fibrin sealants had a pooled odds ratio (OR) of developing a POPF of 0.83 [95% confidence interval (CI): 0.6-1.14], P = 0.245. There was a trend towards a reduction in post-operative haemorrhage (OR = 0.43 (95%CI: 0.18-1.0), P = 0.05) and intra-abdominal collections (OR = 0.52 (95%CI: 0.25-1.06), P = 0.073) in those patients receiving fibrin sealants. No difference was observed in terms of mortality, wound infections, re-interventions or hospital stay.
CONCLUSION
On the basis of these results, fibrin sealants cannot be recommended for routine clinical use in the setting of pancreatic resection.

Meta-Analysis Review
Postoperative pancreatic fistula (POPF) is a common complication following distal pancreatectomy (DP). However, the risk factors of this complication in patients after DP still remain controversial. The aim of our study is to estimate the association between potential risk factors and POPF. Relevant articles published up to June 21, 2016 were identified via PubMed, EMBASE, Web of Science, and The Cochrane Library. Studies that examined the risk factors of POPF following DP were enrolled. 20 articles (2070 patients) were finally included in this study. The pooled data suggested that patients with soft pancreas, higher Body Mass Index (BMI), blood transfusion, elevated intraoperative blood loss, and longer operative time had a decreased risk for POPF. However, age, gender, malignant pathology, types of stump closure, octreotide therapy, history of diabetes and chronic pancreatitis, splenectomy, multiorgan resection, main duct ligation, preoperative serum albumin levels, PGA felt wrapping, and extended lymphadenectomy could not be regarded as risk factors for POPF. Our analytic data demonstrated that pancreas texture, BMI, blood transfusion, intraoperative blood loss, and operative time were clinical predictor for POPF. This study may assist surgeons to screen patients with high risk of POPF and select appropriate treatment measures.

Meta-Analysis
BACKGROUND
Body composition analysis has emerged as a practical tool for predicting outcomes following pancreatic surgery. However, the impact of body composition disorders on clinically relevant postoperative pancreatic fistula (CR-POPF) remains inconclusive. The aim of this study was to review and analyse whether radiographically assessed body composition is predictive of CR-POPF.
METHODS
PubMed, MEDLINE, Web of Science, and the Cochrane Library databases were searched up to January 2020 to identify relevant studies. CR-POPF was defined according to the definition and grading system proposed by the International Study Group on Pancreatic Surgery (ISGPS). Pooled odds ratios (OR) for CR-POPF were calculated to evaluate the predictive values of radiographically assessed body composition.
RESULTS
Fifteen studies published between 2008 and 2019 with a total of 3136 patients were included. There was a significant increase in the incidence of CR-POPF in patients with visceral obesity (OR 2.97, 95% CI 2.05-4.29, P < 0.00001) and sarcopenic obesity (OR 2.88, 95% CI 1.31-6.34, P = 0.009). Conversely, the impact of sarcopenia (OR 0.91, 95% CI 0.65-1.28, P = 0.59) and low muscle attenuation (MA) on CR-POPF did not reach statistical significance.
CONCLUSION
Preoperative visceral obesity and sarcopenic obesity are more effective at predicting CR-POPF than decreased muscle quantity and quality. This finding may lead to appropriate management and early intervention of patients at risk of CR-POPF.

BACKGROUND
Pancreatic enucleation (pEN) as parenchyma-sparing procedure for small pancreatic neoplasms is quickly becoming the most common surgical option in such setting. Nowadays, pEN is frequently carried out through a minimally invasive approach either laparoscopic or robotic. Its impact on overall perioperative complications and pancreatic fistula (POPF) is still under evaluation. The scope of our systematic review is to assess pEN's perioperative outcomes and to evaluate the effect of the minimally invasive techniques over POPF and other surgical complications.
METHODS
We performed a systematic literature search (time-frame January 1999-September 2018), considering exclusively those studies which included at least 5 cases of either open or minimally invasive pEN. Data regarding postoperative outcome and POPF were extracted and analyzed. We defined postoperative morbidities by the Clavien-Dindo classification while POPF according to the International Study Group of Pancreatic Fistula (ISGPF) definition.
RESULTS
Sixty-three studies met the criteria selected, accounting for a study population of 2485 patients. 27.7% had a minimally invasive pEN. The overall postoperative morbidity rate was 46.1% with 11.9% rated as severe (Clavien-Dindo ≥ 3). Mortality rate was 0.69%. The minimally invasive approach to pEN led to a statistically significant reduction of both the overall POPF rate (28.7% vs. 45.9%, p < 0.001), and clinically significant B-C POPF (p < 0.027). The postoperative overall morbidity rate was clearly in favor of the minimally invasive approach (27.6% vs. 55.2%, p < 0.001).
CONCLUSIONS
Our review confirms that pEN is a safe and feasible technique for the treatment of small benign or low-grade pancreatic neoplasms and it can be implemented with an acceptable morbidity rate along with low mortality. The minimally invasive approach is gaining widespread acceptance due to its supposed non-inferiority compared with the traditional open approach. In our review, it showed to be even better in terms of POPF incidence rate and short-term postoperative outcome. Still, such data need to be corroborated by randomized clinical trials.

Meta-Analysis Review
BACKGROUND
Pancreaticoduodenectomy is the first choice surgical intervention for the radical treatment of pancreatic tumors. However, an anastomotic fistula is a common complication after pancreaticoduodenectomy with a high mortality rate. With the development of minimally invasive surgery, open pancreaticoduodenectomy (OPD), laparoscopic pancreaticoduodenectomy (LPD), and robotic pancreaticoduodenectomy (RPD) are gaining interest. But the impact of these surgical methods on the risk of anastomosis has not been confirmed. Therefore, we aimed to integrate relevant clinical studies and explore the effects of these three surgical methods on the occurrence of anastomotic fistula after pancreaticoduodenectomy.
METHODS
A systematic literature search was conducted for studies reporting the RPD, LPD, and OPD. Network meta-analysis of postoperative anastomotic fistula (Pancreatic fistula, biliary leakage, gastrointestinal fistula) was performed.
RESULTS
Sixty-five studies including 10,026 patients were included in the network meta-analysis. The rank of risk probability of pancreatic fistula for RPD (0.00) was better than LPD (0.37) and OPD (0.62). Thus, the analysis suggests the rank of risk of the postoperative pancreatic fistula for RPD, LPD, and OPD. The rank of risk probability for biliary leakage was similar for RPD (0.15) and LPD (0.15), and both were better than OPD (0.68).
CONCLUSIONS
This network meta-analysis provided ranking for three different types of pancreaticoduodenectomy. The RPD and LPD can effectively improve the quality of surgery and are safe as well as feasible for OPD.

Meta-Analysis Review
BACKGROUND
Postoperative pancreatic leakage after pancreaticoduodenectomy is often serious. Although some studies have suggested that stenting the anastomosis can reduce the incidence of this complication, the value of stenting in the setting of pancreaticoduodenectomy remains unclear.
METHODS
Studies comparing outcomes of stent versus no stent, and internal versus external stent placement for pancreaticoduodenectomy were eligible for inclusion. Pooled odds ratios (ORs) with 95 per cent confidence intervals were calculated using fixed- or random-effects models.
RESULTS
From a search of the literature published between January 1973 and September 2011, five randomized clinical trials (RCTs) and 11 non-randomized observational clinical studies (OCS) involving 1726 patients were selected for inclusion in this review. Meta-analysis of RCTs revealed that placing a stent in the pancreatic duct did not reduce the incidence of postoperative pancreatic fistula. External stents had no advantage over internal stents in terms of clinical outcome. Subgroup analyses revealed that use of an external stent significantly reduced the incidence of pancreatic fistula (RCTs: OR 0·42, 0·24 to 0·76, P = 0·004; OCS: OR 0·43, 0·27 to 0·68, P < 0·001), delayed gastric emptying (RCTs: OR 0·41, 0·19 to 0·87, P = 0·02) and postoperative morbidity (RCTs: OR 0·55, 0·34 to 0·89, P = 0·02) compared with no stent.
CONCLUSION
Pancreatic duct stenting did not reduce the incidence of pancreatic fistula and other complications in pancreaticoduodenectomy compared with no stenting. Although no difference was found between external and internal stents in terms of efficacy, external stents seemed to reduce the incidence of pancreatic fistula compared with control.

Meta-Analysis Review
BACKGROUND
In the past decade, Enhanced Recovery after Surgery (ERAS) protocols have been implemented in several fields of surgery. With these protocols, a faster recovery and shorter hospital stay can be accomplished without an increase in morbidity or mortality. The purpose of this study was to review systematically the evidence for implementation of an ERAS protocol in pancreatic resections, with particular emphasis on pancreaticoduodenectomies (PDs).
METHODS
A systematic search was performed in Medline, Embase, Pubmed, CINAHL, and the Cochrane library for papers describing an ERAS program in adult patients undergoing elective pancreatic surgery published between January 1966 and December 2012. The primary outcome measure was postoperative length of stay. Secondary outcome measures were time to recovery of normal function, overall postoperative complication rates, readmissions, and mortality. Subsequently, a meta-analysis of outcome measures focusing on PD was conducted. This systematic review and meta-analysis was performed according to the PRISMA statement.
RESULTS
The literature search produced 248 potentially relevant papers. Of these, eight papers met the predefined inclusion criteria: five case-control studies, two retrospective studies, and one prospective study, describing a total of 1,558 patients. Only three of the studies reported data on discharge criteria and assessed time to recovery and return to normal function. Implementation of an ERAS protocol led in four of five comparative studies to a significant decrease in length of stay (reduction of 2-6 days in different studies). Meta-analysis of four studies focusing on PDs showed that there was a significant difference in complication rates in favor of the ERAS group (absolute risk difference 8.2 %, 95 % confidence interval (CI) 2.0-14.4, p = 0.008). Introduction of an ERAS protocol did not result in an increase in mortality or readmissions. Delayed gastric emptying and incidence of pancreatic fistula did not differ significantly between groups. All studies reporting on hospital costs showed a decrease after implementation of ERAS.
CONCLUSIONS
This systematic review suggests that using an ERAS protocol in pancreatic resections may help to shorten hospital length of stay without compromising morbidity and mortality. This seemed to apply to distal pancreatectomy, total pancreatectomy, and PD. Meta-analysis was performed for those studies focusing on PD and showed that there were no differences in readmission or mortality. Morbidity rates were significantly lower for patients managed according ERAS principles.

Autologous but not Fibrin Sealant Patches for Stump Coverage Reduce Clinically Relevant Pancreatic Fistula in Distal Pancreatectomy: A Systematic Review and Meta-analysis.
BACKGROUND
Postoperative pancreatic fistula (POPF) causes significant morbidity and mortality after distal pancreatectomy. Patch coverage of the pancreatic stump is often used with the intention to prevent POPF. Despite numerous investigations, the effects of patch coverage remain unclear. The present meta-analysis aims to clarify the effects of patch coverage in distal pancreatectomy on the incidence of POPF.
METHODS
A systematic search of MEDLINE/PubMed and the Cochrane Database according to the PRISMA Statement was performed. Subsequently a meta-analysis on rates and overall incidence of POPF and length of hospital stay was carried out. By applying the inverse variance weighting method, the combined effect size and 95 % confidence interval were calculated. Heterogeneity was assessed using I statistics.
RESULTS
Five randomized controlled trials and six observational clinical studies were included for final analysis. A cumulative incidence of 43 % of POPF grades A-C was identified. Patch coverage in distal pancreatectomy is significantly associated with a decreased rate of POPF grade C (p = 0.006). Patches of autologous vascularized tissue significantly reduce the overall incidence of POPF (p = 0.04) and clinically relevant POPF grade B and C (p = 0.002). Fibrin sealant patches do not influence rates of POPF after distal pancreatectomy. None of the outcomes evaluated showed adverse results for the patch group.
CONCLUSIONS
Patch coverage after distal pancreatectomy can reduce the rate of POPF. Patch coverage with autologous vascularized tissue but not fibrin sealant patches may be used to reduce clinically relevant POPF and postoperative morbidity in distal pancreatectomy.

Meta-Analysis Review
Systematic review and meta-analysis of risk factors of postoperative pancreatic fistula after distal pancreatectomy in the era of 2016 International Study Group pancreatic fistula definition.
BACKGROUND
Risk factors for the development of clinically relevant POPF (CR-POPF) following distal pancreatectomy (DP) need clarification particularly following the 2016 International Study Group of Pancreatic Fistula (ISGPF) definition.
METHODS
A systemic search of MEDLINE, Pubmed, Scopus, and EMBASE were conducted using the PRISMA framework. Studies were evaluated for risk factors for the development CR-POPF after DP using the 2016 ISGPF definition. Further subgroup analysis was undertaken on studies ≥10 patients in exposed and non-exposed subgroups.
RESULTS
Forty-three studies with 8864 patients were included in the meta-analysis. The weighted rate of CR-POPF was 20.4% (95%-CI: 17.7-23.4%). Smoking (OR 1.29, 95%-CI: 1.08-1.53, p = 0.02) and open DP (OR 1.43, 95%-CI: 1.02-2.01, p = 0.04) were found to be significant risk factors of CR-POPF. Diabetes (OR 0.81, 95%-CI: 0.68-0.95, p = 0.02) was a significant protective factor against CR-POPF. Substantial heterogeneity was observed in the comparisons of pancreatic texture and body mass index. Seventeen risk factors achieved significance in a univariate or multivariate comparison as reported by individual studies in the narrative synthesis, however, they remain difficult to interpret as statistically significant comparisons were not uniform.
CONCLUSION
This meta-analysis found smoking and open DP to be risk factors and diabetes to be protective factor of CR-POPF in the era of 2016 ISGPF definition.

Meta-Analysis
Postoperative pancreatic fistula (POPF) is the most common and intractable complication after partial pancreatectomy, with an incidence of 13% to 64%. Polyglycolic acid (PGA) mesh is a new technique that is designed to prevent POPF, and its effect has been evaluated in several randomized controlled trials and some retrospective cohort studies. In this study, we systematically and comprehensively analyzed the efficacy of PGA mesh based on reported studies.We searched Medline, Embase, and Cochrane Library databases in English between January 2010 and October 2019. Analysis was performed by using Review Manger 5.3 software.Three RCTs and 8 nonrandomized studies were eligible with a total of 1598 patients including 884 PGA group patients and 714 control group patients. For pancreatoduodenectomy (PD), distal pancreatectomy (DP), and the 2 partial pancreatectomy (PD or DP), we found significant statistical differences in overall POPF (relative risk [RR] = 0.75, 95% confidence interval [CI] = 0.61-0.91, P = .004; RR = 0.74, 95% CI = 0.57-0.96, P = .02; RR = 0.76, 95% CI = 0.64-0.89, P = .0009, respectively) and clinical pancreatic fistula (PF) (RR = 0.5, 95% CI = 0.37-0.68, P < .00001; RR = 0.31, 95% CI = 0.21-0.46, P < .00001; RR = 0.41, 95% CI = 0.32-0.52, P < .00001, respectively) in favor of PGA. For partial pancreatectomy, significant statistical differences were found in overall complications (RR = 0.77, 95% CI: 0.67-0.88, P = .0002) and estimated blood loss (weighted mean difference [WMD] = -53.58; 95% CI: -101.20 to -5.97, P = .03) in favor of PGA. We did not find significant differences regarding operative time (WMD = -8.86; 95% CI: -27.59 to 9.87, P = .35) and hospital stay (WMD = -2.73; 95% CI: -7.53 to 2.06, P = .26).This meta-analysis shows the benefits of the PGA mesh technique regarding POPF, clinical PF, and postoperative complications. This still needs to be verified by more randomized control trials.
