Meta-Analysis
Cardiovascular events are among the most common causes of late death in the transplant recipient (Tx) population. Moreover, major cardiac surgical procedures are more challenging and risky due to immunosuppression and the potential impact on the transplanted organ's functional capacity. We aimed to assess open cardiac surgery safety in abdominal solid organ transplant recipients, comparing the postoperative outcomes with those of nontransplant (N-Tx) patients. Electronic databases of PubMed, EMBASE, and SCOPUS were searched. The endpoints were: overall rate of infectious complications (wound infection, septicemia, pneumonia), cardiovascular and renal events (stroke, cardiac tamponade, acute kidney failure), 30-days, 5-years, and 10-years mortality post-cardiac surgery interventions in patients with and without prior solid organ transplantation. This meta-analysis included five studies. Higher rates of wound infection (Tx vs. N-Tx: OR: 2.03, 95% CI: 1.54 to 2.67, I2 = 0%), septicemia (OR: 3.91, 95% CI: 1.40 to 10.92, I2 = 0%), cardiac tamponade (OR: 1.83, 95% CI: 1.28 to 2.62, I2 = 0%) and kidney failure (OR: 1.70, 95 %CI: 1.44 to 2.02, I2 = 89%) in transplant recipients were reported. No significant differences in pneumonia occurrence (OR: 0.95, 95% CI: 0.71 to 1.27, I2 = 0%) stroke (OR: 0.89, 95% CI: 0.54 to 1.48, I2 = 78%) and 30-day mortality (OR: 1.92, 95% CI: 0.97 to 3.80, I2 = 0%) were observed. Surprisingly, 5-years (OR: 3.74, 95% CI: 2.54 to 5.49, I2 = 0%) and 10-years mortality rates were significantly lower in the N-Tx group (OR: 3.32, 95% CI: 2.35 to 4.69, I2 = 0%). Our study reveals that open cardiac surgery in transplant recipients is associated with worse postoperative outcomes and higher long-term mortality rates.

Meta-Analysis
Isolated peripancreatic necrosis (PPN) is associated with better clinical outcomes compared with combined pancreatic and peripancreatic involvement (CPN)- a systematic review and meta-analysis.
BACKGROUND AND AIMS
Peripancreatic necrosis (PPN) is considered as a distinct entity with a better outcome when compared with combined pancreatic and peripancreatic necrosis (CPN), but there is no systematic review to summarize the evidence. Our study aimed to perform a meta-analysis of existing observational studies comparing the outcomes of PPN with CPN.
METHODS
Studies in adult patients comparing the outcomes of PPN and CPN from PubMed, Medline, and Scopus databases from inception to November 2018 were systematically searched. The primary outcome was mortality, and secondary outcomes included multi-organ failure, persistent organ failure, infected necrosis, need for interventions including open necrosectomy. Pooled adjusted odds ratios, and 95% confidence intervals (CI) were obtained by the random-effects model. Forrest plots were constructed to show the summary pooled estimate. Heterogeneity was assessed by using I2 measure of inconsistency.
RESULTS
A total of 6 studies involving 1851 patients (1295 (70%) with CPN and 556 (30%) with PPN) were included. Patients with CPN had a significantly higher mortality (OR 2.49, 95% CI: 1.61-3.87), risk for multi-organ failure (OR 3.24, 95% CI: 2.38-4.43), persistent organ failure (OR 2.79, 95% CI: 1.53-5.08), and infected necrosis (OR 6.21, 95% CI: 3.85-10.03). They underwent more interventions (OR 5.86, 95% CI: 3.69-9.32), including open necrosectomy (OR 5.04, 95% CI: 3.33-7.63). Heterogeneity was low (I2 = 18.1, p = 0.296), and there was no publication bias.
CONCLUSION
Isolated peripancreatic necrosis portends an overall better prognosis when compared to necrosis involves pancreatic parenchyma. Clinicians should recognize this distinction for management decisions.

Meta-Analysis
PURPOSE
Acute pancreatitis is a potentially life-threatening condition with a wide spectrum of clinical presentation and illness severity. An infection of pancreatic necrosis (IPN) results in a more than twofold increase in mortality risk as compared with patients with sterile necrosis. We sought to identify prognostic factors for the development of IPN among adult patients with severe or necrotizing pancreatitis.
METHODS
We conducted this prognostic review in accordance with systematic review methodology guidelines. We searched six databases from inception through March 21, 2021. We included English language studies describing prognostic factors associated with the development of IPN. We pooled unadjusted odds ratio (uOR) and adjusted odds ratios (aOR) for prognostic factors using a random-effects model. We assessed risk of bias using the Quality in Prognosis Studies tool and certainty of evidence using the GRADE approach.
RESULTS
We included 31 observational studies involving 5,210 patients. Factors with moderate or higher certainty of association with increased IPN risk include older age (uOR, 2.19; 95% confidence interval [CI], 1.39-3.45, moderate certainty), gallstone etiology (aOR, 2.35; 95% CI, 1.36-4.04, high certainty), greater than 50% necrosis of the pancreas (aOR, 3.61; 95% CI, 2.15-6.04, high certainty), delayed enteral nutrition (aOR, 2.09; 95% CI, 1.26-3.47, moderate certainty), multiple or persistent organ failure (aOR, 11.71; 95% CI, 4.97-27.56, high certainty), and invasive mechanical ventilation (uOR, 12.24; 95% CI, 2.28-65.67, high certainty).
CONCLUSION
This meta-analysis confirms the association between several clinical early prognostic factors and the risk of IPN development among patients with severe or necrotizing pancreatitis. These findings provide the foundation for the development of an IPN risk stratification tool to guide more targeted clinical trials for prevention or early intervention strategies.

Meta-Analysis Review
BACKGROUND
Taking together the recent dramatic changes of the revised Atlanta classification and evidence newly obtained such as the role of step-up approach for necrotizing pancreatitis, the revision committee of the Japanese (JPN) Guidelines 2015 was prompted to perform an extensive revision of the guidelines.
METHODS
The JPN Guidelines 2015 was compared to the former edition 2010, and revision concepts and major revision points were reviewed. We compared the JPN 2015 with the other two guidelines, International Association of Pancreatology (IAP)/American Pancreas Association (APA) 2013 and American College of Gastroenterology (ACG) 2013, in order to clarify the distinct points.
RESULTS
The meta-analysis team conducted a new meta-analysis of four subjects that have been associated with conflicting results. It is apparent that the revised guidelines have been created more systematically and more objectively. As of antibiotics prophylaxis, its use in early phase (within 72 h of onset) for severe acute pancreatitis is recommended in JPN 2015 according to the results of original meta-analysis, whereas the other two guidelines do not recommend its routine use. An approach and management of local complications in necrotizing pancreatitis including infected necrosis are almost similar in the three guidelines. JPN 2015 alone emphasizes the implementation of the pancreatitis bundles that specify the management and treatment within the first 48 h after the onset of severe acute pancreatitis.
CONCLUSION
The JPN Guidelines 2015 prove to be the highest quality in terms of systematic literature review conducting original analyses by the meta-analysis team, determining the grading of recommendations and providing pancreatitis bundles.

Comparative Study Meta-Analysis
BACKGROUND
Pancreaticoduodenectomy/PD is a technically demanding pancreatic resection. Options of surgical reconstruction include (1) the child reconstruction defined as pancreatojejunostomy/PJ followed by hepaticojejunostomy/HJ and the gastrojejunostomy/GJ "the standard/s-Child," (2) the s-child reconstruction with an additional Braun enteroenterostomy "BE-Child," or (3) Isolated-Roux-En-Y-pancreaticojejunostomy "Iso-Roux-En-Y," in which the pancreas anastomosis is reconstructed in a separate loop after the GJ. Yet, the impact of these reconstruction methods on patients' outcome has not been sufficiently compared in a systematic manner.
METHODS
A systematic review and meta-analysis were conducted according to the Preferred-Reporting-Items-for-Systematic-review-and-Meta-Analysis/PRISMA-guidelines by screening Pubmed/Medline, Scopus, Cochrane Library and Web-of-Science. Articles meeting predefined criteria were extracted and meta-analysis was performed.
RESULTS
Nineteen studies were identified comparing BE-Child or Isolated-Roux-En-Y vs. s-Child. Compared to s-Child neither BE-Child (p = 0.43) nor Iso-Roux-En-Y (p = 0.94) displayed an impact on postoperative mortality, whereas BE-Child showed less postoperative complications (p = 0.02). BE-Child (p = 0.15) and Iso-Roux-En-Y (p = 0.61) did not affect postoperative pancreatic fistula/POPF in general, but BE-Child was associated with a decrease of clinically relevant POPF (p = 0.005), clinically relevant delayed gastric emptying/DGE B/C (p = 0.004), bile leaks (p = 0.01), and hospital stay (p = 0.06). BE-Child entailed also an increased operation time (p = 0.0002) with no impact on DGE A/B/C, hemorrhage, surgical site infections and pulmonary complications.
CONCLUSION
BE-Child is associated with a decreased risk for postoperative complications, particularly a decreased risk for clinically relevant DGE, POPF, and bile leaks, whereas Iso-Roux-En-Y does not seem to affect the clinical course after PD. Therefore, BE seems to be a valuable surgical method to improve patients' outcome after PD.

Scandinavian Journal of Gastroenterology Jul 2021To review clinical and laboratory findings in patients with SARS-Cov-2 (COVID-19) related acute pancreatitis.
OBJECTIVES
To review clinical and laboratory findings in patients with SARS-Cov-2 (COVID-19) related acute pancreatitis.
METHODS
This systematic review was based on a database search for articles of COVID-19 related acute pancreatitis in adult patients with confirmed COVID-19 infection that included age, gender, presenting symptoms, the onset of symptoms, laboratory values, imaging findings and exclusion of common causes of pancreatitis.
RESULTS
Altogether 35 articles comprising 37 patients were included. Acute pancreatitis was the first presentation of COVID-19 in 43% of patients, concurrent with general or respiratory symptoms in 14% of patients or delayed after general or pulmonary symptoms by an average of 10 ± 5 d (range, 1 - 19 d) in 43% of patients. Serum amylase and lipase levels were elevated in 87% and 100% of patients. In 50% and 84%, amylase and lipase levels exceeded three-fold the upper normal limit. Pancreatic necrosis was reported in 6% of patients and in 12% of patients, the pancreas appeared normal. Three patients died.
CONCLUSIONS
We conclude that the bi-modal pattern of the onset of symptoms supports both the cytotoxic and the immune-related pathogenesis of the pancreatic injury. Acute pancreatitis may be the first symptom of COVID-19 infection. Necrosis of the pancreas is rare.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the ongoing pandemic of coronavirus disease 2019 (COVID-19). Almost 17 months after the first COVID-19 case was reported, the exact pathogenesis of the virus is still open to interpretation. Postmortem studies have been relatively scarce due to the high infectivity rate of the virus. We systematically reviewed the literature available for studies that reported gross, histological, microscopic, and immunohistochemical findings in COVID-19 fatalities with the aim of reporting any recurrent findings among different demographics. PubMed and Scopus were searched up till the second of May 2021 and 46 studies with a total of 793 patients were shortlisted after the application of inclusion and exclusion criteria. The selected studies reported gross, histological, microscopic, and immunohistochemical autopsy findings in the lungs, heart, liver, gallbladder, bowels, kidney, spleen, bone marrow, lymph nodes, CNS, pancreas, endocrine/exocrine glands, and a few other miscellaneous locations. The SARS-CoV-2 virus was detected in multiple organs and so was the presence of widespread microthrombi. This finding suggests that the pathogenesis of this highly infectious virus might be linked to some form of coagulopathy. Further studies should focus on analyzing postmortem findings in a larger number of patients from different demographics in order to obtain more generalizable results.

Meta-Analysis
BACKGROUND
Risky consumption of alcohol is a global problem. More than 3.3 million deaths annually are associated with risky use of alcohol, and global alcohol consumption continues to increase. People who have high alcohol consumption often require planned and emergency surgical procedures.Risky drinking is associated with increased postoperative complications such as infections, cardiopulmonary complications, and bleeding episodes. Alcohol causes disorders of the liver, pancreas, and nervous system. Stopping consumption of alcohol can normalize these organ systems to some degree and may reduce the occurrence of complications after surgery.This review was first published in 2012 and was updated in 2018.
OBJECTIVES
To assess the effects of perioperative alcohol cessation interventions on rates of postoperative complications and alcohol consumption.
SEARCH METHODS
We searched the following databases up until 21 September 2018: Cochrane Central Register of Controlled Trials (CENTRAL), in the Cochrane Library; MEDLINE; Embase; CINAHL via EBSCOhost; and two trials registers. We scanned the reference lists and citations of included trials and any identified relevant systematic reviews for further references to additional trials. When necessary, we contacted trial authors to ask for additional information.
SELECTION CRITERIA
We included all randomized controlled trials (RCTs) that evaluated the effects of perioperative alcohol cessation interventions on postoperative complications and alcohol consumption. We included participants with risky consumption of alcohol who were undergoing all types of elective or acute surgical procedures under general or regional anaesthesia or sedation, who were offered a perioperative alcohol cessation intervention or no intervention.We defined 'risky drinking' as alcohol consumption equivalent to more than 3 alcoholic units (AU)/d or 21 AU/week (with 1 AU containing 12 grams of ethanol) with or without symptoms of alcohol abuse or dependency. This corresponds to the amount of alcohol associated with increased postoperative complication rates in most clinical studies.
DATA COLLECTION AND ANALYSIS
We used guidance provided in the Cochrane Handbook for Systematic Reviews of Interventions. We presented main outcomes as dichotomous variables in a meta-analysis. When data were available, we conducted subgroup and sensitivity analyses to explore the risk of bias. Primary outcome measures were postoperative complications and in-hospital and 30-day mortality. Secondary outcomes were successful quitting at the end of the programme, postoperative alcohol use, and length of hospital stay. We assessed the quality of evidence using the GRADE approach.
MAIN RESULTS
We included in this updated review one new study (70 participants), resulting in a total of three RCTs (140 participants who drank 3 to 40 AU/d). All three studies were of moderate to good quality. All studies evaluated the effects of intensive alcohol cessation interventions, including pharmacological strategies for alcohol withdrawal symptoms, patient education, and relapse prophylaxis. We identified one ongoing study.Overall, 53 of the 122 participants from three studies who underwent surgery developed any type of postoperative complication that required treatment. Of 61 participants in the intervention groups, 20 had complications, compared with 33 of 61 participants in the control groups (risk ratio (RR) 0.62, 95% confidence interval (CI) 0.40 to 0.96). Results show differences between the three clinical studies regarding outcome measurement and intensity of the interventions. However, all alcohol cessation programmes were intensive and included pharmacological therapy. The overall quality of evidence for this outcome is moderate.In-hospital and 30-day postoperative mortality rates were low in the three studies. Researchers reported one death among 61 participants in the intervention groups, and three deaths among 61 participants in the control groups (RR 0.47, 95% CI 0.07 to 2.96). The quality of evidence for this outcome is low.Investigators describe more successful quitters at the end of the intervention programme than among controls. Forty-one out of 70 participants in the intervention groups successfully quit drinking compared with only five out of 70 participants in the control groups (RR 8.22, 95% CI 1.67 to 40.44). The quality of evidence for this outcome is moderate.All three studies reported postoperative alcohol consumption (grams of alcohol/week) at the end of the programme as median and range values; therefore it was not possible to estimate the mean and the standard deviation (SD). We performed no meta-analysis. All three studies reported length of stay, and none of these studies described a significant difference in length of stay. Data were insufficient for review authors to perform a meta-analysis. No studies reported on the prevalence of participants without risky drinking in the longer term.
AUTHORS' CONCLUSIONS
This systematic review assessed the efficacy of perioperative alcohol cessation interventions for postoperative complications and alcohol consumption. All three studies showed a significant reduction in the number of participants who quit drinking alcohol during the intervention period. Intensive alcohol cessation interventions offered for four to eight weeks to participants undergoing all types of surgical procedures to achieve complete alcohol cessation before surgery probably reduced the number of postoperative complications. Data were insufficient for review authors to assess their effects on postoperative mortality. No studies reported an effect on length of stay, and no studies addressed the prevalence of risky drinking in the longer term.Included studies were few and reported small sample sizes; therefore one should be careful about drawing firm conclusions based on these study results. All three studies were conducted in Denmark, and most participants were men. The included participants may represent a selective group, as they could have been more motivated and/or more interested in participating in clinical research or otherwise different, and effects may have been overestimated for both intervention and control groups in these studies. Trial results indicate that these studies are difficult to perform, that strong research competencies are necessary for future studies, and that further evaluation of perioperative alcohol cessation interventions in high-quality randomized controlled trials is needed. Once published and assessed, the one 'ongoing' study identified may alter the conclusions of this review.

Comparative Study Meta-Analysis
BACKGROUND
Laparoscopy has been widely used in general surgical procedures, but total laparoscopic pancreaticoduodenectomy (TLPD) is still a complex and challenging surgery that is only performed in a small number of patients at a few large academic medical centers. Although the safety and feasibility of TLPD have been established, few studies have compared it with open pancreaticoduodenectomy (OPD) with regard to perioperative and oncological outcomes. Therefore, we carried out a meta-analysis to evaluate whether TLPD is superior to OPD.
AIM
To compare the treatment outcomes of TLPD and OPD in order to assess the safety and feasibility of TLPD.
METHODS
We conducted a systematic search of studies comparing TLPD with OPD that were published in the PubMed, EMBASE, and Cochrane Library databases through December 31, 2018. The studies comparing TLPD and OPD with at least one of the outcomes we were interested in and with more than 10 cases in each group were included in this analysis. The Newcastle-Ottawa scale was used to assess the quality of the nonrandomized controlled trials and the Jadad scale was used to assess the randomized controlled trials. Intraoperative data, postoperative complications, and oncologic outcomes were evaluated. The meta-analysis was performed using Review Manager Software version 5.3. Random or fixed-effects meta-analyses were undertaken to measure the pooled estimates.
RESULTS
A total of 4790 articles were initially identified for our study. After screening, 4762 articles were excluded and 28 studies representing 39771 patients (3543 undergoing TLPD and 36228 undergoing OPD) were eventually included. Patients who underwent TLPD had less intraoperative blood loss [weighted mean difference (WMD) = -260.08 mL, 95% confidence interval (CI): (-336.02, -184.14) mL, < 0.00001], a lower blood transfusion rate [odds ratio (OR) = 0.51, 95%CI: 0.36-0.72, = 0.0001], a lower perioperative overall morbidity (OR = 0.82, 95%CI: 0.73-0.92, = 0.0008), a lower wound infection rate (OR = 0.48, 95%CI: 0.34-0.67, < 0.0001), a lower pneumonia rate (OR = 0.72, 95%CI: 0.60-0.85, = 0.0002), a shorter duration of intensive care unit (ICU) stay [WMD = -0.28 d, 95%CI (-2.88, -1.29) d, < 0.00001] and a shorter length of hospital stay [WMD = -3.05 d, 95%CI (-3.93, -2.17), < 0.00001], a lower rate of discharge to a new facility (OR = 0.55, 95%CI: 0.39-0.78, = 0.0008), and a lower 30-d readmission rate (OR = 0.81, 95%CI: 0.68-0.95, = 0.10) than those who underwent OPD. In addition, the TLPD group had a higher R0 rate (OR = 1.28, 95%CI: 1.13-1.44, = 0.0001) and more lymph nodes harvested (WMD = 1.32, 95%CI: 0.57-2.06, = 0.0005) than the OPD group. However, the patients who underwent TLPD experienced a significantly longer operative time (WMD = 77.92 min, 95%CI: 40.89-114.95, < 0.0001) and had a smaller tumor size than those who underwent OPD [WMD = -0.32 cm, 95%CI: (-0.58, -0.07) cm, = 0.01]. There were no significant differences between the two groups in the major morbidity, postoperative pancreatic fistula, delayed gastric emptying, postpancreatectomy hemorrhage, bile leak, gastroenteric anastomosis fistula, intra-abdominal abscess, bowel obstruction, fluid collection, reoperation, ICU admission, or 30-d and 90-d mortality rates. For malignant tumors, the 1-, 2-, 3-, 4- and 5-year overall survival rates were not significantly different between the two groups.
CONCLUSION
This meta-analysis indicates that TLPD is safe and feasible, and may be a desirable alternative to OPD, although a longer operative time is needed and only smaller tumors can be treated.

INTRODUCTION
Periampular neoplasms represent 5% of all cancers of the gastrointestinal tract with peak incidence in the 7th decade of life. The most common clinical picture is jaundice, weight loss and abdominal pain. Considering that cholestasis is related to postoperative complications, preoperative biliary drainage was developed to improve the postoperative morbidity and mortality of icteric patients with periampular neoplasias, whether resectable or not.
OBJECTIVE
To describe the outcome of patients with periampullary tumors undergoing preoperative biliary drainage with pancreatoduodenectomy.
METHOD
The search was performed in the Medline/PubMed and Virtual Health Library databases by means of the combination of descriptors of the Medical Subject Headings. Inclusion criteria were clinical trials, cohorts, studies that analyze the morbidity and mortality of preoperative biliary drainage in Portuguese, English and Spanish. Exclusion criteria were studies published more than 10 years ago, experimental studies, systematic reviews and articles with WebQualis C or smaller journal in the area of Medicine I or Medicine III. Of the 196 references found, 46 were obtained for reading with quality assessed through the Checklist Strengthening the Reporting of Observational Studies in Epidemiology. Eight studies were selected for review.
RESULTS
A total of 1116 patients with a sample ranging from 48 to 280 patients and a mean age of 48 to 69 years were obtained. Of the eight studies, four observed a higher rate of bleeding in drained patients; three a higher rate of positive bile culture in the intervention group; site and cavitary infection, and biliopancreatic leaks were more common in the drainage group in two studies each. The death outcome and rate of reoperation were observed in larger numbers in the control group in one study each.
CONCLUSION
Preoperative intervention leads to a higher rate of infectious complications and bleeding.
