Meta-Analysis Review
BACKGROUND AND AIMS
Previous studies have demonstrated that the ideal time for drainage of walled-off pancreatic fluid collections is 4 to 6 weeks after their development. However, some pancreatic collections, notably infected pancreatic fluid collections, require earlier drainage. Nevertheless, the optimal timing of the first intervention is unclear, and consensus data are sparse. The aim of this study was to evaluate the clinical efficacy and safety of EUS-guided drainage of pancreatic fluid collections <4 weeks after development compared with ≥4 weeks after development.
METHODS
Search strategies were developed for PubMed, Embase, and Cochrane Library databases from inception. Outcomes of interest were technical success, defined as successful endoscopic placement of a lumen-apposing metal stent; clinical success, defined as a reduction in cystic collection size; and procedure-related adverse events. A random-effects model was used for analysis, and results are expressed as odds ratio (OR) with 95% confidence interval (CI).
RESULTS
Six studies (630 patients) were included in our final analysis, in which 182 patients (28.9%) were enrolled in the early drainage cohort and 448 patients (71.1%) in the standard drainage cohort. The mean fluid collection size was 143.4 ± 18.8 mm for the early cohort versus 128 ± 19.7 mm for the standard cohort. Overall, technical success was equal in both cohorts. Clinical success did not favor either standard drainage or early drainage (OR, .39; 95% CI, .13-1.22; P = .11). No statistically significant differences were found in overall adverse events (OR, 1.67; 95% CI, .63-4.45; P = .31) or mortality (OR, 1.14; 95% CI, .29-4.48; P = .85). Hospital stay was longer for patients undergoing early drainage compared with standard drainage (23.7 vs 16.0 days, respectively).
CONCLUSIONS
Both early (<4 weeks) and standard (≥4 weeks) drainage of walled-off pancreatic fluid collections offer similar technical and clinical outcomes. Patients requiring endoscopic drainage should not be delayed for 4 weeks.

The Journal of International Medical... Sep 2022This study reviewed the current evidence on the clinical characteristics and outcome of acute pancreatitis (AP) following spinal surgery.
OBJECTIVE
This study reviewed the current evidence on the clinical characteristics and outcome of acute pancreatitis (AP) following spinal surgery.
METHODS
A systematic search was performed to identify English articles published through May 2020 in PubMed, Scopus, EMBASE, Latin American & Caribbean Health Sciences Literature, and Cochrane Library. Data on clinical characteristics, risk factors, and outcomes were analyzed.
RESULTS
Eleven papers (including six case reports) were included, with 306 patients (incidence, 23.0%) developing AP after spinal surgery (mean age, 14.2 years). Of the studies that specified symptoms (55 patients), abdominal pain (43.6%), nausea and vomiting (32.7%), and abdominal distension (7.27%) were most prevalent. The mean duration from surgery to symptom onset was 6.15 days (range, 1-7). The most common complications of AP were glucose intolerance (25%), peritonitis (2%), pseudocyst formation (2%), and fluid collection (2%) were most prevalent. Prolonged fasting time (13.6%), intraoperative blood loss (9.09%), gastroesophageal reflux disease (9.1%), age >14 years (9.1%), and low BMI (9.1%) were most commonly associated with AP. Two deaths (0.6%) were reported.
CONCLUSION
AP remains an important complication of spinal surgery because of its morbidity and mortality. Avoiding major risk factors can reduce the incidence of AP following spinal surgery.

Meta-Analysis Review
OBJECTIVE
To explore the value of magnetic resonance imaging (MRI) in fetuses with periventricular pseudocysts (PVPC) and the neurodevelopmental outcomes of these fetuses via meta-analysis.
METHODS
MEDLINE and EMBASE database were searched for studies reporting on the MRI assessment of fetuses diagnosed with PVPC on neurosonography. The neurosonography was conducted according to the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) guidelines or standard axial, coronal and sagittal planes for advanced central nervous system (CNS) assessment. Single-shot fast spin-echo T2-weighted sequences of MRI technique in three orthogonal planes were necessarily performed. The pooled proportion of CNS anomalies missed on neurosonography and detected only at prenatal MRI was calculated. Subanalysis was performed according to the types of intracranial anomalies. The pregnancy outcomes (including normal, abnormal, termination of pregnancy, and perinatal death) of PVPC fetuses were also analyzed.
RESULTS
Five studies comprising 136 fetuses were included in this meta-analysis. Mean gestational age was 29.8 weeks (16-38 weeks) at ultrasonography and 31.5 weeks (25-37 weeks) at MRI. Overall, MRI detected exclusively CNS anomalies in 25.2% (95% CI 15.9-35.8%) of cases. Among them, the highest incidence was white matter abnormalities with the pooled proportion of 16.3% (95% CI 9.7-24.2%). When getting rid of white matter abnormalities, the risk of associated CNS anomalies only detected on MRI was reduced to 9.1% (95% CI 1.8-21.4%). Meanwhile, 130 cases were studied to assess the pregnancy outcomes with the scope of 1 month to 10 years. The pooled proportion of normal outcomes in isolated PVPC fetuses was as high as 95.0% (95% CI 83.9-99.8%). When analyzing the neurodevelopmental outcomes in non-isolated PVPC fetuses, the incidence of normal neurodevelopmental outcomes was about 22.1% (95% CI 5.6-45.5%) with mild and single additional abnormalities, the rate of abnormal neurodevelopmental outcomes was 19.5% (95% CI 11.0-29.7%) with apparent and/or multiple abnormalities. Besides, 53.6% (95% CI 35.4-71.3%) of non-isolated PVPC cases were terminated mainly due to infections, genetic anomalies, metabolic disorders and hemorrhage.
CONCLUSIONS
MRI assessment of PVPC fetuses is recommended to detect associated intracranial anomalies that may be missed on dedicated neurosonography. White matter abnormalities on MRI account for the majority of additional anomalies, which might to be the clue of CMV infection, aminoacidopathy or white matter disease. Moreover, the neurodevelopmental outcome of isolated PVPC fetuses remains favorable, while the neurodevelopmental outcomes of non-isolated PVPC fetuses depend on the accompanying anomaly.

PURPOSE
Endoscopic drainage is an established treatment modality for adult patients with pancreatic fluid collections (PFCs). Available data regarding the efficacy and safety of endoscopic drainage in pediatric patients are limited. In this systematic review and meta-analysis, we aimed to analyze the outcomes of endoscopic drainage in children with PFCs.
METHODS
A literature search was performed in Embase, PubMed, and Google Scholar for studies on the outcomes of endoscopic drainage with or without endoscopic ultrasonography (EUS) guidance in pediatric patients with PFCs from inception to May 2021. The study's primary objective was clinical success, defined as resolution of PFCs. The secondary outcomes included technical success, adverse events, and recurrence rates.
RESULTS
Fourteen studies (187 children, 70.3% male) were included in this review. The subtypes of fluid collection included pseudocysts (60.3%) and walled-off necrosis (39.7%). The pooled technical success rates in studies where drainage of PFCs were performed with and without EUS guidance were 95.3% (95% confidence interval [CI], 89.6-98%; =0) and 93.9% (95% CI, 82.6-98%; =0), respectively. The pooled clinical success after one and two endoscopic interventions were 88.7% (95% CI, 82.7-92.9%; =0) and 92.3% (95% CI, 87.4-95.4%; =0), respectively. The pooled rate of major adverse events was 6.3% (95% CI, 3.3-11.4%; =0). The pooled rate of recurrent PFCs after endoscopic drainage was 10.4% (95% CI, 6.1-17.1%; =0).
CONCLUSION
Endoscopic drainage is safe and effective in children with PFCs. However, future studies are required to compare endoscopic and EUS-guided drainage of PFCs in children.

Urgent Endoscopic Retrograde Cholangiopancreatography (ERCP) vs. Conventional Approach in Acute Biliary Pancreatitis Without Cholangitis: An Updated Systematic Review and Meta-Analysis.
Gallstone disease is the common cause of acute pancreatitis. The role of early endoscopic retrograde cholangiopancreatography (ERCP) in biliary pancreatitis without cholangitis is not well-established. Thus, this study aims to compare the outcome of early ERCP with conservative management in patients with acute biliary pancreatitis without acute cholangitis. An online search of PubMed, PubMed Central, Embase, Scopus, and Clinicaltrials.gov databases was performed for relevant studies published till December 15, 2020. Statistical analysis was performed using RevMan v 5.4 (The Nordic Cochrane Centre, Cochrane Collaboration, Copenhagen). Odds Ratio (OR) with a 95% confidence interval was used for outcome estimation. Among 2700 studies from the database search, we included four studies in the final analysis. Pooling of data showed no significant reduction in mortality (OR 0.59, 95% CI 0.32 to 1.09; p=0.09); overall complications (OR 0.56, 95% CI 0.30 to 1.01; p=0.05); new-onset organ failure (OR 1.06, 95% CI 0.65 to 1.75; p=0.81); pancreatic necrosis (OR 0.80, 95% CI 0.49 to 1.32; p=0.38); pancreatic pseudo-cyst (OR 0.44, 95% CI 0.16 to 1.24; p=0.12); ICU admission (OR 1.64, 95% CI 0.97 to 2.77; p=0.06); and pneumonia development (OR 0.81, 95% CI 0.40 to 1.65; p=0.56) by urgent ERCP comparing with conventional approach for acute biliary pancreatitis without cholangitis. Henceforth, early ERCP in acute biliary pancreatitis without cholangitis did not reduce mortality, complications, and other adverse outcomes compared to the conservative treatment.

Adrenal cysts are rare, benign, and usually asymptomatic, being detected as an incidental finding on imaging methods. Adrenal Cysts of Lymphatic Origin (ACLO) and Adrenal Lymphangiomas (AL) are types of endothelial cyst and are the most prevalent subtype in this series. This study aims to present a single institutional experience of these rare cysts and compare their features with those found in the review of existing literature on ACLO and AL. Overall, thirteen cases of adrenal cysts were diagnosed and surgically excised during the study period, onto which we performed immunohistochemistry using a panel of antibodies (CD31, CD34, Pan Cytokeratin AE-1/AE-3, Factor VII, D2-40, and ERG). Four cases of ACLO and two AL were found. The lesions predominantly affected right adrenal, and the majority of patients were middle-age females, of Caucasian ethnicity, and asymptomatic. In our literature review, we found 108 cases of ACLO/AL from 57 articles with similar sex and age distribution. The diagnosis and subclassification of adrenal cysts are challenging, and there is a significant overlapping between the definition of ACLO and AL.

Meta-Analysis
BACKGROUND
The effectiveness of prophylactic antibiotics in severe acute pancreatitis (SAP) remains a debatable issue. This meta-analysis aimed to determine the efficacy of prophylactic carbapenem antibiotics in SAP.
METHODS
This meta-analysis of prophylactic carbapenem antibiotics for SAP was conducted in PubMed, EMBASE, Web of Science, MEDLINE, and Cochrane Library up to February 2021. The related bibliographies were manually searched. The primary outcomes involved infected pancreatic or peripancreatic necrosis, mortality, complications, infections, and organ failure.
RESULTS
Seven articles comprised 5 randomized controlled trials and 2 retrospective observational studies, including 3,864 SAP participants. Prophylactic carbapenem antibiotics in SAP were associated with a statistically significant reduction in the incidence of infections (odds ratio [OR]: 0.27; p = 0.03) and complications (OR: 0.48; p = 0.009). Nevertheless, no statistically significant difference was demonstrated in the incidence of infected pancreatic or peripancreatic necrosis (OR: 0.74; p = 0.24), mortality (OR: 0.69; p = 0.17), extrapancreatic infection (OR: 0.64, p = 0.54), pulmonary infection (OR: 1.23; p = 0.69), blood infection (OR: 0.60; p = 0.35), urinary tract infection (OR: 0.97; p = 0.97), pancreatic pseudocyst (OR: 0.59; p = 0.28), fluid collection (OR: 0.91; p = 0.76), organ failure (OR: 0.63; p = 0.19), acute respiratory distress syndrome (OR: 0.80; p = 0.61), surgical intervention (OR: 0.97; p = 0.93), dialysis (OR: 2.34; p = 0.57), use of respirator or ventilator (OR: 1.90; p = 0.40), intensive care unit treatment (OR: 2.97; p = 0.18), and additional antibiotics (OR: 0.59; p = 0.28) between the experimental and control groups.
CONCLUSIONS
It is not recommended to administer routine prophylactic carbapenem antibiotics in SAP.

Review
There are case reports and small case series in the literature reporting gas-filled pseudocysts (GFP). However, a systematic review presenting overall view of the disease and its management is still lacking. In the present study, we aimed to make a systematic review of GFP cases, and present an exemplary case of ours. Our second aim was to discuss current theories for pathogenesis of GFP. A systematic review of GFP was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Two large-scaled data search engines were used. A total of 53 articles were retrieved from the literature and presented with an exemplary case of ours. Mean age of the historical cohort was 59.47 years. There were 66 male (54.1%) and 56 female (45.9%) patients. The most prevalent clinical presentation was radicular sign/symptom in lower limbs with (29.1%) or without low back pain (LBP) (67%). Gas-filled pseudocyst has most commonly been diagnosed at the lower lumbar spine (L4-L5, 45.3%; L5-S1, 37.7%). Surgery was the treatment of choice in most of the patients (80%). In the whole cohort, 79.1% of the patients had complete recovery. Gas-filled pseudocysts are rarely observed in daily practice. They present mostly in men at the age of 60s. Precise differential diagnosis determination using appropriate imaging would help clinicians treat the patients properly. Gas-filled pseudocysts should be treated similarly to other spinal pathologies causing nerve root compression.

Meta-Analysis
PURPOSE
The main goal of this systematic review was to assess the technical and clinical success, adverse events (AEs), surgery, and overall mortality proportion after percutaneous catheter drainage (PCD) of two pancreatic lesions.
METHODS
An extant search in online databases including Scopus, PubMed (Medline), Embase (Elsevier), Web of Science, Cochrane library, and Google Scholar, was conducted to recognize all studies that used PCD intervention in the management of pancreatic necrosis (PN) and pancreatic pseudocysts (PP). Random effects meta-analysis was performed, and Cochrane's Q test and Istatistic were utilized to determine heterogeneity. In addition, meta-regression was used to explore the influence of categorical variables on heterogeneity.
RESULTS
Thirty-two studies (1398 patients) including PN in 26 (1256 cases, 89.8%) studies and PP in 6 (142 cases, 10.2%) studies were identified. Technical success proportion was 100% (95% confidence interval [CI] 100%-100%, I: 0.0%), clinical success 63% (95% CI 55%-71%, I: 92.9%), AEs 26% (95% CI 21%-31%, I: 78%), surgery after PCD intervention 33% (95% CI 25%-40%, I: 92.4%), and overall mortality was 13% (95% CI 9%-17%, I: 82.8%). The most common ADs after PCD intervention were development of fistula (106, 42.6%), hemorrhage (44, 17.7%), sepsis (40, 16.1%).
CONCLUSION
A significant clinical success proportion with low AEs, surgery, and overall mortality proportion after PCD intervention was found, although the results should be interpreted with caution due to the high heterogeneity.

Meta-Analysis Review
BACKGROUND
Disconnected pancreatic duct syndrome (DPDS) frequently occurs in patients with acute necrotizing pancreatitis and resultant pancreatic fluid collection (PFC). We performed a systematic review and meta-analysis to evaluate outcomes of endoscopic ultrasound-guided treatment of PFCs according to the presence of DPDS.
METHODS
Using PubMed, Embase, and the Cochrane database, we identified clinical studies published until January 2021 with data comparing outcomes of endoscopic ultrasound-guided drainage of PFCs between DPDS and non-DPDS patients. We pooled data on technical and clinical success rates, PFC recurrence, and adverse events using the random-effects model.
RESULTS
We identified five eligible articles including 941 PFC patients treated with endoscopic ultrasound-guided interventions. Clinical success, defined as resolution of the PFC and symptoms, was achieved in a majority of the cases irrespective of DPDS (pooled odds ratio [OR] comparing DPDS to non-DPDS patients, 0.77; 95% confidence interval [CI] 0.33-1.81). Compared to patients without DPDS, patients with DPDS were more likely to undergo PFC recurrence (pooled OR 6.72; 95% CI 2.72-16.6) after clinical resolution of PFC. Prolonged plastic stent placement following the clinical resolution was more frequently performed in DPDS patients than in non-DPDS patients (pooled OR 15.9; 95% CI 2.76-91.9). No statistically significant difference was observed between the groups in terms of the rate of technical success, adverse events, or mortality.
CONCLUSION
Disconnected pancreatic duct syndrome was associated with higher rate of PFC recurrence after successful endoscopic treatment of PFCs. Future studies should evaluate effectiveness and optimal duration of long-term placement of transmural plastic stents for PFCs with DPDS.
