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.

Review
BACKGROUND
Groove pancreatitis (GP) is a focal form of chronic pancreatitis affecting the paraduodenal groove area, for which consensus on diagnosis and management is lacking.
GOALS
We performed a systematic review of the literature to determine patient characteristics and imaging features of GP and to evaluate clinical outcomes after treatment.
RESULTS
Eight studies were included reporting on 335 GP patients with a median age of 47 years (range, 34 to 64 y), with 90% male, 87% smokers, and 87% alcohol consumption, and 47 months (range, 15 to 122 mo) of follow-up. Most patients presented with abdominal pain (91%) and/or weight loss (78%). Imaging frequently showed cystic lesions (91%) and duodenal stenosis (60%).Final treatment was conservative (eg, pain medication) in 29% of patients. Endoscopic treatment (eg, pseudocyst drainage) was applied in 19% of patients-34% of these patients were subsequently referred for surgery. Overall, 59% of patients were treated surgically (eg, pancreatoduodenectomy). Complete symptom relief was observed in 50% of patients who were treated conservatively, 57% who underwent endoscopic treatment, and 79% who underwent surgery.
CONCLUSIONS
GP is associated with male gender, smoking, and alcohol consumption. The vast majority of patients presents with abdominal pain and with cystic lesions on imaging. Although surgical treatment seems to be the most effective, both conservative and endoscopic treatment are successful in about half of patients. A stepwise treatment algorithm starting with the least invasive treatment options seems advisable.

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.

Review
BACKGROUND
The laparoscopic and endoscopic approaches to internal drainage of pancreatic pseudocysts (PPs) are the current minimally invasive management options. This article reviews the evidence available on their effectiveness.
METHODS
A computerized search was made of the MEDLINE, PubMed, and EMBASE databases for English language publications from 1974 to 2005.
RESULTS
A total of 118 and 569 patients featured, respectively, in 19 and 25 reports underwent 118 and 583 laparoscopic and endoscopic drainage procedures, respectively. Pancreatic pseudocysts were considerably larger in the laparoscopic series (mean, 13 vs. 7 cm; p < 0.0001). The success rates for achieving resolution of the PPs in the laparoscopic and endoscopic series were 98.3% and 80.8% respectively, with morbidity rates of 4.2% and 12% and mortality rates of 0% and 0.4%, respectively. During follow-up period (mean, 13 vs 24 months; p < 0.0001), PPs recurred for 2.5% of the patients in the laparoscopic series and 14.4% of the patients in the endoscopic series, and the reintervention rates were 0.9% and 11.8%, respectively.
CONCLUSIONS
The laparoscopic and endoscopic approaches to internal drainage of PPs are safe. Although laparoscopic drainage appears to carry a higher success rate and lower rates of morbidity and recurrence, the heterogeneity of the published reports and the varied follow-up periods limit direct comparisons. Data from longer follow-up periods and randomized comparative trials are needed.

Meta-Analysis
PURPOSE
To describe the postnatal outcome of fetal meconium peritonitis and identify prenatal predictors of neonatal surgery.
METHODS
We retrospectively reviewed all fetuses with ultrasound findings suspicious for meconium peritonitis at a single center over a 10-year period. A systematic review and meta-analysis were then performed pooling our results with previous studies assessing prenatally diagnosed meconium peritonitis and postnatal outcome. Prenatal sonographic findings were analyzed to identify predictors for postnatal surgery.
RESULTS
34 cases suggestive of meconium peritonitis were diagnosed at our center. These were pooled with cases from 14 other studies yielding a total of 244 cases. Postnatal abdominal surgery was required in two thirds of case (66.5 %). The strongest predictor of neonatal surgery was meconium pseudocyst (OR [95 % CI] 6.75 [2.53-18.01]), followed by bowel dilation (OR [95 % CI] 4.17 [1.93-9.05]) and ascites (OR [95 % CI] 2.57 [1.07-5.24]). The most common cause of intestinal perforation and meconium peritonitis, found in 52.2 % of the cases, was small bowel atresia. Cystic fibrosis was diagnosed in 9.8 % of cases. Short-term neonatal outcomes were favorable, with a post-operative mortality rate of 8.1 % and a survival rate of 100 % in neonates not requiring surgery.
CONCLUSION
Meconium pseudocysts, bowel dilation, and ascites are prenatal predictors of neonatal surgery in cases of meconium peritonitis. Fetuses with these findings should be delivered in centers with pediatric surgery services. Though the prognosis is favorable, cystic fibrosis complicates postnatal outcomes.

Meta-Analysis
OBJECTIVE
This systematic review and meta-analysis aims to compare surgical and endoscopic treatment for pancreatic pseudocyst (PP).
METHODS
The researchers did a search in Medline, EMBASE, Scielo/Lilacs, and Cochrane electronic databases for studies comparing surgical and endoscopic drainage of PP s in adult patients. Then, the extracted data were used to perform a meta-analysis. The outcomes were therapeutic success, drainage-related adverse events, general adverse events, recurrence rate, cost, and time of hospitalization.
RESULTS
There was no significant difference between treatment success rate (risk difference [RD] -0.09; 95% confidence interval [CI] [0.20,0.01]; P = .07), drainage-related adverse events (RD -0.02; 95% CI [-0.04,0.08]; P = .48), general adverse events (RD -0.05; 95% CI [-0.12, 0.02]; P = .13) and recurrence (RD: 0.02; 95% CI [-0.04,0.07]; P = .58) between surgical and endoscopic treatment.Regarding time of hospitalization, the endoscopic group had better results (RD: -4.23; 95% CI [-5.18, -3.29]; P < .00001). When it comes to treatment cost, the endoscopic arm also had better outcomes (RD: -4.68; 95% CI [-5.43,-3.94]; P < .00001).
CONCLUSION
There is no significant difference between surgical and endoscopic treatment success rates, adverse events and recurrence for PP. However, time of hospitalization and treatment costs were lower in the endoscopic group.

Diagnostic accuracy of EUS-guided through-the-needle-biopsies and simultaneously obtained fine needle aspiration for cytology from pancreatic cysts: A systematic review and meta-analysis.
OBJECTIVES
To address the diagnostic accuracy of endoscopic ultrasound guided through-the-needle-biopsies (TTNBs) and simultaneously obtained cytology samples from pancreatic cysts compared to the final histopathological diagnosis of the surgical specimen, and to give an overview of ancillary tests performed on TTNBs.
METHODS
A literature search was conducted in MEDLINE, Embase and Scopus. Studies were included in the meta-analysis, if they had data for TTNB, cytology and a surgical specimen of pancreatic cysts as reference standard. The assessment of the risk of bias and quality of the included studies was conducted using the modified QUADAS-2 tool.
RESULTS
Ten studies with 99 patients were included in the meta-analysis. Data regarding study design and clinicopathological features were extracted systematically. For TTNB, pooled sensitivity was 0.86 (95 % CI 0.62-0.96), specificity 0.95 (95 % CI 0.79-0.99) and area under the curve (AUC) 0.86 for the diagnosis of a mucinous cyst and pooled sensitivity was 0.78 (95 % CI 0.61-0.89), specificity 0.99 (95 % CI 0.90-0.99) and AUC 0.92 for the diagnosis of a high-risk cyst. For a specific diagnosis, pooled sensitivity was 0.69 (95 % CI 0.50-0.83), specificity 0.47 (95 % CI 0.28-0.68) and AUC 0.49. For cytology performed simultaneously, pooled sensitivity was 0.46 (95 % CI 0.35-0.57), specificity 0.90 (95 % CI 0.46-0.99) and AUC 0.64 for the diagnosis of mucinous cysts, and pooled sensitivity was 0.38 (95 % CI 0.23-0.55), specificity 0.99 (95 % CI 0.90-0.99) and AUC 0.84 for the diagnosis of a high-risk cyst. For a specific diagnosis, pooled sensitivity was 0.29 (95 % CI 0.21-0.39), specificity 0.45 (95 % CI 0.25-0.66) and AUC 0.30. Furthermore, immunohistochemical stains can be useful to establish the specific cyst subtype.
CONCLUSIONS
TTNBs have a higher sensitivity and specificity than cytology for the diagnosis of mucinous cyst and high- risk cysts of the pancreas.

Meta-Analysis
AIM
Blunt abdominal trauma is the major cause of abdominal injury in children. No clear guidelines exist for the initial management of blunt pancreatic trauma in children. The aim of this study was to perform a systematic review and meta-analysis of initially non-operative versus initially operative treatment in children with blunt pancreatic injury.
METHODS
Studies including children (<18 years) with blunt pancreatic injuries published in any language after year 1990 were included. Total of 849 studies were identified by searching PubMed, Scopus, CINAHL and Cochrane Database. After review, 42 studies met inclusion criteria and were included in this systematic review. There were 1754 patients, of whom 1095 were initially managed non-operatively (NOM), and 659 operatively (OM). Primary outcome was non-operative management success rate, and secondary outcomes were mortality, complications (including specifically pseudocysts and pancreatic fistulas), percent of patients and days on total parenteral nutrition (TPN), length of hospital stay and readmissions.
RESULTS
There was no difference in mortality between NOM and OM groups. The incidence of pseudocysts was significantly higher in NOM group compared to OM (P<0.001), especially for AAST grade III or higher (P<0.00001). Overall incidence of pancreatic fistulas was significantly lower for NOM group (p = 0.02) but no difference was observed for AAST grades III or higher (p = 0.49). There was no difference in the length of hospital stay (P = 0.31). Duration of total parenteral nutrition was not different for all AAST grades (P = 0.35), but was significantly shorter for OM group for AAST grades III and higher (p = 0.0001). There was no overall difference in readmissions (P = 0.94). Overall success rate of initial non-operative treatment was 87%.
CONCLUSIONS
Most patients with pancreatic trauma can initially be treated non-operatively, while early surgical treatment may benefit patients with lesions of the main pancreatic duct. ERCP offers both highly accurate diagnosis and potential treatment of ductal injuries.

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.

Review
Ganglion cyst of the temporomandibular joint (TMJ) is an uncommon pathology with uncertain etiology. There is no consensus on their management. The current systematic review aimed to discuss the clinical and histopathological features of ganglion cysts of TMJ, to aid in appropriate treatment. A literature search was done and a total of 20 cases were retrieved from published databases such as PubMed, SCOPUS, and Google Scholar. The cyst presented with swelling in all the cases followed by pain (50 %) and trismus (35 %) as other common symptoms. Though CT and MRI proved helpful in determining the location of the cyst, a histopathological examination was essential in concluding its final diagnosis. It is a pseudocyst lined by dense fibro-connective tissue with myxoid tissue degeneration. Histologically, it is essential to distinguish them from the clinically and radiographically similar true cyst of TMJ, synovial cyst. The lining of ganglion cyst is devoid of epithelium and synovial cells. Surgical excision was found to be the treatment of choice with minimal recurrence (10 %) being reported.
