Meta-Analysis
OBJECTIVES
Vascular rings may cause tracheal and/or oesophageal compression. For many patients, symptoms/signs have been present for a long period before diagnosis. However, in the era of prenatal diagnosis, some units advocate universal early surgery. The risks and efficacy of surgery must be known to adequately counsel for the operation. This meta-analysis sought to define the morbidity and mortality associated with surgical correction, and persistent post-operative symptoms.
METHODS
PubMed, Cochrane Library and CINAHL databases were searched for studies that described the outcome of patients undergoing surgery for a double or right aortic arch (DAA or RAA). Non-comparative and random effects model-based meta-analyses were conducted to calculate the pooled rates of mortality, surgical complications, reintervention, and persistent follow-up symptoms.
RESULTS
Nineteen eligible studies were included comprising 18 studies describing outcomes for DAA surgery and 15 for RAA surgery. For DAA surgery, overall mortality rate was 0% [95% confidence interval (CI) 0.0-1.0], post-surgical complication rate 18% [95% CI: 12.0-23.0], prevalence of reintervention 3% [95% CI: 1.0-5.0] and prevalence of symptoms at last follow-up was 33% [95% CI: 17.0-52.0]. For RAA surgery, overall pooled mortality was 0% [95% CI: 0.0-0.0], prevalence of post-surgical complications was 15% [95% CI: 8.0-23.0], reintervention rate was 2% [95% CI: 0.0-4.0], prevalence of symptoms at last follow-up was 40% [95% CI: 26.0-55.0].
CONCLUSIONS
While surgery to correct a vascular ring is safe, the rate of persistent symptoms is high and further strategies must be sought to reduce this burden.

Meta-Analysis
In the last decade, flexible endoscopic septotomy has been reported as a well-tolerated and effective treatment for Zenker's diverticulum. More recently, novel endoscopic submucosal tunneling techniques, namely Zenker-PerOral Endoscopic Myotomy (Z-POEM) and PerOral Endoscopic Septotomy (POES) have been proposed to obtain complete muscular septum exposure and deeper myotomy. The aim of this study is to provide a systematic review with a meta-analysis of the first experiences of third space approaches for Zenker's diverticulum. Electronic databases (Medline, Scopus, EMBASE) were searched up to October 2020. Studies including patients with symptomatic Zenker's diverticulum who underwent endoscopic treatment by submucosal tunneling technique were eligible. Procedural, clinical and safety outcomes were assessed by pooling data with a random-effect model to obtain a proportion with a 95% confidence interval. Nine retrospective studies were eligible for inclusion (196 patients). Five studies were performed in the USA, two in Europe and two in Asia. Endoscopic treatment was feasible in 96.9% (I2 = 0%) of patients. The mean procedure duration was 36.4 ± 14.3 minutes. Clinical success was achieved after 93.4% (I2 = 0%) of procedures. The overall adverse events rate was 4.9% (I2 = 0%). No differences between the two approaches (Z-POEM vs POES) have been shown in terms of both efficacy and safety. Submucosal tunneling techniques appear to be feasible for symptomatic Zenker's diverticulum, with promising results in terms of efficacy and safety outcomes.

Meta-Analysis
Esophageal diverticula can cause significant symptoms and affect the quality of life. There has been recent interest in the use of peroral endoscopic myotomy in the management of esophageal diverticula (D-POEM). In this meta-analysis, we have evaluated the efficacy and safety of D-POEM in the management of esophageal diverticula. Several databases were reviewed from inception to 6/19/2020 to identify the studies evaluating the feasibility, efficacy and safety of D-POEM in the management of esophageal diverticula. Our outcomes of interest were technical success, adverse events and difference in mean pre- and post-procedure symptom score. We performed subgroup analysis including patients with Zenker's diverticulum who underwent POEM (Z-POEM). Pooled rates with 95% confidence intervals (CI) for all outcomes were calculated using random effect model. We calculated standard mean difference (SMD) with 95% CI to compare mean pre- and post-procedure symptom score. We included 7 studies with 233 patients. For D-POEM, pooled rates (95% CI) for technical success and adverse events were 95% (91%, 97%) and 6% (3%, 10%) respectively. For Z-POEM, pooled rates (95% CI) for technical success and adverse events were 95% (90%, 97%) and 6% (3%, 10%) respectively. Mean post-procedure symptom score for all patients who underwent D-POEM was significantly lower compared to mean pre-procedure symptom score, SMD (95% CI) 2.17 (1.51, 2.83). This meta-analysis demonstrated that D-POEM is a safe and feasible option for patients with symptomatic esophageal diverticula.

Meta-Analysis
BACKGROUND
There is limited evidence on the efficacy of peroral endoscopic myotomy (POEM) in patients with esophageal diverticula.
AIMS
This meta-analysis aimed to assess the efficacy and safety profile of POEM in patients with Zenker (ZD) and epiphrenic diverticula.
METHODS
With a literature search through August 2020, we identified 12 studies (300 patients) assessing POEM in patients with esophageal diverticula. The primary outcome was treatment success. Results were expressed as pooled rates and 95% confidence intervals.
RESULTS
Pooled rate of technical success was 95.9% (93.4%-98.3%) in ZD patients and 95.1% (88.8%-100%) in patients with epiphrenic diverticula. Pooled rate of treatment success was similar for ZD (90.6%, 87.1%-94.1%) and epiphrenic diverticula (94.2%, 87.3%-100%). Rates of treatment success were maintained at 1 year (90%, 86.4%-97.4%) and 2 years (89.6%, 82.2%-96.9%) in ZD patients. Pooled rate of symptom recurrence was 2.6% (0.9%-4.4%) in ZD patients and 0% in patients with epiphrenic diverticula. Pooled rates of adverse events and severe adverse events were 10.6% (4.6%-16.6%) and 3.5% (0%-7.4%) in ZD and 8.4% (0%-16.8%) and 8.4% (0%-16.8%) in epiphrenic diverticula, respectively.
CONCLUSION
POEM represents an effective and safe therapy for the treatment of esophageal diverticula.

BACKGROUND
The best treatment for perforated colonic diverticulitis with generalized peritonitis is still under debate. Concurrent strategies are resection with primary anastomosis (PRA) with or without diverting ileostomy (DI), Hartmann's procedure (HP), laparoscopic lavage (LL) and damage control surgery (DCS). This review intends to systematically analyze the current literature on DCS.
METHODS
DCS consists of two stages. Emergency surgery: limited resection of the diseased colon, oral and aboral closure, lavage, vacuum-assisted abdominal closure. Second look surgery after 24-48 h: definite reconstruction with colorectal anastomosis (-/ + DI) or HP after adequate resuscitation. The review was conducted in accordance to the PRISMA-P Statement. PubMed/MEDLINE, Cochrane central register of controlled trials (CENTRAL) and EMBASE were searched using the following term: (Damage control surgery) AND (Diverticulitis OR Diverticulum OR Peritonitis).
RESULTS
Eight retrospective studies including 256 patients met the inclusion criteria. No randomized trial was available. 67% of the included patients had purulent, 30% feculent peritonitis. In 3% Hinchey stage II diverticulitis was found. In 49% the Mannheim peritonitis index (MPI) was greater than 26. Colorectal anastomosis was constructed during the course of the second surgery in 73%. In 15% of the latter DI was applied. The remaining 27% received HP. Postoperative mortality was 9%, morbidity 31% respectively. The anastomotic leak rate was 13%. 55% of patients were discharged without a stoma.
CONCLUSION
DCS is a safe technique for the treatment of acute perforated diverticulitis with generalized peritonitis, allowing a high rate of colorectal anastomosis and stoma-free hospital discharge in more than half of the patients.

BACKGROUND
While necrotizing enterocolitis (NEC) is a prevalent condition in preterm neonates admitted to neonatal intensive care unit (NICU), intussusception is exceedingly uncommon and often overlooked. This is due to the fact that they share many clinical characteristics. The initial misdiagnosis of intussusception in preterm neonates (IPN) especially has led to a delay in their management, which increases the risk of developing compromised bowel. Additionally, it is difficult to reach a diagnosis as neonatal intussusception does not have any classical radiological signs even when contrast enema is used. This systematic review is based on the published literature including case reports and case series to review the clinical features of IPN and how to differentiate it from NEC in order to shed the light on this rare disease and how having a high index of suspicion would help practitioners to make an early and accurate diagnosis METHODS: A systematic literature search to report all cases of relevant articles that reported IPN till date. All cases that were born before 37 weeks gestational age, presented within the neonatal period and having well established documentation were included in the study. Any case that did not have these criteria was excluded from our study.
RESULTS
Only 52 cases met these criteria during the period from 1963 till date. An average of 10 days had elapsed before the cases were confirmed to have IPN either clinically or intraoperatively. The most frequent manifestations were abdominal distension and bilious gastric residuals, occurring in 85% and 77% of the cases respectively, followed by bloody stools in 43% of cases. However, this triad was present only in approximately one-third of the cases. Only 13 cases were diagnosed as having intussusception preoperatively. About two thirds of the intussusception were located in the ileum. Pathological lead point was present in 7 cases only; 4 of them were due to Meckel's diverticulum. Nine cases only out of the 52 cases with IPN died.
CONCLUSION
It is crucial to detect the clues for diagnosis of intussusception because in contrast to NEC, it is unresponsive to conservative management, affects the viability of the bowel and surgery is essential.

BACKGROUND
The perforated duodenal diverticulum remains a rare clinical entity, the optimal management of which has not been well established. Historically, primary surgery has been the preferred treatment modality. This was called into question during the last decade, with the successful application of non-operative therapy in selected patients. The aim of this systematic review is to identify cases of perforated duodenal diverticula published over the past decade and to assess any subsequent evolution in treatment.
METHODS
A systematic review of English and non-English articles reporting on perforated duodenal diverticula using MEDLINE (2008-2020) was performed. Only cases of perforated duodenal diverticula in adults (> 18 years) that reported on diagnosis and treatment were included.
RESULTS
Some 328 studies were identified, of which 31 articles met the inclusion criteria. These studies included a total of 47 patients with perforated duodenal diverticula. This series suggests a trend towards conservative management with 34% (16/47) of patients managed non-operatively. In 31% (5/16) patients initially managed conservatively, a step-up approach to surgical intervention was required.
CONCLUSION
Conservative treatment of perforated duodenal diverticula appears to be an acceptable and safe treatment strategy in stable patients without signs of peritonitis under careful observation. For patients who fail to respond to conservative treatment, a step-up approach to percutaneous drainage or surgery can be applied. If surgery is required, competence in techniques ranging from simple diverticulectomy to Roux-en-Y gastric diversion or even Whipple's procedure may be required depending on tissue friability and diverticular collar size.

Comparative Study Meta-Analysis
Most Zenker's diverticula (ZD) cohort studies are single-institution retrospective observational studies of recurrence rates. There is a gap in the literature regarding patient-reported outcomes after ZD surgery. This study was conducted to compare if open transcervical diverticulectomy (OD) is better than endoscopic laser diverticulectomy (ELD) or endoscopic stapler-assisted diverticulectomy (ESD). The study design is of systematic review and meta-analysis. The following databases were searched: SCOPUS, EMBASE, PubMed, and Word of Science through December 2017. The quality of the studies was evaluated using 22-item STROBE checklist with 3 independent physician reviewers. The Inter-rater reliability was calculated both as a percent and utilizing Cohen's Kappa. For the meta-analysis, Cohen's d for an effect size was calculated for all studies comparing dysphagia results before and after surgery. A total of 865 patients were treated across 11 selected publications, of which 106 patients were treated OD, 310 ELD, and 449 with an ESD approach. Patient-reported dysphagia outcomes were reported as Cohen's d (confidence interval): OD, ELD, and ESD were 1.31 (0.88, 1.74), 1.91 (1.62, 2.20), and 2.45 (2.04, 2.86), respectively. The pooled effect of all studies for dysphagia was 2.22 (1.85, 2.59) and regurgitation 2.20 (1.80, 2.59). We did not prove that OD has superior outcomes compared to ESD and ELD. Any method of surgical intervention yields a large effect (i.e., improvement in dysphagia and regurgitation) comparing patient-reported symptoms before and after surgery. Future research, currently underway, includes a prospective, multi-institutional study comparing standardized outcomes between treatments of ZD including symptom resolution, complications, and recurrences using validated measures to define long-term outcomes.Level of Evidence 3.

Kommerell diverticulum (KD) combined with right-sided aortic arch (RAA) and aberrant left subclavian artery (ALSA) are rare and limited to a few case reports and small series. Thoracic endovascular aortic repair (TEVAR), which is mini-invasive, is widely utilized in complicated aortic disease. We performed a systematic review of the literature to identify all patients who underwent endovascular repair for KD in terms of technical feasibility and procedural outcomes. Published and accepted studies only in English as well as article reference lists were searched and extracted to assess case series reporting solely TEVAR in KD patients. There were 28 patients with KD/RAA identified from 19 studies. All of them underwent endovascular technique for KD exclusion and the median age was 69 years (range 39-83 years). Hypertension (n=17) was the most common comorbidity in this cohort, followed by diabetes mellitus (n=3), hyperlipidemia (n=3), and smoking (n=3). The presenting symptoms were dysphagia (n=8, 29%), intermittent back pain (n=4, 14%), and acute aortic dissection (n=6, 21%), while asymptomatic was found in 9 patients (n=9, 32%). A technical success rate of 100% was reported associated with various managements of ALSA, proximal embolization (n=19, 68%), in-situ revascularization (n=3, 11%), and left carotid-subclavian bypass (n=3, 11%). All patients survived without severe complications and were discharged home within less than 14 days. The mean follow-up time was 9.3 months, patency was found in all patients, thrombosis and distinct shrinkage of KD aneurysm as indicated by CT-scans were noted (n=20, 71%), and type II endoleak was found in only 4 patients (n=4, 14%). TEVAR appears to be safe and offers favorable results, but it still needs substantial evidence to support routine use in KD. TEVAR is an alternative to open repair in selected cases, but it needs further investigation in a large cohort.

Meta-Analysis
OBJECTIVE
This network meta-analysis compared treatment via laparoscopy, hysteroscopy (HP), combined laparoscopy with HP (LH), and vaginal repair (VR) for reducing intermittent abnormal uterine bleeding and cesarean scar defect (CSD) diverticulum depth in patients with CSD.
DATA SOURCES
Electronic databases (PubMed, EMBASE, The Cochrane Central Register of Controlled Trials, MEDLINE, ClinicalTrials.gov, Chinese Biomedical Literature Database, and China National Knowledge Integrated) were searched for articles published through June 13, 2018.
METHODS OF STUDY SELECTION
The search included randomized controlled trials (RCTs) and observational studies of surgical treatment for CSD. Standardized mean difference (SMD) and 95% confidence intervals (CIs) were reported. RCTs were evaluated by the Cochrane risk-of-bias tool, observational studies by Risk of Bias in Nonrandomized Studies of Intervention, and overall evidence quality by grade. Data were analyzed by STATA (version 15.0; StataCorp, College Station, TX) and R software for windows (version 3.5.0; R Core Team, 2018).
TABULATION, INTEGRATION, AND RESULTS
Ten studies (n = 858; 4 RCTs and 6 observational studies) were included. Patients who underwent uterine diverticulum resection by LH had a shorter duration of abnormal uterine bleeding than those by HP (SMD = 1.36, 95% CI, 0.37-2.36; p = .007) and VR (SMD = 1.58, 95% CI, 0.97-2.19; p <.0001). LH reduced the CSD diverticulum depth more than VR (SMD = 1.57, 95% CI, 0.54-2.61; p = .003). There was no significant difference in efficacy among the surgical procedures.
CONCLUSION
LH reduced intermittent abnormal uterine bleeding and scar depth more than the other surgical interventions. Larger clinical trials are warranted to verify this analysis.
