Meta-Analysis Review
The traditional way to tackle Zenker's diverticulum (ZD) has been flexible endoscopic septum division (FESD). Recently, the concept of per oral endoscopic myotomy has been found useful for managing diverticular diseases of the esophagus and has been termed DPOEM. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of D-POEM in diverticular disease of the esophagus and to compare it with FESD. We systematically searched PubMed and Embase, for studies reporting clinical success, technical success and adverse events in D-POEM alone or D-POEM comparing with FESD. We computed pooled prevalence for D-POEM alone and risk ratio for D-POEM vs FESD using random effect method with inverse variance approach. Subgroup analysis for ZD, non-ZD and mixed diverticulum was conducted. Totally 19 studies including 341 patients were identified reporting on D-POEM. The pooled clinical, technical success and adverse event rates for D-POEM were 87.07%, 95.19% and 10.22%, respectively. The clinical success was significantly better than FESD while the technical success, adverse event rate, procedure time and length of hospital stay were comparable with FESD. The recurrence rate was negligible for D-POEM compared to FESD. On subgroup analysis by dividing into three groups of ZD, non-ZD and mixed, there was no difference between clinical, technical success and adverse event rate among the three groups. D-POEM is an effective and safe technique among both ZD and non-ZD patients and has better clinical success than FESD.

Review
3D printing in adult cardiac and vascular surgery has been evaluated over the last 10 years, and all of the available literature reports benefits from the use of 3D models. In the present study, we analyzed the current applications of 3D printing for adult cardiovascular disease treated with surgical or catheter-based interventions, including the clinical medical simulation of physiological or pathology conducted with 3D printing in this field. A search of PubMed and MEDLINE databases were supplemented by searching through bibliographies of key articles. Thereafter, data on demographic, clinical scenarios and application, imaging modality, purposes of using with 3D printing, outcomes and follow-up were extracted. A total of 43 articles were deemed eligible and included. 296 patients (mean age: 65.4±14.2 years; male, 58.2%) received 3D printing for cardiac and vascular surgery or conditions [percutaneous left atrial appendage occlusion (LAAO), TAVR, mitral valve disease, aortic valve replacement, coronary artery abnormality, HOCM, aortic aneurysm and aortic dissection, Kommerell's diverticulum, primary cardiac tumor and ventricular aneurysm]. Eight papers reported the utility of 3D printing in the medical simulator and training fields. Most studies were conducted starting in 2014. Twenty-six was case report. The major scenario used with 3D printing technology was LAAO (50.3%) and followed by TAVR (17.6%). CT and echocardiography were two main imaging techniques that were used to generate 3D-printed heart models. All studies showed that 3D-printed models were helpful for preoperative planning, orientation, and medical teaching. The important finding is that 3D printing provides a unique patient-specific method to assess complex anatomy and is helpful for intraoperative orientation, decision-making, creating functional models, and teaching adult cardiac and vascular surgery, including catheter-based heart surgery.

Review
A pouch protruding into the wall of the left ventricle (LV) may be either a recess, cleft, diverticulum, or aneurysm. Being aware of these anomalies is essential to make accurate diagnosis and guide management decisions. Standard multimodality imaging of the heart enables detailed characterizations of LV fissures and outpouchings. They often present as an incidental finding on echocardiography, and the clinical significance can be difficult to address. We provide an overview of echocardiographic features of LV recess, cleft, diverticulum, pseudoaneurysms/aneurysms, and non-compaction based upon review of the literature as well as present some relevant clinical cases from our echocardiography labs.

INTRODUCTION
Meckel's diverticulum (MD) is the most common congenital malformation in the gastrointestinal tract. Limited up-to-date evidence is available regarding MD in pregnancy. We aim to review the available pertinent literature to help support clinical decision making and patient management in the future.
MATERIALS AND METHODS
The search term 'Meckel's diverticulum' was combined with 'pregnant' or 'pregnancy'. Database searches of EMBASE, Medline and PubMed were conducted. All papers published in English from 01/01/1990 to 01/01/2021 were included. Simple statistical analysis (t-test) was performed.
RESULTS
Twenty-seven cases were included. Average age = 26.9 years. Average gestation = 25.1 weeks. Occurrence: first trimester = 3.7%; second trimester = 48.1% and third trimester = 48.1%. Presenting symptoms: abdominal pain 88.9%; nausea/vomiting 59.3%; fever 18.5%; abdominal distension 18.5%; haematochezia 11.1%; constipation 11.1%; haematemesis 3.7%, diarrhoea 3.7% and asymptomatic 3.7%. Mean duration of preceding symptoms = 3.4 days. Diagnostic imaging modalities utilised: ultrasound = 40.7%; CT = 25.9%; MRI = 14.8%; abdominal X-ray = 11.1% and endoscopy = 7.4%. All cases required definite surgical management: laparotomy = 65.4%; laparoscopy = 15.4%; C-section = 19.2% and unreported = 3.8%. Main intra-operative findings: perforated MD = 40.7%; intussusception with MD as a lead point = 11.1%; bleeding MD = 11.1%, inflamed MD = 11.1%; small bowel obstruction = 11.1%; gangrenous MD = 3.7%; volvulus = 3.7% and unspecified = 7.4%. Mean length from ileocolic junction = 51.7 cm. Average length of stay was 7.1 days. T-test (p-value = 0.12) when comparing management strategy. Three maternal complications and two foetal mortalities.
CONCLUSION
MD and associated pathology are difficult to diagnose in the pregnant cohort. Current imaging demonstrates low diagnostic accuracy and a deviation away from recognised nuclear medicine investigations. Surgery appears the definitive management with both open and laparoscopic approaches utilised. Significant maternal morbidity and foetal mortality are associated with this condition.

INTRODUCTION
Exomphalos with intestinal fistulation (EIF) is a rare variant of exomphalos with intestine opening to the surface of an intact sac, and may result in a diagnostic challenge. We report 3 new cases and conducted a systematic review of the literature, to characterize its association with the type of exomphalos and vitellointestinal duct (VI) as well as to evaluate its management and outcomes.
METHODS
A literature search from PubMed using keywords pertaining to exomphalos and fistulation was used to identify all unique cases reported between 1950 and 2020, in addition to the case series reported here, to establish the clinical presentation, histological findings, management and outcomes.
RESULTS
We found a total of 28 cases of EIF, of which 25 had been reported in 70 years from 19 reports. There was a male predominance (4-to-1 ratio). The majority presented as an exomphalos minor (n = 23, 82%) with a prolapsing patent VI duct (n = 16, 57%), most had evidence of Meckel's diverticulum (n = 25, 89%). All but one case were managed by fistula excision with or without ileal resection and anastomosis, followed by primary closure of the abdominal wall defect. All patients, except one with Trisomy 13 who received only palliative care, underwent surgery. Post-operative complications occurred in 7 patients (25%). Congenital anomalies were present in 12 (43%) and none had Beckwith-Wiedemann syndrome. Mortality occurred in 4 patients (14%) between 3 and 17 days. One EIF with exomphalos major failed early conservative treatment due to sac disintegration and sepsis, requiring staged closure, but had a good outcome.
DISCUSSION
EIF is a rare entity usually associated with exomphalos minor and vitelline duct involvement. EIF presentation is variable but primary surgery is the mainstay of treatment with generally good outcomes. Common features of EIF suggest a different embryopathogenesis to other forms of exomphalos.

OBJECTIVES
To report a recalcitrant spontaneous cerebrospinal fluid (CSF) fistula arising from multiple, anatomically-linked lateral skull base defects, and to review the available literature to determine optimal techniques for operative repair of congenital CSF fistulae.
METHODS
A patient with recurrent episodes of otologic meningitis was found to have a patent tympanomeningeal fissure, also known as a Hyrtl's fissure, and internal auditory canal (IAC) diverticulum that communicated with the jugular bulb. A systematic review of the literature characterized all reports of spontaneous congenital perilabyrinthine CSF leaks, and all cases of Hyrtl's fissures.
RESULTS
An 11-year-old female was referred for recurrent meningitis. Imaging demonstrated a fistulous connection between the middle ear and IAC diverticulum via the jugular foramen. Specifically, a Hyrtl's fissure was identified, as well as demineralized bone around the jugular bulb. Obliteration of the fissure was initially performed, and a fistula reformed 4 months later. Multifocal CSF egress in the hypotympanum was identified on re-exploration, and middle ear obliteration with external auditory canal (EAC) overclosure was performed. A systematic review of the literature demonstrated 19 cases of spontaneous congenital perilabyrinthine CSF leaks. In total, 6 cases had multiple sources of CSF leak and 2 had history suggestive of intracranial hypertension. All of these noted cases demonstrated leak recurrence. Middle ear obliteration with EAC overclosure was successful in 4 recalcitrant cases.
CONCLUSIONS
Repair of spontaneous congenital perilabyrinthine CSF leaks in cases demonstrating multiple sources of egress or signs of intracranial hypertension should be approached with caution. Middle ear obliteration with EAC overclosure may provide the most definitive management option for these patients, particularly if initial attempt at primary repair is unsuccessful.

Meta-Analysis Review
OBJECTIVE
A literature review and meta-analysis was performed to assess for difference in rate of complications and need for revision surgery between endoscopic stapler-assisted diverticulotomy and endoscopic carbon dioxide laser diverticulotomy. The hypothesis was that endoscopic stapler-assisted diverticulotomy has a lower complication rate but endoscopic carbon dioxide laser diverticulotomy has a lower need for revision surgery.
METHOD
This was a systematic review of English-language studies comparing endoscopic stapler-assisted diverticulotomy and endoscopic carbon dioxide laser diverticulotomy for the treatment of Zenker's diverticulum. Meta-analysis of results with regard to rate of pharyngeal perforation, major post-operative complication and need for re-operation was performed.
RESULTS
Nine retrospective studies were included with pooled analysis of 417 endoscopic stapler-assisted diverticulotomy and 413 endoscopic carbon dioxide laser diverticulotomy cases. Meta-analysis found no significant difference in rate of pharyngeal perforation, major complication or need for re-operation between the two groups.
CONCLUSION
This study demonstrated both endoscopic stapler-assisted diverticulotomy and endoscopic carbon dioxide laser diverticulotomy to be a safe alternative to open surgery for Zenker's diverticulum. Both appear to be similar in terms of adverse events and efficacy. The authors recommend either approach, guided by surgeon's preference and experience, where patients are unsuitable for an open surgery approach.

Review
Various management approaches have been developed to treat symptoms and prevent complications of the cesarean diverticulum. This systematic review aims to report the outcomes and fertility-related effects of hysteroscopy on women with myometrial scar defects after the cesarean section. Following the formulation of the patient/population, intervention, comparison, and outcomes (PICO) criteria, a systematic search was conducted on seven databases. Finally, a total of 18 studies were included for this systematic review and meta-analysis. All of the included patients suffered from post-cesarean section scars and presented with abnormal bleeding, pain, or secondary infertility. The overall pooled symptomatic improvement rate was 78.83% (95% CI: 72.46-85.76%); however, there was significant heterogeneity among the analyzed studies (I=87%; p-value: <0.001) and a significant risk of bias (p-value: <0.001). The overall resolution/improvement rate after adjusting for possible bias was higher, 92.82% (95% CI: 85.17-100%). The overall pregnancy rate was 69.77% (95% CI: 59.03-82.48%), while in the individual studies the rates varied, ranging from 25% to 80%. Nevertheless, there was moderate heterogeneity among the included studies (I=56%; p-value=0.011). In contrast, there was no significant risk of bias among the included studies (p-value=0.100). Furthermore, the meta-regression analyses did not show any significant effect of different follow-up durations on the overall effect size for both outcomes. In conclusion, there is still a need for high-quality, comparative studies with larger sample sizes and long-term follow-up periods to draw firm conclusions. Moreover, future studies should consider the minimum myometrial thickness that is sufficient to complete a healthy pregnancy.

Meta-Analysis Review
Non-steroidal anti-inflammatory drugs and acetylsalicylic acid increase the risk of complications of diverticular disease: a meta-analysis of case-control and cohort studies.
BACKGROUND
The role of non-steroidal anti-inflammatory drugs (NSAIDs) and acetylsalicylic acid in the occurrence of diverticular bleeding (DB), complicated diverticulitis (CD), and acute diverticulitis (AD) is not yet defined.
AIM
Update a systematic review and meta-analyses of case-control and cohort studies to evaluate the association between NSAIDs or acetylsalicylic acid with DB, CD, or AD.
METHODS
The study included were identified through MEDLINE, Scopus, Web of Science, and Cochrane Library databases. Sizes were pooled across studies to obtain the overall effect size. A random-effects model was used to account for different sources of variation among studies. Odds ratio (OR) with 95% confidence interval (CI) was used as a measure of effect size.
RESULTS
Thirteen studies were included in the systematic review and meta-analysis. NSAIDs and acetylsalicylic acid use were associated with an increased risk of DB (OR: 6.90, 95% CI 3.86 to 12.35, P ˂ 0.00001, and OR 2.84, 95% CI 2.19 to 3.67, P < 0.00001, respectively). NSAIDs and acetylsalicylic acid use were also associated with increased risk of CD occurrence (OR 3.13, 95% CI 1.73 to 5.68, P = 0.0002, and OR 1.49, 95% CI 1.02 to 2.17, P = 0.04, respectively). The only study found about AD occurrence showed that NSAIDs use was not associated with AD and acetylsalicylic acid use had a low risk of AD.
CONCLUSION
NSAIDs and acetylsalicylic acid significantly increase the risk of DB and CD. Further studies are needed to clarify the role of NSAIDs and acetylsalicylic acid in AD. However, increasing evidence suggests caution in the use of such medications in patients with colonic diverticula.

Meta-Analysis
IMPORTANCE
Zenker diverticulum (ZD) can cause significant dysphagia, and symptoms can return or persist after surgery. This systematic review and network meta-analysis is the first to our knowledge to compare 3 common surgical techniques for ZD.
OBJECTIVE
To compare the 3 most common surgical techniques-endoscopic laser-assisted diverticulotomy, endoscopic stapler-assisted diverticulotomy, and transcervical diverticulectomy with cricopharyngeal myotomy-in adult patients with ZD.
DATA SOURCES
The published literature was searched using strategies designed by a medical librarian (search performed September 21, 2018). Strategies were established using a combination of controlled vocabulary terms and keywords and were executed in Ovid MEDLINE (1946 to September 21, 2018), Embase (1947 to September 21, 2018), Scopus (1823 to September 21, 2018), Cochrane Library, and ClinicalTrials.gov. Results were limited to English using database-supplied filters, which generated studies from 1997 to 2017.
STUDY SELECTION
Inclusion criteria were cohort studies or randomized clinical trials. Studies that included patients needing revision surgery or undergoing an alternative technique were excluded.
DATA EXTRACTION AND SYNTHESIS
The Preferred Reporting Items for Systematic Reviews and Meta-analyses-Network Meta-analyses (PRISMA-NMA) checklist was used to report the study findings. Two authors independently reviewed the studies.
MAIN OUTCOME AND MEASURE
The primary outcome measure was the incidence of persistent or recurrent symptoms following surgery. The primary study outcome was planned before data collection began.
RESULTS
The search generated 529 studies. After applying inclusion and exclusion criteria, 9 cohort studies remained, consisting of 903 patients treated with either laser-assisted diverticulotomy (n = 283), transcervical diverticulectomy (n = 150), or stapler-assisted diverticulotomy (n = 470). A network meta-analysis was performed. Between endoscopic laser-assisted diverticulotomy and open diverticulectomy, the open approach showed a statistically lower likelihood of persistent/recurrent symptoms following treatment (odds ratio [OR], 0.20; 95% CI, 0.04-0.91). Comparing laser-assisted diverticulotomy with the stapler-assisted technique, there was not a significant difference between the 2 techniques (OR, 0.83; 95% CI, 0.43-1.60). The consistency model for the network meta-analysis was supported (χ21 = 0.12; P = .73).
CONCLUSIONS AND RELEVANCE
This systematic review and meta-analysis compared 3 common techniques for treating ZD. The open approach showed a decreased likelihood of persistent or recurrent symptoms following surgery compared with the 2 other techniques.
