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.

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.

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.

Meta-Analysis
BACKGROUND AND AIM
Either clipping or band ligation will become the most common endoscopic treatment for colonic diverticular bleeding (CDB). Rebleeding is a significant clinical outcome of CDB, but there is no cumulative evidence comparing reduction of short-term and long-term rebleeding between them. Thus, we conducted a systematic review and meta-analysis to determine which endoscopic treatment is more effective to reduce recurrence of CDB.
METHODS
A comprehensive search of the databases PubMed/MEDLINE and Embase was performed through December 2019. Main outcomes were early and late rebleeding rates, defined as bleeding within 30 days and 1 year of endoscopic therapy for CDB. Initial hemostasis, need for transcatheter arterial embolization, or surgery were also assessed. Overall pooled estimates were calculated.
RESULTS
Sixteen studies fulfilled the eligibility criteria, and a total of 790 participants were included. The pooled prevalence of early rebleeding was significantly lower for band ligation than clipping (0.08 vs 0.19; heterogeneity test, P = 0.012). The pooled prevalence of late rebleeding was significantly lower for band ligation than clipping (0.09 vs 0.29; heterogeneity test, P = 0.024). No significant difference of initial hemostasis rate was noted between the two groups. Pooled prevalence of need for transcatheter arterial embolization or surgery was significantly lower for band ligation than clipping (0.01 vs 0.02; heterogeneity test, P = 0.031). There were two cases with colonic diverticulitis due to band ligation but none in clipping.
CONCLUSION
Band ligation therapy was more effective compared with clipping to reduce recurrence of colonic diverticular hemorrhage over short-term and long-term durations.

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
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.

Meta-Analysis
Peroral endoscopic myotomy (POEM) is a rapidly evolving technique for the treatment of esophageal diverticulum. The aim of this study was to perform a systematic review and meta-analysis of the literature focusing on POEM for symptomatic esophageal diverticula, including an in-depth evaluation of its efficacy, safety, and limitations. A comprehensive literature search was completed to identify articles that examined the efficacy and safety of POEM for esophageal diverticula. Heterogeneity among studies was assessed using the I2 statistic. Meta-regression and sensitivity analyses were performed to explore the sources of heterogeneity and assess potentially important covariates influencing the main outcomes. Primary endpoints such as rates of success, adverse events, and recurrences were evaluated. P values of ≤0.05 were considered statistically significant. Nine studies with a total of 153 patients were enrolled. Pooled technical success, clinical success, adverse events, and recurrence rates were 99% [95% confidence interval (CI), 97-100%; I2 = 0%), 94% (95% CI, 89-97%; I2 = 24%), 2% (95% CI, 0-6%, I2 = 0%), and 0% (95% CI, 0-1%; I2 = 0%), respectively. The pooled perforation rate was 6% (95% CI, 1-11%; I2 = 0%). Meta-regression analysis indicated that esophageal diverticula types and motility disorders were not associated with the clinical success rate (P > 0.05). POEM is a feasible, safe, and effective treatment for symptomatic esophageal diverticula, with low adverse events and recurrence rates.

Meta-Analysis
BACKGROUND
The aim of this study was to determine the prevalence and anatomic features of major tracheobronchial anomalies.
METHODS
Major electronic databases were systematically searched to identify eligible studies. Data were extracted and pooled into a meta-analysis. The primary outcome was the prevalence of major tracheobronchial anomalies, specifically tracheal bronchus (TB) and accessory cardiac bronchus (ACB). Secondary outcomes included the origin and types of TB and ACB.
RESULTS
A total of 27 studies (n = 119,695 patients) were included. A TB was present in 0.99% (95% confidence interval, 0.67 to 1.37) of patients, and an ACB was present in 0.14% (95% confidence interval, 0.09 to 0.20). The overall prevalence of TB was higher in imaging than in operative studies (1.81% vs 0.82%). It was also higher in pediatric (2.55%) than in adult studies (0.50%). Patients with other congenital anomalies were 15 times more likely to have a TB (odds ratio 14.89; 95% confidence interval, 7.09 to 31.22). The most common origin of TBs was from the trachea (81.42%), primarily from the right side (96.43%). The most common origin of ACBs was from the intermediate bronchus (74.32%). The ACBs terminated as blind-ending diverticulum in two thirds of cases.
CONCLUSIONS
Major tracheobronchial anomalies are present in approximately 1% of the population, although the prevalence is higher among pediatric patients and patients with accompanying congenital anomalies. Although rare, major tracheobronchial anomalies can be associated with significant respiratory morbidities and present challenges during airway management in surgical and critical care patients. Establishing a preoperative diagnosis of these variations is essential for planning and implementing an appropriate airway management strategy to minimize attendant complications.

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.

Pediatric Surgery International Nov 2020This study reviewed the literature on the postoperative complications following laparoscopic-assisted anorectoplasty (LAARP).
AIM
This study reviewed the literature on the postoperative complications following laparoscopic-assisted anorectoplasty (LAARP).
METHODS
A Medline and Embase search was performed for the terms "anorectal malformation" (ARM) "laparoscopic" and "complication". Articles without English full text, review articles, systematic reviews, case reports, case series < 5 cases and duplicate articles were excluded. Two reviewers independently performed the eligibility assessment and data extraction. Data were collected for type of malformation, surgical technique, postoperative complications and functional outcomes RESULTS: The search retrieved 108 articles, of which 38 met the inclusion criteria and offered 1058 patients for analysis. Rectoprostatic and rectobladder neck fistula were the most common types of ARM in males, whereas it was the common cloaca in females. Analysis of complications demonstrated rectal prolapse (n = 149; 14.08%) being the most prominent, followed by urethral diverticulum (n = 32; 3.02%), anal stenosis (n = 37; 3.49%), recurrent fistula (n = 7; 0.66%) and rectal stricture (n = 4; 0.37%). Krickenbeck classification was used for functional assessment in 638 patients, with fecal soiling grade 2 or > 2 in 79. Data on functional outcome specific to the type of malformation was available for 246 patients: fecal soiling grade 2 or > 2 in 15/94 (15.95%) with rectoprostatic fistula, 26/73 (35.61%) with rectobladder neck fistula, 6/47 (12.76%) with common cloaca, and 1/22 (4.54%) with no fistula.
CONCLUSION
Rectal prolapse, posterior urethral diverticulum and anal stenosis are the most common complications after LAARP. Inconsistent and non-uniform functional assessment and non-availability of information about the sacrum and spine make it difficult to analyze the functional outcome following LAARP.
