Abstract Objectives The purpose of this study is to report a case of iatrogenic pharyngoesophageal diverticulum post‐anterior cervical discectomy and fusion (ACDF) surgery, its management and management of postoperative complications. We also did a thorough review of literature about iatrogenic pharyngoesophageal diverticulum which is a rarely encountered complication occurring after a commonly performed surgery; ACDF. Methods Here we describe a case of iatrogenic pharyngoesophageal diverticulum post‐ACDF surgery. In this paper we also make comparisons to the 23 cases reported in the literature in terms of: presentations, clinical findings, management courses, and complications. This study was approved by the Institution Review Board of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. (Ref. no.: IRB‐2023‐01‐473). The reported subject provided written informed consent before initiation of this study. Results Our case is a 45‐year‐old male with a history of ACDF surgery 8 years ago. He presented with dysphagia and regurgitations which started 1 year after ACDF. He was labeled as a case of Zenker's diverticulum and underwent multiple failed open and endoscopic surgeries prior to presenting to us. Upon presenting to our center, barium swallow showed the pharyngoesophageal diverticulum. Patient definitive diagnosis of iatrogenic rather than Zenker's diverticulum was established intra‐operatively with esophagoscopy which revealed exposed hardware inside the diverticulum. He underwent open diverticulectomy and diverticulopexy. Postoperatively he developed pharyngocutanous fistula and right vocal fold palsy, both successfully managed conservatively. Conclusion Iatrogenic Pharyngoesophageal diverticulum is a rare complication following ACDF, however prolonged dysphagia shall warrant further investigation by contrast studies. Open diverticulectomy with muscle reinforcement is a good management modality. Due to the complicated anatomy secondary to previous operations, we recommend conservative management for patients with postoperative pharyngocutaneous fistula.

Dysphagia after anterior cervical spine surgery (ACSS) may be secondary to pharyngoesophageal diverticulum. Our objectives are to (1) highlight the heterogeneity in clinical presentation, (2) discuss pathophysiology and management, and (3) present a comprehensive literature review of these diverticula. All patients undergoing pharyngoesophageal diverticulum repair between 2013 and 2019 were identified. Cases with ACSS history underwent detailed review of clinical presentation, assessment, and management. Literature review and analysis of all reported ACSS-associated pharyngoesophageal diverticula was performed. Two hundred forty-three cases of pharyngoesophageal diverticulum repair were performed during the study period; 13 cases were ACSS-associated. Four types of clinical presentation were identified: (Type A) Spinal hardware present, with videofluoroscopic evidence of exposed hardware; (Type B) Spinal hardware present, without videofluoroscopic evidence of exposed hardware; (Type C) Spinal hardware absent due to prior spinal hardware removal or ACSS performed without hardware; and (Type D) Concurrent esophago-esophageal fistula (EEF) present. All of our cases were evaluated using modified barium swallow study and esophagoscopy and definitively managed with endoscopic diverticulotomy. Literature review identified 21 cases of ACSS-associated pharyngoesophageal diverticulum repair from 18 publications. The majority of cases were identified using barium esophagram (N = 18, 86%) and managed with open diverticulectomy (N = 19, 90%). There were no reports of EEF. ACSS-associated pharyngoesophageal diverticulum must be evaluated with fluoroscopy and endoscopy, which determine presentation type. Presentation type guides management. Esophageal perforation requires hardware removal and perforation repair with flap placement. Endoscopic diverticulotomy was found essential to definitive management.Level of Evidence: 4.

Our review delves into the realm of peroral endoscopic myotomies (POEMs) in the upper gastrointestinal tract (UGT). In recent years, POEMs have brought about a revolution in the treatment of UGT motility disorders. Esophageal POEM, the first to be introduced, has now been validated as the primary treatment for achalasia. Subsequently developed, G-POEM displays promising results in addressing refractory gastroparesis. Over time, multiple endoscopic myotomy techniques have emerged for the treatment of Zenker's diverticulum, including Z-POEM, POES, and hybrid approaches. Despite the well-established efficacy outcomes, new challenges arise in the realm of POEMs in the UGT. For esophageal POEM, the future scenario lies in customizing the myotomy extent to the minimum necessary, while for G-POEM, it involves identifying patients who can optimally benefit from the treatment. For ZD, it is crucial to validate an algorithm that considers various myotomy options according to the diverticulum's size and in relation to individual patients. These challenges align with the concept of precision endoscopy, personalizing the technique for each subject. Within our text, we comprehensively examine each myotomy technique, analyzing indications, outcomes, and adverse events. Additionally, we explore the emerging challenges posed by myotomies within the context of the evolving field of precision endoscopy. [ABSTRACT FROM AUTHOR]

Objective: To assess barium esophagram (BAS) as a diagnostic marker for patients with Killian Jamieson diverticula (KJD). Methods: Prospective, multicenter cohort study of individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative. Patient demographics, comorbidities, radiographic imaging reports, laryngoscopy findings, patient‐reported outcome measures (PROM), and operative reporting were abstracted from a REDCap database and summarized using means, medians, percentages, frequencies. Paired t‐tests and Wilcoxon Signed Rank test were used to test pre‐ to post‐operative differences in RSI, EAT‐10, and VHI‐10 scores. Diagnostic test evaluation including sensitivity, specificity, positive, and negative predictive value with 95% confidence intervals were calculated comparing BAS findings to operative report. Results: A total of 287 persons were enrolled; 13 (4%) patients were identified with confirmed KJD on operative reports. 100% underwent open transcervical excision. BAS has a 46.2% (95% confidence interval [CI]: 23.2, 70.9) sensitivity and 97.8% (95% CI: 95.3, 99.0) specificity in detecting a KJD and 50% (95% CI: 25.4, 74.6) positive predictive value but 97.4% (95%CI: 94.8, 98.7) negative predictive value. Preoperatively, patients reported mean (SD) RSI and EAT‐10 of 19.4 (9) and 8.3 (7.5) accordingly. Postoperatively, patients reported mean (SD) RSI and EAT‐10 as 5.4 (6.2) and 2.3 (3.3). Both changes in RSI and EAT‐10 were statistically significant (p = 0.008, p = 0.03). Conclusion: KJD are rare and represent <5% of hypopharyngeal diverticula undergoing surgical intervention. Open transcervical surgery significantly improves symptoms of dysphagia. BAS has high specificity but low sensitivity in detecting KJD.

Submucosal endoscopy or third-space endoscopy utilizes the potential space between the mucosal and muscularis layers of the gastrointestinal tract to execute therapeutic interventions for various diseases. Over the last decade, endoscopic access to the submucosal space has revolutionized the field of therapeutic endoscopy. Submucosal endoscopy was originally used to perform endoscopic myotomy in patients with achalasia cardia, and its use has grown exponentially since. Currently, submucosal endoscopy is widely used to resect subepithelial tumors and to manage refractory gastroparesis and Zenker’s diverticulum. While the utility of submucosal endoscopy has stood the test of time in esophageal motility disorders and subepithelial tumors, its durability remains to be established in conditions such as Zenker’s diverticulum and refractory gastroparesis. Other emerging indications for submucosal endoscopy include esophageal epiphrenic diverticulum, Hirschsprung’s disease, and esophageal strictures not amenable to conventional endoscopic treatment. The potential of submucosal endoscopy to provide easy and safe access to the mediastinum and peritoneal spaces may open doors to novel indications and rejuvenate the interest of endoscopists in natural orifice transluminal endoscopic surgery in the future. This review focuses on the current spectrum, recent updates, and future direction of submucosal endoscopy in the gastrointestinal tract.

BACKGROUND: Killian-Jamieson diverticulum generally shows a protrusion of the lateral cervical wall of the proximal esophagus, it is originated in Killian-Jamieson space, considered a weak anatomical site, located below the cricopharyngeal muscle and lateral to the cervical esophagus longitudinal muscle. CLINICAL CASE: A male patient in his eighth decade of life, with large evolution dysphagia without approach or medical treatment. The causing of disease was the presence of an esophagus diverticulum of the Killian-Jamieson type. CONCLUSIONS: Killian-Jamieson diverticulum is much less frequent than the Zenker diverticulum; the difference between them is essential to the appropriate treatment. [ABSTRACT FROM AUTHOR]

Objective: We aim to explore the differences in complication rates in endoscopic versus open transcervical treatment of Zenker diverticulum., Study Design: Retrospective Cohort Study from January 1, 2015 to December 31, 2023., Setting: Queries of the TriNetX database's United States Collaborative Network., Methods: A retrospective cohort study was conducted using patients ≥18 years old diagnosed with Zenker diverticulum selected from the TriNetX United States Collaborative Network. Patients undergoing open and endoscopic diverticulectomy between 2015 and 2023 were identified and divided into cohorts and propensity score matched by age, sex, race, ethnicity, and common comorbidities., Results: Patients that underwent transcervical approach (n = 1033), when compared to patients that underwent endoscopic approach (n = 2182), had higher rates of dysphonia (odds ratio [OR]: 2.44; 95% confidence interval [CI]: 1.47-4.05; P = .001), long-term enteral feeding access (OR: 3.08; 1.74-5.46; P > .001), and infection (OR: 6.65; 3.50-12.65; P > .001). No significant difference was found in rates of esophageal perforation (OR: 1.60; 0.93-2.75; P = .087) or persistent postoperative dysphagia (OR: 1.03; 0.86-1.23, P = .75). There was no significant difference in the number of patients receiving repeat diverticulectomy procedures (OR: 0.83; 0.58-1.19; P = .314)., Conclusion: Based on analysis of a large healthcare database, endoscopic Zenker diverticulectomy is associated with rates of postoperative dysphonia, enteral feeding, and soft tissue infection. Both the open and endoscopic approaches offer relative advantages not captured by this population-level analysis. Thus, judicious selection of patients based on comorbidities and anatomical factors is essential for optimizing outcomes., (© 2025 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Abstract Saccharomyces cerevisiae is a yeast microorganism known to inhabit the gut micro-biome. It is commonly used in the fermentation process of beer, wine, bread making, and is naturally found in soil, plants, and fruit. Saccharomyces boulardii (subtype of Saccharomyces) and cerevisiae are closely related and are commonly used as a probiotic and in treatment for diarrhea. In rare circumstances, Saccharomyces has been shown to cause infection in the immunocompromised and intensive care unit (ICU) patients, with antibiotic use, and central venous catheter use. This prompts us to present one of the only documented case reports of a lung parenchyma infection with Saccharomyces cerevisiae in a 64-year-old immunocompetent male with a past medical history of chronic obstructive pulmonary disorder (COPD), atrial fibrillation, atrioventricular (AV) nodal ablation, heart failure with preserved ejection fraction (HFrEF (post-status automated implantable cardioverter-defibrillator)), coronary artery bypass graft (CABG), gastric esophageal reflux disease (GERD), and a Zenker diverticulum.

Introduction Zenker diverticulum (ZD) usually affects adults after the 7th decade of life. Treatment for ZD is indicated for all symptomatic patients, but some patients prefer to defer surgical treatment until symptoms get worse and decrease their quality of life. Objective To evaluate the association of the preoperative symptoms in ZD patients with the size of the ZD. Methods A retrospective study design. Electronic medical records were used to identify patients diagnosed with ZD and treated over 11 years. Data collection included the chief complaints and symptoms, medical history, and findings on radiologic swallow evaluations of the patients. The diverticulum size was stratified into 3 groups: small (< 1 cm), moderate (1-3 cm), and large (> 3 cm). Results A total of 165 patients were enrolled and stratified by diverticulum size (48 small, 67 medium, and 50 large). Dysphagia, cough, and regurgitation were the most prevalent symptoms. Dysphonia was more frequent among patients with a small pouch. Logistic regression analysis showed that dysphagia and choking were associated with large and medium diverticulum size (p<0.05). Additionally, dysphonia was significantly associated with the presence of a small-sized ZD (p<0.04). Conclusion Upper gastrointestinal symptoms such as dysphagia and choking may be associated with a ZD>1 cmand should always be evaluated. Additionally, the presence of dysphonia was found to be correlated with a ZD<1 cm, suggesting that a prompt and appropriate fluoroscopic evaluation must be considered in those patients in whom no other clear cause of dysphonia is evident.

Cricopharyngeal spasm and pharyngeal pouch can result in severe dysphagia symptoms that can have a significant impact on a patient's quality of life. Several surgical interventions have been demonstrated including balloon dilatation, botox injection, and open and endoscopic cricopharyngeal myotomy. The aim of this case series is to describe our technique for endoscopic cricopharyngeal myotomy and compare pre- and postoperative swallowing outcomes using objective swallowing questionnaires in a small series of patients. Seven patients diagnosed with cricopharyngeal spasm or grade 1 pharyngeal pouch on barium swallow were prospectively observed. MD Anderson Dysphagia inventory (MDADI) and Dysphagia handicap index (DHI) were given to patients before and after their operation. All patients underwent the same surgical technique with the cricopharyngeal bar divided and the defect closed with dissolvable sutures. Mean inpatient stay was 7 days (range 1-8) and mean time to resumption of soft diet was 4 (range 1-7) days. All patients resumed oral diet before discharge. MDADI scores showed improvement across all domains, however only the emotional score achieved statistical significance (P =.04). Dysphagia handicap index scores showed a statistically significant improvement across functional, emotional, and total domains. Postoperative chest infection treated with oral antibiotics occurred in 3 patients (43%) and no other complications were documented. In conclusion, endoscopic cricopharyngeal myotomy with primary sutured endoscopic closure can result in a significant benefit to patient's swallowing symptoms, emotional well-being, and quality of life.

Background: Zenker's peroral endoscopic myotomy (Z-POEM) has revolutionized the therapeutic strategy for Zenker's diverticulum (ZD) with promising results. We conducted this meta-analysis to estimate the safety and efficacy of Z-POEM for ZD and compare the feasibility and effectiveness of Z-POEM with that of flexible endoscopic septotomy (FES).Methods: A comprehensive literature search was conducted in PubMed, EMBASE, Web of Science, and Cochrane Library databases to query for studies that assessed the safety and efficacy of Z-POEM for ZD. All articles published from inception to July 31, 2021 were included. The primary outcomes were the overall technical success rate, clinical success rate, incidence of adverse events, and clinical recurrence rate.Results: Eleven studies involving 357 patients undergone Z-POEM were included. Overall, the quality of included studies was above average, with five studies rated as high quality and six ranked as moderate quality. The overall pooled technical success rate for Z-POEM was 96.3% (95% confidence interval [CI] 93.6-97.9%; I2 = 0%). The total pooled clinical success rate for Z-POEM was 93.0% (95% CI 89.4-95.4%; I2 = 0%). The pooled incidence of adverse events for Z-POEM was 12.4% (95% CI 9.1-16.7%; I2 = 0%). The pooled clinical recurrence rate for Z-POEM was 11.2% (95% CI 7.6-16.2%; I2 = 0%). The clinical success for Z-POEM was significantly better than that of FES (relative risk [RR]: 1.11; CI 95% 1.03-1.18; p = 0.004, I2 = 0%), while there were no significant differences in technical success, adverse events, and clinical recurrence between Z-POEM and FES.Conclusion: Z-POEM could be an effective and safe therapeutic modality for ZD, and even has a slightly higher clinical success rate than FES. However, comparative studies with long-term follow-up will be needed to further confirm our finding. [ABSTRACT FROM AUTHOR]

Zenker’s diverticulum (ZD) is a rare condition that predominantly effects elderly population. Dysphagia and regurgitation are the common presenting symptoms in patients with ZD. Flexible endoscopic diverticulotomy (FED) of the cricopharyngeal septum is the mainstay of management in symptomatic ZD. The outcomes of FED compare favorably to open surgical and trans-oral rigid endoscopic treatment methods. Moreover, FED is associated with relatively fewer morbidities as compared to surgery. Bleeding and micro-perforation are the most commonly reported immediate adverse events. Majority of the adverse events are mild and severe adverse events are rare with FED. Recurrence of symptoms remain the most important long-term concern after FED. Nevertheless, majority of the recurrences respond to a repeat session of endoscopic treatment. Lately, new electrosurgical knives and novel endoscopic techniques of cricopharyngeal myotomy have been evaluated for the treatment of ZD. Novel techniques include double incision with snare resection and submucosal tunneling endoscopic septum division. The proposed advantage with these techniques is possible reduced incidence of recurrences after endoscopic treatment. Randomized comparison studies are required between new and conventional flexible endoscopic techniques. In addition, standardized reporting of clinical success, and adverse events is required in future studies.

Aim: The aim of our study was to examine the results of surgical treatment of patients with cervical diverticula of the oesophagus over a period of 20 years. Materials and methods: The study was a retrospective analysis of 65 patients with cervical diverticula of the oesophagus treated between 2000 and 2020. Patients with symptoms such as dysphagia, vomiting, chocking, recurrent respiratory tract inflammation, as well as patients with diverticular recurrence or poor outcome of primary surgery, were qualified for surgical resection of the oesophageal diverticulum with myotomy using an open technique. Patients were evaluated for degree of dysphagia before and after surgery, associated perioperative complications, and overall comfort after surgical treatment. Results: Sixty-five patients underwent surgical treatment, 7 (10.7%) of whom were treated for diverticular recurrence or poor outcome of primary treatment. The predominant symptom was dysphagia, which was found in 55 (84.6%) patients, increasing over a period of 6 to 48 months with a mean of 17.6 months. The size of the diverticulum ranged from 2 to 6 cm with a mean of 4.8 cm. One patient (1.5%) who experienced suture line leak was treated conservatively, and the fistula healed. Another patient had permanent vocal cord damage while 1 (1.5%) patient had transient damage. The surgical outcome was very good in 38 (69.1%) patients, good in 15 (27.2%) patients, and poor in 2 (3.6%) patients. No postoperative death occurred. Conclusion: Transcervical method of treating diverticula is a safe way of dealing with an acceptable complication rate. It can be an alternative to endoscopic methods. It should be the method of choice in patients treated for recurrent diverticula after endoscopic treatment. [ABSTRACT FROM AUTHOR]

Background: Various endoscopic methods of dividing the cricopharyngeus muscle and the common wall of pharyngeal pouches have been described, most commonly the carbon dioxide laser and stapler. The potassium titanyl phosphate (KTP) laser is an alternate endoscopic method of treatment. Methods: The KTP laser is used in a similar fashion to the carbon dioxide laser to carefully divide the cricopharyngeus muscle fibres ± the common wall of the pharyngeal pouch, under microscopic visualization. Conclusion: The KTP laser is an alternative and safe technique for these surgeries. [ABSTRACT FROM AUTHOR]

Introduction: Different treatments exist for Zenker diverticulum. We compared flexible endoscopic myotomy of the cricopharyngeal muscle, using a technique called the "window technique" in order to improve the field of view, to surgical approaches.Materials and Methods: Patients were retrospectively included and divided into a gastrointestinal group, with flexible endoscopic myotomy, and an ear-nose-throat treatments group with either rigid endoscopic treatment, either cervicotomy. We evaluated effectiveness in terms of quality of life (on a scale on 0 to 10) safety and technical aspects of each procedure.Results: A total 106 patients who underwent 128 interventions were included. Rigid endoscopic procedures were the shortest (p < 0.001), with no difference for adverse event. Endoscopic approaches, flexible and rigid ones, were associated with shorter time to intake resumption (1 and 3 days, respectively, vs 6 after cervicotomy) and shorter length of hospital stay (3 and 4 days, respectively, vs 7 after cervicotomy) (p = 0.001). Post-operative QoL was better after flexible endoscopy (9/10) and open cervicotomy (9/10) than after rigid endoscopy (7/10) (p = 0.004). Patients declared fewer residual symptoms after open cervicotomy (77% of low symptomatic patients) and flexible endoscopy (80%) than after rigid endoscopy (43%) (p = 0.003). Conversion to open surgery was more frequent during rigid than flexible endoscopies (18% vs 0%, p = 0.0008).Conclusion: Flexible endoscopic approach of Zenker diverticulum treatment seems to be safe and effective and may be an alternative to surgical approaches. Myotomy can be eventually helped by the window technique. [ABSTRACT FROM AUTHOR]

Purpose: Despite the evolution of the endoscopic techniques for the treatment of symptomatic Zenker diverticulum, comparative studies are lacking. Aim of this observational study was to compare safety, efficacy, and outcomes of endoscopic stapling (ES) versus Laser (EL). Methods: A prospectively collected database of patients who underwent treatment for Zenker diverticulum at a single institution was reviewed. Consecutive patients treated by ES or EL were included in the study. Demographic data, presenting symptoms, diverticulum characteristics, and intra- and postoperative data were analyzed. The Functional Outcome Swallowing Scale (FOSS) and MD Anderson Dysphagia Inventory (MDADI) questionnaires were administered to assess severity of dysphagia and quality of life before and after treatment. Results: Between March 2017 and September 2018, 36 patients underwent ES or EL. In the TL group (n = 19), the diverticulum size was smaller compared to the EL group (n = 17) (p = 0.002). Two perforations occurred in the EL group, one treated conservatively and the other requiring drainage of a mediastinal abscess. At a median follow-up of 16 months, symptoms improved in both groups but the number of patients with a postoperative FOSS score ≥ 2 significantly decreased only after EL (p < 0.001). The scores of all items of the MDADI questionnaire significantly increased in both groups, but the average delta values were greater in the EL patients (p < 0.001). Conclusions: Both TL and ES are effective treatment options for Zenker diverticulum. Postoperative quality of life was significantly higher in patients undergoing EL compared to ES.

Although barium swallow imaging is established in the investigation of Zenker's diverticulum (ZD), no agreed measurement protocol exists. We developed a protocol for measuring ZD dimensions and aimed to correlate measurements with symptoms and post-operative outcomes. This prospective study included patients with confirmed ZD who underwent flexible endoscopic septal division (FESD) between 2014 and 2018. ZD was confirmed on barium radiology with measurements reviewed by two consultant radiologists. Symptom severity pre- and post-FESD was measured using the Dysphagia, Regurgitation, Complications (DRC) scale. Regression analyses were conducted to identify dimensions associated with therapeutic success, defined as remission (DRC score ≤ 1) 6 months after index FESD. In total, 67 patients (mean age 74.3) were included. Interobserver reliability (intraclass correlation coefficients-ICCs) was greatest for pouch width (0.981) and pouch depth (0.934), but not oesophageal depth (0.018). Male gender (60.9%) was associated with larger pouch height (P = 0.008) and width (P = 0.004). A positive correlation was identified between baseline DRC score and pouch depth (ρ 0.326, P = 0.011), particularly the regurgitation subset score (ρ 0.330, P = 0.020). The index pouch depth was associated with FESD procedure time (rho 0.358, P = 0.041). Therapeutic success was achieved in 64.2% and was associated with shorter pouch height (median 14.5 mm vs. 19.0 mm, P = 0.030), pouch width (median 19.9 mm vs. 28.8 mm, P = 0.34) and cricopharyngeal length (median 20.2 mm vs. 26.3 mm, P = 0.036). ZD dimensions may be feasible and were evaluated using Barium radiology. Specific parameters appear to correlate with severity and post-FESD outcomes, which aid with pre-procedural planning.

Background: There are sparse data on the outcomes of endoscopic stapling of pharyngeal pouches. The Mersey ENT Trainee Collaborative compared regional practice against published benchmarks. Methods: A 10-year retrospective analysis of endoscopic pharyngeal pouch surgery was conducted and practice was assessed against eight standards. Comparisons were made between results from the tertiary centre and other sites. Results: A total of 225 procedures were performed (range of 1.2–9.2 cases per centre per year). All centres achieved 90 per cent resumption of oral intake within 2 days. All centres achieved less than 2-day hospital stays. Primary success (84 per cent (i.e. abandonment of endoscopic stapling in 16 per cent)), symptom resolution (83 per cent) and recurrence rates (13 per cent) failed to meet the standard across the non-tertiary centres. Conclusion: Endoscopic pharyngeal pouch stapling is a procedure with a low mortality and brief in-patient stay. There was significant variance in outcomes across the region. This raises the question of whether this service should become centralised and the preserve of either tertiary centres or sub-specialist practitioners. [ABSTRACT FROM AUTHOR]

Objective: Transoral diverticulostomy/septotomy has become a popular treatment for patients with Zenker diverticulum (ZD). To improve the results of transoral stapler-assisted septotomy, a modification of the technique has been introduced. In this study, we aimed to compare the final outcome of such a modified transoral septotomy (MTS) with the results of traditional transoral septotomy (TTS) in patients with ZD.Methods: Fifty-two consecutive patients with ZD underwent transoral stapler-assisted septotomy between 2010 and 2018. Symptoms were recorded and scored using a detailed questionnaire. Barium swallow, endoscopy, and manometry were performed before and after the procedure.Results: Of the 52 patients forming the study population (male:female = 35:17), 25 had TTS and 27 had MTS. The patients' demographic and clinical parameters were similar in the two groups. No intraoperative mucosal lesions were detected, and the mortality was nil. The median time taken to complete the procedure was 25 minutes (interquartile range [IQR]: 22-35) for TTS, and 30 minutes (IQR: 25-36) for MTS (P < 0.07). The median follow-up was 69 months (IQR: 46-95) in the TTS group and 30 months (IQR: 25-35) in the MTS group. All patients in both groups had an improvement in their symptom score after the procedure, but the failure rates were 32% (8 of 25) after TTS and 3.7% (1 of 27) after MTS (P < 0.02). At univariate and multivariate analyses, the procedure was the only predictor of a positive final outcome.Conclusion: Albeit with the intrinsic limitations of the study (retrospective, different time window, and different follow-up), traction on the septum during transoral septotomy improves the final outcome of this treatment in patients with ZD.Level Of Evidence: 4 Laryngoscope, 130:637-640, 2020.

A 73-year-old male patient presented to the Emergency Department with history of weight loss, dysphagia, and recurrent fever. The initial chest radiograph showed a mediastinal hypotransparency and to the complaints of dysphagia the patient did a barium swallow test that revealed a giant Zenker diverticulum. Apart from mildly elevated inflammatory markers and despite the extensive investigation of recurrent fever, no other relevant features were found either in blood analysis, microbiological cultures or computerized tomography. He was submitted to surgical intervention, with no recurrence of fever afterwards. It was assumed that food debris and possible microaspirations were responsible for the recurrence of fever and elevation of inflammatory markers. The patient eventually died due to late complications of surgery. Although recurrent fever is frequently linked to systemic disease, the presence of such a giant diverticulum was probably causing an inflammatory response that is usually not seen in these conditions.

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.

The study is devoted to the peculiarities of surgical treatment of Zenker diverticulum. For convenience and for safety we propose the use of intraoperative video endoscopic transillumination of the diverticulum. The method significantly increases the safety of operation, shortens its duration and results to a better cosmetic effect. To avoid relapse, diverticulectomy should be supplemented by cricopharyngeal myotomy.
