Ligamentum Teres Augmentation for Hiatus Hernia Repair After Bariatric Surgery: A Systematic Review and Meta-analysis.

OBJECTIVE: Hiatal hernia (HH) and symptomatic gastroesophageal reflux disease are common complications after metabolic bariatric surgery. This meta-analysis aims to investigate the safety and efficacy of ligamentum teres augmentation (LTA) for HH repair after metabolic and bariatric surgeries (MBS). MATERIALS AND METHODS: CENTRAL, Embase, PubMed, and Scopus were searched for articles from their inception to September 2023 by 2 independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis system. RESULTS: Five studies met the eligibility criteria, with a total of 165 patients undergoing LTA for HH repair after MBS. The distribution of patients based on surgical procedures included 63% undergoing sleeve gastrectomy, 21% Roux-en-Y gastric bypass, and 16% having one anastomosis gastric bypass. The pooled proportion of reflux symptoms before LTA was 77% (95% CI: 0.580-0.960; I2 = 89%, n = 106). A pooled proportion of overall postoperative symptoms was 25.6% (95% CI: 0.190-0.321; I2 = 0%, n = 44), consisting of reflux at 14.5% (95% CI: 0.078-0.212; I2 = 0%, n = 15). The pooled proportion of unsuccessful LTA outcomes was 12.5% (95% CI: 0.075-0.175; I2 = 0%, n = 21). CONCLUSION: Our meta-analysis demonstrated that LTA appears to be a safe and efficacious procedure in the management of HH after MBS.

Functional Status Predicts Delay to Radiation in Free Tissue Transfer for Head and Neck Cancer.

OBJECTIVE: Evaluate the effect of functional status and patient factors on delays in treatment with adjuvant therapy. METHODS: Retrospective chart review (2020-2022) was conducted at a single tertiary referral center. Data were collected between January 2020 and October 2022, and 63 patients underwent free flap reconstructive surgery of the head and neck due to the presence of cancer and received adjuvant radiation therapy (RT). The main outcomes measured were Area Deprivation Index (ADI), Beale scores, distance to radiation center, functional status, patient demographics, gender, and length from surgery to initiation of RT. RESULTS: Of the 63 patients who were reviewed, the average age was 65.5 years old and 63.8% were male. The average ADI state score was 5.6 and the national percentile of 77.1. The average Beale score was 3.7. The average distance traveled was 101.1 miles. Thirty-five patients were living independently, 16 were living in assisted living or received home care, and 15 were dependent or lived in a nursing home. Mann-Whitney U analysis revealed a significant association of increasing levels of dependence to delays in treatment compared to on-time treatment (p = 0.002). The odds of treatment delay were increased almost 10-fold for every additional increase in dependency level (OR = 9.87, 95% CI = 1.42-68.83). CONCLUSIONS AND RELEVANCE: Degree of dependent functional status correlates with delays in postoperative adjuvant RT in patients undergoing free tissue transfer for head and neck cancer. Preoperative risk stratification allows for physicians to address barriers to adjuvant therapy prior to delay. LEVEL OF EVIDENCE: Level 3 Laryngoscope, 2024.

Functional Outcomes After the Sacrifice of Mandibular Condyle Using Fibula Free Flap for Immediate Surgical Reconstruction.

Introduction Head and neck cancer with mandibular invasion often necessitates composite resection, leading to defects requiring reconstruction. Microvascular fibula free flap (FFF) surgery is a common approach for this purpose. In this study, we focus on our experience with condyle sacrifice, emphasizing treatment outcomes and functional results. Additionally, we highlight a contemporary perspective by discussing surgical techniques and radiographic outcomes based on a 3D analysis of neo-condyle placement on CT imaging. Methods We studied 23 patients who had undergone segmental mandibulectomy requiring FFF reconstruction between 2009 and 2020. These were all performed by the same surgeon (M.M.) at an academic tertiary care center. Twenty-three reconstructions included condyle sacrifice. Retrospective chart review was performed with a focus on treatment, functional outcomes, and surgical technique. Results A total of 23 patients were included in the study group (13 females and 10 males) with a mean age of 58.1 years. The most common surgical indication was for oncologic purposes (n=9; 39.1%). Twenty (87%) patients required tracheostomy, and all were decannulated. In terms of surgical complications, two (8.7%) patients had a degree of arterial insufficiency and two (8.7%) developed delayed infections. The average inpatient stay was 5.61 days, with a subsequent average clinic follow-up after 16.9 days. CT or MRI imaging was available for 21 (91.3%) patients, showing 14 (66.7%) neo-condyles within the glenoid fossa. Fifteen (71.4%) patients had some element of anterior displacement (average=6.27 mm), and seven (33.3%) patients had a component of lateral displacement (average=2.23 mm). Three (13%) patients died during the follow-up period. Eighteen (90%) of the surviving patients returned to an oral diet within an average of 24.9 days. All patients returned to normal interincisal distance by 12 months. All FFFs, with and without complications, remained viable. Conclusion We achieved favorable oral function outcomes in the majority of our patients. Intriguingly, although radiographic evidence revealed anterior and/or lateral displacement of the neo-condyle, there was no observed correlation with the resumption of oral diet, trismus, or crossbite among these patients.

Elective Neck Dissection in Patients Undergoing Salvage Laryngectomy: Outcomes, Complications, and Considerations.

Objective In this study, we sought to identify the predictors for occult nodal disease (OND) and compare oncologic outcomes in patients undergoing elective neck dissection (END) at the time of salvage laryngectomy (SLE) versus the observation group. Methods A retrospective chart review was conducted involving all patients with clinically node-negative (cN0) necks who underwent SLE at a tertiary academic center over 12 years. A total of 58 patients met the inclusion criteria and were divided into two groups: END (n=39) and observation (n=19). Primary endpoints were OND, regional recurrence-free survival (RRFS), and disease-specific survival (DSS). Univariate analysis was performed to establish the association between variables with Fisher's exact test and Mann-Whitney U test. Survival analysis was performed with the log-rank test. Results The cohort comprised 46 (79.3%) males and 12 (20.7%) females, with a mean age of 60 years. Pathological nodal disease was identified in five of 71 (7%) examined neck dissection specimens, with positive nodes found in levels II through IV. The only statistically significant predictor of OND was the rT3/rT4 stage (p=0.017). There were no differences in perioperative complications, RRFS (p=0.216), or DSS (p=0.298) between the END and observation groups. Conclusions In cN0 necks, the advanced recurrent T-stage (rT3-rT4) is a predictor for OND. As OND was found involving levels II, III, and IV in this study's specimens, formal lateral neck dissection should be the procedure of choice if END is to be performed alongside SLE. While END did not show a significantly higher morbidity profile versus conservative management in this cohort, the procedure did not improve loco-regional control or survival, even when stratifying by tumor stage.

The Role of Telemedicine in Voice Therapy.

Introduction: During the COVID-19 pandemic, our institution adopted telemedicine for voice therapy (VT) as an alternative to in-person sessions, which has been integrated into our routine practice following the pandemic. This study aims to explore factors influencing completion rates among the 2 methods. Method: A retrospective chart review at a single tertiary care institution between 2019 and 2021 was conducted. Patient zip codes were used to determine Neighborhood Atlas® Area Deprivation Index (ADI) scores and travel distance to our institution. Demographic data, Voice Handicap Index (VHI) scores, and completion status were extracted. Results: Between 2019 and 2021, 521 patients were referred to VT at our institution, with 29% opting for telemedicine VT (TVT) sessions and 71% choosing in-person sessions. Seventy-four percent was female, and average age was 57.1 years (range:10-89 years old). No statistically significant differences were observed between the 2 groups regarding sex, age, employment status, or insurance type. Participants in the TVT group demonstrated notably higher completion rates compared to the in-person group [70.0% vs 31.6% (P < .001)]. The TVT group also comprised of a higher percentage of white patients, reported longer travel distances and times to reach therapy, but had comparable ADI scores to the in-person group. Moreover, there were no significant differences in pretreatment VHI scores between the 2 groups or between those who completed therapy versus those who did not (P = .501). Conclusion: Our findings indicate that patients utilizing the telemedicine platform had significantly higher VT completion rates compared to patients appearing in person. These results highlight the importance of being able to offer telemedicine-based options in the management of voice patients.

Utility of video fluoroscopic swallow study in advancing oral diet post TORS for oropharyngeal malignancies.

OBJECTIVE: TORS is a minimally invasive surgical alternative to chemoradiotherapy for oropharyngeal malignancies. While early postoperative oropharyngeal dysphagia is linked to TORS, this study explores both subjective and objective swallowing outcomes. STUDY DESIGN: Retrospective and prospective review of the patients who underwent TORS for oropharyngeal malignancy from 2018 to 2023. SETTING: Single tertiary referral center. METHODS: Postoperative transnasal feeding tubes were administered to 142 patients undergoing TORS. Data on oncological, clinical, surgical, and pathological parameters, including VFSS records, pain with swallow, and feeding tube removal timing, were collected. Clinical swallow exam (CSE) was conducted on POD-1, with a formal swallow study pursued if inconclusive. Once a safe swallow was confirmed, oral diets were initiated, and the feeding tube removed, with most patients discharged on POD-2. RESULTS: At an average age of 59.3 years on the day of operation, the palatine tonsil (N = 101) was the predominant subsite. A dobhoff feeding tube was intraoperatively placed in 98 % of patients (N = 139). On POD-1, CSE was conducted in 119 patients, with 26 % (37/119) cleared for total oral diet (NOMS ≥ 4). Additionally, 30 out of 73 VFSS patients were cleared for total oral diet. A total of 54.9 % (78/142) had the feeding tube removed before discharge on POD-2, with a mean time of 6.5 ± 6.6 days. Overall, 71.1 % (101/142) achieved a total oral diet within one week after TORS. CONCLUSION: Early post-TORS swallowing is vital for oropharyngeal malignancies. VFSS assesses post-operative swallowing safety, allowing most patients to resume total oral nutrition shortly after TORS.

Oncologic Outcomes of Salvage Surgery in Recurrent Oral Tongue Squamous Cell Carcinoma.

OBJECTIVE: This study aimed to determine the oncologic outcomes and identify prognostic factors in patients undergoing salvage glossectomy for recurrent oral tongue squamous cell carcinoma (OTSCC). METHODS: A retrospective chart review was conducted encompassing all patients who underwent salvage oral glossectomy out of 259 individuals undergoing oral glossectomy at a tertiary academic center. Inclusion criteria comprised patients who met the following conditions: 1) biopsy-proven oral tongue recurrence, 2) salvage glossectomy performed with curative intent, 3) availability of imaging records, and 4) comprehensive documentation. Cases involving base of tongue tumors and second primaries were excluded from the analysis. Categorical data were expressed as proportions, and continuous data as medians/quartiles. Univariate analysis used Fisher's exact test for categorical variables and Student's t-test for continuous ones. Survival analysis employed Kaplan-Meier estimates and the log-rank test. RESULTS: High-risk histopathological risk factors were significantly more common with recurrence compared to initial presentation. The mean locoregional disease-free interval was 35 months. Kaplan-Meier estimates for one- and three-year disease-free survival (DFS) were 62.7% and 33.4%, while disease-specific survival (DSS) rates were 73% and 38.9%, respectively. Recurrent T-stage was a predictor for DFS, while margin status was a strong predictor for both LR control (p = 0.024) and DSS (p = 0.030), as was perineural invasion (p = 0.001 and p = 0.030). Alcohol use was associated with worse overall survival (p = 0.024). In contrast to other reports, nodal status was not a predictor in this series. CONCLUSIONS: Upon recurrence, histopathological analysis unveils detrimental changes in tumor biology, which significantly influence disease control. Notably, consistent with findings from other studies, factors, such as recurrent T-stage, presence of perineural invasion, and, most importantly, margin status, play pivotal roles in determining oncologic outcomes. Consequently, the imperative for aggressive salvage surgery becomes evident in achieving sufficient disease control. This underscores the necessity for proactive management strategies aimed at addressing these factors to enhance patient outcomes.

Auditory brainstem implants: an analysis of adverse events in the MAUDE database.

OBJECTIVE: Auditory Brainstem Implants (ABI) are used to restore hearing in patients lacking appropriate cochlear anatomy and/or cochlear nerve. The objective of this study was to examine the Manufacture and User Facility Device Experience (MAUDE) database to analyze adverse events. STUDY DESIGN: This is a study of a multi-institutional database maintained by the US FDA. SETTING: A database analysis was performed via collaboration of multiple clinicians at tertiary referral centers. METHODS: The MAUDE database was queried for Medical Device Reports (MDRs) relating to ABIs. MDRs were identified using the advanced search term "Implant, Auditory Brainstem" and reviewing all reports with the basic search term "Brainstem Implant". All collected reports were individually reviewed. RESULTS: A total of 265 individual patient reports were reviewed, of which 55 reports met inclusion criteria. Reports regarding audiologic outcome included failure to provide hearing benefit (n = 27), implant failure/device malfunction (n = 10), and device non-use (n = 6). Postoperative complications included local skin infection (n = 3), CSF leak (n = 3), elevated ICP (n = 1), surgical site dehiscence (n = 1), swelling (n = 1), seroma formation requiring drainage (n = 1), and meningitis (n = 2). Two patients had dislodged magnets during 1.5 Tesla MRI acquisition. There were 35 instances of full explantation of the device and 1 partial removal; 13 patients had a new device implanted following explantation. CONCLUSIONS: Poor hearing results, device failure, and non-use were commonly reported causes for explanation in this analysis. This information can aid physicians in counseling patients and family members and managing device expectations.

One Anastomosis Gastric Bypass as Revisional Surgery Following Sleeve Gastrectomy: A Systematic Review and Meta-Analysis.

BACKGROUND: Although sleeve gastrectomy (SG) is the most performed metabolic and bariatric surgery (MBS) worldwide, some patients require conversional procedures due to weight recurrence or late complications. Recently, one-anastomosis gastric bypass (OAGB) gained popularity as a viable option to address those problems. The aim of this meta-analysis is to assess the safety and efficacy of conversional OAGB after primary SG in the management of patients with obesity. METHODS: Cochrane, Embase, PubMed, Scopus, and Web of Science were searched for articles from their inception to February 2023 by two independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) system. The review was registered prospectively with PROSPERO (CRD42023403528). RESULTS: From 1,117 studies screened, twenty studies met the eligibility criteria, with a total of 1,057 patients with obesity undergoing conversional OAGB after primary SG. The mean age ranged from 28.2 to 49.5 years, and 744 patients (75.2%) were women. At one year after revisional OAGB, the pooled mean percent excess weight loss (%EWL) was 65.2% (95%CI: 56.9, 73.4, I2 = 97%). The pooled mean %EWL after conversional OAGB was 71.1% (95%CI: 62.2, 80.0, I2 = 90%) at two years and 71.6% (95%CI: 61.0, 82.2, I2 = 50%) at five years. Additionally, resolution rates of diabetes and hypertension were 65.4% (95%CI: 0.522, 0.785, I2 = 65%) and 58.9% (95%CI: 0.415, 0.762, I2 = 89%), respectively. CONCLUSIONS: Our meta-analysis demonstrated OAGB as an effective conversional procedure after primary SG in terms of weight loss and obesity-associated medical problems for selected patients. Despite the promising results, further randomized controlled studies with larger sample sizes and more extended follow-up periods are necessary to determine if the OAGB is the best conversional surgery after SG.

Virtual surgical planning for mandibular reconstruction in an abbreviated admission pathway.

OBJECTIVES: Virtual Surgical Planning (VSP) creates individualized surgical plans for free flap reconstruction of mandibular defects. Prior studies indicate that VSP can offer cost benefits due to reduced operative time and length of stay (LOS). We assessed the impact of VSP in the context of a validated postoperative abbreviated LOS clinical pathway. METHODS: This study assessed patients undergoing VSP vs conventional fibular free flap reconstruction for mandibular defects (12/2015-10/2020) and their operative time, ischemia time, and LOS were evaluated. RESULTS: Forty-four patients underwent VSP reconstruction, while 52 patients underwent conventional reconstruction for mandibular defects. VSP was associated with significantly lower total operative time (6 h and 57 mins vs 7 h and 54 mins, p = 0.011), but not length of stay or ischemia time. Total OR time was significantly increased with increasing number of segments needed in both the VSP group (p = 0.002) and the conventional group (p = 0.015). CONCLUSION: Shorter operative times and LOS have been attributed to the use of VSP in free tissue transfers. It is argued that these reductions offset the added cost of VSP. Our study indicates that there is no cost benefit for VSP utilization due to a significantly reduced operative time with no impact on length of admission in an abbreviated admission clinical pathway following free tissue transfer.

Antimicrobial effect of chamomile-containing over-the-counter ear and eye drops.

Chamomile (Matricaria chamomilla) is a plant with known antimicrobial, anti-inflammatory, and analgesic properties. Homeopathic drops containing chamomile extract are often used for ear pain and chronic ear infections. We aimed to evaluate the antimicrobial effect of over-the-counter eardrops containing chamomile against organisms causing bacterial conjunctivitis and otitis externa. Liquid cultures of Streptococcus aureus and Pseudomonas aeruginosa were exposed to increasing concentrations of eardrops containing chamomile extract. Liquid cultures of S. aureus and Streptococcus pneumoniae were exposed to increasing concentrations of chamomile eye drops for 5, 10, 15, and 45 min. Colony forming units (CFUs) were assessed after 18 h. Viability assays for these organisms were performed using the resazurin microdilution assay. We observed a reduction in the number of P. aeruginosa CFUs when the bacteria were exposed to any of the three concentrations of the chamomile drops as early as 5 min, with maximal reduction upon exposure to the 30% concentration at 45 min. Reduction in S. aureus CFUs, on the other hand, was observed for all three concentrations as maximal in the 5 min of exposure. We observed a marked reduction in the number of S. aureus CFUs upon exposure to any of the three preparations of chamomile-containing eye drops, which was almost immediate at 10% concentration. Streptococcus pneumoniae reduction happened at 5 min and continued through the 45-min observation period for all three concentrations. Our findings suggest that over-the-counter ear drops containing chamomile extract could potentially be used as a non-prescription treatment for mild cases of otitis externa and bacterial conjunctivitis.

Multidrug-Resistant Enterococcal Infection in Surgical Patients, What Surgeons Need to Know.

Enterococci are organisms that can be found in the normal intestinal and skin microbiota and show remarkable ability to acquire antibiotic resistance. This is an enormous challenge for surgeons when faced with surgical site infections caused by multidrug-resistant (MDR) Enterococci. Due to an increase in the prevalence of MDR Enterococcus within the last few decades, there has been a major decrease in therapeutic options, because the majority of E. faecium isolates are now resistant to ampicillin and vancomycin and exhibit high-level resistance to aminoglycosides, traditionally three of the most useful anti-enterococcal antibiotics. There is limited data regarding the magnitude and pattern of multidrug resistance among the enterococcal genus causing surgical site infections in hospitalized patients. The scope of the review is to summarize the most recent findings in the emergence of postoperative MDR Enterococci and discuss recent mechanisms of resistance and the best treatment options available.
