Canadian women in otolaryngology: head and neck surgery part 2-challenges in family planning, fertility, and lactation

BACKGROUND

Previous literature demonstrates that female surgeons face difficulties in family planning, meeting breastfeeding goals, leadership and advancement opportunities. These issues have received limited attention in Canadian surgeons despite different maternity leave patterns compared to the general Canadian population. We sought to describe the experience of otolaryngologist-head and neck surgeons in family planning, fertility, and lactation and to identify the role of gender and career stage in these experiences.

METHODS

A RedCAP^® survey was disseminated to Canadian otolaryngology-head and neck surgeons and residents from March to May of 2021 through social media and the national listserv. This survey examined fertility, pregnancy losses, and infant feeding. Major independent variables include gender and career stage (faculty and resident). Dependent variables include respondent experiences with fertility, number of children, and length of parental leave. Responses were tabulated and presented descriptively to communicate the experience of Canadian otolaryngologists. Further, statistical comparisons such as chi-square and t-tests were employed to identify relationships between these variables. Thematic analysis was conducted for narrative comments.

RESULTS

We received 183 completed surveys (22% response rate). 54% of females versus 13% of males agreed that career influenced their ability to have children (p = 0.002). 74% of female respondents without children have concerns about future fertility compared to 4% of men (p < 0.001). Furthermore, 80% of women versus 20% of men have concerns about future family planning (p < 0.001). The average maternity leave was 11.5 weeks for residents, and 22.2 weeks for staff. Additionally, significantly more women than men stated that maternity leave impacted advancement opportunities (32% vs. 7%) and salary/remuneration (71% vs. 24%) (p < 0.001). Over 60% of those choosing to pump breastmilk at work reported having inadequate time, space, and breastmilk storage. In total, 62% of breastfed infants were receiving breastmilk at 1 year.

CONCLUSION

Canadian female otolaryngologists-head and neck surgeons face challenges in family planning, ability to conceive, and breastfeeding. Focused effort is required to provide an inclusive environment that helps all otolaryngologists-head and neck surgeons achieve both their career and family goals, regardless of gender or career stage.

Canadian Women in Otolaryngology-Head and Neck Surgery part 1: the relationship of gender identity to career trajectory and experiences of harassment

INTRODUCTION

Women in surgical specialties face different challenges than their male peers. However, there is a paucity of literature exploring these challenges and their effects on a Canadian surgeon's career.

METHODS

A REDCap® survey was distributed to Canadian Otolaryngology-Head and Neck Surgery (OHNS) staff and residents in March 2021 using the national society listserv and social media. Questions examined practice patterns, leadership positions, advancement, and experiences of harassment. Gender differences in survey responses were explored.

RESULTS

183 completed surveys were obtained, representing 21.8% of the Canadian society membership [838 members with 205 (24.4%) women]. 83 respondents self-identified as female (40% response rate) and 100 as male (16% response rate). Female respondents reported significantly fewer residency peers and colleagues identifying as their gender (p < .001). Female respondents were significantly less likely to agree with the statement "My department had the same expectations of residents regardless of gender" (p < .001). Similar results were observed in questions about fair evaluation, equal treatment, and leadership opportunities (all p < .001). Male respondents held the majority of department chair (p = .028), site chief (p = .011), and division chief positions (p = .005). Women reported experiencing significantly more verbal sexual harassment during residency (p < .001), and more verbal non-sexual harassment as staff (p = .03) than their male colleagues. In both female residents and staff, this was more likely to originate from patients or family members (p < .03).

DISCUSSION

There is a gender difference in the experience and treatment of OHNS residents and staff. By shedding light on this topic, as a specialty we can and must move towards greater diversity and equality.

What is the optimal outcome after endoscopic sinus surgery in the treatment of chronic rhinosinusitis? A consultation of Canadian experts

OBJECTIVES

Many experts feel that in the absence of well-defined goals for success, they have an easier time identifying failure. As success ought to not be defined only by absence of failure, we aimed to define optimal outcomes for endoscopic sinus surgery (ESS) in chronic rhinosinusitis (CRS) by obtaining expert surgeon perspectives.

METHODS

A total of 12 surgeons participated in this targeted consultation. Face to face semi-structured interviews were performed with expert surgeons in the field of CRS and ESS. General impressions and personal definitions of acceptable operative success and optimal operative outcomes were compiled and summarized.

RESULTS

According to an expert survey, patients' main objectives are an improvement in their chief complain, a general improvement in quality of life (QoL), and a better overall symptomatic control. The most important aspects of endoscopy for defining a successful intervention were an adequate mucus circulation, a healthy mucosa, minimal edema, and patency of all explored cavities or ostia. In the assessment of surgical outcomes, it was determined that both objective and patient reported data must be carefully examined, with more attention given to subjective outcomes.

CONCLUSIONS

According to data gathered from a Canadian expert consultation, a definition of success must be based on both subjective data and nasal endoscopy. We propose to define an acceptable outcome as either a subjective improvement of at least the minimal clinically improvement difference of a validated patient reported outcome questionnaire, along with a satisfactory endoscopic result (1) or a complete subjective resolution with a sub-optimal endoscopy (2).

CSO (Canadian Society of Otolaryngology - Head & Neck Surgery) position paper on rhinologic and skull base surgery during the COVID-19 pandemic

Healthcare services in many countries have been partially or completely disrupted by the Coronavirus (COVID-19) pandemic since its onset in the end of 2019. Amongst the most impacted are the elective medical and surgical services in order to conserve resources to care for COVID-19 patients. As the number of infected patients decrease across Canada, elective surgeries are being restarted in a staged manner. Since Otolaryngologists - Head & Neck Surgeons manage surgical diseases of the upper aerodigestive tract where the highest viral load reside, it is imperative that these surgeries resume in a safe manner. The aim of this document is to compile the current best evidence available and provide expert consensus on the safe restart of rhinologic and skull base surgeries while discussing the pre-operative, intra-operative, and post-operative care and tips. Risk assessment, patient selection, case triage, and pre-operative COVID-19 testing will be analyzed and discussed. These guidelines will also consider the optimal use of personal protective equipment for specific cases, general and specific operative room precautions, and practical tips of intra-operative maneuvers to optimize patient and provider safety. Given that the literature surrounding COVID-19 is rapidly evolving, these recommendations will serve to start our specialty back into elective rhinologic surgeries over the next months and they may change as we learn more about this disease.

Azithromycin in high-risk, refractory chronic rhinosinusitus after endoscopic sinus surgery and corticosteroid irrigations: a double-blind, randomized, placebo-controlled trial

BACKGROUND

Refractory chronic rhinosinusitis (CRS) remains a significant burden for patients, often leaving them with few therapeutic options that provide low-morbidity, long-term, and meaningful symptomatologic and endoscopic disease improvement. Macrolides have long been thought to offer both an immunomodulatory and antimicrobial effect. Our objective was to evaluate the efficacy of low-dose, long-term azithromycin in a carefully selected high-risk population failing appropriate medical therapy of budesonide nasal irrigations (BNIs) and endoscopic sinus surgery (ESS).

METHODS

A double-blind, randomized, placebo-controlled trial was completed in a single tertiary-care center assessing the addition of 250 mg azithromycin, 3 times per week for 16 weeks, in adults failing ESS and high-volume BNIs. Associated comorbidities, as well as symptomatologic, microbiologic, and serologic values, were systematically collected.

RESULTS

A total of 128 patients were enrolled and underwent ESS followed by BNI. At the 4-month post-ESS visit, 48 patients showed disease persistence and were randomized to azithromycin or placebo. Overall, azithromycin, when compared with placebo, did not show a statistically significant difference in disease clearance (54% vs 33%, respectively; p = 0.146), although patients with disease clearance who were on azithromycin showed significantly better 22-item Sino-Nasal Outcome Test score improvements than patients on placebo (18 vs -0.9, respectively; p = 0.046). In a subgroup analysis excluding aspirin-exacerbated respiratory disease (AERD) patients, azithromycin significantly improved disease clearance when compared with placebo (71% vs 35%, respectively; p = 0.031), with a number needed to treat of 3 (2.8).

CONCLUSION

Low-dose azithromycin is a therapeutic option with few side effects. Its use can show favorable clinical outcomes in this difficult-to-treat population, especially if patients are AERD-negative.

Staphylococcus aureus on Sinus Culture Is Associated With Recurrence of Chronic Rhinosinusitis After Endoscopic Sinus Surgery

Objectives: Identify whether identification of S. aureus on conventional culture is a predictor of success or failure after ESS followed by budesonide nasal irrigations (BUD) in chronic rhinosinusitis (CRS) patients at high risk of recurrence.

Methodology: Prospective clinical trial including 116 patients from a tertiary care center at high-risk of disease recurrence following ESS+BUD. Blood samples, microbial swabs, and SNSS/SNOT-22 were taken on the day of surgery (Visit-1) and 4 months postoperatively (Visit-2). Outcomes were evaluated using symptoms and mucosal status as assessed by the Lund-Kennedy endoscopic score.

Results: Seventy-five patients (69.4%) attained SNOT-22 MCID or higher. (Mean = 33.4, range 9–75). Objective documentation of recurrence of disease, as defined by combined endoscopic/symptomatic criteria, was noted in 58/116 patients (50%). Revision surgery was associated with a significantly higher rate of disease recurrence (60.0 vs. 28.0%; p < 0.001). Culture for Staphylococcus aureus was associated with disease recurrence, preoperatively and at 4 months post-surgery (p = 0.020; p < 0.001). This was restricted to post-operative cultures in the revision group (10.0 vs. 48.8%; p < 0.001). Other factors associated with poor outcome included intolerance to non-steroidal anti-inflammatory drugs (NSAID) (p = 0.036). Significantly higher Lund-Kennedy scores in the recurrence groups despite similar symptom intensity, emphasizing the importance of considering objective outcome in addition to patient-reported ones.

Conclusion: Patients undergoing revision ESS are at high risk of disease recurrence, even when budesonide irrigations are used post operatively. Presence of S. aureus on culture pre-operatively or at 4 months post-ESS is associated with a negative outcome. This suggests that S. aureus negatively influences outcome, possibly via a number of mechanisms, including interactions with the (i) immune system, (ii) regeneration and repair of the sinus epithelium, or (iii) via interference with the sinus microbiome. This suggests that S. aureus may be a simple and inexpensive biomarker for disease severity and indicates a clear need to better appreciate S. aureus on how it contributes mechanistically to disease development and persistence in order to develop targeted therapeutic strategies.

Patient and Public Outreach Initiatives in Chronic Rhinosinusitis from the Canadian Sinusitis Working Group: Support for Affected Patients and Extending an Understanding of CRS to the General Public

Chronic rhinosinusitis is an important disease entity that affects patients worldwide, yet there is limited public awareness regarding the disease. The Canadian Rhinosinusitis Working Group, a group of diverse medical professionals, has made a multitude of efforts to help improve the health literacy of patients and important stakeholders, as well as the quality of life of patients with chronic rhinosinusitis. This review will aim to outline these initiatives.

Dietary modifications for refractory chronic rhinosinusitis? Manipulating diet for the modulation of inflammation

BACKGROUND

An endotype of chronic rhinosinusitis (CRS) refractory to medical and surgical management is characterized by persistent T-helper 1/T-helper 17 inflammation of the sinus mucosa, which potentially facilitates colonization with dysbiotic microbial flora. Dietary interventions that target reduction of systemic inflammation are increasingly recommended as adjuncts to ongoing medical therapy in chronic disorders with a strong inflammatory component, such as cardiac disease, diabetes, and metabolic syndrome. Inflammation-reducing dietary modifications may thus be of benefit in patients with refractory CRS (RCRS).

OBJECTIVE

To identify nonpharmacologic approaches that implicate modification of dietary factors, potentially reducing systemic level of inflammation in RCRS.

METHODS

A systematic review of the literature was undertaken to identify dietary strategies for reducing inflammation in metabolic syndrome, diabetes, and cardiac disease. Mechanistic-based strategies for reducing systemic inflammation were identified and categorized to identify potential therapeutic avenues, which would be applicable to RCRS.

RESULTS

Principal mechanisms for altering inflammation at the systemic level via dietary manipulation center around (1) increased consumption of foods with anti-inflammatory properties, and (2) modulation of the gut microbiome to reduce short-chain fatty acid secretion by dysbiotic gut flora. Recommended dietary modifications to reduce systemic markers of inflammation or to improve RCRS include alteration of macronutrient intake, alterations in consumption of meat and fats, consumption of prebiotics and probiotics, and a low-salicylate diet in the context of aspirin-exacerbated respiratory disease.

CONCLUSION

Dietary modifications may offer a potential nonpharmacologic means of reducing inflammation in patients with RCRS and hence may represent a complementary adjunct to existing medical therapies. Additional prospective studies are required to further validate the concept of dietary modifications in patients with RCRS to support the findings.

Local molecular analysis of indeterminate thyroid nodules

BACKGROUND

Thyroid nodules are common but only a minority are malignant. Molecular testing can assist in helping determine whether indeterminate nodules are suspicious for malignancy or benign. The objective of the study was to determine if the analysis of mutations (BRAF, NRAS, KRAS and HRAS) using readily available molecular techniques can help better classify indeterminate thyroid nodules.

METHODS

A retrospective cohort of consecutive patients undergoing diagnostic thyroid surgery were analyzed for the presence or absence of specific mutations known to be associated with thyroid malignancy in FNA samples. Markers chosen were BRAF, NRAS, KRAS and HRAS. All were locally available and currently in use at our centre for other clinical indications. Results from the molecular analysis were then compared to the histopathology from thyroidectomy specimens to determine the sensitivity and specificity of these molecular techniques to classify indeterminate thyroid nodules.

RESULTS

Sixty consecutive patients with indeterminate FNAs were recruited. Twenty-three patients had malignant tumors while 37 specimens were benign. Multiple different mutations were identified in the FNA samples. Overall 18 cases had a positive mutation (10 malignant and 8 benign). The sensitivity of BRAF, HRAS, KRAS, and NRAS was 8.7, 8.7, 8.7, and 17.4 respectively while the specificity was100, 83.7, 100 and 94.6.

CONCLUSION

While molecular analysis remains promising, it requires further refinement. Several markers showed promise as good "rule-in" tests.

Humoral Primary Immunodeficiencies in Chronic Rhinosinusitis

Chronic rhinosinusitis (CRS) may be the primary presenting symptom for primary immunodeficiencies (PID). PID can affect the humoral or the cellular immune system. This paper provides an overview of PID which affect the humoral immune system, with details around the diagnostic criteria, the epidemiology, the subtypes, the clinical manifestations, underlying molecular mechanisms, methods to screen for PID and the management of CRS in the context of PID. A high clinical suspicion of PID is required when assessing patients with CRS who are refractory to maximal medical therapy.

Squeeze bottle versus saline spray after endoscopic sinus surgery for chronic rhinosinusitis: a pilot multicentre trial

BACKGROUND

There is a need for controlled trials to guide the perioperative management of patients undergoing endoscopic sinus surgery (ESS). The authors performed a pilot multicenter trial to compare two types of saline delivery devices in this population.

METHODS

Patients were randomized to high volume saline irrigation with a squeeze bottle and low volume saline spray after ESS in patients with chronic rhinosinusitis (CRS). Surgeons were blinded to treatment, and one-month postoperative scores for sinonasal outcomes [Sinonasal Outcome Test-22 (SNOT-22)] scale, nasal and sinus symptom score (NSS), and perioperative sinus endoscopy (POSE) scale were compared with preoperative scores.

RESULTS

Nine centers provided data for 86 patients. All three outcomes measures improved significantly for both groups. Saline spray: SNOT-22 48.8 versus. 23.7, treatment effect 25.1 (95% confidence interval [CI], 17.9-32.2), POSE 21.1 versus. 8.4, treatment effect 12.7 (95% CI, 9.2-16.1), and NSS 8.2 versus 5.0, treatment effect 3.1 (95% CI, 1.4-4.9) pre- and postoperatively, respectively (all p < 0.0001). Squeeze bottle: SNOT-22 49.5 versus 23.6, treatment effect 25.9 (95% CI, 20.3-31.6), POSE 18.6 versus 9.2, treatment effect 9.3, (95% CI 6.7-12.0), and NSS 9.0 versus 5.7, treatment effect 3.3 (95% CI, 2.3-4.3) pre- and postoperatively, respectively (all p < 0.0001). Analysis of variance did not identify a difference between the two treatment groups. Subgroup analysis based on preoperative disease severity did not change the nonassociation of saline bottle with outcome measures. Post hoc sample size calculation determined that 176 patients is required to detect an 8.9-point difference in SNOT-22 scores.

CONCLUSION

In this pilot multicenter trial examining patients with chronic rhinosinusitis undergoing ESS, both squeeze bottle and saline spray showed significant improvement in SNOT-22, POSE, and NSS scores at one-month postoperatively. Because the study was nonpowered, we cannot rule out a potential difference between the two treatment groups.

Treatment of Aspirin Exacerbated Respiratory Disease with a Low Salicylate Diet

Objective

Aspirin exacerbated respiratory disease (AERD) is comprised of aspirin/acetylsalicylic acid (ASA) sensitivity, bronchial asthma, and nasal polyposis. Treatment of this condition is challenging and may include topical/systemic steroids, endoscopic sinus surgery, and/or aspirin desensitization.

Study Design

A prospective crossover pilot study (n = 10) was conducted in which patients were randomized into either of 2 groups with 6 weeks of regular diet (R) or 6 weeks of a low salicylate diet (LS).

Setting

The study was conducted in a tertiary otolaryngology clinic.

Subjects

Patients with AERD were enrolled in the study.

Methods

Subjective (Sino-nasal Outcome Test-22 [SNOT-22], Nasal Sinus Symptom Scale [NSSS], and the Asthma Control Questionnaire-7 [ACQ-7]) and objective outcome instruments (Peri-Operative Sinus Evaluation [POSE] and Lund-Kennedy Endoscopic Score [LKES]) were used to evaluate patients at baseline, 6 weeks (at crossover), and 12 weeks.

Results

Wilcoxon rank sum tests demonstrated that patients on the low salicylate diet had improved scores compared to their regular diet when evaluated by 4 of the 5 outcome measures (SNOT-22 pLS = 0.0059, NSSS pLS = 0.0195, LKES pLS = 0.0039, POSE pLS = 0.005).

Conclusion

Results of the pilot study indicate that implementation of a low salicylate diet improves the nasal symptoms and nasal endoscopy findings of individuals with AERD. Further research is required to support these findings.

Intra-thyroidal hemangioma--a rare congenital anomaly: case presentation and literature review

Infantile hemangiomas (IH) present and evolve in a predictable way. In certain cases, however, they can be of clinical significance. IHs in the airway can cause significant respiratory distress. We present the first reported case of an intrathyroidal hemangioma to cause significant respiratory distress, which was successfully treated with propranolol and dexamethasone. A review of the literature was also performed.

Smoking Cessation Interventions and Cessation Rates in the Oncology Population

Objectives

To evaluate tobacco smoking cessation interventions and cessation rates in the oncology population through a systematic review and meta-analysis.

Data Sources

The literature was searched using PubMed, Google Scholar, Medline, EMBASE, and the Cochrane Library (inception to October 2012) by 3 independent review authors.

Review Methods

Studies were included if they were randomized controlled trials (RCTs) or prospective cohort (PCs) studies evaluating tobacco smoking cessation interventions with patients assigned to a usual care or an intervention group. The primary outcome measure was smoking cessation rates. Two authors extracted data independently for each study. When applicable, disagreements were resolved by consensus.

Results

The systematic review identified 10 RCTs and 3 PCs. Statistical analysis was conducted using StatsDirect software (Cheshire, UK). Pooled odds ratios (ORs) for smoking cessation interventions were calculated in 2 groups based on follow-up duration. The therapeutic interventions included counseling, nicotine replacement therapy, buproprion, and varenicline. Smoking cessation interventions had a pooled odds ratio of 1.54 (95% confidence interval [CI], 0.909-2.64) for patients in the shorter follow-up group and 1.31 (95% CI, 0.931-1.84) in the longer follow-up group. Smoking cessation interventions in the perioperative period had a pooled odds ratio of 2.31 (95% CI, 1.32-4.07).

Conclusion

Our systematic review and meta-analysis demonstrate that tobacco cessation interventions in the oncology population, in both the short-term and long-term follow-up groups, do not significantly affect cessation rates. The perioperative period, though, may represent an important teachable moment with regard to smoking cessation.

YouTube as a Source of Pediatric Tonsillectomy Information

Objective: Tonsillectomy is a common surgery performed on pediatric patients. Patients and their caregivers may search the Internet for information related to this procedure, and YouTube is a popular Web site that they may consult. We investigated YouTube as an information source on pediatric tonsillectomy.

Method: YouTube was searched on February 17, 2012, for videos containing relevant information about tonsillectomies in pediatric patients using the keywords pediatric tonsillectomy, tonsillectomy and tonsil surgery. Non-English videos were excluded. Two physician reviewers watched each video and assessed for content (useful, misleading, personal experience). The StatsDirect software will analyze measures.

Results: The search for each keyword identified over 2555 videos (pediatric tonsillectomy = 91, tonsillectomy = about 1800, tonsil surgery = 664). The first 200 videos were screened for each keyword on the assumption that most users would not go beyond the first 10 pages. Therefore, 491 videos were screened for inclusion and exclusion criteria, and duplicates were removed. At the time of abstract submission, final data analysis was not yet available. Outcomes included content assessment and characteristics, and video total viewership, number of days since upload, total duration, viewer rating, and source of upload. Reviewer degree of agreement and relevant statistical analysis will be reported.

Conclusion: YouTube has a substantial number of videos on pediatric tonsillectomy with a variety of content ranging from useful to misleading. Health care professionals must recognize the potential influence that these user-generated video Web sites may have on the attitudes of patients and their caregivers.

Smoking Cessation in Cancer Patients: A Systematic Review

Objective: Comprehensive treatment plans for oncology patients including tobacco smoking cessation interventions are essential, as smoking after the diagnosis of a smoking-related cancer negatively impacts many aspects of treatment in this patient population. The primary objective was to evaluate, through a systematic review, smoking cessation interventions and cessation rates in cancer patients.

Method: The literature was searched using Medline, EMBASE, Google Scholar, and the Cochrane Library (inception to September 2011) by 3 independent review authors. Included studies described tobacco smoking cessation interventions with patients randomized to usual care or an intervention. The primary outcome measure was cessation rates. Two authors extracted data independently, and disagreements were resolved by consensus.

Results: Eight randomized control trials (RCTs) investigating smoking cessation interventions in the oncology patient population were identified. Pooled relative risks were calculated from 2 groups of RCTs of smoking cessation interventions based on follow-up duration. In both groups, the pooled relative risk did not suggest a statistically significant improvement in tobacco cessation compared to usual care. However, a subgroup analysis looking at newer combination interventions within the last 10 years yielded a statistically significant difference in smoking cessation rates.

Conclusion: Despite the importance of smoking cessation in oncology patients, there are a paucity of studies. The review suggests that newer combination interventions involving both nonphamacological and pharmacological approaches, in the last decade, yield a statistically significant difference in smoking cessation rates compared to usual care.

Evaluating smoking cessation interventions and cessation rates in cancer patients: a systematic review and meta-analysis

Background. Tobacco smoking cessation interventions in the oncology population are an important part of comprehensive treatment plan. Objectives. To evaluate through a systematic review smoking cessation interventions and cessation rates in cancer patients. Search Strategy. The literature was searched using Medline, EMBASE, and the Cochrane Library (inception to November 2010) by three independent review authors. Selection Criteria. Studies were included if tobacco smoking cessation interventions were evaluated and patients were randomized to usual care or an intervention. The primary outcome measure was cessation rates. Data Collection and Analysis. Two authors extracted data independently for each paper, with disagreements resolved by consensus. Main Results. The systematic review found eight RCTs investigating smoking cessation interventions in the oncology patient population. Pooled relative risks were calculated from two groups of RCTs of smoking cessation interventions based on followup duration. In both groups, the pooled relative risk did not suggest a statistically significant improvement in tobacco cessation compared to usual care. Conclusions. Our review demonstrates that recent interventions in the last decade which are a combination of non-pharmacological and pharmacological approaches yield a statistically significant improvement in smoking cessation rates compared to usual care.

Purely endoscopic transsphenoidal surgery versus traditional microsurgery for resection of pituitary adenomas: systematic review

OBJECTIVE

To determine, in a systematic review, whether purely endoscopic transsphenoidal resection of pituitary adenomas offers improved outcomes and decreased complications compared to the traditional microscopic approach.

DESIGN

Systematic review.

SETTING

The literature was searched using Medline, EMBASE, and the Cochrane Library (inception to October 2009) by two independent review authors.

METHODS

Studies were included if they compared the two surgical approaches for the management of pituitary adenomas and at least one main outcome measure.

MAIN OUTCOME MEASURES

Gross tumour resection (GTR), recurrence, visual field improvement, hormone resolution, mean blood loss, mean operative time, mean hospital length of stay, cerebrospinal fluid (CSF) leak, hormone deterioration, vision deterioration, nasal complications, meningitis, and death.

RESULTS

Ten studies met the inclusion criteria (one prospective and nine retrospective) and involved 687 patients. The purely endoscopic approach was associated with less mean blood loss, shorter hospital stays and operative times, and fewer nasal complications. There was also a trend toward better GTR and decreased incidence of postoperative diabetes insipidus. However, a higher incidence of postoperative CSF leak was also noted with the endoscopic approach. Other outcomes and complication rates appeared to be similar between the two groups.

CONCLUSIONS

Purely endoscopic transsphenoidal resection of pituitary adenomas seems to be safe and efficacious when compared to the traditional microscopic approach and may offer some benefit.

Cervical esophageal duplication cyst: case report and review of the literature

Cervical esophageal duplication cysts are rare congenital anomalies that can be successfully managed surgically. These anomalies are rare causes of upper airway obstruction. We present here a case of a cervical esophageal duplication cyst in an infant, along with a review of the literature concerning this anomaly.
