Subglottic Stenosis After Endonasal Resection of Juvenile Nasopharyngeal Angiofibroma.

Subglottic stenosis (SGS), the narrowing of the upper trachea, can be an acquired condition in pediatric patients. Presenting with varying degrees of dyspnea and stridor, acquired SGS is most commonly due to intubation. Airway stenosis is often not considered a surgical complication, and no literature on acquired SGS after endoscopic sinus surgery exists. We present a unique case of a 13-year-old male with juvenile nasopharyngeal angiofibroma (JNA), who developed SGS in the setting of progressive dyspnea six weeks after endonasal resection of his mass. He required urgent intubation prior to preoperative embolization and endonasal surgery, which prolonged his total intubation period. After the patient was found to have acquired SGS, he eventually required serial dilation to treat his stenosis. The presentation and operative course of this patient, along with images and pathologic findings, are discussed. Based on an extensive literature review of PubMed, Medline, and Google Scholar, there have been no cases discussing SGS development post-intubation after endonasal surgery or in association with JNA. Acquired SGS can present as a life-threatening airway obstruction in pediatric patients. With the rise of endoscopic skull base surgery and the prevalence of JNA, this case study sheds light on the detection and management of SGS post-operatively.

Post-Intensive Care Syndrome Among Survivors in a Safety Net Hospital in South Bronx: A Comparison of Patients With and Without Coronavirus Disease 2019.

Comparison of post-intensive care syndrome between critically ill survivors with or without coronavirus disease 2019 (CovP and CovN, respectively) showed that fewer CovP were able to return to work full time at >1 year and none at <1 year after discharge and that the majority of CovP survivors were able to work part time during both evaluation periods compared to CovN.

Does Time of Administration of Intravenous Ketorolac Impact Pain-Related Outcomes in Dacryocystorhinostomy?

PURPOSE: An emerging body of evidence indicates that intravenous ketorolac (IVK) reduces pain scores and the requirement for opioid analgesics in a variety of oculofacial procedures. This study was performed to assess the impact of timing of IVK administration on these benefits after external dacryocystorhinostomy (DCR). METHODS: Patients were randomized to receive IVK before (n = 50), during (n = 50), or after DCR (n = 50). An additional cohort of control patients did not receive the medication (n = 50). Postoperative pain was measured via a visual analog scale immediately after DCR on the first day after surgery (POD1). Additionally, the need for opioid analgesics to control pain was recorded. Statistical analyses were performed via a dedicated computerized software package. RESULTS: Immediately after surgery, mean pain scores were 5.26 for control patients, and 2.30, 2.44, and 2.36 for patients that received IVK pre-, intra-, and post-operatively, respectively (p < .001 for each condition, as compared to controls). On POD1, mean pain scores were 3.52 for control patients and 1.38, 1.32, and 1.28 for patients that received IVK pre-, intra-, and post-operatively, respectively (p < .001 for each condition, as compared to controls). 28% of control patients required postoperative opioid analgesics, as compared to 6%, 4%, and 4% among patients that received IVK pre-, intra-, and postoperatively, respectively (p < .05 for each condition, as compared to controls). CONCLUSIONS: IVK significantly reduces postoperative pain and the requirement for opioid analgesics after DCR, regardless of the timing of administration. This benefit appears to extend into the first postoperative day.

The Supportive Role of Provocative Maneuvers and Impedance Clearance in Detecting Ineffective Esophageal Motility.

Background: Ineffective esophageal motility (IEM) is one of the most common esophageal motility disorders. However, the definition of IEM has evolved. Chicago classification version 4.0 (CCv4.0) made IEM parameters more stringent with greater than 70% of ineffective wet swallows (WS) necessary to diagnose conclusive IEM. Of the ineffective swallows, 50-70% are deemed "inconclusive cases". This study sought to determine whether provocative maneuvers, including multiple rapid swallows (MRS) and apple viscous swallows (AVS), and impedance clearance can provide supportive information for inconclusive IEM disorders based on CCv4.0. Methods: Esophageal motility data on 100 patients were analyzed. All patients completed WS and at least one additional swallow test (MRS and/or AVS). Patients were classified as having conclusive IEM, inconclusive IEM, or normal motility. IEM features detected on MRS/AVS and incomplete bolus clearance were recorded. Percentage of agreement between IEM features and incomplete bolus clearance was calculated for each motility group. Results: Ten patients had conclusive IEM, nine had inconclusive IEM, and 32 had normal motility. There was 70% agreement between IEM features and incomplete bolus clearance with conclusive IEM, 33% agreement with inconclusive IEM, and 9% agreement with normal motility. There was significantly more agreement in the conclusive and inconclusive IEM groups than in the normal motility group (P = 0.0003). Conclusions: Combinational follow-up testing with provocative maneuvers and impedance clearance may assist with risk stratification of IEM patients and assist in further management of inconclusive IEM. MRS and AVS can detect unique IEM features that may help with preoperative management of inconclusive IEM.

A comparison of primary laser versus laser after anti-vascular endothelial growth factor for type 1 retinopathy of prematurity.

PURPOSE: To compare characteristics of laser treatment for high-risk type 1 retinopathy of prematurity (ROP) in eyes treated with primary laser versus laser after an initial treatment with intravitreal anti-vascular endothelial growth factor (anti-VEGF). METHODS: The medical records of consecutive patients at a single academic institution treated for type 1 ROP before 36 weeks' postmenstrual age with primary laser versus laser after initial treatment with anti-VEGF were reviewed retrospectively. Outcome measures were laser spot number, mean laser power, total laser energy (Joules), and retinal vascularization to the nasal ora at time of laser treatment. RESULTS: Compared with the 46 eyes treated with primary laser, the 46 eyes treated with laser after anti-VEGF required fewer spots (mean, 775 vs 1418 [P < 0.01]), less power (182 vs 223 mW [P < 0.01]), and less total energy (27 vs 61 Joules [P < 0.01]), and showed greater vascularization to the nasal ora at the time of laser treatment (47.8% vs 6.5% [P < 0.01]). CONCLUSIONS: In our study cohort, laser after initial anti-VEGF treatment may have allowed for greater retinal vascularization and been less destructive than primary laser for high-risk type 1 ROP.

Advancing high-resolution manometry: evaluating the use of multiple rapid swallows versus apple viscous swallows in clinical practice.

BACKGROUND: High-Resolution Manometry (HRM) with provocative maneuvers, such as Multiple Rapid Swallows (MRS) and Apple Viscous Swallows (AVS), is commonly utilized to diagnose esophageal disorders. Increasing standardization in HRM protocol can help save time and reduce patient discomfort. This study assesses AVS and MRS to determine their respective benefits and limitations. METHODS: Retrospective reviews were performed on 100 patients to analyze their AVS and/or MRS results. Parameters included abnormal motility patterns, tolerance, and DCI. Diagnostic benefits from MRS and AVS were assessed. Based on the previous studies, additional benefit from MRS was defined as detection of good peristaltic reserve, weak peristaltic reserve, or an abnormal motility/pressurization pattern. Additional benefit from AVS was defined as detection of IEM features or abnormal motility/pressurization pattern. RESULTS: When patients completed both MRS and AVS (n = 70), MRS provided additional benefit in assessing 36% of patients, while AVS provided additional benefit in 19% of patients (p < 0.0001). Furthermore, MRS detected significantly more abnormal motility/pressurization patterns than AVS (27% MRS; 8% AVS; p = 0.0005). Two unique strengths of AVS were higher tolerance for test completion (p = 0.009) and better detection of severe hypokinetic disorders in 4% of patients, which were missed by MRS. CONCLUSIONS: MRS may uniquely identify abnormal motility/pressurization patterns, such as paradoxical LES response, distal pressurization, hypercontractile, and spasm patterns. These findings argue for a tailored approach when selecting provocative testing. MRS may be more useful for patients with abnormal pathophysiology, while AVS may help to supplement MRS in detecting severe hypokinetic disorders in preoperative management.

Preoperative physiological esophageal assessment for anti-reflux surgery: A guide for surgeons on high-resolution manometry and pH testing.

Gastroesophageal reflux disease (GERD) is one of the most commonly encountered digestive diseases in the world, with the prevalence continuing to increase. Many patients are successfully treated with lifestyle modifications and proton pump inhibitor therapy, but a subset of patients require more aggressive intervention for control of their symptoms. Surgical treatment with fundoplication is a viable option for patients with GERD, as it attempts to improve the integrity of the lower esophageal sphincter (LES). While surgery can be as effective as medical treatment, it can also be associated with side effects such as dysphagia, bloating, and abdominal pain. Therefore, a thorough pre-operative assessment is crucial to select appropriate surgical candidates. Newer technologies are becoming increasingly available to help clinicians identify patients with true LES dysfunction, such as pH-impedance studies and high-resolution manometry (HRM). Pre-operative evaluation should be aimed at confirming the diagnosis of GERD, ruling out any major motility disorders, and selecting appropriate surgical candidates. HRM and pH testing are key tests to consider for patients with GERD like symptoms, and the addition of provocative measures such as straight leg raises and multiple rapid swallows to HRM protocol can assess the presence of underlying hiatal hernias and to test a patient's peristaltic reserve prior to surgery.

Patterns of esophageal dysmotility elicited by multiple rapid swallows.

BACKGROUND: High-resolution manometry (HRM) is a gastrointestinal motility diagnostic system that measures intraluminal pressures using closely aligned sensors. Multiple rapid swallows (MRS) are used in conjunction with HRM to assess esophageal physiology prior to anti-reflux and hiatal hernia procedures. METHODS: A retrospective, qualitative study was conducted on 90 patients who underwent HRM with MRS in a single community clinic. 80 patients met the inclusion criteria. MRS testing consisted of rapid 2 mL swallows in 2-3 s intervals with patients in a seated, upright position. Clinical information was reviewed including indications for HRM, prior diagnostic workup, manometry, distal contractile integral (DCI), and integrated residual pressure (IRP). HRM studies were visualized using Manoview Analysis Software v3.0 (Medtronic). RESULTS: Certain esophageal dysmotility and pressurization manometry patterns were previously undetected on HRM alone. In our study, the addition of MRS was clinically helpful in (1) assessing contraction reserve, (2) highlighting features of jackhammer, (3) stimulating esophageal spasm, and (4) visualizing distal esophageal pressurization pattern with mechanical obstruction. Additionally, abnormal pathophysiology such as (5) paradoxical LES contraction (achalasia) and (6) loss of deglutition inhibition were identified. MRS had a diagnostic utility of 21.25% (n = 17) among the 80 patients. An intolerance rate of 7.7% (n = 7) was observed in patients unable to complete the protocol. CONCLUSIONS: Augmentation of HRM with MRS produces unique manometric features that have clinical utility in uncovering esophageal disorders. MRS provocation testing is a practical, inexpensive, well-tolerated addition to HRM that may yield useful clinical information to guide complicated diagnoses and medical management.
