Initial management and outcomes of nonmalignant esophageal perforations: A Nationwide Inpatient Sample analysis.

BACKGROUND: Management of esophageal perforation includes open surgery, minimally invasive surgery, and endoscopic stent placement. This study analyzed initial treatment and the associated short-term outcomes. METHODS: A retrospective study using the National Inpatient Sample between October 2015 and December 2019 identified adults >18 years with esophageal perforation undergoing an initial nonelective esophageal procedure categorized into either open surgery, minimally invasive surgery, or endoscopic stent placement. Patients with esophageal cancer were excluded. Baseline characteristics and the van Walraven-weighted Elixhauser Comorbidity Index were identified. Outcomes included in-hospital mortality and postintervention complications. Univariable and multivariable Cox regression was used to compare in-hospital survival. RESULTS: In total, 3,345 patients met inclusion criteria: the median age was 62 years (interquartile range 50-72 years), and 1,310 (39%) were female. Open procedure was pursued in 2,650 (79%), minimally invasive surgery in 310 (9%), and endoscopic stent placement in 385 (12%) with no differences in van Walraven-weighted Elixhauser Comorbidity Index or mortality. Patients who underwent minimally invasive surgery had a greater proportion of gastrointestinal complications (P = .006); otherwise, there were no differences in postintervention complications. In total, 380 (11%) patients died and were significantly older, with greater van Walraven-weighted Elixhauser Comorbidity Index, and had more postintervention complications. Univariable Cox regression identified age (hazard ratio 1.95, P < .001), van Walraven-weighted Elixhauser Comorbidity Index (hazard ratio 1.06, P < .001), stent placement (hazard ratio 1.93, P = .045), and transfer from a health facility (HR 2.40, P = .049) as associated with decreased in-hospital survival. Multivariable Cox regression revealed age (hazard ratio 1.041, P < .001) and van Walraven-weighted Elixhauser comorbidity index (hazard ratio 1.055, P < .001) were associated with decreased in-hospital survival. CONCLUSION: Patients with esophageal perforation had an 11% in-hospital mortality rate and significant associated complications regardless of intervention. Increasing age and comorbidities are associated with poorer in-hospital survival.

Active Observation as an Alternative to Invasive Treatments for Pediatric Head and Neck Lymphatic Malformations.

OBJECTIVES: An increasing number of treatment modalities for lymphatic malformations are being described, complicating therapeutic decisions. Understanding lymphatic malformation natural history is essential. We describe management of head and neck lymphatic malformations where decisions primarily addressed lesion-induced functional compromise (ie, breathing, swallowing) to identify factors associated with invasive treatment and active observation. We hypothesize that non-function threatening malformations can be observed. STUDY DESIGN: Retrospective case series. METHODS: Retrospective case series of consecutive head and neck lymphatic malformation patients (2000-2017) with over 2 years of follow-up. Patient characteristics were summarized and associations with invasive treatment (surgery or sclerotherapy) tested using Fisher's exact. In observed patients, factors associated with spontaneous regression were assessed with Fisher's exact test. RESULTS: Of 191 patients, 101 (53%) were male, 97 (51%) Caucasian, and 98 (51.3%) younger than 3 months. Malformations were de Serres I-III 167 (87%), or IV-V 24 (12%), and commonly located in the neck (101, 53%), or oral cavity (36, 19%). Initial treatments included observation (65, 34%) or invasive treatments such as primary surgery (80, 42%), staged surgery (25, 13%), or primary sclerotherapy (9, 5%). Of 65 initially observed malformations, 8 (12%) subsequently had invasive treatment, 36 (58%) had spontaneous regression, and 21 (32%) elected for no invasive therapy. Spontaneous regression was associated with location in the lateral neck (P = .003) and macrocystic malformations (P = .017). CONCLUSION: Head and neck lymphatic malformation treatment selection can be individualized after stratifying by stage, presence of functional compromise, and consideration of natural history. Recognizing the spectrum of severity is essential in evaluating efficacy of emerging treatments, as selected malformations may respond to observation.

Facial Nerve Branching Patterns Vary With Vascular Anomalies.

OBJECTIVES: At our institution, in vivo facial nerve mapping (FNM) is used during vascular anomaly (VAN) surgeries involving the facial nerve (FN) to create an FN map and prevent injury. During mapping, FN anatomy seemed to vary with VAN type. This study aimed to characterize FN branching patterns compared to published FN anatomy and VAN type. STUDY DESIGN: Retrospective study of surgically relevant facial nerve anatomy. METHODS: VAN patients (n = 67) with FN mapping between 2005 and 2018 were identified. Results included VAN type, FN relationship to VAN, FNM image with branch pattern, and surgical approach. A Fisher exact test compared FN relationships and surgical approach between VAN pathology, and FN branching types to published anatomical studies. MATLAB quantified FN branching with Euclidean distances and angles. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) analyzed quantitative FN patterns amongst VAN types. RESULTS: VANs included were hemangioma, venous malformation, lymphatic malformation, and arteriovenous malformation (n = 17, 13, 25, and 3, respectively). VAN FN patterns differed from described FN anatomy (P < .001). PCA and HCA in MATLAB-quantified FN branching demonstrated no patterns associated with VAN pathology (P = .80 and P = .91, one-way analysis of variance for principle component 1 (PC1) and priniciple component 2 (PC2), respectively). FN branches were usually adherent to hemangioma or venous malformation as compared to coursing through lymphatic malformation (both P = .01, Fisher exact). CONCLUSIONS: FN branching patterns identified through electrical stimulation differ from cadaveric dissection determined FN anatomy. This reflects the high sensitivity of neurophysiologic testing in detecting small distal FN branches. Elongated FN branches traveling through lymphatic malformation may be related to abnormal nerve patterning in these malformations. LEVEL OF EVIDENCE: NA Laryngoscope, 130:2708-2713, 2020.
