Laparoscopic Heller Myotomy With EGD and Balloon Dilation: A Durable Solution for Achalasia.

BACKGROUND: Laparoscopic Heller myotomy (LHM) and esophageal balloon dilation (BD) are the two mainstays of achalasia treatment-this study examines the outcomes when they are performed simultaneously without fundoplication. METHODS: All patients undergoing LHM&BD were reviewed for demographic and procedural data, and to see if additional procedures for achalasia had been performed. Patients were surveyed using the Eckardt score and the GERD quality-of-life score (GERD-HRQL) to assess the durability of repair. RESULTS: From 2013-2020, 66 patients underwent LHM&BD. There were no esophageal perforations and a median LOS of 1 day. Seven patients have required additional operations or procedures at median 4-years follow up. 31 patients (47%) responded to the survey. The average Eckardt score was 2.9 (goal<4) with mean GERD-HRQL of 14.4 (goal<25). CONCLUSIONS: LHM&BD allows for a safe, durable repair of achalasia. Reflux symptoms are manageable with PPI without fundoplication and the re-intervention rate similar to published values.

Contamination of hybrid hernia meshes compared to bioresorbable Phasix™ Mesh in a rabbit subcutaneous implant inoculation model.

BACKGROUND: Hybrid hernia meshes combine biological tissue-derived extracellular matrix with permanent or resorbable synthetic. The objective of this study was to evaluate hybrid meshes (Gore® Synecor, Zenapro™, Ovitex™ 1S Reinforced Bioscaffold Permanent, and Ovitex™ 1S Reinforced Bioscaffold Resorbable) compared to non-hybrid, bioresorbable synthetic mesh (Phasix™ Mesh) in a rabbit bacterial inoculation model. MATERIALS AND METHODS: Subcutaneous pockets were bilaterally created in male, New Zealand White rabbits (n = 25). Circular meshes (3.8 cm diameter) were implanted and inoculated with 1 × 106 colony forming units (CFU) of clinically-isolated methicillin-resistant Staphylococcus aureus (MRSA). A given animal received a single mesh type. Seven days post-inoculation, animals were euthanized and white material and microbial colonization were assessed by abscess scoring and CFU quantification, respectively. Non-parametric Kruskal-Wallis with Dunn's post-hoc tests compared results for different meshes. RESULTS: Phasix™ Mesh and Synecor exhibited significantly lower abscess scores than Zenapro™, Ovitex™ 1S Permanent, and Ovitex™ 1S Resorbable (p < 0.05). All pocket swabs for Zenapro™ and Ovitex™ meshes were positive for MRSA (100%), with 20% of Synecor and 0% Phasix™ Mesh. Microbial colonization was significantly lower for Phasix™ Mesh (0 CFU) relative to Zenapro™ (6.73 × 107 CFU (median)), Ovitex™ 1S Permanent (7.87 × 107 CFU) and Ovitex™ 1S Resorbable (1.45 × 108 CFU), and for Synecor (0 CFU) relative to both Ovitex™ meshes. Phasix™ Mesh was the only device with no detectable abscess or microbial colonization. CONCLUSION: Phasix™ Mesh demonstrated no detectable abscess or microbial colonization at 7-days post-implantation and inoculation, in contrast with four hybrid meshes, which all demonstrated colonization in a rabbit bacterial inoculation model.

Fibrin Sealant: A Review of the History, Biomechanics, and Current Applications for Prosthetic Fixation in Hernia Repair.

The role of surgical adhesives in hernia repair has continued to evolve. The purpose of this chapter is to review the role of fibrin sealant and its application in general surgery for mesh fixation, specifically the history, biomechanics, and clinical utilization. The utilization of fibrin sealant for repair of groin hernias, both open and laparoscopic, ventral hernias, and hiatal hernias will be discussed.

The effect of endoscopic sinus surgery on symptoms of eustachian tube dysfunction.

BACKGROUND: The symptom of eustachian tube dysfunction has been categorized as a "minor" symptom in chronic rhinosinusitis. The aim of this pilot study was to determine the frequency of otologic symptoms in patients with confirmed rhinosinusitis and the likelihood of its resolution in those patients undergoing endoscopic sinus surgery (ESS). METHODS: Questionnaires were obtained from 168 patients who had undergone prior ESS over a 5-year period. Patients were asked to evaluate if they suffered from several different potential symptoms of eustachian tube dysfunction before ESS and whether that symptom changed postoperatively. RESULTS: Using the binomial test, 95% confidence intervals were determined for the following otologic symptoms of tubal dysfunction: "earfullness and congestion," "ear cracking and popping," "dizziness," and "ear pain. "ESS was found to have a significant treatment effect for the indicated otologic symptoms of tubal dysfunction. CONCLUSION: Tubal dysfunction, as manifested by otologic symptoms, is common in patients with chronic rhinosinusitis undergoing ESS. The classification of this as a "minor" symptom of rhinosinusitis needs to be reevaluated. These symptoms improve or resolve in the majority of patients undergoing ESS.
