Early Successful Experiences of Surgical Conversion of Endoscopic Gastric Plication to Roux-en-Y Gastric Bypass.

The primary obesity surgery endoluminal (POSE) procedure is an innovative incision-less endoscopic bariatric procedure that is increasingly used. However, variable weight loss response and recurrence post-endoscopic bariatric procedures have at times necessitated laparoscopic bariatric conversion. The safety and approach of conversion to laparoscopic sleeve gastrectomy (LSG) or Roux-en-Y gastric bypass (RYGB), however, have been an active point of discussion within revisional bariatric surgery. This retrospective review of four consecutive patients is the largest description of medium-term postoperative outcomes and technical highlights of a laparoscopic conversion of POSE to RYGB. Chart review was completed to evaluate patients' post-POSE clinical course and perioperative outcomes after surgical conversion. Early data suggests varied weight loss trajectory with POSE and marked improvement in weight response after surgical conversion. Qualitative review reveals successful single-staged conversions contrary to previous smaller case series describing staged conversions involving endoscopic removal of plications followed by RYGB. Review additionally reveals key perioperative considerations for successful conversions to include intraoperative endoscopy, upper gastrointestinal fluoroscopic studies, and at times computed tomography. The latter study and laparoscopic view of the post-POSE stomach challenge the prior notion that distal POSE allows for easy revision to LSG. Our case series underscores the complex multifactorial nature of metabolic disease and the increasing importance of a conscientious approach to conversion bariatric surgery as the adoption of POSE and the bariatric patient population continues to grow.

Incorporating Microdebrider Use in a Community-Based Thyroidectomy Practice.

Objectives: Substernal goiters often require surgery, yet their location presents challenges. Most can be removed via transcervical approach, but extent and relationship to mediastinal structures can merit consideration of sternotomy and assistance of colleagues. Despite widespread use in sinus surgery and previous literature reports, microdebrider use to facilitate transcervical removal of substernal goiters has not been broadly adopted. Our objective was to report our experience with use of the soft tissue shaver to facilitate substernal goiter deliver through a cervical incision in a community-based thyroidectomy practice. Methods: We reviewed thyroidectomy cases performed by a general otolaryngologist (D.M.Y.) in a community setting from January 2017 through December 2019. Four patients required microdebrider use for intracapsular debulking of substernal goiter to allow for transcervical removal. We discuss pre- and perioperative considerations, present computed tomography (CT) and operative images, review surgical technique, and report estimated blood loss (EBL), surgical time (T), complications, and length of stay. Results: Average EBL was 237.5 ml (range 100-500 ml). Average T was 137 minutes (range 121-170 minutes). No patients required sternotomy. One patient developed postoperative hematoma requiring evacuation and cautery of a bleeding site. No other complications were encountered, all patients were discharged after overnight observation. Conclusions: The microdebrider can be safely utilized by general otolaryngologists to facilitate transcervical removal of substernal goiters. Adoption of this familiar tool for a different surgical application can reduce the need for sternotomy, assistance of colleagues, or referral to a tertiary care center, with associated decrease in risk, morbidity, surgical time, length of stay, and cost, and improved patient convenience and satisfaction.

Wound-Healing Effects of Common Antineoplastic Agents and Perioperative Considerations for the Orthopaedic Surgeon.

In oncologic patients, optimal postoperative wound healing is crucial for the maintenance of systemic therapies and improved survival. Although several risk factors for postoperative wound complications have been identified, the clinical effect of new antineoplastic agents on wound healing remains uncertain. The available literature on the effect of antineoplastic agents in wound healing is complex to analyze because of other confounding risk factors such as radiation therapy and certain patient-specific variables. Available perioperative drug recommendations are based on database opinion and case reports from adverse event alerts. This review highlights the characteristics of old and new antineoplastic agents commonly used in the treatment of sarcoma, carcinoma, and other cancers and their potential effects on the wound-healing process. It also aims to provide perioperative treatment cessation recommendations to guide orthopaedic surgeons and prevent drug-related wound complications to the fullest extent possible.

Glucagon-Like Peptide-1 Agonists and General Anesthesia: Perioperative Considerations and the Utility of Gastric Ultrasound.

Glucagon-like peptide-1 (GLP-1) agonists are very popular and useful medications for the treatment of type 2 diabetes mellitus and obesity. Potent gastric emptying delay is common with these medications, serving as a major contributor to the postprandial glycemic control and weight loss benefits of these medications. Recently, multiple case reports and studies indicating safety risks for these medications and their use in patients planning to undergo general anesthesia have been published, as retained gastric contents can lead to intraoperative aspiration. New guidelines for these medications have been released to guide clinical practice for anesthesiologists. Some degree of preoperative cessation of these medications is required. At this time, the ideal window for cessation of these medications to optimize clinical efficacy while reducing aspiration risks has not yet been well elaborated on. Aspiration of gastric contents can still occur despite appropriate preoperative fasting in patients taking GLP-1 agonists. Gastric ultrasound appears to be an effective and objective way of preoperatively assessing a patient's stomach contents to make decisions regarding anesthetic management for patients prescribed these medications. This practice is limited by a general lack of training and implementation in current anesthesiology practice.

Perioperative Considerations in Patients with Vein of Galen Malformation Undergoing Embolization–A Single-Institution Case Series

AbstractVein of Galen malformation (VOGM) is a congenital, intracranial vascular malformation, with an extracardiac shunt. Neonates can present with high output cardiac failure, pulmonary hypertension, or multiorgan failure and are at high risk of perioperative complications, especially in remote locations. We conducted a retrospective single-center analysis of the perioperative management of patients with VOGM presenting for embolization. Patients were identified by querying both the hospital billing dataset using International Classification of Diseases-10 diagnosis or billing code and the Neuro-interventional Radiology Database, from January 2011 to March 2020. As many as 14 patients were identified, 12 of which underwent definitive treatment. Six patients who underwent embolization in the neonatal period had pulmonary hypertension. Those children required varying degrees of hemodynamic and respiratory support preoperatively and experienced significant intraoperative events, including one intraoperative cardiac arrest. Caring for these critically ill patients in a remote location requires proper planning to prevent adverse outcomes.

Consensus Statements among European Sleep Surgery Experts on Snoring and Obstructive Sleep Apnea: Part 2 Decision-Making in Surgical Management and Peri-Operative Considerations.

Background: Reaching consensus on decision-making in surgical management and peri-operative considerations regarding snoring and obstructive sleep apnea (OSA) among sleep surgeons is critical in the management of patients with such conditions, where there is a large degree of variability. Methods: A set of statements was developed based on the literature and circulated among eight panel members of European experts, utilizing the Delphi method. Responses were provided as agree and disagree on each statement, and the comments were used to assess the level of consensus and develop a revised version. The new version, with the level of consensus and anonymized comments, was sent to each panel member as the second round. This was repeated for a total of five rounds. Results: The final set included a total of 71 statements: 29 stand-alone and 11 with 42 sub-statements. On the 33 statements regarding decision-making in surgical management, there was 60.6%, 27.3%, and 6.1% consensus among all eight, seven, and six panelists, respectively. On the 38 statements regarding the peri-operative considerations, there was 55.3%, 18.4%, and 15.8% consensus among all eight, seven, and six panelists, respectively. Conclusions: These results indicate the need for an expanded review of the literature and discussion to enhance consensus among the sleep surgeons that consider surgical management in patients with snoring and OSA.

Perioperative Considerations for Use of Custom Metallic Implants in Limb Reconstruction.

The surgical management of critical bone defects remains challenging. Regardless of whether bone loss is acute or the result of staged surgical resection, current surgical management often requires advanced reconstructive techniques, many of which require multiple surgical procedures and consistent patient involvement with applied internal or external orthopaedic devices. The utilization of three-dimensional (3D) printing technology has continued to expand across orthopaedic subspecialties; in orthopaedic trauma, custom metallic implants are being used in the management of critical bone defects. Implementation of this technique may be advantageous in certain clinical situations. The perioperative considerations for placement of a custom bone defect printed metallic implant are presented in conjunction with demonstrative clinical cases.

Perioperative Considerations in Older Kidney and Liver Transplant Recipients: A Review.

With the growth of the older adult population, the number of older adults waitlisted for and undergoing kidney and liver transplantation has increased. Transplantation is an important and definitive treatment for this population. We present a contemporary review of the unique preoperative, intraoperative, and postoperative issues that patients older than 65 y face when they undergo kidney or liver transplantation. We focus on geriatric syndromes that are common in older patients listed for kidney or liver transplantation including frailty, sarcopenia, and cognitive dysfunction; discuss important considerations for older transplant recipients, which may impact preoperative risk stratification; and describe unique challenges in intraoperative and postoperative management for older patients. Intraoperative challenges in the older adult include using evidence-based best anesthetic practices, maintaining adequate perfusion pressure, and using minimally invasive surgical techniques. Postoperative concerns include controlling acute postoperative pain; preventing cardiovascular complications and delirium; optimizing immunosuppression; preventing perioperative kidney injury; and avoiding nephrotoxicity and rehabilitation. Future studies are needed throughout the perioperative period to identify interventions that will improve patients' preoperative physiologic status, prevent postoperative medical complications, and improve medical and patient-centered outcomes in this vulnerable patient population.

Perioperative Considerations for the Surgical Treatment of Crohn's Disease with Discussion on Surgical Antibiotics Practices and Impact on the Gut Microbiome.

Crohn's disease, a chronic inflammatory process of the gastrointestinal tract defined by flares and periods of remission, is increasing in incidence. Despite advances in multimodal medical therapy, disease progression often necessitates multiple operations with high morbidity. The inability to treat Crohn's disease successfully is likely in part because the etiopathogenesis is not completely understood; however, recent research suggests the gut microbiome plays a critical role. How traditional perioperative management, including bowel preparation and preoperative antibiotics, further changes the microbiome and affects outcomes is not well described, especially in Crohn's patients, who are unique given their immunosuppression and baseline dysbiosis. This paper aims to outline current knowledge regarding perioperative management of Crohn's disease, the evolving role of gut dysbiosis, and how the microbiome can guide perioperative considerations with special attention to perioperative antibiotics as well as treatment of Mycobacterium avium subspecies paratuberculosis. In conclusion, dysbiosis is common in Crohn's patients and may be exacerbated by malnutrition, steroids, narcotic use, diarrhea, and perioperative antibiotics. Dysbiosis is also a major risk factor for anastomotic leak, and special consideration should be given to limiting factors that further perturb the gut microbiota in the perioperative period.

Surgical management of pediatric Crohn's disease

Management of pediatric-onset Crohn's disease uniquely necessitates consideration of growth, pubertal development, psychosocial function and an increased risk for multiple future surgical interventions. Both medical and surgical management are rapidly advancing; therefore, it is increasingly important to define the role of surgery and the breadth of surgical options available for this complex patient population. Particularly, the introduction of biologics has altered the disease course; however, the ultimate need for surgical intervention has remained unchanged. This review defines and evaluates the surgical techniques available for management of the most common phenotypes of pediatric-onset Crohn's disease as well as identifies critical perioperative considerations for optimizing post-surgical outcomes.

Perioperative considerations for robotic-assisted thoracic surgery.

Robotic-assisted thoracic surgery is being offered to more patients because it has a number of potential benefits. Awareness of the challenges that this type of surgery brings will allow teams to manage these patients safely in the perioperative period.

Ambulatory total hip and knee arthroplasty: a literature review and perioperative considerations.

Total joint arthroplasty (TJA), particularly for the hip and knee, is one of the most commonly performed surgical procedures. The advancement/evolution of surgical and anesthesia techniques have allowed TJA to be performed on an ambulatory/same-day discharge basis. In this Continuing Professional Development module, we synthesize the perioperative evidence that may aid the development of successful ambulatory TJA pathways. We searched MEDLINE, Embase, CENTRAL, and the Cochrane Database of Systematic Reviews for ambulatory or fast-track TJA articles. In the absence of direct evidence for the ambulatory setting, we extrapolated the evidence from the in-patient TJA literature. Patient selection encompassing patient, medical, and social factors is fundamental for successful same-day discharge of patients following TJA. Evidence for the type of intraoperative anesthesia favours neuraxial technique for achieving same day discharge criteria and reduced perioperative complications. Availability of short-acting local anesthetic for neuraxial anesthesia would affect the anesthetic choice. Nonetheless, modern general anesthesia with multimodal analgesia and antithrombotics in a well selected population can be considered. Regional analgesia forms an integral part of the multimodal analgesia regime to reduce opioid consumption and facilitate same-day hospital discharge, reducing hospital readmission. For ambulatory total knee arthroplasty, a combination of adductor canal block with local anesthetic periarticular infiltration provided is a suitable regional analgesic regimen. Anesthesia for TJA has evolved as such that same-day discharge will become the norm for selected patients. It is essential to establish pathways for early discharge to prevent adverse effects and readmission in this population. As more data are generated from an increased volume of ambulatory TJA, more robust evidence will emerge for the ideal anesthetic components to optimize outcomes.

Perioperative Considerations in Management of the Severely Bleeding Coagulopathic Patient

(Anesthesiology. 2023; 138:535–560) This clinical review explored coagulopathy in severely bleeding patients after major surgery (eg, cardiac surgery with cardiopulmonary bypass or CPB), serious trauma, and postpartum hemorrhage. There are a multitude of surgical and nonsurgical factors, or a mix of both, that can cause perioperative bleeding in patients. This includes fibrinolysis, metabolic acidosis, platelet impairment, thrombocytopenia, coagulation factor deficiency, activation of inflammatory pathways, hemodilution, hypothermia, and hypovolemia. Bleeding patients can often have previous hemostatic issues because of oral anticoagulants or antiplatelet therapy.

Perioperative Considerations in Alpha-Gal Syndrome: A Review.

Galactose-⍺-1, 3-galactose (alpha-gal) is an oligosaccharide found in mammalian tissues that causes allergic reactions in patients with alpha-gal syndrome (AGS). AGS is a hypersensitivity reaction notable for both immediate and delayed allergic and anaphylactic symptoms. As a tick-based disease, AGS has gained increasing prevalence across the United States and can have a significant influence on which medications are safe for patients. Many medications used within the operating room and intensive care units have inactive ingredients that can be mammalian-derived and therefore should be vetted before administering to patients with AGS. Management of patients with AGS involves diligent action in the preoperative and perioperative settings to reduce patient exposure to potentially harmful medications. In conducting a comprehensive risk stratification assessment, the anesthesia team should identify any at-risk patients and determine which medications they have safely tolerated in the past. Despite obtaining a complete history, not all patients with AGS will be identified preoperatively. The perioperative team should understand which common medications pose a risk of containing alpha-gal moieties (e.g., heparins, gelatin capsules, vaccines, lidocaine patches, surgifoam, etc.​​). For this reason, this paper includes a compendium of common anesthetic medications that have been cross-referenced for ingredients that have the potential to cause an AGS reaction. Any potentially unsafe medications have been identified such that medical providers can cross-reference with the ingredients listed at their respective institutions.

Perioperative Considerations for Modern Leadless Pacemakers.

Since their initial approval by the Food and Drug Administration in 2016, leadless pacemakers have become increasingly prevalent. This growth has been driven by an improved adverse effect profile when compared to traditional pacemakers, including lower rates of infection, as well as eliminated risk of pocket hematoma and lead complications. More recently, technology enabling leadless synchronized atrioventricular pacing in patients with atrioventricular block has vastly expanded the indications for these devices. Anesthesiologists will increasingly be relied upon to safely care for patients with leadless pacemakers undergoing non-electrophysiology procedures and surgery. This article provides an overview of the technology, evidence base, current indications, and unique perioperative considerations for leadless pacemakers.
