    Preoperative pain measures ineffective in outpatient abdominal surgeries.
    Am J Surg 2018 Feb 6. Epub 2018 Feb 6.
    University of Denver, United States. Electronic address:
    Background: The multimodality addition of preoperative gabapentin, acetaminophen, and celecoxib (GAC) and postoperative TENS has been recommended to diminish narcotics. We predict that GAC-TENS implementation will reduce recovery room time, improve pain control, reduce narcotic refills, and demonstrate usefulness of TENS treatment.

    Methods: A prospective study compared a control group of patients not utilizing the GAC-TENS protocol during 2015 to patients using the GAC-TENS protocol during 2016. Read More

    The evolving role of pre-pectoral ADM-assisted implant-based immediate breast reconstruction following skin-sparing mastectomy.
    Am J Surg 2018 Feb 2. Epub 2018 Feb 2.
    The London Breast Institute, The Princess Grace Hospital, 42-52 Nottingham Place, London W1U 5NY, UK. Electronic address:
    Introduction: The increasing use of acellular dermal matrix (ADM) and fat transfer in the context of breast reconstruction, following skin sparing mastectomy (SSM) for therapeutic and risk reducing purposes, combined with the need to eliminate animation deformities, reduce post-operative dysfunctional pain and the risk of capsular contracture, has prompted surgeons to investigate the possibility of placing the mammary implant over the pectoralis major muscle with complete coverage with ADM thus reviving the pre-pectoral approach which was previously abandoned due to high complications rates and poor aesthetics in the pre-ADM era.

    Methods: We reviewed the literature regarding this evolving technique of muscle sparing ADM-assisted implant-based immediate breast reconstruction.

    Results And Conclusions: Several authors have recently reported positive early results confirming the potential benefits of eliminating breast animation and reducing postoperative pain, however, most of these reports contain insufficient numbers of patients (<100) and were retrospective in nature with a very short-term follow-up and lack of data regarding objective aesthetic assessment.

    Department of Surgery, The Ohio State University, Wexner Medical Center, Columbus, OH, USA. Electronic address:
    Background: Shared decision-making (SDM) is a process that respects the rights of patients to be fully involved in decisions about their care. By evaluating all available healthcare options and weighing patients' personal values and preferences against available unbiased evidence, patients and healthcare professionals can make health-related decisions together, as partners. We sought to evaluate the impact of perceived SDM on patient-reported outcomes, healthcare quality, and healthcare utilization. Read More
