OBJECTIVE: The aim of this study was to compare weight loss, obesity-related comorbidities, and biochemical outcomes of LSG versus LRYGB through a meta-analysis of randomized controlled trials (RCTs). SUMMARY OF BACKGROUND DATA: LSG and LRYGB are the 2 most commonly performed bariatric surgeries for the treatment of obesity. The comparative outcomes of the 2 surgeries is a topic of ongoing debate and medium-term outcomes remain uncertain. METHODS: A search for RCTs comparing LRYGB versus LSG was conducted...

OBJECTIVE: To understand and overcome the challenges associated with moving life-urgent payloads using unmanned aircraft. BACKGROUND DATA: Organ transportation has not been substantially innovated in the last 60 years. Unmanned aircraft systems (UAS; ie, drones) have the potential to reduce system inefficiencies and improve access to transplantation. We sought to determine if UASs could successfully be integrated into the current system of organ delivery. METHODS: A multi-disciplinary team was convened to design and build an unmanned aircraft to autonomously carry a human organ...

OBJECTIVE: This study aimed to conduct a genomewide transcriptomic profiling to develop a microRNA (miRNA)-based signature for the identification of peritoneal metastasis (PM) in patients with gastric cancer (GC). SUMMARY BACKGROUND DATA: Even though PM in patients with GC has long been recognized to associate with poor prognosis, currently there is lack of availability of molecular biomarkers for its robust diagnosis. METHODS: We performed a systematic biomarker discovery by analyzing miRNA expression profiles in primary tumors from GC patients with and without PM, and subsequently validated the expression of candidate miRNA biomarkers in 3 independent clinical cohorts of 354 patients with advanced GC...

BACKGROUNDS: To determine the potential survival benefit associated with robotic-assisted laparoscopic prostatectomy (RALP) compared to open radical prostatectomy (ORP) for prostate cancer. SUMMARY OF BACKGROUND DATA: RALP has become the dominant surgical approach for localized disease in the absence of randomized clinical evidence and despite of the factor that RALP is more expensive than ORP. METHODS: We performed a cohort study involving patients who underwent RALP and ORP for localized prostate cancer at the Commission on Cancer-accredited hospitals in the United States...

OBJECTIVE: To test the hypothesis that surgical site infection (SSI) risk differs, after administration of surgical antibiotic prophylaxis (SAP) within 60-30 or 30-0 minutes before incision. BACKGROUND: The importance of appropriate timing of SAP before surgery has long been recognized. However, available evidence is contradictive on the best timing within a 60-0 minutes time interval before incision. Here, we aim to evaluate previous contradictions with a carefully designed observational cohort...

OBJECTIVE: The aim of this study was to determine characteristics of the most cited publications in the history of the American Surgical Association (ASA). SUMMARY BACKGROUND DATA: The Annals of Surgery has served as the journal of record for the ASA since 1928, with a special issue each year dedicated to papers presented before the ASA Annual Meeting. METHODS: The top 100 most cited ASA publications in the Annals of Surgery were identified from the Scopus database and evaluated for key characteristics...

OBJECTIVE: Our aims were to assess North American trends in the management of patients undergoing pancreatoduodenectomy (PD) and distal pancreatectomy (DP), and to quantify the delivery of optimal pancreatic surgery. BACKGROUND: Morbidity after pancreatectomy remains unacceptably high. Recent literature suggests that composite measures may more accurately define surgical quality. METHODS: The 2013 to 2017 American College of Surgeons National Surgical Quality Improvement Program Participant Use Files were queried to identify patients undergoing PD (N = 16,222) and DP (N = 7946)...

OBJECTIVE: To measure the association between patient-reported satisfaction and regret and clinical outcomes. SUMMARY OF BACKGROUND DATA: Patient-reported outcomes are becoming an increasingly important marker of the quality of patient care. It is unclear however, how well patient-reported outcomes adequately reflect care quality and clinical outcomes in surgical patients. METHODS: Retrospective, population-based analysis of adults ages 18 and older undergoing surgery across 38 hospitals in Michigan between January 1, 2017 and May 31, 2018...

OBJECTIVE: Compare oncologic outcomes after open and robotic pancreatic resections for pancreatic adenocarcinoma (PDAC). SUMMARY OF BACKGROUND DATA: Receipt of adjuvant chemotherapy improves survival after resected PDAC. Complications after pancreatectomy have been shown to prohibit the administration of adjuvant chemotherapy and survival. We examined the effect of surgical approach on receipt of adjuvant chemotherapy, complications, and overall survival after pancreatectomy...

OBJECTIVE: We sought to describe contemporary presentation, treatment, and outcomes of patients presenting with acute (A), perforated (P), and gangrenous (G) appendicitis in the United States. SUMMARY BACKGROUND DATA: Recent European trials have reported that medical (antibiotics only) treatment of acute appendicitis is an acceptable alternative to surgical appendectomy. However, the type of operation (open appendectomy) and average duration of stay are not consistent with current American practice and therefore their conclusions do not apply to modern American surgeons...

OBJECTIVE: To describe and critique tools used to assess frailty in vascular surgery patients, and investigate its associations with patient factors and outcomes. BACKGROUND: Increasing evidence shows negative impacts of frailty on outcomes in surgical patients, but little investigation of its associations with patient factors has been undertaken. METHODS: Systematic review and meta-analysis of studies reporting frailty in vascular surgery patients (PROSPERO registration: CRD42018116253) searching Medline, Embase, CINAHL, PsycINFO, and Scopus...

OBJECTIVE: The aim of this study was to identify the effects of recent innovations in trauma major hemorrhage management on outcome and transfusion practice, and to determine the contemporary timings and patterns of death. BACKGROUND: The last 10 years have seen a research-led change in hemorrhage management to damage control resuscitation (DCR), focused on the prevention and treatment of trauma-induced coagulopathy. METHODS: A 10-year retrospective analysis of prospectively collected data of trauma patients who activated the Major Trauma Centre's major hemorrhage protocol (MHP) and received at least 1 unit of red blood cell transfusions (RBC)...

OBJECTIVE: To assess the comparative risk of recurrence and ostomy after elective resection or medical therapy for uncomplicated diverticulitis, incorporating outpatient episodes of recurrence. BACKGROUND: While surgeons historically recommended colon resection for uncomplicated diverticulitis to reduce the risk of recurrence or colostomy, no prior studies have quantified this risk when considering outpatient episodes of disease. It remains to be determined whether surgery actually decreases those risks...

OBJECTIVE: We aimed to describe our experience and the learning curve of 450 cases of robot-assisted pancreaticoduodenectomy (RPD) and optimize the surgical process so that our findings can be useful for surgeons starting to perform RPD. SUMMARY BACKGROUND DATA: Robotic surgical systems were first introduced 20 years ago. Pancreaticoduodenectomy (PD) is a challenging surgery because of its technical difficulty. RPD may overcome some of these difficulties. METHODS: The medical records of 450 patients who underwent RPD between May 2010 and December 2018 at the Shanghai Ruijin Hospital were retrospectively analyzed...
