Nationwide Analysis of Hospital Admissions Prior to Hartmann's Procedure for Acute Diverticulitis.

INTRODUCTION: Diverticular disease is one of the most common gastrointestinal diseases that require hospital admission. This study aims to identify trends in prior hospital admissions for patients that ultimately require a Hartmann's procedure for complicated diverticulitis. METHODS: The Nationwide Readmissions Database for 2010-2014 was queried for all patients aged 18 years or older admitted with an ICD-9 code for colonic diverticulitis and end colostomy creation. Patients with prior hospital admissions were identified. The primary outcome was mortality after Hartmann's procedure. Secondary outcomes were prior hospital admission and previous percutaneous drain placement. Multivariable logistic regression was performed to control for confounding factors for each outcome and results were weighted for national estimates. RESULTS: There were 90,162 patients admitted with complicated diverticulitis requiring end colostomy creation. Prior hospital admissions were found in 28.1% (n = 25,307) and 14.4% (n = 12,947) had a previous percutaneous drain placed during a prior admission. The overall mortality rate was 5.9% (n = 5314) after Hartman's procedure. The mortality rate for patients with prior hospital admissions was 8.7% (P < .001), and the mortality rate for patients with previous percutaneous drain placement was 4.3% (P < .001). After controlling for confounding factors including comorbidities, patients with prior admission had an increased risk of mortality (OR 1.48 [1.40-1.58], P < .001) and patients with previous percutaneous drain placement had a decreased risk of mortality (OR .66 [.60-.72], P < .001). CONCLUSIONS: Hospitalizations for complications of diverticulitis are a costly burden to our healthcare system. By identifying those patients at high risk for readmission and emergency surgery, perioperative outcomes may be improved.

Under the Microscope: The Evolution of Surgical Loupes.

Fine motor movements of the surgeon's hands are limited by the resolution of the eye. Surgical loupes have allowed the profession of surgery to surpass this threshold. This is a review of the historical milestones that lead up to the development of the modern-day loupes. We explore the Greco-Roman history of the magnifying lens, its subsequent application to corrective eyewear centuries later, and the multiple ground-breaking advancements of the compound lens microscope. Moreover, we review the development of pre-modern loupes as each iteration improved through time. The aim of this historical review is to kindle an appreciation for the millennia of development that led to such instrumental modern-day technology.

The Evolution of Bariatric Surgery-From Sewing Lips to Constructing the Sleeve.

Bariatric surgery remains the most durable weight loss option to address morbid obesity, providing lasting reduction of debilitating chronic comorbidities. This is a review of the historical milestones that led up to the development of this surgical practice. We explore perceptions and interventions for obesity as early as the 10th century, as well as pre-modern surgical perceptions and advancements in foregut and obesity surgery. Additionally, we recount select social and surgical landmarks in the modern bariatric era. The aim of this review is to reflect on and appreciate the centuries of progress that have led to such an instrumental branch of risk reductive surgery.

Student Perspectives on Implementing Stop the Bleed Training into Medical School Curriculum.

BACKGROUND: Following the Hartford Consensus guidelines and recommendations, third-year medical students from a single institution were offered an optional Stop the Bleed (STB) training course in August 2018. The aim of this study was to assess medical students' confidence in performing bleeding control techniques and teaching others after completing the STB course. The secondary goal was to assess student perception on integrating mandatory STB training into the medical school curriculum. MATERIALS AND METHODS: A 24-question survey using a 4-point Likert scale was administered to all medical students who completed STB training. Students were anonymously asked to self-report their confidence in performing bleeding control techniques, training others after STB training, and their perception on integrating STB training into medical school curriculum. RESULTS: After completing the STB course, 95% of students were comfortable applying a tourniquet, 92% of students were confident in packing wounds, and 99% of students could apply direct pressure to wounds to stop bleeding. Overall, 94% of students reported that STB training would be helpful for their clinical rotations. CONCLUSION: These results demonstrate that medical students are positively impacted by Stop the Bleed courses and validate that the implementation of mandatory STB courses into medical school curriculum will improve medical students' knowledge and skills for hemorrhage control.

Bile Leak following Laparoscopic Cholecystectomy due to Perforated Duodenal Ulcer in Patient with Roux-en-Y Gastric Bypass.

Perforated ulcers of the excluded stomach or duodenum are exceedingly rare in patients who have undergone Roux-en-Y gastric bypass surgery. The diagnosis of perforated ulcer after Roux-en-Y gastric bypass remains challenging as there is often absence of free air or contrast extravasation from the biliopancreatic limb. We present a patient with signs and symptoms of acute cholecystitis. Laparoscopic cholecystectomy was complicated by postoperative bile leak. EDGE procedure was performed to access the remnant stomach and endoscopic evaluation revealed a perforated ulcer in the posterior duodenal bulb. Although unusual, in patients with bariatric surgery and upper abdominal pain, differential diagnosis including perforated ulcer of the biliopancreatic limb must be considered and early surgical exploration is essential.

Clinical use of high mobility group box 1 and the receptor for advanced glycation end products in the prognosis and risk stratification of heart failure: a literature review.

Heart failure (HF) is a clinical syndrome that represents the end stage of heart disease and remains the leading cause of morbidity and mortality worldwide. As heart failure mortality rates remain elevated, additional biomarkers that facilitate early detection or risk stratification in HF is of particularly great interest. High mobility group box 1 (HMGB1) and receptor for advanced glycation end products (RAGE) cause the activation of intracellular signaling, gene expression, and production of inflammatory cytokines and have been linked to many inflammatory disease states such as diabetes mellitus and atherosclerosis. Few studies have investigated their role in the pathophysiology of HF and any significant correlation remains uncertain. Review of the available literature discussing HMGB1 and RAGE clinical values as independent prognostic variables in HF resulted in the inclusion of 11 studies, which enrolled a total of 2025 heart failure patients. Overall, the data suggests a statistically significant positive correlation between RAGE and HF, with increasing RAGE levels associated with increasing New York Heart Association (NYHA) functional class of heart failure. HMGB1 correlations were not as extensively studied, but there is evidence that both HMGB1 and RAGE have a definite potential as biomarkers for the prognosis and risk stratification of HF patients.
