Facial microbial flora in bearded versus nonbearded men in the operating room setting: A single-center cross-sectional STROBE-compliant observational study.

Beards are controversial in the operating room setting because of the possible retention and shedding of pathogens. Surgical site infection poses a significant burden on healthcare systems. All male healthcare workers who entered the operating room were approached to participate in the study. Four facial swab samples were anonymously collected and a hygiene practice questionnaire was administered. Sample A was taken from the upper and lower lips, sample B from cheeks, and samples C and D were collected by 20 and 40 cm shedding below the face. Colony-forming units (CFUs) and minimum inhibitory concentrations (MICs) of meropenem resistance were determined for samples A and B. Random samples from A, B, C, and D, in addition to meropenem-resistant isolates were cultured with chlorohexidine. Sixty-one bearded and 19 nonbearded healthcare workers participated in the study. 98% were positive for bacterial growth with CFU ranging between 30 × 104 and 200 × 106 CFU/mL. Bacterial growth was significantly higher in bearded participants (P < .05). Eighteen (27.1%) isolates were resistant to meropenem; of these which 14 (77.8%) were from bearded participants, this was not statistically significant. Chlorohexidine was effective in inhibiting the growth of all strains including the meropenem-resistant isolates. Bearded men in the operating room had a significantly higher facial bacterial load. Larger-scale resistance studies are needed to address facial bacterial resistance among healthcare workers in the operating room. This study aimed to estimate the facial microbial load and identify strains and antimicrobial resistance profiles in bearded versus nonbearded male healthcare workers in the operating room of a tertiary hospital in the Middle East.

Comparing Emergent and Elective Colectomy Outcomes in Elderly Patients: A NSQIP Study.

INTRODUCTION: With the increasing prevalence of colorectal cancer (CRC) worldwide, especially in the elderly, and the variability between physiological and chronological age and its impact on functional status, acute symptoms leading to emergent surgery due to colorectal malignancy may lead to increased morbidity and mortality. The aim of this study is to identify the outcome differences of elective vs. emergent open colectomy in patients above 80 years. METHODS: The National Surgical Quality Improvement Program (NSQIP) database was reviewed from 2010 to 2014 for open colectomy based on CPT codes. Comparison between groups was done based on the clinical context at presentation as elective or emergent surgery. Data were analyzed using SAS. RESULTS: Elective colectomies were performed in 8289 (70.8%) vs. emergent colectomies in 3409 (29.1%). Emergent colectomy patients had higher American Society of Anesthesiologists (ASA) preoperative classification III-IV, 1429 (42.0%) and 224 (6.6%), vs. 1238 (14.9%) and 21 (0.2%) in elective colectomy patients (p < 0.0001). Emergent colectomy patients had more comorbidities such as chronic obstructive pulmonary disorder (493 (14.5%) vs. 796 (9.6%)), congestive heart failure (206 (6.0%) vs. 310 (3.8%)), dialysis (106 (3.1%) vs. 56 (0.7%)), and acute renal failure (166 (4.9%) vs. 46 (0.6%)) (p < 0.0001), respectively. Postoperative morbidity and mortality were significantly higher in emergent colectomy (1651 (48.4%) and 872 (25.6%)) vs. elective colectomy (1859 (22.4%) and 567 (6.8%)) (p < 0.0001), respectively. CONCLUSION: Emergent open colectomy in elderly patients carries a higher risk of morbidity and mortality when compared to elective open colectomy with risk factors being higher ASA classification and more comorbidities.

Predicting Conversion from Laparoscopic to Open Cholecystectomy: A Single Institution Retrospective Study.

BACKGROUND: Laparoscopic cholecystectomy (LC) is the standard surgical treatment for benign gallbladder disease. Nevertheless, conversion to open cholecystectomy (OC) is needed in some cases. The aim of this study is to calculate our institutional conversion rate and to identify the variables that are implicated in increasing the risk of conversion (LC-OC). MATERIALS AND METHODS: We carried out a retrospective study of all cases of LC performed at the American University of Beirut Medical Center between 2000 and 2015. Each (LC-OC) case was randomly matched to a laparoscopically completed case by the same consultant within the same year of practice, as the LC-OC case, in a 1:5 ratio. Forty-eight parameters were compared between the two study groups. RESULTS: Forty-eight out of 4668 LC were converted to OC over the 15-year study period; the conversion rate in our study was 1.03%. The variables that were found to be most predictive of conversion were male gender, advanced age, prior history of laparotomy, especially in the setting of prior gunshot wound, a history of restrictive or constrictive lung disease and anemia (Hb < 9 g/dl). The most common intraoperative reasons for conversion were perceived difficult anatomy or obscured view secondary to severe adhesions or significant inflammation. Patients who were in the LC-OC arm had a longer length of hospital stay. CONCLUSION: Advance age, male gender, significant comorbidities and history of prior laparotomies have a high risk of conversion. Patients with these risk factors should be counseled for the possibility of conversion to open surgery preoperatively. Further research is needed to determine whether these high risks patients should be operated on by surgeons with more extensive experience in minimal invasive surgery.
