Acute post-operative rhinosinusitis following endonasal dacryocystorhinostomy.

ABSTRACT: PURPOSE: To investigate the incidence and risk factors for acute rhinosinusitis (ARS) following endoscopic dacryocystorhinostomy (EnDCR). METHODS: Retrospective single-surgeon interventional case series, including 196 consecutive patients undergoing 203 endonasal DCR, with clinical and radiological evidence of nasolacrimal duct or common canalicular obstruction. Pre-operative lacrimal and sinonasal clinical assessment and imaging, intraoperative endoscopic video recording, and post-operative clinical and endoscopic findings were analysed for cases of ARS occurring within the first 4 weeks following DCR among patients with and without a past history of chronic rhinosinusitis (CRS). Surgical complications and outcomes at 12 months and management of ARS are reported. RESULTS: Three patients (1.5%) developed ARS within the first 5 post-operative days, none of which had experienced peri-operative complications and all had a past history of CRS. The rate of CRS in this cohort of 196 patients was 10.2% (n=20), of which 15% (n=3) developed ARS, although none had symptoms of CRS at the time of surgery; one had undergone previous sinus surgery. Presenting symptoms of ARS included facial pain, tenderness over the affected sinus, and nasal discharge; all patients responded to oral antibiotic therapy. DISCUSSION: The rate of ARS following EnDCR was 1.5%. In those with a prior history of CRS, it was 15% (P=0.009). ARS developed within the first post-operative week among patients with a past history of CRS, who were asymptomatic at the time of surgery, and responded to oral antibiotics. CRS may be a risk factor for the development of post-operative ARS.

Project description:BackgroundEpiphora is a common complaint of nasolacrimal duct obstruction (NLDO) in adults. The precise pathogenesis of NLDO is still unknown, but inflammatory processes are believed to be predisposing factors. Endoscopic dacryocystorhinostomy (EN-DCR) is an effective surgical technique for treating symptomatic NLDO. The purpose of the procedure is to relieve the patient's symptoms by creating an opening, ie, a rhinostoma, between the lacrimal sac and the nasal cavity. Although the success rates after EN-DCR are high, the procedure sometimes fails due to onset of a fibrotic process at the rhinostomy site. The aim of this prospective comparative study was to investigate inflammation-related gene expression in the nasal mucosa at the rhinostomy site.MethodsTen participants were consecutively recruited from eligible adult patients who underwent primary powered EN-DCR (five patients) or septoplasty (five controls). Nasal mucosa specimens were taken from the rhinostomy site at the beginning of surgery for analysis of gene expression. Specimens were taken from the same site on the lateral nasal wall for controls. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was performed for the inflammatory genes interleukin (IL)-6, IL-1β, and CCL2, and because of a clear trend of increased inflammation in the EN-DCR samples, a wider PCR array was performed to compare inflammation-related gene expression in EN-DCR subjects and corresponding controls.ResultsOur qRT-PCR results revealed a clear trend of increased transcription of IL-6, IL-1β, and CCL2 (P=0.03). The same trend was also evident in the PCR array, which additionally revealed notable differences between EN-DCR subjects and controls with regard to expression of several other inflammation-related mediators. At 6-month follow-up, the success rate after primary EN-DCR was 60%, ie, in three of five patients.ConclusionThe present study demonstrates that there is an intense inflammation gene expression response in the nasal mucosa of patients undergoing EN-DCR.

Project description:BackgroundVenous thromboembolism (VTE) is the most common preventable cause of 30-day post-operative mortality, with many events occurring after hospital discharge. High-level evidence supports post-discharge VTE chemoprophylaxis following abdominal/pelvic cancer resection; however, some studies support a more tailored approach. Our objectives were to (1) identify risk factors associated with post-discharge VTE in a large cohort of patients undergoing colorectal cancer resection and (2) develop a post-discharge VTE risk calculator.MethodsPatients who underwent colorectal cancer resection from 2012 to 2016 were identified from ACS NSQIP colectomy and proctectomy procedure-targeted modules. Multivariable logistic regression was used to identify factors associated with post-discharge VTE. Incorporating pre-operative, intra-operative, and post-operative variables, a post-discharge VTE risk calculator was constructed and validated.ResultsOf 51,139 patients, 387 (0.76%) developed post-discharge VTE. Pre-operative factors associated with post-discharge VTE included BMI (e.g., morbidly obese OR 2.27, 95% CI 1.65-3.12 vs. normal BMI), and thrombocytosis (OR 1.41, 95% CI 1.03-1.92). Intra-operative factors included operative time (4-6 h OR 1.56, 95% CI 1.12-2.17; > 6 h, OR 1.85, 95% CI 1.21-2.84, vs. < 2 h), and type of operation (e.g., open partial colectomy OR 1.67, 95% CI 1.30-2.16 vs. laparoscopic partial colectomy). Post-operative factors included anastomotic leak (OR 2.05, 95% CI 1.31-3.21) and post-operative ileus (OR 1.39, 95% CI 1.07-1.79). Using the risk calculator, the predicted probability of post-discharge VTE ranged from 0.04 to 10.29%. On a 10-fold cross validation, the calculator's mean C-Statistic was 0.65.ConclusionsPatient-specific factors are associated with varying rates of post-discharge VTE. We present the first post-discharge VTE risk calculator designed for use at the time of discharge following colorectal cancer resection.

Project description:The National Institute for Health and Care Excellence (NICE) state that acute kidney injury (AKI) is seen in 13-18% of all people being admitted to hospital and that other patients will further go on to develop AKI during their time in hospital, with around 30-40% being in the operative setting. AKI has an estimated inpatient mortality of 20-30% in the UK and can lead to long-term morbidities like chronic kidney disease.[2] AKI is under-recognised and badly managed despite its prevalence and seriousness, with NCEPOD report stating that only 50% of patients with AKI received good care, that there was poor assessment of risk factors for AKI, and there was an unacceptable delay in recognising post-admission AKI in 43% of patients.[4] Baseline data collected on the urology ward in Ninewells Hospital, showed that only five of 22 (23%) patients undergoing urological surgery had post-operative creatinine measured on the ward within 48 hours (the primary method for detecting AKI). Excluding patients who were discharged the same day 5/16 (31%) received the blood test. The aim of the project was to increase the number of patients returning to ward 9 post-surgery who receive a serum creatinine measurement within two days of their urological surgery, excluding daycases. Specifically, we wanted the reliability of this measurement to be 95% or over in ward 9 by 30 July 2014. This was to be done by raising awareness around AKI on ward 9 and changing protocol so that every patient staying on ward 9 beyond their day of surgery should receive a post-operative creatinine. This would be tested for a set amount of time to see if patients with AKI were being missed. Despite not being able to implement a set protocol, the percentage of patients receiving post-operative creatinine measurements on ward 9 after a urological surgery still increased significantly. By interacting with the urology team and presenting our data, the knowledge and comprehension of the problem was altered. This lead to a change in culture and a significant increase in the number of post-operative creatinine measurements being taken. Through building relationships on the ward and sharing our data and knowledge there was an increase from 27% of patients receiving post-op creatinine in our first week of collecting data, to 87% in our last week on ward 9. However, without a set tool or change in protocol this change appears to have not been sustainable as the percentage dropped to 42% two weeks later.
