American Society of Anesthesiologists class and Charlson's Comorbidity index as predictors of postoperative colorectal anastomotic leak: a single-institution experience

Background

The American Society of Anesthesiologists (ASA) physical status classification and Charlson comorbidity index (CCI) was adopted to assess patients' physical condition before surgery. Studies suggest that ASA score and CCI might be a prognostic criterion (indicator) for patient outcome. The aim of this study is to determine if ASA classification and CCI can determine the risk of anastomotic leaks (AL) in patients who underwent colorectal surgery.

Methods

A retrospective analysis of 505 consecutive colorectal resections with primary anastomoses between 2008 and 2012 was performed at a university hospital. ASA score, CCI, surgical procedure, length of stay, age, body mass index (BMI), comorbidities, and postoperative outcomes were analyzed.

Results

Two hundred sixty-five patients had an ASA score of I and II, 227 patients had an ASA score of III, and 13 patients had an ASA score of IV. A total of 19 patients had an anastomotic leak (ASA I–II: 5 patients, 1.9%; ASA III: 12 patients, 5.58%; ASA IV: 2 patients, 18.18%). A higher ASA score was significantly associated with AL on further analysis (OR: 2.99, 95% CI: 1.345–6.670, P = 0.007). When matched for age, BMI, and CCI on logistic regression analysis, increased ASA level was independently related to an increased likelihood of leak (OR_steroids = 14.35, P < 0.01; OR_{ASA_III v I–II} = 2.02, P = 0.18; OR_{ASA_IVvI–II} = 8.45, P = 0.03). There were no statistically significant differences in means between the leak and no-leak patients with respect to age (60.69 versus 65.43, P = 0.17), BMI (28.03 versus 28.96, P = 0.46), and CCI (6.19 versus 7.58, P = 0.09).

Conclusions

ASA score, but not CCI, is independently associated with anastomotic leak. Patients with a high ASA class should be closely followed postoperatively for AL after colorectal operations.     

The society for cardiovascular angiography and interventions structural heart disease early career task force survey results: Endorsed by the society for cardiovascular angiography and interventions

Over the last decade, structural heart disease interventions have emerged as a new field in interventional cardiology. Currently, the Accreditation Council for Graduate Medical Education accredited interventional cardiology fellowship programs in the United States provide high‐quality and well established training curriculum in coronary and peripheral interventions, but training in structural interventions remains in its infancy. The current survey seeks to collect relevant information and assess the opinion of interventional cardiology program directors in ACGME‐accredited institutions that are actively involved in structural interventional training. Our study describes the actual number of structural procedures performed by interventional cardiology fellows in ACGME‐accredited programs, the form of the structural training today and the suggestions from program directors who are actively trying to integrate structural training in the interventional cardiology fellowship programs. © 2012 Wiley Periodicals, Inc.     

The application of TachoSil® for sealing colorectal anastomosis: a feasibility study

Aim Anastomotic leakage is a frequent postoperative complication of colorectal resection. This nonrandomized study assessed the feasibility and safety of applying a haemostatic tissue sealant (TachoSil®) to colorectal anastomoses following resection. Method TachoSil was applied as reinforcement of the anastomotic line after laparoscopic or open colorectal resection. The primary endpoint was the proportion of patients for whom TachoSil application was considered feasible by both the investigator and an independent external assessor. Application was considered feasible if TachoSil fully adhered, covered ≥ 1 cm beyond the margin of the anastomotic line and patches overlapped by ≥ 1 cm. Individual investigator assessment of feasibility and adverse events 30 days after surgery were also recorded. Results Twenty‐five patients underwent anterior resection (seven open lower, nine open middle‐upper, four laparoscopic lower and five laparoscopic middle‐upper). In six cases a video‐recording was not available because of technical problems. The primary endpoint was met in 12 of the remaining 19 patients (63%; 95% CI 38–84%), while in the other seven the application was recorded as not feasible because the assessor was unable to see the entire anastomosis. No application was assessed as unfeasible on the basis of visual evidence. When assessed by the investigator alone, TachoSil was considered feasible in all but one instance (96%; 95% CI 80–100%). There were 45 adverse events, of which 10 were serious. None was considered related to TachoSil. No deaths were reported. Conclusion Application of TachoSil to reinforce the anastomotic line in colorectal resections appears to be feasible and well tolerated.     

Traumatic brain injury: review of current management strategies

Head injury is a common condition with a high morbidity and mortality. Serious intracranial haematomas require early recognition and evacuation to maximise chances of independent outcomes. Recent organisational changes have promoted the development of trauma units and major trauma centres where patients can go through triage and be managed in an appropriate environment, and the development of management pathways in intensive treatment units has resulted in improvements in the outcome of traumatic brain injuries. Evidence for the treatment of cerebral perfusion pressure, and management of hyperventilation, osmotherapy, tracheostomy, and leakage of cerebrospinal fluid (CSF) has accumulated during the last decade and is important in the management of patients in all clinical settings. Since head injury is commonly associated with maxillofacial injuries, this review will be relevant to all who deal with this aspect of trauma.     

Efficacy of Human Fibrinogen-Thrombin Patch (TachoSil) Clinical Application in Upper Gastrointestinal Cancer Surgery

Background: Previous studies investigated the efficacy and applicability of tissue adhesives in gastrointestinal surgery while no evidence is available to date about a novel compound, TachoSil (Takeda, Zurich, Switzerland). The primary aim of this observational study was to assess the effect of new fibrin sealant on the incidence of postoperative complications in a homogeneous group of patients submitted to upper gastrointestinal surgery for cancer. Methods: Two cohorts of 28 and 34 patients undergoing upper gastrointestinal for surgery were compared. In the first cohort, the anastomotic site was treated with TachoSil fibrinogen-thrombin-collagen patches and in the second no collagen sponge or any other hemostatic sealant was used. Postoperative complications and outcomes as well as postoperative biochemical parameters were analyzed. Results: Postoperative complications occurred in 12 patients (35.3%) and 2 patients (7.1%) in control and collagen sponge group respectively (χ² = 3.539, p < 0.05), with no anastomotic leakage in the collagen sponge group. A binary logistic regression analysis showed that the nonuse of collagen sponge [odds ratio (OR) = 0.025, 95% confidence interval (CI) = 0.001–0.457, p = 0.01] was independently associated with postoperative complication occurrence. Conclusions: The addition of fibrinogen-thrombin-collagen sponge patch may reduce postoperative complication rate after upper gastrointestinal surgery for cancer. Further study to delineate the role of TachoSil in gastrointestinal surgery are also needed to demonstrate improved effectiveness and applicability.
