Per oral endoscopic myotomy: early experience and safety of a multispecialty approach.

BACKGROUND: Per oral endoscopic myotomy (POEM) has gained increasing popularity for treating achalasia. A multidisciplinary approach may allow safe and early adoption of POEM into clinical practice. MATERIALS AND METHODS: We performed a retrospective review of our initial POEM cases. All procedures were performed by a team of interventional gastroenterologist and thoracic surgeon. We analyzed demographics, comorbidities, achalasia subtypes, length of hospital stay, duration of surgery, morbidity, mortality, length of myotomy, preoperative and postoperative Eckardt scores. RESULTS: Thirty-one consecutive patients underwent POEM during the 24-month period from January 2014 to December 2015. Eighteen patients (58%) had prior non-operative interventions. Average duration of follow-up was 9.6 months. Seventeen patients (66.8%) had follow-up of 12 months and longer. Average preoperative Eckardt score was 6.3 (3-10), median 6. Average postoperative Eckardt score was 1.4 (0-8), median 1, in 1 month and an average 2.2, median 1, in 1 year. Patients with type III achalasia were most refractory to treatment, while patients with type II had the best results. Average LOS was 1.3 days (1-5), median 1 day. Average DOS was 106 min (60-148), median 106. Average LOM was 13 cm (10-15), with median of 13 cm. We had one 30-day mortality secondary to coronary artery disease. Four patients had prior Heller myotomies and underwent a posterior myotomy during POEM, with outcomes similar to patients with no prior myotomy. CONCLUSIONS: We demonstrated safety and efficiency of a multispecialty approach for achalasia with POEM with a low rate of complications.

Natural history of retained surgical items supports the need for team training, early recognition, and prompt retrieval.

BACKGROUND: Unintentionally retained items feature prominently among surgical "never events." Our knowledge of these rare occurrences, including natural history and intraoperative safety omission or variance (SOV) profile, is limited. We sought to bridge existing knowledge gaps by presenting a secondary analysis of a multicenter study focused on these important aspects of retained surgical items (RSIs). METHODS: This is a post hoc analysis of results from a multicenter retrospective study of RSIs between January 2003 and December 2009. After excluding previously reported intravascular RSIs (n = 13), a total of 71 occurrences were analyzed for (1) item location and type; (2) time to presentation and/or discovery; (3) presenting signs and symptoms; (4) procedure and incision characteristics; (5) pathology reports; and (6) patterns of SOVs abstracted from medical and operative records. These SOV were then grouped into individual vs team errors and single- vs multifactorial occurrences. RESULTS: Among 71 cases, there were 48 women and 23 men. Mean patient age was 49.7 ± 17.5 years (range 19 to 83 years). Mortality was 4 of 71 (5.63%, only 1 attributable to RSI). Twelve cases (16.9%) occurred at nonparticipating referring hospitals. Most RSI procedures (62%) occurred on the day of hospital admission. The median time from index RSI case to retained item removal was 2 days (range <1 to >3,600 days, n = 63). Abdominal RSIs predominated, and plain radiography was the most common identification method. Most RSIs removed early (<24 hours, n = 23) were asymptomatic. The most common clinical/diagnostic findings in the remaining group were focal pain (n = 22), abscess/fluid collection (n = 18), and mass (n = 8). Most common pathology findings included exudative reaction (n = 22), fibrosis (n = 17), and purulence/abscess (n = 15). On detailed review of intraprocedural events, most RSI cases were found to involve team/system errors (50 of 71) and 2 or more SOVs (37 of 71). Isolated human error was seen in less than 10% of cases. CONCLUSIONS: The finding that most operations complicated by RSIs were found to involve team/system errors and 2 or more SOVs emphasizes the importance of team safety training. The observation that early RSI removal minimizes patient morbidity and symptoms highlights the need for prompt RSI identification and treatment. The incidence of inflammation-related findings increases significantly with longer retention periods.

Wind disasters: A comprehensive review of current management strategies.

Wind disasters are responsible for tremendous physical destruction, injury, loss of life and economic damage. In this review, we discuss disaster preparedness and effective medical response to wind disasters. The epidemiology of disease and injury patterns observed in the early and late phases of wind disasters are reviewed. The authors highlight the importance of advance planning and adequate preparation as well as prompt and well-organized response to potential damage involving healthcare infrastructure and the associated consequences to the medical response system. Ways to minimize both the extent of infrastructure damage and its effects on the healthcare system are discussed, focusing on lessons learned from recent major wind disasters around the globe. Finally, aspects of healthcare delivery in disaster zones are reviewed.

Retained surgical items: a problem yet to be solved.

BACKGROUND: Retained surgical items (RSI) continue to occur. Large RSI studies are few due to low RSI frequency in single institutions and the medicolegal implications. Consequently, RSI risks are not fully defined, with discrepancies persisting among published studies. The goals of this study were to better define risk factors for RSI, to clarify previously discrepant risk factors, and to evaluate other potential contributors to RSI occurrence, such as trainee presence during an operation. STUDY DESIGN: Multicenter case-match study of RSI risk factors was conducted between January 2003 and December 2009. Cases complicated by RSI were identified at participating centers using clinical quality improvement and adverse event reporting data. Case match controls (non-RSI) were selected from same or similar-type cases performed at each respective institution. Retained surgical item risk factors were evaluated by univariate and multivariate conditional logistic regression. RESULTS: Fifty-nine RSIs and 118 matched controls were analyzed (RSI incidence 1 in 6,975 or 59 in 411,526). Retained surgical items occurred despite use of confirmatory x-rays (13 of 27 instances) and/or radiofrequency tagging (2 of 32 instances). Among previously discrepant results, we confirmed that body mass index, unexpected intraoperative events, and procedure duration were associated with increased RSI risk. The occurrence of any safety variance, and specifically an incorrect count at any time during the procedure, was associated with elevated RSI risk. Trainee presence was associated with 70% lower RSI risk compared with trainee absence. CONCLUSIONS: Longer duration of surgery, safety variances, and incorrect counts during the procedure result in elevated RSI risk. The possible positive influence of trainee presence on RSI risk deserves additional study. Our findings highlight the need for zero tolerance for safety omissions, continued study and development of novel approaches to RSI reduction, and establishing anonymous RSI reporting systems to better track both the incidence and risks associated with this problem, which has yet to be solved.

Intravascular retained surgical items: a multicenter study of risk factors.

INTRODUCTION: Retained surgical items (RSIs) have been previously studied in patients undergoing major surgical procedures. This is the first study that specifically examines potential risk factors for intravascular RSI (ivRSI). METHODS: Multicenter retrospective review of 83 RSIs was performed. Among these, 13 cases involved ivRSI. Cases in the ivRSI group were compared with a group of similar control cases to determine potential risk factors for ivRSI, including procedural factors (urgency and complicating factors), patient factors (body mass index), equipment failure (structural or functional), and safety variances. Fisher's exact testing was performed. RESULTS: Thirteen ivRSI cases and 14 controls were examined. There were no differences between the two groups with regard to age, gender, or body mass index. ivRSI items included guide wires (8/13), catheter/catheter fragments (4/13), and a coil (1/13). The incidence of unexpected procedural factors was significantly higher among ivRSI cases (10/13) than among controls (3/14) (P < 0.007). Equipment failure occurred in five ivRSI cases, with none among controls (P < 0.016). There were no differences between the two groups with regard to number of urgent procedures, bleeding >500 mL, evening procedures, or trainee involvement. Both groups had a very high proportion of safety variances (8 in ivRSI and 11 in control group, P = not significant). In addition, seven of 13 ivRSIs were missed on initial confirmatory postprocedural imaging. DISCUSSION: Unexpected procedural factors and equipment failure are significantly associated with ivRSI. Of concern, over half of all ivRSIs were missed on confirmatory postprocedural imaging. Strict adherence to established protocols and stringent radiographic review for intravascular procedures is required to prevent ivRSI.

Civilian nuclear incidents: An overview of historical, medical, and scientific aspects.

Given the increasing number of operational nuclear reactors worldwide, combined with the continued use of radioactive materials in both healthcare and industry, the unlikely occurrence of a civilian nuclear incident poses a small but real danger. This article provides an overview of the most important historical, medical, and scientific aspects associated with the most notable nuclear incidents to date. We have discussed fundamental principles of radiation monitoring, triage considerations, and the short- and long-term management of radiation exposure victims. The provision and maintenance of adequate radiation safety among first responders and emergency personnel are emphasized. Finally, an outline is included of decontamination, therapeutic, and prophylactic considerations pertaining to exposure to various radioactive materials.
