Liver ultrasound: A key procedure in the surgeon's toolbox.

Intraoperative liver ultrasound (US) is an imperative adjunctive procedure during any liver surgical procedure. Intraoperative US can be used to confirm preoperative findings, to identify new findings, and to guide the conduct of the procedure. A major barrier to incorporation of US into the surgeon's toolbox is training and education. A standardized training program for surgical fellows has been developed based on the mastery learning framework.

Detrimental Effects of Filling Laryngotracheal Airways To Excessive Pressure (DEFLATE-P): a quality improvement initiative.

BACKGROUND: This quality improvement (QI) project was performed at a single center to determine the incidence of postoperative complications associated with use of cuffed airway devices. An educational program was then completed that involved training our anesthesia providers about complications related to excessive cuff pressure and how to utilize a quantitative cuff pressure measurement device (manometer). The impact of this educational initiative was assessed by comparing the incidence of postoperative complications associated with the use of airway devices before and after the training period. METHODS: After approval by our institution's Institutional Review Board, a pre-intervention (baseline) survey was obtained from 259 adult patients after having undergone surgery with general anesthesia with the use of an endotracheal tube (ETT) or laryngeal mask airway (LMA). Survey responses were used to determine the baseline incidence of sore throat, hoarseness, and dysphagia. Once these results were obtained, education was provided to the anesthesia department members addressing the complications associated with excessive cuff pressures, appropriate cuff pressures based on manufacturer recommendations, and instructions on the use of a quantitative monitor to determine cuff pressure (manometry). Clinical care was then changed by requiring intraoperative cuff pressure monitoring throughout our institution for all surgical patients. After this educational period, 299 patients completed the same survey describing postoperative airway complications. RESULTS: The use of manometry reduced the incidence of moderate-to-severe postoperative sore throat in the pre- vs. post-intervention groups (35 patients vs 31 patients, p = 0.045), moderate to severe hoarseness (30 patients vs 13, patients p = 0.0001), and moderate-to-severe dysphagia (13 patients vs 5 patients, p = 0.03). CONCLUSION: Caring for patients in the perioperative setting frequently entails placement of an airway device. This procedure is associated with several potential complications, including sore throat, coughing, and vocal cord damage. Our quality improvement initiative has shown that intraoperative management of intra-cuff pressure based on manometry is feasible to implement in clinical practice and can reduce postoperative airway complications.

Consequences of Increasing Complexity in Anorectal Surgery Performed at an Academic Center.

BACKGROUND: Anorectal surgery encompasses a wide range of procedures with varying complexity. The Accreditation Council for Graduate Medical Education Review Committee for Colon and Rectal Surgery recommends minimum case numbers (60) for 1-year specialty trainees in 6 categories of anorectal surgery, with definitions for procedural complexity. OBJECTIVE: The purpose of this study was to assess the scope of anorectal procedures and propose a stratification of procedures based on a consensus of levels of difficulty, as well as to identify a predictive charge cutoff suggestive of procedural complexity. DESIGN: This was a retrospective review. SETTINGS: The study was conducted at a tertiary academic center. PATIENTS: Patients undergoing anorectal procedures between January 2011 and December 2014 identified by Current Procedural Terminology coding were entered into 6 categories. Codes were stratified as routine or complex based on an assessment of perioperative care and technical expertise required. Patients with an abdominal portion to any procedure were excluded. MAIN OUTCOMES MEASURES: The study measured distribution of complexity in anorectal surgical procedures and procedural charge associated with differentiating routine from complex procedures. RESULTS: Seven colorectal surgeons performed 2483 anorectal procedures (mean = 620 per year). Mean age was 48 ± 16 years. Forty six (64%) of 71 procedures were classified as routine and 25 (36%) of 71 as complex. Most disease processes had subsets with routine or complex procedures, whereas all of the procedures performed for fecal incontinence or advanced anorectal techniques were considered complex. Fistula procedures and transanal excisions were most heterogeneous, with a high procedural complexity rate (37% and 50%). After a procedural complexity rating, intraclass correlation by 6 surgeons was 0.70, demonstrating good correlation. Receiver operating curve assessments of consensus categorization according to billing codes revealed $553 as the optimal cutoff between routine and complex procedures. LIMITATIONS: This was a single-institution retrospective review. CONCLUSIONS: Colorectal residents may benefit from anorectal case stratification, because it serves as a dialogue for those interested in complex anorectal surgery during training. Surgeon categorization of procedures correlates well with a charge-based model of complexity. See Video Abstract at http://links.lww.com/DCR/A806.

Myoma Imaging by Gynecologic Surgeons Training in Intraoperative Ultrasound Technique.

STUDY OBJECTIVE: To compare preoperative transvaginal ultrasound (TVUS) and magnetic resonance imaging (MRI) with intraoperative ultrasound (IOUS) in surgeons first learning to use this technique. DESIGN: A prospective study of IOUS accuracy for mapping the size and location of myomas compared with TVUS or MRI (Canadian Task Force classification II-2). SETTING: Five University of California academic centers (Davis, Irvine, Los Angeles, San Diego, and San Francisco). PATIENTS: Twenty-six premenopausal women seeking uterine-sparing surgical treatment of myomas. Eligible participants could have no more than 6 myomas ≥2 cm and <10 cm and a uterine size no larger than 16 weeks by pelvic examination. INTERVENTIONS: Measurement of myomas by IOUS followed by radiofrequency ablation (RFA) of fibroids. MEASUREMENTS AND MAIN RESULTS: Eligible participants had to have imaging with TVUS or MRI within the last year to assess myoma characteristics. During the RFA operation, surgeons who had undergone a 1-day training on RFA and IOUS measured all myomas visualized with IOUS. Surgeons measured more myomas than were reported on MRI (12 on MRI and 16 on IOUS) or TVUS (41 on TVUS and 62 on IOUS) in all positions (anterior, posterior, lateral, and fundal). In particular, they identified more myomas <2 cm (4 on MRI, 9 on IOUS, 1 on TVUS, and 19 on IOUS). They located 2.3 times as many myomas in the anterior position as TVUS. For the myomas ≥2 cm identified by IOUS and MRI or IOUS and TVUS, there was no statistically significant difference in the mean myoma number or the mean myoma diameter measurements. CONCLUSION: Surgeons first learning to use IOUS detect the same number of myomas ≥2 cm as identified by TVUS and MRI and find a greater number of myomas <2 cm on IOUS compared with radiologist-reported TVUS.

Ethical and legal duty of anesthesiologists regarding Jehovah's Witness patient: care protocol / Dever ético e legal do anestesiologista frente ao paciente testemunha de Jeová: protocolo de atendimento

Abstract Background and objectives: Jehovah's Witnesses patients refuse blood transfusions for religious reasons. Anesthesiologists must master specific legal knowledge to provide care to these patients. Understanding how the Law and the Federal Council of Medicine treat this issue is critical to know how to act in this context. The aim of this paper was to establish a treatment protocol for the Jehovah's Witness patient with emphasis on ethical and legal duty of the anesthesiologist. Content: The article analyzes the Constitution, Criminal Code, resolutions of the Federal Council of Medicine, opinions, and jurisprudence to understand the limits of the conflict between the autonomy of will of Jehovah's Witnesses to refuse transfusion and the physician's duty to provide the transfusion. Based on this evidence, a care protocol is suggested. Conclusions: The Federal Council of Medicine resolution 1021/1980, the penal code Article 135, which classifies denial of care as a crime and the Supreme Court decision on the HC 268,459/SP process imposes on the physician the obligation of blood transfusion when life is threatened. The patient's or guardian's consent is not necessary, as the autonomy of will manifestation of the Jehovah's Witness patient refusing blood transfusion for himself and relatives, even in emergencies, is no not forbidden.

Resumo Justificativa e objetivos: Os pacientes testemunhas de Jeová recusam transfusão sanguínea por motivos religiosos. O anestesiologista deve dominar conhecimentos jurídicos específicos para atender esses pacientes. Entender como o direito e o Conselho Federal de Medicina tratam essa questão é fundamental para saber agir dentro desse contexto. O objetivo deste artigo foi estabelecer um protocolo de atendimento do paciente testemunha de Jeová com ênfase no dever ético e legal do anestesiologista. Conteúdo: O artigo analisa a Constituição, o Código Penal, resoluções do Conselho Federal de Medicina (CFM), pareceres e jurisprudência para entender os limites do conflito entre a autonomia de vontade da testemunha de Jeová em recusar transfusão e a obrigação do médico em transfundir. Baseado nessas evidências um protocolo de atendimento é sugerido. Conclusões: A resolução do CFM 1021/1980, o Código Penal no artigo 135, que classifica como crime a omissão de socorro, e a decisão do Supremo Tribunal de Justiça sobre o processo HC 268.459/SP impõem ao médico a obrigação de transfusão quando houver risco de vida. Não é necessário concordância do paciente ou de seu responsável, pois não é proibida a manifestação de vontade do paciente testemunha de Jeová ao recusar transfusão sanguínea para si e seus dependentes, mesmo em emergências.

The Feasibility of Real-Time Intraoperative Performance Assessment With SIMPL (System for Improving and Measuring Procedural Learning): Early Experience From a Multi-institutional Trial.

PURPOSE: Intraoperative performance assessment of residents is of growing interest to trainees, faculty, and accreditors. Current approaches to collect such assessments are limited by low participation rates and long delays between procedure and evaluation. We deployed an innovative, smartphone-based tool, SIMPL (System for Improving and Measuring Procedural Learning), to make real-time intraoperative performance assessment feasible for every case in which surgical trainees participate, and hypothesized that SIMPL could be feasibly integrated into surgical training programs. METHODS: Between September 1, 2015 and February 29, 2016, 15 U.S. general surgery residency programs were enrolled in an institutional review board-approved trial. SIMPL was made available after 70% of faculty and residents completed a 1-hour training session. Descriptive and univariate statistics analyzed multiple dimensions of feasibility, including training rates, volume of assessments, response rates/times, and dictation rates. The 20 most active residents and attendings were evaluated in greater detail. RESULTS: A total of 90% of eligible users (1267/1412) completed training. Further, 13/15 programs began using SIMPL. Totally, 6024 assessments were completed by 254 categorical general surgery residents (n = 3555 assessments) and 259 attendings (n = 2469 assessments), and 3762 unique operations were assessed. There was significant heterogeneity in participation within and between programs. Mean percentage (range) of users who completed ≥1, 5, and 20 assessments were 62% (21%-96%), 34% (5%-75%), and 10% (0%-32%) across all programs, and 96%, 75%, and 32% in the most active program. Overall, response rate was 70%, dictation rate was 24%, and mean response time was 12 hours. Assessments increased from 357 (September 2015) to 1146 (February 2016). The 20 most active residents each received mean 46 assessments by 10 attendings for 20 different procedures. CONCLUSIONS: SIMPL can be feasibly integrated into surgical training programs to enhance the frequency and timeliness of intraoperative performance assessment. We believe SIMPL could help facilitate a national competency-based surgical training system, although local and systemic challenges still need to be addressed.

The implementation of a surgeon-directed quality improvement strategy in breast cancer surgery.

BACKGROUND: The investigators designed a sustained, surgeon-directed, iterative project to improve the quality of breast cancer surgery in south central Ontario. METHODS: The strategy included audit and feedback of surgeon-selected quality indicators, workshops, and tailoring interviews. Workshops were held to discuss quality improvement strategies, select quality indicators, review audited results, and select interventions for subsequent implementation. Semistructured tailoring interviews were conducted to identify facilitators and barriers to improved quality. All presentations and results were disseminated to all surgeons performing breast surgery in the study region. RESULTS: Forty-four surgeons performing breast surgery across 12 hospitals are involved in the project. Five workshops have been held since 2005. Surgeons' enthusiasm and involvement in the project have been positive. Interim results demonstrated that over 4 audit cycles (2006-2010), the preoperative core biopsy rate increased from 73% to 92%. The tailoring interviews indicated that 18 of 21 surgeons performed preoperative core biopsies. CONCLUSIONS: This project highlights the feasibility of a surgeon-directed, iterative quality improvement strategy in breast cancer surgery. Interim results demonstrate consistent improvements in a key selected quality indicator.

Capturing intra-operative safety information using surgical wikis.

BACKGROUND: Expert surgeons use a mass of intra-operative information, as well as pre- and post-operative information to complete operations safely. Trainees acquired this intra-operative knowledge at the operating table, now largely diminished by the working time directive. Wikis offer unexplored approaches to capturing and disseminating expert knowledge to further promote safer surgery for the trainee. METHODS: Grafting an abdominal aortic aneurysm represents a potentially high-risk operation demanding extreme safety measures. Operative details, presented on a surgical wiki in the form of a script and content analysed to classify types of safety information. RESULTS: The intra-operative part of the script contained 2,743 items of essential surgical information, comprising 21 sections, 405 steps and 2,317 items of back-up information; 155 (5.7%) of them were also specific intra-operative safety checks. Best case scenarios consisted of 1,077 items of intra-operative information, 69 of which were safety checks. Worse case and rare scenarios required a further 1,666 items of information, including 86 safety checks. CONCLUSIONS: Wikis are relevant to surgical practice specifically as a platform for knowledge sharing and optimising the available operating time of trainees, as a very large amount of minutely detailed information essential for a safe major operation can be captured.

Resident perceptions of the impact of paging on intraoperative education.

Our purpose was to evaluate the impact of paging on perceptions of intraoperative learning. Intraoperative logs of pager interruptions were kept by surgical residents at a university hospital over a 30-day period. The postgraduate year, number of pages, category of caller, reason for call, and level of urgency were recorded during each operation. At the conclusion of each operation, residents also completed a two-item survey with responses on a 5-point scale (1 = strongly disagree to 5 = strongly agree), querying if interruptions negatively impacted the intraoperative experience and if a message taken by a third party was effective in limiting interruptions. Logs were completed for 124 of 204 operations. Fifty-five per cent of operations were interrupted at least once with 49 per cent interrupted two to five times and 6 per cent were interrupted six or more times. Junior residents had 69 per cent of their operations interrupted compared with 39 per cent of senior residents (P = 0.001). Ninety-two per cent of pages were nonurgent. Residents did not perceive pager interruptions negatively impacted their educational experience (mean 2.3) but were neutral with respect if messages taken by a third party decreased interruptions (mean 3.8). Although our hypothesis was that pager interruptions were frequent and disrupt resident education, our data demonstrate the opposite.

Implementation of an intraoperative clinical experience for senior level baccalaureate nursing students.

Perioperative nursing is a specialty that has been eliminated from many nursing education programs. With the loss of perioperative clinical experiences, the number of students pursuing a career in perioperative nursing after graduation has declined. A faculty member at one Midwestern school of nursing developed and implemented a perioperative clinical experience for senior-level baccalaureate nursing students in a critical care nursing course. This program, developed with the assistance of four local hospitals and the college of nursing, included an eight-hour OR orientation and 56 clinical hours. Students were placed in the OR under preceptor guidance and supervision. Feedback from evaluations was positive and provided recommendations for improving the program, in particular, to allow more clinical hours and more hands-on experience for the students.

Mentored trainees obtain comparable operative results to experts in complex laparoscopic colorectal surgery.

PURPOSE: The aim of this study is to evaluate the impact of an expert monitoring on the quality and results of laparoscopic reversal of Hartmann's procedure (LRHP) performed by trainee surgeons by comparing their results to the expert's outcomes. METHODS: Forty-two LRHP were performed between 2000 and 2008 following a step-by-step, standardised, full laparoscopic procedure. Patients operated upon by a senior surgeon were compared to patients operated upon by trainee surgeons while being mentored by the senior surgeon. Operative time, conversion, complications and post-operative outcome were measured. RESULTS: Each group included 21 patients. All patients underwent LRHP successfully. Two procedures were converted. No significant difference was observed between the expert and the trainees: operative time, 132 min (SD ± 50) vs. 131 min (SD ± 47) and complications (2-14%), 4 vs. 2. Three complications required re-operation, and three other were treated medically, including one dilatation of an anastomosis. Post-operative outcomes were comparable (oral intake, 3 vs. 2 days; post-operative hospital stay, 6 vs. 7.5 days); no mortality occurred. CONCLUSIONS: Standardisation simplifies this difficult laparoscopic procedure and offers the same outcome whether it is performed by an expert or by mentored trainees. The complications were comparable to those occurring at experienced centres (anastomotic leak or stricture, ureteral injury, re-operation). The expert mentoring does not prevent all complications but can solve intra-operative technical problems, thus improving the trainee's confidence. Mentoring should be promoted as it can be performed locally or remotely using modern interactive technology.

Decision-making and technical factors account for the learning curve in complex surgery.

INTRODUCTION: The general public, the legal profession, patients and relatives expect best practice and have difficulty with the concept of a learning curve in surgical interventions. However, it is improbable that technical and innovative skills can be developed, or optimized, without some aspects of learning by experience and indeed 'risk taking'. PATIENTS AND METHOD: A single surgeon experience with a novel, complex, surgical procedure for peritoneal malignancy is described and compared with recent literature reports on the surgical learning curve. In total, 100 of 242 (41%) patients referred underwent a laparotomy. The 100 were divided into three numerically equal groups of 33, 33 and 34 cases, and the proportions undergoing surgery, mortality and major morbidity rates for the three groups were analysed. RESULTS: The numbers undergoing surgery were 33/54 (61%), 33/96 (34%) and 34/92 (37%). The mortality was 6/33 (18%), 1/33 (3%) and 1/33 (3%), and the major morbidity rates were 9/33 (27%), 2/33 (6%) and 0/34 (0%) in the three groups. CONCLUSIONS: The main components of the learning curve were considered to be decision-making and technical factors. A mechanism to reduce the surgical learning curve is suggested involving teamwork, and at least two experienced surgeons involved in all major surgical interventions. Decision-making and technical factors account for the learning curve in complex surgery.
