American Society of Metabolic and Bariatric Surgery consensus statement on laparoscopic adjustable gastric band management

BackgroundLaparoscopic adjustable gastric band (LAGB) management continues to be an important part of many metabolic and bariatric surgery practices.ObjectivesTo replace the existing American Society for Metabolic and Bariatric Surgery (ASMBS) LAGB adjustment credentialing guidelines for physician extenders with consensus statements that reflect the current state of LAGB management.SettingASMBS Integrated Health Clinical Issues Committee.MethodsA modified Delphi process using a 2-stage consensus approach was conducted on LAGB management. Thirty-four consensus statements were developed following a literature search on a wide range of LAGB topics. A 5-point Likert scale was implemented to measure consensus agreement with a Delphi panel of 39 expert participants who were invited and agreed to participate in 2 rounds of Delphi questionnaires. Consensus was set a priori at 75% agreement, defined as the proportion of participants responding with agreement (i.e., 4 or 5) or disagreement (i.e., 1 or 2) on the Likert scale.ResultsConsensus was reached on 74% (25 of 34) of the LAGB management statements. In Delphi round 1, 95% (37 of 39) of the participants responded to 34 consensus statements; 21 of the statements (62%) met the 75% criteria for consensus. Thirty-one participants (80%) responded in round 2, shifting the agreement on 4 more statements to the 75% threshold.ConclusionThe ASMBS consensus statement on LAGB management is intended to guide practice with current evidence-based knowledge and professional experience. The ASMBS is not a credentialing body and does not seek to guide credentialing with this document.     

Treatment of stiff-knee gait in cerebral palsy: a comparison by gait analysis of distal rectus femoris transfer versus proximal rectus release

Two groups of patients with cerebral palsy (CP) were studied pre- and postoperatively by gait analysis after proximal release or distal transfer of the rectus femoris for treatment of knee stiffness in swing phase. In the first group studied, 12 patients underwent proximal rectus femoris muscle release. In the second group, 10 patients underwent distal rectus femoris transfer. After surgery, peak knee flexion was increased 9.1 degrees in swing phase by proximal rectus release and 16.2 degrees by distal rectus transfer. Hip motion throughout the gait cycle was not significantly affected by either operation, and no tendency for a crouch gait was observed after either procedure.     

Consensus on resuscitative endovascular balloon occlusion of the Aorta: A first consensus paper using a Delphi method

BackgroundTo further strengthen the evidence base on the use of Resuscitative Endovascular Balloon occlusion of the Aorta (REBOA) we performed a Delphi consensus. The aim of this paper is to establish consensus on the indications and contraindications for the use of REBOA in trauma and non-trauma patients based on the existing evidence and expertise.Study DesignA literature review facilitated the design of a three-round Delphi questionnaire. Delphi panelists were identified by the investigators. Consensus was reached when at least 70% of the panelists responded to the survey and more than 70% of respondents reached agreement or disagreement.ResultsPanel members reached consensus on potential indications, contra-indications and settings for use of REBOA (excluding the pre hospital environment), physiological parameters for patient selection and indications for early femoral access. Panel members failed to reach consensus on the use of REBOA in patients in extremis (no pulse, no blood pressure) and the use of REBOA in patients with two major bleeding sites.ConclusionsConsensus was reached on indications, contra indications, physiological parameters for patient selection for REBOA and early femoral access. The panel did not reach consensus on the use of REBOA in patients in pre-hospital settings, patients in extremis (no pulse, no blood pressure) and in patients with 2 or more major bleeding sites. Further research should focus on the indications of REBOA in pre hospital settings, patients in near cardiac arrest and REBOA inflation times.     

Comparison of rectus femoris transposition with traditional transfer for treatment of stiff knee gait in patients with cerebral palsy

Purpose To assess the outcome of children with cerebral palsy following reposition of the distal rectus femoris tendon for treatment of stiff knee gait. Methods Children with cerebral palsy with stiff knee gait who underwent rectus femoris transfer were studied retrospectively. Inclusion criteria were cerebral palsy of diplegic or quadriplegic type, preoperative and 1 year postoperative three-dimensional motion analysis, and no other surgery except rectus femoris transfer at the time of study. The patients were separated into two groups: in group I, the rectus femoris was transferred to the distal medial hamstring tendons, either the gracilis or the semitendinosus; in group II, the distal tendon of the rectus femoris was transposed laterally and attached to the iliotibial band/intermuscular septum. Results Peak knee flexion during swing phase, total dynamic knee range of motion, knee range of motion during swing phase, and time to peak knee flexion during swing phase were all improved in both groups. Hip and pelvic kinematics were not influenced by the surgery. Velocity, stride length, and cadence were all improved following the surgery. There was no difference between the transfer group and the transposition group. Conclusion These findings suggest that distal transfer of the rectus femoris is effective in improving swing phase knee function by diminishing the mechanical effect of the dysphasic swing phase activity of the rectus femoris, not by converting the rectus femoris to an active knee flexor. No financial support was received for this study.     

Rectus Femoris Transfer Improves Stiff Knee Gait in Children With Spastic Cerebral Palsy

Background  

Stiff knee gait is common among children with ambulatory cerebral palsy (CP). When surgery is indicated, rectus femoris transfer as a primary treatment enhances knee range of motion, reduces time to peak knee flexion, increases peak knee flexion, and reduces toe drag.     

Management of penile cancer patients during the COVID-19 pandemic: An eUROGEN accelerated Delphi consensus study

ObjectivesTo develop an international consensus on managing penile cancer patients during the COVID-19 acute waves. A major concern for patients with penile cancer during the coronavirus disease 2019 (COVID-19) pandemic is how the enforced safety measures will affect their disease management. Delays in diagnosis and treatment initiation may have an impact on the extent of the primary lesion as well as the cancer-specific survival because of the development and progression of inguinal lymph node metastases.Materials and methodsA review of the COVID-19 literature was conducted in conjunction with analysis of current international guidelines on the management of penile cancer. Results were presented to an international panel of experts on penile cancer and infection control by a virtual accelerated Delphi process using 4 survey rounds. Consensus opinion was defined as an agreement of ≥80%, which was used to reconfigure management pathways for penile cancer.ResultsLimited evidence is available for delaying penile cancer management. The consensus rate of agreement was 100% that penile cancer pathways should be reconfigured, and measures should be developed to prevent perioperative nosocomial transmission of COVID-19. The panel also reached a consensus on several statements aimed at reconfiguring the management of penile cancer patients during the COVID-19 pandemic.ConclusionsThe international consensus panel proposed a framework for the diagnostic and invasive therapeutic procedures for penile cancer within a low-risk environment for COVID-19.     

Proximal rectus femoris release surgery is not effective in normalizing hip and pelvic variables during gait in children with cerebral palsy

The purpose of this study was to determine the efficacy of the proximal rectus femoris release to treat hip flexor contractures and hip and pelvic gait deviations in children with spastic cerebral palsy. This study was a retrospective repeated-measures analysis of data collected on two matched groups of patients, those with and without proximal rectus femoris release surgery, seen in our Motion Analysis Laboratory. Proximal rectus release surgery did not improve hip extension, did not decrease anterior pelvic tilt, and did not improve temporal-distance measures of gait in children with cerebral palsy. A multivariate measure, the Hip Flexor Index, was also unchanged. The group of patients without any hip flexor surgery was not different from the rectus femoris release group on hip or pelvic variables before or after surgery. The findings of this study offer no evidence that the proximal rectus femoris release is successful in achieving desired gait outcomes at the hip and pelvis in children with cerebral palsy.     

Italian recommendations on enzymatic debridement in burn surgery

IntroductionNexobrid®, a bromelain-based type of enzymatic debridement, has become more prevalent in recent years. We present the recommendations on enzymatic debridement (Nexobrid®)’s role based on the practice knowledge of expert Italian users.MethodsThe Italian recommendations, endorsed by SIUST (Italian Society of Burn Surgery), on using enzymatic debridement to remove eschars for burn treatment were defined. The definition followed a process to evaluate the level of agreement (a measure of consensus) among selected experts, representing Italian burn centers, concerning defined clinical aspects of enzymatic debridement. The consensus involved a multi-phase process based on the Delphi method.ResultsThe consensus panel included experts from Italy with a combined experience of 1068 burn patients treated with enzymatic debridement. At the end of round 3 of the Delphi method, the panel reached 100% consensus on 26 out of 27 statements. The panel achieved full, strong consensus (all respondents strongly agreed on the statement) on 24 out of 27 statements.DiscussionThe statements provided by the Italian consensus panel represent a “ready to use” set of recommendations for enzymatic debridement in burn surgery that both draw from and complete the existing scientific literature on the topic. These recommendations are specific to the Italian experience and are neither static nor definitive. As such, they will be updated periodically as further quality evidence becomes available.     

The effect of tuning ankle foot orthoses-footwear combinations on gait kinematics of children with cerebral palsy: A case series

Study designCase series.BackgroundAFOs are a commonly prescribed medical device given to children with cerebral palsy (CP) in an attempt to improve their gait. The current literature is equivocal on the effects AFOs have on the gait of children with CP. The vast majority of AFOs issued are not subject to AFO-FC tuning. There are emerging studies investigating the effects tuning AFO-FCs has on the gait of children with CP. However, the research is limited, and there is a lack of quantitative data.ObjectiveTo compare the kinematics of tuned versus non-tuned gait in children with CP.MethodsGait analysis assessment of five children aged between 7–11 years with a diagnosis of CP (one hemiplegic and four diplegic participants, two female, three male, with a Gross Motor Functional Classification System (GMFCS) of 2) at a Gait Analysis Laboratory.ResultsIn comparison to barefoot and non-tuned gait, walking with a tuned AFO-FC produced improvements in several key gait parameters. Including hip flexion and extension, posterior pelvic tilt and knee extension. Results also indicated that the type of gait pattern demonstrated by the participant affected the outcomes of tuning.ConclusionsTuning the AFO-FC of children with CP has the potential to improve hip function, pelvic function, knee extension in stance phase and knee flexion during swing phase and that a non-tuned AFO-FC can potentially decrease hip function, posterior pelvic tilt and increase knee extension.Clinical RelevanceWhilst AFO-FC tuning has been recommended for routine clinical practice, there still remains a paucity of research on the kinematic effects of using a tuned AFO-FC compared to a non-tuned. This paper provides a comparison of kinematics on children with CP, during barefoot, non-tuned and tuned AFO-FC walking with a view to inform clinical practice.     

Patients With Chronic Obstructive Pulmonary Disease Exacerbations: Recommendations for Diagnosis,Treatment and Care

ObjectiveTo describe an evidence- and experience-based expert consensus on the most relevant issues of patients with COPD exacerbations.MethodsThe Delphi technique was used. Evidence was reviewed by a scientific committee and 60 experts. A questionnaire was prepared containing 3 sections: diagnosis of the exacerbator; treatment, and healthcare processes. The survey was answered in 2 rounds by 60 pneumologists on an online platform. Statements were scored on a Likert scale from 1 (total disagreement) to 9 (total agreement). Agreement and disagreement were defined as a score of 7–9 or 1–3, respectively, given by more than two thirds of the participants.ResultsA total of 48 statements were included, one of which was added in the second round. Consensus was reached in 37 items (78.7%) after the first round (agreement), and in 43 (89.5%) after the second round (42 agreement, 1 disagreement). The statements with the highest proportion of experts agreeing were as follows: in exacerbators, chronic bronchial infection favors lung function decline (93.1%); long-acting bronchodilators should not be withdrawn (93.1%); treatment must be personalized if new exacerbations occur despite optimal bronchodilator treatment (96.6%); management must be coordinated between primary care and the respiratory medicine department (93.1%), and patients must be followed up in specific integrated multicomponent programs (94.8%).ConclusionsThe findings of this study could assist in the diagnosis and treatment of COPD exacerbators in our area.     

Eschar removal by bromelain based enzymatic debridement (Nexobrid®) in burns: European consensus guidelines update

IntroductionBromelain-based Enzymatic Debridement has been introduced as an additional concept to the burn surgeon's armamentarium and is best indicated for mid-to deep dermal burns with mixed patterns. Increasing evidence has been published focusing on special regions and settings as well as on limitations of Enzymatic Debridement to improve patient care. To better guide Enzymatic Debridement in view of the increasing experience, there is a need to update the formerly published consensus guidelines with user-orientated recommendations, which were last produced in 2017.MethodsA multi-professional expert panel of plastic surgeons and burn care specialists from twelve European centers was convened, to assist in developing current recommendations for best practices with use of Enzymatic Debridement. Consensus statements were based on peer-reviewed publications and clinical relevance, and topics for re-evaluation and refinement were derived from the formerly published European guidelines. For consensus agreement, the methodology employed was an agreement algorithm based on a modification of the Willy and Stellar method. For this study on Enzymatic Debridement, consensus was considered when there was at least 80 % agreement to each statement.ResultsThe updated consensus guidelines from 2019 refer to the clinical experience and practice patterns of 1232 summarized patient cases treated by the panelists with ED in Europe (2017: 500 cases), reflecting the impact of the published recommendations. Forty-three statements were formulated, addressing the following topics: indications, pain management and anesthesia, large surface treatment, timing of application for various indications, preparation and application, post-interventional wound management, skin grafting, outcome, scar and revision management, cost-effectiveness, patient´s perspective, logistic aspects and training strategies. The degree of consensus was remarkably high, with consensus in 42 out of 43 statements (97.7%). A classification with regard to timing of application for Enzymatic Debridement was introduced, discriminating immediate/very early (≤12 h), early (12−72 h) or delayed (>72 h) treatment. All further recommendations are addressed in the publication.ConclusionsThe updated guidelines in this publication represent further refinement of the recommended indication, application and post-interventional management for the use of ED. The published statements contain detailed, user-orientated recommendations aiming to align current and future users and prevent pitfalls, e.g. for the successful implementation of ED in further countries like the USA. The significance of this work is reflected by the magnitude of patient experience behind it, larger than the total number of patients treated in all published ED clinical trials.     

Consensus conference on laparoscopic appendectomy: development of guidelines

Aim Laparoscopic appendectomy (LA) is not yet unanimously considered the gold standard treatment for appendicitis, despite the increasing use of advanced laparoscopic operations and the high incidence of the disease. Method Due to the results of an audit which classified LA as widespread in Italy, a Consensus Conference was organized, in order to give evidence‐based answers to the most debated problems regarding the operation. After researching the literature, a panel of 20 experts were selected and interviewed on hot topics; a subsequent discussion using the Delphi methodology was utilized in the course of the consensus conference and submitted to the evaluation of an audience of surgeons. Results Checkpoint statements were formulated whenever an agreement was reached. A level of evidence was then assigned to single statements and the process revised by two external reviewers. Conclusion Consensus development guidelines are herein reported and regard diagnostic pathway, diagnostic laparoscopy, indications, behaviour in case of innocent appendix, technical aspects, learning curve; however, some questions remain unsolved due to the lack of evidence.     

External validation of the recommendations of the multidisciplinary consensus about inhaled therapies

The understanding of physicians and the skill of patients in the use of inhalers continues to be inadequate.ObjectiveThe external validation, by an expert panel, of practical clinical recommendations that had been developed in order to improve the knowledge and understanding of correct inhaled therapy use.MethodsAfter a bibliographic review about inhaled therapies, 40 clinical recommendations were proposed. A two-round modified Delphi consensus was used to compare the opinions of a panel of 59 experts about the recommendations, which were grouped into 8 areas: general aspects (4), inhaled drugs (9), pressurized metered-dose and spacer inhalers (6), powder inhalers (4), nebulizers (3), devices for mechanical ventilation (3), inhalers for children (5) and issues related with compliance and education (6).ResultsAfter the first round of the consensus panel, 35 of the 40 recommendations analyzed were accepted. At the end of round 2, agreement was reached in 39 (97.5%). In 8 (20%), the consensus was unanimous (100%). Item 14 was deleted from the recommendations as consensus was not reached.ConclusionsThe external validation by experts in inhaled therapy found a high level of agreement with the clinical recommendations proposed. This consensus provides a tool that could contribute to the improved use of inhalers in our country in the future.     

Correlation between the Gait Deviation Index and gross motor function (GMFCS level) in children with cerebral palsy

Aim

The Gait Deviation Index (GDI) is a score derived from three-dimensional gait analysis (3DGA). The GDI provides a numerical value that expresses overall gait pathology (ranging from 0 to 100, where 100 indicates the absence of gait pathology). The aim of this study was to investigate the association between the GDI and different levels of gross motor function [defined as the Gross Motor Function Classification System (GMFCS)] and to explore if age, height, weight, gender and cerebral palsy (CP) subclass (bilateral and unilateral CP) exert any influence on the GDI in children with unilateral and bilateral spastic CP.

Methods

We calculated the GDI of 109 children [73 % boys, mean age 9.7 years (standard deviation, SD 3.5)] with spastic CP, classified at GMFCS levels I, II and III. Twenty-three normally developing children were used as controls [61 % boys, mean age 9.9 years (SD 2.6)]. Multiple linear regression analysis was performed.

Results

The mean GDI in the control group was 100 (SD 7.5). The mean GDI in the GMFCS level I group was 81 (SD 11), in the GMFCS level II group 71 (SD 11) and in the GMFCS level III group 60 (SD 9). Multiple linear regression analysis showed that gender, age and CP subclass had no significant correlation with the GDI, whereas height and weight had a slight impact.

Conclusion

This study showed a strong correlation between the GDI and GMFCS levels. The present data indicate that calculation of the GDI is a useful tool to characterise walking difficulties in children with spastic CP.

     

International Sleeve Gastrectomy Expert Panel Consensus Statement: best practice guidelines based on experience of >12,000 cases

BackgroundLaparoscopic sleeve gastrectomy (LSG) is an emerging surgical approach, but 1 that has seen a surge in popularity because of its perceived technical simplicity, feasibility, and good outcomes. An international expert panel was convened in Coral Gables, Florida on March 25 and 26, 2011, with the purpose of providing best practice guidelines through consensus regarding the performance of LSG. The panel comprised 24 centers and represented 11 countries, spanning all major regions of the world and all 6 populated continents, with a collective experience of >12,000 cases. It was thought prudent to hold an expert consensus meeting of some of the surgeons across the globe who have performed the largest volume of cases to discuss and provide consensus on the indications, contraindications, and procedural aspects of LSG. The panel undertook this consensus effort to help the surgical community improve the efficacy, lower the complication rates, and move toward adoption of standardized techniques and measures. The meeting took place at on-site meeting facilities, Biltmore Hotel, Coral Gables, Florida.MethodsExpert panelists were invited to participate according to their publications, knowledge and experience, and identification as surgeons who had performed >500 cases. The topics for consensus encompassed patient selection, contraindications, surgical technique, and the prevention and management of complications. The responses were calculated and defined as achieving consensus (≥70% agreement) or no consensus (<70% agreement).ResultsFull consensus was obtained for the essential aspects of the indications and contraindications, surgical technique, management, and prevention of complications. Consensus was achieved for 69 key questions.ConclusionThe present consensus report represents the best practice guidelines for the performance of LSG, with recommendations in the 3 aforementioned areas. This report and its findings support a first effort toward the standardization of techniques and adoption of working recommendations formulated according to expert experience.     

Characteristic imaging findings of tendinosis of the direct head of rectus femoris and their interpretation

BackgroundTendinosis at the origin of the direct head of rectus femoris causing anterior hip pain is termed AIISpinitis, but no study has investigated its imaging findings. The aim of the present study was to determine the characteristic imaging findings of AIISpinitis and clarify their pathological significance.MethodsWe reviewed the preoperative imaging findings of 62 hips in 58 patients who had undergone endoscopy with a diagnosis of AIISpinitis. The origin of the direct head of rectus femoris was evaluated by ultrasound (US) and magnetic resonance imaging (MRI), and the positive rate of abnormal findings and their agreement with endoscopy regarding injury of the direct head of rectus femoris were measured. Signal changes in the fat pad around the anterior inferior iliac spine (AIIS fat pad) in MRI were compared with the pathological findings of that harvested endoscopically.ResultsHypoechoic regions in US (53/62, 85%) and signal change in MRI (55/62, 89%) were observed with high frequency and corresponded with injury of the direct head of rectus femoris observed by endoscopy (58/62, 94%) (kappa coefficient, 0.43 [moderate agreement], 0.69 [good agreement] respectively). Hypoechoic regions had high sensitivity (85%) and specificity (86%) for AIISpinitis. Regarding the AIIS fat pad, punctate and completely hypo-intense change relative to normal fat corresponded to fibrosis and scar formation, respectively (weighted kappa coefficient, 0.51 [moderate agreement]).ConclusionsHypoechoic regions on US which had high sensitivity and specificity; and signal change at the origin of the direct head of rectus femoris and hypo-intensity of the AIIS fat pad on MRI were characteristic findings of tendinosis of the direct head of rectus femoris. These findings correspond pathologically to injury of the direct head of rectus femoris and fibrosis or scar formation in the AIIS fat pad, respectively.     

The utility of the delphi method in defining anastomotic leak following colorectal surgery

BackgroundAlmost a decade after international guidelines defining anastomotic leak (AL) were published, the definition of AL remains inconsistent.MethodsA 3-round modified Delphi study was conducted among a national panel of 8 surgeon experts to assess consensus related to the definition of AL following colorectal resection. Consensus was defined when a scenario was rated as very important or absolutely essential by at least 85% of the experts in round 3.ResultsSeven of fifteen (47%) clinical and radiological scenarios of AL achieved consensus. 80% of clinical scenarios reached consensus. 30% of radiological scenarios reached consensus including CT demonstrating air bubbles around the anastomosis. No consensus was achieved in 70% of radiological scenarios.ConclusionsConsensus on the definition of AL is difficult to reach, in relation to international guidelines; which implies that further refinement of the definition of AL is needed to compare patient outcomes.     

Results from a Canadian consensus forum of key controversial areas in the management of advanced prostate cancer: Recommendations for Canadian healthcare providers

IntroductionRapid progress in diagnostics and therapeutics for the management of prostate cancer (PCa) has created areas where high-level evidence to guide practice is lacking. The Genitourinary Research Consortium (GURC) conducted its second Canadian consensus forum to address areas of controversy in the management of PCa and provide recommendations to guide treatment.MethodsA panel of PCa specialists discussed topics related to the management of PCa. The core scientific committee finalized the design, questions, and analysis of the consensus results. Attendees then voted to indicate their management choice regarding each statement/topic. Questions for voting were adapted from the 2019 Advanced Prostate Cancer Consensus Conference. The thresholds for agreement were set at ≥75% for “consensus agreement,” >50% for “near-consensus,” and ≤50% for “no consensus.”ResultsThe panel was comprised of 29 PCa experts, including urologists (n=12), medical oncologists (n=12), and radiation oncologists (n=5). Voting took place for 65 predetermined questions and three ad hoc questions. Consensus was reached for 34 questions, spanning a variety of areas, including biochemical recurrence, treatment of metastatic castration-sensitive PCa, management of non-metastatic and metastatic castration-resistant PCa, bone health, and molecular profiling.ConclusionsThe consensus forum identified areas of consensus or near-consensus in more than half of the questions discussed. Areas of consensus typically aligned with available evidence, and areas of variability may indicate a lack of high-quality evidence and point to future opportunities for further research and education.     

Diagnostic evaluation, surgical technique, and perioperative management after esophagectomy: consensus statement of the German Advanced Surgical Treatment Study Group

Purpose

Correct diagnosis, surgical treatment, and perioperative management of patients with esophageal carcinoma remain crucial for prognosis within multimodal treatment procedures. This study aims to achieve a consensus regarding current management strategies in esophageal cancer by questioning a panel of experts from the German Advanced Surgical Treatment Study (GAST) group, comprised of 9 centers specialized in esophageal surgery, with a combined total of >220 esophagectomies per year.

Materials and methods

The Delphi method, a systematic and interactive, evidence-based approach, was used to obtain consensus statements from the GAST group regarding ambiguities and disparities in diagnosis, patient selection, surgical technique, and perioperative management of patients with esophageal carcinoma. After four rounds of surveys, agreement was measured by Likert scales and defined as full (100% agreement), near (??66.6% agreement), or no consensus (<66.6% agreement).

Results

Full or near consensus was obtained for essential aspects of esophageal cancer staging, proper surgical technique, perioperative management and indication for primary surgery, and neoadjuvant treatment or palliative treatment. No consensus was achieved regarding acceptability of minimally invasive technique and postoperative nutrition after esophagectomy.

Conclusion

The GAST consensus statement represents a position paper for treatment of patients with esophageal carcinoma which both contributes to the development of clinical treatment guidelines and outlines topics in need of further clinical studies.
