Patient perspectives of shared decision-making in emergency surgery.

Shared decision-making (SDM) is now considered the gold standard approach to counselling and obtaining patient consent. Research into patient perceptions of SDM is lacking and barriers to its implementation remain, specifically in the time-pressurized, high-risk emergency general surgery (EGS) setting. The aim of this work was to explore what EGS patients understand about SDM, gaining insight into their perspectives and experiences to understand the potential barriers both clinicians and patients may face. This work consisted of two parts: part 1 was an initial scoping review to inform the development of part 2-a patient and public involvement (PPI) exercise. The scoping review determined the quantity and quality of research in this area enabling long-listing of known SDM concepts. This long-list developed questions and structured discussions for the PPI exercise. Responses were transcribed, then analysed using thematic analysis. The scoping review found limited evidence for both the implementation of SDM in EGS and patients' perspectives. Seven papers considered SDM in other settings that allowed long-listing of the values and concepts for the PPI exercise. Nine patients and four supporters were identified from an established EGS database. After open discussion of the values and SDM concepts, thematic analysis was performed that identified two key themes: patient perceptions of how surgeons make decisions, and patient experiences of EGS decision-making. Five subtheme analyses showed participants were not aware of surgeons' use of '30-day mortality' and could not quantify surgical risk, feeling time pressures and out of control. Almost all relied on surgeons to make their decision, valuing the surgeon's opinion over their own. With no previous reported evidence, this work provides the first patient insights into SDM in the EGS setting. With multiple barriers identified, further work is essential to increase implementation of this gold standard approach to patient consent.

Comparison Between Surgical Techniques for Correction of Congenital Syndactyly: A Systematic Review and Meta Analysis.

This review aimed to assess which surgical technique has better outcomes to correct one of the most common congenital anomalies of the upper limb: syndactyly. The following databases were used in the search: PubMed, Embase, Cochrane (CENTRAL), LILACS, SciELO, Scopus and Web of Science, on October 27, 2022. Studies that described a surgical technique for correcting syndactyly and evaluated surgical complications were included. Studies about noncongenital or foot syndactyly were excluded. The risk of bias was assessed using a specific method for case reports. For synthesis of results, the characteristics of the studies and techniques were demonstrated by a qualitative analysis. Meta-analysis models were applied for complications, functionality, and aesthetic. 73 studies were included, of which 70 were series or case reports, 27 studies did not use skin grafts and 7 studies used external fixators. To evaluate functional results, 42 studies used only the surgeon's opinion. Meta-analyses showed a higher incidence of scar defects when using skin grafts and of infection when using external fixators. There was no difference for web creep and readmission. Few studies evaluated results using the VSS scale, showing worse scar pigmentation when skin grafts were used, but there was no difference in other parameters (PROSPERO CRD42022368930).

An Enigmatic Discovery - Accidental Insertion of Internal Jugular Haemodialysis Catheter into the Vertebral Vein

A 40-year-old male was admitted to the medical ward with chronic kidney disease with uremic symptoms and a decision was made to initiate the patient on haemodialysis. It was decided to catheterize the right internal jugular vein directly as the patient would require an A-V fistula in the near future which would be created in the left arm subsequently.
 Procedure
 During the time of right internal jugular vein catheterization using the anterior landmark technique, the right carotid artery was punctured leading to hematoma formation on the right side of the neck, despite adequate haemostatic measures.
 It was decided to catheterize the left internal jugular vein subsequently. Using the anterior landmark technique again, venipuncture was performed on the left side of the neck and in the first attempt itself the guide wire was inserted without any difficulty or resistance.
 Safe back-flow of venous blood was achieved through all ports of the catheter; that is, the catheter tip was presumed to be well positioned in the left internal jugular vein (IJV), as seen on the chest X-ray taken following the procedure.
 Clinical Course
 The patient complained of numbness over the left shoulder and weakness of the left upper limb following the procedure and was evaluated for the same. Under the clinical suspicion of left vertebral artery catheterization, a vascular surgeon opinion was sought and a CT angiogram of the neck was advised.
 The CT angiogram revealed the catheter entering the left vertebral vein at the level of C6 vertebra, coursing anteroinferiorly reaching the left brachiocephalic vein with its tip noted at the confluence of subclavian vein with internal jugular vein.
 After the CT angiogram, the misplaced catheter was promptly extracted to prevent the onset of additional complications.
 No excessive resistance was encountered during the catheter removal, and there were no signs of hematoma formation.
 Over the next few days, the patient’s symptoms of numbness and weakness resolved spontaneously.
 The patient had no neurological complaints and deficits on examination during follow-up in the outpatient department.

The impact of moderate versus deep neuromuscular blockade on the recovery characteristics following laparoscopic sleeve gastrectomy: A randomized double blind clinical trial.

Anesthesia with deep neuromuscular block for laparoscopic surgery may result in less postoperative pain with lower intra-abdominal pressure. However, the results in the existing literature are controversial. This study aimed to evaluate the effect of deep versus moderate neuromuscular block (NMB) on the postoperative recovery characteristics after laparoscopic sleeve gastrectomy (LSG) for weight loss surgery. This is parallel-group, randomized clinical trial. The study was conducted at a tertiary care center. Patients undergoing LSG were included. Patients were randomly assigned to either deep (post-tetanic count 1-2) or moderate (train-of-four 1-2) NMB group. The primary outcomes were numeric rating scale scores of the postoperative pain at rest and postoperative shoulder pain. The secondary outcomes were the length of hospital stay (LOS) and postoperative complications. The statistics were performed using StatsDirect statistical software (Version 2.7.9). Two groups were identified: Group D (deep NMB), 29 patients, and Group M (moderate NMB), 28 patients. The BMI mean values for groups D and M were 44 and 45 kg/m2 respectively (P > 0.05). The mean durations of surgery for were 46.7 min and 44.1 min for groups M and D, respectively (P > 0.05). The mean train-of-four (TOF) counts were 0.3 and 0 for groups M and D, respectively (P < 0.05). The mean times from giving reversal agent to tracheal extubation (minutes) were 6.5 and 6.58 min for groups M and D, respectively (P > 0.05). In the recovery room, the means of pain scores were 3 and 4 for groups M and D, respectively (P > 0.05). Upon admission to the surgical ward, the median values of the pain score were non-significant (P > 0.05) (95% CI: 0.4-0.7). The opioid consumption in the recovery room was non-significant between both groups (P > 0.05) (95% CI: 0.3-0.6). Postoperative shoulder pain was non-significant between both groups (P > 0.05) (95% CI: 0.4-0.7). The median values of surgeon opinion of both groups were non-significant (P > 0.05). Regarding the LOS, the mean values of groups D and M were 1.20 and 1.21 days, respectively (P > 0.05). There was no significant difference between moderate and deep NMB techniques in terms of duration of the surgical procedure, postoperative pain, shoulder pain, and length of hospital stay. Further studies on a larger sample size are required to investigate the long-term recovery characteristics of patients with obesity undergoing LSG.

The performance of large language models on fictional consult queries indicates favorable potential for AI-assisted vascular surgery consult handling

ObjectiveRecently, the use of large language models (LLMs) in medicine has become a prominent topic of discussion due to the rapid improvement of these tools in understanding and responding to natural language. Several models are widely available to the public, both proprietary and open-sourced. We aim to evaluate the possible use of such LLMs in vascular surgery by understanding their abilities to process common consult requests. MethodsThe senior author created 25 fictional vascular surgery consultation queries based on common consultation requests. Five attending surgeons and four LLMs (GPT 3.5, GPT 4, Bard, and Falcon 40B) were asked to answer whether each consult was an emergency that needed immediate attention within an hour. Responders were also asked whether the next best step was an examination, additional imaging, or an urgent operation. GPT 3.5 and 4 also provided free-response answers on the next best step, graded by attending surgeons based on scientific accuracy, possible harm, and content completeness. ResultsThe rates of accurate emergency identification were 88%, 100%, 76%, and 88% for GPT 3.5, GPT 4, Falcon 40B, and Bard, respectively. Although they have similar overall accuracy, GPT 3.5 has a high sensitivity at 100%, whereas Bard has a high specificity at 90%. GPT 4.0 had 100% sensitivity and specificity. LLMs agreed with the majority surgeon opinion on the next best step in 64% (GPT 3.5), 32% (GPT 4), 68% (Falcon 40B), and 36% (Bard) of cases. GPT 3.5 and 4 had a collective ratio of 89.5% of answers adhering to the scientific consensus. Only 5% of responses were highly likely to cause clinically significant harm. Although only 4% included incorrect content, 17.5% of answers missed important content. There was no significant difference between GPT 3.5 and 4 regarding the free-response grade. ConclusionsExisting, widely available LLMs exhibited a solid ability to identify vascular emergencies, with GPT 4.0 agreeing with surgeon attendings in 100% of cases. However, these models continue to have identifiable deficiencies in treatment recommendations, a higher-level task. Future models might help triage incoming consults and provide preliminary management suggestions. The utility of such tools in clinical practice remains to be explored.

Surgeon experience in second-look transurethral resection of bladder cancer – a prospective study

Introduction and objectivesTransurethral resection of bladder tumor (TURBT) is crucial in the treatment of bladder tumors and when incorrectly performed can cause staging mistakes. To avoid these errors, a second resection is recommended in selected cases. The aim of this study is to evaluate the surgeon's ability to predict histologically complete primary resection of newly diagnosed bladder tumors avoiding the need for a second TURBT. MethodsThis is a prospective, observational study involving 47 consecutive patients with newly diagnosed bladder tumors who had previously undergone primary TURBT, and met EAU criteria for second-look TURBT. Second-look TURBT specimens were analyzed for routine histological assessment and compared with the surgeon's impression of the tumor at initial resection. ResultsOf 91 patients submitted to primary TURBT, 47 met the criteria for second-look TURBT. Second-look specimens revealed residual disease in 20.9% of patients and 3 (6.4%) of patients showed upstaging disease. The sensitivity of a senior to detect disease on second-look TURBT in relation to muscle invasion was 75%, and the specificity was 85%. ConclusionsSecond-look TURBT is crucial in the treatment of bladder cancer and cannot be replaced by a surgeon's opinion, so international recommendations should be followed. Supervision of less experienced surgeons is a cornerstone.

The Brazilian Butt Lift Remains the Deadliest Aesthetic Surgery Procedure: Are Plastic Surgeons Adjusting Their Surgical Practice to Promote Safety?

The number of Brazilian butt lift (BBL) fatalities remains high in the United States despite numerous practice advisories geared towards patient safety and reducing the incidence of fatal pulmonary fat emboli. This study aimed to evaluate US board-certified plastic surgeons' opinions, understanding of BBL-related mortality, and current risk-reducing surgical practices for BBL procedures. An online 18-question survey was distributed via email by the Aesthetic Surgery Education and Research Foundation to national board-certified plastic surgeon members of the The Aesthetic Society. Survey responses were collected over 21 days on the Qualtrics platform. The survey response rate was 10% (n = 178). Of the 77% who performed BBL procedures, 48% (n = 80) did not use ultrasound. Approximately 60% (n = 102) of all respondents disagreed with imposing regulations to require ultrasound, with the most frequent reason being that it was unnecessary with adequate surgeon experience (45%). Plastic surgeons thought that high-volume budget clinics (n = 64) and a lack of regulations imposed on individual surgeons by boards of medicine (n = 31) were the greatest contributors to BBL mortality. Most US plastic surgeons did not use ultrasound for BBL procedures and did not agree that ultrasound should be required, which may partially be the result of unsuccessful educational outreach for risk-reducing practices and training for ultrasound. Regulations by the boards of medicine imposed on individual surgeons, in combination with new legislation targeted at ownership of high-volume clinics, are strongly backed by surgeon respondents as measures that may improve patient safety.

Global Surgeon Opinion on the Impact of Surgical Access When Using Endocutters Across Specialties

Background: Despite design enhancements in endocutters, key challenges related to limited surgical access and space can impact stapling and, potentially, surgical outcomes. Objectives: This study aimed to develop consensus statements outlining the clinical value of precise articulation and greater anatomical access in minimally invasive surgery performed by bariatric, colorectal, and thoracic surgeons. Methods: Colorectal, bariatric, and thoracic surgeons from Japan, the United States, United Kingdom, and France participated in a 2-round modified Delphi panel. Round 1 included binary, Likert scale–type, multiple-response, and open-ended questions. These were converted to affirmative statements for round 2 if sufficient agreement was reached. Consensus was set at a predefined threshold of at least 90% of panelists across all surgical specialties and regions selecting the same option (“agree” or “disagree”) for the affirmative statements. Results: Of the 49 statements in the round 2 questionnaire, panelists (n=135) reached consensus that (1) tissue slippage outside stapler jaws can occur due to limited access and space; (2) greater jaw aperture could help to manipulate thick or fragile tissue more easily; (3) articulation of an endocutter is clinically important in laparoscopic surgeries; (4) improved access to hard-to-reach targets and in limited space would improve safety; and (5) an endocutter with improved access through greater articulation would become common use. Discussion: By understanding user-specific challenges and needs from both specialty- and region-wide perspectives, endoscopic stapling devices can continue to be refined. In this study, improved articulation and greater jaw aperture were the key design features examined. Improved articulation and greater jaw aperture were key stapler design features identified in this study that may mitigate the risk of instrument clashes and intraoperative complications such as anastomotic leaks. Conclusions: This study gained insights into surgeons’ perspective across a variety of specialties and from 3 distinct geographies. Participating surgeons reached consensus that an endocutter with greater jaw aperture and articulation may improve surgical access and has potential to improve surgical outcomes.

An Intrauterine Complete Perineal Tear in a Female Neonate, A Rare Birth Injury Related to Breech Presentation: A Case Report

Birth injuries are wounds that a newborn receives when being delivered, whether vaginally or via lower segment caesarean section. It is a case of a 39-week pregnant female with foetal distress and breech presentation in labour who was received in the emergency labour room as a referral case after multiple per vaginal examinations done by a staff nurse at a peripheral hospital, with a complaint of leaking and bleeding per vaginum since then. Her emergency LSCS was done in view of foetal distress with breech presentation. A female baby was extracted and found to have a complete perineal tear in an otherwise healthy neonate. Her paediatric surgeon's opinion wassought, and a complete perineal tear was done in layers with Vicryl 3-0 sutures. On follow-up, the female neonate was continent and thriving well. Unintended vaginal examinations during breech presentation could result in an intrauterine complete perineal tear if the examiner is untrained. If these injuries are identified immediately and prompt management is done, it may lead to lesser morbidity and a better quality of life.

Results of the ARROW survey of anti-reflux practice in the United Kingdom.

Gastro-esophageal reflux disease (GERD) is a common, significant health burden. United Kingdom guidance states that surgery should be considered for patients with a diagnosis of GERD not suitable for long-term acid suppression. There is no consensus on many aspects of patient pathways and optimal surgical technique, and an absence of information on how patients are currently selected for surgery. Further detail on the delivery of anti-reflux surgery (ARS) is required. A United Kingdom-wide survey was designed to gather surgeon opinion regarding pre-, peri- and post-operative practice of ARS. Responses were received from 155 surgeons at 57 institutions. Most agreed that endoscopy (99%), 24-hour pH monitoring (83%) and esophageal manometry (83%) were essential investigations prior to surgery. Of 57 units, 30 (53%) had access to a multidisciplinary team to discuss cases; case-loads were higher in those units (median 50 vs. 30, P < 0.024). The most popular form of fundoplication was a Nissen posterior 360° (75% of surgeons), followed by a posterior 270° Toupet (48%). Only seven surgeons stated they had no upper limit of body mass index prior to surgery. A total of 46% of respondents maintain a database of their practice and less than a fifth routinely record quality of life scores before (19%) or after (14%) surgery. While there are areas of consensus, a lack of evidence to support workup, intervention and outcome evaluation is reflected in the variability of practice. ARS patients are not receiving the same level of evidence-based care as other patient groups.

Training and Credentialing Standards for Minimally Invasive Spinal Surgery Techniques: Results of a Survey

BACKGROUND: The controversy continues on how to best become proficient in contemporary minimally invasive spinal surgery techniques (MISST). Postgraduate training programs typically lag behind the innovation. Other subspecialty spine care providers often compete with spine surgeons particularly when they do not offer the treatments needed by their patients. The public debate centers around who should be taught and credentialed in providing surgical spine care. OBJECTIVES: The purpose of this study was to conduct an opinion survey amongst spine care providers regarding the learning curve of MISST and which credentialing standards should be established. SETTING: Surgeon online opinion survey sent by email, and chat groups in social media networks, including WeChat, WhatsApp, and LinkedIn. METHODS: Surgeons were asked the following questions: 1) Do you think MISS is harder to learn compared to open surgery? 2) Do you perform MISS? 3) What type of MISS do you perform? 4) If you perform endoscopic surgery, which approach(es)/technique(s) do you employ? 5) In your opinion, where does the innovation take place? 6) Where should MISST be taught? 7) Do you think mastering the MISST learning curve and surgeon skill level affect patient outcomes? 8) Which credentialing criteria do you recommend? Demographic data of responding surgeons, including age, postgraduate training and years from graduation, and practice setting, were also obtained. Descriptive statistics were employed to count the responses and compared to the surgeon’s training using statistical package SPSS Version 27.0 (IBM Corporation, Armonk, NY). RESULTS: The online survey was viewed by 806 surgeons, started by 487, and completed by 272, yielding a completion rate of 55.9%. Orthopedic surgeons comprised 52.6% (143/272) of respondents, followed by 46.7% (127/272) neurosurgeons, and 0.7% pain management physicians (2/272). On average, respondents had graduated from a postgraduate training program 15.43 ± 10.13 years. Nearly all respondents employed MISST (252/272; 92.8%) and thought that proficiency in MISST affects patients’ outcomes (270/272; 98.2%). Some 54.1% (146/270) opined that MISS is more challenging to learn than traditional open spine surgery. Preferred credentialing criteria were 1) number of MISST cases (87.5%; 238/272), b) skill level (69.9%; 190/272), and c) proficiency assessment (59.9%; 163/272). A case log review (42.3%; 116/272) or an oral examination (26.1%; 71/272) was not favored by surgeons. Surgeons reported academia (43.4%; 116/267) and private practice (41.2%; 110/267) as the centers of innovation. Only 15.4% (41/267) of respondents opined that industry was the main driver over innovation. LIMITATIONS: Geographical and cultural biases may impact the opinions of responding surgeons. CONCLUSIONS: Respondents preferred case volume, skill level, and proficiency assessment as credentialing criteria. Surgeons expect academic university programs and specialty societies to provide the necessary training in novel MISST while working with governing boards to update the certification programs. KEY WORDS: Surgeon opinion survey, minimally invasive spinal surgery, learning curve, credentialing, teaching standards

Parathyroid Autofluorescence in Pediatric Thyroid Surgery: Experience With False Positive and False Negative Results.

Devices for near-infrared light stimulation of autofluorescence (NIRAF) allow for intraoperative identification of parathyroid glands with high sensitivity in adults. However, their performance in the pediatric population is unknown. In this case series with chart review at a tertiary academic children's hospital, we investigated pediatric patients undergoing thyroid surgery and concurrent use of a probe-based NIRAF device. Thirteen patients (ages 6-18 years) underwent thyroid and/or neck dissection procedures, and 2 patients had revision procedures for a total of 15 cases with the NIRAF device. Eight cases had NIRAF values that matched surgeon opinion of parathyroid tissue or histology when available. Six cases had false positive NIRAF readings (40.0%) and 1 case had false negative readings (6.7%). Compared with surgeon opinion or histology, the NIRAF device confirmed 26 of 34 parathyroid gland candidates (76.5%). These devices need further investigation in pediatric patients, whose tissues may have different autofluorescence characteristics.

Spectrum, Procedural Feasibility, and the Value of a Surgeon's Opinion in Varying Gender-Affirming Surgeries.

The understanding of gender has expanded contributing to gaps in gender-affirming care. Traditional gender-affirming surgeries focus on binary results, diminishing room for affirmation of other identities. Surgeons are faced with the challenge of deciding whether a variation of gender-affirming surgery can be safely performed per request. The ethical question of when a surgeon may say yes or no to these varying requests comes after the consideration of premorbid conditions, body habitus, age, social and family support, individuals' goals, and risk assessment. Preoperative evaluations must take into account surgical experience, barriers to care, increased risk profile, and the surgeon's personal biases.

Thoracolumbar Injury: The Thoracolumbar Injury Classification and Severity Scoring System or Modified Thoracolumbar Injury Classification and Severity?

To compare the Thoracolumbar Injury Classification and Severity (TLICS) scoring system with its modified (mTLICS) version based on their agreement with the surgeon's opinion regarding treatment for patients with thoracolumbar injuries. Moreover, the Posterior Ligamentous Complex health was compared between intraoperative examinations and magnetic resonance imaging (MRI) reports. MRI was obtained from 114 patients suffering thoracolumbar spinal trauma; the TLICS and mTLICS scores were measured. Approaches 1 and 2 were designed in both scoring systems based on assuming a total score of 4 as surgery and conservative management indication, respectively. Kappa was used to estimate the agreements between each approach and the surgeon's opinion on treatment. The receiver operating curve calculated the appropriate cut-off scores for the above systems over which surgical management was preferred. A P < 0.05 was considered significant. All the approaches showed moderate agreements with the surgeon's opinion on therapeutic management (TLICS: κapproach1=0.557, κapproach2=0.508; mTLICS: κapproach1=0.557, κapproach2=0.551; P < 0.001 for each κ). A score >3.5 best illustrated the indication for surgery in both systems. The radiology report agreed stronger with intraoperatively observed ligamentous health when suspicious cases on MRI were reported as injured (κTLICS= 0.830, κmTLICS= 0.704) rather than healthy (κTLICS= 0.620, κmTLICS= 0.620). The surgeon's treatment plan agreed moderately with suggestions of the TLICS and mTLICS systems; surgery was the preferred management for the patients with a score of 4. Moreover, radiologic suspicion of Posterior Ligamentous Complex injury seemed to indicate a damaged ligament rather than a healthy one.

Radiological malunion after ankle fractures in older adults : definitions and new thresholds derived from clinical outcome data from the AIM trial.

The rationale for exacting restoration of skeletal anatomy after unstable ankle fracture is to improve outcomes by reducing complications from malunion; however, current definitions of malunion lack confirmatory clinical evidence. Radiological (absolute radiological measurements aided by computer software) and clinical (clinical interpretation of radiographs) definitions of malunion were compared within the Ankle Injury Management (AIM) trial cohort, including people aged ≥ 60 years with an unstable ankle fracture. Linear regressions were used to explore the relationship between radiological malunion (RM) at six months and changes in function at three years. Function was assessed with the Olerud-Molander Ankle Score (OMAS), with a minimal clinically important difference set as six points, as per the AIM trial. Piecewise linear models were used to investigate new radiological thresholds which better explain symptom impact on ankle function. Previously described measures of RM and surgeon opinion of clinically significant malunion (CSM) were shown to be related but with important differences. CSM was more strongly related to outcome (-13.9 points on the OMAS; 95% confidence interval (CI) -21.9 to -5.4) than RM (-5.5 points; 95% CI -9.8 to -1.2). Existing malunion thresholds for talar tilt and tibiofibular clear space were shown to be slightly conservative; new thresholds which better explain function were identified (talar tilt > 2.4°; tibiofibular clear space > 6 mm). Based on this new definition the presence of RM had an impact on function, which was statistically significant, but the clinical significance was uncertain (-9.1 points; 95% CI -13.8 to -4.4). In subsequent analysis, RM of a posterior malleolar fracture was shown to have a statistically significant impact on OMAS change scores, but the clinical significance was uncertain (-11.6 points; 95% CI -21.9 to -0.6). These results provide clinical evidence which supports the previously accepted definitions. Further research to investigate more conservative clinical thresholds for malunion is indicated.Cite this article: Bone Jt Open2022;3(10):841-849.

Repairing small type I hiatal hernias at the time of RYGB is not necessary to achieve resolution of reflux symptoms.

Roux-en-Y gastric bypass (RYGB) is the gold standard operation for gastroesophageal reflux disease (GERD) in patients with severe obesity, but there is variability in surgeon opinion regarding whether small type I hiatal hernias (HH) require routine repair concurrently with RYGB. We sought to examine whether leaving small type I HHs unrepaired during RYGB affected GERD outcomes. Pre-operatively our patients all receive endoscopy, and select patients with reflux symptoms receive esophagram based on attending surgeon practice and preference. We routinely repair paraesophageal hernias (PEH) concurrently with RYGB, but refrain from repairing small type I HH if, intra-operatively, the gastric fat pad and cardia are below the diaphragm with no evidence of retraction into the mediastinum. Records from 268 consecutive patients undergoing primary RYGB between January 2016 and February 2021 who completed pre-operative GERD-HRQL assessments were reviewed for presence of type I HH or PEH. Mann-Whitney U tests examined the pre-operative to post-operative change in GERD-HRQL in patients with type I HH left unrepaired at the time of RYGB (HH group) and patients with no hernia (NH group). Pre-operatively, GERD-HRQL scores were not statistically different between HH group (median = 7, mean = 8.5, n = 100) and NH group (median = 6.5, mean = 7.2, n = 141) (p > 0.05). Post-operatively, there was no increase in GERD-HRQL scores patients whose hernias were left unrepaired. Neither group had clinically pathologic post-operative GERD-HRQL scores, with median 6months scores of 1 for HH group (n = 68) versus 1.5 for NH group (n = 90) (p > 0.05), and median 12months scores of 1.5 for HH group (n = 40) versus 1 for NH group (n = 56) (p > 0.05). Repair of small type I HH is not necessary to achieve effective, durable resolution of reflux symptoms with RYGB. Omitting repair reduces operative time, cost, and potential risk without adverse impact on post-operative reflux symptoms.

Anterior distal femoral hemiepiphysiodesis in children with cerebral palsy: Establishing surgical indications and techniques using the modified Delphi method and literature review.

Purpose:The purpose of this study was to develop consensus for the surgical indications of anterior distal femur hemiepiphysiodesis in children with cerebral palsy using expert surgeon opinion through a modified Delphi technique.Methods:The panel used a 5-level Likert-type scale to record agreement or disagreement with 27 statements regarding anterior distal femur hemiepiphysiodesis. Consensus was defined as at least 80% of responses being in the highest or lowest 2 of the Likert-type ratings. General agreement was defined as 60%–79% falling into the highest or lowest 2 ratings.Results:For anterior distal femur hemiepiphysiodesis, 27 statements were surveyed: consensus or general agreement among the panelists was achieved for 22 of 27 statements (22/27, 82%) and 5 statements had no agreement (5/27, 18%). There was general consensus that anterior distal femur hemiepiphysiodesis is indicated for ambulatory children with cerebral palsy, with at least 2 years growth remaining, and smaller (<30 degrees) knee flexion contractures and for minimally ambulatory children to aid in standing/transfers. Consensus was achieved regarding the importance of close radiographic follow-up after screw insertion to identify or prevent secondary deformity. There was general agreement that percutaneous screws are preferred over anterior plates due to the pain and irritation associated with plates. Finally, it was agreed that anterior distal femur hemiepiphysiodesis was not indicated in the absence of a knee flexion contracture.Conclusion:Anterior distal femur hemiepiphysiodesis can be used to treat fixed knee flexion contractures in the setting of crouch gait, but other associated lever arm dysfunctions must be addressed by single-event multilevel surgery.Level of evidence:V
