Why knees fail in 2011: patient, surgeon, or device?

The outcome of total knee arthroplasty (TKA) is influenced by multiple interconnected factors, including patient selection, implant design, and surgical technique. Total knee arthroplasty has been shown to be highly successful, with patient satisfaction rates reported from 85% to 95% with low rates of failure, but if failure occurs, its impact is significant. In 2003, 402,000 primary TKAs and 32,000 revision TKAs were performed in the United States, and the number of TKAs is expected to double by 2015. Recent data on modern implant designs and techniques have demonstrated a surprising number of early failures, although the true number of early failures is unknown. Patient medical comorbidities should be optimized preoperatively, while psychosocial issues and workers compensation are more nebulous yet contribute greatly to patient perceived outcomes. Understanding current failure mechanisms of primary TKA and how to prevent complications will be critical to help manage a potentially overwhelming TKA revision burden. This article discusses failure rates as well as factors from the patient, surgeon, and device, that contribute to TKA failure.     

The treatment of segmental tibial fractures: does patient preference differ from surgeon choice?

IntroductionSegmental tibial fractures are complex injuries with a prolonged recovery time. Current definitive treatment options include intramedullary fixation or a circular external fixator. However, there is uncertainty as to which surgical option is preferable and there are no sufficiently rigorous multi-centre trials that have answered this question. The objective of this study was to determine whether patient and surgeon opinion was permissive for a randomised controlled trial (RCT) comparing intramedullary nailing to the application of a circular external fixator.Materials and methodsA convenience questionnaire survey of attending surgeons was conducted during the United Kingdom’s Orthopaedic Trauma Society annual meeting 2017 to determine the treatment modalities used for a segmental tibial fracture (n = 63). Patient opinion was obtained from clinical patients who had been treated for a segmental tibial fracture as part of a patient and public involvement focus group with questions covering the domains of surgical preference, treatment expectations, outcome, the consent process and follow-up regime (n = 5).ResultsBased on the surgeon survey, 39% routinely use circular frame fixation following segmental tibial fracture compared to 61% who use nail fixation. Nail fixation was reported as the treatment of choice for a closed injury in a healthy patient in 81% of surgeons, and by 86% for a patient with a closed fracture who was obese. Twenty-one percent reported that they would use a nail for an open segmental tibia fracture in diabetics who smoked, whilst 57% would opt for a nail for a closed injury with compartment syndrome, and only 27% would use a nail for an open segmental injury in a young fit sports person. The patient and public preference exercise identified that sleep, early functional outcomes and psychosocial measures of outcomes are important.ConclusionWe concluded that a RCT comparing definitive fixation with an intramedullary nail and a circular external fixator is justified as there remains uncertainty on the optimal surgical management for segmental tibial fractures. Furthermore, psychosocial factors and early post-operative outcomes should be reported as core outcome measures as part of such a trial.     

Immediate breast reconstruction: who is more satisfied,the surgeon or the patient?

The aim of this study is to evaluate the results of immediate breast reconstruction from the viewpoint of both the surgeon and the patient. Between 1993 and 2001, 122 patients underwent immediate breast reconstruction. The morphological results were evaluated by the surgical team based on visuals. The patients responded to a questionnaire (77 answers, mean follow up 4.7 years). Both groups gave ratings from 0 to 10. The ratings were compared between the two groups surgeon/patients and according to the mastectomy techniques (Patey versus skin sparing mastectomy) and to the reconstruction techniques (prosthesis versus autologous flaps). There was a difference in the evaluation of the surgeons and the patients; surgeons preferred flaps while the patients favoured a simple technique with prosthesis.Presented at the 14^th Annual Meeting of the European Association of Plastic Surgeons (EURAPS), Vienna, Austria, May 29–31, 2003     

When should a cardiologist refer a patient with aortic valve disease to a surgeon?

In general, aortic stenosis and regurgitation are the 2 main aortic valve diseases which require surgical treatment. Surgical indication for each has been described in detail in the guidelines established by the Japanese Circulation Society and American Heart Association/American College of Cardiology (AHA/ACC). Most of the cases we daily encounter in clinical practice can be managed within the guideline, although the patient's many other factors are needed to be taken into consideration. On the contrary, in those cases with the conditions which are not mentioned in the guidelines, diagnosis and decisions are always difficult to make. In this article, we are to discuss how to manage cases within and without the guidelines.     

Discordance between the patient’s and surgeon’s perception of complications following hernia surgery

Background: The study was undertaken in order to assess the degree of concordance between the patients and surgeons perceptions of adverse events after groin hernia surgery.Methods: 206 patients who underwent elective surgery for groin hernia at Samariterhemmet, Uppsala, Sweden in 2003 were invited to a follow-up visit after 3–6 weeks. At this visit the patient was instructed to answer a questionnaire including 12 questions concerning postoperative complications. A postoperative history was taken and a clinical examination performed by a surgeon who was not present at the operation and did not know the outcome of the questionnaire. All complications noted by the physician were recorded for corresponding questions in the questionnaire.Results: 174 (84.5%) patients attended the follow up, 161 men and 13 women. A total of 190 complications were revealed by the questionnaire, 32 of which had caused the patient to seek help from the health-care system. There were 131 complications registered as a result of the follow-up clinical examinations and history. Kappa levels ranged from 0.11 for urinary complications to 0.56 for constipation.Conclusion: In general, the concordance was poor. These results emphasise the importance of providing detailed information about the usual postoperative course prior to the operation. Whereas the surgeon, from a professional point of view, has a better idea about what should be expected in the postoperative period and how any complications should be categorised, only the patient has a complete picture of the symptoms and adverse events. This makes it impossible to reach complete agreement between the patients and surgeons perceptions of complications, even under the most ideal circumstances.     

Counseling in urogynecology: A difficult task,or simply good surgeon–patient communication?

Surgical treatments for pelvic organ prolapse (POP) and urinary incontinence (UI) have greatly changed in recent years. Prompted by increases in reports of adverse outcomes in relation to such treatments, several scientific societies and researchers have emphasized providing patients with thorough counseling before treating them. Patient-centered communication has become the gold standard for excellence in clinical care. This challenges clinicians to be cognizant of their patients’ perspectives, motivations, expectations, fears, concerns, and social contexts to enable them to reach a shared understanding with patients. Considering this, urogynecology counseling represents a crucial process through which women can gain a clear understanding of their clinical condition and the risks and benefits of potential treatment options. However, many urogynecologists believe that proposing a treatment and providing only enough detail to secure informed consent constitutes counseling. This article is intended to describe good counseling for women undergoing urogynecological surgery and to suggest optimal methodologies for implementation.     

Airway obstruction during arthroscopic shoulder surgery: anesthesia for the patient or for the surgeon?

Two cases of airway obstruction as a result of oedema of laryngeal structures which arose during protracted arthroscopic shoulder surgery, in which single-shot interscalene blocks had been performed, are reported. In these 2 cases, the complexity of the pathologies and the fact that the surgeons were at the beginning of their surgical experience are the most likely causes of the conditions which led to tracheal compression from extra-articular leakage of fluid. Therefore, we recommend a combined peripheral block and general anaesthesia with tracheal intubation for procedures performed by surgeons without an adequate experience and on obese patients, patients placed in a lateral decubitus, or procedures in which difficulties are expected. The advantages of regional anaesthesia with a constant control of the airways are underlined.     

The AESOP robot system in laparoscopic surgery: Increased risk or advantage for surgeon and patient?

Background The aim of this study was to examine the advantages and risks of the Automated Endoscopic System for Optical Positioning (AESOP) 3000 robot system during uncomplicated laparoscopic cholecystectomies or laparoscopic hernioplasty.Methods In a randomized study, we examined two groups of 120 patients each with the diagnosis cholecystolithiasis respectively the unilateral inguinal hernia. We worked with the AESOP 3000, a robotic arm system that is voice-controlled by the surgeon. The subjective and objective comfort of the surgeon as well as the course and length of the operation were measured.Results The robot-assisted operations required significantly longer preparation and operation times. With regard to the necessary commands and manual camera corrections, the assistant group was favored. The same was true for the subjective evaluation of the surgical course by the surgeon.Conclusions Our study showed that the use of AESOP during laparoscopic cholecystectomy and hernioplasty is possible in 94% of all cases. The surgeon must accept a definite loss of comfort as well as a certain loss of time against the advantage of saving on personnel.     

Comparison between patient and surgeon perception of degenerative spine disease outcomes—a prospective blinded database study

Background

Few have studied the correlation between patients’ and spine surgeons’ perception on outcomes, or compared these with patient-reported outcome scores. Outcomes studies are increasingly important in evaluating costs and benefits to patients and surgeons, and in developing metrics for payer evaluation and health care policy-making.

Objective

To compare patients’ and surgeons’ assessment of spine treatment outcome in a prospective blinded patient-driven spine surgery outcomes registry, and to correlate perceived outcomes ratings to validated outcomes scores.

Methods

Patients filled out surveys at baseline, 3 months and 6 months postoperatively, including Visual Analog Scale (VAS), and Neck Disability Index (NDI) or Oswestry Disability Index (ODI). Outcome was rated independently by patients and surgeons on a 7-point Likert-type scale.

Results

Two-hundred and sixty-five consecutive adult patients were surgical candidates. Of these, 154 (58.1 %) opted for surgery, with 69 (44.8 %) cervical and 85 (55.2 %) lumbar patients. One hundred and thirty-five (87.7 %) had both patient and surgeon postoperative ratings. Surgeons’ and patients’ ratings correlated strongly (Spearman rho?=?0.53, p?<?0.0001, 45.9 % identical, 88.2 % +/? 1 grade). The surgeon rated outcomes were better than patients in 29.8 % and worse in 21.15 %. Patient rating correlated better with the most recent NDI/ODI and pain scores than with incremental change from baseline. In multivariate analysis, age, location (cervical vs lumbar), pain ratings, and functional scores (NDI, ODI) did not have significant impact on the discrepancy between patient and surgeon ratings.

Conclusions

Patients’ and surgeons’ global outcome ratings for spinal disease correlate highly. Patients’ ratings correlate better with most recent functional scores, rather than incremental change from baseline.     

How does the participation of a resident surgeon in procedures for small intracranial aneurysms impact patient outcome?

OBJECT: In this paper the authors' goal was to evaluate whether resident neurosurgeons participating in entry-level aneurysm surgery have a negative impact on patient outcomes. METHODS: The authors searched the database for entry-level aneurysm surgeries (that is, those < or =10 mm and located in the internal carotid artery [beyond the paraclinoid segment] and middle cerebral artery) performed in 1991 through 2005. The presence or absence of an advanced resident (in his/her last 3 years of residency) was noted. The analysis was examined in 3-year quintiles. A total of 355 cases (196 with resident participation and 159 without) were evaluated. Permanent adverse outcomes were seen in 11 patients (3.1% of the total study population), all due to branch artery occlusion. The incidence of permanent adverse outcomes in the first 3 years was 10.7% and 2.4% thereafter. This difference was statistically significant (p = 0.015). There was no difference in the incidence of adverse outcomes when comparing surgery performed with and without participation of an advanced resident. CONCLUSIONS: In this study the authors have demonstrated a learning curve in this series of patients. This study also suggests that involving residents in the repair of small unruptured aneurysms will not compromise patient care. In addition, patients can be informed that the team approach to their surgery is at least as good as having the experienced surgeon performing all aspects of the surgery.     

Air leaks following pulmonary resection for lung cancer: is it a patient or surgeon related problem?

INTRODUCTION

Prolonged air leak (PAL) is the most common complication after partial lung resection and the most important determinant of length of hospital stay for patients post-operatively. The aim of this study was to determine the risk factors involved in developing air leaks and the consequences of PAL.

METHODS

All patients undergoing lung resection between January 2002 and December 2007 in our hospital were studied retrospectively. Univariate analysis to predict risk factors for developing post-operative air leaks included patient demographics, smoking status, pulmonary function tests, disease aetiology (benign, malignant), neoadjuvant therapy (pre-operative radiotherapy/chemotherapy), extent and type of resection, and different consultant surgeons’ practice. A logistic regression model was used for multivariate analysis.

RESULTS

A total of 1,911 lung resections were performed over the 6-year study period. An air leak lasting more than 6 days post-operatively was present in 129 patients (6.7%). This included 100 out of the 1,250 patients (8%) from the lobectomy group and 29 out of the 661 patients (4.4%) from the wedge/segmentectomy group. Using the multivariate analysis, the risk factors for developing an air leak included a low predicted forced expiratory volume in 1 second (pFEV₁) (p<0.001), performing an upper lobectomy (p=0.002) and different consultant practice (p=0.02). PAL was associated with increased length of stay (p<0.0001), in-hospital mortality (p=0.003) and intensive care unit readmission (p=0.05).

CONCLUSIONS

Air leaks after pulmonary resections were at an acceptable rate in our series. Particular patients are at a higher risk but meticulous surgical technique is vital in reducing their incidence. Our study shows that pFEV₁is the strongest predictor of post-operative air leaks.     

Rise of the wound surgeon to academic surgeon: myth or historical fact?

In contrast to modern academic surgery, in 19th century German medical care was mainly taken by non-academic barber surgeons. Only after the foundation of the German Reich (1871) the practice of surgery was made conditional on a full study of medicine. The present article follows up the moot question whether the last generation of barber surgeons succeeded in rising to academic status or if the strong tradition of surgery in barber families was brought to a complete standstill. By evaluating archival documents it can be clearly shown that the professional distance between barber surgery and academic medicine was not invincible. A considerable number of barbers and their descendents (subsequently) succeeded in studying medicine and starting a medical career.     

Short-term outcomes and one surgeon’s learning curve for thoracoscopic esophagectomy performed with the patient in the prone position

Purpose

Thoracoscopic esophagectomy with the patient in the prone position (TEP) is now being performed as minimally invasive esophagectomy for esophageal cancer. This study examines the short-term outcomes and the learning curve associated with TEP.

Methods

One surgeon (“Surgeon A”) performed TEP on 100 consecutive patients assigned to three periods based on treatment order. Each group consisted of 33 or 34 patients. The outcomes of the three groups were compared to define the influence of surgeon expertise.

Results

Outcomes improved as Surgeon A gained experience in performing this operation, as evidenced by reduced thoracic operative times between periods 1 and 2, and then between periods 2 and 3 (p = 0.0033 and p = 0.0326, respectively); an increased number of retrieved chest nodes between periods 1 and 2 (p = 0.0070); and a decline in recurrent laryngeal nerve (RLN) palsy between periods 2 and 3 (p = 0.0450). Period 2 was the pivotal period for each learning curve.

Conclusions

An individual surgeon’s learning curve over the course of 100 TEP procedures had three outcomes: a shortened operative time, a higher number of retrieved chest nodes, and a decreased rate of RLN palsy. Approximately 30–60 cases were needed to reach a plateau in the TEP procedure and a reduction in the morbidity rate.
