  1. Benefits of Bariatric Surgery and Perioperative Surgical Safety

    Ji Chung Tham


    Full Text Available Obesity is a worldwide problem with numerous associated health problems. The number of patients eligible for surgery outnumber surgical capacity and so patients need to be prioritised based on their obesity- related health burden and comorbidities. Weight loss as a result of bariatric surgery is significant and maintained in the long term. In addition to weight loss, patient health improves in terms of metabolic, macrovascular, and microvascular disease. As a result, quality of life is better, along with psychosocial wellbeing. Bariatric surgery is associated with a relatively low number of complications and appears to result in a reduction in mortality risk due to the resolution of comorbidities. Hence, surgery can now be routinely considered as an adjunct to medical therapy in the management of obesity.

  2. [Dealing with surgical complications after bariatric gastric bypass surgery].

    Schlesinger, Nis Hallundbæk; Naver, Lars


    The subject of this article is surgical complications to Roux-en-Y-gastric bypass and how to deal with them. The article addresses doctors, who are on duty in hospitals without bariatric surgery and who often deal with this patient category in the acute situation. Managing complications is challenging due to both the patient's physiognomy and the wide-ranged change in anatomy. The article gives a review of the literature and hands-on-recommendations for treating anastomotic leak, post-operative bleeding, internal herniation, bowel obstruction and biliary complications.

    Full Text Available Scott S Um1, Wendelin Slusser2, Daniel A DeUgarte11Department of Surgery, David Geffen School of Medicine at UCLA, Los Angeles, CA, USA; 2Department of Pediatrics, David Geffen School of Medicine at UCLA, Los Angeles, CA, USAAbstract: Adolescent obesity is a growing health concern that can have immense physical and psychological impact. Treatment of morbidly obese adolescents should include a multidisciplinary team to address medical comorbidities, diet, physical activity, mental health, and behavior modification. Anti-obesity pharmacologic agents have a limited role in the treatment of adolescents because of concerns with side effects, safety, and efficacy. Orlistat (GlaxoSmithKline, Moon Township, PA is the only approved medication for weight-loss in adolescents. However, it is associated with gastrointestinal side effects and its long-term efficacy is unknown. Bariatric surgery is the most effective therapy to treat morbid obesity. However, adolescents must meet rigorous criteria and have appropriate cognitive, psychological, and social clearance before being considered for surgical intervention. Gastric bypass remains the gold standard bariatric operation. The adjustable gastric band is not FDA-approved for use in patients under 18 years of age. Sleeve gastrectomy is a promising procedure for adolescents because it avoids an intestinal bypass and the implantation of a foreign body. Prospective longitudinal assessment of bariatric surgery procedures is required to determine long-term outcomes. In this manuscript, we review the treatment options, efficacy, and impact on quality of life for morbidly obese adolescents.Keywords: bariatric surgery, morbid obesity, weight loss, adolescent

  5. Bariatric Surgery in Youth.

    Mirensky, Tamar L


    Bariatric surgery provides a clinically effective and cost-effective means of achieving sustained weight reduction and management of associated comorbidities and has been met with increasing enthusiasm for application in obese youth. Following trends seen among obese adults, carefully selected obese youth are now undergoing bariatric surgical procedures with excellent short-term and intermediate-term outcomes. Although long-term data are not yet available, the results thus far hold great promise in the management of this population. PMID:27241972

  6. Mental and Physical Impact of Body Contouring Procedures on Post–Bariatric Surgery Patients

    Singh, Devinder; Zahiri, Hamid R.; Janes, Lindsay E; Sabino, Jennifer; Matthews, Jamil A; Bell, Robert L.; Thomson, J. Grant


    Objective: The rapid rate of weight loss following bariatric surgery leads to areas of excessive skin that can cause physical ailments and distortion of body image. Dissatisfaction with the excessive skin can lead patients to seek plastic surgery. This study aims to assess the changes in mental and physical quality of life after body contouring procedures in the post–bariatric surgery population. Methods: In this cross-sectional study, the 36-Item Short Form Health Survey was given to 104 pat...

  7. Pregnancy after Bariatric Surgery: A Review

    N. L. Hezelgrave


    Full Text Available Maternal obesity is a major cause of obstetric morbidity and mortality. With surgical procedures to facilitate weight loss becoming more widely available and demanded and increasing number of women becoming pregnant after undergoing bariatric surgery, it is important and timely to consider the outcome of pregnancy following bariatric surgery. This paper aims to synthesize the current evidence regarding pregnancy outcomes after bariatric surgery. It concludes that bariatric surgery appears to have positive effects on fertility and reduces the risk of gestational diabetes and preeclampsia. Moreover, there appears to be a reduced incidence of fetal macrosomia post-bariatric procedure, although there remains uncertainty about the increased rates of small-for-gestational age and intrauterine growth restricted infants, as well as premature rupture of membranes in this group. A number of case reports highlight that pregnancy following bariatric surgery is not without complications and it must be managed as high risk by the multidisciplinary team.

  11. Psychiatric and Psychosocial Aspects of Bariatric Surgery

    Guzin Mukaddes Sevincer


    Full Text Available Bariatric surgery is a treatment modality which is becoming increasingly popular in the last decade in our country and around the world. Patients who treated with a conventional methods are unable to loose sufficient weight and even they regained most of their lost weight easily. The number of patients undergoing bariatric surgery are increasing day by day considering the success of bariatric surgery with regard to lose weight fast and the improvement in co-morbid conditions. Obesity and bariatric surgery are in a reciprocal relationship both with psychiatric disorders and psychosocial variables. Relations are begin with the evaluation of a patients eligibility for surgery in terms of psychiatric and psychosocial issues at a very early stage of the process. Presence of psychopathology, level of knowledge related to the surgical procedure and patients expectations about physical, psychological and social changes that may occur after surgery are the significant parts of the evaluation of bariatric surgery patients. These components should be considered in assessing capacity of patients to comply with medical advice in post-operative stage. In this article the needs for assesment of psychiatric and psychosocial aspects of obese patients who will undergo bariatric surgery is reviewed in the light of current literature . Possible medical, psychiatric and psychosocial complications of bariatric surgery and related issues are reviewed and psycosocial factors that may be predictors of the successful outcome of bariatric surgery are discussed.Discussions around the nature of specific eating disorders seen frequently in bariatric surgery patients, wheter it is a separate entities from well known eating disorders and controversial issues such as presence or absence of psychopathology like suicide as directly consequence of the surgical procedures are summarized. Discussions about performing of psychiatric and psychosocial assesment (i.e by whom, how and

  12. Tattoo preservation during surgical procedures

    Full Text Available Stefania Tenna, Pietro Francesco Delle Femmine, Alfonso Luca Pendolino, Beniamino Brunetti, Paolo Persichetti Plastic Surgery Unit, University Campus Bio-Medico of Rome, University of Rome, Rome, Italy Abstract: In recent years, the number of people getting tattoos has continued to increase. Tattoos are much more than cultural fads and cosmetic complements, and nowadays often represent events that express the patient's personality without words. The presence of a tattoo in the surgical field may be a problem for both the patient and the surgeon. However, the relevant literature is mostly based on complications related to application of tattoos or methods used to remove them. To date, few reports have focused on the importance of preserving a tattoo during a surgical procedure, and no organized studies could be found. The aim of this paper is to provide an overview of the range of solutions that surgeons can use to preserve tattoos during surgery. A PubMed database search was done to assess other surgeons' experience. The terms "tattoo" in combination with "incision", "surgery", "surgical", or "operative" were used as key words. Following a review of the literature, photographs of patients presenting with a tattoo in the last 5 years at University Campus Bio-Medico of Rome were identified in order to determine the frequency of patients presenting with tattoos in our department. The patients were classified according to sex, age, type of surgery, number of tattoos, and tattoo location. Specific requests to preserve tattoos were recorded. Finally, an algorithm of treatment according to tattoo dimension and location is proposed. Knowledge of all the strategies available for saving tattoos is important for plastic and cosmetic surgeons. If a tattooed area needs to be operated on, surgeons should attempt, when possible, to avoid altering the tattoo in order to maximize the final cosmetic result. Keywords: tattoo incision, body contouring, surgery

    Full Text Available The Sushruta Samhita is an Ayurvedic text, by the legendary Sushruta, foundational to Ayurvedic medicine (Indian traditional medicine, with innovative chapters mainly on surgery. There is a general impression that Sushruta Samhita is only an ancient Indian Ayurvedic text book of surgery. Sushruta Samhita contains 184 chapters and description of 1120 illnesses, 700 medicinal plants, a detailed study on anatomy, 64 preparations from mineral sources and 57 preparations based on animal sources. It still retains the land mark position in the field of surgical texts. In addition to his worldwide known work of historical significance on plastic surgery, he also made similar unique contributions on numerous aspects of medicine, such as fracture and dislocations, urinary stones, skin diseases including leprosy, Pancha Karma (Purification procedures, toxicology, pediatrics, eye diseases, psychiatry, obstetrics and gynaecology, etc. A very limited conceptual work has been performed on the selected chapters of Sushruta Samhita. Therefore a review conceptual study has been carried out on the various surgical concepts of Sushruta Samhita. Outcome of this study shows, Sushruta Samhita is written in the aphorism form and the techniques described in it are eminently in line with technical abilities of the times. It is need of the hour to explore the hidden truth by decoding the versions of the texts.

  14. The Anatomy of a Weight Recidivism and Revision Bariatric Surgical Clinic

    C. J. de Gara


    Full Text Available Abstract. Weight recidivism in bariatric surgery failure is multifactorial. It ranges from inappropriate patient selection for primary surgery to technical/anatomic issues related to the original surgery. Most bariatric surgeons and centers focus on primary bariatric surgery while weight recidivism and its complications are very much secondary concerns. Methods. We report on our initial experience having established a dedicated weight recidivism and revisional bariatric surgery clinic. A single surgeon, dedicated nursing, dieticians, and psychologist developed care maps, goals of care, nonsurgical candidate rules, and discharge planning strategies. Results. A single year audit (2012 of clinical activity revealed 137 patients, with a mean age 49 ± 10.1 years (6 years older on average than in our primary clinic, 75% of whom were women with BMI 47 ± 11.5. Over three quarters had undergone a vertical band gastroplasty while 15% had had a laparoscopic adjustable gastric band. Only 27% of those attending clinic required further surgery. As for primary surgery, the role of the obesity expert clinical psychologist was a key component to achieving successful revision outcomes. Conclusion. With an exponential rise in obesity and a concomitant major increase in bariatric surgery, an inevitable increase in revisional surgery is becoming a reality. Anticipating this increase in activity, Alberta Health Services, Alberta, Canada, has established a unique and dedicated clinic whose early results are promising.

  17. A rare case of small bowel volvulus after jenjunoileal bariatric bypass requiring emergency surgery: a case report

    Patel Pranav H


    Full Text Available Abstract Introduction Bariatric surgery is on the increase throughout the world. Jejunoileal bypass bariatric procedures have fallen out of favor in western surgical centers due to the high rate of associated complications. They are, however, performed routinely in other centers and as a consequence of health tourism, management of complications related to these procedures may still be encountered. Case presentation We describe a rare case of small bowel obstruction in a 45-year-old British Caucasian woman, secondary to a volvulus of the jejunoileal anastomosis following bariatric bypass surgery. The pre-operative diagnosis was confirmed by radiology. We describe a successful surgical technique for this rare complication. Conclusions Bariatric surgery may be complicated by bowel obstruction. Early imaging is vital for diagnosis and effective management. The use of our surgical technique provides a simple and effective approach for the successful management of this bariatric complication.

    Little data exist regarding in vitro fertilization in women who have undergone bariatric surgery. Our experience with five patients suggests IVF is a safe and effective fertility treatment for these women although special considerations should be made including the type of bariatric procedure the patient underwent and relating this knowledge to symptoms the patient may experience during their IVF cycle.

  1. Stone formation and management after bariatric surgery.

    Tarplin, Sarah; Ganesan, Vishnu; Monga, Manoj


    Obesity is a significant health concern and is associated with an increased risk of nephrolithiasis, particularly in women. The underlying pathophysiology of stone formation in obese patients is thought to be related to insulin resistance, dietary factors, and a lithogenic urinary profile. Uric acid stones and calcium oxalate stones are common in these patients. Use of surgical procedures for obesity (bariatric surgery) has risen over the past two decades. Although such procedures effectively manage obesity-dependent comorbidities, several large, controlled studies have revealed that modern bariatric surgeries increase the risk of nephrolithiasis by approximately twofold. In patients who have undergone bariatric surgery, fat malabsorption leads to hyperabsorption of oxalate, which is exacerbated by an increased permeability of the gut to oxalate. Patients who have undergone bariatric surgery show characteristic 24 h urine parameters including low urine volume, low urinary pH, hypocitraturia, hyperoxaluria and hyperuricosuria. Prevention of stones with dietary limitation of oxalate and sodium and a high intake of fluids is critical, and calcium supplementation with calcium citrate is typically required. Potassium citrate is valuable for treating the common metabolic derangements as it raises urinary pH, enhances the activity of stone inhibitors, reduces the supersaturation of calcium oxalate, and corrects hypokalaemia. Both pyridoxine and probiotics have been shown in small studies to reduce hyperoxaluria, but further study is necessary to clarify their effects on stone morbidity in the bariatric surgery population.

  2. Fertility-preserving surgical procedures, techniques.

    Martinez, Alejandra; Poilblanc, Mathieu; Ferron, Gwenael; De Cuypere, Mariolene; Jouve, Eva; Querleu, Denis


    As a result of the trend toward late childbearing, fertility preservation has become a major issue in young women with gynaecological cancer. Fertility-sparing treatments have been successfully attempted in selected cases of cervical, endometrial and ovarian cancer, and gynaecologists should be familiar with fertility-preserving options in women with gynaecological malignancies. Options to preserve fertility include shielding to reduce radiation damage, fertility preservation when undergoing cytotoxic treatments, cryopreservation, assisted reproduction techniques, and fertility-sparing surgical procedures. Radical vaginal trachelectomy with laparoscopic lymphadenectomy is an oncologically safe, fertility-preserving procedure. It has been accepted worldwide as a surgical treatment of small early stage cervical cancers. Selected cases of early stage ovarian cancer can be treated by unilateral salpingo-ophorectomy and surgical staging. Hysteroscopic resection and progesterone treatment are used in young women who have endometrial cancer to maintain fertility and avoid surgical menopause. Appropriate patient selection, and careful oncologic, psychologic, reproductive and obstetric counselling, is mandatory. PMID:22503435

  3. Bariatric surgery: assessing opportunities for value innovation.

    Tarantino, David P; Smith, Darlene B


    Obesity has been increasing over the past two decades, and the amount of medical and media attention given to bariatric surgery as a promising option for morbidly obese individuals is growing. The growth of bariatric surgery also has been attributed to improved surgical technique, the increase in surgeons trained in laparoscopic procedures, as well increased public awareness with celebrities having successfully undergone surgery. The number of surgeons and hospitals offering bariatric services is increasing. How then does a surgeon or a hospital develop a competitive strategy? The first step is to understand the health-care industry. The key forces are rivalry among present competitors, and the bargaining power of suppliers and buyers. While bariatric surgery currently is in a growth phase, time and competition will force practitioners to compete on the basis of price, unless they find true competitive advantage. Value innovation, is a means of creating new marketing space by looking across the conventionally defined boundaries of business--across substitute industries, across strategic groups, across buyer groups, across complementary product and service offerings, and across the functional-emotional orientation of an industry. One can compete by offering similar services focusing primarily on cost efficiencies as the key to profitability. Alternatively, one can break free from the pack by innovating and focusing on delivering superior value to the customer. As the market for bariatric surgery becomes increasingly overcrowded, profitable growth is not sustainable without developing a clear differential advantage in the market. Value innovation allows you to develop that advantage. PMID:15846452

  4. Surgical Procedures of Morbid Obesity

    Zinat Salem


    Full Text Available Background: Surgical intervention has been recently advocated in the treatment of morbid obesity. The objective of this study was to review surgery as an alternative in the treatment of morbidly obese adolescents. Materials and Methods: This research was conducted by searching English websites such as PubMed, Up to Date, and Google Scholar, as well as some Persian websites including SID, Iranmedex, and Magiran. Articles published from 2000 to 2010 on interventional and clinical trials were reviewed for treatment of morbid obesity in adolescents. Keywords used in internet searches include obesity; adolescence; and surgery.Results: The results obtained from the studies indicated that 4% of American adolescents suffer from morbid obesity. So far, pharmacological treatment and other approaches toward this type of obesity have been inefficient. Hence, surgery was employed as one of the new approaches to the treatment of this disorder. According to the National Health Institute criteria, in the treatment of adolescent candidates for surgery, anthropometric measurements are performed together with the measurement of other co-morbidities of obesity. Adolescents whose percentiles are ≥99 are considered as morbidly obese patients. Conclusion: The results of the studies suggested that for the extremely obese adolescents, who do not respond to other types of medical interventions within 6 months, surgery can be performed. Adolescents with BMI of ≥40 kg/m2 and skeletal maturity, or those with co morbidities of obesity, or 13-year-old girls and boys ≥15 years of age can be candidates for surgery. However, the side effects of obesity should not be neglected. Therefore, before the adolescent obesity become morbid obesity, preventive measures should be taken through changes in lifestyle.

  5. Treatment of Adult Obesity with Bariatric Surgery.

    Schroeder, Robin; Harrison, T Daniel; McGraw, Shaniqua L


    In 2013, approximately 179,000 bariatric surgery procedures were performed in the United States, including the laparoscopic sleeve gastrectomy (42.1%), Roux-en-Y gastric bypass (34.2%), and laparoscopic adjustable gastric banding (14.0%). Choice of procedure depends on the medical conditions of the patient, patient preference, and expertise of the surgeon. On average, weight loss of 60% to 70% of excess body weight is achieved in the short term, and up to 50% at 10 years. Remission of type 2 diabetes mellitus occurs in 60% to 80% of patients two years after surgery and persists in about 30% of patients 15 years after Roux-en-Y gastric bypass. Other obesity-related comorbidities are greatly reduced, and health-related quality of life improves. The Roux-en-Y procedure carries an increased risk of malabsorption sequelae, which can be minimized with nutritional supplementation and surveillance. Overall, these procedures have a mortality risk of less than 0.5%. Cohort studies show that bariatric surgery reduces all-cause mortality by 30% to 50% at seven to 15 years postsurgery compared with patients with obesity who did not have surgery. Dietary changes, such as consuming protein first at every meal, and regular physical activity are critical for patient success after bariatric surgery. The family physician is well positioned to counsel patients about bariatric surgical options, the risks and benefits of surgery, and to provide long-term support and medical management postsurgery.

    In many surgeries, especially orthopedic procedures, power tools such as saws and drills are used. These tools may produce aerosolized blood and other biological material from bone and soft tissues. Surgical lasers and electrocautery tools can also produce aerosols when tissues are vaporized and condensed. Studies have been reported in the literature concerning production of aerosols during surgery, and some of these aerosols may contain infectious material. Garden et al. (1988) reported the presence of papilloma virus DNA in the fumes produced from laser surgery, but the infectivity of the aerosol was not assessed. Moon and Nininger (1989) measured the size distribution and production rate of emissions from laser surgery and found that particles were generally less than 0.5 {mu}m diameter. More recently there has been concern expressed over the production of aerosolized blood during surgical procedures that require power tools. In an in vitro study, the production of an aerosol containing the human immunodeficiency virus (HIV) was reported when power tools were used to cut tissues with blood infected with HIV. Another study measured the size distribution of blood aerosols produced by surgical power tools and found blood-containing particles in a number of size ranges. Health care workers are anxious and concerned about whether surgically produced aerosols are inspirable and can contain viable pathogens such as HIV. Other pathogens such as hepatitis B virus (HBV) are also of concern. The Occupational Safety and Health funded a project at the National Institute for Inhalation Toxicology Research Institute to assess the extent of aerosolization of blood and other tissues during surgical procedures. This document reports details of the experimental and sampling approach, methods, analyses, and results on potential production of blood-associated aerosols from surgical procedures in the laboratory and in the hospital surgical suite.

  7. Immersive Learning Experiences for Surgical Procedures.

    Cha, Young-Woon; Dou, Mingsong; Chabra, Rohan; Menozzi, Federico; State, Andrei; Wallen, Eric; Fuchs, Henry


    This paper introduces a computer-based system that is designed to record a surgical procedure with multiple depth cameras and reconstruct in three dimensions the dynamic geometry of the actions and events that occur during the procedure. The resulting 3D-plus-time data takes the form of dynamic, textured geometry and can be immersively examined at a later time; equipped with a Virtual Reality headset such as Oculus Rift DK2, a user can walk around the reconstruction of the procedure room while controlling playback of the recorded surgical procedure with simple VCR-like controls (play, pause, rewind, fast forward). The reconstruction can be annotated in space and time to provide more information of the scene to users. We expect such a system to be useful in applications such as training of medical students and nurses. PMID:27046554

  10. Techniques, assessment, and effectiveness of bariatric surgery in combating obesity

    Dimitrios K Papamargaritis


    Full Text Available Dimitrios K Papamargaritis, Dimitrios J Pournaras, Carel W Le RouxImperial Weight Centre, Imperial College London, London, UKAbstract: Obesity is an epidemic disease, and its prevalence is predicted to rise in the future. Many health and social comorbidities, such as cardiovascular disease, type 2 diabetes mellitus, cancer, nonalcoholic fatty liver disease, arthritis, infertility, eating disorders, unemployment, and low quality of life, have been associated with obesity. Nowadays, bariatric surgery is the only effective treatment for severe obesity. An increasing body of literature demonstrates significant remission of obesity-related comorbidities and an increase in life expectancy after surgical treatment. Unfortunately, serious complications can appear after surgery, and the careful preoperative assessment of patients is necessary to estimate the indications and contraindications of bariatric surgery. Recent studies report the lower complication and mortality rates when bariatric procedures are performed in high-volume centers. The purpose of this review is to describe the techniques of the currently used surgical procedures and the clinical effectiveness of bariatric surgery. Additionally, the possible complications and mortality rates after bariatric surgery are discussed.Keywords: obesity, surgery, assessment, clinical effectiveness, complications

The wide range of treatments currently used for trigeminal neuralgia is ample evidence that there is no simple answer to how it should be managed. This review will evaluate the current surgical procedures used for the treatment of trigeminal neuralgia. A critical analysis of the evidence-based studies to date was done to evaluate and compare the efficacy of the different su...

  12. Pregnancy management following bariatric surgery.

    Uzoma, A; Keriakos, R


    Bariatric surgery is gaining in popularity, due to globally increasing rates of obesity. In the UK, this has manifested as a 14-fold increase in bariatric surgery between 2004 and 2010, making it necessary to develop strategies to manage women who become pregnant following bariatric surgery. This review paper has explored all the current evidence in the literature and provided a comprehensive management strategy for pregnant women following bariatric surgery. The emphasis is on a multidisciplinary team approach to all aspects of care. Adequate pre-conception and antenatal and postnatal care is essential to good pregnancy outcomes with emphasis on appropriate nutritional supplementation. This is especially important following malabsorptive procedures. There is no evidence to suggest that pregnancy outcome is worse after bariatric surgery, though women who remain obese are prone to obesity-related risks in pregnancy. Neonatal outcome post-bariatric surgery is no different from the general population. PMID:23445128

  13. Fundamental Ethical Issues in Unnecessary Surgical Procedures.

    Tayade, Motilal Chandu; Dalvi, Shashank D


    In clinical practice performing any surgical procedure is inconsistent because all surgical procedures carry definitely some degree of risk. Worldwide every year millions of patients go under knife, but many of them are enduring great pain and shelling out thousands and dollars for surgeries they don't really need. This review work was planned with an intention to focus attention towards it with reporting cited evidences of unnecessary surgical operations and discuss ethical issues concern with it. In present review the references search included standard citations Google scholar, MEDLINE and PUBMED. We also used Google search engine for screening various news concern with highlighting this topic in community and online media. For articles we go through more than 60 articles from worldwide and 12 news media views from Google search in last one year. We used following quotes for their search-unnecessary surgeries, second opinion, ethical issues in unnecessary surgeries. Geographical variations were also kept in view. Our intension was highlighting ethical issues concern with unnecessary surgical operations. Henceforth we excluded such work that does not concern with ethical issues. Unnecessary surgery is that which is medically unjustifiable when the risks and costs are more than the likely therapeutic benefits or relief to the patient based on the patient's lifestyle requirements. To avoid or minimize such interventions basic seeding of ethics in curriculum and strict laws will definitely helpful in clinical practice. In conclusion, our aim was to highlight this major issue and underline need of competency based medical bioethics education in Indian scenario. PMID:27190833

  14. General anesthesia type does not influence serum levels of neutrophil gelatinase-associated lipocalin during the perioperative period in video laparoscopic bariatric surgery

    Adriano Fernandes; João Ettinger; Fabiano Amaral; Maria José Ramalho; Rodrigo Alves; Norma Sueli Pinheiro Módolo


    OBJECTIVES: Video laparoscopic bariatric surgery is the preferred surgical technique for treating morbid obesity. However, pneumoperitoneum can pose risks to the kidneys by causing a decrease in renal blood flow. Furthermore, as in other surgical procedures, laparoscopic bariatric surgery triggers an acute inflammatory response. Neutrophil gelatinase-associated lipocalin is an early and accurate biomarker of renal injury, as well as of the inflammatory response. Anesthetic drugs could offer s...




    Full Text Available Bariatric surgery as it is called now is not a new thing. First bariatric surgery was performed in 1954. Later the surgical remedy for bariatric surgery remained dormant till the popularity of laparoscopic surgery. Past decade has seen a tremendous increase in the number of bariatric or metabolic surgical procedures. This trend may continue because of the epidemic of obesity throughout globe and its rising prevalence among children. Advocates of bariatric surgery consider it the most effective and only treatment for morbid obesity and its co morbidities. To simplify; two types of procedures are performed. 1. Restrictive- where the intake of calories are prevented by restricting food intake. 2. The other one is malabsorptive- where food rich in calories is prevented to get absorbed. Operations based on these principles are-Laparoscopic adjustable gastric band and Vertical sleeve resection of stomach; for restrictive surgery and Laparoscopic biliopancreatic diversion with or without duodenal switch; for malabsorptive procedures. Both types have their own merits and demerits, many of which are almost unacceptable. To counter each other’s’ demerits certain combinations of both types are evolved like Roux-en-Y gastric bypass; it combines both restrictive and malabsorptive components. Each operation has its own merits and demerits. Important points for the patient and surgeon alike in the decision to proceed with bariatric operation include – the technical aspects of operation, post-operative complications including long term nutritional problems, Magnitude of initial and later steady weight loss over the period and correction of obesity related comorbidities. Here, the merits and demerits of present day laparoscopic bariatric surgical procedures are reviewed and related controversial aspects related to them are discussed. Right patient selection; right selection of operative procedure for an individual patient and more importantly right

  16. Elective plastic surgical procedures in adolescence.

    McGrath, Mary H; Schooler, Wesley G


    Adolescent patients are seeking plastic surgery to correct deformities or perceived deformities in increasing numbers. It is essential for the physician to understand the influence of perceived body image irregularity that motivates patients of all ages to request plastic surgery. The increased demand for plastic surgical procedures among young patients is caused partially to increased media exposure to the available procedures offered by plastic surgeons. A successful aesthetic procedure can have a positive influence on a mature, well-motivated teenager, while surgery on a psychologically unstable adolescent can be damaging to the patient. The American Society for Aesthetic Plastic Surgery has developed guidelines for the appropriate selection of teenagers for aesthetic plastic surgery [26]. First, the physician must "assess physical maturity, because operating on a feature that has not yet fully developed could interfere with growth or negate the benefits of surgery in later years." Second, the physician should explore emotional maturity and expectations of the teenager. The teenager should understand the goals and limitations of the proposed surgery and have realistic expectations. Third, only board certified plastic surgeons who operate in accredited facilities should perform these procedures, to ensure the safety of the teenager and the quality of the procedure. Finally, teenagers and their parents should understand the risks of surgery, postoperative restrictions on activity, and typical recovery times. The referring physician and surgeon must be aware of the positive or negative effects that plastic surgery can have on the life of a teenager and be able to select patients who have the motivation, maturity, psychosocial, and emotional attributes that will lead to patient satisfaction.

  17. Image-guidance for surgical procedures

    Contemporary imaging modalities can now provide the surgeon with high quality three- and four-dimensional images depicting not only normal anatomy and pathology, but also vascularity and function. A key component of image-guided surgery (IGS) is the ability to register multi-modal pre-operative images to each other and to the patient. The other important component of IGS is the ability to track instruments in real time during the procedure and to display them as part of a realistic model of the operative volume. Stereoscopic, virtual- and augmented-reality techniques have been implemented to enhance the visualization and guidance process. For the most part, IGS relies on the assumption that the pre-operatively acquired images used to guide the surgery accurately represent the morphology of the tissue during the procedure. This assumption may not necessarily be valid, and so intra-operative real-time imaging using interventional MRI, ultrasound, video and electrophysiological recordings are often employed to ameliorate this situation. Although IGS is now in extensive routine clinical use in neurosurgery and is gaining ground in other surgical disciplines, there remain many drawbacks that must be overcome before it can be employed in more general minimally-invasive procedures. This review overviews the roots of IGS in neurosurgery, provides examples of its use outside the brain, discusses the infrastructure required for successful implementation of IGS approaches and outlines the challenges that must be overcome for IGS to advance further.

  18. Imaging of patients treated with bariatric surgery

    Over the past few years, obesity has become a major clinical and population concern in the majority of developed countries. Obesity leads to significant systemic disorders, such as hypertension, hypercholesterolemia, hypertriglyceridemia and insulin resistance, and also increases the risk of developing cardiovascular diseases (ischemic heart disease, ischemic stroke), metabolic diseases (type 2 diabetes), certain types of cancer, and degenerative bone disorders (osteoarthritis). Health hazards associated with epidemic of obesity and potential benefits of weight loss have spurred interest in new treatment methods. Bariatric surgical procedures constitute a recognized alternative in cases where conservative management of obesity fails. Several bariatric operations can be distinguished: restrictive procedures, such as adjustable gastric band (AGB) and vertical banded gastroplasty (VBG); predominantly malabsorptive procedures, such as biliopancreatic diversion (BPD), and a combination of both methods, such as Roux-en-Y gastric bypass. The adverse consequences of surgical treatment of obesity include i.a.: intestinal anastomotic leakage, impaired intestinal permeability and internal hernia, dilatation of the stomach, gastrointestinal anastomotic stenosis, marginal ulceration, incisional hernia. Basic knowledge of procedures in the surgical treatment of obesity is of vital importance for the radiologist during evaluation of upper gastrointestinal tract in the early and late postoperative period, allowing correct interpretation of acquired images as well as recognition of typical complications

  19. Effects of Bariatric Surgery on Facial Features

    Papoian, Vardan; Mardirossian, Vartan; Hess, Donald Thomas; Spiegel, Jeffrey H.


    Background Bariatric surgeries performed in the USA has increased twelve-fold in the past two decades. The effects of rapid weight loss on facial features has not been previously studied. We hypothesized that bariatric surgery will mimic the effects of aging thus giving the patient an older and less attractive appearance. Methods Consecutive patients were enrolled from the bariatric surgical clinic at our institution. Pre and post weight loss photographs were taken and used to generate two su...

  20. Finishing procedures in orthodontic-surgical cases.

    Brunel, Jean-Michel


    To ensure optimal results, we must do our utmost to achieve targets based on order, symmetry and precision, our ultimate aim being to strive towards the desired harmony, planned contrast and exact proportions. Orthodontic-surgical treatments require specific finishing procedures, which most often call for multidisciplinary, or even transdisciplinary, collaboration. Finishing will involve the dental arches just as much as the orofacial environment. Above all, treatment of this kind demands a highly targeted approach in combination with well-defined and perfectly executed techniques. To finish a case satisfactorily, reasonable targets should be aimed for to ensure they are achieved. One must be ambitious and yet wise. A tight alliance of surgeon and orthodontist will nurture convincing and achievable projects and good, lifelong outcomes. Following the consolidation phase, roughly 4 to 6 weeks post-surgery, we can initiate the final orthodontic treatment, which, in effect, constitutes a mini-treatment in its own right. "Details make perfection, but perfection is not a detail" (Leonardo Da Vinci). "A lucid mind is the ante-chamber of intelligence" (Léo Ferré). In the order of life, every form of unity is always unique, and if each of us is unique, it is because everyone else is too. Ambition, wisdom, lucidity and efficiency will guarantee a successful result, the successful result. We must not be mere observers of our treatments, but the architect, project manager and site foreman at one and the same time. One could talk ad infinitum about finishing orthodontic-surgical cases because everything else leads up to the case-finishing and even the fullest description could never be exhaustive.

  1. The eating-related behaviours, disorders and expectations of candidates for bariatric surgery.

    Opolski, M; Chur-Hansen, A; Wittert, G


    It is important that clinicians and researchers understand the possible eating-related difficulties experienced by pre-bariatric surgery candidates, as well as their expectations of how their eating and hunger will change after surgery. This review examines English-language publications related to the eating-related behaviours, disorders and expectations of bariatric candidates. Seventy-five articles related to binge eating disorder, grazing, night eating syndrome, emotional eating, food cravings and addiction, and pre-surgical expectations of post-surgical eating in this population were critically reviewed. A variety of often problematic eating behaviours appear more common in bariatric candidates than in non-obese populations. The literature suggests that 4-45% of candidates may have binge eating disorder, 20-60% may graze, 2-42% may have night eating syndrome, 38-59% may engage in emotional eating and 17-54% may fit criteria for food addiction. Binge eating may also be more prevalent in bariatric candidates than in similarly obese non-surgical individuals. Expectations of surgery are high, with pre-surgical candidates believing their bariatric procedure will virtually guarantee significantly improved eating behaviours. Study replications are needed, and further investigation into prevalence, impacts and candidate characteristics related to disordered eating behaviours, as well as candidates' expectations of eating after surgery, will be important. Further comparisons of bariatric candidates to similarly obese non-bariatric populations will be important to understand eating-related characteristics of candidates beyond those related to their weight. Future research may be improved by the use of validated measures, replicable methodologies, minimization of data collected in circumstances where respondents may been motivated to 'fake good', use of prospective data and consistent definitions of key terminology.

  2. Endoscopic Bariatric Therapies.

    Goyal, Deepinder; Watson, Rabindra R


    Obesity and its associated cardio-metabolic comorbidities have emerged as a global pandemic. The efficacy of various hypo-caloric diets and prescription drugs has been poor with respect to sustained weight loss. Recent advancements in endoscopic technology and techniques have opened a new field of minimally invasive endoscopic treatment options for combatting obesity both as a first line and adjunctive therapy. Presently, two endoscopic space-occupying devices in the form of intragastric balloons have received FDA approval for 6-month implantation in patients within a BMI range of 30-40 kg/m(2). Furthermore, full-thickness suturing has led to the development of primary endoscopic sleeve gastroplasty and Roux-en-Y gastric bypass revision as viable endoscopic alternatives to surgical approaches. These techniques have the potential to reduce adverse events, cost, and recovery times. Looking forward, a variety of promising and novel medical devices and endoscopic platforms that target obesity and diabetes are in various phases of development and investigation. The present review aims to discuss the current and forthcoming endoscopic bariatric therapies with emphasis on relevant procedural technique and review of available evidence. PMID:27098813

  4. Post-bariatric abdominoplasty: our experience.

    Grignaffini, Eugenio; Grieco, Michele P; Bertozzi, Nicolo'; Gandolfi, Marco; Palli, Dante; Cinieri, Francesco Giovanni; Gardani, Marco; Raposio, Edoardo


    The fast increase in obesity has been followed by the growth in the demand for plastic surgery in formerly obese patients. The weight loss is accompanied by new dysfunctions and disorders of the outline of the body that affects the quality of life of the patient. Abdominoplasty is a cosmetic surgery procedure that aims to remove the excess of skin and the redundant fat. The aim of this paper was to analyze our experience in this field and to test how functional abdominoplasty improved quality of life in the operated patients. In our Unit from January 2012 to December 2014, 25 patients (18 women and 7 men, age: 24 - 79 years, mean: 51 years) underwent abdominoplastic surgery. Only at least six months after bariatric surgery the patients were eligible for functional abdominoplasty. Average weight of the patients before surgery was 83.5 kg (range 58 - 163 Kg); averege BMI was 31 (range 24.77 - 57). The average quantity of tissue removed was 1.765 Kg (range 250 g - 11,5 Kg). Minor complications rate was in agreement with the percentages reported in literature. No mortality and major complications have occurred in our series. The majority of patients undergoing post-bariatric abdominoplasty reported an improvement in the quality of life and psychological well-being. In our opinion, however, only a multidisciplinary (surgical, psychological, dietological) approach of the post-bariatric patient allows to maintain long-term aesthetic and functional results.

  5. Assessing the obese diabetic patient for bariatric surgery: which candidate do I choose?

    Raffaelli M


    Full Text Available Marco Raffaelli,1 Luca Sessa,1 Geltrude Mingrone,2 Rocco Bellantone1 1Division of Endocrine and Metabolic Surgery, 2Division of Obesity Diseases, Università Cattolica del Sacro Cuore, Rome, Italy Abstract: The worldwide prevalence of type 2 diabetes is rising in association with an increasing frequency of overweight and obesity. Bariatric-metabolic procedures are considered as additional therapeutic options, allowing improved diabetes control in most patients. Multiple factors play in concert to achieve the improvements in diabetic remission observed after bariatric-metabolic surgery. Several studies have demonstrated that bariatric-metabolic surgery is an effective treatment for type 2 diabetes when compared with conventional nonsurgical medical treatment. Because the best results are achievable in patients with a relatively short history of diabetes and less advanced controlled disease, the surgical option could be considered early, especially in morbid obese subjects (BMI ≥35 kg/m2 after failure of medical treatment. Patients with extensive weight loss are more likely to achieve type 2 diabetes remission after bariatric surgery. At present, Roux-en-Y gastric bypass seems the surgical procedure of choice because it has fewer risks than biliopancreatic diversion, and it is associated with higher weight loss and metabolic improvements compared with adjustable gastric banding. Recent evidences regarding the effectiveness of sleeve gastrectomy in diabetes remission have to be confirmed by controlled trials with longer follow-up.

  6. Perioperative Optimization of Patients Undergoing Bariatric Surgery

    C. E. Owers


    Full Text Available Bariatric surgery is fast becoming an efficient and safe method of weight reduction, especially for patients in whom conservative measures have failed. As the obese population of the world increases, so will the number of patients requesting or requiring surgical weight loss methods. Bariatric patients however have numerous co-morbidities that make their operative course more difficult, and therefore is important to have a good understanding of the important issues surrounding their pre, peri and post operative management. This article aims to educate the reader about optimal management of the bariatric surgical patient.

  7. Fish Surgery: Presurgical Preparation and Common Surgical Procedures.

    Sladky, Kurt K; Clarke, Elsburgh O


    Fish surgical procedures are commonplace in aquaria, zoos, laboratory facilities, and pet clinical practice. To incorporate fish surgery into a clinical setting, an understanding of anatomic differences between mammals and fish, bath anesthetics, and recirculating anesthesia techniques must be developed; a system or different size systems to accommodate anesthesia and surgery of particular species of concern at an institution or practice constructed; and familiar mammalian surgical principles applied with some adaptations. Common surgical procedures in fish include coeliotomy for intracoelomic mass removal, reproductive procedures, gastrointestinal foreign body removal, radiotransmitter placement, and integumentary mass excision.

  10. A Systematic Review and Meta-Analysis of Outcomes for Type 1 Diabetes after Bariatric Surgery

    Chow, Alexandra; Switzer, Noah J.; Dang, Jerry; Shi, Xinzhe; de Gara, Christopher; Birch, Daniel W.; Gill, Richdeep S.; Karmali, Shahzeer


    Background. The utility of bariatric surgery in type 1 diabetes remains controversial. The aim of the present study is to evaluate glycemic control outcomes in obese patients with type 1 diabetes after bariatric surgery. Methods. A comprehensive search of electronic databases was completed. Inclusion criteria included human adult subjects with BMI ≥35 kg/m2 and a confirmed diagnosis of type 1 diabetes who underwent a bariatric surgical procedure. Results. Thirteen primary studies (86 patients) were included. Subjects had a mean age of 41.16 ± 6.76 years with a mean BMI of 42.50 ± 2.65 kg/m2. There was a marked reduction in BMI postoperatively at 12 months and at study endpoint to 29.55 ± 1.76 kg/m2 (P diabetes leads to significant reductions in BMI and improvements in glycemic control.

  11. Post-operative bariatric surgery complications: Deficiency of nutrients

    Syed Abdul Majid Mufaqam1, Soni Dhwani Satishkumar2, Patel Palak Arvindkumar2


    Full Text Available Since more than half of the population in America falls under the category of obesity, scientists have discovered a surgical technique to reduce the weight of the obese patients. Bariatric surgery or gastric bypass surgery is a procedure that has been successful in reducing the weight for obese people. This technique requires a permanent gastric bypass (Roux-en-Y where part of the stomach and duodenum is removed. Since the size of the stomach is reduced to 20% of its original size along with the removal of duodenum – this may lead to improper absorption of several vitamins and minerals. This review showed that several vitamins and mineral deficiencies are observed in patients, post-operative bariatric surgery. Thiamin, folate, and B12 deficiencies were most commonly observed, and Vitamin A, D, C and B6 deficiencies were also seen in some cases. Iron and calcium deficiencies were also reported by some of the studies.

  12. Medical management of patients after bariatric surgery: Principles and guidelines

    Abd; Elrazek; Mohammad; Ali; Abd; Elrazek; Abduh; Elsayed; Mohamed; Elbanna; Shymaa; E; Bilasy


    Obesity is a major and growing health care concern. Large epidemiologic studies that evaluated the relationship between obesity and mortality, observed that a higher body-mass index(BMI) is associated with increased rate of death from several causes, among them cardiovascular disease; which is particularly true for those with morbid obesity. Being overweight was also associated with decreased survival in several studies. Unfortunately, obese subjects are often exposed to public disapproval because of their fatness which significantly affects their psychosocial behavior. All obese patients(BMI ≥ 30 kg/m2) should receive counseling on diet, lifestyle, exercise and goals for weight management. Individuals with BMI ≥ 40 kg/m2 and those with BMI > 35 kg/m2 with obesity-related comorbidities; who failed diet, exercise, and drug therapy, should be considered for bariatric surgery. In current review article, we will shed light on important medical principles that each surgeon/gastroenterologist needs to know about bariatric surgical procedure, with special concern to the early post operative period. Additionally, we will explain the common complications that usually follow bariatric surgery and elucidate medical guidelines in their management. For the first 24 h after the bariatric surgery, the postoperative priorities include pain management, leakage, nausea and vomiting, intravenous fluid management, pulmonary hygiene, and ambulation. Patients maintain a low calorie liquid diet for the first few postoperative days that is gradually changed to soft solid food diet within two or three weeks following the bariatric surgery. Later, patients should be monitored for postoperative complications. Hypertension, diabetes, dumping syndrome, gastrointestinal and psychosomatic disorders are among the most important medical conditions discussed in this review.

    Kassir, Radwan; Debs, Tarek; Blanc, Pierre; Gugenheim, Jean; Ben Amor, Imed; Boutet, Claire; Tiffet, Olivier


    The epidemic in obesity has led to an increase in number of so called bariatric procedures. Doctors are less comfortable managing an obese patient after bariatric surgery. Peri-operative mortality is less than 1%. The specific feature in the obese patient is that the classical signs of peritoneal irritation are never present as there is no abdominal wall and therefore no guarding or rigidity. Simple post-operative tachycardia in obese patients should be taken seriously as it is a WARNING SIGNAL. The most common complication after surgery is peritonitis due to anastomotic fistula formation. This occurs typically as an early complication within the first 10 days post-operatively and has an incidence of 1-6% after gastric bypass and 3-7% after sleeve gastrectomy. Post-operative malnutrition is extremely rare after restrictive surgery (ring, sleeve gastrectomy) although may occur after malabsorbative surgery (bypass, biliary pancreatic shunt) and is due to the restriction and change in absorption. Prophylactic cholecystectomy is not routinely carried out during the same procedure as the bypass. Superior mesenteric vein thrombosis after bariatric surgery is a diagnosis which should be considered in the presence of any postoperative abdominal pain. Initially a first etiological assessment is performed (measurement of antithrombin III and of protein C and protein S, testing for activated protein C resistance). If the least doubt is present, a medical or surgical consultation should be requested with a specialist practitioner in the management of obese patients as death rates increase with delayed diagnosis.

  16. Characterization of aerosols produced by surgical procedures: A summary

    In many types of surgery, especially orthopedic procedures, power tools such as saws and drills are used. These tools can impart considerable energy in disrupting tissue and may produce aerosolized blood and material from bone and other tissues. Surgical lasers and electrocautery tools can also produce aerosols due to vaporization of blood and tissues. A number of studies have been reported concerning production of aerosols during surgery, and some of the aerosols produced may contain infectious materials. Health care workers have expressed concern and questions pertaining to the occupational transmission of blood-borne pathogens including the human immunodeficiency virus (HIV) and hepatitis B virus (HBV) via blood aerosols during surgery. Little or no data existed characterizing the aerosols produced performing surgical procedures. Because of this lack of data, the National Institute for Occupational Safety and Health funded a project at ITRI to assess the extent of aerosolization of blood and other tissues during surgical procedures in the laboratory and in a hospital surgical suite

  19. Conserved Metabolic Changes in Nondiabetic and Type 2 Diabetic Bariatric Surgery Patients: Global Metabolomic Pilot Study.

    Sarosiek, Konrad; Pappan, Kirk L; Gandhi, Ankit V; Saxena, Shivam; Kang, Christopher Y; McMahon, Heather; Chipitsyna, Galina I; Tichansky, David S; Arafat, Hwyda A


    The goal of this study was to provide insight into the mechanism by which bariatric surgical procedures led to weight loss and improvement or resolution of diabetes. Global biochemical profiling was used to evaluate changes occurring in nondiabetic and type 2 diabetic (T2D) patients experiencing either less extreme sleeve gastrectomy or a full gastric bypass. We were able to identify changes in metabolism that were affected by standard preoperation liquid weight loss diet as well as by bariatric surgery itself. Preoperation weight-loss diet was associated with a strong lipid metabolism signature largely related to the consumption of adipose reserves for energy production. Glucose usage shift away from glycolytic pyruvate production toward pentose phosphate pathway, via glucose-6-phosphate, appeared to be shared across all patients regardless of T2D status or bariatric surgery procedure. Our results suggested that bariatric surgery might promote antioxidant defense and insulin sensitivity through both increased heme synthesis and HO activity or expression. Changes in histidine and its metabolites following surgery might be an indication of altered gut microbiome ecology or liver function. This initial study provided broad understanding of how metabolism changed globally in morbidly obese nondiabetic and T2D patients following weight-loss surgery. PMID:26881244

  1. Ethical issues in the psychosocial assessment of bariatric surgery candidates.

    Rouleau, Codie R; Rash, Joshua A; Mothersill, Kerry J


    Psychosocial evaluation is recommended prior to bariatric surgery. Practice guidelines have been published on assessment methods for bariatric surgery candidates, but they have not emphasized ethical issues with this population. This review outlines ethical and professional considerations for behavioral healthcare providers who conduct pre-surgical assessments of bariatric surgery candidates by merging ethical principles for mental health professionals with current practices in pre-surgical assessments. Issues discussed include the following: (a) establishing and maintaining competence, (b) obtaining informed consent, (c) respecting confidentiality, (d) avoiding bias and discrimination, (e) avoiding and addressing dual roles, (f) selecting and using psychological tests, and (g) acknowledging limitations of psychosocial assessments.

  2. A novel surgical procedure for bridging of massive bone defects

    Springfield Dempsey S


    Full Text Available Abstract Background Bony defects arising from tumor resection or debridement after infection, non-union or trauma present a challenging problem to orthopedic surgeons, as well as patients due to compliance issues. Current treatment options are time intensive, require more than one operation and are associated with high rate of complications. For this reason, we developed a new surgical procedure to bridge a massive long bone defect. Methods To bridge the gap, an in situ periosteal sleeve is elevated circumferentially off of healthy diaphyseal bone adjacent to the bone defect. Then, the adjacent bone is osteotomized and the transport segment is moved along an intramedullary nail, out of the periosteal sleeve and into the original diaphyseal defect, where it is docked. Vascularity is maintained through retention of the soft tissue attachments to the in situ periosteal sleeve. In addition, periosteal osteogenesis can be augmented through utilization of cancellous bone graft or in situ cortical bone adherent to the periosteal sleeve. Results The proposed procedure is novel in that it exploits the osteogenic potential of the periosteum by replacing the defect arising from resection of tissue out of a pathological area with a defect in a healthy area of tissue, through transport of the adjacent bone segment. Furthermore, the proposed procedure has several advantages over the current standard of care including ease of implementation, rapid patient mobilization, and no need for specialized implants (intramedullary nails are standard inventory for surgical oncology and trauma departments or costly orthobiologics. Conclusions The proposed procedure offers a viable and potentially preferable alternative to the current standard treatment modalities, particularly in areas of the world where few surgeons are trained for procedures such as distraction osteogenesis (e.g. the Ilizarov procedure as well as areas of the world where surgeons have little access to

  3. Nitrousoxide as a conscious sedative in minor oral surgical procedure

    Full Text Available Nitrous oxide (N 2 O is the most commonly used inhalation anesthetic in dentistry and is commonly used in emergency centers and ambulatory surgery centers as well. When used alone, it is incapable of producing general anesthesia reliably. However, as a single agent, it has an impressive safety and is excellent for providing minimal and moderate sedation for apprehensive minor oral surgical procedure. In this article, action of N 2 O in overcoming the anxiety and pain of the patient during the minor oral surgery and its advantages and disadvantages, have been reviewed.

  4. Single-incision laparoscopic bariatric surgery

    Huang Chih-Kun


    Full Text Available Background: Bariatric surgery has been established as the best option of treatment for morbid obesity. In recent years single-incision laparoscopic surgery (SILS has emerged as another modality of carrying out the bariatric procedures. While SILS represents an advance, its application in morbid obesity at present is limited. In this article, we review the technique and results of SILS in bariatric surgery. Methods: The PubMed database was searched and totally 11 series reporting SILS in bariatric surgery were identified and analyzed. The case reports were excluded. Since 2008, 114 morbidly obese patients receiving SILS bariatric surgeries were reported. Results: The procedures performed included SILS gastric banding, sleeve gastrectomy and gastric bypass. No mortality was reported in the literatures. Sixteen patients (14.05% needed an additional incision for a liver retractor, a trocar or for conversion. Only one complication of wound infection was reported in these series. All the surgeons reported that the patients were highly satisfied with the scar. Conclusion: Because of abundant visceral and subcutaneous fat and multiple comorbidities in morbid obesity, it is more challenging for surgeons to perform the procedures with SILS. It is clear that extensive development of new instruments and technical aspects of these procedures as well as randomized studies to compare them with traditional laparoscopy are essential before these procedures can be utilized in day-to-day clinical practice.

  5. Resident Exposure to Peripheral Nerve Surgical Procedures During Residency Training.

    Gil, Joseph A; Daniels, Alan H; Akelman, Edward


    Background Variability in case exposures has been identified for orthopaedic surgery residents. It is not known if this variability exists for peripheral nerve procedures. Objective The objective of this study was to assess ACGME case log data for graduating orthopaedic surgery, plastic surgery, general surgery, and neurological surgery residents for peripheral nerve surgical procedures and to evaluate intraspecialty and interspecialty variability in case volume. Methods Surgical case logs from 2009 to 2014 for the 4 specialties were compared for peripheral nerve surgery experience. Peripheral nerve case volume between specialties was performed utilizing a paired t test, 95% confidence intervals were calculated, and linear regression was calculated to assess the trends. Results The average number of peripheral nerve procedures performed per graduating resident was 54.2 for orthopaedic surgery residents, 62.8 for independent plastic surgery residents, 84.6 for integrated plastic surgery residents, 22.4 for neurological surgery residents, and 0.4 for surgery residents. Intraspecialty comparison of the 10th and 90th percentile peripheral nerve case volume in 2012 revealed remarkable variability in training. There was a 3.9-fold difference within orthopaedic surgery, a 5.0-fold difference within independent plastic surgery residents, an 8.8-fold difference for residents from integrated plastic surgery programs, and a 7.0-fold difference within the neurological surgery group. Conclusions There is interspecialty and intraspecialty variability in peripheral nerve surgery volume for orthopaedic, plastic, neurological, and general surgery residents. Caseload is not the sole determinant of training quality as mentorship, didactics, case breadth, and complexity play an important role in training. PMID:27168883

  6. Mandatory weight loss during the wait for bariatric surgery.

    Glenn, Nicole M; Raine, Kim D; Spence, John C


    Mandatory presurgical, behavior-induced weight loss, although not standard, is a relatively common practice among bariatric surgical clinics. We explore the patient's experience of this practice using phenomenology. We gathered experiential accounts from 7 individuals waiting to have the procedure at a large publically funded clinic in western Canada. In writing this article, we focused on four phenomenological themes: "just nod your head and carry on"-silencing through the ideal; waiting and weighing-promoting weight consciousness to the weight conscious; paying for surgical approval through weight loss; and presurgical weight loss and questioning the need for weight loss surgery altogether. We contrast the experiential findings with the clinical literature to question the impact and possible (unintended or unexpected) effects the practice might have, particularly on patients' lives. We situate this article within a larger discussion about the possible contribution of experiential knowledge to clinical guidelines, practices, and pedagogies. PMID:25185162

  7. Surgical procedure of Free Flap. Main nursing care

    Manuel Molina López


    Full Text Available The free flap surgical technique is used to cover extensive skin loss areas and situations where no flap is available, or in axial zones. The great breackthrough in the field of reconstructive surgical techniques and the creation of new units where these complex techniques are used, means that the nursing staff who work in these hospital units are adquiring greater protagonism in caring for, and the subsequent success of this type of surgery in which the problems of collaboration in all the perioperative phases depend entirely on the nursing team.The collaborative nursing problems could be defined as real or potential health problems, where users need nursing staff to follow the treatment and control procedures prescribed by other professional, generally doctors, who control and are responsible for the final outcome.While planning collaborative objectives and activities it should be taken into account that the function of the nursing staff is twofold: on the one hand, the patient must be taken care of as prescribed by other professionals and, on the other hand, it should bring into play cognitive elements (knowledge and know-how and clinical judgment when executing these in controlling the patients evolution.In this article our intention is to give an interesting and comprehensive description of the free flap surgical technique, its pros and cons, and identify the principal collaborative problems which nursing will have to deal with in each one of the perioperative phases, the number and specific nature of such oblige nursing on many occasions, to update and/or acquire new skills.

  8. Surgical Management of Chronic Lymphedema; Introducing an Innovative Procedure

    Seyed-Reza Mousavi


    Full Text Available Objective: Lymphedema is the result of impaired lymphatic drainage from the affected organ. This abnormality can be primary or secondary. Different nonoperative and operative approaches have been introduced to treat chronic lymphedema. In this study, we describe a new surgical technique and compare its results with other more commonplace methods. Methods:Fifty-nine patients with the diagnosis of chronic lower extremity lymphdema who had not responded to nonoperative management for at least 6 months, were included in the study. They were collected during 15 years between March 1987 and March 2002. Doppler ultrasonography of deep venous system to confirm its patency was routinely performed in the most of patients. Then, they underwent surgery and were followed for at least 1 year postoperatively. Findings: All the patients were operated by our new technique which is a modified form of the Homans. The outcome was excellent and 89.2% of patients were devoid of complication. A 10.8% total complication rate was inevitable. The most common complication was wound seroma. Conclusion: According to the difficulties with treatment of chronic lymphedema and variety of surgical options, our method can be an excellent and even the standard operative procedure to treat intractable forms of disease.

    Full Text Available Context Morbid obesity is associated with various co-morbidities, including chronic venous insufficiency. Bariatric surgery is the only effective treatment for morbid obesity, but with potential risks and possible complications, including venous thromboembolism. Objective To determine the prevalence of clinical and ultrasonographic signs of chronic venous insufficiency in morbid obese patients in preparation for bariatric surgery and the incidence of post-operative venous thromboembolic disease. Methods Patients on work-up for bariatric surgery of Centro Terapêutico Especializado em Fígado (CETEFI and Pro-Gastro surgical teams of the Hospital Beneficência Portuguesa de São Paulo were included. The analysed data were pre-operative findings for venous insufficiency (CEAP - clinical, etiological, anatomical, physiopathologic - classification and venous ultrassonographic findings, type of surgery (open or laparoscopic, abdominal circumference, body mass index (BMI and post-operative ultrassonography search for venous insufficiency and deep venous thrombosis. Results Between March 2007 and December 2009, 95 patients candidates for bariatric surgery had clinical and duplex scan evaluation of the lower limbs venous system. Of the 95 patients, 53 were submitted to the surgical procedure. There was a predominance of women (77.9%, the average age was 38.5 years, average preoperative weight 124.6 kg and average BMI of 45.5 kg/m2. Regarding obesity, 16.8% were obese, and 83.1% were morbidly obese. In relation to the venous findings, 86.3% of the patients did fit CEAP classification less than 3 and 13.7% greater than or equal to 3. Among the post-operative complications, there were four cases of wound infection. Three patients developed post-operative distal venous thrombosis (7.5%, but no one had clinically manifested pulmonary embolism. Conclusion No relation between BMI, CEAP classification and venous ultrassonographic findings were found. Although

  10. Soft Tissue Surgical Procedures for Optimizing Anterior Implant Esthetics

    Andreas L. Ioannou


    Full Text Available Implant dentistry has been established as a predictable treatment with excellent clinical success to replace missing or nonrestorable teeth. A successful esthetic implant reconstruction is predicated on two fundamental components: the reproduction of the natural tooth characteristics on the implant crown and the establishment of soft tissue housing that will simulate a healthy periodontium. In order for an implant to optimally rehabilitate esthetics, the peri-implant soft tissues must be preserved and/or augmented by means of periodontal surgical procedures. Clinicians who practice implant dentistry should strive to achieve an esthetically successful outcome beyond just osseointegration. Knowledge of a variety of available techniques and proper treatment planning enables the clinician to meet the ever-increasing esthetic demands as requested by patients. The purpose of this paper is to enhance the implant surgeon’s rationale and techniques beyond that of simply placing a functional restoration in an edentulous site to a level whereby an implant-supported restoration is placed in reconstructed soft tissue, so the site is indiscernible from a natural tooth.

  11. Effects of bariatric surgery on the body composition of adults

    Tiago Wally Hartwig


    Full Text Available The most alarming cases are known as morbidly obese. An effective method to change the anthropometric characteristics of this population with excess body weight and high fat mass is bariatric surgery. The objective of this study was to analyze the body composition of morbidly obese patients undergoing bariatric surgery in the city of Pelotas, Southern Brazil. In a prospective cohort study, a group of morbidly obese patients was followed up 30 days before and 30 days after surgery. The sample consisted of 123 patients who underwent vertical banded Roux-en-Y gastroplasty between April 2003 and May 2010. Body composition (fat percentage was determined by bioelectrical impedance analysis. The mean age of the patients was 36.1 ± 8.8 years and mean body weight loss was 14.1 ± 6.0 kg (p<0.001. The mean reduction in body mass index (BMI was 5.2 ± 2.1 kg/m2 (p<0.001. Body fat percentage and fat mass were reduced by 2.8% (p<0.001 and 9.7 ± 4.9 kg (p<0.001, respectively. In addition, there was a reduction of 4.4 ± 3.4 kg (p<0.001 in lean mass. We concluded that the surgical procedure significantly reduced body weight, BMI, fat percentage and fat mass and is an alternative when conventional treatments appear ineffective.

  12. Cosmetics for the eye area after cosmetic surgical procedures.

    Ogden-West, N


    Cosmetic enhancement of the eye area after esthetic surgery allows the patient to get back into the mainstream of life faster. It also improves their psychic state by blocking out discoloration, helping to disguise incision scars and artistically coloring the face to enhance the results of the surgery. The patients automatically feel better, when they look better. After a surgical procedure, there are temporary and permanent structural changes that appear with blepharoplasty and laser surgery. Although these surgeries will take away loose skin, puffy fat deposits and wrinkles, they do not change the bone structure or eye placement. Before starting a makeup application, analyzation of the eyes for their structural features help the artist know the value of colors to be used. The measuring points of the brow along with the importance of framing the eye will also be discussed. Once the brows and the eyes have been analyzed, the artist needs to take into consideration the personality of the patient. This helps the artist decide on the colors, value, intensity and design which will be applied to the patient. Before eye makeup can be applied, the use of primers, concealers and/or camouflage creams will be used to block out any discoloration in the eye area. We will look at concerns in formulation of products that will go around the eyes after surgery. The application of cosmetic products should be used as an accessory. Women have a variety of dress styles: casual, business or evening. The style of makeup application should work in conjunction with what they are wearing and how they are feeling at the time. Just as there are many facets to a woman, there are various styles of application to fit her personality. PMID:10393519

  13. Endocrine and metabolic aspects of the management of patients undergoing bariatric surgery. Review of clinical recommendations.

The basic recommendations are reviewed in this article.

  14. Metabolic Bone Disease in the Bariatric Surgery Patient

    Susan E. Williams


    Full Text Available Bariatric surgery has proven to be a life-saving measure for some, but for others it has precipitated a plethora of metabolic complications ranging from mild to life-threatening, sometimes to the point of requiring surgical revision. Obesity was previously thought to be bone protective, but this is indeed not the case. Morbidly obese individuals are at risk for metabolic bone disease (MBD due to chronic vitamin D deficiency, inadequate calcium intake, sedentary lifestyle, chronic dieting, underlying chronic diseases, and the use of certain medications used to treat those diseases. After bariatric surgery, the risk for bone-related problems is even greater, owing to severely restricted intake, malabsorption, poor compliance with prescribed supplements, and dramatic weight loss. Patients presenting for bariatric surgery should be evaluated for MBD and receive appropriate presurgical interventions. Furthermore, every patient who has undergone bariatric surgery should receive meticulous lifetime monitoring, as the risk for developing MBD remains ever present.

  17. Tissue-Specific Effects of Bariatric Surgery Including Mitochondrial Function

    Simon N. Dankel


    Full Text Available A better understanding of the molecular links between obesity and disease is potentially of great benefit for society. In this paper we discuss proposed mechanisms whereby bariatric surgery improves metabolic health, including acute effects on glucose metabolism and long-term effects on metabolic tissues (adipose tissue, skeletal muscle, and liver and mitochondrial function. More short-term randomized controlled trials should be performed that include simultaneous measurement of metabolic parameters in different tissues, such as tissue gene expression, protein profile, and lipid content. By directly comparing different surgical procedures using a wider array of metabolic parameters, one may further unravel the mechanisms of aberrant metabolic regulation in obesity and related disorders.

    B Kolar


    Full Text Available Surgical management is considered for specific indications in Crohn′s disease and a wide variety of surgeries is performed. The purpose of this pictorial essay is to depict manifestations of Crohn′s disease that indicates surgery, various surgical procedures that are performed, and the complications arising from these surgical procedures. Surgical indications including obstruction due to strictures or adhesions, fistulae and abscesses, and surgeries for these conditions, such as, ileocecectomy, stricturoplasty, small bowel resection, fecal diversion, segmental colectomy, and lysis of adhesions and their complications will be discussed and their imaging will also be illustrated.

  20. Requirements on surgical hand disinfection and modified procedures

    Assadian, Ojan


    Full Text Available The special importance of the surgeon's hand in the multi-barrier concept to prevent surgical site infections is based on two facts: the resident flora on the hands cannot be totally eradicated and the surgical glove is no reliable barrier for micro-organisms. The aim of the pre-surgical disinfection is therefore to eliminate the transient flora and reduce the resident flora to the greatest possible amount for the duration of the surgery. New experimental evidence has led to changes in the pre-surgical disinfection. The article summarises the actual knowledge and practice of the pre-surgical disinfection with special focus on pre-conditions for hand disinfection, requirements on the efficacy and the influence on a previous hand wash, duration of disinfection and practical implementation. Because some countries still prefer scrubs to alcoholic rubs, we compare both methods based on efficacy, compliance and dermal tolerance with the conclusion that rubs are superior to scrubs in all evaluated categories.

  1. Becoming a normal guy: Men making sense of long-term bodily changes following bariatric surgery

    Karen Synne Groven


    Full Text Available Background: To date, research on bodily changes following bariatric surgery has focused predominantly on women, leaving the long-term experience of men relatively unexplored. In this paper, we draw on interviews with men who have undergone an irreversible gastric bypass procedure to explore their bodily changes more than 4 years post-surgery. We apply a phenomenological framework that draws on Leder's perspectives on the “disappearing” and “dys-appearing” body, combined with a gender-sensitive lens that draws on Connell's theory of hegemonic masculinity and Robertson's conceptions of embodied masculinity. Findings: Our principal finding was that the men negotiated their bodily changes following bariatric surgery in profoundly ambivalent ways. Although they enthusiastically praised the surgery for improving their health, self-esteem, and social functioning, they also emphasized their efforts to cope with post-surgical side effects and life-threatening complications. Our analysis elaborates on their efforts to adjust to and come to terms with these changes, focusing on episodes of hypoglycemia, severe pain and internal herniation, and the significance of physical activity and exercise. Conclusions: Our findings point to the need to acknowledge men's ways of making sense of profound and ongoing bodily changes following bariatric surgery and how these negotiations are closely intertwined with masculine ideals of embodiment and social value.

  2. General anesthesia type does not influence serum levels of neutrophil gelatinase-associated lipocalin during the perioperative period in video laparoscopic bariatric surgery

    Adriano Fernandes


    Full Text Available OBJECTIVES: Video laparoscopic bariatric surgery is the preferred surgical technique for treating morbid obesity. However, pneumoperitoneum can pose risks to the kidneys by causing a decrease in renal blood flow. Furthermore, as in other surgical procedures, laparoscopic bariatric surgery triggers an acute inflammatory response. Neutrophil gelatinase-associated lipocalin is an early and accurate biomarker of renal injury, as well as of the inflammatory response. Anesthetic drugs could offer some protection for the kidneys and could attenuate the acute inflammatory response from surgical trauma. The objective of this study was to compare the effects of two types of anesthetics, propofol and sevoflurane, on the serum levels of neutrophil gelatinase-associated lipocalin during the perioperative period in laparoscopic bariatric surgery. METHODS: Sixty-four patients scheduled for laparoscopic bariatric surgery were randomized into two anesthesia groups and were administered either total intravenous anesthesia (propofol or inhalation anesthesia (sevoflurane. In the perioperative period, blood samples were collected at three time points (before anesthesia, 6 hours after pneumoperitoneum and 24 hours after pneumoperitoneum and urine output was measured for 24 hours. Acute kidney injuries were evaluated by examining both the clinical and laboratory parameters during the postoperative period. The differences between the groups were compared using non-parametric tests. ReBEC ( RBR-8wt2fy RESULTS: None of the patients developed an acute kidney injury during the study and no significant differences were found between the serum neutrophil gelatinase-associated lipocalin levels of the groups during the perioperative period. CONCLUSION: The choice of anesthetic drug, either propofol or sevoflurane, did not affect the serum levels of neutrophil gelatinase-associated lipocalin during the perioperative period in

  3. Surgical Success in Chronic Pancreatitis: Sequential Endoscopic Retrograde Cholangiopancreatography and Surgical Longitudinal Pancreatojejunostomy (Puestow Procedure).

    Ford, Kathryn; Paul, Anu; Harrison, Phillip; Davenport, Mark


    Introduction Chronic pancreatitis (CP) can be a cause of recurrent, severe, disabling abdominal pain in children. Surgery has been suggested as a useful therapy, although experience is limited and the results unpredictable. We reviewed our experience of a two-stage protocol-preliminary endoscopic retrograde cholangiopancreatography (ERCP) and duct stenting, and if symptoms resolved, definitive surgical decompression by longitudinal pancreatojejunostomy (LPJ) (Puestow operation). Patients and Methods This is a single-center, retrospective review of children with established CP who underwent an LPJ between February 2002 and September 2012. A questionnaire was completed (incorporating visual analog scale pain and lifestyle scores) to assess functional outcome. Data are expressed as median (range). Results In this study, eight (M:F ratio of 4:4) children underwent an LPJ and one female child had a more limited pancreatojejunostomy anastomosis following preliminary ERCP and stent placement where possible. Diagnoses included hereditary pancreatitis (n = 3), idiopathic or structural pancreatitis (n = 5), and duct stricture following radiotherapy (n = 1). Median duct diameter presurgery was 5 (4-11) mm. Endoscopic placement of a Zimmon pancreatic stent was possible in six with relief of symptoms in all. Median age at definitive surgery was 11 (range, 7-17) years with a median postoperative stay of 9 (range, 7-12) days and a follow-up of 6 (range, 0.5-12) years. All children reported markedly reduced episodes of pain postprocedure. One developed diabetes mellitus, while three had exocrine deficiency (fecal elastase < 200 µg/g) requiring enzyme supplementation. The child with limited LPJ had symptomatic recurrence and required restenting and further surgery to widen the anastomosis to become pain free. Conclusion ERCP and stenting provide a therapeutic trial to assess possible benefit of a definitive duct drainage procedure. LPJ-the modified Puestow

  6. Video recording of cardiac surgical procedures: what the surgeon needs to know.

    Massetti, M; Neri, E; Banfi, C; Buklas, D; Gerard, J L; Vigano, M; Chitwood, R W


    In the past, rudimentary devices were used to record surgical operations. Currently, the introduction of technologic advances such as high-definition television and the miniaturization of high-resolution digital video cameras provides an opportunity for making significantly enhanced surgical records. These enhancements, coupled with the recent advances in telemedicine and surgical simulation, will improve cardiac surgery training and skill acquisition, decrease operative times and costs, minimize morbidity, and improve overall patient care. The present paper provides a discussion of the media technology offered to surgeons for recording a surgical procedure on video. Hardware technology, including different types of cameras and analogical or digital post processing methods, are reviewed with a surgical ''eye''. This ''how to'' paper provides practical suggestions to surgeons in order to enhance surgical video recording. PMID:18670389

  9. ANTIBIOTIC PROPHYLAXIS IN BARIATRIC SURGERY: a continuous infusion of cefazolin versus ampicillin/sulbactam and ertapenem

    Álvaro Antônio Bandeira FERRAZ


    Full Text Available Background The incidence of surgical site infection in bariatric patients is significant and the current recommendations for antibiotic prophylaxis are sometimes inadequate. Objective The aim of this study was to analyze the effect of three prophylactic antibiotic regimens on the incidence of surgical site infection. Methods A prospective, cross-sectional study was conducted between January 2009 and January 2013 in which 896 Roux-en-Y gastric bypasses were performed to treat obesity. The study compared three groups of patients according to the perioperative antibiotic prophylaxis administered intravenously and beginning at anesthesia induction: Group I consisting of 194 patients treated with two 3-g doses of ampicillin/sulbactam; Group II with 303 patients treated with a single 1-g dose of ertapenem; and Group III with 399 patients treated with a 2-g dose of cefazolin at anesthesia induction followed by a continuous infusion of cefazolin 1g throughout the surgical procedure. The rate of surgical site infection was analyzed, as well as its association with age, sex, preoperative weight, body mass index and comorbidities. Results The rates of surgical site infection were 4.16% in the group treated prophylactically with ampicillin/sulbactam, 1.98% in the ertapenem group and 1.55% in the continuous cefazolin group. Conclusion The prophylactic use of continuous cefazolin in surgeries for morbid obesity shows very promising results. These findings suggest that some prophylactic regimens need to be reconsidered and even substituted by more effective therapies for the prevention of surgical site infections in bariatric patients.

  10. Use of Articaine in loco-regional anesthesia for day care surgical procedures

    Sukhminder Jit Singh Bajwa


    Full Text Available The popularity of day case surgical procedures has increased immensely over the last few years. Though various techniques are available for carrying out day-case anesthesia, preference for a technique depends upon the type of procedure, patient profile, associated co-morbidities, available infrastructure and back-up facilities, monitoring devices and comfort of the attending anesthesiologist with the technique. Day-case spinal anesthesia for ambulatory surgery has gained a wider acceptance and numerous drugs are available for use in loco-regional anesthesia. Articaine is one such amide local anesthetic drug which is increasingly being used in day care surgeries. Properties of articaine such as faster onset, shorter elimination time and rapid recovery from sensory and motor blockade make it a very useful agent in local and regional anesthesia for day care surgical procedures. This article aims to review these properties of articaine so as to evaluate how useful articaine can be for ambulatory surgical procedures.

  11. A Comparative Evaluation for Biologic Width following Surgical Crown Lengthening Using Gingivectomy and Ostectomy Procedure

    Kiran Kumar Ganji


    Full Text Available Surgical crown lengthening has been proposed as a means of facilitating restorative procedures and preventing injuries in teeth with structurally inadequate clinical crown or exposing tooth structure in the presence of deep, subgingival pathologies which may hamper the access for proper restorative measures. Histological studies utilizing animal models have shown that postoperative crestal resorption allowed reestablishment of the biologic width. However, very little has been done in humans. Aims. The purpose of the study was to evaluate the potential changes in the periodontal tissues, particularly the biologic width, following surgical crown lengthening by two surgical procedures before and after crown placement. Methods and Material. Twenty (20 patients who needed surgical crown lengthening to gain retention necessary for prosthetic treatment and/or to access caries, tooth fracture, or previous prosthetic margins entered the study. The following parameters were obtained from line angles of treated teeth (teeth requiring surgical crown lengthening and adjacent sites: Plaque and Gingival Indices (PI & (GI, Position of Gingival Margin from reference Stent (PGMRS, Probing depth (PD, and Biologic Width (BW. Statistical Analysis Used. Student “t” Test. Results. Initial baseline values of biologic width were 2.55 mm (Gingivectomy procedure B1 Group and 1.95 mm (Ostectomy procedure B2 Group and after surgical procedure the values were 1.15 mm and 1.25 mm. Conclusions. Within the limitations of the study the biologic width, at treated sites, was re-established to its original vertical dimension by 3 months. Ostectomy with apically positioned flap can be considered as a more effective procedure than Gingivectomy for Surgical Crown Lengthening.

    There are many established plastic surgical techniques to address effectively the lax, redundant tissue of the post–weight loss patient. Surgeons who are beginning their involvement in treating these patients are discovering that standard techniques are not always applicable to this rapidly growing group of patients and their extraordinary surgical challenges. Unique to the buttocks and the post-bariatric female breast is a tendency for these areas not only to become loose and ptotic but also...

  15. An adjunctive minor surgical procedure for increased rate of retraction

    Prabhakar Krishnan


    Full Text Available Introduction: Orthodontic treatment is based on the principle that if prolonged pressure is applied to the tooth, tooth movement will occur as the bone around the tooth re-models. In this study osteotomy of buccal alveolar plate and undermining of interseptal bone was performed at premolar extraction site and rate of en-masse retraction and canine retraction was evaluated. Materials and Methods: Patients between the age of 18 and 25 years, requiring retraction of anterior teeth are selected for the study. Osteotomy with undermining of interseptal bone at the extraction site was performed. The procedure was performed on all four quadrants. Results: The average retraction in the maxillary arch was 0.98 mm/quadrant in 3 weeks, i.e., a total retraction of 5.89 mm in a span of 9 weeks. The average retraction in the mandibular arch was 0.96 mm/quadrant in 3 weeks, i.e., a total retraction of 5.75 mm in a span of 9 weeks. Conclusion: This method of achieving faster en masse retraction immediately after extraction definitely reduced the initial retraction time. We recommend that such procedure must be carried out with appropriate anchorage conservation methods.

  17. Insulinoma After Bariatric Surgery: Diagnostic Dilemma and Therapeutic Approaches.

    Mulla, Christopher M; Storino, Alessandra; Yee, Eric U; Lautz, David; Sawnhey, Mandeep S; Moser, A James; Patti, Mary-Elizabeth


    Hypoglycemia is increasingly recognized as a complication of bariatric surgery. Typically, hypoglycemia does not appear immediately postoperatively, but rather more than 1 year later, and usually occurs 1-3 h after meals. While rare, insulinoma has been reported after bariatric surgery. Clinical factors which should raise suspicion for insulinoma and the need for comprehensive clinical and biochemical evaluation include hypoglycemia occurring in the fasting state, predating bariatric surgery, and/or worsening immediately postoperatively, and lack of response to conservative therapy. Localization and successful resection of insulinoma can be achieved using novel endoscopic ultrasound and surgical approaches. In summary, hypoglycemia presenting shortly after gastric bypass or with a dominant fasting pattern should be fully evaluated to exclude insulinoma. Additionally, evaluation prior to gastric bypass should include screening for history of hypoglycemia symptoms. PMID:26846121

  18. Prevalence of Neoplastic Diseases in Pet Birds Referred for Surgical Procedures

    Castro, Patrícia F.; Fantoni, Denise T.; Miranda, Bruna C.; Matera, Julia M.


    Neoplastic disease is common in pet birds, particularly in psittacines, and treatment should be primarily aimed at tumor eradication. Nineteen cases of pet birds submitted to diagnostic and/or therapeutic surgical procedures due to neoplastic disease characterized by the presence of visible masses were retrospectively analyzed; affected species, types of neoplasms and respective locations, and outcomes of surgical procedures were determined. All birds undergoing surgery belonged to the order Psittaciformes; the Blue-fronted parrot (Amazona aestiva) was the prevalent species. Lipoma was the most frequent neoplasm in the sample studied. Most neoplasms affected the integumentary system, particularly the pericloacal area. Tumor resection was the most common surgical procedure performed, with high resolution and low recurrence rates.

    Castro, Patrícia F; Fantoni, Denise T; Miranda, Bruna C; Matera, Julia M


    Neoplastic disease is common in pet birds, particularly in psittacines, and treatment should be primarily aimed at tumor eradication. Nineteen cases of pet birds submitted to diagnostic and/or therapeutic surgical procedures due to neoplastic disease characterized by the presence of visible masses were retrospectively analyzed; affected species, types of neoplasms and respective locations, and outcomes of surgical procedures were determined. All birds undergoing surgery belonged to the order Psittaciformes; the Blue-fronted parrot (Amazona aestiva) was the prevalent species. Lipoma was the most frequent neoplasm in the sample studied. Most neoplasms affected the integumentary system, particularly the pericloacal area. Tumor resection was the most common surgical procedure performed, with high resolution and low recurrence rates.

  1. Use of positive pressure in preoperative and intraoperative of bariatric surgery and its effect on the time of extubation

    Letícia Baltieri


    Full Text Available BACKGROUND AND OBJECTIVE: To investigate the influence of intraoperative and preoperative positive pressure in the time of extubation in patients undergoing bariatric surgery. METHOD: Randomized clinical trial, in which 40 individuals with a body mass index between 40 and 55 kg/m2, age between 25 and 55 years, nonsmokers, underwent bariatric surgery type Roux-en-Y gastric bypass by laparotomy and with normal preoperative pulmonary function were randomized into the following groups: G-pre (n = 10: individuals who received treatment with noninvasive positive pressure before surgery for 1 h; G-intra (n = 10: individuals who received positive end-expiratory pressure of 10 cm H2O throughout the surgical procedure; and G-control (n = 20: not received any preoperative or intraoperative intervention. Following were recorded: time between induction of anesthesia and extubation, between the end of anesthesia and extubation, duration of mechanical ventilation, and time between extubation and discharge from the post-anesthetic recovery. RESULTS: There was no statistical difference between groups. However, when applied to the Cohen coefficient, the use of positive end-expiratory pressure of 10 cm H2O during surgery showed a large effect on the time between the end of anesthesia and extubation. About this same time, the treatment performed preoperatively showed moderate effect. CONCLUSION: The use of positive end-expiratory pressure of 10 cm H2O in the intraoperative and positive pressure preoperatively, influenced the time of extubation of patients undergoing bariatric surgery.

  7. Guidelines on the facilities required for minor surgical procedures and minimal access interventions.

    Humphreys, H


    There have been many changes in healthcare provision in recent years, including the delivery of some surgical services in primary care or in day surgery centres, which were previously provided by acute hospitals. Developments in the fields of interventional radiology and cardiology have further expanded the range and complexity of procedures undertaken in these settings. In the face of these changes there is a need to define from an infection prevention and control perspective the basic physical requirements for facilities in which such surgical procedures may be carried out. Under the auspices of the Healthcare Infection Society, we have developed the following recommendations for those designing new facilities or upgrading existing facilities. These draw upon best practice, available evidence, other guidelines where appropriate, and expert consensus to provide sensible and feasible advice. An attempt is also made to define minimal access interventions and minor surgical procedures. For minimal access interventions, including interventional radiology, new facilities should be mechanically ventilated to achieve 15 air changes per hour but natural ventilation is satisfactory for minor procedures. All procedures should involve a checklist and operators should be appropriately trained. There is also a need for prospective surveillance to accurately determine the post-procedure infection rate. Finally, there is a requirement for appropriate applied research to develop the evidence base required to support subsequent iterations of this guidance.

  8. Influence of Bariatric Surgery on Remission of Type 2 Diabetes

    Paweł Nalepa


    Full Text Available The plague of obesity afflicts an increasing group of people. Moreover type 2 diabetes, which is the most serious illness accompanying excessive weight, is becoming more and more common. Traditional methods of obesity treatment, such as diet and physical exercise, fail. This applies especially to people with class III obesity. The only successful way of treating obesity in their case is bariatric surgery. There are three types of bariatric surgery: restrictive procedures (reducing stomach volume, malabsorptive procedures, and mixed procedures, which combine both methods. In spite of the risk connected with the surgery and complications after it, bariatric procedures are advised to patients with class III obesity and class II with an accompanying illness which increases the probability of death. It has been proved that bariatric surgery not only eliminates obesity but also very frequently (in 90�0of cases leads to the remission of type 2 diabetes. Moreover, the remission occurs very fast – it takes place a long time before the patients reduce their weight, even within a few days after surgery. Detailed studies have shown that the remission of diabetes is caused mostly by the change of the gastro-intestinal hormones’ profile, resulting from the surgery. These hormones include GLP-1, GIP, peptide YY, ghrelin and oxyntomodulin. Additionally, the change of the amount of adipose tissue after the surgery influences the level of adipokines, i.e. the hormones of the adipose tissue, among which the most important are leptin, adiponectin and resistin. Thus, bariatric surgery not only changes the shape of the gastrointestinal tract but it also modulates the hormonal activity. Bariatric surgery is considered as therapy not only for the obese but also for diabetic patients.

  9. The effects of bariatric surgeries on type 2 diabetes mellitus

    Lerd Ng, Jia; Ortiz, Roberto; Hughes, Tyler; Abou Ghantous, Michel; Bouhali, Othmane; Arredouani, Abdelilah; Allen, Roland


    We consider a scientific mystery which is of central importance in treating the most rapidly emerging national and global health threat: type 2 diabetes mellitus. The mystery involves a surprising effect of certain bariatric surgeries, and specifically Roux-en-Y gastric bypass (RYGB), a procedure which bypasses most of the stomach and upper intestine. An unanticipated result is that RYGB is usually found to contribute within only a few days to glucose homeostasis. This means the surgery can immediately cure patients even before they start losing weight. We are investigating this wondrous biochemical response with a quantitative model which includes the most important mechanisms. One of the major contributors is glucagon-like peptide 1 (GLP-1), an incretin whose concentration is found to increase by a large amount right after the RYGB surgical procedure. However, our results, in conjunction with the experimental and medical data, indicate that other substances must also contribute. If these substances can be definitively identified, it may be possible to replace the surgery with pharmaceuticals as the preferred treatment for type 2 diabetes.

  11. Surgical procedures performed in the neonatal intensive care unit on critically ill neonates: feasibility and safety

    Transferring unstable, ill neonates to and from the operating rooms carries significant risks and can lead to morbidity. We report on our experience in performing certain procedures in critically ill neonates in the neonatal intensive care unit (NICU). We examined the feasibility and safety for such an approach. All surgical procedures performed in the NICU between January 1999 and December 2005 were analyzed in terms of demographic data, diagnosis, preoperative stability of the patient, procedures performed, complications and outcome. Operations were performed at beside in the NICU in critically ill, unstable neonates who needed emergency surgery, in neonates of low birth weight (<1000 gm) and in neonates on special equipments like higher frequency ventilators and nitrous oxide. Thirty-seven surgical procedures were performed including 12 laparotomies, bowel resection and stomies, 7 repairs of congenital diaphragmatic hernias, 4 ligations of patent ductus arteriosus and various others. Birth weights ranged between 850 gm and 3500 gm (mean 2000 gm). Gestational age ranged between 25 to 42 weeks (mean, 33 weeks). Age at surgery was between 1 to 30 days (mean, 30 days). Preoperatively, 19 patients (51.3%) were on inotropic support and all were intubated and mechanically ventilated. There was no mortality related to surgical procedures. Postoperatively, one patient developed wound infection and disruption. Performing major surgical procedures in the NICU is both feasible and safe. It is useful in very low birth weight, critically ill neonates who have definite risk attached to transfer to the operating room. No special area is needed in the NICU to perform complication-free surgery, but designing an operating room within the NICU will be ideal. (author)

  12. Glucose Regulation and Cognitive Function after Bariatric Surgery

    Galioto, Rachel; Alosco, Michael L.; Spitznagel, Mary Beth; Strain, Gladys; Devlin, Michael; Cohen, Ronald; Crosby, Ross D.; Mitchell, James E.; Gunstad, John


    Introduction Obesity is associated with cognitive impairment and bariatric surgery has been shown to improve cognitive functioning. Rapid improvements in glycemic control are common after bariatric surgery and likely contribute to these cognitive gains. We examined whether improvements in glucose regulation are associated with better cognitive function following bariatric surgery. Method A total of 85 adult bariatric surgery patients underwent computerized cognitive testing and fasting blood draw for glucose, insulin, and glycated hemoglobin (HbA1c) at baseline and 12 month post-operatively. Results Significant improvements in both cognitive function and glycemic control were observed among patients. After controlling for and baseline factors, 12-month homeostatic model assessment of insulin resistance HOMA-IR predicted 12-month digits backward (β = −.253, p < .05), switching of attention- A (β = .156, p < .05), and switching of attention-B (β = −.181, p < .05). Specifically, as HOMA-IR decreased over time, working memory, psychomotor speed, and cognitive flexibility improved. Decreases in HbA1c were not associated with post-operative cognitive improvements. After controlling for baseline cognitive test performance, changes in BMI were also not associated with 12-month cognitive function. Conclusions Small effects of improved glycemic control on improved aspects of attention and executive function were observed following bariatric surgery among severely obese individuals. Future research is needed to identify the underlying mechanisms for the neurocognitive benefits of these procedures. PMID:25875124

  13. A psychiatric perspective view of bariatric surgery patients

    Isabel Brandão


    Full Text Available Abstract Background Bariatric surgery is the only procedure that has significant results in weight loss and improvements in medical comorbidities in morbid obese patients. Severely obese patients are also associated with a higher prevalence of psychiatric disorders and poor quality of life. Objective To evaluate specific areas of psychopathology in individuals undergoing bariatric surgery. Methods A review of the literature was conducted from January 2002 to March 2014 by researching PubMed database using the following query: “morbid AND obesity AND bariatric AND surgery AND (psychiatry OR psychology”. Results Overall improvements in eating behaviors, mood disorders and body image are reported after bariatric surgery, and the mechanism is not enlightened. Risk of suicide and consumption of substances of abuse, especially alcohol, after gastric bypass surgery are problems that clinicians must be aware. Discussion Bariatric patients should be monitored after surgery to identify who did not show the expected benefits postoperatively and the ones who develop psychiatric symptoms after an initial positive response.

  14. Surgical reconstruction of pressure ulcer defects: a single- or two-stage procedure?

    Laing, Tereze A


    BACKGROUND: The surgical management of pressure ulcers traditionally involved staged procedures, with initial debridement of necrotic or infected material followed by reconstruction at a later date when the wound was deemed viable and free of gross infection. However, over the past decade, it has been suggested that a single-stage procedure, combining initial debridement and definitive reconstruction, may provide advantages over staged surgery. We present our experience with the staged approach and review the current evidence for both methods. SUBJECTS AND SETTINGS: : We reviewed medical records of all patients referred to our service for pressure ulcer management between October 2001 and October 2007. The National Rehabilitation Hospital is the national center in Ireland for primary rehabilitation of adults and children suffering from spinal and brain injury, serving patients locally and from around the country. METHODS: All subjects who were managed surgically underwent a 2-stage procedure, with initial debridement and subsequent reconstruction. The main outcome measures were length of hospital stay, postoperative morbidity and mortality, and time to complete ulcer healing. RESULTS: Forty-one of 108 patients with 58 pressure ulcers were managed surgically. All patients underwent initial surgical debridement and 20 patients underwent subsequent pressure ulcer reconstruction. Postreconstructive complications occurred in 5 patients (20%). The mean time to complete ulcer healing was 17.4 weeks. Partial flap necrosis occurred in 3 patients, but there were no episodes of flap failure. CONCLUSIONS: We achieved favorable results with a 2-stage reconstruction technique and suggest that the paucity of evidence related to single-stage procedures does not support a change in surgical management.

  17. Traumatic Extensor Tendon Injuries to the Hand: Clinical Anatomy, Biomechanics, and Surgical Procedure Review.

    Colzani, Giulia; Tos, Pierluigi; Battiston, Bruno; Merolla, Giovanni; Porcellini, Giuseppe; Artiaco, Stefano


    The extensor apparatus is a complex muscle-tendon system that requires integrity or optimal reconstruction to preserve hand function. Anatomical knowledge and the understanding of physiopathology of extensor tendons are essential for an accurate diagnosis of extensor tendon injuries (ETIs) of the hand and wrist, because these lesions are complex and commonly observed in clinical practice. A careful clinical history and assessment still remain the first step for the diagnosis, followed by US and MR to confirm the suspect of ETI or to investigate some doubtful conditions and rule out associate lesions. During last decades the evolution of surgical techniques and rehabilitative treatment protocol led to gradual improvement in clinical results of ETI treatment and surgical repair. Injury classification into anatomical zones and the evaluation of the characteristics of the lesions are considered key points to select the appropriate treatment for ETI. Both conservative and surgical management can be indicated in ETI, depending on the anatomical zone and on the characteristics of the injuries. As a general rule, an attempt of conservative treatment should be performed when the lesion is expected to have favorable result with nonoperative procedure. Many surgical techniques have been proposed over the time and with favorable results if the tendon injury is not underestimated and adequately treated. Despite recent research findings, a lack of evidence-based knowledge is still observed in surgical treatment and postoperative management of ETI. Further clinical and biomechanical investigations would be advisable to clarify this complex issue. PMID:27616821

  18. Control of bleeding in surgical procedures: critical appraisal of HEMOPATCH (Sealing Hemostat

    Lewis KM


    Full Text Available Kevin Michael Lewis,1 Carl Erik Kuntze,2 Heinz Gulle3 1Preclinical Safety and Efficacy, Baxter Healthcare Corporation, Deerfield, IL, USA; 2Medical Affairs, Baxter Healthcare SA, Zurich, Switzerland; 3Surgical Sciences and Engineering, Baxter Medical Products GmbH, Vienna, Austria Abstract: The need for advanced hemostatic agents increases with the complexity of surgical procedures and use of anticoagulation and antiplatelet treatments. HEMOPATCH (Sealing Hemostat is a novel, advanced hemostatic pad that is composed of a synthetic, protein-reactive monomer and a collagen backing. The active side is covered with a protein-reactive monomer: N-hydroxysuccinimide functionalized polyethylene glycol (NHS-PEG. NHS-PEG rapidly affixes the collagen pad to tissue to promote and maintain hemostasis. The combined action of the NHS-PEG and collagen is demonstrated to have benefit relative to other hemostatic agents in surgery and preclinical surgical models. This paper reviews the published investigations and case reports of the hemostatic efficacy of HEMOPATCH, wherein HEMOPATCH is demonstrated to be an effective, easy-to-use hemostatic agent in open and minimally invasive surgery of patients with thrombin- or platelet-induced coagulopathies.

  19. Peripheral nerve injuries resulting from common surgical procedures in the lower portion of the abdomen.

    Stulz, P; Pfeiffer, K M


    Twenty-three patients had a painful ilioinguinal and/or iliohypogastric nerve entrapment syndrome following common surgical procedures in the lower portion of the abdomen (appendectomy, repair of inguinal hernia, and gynecologic procedures through transverse incision). The diagnostic triad of nerve entrapment after operation comprises (1) typical burning or lancinating pain near the incision that radiates to the area supplied by the nerve, (2) clear evidence of impaired sensory perception of the nerve, and (3) pain relieved by infiltration with anesthetic for local effects at the site where the two nerves leave the internal oblique muscle. Surgical repair of the scar with resection of the compromised nerve is the most effective treatment. Sixteen patients became symptom free after neurectomy, seven still suffer chronic pain in the scar. PMID:7065874

  20. The Perception of Aversiveness of Surgical Procedure Pictures Is Modulated by Personal/Occupational Relevance.

    Paes, Juliana; de Oliveira, Leticia; Pereira, Mirtes Garcia; David, Isabel; Souza, Gabriela Guerra Leal; Sobral, Ana Paula; Machado-Pinheiro, Walter; Mocaiber, Izabela


    It is well established that emotions are organized around two motivational systems: the defensive and the appetitive. Individual differences are relevant factors in emotional reactions, making them more flexible and less stereotyped. There is evidence that health professionals have lower emotional reactivity when viewing scenes of situations involving pain. The objective of this study was to investigate whether the rating of pictures of surgical procedure depends on their personal/occupational relevance. Fifty-two female Nursing (health discipline) and forty-eight Social Work (social science discipline) students participated in the experiment, which consisted of the presentation of 105 images of different categories (e.g., neutral, food), including 25 images of surgical procedure. Volunteers judged each picture according to its valence (pleasantness) and arousal using the Self-Assessment Manikin scale (dimensional approach). Additionally, the participants chose the word that best described what they felt while viewing each image (discrete emotion perspective). The average valence score for surgical procedure pictures for the Nursing group (M = 4.57; SD = 1.02) was higher than the score for the Social Work group (M = 3.31; SD = 1.05), indicating that Nursing students classified those images as less unpleasant than the Social Work students did. Additionally, the majority of Nursing students (65.4%) chose "neutral" as the word that best described what they felt while viewing the pictures. In the Social Work group, disgust (54.2%) was the emotion that was most frequently chosen. The evaluation of emotional stimuli differed according to the groups' personal/occupational relevance: Nursing students judged pictures of surgical procedure as less unpleasant than the Social Work students did, possibly reflecting an emotional regulation skill or some type of habituation that is critically relevant to their future professional work.

  2. Revisional Bariatric/Metabolic Surgery: What Dictates Its Indications?

    Ma, Pearl; Reddy, Subhash; Higa, Kelvin D


    Bariatric/metabolic surgery is currently the only effective long-term treatment for morbid obesity- and obesity-related diseases such as diabetes, heart disease, hypertension, obstructive sleep apnea, and dyslipidemia. In addition, bariatric/metabolic surgery has been shown to significantly reduce the incidence of diabetes and cancer and prolong life when compared to non-surgical therapies. However, as obesity is a chronic disease, recidivism of weight and comorbid conditions can occur. In addition, the surgical construct can lead to long-term consequences such as marginal ulceration, bowel obstruction, reflux, and nutritional deficiencies. Despite these drawbacks, prospective randomized controlled studies and long-term longitudinal population-based comparative studies greatly favor surgical intervention as opposed to traditional lifestyle, diet, and exercise programs. Revisional surgery can be quite complex and technically challenging and may offer the patient a wide variety of solutions for treatment of weight recidivism and complications after primary operations. Given the paucity of high quality published data, we have endeavored to provide indications for revisions after bariatric surgery. PMID:27221504

  3. Endoscopic extraction of adjustable gastric bands after intragastric migration as a complication of bariatric surgery: technique and advice

    Collado-Pacheco, David; Rábago-Torre, Luis Ramon; Arias-Rivera, Maria; Ortega-Carbonel, Alejandro; Olivares-Valles, Ana; Alonso-Prada, Alicia; Vázquez-Echarri, Jaime; Herrera-Merino, Norberto


    Background: Surgery has been the method most widely used to manage the extraction of gastric bands with inclusion as a late complication of bariatric surgery; however, surgical extraction entails morbidity and limits future surgical procedures. The development of endoscopic techniques has provided an important means of improving the treatment of this complication, enabling minimally invasive and safe procedures that have a high success rate. Methods: A retrospective analysis was conducted of patients who had laparoscopic gastric banding complicated by intragastric migration and were treated endoscopically. A technique already described for managing this complication was employed. An MTW Endoskopie Dormia basket for mechanical lithotripsy or a standard 0.0035-in guidewire was placed around the band, and an MTW Endoskopie emergency lithotripter was used to section it, after which the band was extracted with a standard polypectomy snare. Also analyzed were the initial symptoms of patients with this complication, the mean time from surgery to development of the event, the success rate of endoscopic treatment, and complications, Results: A total of 127 patients had undergone gastric banding surgery in our Bariatric Surgery Center; of these, 12 patients (9.4 %) developed a complication such as intragastric migration of the band. Weight gain and pain were the main symptoms in 11 patients (92 %), and the mean time to the development of symptoms was 51.3 months. A single endoscopic treatment was successful in 7 of 9 patients (78 %). Only 1 complication, involving ventilation during anesthesia, occurred; no other adverse events were recorded. Conclusions: The endoscopic extraction of bands with inclusion is feasible and can be performed easily and successfully. The procedure is available in all hospitals and has a low incidence of related complications, so that unnecessary surgical procedures can be avoided.

    Full Text Available Salvatore Giordano,1 Mikael Victorzon2,3 1Department of Plastic and General Surgery, Turku University Hospital, Turku, 2Department of Gastrointestinal Surgery, Vaasa Central Hospital, Vaasa, 3University of Turku, Turku, Finland Abstract: Controversy exists regarding the effectiveness and safety of bariatric/metabolic surgery in elderly patients. We performed a systematic review on this issue in patients aged 60 years or older. MEDLINE, Cochrane Library, Embase, Scopus, and Google Scholar were searched until August 2015 for studies on outcomes of bariatric surgery in elderly patients. The results were expressed as pooled proportions (% with 95% confidence intervals. Heterogeneity across the studies was evaluated by the I2 test, and a random-effects model was used. Twenty-six articles encompassing 8,149 patients were pertinent with this issue and included data on bariatric surgery outcomes in elderly population. Fourteen patients died during the 30-day postoperative period, with a pooled mortality of 0.01%. Pooled overall complication rate was 14.7%. At 1-year follow-up, pooled mean excess weight loss was 53.77%, pooled diabetes resolution was 54.5%, and pooled hypertension resolution was 42.5%, while pooled lipid disorder resolution was 41.2%. Outcomes and complication rates of bariatric surgery in patients older than 60 years are comparable to those in a younger population, independent of the type of procedure performed. Patients should not be denied bariatric surgery because of their age alone. Keywords: morbid obesity, bariatric surgery, elderly, gastric bypass, weight loss, laparoscopy

  5. Effect of the Prolonged Inspiratory to Expiratory Ratio on Oxygenation and Respiratory Mechanics During Surgical Procedures.

    Park, Jin Ha; Lee, Jong Seok; Lee, Jae Hoon; Shin, Seokyung; Min, Nar Hyun; Kim, Min-Soo


    Prolonged inspiratory to expiratory (I:E) ratio ventilation has been researched to reduce lung injury and improve oxygenation in surgical patients with one-lung ventilation (OLV) or carbon dioxide (CO2) pneumoperitoneum. We aimed to confirm the efficacy of the 1:1 equal ratio ventilation (ERV) compared with the 1:2 conventional ratio ventilation (CRV) during surgical procedures. Electronic databases, including PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, and Google Scholar were searched.Prospective interventional trials that assessed the effects of prolonged I:E ratio of 1:1 during surgical procedures. Adult patients undergoing OLV or CO2 pneumoperitoneum as specific interventions depending on surgical procedures. The included studies were examined with the Cochrane Collaboration's tool. The data regarding intraoperative oxygenation and respiratory mechanics were extracted, and then pooled with standardized mean difference (SMD) using the method of Hedges. Seven trials (498 total patients, 274 with ERV) were included. From overall analysis, ERV did not improve oxygenation at 20 or 30 minutes after specific interventions (SMD 0.193, 95% confidence interval (CI): -0.094 to 0.481, P = 0.188). From subgroup analyses, ERV provided significantly improved oxygenation only with laparoscopy (SMD 0.425, 95% CI: 0.167-0.682, P = 0.001). At 60 minutes after the specific interventions, ERV improved oxygenation significantly in the overall analysis (SMD 0.447, 95% CI: 0.209-0.685, P reduce the Ppeak and Pplat. PMID:27043700

  6. Bariatric surgery in hypothalamic obesity

    Nathan eBingham


    Full Text Available Craniopharyngiomas (CP are epithelial neoplasms generally found in the area of the pituitary and hypothalamus. Despite benign histology, these tumors and/or their treatment often result in significant, debilitating disorders of endocrine, neurological, behavioral, and metabolic systems. Severe obesity is observed in a high percentage of patients with CP resulting in significant comorbidities and negatively impacting quality of life. Obesity occurs as a result of hypothalamic damage and disruption of normal homeostatic mechanisms regulating energy balance. Such pathological weight gain, termed hypothalamic obesity (HyOb, is often severe and refractory to therapy.Unfortunately, neither lifestyle intervention nor pharmacotherapy has proven truly effective in the treatment of CP-HyOb. Given the limited choices and poor results of these treatments, several groups have examined bariatric surgery as a treatment alternative for patients with CP-HyOb. While a large body of evidence exists supporting the use of bariatric surgery in the treatment of exogenous obesity and its comorbidities, its role in the treatment of HyOb has yet to be well defined. To date, the existing literature on bariatric surgery in CP-HyOb is largely limited to case reports and series with short term follow-up. Here we review the current reports on the use of bariatric surgery in the treatment of CP-HyOb. We also compare these results to those reported for other populations of HyOb, including Prader-Willi Syndrome and patients with melanocortin signaling defects. While initial reports of bariatric surgery in CP-HyOb are promising, their limited scope makes it difficult to draw any substantial conclusions as to the long term safety and efficacy of bariatric surgery in CP-HyOb. There continues to be a need for more robust, controlled, prospective trials with long term follow-up in order to better define the role of bariatric surgery in the treatment of all types of hypothalamic

OBJECTIVES: To compare the isokinetic shoulder performance after surgical treatment to that after non-surgical treatment for pectoralis major muscle rupture. METHODS: We assessed 33 pectoralis major muscle ruptures (18 treated non-surgically and 15 treated surgically. Horizontal abduction and adduction as well as external and internal rotation at 60 and 120 degrees/s were tested in both upper limbs. Peak torque, total work, contralateral deficiency, and the peak torque agonist-to-antagonist ratio were measured. RESULTS: Contralateral muscular deficiency did not differ between the surgical and non-surgical treatment modalities. However, the surgical group presented twice the number of athletes with clinically acceptable contralateral deficiency (<20% for internal rotators compared to the non-surgical group. The peak torque ratio between the external and internal rotator muscles revealed a similar deficit of the external rotation in both groups and on both sides (surgical, 61.60% and 57.80% and non-surgical, 62.06% and 54.06%, for the dominant and non-dominant sides, respectively. The peak torque ratio revealed that the horizontal adduction muscles on the injured side showed similar weakness in both groups (surgical, 86.27%; non-surgical, 98.61%. CONCLUSIONS: This study included the largest single series of athletes reported to date for this type of injury. A comparative analysis of muscular strength and balance showed no differences between the treatment modalities for pectoralis major muscle rupture. However, the number of significant clinical deficiencies was lower in the surgical group than in the non-surgical group, and both treatment modalities require greater attention to the rehabilitation process, especially for the recovery of muscle strength and balance.

  8. [A new concept in digestive surgery: the computer assisted surgical procedure, from virtual reality to telemanipulation].

    Marescaux, J; Clément, J M; Nord, M; Russier, Y; Tassetti, V; Mutter, D; Cotin, S; Ayache, N


    Surgical simulation increasingly appears to be an essential aspect of tomorrow's surgery. The development of a hepatic surgery simulator is an advanced concept calling for a new writing system which will transform the medical world: virtual reality. Virtual reality extends the perception of our five senses by representing more than the real state of things by the means of computer sciences and robotics. It consists of three concepts: immersion, navigation and interaction. Three reasons have led us to develop this simulator: the first is to provide the surgeon with a comprehensive visualisation of the organ. The second reason is to allow for planning and surgical simulation that could be compared with the detailed flight-plan for a commercial jet pilot. The third lies in the fact that virtual reality is an integrated part of the concept of computer assisted surgical procedure. The project consists of a sophisticated simulator which has to include five requirements: visual fidelity, interactivity, physical properties, physiological properties, sensory input and output. In this report we will describe how to get a realistic 3D model of the liver from bi-dimensional 2D medical images for anatomical and surgical training. The introduction of a tumor and the consequent planning and virtual resection is also described, as are force feedback and real-time interaction. PMID:9554121

  9. Bariatric surgery and pregnancy: literature review

    Pedro Ferrand Miranda


    Full Text Available Obesity has currently reached epidemic proportions, both in Chile and in the world. This condition is associated to a variety of maternal complications in all stages of the vital cycle and during pregnancy. Medical treatment has not proved successful thus resulting in an increase in bariatric surgery in recent years, even when it is not first line treatment. This literature review aims to report updated results of surgical treatment for obesity before and during pregnancy with respect to fertility, gestational diabetes, pre-eclampsia and pregnancy-induced hypertension. It also looks into the possible effects of surgery on fetal development, and its relation to premature delivery, fetal macrosomy, low birth weight and neural tube defects, as well as effects on maternal and fetal outcomes, mainly in nutrition. Lastly, we suggest some recommendations that arise from this review on the role of contraception, nutrition and time between surgery and pregnancy.

    Objective: The purpose of this study was to evaluate compliance with guidelines in surgical prophylaxis (SP) procedures in Turkey. Materials and Methods: A point prevalence study involving 4 university, 5 education and research and 7 public hospitals was performed assessing compliance with guidelines for antibiotic use in SP. Compliance was based on the “Clinical Practice Guidelines for Antimicrobial Surgery (CPGAS) 2013” guideline. Results: Sixteen centers were included in the study, with 166 operations performed at these being evaluated. Parenteral antibiotic for SP was applied in 161 (96.9%) of these. Type of antibiotic was inappropriate in 66 (40.9%) cases and duration of use in 47 (29.1%). The main antibiotics used inappropriately in SP were ceftriaxone, glycopeptides and aminoglycosides. No significant difference was observed between secondary and tertiary hospitals in terms of inappropriate selection. Duration of prophylaxis was also incompatible with guideline recommendations in approximately half of surgical procedures performed in both secondary and tertiary hospitals, however statistical significance was observed between institutions in favor of tertiary hospitals. Conclusion: Antibiotics are to a considerable extent used in a manner incompatible with guidelines even in tertiary hospitals in Turkey. It must not be forgotten that several pre-, intra- and postoperative factors can be involved in the development of surgical site infections (SSI), and antibiotics are not the only option available for preventing these. A significant improvement can be achieved in prophylaxis with close observation, educational activities, collaboration with the surgical team and increasing compliance with guidelines. All health institutions must establish and apply their own SP consensus accompanied by the guidelines in order to achieve success in SP. PMID:27026760

  12. Anesthetic issues and perioperative blood pressure management in patients who have cerebrovascular diseases undergoing surgical procedures.

    Jellish, W Scott


    Patients who have cerebrovascular disease and vascular insufficiency routinely have neurosurgical and nonneurosurgical procedures. Anesthetic priorities must provide a still bloodless operative field while maintaining cardiovascular stability and renal function. Patients who have symptoms or a history of cerebrovascular disease are at increased risk for stroke, cerebral hypoperfusion, and cerebral anoxia. Type of surgery and cardiovascular status are key concerns when considering neuroprotective strategies. Optimization of current condition is important for a good outcome; risks must be weighed against perceived benefits in protecting neurons. Anesthetic use and physiologic manipulations can reduce neurologic injury and assure safe and effective surgical care when cerebral hypoperfusion is a real and significant risk. PMID:16935193

    Full Text Available Min Zhou, Dian Huang, Chen Liu, Zhao Liu, Min Zhang, Tong Qiao, Chang-Jian Liu Department of Vascular Surgery, Affiliated Drum Tower Hospital of Nanjing University Medical School, Nanjing, People’s Republic of China Objective: To compare outcomes of hybrid (combined surgical and endovascular procedures (HYBRID with open surgical reconstructions (OPEN in patients with multilevel infrainguinal artery occlusive diseases. Design: Case series study with retrospective analysis of prospectively collected nonrandomized data.Methods: Between 2008 and 2012, 64 patients underwent OPEN and 43 underwent HYBRID. Patient characteristics, technique success, clinical improvement, and procedure-related morbidity were reviewed and compared. Patency rates and limb salvages were analyzed and compared using Kaplan–Meier life tables. Cox regression analyses were used to assess the influence of various risk factors on primary patency.Results: HYBRID patients were older and presented with worse New York Heart Association function compared with OPEN patients. The increase in the ankle-brachial index and improvement of Ruthford category after procedures were equivalent between two groups, but HYBRID patients had shorter hospital length of stay (7.6±12.0 versus 15.5±17.3; P= 0.018 and less overall perioperative morbidity (12% versus 28%; P=0.042 compared with OPEN patients. No statistically significant difference in 36-month primary (47.1%±7.1% versus 50.1%±9.4%; P=0.418, assisted primary (57.0%±7.9% versus 62.4%±9.2%; P=0.517, or secondary (82.0%±6.8% versus 83.1%±7.3%; P=0.445 patency was seen between the two groups. Limb salvage rates of HYBRID vs OPEN at 3 years were similar (76.3%±9.3% versus 80.4%±8.2%; P=0.579. Critical limb ischemia was a negative predictor of long-term patency of patients in both the HYBRID and OPEN groups (P=0.012 and P<0.001, respectively, and the presence of diabetes and renal insufficiency were another two independent predictors

  14. Gastrointestinal changes after bariatric surgery.

    Quercia, I; Dutia, R; Kotler, D P; Belsley, S; Laferrère, B


    Severe obesity is a preeminent health care problem that impacts overall health and survival. The most effective treatment for severe obesity is bariatric surgery, an intervention that not only maintains long-term weight loss but also is associated with improvement or remission of several comorbidies including type 2 diabetes mellitus. Some weight loss surgeries modify the gastrointestinal anatomy and physiology, including the secretions and actions of gut peptides. This review describes how bariatric surgery alters the patterns of gastrointestinal motility, nutrient digestion and absorption, gut peptide release, bile acids and the gut microflora, and how these changes alter energy homeostasis and glucose metabolism.

  15. The Alberta population-based prospective evaluation of the quality of life outcomes and economic impact of bariatric surgery (APPLES study: background, design and rationale

    McCargar Linda


    Full Text Available Abstract Background Extreme obesity affects nearly 8% of Canadians, and is debilitating, costly and ultimately lethal. Bariatric surgery is currently the most effective treatment available; is associated with reductions in morbidity/mortality, improvements in quality of life; and appears cost-effective. However, current demand for surgery in Canada outstrips capacity by at least 1000-fold, causing exponential increases in already protracted, multi-year wait-times. The objectives and hypotheses of this study were as follows: 1. To serially assess the clinical, economic and humanistic outcomes in patients wait-listed for bariatric care over a 2-year period. We hypothesize deterioration in these outcomes over time; 2. To determine the clinical effectiveness and changes in quality of life associated with modern bariatric procedures compared with medically treated and wait-listed controls over 2 years. We hypothesize that surgery will markedly reduce weight, decrease the need for unplanned medical care, and increase quality of life; 3. To conduct a 3-year (1 year retrospective and 2 year prospective economic assessment of bariatric surgery compared to medical and wait-listed controls from the societal, public payor, and health-care payor perspectives. We hypothesize that lower indirect, out of pocket and productivity costs will offset increased direct health-care costs resulting in lower total costs for bariatric surgery. Methods/design Population-based prospective cohort study of 500 consecutive, consenting adults, including 150 surgically treated patients, 200 medically treated patients and 150 wait-listed patients. Subjects will be enrolled from the Edmonton Weight Wise Regional Obesity Program (Edmonton, Alberta, Canada, with prospective bi-annual follow-up for 2 years. Mixed methods data collection, linking primary data to provincial administrative databases will be employed. Major outcomes include generic, obesity-specific and preference

  16. Potential mechanisms mediating improved glycemic control after bariatric/metabolic surgery.

    Yamamoto, Hiroshi; Kaida, Sachiko; Yamaguchi, Tsuyoshi; Murata, Satoshi; Tani, Masaji; Tani, Tohru


    Conservative medical treatment for morbid obesity generally fails to sustain weight loss. On the other hand, surgical operations, so-called bariatric surgery, have evolved due to their long-term effects. The global increase in the overweight population and the introduction of laparoscopic surgery have resulted in the use of bariatric surgery spreading quickly worldwide in recent years. Recent clinical evidence suggests that bariatric surgery not only reduces body weight, but also improves secondary serious diseases, including type 2 diabetes mellitus, in so-called metabolic surgery. Moreover, several potential mechanisms mediating the improvement in glycemic control after bariatric/metabolic surgery have been proposed based on the animal and human studies. These mechanisms include changes in the levels of gastrointestinal hormones, bacterial flora, bile acids, intestinal gluconeogenesis and gastrointestinal motility as well as adipose tissue and inflammatory mediators after surgery. The mechanisms underlying improved glycemic control are expected to accelerate the promotion of both metabolic and bariatric surgery. This article describes the current status of bariatric surgery worldwide and in Japan, reviews the accumulated data for weight loss and diabetic improvements after surgery and discusses the potential mechanisms mediating improved glycemic control.

  17. Automating Data Abstraction in a Quality Improvement Platform for Surgical and Interventional Procedures

    Yetisgen, Meliha; Klassen, Prescott; Tarczy-Hornoch, Peter


    Objective: This paper describes a text processing system designed to automate the manual data abstraction process in a quality improvement (QI) program. The Surgical Care and Outcomes Assessment Program (SCOAP) is a clinician-led, statewide performance benchmarking QI platform for surgical and interventional procedures. The data elements abstracted as part of this program cover a wide range of clinical information from patient medical history to details of surgical interventions. Methods: Statistical and rule-based extractors were developed to automatically abstract data elements. A preprocessing pipeline was created to chunk free-text notes into its sections, sentences, and tokens. The information extracted in this preprocessing step was used by the statistical and rule-based extractors as features. Findings: Performance results for 25 extractors (14 statistical, 11 rule based) are presented. The average f1-scores for 11 rule-based extractors and 14 statistical extractors are 0.785 (min=0.576,max=0.931,std-dev=0.113) and 0.812 (min=0.571,max=0.993,std-dev=0.135) respectively. Discussion: Our error analysis revealed that most extraction errors were due either to data imbalance in the data set or the way the gold standard had been created. Conclusion: As future work, more experiments will be conducted with a more comprehensive data set from multiple institutions contributing to the QI project. PMID:25848598

  18. Bariatric diagnostic CT scanning: A radiotherapy perspective

    Obesity is increasing in the United Kingdom. Equipment available for this patient group including wheelchairs, beds and hoists is becoming more common in the hospital environment; diagnostic imaging equipment that can accommodate bariatric patients has not increased at the same rate. Subsequently these service-users are often unable to receive “gold-standard” cross-sectional imaging within their patient-pathway. This paper highlights how a diagnostic imaging department has utilised wide-bore CT scanning equipment within the radiotherapy setting to ensure an equitable service for all service users. Through literature review and local experience, a standard operating procedure and scanning service has been developed. Areas explored include technical consideration of scanner design; patient positioning; image artefacts and intravenous contrast administration. Also investigated is patient wellbeing incorporating manual handling, respiration and psycho-social needs. Additionally, demonstration of how interprofessional collaboration by diagnostic and radiotherapy radiographers can ensure the best imaging experience and outcome for this patient group. - Highlights: • Rising obesity in the UK has highlighted a shortage of diagnostic imaging facilities. • Large bore CT scanners are the scanner of choice for radiotherapy planning. • Technical capability, manual handling and psycho-social issues have been explored. • Bariatric diagnostic imaging facilitated by inter-professional collaboration

  20. A review of psychological assessment instruments for use in bariatric surgery evaluations.

    Marek, Ryan J; Heinberg, Leslie J; Lavery, Megan; Merrell Rish, Julie; Ashton, Kathleen


    Bariatric surgery is a viable treatment option for patients with extreme obesity and associated medical comorbidities; however, optimal surgical outcomes are not universal. Surgical societies, such as the American Society for Metabolic and Bariatric Surgery (ASMBS), recommend that patients undergo a presurgical psychological evaluation that includes reviewing patients' medical charts, conducting a comprehensive clinical interview, and employing some form of objective psychometric testing. Despite numerous societies recommending the inclusion of self-report assessments, only about 2/3 of clinics actively use psychological testing-some of which have limited empirical support to justify their use. This review aims to critically evaluate the psychometric properties of self-report measures when used in bariatric surgery settings and provide recommendations to help guide clinicians in selecting instruments to use in bariatric surgery evaluations. Recommended assessment batteries include use of a broadband instrument along with a narrowband eating measure. Suggestions for self-report measures to include in a presurgical psychological evaluation in bariatric surgery settings are also provided. (PsycINFO Database Record PMID:27537008

  2. Evaluation of medical and health economic effectiveness of bariatric surgery (obesity surgery versus conservative strategies in adult patients with morbid obesity

    von der Schulenburg, Johann-Matthias


    Full Text Available Background: Obesity with its associated medical, psychological, social, and economic complications is considered a chronic, multifactorial disorder. Given the magnitude of the challenge obesity, there is a clear need for preventive as well as therapeutic measures and strategies on an individual and a public health level. Objectives: The goal of this health technology assessment (HTA-report is to summarise the current literature on bariatric surgery, to evaluate their medical effectiveness/efficacy and cost-effectiveness as well as the ethical, social and legal implications of these procedures in comparison to conventional therapies and compared to each other. Methods: Relevant publications are identified by means of a structured search of databases accessed on 13.11.2006 and an update conducted on 12.11.2007. In addition, a manual search of identified reference lists is conducted. The present report includes German and English literature published since 2001 and targeting adult subjects with morbid obesity (body mass index (BMI >=40 kg/m² or BMI >=35 kg/m² with severe comorbidities. The methodological quality of studies included is assessed according to pre-defined quality criteria by two independent scientists. Results: Among 5910 retrieved publications, 25 medical articles, as well as seven health economic studies meet the inclusion criteria. The medical studies show a superior weight loss following bariatric surgery compared to conventional therapy. Malabsorptive procedures lead to a more profound weight loss than purely restrictive procedures. Weight reduction in general is accompanied by a reduced frequency of comorbidities (mostly diabetes type 2. The evidence is not sufficient to quantify these effects for individual procedures or to assess long-term outcomes. However, recent studies show a profound survival benefit for surgically treated patients up to a period of eleven years. The economic studies illustrate that bariatric surgery is

Objective: To compare the outcomes of health care resource utilization (HRU and costs associated with using ORCs compared to other adjunctive hemostats (OAHs are defined as flowables, gelatins, and topical thrombins for surgical procedures in the US inpatient setting. Patients and methods: A retrospective, US-based cohort study was conducted using hospital inpatient discharges from the 2011–2012 calendar years in the Premier Healthcare Database. Patients with either an ORC or an OAH who underwent a cardiovascular procedure (valve surgery and/or coronary artery bypass graft surgery, carotid endarterectomy, cholecystectomy, or hysterectomy were included. Propensity score matching was used to create comparable groups of ORC and OAH patients. Clinical, economic, and HRU outcomes were compared. Results: The propensity score matching created balanced patient cohorts for cardiovascular procedure (22,718 patients, carotid endarterectomy (10,890 patients, cholecystectomy (6,090 patients, and hysterectomy (9,348 patients. In all procedures, hemostatic agent costs were 28%–56% lower for ORCs, and mean hemostat units per discharge were 16%–41% lower for ORCs compared to OAHs. Length of stay and total procedure costs for patients treated with ORCs were lower for carotid endarterectomy patients (0.3 days and US$700 and for cholecystectomy patients


    G. Silecchia


    Full Text Available The incidence of type II diabetes mellitus (T2DM is increasing in all the world. In this way the comorbidities and complications of the T2DM as well as death related T2DM are also increasing. It was demonstrated by many studies that T2DM is a medically incurable disease, chronic and progressive, and despite all the medical therapy and life style changing, more than 20% from the patients have a poor glycemic control. On the other hand, some surgical procedures, initially performed for morbid obesity (bariatric surgery revealed good results to control the diabetes and even the metabolic syndrome. This paper presents the advantages and disadvantages of three main surgical procedures: gastric by-pass, sleeve gastrectomy and gastric banding. All of these procedures are very effectiveness to control the diabetes and metabolic syndrome. Further studies are necessary to establish the guidelines for the treatment (and even prophylaxis of T2DM.

  6. Interventional radiological procedures in impaired function of surgically implanted catheter-port systems

    Purpose: System-related complications in surgically implanted catheter-port systems (CPS) for intraarterial (i.a.) chemotherapy are well known. In most cases of complications, the treatment must be interrupted and the catheter-port system must be repaired surgically. We describe microinvasive interventional radiological procedures to correct some dysfunctions of CPS.Methods: Five patients with repetitive dysfunction of CPS were treated with interventional techniques. Two patients presented with perfusion impairment, one patient had a pseudoaneurysm of the hepatic artery, and two patients presented with catheter displacement. Radiological interventions included mechanical recanalization with a guidewire, vascular stenting, and correction of catheter dislocation with a gooseneck snare.Results: In all cases, correct function of the CPS was restored. No intervention-related complications occurred and surgery was avoided. Chemotherapy could be continued for a period of 4-10 months.Conclusion: For some system-related complications, minimally invasive radiological interventions can be used to restore the function of CPS for i.a. chemotherapy.

  9. Influence of perioperative administration of amino acids on thermoregulation response in patients underwent colorectal surgical procedures

    Zeba Snježana


    Full Text Available Background. Hypothermia in the surgical patients can be the consequence of long duration of surgical intervention, general anesthesia and low temperature in operating room. Postoperative hypothermia contributes to a number of postoperative complications such as arrhythmia, myocardial ischemia, hypertension, bleeding, wound infection, coagulopathy, prolonged effect of muscle relaxants. External heating procedures are used to prevent this condition, but some investigations reported that infusion of aminoacids during surgery can induce thermogenesis and prevent postoperative hypothermia. Case report. We reported two males who underwent major colorectal surgery for rectal carcinoma. One patient received Aminosol 15% solution, 125 ml/h, while the other did not. The esophageal temperatures in both cases were measured every 30 minutes during the operation and 60 minutes after in Intensive Care Unit. We were monitoring blood pressure, heart rate, ECG, and shivering. Patient who received aminoacids showed ameliorated postoperative hypothermia without hypertension, arrhythmia, or shivering, while the other showed all symptoms mentioned above. Conclusion. According to literature data, as well as our findings, we can conclude that intraoperative intravenous treatment with amino acid solution ameliorates postoperative hypothermia along with its complications. .

  14. Bariatric surgery and nonalcoholic fatty liver disease: current and potential future treatments

    Akira eSasaki


    Full Text Available Nonalcoholic fatty liver disease (NAFLD and nonalcoholic steatohepatitis (NASH are increasingly common cause of chronic liver disease worldwide. The diagnosis of NASH is challenging as most affected patients are symptom-free and the role of routine screening is not clearly established. Most patients with severe obesity who undergo bariatric surgery have NAFLD, which is associated insulin resistance, type 2 diabetes mellitus (T2DM, hypertension, and obesity-related dyslipidemia. The effective treatment for NAFLD is weight reduction through lifestyle modifications, antiobesity medication, or bariatric surgery. Among these treatments, bariatric surgery is the most reliable method for achieving substantial, sustained weight loss. This procedure is safe when performed by a skilled surgeon, and the benefits include reduced weight, improved quality of life, decreased obesity-related comorbidities, and increased life expectancy. Further research is urgently needed to determine the best use of bariatric surgery with NAFLD patients at high risk of developing liver cirrhosis and its role in modulating complications of NAFLD, such as T2DM and cardiovascular disease. The current evidence suggests that bariatric surgery for patients with severe obesity decreases the grade of steatosis, hepatic inflammation, and fibrosis. However, further long-term studies are required to confirm the true effects before recommending bariatric surgery as a potential treatment for nonalcoholic steatohepatitis.

    Thongprayoon, Charat; Cheungpasitporn, Wisit; Vijayvargiya, Priya; Anthanont, Pimjai; Erickson, Stephen B


    Background With rising prevalence of morbid obesity, the number of bariatric surgeries performed each year has been increasing worldwide. The objective of this meta-analysis was to assess the risk of kidney stones following bariatric surgery. Methods A literature search was performed using MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews from inception through July 2015. Only studies reporting relative risks, odd ratios or hazard ratios (HRs) to compare risk of kidney stones in patients who underwent bariatric surgery versus no surgery were included. Pooled risk ratios (RR) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method. Results Four studies (One randomized controlled trial and three cohort studies) with 11,348 patients were included in analysis to assess the risk of kidney stones following bariatric surgery. The pooled RR of kidney stones in patients undergoing bariatric surgery was 1.22 (95% CI, 0.63-2.35). The type of bariatric surgery subgroup analysis demonstrated an increased risk of kidney stones in patients following Roux-en-Y gastric bypass (RYGB) with the pooled RR of 1.73 (95% CI, 1.30-2.30) and a decreased risk of kidney stones in patients following restrictive procedures including laparoscopic banding or sleeve gastrectomy with the pooled RR of 0.37 (95% CI, 0.16-0.85). Conclusions Our meta-analysis demonstrates an association between RYGB and increased risk of kidney stones. Restrictive bariatric surgery, on the other hand, may decrease kidney stone risk. Future study with long-term follow-up data is needed to confirm this potential benefit of restrictive bariatric surgery. PMID:26803902

  16. Bariatric surgery complications. Internal hernia: A potentially fatal condition. A case report and literature review

    In recent years, Obesity (defined as Body Mass Index > 30 kg/m2) has increased its prevalence reaching epidemic levels in countries such as The United States where it has became a national health issue. In Colombia the Obesity prevalence is figured around 14%. Treatment options for Obesity include life style modifications, pharmacologist management and surgical approach (Bariatric Surgery). This article describes a patient with previous bariatric surgery, who presents abdominal pain and melena owed to isquemic process of the alimentary limb caused by an internal hernia which is a potentially lethal condition if it is not highly suspected allowing its early diagnosis and treatment

  17. A standard operating procedure for the surgical implantation of transmitters in juvenile salmonids

    Liedtke, T.L.; Beeman, J.W.; Gee, L.P.


    Biotelemetry is a useful tool to monitor the movements of animals and is widely applied in fisheries research. Radio or acoustic technology can be used, depending on the study design and the environmental conditions in the study area. A broad definition of telemetry also includes the use of Passive Integrated Transponder (PIT) tags, either separately or with a radio or acoustic transmitter. To use telemetry, fish must be equipped with a transmitter. Although there are several attachment procedures available, surgical implantation of transmitters in the abdominal cavity is recognized as the best technique for long-term telemetry studies in general (Stasko and Pincock, 1977; Winter, 1996; Jepsen, 2003), and specifically for juvenile salmonids, Oncorhynchus spp. (Adams and others, 1998a, 1998b; Martinelli and others, 1998; Hall and others, 2009). Studies that use telemetry assume that the processes by which the animals are captured, handled, and tagged, as well as the act of carrying the transmitter, will have minimal effect on their behavior and performance. This assumption, commonly stated as a lack of transmitter effects, must be valid if telemetry studies are to describe accurately the movements and behavior of an entire population of interest, rather than the subset of that population that carries transmitters. This document describes a standard operating procedure (SOP) for surgical implantation of radio or acoustic transmitters in juvenile salmonids. The procedures were developed from a broad base of published information, laboratory experiments, and practical experience in tagging thousands of fish for numerous studies of juvenile salmon movements near Columbia River and Snake River hydroelectric dams. Staff from the Western Fisheries Research Center's Columbia River Research Laboratory (CRRL) frequently have used telemetry studies to evaluate new structures or operations at hydroelectric dams in the Columbia River Basin, and these evaluations typically

  18. ANTIBIOTIC PROPHYLAXIS IN BARIATRIC SURGERY: a continuous infusion of cefazolin versus ampicillin/sulbactam and ertapenem


    Background The incidence of surgical site infection in bariatric patients is significant and the current recommendations for antibiotic prophylaxis are sometimes inadequate. Objective The aim of this study was to analyze the effect of three prophylactic antibiotic regimens on the incidence of surgical site infection. Methods A prospective, cross-sectional study was conducted between January 2009 and January 2013 in which 896 Roux-en-Y gastric bypasses were performed to treat obesity. The stud...

  19. Iron Deficiency and Bariatric Surgery

    Ignacio Jáuregui-Lobera


    It is estimated that the prevalence of anaemia in patients scheduled for bariatric surgery is higher than in the general population and the prevalence of iron deficiencies (with or without anaemia) may be higher as well. After surgery, iron deficiencies and anaemia may occur in a higher percentage of patients, mainly as a consequence of nutrient deficiencies. In addition, perioperative anaemia has been related with increased postoperative morbidity and mortality and poorer quality of life aft...

  20. The Pharmacokinetics of the CYP3A Substrate Midazolam in Morbidly Obese Patients Before and One Year After Bariatric Surgery

    Brill, Margreke J.; van Rongen, Anne; van Dongen, Eric P.; van Ramshorst, Bert; Hazebroek, Eric J; Darwich, Adam S; Rostami-Hodjegan, Amin; Knibbe, Catherijne A.


    Purpose Bariatric surgery is nowadays commonly applied as treatment for morbid obesity (BMI > 40 kg/m2). As information about the effects of this procedure on a drug’s pharmacokinetics is limited, we aimed to evaluate the pharmacokinetics of CYP3A probe substrate midazolam after oral and intravenous administration in a cohort of morbidly obese patients that was studied before and 1 year post bariatric surgery. Methods Twenty morbidly obese patients (aged 26–58 years) undergoing bariatric surg...

    O'Kane, Mary; Parretti, Helen M; Hughes, Carly A; Sharma, Manisha; Woodcock, Sean; Puplampu, Tamara; Blakemore, Alexandra I; Clare, Kenneth; MacMillan, Iris; Joyce, Jacqueline; Sethi, Su; Barth, Julian H


    Bariatric surgery can facilitate weight loss and improvement in medical comorbidities. It has a profound impact on nutrition, and patients need access to follow-up and aftercare. NICE CG189 Obesity emphasized the importance of a minimum of 2 years follow-up in the bariatric surgical service and recommended that following discharge from the surgical service, there should be annual monitoring as part of a shared care model of chronic disease management. NHS England Obesity Clinical Reference Group commissioned a multi-professional subgroup, which included patient representatives, to develop bariatric surgery follow-up guidelines. Terms of reference and scope were agreed upon. The group members took responsibility for different sections of the guidelines depending on their areas of expertise and experience. The quality of the evidence was rated and strength graded. Four different shared care models were proposed, taking into account the variation in access to bariatric surgical services and specialist teams across the country. The common features include annual review, ability for a GP to refer back to specialist centre, submission of follow-up data to the national data base to NBSR. Clinical commissioning groups need to ensure that a shared care model is implemented as patient safety and long-term follow-up are important. PMID:27166136

  2. The bariatric patient: an overview of perioperative care.

    Fencl, Jennifer L; Walsh, Angela; Vocke, Dawn


    Obesity (ie, a body mass index of ≥30 kg/m(2)) is increasing in the United States. As a result, more overweight individuals are being surgically treated for weight loss, thus making it imperative for perioperative RNs to understand obesity's effects on patients' health, its contribution to significant comorbidities (eg, diabetes, cardiovascular disease, hypertension, sleep apnea, musculoskeletal issues, stroke), the perioperative care requirements (eg, specialized instruments and equipment, positioning and lifting aids), and unique needs of these patients (eg, diet, counseling). It is vital that the perioperative nurse accurately assesses the patient undergoing bariatric surgery to provide safe and appropriate nursing interventions during the perioperative continuum of care. PMID:26227516

  3. Minimally invasive surgical procedures for the treatment of lumbar disc herniation

    Raspe, Heiner


    as an intermediate therapeutical option between conservative and operative management of small lumbar disc herniations or protrusions causing sciatica. Two RCT comparing transforaminal endoscopic procedures with microdiscectomy in patients with sciatica and small non-sequestered disc herniations show comparable short and medium term overall success rates. Concerning speed of recovery and return to work a trend towards more favourable results for the endoscopic procedures is noted. It is doubtful though, whether these results from the eleven and five years old studies are still valid for the more advanced procedures used today. The only RCT comparing the results of automated percutaneous lumbar discectomy to those of microdiscectomy showed clearly superior results of microdiscectomy. Furthermore, success rates of automated percutaneous lumbar discectomy reported in the RCT (29% differ extremely from success rates reported in case series (between 56% and 92%. The literature search retrieves no controlled trials to assess efficacy and/or effectiveness of laser-discectomy, percutaneous manual discectomy or endoscopic procedures using a posterior approach in comparison to the standard procedures. Results from recent case series permit no assessment of efficacy, especially not in comparison to standard procedures. Due to highly selected patients, modi-fications of operative procedures, highly specialised surgical units and poorly standardised outcome assessment results of case series are highly variable, their generalisability is low. The results of the five economical analyses are, due to conceptual and methodological problems, of no value for decision-making in the context of the German health care system. Discussion: Aside from low methodological study quality three conceptual problems complicate the interpretation of results. 1. Continuous further development of technologies leads to a diversity of procedures in use which prohibits generalisation of study results

  4. The changing distribution of a major surgical procedure across hospitals: were supply shifts and disequilibrium important?

    Friedman, B; Elixhauser, A


    This paper describes and analyzes the changing distribution across hospitals in the U.S. of total hip replacement surgery (THR) for the period 1980-1987. THR is one of the most costly single procedures contributing to health care expenses. Also, the use of THR exhibits a particularly high degree of geographic variation. Recent research pointed to shifts in demand as one plausible economic explanation for increasing use of THR. This paper questions whether shifts in supply may have been large enough to explain changes in patient mix and the relationship of patient mix to the number of procedures performed at a particular hospital. In addition, the relationship between total use of THR and the local availability of orthopaedic surgeons as well as the average allowable Medicare fee for standardized physician services is analyzed. These relationships might yield evidence to support a scenario of induced demand beyond the optimum for patients' welfare, or evidence of supply increase within a disequilibrium scenario. This study, using data for all THR patients in a large sample of hospitals, tends to reject the formulation of a market with independent supply and demand shifts where the supply shifts were the dominant forces. Hospitals with a larger number of THRs performed did not see a higher percentage of older, sicker, and lower income patients. It was more likely that demand shifts generated increases in capacity for surgical services. Moreover, there was little evidence for a persistent disequilibrium and only weak evidence for inducement. Also, we found little evidence that hospitals responded to financial incentives inherent in the Medicare payment system after 1983 to select among THR candidates in favour of those with below average expected cost. We did observe increased concentration over time of THR procedures in facilities with high volume--suggesting plausible demand shifts towards hospitals with a priori quality and cost advantages or who obtained those

  5. News media reports of patient deaths following 'medical tourism' for cosmetic surgery and bariatric surgery.

    Turner, Leigh


    Contemporary scholarship examining clinical outcomes in medical travel for cosmetic surgery identifies cases in which patients traveled abroad for medical procedures and subsequently returned home with infections and other surgical complications. Though there are peer-reviewed articles identifying patient deaths in cases where patients traveled abroad for commercial kidney transplantation or stem cell injections, no scholarly publications document deaths of patients who traveled abroad for cosmetic surgery or bariatric surgery. Drawing upon news media reports extending from 1993 to 2011, this article identifies and describes twenty-six reported cases of deaths of individuals who traveled abroad for cosmetic surgery or bariatric surgery. Over half of the reported deaths occurred in two countries. Analysis of these news reports cannot be used to make causal claims about why the patients died. In addition, cases identified in news media accounts do not provide a basis for establishing the relative risk of traveling abroad for care instead of seeking elective cosmetic surgery at domestic health care facilities. Acknowledging these limitations, the case reports suggest the possibility that contemporary peer-reviewed scholarship is underreporting patient mortality in medical travel. The paper makes a strong case for promoting normative analyses and empirical studies of medical travel. In particular, the paper argues that empirically informed ethical analysis of 'medical tourism' will benefit from rigorous studies tracking global flows of medical travelers and the clinical outcomes they experience. The paper contains practical recommendations intended to promote debate concerning how to promote patient safety and quality of care in medical travel. PMID:22420449

  6. Defining the role of bariatric surgery in polycystic ovarian syndrome patients

    Shaveta M Malik


    Full Text Available Polycystic ovarian syndrome (PCOS is the most common endocrine disorder in women. To meet PCOS criteria, women must have a combination of hyperandrogenism, anovulation and ultrasound findings. Almost 10% of all reproductive age women worldwide show signs of PCOS. Although women often seek care for gynecological or body image concerns, many PCOS women are at risk for metabolic syndrome (MS. Many of the metabolic consequences are overlooked and undertreated by physicians because these patients tend to be young, reproductive age women. MS and obesity coexist commonly with PCOS. These young women are predisposed to glucose abnormalities and ultimately diabetes mellitus, dyslipidemia and eventually cardiovascular disease. Bariatric surgery can be an effective means of weight loss in PCOS women. Surgical techniques have become safer and less invasive over time and have been found to be effective in achieving significant weight loss. Surgical options have also increased, giving patients more choices. Bariatric surgery may prevent or reverse metabolic syndrome. Bariatric surgery may also have reproductive benefits in PCOS patients. Although bariatric surgery has historically been performed in older, reproductive aged women, it has recently gained favor in adolescents as well. This is of particular importance due to the prevalence of both PCOS and MS in adolescents. Treatment of PCOS and MS certainly requires a combination of medical therapy, psychological support and lifestyle modifications. These treatments are difficult and often frustrating for patients and physicians. Bariatric surgery can be effective in achieving significant weight loss, restoration of the hypothalamic pituitary axis, reduction of cardiovascular risk and even in improving pregnancy outcomes. Ultimately, bariatric surgery should be considered part of the treatment in PCOS women, especially in those with MS.

  7. Case of successful surgical treatment for atrial fibrillation using «Maze III» procedure: 18 years on

    Bockeria L. A.


    Full Text Available Atrial fibrillation is one of the most common types of heart rhythm disturbances in humans. «Maze III» procedure is considered to be the most radical methods of surgical treatment for atrial fibrillation. It is performed according to the «incision-suture» technique using median sternotomy and cardiopulmonary bypass. This procedure is less frequently used in clinical practice because of its technical complexity, but the evaluation of longterm results is necessary to answer the question of expediency for using the new methods of surgical treatment for atrial fibrillation which were developed in view of essential principles of classical surgery. The clinical case of successful surgical treatment for atrial fibrillation with 18-years of follow-up is presented in the article.

  8. Utilization of surgical procedures for pelvic organ prolapse: a population-based study in Olmsted County, Minnesota, 1965–2002

    Babalola, Ebenezer O.; Bharucha, Adil E; Melton, L. Joseph; Schleck, Cathy D.; Zinsmeister, Alan R.; Klingele, Christopher J.; Gebhart, John B.


    To describe trends in the utilization of surgical procedures for pelvic organ prolapse among women in Olmsted County, MN, we retrospectively identified all county residents undergoing pelvic organ prolapse repair from January 1, 1965 through December 31, 2002. From 1965 to 2002, 3,813 women had pelvic organ prolapse surgeries: 3,126 had hysterectomy combined with pelvic floor repair (PFR) procedures and 687 had PFR alone. The age-adjusted utilization of hysterectomy plus PFR and of PFR alone ...

  9. The prophylactic use of C1 inhibitor in hereditary angioedema patients undergoing invasive surgical procedures: a retrospective study

    Gavigan, Geneviève; Yang, William H; Santucci, Stephanie; Harrison, Rachel; Karsh, Jacob


    Background Hereditary Angioedema (HAE) is a rare autosomal dominant condition characterized by episodic angioedema, which may be triggered by invasive procedures and surgery. C1 inhibitor (C1 INH) was approved in the United States and Canada in 2009 and 2010, respectively, for the treatment of acute attacks. Most recently in April 2013, it was approved in Europe for short-term prophylaxis (STP), prior to medical, dental, or surgical procedures, to prevent HAE attacks in both children and adul...

  10. A New Surgical Procedure “Dumbbell-Form Resection” for Selected Hilar Cholangiocarcinomas With Severe Jaundice

    Wang, Shuguang; Tian, Feng; Zhao, Xin; Li, Dajiang; He, Yu; Li, Zhihua; Chen, Jian


    Abstract The aim of the study is to evaluate the therapeutic effect of a new surgical procedure, dumbbell-form resection (DFR), for hilar cholangiocarcinoma (HCCA) with severe jaundice. In DFR, liver segments I, IVb, and partial V above the right hepatic pedicle are resected. Hemihepatectomy is recognized as the preferred procedure; however, its application is limited in HCCAs with severe jaundice. Thirty-eight HCCA patients with severe jaundice receiving DFR and 70 receiving hemihepatectomy from January 2008 to January 2013 were included. Perioperative parameters, operation-related morbidity and mortality, and post-operative survival were analyzed. A total of 21.1% patients (8/38) in the DFR group received percutaneous transhepatic biliary drainage (PTBD), which was significantly <81.4% (57/70) in the hemihepatectomy group. The TBIL was higher in the DFR group at operation (243.7 vs 125.6 μmol/L, respectively). The remnant liver volume was significantly higher after DFR. The operation-related morbidity was significantly lower after DFR than after hemihepatectomy (26.3% vs 48.6%, respectively). None of the patients died during the perioperative period after DFR, whereas 3 died after hemihepatectomy. There was no difference in margin status, histological grade, lymph-node involvement, and distant metastasis between the 2 groups. The 1-, 3-, and 5-year survival rates after DFR (68.4%, 32.1%, and 21.4%, respectively) showed no significant difference with those after hemihepatectomy (62.7%, 34.6%, and 23.3%, respectively). Kaplan–Meier analysis indicated that overall survival and recurrence after DFR demonstrated no significant difference compared with hemihepatectomy. DFR appears to be feasible for selected HCCA patients with severe jaundice. However, its indications should be restricted. PMID:26765439

  11. Development of a mass spectrometry sampling probe for chemical analysis in surgical and endoscopic procedures.

    Chen, Chien-Hsun; Lin, Ziqing; Garimella, Sandilya; Zheng, Lingxing; Shi, Riyi; Cooks, R Graham; Ouyang, Zheng


    A sampling probe based on ambient desorption ionization was designed for in vivo chemical analysis by mass spectrometry in surgical and endoscopic procedures. Sampling ionization of analytes directly from tissue was achieved by sealing the sampling tip against the tissue surface without allowing leakage of the auxiliary gas used for desorption ionization. The desorbed charged species were transferred over a long distance (up to 4 m) through a flexible tube of internal diameter as small as 1/16 in. to the inlet of the mass spectrometer used for analysis. The conditions used for desorption electrospray ionization (DESI) were optimized to achieve biocompatibility for clinical applications while obtaining adequate efficiency for the analysis. This optimization involved the removal of high voltage and use of pure water as a spray solvent instead of the organic solvents or aqueous mixtures normally used. Improved sensitivity was achieved under these conditions by increasing the gas flow rate in the transfer tube. The destructive effect on tissue surfaces associated with typical desorption ionization was avoided by altering the local gas dynamics in the sample area without compromising the overall analysis efficiency.

  12. Remifentanil-based anesthesia versus a propofol technique for otologic surgical procedures.

    Jellish, W S; Leonetti, J P; Avramov, A; Fluder, E; Murdoch, J


    Otologic procedures require a still surgical field and are associated with a 50% incidence of emetic symptoms. Propofol reduces nausea and vomiting but not intraoperative movement. This study compares a remifentanil/propofol anesthetic to a propofol/fentanyl combination to determine which provides the best perioperative conditions for otologic microsurgery. Eighty healthy patients were randomly assigned to receive one of the anesthetic combinations. Demographic data, hemodynamic variables, movement, and bispectral index monitoring values in addition to anesthetic emergence, nausea, vomiting, pain, and other recovery variables were compared between groups with appropriate statistical methods. Both groups were similar. Times to eye opening (7.7 +/- 0.7 vs 12.4 +/- 1.2 minutes) and extubation (9.8 +/- 0.9 vs 12.4 +/- 1.0 minutes) were shorter with remifentanil. This group also had lower hemodynamic variables and movement (23% vs 65%) under anesthesia. Postoperative pain was mild in both groups, but remifentanil patients had more than the propofol group. All other postoperative parameters were similar. Remifentanil-based anesthesia produces better hemodynamic stability, less movement, and faster emergence after otologic surgery, with propofol's antiemetic effect, for the same cost. PMID:10652394

  13. Surgical Procedures of the Elbow: A Nationwide Cross-Sectional Observational Study in the United States

    Ahmet Kinaci


    Full Text Available Background:  Elbow surgery is shared by several subspecialties. We were curious about the most common elbow surgeries and their corresponding diagnoses in the United States.   Methods:  We used the National Hospital Discharge Survey (NHDS and the National Survey of Ambulatory Surgery (NSAS data gathered in 2006-databases that together provide an estimate of all inpatient and ambulatory surgical care in the US.  Results:  An estimated 150,000 elbow surgeries were performed in the US in 2006, 75% in an outpatient setting. The most frequent diagnosis treated operative was enthesopathy (e.g. lateral epicondylitis and it was treated with several different procedures. More than three quarters of all elbow surgeries treated enthesopathy, cubital tunnel syndrome, or fracture (radial head in particular. Arthroscopy and arthroplasty accounted for less than 10% of all elbow surgeries.  Conclusions:  Elbow surgery in the United States primarily addresses enthesopathies such as tennis elbow, cubital tunnel syndrome, and trauma. It is notable that some of the most common elbow surgeries (those that address enthesopathy and radial head fracture are some of the most variably utilized and debated.

  14. Psychological and health comorbidities before and after bariatric surgery: a longitudinal study

    Susana Sofia Pereira da Silva


    Full Text Available INTRODUCTION: Morbid obesity has multiple implications for psychological and physical health. Bariatric surgery has been selected as the treatment of choice for this chronic disease, despite the controversial impact of the surgery on psychosocial health. The objective of this study was to describe candidates for bariatric surgery and analyze changes in weight, psychopathology, personality, and health problems and complaints at 6- and 12- month follow-up assessments. METHODS: Thirty obese patients (20 women and 10 men with a mean age of 39.17±8.81 years were evaluated in different dimensions before surgery and 6 and 12 months after the procedure. RESULTS: Six and 12 months after bariatric surgery, patients reported significant weight loss and a significant reduction in the number of health problems and complaints. The rates of self-reported psychopathology were low before surgery, and there were no statistically significant changes over time. The conscientiousness, extraversion, and agreeableness dimensions increased, but neuroticism and openness remained unchanged. All changes had a medium effect size. CONCLUSIONS: Our results suggest that patients experience significant health improvements and some positive personality changes after bariatric surgery. Even though these findings underscore the role of bariatric surgery as a relevant treatment for morbid obesity, more in-depth longitudinal studies are needed to elucidate the evolution of patients after the procedure.

  15. A role for exercise after bariatric surgery?

    Coen, Paul M; Goodpaster, Bret H


    Obesity predisposes an individual to develop numerous comorbidities, including type 2 diabetes, and represents a major healthcare issue in many countries worldwide. Bariatric surgery can be an effective treatment option, resulting in profound weight loss and improvements in metabolic health; however, not all patients achieve similar weight loss or metabolic improvements. Exercise is an excellent way to improve health, with well-characterized physiological and psychological benefits. In the present paper we review the evidence to determine whether there may be a role for exercise as a complementary adjunct therapy to bariatric surgery. Objectively measured physical activity data indicate that most patients who undergo bariatric surgery do not exercise enough to reap the health benefits of exercise. While there is a dearth of data on the effects of exercise on weight loss and weight loss maintenance after surgery, evidence from studies of caloric restriction and exercise suggest that similar adjunctive benefits may be extended to patients who perform exercise after bariatric surgery. Recent evidence from exercise interventions after bariatric surgery suggests that exercise may provide further improvements in metabolic health compared with surgery-induced weight loss alone. Additional randomized controlled exercise trials are now needed as the next step to more clearly define the potential for exercise to provide additional health benefits after bariatric surgery. This valuable evidence will inform clinical practice regarding much-needed guidelines for exercise after bariatric surgery. PMID:26228356

  16. Fontan procedure: imaging of normal post-surgical anatomy and the spectrum of cardiac and extracardiac complications

    Univentricular congenital heart diseases include a range of entities that result in a functionally single ventricular chamber. Although the only curative therapy is cardiac transplantation, there are several palliative surgical techniques that prevent ventricular volume overload, diverting part or all the systemic venous circulation into the pulmonary arteries. The modern Fontan procedure, which consists of anastomosing both the superior (SVC) and inferior vena cava (IVC) to the right pulmonary artery (RPA), is nowadays the last step before transplantation. The importance of imaging in these entities lies not only in the understanding of the new circuit established after surgical correction, but also in the early detection of the wide spectrum of cardiac and extracardiac complications that can occur due to the new physiological condition. Due to the increased survival of these patients, long-term complications are becoming more common. The main cardiac complications are atrial enlargement, ventricular dysfunction, and stenosis or thrombosis of the conduit. Pulmonary artery stenosis, pulmonary arteriovenous fistulae (PAVF), systemic-pulmonary veno venous shunts (VVS), hepatic congestion, cardiac cirrhosis, and protein-losing enteropathy are potential extracardiac complications. - Highlights: • Fontan procedure is the main palliative surgical procedure for univentricular heart correction. • Fontan procedure entails the anastomosis of SVC and IVC to the RPA. • Complications are becoming more common due to the increased survival of patients with Fontan

  17. [Assessment of bariatric surgery results].

    Barros, Lívia Moreira; Frota, Natasha Marques; Moreira, Rosa Aparecida Nogueira; de Araújo, Thiago Moura; Caetano, Joselany Áfio


    The objective was to evaluate the results of bariatric surgery in patients in the late postoperative period using the Bariatric Analysis and Reporting Outcome System (BAROS). This cross-sectional study was conducted from November 2011 to June 2012 at a hospital in the state of Ceará, Brazil. Data were collected from 92 patients using the BAROS protocol, which analyzes weight loss, improved comorbidities, complications, reoperations and Quality of Life (QoL). Data were analysed using the chi-squared test, Fischer's exact test and the Mann-Whitney test. There was a reduction in the Body Mass Index (47.2±6.8 kg/m2 in the pre-operatory and 31.3±5.0 kg/m2 after surgery, p<0.001). The comorbidity with the highest resolution was arterial hypertension (p<0.001), and QV improved in 94.6% of patients. The main complications were hair loss, incisional hernia and cholelithiasis. The surgery provided satisfactory weight loss and improvements in the comorbidities associated to a better QL. Use of the BAROS protocol allows nurses to plan interventions and maintain the good results. PMID:26098798

  18. Bariatric surgery in type 1 diabetes mellitus: long-term experience in two cases

    Nuria Fuertes-Zamorano


    Full Text Available In patients with obesity and type 2 diabetes, recommendations for bariatric surgery are well established. However, no consensus exists regarding its role for the management of patients with type 1 diabetes and morbid obesity. We present the long-term follow-up of two women with type 1 diabetes, morbid obesity and associated comorbidities, who underwent malabsorptive bariatric surgery. More than four years after the procedure, both have a body mass index (BMI within the normal range and HbA1c levels below 7%. Also, they have been able to reduce their insulin requirements in more than 50%, their associated comorbidities have disappeared, and their overall quality of life has significantly improved. We compare our results with other recently published ones, emphasizing potential indications of bariatric surgery for patients with type 1 diabetes.

    Background: Understanding haemodynamic effects of muscle relaxants may help us in selection of most appropriate muscle relaxant in a given case after considering preoperative cardiac status, preoperative medications, anaesthetic drugs to be used, nature of surgery and desirable intraoperative hemodynamics. Hemodynamic effects of rocuronium are not as clear as vecuronium. Present study was conducted to compare haemodynamic parameters during general anaesthesia for elective surgical procedures ...

  1. Management of asymptomatic carotid stenosis in patients undergoing general and vascular surgical procedures

    Paciaroni, M; Caso, V; Acciarresi, M; Baumgartner, R.; Agnelli, G.


    Current available data do not seem to support the strategy for carotid endarterectomy prior to surgical intervention in patients with asymptomatic carotid stenosis. However, in patients with coronary artery disease, synchronous carotid endarterectomy and coronary artery bypass grafting should be considered where there is a proven surgical risk of 60% or bilateral carotid stenosis >75% on the same side as the most severe stenosis. Clarification of the optimal strategy requires an adequately po...

    Sorin Hostiuc


    Full Text Available Abstract Morbid obesity has become a very common problem worldwide, causing severe health-related consequences including cardiovascular or metabolic diseases, arthritis, sleep apnea, or an increased risk of cancer. Bariatric surgery was shown to be the only way to achieve sustainable weight loss and to decrease the frequency and severity of metabolic and cardiovascular comorbidities. The purpose of this article is to present a case of bariatric surgery complicated with lesion of the aorta with a lethal outcome.

  3. Kidney Stone Risk Following Modern Bariatric Surgery

    Gonzalez, Ricardo D.; Canales, Benjamin K.


    Over the past 10 years, a variety of reports have linked bariatric surgery to metabolic changes that alter kidney stone risk. Most of these studies were retrospective, lacked appropriate controls, or involved bariatric patients with a variety of inclusion criteria. Despite these limitations, recent clinical and experimental research has contributed to our understanding of the pathophysiology of stone disease in this high-risk population. This review summarizes the urinary chemistry profiles t...

  4. Pregnancy following bariatric requires special attention

    In the latest years the number of pregnant women having undergone bariatric surgery before pregnancy has increased rapidly. In pregnancy, they seem to have a reduced risk of obesity-related complications but an increased risk of mechanical complications causing small bowel obstruction and...... complications due to malabsorption. This article reviews the effect of bariatric surgery before pregnancy on obstetric and neonatal outcomes and provides, based on the limited available evidence, recommendations for the management of pregnancy in these women....

    Wharton, S; Serodio, K J; Kuk, J L; Sivapalan, N; Craik, A; Aarts, M-A


    The objective of the study was to assess the interest, views and patient-perceived barriers to bariatric surgery among surgery-eligible patients. Surveys were completed at a weight management clinic and local hospital in Ontario, Canada. Patients were ≥18 years of age with a body mass index (BMI) >40 kg m(-2) or BMI > 35 kg m(-2) with ≥1 comorbidity. The sample included 105 participants, 73.3% female, with a mean BMI of 46.6 ± 7.1 kg m(-2) . Only 33.3% of participants were interested in surgery; 50.5% of participants were not interested and 16.2% had mixed feelings. Participants identified risks (69.5%) and side effects (57.1%) as significant surgical barriers. Interested participants were more likely to perceive themselves as obese, were unhappy with their current weight loss method and were less likely to fear surgery (P effectiveness of bariatric surgery, the majority of qualified patients are not interested in surgery mainly due to the perceived risk of surgery in general and satisfaction with current non-surgical weight loss efforts. The self-perception of obesity, as opposed to medical comorbidities, may be a stronger driver of the decision to have bariatric surgery. It is unclear if patients are aware of the effectiveness of bariatric surgery to help improve comorbidities or if bariatric surgery is perceived as being more cosmetic in nature. PMID:26910303

    To evaluate the surgical outcomes following radical antegrade modular pancreatosplenectomy (RAMPS)for pancreatic cancer.METHODS:Twenty-four patients underwent RAMPS with curative intent between January 2005 and June 2009 at the National Cancer Center,South Korea.Clinicopathologic data,including age,sex,operative findings,pathologic results,adjuvant therapy,postoperative clinical course and follow-up data were retrospectively collected and analyzed for this study.RESULTS:Twenty-one patients (87.5%) underwent distal pancreatectomy and 3 patients (12.5%) underwent total pancreatectomy using RAMPS.Nine patients (37.5%) underwent combined vessel resection,including 8 superior mesenteric-portal vein resections and 1 celiac axis resection.Two patients (8.3%) underwent combined resection of other organs,including the colon,stomach or duodenum.Negative tangential margins were achieved in 22 patients (91.7%).The mean tumor diameter for all patients was 4.09 ± 2.15 cm.The 2 patients with positive margins had a mean diameter of 7.25 cm.The mean number of retrieved lymph nodes was 20.92 ± 11.24 and the node positivity rate was 70.8%.The median survival of the 24 patients was 18.23 ± 6.02 mo.Patients with negative margins had a median survival of 21.80 ± 5.30 mo and those with positive margins had a median survival of 6.47 mo (P =0.021).Nine patients (37.5%) had postoperative complications,but there were no postoperative mortalities.Pancreatic fistula occurred in 4 patients (16.7%):2 patients had a grade A fistula and 2 had a grade B fistula.On univariate analysis,histologic grade,positive tangential margin,pancreatic fistula and adjuvant therapy were significant prognostic factors for survival.CONCLUSION:RAMPS is a feasible procedure for achieving negative tangential margins in patients with carcinoma of the body and tail of the pancreas.

  7. Financial costs and patients’ perceptions of medical tourism in bariatric surgery

    Kim, David H.; Sheppard, Caroline E.; de Gara, Christopher J.; Karmali, Shahzeer; Birch, Daniel W.


    Summary Many Canadians pursue surgical treatment for severe obesity outside of their province or country — so-called “medical tourism.” We have managed many complications related to this evolving phenomenon. The costs associated with this care seem substantial but have not been previously quantified. We surveyed Alberta general surgeons and postoperative medical tourists to estimate costs of treating complications related to medical tourism in bariatric surgery and to understand patients’ motivations for pursuing medical tourism. Our analysis suggests more than $560 000 was spent treating 59 bariatric medical tourists by 25 surgeons between 2012 and 2013. Responses from medical tourists suggest that they believe their surgeries were successful despite some having postoperative complications and lacking support from medical or surgical teams. We believe that the financial cost of treating complications related to medical tourism in Alberta is substantial and impacts existing limited resources. PMID:26574702

  8. Resting State Brain Connectivity After Surgical and Behavioral Weight Loss

    Lepping, Rebecca J.; Bruce, Amanda S.; Francisco, Alex; Yeh, Hung-Wen; Martin, Laura E.; Powell, Joshua N.; Hancock, Laura; Patrician, Trisha M.; Breslin, Florence J.; Selim, Niazy; Donnelly, Joseph E.; Brooks, William M.; Savage, Cary R.; Simmons, W. Kyle; Bruce, Jared M.


    OBJECTIVE We previously reported changes in food-cue neural reactivity associated with behavioral and surgical weight loss interventions. Resting functional connectivity represents tonic neural activity that may contribute to weight loss success. Here we explore whether intervention type is associated with differences in functional connectivity after weight loss. METHODS Fifteen obese participants were recruited prior to adjustable gastric banding surgery. Thirteen demographically matched obese participants were selected from a separate behavioral diet intervention. Resting state fMRI was collected three months after surgery/behavioral intervention. ANOVA was used to examine post-weight loss differences between the two groups in connectivity to seed regions previously identified as showing differential cue-reactivity after weight loss. RESULTS Following weight loss, behavioral dieters exhibited increased connectivity between left precuneus/superior parietal lobule (SPL) and bilateral insula pre- to post-meal and bariatric patients exhibited decreased connectivity between these regions pre- to post-meal (pcorrected<.05). CONCLUSIONS Behavioral dieters showed increased connectivity pre- to post-meal between a region associated with processing of self-referent information (precuneus/SPL) and a region associated with interoception (insula) whereas bariatric patients showed decreased connectivity between these regions. This may reflect increased attention to hunger signals following surgical procedures, and increased attention to satiety signals following behavioral diet interventions. PMID:26053145

  9. Is mammary reconstruction with the anatomical Becker expander a simple procedure? Complications and hidden problems leading to secondary surgical procedures: a follow-up study.

    Farace, Francesco; Faenza, Mario; Bulla, Antonio; Rubino, Corrado; Campus, Gian Vittorio


    Debate over the role of Becker expander implants (BEIs) in breast reconstruction is still ongoing. There are no clear indications for BEI use. The main indications for BEI use are one-stage breast reconstruction procedure and congenital breast deformities correction, due to the postoperative ability to vary BEI volume. Recent studies showed that BEIs were removed 5 years after mammary reconstruction in 68% of operated patients. This entails a further surgical procedure. BEIs should not, therefore, be regarded as one-stage prostheses. We performed a case-series study of breast reconstructions with anatomically shaped Becker-35™ implants, in order to highlight complications and to flag unseen problems, which might entail a second surgical procedure. A total of 229 patients, reconstructed from 2005 to 2010, were enrolled in this study. Data relating to implant type, volume, mean operative time and complications were recorded. All the patients underwent the same surgical procedure. The minimum follow-up period was 18 months. During a 5-year follow-up, 99 patients required secondary surgery to correct their complications or sequelae; 46 of them underwent BEI removal within 2 years of implantation, 56 within 3 years, 65 within 4 years and 74 within 5 years. Our findings show that two different sorts of complications can arise with these devices, leading to premature implant removal, one common to any breast implant and one peculiar to BEIs. The Becker implant is a permanent expander. Surgeons must, therefore, be aware that, once positioned, the Becker expander cannot be adjusted at a later date, as in two-stage expander/prosthesis reconstructions for instance. Surgeons must have a clear understanding of possible BEI complications in order to be able to discuss these with their patients. Therefore, only surgeons experienced in breast reconstruction should use BEIs. PMID:23478009

    Shah, S.; Shah, V.; Ahmed, A.R; Blunt, D M


    Obesity is an increasingly prevalent and costly problem faced by the healthcare system. The role of bariatric surgery in managing obesity has also increased with evidence showing a reduction in long-term morbidity and mortality. There are unique challenges faced by the radiology department in providing an imaging service for this population of patients, from technical and staffing requirements through to the interpretation of challenging post-surgical images. We describe these challenges and ...

  11. [A new concept in surgery of the digestive tract: surgical procedure assisted by computer, from virtual reality to telemanipulation].

    Marescaux, J; Clément, J M; Vix, M; Russier, Y; Tassetti, V; Mutter, D; Cotin, S; Ayache, N


    Surgical simulation increasingly appears to be an essential aspect of tomorrow's surgery. The development of a hepatic surgery simulator is an advanced concept calling for a new writing system which will transform the medical world: virtual reality. Virtual reality extends the perception of our five senses by representing more than the real state of things by the means of computer sciences and robotics. It consists of three concepts: immersion, navigation and interaction. Three reasons have led us to develop this simulator: the first is to provide the surgeon with a comprehensive visualisation of the organ. The second reasons is to allow for planning and surgical simulation that could be compared with the detailed flight-plan for a commercial jet pilot. The third lies in the fact that virtual reality is an integrated part of the concept of computer assisted surgical procedure. The project consists of a sophisticated simulator which must include five requirements: a) visual fidelity, b) interactivity, c) physical properties, d) physiological properties, e) sensory input and output. In this report we describe how to obtain a realistic 3D model of the liver from bi-dimensional 2D medical images for anatomical and surgical training. The introduction of a tumor and the consequent planning and virtual resection is also described, as are force feedback and real-time interaction. PMID:9752550

    Full Text Available Context Obesity in the elderly is associated with exacerbation of functional decline (dependency, that occurs with aging, because of decreased muscle mass and strength, and increased joint dysfunction. Consequently, there is progressive loss of independence, autonomy, chronic pain and impaired quality of life. The weight loss can bring benefits in all these aspects, especially when accompanied by exercises. Elderly patients with morbid obesity may be submitted to surgical treatment, taking into account that the massive weight loss, eventually caused by bariatric surgery, may exacerbate the loss of muscle mass and nutritional complications that may bring harm to the overall health and quality of life of these patients. The functional assessment of elderly patients, candidates for bariatric surgery and the extent to which surgery can bring benefits to the patients, in the field of functionality, has still to be determined. Objective To describe profile functionality in obese elderly referred to a bariatric surgery program. Methods Patients with age ≥60 and BMI ≥35 underwent comprehensive geriatric assessment that evaluates co morbidities, medication use, ability to perform basic activities of daily living and instrumental activities of daily living, and the “Timedupandgo” test to evaluate mobility, whose cut-off point was ≤10 seconds. Statistical analysis was performed in order to see if there is a positive correlation of dependency with BMI and age (over or under 65 years. Results Forty subjects have completed evaluation. The mean age was 64.1 years (60-72 and 75% were women. They had an average weight of 121.1 kg (72.7-204 and a mean BMI of 47.2 kg/m2 (35.8-68.9. 16 patients (40% have shown dependency for activities of daily living, 19 (47,5% for instrumental activities of daily living and 20 patients (50% had a “Timedupandgo” test over 10 seconds.

  13. Obesity, bariatric surgery and nutritional implications - doi:10.5020/18061230.2007.p259

    Michele Novaes Ravelli


    Full Text Available Obesity is an important nutritional deviation that is exponentially increasing in Brazil and in the world, becoming a public health problem. The World Health Organization verified in 2005 that 1.6 billion people above 15 years old were overweight and 400 million were obese. Among children, 20 million were overweight. Amongst the different treatments for the obesity the bariatric surgery has been used very often nowadays, for being effective against weight excess and associated co-morbidities, both for the adult and youngster populations. The surgical techniques are divided in restrictive, disabsorptive and mixed procedures. Each technique promotes digestive and absorptive distinct alterations, needing, therefore, an exclusive multidisciplinary educational program, directed both to pre and postsurgery periods, emphasizing the habits of physical activity and the necessity to adhere to the restricted dietary recommendations. The surgeries promote a severe reduction in the consumption, which induces to the ingestion of diets that are hypocaloric and deficient in micronutrients, with consequent nutritional complications.

  18. Surgical Exposure

    Hendra Chandra


    Surgical exposure is a surgical method to expose mucous or bone which prevent delayed or unerupted permanent crown teeth, in order to provide normal eruption and to prevent malocclusion. Surgical exposure is usually carried out on maxillary caninces as they have higher incidence of delayed eruption. Nevertheless, this procedure can also be performed on other teeth. For patient management, this procedure need cooperation betweent oral surgeon and orthodontist.

  19. Comprehensive evaluation of occupational radiation exposure to intraoperative and perioperative personnel from 18F-FDG radioguided surgical procedures

    The purpose of the current study was to comprehensively evaluate occupational radiation exposure to all intraoperative and perioperative personnel involved in radioguided surgical procedures utilizing 18F-fluorodeoxyglucose (18F-FDG). Radiation exposure to surgeon, anesthetist, scrub technologist, circulating nurse, preoperative nurse, and postoperative nurse, using aluminum oxide dosimeters read by optically stimulated luminescence technology, was evaluated during ten actual radioguided surgical procedures involving administration of 18F-FDG. Mean patient dosage of 18F-FDG was 699 ± 181 MBq (range 451-984). Mean time from 18F-FDG injection to initial exposure of personnel to the patient was shortest for the preoperative nurse (75 ± 63 min, range 0-182) followed by the circulating nurse, anesthetist, scrub technologist, surgeon, and postoperative nurse. Mean total time of exposure of the personnel to the patient was longest for the anesthetist (250 ± 128 min, range 69-492) followed by the circulating nurse, scrub technologist, surgeon, postoperative nurse, and preoperative nurse. Largest deep dose equivalent per case was received by the surgeon (164 ± 135 μSv, range 10-580) followed by the anesthetist, scrub technologist, postoperative nurse, circulating nurse, and preoperative nurse. Largest deep dose equivalent per hour of exposure was received by the preoperative nurse (83 ± 134 μSv/h, range 0-400) followed by the surgeon, anesthetist, postoperative nurse, scrub technologist, and circulating nurse. On a per case basis, occupational radiation exposure to intraoperative and perioperative personnel involved in 18F-FDG radioguided surgical procedures is relatively small. Development of guidelines for monitoring occupational radiation exposure in 18F-FDG cases will provide reassurance and afford a safe work environment for such personnel. (orig.)

  20. Creation and Global Deployment of a Mobile, Application-Based Cognitive Simulator for Cardiac Surgical Procedures.

    Brewer, Zachary E; Ogden, William David; Fann, James I; Burdon, Thomas A; Sheikh, Ahmad Y


    Several modern learning frameworks (eg, cognitive apprenticeship, anchored instruction, and situated cognition) posit the utility of nontraditional methods for effective experiential learning. Thus, development of novel educational tools emphasizing the cognitive framework of operative sequences may be of benefit to surgical trainees. We propose the development and global deployment of an effective, mobile cognitive cardiac surgical simulator. In methods, 16 preclinical medical students were assessed. Overall, 4 separate surgical modules (sternotomy, cannulation, decannulation, and sternal closure) were created utilizing the Touch Surgery (London, UK) platform. Modules were made available to download free of charge for use on mobile devices. Usage data were collected over a 6-month period. Educational efficacy of the modules was evaluated by randomizing a cohort of medical students to either module usage or traditional, reading-based self-study, followed by a multiple-choice learning assessment tool. In results, downloads of the simulator achieved global penetrance, with highest usage in the USA, Brazil, Italy, UK, and India. Overall, 5368 unique users conducted a total of 1971 hours of simulation. Evaluation of the medical student cohort revealed significantly higher assessment scores in those randomized to module use versus traditional reading (75% ± 9% vs 61% ± 7%, respectively; P < 0.05). In conclusion, this study represents the first effort to create a mobile, interactive cognitive simulator for cardiac surgery. Simulators of this type may be effective for the training and assessment of surgical students. We investigated whether an interactive, mobile-computing-based cognitive task simulator for cardiac surgery could be developed, deployed, and validated. Our findings suggest that such simulators may be a useful learning tool. PMID:27568126

  3. Bariatric surgery and diabetes remission: Who would have thought it?

    Awadhesh Kumar Singh


    Full Text Available Type 2 diabetes mellitus (T2DM and obesity are increasingly common and major global health problems. The Edmonton obesity staging system clearly pointed towards increased mortality proportionate to the severity of obesity. Obesity itself triggers insulin resistance and thereby poses the risk of T2DM. Both obesity and T2DM have been associated with higher morbidity and mortality and this calls for institution of effective therapies to deal with the rising trend of complications arising out of this dual menace. Although lifestyle changes form the cornerstone of therapy for both the ailments, sustained results from this modalities is far from satisfactory. While Look AHEAD (action for HEAalth in diabetes study showed significant weight loss, reduction in glycated hemoglobin and higher remission rate of T2DM at 1 st year following intensive lifestyle measures; recurrence and relapse rate bounced back in half of subjects at 4 years, thereby indicating that weight loss and glycemic control is difficult to maintain in the long term with lifestyle interventions. Same recurrence phenomenon was also observed with pharmacotherapy with rimonabant, sibutramine and orlistat. Bariatric surgery has been seen to associate with substantial and sustained weight loss in morbidly obese patients. Interestingly, bariatric surgeries also induce higher rates of short and long-term diabetes remission. Although the exact mechanism behinds this diabetes remission are not well understood; improved insulin action, beta-cell function and complex interplay of hormones in the entero-insular axis appears to play a major role. This article reviews the effectiveness of bariatric procedures on remission or improvement in diabetes and put a perspective on its implicated mechanisms.

    Full Text Available Introducation: The long-term outcome and clinical results of gaparthroplasty used for the treatment of condylar ankylosis of the mandible in children with application of postoperative activator appliances and costochondral rib graft are evaluated and compared. The purpose of this study was to compare the effect of gap arthroplasty and costochondral graft methods on reankylosis, a mount of mouth opening and growth. Materials and Methods: A non-randomized, retrospective clinical study of l0 cases (5-12 years old of condylar ankylosis of the mandible, surgically treated during a 10 year period from 2002 to 2012 was performed. Four patients were treated by condylectomy and interpositional flap, whereas six were treated by condylectomy and immediate costachondral rib grafts. The first group underwent long-term postoperative therapy using removable activator appliances. Casts, radiographs, photographs, and computed tomography (CT were used post surgically to evaluate rib graft, condylar growth and function, occlusion, facial, and condylar symmetry. Data were analyzed by SPSS 16 statistical software using Mann-Whitney, Paired T-test and Chi-square tests. Results: Children with long-standing condylar ankylosis of the mandible treated by condylectomy and interpositional flap showed more favorably when activators were used post-surgically. Conclusions: Gaparthroplasty with functional activator post-operatively can be considering for TMJ ankylosis.

  5. Sarcina, a new threat in the bariatric era.

    Sopha, Sabrina C; Manejwala, Alif; Boutros, Cherif N


    First identified in humans by Goodsir in 1842, Sarcina were already known to cause fatal abomasal bloat in animals. Their pathogenicity in humans has only recently been characterized. Sarcina is not inherently pathogenic but, with a gastric ulcer and delayed gastric emptying, can result in perforation. We present a case report of a 32-year-old woman status post-gastric banding presenting with epigastric pain. Upper endoscopy revealed a gastric ulcer near the band. After deflation, upper gastrointestinal series showed passage of contrast and no perforation. Ulcer biopsy showed gastric contents composed of Sarcina. Proton pump inhibitors and antibiotics were administered. Follow-up endoscopy at an outside institution resulted in perforation. This case report supports a growing body of literature that Sarcina organisms contribute to ulcers and perforation. This is the first report of Sarcina in elective bariatric surgery patients, highlighting the high suspicion needed among pathologists evaluating ulcers in this unique surgical population.

  6. The Venetian blind technique: modification of the Pi procedure for the surgical correction of sagittal synostosis.

    Wexler, Andrew; Cahan, Leslie


    Numerous methods of surgical repair for scaphocephaly (sagittal synostosis) have been reported in the literature, from strip craniectomies to more complex methods of calvarial vault remodeling. While good cosmesis and restoration of a normal anteroposterior diameter may be obtained with these methods, a more rounded contour of the biparietal areas is often more difficult to achieve. We describe a modification of the Pi technique, described by Jane in 1976, that results in a more rounded contour of the biparietal areas. We report our experience on cranial vault remodeling for the correction of scaphocephaly in 51 patients from 1998 to 2011. PMID:23154346

  9. Update on dexmedetomidine: use in nonintubated patients requiring sedation for surgical procedures

    Mohanad Shukry


    Full Text Available Mohanad Shukry, Jeffrey A MillerUniversity of Oklahoma Health Sciences Center, Department of Anesthesiology, Children’s Hospital of Oklahoma, Oklahoma City, OK, USAAbstract: Dexmedetomidine was introduced two decades ago as a sedative and supplement to sedation in the intensive care unit for patients whose trachea was intubated. However, since that time dexmedetomidine has been commonly used as a sedative and hypnotic for patients undergoing procedures without the need for tracheal intubation. This review focuses on the application of dexmedetomidine as a sedative and/or total anesthetic in patients undergoing procedures without the need for tracheal intubation. Dexmedetomidine was used for sedation in monitored anesthesia care (MAC, airway procedures including fiberoptic bronchoscopy, dental procedures, ophthalmological procedures, head and neck procedures, neurosurgery, and vascular surgery. Additionally, dexmedetomidine was used for the sedation of pediatric patients undergoing different type of procedures such as cardiac catheterization and magnetic resonance imaging. Dexmedetomidine loading dose ranged from 0.5 to 5 μg kg-1, and infusion dose ranged from 0.2 to 10 μg kg-1 h-1. Dexmedetomidine was administered in conjunction with local anesthesia and/or other sedatives. Ketamine was administered with dexmedetomidine and opposed its bradycardiac effects. Dexmedetomidine may by useful in patients needing sedation without tracheal intubation. The literature suggests potential use of dexmedetomidine solely or as an adjunctive agent to other sedation agents. Dexmedetomidine was especially useful when spontaneous breathing was essential such as in procedures on the airway, or when sudden awakening from sedation was required such as for cooperative clinical examination during craniotomies.Keywords: dexmedetomidine, sedation, nonintubated patients

  10. Quantifying the Diversity and Similarity of Surgical Procedures Among Hospitals and Anesthesia Providers.

    Dexter, Franklin; Ledolter, Johannes; Hindman, Bradley J


    In this Statistical Grand Rounds, we review methods for the analysis of the diversity of procedures among hospitals, the activities among anesthesia providers, etc. We apply multiple methods and consider their relative reliability and usefulness for perioperative applications, including calculations of SEs. We also review methods for comparing the similarity of procedures among hospitals, activities among anesthesia providers, etc. We again apply multiple methods and consider their relative reliability and usefulness for perioperative applications. The applications include strategic analyses (e.g., hospital marketing) and human resource analytics (e.g., comparisons among providers). Measures of diversity of procedures and activities (e.g., Herfindahl and Gini-Simpson index) are used for quantification of each facility (hospital) or anesthesia provider, one at a time. Diversity can be thought of as a summary measure. Thus, if the diversity of procedures for 48 hospitals is studied, the diversity (and its SE) is being calculated for each hospital. Likewise, the effective numbers of common procedures at each hospital can be calculated (e.g., by using the exponential of the Shannon index). Measures of similarity are pairwise assessments. Thus, if quantifying the similarity of procedures among cases with a break or handoff versus cases without a break or handoff, a similarity index represents a correlation coefficient. There are several different measures of similarity, and we compare their features and applicability for perioperative data. We rely extensively on sensitivity analyses to interpret observed values of the similarity index. PMID:26678472

  11. Surgical management of oral submucous fibrosis in an edentulous patient: A procedural challenge

    Mahajan, Amit D.; Tatu, Rohit J.; Shenoy, Nithin A.; Sharma, Vaibhav S.


    Prosthetic rehabilitation of patients with oral submucous fibrosis (OSMF) offers a formidable challenge due to restricted mouth opening. Physiotherapy via interocclusal force application is the mainstay for surgical treatment. Herein, we report a case of a man with OSMF requiring construction of dentures. The main objective was to deliver intra-operative and post operative inter occlusal forces without fracturing the mandible and thus providing rehabilitation to the patient prosthetically. An edentulous male patient reported with grade IVA OSMF to our department to improve his mouth opening for denture construction. The patient was managed successfully using surgical sectioning of the fibrous bands. Inter occlusal force application for mouth opening during the operation and post operative physiotherapy were facilitated using custom-made occlusal splints. Satisfactory mouth opening was achieved, with good healing and no event of infection or fracture. Here, we propose an easy method to achieve adequate mouth opening in an edentulous patient of OSMF, with atrophic ridges; without the chances of fracture of either jaw. PMID:22442590

  12. Evaluation of propofol as a general anesthetic agent for minor oral surgical procedure.

    Jaggi, Nitin; Kalra, Amit; Baghla, Gunpreet Kaur; Medsinge, Sonali V; Purohit, Nikhil


    Nausea and vomiting following anesthesia is a distressing problem for the patient as it increases the recovery time, intensity of nursing care and delays discharge. The aim of randomized controlled single blind study is to evaluate the efficacy and safety of subhypnotic doses of propofol for the prevention of postoperative nausea and vomiting (PONV) in day care management of cases in oral and maxillofacial surgeries. Twenty-five patient of ASA-1 with age ranging from 12 to 40 years were scheduled for various maxillofacial surgical cases like fracture, cyst enucleation, surgical removal of 3rd molar, etc. were given propofol at the dose of 2 to 2.5 mg/kg as induction dose and sedation was maintained with the dose 5 to 10 mg/min. There was no significant effect on heart rate, systolic and diastolic blood pressure, respiratory rate and oxygen saturation intraoperatively. In conclusion, a subhypnotic dose of propofol is fast acting, safe and easily controllable, short acting general anesthetic agent with rapid recovery. The study found that the PONV was significantly reduced in the patient with propofol, no hemodynamic derangements were noted in the postoperative period. PMID:24309336

  13. Anaplastic carcinoma of the pancreas: Is there a role for palliative surgical procedure?

    Rajan Vaithianathan


    Full Text Available Anaplastic carcinoma (AC or undifferentiated carcinoma of the pancreas is a rare variant among the malignant pancreatic neoplasms. These tumors have a poor prognosis with survival measured in months. The role of surgical palliation to improve the quality of life is not well defined in these patients. We report a case of AC of pancreas in a 65-year-old male patient. Patient had upper abdominal pain with frequent bilious vomiting. Computed tomography scan of the abdomen showed a mass in the body of pancreas with possible infiltration of duodenojejunal flexure (DJF. Laparotomy revealed an inoperable mass with posterior fixity and involvement of the DJF. Patient underwent a palliative duodenojejunostomy. Tissue biopsy from the tumor showed pleomorphic type AC with giant cells. Patient had good symptomatic relief from profuse vomiting and progressed well at follow up. AC of pancreas is a rare and aggressive malignancy with dismal outlook. If obstructive symptoms are present due to duodenal involvement, a palliative bypass may be a worthwhile surgical option in selected cases.

  14. Post-bariatric abdominoplasty resulting in wound infection and dehiscence—Conservative treatment with medical grade honey: A case report and review of literature

    Dina Jarjis, Reem; Thomas Crewe, Bjørn; Henrik Matzen, Steen


    Introduction Wound complications in post-bariatric patients undergoing body-contouring surgery after massive weight loss are not uncommon and often, surgical debridement or conservative management is necessary. Honey is one of the most ancient remedies for wound care and it is also considered to possess debriding effects. Current research has demonstrated promising results showing that honey can improve wound granulation and epithelialization, reduce exudate and shorten healing times. Methods This case report has been reported in line with the CARE criteria. Presentation of case A 40 year-old female suffered wound infection and dehiscence after undergoing post-bariatric abdominoplasty. The patient was not interested in surgical revision and split skin grafting. Therefore, conservative wound treatment with topical Manuka honey was instituted resulting in significant clinical improvement and effective healing concurrently with good patient satisfaction. Discussion Surgical wound complications in post-bariatric patients undergoing abdominoplasty are common and often require surgical revision or conservative wound treatment. No previous publication has addressed outpatient treatment of post-bariatric abdominoplasty wound complications with medical grade honey. Conclusion Although more research is needed for definitive conclusions of honey’s efficacy, it is safe and as presented in our case, it may under certain circumstances reduce the need of surgical wound debridement and serve as a remedy for conservative treatment.

  15. Bariatric support line: a prospective study of support line activity.

    McDougall, Kirsten; Segaran, Ella; Sufi, Pratik; Heath, Dugal I


    In this prospective study, we examine the workload of the North London Obesity Surgery Service Bariatric telephone support line (BTSL) and its effects on service provision. Over a 3-month period (June to August 2008), a prospective record was kept of all calls, who they were from, whether the patient was presurgery or postsurgery, the type of procedure planned or undertaken, the nature of the enquiry, and the time taken to answer the query. Seventy-five (72%) calls were related to patients who were postsurgery and 29 (28%) presurgery. Patients scheduled for or having undergone Roux-en-Y gastric bypass accounted for 46 (44%) calls; 24 (23%) were preprocedure and 22 (21%) postprocedure. Patients scheduled for or having undergone gastric banding accounted for 56 (54%) calls; five (0.5%) were preprocedure and 51 (49%) postprocedure. Patients undergoing sleeve gastrectomy accounted for two (<1%) calls. Both calls were postprocedure. The reason for the support line enquiry was psychological support in 15 (14%) patients, questions postsurgery in 26 (25%), general enquiries in 27 (26%), and clinical enquiries in 36 (36%). This study of the BTSL has allowed us to identify areas of need within our bariatric population and improve the service we deliver. The changes we have made should lead to a better use of the team's time, greater patient compliance, and satisfaction as well as reduced complaints and litigation. PMID:19711140

  16. Surgical treatment of pathological obesity

    The obesity is the chronic non-communicable disease with a higher rate of growth in past 20 years. It is a risk factor for type 2 diabetes mellitus, high blood pressure, cardiovascular and respiratory affections, infertility, sexual and functional impotence, metabolic syndrome, load joint disorders and some types of cancer (breast, colon, prostate). The metabolic bariatric surgery is the surgical treatment more effective for the morbid obesity at long -and medium- term and not the pharmacologic treatment and the isolated diets. The aim of present historical review of the international literature on the evolution of surgical techniques of the bariatric surgery (malabsorption techniques, gastric restrictive techniques and mixed techniques), is to make available to those interested in this subject, a valuable therapeutic tool to be rationally used.

  17. Surgical Procedures for External Auditory Canal Carcinoma and the Preservation of Postoperative Hearing

    Hiroshi Hoshikawa


    Full Text Available Carcinoma of the external auditory canal (EAC is an unusual head and neck malignancy. The pathophysiology of these tumors is different from other skin lesions because of their anatomical and functional characteristics. Early-stage carcinoma of the EAC can be generally cured by surgical treatment, and reconstruction of the EAC with a tympanoplasty can help to retain hearing, thus improving the patients’ quality of life. In this study, we present two cases of early-stage carcinoma of the EAC treated by canal reconstruction using skin grafts after lateral temporal bone resection. A rolled-up skin graft with a temporal muscle flap was useful for keeping the form and maintaining the postoperative hearing. An adequate size of the skin graft and blood supply to the graft bed are important for achieving a successful operation.

    Full Text Available BACKGROUND:Liposuction is one of the most common elective surgical procedures in the U.S. and is supposed to be on the increase. AIM: The present study analyzes the effects of the surgical removal of subcutaneous adipose tissue by ultrasound-assisted megalipoplasty (UAM on BMI (body mass index, weight variation and anthropometric measurements in obese people. METHODS: Thirty premenopausal obese women underwent UAM, superwet technique. The mean aspirate volume was 17.5 L (range 9.2-26.3l. BMI, weight and anthropometric measurements were determined before and 1 day, 3 days, 6 months and 1year after the procedure. RESULTS: UAM reduced all parameters in the first six months after surgery, without further important changes in thefollowing six months. No major complications were noted in our study. Minor complications were present in 13 patients: seroma (10 patients, skin necrosis (2 patients, burns (1patient whichwere solved favorably. CONCLUSIONS: Our study demonstrates that UAM is safe andrepresents a reliable alternative to bariatric surgery, universally accepted in the treatment of obesity. It should be considered only if a dedicated team for the treatment of obesity exists (nutritionist, plastic surgeon, general surgeon, anesthesiologist and psychologist. UAM, by aesthetic benefits to patients (removing a large amount of fat with minimal blood loss, restored all patients satisfaction and esteem.

  20. Ménage-à-trois of bariatric surgery, bile acids and the gutmicrobiome

    Rajendra Raghow


    Bariatric surgeries have emerged as highly effectivetreatments for obesity associated type-2 diabetesmellitus. Evidently, the desired therapeutic endpointssuch as rates of weight loss, lower levels of glycatedhemoglobin and remission of diabetes are achievedmore rapidly and last longer following bariatric surgery,as opposed to drug therapies alone. In light of thesefindings, it has been suspected that in addition tocausing weight loss dependent glucose intolerance,bariatric surgery induces other physiological changesthat contribute to the alleviation of diabetes. However,the putative post-surgical neuro-hormonal pathwaysthat underpin the therapeutic benefits of bariatricsurgery remain undefined. In a recent report, Ryan andcolleagues shed new light on the potential mechanismsthat determine the salutary effects of bariatric surgeryin mice. The authors demonstrated that the improvedglucose tolerance and weight loss in mice after verticalsleeve gastrectomy (VSG) surgery were likely to becaused by post-surgical changes in circulating bileacids and farnesoid-X receptor (FXR) signaling, both ofwhich were also mechanistically linked to changes inthe microbial ecology of the gut. The authors arrivedat this conclusion from a comparison of genome-wide,metabolic consequences of VSG surgery in obese wildtype (WT) and FXR knockout mice. Gene expressionin the distal small intestines of WT and FXR knockoutmice revealed that the pathways regulating bile acidcomposition, nutrient metabolism and anti-oxidantdefense were differentially altered by VSG surgeryin WT and FXR-/- mice. Based on these data Ryanet al , hypothesized that bile acid homeostasis andFXR signaling were mechanistically linked to the gutmicrobiota that played a role in modulating post-surgicalchanges in total body mass and glucose tolerance.The authors' data provide a plausible explanation forputative weight loss-independent benefits of bariatricsurgery and its relationship with metabolism of bileacids.

  1. Surgical aspects of therapeutic concepts and diagnostic procedures in hepato-biliary and pancreatic tumours

    The aim of modern diagnostic procedures in hepato-biliary and pancreatic tumours is the characterization of origin, type and resectability of a lesion and the staging of the tumour. Furthermore, preoperative diagnostic methods should reduce the operative risk by demonstration of anatomical variations i.e. hepatic blood supply. In addition alternative therapeutic concepts like chemoembolization should be kept in mind. (orig./MG)

  2. Residual and Recurrent Acoustic Neuroma in Hearing Preservation Procedures: Neuroradiologic and Surgical Findings

    Mazzoni, Antonio; Calabrese, Vincenzo; Moschini, Luca


    Magnetic resonance imaging with gadolinium DTPA is currently the most accurate method for detecting small intracanalicular yestibular schwannomas. This imaging modality is not nearly as clear in diagnosis of a small residual or recurrent neuroma after a hearing preservation procedure. This study looked for gadolinium-enhanced MRI images mimicking recurrent lesions in 104 consecutive cases of unilateral acoustic neuroma removed with a hearing preservation technique by the retrosigmoid transmea...

  3. Short-term survival and effects of transmitter implantation into western grebes using a modified surgical procedure

    Gaydos, Joseph K.; Massey, J. Gregory; Mulcahy, Daniel M.; Gaskins, Lori A.; Nysewander, David; Evenson, Joseph; Siegel, Paul B.; Ziccardi, Michael H.


    Two pilot trials and one study in a closely related grebe species suggest that Western grebes (Aechmophorus occidentalis) will not tolerate intracoelomic transmitter implantation with percutaneous antennae and often die within days of surgery. Wild Western grebes (n = 21) were captured to evaluate a modified surgical technique. Seven birds were surgically implanted with intracoelomic transmitters with percutaneous antennae by using the modified technique (transmitter group), 7 received the same surgery without transmitter implantation (celiotomy group), and 7 served as controls (only undergoing anesthesia). Modifications included laterally offsetting the body wall incision from the skin incision, application of absorbable cyanoacrylate tissue glue to the subcutaneous space between the body wall and skin incisions, application of a waterproof sealant to the skin incision after suture closure, and application of a piece of porcine small intestine submucosa to the antenna egress. Survival did not differ among the 3 groups with 7 of 7 control, 6 of 7 celiotomy, and 6 of 7 transmitter birds surviving the 9-day study. Experimental birds were euthanized at the end of the study, and postmortem findings indicated normal healing. Significant differences in plasma chemistry or immune function were not detected among the 3 groups, and only minor differences were detected in red blood cell indices and plasma proteins. After surgery, the birds in the transmitter group spent more time preening tail feathers than those in the control and celiotomy groups. These results demonstrate that, in a captive situation, celiotomy and intracoelomic transmitter implantation caused minimal detectable homeostatic disturbance in this species and that Western grebes can survive implantation of intracoelomic transmitters with percutaneous antennae. It remains to be determined what potential this modified surgical procedure has to improve postoperative survival of Western grebes that are

  4. Clinical evaluation of the biological width following surgical crown-lengthening procedure: A prospective study

    Shobha K


    Full Text Available Background and Objectives: The purpose of this study was to evaluate the positional changes of the periodontal tissues, particularly the biological width, following surgical crown-lengthening in human subjects. Materials and Methods: A clinical trial study involving 15 patients was carried out for a period of 6 months. Sites were divided into 3 groups: treated (TT sites, adjacent (AD sites and nonadjacent (NAD sites. Free gingival margin [FGM], attachment level, pocket depth, bone level, biological width [BW] were recorded at baseline, 1, 3 and 6 months. Direct bone level after flap reflection was recorded before and after osseous resection at baseline only. Level of osseous crest was lowered based on BW, and supracrestal tooth structure needed using a combination of rotary and hand instruments. Statistical Analysis: Student t test and ANOVA were used. Results: Overall, apical displacement of FGM at TT, AD and NAD sites was statistically significant compared to baseline. The apical displacement of FGM at TT site was more when compared to that at AD and NAD sites at 3 and 6 months. The BW at the TT site was smaller at 1, 3 and 6 months compared to that at baseline. However, at all sites, BW was reestablished to the baseline value at the end of 6 months. Interpretation and Conclusion: The BW at TT sites was reestablished to its original vertical dimension by 6 months. In addition, a consistent 2-mm gain of coronal tooth structure was observed at the 1, 3 and 6-month examinations.

  5. [Middle ear cholesteatoma in children. Criteria for surgical procedure in 57 cases].

    Lerosey, Y; Andrieu-Guitrancourt, J; Marie, J P; Dehesdin, D


    Fifty five children with 57 cholesteatomas (2 bilateral cholesteatomas) were operated on by the same surgeon. The median period of follow-up was 87 months. Fifteen cases were lost to follow-up (26%). An ossicular erosion was present in 76% of cases. In the first stage, an "intact canal wall technique" (ICWT) was carried out in 44% and a "canal wall down technique" (CWDT) in 56%. A planned second stage was carried out in 76% of ICWT and 56% of CWDT. The incidence of residual cholesteatoma was 29% and the incidence of recurrent cholesteatoma was 11%. A third stage was carried out in 6 cases (11%) without residual or recurrent cholesteatoma. Finally a CWDT was performed in 65% and a ICWT in 35%. The hearing results were significantly better with ICWT but this was due to a better preoperative hearing level. Whatever the surgical technique, the hearing results were better in the presence of an intact stapes. The surgery was individualized. Although ICWT is our priority technique, it was feasible, in our experience, only in a minority of cases because of difficult ablation, insufficient eustachian tube function and very advanced sigmoid sinus or very low lying tegmen plate. Minimal postoperative cavity problems were encountered, even in children where in our experience the mastoidal pneumatisation is limited. PMID:9827188

  6. Patient-Specific Surgical Planning, Where Do We Stand? The Example of the Fontan Procedure.

    de Zélicourt, Diane A; Kurtcuoglu, Vartan


    The Fontan surgery for single ventricle heart defects is a typical example of a clinical intervention in which patient-specific computational modeling can improve patient outcome: with the functional heterogeneity of the presenting patients, which precludes generic solutions, and the clear influence of the surgically-created Fontan connection on hemodynamics, it is acknowledged that individualized computational optimization of the post-operative hemodynamics can be of clinical value. A large body of literature has thus emerged seeking to provide clinically relevant answers and innovative solutions, with an increasing emphasis on patient-specific approaches. In this review we discuss the benefits and challenges of patient-specific simulations for the Fontan surgery, reviewing state of the art solutions and avenues for future development. We first discuss the clinical impact of patient-specific simulations, notably how they have contributed to our understanding of the link between Fontan hemodynamics and patient outcome. This is followed by a survey of methodologies for capturing patient-specific hemodynamics, with an emphasis on the challenges of defining patient-specific boundary conditions and their extension for prediction of post-operative outcome. We conclude with insights into potential future directions, noting that one of the most pressing issues might be the validation of the predictive capabilities of the developed framework.

  7. Use of high-magnification loupes or surgical operating microscope when performing prophylaxes, scaling or root planing procedures.

    Mamoun, John


    The use of high-level magnification (6-8x loupes magnification, or higher degrees of magnification provided by the surgical operating microscope), combined with head-mounted, coaxial lighting, may improve the ability of a dentist or dental hygienist to perform prophylaxis or scaling and root planing procedures, compared to the performance of these tasks using unaided vision or entry-level (2.5x) magnification, combined with overhead operatory lighting. A magnified view of the supragingival contours of a tooth surface facilitates visualizing the dimensions and curvature of the unseen sub-gingival tooth surfaces, which facilitates detection and removal of calculus that is located on these subgingival surfaces. Improved calculus removal ability may lead to better periodontal disease outcomes. PMID:24245463

  8. A Gut Feeling to Cure Diabetes: Potential Mechanisms of Diabetes Remission after Bariatric Surgery

    Young Min Cho


    Full Text Available A cure for type 2 diabetes was once a mere dream but has now become a tangible and achievable goal with the unforeseen success of bariatric surgery in the treatment of both obesity and type 2 diabetes. Popular bariatric procedures such as Roux-en-Y gastric bypass and sleeve gastrectomy exhibit high rates of diabetes remission or marked improvement in glycemic control. However, the mechanism of diabetes remission following these procedures is still elusive and appears to be very complex and encompasses multiple anatomical and physiological changes. In this article, calorie restriction, improved β-cell function, improved insulin sensitivity, and alterations in gut physiology, bile acid metabolism, and gut microbiota are reviewed as potential mechanisms of diabetes remission after Roux-en-Y gastric bypass and sleeve gastrectomy.

  9. Surgical Efficiencies and Quality in the Performance of Voluntary Medical Male Circumcision (VMMC) Procedures in Kenya, South Africa, Tanzania, and Zimbabwe

    INTRODUCTION: This analysis explores the association between elements of surgical efficiency in voluntary medical male circumcision (VMMC), quality of surgical technique, and the amount of time required to conduct VMMC procedures in actual field settings. Efficiency outcomes are defined in terms of the primary provider's time with the client (PPTC) and total elapsed operating time (TEOT). METHODS: Two serial cross-sectional surveys of VMMC sites were conducted in Kenya, Republic of South Afri...

  10. Less Invasive Surgical Procedures Using Narrow-Diameter Implants: A Prospective Study in 20 Consecutive Patients.

    Lambert, France Emmanuelle; Lecloux, Geoffrey; Grenade, Charlotte; Bouhy, Alice; Lamy, Marc; Rompen, Eric Henri


    Narrow-diameter implants (NDIs) are increasingly produced and used in implant dentistry, especially since the introduction of new, more resistant materials. The objective of the present study was to evaluate the clinical performance of NDIs (3.3 mm) placed in thin alveolar crests. Twenty consecutive patients needing implant-supported fixed partial dentures and presenting an alveolar thickness ≤6 mm were treated with 1 or several NDIs. The surgical protocol was chosen according to the clinical situation: (1) flapless, (2) mini-cervical flap, (3) wide flap, (4) wide flap + guided bone regeneration (GBR). Implants were immediately loaded if the primary stability was higher than 20 Ncm. Implant survival and success, prosthodontic success rates, and patient-centered outcomes were evaluated after a follow-up period of 1 year. A total of 39 implants were placed in 20 patients, 12 and 27 implants in the anterior regions and in the posterior mandible, respectively. All but 1 implant reached an insertion torque higher than 20 Ncm and were loaded within 48 hours. The implant survival and success rates both reached 94.7%. The need for GBR was avoided in 60% of the implant sites. The mean peri-implant bone remodeling after a follow-up period of 1 year was -0.35 mm at the implant level. Peri-implant bone remodeling was higher in the posterior region, when the alveolar crest was thinner than 4 mm and GBR was required in addition. In conclusion, use of NDIs to restore partial edentation in sites with limited horizontal thickness seems to be an effective treatment option that prevented GBR in the majority of the present cases. Immediate provisionalization of NDIs does not seem to impair the results. PMID:24766161

  11. ProSeal laryngeal mask airway: An alternative to endotracheal intubation in paediatric patients for short duration surgical procedures

    Jaya Lalwani


    Full Text Available The laryngeal mask airway (LMA is a supraglottic airway management device. The LMA is preferred for airway management in paediatric patients for short duration surgical procedures. The recently introduced ProSeal (PLMA, a modification of Classic LMA, has a gastric drainage tube placed lateral to main airway tube which allows the regurgitated gastric contents to bypass the glottis and prevents the pulmonary aspiration. This study was done to compare the efficacy of ProSeal LMA with an endotracheal tube in paediatric patients with respect to number of attempts for placement of devices, haemodynamic responses and perioperative respiratory complications. Sixty children, ASA I and II, weighing 10-20 kg between 2 and 8 years of age group of either sex undergoing elective ophthalmological and lower abdominal surgeries of 30-60 min duration, randomly divided into two groups of 30 patients each were studied. The number of attempts for endotracheal intubation was less than the placement of PLMA. Haemodynamic responses were significantly higher (P<0.05 after endotracheal intubation as compared to the placement of PLMA. There were no significant differences in mean SpO 2 (% and EtCO 2 levels recorded at different time intervals between the two groups. The incidence of post-operative respiratory complications cough and bronchospasm was higher after extubation than after removal of PLMA. The incidence of soft tissue trauma was noted to be higher for PLMA after its removal. There were no incidences of aspiration and hoarseness/sore throat in either group. It is concluded that ProSeal LMA can be safely considered as a suitable and effective alternative to endotracheal intubation in paediatric patients for short duration surgical procedures.

  12. Surgical solutions to the problem of massive weight loss

    Jason A Spector; Steven M Levine; Nolan S Karp


    In response to the global rise in obesity, bariatric surgery has become increasingly more popular and successful.As a result, the demand for body contouring following massive weight loss is rapidly growing. Although bariatric procedures may produce impressive weight loss, people who achieve massive weight loss are often unhappy with the hanging folds of skin and subcutaneous tissue that remain. This review examines the nature of the post-bariatric deformity in each body region and briefly reviews common approaches to their treatment.

  13. A Fluidic Cell Embedded Electromagnetic Wave Sensor for Online Indication of Neurological Impairment during Surgical Procedures

    Lactate is known to be an indicator of neurological impairment during aortic aneurysm surgery. It is suggested that cerebrospinal fluid removed during such surgery could provide useful information in this regard. Medical professionals find the prospect of online detection of such analytes exciting, as current practice is time consuming and leads to multiple invasive procedures. Advancing from the current laboratory based analysis techniques to online methods could provide the basis for improved treatment regimes, better quality of care, and enhanced resource efficiency within hospitals. Accordingly, this article considers the use of a low power fluidic system with embedded electromagnetic wave sensor to detect varying lactate concentrations. Results are promising over the physiological range of 0 − 20 mmol/L with a calibration curve demonstrating an R2 value > 0.98.

    Introduction. Moderate obesity (BMI 30–35 kg/m2) affects 25% of the western population. The role of bariatric surgery in this context is currently debated, reserved for patients with comorbidity, as an alternative to conservative medical treatment. We describe our experience in moderately obese patients treated with bariatric surgery. Materials and Methods. Between September 2011 and September 2012, 25 patients with grade I obesity and comorbidities underwent bariatric surgery: preoperative m...

  15. Nutritional Optic Neuropathy Caused by Copper Deficiency After Bariatric Surgery.

    Rapoport, Yuna; Lavin, Patrick J M


    A 47-year-old woman developed severe bilateral visual loss 4 years after a Roux-en-Y gastric bypass and 24 years after vertical banded gastroplasty. Her serum copper level was 35 μg/dL (normal, 80-155 μg/dL). She was prescribed elemental copper tablets. Because her methylmalonic acid was slightly elevated, she received vitamin B12 injections as well. Five weeks later, she reported that her vision had improved and, at 10 months, her vision had recovered from 20/400 bilaterally to 20/25 in each eye. This case highlights the importance of checking copper levels in addition to the "more routine" vitamin levels, such as B1, B6, B12, E, and serum folate in patients with suspected nutritional optic neuropathy after bariatric surgery, particularly if it involved a bypass procedure. PMID:26828841

  16. Experimental Bariatric Surgery in Rats Generates a Cytotoxic Chemical Environment in the Gut Contents.

    Jia eLi


    Full Text Available Bariatric surgery, also known as metabolic surgery, is an effective treatment for morbid obesity which also offers pronounced metabolic effects including the resolution of type 2 diabetes and a decrease in cardiovascular disease and long-term cancer risk. However, the mechanisms of surgical weight loss and the long term consequences of bariatric surgery remain unclear. Bariatric surgery has been demonstrated to alter the composition of both the microbiome and the metabolic phenotype. We observed a marked shift towards Gammaproteobacteria, particularly Enterobacter hormaechei, following Roux-en-Y gastric bypass (RYGB surgery in a rat model compared with sham operated controls. Fecal water from RYGB surgery rats was highly cytotoxic to rodent cells (mouse lymphoma cell line, although In contrast, fecal water from sham operated animals showed no/very low cytotoxicity. This shift in the gross structure of the microbiome correlated with greatly increased cytotoxicity in a regulatory acceptable mouse lymphoma assay. Urinary phenylacetylglycine and indoxyl sulfate and fecal GABA, putrescine, tyramine and uracil were found to be inversely correlated with cell survival rate. This profound co-dependent response of mammalian and microbial metabolism to RYGB surgery and the impact on the cytotoxicity of the gut luminal environment suggests that RYGB exerts local and global metabolic effects which may have an influence on long term cancer risk and cytotoxic load.

  17. Bariatric Surgery in University Clinic Center Tuzla - Results After 30 Operations

    Ahmetasevic, Emir; Pasic, Fuad; Beslin, Miroslav Bekavac; Ilic, Miroslav; Ahmetasevic, Dzenita; Mesic, Mirza


    Introduction: Project of Bariatric surgery in University clinic center (UCC) Tuzla has been initiated in 2009 as an idea of professor Dešo Mešić and soon after that Bariatric surgical team led by doctor Fuad Pasic has been created. Material and methods: Practical team education was realized in Croatia in hospital „Sisters of Mercy” under supervision of professor Miroslav-Bekavac Beslin. First bariatric operations in UCC Tuzla has been done in 2011 and it was biliopancreatic diversion (BPD) Scopinaro. Results and discussion: So far there has been done 30 operations and among them there have been used almost all operative modalities - restrictive, malabsorptive and combined (laparoscopic gastric banding-LAPGB, Roux-y mini gastric bypass, open and laparoscopic gastric sleeve resection, and over mentioned Scopinaro’s BPD). Beginning results are very promising according to the fact that almost all operated patients after one year stopped using antihypertensive, antidiabetic and antidepressant therapy, that average year’s weight loss is 35-100 kilograms and total satisfactions of patients after surgeries is obvious.

  18. A Novel Surgical Procedure for Er:YAG Laser-Assisted Periodontal Regenerative Therapy: Case Series.

    Taniguchi, Yoichi; Aoki, Akira; Sakai, Kazuto; Mizutani, Koji; Meinzer, Walter; Izumi, Yuichi


    The objective of this study was to evaluate an Er:YAG laser (ErL) application for periodontal regenerative surgery in angular bone defects at nine sites in six patients. Debridement was thoroughly performed using a combination of curettage with a Gracey-type curette and ErL irradiation at a panel setting of 70 mJ/pulse and 20 Hz with sterile saline spray. After applying an enamel matrix derivative and autogenous bone grafting, ErL was used to form a blood clot coagulation on the grafted bone surface at 50 mJ/pulse and 20 Hz without water spray for approximately 30 seconds. Twelve months after surgery the mean probing depth had improved from 6.2 mm to 2.0 mm, the mean clinical attachment level had reduced from 7.5 mm to 3.4 mm, and bleeding on probing had improved from (+) to (-). Mean intrabony defect depth decreased from 6.0 mm before surgery to 1.0 mm 12 months after surgery. A novel procedure for periodontal regenerative surgery applying ErL irradiation for thorough decontamination during debridement as well as blood coagulation following autogenous bone grafting seems to have achieved favorable and stable healing of periodontal pockets with significant clinical improvement and desirable regeneration of angular bone defects, including one-wall defects.

    Full Text Available Dental treatment performed in patients receiving oral anticoagulant drug therapy is becoming increasingly common in dental offices.The aim of oral anticoagulant therapy is to reduce blood coagulability to an optimal therapeutic range within which the patient is provided some degree of protection from thromboembolic events. This is achieved at the cost of a minor risk of haemorrhage. Frequently raised questions concern the safety and efficacy of the various anticoagulation regimens and their accompanying thromboembolic and bleeding risks relative to invasive dental procedures.The aim of this literature review is to evaluate the available evidence on the impact of anticoagulant medications on dental treatment and highlight certain patient management issues closely interrelated to various aspects of dental treatment. For that purpose literature search in the electronic database of Medscape, Pubmed-Medline, Science Direct, and EBSCO host, in the data base of Medical University Plovdiv and specialised published books in general medicine and dentistry was made.A total of 33 publications between 1995 and 2013 were identified: 12 review articles, 11 randomized controlled and non-randomised studies, 6 guidelines and practical guides, 1 meta-analysis and 3 specialised books.

  20. Comparison of 3 different anesthetic techniques on 24-hour recovery after otologic surgical procedures.

    Jellish, W S; Leonetti, J P; Fahey, K; Fury, P


    Intravenous propofol anesthesia is better than inhalational anesthesia for otologic surgery, but cost and intraoperative movement make this technique prohibitive. This study compares a propofol sandwich anesthetic with a total propofol or inhalational anesthetic for otologic surgery to determine which produces the best perioperative conditions and least expense. One hundred twenty patients undergoing ear surgery were randomly chosen to receive an anesthetic with either isoflurane (INHAL), total propofol (TPROP), or propofol used in conjunction with isoflurane (PSAND). Postoperative wakeup and the incidence and severity of nausea, vomiting, and pain were compared among groups. Antiemetic administration and discharge times from recovery and the hospital were also compared. The groups were similar, but anesthesia times were longer in the INHAL group. Emergence from anesthesia after PSAND or TPROP was more rapid than after INHAL. Recovery during the next 24 hours was associated with less nausea and vomiting with PSAND than with INHAL. The cost of the PSAND anesthetic was similar to that of INHAL, and both were less than TPROP. PSAND anesthesia may be similar to TPROP and better than INHAL for otologic procedures. PSAND was less expensive than TPROP and produced a similar recovery profile and antiemetic effect in the 24-hour period after surgery. PMID:10064647

  1. Eating Disorders in obese patients seeking bariatric surgery: aspects of mental health before and afterweight-loss treatment

    Dahl, Jens Kornelius


    Background: An increasing number of obese patients are seeking surgical weight-loss treatments. Health-care workers need more knowledge about the various characteristics of these patients, and how they should be treated. Prior to bariatric surgery, those with Eating Disorders (EDs) showed impaired psychological functioning in several areas when compared with those without EDs. Some studies have shown that patients with EDs also have less success in the weight loss interventions. The present t...

  2. The influence of a eutectic mixture of lidocaine and prilocaine on minor surgical procedures: a randomized controlled double-blind trial.

    Shaikh, Faisal M


    BACKGROUND: A eutectic mixture of lidocaine and prilocaine (EMLA) has been shown to be effective in reducing pain from needle sticks, including those associated with blood sampling and intravenous insertion. OBJECTIVE: To evaluate the effectiveness of EMLA cream applied before needle puncture for local anesthetic administration before minor surgical procedures in this double-blind, randomized, controlled, parallel-group study. MATERIALS AND METHODS: Patients were randomly assigned to receive EMLA or placebo cream (Aqueous) applied under an occlusive dressing. After the procedure, patients were asked to rate the needle prick and procedure pain on a visual analog scale (0=no pain; 10=maximum pain). RESULTS: A total of 94 minor surgical procedures (49 in EMLA and 45 in control) were performed. The mean needle-stick pain score in the EMLA group was significantly lower than in the control group (2.7 vs. 5.7, p<.001, Mann-Whitney U-test). There was also significantly lower procedure pain in the EMLA group than in the control group (0.83 vs. 1.86, p=.009). There were no complications associated with the use of EMLA. CONCLUSION: EMLA effectively reduces the preprocedural needle-stick pain and procedural pain associated with minor surgical procedures.

    The U.S. Occupational Safety and Health Administration (OSHA) estimates that half a million health-care workers are exposed to laser surgical smoke each year. The purpose of this study was to establish a methodology to (1) estimate emission rates of laser-generated air contaminants (LGACs) using an emission chamber, and to (2) perform a screening study to differentiate the effects of three laser operational parameters. An emission chamber was designed, fabricated, and assessed for performance to estimate the emission rates of gases and particles associated with LGACs during a simulated surgical procedure. Two medical lasers (Holmium Yttrium Aluminum Garnet [Ho:YAG] and carbon dioxide [CO2]) were set to a range of plausible medical laser operational parameters in a simulated surgery to pyrolyze porcine skin generating plume in the emission chamber. Power, pulse repetition frequency (PRF), and beam diameter were evaluated to determine the effect of each operational parameter on emission rate using a fractional factorial design. The plume was sampled for particulate matter and seven gas phase combustion byproduct contaminants (benzene, ethylbenzene, toluene, formaldehyde, hydrogen cyanide, carbon dioxide, and carbon monoxide): the gas phase emission results are presented here. Most of the measured concentrations of gas phase contaminants were below their limit of detection (LOD), but detectable measurements enabled us to determine laser operation parameter influence on CO2 emissions. Confined to the experimental conditions of this screening study, results indicated that beam diameter was statistically significantly influential and power was marginally statistically significant to emission rates of CO2 when using the Ho:YAG laser but not with the carbon dioxide laser; PRF was not influential vis-a-vis emission rates of these gas phase contaminants.

    Gletsu-Miller, Nana; Wright, Breanne N.


    Moderate/severe obesity is on the rise in the United States. Weight management includes bariatric surgery, which is effective and can alleviate morbidity and mortality from obesity-associated diseases. However, many individuals are dealing with nutritional complications. Risk factors include: 1) preoperative malnutrition (e.g., vitamin D, iron); 2) decreased food intake (due to reduced hunger and increased satiety, food intolerances, frequent vomiting); 3) inadequate nutrient supplementation ...

    Background: The actual gold standard technique for obesity treatment is the Roux-en-Y gastric bypass. However, complications may occur and the surgeon must be prepared for them. Aim: To evaluate retrospectively the complications occurrence and associated factors in patients who underwent bariatric surgery. Methods: In this study, 469 medical charts were considered, from patients and from data collected during outpatient consultations. The variables considered were gender, age, height, pre-ope...

  6. New devices for the bariatric patient.

    Debergh, Isabelle; Snauwaert, Christophe; Dillemans, Bruno


    Over the past years, the global prevalence of obesity has risen dramatically. This generates enormous costs for the health care system, since obesity is associated with hypertension, diabetes mellitus type 2, coronary heart diseases, stroke, dyslipidemia, psychological problems, and cancer. Bariatric surgery has demonstrated to be the most effective and durable treatment option in the morbidly obese patient. Despite its evidence based efficacy, less than 1% of obese patients will undergo surgery. The role of new, less-invasive devices for the bariatric patient needs to be defined. Are they situated in the gap between lifestyle modification and surgery for the obese patient, in the preoperative work-up of the super-obese patient, in patient groups that are currently excluded for surgery, and/or in the routine treatment of obesity as a chronic disease? This review will focus on emerging technologies for the bariatric patient that are currently in clinical practice or in an advanced development stage, with different modes of action: inducing stretch on the gastric wall (space-occupying or stitching devices), vagal neuromodulation, altering the absorption, or exclusion of the duodenum and proximal jejunum. Exploring the evidence and the indication of different therapeutic approaches and innovations will be an interesting field of research in the near future. PMID:26923812

  7. Persistently High Hip Circumference after Bariatric Surgery Is a Major Hurdle to Successful Hip Replacement

    Menachem M. Meller; Courville, Amber B; Sumner, Anne E.


    The prevalence of class III obesity (BMI ≥ 40 kg/m2) in black women is 18%. As class III obesity leads to hip joint deterioration, black women frequently present for orthopedic care. Weight loss associated with bariatric surgery should lead to enhanced success of hip replacements. However, we present a case of a black woman who underwent Roux-en-Y gastric bypass with the expectation that weight loss would make her a better surgical candidate for hip replacement. Her gastric bypass was success...

  8. The Bariatric Patient in the Intensive Care Unit: Pitfalls and Management.

    Pompilio, Carlos E; Pelosi, Paolo; Castro, Melina G


    The increasing number of bariatric/metabolic operations as important alternatives for the treatment of obesity and type 2 diabetes brought several concerns about the intensive care of patients undergoing those procedures. Intensive Care Unit admission criteria are needed in order to better allocate resources and avoid unnecessary interventions. Furthermore, well-established protocols, helpful in many clinical situations, are not directly applicable to obese patients. Indeed, difficult airway management, mechanical ventilation, fluid therapy protocols, prophylaxis, and treatment of venous thromboembolic events have unique aspects that should be taken into consideration. Finally, new data related to planning nutrition therapy of the critically obese have been highlighted and deserve consideration. In this review, we provide an outline of recent studies related to those important aspects of the care of the bariatric/metabolic patients in critical conditions. PMID:27464648

  10. Surgical efficiencies and quality in the performance of voluntary medical male circumcision (VMMC procedures in Kenya, South Africa, Tanzania, and Zimbabwe.

    Dino Rech

    Full Text Available INTRODUCTION: This analysis explores the association between elements of surgical efficiency in voluntary medical male circumcision (VMMC, quality of surgical technique, and the amount of time required to conduct VMMC procedures in actual field settings. Efficiency outcomes are defined in terms of the primary provider's time with the client (PPTC and total elapsed operating time (TEOT. METHODS: Two serial cross-sectional surveys of VMMC sites were conducted in Kenya, Republic of South Africa, Tanzania and Zimbabwe in 2011 and 2012. Trained clinicians observed quality of surgical technique and timed 9 steps in the VMMC procedure. Four elements of efficiency (task-shifting, task-sharing [of suturing], rotation among multiple surgical beds, and use of electrocautery and quality of surgical technique were assessed as explanatory variables. Mann Whitney and Kruskal Wallis tests were used in the bivariate analysis and linear regression models for the multivariate analyses to test the relationship between these five explanatory variables and two outcomes: PPTC and TEOT. The VMMC procedure TEOT and PPTC averaged 23-25 minutes and 6-15 minutes, respectively, across the four countries and two years. The data showed time savings from task-sharing in suturing and use of electrocautery in South Africa and Zimbabwe (where task-shifting is not authorized. After adjusting for confounders, results demonstrated that having a secondary provider complete suturing and use of electrocautery reduced PPTC. Factors related to TEOT varied by country and year, but task-sharing of suturing and/or electrocautery were significant in two countries. Quality of surgical technique was not significantly related to PPTC or TEOT, except for South Africa in 2012 where higher quality was associated with lower TEOT. CONCLUSIONS: SYMMACS data confirm the efficiency benefits of task-sharing of suturing and use of electrocautery for decreasing TEOT. Reduced TEOT and PPTC in high volume
