RESUMEN

Objective: The increasing global prevalence of obesity, coupled with its association with chronic health conditions and rising healthcare costs, highlights the need for effective interventions; however, despite the availability of treatment options, the ongoing success of primary interventions in maintaining long-term weight loss remains limited. This study examined the prescription medication dispensing changes following sleeve gastrectomy in Australians aged 45 years and over. Methods: In a retrospective analysis of 847 bariatric surgery patients from the New South Wales 45 and Up Study, the assessment of medication patterns categorizing into three groups: gastrointestinal, metabolic, cardiorespiratory, musculoskeletal, and nervous systems was conducted. Each drug class was analyzed, focusing on patients with dispensing records within the 12 months before surgery. This study employed interrupted time-series analysis to compare pre- and post-surgery medication usage. Results: With a predominantly female population (76.9%) and an average age of 57.2 (standard deviation 5.71), there were statistically significant reductions in both unique medications (12.5% decrease, p = 0.004) and total medications dispensed (15.9% decrease, p = 0.003) from 12 months before surgery to 13-24 months after bariatric surgery. All medication categories, except opioids, showed reductions. Notably, the most significant reductions were observed in diabetes (38.6%), agents acting on the renin-angiotensin system (40.4%), lipid modifying agents (26.5%), anti-inflammatory products (46.3%), and obstructive airway diseases (53.3%) medications during this time frame. Conclusion: These findings suggest that sleeve gastrectomy provides an effective therapeutic intervention for patients with comorbidities requiring multiple medications, especially for obesity-related diseases such as diabetes, cardiovascular, respiratory and musculoskeletal disorders.

RESUMEN

Hernia occurs when the peritoneum and/or internal organs penetrate through a defect in the abdominal wall. Implanting mesh fabrics is a common way to reinforce the repair of hernia-damaged tissues, despite the risks of infection and failure associated with them. However, there is neither consensus on the optimum mesh placement within the abdominal muscles complex nor on the minimum size of hernia defect that requires surgical correction. Here we show that the optimum position of the mesh depends on the hernia location; placing the mesh on the transversus abdominis muscles reduces the equivalent stresses in the damaged zone and represents the optimum reinforcement solution for incisional hernia. However, retrorectus reinforcement of the linea alba is more effective than preperitoneal, anterectus, and onlay implantations in the case of paraumbilical hernia. Using the principles of fracture mechanics, we found that the critical size of a hernia damage zone becomes severe at 4.1 cm in the rectus abdominis and at larger sizes (5.2-8.2 cm) in other anterior abdominal muscles. Furthermore, we found that the hernia defect size must reach 7.8 mm in the rectus abdominis before it influences the failure stress. In other anterior abdominal muscles, hernia starts to influence the failure stress at sizes ranging from 1.5 to 3.4 mm. Our results provide objective criteria to decide when a hernia damage zone becomes severe and requires repair. They demonstrate where mesh should be implanted for a mechanically stable reinforcement, depending on the type of hernia. We anticipate our contribution to be a starting point for sophisticated models of damage and fracture biomechanics. For example, the apparent fracture toughness is an important physical property that should be determined for patients living with different obesity levels. Furthermore, relevant mechanical properties of abdominal muscles at various ages and health conditions would be significant to generate patient specific results.

RESUMEN

Obesity is a complex and multifactorial chronic disease with genetic, environmental, physiological and behavioural determinants that requires long-term care. Obesity is associated with a broad range of complications including type 2 diabetes, cardiovascular disease, dyslipidaemia, metabolic associated fatty liver disease, reproductive hormonal abnormalities, sleep apnoea, depression, osteoarthritis and certain cancers. An algorithm has been developed (with PubMed and Medline searched for all relevant articles from 1 Jan 2000-1 Oct 2021) to (i) assist primary care physicians in treatment decisions for non-pregnant adults with obesity, and (ii) provide a practical clinical tool to guide the implementation of existing guidelines (summarised in Appendix 1) for the treatment of obesity in the Australian primary care setting. MAIN RECOMMENDATIONS AND CHANGES IN MANAGEMENT: Treatment pathways should be determined by a person's anthropometry (body mass index (BMI) and waist circumference (WC)) and the presence and severity of obesity-related complications. A target of 10-15% weight loss is recommended for people with BMI 30-40 kg/m2 or abdominal obesity (WC > 88 cm in females, WC > 102 cm in males) without complications. The treatment focus should be supervised lifestyle interventions that may include a reduced or low energy diet, very low energy diet (VLED) or pharmacotherapy. For people with BMI 30-40 kg/m2 or abdominal obesity and complications, or those with BMI > 40 kg/m2 a weight loss target of 10-15% body weight is recommended, and management should include intensive interventions such as VLED, pharmacotherapy or bariatric surgery, which may be required in combination. A weight loss target of > 15% is recommended for those with BMI > 40 kg/m2 and complications and they should be referred to specialist care. Their treatment should include a VLED with or without pharmacotherapy and bariatric surgery.

RESUMEN

Patient blood management (PBM) offers significantly improved outcomes for almost all medical and surgical patient populations, pregnant women, and individuals with micronutrient deficiencies, anemia, or bleeding. It holds enormous financial benefits for hospitals and payers, improves performance of health care providers, and supports public authorities to improve population health. Despite this extraordinary combination of benefits, PBM has hardly been noticed in the world of health care. In response, the World Health Organization (WHO) called for its 194 member states, in its recent Policy Brief, to act quickly and decidedly to adopt national PBM policies. To further support the WHO's call to action, this article addresses 3 aspects in more detail. The first is the urgency from a health economic perspective. For many years, growth in health care spending has outpaced overall economic growth, particularly in aging societies. Due to competing economic needs, the continuation of disproportionate growth in health care spending is unsustainable. Therefore, the imperative for health care leaders and policy makers is not only to curb the current spending rate relative to the gross domestic product (GDP) but also to simultaneously improve productivity, quality, safety of patient care, and the health status of populations. Second, while PBM meets these requirements on an exceptional scale, uptake remains slow. Thus, it is vital to identify and understand the impediments to broad implementation. This includes systemic challenges such as the so-called "waste domains" of failure of care delivery caused by malfunctions of health care systems, failure of care coordination, overtreatment, and low-value care. Other impediments more specific to PBM are the misperception of PBM and deeply rooted cultural patterns. Third, understanding how the 3Es-evidence, economics, and ethics-can effectively be used to motivate relevant stakeholders to take on their respective roles and responsibilities and follow the urgent call to implement PBM as a standard of care.

RESUMEN

BACKGROUND: On November 25, 2021, the IFSO-Asia-Pacific Chapter (IFSO-APC) Virtual Meeting 2021 was held online, and the representatives from the Asia-Pacific region presented 10 years of change in bariatric/metabolic surgery and the influence of COVID-19 in the special session of "IFSO-APC National Reports 2010-2020". We herein report the summarized data. METHODS: National bariatric/metabolic surgery data, which included the data of 2010 and 2020, were collected from the representatives using a questionnaire that consisted of 10 general questions. At the congress, the data were calculated and summarized. RESULTS: Thirteen of the 14 national societies responded to the survey. From 2010 to recent years, the populations of individuals with obesity (BMI ≥ 30 kg/m2) and individuals with diabetes both significantly increased. Eight countries and regions expanded the lower limit of criteria for bariatric surgery by 2-5 kg/m2 (BMI), and 5 countries newly established criteria for metabolic surgery in the last ten years. Sixty-nine percent of the countries currently run public health insurance systems, which doubled from 2010. The number of bariatric surgeons and institutions increased more than threefold from 2010. In 2010, 2019, and 2020, surgeons in IFSO-APC societies performed 18,280, 66,010, and 49,553 bariatric/metabolic surgeries, respectively. Due to the COVID pandemic, restriction policies significantly reduced access to surgery in South and Southeast Asian countries. The biggest changes included increased numbers of bariatric surgeons and institutions, operation numbers, public insurance coverage, raising awareness, and national registry systems. CONCLUSION: For the last 10 years, bariatric/metabolic surgery has rapidly grown in the Asia-Pacific region.

RESUMEN

BACKGROUND/OBJECTIVE: During multiple organ procurement, blood vessels are routinely retrieved and stored in University of Wisconsin solution and then discarded after two weeks, if not used at organ transplantation owing to lack of a method for long-term preservation. Therefore, the aim of this study is to investigate a method for long-term preservation of vascular allografts in ethanol. METHODS: Aorta and vena cava allografts were retrieved and stored in 75% ethanol solution for 12 months at 4°C. Four pigs were divided into two groups. A segment of aorta was excised and replaced by insertion of preserved aorta graft (Group A) or vena cava graft (Group V). The pigs were observed for six weeks. A laparotomy was performed and the vascular graft was harvested for histopathology followed by euthanasia at the end of study. RESULTS: Three pigs recovered uneventfully, while one pig died from venous graft rupture in the third week after surgery. There was no aneurysmal formation or thrombosis in the grafts. Some calcification was seen over aorta allograft. On histopathology, the elastic pattern was almost normal, although the endothelial cells degenerated after preservation. After implantation, the formation of the endothelium cell-like layer was seen in both aorta and vena cava allografts. CONCLUSION: Vascular allografts were functional after preservation for 12 months. The vena cava grafts had much less wall calcification than the aorta grafts. Further studies are necessary to investigate vascular graft remodelling with a longer observation period after implantation.

RESUMEN

BACKGROUND: The performance of laparoscopic sleeve gastrectomy has increased markedly to become the single-most performed bariatric surgical procedure globally. To date, a means of standardized trainee teaching has not been developed. The aim of this study was to design a laparoscopic curriculum for trainees of bariatric surgery utilizing modified Delphi consensus methodology. METHODS: A panel of surgeons was assembled to devise an academic framework of technical, non-technical and cognitive skills utilized in the performance of laparoscopic sleeve gastrectomy. The panel invited 18 bariatric surgeons experienced in laparoscopic gastrectomy from 11 countries to rate the items for inclusion in the curriculum to a predefined level of agreement. RESULTS: A consensus of experts was achieved for 24 of the 30 proposed elements for inclusion within the first round of the curriculum Delphi panel. All components pertaining to anatomical knowledge, peri-operative considerations and non-technical items were accepted. A second round further examined six statements, of which three were accepted. Agreement of the panel was reached for 27 of the cognitive, technical and non-technical components after two rounds. Three statements found no consensus. CONCLUSIONS: Utilizing modified Delphi methodology, a curriculum outlining the most important components of teaching the procedure of laparoscopic sleeve gastrectomy, has been determined by a consensus of international experts in bariatric surgery. The curriculum is suggested as a standard in proficiency-based training of this procedure. It forms a generic template which facilitates individual jurisdictions to perform content validation, adapting the curriculum to local requirements in teaching the next generation of bariatric surgeons.

RESUMEN

PURPOSE: The global rise in obesity has been accompanied by widespread uptake of the procedure of laparoscopic sleeve gastrectomy. Despite this, the key components for performance assessment have not been standardized for this procedure. The aim of this study was to develop and demonstrate the validity of a Sleeve Objective Structured Assessment of Technical Skill (SOSATS) scale for learning the procedure of laparoscopic sleeve gastrectomy (LSG). MATERIALS AND METHODS: The SOSATS evaluation tool was based upon critical steps of the LSG procedure. Both the SOSATS and the Global Rating Scale (GRS) component of the Objective Structured Assessment of Technical Skill (OSATS) tools were utilized in a prospective single-blinded observational study design of 26 video recordings of surgeons performing sleeve gastrectomies using a novel simulation. The surgeons were allocated into "novice" or "experienced" groups dependent on case-volume criteria. Surgical performance was assessed using both the GRS and SOSATS scales by blinded assessors of the video recordings. RESULTS: Face and content validity were demonstrated for key components of the simulated model. An overall positive correlation was established inferring concurrent validity between the accepted OSATS Global Rating Scale against the SOSATS procedural scale. Construct validity was established for a number of areas of the SOSATS scale. CONCLUSION: The SOSATS scale is shown to exhibit construct and concurrent validity in the simulated setting for the procedure of sleeve gastrectomy. Utilizing this scale to review surgical performance is potentially feasible and reliable but would require further research prior to use in high-stakes assessment processes such as credentialing.

RESUMEN

BACKGROUND: In 2016, a preoperative clinic was implemented to screen, evaluate, and manage anemia and suboptimal iron stores at a major tertiary care medical center in Western Australia. Few studies compare the costs and reimbursements associated with preoperative anemia and suboptimal iron stores management. The objective of our study was to conduct a net cost analysis associated with the implementation of this clinic. METHODS: We designed a retrospective cohort study involving elective colorectal surgical admissions over a 3-year period. The baseline year selected was the 2015-2016 financial year, with outcomes in the 2016-2017 and 2017-2018 year compared to baseline. The study perspective was the Western Australian Health System. Hospital costs were extracted from the health service clinical costing system, which captures costs at the admission level. The primary outcome was net cost, defined as gross cost minus reimbursement (or funding) received. RESULTS: Our 3-year study included 544 admissions for elective colorectal surgery. After the implementation of the preoperative clinic, 73.4% (n = 257) of admissions were screened for anemia and suboptimal iron stores, and 31.4% (n = 110) received intravenous iron. In our adjusted analysis, when comparing the final year (2017-2018) with baseline (2015-2016), the units of red blood cells transfused per admission decreased 53% (142 vs 303 units per 1000 discharges; P = .006), and mean hospital length of stay decreased 15% (7.7 vs 9.1 days; P = .008). When comparing the final year with baseline, rectal resection admissions were associated with a mean decrease in the net cost of Australian dollar (A$) 7619 (95% confidence interval, 4230-11,008; P < .001) between 2015-2016 and 2017-2018. For small and large bowel procedures, there was a mean decrease of A$6744 (95% confidence interval, 2430-11,057; P = .002). CONCLUSIONS: The implementation of a preoperative anemia and suboptimal iron stores screening and management clinic in elective colorectal surgery was associated with reductions in red cell transfusions, length of stay, and net costs.

RESUMEN

The World Health Organization (WHO) has declared coronavirus disease 2019 (COVID-19), the disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a pandemic. Global health care now faces unprecedented challenges with widespread and rapid human-to-human transmission of SARS-CoV-2 and high morbidity and mortality with COVID-19 worldwide. Across the world, medical care is hampered by a critical shortage of not only hand sanitizers, personal protective equipment, ventilators, and hospital beds, but also impediments to the blood supply. Blood donation centers in many areas around the globe have mostly closed. Donors, practicing social distancing, some either with illness or undergoing self-quarantine, are quickly diminishing. Drastic public health initiatives have focused on containment and "flattening the curve" while invaluable resources are being depleted. In some countries, the point has been reached at which the demand for such resources, including donor blood, outstrips the supply. Questions as to the safety of blood persist. Although it does not appear very likely that the virus can be transmitted through allogeneic blood transfusion, this still remains to be fully determined. As options dwindle, we must enact regional and national shortage plans worldwide and more vitally disseminate the knowledge of and immediately implement patient blood management (PBM). PBM is an evidence-based bundle of care to optimize medical and surgical patient outcomes by clinically managing and preserving a patient's own blood. This multinational and diverse group of authors issue this "Call to Action" underscoring "The Essential Role of Patient Blood Management in the Management of Pandemics" and urging all stakeholders and providers to implement the practical and commonsense principles of PBM and its multiprofessional and multimodality approaches.

RESUMEN

Kartagener syndrome is a rare autosomal recessive condition. Approximately 25% of those with situs inversus totalis suffer the syndrome. With the rising overall number and indications for bariatric surgery, this condition will be increasingly recognised. We present a case of a 25-year-old woman with SIT and Kartagener syndrome who underwent a laparoscopic sleeve gastrectomy. As with all bariatric surgery, a multidisciplinary team approach was important in managing such a case. There were considerable cognitive challenges for the surgical team both preoperatively and during the procedure. The patient tolerated the operation well and was discharged 2 days after the surgery. At 12-months follow-up, the patient had achieved 125% excess weight loss. This case illustrates that an experienced surgeon can safely perform a laparoscopic sleeve gastrectomy on a patient with situs inversus totalis.

RESUMEN

BACKGROUND: The technical proficiency of a surgeon is intricately linked to training and experience. Reduction in working hours, decreased operating time and ethical imperatives to protect patients have all resulted in a decrease in hands-on experience. The introduction of laparoscopic procedures has also decreased trainees' exposure to open operative procedures not routinely performed in the current era. METHODS: The Clinical Training and Evaluation Centre at The University of Western Australia introduced the Core Skills Workshop for general surgical trainees in 2007. The workshop provides cadaveric dissection time for a range of open procedures. We describe in this article the logistics of setting up and running a cadaveric workshop, the performance and report our trainees' evaluation of the workshop. RESULTS: The Clinical Training and Evaluation Centre has hosted 26 General Surgery Core Skills Workshops since 2007. There were 227 participants with 196 evaluations returned (response rate 86%). Feedback was strongly positive for the course meeting the participants' expectations as well as its contribution to their skillset. Participants value the use of cadavers and high instructor:student ratios along with performance of a large number of open procedures in the setting of a stress-free workshop and looked forward to more similar courses in the future. CONCLUSIONS: Fresh frozen cadaver workshops are of value in the face of current surgical training challenges in providing an efficient, effective and safe environment.

RESUMEN

INTRODUCTION: It is unclear whether low levels of alcohol are harmful in patients with non-alcoholic fatty liver disease (NAFLD). We aimed to determine whether quantity, binge pattern consumption, or type of alcohol was associated with liver fibrosis in patients with NAFLD. METHODS: Previous and current alcohol consumption was assessed in NAFLD patients undergoing liver biopsy. All subjects currently consumed <210 g per week (male) or <140 g per week (female). Binge consumption was defined as ≥4 standard drinks (female) or ≥5 standard drinks (male) in one sitting. Liver biopsies were scored according to the NASH CRN system with F3/4 fibrosis defined as advanced. RESULTS: Among 187 patients (24% with advanced fibrosis), the median weekly alcohol consumption was 20 (2.3-60) g over an average of 18 years. Modest consumption (1-70 g per week) was associated with lower mean fibrosis stage compared to lifetime abstainers (p < 0.05) and a decreased risk of advanced fibrosis (OR 0.33, 95% CI 0.14-0.78, p = 0.01). The association with reduced fibrosis was not seen in subjects drinking in a binge-type fashion. Exclusive wine drinkers but not exclusive beer drinkers, had lower mean fibrosis stage and lower odds of advanced fibrosis (OR 0.20, 95% CI 0.06-0.69, p = 0.01), compared to lifetime abstinent subjects. No interaction between gender and alcohol quantity, type, or binge consumption on fibrosis was observed. DISCUSSION: Modest (1-70 g per week) alcohol consumption, particularly wine in a non-binge pattern, is associated with lower fibrosis in patients with NAFLD. Prospective longitudinal studies into fibrosis progression, cardiovascular outcomes, and mortality are required before clinical recommendations can be made.

RESUMEN

AIMS: To explore participants' ability to participate in physical activity (PA), and barriers and facilitators to PA, at 12 months following restrictive bariatric surgery, and how these differed from participants' pre-surgery perceptions. Motivators for PA post-surgery were also explored. METHODS: Qualitative one-on-one in-depth interviews were conducted pre- and 12 months post-surgery. Data were analysed using inductive thematic analysis. RESULTS: Fourteen adults (12 females), with a mean (range) age of 41.4 years (25.0-56.0), body mass index (BMI) of 31.7kg/m2 (22.3-48.2), and excess weight loss of 66% (2-127) completed both interviews. Lack of participation in PA during the first 3-6 months post-surgery was a common theme. Although participants reported increased ability to participate in PA, attributing this to a reduction in obesity-related physical barriers to PA, many participants reported that some pre-surgery obesity-related barriers to PA remained at 12 months post-surgery. For most participants, pre-surgery non-obesity related barriers to PA also remained at 12 months post-surgery. Facilitators to PA were consistent pre- and post-surgery. Weight loss and improvement in physical appearance were the most common motivators for PA post-surgery. CONCLUSIONS: At 12 months following surgery, many participants reported residual obesity and non-obesity related barriers to PA. These barriers may explain the small, if any, pre- to post-surgery change in PA levels reported by earlier research. Facilitators to PA did not change and post-surgery motivators for PA were mostly esteem-related. These data are relevant to shape interventions aimed at optimising PA in this population.

RESUMEN

Background and aims: TLR9 deletion protects against steatohepatitis due to choline-amino acid depletion and high-fat diet. We measured TLR9 in human non-alcoholic steatohepatitis (NASH) livers, and tested whether TLR9 mediates inflammatory recruitment in three murine models of non-alcoholic fatty liver disease (NAFLD). Methods: We assayed TLR mRNA in liver biopsies from bariatric surgery patients. Wild-type (Wt), appetite-dysregulated Alms1 mutant (foz/foz), Tlr9-/-, and Tlr9-/-foz/foz C57BL6/J mice and bone marrow (BM) chimeras were fed 0.2% cholesterol, high-fat, high sucrose (atherogenic[Ath]) diet or chow, and NAFLD activity score (NAS)/NASH pathology, macrophage/neutrophil infiltration, cytokines/chemokines, and cell death markers measured in livers. Results: Hepatic TLR9 and TLR4 mRNA were increased in human NASH but not simple steatosis, and in Ath-fed foz/foz mice with metabolic syndrome-related NASH. Ath-fed Tlr9-/- mice showed simple steatosis and less Th1 cytokines than Wt. Tlr9-/-foz/foz mice were obese and diabetic, but necroinflammatory changes were less severe than Tlr9+/+.foz/foz mice. TLR9-expressing myeloid cells were critical for Th1 cytokine production in BM chimeras. BM macrophages from Tlr9-/- mice showed M2 polarization, were resistant to M1 activation by necrotic hepatocytes/other pro-inflammatory triggers, and provoked less neutrophil chemotaxis than Wt Livers from Ath-fed Tlr9-/- mice appeared to exhibit more markers of necroptosis [receptor interacting protein kinase (RIP)-1, RIP-3, and mixed lineage kinase domain-like protein (MLKL)] than Wt, and ∼25% showed portal foci of mononuclear cells unrelated to NASH pathology. CONCLUSION: Our novel clinical data and studies in overnutrition models, including those with diabetes and metabolic syndrome, clarify TLR9 as a pro-inflammatory trigger in NASH.

RESUMEN

OBJECTIVES: There are increased reports that kidney transplant can be performed by laparoscopic surgery. The further development of this technique could revolutionize human kidney transplant surgery. However, laparoscopic kidney transplant demands a high level of skill for vascular anastomoses. The emerging technology of the three-dimensional, high-definition laparoscopic system may facilitate the application of this technique. Therefore, in this study, we evaluated this system in performing kidney transplant surgery versus the two-dimensional laparoscopic system. MATERIALS AND METHODS: Four fresh-frozen human cadavers were used in this study, with 2 for the 3-dimensional and 2 for the 2-dimensional system. Kidneys were retrieved by using the retroperitoneoscopic technique for living donor nephrectomy from the same cadaver. The kidney graft was transplanted at the right iliac fossa using a laparoscopic technique by extraperitoneal approach. The procedure was recorded, and the vessel anastomotic time was analyzed. RESULTS: Kidney transplant procedures were conducted successfully in the 3-dimensional, high-definition and the 2-dimensional groups. We recorded no significant differences in terms of vessel anastomotic time between the 2 groups. The total surgery time was shorter in the 3-dimensional, high-definition group than in the 2-dimensional group (P = .02). CONCLUSIONS: This pilot study reinforces that kidney transplant with either the 3-dimensional, high-definition or 2-dimensional laparoscopy is feasible in a human cadaveric model. The operation was the same as open kidney transplant, but the procedure was performed by a laparoscopic approach with a smaller incision.

RESUMEN

Perforation of a marginal ulcer (MU) is a complication of Roux-en-Y gastric bypass that can be life-threatening. We report a case of a perforated MU that presented 7 months after surgery with several interesting points for discussion. Firstly, the presentation of the ulcer was cryptic with unreliable investigations. Secondly, the ulcer presented again even after anastomotic revision surgery. Finally, the ulcer and the sepsis associated with perforation presented after months of poor nutritional intake with profound hypoalbuminaemia. Perforated MUs causing malnutrition pose clinicians with the difficult decision of which operation to offer; patch repair, revision of the anastomosis or reversal surgery. This case illustrates that primary reversal surgery for a perforated recurrent MU may be the most appropriate surgical management in this clinical situation.
