The document summarizes research on the rise of obesity in the United States and treatment options. It finds that over the last two decades, about two-thirds of Americans are overweight or obese. While diet and medication are often ineffective long-term, bariatric surgery has been shown to significantly help with weight loss and resolution of related health conditions like diabetes and hypertension. The risks and outcomes of different bariatric procedures like Roux-en-Y gastric bypass and sleeve gastrectomy are discussed.
Bariatric surgery by Dr B D Soni, army hospital Drbd Soni
This document discusses various types of bariatric surgery procedures for treating obesity. It begins by defining bariatric surgery and obesity classifications. It then covers criteria for surgery candidacy and contraindications. The main sections describe restrictive procedures like gastric banding and sleeve gastrectomy, malabsorptive procedures, and combination/mixed procedures like Roux-en-Y gastric bypass. For each procedure, it provides details on how it works to induce weight loss and potential complications. Pre- and post-operative considerations are also reviewed.
This document discusses weight regain after bariatric surgery and options for revisional surgery. It notes that 50% of patients regain some weight within 2 years of bariatric surgery. Evaluation of weight regain involves assessing patient factors like diet, lifestyle, and medical issues. Revisional surgery depends on the primary procedure and patient characteristics. Options presented include pouch resizing, band adjustment or removal, converting to a different procedure like sleeve gastrectomy or Roux-en-Y gastric bypass. While revisional surgery can provide further weight loss, risks are generally higher than primary procedures and long-term outcomes require more study. Careful patient evaluation and multidisciplinary support are important.
Bariatric surgery is effective for treating morbid obesity. Common procedures include gastric bypass and gastric banding, which achieve weight loss through restriction and malabsorption. Candidates must have a BMI over 40 or over 35 with comorbidities. Risks include leaks and DVTs. Weight loss improves related conditions like diabetes. Plastic surgery after significant weight loss addresses excess skin.

This document discusses bariatric and metabolic surgery. It begins by defining morbid obesity and listing its causes and health risks. It then outlines the steps in treating morbid obesity, including pharmacotherapy, diet/exercise, and bariatric surgery. Several types of bariatric surgeries are described, including restrictive, malabsorptive, and combined procedures. Potential complications are listed. The document also discusses how bariatric surgery can help treat and potentially cure diabetes and other obesity-related diseases by altering gut hormones like GLP-1 and PYY.
This document discusses metabolic surgery, which aims to cure or improve metabolic syndrome through gastrointestinal procedures like gastric bypass and sleeve gastrectomy. Metabolic syndrome is defined by conditions like elevated blood glucose, blood pressure, triglycerides, and reduced HDL cholesterol. These surgeries have been shown to significantly resolve type 2 diabetes in many patients through mechanisms involving changes in gastrointestinal hormones and adipokines independent of weight loss. Complications from metabolic surgeries are generally minor, with mortality rates below 1% showing it is a highly safe and effective treatment when lifestyle changes fail to control metabolic syndrome and diabetes.
Bariatric & Metabolic Surgery : Then & Nowniket shah
Bariatric surgery is an effective treatment for severe obesity and related comorbidities. There are several surgical procedures that work via restriction of food intake, malabsorption, or a combination. The Roux-en-Y gastric bypass is considered the gold standard but sleeve gastrectomy is now the most commonly performed due to its effectiveness and fewer nutritional deficiencies. While bariatric surgery is generally safe, complications can include leaks, infections, nutritional deficiencies requiring lifelong supplementation, and internal hernias. Newer minimally invasive techniques such as endoscopic procedures are being developed to provide alternatives to traditional surgery.
This document provides information on bariatric surgery. It begins with definitions of bariatric and discusses the increasing prevalence of bariatric procedures over time. It then covers topics like the causes and pathophysiology of obesity, degrees of obesity based on BMI, obesity-related comorbidities, options for treatment like diet, drugs and surgery. It provides details on various bariatric surgical procedures that are either restrictive, malabsorptive or a combination. Risks, guidelines for candidacy, pre and post-op care are discussed. In summary, the document is a comprehensive overview of bariatric surgery, its increasing use and role in treating severe obesity and related health conditions.
This document discusses endoscopic management of obesity, known as endobariatrics. It can be used as primary therapy, bridging therapy before surgery, or revisional therapy after surgery. Primary endoscopic therapies include intragastric balloons, tissue apposition techniques, and nutrient diverting therapies. Secondary endoscopic therapies include transoral outlet reduction, revision obesity surgery procedures, and argon plasma coagulation. Several studies on intragastric balloons and other primary therapies show promising results with 20-50% excess weight loss. Endobariatrics aims to bridge the gap between medical and surgical obesity treatment.
This document summarizes the surgical treatment of morbid obesity. It discusses the prevalence and health risks of obesity, indications for bariatric surgery, the evolution of different surgical procedures like gastric bypass and gastric banding, and results showing significant long-term weight loss and reduction in obesity-related health conditions with bariatric surgery. Laparoscopic bariatric surgery procedures like Roux-en-Y gastric bypass and adjustable gastric banding are now commonly performed and have been shown to be safe and effective options for treating morbid obesity.
Recent advances in bariatric surgery include the development of minimally invasive procedures like mini gastric bypass and endoscopic interventions. Obesity is a growing global epidemic that increases the risk of chronic diseases and mortality. Bariatric surgery procedures have become more common and effective treatments for severe obesity, led by laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass. Newer procedures and endoscopic techniques aim to provide weight loss benefits with less risk and invasiveness than traditional bariatric surgery.
This document discusses bariatric surgeries including laparoscopic sleeve gastrectomy (LSG) and laparoscopic adjustable gastric banding (LAGB). It defines morbid obesity and the criteria for who needs bariatric surgery. It describes the mechanisms of action, preoperative evaluation, operative procedures, postoperative care, outcomes and complications of LSG and LAGB. LSG involves dividing the stomach along the greater curvature to create a tubular sleeve while LAGB places an adjustable band around the top of the stomach to restrict intake. Both aim to induce weight loss through restriction of food intake.
The document discusses obesity, its causes, measurements, classifications, and treatments including metabolic/bariatric surgery. It defines obesity as a chronic disease influenced by genetics and environment. Surgical treatments include restrictive procedures like gastric banding and sleeve gastrectomy, as well as malabsorptive procedures like Roux-en-Y gastric bypass and biliopancreatic diversion that restrict food intake and interfere with nutrient absorption. The goal of metabolic surgery is to achieve significant and long-term weight loss and improve medical comorbidities beyond just diet and lifestyle changes.
1. Bariatric surgery, such as gastric bypass and sleeve gastrectomy, can lead to high rates of remission or improvement of type 2 diabetes by altering gut hormone levels and increasing insulin sensitivity.
2. Clinical guidelines recommend bariatric surgery for adults with a BMI over 40, or between 35-40 with other obesity-related health conditions, when non-surgical weight loss efforts have failed.
3. Pre-operative risk stratification is important to reduce risks, and bariatric surgery may be a first-line treatment option for diabetes instead of lifestyle/drug interventions.
Bariatric surgery is the most effective treatment for obesity, resulting in greater weight loss than diet and exercise alone. The three most common bariatric surgery procedures are sleeve gastrectomy, Roux-en-Y gastric bypass, and adjustable gastric banding. Sleeve gastrectomy and Roux-en-Y gastric bypass typically result in 60-70% excess weight loss, while gastric banding results in less weight loss of around 50%. Bariatric surgery significantly improves or resolves obesity-related conditions like type 2 diabetes, hypertension, and sleep apnea. Complications can include leaks, strictures, nutritional deficiencies, and gallstones, but can often be managed endoscopically.
Bariatric surgery can help treat obesity and related health conditions through restrictive and malabsorptive techniques. Key hormonal changes may contribute to reduced appetite and improved metabolism. Specifically, surgeries like Roux-en-Y gastric bypass and sleeve gastrectomy may lower levels of the appetite-stimulating hormone ghrelin in the short term. Long-term nutritional deficiencies are less common with restrictive procedures but still require monitoring and supplementation. Bariatric surgery has been shown to resolve or improve conditions like diabetes, hypertension, and sleep apnea in the majority of patients.
This document discusses treatment strategies for gastric cancer, including surgery, endoscopic resection, and guidelines. It addresses topics such as the appropriate extent of lymph node dissection, whether to perform total or subtotal gastrectomy, when multi-organ resection may be necessary, and comparisons of open versus laparoscopic surgery. Palliative interventions like gastrojejunostomy or stenting are also evaluated. The document emphasizes individualizing treatment based on cancer stage and location, with the goal of an R0 resection while minimizing treatment-related morbidity.
The document discusses the mini-gastric bypass (MGB) procedure for weight loss surgery. It provides the background and experience of Dr. Rutledge, who has performed over 6,000 MGB cases. It outlines criteria for an "ideal" weight loss surgery and argues that the MGB meets more of these criteria than other procedures like Roux-en-Y gastric bypass and gastric banding. Specifically, it notes the MGB's low risk, significant weight loss, ease of performance, and minimal complications like marginal ulcers. The document ultimately concludes the MGB is the best choice for weight loss surgery based on meeting objectives and success criteria.
Bariatric surgery is gaining popularity worldwide. The number of surgeries has increased by almost 10 times in the last decade and almost 14000 bariatric surgery were performed last year in India.
This document provides an overview of bariatric surgery in Odisha, India. It begins with definitions of bariatric surgery and classifications of BMI. It then discusses the comorbidities of obesity and guidelines for determining who is a suitable candidate for bariatric surgery. The document outlines various bariatric procedures including restrictive, malabsorptive, and combination procedures. It also discusses pre-op assessment, investigations, tools used in bariatric surgery, pathophysiology including the role of GI hormones, and videos demonstrating sleeve gastrectomy and Roux-en-Y gastric bypass procedures.
Morbid obesity is diagnosed using body mass index, body fat percentage, and waist circumference measurements. Treatment involves lifestyle changes including diet, exercise, and behavior therapy as well as medications or surgery. Surgical options include restrictive procedures like gastric banding and sleeve gastrectomy, or combined restrictive and malabsorptive procedures like Roux-en-Y gastric bypass. Complications can include leaks, infections, nutritional deficiencies, and weight regain, so patients require long-term management. Bariatric surgery is effective for treating obesity-related medical conditions and promoting significant and sustainable weight loss for eligible patients.
Bariatric surgery is currently the only effective treatment for sustained weight loss in patients with morbid obesity. The document discusses various bariatric procedures including laparoscopic adjustable gastric banding, sleeve gastrectomy, Roux-en-Y gastric bypass, and biliopancreatic diversion. It covers the indications, contraindications, preoperative evaluation and preparation, types of procedures, postoperative care, advantages, disadvantages, and complications of different bariatric surgeries. The goal of bariatric surgery is to improve health in morbidly obese patients by achieving long-term weight loss through caloric intake reduction and malabsorption.

What are the unique endocrinologic issues which explain the mechanism of success with bariatric surgery? Learn here.
This document discusses bariatric surgery as a treatment for diabetes. It notes that 240 million people worldwide currently have diabetes, a number expected to rise to 380 million by 2025. Bariatric surgeries like gastric banding, sleeve gastrectomy, and gastric bypass can result in significant and sustained weight loss, leading to remission of type 2 diabetes in 80% of patients. Both short-term changes in gut hormones and long-term changes in adipose tissue and adipokines contribute to improved glucose control after weight loss surgery. The author has received training in bariatric procedures and now regularly performs sleeve gastrectomies at their hospital to treat diabetes.
NAFLD is a common liver disease affecting 10-24% of the general population globally. It ranges from simple steatosis to non-alcoholic steatohepatitis (NASH) which is characterized by steatosis, lobular inflammation, and hepatocyte damage. Risk factors include obesity, diabetes, hyperlipidemia, and metabolic syndrome. Lifestyle modifications including weight loss through diet and exercise are the first-line treatment. Newer potential drug therapies target various disease mechanisms but require further study. Bariatric surgery can significantly improve or resolve NAFLD and related comorbidities in obese patients.

An Overview of Bariatric Surgery- shaheed.pptxShaheedAlaamry2
This document provides an overview of bariatric surgery. It discusses that obesity is a major global health problem, causing over 4 million premature deaths annually. It reviews the different types of bariatric surgeries performed, including gastric bypass, sleeve gastrectomy, gastric banding, and discusses their effectiveness and risks. It also covers pre and post-operative nutrition considerations, potential complications, and the significant health benefits of bariatric surgery, such as resolution of diabetes and other comorbidities, as well as improvements in quality of life.
This document provides information about bariatric/metabolic surgery and what patients should know. It discusses why weight loss is important for improving health and quality of life. The goals of surgery are lower body weight, improved quality of life, reduced morbidity, and cost effectiveness. Different types of operations are described, including gastric band, gastric bypass, and sleeve gastrectomy. Expected weight loss is 25-30% of excess weight long term. Surgery resolves many obesity-related health conditions and complications are rare. Close follow up is required after surgery. Surgery is now being considered as a treatment for type 2 diabetes and other metabolic conditions even in patients with mild obesity.
Is There a Role for Surgery in the Treatment of DiabetesGeorge S. Ferzli
1. Bariatric surgery has been shown to significantly improve or resolve type 2 diabetes and other obesity-related conditions through mechanisms beyond just weight loss, such as changes in gut hormones.
2. Studies in animal models and humans found that bypassing parts of the small intestine can improve glucose control, independently of weight loss, through changes in hormones like GLP-1, GIP, leptin and others.
3. The mechanisms are not fully understood but likely involve bypassing the duodenum and proximal jejunum to alter gut hormone signaling and glucose metabolism.
This document discusses anesthesia considerations for bariatric surgery. It defines obesity and lists common comorbidities like diabetes and hypertension. Bariatric surgery procedures aim to induce weight loss and resolve medical conditions. Risks include respiratory complications from reduced lung capacity and obesity hypoventilation syndrome. Preoperative evaluation assesses the airway, cardiovascular and pulmonary systems, sleep apnea risk, and use of weight loss medications. Polysomnography is used to diagnose sleep apnea severity.
The document discusses anesthesia considerations for bariatric surgery. It notes that obesity is associated with various comorbidities affecting the respiratory, cardiovascular, gastrointestinal and other body systems. The anesthesia plan involves a thorough preoperative evaluation of the patient's airway, cardiac function, respiratory status, risk of venous thromboembolism, and metabolic/nutritional abnormalities. Careful dosing of anesthetic drugs based on lean or total body weight is also required. The goal of anesthesia is to safely induce and maintain anesthesia for bariatric surgery while addressing the unique health risks faced by obese patients.
This document discusses various treatment options for obesity including diet, exercise, medications, surgery, and other procedures. It provides details on popular diets, weight loss programs, appetite suppressing medications, medications that reduce absorption like Orlistat, and newer combination medications. It describes various bariatric surgeries including gastric banding, bypass, and newer procedures. Potential complications of surgery are outlined including nutritional deficiencies, dumping syndrome, gallstones, and risks are balanced with significant weight loss and health benefits shown in long term studies.
The document discusses non-alcoholic fatty liver disease (NAFLD) and its relationship to metabolic syndrome.

Robotic surgery - advantages and disadvantagesJohn Thanakumar
Robotic surgery offers several advantages over traditional surgery. It allows surgeons to perform complex procedures with more precision, flexibility and control through the use of robotic arms. The surgeon sits at a console to control the robotic arms, which provide 3D vision and small, precise movements. For patients, this translates to less pain, fewer complications, shorter hospital stays and faster recovery times. However, robotic surgery also has some disadvantages like higher costs and a continued need for humans in the operating room.

1. Rectal injuries are becoming a major cause of death in India and can result from penetrating or blunt trauma.
2. The rectum has distinct anatomical regions and injuries are classified based on their depth and circumference according to the American Association for the Surgery of Trauma scale.
3. Treatment depends on whether the injury is intraperitoneal or extraperitoneal and may involve fecal diversion, distal washout, drainage, debridement, and repair or reconstruction of damaged sphincters. Accurate diagnosis and classification is important to guide appropriate surgical management of rectal injuries.
Recurrence of Symptoms after Heller's myotomy- ACHALASIAJohn Thanakumar
1. Surgical treatment for achalasia fails in 10-20% of patients due to recurrence of symptoms after surgery.
2. The main causes of recurrence after Heller's myotomy are incomplete myotomy at the lower esophageal sphincter and upper esophageal sphincter as well as fibrosis.
3. Treatment options for recurrence include pneumatic dilatation, repeat laparoscopic Heller's myotomy, per oral endoscopic myotomy, botulinum toxin injection, esophagectomy, and laparoscopic esophagogastrostomy.
This document provides an overview of the surgical anatomy of the esophagus. It discusses the embryology, structure, and applied anatomy of the esophagus in the neck, thorax, and abdomen. Key points include that the esophagus deviates left in the neck but is midline in the thorax and curves left in the abdomen. It describes the layers of the esophagus including the external fibrous layer, muscular layer, submucosal layer, and mucosal layer. It also discusses the arterial supply, venous drainage, lymphatic drainage, and nerve supply of the esophagus.
Surgeons can be categorized into different groups based on their attitudes towards surgical innovations:
- The true revolutionists develop new methods and are willing to die for their ideas if needed.
- The true intellectuals carefully assess innovations and are willing to abandon them if found to be false or unsupported by evidence.
- The profiteers join any revolution to gain advantages like prestige or money, whether the innovation is valid or not.
- The reactionaries resist all changes and prefer the status quo, while the counter-revolutionists fight innovations they believe are dangerous or misguided.
This document discusses the reuse of disposable laparoscopic instruments. It notes that while manufacturers recommend single use, instruments can be safely reused through a rigorous cleaning and sterilization process. This includes mechanical cleaning, chemical cleaning with enzymes, ultrasonic cleaning, and sterilization with hydrogen peroxide vapor or ethylene oxide. A 2004 study of 125 laparoscopic procedures found no differences in outcomes when single-use disposables were reused after sterilization with glutaraldehyde. Reusing instruments can provide significant cost savings for hospitals while reducing plastic waste. Proper cleaning, sterilization, and inspection of instruments is required to ensure safety when reusing disposables.
This document provides tips to prevent recurrence in laparoscopic hernia repair. It discusses choosing the appropriate mesh based on patient factors like smoking or obesity. Lightweight meshes have benefits like less inflammation and pain but higher risk of recurrence. The document outlines proper surgical techniques like fully dissecting the hernia sac and surrounding tissues, using an appropriately sized mesh that is securely fixed in place and covers the defect. Adhering to best practices for anatomy display, limitations awareness, advanced skills and standardized dissection principles can help minimize recurrence risk.

Comparison of bariatric to metabolic surgery
1. Metabolic Surgery compared
to Bariatric Surgery
Dr PRAVIN JOHN MS
Dr John Thanakumar MS,MNAMS, FRCS
Dept of Advanced Laparoscopy & Bariatric Surgery
ANURAG HOSPITAL, Coimbatore.
·www.anuraghospital.com
2. OBESITY
Second only to smoking as a preventable cause of
death
Major morbidity and mortality
5. Obesity in India
Obesity has increased in India in 21 century, with
morbid obesity affecting 5% of population
Indians are genetically susceptible to weight
accumulation especially around the waist
10. Metabolic Syndrome
Abdominal obesity and girth
Decreased high-density lipoprotein
Increased insulin resistance
Increased diabetic state
Increased high blood pressure
11. Diseases associated with obesity
Diabetes mellitus(Type 2)
Obstructive sleep apnea (OSA)
Coronary ischemic disease
Hypertension
Some cancers
Osteoarthritis
Also early death
12. Metabolic Syndrome
Common
More in abdominal obesity
More in advanced with age( 60 years)
Men commonly than women
South Asians appear more susceptible
Metabolic syndrome on drugs e.g. steroids, antidepressants
and antipsychotic agents.
13. Metabolic Surgery
Why the nomenclature?
· Bariatric Surgery is involved with weight loss
· Results and mechanism went beyond weight loss
· Hence the term Metabolic surgery
· 2002 Primary intent to cure Type 2 DM (T2DM)
Francesco Rubino
14. Term - Metabolic Surgery
· Acceptance after a landmark “Diabetes Surgery Summit” in
2007.
· 2 world congresses dedicated subject and statements of
relevant organizations, notably the International Diabetes
Federation in 2011.
15. Not for Low BMIs
“Metabolic” and “diabetes surgery”, however, incorrectly
referred to as a surgical approach to treat diabetes in low
BMI patients, as a set of novel and yet experimental
operations.
16. Differences between bariatric
& metabolic surgery
Metabolic surgical patients have a more balanced
male/female ratio, showed higher incidence of type 2
diabetes, hypertension, dyslipidemia, higher cardiovascular
risk & established cardiovascular disease at onset
17. Definition of Metabolic Surgery
Metabolic Surgery is defined as “a set of gastrointestinal
operations used with the intent to treat diabetes ("diabetes
surgery") and metabolic dysfunctions (which include
obesity)”
· Surgery to treat T2DM in patients with BMI above 35
should be considered “metabolic/diabetes surgery” not
“bariatric surgery”.
18. T2DM & OBESITY
· The primary risk factor for Type 2 Diabetes Mellitus is obesity
· 90% of all patients with type 2 diabetes are overweight or obese.
· Risk of diabetes increases about 42-fold in men as the BMI increases
from <23 kg/m2 to >35 kg/m2 & 93-fold in women as BMI increases
from <22 kg/m2 to >35 kg/m2 .
Diabetes Care 1994
N Engl J Med 2001
19. Benefits of Obesity Surgery
Diabetes improved in more than 85% of patients and cured in
more than 75% overall
Cholesterol -70% improved after surgery
Hypertension cured in 60% of patients and improved in
more than 18%.
Sleep Apnoea cured in 85.7% of surgical patients.
20. Other Advantages of Obesity Surgery
Improvement with fatty infiltration of liver
Improvement in respiratory function and asthmatic
symptoms
Reversal of mild cardiomyopathy of obesity
Improvement in joint pain and mobility
21. Who cannot have Obesity surgery?
Severe uncontrolled heart disease
Uncontrolled psychiatric disorder, Low IQ
Inability to follow instructions
Drug abuse, and cancer
23. Adjustable Gastric Band
Common in Europe, Australia& S.America.
Small gastric pouch(15 mL).
Weight loss is about 50-60% of excess body weight in 2 years.
24. Early Complications of Band
Injury of the stomach or esophagus
Bleeding
Food intolerance (most common)
Wound infection
Pneumonia
25. Late Complications of Gastric Band
Food intolerance or noncompliance to band (13%)
Band slippage (stomach prolapse) (2.2-8%)
Pouch dilatation
Band erosion into the stomach
Port complications
Re operation rate (2-41%)
Esophageal dilatation
Failure to lose weight
Port infection, band infection
Leakage of the balloon or tubing
Mortality rate (0.5%; 0% in some series)
27. Laparoscopic Sleeve Gastrectomy
Sleeve gastrectomy employs subtotal gastric resection to reduce
stomach to 15-20% of its original size
The mechanism related to gastric restriction or to Grehlin
changes
Initially first of 2-stage op;with simplicity & favorable outcomes
Now a primary, stand-alone procedure.
Wt loss 33-83% of excess weight. Physiologic operation
29. Lap Roux en Y Gastric Bypass
Gastric pouch ( 20 ml) and small outlet cause sensation of satiety
& grehlin.
Malabsorption is adjusted by length of the alimentary and bilio
pancreatic limbs.
The malabsorptive element bypasses the distal stomach,
duodenum, and some of the jejunum.
The standard Roux limb is 75cm. Long gastric bypass is150cm and
the last is a very long-limb (distal gastric bypass).
30. Result of Gastric Bypass
Weight loss 65-70% of excess body weight
Long-limb bypasses give comparable weight reductions in
super obese (BMI >50 kg/m2) pts.
Weight loss generally levels off in 1-2 years.
31. Early Complications of
Roux en Y Gastric Bypass
Anastomotic leak (1-3%)
Pulmonary embolism, deep vein thrombosis (<1%)
Wound infection (more common with open approach)
Gastrointestinal hemorrhage, bleeding (0.5-2%)
Respiratory insufficiency, pneumonia
Acute distention of the distal stomach
32. Late Complications of
Gastric Bypass
Stomal stenosis, most common (20%)
Bowel obstruction, small bowel obstruction (1%)
Internal hernia
Cholelithiasis
Micronutrient deficiencies
Marginal ulcer
Staple line disruption
Ventral hernia formation
Marginal Ulcer
33. Mortality of Gastric Bypass
Operative (30-day) mortality is about 0.5%.
Less the experience, more the complications
Compared with open procedures, laparoscopy has a higher rate
of intra-abdominal complications
35. Meta analysis- DM +Obesity
