Use of ERAS Protocols in Bariatric Surgery

Introduction:

The bariatric surgery requirements are primarily the body weight of individuals over 100 pounds. Beginning with perioperative evidence-based therapies for colorectal procedures, a group of European surgeons originally outlined the enhanced recovery after surgery (ERAS) protocol. ERAS aims to accelerate the process and provide safe, superior postoperative care (fast-track surgery). The main idea behind the ERAS protocol is to address various issues that may arise during surgical therapy using a multimodal and interdisciplinary approach. Fast-track postoperative recovery programs, or ERAS, have been implemented for various surgical procedures, including cardiothoracic and other intra-abdominal surgeries. In ERAS protocols, anesthesia management is also suggested.

What Is Bariatric Surgery?

Bariatric surgery is a branch of surgery that includes several types of gastrointestinal surgeries that are helpful for obese individuals to lose weight. The types of bariatric surgery treatments include sleeve gastrectomy (along the greater curvature, 70 to 80 percent of the stomach is removed), gastric banding (band around the stomach upper part to hold food), gastric bypass or Roux-en-Y gastric bypass (a small pouch from the stomach is interlinked to the newly created pouch to the intestine), and biliopancreatic diversion (portions of the stomach are removed), is intended to decrease food intake. Significant weight loss and the improvement of the comorbidities associated with obesity, such as type 2 diabetes, hypertension, and dyslipidemia (lipids abnormal level in blood), can be accomplished with bariatric surgery. These processes function by limiting food intake, causing poor absorption of dietary calories, and leading to hormonal shifts. Bariatric surgery is regarded as a long-lasting and successful way to lose significant weight and enhance general health results. The reasons not to have bariatric surgery are pulmonary embolism, gallstones, excess skin, infection, bleeding, and peptic ulcer disease.

What Are the ERAS Protocols in Bariatric Surgery?

Preoperative Period:

The following actions are advised by the ERAS protocols typically begin during the preoperative phase:

• Preoperative education, counseling, and information.

• Prehabilitation and exercise.

• Quitting alcohol and smoking.

• Preoperative weight loss.

• Glucocorticoids.

• Cutting back on preoperative fasting.

• Carbohydrate loading.

The key elements emphasized in the initial preoperative phase are reduced fasting, oral carbohydrate loading, and multimodal pre-anesthesia medicine. It is generally well-recognized that preoperative fasting and carbohydrate loading reduce perioperative insulin resistance and metabolic decline. However, extra care must be taken to prevent aspiration during the induction of anesthesia because there is disagreement about the use of this technique in patients suffering from gastric reflux disease and diabetic neuropathy. Studies have indicated that carbohydrate loading does not increase the risk of aspiration in individuals after Roux-en-Y gastric bypass.

Intraoperative Period:

During the operation, the following are the principal elements of the ERAS program:

• The tenth and ninth steps in the anesthetic process are prophylactic care for postoperative normal oxygen ventilation, perioperative fluid management, standardized anesthetic protocol, ventilator techniques, neuromuscular block, monitoring of anesthetic depth, laparoscopy, nasogastric tube, and abdominal drainage.

• The ASMBS (American Society for Metabolic and Bariatric Surgery) guidelines also address goal-directed fluid management, protective breathing methods, conventional intraoperative anesthetic pathway, postoperative nausea and vomiting prophylaxis, and regional block. Appropriate anesthetic regimes and minimally invasive surgical techniques are crucial for a quick recovery following bariatric surgery.

• The keystones of intraoperative ERABS are goal-directed hydration management and pharmaceutical regimes designed to avoid postoperative nausea and vomiting (PONV).

Postoperative Period:

• Following surgery, the following actions are advised: Postoperative analgesia, thromboprophylaxis (prevention of clot formation), postoperative oxygenation, timely postoperative feeding, and non-invasive positive pressure breathing.

• Early ambulation and recuperation are the main goals of conventional postoperative multimodal treatment. Since PONV and pain are the primary causes of delayed recovery and diet, preventing PONV and using multimodal analgesia are crucial strategies for postoperative ERAS care to meet this goal.

• The ERAS program is a multidisciplinary treatment approach based on evidence that aims to maintain physiological function, improve mobilization, lessen pain, enable early nutrition, and lessen the stress associated with perioperative surgery. Early, safer, and more convenient recovery following surgery is the ultimate aim of the ERAS program, as it encourages an early return to society. Several fundamental protocol principles necessitate implementing multiple multimodal and multi-timing strategies to accomplish these objectives. The following are the ERAS protocol's guiding principles. 1) Patient education; 2) multimodal pain management options sparing opioids; 3) prophylactic treatment for PONV; 4) goal-directed hydration therapy; and 5) perioperative reduction of insulin resistance and catabolism.

What Are the Uses of ERAS Protocols in Bariatric Surgery?

• Promising findings have improved perioperative outcomes in numerous surgical specialties, including bariatric surgery, with enhanced recovery after surgery (ERAS) protocols. These protocols require multidisciplinary teamwork.

• Numerous investigations have revealed the advantages of incorporating ERAS procedures in bariatric surgery. Reduced hospital stays, quick patient turnover, shorter operative room stays, and cheaper healthcare expenses have all been linked to these guidelines. According to a meta-analysis of trials comparing ERAS with traditional bariatric surgery, the ERAS group's duration of stay was 1.56 days shorter on average. A different study found that the application of an ERAS strategy was found to shorten hospital stays from 4.7 to 2.1 days.

• Furthermore, ERAS methods have been demonstrated to maximize resource use and enhance patient satisfaction.

• Even though using ERAS protocols in bariatric surgery has shown promising results, there are a few things to remember. When ERAS is used, minor problems might increase, but average patient morbidity will not be significantly impacted. It is crucial to remember that ERAS methods in bariatric surgery are still not standardized, and more randomized trials contrasting ERAS with traditional care are required to bring the results together.

• It has been demonstrated that using ERAS procedures in bariatric surgery can improve perioperative results, such as shortened hospital stays, lower medical expenses, and higher patient satisfaction. However, more study is necessary to create standardized procedures and assess the effect of ERAS on certain problems and long-term outcomes in bariatric surgery.

Conclusion:

A bariatric surgery diet and ERAS protocols are essential. ERABS is an important therapeutic approach for prompt and secure recovery following bariatric surgery. Numerous components are suggested before, during, and after the surgery. However, not every ERABS element is supported by solid research. Additional research and clinical investigations are necessary to enhance recovery after surgery.
