One Anastomosis
Steps Involved in IVF:
Procedure Description
One Anastomosis Gastric Bypass (OAGB), also known as mini-gastric bypass, is a type of bariatric surgery aimed at helping patients with obesity to lose weight and improve obesity-related conditions such as type 2 diabetes, hypertension, and sleep apnea. It involves creating a smaller stomach pouch to limit food intake and rerouting part of the small intestine to alter the digestion process. This combination of restriction and malabsorption helps patients achieve significant weight loss by reducing calorie intake and nutrient absorption.
The procedure begins with the creation of a long, narrow gastric pouch along the lesser curvature of the stomach. Unlike the traditional Roux-en-Y gastric bypass (RYGB), which requires two connections (anastomoses), the OAGB involves a single anastomosis. The new stomach pouch is connected directly to a loop of the small intestine, bypassing a portion of the digestive tract. This simplifies the surgical process while still providing effective weight loss results.
OAGB has become increasingly popular due to its relatively simpler surgical technique, reduced operative time, and promising outcomes. Patients undergoing this procedure often experience significant and sustained weight loss, along with improvements in metabolic conditions and overall quality of life. However, like all surgical interventions, OAGB requires a comprehensive understanding of the risks, benefits, and long-term lifestyle changes involved.
Procedure Duration
The One Anastomosis Gastric Bypass surgery typically lasts between 60 to 90 minutes, which is shorter than many other bariatric procedures due to its single anastomosis technique. The duration of the surgery is also influenced by factors such as the patient's medical history, body mass index (BMI), and any underlying health conditions that could add complexity to the procedure.
During the procedure, patients are placed under general anesthesia. The surgeon performs the surgery laparoscopically, using small incisions and specialized instruments. Once the new stomach pouch is created and connected to the small intestine, the surgical team ensures that all connections are secure and there are no leaks before completing the operation. The less invasive laparoscopic approach usually results in reduced scarring, decreased postoperative pain, and shorter hospital stays.
Recovery from OAGB can vary. Most patients stay in the hospital for 2 to 4 days post-surgery. Initial recovery time, where patients gradually progress from a liquid diet to solid foods, usually takes around 4 to 6 weeks. Full recovery, with patients adapting to new eating habits and lifestyle changes, can take several months. Patients are also required to follow a structured postoperative care plan, including nutritional support, physical activity, and regular follow-up appointments to monitor weight loss progress and health improvements.
Benefits
- Effective Weight Loss: OAGB often leads to significant weight loss, with patients typically losing 60-80% of their excess body weight within 12 to 18 months.
- Simpler Surgical Technique: The single anastomosis reduces operating time and surgical complexity compared to RYGB, resulting in fewer complications.
- Improvement of Metabolic Disorders: Conditions such as type 2 diabetes, hypertension, and sleep apnea often show marked improvement or remission following the procedure.
- Faster Recovery: The minimally invasive laparoscopic approach leads to a shorter hospital stay, reduced postoperative pain, and quicker recovery time.
- Potential Reversibility: Unlike some bariatric procedures, OAGB can be reversed or revised if necessary, although this is usually considered a last resort.

With a focus on quality care and patient comfort, Spain is a popular destination for medical tourists from across Europe and beyond, seeking OAGB with experienced surgeons in a relaxed environment.
Risks & Considerations
- Nutrient Deficiency: Due to the bypassing of a portion of the small intestine, patients may face malabsorption of vital nutrients such as iron, calcium, vitamin B12, and protein, requiring long-term supplementation.
- Dumping Syndrome: Rapid gastric emptying can cause "dumping syndrome," characterized by nausea, diarrhea, abdominal cramps, and dizziness when consuming sugary or high-fat foods.
- Bile Reflux: OAGB patients may experience bile reflux, as the procedure allows bile to flow back into the stomach and esophagus, leading to discomfort and potential complications.
- Anastomotic Leak: Although rare, there is a risk of leaks at the surgical site where the stomach pouch is connected to the small intestine, which can lead to serious infections and require further surgical intervention.
- Weight Regain: As with any bariatric surgery, there is a possibility of weight regain if patients do not adhere to postoperative dietary guidelines and lifestyle changes.
How to Choose the Right Doctor and Hospital
When considering One Anastomosis Gastric Bypass surgery, selecting the right doctor and hospital is paramount to ensuring a safe and successful outcome. It's important to choose a bariatric surgeon with extensive experience in performing OAGB, as well as accreditation from reputable medical boards. Look for surgeons who have undergone specialized training in bariatric surgery and have a proven track record of successful patient outcomes.
The hospital or clinic chosen should be equipped with modern facilities, support staff trained in bariatric care, and access to comprehensive preoperative and postoperative services. Transparency in discussing potential risks, benefits, and realistic expectations of the surgery is crucial for patient confidence and informed decision-making. Additionally, facilities that offer medical tourism support services, such as travel coordination, accommodation assistance, and language support, can greatly enhance the overall experience for international patients.

Frequently Asked Questions
What actually happens during hyperstimulation of the ovaries?
The patient will take injectable FSH (follicle stimulating hormone) for eight to eleven days, depending on how long the follicles take to mature. This hormone is produced naturally in a woman’s body causing one egg to develop per cycle. Taking the injectable FSH causes several follicles to develop at once, at approximately the same rate. The development is monitored with vaginal ultrasounds and following the patient’s levels of estradiol and progesterone. FSH brand names include Repronex, Follistim, Menopur, Gonal-F and Bravelle. The patient injects herself daily.
What happens during egg retrieval?
When the follicles have developed enough to be harvested, the patient attends an appointment where she is anesthetized and prepared for the procedure. Next, the doctor uses an ultrasound probe to guide a needle through the vaginal wall and into the follicle of the ovary. The thin needle draws the follicle fluid, which is then examined by an embryologist to find the eggs. The whole process takes about 20 minutes.
What happens to the eggs?
In the next step, the harvested eggs are then fertilized. If the sperm from the potential father, or in some cases, anonymous donor, has normal functionality, the eggs and sperm are placed together in a dish with a nutrient fluid, then incubated overnight to fertilize normally. If the sperm functionality is suboptimal, an embryologist uses Intracytoplasmic Sperm Injection to inject a single sperm into a single egg with an extremely precise glass needle. Once fertilization is complete, the embryos are assessed and prepared to be transferred to the patient’s uterus.
How are the embryos transferred back to the uterus?
The doctor and the patient will discuss the number of embryos to be transferred. The number of successfully fertilized eggs usually determines the number of eggs to be placed in the uterus. Embryos are transferred to the uterus with transabdominal ultrasound guidance. This process does not require anesthesia, but it can cause minor cervical or uterine discomfort. Following transfer, the patient is advised to take at least one days bed rest and two or three additional days of rest, then 10 to 12 days later, two pregnancy tests are scheduled to confirm success. Once two positive tests are completed, an obstetrical ultrasound is ordered to show the sac, fetal pole, yolk sac and fetal heart rate.
Embryoscope©
Built into this technology there is a microscope with a powerful camera that allows the uninterrupted monitoring of the embryo during its first hours of life. In this way, we can keep a close eye on the embryo, from the moment when the oocyte is inseminated and begins to divide into smaller and smaller cells, until it can be transferred to the uterus.
