Malabsorptive Surgery - The Laparoscopic Gastric Bypass |
|
|
The Gastric bypass is approved by the American Association of Bariatric Surgeons and by the National Institute of Health as the recommended procedure for weight loss surgeries and also recommended as the most successful procedure for excess weight loss and for long term weight control. This surgery combines both restriction and malabsorption; this surgery is the option currently elected by the majority of Bariatric surgeons in the United States and in some Countries of Latin America. We have had interesting results in patients where we have performed the Larrad Gastric Bypass.
The advantage of this type of surgery is that we have obtained results of better control regarding malabsorption and of the diarrheas with or without the annoying flatulence.
Gastric bypass studies show that some patients with more than 15 years of post - surgery maintain their excess weight loss in 75%. Now, with the modern refinement of the surgery, there are many patients who lose from 85% to 100% of their excess weight and maintain it without regaining the lost weight.
With laparoscopic surgery a mini camera and all specialized surgical instruments to perform the procedure are introduced in the abdomen through five or six trocars inserted in small incisions. Trough these is where the extraction, sectioning, stapling, cutting, and intestinal unions are performed. This gives the surgeon a better viewing of the anatomy and a better access to the dominant anatomical parts. The most modern technology gives the surgical team the ability to operate with precision and safety.
 The idea is that the endoscopic image projected is 20 times larger in the monitor, reason why many surgical procedures, be it sectioning or unions becomes much easier than with conventional surgery, and at the same time obtaining the added benefits of the laparoscopy.
Compared to Open Surgery, Laparoscopic Surgery offers better results. A recent study showed that those patients who underwent Laparoscopy Weight Loss Surgery have experienced less pain after surgery. This results in easier breathing, a higher oxygenation level and a faster and better healing. There are also just few complications of the wounds such as infections or hernias and patients return to their normal activity levels in less time.

The diet that we recommend our patients to follow after the Laparoscopic Gastric Bypass Surgery is a diet that turns normal in short time, as long as the patients adapt to their diets some of the suggestions that we detail below.
Patients should eat three small meals per day, without drinking liquids with their meals. This way the small stomach created won't retain liquids and solids at the same time. All the liquids must be calorie free. The diet will essentially have to be rich in proteins; meat, fish, egg, or cheese free of fat, as well as: vegetables, fresh fruits and salads. Fats and sugar should be avoided as much as possible, and carbohydrates must be chiefly in the form of fruits or of vegetables.
It is possible that intolerance to lactose be developed after undergoing the Gastric bypass surgery. This means that products like milk or derivates of the same, such as cheese, can cause flatulence and/or diarrhea. This is not very common, but can be handled easily by avoiding these foods or using products to replace Lactulose.
Another post operative symptom caused by the Gastric Bypass surgery is that certain foods cannot be absorbed in a regular manner. Specifically, these can be liposoluble vitamins: vitamins A, D, and, K, iron, calcium and vitamin B12. It is because of this situation that we recommend to continually take multivitamins with minerals, as well as additional iron, and calcium. |

The risks and complications are similar to a Gastric Sleeve surgery, but the difference in this procedure is that in this surgery connections take place (Anastomosis), that increases in an important way the risk of fistulas, along with the consequent complications to this eventuality; even more so if the surgical team does not have enough experience in performing these procedures.
We have a team of surgeons of connoted experience; this affirmation is confirmed by the almost 500 bariatric procedures of all types performed, which guarantee that the performance of any of the techniques will include the corresponding safety measures in order to prevent the eventualities previously mentioned.
Choosing the Gastric Bypass as an alternative in any one patient is because said patient qualifies for this procedure, which reaffirms the fact that the group has the experience to perform the technique, as well as have the experience to manage the post operative issues that were mentioned in detail in previous paragraphs. |

The Gastric Bypass is considered the Gold Standard by the American Group. The restrictive procedures also imply a progressive diet to break in the new Gastric pouch and so that the intestinal physiology gradually establishes patterns of metabolic behavior that will not originate any serious damage, but to the contrary, a progressive adaptation to the balanced diets is seen with the corresponding limitations in carbohydrates, fats and change in eating habits.
As with every mayor surgery, this one is not exempt of the complications that were previously explained; these risks are obviously diminished when groups like ours, include people with vast experience in the mentioned procedures.
The parallel medical problems will improve in a significant way, particularly in patients with Diabetes Type 2. As is described before, the duodenal exclusion of the food tract lessens the presence of hormones such as PG1 and others and substantially helps this group of patients to even stop using Insulin and taking Oral Hypoglycemic agents, the Cardiovascular condition will also improve as well as the auricular conditions.
Additionally, regarding the procedure, the surgery is performed using a laparoscopic technique, with the use of 5 or 6 incisions. The average surgery time is between 2 and 2.5 hours. The time of hospitalization is normally not more than 3 days, and as standard practice we always add a "drain" in the abdomen for any eventuality. Symptomatics are used for pain that is generally not bothersome. Patients recover from this surgery quickly and are released with a calculated modular diet for roughly about 3 weeks while the Gastric pouch heals and we adequate to this physiological change of the intestine. |
