What are the differences as regards other anti-obesity operations?

Roux’s Y Gastric Bypass.

It is frequently used. It has two anastomosis because not only the stomach is cut but also the intestine. It causes a mesenteric defect related to 2%-5% of intestinal obstruction symptoms in which patient is necessarily operated again (this problem is avoided with the bypass of one anastomosis because it isn't necessary to cut the intestine). Furthermore, between 5% and 10% of patients develop a stenosis in the connection between the stomach and intestine that must be treated by endoscopy or even, in extreme cases, reoperating.

This type of operation always lets the food pass through a part of intestine before it is mixed with the bile (that let the food digestion), this event, that never happens in normal people, causes problems in intestinal mucus and the patient doesn't feel very well (these symptoms have been checked in studies of experimentation with animals by our professional group). The weight loss kept in long-term is fewer with this operation than with bypass of one anastomosis we use (this fact is proved in our controlled studies).

Vertical Ringed Gastroplasty.

Until nineties this operation was the most performed one in Europe in order to treat Morbid Obesity. It is similar to Gastric Bypass because it is necessary the same stomach reduction. This operation can be performed by open surgery or laparoscop.

The difference is that in Gastroplasty it also puts a ring round the way out the new stomach in order to limit its emptying whereas in the Gastric Bypass of one Anastomosis we always connect the stomach with a intestine segment at about the middle of the way between the stomach and colon.

The main problems are frequent vomiting and the contact between the reduced stomach and the rest of the stomach which causes that the patient puts on weight again.

The weight loss is considerably fewer than with the Gastric Bypass and most of patients put on weight after 2 years.

Banda Gastric Band.

It is similar to Gastroplasty but it is always performed by laparoscopy. It doesn’t need staples but a silicon band which causes the stomach reduction.

It causes about 10% of reoperations because of different problems with the Band round the stomach (it can move from the place it was put, it can move into the stomach, the stomach can expand, etc).

Furthermore the weight loss is considerably fewer than with the Gastric Bypass.

Bile pancreatic Bypass.

It is a more traumatic and serious operation, and it was performed when Vertical Ringed Gastroplasty was a common operation in which very obese patients put hardly lose weight, that’s why it was necessary a more serious operation in order to get them to lose weight.

The difference as regards the Gastric Bypass of one Anastomosis is that in Bile pancreatic Bypass it is removed (it is cut off and extracted) half the stomach, it is left almost all the intestine only to lead bile, it is connected a intestine segment between the stomach and colon and digestion begins when bile and food mix. Digestion is only done into an intestine segment between 50 and 100 cm.

The main problems are not only a serious increase in operation risk because of the great trauma it causes but also after being operated, the patient needs go to the toilet between 4 and 10 times a day for life and defecations are very foul-smelling. Furthermore a high percentage of patients have problems related to the lack of proteins and calcium that are the cause of bone decalcifications (this happens because of the little intestine the patient still has got to absorb food nutrients).

Duodenal Connection.

It is an operation very similar to Bile pancreatic Bypass, and it can be considered a variant of the second, because essence is the same and the only difference is the connection between the stomach and intestine.

Duodenal Connection Gastric Bypass of One Anastomosis

The difference is that in Duodenal Connection it is removed (it is cut off and extracted) half the stomach in a vertical and not horizontal way in order that the connection between the stomach and intestine is more similar to the normal one.

The main problems are the same that we explained when we spoke about Bile pancreatic Bypass.
