Important Details About Laparoscopic Gastric Bypass Surgery

Laparoscopic Gastric Bypass Surgery is a variation of the usual gastric bypass or Roux-en-Y operation. The procedure makes use of a laparoscope, which is a great advantage for the surgeon and the patient as well. There are important details that an individual should know about Laparoscopic Gastric Bypass Surgery before he or she should decide to undergo it. The procedure, advantages, risks, complications, and the contraindications of this surgery should be given attention.


An exploring instrument called as a laparoscope is inserted unto the patient’s abdomen by making four to six small incisions. The laparoscope has a camera, which is attached to a monitor, allowing the surgeon to view and navigate through the patient’s abdomen. The abdomen is filled with gas to expand it therefore allowing good access to the operative site.

The stomach is resized into a small pouch, less than 10 ml, with the use of stapling instruments. The rest of the stomach’s portion (about 99%) is not removed, yet it is stapled and divided from the small pouch created.

The small intestine is divided by making a cut just beyond the ligament of Treitz. The remaining portion of the small intestine is then connected to the end of the small stomach pouch. This procedure makes food go directly to the small portion of the stomach and into the remaining part of the small intestine (the part where absorption is minimal).


Laparoscopic Gastric Bypass Surgery is the more preferred choice of some patients since it allows for a shorter hospital stay and faster recovery phase. In addition, it causes less pain. It also prevents the risk for complications such as hernia and infection to rise because the incisions are only minimal.


On the other hand, Laparoscopic Gastric Bypass Surgery also presents certain risks to one’s health since absorption of nutrients is largely hampered due to the small stomach and the bypass created.

Nutritional deficiency conditions like iron deficiency anemia
Metabolic bone diseases, fractures
Chronic anemia
Dumping syndrome

Fortunately, all nutritional deficiencies may be handled through proper diet and vitamin supplementation.


Just like in any other operation, Laparoscopic Gastric Bypass Surgery may also lead to complications such as the following:

Allergic reactions to medications
Deep Vein Thrombosis
Respiratory problems
Heart attack or even stroke post-surgery


There are certain exceptions to the use of Laparoscopic Gastric Bypass Surgery for obese patients. Individuals with the following conditions are not suitable candidates for the said operation:

Extremely limited mobility
Extremes of age
Endocrine disorders such as Prader Willi Syndrome and Cushing’s Disease
Psychological imbalance (e.g. alcohol or drug abuse, inability to cope with life changes, refusal to be subjected to a psychologist or psychiatrist’s assessment)
History of pulmonary diseases requiring oxygen therapy and pulmonary embolus
Psychiatric disorders left untreated

For individuals with complex medical conditions, the decision of whether they may be allowed to undergo the operation lies on the surgeon under a case-to-case basis.

Laparoscopic Gastric Bypass Surgery is a major operation. Even though it is now much safer, all matters should first be considered before the decision to have this type of operation.
