Sleeve operation

Longitudinal i.e. “sleeve” stomach resection is an operation in the process of which the major part of stomach is removed in the form of a sleeve. What remains is a tubular stomach of diminished dimensions accommodating much less food and rapidly generating the feeling of being fed to capacity. The given operation belongs among restrictive operations – meaning that neither the track of movement of food nor the digestion (absorption) process are changed, it is only the capacity of the so-called food reservoir that is limited.
Originally, the given technique was contemplated as the first stage prior to a larger operation of by-passing the stomach (the follow-up second stage to be performed in about half a year), however by now it has developed into an independent operation rapidly gaining ground, because the operation brings about the necessary loss of body weight and the operation itself is less prone to complications setting in, as compared to the combined malabsorptive – restrictive operations.
Operation is performed laparoscopically – there will be made four 0.5 – 1 cm long incisions in the skin and one 2.5 – 3 cm long incision in the skin (for stomach resectate extraction). Operation takes 30 min – 1.5 hours.

Bypass-operation is a combined (malabsorptive + restrictive) surgical method, in the process of which, out of the upper part of stomach, a small stomach stump is formed, to which the small intestine is connected. When eating, the stomach stump rapidly fills with food. The upper part of the stomach sends to brain the signal about arrival of satiety. Satiety arrives rapidly and stays for long, although you have eaten but little. By way of small intestine – small intestine’ connection – the food later gets into contact with digestive fluids (malabsorptive component) and depending on BMI (Quetelet index), the length of its “path” will be varied in the process of operation. Operation will take from 1,5 to 2,5 hours. Operation is performed laparoscopically, however there is a possibility that in the process of operation a need for laparotomy arises, i.e. the operation becoming open.
