DEFINITION OF MINI GASTRIC BY PASS

OMEGA LOOP BY PASS

Mini Bypass

  • Definition
  • The Surgical operation of Mini By not Gastric (MGB or by-pass gastrojéjunale with handle in Omega according to Billroth II) is led by laparoscopy.

    It is technically easier compared to classical by-pass LRYGB or known as by-pass in Y according to Russet-red because it removes a digestive joining..

The possible backward flow of bile towards the stomach imposes the creation of a gastric tank longer than in the classical bypass.
The intervention carried out under hard coelioscopy between 45min and 1:30.
The duration of stay is 24heures at 48 hours.
The reversibility in classical by-pass is possible: it is carried out by laparoscopy.
The post-operative rate of complications is lower than 4% (dents, bleeding)
  • mini gastric bypass

Advantages

 

ADVANTAGES OF MINI GASTRIC BY PASS

  • Short , Simple, Effective
  • Simple technique and rapid 40 min – 1, h30 min

    Loss of excess of weight comparable with the classical by-pass in Y with 2 anastomoses (LRYGB)

    Effectiveness controls diabetes

DISADVANTAGES AND COMPLICATIONS OF THE MINI BY-PASS

  • Disadvantages
  • biliary backward flow with invalidating gastritis or œsophagite alkaline
    conversion into classical by-pass
    fistula
    haemorrhage
    No complication related to the second anastomosis (internal dents, torsions, hernia)

RESULTS OF MINI GASTRIC BY PASS

LMGBP : Laparoscopic Mini Gastric By Pass

In short, compared to the by-pass in Y, the mini gastric by-pass or by-pass in Omega seems to be a procedure

  • Simpler and surer with average duration of stay shorter than the by-pass in Y
  • As effective as the by-pass in Y: similar results on weight loss, resolution of the metabolic syndrome and improvement of quality of life
  • Contrary to the classical bypass where there does not exist, the backward flow of bile can, in rare cases, symptomatic being. The backward flow of bile (burns, régurgitations bitter can justify a late conversion into classical by-pass (2%).
  • Long term results
  • The long-term results of the gastric mini-bypass must still be the object of a more complete evaluation but seem to be encouraging and superposable with those of the classical bypass.

    This technique also imposes to the patient the catch additional vitaminized, calcium, iron and zinc.
