Introduction

Obesity is complex disease, its epidemic is increasing not only

in developed countries but also in developing countries like

India. Obesity leads to many diseases like T2D, hypertension,

sleep apnea and fatty liver disease.

Metabolic Cardiovascular Disease 9: 21-32.

Introduction

In 2013, 13% people were obese world wide. India is the

third most obese country with figures as high as 30 million.

In India problem is associated with under nutrition and the

significant proportion of overweight and obese people now

coexist. (Popkin, 2002).

Hypoalbuminemia in MGB

The high incidence of hypoalbuminemia was noticed in longer bypass

more than 230 cm.

In all the cases in which length of bypass was 200 cm or less, the

incidence of hypalbuminemia was not seen.

Except in one patient who had 200 cm bypass and hypoalbuminemia

was 3.0 g/dl. This patient was suffering from diabetic nephropathy. To

control the falling albumin levels in this patient we had to pay special

attention on his nutrition part and it was seen once patient started having

protein rich diet his level improved.

Step 1 • Nutritional Supplementation• In patients with Albumin Level between 2.6-3.5 g/dl

Step 2 •Reversal of Bypass•In patients with persistant Albumin Levels below 2.5 g/dl with ankle oedema

Management ofHypoalbuminemia in MGB

Management ofHypoalbuminemia in MGB

1 case of hypoalbuminemia had to be reversed.

All other cases of mild hypoalbuminemia responded to good nutritional

supplementation in the form of high protein diet and did not require any

intervention.

Now in all our patients the length of bypass is 200 cm and no

hypoalbuminemia is found in these patients.

Management of Hypoalbuminemiain Distal RNY

Revision Surgery is difficult, long and cumbersome.

Reversal requires revision of two anastamosis.

Summary

Audit indicted that … Mortality rate was 2.14 % in cases with LSG and 0.625 % in RNY

and NIL in MGB.

Leaks were highest in LSG (1.42 %) followed by RNY (0.625 %) and NIL

in MGB.

Persistent vomiting was in LSG only.

Weight regain was 14 % in LSG and 8 % in RNY but Nil in MGB.

Hypoalbuminemia was minimal in LSG, 1.9% in Standard RNY, 14% in

Distal RNY and 13.1% in MGB.

Resolution of Comorbidities like Dyslipidemia, T2D, Hypertension,

Excess Weight Loss was maximum in MGB

Conclusions

• On the basis of audit we concluded that MGB which is a

combination of sleeve and bypass is technically more easy to

perform in minimum time period comparative to LSG and RNY.

• Above all mortality rate was zero in MGB.

• EWL and resolution of comorbidities was highly significant in

our audit which simply makes MGB the simplest and most

effective procedure.

Policy

On the basis of this audit we suggest MGB is the procedure of

choice in patients with morbid obesity, who are compliant in taking

their vitamins, calcium and iron supplements.

LSG maybe done in non-compliant patients and who are ready to

accept weight regain.

RNY and MGB both procedures act on the same principle of

restriction and malabsorption but MGB supersedes RNY in its

technique, efficacy, reversibility and revisibility.
