A Multidisciplinary Approach
Options of Procedures
Among the host of procedures that we offer, our team will choose a specific procedure after evaluation of your basic body composition. The procedures that we offer include:
This is a laparoscopic procedure in which will be done through 4 to 5 small holes in your abdomen. Part of your stomach is removed resulting in a tube. This is a non-reversible procedure. This tube has capacity to withhold up to 150 ml. Sleeve procedure is reserved for lower BMI patients or as a first procedure in a series of procedures for higher BMI groups. After surgery there is early filling of stomach and removal of hormones which increase hunger, thereby resulting in a lesser appetite and early feeling of “being full”.
In this procedure, through 4 to 5 small holes your stomach is converted into a pouch. This pouch has a capacity of almost 200 ml and is connected to a part of small intestine. This causes less amount of food to be eaten and early feeling of being full. This procedure also causes a significant amount of food to be unavailable for digestion, thereby causing weight loss. This is an entirely reversible procedure, but diarrhea can occur as a side effect as well. This procedure is reserved for high BMI.
The procedures of sleeve with proximal jejunal bypass and duodenojejunal bypass are further modifications of sleeve gastrectomy. In cases where BMI is high, but patient is not a candidate for gastric bypass or having poor pancreatic function.
What to Expect after Bariatric Surgery
Time to RecoveryBased on the procedure that you are undergoing, you will be admitted after basic workup one day prior to surgery. After the procedure you will be asked to move about and start sips of water as soon as you are awake. Next day you will be kept on water and a dye test may be done to check the condition of your stomach and intestines. Subsequently, you will be discharged after passage of stool / flatus .You can join work within one week of surgery. As the procedures offered are done laparoscopically, you will experience minimum pain and discomfort.
