|Surgical removal of partial or full stomach is called gastrectomy. Gastrectomy is done to remove stomach wall perforation or to treat stomach cancer. There are four types of gastrectomy- partial gastrectomy, full gastrectomy,sleeve gastrectomy and oesophagogastrectomy. Partial gastrectomy means removal of lower half of the stomach portion. The upper part of the stomach is then connected to small intestine. In full gastrectomy there is entire removal of the stomach and oesophagus is directly attached to the small intestine. Sleeve gastrectomy is the removal of left side of the stomach. It removes the stomach volume upto 75%. Oesophagogastrectomy means removal of upper portion of the stomach and part of oesophagus. The remaining aprt is then pulled upward and sealed. The lower part of the stomach is then pull upward and attached to the end of the oseophagus.
There are certain risks involved in gastrectomy that includes nausea, vomiting, infection of the chest, weight loss and vitamin deficiency and can also cause osteoporosis and anemia. Gastrectomy is performed in two different ways- open surgery and laparoscopic surgery. Open surgery involves a single large excision. The surgeon pulls back the skin, muscle and tissues to get access to the stomach. In laparoscopic surgery small incision is made with the help of specialized tools. It is more advanced surgery and with less complications. Because of this it is preferred surgery than open surgery. After the surgery is performed the person has to adjust the eating habits like eating smaller amount of food throughout the day, avoiding high fiber food and eating food rich in calcium, iron and vitamin C and D.
