Abstract
Morbid obesity is now an important problem all over the world due to its multiple co-morbidities and its marked harmful effect on the lifestyle of the patient.
Surgical treatment for obesity has proved that it is the best and most effective, durable means of preventing the life-threatening complications and serious problems associated with morbid obesity. It is indicated by the ineffectiveness of non-surgical treatment methods and the high risk resulting from untreated obesity. Safe, effective surgical treatment methods increase life expectancy and quality of life for patients with extreme excess weight. Operations for morbid obesity have been developed over the last 40 years, based on malabsorption or gastric restriction, or a combination of both.
Bariatric surgical techniques share two fundamental designs: intestinal malabsorption and gastric restriction. Malabsorptive operations shorten the functional length of the intestinal surface for nutrient absorption, while restrictive procedures decrease food intake by creating a small neogastric pouch. Weight loss caused by malabsorption is often accompanied by excessive protein calorie malnutrition and macro- and micronutrient deficiencies.
Laparoscopic sleeve gastrectomy is a restrictive surgical technique that involves resection of a significant portion of the stomach by means of stapling the greater curvature. This procedure is rapidly gaining popularity and acceptance as a primary bariatric procedure with good results on weight loss.
Laparoscopic greater curvature plication is similar to laparoscopic sleeve gastrectomy but without the need for gastric resection. The stomach is reduced by dissecting the greater omentum and short gastric vessels, as in vertical sleeve gastrectomy, then the greater curvature is invaginated using multiple rows of nonabsorbable suture over bougie to ensure a patent lumen.
In conclusion, laparoscopic sleeve gastrectomy and laparoscopic gastric plication are considered safe and effective one-stage restrictive procedures to achieve weight loss in the morbidly obese patients.
