BackgroundSleeve gastrectomy is a stapler dependent bariatric procedure. A stapleless sleeve gastrectomy can be necessary for certain circumstances.AimsHere, we aimed to show whether laparoscopic stapleless sleeve gastrectomy with natural orifice specimen extraction (NOSE) can be an alternative procedure to stapled sleeve gastrectomy.Patients And MethodsIn the stapleless group (n = 6), no staplers were used and after vertical resection of the stomach by energy devices, the stomach remnant was closed by two rows of intracorporeal sutures. The resected specimen was removed through the mouth using an endoscopic snare. In the stapler group (n = 7), sleeve gastrectomy was carried out with linear stapler under the guidance of 36 Fr bougie. The specimens were extracted from the left upper quadrant trocar site.ResultsA total of 13 patients were compared (stapleless = 6 and stapled group = 7). All the sleeve gastrectomies were completed laparoscopically. The operative time was longer at 200 minutes (range 120-300) versus 120 minutes, (range 90-200) p = 0.07) and the amount of bleeding was higher at 100 ml (range 50-200) versus 30 ml (range 10-50) (p = 0.004) in the stapleless group. Leakage and gastrointestinal bleeding were seen in the stapleless group but no complications were found in the stapler group. No statistically significant difference was found between the metabolic outcomes of the two groups after the operation (p > 0.05). Decrease in BMI at similar rates was observed in 5 postoperative year (stapleless group: 35 kg/m2 (range 31-39) versus stapled group: 36.5 kg/m2 (range 31-39), p > 0.05).ConclusionLaparoscopic stapleless sleeve gastrectomy with natural orifice specimen extraction has longer procedure time, more blood loss and complications.
