**4.6 Treatment of duodenal obstruction**

Superior mesenteric artery syndrome is a rare condition that results from intermittent functional obstruction of the third part of the duodenum. The diagnostic criteria are clinical, radiological and endoscopic. The classic approach has been open surgery [123]. There are case reports of robotic Roux-en-Y duodenojejunostomy as a surgical option for the treatment of this condition [106, 124].

Robotic repair of congenital duodenal atresia may help overcome the obstacles presented by the use of traditional rigid laparoscopic instruments, due to the difficulty in constructing a precise duodenal anastomosis, with robotic surgery the procedure is relatively straightforward [107]. About gastroduodenal obstruction due to trichobezoar in children and laparoscopy, we found several reports. We operated with RAS on a 12-year-old girl weighing 23 kg with pica and psychological disorder, with success and without postoperative morbidity [14].
