Gastrointestinal anastomosis technique – Roux-en-Y esophagojejunostomy - general and visceral surgery

Open the distal esophagus by transverse transection of its anterior wall and secure it proximally with an Allis forceps; this will prevent the distal esophagus from retracting craniad into the mediastinum. Now transect the posterior wall of the esophagus. Preplace a purse string suture (monofilament, nonabsorbable, 2/0, continuous full-thickness over-and-over) and gently dilate the esophagus with a dressing forceps. Insert the anvil of a circular EEA stapler and secure it by tying the preplaced purse string suture.

In order to achieve a good functional result, the segment of the jejunum must be dissected sufficiently long. To this end, lift the transverse colon craniad, hold up and spread the jejunal mesentery and under transillumination with the surgical light assess the arterial supply of the second jejunal loop. The intestine and mesentery of the efferent limb should be transected such that the transected end of the limb will easily reach the esophagus.

Incise the mesenteric peritoneum and gently divide the mesenteric arcades such that the arterial supply at the site of the bowel transection remains adequate. Now transect the intestine with the electrocautery.
