[Mechanical entero-enteral anastomosis in surgery of the upper digestive tract].

The authors analyse the results relating to the use of a technical variation of entero-enteroanastomosis preparation in the reconstruction of the continuity of upper digestive tract with a defunctionalised Roux en Y loop. This variation includes the use of a circular Proximate ILS mechanical stapler. The series examined, operated during the period June 1993 to November 1994, includes a total of 57 patients, of which 51 with gastric neoplasia. 43 cases underwent total gastrotectomy with R1-R2 lymphoadenectomy and 8 cases underwent gastroresection; a further 3 emergency operations were performed for benign pathologies responsible for upper digestive tract hemorrhage. Moreover, in the 3 remaining cases 2 cysto-jejunal derivations for pancreatic pseudocysts were also performed using the same method, together with 1 hepaticojejunostomy secondary to calculosis of the common hepatic duct. Attention is focused on the analysis and description of the operating technique in order to identify the basic key stages as accurately as possible. In conclusion, the authors indicate that, in view of the excellence of results and the simple and rapid technical execution of this entero-enteroanastomosis, the use of this method was amply justified and undoubtedly advantageous both for surgeons and patients.
