Standard Roux-en-Y gastrojejunostomy vs. "uncut" Roux-en-Y gastrojejunostomy: a matched cohort study

Roux-en-Y gastrojejunostomy is a common method of reconstruction after subtotal gastrectomy. Maintaining myoneural continuity has been proposed to decrease the incidence of Roux stasis syndrome, with an "uncut" Roux-en-Y reconstruction. The aim of our study was to compare the clinical results in patients who have undergone uncut Roux-en-Y gastrojejunostomy with those in patients who have undergone a standard Roux-en-Y gastrojejunostomy. Eleven patients underwent gastrectomy and uncut Roux-en-Y gastrojejunostomy and were compared with a cohort of 14 patients who underwent gastrectomy and standard Roux-en-Y gastrojejunostomy. Patients were contacted and charts were reviewed for Visick grade, early and late morbidity and mortality, and incidence of staple line dehiscence. Early postoperative morbidity was 18% in patients undergoing uncut Roux gastrojejunostomy and 28% in patients undergoing standard Roux reconstruction. There were no early postoperative deaths in either group. In the patients undergoing the uncut Roux procedure, no cases of staple line dehiscence were detected clinically (mean follow-up 9 months, range 1 to 48 months). Visick grade improved following the uncut Roux procedure, but changed little after standard Roux reconstruction. Uncut Roux-en-Y gastrojejunostomy can be performed safely with improvement in symptoms. The uncut Roux procedure may provide an alternative for reconstructive gastric surgery.
