Summary Among 173 patients undergoing reconstructive gastric operations, including 115 patients who received Roux-en-Y gastrojejunostomy, 25 with jejunal interpositions, 11 with conversion of Billroth II to Billroth I, 8 with closure of gastroenterostomy, 5 with pyloric reconstruction and 9 with other operations, only 2 immediate postoperative mortalities occurred. A perfect or good result was obtained in 108 of 156 patients (69 per cent) at long term follow-up, while a fair result was achieved in 35 patients (22 per cent) and a poor result in 13 patients (9 per cent). We concluded that reconstructive gastric operations were safe and had clearly improved 7 of 10 patients in this series.
