SURGICAL-TREATMENT OF REFLUX STRICTURE OF THE ESOPHAGUS

The choice of surgery in patients with reflux-induced oesophageal stricture remains controversial. From 1976 to 1990, a total of 65 patients underwent fundoplication (36 patients), Collis gastroplasty plus fundoplication (ten), total duodenal diversion (four) and oesophageal resection (15). The postoperative mortality rate was 5 per cent (three patients): necrosis of the colon transplant in two patients and acute pancreatitis in one. The me&an follow-up was 25 (range 6-120) months. After conservative surgery, the median number of dilatations per patient per year significantly decreased (P < 0.001). Nine patients (25 per cent) complained of persistent or recurrent symptoms after standard fundoplication and six required reoperation. Clinical results were satisfactory in patients who underwent Collis fundoplication, total duodenal diversion and oesophageal resection. It is concluded that the causes of failed fundoplication are irreversible stricture or persistent gastro-oesophageal reflux; the latter may be caused by inefficacy or deterioration of the partial fundoplication wrap. A subtle degree of oesophageal shortening is probably underestimated in such patients and this may explain the better results obtained with the Collis fundoplication. Total duodenal &version is a good therapeutic option in patients who have undergone previous oesophagogastric surgery. Oesophageal resection should be reserved for patients with tight strictures unresponsive to dilatation or those with scleroderma, multiple previous operations or severe dysplasia in Barrett's oesophagus.
