Abstract
Purpose: Gastric outlet obstruction is a debilitating complication of upper gastrointestinal malignancy. We present our experience with insertion of self-expanding metal stents (SEMS).
Methods: Twenty-eight patients were referred, stenting being attempted in 23. Two patients had esophageal Wallstents inserted through a gastrostomy; 21 had an endoscopic approach with enteral Wallstents.
Results: One stent insertion failed, ten patients (45%) returned to a normal diet, ten patients (45%) managed semi-solid food and two patients (9%) had no significant improvement. No immediate complications were seen. One patient subsequently developed pancreatitis. Reintervention (4 stents, 1 jejunostomy, 1 gastrojejunostomy) was required in six of 22 patients (27%) for inadequate stent expansion (1), second stricture (2), stent migration (1), and tumor ingrowth (2). The mean survival was 95.4 days (SD 78.8 days, range 3–230 days). The mean follow-up time was 98.9 days (SD 86.7 days, range 3–309 days).
Conclusions: SEMS are effective in palliating malignant gastric outlet obstruction. A combined endoscopic/fluoroscopic approach allows the most complete assessment of the stricture and removes the need for gastrostomy insertion. Careful assessment of the gastrointestinal tract distal to the lesion is important.
