Self-expanding metal stents are increasingly being used to palliate patients with obstructing gastrointestinal cancers in less than conventional circumstances. We report the unusual application of stenting in the case of a woman with dysphagia caused by recurrent gastric carcinoma after a total gastrectomy. Despite initial difficulties, the insertion of a self-expanding metal stent across the esophago-jejunal anastomosis provided excellent palliation and avoided further surgery. This case illustrates the benefits of persisting with combined palliative treatments in difficult situations.

of undigested food in August 1996. She had undergone a total gastrectomy in October 1995 for gastric adenocarcinoma. Gastroscopy performed urgently revealed a high-grade malignant stricture 33 cm from the incisors extending distally for 6 cm. The tumor was dilated gently with the endoscope and partially debulked by photoablation with the Nd/YAG laser. Despite a second session of laser therapy, the patient’s symptoms continued. At repeat endoscopy the endoscope could be easily passed into what appeared to be an afferent loop but could not be negotiated into the efferent loop of jejunum, the entrance of which had not been recognized at previous endoscopic examination because of obstructing tumor. A barium swallow revealed a tight malignant anastomotic stricture at the junction of the esophagus and efferent jejunal loop of Roux-en-Y (Fig. 1). Because of the anatomy and angulation of the stricture, further endoscopic laser therapy was judged to be relatively hazardous. The patient refused further surgery. After one failed attempt with a standard endoscopy we managed to intubate the entrance to the efferent jejunal loop with a smaller diameter endoscope (Pentax EG2901; Pentax (UK) Ltd., Langley, U.K.) and pass a guidewire well beyond the stricture into the jejunum, allowing the scope to follow safely. A 10 cm long, 18 mm expanded diameter Microvasive Ultraflex uncovered esophageal prosthesis (Boston Scientific Inc., Boston, Mass.) was then deployed across the stricture. Initial expansion was incomplete despite attempted dilatation of the stent with a 12 mm balloon. In view of reports and our experience of delayed stent expansion, we waited to see whether this stenting attempt was sufficient. Unfortunately the patient continued to complain of VOLUME 47, NO. 2, 1998

DISCUSSION dysphagia and vomiting. Repeat radiographs, a contrast swallow and a gastroscopy confirmed that the stent had failed to open fully because of tumor compression (Fig. 2). Attempts to pass the endoscope through the stent caused the mesh to fracture. In view of the failure of the primary stent a second stent with a higher radial force was placed across the Ultraflex stent. Under fluoroscopic guidance it was possible to intubate this with the small diameter endoscope with difficulty and place a guidewire deep into the jejunum. An Esophacoil prosthesis (Instent, Eden Prairie, Minn.), 15 cm long, 18 mm diameter was deployed straddling the original stent (Fig. 3). Although this stent did not expand immediately, a gastroscopy 4 days later revealed the stent was correctly placed and well open; some of the coils in the middle of the stent were splayed apart with some tumor protruding through. This was treated with Nd/YAG laser photoablation to good effect. The patient was discharged home able to swallow semi-solid food and otherwise asymptomatic. She survived a further 24 weeks with good swallowing but 1 week before her death developed jaundice for which she refused any further intervention. VOLUME 47, NO. 2, 1998
Self-expanding metal stents are conventionally used for palliation of malignant esophageal and biliary obstruction.1,2 New uses are still being found, for example, in the rectum and sigmoid,3,4 for gastric outlet obstruction5,6 and for duodenal compression caused by pancreatic carcinoma or metastases.7 This case illustrates several points relevant in luminal gastrointestinal tumor palliation. Our patient did not have a usual indication for a metal stent but still did well after some persistence and avoided surgery. There have been several reports of unconventional but successful uses of stents, and they should now be considered for palliation of patients with endoscopically accessible, obstructing, incurable tumors. Developments in stent technology are likely to increase the choice of prostheses and the range of indications. At present each of the four stent types generally available (the Ultraflex prosthesis, the Esophacoil, the Wallstent, and the Gianturco-Rosch Z stent) have achieved favorable results in medium-sized GASTROINTESTINAL ENDOSCOPY 193

locations helps when deciding if stenting a particular tumor is likely to be successful. Patients appreciate the rapid symptomatic improvement a stent can bring. In this patient, although the series of endoscopies, laser treatment and stenting attempts did take considerably longer than is usual, much of her treatment was performed on an outpatient basis. She was grateful to avoid surgery and pleased with the eventual symptom relief. REFERENCES

series.8-11 All have important differences that can be exploited in various clinical situations; in most cases, use of any of the stents will be successful. Our case shows that when treatment with the first chosen stent is unsuccessful, it is worth trying an alternative prosthesis. Our case also illustrates the importance of appreciating the deranged anatomy of a malignant stricture when attempting to stent it. For all cases where stenting is less than straightforward we perform contrast studies; in this patient’s case we would have benefited from requesting the radiologic examination earlier. We often find that initial laser therapy helps in managing malignant obstruction, to reduce bulky exophytic parts of the tumor even if it is decided that stent placement is required. The use of laser therapy after stenting can be difficult as the stent metal can melt or, as in one report, ignite.12 However with low power and careful aiming we have found laser therapy useful to treat tumor ingrowth, overgrowth, or residual unstented tumor. Stents are likely to remain fairly expensive but probably save money if surgery is the alternative. Experience with different stent types in various
