“…There are no comparative studies available evaluating the clinical effect of covered and uncovered stents in malignant gastroduodenal obstruction. Recently, we reported that there was no advantage of covered stents over uncovered stents in the palliative treatment of malignant colorectal obstruction [17]. The purpose of this present study was therefore to compare the technical feasibility and clinical outcomes in a group with covered or uncovered SEMS insertion for malignant gastroduodenal obstruction.…”

Background. The placement of self-expandable metallic stents (SEMS) is known to be effective palliative treatment of malignant gastroduodenal obstruction. There are two types of SEMS Á covered and uncovered Á each with its own advantages and disadvantages. This study was conducted to compare between the clinical outcomes of covered and uncovered stents in patients with malignant gastroduodenal obstruction. Patients and methods. The study was conducted prospectively from January 1998 to June 2007 and 154 patients were included. All had symptomatic gastroduodenal obstruction and were not candidates for curative operation. Seventy patients received covered SEMS, while the other 84 received uncovered SEMS. We compared technical and clinical success rates, tumour ingrowth rate, stent migration rate, stent patency time and patient survival in both SEMS groups. Results. The technical and clinical success rates of the covered and uncovered stent groups did not differ. Stent migration was more frequent in the covered stent group than in the uncovered group (17.1% versus 0%; p00.0001). Tumour ingrowth was more frequent in the uncovered stent group than in the covered group (16.6% versus 2.9%; p00.0066). Stent re-intervention rate, stent patency time and patient survival did not differ between groups. Conclusion. Covered and uncovered stent insertions are technically feasible and effective palliative treatment of malignant gastroduodenal obstruction. Covered stents can reduce the risk of tumour ingrowth, whereas uncovered stents are effective in preventing stent migration. However, covered stents did not differ from uncovered stents in regard to other clinical outcomes.

“…There were reports using laser therapy to ablate this tumour ingrowth [22]; usually multiple sessions are required. More recently, the use of an additional covered stent is preferred by endoscopists [10,21], as was illustrated in the present case.…”

“…In particular, stent occlusion is seen in around 10-16% of patients and occurs more frequently in palliative settings [1,6,14,20]. It is a common cause of delayed recurrent obstruction following apparently successful initial SEMS implantation, especially with the use of uncovered stents [10,21]. Prospective studies and systemic reviews showed that the time for colonic reobstruction ranged from 48 hours to 480 days after stent placement [6,13,14,21].…”

Prospective studies and systemic reviews showed that the time for colonic reobstruction ranged from 48 hours to 480 days after stent placement [6,13,14,21]. This variation in stent patency duration may be due to difference in demographic factors, underlying malignancies, or types of stents used [6,14].…”

Endoscopic stenting for malignant large bowel obstruction is common nowadays. However, recurrent obstruction secondary to stent occlusion due to tumour ingrowth or overgrowth might occur. We reported a case of a 70-year-old man with large bowel obstruction initially treated with colonic stenting. It was complicated with recurrent intestinal obstruction, with colonoscopy showing stent blockage by tumour ingrowth over distal part of the stent. Successful endoscopic implantation of additional colonic stent over the old stent was achieved and intestinal obstruction was resolved afterwards.

Ежегодная заболеваемость в США составляет 145 000 новых случаев колорек-тального рака, на нее приходится ежегодно 55 000 смертей (9-10% смертности от всей онкопатоло-гии) [2][3][4][5][6]. По данным канцер-регистра Республи-ки Беларусь, за последних десять лет заболеваемость колоректальным раком увеличилась в 1,5 раза (с 363 в 2001 г. до 528 в 2010 г.)…”
