Abstract
BackgroundThe endoscopic placement of a self‐expandable metal stent (SEMS), an alternative to surgical bypass for the palliation of malignant gastric outlet obstruction (GOO), is commonly performed using a forward‐viewing endoscope with a wide therapeutic channel; however, due to limited availability, most Indian centers use a side‐viewing duodenoscope. We studied the feasibility and outcome of SEMS placement using side‐ and forward‐viewing endoscopes.MethodData of patients undergoing SEMS placement using side‐ and forward‐viewing endoscopes with a therapeutic channel for the palliation of malignant GOO presenting during a 5‐year period were analyzed retrospectively. Follow‐up data were obtained from records and telephonic interviews, and technical and clinical success, complications, and survival were evaluated.ResultsOf 114 patients (age 56.5 ± 11.6 years, 59 [52%] female), 90 (79%) and 24 (21%) underwent SEMS placement using side‐ and forward‐viewing endoscopes, respectively. Technical (89, 98.9% vs. 24, 100%, P = ns) and clinical success (84, 93.3% vs. 23, 95.8%, P = ns) and complication rate (3, 3.3% vs. 0, P = ns) between side‐ and forward‐viewing endoscopes were comparable. However, SEMS could be placed in a shorter time using a forward‐ rather than side‐viewing endoscope (21 min [inter‐quartile range 19.5–35] vs. 34 min [25–45], P = < 0.001). SEMS could be deployed successfully with a forward‐viewing endoscope in two patients in whom an initial attempt using side‐viewing endoscope failed. Gastric outlet obstruction scoring system (GOOSS) improved following stent placement (median 0, range 0–2 vs. 2, 0–3, P = 0.0001). The survival of patients undergoing SEMS placement using side‐ and forward‐viewing endoscopes was comparable.ConclusionAlthough side‐ and forward‐viewing endoscopes are equally effective for antroduodenal SEMS placement, the procedure can be performed faster using the latter.
