Input: We identified three randomised controlled trials with 84 participants. Forty-one participants underwent surgical palliation and 43 participants underwent duodenal stent placement. There may have been little or no difference in the technical success of the procedure (RR 0.98, 95% CI 0.88 to 1.09; low-quality evidence), or whether the time to resumption of oral intake was quicker for participants who had undergone duodenal stent placement (MD -3.07 days, 95% CI -4.76 to -1.39; low-quality evidence). Due to very low-quality evidence, we were uncertain whether surgical palliation improved all-cause mortality and median survival postintervention. The time to recurrence of obstructive symptoms may have increased slightly following duodenal stenting (RR 5.08, 95% CI 0.96 to 26.74; moderate-quality evidence). Due to very low-quality evidence, we were uncertain whether surgical palliation improved serious and minor adverse events. The heterogeneity for adverse events was moderately high (serious adverse events: Chi² = 1.71; minor adverse events: Chi² = 3.08), reflecting the differences in definitions used and therefore, may have impacted the outcomes. The need for reintervention may have increased following duodenal stenting (RR 4.71, 95% CI 1.36 to 16.30; very low-quality evidence). The length of hospital stay may have been shorter (by approximately 4 to 10 days) following stenting (MD -6.70 days, 95% CI -9.41 to -3.98; moderate-quality evidence). The use of duodenal stent placement in malignant gastric outlet obstruction has the benefits of a quicker resumption of oral intake and a reduced inpatient hospital stay; however, this is balanced by an increase in the recurrence of symptoms and the need for further intervention. It is impossible to draw further conclusions on these and the other measured outcomes, primarily due to the low number of eligible studies and small number of participants which resulted in low-quality evidence. It was not possible to analyse the impact on quality of life each intervention had for these participants.
Output:

Three studies with 84 participants compared a surgical operation to bypass the blockage with the placement of a duodenal stent to bridge the blockage. The evidence is current to May 2018. All studies found that people were able to eat and drink sooner following the placement of a duodenal stent and were subsequently discharged from hospital quicker. The return of symptoms was more likely after a stent and people required further treatment to again restore the ability to eat and drink. There was a higher number of immediate problems in the participants undergoing gastrojejunostomy, including wound and chest infections. In some of the participants who had a stent, subsequent blockage of the stent occurred that required a repeat procedure. The studies included only a small number of participants and all studies were used slightly different methods, making it difficult to be certain of the key results.
