To compare radical surgery with a minimal approach for peptic ulcer bleeding in relation to survival.
A Swedish nationwide population-based cohort study from 1987-2008 compared survival after minimal surgery and definitive surgery. The cohort was also stratified into calendar year before and after the year 2000 for subgroup analyses. Data were collected from the Swedish Patient Register. The two surgical groups were matched based on the propensity score to mimic a randomized trial design. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox regression models adjusted for potential confounders.
4,163 patients were included. There were no differences in survival in patients who underwent definitive surgical procedures compared to those who underwent minimal surgery for a bleeding peptic ulcer during the full study period. Using minimal surgery group as the reference, the HRs for death in the definitive surgery group within 30 days, 90 days, 1 year, and 5 years were 0.87 (95% CI 0.72-1.05), 0.93 (0.80-1.09), 1.00 (95% CI 0.87-1.14), and 1.05 (95% CI 0.95-1.16), respectively. The corresponding HRs during the calendar period after the year 2000 were 1.05 (95% CI 0.65-1.69), 1.18 (95% CI 0.81-1.73), 1.17 (0.84-1.62), and 1.27 (95% CI 0.99-1.63), respectively.
This study found no worse overall survival after minimal surgery compared to more extensive surgery for refractory peptic ulcer bleeding, and indicated better long-term survival in the minimal surgery group during the more recent study period. A minimal approach is probably sufficient in most cases.
比较根治性手术与微创方法治疗消化性溃疡出血的生存率。
一项基于瑞典全国人口的队列研究,时间跨度为1987年至2008年,比较了微创手术和根治性手术后的生存率。该队列还按2000年前后的日历年分层进行亚组分析。数据从瑞典患者登记处收集。根据倾向得分对两个手术组进行匹配,以模拟随机试验设计。使用针对潜在混杂因素进行调整的Cox回归模型估计风险比(HR)和95%置信区间(CI)。
纳入4163例患者。在整个研究期间,与接受微创治疗出血性消化性溃疡的患者相比,接受根治性手术的患者生存率无差异。以微创治疗组为参照,根治性手术组在30天、90天、1年和5年时的死亡HR分别为0.87(95%CI 0.72 - 1.05)、0.93(0.80 - 1.09)、1.00(95%CI 0.87 - 1.14)和1.05(95%CI 0.95 - 1.16)。2000年后日历期的相应HR分别为1.05(95%CI 0.65 - 1.69)、1.18(95%CI 0.81 - 1.73)、1.17(0.84 - 1.62)和1.27(95%CI 0.99 - 1.63)。
本研究发现,与更广泛的手术治疗难治性消化性溃疡出血相比,微创手术后的总体生存率并不更低,且表明在最近的研究期间,微创治疗组的长期生存率更高。在大多数情况下,微创方法可能就足够了。
