Long small bowel stricture: repeat resection or strictureplasty

What is known

• Conventional heineke-mikulicz strictureplasty is used for strictures up to ~10 cm; intermediate (10–25 cm) uses finney and longer strictures the michelassi side-to-side isoperistaltic enteroenterostomy. ¹
• A guideline recommends strictureplasty as an alternative to resection for strictures <10 cm and where gut-length preservation is needed, with non-standard techniques for longer strictures. ¹
• Strictureplasty conserves bowel and minimizes short-bowel syndrome risk, and is favored in patients with prior resections or multiple stenoses. ^2,3
• A comparative study reported significantly longer recurrence-free survival after resection than after strictureplasty. ¹

What is unknown / caveats

• Resection yields longer recurrence-free survival, whereas strictureplasty preserves length and lowers short-bowel risk
• No retrieved head-to-head trial isolating repeat resection vs non-standard strictureplasty specifically in the multiple-prior-resection subgroup
• The >10 cm and multiple-resection scenarios come from narrative-review/guideline synthesis and meta-analysis background, not a dedicated comparative cohort
• The retrieved evidence does not directly quantify recurrence or complication rates for non-standard strictureplasty vs repeat resection in this exact high-risk subgroup.
