Handsewn Kono-S anastomosis is safe and associated with a reduction in postoperative recurrence (POR) in Crohn disease (CD). This study aimed to investigate the advantages of stapled Kono-S anastomosis in patients with CD who underwent intestinal anastomosis.
Patients with CD who underwent intestinal anastomosis were reviewed via a prospectively maintained database. Patients who underwent conventional stapled side-to-side anastomosis were classified into the conventional group, and those who underwent stapled Kono-S anastomosis were classified into the Kono-S group. The primary endpoint was modified endoscopic recurrence (mER; ≥i2b). Other endpoints were endoscopic recurrence (ER; ≥i2); severe ER (i3 and i4); intra- and postoperative outcomes, including morbidity and hospital stay; and cross-sectional parameters. Multivariate logistic regression analysis was performed to assess the independent risk factors for mER.
Between 2020 and 2023, 199 patients (63 in the Kono-S group) were included in this study. After matching the 63 patients in each group, the overall rates of mER, ER, and severe ER were 19.0%, 24.6%, and 8.7%, respectively. The mER, ER, and severe ER rates were lower in the Kono-S group than in the conventional group (12.7% vs 25.4% [P =.07], 20.6% vs 28.6% [P =.30], and 6.3% vs 11.1% [P =.34], respectively). Multivariate analysis indicated that stapled Kono-S anastomosis (odds ratio [OR], 0.35; 95% CI, 0.12-0.98; P =.047) was an independent protective factor for mER, whereas male gender (OR, 7.75; 95% CI, 1.50-40.00; P =.01) and BMI of <18.5 kg/m (OR, 3.27; 95% CI, 1.11-9.67; P =.03) were independent risk factors for mER.
Stapled Kono-S anastomosis is safe for patients with CD. However, stapled Kono-S anastomosis may not be a protective factor against POR compared with conventional stapled side-to-side anastomosis.
手工缝合的小野 - S 吻合术是安全的，且与克罗恩病（CD）术后复发率降低相关。本研究旨在探讨吻合器行小野 - S 吻合术在接受肠道吻合术的 CD 患者中的优势。
通过前瞻性维护的数据库对接受肠道吻合术的 CD 患者进行回顾性分析。接受传统吻合器侧侧吻合术的患者被分为传统组，接受吻合器小野 - S 吻合术的患者被分为小野 - S 组。主要终点是改良内镜复发（mER；≥i2b）。其他终点包括内镜复发（ER；≥i2）、严重内镜复发（i3 和 i4）、术中和术后结局，包括发病率和住院时间，以及横断面参数。进行多因素逻辑回归分析以评估 mER 的独立危险因素。
2020 年至 2023 年期间，本研究纳入了 199 例患者（小野 - S 组 63 例）。在每组匹配 63 例患者后，mER、ER 和严重 ER 的总体发生率分别为 19.0%、24.6%和 8.7%。小野 - S 组的 mER、ER 和严重 ER 发生率低于传统组（分别为 12.7%对 25.4%[P = 0.07]、20.6%对 28.6%[P = 0.30]、6.3%对 11.1%[P = 0.34]）。多因素分析表明，吻合器小野 - S 吻合术（比值比[OR]，0.35；95%置信区间，0.12 - 0.98；P = 0.047）是 mER 的独立保护因素，而男性性别（OR，7.75；95%置信区间，1.50 - 40.00；P = 0.01）和体重指数<18.5 kg/m²（OR，3.27；95%置信区间, 1.11 - 9.67；P = 0.03）是 mER 的独立危险因素。
吻合器小野 - S 吻合术对 CD 患者是安全的。然而，与传统吻合器侧侧吻合术相比，吻合器小野 - S 吻合术可能不是预防术后复发的保护因素。
