摘要

BACKGROUND: There are few reports of overall strength of laparoscopic and open incisional hernia repair. METHODS: After anesthesia, a 2-inch circular defect was made in the abdominal wall of 28 female swine. Gore-Tex DualMesh Biomaterial (W. L. Gore & Associates, Flagstaff, AZ) was used for all repairs. Sixteen animals underwent open repair and 12 underwent laparoscopic repair. Burst strength was detected within 2 weeks and at 6 weeks by euthanizing the animals and insufflating the abdominal cavity with water while measuring the intraabdominal pressure until it could no longer be pressurized. RESULTS: Three events occurred after insufflation: rupture around patch (R), dissection from insufflation or pressure monitoring sites (D), or rectal prolapse (P). Failure after open early repair occurred at 289 (range 219-388) mmHg with 7-R, 1-P and late 289 (196-343) mmHg with 1-R, 6-P. Failure after laparoscopic early repair occurred at 259 (191-388) mmHg with 4-R, 1-P, 1-D and late 291 (140-330) mmHg with 2-R,1-P, 3-D. Late groups were less likely to rupture. CONCLUSION: Both hernia repairs are durable at early and late periods. Tissue ingrowth adds to repair strength. We could not show that one repair was stronger than the other. Nonetheless, laparoscopic repair tended to degrade by dissection, which was our highest pressure event.

Gore＆Associates，弗拉格斯塔夫，亚利桑那州）进行。十六只动物进行了开放式修复，十二只动物进行了腹腔镜修复。通过对动物实施安乐死并用水注入腹腔，同时测量腹腔内压力直至不再受压，在2周和6周内检测到爆发力。结果：吹气后发生了三个事件：贴片周围破裂（R），从吹气或压力监测部位解剖（D）或直肠脱垂（P）。开放式早期修复失败发生在7-R，1-P的289（219-388）mmHg和1-R，6-P的289（196-343）mmHg的晚期。腹腔镜早期修复失败发生在4-R，1-P，1-D的259（191-388）mmHg和2-R，1-P，3-D晚期的291（140-330）mmHg的患者。晚期组破裂的可能性较小。结论：两种疝气修补术在早期和晚期都是持久的。组织向内生长可增加修复强度。我们无法证明一项维修要强于另一项维修。尽管如此，腹腔镜修复往往由于解剖而退化，这是我们的最高压力事件。
