摘要: 目的 探讨以实验用新西兰白兔为平台建立巨大腹壁疝和腹腔高压动物模型的可行性。方法 手术切除实验兔腹壁肌肉全层建立直径约3 cm的腹壁缺损。围手术期诱导限水型便秘使实验兔腹腔压力增高。观察腹壁疝形成过程,使用超声测量疝囊体积。再次手术测量腹腔内压,解剖疝囊和腹壁观察疝环,使用生物补片修补腹壁缺损,并再次测量腹腔内压,对比疝修补术前后腹腔压力变化。结果 术后3~18 d开始出现腹壁切口旁可复性包块,疝囊最大直径为(8.73 ±1.00)cm,疝环直径为(2.58 ±0.52)cm,术后腹腔内压显著高于术前腹腔内压[(13.93 ±1.61) cmH2O(1 cmH2O=0.098 kPa) vs(4.66 ±1.34)cmH2O,P<0.01]。结论 该方法建立兔腹壁巨大疝和腹腔高压模型的方法简单可行,为巨大腹壁疝的临床研究提供了可靠的动物模型。

Abstract: Objective To explore the feasibility of establishing the animal model of giant ventral hernia and intra-abdominal hypertension in New Zealand rabbits. Methods The muscular tissue and peritoneum was resected and the defect with diameter about 3 cm was constructed. The intra-abdominal pressure was increased with induction of constipation due to lack of water during perioperative period. The hernia establishment was monitored with measurement of the volume of hernia sac by ultrasound. Reoperation was performed to measure the intra-abdominal pressure. The hernia sac was dissected to confirm the presence of the hernia ring. The hernia repair surgery with biological mesh was performed, and the intra-abdominal pressure was measured again for the comparison. Results The abdominal reducible bulge beside the incision was formed during 3 to 18 days after operation. The average maximum diameter of the bulge was (8.73 ±1.00)cm. The average diameter of the hernia defect was about (2.58 ±0.52)cm. The intra-abdominal pressure increased significantly after the repair surgery[(13.93 ±1.61)cmH2O (1 cmH2O=0.098 kPa)vs (4.66 ±1.34)cmH2O, P<0.01]. Conclusion It is simple and feasible to establish the animal model of giant ventral hernia and intra-abdominal hypertension in rabbits with the method explored above mentioned, which is a reliable animal model for the clinical study of giant ventral hernia.
