腹腔镜联合胃镜微创治疗贲门失弛缓症的临床分析

腹腔镜联合胃镜微创治疗贲门失弛缓症的临床分析天津医科大学硕士学位论文中文摘要目的：国际上，腹腔镜贲门括约肌切开术是目前外科治疗贲门失弛缓症的首选方案。

但在我国，多数较重病人仍选择内科治疗，此种手术只在极少数医院开展。

本文研究腹腔镜联合胃镜行Heller肌切开术附加胃底折叠术微创治疗贲门失弛缓症的临床效果及其优势。

方法：选取天津市微创外科中心从2005年2月至2011年1月应用腹腔镜联合胃镜行Heller括约肌切开术附加Dor胃底折叠术治疗贲门失弛缓症33例患者为研究对象。

其中男18例，女15例，年龄24--一70岁，平均43岁。

病程18～105个月，平均42个月。

体重下降5--一25 kg，平均10 kg。

其中2例曾做球囊扩张治疗，2例曾注射肉毒碱治疗。

所有纳入病例均通过上消化道造影、食管测压、胃镜检查，用以明确诊断和排除食管占位性病变。

33例均经24小时pH值监测除外术前胃食管反流。

所选病例均在全麻下行腹腔镜Heller肌切开术附加Dor胃底180 度前折叠术，术中联合胃镜操作，监视肌切开范围，深度，并确认食管粘膜完全外露。

同时，术中胃镜及时发现粘膜穿孔，并在直视下行粘膜修补。

随访通过病例查阅获得病人基本信息，并通过电话或随访信与病人联系回访，以对其术后生活质量进行客观评价。

通过对手术前后主客观指标和随访观察情况进行对比分析，客观评价腹腔镜术中联合胃镜操作的微创治疗优势和手术效果，确立腹腔镜联合胃镜治疗该病的指征，形成规范的操作规程，指导临床工作。

结果：33例均顺利完成腹腔镜手术，未有中转开腹病例，无死亡病例。

手术的平均时间为90．26min(60～145min)，出血量平均45ml(50～150m1)。

术中1例(曾接受肉毒杆菌毒素注射治疗)由于粘连严重，食管环形肌、纵行肌融合，层次不清，术中造成贲门上方约lcrn处食管粘膜破裂，经术中胃镜证实后及时行腹腔镜下穿孔修补术。

术后胃镜再次检查，确认修补牢靠。

术后无严重并发症，无食管瘘发生。

患者术后平均住院时间5．2天(4--一9天)。

术后进行随访，33例病人均表示吞咽困难较术前明显改善，复查胃镜显示33例患者贲门部镜身通过无阻力，食管粘膜炎症改变明显好转；上消化道造影和术前相比显示食道下段扩张明显减轻，下端造影剂排空良好。

食道测压显示33例LES静息压、残留压明显下降，松弛率升高，与手术前相比均有统计学差异(P<O．05)，和正常参考值比较无统计学差异(P>0．05)，表明各项指标已经恢复到正常水平。

术后24小时PH检测显示未有胃食管反流。

天津医科人学硕十学位论文结论：(1)腹腔镜Heller肌切开术附加Dor胃底折叠术是目前外科治疗该病的首选方案。

腹腔镜治疗贲门失弛缓症具有手术创伤小、恢复快、疗效可靠的特点，术中联合胃镜操作不仅能够确认肌切开是否完全，掌握肌切开的部位、深度和长度，而且可提高手术安全性，减少并发症的发生。

(2)食管下段括约肌的切开应该完全打开食管肌层，直至食管粘膜显露为标准，长度控制在4．6cm，否则会影响食管的正常蠕动功能，贲门下方胃底的切开应该在1．5cm左右，不宜超过2cm，以保存天然的抗返流屏障。

(3)病程长，食管扩张严重S的形病人术后症状改善较慢，部分不理想。

(4)内镜扩张或注射治疗会使食管肌层、粘膜融合，解剖层次不清。

因此，既往接受过内镜治疗的患者给日后手术操作带来困难。
