Achalasia manifests as failure of relaxation of the lower esophageal sphincter resulting in dysphagia. Although there are several medical and endoscopic treatment options, laparoscopic Heller myotomy has excellent short- and long-term outcomes. This article describes in detail our surgical approach to this operation. Key steps include extensive esophageal mobilization, division of the short gastric vessels, mobilization of the anterior vagus nerve, an extended gastric myotomy (3 cm as opposed to the conventional 1-2 cm gastric myotomy), a minimum 6 cm esophageal myotomy through circular and longitudinal muscle layers, and a Toupet partial fundoplication. We routinely use intraoperative endoscopy both to check for inadvertent full-thickness injury and to assess completeness of the myotomy and the geometry of the anti-reflux wrap.
贲门失弛缓症表现为食管下括约肌松弛功能障碍,导致吞咽困难。尽管有多种药物和内镜治疗选择,但腹腔镜Heller肌切开术具有出色的短期和长期疗效。本文详细描述了我们对此手术的手术方法。关键步骤包括广泛游离食管、切断胃短血管、游离前迷走神经、延长胃肌切开术(传统胃肌切开术为1-2cm,此处为3cm)、通过环形和纵行肌层进行至少6cm的食管肌切开术以及Toupet部分胃底折叠术。我们常规在术中使用内镜检查,以检查是否存在意外的全层损伤,并评估肌切开术的完整性和抗反流包绕的形态。
