A hypothesis has been formulated that mandates the adjustment of antireflux surgery to either a total or a partial wrap depending on the motor function of the esophagus to avoid dysphagia and other obstructive complaints. This hypothesis has been tested in a randomized, clinical trial where 106 chronic gastroesophageal reflux patients were allocated to either a total Nissen-Rossetti (n = 53) or a Toupet partial posterior (n = 53) fundoplication, irrespective of their preoperative esophageal motor function. All patients were followed at least 3 years, during which time none had a relapse of moderate to severe reflux symptoms. Motor dysfunctions defined as peristaltic amplitude </= 30 mmHg in the distal third and failed primary peristalsis with or without > 20% simultaneous contractions were noted in 67 patients preoperatively, but these patients did not have a specific symptom profile (e.g., dominated by obstructive symptoms) nor did seven patients with "aperistaltic esophagus." The incidence of dysphagia decreased from 20% preoperatively to 8% (mild) at 3 years after the operation with no difference between the surgical procedures. We were unable to demonstrate a relation between preoperative manometric findings and postoperative symptoms when assessed in the total group or when subdivided by the type of fundoplication (r < 0.3). Flatulence occurred more frequently among those with a total fundic wrap (p < 0.01). When patients representing motor dysfunction (see above) were specifically analyzed, we again observed no difference in outcome between those having a total or a partial fundic wrap. In conclusion, the concept of tailoring antireflux surgery based on the preoperative motor function of the esophagus in patients with chronic gastroesophageal reflux disease was not supported by the results of this clinical trial.
有一种假说认为,应根据食管的运动功能将抗反流手术调整为全包裹或部分包裹,以避免吞咽困难和其他梗阻性症状。该假说已在一项随机临床试验中得到验证,106例慢性胃食管反流患者被随机分配接受全胃底折叠术(nissen - rossetti,n = 53)或Toupet部分胃底后折叠术(n = 53),无论其术前食管运动功能如何。所有患者均随访至少3年,在此期间,无一人出现中度至重度反流症状复发。术前67例患者存在运动功能障碍,定义为食管远端三分之一处蠕动幅度≤30 mmHg,原发性蠕动失败,伴或不伴>20%同步收缩,但这些患者没有特定的症状特征(如以梗阻性症状为主),7例“无蠕动食管”患者也没有。吞咽困难的发生率从术前的20%降至术后3年的8%(轻度),两种手术方式之间无差异。在对全组或按胃底折叠术类型细分时,我们无法证明术前测压结果与术后症状之间存在关联(r < 0.3)。全胃底包裹患者中腹胀更为常见(p < 0.01)。当对存在运动功能障碍的患者(见上文)进行具体分析时,我们再次观察到全胃底包裹或部分胃底包裹患者的结局无差异。总之,这项临床试验的结果不支持根据慢性胃食管反流病患者术前食管运动功能来调整抗反流手术的概念。
