Single film examinations (iodine and/or barium) were reviewed in 28 patients who had undergone surgery on the cricopharyngeal muscle due to Zenker diverticula (24 patients), cricopharyngeal muscle incoordination (3 patients) and pharyngoesophageal web (one patient). All patients had had a myotomy which included the cricopharyngeal muscle and up to 3 cm of the cervical esophagus. Lateral and anterior deviation of the pharynx and cervical esophagus occurred regularly. A pharyngocutaneous fistula developed in 2 patients which healed within 3 weeks. In 5 patients there was a posterior leak of contrast medium during the first postoperative week which healed within 2 weeks. Six of these seven patients with a fistula or a leak had had either a diverticulum removed or sustained an accidental mucosal perforation. No patient had recurrence of diverticula, although, 9 patients developed a cricopharyngeal muscle impression. Iodine and barium examinations are important for monitoring early and late postoperative changes after cricopharyngeus myotomy.
对28例因Zenker憩室（24例）、环咽肌不协调（3例）和咽食管蹼（1例）而接受环咽肌手术的患者进行了单张胶片检查（碘剂和/或钡剂）。所有患者均进行了包括环咽肌和长达3 cm颈段食管的肌切开术。咽和颈段食管出现了规律性的侧向和前向移位。2例患者发生咽皮肤瘘，在3周内愈合。5例患者在术后第一周出现造影剂后漏，在2周内愈合。这7例有瘘或漏的患者中，有6例切除了憩室或意外发生了黏膜穿孔。尽管有9例患者出现了环咽肌压迹，但没有患者出现憩室复发。碘剂和钡剂检查对于监测环咽肌肌切开术后的早期和晚期变化很重要。
