1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundPharyngoesophageal dysphagia sometimes develops after esophagectomy. However, severe dysphagia after esophagectomy due to cricopharyngeus muscle dysfunction is a rare complication. There are no recommended clinical treatments for cricopharyngeus muscle dysfunction after esophagectomy. We report a case of myotomy for cricopharyngeus muscle dysfunction after esophagectomy. CASE PRESENTATION: A 75-year-old man with mild dysphagia diagnosed with advanced esophageal cancer by esophagogastroduodenoscopy at a clinic was admitted to our hospital. He had occasional mild dysphagia when he swallowed solid foods. After chemotherapy, the patient underwent minimally invasive esophagectomy with regional lymph node dissection and was reconstructed with a gastric conduit and cervical anastomosis by the retrosternal route. Aspiration pneumonia developed after esophagectomy without paralysis of the vocal cords. In esophagoscopy, there was no stricture around the anastomosis. However, severe pharyngoesophageal dysphagia with cricopharyngeus muscle dysfunction was revealed by videofluoroscopic examination. Bilateral cricopharyngeal myotomy was performed because balloon dilations had failed. The histological findings revealed atrophy and fibrosis of the cricopharyngeus muscle fibers. Pharyngoesophageal dysphagia improved immediately after myotomy. The patient swallowed solid food easily without dysphagia 12 months after myotomy.

conclusionDysphagia after esophagectomy was worsened by cricopharyngeus muscle dysfunction. Cricopharyngeus myotomy may lead to long improvement of pharyngo-oesophageal dysphagia after esophagetomy.
