Current status of minimally invasive surgery for thoracic esophageal diverticula: systematic review and meta-analysis.
Review in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
introductionThoracic esophageal diverticula, including epiphrenic and parabronchial types, are rare clinical entities representing about 30% of all esophageal diverticula. Thoracic diverticula of the pulsion type have traditionally been associated with motility disorders and treated by stapled diverticulectomy with or without myotomy/fundoplication in patients experiencing disabling symptoms of dysphagia, regurgitation or pulmonary aspiration. Purpose of this study was to review the existing literature and estimate outcomes of minimally invasive surgery.
methodsSystematic review and meta-analysis. PubMed, MEDLINE, Scopus, Web of Science, Cochrane Central Library, and ClinicalTrials.gov were queried. The search was last updated on April 20, 2026. Outcomes were staple-line leak, overall complications, in-hospital mortality, and symptoms improvement.
resultsTwenty-one observational studies including 390 patients were analyzed. The age of the patients ranged from 23 to 83 years. Dysphagia (86%), regurgitation (73.4%), and respiratory symptoms (31.2%) were common indications for surgery. The size of the diverticula ranged from 2 to 11 cm. Preoperative use of standard or high-resolution esophageal manometry was reported in 18 studies. Achalasia (49.2%) was the most commonly associated motility disorder. Laparoscopic (61.9%), thoracoscopic (30.6%), or combined (6.7%) minimally invasive approaches were described. Adjunctive procedures were esophagomyotomy (87%) and Dor (34.6%) or Toupet (17.7%) fundoplication. The estimated pooled prevalence of staple-line leak was 9.8% (95% CrI 7.1-13.4%; I
conclusionsCurrent evidence reporting outcome for minimally invasive midesophageal and epiphrenic diverticulectomy is limited by study design and treatment heterogeneity. Future well-designed multicenter studies are required to assess the effect of surgical approach and esophageal myotomy on short-term morbidity, symptomatic outcomes, and recurrence rate.
