International expert consensus on the management of paraconduit herniation after esophagectomy: results of a two-round Delphi survey.
Article 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
aimsThe management of Paraconduit Herniation after Esophagectomy (PCH) is controversial. This survey aims to identify recommended strategies for prevention and patient handling (including indication, preoperative work-up, technical-surgical details and follow-up) using the Delphi methodology.
methodsWe conducted a 2-round, 32-question, web-based International Delphi survey focusing on non-revisional, elective PCH in asymptomatic patients among surgical upper GI experts. Responses were graded on a 5-point Likert scale and analyzed using descriptive statistics. Items from the questionnaire were defined as "recommended" or "discouraged" if positive or negative concordance among participants was > 75%.
resultsEighty-two surgeons with a median (IQR) experience of 17.5 (12-27) years from 19 countries across four continents (Europe, North America, Asia, Australia) participated in both Delphi rounds (response rate 43%). The annual median (IQR) individual and institutional caseload was 5 (5-5) and 5 (5-10) PCH surgeries, respectively. After Delphi round 2, strong expert consensus (> 75% agreement) was achieved for: (1) Preventive measures: avoiding opening the left pleura during index esophagectomy; (2) Indications for repair: prioritizing biologically younger (< 80 years) and tumor-free patients, complex multi-organ herniation, and radiographically enlarging PCH on surveillance, while explicitly discouraging repair for stable PCH or tumor recurrence; (3) Surgical approach: preferring laparoscopic or robotic-assisted laparoscopy with single-stitch suture hiatoplasty and gastropexy; and (4) Mesh use: utilizing biosynthetic absorbable mesh for high-risk selective cases (recurrent PCH, weak crura, large hiatal area) fixed with sutures, while explicitly discouraging the use of tacks. In contrast, many items from the questionnaire including surgical measures to prevent PCH and most technical details of mesh augmentation (material, shape, and placement) did not reach positive or negative concordance.
conclusionsThis International Delphi survey represents the first expert-led process to identify recommended strategies for the management of PCH. Our work may be useful in clinical practice to guide the diagnostic process, increase procedural consistency and standardization, and to foster collaborative research.
