The transhiatal tunnel valvuloplasty technique following laparoscopic proximal gastrectomy: the single-center experience in a retrospective cohort.

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
backgroundThe debate over the optimal reconstruction technique following proximal gastrectomy continues. Transhiatal tunnel valvuloplasty (ThTV) is a novel esophagogastrostomy method. This study aimed to evaluate the feasibility and safety of ThTV.
methodsA cohort with upper early gastric cancer or Siewert type II tumors who underwent laparoscopic proximal gastrectomy was retrospectively reviewed in a single center. The ThTV esophagogastrostomy procedure involved placing a lengthy gastric tube into the lower mediastinum and firmly binding it to the esophagus. Demographic and surgical morbidity data were extracted from the medical records.
resultsBetween March 2023 and November 2023, 15 patients underwent laparoscopic proximal gastrectomy using ThTV. The cohort consisted of 13 males and 2 females, with a median age of 68 years (range 49-77). The median operative time was 213 minutes (range 171-370). The median times for tunnel construction and anastomosis were 7 minutes (range 4-30) and 17 minutes (range 10-29), respectively. The median tumor size was 2.0 cm (range 1.0-5.0), and the median number of lymph nodes dissected was 29 (range 13-49). TNM staging revealed 9 cases of stage I, 5 cases of stage II, and 1 case of stage III. As of January 1, 2025, the median follow-up duration was 16.8 months (range 13.8-22.2). No tumor recurrence was observed. No patients reported severe reflux symptoms (Visick score ≥III). Gastroscopy confirmed reflux esophagitis (Los Angeles classification Grade A) in one patient, and an anastomotic stricture requiring endoscopic balloon dilation was observed in another patient.
conclusionsTranshiatal tunnel valvuloplasty is a simple and reliable anti-reflux method following laparoscopic proximal gastric surgery. The further verification of the esophageal function is warranted.
