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

backgroundRobotic-assisted resection of non-adenocarcinoma gastroduodenal tumors offers equivalent oncologic safety while preserving the benefits of minimally invasive surgery. Transoral extraction augments these benefits by reducing the need for a larger extraction incision. This study explores the feasibility of endoscopic transoral extraction of robotically resected gastroduodenal tumors.

methodsPatients underwent robotic gastroduodenal tumor resection by an experienced robotic surgeon. Resected specimens were secured in an EndoCatch bag and retrieved transorally using an upper gastrointestinal endoscope.

resultsFive patients (median age 46 years, 40% female) were included. Patients were ASA class II/III. Tumor sizes ranged from 2.1 to 9.0 cm, located at the gastroesophageal junction, gastric fundus, lesser curvature, and proximal duodenum. Pathological diagnoses included leiomyoma, gastrointestinal stromal tumor (GIST), and glomus tumor. Robotic resection utilized 8-mm abdominal ports. No intraoperative adverse events occurred, and all specimens were retrieved intact. The median console time was 94 min, and 80% of cases had estimated blood loss of less than 20 cc. The median hospital stay was two days. Most patients (80%) resumed clear liquid diet by postoperative day one and progressed to full-liquid diet by day two. No patients required narcotics for postoperative pain management, with 80% managed with oral acetaminophen alone. No esophageal or oropharyngeal complications, readmissions, mortality, or incisional hernias occurred during the follow-up.

conclusionThis case series demonstrates the technical feasibility of robotic-assisted resection of gastroduodenal tumors with structured transoral extraction using real-time endoscopic guidance, representing a technical extension of established NOSES principles in the robotic surgery setting. Prospective multicenter studies are needed to validate safety and broader applicability.
