Investigators reported stable network performance during all remote procedures. The mean latency measured at both the operator and patient sides was 73.29 ± 3.73 ms. Packet loss rates were low — 0.06 ± 0.03% at the operator side and 0.02 ± 0.02% at the patient side. The team recorded upload speeds of 190.89 ± 81.98 Mbps before master–slave operation and 71.22 ± 10.28 Mbps during master–slave operation; corresponding download speeds were 144.00 ± 58.93 Mbps before and 78.13 ± 18.56 Mbps during master–slave operation. No operation lag or signal interruption occurred, and the authors noted uninterrupted master–slave control throughout each procedure.
The series included seven patients: six female, one male. The mean age was 36.4 ± 6.2 years. Two patients had prior abdominal surgery. Comorbid conditions documented in the cohort included hypertension in two patients, diabetes mellitus in one patient, and reflux esophagitis in one patient. The source provided no additional demographic breakdown such as race, detailed medication use, or perioperative risk scores.
Baseline body weight and BMI were reported and then reassessed at 3 months. Mean preoperative body weight was 117.57 ± 17.72 kg, falling to 91.66 ± 8.44 kg at the 3-month visit. Mean BMI decreased from 41.74 ± 4.48 kg/m² preoperatively to 32.67 ± 2.64 kg/m² at 3 months. The investigators calculated short-term efficacy using both %TWL and %EWL: mean %TWL at 3 months was 21.32 ± 6.75%, and mean %EWL was 53.47 ± 13.89%.
These outcomes reflect early postoperative weight loss after sleeve gastrectomy. The source did not report longer-term weight trajectories beyond the 3-month follow-up window.
Antireflux effect was assessed with the GERD-Q instrument. Median preoperative GERD-Q score was 8 (interquartile range 6, 11). At 3 months postoperatively the median GERD-Q score was 6 (interquartile range 6, 7). Investigators reported this numerical decrease but did not provide formal statistical testing or p-values in the abstract, nor did they present a breakdown by individual patient reflux history and the specific anti-reflux maneuvers performed during surgery.
The cohort experienced several early postoperative symptoms and complications. Two patients had dysphagia defined as WST grade ≥2. One patient reported constipation. Two patients experienced chest pain. Two experienced alopecia. Two had abdominal distension. One patient had vomiting. The authors noted temporal patterns: chest pain, abdominal distension, vomiting and dysphagia resolved gradually and spontaneously by the 3-month assessment. In contrast, constipation and alopecia persisted without meaningful change by that timepoint. The source did not report any cases of major surgical morbidity such as staple-line leak, reoperation, or perioperative mortality in the abstract.
The authors concluded that remote robot-assisted sleeve gastrectomy and sleeve gastrectomy with concomitant anti-reflux surgery were safe and feasible in this small, retrospective series of seven patients. The study period spanned October 2025 to March 2026, during which the operator team at Xinjiang Uygur Autonomous Region People's Hospital and the patient-side team at Aksu Prefectural First People's Hospital collaborated on remote procedures.
The source abstract presents descriptive outcomes and short-term follow-up data. The article did not include a detailed formal limitations section within the English abstract; the source did not report longer-term outcomes, comparative controls, or statistical inference in the abstract. Additional methodological details — including exact surgical technique, perioperative protocols, anesthesia considerations, criteria for concomitant anti-reflux procedures, and full safety adjudication procedures — were not provided in the English abstract. These items may be present in the full text, but they are not documented in the source abstract available on PubMed.
Readers should interpret these early results within the context of a small case series with three-month follow-up. The data presented document network feasibility, early weight loss, and short-term changes in GERD-Q scores, together with a spectrum of mostly self-limited postoperative symptoms. The source did not report formal long-term safety or efficacy endpoints beyond the three-month window.
