Article Abstract
Background: There is much heterogeneity in the instrumentation used for parenchymal transection in minimally invasive liver surgery. Instruments specifically designed for robotic parenchymal transection of the liver are lacking. We aim to gain insight into the safety and effectiveness of the SynchroSeal (Intuitive Surgical, Inc., Sunnyvale, CA), a novel bipolar electrosurgical device, in the context of liver surgery.
Methods: The present study is a post-hoc analysis of prospectively collected data from patients undergoing robotic liver resection (RLR) using the SynchroSeal in two high-volume centres. The results of the SynchroSeal were compared with that of the previous generation bipolar-sealer; Vessel Sealer Extend (Intuitive Surgical, Inc., Sunnyvale, CA) using propensity score matching, after excluding the first 25 Vessel Sealer procedures per center.
Results: During the study period (February 2020-March 2023), 155 RLRs meeting the eligibility criteria were performed with the SynchroSeal (after implementation in June 2021) and 145 RLRs with the Vessel Sealer. Excellent outcomes were achieved when performing parenchymal transection with the SynchroSeal; low conversion rate (n = 1, 0.6%), small amounts of intraoperative blood loss (median 40 mL [IQR 10-100]), short hospital stays (median 3 days [IQR 2-4]), and adequate overall morbidity (19.4%) as well as severe morbidity (11.0%). In a matched comparison (n = 94 vs n = 94), the SynchroSeal was associated with less intraoperative blood loss (48 mL [IQR 10-143] vs 95 mL [IQR 30-200], p = 0.032) compared to the Vessel Sealer. Other perioperative outcomes were similar between the devices.
Conclusion: The SynchroSeal is a safe and effective device for robotic liver parenchymal transection.

Horseshoe kidney (HSK) complicated with renal parenchymal squamous cell carcinoma (RSCC) is exceedingly rare and clinically insidious. Owing to the absence of pathognomonic symptoms or imaging hallmarks, the malignancy is frequently obscured by coexistent renal calculi, hydronephrosis, or infection, resulting in formidable diagnostic challenges, missed diagnoses, and consequently delayed treatment. We report a 60-year-old man who presented with HSK, left renal calculi, and hydronephrosis.

Introduction: Water-Jet (WJ) dissection is an innovative technique for liver surgery that uses high-pressure saline jets to selectively dissect liver parenchyma while preserving vascular and biliary structures. Compared to the Cavitron Ultrasonic Surgical Aspirator (CUSA), WJ offers advantages such as reduced thermal damage, lower blood loss, and shorter operative times. These benefits are particularly important in living-donor liver transplantation (LDLT), where donor safety and rapid recovery are critical.

Background/purpose: A standardized liver parenchymal transection method in robotic-assisted liver resection has not yet been established, and the techniques used vary among institutions. We developed a novel transection technique for robotic-assisted liver resection termed "Trac & Pac," which uses maryland bipolar forceps with a gentle stroking motion and strategic traction to progressively expose and dissect the liver parenchyma.
Methods: We described the technical details of "Trac & Pac" and Evaluated its short-term outcomes (2022-2025), comparing them with those of conventional laparoscopic liver resection using the Cavitron Ultrasonic Surgical Aspirator (CUSA) (2018-2022).

Background: Robotic liver surgery (RLS) has become the preferred minimally invasive approach for liver surgery. However, especially for complex RLS (C-RLS), key surgical steps such as preoperative preparation, intraoperative techniques, and training are often center-dependent and not standardized. The aim of this survey was to assess the international practice of key surgical steps during C-RLS among expert centers.
