Background And Objectives: Pheochromocytoma is a challenging tumor type requiring resection with a clear margin and an intact capsule to prevent recurrences. Our aim was to compare perioperative outcomes of laparoscopic adrenalectomy (LA) versus robotic adrenalectomy (RA) for pheochromocytoma.
Methods: In an institutional review board-approved retrospective study, clinical parameters of patients who underwent LA versus RA at a single center were compared using Mann-Whitney U, χ , and survival analyses. Continuous data are expressed as median (interquartile range).
Results: There was a total of 157 patients (RA: n = 87, LA: n = 70) analyzed. Estimated blood loss (36.3 [35.0] vs. 99.9 [65.0] cc, p = 0.020) and hospital stay (1.3 [0.0] vs. 2.2 [1.0] days, p = 0.010) were lower in robotic versus laparoscopic group, respectively. Disease-free and overall survival was similar between groups. The rate of conversion to open for tumors ≥5 cm was less in the robotic group (0% vs. 14%, respectively, p = 0.048).
Conclusion: In this study, long-term outcomes of LA and RA were similar, although adrenalectomies performed robotically were associated with less blood loss, shorter hospital stay, and a lower chance of conversion to open in the case of large tumors.

Objective: The potential of robot-assisted (RA) single-position (SP) lateral lumbar interbody fusion (LLIF) warrants further investigation. This study aimed to assess the efficacy of RA-SP-LLIF in improving both clinical and radiographic outcomes in patients undergoing lumbar spinal fusion surgery.
Methods: A total of 59 patients underwent either RA-SP-LLIF (n = 31 cases) or traditional LLIF (n = 28 cases).

Merging motoneuron and postural synergies in prosthetic hand design for natural bionic interfacing.
Sci Robot
January 2025
Department of Bioengineering, Imperial College of London, London, UK.
Despite the advances in bionic reconstruction of missing limbs, the control of robotic limbs is still limited and, in most cases, not felt to be as natural by users. In this study, we introduce a control approach that combines robotic design based on postural synergies and neural decoding of synergistic behavior of spinal motoneurons. We developed a soft prosthetic hand with two degrees of actuation that realizes postures in a two-dimensional linear manifold generated by two postural synergies.
