“…The robotic setup appears to be the more high-grade and promising method for clinical application; clinical realization of the open approach would likely involve disproportionately high morbidity and complications. A case report positively evaluated the robotic surgical system in the placement of a GES system for a patient with medically refractory gastroparesis [34]. Moreover, the robotic surgical system was able to easily access the stomach, duodenum, jejunum, ileum, and colon investigated in this study, but also the rectum and esophagus via small skin incisions.…”

Background: Electrical stimulation (ES) of several gastrointestinal (GI) segments is a promising therapeutic option for multilocular GI dysmotility, but conventional surgical access by laparotomy involves a high degree of tissue trauma. We evaluated a minimally invasive surgical approach using a robotic surgical system to perform electromyographic (EMG) recordings and ES of several porcine GI segments, comparing these data to an open surgical approach by laparotomy. Materials and Methods: In 5 acute porcine experiments, we placed multiple electrodes on the stomach, duodenum, jejunum, ileum, and colon. Three experiments were performed with a median laparotomy and 2 others using a robotic platform. Multichannel EMGs were recorded, and ES was sequentially delivered with 4 ES parameters to the 5 target segments. We calculated pre-and poststimulatory spikes per minute (Spm) and performed a statistical Poisson analysis. Results: Electrode placement was achieved in all cases without complications. Increased technical and implantation time were required to achieve the robotic electrode placement, but invasiveness was markedly reduced in comparison to the conventional approach. The highest calculated (c)Spm values were found in the poststimulatory period of the small bowel with both the conventional and robotic approaches. Six of the 20 Poisson test results in the open setup reached statistical significance and 12 were significant in the robotic experiments. Conclusions: The robotic setup was less invasive, revealed more consistent effects of multilocular ES in several GI segments, and is a promising option for future preclinical and clinical studies of GI motility disorders.
