Introduction: Minimally invasive surgery (MIS) for limited resections for pancreatic uncinate lesions is not widely performed but can adequately treat benign or low-grade malignant lesions. The aim of this study was to evaluate the short-term outcomes of MIS-limited pancreatic resections for patients with suspected pancreatic neuroendocrine tumours (PNETs). Patients and Methods: This was a retrospective study of six consecutive patients who underwent MIS for PNET within a single institution between 2017 and 2022. Results: Six patients underwent limited pancreas-preserving MIS of the uncinate process (uncinectomy or enucleation), of which two were performed through the robotic approach and four through laparoscopic approach. The median operation time was 212.5 (175–338.75) min, and the median blood loss was 50 (50–112.5) ml. The median post-operative hospital length of stay was 5.5 (3.75-11.5) days. Two patients (33.3%) had major post-operative morbidities (Clavien–Dindo ≥Grade 3). There were no open conversions or post-operative mortalities. Five patients had histologically proven Grade 1 neuroendocrine tumours. One was T2 and four were T1. Conclusions: This study suggests that limited MIS resections of pancreatic uncinate PNETs are a feasible procedure with good patient outcomes. It offers a safe alternative to radical surgical resections like pancreatoduodenectomies in selected patients with low-grade malignant or benign tumours.
