Abstract
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.

Abstract
Pancreatic neuroendocrine tumours (pNETs) are rare and heterogeneous group of neoplasms presenting with a wide variety of symptoms and biological behaviour, from indolent to aggressive ones. pNETs are stratified into functional or non-functional, because of their ability to produce metabolically active hormones. pNETs can be an isolate phenomenon or a part of a hereditary syndrome like von Hippel-Lindau syndrome or neurofibromatosis-1. The incidence has increased in the last years, also because of the improvement of cross-sectional imaging. Computed tomography (CT), magnetic resonance imaging (MRI) and functional imaging are the mainstay imaging modalities used for tumour detection and disease extension assessment, due to easy availability and better contrast/spatial resolution. Radiological imaging plays a fundamental role in detection, characterization and surveillance of pNETs and is involved in almost every stage of patients' management. Moreover, with specific indications and techniques, interventional radiology can also play a role in therapeutic management. Surgery is the treatment of choice, consisting of either partial pancreatectomy or enucleation of the primary tumour. This article reviews the radiologic features of different pNETs as well as imaging mimics, in order to help radiologists to avoid potential pitfalls, to reach the correct diagnosis and to support the multidisciplinary team in establishing the right treatment.

Abstract
BACKGROUND Minimally invasive pancreatic surgeries (MIPS) are increasingly adopted worldwide. However, it remains uncertain if these reported experiences are reproducible throughout the world today. This study examines the safety and evolution of MIPS at a single institution in Southeast Asia. METHODS This is a retrospective review of 150 consecutive patients who underwent MIPS between 2006 and 2018 of which 135 cases (90%) were performed since 2012. To determine the evolution of MIPS, the study population was stratified into 3 equal groups of 50 patients. Comparison was also made between pancreatoduodenectomies (PD), distal pancreatectomies (DP) and other pancreatic surgeries. RESULTS One hundred and fifty patients underwent MIPS (103 laparoscopic, 45 robotic and 2 hand-assisted). Forty-three patients underwent PD, 93 DP and 14 other MIPS. There were 21 (14.0%) open conversions. There was an exponential increase in caseload over the study period. Comparison across the 3 time periods demonstrated that patients were significantly more likely to have a higher American Society of Anesthesiologists score, older, undergo PD and a longer operation time. The conversion rate decreased from 28% to 0% and increased again to 14% across the 3 time periods. Comparison between the various types of MIPS demonstrated that patients who underwent PD were significantly older, more likely to have symptomatic tumours, had longer surgery time, increased blood loss, increased frequency of extended pancreatectomies, increased frequency of hybrid procedures, longer post-operative stay, increased post-operative morbidity rate and increased post-operative major morbidity rate. CONCLUSION The case volume of MIPS increased rapidly at our institution over the study period. Furthermore, although the indications for MIPS expanded to include more complex procedures in higher risk patients, there was no change in key perioperative outcomes.

Abstract
Backgrounds/Aims This study aims to describe our experience with minimally-invasive distal pancreatectomies, with emphasis on the comparison between robotic distal pancreatectomy (RDP) and laparoscopic distal pancreatectomy (LDP). Methods Retrospective review of 102 consecutive RDP and LDP from 2006 to 2019 was performed. Results There were 27 and 75 patients who underwent RDP and LDP, respectively. There were 12 (11.8%) open conversions and 16 (15.7%) patients had major (>grade 2) morbidities. Patients who underwent RDP had significantly higher rates of splenic preservation (44.4% vs. 13.3%, p=0.002), higher rates of splenic-vessel preservation (40.7% vs. 9.3%, p=0.001), higher median difficulty score (5 vs. 3, p=0.002) but longer operation time (385 vs. 245 minutes, p<0.001). The rate of open conversion tended to be lower with RDP (3.7% vs. 14.7%, p=0.175). Conclusions In our institution practice, both RDP and LDP were safe and effective. The use of RDP appeared to be complementary to LDP, allowing us to perform more difficult procedures with comparable postoperative outcomes.

Abstract
Despite the potential clinical advantages offered by laparoscopic pancreatic surgery (LPS), the main obstacle to its widespread adoption is the technically demanding nature of the procedure and its steep learning curve. LPS and robotic pancreatic surgery (RPS) have been proven to result in superior short-term perioperative outcomes and equivalent long-term oncological outcomes compared to the conventional open approach, with the caveat that they are performed by expert surgeons who have been trained to perform such procedures. The primary challenge faced by most pancreatic surgeons is the steep learning curve associated with these complex procedures and the need to undergo surgical training, especially with regards to laparoscopic and robotic pancreaticoduodenectomy. Current evidence suggests that RPS may help to shorten the lengthy learning curve required for LPS. More robust evidence—in the form of large randomised controlled trials—is needed to determine whether LPS and RPS can be safely adopted universally.

Abstract
Pancreatic neuroendocrine tumors (PNET) comprise up to 10% of all pancreatic solid tumors. There has been much interest in recent years with regards to the role of limited resection and enucleation procedures for this entity. There is no clear guideline today on the optimal type choice of surgery for this condition, with even fewer reporting on the use of a robotic approach for pancreatic uncinate lesions. We describe a case report of a 54-year-old lady who underwent successful robotic enucleation of pancreatic uncinate neuroendocrine tumor. This patient's recovery was complicated by pancreatitis and a peripancreatic collection, both of which resolved without surgical re-intervention. A literature review was performed with regards to current guidelines on management of PNETs, comparisons between demolitive and parenchymal-preserving procedures, and recent developments in the laparoscopic and robotic approaches for this condition. There is no clear guideline on the optimal type and approach (open vs. laparoscopic vs. robotic) to the surgical management of PNET. We document in this case report a novel approach of robotic enucleation of pancreatic uncinate process NET, that could be considered as an alternative to open/laparoscopic demolitive procedures for small uncinate tumors.
