Abstract
INTRODUCTION The role of parenchyma-sparing resections (PSR) and lymph node dissection in small (<3 cm) nonfunctional pancreatic neuroendocrine tumors (PNET) is unlikely to be studied in a prospective randomized clinical trial. By combining data from 4 high-volume pancreatic centers we compared postoperative and long-term outcomes of patients who underwent PSR with patients who underwent oncologic resections. METHODS Retrospective review of prospectively collected clinicopathologic data of patients who underwent pancreatectomy between 2000 and 2021 was collected from 4 high-volume institutions. PSR and lymph node-sparing resections (enucleation and central pancreatectomy) were compared to those who underwent oncologic resections with lymphadenectomy (pancreaticoduodenectomy, distal pancreatectomy). Statistical testing was performed using χ 2 test and t test, survival estimates with Kaplan-Meier method and multivariate analysis using Cox proportional hazard model. RESULTS Of 810 patients with small sporadic nonfunctional PNETs, 121 (14.9%) had enucleations, 100 (12.3%) had central pancreatectomies, and 589 (72.7%) patients underwent oncologic resections. The median age was 59 years and 48.2% were female with a median tumor size of 2.5 cm. After case-control matching for tumor size, 221 patients were selected in each group. Patients with PSR were more likely to undergo minimally invasive operations (32.6% vs 13.6%, P <0.001), had less intraoperative blood loss (358 vs 511 ml, P <0.001) and had shorter operative times (180 vs 330 minutes, P <0.001) than patients undergoing oncologic resections. While the mean number of lymph nodes harvested was lower for PSR (n=1.4 vs n=9.9, P <0.001), the mean number of positive lymph nodes was equivalent to oncologic resections (n=1.1 vs n=0.9, P =0.808). Although the rate of all postoperative complications was similar for PSR and oncologic resections (38.5% vs 48.2%, P =0.090), it was higher for central pancreatectomies (38.5% vs 56.6%, P =0.003). Long-term median disease-free survival (190.5 vs 195.2 months, P =0.506) and overall survival (197.9 vs 192.6 months, P =0.372) were comparable. Of the 810 patients 136 (16.7%) had no lymph nodes resected. These patients experienced less blood loss, shorter operations ( P <0.001), and lower postoperative complication rates as compared to patients who had lymphadenectomies (39.7% vs 56.9%, P =0.008). Median disease-free survival (197.1 vs 191.9 months, P =0.837) and overall survival (200 vs 195.1 months, P =0.827) were similar for patients with no lymph nodes resected and patients with negative lymph nodes (N0) after lymphadenectomy. CONCLUSION In small <3 cm nonfunctional PNETs, PSRs and lymph node-sparing resections are associated with lower blood loss, shorter operative times, and lower complication rates when compared to oncologic resections, and have similar long-term oncologic outcomes.

Abstract
Background: Laparoscopic technique has been increasingly applied in the treatment of selected pancreatic tumors. The aim of this study is to evaluate the experience with laparoscopic enucleation of pancreatic neoplasms (LEPNs), for selected pancreatic diseases, at a high-volume referral center. Methods: Between May 2012 and October 2020, LEPNs was attempted in 16 patients with selected pancreatic neoplasms. The localization of tumors, etiology, indications, and clinical outcomes were analyzed. Results: Sixteen patients were included. LEPN was successfully performed in 13 patients, 3 conversions to open procedure were required. The definitive histopathological result of the resected pieces showed prevalence of intraductal papillary mucinous neoplasms. Postoperative major complications occurred for 3 patients (18.7%), the 3 of them presented postoperative pancreatic fistula (POPF). The median hospital stay was 4.5 days (range 2-7) for patients without POPF and 14.6 days (3-30) for those who presented with POPF. No deaths were registered. During a median follow-up of 43.8 months (0.2-109), no new-onset exocrine or endocrine insufficiency was diagnosed, no patient experienced tumor recurrence and, the 4 patients who underwent LEPN for insulinoma, remained asymptomatic. Conclusion: LEPNs has become a valuable alternative for patients with benign or low risk of malignancy tumors. Appropriate preoperative imaging is key for localization. Whenever feasible, this technique not only reduces the risks of exocrine and endocrine insufficiency, but also adds the well-known advantages of minimally invasive techniques, making it a safe and feasible treatment.

Abstract
Background In the process of laparoscopic splenic vessels and spleen preservation distal pancreatectomy (LsvSPDP), because the splenic blood vessels have many small branches, how to safely separate the splenic blood vessels from the pancreas has always been the focus and difficulty of this operation. Many cases were switched to laparotomy, or the Warshaw method due to the inability to control bleeding during the separation of the splenic blood vessels. Therefore, we tried to use the selective splenic vascular control method when separating the splenic blood vessels to observe its effect on the conditions of the surgical patients during and after the operation. Methods We retrospectively collected 35 cases of LsvSPDP conducted in our center from September 2015 to December 2020, including 5 males and 30 females. Considering the influence of the surgical learning curve, the cases were divided into three groups. Finally, through statistics of its intraoperative and postoperative conditions, the effectiveness of selective splenic vascular control method can be judged. Results Patients in Group 2 and 3 showed significantly less blood loss (172.5 and 134.44 mL, respectively) compared to patients in Group 1 (541.43 mL; P=0.01). However, the amount of blood loss was not significantly different between Group 2 and 3. Conclusions The amount of bleeding was significantly reduced by splenic blood vessel control technology. And it can improve the success rate of spleen preservation, preserve the success rate of splenic blood vessels, and reduce intraoperative bleeding.
