Preoperative pancreatic stent placement before the enucleation of insulinoma located in the head and neck of the pancreas in proximity to the main pancreatic duct: study protocol for a multicentre randomised clinical trial in Chinese tertiary medical centres. BMJ Open 2024; 14:e078516. [PMID: 38569703 PMCID: PMC10989159 DOI: 10.1136/bmjopen-2023-078516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Accepted: 02/27/2024] [Indexed: 04/05/2024] Open
Abstract
INTRODUCTION The surgical intervention approach to insulinomas in proximity to the main pancreatic duct remains controversial. Standard pancreatic resection is recommended by several guidelines; however, enucleation (EN) still attracts surgeons with less risk of late exocrine/endocrine insufficiency, despite a higher postoperative pancreatic fistula (POPF) rate. Recently, the efficacy and safety of preoperative pancreatic stent placement before the EN have been demonstrated. Thus, a multicentre open-label study is being conducted to evaluate the efficacy and safety of stent placement in improving the outcome of EN of insulinomas in proximity to the main pancreatic duct. METHODS AND ANALYSIS This is a prospective, randomised, open-label, superiority clinical trial conducted at multiple tertiary centres in China. The major eligibility criterion is the presence of insulinoma located in the head and neck of the pancreas in proximity (≤2 mm) to the main pancreatic duct. Blocked randomisation will be performed to allocate patients into the stent EN group and the direct EN group. Patients in the stent EN group will go through stent placement by the endoscopist within 24 hours before the EN surgery, whereas other patients will receive EN surgery directly. The primary outcome is the assessment of the superiority of stent placement in reducing POPF rate measured by the International Study Group of Pancreatic Surgery standard. Both interventions will be performed in an inpatient setting and regular follow-up will be performed. The primary outcome (POPF rate) will be tested for superiority with the Χ2 test. The difference in secondary outcomes between the two groups will be analysed using appropriate tests. ETHICS AND DISSEMINATION The study has been approved by the Peking Union Medical College Hospital Institutional Review Board (K23C0195), Ruijin Hospital Ethics Committee (2023-314), Peking University First Hospital Ethics Committee (2024033-001), Institutional Review Board of Xuanwu Hospital of Capital Medical University (2023223-002), Ethics Committee of the First Affiliated Hospital of Xi'an Jiaotong University (XJTU1AF2023LSK-473), Institutional Review Board of Tongji Medical College Tongji Hospital (TJ-IRB202402059), Ethics Committee of Tongji Medical College Union Hospital (2023-0929) and Shanghai Cancer Center Institutional Review Board (2309282-16). The results of the study will be published in an international peer-reviewed journal. TRIAL REGISTRATION NUMBER NCT05523778.

Abstract
BACKGROUND Malignant tumours within the proximal pancreas traditionally require pancreaticoduodenectomy (PD) for cure. For smaller lesions with borderline malignant potential the risk/benefit of PD becomes difficult to justify. Robotic approaches to these lesions allow for parenchymal preserving resection with reduced complication profile without oncological compromise. METHODS A review of a single surgeons prospectively collated database across two institutions of consecutive robotic enucleations or parenchyma preserving resections of the proximal pancreas was performed between July 2018 and October 2021. Standard demographic data, preoperative variables, intraoperative parameters, post-operative outcomes, morbidity and mortality were recorded. RESULTS Thirteen patients (8 female and 5 male) underwent robotic enucleation (EN) (8) and/or uncinectomy (UN) (5) in the proximal pancreas. Mean BMI was 32(kg/m2 ). Three patients (21%) underwent preoperative prophylactic pancreatic duct stenting. One patient required conversion to open. The median operative time in the EN group was 170 min (108-224 min) and the UN group was 160 min (110-204 min). The majority (8) of lesions were pNETs. Three lesions were IPMNs, with 1 solitary fibrous tumour and a serous cystic neoplasm (SCN) respectively. Median tumour size was 23 mm (11-58 mm) in the EN group, and 27 mm (17-38 mm) in the UN group. Ten of 13 patients had an R0 resection. There was no mortality in our series. Four (31%) patients across both groups developed clinically relevant POPF while none developed new endocrine or exocrine insufficiency. Average outpatient follow-up has been 6 months (1-18 months). CONCLUSION A robotic approach in proximal parenchymal preserving pancreatectomy is expanding, safe and feasible.

Abstract
The optimal therapy of duodenopancreatic neuroendocrine neoplasia (dpNEN), which occurs in the context of multiple endocrine neoplasia type 1, is still a major challenge and is controversial. Due to the rarity of the disease, there is a lack of prospective randomised studies, so that most recommendations regarding the surgical indication and procedure are based on retrospective case series. In summary, surgical therapy is indicated for non-functional dpNEN > 2 cm, suspected malignancy and functionally active dpNEN. Enucleation or formal pancreatic resections with or without lymphadenectomy may be considered. The aim of therapy should be to eliminate hormone-associated symptoms and prevent an aggressive metastatic disease. At the same time, pancreatic function and quality of life should be preserved in the mostly young patients by resections that save as much parenchyma as possible.

Abstract
Background Tumors involving the main pancreatic duct (MPD) used to be a contraindication for enucleation. Methods Clinical data of consecutive patients with pancreatic tumors who received laparoscopic or robotic enucleation (LEN or REN) between January 2019 and December 2021 at Fudan University Shanghai Cancer Center were analyzed. Results Ninety-six patients were included in the analysis, with 55 in the LEN group and 41 in the REN group, and no conversion to laparotomy. Most tumors were located in the head of pancreas (71.9 %). The tumor diameter (3.1 vs. 1.9 cm) was larger, and more cystic tumors (92.7 % vs. 56.4 %) and more tumors involving the MPD (34.1 % vs. 3.6 %) were observed in the REN group. MPD support tube insertion was performed in 15 cases, with 11 in the REN group and 4 in the LEN group. The incidence of biochemical and grade B postoperative pancreatic fistula (POPF) was both 46.9 %, and no grade C POPF occurred. Among the 45 patients with grade B POPF, 28 cases (62.2 %) were due to carrying drainage tube >3 weeks without additional treatment, and only 4 cases required invasive treatment. For patients with MPD support tube implantation (n = 15), support tube fall-offs were observed in 12 cases, 2 patients had MPD dilatation, and no MPD stricture, stone formation or pancreatic atrophy was observed during follow-up. Conclusions The incidence of POPF was high but still controllable without serious complications after minimally invasive enucleation. The MPD is no longer a restricted area, and the robotic system has advantages in handling complex enucleations.

Abstract
BACKGROUND & AIMS Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is emerging as a safe and effective treatment for pancreatic neuroendocrine tumors. We aimed to compare EUS-RFA and surgical resection for the treatment of pancreatic insulinoma (PI). METHODS Patients with sporadic PI who underwent EUS-RFA at 23 centers or surgical resection at 8 high-volume pancreatic surgery institutions between 2014 and 2022 were retrospectively identified and outcomes compared using a propensity-matching analysis. Primary outcome was safety. Secondary outcomes were clinical efficacy, hospital stay, and recurrence rate after EUS-RFA. RESULTS Using propensity score matching, 89 patients were allocated in each group (1:1), and were evenly distributed in terms of age, sex, Charlson comorbidity index, American Society of Anesthesiologists score, body mass index, distance between lesion and main pancreatic duct, lesion site, size, and grade. Adverse event (AE) rate was 18.0% and 61.8% after EUS-RFA and surgery, respectively (P < .001). No severe AEs were observed in the EUS-RFA group compared with 15.7% after surgery (P < .0001). Clinical efficacy was 100% after surgery and 95.5% after EUS-RFA (P = .160). However, the mean duration of follow-up time was shorter in the EUS-RFA group (median, 23 months; interquartile range, 14-31 months vs 37 months; interquartile range, 17.5-67 months in the surgical group; P < .0001). Hospital stay was significantly longer in the surgical group (11.1 ± 9.7 vs 3.0 ± 2.5 days in the EUS-RFA group; P < .0001). Fifteen lesions (16.9%) recurred after EUS-RFA and underwent a successful repeat EUS-RFA (11 patients) or surgical resection (4 patients). CONCLUSION EUS-RFA is safer than surgery and highly effective for the treatment of PI. If confirmed in a randomized study, EUS-RFA treatment can become first-line therapy for sporadic PI.

Abstract
OBJECTIVE The aim of this study was to assess short- and long-term outcomes including quality of life (QoL) following pancreatic enucleation (PE). BACKGROUND PE is deemed to preserve both the endocrine and the exocrine function while ensuring radicality. However, to assess whether this reflects an actual benefit perceived by patients, QoL has to be considered. METHODS Data from all consecutive patients undergoing PE from January 2010 to December 2019 were retrospectively analyzed. Surgical outcomes were graded according to the Clavien-Dindo classification, and EORTC-C30 and the EORTC-Pan26 were administered as a cross-sectional assessment of QoL. A control group consisting of healthy individuals from the general population was obtained and matched using the propensity score matching method. RESULTS Eighty-one patients underwent PE using the open (59.3%), laparoscopic (27.2%), or robot-assisted (13.5%) approach. Sixty-five (80.2%) patients exhibited functioning/nonfunctioning pancreatic neuroendocrine tumors at final pathology.Surgical morbidity and complications of a Clavien-Dindo grade ≥3 were 48.1% and 16.0%, respectively. In-hospital mortality was 0%. Postoperative pancreatic fistula, post-pancreatectomy hemorrhage, and delayed gastric emptying rates were 21.0%, 9.9%, and 4.9%, respectively.Patients returned the questionnaires after a median of 74.2 months from the index surgery. Postoperative new onset of diabetes mellitus (NODM) was observed in 5 subjects (7.1%), with age being an independent predictor. Seven patients (10.0%) developed postoperative exocrine insufficiency. At the analysis of QoL, all function and symptom scales were comparable between the 2 groups, except for 2 of the EORTC-Pan 26 symptom scales, ("worries for the future" and "body image", P < 0.05). CONCLUSIONS Despite being associated with significant postoperative morbidity, PE provides excellent long-term outcomes. The risk of NODM is low and related to patient age, with QoL being comparable to the general population. Such information should drive surgeons to pursue PE whenever properly indicated.

Abstract
BACKGROUND Risk factors for postoperative pancreatic fistula (POPF) following pancreatic enucleation by the open approach (OpenEN) are well known. However, ENs are more frequently performed laparoscopically (LapEN). The aim of this study was to analyze the risk factors of POPF following LapEN. METHODS AND PATIENTS All patients in our prospective database who underwent LapEN were evaluated. We report the demographics, surgical, early and long-term outcomes. Numerous variables were analyzed to identify the risk factors of POPF. RESULTS From 2008 to 2020, 650 laparoscopic pancreatic resections were performed including 64 EN (10%). The median age was 51 years old (17-79), median BMI was 24 (19-48), and 44 patients were women (69%). The main presentation was an incidental diagnosis (n = 40; 62%), pain (n= 10;16%), and hypoglycemia (n = 8;12%). The main indications were neuroendocrine tumors (40; 63%), mucinous cystadenomas (15; 23%), intraductal papillary mucinous neoplasie (3; 5%), and other benign cysts (6; 9%). Lesions were located on the distal pancreas (43; 67%), head (n = 17; 27%), and neck (4; 6%). The median size was 20 mm (9-110); 30 mm (20-110) for mucinous cystadenoma and 18 mm (8-33) for NET. The median operative time was 90 mn (30-330), median blood loss was 20 ml (0-800) ml, and there were no transfusions and one conversion. There were no mortalities and overall morbidity (n = 22; 34%) included grades B and C POPF (10;16%) and post-pancreatectomy hemorrhage (4; 6%). The median hospital stay was 7 days (3-42). There were no invaded lymph nodes and all cystic lesions were nonmalignant. After a mean follow-up of 24 months, there was no recurrence. The risk factors for grades B/C POPF were mucinous cystadenoma and proximity to the Wirsung duct < 3 mm. CONCLUSION In this series, the outcome of LapEN was excellent with no mortality and a low rate of morbidity. However, the risk of POPF is increased with cystic lesions and those close to the Wirsung duct.

Abstract
RATIONALE We describe a case of insulinoma located extremely close to the accessory pancreatic duct (APD), but away from the main pancreatic duct (MPD). Previous studies showed insulinoma enucleation is a safe procedure for small benign tumors >3 mm distant from the MPD. However, in this case enucleation of the tumor led to unanticipated APD injury and grade B post-operative pancreatic fistula (POPF). We provide detailed records of clinical management and argue that enucleation of tumors near APD needs to be carefully weighed. PATIENT CONCERNS The patient experienced a sudden increase of abdominal drain fluid and prolonged drainage time after a regular insulinoma enucleation surgery. DIAGNOSIS APD damage during the enucleation. INTERVENTIONS Drain fluid amylase concentration were regularly recorded and prolonged somatostatin analogs were administered. OUTCOMES Amount of abdominal drain gradually decreased and the drain tube was removed on postoperative 37. LESSONS Benign pancreatic tumor close to the APD need to be evaluated carefully and clinical evidence is warranted to affirm the necessity of placing a pancreatic duct stent before the surgery.

Abstract
Background: A minimal distance of 3 mm to main pancreatic duct (MPD) was generally considered to be necessary for pancreatic enucleation (PE). This study was designed to report the safety and feasibility of PE for tumors located in 3 mm to MPD Under the intraoperative ultrasound (IOUS) guidance.Methods: The data of patients who received IOUS guided robotic PE from January 2018 to May 2019 in the second department of hepato-pancreato-biliary surgery were reviewed in this study. According to the distance to MPD (less than 3 mm or not), patients were divided in 2 groups, and the short-term operative outcomes were compared.Statistics: Students' t-test and Mann-Whitney U test were used for comparing continuous variables, and Chi-squared test was used for comparing categorical variables.Results: And a total of 56 patients were analyzed, and a minimal distance less than 3 mm between the tumor and pancreatic duct measured by IOUS was found in 12 patients. The tumors and MPD were clearly revealed intraoperatively in all the cases. The operative duration was significantly longer in patients with tumors located in 3 mm from MPD (143.25 ± 40.89 min vs 107.14 ± 37.73 min, t = 2.756, P=.014). There was no significant difference between the rate of post-operative pancreatic fistula and other complications in the different groups (χ2 =.924, P=.48).Discussion and conclusion: robotic PE could be safely performed under IOUS guidance for benign or low-grade malignant tumors located less than 3 mm to the MPD.

Abstract
Solid pseudopapillary neoplasms (SPNs) of the pancreas are rare, low-grade, malignant neoplasms that are mostly seen in young women in the second and third decades of life and are quite uncommon in children. Standard resection for benign and borderline neoplasms of the pancreas is associated with a substantial risk of postoperative morbidity and long-term functional impairment, whereas enucleation leads to less morbidity and preserves healthy parenchyma as well as exocrine and endocrine function. Enucleation of SPNs has been increasingly reported to be feasible and safe for preserving the normal physiological function of the pancreas, especially in teenagers and children. This review summarizes findings published in recent years on the enucleation of SPNs as well as potential future developments and directions. Enucleation has undoubtedly come to stay as an alternative surgical procedure for SPNs. However, many questions remain unresolved, and future directions toward the best surgical indication, the prevention and intervention of complications, especially pancreatic fistula, intraoperative resection margin safety assessment, and long-term oncology prognosis remain to be evaluated and should be explored in future clinical trials.

Abstract
Pancreatic neuroendocrine neoplasms (panNENs) are a heterogeneous group of tumors derived from cells with neuroendocrine differentiation. They are considered malignant by default. However, their outcomes are variable depending on their presentation in the onset of hereditary syndromes, hormonal secretion, grading, and extension. Therefore, although surgical treatment has long been suggested as the only treatment of pancreatic neuroendocrine neoplasms, its modalities are an evolving landscape. For selected patients (small, localized, non-functional panNENs), a "wait and see" strategy is suggested, as it is in the setting of multiple neuroendocrine neoplasia type 1, but the accurate size cut-off remains to be established. Parenchyma-sparring pancreatectomy, aiming to limit pancreatic insufficiency, are also emerging procedures, which place beyond the treatment of insulinomas and small non-functional panNENs (in association with lymph node picking) remains to be clarified. Furthermore, giving the fact that the liver is generally the only metastatic site, surgery keeps a place of choice alongside medical therapies in the treatment of metastatic disease, but its modalities and extensions are still a matter of debate. This narrative review aims to describe the current recommended surgical management for pancreatic NENs and controversies in light of the actual recommendations and recent literature.

Estimation of pancreatic fibrosis and prediction of postoperative pancreatic fistula using extracellular volume fraction in multiphasic contrast-enhanced CT. Eur Radiol 2021; 32:1770-1780. [PMID: 34636963 DOI: 10.1007/s00330-021-08255-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 07/30/2021] [Accepted: 08/07/2021] [Indexed: 11/27/2022]
Abstract
OBJECTIVE To investigate the diagnostic performance of the extracellular volume (ECV) fraction in multiphasic contrast-enhanced computed tomography (CE-CT) for estimating histologic pancreatic fibrosis and predicting postoperative pancreatic fistula (POPF). METHODS Eighty-five patients (49 men; mean age, 69 years) who underwent multiphasic CE-CT followed by pancreaticoduodenectomy with pancreaticojejunal anastomosis between January 2012 and December 2018 were retrospectively included. The ECV fraction was calculated from absolute enhancements of the pancreas and aorta between the precontrast and equilibrium-phase images, followed by comparisons among histologic pancreatic fibrosis grades (F0‒F3). The diagnostic performance of the ECV fraction in advanced fibrosis (F2‒F3) was evaluated using receiver operating characteristic curve analysis. Multivariate logistic regression analysis was used to evaluate the associations of the risk of POPF development with patient characteristics, histologic findings, and CT imaging parameters. RESULTS The mean ECV fraction of the pancreas was 34.4% ± 9.5, with an excellent intrareader agreement of 0.811 and a moderate positive correlation with pancreatic fibrosis (r = 0.476; p < 0.001). The mean ECV fraction in advanced fibrosis was significantly higher than that in no/mild fibrosis (44.4% ± 10.8 vs. 31.7% ± 6.7; p < 0.001), and the area under the receiver operating characteristic curve for the diagnosis of advanced fibrosis was 0.837. Twenty-two patients (25.9%) developed clinically relevant POPF. Multivariate logistic regression analysis demonstrated that the ECV fraction was a significant predictor of POPF. CONCLUSIONS The ECV fraction can offer quantitative information for assessing pancreatic fibrosis and POPF after pancreaticojejunal anastomosis. KEY POINTS • There was a moderate positive correlation of the extracellular volume (ECV) fraction of the pancreas in contrast-enhanced CT with the histologic grade of pancreatic fibrosis (r = 0.476; p < 0.001). • The ECV fraction was higher in advanced fibrosis (F2‒F3) than in no/mild fibrosis (F0‒F1) (p < 0.001), with an AUC of 0.837 for detecting advanced fibrosis. • The ECV fraction was an independent risk factor for predicting subclinical (odds ratio, 0.81) and clinical (odds ratio, 0.80) postoperative pancreatic fistula.

Risk factors and prevention of postoperative pancreatic fistula after insulinoma enucleation:a retrospective study from a high-volume center. Pancreatology 2021; 21:S1424-3903(21)00475-0. [PMID: 34116940 DOI: 10.1016/j.pan.2021.06.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 05/24/2021] [Accepted: 06/01/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND/OBJECTIVES Enucleation is an effective surgical method to treat pancreatic insulinoma, however, the incidence of clinically relevant postoperative pancreatic fistula (CR-POPF) is high. We aim to investigate the risk factors for CR-POPF which have not been well characterized and develop effective methods to prevent CR-POPF after enucleation. METHODS This retrospective cohort study included 161 patients diagnosed with insulinoma from June 2016 to July 2020 in Peking Union Medical College Hospital. The risk factors for CR-POPF were evaluated and the role of prophylactic pre-operative pancreatic stent to prevent the occurrence of CR-POPF after enucleation of pancreatic insulinoma were explored. RESULTS A cohort of 161 insulinoma cases were reviewed. The CT or MRI imaging reports could be tracked in 108 cases. A total of 96 patients underwent surgery, while 81 experienced pancreatic enucleation. Univariate and multivariate analyses showed that the distance from insulinoma to the main pancreatic duct (MPD) ≤2 mm was an independent risk factor for CR-POPF (p = 0.003, OR = 6.011, 95% Cl 1.852-19.512). The pre-operative pancreatic stent substantially reduced the incidence of CR-POPF in patients with tumor located in proximity to (distance ≤2 mm) the MPD (CR-POPF of the stented group vs the non-stented group: 37.5% vs 71.4%, p = 0.028). CONCLUSIONS The distance from insulinoma to MPD ≤2 mm is a predictive factor for CR-POPF after enucleation. Pancreatic duct stenting may benefit patients with insulinoma in proximity to the MPD by enabling a lower CR-POPF rate, so it should be considered before the enucleation of the insulinoma in proximity to the MPD (distance ≤2 mm).

Abstract
BACKGROUND The feasibility and safety of minimally invasive enucleation (ME) for benign or borderline pancreatic tumors is still unclear. The aim of this study was to compare outcomes between ME and open enucleation (OE). METHODS All patients undergoing pancreatic enucleation between October 2001 and January 2020 were analyzed from a prospective database. Consecutive patients undergoing ME were compared with patients undergoing OE in a matched-pair analysis (1:2). RESULTS Of 358 patients, undergoing enucleation, 120 matched patients (ME n = 40, OE n = 80) were included. Patients undergoing ME had less blood loss (median 50 vs. 100 ml, P = 0.025) and had a higher proportion of patients discharged by 7 days, than patients undergoing OE (38% vs. 18%, P = 0.016). The rates of clinically relevant postoperative pancreatic fistula (POPF) and major complications (Clavien grade ≥ 3) were similar between both groups. Risk factor analysis for POPF B/C showed no significant parameters associated with POPF, including tumor size and proximity to the main pancreatic duct. CONCLUSION Compared with conventional OE, ME reduces the amount of bleeding and allows earlier postoperative discharge, without increasing the incidence of major complications. Thus, minimally invasive enucleation should be considered for benign tumors of the pancreas when technically and oncologically feasible.

Indications and outcomes of enucleation versus formal pancreatectomy for pancreatic neuroendocrine tumors. HPB (Oxford) 2021; 23:413-421. [PMID: 32771338 DOI: 10.1016/j.hpb.2020.06.015] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 06/23/2020] [Accepted: 06/25/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Pancreatoduodenectomy (PD) or distal pancreatectomy (DP) are common procedures for patients with a pancreatic neuroendocrine tumor (pNET). Nevertheless, certain patients may benefit from a pancreas-preserving resection such as enucleation (EN). The aim of this study was to define the indications and differences in long-term outcomes among patients undergoing EN and PD/DP. METHODS Patients undergoing resection of a pNET between 1992 and 2016 were identified. Indications and outcomes were evaluated, and propensity score matching (PSM) analysis was performed to compare long-term outcomes between patients who underwent EN versus PD/DP. RESULTS Among 1034 patients, 143 (13.8%) underwent EN, 304 (29.4%) PD, and 587 (56.8%) DP. Indications for EN were small size (1.5 cm, IQR:1.0-1.9), functional tumors (58.0%) that were mainly insulinomas (51.7%). After PSM (n = 109 per group), incidence of postoperative pancreatic fistula (POPF) grade B/C was higher after EN (24.5%) compared with PD/DP (14.0%) (p = 0.049). Median recurrence-free survival (RFS) was comparable among patients who underwent EN (47 months, 95% CI:23-71) versus PD/DP (37 months, 95% CI: 33-47, p = 0.480). CONCLUSION Comparable long-term outcomes were noted among patients who underwent EN versus PD/DP for pNET. The incidence of clinically significant POPF was higher after EN.

Incidence and impact of Textbook Outcome among patients undergoing resection of pancreatic neuroendocrine tumors: Results of the US Neuroendocrine Tumor Study Group. J Surg Oncol 2020; 121:1201-1208. [PMID: 32185804 DOI: 10.1002/jso.25900] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Accepted: 02/29/2020] [Indexed: 01/11/2023]
Abstract
BACKGROUND AND OBJECTIVES We sought to define the incidence and impact of Textbook Outcome (TO) on disease-free survival [DFS] among patients undergoing resection of pancreatic neuroendocrine tumors (PNET). METHODS Patients undergoing resection of a PNET between 2000 and 2016 were identified using a multi-institutional database. TO was defined as no postoperative severe complications (Clavien-Dindo grade ≥ III), no 90-day mortality, no prolonged length-of-hospital stay (LOS) (ie, > 75th percentile), no 90-day readmission after discharge, and R0 resection. The 5-year DFS was calculated and the association with TO was examined. RESULTS Among 821 patients with a PNET, median tumor size was 2.1 cm (IQR 1.4-14.6). Resection consisted of pancreatoduodenectomy (PD) (n = 231, 28.1%), distal pancreatectomy (DP) (n = 492, 59.9%), and enucleation (EN) (n = 98, 11.9%). Overall TO rate was 49.3% (n = 405). The incidence of TO varied by procedure type (PD: 32.5% vs DP: 56.7% vs EN: 52.0%; P < .001). After adjusting for all competing factors, achievement of a TO was independently associated with improved DFS (hazard ratio: 0.54, 95% CI, 0.35-0.81; P = .003). CONCLUSIONS Only one in two patients undergoing resection of a PNET achieved a TO, which varied markedly based on procedure type. Achievement of a TO was associated with improved DFS.

Abstract
BACKGROUND Pancreatic enucleation (PE) is a viable option for the removal of non-malignant pancreatic masses leading to complete preservation of organ function. Nevertheless, PE is associated with substantial rates of post-operative pancreatic fistula (POPF), particularly when the mass is close to the main pancreatic duct (MPD). Preoperative stenting of the MPD may prevent its injury when performing PE. This paper describes a novel technique of "deep" PE preceded by endoscopic stenting of the MPD. METHODS From January 2017 to May 2019, patients with small pancreatic neuroendocrine tumors proximal to the MPD were candidates for PE with previous stenting of the MPD at the University of Verona, Italy, and at the UCLA Medical Center, Los Angeles, California. The endoscopic stenting was scheduled either the day before or 3 weeks before surgery, depending on the participating institute. RESULTS Ten patients were included in this pilot study. The endoscopic procedure was successful and well tolerated in all cases. Open, laparoscopic and robotic PE were performed. Seven patients had surgical complications. Among these, six developed a post-operative pancreatic fistula (POPF), but neither grade C fistulas nor disruptions of the MPD were detected. At pathology, a low grade pancreatic neuroendocrine tumor was confirmed in all cases. CONCLUSION In the setting of high-volume centers, this procedure is safe, and it is associated with acceptable short-term surgical morbidity. The preoperative stenting of the MPD might extend the surgical indications for PE.

Propensity score-matched analysis of clinical outcome after enucleation versus regular pancreatectomy in patients with small non-functional pancreatic neuroendocrine tumors. Pancreatology 2020; 20:169-176. [PMID: 31941586 DOI: 10.1016/j.pan.2019.12.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Revised: 10/19/2019] [Accepted: 12/11/2019] [Indexed: 12/11/2022]
Abstract
OBJECTIVES The effectiveness of enucleation in treatment for low-grade (G1, G2) small (≤2 cm) non-functional pancreatic neuroendocrine tumors (sNF-pNETs) remains controversial. This study investigated short- and long-term outcome of enucleation comparing with regular pancreatectomy in patients with sNF-pNETs. METHODS The clinical data of patients with sNF-pNETs who underwent surgery in our hospital from January 2000 to December 2017 were retrospectively collected. Short- and long-term outcomes of two operations were analyzed. The propensity score matching (PSM) was performed to reduce potential selection bias. RESULTS A total of 123 patients with sNF-pNETs were enrolled with 62 males, 69 G1, and median age was 56.91 ± 10.04 years old. During the follow-up period (mean 87 ± 58.1 months), 9(7.32%) disease progressed (recurrence or metastasis) and 2 died (1.62%), 5-years OS was 100%, 5-years DFS was 91.4%. Both lymph node metastasis (p = 0.117) and pathological grade (p = 0.050) were not prognostic factors for sNF-pNETs. The propensity score-matched cohort comprised 27 patients with enucleation and 44 patients with regular pancreatectomy. Enucleation was noninferior to regular pancreatectomy in terms of DFS, before or after PSM. The surgical duration (P < 0.01) and blood loss (P < 0.01) significantly decreased in enucleation compared with regular pancreatectomy. The other postoperative complications tended to occur in regular pancreatectomy than in enucleation, but no statistically significant difference (all p > 0.05). CONCLUSION Enucleation seems to be an effective option for the treatment of sNF-pNETs with a lower total rate of postoperative complications and similar long-term prognosis, compared with regular pancreatectomy.

Abstract
BACKGROUND The most hazardous complication to pancreatic surgery is the development of a post-operative pancreatic fistula (POPF). Appropriate understanding of the underlying pathophysiology, risk factors and perioperative mechanisms may allow for better management and use of preventive measures. METHODS Systematic literature search using the English PubMed literature up to April 2019, with emphasis on the past 5 years. RESULTS Several risk scores have been developed but none are perfect in predicting POPF risk. A conceptual framework of factors that contribute to the pathophysiology of pancreatic fistulae is still developing but incomplete. Recognized factors include those related to the patient, the pathology and the perioperative care. Interventions such as use of drains, stents and various drugs to mediate risk is still debated. Emerging data suggest that both the microbiome and the inflammation in the post-operative phase may play important roles in risk for POPF. Available risk scores allow for stratification of risk and mitigation strategies tailored to reduce this. However, accurate estimation of risk remains a challenge and mechanisms are only partially understood. CONCLUSIONS The pathophysiology of POPF remains poorly understood. Current models only partially explain risks or associated mechanisms. Novel areas of investigation need to be explored for better prediction.

Abstract
BACKGROUND Enucleation has become an alternative treatment in benign or low-malignant cystic tumors, including intraductal papillary mucinous neoplasms (IPMN). For enucleation to be a safe alternative to the standard procedures, there must be good access to the resection area. In this report, we present such a route for dorsally situated IPMNs. METHODS The head of the pancreas was exposed by an extended Kocher maneuver to the left lateral edge of the aorta. Stay sutures were placed along the second part of the duodenum to allow maximal rotation of the pancreatic head to the left, which exposed the posterior aspect of the pancreatic head. The cystic lesion was then enucleated followed by a protective pancreaticojejunostomy on the resection cavity. RESULTS Two consecutive patients with IPMNs of the dorsal pancreatic head successfully underwent dorsal enucleation. The postoperative course was uneventful in the first patient, while the course of the second patient was complicated by a clinically relevant pancreatic fistula, delayed gastric emptying, and hospital discharge on day 35. CONCLUSION This study shows the feasibility of a dorsal approach to the pancreatic head for enucleation as well as reconstruction by means of posterior Roux-en-Y pancreaticojejunostomy. In very selected cases in specialized centers, cystic lesions in the posterior aspect of the pancreatic head will become amenable to enucleation with preservation of pancreatic functionality. However, more research is needed to clarify postoperative outcomes of this approach.

Abstract
OBJECTIVES The purpose of this study was to evaluate the diagnostic performance of magnetization transfer (MT) imaging and multigradient echo magnetic resonance imaging (MRI) to quantify pancreatic fibrosis and lipomatosis in patients before pancreatoduodenectomy for postoperative risk stratification with histopathology as the reference standard. MATERIALS AND METHODS Twenty-four patients (age, 68 ± 8 years, 16 males) prospectively underwent quantitative MT imaging using a 2-dimensional gradient echo sequence with and without MT prepulse and multigradient echo imaging on a 3 T MRI 1 day before pancreatoduodenectomy due to adenocarcinoma of the pancreatic head region (n = 20), neuroendocrine tumor (n = 3), or intraductal papillary mucinous neoplasm (n = 1). Magnetization transfer ratio (MTR) and proton density fat fraction (PDFF) were measured in pancreatic tail (PT) and at the resection margin (RM). Histopathologically, pancreatic fibrosis was graded as mild, moderate, or severe (F1-F3), lipomatosis was graded as 0% to 10%, 11% to 30%, and greater than 30% fat deposition (L1-L3). In addition, MTR and histopathologic fibrosis was assessed in pancreatic adenocarcinoma. Mann-Whitney U test and Spearman correlation were used. RESULTS Patients with advanced pancreatic fibrosis (F3) showed a significantly higher MTR compared with the F1 group at the RM and PT (38 ± 4 vs 32.3 ± 1.6, P = 0.018 and 39.7 ± 5.5 vs 31.2 ± 1.7, P = 0.001). Spearman correlation coefficient of MTR and fibrosis grade was r = 0.532 (P = 0.011) and 0.554 (P = 0.008), respectively. Pancreatic parenchyma with advanced fat deposition (L2-L3) showed significantly higher PDFF compared with lipomatosis grade L1 (RM: P = 0.002 and PT: P = 0.001). Proton density fat fraction of pancreatic parenchyma exhibited a moderate and significant correlation with histopathologic lipomatosis grade (RM: r = 0.668 and PT: r = 0.707, P < 0.001). Magnetization transfer ratio was significantly higher in pancreatic adenocarcinoma compared with pancreatic parenchyma (44 ± 5.5 vs 36.0 ± 4.4 and 37.4 ± 5.4, P = 0.004). CONCLUSIONS Multiparametric MRI of the pancreas including MTR and PDFF maps may provide quantitative and noninvasive information on pancreatic fibrosis and lipomatosis before surgery.

Abstract
Small (<2 cm) sporadic neuroendocrine pancreatic neoplasms (pNENs) are a heterogeneous group of neoplasms, which can be separated into functionally active or non-functional tumors. Functionally active pNENs release various hormones, such as insulin, gastrin, glucagon and vasoactive intestinal hormones and therefore lead to severe symptoms independent of their size. The main symptoms include hypoglycemia, coma (insulinoma), diarrhea (gastrinoma, VIPoma), intestinal ulcers (gastrinoma) and hyperglycemia (glucagonoma). Asymptomatic inactive pNENs do not cause a hormonal syndrome even though in immunohistochemistry they are positive for various hormones and endocrine markers (e.g. chromogranin and synaptophysin). Non-active small pNENs are increasingly being found because of the widespread use of high-resolution imaging and are named incidental pNENs. The current therapy algorithms of small functionally active and non-functional pNENs are very different and include besides non-operative management and surveillance (wait and see strategy) of non-active pNENs (G1, low G2), all minimally invasive, open and robotic techniques of pancreas resection. Until today almost all recommendations of surgical and nonsurgical therapy algorithms have been established based on retrospective data.

Abstract
Natural history of gastroenteropancreatic (GEP) Neuroendocrine tumors (NETs) is better and better known so indications of surgery are presently selective. Surgical resection, but also endoscopic resection and observation, can be proposed for gastric NETs according to presentation, size and grade. For small bowel NETs, resection is frequently needed but should obtain the best compromise between radicality and postoperative functional disorders. Appendiceal NETs are frequently diagnosed by appendectomy for appendicitis, but some patients at high risk for lymph node metastasis and recurrence should be reoperated for radical resection. Rectal NETs are often diagnosed incidentally; the smallest (<1cm) can be resected endoscopically but the most aggressive need a oncological proctectomy. Pancreatic NETs represent a wide spectrum, ranging from fully benign tumors to very aggressive ones. Insulinomas are mostly benign, responsible for incapacitating symptoms despite medical treatment, and should ideally be treated by parenchyma sparing resection, mainly enucleation. Conversely, symptoms of gastrinomas are efficiently treated medically but their resection needs an oncological approach. Nonfunctioning PNETs are more and more frequently and incidentally discovered. According to their size, presentation and patient's characteristics, they need a resection (oncological or parenchyma-sparing) or a close observation.

Abstract
Background To determine predictive factors of postoperative pancreatic fistula (POPF) in patients undergoing enucleation (EN). Methods From 2005 to 2017, 47 patients underwent EN and had magnetic resonance imaging available for precise analysis of tumor location. Three pancreatic zones were delimited by the right side of the portal vein and the main pancreatic head duct (zone #3 comprising the lower head parenchyma and the uncinate process). Results The mortality and morbidity rates were 0% and 62%, respectively. POPF occurred in 23 patients (49%) and was graded as B or C (severe) in 15 patients (32%). Four patients (8.5%) developed a postoperative hemorrhage, and 5 patients (11%) needed a reintervention. In univariate and multivariate analyses, the pancreatic zone was the unique predictive factor of overall (P = .048) or severe POPF (P = .05). We did not observe any difference in postoperative courses when comparing the EN achieved in zones #1 and #2. We noted a longer operative duration (P = .016), higher overall (P = .017) and severe POPF (P = .01) rates, and longer hospital stays (P = .04) when comparing the EN achieved in zone #3 versus that in zones #1 and #2. Patients who underwent EN in zone #3 had a relative risk of developing a severe POPF of 3.22 compared with patients who underwent EN in the two other pancreatic zones. Conclusion Our study identifies the lower head parenchyma and the uncinate process as a high-risk zone of severe POPF after EN. Patients with planned EN in this zone could be selected and benefit from preoperative and/or intraoperative techniques to reduce the severe POPF rate.

Abstract
Incidental diagnosis of pancreatic neuroendocrine tumors (PanNETs) greatly increased in the last years. In particular, more frequent diagnosis of small PanNETs leads to many challenging clinical decisions. These tumors are mostly indolent, although a percentage (up to 39%) may reveal an aggressive behaviour despite the small size. Therefore, there is still no unanimity about the best management of tumor smaller than 2 cm. The risks of under/overtreatment should be carefully evaluated with the patient and balanced with the potential morbidities related to surgery. The importance of the Ki-67 index as a prognostic factor is still debated as well. Whenever technically feasible, parenchyma-sparing surgeries lead to the best chance of organ preservation. Lymphadenectomy seems to be another important prognostic issue and, according to recent findings, should be performed in noninsulinoma patients. In the case of enucleation of the lesion, a lymph nodal sampling should always be considered. The relatively recent introduction of minimally invasive techniques (robotic) is a valuable option to deal with these tumors. The current management of PanNETs is analysed throughout the many available published guidelines and evidences with the aim of helping clinicians in the difficult decision-making process.

Abstract
OBJECTIVE The aim of this study was to evaluate the safety and efficiency of enucleation (EU) for proximal pancreatic non-invasive neoplasms. METHODS Patients with solitary non-invasive neoplasms in the proximal pancreas from January 1998 to April 2014 at the Second Affiliated Hospital of Zhejiang University, Hangzhou, China were included. Different operations and outcomes were analyzed. RESULTS A total of 123 patients were enrolled. Forty patients (32.5%) underwent EU including 18 patients who had tumors close to the main pancreatic duct (MPD). Sixty-one patients (49.6%) had pancreaticoduodenectomy (PD) performed and 22 (17.9%) underwent central pancreatectomy (CP). Pathological outcomes included neuroendocrine tumors, cystic lesions, and solid pseudopapillary tumors. Operation time, intra-operative blood loss, and duration of hospital stay were significantly reduced in the EU group. PD was associated with the greatest complication rate (55.7%), followed by EU (50%) and CP (40.9%), though the pancreatic fistula rate after EU was the highest (50%), especially in patients with tumors larger than 3 cm and tumors close to the MPD. EU had advantages in the preservation of pancreatic parenchyma and endocrine and exocrine function. CONCLUSIONS EU can be carried out safely and effectively for tumors in the proximal pancreas with improved outcomes compared with standard resections, even if the tumor is larger than 3 cm and close to the MPD.

Abstract
Neuroendocrine tumors of the pancreas (pNETs) are a rare group of neoplasms that originate from the endocrine portion of the pancreas. Tumors that either secrete or do not secrete compounds, resulting in symptoms, can be classified as functioning and non-functioning pNETs, respectively. The prevalence of such tumors has recently increased due to the use of more sensitive imaging techniques, such as multidetector computed tomography, magnetic resonance imaging and endoscopic ultrasound. The biological behavior of pNETs varies widely from indolent, well-differentiated tumors to those that are far more aggressive. The most effective and radical treatment for pNETs is surgical resection. Over the last decade, minimally invasive surgery has been increasingly used in pancreatectomy, with laparoscopic pancreatic surgery (LPS) emerging as an alternative to open pancreatic surgery (OPS) in patients with pNETs. Non-comparative studies have shown that LPS is safe and effective. In well-selected groups of patients with pancreatic lesions, LPS was found to results in good perioperative outcomes, including reduced intraoperative blood loss, postoperative pain, time to recovery, and length of hospital stay. Despite the encouraging results of studies from highly specialized centers with extensive experience, no randomized trials to date have conclusively validated these findings. Indications for minimally invasive LPS for patients with pNETs remain unclear. This review presents the current state of LPS for pNETs.

Abstract
The aim of this study was to assess the feasibility of prophylactic pancreatojejunostomy after enucleation or limited pancreatic resection regarding the risk of postoperative pancreatic fistula (PF). We retrospectively reviewed the medical records of 32 patients who underwent enucleation or limited pancreatic resection and compared the clinical parameters between patients with ( n = 10) and without ( n = 22) prophylactic pancreatojejunostomy. Prophylactic pancreatojejunostomy was performed in patients with a possible high risk ofPF. No operation-related mortality occurred. Operation time was significantly longer ( P < 0.01) and blood loss significantly greater ( P < 0.01) in patients with pancreatojejunostomy. Overall complications were more frequent ( P = 0.02) and postoperative hospital stay was significantly longer ( P = 0.02) in patients with pancreatojejunostomy. However, other assessed factors including the prevalence of postoperative PF did not differ between groups. In conclusion, prophylactic pancreatojejunostomy is feasible, and its efficacy in preventing PF after enucleation or limited pancreatic resection in high-risk patients will require further study.

Abstract
BACKGROUND Enucleation is increasingly used for benign or low-grade pancreatic neoplasms. Enucleation preserves the pancreatic parenchyma as well as decreases the risk of long-term endocrine and exocrine dysfunction, but may be associated with a higher rate of postoperative pancreatic fistula (POPF). The aim of this study was to assess short-term outcomes, in particular, POPF. METHODS Data were collected retrospectively from all 142 patients who underwent pancreatic enucleation between 2009 and 2014 in our institution were analyzed. RESULTS Lesions were most frequently located in the head and uncinate process of the pancreas (60.6%), and the most common types were neuroendocrine neoplasms (52.1%). Overall morbidity was 66%, mainly due to POPF (53.5%), and severe morbidity was only 8.4%, including one death (0.7%). Clinical POPF (Grade B or C) occurred in 22 patients (15.5%). Independent risk factors for clinical POPF were age ≥60 years, an episode of acute pancreatitis, and cystic morphology. Tumor size, coverage, histological differentiation, and prolonged operative time were not associated with the risk of POPF. CONCLUSIONS Enucleation is a safe and feasible procedure for benign or low-grade pancreatic neoplasms. The rate of clinical POPF is acceptable, and clinical POPF occurs more frequently in elderly patients (≥60 years of age), patients with cystic neoplasms, or patients with an episode of acute pancreatitis.

Abstract
Pancreatic endocrine neoplasias (pNENs) are uncommon but fascinating tumors with a rising incidence. In accordance to its location, size and grading, the decision to operate the patient should always be made in an interdisciplinary approach. This article provides a comprehensive review of the current literature addressing the current challenges in pNEN surgery and shows that patients with completely resected small pNENs generally have an excellent prognosis, but also that surveillance may be a powerful tool.

Abstract
BACKGROUND The incidence of nonfunctioning pancreatic neuroendocrine tumors smaller than 2cm has increased remarkably in the last two decades. Controversies exist regarding whether surgery should be conducted for this group of tumors. METHODS MEDLINE, EMBASE and CENTRAL were search until 2017/01/17. Studies with comparative results between operation and observation group were included. Primary outcomes were overall survival and disease specific survival. Secondary outcomes were disease progression and surgical death and complications. RESULTS 6 studies with a total of 1861 patients were identified. No randomized controlled trials were found. Survival rate was high (97-100%) and no patients died because of the disease in 5 of the 6 studies, with no difference between operation and observation group. Disease progression was compared in 3 of the 6 studies. 2 studies reported minimal disease progression (0-3.5%) and no significant difference between operation and observation group. Perioperative deaths were rare (0-3%), but complications were common (33-46%). None of the 46 patients who crossed over form observation to operation group had disease recurrence after resection. CONCLUSION Small NF-PNETs without distant metastasis, lymph node metastasis and local invasion on imaging studies can be observed without increase in death and disease progression.

Abstract
BACKGROUND Non-functional pancreatic neuroendocrine tumors (NF-PNET) are rare neoplasms being increasingly diagnosed. Surgical treatment or expectant management are both suggested for small NF-PNETs. The aim of this study was to evaluate the outcome of surveillance strategy for small NF-PNETs. METHODS A systematic search was performed up to March 2016 in MEDLINE, EMBASE and the Cochrane Library according to the PRISMA guidelines. Data was pooled using the random-effects model. RESULTS Nine articles including 344 patients with sporadic and 64 patients with MEN1 related NF-PNET were selected. Tumor growth was observed in 22% and 52%, development of metastases were reported on 0% and 9%, and rate of secondary surgical resection was 12% and 25% in patients with sporadic or MEN1 related NF-PNETs, respectively. All metastases (1 distant, 4 nodal) were reported by a single study in patients with MEN1. Reason for secondary surgery was tumor growth in half of patients undergoing surgery. DISCUSSION Expectant management of small asymptomatic, sporadic, NF-PNETs could be a reasonable option in highly selected patients. However, the level of evidence is low and longer follow-up is needed to identify patients could benefit from upfront surgery instead of expectant treatment.

Abstract
BACKGROUND Introduced more than 20 years ago, laparoscopic pancreatic surgery (LAPS) has not reached a uniform acceptance among HPB surgeons. As a result, there is no consensus regarding its use in patients with pancreatic neoplasms. This study, organized by the European Association for Endoscopic Surgery (EAES), aimed to develop consensus statements and clinical recommendations on the application of LAPS in these patients. METHODS An international panel of experts was selected based on their clinical and scientific expertise in laparoscopic and open pancreatic surgery. Each panelist performed a critical appraisal of the literature and prepared evidence-based statements assessed by other panelists during Delphi process. The statements were further discussed during a one-day face-to-face meeting followed by the second round of Delphi. Modified statements were presented at the plenary session of the 24th International Congress of the EAES in Amsterdam and in a web-based survey. RESULTS LAPS included laparoscopic distal pancreatectomy (LDP), pancreatoduodenectomy (LPD), enucleation, central pancreatectomy, and ultrasound. In general, LAPS was found to be safe, especially in experienced hands, and also advantageous over an open approach in terms of intraoperative blood loss, postoperative recovery, and quality of life. Eighty-five percent or higher proportion of responders agreed with the majority (69.5%) of statements. However, the evidence is predominantly based on retrospective case-control studies and systematic reviews of these studies, clearly affected by selection bias. Furthermore, no randomized controlled trials (RCTs) have been published to date, although four RCTs are currently underway in Europe. CONCLUSIONS LAPS is currently in its development and exploration stages, as defined by the international IDEAL framework for surgical innovation. LDP is feasible and safe, performed in many centers, while LPD is limited to few centers. RCTs and registry studies are essential to proceed with the assessment of LAPS.

Abstract
BACKGROUND Pancreas surgery has developed into a fairly safe procedure in terms of mortality, but is still hampered by considerable morbidity. Among the most frequent and dreaded complications are the development of a post-operative pancreatic fistula (POPF). The prediction and prevention of POPF remains an area of debate with several questions yet to be firmly addressed with solid answers. METHODS A systematic review of systematic reviews/meta-analyses and randomized trials in the English literature (PubMed/MEDLINE, Cochrane library, EMBASE) covering January 2005 to December 2015 on risk factors and preventive strategies for POPF. RESULTS A total of 49 systematic reviews and meta-analyses over the past decade discussed patient, surgeon, pancreatic disease and intraoperative related factors of POPF. Non-modifiable factors (age, BMI, comorbidity) and pathology (histotype, gland texture, duct size) that indicates surgery are associated with POPF risk. Consideration of anastomotic technique and use of somatostatin-analogs may slightly modify the risk of fistula. Sealant products appear to have no effect. Perioperative bleeding and transfusion enhance risk, but is modifiable by focus on technique and training. Drains may not prevent fistulae, but may help in early detection. Early drain-amylase may aid in detection. Predictive scores lack uniform validation, but may have a role in patient information if reliable pre-operative risk factors can be obtained. CONCLUSIONS Development of POPF occurs through several demonstrated risk factors. Anastomotic technique and use of somatostatin-analogs may slightly decrease risk. Drains may aid in early detection of leaks, but do not prevent POPF.

Abstract
Background Either enucleation or more extended resection is performed to treat patients with pancreatic neuroendocrine tumor (pNET). Aim was to analyze the postoperative complications for each operation separately. Furthermore, independent risk factors for complications and incidence of pancreatic insufficiency were analyzed. Methods Retrospective all resected patients from two academic hospitals in The Netherlands between 1992 and 2013 were included. Postoperative complications were scored by both ISGPS and Clavien–Dindo criteria. Based on tumor location, operations were compared. Independent risk factors for overall complications were identified. During long-term follow-up, pancreatic insufficiency and recurrent disease were analyzed. Results Tumor enucleation was performed in 60/205 patients (29 %), pancreatoduodenectomy in 65/205 (31 %), distal pancreatectomy in 72/205 (35 %) and central pancreatectomy in 8/205 (4 %) patients. Overall complications after tumor enucleation of the pancreatic head and pancreatoduodenectomy were comparable, 24/35 (69 %) versus 52/65 (80 %). The same was found after tumor enucleation and resection of the pancreatic tail (36 vs.58 %). Number of re-interventions and readmissions were comparable between all operations. After pancreatoduodenectomy, 33/65 patients had lymph node metastasis and in patients with tumor size ≤2 cm, 55 % had lymph node metastasis. Tumor in the head and BMI ≥25 kg/m2 were independent risk factors for complications after enucleation. During follow-up, incidence of exocrine and endocrine insufficiency was significant higher after pancreatoduodenectomy (resp. 55 and 19 %) compared to the tumor enucleation and distal pancreatectomy(resp. 5 and 7 % vs.8 and 13 %). After tumor enucleation 19 % developed recurrent disease. Conclusion Since the complication rate, need for re-interventions and readmissions were comparable for all resections, tumor enucleation may be regarded as high risk. Appropriate operation should be based on tumor size, location, and functional status of the pNET.

Abstract
BACKGROUND Previous studies report successful application of laparoscopic pancreatic enucleation (LPE). However, the evidence is limited to small series. This study aimed to evaluate the indications, technique and outcome of LPE at a tertiary care institution. METHODS Between February 1998 and April 2016, 45 consecutive LPEs were performed at Oslo University Hospital-Rikshospitalet. Twenty-four (53.3 %) patients subjected to right-sided LPE (RLPE) were compared with 21 (46.7 %) patients who had undergone left-sided LPE (LLPE). A case-matched analysis (1:2) was performed to compare the outcomes following LLPE and laparoscopic distal pancreatectomy (LDP). RESULTS Patient demographics, BMI, ASA score and pathological characteristics were similar between the RLPE and LLPE groups. Operative time was slightly longer for RLPE [123 (53-320) vs 102 (50-373) min, P = 0.09]. The rates of severe morbidity (≥Accordion grade III) and clinically relevant pancreatic fistula (grades B/C) were comparable, although with a trend for higher rate of complications following LLPE (16.7 vs 33.3 %; P = 0.19 and 20.8 vs 33.3 %, P = 0.34, respectively). The hospital stay was similar between RLPE and LLPE [5 (2-80) vs 7 (2-52), P = 0.49]. A case-matched analysis demonstrated shorter operating time [145 (90-350) vs 103 (50-233) min, P = 0.02], but higher readmission rate following LLPE (25 vs 3.1 %, P = 0.037). CONCLUSION LLPE seems to be associated with a higher risk of postoperative morbidity and readmission rates than LDP. RLPE is a feasible, safe approach and a reasonable alternative to pancreatoduodenectomy in selected patients with pancreatic lesions.

Abstract
PURPOSE Pancreatic neoplasms are uncommon in children. This study sought to analyze the clinical and pathological features of surgically resected pancreatic tumors in children and discuss management strategies. METHODS We conducted a retrospective review of patients ≤21 years with pancreatic neoplasms who underwent surgery at a single institution between 1995 and 2015. RESULTS Nineteen patients were identified with a median age at operation of 16.6 years (IQR 13.5-18.9). The most common histology was solid pseudopapillary neoplasm (SPN) (n = 13), followed by pancreatic neuroendocrine tumor (n = 3), serous cystadenoma (n = 2) and pancreatoblastoma (n = 1). Operative procedures included formal pancreatectomy (n = 17), enucleation (n = 1) and central pancreatectomy (n = 1). SPNs were noninvasive in all but one case with perineural, vascular and lymph node involvement. Seventeen patients (89.5 %) are currently alive and disease free at a median follow-up of 5.7 (IQR 3.7-10.9) years. Two patients died: one with metastatic insulinoma and another with SPN who developed peritoneal carcinomatosis secondary to a concurrent rectal adenocarcinoma. CONCLUSIONS Pediatric pancreatic tumors are a heterogeneous group of neoplastic lesions for which surgery can be curative. SPN is the most common histology, is characterized by low malignant potential and in selected cases can be safely and effectively treated with a tissue-sparing resection and minimally invasive approach.

Short- and long-term outcomes after enucleation of pancreatic tumors: An evidence-based assessment. Pancreatology 2016; 16:1092-1098. [PMID: 27423534 DOI: 10.1016/j.pan.2016.07.006] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2016] [Accepted: 07/06/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND OBJECTIVE Enucleation of pancreatic tumors is rarely performed. The aim of this study was to evaluate the published evidence for its short- and long-term outcomes. METHODS PubMed (MEDLINE) and EMBASE databases were searched from 1990 to March 2016. Studies including at least ten patients who underwent enucleation of pancreatic lesions were included. Data on the outcomes were synthesized and meta-analyzed where appropriate. RESULTS Twenty-seven studies involving 1316 patients were included in the systematic review. The postoperative mortality was 0.3%, and the postoperative morbidity was 50.3%, mainly represented by pancreatic fistula (38.1%). Endocrine insufficiency, exocrine insufficiency and tumor recurrence was observed in 2.4%, 1.1% and 2.3% of the patients respectively. Compared with typical resection, the operation time, blood loss, length of hospital stay, and the incidence of endocrine and exocrine insufficiency were all significantly reduced after enucleation. The occurrence of pancreatic fistula was significantly higher in enucleation group, but overall morbidity, the reoperation rate and mortality were comparable between the two groups. There was no significant difference in disease recurrence between the two groups. Compared with central pancreatectomy, enucleation had a shorter operation time, lower blood loss, less morbidity, and better pancreatic function. Compared with open enucleation, minimally invasive enucleation had a shorter operation time and a shorter length of hospital stay. CONCLUSIONS Enucleation is an appropriate surgical procedure in selected patients with benign or low-malignant lesions of the pancreas. The benefits of minimally invasive approach need to be validated in further investigations with larger groups of patients.

Abstract
Contrary to many other gastrointestinal operations, minimal access approaches in pancreatic surgery have gained ground slowly. Laparoscopic distal pancreatectomy has gained wide acceptance. It is associated with reduced blood loss and shorter duration of stay (DOS) while oncologic results and morbidity are similar to open surgery. In recent years the number of laparoscopic pancreatoduodenectomies has also increased. While oncological outcome seems comparable to the open approach, operative times are longer while DOS and blood loss are reduced. One added advantage of the laparoscopic approach to pancreatic cancer seems to be that adjuvant treatment can start earlier. Minimal access total pancreatectomy, only reported in small numbers (mostly robot assisted), has also been shown to be feasible and safe. Enucleation (EN) of small pancreatic lesions is the most common tissue sparing resection. Although no reconstruction is necessary, the risk of pancreatic fistula is high, related to excision margins equal or smaller than 2 mm to the main pancreatic duct. Compared to the open approach, laparoscopic EN has shown comparable results in terms of morbidity, pancreatic function and fistula rate, with shorter operation times and faster recovery. Experience in robot assisted pancreatic surgery is increasing. However reports are still small in numbers, lacking randomization and mostly limited to dedicated centers. The learning curve for minimal access pancreatic surgery is steep. Low patient volume leads to longer DOS, higher costs and negatively impacts outcome.

Abstract
Studies on postoperative complications and survival in patients with pancreatic neuroendocrine tumors (pNET) are sparse and randomized controlled trials are not available. We reviewed all studies on postoperative complications and survival after resection of pNET. A systematic search was performed in the Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE from 2000-2013. Inclusion criteria were studies of resected pNET, which described postoperative complications separately for each surgical procedure and/or 5-year survival after resection. Prospective and retrospective studies were pooled separately and overall pooled if heterogeneity was below 75%. The random-effect model was used. Overall, 2643 studies were identified and after full-text analysis 62 studies were included. Pancreatic fistula (PF) rate of the prospective studies after tumor enucleation was 45%; PF-rates after distal pancreatectomy, pancreatoduodenectomy, or central pancreatectomy were, respectively, 14-14-58%. Delayed gastric emptying rates were, respectively, 5-5-18-16%. Postoperative hemorrhage rates were, respectively, 6-1-7-4%. In-hospital mortality rates were, respectively, 3-4-6-4%. The 5-year overall survival (OS) and disease-specific survival (DSS) of resected pNET without synchronous resected liver metastases were, respectively, 85-93%. Heterogeneity between included studies on 5-year OS in patients with synchronous resected liver metastases was too high to pool all studies. The 5-year DSS in patients with liver metastases was 80%. Morbidity after pancreatic resection for pNET was mainly caused by PF. Liver resection in patients with liver metastases seems to have a positive effect on DSS. To reduce heterogeneity, ISGPS criteria and uniform patient groups should be used in the analysis of postoperative outcome and survival.

Abstract
BACKGROUND Standard pancreatectomy for benign and borderline pancreatic lesions involves resecting a substantial amount of normal pancreatic parenchyma and leads to a subsequent impairment of both exocrine and endocrine pancreatic functions. A limited resection such as enucleation is the preferred option for such neoplasms. However, enucleation is associated with a high risk of postoperative complications in some cases. This study evaluated the feasibility and outcomes of performing deep enucleation with Roux-en-Y pancreaticojejunostomy reconstruction. METHODS This study included patients who underwent pancreatic lesion enucleation from February 2010 to April 2014 in our hospital. The clinical data were collected and retrospectively analyzed. RESULTS This study examined 53 patients who underwent enucleation, 33 of the procedures included deep enucleation with Roux-en-Y pancreaticojejunostomy reconstruction. There was no mortality, and the morbidity rate was 66.7% in this group. No patients developed grade C pancreatic fistulas in both group. None of the patients developed tumor recurrence or exocrine or endocrine insufficiency at a median follow-up of 25 months. DISCUSSION Enucleation with Roux-en-Y pancreaticojejunostomy reconstruction is a safe and feasible procedure for the treatment of benign and borderline pancreatic neoplasms adjacent to the common pancreatic duct. This procedure can effectively mitigate the limitations of simple enucleation.

Abstract
BACKGROUND Postoperative pancreatic fistula remains the most severe and worrisome complication after surgery. Predictive preoperative assessment remains challenging. The authors examine the role of pancreatic computed tomography density in predicting postoperative pancreatic fistula after surgery for pancreatic neuroendocrine tumors. METHODS A single institutional retrospective review of pancreatic surgery for neuroendocrine tumors between 1998 and 2010 was conducted. Preoperative contrast-enhanced computed tomography scans were reviewed, with mean region of interest measurements of pancreatic parenchymal density obtained from 10-mm thick axial computed tomography images. RESULTS A total of 119 patients were identified: 59 with enucleations and 60 with resections. Decreased preoperative pancreatic density was significantly associated with an increased grade of postoperative pancreatic fistula (P < .01). Subgroup analyses revealed that decreased gland density was associated with increased grade of postoperative pancreatic fistula in the resection (P < .01) but not in the enucleation group (P = .34). CONCLUSIONS A significant association between postoperative pancreatic fistula grade and preoperative pancreatic computed tomography density is observed in patients undergoing resection for pancreatic neuroendocrine tumors.

Abstract
BACKGROUND Limited surgical procedures for benign cystic neoplasms and endocrine tumours of the pancreas have the potential advantage of pancreatic tissue sparing compared to standard oncological resections. METHODS Searching PubMed/MedLine, Embase and Cochrane Library identified 86 full papers: 25 reporting on enucleation (EN), 38 on central pancreatectomy (CP) and 23 on duodenum-preserving total/partial pancreatic head resection (DPPHRt/p). The results are based on analysis of data of 838, 912 and 431 patients for EN, CP and DPPHRt/s, respectively. RESULTS The indication for EN for cystic neoplasms and neuro-endocrine tumours to EN was 20.5 and 73 %; for CP 62.9 and 31 %; and for DPPHRt/p 69.6 and 10.2%, respectively. The estimated mean tumour sizes were in EN-group 2.4 cm, in CP-group 2.9 cm and in DPPHRt/p-group 3.1 cm (DPPHRt/p vs EN, p = 0.035). Postoperative severe complications developed after EN, CP and DPPHRt/p in 9.6, 16.8 and 11.5% of patients; pancreatic fistula in 36.7, 35.2 and 20.1%; and reoperation was required in 4.7, 6.5 and 1.8 %, respectively. Hospital mortality after EN was 0.95 %; after CP 0.72%; and after DPPHRt/p 0.49%. Compared to EN and CP, DPPHRt/p exhibited significant lower frequency of reoperation (p = 0.029, p < 0.001) and lower rate of fistula (p < 0.001; p = 0.001). CONCLUSION EN, CP and DPPHRt/p applied for benign tumours are associated with low surgery-related early postoperative morbidity, a very low hospital mortality and the advantages of conservation of pancreatic functions. However, the level of evidence for EN and CP compared to standard oncological resections appears presently low. There is a high level of evidence from prospective controlled trials regarding the significant maintenance of exocrine and endocrine pancreatic functions after DPPHRt/p compared to pancreato-duodenectomy.

Abstract
BACKGROUND Nonfunctioning pancreatic neuroendocrine tumors (NF-PNETs) are often discovered at a small size. No clear consensus exists on the management of NF-PNETs ≤ 2 cm. The aim of our study was to determine the prognostic value of indicators of malignancy in sporadic NF-PNETs ≤ 2 cm. METHODS Eighty patients were evaluated retrospectively in 7 French University Hospital Centers. Patients were managed by operative resection (operative group [OG]) or observational follow-up (non-OG [NOG]). Pathologic characteristics and outcomes were analyzed. RESULTS Sixty-six patients (58% women) were in the OG (mean age, 59 years; 95% CI, 56.0-62.3; mean tumor size, 1.6 cm; 95% CI, 1.5-1.7); 14 (72% women, n = 10) were in the NOG (mean age, 63 years; 95% CI, 56-70; mean tumor size, 1.4 cm; 95% CI, 1.0-1.7). All PNETs were ranked using the European Neuroendocrine Tumor Society grading system. Fifteen patients (19%) had malignant tumors defined by node or liver metastasis (synchronous or metachronous). The median disease-free survival was different between malignant and nonmalignant PNETs, respectively: 16 (range, 4-72) versus 30 months (range, 1-156; P = .03). On a receiver operating characteristic (ROC) curve, tumor size had a significant impact on malignancy (area under the curve [AUC], 0.75; P = .03), but not Ki-67 (AUC, 0.59; P = .31). A tumor size cutoff was found on the ROC curve at 1.7 cm (odd ratio, 10.8; 95% CI; 2.2-53.2; P = .003) with a sensitivity of 92% and a specificity of 75% to predict malignancy. CONCLUSION Based on our retrospective study, the cutoff of 2 cm of malignancy used for small NF-PNETs could be decreased to 1.7 cm to select patients more accurately.

Abstract
PURPOSE To evaluate the diagnostic performance of multiparametric pancreatic magnetic resonance (MR) imaging, including the T2*-corrected Dixon technique and intravoxel incoherent motion (IVIM) diffusion-weighted (DW) imaging, in the quantification of pancreatic steatosis and fibrosis, with histologic analysis as the reference standard, and to determine the relationship between MR parameters and postoperative pancreatic fistula. MATERIALS AND METHODS This retrospective study was approved by the institutional review board, and the informed consent requirement was waived. A total of 165 patients (93 men, 72 women; mean age, 62 years) underwent preoperative 3-T MR imaging and subsequent pancreatectomy (interval, 0-77 days). Fat fractions, IVIM DW imaging parameters (true diffusion coefficient [D], pseudodiffusion coefficient [D*], and perfusion fraction [f]), pancreas-to-muscle signal intensity ratios on unenhanced T1-weighted images, and pancreatic duct sizes were compared with the fat fractions and fibrosis degrees (F0-F3) of specimens. In 95 patients who underwent pancreatoenteric anastomosis, MR parameters were compared between groups with clinically relevant postoperative pancreatic fistula and those without. The relationship between postoperative pancreatic fistula and MR parameters was evaluated by using logistic regression analysis. RESULTS Fat fractions at MR imaging showed a moderate relationship with histologic findings (r = 0.71; 95% confidence interval: 0.63, 0.78). Patients with advanced fibrosis (F2-F3) had lower D*([39.72 ± 13.64] ×10(-3)mm(2)/sec vs [32.50 ± 13.09] ×10(-3)mm(2)/sec [mean ± standard deviation], P = .004), f (29.77% ± 8.51 vs 20.82% ± 8.66, P < .001), and unenhanced T1-weighted signal intensity ratio (1.43 ± 0.26 vs 1.21 ± 0.30, P < .001) than did patients with F0-F1 disease. Clinically relevant fistula developed in 14 (15%) of 95 patients, and f was significantly associated with postoperative pancreatic fistula (odds ratio, 1.17; 95% confidence interval: 1.05, 1.30). CONCLUSION Multiparametric MR imaging of the pancreas, including imaging with the T2*-corrected Dixon technique and IVIM DW imaging, may yield quantitative information regarding pancreatic steatosis and fibrosis, and f was shown to be significantly associated with postoperative pancreatic fistulas.

Postoperative sepsis in cancer patients undergoing major elective digestive surgery is associated with increased long-term mortality. J Crit Care 2015; 31:48-53. [PMID: 26507291 DOI: 10.1016/j.jcrc.2015.10.001] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2015] [Revised: 08/26/2015] [Accepted: 10/01/2015] [Indexed: 01/28/2023]
Abstract
BACKGROUND Major postoperative events (acute respiratory failure, sepsis, and surgical complications) are frequent early after elective gastroesophageal and pancreatic surgery. It is unclear whether these complications impact equally on long-term outcome. METHODS Prospective observational study including the patients admitted to the surgical intensive care unit between January 2009 and October 2011 after elective gastroesophageal and pancreatic surgery. Risk factors for 30-day major postoperative events and long-term outcome were evaluated. RESULTS During the study period, 259 patients were consecutively included. Among them, 166 (64%), 54 (21%), and 39 (15%) patients underwent pancreatic surgery, gastric surgery, and esophageal surgery, respectively. Using the Clavien-Dindo classification, 117 patients (45%) developed at least 1 postoperative complication, including 60 (23%) patients with acute respiratory failure, 77 (30%) with sepsis, and 89 (34%) with surgical complications. The median follow-up from the time of intensive care unit admission was 34 months (95% confidence interval, 30-37 months). The 1-year survival was 95% (95% confidence interval, 92-98). Among the perioperative variables, postoperative sepsis and an American Society of Anesthesiologists score higher than 2 were independently associated with long-term mortality. In septic patients, death (n = 16) was significantly associated with cancer recurrence (n = 10; P < .0001). Independent factors associated with postoperative sepsis were a Sequential Organ Failure Assessment score on day 1, a systemic inflammatory response syndrome on day 3, positive intraoperative microbiological samples, Simplified Acute Physiology Score II and an American Society of Anesthesiologists score higher than 2 (P < .005). CONCLUSIONS Postoperative sepsis was the only major postoperative event associated with long-term mortality. Postoperative sepsis may reflect a deep impairment of immune response, which is potentially associated with cancer recurrence and mortality.

Abstract
BACKGROUND The appropriate surgical strategy in patients with small pancreatic lesions of low malignant potential, such as pancreatic neuroendocrine tumors, remains unknown. Increasing reports suggest limited pancreatic surgery may be a safe option for parenchymal preservation. METHODS PubMed and MEDLINE were searched in the English literature for studies from January 2000 to February 2015 examining enucleation for pancreatic lesions that were single-arm and comparative studies (versus resection). Single-arm enucleation studies were systematically reviewed. Comparative studies were included for meta-analysis. Endpoints include safety, complications, mortality, survival, and parenchymal-related outcomes. RESULTS Thirteen studies comprising of 1101 patients undergoing enucleation were included. Seven studies were comparative studies of enucleation and standardized pancreatic resection. Enucleation was a shorter procedure (pooled mean differences (MD) = 109, 95 % confidence interval (CI) 105-114; Z = 46.37; P < 0.001) associated with less blood loss (pooled MD = 314, 95 % CI 297-330; Z = 37.47; P < 0.001). Both enucleation and resection had similar mortality and complication rates, but the rate of pancreatic fistula (all grades) (pooled odds ratio (OR) = 1.99; 95 % CI 1.2-3.4; Z = 2.57; P = 0.01] and rate of pancreatic fistula (grade B/C) (pooled OR = 1.58; 95 % CI 1.0-2.5; Z = 2.06; P = 0.04) was higher in the enucleation group. Enucleation resulted in lower rates of endocrine (pooled OR = 0.22; 95 % CI 0.1-0.5; Z = 3.21; P = 0.001) and exocrine (pooled OR = 0.07; 95 % CI 0.02-0.2; Z = 5.08; P < 0.001) insufficiency. The median 5-year survival was 95 % (range 93-98) and 84 % (range 79-90). CONCLUSIONS Enucleation appears to be a safe procedure and achieves parenchymal preservation for small pancreatic lesions of low malignant potential. Its oncologic efficacy compared with standardized pancreatic resection with respect to long-term survival and recurrences have not been reported adequately and hence may not be concluded as being comparable.

Abstract
Parenchyma-sparing pancreatectomy, including enucleation and central pancreatectomy, has been investigated as an alternative to standard resection (pancreaticoduodenectomy or left/distal pancreatectomy) for pancreatic neuroendocrine tumor (PNET). In selected patients, with small (<2 cm) and low-grade tumors, PSP are associated with excellent both overall and disease-free survivals. These procedures are associated with an increased postoperative morbidity but an excellent long-term postoperative pancreatic function. Therefore, they should be considered as a valid therapeutic option in selected well-differentiated PNET.
