Abstract
BACKGROUND Pancreatoduodenectomy (PD) has a considerable surgical risk for complications and late metabolic morbidity. Parenchyma-sparing resection of benign tumors has the potential to cure patients associated with reduced procedure-related short- and long-term complications. MATERIALS AND METHODS Pubmed, Embase, and Cochrane libraries were searched for studies reporting surgery-related complications following PD and duodenum-preserving total (DPPHRt) or partial (DPPHRp) pancreatic head resection for benign tumors. A total of 38 cohort studies that included data from 1262 patients were analyzed. In total, 729 patients underwent DPPHR and 533 PD. RESULTS Concordance between preoperative diagnosis of benign tumors and final histopathology was 90.57% for DPPHR. Cystic and neuroendocrine neoplasms (PNETs) and periampullary tumors (PATs) were observed in 497, 89, and 31 patients, respectively. In total, 34 of 161 (21.1%) patients with intraepithelial papillar mucinous neoplasm exhibited severe dysplasia in the final histopathology. The meta-analysis, when comparing DPPHRt and PD, revealed in-hospital mortality of 1/362 (0.26%) and 8/547 (1.46%) patients, respectively [OR 0.48 (95% CI 0.15-1.58); p = 0.21], and frequency of reoperation of 3.26 % and 6.75%, respectively [OR 0.52 (95% CI 0.28-0.96); p = 0.04]. After a follow-up of 45.8 ± 26.6 months, 14/340 patients with intraductal papillary mucinous neoplasms/mucinous cystic neoplasms (IPMN/MCN, 4.11%) and 2/89 patients with PNET (2.24%) exhibited tumor recurrence. Local recurrence at the resection margin and reoccurrence of tumor growth in the remnant pancreas was comparable after DPPHR or PD [OR 0.94 (95% CI 0.178-5.34); p = 0.96]. CONCLUSIONS DPPHR for benign, premalignant neoplasms provides a cure for patients with low risk of tumor recurrence and significantly fewer early surgery-related complications compared with PD. DPPHR has the potential to replace PD for benign, premalignant cystic and neuroendocrine neoplasms.

Abstract
BACKGROUND Pancreatic benign, cystic, and neuroendocrine neoplasms are increasingly detected and recommended for surgical treatment. In multiorgan resection pancreatoduodenectomy or parenchyma-sparing, local extirpation is a challenge for decision-making regarding surgery-related early and late postoperative morbidity. METHODS PubMed, Embase, and Cochrane Libraries were searched for studies reporting early surgery-related complications following pancreatoduodenectomy (PD) and duodenum-preserving total (DPPHRt) or partial (DPPHRp) pancreatic head resection for benign tumors. Thirty-four cohort studies comprising data from 1099 patients were analyzed. In total, 654 patients underwent DPPHR and 445 patients PD for benign tumors. This review and meta-analysis does not need ethical approval. RESULTS Comparing DPPHRt and PD, the need for blood transfusion (OR 0.20, 95% CI 0.10-0.41, p<0.01), re-intervention for serious surgery-related complications (OR 0.48, 95% CI 0.31-0.73, p<0.001), and re-operation for severe complications (OR 0.50, 95% CI 0.26-0.95, p=0.04) were significantly less frequent following DPPHRt. Pancreatic fistula B+C (19.0 to 15.3%, p=0.99) and biliary fistula (6.3 to 4.3%; p=0.33) were in the same range following PD and DPPHRt. In-hospital mortality after DPPHRt was one of 350 patients (0.28%) and after PD eight of 445 patients (1.79%) (OR 0.32, 95% CI 0.10-1.09, p=0.07). Following DPPHRp, there was no mortality among the 192 patients. CONCLUSION DPPHR for benign pancreatic tumors is associated with significantly fewer surgery-related, serious, and severe postoperative complications and lower in-hospital mortality compared to PD. Tailored use of DPPHRt or DPPHRp contributes to a reduction of surgery-related complications. DPPHR has the potential to replace PD for benign tumors and premalignant cystic and neuroendocrine neoplasms of the pancreatic head.

Abstract
Historically, the management of pancreatic cystic neoplasms (PCN) has been operative. Early intervention for premalignant lesions, including intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms (MCN), offers an opportunity to prevent pancreatic cancer-with potential decrement to patients' short-term and long-term health. The operations performed have remained fundamentally the same, with most patients undergoing pancreatoduodenectomy or distal pancreatectomy using oncologic principles. The role of parenchymal-sparing resection and total pancreatectomy remains controversial. We review innovations in the surgical management of PCN, focusing on the evolution of evidence-based guidelines, short-term and long-term outcomes, and individualized risk-benefit assessment.

Abstract
BACKGROUND/AIMS A tissue diagnosis is not always obtained prior to pancreatoduodenectomy (PD) and a proportion of patients are found to have noncancerous histology postoperatively. It is unknown if these patients have different outcomes when compared with those who have malignancy confirmed. METHODS A retrospective paired case matched control study was undertaken. Patients who underwent PD for suspected malignancy but ultimately had nonmalignant histology were identified. Each was matched to a confirmed malignant control using the following criteria: age, gender, body mass index, American Society of Anesthesiologists grade, neoadjuvant treatment, preoperative serum bilirubin, preoperative biliary stenting and type of pancreatic anastomosis. Matching was blinded to the measured outcomes, which included perioperative morbidity and mortality. RESULTS Forty-five cases were compared with 45 well-matched controls. There was no difference in 30- or 90-day mortality, or length of stay. While overall morbidity rates were the same, patients with nonmalignant disease were more likely to experience major (Clavien-Dindo grade III-IV) morbidity (40.0% versus 17.8%, p = 0.0352). Independently, rates of clinically relevant pancreatic fistula (CR-POPF) were higher in the nonmalignant group (22.2% versus 4.44%, p = 0.0131). CONCLUSIONS In our study, PD patients with nonmalignant histology had significantly higher incidence of major morbidity and CR-POPF when compared with those who had malignancy confirmed. This should be considered when planning the management of patients with known or presumed benign/premalignant disease.

Abstract
The extent of surgical resection in the treatment of pancreatic neuroendocrine neoplasms (pNEN) is still controversial. This study aimed to evaluate the outcomes of enucleation for well-differentiated non-functional (nf) pNEN. Patients undergoing enucleation (2001−2020) were analyzed. Clinicopathological parameters, perioperative outcomes and survival were assessed. The analysis was performed as a nested case-control study and matched-pair analysis with formal resection. Sixty-one patients undergoing enucleation were identified. Compared to patients undergoing formal resection, enucleation was associated with a significantly shorter median length of operative time (128 (IQR 95−170) versus 263 (172−337) minutes, p < 0.0001) and a significantly lower rate of postoperative diabetes (2% versus 21%, p = 0.0020). There was no significant difference in postoperative pancreatic fistula rate (18% versus 16% type B/C, p = 1.0), Clavien−Dindo ≥ III complications (20% versus 26%, p = 0.5189), readmission rate (12% versus 15%, p = 0.6022) or length of hospital stay (8 (7−11) versus 10 (8−17) days, p = 0.0652). There was no 30-day mortality after enucleation compared to 1.6% (n = 1) after formal resection. 10-year overall survival (OS) and disease-free survival (DFS) was similar between the two groups (OS: 89% versus 77%, p = 0.2756; DFS: 98% versus 91%, p = 0.0873). Enucleation presents a safe surgical approach for well-differentiated nf-pNEN with good long-term outcomes for selected patients.

Abstract
Pancreatic neuroendocrine neoplasms (pNEN) have a rising incidence and are increasingly diagnosed at early and thus potentially resectable stages. Due to the rarity of these neoplasms the recommendations of currently available guidelines are mainly based on retrospective data. Surgical and oncological treatment of these rare diseases should only be performed at specialized centers. In cases of resectability without indications of diffuse metastases, complete resection with curative intent should be the treatment of choice. For small nonfunctional pNENs < 2 cm watch and wait strategies are recommended as an alternative to surgical treatment. Recent data, however, also showed an increased survival even of small (1-2 cm) pNENs after resection. For benign insulinomas and small nonfunctional well-differentiated pNENs parenchyma-sparing procedures, such as enucleation and segmental resection are available. The question of the influence of lymph node metastases on long-term disease-free survival and overall survival and consequently the role of systematic lymphadenectomy is still a matter of debate. In pNENs > 2 cm formal resection with lymphadenectomy is considered the gold standard. Minimally invasive and robotic-assisted procedures are of increasing importance also for formal pancreatic resection.

Abstract
ZusammenfassungLaut aktuellen revidierten Fukuoka-Leitlinien besteht die Indikation zur Resektion von BD-IPMN des Pankreas mit Worrisome Features, da hier ein Risiko der malignen Entartung von bis zu 30%
besteht. Die Resektion kann bei fehlenden klinischen, bildmorphologischen und laborchemischen Malignitätszeichen als eine nicht anatomische, lokale Exzision durchgeführt werden.Eine robotische Enukleation bei benignen Raumforderungen der Bauchspeicheldrüse stellt eine sehr gute Alternative zu den resezierenden Verfahren, insbesondere zu denjenigen in offener
Technik, dar. Diese operative Behandlungsoption wird bei einem Mindestabstand bis zum pankreatischen Hauptgang von mindestens 2 mm im „International consensus statement on robotic pancreatic
surgery“ nahegelegt.Neben den bekannten Vorteilen der minimalinvasiven Chirurgie führt diese parenchymsparende Methode zum Erhalt von endo- und exokriner Funktion (ca. 90%) und zu einem progressfreien
10-Jahres-Überleben von ca. 75% bei etwas erhöhter Morbidität (ca. 60%) verglichen mit den resezierenden Verfahren.Der folgende Videobeitrag präsentiert das Operationsvideo einer robotischen Zystenenukleation (bei Verdacht auf eine BD-IPMN mit Worrisome Features) im Pankreaskopf und Processus uncinatus
bei einer 62-jährigen Patientin mit besonderer Betonung der wichtigsten vaskulären Landmarken, Besonderheiten der Herangehensweise und Vorteile der robotischen Technik.

Abstract
Objective To evaluate the relationship between pancreatic parenchyma loss and early postoperative hyperglycemia in patients with benign pancreatic diseases. Methods A total of 171 patients with benign pancreatic tumors or chronic pancreatitis, whose preoperative fasting blood glucose (FBG) was normal and who underwent partial pancreatectomy were reviewed. The pancreatic volume was measured by CT imaging before and after the operation. According to their different pancreatic resection volume (PRV), 171 patients were divided into five groups: < 30%, 30%–39%, 40%–49%, 50%–59%, and ≥ 60%. The correlation between the PRV and postoperative FBG was investigated. According to the postoperative FBG value, the patients were divided into a hyperglycemia group (HG) and nonhyperglycemia group (non-HG) to explore the best cutoff value of the PRV between the two groups. Results There were significant differences in the postoperative FBG among the five groups (PRV < 30%, 30%–39%, 40%–49%, 50%–59%, and ≥ 60%). The PRV was positively correlated with postoperative FBG in the benign tumor group and chronic pancreatitis group (R = 0.727 and 0.651, respectively). ROC curve analysis showed that the best cutoff value of the PRV between the HG (n = 84) and non-HG (n = 87) was 39.95% with an AUC = 0.898; the sensitivity was 89.29%, and the specificity was 82.76%. Conclusion There was a linear positive correlation between the postoperative FBG level and PRV. Patients with a PRV ≥ 40% are more likely to develop early postoperative hyperglycemia.

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.

Abstract
Parenchymal sparing duodenal and pancreatic resection are safe procedures in selected patients with the aim to reduce endocrine and exocrine long-term dysfunction. When the tumor is benign or borderline malignant, this appears to be a good option for the surgeon, associated with low rates of severe surgery-related early postoperative complications and low in-hospital mortality. This mini review offers comments, tips and tricks, and a review of literature concerning those different options with specific illustrations in order to clarify their indication.

Abstract
BACKGROUND Laparoscopic enucleation of pancreatic tumours is seemingly a simple procedure, but challenging as the tumour is deeply embedded in the pancreatic parenchyma. Our study reports a single-centre experience for these cases. METHODS Cases with a tumour underwent laparoscopic enucleation from January 2014 to March 2020 in our hospital were collected and analysed. RESULTS Sixty-six cases were enrolled, including 21 men and 45 women with an average age of 43.6 ± 16.7 years old. The mean size of tumours was 2.7 ± 1.8 cm. The tumours were mainly located at the pancreatic head and neck (63.6%). The most common pathological diagnoses were insulinomas, followed by solid pseudopapillary tumours. Incidences of overall complications and pancreatic fistula (PF, Grade B) were 24.2% and 19.7%, respectively. No patient developed PF (Grade C) or died. Cases were divided into two groups according to whether the tumour was deeply embedded in the pancreas. Compared to the group with a superficial tumour (n = 36), the group with an embedded tumour (n = 30) had a longer operation time and drainage duration and a smaller tumour size (P < 0.05), but did not increase the incidence of complications and PF (Grade B/C). CONCLUSION Laparoscopic enucleation of tumours that were deeply embedded in the pancreas was technically feasible and safe.

Abstract
A 62-year-old man was referred to the Hepato-Pancreato-Biliary (HPB) surgeons with left upper quadrant discomfort. The initial investigations and CT scans revealed a tumour in the pancreatic tail with liver metastases, confirmed on MRI. It was initially thought to be an adenocarcinoma; however, further investigations found that it was a grade 1 neuroendocrine tumour with Ki 67 at 1% and it was agreed that he would undergo a total robotic surgery involving resection of the locally advanced tumour of the tail of pancreas, with the involvement of the stomach, and splenic flexure of the colon with liver metastases. The resulting procedure was a total robotic distal pancreatectomy, splenectomy, sleeve resection of stomach, cholecystectomy, atypical resection of two liver lesions and microwave ablation of multiple liver lesions. Four days post-operatively, he was discharged from hospital and commenced adjuvant chemotherapy. He currently enjoys a good quality of life.

Abstract
BACKGROUND Pancreatic neuroendocrine tumors (PNET) are rare, with a significant malignant potential. This study aimed to determine outcomes of patients with resected PNETs according to the cystic component and confirm the accuracy of preoperative staging. METHODS From 1997 to 2016, 106 patients underwent resection of PNETs, including 73 purely solid (S-PNETs, 69%), 21 mixed (M-PNETs, 20%), and 12 purely cystic lesions (C-PNETs, 11%). To ensure consistent comparisons of overall (OS) and disease-free (DFS) survival outcomes between the 3 groups, the patients were matched according to the World Health Organization (WHO) grade and tumor height. RESULTS Overall, the rate of correlation between the preoperative and pathological diagnoses was low in the C-PNET group (33%, P = 0.03). None of the 24 patients (23%) with metastatic disease at the time of surgery were in the C-PNET group. Furthermore, significantly more parenchyma-sparing resections (P = 0.039) and fewer enlarged resections (P = 0.019) were achieved in the C-PNET group. C-PNET group had a significantly lower node invasion rate than the S-PNET and M-PNET groups (8% vs. 41% and 24%, P = 0.004). Although median OS was comparable in all 3 groups before (P = 0.3) and after (P = 0.18) matching, higher median DFS was observed in the C-PNET group than in the other groups after matching (P = 0.038). CONCLUSION C-PNET was associated with a better prognosis than PNET with a solid component. The results support a wait-and-see policy in cases wherein a reliable preoperative diagnosis remains challenging.

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.

Abstract
Radical surgery represents the only curative treatment for pancreatic neuroendocrine neoplasms (PanNEN). The aim of this study was to evaluate the postoperative onset of diabetes mellitus (DM) and/or pancreatic exocrine insufficiency (PEI) in surgically treated PanNEN. Consecutive PanNEN patients, without preoperative DM, who underwent partial pancreatic resection, were included. After a median follow-up of 72 months, overall 68/276 patients (24%) developed DM. Patients who developed DM were significantly older (p = 0.002) and they had a higher body mass index (BMI) (p < 0.0001) than those who did not; they were more frequently male (p = 0.017) and with nonfunctioning neoplasms (p = 0.019). BMI > 25 Kg/m2 was the only independent predictor of DM (p = 0.001). Overall, 118/276 patients (43%) developed a PEI, which was significantly more frequent after pancreaticoduodenectomy (p < 0.0001) and in patients with T3-T4 tumors (p = 0.001). Pancreaticoduodenectomy was the only independent predictor of PEI (p < 0.0001). Overall, 54 patients (20%) developed disease progression. Patients with and without DM had similar progression free survival (PFS), whereas patients without PEI had better five-year-PFS (p = 0.002), although this association was not confirmed in multivariate analysis. The risk of DM and PEI after surgery for PanNEN is relatively high but it does not affect PFS. BMI and pancreatic head resection are independent predictors of DM and PEI, respectively.

Abstract
INTRODUCTION We report the case of a 77-year-old female patient with the diagnosis of pancreatic head insulinoma, in whom we used near infrared light (NIR) to detect synchronous pancreatic tumors and potential secondary lymph node or liver involvement. The patient presented with hypoglycemia manifesting by lipothymia. With the diagnosis of secretory neuroendocrine tumor (insulinoma) of the pancreatic head, cephalic pancreatoduodenectomy with the preservation of the pylorus was performed after NIR visualization of the pancreatic tumor mass. At 6, 12, 18 months postoperatively, the patient no longer had hypoglycemia and her general state was good. CONCLUSION NIR with indocyanine green (ICG) evidences pancreatic neuroendocrine tumors, as well as possible synchronous tumors and secondary lymph node or liver involvement.

Abstract
BACKGROUND Pancreatic enucleation (pEN) as parenchyma-sparing procedure for small pancreatic neoplasms is quickly becoming the most common surgical option in such setting. Nowadays, pEN is frequently carried out through a minimally invasive approach either laparoscopic or robotic. Its impact on overall perioperative complications and pancreatic fistula (POPF) is still under evaluation. The scope of our systematic review is to assess pEN's perioperative outcomes and to evaluate the effect of the minimally invasive techniques over POPF and other surgical complications. METHODS We performed a systematic literature search (time-frame January 1999-September 2018), considering exclusively those studies which included at least 5 cases of either open or minimally invasive pEN. Data regarding postoperative outcome and POPF were extracted and analyzed. We defined postoperative morbidities by the Clavien-Dindo classification while POPF according to the International Study Group of Pancreatic Fistula (ISGPF) definition. RESULTS Sixty-three studies met the criteria selected, accounting for a study population of 2485 patients. 27.7% had a minimally invasive pEN. The overall postoperative morbidity rate was 46.1% with 11.9% rated as severe (Clavien-Dindo ≥ 3). Mortality rate was 0.69%. The minimally invasive approach to pEN led to a statistically significant reduction of both the overall POPF rate (28.7% vs. 45.9%, p < 0.001), and clinically significant B-C POPF (p < 0.027). The postoperative overall morbidity rate was clearly in favor of the minimally invasive approach (27.6% vs. 55.2%, p < 0.001). CONCLUSIONS Our review confirms that pEN is a safe and feasible technique for the treatment of small benign or low-grade pancreatic neoplasms and it can be implemented with an acceptable morbidity rate along with low mortality. The minimally invasive approach is gaining widespread acceptance due to its supposed non-inferiority compared with the traditional open approach. In our review, it showed to be even better in terms of POPF incidence rate and short-term postoperative outcome. Still, such data need to be corroborated by randomized clinical trials.

Abstract
BACKGROUND Robotic surgery is the most advanced minimally invasive technique for the treatment of complicated solid pseudopapillary tumors (SPT). The aim of this study is to evaluate feasibility of robotic surgery for the treatment of SPTs in the pancreatic head. METHODS A retrospective analysis of the clinical data of 83 SPTs in pancreatic head was conducted. Clinical characteristics were extracted and propensity score matching (PSM) was used to compare and evaluate mid-term outcomes of the two techniques. RESULTS Pancreaticoduodenectomy (PD), duodenum-preserving partial pancreatic head resection (DPPHR-P) and tumor enucleation (En) were performed in 51, 24, and 8 patients, respectively. The robotic approach was associated with a significantly lower volume of blood loss, lower need for transfusion, and faster time to post-surgery recovery. Major complications and costs were comparable for both techniques. CONCLUSION A robotic approach provides an alternative to open surgery for SPTs in the pancreatic head without increasing the incidence of clinically relevant pancreatic fistula (CRPF) or other major complications and with good patient outcomes.

Abstract
AIM OF STUDY Duodenum-preserving resection of the pancreatic head (DPRPH) with Roux-en-Y pancreatojejunostomy is a procedure used to remove focal pathological lesions of the pancreatic head. Although predominantly used in adult patients, it is both safe and effective in children. The aim of this study was to review our experience with this procedure, with focus on its indications, complications and long-term outcomes. METHODS A retrospective analysis of pediatric patients who underwent DPRPH between 1994 and 2015 was performed. Patient files were reviewed for demographic, diagnostic, operative and histological details, postoperative complications. Patients were contacted telephonically and sent questionnaires to determine long-term outcomes. RESULTS The study cohort consists of 21 patients, 14 girls and 7 boys, with an average age of 11.72 years (range 3 months to 18.6 years), who underwent DPRPH with end-to-end anastomosis of the jejunum to the pancreatic body (Roux-en-Y anastomosis). In four cases the head and also part of the body of the pancreas was resected. In the remaining 17 cases, only the head of the pancreas was resected. Indications for DPRPH were solid pseudopapillary tumor of the pancreas (n = 10), trauma (n = 8), pancreas divisum (n = 1), focal congenital hyperinsulinism (n = 1) and pancreatic cyst (n = 1). The length of follow-up ranged from 1 to 22 years (average 9.66). One patient developed a biliary fistula, which closed spontaneously within 2 weeks after stent insertion. A recurrence of abdominal pain was reported in two patients, occurring at 7 months after the operation in one patient and at 1 year in the other. Pancreatic endocrine insufficiency did not occur in any of the 21 patients. Seven patients currently require a low fat diet, five of which need pancreatic enzyme supplementation. An additional two patients need enzyme supplementation without dietary restriction. CONCLUSION DPRPH is a safe and effective procedure for the treatment of large focal pathological lesions of the pancreatic head in children. As a less invasive procedure than pancreatoduodenectomy, it is more appropriate for the developing child.

Abstract
The management of patients with sporadic pancreatic neuroendocrine tumors (PNET) is multi-disciplinary and often, multimodal. Surgery has a large part in treatment because it is the only potentially curative therapeutic modality if resection can be complete. The update reviews the operative indications and the different surgical techniques available (including parenchymal-sparing surgery) to treat the primary lesion according to patient status, preoperative work-up and whether the tumor is functioning or not. The place of observation for "small" non-functional sporadic PNET is also discussed.

Robotic enucleations of pancreatic benign or low-grade malignant tumors: preliminary results and comparison with robotic demolitive resections. Surg Endosc 2018; 33:2834-2842. [PMID: 30421079 DOI: 10.1007/s00464-018-6576-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2018] [Accepted: 11/02/2018] [Indexed: 12/27/2022]
Abstract
BACKGROUND The incidental detection of benign to low-grade malignant small pancreatic neoplasms increased in the last decades. The surgical management of these patients is still under debate. The aim of this paper is to evaluate the safety and feasibility of robotic enucleations and to compare the outcomes with non-parenchymal sparing robotic resections. METHODS The study included a total of 25 patients. Nine of them underwent a robotic enucleation (EN Group) and 16 patients received a robotic demolitive resection (DR Group). Perioperative and medium-term outcomes were compared between the two groups. RESULTS Patients' baseline characteristics were similar in the two groups except for presence of symptoms and tumor size, due to the inclusion criteria. Operative time was significantly shorter and postoperative results were better for EN group, including a significant shorter hospitalization (5 vs. 8 days, p = 0.027), reduced pancreatic leaks (22% vs. 50%, p = 0.287) and a better preservation of glandular function (100% vs. 62.5%, p = 0.066). Mortality rate was zero in both groups, with all patients free from disease at a median follow-up of 18 months. CONCLUSIONS The risks of under/overtreatment remain still unavoidable for benign to low-grade malignant small pancreatic neoplasms. Simple enucleation should be performed whenever oncological appropriate, to achieve the best postoperative outcomes. The adoption of robotic technique might widen the indications for parenchymal sparing, minimally invasive surgery.

Abstract
BACKGROUND Parenchyma-sparing, local pancreatic head resection, but not pancreaticoduodenectomy (PD) preserves tissue and maintains the pancreatic metabolic functions. METHODS PubMed/Medline, Embase, and Cochrane library collections were systematically searched. Twenty-six cohort studies with 523 cumulative patients, who underwent duodenum-sparing pancreatic head resection (DPPHR), were retrieved. The meta-analysis was based on 14 controlled studies. RESULTS In total, 338 patients suffered cystic neoplasms and 59 PNETs, IPMN-174, MCN-43 and SPN-23 patients. Eighty-one patients (15.5%) histo-pathologically displayed a low-malignant tumor, of which 27 were carcinoma in-situ. Tumor recurrence was observed after a mean follow-up of 47.1 months in 11 patients. In-hospital and late mortality after DPPHR was 0.6% and 1.7%, respectively. The meta-analysis was based on 318 DPPHR compared to 404 PD patients. DPPHR was performed for premalignant neoplasm and PNET in 164 and 46 patients, and PD in 181 and 46 patients, respectively. Events of recurrence displayed no statistically significant difference between the DPPHR and PD groups. CONCLUSION DPPHR is associated with oncologically complete tumor resection for patients suffering premalignant IPMN, MCN, or SPN and for low-risk cancer.

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
BACKGROUND Pancreatic neuroendocrine tumors (PanNETs) are relatively rare neoplasms with a low to mild malignant potential. They can be further divided into functioning and nonfunctioning, according to their secretive activity. Surgery is an optimal approach, but the classic open approach is challenging, with some patients having long hospitalization and potentially life-threatening complications. The robotic approach for PanNETs may represent an option to optimize their management. METHODS We retrospectively reviewed our prospectively maintained databases from 2 high-volume Italian centers for pancreatic surgery. Demographics, pathological characteristics, perioperative outcome, and medium-term follow-up of patients who underwent robotic pancreatic enucleations were collected. RESULTS Twelve patients with final diagnosis of PanNET were included. The mean age of the patients was 53.8 years (25-77). The median body mass index was 26 (24-29). Three lesions were functioning insulinomas, while the others were nonfunctioning tumors. No deaths occurred. Mild postoperative complications occurred, except for 1 grade B pancreatic fistula. The mean postoperative stay was 3.9 days (2-5). CONCLUSIONS Our results confirm that robotic enucleation is a feasible and safe approach for the treatment of PanNETs, with short hospital stay and low incidence of morbidity.

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
Pancreaticoduodenectomy and left-sided pancreatectomy are the surgical treatment standards for tumors of the pancreas. Surgeons, who are requested to treat patients with benign tumors, using standard oncological resections, face the challenge of sacrificing pancreatic and extra-pancreatic tissue. Tumor enucleation, pancreatic middle segment resection and local, duodenum-preserving pancreatic head resections are surgical procedures increasingly used as alternative treatment modalities compared to classical pancreatic resections. Use of local resection procedures for cystic neoplasms and neuro-endocrine tumors of the pancreas (panNETs) is associated with an improvement of procedure-related morbidity, when compared to classical Whipple OP (PD) and left-sided pancreatectomy (LP). The procedure-related advantages are a 90-day mortality below 1% and a low level of POPF B+C rates. Most importantly, the long-term benefits of the use of local surgical procedures are the preservation of the endocrine and exocrine pancreatic functions. PD performed for benign tumors on preoperative normo-glycemic patients is followed by the postoperative development of new onset of diabetes mellitus (NODM) in 4 to 24% of patients, measured by fasting blood glucose and/or oral/intravenous glucose tolerance test, according to the criteria of the international consensus guidelines. Persistence of new diabetes mellitus during the long-term follow-up after PD for benign tumors is observed in 14.5% of cases and after surgery for malignant tumors in 15.5%. Pancreatic exocrine insufficiency after PD is found in the long-term follow-up for benign tumors in 25% and for malignant tumors in 49%. Following LP, 14-31% of patients experience postoperatively NODM; many of the patients subsequently change to insulin-dependent diabetes mellitus (IDDM). The decision-making for cystic neoplasms and panNETs of the pancreas should be guided by the low surgical risk and the preservation of pancreatic metabolic functions when undergoing a limited, local, tissue-sparing procedure.

Abstract
The management of patients with pancreatic neuroendocrine tumor (PNET), whether hormonally secretory or not, is multidisciplinary and often multimodal. Surgical treatment plays a central role because complete resection is the only potentially curative treatment. The choice of the therapeutic plan for a PNET requires precise localization of the primary tumor (which may sometimes be multiple in case of genetic predisposition), confirmation of the diagnosis of PNET, a search for metastases (mainly hepatic), and identification of the main histoprognostic factors. This update focuses on the WHO 2017 histological classification and recent innovations in the preoperative assessment of PNET using conventional and isotopic imaging. The aim is to not only allow the mapping of primary and metastatic lesions but also to predict tumor aggressiveness.

Abstract
BACKGROUND Enucleation is increasingly performed for benign or borderline tumours of the pancreas because it is a parenchyma-sparing and less invasive procedure compared to conventional pancreatectomy, which reduces the risk of exocrine and endocrine insufficiency. This study retrospectively evaluated and compared the pre-, intra-, and post-operative clinical characteristics after open and robotic approaches for pancreatic enucleation. METHODS Fifty-six cases of enucleation for benign or borderline tumours of the pancreas treated from March 2010 to July 2015 were identified by a retrospective search. These included 25 patients who underwent an open approach and 31 patients who underwent a robotic approach. The clinical characteristics were extracted and compared. RESULTS The two groups had a similar location and pathology of the tumour. The robotic group had a significantly shorter operation time and significantly less blood loss than the open group. The rates of clinical pancreatic fistula (PF) formation and major complications were similar. The robotic approach could be applied for a tumour on the right side of the pancreas without increasing the incidence of clinical PF or other major complications. The patients with clinical PF had a significantly shorter distance between the lesion and the main pancreatic duct (MPD). CONCLUSION Robotic enucleation appears to be a feasible and safe approach for benign or borderline tumours of the pancreas and was associated with similarly favourable surgical outcomes as the open approach. Identifying and avoiding the MPD is an important step during enucleation.

Abstract
Glucose is the main substrate utilized by the brain and as such multiple regulatory mechanisms exist to maintain glucose concentrations. When these mechanisms fail or are defective, hypoglycemia ensues. Due to these robust mechanisms, hypoglycemia is uncommon and usually occurs in the setting of the treatment of diabetes using glucose-lowering agents such as sulfonylureas or insulin. The symptoms of hypoglycemia are non-specific and as such it is important to confirm hypoglycemia by establishing the presence of Whipple's triad before embarking on an evaluation for hypoglycemia. When possible, evaluation of hypoglycemia should be carried out at the time of spontaneous occurrence of symptoms. If this is not possible then one would want to create the circumstances under which symptoms occur. In cases where symptoms occur in the post absorptive state, a 72-h fast should be performed. Likewise, if symptoms occur after a meal then a mixed meal study may be the test of choice. The causes of endogenous hyperinsulinemic hypoglycemia include insulinoma, post-bariatric hypoglycemia and noninsulinoma pancreatogenous hypoglycemia syndrome. Autoimmune hypoglycemia syndrome is clinically and biochemically similar to insulinoma but associated with high levels of insulin antibodies and plasma insulin. Other important causes of hypoglycemia include medications, non-islet cell tumors, hormonal deficiencies, critical illness and factitious hypoglycemia. We provide an overview of the pathogenesis and management of hypoglycemia in these situations.

Abstract
We present the case of a 45 year old female patient with an incidental diagnosis of a cystic pancreatic lesion corresponding to a serous cystadenoma of 14 mm. During a 5-year follow-up (CT and MRT) the lesion tripled in size and a surgical intervention was decided upon. The lesion was thought to have a benign pathology and, in an attempt to preserve the spleen and a major portion of pancreatic tissue, a central pancreatectomy with a diversion of the remaining distal pancreas was carried out. The authors reviewed national and international publications.

Abstract
BACKGROUND AND OBJECTIVES Imaging of the pancreas for detection of neuroendocrine tumors is indicated as surveillance in multiple endocrine neoplasia type 1 (MEN1) or if typical clinical symptoms combined with hormone production raise the suspicion of a neuroendocrine tumor. Endoscopic ultrasound (EUS) is considered the best imaging modality to detect small pancreatic tumors. However, little is known about how small pancreatic neuroendocrine tumors (pNETs) present on EUS. PATIENTS AND METHODS In this multicenter study, we retrospectively analyzed the endosonographic characteristics of small pNETs which had been detected due to typical biochemistry and clinical symptoms or during surveillance of MEN 1. Only small pancreatic tumors ≤15 mm with histological confirmation as pNET were included. B-mode and contrast-enhanced ultrasound- and EUS patterns were analyzed. RESULTS Among 32 patients with histologically proven small pNETs, 7 patients had known MEN1. Among the pNETs, 20 were insulinoma, 2 gastrinoma, 3 glucagonoma, 6 nonfunctional in MEN1, and one PPoma. 94% of the pNET appeared hypoechogenic, only 1 isoechogenic and 1 hyperechogenic. After contrast injection, 90% of the pNETS showed hyperenhancement compared to the surrounding pancreatic parenchyma. CONCLUSION The high spatial resolution of EUS allows detection and even cytological confirmation of pNET <7 mm diameter. Hypoechogenicity in B-mode and hyperenhancement after injection of contrast agents are endosonographic characteristics of small pNET and present in >90% of pNETs.

Abstract
Pancreatic hamartoma is an extremely rare, non-neoplastic, mass-forming lesion that may be mistaken for malignancy, and the pre-operative diagnosis is particularly challenging. The published literature contains only 23 cases of pancreatic hamartoma. The majority of the cases reported patients with a single benign tumor-like disease that received a pancreatectomy. Immunohistochemical findings confirmed the diagnosis following surgery. The current study reports the case of a 53-year-old female who presented to the Department of Abdominal Surgery, Chinese Academy of Medical Sciences, Cancer Hospital (Beijing, China), due to abdominal pain. Abdominal magnetic resonance imaging revealed a 22×14-mm mass in the head of the pancreas. The patient was pre-operatively diagnosed with a pancreatic space-occupying lesion, and subsequently underwent a pancreaticoduodenectomy. The post-operative course was uneventful. Histological examination of the resected lesion resulted in a diagnosis of pancreatic hamartoma. There were no signs of recurrence at 55 months post-surgery.

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
Cystic neoplasms and neuroendocrine adenomas of the pancreas are detected increasingly more frequently and in up to 50 % as asymptomatic tumors. Intraductal papillary mucinous neoplasms, mucinous cystic neoplasms and solid pseudopapillary neoplasms are considered to be premalignant lesions with different rates of malignant transformation. The most frequent neuroendocrine adenomas are insulinomas. Neuroendocrine adenomas are considered to be potentially malignant, inherent to the lesion and development is unpredictable. Standard surgical treatment for pancreatic tumors are the Kausch-Whipple resection, left hemipancreatectomy and total pancreatectomy depending on the location; however, the application of standard surgical procedures, which are usually multiorgan resections for benign, premalignant and low-risk cancers of the pancreas have to be balanced against the risk for early postoperative morbidity, hospital mortality of 1.5-7 % and loss of endocrine and exocrine pancreatic functions in 12-30 %. Tumor enucleation, pancreatic middle segment resection and duodenum-preserving total pancreatic head (DPPHR-T/S) resection are parenchyma-preserving, local resection procedures, which are associated with a low early postoperative rate of severe complications, hospital mortality up to 1.3 % and maintenance of exocrine and endocrine pancreatic functions in more than 90 %. Tumor enucleation bears the risk of pancreatic fistulas (<33 %) and a limitation is proximity to the pancreatic main duct. The main risk for pancreatic middle segment resection is early postoperative pancreatic fistulas (up to 40 %), early postoperative intra-abdominal hemorrhage and a reintervention frequency up to 15 %. The DPPHR-T/S resection is applied for cystic neoplastic lesions in 90 %, severe postoperative complications are below 15 % and the 90-day hospital mortality is 0.5 %. Pancreatic fistulas are observed in less than 20 % with a recurrence rate of <1 %. These facts and maintenance of exocrine and endocrine pancreatic functions are advantages compared with the Kausch-Whipple resection of the pancreatic head. The use of tumor enucleation, particularly for neuroendocrine tumors and pancreatic middle segment resection as well as total DPPHR resection should replace the pancreatoduodenectomy for lesions in the pancreatic head and hemipancreatectomy for lesions in the pancreatic body and tail.

Parenchyma-Sparing, Limited Pancreatic Head Resection for Benign Tumors and Low-Risk Periampullary Cancer--a Systematic Review. J Gastrointest Surg 2016; 20:206-17.

Abstract
BACKGROUND Parenchyma-sparing local extirpation of benign tumors of the pancreatic head provides the potential benefits of preservation of functional tissue and low postoperative morbidity. METHODS Medline/PubMed, Embase, and Cochrane library databases were surveyed for studies performing limited resection of the pancreatic head and resection of a segment of the duodenum and common bile duct or preservation of the duodenum and common bile duct (CBD). The systematic analysis included 27 cohort studies that reported on limited pancreatic head resections for benign tumors. In a subgroup analysis, 12 of the cohort studies were additionally evaluated to compare the postoperative morbidity after total head resection including duodenal segment resection (DPPHR-S) and total head resection conserving duodenum and CBD (DPPHR-T). RESULTS Three hundred thirty-nine of a total of 503 patients (67.4%) underwent total head resections. One hundred forty-seven patients (29.2%) of them underwent segmental resection of the duodenum and CBD (DPPHR-S) and 192 patients (38.2%) underwent preservation of duodenum and CBD. One hundred sixty-four patients experienced partial head resection (32.6%). The final histological diagnosis revealed in 338 of 503 patients (67.2%) cystic neoplasms, 53 patients (10.3%) neuroendocrine tumors, and 20 patients (4.0%) low-risk periampullary carcinomas. Severe postoperative complications occurred in 62 of 490 patients (12.7%), pancreatic fistula B + C in 40 of 295 patients (13.6%), resurgery was experienced in 2.7%, and delayed gastric emptying in 12.3%. The 90-day mortality was 0.4%. The subgroup analysis comparing 143 DPPHR-S patients with 95 DPPHR-T patients showed that the respective rates of procedure-related biliary complications were 0.7% (1 of 143 patients) versus 8.4% (8 of 95 patients) (p ≤ 0.0032), and rates of duodenal complications were 0 versus 6.3% (6 of 95 patients) (p ≤ 0.0037). DPPHR-S was associated with a higher rate of delay of gastric emptying compared to DPPHR-T (18.9 vs. 2.1%, p ≤ 0.0001). CONCLUSION Parenchyma-sparing, limited head resection for benign tumors preserves functional pancreatic and duodenal tissue and carries in terms of fistula B + C rate, resurgery, rehospitalization, and 90-day mortality a low risk of postoperative complications. A subgroup analysis exhibited after total pancreatic head resection that preserves the duodenum and CBD an association with a significant increase in procedure-related biliary and duodenal complications compared to total head resection combined with resection of the periampullary segment of the duodenum and resection of the intrapancreatic CBD.

Abstract
Pancreatic surgery for malignancy is recognized as challenging for the surgeons and risky for the patients due to consistent perioperative morbidity and mortality. Furthermore, the oncological long-term results are largely disappointing, even for those patients who experience an uneventfully hospital stay. Nevertheless, surgery still remains the cornerstone of a multidisciplinary treatment for pancreatic cancer. In order to maximize the benefits of surgery, the advent of both laparoscopy and robotics has led many surgeons to treat pancreatic cancers with these new methodologies. The reduction of postoperative complications, length of hospital stay and pain, together with a shorter interval between surgery and the beginning of adjuvant chemotherapy, represent the potential advantages over conventional surgery. Lastly, a better cosmetic result, although not crucial in any cancerous patient, could also play a role by improving overall well-being and patient self-perception. The laparoscopic approach to pancreatic surgery is, however, difficult in inexperienced hands and requires a dedicated training in both advanced laparoscopy and pancreatic surgery. The recent large diffusion of the da Vinci® robotic platform seems to facilitate many of the technical maneuvers, such as anastomotic biliary and pancreatic reconstructions, accurate lymphadenectomy, and vascular sutures. The two main pancreatic operations, distal pancreatectomy and pancreaticoduodenectomy, are approachable by a minimally invasive path, but more limited interventions such as enucleation are also feasible. Nevertheless, a word of caution should be taken into account when considering the increasing costs of these newest technologies because the main concerns regarding these are the maintenance of all oncological standards and the lack of long-term follow-up. The purpose of this review is to examine the evidence for the use of minimally invasive surgery in pancreatic cancer (and less aggressive tumors), with particular attention to the oncological results and widespread reproducibility of each technique.

Abstract
Classic pancreatectomy procedures usually require resection of the pancreas and surrounding organs, having disadvantages of major trauma, long hospital stay and high morbidity. In order to preserve organ function as much as possible, many types of organ preserving pancreatectomy have been widely used in the treatment of benign pancreatic tumors and low-grade malignant lesions, including tumor enucleation, pylorus preserving pancreaticoduodenectomy, duodenum-preserving pancreatic head resection, middle segmental pancreatectomy, and spleen-preserving distal pancreatectomy. With the development of minimally invasive techniques in recent years, laparoscopic and robotic techniques have been also safely applied in organ preserving pancreatectomy. This article will review the current research status of organ preserving pancreatectomy.

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.
