Meta-Analysis Review
BACKGROUND
Minimally Invasive Pancreatic Enucleation, either laparoscopic or robot-assisted, is rarely performed. The aim of this study was to offer the current available evidence about the outcomes of minimally invasive pancreatic enucleations and explore the possible advantage of this approach over traditional surgery.
METHODS
PubMed (MEDLINE), Cochrane Library and Embase (ELSEVIER) medical databases were searched for articles published from January 1990 to March 2022. Studies which included more than 10 cases of minimally-invasive pancreatic enucleation were included. Data on the outcomes were synthetized and meta-analyzed when appropriate.
RESULTS
Twenty studies published between 2009 and 2022 with a total of 552 patients were included in the systematic review: three hundred fifty-one patients (63.5%) had a laparoscopic intervention, two hundred and one (36.5%) robot-assisted with a cumulative incidence of conversion rate of 5%. Minimally-invasive surgery was performed in 63% of cases on the body/tail of the Pancreas and in 37% of the cases on the head/uncinate process of the Pancreas. The cumulative post-operative 30 days - mortality rate was 0.2% and the major postoperative morbidity (Clavien-Dindo III-IV-V) 35%. Clinically relevant pancreatic fistula was observed in 17% of the patients. Compared with the standardized open approach (n: 366 patients), mean length of hospital stay was significantly reduced in patients undergoing minimally invasive pancreatic enucleation (2.45 days, p = 0.003) with a favorable trend for post-operative major morbidity (Clavien-Dindo III-IV) (- 24% RR, p: 0.13). Operative time, blood loss and clinically relevant pancreatic fistula rate were comparable between the two groups. One hundred and fourteen robot-assisted enucleations entered in a subgroup analysis with comparable results to open surgery.
CONCLUSION
Minimally-Invasive approach for pancreatic enucleation is safe, feasible and offers short-term clinical outcomes comparable with open surgery. The potential benefit of robotic surgery will need to be verified in further studies.

Prophylactic total pancreatectomy in individuals at high risk of pancreatic ductal adenocarcinoma (PROPAN): systematic review and shared decision-making programme using decision tables.
BACKGROUND
Individuals with a very high lifetime risk of developing pancreatic ductal adenocarcinoma; for example, hereditary pancreatitis and main-duct or mixed-type intraductal papillary mucinous neoplasm, may wish to discuss prophylactic total pancreatectomy but strategies to do so are lacking.
OBJECTIVE
To develop a shared decision-making programme for prophylactic total pancreatectomy using decision tables.
METHODS
Focus group meetings with patients were used to identify relevant questions. Systematic reviews were performed to answer these questions.
RESULTS
The first tables included hereditary pancreatitis and main-duct or mixed-type intraductal papillary mucinous neoplasm. No studies focused on prophylactic total pancreatectomy in these groups. In 52 studies (3570 patients), major morbidity after total pancreatectomy was 25% and 30-day mortality was 6%. After minimally invasive total pancreatectomy (seven studies, 35 patients) this was, respectively, 13% and 0%. Exocrine insufficiency-related symptoms occurred in 33%. Quality of life after total pancreatectomy was slightly lower compared with the general population.
CONCLUSION
The decision tables can be helpful for discussing prophylactic total pancreatectomy with individuals at high risk of pancreatic ductal adenocarcinoma.

BACKGROUND
Morbidity and mortality from post-pancreatectomy haemorrhage (PPH) remains high. The International Study Group of Pancreatic Surgery (ISGPS) published guidelines to standardise definitions of PPH severity, management and reporting. This study aimed to i) identify the number of studies reporting PPH using ISGPS guidelines (Grade A, B or C) and ii) describe treatment modality success by grade.
METHODS
A systematic literature review was performed, identifying studies reporting PPH by ISGPS Grade and their subsequent management.
RESULTS
Of 62 studies reporting on PPH management, 17 (27.4%) stratified by ISGPS guidelines and included 608 incidences of PPH: 48 Grade A, 274 Grade B (62 early, 166 late, 46 unspecified) and 286 Grade C. 96% of Grade A PPH were treated conservatively. Of 62 early Grade B, 54.8% were managed conservatively and 37.1% surgically. Late Grade B were managed non-operatively in 25.3% (42/166), with successful endoscopy in 90.9% (10/11) and angiography in 90.3% (28/31). In Grade C, endoscopic treatment was successful in 64.4% (29/45) and angiography in 90.8% (108/119). Surgical intervention was required in 43.5% early Grade B, 7.8% late Grade B and 33.2% Grade C.
CONCLUSION
PPH grading is underreported and despite guidelines, inconsistencies remain when using definitions and reporting of outcomes.

Review
OBJECTIVE
The aim of the study was to determine if there had been any change in the number of solid-pseudopapillary neoplasm (SPN) cases detected and their evaluation or management over time.
METHODS
A systematic review of SPN was performed of all articles published in English in PubMed and Scopus.
RESULTS
A total of 2744 patients with SPN were identified in 484 studies published between 1961 and 2012; 87.8% of the cases were reported between 2000 and 2012. A total of 2408 (87.8%) were females, and the mean age was 28.5 (SD, 13.7) years. The most common symptom was abdominal pain in 63.6% of the cases and incidentally detected in 38.1% of the cases. There were 2285 patients who underwent pancreatic resection. The mean tumor size was 8.6 (SD, 4.3) cm. Follow-up was reported for 1952 (90.5%) patients, with a mean follow-up of 36.1 (SD, 32.8) months. Disease-free survival was documented in 1866 (95.6%) patients with recurrence in 86 (4.4%) patients; the median time to recurrence was 50.5 months.
CONCLUSIONS
The number of SPNs reported in the literature has seen a 7-fold increase in the number of cases reported since 2000 compared with before. Solid-pseudopapillary neoplasms continue to be primarily found in young women and present with nonspecific symptoms. Surgery remains the mainstay of treatment with an excellent long-term prognosis.

Review
BACKGROUND
Surgical resection is a part of the treatment pathways for the management of pancreatic cancer with arterial involvement. Arterial resection in this context is however not widely supported due to the paucity and diversity of the reported evidence in the literature. The aim of this systematic review is the presentation and analysis of the current evidence in the field.
METHODS
A systematic literature search of PubMed, MEDLINE and the Cochrane Library was performed for eligible studies, following the PRISMA guidelines. Information on baseline characteristics, peri-operative outcomes, survival outcomes and histopathological findings were extracted for pooling and analysis.
RESULTS
Eight studies with a total of 170 patients were included in the analysis. One hundred and thirty-five patients had a pancreaticoduodenectomy (PD) and 35 had a total pancreatectomy (TP) with arterial resection. Perioperative morbidity was 43.5% and mortality was 4.5%. Median overall survival (OS) was 12.7 months (range, 10.5-22.2 months). Overall 3- and 5-year survival for this cohort was reported at 6.6% (range, 0-42.4%) and 3.3% (range, 0-6.6%) respectively. Resection margins were clear (R0) in a median of 75% of patients. Only a median of 45% of patients received neo-adjuvant chemotherapy.
CONCLUSIONS
Arterial resection can be performed with an acceptable peri-operative morbidity and mortality. However, survival outcomes are still not convincing and future efforts should concentrate on patient and disease biology selection.

Meta-Analysis
BACKGROUND
Pancreatectomy is the only curative treatment available for pancreatic cancer and a necessity for patients with challenging pancreatic pathology. To optimize outcomes, postsurgical complications such as clinically relevant postoperative pancreatic fistula (CR-POPF) should be minimized. Central to this is the ability to predict and diagnose CR-POPF, potentially through drain fluid biomarkers. This study aimed to assess the utility of drain fluid biomarkers for predicting CR-POPF by conducting a diagnostic test accuracy systematic review and meta-analysis.
METHODS
Five databases were searched for relevant and original papers published from January 2000 to December 2021, with citation chaining capturing additional studies. The QUADAS-2 tool was used to assess the risk of bias and concerns regarding applicability of the selected studies.
RESULTS
Seventy-eight papers were included in the meta-analysis, encompassing six drain biomarkers and 30 758 patients with a CR-POPF prevalence of 17.42%. The pooled sensitivity and specificity for 15 cut-offs were determined. Potential triage tests (negative predictive value >90%) were identified for the ruling out of CR-POPF and included postoperative day 1 (POD1) drain amylase in pancreatoduodenectomy (PD) patients (300 U/l) and in mixed surgical cohorts (2500 U/l), POD3 drain amylase in PD patients (1000-1010 U/l) and drain lipase in mixed surgery groups (180 U/l). Notably, drain POD3 lipase had a higher sensitivity than POD3 amylase, while POD3 amylase had a higher specificity than POD1.
CONCLUSIONS
The current findings using the pooled cut-offs will offer options for clinicians seeking to identify patients for quicker recovery. Improving the reporting of future diagnostic test studies will further clarify the diagnostic utility of drain fluid biomarkers, facilitating their inclusion in multivariable risk-stratification models and the improvement of pancreatectomy outcomes.

Meta-Analysis Review
AIM
The beneficial of immunonutrition on overall morbidity and mortality remains uncertain. We undertook a systematic review to evaluate the effects of immune-enhancing enteral nutrition (IEN) in upper gastrointestinal (GI) surgery.
METHODS
Main electronic databases [MEDLINE via Pubmed, EMBASE, Scopus, Web of Knowledge, Cochrane Central Register of Controlled Trials (CENTRAL) and the Cochrane Library, and clinical trial registry (ClinicalTrial.gov)] were searched for studies reported clinical outcomes comparing standard enteral nutrition (SEN) and immunonutrition (IEN). The systematic review was conducted in accordance with the PRISMA guidelines and meta-analysis was analysed using fixed and random-effects models.
RESULTS
Nineteen RCTs with a total of 2016 patients (1017 IEN and 999 SEN) were included in the final pooled analysis. The ratio of patients underwent oesophagectomy:gastrectomy:pancreatectomy was 2.2:1.2:1.0. IEN, when administered post-operatively, was associated with a significantly lower risk of wound infection (risk ratio (RR) 0.59, 95% confidence interval (CI) 0.40 to 0.88; p = 0.009) and shorter length of hospital stay (MD -2.92 days, 95% CI -3.89 to -1.95; p < 0.00001). No significant differences in other post-operative morbidities of interest (e.g. anastomotic leak and pulmonary infection) and mortality between the two groups were identified.
CONCLUSIONS
Overall, our analysis found that IEN decreases wound infection rates and reduces length of stay. It should be recommended as routine nutritional support as part of the Enhanced Recovery after Surgery (ERAS) programmes for upper GI Surgery.

Meta-Analysis
BACKGROUND
Pancreaticoduodenectomy (PD) is a complex and traumatic abdominal surgery with a high risk of postoperative complications. Nutritional support, including immunonutrition (IMN) with added glutamine, arginine, and ω-3 polyunsaturated fatty acids, can improve patients' prognosis by regulating postoperative inflammatory response. However, the effects of IMN on PD patients' outcomes require further investigation.
METHODS
PMC, EMbase, web of science databases were used to search literatures related to IMN and PD. Data such as length of hospital stay, infectious complications, non-infectious complications, postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), mortality, systemic inflammatory response syndrome (SIRS) duration, IL-6, and C-reactive protein (CRP) were extracted, and meta-analyses were performed on these data to study their pooled results, heterogeneity, and publication bias.
RESULTS
This meta-analysis involved 10 studies and a total of 572 patients. The results showed that the use of IMN significantly reduced the length of hospital stay for PD patients (MD = -2.31; 95% CI = -4.43, -0.18; P = 0.03) with low heterogeneity. Additionally, the incidence of infectious complications was significantly reduced (MD = 0.42; 95% CI = 0.18, 1.00, P = 0.05), with low heterogeneity after excluding one study. However, there was no significant impact on non-infectious complications, the incidence of POPF and DGE, mortality rates, duration of SIRS, levels of IL-6 and CRP.
CONCLUSION
The use of IMN has been shown to significantly shorten hospital stays and decrease the frequency of infectious complications in PD patients. Early implementation of IMN is recommended for those undergoing PD. However, further research is needed to fully assess the impact of IMN on PD patients through larger and higher-quality studies.

Review
BACKGROUND
Pancreatic trauma is an uncommon injury that occurs usually in a young population and is frequently overlooked and not readily appreciated on initial examination. Nowadays, the diagnosis and management of pancreatic trauma are still controversial, and there is no gold standard for the treatment. The aim of this study is to describe our experience in the management of blunt pancreatic trauma with a laparoscopic approach and review the literature on laparoscopic management of pancreatic trauma.
METHODS
A systematic literature review was performed, and 40 cases were reported and analysed; 10 cases were excluded because the complete data were not retrievable. We also reported our experience with the case of an 18-year-old male diagnosed with a deep laceration of the pancreas between body and tail, involving the main pancreatic duct, and with a concomitant hematoma. The patient underwent exploratory laparoscopy with abdominal toilet, necrosectomy, and suture of main pancreatic duct; the total blood loss was less than 200 ml, and the total operative time was 180 minutes. The patient recovered uneventfully and was discharged on the 6th postoperative day.
RESULTS
30 patients with pancreatic trauma, 10 adults and 20 pediatrics (mean age 28.2 years and 10.5 years), underwent a total laparoscopic approach: 2 distal pancreatic-splenectomy, 22 spleen-preserving distal pancreatectomy, and 6 laparoscopic drainage. The mean operative time for the adult and pediatric populations was 160.6 and 214.5 minutes, the mean estimated blood loss was 400 ml and 75 ml, and the mean hospital stay was 14.9 and 9 days, respectively.
CONCLUSION
Laparoscopic management for pancreatic trauma can be considered feasible and safe when performed by an experienced laparoscopic pancreatic team, and in such a setting, it can be considered a viable alternative to open surgery, offering the well-known benefits of minimally invasive surgery.

BACKGROUND
Hyperinsulinemic hypoglycemia is the most common cause of severe and persistent hypoglycemia in neonates and children. It is a heterogeneous condition with dysregulated insulin secretion, which persists in the presence of low blood glucose levels.
CASE PRESENTATION
We report a case of a 15 year-old male with hyperinsulinemic hypoglycemia, who underwent a subtotal pancreatectomy after inadequate response to medical therapy. Pathological examination was positive for nesidioblastosis (diffuse β-cell hyperplasia by H-E and immunohistochemical techniques). The patient's blood glucose levels normalized after surgery and he remains asymptomatic after 1 year of follow-up. The systematic review allowed us to identify 41 adolescents from a total of 205 cases reported in 22 manuscripts, from a total of 454 found in the original search done in PubMed and Lilacs.
CONCLUSIONS
Although very well reported in children, hyperinsulinemic hypoglycemia can occur in adolescents or young adults, as it happens in our reported case. These patients can be seen, treated and reported by pediatricians or adult teams either way due to the wide age range used to define adolescence. Most of them do not respond to medical treatment, and subtotal distal pancreatectomy has become the elected procedure with excellent long-term response in the vast majority.
