Review
Gastric cancer is a malignant neoplasm of the gastrointestinal tract, with one of the standard treatment methods remaining gastrectomy. The authors conducted a systemic review of the Medline and Embase databases concerning the serum vitamin D level in post-gastrectomy gastric cancer patients, regarding all articles published until 22 May 2022 according to the PRISMA guidelines. 18 studies with a total number of 908 gastric cancer survivors were included in the analysis. The initial rate of vitamin D deficiency in gastric cancer patients undergoing gastrectomy appears to be similar to the global population deficiency. In post-gastrectomy survivors, the level of 25(OH)D may remain stable or decrease, while the level of 1, 25(OH)D remains normal. Supplementation with vitamin D results in an improvement in its serum concentration and positively affects bone mineral density, which is gradually reduced in post-gastrectomy survivors. Combining vitamin D supplementation with calcium and bisphosphonates enables us to obtain better results than vitamin D and calcium only. The type of surgery influences the level of serum vitamin D and its metabolites, with total or partial gastrectomy and maintenance of the duodenal food passage remaining the most important factors. There is a strong need for randomized, controlled trials that would investigate this matter in the future.

BACKGROUND AND AIMS
Somatostatinoma of the ampulla of Vater (SAV) is a rare neuroendocrine tumor that usually appears with atypical clinical manifestations and is associated with Von Recklinghausen's disease. The aims of this study were to systematically review the literature regarding SAV and to highlight the clinicopathological characteristics and optimal therapeutic management of this rare entity.
METHODS
A systematic search of the literature in PubMed/Medline and Scopus databases was performed by two independent investigators, including all case reports and case series concerning SAVs from 1980 until September 2021.
RESULTS
In total, 37 articles were retrieved, including 43 patients, with a male to female ratio of 1.8:1 and a mean age of 46.8 ± 11.3 years (mean, SD). For 23 out of 43 patients (53.5%), Von Recklinghausen's disease was proved. The main clinical manifestations were abdominal pain (41.9%), jaundice (27.9%), weight loss (20.9%) and bowel disorders (20.9%). Typical histological findings included psammoma bodies, nests or clusters of epithelial cells with eosinophilic cytoplasm, while somatostatin staining was positive in 35 patients (81.4%), chromogranin-A in 21 patients (48.8%) and synaptophysin in 18 patients (41.9%). Surgery was the initial therapeutic approach in 34 patients (79.1%), whereas Whipple's procedure was the preferred surgical approach in 23 patients (53.4%). The longest survival among included patients was 13 years and only two postoperative deaths (4.7%) were reported.
CONCLUSIONS
Somatostatinomas of the ampulla of Vater are rare malignancies that require increased physicians' suspicion and accurate surgical approach in order to achieve optimal therapeutic results.

Long-term survival after minimally invasive resection versus open pancreaticoduodenectomy for periampullary cancers: a systematic review, meta-analysis and meta-regression.
BACKGROUND
It remains unclear whether minimally invasive pancreaticoduodenectomy (MIPD) and open pancreaticoduodenectomy (OPD) influences long-term survival in periampullary cancers. This review aims evaluate long-term survival between MIPD and OPD for periampullary cancers.
METHODS
A systematic review was performed to identify studies comparing long-term survival after MIPD and OPD. The I test was used to test for statistical heterogeneity and publication bias using Egger test. Random-effects meta-analysis was performed for all-cause 5-year (main outcome) and 3-year survival, and disease-specific 5-year and 3-year survival. Meta-regression was performed for the 5-year and 3-year survival outcomes with adjustment for study (region, design, case matching), hospital (centre volume), patient (ASA grade, gender, age), and tumor (stage, neoadjuvant therapy, subtype (i.e. ampullary, distal bile duct, duodenal, pancreatic)). Sensitivity analyses performed on studies including pancreatic ductal adenocarcinoma (PDAC) only.
RESULTS
The review identified 31 relevant studies. Among all 58,622 patients, 8716 (14.9%) underwent MIPD and 49,875 (85.1%) underwent OPD. Pooled analysis revealed similar 5-year overall survival after MIPD compared with OPD (HR: 0.78, 95% CI 0.50-1.22, p = 0.2). Meta-regression indicated case matching, and ASA Grade II and III as confounding covariates. The statistical heterogeneity was limited (I = 12, χ = 0.26) and the funnel plot was symmetrical both according to visual and statistical testing (Egger test = 0.32). Sensitivity subset analyses for PDAC demonstrated similar 5-year overall survival after MIPD compared with OPD (HR 0.69, 95% CI: 0.32-1.50, p = 0.3).
CONCLUSION
Long-term survival after MIPD is non-inferior to OPD. Thus, MIPD can be recommended as a standard surgical approach for periampullary cancers.

Objective Risks of bleeding and pancreatitis after mucosal resection using the purecut/autocut and blendcut/endocut modes for endoscopic papillectomy have not been fully clarified. Thus, a systematic review on electrosurgical cutting modes for endoscopic papillectomy was conducted focusing on the types and incidence of adverse events. Methods We searched the PubMed and Cochrane library for cases of endoscopic papillectomy recorded as of April 2017. Studies reporting the methods of electrically excising a tumor in the duodenal papilla and the number of adverse events were extracted. Studies were collected and examined separately based on the electrosurgical cutting mode, and the incidence rate for each adverse event was summarized. Results A total of 159 relevant articles were found; among them, 20 studies were included and 139 excluded. Five studies analyzed endoscopic papillectomy with the purecut/autocut mode and 16 with the blendcut/endocut mode. Only one study investigated both modes (purecut and endocut). With the purecut/autocut mode, the incidence of bleeding was 2.8-50%, and that of pancreatitis was 0-50% (mean: 12.8%). With the blendcut/endocut mode, the incidence of bleeding was 0-42.3%, and that of pancreatitis was 0%-17.9% (mean: 9.5%). Conclusion Both methods had high adverse event rates for endoscopic papillectomy. Thus, a standard method of endoscopic papillectomy, including the electrosurgical cutting mode, needs to be established.

Review
BACKGROUND
Post-pancreatectomy bleeding is a potentially fatal complication which results from the erosion of the regional visceral arteries, mainly the hepatic artery and stump of the gastro-duodenal artery, caused by a leak or fistula from the pancreatic anastomosis. The objective of this article is to assess whether wrapping of regional vessels with omentum or falciform/teres ligament following pancreaticoduodenectomy reduces the risk of extra-luminal bleeding.
MATERIALS AND METHOD
Standard medical electronic databases were searched with the help of a local librarian and relevant published randomised controlled trials (RCT) and any type of comparative trial were shortlisted according to the inclusion criteria. The summated outcome of post-operative extra-luminal bleeding in patients undergoing pancreaticoduodenectomy was evaluated using the principles of meta-analysis on RevMan 5 statistical software.
RESULT
Two RCTs and 5 retrospective studies on 4100 patients undergoing pancreaticoduodenectomy were found suitable for this meta-analysis. There were 1404 patients in the wrapping-group (WG) and 2696 patients in the no-wrapping group (NWG). In the random effects model analysis, the incidence of extra-luminal haemorrhage was statistically lower in WG [odds ratio 0.51, 95%, CI (0.31, 0.85), Z = 2.59, P = 0.01]. There was moderate heterogeneity between the studies; however it was not statistically significant.
CONCLUSION
The wrapping of regional vessels (using omentum, falciform ligament or ligamentum teres) following pancreaticoduodenectomy seems to reduce the risk of post-operative extra-luminal bleeding. However, more RCTs of robust quality recruiting a greater number of patients are required to validate these findings as this study presents the combined data of two RCTs and 5 retrospective studies.

Comparative Study Meta-Analysis
BACKGROUND
By comparing the long-term prognostic outcomes after pancreaticoduodenectomy (PD) and limited resection (LR), this study aimed to investigate the optimal surgical modality for duodenal gastrointestinal stromal tumors (GISTs).
METHODS
Two authors independently searched PubMed, Web of Science, Embase, and the Cochrane Library for published articles comparing the long-term prognostic and clinicopathological factors of duodenal GIST patients undergoing PD versus LR. Relevant information was extracted and analyzed.
RESULTS
After screening, 10 items comprising 623 cases were eventually included. This meta-analysis explicitly indicated that PD treatment was associated with worse long-term prognosis (hazard ratio = 1.93; 95% confidence interval [CI], 1.39-2.69; p < 0.001; I = 0) and more complications (odds ratio [OR] = 2.90; 95% CI, 1.90-4.42; p < 0.001; I = 10%) than LR treatment. Nevertheless, for duodenal GISTs, PD was related to the following clinicopathological features: invasion of the second part of the duodenum (OR = 3.39; 95% CI, 1.69-6.79; p < 0.001; I = 50%), high-degree tumor mitosis (> 5/50 high-power fields; OR = 2.24; 95% CI, 1.42-3.52; p < 0.001; I = 0), and high-risk classification (OR = 3.17; 95% CI; 2.13-4.71; p < 0.001; I = 0).
CONCLUSIONS
Since PD is associated with worse long-term prognosis and more complications, its safety and efficacy should be ascertained. Our findings recommend the use of LR to obtain negative incision margins when conditions permit it.

Meta-Analysis
BACKGROUND
The role of prophylactic drainage (PD) in gastrectomy for gastric cancer (GC) is not well-established. The purpose of this study is to compare the perioperative outcomes between the PD and non-drainage (ND) in GC patients undergoing gastrectomy.
METHODS
A systematic review of electronic databases including PubMed, Embase, Web of Science, the Cochrane Library, and China National Knowledge Infrastructure was performed up to December 2022. All eligible randomized controlled trials (RCTs) and observational studies were included and meta-analyzed separately. The registration number of this protocol is PROSPERO CRD42022371102.
RESULTS
Overall, 7 RCTs (783 patients) and 14 observational studies (4359 patients) were ultimately included. Data from RCTs indicated that patients in the ND group had a lower total complications rate (OR = 0.68; 95%CI:0.47-0.98; P = 0.04; I = 0%), earlier time to soft diet (MD = - 0.27; 95%CI: - 0.55 to 0.00; P = 0.05; I = 0%) and shorter length of hospital stay (MD = - 0.98; 95%CI: - 1.71 to - 0.26; P = 0.007; I = 40%). While other outcomes including anastomotic leakage, duodenal stump leakage, pancreatic leakage, intra-abdominal abscess, surgical-site infection, pulmonary infection, need for additional drainage, reoperation rate, readmission rate, and mortality were not significantly different between the two groups. Meta-analyses on observational studies showed good agreement with the pooled results from RCTs, with higher statistical power.
CONCLUSION
The present meta-analysis suggests that routine use of PD may not be necessary and even harmful in GC patients following gastrectomy. However, well-designed RCTs with risk-stratified randomization are still needed to validate the results of our study.

BACKGROUND
Resection of the para-aortic lymph node (PALN) group Ln16b1 during pancreatoduodenectomy remains controversial because PALN metastases are associated with a worse prognosis in pancreatic cancer patients. The present study aimed to analyze the impact of PALN metastases on outcome after non-pancreatic periampullary cancer resection.
METHODS
One hundred sixty-four patients with non-pancreatic periampullary cancer who underwent curative pancreatoduodenectomy or total pancreatectomy between 2005 and 2016 were retrospectively investigated. The data were supplemented with a systematic literature review on this topic.
RESULTS
In 67 cases, the PALNs were clearly assigned and could be histopathologically analyzed. In 10.4% of cases (7/67), tumor-infiltrated PALNs (PALN+) were found. Metastatic PALN+ stage was associated with increased tumor size (P = 0.03) and a positive nodal stage (P < 0.001). The median overall survival (OS) of patients with metastatic PALN and non-metastatic PALN (PALN-) was 24.8 and 29.5 months, respectively. There was no significant difference in the OS of PALN+ and pN1 PALN patients (P = 0.834). Patients who underwent palliative surgical treatment (n = 20) had a lower median OS of 13.6 (95% confidence interval 2.7-24.5) months. Including the systematic literature review, only 23 cases with PALN+ status and associated OS could be identified; the average survival was 19.8 months.
CONCLUSION
PALN metastasis reflects advanced tumor growth and lymph node spread; however, it did not limit overall survival in single-center series. The available evidence of the prognostic impact of PALN metastasis is scarce and a recommendation against resection in these cases cannot be given.

Differences in Lymph Node Metastases Patterns Among Non-pancreatic Periampullary Cancers and Histologic Subtypes: An International Multicenter Retrospective Cohort Study and Systematic Review.
BACKGROUND
Standard lymphadenectomy for pancreatoduodenectomy is defined for pancreatic ductal adenocarcinoma and adopted for patients with non-pancreatic periampullary cancer (NPPC), ampullary adenocarcinoma (AAC), distal cholangiocarcinoma (dCCA), or duodenal adenocarcinoma (DAC). This study aimed to compare the patterns of lymph node metastases among the different NPPCs in a large series and in a systematic review to guide the discussion on surgical lymphadenectomy and pathology assessment.
METHODS
This retrospective cohort study included patients after pancreatoduodenectomy for NPPC with at least one lymph node metastasis (2010-2021) from 24 centers in nine countries. The primary outcome was identification of lymph node stations affected in case of a lymph node metastasis per NPPC. A separate systematic review included studies on lymph node metastases patterns of AAC, dCCA, and DAC.
RESULTS
The study included 2367 patients, of whom 1535 had AAC, 616 had dCCA, and 216 had DAC. More patients with pancreatobiliary type AAC had one or more lymph node metastasis (67.2% vs 44.8%; P < 0.001) compared with intestinal-type, but no differences in metastasis pattern were observed. Stations 13 and 17 were most frequently involved (95%, 94%, and 90%). Whereas dCCA metastasized more frequently to station 12 (13.0% vs 6.4% and 7.0%, P = 0.005), DAC metastasized more frequently to stations 6 (5.0% vs 0% and 2.7%; P < 0.001) and 14 (17.0% vs 8.4% and 11.7%, P = 0.015).
CONCLUSION
This study is the first to comprehensively demonstrate the differences and similarities in lymph node metastases spread among NPPCs, to identify the existing research gaps, and to underscore the importance of standardized lymphadenectomy and pathologic assessment for AAC, dCCA, and DAC.

Meta-Analysis
Ampullary cancer is a relatively rare gastrointestinal malignancy. The purpose of this study was to evaluate prognostic factors for survival and assess the benefits of adjuvant therapy following pancreaticoduodenectomy for this entity. Medline and EMBASE databases were searched to identify eligible studies from January 2000 to August 2019. Review Manager 5.3 statistical software was used for meta-analysis. 71 studies met the inclusion criteria and were included in the analysis for a total of 8280 patients. The median (range) 5-year overall survival and disease-free survival rates were 58% (32-82%) and 51% (28-73%) respectively. In meta-analysis, age >65 years at diagnosis, tumor size >20 mm, poor differentiation, pancreaticobiliary histotype, pT3-4 stage disease, presence of metastatic lymph node, number of metastatic nodes, perineural invasion, lymphovascular invasion, vascular invasion, pancreatic invasion, and positive surgical margins were independently associated with worse overall survival, whereas adjuvant therapy was associated with improved overall survival. In summary, in patients with ampullary cancer undergoing pancreaticoduodenectomy, tumor factors are the main predictors of worse survival and adjuvant treatment confers a survival benefit.
