Meta-Analysis
OBJECTIVE
The effect of a pre-operative biliary stent on complications after pancreaticoduodenectomy (PD) remains controversial.
MATERIALS AND METHOD
We conducted a meta-analysis according to the preferred reporting items for systematic reviews and meta-analyses guidelines, and PubMed, Web of Science Knowledge, and Ovid's databases were searched by the end of February 2023. 35 retrospective studies and 2 randomized controlled trials with a total of 12641 patients were included.
RESULTS
The overall complication rate of the pre-operative biliary drainage (PBD) group was significantly higher than the no-PBD group (odds ratio [OR] 1.46, 95% confidence interval [CI] 1.22-1.74; p < 0.0001), the incidence of post-operative delayed gastric emptying was increased in patients with PBD compared those with early surgery (OR 1.21, 95% CI: 1.02-1.43; p = 0.03), and there was a significant increase in post-operative wound infections in patients receiving PBD with an OR of 2.2 (95% CI: 1.76-2.76; p < 0.00001).
CONCLUSIONS
PBD has no beneficial effect on post-operative outcomes. The increase in post-operative overall complications and wound infections urges the exact indications for PBD and against routine pre-operative biliary decompression, especially for patients with total bilirubin < 250 umol/L waiting for PD.

BACKGROUND
With the continuous advancement of cancer treatments, a comprehensive analysis of the impact of multivisceral oncological pancreatic resections on morbidity, mortality, and long-term survival is currently lacking.
OBJECTIVE
This manuscript presents the protocol for a systematic review and meta-analysis designed to summarize the existing evidence concerning the outcomes of multivisceral oncological pancreatic resections across diverse tumor entities.
METHODS
We will conduct a systematic search of the PubMed or MEDLINE, Embase, Cochrane Library, CINAHL, and ClinicalTrials.gov databases in strict accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The predefined outcomes encompass postoperative mortality, postoperative morbidity, overall and disease-free survival (1- to 5-year survival rates), the proportion of macroscopically complete (R0) resections (according to the Royal College of Pathologists definition), duration of hospital stay (in days), reoperation rate (%), postoperative complications (covering all complications according to the Clavien-Dindo classification), as well as pancreatic fistula, postpancreatectomy hemorrhage, and delayed gastric emptying (all according to the definitions of the International Study Group of Pancreas Surgery).
RESULTS
Systematic database searches will begin in July 2024. The completion of the meta-analysis is anticipated by December 2024. Before completion, the literature search will be checked for new publications that must be considered in the context of the work.
CONCLUSIONS
The forthcoming findings will provide an up-to-date overview of the feasibility, safety, and oncological efficacy of multivisceral pancreatic resections across diverse tumor entities. This data will serve as a valuable resource for health care professionals and patients to make well-informed clinical decisions.

AIM
To analysis the change of electrogastrogram (EGG) in patients with type 2 diabetes mellitus (T2DM), and evaluate the prevalence of abnormal gastric electrical rhythm (AGER) and its relative influencing factors.
METHODS
A total of 65 patients with T2DM hospitalized at the Second Affiliated Hospital of Soochow University from Dec. 2020 to Dec. 2021 were included in the cross-sectional study. General information, clinical data, and medical history data of all study subjects, including name, gender, body mass index (BMI), duration of diabetes, anti-diabetic therapies, high blood pressure (HBP) history, smoking history, and medication history, were completely collected. The results of laboratory tests, including biochemical parameters, glycosylated hemoglobin (HbA1c), fasting C-peptide, 2 h postprandial C-peptide, 24 h urine total protein (24 hUTP), urine microalbumin creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) were recorded. EGG, Gastroparesis Cardinal Symptom Index (GCSI), gastric emptying ultrasound, fundus examination, carotid artery ultrasonography, cardiac autonomic function test, heart rate variability (HRV) were all examined and recorded as well. According to the results of EGG, the subjects were divided into normal gastric electrical rhythm (NGER) group and abnormal gastric electrical rhythm (AGER) group.
RESULTS
(1) Fasting blood glucose (FBG), HbA1c, the presence of diabetic peripheral neuropathy (DPN) and diabetic cardiac autonomic neuropathy (DCAN) were significantly higher in the AGER group (p < 0.05). Low frequency (LF) and high frequency (HF), the indicators of HRV, were significantly lower in the AGER group (p < 0.05). In addition, the prevalence of feeling excessively full after meals, loss of appetite, and stomach or belly visibly larger after meals of gastrointestinal symptoms of gastroparesis were significantly higher in the AGER group (p < 0.05). Multiple logistic regression analysis showed that FBG and the prevalence of DCAN were the independent risk factors.
CONCLUSION
AGER was associated with high FBG and the presence of DCAN. EGG examination is recommended for patients with gastrointestinal symptoms and clues of DCAN.

BACKGROUND
The value of the textbook outcome in pancreatic surgery (TOPS) score, a composite measure of surgical performance for quality assurance, was evaluated in a South African tertiary hospital cohort of pancreaticoduodenectomies (PD) performed for adenocarcinoma of the ampulla of Vater (AAV).
METHODS
A review of all patients undergoing a PD for AAV at a single centre between January 1999 and December 2023 was performed. Demographic, operative, pathological and postoperative variables were recorded. Ten clinical and histological variables were used to construct a TOPS score. These included an R0 resection, no postoperative pancreatic fistula (POPF), no bile leak, no post-pancreatectomy haemorrhage, no delayed gastric emptying, no major postoperative complications (< Gr 3 Clavien-Dindo), no readmission to ICU, length of stay ≤ 10 days, no 30-day readmission or intervention and no 30-day mortality. A textbook outcome (TO) was defined as the fulfilment of all 10 variables. In patients in whom TO was not achieved, the reasons for failure were identified. In addition, the number of patients who had major complications and died were categorised as failure to rescue (FTR).
RESULTS
A positive TOPS score was achieved in 27 of 79 (34.2%) patients undergoing a PD. Overall five-year survival after PD was 33.9%. TOPS conferred a significant 1-year survival benefit, 88.9% vs 66.7% (OR 4.12, 95% CI 1.08-15.67, = 0.038). There was no significant difference in 5-year survival between TOPS and non-TOPS patients, 40.0% vs 32.4% (OR 1.39, 95% CI 0.48-3.99, = 0.54). A POPF occurred in 31.6% patients, resulting in a significantly longer hospital admission, 17 vs 10 days (95% CI 2.66-11.34, = 0.0019). Twenty-one (26.6%) patients developed a major complication, five of whom died (FTR = 6.3%).
CONCLUSION
This study confirmed the value of TOPS as a useful measurement to assess hospital quality metrics and short-term survival after PD for AAV. One quarter of patients developed a major complication with a 6.3% FTR.

Meta-Analysis Comparative Study
Isolated Roux-en-Y versus single loop pancreaticojejunal reconstruction after pancreaticoduodenectomy - a systematic review and meta-analysis of randomised controlled trials.
BACKGROUND
Pancreaticoduodenectomy is a complex intra-abdominal operation used for the treatment of benign and malignant disease of the pancreatic head or periampullary region. Despite developments in surgical techniques, pancreaticoduodenectomy is still associated with high rate of postoperative complications. We performed this systematic review and meta-analysis to compare the surgical outcomes of isolated Roux-en-Y pancreaticojejunostomy (IRYPJ), and conventional pancreaticojejunostomy(CPJ).
METHODS
We performed a systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. We searched the following electronic databases - PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and Clinical-Trials.gov. Published trials comparing the efficacy and safety of IRYPJ and CPJ after pancreaticoduodenectomy were evaluated. The search terms were "pancreaticoduodenectomy," "Whipple," "pylorus-preserving pancreaticoduodenectomy," "pancreaticojejunostomy," "Roux-en-Y," and "isolated Roux loop pancreaticojejunostomy." Only randomised controlled trials comparing outcome of IRYPJ and CPJ after pancreaticoduodenectomy were included. The analysed outcome measures were postoperative pancreatic fistula (POPF), clinically relevant POPF (CR-POPF), bile leak and delayed gastric emptying (DGE).
RESULTS
The initial search yielded 342 results but only four randomised control trials fulfilled the inclusion criteria and were included for data synthesis and meta-analysis. Meta-analysis of POPF revealed that IRYPJ is associated with less POPF compared to CPJ but the difference was not statistically significant (risk ratio = 0.58, = 0.56). A similar finding was also observed with CR-POPF (risk ratio = 0.17, = 0.87) and DGE (risk ratio = 0.74, = 0.46).
CONCLUSION
Isolated Roux-en-Y pancreaticojejunostomy is not associated with a superior outcome when compared to CPJ.

The common belief that heat treatment enhances the gastric digestion of proteins is largely based on findings from animal proteins and may not apply to all proteins, particularly plant proteins. Here, we compared the digestion characteristics of soybean protein isolates (SPI) in an semi-dynamic digestion model and found distinct effects of heat treatment on the digestion properties of plant proteins. The results revealed that heat-treated SPIs formed clots during the early stages of digestion, although the clots gradually became smaller and looser as digestion progressed, the systems remained turbid at the end of gastric digestion, indicating the lag in their emptying. Furthermore, heat treatment altered the rheological properties of SPI, resulting in increased viscosity and slower gastric emptying. These effects became more pronounced with increasing heat treatment temperatures. The fluorescence spectrum analysis indicated that heat treatment altered its conformation. This led to protein unfolding and exposure of hydrophobic groups, facilitating the formation of larger aggregates during digestion. Additionally, heat treatment exposed more cleavage sites for gastric proteases, increasing the extent of hydrolysis. Elevated levels of free amino acids and a smaller molecular weight distribution further corroborated these findings. These findings contribute to a deeper understanding of the gastric digestion characteristics of plant proteins and the relationship between protein aggregation structure and the digestion process.

Review
Gastroparesis is a heterogeneous motility disorder characterized by nausea, vomiting, and postprandial fullness. Its diagnosis requires objective documentation of delayed gastric emptying of solid food and exclusion of mechanical obstruction. Its epidemiology is unclear, and the main causes are diabetes mellitus and idiopathic disease. Cardinal symptoms often co-occur. Management involves nutritional assessment, dietary changes, drug evaluation, glycemic control (for patients with diabetes mellitus), and symptom relief. In this review, we explore challenges nongastroenterologists may encounter and how they can use current recommendations to manage patients with gastroparesis.

INTRODUCTION
Depression affects an estimated 350 million people worldwide and is implicated in up to 60% of suicides. Only about 60-70% of patients respond to antidepressant therapy. One of the factors causing patients to not attain therapeutic goals is herb-drug interactions.
OBJECTIVE
To investigate any potential herb-drug interaction that might exist between extract (XAE) or xylopic acid (XA) and selected conventional antidepressants (imipramine, fluoxetine, and venlafaxine) in mice.
METHODS
Dried, powdered fruits of were cold macerated in 70% ethanol to obtain XAE. XA was isolated by cold macerating dried fruits of in petroleum ether, crystallising impure XA with ethyl acetate, and purifying XA crystals with 96% ethanol. Pharmacodynamic interaction was assessed via isobolographic analysis of tail suspension tests of the agents individually and in their respective combinations. Pharmacokinetic interaction was assessed by monitoring the effect of coadministrations on the plasma concentration of antidepressants and xylopic acid via HPLC analysis.
RESULTS
XAE and XA in mice showed significant antidepressant-like activity in the tail suspension test. With interaction indices less than one, synergism of antidepressant effect was observed in the extract/fluoxetine ( = 0.502), extract/imipramine ( = 0.322), extract/venlafaxine ( = 0.601), xylopic acid/imipramine ( = 0.556), xylopic acid/venlafaxine ( = 0.451), and xylopic acid/fluoxetine ( = 0.298) combinations, which may be potentially due to elevation of serotonergic neurotransmission via varying mechanisms. The AUC of imipramine (AUC = 1966 ± 58.98 g/ml.h) was significantly ( < 0.0001) reduced by extract (AUC = 1228 ± 67.40 g/ml.h) and xylopic acid (AUC = 1250 ± 55.95 g/ml.h), while the AUC of xylopic acid (AUC = 968.10 ± 61.22 g/ml.h) was significantly ( < 0.0001) reduced by venlafaxine (AUC = 285.90 ± 51.92 g/ml.h) and fluoxetine (AUC = 510.60 ± 44.74 g/ml.h), possibly due to the effect of interfering agents on gastric emptying hence reducing oral absorption.
CONCLUSION
extract and xylopic acid interacted synergistically with imipramine, fluoxetine, and venlafaxine and reduced the systemic circulation of imipramine.

Satiation is the physiologic process that regulates meal size and termination, and it is quantified by the calories consumed to reach satiation. Given its role in energy intake, changes in satiation contribute to obesity's pathogenesis. Our study employed a protocolized approach to study the components of food intake regulation including a standardized breakfast, a gastric emptying study, appetite sensation testing, and a satiation measurement by an test. These studies revealed that satiation is highly variable among individuals, and while baseline characteristics, anthropometrics, body composition and hormones, contribute to this variability, these factors do not fully account for it. To address this gap, we explored the role of a germline polygenic risk score, which demonstrated a robust association with satiation. Furthermore, we developed a machine-learning-assisted gene risk score to predict satiation and leveraged this prediction to anticipate responses to anti-obesity medications. Our findings underscore the significance of satiation, its inherent variability, and the potential of a genetic risk score to forecast it, ultimately allowing us to predict responses to different anti-obesity interventions.
