BACKGROUND
Gastric per-oral endoscopic myotomy (G-POEM) is an innovative treatment that has become increasingly utilized for patients with refractory gastroparesis. The aim of this systematic review and meta-analysis was to evaluate the safety and effectiveness of G-POEM for the treatment of gastroparesis.
METHODS
Individualized search strategies were developed through February 2021 in accordance with the PRISMA and MOOSE guidelines. This meta-analysis was performed by calculating pooled proportions and mean difference preprocedure and postprocedure with rates estimated using random effects models. Measured outcomes included technical success, clinical success, improvement in gastroparesis cardinal symptom index (GCSI), change in gastric emptying rate, alterations in impedance planimetry (functional lumen imaging probe [FLIP]) assessment, and adverse events.
RESULTS
A total of 20 studies (n=797 patients; 67.41% female) were included. The mean age was 48.92±11.61 y, with an average duration of 4.24±1.11 y since gastroparesis diagnosis. Technical success was 98.47% [(95% CI: 97.14, 99.19);I2=0.00] with a mean myotomy length of 3.78±1.16 cm. In terms of clinical success, mean preprocedure GCSI scores were 3.38±0.37 and improved significantly postprocedure [weighted mean difference -1.56 (95% CI: -1.89 to -1.24); I2=82.53; P<0.001]. Gastric retention after 4 hours demonstrated ~50% improvement (preprocedure 43.08±9.24% versus postprocedure 22.97±10.19%; P<0.001). FLIP assessment with 40 mL and 50 mL balloons demonstrated a significant increase in diameter, distensibility index, and cross-sectional area postprocedure (all P<0.05). Procedure-associated adverse events occurred among 10.92% [(95% CI 5.09 to 19.32); I2=82.85] of patients.
CONCLUSION
G-POEM appears safe and highly effective for the treatment of patients with refractory gastroparesis regardless of symptom predominance or etiology.

Meta-Analysis
A systematic review meta-analysis and meta-regression on the implications of an aberrant right hepatic artery in patients undergoing pancreaticoduodenectomy for the treatment of malignant disease.
We investigated the outcomes of pancreaticoduodenectomy in the presence of an aberrant right hepatic artery (aRHA). We systematically reviewed Medline, Scopus, and Web of Science until April 2023 for studies comparing pancreaticoduodenectomy outcomes with and without aRHA. Endpoints included postoperative mortality, R0 resection margins, pancreatic fistulae, hemorrhage, biliary leak/fistulae, delayed gastric emptying, operative duration, and blood loss. Eight retrospective studies involving 1514 patients were included. The risk ratio (RR) for postoperative mortality and odds ratio (OR) for R0 resection between the aRHA and normal anatomy groups were 1.37 (95%CI:0.74-256) (I=0%, P=0.99) and 1.03 (95%CI:0.67-1.59) (I=10%, P=0.35). Besides a longer operative duration in the aRHA group, mean difference (MD) 54.64 (95% CI: 8.51-100.77) (I=94%, P<0.01), there were no significant differences in secondary endpoints. Meta-regression revealed a significant association between aRHA reconstruction and postoperative mortality (β=0.0179, P<0.01). This review displayed non-statistically significant differences in terms of surgical and oncological outcomes between patients with aRHA and patients with normal hepatic artery anatomy undergoing pancreaticoduodenectomy. However, the observed trend of increased postoperative mortality in patients with aRHA, combined with extended surgical duration and the link between aRHA reconstruction and postoperative mortality, prevents drawing definitive conclusions. Further research through high-quality studies is warranted.

Meta-Analysis
BACKGROUND
Functional dyspepsia (FD) refers to a group of clinical symptoms caused by gastric and duodenal dysfunction. Which is a chronic functional disorder of the gastrointestinal tract with no cure. Zhishixiaopi decoction (ZSXP) is a type of Chinese herbal prescription that for treating FD. Although some randomized controlled trials (RCTs) report that ZSXP can significantly improve FD clinical symptoms and/or laboratory results, the trial design varies greatly among studies, making it challenging to draw a conclusion of the efficacy of ZSXP in treating FD.
DESIGN
A systematic review and a meta-analysis.
SETTING
Mianyang Central Hospital.
OBJECTIVE
We conducted a systematic review and a meta-analysis to evaluate the efficacy and safety of ZSXP for treating FD.
METHODS
We developed inclusion and exclusion criteria based on FD diagnosed criteria, interventions to treat FD, and outcomes of these interventions. Search strategies combined disease terms, symptom terms, anatomy terms and intervention terms. Literature search was conducted on eight online databases in English or Chinese, including Medline (via PubMed), Embase (via Ovid), The Cochrane Library, Web of Science, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), Chinese Scientific Journals Database (VIP), and Wanfang Database.
INTERVENTION
The experimental group received oral administration of ZSXP and had a complete treatment process. ZSXP needs to fully contain the key herbal ingredients, regardless of whether the dosage of each herb is consistent with the original prescription. The Control group received monotherapy or combination therapy of other Western medicine and had a complete treatment process.
OUTCOMES
The primary outcomes appraised were Total effective rate (TER), serum levels of Motilin(MOT), Gastrin(GAS) and Somatostatin (SS), Gastric emptying rate (GER) using a Barium meal method (GER(B)) and Gastric half emptying time using an Ultrasonic method (GHET(T1/2)). The Cochrane Bias Risk Tool was used for quality critical appraisal, Review Manager (RevMan) version 5.3 was used for statistical analysis.
RESULTS
A total of 21 medium-quality RCTs were included in the meta-analysis. All 21 included studies were conducted and completed in Mainland China from 1998 to 2020. The treatment duration was between two weeks to two months. The meta-analysis suggests that, compared with the Western medicine treatment group, ZSXP treatment was more effective to improving the TER in FD [Odds ratio, OR = 3.54, 95%CI:(2.49, 5.05), Z = 6.99, P<0.00001] without significant increase in adverse events. However, no statistical significance was found between the groups in serum MOT levels [Standard mean difference, SMD = 1.05, 95%CI:(-0.42, 2.53), Z = 1.04, P = 0.16], serum GAS levels [SMD = -0.16, 95%CI:(-1.20, 0.88), Z = 0.31, P = 0.76], serum SS levels [SMD = -0.04, 95%CI:(-1.97, 1.89), Z = 0.04, P = 0.97], GER(B) [SMD = 1.09, 95%CI:(-0.81, 3.00), Z = 1.12, P = 0.26]or GHET(T1/2) [Mean difference, MD = -2.18, 95%CI:(-5.55, 1.19), Z = 1.27, P = 0.20].
CONCLUSIONS
The meta-analysis suggests that Zhishixiaopi treatment is a relatively effective and safe traditional Chinese medicine prescription and could be used for functional dyspepsia treatment. Considering the limitations of this study, the conclusion needs to be further confirmed by high-quality, multi-center, and large-sample randomized controlled trials.

Meta-Analysis Review
Pedicled ligament flaps during pancreatoduodenectomy are associated with reduced hemorrhage from hepatic artery and gastroduodenal artery stump during pancreatoduodenectomy: a systematic review, meta-analysis and trial sequential analysis.
BACKGROUND
The aim of this study was to investigate whether pedicled ligament flaps (PLF) covering around the hepatic and gastroduodenal artery stump can provide better clinical outcomes in pancreatoduodenectomy (PD).
METHODS
We conducted a comprehensive search of databases (inception to January 2023) to identify studies comparing PD with or without PLF covering the skeletonized arteries. The perioperative and postoperative outcomes were compared. Pooled odds ratios (ORs) with 95 % confidence intervals (CIs) were calculated using fixed-effects models.
RESULTS
Ten studies were included in the qualitative synthesis. Six studies with 3538 patients met the inclusion criteria for the meta-analysis. Patients in the PLF group had a significantly lower rate of PPH from the hepatic artery or gastroduodenal artery stump (H/G PPH) (OR: 0.41; 95 % CI, 0.22-0.75; P < 0.01) and overall PPH (OR: 0.65; 95 % CI, 0.46-0.93; P = 0.02). There were no significant differences between the two groups in terms of morbidity, grade B/C postoperative pancreatic fistula (B/C POPF), delayed gastric emptying (DGE), reoperation, or mortality.
CONCLUSION
Prophylactic pedicled ligament flaps covering around the skeletonized arteries significantly reduced overall PPH and H/G PPH, and it seemed to have no obvious influence on other complications.

Review
Cancer pain is one of the most disabling symptoms complained by cancer patients, with a crucial impact on physical and psychological well-being. Botulinum neurotoxins (BoNTs) type A and B have emerged as potential interventions for chronic pain; however, their role in these patients is still debated. Thus, this systematic review of randomized controlled trials aimed at assessing the effects of BoNT treatment for cancer pain to guide physicians in an evidence-based approach integrating BoNT in cancer care. Out of 5824 records, 10 RCTs satisfied our eligibility criteria and were included in the present work for a total of 413 subjects with several cancer types (breast, head and neck, esophageal, and thoracic/gastric cancers). While some studies demonstrated significant pain reduction and improved quality of life post-BoNT-A injections, outcomes across different cancer types were inconclusive. Additionally, several effects were observed in functioning, dysphagia, salivary outcomes, esophageal strictures, gastric emptying, and expansions. This review emphasizes the need for further standardized research to conclusively establish the efficacy of BoNT in comprehensive cancer pain management.

Meta-Analysis Review
BACKGROUND
The effects of gastric electrical stimulation are not fully understood. We aimed to assess the efficacy of gastric electrical stimulation (GES) for patients with gastroparesis and gastroparesis-like symptoms.
MATERIALS AND METHODS
We searched PubMed, Scopus, Cochrane, Web of Science, Embase, and Science Direct to identify controlled trials and cohort studies. We used random effects models to estimate pooled effects. A total of nine studies met the criteria and were included for the final qualitative synthesis and the quantitative analysis. We examined the mean absolute differences (MD) and 95% CIs.
RESULTS
Nine studies (n = 730) met the criteria and were included for the final qualitative synthesis and the quantitative analysis. There was significant improvement in gastrointestinal (GI) total symptom score (TSS) with the GES group compared with controls during the randomized blind trials. This effect was sustained at 12 months after treatment compared with before treatment (MD = -6.07; 95% CI, -4.5 to -7.65; p < 0.00001). The pooled effect estimate showed a significant improvement in frequency of weekly vomiting episodes at 12 months compared with before treatment (MD = -15.59; 95% CI, -10.29 to -20.9; p < 0.00001).
CONCLUSION
GES appears beneficial, with significant improvement in GI TSS, weekly vomiting frequency, gastric emptying study, and quality of life.

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.

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.

Meta-Analysis
BACKGROUND
Diabetic gastroparesis is a common complication in patient with diabetes. Dietary intervention has been widely used in the treatment of diabetic gastroparesis. The aim of this study is to evaluate the role of diet in the treatment of diabetic gastroparesis.
METHODS
This systematic review was conducted a comprehensive search of randomized controlled trials using dietary interventions for the treatment of diabetic gastroparesis up to 9 November 2023. The primary outcomes were gastric emptying time and clinical effect, while fasting blood glucose, 2-hour postprandial blood glucose and glycosylated hemoglobin were secondary outcomes. Data analysis was performed using RevMan 5.4 software, and publication bias test was performed using Stata 15.1 software.
RESULTS
A total of 15 randomized controlled trials involving 1106 participants were included in this review. The results showed that patients with diabetic gastroparesis benefit from dietary interventions (whether personalized dietary care alone or personalized dietary care+routine dietary care). Compared with routine dietary care, personalized dietary care and personalized dietary care+routine dietary care can shorten the gastric emptying time, improve clinical efficacy, and reduce the level of fasting blood glucose, 2-hour postprandial blood glucose and glycosylated hemoglobin.
CONCLUSIONS
Limited evidence suggests that dietary intervention can promote gastric emptying and stabilize blood glucose control in patients with diabetic gastroparesis. Dietary intervention has unique potential in the treatment of diabetic gastroparesis, and more high-quality randomized controlled trials are needed to further validate our research results.

Meta-Analysis
AIMS
To evaluate short-term clinical and long-term survival outcomes of pancreatic resection for pancreatic metastasis from renal cell carcinoma (RCC).
METHODS
A retrospective evaluation of patients undergoing pancreatic resection for metastasis from RCC over a 12-years period was conducted. Furthermore, a systematic search of electronic data sources and bibliographic reference lists were conducted to identify studies investigating the same clinical question. Short-term clinical and long-term survival outcomes were evaluated. Kaplan-Meier survival plots were constructed for survival outcomes. Cox-proportional regression analysis was performed to determine factors associated with survival. Finally, meta-analysis of survival outcomes was conducted using random-effects modelling.
RESULTS
Eighteen patients underwent pancreatic resections for RCC pancreatic metastasis within the study period. The mean age of the included patients was 63.8 ± 8.0 years. There were 10(55.6 %) male and 8(44.4 %) female patients. Pancreatectomy was associated with 4(25.0 %) Clavien-Dindo (C-D) I, 5(31.3 %) C-D II, and 7(43.7 %) C-D III complications, 7(38.8 %) pancreatic fistula, 3(16.7 %) post-pancreatectomy acute pancreatitis, 1(5.6 %) delayed gastric emptying, and 1(5.6 %) chyle leak. The mean length of hospital stay was 18 ± 16.3 days. The median survival was 64 months (95 % CI 60-78). The 3-and 5-year disease-free survival rates were 83.3 % and 55.5 %, respectively. The 3-and 5-year survival rates were 100 % and 55.6 %, respectively. The pooled analyses of 553 patients demonstrated 3-and 5-year survival rates of 77.6 % and 60.7 %, respectively.
CONCLUSIONS
Pancreatectomy for RCC metastasis is associated with acceptable short-term clinical and promising long-term survival outcomes. Considering the rarity of the entity, escalation of level of evidence in this context is challenging.
