Abstract
The efficacy of preoperative treatment for pancreatic cancer (PC) has been reported in randomized controlled trials, but the optimal regimen and the appropriateness of combining radiotherapy remain controversial. Therefore, predicting the efficacy of preoperative treatment using biomarkers and determining whether to combine chemotherapy or radiotherapy based on the biology of individual tumors could help personalize treatment and maximize therapeutic outcomes. In this study, a microRNA (miRNA) microarray analysis was performed using peripheral blood plasma exosomes from 10 PC patients who underwent neoadjuvant chemoradiotherapy, leading to the identification of miR-6855-5p as a candidate miRNA. miR-6855-5p was found to induce radioresistance in PC cells. In another cohort of 28 patients, it was observed that those with higher expression levels of miR-6855-5p in peripheral blood plasma exosomes tended to have increased radioresistance (r = - 0.5964). In future, measuring plasma exosomal miR-6855-5p before treatment could potentially lead to precision medicine by personalizing the decision of whether to include radiotherapy in the treatment plan.

Preoperative nutritional status is a useful predictor of the feasibility of postoperative treatment in octogenarian-plus pancreatic ductal adenocarcinoma patients. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108650.

Abstract
BACKGROUND The suitability of radical surgery for very elderly pancreatic cancer (PC) patients remains controversial due to concerns about postoperative functional reserve. Inflammatory-nutritional status may help identify elderly patients at risk of compromised postoperative treatment tolerance. METHODS This retrospective analysis included 121 patients over eighty who were diagnosed with PC in 2010-2019, 40 of whom underwent radical surgery. Surgical outcomes were compared with those of 205 younger patients (under 80 years-old) who underwent radical surgery. K-means cluster analysis was conducted with four inflammatory-nutritional indices (NLR, PLR, PNI, and mGPS) to define, and the indices using ordinal logistic analysis were evaluated in each cluster to create a formula named 'nutritional index (NTI)', which was then used to redefine the clusters. The predictive ability of the NTI was validated in other octogenarians who underwent pancreatectomy for PC between 2020 and 2023. RESULTS Patients older than eighty exhibited comparable overall survival to younger patients (median survival time, 30.7/37.1 months, p = 0.20). However, octogenarian-plus patients had lower rates of adjuvant chemotherapy (AC) initiation (45/80 %) and treatment upon recurrence (52/84 %), resulting in shorter survival after recurrence (7.4/11.1 months, p = 0.06). Inflammatory-nutritional status was significantly associated with overall survival, with poor nutritional status being linked to lower rates of AC initiation and/or treatment upon recurrence. NTI effectively predicted AC feasibility. CONCLUSIONS Radical surgery for octogenarian-plus PC patients meeting the current criteria was safe, but lower rates of postoperative treatment initiation may lead to poorer outcomes after recurrence. Inflammatory-nutritional status assessment could enhance surgical eligibility in octogenarian-plus PC patients.

Abstract
BACKGROUND/OBJECTIVES MicroRNAs (miRNAs) are involved in chemosensitivity through their biological activities in various malignancies, including pancreatic cancer (PC). However, single-miRNA models offer limited predictability of treatment response. We investigated whether a multiple-miRNA prediction model optimized via machine learning could improve treatment response prediction. METHODS A total of 20 and 66 patients who underwent curative resection for PC after gemcitabine-based preoperative treatment were included in the discovery and validation cohorts, respectively. Patients were classified according to their response to preoperative treatment. In the discovery cohort, miRNA microarray and machine learning were used to identify candidate miRNAs (in peripheral plasma exosomes obtained before treatment) associated with treatment response. In the validation cohort, miRNA expression was analyzed using quantitative reverse transcription polymerase chain reaction to validate its ability to predict treatment response. RESULTS In the discovery cohort, six and three miRNAs were associated with good and poor responders, respectively. The combination of these miRNAs significantly improved predictive accuracy compared with using each single miRNA, with area under the curve (AUC) values increasing from 0.485 to 0.672 to 0.909 for good responders and from 0.475 to 0.606 to 0.788 for poor responders. In the validation cohort, improved predictive performance of the miRNA combination over single-miRNA prediction models was confirmed, with AUC values increasing from 0.461 to 0.669 to 0.777 for good responders and from 0.501 to 0.556 to 0.685 for poor responders. CONCLUSIONS Peripheral blood miRNA profiles using an optimized combination of miRNAs may provide a more advanced prediction model for preoperative treatment response in PC.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) has a high recurrence rate even after radical resection because of subclinical tumors. To manage them, a reliable biomarker that can indicate the presence of subclinical tumors and predict their chemosensitivity is required. This study aimed to identify a miRNA as a biomarker that can be used to individualize postoperative adjuvant chemotherapy using postoperative peripheral blood samples. Integrating miRNA microarray data from the blood of 18 patients with PDAC and the in vitro results regarding the phenotypes of chemoresistant PDAC cells, a candidate miRNA was identified. The relationships between candidate miRNA expression and chemosensitivity were examined in vitro and in clinical samples from other cohorts of 33 patients with recurrence. Comprehensive analyses of blood samples detected 5 candidate miRNAs. Of these, miR-26a-5p was considered a candidate biomarker of chemosensitive phenotypes. In validation experiments, chemosensitivity was inversely correlated with miR-26a-5p expression in vitro. Moreover, the ability of miR-26a-5p to predict chemosensitivity was clinically evaluated using blood samples. Patients with high miR-26a-5p expression in the blood after radical resection exhibited a significantly longer survival time after recurrence. Thus, we concluded that miR-26a-5p is a potentially useful biomarker for managing patients with PDAC, especially those undergoing adjuvant chemotherapy.

Abstract
BACKGROUND Whether radiation should be added to neoadjuvant treatment remains controversial, and liquid biopsy has not been reported to predict radioresistance in pancreatic cancer (PC). We aimed to identify microRNAs (miRNAs) governing radioresistance in PC by utilizing peripheral plasma exosome samples and to verify their usefulness as biomarkers. METHODS miRNA microarray analysis was conducted using pretreatment peripheral plasma exosomes from 10 patients with PC receiving neoadjuvant chemoradiotherapy (NACRT) in the discovery cohort. Patients were categorized into two groups (good and poor responders) based on treatment responses, and candidate miRNAs exhibiting differential expression between the two groups were identified. The radiosensitivity of PC cells was examined after miR-6855-5p overexpression. Next-generation sequencing (NGS) and TargetScan were used to explore the mechanisms of radioresistance. We investigated the correlation between miR-6855-5p expression levels in the pretreatment peripheral plasma exosomes of 28 patients in the validation cohort and the response to NACRT. RESULTS miR-6855-5p expression was higher in poor responders than in good responders. miR-6855-5p induces radioresistance in PC cells. NGS showed that epithelial-mesenchymal transition (EMT) was involved in miR-6855-5p-related radioresistance. Forkhead box protein A1 (FOXA1) was identified as a direct target of miR-6855-5p using NGS and TargetScan. Clinical examination of samples from the validation cohort revealed a tendency for patients with higher expression of miR-6855-5p in peripheral plasma exosomes to exhibit increased radioresistance (r = -0.5964). CONCLUSIONS miR-6855-5p regulates the radioresistance of PC by inducing EMT via suppressing FOXA1, and miR-6855-5p in peripheral plasma exosomes may be a biomarker for radioresistance of PC.

Ann Gastroenterol Surg 2024; 8:868-876.

Abstract
Purpose Postoperative venous thromboembolism (VTE) risk is pronounced after abdominal cancer surgery. Enoxaparin shows promise in preventing VTE in gastrointestinal, gynecological, and urological cancers, but its application after surgery for hepatobiliary-pancreatic malignancy has been under-evaluated due to bleeding concerns. We confirmed the safety of enoxaparin administration in patients undergoing curative hepatobiliary-pancreatic surgery for malignancies in a prospective, multi-center, phase I study. Methods The study was conducted from April 2015 to May 2021 across eight specialized centers. Patients (n = 262) were randomized to enoxaparin prophylaxis given postoperatively for 8 days (n = 131) or control (n = 131). The primary endpoint was the efficacy in reducing VTE. Secondary endpoints examined safety. Results The full analysis set included 259 patients (131 control, 129 enoxaparin). The per-protocol population included 233 patients (117 control, 116 enoxaparin). Most cases were hepatic malignancies (111 control, 111 enoxaparin). The median administration duration of enoxaparin was 7 days, with 92% receiving 4000 units/day. Despite a reduction in the relative risk (RR) of VTE due to postoperative enoxaparin administration, the results were not significant (control: four cases, 3.4% vs. treatment: two cases, 1.7%; RR 0.50, 95% CI 0.09-2.70; p = 0.6834). No significant difference was found in the incidence of bleeding events (control: five cases, 4.3% vs. treatment: five cases, 4.3%, RR 1.00, 95% CI 0.53-1.89; p = 1.0000). Conclusions The perioperative administration of enoxaparin in hepatobiliary-pancreatic malignancies is feasible and safe. However, further case accumulation and investigation are necessary to assess its potential in reducing the occurrence of VTE.

Abstract
BACKGROUND Surgical site infections (SSIs) are common complications after abdominal surgery. AIM To compare which suture devices could reduce the incidence of incisional surgical site infections (SSIs) after gastrointestinal surgery using a systematic review and network meta-analysis. METHODS The CENTRAL, PubMed, and ICHUSHI-Web databases were searched from January 1st, 2000, to December 31st, 2022, for randomized clinical trials (RCTs) comparing the incidence of incisional SSI after gastrointestinal surgery among patients treated with different surgical suture devices, including non-absorbable sutures, absorbable sutures, skin staplers, and tissue adhesives (last searched in August 23th, 2023). The risk of bias was assessed using the criteria of the Cochrane Handbook for Systematic Reviews of Interventions. To estimate the pooled odds ratios (ORs) for each comparison, a fixed-effect inverse-variance model based on the Mantel-Haenszel approach was employed. FINDINGS A total of 18 RCTs with 5496 patients were included in this study. The overall SSIs in absorbable sutures were significantly lower than those in skin staplers (OR: 0.77; 95% confidence intervals (CI): 0.63-0.95) and non-absorbable sutures (OR: 0.62; 95% CI: 0.39-0.99), whereas SSIs in absorbable sutures were not significantly different from the SSIs in tissue adhesive. The highest P-score was 0.91 for absorbable sutures. A funnel plot for estimating the heterogeneity of the studies revealed that a publication bias would be minimal (Egger test, P = 0.271). CONCLUSION This study showed that absorbable sutures reduced incisional SSIs in gastrointestinal surgical operations compared to any other suture devices.

Abstract
Anti-FGFR treatment for cholangiocarcinoma (CCA) with fibroblast growth factor receptor (FGFR) alteration is a promising treatment option. Since the antitumor mechanisms of anti-FGFR inhibitors and conventional cytotoxic drugs differ, synergistic effects can be possible. This study aimed to evaluate the efficacy of the combined administration of gemcitabine (GEM) and pemigatinib in CCA cells with FGFR2 alterations. To simulate the treatment for patients with 3 kinds of CCA, chemonaïve CCA with activation of the FGF pathway, chemo-resistant CCA with activation of the FGF pathway, and CCA without FGF pathway activation (as controls), we evaluated 3 different CCA cell lines, CCLP-1 (with a FGFR2 fusion mutation), CCLP-GR (GEM-resistant cells established from CCLP-1), and HuCCT1 (without FGFR mutations). There was no significant difference between CCLP-1 and HuCCT1 in GEM suspensibility (IC50 = 19.3, 22.6 mg/dl, p = 0.1187), and the drug sensitivity to pemigatinib did not differ between CCLP-1 and CCLP-GR (IC50 = 7.18,7.60 nM, p = 0.3089). Interestingly, only CCLP-1 showed a synergistic effect with combination therapy consisting of GEM plus pemigatinib in vitro and in vivo. In a comparison of the reaction to GEM exposure, only CCLP-1 cells showed an increase in the activation of downstream proteins in the FGF pathway, especially FRS2 and ERK. In association with this reaction, cell cycle and mitosis were increased with GEM exposure in CCLP-1, but HuCCT1/CCLP-GR did not show this reaction. Our results suggested that combination therapy with GEM plus pemigatinib is a promising treatment for chemonaïve patients with CCA with activation of the FGF pathway.

Abstract
AIM Tumor Ki-67 expression reflects prognosis and cancer grade, and biopsy-based preoperative assessment of Ki-67 expression is key to treatment. Apparent diffusion coefficient (ADC) values obtained with this imaging may noninvasively predict Ki-67 by reflecting tumor cell density and limited water molecule movement from irregular alignment. This study aimed to investigate the ability of ADC values to predict Ki-67 expression in intrahepatic cholangiocarcinoma (ICC). METHOD We retrospectively analyzed 39 cases of ICC confirmed by surgical pathology. All patients had undergone magnetic resonance imaging, and ADC values (mean, minimum, and maximum) were calculated. Ki-67 expression was assessed by immunohistochemistry, and patients were divided into groups of high (n = 18) and low (n = 21) Ki-67 expression. To assess the diagnostic performance of the ADC values for Ki-67 expression, we used the receiver operating characteristic curve and compared the areas under the curve (AUC). RESULTS The mean and minimum ADC values were significantly lower in the group with high Ki-67 expression. For predicting high Ki-67 expression, the AUC values were 0.701 for mean ADC, 0.818 for minimum ADC, and 0.571 for maximum ADC. The diagnostic sensitivity and specificity of the minimum ADC values were 88.9% and 76.2%, respectively. In addition, with ADC values combined, the AUC increased to 0.831. Apparent diffusion coefficient is a useful predictor of Ki-67 expression level in ICC. CONCLUSION Apparent diffusion coefficient values, especially minimum ADC values, can noninvasively predict ICC associated with high Ki-67 expression.

Abstract
BACKGROUND The optimal neoadjuvant chemotherapy (NAC) regimen for patients with localized pancreatic ductal adenocarcinoma (PDAC) remains uncertain. This trial aimed to evaluate the efficacy and safety of two neoadjuvant chemotherapy (NAC) regimens, gemcitabine plus nab-paclitaxel (GA) and gemcitabine plus S-1 (GS), in patients with resectable/borderline-resectable (R/BR) PDAC. PATIENTS AND METHODS Treatment-naïve patients with R/BR-PDAC were enrolled and randomly allocated. They received two cycles (2 months) of each standard protocol, followed by radical surgery for those without tumor progression in general hospitals belonging to our intergroup. The primary endpoint was to determine the superior regimen on the basis of achieving a 10% increase in the rate of patients with progression-free survival (PFS) at 2 years from allocation. RESULTS A total of 100 patients were enrolled, with 94 patients randomly assigned to the GS arm (N = 46) or GA arm (N = 48). The 2-year PFS rates did not show the stipulated difference [GA, 31% (24-38%)/GS, 26% (18-33%)], but the Kaplan-Myer analysis showed significance (median PFS, GA/GS 14 months/9 months, P = 0.048; HR 0.71). Secondary endpoint comparisons yielded the following results (GA/GS arm, P-value): rates of severe adverse events during NAC, 73%/78%, P = 0.55; completion rates of the stipulated NAC, 92%/83%, P = 0.71; resection rates, 85%/72%, P = 0.10; average tumor marker (CA19-9) reduction rates, -50%/-21%, P = 0.01; average numbers of lymph node metastasis, 1.7/3.2, P = 0.04; and median overall survival times, 42/22 months, P = 0.26. CONCLUSIONS This study found that GA and GS are viable neoadjuvant treatment regimens in R/BR-PDAC. Although the GA group exhibited a favorable PFS outcome, the primary endpoint was not achieved.

Updated evidence of the effectiveness and safety of transanal drainage tube for the prevention of anastomotic leakage after rectal low anterior resection: a systematic review and meta-analysis. Tech Coloproctol 2024; 28:71. [PMID: 38916755 DOI: 10.1007/s10151-024-02942-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Accepted: 05/15/2024] [Indexed: 06/26/2024]
Abstract
BACKGROUNDS Anastomotic leakage (AL) represents a major complication after rectal low anterior resection (LAR). Transanal drainage tube (TDT) placement offers a potential strategy for AL prevention; however, its efficacy and safety remain contentious. METHODS A systematic review and meta-analysis were used to evaluate the influence of TDT subsequent to LAR as part of the revision of the surgical site infection prevention guidelines of the Japanese Society of Surgical Infectious Diseases (PROSPERO registration; CRD42023476655). We searched each database, and included randomized controlled trials (RCTs) and observational studies (OBSs) comparing TDT and non-TDT outcomes. The main outcome was AL. Data were independently extracted by three authors and random-effects models were implemented. RESULTS A total of three RCTs and 18 OBSs were included. RCTs reported no significant difference in AL rate between the TDT and non-TDT groups [relative risk (RR): 0.69, 95% confidence interval (CI) 0.42-1.15]. OBSs reported that TDT reduced AL risk [odds ratio (OR): 0.45, 95% CI 0.31-0.64]. In the subgroup excluding diverting stoma (DS), TDT significantly lowered the AL rate in RCTs (RR: 0.57, 95% CI 0.33-0.99) and OBSs (OR: 0.41, 95% CI 0.27-0.62). Reoperation rates were significantly lower in the TDT without DS groups in both RCTs (RR: 0.26, 95% CI 0.07-0.94) and OBSs (OR: 0.40, 95% CI 0.24-0.66). TDT groups exhibited a higher anastomotic bleeding rate only in RCTs (RR: 4.28, 95% CI 2.14-8.54), while shorter hospital stays were observed in RCTs [standard mean difference (SMD): -0.44, 95% CI -0.65 to -0.23] and OBSs (SMD: -0.54, 95% CI -0.97 to -0.11) compared with the non-TDT group. CONCLUSIONS A universal TDT placement cannot be recommended for all rectal LAR patients. Some patients may benefit from TDT, such as patients without DS creation. Further investigation is necessary to identify the specific beneficiaries.

Abstract
BACKGROUND High skeletal muscle mass might be a prognostic factor for patients with pancreatic ductal adenocarcinoma (PDAC); however, the underlying reason is unclear. We hypothesized that myokines, which are cytokines secreted by the skeletal muscle, function as suppressors of PDAC. We specifically examined irisin, a myokine, which plays a critical role in the modulation of metabolism, to clarify the anticancer mechanisms. METHODS First, the effect of the conditioned medium (CM) from skeletal muscle cells and from irisin-knockdown skeletal muscle cells on PDAC cell lines was evaluated. We then investigated the effects and anticancer mechanism of irisin in PDAC cells, and evaluated the anticancer effect of recombinant irisin in a PDAC xenograft mouse model. Finally, patients undergoing pancreatic resection for PDAC were divided into two groups based on their serum irisin level, and the long-term outcomes were evaluated. RESULTS The CM enhanced gemcitabine sensitivity by inducing apoptosis and decreasing cell migration by inhibiting epithelial-mesenchymal transition (EMT) in PDAC cell lines. The CM derived from irisin-knockdown skeletal muscle cells did not affect the PDAC cell lines. The addition of recombinant irisin to PDAC cell lines facilitated sensitivity to gemcitabine by inhibiting the mitogen-activated protein kinase (MAPK) pathway, and decreased migration by inhibiting EMT via the transforming growth factor-β/SMAD pathway. Xenografts injected with gemcitabine and recombinant irisin grew slower than the xenografts injected with gemcitabine alone. The overall survival was prolonged in the high-irisin group compared with that in the low-irisin group. CONCLUSIONS Skeletal muscle-derived irisin may affect PDAC by enhancing its sensitivity to gemcitabine and suppressing EMT.

Abstract
Tumor endothelial cells (TECs), which are thought to be structurally and functionally different from normal endothelial cells (NECs), are increasingly attracting attention as a therapeutic target in hypervascular malignancies. Although colorectal liver metastasis (CRLM) tumors are hypovascular, inhibitors of angiogenesis are a key drug in multidisciplinary therapy, and TECs might be involved in the development and progression of cancer. Here, we analyzed the function of TEC in the CRLM tumor microenvironment. We used a murine colon cancer cell line (CT26) and isolated TECs from CRLM tumors. TECs showed higher proliferation and migration than NECs. Coinjection of CT26 and TECs yielded rapid tumor formation in vivo. Immunofluorescence analysis showed that coinjection of CT26 and TECs increased vessel formation and Ki-67+ cells. Transcriptome analysis identified kallikrein-related peptide 10 (KLK10) as a candidate target. Coinjection of CT26 and TECs after KLK10 downregulation with siRNA suppressed tumor formation in vivo. TEC secretion of KLK10 decreased after KLK10 downregulation, and conditioned medium after KLK10 knockdown in TECs suppressed CT26 proliferative activity. Double immunofluorescence staining of KLK10 and CD31 in CRLM tissues revealed a significant correlation between poor prognosis and positive KLK10 expression in TECs and tumor cells. On multivariate analysis, KLK10 expression was an independent prognostic factor in disease-free survival. In conclusion, KLK10 derived from TECs accelerates colon cancer cell proliferation and hematogenous liver metastasis formation. KLK10 in TECs might offer a promising therapeutic target in CRLM.

Geriatric prognostic scoring system predicts survival after hepatectomy for elderly patients with liver cancer. Ann Gastroenterol Surg 2024; 8:498-506. [PMID: 38707235 PMCID: PMC11066489 DOI: 10.1002/ags3.12762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 10/30/2023] [Accepted: 11/27/2023] [Indexed: 05/07/2024] Open
Abstract
Aim The number of elderly patients with liver cancer is increasing with the aging society. The Geriatric Prognostic Scoring System is useful in predicting the postoperative prognosis for elderly patients with gastrointestinal cancer. The aim of the present study was to assess the predictive ability of the geriatric prognostic scoring system for postoperative survival in elderly patients with liver cancer. Methods Eighty-eight patients aged ≥75 years who were treated for primary liver cancer and metastatic liver tumor were retrospectively analyzed. The Geriatric Prognostic Score (GPS) was created by several clinical parameters such as age, sex, type of cancer, stage, performance status, body mass index, and comprehensive geriatric assessment. Each patient was divided into two groups of high-risk to low-risk according to their GPS: ≧30 high-risk group and <30 low-risk. The predictive ability of geriatric prognostic scoring system for postoperative survival was assessed in univariate and multivariate analyses. Results Of the 88 patients, 75 were diagnosed as hepatocellular carcinoma and 13 as colorectal liver metastasis. After geriatric prognostic scoring system assessments, 26 patients were diagnosed as high-risk and the remaining 62 as low-risk. The 3-year overall survival rates were 78.5% in the low-risk group and 35.1% in the high-risk group (p < 0.001). The univariate and multivariate analyses of overall survival identified high GPS as an independent significant factor (p < 0.001). Conclusions We could conclude that the geriatric prognostic scoring system is useful in predicting patients' prognosis after hepatectomy and it can provide helpful information to surgeons for determining treatment strategies for elderly patients with liver cancer.

Abstract
Although single-incision laparoscopic surgery (SILS) has gained some attention as a feasible alternative to conventional multiport laparoscopic surgery (MPLS) in colonic surgery, it became less prevalent than expected. Hence, we conducted this systematic review to evaluate the feasibility, safety, and oncological outcomes of single-incision laparoscopic colectomy (SILC) with meta-analysis and discussion of the future prospect of SILS. The search was conducted from September to October 2023 using PubMed and the Cochrane Central Register of Controlled Trials. Articles on colorectal cancer comparing SILC with multiport laparoscopic colectomy (MPLC) from all randomized controlled trials and comparative studies with 50 patients or more per arm were examined. The primary outcomes were the intra- and postoperative complication rates, and the secondary outcomes were the perioperative and oncological outcomes. The trends of the SILS number in Japan and the trends of the number of articles on SILS in PubMed were also reviewed. There were no significant differences in perioperative complication rates, operative factors, and oncological outcomes between SILC and MPLC, although heterogeneity was observed mainly in operative factors and the total length of the skin incision was significantly shorter in SILC. Therefore, SILC is technically and oncologically feasible and safe when performed by experienced laparoscopic surgeons. The case number of SILS was gradually increasing but the rate of SILS was decreasing in Japan. The number of articles on SILS was also decreasing. SILS has gained foothold to some extent but has plateaued. The emerging new robotic platform may reappraise the concept of SILS.

Abstract
The aim of this study was to conduct a systematic review and meta-analysis of the efficacy of fascial closure using antimicrobial-sutures specifically for the prevention of surgical site infections (SSIs) in gastrointestinal surgery, as part of the revision of the SSI prevention guidelines of the Japanese Society of Surgical Infectious Diseases (JSSI). We searched CENTRAL, PubMed and ICHUSHI-Web in May 2023, and included randomized controlled trials (RCTs) comparing antimicrobial-coated and non-coated sutures for fascial closure in gastrointestinal surgery (PROSPERO No. CRD42023430377). Three authors independently screened the RCTs. We assessed the risk of bias and the GRADE criteria for the extracted data. The primary outcome was incisional SSI and the secondary outcomes were abdominal wall dehiscence and the length of postoperative hospital stay. This study was supported partially by the JSSI. A total of 10 RCTs and 5396 patients were included. The use of antimicrobial-coated sutures significantly lowered the risk of incisional SSIs compared with non-coated suture (risk ratio: 0.79, 95% confidence intervals: 0.64-0.98). In subgroup analyses, antimicrobial-coated sutures reduced the risk of SSIs for open surgeries, and when monofilament sutures were used. Antimicrobial-coated sutures did not reduce the incidence of abdominal wall dehiscence and the length of hospital stay compared with non-coated sutures. The certainty of the evidence was rated as moderate according to the GRADE criteria, because of risk of bias. In conclusion, the use of antimicrobial-coated sutures for fascial closure in gastrointestinal surgery is associated with a significantly lower risk of SSI than non-coated sutures.

Abstract
BACKGROUND According to the sixth Gastric Cancer Treatment Guideline, the regimen included nab-paclitaxel(nab-PTX) is a conditional recommendation as second-line treatment for advanced gastric cancer. However, the selection criteria of nab-PTX is not clear. METHOD Questionnaire survey as narrative approach on the problems of paclitaxel premedication, the symptoms due to paclitaxel containing alcohol, and infusion time was conducted for patients who had been treated with paclitaxel. RESULTS Thirty-six patients answered the questionnaire. Nonelderly patients(<65 years)or patients without comorbid medications complained of dissatisfaction with the inconvenience due to premedication significantly more than elderly patients(≥65 years)or patients with comorbid medications. Females or nonelderly patients were significantly more troubled by sleepiness due to premedication than males or elderly patients. Eight out of 11 patients who had visited hospital by driving a car for first-line treatment were troubled by prohibition of driving on the day of treatment. Thirty out of 36 patients answered that they would feel benefits from 30-minutes shortening of infusion time. CONCLUSION Questionnaire survey suggests that we may select the patients for nab-PTX properly by clarifying the inconvenience of daily life associated with premedication, the way of transportation for visiting hospital, and the benefits by shortening of infusion time.

Abstract
BACKGROUND The actual situation of oral care and oral troubles for patients with gastric cancer received chemotherapy is not clear. METHODS Questionnaire survey in the form of oral questions was performed for patients with gastric cancer who received chemotherapy from December 2021 to February 2022. The relevance between the survey results and background factors was examined using the χ2 test. RESULTS We performed the questionnaire survey for 36 patients. Of the 36 patients, 29 patients received dental check-up before starting chemotherapy. Fourteen of the 29 patients(48%)continued the dental check-up. Of 14 patients who continued the dental check-up, 9 patients were 65 years or older, while 14 of 15 patients who discontinued the dental check-up were 65 years or older. Continuity of dental check-up was low among the elderly patients. The rate of dysgeusia were 78 vs 30% in the patients who adopted and who did not adopt oral care other than toothbrushing(p=0.01). The frequency of oral troubles was dysgeusia(47%), stomatitis(42%), and dry mouth(36%). The severity of the oral troubles was, in order, dysgeusia, dry mouth, and pain. The most common side effect due to chemotherapy causing decreased food intake was dysgeusia. CONCLUSIONS Dysgeusia was the most frequent and severe oral trouble.

Abstract
OBJECTIVE Percutaneous transhepatic gallbladder aspiration (PTGBA) and/or drainage (PTGBD) are useful approaches in the management of acute cholecystitis in patients who cannot tolerate surgery because of poor general condition or severe inflammation. However, reports regarding its effect on the surgical outcomes of subsequent laparoscopic cholecystectomy (LC) are sparse. The aim of this retrospective study was to investigate the influence of PTGBA on surgical outcomes of subsequent LC by comparing the only-PTGBA group, including patients who did not need the additional-PTGBD, versus the additional-PTGBD group, including those who needed the additional-PTGBD after PTGBA. PATIENTS AND METHODS We conducted a post hoc analysis of our multi-institutional data. This study included 63 patients who underwent LC after PTGBA, and we compared the surgical outcomes between the only-PTGBA group (n = 56) and the additional-PTGBD group (n = 7). RESULTS No postoperative complications occurred among the 63 patients, and the postoperative hospital stay was 11 ± 12 days. Fourteen patients (22.2%) had a recurrence of cholecystitis, of whom 7 patients (11.1%) needed the additional-PTGBD after PTGBA. Significantly longer operative time (245 ± 74 vs 159 ± 65 min, P = 0.0017) and postoperative hospital stay (22 ± 27 vs 10 ± 9 d, P = 0.0118) and greater intraoperative blood loss (279 ± 385 vs 70 ± 208 mL, P = 0.0283) were observed among patients in the additional-PTGBD group compared with the only-PTGBA group, whereas the rates of postoperative complications (Clavien-Dindo grade ≥3: 0% each) and conversion to open surgery (28.6% vs 8.9%, P = 0.1705) were comparable. CONCLUSION PTGBA for acute cholecystitis could result in good surgical outcomes of subsequent LC, especially regarding postoperative complications. However, we should keep in mind that the additional-PTGBD after PTGBA failure, which sometimes happened, would be associated with increased operative difficulty and longer recovery.

Abstract
A 30s female complaining of anal pain and melena was referred to our hospital. The support by adolescent-and-young- adult(AYA)team was initiated after the first encounter. Colonoscopic examination revealed an ulcerated tumor on the anterior wall of anal canal with its anal margin on anal verge and the tumor was diagnosed as an adenocarcinoma. Contrast- enhanced CT and MRI revealed adjacency of tumor and vagina, enlarged lymph nodes and multiple pulmonary nodules. 18F-fluorodeoxyglucose(FDG)-positron emission tomography(PET)additionally revealed tracer accumulation in left sciatica, which led us to the diagnosis of advanced anal cancer. We planned and safely performed concomitant partial vaginal resection in robot-assisted laparoscopic abdominoperineal resection for the palliative purpose after discussion on physical and psychosocial issues including stoma and fertility with the patient, her family and AYA members. The pathological diagnosis was pT4b(vagina)N1aM1b, pStage ⅣB, and the local margin was pathologically negative. The postoperative course was smooth and she was discharged on postoperative day 16. Fifty one days after operation, she started systemic chemotherapy after decision on not to take ovarian samples and continues systemic chemotherapy as of writing. Support by AYA team was effective to facilitate the patient's decision-making and the communication between the patient and the medical team.
