Abstract
PURPOSE Choledochoduodenostomy (CDD) is performed to treat choledocholithiasis (CDL) cases where endoscopic stone removal is difficult. Recognizing CDD characteristics is important for CDL treatment planning. METHODS A total of 116 patients, including 33 patients ≥ 80 years old (29 with previous total gastrectomy, 19 with previous distal gastrectomy, 20 with built-up stones, 19 with periampullary diverticulum, 10 with confluence stones, 8 with repetitive recurrent stones, 4 with hard stones, 3 with endoscopic retrograde cholangiography [ERC] not available due to lack of cooperation, 2 with a history of pancreatitis post-ERC, and 2 in whom ERC could not be performed due to a disturbed anatomy) underwent CDD for CDL. Postoperative complications and long-term outcomes were evaluated. RESULTS The in-hospital mortality rate was 0%. The morbidity (grade ≥ IIIA according to the Clavien-Dindo classification) rates in the elderly (≥ 80 years old) and non-elderly (51-79 years old) patients were 3.0% (1/33) and 2.4% (2/83), respectively (p = 0.85). Long-term complications included cholangitis in eight (7%) patients, of which three cases were repetitive and seven had an operative history of total or distal gastrectomy. The incidence of postoperative cholangitis after total or distal gastrectomy was 15% (7/48), which was significantly higher than that involving other causes (1.5%, 1/68; p < 0.01). Two patients with cholangitis after total gastrectomy experienced early recurrence of lithiasis at 2 and 9 months after surgery. CONCLUSIONS CDD is safe, even in elderly patients. However, a history of total gastrectomy or distal gastrectomy may increase the incidence of postoperative cholangitis.

Abstract
AIM To study the effect of preoperative osteosarcopenia (OSP) on the prognosis of treatment (surgery or radiofrequency ablation (RFA)) in patients with Barcelona Cancer Liver Classification stage A hepatocellular carcinoma (BCLC A HCC). METHODS This study enrolled 102 patients with BCLC A HCC who underwent surgical resection (n = 45) and RFA (n = 57); the patients were divided into two groups: OSP (n = 33) and non-OSP (n = 69). Overall survival (OS) and disease-free survival (DFS) curves for both the groups and treatment methods (surgery and RFA) were generated using the Kaplan-Meier method and compared using the log-rank test. Univariate analyses for OS and DFS were performed using log-rank test. Multivariate analyses were performed for factors that were significant at univariate analysis by Cox proportional hazard model. RESULTS Multivariate analysis showed that OSP (HR 2.44; 95 % CI 1.30-4.55; p < 0.01) and treatment (HR 0.57; 95 % CI 0.31-0.99; p = 0.05) were significant independent predictors of DFS; and treatment (HR, 0.30; 95 % CI 0.10-0.85; p = 0.03) was a significant independent predictor of OS in the non-OSP group, in which the OS rate was significantly lower in patients treated with RFA than in those treated by resection (p = 0.01). CONCLUSIONS OSP is a prognostic factor for BCLC A HCC treatment. Surgical approach was associated with a significantly better prognosis in patients without OSP compared to those who underwent RFA.

Abstract
Objectives The aim of this study was to evaluate the effectiveness of transperineal repair of secondary perineal hernia (SPH) using a mesh with a memory-recoil ring. Methods Seven patients with SPH who underwent transperineal repair (TPR) between July 2010 and May 2022 were retrospectively analyzed. TPR was performed using a mesh with a memory-recoil ring. Results All SPHs developed after abdominoperineal resections in patients with anorectal malignancies. The median longitudinal and transverse diameters of the hernia orifice were 8 (7-10) cm and 6 (5-7) cm, respectively. In all cases, the mesh was fixed to the ischial tuberosity, residual levator muscle, coccygeus muscle, and coccyx after thorough dissection of the sac. The median operation time was 154 (142-280) min. Perioperative complications occurred in 2 cases (29%). One was enterotomy, which caused postoperative mesh infection requiring extraction of the mesh. The other was vaginal injury, which resulted in vaginal fistula but closed spontaneously. The median postoperative length of stay was 9 (5-14) days. No recurrence was observed during a median follow-up of 35 (9-151) months. Conclusions TPR using a mesh with a memory-recoil ring is safe, feasible and promising technique for SPH repairs.

Abstract
Background/Aim Surgical resection is recommended for nonfunctional pancreatic neuroendocrine neoplasms (NF-pNENs). However, metastasis is rare in patients with small lesions with histological grade 1 (G1); thus, observation is an optional treatment approach for small NF-pNENs. Texture analysis (TA) is an imaging analysis mode for quantification of heterogeneity by extracting quantitative parameters from images. We retrospectively evaluated the utility of TA in predicting histological grade of resected NF-pNENs in a multicenter retrospective study. Patients and Methods The utility of TA in preoperative prediction of grade were evaluated with 29 patients treated by pancreatectomy for NF-pNEN who underwent preoperative dynamic computed tomography scan between January 1, 2013 and December 31, 2020 at three hospitals affiliated with the Jikei University School of Medicine. TA was performed with dedicated software for medical imaging processing for determining histological tumor grade using dynamic computed tomography images. Results Histological tumor grades based on the 2017 World Health Organization Classification for Pancreatic Neuroendocrine Neoplasms were grade 1, 2 and 3 in 18, 10 and one patient, respectively. Preoperative grades by TA were 1 and 2/3 in 15 and 14 patients, respectively. The sensitivity, specificity and area under the curve for TA-oriented grade 1 lesions were 1.00, 0.889 and 0.965 (95% confidence interval=0.901-1.000), respectively. Conclusion TA is useful for predicting grade 2/3 NF-pNEN and can provide a safe option for observation for patients with small grade 1 lesions.

Abstract
We have developed a SERS stamp that can be pressed directly onto a solid surface for characterization of surface-adsorbed target molecules. The stamp was fabricated by transfer of a dense monolayer of SiO2 nanospheres from a glass surface onto a piece of adhesive tape and subsequent evaporation of silver. The performance of the resulting SERS stamps was evaluated by their exposure to methyl mercaptan vapor, and immersion in rhodamine 6G and ferbam solutions. It was found that beside the nanosphere diameter and metal deposition thickness, the extent of burial of the nanospheres into the adhesive tape, dictated by the pressure during the nanosphere transfer process, had a significant effect. We carried out FDTD calculations of the near field. Models are based on morphological information obtained from helium ion microscopy, which can provide high-resolution images of poor electrical conductors such as our SERS stamp. While one of our main eventual goals is detection of pesticides on agricultural produce, we have begun to take a careful step by testing our SERS stamp on better characterized surfaces such as a porous gel surface, having been immersed in fungicides such as ferbam. We also present our preliminary results with ferbam on oranges. It is expected that our well-characterized SERS stamp will play a role in shedding light on the poorly studied transfer process of target molecules onto a SERS surface as well as serving as a new SERS platform.

Abstract
BACKGROUND/AIM The docetaxel, 5-fluorouracil, and cisplatin (DCF) regimen is an effective form of chemotherapy for advanced esophageal cancer. However, the incidence of adverse events, such as febrile neutropenia (FN), is high. This study retrospectively examined whether pegfilgrastim treatment reduces FN development during DCF therapy. PATIENTS AND METHODS This study evaluated 52 patients who were diagnosed with esophageal cancer and underwent DCF therapy at Jikei Daisan Hospital, Tokyo, Japan, between 2016 and 2020. They were divided into non-pegfilgrastim and pegfilgrastim-treated groups, and side-effects of chemotherapy and cost-effectiveness of pegfilgrastim were examined. RESULTS Eighty-six cycles of DCF therapy were conducted (33 and 53 cycles, respectively). FN was observed in 20 (60.6%) and seven (13.2%) cases, respectively (p<0.001). The lowest absolute neutrophil count during chemotherapy was significantly lower in the non-pegfilgrastim group (p<0.001), and the number of days until improvement from nadir was significantly shorter in the pegfilgrastim group (9 vs. 11 days; p<0.001). No significant difference was found in the onset of grade 2 or more adverse events by Common Terminology Criteria for Adverse Events. However, renal dysfunction was significantly lower in the pegfilgrastim group (30.7% vs. 60.6%, p=0.038). Hospitalization costs were also significantly lower in this group (692,839 vs. 879,431 Japanese yen, p=0.028). CONCLUSION This study revealed the usefulness and cost-effectiveness of pegfilgrastim in prevention of FN in patients treated with DCF.

Abstract
BACKGROUND/AIM Sorafenib was previously the only targeted therapy for hepatocellular carcinoma (HCC). However, pharmaceutical therapy for HCC has undergone remarkable advances in recent years. Herein, we report cases of unresectable advanced HCC responding to pharmaceutical therapy resulting in improved prognosis through surgical intervention. PATIENTS AND METHODS Five patients with intermediate and advanced stage HCC treated with lenvatinib followed by hepatectomy between October 2019 and September 2022 were retrospectively reviewed. Patient characteristics, tumor factors, and treatment factors were compared. RESULTS The median patient age was 66 (60-79) years, and all patients (100%) were male. The median follow-up period was 10.4 months. All five patients received lenvatinib treatment for more than 2 months before surgery. Three patients achieved partial responses and 2 patients had stable disease with modified RESIST in response to lenvatinib. Three patients had a partial pathological response (50% or more tumor necrosis). Four patients underwent R0 resection and 3 cases had no recurrence. CONCLUSION Lenvatinib might be useful for intermediate and advanced HCC and long-term survival may be obtained by combining lenvatinib therapy with surgery.

Abstract
BACKGROUND Upper lumber hernia is a rare entity which can cause obstruction and strangulation. Laparoscopic technique has been considered effective for such hernia repairs; however, there is no report of use of the self-expanding mesh. CASE PRESENTATION A 77-year-old woman visited to our hospital complaining of a bulge of about 5 cm in the left lumbar dorsal region while standing. Abdominal CT and MRI scans showed a fascial defect in the left lumbar abdominal wall and confirmed the presence of a hernia, in which retroperitoneal fatty tissue and the descending colon protruded. Transabdominal preperitoneal repair (TAPP) was performed and the operative findings revealed the hernia orifice, 3 × 2.5 cm in diameter, between two intercostal nerves. To avoid nerve injury or entrapment, the number of mesh fixation was desirable minimum; therefore, a self-expanding mesh with a memory-recoil ring was used. The mesh, 9.5 × 13 cm in diameter, was placed and tacked to the abdominal wall at two points, 1 cm ventral and dorsal to the hernia orifice. The postoperative course was uneventful and no pain or recurrence was observed with follow-up of 6 months.

Abstract
BACKGROUND/AIM Evidence on the optimal extent of lymph node dissection for left-sided pancreatic ductal adenocarcinoma (PDAC) is scarce. The aim of the current study was to compare the long-term outcomes of patients who underwent D1 distal pancreatectomy (DP) with D2 DP for left-sided PDAC. PATIENTS AND METHODS Patients undergoing DP for left-sided PDAC at the four institutions affiliated to The Jikei University were enrolled in this study. Patients were divided into D1 and D2 groups. Patients' clinical characteristics, overall survival (OS), and relapse-free survival (RFS) were compared between the two groups before and after propensity-score matched (PSM) analysis. RESULTS Of 145 patients with left-sided PDAC, 55 patients underwent D1 DP and 90 underwent D2 DP, of whom 38 matched pairs were included in the PSM analytic cohort. In the unmatched cohort, no significant difference was found between the D1 and D2 groups for both OS (median 2.51 vs. 3.07 years; p=0.709) and RFS (median 1.47 vs. 1.27 years; p=0.565). After PSM, OS (median 2.37 vs. 3.56 years; p=0.407) and RFS (median 1.35 vs. 1.11 years; p=0.542) were not significantly different between the two groups. In a comparison of regional and systemic recurrence sites, no significant difference was observed between the two groups (p=0.500). CONCLUSION The long-term survival of D1 DP for left-sided PDAC was not inferior to D2 DP. In an era in which the importance of multidisciplinary treatment for PDAC has been documented, unnecessary extended surgery should be avoided.

Abstract
Abstract
Background
Surgery for perforated rectal cancer is technically difficult because of paralytic dilatation due to generalized fecal peritonitis, the presence of a bulky tumor, and fecal retention due to obstruction. Transanal total mesorectal excision (TaTME) is the latest minimally invasive transanal technique pioneered to facilitate difficult pelvic dissections. It can provide a good surgical field linearly from the perineal side and reduce manipulations from the intraabdominal side. Here, we present two cases of emergency TaTME performed for perforated rectal cancer.
Case presentation
The patients were a 38-year-old female and a 75-year-old male. They were diagnosed with perforated rectal cancer and were in a state of septic shock. Emergency Hartmann’s procedure was performed in both cases. Intraoperative findings showed fecal contamination of the entire abdomen and dilated intestines and bulky tumors with perforation. The female patient had multiple uterine fibroids, and the male patient had an enlarged prostate. For both patients, dissection of the mesorectum to the anal side of the tumor and transection of the rectum on the anal side of the tumor via a linear stapler were considered difficult because of the insufficient surgical field of view into the pelvis. Therefore, a two-team approach with TaTME was adopted. En bloc resection of the rectum was completed by collaboration of the abdominal team and the transanal team, and the autonomic nerves were successfully preserved. Finally, the specimens were resected, and the anal edge of the rectum was closed with a purse-string suture by the transanal team. Although these two cases were emergency surgeries in difficult situations, the cancer lesions were successfully and safely removed without involvement of the resection margin.
Conclusions
This is the first report of emergency TaTME. Although these cases were emergency operations in a situation where it was difficult to pursue radical resection—and often times in these situations, the operation may end with only stoma creation—the specimens were safely resected. Emergency TaTME is a useful procedure for treatment of perforated rectal cancer.

Abstract
BACKGROUND Adjuvant chemotherapy is recommended for patients with pancreatic cancer after curative resection. However, there is limited evidence regarding the efficacy and prognostic factors for adjuvant chemotherapy in patients with stage I pancreatic cancer. This study aimed to identify patients in whom chemotherapy was effective and to detect prognostic factors for stage I pancreatic cancer based on guidelines of the 8th edition of the Union for International Cancer Control (UICC). METHODS Between 2009 and 2017, 108 patients diagnosed with stage I pancreatic cancer were enrolled in this study. They were distributed into invasion (n = 68) and non-invasion (n = 40) groups. The relationship between clinicopathological variables, including various prognostic factors, disease-free survival (DFS), and overall survival (OS), were investigated by univariate and multivariate analyses. RESULTS Five-year survival in all patients with stage I pancreatic cancer was 38.9%. Adjuvant chemotherapy failed to improve DFS or OS in patients with stage I cancer (DFS, p = 0.26; OS, p = 0.30). In subgroup analysis, adjuvant chemotherapy significantly improved DFS (multivariate-adjusted hazard ratio (HR), 0.40; 95% confidence interval [CI], 0.21-0.78; p = 0.007) and OS (multivariate-adjusted HR, 0.32; 95% CI, 0.15-0.68; p = 0.003) in the invasion group than in non-invasion group. In contrast, in the non-invasion group, adjuvant chemotherapy failed to improve DFS and OS in univariate analysis (DFS, p = 0.992; OS, p = 0.808). CONCLUSION For stage I pancreatic cancer, based on guidelines of the UICC 8th edition, adjuvant chemotherapy may benefit patients with extrapancreatic invasion.

Abstract
BACKGROUND Necrotizing fasciitis after pancreaticoduodenectomy (PD) has never been reported. We experienced a case of necrotizing fasciitis caused by pseudoaneurysmal hemorrhage after PD. CASE PRESENTATION A 72-year-old male was diagnosed with cholangiocarcinoma and underwent PD. Bile leakage was detected postoperatively, conservatively resolved, and the patient was discharged on the 36th day after surgery. On the 42nd day after surgery, a pseudoaneurysm of the gastroduodenal artery ruptured. Transcatheter arterial embolization was performed for hemostasis: however, a large intra-abdominal abscess caused by an infected hematoma was recognized. On the 57th day after surgery, the patient developed necrotizing fasciitis. He underwent debridement with skin reconstruction using a latissimus dorsi flap and skin transplantation. Costochondritis and liver metastasis were detected on the 267th day after surgery. Infection was controlled by rib cartilage resection, debridement, and negative pressure wound therapy. Chemotherapy involving gemcitabine and cisplatin was initiated on the 460th day after the initial surgery with a partial response (PR) and was continued for more than one year. CONCLUSIONS We herein reported a rare case of necrotizing fasciitis following hematoma infection after PD that was treated using multidisciplinary therapy with PR following chemotherapy.

Abstract
BACKGROUND In parastomal hernia (PH) repair, laparoscopic Sugarbaker technique (LS) is considered the best practice; however, meshes specific for LS repairs ceased to be available. PURPOSE The aim of the study was to evaluate feasibility of using a physician-modified mesh (tailored mesh: TM) in LS. METHODS Thirty-three patients who underwent LS for PH between June 2012 and September 2021 were examined to compare surgical outcomes between LS with TM (n = 11) and with a ready-made specific mesh (SM, n = 22). All meshes were coated plastic meshes. Statistical analysis was performed with the Mann-Whitney U test and Fisher's exact test. P < .05 was considered to be statistically significant. RESULTS We compared the outcomes of TM with SM in LS for similar hernia types during median follow-up periods of 23 (range, 2-29) and 74 (range, 36-110) months (P < .0001), respectively. The median operation times were 146 (range, 45-423) for TM and 193 (range, 65-386) minutes for SM (P = .2301). Perioperative complications were observed in one TM patient (9%) and two SM patients (9%) (P = 1.0000). The lengths of postoperative stay were similar. Recurrence was observed in two cases in the SM group (9%) within 1 year after the operation. CONCLUSION In LS, TM seems to be a feasible mesh comparable to SM within short- and mid-term follow-up.

Abstract
Introduction The albumin-bilirubin (ALBI) grade is a novel indicator of the liver function. Some studies showed that the ALBI grade was a prognostic and predictive biomarker for the efficacy of chemotherapy in cancer patients. The association between the ALBI grade and outcomes in patients with non-small-cell lung cancer (NSCLC) treated with cancer immunotherapy, however, is poorly understood. Methods We retrospectively enrolled 452 patients with advanced or recurrent NSCLC who received anti-programmed cell death protein 1 (PD-1)-based therapy between 2016 and 2019 at three medical centers in Japan. The ALBI score was calculated from albumin and bilirubin measured at the time of treatment initiation and was stratified into three categories, ALBI grade 1-3, with reference to previous reports. We examined the clinical impact of the ALBI grade on the outcomes of NSCLC patients receiving anti-PD-1-based therapy using Kaplan–Meier survival curve analysis with log-rank test and Cox proportional hazards regression analysis. Results The classifications of the 452 patients were as follows: grade 1, n = 158 (35.0%); grade 2, n = 271 (60.0%); and grade 3, n = 23 (5.0%). Kaplan–Meier survival curve analysis showed that the ALBI grade was significantly associated with progression-free survival and overall survival. Moreover, Cox regression analysis revealed that the ALBI grade was an independent prognostic factor for progression-free survival and overall survival. Conclusion The ALBI grade was an independent prognostic factor for survival in patients with advanced or recurrent NSCLC who receive anti-PD-1-based therapy. These findings should be validated in a prospective study with a larger sample size. ALBI grade is calculated from albumin and bilirubin. We evaluated the impact of ALBI grade on survival in NSCLC patients receiving immune checkpoint inhibitors. ALBI grade was an independent prognostic factor for progression-free survival (PFS) and overall survival (OS). ALBI grade effectively stratified PFS and OS in patients with performance status 1-3. ALBI grade was significantly associated with PFS and OS, regardless of programmed death ligand-1.

Abstract
BACKGROUND The outlet obstruction (OO) rate is 5.4-18.4% after defunctioning ileostomy (DI) following rectal cancer resection to reduce the incidence and severity of anastomotic leakage; OO affects a patient's quality of life and prolongs hospitalization. PATIENTS AND METHODS A retrospective analysis was performed of patients who underwent anterior rectal resection and DI for rectal cancer. RESULTS Among 100 patients undergoing anterior rectal resection with DI for rectal cancer, 28 (28%) developed OO. Anastomotic leakage and a rectus abdominis muscle thickness ≥10 mm on preoperative computed tomography were significantly associated with the risk of OO in univariate analysis. Multivariate analysis also demonstrated that anastomotic leakage (odds ratio=4.320, 95% confidence interval=1.280-14.60, p=0.019) and rectus abdominis muscle thickness ≥10 mm (odds ratio=3.710, 95% confidence intervaI=1.280-10.70, p=0.016) were significantly risk factors for OO. CONCLUSION When OO is observed, an anastomotic leakage should be suspected, especially if there is a high rectus abdominis muscle thickness.

Abstract
Background The surgical difficulty of laparoscopic cholecystectomy (LC) after percutaneous transhepatic gallbladder drainage (PTGBD) remains unknown. This study aimed to establish a scoring system (SS) to predict the necessity of a bailout procedure during LC after PTGBD and to evaluate the relationship between SS and perioperative complications. Methods We retrospectively studied 70 patients who underwent LC after PTGBD. Preoperative factors potentially predictive of the need for the bailout procedure were analyzed. The SS included significantly predictive factors, with their cutoff values determined by receiver operating characteristic curves. Patients were assigned a score of 1 when exhibiting only one of these abnormalities. We compared the perioperative factors between three groups with scores of 0, 1, or 2. The SS was applied to another series of 65 patients for validation. We compared the score‐2 patient perioperative factors between LC with the bailout procedure and open cholecystectomy from the beginning (OC). Results Independent predictors were time until PTGBD after symptom onset and the maximal wall gallbladder thickness (cutoff values: 3 days and 10 mm, respectively). The high‐score group was significantly associated with bile duct injury (BDI). The sensitivity and specificity of our SS were 75.0% and 98.1% in validation, respectively. The score‐2 OC and laparoscopic subtotal cholecystectomy (LSC) groups had no BDI. Conclusions The SS using time until PTGBD after symptom onset and gallbladder wall thickness for predicting the need for the bailout procedure correctly predicted the need. The scores might be associated with the risk of BDI, and LSC or OC might be a better choice for score‐2 patients.

Abstract
BACKGROUND Previously, we developed an image-guided navigation system (IG-NS) incorporating augmented reality technology. Nevertheless, the system could still only aid the operator by presenting imagery and was short of achieving the goal of developing a real navigation system. Therefore, we developed a recognised position-guided navigation system (RP-NS) and herein reported the functionality and usefulness of this system in a phantom model for clinical applications. METHODS We developed RP-NS which was reconstructed by adding the positional recognition and instruction functions with the cautions by displaying the images on the monitor with a voice to the IG-NS. We evaluated accuracy of positional recognition and instruction functions using phantom model. By utilising the chronological recording of the tip position of the surgical apparatus, the surgical precision of the operators was assessed. Finally, the feasibility of improvements in surgical precision using this system was evaluated. RESULTS The RP-NS indicated an accuracy of the position recognition functions with an error of 2.7 mm. The surgeons could perform partial hepatectomies within mean value of 7.5% error as compared with calculated volume according to the instruction. Improvements in surgical precision using this system were obtained on the surgeons with different levels. CONCLUSIONS The RP-NS was highly effective as a navigation system owing to precise positional recognition and adequate instruction functions. Therefore, these results indicate that the use of this system may complement differences in proficiency, and numerically evaluate surgical skills and analyse tendencies of surgeons.

Abstract
Lymphangiomas are classified as lymphatic malformations, which are more common in children and rare in adults. It frequently occurs in the cervical and axillary regions and uncommonly in the retroperitoneum. A 39-year-old woman presented to our department for the investigation for a 55 mm asymptomatic mass in the right anterior adrenal cavity. Abdominal ultrasound showed a tumor containing cysts in the right anterior adrenal cavity. Contrast-enhanced computed tomography showed that the tumor was poorly contrasted and ill-defined. Magnetic resonance imaging suggested that the tumor contained a small amount of fat. The tumor tended to grow, and the possibility of malignant diseases such as liposarcoma could not be excluded. Therefore, surgical resection was performed. Since intraoperative findings showed that the tumor tightly invaded to the duodenum and pancreatic head, a pancreaticoduodenectomy was selected. The entire tumor was removed without exposing the tumor. Macroscopic findings indicated that the specimen was 55 mm in size, indistinctly demarcated, yellow-white in color, and polycystic. Histologically, lymphovascular proliferation was observed with infiltration of the pancreatic head and the duodenal muscle layer. The diagnosis of lymphangioma was finally made. There was no recurrence 2 years after surgery.

Abstract
INTRODUCTION Osteopenia, which is defined as a decrease in bone mineral density, has been recently recognized as a metabolic and an oncological biomarker for surgery in patients with malignancy. We aimed to study the prognostic impact of osteopenia in patients with pancreatic cancer (PC) after resection. METHODS A total of 56 patients who underwent curative resection of PC were retrospectively investigated. The skeletal muscle index at the third lumbar spine and bone mineral density at the 11th thoracic vertebra were measured using computed tomography. RESULTS Sarcopenia and osteopenia were identified in 24 (43%) and 27 (48%) patients, respectively. The overall and disease-free survival rates were significantly lower in the sarcopenia group than in the non-sarcopenia group (p < 0.01 and p < 0.01, respectively) and in the osteopenia group than in the non-osteopenia group (p < 0.01 and p < 0.01, respectively). In multivariate analysis, sarcopenia (odds ratio [OR] 4.05; 95% confidence interval [CI] 1.23-13.38; p = 0.02) was a significant independent predictor of 1-year disease-free survival. Further, sarcopenia (OR 6.00; 95% CI 1.46-24.6; p = 0.01) and osteopenia (OR 4.66; 95% CI 1.15-18.82; p = 0.03) were significant independent predictors of 2-year overall survival. CONCLUSION Osteopenia is a significant negative factor for 2-year overall survival after curative resection of PC.

Bioactive glasses (BAG) are used as bone-graft substitutes in orthopaedic surgery. A specific BAG scaffold was developed by sintering BAG-S53P4 granules. It is hypothesised that this scaffold can be used as a bone substitute to fill bone defects and induce a bioactive membrane (IM) around the defect site. Beyond providing the scaffold increased mechanical strength, that the initial inflammatory reaction and subsequent IM formation can be enhanced by coating the scaffolds with poly(DL-lactide-co-glycolide) (PLGA) is also hypothesised. To study the immunomodulatory effects, BAG-S53P4 (± PLGA) scaffolds were placed on monolayers of primary human macrophage cultures and the production of various pro- and anti-inflammatory cytokines was assessed using reverse transcriptase quantitative polymerase chain reaction (RT-qPCR) and ELISA. To study the osteogenic effects, BAG-S53P4 (± PLGA) scaffolds were cultured with rabbit mesenchymal stem cells and osteogenic differentiation was evaluated by RT-qPCR and matrix mineralisation assays. The scaffold ion release was quantified and the BAG surface reactivity visualised. Furthermore, the pH of culture media was measured. BAG-S53P4 scaffolds had both anti-inflammatory and osteogenic properties that were likely attributable to alkalinisation of the media and ion release from the scaffold. pH change, ion release, and immunomodulatory properties of the scaffold could be modulated by the PLGA coating. Contrary to the hypothesis, the coating functioned by attenuating the BAG surface reactions and subsequent anti-inflammatory properties, rather than inducing an elevated inflammatory response compared to BAG-S53P4 alone. These results further validated the use of BAG-S53P4 (± PLGA) scaffolds as bone substitutes and indicate that scaffold properties can be tailored to a specific clinical need.
