Abstract
INTRODUCTION Enhanced recovery after surgery (ERAS) colorectal programs have been shown to improve the length of stay (LOS) without increasing hospital resource utilization at academic centers worldwide. A multidisciplinary ERAS protocol that includes preoperative, intraoperative, and postoperative management guidelines was recently implemented at our urban, racially diverse, and academically affiliated community hospital. A delivery option was provided to reduce barriers to care. Given our unique patient population, the objective of our study was to determine if improvements in outcomes were reproducible in our hospital. METHODS This is a retrospective study of patients undergoing elective colectomy at New York-Presbyterian Queens Hospital between January 1, 2015, and December 31, 2020. Patient outcomes were compared between surgeries performed under standard practice (all colectomies prior to April 2017) and those performed after the implementation of the ERAS protocol. Demographic and perioperative data were abstracted from a prospectively derived database used to submit data to the National Surgical Quality Improvement Program. Additional data were obtained from chart review. RESULTS Six hundred five elective colectomies were performed by 12 surgeons (range 1-228 cases) during the study period. Of these, 22 were performed open (41% followed ERAS), 467 were performed laparoscopically (57% followed ERAS), and 116 were performed robotically (74% followed ERAS). The average patient age was 64 y. Of which, 55% were male; 34% were Asian, 27% were non-Hispanic Caucasian, 27% were Hispanic, and 11% were Black or African American (all P-values > 0.05 for ERAS versus non-ERAS). Average duration of procedure was longer in the ERAS group (262 min versus 243 min, P = 0.04), although when stratified by procedure type, this relationship held true only for laparoscopic procedures. Hospital LOS was significantly shorter in the ERAS group (4.3 versus 5.4 d, P < 0.001) and this relationship held true for procedures performed both laparoscopically (4.2 versus 5.3 d, P = 0.01) and robotically (4.1 versus 5.1 d, P = 0.04). Of the ERAS group, patients who opted for delivery of ERAS components (n = 205) had the shortest LOS when compared to patients who picked up components (n = 91) or opted out of ERAS (n = 309) (4.1 versus 4.4 versus 5.2 d, P = 0.003). No significant differences were found for 30-d mortality, 30-d readmission, wound infection, or other postoperative complications (all P-values > 0.05). CONCLUSIONS Implementation of an ERAS protocol in an urban, diverse, academically affiliated community hospital is associated with reductions in LOS for colectomies performed both laparoscopically and robotically. Facilitating ERAS compliance with a delivery option was also associated with improvements in hospital LOS. Preoperative nutrition supplementation was not associated with outcomes. No differences in mortality, readmission rates, or rates of postoperative complications were found.

Abstract
Measuring CA 19-9 antigen level is critical for early diagnosis of pancreatic cancer, monitoring the treatment process, and predicting disease recurrence. The purpose of this research is to assess the application of novel few-layered TiS3 nanoribbons material as a channel material in electrolyte-gated field-effect transistor immunosensor for rapid detection of CA 19-9 antigen as a cancer marker. Accordingly, TiS3 nanoribbons were produced through liquid-phase exfoliation of as-synthesized TiS3 whiskers in N, N-dimethylformamide. Then, dispersed TiS3 nanoribbons were drop cast onto the FET surface to form an active channel material between source and drain electrodes. Subsequently, the channel surface was modified by utilizing 1-naphthylamine (NA) and glutaraldehyde (GA) to strengthen the binding of monoclonal antibody 19-9 to TiS3 nanoribbons. Spectroscopic and microscopic methods were utilized for comprehensive characterizations. Electrical characterization of electrolyte-gated TiS3 nanoribbons field-effect transistor represented a depletion-mode n-type behavior with field-effect mobility of 0.059 cm2/Vs, current on/off ratio of 10.88 and subthreshold swing (SS) of 450.9 mV/decade. With increasing in CA 19-9 antigen concentration from 1.0 × 10-12 U/mL to 1.0 × 10-5 U/mL, a decrease in the drain current occurred with high sensitivity of 0.04 μA/decade and a detection limit of 1.3 × 10-13 U/mL. Additionally, the proposed TiS3 nanoribbons FET immunosensor exhibited outstanding selectivity, and its good performance was compared with an enzyme-linked immunosorbent assay (ELISA) for spiked real human serum samples. The good and satisfactory obtained results of the proposed immunosensor suggest that the developed platform can be a superb candidate for cancer diagnosis and therapeutic monitoring.

Abstract
Hydatid disease is a worldwide public health problem, especially in endemic countries, caused by the larval stage of Echinococcus granulosis. The pancreatic location of this disease is exceptional, representing only 1% of all possible locations, making this a widely misdiagnosed entity. We report a case of a 42-year-old man with a history of alcoholism and recurring abdominal pain, who presented to the emergency department with acute pancreatitis revealing a hydatid pancreatic cyst mimicking as a pseudocyst of the pancreas. The diagnosis was established using computed tomography and magnetic resonance imaging.

Abstract
The aim of the study is to provide a comprehensive assessment of incidence and survival trends of epithelial ovarian cancer (EOC) by histological subtype across seven high income countries (Australia, Canada, Denmark, Ireland, New Zealand, Norway and the United Kingdom). Data on invasive EOC diagnosed in women aged 15 to 99 years during 1995 to 2014 were obtained from 20 cancer registries. Age standardized incidence rates and average annual percentage change were calculated by subtype for all ages and age groups (15-64 and 65-99 years). Net survival (NS) was estimated by subtype, age group and 5-year period using Pohar-Perme estimator. Our findings showed marked increase in serous carcinoma incidence was observed between 1995 and 2014 among women aged 65 to 99 years with average annual increase ranging between 2.2% and 5.8%. We documented a marked decrease in the incidence of adenocarcinoma "not otherwise specified" with estimates ranging between 4.4% and 7.4% in women aged 15 to 64 years and between 2.0% and 3.7% among the older age group. Improved survival, combining all EOC subtypes, was observed for all ages combined over the 20-year study period in all countries with 5-year NS absolute percent change ranging between 5.0 in Canada and 12.6 in Denmark. Several factors such as changes in guidelines and advancement in diagnostic tools may potentially influence the observed shift in histological subtypes and temporal trends. Progress in clinical management and treatment over the past decades potentially plays a role in the observed improvements in EOC survival.

Abstract
The use of enteral nutrition (EN) continues to increase given benefits. However, with this increase in use, it is also becoming evident that enteral feeding intolerance (EFI) is also quite prevalent, leading to the inability to meet nutrition needs in many patients. Given the wide variability in the EN population as well as the number of formulas available, there is not a clear consensus regarding the best approach to EFI management. One approach that is emerging to improve EN tolerance is the use of peptide-based formulas (PBFs). PBFs refer to enteral formulas containing proteins that have been enzymatically hydrolyzed to dipeptides and tripeptides. These hydrolyzed proteins are often combined with higher medium-chain triglyceride content to generate an enteral formula that is essentially easier to absorb and utilize. Emerging data demonstrate that the use of PBF in patients with EFI may improve clinical outcomes along with a corresponding reduction in healthcare utilization and potentially the cost of care. This review aims to navigate through key clinical applications and benefits of PBF and to discuss relevant data shared in the literature.

Abstract
BACKGROUND The aim of this study was to assess the effect of preoperative biologic therapy on the surgical outcome of Crohn's disease (CD) patients undergoing repeat ileocolic resection. METHODS This was a retrospective analysis of all CD patients who underwent repeat ileocolic resection at Cleveland Clinic Florida between January 2011 and April 2021. Patients were divided into two groups: treatment biologic therapy prior to surgery and controls. RESULTS Sixty-five patients (31males, median age 54 [range 23-82] years) were included in the study. Twenty nine (44.6%) were treated with biologic therapy prior to repeat ileocolic resection. No demographic differences were found between the biologic therapy and control groups. In addition, no differences were found in mean time from index ileocolic resection (p = 0.9), indication for surgery (p = 0.11), and preoperative albumin (p = 0.69). The majority of patients (57; 87.7%) were operated on laparoscopically, and mean overall operation time was 225 (SD 49.27) min. Overall, the postoperative complication rate was 43.1% (28 patients) and median length of stay was 5 (range 2-21) days. Postoperative complications were more common in the control group, compared to the biologic therapy group (55.6 vs 27.5%; p = 0.04). Conversion rate (35.7 vs 20.7%; p = 0.24), operation time (223 vs 219 min; p = 0.75), length of stay (5.2 vs 5.9 days; p = 0.4), and readmission (16.6 vs 11.1%; p = 0.72) were similar between the two groups. Multivariate analysis of risk factors for postoperative complications showed that biologic treatment was correlated with a lower risk (HR -0.28, CI 95% -0.5596 to -0.01898, p = 0.03). CONCLUSIONS Patients treated with biologic therapy for CD who underwent repeat ileocolic resection had fewer postoperative complications.

Abstract
BACKGROUND The aim of this review was to explore the role of three-dimensional (3D) printing in colorectal surgical education and procedural simulation, and to assess the effectiveness of 3D-printed models in anatomic and operative education in colorectal surgery. METHODS A systematic review of the literature was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify relevant publications relating to the use of 3D-printed models in colorectal surgery in an educational context. The search encompassed OVID Medline, Web of Science and EMBASE including papers in English published from 1 January 1995 to 1 January 2023. A total of 1018 publications were screened, and 5 met the criteria for inclusion in this review. RESULTS Four distinct 3D models were described across five studies. Two models demonstrated objective benefits in the use of 3D-printed models in anatomical education in academic outcomes at all levels of learner medical experience and were well accepted by learners. One model utilised for preoperative visualisation demonstrated improved operative outcomes in complete mesocolic excision compared with preoperative imaging review, with a 22.1% reduction in operative time (p < 0.001), 9.2% reduction in surgical duration (p = 0.035) and 37.3% reduction in intraoperative bleeding volume amongst novice surgeons (p < 0.01). Technical simulation has been demonstrated in a feasibility context in one model but remains limited in scope and application on account of the characteristics of available printing materials. CONCLUSIONS 3D printing is well accepted and effective for anatomic education and preoperative procedural planning amongst colorectal surgeons, trainees and medical students but remains a technology in the early stages of its possible application. Technological advancements are required to improve the tissue realism of 3D-printed organ models to achieve greater fidelity and provide realistic colorectal surgical simulations.

Abstract
OBJECTIVES Alveolar echinococcosis (AE) recurrence is one of the major stakes in patients undergoing surgery, the main curative treatment. Preliminary data demonstrated an effect of programmed death-ligand1 (PD-L1) inhibitors on AE proliferation in animals. The current study aimed to analyze the prognostic value of PD-L1 expression in tissue samples of patients with AE undergoing surgery. METHODS A cross-sectional study of patients operated for AE between 2002 and 2017 was performed. Patients with recurrence were matched 1: 2 with patients without recurrence. The matching criteria were PNM staging (P = hepatic localization of the parasite, N = extra-hepatic involvement of neighboring organs, and M = absence or presence of metastasis), resection status, preoperative albendazole treatment, and lesion size. PD-L1 immunohistochemistry staining was performed in surgical liver specimens. The expression of PD-L1 was assessed in immune cells. Disease-free survival was calculated using the Kaplan-Meier method. RESULTS Among 68 consecutive patients, eight patients with recurrence were matched to 16 patients without recurrence. PD-L1 was overexpressed in patients with recurrence (recurrence: PD-L1 <1%: one, PD-L1 ≥1%: seven; no recurrence: PD-L1 <1%: nine, PD-L1 ≥1%: seven, P = 0.040). Moreover, patients with lower PD-L1 expression (<1%) showed better median disease-free survival (120 months, 95% confidence interval 104-135 vs 74, 95% confidence interval 44-104, P = 0.050). CONCLUSION These findings highlight the proof of concept of PD-L1 in AE, but further data on its prognostic importance and the role of immune checkpoint blockade as a promising therapeutical strategy are needed.

Abstract
BACKGROUND The interplay of carbohydrate antigen 19-9 (CA19-9) and tumor burden score (TBS) within intrahepatic cholangiocarcinoma remains ill-defined. We evaluated the roles of TBS and CA19-9 relative to overall survival (OS) and recurrence, as well as the predictive ability of the combined TBS and CA19-9 (CTC) grading system. STUDY DESIGN Patients undergoing liver resection for intrahepatic cholangiocarcinoma between 2000 and 2020 were identified using a multi-institutional database. The impact of CA19-9 and TBS on 5-year OS and 3-year recurrence was assessed, along with the prognostic accuracy of the CTC grading system (ie the composite score of CA19-9 level and TBS). RESULTS Among 831 patients, the median age was 58.2 years and 482 (58.0%) were male. The median [IQR] CA19-9 level was 49.7 [17.0, 221.0] U/mL and TBS was 6.1 [4.1, 8.3]. Median [IQR] and 5-year OS were 36.9 [32.3, 43.1] months and 38.9%, respectively; 3-year recurrence was 68.9%. Five-year survival varied relative to CA19-9 (low vs high, 49.0% vs 19.7%) and TBS (low vs high, 53.6% vs 26.9%) (p < 0.001 for both). On multivariable analysis, high CA19-9 (hazard ratio [HR] 2.02, 95% CI 1.64 to 2.49) and high TBS (HR 1.64, 95% CI 1.32 to 2.06) remained independently associated with OS. In turn, the CTC grading score stratified 5-year OS (low vs intermediate vs high CTC, 57.7% vs 39.9% vs 12.6%; p < 0.001) and remained an independent prognostic factor (referent, low CTC; [intermediate CTC] HR 1.54, 95% CI 1.18 to 2.01; [high CTC] HR 3.28, 95% CI 2.47 to 4.36). CONCLUSIONS The interplay between tumor morphology and biology dictates long-term prognosis after liver resection for intrahepatic cholangiocarcinoma. Prognostic models such as the CTC grading system may inform discussions around prognosis, as well as help identify which patients with ICC may benefit more from neoadjuvant chemotherapy rather than up-front surgery.

Abstract
OBJECTIVE Human papillomavirus (HPV)-related squamous intraepithelial lesion (SIL) or malignancy is associated with a significantly increased risk of second-site SIL or malignancy. The primary objective of this study was to determine the feasibility and acceptability of concurrent anal, cervical, and vulvovaginal screening in patients with a history of HPV-related gynecologic high-grade SIL or malignancy. The secondary objective was to assess subjects' knowledge regarding HPV screening and risks. METHODS Women with high-grade cervical, vulvar, or vaginal SIL or malignancy were enrolled during a 1-year pilot period. Subjects with cervical SIL or malignancy underwent vulvar examination and anoscopy. Subjects with vulvovaginal SIL or malignancy underwent Pap test if indicated and anoscopy. Appropriate referrals were made for abnormal findings. Feasibility was assessed by compliance using study acceptance rate, screening procedure adherence, and referral adherence. Acceptability was assessed using a Likert-scaled question after completion of screening procedures. RESULTS One hundred three women with a diagnosis of high-grade vulvovaginal or cervical SIL or carcinoma were approached regarding study enrollment; of these, 74 (71.8%) enrolled. The median score on the HPV knowledge assessment was 8.1 ± 1.6 (max score 10). Seventy-three (98.6%) of 74 patients rated the screening procedures as acceptable (score of 5/5). On examination, 14 (18.9%) subjects had abnormalities noted; 7 (9.5%) were referred for colorectal surgical evaluation, and 6/7 (85.7%) were compliant with their referral appointments. CONCLUSIONS Screening examinations for other HPV-related SILs and malignancies, including Pap tests, vulvovaginal inspection, and anoscopy, are acceptable to patients, with abnormal findings in almost 1 in 5 women.

Abstract
In recent years, laparoscopic techniques for liver resection or living donor hepatectomy have become common surgical methods. However, reports on laparoscopic surgeries for recipients are lacking. Our center has launched the minimally invasive living donor liver transplantation (LDLT) program in March 2020, which is led by two surgeons who are experienced in laparoscopic surgeries. Recently, we reported our first successful pure laparoscopic recipient explant hepatectomy and the first laparoscopic explant hepatectomy and robotic-assisted graft implantation. In this article, we introduce a series of minimally invasive surgical cases that were conducted by a single experienced surgeon to share our early experiences leading to our recent successes. We included 10 cases performed from June 2020 to May 2021 in our initial attempt at laparoscopic explant hepatectomy, graft implantation using midline incision, and robotic-assisted graft implantation surgery. The first four cases required open conversion during the liver mobilization process because of bleeding. The next two cases required open conversion to facilitate portal vein and hepatic artery division. We successfully performed pure laparoscopic explant hepatectomy in the last four cases. For the last case, we attempted to perform graft implantation using a robotic system, but bleeding required open conversion. All patients recovered without any significant acute postoperative problems and were discharged within 2 weeks. All 10 patients were followed up at outpatient clinics, and only one of the 10 patients had a late complication of LDLT. This study has shown that the minimally invasive approach in LDLT may be conducted safely without significant complications if it is performed by highly experienced surgeons working in high-volume centers.

Abstract
BACKGROUND Nonoperative management of acute appendicitis is a safe and effective alternative to appendectomy, though rates of treatment failure and disease recurrence are significant. The purpose of this study was to determine whether COVID-19-positive children with acute appendicitis were more likely to undergo nonoperative management when compared to COVID-19-negative peers and to compare clinical outcomes and healthcare use for these groups. METHODS A retrospective cohort study of children <18 years with acute appendicitis across 45 US Children's Hospitals during the first 12 months of the COVID-19 pandemic was performed. Operative management was defined as appendectomy or percutaneous drain placement, whereas nonoperative management was defined as admission with antibiotics alone. Multivariable hierarchical logistic regression using an exact matched cohort was used to determine the association between COVID-19 positivity and nonoperative management. The secondary outcomes included intensive care unit admission, mechanical ventilation, length of stay, nonoperative management failure rates, and hospital variation in nonoperative management. RESULTS Of 17,481 children in the cohort, 581 (3.3%) were positive for COVID-19. The odds of nonoperative management was significantly higher in the COVID-19-positive group (adjusted odds ratio [95% confidence interval]: 13.4 [10.7-16.8], P < .001). Patients positive for COVID-19 had increased odds of intensive care unit admission (adjusted odds ratio [95% confidence interval]: 3.78 [2.01-7.12], P < .001) and longer length of stay (median 2 days vs 1 day, P < .001). Hospital rates of nonoperative management ranged from 0% to 100% for COVID-19-positive patients and 0% to 42% for COVID-19-negative patients. CONCLUSION Children with concurrent acute appendicitis and COVID-19 positivity are significantly more likely to undergo nonoperative management. Both groups experience infrequent nonoperative management failure rates and rare intensive care unit admissions. Marked hospital variability in nonoperative management practices was demonstrated.

Abstract
BACKGROUND Anatomical variations in the liver arterial supply are quite common and can affect the surgical strategy when performing a minimally invasive pancreaticoduodenectomy (MIPD). Their presence must be preemptively detected to avoid postoperative liver and biliary complications. DATA SOURCES Following the PRISMA guidelines and the Cochrane protocol we conducted a systematic review on the management of an accessory or replaced right hepatic artery (RHA) arising from the superior mesenteric artery when performing an MIPD. RESULTS Five studies involving 118 patients were included. The most common reported management of the aberrant RHA was conservative (97.0%); however, patients undergoing aberrant RHA division without reconstruction did not develop liver or biliary complications. No differences in postoperative morbidity or long-term oncological related overall survival were reported in all the included studies when comparing MIPD in patients with standard anatomy to those with aberrant RHA. CONCLUSIONS MIPD in patients with aberrant RHA is feasible without increase in morbidity and mortality. As preoperative strategy is crucial, we suggested planning an MIPD with an anomalous RHA focusing on preoperative vascular aberrancy assessment and different strategies to reduce the risk of liver ischemia.

Abstract
We experienced 3 cases of port-access robot-assisted totally endoscopic technique for mitral valve repair and concomitant coronary artery bypass. The right internal mammary artery was harvested, mitral valve was fixed, and the right internal mammary artery to right coronary artery anastomosis was carried out on the arrested heart. The use of cardiac arrest and a V-shaped hook technique facilitated the coronary anastomosis and the da Vinci Firefly test (Intuitive Surgical Inc., Sunnyvale, CA) could confirm patency of the graft.

Abstract
ABSTRACT Malignant peritoneal mesothelioma is a rare malignancy that may manifest as extraperitoneal metastasis. We describe the findings of 68 Ga-FAPI and 18 F-FDG PET/CT in a case of malignant peritoneal mesothelioma with widespread muscle metastasis in a butterfly-shaped distribution pattern. We found that FDG and FAPI uptake in the peritoneal tumor and its spread were inhomogeneous. Notably, 68 Ga-FAPI PET/CT more clearly showed relevant lesions compared with 18 F-FDG PET/CT.

Abstract
BACKGROUND Laparoscopic appendectomy is one of the most common urgent pediatric surgical operations. Endoscopic surgical staplers and pre-tied endoloop ligatures are both routinely used for closure of the appendiceal stump in children. Practice patterns vary for a number of reasons, including cost, size, and ease of use. While stapling is standard for some pediatric surgeons, others believe that staples can act as a nidus for small bowel obstruction (SBO). However, studies comparing closure methods have been conflicting in their results and limited in size. Therefore, we aim to determine if there is an association between appendiceal stump closure method and SBO using a national comparative pediatric database. METHODS We queried the Pediatric Health Information System (PHIS) for patients ages 3-18 years who underwent laparoscopic appendectomy for appendicitis between 1/1/2016 - 12/31/2020. We included hospitals that had greater than 50 patients with billing data and excluded patients with inflammatory bowel disease and simultaneous abdominal operations. We used billing data for the patient's appendectomy to determine if a stapler or a suture ligature was used during the case. Our primary outcome of interest was post-operative SBO or reoperation for lysis of adhesion or intestinal surgery within the first 30 post-operative days. Multivariable regression analyses were used to estimate the association between stump closure method and post-operative SBO or reoperation in addition to cost while adjusting for patient demographics and appendiceal perforation. RESULTS In total, 49,191 patients from 37 hospitals were included, of which, 29,733 (60.44%) were male, 21,403 (43.51%) were non-Hispanic white, and 18,291 (37.18%) had a diagnosis of complicated appendicitis. The median [IQR] age of the cohort was 11 [8-14] years. A surgical stapler was used during laparoscopic appendectomy in 35,788 (72.75%) patients, and early SBO or reoperation occurred in 653 (1.33%) patients. In adjusted analysis controlling for demographics and complicated appendicitis there was no statistically significant difference in the odds of SBO or reoperation between the two groups. (OR 1.17; 99% CI 0.86 - 1.6). Complicated appendicitis was the factor most associated with post-operative SBO or reoperation (OR 4.4; 99% CI 3.01 - 6.44). Median cumulative cost was slightly higher on unadjusted analysis in the stapler group ($10,329.3 vs $9,569.2). However, there was no significant difference on adjusted analysis. CONCLUSION SBO or reoperation following laparoscopic appendectomy for appendicitis is uncommon. Complicated appendicitis is the most predictive factor of this outcome. Adjusting for available patient, disease, and hospital characteristics, use of a surgical stapler does not appear to be meaningfully associated with the development of acute SBO or reoperation. Surgeon preference remains the mainstay for safe appendiceal stump closure method. LEVEL OF EVIDENCE Level III. STUDY TYPE Retrospective Comparative Study.

Abstract
Imaging plays a critical role in the diagnosis and management of neuroendocrine tumors (NETs). The initial workup of the primary tumor, including its characterization, local and distant staging, defines subsequent treatment decisions. Functional imaging using hybrid systems, such as PET combined with computed tomography, has become the gold standard. As NETs majorly arise from the gastrointestinal system and metastasize primarily to the liver, simultaneous PET and MR imaging with its high soft tissue contrast might be a valuable clinical one-stop-shop whole-body imaging tool. This review presents the current status and challenges of PET/MR imaging for diagnosis of NETs.

Abstract
BACKGROUND Management of peri-operative bleeding is complex and involves multiple assessment tools and strategies to ensure optimal patient care with the goal of reducing morbidity and mortality. These updated guidelines from the European Society of Anaesthesiology and Intensive Care (ESAIC) aim to provide an evidence-based set of recommendations for healthcare professionals to help ensure improved clinical management. DESIGN A systematic literature search from 2015 to 2021 of several electronic databases was performed without language restrictions. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used to assess the methodological quality of the included studies and to formulate recommendations. A Delphi methodology was used to prepare a clinical practice guideline. RESULTS These searches identified 137 999 articles. All articles were assessed, and the existing 2017 guidelines were revised to incorporate new evidence. Sixteen recommendations derived from the systematic literature search, and four clinical guidances retained from previous ESAIC guidelines were formulated. Using the Delphi process on 253 sentences of guidance, strong consensus (>90% agreement) was achieved in 97% and consensus (75 to 90% agreement) in 3%. DISCUSSION Peri-operative bleeding management encompasses the patient's journey from the pre-operative state through the postoperative period. Along this journey, many features of the patient's pre-operative coagulation status, underlying comorbidities, general health and the procedures that they are undergoing need to be taken into account. Due to the many important aspects in peri-operative nontrauma bleeding management, guidance as to how best approach and treat each individual patient are key. Understanding which therapeutic approaches are most valuable at each timepoint can only enhance patient care, ensuring the best outcomes by reducing blood loss and, therefore, overall morbidity and mortality. CONCLUSION All healthcare professionals involved in the management of patients at risk for surgical bleeding should be aware of the current therapeutic options and approaches that are available to them. These guidelines aim to provide specific guidance for bleeding management in a variety of clinical situations.

Abstract
BACKGROUND Resection for colorectal liver metastases has evolved significantly and, currently, there are no limits to the number of resected nodules. This study aimed to evaluate the outcomes and prognostic factors after liver resection for patients with ≥4 colorectal liver metastases, emphasizing long-term survival. METHODS The study population consisted of 137 patients with ≥4 colorectal liver metastases out of a total of 597 patients with colorectal liver metastases who underwent curative intent liver resection from January 2010 to July 2019 in a single hepatobiliary center. RESULTS The probability of overall and disease-free survival at 1, 3, and 5 years was 90.8%, 64.5%, 40.6%, and 37.7%, 19.3%, 18.1%, respectively. In a multivariate analysis for overall survival, the size of the largest metastatic nodule was the only unfavorable factor (P = .001). For disease-free survival, complete pathological response was a favorable factor (P = .04), and the following were negative factors: number of nodules ≥7 (P = .034), radiofrequency ablation during surgery (P = .04), positive primary tumor lymph nodes (P = .034), R1 resection (P = .011), and preoperative carcinoembryonic antigen >20 ng/mL (P = .015). After the first and second years of follow-up, 59 patients (45.3%) and 45 patients (34.6%), respectively, were not receiving chemotherapy. After 5 years of follow-up, 21 (16.1%) multimetastatic patients were chemotherapy-free. CONCLUSION A significant number of patients with multiple colorectal liver metastases will present long-term survival and should not be denied surgery. The long-term survival rates, even in the presence of recurrence, characterize a chronic neoplastic disease.

Abstract
Pain is a common manifestation of several benign and malignant conditions. Inadequate response to conservative therapies is often succeeded by incremental use of analgesics and opioids; however, such an approach is often ineffective, not well tolerated by patients, and carries the risk of addiction leading to the opioid crisis. Implementing minimally invasive percutaneous procedures, performed by interventional radiologists has proven to be successful in providing safe, effective, and patient-specific therapies across a wide range of painful conditions. In the present narrative review, we will review the repertoire of minimally invasive imaging guided interventions, which have been successfully used to treat common painful benign and malignant conditions. We briefly describe each technique, common indications, and expected results.

Abstract
Severity grading systems for complications in surgical patients have been used since 1992. An increasing assessment of these instruments in pediatric surgery is also noticed, without their validation in children. To analyze the current practice, we performed a literature review with focus on the assessment and grading of complications. The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Studies reporting on postoperative complications as a primary or secondary endpoint using a severity grading system were included. Definition for simple adverse events, classification systems used, and the time horizon of postoperative documentation were analyzed. A total of 566 articles were screened, of which 36 met the inclusion criteria. About 86.1% of the papers were retrospective and 13.9% prospective analyses. None of the studies were prospective-randomized trials. Twenty (55.6%) studies did not include a definition of adverse events, whereas the remaining 16 (44.4%) showed variations in their definitions. All studies applied the Clavien-Dindo classification, whereas five (13.9%) additionally used the Comprehensive Complication Index. One study compared alternative grading instruments with the Clavien-Dindo classification, without demonstrating the superiority of any classification in pediatric surgery. Twenty-two studies (61.1%) did not report the time horizon of perioperative complication documentation, while 8 studies (22.2%) used 30 days and 6 studies (16.7%) used 3 months of postoperative documentation. Definition and classification of postoperative complications are inconsistent in the pediatric surgical literature. Establishment of a standardized protocol is mandatory to accurately compare outcome data.

Abstract
BACKGROUND Retroperitoneal sarcomas (RPS) are rare tumors for which surgical resection is the principal treatment. There is no established model to predict perioperative risks for RPS. We evaluated the association between preoperative sarcopenia, frailty, and hypoalbuminemia with surgical and oncological outcomes. METHODS We performed a prospective cohort analysis of 65 RPS patients who underwent surgical resection. Sarcopenia was defined as Total Psoas Area Index ≤ 1st quintile by sex. Frailty was estimated using the modified frailty index (mFI). Logistic regression models were used to assess predictors of 30-day postoperative morbidity. The Kaplan-Meier method with log-rank test was utilized to assess factors associated with overall (OS) and recurrence-free survival (RFS). RESULT Sarcopenia was associated with worse OS with a median of 54 compared with 158 months (p = 0.04), but no differences in RFS (p > 0.05). Hypoalbuminemia was associated with worse OS with a median of 72 compared with 158 months (p < 0.01). MFI scores were not associated with OS or RFS (p > 0.05). Sarcopenia, mFI, and hypoalbuminemia were not associated with postoperative morbidity (p > 0.05). CONCLUSION This study suggests that sarcopenia may be utilized as a measure of overall fitness, rather than a cancer-specific risk, and the mFI is a poor predictive measure of outcomes in RPS.

Abstract
BACKGROUND Enhanced recovery after surgery (ERAS) program has been proved to improve postoperative outcome for many surgical procedures, including liver resection. There was limited evidence regarding the feasibility and benefit of ERAS in patients who underwent liver resection for cholangiocarcinoma.
AIM To evaluate the feasibility of ERAS in patients who underwent liver resection for cholangiocarcinoma and its association with patient outcomes.
METHODS We retrospectively analyzed 116 cholangiocarcinoma patients who underwent hepatectomy at Srinagarind Hospital, Khon Kaen University between January 2015 and December 2016. The primary outcome was the compliance with ERAS. To determine the association between ERAS compliance and patient outcomes. the patients were categorized into those adhering more than and equal to 50% (ERAS ≥ 50), and below 50% (ERAS < 50) of all components. Details on type of surgical procedure, preoperative and postoperative care, tumor location, postoperative laboratory results, and survival time were evaluated. The compliance with ERAS was measured by the percentage of ERAS items achieved. The Kaplan-Meier curve was used for survival analysis.
RESULTS The median percentage of ERAS goals achieved was 40% (± 12%). Fourteen patients (12.1%) were categorized into the ERAS ≥ 50 group, and 102 patients were in the ERAS < 50 group. Postoperative hospital stay was significantly shorter in the ERAS ≥ 50 group [8.9 d, 95% confidence interval (CI): 7.3-10.4 d] than in the ERAS < 50 group (13.7 d, 95%CI: 12.2-15.2 d) (P = 0.0217). No hepatobiliary-related complications or in-hospital mortality occurred in the ERAS ≥ 50 group. Overall survival was significantly higher in the ERAS ≥ 50 group. The median survival of the patients in the ERAS < 50 group was 1257 d (95%CI: 853.2-1660.8 d), whereas that of the patients in the ERAS ≥ 50 group was not reached.
CONCLUSION Overall ERAS compliance for patients who underwent liver resection for cholangiocarcinoma is poor. Greater ERAS compliance could predict in-hospital, short-term, and long-term outcomes of the patients.

Abstract
Acute pancreatitis (AP) is a serious condition presenting catastrophic consequences. In severe AP, the mortality rate is high, and some patients initially diagnosed with mild-to-moderate AP can progress to a life-threatening severe state. Treatment of AP has evolved over the years. Drainage was the first surgical procedure performed for AP; however, later, surgical approaches were replaced by more conservative approaches due to the availability of advanced medical care and improved understanding of the course of AP. Currently, surgery is used to manage several complications of AP, such as pseudocysts, pancreatic fistulas, and biliary tract obstruction. Patients who are unresponsive to conservative treatment or have complications are typically considered for surgical intervention. This review focuses on the surgical approaches (endoscopic, percutaneous, and open) that have been established in recent studies to treat this acute condition and summarizes the common management guidelines for AP, discussing the relevant indications, significance, and complications. It is evident that despite their reduced involvement, surgeons lead the multidisciplinary care of patients with AP; however, given the gaps in existing knowledge, more research is required to standardize surgical protocols for AP.

Abstract
Situs inversus (SI) is a rare congenital condition characterized by a mirror-image transposition of the major visceral organs. Since the 1990s, more than one hundred SI patients have been reported to have successfully undergone laparoscopic cholecystectomy. In these cases, the major problem is to overcome is the left-right condition for right-handed surgeons. Laparoscopic common bile duct exploration (LCBDE), an alternative to treat patients with bile duct stones, has shown equivalent efficacy and is less likely to cause pancreatitis than endoscopic retrograde cholangiopancreatography. Recent updated meta-analyses revealed that a shorter postoperative hospital stay, fewer procedural interventions, cost-effectiveness, a higher stone clearance rate, and fewer perioperative complications are additional advantages of LCBDE. However, the technique is technically demanding, even for skilled laparoscopic surgeons. Conducting LCBDE in patients with difficult situations, such as SI, is more complex than usual. We herein review published SI patients with choledocholithiasis treated by LCBDE, including our own experience, and this paper focuses on the technical aspects.

Abstract
PURPOSE To examine the relationship between Neutrophil-Lymphocyte Ratio (NLR) and Acute Kidney Injury (AKI) in patients undergoing noncardiac surgery, and subgroup analysis was performed for different types of non-cardiac surgery. METHODS The present retrospective cohort study included 10,159 adult patients who underwent major noncardiac surgery at Nanfang Hospital, Southern Medical University, between 2008 and 2018. Postoperative AKI was defined as an increase in serum creatinine level of at least 0.3 mg/dl within 48 h, or 1.5 times higher than baseline within 7 days postoperatively according to the Kidney Disease Improving Global Outcome. The correlation between preoperative NLR and postoperative AKI was determined by stepwise multivariate logistic regression analysis, and the predictive value of NLR was evaluated by the receiver operating characteristics curve (ROC) analysis. RESULTS Four hundred and eighty-five (4.77%) patients developed AKI postoperatively. Preoperative NLR was independently associated with postoperative AKI in all patients undergoing non-cardiac surgery (Odds ratio [OR], 1.03; 95% confidence interval [CI], 1.00-1.06). The optimal cut-off value of NLR was 2.12 according ROC analysis. The OR and 95% CI of AKI for NLR > 2.12 was 1.48 (1.21-1.81) compared with NLR ≤ 2.12. In addition, the positive association was mainly shown in patients undergone digestive system surgery with a cut-off value of 2.12 but not in neurological and musculoskeletal system surgeries. CONCLUSION The present study confirmed the association of preoperative NLR with postoperative AKI in digestive system surgical patients. A NLR value of 2.12 may be a useful cut-off to evaluate the risk of AKI.

Abstract
BACKGROUND Systemic inflammation is recognized as a hallmark of cancer that contributes to tumor development and progression in various malignancies. The Naples prognostic score (NPS) was established as a prognostic indicator for colorectal cancer (CRC). This study aims to examine the predictive value of the NPS for survival in CRC patients undergoing curative resection by a propensity score matching (PSM) analysis. METHODS A total of 533 CRC patients were enrolled in this study. Overall survival (OS) and disease-free survival (DFS) were compared between high-NPS and low-NPS groups. A time-dependent receiver operator characteristic (ROC) curve analysis was conducted to calculate the area under curve (AUC) of the NPS for OS. A multivariable Cox-proportional hazards regression analysis and PSM analysis were used to identify independent prognostic factors for OS and DFS. We compared the predictive value of the NPS to that of the neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte ratio (PLR), Onodera prognostic nutritional index (PNI), and controlling nutritional status score (CONUT) for OS. RESULTS High-NPS was significantly associated with worse OS and DFS. After PSM, 123 patients were included in each group. A multivariate analysis revealed that Age ≥ 68, ASA-PS ≥ 3, high NPS and undifferentiated tumor type were independently associated with OS, while high NPS, advanced T and N stage were independently associated with DFS after PSM. The NPS had the greatest AUC for OS in comparison to the NLR, LMR, PNI and CONUT. CONCLUSIONS We successfully validated the prognostic utility of the NPS for CRC patients after curative resection.

Abstract
A Caucasian man in his late 80s was admitted with central abdominal pain, abdominal distension and continuous vomiting, on the background of a recent admission for acute cholecystitis. The patient was managed for subacute bowel obstruction and was admitted to general surgery for further investigation. His blood tests showed raised inflammatory markers and deranged liver function tests. A CT scan showed the migration of a large gallstone, previously seen in the neck of the gallbladder on prior admission, to the proximal duodenum causing a degree of gastric outlet obstruction. A diagnosis of Bouveret syndrome was made, and although initially managed conservatively, the patient ultimately underwent surgery to remove the gallstone which had relocated again to the terminal ileum. Our case highlights the importance of considering rare complications such as Bouveret syndrome in patients presenting with bowel obstruction, particularly in the context of recent or chronic cholecystitis.

Abstract
Background: As the population ages emergency surgeries among the elderly population, including colonic resections, is also increasing. Data regarding the short- and long-term outcomes in this population is scarce. Methods: A retrospective study was performed to investigate mortality and mortality risk factors associated with emergent colectomies in older compared to younger patients in a single university affiliated tertiary hospital. Patients with metastatic disease, colectomy due to trauma or index colectomy within 30 days prior to emergent surgery were excluded. Results: Operative outcomes compared among age groups, included 30-day mortality, mortality risk-factors and long-term survival. 613 eligible patients were included in the cohort. Mean age was 69.4 years, 45.1% were female. Patients were divided into four age groups: 18–59, 60–69, 70–79 and ≥80-years. Thirty-day mortality rates were 3.2%, 11%, 29.3% and 37.8%, respectively and 22% for the entire cohort. Risk-factors for perioperative death in the younger group were related to severity of ASA score and WBC count. In groups 60–69, 70–79, main risk-factors were ADL dependency and ASA score. In the ≥80 group, risk-factors affecting perioperative mortality, included ASA score, pre-operative albumin, creatinine, WBC levels, cancer etiology, ADL dependency, and dementia. Long-term survival differed significantly between age groups. Conclusion: Perioperative mortality with emergency colectomy increases with patients’ age. Patients older than eighty-years undergoing urgent colectomies have extremely high mortality rates, leading to a huge burden on medical services. Evaluating risk-factors for mortality and pre-operative discussion with patients and families is important. Screening the elderly population for colonic pathologies can result in early diagnosis potentially leading to elective surgeries with decreased mortality.

Abstract
Cystic dystrophy in heterotopic pancreas, or paraduodenal pancreatitis, is a rare and complicated presentation involving heterotopic pancreatic tissue in the duodenal wall. This condition is present in 5% of the general population but disease mainly affects middle-aged alcoholic-smoking men with chronic pancreatitis (CP). It may be purely duodenal or segmental (pancreatico-duodenopathy). Its pathophysiology arises from alcohol toxicity with obstruction of small ducts of heterotopic pancreatic tissue present in the duodenal wall and the pancreatic-duodenal sulcus, leading to repeated episodes of pancreatitis. The symptomatology includes episodes of acute pancreatitis, weight loss, and vomiting due to duodenal obstruction. Imaging shows thickening of the wall of the second portion of the duodenum with multiple small cysts. A stepwise therapeutic approach is preferred. Conservative medical treatment is favored in first intention (analgesics, continuous enteral feeding, somatostatin analogues), which allows complete symptomatic regression in 57% of cases associated with a 5% rate of complications (arterial thrombosis and diabetes). Endoscopic treatment may also be associated with conservative measures. Surgery achieves a complete regression of symptoms in 79% of cases but with a 20% rate of complications. Surgery is indicated in case of therapeutic failure or in case of doubt about a malignant tumor. Pancreaticoduodenectomy and duodenal resection with pancreatic preservation (PPDR) seem to be the most effective treatments. PPDR has also been proposed as a first-line treatment for purely duodenal location of paraduodenal pancreatitis, thereby preventing progression to an extended segmental form.

Abstract
Since hepatocellular carcinoma (HCC) represents an important cause of mortality and morbidity all over the world. Currently, it is fundamental not only to achieve a curative treatment but also to manage in the best way any possible recurrence. Even if the latest update of the Barcelona Clinic Liver Cancer guidelines for HCC treatment has introduced new locoregional techniques and confirmed others as well-established clinical practices, there is still no consensus about the treatment of recurrent HCC (RHCC). Locoregional treatments and medical therapy represent two of the most widely accepted approaches for disease control, especially in the advanced stage of liver disease. Different medical treatments are now approved, and others are under investigation. On this basis, radiology plays a central role in the diagnosis of RHCC and the assessment of response to locoregional treatments and medical therapy for RHCC. This review summarized the actual clinical practice by underlining the importance of the radiological approach both in the diagnosis and treatment of RHCC.

Abstract
BACKGROUND Eosinophilic gastrointestinal disease (EGID) is a disorder characterized by infiltration of eosinophils causing mucosal damage and dysfunction of the gastrointestinal tract. The endoscopic findings of eosinophilic enteritis (EoN), an EGID variant, are nonspecific and occasionally difficult to diagnose. In contrast, chronic enteropathy associated with SLCO2A1 (CEAS) is a chronic persistent small intestinal disorder characterized by endoscopic findings such as multiple oblique and circular ulcers.
CASE SUMMARY We report the case of a 10-year-old boy who had suffered abdominal pain and fatigue for the preceding 6 mo. He was referred to our institute for investigation of suspected gastrointestinal bleeding because of severe anemia with hypoproteinemia and positive fecal human hemoglobin. The upper and lower gastrointestinal endoscopic findings were normal; however, double-balloon small bowel endoscopy showed multiple oblique and circular ulcers with discrete margins and mild constriction of the intestinal lumen in the ileum. The findings were highly consistent with CEAS, but urine prostaglandin metabolites were within normal limits, and no previously reported mutations in the SLCO2A1 gene were identified. Histological evaluation demonstrated moderate to severe eosinophilic infiltration localized to the small intestine suggesting a diagnosis of EoN. Clinical remission was maintained with montelukast and a partial elemental diet, but emergent surgery for bowel obstruction due to small intestinal stenosis was performed two years after the initial treatment.
CONCLUSION EoN should be considered in the differential diagnosis of CEAS-like small intestinal ulcerative lesions and normal urinary prostaglandin metabolite levels.

Abstract
BACKGROUND Perforated peptic ulcer (PPU) remain a surgical emergency accounting for 37% of all peptic ulcer-related deaths. Surgery remains the standard of care. The benefits of laparoscopic approach have been well-established even in the elderly. However, because of inconsistent results with specific regard to some technical aspects of such technique surgeons questioned the adoption of laparoscopic approach. This leads to choose the type of approach based on personal experience. The aim of our study was to critically appraise the use of the laparoscopic approach in PPU treatment comparing it with open procedure. METHODS A retrospective study with propensity score matching analysis of patients underwent surgical procedure for PPU was performed. Patients undergoing PPU repair were divided into: Laparoscopic approach (LapA) and Open approach (OpenA) groups and clinical-pathological features of patients in the both groups were compared. RESULTS A total of 453 patients underwent PPU simple repair. Among these, a LapA was adopted in 49% (222/453 patients). After propensity score matching, 172 patients were included in each group (the LapA and the OpenA). Analysis demonstrated increased operative times in the OpenA [OpenA: 96.4 ± 37.2 vs LapA 88.47 ± 33 min, p = 0.035], with shorter overall length of stay in the LapA group [OpenA 13 ± 12 vs LapA 10.3 ± 11.4 days p = 0.038]. There was no statistically significant difference in mortality [OpenA 26 (15.1%) vs LapA 18 (10.5%), p = 0.258]. Focusing on morbidity, the overall rate of 30-day postoperative morbidity was significantly lower in the LapA group [OpenA 67 patients (39.0%) vs LapA 37 patients (21.5%) p = 0.002]. When stratified using the Clavien-Dindo classification, the severity of postoperative complications was statistically different only for C-D 1-2. CONCLUSIONS Based on the present study, we can support that laparoscopic suturing of perforated peptic ulcers, apart from being a safe technique, could provide significant advantages in terms of postoperative complications and hospital stay.

Abstract
OBJECTIVE Because pregnancy outcomes tend to be worse in women with inflammatory bowel disease (IBD) than in those without, we aimed to update consensus statements that guide the clinical management of pregnancy in patients with IBD. DESIGN A multidisciplinary working group was established to formulate these consensus statements. A modified RAND/UCLA appropriateness method was used, consisting of a literature review, online voting, discussion meeting and a second round of voting. The overall agreement among the delegates and appropriateness of the statement are reported. RESULTS Agreement was reached for 38/39 statements which provide guidance on management of pregnancy in patients with IBD. Most medications can and should be continued throughout pregnancy, except for methotrexate, allopurinol and new small molecules, such as tofacitinib. Due to limited data, no conclusion was reached on the use of tioguanine during pregnancy. Achieving and maintaining IBD remission before conception and throughout pregnancy is crucial to optimise maternofetal outcomes. This requires a multidisciplinary approach to engage patients, allay anxieties and maximise adherence tomedication. Intestinal ultrasound can be used for disease monitoring during pregnancy, and flexible sigmoidoscopy or MRI where clinically necessary. CONCLUSION These consensus statements provide up-to-date, comprehensive recommendations for the management of pregnancy in patients with IBD. This will enable a high standard of care for patients with IBD across all clinical settings.

Abstract
In malignant pheochromocytoma, the survival benefit of metastasectomy remains unclear. However, excessive catecholamines secreted from pheochromocytomas can cause cardiovascular and cerebrovascular complications. Debulking metastasectomy can be performed to reduce excess catecholamine secretion when curative resection is impossible. We present a case of metastatic pheochromocytoma to the liver, wherein a significant reduction in catecholamine secretion was achieved by repeat debulking hepatectomy. A 62-year-old woman who had undergone left adrenalectomy for primary pheochromocytoma 10 years prior to our surgical management, had multiple liver metastases of pheochromocytoma. Curative hepatectomy was infeasible because of insufficient remnant liver volume; thus, debulking hepatectomy was conducted. Preoperatively, increased doses of alpha-blockers and catecholamine synthesis inhibitors were administered. Nevertheless, substantial fluctuations in blood pressure and massive hemorrhage were observed intraoperatively. Eight months after the initial hepatectomy, repeat hepatectomy for the remnant lesions was performed due to the worsening of catecholamine levels and catecholamine-related symptoms. The patient survived, with serum catecholamines remaining within the normal range after repeat hepatectomy. Repeat debulking hepatectomy for metastatic pheochromocytoma to the liver is a feasible treatment strategy to effectively decrease catecholamine secretion and alleviate the symptoms thereof. However, special attention should be paid to perioperative catecholamine management and intraoperative surgical techniques.

Abstract
PURPOSE Few studies are available on older patients with acute cholangitis. In this study, we aimed to examine the clinical characteristics of older patients with acute cholangitis. METHODS Patients aged 65 years and over who were diagnosed with acute cholangitis between February 2019 and August 2022 were analyzed retrospectively. Patients eligible for the study were divided into two groups as those aged ≥ 80 years (octogenarian) and those aged 65-79 years (non-octogenarian). These two groups were then compared for many clinical characteristics. In addition, factors associated with in-hospital mortality were identified. Finally, a subgroup analysis was performed in patients with non-malignant etiology. RESULTS Of a total of 309 enrolled patients, 120 (38.8%) were in the octogenarian group and 189 (61.2%) were in the non-octogenarian group. The mean age was 77.2 ± 8.0 years and 51.8% were women. Severe disease and intensive care unit admission rates were higher in the octogenarian group (p = 0.035 and p = 0.002, respectively), but there was no significant difference in the rate of in-hospital mortality (p = 0.146). Malignant etiology (OR 2.990, 95% CI 1.131-7.904) and hypoalbuminemia (OR 0.824, 95% CI 0.751-0.903) were independent risk factors for in-hospital mortality. In the subgroup analysis of non-malignant etiology, the octogenarian group had a significantly higher in-hospital mortality rate than the non-octogenarian group (8.8% vs. 3.2%, p = 0.048). CONCLUSIONS Among older patients with acute cholangitis, clinicians should closely monitor those aged 80 years and over, as well as those with malignant etiology and hypoalbuminemia, due to their high risk of serious clinical events.

Abstract
Diagnosis of extrapulmonary forms of tuberculosis is still challenging. Abdominal tuberculosis has no pathogno- monic signs, so most patients had various diagnoses. In this clinical case, the diagnostic difficulties are due to the absence of a history of tuberculosis and the manifestation of the isolated tuberculosis process in the intestine. This forced us for a wide differential diagnostic search to exclude inflammatory bowel diseases and neoplasms and required the multidisciplinary team. This approach, awareness and alertness of specialists regarding extrapulmonary forms of tuberculosis made it possible to achieve success in this patient.

Abstract
BACKGROUND Anthracosis is a disease generally considered to be in the lungs resulting from exposure to industrial dust in the workplace. Esophageal anthracosis is a fairly rare phenomenon and shows a strong correlation with tuberculosis. Moreover, esophageal involvement in tuberculosis is also rare. We here present an extremely rare case in which follow-up gastroesophageal endoscopy revealed a mass with a sunken, black area in the center and raised ring-like pattern in the surrounding mucosa resembling malignant melanoma. Uncovering the patient's tuberculosis history finally avoided a misdiagnosis or overtreatment. CASE PRESENTATION A 67-year-old male patient was admitted to the hospital due to "repeated chest pain for 1 month". Endoscopic ultrasonography and contrast-enhanced CT scans revealed a mass adjacent to the esophageal wall with unclear boundaries. Aspiration biopsy confirmed that esophageal tuberculosis was caused by nearby mediastinal tuberculous lymphadenitis. After a standard anti-tuberculosis treatment regimen, the patient achieved a favorable prognosis. The follow-up gastroesophageal endoscopy showed a sunken black lesion with elevated peripheral mucosa replacing the original tuberculous mass, which was thought to be anthracosis, a disease that rarely occurs in the esophagus. CONCLUSION The diagnosis of tuberculosis should be taken into consideration when a submucosal mass appears in the middle part of the esophagus. Endoscopic ultrasonography can effectively contribute to a definite diagnosis. Moreover, this is the first case of esophageal anthracosis observed only 1 year after the treatment of tuberculosis, indicating esophageal anthracosis can be a short-term disease. The traction of the reduction of tubercular mediastinal lymph nodes after anti-tuberculosis treatment may create a circumstance for pigmentation or dust deposition.

Abstract
Inflammasomes, composed of the nucleotide-binding oligomerization domain(NOD)-like receptors (NLRs), are immune-functional protein multimers that are closely linked to the host defense mechanism. When NLRs sense pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs), they assemble into inflammasomes. Inflammasomes can activate various inflammatory signaling pathways, including nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways, and produce a large number of proinflammatory cytokines, which are closely associated with multiple cancers. They can also accelerate the occurrence and development of cancer by providing suitable tumor microenvironments, promoting tumor cell proliferation, and inhibiting tumor cell apoptosis. Therefore, the exploitation of novel targeted drugs against various inflammasomes and proinflammatory cytokines is a new idea for the treatment of cancer. In recent years, more than 50 natural extracts and synthetic small molecule targeted drugs have been reported to be in the research stage or have been applied to the clinic. Herein, we will overview the mechanisms of inflammasomes in common cancers and discuss the therapeutic prospects of natural extracts and synthetic targeted agents.

Abstract
Background: The primary aim of this study was to create a machine learning (ML) model that can predict perforated and nonperforated acute appendicitis (AAp) with high accuracy and to demonstrate the clinical interpretability of the model with explainable artificial intelligence (XAI). Method: A total of 1797 patients who underwent appendectomy with a preliminary diagnosis of AAp between May 2009 and March 2022 were included in the study. Considering the histopathological examination, the patients were divided into two groups as AAp (n = 1465) and non-AAp (NA; n = 332); the non-AAp group is also referred to as negative appendectomy. Subsequently, patients confirmed to have AAp were divided into two subgroups: nonperforated (n = 1161) and perforated AAp (n = 304). The missing values in the data set were assigned using the Random Forest method. The Boruta variable selection method was used to identify the most important variables associated with AAp and perforated AAp. The class imbalance problem in the data set was resolved by the SMOTE method. The CatBoost model was used to classify AAp and non-AAp patients and perforated and nonperforated AAp patients. The performance of the model in the holdout test set was evaluated with accuracy, F1- score, sensitivity, specificity, and area under the receiver operator curve (AUC). The SHAP method, which is one of the XAI methods, was used to interpret the model results. Results: The CatBoost model could distinguish AAp patients from non-AAp individuals with an accuracy of 88.2% (85.6–90.8%), while distinguishing perforated AAp patients from nonperforated AAp individuals with an accuracy of 92% (89.6–94.5%). According to the results of the SHAP method applied to the CatBoost model, it was observed that high total bilirubin, WBC, Netrophil, WLR, NLR, CRP, and WNR values, and low PNR, PDW, and MCV values increased the prediction of AAp biochemically. On the other hand, high CRP, Age, Total Bilirubin, PLT, RDW, WBC, MCV, WLR, NLR, and Neutrophil values, and low Lymphocyte, PDW, MPV, and PNR values were observed to increase the prediction of perforated AAp. Conclusion: For the first time in the literature, a new approach combining ML and XAI methods was tried to predict AAp and perforated AAp, and both clinical conditions were predicted with high accuracy. This new approach proved successful in showing how well which demographic and biochemical parameters could explain the current clinical situation in predicting AAp and perforated AAp.

Abstract
BACKGROUND Methylene blue staining of the resected specimen has been described as an alternative to the conventional palpation and visual inspection method to improve lymph node harvest. This meta-analysis evaluates the usefulness of this technique in surgery for rectal cancer, particularly after neoadjuvant therapy. METHODS Randomized controlled trials (RCTs) comparing lymph node harvest in methylene blue-stained rectal specimens to those of unstained specimens were identified from the Medline, Embase, and Cochrane databases. Non-randomized studies and those with only colonic resections were excluded. The quality of RCTs was assessed using Cochrane's risk of bias tool. A weighted mean difference (WMD) was calculated for overall harvest, harvest after neoadjuvant therapy, and metastatic nodal yield. In contrast, the risk difference (RD) was calculated to compare yields of less than 12 lymph nodes between the stained and unstained specimens. RESULTS Study selection comprised seven RCTs with 343 patients in the unstained group and 337 in the stained group. Overall lymph node harvest and harvest after neoadjuvant therapy were significantly higher in stained specimens with a WMD of 13.4 and 10.6 and a 95% confidence interval (CI) of 9.5-17.2 and 4.8-16.3, respectively. Harvest of metastatic lymph nodes was significantly higher in the stained group (WMD 1.0, 95% CI 0.6-1.4). The yield of less than 12 lymph nodes was significantly higher in the unstained group with RD of 0.292 and 95% CI of 0.182-0.403. CONCLUSION Despite a small number of patients, this meta-analysis confirms improved lymph node harvest in surgical specimens stained with methylene blue compared with unstained specimens.

Abstract
BACKGROUND AND AIMS Despite the advances in medical therapies, a significant proportion of patients with inflammatory bowel diseases [IBD] require surgical intervention. This Topical Review aims to offer expert consensus practice recommendations for peri-operative care to optimize outcomes of IBD patients who undergo surgery. METHODS A multidisciplinary panel of IBD healthcare providers systematically reviewed aspects relevant to peri-operative care in IBD. Consensus statements were developed using Delphi methodology. RESULTS A total of 20 current practice positions were developed following systematic review of the current literature covering use of medication in the peri-operative period, nutritional assessment and intervention, physical and psychological rehabilitation and prehabilitation, and immediate postoperative care. CONCLUSION Peri-operative planning and optimization of the patient are imperative to ensure favourable outcomes and reduced morbidity. This Topical Review provides practice recommendations applicable in the peri-operative period in IBD patients undergoing surgery.

Abstract
BACKGROUND The adoption and accessibility of laparoscopy have been serious issues in countries with limited resources, and for varied reasons. This study assessed resource capacity and barriers to the effective practice of laparoscopic surgery in training hospitals affiliated with the College of Surgeons of East, Central and Southern Africa (COSECSA). METHODS A multi-country survey was conducted from January 2021 to October 2021 using a questionnaire distributed to surgeons in COSECSA hospitals located in 16 different countries. Available resources and surgical volume were assessed, and the barriers to routinely performing laparoscopy were determined. RESULTS Ninety-four surgeons working in 44 different hospitals from 16 countries participated in the survey. The majority of respondents were general surgeons (n = 75, 79.7%). Other specialties included urology (n = 12, 12.8%) and pediatric surgery (n = 7, 7.4%). Senior surgeons accounted for 60.6% of participants, more than 40% had a managerial position and approximately 20% were surgical trainees. Most respondents practiced in public hospitals (n = 66, 70.2%). A median of three surgeons per hospital performed laparoscopic surgery with, on average, two laparoscopic towers and two sets of laparoscopic instruments available. A median of 10 procedures was carried out per month. The cost of laparoscopic procedures and laparoscopic consumables were reported as being covered by some health insurance payments in 76.9% and 48.4% of cases, respectively. Cholecystectomy was the most commonly reported laparoscopic procedure performed. The five top barriers to performing laparoscopic surgery were: a lack of consumables, a limited quantity of equipment, a lack of skilled surgeons, the high cost of laparoscopic procedures and complicated cases. In addition, having access to skilled anesthesiologists and anesthesia equipment, carbon dioxide, a consistent electric power supply and equipment maintenance were cited as significant challenges. CONCLUSION The practice of laparoscopy is currently limited in COSECSA countries due to a scarcity of skilled staff and the lack of a funding plan to make laparoscopic services accessible. Therefore, policymakers and stakeholders should take strategic measures to respond to this need.
