Prognostic Value of Liver Biomarkers in Hepatocellular Carcinoma Patients Undergoing Yttrium 90 Transarterial Radioembolization (TARE): A Retrospective Pilot Study.

INTRODUCTION: Hepatocellular carcinoma (HCC) is a common cause of cancer-related death worldwide. The prognosis for HCC depends on the tumor stage, and curative therapies are more accessible in the early stages. However, effective treatments are available even in advanced stages. Transarterial radioembolization (TARE) is an alternative to transarterial chemoembolization (TACE) with reduced risk and extended disease progression time. Identifying prognostic indicators and treatment response biomarkers remains crucial. The purpose of this study was to assess the association between biomarkers related to fibrosis, liver function, and immune inflammation with tumor response to yttrium 90 transarterial radiotherapy (Y90 or TARE) in patients with HCC. METHODS: This study enrolled patients who underwent Y90 radiotherapy for bridging, downstaging, or palliative treatment after discussion in a multidisciplinary tumor board. Using the modified Response Evaluation Criteria in Solid Tumors (mRECIST), tumor response was classified into two groups: "responders" (complete and partial response) and "non-responders" (stable and progressive disease). Logistic regression analysis was used to evaluate the association between predictors, biomarkers such as aspartate aminotransferase (AST)-to-platelet ratio index (APRI), fibrosis-4 (FIB-4), albumin-bilirubin (ALBI) score, model for end-stage liver disease (MELD) score, MELD sodium, and the systemic immune-inflammatory indexes, at established cut-offs and tumor response. RESULTS: Of 35 patients, 22 (63%) were Whites and non-Hispanics, 32 (91%) were diagnosed with cirrhosis, and 14 (40%) of these had a viral etiology. According to mRECIST, 18 (51%) patients were classified as "responders." In multivariable logistic regression analysis, biomarkers associated with tumor response were ALBI score ≤-2.8 (odds ratio (OR) 6.1, 95%CI 2.7-14.4) and the neutrophil-to-lymphocyte ratio (NLR) ≤ 1.92 (OR 5.1, 95%CI 0.8-11.9). Biomarkers had moderate accuracy in predicting tumor response (C-statistic 0.75). CONCLUSION: The ALBI score is a reliable predictor of treatment response following TARE. The NLR index may offer further prognostic information, and both biomarkers can be used in combination; however, further research in larger sample sets is needed.

Incidence and Temporal Evolution of Delayed Peridevice Leak After Left Atrial Appendage Closure.

BACKGROUND: Peridevice leak (PDL) following left atrial appendage closure (LAAC) portends adverse outcomes. OBJECTIVE: To assess the incidence, predictors, clinical implications, and temporal evolution of PDL following LAAC. METHODS: This single-center retrospective study included all patients who underwent LAAC with Watchman FLX and had no PDL detected at implant. The primary endpoint was incidence of new PDL at initial imaging. The composite secondary endpoint included continued oral anticoagulation after initial imaging, device-related thrombus, stroke or transient ischemic attack, major bleeding, and need for PDL closure at longest follow-up. Temporal evolution of PDL was assessed in patients with available surveillance imaging. RESULTS: Among 355 patients who completed imaging at 47 (IQR 6) days, 139 (39%) had a new PDL with a mean leak size of 3.2±1.4 [median 3.0 (IQR 2.0), and range 1.0-9.0 mm]. Multiple deployment attempts and larger device size were positive predictors of PDL, while increased contrast volume administration was a negative predictor of PDL. The composite secondary endpoint occurred in 42 (30%) and 33 (15%) patients with and without PDL respectively (p<0.001). Among the 139 patients with PDL, 43 (31%) had surveillance imaging where leak size regressed from 3.7±1.8mm at 46 (IQR 7) days to 1.7±2.0mm at 189 (IQR 127) days (p<0.001). The leak size regressed in 33 (77%), remained stable in 4 (9%), and progressed in 6 (14%) cases. CONCLUSION: Despite design improvements, LAAC with Watchman FLX demonstrates significant incidence of PDL with meaningful clinical implications. Regardless of initial size, most leaks regressed over time.

Emergent facilitation and glassy dynamics in supercooled liquids.

In supercooled liquids, dynamical facilitation refers to a phenomenon where microscopic motion begets further motion nearby, resulting in spatially heterogeneous dynamics. This is central to the glassy relaxation dynamics of such liquids, which show super-Arrhenius growth of relaxation timescales with decreasing temperature. Despite the importance of dynamical facilitation, there is no theoretical understanding of how facilitation emerges and impacts relaxation dynamics. Here, we present a theory that explains the microscopic origins of dynamical facilitation. We show that dynamics proceeds by localized bond-exchange events, also known as excitations, resulting in the accumulation of elastic stresses with which new excitations can interact. At low temperatures, these elastic interactions dominate and facilitate the creation of new excitations near prior excitations. Using the theory of linear elasticity and Markov processes, we simulate a model, which reproduces multiple aspects of glassy dynamics observed in experiments and molecular simulations, including the stretched exponential decay of relaxation functions, the super-Arrhenius behavior of relaxation timescales as well as their two-dimensional finite-size effects. The model also predicts the subdiffusive behavior of the mean squared displacement (MSD) on short, intermediate timescales. Furthermore, we derive the phonon contributions to diffusion and relaxation, which when combined with the excitation contributions produce the two-step relaxation processes, and the ballistic-subdiffusive-diffusive crossover MSD behaviors commonly found in supercooled liquids.

A Geospatial Analysis of the Availability, Distribution, and Accessibility of Neurosurgical Facilities, Workforce, and Infrastructure in Nigeria; and Projection Towards 2050.

OBJECTIVE: There has been a modest but progressive increase in the neurosurgical workforce, training, and service delivery in Nigeria in the last 2 decades. However, these resources are unevenly distributed. This study aimed to quantitatively assess the availability and distribution of neurosurgical resources in Nigeria while projecting the needed workforce capacity up to 2050. METHODS: An online survey of Nigerian neurosurgeons and residents assessed the country's neurosurgical infrastructure, workforce, and resources. The results were analyzed descriptively, and geospatial analysis was used to map their distribution. A projection model was fitted to predict workforce targets for 2022-2050. RESULTS: Out of 86 neurosurgery-capable health facilities, 65.1% were public hospitals, with only 17.4% accredited for residency training. Dedicated hospital beds and operating rooms for neurosurgery make up only 4.0% and 15.4% of the total, respectively. The population disease burden is estimated at 50.2 per 100,000, while the operative coverage was 153.2 cases per neurosurgeon. There are currently 132 neurosurgeons and 114 neurosurgery residents for a population of 218 million (ratio 1:1.65 million). There is an annual growth rate of 8.3%, resulting in a projected deficit of 1113 neurosurgeons by 2030 and 1104 by 2050. Timely access to neurosurgical care ranges from 21.6% to 86.7% of the population within different timeframes. CONCLUSIONS: Collaborative interventions are needed to address gaps in Nigeria's neurosurgical capacity. Investments in training, infrastructure, and funding are necessary for sustainable development and optimized outcomes.

Threat sensitivity in emotion dynamics: Negativity effects and sex differences.

Evolutionary theorizing has given rise to the idea that responding to any particular threat may be more mandatory than responding to any particular reward. The present three experiments (total N = 375) sought to provide support for this perspective in an emotion dynamics task in which participants continuously rated their affective state in response to appetitive (reward-related) versus aversive (threat-related) images. Even when equating images for arousal and extremity, several negativity effects (e.g., steeper reactivity slopes in response to aversive images) were found. These negativity effects can serve as an experimental model of threat sensitivity, which should predispose some individuals, more than others, to symptoms related to fear and anxiety. This point was made with respect to sex differences, given that women (relative to men) are diagnosed with anxiety disorders at higher rates. Sex differences were pronounced and extensions of this work, both basic and applied, are proposed.

Preparation, In Vitro Characterization, and Evaluation of Polymeric pH-Responsive Hydrogels for Controlled Drug Release.

The purpose of the current research is to formulate a smart drug delivery system for solubility enhancement and sustained release of hydrophobic drugs. Drug solubility-related challenges constitute a significant concern for formulation scientists. To address this issue, a recent study focused on developing PEG-g-poly(MAA) copolymeric nanogels to enhance the solubility of olmesartan, a poorly soluble drug. The researchers employed a free radical polymerization technique to formulate these nanogels. Nine formulations were formulated. The newly formulated nanogels underwent comprehensive tests, including physicochemical assessments, dissolution studies, solubility evaluations, toxicity investigations, and stability examinations. Fourier transform infrared (FTIR) investigations confirmed the successful encapsulation of olmesartan within the nanogels, while thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) studies verified their thermal stability. Scanning electron microscopy (SEM) images revealed the presence of pores on the surface of the nanogels, facilitating water penetration and promoting rapid drug release. Moreover, powder X-ray diffraction (PXRD) studies indicated that the prepared nanogels exhibited an amorphous structure. The nanogel carrier system led to a significant enhancement in olmesartan's solubility, achieving a remarkable 12.3-fold increase at pH 1.2 and 13.29-fold rise in phosphate buffer of pH 6.8 (NGP3). Significant swelling was observed at pH 6.8 compared to pH 1.2. Moreover, the formulated nexus is nontoxic and biocompatible and depicts considerable potential for delivery of drugs and protein as well as heat-sensitive active moieties.

TGF-ß blockade drives a transitional effector phenotype in T cells reversing SIV latency and decreasing SIV reservoirs in vivo.

HIV-1 persistence during ART is due to the establishment of long-lived viral reservoirs in resting immune cells. Using an NHP model of barcoded SIVmac239 intravenous infection and therapeutic dosing of anti-TGFBR1 inhibitor galunisertib (LY2157299), we confirm the latency reversal properties of in vivo TGF-ß blockade, decrease viral reservoirs and stimulate immune responses. Treatment of eight female, SIV-infected macaques on ART with four 2-weeks cycles of galunisertib leads to viral reactivation as indicated by plasma viral load and immunoPET/CT with a 64Cu-DOTA-F(ab')2-p7D3-probe. Post-galunisertib, lymph nodes, gut and PBMC exhibit lower cell-associated (CA-)SIV DNA and lower intact pro-virus (PBMC). Galunisertib does not lead to systemic increase in inflammatory cytokines. High-dimensional cytometry, bulk, and single-cell (sc)RNAseq reveal a galunisertib-driven shift toward an effector phenotype in T and NK cells characterized by a progressive downregulation in TCF1. In summary, we demonstrate that galunisertib, a clinical stage TGF-ß inhibitor, reverses SIV latency and decreases SIV reservoirs by driving T cells toward an effector phenotype, enhancing immune responses in vivo in absence of toxicity.

Pd-Catalyzed Oxidative C-H Arylation of (Poly)fluoroarenes with Aryl Pinacol Boronates and Experimental and Theoretical Studies of its Reaction Mechanism.

We report the synergistic combination of Pd(OAc)2 and Ag2O for the oxidative C-H arylation of (poly)fluoroarenes with aryl pinacol boronates (Ar-Bpin) in DMF as the solvent. This procedure can be conducted easily in air, and without using additional ligands, to afford the fluorinated unsymmetrical biaryl products in up to 98 % yield. Experimental studies suggest that the formation of [PdL2(C6F5)2] in DMF as coordinating solvent does not take place under the reaction conditions as it is stable to reductive elimination and thus would deactivate the catalyst. Thus, the intermediate [Pd(DMF)2(ArF)(Ar)] must be formed selectively to give desired arylation products. DFT calculations predict a low barrier (5.87 kcal/mol) for the concerted metalation deprotonation (CMD) process between C6F5H and the Pd(II) species formed after transmetalation between the Pd(II)X2 complex and aryl-Bpin which forms a Pd-Arrich species. Thus a Pd(Arrich)(Arpoor) complex is generated selectively which undergoes reductive elimination to generate the unsymmetrical biaryl product.

Pilot study of the implementation of G8 screening tool, Cognitive screening assessment and Chemotherapy Toxicity assessment in older adults with cancer in a Tertiary University Hospital in Ireland.

BACKGROUND: Comprehensive geriatric assessment (CGA) is recommended by international guidelines prior to initiation of systemic anti-cancer treatment (SACT). In practice, CGA is limited by time constraints, lack of resources and expert interpretation. AIMS: The primary objective of this pilot study was to establish the prevalence of frailty (assessed by G8), cognitive impairment (assessed by Mini-Cog), and risk of chemotherapy toxicity (assessed by CARG Chemo-Toxicity Calculator) among patients (pts) ≥65 years commencing SACT. We selected these three screening tools due to the ease of conducting them in a busy outpatient setting. In addition, they have been validated to predict frailty and risk of toxicity from SACT among older adults with cancer. METHODS: Eligible participants were identified from medical oncology clinics. Assessments were conducted in an outpatient setting by treating physicians. Pt records were reviewed to gather demographic and cancer details. Statistical analyses were conducted using SPSS statistical software. RESULTS: Sixty-three participants were enrolled. The mean age of participants was 73yrs (range=65-88). Thirty-three (52.4%) were female and 30 (47.6%) were male. The majority (n=38, 60.3%) had metastatic cancer. The mean G8 score was 11.9 (range=6-19). Eighty-three percent had a G8 score ≤14. Mini-Cog was positive in 13 pts (21%). The mean CARG score was 7.5 (range=0-16), and 80% had a risk of at least 50% grade ≥3 toxicity. Of these, 48 (76.2%) received chemotherapy and 15 (23.8%) received non-cytotoxic SACT. In multi-variate analyses, age, cancer type, treatment type, and disease stage did not impact G8, Mini-Cog, or CARG scores. CONCLUSIONS: Our study has several limitations but suggests that the majority of older adults with cancer would qualify for formal CGA assessment. The risk of high-grade toxicity from SACT is substantial in this cohort. Chronological age was not found to negatively impact pts' frailty, cognition, or risk of toxicity.

Molecular characterization of Aeromonas hydrophila isolates from diseased fishes in district Kasur, Punjab, Pakistan / Caracterização molecular de isolados de Aeromonas hydrophila de peixes doentes no distrito de Kasur, Punjab, Paquistão

Abstract Pakistan is an agricultural country and fisheries play a very important role in the economic development of the country. Different diseases are prevalent in Pakistani fish but information related to the causative agents is not well-known. Keeping in view the significance of bacterial pathogens as the causative agents of multiple fish diseases, the present study was conducted for identification, characterization and analysis of virulence genes of Aeromonas spp. isolated from diseased fishes. A total of fifty fish samples having multiple clinical indications were collected from different fish farms of district Kasur, Punjab Pakistan. For isolation of Aeromonas spp. samples were enriched and inoculated on Aeromonas isolation medium. Isolates were identified and characterized by different biochemical tests, Analytical Profile Index (API) 20E kit and Polymerase Chain Reaction (PCR) assays. All isolates were screened for three putative virulence genes including aerolysin (aer), haemolysin (hyl) and heat labile cytotonic enterotoxin (alt). Seven isolates of Aeromonas (A.) hydrophila were retrieved and identified based on API 20E. These isolates were further confirmed as A. hydrophila on the basis of PCR assays. Three isolates were detected positive for the presence of virulence genes (alt and hyl). Whereas aerolysin (aer) gene was not present in any of A. hydrophila isolates. The present study confirmed A. hydrophila as the causative agent of epizootic ulcerative syndrome and motile Aeromonas septicemia in fish farms of district Kasur, Punjab Pakistan. Moreover, detection of two virulence genes (alt and hyl) in A. hydrophila isolates is a threat for fish consumers of study area.

Haemophilus influenzae Bacteremia and Pneumonia: A Case Report.

This study reports a case of respiratory failure and pneumonia attributed to infection from a confirmed case of Haemophilus influenzae in a patient with past medical history of interstitial lung disease following a COVID-19 infection. An 88-year-old man with significant past medical history of interstitial lung disease (ILD) and self-catheterization due to benign prostatic hyperplasia (BPH) presented to the ED with shortness of breath and cough. Examination revealed reduced respiratory effort and scattered rhonchi throughout the lung fields. Urine cultures were positive for extended spectrum beta-lactamase (ESBL) Escherichia coli. In addition, blood cultures and chest X-ray findings confirmed a case of H. influenzae bacteremia and pneumonia. The following case highlights the unusual finding of invasive H. influenzae disease and corresponds with the data provided by the Active Bacterial Core surveillance supported by the Centers for Disease Control and Prevention (CDC).

TGF-ß blockade drives a transitional effector phenotype in T cells reversing SIV latency and decreasing SIV reservoirs in vivo.

HIV-1 persistence during ART is due to the establishment of long-lived viral reservoirs in resting immune cells. Using an NHP model of barcoded SIVmac239 intravenous infection and therapeutic dosing of the anti-TGFBR1 inhibitor galunisertib (LY2157299), we confirmed the latency reversal properties of in vivo TGF-ß blockade, decreased viral reservoirs and stimulated immune responses. Eight SIV-infected macaques on suppressive ART were treated with 4 2-week cycles of galunisertib. ART was discontinued 3 weeks after the last dose, and macaques euthanized 6 weeks after ART-interruption(ATI). One macaque did not rebound, while the remaining rebounded between week 2 and 6 post-ATI. Galunisertib led to viral reactivation as indicated by plasma viral load and immunoPET/CT with the 64Cu-DOTA-F(ab')2-p7D3-probe. Half to 1 Log decrease in cell-associated (CA-)SIV DNA was detected in lymph nodes, gut and PBMC, while intact pro-virus in PBMC decreased by 3-fold. No systemic increase in inflammatory cytokines was observed. High-dimensions cytometry, bulk and single-cell RNAseq revealed a shift toward an effector phenotype in T and NK cells. In summary, we demonstrated that galunisertib, a clinical stage TGFß inhibitor, reverses SIV latency and decreases SIV reservoirs by driving T cells toward an effector phenotype, enhancing immune responses in vivo in absence of toxicity.

The status of specialist neurosurgical training in Nigeria: A survey of practitioners, trainers, and trainees.

OBJECTIVE: Despite the well-known neurosurgical workforce deficit in Sub-Saharan Africa, there remains a low number of neurosurgical training programs in Nigeria. This study sought to re-assess the current status of specialist neurosurgical training in the country. METHODS: An electronic survey was distributed to all consultant neurosurgeons and neurosurgery residents in Nigeria. Demographic information and questions relating to the content, process, strengths, and challenges of neurosurgical training were explored as part of a broader survey assessing neurosurgical capacity. Descriptive statistics were used for analysis. RESULTS: Respondents identified 15 neurosurgical training centers in Nigeria. All 15 are accredited by the West African College of Surgeons (WACS), and 6 by the National Postgraduate Medical College of Nigeria (NPMCN). The average duration of core neurosurgical training was 5 years. Some identified strengths of Nigerian neurosurgical training included learning opportunities provided to residents, recent growth in the neurosurgical training capacity, and satisfaction with training. Challenges included a continued low number of training programs compared to the population density, lack of subspecialty training programs, and inadequate training infrastructure. CONCLUSION: Despite the high number of neurosurgery training centers in Nigeria, compared to other West African countries, the programs are still limited in number and capacity. Although this study shows apparent trainee satisfaction with the training process and contents, multiple challenges exist. Efforts at improving training capacity should focus on continuing the development and expansion of current programs, commencing subspecialty training, driving health insurance to improve funding, and increasing available infrastructure for training.

Synchronous primary malignancies of papillary thyroid carcinoma and Hodgkin lymphoma: Interventions and outcome.

Thyroid carcinoma is uncommon. Papillary thyroid carcinoma (PTC) represents the majority of differentiated thyroid carcinoma and is a recognised complication of prior exposure to ionizing radiation. Even more uncommon is the synchronous occurrence of PTC with Hodgkin lymphoma (HL) as multiple primary malignancies. We report a 33-year-old mother of three who developed asymptomatic thyroid nodule for four years, and neck swelling for the recent ten months. She denied constitutional symptoms or B symptoms, and thyroid profiles were normal. Initially, metastatic thyroid cancer was suspected based on ultrasound scan findings of enlarged left thyroid gland and enlarged supraclavicular lymph nodes (LN). However, fine needle aspiration examinations of the thyroid nodule were inconclusive, and the supraclavicular LN was suspicious of HL. Computerised tomography scan detected a large mass at the thyroid glands and lymphadenopathies in the mediastinal, hilar, subcarinal and axilla with dimensions up to 6 cm. Left hemi-thyroidectomy with left supraclavicular LN biopsy revealed PTC in the left thyroid lobe measuring 38 x 25 x 18 mm, and the left supraclavicular LN was not definitive of HL. Completion thyroidectomy on the right side, bilateral central neck dissection and excision biopsy of the right supraclavicular LN revealed the presence of HL in the right supraclavicular LN, and both HL and metastatic PTC in right central LN. After multidisciplinary discussions, the patient received chemotherapy at four weeks postoperatively and achieved complete remission. This report highlights the importance of patient-centered approach and multidisciplinary consensus within lack of established guidelines, given rarity of the case.

Efficacy and complications of hyaluronic acid and polylactic acid for penile augmentation: a systematic review and meta-analysis.

Background: Penile size is considered a symbol of manhood and is a subjective problem for men, especially those with small penis syndrome. Penile augmentation was introduced to correct penile size problems from a medical, psychological, or esthetic point of view. Hyaluronic acid (HA) and polylactic acid (PLA) are two types of augmentation agents that are popularly used today. However, no systematic studies and meta-analyses have compared these two modalities as penile augmentation agents. This study aimed to analyze the efficacy and safety of penile filler injections with HA compared to PLA. Methods: This study was based on the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Articles examining the differences in efficacy and adverse events of the administration of HA and PLA in patients undergoing penile augmentation were systematically reviewed from the PubMed, Proquest, Web of Science, and Scopus databases. An odds ratio with a 95% CI was applied to measure the study outcome. The analysis was performed with RevMan 5.4 software. The risk of bias for each study was evaluated using the Risk of Bias v2 instrument from Cochrane. This research protocol is registered in the International Prospective Register of Systematic Reviews (PROSPERO) registry. Result: Four articles consisting of 283 research subjects were included in this study. The meta-analysis for penile girth enhancement after penile augmentation found significant results in the HA group compared to the PLA group (P=0.01). There was no difference in the level of satisfaction with penile appearance 4 weeks after penile augmentation in the HA group compared to the PLA group (P=0.79). HA was significantly superior in sexual satisfaction 12 weeks postpenile augmentation (P=0.0004). There was no difference in the incidence of pain after penile augmentation in the HA group compared to the PLA group (P=0.33). In the postaugmentation penile inflammation, there was no difference (P=0.98) in the HA group compared to the PLA group. Conclusion: There are differences in the efficacy of penile augmentation with the superiority of HA in increasing penile diameter and postaugmentation sexual satisfaction compared to PLA. There was no difference in the incidence of complications between using HA and PLA.

Increased serum activin A level in congenital heart disease-associated pulmonary artery hypertension: A comparative study from the COHARD-PH registry.

Activin A, a member of TGF-ß superfamily, has been implicated in the pathogenesis of pulmonary artery hypertension (PAH). PAH due to congenital heart disease (CHD-PAH) is a major problem in developing countries. Activin A may have a role in PAH development and progression among uncorrected CHD. In this comparative study, serum activin A level was significantly increased in subjects with uncorrected CHD without the presence of PH and were more significantly risen in CHD-PAH, as compared to control. The utilization of serum activin A measurement seems promising to identify uncorrected CHD patients with PAH development and progression.

The comparison of anastomosis strength and leakage between double-layer full-thickness and single-layer extramucosal intestine anastomosis.

Various intestine anastomosis techniques have been studied and used, but which is best is still debated. In our center, double-layer full-thickness intestine anastomosis was still considered as standard. However, a single-layer extramucosal intestine anastomosis has shown favorable results. This study created an anastomotic model to compare the anastomosis strength and leakage between double-layer full-thickness and single-layer extramucosal intestine anastomosis. Methods: This experimental study was performed in 20 randomized healthy male pigs, to be included either in Group A (Single-layer extramucosal intestine anastomosis) or Group B (Double-layer full-thickness intestine anastomosis). Enterotomy followed by an end-to-end anastomosis suture was performed in the jejunum. Fourteen days after the operation, any anastomosis leakage and its location was documented. The anastomosis strength was evaluated using manometry. Data were compared between groups using the Mann-Whitney U and Fischer Exact test, considering a significance level of P<0.05. Results: The overall mean intraluminal anastomotic bursting pressure was 4,257±1,185. Group A had a higher intraluminal anastomotic bursting pressure but was not statistically significant compared to group B (4.726±0.952 vs. 3.787±1.252 kilopascals, P=0.063). One leakage (5%, antimesenteric area) occurred in Group A and three leakages (15%, antimesenteric and mesenteric area) occurred in Group B. However, statistical analysis with Fischer exact showed no significant difference of leakage rate between those groups (P=0.291). Conclusions: The anastomosis strength and leakage did not differ significantly between the single-layer extramucosal intestine anastomosis group and the double-layer full-thickness anastomosis group. However, the location of leakage was most common in the antimesenteric area in the double-layer full-thickness anastomosis group.
