Background/Aims: To investigate the potential value of the use of the fibrin glue-antibiotic mixture in the treatment of anal fistulae. Materials and Methods: This study included 69 patients with idiopathic nonspecific anal fistulae. Patients with IBD (inflammatory bowel disease), TBC, actinomycosis, and cancer were excluded from the study. The microbiological analysis of the discharge of the fistula was done routinely. If there was any doubt about vertical classification of the fistulous tract MR of anal canal was necessary. As regards the vertical disposition, 39 fistulae were classified as intersphincteric and 30 as transsphincteric, and as to the length of the fistulous tract, 24 fistulas had tracts ≤3.5 cm long, and 45 fistulas had tracts >3.5 cm long. All fistulae were first treated with the lavage of the fistulous tract with antibiotic solution until a sterile microbiological finding was obtained. This was followed by electrocoagulation of the fistulous tract with a special probe for the eradication of granulomatous tissue. Finally the fibrin glue-antibiotic mixture (Tisseel, Immuno Ltd., Vienna, Austria) was applied. Results: After a follow-up of 18–36 months (median 28) 18 patients (26%) had a recurrence; among these, intersphincteric fistula recurred in 9 patients (23%) and transsphincteric also in 9 (30%). Regarding the length of the fistulous tract, a fistula with a ≤3.5 cm long tract recurred in 13 patients (54%) and a fistula with a >3.5 cm long tract in 5 (11%). Conclusion: The analysis showed that the success of the treatment of anal fistulae with fibrin glue-antibiotic mixture was independent of the vertical disposition of the fistula, and was dependent on the length of the fistulous tract. Surgical treatment remains a golden standard for simple fistulae with a tract ≤3.5 cm. Anal fistulae with a longer tract usually present a more complex problem and are often more difficult to treat surgically, the use of the fibrin glue-antibiotic complex proved to be a feasible method for those cases. It is a safe, cheap, reproducible, pain-free procedure, which eliminates the possibility of anal incontinence and can be performed under local anesthesia.

Summary Background 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov , NCT03471494 . Findings Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

In patients with hepatocellular carcinoma (HCC) meeting the Milan criteria (MC), the benefit of locoregional therapies (LRTs) in the context of liver transplantation (LT) is still debated. Initial biases in the selection between treated and untreated patients have yielded conflicting reported results. The study aimed to identify, using a competing risk analysis, risk factors for HCC‐dependent LT failure, defined as pretransplant tumor‐related delisting or posttransplant recurrence. The study was registered at http://www.clinicaltrials.gov (identification number NCT03723304). In order to offset the initial limitations of the investigated population, an inverse probability of treatment weighting (IPTW) analysis was used: 1083 MC‐in patients (no LRT = 182; LRT = 901) were balanced using 8 variables: age, sex, Model for End‐Stage Liver Disease (MELD) value, hepatitis C virus status, hepatitis B virus status, largest lesion diameter, number of nodules, and alpha‐fetoprotein (AFP). All the covariates were available at the first referral. After the IPTW, a pseudo‐population of 2019 patients listed for LT was analyzed, comparing 2 homogeneous groups of untreated (n = 1077) and LRT‐treated (n = 942) patients. Tumor progression after LRT was the most important independent risk factor for HCC‐dependent failure (subhazard ratio [SHR], 5.62; P < 0.001). Other independent risk factors were major tumor diameter, AFP, MELD, patient age, male sex, and period of wait‐list registration. One single LRT was protective compared with no treatment (SHR, 0.51; P < 0.001). The positive effect was still observed when 2‐3 treatments were performed (SHR, 0.66; P = 0.02), but it was lost in the case of ≥4 LRTs (SHR, 0.80; P = 0.27). In conclusion, for MC‐in patients, up to 3 LRTs are beneficial for success in intention‐to‐treat LT patients, with a 49% to 34% reduction in failure risk compared with untreated patients. This benefit is lost if more LRTs are required. A poor response to LRT is associated with a higher risk for HCC‐dependent transplant failure.
