Objective. To explore the safety and efficacy of small incision combined with nephroscope surgery in the treatment of infectious pancreatic necrosis. Methods. A retrospective analysis of the clinical data of 37 patients with infectious pancreatic necrosis who underwent small incision combined with nephroscopy in the Department of Hepatobiliary Surgery of Hunan Provincial People’s Hospital from January 2018 to December 2019. Results. All 37 patients successfully completed small incision combined nephroscope surgery. The median time from the onset to the operation of all patients was 38 days (range: 29-80 days), and the hospital stay was 19 days (range: 3-95 days). The median number of drainage tubes placed during the operation was 4 (range: 2-8). According to the different surgical approaches, 13 cases were through the retroperitoneal approach, 11 cases were through the omental sac approach, 2 cases were through the intercostal approach, and 11 cases were combined approach. The operation time was 85.3 ± 31.6  min, and intraoperative bleeding was 63.1 ± 40.0  ml. The incidence of complications (Clavien-Dindo grade 3 and above) was 5.4%. Among them, 2 patients were admitted to the intensive care unit due to postoperative bleeding, 1 case was cured by conservative treatment, and 1 case was cured by interventional treatment. During the follow-up period, 2 patients developed colonic fistula at 2 weeks after operation, and 2 patients developed gastric fistula at 1 week and 3 weeks after operation; all were cured by conservative treatment. Conclusion. Small incision combined with nephroscope surgery is an effective treatment for patients with infectious pancreatic necrosis by removing necrotic tissue, unobstructed drainage, and reducing complications.

AbstractWe conducted a retrospective analysis of 497 patients who underwent tonsillectomy at Kamio Memorial Hospital from September 2015 to August 2018. A total of 35 cases (7.0%) developed postoperative bleeding and three cases (0.6%) needed a second operation under general anesthesia to stop the bleeding. Postoperative bleeding most frequently occurred between 24 hours and 6 days after the operation. The incidence of postoperative bleeding was significantly higher in males and in patients aged 20 to 39 years old. The operation time, body mass index, smoking habit, and history of hypertension were not identified as clinical risk factors for bleeding after tonsillectomy in this study.

ABSTRACT Reference strains of infectious pancreatic necrosis virus resembling the 10 recognized serotypes and local isolates of aquabirnaviruses isolated in northwestern Spain from reservoirs (mollusks) and from asymptomatic and carrier cultured fish were genotyped by restriction fragment length polymorphism (RFLP) and nucleic acid sequence analyses. The RFLP analysis yielded seven genogroups, each of which was clearly correlated with a serotype. Sequence analysis of the three open reading frames provided quite similar results in terms of genogrouping. Based on the results of this study and in order to unify the two types of assays, we propose placing aquabirnaviruses into six genogroups, four of which can be subdivided into two genotypes based on a two-step restriction analysis. The genotyping corresponds with serotyping as follows: genogroup I includes two genotypes corresponding to serotypes A9 (genotype I.1) and A1 (genotype I.2); genogroup II corresponds to serotype A3; genogroup III includes genotypes III.1 (serotype A2) and III.2 (serotype B1); genogroups IV and V include two genotypes, each corresponding to serotypes A5, A6, A7, and A8 (genotypes IV.1, IV.2, V.1, and V.2, respectively);and genogroup VI corresponds to serotype A4. As expected, most local isolates belonged to genotype III.1 and genogroup II. However, a few local isolates corresponded to the American types of genogroup I. Finally, based on the results of this study and due to its simplicity, the two-step restriction analysis assay is proposed as a method for typing new isolates of aquabirnaviruses, and the results correspond to the results of conventional serotyping.
