Antimicrobial resistance profile in Salmonella enterica serovar Choleraesuis isolates from diseased pigs in Taiwan.

This study investigated antimicrobial resistance in Salmonella enterica serovar Choleraesuis (S. Choleraesuis) isolates from diseased pigs in Taiwan (2015-2020). Among 272 isolates, florfenicol (96.7%), enrofloxacin (96.3%), doxycycline (91.2%), gentamicin (84.6%), and tiamulin (80.5%) exhibited high resistance. 99.3% of the isolates were resistant to at least one antibiotic, and 97.8% of the isolates were multidrug resistant. This study illustrated that S. Choleraesuis isolates exhibited high resistance to antimicrobials currently used in the Taiwanese swine industry.

Survival outcomes of the combination of extrafascial extrahepatic and extrafascial intrahepatic pedicle approaches in hepatectomy for hepatocellular carcinoma.

Introduction: This study was conducted to evaluate the results of hepatectomy for hepatocellular carcinoma (HCC) by the combination of extrafascial extrahepatic (Takasaki method) and extrafascial intrahepatic pedicle approaches (Ton That Tung method). Material and methods: A longitudinal follow-up study was conducted on 83 patients undergoing hepatectomy for HCC using the combination of extrafascial extrahepatic (Takasaki method) and extrafascial intrahepatic pedicle approaches at Nghe An Provincial Hospital from April 2017 to July 2021. Survival analysis was applied. Results: The cumulative overall survival (OS) rates after 1, 2, 3 and 4 years were 88.4%, 76.3%, 69.5% and 56.9%, respectively. The mean OS time was 40.68 ±2.17 months. The 1-, 2-, 3- and 4-year disease-free survival (DFS) rates were 67.1%, 56%, 53.1% and 50%, respectively. The mean DFS time was 32.58 ±2.56 months. Surgical margin > 1 cm was an independent predictor of both overall and disease-free survival (HR = 5.194, 95% CI = 1.467-18,385, p = 0.011 for OS; HR = 2.822, 95% CI = 1.231-6.468, p = 0.014 for DFS). Conclusions: Hepatectomy for HCC by a combination of extrafascial extrahepatic (Takasaki method) and extrafascial intrahepatic pedicle approaches (Ton That Tung method) is effective and safe, and side effects and complications can be controlled. Patient selection is a key issue and plays a very important role in the outcome of treatment.

Hepatectomy using a combination of extrafascial extrahepatic (Takasaki approach) and extrafascial intrahepatic pedicle approaches (Ton That Tung approach).

Selective pedicle control and anatomical liver resection are considered standard techniques in hepatectomy for hepatocellular carcinoma. In 1963, Ton That Tung made significant improvements in hepatectomy techniques with the principle of locating and ligation of Glissonean pedicle in the liver parenchyma based on precise knowledge of vascular and biliary anatomy (Tung TT, Quang ND. A new technique for operating on the liver. Lancet 1963;281:192-3). In 1986, the extrafascial Glissonean dissection was first introduced by Takasaki in 1986. This is a simple and safe technique that helps to identify the exact borders between liver sections for anatomic liver resection (Takasaki K. Glissonean pedicle transection method for hepatic resection: a new concept of liver segmentation. J Hepatobiliary Pancreat Surg 1998;5:286-91). The combination of two techniques helps minimize complications, reduce ischemic time of future liver remnant, intraoperative blood loss and avoid migration of cancer cells into other segments.

Gallbladder volvulus and hernia through the foramen of Winslow: a case report.

Gallbladder hernia through the foramen of Winslow is an uncommon condition and gallbladder hernia combined with volvulus is even rarer. A 70-year-old patient was hospitalized with the clinical signs of pain in the right hypochondriac region associated with fever. The computed tomography scan images showed some signs of gallbladder herniation through the foramen of Winslow. We decided to remove the gallbladder and found the gallbladder infundibulum twisted and necrotic. This was the first case of a male patient who suffered from gallbladder herniation with volvulus after three cases of female patients reported in the literature.
