Article Abstract
Necropsobacter rosorum is a gram-negative facultative anaerobe, which was reclassified from the family Pasteurellaceae in 2011. It has been detected in the gastrointestinal and respiratory tracts of mammals; however, reports of infection in humans are scarce. We report a case of an abdominal abscess in which N. rosorum was detected; it was successfully treated with drainage and antimicrobial therapy. Routine laboratory testing such as matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and an identification system using biochemical phenotypes could not identify N. rosorum. Instead, it was misidentified as other Pasteurellaceae species, including Aggregatibacter spp. or Pasteurella spp. Sequencing of 16S rRNA was required to identify N. rosorum. We suggest the application of simple methods, such as indole production, oxidase, and catalase tests, to differentiate N. rosorum from genetically similar species.

Obesity affects about 39% of the global population, and bariatric surgery is a leading treatment option. As the number of primary bariatric procedures increases, so does the demand for revisional bariatric surgeries (RBSs), which are often more complex and associated with increased risks of complications. This case report details an unusual complication of RBS that surgeons should be aware of.

A 63-year-old woman underwent living-donor kidney transplantation three years earlier for end-stage renal disease due to diabetic nephropathy, with her younger sister as the donor. She was prescribed calcium polystyrene sulfonate for the management of hyperkalemia, which had been discontinued two years earlier. At this time, she developed recurrent abdominal and urinary symptoms, which were managed empirically with antibiotics.

Background: We investigated whether the standardized "can-opener method" surgical technique is an adequate surgical procedure for hemispheric hepatectomy in segments 7 and 8.
Methods: Forty-two patients who underwent laparoscopic hemispheric liver resection for segments 7 and 8 using our standardized surgical technique were enrolled. To examine the effect of this standardized surgical procedure on short-term outcomes, patients were classified into two groups based on the timing of the standardization of their procedures (Group A, the first half of the cases, and Group B, the second half of the cases).
