Replacing the retrohepatic inferior vena cava (IVC) following concurrent resection of the IVC and tumor-involved liver is an emerging surgical technique in living donor liver transplantation (LDLT), particularly for managing hepatocellular carcinomas near the IVC. This approach makes the extent of hepatectomy in LDLT comparable to that of deceased donor liver transplantation. We report a pediatric LDLT case involving IVC and portal vein (PV) replacement with an iliac vein homograft to treat advanced hepatoblastomas. The patient was a 24-month-old girl weighing 9.1 kg, presenting with large, multiple hepatoblastomas infiltrating the retrohepatic IVC and PV. After a 2-week waiting period, a cold-stored iliac vein graft was obtained, and the transplantation was performed using a left lateral section graft from her father.A 4-cm iliac vein homograft was anastomosed between the suprahepatic and suprarenal IVC stumps. The liver graft was implanted following standard procedures, with the PV reconstructed via a telescope-shaped anastomosis using the vein graft interposition. The patient experienced an uncomplicated recovery and is currently receiving scheduled adjuvant chemotherapy. In conclusion, IVC and PV replacement with vein homografts represents a feasible and effective surgical strategy for pediatric LDLT patients with advanced liver malignancies involving vascular invasion.

In children with biliary atresia, recurrent episodes of cholangitis often lead to portal vein (PV) phlebosclerosis. We report a case of pediatric living donor liver transplantation (LDLT) for biliary atresia with PV occlusion and a large splenorenal shunt. A 3-year-5-month-old girl was diagnosed with syndromic biliary atresia and polysplenia. Because the patient’s condition progressively deteriorated with worsening jaundice, we opted to perform LDLT using a left lateral section graft from her father. The recipient’s native PV was severely atrophic and completely occluded, and the collateral veins around the hepatoduodenal ligament were too small to serve as a viable source of portal inflow.Consequently, renoportal anastomosis (RPA) was selected as an alternative approach.Iliac vein interposition was performed to provide a new portal inflow source, and anatomy-compliant PV reconstruction was performed. The patient recovered from transplant surgery, but PV conduit stenosis occurred with the development of ascites 2 months posttransplant. This RPA-related vascular complication was resolved through percutaneous balloon angioplasty of the PV conduit. The patient has been doing well for 6 months posttransplantation. This case demonstrates that RPA can represent a viable reconstructive option for PV inflow in liver transplantation for pediatric patients with phlebosclerotic PV and prominent splenorenal shunt.

Purpose: To report a case of recurrent hypotony and exudative choroidal detachment in a patient with pseudoexfoliation glaucoma following the use of a topical preservative-free prostaglandin–timolol fixed combination eye drop.Case summary: A 74-year-old diabetic patient with a history of trabeculectomy for pseudoexfoliation glaucoma presented with conjunctival hyperemia, ocular pain, and blurred vision 3 months after using a preservative free prostaglandin-timolol fixed combination. Intraocular pressure (IOP) was markedly reduced to 6 mmHg and fundus examination revealed severe exudative choroidal detachment involving three quadrants. Treatment with oral and topical corticosteroids, cycloplegics, and non-steroidal anti-inflammatory drugs normalized his IOP to 15 mmHg and resolved the detachment within 3 weeks. Two weeks later, the patient inadvertently reused the same medication mistaking it for artificial tears. Symptoms recurred the following day with his IOP dropping to 2 mmHg and choroidal detachment affecting all four quadrants. Re-treatment led to full recovery within 3 weeks. Conclusions Choroidal detachment following use of combination therapy with a prostaglandin analog and an aqueous suppressant is a rare complication. Patients with pseudoexfoliation syndrome and diabetes may be particularly susceptible. Vigilant monitoring of IOP and fundus status is recommended when prescribing these agents to individuals with multiple risk factors.

Replacement of the retrohepatic inferior vena cava (IVC) after concurrent resection of IVC and tumor-bearing liver is regarded as a feasible living donor liver transplantation (LDLT) technique to cope with tumors around the IVC. This method can make the resection extent of LDLT comparable to that of deceased-donor liver transplantation. We present one pediatric LDLT case with IVC replacement using an enlarged iliac vein conduit to treat advanced hepatoblastoma. The patient was a 33-monthold and 12 kg-weighing girl suffering from large multiple hepatoblastomas invading the retrohepatic IVC. At 2-month waiting after deciding LDLT, we obtained a coldstored iliac vein graft and LDLT was performed with the father’s left lateral section graft. A 1.3 cm-wide and 10 cm-long iliac vein was transformed to be a 2 cm-wide and 5 cm-long vein graft through a double-barrel unification venoplasty. The left lateral section graft was implanted along the standard procedure of LDLT. The patient recovered uneventfully and is undergoing scheduled adjuvant chemotherapy. IVC replacement with vein homograft is a feasible option for LDLT in pediatric patients with advanced liver malignancy.

Background: Healthcare-associated infections impose a significant burden on antibiotic usage, healthcare expenditures, and morbidity. Therefore, it is crucial to revise policies to minimize such losses. This nationwide survey aimed to evaluate infection prevention and control (IPC) components in healthcare facilities and encourage improvements in acute care hospitals with inadequate infection prevention settings. This study aims to enhance the infection control capabilities of healthcare facilities. Methods: From December 27, 2021, to May 13, 2022, we conducted a survey of 1,767 acute care hospitals in the Republic of Korea. A survey was conducted to evaluate the infection control components in 1,767 acute care hospitals. Infection control officers provided direct responses to a systematically developed questionnaire. Subsequently, 10% of the respondents were randomly selected for the site investigation. Results: Overall, 1,197 (67.7%) hospitals responded to the online survey. On-site investigations were conducted at 125 hospitals. Hospitals with ≥ 150 beds are advised to have an IPC team under Article 3 of the Medical Service Act; however, only 87.0% (598/687) of hospitals with ≥ 100 beds had one. Conversely, 22.7% (116/510) of hospitals with < 100 beds had an IPC team. Regulations for hand hygiene, waste management, healthcare worker protection and safety, environmental cleaning, standard precautions, and prevention of the transmission of multidrug-resistant pathogens were present in 84.2%, 80.1%, 77.4%, 76.2%, 75.8%, and 63.5% of the hospitals, respectively. Hospitals with < 100 beds had low availability of all categories of standard operating procedures. Conclusion This study is the first national survey of acute care hospitals in the Republic of Korea. The data presented in the current study will improve the understanding of IPC status and will help establish a survey system. Our survey provides a basis for improving policies related to IPC in healthcare facilities.

Purpose: We present a case of goniosynechiolysis in the treatment of chronic angle-closure glaucoma with persistent peripheral anterior synechia (PAS) after extracapsular cataract extraction (ECCE) for phacomorphic glaucoma that remained uncontrolled using topical glaucoma medications.Case summary: A 59-year-old woman presented with right eye pain and visual loss that started 3 days ago. Examination revealed an intraocular pressure (IOP) of 46 mmHg, a narrow central anterior chamber, and peripheral iridocorneal touch, indicative of phacomorphic glaucoma. Although ECCE was performed, PAS was not adequately resolved. Initially, visual acuity, IOP, and visual field were controlled with a single topical glaucoma medication. However, progressive retinal nerve fiber layer thinning and uncontrolled IOP, despite maximal medical therapy. Therefore, goniosynechiolysis was performed at 24 months after ECCE. The procedure reduced IOP from 25 mmHg to 13 mmHg without complications, such as hyphema, cyclodialysis, and fibrin formation. Conclusions Goniosynechiolysis can be a safe and effective intervention for chronic angle-closure glaucoma with persistent PAS and elevated IOP.
