Incidence and outcome of isolated distal deep vein thrombosis in kidney transplant recipients.

Ann Surg Treat Res 2020 Jun 28;98(6):324-331. Epub 2020 May 28.

Division of Vascular and Transplant Surgery, Department of Surgery, Uijeongbu St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Uijeongbu, Korea.

Purpose: Isolated distal deep vein thrombosis (IDDVT) is a localized lesion; nonetheless, the risk of proximal vein propagation makes it difficult to decide on the treatment protocol-that is, whether immediate anticoagulation after diagnosis or surveillance via serial imaging should be employed. This study aimed to investigate the appropriate treatment protocol for IDDVT in kidney transplant recipient (KTR).

Methods: Surveillance for venous thromboembolism (VTE) was performed using duplex ultrasonography (DUS) before transplant surgery and at 1 week, 2 weeks, 1 month, 3 months, 6 months, and 1 year after transplant surgery. Read More

Is platelet-rich plasma improves the anastomotic healing in hyperthermic intraperitoneal chemotherapy with oxaliplatin: an experimental rat study.

Ann Surg Treat Res 2020 Feb 31;98(2):89-95. Epub 2020 Jan 31.

Department of Pathology, University of Healthy Sciences, Samsun Research and Training Hospital, Samsun, Turkey.

Purpose: Hyperthermic intraperitoneal chemotherapy (HIPEC) is a novel treatment option for peritoneal surface malignancies. Due to cytotoxic effects of chemotherapeutic agents, anastomosis healing can be impaired and lead to leakage rates higher than conventional intestinal surgery. In this experimental study, we aimed to investigate the effects of platelet-rich plasma (PRP) on colonic anastomosis in rats that received HIPEC with oxaliplatin. Read More

What are the most important predictive factors for clinically relevant posthepatectomy liver failure after right hepatectomy for hepatocellular carcinoma?

Ann Surg Treat Res 2020 Feb 31;98(2):62-71. Epub 2020 Jan 31.

Department of Surgery, Yonsei University College of Medicine, Seoul, Korea.

Purpose: The risk of posthepatectomy liver failure (PHLF) after right hepatectomy remains substantial. Additional parameters such as computed tomography volumetry, liver stiffness measurement by FibroScan, indocyanine green retention rate at 15 minutes, and platelet count used to properly assess future liver remnant volume quality and quantity are of the utmost importance. Thus, we compared the usefulness of these modalities for predicting PHLF among patients with hepatocellular carcinoma after right hepatectomy. Read More

Nipple-sparing mastectomy through periareolar incision with immediate reconstruction.

Ann Surg Treat Res 2020 Feb 31;98(2):57-61. Epub 2020 Jan 31.

Department of Surgery, College of Medicine, Ewha Womans University, Seoul, Korea.

Purpose: Nipple-sparing mastectomy (NSM) has become increasingly popular due to improved cosmesis without compromising oncologic safety. Radial and inframammary incisions are usually used to achieve NSM, with periareolar incisions usually being avoided because of the risk to nipple-areola complex viability. In an attempt to maximize esthetic effects, we performed NSM through periareolar incision with immediate reconstruction. Read More

Validation of an automated adenoma detection rate calculating system for quality improvement of colonoscopy.

Ann Surg Treat Res 2019 Dec 2;97(6):319-325. Epub 2019 Dec 2.

Center for Colorectal Cancer, Research Institute and Hospital, National Cancer Center, Goyang, Korea.

Purpose: This study aimed to validate an automated calculating system developed for determining the adenoma detection rate (ADR).

Methods: To calculate the automated ADR, the data linking processes were as follows: (1) matching the selected colonoscopy results with the pathological results, (2) matching the polyp number from colonoscopy with that from pathology and confirming the histopathological results of each colonic polyp, and (3) confirming the histopathological results, especially the adenoma status of each colonic polyp. To verify the accuracy of the automated ADR calculating system, we manually calculated the ADR for 3 months through medical record review. Read More
