Preoperative neutrophil-lymphocyte ratio and CEA is associated with poor prognosis in patients with synchronous colorectal cancer liver metastasis.

Ann Surg Treat Res 2019 Apr 28;96(4):191-200. Epub 2019 Mar 28.

Department of Surgery, Soonchunhyang University Cheonan Hospital, Cheonan, Korea.

Routine low-dose calcium supplementation after thyroidectomy does not reduce the rate of symptomatic hypocalcemia: a prospective randomized trial.

Ann Surg Treat Res 2019 Apr 28;96(4):177-184. Epub 2019 Mar 28.

Department of Surgery, Ewha Womans University Medical Center, Seoul, Korea.

Genetic features associated with F-FDG uptake in intrahepatic cholangiocarcinoma.

Ann Surg Treat Res 2019 Apr 28;96(4):153-161. Epub 2019 Mar 28.

Department of Nuclear Medicine, Keimyung University Dongsan Medical Center, Daegu, Korea.

Purpose: In intrahepatic cholangiocarcinoma (iCCA), genetic characteristics on F-fluorodeoxyglucose (F-FDG)-PET scans are not yet clarified. If specific genetic characteristics were found to be related to FDG uptake in iCCA, we can predict molecular features based on the FDG uptake patterns and to distinguish different types of treatments. In this purpose, we analyzed RNA sequencing in iCCA patients to evaluate gene expression signatures associated with FDG uptake patterns. Read More

Different prognostic values of individual hematologic parameters in papillary thyroid cancer due to age-related changes in immunity.

Ann Surg Treat Res 2019 Feb 30;96(2):70-77. Epub 2018 Jan 30.

Department of Surgery, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul, Korea.

Purpose: Several studies have reported the plausible association of neutrophil-to-lymphocyte ratio (NLR) with the prognosis of papillary thyroid cancer (PTC), but the results are inconsistent. In PTC, chronic inflammation is closely related to tumor progression, and the age of the patient has a great influence on prognosis. Therefore, considering the changes in the immune system with aging, we classified the patients according to age and assessed the prognostic value of individual hematologic parameters. Read More

Single-incision laparoscopic ileostomy is a safe and feasible method of fecal diversion for anastomotic leakage following laparoscopic low anterior resection.

Ann Surg Treat Res 2018 Dec 26;95(6):319-323. Epub 2018 Nov 26.

Department of Surgery, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Korea.

Effects of acute normovolemic hemodilution on healing of gastric anastomosis in rats.

Ann Surg Treat Res 2018 Dec 26;95(6):312-318. Epub 2018 Nov 26.

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

Purpose: Acute normovolemic hemodilution (ANH) is an autologous transfusion method, using blood collected during surgery, to reduce the need for allogeneic blood transfusion. ANH is controversial because it may lead to various complications. Among the possible complications, anastomotic leakage is one that would have a significant effect on the operation outcome.

Validation of the OncoHepa test, a multigene expression profile test, and the tumor marker-volume score to predict postresection outcome in small solitary hepatocellular carcinomas.

Ann Surg Treat Res 2018 Dec 26;95(6):303-311. Epub 2018 Nov 26.

Department of Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.

Preliminary study on application of augmented reality visualization in robotic thyroid surgery.

Ann Surg Treat Res 2018 Dec 26;95(6):297-302. Epub 2018 Nov 26.

Department of Biomedical Engineering, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea.

Purpose: Increased robotic surgery is attended by increased reports of complications, largely due to limited operative view and lack of tactile sense. These kinds of obstacles, which seldom occur in open surgery, are challenging for beginner surgeons. To enhance robotic surgery safety, we created an augmented reality (AR) model of the organs around the thyroid glands, and tested the AR model applicability in robotic thyroidectomy. Read More

The long-term prognostic impact of sentinel lymph node biopsy in patients with primary cutaneous melanoma: a prospective study with 10-year follow-up.

Ann Surg Treat Res 2018 Nov 25;95(5):286-296. Epub 2018 Oct 25.

Department of Surgery and Department of Morphology, Surgery and Experimental Medicine, S. Anna University Hospital and University of Ferrara, Ferrara, Italy.

Purpose: Sentinel lymph node (SLN) biopsy (SLNB) is widely accepted for staging of melanoma patients. It has been shown that clinico-pathological features such as Breslow thickness, ulceration, age, and sex are better predictors of relapse and survival than SLN status alone. The aims of this study were to evaluate the long-term (10-year) prognostic impact of SLNB and to determine predictive factors associated with SLN metastasis, relapse, and melanoma specific mortality (MSM).

Usefulness of dynamic risk stratification in pediatric patients with differentiated thyroid carcinoma.

Ann Surg Treat Res 2018 Oct 28;95(4):222-229. Epub 2018 Sep 28.

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

Purpose: Recently, the American Thyroid Association (ATA) dynamic risk stratification (DRS) has been verified to be more valuable than the static anatomical staging system for predicting prognosis in patients with differentiated thyroid carcinoma (DTC). The purpose of this retrospective study was to compare the clinical usefulness of DRS, which is based on the response to initial treatment, with that of ATA initial risk stratification in pediatric patients.

Methods: A total of 144 pediatric patients underwent thyroid operation from August 1982 to December 2013 at Yonsei University Hospital (Seoul, Korea). Read More

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

Purpose: The prognostic influence of 3-dimensional tumor volume (Tv) on breast cancer compared to conventional 1-dimensional tumor size (T) was investigated.

Methods: Analysis was performed on a cohort of 8,996 primary breast cancer patients who were initially diagnosed with TNM stage I-III. Tumor size was defined as the maximum tumor dimension, and Tv was calculated by the equation of (4π × r1 × r2 × r3)/3; r1, r2, and r3 were defined as half of the largest, intermediate, and shortest dimension of the tumor, respectively.

Focal change of the pancreatic texture using a direct injection mixture of N-butyl cyanoacrylate and lipiodol in the pig model: a strategy for preventing pancreatic leakage during pancreatic surgery.

Ann Surg Treat Res 2018 Oct 28;95(4):175-182. Epub 2018 Sep 28.

Department of Hepato-Biliary and Pancreas Surgery, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Korea.

Purpose: A soft texture of the pancreas is one of the most important predisposing factors for a pancreatic fistula. Thus, in a porcine model, we investigated a method to harden the pancreas locally by directly injecting an artificial material.

Methods: During the laparotomy, 51 samples from 17 pigs, including 13 survival models, were randomly divided into 3 groups and either received a direct injection into the pancreas of MHL (1:4 mixture of histoacryl [n-butyl cyanoacrylate] and lipiodol) (group E) or saline (group C) or only received a pinprick into the pancreas without injecting a substance (sham).
