This case report presents 2 patients with gastroesophageal junction cancer who both underwent totally minimally invasive esophagectomy with colon interposition. Patients 1 and 2, who were 43-year-old and 78-year-old men, respectively, had distinct clinical presentations and medical histories. Patient 1 underwent minimally invasive robotic esophagectomy with a laparoscopic total gastrectomy, colonic conduit preparation, and intrathoracic esophago-colono-jejunostomy. Patient 2 underwent completely robotic total gastrectomy, colon conduit preparation, and intrathoracic esophago-colono-jejunostomy. The primary challenge in colon interposition is assessing colon vascularity and ensuring an adequate conduit length, which is critical for successful anastomosis. In both cases, we used indocyanine green fluorescence angiography to evaluate vascularity. Determining the appropriate conduit is challenging; therefore, it is crucial to ensure a slightly longer conduit during reconstruction. Because totally minimally invasive colon interposition can reduce postoperative pain and enhance recovery, this surgical technique is feasible and beneficial.

Kudoa septempunctata, a myxozoan parasite, usually presents without any signs and primarily infects adult fish. The invasive diagnostic methods, such as tissue biopsy, can identify pathogens, but cause economic losses because they require killing the fish. In this study, we conducted a monitoring of four fish farms located on Jeju Island, to investigate the potential for non-invasive diagnosis of K. septempunctata using hyperspectral cameras. It provides spectral information from R000_B000_G000 to R255_B255_G255 for a total of 3,282 olive flounder (Paralichthys olivaceus). Each object is imaged with 2,000 data points, allowing comprehensive spectral analysis by comparing images obtained from negative control objects to positive control objects. Noticeable differences were observed in the brightness or pallor of the positive control images. This suggests the potential utility of hyperspectral imaging as a non-invasive diagnostic tool for detecting K. septempunctata infections in fish populations.

Recently, many advanced technologies in electronics, mechanics, material and computer science have been applied to medictine and they have changed the method of diagnosis and treatment to more quantitative way than before. Now day, with the aid of this technology, the device for the minimal invasive diagnosis and treatment is being developed for the convenience and safety of patients. this paper introduces application of senso and MEMS(Micro Electro Mechnical System) in medicine and biotechnology, which are essential factor for the realization of minimal invasive diagnosis and treatment.

Tunicates were collected from three harbors (Gampo, Bangeojin, Daebyeon) in Gyeongsangnam-do and one harbor (Seogwipo) in Jejudo Island during the period from August 2008 to January 2011 and were identified on the basis of their morphological characteristics. Among them, colonial tunicate Clavelina lepadiformis (Muller, 1776) belonging to the family Clavelinidae was found to be an invasive alien species introduced from the North Atlantic, and this is the first record of its occurrence in Korea.

With the marked decrease in operative mortality in simple heart diseases there have been several reports on the minimally invasive and cosmetic techniques including submammary incision right parasternal approach right anterolateral thoracotomy partial sternotomy and subxiphoid approach. We report here subxiphoid approach without sternotomy for the repair of atrial septal defect as the procedure that has less invasive technique and more cosmetic effect.

Pulmonary aspergillosis is the most common disease of fungal infection and has lower infectivity. Pulmonary asergillosis is classified by aspergilloma, bronchopulmonary aspergillosis, necrotic and invasive aspergillosis. Invasive aspergillosis is found in immune compromised host, immunosuppressive treatment after organ transplantation, anticancerous chemotherapy, blood abnormality, AIDS patients etc. We reported a case of invasive aspergillosis in an immunocompetent host, with review of literatures.

Chronic non-specific low back pain (CLBP) is one of the major health problems casting substantial amount of economic expenses and negative impact on quality of life onto an individual as well as society. On contrary to public familiarity, the ways of management of CLBP are diverse and there is yet no general consensus about which approach is better than others or to whom the specific management should be applied. Some hold the negative point of view on the efficacy of the invasive maneuver such as epidural injection because there is no controlled clinical trial (RCT) yielding better long term outcome of those invasive managements over conservative ones. But the experts of interventional or surgical treatment stress the methodological difficulty in performing RCT and assert that those invasive treatments can bring the prompt and complete resolution of low back pain and restoration of function in appropriately selected cases. These seemingly opposite views on the invasive management on CLBP are rather complimentary each other than to be contradictory.

We experenced 18 patients with surgically treated thymoma from January 1986 to December 1993. There were 13 male and 5 female ranged from 23 to 69 years of age. Among them Myasthenia gravis was present in 8 patients (44%) The predominant cell type was lymphocytic(11 patients), followed by epithelial (3) and mixed (4), and had no value in predicting prognosis. Treatment consisted of complete resection in 15 patients, partial resection in 2 patients and 1 patient was performed biopsy. Only, and then adjuvant radiation therapy was done in 7 patients and 3 patients needed adjuvant chemotherapy. Invasion of the adjacent tissue in thymoma was the most improtant prognostic value. There were 6 non-invasive tumors and 12 invasive tumors. Two patients with invasive thymomas resulted in death and one of 6 patients with non-invasive thymomas died during follow up ranged from 25 day to 60 months. The causes of death were myasthenic crisis in 1 patient, C. N. S. problem in 1 patient and pulmonary & mediastinal metastasis in 1 patient.

Objective : Lumbar foraminal stenosis is an important etiology of lumbar radicular symptomatology and frequent causes of remained symptoms after decompressive surgery. This study was conducted to determine the precise clinical and radiologic diagnosis of lumbar foraminal stenosis, and to demonstrate thorough treatment by decompressive surgery using a minimally invasive technique. Methods : Seven patients with established unilateral lumbar foraminal stenosis according to clinical and radiologic diagnosis were retrospectively studied. All patients underwent combined interlaminar and paraisthmic procedure with partial facetectomy. The outcome of surgery was evaluated and classified into excellent, good, fair and poor. Results : The results were excellent in four patients, good in two, and fair in one during the follow-up. There were no surgery-related complications. Conclusion : Minimally invasive combined interlaminar and paraisthmic approach provides good outcome in carefully selected patients with symptomatic lumbar foraminal stenosis.

We performed taxonomic reviews and habitat circumstances survey for 41 un-introduced environmentally harmful plants (as designated by the Ministry of Environment, Korea in 2016). For this purpose, we investigated plant specimens from several herbaria and performed a field survey in the southeastern region of the United States. Base on the result, we presented the most comprehensive results of weed risk evaluation and taxonomic description up to now as well as classification keys for 11 species to apply the regulation management of putative invasive alien species - Centaurea maculosa Lam., Centaurea diffusa Lam., Mikania micrantha Kunth. (Asteraceae), Cenchrus echinatus L., Neyraudia reynaudiana (Kunth) Keng ex Hitchcock, Brachiaria mutica (Forsskål) Stapf, Vulpia bromoides (L.) Gray, Lolium persicum Boissier & Hohennacker, Setaria palmifolia (J. Konig) Stapf (Poaceae), Prosopis glandulosa Torr. (Fabaceae), Fallopia baldschuanica (Regel) Hobub. (Polygonaceae).
