BACKGROUND AND PURPOSE: Laser induced prostatectomy(LIP) has recently been considered as safe alternative to conventional transurethral resection of the prostate(TURP) in the surgical treatment of BPH. However, the value of LIP remains incompletely defined. We herein have performed a prospective study to compare TURP and LIP in treatment efficacy, safety and costs to define the value of LIP. MATERIALS AND METHODS: 113 patients with BPH who were candidates of TURP were randomized to undergo TURP or LIP and were adequately followed up for more than 1 year. There were no significant differences in preoperative clinical characteristics between 55 patients who underwent TURP and 58 patients who underwent LIP. For the LIP procedure, Nd:YAG was used in 42 patients and diode laser in 16 patients, respectively. 37 patients were treated by contact LIP only, and 21 with hybrid procedures of contact LIP and noncontact LIP using side firing laser fiber or interstitial laser fiber. Seven patients underwent LIP under local anesthesia at the outpatient department. RESULTS: International prostate symptom score(IPSS) and peak urinary flow rate(Qmax) were significantly improved at 3 months, 6 months, and 1 year after LIP as well as after TURP. There were no significant difference between TURP group(85.4%) and LIP group(87.9%) in treatment success rate as defined by improvement of IPSS and Qmax as well as patient's content for the surgical outcome. Nine(16.4%) and two(3.6%) of the patients who underwent TURP and none of the patients who LIP underwent developed ignificant bleeding and electrolyte imbalance, respectively. There were no significant difference in postoperative incidence of retrograde ejaculation, infection and urethral stricture between the two groups. Compared to TURP, the LIP procedure required significantly shorter hospitalization(6.8 vs 4.5 days) and catheterization(4.1 vs 2.6 days, all p<0.0l). There was no significant difference in total treatment cost between the two groups. CONCLUSIONS: LIP may be comparable to TURP in terms of short term treatment efficacy and cost effectiveness. LIP may be better than TURP in terms of safety and shortened hospitalization and catheterization. Further studies are necessary on long-term outcomes of LIP."

In situ follicular lymphoma is a newly defined entity among the lymphoid neoplasms and is defined as architecturally normal-appearing lymph nodes and other lymphoid tissues that have one or more follicles that demonstrate bcl-2 overexpressing centrocytes and centroblasts, with or without a monomorphic cytologic appearance suggestive of follicular lymphoma. Here we present a case of in situ follicular lymphoma diagnosed during the follow-up after a complete response to the treatment of lymphocyte-rich classical Hodgkin's lymphoma. In our case, because only a few germinal centers contained bcl-2 overexpressing cells, we missed the diagnosis of in situ follicular lymphoma in the initial histological examination. We could establish the diagnosis only after performing bcl-2 immunostaining in the sequential biopsy. Therefore, we recommend that careful histological examination along with bcl-2 immunostaining is needed in patients with suspicious clinical findings.

PURPOSE: Additional gastrectomy is needed after endoscopic resection for early gastric cancer when pathology confirms any possibility of lymph node metastasis or margin involvement. No studies depicted the optimal type of surgery to apply in these patients. We compared the short-term and long-term outcomes of laparoscopic gastrectomy with those of open gastrectomy after endoscopic resection to identify the optimal type of surgery. MATERIALS AND METHODS: From 2003 to 2010, 110 consecutive patients who underwent gastrectomy with lymphadenectomy either by laparoscopic (n=74) or by open (n=36) for gastric cancer after endoscopic resection were retrospectively analyzed. Postoperative and oncological outcomes were compared according to types of surgical approach. RESULTS: Clinicopathological characteristics were comparable between the two groups. Laparoscopic group showed significantly shorter time to gas passing and soft diet and hospital day than open group while operation time and rate of postoperative complications were comparable between the two groups. All specimens had negative margins regardless of types of approach. Mean number of retrieved lymph nodes did not differ significantly between the two groups. During the median follow-up of 47 months, there were no statistical differences in recurrence rate (1.4% for laparoscopic and 5.6% for open, P=0.25) and in overall (P=0.22) and disease-free survival (P=0.19) between the two groups. Type of approach was not an independent risk factor for recurrence and survival. CONCLUSIONS: Laparoscopic gastrectomy after endoscopic resection showed comparable oncologic outcomes to open approach while maintaining benefits of minimally invasive surgery. Thus, laparoscopic gastrectomy can be a treatment of choice for patients previously treated by endoscopic resection.

Renal artery stenosis is a rare cause of acute pulmonary edema. So-called flash pulmonary edema is associated with bilateral renal artery stenosis or stenosis in a single functioning kidney. Flash pulmonary edema has been recognized as an absolute indication for vascular intervention. A 33-year old man was admitted with acute shortness of breath. Renal angiography showed occlusion of the right renal artery. He underwent a right renal artery bypass graft. However, after the renal artery bypass graft, episodes of pulmonary edema recurred. A renal angiography showed complete obstruction of the right renal artery and bypass graft. The left renal angiography showed an intact renal artery and decreased kidney size.

BACKGROUND: Recently, the concept of health is being extended to physical, mental and social aspects, which leads people to pursue health positively behavior. But the evaluation of health condition shows a tendency to be biased to functional side. It means the absence of well being sensation that anyone feels like he has poor health. In this case, even if he is in physically good health, he is not rated as healthy. We analyzed the relationship between one's health state and the factors related with health perception including health behavior, mind and social environment. METHODS: For a month of May 1996, we surveyed those who visited for Periodic medical check-up at one general hospital in Seoul. The questionnaire consisted of the total of 25 items ; diet behavior, weight control, coffee, coke, tea, drug use of, smoking, drinking, exercise, leisure, safety belts use, jay walking, sleep, stress, personality, anxiety, depression, occupational satisfaction, relationships with family and friends. Five point scale is used as the answer of each question item with high point as good living behavior. Among 406 who had sincerely answered the questionnaire, we divided them into healthy and unhealthy group and compared with the point of each question item and with the laboratory data(obesity, blood pressure, hemoglobin, fasting blood sugar, cholesterol and ALT). RESULTS: Among 406, the number of those who perceived themselves to be healthy was 175(43.1%, healthy group) and the one of those who did not was 231(56.9%, unhealthy group), The difference between both groups was not significant in distribution of sex, age, academic career, income and religion. In laboratory data and living behavior they showed same results, also. But the points of unhealthy group were significantly lower than those of healthy group in coffee, coke, tee, drugs usage, exercise, leisure, stress, personality, anxiety, depression, occupational satisfaction and relationship with family and friends. So was the total point of all items of unhealthy group in comparison with that of health group. In the case of male, the points of unhealthy group were significantly lower in smoking, safety belt use, fay walking, sleeping as well as the above items. On the contrary, in the case of female, both groups were not significantly different all item except exercise and leisure. CONCLUSIONS: Health perception is influenced by psychosocial factors and living behavior more than by physical health. Therefore family physician must be concerned about patient's living behavior, mental and social problems and must make an effort to change their perception of health as well as physical improvement.

BACKGROUND: The deleterious cardiopulmonary side effects immediately after positioning in reverse Trendelenburg and CO2 intra-abdominal insufflation during a laparoscopic cholecystectomy are well tolerated in healthy patients but can lead to serious morbidity and mortality in patients with a limited cardiopulmonary reserve. Using a continuous and non-invasive cardiac output monitor based on partial CO2 rebreathing method, we investigated the immediate cardiopulmonary changes caused by positioning in reverse Trendelenburg and CO2 intra-abdominal insufflation during a laparoscopic cholecystectomy, and assessed the applicability of the partial CO2 rebreathing method for the measurement of cardiac output in a laparoscopic cholecystectomy. METHODS: The investigation was carried out on 11 patients undergoing a laparoscopic cholesystectomy. The control values of cardiac index (CI), cardiac output (CO), mean arterial pressure (MAP), heart rate (HR), central venous pressure (CVP), systemic vascular resistance (SVR), dynamic compliance (Cdyn), airway resistance (Raw), peak inspiratory pressure (PIP) and end tidal CO2 partial pressure (PETCO2) were measured in the supine position after induction with target-controlled infusion of propofol (5 microgram/ ml). Five minutes after positioning in reverse Trendelenburg and CO2 insufflation, the same cardiopulmonay variables were measured and compared with the control values. RESULTS: CI, CO and CVP were reduced 33.3%, 31.9% and 29.0%, respectively (P < 0.05). MAP and SVR were increased 39.8% and 154.1%, respectively (P < 0.05). Cdyn was reduced 38.0% (P < 0.05). Raw and PIP were increased 22.8%, and 34.8%, respectively (P < 0.05), whereas HR and PETCO2 remained unchanged. CONCLUSIONS: The non-invasive cardiopulmonary monitor using partial CO2 rebreathing method, could be used with ease and safety in a laparoscopic cholecystectomy.

Laryngopharyngeal reflux disease (LPRD) is common in laryngologic practice. In Korea, up to 1 out of every 5 patients who visit otorhinolaryngology clinic is supposed to have LPRD with symptoms and physical findings. Major symptoms of LPRD include hoarseness, cough, reflux symptom and mild dysphagia. Even though LPRD is common, its diagnosis may be difficult, because its symptoms are nonspecific and the laryngeal findings are not always associated with symptom severity. In Recent study, 66.4% of Patient who has LPRD also associated with esophageal motility disorders. Esophageal achalasia is a disease of unknown etiology characterized by an absence of peristalsis in the body of esophagus and nonrelaxing hypertension of the lower esophageal sphincter. Common cause is loss of ganglion cells in Auerbachs plexus. The classic triad of symptoms in achalasia includes dysphagia, regurgitation and weight loss. LPRD and esophageal achalasia have similar symptoms but have different treatment of choice. The Differentiation diagnosis of theses disease is important and should be established by history, radiologic examination and endoscopic examination. We recently assessed a 59-year-old female patient who complained of an epigastric pain, dysphagia and chronic cough. LPRD was initially diagnosed on Laryngoscopic examination and Reflux Symptom Index, but patient was not relieved of any symptoms after treatment of Proton Pump Inhibitor for 3 months. After high resolution manometry, esophageal achalasia was finally diagnosed. We report this case regarding the diagnosis and treatment with review of literatures because we have to think about esophageal motility disorders as a differential diagnosis in laryngology.
