PURPOSE: Peritoneal recurrence has been reported to be the most common form of recurrence of gastric cancer. Peritoneal recurrence can generally be suggested by several types of image studies and also if there is evidence of ascites or Bloomer's rectal shelf. It can be confirmed by explorative laparotomy, but diagnostic laparoscopy is a good alternative method and laparoscopic surgery has also been widely used. We reviewed and analyzed the ability of diagnostic laparoscopy to detect peritoneal recurrence or carcinomatosis, and especially for gastric cancer. MATERIALS AND METHODS: We performed a retrospective review the 45 gastric cancer patients who were operated via diagnostic laparoscopy between 2004. 2. and 2009. 3. We analyzed the perioperative clinical characteristics and the accuracy of the diagnostic methods. RESULTS: The study groups included 14 patients who had confirmed gastric cancer, but they suspected to have carcinomatosis, and 31 patients who had previously underwent gastric resection, but they suspected to have recurrence. The mean operation time was 44.1+/-6.9 minutes and the mean postoperative hospital stay was 2.7+/-.8 days. There was one case of operation-related complication and no postoperative mortality occurred. The sensitivities for detecting peritoneal recurrence or carcinomatosis were 92.1% for diagnostic laparoscopy, 29.7% for detecting ascites and rectal shelf on the physical examination, 86.5% for abdominal computed tomography, 69.2% for PET CT and 18.8% for CEA. CONCLUSION: Diagnostic laparoscopy does not require a long operation time or a long hospital stay, and it showed a low complication rate in our study. It has high sensitivity for detecting peritoneal recurrence of gastric cancer. It can be an alternative diagnostic confirmative method and it is useful for deciding on further treatment.

Sleep disturbance and restless legs syndrome (RLS) among uremic patients is known to be high, but data on the prevalence, clinical significance, and causative factors are limited. A semiquantitative sleep and RLS questionnaire was distributed to 62 chronic hemodialysis(HD) patients. 74.5N had sleep complaints and frequent awakening was the most frequent specific sleep complaints followed by daytime sleepiness. Presence of diabetes mellitus(DM), RLS, depres- sion, high CRP level, low intact parathyroid hormone level, low subjective global assessment score, and short HD duration were associated with more sleep complaints. 58.3N had RLS and presence of DM, low serum albumin level were also associated with more severe RLS. But Kt/V, protein catabolic rate, hematocrit, plasma bicarbonate level, use of erythropoietin and sleep medication were not associated with sleep complaints and RLS. Sleep problems and RLS are comrnon in HD patients and seem to be associated with malnutrition. Presence of DM, de- pression, and RLS are likely to contribute the high prevalence of sleep disturbance.

PURPOSE: Laparoscopic gastrectomy has been common treatment modality for gastric cancer. But, most surgeons tend to perform laparoscopy-assisted distal gastrectomy using epigastric incision. Delta-shaped anastomosis is known as intracorporeal gastroduodenostomy, but it is technically difficult and needed many staplers. So we tried to find simple and economical method, here we report on the results of liner-shaped gastroduodenostomy in totally laparoscopic distal gastrectomy. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 25 patients who underwent totally laparoscopic distal gastrectomy using liner-shaped anastomosis at School of Medicine, Ajou University between January to October 2009. The indication was early gastric cancer as diagnosed by preoperative workup, the anastomoses were performed by using laparoscopic linear stapler. RESULTS: There were 12 female and 13 male patients with a mean age of 55.6+/-11.2. The following procedures were performed 14 laparoscopic gastrectomies, 11 robotic gastrectomies. The mean operation time was 179.5+/-27.4 minutes, the mean anastomotic time was 17.5+/-3.4 minutes. The mean number of stapler cartridges was 5.6+/-0.8. Postoperative complication occurred in one patient, anastomotic stenosis, and the patient required reoperation to gastrojejunostomy. The mean length of postoperative hospital stay was 6.7+/-1.0 days except the complication case, and there was no case of conversion to open procedure and postoperative mortality. CONCLUSIONS: Linear-shaped gastroduodenostomy in totally laparoscopic distal gastrectomy is technically simple and feasible method.

BACKGROUND: The objectives of this study are to determine the positive rate of HBV serologic markers and infection rate, and to evaluate the efficiency of hepatitis B vaccination. METHODS: Study subjects included 905 persons in 1988-1989 and 744 persons in 1993-1994 living in typical rural communities in Korea. Three serologic markers(HBsAg, anti-HBs, anti-HBc) were tested by radio-immunoassay(RIA). Supplemental informations were collected by self-administered questionnaire and interview on age, sex, history and frequency of vaccination. RESULTS: 1) Among non-vaccinees, HBsAg, anti-HBs, anti-HBc positive rates and infection rate in 1993-1994/1988-1989 were 5.4%/6.5%, 49.1%/45.9%, 48.3%/44.1% and 60.6%/54.5% respectively. The infection rate showed a trend of continuous increase as the age increased, while statistically significant increase was seen over age 20. 2) Overall vaccination rate was 18.1% in 1988-1989 and 37.9% in 1993-1994, showing statistically significant increase in vaccination rate. The rate in younger age groups were higher than in older groups in 1988-1989, but there was no difference by age groups in 1993-1994. Among vaccinees, anti-HBs only positive group occupied 42.7% in 1988-1989 and 41.3% in 1993-1994. HBs Ag negative and anti-HBc positive group occupied 26.2% in 1988-1989 and 36.73% in 1993-1994. CONCLUSION: 1) Among non-vaccinees, HBsAg positive rate was decreased, but the hepatitis B infection rate was not decreased. 2) The test for selection of eligible person of vaccination and education program for completion of vaccination schedule must be reevaluated to improve the efficiency of hepatitis B vaccination.

Iatrogenic vertebro-vertebral arteriovenous fistula (AVF) is an uncommon complication resulting from various procedures such as central venous catheter insertion. The incidence may be underestimated since the diagnosis is not easy because of its rarity. A central venous catheterization via the internal jugular vein was attempted in a 43-year-old female who presented for intracranial aneurysmal clipping under general anesthesia. Inadvertent arterial puncture was recognized as pulsatile arterial blood flow through the needle. The needle was removed and local compression was applied to the puncture site. The catheter was inserted via the right femoral vein. After surgery, the patient recovered from anesthesia without any complications. On postoperative day 5, thrill and bruit on the right side of the neck were noted on physical examination. Angiography confirmed vertebro-vertebral AVF, which was successfully obliterated with a stent 3 months later.

A case of primary choriocarcinoma in the stomach of a 60-year-old male is herein presented. The tumor was diagnosed as a choriocarcinoma by histologic examination and the immunohistochemical method of endoscopic biopsy of a specimen. Serum alpha- fetoprotein and beta-human chorionic gonadotropin were found to be significantly elevated. Multiple distant metastasis of the liver, intraabdominal lymph nodes and malignant ascites were also discovered. The high alpha-fetoprotein level in the serum might have been due to the coexistence of embryonal cell carcinoma or hepatoid adenocarcinoma or both in the stomach.

Delftia acidovarans is aerobic, nonfermentative Gram-negative rod commonly found in soil and water. Generally it is nonpathogenic but it unusually can cause bacteremia in immunocompromised patients. We present a case of peritonitis due to D. acidovorans in a patient on continuous ambulatory peritoneal dialysis. A 75-year-old woman was admitted with abdominal pain and cloudy peritoneal effluent. She was empirically treated with intraperitoneal (IP) cefazolin and ceftazidime, and then IP ceftazidime and oral ciprofloxacin, but peritonitis did not improve. Seven days after admission, D. acidovorans was identified from the peritoneal effluent, which was sensitive to amikacin, ceftazidime, ciprofloxacin and imipenem. Catheter removal was considered with regard to poor response to adequate antibiotics; however, 4 days after changing to IP imipenem/cilastatin, abdominal pain, the leukocyte count of peritoneal effluent and C-reactive protein decreased. She was treated with imipenem/cilastatin for two weeks and discharged with the dialysis catheter intact.

BACKGROUND: Combination of propofol and remifentanil is an ideal regimen for total intravenous anesthesia, and the bispectral index (BIS) has been used as an indicator of the sedative state during anesthesia. This study examined the effect of remifentanil on the mean arterial pressure (MAP), heart rate (HR) and BIS to laryngoscopy and tracheal intubation with 4microgram/ml of fixed target effect-site concentration infusion of propofol. METHODS: In this double-blind study, fifty-one ASA physical status I-II patients, aged 20-60 yr undergoing elective surgery were randomly assigned to one of four groups according to the target effect-site concentration of remifentanil (0, 2, 3, 4 ng/ml). The target-controlled infusion (TCI) of remifentanil was initiated after the effect-site concentration of propofol was maintained with 4microgram/ml. After target effect-site concentration of remifentanil was reached, a neuromuscular blockade was produced by rocuronium 1 mg/kg and tracheal intubation was performed after 90 seconds. MAP, HR and BIS were measured at pre-induction, after reaching target effect-site concentration of propofol and remifentanil, before and after tracheal intubation. RESULTS: The changes of MAP, HR and BIS after tracheal intubation were negatively correlated with remifentanil effect-site concentration. CONCLUSIONS: Remifentanil attenuated the hemodynamic responses due to tracheal intubation and decreased BIS after tracheal intubation in a comparable dose-dependent fashion.

Primary malignant melanoma of the esophagus(PMME) is an extremely rare but aggressive disease that composes less than 0.1% of all primary malignant neoplasm of the esophagus. PMME was first reported in 1906 and nearly 180 cases of primary esophageal malignant melanoma have been published in the medical literature. Symptoms of the primary malignant melanoma of the esophagus mimic that of any malignant obstructing lesion of the esophagus and the metastatic spread by lymphatics and vascular routes are common. Resection of the tumor with an anastomotic procedure seems to be the treatment of choice, however prognosis is poor. At present, chemotherapy and immunotherapy have no major role in treatment. We report a case of 67-year-old man with primary malignant melanoma of the esophagus originated from esophageal melanosis with a review of the literature.

Here, we report a case of pleural paragonimiasis that was confused with tuberculous pleurisy. A 38-year-old man complained of a mild febrile sensation and pleuritic chest pain. Radiologic findings showed right pleural effusion with pleural thickening and subpleural consolidation. Adenosine deaminase (ADA) activity in the pleural effusion was elevated (85.3 IU/L), whereas other examinations for tuberculosis were negative. At this time, the patient started empirical anti-tuberculous treatment. Despite 2 months of treatment, the pleural effusion persisted, and video-assisted thoracoscopic surgery was performed. Finally, the patient was diagnosed with pleural paragonimiasis based on the pathologic findings of chronic granulomatous inflammation containing Paragonimus eggs. This case suggested that pleural paragonimiasis should be considered when pleural effusion and elevated ADA levels are observed.
