Four cases of newborn with tension pneumothorax induced by a conventional ventilator were admitted to our nursery from January 1. 1992 to June 30. 1992 and they were managed by high frequency ventilator (Infrasonic Infant Star Ventilator). In contrast, four cases of newborn with tension pneumothorax who were continuously on the conventional ventilator, were included as a control group. They were admitted to our nursery from July 1. 1991 to december 31. 1991 and they were managed by conventional ventilator with conservative treatment. 1) In the control group, who were continuously managed by the conventional ventilator after thoracostomy with water seal drainage, we changed ventilator setting appropriately in control group but they had poor arterial blood gas analysis. The arterial blood gas analysis within 24hr/within 72hr in control group were pH 7.192/7.195, Paco2 72.15/82.25, PaO2 78.92/83.875, HCO3-26.975/27.925 and conventional ventilator care did not show any definite benefit for improvement of arterial blood gas analysis and tension pneumothorax as well. 2) Two cases in control group expired on the 6th day of thoracostomy without any resolution of tension pneumothorax. 3) In contrast, four cases with tension pneumothorax managed by high frequency ventilator were improved. Tension pneumothorax and arterial blood gas analysis to normalize from 6hr of high frequency ventilation and four cases of tension pneumothorax were completely reabsorbed within 4days.

Laparoscopic distal gastrectomy for gastric cancer has rapidly gained popularity because of its short-term benefits, including less blood loss, less postoperative pain, earlier postoperative recovery, and shorter hospital stay, compared to the conventional open method. Although the long-term results of phase III trials have yet to be published, laparoscopic distal gastrectomy is now considered to be accepted for early-stage gastric cancer. As advances in instruments and the accumulation of laparoscopic experience increase, laparoscopic distal gastrectomy is being used for advanced gastric cancer. However, due to the technical difficulty of performing D2 lymphadenectomy, this application remains controversial. Well-designed clinical trials will clarify the surgical feasibility and oncological safety of laparoscopic distal gastrectomy for advanced gastric cancer in the near future.

Although the proportion of early gastric cancer has increased, that of advanced gastric cancer (AGC) is still high. The overall prognosis of AGC has gradually improved over the past decades with advances in surgical techniques as well as multimodality treatments. Nevertheless, the outcome of AGC still remains poor and worldwide standard treatment guideline has not been established. Radical gastrectomy is the gold standard of management or gastric cancer worldwide, as the complete surgical removal of tumors (R0 resection) confers the only chance for cure. However, the extent of lymph node dissection has been debated between East and West. Radical gastrectomy with extended D2 lymphadenectomy is the accepted standard in Eastern countries, whereas limited D1 lymphadenectomy with chemoradiotherapy is more frequently used in Western countries. Role of splenectomy and laparoscopic surgery for AGC is still debatable and should be proved by long-term oncologic outcomes from large-scale randomized controlled trials.

The incidence of early gastric cancer has been increasing in Korea, and minimally invasive surgeries such as endoscopic resection and laparoscopic surgery, have also been increasing in terms of operations performed. Recent studies show that laparoscopic gastrectomy is a safe technical alternative to open gastrectomy for early gastric cancer with a lower overall complication rate and enhanced postoperative recovery. A retrospective large scale multi-center study from Korean Laparoscopic Gastrointestinal Study (KLASS) Group reported excellent short-term outcome including feasibility, safety, and effectiveness as well as satisfactory long-term oncologic outcome. We are still waiting for the results from randomized controlled trials of laparoscopic versus open gastrectomy for early gastric cancer patients designed by KLASS which will provide the conclusive evidential support for laparoscopic surgery.

Leiomyosarcoma of the inferior vena cava(IVC) is a rare tumor and has a poor prognosis. Recently, newer imaging modalities including ultrasound, computed tomographic scan, magnetic resonance imaging and cavovenography make it possible to detect in its early stage of proression. The best therapeutic management is surgical resection and the effects of postoperative adjuvant therapies on patients' survival are still debatable. We report herein our experience of 45-year-old woman whose leiomyosarcoma of the IVC was successfully resected without reconstruction of the IVC.

Gastritis cystica profunda (GCP) is an uncommom hyperplastic lesion, which is located within the submucosa. GCP may occur several years after previous gastric surgery. In some reported cases, it was a premalignant condition and may lead to carcinoma of the stomach. We report a case of a 54-year-old man with epigastric pain and dyspepsia. He had undergone peritoneal dialysis for end stage renal disease about 13 years prior. An Upper gastrointestinal endoscopy showed elevated lesion at the gastric antrum, looking like an advanced gastric cancer or gastrointestinal stromal tumor. Endoscopic biopsy results were tubular adenoma with low-grade dysplasia. When followed up 9 months later, the lesion had increased in size and symptoms remained. We therefore performed a subtotal gastrectomy. The final biopsy was adenocarcinoma arising in GCP.

Owing to the introduction of national screening program, the detection rate of early gastric cancer (EGC) has been rapidly increased in Korea. Laparoscopic gastrectomy has been widely accepted as one of the standard treatments of EGC regardless of the risk of lymph node metastasis. Benefits of laparoscopic surgery included less pain, earlier recovery, lower complication rate than open surgery. Studies from Korean Laparoscopic Gastrointestinal Surgery Study Group (KLASS) reported short-term outcome including feasibility, safety, and effectiveness as well as satisfactory long-term oncologic outcome. Ongoing prospective randomized controlled trials for early and advanced gastric cancer patients designed by KLASS will provide the evidence of the role of laparoscopic surgery.
