    Abstract Pressurized intraperitoneal aerosol chemotherapy, named PIPAC, is now used in many centers around the world and as an intraperitoneal drug delivery system for treatment of peritoneal carcinomatosis. Recently, many of us have encountered problems during PIPAC procedures due to changes in material and production features of the original PIPAC nebulizer. Concomitantly, new PIPAC nebulizers proposed by other manufacturers are being launched on the market; which claim that they are the same as the original device in delivering PIPAC. However, these new devices are all different in terms of materials, technical characteristics and costs. We have considered that, to maintain the acquired results of PIPAC, we must ensure that the new systems are equivalent. The characteristics deemed essential by the expert group are as follows: 1: The nebulizer must be able to create droplets through an injector pressure between 10 and 20 bars, 2: The mean droplet size must be 3 micrometers, with 95% of the droplets between 0 and 10 micrometers, 3: The diffusion angle must be 70 degrees, which is the minimum.

    Abstract Background: The utility of computed tomography scans of the thorax, abdomen, and pelvis for gastric cancer staging has been recommended in many countries. However, the validity of the use of computed tomography thorax in gastric cancer staging has not been challenged.
    Methods: A retrospective review was conducted on our gastric cancer registry from 1998 till 2012 in the National University Hospital, Singapore. We performed computed tomography thorax only in selected cases. We defined isolated lung metastasis as the presence of suspicious findings on computed tomography thorax in the absence of metastasis elsewhere.
    Results: A total of 808 gastric cancer cases were reviewed. The mean age of the patients was 66 years (standard deviation 13.53), and 67% were male. In all, 238 patients (30%) had metastatic disease at presentation, and 1 (0.42%) had isolated lung metastasis. The most common site of metastasis was intra-abdominal (73.8%). Among the patients who underwent surgery, the overall distant recurrence rate was 30%, of which only 83 (30%) patients had lung metastasis and all had concurrent metastasis in an intra-abdominal site.
    Conclusion: The rarity of isolated lung metastasis in gastric cancer suggests the limited value of computed tomography thorax as a routine staging tool for gastric cancers.

    Abstract Patients with common variable immunodeficiency syndrome (CVID) have an increased risk of gastric adenocarcinoma. We describe a case of gastric adenocarcinoma in a 29-year-old man with CVID. He complained of dyspepsia and weight loss. Endoscopy showed an antral lesion. He underwent subtotal gastrectomy with postoperative adjuvant chemoradiation, and remained disease-free for three years. CVID is a predisposing factor for gastric adenocarcinoma. Gastric complaints are common among these patients and should be viewed seriously. Endoscopy is performed to detect any pathology. Premalignant conditions like chronic atrophic gastritis, intestinal metaplasia and dysplasia require regular endoscopic surveillance in these high-risk patients.

    Abstract Introduction: Acute appendicitis is the commonest cause for right lower abdominal pain. Clinical features, laboratory and imaging investigations are either not very sensitive or specific, and neither is therapeutic. We aimed to define the role of diagnostic laparoscopy in patients with right lower abdominal pain.
    Methods: Data was collected retrospectively from January 1, 2005 to December 31, 2005. Patients admitted to the Emergency Department and subsequently transferred to the Department of Surgery, National University Hospital, Singapore, with right lower abdominal pain and who eventually underwent diagnostic laparoscopy were evaluated.
    Results: 691 patients with right lower abdominal pain were admitted with suspected diagnosis of appendicitis. Diagnostic laparoscopy was undertaken in 103 patients aged 17-71 years old. Of the 83 females, 78 (94 percent) were premenopausal . Histology-proven acute appendicitis was diagnosed in 78 (75.7 percent) patients. Interestingly, within this group, 25.6 percent had other concomitant pathologies found on laparoscopy. 25 patients had a normal appendix; gynaecological causes accounted for pain in 15 of these 25 (60 percent) cases. In four (3.9 percent) patients, no pathology was found. Complication rate was 1.9 percent, which included ileus in two patients. In 32 (31.1 percent) patients, diagnostic laparoscopy altered the management plan, requiring either intervention or care by a subspecialty.
    Conclusion: Diagnostic laparoscopy is useful in evaluating patients with right lower abdominal pain, especially in those with equivocal signs of acute appendicitis. It also has the additional benefit of being therapeutic. Premenopausal women benefit the most from this procedure.

    Abstract Background & aims: Population endoscopic screening for gastric cancer is generally deemed not to be cost-effective except in Japan, where its prevalence is very high. However, in the absence of screening, patients present with advanced disease, and prognosis is poor. We conducted a cost utility analysis to determine whether endoscopic screening for stomach cancer in intermediate-risk population would be cost-effective and to better define the high-risk groups in the population who would benefit from such strategy.
    Methods: Cost-effectiveness analysis was performed by using a Markov Model. Simulation was performed on Singapore (intermediate-risk) population and various high-risk subgroups. Comparison was made between 2-yearly endoscopic mass screening program versus no screening. Data sources were extracted from relevant studies published from 1980-2004 identified via systematic PUBMED search. Main outcome measures were deaths caused by stomach cancer averted, cost per life saved, and incremental cost-effectiveness ratio expressed as cost per quality-adjusted life year (QALY) saved.
    Results: Screening of high-risk group of Chinese men (age-standardized rate, 25.9/100,000) from 50-70 years old is highly cost-effective, with cost benefit of United States $26,836 per QALY. Screening this cohort of 199,000 subjects prevents 743 stomach cancer deaths and saves 8234 absolute life years. Cost of averting 1 cancer death is United States $247,600. Cost-effectiveness was most sensitive to incidence of stomach cancer and cost of screening endoscopy.
    Conclusions: Screening of stomach cancer in moderate to high-risk population subgroups is cost-effective. Targeted screening strategies for stomach cancer should be explored.
