  • The main objective of modern reproductive technologies in pig reproduction is to increase reproductive efficiency and rates of genetic improvement. They also offer potential for greatly extending the multiplication and transport of genetic materials and the conservation of unique genetic resources in reasonably available forms for possible future use. The development and refinement of these technologies is concentrating on gamete and embryo collection, sorting and preservation, in vitro production of embryos, culturing, manipulation of embryos (splitting, nuclear transfer, production of chimeras, establishment embryo stem cells, and gene transfer) and embryo transfer. Also, the development of these novel technologies is facilitated by modern equipment for ultrasonography, microscopy, cryopreservation, endoscopy, and flow cytometry, microinjectiors, micromanipulators and centrifugation. The real impact on herd productivity will come from combining new reproductive techniques with powerful DNA technologies. The new reproductive techniques will allow a rapid turnover of generations, whereas the DNA technology can provide selection, which does not need phenotypic information when the selection decisions are made.

  • Shunt infections are a common complication of ventriculoperitoneal (VP) shunts, but the formation of a brain abscess related to a shunt system is very rare. A 44-year-old woman had a VP shunt inserted for hydrocephalus secondary to a subarachnoid hemorrhage. She suffered an episode of meningitis and sepsis 8 months after the shunt operation. After recovering from the meningitis, she complained of a loss of cognitive function. An enhancing mass was found in the frontal lobe, around the frontal horn of the lateral ventricle, and the ventricular catheter was embedded inside the mass. The ventricular catheter and cerebral abscess were removed using neuroendoscopy. We present an interesting case of a shunt-related brain abscess which illustrates the usefulness of neuroendoscopy.

  • Endoscopic treatment is a minimally invasive treatment for managing patients with vesicoureteral reflux (VUR). Although several bulking agents have been used for endoscopic treatment, dextranomer/hyaluronic acid is the only bulking agent currently approved by the U.S. Food and Drug Administration for treating VUR. Endoscopic treatment of VUR has gained great popularity owing to several obvious benefits, including short operative time, short hospital stay, minimal invasiveness, high efficacy, low complication rate, and reduced cost. Initially, the success rates of endoscopic treatment have been lower than that of open antireflux surgery. However, because injection techniques have been developed, a recent study showed higher success rates of endoscopic treatment than open surgery in the treatment of patients with intermediate- and high-grade VUR. Despite the controversy surrounding its effectiveness, endoscopic treatment is considered a valuable treatment option and viable alternative to long-term antibiotic prophylaxis.

PANENDOSCOPIC EXAMINATION OF THE UPPER AERODIGESTIVE TRACT FOR THE DETECTION OF SECOND PRIMARY CANCERS IN HEAD & NECK CANCER PATIENTS (두경부암종 환자에서 상부 호흡소화기관에 병발한 원발성 중복암의 진단적 종합내시경검사)

  • The increasing incidence of multiple primary carcinomas occuring in the upper aerodigestive tract is well documented, with the accepted incidence being as high as 20-30%. The fiberoptic endoscopy has also enabled visualization of areas previously inaccessible without general anesthesia. A prospective panendoscopic examination of the upper aerodigestive tract was peformed on 104 patients with squamous cell carcinoma of head & neck in our hospital between 1989 and 1994. Five second primary cancers (4.8% :2 stomach, 2 esophagus, 1 lung cancers) were detected endoscopically. These finding should reinforce the belief that head & neck cancer is a panmucosal disease of the aerodigestive tract that silent second primary cancers are not uncommon. So every effort should be done to detect second primary cancers in head & neck squamous cell carcinomas. Panendoscopy has proved valuable in achieving that.

  • Unintentional foreign body ingestion is common in children, and coins are the most common foreign body ingested. Foreign body remaining in the esophagus may be associated with mucosal ulceration or esophageal obstruction and can potentially lead to significant morbidity and even death. Removal of esophageal foreign body is therefore generally recommended. Several methods are utilized including esophagoscopy in operating room, flexible endoscopy in out patient setting, fluoroscopic Foley catheter technique, and advancement using bougienage. We report two cases of esophageal foreign body(paduk stone) which were hard to be removed by usual esophagoscopic removal. Successful removal was accomplished with the aid of Fogarty catheter under the general anesthesia.

  • Cholangiocarcinoma, though very rare in Western countries, is one of the commonest liver malignancies in Southeast Asia, especially in Thailand. More than half of the patients present with advanced stage disease. Given the poor treatment outcomes of adjuvant therapeutic options, many patients undergo only biliary drainage for palliative treatment. Clinical characteristics and treatment outcomes after biliary stenting were here analyzed for a total of 224 uresectable cholangiocarcinoma cases, 58.9% in men. The mean age was 61.5 years. Hilar involvement was the most common location. The patients underwent biliary drainage using plastic and metallic stents equally, early stent occlusion being encountered in 21.4% and 10.7%, respectively. The median survival time was 4.93 months for patients who received plastic and 5.87 months for patients who received metallic stents.

  • Osteomas are benign osteogenic neoplasms that usually occur as solitary craniofacial lesions. Multiple osteomas are rare, particularly those that do not occur as part of an associated syndrome. We report a case of a 72-year-old woman who presented with multiple bony protrusions over the forehead and scalp. She denied any diagnosis of syndromes that are known to be associated with osteomas. Surgical excision was performed by endoscopically resecting more than 30 osteomas of the frontal and bilateral parietal bones. Compared with conventional surgical excision through a direct incision, endoscopic-assisted surgery is a simple and effective method for the treatment of multiple craniofacial osteomas and is associated with excellent cosmetic outcomes and no neurovascular complications.

  • Gastric cancer is rare during pregnancy, and often advanced upon presentation. A Krukenberg tumor presents a diagnostic and therapeutic challenge in the pregnant patient. We present a case of a 38-year-old woman at 22 weeks' gestation who presented with worsening epigastric pain, and was found to have a left pelvic mass on ultrasound, which was confirmed by magnetic resonance imaging. She went into active labor and delivered a viable infant via vaginal delivery. An exploratory laparotomy revealed a large mass originating from her left ovary and diffuse thickening of the lesser curvature of the stomach. Frozen section investigation revealed the presence of signet cell adenocarcinoma. Subsequent upper endoscopy showed linitis plastica, while biopsy confirmed the presence of adenocarcinoma. In conclusion, the occurrence of gastric cancer in pregnancy is rare despite extremely common symptoms. The management poses a challenge because of the need for early treatment, and the continuation of the pregnancy.

  • Helicobacter pylori(H. pylori) is the causative agent of chronic gastritis and the single most important factor in peptic ulcer disease, however, the pathogenetic mechanisms underlying H, pylori infection are not well understood. Futhermore, there is a strong association between H. pylori infection and gastric cancer. Various diagnostic methods for detecting H. pylori infection are available. These can be divided into invasive methods, requiring endoscopy, and non-invasive tests, mainly 13C-urea breath tests and serologic detection of antibodies. Rapid urease test is the most recommendable endoscopic test for the diagnosis of H. pylori infection, presently. CLO test kit is the represent of rapid urease test kits. The principles of CLO test kit is that hydrolysis of urea by urease Is detected by a dye indicators showing a color change. Our device is used same principle but we improved the reaction time is more faster and positive color change is more distinctive from the color of the negative specimen. So, this kit is more reliable because it response faster and accuracy.
