  • The change in the position of the abdominal organs due to movement by respiration is one of the reasons behind inaccurate irradiation of organs during radiotherapy (RT). Although studies in human medicine have revealed on the respiratory movements of abdominal organs, there is little information and no reference data for dogs. The purpose of this study was to establish the reference values of abdominal organs movement in various postures using computed tomography (CT), and to compare the movements of organs between dorsal recumbency and ventral, right and left lateral recumbency during respiration. CT images for kidney, adrenal gland, medial iliac lymph node, urinary bladder, gallbladder, liver, stomach, and thoracic and lumbar vertebral body of five beagle dogs were acquired. The movements of organs were evaluated by comparing the end-expiratory and end-inspiratory images. Movements of the organs were evaluated by dividing it into right-to-left, dorsal-to-ventral, and cranial-to-caudal directions. The movements of abdominal organs according to the change in postures and respiration were establish. The movement of the bilateral organs was the least when the organs were in the downward position (p < 0.017). The movement of cranial-to-caudal direction was greater than the movement of the other directions in most of the organs. Data obtained in this study may be useful in selecting the appropriate posture that can reduce the movements of organs to be treated with RT, and the data could be useful for setting the planning target volume to consider the movements of the abdominal organs by respiration.

  • The purpose of this study is to construct fundamental information about the ultrasonographic diagnosis for extrinsic and intrinsic abdominal disease. Normal ultrasonography of liver, gall bladder, spleen, kidney, urinary bladder, stomach, pylorus, duodenum, and heart of 4 cynomolgus monkey(Macaca fascicularis) were determined by use of ultrasonography. One cynomolgus monkey was autopsied at the time of euthanasia which is performed 24 hours after ultrasonography, and above mentioned organs were measured actually. In ultrasonography of cynomolgus monkey, the gall bladder was 17.5 cm long, and 6.6 cm wide. The width of spleen was 8.8 mm. The right kidney was 35.5 mm long, 23.7 mm wide, and 15.2 mm deep. The ultrasonographic measurements of the left kidney in calves was similar. The urinary bladder was 27.7 mm long, and 20.5 mm wide.

Normal ultrasonography of liver, gall bladder, spleen, kidney, urinary bladder, stomach, pylorus, duodenum, and heart of 5 common marmoset(Callithrix jacchus) were determined by use of ultrasonography. One common marmoset was autopsied at the time of euthanasia which is performed 24 hours after ultrasonography, and above mentioned organs were measured actually. In ultrasonography of common marmoset, the gall bladder was 8.2 cm long, and 3.4 cm wide. The width of spleen was 4.3 mm. The right kidney was 22.2 mm long, 16.1 mm wide, and 9.3 deep.

  • Fibrinopurulent peritonitis and abdominal abscesses associated with Streptococcus (S.) equi subsp. zooepidemicus is reported in a 1-year-old female thoroughbred horse. The horse died after showing 5-day history of the cold, severe abdominal distention, abdominal breathing, hyperthermia, anorexia, and loss of intestinal sound. At necropsy, several liters of turbid yellowish green fluid were seen in the abdominal cavity. Yellowish creamy and fibrinous or bloody materials were presented on the serosa of various abdominal organs that were intensively adhered with each other. Spleen and mesenteric lymph node were remarkably enlarged. Affected lobes of the lung showed severe congestion, hemorrhage and doughy consistency. Histologically, the lung showed hemorrhagic pneumonia with diffuse congestion and edema. Severe diffuse fibrinopurulent peritonitis with Gram-positive bacterial cocci and adjacent fibrosis were showed in the serosa of various abdominal organs such as liver, spleen, stomach, and intestine. And multifocal abscess pouches were presented in the granulation tissue of abdominal viscera. S. equi subsp. zooepidemicus was isolated from the peritoneal swab, abdominal organs, and lung. Hematogenous dissemination of bacteria from hemorrhagic pneumonia is proposed as the route of infection in this case.

  • The ultrasonography(US) is one of very important item for abdominal evaluation. Especially for the routine check of the abdomen, the US becomes the essential part of the precedure. Though the abdominal US is simple and easy, its value is very high for detection of various morphological changes of abdominal organs. The study techniques of US, common abdominal abnormalities, standardization of image interpretation, and clinical significance of the lesions, etc, were discussed.

  • 4, 8, 12, 20 주령의 미성숙 미니돼지에서 방사선과 초음파를 이용하여 복부 주요 장기의 형태학적 특징을 살펴보았다. 방사선 검사는 전반적인 장기의 형태를 확인하는 데 이용되는 가장 기본적이고 단순한 방법이다. 기본 복부방사선 사진에서 이용되는 평가해야 할 항목들은 우선 전반적인 복부세부음영의 정도, 간, 위, 비장, 신장, 방광, 장들의 위치, 크기, 형태, 변연, 후복강 평가이다. 초음파 검사는 이러한 주요 장기들의 내부 실질을 평가하는 데 주로 사용된다. 미니돼지는 개와 고양이와 비교했을 때 유사한 소견을 가진 것을 확인하였다.

  • In this paper, we propose an automatic hierarchical organ segmentation method on abdominal CT images. First, similar atlases are selected using bone-based similarity registration and similarity of liver, kidney, and pancreas area. Second, each abdominal organ is roughly segmented using image-based similarity registration and intensity-based locally weighted voting. Finally, the segmented abdominal organ is refined using mask-based affine registration and intensity-based locally weighted voting. Especially, gallbladder and pancreas are hierarchically refined using location information of neighbor organs such as liver, left kidney and spleen. Our method was tested on a dataset of 12 portal-venous phase CT data. The average DSC of total organs was $90.47{\pm}1.70%$. Our method can be used for patient-specific abdominal organ segmentation for rehearsal of laparoscopic surgery.

  • Background: This study analyzed and described the clinical characteristics and surgical outcomes of diaphragmatic hernia (DH) repair according to the operative approach. Methods: After excluding cases with a combined approach and hiatal hernias, we analyzed 26 patients who underwent DH repair between 1994 and 2018. The baseline and perioperative characteristics of the thoracic approach group and the abdominal approach group were described and analyzed. Results: Fifteen of the 26 patients were treated through the thoracic approach, including 5 patients who underwent video-assisted thoracic surgery (VATS). Eleven patients underwent the abdominal approach. The thoracic approach was associated with a longer duration of DH than the abdominal approach (2 vs. 0.1 months), herniation of the right-sided abdominal organs, and herniation of the retroperitoneal organs. During the median follow-up of 23 months, there was no recurrence of DH. Conclusion: The surgical approach should be chosen considering the duration of DH and the location of herniated organs. VATS might be a safe and feasible option for repairing DH.

  • 애반닷불이 (Luciola lateraιs Mot.) 성충과 유충 발광기관의 현미경 관찰결과와 발광기관과 신경계의 관계는 다음파 같다. 유충의 발광기관은 복부 8번째 마디 좌우 등쪽 측면에 한 쌍이 존재하였으며 복부 8번째 신경 절로부터 나온 한쌍의 말초신경에 지배받는다. 발광기관의 모양은 구형 혹은 구형과 유사한 형태이며 발광기관 주변에는 과립들이 있었다. 이러한 과립들은 유충령기가 높아갈수록 많아져 용화하기 위하여 지상에 상륙한 유충의 경우, 하나의 층을 형성하고 있는 것처럼 보였다. 그리고 발광기관에는 근육이 존재하며 기관과 기관소지도 발견되었다. 성층의 발광기관은 수컷의 경우 복부 5, 6째 마디에 있으며 암컷의 경우는 5째마디에만 존재했다. 성충의 발광기관은 발광세포 충(약 70$\mu m$의 두께)과 반사충(약 40$\mu m$의 두께)으로 구성되어 있었다. 그리고 유충의 발광기관 에서는 볼 수 없었던 기관지소기관(tracheal end organ)이 존재하였다. 복부 5째 마디의 발광기관 은 복합신경절 (유층의 6째, 7째,8째 복부마디의 신경절들이 융합된) 앞쪽에서 나온 두 쌍의 말 초신경에 의해 지배되며, 복부 6째 마디(수컷)의 발광기관은 복합신경절의 뒤쪽에서 나온 한쌍 의 말초신경에 지배받는다.

  • It is well known that the celiac plexus block is specially useful for relieve intractable upper abdominal pain caused by upper abdominal visceral malignancy or upper abdominal metastasis from distant organs. But in cases of lower abdominal or pelvic metastasis from upper abdominal malignancy, the lower abdominal intractable pain is remained after the successful celiac plexus block. We have reported 7 cases of celiac plexus block combined with lumbar sympathetic ganglion block, among the 305 cases of the celiac plexus block from 1968 to Nov. 1987, performed in patients with lower abdominal or back pain due to carcinomatosis of lower abdominal metastatic malignancy, that their results were excellent for pain relief.
