Normal and abnormal ultrasonographic findings that mimic small Intestinal Intussusception in the dog.
Journal of the American Animal Hospital Association, 2004Co-Authors: Michail Patsikas, Lysimachos G. Papazoglou, Nickolaos G Papaioannou, A. DessirisAbstract:On ultrasonographic examination of the abdomen, the appearance of healthy intestine, enteritis secondary to an Intestinal foreign body, and postpartum involution of the uterus may be visualized in some imaging planes as a target-like structure that is subsequently misinterpreted as Intestinal Intussusception. To avoid misdiagnosis, the ultrasonographer should ensure multi-plane scanning of the lesion, paying particular attention to the completeness of the lesion's peripheral ring structure and the overall width of the concentric rings of the target-like lesion. The presence of a semilunar or G-shaped hyperechoic center and the visualization of the inner intussusceptum (extending into the Intussusception lumen) can be useful ultrasonographic findings that distinguish an Intussusception from other lesions or from healthy tissues. These principles are illustrated through the following case presentations.

Ultrasonographic findings of Intestinal Intussusception in seven cats
Journal of feline medicine and surgery, 2003Co-Authors: Michail Patsikas, Lysimachos G. Papazoglou, Nikolaos Papaioannou, Ioannis Savvas, George Kazakos, A. DessirisAbstract:The medical records of seven cats with Intestinal Intussusception that were diagnosed by abdominal ultrasonography and exploratory laparotomy were reviewed. In transverse ultrasonographic sections the Intussusception appeared as a target-like mass consisting of one, two or more hyperechoic and hypoechoic concentric rings surrounding a C-shaped, circular or non-specific shaped hyperechoic centre. Part of the intestine representing the inner intussusceptum, located close to the hyperechoic centre and surrounded by concentric rings, was also detected. In longitudinal sections the Intussusception appeared as multiple hyperechoic and hypoechoic parallel lines in four cases and as an ovoid mass in three cases. In one case the ovoid mass had a ‘kidney’ configuration. Additional ultrasonographic findings associated with Intestinal Intussusception included an Intestinal neoplasm in one cat. The results of the present study demonstrate that the ultrasonographic findings of Intestinal Intussusception in cats bear some similarities to those described in dogs and humans, are relatively consistent, and facilitate a specific diagnosis.

Ultrasonographic Signs of Intestinal Intussusception Associated With Acute Enteritis or Gastroenteritis in 19 Young Dogs
Journal of the American Animal Hospital Association, 2003Co-Authors: Michail Patsikas, Lysimachos G. Papazoglou, George Kazakos, Samuel Jakovljevic, Nicolaos Moustardas, A. DessirisAbstract:The ultrasonographic pattern of Intestinal Intussusception was studied in 19 young dogs with acute enteritis or gastroenteritis. The Intussusception was observed to be a target-like mass consisting of a hyperechoic or anechoic center surrounded by multiple hyperechoic and hypoechoic concentric rings in transverse sections. In longitudinal sections, the Intussusception appeared as multiple hyperechoic and hypoechoic parallel lines, as a tumor-like or pseudokidney mass, and as a trident-like configuration. Ultrasonography may provide a sensitive, specific, and accurate method of diagnosing Intestinal Intussusception in young dogs.

Spontaneous reduction of Intestinal Intussusception in five young dogs.
Journal of the American Animal Hospital Association, 2008Co-Authors: Michail Patsikas, L. G. Papazoglou, Katerina K. Adamama-moraitouAbstract:Five, 3- to 8-month-old dogs had clinical and ultrasonographic findings consistent with Intestinal Intussusception, but findings were negative on exploratory celiotomy. Ultrasonography had revealed a target-like mass (median maximal diameter 25 mm) on transverse section and multiple hyperechoic or hypoechoic parallel lines (median length 36.8 mm) on longitudinal section. Blood flow in the intussuscepted bowel was detected in most of the cases. In dogs with similar findings, the authors recommend ultrasonographic reexamination of the abdomen after general anesthesia (but before surgery) to exclude spontaneous reduction of the Intussusception.

Experience of Diagnosis and Treatment of Intussusception in Children
Galician Medical Journal, 2016Co-Authors: O. Fofanov, O. Borys, R.i. Nykyforuk, Vyacheslav Fofanov, I. Krasivs'kijAbstract:The objective of the research was to establish the causes of complications of Intestinal Intussusception in children as well as to determine the optimal diagnostic and treatment strategy. Materials and methods. The analysis of medical records and examinations of 100 children with Intestinal Intussusception at the age of 1 month to 17 years who were treated at the clinic of pediatric surgery of the Ivano-Frankivsk National Medical University was made. Ileocecal Intussusception was diagnosed in 77 children; 13 patients had small Intestinal Intussusception; there were no patients with colonic Intussusception; in 10 patients the localization of Intussusception was not established. Treatment of Intestinal Intussusception was performed urgently immediately after the diagnosis. High priority was given to conservative treatment (74 patients); it was effective in 64 (86.5%) patients. The remaining 36 patients underwent surgery, 9 (25%) of them underwent a laparoscopic disinvagination. In 27 cases open surgery – disinvagination – was used. Results and discussion. The typical age (4-12 months) was observed in 50% of patients only, however, 38% of patients were over 1 year of age, and 20% of children were older than 3 years. All children with Intestinal Intussusception recovered. The complications of Intestinal Intussusception were observed in 7 patients, most of them were admitted to the clinic 24 hours after the onset of the disease. Re-laparotomy was used in three cases; two patients underwent elective (programmed re-laparotomy) and one patient underwent urgent re-laparotomy due to the presence of signs of peritonitis. Recurrent Intussusception was observed in 5 patients; 4 patients developed this condition after conservative disinvagination, one child - after surgery. Conclusions. The complications of Intussusception in children are usually associated with untimely diagnosis and treatment. Diagnostic laparoscopy is a highly informative method of diagnosis in the absence of typical symptoms of Intussusception being also an effective minimally invasive treatment. When selecting the method of Intussusception treatment you should be guided by the duration of rectal bleeding and Doppler data being the most important criteria for determining the degree of the impairment of hemomicrocirculation in the invaginated intestine. Conservative disinvagination is the priority method of treating Intussusception.

A 30-Year Experience in Treatment of Intestinal Intussusception in Children by Own Technique
Galician Medical Journal, 2016Co-Authors: M I Grytsenko, Ye M GrytsenkoAbstract:The issues on objectification and selection of indications for conservative treatment of Intestinal Intussusception in children remain to be disputable.Materials and methods. The experience of treating 249 pediatric patients (172 boys and 77 girls) with Intestinal Intussusception at the age of 2 months - 13 years was analyzed. There were 265 cases of Intestinal Intussusception including 16 cases of the recurrence in 11 children. Conservative treatment was performed in 178 (71.5%) children, 71 (28.5%) children were operated on. To make the analysis, children were divided into 3 groups according to three ten-year periods.Results and discussion. The statistical analysis demonstrated the decrease in the number of patients with the increase in the number of children over 1 year of age over the past decade. The 1st decade was characterized by the introduction and experimental substantiation of flow-through pneumatic insufflation developed by the author with following refusal of X-Ray control. The methods of objectification of the criteria for non-surgical reduction of Intussusception using flow-through pneumatic insufflation were developed experimentally. In the 2nd decade the algorithm for treatment of Intestinal Intussusception was developed; the indications for non-surgical reduction of Intussusception were extended. 5 (22.7%) children out of 22 with disease duration of more than 24 hours and 6 (46.2%) children out of 13 over 1 year of age underwent non-surgical reduction of Intussusception. In the 3rd decade the indications for non-surgical reduction of Intussusception were extended. 11 (57.9%) children out of 19 with disease duration of more than 24 hours and 20 (74.1%) children out of 27 over 1 year of age underwent non-surgical reduction of Intussusception. Only in 4 (28.5%) children out of 14 over 1 year of age who were operated on, we found out anatomical cause of the condition. We have analized the experience in treating 11 children with 16 recurrences of Intestinal Intussusception. In 7 cases non-surgical reduction was performed, 4 children were operated on. During surgeries there were observed no anatomical causes or predispositions to Intussusception. Lethal outcomes were not registered.Conclusions. Thus, flow-through pneumatic insufflation is an effective and objective technique of non-surgical reduction of Intestinal Intussusception in infants. Non-surgical reduction of Intestinal Intussusception can be performed in the majority of patients without the signs of peritonitis. The duration of the condition, age of patients and the presence of recurrence should not be considered as absolute criteria in choosing treatment tactics in Intestinal Intussusception.

protective effects of hydrogen rich water on the Intestinal ischemia reperfusion injury due to Intestinal Intussusception in a rat model
Medical gas research, 2017Co-Authors: Min Chen, Sang Sang, Long-long Hou, Mao-lang TianAbstract:This study aimed to investigate the protective effects of hydrogen rich water on the Intestinal ischemia/reperfusion (I/R) injury in a rat Intestinal Intussusception (II) model. Ninety Sprague-Dawley rats were randomly assigned into three groups (n = 30 per group). In sham group, rats received laparotomy, and the intestine was exposed for 15 minutes without II. In I/R + saline group and I/R + hydrogen group, rats received II after laparotomy and then intestine was relocated 8 hours later, followed by immediately intraperitoneal injection of normal saline and hydrogen rich water (HRW) (5 mL/kg), respectively. One hour later, the intestine was collected for hematoxylin-eosin staining and immunohistochemistry for apoptotic cells and 8-oxo-deoxyguanosine, and blood was harvested for detection of tumor necrosis factor-α, malondialdehyde and superoxide dismutase. Hematoxylin-eosin staining showed the Intestinal mucosa was significantly damaged in I/R + saline group, which was markedly attenuated after HRW treatment. The serum tumor necrosis factor-α content increased significantly in I/R + saline group, but HRW treatment reduced serum tumor necrosis factor-α content as compared to I/R + saline group (P < 0.05). Serum malondialdehyde content and 8-oxo-deoxyguanosine positive cells in the intestine increased dramatically after II, but HRW significantly reduced them in I/R+hydrogen group (P < 0.05). In addition, superoxide dismutase activity reduced markedly and apoptotic cells increased in I/R + saline group as compared to sham group, but they HRW increased superoxide dismutase activity and reduced apoptotic cells significantly in I/R + hydrogen group (P < 0.05). Our results indicate hydrogen rich water is able to attenuate II induced Intestinal I/R injury via inhibiting Intestinal inflammation, attenuating Intestinal/serum oxidative stress and reducing apoptotic Intestinal cells.
