P0745 ENDOSCOPIC DIAGNOSIS AND TREATMENT OF INTUSSUSCEPTION IN CHILDREN UNDER 2 YEARS
Bibliographic record
Abstract
Introduction: The non-operative treatment of intussusceptions doesn’t enable to evaluate completely injury degree of intussuscepted intestine and determine possible etiopathogenic factors. This study describes endoscopic treatment of intussusceptions and gives more deep understanding of the factors contributing to it. Methods: 73 colonoscopies were performed under general anesthesia in children from 5 to 14 months of age, between 1985 and 2001. All patients were divided in 4 groups depending on the length and severity of illness. I group – 8 patients (10,9%) were admitted in 6 hours after disease onset, II group – 26 patients (35,6%) in 12 hours, III group – 27 patients (37%) in 24 hours, IV group – 12 patients (35,6) in 30 hours. For the majority of patients illness was advanced because of intestinal dyspepsia on a background of adenoviral, rotaviral infection or diet disturbances. There were performed endoscopic pneumatic reductions after visual assessment of intussuscepted bowel. Results: In the I group colonoscopy desinvagination was done in 8 (100%) patients, in the II group – 26 (100%) cases, in the III group – 25 (92,6%) and in the IV group – 9 (75%) cases. Endoscopic treatment was done totally in 68 from 73 (93,1%) cases. The valve of Baugin and 10–15 cm in length terminal ileum were observed usually after endoscopic pneumatic reduction. Flat-form, malclosed, slit-like, immature valve of Baugin with hemorrhages was visualized in all cases. There was condition of inflammation in distal ileum, with hypertrophic lymphoid follicles, that were distributed in high density fashion (III degree by K. Nagasako, T. Takemoto, 1973, S. Doletski at all 1985). The ileitis was affirmed morphologically. Conclusion: The role of rotavirus, adenovirus or reovirus with hyperplasia of lymph nodes and Peyer’s patches, as single causes of intussusceptin are well known. Also, lymph nodes hyperplasia is common in childhood, as well as viral enteritis have much more patients than intussusception. But viral infections may cause progression of lymph nodes hyperplasia which reduces the lumen of ileum and becomes the centre of intestinal infringement. On the basis of our investigations we made suppose, that the viral infections in conjunction with functional immaturity of Baugin’s valve, with III degree hyperplasia of lymphoid follicles in terminal ileum may be important etiologic factors for intussusception in childhood.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
