Ileosigmoid Knot: A Rare Cause of Intestinal Obstruction.

Ileosigmoid knotting also known as compound volvulus or double volvulus is a rare cause of intestinal obstruction. Here, we present a case of acute intestinal obstruction in shock. The patient was resuscitated taken up for an emergency exploratory laparotomy, which revealed a large volume of hemorrhagic fluid and dilated gangrenous loops of ileum and sigmoid. A loop of ileum had encircled the base of sigmoid to form a knot resulting in gangrene of both the ileum and the sigmoid colon. Resection of gangrenous ileum and sigmoid colon with ileo-ileal and colorectal anastomosis with a temporary diversion colostomy was done.

Estudo retrospectivo das itussuscepções em cães / Retrospective study of canine intussusception

Intussuscepção é uma causa comum de obstruções intestinais em pequenos animais. No presente estudo foram analisados, retrospectivamente, prontuários de 97 cães com diagnóstico de intussuscepção intestinal no período de Janeiro de 2000 a Julho de 2007. Foram avaliados dados referentes a raça, idade e sexo do animal, sintomas clínicos, meios de diagnóstico, tratamento e evolução do quadro. Animais com idade inferior a um ano apresentaram maior ocorrência. Diversos fatores foram relacionados como predisponentes, sendo a intoxicação prévia por carbamatos presente em 13 cães. A porção mais acometida foi a junção ileo-cólica e a enterectomia e enteroanastomose foram realizadas em 71% dos animais. Apenas três animais, não submetidos a enterectomia no primeiro procedimento, apresentaram recidiva do quadro. Três animais foram a óbito após a intervenção cirúrgica. O número expressivo de casos analisados associado à ausência de dados regionais até então existentes contribuiu para o conhecimento da afecção e de seu tratamento

Intussusception is a common cause of bowel obstruction in small animals. In this study, 97 records of dogs with diagnosis of intestinal intussusceptions between the period of January/2000 and July/2007 were retrospectively reviewed. Analyzed data included symptoms, predisposing factors, means of diagnosis, treatment and evolution. Animals with less than one year showed more occurrences. Many findings could be related to predisposing factor, where previous intoxications with carbamates showed to be the most important (13dogs). The most affected portion by intussusceptions was the ileum-colic junction and enterectomy was necessary in 71% of the animals. Only three animals, not submitted to enterectomy in the first procedure, showed recurrence of intussusception. Three animals came to death after surgery. The expressive number of analyzed cases allied to absence of regional data contributed to the knowledge of the disease and its treatment.

Intussusception in southern Indian children: lack of association with diarrheal disease and oral polio vaccine immunization.

BACKGROUND: Intussusception is the most common cause of intestinal obstruction in young children and has been reported as a complication of a recently withdrawn tetravalent reassortant rotavirus vaccine. METHODS: We studied the history, clinical presentation, management and outcome of intussusception presenting to a tertiary care hospital in southern India over a 10-year period, in order to assess potential association with diarrheal disease and immunization. RESULTS: Data from 137 index cases and 280 control subjects indicated that the risk of diarrheal disease or oral polio vaccine administration in the month prior to presentation was similar in the index cases and controls. Mean time to presentation to hospital after developing symptoms was 1.8 days, and 77.3% of patients required surgery, with 47.4% undergoing intestinal resection. Mortality was 0.006%. CONCLUSIONS: No association could be demonstrated between gastroenteritis or oral poliovirus vaccine immunization and intussusception in southern Indian children. These children presented later and required operative intervention more frequently than has been reported in other studies, but had a good outcome with low mortality.
