ABSTRACT
O íleo biliar (IB) é complicação rara da colecistite decorrente de uma comunicação anormal entre a via biliar e o tubo digestivo, a qual permite a migração de um cálculo biliar volumoso para a luz entérica. É responsável por menos de 3% de todos os casos de obstrução intestinal mecânica e apresenta maior incidência em pacientes com mais de 65 anos de idade, representando até 25% dos casos de obstrução intestinal mecânica nestes. Frequentemente cursa com um quadro de obstrução intestinal que, se não tratada a tempo, pode apresentar elevados índices de morbidade e mortalidade. O conhecimento prévio dessa patologia é de grande importância principalmente em atendimentos de urgência e emergência, pois o tratamento é eminentemente cirúrgico e a incidência de diagnóstico pré-operatório é relativamente baixa. O artigo abaixo apresenta o caso de uma paciente de 74 anos, com íleo biliar, que foi cirurgicamente tratada por uma laparotomia exploradora, na qual foi realizada a retirada de cálculo em jejuno (enterotomia). Não foram realizados os procedimentos de colecistectomia e correção de fístula colecistoduodenal em um primeiro momento.
Biliary ileus (IB) is a rare complication of cholecystitis due to an abnormal communication between the biliary tract and the digestive tract which allows the migration of a large gallstone to the enteric light. It accounts for less than 3% of all cases of intestinal obstruction and it has a higher incidence in patients over 65 years of age, representing up to 25% of the cases in this age group. IB if not treated in time, can have high rates of morbidity and mortality. Prior knowledge of this pathology is of great importance, especially in urgent and emergency care because the treatment is mainly surgical and the incidence of preoperative diagnosis is relatively low. The following article presents the case of a patient with 74 years of age with biliary ileus, which was surgically treated by performing a laparotomy, in which removal of calculus was performed in the jejunum through an enterotomy. Nor laparoscopic procedures neither correction of the colecistoduodenal fistula were performed.

Objective To introduce a novel technique of intracolonic shunt procedure used in the anus - preserving operation for acute intestinal obstruction resulted from cancer at low and middle portions of rectum and assess the clinical significance. Methods In total, 81 patients with acute obstruction of low and middle portion of rectum caused by cancer were randomly ( random number) divided into control group and study group. In control group, 42 patients were operated with preventive transverse colonostomy or terminal ileum stoma after low proximal resection of rectum involved in cancer, while 39 patients were operated with intracolonic shunt procedure by using a biodegradable anastomosis ring and a condom placed 5 cm above anastomosis for protection in study group. Results There were no significant differences in sex, age, tumor site, tumor size and the distance from anstomosis to anal-edge between two groups. In both groups, the bowel movement resumed in 2 ~ 5 days after operation (P > 0.05). In study group, the rate of anastomosis leakage was 7.7% (3/39), and leakages were treated with drainage for 7.1 days in average to be healed, and the biodegradable anastomosis ring detached and were discharged in 14 -23 days (17 days in average), and there were no complications of drainage happened. The anastomotic stenosis occurred in three patients (7. 7% ) within 6 months after operation. In control group, 11.9% patients (5/42) had anastomosis leakage and they treated with drainage for 18.2 days in average to get the leakage healed, and 35. 7% patients (15/42) had stoma complications, and anastomotic stenosis happened in 28.6% patients (12/42) within 6 months after operation, and 7. 1% patients need another operation because of severe anastomosis stenosis. There were no significant differences in rate of anastomosis leakage between tow groups ( P > 0. 05), but there were significant differences in drainage days after anstomosis leakage happened and 6 - months anastomosis stenosis between two groups (P<0.05). Conclusions In the anus -preserving operation for acute intestinal obstruction at low and middle portions of rectum caused by cancer , the intracolonic shunt procedure is convenient and safty, and reduces the hazard incurred by anastomosis leakage and anastomosis stenosis compared with classic stoma operation.
ABSTRACT
Objetivo: investigar experimentalmente o suprimento arterial do colo descendente e reto, após ligadura da artéria mesentérica caudal, pela análise da viabilidade da arcada paracólica suprida pela persistência da irrigação do colo descendente. Métodos: foram estudados 30 animais separados em três grupos para observação pós-operatória de 24, 48 e 72 horas. Realizaram-se laparotomia, ligadura da artéria mesentérica caudal e dos vasos retais médios, ligadura do pedículo vascular retal inferior, amputação do reto e posterior colostomia perineal. Foi realizada relaparotomia após o período de observação, com identificação da mesma região. Os cães foram, então, mortos, sendo retirados três pequenos segmentos: um a 10 cm e dois a 10 cm acima e abaixo do linfonodo mesentérico caudal, respectivamente. Resultados: no grupo de animais observados com 72 horas de pós-operatório, abaixo do linfonodo, houve viabilidade estatisticamente significativa, tendo ocorrido necrose estatisticamente significativa nos grupos de 24 e 48 horas. Conclusão: a viabilidade do cólon e do reto cranial depende de anastomose entre os territórios da mesentérica cranial e caudal, mas essa comunicação não está presente em todos os animais.
Objective: experimentally investigate the arterial supply of the descending colon and rectum after ligation of the caudal mesenteric artery, by examining the viability of the paracolic arcade supplied by the persistent irrigation of the descending colon. Methods: 30 animals separated into three groups for 24, 48 and 72 hours posoperatory observation were under study. Laparotomy, ligation of the caudal mesenteric artery and middle rectal vessels, ligation of the inferior rectal vascular pedicle, amputation of lhe rectum and posterior perineal colostomy were performed. Then the dogs were killed, and three small segments were removed: one at 10 cm and two others at 10 cm above and below the caudal mesenteric lymph nodes, respectively. Results: in the group of animals observed with 72 hours posoperatory, there was statistically significant viability below the limph node,with statistically significant necrosis in the 24 and 48 hour groups. Conclusions: the viability of colon and rectal cranial depends on the anastomosis between the territories of the cranial and caudal mesentric, but this communication is not found in all the animals.

Objective To determine the effect and safety of metallic stents in the treatment of acute malignant colorectal obstruction.Methods From May,2000 to June,2003, self-expanding metallic stents were implanted in 15 patients with acute left colonic obstruction caused by malignancies. The postoperative remission and complications were observed.Results Stents were implanted successfully in 12 cases(80.0%,12/15).Of the 12 cases,the obstruction were all disappeared within 24h. No death or colonic perforation happened in this series. Stent migration and anal pain developed each in one case after stent implantation. Elective radical resection was performed on 8 cases after bowel preparation and supportive therapy; and stents reserved permanently in other 4 cases. Conclusions The implantation of self-expanding metallic stents is a safe and effective method for the temporary remission or permanent treatment of acute left-colonic or rectal obstruction caused by malignancies,it can instead of colostomy.
