Transanal endoscopic microsurgery (TEM) in the treatment of postoperative colorectal stenosis / Microcirurgia endoscópica transanal (TEM) no tratamento de estenose colorretal pós-operatória

BACKGROUND: Strictures of low colorectal anastomosis are increasing by use the anastomotic stapler. There are many kinds of treatments like dilation, transanal rectotomy, and resection with linear or circular stapler. Other methods includes endoscopic knifes, absorbable sutures and laparotomy. The Transanal Endoscopic Microsurgery (TEM) has been used to treat postoperative anastomotic stenosis. CASES REPORT: Three cases of anastomotic strictures after low colorectal anastomosis were treated with TEM with success in medium follow-up. They had a good postoperative evolution without recurrence of symptoms and stenosis. CONCLUSION: The new TEM surgical approach seems to be a safe choice for the treatment of the postoperative colorectal stenosis.

INTRODUÇÃO: Estenoses de anastomoses colônicas baixas estão sendo mais relatadas devido ao maior uso de anastomoses mecânicas. Existem vários processos de tratamento como dilatações, retotomia transanal e ressecções com re-anastomoses mecânicas. Outros métodos incluem secções endoscópicas, secções com anastomoses com suturas absorvíveis e laparotomia. A Microcirurgia Endoscópica Transanal (TEM) está sendo proposta para o tratamento das estenoses anastomóticas. RELATO DOS CASOS: Três casos de estenoses anastomóticas foram tratados pela TEM com bom resultado em relação ao seguimento a médio prazo sem recurrência de sintomas. CONCLUSÃO: A TEM parece ser boa opção para o tratamento das estenoses resultantes das anastomoses coloretais baixas.

Custo comparado da Microcirurgia Endoscópica Transanal (TEM) com a retossigmoidectomia anterior e com a cirurgia de amputação abdômino-perineal do reto / Comparative cost among Transanal Endoscopic Microsurgery (TEM), anterior resection and Miles procedure

RACIONAL: A Microcirurgia Endoscópica Transanal (TEM) corresponde a um dos mais recentes avanços no tratamento para lesões retais benignas e malignas. OBJETIVO: Determinar o custo da TEM no Hospital de Clínicas da Universidade Federal do Paraná, comparando-o ao da amputação abdômino-perineal do reto e da retossigmoidectomia anterior, estabelecendo parâmetros de custo-efetividade no âmbito do Sistema Único de Saúde. MÉTODOS: Estudo observacional, prospectivo e de coorte da avaliação dos custos dos três procedimentos cirúrgicos citados, enfocando gastos laboratoriais, com medicamentos e internação. Foram incluídos 74 pacientes, 27 submetidos à TEM, 29 à retossigmoidectomia anterior e 18 à amputação abdômino-perineal. RESULTADOS: Com relação à idade, não se observa diferença estatisticamente significativa entre os grupos. O grupo da TEM apresentou o menor tempo de internação (5,51 dias) comparado à retossigmoidectomia anterior (20,41) e à amputação abdômino-perineal (18,33). Quando se consideram os custos laboratoriais, de medicamentos e de diárias hospitalares, observam-se diferenças significantes entre os três procedimentos com custo muito inferior no grupo da TEM, cerca de 2,5 a 4 vezes menor na comparação global (R$ 1.326,71 vs R$ 5.427,16 vs R$ 4.310,20, respectivamente). CONLUSÃO: As vantagens da TEM se mostram evidentes no que tange a custos de internação e permanência hospitalar, com redução significativa quando comparado às técnicas convencionais.

BACKGROUND: Transanal Endoscopic Microsurgery (TEM) corresponds to one of the most recent advances in treating bening and malignant rectal lesions. AIM: To determine the cost of TEM at the Hospital de Clínicas of the Federal University of Paraná, and compare it to the cost of a perineal-abdominal amputation of the rectum and of an anterior rectosigmoidectomy, therefore establishing cost-effective parameters with regards to the "Sistema Único de Saúde”. METHODS: Observational and prospective study pertaining cost evaluation of the three surgical procedures pointed above, focusing on laboratory expenses with drugs and hospitalization. Seventy four patients were included in the study, and of these 27 were submitted to TEM, 29 to anterior rectosigmoidectomy and 18 to perineal-abdominal amputation of the rectum. RESULTS: With regards to age, no significant statistical difference was observed. The group who underwent TEM presented the lowest admission period (5,51 days) when compared to the anterior rectosigmoidectomy (20,41) and to the perineal-abdominal amputation of the rectum (18,33). With regards to laboratory expenses, drug and hospital daily rates, significant statistical differences were observed between the three surgical procedures. The TEM group had the lowest cost, approximately 2.5 to four times smaller in the overall comparison (R$ 1,326.71 vs R$ 5,427.16 vs R$ 4,310.20 respectively). CONCLUSION: TEM advantages are evident through admission and hospital stay costs, with significant reduction when compared to conventional techniques.

[Effect of watery extract of Orbignya phalerata (babassu) in the gastric healing in rats: morphological and tensiometric study]. / Efeito do extrato aquoso de Orbignya phalerata (babaçu) na cicatrização do estômago em ratos: estudo morfológico e tensiométrico.

INTRODUCTION: The large use of plants in the prevention and treatment of different diseases is a milenar practice. In Brazil due to it's rich flora there is a huge material for research and use in popular medicine. The babassu (Orbignya phalerata) is a native tree from North of the Brazil and has a high concentration at the State of Maranhão. The powder of it's mesocarp is known as amid, and has been used as meal and medication due to the known activity against antiinflammatory reaction, pain, pyrexia and immunomodulation. PURPOSE: To analyze the effect of mesocarp of Orbignya phalerata (babassu) in gastric wound healing in rats under morphologic and tensiometric aspects. METHOD: Forty Wistar rats, male, adults were submitted to a longitudinal incision of 1 cm in the gastric body and sutured with separated stitches of polypropylene 6.0. After this common procedure the animals were allocated in the aleatory way in two groups Orbignya (GO) and Control (GC) with 20 animals each one. In the GO was used intraperitoneal doses of 50 mg/kh of Orbignya phalerata extract and in the GC water 1 ml/kg. Each group was divided in two subgroups of ten rats according to the period of death, at 3rd and 7th post-operative days. After the death, the abdominal cavity was evaluated and the stomach withdrawn. For the comparative analysis between the groups the macroscopic and histological parameters of wound healing were utilized. RESULTS: There were no abscess, fistulae and haematom in the animals of the study. Abdominal adhesions were observed in both groups of the animals at 3rd and 7th post-operative days. Dehiscence of the gastrography was identified in one 3rd day rat of subgroups GO. The resistance to air insufflation was higher in GO 3rd day (p=0.087). The analysis of histological parameters showed statistical difference related to wound coaptation in favor to subgroup GO 7th post-operative day. CONCLUSIONS: The extract of mesocarp of Orbignya phalerata in dose and path utilized positively interfered on the gastrography when compared with control group in animals at 7th post-operative day.

INTRODUÇÃO: A utilização de plantas na prevenção e no tratamento de doenças é prática milenar. O babaçu (Orbignya phalerata) é uma palmeira nativa do meio norte do Brasil, tendo sua maior concentração no Estdo do Maranhão. O pó do mesocarpo do coco babaçu é popularmente conhecido como amido e tem sido usado como alimento e como medicamento por apresentar atividade antiinflamatória, imunomoduladora, analgésica e antipirética. OBJETIVO: Avaliar o efeito do extrato aquoso do mesocarpo de Orbignya phalerata na cicatrização do estômago em ratos, sob aspectos morfológico e tensiométrico. MÉTODOS: Quarenta ratos da linhagem Wistar, adultos, machos foram submetidos à incisão longitudinal de 1cm no corpo gástrico e síntese em plano único com pontos separados de polipropilene 6-0. Após este procedimento comum, os animais foram distribuídos aleatoriamente em dois grupos, Orbignya (GO) e Controle (GC), contendo 20 animais cada. No GO utilizou-se dose única intra-peritoneal de extrato aquoso da planta na dose de 50mg/kg e no GC, água destilada, 1ml/kg de peso. Cada grupo foi dividido em dois subgrupos de 10, conforme o dia da morte dos animais, nos 3º e 7º dias do período pós-operatório. Após a morte, foi realizado o inventário da cavidade abdominal e procedeu-se a retirada do estômago, com posterior avaliação tensiométrica e análise miccccroscópica. Na análise comparativa entre os dois grupos utilizou parâmetros macroscópicos e microscópicos da cicatrização. RESULTADOS: Não foram detectados abscessos, fístulas ou hematomas em nenhum animal. Houve aderências abdominais nos animais dos 3º e 7º dias do período pós-operatório nos dois grupos. Houve deiscência da gastrorrafia em um rato do sub-grupo GO morto no 3º dia. A resistência à insuflação de ar atmosférico foi maior no GC de três dias (p=0,087). A análise dos parâmetros histológicos demonstrou diferença estatisticamente significativa apenas quanto à coaptação das bordas, favorecendo o sub-grupo GO de sete dias...(AU)

Jaundice in second intention wound healing in rats

PURPOSE: The objective of the present study was to monitor the process of second intention skin wound healing in rats with jaundice. METHODS: The study was divided into two steps. In the first, obstructive jaundice was induced in 68 male rats to investigate the biochemical changes and to determine the ideal time for the study of healing In the second step, 54 rats were divided into two groups: control (normal) and experimental (jaundiced). Seventy-two hours after jaundice induction, a standardized wound was produced in the dorsum by removing the skin and the subcutaneous net, whose contraction was assessed on the 3rd, 7th, 10th and 14th day and monitored with a computer program. After sacrifice, the tissue was submitted to histopathologic analysis. RESULTS: The most marked biochemical changes were detected between the 3rd and 5th day. The reduction of he wound area was slower in the jaundice group at all 4 time points studied (p3=0.0366, p7=0.0054, p1o=0.0000. p,4=0.0000). Collagen concentration was lower in the wound of jaundiced animals (p3=0.0000. p7 0.0000. pI4 0.0000). CONCLUSION: Jaundice delays collagen deposition and maturation and wound contraction in wounds left to heal by second intention wound healing in rats.
