Multiple portions enteral nutrition and chyme reinfusion of a blunt bowel injury patient with hyperbilirubinemia undergoing open abdomen: A case report / 中华创伤杂志(英文版)

Blunt bowel injury (BBI) is relatively rare but life-threatening when delayed in surgical repair or anastomosis. Providing enteral nutrition (EN) in BBI patients with open abdomen after damage control surgery is challenging, especially for those with discontinuity of the bowel. Here, we report a 47-year-old male driver who was involved in a motor vehicle collision and developed ascites on post-trauma day 3. Emergency exploratory laparotomy at a local hospital revealed a complete rupture of the jejunum and then primary anastomosis was performed. Postoperatively, the patient was transferred to our trauma center for septic shock and hyperbilirubinemia. Following salvage resuscitation, damage control laparotomy with open abdomen was performed for abdominal sepsis, and a temporary double enterostomy (TDE) was created where the anastomosis was ruptured. Given the TDE and high risk of malnutrition, multiple portions EN were performed, including a proximal portion EN support through a nasogastric tube and a distal portion EN via a jejunal feeding tube. Besides, chyme delivered from the proximal portion of TDE was injected into the distal portion of TDE via a jejunal feeding tube. Hyperbilirubinemia was alleviated with the increase in chyme reinfusion. After 6 months of home EN and chyme reinfusion, the patient finally underwent TDE reversal and abdominal wall reconstruction and was discharged with a regular diet. For BBI patients with postoperative hyperbilirubinemia who underwent open abdomen, the combination of multiple portions EN and chyme reinfusion may be a feasible and safe option.

Reconstrucción poscirugía de Hartmann / Stoma reversal after the Hartmann's procedure

RESUMEN Antecedentes: la reconstrucciónn del tránsito intestinal luego de una operación de Hartmann es un procedimiento habitualmente complejo y con alta morbilidad. Objetivo: analizar la tasa de reconstrucción después de la cirugía de Hartmann y resultados posoperatorios en nuestra experiencia. Material y métodos: análisis retrospectivo de pacientes a los que se les practicó la reconstrucción del tránsito intestinal posterior a una cirugía de Hartmann en un período 16 años. Revisamos la bibliografía y nuestra base de datos. Luego traspasamos la información disponible a una grilla de datos construida con variables habitualmente analizadas en la literatura. Finalmente, analizamos los resultados mediante medidas básicas de tendencia central. Resultados: en 16 años realizamos 92 operaciones de Hartmann, de las cuales 69 (75%) llegaron a la reconstrucción. Edad promedio: 58 años. El 52% de los pacientes fueron hombres. La operación de Hartmann fue de urgencia en el 48% y 58% resultaron malignas. Tiempo transcurrido hasta la reconstrucción: en promedio, 9 meses, y el 90% (N 62) de los casos se realizó por vía laparoscópica. Morbilidad general 38% y ajustada a los grados III y IV de Clavien-Dindo fue 11,5%. No hubo mortalidad. Conclusión: los resultados obtenidos son semejantes a los publicados y nuestra experiencia nos motiva a continuar eligiendo el abordaje laparoscópico.

ABSTRACT Background: Background: Stoma reversal after Hartman's operation is usually a complex procedure and is associated high morbidity. Objective: To analyze the rate of reversal after the Hartmann's procedure and the postoperative outcomes in our experience. Material and methods: We conducted a retrospective analysis of patients undergoing reversal after the Hartmann's procedure over a 16-year period with review of the literature and of our database and transferred the available information to a data grid constructed with variables commonly analyzed in the literature. Finally, we analyzed the results using basic measures of central tendency. Results: Over a 16-year period, we performed 92 Hartmann's operations; 69 (75%) reached the reversal stage. Mean age was 58 years and 52% were men. Forty-eight percent of the Hartmann's procedures were emergency surgeries and 58% were due to cancer. Mean time to reversal was 9 months and 90% (n = 62) were laparoscopic procedures. Overall morbidity and adjusted for complications grade III and IV of the Clavien-Dindo classification were 38% and 11.5%, respectively. None of the patients died. Conclusion: The results obtained are similar to those published and our experience motivates us to continue choosing the laparoscopic approach.

Progress in intestinal adaptation after enterectomy / 中华胃肠外科杂志

Intestinal adaptation is a spontaneous compensation of the remanent bowel after extensive enterectomy, which improves the absorption capacity of the remanent bowel to energy, fluid and other nutrients. Intestinal adaptation mainly occurs within 2 years after enterectomy, including morphological changes, hyperfunction and hyperphagia. Intestinal adaptation is the key factor for patients with short bowel syndrome to weaning off parenteral nutrition dependence and mainly influenced by length of remanent bowel, type of surgery and colon continuity. In addition, multiple factors including enteral feeding, glucagon-like peptide 2 (GLP-2), growth hormone, gut microbiota and its metabolites regulate intestinal adaptation via multi-biological pathways, such as proliferation and differentiation of stem cell, apoptosis, angiogenesis, nutrients transport related protein expression, gut endocrine etc. Phase III clinical trials have verified the safety and efficacy of teduglutide (long-acting GLP-2) and somatropin (recombinant human growth hormone) in improving intestinal adaptation, and both have been approved for clinical use. We aim to review the current knowledge about characteristics, mechanism, evaluation methods, key factors, clinical strategies of intestinal adaptation.

The elaboration process of an educational guide for individuals with an ostomy: development of educational guidelines for the self-care of patients with an intestinal and/or urinary ostomy / Processo de elaboração de guia educacional para estomizados: construção de guia educativo para o autocuidado de pessoas com estoma intestinal e/ou urinário

This study aimed to develop a guideline concerning the care directed toward an individual with an intestinal and/or urinary ostomy attending the Assistance Service for Ostomized Patients implemented at the Clinical Hospital of Uberlândia UFU, in order that such individuals be provided the means of self-care and thus improve their life quality. A bibliographical survey was performed on the theme, which focused on Guidelines Based on Evidence. The development of these guidelines was based on a bibliographical survey and took as its foundation the principles of Orem's self-care theory and the educational practices applied to pedagogy in health according to Paulo Freire's philosophy concerning liberating education, qualification and dialogue between the subject and the professional, which grants the possibility of aiding the family and patient to modify their lifestyles and be the agents of transformation, thus favoring the development of their autonomy. The printed educational material brings new information and knowledge to the ostomized patient.

Trata-se da elaboração de um guia de orientação sobre os cuidados com a pessoa com estoma intestinal e/ou urinária acolhida em um Serviço de Atenção à Pessoa Estomizada, para instrumentalizá-la para o autocuidado e favorecer melhorias em sua qualidade de vida. Realizado por meio de levantamento bibliográfico sobre a temática com foco nas Diretrizes Baseadas em Evidências. A elaboração ocorreu por meio da associação do levantamento bibliográfico e teve por base referencial os princípios da teoria de Orem sobre o autocuidado e das práticas educativas aplicadas à pedagogia da saúde com base nos ensinamentos freirianos sobre a educação libertadora, a qualificação e o diálogo entre o sujeito e o profissional, como subsídio à possibilidade de auxiliar família e paciente a modificarem seu estilo de vida e serem agentes de transformação, privilegiando o desenvolvimento da sua autonomia.

Effect of supplementation with probiotics on colonic anastomoses in rats: morphological and tensiometric study / Efeito da suplementação com probióticos em anastomoses colônicas de ratos: estudo morfológico e tensiométrico

ABSTRACT Background: The use of probiotics positively modifies the composition and function of intestinal flora, improving the quality of intestinal anastomosis. Aim: To evaluate the impact of probiotic use on intestinal anastomosis of rats. Method: Thirty-six adult male Wistar rats (Rattus norvegicus albinus, Rodentia Mammalia) were used, with body weight ranging from 220-320 g. The animals were housed and acclimated individually in boxes receiving water and ration ad libitum. After initial acclimatization, the control group received perioperative ration ad libitum for 12 days (seven preoperatively and five postoperatively) associated with the maltodextrin formula at a dose of 250 mg/day in isocaloric and isovolumetric form. Likewise, the probiotic group received oral supplementation of probiotics dose of 250 mg/day, associated with isocaloric and isovolumetric diet. The probiotic chosen for this study was composed of strains (doses 1x109 CFU/g)12 Lactobacillus paracasei LPC-37, Bifidobacterium lactis HN0019, Lactobacillus rhamnosus HN001 and Lactobacillus acidophilus NCFM. Probiotics or placebo were administered orally with the aid of a dosimeter spatula. Both groups underwent two colostomies, one in the right colon and the second in rectosigmoid, followed by reanastomosis with eight separate 6-0 mononylon stitches. The sacrifice took place on the fifth day. The parameters evaluated included tensile strength, histology and collagen densitometry. Results: The rate of intestinal fistula for the control and probiotic groups were, respectively, 22.22% and 11.11% (p=0.6581).Perioperative supplementation with probiotics increased collagen deposition of types I and III (p<0.0001), improved maximum traction force and maximum rupture force, p=0.0250 and p=0.0116 respectively, fibrosis area (p<0.0001), and area of the inflammatory infiltrate (p=0.0115). Conclusions: The use of probiotics had a positive impact on the quality of intestinal anastomosis.

RESUMO Racional: A utilização de probióticos modifica positivamente a composição e função da flora intestinal melhorando a qualidade da anastomose intestinal. Objetivo: Avaliar o impacto da utilização de probióticos na anastomose intestinal de ratos. Método: Foram utilizados 36 ratos Wistar (Rattus norvegicus albinus, Rodentia Mammalia), machos adultos, com peso corporal variando entre 220 e 320 g. Os animais foram alojados e aclimatados individualmente em caixas recebendo água e ração ad libitum. Após aclimatação inicial, o grupo controle recebeu perioperatoriamente ração ad libitum por 12 dias (sete no pré-operatório e cinco no pós-operatório) associado à fórmula de maltodextrina na dose de 250 mg/dia de forma isocalórica e isovolumétrica. Na semana que precedeu o procedimento cirúrgico (período de sete dias) e no pós-operatório (por cinco dias), os ratos do grupo estudo receberam suplementação via oral de probióticos dose de 250 mg/dia, associado à dieta isocalórica e isovolumétrica. O probiótico utilizado era composto pelas cepas (doses 1x109 UFC/g)12 Lactobacillus paracasei LPC-37, Bifidobacterium lactis HN0019, Lactobacillus rhamnosus HN001 e Lactobacillus acidophilus NCFM. A administração de probiótico ou placebo foi realizada via oral, com auxílio de espátula com dosímetro. Os dois grupos foram submetidos à duas colostomias, uma em cólon direito e outra em retossigmóide, seguido de reanastomose com oito pontos separados de mononylon 6-0. O sacrifício ocorreu no quinto dia. Os parâmetros avaliados incluíram força tênsil, histologia e densitometria do colágeno. Resultados: A taxa de fístula intestinal para os grupos controle e probiótico foram, respectivamente, 22,22% e 11,11% (p=0.6581). A suplementação peroperatória com probióticos aumentou a deposição de colágeno dos tipos I e III (p<0.0001), melhorou a força máxima de tração e força máxima de ruptura, p=0,0250 e p= 0,0116 respectivamente, área de fibrose (p<0.0001), e área do infiltrado inflamatório (p=0.0115). Conclusões: A utilização de probióticos impactou positivamente na qualidade da anastomose intestinal.

New training model using chickens intestine for pediatric intestinal anastomosis

Abstract Purpose: To develop a new low-cost, easy-to-make and available training model using chickens' intestine for infant intestinal anastomosis. Methods: Segments of chicken intestine were used to create an intestinal anastomosis simulator. We tried to perform an end-to-end, end-to-side and side-to-side anastomosis. Handsewn sutured anastomosis were performed in single layered with interrupted prolene 5-0 suture. The parameters analyzed were cost, intestine's diameter and length, anastomosis patency and flow-through and leakage amount. Results: In all cases it was possible to make the anastomosis in double layered without difficulties, different from the usual ones. There was a positive patency at all anastomoses after the end of the procedure, with no need for reinterventions. Conclusion: The new training model using chickens' intestine for infant intestinal anastomosis is low-cost, easy-to-make and easy available.

Are there differences in the growth adaptation processes of growing and mature organism models of short bowel syndrome?

OBJECTIVES: The purpose of this study was to present an experimental model of short bowel syndrome (SBS) in weaning rats and to compare the adaptative mechanisms of the remaining bowel in weaning rats and adult animals by means of morphometric, histologic and molecular methods. METHODS: Twenty-four weaning rats were divided into 3 groups of 8 animals, one control group and two short bowel groups (euthanasia after 4 and 21 days), and were compared with similar adult groups. Morphometric evaluations of the animals and histopathological and molecular studies of the remaining bowel were performed. RESULTS: The weight of young rats increased after enterectomy, whereas that of adult rats decreased after enterectomy (p<0.0001). The ratio of intestinal length/body weight was significantly higher in weaning rats than in adults (p<0.002), showing that intestinal growth was more intense in weaning rats. Intestinal resection promoted increased thickness of the small bowel lamina propria (p=0.001) and reduced thickness of the colon lamina propria (p=0.04) in weaning rats relative to those in adults. In addition, intestinal resection promoted increased expression of the Bcl-xl gene (antiapoptotic) in adult animals compared with that in weaning rats (p=0.001). CONCLUSION: Morphometric, histological and molecular differences were shown in the adaptation processes of growing and mature organisms.

Insuficiencia intestinal secundaria a síndrome de intestino corto: resultados de un programa multidisciplinario de rehabilitación intestinal / Intestinal failure due to short bowel syndrome: impact of a multidisciplinary intestinal rehabilitation program

Background: In patients suffering intestinal failure due to short bowel, the goal of an Intestinal Rehabilitation Program is to optimize and tailor all aspects of clinical management, and eventually, wean patients off lifelong parenteral nutrition. Aim: To report the results of our program in patients suffering intestinal failure. Patients and Methods: A registry of all patients referred to the Intestinal Failure unit between January 2009 and December 2015 was constructed. Initial work up included prior intestinal surgery, blood tests, endoscopic and imaging studies. Also demographic data, medical and surgical management as well as clinical follow-up, were registered. Results: Data from 14 consecutive patients aged 26 to 84 years (13 women) was reviewed. Mean length of remnant small bowel was 100 cm and they were on parenteral nutrition for a median of eight months. Seven of 14 patients had short bowel secondary to mesenteric vascular events (embolism/thrombosis). Medical management and autologous reconstruction of the bowel included jejuno-colic anastomosis in six, enterorraphies in three, entero-rectal anastomosis in two, lengthening procedures in two, ileo-colic anastomosis in one and reversal Roux-Y gastric bypass in one. Thirteen of 14 patients were weaned off parenteral nutrition. Conclusions: Our Multidisciplinary Intestinal Rehabilitation Program, allowed weaning most of the studied patients off parenteral nutrition.

Evaluation of the effects of ischemic preconditioning on the hematological parameters of rats subjected to intestinal ischemia and reperfusion

OBJECTIVES: Intestinal ischemia/reperfusion often leads to acute lung injury and multiple organ failure. Ischemic preconditioning is protective in nature and reduces tissue injuries in animal and human models. Although hematimetric parameters are widely used as diagnostic tools, there is no report of the influence of intestinal ischemia/reperfusion and ischemic preconditioning on such parameters. We evaluated the hematological changes during ischemia/reperfusion and preconditioning in rats. METHODS: Forty healthy rats were divided into four groups: control, laparotomy, intestinal ischemia/reperfusion and ischemic preconditioning. The intestinal ischemia/reperfusion group received 45 min of superior mesenteric artery occlusion, while the ischemic preconditioning group received 10 min of short ischemia and reperfusion before 45 min of prolonged occlusion. A cell counter was used to analyze blood obtained from rats before and after the surgical procedures and the hematological results were compared among the groups. RESULTS: The results showed significant differences in hematimetric parameters among the groups. The parameters that showed significant differences included lymphocyte, white blood cells and granulocyte counts; hematocrit; mean corpuscular hemoglobin concentration; red cell deviation width; platelet count; mean platelet volume; plateletcrit and platelet distribution width. CONCLUSION: The most remarkable parameters were those related to leukocytes and platelets. Some of the data, including the lymphocyte and granulocytes counts, suggest that ischemic preconditioning attenuates the effect of intestinal ischemia/reperfusion on circulating blood cells. Our work contributes to a better understanding of the hematological responses after intestinal ischemia/reperfusion and IPC, and the present findings may also be used as predictive values. .

Retrospective analysis of patients undergoing bowel transit reconstruction in a tertiary referral hospital of São Paulo's east side / Análise retrospectiva dos pacientes submetidos à reconstrução de trânsito intestinal em hospital terciário de referência da zona leste de São Paulo

Introduction: The morbidity and mortality of patients undergoing bowel transit reconstruction reach significant values. Perhaps this and other factors could explain why 30-60% of patients end up with definitive ostomies, even those with initially temporary ostomies, due to the procedure risks. Objective: To analyze retrospectively the medical records of patients undergoing bowel transit reconstruction in one of the SUS referral hospitals in São Paulo from October 2008 to December 2011. Results: The mean age of our patients was 53.9 years and 54% of those 100 patients studied between October 2008 and December 2011 had significant comorbidity. The indication for creating an initial ostomy was malignancy in 43%, and the mean stoma duration 14.3 months. The mortality rate was 6%. Conclusion: Although the bowel transit reconstruction is a procedure quite desired by patients, its indication should be carefully evaluated, with an appropriate consent from the patient. .

Introdução: A morbi-mortalidade de pacientes submetidos à reconstrução de trânsito intestinal alcança valores significativos e, por esse e outros fatores, talvez se explique o fato que de 30 a 60% dos portadores de ostomia intestinal terminal passam a possuí-la de maneira definitiva, apesar de, na maior parte das vezes, ela ser realizada como procedimento provisório com o argumento de maior segurança do paciente. Objetivo: Analisar retrospectivamente os dados de prontuário de pacientes submetidos à reconstrução de trânsito intestinal em um dos hospitais de referência do SUS na cidade de São Paulo no período de outubro de 2008 a dezembro de 2011. Resultados: A média de idade dos pacientes foi de 53,9 anos e 54% dos 100 pacientes estudados no período de outubro de 2008 e dezembro de 2011 padeciam de alguma comorbidade. A indicação para confecção da ostomia inicial decorreu de doença maligna em 43% e o tempo médio de permanência com o estoma foi de 14,3 meses. A taxa de mortalidade foi de 6%. Conclusão: Embora a reconstrução do trânsito intestinal seja um procedimento bastante desejado pelos pacientes, sua indicação deve ser bastante criteriosa, com consentimento adequado por parte do paciente.

Cloacal Exstrophy: a complex disease

Introduction Cloacal exstrophy is a rare occurrence with an incidence of 1:200,000 to 1:400,000 live births. It represents one of the most challenging reconstructive endeavors faced by pediatric surgeons and urologists. Aside from the genitourinary defects, there are other associated anomalies of the gastrointestinal, musculoskeletal and neurological systems that require a multidisciplinary approach when counseling anxious parents. Material and Methods We present a video of a patient with cloacal exstrophy treated with 21 days of life. Surgery consisted of separation and tubularization of the cecal plate from the exstrophied bladder halves and colostomy construction. The bladder was closed primarily and umbilical scar reconstructed and used for ureteral and cistostomy drainage. A urethral catheter was used to guide bladder neck tubularization. A final epispadic penis was obtained and planned for further repair in a second step. Results The patient had an initial uneventful postoperative course and immediate outcome was excellent. The bladder healed nicely but patient presented with abdominal distension in the 5th day of postoperative setting requiring parenteral nutrition. The distal colon persisted with lower diameter although non obstructive, but causing difficulty for fecal progression. Continuous colostomy dilatation and irrigation were required. Conclusions Approximating the bladder halves in the midline at birth and primary bladder closure is a viable option, intestinal transit may be a issue of concern in the early postoperative follow-up. .

Estudo comparativo entre os fios de algodão, poliglactina e poliglecaprone nas anastomoses intestinais de cães / Comparative study of cotton, polyglactin and polyglecaprone sutures in intestinal anastomoses in dogs

RACIONAL: Nos últimos anos muitos fios de sutura foram desenvolvidos e depois abandonados. Até hoje não foi encontrado um fio cirúrgico ideal aos intestinos ou a outros tecidos de um modo geral, tornando sua escolha tarefa difícil. OBJETIVO: Avaliar macro e microscopicamente a cicatrização de anastomoses do intestino delgado de cães, utilizando suturas com fios de poliglecaprone 25; poliglactina 910 e algodão. MÉTODOS: Vinte cães machos adultos foram operados e submetidos a três anastomoses no intestino delgado empregando a técnica extramucosa com pontos separados. Foram utilizados os três tipos fios e as anastomoses foram analisadas em diferentes períodos no pós-operatório: grupo I -três dias; grupo II - sete dias; grupo III - 14 dias; grupo IV - 21dias. A análise macroscópica consistiu em avaliar a presença ou não de peritonite, aspecto das anastomoses e aderências. Os estudos histológicos das anastomoses, empregando a hematoxilina e eosina e o tricrômico de Masson analisaram a inflamação exsudativa, inflamação granulomatosa, o revestimento epitelial da mucosa e as fibras colágenas. RESULTADOS: Na avaliação macroscópica os fios apresentaram boa coaptação das bordas com moderado grau de aderência entre alças e omento do 3º ao 21º dia do pós-operatório. A avaliação microscópica mostrou inflamação exsudativa com neutrófilos e fibrina que variou de discreta a moderada até o 14º dia; inflamação granulomatosa com presença de macrófagos, células gigantes multinucleadas e células epitelioides mais evidentes ao 14º dia para o fio algodão; presença de tecido de granulação (fibroblastos) e fibras colágenas, de forma moderada, a partir do 7º dia para os três fios. CONCLUSÃO: Os três tipos de fios de sutura apresentaram comportamento semelhante, com boa cicatrização e podem ser recomendados em anastomoses do intestino delgado.

BACKGROUND: Over the years, many sutures were developed and then abandoned. Until now was not found an ideal suture to the intestinal tract or other tissues in general, making the choice a difficult task. AIM: To evaluate, macroscopically and microscopically, the healing process of intestinal anastomoses in dogs using polyglecaprone 25, polyglactin 910 and cotton sutures. METHODS: Twenty adult male dogs were operated on and underwent to three small bowel anastomosis using the technique with submucosal sutures. Were used three threads and the anastomoses were evaluated at different postoperative periods - group I - three days; group II - seven days; group III - 14 days and group IV - 21days. Macroscopic analysis was to assess the presence or absence of peritonitis, aspect of the anastomosis and adhesions. Histological studies of the anastomoses, using hematoxylin and eosin and Masson's trichrome analyzed the exudative inflammation, granulomatous inflammation, the mucosal epithelial coating and collagen fibers. RESULTS: The macroscopic analysis showed good coaptation of the edges with a moderate degree of adhesion between the intestines and omentum three to 21 days after surgery. The microscopic evaluation revealed exudative inflammation with neutrophils and fibrin, which ranged from mild to moderate until the 14th day; granulomatous inflammation with macrophages, multinucleated giant cells and epithelioid cells were more evident at 14th day for the cotton, presence of granulation tissue (fibroblasts) and collagen fibers, a moderate way, from the 7th for the three threads. CONCLUSION: All three threads showed similar behavior and thus they can be indicated for anastomoses of the small intestine.

Severe ischemic bowel necrosis caused by terlipressin during treatment of hepatorenal syndrome

Terlipressin is a vasopressin analogue that is widely used in the treatment of hepatorenal syndrome or variceal bleeding. Because it acts mainly on splanchnic vessels, terlipressin has a lower incidence of severe ischemic complications than does vasopressin. However, it can still lead to serious complications such as myocardial infarction, skin necrosis, or bowel ischemia. Herein we report a case of severe ischemic bowel necrosis in a 46-year-old cirrhotic patient treated with terlipressin. Although the patient received bowel resection, death occurred due to ongoing hypotension and metabolic acidosis. Attention should be paid to patients complaining of abdominal pain during treatment with terlipressin.

Anastomosis terminal funcional con sutura mecánica en cirugía intestinal: resultados precoces de una serie prospectiva / Experience with mechanical anastomoses in bowel surgery

Background: The use of mechanical anastomoses reduce the length of gastrointestinal surgical procedures. Aim: To report the experience with mechanical functional terminal anastomoses in bowel surgery. Material and Methods: Prospective non randomized registry of all mechanical anastomoses carried out in a surgical service. Results: A total of 327 patients (193 women) were analyzed. Two hundred and one anastomoses were ileo-colonic and 126 were entero-enteral. Seventeen percent of patients experienced some complication. Fourteen required a new operation due to peritonitis or deep infection of the surgical site. The global rate of anastomotic dehiscence was 3.1 percent. No differences in the rate of complications between surgeons with experience and trainees were observed. Conclusions: Mechanical anastomoses in bowel surgery are safe and require a short learning period to be used.

Se presenta nuestra experiencia con la anastomosis terminal funcional con sutura mecánica en cirugía intestinal. La serie corresponde a 327 pacientes, un 59 por ciento de género femenino. Del total de anastomosis 201 fueron íleo colónicas y 126 entero enterales. El instrumento de sutura más utilizado fue de 75 u 80 mm de longitud y no se registran incidentes durante la confección de la anastomosis. La morbilidad específica se encuentra en el 17 por ciento de la serie, sin diferencias entre los dos tipos de anastomosis. Catorce paciente fueron reoperados por peritonitis o infección profunda del sitio quirúrgico La tasa global de dehiscencia anastomó-tica fue de un 3,1 por ciento ( 5 y 4 casos respectivamente) sin alcanzar significación estadística. Al comparar si la anastomosis fue realizada por un cirujano con experiencia o en formación, tampoco se encontraron diferencias estadísticamente significativas, por lo que nos parece una técnica segura y con una corta curva de aprendizaje.

Complication related to colostomy orifice: intestinal evisceration

Intestinal evisceration at the site of a stoma is a rare event, with high morbimortality. Its clinical manifestation often occurs between the sixth and seventh days after surgery. The risk factors most frequently related to evisceration are: increased intra-abdominal pressure, digestive tract cancer surgery, emergency surgery and stomas in the surgical incision. The authors report the case of a male patient, aged 62, suffering from adenocarcinoma of the rectum with obstructive acute abdomen, who underwent loop transversotomy for decompression. On the fourth day after surgery, he had a bronchospasm crisis, with evisceration of ileum and colon through the colostomic hole. The association of some triggering factors, such as emergency surgery, colorectal malignant neoplasm, increased intra-abdominal pressure and technical failure of colostomy were decisive in the development of this rare peri-colostomy complication.

A evisceração intestinal desenvolvida no sítio de um estoma é um evento raro, tendo elevada morbimortalidade. Sua manifestação clínica ocorre frequentemente entre o sexto e o sétimo dias de pós-operatório. Os fatores de risco mais frequentemente relacionados à evisceração são: aumento da pressão intra-abdominal, câncer do aparelho digestório, cirurgia de urgência e estomias na incisão cirúrgica. Os autores relatam o caso de um paciente do sexo masculino, com 62 anos, portador de adenocarcinoma do reto médio com abdômen agudo obstrutivo, sendo submetido à transversostomia em alça, com finalidade descompressiva. No quarto dia de pós-operatório com crise de broncoespasmo, apresentou evisceração do cólon e íleo pelo orifício abdominal colostômico. A associação de alguns fatores desencadeantes, como a cirurgia de urgência, a doença neoplásica colorretal maligna, o aumento da pressão intra-abdominal e a falha técnica na confecção da colostomia, foram determinantes para o desenvolvimento desta rara complicação pericolostômica.

Anastomosis primaria en enterocolitis necrotizante / Primary anastomosis in necrotizing enterocolitis

Introduction: Necrotizing Enterocolitis (NE) is the most frequent gastrointestinal emergency among newborns (NB). Thirty percent of them require surgical treatment, with resection of the damaged intestinal segment and stoma formation. In some cases, primary resection and anastomosis can be considered. Objective: To review the use of primary anastomosis on NE in 2 pediatric centers, one public hospital and one private clinic. Patients and Method: A retrospective, descriptive study of all NB with NE managed with primary anastomosis at Hospital Exequiel González Cortés y Clínica Las Condes between December 2004 and december 2009. The population was divided into Group A: Unifocal, and Group B: Multifocal intestinal involvement. The following variables were evaluated and compared: gestational age, weight, use of peritoneal drains, characteristics of the resected segment, number of anastomoses, requirement of parenteral nutrition, postoperatory complications. Results: Sixty NB were surgically repaired with primary anastomosis. 12 percent presented birth weight <1.000grams, 22 percent between 1000-1500 grams. In 18 patients 2 anastomoses were performed in different intestinal segments. Postoperatory complications included wound infection in 3 cases and dehiscence of the anastomosis in 1 case. 7 percent evolved with short loop syndrome. Mortality was 11,6 percent, secondary to sepsis. Conclusions: In this experience, Primary Anastomosis in NE appears to be a safe option, with low morbimortality despite the age, weight, IP contamination or extension of the disease.

Introducción: Enterocolitis Necrotizante (ECN) es la emergencia gastrointestinal más común del recién nacido (RN), 30 por ciento requiere tratamiento quirúrgico, con resección del segmento intestinal dañado, realizando luego una ostomía en la mayoría. En recientes casos la resección intestinal y anastomosis primaria han sido reportados en forma exitosa. Objetivo: Evaluar la experiencia del manejo con anastomosis primaria en ECN en 2 centros pediátricos, un Hospital público y una Clínica privada. Pacientes y Método: Estudio descriptivo retrospectivo. Se incluyó a RN del Hospital Exequiel González Cortés y Clínica Las Condes con ECN manejados con anastomosis primaria, entre diciembre de 2004 y diciembre de 2009. Se dividieron en Grupo A: Unifocal; Grupo B: Compromiso intestinal multifocal. Se comparó entre ambos grupos: edad gestacional, peso, utilización de drenajes peritoneales, características del segmento resecado, número de anastomosis, requerimientos de nutrición parenteral, complicaciones postoperatorias. Resultados: Se sometió a cirugía con anastomosis primaria a 60 recién nacidos. El peso de nacimiento fue < 1 000 g en el 12 por ciento, 1 000-1 500 g el 22 por ciento, y el resto >1 500 g. En 18 pacientes del grupo B se realizaron 2 anastomosis en segmentos intestinales diferentes. Las complicaciones postoperatorias fueron infección de herida operatoria (n:3) y dehiscencia de anastomosis (n:1). Un 7 por ciento evolucionó con síndrome de intestino corto. La mortalidad fue 11,6 por ciento, en todos los casos secundaria a sepsis. Conclusiones: En esta experiencia la Anastomosis Primaria en ECN aparece como una opción segura, con baja morbimortalidad independiente de la edad, peso, contaminación intraperitoneal o extensión de la enfermedad.

Post- infantile presentation of intestinal malrotation

To study intestinal malrotation presenting after the age of one year, analyze the spectrum of presentations and to predict risk of volvulus. Retrospective study. Zagazig University Hospitals [Egypt] and King Fahd Hospital, Saudi Arabia. All cases [54] of malrotation during April 2006 to April 2010. Analysis of clinical, radiological and operative data. Presentation, significant associations and risk of volvulus. The mean age was 4.8 +/- 2.13 years. Presentations included acute volvulus [n = 27, 50%], chronic volvulus [4, 7.5%], mesocolic hernia [4, 7.5%], intussusception [5, 9%], exomphalos [5, 9%] and non-specific presentation [9, 17%]. Associated anomalies were found in 19 cases [35%] with significant association of chronic volvulus and exomphalos. Typical anatomical malrotation was seen in 21 [39%] cases with significant risk of volvulus [odds ratio 9.2]. Nausea and vomiting, abdominal colic, and malnutrition were dominant in acute and chronic volvulus, mesocolic hernia and intussusception [p < 0.05]. Malnutrition and gastroesophageal reflux disease [GERD] were significantly associated with chronic volvulus [p < 0.05]. Duodenal obstruction was significantly evident in acute volvulus while high cecum was dominant in intussusception. Prolonged ileus and persistent symptoms were significant in chronic volvulus and mesocolic hernia [p < 0.05], while wound infection and short bowel syndrome were significant in acute volvulus. Malrotation in the post-infantile period has a wide spectrum and non-specific presentation. Risk of midgut volvulus is present, especially in typical cases, and trials must be done to predict the risk and avoid unnecessary surgery

Rupture point analysis of intestinal anastomotic healing in rats under the action of pure Copaíba (Copaifera Iangsdorfii) oil / Análise do ponto de ruptura na cicatrização de anastomose intestinal em ratos tratados com óleo de Copaíba (Copaifera Iangsdorfii) puro

PURPOSE: Analyze the mechanical strength of digestive tract scar after intestinal anastomosis surgery in animals treated with pure Copaíba oil. METHODS: 60 Wistar rats, male, about 250 days old and weighting around 350g were used. The rats were randomly divided into two groups: Group O, with 30 animals that received Copaíba oil and Group C, with 30 animals that received saline. Each group was subdivided into three subgroups, containing 10 rats each. They were designated O7, O14, O28, C7, C14 and C28, according to the post-operative assessment date at 7, 14 and 28 days, respectively. On these dates euthanasia was performed with the removal of the bowel segment containing the anastomosis and assigning the samples to tensile test for assessing Maximum Stress, Maximum Tensile Strength and Maximum Rupture Strength. RESULTS: On the three variables of the study, the results indicate that, for the three assessment periods (7, 14 and 28 days) there was no significant difference between the oil and control groups. CONCLUSION: For the mechanical tests proposed by this study, Copaíba oil didn´t show any effectiveness in increasing the anatomosis strength.

OBJETIVO: Analisar a resistência mecânica da cicatriz do tubo digestivo, após cirurgia de anastomose intestinal em animais tratados com óleo da Copaíba puro. MÉTODOS: Foram utilizados 60 ratos Wistar, machos, com cerca de 250 dias e peso médio de 350g. Os ratos foram divididos aleatoriamente em dois grupos: Grupo O, com 30 animais, que receberam óleo da Copaíba e Grupo C, com 30 animais, que receberam solução fisiológica. Cada grupo foi subdividido em três subgrupos, contendo 10 ratos cada. Suas denominações foram O7, O14, O28, C7, C14 e C28, segundo o tempo de avaliação pós-operatória em 7, 14 e 28 dias, respectivamente. Nessas datas foi realizada a eutanásia com a retirada do segmento intestinal contendo a anastomose, destinando as amostras ao teste de tração para a apreciação da Tensão Máxima, Força Máxima de Tração e Força Máxima de Ruptura. RESULTADOS: Nas três variáveis do estudo, os resultados indicam que, para os três momentos de avaliação (7, 14 e 28 dias) não houve diferença significativa entre os grupos óleo e controle. CONCLUSÃO: Para os testes mecânicos a que este estudo se propôs o óleo de Copaíba não se mostrou eficaz em aumentar a resistência da anatomose.
