Abstract Background: Post-operative delirium is a serious complication in patients undergoing major abdominal surgery. It remains unclear whether peri-operative hemodynamic and perfusion variables affect the risk for postoperative delirium. The objective of this pilot study was to evaluate the association between perfusion and hemodynamics peri-operative with the appearance of post-operative delirium. Methods: Prospective cohort study of adults 60 years or older undergoing elective open colon surgery. Multimodal hemodynamic and perfusion variables were monitored, including central venous oxygenation (ScvO2), lactate levels, and non-invasive cerebral oxygenation (rSO2), according to a standard anesthesia protocol. Fisher's exact test or Student's t-test were used to compare patients who developed post-operative delirium with those who did not (p < 0.05). Results: We studied 28 patients, age 73 ± 7 years, 60.7% female. Two patients developed post-operative delirium (7.1%). These two patients had fewer years of education than those without delirium (p = 0.031). None of the peri-operative blood pressure variables were associated with incidence of post-operative delirium. In terms of perfusion parameters, postoperative ScvO2 was lower in the delirium than the non-delirium group, without reaching statistical significance (65 ± 10% vs. 74 ± 5%; p = 0.08), but the delta-ScvO2 (the difference between means post-operative and intra-operative) was associated with post-operative delirium (p = 0.043). Post-operative lactate and rSO2 variables were not associated with delirium. Conclusions: Our pilot study suggests an association between delta ScvO2 and post-operative delirium, and a tendency to lower post-operative ScvO2 in patients who developed delirium. Further studies are necessary to elucidate this association.
Resumo Justificativa: O delírio pós-operatório é uma complicação séria em pacientes submetidos à cirurgia abdominal de grande porte. Ainda não está claro se as variáveis hemodinâmicas e de perfusão no período perioperatório afetam o risco de delírio pós-operatório. O objetivo deste estudo piloto foi avaliar a associação entre perfusão e hemodinâmica no perioperatório com o surgimento de delírio pós-operatório. Métodos: Estudo prospectivo de coorte de adultos com 60 anos ou mais, submetidos à cirurgia eletiva aberta do cólon. As variáveis multimodais de hemodinâmica e perfusão foram monitoradas, inclusive oxigenação venosa central (ScvO2), níveis de lactato e oxigenação cerebral não invasiva (rSO2), de acordo com um protocolo-padrão de anestesia. O teste exato de Fisher ou o teste t de Student foram usados para comparar os pacientes que desenvolveram delírio pós-operatório com aqueles que não desenvolveram p < 0,05. Resultados: Avaliamos 28 pacientes, 73 ± 7 anos, 60,7% do sexo feminino. Dois pacientes desenvolveram delírio pós-operatório (7,1%). Esses dois pacientes tinham menos anos de escolaridade do que aqueles sem delírio pós-operatório (p = 0,031). Nenhuma das variáveis de pressão arterial no perioperatório foi associada à incidência de delírio. Quanto aos parâmetros de perfusão, ScvO2 foi menor no grupo que apresentou delírio pós-operatório do que no grupo que não apresentou delírio, sem atingir significância estatística (65 ± 10% vs. 74 ± 5%; p = 0,08), mas o delta-ScvO2 (a diferença entre as médias no pós-operatório e intraoperatório) foi associado ao delírio (p = 0,043). As variáveis de lactato e rSO2 no pós-operatório não foram associadas ao delírio. Conclusões: Nosso estudo piloto sugere uma associação entre delta-ScvO2 e delírio e uma tendência à diminuição da ScvO2 no pós-operatório de pacientes com delírio. Estudos adicionais são necessários para elucidar essa associação.

La esclerosis tuberosa es una enfermedad autosómica dominante con gran variabilidad de expresión clínica. Se caracteriza por la presencia de tumores benignos en distintos órganos debidos a un desorden en la proliferación y diferenciación celular. Afecta, especialmente, la piel, el sistema nervioso central, el corazón y el riñón. El compromiso intestinal es infrecuente; afecta a adultos y compromete el colon sigmoide y el recto. En niños, hay solo dos casos descritos en la literatura; nuestra paciente sería el tercero. Presentamos a una paciente con esclerosis tuberosa, que comenzó, desde el mes de vida, con cuadros reiterados de suboclusión intestinal. La videocolonoscopía mostró una formación mamelonada que protruía hacia la luz del colon ascendente. Se realizó una hemicolectomía derecha. El informe anatomopatológico correspondió a un pólipo hamartomatoso. La evolución clínica y nutricional en el posquirúrgico fue muy favorable. Aunque poco frecuente, el pólipo hamartomatoso debe considerarse en el diagnóstico diferencial de oclusión intestinal en pediatría.
Tuberous sclerosis is an autosomal dominant disorder with a wide clinical spectrum of disease. It is characterized by development of benign tumors in multiple organs due to a disturbance in cellular growth and differentiation. It usually affects skin, brain, heart and kidney. Gastrointestinal involvement is rare and mainly restricted to adults and sigmoid colon and rectum. In children there are only two cases; our patient would be the third. We present a patient with tuberous sclerosis who began at the first month of life with repeated intestinal subocclusion. The videocolonoscopy showed a mass protruding into the lumen of the ascending colon. Right hemicolectomy was performed. The anatomopathological report corresponded to a hamartomatous polyp. The clinical and nutritional evolution in the postoperative period was very favorable. Although uncommon, the hamartomatous polyp should be considered in the differential diagnosis of intestinal occlusion in pediatrics.

Abstract Introduction: Takotsubo cardiomyopathy (TCM) is a stress-induced cardiomyopathy. It is characterized by an acute onset of symptoms and electrocardiographic abnormalities mimicking an acute coronary syndrome in the absence of obstructive coronary artery disease. Any anesthetic-surgical event corresponds to a stressful situation, so the anesthetic management of patients with TCM requires special care throughout the perioperative period. We describe the anesthetic management of a patient with a confirmed diagnosis of TCM undergoing segmental colectomy. Case report: Female patient, 55 years old, ASA III, with history of takotsubo syndrome diagnosed 2 years ago, scheduled for segmental colectomy. The patient, without other changes in preoperative evaluation, underwent general anesthesia associated with lumbar epidural and remained hemodynamically stable during the 2 h of surgery. After a brief stay in the Post-Anesthesia Care Unit, she was transferred to the Intermediate Care Unit (IMCU), with epidural analgesia for postoperative period. Conclusion: TCM is a rare disease which true pathophysiology remains unclear, as well as the most appropriate anesthetic-surgical strategy. In this case, through a preventive approach, with close monitoring and the lowest possible stimulus, all the perioperative period was uneventful. Because it is a rare disease, this report could help to raise awareness about TCM.
Resumo Introdução: A miocardiopatia takotsubo (MT) é uma miocardiopatia induzida pelo estresse. Caracteriza-se por um início agudo de sintomas e alterações eletrocardiográficas que mimetizam uma síndrome coronária aguda na ausência de doença arterial coronária obstrutiva. Qualquer evento anestésico-cirúrgico corresponde a uma situação de estresse, pelo que a abordagem anestésica dos doentes com MT exige um cuidado especial em todo o período perioperatório. Descrevemos a abordagem anestésica de uma doente com diagnóstico confirmado de MT submetida a colectomia segmentar. Caso clínico: Paciente do sexo feminino, 55 anos, ASA III, com antecedentes de síndrome de takotsubo diagnosticada havia dois anos, encaminhada para colectomia segmentar. A paciente, sem outras alterações na avaliação pré-operatória, foi submetida a anestesia geral associada a epidural lombar e manteve-se hemodinamicamente estável durante as duas horas do procedimento cirúrgico. Após uma breve permanência na Unidade de Cuidados Pós-Anestésicos foi transferida para a Unidade de Cuidados Intermédios (UCIM) com analgesia peridural para o pós-operatório. Conclusão: A MT é uma doença rara, cuja verdadeira fisiopatologia continua por esclarecer, assim como a estratégia anestésico-cirúrgica mais apropriada. Nesse caso, por causa de uma abordagem preventiva, com monitoração rigorosa e o menor estímulo possível, todo o perioperatório decorreu sem intercorrências. Sendo uma doença rara, o seu relato poderá contribuir para o avanço do conhecimento sobre a MT.

Se reporta dos casos de retroneumoperitoneo con neumo-mediastino, consecuencias de perforaciones diverticulares en el espacio retroperitoneal, en pacientes portadores de diverticulitis aguda y septicemia. En ambos casos no se comprobó contaminación peritoneal alguna, siendo sometidos a Colectomia parcial tipo Hartmann con buena evolución; al momento del reporte ambos han sido sometidos al restablecimiento del tránsito colo-rectal. Se discuten los problemas diagnósticos y los posibles mecanis-mos del paso del aire - y gérmenes bacterianos - al mediastino.
We report two cases of retropneumoperitoneum with pneumomediastinum, as a result of diverticular perforations in the retroperitoneal space, in patients with acute diverticulitis and septicemia. In both cases the patients underwent partial colectomy (Hartmann procedure) with good evolution, and no sign of peritoneal contamination was found. Currently both patients have undergone colorectal transit restoration. We discuss problems with the diagnosis and possible mechanism of the air and bacterial germ passage to the mediastinum.

Lower gastrointestinal complications often develop in end stage renal disease patients, and among the more problematic is recurrent colon ulcer. The exact pathogenesis of this condition is not known and there were no specific therapeutic modalities concerning this type of disease entity. We report, with a literature review, a case of recurrent colon ulcer with intermittent hematochezia in an end stage renal disease patient on long term hemodialysis that improved after conversion to peritoneal dialysis.

Spontaneous bacterial peritonitis (SBP) is the most common infection in liver cirrhosis patients, and is not a result of surgery or intra abdominal infection. Argon plasma coagulation (APC) is an endoscopic procedure used with a high-frequency electrical current for control of bleeding from gastrointestinal vascular ectasias including angiodysplasia and gastric antral vascular ectasia. This procedure is known to be safe because it uses a noncontact method. Therefore, tissue injury is minimal and up to two to three millimeters. However, we experienced a case of SBP occurring immediately after performance of APC for control of severe bleeding from angiodysplasia in the colon in a patient with liver cirrhosis and hepatocellular carcinoma.

A 94-year-old female with end-stage renal disease presents with fever, fatigue, and hematochezia. She had previously resided in Hunan Province, China, and Myanmar, and she immigrated to Taiwan 30 years ago. Colonoscopy revealed a colonic ulcer. Biopsy of the colonic ulcer showed ulceration of the colonic mucosa, and many Paragonimus westermani-like eggs were noted. Serum IgG antibody levels showed strong reactivity with P. westermani excretory-secretory antigens by ELISA. Intestinal paragonimiasis was thus diagnosed according to the morphology of the eggs and serologic finding. After treatment with praziquantel, hematochezia resolved. The present case illustrates the extreme manifestations encountered in severe intestinal paragonimiasis.

Introducción: La estenosis del colon es rara, con una incidencia de uno entre 40 mil nacimientos. El colon ascendente y transverso son los más afectados. Las manifestaciones clínicas pueden aparecer desde el nacimiento. Caso clínico: Niño de dos años 11 meses de edad, con cuadros periódicos de estreñimiento, dolor tipo cólico y distensión abdominal. La radiografía simple de abdomen mostró dilatación de asas y cuerpos extraños. El colon por enema fue normal. Por laparotomía exploradora se identificó estenosis en el colon transverso. Se practicó resección, extracción de cuerpos extraños y anastomosis término-terminal. El examen histopatológico mostró estenosis con lumen de 0.5 cm; las células ganglionares estuvieron presentes entre las capas musculares. A dos años de la cirugía, el paciente se encontraba asintomático. Conclusiones: La estenosis congénita de colon es poco frecuente. Abdu-Judeh informa un caso y refiere ocho descritos desde 1941. Las manifestaciones clínicas son estreñimiento, vómito y distensión abdominal, sin embargo, los pacientes pueden permanecer asintomáticos por periodos variables, lo que dificulta y retrasa el diagnóstico. No existe informe previo acerca de la retención de cuerpos extraños. El colon por enema y la colonoscopia son necesarios para el diagnóstico oportuno. El tratamiento electivo es la resección quirúrgica con anastomosis primaria o colostomía; una opción es la cirugía laparoscópica.
BACKGROUND: Colonic stenosis is rarely seen in pediatric practice. Its incidence has been reported as 1/40,000 births. Ascending and transverse colon are the most common sites affected. Symptoms may be present at birth. CLINICAL CASE: We present the case of a 2 year, 11 month old male. Since birth, the patient had symptoms of constipation, abdominal pain and abdominal distension. X-ray of the abdomen showed a dilated colon and foreign bodies on the right side. Barium enema was normal. The stenotic segment was resected. Foreign bodies were removed and alimentary continuity was restored by end-to-end anastomosis. The pathologist found a 5-cm lumen at the stenosis. Histological ganglion cells were present throughout the specimen. The patient evolved favorably postoperatively and was discharged 1 week after surgery. The patient has been in good health for 2 years. CONCLUSIONS: Colonic stenosis is uncommon. Abu-Judeh reported on one case and a review of the literature revealed eight cases of congenital colonic stenosis since 1941. Symptoms are abdominal distension, vomiting and constipation with symptom remission, making diagnosis difficult. This is the first report involving foreign bodies. Barium enema and colonoscopy are necessary for diagnosis. Resection of the stenotic segment with end-to-end anastomosis or colostomy is the treatment of choice. Laparoscopy is an alternative procedure.

Arterio-enteric fistula is a very rare cause of massive lower gastrointestinal hemorrhage. We report here on a case of massive hematochezia caused by iliac arterio-colic fistula in a 60-year-old woman who had a recent history of spinal surgery for herniated nucleus pulposus. Abdomen computed tomography showed the extravasation of radiocontrast media from right iliac artery encased by an intraabdominal abscess into the adjacent dilatated colon. Also, diagnostic angiography revealed the active extravasation of radiocontrast media via a fistula between right iliac artery and colon. Although successful endovascular exclusion of the fistula with stent graft and coils was performed, disseminated intravascular coagulation and multi-organ failure were developed.

A broad spectrum of colonic complications can occur in patients with colon cancer. Clinically, some of these complications can obscure the presence of underlying malignancies in the colon and these complications may require emergency surgical management. The complications of the colon that can be associated with colon cancer include obstruction, perforation, abscess formation, acute appendicitis, ischemic colitis and intussusception. Although the majority of these complications only rarely occur, familiarity with the various manifestations of colon cancer complications will facilitate making an accurate diagnosis and administering prompt management in these situations. The purpose of this pictorial essay is to review the CT appearance of the colonic complications associated with colon cancer.

Bartter's syndrome (BS) is an inherited renal tubular disorder characterized by hypokalemia, hypochloremic metabolic alkalosis, and hyperaldosteronism with normal blood pressure. A 22-year-old woman was referred at 23 week of gestation. Polyhydramnios was detected and the chloride level of the amniotic fluid was high. The mother was treated with indomethacin from 26 to 31 week of gestation. The newborn was delivered at 34 week of gestation. At 8th day of life, indomethacin was also started for the baby. After three days, a colonic perforation developed. Indomethacin-induced colon perforation is uncommon in antenatal Bartter's syndrome. This patient indicates that administration of indomethacin in both antenatal and/or early postnatal period may be associated with colonic perforation.

The association of anisakiasis of the colon with colon cancer is rare and difficult to diagnose. Only one case of this type has been reported to date. In this study, we report a case of synchronous colon cancer and colonic anisakiasis. A 50-year-old woman was admitted for abdominal pain, and a volume-rendered surface-shaded image of CT colonography (CTC) revealed a concentric narrowing in the sigmoid colon and a segmental fold thickening in the ascending colon. A total colectomy was performed and the diagnosis of synchronous sigmoid colon cancer and anisakiasis of the ascending colon was confirmed. This case is the first reported visualization of synchronous colon cancer and colonic anisakiasis on a CTC.

Malakoplakia is a rare pseudotumoral inflammatory disease known to affect immunocompromised subjects. We report a 4-year-old boy with malakoplakia of colon who was diagnosed with celiac disease in late infancy; despite aggressive nutritional and medical management for celiac disease, symptoms did not resolve. His nitro-blue-tetrazolium test was compatible with chronic granulomatous disease. In colonic biopsy Michaelis-Gutmann bodies were seen.

Complications of acute pancreatitis usually occur in pancreas and its contiguous organs. The prevalence of colonic invasion is rare, however, the consequence is fatal, with mortality above 50%. The initial symptoms and onset times are variable and major affected sites are transverse colon and splenic flexure. The spread of inflammatory exudates into the colon is the main mechanism of colonic invasion. If the colonic stenosis develops, it is necessary to manage it surgically. We report a case who arrived at the hospital with watery diarrhea and abdominal distension in the recovery period of acute alcoholic pancreatitis and was diagnosed as a colonic obstruction in the splenic flexure. The patient underwent loop ileostomy instead of the resection of the lesion because of severe adhesion around the splenic flexure. The patient died due to sepsis 5 days after the operation.

Los motivos esenciales de la cirugía ambulatoria y su desarrollo fueron los aspectos socio económicos, con una especial atención a los ingresos y estancias hospitalarias. Esta nueva modalidad de asistencia quirúrgica es creciente y la coloproctología no escapa a este desarrollo. Se definen como ventajas de la cirugía ambulatoria: Disminución de la infección nosocomial; Atención más individualizada; Cambios mínimos en el estilo de vida de los pacientes; Retorno precoz a la actividad laboral; Reducción de los costos hospitalarios; Reducción de las listas de espera para cirugía; Mayor disponibilidad de camas para la hospitalización. La coloproctología tiene un sinnúmero de procedimientos que pueden realizarse en cirugía ambulatoria. Un programa de cirugía ambulatoria tiene como objetivo realizar operaciones bajo anestesia local, regional o general en un medio seguro. Es dado de alta en el día, al cuidado de un adulto responsable. La unidad ideal en cirugía ambulatoria en coloproctología es el tipo IV (Independiente) o la tipo III (Satélite). Los criterios de selección dependen del paciente y de la patología. La evaluación preoperatorio en cirugía ambulatoria es la estándar. Hoy se discute el valor práctico de estos estudios de solicitud rutinaria. En cirugía mayor ambulatoria en coloproctología se aconseja: anestesia local + sedación analgesia o la anestesia general. Se deben evitar las anestesias espinales. El tratamiento de las enfermedades proctológicas en cirugía ambulatoria permite según su complejidad agruparlas en cirugía menor ambulatoria (CmA) o cirugía mayor ambulatoria (CMA). Una unidad de cirugía ambulatoria en coloproctología necesita una organización específica: cirujanos coloproctólogos expertos y un equipo de atención post alta cercano al domicilio del paciente con experiencia en el manejo de esta patología. Las complicaciones postoperatorias de la cirugía ambulatoria en coloproctología son: Náuseas 30 por ciento; Vómitos 20 por ciento; Dolor intenso; Retención aguda de orina 32 por ciento; Hemorragia severa 2 por ciento; Infección anal 0,6 por ciento; Impactación fecal 1 por ciento. El seguimiento postoperatorio en las primeras 24 horas del alta debe ser muy estricto: Indicaciones escritas; Teléfono para la emergencia; Sistema de traslado; Cama asegurada en un hospital; Comunicación telefónica o visita domiciliaria.

A 68-year-old woman with known severe aortic stenosis was admitted to the hospital because of hematochezia and dizziness. She had received several blood transfusions over the preceding 3 years and undergone right hemicolectomy 2 years ago for severe lower gastrointestinal bleeding. Postoperative histology revealed angiodysplasia involving the ascending colon. After the hemicolectomy, she continued to have hematochezia and anemia and required additional blood transfusions for anemia. During this admission, platelet count, activated partial-thromboplastin time, von Willebrand factor antigen, and von Willebrand factor ristocetin cofactor were normal. She had a severe deficiency of high-molecular-weight multimers of von Willebrand factor. Colonoscopy showed angiodysplasia in the transverse colon at this time. Successful coagulation of the bleeding angiodysplasia was achieved by argon plasma coagulator. No additional bleeding was observed thereafter. We report a case of Heyde's syndrome with abnormal von Willebrand factor in a patient who presented with intestinal angiodysplasia and aortic stenosis.
