Fístula colecistogástrica

The authors report two cases of cholecistogastric fistula, both in female patients. These patients presented abdominal pain and dispeptic hipostenic syndrome, being diagnosed as calculous cholecistopathy. ln one patient, gastroduodenoscopy showed a fistula orifice in the stomach. ln the other case, the diagnosis was only made during the operation. The surgical procedure was cholecistectomy and gastric suture, with satisfatory postoperative evolution.

Leiomiomas do esôfago removidos por vídeo-toracoscopia

This report describes three cases of esophageal leiomyomas successfully resected by thoracoscopy. Surgical enucleation through minimally invasive surgery is the treatment of choice for esophageal leiomyoma. The conventional approach through a formal thoracotomy has the potential of causing excessive pain and patient discomfort. Moreover, the hospital stay and the recovery period are prolonged. Indications for surgery were based mainly on the size of the mass (<4 cm) and the presence of dysphagia. In one case there was a clear suspicion of malignancy. The tumour was located in the lower thoracic esophagus (case 1), in the middle thoracic esophagus (case 2) and in the upper esophagus (case 3). The CT was useful in identifying the relationship between the lesion and the organs of the mediastinum. The barium swallow study was able to locate the lesion along the esophagus. The endosonography determined the boundaries of the lesions. A right thoracoscopic approach was undertaken. Dissection of the esophagus around its entire perimeter was never necessary because all tumours were anterior or right sided. The tumours were better grasped with a traction suture than with forceps. The hidrodissection was very helpful. The water-soluble contrast swallow, performed on the fourth postoperative day, was normal. Clinical results were satisfactory in all patients. Biopsies should never be performed when the mucosa overlying is normal.

Íleo biliar: enterolitotomia videoassistida

Treatment, morbidity and mortality of patients with gallstone ileus depend on an accurate diagnosis made in time, and also on a more adequate therapeutic option.A detailed clinical evaluation is fundamental for such diagnosis. Complementary exams like a simple radiological study of the abdomen, high and low endoscopies, an ultrasonography, and a tomography can also be performed. The therapeutic options include the removal of the obstructive factor separately, the performance of a treatment in two separate stages, or the performance of a complete treatment (removal of the calculus, cholecystectomy, and the closing of the fistula).This study aims to present a case report of an elderly man of high surgical risk, presenting gallstone ileus. He was submitted to an isolated videoassisted enterolithotomy through a minilaparotomy. Taking into consideration the patient’s advanced age and the lack of evidence as to other biliary associated pathologies, the chosen treatment seemed to be a good alternative. The evolution was good, and after an 8 month follow-up the patient was found well and with no biliary symptoms whatsoever.

Hérnia diafragmática traumática crônica e fístula gastropleurocutânea

Traumatic diaphragmatic hernia is defined as a laceration of the diaphragm with an abdominal viscera herniation into the thorax. It is usually asymptomatic, with the exception of the cases with obstruction, strangulation, necrosis or perforation of the herniaded viscera. It is classified as acute, latent or chronic, in accordance with the evolutive period. At the latent phase, symptoms are indefinite and the radiological signals, which are suggestive of thoracic affections, are frequent and can induce a diagnosis error, leading to inadequate treatment.This article presents a case of chronic traumatic diaphragmatic hernia which was complicated by a gastricpleuralcutaneous fistula, due to an inadequate thoracic drainage. Considering that this is a chronic affection with an unquestionable surgical indication, due to the complications risk, it is essential to have a detailed diagnostic investigation, which aims at both avoiding an intempestive or inadequate therapeutics behaviour and reducing the affection morbimortality. Recently, the videolaparoscopic approach has proved to be more precise when compared to the other diagnostic methods, by direct visualization of the diaphragmatic laceration, allowing its correction by an immediate suture.

Fístulas digestivas no trauma

Digestive fistulas are associated with significant morbidity and mortality, representing mayor challenges regarding diagnosis and the requiring management according physiopathologic basis, including hydroeletrolytic therapy, antibiotics, nutritional support, selected surgical handling and skin care. Most of these lesions are postoperative complications, especially in urgency and traumatic situations. Our objective is to revise important aspects regarding gastrointestinal tract fistulas secondary to trauma, emphasizing classification, physiopathology, diagnosis, complications and treatment.

Necrose da mucosa esofágica como complicação da cardiomiotomia à heller para tratamento de megaesôfago chagásico

This article presents a complication of the laparoscopic technique for Heller cardiomyotomy and anterior fundoplication. This procedure is safe and provides excellent relief of disphagia in esophageal achalasia. Nevertheless, there are rare but dangerous complications, such as late active digestive bleeding, presented in this paper which was resistant to conservative treatment and led to hypovolemic shock. Urgent laparotomy performed to identify and control bleeding, revealed necrosis of esophageal mucosa with a bleeding gastric vessel. Inadequate exposure of the gastroesophageal junction and an incision very close to the lesser curvature might have damaged the esophageal branches of the left gastric artery, leading to ischemic necrosis of the mucosa and exposure of the gastric wall and its vessels.

O uso do tubo colônico bipediculado microcirúrgico na reconstrução do esôfago

In some cases of esophageal reconstruction, it is not possible to use the gastric tube. In those cases, the second option is the reconstruction with a colonic segment. In the present paper, the authors present the use of microsurgical technique to improve vascular supply in esophageal reconstructions using the colon. Therefore, the transposed segment becomes perfused by two vascular pedicles: a proximal one and a distal one. The authors describe a case of 52 years-old patient, suffering of middle third esophagus carcinoma, who underwent a primarily esophageal resection with an unsuccessful reconstruction using gastric transposition. A new reconstruction was proposed using a bipedicle microcirurgical colonic tube, four months later. The post operative was uneventful with rehabilitation of swallowing and satisfactory recovery of nutritional state.

Emprego da submucosa intestinal suína em uretroplastias complexas

We report the use of Porcine Intestinal Submucosa (PIS) in association with Johanson technique for urethroplasty, in the treatment of recurring urethral stenosis. The patient had obliterans xerotica balanitis and had previously undergone 15 internal uretotomies as well as various unsuccessful urethral dilations. As a result of stenotic extension, another surgery was planned using Johanson technique. During the first part of the surgery, intense local fibrosis was observed, which required greater care and protection to avoid fistulae formation. PIS was interposed to reduce the chances of the occurrence of this dreaded complication. During the second part of the surgery, a skin flap obtained from tissue parallel to the urethral plateau was used to prepare a neourethra according to the norms of this technique. PIS was fixed at its extremities, and interposed between the neourethral suture and the skin suture to prevent any contact between them. The procedure was completed with the use of meatoplasty and glandulaplasty. After 6-month follow up, clinical and urodynamic improvement could be seen. If these results can be confirmed by more extensive studies, PIS will provide new perspectives for complex urethroplasties.

Hemoptise como manifestação de aneurisma de aorta torácica descendente

Aortotracheal fistula is a rare condition that is invariably fatal if not diagnosed and surgically treated. Patients usually present with small intermittent hemoptysis. The findings using computerized tomography (CT) are usually diagnostic. CT should be considered in the initial investigation of patients suspected to have such a disease. A 62-year-old woman with a aneurysm of the descending thoracic aorta presented with new-onset back pain and hemoptysis. The hemoptysis was thought to be the result of invasion of the bronchial tree by the aneurysm.

Leiomiossarcoma do esôfago

The authors describe a case of esophageal leiomyosarcoma treated at the Abdominopelvic Surgery Department of the Brazilian National Cancer Institute, including literature review, addressing treatment and prognosis. A 45 year-old female patient complaining of dysphagia, with pre-operative exams sugestive of esophageal leiomyoma. She was submitted to an esophagusgastrectomy with digestive reconstitution using a gastric tube brought through the posterior mediastinum. The histopathological examination and immunohistochemical tests confirmed that the tumor was an esophageal leiomyosarcoma. She is at the 7th year of follow up with no recurrence nor digestive complains.

Obstrução intestinal após uso de infliximab no tratamento de fístula êntero-cutânea na doença de Crohn

Crohn's disease is often complicated by the development of fistulas. Infliximab, a monoclonal antibody that binds tumor necrosis factor a have shown to be successful in the treatment of fistulizing Crohn's disease. It's possible complications and side effects have not been completely elucidated. Our objective is to report a case of a patient who developed intestinal obstruction after treatment of fistulizing Crohn's disease with infliximab. A 50 years-old female with Crohn's disease presented with spontaneous enterocutaneous fistula. She was successfully treated with the infusion of 5mg/kg infliximab at weeks 0, 2, and 6, with complete closure of the fistula after the first infusion. Eight weeks after treatment she developed small bowel obstruction secondary to stenosis of the ileum. She was subjected to exploratory laparotomy and resection of the stenotic ileum. The patient had good recovery, with no complications, and was discharged on the 5th postoperative day. Although a faster and complete healing of enterocutaneous fistula was induced by infliximab, this treatment may have caused intestinal obstruction in this case.

Exérese de leiomioma esofágico por toracotomia

A 49yrs old, male patient presented progressive dysphagia during the last two years, initially to solids and, since two weeks, liquids he had lost 15 kilos. Esophagogram showed an intraluminal lesion with regular mucosa in the middle third of esophagus. The esophagoscopy exhibits regular mucosa up to the lesion, which did not alow passage. There was no evidence of linfonodal disease at CT scan. The hypothesis of esophageal leiomyoma led this patient a right posterior thoracotomy and enucleation of a 30 x 30 mm mass from the esophageal wall. With this case report we intend to review esophageal leiomyomas and their diagnosis and treatment.

Divertículo de Zenker: relato de três casos

Pharyngoesophageal diverticula are epithelial-lined pouches that protrude from the esophageal lumen. They were studied by Zenker in 1878,receiving the denomination of Zenker's diverticulum. They are false diverticula since they don't have all layers of the esophageal wall. Although they are most common esophageal diverticula . Their incidence is of 3% of the patient presenting dysphagia. Current , there are several therapeutic modalities, from dilatation of the esophagus to surgery with resection of the diverticulum. The report refers to three patients with Zenker's diverticulum who underwent conventional surgical treatment.

Cisto de úraco em adultos simulando abdômen agudo

Urachus anomalies are generally asymptomatic, but when infected can simulate acute abdomen. This anomaly has to be deemed when abdominal tenderness is associated with inflammation signs in parumbilical or hypogastric regions. Ultrasonography has great sensibility to settle down the diagnosis as observed from our three cases. Ultrasonography images with air suggest intestinal fistula in most cases with sigmoid or ileum as shown here.

Fatores preditivos de morbimortalidade no trauma de intestino delgado

OBJETIVO: Os objetivos deste estudo foram avaliar o diagnóstico e o tratamento das lesões de intestino delgado e determinar os fatores que influenciaram a morbimortalidade. MÉTODO: Estudo retrospectivo incluindo 410 pacientes com lesão de intestino delgado operados entre janeiro de 1994 e dezembro de 2004. Os dados coletados incluíram: mecanismo de trauma, métodos diagnósticos, tempo transcorrido até a intervenção cirúrgica, grau das lesões, índices de trauma, conduta cirúrgica (sutura ou ressecção e anastomose), morbidade (especialmente fístula) e mortalidade. A comparação entre os grupos foi feita usando os testes de Fisher e Yates. RESULTADOS: O mecanismo de trauma foi penetrante em 321 pacientes (78,3%) e fechado em 89 (21,7%). Houve mais pacientes tratados cirurgicamente com intervalo maior que 6 horas após o trauma no grupo trauma contuso se comparados com trauma penetrante (p<0,05). Sutura da lesão foi feita em 52,2% dos pacientes e ressecção e anastomose em 46,8%, e ambos procedimentos apresentaram a mesma incidência de fístula (4,7%). A morbidade foi de 35,1%. A incidência de fistula foi maior nos pacientes submetidos à laparotomia com mais de 12 horas após o trauma quando comparados com aqueles operados com menos de 12 horas (8,3% vs. 4,3%; sem diferença estatística), mas isto não foi fator determinante para maior mortalidade. A mortalidade foi de 13,7% e foi relacionada com escores de gravidade mais elevados. CONCLUSÃO: A lesão de intestino delgado é freqüente após o trauma abdominal, sendo mais comum nos traumas penetrantes. O diagnóstico desta lesão após trauma fechado pode ser difícil, com demora para o tratamento cirúrgico. A ocorrência de fistula não esteve relacionada aos seguintes fatores analisados: mecanismo de trauma, tempo transcorrido entre o trauma e a operação, conduta cirúrgica, lesões intra-abdominais associadas ou gravidade das lesões. A mortalidade esteve relacionada com lesões associadas.
