Extração de fitobezoar gástrico por videolaparoscopia: considerações técnicas originais

Videolaparoscopic surgery has been used for treatment of almost all surgical abdominal diseases, mainly where there are no large ressections, or operative field is limited. In these situations, laparoscopic surgery has the advantages of less morbidity, quick recovery and good cosmetic results. Bezoars removal, or its mobilization, is probably included in these possible proceedings. Three non-laparotomic procedures were described: 1. endoscopic-laparoscopic; 2. videolaparoscopy and mobilization of intestinal bezoar to the cecum; 3. laparoscopy and gastrotomy for bezoar removal, through suprapubic incision or the umbilical punction. There have been only two publications describing the videolaparoscopic method for bezoar removal, and the methods applied can be complications or morbidity related. We describe one case where the applied technique is simple and easy to perform, time saving and probably less complications-related. This technique, with four trocars, utilized a plastic bag besides the stomach to be opened, followed by gastrotomy, bezoar removal and immediate introduction in the plastic bag, suture of gastrotomy and removal through the left subcostal trocar. This technique was feasible and easy to perform, with short operative time, and there were no intra or post-operative complications; the patient was discharged in the second post-operative day, and is without further problems after one year follow-up. We believe that this could be an adequate technique to perform laparoscopic gastric bezoar removal, and the rigid sequence of operative events allows a quick procedure, with minimal contamination. The videolaparoscopy seems to be an adequate access to surgical treatment of gastro-intestinal bezoars, with or without obstruction, and should be the ellected the procedure of choice to begin the surgical treatment, with convertion to laparotomy in case of any intra-operative adversity.

Tratamento cirúrgico do schwannoma traqueal

Schwannoma is a rare benign tumor of the proximal tracheobronchial tree. The aim of the present study is to report a case of tracheal schwannoma causing airway obstruction. A 16-year-old woman complained of cough, wheezing and dyspneia. Bronchoscopy and computerized tomography showed a polypoide intratracheal mass obstructing approximately 80% of the lumen. The treatment consisted of tracheal resection and primary anastomosis. Histological analysis revealed a tracheal schwannoma. The postoperative course was uneventful and the patient remains well twelve months after surgery.

Hérnia lombar encarcerada complicada com obstrução intestinal e perfuração de ceco

Lumbar hernia is defined as an abdominal passage through the posterior abdominal wall. Approximately 250 to 300 cases have been described in the literature, being quite infrequent. Untreated lumbar hernia may result in severe complications. The authors report a case of a 60 year old male patient presenting a large bowel obstruction and perfuration secundary to incarceration of descending colon within a lumbar hernia. This was diagnosed by clinical history and computed tomography. The patient was successfully treated surgically.

Hérnia encarcerada em orifício de trocarte lateral diagnosticada por tomografia computadorizada

Incisional hernia is an uncommon complication in laparoscopic surgery. The majority of the hernias are located in the umbilical site. Nevertheless, they can occur in the lateral trocar site, although they are rarely diagnosed. We report a case of a 55 year-old patient who underwent a videolaparoscopic hysterectomy and developed small bowel obstruction on the third postoperative day. This initially gave rise to the diagnosis of paralytic ileum. The definitive diagnosis of incarcerated hernia in the lateral trocar site was established after an abdominal computed tomography was performed.

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.

Síndrome de Ogilvie: relato de dois casos tratados com cecostomia

Acute colonic pseudo-obstruction or Ogilvie’s Syndrome is characterized by signs and symptoms of large bowel obstruction without evidence of mechanical cause. The authors report two cases of patients with acute obstructive abdomen who were previously submitted to clinical treatment with no sucess. Later on one of them was submitted to laparoscopic cecostomy and the other to colonoscopic cecostomy The results showed that only the interventionist methods were successful.

Oclusão intestinal por compressas cirúrgicas intraluminais: experiência de cinco casos

Despite being unusual, retained foreign bodies after surgical procedures is a matter of great concern for surgeons. The main purpose of this article is to describe five cases of intestinal obstruction due to intraluminal surgical sponges. The average time between the first operation and the intestinal obstruction was eight months. All patients referred abdominal pain and change of intestinal habit prior to the intestinal obstruction. In two cases bowel perforation was also observed, in addition to the intestinal obstruction. Four patients had no postoperative complications. One patient died due to an intra-abdominal abscess and sepsis.

Mucocele do apêndice

Mucocele is an unusual lesion of the appendix characterized by accumulation of mucoid substance inside the appendix, which occurs as a sequel of luminal obstruction, usually by fibrous tissue. Diagnosis is intraoperative in most of the cases. We discuss the clinical, anatomicopathological and therapeutics aspects of the disease.

Teníase: uma causa rara de apendicite aguda

Acute appendicitis is the most common surgical condition of acute abdomen. Approximately 7 percent of the population will have appendicitis during their lifetime, with the peak incidence occurring between 10 through 30 years-old. Obstruction of the appendix lumen with subsequent bacterial infection initiates the pathophysiological sequence of acute appendicitis. Obstruction may have multiple causes, including fecalith, lymphoid hyperplasia (related to viral illnesses, including upper respiratory infection, mononucleosis, and gastroenteritis), foreign bodies, carcinoid tumor, and parasites. In Asia, Africa and Latin America, Enterobius vermicularis has been reported as the main parasite that causes appendix obstruction. Rarely, Taenia sp., has been pointed as a cause of parasitic appendicitis. We reported a 30 years-old patient clinically diagnosed with acute appendicitis. The appendectomy was performed through a McBurney incision. The patient's convalescence was uneventful, and he was discharged from hospital 48 hours after operation. Histological examination of the appendix showed acute appendicitis, and it was found a parasite (Taenia sp.) lying inside of the appendix lumen at a transverse section. He has received 10 mg/Kg weight of praziquantel for taeniasis treatment.

Expressão dos marcadores tumorais CD-34 e CASPASE-3 no carcinoma epidermóide de esôfago

OBJETIVO: Analisar citofotometricamente a expressão do marcador de densidade microvascular CD-34 e de apoptose caspase-3 no carcinoma epidermóide de esôfago, e correlacionar os marcadores entre si. MÉTODOS: Análise imunoistoquímica de 29 peças cirúrgicas de carcinomas epidermóides de esôfago, baseada nos índices de marcagem dos anticorpos CD-34 e caspase-3, utilizando-se sistema de citofotometria computadorizada. Comparou-se a expressão quantitativa destes marcadores, a relação entre eles, a relação com a idade dos pacientes, tamanho das lesões e classificação TNM. RESULTADOS: O valor da mediana do índice de marcagem do CD-34 foi de 72,6% e o da caspase-3 de 96,5%. Não se obteve significância estatística na correlação destes marcadores com o tamanho tumoral ou com a idade dos pacientes. Houve discreta tendência à correlação positiva entre o CD-34 e a classificação TNM. O marcador caspase-3, apesar de apresentar maior índice de marcagem que o CD-34 nestes tumores, não revelou nenhuma correlação com as variáveis estudadas. A correlação entre o CD-34 e a caspase-3 apresentou tênue tendência positiva. CONCLUSÃO: Ambos os marcadores têm boa expressão no carcinoma epidermóide de esôfago, onde o CD-34 tem menor expressividade que a caspase-3 e os mesmos não apresentam correlação entre si.

Obstrução intestinal por volvo de ceco, relato de caso

Cecal volvulus (CV) establishes the main appearance of the anomalies related to intestinal malrotation. Diagnosis is based on signs and symptoms compatible to intestinal obstructions and complementary examinations as: single radiography form abdomen, opaque enema, computerized tomography and colonoscopy. Therapeutics modalities include: colonoscopy reducing, cecopexy and right colectomy. This article reports a CV case giving emphasis in different diagnosis and therapeutics behaviors.

Hérnia de Littré causando obstrução intestinal

The authors describe a case of a 60-year-old male with a history of a mass and pain at the right inguinal and epigastric areas. He also reported symptoms of bowel obstruction. Physical examination revealed a mass at right inguinal area, which was not reducible or pulsatile. Surgical findings included hernial sac contents with loop of ileum with signs of ischemia and a Meckel's diverticulum. Histopathological examination showed herniation of the Meckel diverticulum -Littré hernia. The article discusses the history and the incidence of this rare form of hernia.

Perfuração de intestino delgado por doença diverticular jejunal

Small Intestine's diverticulosis is an uncommon pathology of intestine. It's more evident at jejune and can be complicated by intestinal perforation, obstruction or diverticulitis, increasing the mortality. We describe a forty years old female patient that arrived at emergency service complained of diffuse abdominal pain. There aren't signals of peritonitis and the radiological evaluation showed small intestine's distension. Surgical intervention was performed revealing multiples diverticulums at jejune and intestinal perforation. The aim of this article is present a case of Small Intestine's diverticulosis and its complications that had precise intervention resulting in a favorable resolution.

Volvo de ceco complicado por icterícia séptica

Cecal volvulus is an uncommon cause of acute bowel obstruction in adults. The mechanism is torsion of the enlarged, poorly-fixed or hypermobile cecum. Patients with this condition may display highly variable clinical presentations, ranging from intermittent, self-limiting abdominal discomfort to acute abdominal pain associated with intestinal strangulation and sepsis. The treatment needs to be individualized for each case, but surgical management is required in almost every case. In the presence of gangrene or perforation of the cecum, resection and primary ileocolic anastomosis is recommended. However, in non-complicated cases detorsion and cecopexy are adequate. The authors report one case of cecal volvulus in a 55-year-old women treated with cecopexy that complicated with septic jaundice.

Hérnia paraduodenal esquerda

A left paraduodenal hernia is a protrusion of the small intestine through the paraduodenal fossa, a congenital defect situated to the left of the fourth portion of the duodenum. Imaging studies often play a central role in diagnosing left paraduodenal hernias, as they are not easily identified clinically. Surgery is the treatment of choice. We report a case of left paraduodenal hernia in a 27-year-old female patient. The patient had shown no symptoms until six days before hospitalization. A CT scan suggested the diagnosis of left paraduodenal hernia. After an unsuccessful laparoscopic attempt, a laparotomy was performed. Open surgery consisted in removing adhesions between the hernia and peritoneum, reducing jejunal loops and closing the paraduodenal fossa. The postoperative period was uneventful, and the patient was discharged on the third postoperative day.
