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.

Gastrinoma primáro de fígado

Gastrinomas are generally localized in pancreas, duodenum and lymphonodes, within the so called "gastrinoma's triangle" . In 5% of the cases, it may arise from liver, stomach, ovarium, kidneys, parathyroid, omentum, jejunum and heart. We describe a case of a fifteen-year-old boy with a primary gastrinoma of the liver, treated by right-hepatectomy.

Cisto de duplicação gástrica com parênquima pancreático ectópico em adulto assintomático

The authors describe a rare case of a gastric duplication cyst in a 55-year-old man. The past history revealed that the patient was treated one year before for gastroduodenal ulcer. The cyst was discovered incidentally at upper gastrointestinal endoscopy. Biopsies showed inflammation without evidence of tumor. On abdominal ultrasonography and CT scan, a left upper quadrant mass was noted. At laparotomy, a mass measuring 6,0 cm in contact with the stomach was excised. Histopathology showed a gastric duplication cyst containing pancreatic mucosa.

Úlcera gástrica terebrante e pancreatite aguda provocadas por tricobezoar

Bezoar is a foreing body whitin the digestive tract originated from ingestion of varied substances, mainly vegetal fiber or hair. We present a case of a 14-year-old girl with trichotillomania, gastric trichobezoar, gastric ulcer and acute pancreatitis. The patient was operated on for anterior gastrotomy and removal of trichobezoar, with good postoperative follow-up. We illustrate this case to emphasize the need for recognition of gastric ulcer with acute pancreatitis and surgical management.

Pseudoaneurisma gigante de artéria esplênica

Splenic artery pseudoaneurysm larger than 10 cm is a rare condition. The risk of rupture is probably high and surgical treatment is necessary. The objective of this article is to report a case of a patient with giant pseudoaneurysm of the splenic artery submitted to surgical resection. A 26-year-old man complaining of gastrointestinal hemorrhage and abdominal pain The patient’s medical history revealed that one year before he had an abdominal blunt trauma. The angiography showed a giant pseudoaneurysm of the splenic artery with compression of the stomach. The patient was operated on by abdominal access and the spleen and pseudoaneurysm were resected. The postoperative course was uneventful and the patient was discharged 13 days after surgery without problems.

Arma branca retida em aorta abdominal superior

Abdominal aorta wounds carries a high immediate mortality. Few patients reach hospital care alive. There are no reports on Medline (1969-2002) about aortic wounds of foreign body with retention. A case with upper abdominal aortic wound with an inlaid blade is reported. The retained blade fixed the stomach to the surgical field, difficulting the vascular control, leading to an unconventional approach and allowing extensive contamination. The patient developed multiple organ dysfunction and died at fifth postoperative day. Singularities of an inlaid knife in upper abdominal aorta and changes in traditional approach are discussed. The authors assumed that the inlaid knife decreased the bleeding, allowing the patient arrival to the hospital, but worsened the approach to the aorta wound.

Tumor carcinóide de estômago tipo 1

Gastric carcinoid occurs in less than 1% of gastric neoplasias and around 2% of carcinoids tumors. They are classified into three forms: type 1, associated with atrophic gastritis, type 2, associated with multiple endocrine neoplasia 1 and Zollinger Ellison syndrome, and type 3, a sporadic tumor. This study report a case of gastric carcinoid type 1, which manifested with chronic anemia, dyspeptic symptoms and hypergastrinemia. A 44 years old female patient, presented multiple lesions with diameter between 3 and 20 mm, with lynphonodal metastases. A total gastrectomy was performed associated with lymphnodes ressection and Y Roux reconstruction.

Hemorragia digestiva por tumor estromal gástrico

Gastrointestinal stromal tumors account for 0.1 to 3% of all resected gastric tumors and are the most common submucosal mass found in the stomach. Preoperative diagnosis is often difficult; consequently surgery is the best and only option on most cases. There are studies with different surgery techniques based on tumors location. The reported case led us at literature review with the intent of establishing preoperative diagnosis, therapeutic strategies and prognosis.

Rotura gástrica por barotrauma

Barogenic rupture of the stomach is a rare complication following cardiopulmonary resuscitation, administration of nasal oxygen by catheter and diving accidents. We report a case of gastric barotrauma following oroesophageal intubation. In most cases, the tears occur along the lesser curvature, what have been already attributed to Laplace's formula and, more recently, to morphological features of the stomach.

Câncer gástrico após gastroplastia para obesidade mórbida

We report a case of patient in whom a gastric remnant cancer developed about five years after a gastric bypass for morbid obesity. We review the literature on gastric cancer after gastroplasty. Access of gastric remnant after gastroplasty (Fobi-Capella) prevents evaluation and treatment of its disorders.

Adenocarcinoma e tumor estromal (GIST) sincrônicos no estômago: uma rara ocorrência

A concomitant epithelial and stromal tumor in stomach is unusual in the literature. The purpose of this paper is to report the case and it's therapeutic management. A 72 year old black male patient , which upper digestive endoscopy showed a gastric neoplasm (Borrmann III) at incisura angularis and the biopsy revealed adenocarcinoma. A subtotal gastrectomy with D2 limphadenectomy and Roux-en-Y reconstruction was performed. The histopathology studies confirmed an adenocarcinoma and a gastric stromal tumor, whose immunohistochemical exam was compatible to GIST. Seventeen months after surgery, a computadorized tomography revealed a retrogastric tumor and laparotomy was indicated to remove the lesion.

Tricobezoar gástrico: relato de caso

Bezoars are foreign bodies impacted in the digestive tract resulting of their ingestion and accumulation, involving mainly the stomach. The most common types are phytobezoars, contaning vegetables, fiber and seed and the trichobezoar, made of hair. The present case is the description of a 25-year-old female with nonspecific dyspeptic symptoms associated to intestinal habit change. The diagnosis was suggested by Computerized Tomography in association with clinical history - initially omitted by the pacient - of trichophagia for 10 years. Treatment consisted of Anterior Gastrotomy and remotion of the bezoar.

Lipoma gástrico: relato de caso

We report a case of gastric lipoma, a rare benign stomach tumor. There are approximately 200 cases previously described in literature. A male, 62-year-old patient with no clinical complaint presented a tumor lesion in the stomach antrum found in a routine upper endoscopy. A surgical resection (subtotal gastrectomy) was done and the histological examination showed submucosal lipoma without signs of malignancy. This report points to the growth of routine examination in the current clinical practice and the dilemma brought by overdiagnosis.

Lymph node metastasis in early gastric cancer

OBJECTIVE: to evaluate the incidence of lymph node metastasis in early gastric cancer, identifying risk factors for its development. METHODS: we conducted a prospective study of patients with gastric cancer admitted to the Section of the Esophago-Gastric Surgery of the Surgery of Service HUCFF-UFRJ, from January 2006 to May 2012. RESULTS: the rate of early gastric cancer was 16.3%. The incidence of nodal metastases was 30.8% and occurred more frequently in patients with tumors with involvement of the submucosa (42.9%), in those poorly differentiated (36.4%), in tumors larger than 2 cm (33.3%) and in type III ulcerated lesions (43.8%). CONCLUSION: the incidence of lymph node metastases in patients was very high and suggests that one should keep the radicality of resection in early gastric cancer, particularly in relation to D2 lymphadenectomy, recommended for advanced gastric cancer. Conservative resections, with lymphadenectomies smaller than D2, should be performed only in selected cases, well-studied as for the risk factors of lymph node metastasis. Despite the small number of cases did not permit to relate the rate of lymph node metastasis to the risk factors considered, we noted a strong tendency for the occurrence of these metastases in the poorly differentiated, type III, larger than 2 cm tumors, and in the Lauren diffuse types.

Natural history of extensive diaphragmatic injury on the right side: experimental study in rats

OBJECTIVE: To evaluate the natural healing of the rat diaphragm that suffered an extensive right penetrating injury.METHODS: Animals were submitted to an extensive penetrating injury in right diaphragm. The sample consisted of 40 animals. The variables studied were initial weight, weight 21 days after surgery; healing of the diaphragm, non-healing of the diaphragm, and herniated abdominal contents into the chest.RESULTS: Ten animals were used as controls for weight and 30 animals were operated. Two animals died during the experiment, so 28 animals formed the operated group; healing of the diaphragm occurred in 15 animals (54%), 11 other animals showed diaphragmatic hernia (39%) and in two we observed only diaphragmatic injury without hernia (7%). Among the herniated organs, the liver was found in 100% of animals, followed by the omentum in 77%, small bowel in 62%, colon in 46%, stomach in 31% and spleen in 15%. The control group and the diaphragmatic healing subgroup showed increased weight since the beginning of the study and the 21 days after surgery (p <0.001). The unhealed group showed no change in weight (p = 0.228).CONCLUSION: there is a predominance of spontaneous healing in the right diaphragm; animals in which there was no healing of the diaphragm did not gain weight, and the liver was the organ present in 100% the diaphragmatic surface in all rats with healed diaphragm or not.
