Volvo gástrico agudo perfurado

The authors report a case of acute gastric volvulus in a 20-year-old male, complicated by perforation near the gastroesophageal junction and generalized peritonitis. This is an uncommon and potentially lethal conditon although our patient has been handled successfully with a partial gastrectomy.

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.

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.

Drenagem endoscópica de abscesso pancreático

Surgical drainage is still considered the gold standard treatment of pancreatic abscess. Patients with high surgical risk, however, require alternative therapy. The authors report three cases of pancreatic abscess that were treated endoscopically. In patients who met endoscopic drainage criteria, treatment was effective, though one case did require surgical intervention as a result of gastric puncture point bleeding. After this initial experience, we believe that endoscopic drainage should be considered in selected cases.

Complicação da banda gástrica ajustável videolaparoscópica para tratamento da obesidade mórbida: extrusão da banda

Various options for surgical treatment of morbid obesity have been developed with varying results: vertical banded gastroplasty with intestinal by-pass, disabsorptive surgeries and laparoscopic adjustable gastric banding. Although all of them have been effective in weight loss, lower rates of early and late postoperative complications have been described in some procedures. Laparoscopic adjustable silicone gastric banding (LASGB) has a similar principle as vertical banded gastroplasty and it is a minimally invasive procedure, with low systemic and operative problems, but not free of them. We report two rare cases of this complications of LASGB.

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.

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.

Tricobezoar gastro-duodeno-jejunal: abordagem videolaparoscópica

Trichobezoars are gastric concretions of hair that sometimes extend throught the intestine. We report on a patient with trichobezoar managed by videolaparoscopic extraction, and discuss the advantages and disadvantages of this method, that can be the treatment of choice of this conditions.

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.

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.

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.
