Large intestine obstruction complicated with perforation: a rare manifestation of Schistosoma mansoni infection.

The authors report a case of a 25 year old Brazilian man with a history of crampy abdominal pain in the left iliac fossa for 2 weeks, abdominal distention, mucous diarrhea and anorexia. The patient presented signs of hemodynamic instability and a hard mass palpated in the left iliac fossa presented peritoneal irritation. At laparotomy, fecal peritonitis and a punched-out perforation of the midsigmoid colon were found. A left hemicolectomy was performed with terminal colostomy. Specimen examination revealed a thickened rectosigmoid wall, narrow lumen and multiple mucosal polyps. Microscopically, chronic granulomatous colitis with Schistosoma mansoni eggs confirmed the etiology. To the authors' knowledge, this is the first case of obstruction complicated with perforation due to mansoni schistosomiasis reported in the literature.

Surgical resection of traumatic spleen cysts by laparoscopy.

Surgical resection of traumatic cysts by means of laparoscopy in two female patients is reported. The patients had sustained severe trauma in the left upper quadrant, were symptomatic and developed large splenic cysts found by computerized tomography, with an average diameter of 8.5 cm. Both patients were submitted to puncture and capsule removal by means of videolaparoscopy and diathermy; splenic parenchyma was preserved and the cyst's bed drained. No intra or postoperative complications occurred. After an average 21 months postoperative follow-up, both patients are symptom-free and no late recurrences were found on tomographic studies. The advantages of this technique over others that have been reported are the preservation of splenic parenchyma, its easy performance and efficient relief of symptoms, as well as being minimally invasive, associated with minimal postoperative pain, shorter length of hospital stay, and no early recurrences.

Spontaneous hematoma of the rectus abdominis sheath: a review of 177 cases with report of 7 personal cases.

Hematoma of the rectus abdominis muscle sheath is a little known and rarely diagnosed condition, in spite of its definite clinical setting and treatment. It is very important to the surgeon, as it may be mistaken frequently for acute inflammatory abdominal conditions and should be considered in the differential diagnosis of intra-abdominal tumors. The literature on 177 cases of non-traumatic hematomas of the rectus abdominis muscle sheath is reviewed, including seven personal cases reported by the authors. Its epidemiology, pathogenesis, clinical features, diagnostic examinations and treatment are discussed.

[Abdominal liposarcomas].

Abdominal liposarcomas are a rare group of tumors and their principles of treatment are based in accumulated experiences of retrospective series. PURPOSE--To report seven cases of abdominal liposarcomas and to discuss the main diagnostic and therapeutic aspects of these tumors nowadays. METHODS--Seven patients operated for abdominal liposarcomas were in the Surgical Gastroenterology Discipline of Escola Paulista de Medicina (UFESP) during 30 months. The major clinic, ultrasonographic, tomographic, surgical and histopathological features were collected in each case. RESULTS--Authors call attention to the unusualness of these tumors, their propensity (while primary) to grow in their own place, without invading the tissues around or metastasizing, and when they are recurrent to their more aggressive malignity. They consider that computerized tomography is the most useful diagnostic procedure and they discard the need of percutaneous biopsy (guided or not) in the preoperative period. They emphasize the fundamental role of radical excision surgery in these tumors treatment and also emphasize the importance of the resection with proper margins, even if an associated resection of visceral organs is necessary. They consider that now radiotherapy and chemotherapy are not very effective methods to the adjuvant treatment of these tumors. CONCLUSION--It is important an accurate follow-up of the operated patients in order to indicate, when necessary, repetitive resection surgeries, even if they are palliative (citoredution surgeries), with the purpose of improving the expectation of life.
