Background : Gastrointestinal mesenchymal or stromal tumors (GIST) are lesions originated on digestive tract walls, which are treated by surgical resection. Several laparoscopic techniques, from gastrectomies to segmental resections, have been used successfully. Aim : Describe a single center experience on laparoscopic GIST resection. Method : Charts of 15 operated patients were retrospectively reviewed. Thirteen had gastric lesions, of which ten were sub epithelial, ranging from 2-8 cm; and three were pure exofitic growing lesions. The remaining two patients had small bowel lesions. Surgical laparoscopic treatment consisted of two distal gastrectomies, 11 wedge gastric resections and two segmental enterectomies. Mechanical suture was used in the majority of patients except on six, which underwent resection and closure using manual absorbable sutures. There were no conversions to open technique. Results : Mean operative time was 1h 29 min±92 (40-420 min). Average lenght of hospital stay was three days (2-6 days). There were no leaks, postoperative bleeding or need for reintervention. Mean postoperative follow-up was 38±17 months (6-60 months). Three patients underwent adjuvant Imatinib treatment, one for recurrence five months postoperatively and two for tumors with moderate risk for recurrence . Conclusion : Laparoscopic GIST resection, not only for small lesions but also for tumors above 5 cm, is safe and acceptable technique.

INTRODUÇÃO: Hérnia incisional é uma complicação freqüente da laparotomia. O reparo por sutura simples tem elevadas taxas de recorrência, e apesar do uso de prótese diminuir o risco de recidiva, ainda é elevado. Na década de 1990, o reparo laparoscópico da hérnia incisional ganhou popularidade. Os benefícios incluem redução no risco de complicações, menos dor e rápido retorno às atividades. Além disso, pode diminuir a taxa de recorrência. OBJETIVO: Apresentar experiência com o tratamento laparoscópico das hérnias incisionais. MÉTODO: Entre janeiro de 2007 e julho de 2010, 45 pacientes foram submetidos à reparo laparoscópico de hérnia incisional. Indicações incluíram espaço suficiente para posicionamento dos trocarteres e adequada sobreposição da prótese em relação ao defeito herniário. As contra-indicações foram: co-morbidades severas que limitavam o uso de pneumoperitônio e/ou anestesia geral, assim como histórico de peritonite difusa devido ao risco elevado de aderências intra-abdominais. RESULTADOS: O tempo operatório médio foi de 76 minutos. Houve apenas uma (2,2%) complicação intra-operatória. Não houve nenhuma conversão. O tempo de internamento hospitalar foi igual ou inferior a 24 horas em 38 pacientes (84,4%). Quinze pacientes (33%) apresentaram complicações. Entretanto, 14 foram complicações menores (11 seromas indolores e 3 dor prolongada) e apenas uma complicação maior (perfuração tardia de ceco). Houve apenas uma recidiva (2,2%) após seguimento médio de 24,6 meses. CONCLUSÕES: O reparo laparoscópico das hérnias incisionais é alternativa segura, viável e eficaz. Parece estar associado a menores taxas de complicações perioperatórias e tempo de internamento quando comparado ao reparo aberto.INTRODUCTION: Incisional hernia is a frequent complication of laparotomy. Repair by simple suture has high relapse rates, and despite the use of prosthesis, risk of recurrence is still high. In the 1990s, laparoscopic repair of incisional hernia gained popularity. Benefits include reduced risk of complications, less pain and faster return to daily activities. Moreover, it can decrease the recurrence rate. AIM: To present our experience with laparoscopic treatment of incisional hernias. METHODS: Between January 2007 and July 2010, 45 patients underwent laparoscopic repair of incisional hernia. Indications included sufficient space for placement of trocars and adequate overlap of the prosthesis over the hernia defect. Contraindications were severe comorbidities that limited the use of pneumoperitoneum and/or general anesthesia, as well as history of diffuse peritonitis due to high risk of intra-abdominal adhesions. RESULTS: Mean operative time was 76 minutes. There was only one (2.2%) intraoperative complication. There was no conversion. Duration of hospitalization was equal to or less than 24 hours in 38 patients (84.4%). Fifteen patients (33%) had complications. However, 14 were minor complications (11 painless seromas and 3 prolonged pain) and only one major complication (late perforation of cecum). There was only one recurrence (2.2%) after a mean follow up of 24.6 months. CONCLUSIONS: Laparoscopic repair of incisional hernia is safe, feasible and effective. Seems to be associated with lower rates of perioperative complications and length of stay compared to open repair.
