La paniculitis mesentérica es un proceso inflamatorio crónico inespecífico del tejido adiposo mesentérico (1) con una forma de presentación muy variable. Para su diagnóstico definitivo suele ser necesario recurrir a la toma de biopsia de la lesión debido a la falta de especificidad de las pruebas radiológicas y la incapacidad de reconocer mucho de los factores precipitantes. Actualmente se reconoce que esta entidad presenta varios estadios evolutivos. Los criterios diagnósticos anato

To assess the results of laparoscopic colorectal surgery in patients who have previously undergone abdominal surgery. Between November 2002 and June 2004, 86 patients underwent laparoscopic surgery for colorectal disease at our hospital. Patients were divided into 2 groups depending on whether they had previously undergone abdominal surgery (previous surgery group, n = 27) or not (nonprevious surgery group, n = 59). Data were prospectively collected for statistical analyses of demographic, clinical, and histologic variables. Groups were comparable in age, body mass index, American Society of Anesthesiologists score, diagnosis, technique performed, and tumor size and distance to anal verge. There was no difference in perioperative complication rates. A higher conversion rate was found in the previous surgery group (26.1% vs. 5.1%, P = 0.02). In patients with tumor diseases, resection evaluations were no different regarding specimen length, distal and radial resection margins, or number of lymph nodes harvested. Laparoscopic colorectal surgery has proved to be a reliable technique for patients who have previously undergone abdominal surgery, its results comparable to those obtained with patients who have not.

Preoperative endoscopic tattooing is a safe and effective technique for intraoperative localization of advanced colorectal neoplasms, improving the operative results of LSCRC.

We describe a case of huge mucinous cystic tumor of the pancreas in a 26-year-old woman during pregnancy. Ultrasonography demonstrated a well-delimited cystic mass in the left upper abdominal quadrant, suggestive of benignity. Magnetic resonance imaging showed a large cystic mass resembling a mucinous cystic tumor of the pancreas. After this assessment the patient underwent surgical exploration and a huge cystic tumor of the pancreas was discovered. The tumor was enucleated and distal pancreatectomy was performed. The resected margin of the specimen was free of tumor. In this case report we discuss the management of mucinous pancreatic tumors during pregnancy and we briefly review the previously reported cases of mucinous pancreatic tumors in pregnant patients. We conclude that surgical resection of these tumors should be strongly considered in pregnancy. Removal of the tumor appears to be a safe procedure without harmful effects to the fetus.

LSRC has been a reliable and efficient technique during the learning curve at our hospital.
