Laparoscopic treatment of retroperitoneal cystic mesothelioma. Two cases reported.

Retroperitoneal cystic mesothelioma is a very rare lesion. The pathogeny is unclear and establishing a preoperative diagnosis versus others retroperitoneal cystic lesions is difficult. Thus, with increasing experience in laparoscopic retroperitoneal surgery, the use of this approach for exploration of a retroperitoneal mass of unknown origin may provide an alternative to classic open surgery and all the benefits of laparoscopy.

[Hepatic myelolipoma. Diagnosis and treatment].

Myelolipoma is a very uncommon tumor and is extremely rare in the liver. Patients are usually asymptomatic and preoperative diagnosis is often difficult. We report a new case of hepatic myelolipoma and review all the cases previously reported in the literature.

[Complications due to spilled gallstones and surgical clips left in the abdomen during laparoscopic cholecystectomy].

The presence of biliary gallstones and surgical clips in the abdominal cavity after a laparoscopic cholecystectomy can cause complications, which even though they are uncommon, can be serious. We carried out a review of the various complications, their incidence, related risk factors, ways to deal with them and recommendations to reduce morbidity associated with the presence of ectopic material (gallstones and surgical clips) in the peritoneum.

[Laparoscopic splenectomy due to torsion of a wandering spleen].

Wandering spleen is an uncommon entity, characterized by the anomalous position of the spleen, caused by the absence or laxity of its suspensory ligaments. The most common symptoms are usually due to intermittent or complete torsion of the splenic pedicle with subsequent infarction. We report a case of torsion of a wandering spleen.
