Introduction: the finding of the vermiform appendix within a crural hernia (Amyand's hernia) is a rare entity whose incidence is not described in the literature. Objective: the aim of this study was to report our hospital's experience in this kind of pathology. Material and methods: between 1993 and 2004, 4,572 acute appendicitis and 372 incarcerated crural hernia cases have been operated on in our hospital. We studied 6 cases of incarcerated crural hernia with vermiform appendix inside. We analyzed in retrospect the following parameters: age, sex, personal history, clinical manifestations, preoperative diagnosis, surgical technique, mean hospital stay, and outcome. Results: all patients were women with a mean age of 78.8 years. Most frequent clinical manifestations included pain and a mass in the right inguinocrural region, of variable intensity and duration. No clinical, laboratory, or radiographic signs help in reaching a correct preoperative diagnosis. General anesthesia and a crural approach are used in most surgical operations. In all cases an appendectomy was performed via the hernia sac, thus proving the presence of acute appendicitis in four of them (66.67%). A prosthetic mesh was used in 3 cases, and one case of wound infection was found. In the other cases we sutured the hernia ring using prolene. Conclusion: the finding of the appendix in an incarcerated crural hernia is a rare entity in old women that is difficult to diagnose preoperatively. Treatment includes appendectomy and herniorraphy. The use of prosthetic mesh is controversial.

Introduction: leiomyoma is the most common benign esophageal neoplasm. Surgical treatment (enucleation) has traditionally been the therapy of choice. The advent of minimally invasive techniques has produced an increase in endoscopic approaches to the detriment of open surgery. Objective: the aim of this study was to compare the results obtained with open surgery and with laparoscopic surgery in this kind of pathology. Material and methods: we performed a retrospective study of all leiomyomas operated for in our center between 1986 and 2004, and obtained 9 cases of esophageal leiomyoma. Four were women and five men, between the ages of 40 and 70, with a mean age of 53.5 years. The most frequent symptoms were heartburn (5 cases), dysphagia (3 cases), and retrosternal pain (3 cases). Surgery was in all the cases an enucleation. An open approach was performed in 5 cases (3 thoracotomies and 2 laparotomies), and an endoscopic approach in 4 (2 thoracoscopies and 2 laparoscopies). Results: the mean postoperative hospital stay was 5.12 days (range 2-8 days). This was shorter for endoscopic approaches versus open surgery (3.25 vs. 7 days). There was no case of esophageal mucosal perforation or reconversion. No death, intraoperative complication, or tumor relapse was described. Only 2 patients had complications: post-surgical thoracic pain, and intestinal obstruction by adhesions 8 years after surgery. Conclusion: enucleation is an easier procedure and constitutes the therapy of choice for esophageal leiomyoma. This approach has to be laparoscopic. We think that muscle borders should be closed after enucleation, and that biopsy is not indicated preoperatively.

Littoral cell angiomas (LCAs) are rare splenic vascular neoplasms that arise from the cells lining the red pulp sinuses. The clinical course is benign and in most cases asymptomatic. However, as has been described in the literature, we have seen an association with malignant neoplasms and haematological disorders. The definitive diagnosis is made on histology and confirmed with immunohistochemistry. The use of percutaneous fine-needle aspiration biopsy (FNA) in preoperative diagnosis is controversial.

radical surgery is associated with lower morbidity, mortality, postoperative hospital stay, and recurrence rates, and represents the treatment of choice for hepatic hydatidosis. However, its indication must depend on the patient characteristics, cyst anatomy, and surgical team experience.
