Laparoscopic splenectomy for hematologic diseases: a preliminary analysis performed on the Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS).

BACKGROUND: The Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS) was developed to provide at the national level an informative tool useful for performing multicenter studies in the field of spleen laparoscopic surgery. In this first study analyzing the IRLSS data, a cohort of patients with hematologic diseases was retrospectively investigated for potential predictive parameters that could affect the outcome of laparoscopic splenectomy. METHODS: A total of 309 patients who underwent laparoscopic splenectomy for hematologic diseases in 17 Italian centers (between February 1, 1993, and September 30, 2004) were entered in the IRLSS. Their records were analyzed retrospectively by the Student's t-test, chi-square, and logistic regression. RESULTS: The mean operative time was 141 min (range, 30-420 min). Conversion was necessary in 21 cases (7%), and approximately 1 accessory spleen in 25 patients (9%) was found. The mean spleen weight was 1191 g (range, 85-4,500 g). Perioperative death occurred in two cases (0.6%). No complications were experienced by 253 patients (81.9%), who had a mean hospital stay of 5.4 days (range, 2-30 days). Overall morbidity occurred in 56 patients (18.1%), mainly associated with transient fever (n = 22), pleural effusion (n = 13), and actual or suspected hemorrhage (n = 12), requiring a reintervention for 7 patients. Multivariate analysis found that body mass index (p = 0.024) and clinical indication (p = 0.004) were independent predictors for surgical conversion. The clinical indication was almost significant as an independent predictor for the occurrence of postoperative complication (p = 0.05). CONCLUSIONS: This first study analyzing the IRLSS data shows that laparoscopic splenectomy may represent the gold standard treatment for hematologic diseases with normal-size spleen. The low morbidity and mortality rate suggests that laparoscopic splenectomy can be successfully proposed also for splenomegaly in hematologic malignancies.

Potential predictive value of the MELD score for short-term mortality after liver transplantation.

In the last years, a model for end-stage liver disease (MELD) was suggested as a disease severity score for patients with end-stage liver disease awaiting liver transplantation. In the early 2002, United Network for Organ Sharing (UNOS) has proposed to replace the current status 2A, 2B, and 3 by a modified version of the original MELD score based upon patient risk for 3-month mortality on the waiting list. In this study UNOS status and MELD score were evaluated retrospectively for postoperative 3-month mortality in patients who underwent liver transplantation from 2000 to 2001. Liver recipients were stratified for UNOS status 2A, 2B, and 3, and the corresponding MELD score was calculated for each patient. A receiver operating characteristic (ROC) analysis was performed for both conventional UNOS status and MELD score by fitting patient deaths within 3 months after liver transplantation. The MELD score revealed a better prediction rate for 3-month mortality after the first LT than conventional UNOS status, although no statistical significance was evident by ROC curve comparison. This preliminary study seems to suggest a potentially better predictive rate for the MELD score than conventional UNOS status concerning short-term mortality after liver transplantation.

[Total splenectomy for a recurrent giant splenic cyst]. / Splenectomia totale per voluminosa cisti splenica recidiva.

Primary splenic cysts are a rare finding. Some are large and require surgical removal. The Authors report a case of a recurrent huge splenic cyst in a 41-year-old female patient. A marsupialization was performed at another hospital 6 years before. Ultrasonography and computed tomography imaging revealed a cystic lesion in the spleen measuring approximately 20 cm in diameter. A total open splenectomy was performed. Postoperative course was uneventful. The histologic diagnosis was an epithelial cyst of the spleen with no atypical cells in the cyst wall, as previously found at the first operation. The epidermoid cysts have an epidermal lining, and prevention of recurrence is dependent on complete resection of the cyst wall preserving, whenever possible, the splenic tissue. Recurrence can be avoided with partial splenectomy in polar localization of the cyst, or complete removal of the cyst by "peeling" it off the splenic parenchyma. Marsupialization of the cyst, either via a laparoscopic or an open approach, is often ineffective.

[Deep venous thrombosis after leg amputation. Review of the argument]. / La trombosi venosa profonda dopo amputazione degli arti inferiori. Review sull'argomento.

Patients undergoing lower extremity amputation are perceived to be at high risk for deep vein thrombosis (DVT). DVT can cause micro or macro pulmonary embolism and often the post-thrombophlebitic syndrome. The chronic condition can affect patient quality of life and his residual working capacity. Usually the echo-Doppler or the color-Doppler is used as a prevention and diagnostic method, identifying patients at high risk. Following the Authors examine and report the Literature opinion about the topics.

Self-mutilation in a patient with mucolipidosis III.

An 8-year-old girl with mucolipidosis III had self-mutilation of the distal phalanges of the second and third digits of her hands. She had neurophysiologic evidence of carpal tunnel syndrome, and consequent insensitivity to pain, which could explain the self-mutilation. Self-mutilation has not been previously described in lysosomal diseases in which carpal tunnel syndrome is frequently observed.
