This study is the largest Italian survey on liver retransplantations (RET). Data report on 167 adult patients who received 2 grafts, 16 who received 3 grafts, and one who received 4 grafts over a 11 yr period. There was no statistically significant difference in graft survival after the first or the second RET (52, 40, and 29% vs 44, 36, and 18% at 1,5,and 10 yr, respectively: Log-Rank test, p = 0.30). Survivals at 1, 5, and 10 years of patients who underwent 2 (n = 151) or 3 (n = 15) RETs, were 65, 48,and 39% vs 59, 44, and 30%, respectively (p = 0.59). Multivariate analysis of survival showed that only the type of graft (whole vs reduced) was associated with a statistically significant difference (HR = 3.77, Wald test p = 0. 05); the donor age appeared to be a relevant factor as well, although the difference was not statistically significant (HR = 1.91, Wald test p = 0.08). Though late RETs have better results on long term survival relative to early RETs, no statistically significant difference can be found in early results, till three years after RET. Considering late first RETs (interval>30 days from previous transplantation) with whole grafts the difference in graft survival in RETs due to HCV recurrence (n = 17) was not significantly different from RETs due to other causes (n = 53) (65–58 and 31% vs 66–57 and 28% respectively at 1–5 and 10 years, p = 0.66).
Progress and changes in the management of blood diseases, in surgery and in video technology stimulate a critical reappraisal of splenectomy in hematology.We have collected information on the current practice of splenectomy in hematology in Italy and we have reviewed the results of a new technique of laparoscopic splenectomy (LS).Current splenectomy practice: the current practice in Italy is to offer splenectomy as front-line treatment for hereditary spherocytosis and as second-line for idiopathic thrombocytopenic purpura (ITP) and hemolytic anemia. Splenectomy is also offered in selected cases of leukemia and lymphoma but is going out of practice for hairy cell leukemia and Hodgkin's disease. The number of splenectomies that are performed every year is estimated to be higher than 10x10(6) persons (more than 500 cases per year). Laparoscopic splenectomy (LS): more than 700 cases of LS have been reported so far, for thrombocytopenia (470 cases) as well as for many other hematologic indications. The procedure carries a mortality of 0.8%, and a complication rate of 12%. Time spent in the operating theater ranges from 1.5 to 4 hours, blood transfusion requirement is minimal and the mean post-operative hospital stay is 3 days.Although a prospective comparison is not available, the results of LS compare favorably with the results of classic open splenectomy, so that LS is likely to become the technique of choice especially when the spleen is small, as in ITP. LS can also have some advantages in other cases of splenectomy, including splenomegaly for leukemia and lymphoma. These data and suggestions should stimulate and renew a discussion about splenectomy in hematology, with the purpose of establishing evidence-based guidelines.
In December 2000, the Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS) was formally launched under the auspices of the Italian Society for Endoscopic Surgery and New Technologies (SICE). The aim of this multicentre study was to analyse various aspects of the treatment that are still under discussion, such as the extension of the laparoscopic indications in cases of malignancy, independently of the associated splenomegaly, patient selection and operative techniques. A retrospective review of 379 patients undergoing laparoscopic splenectomy for haematological diseases from February 1, 1993, to September 15, 2005, was conducted. Data were collected from the 18 italian centres participating in the IRLSS. The mean length of surgery was 140 minutes (range: 25-420). Conversion was necessary in 25 cases (6.6%), and at least one accessory spleen was found in 30 patients (8%). The mean spleen weight was 1200 g (range: 85-4500). Perioperative death occurred in two cases (0.5%). There were no complications in 312 patients (82.3%), with a mean hospital stay of 5.5 days (range: 2-30). Morbidity occurred in 67 patients (17.8%), mainly consisting in transient fever (n = 22), pleural effusions (n = 16), and actual or suspected haemorrhage (n = 14), requiring re-intervention in 7 patients. This first study carried out on the IRLSS data shows that laparoscopic splenectomy may constitute the gold standard for haematological diseases with a normal-sized spleen. The low morbidity and mortality rates suggest that laparoscopic splenectomy can be successfully proposed also for splenomegaly in haematological malignancies.
