[The relationship between responsiveness to splenectomy and clinical course after splenectomy in chronic idiopathic thrombocytopenic purpura (ITP)].

Fifty-four ITP patients were treated by the protocol proposed by Japanese Idiopathic Disease of Hematopoietic Organ Research Committee. Forty-eight patients were treated with corticosteroid (CS). Twenty-eight patients out of 30 patients who were refractory to CS were splenectomized. To study natural courses of splenectomized patients, 25 patients were splenectomized without elevation of platelet counts at the operation and were followed up their platelet counts and PAIgG for one month without treatment. Clinical courses after splenectomy were classified into four types by the platelet increment followed by splenectomy and the platelet counts at one month after splenectomy; type I (markedly over-shooted platelet peak and normalized platelet counts), type II (moderate platelet peak and 50 approximately 100 x 10(3)/microliters platelets), type III (minimal platelet peak and less than 50 x 10(3)/microliters platelets), and type IV (elevation of platelet counts at day 7 or later of splenectomy and normalized platelet counts). The results of analyses from 25 patients indicated that the numbers of type I, II, III and IV were 10, 5, 6 and 4, respectively. The clinical course of type IV suggests that platelet production may be impaired by anti-platelet antibodies.

High dose intravenous IgG followed by splenectomy versus splenectomy alone in idiopathic thrombocytopenic purpura refractory to steroids.

A total of twenty-six patients with idiopathic thrombocytopenic purpura ITP refractory to corticosteroids were alternately allocated to undergo splenectomy alone (N = 12) or to receive a 5 day course of high dose immunoglobulin G i.v. immediately followed by splenectomy (N = 14). Although there were less initial failures after splenectomy in patients receiving IgG, the proportion of sustained complete remission at 1 and 2 years was identical in both groups. It is concluded that high dose IgG infusions do not improve the results of splenectomy in refractory ITP.

Complications of splenectomy. Comparative study of elective, urgent and incidental splenectomy.

In 160 patients who had undergone elective, urgent or incidental splenectomy, an assessment was made of the possible relationship between the reason for splenectomy and the postoperative course. In patients who had incidental splenectomy, the postoperative complication rate (56.6%), the hospitalization time (20.8 days), and the mortality rate (10%) were higher than among those who had elective or urgent surgery. Our results indicate that splenic injury sustained during abdominal surgery should be treated conservatively, by topical hemostasis or by suturing, in order to avoid complications related to splenectomy.

Laparoscopic splenectomy for treatment of patients with idiopathic thrombocytopenic purpura. Comparison with open splenectomy.

BACKGROUND: Laparoscopic splenectomy (LS) is one of the advanced laparoscopic procedures that benefit most from minimally invasive surgery. This study was undertaken to compare the operating time, blood loss, length of hospital stay, and platelet count response for patients with idiopathic thrombocytopenic purpura (ITP) undergoing open splenectomy (OS) versus LS. METHODS: We performed OS in 20 cases before 1992 and LS in 14 cases after 1993 for the treatment of ITP. RESULTS: The operating time was significantly shorter for OS than for LS (126 +/- 52 min versus 203 +/- 83 min, p < 0.01). Blood loss was less for OS than for LS (321 +/- 264 ml versus 524 +/- 648 ml, p = 0.287). None of the patients who underwent LS were converted to open surgery. Accessory spleens were found in four OS patients (20.0%) and four LS patients (28.6%). The postoperative hospital stay was significantly longer for OS patients than for LS patients (15.2 +/- 5.8 days versus 8.9 +/- 2.9 days, p < 0.0005). No significant difference was noted in the long-term results of splenectomy. CONCLUSIONS: Compared with OS, LS required more operating time, had the potential to cause greater blood loss, had a comparable incidence of accessory spleen and response rate, and appeared to shorten the postoperative stay.

Glucose-6-phosphate dehydrogenase Guadalajara--a case of chronic non-spherocytic haemolytic anaemia responding to splenectomy and the role of splenectomy in this disorder.

Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme of the pentose phosphate shunt pathway a major function of which is to prevent cellular oxidative damage. Deficiency in red blood cells is associated with a number of varied clinical manifestations. Chronic non-spherocytic haemolytic anaemia is uncommon but is usually characterized by chronic haemolysis, often with severe anaemia. In the past splenectomy in this condition has been thought to be of questionable benefit. We report a case of G6PD Guadalajara where splenectomy produced transfusion independence and have reviewed the literature. Those cases with exon 10 mutations often have a severe clinical phenotype, which responds to splenectomy. This procedure should be considered in this condition.

[Primary treatment of hairy cell leukemia with low-dose human recombinant interferon-alpha-2c (Hr-IFn alpha 2c) in comparison with therapy following splenectomy. Interferon (IFn-alpha 2c) in HCL before or after splenectomy].

Within less than 14 months of recruitment 32 centers enrolled 97 patients in a multicenter trial for low-dose treatment of hairy cell leukemia (1.2 X 10(6) IU/m2 X 28 days s.c. with dose reduction according to clinically judged improvement) or ultra-low dose treatment (1.2 X 10(5) IU/m2, s.c. daily increasing to a well-tolerated dose) with Hr IFn-2c (arg). Induction therapy was limited to 84 days. Patients who reached the clinical stage Jansen I or A were then randomized to 2 arms either to receive further IFn (1.2 X 10(6) IU/m2 s.c.) twice a week or to be taken off treatment. For both arms induction therapy was reinstituted whenever a patient lost the criteria of Jansen stage A or I. The study included obligatory central diagnostic procedures and several special investigations. During the first year of the study a special problem evolved in the group of 34 patients with recurrent disease after splenectomy. Ten of them died, 9 of septicemia and 1 of bleeding complications, whereas only 1 death occurred in those patients who received IFn before splenectomy. The risk factors and the response to therapy in the two groups will be analyzed in order to define the criteria that will be needed for the proper choice of primary treatment for HCL. It appears important to us to restrict splenectomy to selected patients.

Hand-assisted laparoscopic splenectomy vs conventional laparoscopic splenectomy in cases of splenomegaly.

HYPOTHESIS: Laparoscopic splenectomy (LS) is the procedure of choice for elective splenectomy. Splenomegaly may preclude safe mobilization and hilar control using conventional laparoscopic techniques. Hand-assisted LS (HALS) may offer the same benefits of minimally invasive surgery for splenomegaly while allowing safe manipulation and splenic dissection. DESIGN: A retrospective review of patients with splenomegaly undergoing conventional LS or HALS was performed. SETTING: Tertiary care referral center. PATIENTS: Hand-assisted LS was performed at the start of the operation for patients with splenomegaly; splenomegaly was determined by palpation of the splenic tip extending to the midline or the iliac crest, or by a craniocaudal splenic length of greater than 22 cm. Splenomegaly was defined as a splenic weight of greater than 700 g after morcellation. MAIN OUTCOME MEASURES: Patient demographic characteristics, operative indications, splenic weight after morcellation, morbidity, mortality, and clinical outcomes were evaluated. RESULTS: Forty-five patients with splenomegaly were identified: 31 underwent standard LS and 14 underwent HALS. The HALS group had significantly larger spleens than the conventional LS group (mean weight, 1516 vs 1031 g; P =.02). Mean operative time (177 vs 186 minutes; P =.89), estimated blood loss (602 vs 376 mL; P =.17), and length of hospital stay (5.4 vs 4.2 days; P =.24) and complication rates (5 [36%] of 14 vs 5 [16%] of 31; P =.70) were similar between the HALS and the standard LS groups. No perioperative mortality occurred. CONCLUSIONS: Hand-assisted LS is a safe and efficacious procedure for these extremely difficult cases. Hand-assisted LS provides the benefits of a minimally invasive approach in cases of splenomegaly.

Splenectomy revised: manually assisted splenectomy with the dexterity device--a feasibility study in 22 patients.

Laparoscopic splenectomy claims a number of advantages over open surgery: less trauma, quicker recovery, and faster return to normal activity. On the other hand, laparoscopic splenectomy is complex and time consuming, and so far, many surgeons are reluctant to perform such an operation. A new device was designed to give manual access to the abdomen through a utility laparotomy. By using one hand in the abdomen during laparoscopy, the surgeon regains direct tactile sense and hand-eye coordination. A pilot study to assess the feasibility of this method has been performed in 22 patients. The operation could be completed easily in 21 patients (95%). The average blood loss was 230 mL, and the average postoperative stay was 3.9 days. With this simple, inexpensive method, it is possible to combine the established convenience, safety, efficacy of open surgery with the advantages of minimally invasive surgery.

[Life-threatening infections after splenectomy--the overwhelming post- splenectomy infection syndrome].

About 2.5% of the patients, on whom splenectomy is done, die later from fulminant bacterial infection. This particular late sequelae usually occurs within 5 years after surgery, however, - especially in adults, - it has been observed also decades after splenectomy. Pneumococci have been identified as infectious agents in about 70% of the cases concerned. This syndrome is caused by deficient clearance of bacteria, which is due to reduced phagocytosis, decreased IgM-production, disturbances of the complement system and lack of tuftsin. Prevention of this syndrome may be achieved by using surgical procedures saving part of the spleen, by appropriate use of antibiotics and by vaccination against pneumococci.

[Splenorrhaphy and partial splenectomy as an alternative to splenectomy in trauma--overview].

For many year splenectomy was considered to be the only possible surgical treatment for all laceration of the spleen, whether resulting from abdominal contusion or not. Such factors have led to changes in practical attitudes to splenic lacerations but it would seem that indications for a conservative approach must be based upon the underlaying condition and the precise nature of the lesions. Splenectomy should be done promptly in cases of concomitant splenic and cerebral injury and in patients with injury of multiple organ systems. Present knowledge of the complications of anesplenia has led to new surgical techniques for conservation of splenic tissue. Splenorrhaphy was a frequently used treatment in the non-complicated traumatic lesions. The decision of whether or not to remove an injured spleen is one which must be made intraoperatively by the surgeon. Operative splenic repair and preservation of the spleen often requires considerable experience. We conclude that surgical splenic preservation is a viable and safe procedure, especially in infants and young children.

[Favorable effect of splenectomy on anemia in 3 siblings with type II congenital dyserythropoietic anemia (HEMPAS). (Ultrastructural changes in erythrocytes after splenectomy)].

Congenital dyserythropoietic anemia type II (CDA-type II) (HEMPAS) was reported in three siblings. CDA-type II was associated with marked hepatosplenomegaly and siderosis of both organs. All three sibling developed cholelithiasis with choledocholithiasis and obstructive jaundice in two of them. Anemia showing hemolytic component with sequestration of erythrocytes in the spleen was corrected after splenectomy without the need of blood transfusions during the follow up period of 20, 11 and 11 years. Ultrastructural investigation of the erythrocytes after splenectomy revealed increased number of erythrocytes showing the double membrane phenomenon.

Hand-assisted laparoscopic splenectomy (HALS) in cases of splenomegaly: a comparison analysis with conventional laparoscopic splenectomy.

BACKGROUND: Laparoscopic splenectomy (LS) is considerably more difficult to perform when the spleen is enlarged. The new technique of hand-assisted designed technique aimed to assist laparoscopic surgery allows the surgeon to insert his or her hand into the abdomen while maintaining the pneumoperitoneum, thus recovering the tactile sensation lost in conventional laparoscopic surgery. OBJECT: In this study, we compared the immediate results of conventional LS and hand-assisted LS (HALS) in cases of splenomegaly. METHODS: Between February 1993 and August 2001, 200 LS were attempted at two university hospitals. In 56 cases, splenomegaly (final spleen weight >700 g) was observed clinically or detected on radiological examination. We compared the first 36 patients operated on by conventional LS (group I) with the last consecutive 20 patients, who underwent HALS (group II). The study parameters were operative time, conversion rate, transfusion rate, morbidity and length of hospital stay. RESULTS: The groups were comparable in terms of age (58 +/- 13 [ranges, l9-82] vs 58 +/- 16 years [range, 44-84] (ns), diagnosis, and spleen weight (1425 +/- 884 [range, 700-3400]) vs 1753 +/- 1124 g [range, 720-4500] (ns). HALS was associated with less morbidity (36% vs 10%) (ns), a shorter operative time (177 +/- 52 [range, 95-300]) vs 135 +/- 53 min [range, 85-270] (p <0.009), and a shorter hospital stay (6.3 +/- 3.3 [range, 3-14]) vs 4 +/- 1.2 [range, 2-7] days (p <0.05). CONCLUSION: In cases of splenomegaly, HALS assisted laparoscopic surgery significantly facilitates the surgical maneuvers during LS while maintaining the advantages of a purely laparoscopic approach.
