目的：观察门静脉高压巨脾大部切除后残脾神经纤维分布与密度变化,评估残脾保留的价值。 方法：选取门静脉高压脾肿大行脾大部切除并残脾腹后固定术患者13例,收集患者术后切取的巨脾组织,以及术后8年穿刺获取的残脾组织,另取外伤性脾组织13例为正常对照。采用免疫组化法检测脾神经肽Y（NPY）和神经丝蛋白200（NF 200）阳性神经纤维分布及密度。 结果：3组脾组织NPY和NF200阳性神经纤维的分布部位大致相同,但两者在巨脾组织中的密度明显较高。红髓部分的定量分析显示,巨脾组织NPY与NF200阳性神经纤维密度均明显高于残脾组织和正常脾组织（均P<0.05）,而两种阳性神经纤维密度在残脾组织与正常脾组织间差异无统计学意义（均P>0.05）。 结论：巨脾大部切除术后残脾神经纤维分布及含量与正常脾大致相同,提示解除高压环境后,残脾神经功能能逐渐恢复正常。     

Partial splenectomy for Gaucher''s disease.

Gaucher's disease is an autosomal recessive disorder caused by deficiency of beta glucocerebrosidase, resulting in an accumulation of glucocerebroside in the reticuloendothelial system. These patients have massive splenomegaly and bone pain, but may have normal life expectancy. Traditionally, splenectomy has been used to treat hypersplenism, but may be associated with a high incidence of postsplenectomy sepsis and accelerated hepatic and bone lipid deposition. Two children are reported who had partial splenectomy for symptoms of Gaucher's disease. Both patients had laboratory evidence of hypersplenism. A 90% splenectomy was performed, and the residual splenic fragment was wrapped in Vicryl mesh. Both patients are currently asymptomatic with normal hematologic parameters. Postoperative radionuclide scans demonstrate increase in the size of the residual splenic fragment. Partial splenectomy may benefit patients with Gaucher's disease, but long-term follow-up care is necessary.     

Partial splenectomy for children with congenital hemolytic anemia and massive splenomegaly

Partial splenectomy is an alternative to total splenectomy for the treatment of congenital hemolytic anemias (CHAs) in children, although the feasibility of this technique in the setting of massive splenomegaly is unknown. This study was designed to evaluate the safety and efficacy of partial splenectomy in children with CHAs and massive splenomegaly. This retrospective study examined 29 children with CHAs who underwent partial splenectomy. Children were divided into 2 groups based on splenic size: 8 children had splenic volumes greater than 500 mL, whereas 21 children had splenic volumes less than 500 mL. Outcome variables included perioperative complications, transfusion requirements, hematocrits, reticulocyte counts, bilirubin levels, splenic sequestration, and splenic regrowth. All 29 children underwent successful partial splenectomy with 0.02 to 10 years of follow-up. After partial splenectomy, children overall had decreased transfusion requirements, increased hematocrits, decreased bilirubin levels, decreased reticulocyte counts, and elimination of splenic sequestration. Children with massive splenomegaly had similar outcomes compared with children without massive splenomegaly. Long-term complications included 3 mild infections, 4 cases of gallstones requiring cholecystectomy, and 1 child who required completion splenectomy. Partial splenectomy is a safe, effective, and technically feasible option for children with various CHAs, even in the setting of massive splenomegaly.     

Elective subtotal splenectomy. Indications and results in 33 patients.

Elective subtotal splenectomy was performed in 33 patients (30 children and 3 adults) between 1981 and 1989. Indications for the procedure were (1) prevention of azathioprine-induced neutropenia (n = 20); (2) Type I Gaucher disease (n = 9); and (3) cholesteryl ester storage disease, chronic myelogenous leukemia, thalassemia major, and splenic cyst in one patient each. There were no operative deaths, no reoperations for bleeding, and 30 of 33 (91%) patients had a functioning splenic remnant documented by a postoperative radionuclide spleen scan. One patient developed neutropenia without evidence of viral infection that required temporary cessation of azathioprine and the patient with thalassemia major had only transient improvement in transfusion requirements. All other patients (94%) had control of the underlying condition for which the operation was performed. We conclude that subtotal splenectomy is a safe, effective therapy for a variety of nontraumatic conditions.     

Laparoscopic subtotal splenectomy

BACKGROUND: Since 1979, we have been studying subtotal splenectomy. This procedure was used in over 200 patients to treat splenic trauma, portal hypertension, myeloid metaplasia due to myelofibrosis, Gaucher disease, chronic lymphocytic leukemia, retarded growth, and sexual development associated with splenomegaly, and disorders of the pancreatic tail. On the basis of our clinic experience with laparoscopic splenectomy with and without splenic autotransplantation, open subtotal splenectomy, and after a training period with laparoscopic conservative splenic operations on animals, this communication presents laparoscopic subtotal splenectomy as a new treatment of severe pain due to ischemia of the spleen. PATIENTS AND METHODS: Two patients with severe splenic pain due to ischemia provoked by vascular obstruction of the spleen were successfully treated by laparoscopic subtotal splenectomy, with preservation of the upper splenic pole supplied only by the gastrosplenic vessels. RESULTS: This procedure was safely conducted with minor bleeding and no technical difficulties or complications. The postoperative follow-up of 5 and 21 months has been uneventful and the pain disappeared since the first postoperative day. CONCLUSIONS: It is feasible and safe to perform subtotal splenectomy by laparoscopy. This procedure seems to be a good treatment for pain due to splenic ischemia.     

Partial splenic decapsulation: a simplified operation for splenic pseudocyst

Splenic pseudocysts have traditionally required splenectomy because of the risks imposed by partial splenectomy or excision of the cyst lining. During the past 2 years, a 6-year-old boy and a 9-year-old girl presenting with vague upper abdominal discomfort, palpable splenomegaly, and a large unilocular sonolucent cyst within the spleen, were treated by partial splenic decapsulation with preservation of the hilar blood supply. This procedure involves mobilizing the spleen by dividing the renal, colic, and diaphragmatic attachments; decompressing the liquefied cyst contents through a thoracostomy trochar; excising the outer splenic capsule and gaining hemostasis of the splenic wall with a running interlocked silk suture; and providing external tube drainage of the left upper quadrant. During the follow-up period of 26 and 12 months, splenic size has returned to normal. Serial nuclear scan and ultrasound show a small residual crescent-shaped deformity of the functioning splenic remnant. We conclude that partial splenic decapsulation for splenic pseudocyst is simpler and safer than other preservation procedures attempted, and carries no increased risk of recurrence from leaving a portion of the pseudocyst wall.     

The ascendance of laparoscopic splenectomy

The application of laparoscopic techniques for abdominal procedures has been achieved with varying success. The general acceptance of laparoscopic splenectomy (LS) may be hindered by its infrequent performance and difficulty in manipulating the spleen. A retrospective review of splenectomies performed for primary splenic pathology was done to assess the role and outcome of LS. One hundred fifty LSs were performed from July 1995 through September 1999. Over that time period the proportion of LS performed increased steadily from 17 to 75 per cent of all splenectomies. The primary indications for splenectomy included immune thrombocytopenic purpura in 75 (50%), lymphoma/leukemia 36 (24%), and splenomegaly 19 (13%). There were 86 females and 64 males. Immediately before operation 36 patients (4%) had a platelet count <50,000/ mL, and 24 patients (16%) a hemoglobin <10 mg per cent. The mean operative time was 161 minutes with an average blood loss of 138 cm3 (<50-800). The mean morcellated weight of the entire group was 411 g (33-3300) indicating generally large splenic size. In the 37 patients with splenomegaly the mean weight was 735 g (293-3300). There were two conversions to open splenectomy. Two patients with hematologic malignancy, splenomegaly, and cytopenias died from overwhelming post-splenectomy sepsis (1.3%). Morbidity occurred in 14 (9%) with the most common complication being pancreatitis in seven (5%). The median length of postoperative stay was 2.4 days (range 1-5). In summary LS has rapidly replaced the open approach for nearly all elective splenectomies in adults and children. When performed with the patient in the lateral position it can be accomplished with minimal morbidity, even in complex patients, including those with splenomegaly.     

Is splenectomy for massive splenomegaly safe in children?

PURPOSE: To study and analyze the causes, etiology, morbidity, mortality and therapeutic value of splenectomy performed for massive splenomegaly in children. METHODS: The medical records of 115 children less than 18 years old who had splenectomy for various hematological disorders were reviewed. Twenty of them had splenectomy for massive splenomegaly (spleen weight > or =1,000 g). The records of these were reviewed for age at operation, gender, hematological diagnosis, indication for splenectomy, operative procedures, postoperative complications, and outcome. RESULTS: Twenty children had splenectomy for massive splenomegaly. There were 16 males and 4 females. Their ages ranged from 4 to 15 years (mean 11.2). Twelve had sickle cell disease, 5 had sickle-beta-thalassemia, 1 had beta-thalassemia major, 1 had thalassemia intermediate, and 1 had chronic myeloid leukemia. The indications for splenectomy were hypersplenism in 11, recurrent splenic sequestration crisis in 8, and splenic abscess in 1. The transfusion requirements in the patient with beta-thalassemia major decreased markedly postoperatively from 18 transfusions/year to only 4 transfusions/year; and for those with hypersplenism, there was a marked improvement in their blood parameters following splenectomy. The patient with thalassemia intermediate required no more blood transfusions. There was no mortality. The immediate postoperative morbidity was 10% for those with massive splenomegaly compared with 6.3% for those with splenomegaly <1,000 g. CONCLUSIONS: With good perioperative management, splenectomy in children with massive splenomegaly is both safe and effective.     

Laparoscopic Partial Splenectomy: Indications and results of a multicenter retrospective study

Introduction Partial splenectomy (PS) in children is a surgical option in haematological diseases and focal splenic tumours. The aim of this study was to describe the feasibility and the results of laparoscopic partial splenectomy in children in these two indications by a multicentric retrospective study. Methods The authors reviewed the files of all children who underwent laparoscopic PS between March 2002 and September 2006 in two paediatric surgical centers. The data of 11 children were collected and included clinical presentation, age, gender, radiographic examinations, surgical procedure, need for blood transfusion and early complications. Results From March 2002 to September 2006, laparoscopic PS had been performed on 11 children (6 boys, 5 girls) aged 23 months to 11 years (mean 7, 9). Four children had splenic focal tumours and seven had haematological diseases: six hereditary spherocytosis (HS) and one hemoglobinosis E. During the surgical procedure for haematological diseases 75–80% of the splenic tissue was removed. When PS was performed for focal splenic tumours, the splenic remnant was around 70%. No preoperative complications occurred (no bleeding, no diaphragmatic injury). Neither preoperative nor conversion was necessary. One postoperative complication occurred (left pleural effusion) but required no further treatment. The mean hospital stay was 7.7 days (range from 3 days to 10 days). No infectious postoperative complications occurred; the mean follow up was 21.1 months (range 3–52 months). Conclusion Laparoscopic partial splenectomy is feasible and safe in children with hypersplenism or focal splenic tumours. Partial splenectomy is a good way to prevent postsplenectomy infections by preservation of the immune role of spleen in children with haematological diseases. This technique performed for focal splenic tumours allows the surgeon to choose the size of the splenic remnant.     

A 27-year experience with splenectomy for Gaucher's disease

Gaucher's disease is an inherited metabolic disorder caused by the defective activity of acid beta-glucosidase and the resultant accumulation of glucosyl ceramide-laden macrophages in the liver, bone, and spleen. Splenectomy is the preferred treatment for patients with Gaucher's disease who develop massive splenomegaly with accompanying hypersplenism and/or mechanical pressure symptoms. The charts of 48 patients with Gaucher's disease undergoing splenectomy at our institution between January 1963 and December 1989 were analyzed to determine the short- and long-term results of this procedure. Thirty-five (73%) patients had total splenectomy, whereas 13 (27%) patients had partial splenectomy. There was one postoperative death (after total splenectomy), and 13 patients (27%) had postoperative complications. Eleven patients (23%) presented with accelerated bone disease after total splenectomy (mean follow-up: 96 months). No patients having partial splenectomy (mean follow-up: 25 months) developed progressive bone disease. Eight patients have died since surgery. All four deaths due to malignant disease occurred in patients after total splenectomy. The results of this largest-ever reported series of splenectomy for Gaucher's disease confirm that while either total or partial splenectomy can be performed with minimal morbidity and mortality, total splenectomy is accompanied by more aggressive bone disease and a predisposition to malignancy. Prospective, randomized trials are needed to substantiate whether partial splenectomy is indeed the treatment of choice for splenomegaly associated with Gaucher's disease.     

Comparison of omental splenic autotransplant to partial splenectomy. Protective effect against septic death

The possible benefit of either partial splenectomy or splenic autotransplantation as protection against post-splenectomy sepsis was investigated. Sprague-Dawley rats were challenged with intravenous Streptococcus pneumoniae and the incidence of bacteremia and mortality were recorded. Animals were divided into four groups based upon the amount of splenic tissue conserved: total splenectomy (0%), partial splenectomy (62%), splenic autotransplantation (27%), or sham celiotomy (100%). A statistically significant (P 0.05) decrease in the incidence of septic death was seen in comparing the total splenectomized animals (63%) to the autotransplant group (27%), the partial splenectomy (4%) and the control group (4%). This diminishing mortality is inversely proportional to the amount of splenic remnant in the respective groups. There was a similar, parallel relationship in the incidence of Streptococcus pneumoniae bacteremia. Thus, the greater the amount of remaining splenic tissue, the lower the incidence of bacteremia and subsequent mortality, implying the preservation of immunologic function with splenic conservation.     

Splenectomy for children with thalassemia

Twenty-three children with thalassemia (18 with beta-thalassemia major, 3 with Hb H disease, and 2 with thalassemia intermediate) had total splenectomy (nine beta-thalassemia major patients and two thalassemia intermediate patients) or partial splenectomy (nine beta-thalassemia patients and three Hb H disease patients) as part of their management at our hospital. There were 10 males and 1 female in the total splenectomy group (mean age, 7.8 years; range, 4.5-12 years), and 4 males and 8 females in the partial splenectomy group (mean age, 6.9 years; range, 3-10 years). In all, the indication for splenectomy was hypersplenism. In the partial splenectomy group, two children with Hb H disease required no further blood transfusions. The transfusion requirements of the third patient with Hb H disease decreased from 15 to 11 transfusions per year (from 1.2 g/week Hb drop preoperatively to 0.7 g/week postoperatively), but subsequently his transfusion requirements increased as a result of an increase in the size of splenic remnant. He underwent total splenectomy 1.5 years post-partial splenectomy. For those with beta-thalassemia major who had partial splenectomy, there was a reduction in the number of blood transfusions from a preoperative mean of 15.2 transfusions per year (range, 11-22 transfusions per year) to a postoperative mean of 8.2 transfusions per year (range, 2-11 transfusions per year). Their Hb drop decreased from a preoperative mean of 1.6 g/week (range, 0.8-3.5 g/week) to a postoperative mean of 0.5 g/week (range, 0.2-0.75 g/week). Subsequently and as a result of increase in the size of splenic remnant, their transfusion requirements increased, but none of them to this point have required total splenectomy. Eleven children had total splenectomy. Their postsplenectomy transfusion requirements decreased from a preoperative mean of 17.8 transfusions per year (range, 12-23 transfusions per year) to a postoperative mean of 10 transfusions per year (range, 8-12 transfusions per year), and their Hb drop decreased from a preoperative mean of 1.8 g/week (range, 0.5-2.3 g/week) to a postoperative mean of 0.45 g/week (range, 0.3-0.65 g/week). In conclusion, total splenectomy is beneficial for children with thalassemia and hypersplenism because it reduces their transfusion requirements. Partial splenectomy may be beneficial for those with Hb H disease. However, for those with beta-thalassemia, partial splenectomy is beneficial in reducing their transfusion requirements only as a temporary measure, and it is recommended for children who are less than 5 years of age.     

Immune function of the upper splenic remnant supplied by short gastric vessels.

OBJECTIVE: To study the immune function of the upper third of the spleen supplied by short gastric vessels after two thirds partial splenectomy. DESIGN: Experimental study. SETTING: Teaching hospital, Turkey. MATERIAL: Sixty Wistar-albino rats, 20 in each group. INTERVENTIONS: Control = sham laparotomy; partial splenectomy = the upper third of the spleen supplied by short gastric vessels was preserved after two thirds partial splenectomy and dividing the main vascular supply; and total splenectomy. At the end of the sixth week postoperatively, antigenic stimulation was induced with an injection of pneumococcal suspension in 10 animals from each group. 0.5 ml of diluted Indian ink was injected into the aorta. MAIN OUTCOME MEASURES: Histological architecture of splenic tissue, and changes in the white pulp after antigenic stimulus. Bacteriological analysis with aerobic blood culture. Phagocytic activity as counted by Indian-ink-laden macrophages. The ability to produce antibodies as measured by serum IgM concentrations. RESULTS: Histological architecture of splenic tissue was normal. Germinal centres (p = 0.02), lymphoid follicles (p = 0.09), and their ratio (p = 0.0006) in the white pulp of the splenic remnant was significantly increased after antigenic stimulus compared with normal spleen. Significantly more animals without spleens developed bacteraemia (p = 0.02). Phagocytic activity of the upper splenic remnant was 89% that of normal spleen. Serum IgM concentrations without antigenic stimulus were 144, 138.2 (p = 0.6), and 86.2 (p < 0.001) mg/L; and with antigenic stimulus 263, 201.7 (p < 0.0001), and 98.1 (p < 0.0001) mg/L in groups 1, 2, and 3, respectively. The increase in serum IgM concentrations as a response to antigen was significant in the control (p < 0.0001) and in the partial splenectomy group (p < 0.0001), but not in the splenectomy group (p = 0.1). CONCLUSIONS: After reduction of its volume, the upper splenic remnant remained adequately supplied by the short gastric vessels. The upper part of the spleen preserved its normal histological architecture, had considerable phagocytic activity, possessed the ability to produce antibodies, and created a satisfactory immune response to antigenic stimulus. In rats, a considerable volume of functional and well perfused splenic tissue is preserved even after dividing the main vessels.     

Laparoscopic versus open pediatric splenectomy for massive splenomegaly

Laparoscopic splenectomy (LS) has rapidly evolved into the technique of choice compared with open splenectomy (OS) because of the advantages of the minimally invasive approach. Splenomegaly increases the technical difficulties of LS. LS for massive splenomegaly has generally been found to fail in adults and children. With improvements in laparoscopic technique and accumulation of laparoscopic experience, however, concerns about completing the procedure in pediatric cases with even massive splenomegaly have been lowered. A retrospective review (April 1997-October 2009) of databases at 2 institutions identified 145 children undergoing splenectomy, 79 laparoscopic and 66 open. We defined splenic margin below the umbilicus or anteriorly extending over the midline as massive splenomegaly. By this definition, 22 cases of pediatric laparoscopic and 17 cases of open splenectomies for massive splenomegaly were performed. Perioperative and follow-up data of laparoscopic pediatric splenectomies were compared with those of open splenectomies, including operative time, bleeding, spleen size, complications, and hospital stay. There were no deaths, wound infections, or instances of pancreatitis. No accessory spleen was missed by laparoscopic; accessory spleens were missed in 2 patients in open splenectomies. The complication rate of laparoscopic versus open was 13.6% versus 41.2%. No subsequent surgery was necessary for dealing with complications both in laparoscopic and open series. Laparoscopic pediatric splenectomy for massive splenomegaly is a feasible, effective, and safe procedure and is associated with low morbidity and a short hospital stay.     

Splenic salvage quantified by uptake of heat-damaged radiolabeled red blood cells. Experimental and clinical studies

We evaluated a noninvasive radionuclide technique to quantify splenic trapping function, which is a key step in the disposition of blood-borne particulates such as poorly opsonized encapsulated microorganisms implicated in hyposplenic fulminant sepsis. Using computerized external gamma imaging, the percentage of splenic uptake of heat-damaged radiolabeled red blood cells was determined in adult Sprague-Dawley rats with eutopic (partial splenectomy) or ectopic (single or multiple autotransplantation) remnants or whole spleens, and in 14 patients with either an intact spleen or splenic remnants after treatment for trauma or hypersplenism. The masses of both eutopic and ectopic remnants correlated directly with the percentage of heat-damaged red blood cell uptake, but the percentage of uptake per gram was higher in eutopic remnants, paralleling more vigorous compensatory growth. In patients, the percentage of heat-damaged red blood cell uptake by remnant spleens was similar to that seen in the rats and, in addition, was supernormal in those with congestive splenomegaly. This noninvasive technique both provides a vivid biplanar image and quantifies blood-borne particle trapping, which is a key splenic function. A heat-damaged red blood cell uptake of less than 15 percent after splenic salvage suggests marginal splenic performance and continued vulnerability to overwhelming sepsis.     

Laparoscopic subtotal splenectomy

AIM: Since 1979, we have studied subtotal splenectomy. This procedure has been used in over 180 patients to treat splenic trauma, portal hypertension, myeloid metaplasia due to myelofibrosis, Gaucher's disease, chronic lymphocytic leukemia, retarded growth and sexual development associated with splenomegaly, and disorders of the pancreatic tail. The aim of this study is to determine the feasibility, reliability and safety of the subtotal splenectomy performed by laparoscopic means. METHODS: An experimental study was conducted in accordance with the International Guiding Principles for Biomedical Research Involving Animals. Fourteen adult mongrel dogs of both sexes were divided into 2 groups (n=7): Group 1 -- laparoscopic subtotal splenectomy, preserving the upper pole supplied by splenogastric vessels; the splenic section, hemostasis and closure was done with a 45 mm linear laparoscopic surgical stapler; Group 2 -- total splenectomy was performed through a median laparotomy. After 3 months, we accomplished hematological, immunological and scintigraphic exams in all animals. Sections of the remnant spleens, livers and lymph nodes were histologically processed. RESULTS: Blood loss was minimal and all animals survived to operation and during the 3 months follow-up. Reduction (p<0.05) of the platelets was verified in Group 1. The rest of the hematological mean values remained normal. The remnant spleens, livers and lymph nodes showed normal histological aspects, with increasing amounts of polymorphonuclear cells observed in both groups. CONCLUSION: It is feasible and safe to perform subtotal splenectomy by laparoscopic means in dog.     

Indications for and results of splenectomy in different hematological disorders

The objective of this retrospective study was to determine the indications for splenectomy in hematological disorders and to analyze the results depending on the indication leading to surgery. Fifty-six patients with various hematological disorders were splenectomized between 1990 and 1994. The main indication was noted. Operative success was defined as: return to normal platelet counts without further medication in thrombocytopenia, relief of pain and local compression syndrome in painful splenomegaly, hemoglobin levels >10 g/dl without the need for further transfusions in hemolytic anemia, response to chemotherapy after splenectomy for prior resistance because of massive splenic infiltration, and relief of infection in splenic infection. Morbidity and mortality were noted. Five major indications for splenectomy were found: thrombocytopenia (n=36, success 78%), painful splenomegaly (n=8, success 100%), hemolytic anemia (n=5, success 60%), resistance to chemotherapy because of massive splenic infiltration (n=5, success 40%), and splenic infection after chemotherapy (n=2, success 100%). One patient with thrombocytopenia died (mortality 2%). Seven patients had major complications (13%). In hematological diseases, thrombocytopenia, painful splenomegaly and splenic infection are likely to be improved by splenectomy. In hemolytic anemia it can be a helpful approach, while in resistance to chemotherapy because of massive splenic infiltration success is less likely.     

Partial splenectomy in Gaucher's disease

In 11 children with hypersplenism due to Gaucher's disease, partial splenectomy was planned with the aim to prevent the development of postsplenectomy sepsis and also to slow the advance of the disease in the rest of the reticuloendothelial system by permitting continuing accumulation of the beta-glucocerebroside in the remaining splenic tissue. In seven children, partial splenectomy was performed successfully, the weight of the splenic tissue removed ranging from 400 to 3,680 g. The postoperative course was uneventful and the average duration of hospitalization was 12 days. In subsequent follow-up, isotope scanning demonstrated continuing growth of the splenic remnant and there were no episodes of postsplenectomy sepsis nor evidence of increased accumulation of beta-glucocerebroside in the liver or bones. These children showed a marked improvement in the growth curve and dramatic improvement in the hematologic picture. Of the four remaining children, in two, partial splenectomy was followed by complete removal of the remaining spleen due to necrosis, whereas in two, total splenectomy was performed since the huge spleens were extensively infarcted. Our experience suggests that partial splenectomy is the treatment of choice in the management of young patients with hypersplenism due to Gaucher's disease.     

Splenomegaly and splenic pseudotumor due to tuberculosis: six new cases

INTRODUCTION: Splenic tuberculosis is rare. The aim of this study was to remind diagnostic problems in this disease, and to evaluate the value of surgery in its management. MATERIAL AND METHODS: Retrospective study of data of six patients (three male and three female, whose mean age was 50 years) admitted in surgical department from 1980 to 2000 for splenic tuberculosis. RESULTS: In six cases, symptoms were poorly specific; splenomegaly and anemia were constant. In imaging studies, splenomegaly was homogeneous in four cases and heterogeneous in two. Diagnosis of tuberculosis was done without need for splenectomy in four patients. Five patients were operated on: two had diagnostic laparotomy without splenectomy, two underwent diagnostic splenectomy and one had splenectomy indicated for splenic abcess refractory to medical treatment. Four of the five operated patients recovered. The two other patients were lost of follow-up. CONCLUSIONS: In our experience, surgery is useful in diagnosis and treatment of splenic tuberculosis.     

Single-port laparoscopic partial splenectomy: a case report

With the better understanding of the importance of the spleen as a primary organ of the human immune system, there has been an increased interest in performing the partial splenectomy for a number of indications such as nonparasitic cysts, benign tumors, staging of lymphomas, etc. Moreover, laparoscopic partial splenectomy has been gaining more interest as the recommended approach for benign splenic disorders to preserve the splenic function with very low recurrence rates. Meanwhile, many surgeons have attempted to reduce the number and size of the ports in laparoscopic surgery with the aim of inducing less parietal trauma and fewer scars. One of these efforts is single-port laparoscopic surgery, which is a rapidly evolving field all over the world. Here, we describe a feasible method of single-port laparoscopic partial splenectomy for treating a benign splenic cyst that was located in the upper medial aspect of the spleen.
