A 37-year-old man was referred for massive splenomegaly. In November 2005, he was diagnosed with non-Hodgkin's B-cell lymphoma in the setting of splenomegaly and thrombocytopenia. His laboratory results showed a coagulopathy owing to lupus anticoagulant. A computed tomography scan showed a 36 x 26 x 11 cm spleen and a prominent and sinuous splenic artery. The authors performed a laparoscopic splenectomy with an initial ligation of the splenic artery. The patient tolerated the procedure well and was discharged home on the fourth postoperative day in stable condition. Discussed in this paper is the safety and feasibility of the minimally invasive approach in massive splenomegaly.  相似文献

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.  相似文献

Laparoscopic splenectomy: size matters   总被引:5,自引:0,他引:5  
BACKGROUND: Laparoscopic surgery is arguably the treatment of choice for patients undergoing elective splenectomy; however, for those patients with massive splenomegaly, laparoscopic surgery may prove difficult. PATIENTS AND METHODS: 6 years' experience of elective splenectomy was reviewed, in particular looking at the outcome of laparoscopic splenectomy in relation to the degree of splenomegaly. RESULTS: The conversion rate for laparoscopic splenectomy on patients with spleens weighing less than 1 kg was 0% whereas the conversion rate for those with spleens weighing more than 1 kg was 60%. In addition, a good correlation between both operative time and intra-operative blood loss in relation to splenic weight was observed. Open splenectomy on patients with spleens weighing more than 1 kg reduced the operative time and intra-operative blood loss without affecting hospital stay. CONCLUSIONS: Laparoscopic splenectomy is the method of choice for elective splenectomy in patients with splenic weight estimated to be < 1 kg; however, the operation takes longer, there is a high risk of conversion and there is an increase in blood loss/morbidity associated with massive splenomegaly (spleen > 1 kg) if splenectomy is attempted laparoscopically.  相似文献

Hand-assisted laparoscopic splenectomy for giant spleens   总被引:5,自引:0,他引:5  
BACKGROUND: Laparoscopic splenectomy for massive splenomegaly is technically difficult, and the morcellated splenic tissue may be inadequate for histologic study. A hand-assisted technique may provide a technical advantage and allow removal of larger pieces of spleen. METHODS: Patients who underwent hand-assisted laparoscopic splenectomy for massive splenomegaly were reviewed. Demographic information, operative data, and outcomes data were tabulated. RESULTS: Sixteen patients met these criteria. Mean age was 56 years (range, 35-78 years). Operating time averaged 240 min (range, 165-360 min), and median blood loss was 425 cc (range, 100-1800 cc). There were no conversions to an open procedure. Mean weight of extracted spleens was 2008 g (range, 543-4090 g). Postoperative length of stay averaged 3.3 days (range, 2-7 days). There was one postoperative complication (6.25%) and no mortality. CONCLUSIONS: Hand-assisted laparoscopic splenectomy for massive splenomegaly is feasible and safe while preserving the recovery benefits of minimal access surgery. It provides an adequate specimen for histologic study.  相似文献

巨脾切除术的技术要点   总被引:1,自引:0,他引:1  
The spleen whose size reaches or exceeds third degree should be regarded as massive splenomegaly.Splenectomy for massive splenomegaly demands precise procedures.First,median incision on upper abdomen(or vertical rectus muscle splitting incision)and incision under left costal arch are preferred.Second,the spleen was freed and then 0.33 mg of epinephrine was injected via the splenic artery before splenic artery ligation.During the process,a cell saver helps to minimize blood loss and makes autoinfusion possible for patients with benign lesions.Third,preoperative administration of fibrinogen,platelet and essential styptieum combined with the cooperation between surgeons and anesthesi010gists are the key points of bloodless surgery which is important for the recovery of patients.Four common problems of splenectomy for massive splenomegaly should also be addressed,including operation discontinuance,perioperative hemorrhage,accessory injury and postoperative intractable fever.  相似文献

We report the rare case of a splenic inflammatory pseudotumor associated with massive splenomegaly, diagnosed after surgery. A 51-year-old woman was admitted to our hospital for investigation of anemia. Physical examination revealed a palpable left upper quadrant mass. Computed tomography and magnetic resonance imaging showed a splenic mass, 20 cm in diameter. We performed splenectomy for both diagnosis and treatment. The spleen weighed 2400 g, and histologic examination of the mass confirmed an inflammatory pseudotumor. Portal vein thrombosis (PVT) developed the day after surgery, but resolved with anticoagulation therapy. This case highlights that there is a risk of PVT after splenectomy in patients with massive splenomegaly, and that anticoagulant therapy should be initiated promptly.  相似文献

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.  相似文献

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.  相似文献

Laparoscopically assisted splenectomy with an 8- to 10-cm left upper paramedian laparotomy was performed following preoperative splenic artery embolization using painless contour emboli (super absorbent polymer microsphere) with early successful results in two men (46 and 37 years old) with myelofibrosis accompanied by massive splenomegaly. Dissection around the lower part of the spleen and the hilum initially was performed intracorporeally with the usual laparoscopic view under 12 mm Hg pneumoperitoneum. The alternating changes of viewpoints between the direct view through an 8- to 10-cm incision and the usual laparoscopic view with or without application of a retraction method were effective for safe hilar devascularization. Preoperative splenic artery embolization at the distal site was effective for safe dissection around the enlarged spleen. The patients did not complain of pain before operation. Preoperative painless embolization and laparoscopically assisted splenectomy with small laparotomy promotes the feasibility and safety of minimally invasive splenectomy for myelofibrosis with massive splenomegaly.  相似文献

We evaluated outcomes of endovascular treatment of splenic artery aneurysms and pseudoaneurysms. From April 2002 to May 2007, 17 patients (mean age 55.2 years, range 17-82) with splenic artery aneurysms (n = 7) or pseudoaneurysms (n = 10) underwent endovascular treatment. Six patients were asymptomatic, three had symptomatic nonruptured aneurysms, and eight had ruptured aneurysms. Lesions were in the proximal splenic artery (n = 5), intermediate splenic artery (n = 3), splenic hilum (n = 6), or parenchyma (n = 3). Embolization was with microcoils by sac packing (n = 8), sandwich occlusion of the main splenic artery (n = 4), or cyanoacrylate glue into the feeding artery (n = 4). Computed angiotomography was done within the first month and magnetic resonance angiography after 6 and 12 months, then yearly. Mean follow-up was 29 months (range 1-62). Exclusion of the aneurysm was achieved in 16 (94.1%) patients. One patient with an intraparenchymal pseudoaneurysm underwent splenectomy after failed distal catheterization. No major complications occurred. Postembolization syndrome developed in four patients, who had radiographic evidence of splenic microinfarcts. Transcatheter embolization of splenic artery aneurysms/pseudoaneurysms is safe and effective and may induce less morbidity than open surgery, in particular by preserving the spleen. Coil artifacts may make magnetic resonance angiography preferable over computed tomography for follow-up.  相似文献

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.  相似文献

Splenectomy for massive splenomegaly   总被引:2,自引:0,他引:2  
Splenectomy was performed on 47 patients with massive splenomegaly (spleen weight greater than 1.5 kg). With one exception, all patients had a haematological malignancy. The indications for splenectomy were for the diagnosis of unknown cause (n = 5), for the relief of pain (n = 8), as the initial treatment of hairy cell or prolymphocytic leukaemia (n = 8), and for the correction of a haematological cytopenia (n = 26). Splenectomy was completely successful in relieving pain and in establishing a diagnosis, and provided effective palliation in patients with hairy cell and prolymphocytic leukaemia. An immediate correction of a haematological cytopenia was achieved in 24 patients, and the correction was maintained for over 1 year in 11 patients. There were no postoperative deaths and morbidity was acceptably low. We conclude that patients with massive splenomegaly can derive considerable benefit from splenectomy and that massive splenomegaly should not be regarded as a contra-indication to splenectomy.  相似文献

BACKGROUND: Despite the benefits of the laparoscopic approach to splenectomy, its application in patients with massive splenomegaly (splenic weight >or= 1000 g) remains controversial. In this study we evaluated the safety and feasibility of laparoscopic splenectomy for massive splenomegaly compared with open splenectomy. MATERIALS AND METHODS: One surgeon applied the laparoscopic approach to splenectomy to all comers with massive splenomegaly, while other surgeons carried out the surgery through a laparotomy. The outcomes of the two approaches were compared on an intention-to-treat basis. Results of continuous variables are shown as medians. RESULTS: Fifteen patients underwent laparoscopic splenectomy between 2000 and 2005, and 13 underwent open splenectomy between 1996 and 2003. The two groups were comparable for age, sex, American Society of Anesthesiologists score, and splenic weight (1.3 vs. 1.1 kg). There was one conversion (6.6%) to open surgery. Although laparoscopic splenectomy was associated with significantly longer operating time (175 vs. 90 minutes, P < 0.001), it carried lower postoperative morbidity and mortality (13.3 vs. 30.8% and 0 vs. 7.7%, respectively). Laparoscopic splenectomy was associated with significantly lower total dose (29 vs. 264 mg morphine-equivalent, P < 0.0001) and duration of opiate usage (1 vs. 4 days, P < 0.0001); duration of parenteral hydration (24 vs. 96 hours, P = 0.006) and more rapid resumption of oral diet (24 vs. 72 hours, P = 0.017); and a shorter postoperative hospital stay (3 vs. 10 days, P < 0.0001). CONCLUSIONS: The laparoscopic approach to splenectomy for massive splenomegaly is feasible and safe. Despite a longer operating time, the postoperative recovery following laparoscopic splenectomy is smoother, with lower morbidity and shorter postoperative hospital stay compared with open splenectomy.  相似文献

The etiology of Klippel–Trenaunay syndrome (KTS) is not well understood. Although splenic involvement is very rare in KTS, life-threatening events such as spontaneous rupture of a splenic hemangioma may occur. We recently performed elective splenectomy for massive splenomegaly causing uncontrollable abdominal pain in a woman with KTS. The extracted spleen weighed 4260 g, and cavernous hemangiomas in the spleen were found to be the cause of the splenomegaly. The patient’s abdominal pain resolved after surgery and her postoperative course was uneventful, except for persistent bleeding from the bladder. This is a rare case of KTS with associated severe splenomegaly caused by hemangiomas.  相似文献

Laparoscopic splenectomy for massive splenomegaly   总被引:23,自引:0,他引:23  
BACKGROUND: Laparoscopic splenectomy (LS) is the preferred operative approach for diseases involving normal-sized spleens. Our experience with laparoscopic splenectomy in the setting of massive splenomegaly is presented. METHODS: A prospective review of patients undergoing LS for massive splenomegaly was conducted. Massive splenomegaly (MS) in adults was defined as a craniocaudal length >or=17 cm or a morcellated weight >or=600 g. In children, spleens measuring fourfold larger than normal for age were considered massive. RESULTS: Forty-nine patients with MS were treated with LS. The most common primary diagnoses were lymphoma and leukemia. Mean splenic length was 20 cm (15 to 27 cm), with weights ranging from 600 to 4,750 g. Twelve patients with supermassive splenomegaly (length >22 cm) required a hand-assisted laparoscopic approach. There were no conversions to open surgery. Mean operating time was 171 minutes (90 to 369). Mean blood loss was 114 cc (<30 to 600 cc). Average length of stay was 2.3 days (1 to 16). Minor postoperative complications occurred in 3 patients. CONCLUSIONS: Laparoscopic splenectomy in the setting of splenomegaly is safe and appears to minimize perioperative morbidity. In patients with supermassive splenomegaly, a hand-assisted laparoscopic approach may be required.  相似文献

Splenectomy for massive splenomegaly is frequently performed for hematologic disorders for diagnostic and therapeutic indications. The role of splenectomy is complex and controversial. The aims of our retrospective study were to focus on postoperative complications and advantages of splenectomy for massive splenomegaly. Thirty six patients with splenomegaly weighing 1000 g or more, underwent splenectomy at Centre Hospitalier Universitaire Lyon Sud, from January 1st, 1982, to December 31, 1995. Thirty-one (85%) of these patients had hematologic malignancy and more than half of them were older than sixty years. The main indications for splenectomy were hypersplenism (18 patients) and diagnosis (14). Preliminary ligation of the splenic artery was performed in 25 patients (42%). All patients had drainage. The mortality and morbidity rates were 5.5% and 20%, respectively. No major septic or thromboembolic complications occurred. There was only one major bleeding complication. The advantages of splenectomy included histopathological diagnosis in 13 of 14 patients with splenomegaly of unknown origin, permanent pain relief in all cases, and immediate correction of hematological cytopenia in 27 cases (75%). We conclude that the large weight of the spleen does not constitute a contraindication to splenectomy, but indications must be carefully selected, and the operative and perioperative management, must be appropriate.  相似文献

Background

Although laparoscopic splenectomy has been gradually regarded as an acceptable therapeutic approach for patients with massive splenomegaly, intraoperative blood loss remains an important complication. In an effort to evaluate the most effective and safe treatment of splenomegaly, we compared three methods of surgery for treating splenomegaly, including open splenectomy, laparoscopic splenectomy, and a combination of preoperative splenic artery embolization plus laparoscopic splenectomy.

Methods

From January 2006 to August 2011, 79 patients underwent splenectomy in our hospital. Of them, 20 patients underwent a combined treatment of preoperative splenic artery embolization and laparoscopic splenectomy (group 1), 30 patients had laparoscopic splenectomy alone (group 2), and 29 patients underwent open splenectomy (group 3). Patients’ demographics, perioperative data, clinical outcome, and hematological changes were analyzed.

Results

Preoperative splenic artery embolization plus laparoscopic splenectomy was successfully performed in all patients in group 1. One patient in group 2 required an intraoperative conversion to traditional open splenectomy because of severe blood loss. Compared with group 2, significantly shorter operating time, less intraoperative blood loss, and shorter postoperative hospital stay were noted in group 1. No marked significant differences in postoperative complications of either group were observed. Compared with group 3, group 1 had less intraoperative blood loss, shorter postoperative stay, and fewer complications. No significant differences were found in operating time. There was a marked increase in platelet count and white blood count in both groups during the follow-up period.

Conclusions

Preoperative splenic artery embolization with laparoscopic splenectomy reduced the operating time and decreased intraoperative blood loss when compared with laparoscopic splenectomy alone or open splenectomy. Splenic artery embolization is a useful intraoperative adjunctive procedure for patients with splenomegaly because of the benefit of perioperative outcomes.  相似文献

OBJECTIVE: To evaluate the impact of spleen weight on operative and clinical outcome in a series of 108 consecutive laparoscopic splenectomies. BACKGROUND: Laparoscopic splenectomy as an alternative to open splenectomy for splenomegaly is regarded as controversial. METHODS: Patients underwent laparoscopic splenectomy for a range of hematological disorders between November 1992 and February 2000. Multiple linear and logistic regression analysis were used to assess the effect of massive splenomegaly (>1000 g) on perioperative mortality and morbidity, after adjusting for the joint effects of patient age, weight, pre- and postoperative full blood counts, operating time, estimated blood loss, conversion rate, reoperation rate, and duration of hospital stay. RESULTS: Massive splenomegaly was recorded in 27 of 108 (25%) cases. In this group, splenic weight ranged from 1000 to 4750 g (median, 2500 g). Patients with splenic weight >1000 g had a significantly longer median operating time (170 vs. 102 minutes, P < 0.01), conversion rate (5/27 vs. 4/81, P < 0.05), postoperative morbidity (15/27 vs. 4/81, P < 0.01), and median postoperative stay (5 vs. 3 days, P < 0.01). Multivariate analysis found splenic weight to be the most powerful predictor of morbidity (P < 0.01). Patients with splenomegaly (>1000 g) were 14 times likely to have post operative complications. One patient died 3 days after surgery, following a pulmonary embolus (spleen weight 500 g, mortality 1/108, 0.9%). CONCLUSIONS: Laparoscopic splenectomy is feasible in patients with giant spleens. However, it is associated with greater morbidity, and the advantages of minimal access surgery in this subgroup of patients are not so clear.  相似文献

Background  

Laparoscopic splenectomy (LS) has become a safe and feasible procedure for cases involving spleens of normal size. Only a few publications report on the outcome of LS with preoperative splenic artery embolization (SAE) for massive splenomegaly. The authors present their experience in patients with massive splenomegaly who underwent laparoscopic-assisted splenectomy (LAS) or hand-assisted laparoscopic splenectomy (HALS) following SAE.  相似文献
