Laparoscopic Internal Marsupializaton for Large Nonparasitic Splenic Cysts: Effective Organ-Preserving Technique

Background Primary splenic cyst is a rare disease, and therefore there is no information regarding its optimal management. Most such cysts are classified as epithelial cysts. During the last few years, the laparoscopic approach has gained increasing acceptance in splenic surgery. We present our experience with the laparoscopic (organ-preserving) management of splenic cysts. Methods We managed 11 patients with large symptomatic nonparasitic splenic cysts from 1996 to 2006. All the patients had fullness in the left upper abdomen and a palpable mass. Preoperative diagnosis was established with ultrasonography and computed tomography. All patients were treated with either laparoscopic partial cystectomy or marsupialization. Results Seven patients had mesothelial cysts, two had epidermoid cysts, and two had pseudocysts. Nine patients did not have any problems or recurrence during an average follow-up of 29.5 months. Two patients had cyst recurrence after 14 months. Conclusion Laparoscopic organ-preserving surgery should be the goal of therapy in most cases. Total splenectomy is reserved for cases in which cyst excision cannot be done or most of the splenic tissue is replaced by the cyst. Plication of the cyst wall edges prevents the cyst walls from adhering and causing recurrence, as well as helping to control hemorrhage. Laparoscopic partial cystectomy/marsupialization is an acceptable procedure for the treatment of splenic cysts; and after short to mid-term follow-up, it seems that a reasonable rate of success is possible.     

Laparoscopic splenic total cystectomy in a patient with elevated CA 19-9.

True nonparasitic splenic cysts are rare. Reports of approximately 30 cases of benign true splenic cysts producing elevated CA 19-9 serum levels have been published. The traditional treatment of splenic epidermoid cysts is splenectomy. However, with all the advances in laparoscopic surgery, conservative laparoscopic approaches are accepted as the most preferred techniques for this benign disease. Laparoscopic cystectomy with its minimal invasiveness and low morbidity is the ideal technique for properly selected patients. So far, only one case report of laparoscopic cystectomy for splenic epidermoid cyst with elevated CA 19-9 levels has been published. This is the second known report of this procedure being performed to remove a splenic epidermoid cyst in a patient with elevated CA 19-9 levels.     

Open and laparoscopic treatment of nonparasitic splenic cysts

BACKGROUND: Nonparasitic splenic cysts are rare. Therefore, there is no 'evidence-based' information regarding their optimal surgical management. In the last years the laparoscopic approach has gained increasing acceptance in splenic surgery. The aim of this study is to present our experience with the laparoscopic management of splenic cysts. METHODS:The medical records of 7 patients with splenic cysts were reviewed retrospectively. RESULTS: One patient had an open partial splenic resection. Five patients, 3 of them with a posttraumatic and 2 with an epidermoid splenic cyst, underwent laparoscopic unroofing of the cyst. In 4 of these cases the postoperative course was uneventful, whereas in 1 case the patient developed a cyst relapse soon postoperatively. Later on this patient successfully underwent an open partial splenic resection. The 7th patient had an explorative laparoscopy. The cyst was located intrasplenically, entirely covered with unaffected splenic parenchyma, and reached the splenic hilus. Therefore, a conversion to open partial splenectomy was performed. CONCLUSION: Open partial splenectomy and laparoscopic cyst wall unroofing are both effective tools in the management of splenic nonparasitic cysts. Surgeons must master both techniques as nowadays spleen-preserving techniques should be attempted in every case of splenic nonparasitic cyst.     

Laparoscopic partial splenectomy using radiofrequency ablation

INTRODUCTION: Epidermoid cysts are believed to be congenital in origin and often present in the pediatric population. Because of the concerns of compromised immunologic function after total splenectomy and increasing demand for minimally invasive approaches, interest has increased in performing the partial splenectomy in this patient population by laparoscopic techniques. Nonetheless, concerns for adequate hemostasis have limited its widespread adoption. Because radiofrequency ablation for the partial splenectomy has been done in a laparoscopic porcine model with good results, we used this technology with the goal of limiting blood loss and postoperative hemorrhagic complications. CASE REPORT: A 25-year-old female presented with complaints of right shoulder pain. Abdominal ultrasound and a computed tomography (CT) scan revealed a 10-cm cystic lesion of the spleen. Serology was negative for hydatid cyst pathology. The patient underwent an uneventful partial splenectomy by minimally invasive techniques with the aid of a laparoscopic radiofrequency ablative device and the placement of a hemostatic medicated sponge along the line of transection. RESULTS: Estimated blood loss was less than 30 mL. Final pathology was consistent with an epidermoid splenic cyst, and the patient was discharged uneventfully on postoperative day 5. DISCUSSION: Techniques for the treatment of symptomatic splenic cysts range from total splenectomy to cyst fenestration and placement of the omentum in the splenic defect. The use of radiofrequency ablation has been traditionally used for hepatic parenchymal transection but seems equally suited for the partial splenectomy. This technology, and the addition of hemostatic sponges, seems to provide excellent results in minimizing blood loss, intraoperatively and postoperatively, during the laparoscopic partial splenectomy; however, randomized, prospective trials will be necessary to see if they will be superior to traditional techniques.     

Hilar localization of splenic cyst does not always exclude the possibility of resective treatment

Non parasitic cysts of the spleen require surgical treatment because of their progressive growth and in order to prevent the potential severe complications associated with such cysts. Since it is now well known that total splenectomy, especially in young patients, has potential for short- and long-term complications, much emphasis has been placed on splenic salvage, suggesting partial splenectomy as procedure of choice for splenic cysts. However various Authors suggest that many but not all splenic cysts can be treated with partial splenectomy. In particular cystic mass arising from the anterior aspect of the hilum near to vascular peduncle contraindicate partial resection requiring splenectomy. In a case observed TC scan demonstrated a very large epidermoid cyst penetrating hilar parenchyma just above splenic vessels insertion. Preoperative imaging suggested splenectomy as the only possible procedure to remove the cyst. At operation the exposure of the splenic artery extended proximally along the pancreatic tail showed an arterial branch running with satellite vein in the splenopancreatic ligament for inferior segment of the spleen. As we found this branch it was possible to resect cyst preserving a large inferior parenchymal segment normally perfused and functioning at postoperative scintigraphic controls. In conclusion not all hilar cysts must be considered an absolute indication to splenectomy. An accurate and extensive exposure of splenic artery and vein can demonstrate vascular anatomical variations permitting resection also for large cysts located near the splenic hilum.     

Laparoscopic marsupialization and hemisplenectomy for splenic cysts

BACKGROUND: Splenic cysts are a rare clinical entity in the United States, and historically, management has consisted of either partial or total splenectomy via an open approach. Laparoscopic treatment of splenic cysts with preservation of splenic parenchyma offers several advantages. Compared with the open approach, a laparoscopic approach may result in less postoperative pain and a more rapid return to full activity. Compared with total splenectomy, splenic preservation eliminates the risk of overwhelming postsplenectomy infection. PATIENTS AND METHODS: We present two patients with splenic cysts. One patient was treated with laparoscopic marsupialization of the cyst and the other with laparoscopic hemisplenectomy. RESULTS: Both patients are without further symptoms at 26 and 5 months' follow-up, respectively. CONCLUSIONS: Laparoscopic marsupialization and hemisplenectomy are appropriate treatment options for patients with splenic cysts.     

Total splenectomy for a recurrent giant splenic cyst

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.     

Posttraumatic Splenic Cysts and Partial Splenectomy: Report of a Case

Nonparasitic splenic cysts are uncommon, with only around 800 cases described in the literature. Posttraumatic splenic pseudocysts constitute most such cases and require surgical treatment when symptomatic or voluminous. Recent studies have provided a better understanding of splenic tissue function and the consequent risks of complete resection of the spleen. Hence surgeons should make every possible effort to preserve splenic tissue. Several spleen-conserving surgical treatments have been proposed, especially for treatment of splenic posttraumatic pseudocysts. The authors report the case of a 13-year-old girl who had a posttraumatic splenic cyst with progressive growth. The diameter of the cyst at surgery was 15 cm, and partial splenectomy was performed. The most common spleen-conserving surgical techniques are briefly reviewed. Received: September 20, 1999 / Accepted: September 26, 2000     

Laparoscopic splenectomy for a huge splenic cyst without preoperative drainage: report of a case

Laparoscopic splenectomy currently is a safe procedure and offers better cosmetic results, less pain, and a shorter hospital stay than the traditional open procedure. However, there have been only a few reports of laparoscopic removal of giant splenic cysts. An 18-year-old woman was admitted with abdominal fullness. CT scans and MRI images of the upper abdomen revealed a cystic mass having a diameter of 19 cm. Preoperative diagnosis was a large splenic cyst, and laparoscopic splenectomy with intraoperative cyst drainage (amount of drained fluid: 3,000 mL) was performed. Histologically, almost the entire cyst wall was lined with fibrous tissue, but a small portion was covered with stratified squamous epithelium. The final diagnosis was epidermoid cyst. The postoperative course was uneventful. Laparoscopic splenectomy should be tried first even in patients with a huge cyst, and intraoperative drainage under laparoscopic guidance facilitates laparoscopic splenectomy.     

The laparoscopic spleen-preserving approach to splenic cysts: advantages and limitations

INTRODUCTION: Due to the multiple functions of the spleen the preferred management of cystic non-parasitic lesions is nowadays laparoscopic partial splenectomy or decapsulation with preservation of the spleen. We have analysed our patients with non-parasitic cystic lesions and the current literature to weigh the benefits and complications of these methods in children and adults. PATIENTS AND METHODS: Laparoscopic partial splenectomy was performed in three children with dysontogenetic cysts. Laparoscopic marsupialisation was performed in one child and in three adults. RESULTS: Follow-up in the true cysts showed no recurrence in one patient and one residual cyst in the second. In the third patient, splenectomy was performed because there was not enough residual spleen to warrant preservation. In the group with post-traumatic cysts, no complications or recurrences were observed. DISCUSSION: The laparoscopic spleen-preserving approach for the treatment of non-parasitic cysts is feasible, but challenging. The main problem is a recurrence rate of more than 20 %. The reason for recurrence remains uncertain: it is probably due to different operative strategies, the morphology of the cysts or the presence of residual cysts. The recurrence rate in post-traumatic cysts is low on the basis of our own experience and a literature survey. CONCLUSION: The benefit of laparoscopic treatment in true non-parasitic splenic cysts has to be weighed against the rate of recurrence. A complete resection of the cysts should be attempted. In post-traumatic cysts, laparoscopy offers a good minimally invasive treatment option.     

Laparoscopic splenectomy for epithelial cyst of the spleen

Splenic cysts of all types are a relatively rare entity. The origin of epithelial cysts of the spleen is controversial, most probably congenital in origin. Generally, epithelial cysts of the spleen are asymptomatic and discovered incidentally. We present the case of a 40-year-old woman with a 3.5 cm splenic cyst diagnosed four years before. The cyst raised progressively in dimension, the actual size being of 6.5 cm. Computed tomography scan and magnetic resonance showed a central splenic cyst in close relations with main splenic vessels. An initial indication of partial splenectomy was established, eventually a total splenectomy being performed by laparoscopy due to close relations of the cyst with the main hilar splenic vessels. The hemostasis was assured with the aid of Ligasure Atlas 10 mm instrument. The pathology examination revealed a multilocular splenic cyst with a cuboidal epithelial lining. Central localization of splenic cysts represents an indication for total splenectomy. Laparoscopy provides a minimal access method of obtaining pathological confirmation of diagnosis, reduction of cyst complications, and a short hospital stay. This article discusses different aspects of epithelial cysts related to pathology, diagnostic and indications for operative treatment, a review of the literature being also presented.     

Laparoscopic management of a ruptured giant epidermoid splenic cyst.

BACKGROUND: Epidermoid splenic cysts are uncommon lesions of the spleen. They are known to become symptomatic as a consequence of enlargement, infection, or rupture, the latter being an exceedingly rare complication traditionally treated with open splenectomy. We herein report a unique case of a giant epidermoid splenic cyst that ruptured spontaneously and was successfully treated with the laparoscopic approach. CONCLUSION: Laparoscopic surgery may be considered an initial treatment option in cases of very large epidermoid cysts even when rupture occurs.     

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.     

Epidermoid splenic cysts and partial splenectomy

We communicate two cases of epidermoid splenic cyst of great size in four and six years old children, with pain in right hypochondrium in one of them, having been casual the discovery of the other one in ultrasound study of the abdomen. In both cases the abdominal ultrasound study was the most useful exploration for its diagnosis. The surgical treatment by means of partial splenectomy and conservation of more than a third of the organ it has been feasible in both patients, with a favorable evolution and without complications. The histopathologic study confirmed the discovery of epidermoid spleen cysts. Later on a clinical, analytic pursuit has been made and of these patients image with a very satisfactory evolution.     

Recurrence after laparoscopic excision of nonparasitic splenic cysts

Background

Minimally invasive treatments for nonparasitic splenic cysts are well described. Recent evidence suggests that laparoscopic splenic cystectomy is associated with high recurrence rates in children. Because these cysts are uncommon, no large series is available. We reviewed our clinical data focusing on cyst recurrences and their management.

Methods

All children who underwent laparoscopic excision of a nonparasitic splenic cyst from January 2002 to December 2006 were identified. Medical and surgical records were reviewed for perioperative details, hospital course, and outcome.

Results

Eight children (median age, 13 years; range, 7-16 years) who underwent laparoscopic splenic cystectomy were identified. The most common presenting complaint was left upper quadrant pain or mass (n = 6; 75%). Median cyst size was 13 cm (range, 4-20 cm). There were no conversions to an open technique, completion splenectomies, or perioperative complications. Cysts were identified pathologically as epidermoid (n = 6) or posttraumatic (n = 2). Median hospital stay was 1.5 days. One child required partial splenectomy because of cyst anatomy and remains recurrence-free at 12 months. Cyst recurrence occurred in 7 patients (88%) at a median of 9.4 months (range, 3-18 months) after initial surgery. Median recurrent cyst size was 5.6 cm (range, 3-11 cm). Of 7 recurrences, 4 (57%) were symptomatic. Percutaneous ultrasound-guided cyst drainage and sclerosis were performed in 2 children with symptomatic recurrences, one of whom required 4 separate interventions. There were no complications during management of cyst recurrences. Five children with recurrence (71%) have been followed conservatively and are free of morbidity at a median of 23 months (range, 8-55 months).

Conclusions

Laparoscopic excision of nonparasitic splenic cysts in children is associated with a high recurrence rate and may be insufficient treatment. Partial splenectomy may decrease recurrence rates. Conservative management of splenic cyst recurrence after laparoscopic excision is associated with good short-term outcomes. If necessary, image-guided management of symptomatic recurrences can be performed safely.     

Partial Splenectomy for Benign Splenic Cysts with the Aid of a Lin Clamp: Technical Note

Background Spleen-preserving procedures deserve every effort by surgeons to reduce the risk of overwhelming postsplenectomy infection. Partial splenectomy at hospitals with restricted sources remains technically demanding. We describe our method of partial splenectomy for benign splenic cysts with the aid of a Lin clamp. Patients and Methods Since April 2003 to August 2004, we have performed partial splenectomy with the aid of a Lin clamp on 5 suitable patients with symptomatic cysts. Detailed patient characteristics, operative variables, and outcomes were collected. Following surgery, they were regularly followed up every 6 months. Results All five partial splenectomies were successfully executed without any complications. The mean operating time was 75 minutes, and a mean operative blood loss of 68 ml could be achieved. With a mean follow-up of 34.4 months, no cyst recurrences were detected to date. Postoperative laboratory data, imaging studies, and clinical situations proved that the preserved splenic parenchyma maintained adequate function. Conclusions Partial splenectomy with the aid of a Lin clamp for benign splenic cysts is a practical method with the advantages of easy application, rapid parenchymal dissection, secure hemostasis, and cost-effectiveness. With encouraging preliminary results, further application of this method to bleeding eccentric parenchymal injuries of the spleen may be warranted.     

Giant epidermoid splenic cyst

Giant epidermoid splenic cysts are rare benign tumors. Their treatment is becoming increasingly less aggressive and more conservative. We report the case of a young woman with a giant epidermoid cyst, which required open total splenectomy, and review the literature on benign congenital tumors of the spleen.     

Long-term outcome after surgical treatment of nonparasitic splenic cysts

Background The optimal treatment for patients with nonparasitic splenic cysts is controversial. This study aimed to evalulate the clinical outcome of patients treated for a symptomatic splenic cyst, and to define a surgical strategy. Methods Spleen-preserving surgery (9 laparotomies and 6 laparoscopies) was performed for a primary cyst in six patients and a secondary cyst in nine patients. The median follow-up time was 37.5 months. Partial splenic resection was performed for eight patients and cyst decapsulation for seven patients. Results Cyst recurrence was observed in four patients after decapsulation of a primary splenic cyst, as compared with none after resection. Postoperative complications were encountered only after laparotomy (5/9). The median hospital stay was 3.5 days (range, 2–5 days) after laparoscopy, as compared with 9 days (range, 5–14 days) after laparotomy. Conclusions Symptomatic splenic cysts should be treated laparoscopically. For patients with recurrent or suspected primary splenic cysts, laparoscopic partial splenectomy is preferable. For other cases, a laparoscopic decapsulation is advocated.     

Laparoscopic partial splenectomies for true splenic cysts. A report of two cases

The goals of treatment for nonparasitic splenic cyst include elimination of the cyst and prevention of recurrence. We treated two cases of true splenic cysts by successfully performing partial splenectomies via a laparoscopic approach. Herein we describe the surgical technique used and tactical aspects. Laparoscopic partial splenectomies can be a definitive treatment for true splenic cysts in that they preserve splenic function and prevent recurrence.     

腹腔镜部分脾切除治疗脾囊肿2例报告并文献复习

脾囊肿相对比较少见,较大囊肿或有压迫症状需外科治疗。传统治疗手段包括脾囊肿开窗引流术和全脾切除术,脾囊肿开窗引流术相对比较简单易行,但术后易出现囊肿复发、积液感染及出血等风险,全脾切除术无复发风险,但破坏患者免疫功能,术后可能出现爆发感染以及静脉血栓;目前认为最理想的治疗方法是行脾部分切除术,既切除病变的脾组织同时也保留了部分健康脾组织,从而保存了脾脏正常的免疫功能。开腹部分脾切除术临床报道较多,但腹腔镜脾部分切除术少见报道。在这里,我们报道两例腹腔镜脾部分切除治疗脾巨大囊肿,术中通过解剖脾门血管,选择性结扎脾上、中极动静脉,在脾缺血带内侧1 cm用超声刀和Hem-o-lok离断脾实质,术后随访无复发。我们认为腹腔镜脾部分切除治疗脾囊肿是安全可行的,具有创伤小、恢复快等优点,值得临床推广应用。
