Laparoscopic partial splenectomy

Minimally invasive spleen-preserving surgery to treat primary splenic hydatidosis: short and long-term outcomes: a cohort study

Background

Primary splenic hydatidosis, a rare manifestation of Echinococcus granulosus infection, presents unique diagnostic and therapeutic challenges. This study compares spleen-preserving surgeries with total splenectomy for treating primary splenic hydatid cysts, focusing on short- and long-term outcomes in the Jordanian context, a region particularly affected by this condition.

Methods

This retrospective analysis was conducted on 18 patients diagnosed with primary splenic hydatid cysts at two Jordanian hospitals from January 2015 to June 2021. Selection criteria included confirmed diagnosis and complete medical records. Surgical approaches, including laparoscopic partial splenectomy, cystectomy, and cyst deroofing, supplemented by albendazole therapy, were compared based on patient demographics, symptoms, surgical details, complications, and recurrence rates.

Results

The study group was composed of (n=7, 38.9%) male and (n=11, 61.1%) female patients, with an average age of 33.7 years. Most presented with left upper quadrant pain. Postoperative complications occurred in 22% of patients, with an 11% recurrence rate during follow-up. No significant statistical difference in recurrence rates was observed between spleen-preserving surgeries and total splenectomy. These findings highlight the efficacy of less invasive, spleen-preserving techniques in managing primary splenic hydatidosis, showing comparable outcomes to total splenectomy with minimal impact on recurrence rates.

Conclusion

Spleen-preserving surgery offers a viable alternative to total splenectomy in treating primary splenic hydatid cysts. This approach maintains immune functionality and reduces septic risks, especially in pediatric patients. The study underscores the importance of individualized treatment approaches and suggests further research with larger cohorts for more comprehensive insights into managing this rare condition. The limitations of this study include its small sample size and retrospective nature.

Laparoscopic partial splenectomy for a giant splenic pseudocyst with elevated CA19-9: a case report

Introduction and importance

Currently, there is a lack of reliable evidence on the management of splenic cysts, which are rare. Exploring the efficacy of laparoscopic partial splenectomy can aid in the accumulation of treatment-related evidence.

Case presentation

Here, we report the case of a 31-year-old female who was diagnosed with a giant splenic cyst with elevated serum CA19-9 and subsequently underwent laparoscopic partial splenectomy.

Clinical discussion

The effects of most treatment options for splenic cysts, including percutaneous aspiration and drainage, fenestration, and partial splenectomy, have not been confirmed by high-level evidence. With the development of minimally invasive surgery, laparoscopic partial splenectomy has drawn increasing attention. Additionally, the relationships between tumor markers and splenic cysts need to be further elucidated.

Conclusions

Laparoscopic partial splenectomy might be recommended for patients with splenic cysts, especially when the cysts are not completely covered by the splenic parenchyma.

Robot-assisted resection of benign splenic tumors in children

PURPOSE

Robotic surgery is becoming increasingly widely used in the field of pediatric surgery. The present study aimed to evaluate the safety and feasibility of robot-assisted resection of benign pediatric splenic tumors and to discuss the technical points.

METHODS

A total of 32 patients who were diagnosed with benign splenic tumors and underwent minimally invasive surgery from January 2017 to September 2023 were included in the study. The clinical data including demographic criteria, operative details, and postoperative outcomes were analyzed retrospectively.

RESULTS

Thirteen patients underwent robot-assisted surgery, and 19 patients underwent laparoscopic surgery. The median operation time was 150 min, with an interquartile range (IQR) of 120 to 200 min for the robot-assisted group and 140 min with an IQR of 105 to 180 min in the laparoscopic group (P = 0.318). Despite four cases in the laparoscopic group (21%) being converted to laparotomy because of intraoperative bleeding, compared with none in the robot-assisted group, there was no significant difference between two groups (P = 0.128). The intraoperative volume of blood loss was significantly less (P = 0.041), and the hospitalization expense was significantly higher (P = 0.000) in the robot-assisted group than for the laparoscopic group. There was no significant difference in patients' age, tumor size, postoperative feeding time, and the postoperative hospitalization time between two groups (P > 0.05).

CONCLUSION

Robot-assisted benign splenic tumor resection was safe and feasible, and it reduced surgical trauma for the pediatric patient.

Sigmoid colon perforation with splenic abscess due to ulcerative colitis: A case report and review of the literature

INTRODUCTION AND IMPORTANCE

The occurrence of abscesses in the spleen, a substantial abdominal organ with hematopoietic function, is relatively rare in clinical cases and mostly occurs in immunodeficient populations. The early symptoms of splenic abscess are not obvious, and the diagnosis is usually confirmed by a combination of patient symptoms, imaging manifestations and blood culture results.

CASE PRESENTATION

A 36-year-old male patient was treated in the emergency room for severe lower abdominal pain and discomfort. An abdominal CT(Computed Tomography) examination initially suggested an acute bowel perforation and an enlarged and abnormally thick spleen. The patient first underwent a repair of the bowel perforation, which was followed by fever and no reduction in abdominal symptoms, while the patient's splenic abscess was then treated with a repeat splenectomy.

CLINICAL DISCUSSION

Splenic abscesses mostly occur in immunocompromised patients. The treatment of splenic abscesses includes simple antibacterial medication, percutaneous puncture placement for drainage, and splenectomy for drainage. In our case, the treatment of this patient's splenic abscess was divided into several stages, and we finally used splenectomy for drainage because the patient's symptoms were not significantly better than before and combined with coagulation abnormalities.

CONCLUSION

In patients with severe abdominal infection and relevant ancillary tests suggesting abnormal spleen size and density, it is also important to consider whether a splenic abscess has formed and to provide early diagnosis and treatment of splenic abscess while fighting abdominal infection.

Laparoscopic partial splenectomy for symptomatic benign cystic lesions: technical notes

The purpose of this study was to explore the feasibility of laparoscopic partial splenectomy in patients with symptomatic benign lesions. During the period from April 2017 to February 2020, a single surgeon performed 7 LPS for benign lesions. As primary endpoint, we retrospectively analyzed the patient's short-term outcome and the operative results. As secondary endpoints, we considered 6-month follow-up. Laparoscopic partial splenectomy was performed successfully in all cases, with no major complications. Thirty-day mortality was nil. No post-operative transfusions were required and the median hospital stay was 4 (range 3-5) days. The median operative time was 110 (range 75-140) min and there was neither conversion to open surgery nor need for total splenectomy. Mean blood loss was 135.7 ± 103.6 ml and no intraoperative blood transfusions were necessary. All patients recovered successfully, with significant decrease of Ca 19.9 (98.22 ± 118.10 U/mL vs. 4.78 ± 3.35 U/mL, P = 0.015) and normal platelet count (215.7 × 103 ± 42.2 × 103 per µL vs. 236.0 × 103 ± 58.3 × 103 per µL, P = 0.285) at 1-month follow-up. No cases of recurrence were detected during the 6-month follow-up. Laparoscopic splenic resection for benign lesions is a challenging but feasible procedure. This technique combines the advantages of both mini-invasive surgery and spleen preservation.

Partial splenectomy after preoperative embolization in a patient with metastatic melanoma – A case report

Introduction and importance

There is lack of evidence regarding the best treatment option for metastatic melanoma. In patients with a single splenic metastasis, preoperative superselective embolization followed by partial splenectomy (PS) could be a feasible treatment strategy to preserve splenic function and hopefully reduce the risk of postoperative bleeding. To our knowledge, this two-step procedure has yet not been published in patients with splenic metastasis.

Case presentation

We present the case of a 73-year-old man with stage IV melanoma consisting of a single splenic metastasis located at the lower pole. Four days prior to surgery, the patient underwent percutaneous superselective embolization of the segmental arteries going to the lower splenic pole. Subsequent, PS was performed using an upper midline laparotomy were a clearly visible tumor was found at the devascularized lower third of the spleen. The splenic parenchyma was divided using an energy device and hemostasis was secured with diathermia and a hemostatic patch. The patient had an uncomplicated recovery and was discharged home on postoperative day 8. Histology revealed an 8 mm, partly necrotic metastasis from a melanoma. There were no signs of recurrency at his last control four months postoperative.

Clinical discussion

There are no guidelines on how splenic metastasis from melanoma are to be removed, nor any literature on postoperative splenic function or survival after PS.

Conclusion

Superselective embolization followed by PS for metastatic melanoma could be a feasible treatment approach in highly selective patients where there is a strong desire to preserve splenic function.

•

Total splenectomy is associated with an increased risk of infections, thromboembolism and certain malignancies

•

Partial splenectomy (PS) may be considered to preserve splenic function in cases where a splenic lesion is to be removed

•

Preoperative superselective arterial embolization can be used to devascularize the relevant splenic segment prior to PS

•

To our knowledge, superselective splenic embolization followed by PS has not been published in patients with splenic metastasis

Minimally Invasive Partial Spleen Resection Preserving the Lower Pole in Children: A Technical Report on Feasibility and Safety

Background: Laparoscopic partial splenectomy is a surgical option for removing part of the spleen with a pathological mass in a way that ensures preservation of the spleen's physiological functions. We aimed to evaluate the efficacy and feasibility of this procedure, performed while preserving the blood supply from the left gastroepiploic artery, in children. Materials and Methods: Following institutional review board approval, this retrospective study was conducted on patients who, between January 2015 and December 2019, underwent laparoscopic partial splenectomy with preservation of blood supply from the left gastroepiploic vessels. In the article, we described patient indications for surgery, surgical technique, surgery time, complications, and follow-up outcomes. Results: Eleven patients (mean age: 12.3 ± 3.4 years) underwent laparoscopic partial splenectomy. Indications for surgery included nonparasitic cysts (n = 8), pseudocysts (n = 2), and hamartomas (n = 1). The mean benign mass diameter was 60 ± 22 mm. The mean operative time was 193.2 ± 55.1 minutes. The mean size of the retained lower pole was 31.1% ± 3.8%. There was no conversion to open splenectomy or any significant complication. The mean postoperative stay was 9 ± 0.7 days. No thrombosis of the splenic and portal veins was noted in the follow-up period, and no splenic remnant infarction occurred. Conclusions: Laparoscopic partial splenectomy with preservation of blood supply arising from the left gastroepiploic vessels seems to be safe in children. However, a larger study is needed to confirm our results.

Incidentally discovered asymptomatic splenic hamartoma misdiagnosed as an aneurysm: A case report

BACKGROUND

Splenic hamartoma (SH) is a rare, benign vascular proliferation that is often found incidentally. It may be misdiagnosed as a splenic aneurysm or splenic malignancy.

CASE SUMMARY

A 21-year-old male patient was admitted to our hospital with a complaint of an incidentally discovered asymptomatic splenic space-occupying lesion for 2 wk. Abdominal computed tomography (CT) scan showed a circular low-density shadow in the hilum of the spleen. Contrast-enhanced CT revealed an aneurysm located in the hilum of the spleen before operation. Laparoscopic splenectomy was performed and postoperative pathology revealed the presence of SH.

CONCLUSION

Imaging studies are insufficient for the differential diagnosis of SH from other diseases, and laparoscopic splenectomy is a less invasive procedure and useful for the diagnostic purpose as well.

Laparoscopic Partial Splenectomy: A Critical Appraisal of an Emerging Technique. A Review of the First 457 Published Cases

Background: Laparoscopic partial splenectomy (LPS) may allow avoiding total splenectomy (TS) complications and maximizing the advantages of mini-invasive approach. The objective of this review is to assess feasibility and safety of LPS, to compare this approach with alternative options. Materials and Methods: A literature review of articles reporting LPS is performed. Several parameters, including age, indication, surgical technique, devices used for splenic section/hemostasis, adverse outcomes, including morbidity/mortality, conversions to open surgery, conversions to TS, operative time (OT), and hospital stay (HS), are analyzed. Articles comparing LPS' results with those of open partial splenectomy and laparoscopic TS are also analyzed. Results: Fifty-nine articles reporting 457 LPS were included. Patients' characteristics varied widely, concerning age and indications, including hematological disease (hereditary spherocytosis, drepanocytosis), splenic focal masses, and trauma. Several technical options are reported. Mean OT and HS are 128 ± 43.7 minutes and 4.9 ± 3.8 days, respectively. No mortality and 5.7% morbidity are reported. Conversion rates to open surgery and to TS are 3.9% and 3.7%, respectively. Conclusions: In conclusion LPS is feasible and safe, with no mortality, low morbidity, and low conversion rates to laparotomy and to TS. LPS may be accomplished by various techniques and tools. Major complications are sporadically reported, thus potential risks should not be underestimated.

Laparoscopic partial splenectomy with temporary occlusion of the trunk of the splenic artery in fifty-one cases: experience at a single center

BACKGROUND

Laparoscopic partial splenectomy (LPS) for splenic benign space-occupying lesions has been reported by many researchers; however, few studies have described methods to control intraoperative bleeding. Trustworthy experience in LPS with a satisfactory intraoperative hemorrhage control technique is therefore necessary. The current study aims to present our experience in LPS with temporary occlusion of the trunk of the splenic artery for controlling intraoperative bleeding with a large sample of 51 cases and to evaluate the safety, feasibility, and reproducibility of this technique.

METHODS

Fifty-one patients from August 2014 to April 2019 who underwent LPS in our institution were retrospectively analyzed. Surgical techniques were described in detail.

RESULTS

All patients had successfully undergone LPS with temporary occlusion of the trunk of the splenic artery. Conversions to open surgery, hand-assisted laparoscopic splenectomies, or blood transfusions were not needed. The operative time was 94.75 ± 18.91 min, the estimated blood loss was 71.13 ± 53.87 ml, and the volume of resected spleen was 34.75 ± 12.19%. The range of postoperative stays was 4-14 days. One female patient (2%, 1/51) suffered from postoperative complications. No perioperative mortality, incision infections, postoperative pancreatic fistulas (POPFs), splenic infarctions, or portal/splenic vein thromboembolic events occurred.

CONCLUSION

LPS is an effective spleen-preserving surgery. Although there are many other bleeding control methods, temporarily occluding the trunk of the splenic artery was found to be a safe, feasible, and reproducible technique in LPS. The outcomes of this technique and the efficacy of splenic parenchyma preservation are acceptable.

Spontaneous splenic rupture in a patient with chronic myeloid leukemia: A case report

INTRODUCTION

Spontaneous splenic rupture is an atraumatic event that represents a rare and life-threatening acute complication in which the spleen is damaged producing internal hemorrhage in the abdominal cavity. Its association with hematologic malignancies, although a rare occurrence, has been previously described. Among this subset of patients, chronic myeloid leukemia is one of the main causes.

PRESENTATION OF CASE

A 26-year-old male with history of chronic myeloid leukemia presented with acute intense abdominal right lower quadrant pain. Computed tomography showed a wedge in the lower third of the spleen (probably associated with infarction), active bleeding, and hemoperitoneum. Laparotomy and splenectomy were performed.

DISCUSSION

The most common symptom of spontaneous splenic rupture is acute abdominal pain, sometimes radiating to the left shoulder. It can also be associated with nausea, emesis and signs of hypovolemia or shock. Splenomegaly may be absent. Diagnostic methods of choice are computed tomography and ultrasound. Management of splenic rupture is divided in surgical and conservative. The former is reserved for patients with extensive splenic injury that is accompanied by hemodynamic instability or other trauma that warrants surgical treatment. Patients who do not meet these criteria and respond to initial stabilization strategies can be offered clinical and laboratory monitoring. Stable patients with moderate to severe splenic injuries can be offered angioembolization.

CONCLUSION

It is important to include splenic rupture as a differential diagnosis for acute abdominal pain, especially in patients with hematologic malignancy, since early recognition and treatment increases patient survival and improves prognosis.

Feasibility and Safety of Laparoscopic Partial Splenectomy: A Systematic Review

BACKGROUND

Laparoscopic partial splenectomy (LPS) is a challenging procedure. The aim of this review was to evaluate its feasibility, safety, and potential benefits.

METHODS

We conducted a comprehensive review for the years 1995-2018 to retrieve all relevant articles.

RESULTS

A total of 44 studies with 252 patients undergoing LPS were reviewed. Six studies described combined operations. Ranges of operative time and estimated blood loss were 50-225 min and 0-1200 ml, respectively. There are eight patients need blood transfusion in 231 patients with available data. The conversion rate was 3.6% (9/252). Overall, 27 patients (10.7%;27/252) developed postoperative or intraoperative complications. Overall mortality was 0% (0/252). The length of postoperative stay (POS) varied (1-11 days). Among four comparative studies, one showed LPS could reduce POS than laparoscopic total splenectomy (LTS) (LTS 5.4 ± 1.8 days, LPS 4.2 ± 0.8 days, p = 0.027) and complications (pleural effusion (LTS 9/22, LPS 0/15, p = 0.005), splenic vein thrombosis (LTS 10/22, LPS 0/15, p = 0.002)). Another comparative study showed LPS may benefit emergency patients. However, one comparative study showed LPS was associated with more pain, longer time to oral intake, and longer POS in children with hereditary spherocytosis. The fourth comparative study showed robotic subtotal splenectomy was comparable to laparoscopy in terms of POS and complication. The main benefits were lower blood loss, vascular dissection time, and a better evaluation of splenic remnant volume.

CONCLUSIONS

In early series of highly selected patients, LPS appears to be feasible and safe when performed by experienced laparoscopic surgeons.

Partial splenectomy: Who, when and how. A systematic review of the 2130 published cases

BACKGROUND/PURPOSE

In order to avoid consequences of total splenectomy (including severe postsplenectomy sepsis), partial splenectomy (PS) is increasingly reported. Without guidelines and indications concerning a rarely-indicated procedure, a review of literature should be an asset.

METHODS

A systematic review of all PSs from 1960 to December 2017 was performed, with special focus on surgical indications, sites of resection, approaches and techniques of vascular dissection and parenchymal section/hemostasis of the spleen, perioperative morbidity/mortality, including complications compelling to perform total splenectomy.

RESULTS

Among 2130 PSs, indications for resection were hematological disease in 1013 cases and nonhematological conditions in 1078, including various tumors in 142 and trauma in 184. Parenchymal transection was performed using several techniques through the years, most frequently after having induced partial ischemia by splenic hilum vascular dissection/ligation. 371 laparoscopic/robotic PSs were reported. Rescue total splenectomy was required in 75 patients.

CONCLUSIONS

Although good results are probably overestimated by such a retrospective review, PS should be considered as a procedure associated with a low morbidity/mortality. Nevertheless, severe complications are also reported, and the need of total splenectomy should not to be minimized. Laparoscopic/robotic procedures are increasingly performed, with good results and rare conversions.

Partial splenectomy: A case series and systematic review of the literature

Backgrounds/Aims

Partial splenectomy (PS) is a surgical option for splenic mass, in order to reduce postoperative complications and preserve the splenic function. Despite this, data in literature is still scarce. The present study aimed to reveal our recent experience and provide a comprehensive overview of the feasibility and complications related to various surgical approaches.

Methods

Data of patients who underwent PS, between 2014 and 2017 were retrospectively reviewed. Literature was searched for studies reporting all types of PS in adult or adolescent patients.

Results

Five PS were performed in our department: two (40%) by laparoscopy and three (60%) by laparotomy. Two (40%) postoperative complications were detected, and in one of them, total splenectomy (TS) by laparotomy was finally required. There were no deaths or complications at last follow-up. Twenty studies including 213 patients were identified in the literature search. The rate of conversion from laparoscopic to open surgery was 3% (range, 5–50%) and in 3% of cases (range, 7–10%) PS was converted into total TS and the overall morbidity rate was 8% (range, 5–25%). In comparison to laparotomy, the conversion rate of laparoscopic approach to TS was 3.5% (vs. 1.4%) and a morbidity rate of 9.8% (vs. 4.3%).

Conclusions

The present review shows that PS is a viable procedure in selected cases. The mini-invasive approach seemed to be feasible despite the presence of higher rate of complications than the open technique. In future, further studies on this topic are needed by involving more patients. Furthermore, it is proposed that the development of robotic surgery could make this approach the new gold-standard technique for spleen-preserving surgery.

Laparoscopic hemi-splenectomy

Laparoscopic splenectomy is now established as a safe and feasible procedure. However, it remains associated with some short- and long-term postoperative complications, especially infectious complications. To our knowledge, this is the first report (with video) focusing on the safety and feasibility of laparoscopic hemi-splenectomy and its surgical outcomes for the treatment of splenic abscesses causing septic emboli. This technique combines the immunological benefits of partial splenectomy and the postoperative benefits of a minimally invasive approach. Further studies are needed to standardize this technique and to assess its immunological and surgical benefits.

Feasibility and safety of emergency laparoscopic partial splenectomy: A retrospective analysis

The increased awareness of asplenia-related life-threatening complications has led to the development of parenchyma sparing splenic resections in past few years. The aim of this study is to retrospectively analyze the feasibility and safety of laparoscopic partial splenectomy (LPS) in selected emergency patients.From January 2013 to December 2015, there were 46 emergency patients, diagnosed with splenic rupture, admitted in our department. Selection criteria for LPS: (1) Preoperative CT scan revealed single pole rupture without spleen pedicle injury; (2) BP>90/60 mm Hg and heart rates <120 bpm; (3) No sigh of multiple organ injury. Eventually, LPS was performed in 21 patients (Group LPS), while laparoscopic splenectomy (LS) was performed in 20 patients (Group LS).The main cause of splenic rupture was traffic accident, followed by blunt injury and high falling injury. Abdominal CT scan showed the mean longitudinal diameter of spleen of group LPS was 14.2 ± 1.8 cm (range 12-17 cm), while the size of remnant spleen was 5.5 ± 1.2 cm. Between 2 groups, operation time (LPS: 122.6 ± 17.2 min vs LS: 110.5 ± 18.7 minutes, P = .117), and intraoperative blood loss (LPS: 174 ± 22 mL vs LS: 169 ± 29 mL, P = .331) were similar. There were 2 patients suffered subsequent unstable vital sign altering during mobilization when performing LPS. Conversion to LS (2/21, 9.52%) was decided and successfully completed. Although there was no patient suffered postoperative OPSI or thrombocytosis events in both groups after 6-month follow-up, the mean platelets and leukocyte count were significantly lower in group LPS. Splenic regrowth was evaluated in 20 patients of group LPS. And the mean regrowth of splenic volume reached 19% (10%-26%).Due to its minimal invasive effect and functional splenic tissue preservation, LPS may be a safe and feasible approach for emergency patients. And prospective trials with clear inclusion criteria are needed to proof the benefit of LPS.

Laparoscopic Splenectomy in Patients With Spleen Injuries

INTRODUCTION

Spleen injury appears in 10% to 30% of abdominal trauma patients. Mortality among the patients in the last 20 years remains high (6% to 7%) and shows no tendency to decline. Nowadays nonoperative management is widely accepted management of patients with low-grade spleen injury, whereas management of patients with high-grade spleen injury (III and higher) is not so obvious. There are 3 methods exist in treatment of such patients: conservative (with or without angioembolization), spleen-preserving operations, and splenectomy. Today laparoscopic splenectomy is not a widely used operation and only few studies reported about successful use of laparoscopic splenectomy in patients with spleen injury.The aim of the study was to determine indications and contraindications for laparoscopic splenectomy in abdominal trauma patients and to analyze results of the operations.

PATIENTS AND METHODS

The study involved 42 patients with spleen injury grade III who were admitted in our institute in the years of 2010 to 2014. The patients were divided in 2 groups. Laparoscopic splenectomy was performed in 23 patients (group I) and "traditional" splenectomy was carried out in 19 patients (group II). There was no difference in the demographic data and trauma severity between the 2 groups. Noninvasive investigations, such as laboratory investigations, serial abdominal ultrasound examinations, x-ray in multiple views, and computed tomography had been performed before the decision about necessity of an operation was made.

RESULTS

Patients after laparoscopic operations had better recovering conditions compared with patients with the same injury after "traditional" splenectomy. Neither surgery-related complications nor mortalities were registered in both groups. Laparoscopic splenectomy was more time-consuming operation than "traditional" splenectomy. We suggest that as experience of laparoscopic splenectomy is gained the operation time will be reduced.

CONCLUSIONS

Laparoscopic splenectomy is a safe feasible operation in patients with spleen injury. The operation is indicated in patients with spleen laceration >3 cm of parenchymal depth with moderate continuing bleeding or expanding hematoma and contraindicated in patients with hemodynamic instability and high bleeding rate (>500 mL/h on serial ultrasound examinations).

Spleen hydatidosis treated by hemi-splenectomy: A low-morbidity, cost-effective management by a recently improved surgical technique

BACKGROUND

Splenic hydatidosis is a rare condition and is usually managed by total splenectomy, which is associated to various complications, including overwhelming post-splenectomy sepsis and thrombosis. Probably due to supposed technical difficulties, the partial splenectomy is rarely performed being often unknown to physicians, infectious disease specialists and surgeons.

METHODS

Demographic, clinical and surgical data were collected of four consecutive patients undergoing partial (or hemi-) splenectomy using an original, recently improved technique as a treatment for polar splenic hydatid cyst. The procedure implies a selective vascular ligation, a mechanical stapler-assisted section and haemostatic agents (Surgicel(®)) application on the cutting surface. Three patients were treated by laparotomy (including one affected by both liver and spleen localizations) whereas the last one was approached laparoscopically.

RESULTS

Partial splenectomy operative time reached 74 min (range: 60-94 min) and blood loss was 8 ml (range: 5-10 ml). Hospital stay was 5.6 days (range: 5-7 days). At a mean follow-up of 20 months (range: 12-36 months), outcomes were uneventful.

CONCLUSIONS

Partial splenectomy for hydatidosis is effective and safe. Physicians and surgeons should be aware of such an easy-to-catch option when dealing with benign splenic conditions, such as parasitic cysts. Cost-effectiveness, low morbidity and the possible prevention of splenectomy-related infectious complications should plead in favor of this technique in developing countries, where hydatidosis is endemic and post-splenectomy drugs and vaccines may be lacking.

Partial splenectomy using a laparoscopic bipolar radiofrequency device: A case report

We report a 51-year-old female patient with a solitary lymphangioma located in the upper splenic pole which was managed successfully with laparoscopic partial splenectomy. Surgery lasted 170 min and did not require blood transfusions. The patient recovered well post-operatively and was asymptomatic at the 3-mo follow-up. She had a normal platelet count and no recurrence on ultrasonography or computed tomography. Laparoscopic partial splenectomy is a safe, minimally invasive technique for the treatment of solitary splenic lymphangiomas in the splenic pole. We performed the procedure using the Habib^TM 4X device. This laparoscopic bipolar radiofrequency device ensured a “bloodless” splenic parenchymal resection.

Laparoscopic management of giant splenic true cyst with partial splenectomy: a case report

Non-parasitic splenic cysts are relatively rare, and the optimal surgical treatment for them remains controversial. Laparoscopic unroofing is a relatively safe and easy technique, but a significant number of recurrences has been reported. Thus, complete cystectomy with partial splenectomy is recommended by several surgeons. However, patients sometimes suffer from intraoperative bleeding. Here, we report a patient with a giant non-parasitic splenic cyst who underwent subtotal cystectomy with partial splenectomy. After the dissection of the vessels circulating the upper pole at the splenic hilum, the resection line of the splenic parenchyma was on the ischemic side of the cyanotic demarcation line. A vessel sealing system and laparoscopic coagulation shears were used for the resection. We intentionally left about 10% of the cyst wall to avoid bleeding from the non-ischemic splenic parenchyma and remaining vessels. No recurrence has been detected after 6 months of observation. We believe this method could be a useful alternative procedure for the treatment of non-parasitic splenic cysts and preservation of the splenic parenchyma.

3D virtual rendering before laparoscopic partial splenectomy in children

INTRODUCTION

Partial splenectomy in children is a good surgical option for hematological diseases and focal splenic tumors because it allows the preservation of the spleen's immunological function. Furthermore, it can be performed by laparoscopy in children as it is a safe procedure, offering the benefits of a minimally invasive approach.

MATERIALS AND METHODS

The software VR-render LE version 0.81 is a system that enables the visualization of bidimentional 3D images with magnification of anatomical details. We have applied this system to five cases of non-parasitic splenic cysts before laparoscopic partial splenectomy.

RESULTS

The images obtained with VR rendering software permitted the preoperative reconstruction of the vascularization of the splenic hilum, allowing the surgeon safe vessel control during laparoscopic procedures. All five partial splenectomies were carried out with no complications or major blood loss.

CONCLUSIONS

Laparoscopic partial splenectomy should be a first choice procedure because it is feasible, reproducible, and safe for children; furthermore, it preserves enough splenic tissue thereby preventing post-splenectomy infections. Volume rendering provides high anatomical resolution and can be useful in guiding the surgical procedure.

Hydatid cyst of spleen: a diagnostic challenge

Although splenic involvement alone in hydatid disease is very rare, spleen is the third most common organ involved in hydatid disease. The rarity of splenic hydatid disease poses a diagnostic challenge for clinicians, particularly in non-endemic areas. As the hydatid cyst can present as a simple cyst without having the classic serological and imaging features, and later can lead to life-threatening complications like anaphylaxis, hydatid disease of spleen should be considered in differential in every patient in endemic areas with cystic lesion of spleen until proved otherwise. The author used the keyword “splenic hydatid cyst” in PubMed and reviewed the scientific literatures published from January 1965 to June 2012. The present review is to accentuate the incidence, classification, clinical and pathophysiological features, differential diagnosis, diagnostic modalities, and treatment choices of hydatid cyst of spleen along with follow-up strategy and newer treatment approaches.

Laparoscopic splenectomy for splenic hamartoma: a case report

Hamartoma is a rare splenic benign tumor usually accidentally detected as a radiologic finding. Preoperative diagnosis poses a challenge and thus surgery becomes necessary to confirm the clinical suspicion. Laparoscopic splenectomy has gained consensus as a standard surgical procedure particularly for autoimmune hematological diseases. This former experience has allowed this technique to be extended to other splenic pathologies. Here we report a case of total laparoscopic splenectomy for a bulky splenic hamartoma in a young male patient.

Incidental finding of a splenic hamartoma with tumour-like extramedullary erythropoiesis

Hamartomas of the spleen are rare benign tumour-like lesions that tend to be asymptomatic incidental findings. Splenic hamartomas with tumour-like extramedullary erythropoiesis are extremely rare. A 70-year-old male patient with dyspnoea and a nodular intrapulmonary lesion morphologically verified by CT underwent fibre bronchoscopy, which showed a pea-shaped foreign body that was retrieved without complication. As a secondary finding, the CT showed a splenic lesion of about 8 cm in size. An MR study showed an expansive process in the center of the spleen. The patient was completely free of clinical symptoms. Because of the unknown nature and the high risk for spontaneous rupture of the lesion, a splenectomy was performed. The histological analyses revealed tumour-like extramedullary erythropoiesis of the spleen. The patient was discharged in good condition ten days postoperatively. A hamartoma of the spleen with extramedullary tumor-like erythropoiesis should be considered in the differential diagnosis of a splenic lesion.

Robot-assisted partial and total splenectomy

BACKGROUND

The interest of robotics in performing partial and total splenectomy is poorly reported so far. We report herein our experience.

METHODS

From November 2001 to November 2009, 24 consecutive robotic splenectomies were performed by the same surgeon. All data were prospectively collected and reviewed retrospectively.

RESULTS

Twelve men and 12 women with a median age of 48 years underwent a robotic splenectomy, three of which were partial splenectomies. The indications were: ABO incompatibility for kidney transplantation (n = 7), haematological disease (n = 7) and miscellaneous pathologies (n = 10). Mean operative time was 199 ± 65 min. Median blood loss was 75 (range 5-300) ml. There was one intraoperative complication and two conversions. The postoperative morbidity was 8.3% with no mortality. Median hospital stay was 5.5 days.

CONCLUSIONS

This series reports the safety and feasibility of robotic partial and total splenectomy. Its use as an alternative to the standard laparoscopic approach is particularly beneficial in more challenging cases.

Laparoscopic partial splenectomy for littoral cell angioma

Littoral cell angioma (LCA) is a rare benign splenic vascular neoplasm. We report a case of a 58-year-old man with a 5.5-cm lesion in the upper pole of the spleen. A laparoscopic partial splenectomy was performed. He was discharged on the second postoperative day. Pathology revealed LCA.

Laparoscopic partial splenectomy can be performed safely in selected cases and is an appropriate option in patients with benign conditions as it enables preservation of the immunologic function of the spleen. Long-term follow up in patients with LCA is important given its high association with other malignancies.

Robotic partial splenectomy for hydatid cyst of the spleen

BACKGROUND

Primary splenic involvement is an uncommon manifestation of hydatid disease. Partial laparoscopic splenectomy can be performed with lower risks and good hematological results by preserving the immunological function of the spleen. The aim of this study was to outline the advantages of robotic partial splenectomy as a treatment for splenic hydatid cysts.

MATERIALS AND METHODS

Four patients with splenic hydatidosis were treated by robotic approach. The patients included one man and three women, with a mean age of 24 years (range 16–34). The localization was in the upper pole in one case and voluminous cysts in the hilar region in the other three.

RESULTS

Robotic hemisplenectomy was performed in the upper pole localized cyst and robotic subtotal splenectomy with lower pole preservation in the other three. The mean operative time was 120 min (±37 min) with a console time of 95 min (±28 min); the mean hospital stay was 5 days (±2 days).

CONCLUSION

Partial robotic splenectomy seems to offer safety and all benefits of minimally invasive surgery, preserves the immune function of the spleen and allows the surgeon to conserve as much of the splenic parenchyma as possible.

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.

Open partial splenectomy for trauma using GIA-Stapler and FloSeal matrix haemostatic agent

A ruptured spleen caused by blunt abdominal injury is often treated by splenectomy. In view of the gravity of the 'postsplenectomy syndrome,' a conservative approach has been increasingly used. We present the case of a 29-year-old man with a Grade III splenic lesion for a blunt abdominal trauma after a car accident. We performed a partial splenectomy of the upper pole using GIA-Stapler. A supplemental haemostasis of the stapled line was successfully achieved by the application of FloSeal matrix haemostatic agent. The splenic remnant was fixed into the left-upper quadrant using human fibrin glue.

Laparoscopic partial splenectomy using a detachable clamp with and without partial splenic embolisation

BACKGROUND

In many centres, the laparoscopic total splenectomy is a well-established routine procedure. However, the crucial immunological role of the spleen in combating bacterial infections, in particular pneumonias, has led to a search for splenic-preserving techniques whenever possible. Yet, laparoscopic partial splenectomies are still rarely described possibly due to difficulties in controlling intra-operative parenchymal bleeding during splenic transection.

METHODS

Here, we present a case series of laparoscopic partial splenectomies using a new technique. The main splenic artery and vein were temporarily clamped using a detachable clip. Transection of the spleen was possible working with the LigaSure™ instrument. After transection, the margin was sealed with a collagen fleece. In one case of a haemangioma, the patient underwent a radiological coil embolisation of the feeding arteries of the splenic pole in question. This was done 4 weeks prior to surgery and included embolisation of the tumour.

RESULTS

Three patients (2 males, 1 female, mean age 58.3 years) have been successfully treated using a detachable clamp. The pre-surgical mean size of the spleen was 8.0 × 16.7 cm (range 6 × 14-11 × 22 cm). The removed specimens had a mean size of 4.2 × 5.5 cm (range 2.5 × 4.0-5.0 × 6.5 cm). The time of surgery averaged 144 min (range 110-187 min). Blood loss was minimal thereby avoiding the need for blood transfusions. The post-surgical course was uneventful; patients were discharged 5 days following surgery. Histopathology showed a benign splenic haemangioma, a benign splenic hamartoma and the presence of Hodgkin's disease stage III.

CONCLUSIONS

The technique of laparoscopic partial splenectomy and, in certain patients, pre-surgical partial splenic embolisation is safe and effective for patients with localised diseases of the spleen. This approach combines the benefits of the minimal surgical access with saving a significant amount of splenic tissue, thereby preserving the immune function of the spleen.

Laparoscopic splenectomy for splenic hamartoma: Case management and clinical consequences

Splenic hamartoma is a rare benign tumor, and although minimally invasive surgery may be suitable for this condition, there have only been 2 previous reports of laparoscopic surgery. Here we report the third case of splenic hamartoma managed by laparoscopic splenectomy. A 37-year-old male was incidentally diagnosed by abdominal ultrasonography with a hypoechoic mass measuring 2.5 cm × 2.4 cm in the spleen. Color Doppler sonography showed multiple flow signals within the mass and contrast-enhanced computed tomography revealed strong enhancement of the lesion. On T1- and T2-weighted magnetic resonance images, the splenic mass was demonstrated as isointense and hyperintense respectively. Although a malignant tumor could not be ruled out, a hand-assisted laparoscopic splenectomy was performed because the splenic mass was limited in size and had not invaded adjacent organs. The pathological diagnosis was splenic hamartoma. The postoperative course was uneventful and the patient was discharged by the seventh postoperative day. Although splenic hamartomas have some specific imaging features, more reports and analyses of these cases are required to increase the reliability of the diagnosis and management. Hand-assisted laparoscopic splenectomy may play a pivotal role in the postoperative diagnosis and management of this condition.

[Laparoscopic splenectomy: indications, techniques, outcomes]

Laparoscopic splenectomy (LS) has become the standard approach to splenectomy for benign and malignant hematologic diseases despite a paucity of high-level evidence. The procedure requires expertise in laparoscopic surgical techniques and meticulous dissection of the spleen. Management should include a preoperative radiologic assessment to measure splenic volume and to detect the presence of accessory splenic tissue; the patient should undergo preoperative vaccination against meningococcal, pneumococcal, and Haemophilus influenzae type B infections. Prophylactic antibiotics are used in the perioperative period as well as prophylactic anticoagulation therapy which may be continued long-term in high-risk patients. LS is associated with a low morbidity and mortality; when compared to laparotomy, it reduces the length of hospital stay and improves the quality of life by decreasing postoperative ileus and pain. There are a variety of laparoscopic approaches; the hand-assisted technique and newer coagulating devices have facilitated the operative technique leading to increasing acceptance of laparoscopy as the preferred approach - even in patients with malignant hematologic disease and/or massive splenomegaly.

Partial splenectomy in the management of nonparasitic splenic cysts

BACKGROUND

Recognition of the importance of the spleen in immunological function and the potential threat of severe postsplenectomy complications have led to the development of parenchyma-preserving surgical procedures. The aim of the present study was to assess the impact of open splenic partial resection on the management of splenic cysts.

PATIENTS AND METHODS

From April 2003 to June 2007, 11 patients with splenic cysts were evaluated. All patients fulfilled the criteria for surgical resection. Ten of the patients (6 women and 4 men) 15-42 years of age (mean: 26.4 years) were subjected to open partial splenectomy. In one patient, a centrally located splenic cyst was considered unsuitable for partial splenectomy, and the patient therefore underwent total spleen excision. Patients with splenic cysts constituted 3.8% of all 290 patients subjected to splenectomy during the study period. Spleen parenchyma was cut with the aid of a LigaSure instrument. Bleeding from the transected splenic parenchyma was secured with argon plasma coagulation and absorbable tape sutures or oxidized cellulose.

RESULTS

Nine of the ten patients underwent successful partial splenectomy. In one patient, insufficient arterial supply to the preserved splenic remnant after excision of the upper cyst-containing splenic pole led to total splenectomy. The mean operative time was 98 min (range: 85-160 min), and mean blood loss was 106 ml (55-200 ml). The mean cyst diameter was 9.1 cm (range: 7-17 cm) and weight was 738 g (range: 230-2,420 g). The postoperative course was uneventful in all cases. Pathological examination showed an epithelial cyst in 8 patients and a pseudocyst in 2. After a mean follow-up of 26.4 months, the size of the splenic remnant constituted, on average, 71% of preoperative spleen size. Moreover, normal splenic vein flow was observed. Platelet counts remained within the normal range, and no cyst recurrence was observed. There were no infections documented during the follow-up period.

CONCLUSIONS

Open partial splenectomy is a safe and effective method in the management of nonparasitic splenic cysts. It ensures complete cyst removal, lack of cyst recurrence, and preservation of the spleen functions.

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.

Laparoscopic partial vs total splenectomy in children with hereditary spherocytosis

BACKGROUND

Open partial splenectomy provides reversal of anemia and relief of symptomatic splenomegaly while theoretically retaining splenic immune function for hereditary spherocytosis. We recently developed a laparoscopic approach for partial splenectomy. The purpose of the present study is to compare the outcomes in a group of patients undergoing laparoscopic partial splenectomy (LPS) with those in a group of children undergoing laparoscopic total splenectomy (LTS) over the same period.

METHODS

Systematic chart review was conducted of all children with hereditary spherocytosis who had LTS or LPS from 2000 to 2006 at the Hospital for Sick Children, Toronto, Ontario, Canada. T tests were used for continuous data, and chi(2) for proportional data; P value of less than .05 was considered significant.

RESULTS

There were 9 patients (14 males) in each group. Groups were similar in sex, age, concomitant cholecystectomy, and preoperative hospitalizations, transfusions, and spleen size. Estimated blood loss was greater in the LPS group (188 + 53 vs 67 + 17 mL; P = .02), but transfusion requirements were similar (1/9 vs 0/9). Complication rate was similar between groups. The LPS group had higher morphine use (4.1 + 0.6 vs 2.4 + 0.2 days; P = .03), greater time to oral intake (4.4 + 0.7 vs 2.0 + 0.2 days; P = .01), and longer hospital stay (6.3 + 1.0 vs 2.7 + 0.3 days; P = .005) than the LTS group. Nuclear scan 6 to 8 weeks postoperatively demonstrated residual perfused splenic tissue in all LPS patients. No completion splenectomy was necessary after a mean follow-up of 25 months.

CONCLUSION

These data suggest that LPS is as effective as LTS for control of symptoms. However, LPS is associated with more pain, longer time to oral intake, and longer hospital stay. These disadvantages may be balanced by retained splenic immune function, but further studies are required to assess long-term splenic function in these patients.

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 splenectomy: the clinical practice guidelines of the European Association for Endoscopic Surgery (EAES)

BACKGROUND

Although laparoscopic splenectomy (LS) has become the standard approach for most splenectomy cases, some areas still remain controversial. To date, the indications that preclude laparoscopic splenectomy are not clearly defined. In view of this, the European Association for Endoscopic Surgery (EAES) has developed clinical practice guidelines for LS.

METHODS

An international expert panel was invited to appraise the current literature and to develop evidence-based recommendations. A consensus development conference using a nominal group process convened in May 2007. Its recommendations were presented at the annual EAES congress in Athens, Greece, on 5 July 2007 for discussion and further input. After a further Delphi process between the experts, the final recommendations were agreed upon.

RESULTS

Laparoscopic splenectomy is indicated for most benign and malignant hematologic diseases independently of the patient's age and body weight. Preoperative investigation is recommended for obtaining information on spleen size and volume as well as the presence of accessory splenic tissue. Preoperative vaccination against meningococcal, pneumococcal, and Haemophilus influenzae type B infections is recommended in elective cases. Perioperative anticoagulant prophylaxis with subcutaneous heparin should be administered to all patients and prolonged anticoagulant prophylaxis to high-risk patients. The choice of approach (supine [anterior], semilateral or lateral) is left to the surgeon's preference and concomitant conditions. In cases of massive splenomegaly, the hand-assisted technique should be considered to avoid conversion to open surgery and to reduce complication rates. The expert panel still considered portal hypertension and major medical comorbidities as contraindications to LS.

CONCLUSION

Despite a lack of level 1 evidence, LS is a safe and advantageous procedure in experienced hands that has displaced open surgery for almost all indications. To support the clinical evidence, further randomized controlled trials on different issues are mandatory.
