Laparoscopic Partial Splenectomy: A Preferred Method for Select Patients

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.

Laparoscopic management of benign splenic tumors in children

Background

The splenic tumor is relatively rare in children. However, diagnosing and managing this disease remain controversial. This study aimed to evaluate the clinical characteristics and pathological features of benign splenic tumors and to explore the feasibility and safety of laparoscopic splenectomy in children.

Methods

The clinical data of all patients who were diagnosed with benign splenic tumors and admitted to our center between January 2014 and December 2020 were analyzed retrospectively. Factors that were documented included demographic criteria, clinical manifestations, preoperative examinations, surgical methods, histopathological characteristics, postoperative complications and outcomes.

Results

Totally, 24 consecutive patients with a mean age of 10.21±2.59 years were operated laparoscopically. Nine patients presented with recurrent abdominal pain, vomiting or backache. The remaining 15 cases were asymptomatic and were identified incidentally. Laparoscopic total splenectomy (LTS) was performed in 12 cases, laparoscopic partial splenectomy (LPS) in 9 cases and deroofing of splenic cyst in 3 cases. No significant differences were observed in operation time, intraoperative bleeding and postoperative abdominal drainage between the LTS and LPS groups. Histopathology examination reported 12 cases of splenic epithelial cyst, 5 cases of splenic lymphangioma or lymphatic malformation, 3 cases of splenic hamartoma, 3 cases of splenic littoral cell angioma and 1 case of splenic hemangioma. No postoperative complications and tumor recurrence were observed.

Conclusions

It is still difficult to precisely diagnose the splenic tumor preoperatively. Laparoscopic splenectomy is safe and feasible in treating the benign splenic tumors, and partial splenectomy is of great significance in preserving the immune function in children.

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.

Clinical effect of laparoscopic partial splenectomy for both benign tumours and trauma-10 years of experience at a single institution

BACKGROUND

This retrospective study aimed to present our surgical experience in patients with benign tumour or trauma in spleen who underwent laparoscopic partial splenectomy (LPS) and to compare the results with those of patients who underwent an open partial splenectomy (OPS).

METHODS

We analysed the medical data of patients who underwent LPS or OPS between January 2010 and January 2020.

RESULTS

In total, 41 patients were enrolled. Nine patients underwent open surgery, 32 patients underwent laparoscopic surgery. The proportion of patients with tumours in the upper pole in LPS group was more than patients in OPS group. No difference was observed in estimated blood loss, allogeneic transfusion, postoperative stay, pathology and complications between LPS and OPS groups. The operation time in the LPS group (137.5 ± 30.8 min) was longer than that in the OPS group (88.3 ± 30.1 min) for patients with splenic traumatic rupture (P = 0.019).

CONCLUSIONS

LPS is an effective and safe spleen-preserving surgery as OPS. The advantages are small trauma, light pain and quick recovery. It is suitable for patients with benign tumours or trauma confined to one side of the spleen.

Functional Evaluation of a Novel Microwave Surgical Device in a Canine Splenectomy Model

Aim: Partial splenectomy remains a difficult procedure even with the assistance of a sealing system. Recently, a scissor-like microwave energy device (Acrosurg) that provides seamless coagulation and manual cutting has been applied in surgery. The objective of this study is to evaluate the surgical capabilities of Acrosurg in partial splenectomy. Materials and Methods: Acrosurg and Harmonic Focus (HF) were employed for partial splenectomy in dogs without prior ligation of vessels. Cutting time, cutting area, and bleeding were recorded. Lateral thermal injury (LTI), possible complications was observed immediately and after 4 weeks. Results: The manual cutting mechanism of Acrosurg required a longer cutting time compared with the automatic cutting mode of HF (301.5 [243.2-527] vs. 114.5 [106.0-135.0] sec, p < 0.01). There was no statistical difference in cutting area or bleeding cases. Acrosurg achieved complete hemostasis in all cases, whereas the HF group failed to stop bleeding in two of the eight cases. The Acrosurg group exhibited a similar LTI compared with the HF group (3.0 [2.4-3.4] vs. 2.7 [2.3-2.9] mm, p = 0.151), but the LTI of the Acrosurg group tended to shrink more after 4 weeks (1.2 [1.0-1.3] vs. 1.7 [1.3-1.9] mm, p < 0.05). Conclusions: A microwave energy device enabled a partial splenectomy without vessel ligation. The combination of manual cutting and sealing capability helps not only provide an appropriate seal time by adjusting cutting timing adaptively but also potentially stop bleeding by using a microwave heating process unlike other energy devices.

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 middle segment splenectomy for central splenic hemangioma: A case report

•

Laparoscopic middle segment splenectomy for central splenic hemangioma is a new technique.

•

Laparoscopic middle segment splenectomy for central splenic hemangioma is very useful for some selected patients.

•

In patients with splenic artery bifurcation point far from the splenic hilus parenchyma and in those cases where the blood supply of the upper and lower pole splenic segments can be ensured, when the splenic tumor is resected, performing LPS and retaining some upper and lower splenic segments is possible to ensure sufficient residual spleen.

Introduction

Laparoscopic surgery plays an important role in the treatment of splenichematologic pathologies and solid lesions. Splenic hemangioma is the most common benign tumor of the spleen. In patients with benign splenic space-occupying lesions, laparoscopic partial splenectomy (LPS) has a lower incidence of postoperative complications than laparoscopic total splenectomy (LTS). Currently, no uniform standard for the indication of LPS is available.

Presentation of case

Herein, we report a case of hemangioma in a 23-year-old woman treated with LPS. After multidisciplinary evaluation, laparoscopic splenectomy was indicated in this case; upon evaluating the age of the patient and the affected spleen portion, a middle segment splenectomy was proposed, with preservation of the upper and lower pole. The intraoperative frozen section of the specimen was negative for malignancies.

Discussion

Surgery remains the first choice in the treatment of solid lesions of the spleen. In this case, the volume of splenic hemangioma was large and accumulated in the upper and lower segments of the spleen. After the middle branch of splenic artery was cut off, the tumor was completely contained in the middle of upper and lower ischemic lines splenic segment. We think that the central type of benign splenic space occupying is not an absolute contraindication of LPS. For the patients whose splenic artery bifurcation point is far from the splenic hilus parenchyma and in those cases where the blood supply of the upper and lower poles of the splenic segments can be ensured, when the splenic tumor is resected, performing LPS and retaining some parts of the upper and lower splenic segments is possible to ensure sufficient residual spleen.

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: 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.
