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.

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.

Methods and techniques of laparoscopic partial splenectomy

The spleen is the most important immune organ of the human body, playing an important role in maintaining the immune balance of the body. More and more studies have shown that the body's specific and non-specific immune function decreases after splenectomy, and as a result, infection and tumor susceptibility increases. Laparoscopic partial splenectomy, a new surgical method of spleen preservation, has gotten increasing clinical application. Laparoscopic partial splenectomy is minimally invasive and is associated with quick recovery; however, this operation is difficult to perform and often causes bleeding. In recent years, our department has used bipolar radiofrequency Habib 4X in laparoscopic partial splenectomy to achieve good results. This article focuses on the methods and techniques of laparoscopic partial splenectomy.

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.

Renal sparing surgery using focus ultracision harmonic scalpel in patients with bilateral wilms' tumor: case report

BACKGROUND

Bilateral Wilms' tumor is rare and surgical treatment requires an individual approach. Surgical approach to the tumors located in the central part of the kidney represents a major challenge and nephrectomy is usually essential. Renal sparing surgery is difficult in such cases.

CASE REPORT

We describe a 3 year-old female patient with bilateral Wilms' tumor arising in the central localisation of the right and foci in the left kidney enucleated successfully with a simple and comfortable renal preserving operative technique using Focus Ultracision Harmonic Scalpel.

CONCLUSION

In cases when tumors are located in the central part of the kidney and partial nephrectomy is consequently very difficult, the use of a Focus Ultracision Harmonic Scalpel provides easy dissecting, enucleation, and excision of the tumor.
