Laparoscopic Splenectomy Is a Safe Method in Cases of Extremely Large Spleens

Laparoscopic Splenectomy Versus Open Splenectomy In Massive and Giant Spleens: Should we Update the 2008 EAES Guidelines?

The objective of this study was to derive some useful parameters to define the feasibility of laparoscopic splenectomy (LS) in massive [spleen longitudinal diameter (SLD)>20 cm] and giant spleens (SLD>25 cm). Between December 1996 and May 2017, 175 patients underwent an elective splenectomy. A laparoscopic approach was used in 133 (76%) patients. Massive spleens were treated in 65 (37.1%) patients, of which 24 were treated laparoscopically. In this subset of massive spleens, the results of laparoscopic splenectomy in massive spleens (LSM) and open splenectomy in massive spleens (OSM) were compared. The clinical outcome of a subgroup of patients with giant spleens was also analyzed. The LSM group resulted in significant longer operative times (143±31 vs. 112±40 min; P=0.001), less blood loss (278±302 vs. 575±583 mL; P=0.007), and shorter hospital stay (6±3 vs. 9±4 d; P=0.004). No conversions were experienced in the LSM group, and the morbidity rate was similar in both the LSM and OSM groups (16.6% vs. 20%; P=0.75). When considering the subset of 9 LSM patients and 26 OSM patients with giant spleens, the same favorable tendency of the laparoscopic group as regards surgical conversion, blood loss, and hospital stay was maintained. The laparoscopic approach can be successfully proposed in the presence of massive splenomegaly also after a careful preoperative evaluation of the expected abdominal "working space." In experienced hands, LS is safe, feasible, and associated with better outcomes than open splenectomy for the treatment of massive and giant spleen, with a maximum SLD limit of 31 cm.

Predictive Factors for Success of Laparoscopic Splenectomy for ITP

Background and Objectives:

Therapy-resistant immune thrombocytopenia (ITP) is the most frequent indication of laparoscopic splenectomy (LS). It ensures the best results for this disease compared with possible second-line pharmacologic therapies. Therefore, learning about the safety of the surgical method and its long-term efficacy is important, as is selecting patients who respond to surgical treatment. Our purpose was to analyze the safety of LS and the short-and long-term prognostic significance of known perioperative parameters.

Methods:

We performed 40 LSs for ITP from January 1, 2000, to January 1, 2015. We analyzed the roles of the perioperative parameters by using evidence-based guidelines.

Results:

Complete response (CR; platelet count over 100 × 10⁹/L) occurred in 28 cases (70%) and partial response (PR; platelet count between 30 and 100 × 10⁹/L) in 5 cases (12.5%). Below the age of 50, 9% (2/22) of the patients had no response (NR; platelet count not increasing over 30 × 10⁹/L), 28% (5/18) over the age of 50 (P = .023) had no response. In the steroid-refractory group, 30% did not respond, whereas 100% of the steroid-dependent patients had a CR (NR: 7/23 steroid refractory vs 0/17 steroid dependent; P = .027). The patients were followed up for a mean of 10.9 ± 6.9 years, and a long-term response (LTR) was detected in 21 of the responders (n = 33). Of the patients who originally had a CR, 71% also achieved LTR, whereas only 20% of the PR patients did.

Conclusion:

LS is safe and remains the most effective second-line treatment for ITP. In our study, younger age and response to preoperative steroids were predictive factors for the long-term success of splenectomy.

Validation of a Difficulty Grading Score in Laparoscopic Splenectomy

INTRODUCTION

Laparoscopic splenectomy (LS) is the gold standard for the treatment of many spleen-related disorders. However, in the presence of splenomegaly, the rate of conversion to open surgery can be as high as 33.9% and is associated with longer operative times and higher costs. In an attempt to improve risk stratification and patient selection for LS, a score that includes four preoperative parameters (age, gender, diagnosis, and spleen size) has been developed. The aim was the validation of a difficulty grading score, in predicting conversion and poorer outcomes.

METHODS

Retrospective analysis of 153 consecutive patients subjected to LS from January 2006 through December 2016 was performed. Several parameters were reviewed and correlation with evaluated outcomes was analyzed.

RESULTS

Conversion to open surgery occurred in 13 (8.50%) patients and was highly associated with serious intraoperative complications. Spearman correlation showed a significant association between the score and risk of conversion, operative time, and postoperative complications, but not with intraoperative bleeding.

DISCUSSION

Patient and disease features, incorporated in a difficulty grading score, can reliably determine the difficulty of LS and predict risk of conversion, intraoperative, and postoperative complications. This simple and reproducible score improves risk stratification for LS and could be practical in daily clinical activities.
