The role of laparoscopic splenectomy in traumatic splenic injury: a narrative review.

INTRODUCTION

Splenic injuries are one of the commonest occurrences in abdominal trauma. Nonoperative management (NOM) is the treatment of choice in hemodynamically stable patients with low grade injuries in the absence of vascular injury on CT; however, in some cases, NOM can fail and surgery is required. Traditionally, splenectomy is performed via laparotomy but, recently, the use of laparoscopy is rapidly increasing because the numerous advantages it offers for selected trauma patients.

EVIDENCE ACQUISITION

A systematic review of the literature was performed through Medline for papers on the laparoscopic splenectomy (LS) in trauma patients, published from January 2006 to July 2022. The inclusion criteria were the study population consisted of hemodynamically stable adult patients treated with LS, as primary treatment or in case of complication or failure of NOM. The data extracted included gender, patient age, type of trauma, ISS, indication for LS and if LS was performed primary or secondary to NOM. The considered outcomes were operative time, length of stay, morbidity and mortality.

EVIDENCE SYNTHESIS

Eight papers were considered suitable for the study and all the articles were retrospective studies and only one of them was multicentered. A total of 202 patients were included in the study and all of these suffered splenic trauma and all patients were hemodynamically stable or responding to fluid resuscitation. Trauma mechanism was blunt in 92.9% of cases and penetrating in 7%. Twenty-one patients underwent LS after failure of angioembolization. Operative time of LS was reported in 6 papers and the mean was 130.7 mins. Length of stay was reported in 7 papers and the mean was 8.12 days. Overall morbidity was 7.7% and the postoperative mortality was cited in 6 articles with an overall percentage of 2.5%.

CONCLUSIONS

Laparoscopy should be considered a valid alternative to open surgery, in hemodynamically stable patients and when performed by an experienced surgeon, such as the minimally invasive trauma surgeon.
