Guidelines for the performance of minimally invasive splenectomy

Abstract

Background: Minimally invasive splenectomy (MIS) is increasingly favored for the treatment of benign and malignant diseases of the spleen over open access approaches. While many studies cite the superiority of MIS in terms of decreased morbidity and length of stay over a traditional open approach, the comparative effectiveness of specific technical and peri-operative approaches to MIS is unclear.

Objective: To develop evidence-based guidelines that support clinicians, patients, and others in decisions on the peri-operative performance of MIS.

Methods: A guidelines committee panel of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) including methodologists used the Grading of Recommendations Assessment, Development and Evaluation approach to grade the certainty of evidence and formulate recommendations.

Results: Informed by a systematic review of the evidence, the panel agreed on eight recommendations for the peri-operative performance of MIS for adults and children in elective situations addressing six key questions.

Conclusions: Conditional recommendations were made in favor of lateral positioning for non-hematologic disease, intra-operative platelet administration for patients with idiopathic thrombocytopenic purpura instead of preoperative administration, and the use of mechanical devices to control the splenic hilum. Further, a conditional recommendation was made against routine intra-operative drain placement.
