ARTICLE HIGHLIGHTS
Research background

Many studies have explored potential predictors of morbidity after distal pancreatectomy. All the reported studies included both patients with and without spleen preservation. Some studies have suggested that there might be some differences in outcomes between the patients with distal pancreatectomy, with and without spleen preservation. To date, there is no study to explore potential predictors of postoperative morbidity in a group of patients with only spleen-preserving distal pancreatectomy. The aim of the study is to identify risk factors for clinically relevant morbidity after spleen-preserving distal pancreatectomy in a single surgical center experience.

Research motivation

Morbidity after spleen-preserving distal pancreatectomy remains a significant concern and preservation of the spleen during distal pancreatectomy might sometimes be technically challenging. Thus, identification of potential predictors of clinically relevant morbidity in patients with spleen-preserving distal pancreatectomy would be of interest for clinical practice to better select the patients for this type of surgical procedure.

Research objectives

The primary objective of the study was to explore potential predictors of clinically relevant morbidity after spleen-preserving distal pancreatectomy in a single surgical center experience.

Research methods

It was a retrospective analysis reviewing the data of 41 consecutive patients who underwent spleen-preserving distal pancreatectomy with spleen vessel preservation between 2000 and 2015 in our Department of Surgery. Appropriate statistical tests were used to compare potential risk factors between the groups of patients with and without clinically relevant morbidity after spleen-preserving distal pancreatectomy, in uni- and multivariate analyses.

Research results

To the best of our knowledge, this is the first study exploring potential predictors of clinically relevant morbidity in patients with spleen-preserving distal pancreatectomy. The study found male gender and increased body mass index as independent predictors of clinically relevant morbidity after spleen-preserving distal pancreatectomy.

Research conclusions

This is the first study that identifies male gender and increased body mass index as risk factors of clinically relevant morbidity in a group of patients with only spleen-preserving distal pancreatectomy. Patient-related factors such as gender and body mass index should be taken into consideration when a spleen-preserving distal pancreatectomy is proposed. The data provided in the present study can be used for clinical decision-making, particularly when preservation of the spleen during distal pancreatectomy is technically demanding.

Research perspectives

Preoperative evaluation of patients suitable for a spleen-preserving distal pancreatectomy is of utmost importance. The impact of male gender and body mass index on postoperative outcome after spleen-preserving distal pancreatectomy remains to be explored in future studies including more substantial number of patients.
