Background/aims: To compare the outcomes and potential morbidities of laparoscopic spleen-preserving distal pancreatectomy with or without splenic vessel preservation in patients with benign or low-grade malignant pancreatic lesions.
Methodology: Twenty patients who underwent spleen-preserving distal pancreatectomy were retrospectively analyzed. All the patients had benign or low-grade malignant pancreatic lesions that had not invaded the spleen. Twelve patients underwent Kimura's procedure and eight patients underwent Warshaw's. Perioperative data, and procedure-specific complications were compared between the two groups.
Results: Age, gender, and body mass index were comparable between the two groups. Operative time and intraoperative blood loss were significantly lower for patients who underwent Warshaw's procedure than for those who received Kimura's (p <0.05 for both). There were no significant differences between the two groups with regard to perioperative blood transfusions, length of postoperative hospital stays, or complication rates. Splenic infarction and gastric varices developed only in patients who underwent Warshaw's procedure (one case each).
Conclusions: Our results suggest that the Kimura technique should be the first choice for patients with benign or low-grade malignant pancreatic lesions. Warshaw's technique was associated with a higher incidence of several complications. However, Warshaw's can increase the success rate of splenic preservation in some cases.
