Background: Although recent studies have reported potential benefits of laparoscopic approach in distal pancreatectomy, reports of conversion during minimally invasive distal pancreatectomy (MIDP) were limited. Methods: This was a retrospective study using data from Sir Run Run Shaw Hospital around May 2013 to December 2018. Outcomes of patients who had conversions during MIDP were compared with patients with successful MIDP and with patients undergoing open distal pancreatectomy (ODP). Results: Two-hundred and eighty-three cases were included in this study: 225 (79.5%) had MIDP, 30 (10.6%) had conversions and 28 (9.9%) had outpatient department. The risk factors for conversion included large lesion size (heart rates [HR]: 5.632, 95% confidencevinterval [CI]: 1.036–1.450, P = 0.018) and pancreatic cancer (HR: 6.957, 95% CI: 1.359–8.022, P = 0.009). Compared with MIDP, those who required conversion were associated with longer operations (P = 0.003), higher blood loss (P < 0.001) and more severe of the complications (P < 0.001). However, no statistically significant differences were found between the conversion group and ODP. Conclusions: Large lesion size and pancreatic cancer were reported to be independent risk factors for conversion during MIDP. As for post-operative outcomes, the outcomes of successfully MIDP were better than those for conversion. However, conversion did not lead to worsening outcomes when compared with ODP.
