METHODS: Patients who underwent OHR and LHR between January 2006 and September 2020 in a single center in Japan, were retrospectively evaluated. Patient characteristics and perioperative data were collected from the medical and surgical records and assessed.
RESULTS: Overall, 15 and 19 patients underwent OHR and LHR, respectively, between January 2006 and September 2020. LHR was associated with less blood loss (median: 15 mL vs 185 mL; P < .001) and shorter hospital stays (9 days vs 14 days; P = .023) than OHR. There was no significant difference in postoperative complications between LHR and OHR (26.3% vs 40.0%, P = .475). However, two severe anastomotic complications in LHR were observed in patients with the stump below the peritoneal reflection. No significant difference in outcomes was observed between LHR patients who underwent open and laparoscopic HP.
CONCLUSIONS: LHR resulted in positive outcomes regarding estimated blood loss and postoperative hospitalization, compared with OHR. Although the postoperative complications between LHR and OHR were not significant, patients with the stump below the peritoneal reflection may be at a high risk of anastomotic complications.
