The 30-day morbidity and 90-day mortality rates were retrospectively reviewed among a total of 507 primary bariatric procedures. The early postoperative outcomes of 360 RYGB, 88 SG, and 59 BPD-DS procedures performed during this period were compared.
The patients weighed more in the BPD-DS and SG groups. The SG patients were significantly older than the RYGB and BPD-DS patients. Co-morbidities were significantly more frequent in the SG and BPD-DS patients. One patient died after RYGB but none did so after BPD-DS or SG. The global complication rate was significantly increased after BPD-DS (P = .0017) compared with RYGB; however, no difference was found between RYGB and SG, although bleeding was likely to appear more frequent, not only after BPD-DS, but also after SG compared with RYGB.
Although no fatal outcomes occurred after SG, this procedure did not demonstrate a reduced risk of postoperative complications compared with RYGB with a significantly greater rate of bleeding. RYGB appears to be a relatively safe bariatric procedure, although the groups were not comparable in terms of the preoperative body mass index or co-morbidities, the exact role of which on postoperative morbidity remains controversial. Although the increased risk of RYGB to BPD-DS was confirmed, SG failed to live up to its 鈥渕ore benign鈥?reputation.
