A matched cohort study of laparoscopic biliopancreatic diversion with duodenal switch and sleeve gastrectomy performed by one surgeon.

SETTING

Spectrum Blodgett and Mercy Health St. Mary's hospitals in Grand Rapids, Michigan

OBJECTIVE

To compare the 30-day outcomes of laparoscopic biliopancreatic diversion with duodenal switch (BPD/DS) to laparoscopic sleeve gastrectomy (SG).

BACKGROUND

Laparoscopic BPD/DS has been shown to be superior to SG in terms of excess weight loss. Despite this superiority, BPD/DS accounts for a small percentage of all metabolic surgeries due partly to the perception that BPD/DS has a higher complication rate than SG.

METHODS

Retrospective review of all patients who underwent BPD/DS or SG from January 2008 to August 2014 by 1 surgeon was completed. These patients were used to construct cohorts matched via propensity score matching and compared by surgical type. Data collected included patient demographic characteristics; hospital length of stay (LOS); and 30-day rates of leak, bleed, reoperation, readmission, and mortality.

RESULTS

Of the 741 patients who underwent BPD/DS or SG, 2 cohorts of 167 patients each were matched for age, sex, and BMI. LOS was longer in the BPD/DS cohort (2.5±.9 days versus 2.1±.7 days, P<.001). There were no significant differences between the groups in relation to 30-day postoperative rates of leak (.3% versus .6%, P>.99), bleed (0% versus .3%, P>.99), reoperation (1.2% versus .6%, P>.99), or readmission (3% versus 1.2%, P = .45). There were no mortalities.

CONCLUSION

After matching for age, sex, and BMI, BPD/DS found no significant differences from SG with regard to 30-day postoperative rates of leak, bleed, reoperation, readmission, or mortality.
