Early Outcomes of Different Reconstruction Procedures in Radical Distal Gastrectomy: A Retrospective Propensity Score...

To evaluate the short-term effects of Billroth I (B-I), Billroth Ⅱ (B-Ⅱ), Billroth Ⅱ+Braun (B-B), and Roux-en-Y (R-Y) reconstruction procedures in radical distal gastrectomy using propensity score matching (PSM).

The clinical data of 1994 patients who underwent radical distal gastrectomy in the past 10 years were retrospectively analyzed. Subsequently, PSM analyses were performed 3 times on the 4 reconstruction procedures, and the matching capacity was set to 0.01. Data regarding control variables and outcome indicators obtained using PSM were compared and analyzed.

Compared with the other reconstruction procedures, patients in the B-I group had shorter operation time ( P =0.002), fewer abdominal drainage tubes ( P <0.001), and a lower risk of postoperative gastroparesis ( P =0.001) and gastrointestinal bleeding ( P =0.034), but tended to experience a longer postoperative indwelling time of bladder catheter ( P <0.001), gastrointestinal decompression ( P <0.001), fasting ( P =0.001), and hospital stays ( P =0.005). The B-B group tended to have fewer applications of the abdominal drainage tube ( P =0.014), a lower risk of postoperative gastrointestinal fistula ( P =0.040), shorter postoperative time of gastrointestinal decompression ( P =0.043), fasting ( P <0.001), and a shorter hospital stay ( P <0.001) than the R-Y group. Furthermore, the B-B group had a shorter postoperative time for gastrointestinal decompression ( P =0.014) and fasting ( P <0.001) than the B-Ⅱ group.

Billroth I reconstruction has the advantages of simple operation, short operative time, and few early complications, but tends to result in a long recovery time during postoperative hospitalization. The B-B operation is associated with faster postoperative recovery than the R-Y or B-Ⅱ operation.
