[Comparative study on four different reconstruction procedures after total gastrectomy].

Objective: To investigate the optimal reconstruction technique after total gastrectomy.

Methods: A total of 159 patients with gastric cancer undergoing total gastrectomy in Tianjin Cancer Hospital between January 2005 and December 2007 were divided into 4 groups according to the reconstruction technique: group A(functional jejunal interposition with a pouch, n=46), group B(modified Braun type II(, n=38), group C (P pouch with Roux-en-Y esophagojejunostomy, n=25), group D(Roux-en-Y esophagojejunostomy, n=50). Quality of life(QOL), nutritional status 1 year after surgery, and perioperative complications were analyzed.

Results: There were no significant differences in perioperative complications(P>0.05). One year after operation, QOL(Visick index) was better in group A than that in group B, C and D(P<0.05), and group D was inferior to group A, B and C(P<0.05). The increase in food intake, weight gain, hemoglobin and total protein were better in group A than those in group B, C and D(P<0.05) and group D was inferior to group A, B and C(P<0.05). The prognostic nutrition index ratio of the four groups were 1.21±0.15, 1.14±0.97, 1.15±0.16, and 1.10±0.16, respectively. Group A was better than that in group B, C and D (P<0.05) and group D was inferior to group A, B and C(P<0.05). The incidences of dumping syndrome, reflux esophagitis, Roux-en-Y stasis syndrome in group A were 4.3%(2/46), 2.2%(1/46) and 2.2%(1/46), respectively, which were significantly lower than those in other groups (P<0.05).

Conclusions: Functional jejunal interposition with a pouch is associated with improved nutritional condition and quality of life, and less perioperative complications. It is a reasonable reconstruction method after total gastrectomy.
