Objective:
To investigate the emptying of solids after total gastrectomy with pouch reconstruction.
Design:
Randomised, prospective study.
Setting:
University hospital, Finland.
Subjects:
49 patients with gastric carcinoma operated on for cure between 1988 and 1992.
Interventions:
After total gastrectomy 26 patients were randomised to have a pouch reconstruction and 23 a Roux-en-Y reconstruction. 15 months after the operation 24 patients with a pouch (pouch group) and 21 patients with a simple Roux-en-Y reconstruction (Roux-en-Y group) were alive and available to have an emptying test by the solid isotope method. Emptying of the pouch and Roux-en-Y limb was assessed by measuring the activity at 3 hours.
Main Outcome Measures:
Postoperative symptoms, size of meal, and postoperative nutrition.
Results:
Emptying was significantly slower after pouch reconstruction than after Roux-en-Y (mean activity at 3 hours 82% and 44%, respectively, p < 0.01). Early satiety occurred in 10 (48%) of the patients after Roux-en-Y reconstruction and 6 (25%) in the pouch group. Dumping was more common in the Roux-en-Y group (n = 12, 57% compared with n = 6, 25%, p = 0.04). 19 (79%) of the patients in the pouch group were able to eat normal sized meals compared with 3 (14%) in the Roux-en-Y group (p < 0.0001). Weight gain and haemoglobin and albumin concentrations were similar in the two groups.
Conclusion:
Jejunal pouch reconstruction after total gastrectomy delays passage of solid food in the upper intestine compared with Roux-en-Y reconstruction. It is associated with better eating capacity and fewer postoperative symptoms.
