Changes in gallbladder motility and gallstone formation following laparoscopic gastric banding: RESULTS (Part 3)
Obese patients six weeks after surgery
Of the 14 patients enrolled at the beginning of this study, three developed gallstones, while three others elected not to continue in the study. The BMI decreased in the remaining 11 patients from 44.5±3.2 to 40.4±2.8 (or 1.4±0.1% body weight per week), from that recorded preoperative ly compared with six weeks following surgery, respectively. In these obese patients, the fasting gallbladder volume decreased 25%, from 43.0±6.6 mL before surgery to 29.1 ±6.1 mL at the sixth postoperative week, respectively (Figure 1A).
They also experienced a significant reduction in gallbladder emptying, from 80.3±3.9% to 65.5±6.9% (P< 0.05) (Figure 1B). Their emptying remained less than that of the volunteer control (P<0.05). This decrease in gallbladder emptying allowed the gallbladder residual volume to increase by one-third, from 8.3±4.5 mL to
11.2±4.5 mL, between the preoperative and six weeks postoperative measurements, respectively. Although this increase in residual volume did not reach significance (Figure 1C), all values remained higher than those in the control group (P<0.05). Gallbladder refilling decreased 39.5%, from 0.43±0.09 mL/min to 0.26±0.04 mL/min between the preoperative and six weeks postoperative measurements respectively, at a significance of P=0.07 (Figure 1D). Refilling remained well above the volunteer group (P<0.05).
