So, does this mean, in English, that it is more effective for weight loss to have a SHORTER common channel.....?

 Seattle, WA Duodenal Switch (09/30/05) Member Since: 04/08/05[Latest Posts] | Post Date: 12/11/07 10:35 pm It is hard to make out but I think what it is saying is that the ratio between the Biliopancreatic limb and the Alimentary limb is important for long term maintenance in patients with higher BMIs. It says this was less important for those with lower BMIs. It does not mention the common channel at all so I am guessing that was not part of the study. Laura H. HW=305, LW=152, GW=160-170, CW=183 |

 IN Duodenal Switch (04/04/08) Member Since: 03/28/07[Latest Posts] | Post Date: 12/12/07 7:34 am I just saw Dr. Anthone on Monday and asked him about his common channel length. To add to what you said... He measures to get the cc length. He takes a certain percentage, I can't remember what it is. But his cc's seem to be longer than the average DS surgeon. My old surgeon just did a standard 100 cc. Dr. A's have been anywhere from 100-200, according to what he said. I asked if he felt like a longer cc meant a slower weight loss, and he said no. Weight loss was more related to the other parts of the surgery. He felt with a slightly longer cc, the patient had much less trouble with nutritional difficiencies and gas and bowel issues. Or something like that!! Mandy ***See my blog for appeal info*** |

Kirkland, WA Duodenal Switch (07/31/07) Member Since: 02/04/05[Latest Posts] | Post Date: 12/12/07 1:34 am Who, me? Alimentary = 280 cm Common Channel = 75 cm No indication on Surgical Report of Biliopancreatic Limb length. At all. When I asked my surgeon what my limb lengths were, all three of them, he said he had not removed any of my small intestine, Alimentary and CC as above, and not to worry about the BP Limb length as it didn't make any difference, since it did not absorb anything (postop) anymore. I'll go look for average small intestinal lengths online, to try to come up with an average for myownself. Looks like my surgeon did not measure it while in there. |

Kirkland, WA Duodenal Switch (09/15/05) Member Since: 05/22/05[Latest Posts] | Post Date: 12/12/07 8:06 am Average is 500 cm. But people can vary greatly. Some are in the 350 range (which obviously you are not, since you have 355 cm in the above numbers). Mine, on the other hand, was 800 cm. I think the longest is like 1200. --BT Four years postop.

Kirkland, WA Duodenal Switch (09/15/05) Member Since: 05/22/05[Latest Posts] | Post Date: 12/12/07 8:59 am So your alimentary limb is 205 and your common channel is 75? Four years postop.

 Atlanta, GA Duodenal Switch (08/30/06) Member Since: 11/17/05[Latest Posts] | Post Date: 12/12/07 5:31 am Last Edit: 12/12/07 6:37 am Good stuff, Sami! I think a bit of the abstract got truncated or was updated. Here is what I copied from PubMed and highlighted the sentence in question: BACKGROUND: It is commonly believed that weight loss after biliopancreatic diversion/duodenal switch is inversely related to the length of the alimentary limb and the common channel. However, the effect of the biliopancreatic limb length (BPL) on weight loss has received little attention. METHODS: A total of 1001 patients after biliopancreatic diversion/duodenal switch (209 men and 792 women, mean age 42 +/- 10 yr, mean body mass index [BMI] 52 +/- 9 kg/m(2)) were divided into 2 groups according to the ratio of the BPL to the total small bowel length (SBL): a BPL <=45% of the SBL versus a BPL >45% of the SBL. The nutritional parameters and percentage of excess weight loss were compared between the 2 groups. RESULTS: In patients with a BMI of <=60 kg/m(2), the percentage of excess weight loss at 1 year postoperatively was 66.8% for those with a BPL <=45% of the SBL and 69.3% for those with a BPL >45% of the SBL (P = NS). At 2 years, the corresponding percentages were 73.7% and 79.5% (P = NS) and, at 3 years, were 73.4% and 75.2% (P = NS). In patients with a BMI >60 kg/m(2), the corresponding percentages of excess weight loss was 56.8% versus 61.4% (P = .07) at 1 year, 62.2% versus 77.5% (P = .04) at 2 years, and 59.8% versus 77.5% at 3 years (P = .05). CONCLUSION: The results of our study have shown that amount of weight lost after biliopancreatic diversion/duodenal switch is directly related to the proportion of small bowel bypassed in patients with a BMI >60 kg/m(2). Also, the effect increased with the duration of follow-up. In less heavy patients, the BPL/SBL ratio had a minimal effect on long-term weight loss and a more pronounced effect on nutritional parameters. --- To calculate the ratio you divide your biliopancreatic limb length by your total small bowel length. My BPL is 510cm, SBL is 760cm for a ratio of 0.671 or 67.1 %. My starting BMI was 71 so that bodes well for me ... according to this study, anyway. 516.6/232.2/180- 284.4 lbs down!

Atlanta, GA Duodenal Switch (08/30/06) Member Since: 11/17/05[Latest Posts] | Post Date: 12/12/07 12:37 pm I believe what it's saying is that for DSers with BMI's over 60 and who have more than 45% of their small bowel bypassed, the greater the loss and a higher rate of maintaining that loss over time. In an indirect way, it's also saying that you really have to look beyond the length of your common channel... I think. 516.6/232.2/180- 284.4 lbs down!

 Ottawa, Canada Duodenal Switch (02/22/08) Member Since: 10/18/07[Latest Posts] | Post Date: 12/12/07 11:32 am I too was struggling with this report. When I went to see Dr. Lu last week he did some mathematical calculation and I believe he said my cc would be 78.  Is this good or bad? HW 265/ SW 250/ GW 140/ CW 120 |
