Background/AimsColon transit time (CTT) is a useful diagnostic tool in chronic constipation, but requires good patient compliance. We analyzed the correlation between the gas volume score (GVS) and CTT in patients with chronic constipation. MethodsThe study included 145 consecutive patients (65 men) with chronic constipation. The primary outcome was the correlation between the colon GVS and CTT. Secondary outcomes were the differences in colon GVS according to CTT and subtypes of chronic constipation. ResultsThere were 81 patients with "CTT < 45 hours" and 64 patients with "CTT ≥ 45 hours." In addition, 88 patients were classified as having functional constipation and 57 were classified as having constipation predominant irritable bowel syndrome (IBS-C). There was no significant correlation between CTT and colon GVS. However, the right colon GVS showed a positive correlation with right CTT (r = 0.255, P = 0.007). The median total colon GVS was significantly higher in patients with "CTT ≥ 45 hours" than in those with "CTT ＜ 45 hours" (5.65% vs 4.15%, P = 0.010). There were no significant differences in colon GVS between the functional constipation and IBS-C. ConclusionsWe were unable to detect a correlation between GVS and CTT in patients with chronic constipation. However, total colon GVS may be a method of predicting slow transit in patients with chronic constipation.

“…In addition, the systematic review identified eight papers that examined intestinal transit in the presence of methane (Table 2) [39][40][41][42][43][44][45][46]. While studies could not be combined for meta-analysis due to markedly different techniques (bowel frequency, orocecal, colonic, and whole gut transit time), all eight studies demonstrated that the presence of methane was associated with significant slowing of intestinal transit irrespective of the measure used.…”

Intestinal gas in plain abdominal radiographs does not correlate with symptoms after lactulose challenge

Abstract: Intestinal gas volume, as scored in plain abdominal radiographs, is not correlated with abdominal discomfort after lactulose challenge. Intestinal gas may not be the major cause of abdominal discomfort following carbohydrate ingestion in patients with functional gut disorders.
