Figures

Figure 1
Figure 1
Barium enema of the patient with functional constipation (a) and the scheme to it (b). A significant portion of the extended and elongated sigmoid colon is located to the right of the midline (black line) and it is partially superimposed on the cecum. The configuration (red line) of the sigmoid colon differs from the ascending colon configuration. On Figures 2 and 3, it is mistakenly taken as the right half of the colon. Thus, the left half of the colon is in the right half of the abdomen

Figure 2
Slow evacuation from the stomach (g). Dyskinesia duodenum (d). Note the location of the hepatic flexure of the transverse colon (t). Extended rectum (r). Through 120 h, after emptying the rectum, the labeled chyme moved from the transverse colon to the dolichosigma. Conclusion: obstructive constipation (my notation and interpretation in the figure from the article)
Figure 3
Figure 3
My tagging. Slow evacuation from the stomach (g). The small intestine loops conglomerate (s) is located to the left of the cecum. The cecum and ascending colon must be located to the right of the yellow line. Although the sigmoid colon (sig) is located to the right of the midline (white line), it does not reach the location of the ascending colon. Its shape does not even resemble the hepatic flexure of the transverse colon
