Anomalous course of the sigmoid colon and the mesosigmoid encountered during colectomy. A case report of a redundant loop of sigmoid colon

Abstract

HighlightsA redundant sigmoid colon is defined as one that is too long to fit into its owner’s body without undergoing reduplication.It is associated with acute and chronic pathological conditions, sigmoid volvulus and serious confusions in radiological diagnosis and instrumentation of imaging procedures.Surgeons, obstetricians and radiologists ought to be aware of this variation and to emphasize to the correlation between gross and clinical anatomy, since their awareness determines the outcomes of an operation and the accurate radiographic diagnosis.

Appendicitis mimicry of dolichocolon

“…There are no standard algorithms for dolichocolon management at this time. However, based on the early onset clinical, radiographic, and objective measurements of dolichocolon, clinicians should have a high suspicion for dolichocolon to provide accurate and appropriate intervention in a timely manner, to which future algorithms must be generated to support this cause [ 14 , 15 ].…”

Right-side fixation of the sigmoid colon causing internal herniation with closed-loop obstruction of both small and large bowel: a case report and review of the literature

“…However, only the case described by Komiyama appears to have anatomic features analogous to the present case. A course of the sigmoid colon below the mesenteric plane has also been described [ 10 ]; in this case, the sigmoid loop ran posterior to the root of the mesentery. Interestingly, while no specific link has been described with right-side fixation of the sigmoid colon, renal ectopia has been associated with intestinal malrotations [ 11 ].…”
