A 48-year-old male presented with abdominal pain and distension for 5 days. Imaging revealed transverse colon volvulus, which was confirmed during surgery. Transverse colon volvulus is rare, accounting for only 2-4% of intestinal obstructions. It carries a higher mortality risk of 33% compared to 21% for sigmoid volvulus and 10% for cecal volvulus. Surgical detorsion and resection of the affected colon segment is usually required to prevent recurrence.

2. Case Report
• A 48yr old male patient, came to the Radiology
department, referred by Surgery department, SRMC &
GH, with complaints of generalised pain, distension of
abdomen and constipation since 5 days. No h/o
vomitings.
• On examination Bowel sounds were sluggish.
• Patient had no past medical history of chronic
constipation, psychiatric disease, neurologic disease, or
abdominal surgery. All the lab reports were normal.
• The patient was requested X- ray of Abdomen erect.

8. Discussion
• Volvulus is defined as Twist of the bowel around
its own mesentery, there by causing obstruction
to the flow of bowel.
• Only 3 to 5% of all cases of intestinal obstruction
are caused by colonic volvulus.
• Among them, transverse colon is involved in 2 to
4% versus 43 to 80% and 15 to 43% respectively
for the sigmoid colon and the caecum.

11. Forms of presentation
• The literature describes two forms of
presentation; acute fulminating and subacute
progressive.
• Acute fulminating with sudden, severe pain,
little distension and rapid development of shock.
More common in younger patients.
• Subacute progessive with cramping, vomiting,
distension, and gradual deterioration. More
common in Older individuals.

12. Pathogenesis
CONGENITAL PHYSIOLOGICAL MECHANICAL
Redundancy
Non fixation
Long mesentery
High roughage Diet
Elongation and distension 2o
Constipation
Megacolon from Hischsprung’s
disease
Previous volvulus of the transverse or the
sigmoid colon,
Distal colonic obstruction, adhesions,
Malposition of the colon following previous
surgery,
Mobility of the right colon,
Inflammatory strictures,
Carcinoma.

13. • Volvulus of the transverse colon is a rare
cause of intestinal obstruction.
• To our knowledge, only 75 cases have been
reported in the English literature to date.
• No recent reviews of transverse colon volvulus
in adult patients have been published in the
surgical literature since 1983.

14. • Transverse colon volvulus most often occurs in
the second and third decades of life with an
additional peak in seventh decade.
• Women outnumber men 2:1.

15. • Volvulus of the transverse colon can result in
mortality or significant morbidity relatively
more often than caecal or sigmoid volvulus.
• The mortality rate of transverse colon volvulus
is 33%, whereas sigmoid volvulus carries a
mortality rate of 21% and cecal volvulus a rate
of 10%.

16. • Twisting in volvulus usually occurs along the
mesenteric axis of the bowel, resulting in
venous obstruction and eventually arterial
compromise.
• Compression of the duodenojejunal junction
at the root of its mesentery may cause severe
vomiting in this condition.

17. • Volvulus of sigmoid colon is decompressed
colonoscopically, but where as volvulus of the
transverse colon has to be detorsed surgically.
• Resection of the affected segment constitutes
the treatment of choice to prevent
recurrence.

18. Another similar case
• Recently we observed similar findings as in
previous case in a 16 year old female.
• Patient present with complaints of Pain and
distension of abdomen.

23. Conclusion
• Transverse colon volvulus is very rare and causes
high risk of mortality and morbidity than sigmoid
and caecal volvulus.
• Diagnosis can be challenging and the effective
management remains controversial.
• Prompt recognition with emergency intervention
constitutes the key to successful outcome.
