Ileosigmodi investigations were normal apart from leukocytosis total count: Type I, the ileum active component wraps itself around the sigmoid colon passive component in a clockwise or anticlockwise direction type A when clockwise and type B when anticlockwise. Therefore, intestinal clamps should be applied before dissection or resection of the knot followed by resection of both the loops.

An additional recent cases in the English literature are reviewed as to etiopathogenesis, presentation, diagnostic modalities, surgical interventions and outcome. This article has been cited by. Management The initial management involves aggressive resuscitation with fluid and electrolytes and the ileosig,oid of acid-base imbalance if any.

ISK is an unusual entity in the West, but is ileoskgmoid common in certain African, Asian and Middle Eastern nations, known as ‘volvulus belt’. Ileosigmoidal Knotting in Children: Further peristalsis forms an ileosigmoid knot with two closed loop obstruction, one in the small bowel and other in the sigmoid colon.

Atypical Presentation of Ileo-Sigmoid Knot: A Rare Case

Parker [ 1 ] is credited with having described the first case of ISK. Turk J Med Sci. Two cases of ileosigmoid knot: The radiographic findings of ISK, which include a double loop of dilated sigmoid shadow and multiple air fluid levels in the small intestine, are sporadically described and are difficult to identify as such because of unfamiliarity.

Its treatment is different from a simple volvulus in that it has to be operated upon immediately. Preoperative diagnosis is difficult and it is associated with high morbidity and mortality. The distal stump can be closed and end-to-side ileocecostomy can be performed as safer option.


The ileosigmoid knot.

Discussion Overall a rare entity, ileosigmoid knot is more common in Asia, Africa and the Middle East than in the West. Management of Ileosigmoid knotting.

Table 2 Predisposing factors and pre-operative investigation done for diagnosis as by various ileoeigmoid. Timely intervention is needed as it is a closed loop obstruction and that rapidly progresses to peritonitis and gangrene. B Caudal CT scan section shows the whirl sign within the circle created by the twisted mesentery and bowel branches arising from the superior mesenteric artery are present in the whirl.

Related articles Compound volvulus; ileosigmoid knot; intestinal ileosignoid. None, Conflict of Interest: The various surgical procedures ileosigoid in the past and present include:. In conclusion, the ileosigmoid knot is a rare but life-threatening cause of closed-loop intestinal obstruction. Aggressive fluid resuscitation, preoperative antibiotics, prompt laparotomy, effective surgery including resection of gangrenous bowel with or without primary anastomosis, and better perioperative care of the shocked patient have optimized the survival of these patients.

A further caudal CT scan D shows fluid-filled ileal loops in the pelvis with thin non-enhancing walls solid arrow and free fluid present in the pelvic cavity dotted arrow.

Despite the critical condition, preoperative diagnosis is not easy. Since then, over cases knlt been reported in English literature [ 611141617 ]. In spite of early judgment for prompt surgical intervention, the higher rates of both gangrene and mortality seem paradoxical and presumably reflect the fulminating clinical deterioration of patients due to early and extensive infarction of the bowel involved in a tight knot.

Summary ISK is a rare yet life-threatening cause of acute intestinal obstruction. Indian J Radiol Imaging. Ileosigmoid knotting, also known as compound volvulus or double volvulus, is a rare cause of intestinal obstruction. The diagnostic difficulty is partly caused by the unfamiliarity ileosigmojd this rare entity and the confusing and self-contradictory features of the disease.


Ileosigmoid knot – Wikipedia

This is a surgical emergency that requires urgent resection of gangrenous bowel and untwisting of the volvulus. A year-old male patient with a history of chronic constipation was admitted with severe lower abdominal pain of hour duration. On examination, there was mild tenderness in the periumbilical and right lumbar region. CT scan reveals the classical “whirl sign” of volvulus, created by the twisted mesentery and bowel, and the afferent and efferent limbs of the sigmoid colon have the appearance of a beak [ 25 ].

Alver, 68 49 Resection of the sigmoid colon is often advised in all instances even when it is viable. The findings in a CT scan suggestive of ISK include the whirl sign created by the twisted intestine and sigmoid mesocolon in ileosigmoid knot, medial deviation of the cecum, and descending colon.

This condition is common in east Africa, particularly among the young males of the Baganda tribe. It is difficult to diagnose this condition before surgery. Recurrent volvulus or repeat knotting due to redundancy of the loop may cause gangrene after surgery.

On exploration, minimal hemorrhagic peritoneal fluid was noted. Journal of Surgery [Jurnalul de chirurgie]. Better understanding of the problem, and increased probabilities of preoperative diagnosis with aid of CT scanning, have facilitated early diagnosis and intervention.

Kakar A, Bhatnagar BN. Prompt treatment is mandatory. However, recent data suggest that primary colonic anastomosis may be undertaken safely when the history is short and the remaining bowel is clean, well vascularized, and undistended. Plain film of the abdomen showed dilatation of the small intestine with a gas and air fluid level, with an associated moderately distended, and obstructed sigmoid loop.

The direction of torsion is clockwise in
