Review of 68 cases. USG revealed dilated fluid-filled small bowel loops and free fluid in pelvis. Better understanding of the problem and increased probabilities of preoperative diagnosis with the help of contrast-enhanced computed tomography scanning have facilitated early diagnosis and intervention.

However, CT examination may not be possible in all patients because of nonavailability or some patients could be in a very poor condition. It can rapidly progress to gangrene of the ileum as well as of the sigmoid colon that may result in fatal complications such as, generalized peritonitis, sepsis, dehydration, and electrolyte imbalance. October 02, Citation: The usual antibiotic combination includes cephalosporins, aminoglycosides, and metranidazole.
Open in a separate window. The mortality figures are generally related to the duration of symptoms, the presence or absence of gangrene and the general status of the patient, including the presence of septicemic shock. Ileosigmoid knotting, also known as compound volvulus or double Volvulus, is a rare cause of acute intestinal obstruction.
The ileosigmoid knot.
Home Publications Conferences Register Contact. Patient was allowed enteral nutrition on 3 rd postoperative day and was supplemented with multivitamins vitamin B The empty loops of ileum and distal jejunum twist in a clockwise rotation around the base of a narrow sigmoid colon.
Both strangulation and thrombosis of the vessels due to increased intramural pressure because of the closed-loop obstruction contributed to ischemia and gangrene of long segment of bowel except 10 cm of non-gangrenous ileum.
Alver, 68 49 Patient was in hypovolemic shock, so resuscitated immediately. If both iloesigmoid are viable, the knot may be undone by sigmoid enterotomy and traction of the sigmoid loop may be performed. Support Center Support Center. The long arrow points to the knot while the short arrows point to the medial displacement of the descending colon and cecum.
Introduction Ileosigmoid knot also known as compound volvulus is an unusual and rare cause of intestinal obstruction. CT scan plays a major role in the evaluation of any acute abdomen. On exploration, minimal hemorrhagic peritoneal fluid was noted.
Although clinical features such as vomiting suggest small bowel obstruction, the radiographic findings are that of colonic obstruction, which is uncommon in small bowel obstruction [ 468 ].
Patient presented with vomitings and obstipation. American journal of roentgenology Visit for more related articles at Journal of Surgery. Knof Sciences Journals Ann Jose ankara escort.
After hemodynamic stabilization, laparotomy should not be delayed.
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. Further peristalsis forms an ileosigmoid knot with two closed loop obstructions Fig. ISK can rapidly progress to gangrene of the ileum as well as of the sigmoid colon.
In conclusion, the ileosigmoid knot is a rare but life-threatening cause of closed-loop intestinal obstruction. In this condition the ileum wraps around the base of the sigmoid colon and forms ilsosigmoid knot.
Intraoperative photographs show a distended sigmoid colon solid arrow and gangrenous ileal loops dashed arrow wrapped around each other forming an ileosigmoid knot.
Kakar A, Bhatnagar BN. Avoiding a colostomy is always welcome, as it reduces the morbidity and cost of health care.

Complications and diagnosis of Meckel’s diverticulum in patients. Besides the above anatomic prerequisites, the literature reveals the evidence of other secondary causative factors including late pregnancy, transmesenteric herniation, Meckel diverticulitis with a band, ileocecal intussusceptions, and floating cecum Table 2. Sign in to save your search Sign in to your personal account. A gangrenous loop of ileum encircling base of loop of gangrenous sigmoid colon was found Figure 2.
Published online Nov In the recent years, contrast-enhanced computed tomography is emerging as a sensitive tool for the diagnosis of ISK. Discussion Overall a rare entity, ileosigmoid knot is more common in Asia, Africa and the Middle East than in the West. The presence of the whirl sign on CT scan — medially deviated distal descending colon and cecum, with mesenteric vascular structures from the superior mesenteric vessels converging toward the sigmoid colon — can help clinch the diagnosis.
Abdominal examination revealed guarding and rebound tenderness without any audible bowel sounds. The anatomical and pathological changes dictate the operative procedure. The mortality figures are generally related to the duration of symptoms, the presence or absence of gangrene and the general status of the patient, including the presence of septicemic shock [ 2 — 711 ileosigmoud.
