  Presentation Top

A 14-year-old male was admitted with the complaints of abdominal distension, constipation, abdominal bloating, and dull-aching abdominal pain for 2 days. There was no history of fever and vomiting. He had not eaten anything for the past 2 days. He had no neurological problems and was not on any medications. Family history was insignificant.

  Assessment Top

On physical examination, the heart rate was 98 bpm, blood pressure 130/82 mmHg, and respiratory rate 18 breaths/min. The abdomen was distended with tenderness in the left iliac fossa region. There was no abdominal thrill. The patient was afebrile. The hemogram profile revealed hemoglobin 12 gm%. The complete blood count, renal function tests, and coagulation profile were normal.

An erect abdominal radiograph was ordered immediately which revealed a large dilated gut loop in occupying more than half of the abdomen with a classic coffee-bean appearance with absent rectal gas [Figure 1].

  Diagnosis Top

The radiographic findings in combination with clinical examination findings were classic for sigmoid volvulus. It occurs due to twisting of the sigmoid colon over sigmoid mesocolon. The sigmoid volvulus is an emergency keeping in mind the consequence of bowel necrosis. The other signs on abdominal radiography are absent rectal gas and Frimann-Dahl's sign (dense lines converging toward site of obstruction).

Other diagnostic modalities used in the diagnosis of sigmoid volvulus are fluoroscopy and computed tomography, but these are time-consuming as they require oral contrast ingestion. These modalities are used when the diagnosis is uncertain on abdominal radiograph.[1]

  Management Top

Colonoscopic detorsion was performed in this patient. The postintervention period was uneventful. This was followed by laparoscopic sigmoidopexy at 2-week interval to prevent recurrent volvulus.

There are multiple treatment modalities available for the sigmoid volvulus. In the acute setting, rectal tube insertion or colonoscopic detorsion form the preferred modalities with a success rate of >90%.[2] In the chronic setting where there is evidence of bowel necrosis or when the medical management is unsuccessful, the management option is sigmoidectomy with bowel anastomosis or colostomy.

The present case was managed conservatively in the emergency setting followed by a preventive laparoscopic sigmoidopexy.
