title: Intestinal occlusion through extrinsec stenosis of transverse colon associated with internal right mesocolic hernia.
abstract: BACKGROUND
  The incidence of malrotation has been estimated at 1 in 600 live births. An increased incidence of 0,2% has been found in barium swallow studies, whereas autopsy studies estimate that the true incidence may be high as 1% of the total population. The clinical manifestations are elusive; therefore, the diagnosis must be based on the presence or absence of the acute obstruction. Radiologic investigations, especially those using contrast substances, are the ones used most often in the diagnosis of malrotation. Laparoscopy may give the clinician a valuable tool that will help him diagnose the rotational anomalies and correct the potentially obstructing lesions with minimal surgical trauma to the patient. The role of the surgical treatment is to prevent volvulus and to treat any kind of obstruction. Ladd's procedure provides all the elements for reaching this goal.
  
  
  OBJECTIVE
  The following report describes a particular case of one female patient, 8 years old, admitted in our clinic with signs of intestinal obstruction. She had similar episodes in the last three months, but the symptoms had resolved spontaneously.
  
  
  RESULTS
  Upper gastrointestinal series showed an anomaly of rotation and barium enema discovered a tight stenosis on the transverse colon. Emergency surgery using laparotomy enabled diagnosis. Intraoperatively, a right mesocolic hernia and a transverse colon extrinsic stenosis due to abnormal peritoneal attachments were noted.
  
  
  CONCLUSIONS
  Colon obstruction due to peritoneal bands is extremely rare. The clinical manifestations are not specific and we need radiologic procedures to help diagnose the disease. The cause of the obstruction is not always evident despite the availability of modern imaging techniques. Since preoperative diagnosis is difficult, morbidity and mortality can be decreased by an early surgical intervention.
