Chilaiditi's syndrome. Successful surgical correction by colopexy.

We describe the case of a patient affected by the Chilaiditi's syndrome, the interposition of the small or large bowel between the inferior face of the diaphragm and the liver, a rare anomaly, often asymptomatic. A 50-year-old man came to our outpatients clinic because of persistent pain in the right abdominal region. Two attempts to perform colonoscopy failed because of the impossibility of passing through the transverse colon. A double contrast enema indicated only sigmoid diverticulitis. Only after abdominal radiography was the abnormal position of the right colon noted. At surgery the right colon was totally intraperitoneal and positioned between the diaphragm and liver, which was smaller than normal. The right colon was repositioned and fixed to the anterior abdominal wall. The postoperative course was uneventful and the right abdominal pain disappeared completely. In conclusion, surgical treatment of Chilaiditi's syndrome may be required in cases of persistent abdominal pain.

Electrostimulated gracilis neosphincter for faecal incontinence and in total anorectal reconstruction: still an experimental procedure?

The possibility of converting an easily fatiguable muscle like the gracilis muscle into a fatigue-resistant one using chronic electrostimulation has renewed interest in Pickrell's procedure. Between July 1991 and June 1996, 9 patients (2 M; 7 F) mean age = 45 y (range 14-72) underwent dynamic graciloplasty using Medtronic electrostimulators. Five patients had faecal incontinence (2 congenitally anomaly, 1 neurological, 2 post-operative) and 4 had a perineal colostomy performed either simultaneously (two cases) or at 3 to 4 years after abdominoperineal excision of the rectum. Early post-operative complications included distal tendon necrosis [1], perineal colostomy breakdown [1], detachment of the gracilis tendon [2] and seroma in the thigh [1]. Long-term complications included rectocele with faecal impaction in one patient with imperforate anus, anal stricture in one patient who had refashioning of a perineal colostomy, and displacement of the lead from the main nerve in 3 with external expulsion in 2. The patient with anal stricture was successfully treated with anoplasty but subsequently returned to an abdominal colostomy due to stricture recurrence 2 years later. The rectocele was successfully treated using a transvaginal approach. Electrical conversion of the muscle was completed in all patients but long term functional results are available for only 5 cases. Manometry revealed a significant improvement in anal pressure under electro-stimulation and the continence grading scale score significantly improved in 4 patients. The technique is applicable to a very selected group of patients with no other options but is still in the experimental phase and should not be performed outside controlled trials. Repeated hospitalisation and reoperations are often required although the complication rate may diminish and improve with experience.
