Technical and functional results after laparoscopic rectopexy to the promontory for complete rectal prolapse. Prospective study in 54 consecutive patients.

INTRODUCTION: Laparoscopic rectopexy for complete rectal prolapse offers short-term advantages compared with operations performed by laparotomy. The aim of this prospective study was to report technical and functional outcome after laparoscopic rectopexy to the promontory in consecutive patients operated on by a single surgeon. PATIENTS AND METHODS: From May 1996 to July 2004, 54 consecutive patients (47 women), median age 53 years (range: 16-84 years), underwent laparoscopic rectopexy to the promontory for complete rectal prolapse. Preoperative evaluation included physical examination, dynamic videoproctography and, in patients with constipation, colonic transit time (with radiopaque markers). Postoperative evaluation included the same examinations and a simple global quality-of-life questionnaire. RESULTS: Conversion to laparotomy was required for three patients during the learning curve. Median duration of operation was 157 minutes (range: 50-370). There was no mortality and morbidity was 5.5% (brachial plexus palsy in two patients and urinary tract infection in one). Median hospital stay was 3.5 days (range: 1-11). There were 4 recurrences (7.4%). Functional outcome at 12 months showed the presence of constipation in 20.3% of patients (persistence in eight and de novo in three) and the presence of outlet obstruction in 25.9% of patients (persistence in six and de novo in eight). Anal continence improved in 72.4% of the 29 patients who complained of this symptom. The global quality-of-life questionnaire showed a satisfactory result in 96% of patients. CONCLUSION: Laparoscopic rectopexy to the promontory is a safe and efficient procedure to treat complete rectal prolapse; morbidity is low. Functional outcome is at least equivalent to that obtained with open procedures in terms of continence, constipation and outlet obstruction.

Sacral neuromodulation in the treatment of severe anal incontinence. Forty consecutive cases treated in one institution.

INTRODUCTION: Sacral neuromodulation is a recognized therapeutic option in severe anal incontinence from neurogenic origins, when medical treatment has failed. METHODS: We report the results of this procedure applied in 40 consecutive patients operated on by a single surgeon from August 2001 to June 2004. Mean duration of incontinence was 5 years. There were 33 women and 7 men of mean age 59 (range 29-89). All patients had had medical treatment, 26 had had physiotherapy and 9 had been previously operated on for that problem. Neuromodulation consisted in a temporary electrical stimulation test followed by implantation of a stimulator in case of efficacy. RESULTS: Twenty nine patients had a positive test and were implanted. Ten had a negative test and one is waiting for implantation. From the 29 patients, 23 had uneventful postoperative course. Incontinence score varied from 17 before neuromodulation to 6 after in the 24 patients who were improved. Mean resting pressure, mean maximum squeeze pressure and mean duration of squeeze pressure did not change from pre to postoperative period. CONCLUSION: Sacral neuromodulation is a safe and efficacious procedure in properly selected anal incontinent patients. However, we observed no correlation between clinical and manometric data.

Oesophageal motor and sensitivity abnormalities in non-obstructive dysphagia.

OBJECTIVES: To evaluate oesophageal sensitivity to balloon distension in patients with non-obstructive dysphagia (NOD), and to determine its relationship with the motility pattern in response to food ingestion. PATIENTS AND METHODS: Twenty-one healthy volunteers and 19 consecutive patients complaining of NOD with normal standard manometry were included. An oesophageal sensitivity test was carried out before the manometry study with liquid and solid swallows. RESULTS: The median threshold to distension was 9 ml in control subjects and 5 ml in patients (P < 0.002). Dysphagia or odynophagia were reproduced in 15/19 (78.9%) patients during manometry with solid swallows only. The percentage of swallows with abnormal motility patterns was higher in patients than control subjects (P < 0.001). Compared with control values, sensitivity abnormality was defined by a distension threshold of < 6 ml. Motor abnormality was defined by > 19% of swallows occurring with one or more abnormal motor profiles. A total of 8/19 (42%) patients presented with the association of an abnormal sensitivity threshold and an abnormal motor pattern; 5/19 (26%) presented with isolated motor abnormalities; 4/19 (21%) patients presented with isolated abnormal sensitivity thresholds; and 2/19 (11%) patients presented without any abnormality. CONCLUSION: Manometry with solid swallows and oesophageal balloon distension are useful in characterizing NOD.
