Anal manometry and anal electromyography (EMG) were performed in 45 patients to evaluate the external anal sphincter. Their symptoms were soiling (N = 6), incontinence (N = 10), and obstipation (N = 19). Clinical diagnoses were previous anal surgery (N = 16), rectal prolapse--partial, total, intussusception (N = 16), puborectalis syndrome (N = 4), neurologic disorders (N = 3), and others (N = 6). The relationship between the maximum squeeze pressure (MSP) measured with anal manometry and the maximum (voluntary) contraction pattern (MCP) and signs of denervation (DEN) measured with anal EMG were examined. The correlation coefficient between MSP and MCP was 0.55 (P less than .001) and between MSP and DEN 0.13 (NS). A normal MSP always showed a normal MCP, a normal MCP showed an abnormal MSP in 43 percent only. In conclusion, the clinical value of anal EMG seems limited. Assessment of an additional anal EMG seems indicated in incontinent patients with previous anal surgery with a low MSP to estimate muscle function, whenever anal surgery is considered. Anal EMG during straining can easily confirm the clinical diagnosis of puborectalis syndrome.

Faecal incontinence is a disabling condition caused by: (1) sphincter damage caused by childbirth, anorectal surgery, trauma, fistulae and abscesses; (2) pudendal neuropathy ("idiopathic faecal incontinence") caused by stretch injury by long-standing constipation or prolonged labor; (3) diminished rectal compliance in proctitis, low anterior resection or small pouches; (4) faecal impaction causing paradoxal diarrhoea; (5) neurological disease involving the pelvic floor and or the central nervous system; (6) diarrhoea. Often several factors play a role in a patient. A medical history and physical examination will generally provide a reasonable diagnosis. Anorectal function tests can show one or more abnormalities. Anal manometry can show low sphincter pressures; rectal compliance can show a small rectal volume; anal mucosal sensitivity measurement can show a high threshold and neurophysiological tests can demonstrate diminished muscle activity and a delayed pudendal nerve motor latency. Anal endosonography and defaecography have a direct clinical impact. Anal endosonography is a promising diagnostic tool demonstrating sphincter defects, even those not previously suspected. A sphincter defect demonstrated by anal endosonography provides a solid basis for a sphincter repair. Defaecography can reveal an intussusception, which is an indication for performing a rectopexy in the incontinent patient. A suggested work-up of the incontinent patient is given in a table. Besides the classic surgical treatments such as sphincter repair, rectopexy and post-anal repair new (surgical) options have been tried. The most promising new therapy seems the dynamic gracilis repair.

For many patients, bariatric surgery results in enduring weight loss and comorbidity resolution, but it is not without risk of complications. Complications necessitating possible surgical intervention include small bowel obstruction, internal hernia, intussusception, anastomotic ulcer, and anastomotic leak. Medical complications include dumping syndrome; osteoporosis; substance abuse; nephrolithiasis; high suicide rates; and nutritional deficiencies, some of which can result in neurologic disorders. Patients need to take daily multivitamins with minerals (containing iron, copper thiamine, and folic acid), vitamin D, and calcium to prevent nutritional deficiencies. Patients also need to consume 1 to 1.5 g of protein per kilogram of ideal body weight daily. Vitamin levels should be assessed on a regular basis to monitor for deficiencies and prevent neurologic sequelae.
