BACKGROUND: Fecal continence is maintained by complex coordination of the sphincter mechanism and the anorectal sensation. Although most patients with fecal incontinence have a dysfunction of anal sphincter, fecal soiling seems to be related with a change in the anorectal sensation. PURPOSE: This study was done to evaluate the manometric findings and the methods of treatment for patients with fecal soiling. METHODS: The manometric findings from 25 patients with fecal soiling were compared with those from 22 normal controls. The patients were treated with biofeedback and with bulking agent. RESULTS: All the patients affected by fecal soiling were male except for one. There were no differences in the mean maximal resting pressure (MRP), and the mean maximal squeezing pressure (MSP) between the patients and the controls. The mean sphincter length and the mean length of the high pressure zone (HPZ) of the patients were significantly longer (50.5 vs. 55.6 mm and 28.2 vs. 31.3 mm, respectively; p<0.05 student t-test) than those of the controls. The minimal sensory volume (MSV) was significantly larger in the patient group, with a mean of 24.2 ml vs. 17.8 ml, than in the control group (p<0.05). The mean volume necessary to induce the recto-anal inhibitory reflex (RR) was 47.1 ml for the control group and 32.6 ml for the patient group (p<0.05). In the longitudinal profile of the anal sphincter, the HPZ was shifted proximally and the pressure peak was broader in the fecal soiling group. Of the 14 patients treated with biofeedback, 11 responded well. CONCLUSION: Almost all of the patients affected by fecal soiling were men. The MRP and the MSP of the patients with fecal soiling were not lower than those of the normal controls. The sphincter length was longer in the patients with soiling than in the controls(p<0.05). However, for the fecal soiling group the distribution of the pressure along the anal canal was different in the sense that the HPZ was shifted proximally and the pressure peak was broader. The changes in the MSV and the RR suggest that there may be a defect in the anorectal sensation. The patients responded well to the combined use of biofeedback and a bulking agent.

PURPOSE: A retrorectal developmental cyst (tailgut cyst, epidermoid cyst, dermoid cyst, teratoma, and duplication) is very rare disease, and the symptoms are not characteristic so that sometimes this disease is still misdiagnosed as a supralevator abscess or a complex anal fistula. We would like to present a clinical approach to this disease. METHODS: We retrospectively examined the charts of 15 patients who were treated for retrorectal cysts from January 2001 to November 2009. RESULTS: All 15 patients were female. The average age was 41 years (range, 21 to 60 years). Fourteen patients (93.3%) were symptomatic, and the most common symptom was anal pain or discomfort. Nine patients (60%) had more than one previous operation (range, 1 to 9 times) for a supralevator abscess, an anal fistula, etc. In 12 patients (80%), the diagnosis could be made by using the medical history and physical examination. Thirteen cysts (80%) were excised completely through the posterior approach. The average diameter of the cysts was 4.8 cm (range, 2 to 10 cm). Pathologic diagnoses were 8 tailgut cysts (53.3%), 5 epidermoid cysts (33.3%) and 2 dermoid cysts (13.3%). The average follow-up period was 18.3 months (range, 1 to 64 months). CONCLUSION: In our experience, high suspicion and physical examination are the most important diagnostic methods. If a female patient has a history of multiple perianal operations, a retrorectal bulging soft mass, a posterior anal dimple, and no conventional creamy foul odorous pus in drainage, the possibility of a retrorectal developmental cyst must be considered.

Rhabdomyolysis is a syndrome involving the breakdown of skeletal muscle, and this causes myoglobin and other intracellular proteins and electrolytes to leak into the circulatory system. We report here on a case of rhabdomyolysis associated with statin, exercise and sauna exposure. A 63-year-old woman presented to our hospital, and she had been taking simvastatin for over 6 years due to dyslipidemia. She complained of developing myalgia and weakness of the lower extremities over the previous 5 days. She had used a sauna more than 4 hours daily for 20 years, and she had started unaccustomed exercise in the sauna 1 week prior to admission. Her serum creatine kinase concentration was 45,990 IU/L. Conservative treatment was started with the discontinuation of her statin medication, exercise and use of the sauna. Her symptoms and serum creatine kinase level decreased 1 week after admission and she was discharged with minimal residual muscle weakness.
