Transanal endoscopic microsurgery for correction of rectourethral fistulae.

BACKGROUND: Rectourethral fistula is a rare complication of radical prostatectomy. Transanal endoscopic microsurgery (TEM) is a minimally invasive technique available for its surgical correction, although currently, TEM is used more commonly for excision of adenomas and stage T(1) carcinomas of the rectum. PATIENTS AND METHODS: We report two patients with rectourethral fistulae after laparoscopic radical prostatectomy in whom TEM was used for closure. The surgical procedure included microscopic full-thickness excision of the rectal wall around the fistula with a 1-cm margin and endoscopic suturing of the defect in the urethral and rectal walls. RESULTS: In one case, the rectourethral fistula was closed using TEM. In the other patient, the procedure, performed after failure of a graciloplasty, was difficult because of extensive scar tissue, and the fistula persisted. CONCLUSIONS: The TEM procedure is a minimally invasive technique that may be considered for surgical repair of rectourethral fistulae.

The effects of spinal cord stimulation on quality of life in patients with therapeutically chronic refractory angina pectoris.

Objective. For patients with refractory angina pectoris, spinal cord stimulation (SCS) is a beneficial and safe adjuvant therapy. However, it has not yet been established whether SCS alters the quality of life (QoL) in these patients. Methods. In this study, 26 consecutive patients (age 61.3 ± 7.0 years, 13 females, angina duration 12.7 ± 6.0 years) were recruited. Social, mental, and physical aspects of QoL were determined by Nottingham Health Profile (NHP I), depression scale (CES-D), scoring of angina pectoris attacks and short-acting nitroglycerine intake, pain score on the Visual Analog Scale (VAS), perceived health percentage, Satisfaction With Life scale (SWLS), and one-aspect Linear Analog Self Assessment scale (LASA). QoL outcomes at baseline were compared with reference values from healthy subjects. Within-group changes and magnitude of changes (effect size, ES) were assessed after 3 months and 1 year of SCS. Results. Compared to healthy subjects, the patients had significantly worse scores at baseline on NHP, SWLS, and LASA. After 3 months of SCS, NHP I aspect pain (ES = 1.39), AP-score (ES = 0.85), perceived health percentage (ES =- 0.80), NTG-use (ES = 1.08) and VAS-score (ES = 1.13) were all significantly improved (p < 0.05). After 3 months, moderate changes were observed; however, they were not statistically significant on the NHP-aspects "emotion" (ES = 0.57) and "sleep" (ES = 0.56). At the 1-year follow-up, significant and substantial improvements were found on NHP-I aspects: pain, energy, emotional reactions, social isolation, sleep, and physical mobility (p < 0.05) with changes that can be interpreted as large (ES > 0.80). Conclusion. QoL in patients with refractory angina pectoris is poor. Both pain and health aspects of QoL improved significantly after 3 months of SCS. Social, mental, and physical aspects of QoL were found improved after 1 year of SCS.
