Transanal irrigation in functional bowel disorders and LARS: short-term results from an Italian national study.

PURPOSE: To evaluate the potential benefits associated with the short-term (6 months) treatment with transanal irrigation (TAI) in patients suffering from functional constipation (FC), functional fecal incontinence (FI), and low anterior resection syndrome (LARS). METHODS: A multicenter observational study (12 centers; 369 patients) was conducted to assess the following primary and secondary objectives: to evaluate the level of satisfaction regarding bowel control and quality of life (QoL); to evaluate bowel symptoms severity and dropout frequency and reason. To this aim, validated questionnaires were provided to the patients at baseline (T0) and after 6 months of TAI treatment (T6) performed with the medical device Peristeen® Plus (Coloplast A/S, Denmark). Statistical analyses were conducted to compare the outcomes obtained at T0 and T6. RESULTS: A 6-month treatment with TAI enabled a statistically significant (p < 0.05) improvement of QoL scores, satisfaction scores regarding bowel control, and severity indexes of disorder-related symptoms in patients suffering from FC, FI, and LARS. Globally, 8.0% of patients discontinued the treatment after 6 months as a result of occurrence of symptoms (2.4%) or other justifications (3.8%) such as personal reasons. None of the dropouts were due to treatment inefficacy. CONCLUSION: Results of the present study suggest that short-term TAI treatment is beneficial for patients suffering from functional bowel disorders and LARS. Future analysis of prospective data will focus on the clinical outcomes associated with the long-term use (up to 24 months) of TAI when dealing with these types of medical conditions.

Left colon resection with transrectal specimen extraction: current status.

BACKGROUND: Full laparoscopic left colectomy with transrectal specimen extraction is proposed as an improvement of the minimally invasive surgical technique. This paper reviews in detail the current status of left-sided colectomy and upper rectum resection with transrectal specimen extraction. METHODS: A systematic review was performed of all types of publications on colorectal resection with natural orifice specimen extraction (NOSE). We only included studies reporting on left colectomy, sigmoidectomy, and high anterior resection with transrectal specimen extraction (TRSE), excluding transanal (TASE), transvaginal, or transcolonic specimen extraction. Surgical techniques, patient characteristics, and outcomes were reviewed in detail. RESULTS: Thirty-five papers reported on TRSE (2 randomized clinical trials, 7 case-matched series, 19 case series, 5 case reports, and 2 articles on surgical technique). We found a wide variety of innovative anastomotic and specimen extraction techniques. After excluding duplicates and papers reporting mixed TRSE and TASE results, outcomes in patients undergoing TRSE from 23 publications showed a conversion rate to conventional laparoscopy of 3.7% (21/559), overall morbidity 9.5% (53/559) [major in 2.9% (16/559), intra-abdominal infection in 2.1% (12/559)]. No mortality was reported. Postoperative anal incontinence was rarely reported. Several studies showed a decrease in postoperative pain and some in length of hospital stay. CONCLUSIONS: Colectomy with TRSE is feasible and seems safe in selected patients. Reported outcomes seem in general similar to conventional laparoscopic colectomy with a possible benefit in postoperative pain and length of hospital stay. Obvious selection bias and lack of high quality trials do not allow firm conclusions to be drawn.
