(Wiely-Blackwell, 2019) Chandrasinghe, P.; Carvello, M.; Wasmann, K.; Tanis, P.; Warusavitarne, J.; Spinelli, A.; Bemelman, W.
AIM:The novel transanal approach to ileal pouch-anal anastomosis (ta-IPAA) provides better exposure with lower short-term morbidity in ulcerative colitis (UC). The aim of this study was to assess the long-term outcomes after ta-IPAA versus abdominal IPAA (abd-IPAA) in UC. METHOD:This is a multicentre cohort analysis between March 2002 and September 2017. Patient characteristics, surgical details and postoperative outcomes were compared. The primary end-point was CGQL (Cleveland Global Quality of Life) score at 12 months. RESULTS:374 patients (100 ta-IPAA vs 274 abd-IPAA) were included. Mean CGQL scores were comparable between the two groups (0.75 ± 0.11 vs 0.71 ± 0.14; respectively, P = 0.1). Quality of life (7.71 ± 1.17 vs 7.30 ± 1.46; P = 0.04) and energy level (7.16 ± 1.52 vs 6.66 ± 1.68; P = 0.03) were significantly better after ta-IPAA, while the quality of health item was comparable (7.68 ± 1.26 vs 7.64 ± 1.44; P = 0.9655). Stool frequencies (> 10/24 h:22% vs 21%; P = 1.0) and major incontinence rates (27% vs 26%; P = 0.89) were similar. Thirty-day morbidity rates (33% vs 41%; P = 0.2) and anastomotic leak rates were comparable (6% vs 13%; P = 0.09). CONCLUSION: This study, for the first time, provides evidence of comparable long-term functional outcome of ta-IPAA vs abd-IPAA for UC.
Long-term function after transanal vs. transabdominal ileal pouch-anal anastomosis for ulcerative colitis: a multi-centre cohort study
(Oxford University Press, 2019) Chandrasinghe, P.; Carvello, M.; Wasmann, K.; Tanis, P.; Warusavitarne, J.; Spinelli, A.; Bemelman, W.
BACKGROUND:The transanal approach has been introduced in ileal pouch-anal (IPAA) surgery to gain better exposure for the rectal dissection. It has been shown to be safe with lower morbidity than the trans-abdominal approach. The aim of this study was to compare functional outcome of transanal ileal pouch-anal anastomosis (ta-IPAA) with transabdominal (abd-IPAA) approach for ulcerative colitis (UC) using the Cleveland Global Quality of Life (CGQL). METHODS: This is a multi-centre cohort of consecutive patients undergoing abd-IPAA or ta-IPAA for UC prospectively registered in the databases of three tertiary referral institutions between March 2002 to September 2017. Patient characteristics, surgical details and postoperative outcomes were retrieved. The primary end-point was pouch function determined by CGQL score. The questionnaire was administered to all patients with a functioning pouch for 12 months. RESULTS: Ninety-nine patients with ta-IPAA were compared with 274 patients with abd-IPAA. A defunctioning stoma was created at the time of pouch construction in 46 (46%) patients undergoing ta-IPAA and in 130 (47%) patients with abd-IPAA (p = 0.90). Thirty-day postoperative complications according to Clavien-Dindo classification (p = 0.22) as well as anastomotic leak rates (13% vs. 6%), abd-IPAA and ta-IPAA, respectively, were comparable (p = 0.09). Time to stoma closure did not differ between the two groups (abd-IPAA- 6 ± 7 vs. ta-IPAA- 5 ± 4 months; p = 0.72). Twelve months CGQL score was obtained for 251 patients in the abd-IPAA group and for 97 in ta-IPAA cohort. The CGQL index was comparable between the two groups (0.72 ± 0.15 vs. 0.75 ± 0.12; p = 0.07). Quality of health and energy level components were statistically higher for ta-IPAA (7.30 ± 1.53 vs. 7.73 ± 1.19, p = 0.01; 6.68 ± 1.74 vs. 7.17 ± 1.54, p = 0.01) while no difference was found for quality of life item (7.63 ± 1.52 vs. 7.62 ± 1.30, p = 0.73). Pouch failure (including defunction and excision) was reported in 40 of 298 (12%) patients undergoing abd-IPAA and in 1 patient (1%) having ta-IPAA during the follow-up period. CONCLUSIONS: ta-IPAA produces functional result comparable to transabdominal approach at 12 months after surgery.
Transanal ileal pouch-anal anastomosis for ulcerative colitis has comparable long-term functional outcomes to transabdominal approach: a multicentre comparative study

BACKGROUND:The transanal approach to ileal pouch-anal anastomosis (Ta-IPAA) provides better access to the lower pelvis with lower short-term morbidity in ulcerative colitis (UC). The aim of this study was to assess the long-term functional outcomes after Ta-IPAA versus transabdominal IPAA (Abd-IPAA) in UC.STUDY DESIGN:A multicentre cohort analysis was done between March 2002 and September 2017. Patient characteristics, surgical details and postoperative outcomes were compared. CGQL (Cleveland global quality of life) score at 12 months with a functioning pouch was considered the primary endpoint.RESULTS:A total of 374 patients (100 Ta-IPAA vs 274 Abd-IPAA) were included. Ta-IPAA demonstrated a comparable overall quality of life (CGQL score) to Abd-IPAA (0.75 ± 0.11 vs 0.71 ± 0.14; respectively, p=0.1). Quality of life (7.71 ± 1.17 vs 7.30 ± 1.46; p=0.04) and energy level items (7.16 ± 1.52 vs 6.66 ± 1.68; p=0.03) were significantly better after Ta-IPAA, while the quality of health item was comparable (7.68 ± 1.26 vs 7.64 ± 1.44; p=0.96). Analysis excluding anastomotic leaks did not change the overall CGQL scores. Stool frequencies (>10/ 24 hrs:22% vs 21%; p=1.0) and the rate of single episode of major incontinence during the 12-month period (27% vs 26%; p=0.89) were similar. The differences in thirty-day morbidity rates (33% vs 41%; p=0.2) and the anastomotic leak rates were not significant (6% vs 13%; p=0.09). CONCLUSION AND RELEVANCE:This study provides evidence of comparable long-term functional outcome and quality of life after Ta-IPAA and Abd-IPAA for UC.
