BACKGROUND : The necessity of proctectomy in IBD often represents refractory disease, with severe active/chronic inflammation, frequently in the context of immunosuppression. Minimally invasive techniques are currently being used as an option in the often challenging operations required. We aim to assess the feasibility and short-term outcomes of a transanal minimally invasive approach to proctectomy (TaMIP) in patients undergoing surgery for IBD within the TaTME registry. METHODS: The TaTME registry (secure online database), was interrogated from 2014 to 2017 for benign conditions. Data were collected across 11 international centres submitted for IBD patients. Patients with ulcerative colitis (UC) received proctectomy with or without Ta-IPAA, and patients with Crohn’s disease (CD) received TaMIP, with or without total mesorectal excision (TME), for perianal CD (pCD).RESULTS: In total, 174 patients with a median BMI of 25.6 ± 4.7 kg/m2 were entered into the database. The majority of patients (77%; 134 of 174) had UC and 79.9% (111 of 174) had a simultaneous laparoscopic or single-incision laparoscopic (SILS) approach to the abdomen. Active IBD featured in 63.8% (111 of 174) which was more prominent in the CD patients (80% vs. 59%, p = 0.015) and 19% (33 of 174) were on steroids at the time of surgery. The median total operative time was 249 ± 113 min (abdominal phase 206 ± 112 and perineal phase 133 ± 60 min). An incorrect plane was the most common problem encountered intra-operatively (10.3%; 18 of 174) followed by bleeding (9.2%; 16 of 174). There was an inadvertent rectal perforation rate of 5.6% (6 of 107). Over a fifth of abdominal procedures were converted (21.6%; 30 of 139) compared with 17 (9.8%) in the perineal phase. There were more perineal conversions in CD patients (20% vs. 6.7%, p = 0.028). A purse-string was used in 51.1% (81 of 174) at a median height of 3.8 ± 2 cm. Most anastomoses were created using a stapler (85.1%; 57 of 67) at median distance of 2.9 ± 1.5 cm from the anal verge. The median length of postoperative stay was 9 ± 6.5 days, which was longer in the UC patients (9 ± 7 days vs. 6 ± 5 days, p = 0.0079). There were no mortalities. Forty-four patients (25.3%) had a complication and seven (15.9%) of these (i.e. 4% of total cohort) had a grade III Clavien-Dindo complication (re-operation). Data on late morbidity (>1 month) were available in 92 patients and 15 of these patients (16.3%) had a wound breakdown. Two of these had a VAC dressing and three had re-operations. There was a trend towards more wound sinuses in CD (19% vs. 4.8%, p = 0.062). CONCLUSIONS:Our results demonstrate that the application of a transanal minimally invasive approach to proctectomy is a feasible option in IBD patients with a relatively low complication rate.
Incidence, prevalence and trends in IBD
(CRC Press, 2018) Chandrasinghe, P.; Spinelli, A.; Warusavitarne, J.
The inflammatory bowel diseases (IBD), Crohn’s disease and ulcerative colitis, are inflammatory conditions of unknown aetiology that affect the gastrointestinal tract. In Saudi Arabia, an increasing incidence of IBD has been registered, and a comparable disease progression has been recognised. Disease location is a significant factor associated with the long-term outcome in IBD. Extra-intestinal manifestations are pathologically and clinically important entities in IBD. Mortality due to IBD may be caused by complications of acute flares of the disease, long-term complication of the disease or surgical complications. Surgery is required in patients with IBD mainly for intestinal complications. The natural history of IBD is difficult to assess in today’s context, as a majority patients with symptoms will be undergoing some form of treatment. The downward trend may have been the result of more comprehensive surveillance programmes established in many high-volume IBD centres. IBDs are common chronic conditions, which place a significant burden on the individual and community.
Technical variations and feasibility of transanal ileal pouch-anal anastomosis for ulcerative colitis and inflammatory bowel disease unclassified across continents.
(Springer-Verlag, 2018) Zaghiyan, K.; Warusavitarne, J.; Spinelli, A.; Chandrasinghe, P.; Di Candido, F.; Fleshner, P.
PURPOSE: Initial reports of transanal ileal pouch-anal anastomosis (taIPAA) suggest safety and feasibility compared with transabdominal IPAA. The purpose of this study was to evaluate differences in technique and results of taIPAA in three centers performing taIPAA across two continents. METHODS: Prospective IPAA registries from three institutions in the US and Europe were queried for patients undergoing taIPAA. Demographic, preoperative, intraoperative, and postoperative data were compiled into a single database and evaluated. RESULTS: Sixty-two patients (median age 38 years; range 16-68 years, 43 (69%) male) underwent taIPAA in the three centers (USA 24, UK 23, Italy 15). Most patients had had a subtotal colectomy before taIPAA [n = 55 (89%)]. Median surgical time was 266 min (range 180-576 min) and blood loss 100 ml (range 10-500 ml). Technical variations across the three institutions included proctectomy plane of dissection (intramesorectal or total mesorectal excision plane), specimen extraction site (future ileostomy site vs. anus), ileo-anal anastomosis technique (stapled vs. hand sewn) and use of fluorescence angiography. Despite technical differences, anastomotic leak rates (5/62; 8%) and overall complications (18/62; 29%) were acceptable across the three centers. CONCLUSIONS: This is the first collaborative report showing safety and feasibility of taIPAA. Despite technical variations, outcomes are similar across centers. A large multi-institutional, international IPAA collaborative is needed to compare technical factors and outcomes.
