Item Single Incision Laparoscopic Surgery (SILS) as surgical option in Crohn's disease: our experience(Wiely-Blackwell, 2016) Leo, C.A.; Samaranayake, S.F.; Hodgkinson, J.D.; Santorelli, C.; Chandrasinghe, P.C.; Warusavitarne, J.AIM :Single Incision Laparoscopic Surgery (SILS) is a newer technique which is increasing in popularity. The benefit of SILS in complex Crohn's disease (CCD), which includes a significant cohort of young patients sometimes needing multiple operations has not been comprehensively assessed. This study analyses our early experience with this technique. METHOD: Patients who underwent SILS for CCD were included. Data were collected prospectively from Januray 2013 to December 2015. Ileocolic resections, right hemicolectomy, small bowel stricturoplasties and resections were included in the CCD cohort. Primary and re-do surgeries were analysed separately. RESULTS: A total of 45 patients were included: 39 ileocolic resections, 6 small bowel stricturoplasty/resections. Of the total, 27 were primary resections and 18 were re-do resections. In overall, the median age was 41 years (Range – 14 years–72 years), the median hospital stay was 8 days (Range - 3 days–28 days). Three patients from primary (11%) and 2 from re-do group (11%) had to be converted to open surgery. Total complication rate was 35.5% including 31.1% Clavien Dindo 1 and 2. In term of operating time, average blood loss, conversion rates, complication rate and hospital stay, there was no significant difference between the groups. Six months follow-up showed no major complications. CONCLUSION:We have demonstrated the feasibility of SILS in patients with CCD undergoing both primary and re-do surgeries. There were no significant differences between the two groups. More robust data and longer follow-up is needed in future studies to evaluate this further.Item Transanal minimally invasive proctectomy (TaMIP) in patients with Crohn’s disease: A cohort study from the TaTME international database(Oxford University Press, 2018) Pellino, G.; Sahnan, K.; Penna, M.; Adegbola, S.; Chandrasinghe, P.; Hompes, R.; Spinelli, A.; Warusavitarne, J.; International TaTME Registry CollaborativeBACKGROUND :Perianal Crohn’s disease (pCD) is a debilitating condition and despite the advances of medical and surgical treatment, a proportion of patients eventually require proctectomy for severe and/or refractory pCD. TaTME has several advantages, particularly in patients with low rectal cancer, narrow pelvis, previous radiation and bulky prostate. Aim of this study is to assess the feasibility of transanal minimally invasive proctectomy (TaMIP) within the International TaTME registry. METHODS:The TaTME registry was interrogated from 2014 to 2017 for benign conditions. Data were collected across 11 international centres submitted for patients who received TaMIP, with or without TME, for pCD. RESULTS:Forty patients (mean age 42.6 ± 13.8 years) underwent TaMIP for pCD with a median total operative time of 202 ± 102 min for the abdominal phase and 126 ± 58 min for the perineal phase. The majority of patients were female (67.5%; 27 of 40), 80.0% had active IBD at the time of surgery and average duration of follow-up was 4.4 ± 5.8 months. The commonest approach to proctectomy was an intersphincteric APE (30.0%; 12 of 40), with over half of cases (52.5%; 21 of 40) undergoing total intersphincteric dissection. The median height of the pursestring was 4.4 ± 2.4 cm and the most common extraction site was transanal (37.5%; 15 of 40). Intact specimens were found in 21% (8 of 38 TME) and major defects in four cases. During the abdominal phase, 29% (9 of 31) cases were converted-to-open procedure (all strategic) and 20% (8 of 40) during the perineal phase. Peri-operative complications during perineal dissection were: bleeding (12.5%, 5 of 40), incorrect plane (15%, 6 of 40), issues with smoke extraction (12.5%; 5 of 40) and maintaining pneumopelvis (10.0%; 4 of 40). Rectal perforations occurred in two cases at a median of 4 ± 2.8 cm from the anal verge. There were no urethral injuries and blood loss was < 100 ml in 45.4% (15.33) in our cohort. The average length of stay was 6 ± 5 days with no post-operative mortalities. The majority of patients (75.0%; 30 of 40) had no complications. Two-thirds of patients had Clavien-Dindo grade II complications (60.0%; 6 of 40) and one patient had a grade III complication. Late morbidity (>1 month) was available for 23 patients and perineal wound complications were identified in over half of patients (56.5%). CONCLUSIONS: pCD causes perineal fibrosis and chronic sepsis, which can make proctectomy an extremely complex operation (particularly when associated with proctitis), thereby increasing the risk of complications. TaMIP offers a safe and feasible minimally invasive approach to this subset of patients. Outcomes from TaMIP need to be compared with current techniques in order to discern the future role and training requirements for this promising new technique.
