Impact of single-incision laparoscopic surgery on postoperative analgesia requirements after total colectomy for ulcerative colitis: a propensity-matched comparison with multiport laparoscopy

AIM: To compare the requirements for postoperative analgesia in patients with ulcerative colitis after single-incision versus multiport laparoscopic total colectomy. METHOD: All patients undergoing single-incision or multiport laparoscopic total colectomy as a first stage in the surgical treatment of ulcerative colitis between 2010 and 2016 at the University Hospital of Leuven were included. The cumulative dose of postoperative patient-controlled analgesia was used as the primary end-point. A Z-transformation was performed combining values for patient-controlled epidural analgesia and patient-controlled intravenous analgesia, resulting in one hybrid outcome variable. The two groups were matched using propensity scores. Subgroup analysis was performed to analyse the impact of extraction site on postoperative pain. RESULTS: A total of 81 patients underwent total colectomy for ulcerative colitis (median age 35 years). Thirty patients underwent single-incision laparoscopy, while 51 patients had a multiport approach. The mean normalized patient-controlled analgesia dose was significantly lower in patients undergoing single-incision laparoscopy (-0.33 vs 0.46, P < 0.001). This difference was no longer significant in subgroup analysis for patients with stoma site specimen extraction (P = 0.131). The odds of receiving tramadol postoperatively was 3.66 times lower after single-incision laparoscopy (P = 0.008). The overall morbidity rate was 32.1% (26/81). The mean Comprehensive Complication Index in single-incision and multiport laparoscopy group was 18.33 and 21.39, respectively (P = 0.506). Hospital stay was significantly shorter after single-incision laparoscopic surgery (6.3 days vs 7.6 days, P = 0.032). CONCLUSION: Single-incision total colectomy was associated with lower postoperative analgesia requirements and shorter hospital stay, with comparable morbidity. However, the specimen extraction site played a significant role in postoperative pain control.status: publishe

How do patients score cosmesis after laparoscopic natural orifice specimen extraction colectomy?

Laparoscopic colorectal resection results in improved cosmetic outcome and better presumed body image. Laparoscopic NOSE-colectomy omits an incision for specimen extraction and is supposed to improve further the postoperative cosmesis. This study aimed to assess the cosmetic benefit.status: publishe

Single port laparoscopic ileocaecal resection for Crohn's disease: a multicentre comparison with multi-port laparoscopy

AimSingle port (SP) ileocaecal resection (ICR) is an established technique but there are no large studies comparing SP and multi-port (MP) laparoscopic surgery in Crohn's disease (CD). The aim of this study was to compare postoperative pain scores and analgesia requirements after SP and MP laparoscopic ICR for CD. MethodThis was a retrospective study of patients undergoing SP or MP ICR for CD in three tertiary referral centres from February 1999 to October 2014. Baseline characteristics (age, sex, body mass index and indication for surgery) were compared. Primary end-points were postoperative pain scores, analgesia requirements and short-term postoperative outcomes. ResultsSP ICR (n=101) and MP ICR (n=156) patients were included in the study. Visual analogue scale scores were significantly lower after SP ICR on postoperative day 1 (P=0.016) and day 2 (P=0.04). Analgesia requirements were significantly reduced on postoperative day 2 in the SP group compared with the MP group (P=0.007). Duration of surgery, conversion to open surgery and stoma rates were comparable between the two groups. Surgery was more complex in terms of additional procedures when MP was adopted (P=0.001). There were no differences in postoperative complication rates, postoperative food intake, length of stay and readmissions. ConclusionThese data suggest that in comparison to standard laparoscopic surgery SP ICR might be less painful and patients might require less opioid analgesi

Defunctioning Ileostomy is not Associated with Reduced Leakage in Proctocolectomy and Ileal Pouch Anastomosis Surgeries for IBD

Anastomotic leakage is a serious complication after restorative proctocolectomy with ileal pouch-anal anastomosis. Previous studies have shown significantly decreased leak rates in diverted patients with less severe clinical consequences. The aim of this study was to evaluate short- and long-term outcome of selective ileostomy formation in a multicentre cohort of patients undergoing pouch surgery. In a retrospective study, 621 patients undergoing pouch surgery for inflammatory bowel disease [IBD] were identified from three large centres. Anastomotic leakage was defined as any leak confirmed by either contrast extravasation on imaging or during surgical re-intervention. In 305 patients [49.1%], primary defunctioning ileostomy was created during pouch surgery and 41 [6.6%] patients received a secondary ileostomy because of a leaking non-diverted pouch. Primary ileostomy formation was associated with male sex, weight loss, American Society of Anesthesiologists score [ASA] > 2, steroid use, one-stage surgery, hand-sewn anastomosis, and blood transfusion. Leak rates were comparable between diverted and non-diverted patients [16.7% vs 17.1%, p = 0.92], which remained unchanged in subgroups with immunosuppressive medication. Having had an ileostomy was demonstrated to be an independent predictor of small bowel obstruction (odds ratio [OR] 2.58, 95% confidence interval [CI] 1.45 - 4.67) and pouch fistulas [OR 3.05, 95%CI 1.06 - 8.73]. The 10-year pouch survival was comparable for patients with and without ileostomy [89% versus 88%, p = 0.718]. Leakage rates of diverted and non-diverted pouches in IBD patients were similar and relatively high. Defunctioning was independently associated with long-term complications. A staged approach without defunctioning might be the best strateg

External validation of a prognostic model of preoperative risk factors for failure of restorative proctocolectomy

Aim The Cleveland Clinic has proposed a prognostic model of preoperative risk factors for failure of restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis. The model incorporates four predictive variables: completion proctectomy, handsewn anastomosis, diabetes mellitus and Crohn's disease. The aim of the present study was to perform an external validation of this model in a new cohort of patients who had RPC. Method Validation was performed in a multicentre cohort of 747 consecutive patients who had an RPC between 1990 and 2015 in three tertiary-care facilities, using a Kaplan-Meier survival analysis and Cox regression analysis. The performance of the model was expressed using the Harrell concordance error rate. The primary outcome measure was pouch survival with maintenance of anal function. Results During the study period, 45 (6.0%) patients experienced failure at a median interval of 31 months (interquartile range 9-82 months) from the original RPC. Multivariable analysis showed handsewn anastomosis to be the only significant independent predictor. The Harrell concordance error rate was 0.42, indicating poor performance. Anastomotic leakage and Crohn's disease of the pouch were strong postoperative predictors for pouch failure and showed a significant difference in pouch survival after 10 years (P <0.001). Conclusion The poor performance of the Cleveland Clinic prognostic model makes it unsuitable for daily clinical practice. Handsewn anastomosis was associated with pouch failure in our cohort with relatively few events. A prediction model for anastomotic leakage or Crohn's disease of the pouch may be a better solution since these variables are strongly associated with pouch failur

Risk Factors for Small Bowel Obstruction After Laparoscopic Ileal Pouch-Anal Anastomosis for Inflammatory Bowel Disease: A Multivariate Analysis in Four Expert Centres in Europe

BACKGROUND AND AIMS: Although laparoscopy is associated with a reduction in adhesions, no data are available about the risk factors for small bowel obstruction [SBO] after laparoscopic ileal pouch-anal anastomosis [IPAA]. Our aims here were to identify the risk factors for SBO after laparoscopic IPAA for inflammatory bowel disease [IBD]. METHODS: All consecutive patients undergoing laparoscopic IPAA for IBD in four European expert centres were included and divided into Groups A [SBO during follow-up] and B [no SBO]. RESULTS: From 2005 to 2015, SBO occurred in 41/521 patients [Group A; 8%]. Two-stage IPAA was more frequently complicated by SBO than 3- and modified 2-stage IPAA [12% vs 7% and 4%, p = 0.04]. After multivariate analysis, postoperative morbidity (odds ratio [OR] = 3, 95% confidence interval [CI] = 1.5-7, p = 0.002), stoma-related complications [OR = 3, 95% CI = 1-6, p = 0.03] and long-term incisional hernia [OR = 6, 95% CI = 2-18, p = 0.003] were predictive factors for SBO, while subtotal colectomy as first surgery was an independent protective factor [OR = 0.4, 95% CI = 0.2-0.8, p = 0.002]. In the subgroup of patients receiving restorative proctocolectomy as first operation, stoma-related or other surgical complications and long-term incisional hernia were predictive of SBO. In the patient subgroup of subtotal colectomy as first operation, postoperative morbidity and long-term incisional hernia were predictive of SBO, whereas ulcerative colitis and a laparoscopic approach during the second surgical stage were protective factors. CONCLUSIONS: We found that SBO occurred in less than 10% of patients after laparoscopic IPAA. The study also suggested that modified 2-stage IPAA could potentially be safer than procedures with temporary ileostomy [2- and 3-stage IPAA] in terms of SBO occurrence.status: publishe
