Lower endoscopy (LE) is the standard diagnostic modality for lower gastrointestinal bleeding (LGIB). Conversely, computed tomographic angiography (CTA) offers an immediate non-invasive diagnosis visualizing the entire gastrointestinal tract. The aim of this study was to compare these 2 modalities with regards to diagnostic value and bleeding control. Tertiary center retrospective analysis of consecutive patients admitted for LGIB between 2006 and 2012. Comparison of patients with LE vs. CTA as first exam, respectively, with emphasis on diagnostic accuracy and bleeding control. Final analysis included 183 patients; 122 (66.7%) had LE first, while 32 (17.5%) had CTA; 29 (15.8%) had neither of both exams. Median time to CTA was shorter compared to LE (3 (IQR = 8.2) vs. 22 (IQR = 36.9) hours, P < 0.001). Active bleeding was identified in 31% with CTA vs. 15% with LE (P = 0.031); a non-actively bleeding source was found by CTA and LE in 22 vs. 31%, respectively (P = 0.305). Bleeding control required endoscopy in 19%, surgery in 14% and embolization in 1.6%, while 66% were treated conservatively. Post-interventional bleeding was mostly controlled by endoscopic therapy (57%). 80% of patients with active bleeding on CTA required surgery. Post-interventional LGIB was effectively addressed by LE. For other causes of LGIB, CTA was efficient, and more available than colonoscopy. Treatment was conservative for most patients. In case of active bleeding, CTA could localize the bleeding source and predict the need for surgery.

Surgical site infection after stoma reversal is common. The optimal skin closure technique after stoma reversal has been widely debated in the literature. We hypothesized that pursestring near-complete closure of the stoma site would lead to fewer surgical site infections compared with conventional primary closure. This study was a parallel prospective multicenter randomized controlled trial. This study was conducted at 2 university medical centers. Patients (N = 122) presenting for elective colostomy or ileostomy reversal were selected. Pursestring versus conventional primary closure of stoma sites were compared. Stoma site surgical site infection within 30 days of surgery, overall surgical site infection, delayed healing (open wound for >30 days), time to wound epithelialization, and patient satisfaction were the primary outcomes measured. The pursestring group had a significantly lower stoma site infection rate (2% vs 15%, p = 0.01). There was no difference in delayed healing or patient satisfaction between groups. Time to epithelialization was measured in only 51 patients but was significantly longer in the pursestring group (34.6 ± 20 days vs 24.1 ± 17 days, p = 0.02). This study was limited by the variability in procedures and surgeons, the limited follow-up after 30 days, and the inability to perform blinding. Pursestring closure after stoma reversal has a lower risk of stoma site surgical site infection than conventional primary closure, although wounds may take longer to heal with the use of this approach.

Background: Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non-steroidal anti-inflammatory drugs (NSAIDs) for reducing ileus after surgery. Methods: A prospective multicentre cohort study was delivered by an international, student- and trainee-led collaborative group. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The primary outcome was time to gastrointestinal recovery, measured using a composite measure of bowel function and tolerance to oral intake. The impact of NSAIDs was explored using Cox regression analyses, including the results of a centre-specific survey of compliance to enhanced recovery principles. Secondary safety outcomes included anastomotic leak rate and acute kidney injury. Results: A total of 4164 patients were included, with a median age of 68 (i.q.r. 57–75) years (54·9 per cent men). Some 1153 (27·7 per cent) received NSAIDs on postoperative days 1–3, of whom 1061 (92·0 per cent) received non-selective cyclo-oxygenase inhibitors. After adjustment for baseline differences, the mean time to gastrointestinal recovery did not differ significantly between patients who received NSAIDs and those who did not (4·6 versus 4·8 days; hazard ratio 1·04, 95 per cent c.i. 0·96 to 1·12; P = 0·360). There were no significant differences in anastomotic leak rate (5·4 versus 4·6 per cent; P = 0·349) or acute kidney injury (14·3 versus 13·8 per cent; P = 0·666) between the groups. Significantly fewer patients receiving NSAIDs required strong opioid analgesia (35·3 versus 56·7 per cent; P < 0·001). Conclusion: NSAIDs did not reduce the time for gastrointestinal recovery after colorectal surgery, but they were safe and associated with reduced postoperative opioid requirement.

Introduction: According to the Barcelona Clinic Liver Cancer (BCLC) algorithm, transarterial chemoembolization (TACE) is recommended in patients with hepatocellular carcinoma (HCC) of intermediate stage (BCLC-B), whereas partial hepatectomy (PH) is restricted to early stage A. Expanding the indication for PH to intermediate stage remains debated. Objective: This meta-analysis aimed to analyze short- and long-term outcomes of PH compared to TACE in patients with intermediate-stage HCC. Methods: A meta-analysis was conducted according to PRISMA guidelines. Trials comparing PH with TACE in patients with intermediate-stage HCC were selected. Only patients of BCLC-B stage were included in the analyses. Primary endpoint was overall survival (OS) and secondary endpoint was 90-day postprocedural mortality. Random-effects models were used to analyze time ratios (TRs). Results: Seven eligible trials were analyzed, including 1,730 BCLC-B patients undergoing PH (n = 750) or TACE (n = 980). Comparison of OS between PH and TACE determined a pooled TR of 1.91 (95% CI 1.24–2.94; p < 0.001). Survival rates at 1-, 3-, and 5-year were 85, 60, and 42% after PH, compared to 73, 60, and 20% after TACE (p < 0.001). There was no difference in postprocedural mortality between PH and TACE with rates of 3.7 and 3.4%, respectively (TR 0.95; 95% CI 0.17–5.50; p = 0.879). Conclusions: In patients with intermediate HCC, PH was associated with increased long-term survival compared to TACE, with comparable postprocedural mortality. These results suggest considering PH as treatment option in intermediate HCC and highlight the urgent need to refine the selection of patients with BCLC-B stage who may benefit from PH.

Background: Anxiety is common before surgery and known to negatively impact recovery from surgery. The aim of this study was to evaluate the impact of a preoperative nurse dialogue on a patient’s anxiety, satisfaction and early postoperative outcomes. Method: This 1:1 randomized controlled trial compared patients undergoing major visceral surgery after a semistructured preoperative nurse dialogue (interventional group: IG) to a control group (CG) without nursing intervention prior to surgery. Anxiety was measured with the autoevaluation scale State-Trait Anxiety Inventory (STAI, Y-form) pre and postoperatively. The European Organization for Research and Treatment of Cancer (EORTC) In-Patsat32 questionnaire was used to assess patient satisfaction at discharge. Further outcomes included postoperative pain (visual analogue scale: VAS 0–10), postoperative nausea and vomiting (PONV), opiate consumption and length of stay (LOS). Results: Over a period of 6 months, 35 participants were randomized to either group with no drop-out or loss to follow-up (total n = 70). The median score of preoperative anxiety was 40 (IQR 33–55) in the IG vs. 61 (IQR 52–68) in the CG (p < 0.001). Postoperative anxiety levels were comparable 34 (IQR 25–46) vs. 32 (IQR 25–44) for IG and CG, respectively (p = 0.579). The IG did not present higher overall satisfaction (90 ± 15 vs. 82.9 ± 16, p = 0.057), and pain at Day 2 was similar (1.3 ± 1.7 vs. 2 ± 1.9, p = 0.077), while opiate consumption, PONV levels and LOS were comparable. Conclusion: A preoperative dialogue with a patient-centered approach helped to reduce preoperative anxiety in patients undergoing major visceral surgery.

Objectives: To assess the interobserver reliability (IOR) of the Tile classification system, and its potential influence on outcomes, for the interpretation of CT images of pelvic fractures by radiologists and surgeons.Methods: Retrospective data (1/2008–12/2016) from 238 patients with pelvic fractures were analyzed. Mean patient age was 44 years (SD 20); 66% were male. There were 54 Tile A, 82 Tile B, and 102 Tile C type injuries. The 30-day mortality rate was 15% (36/238). Six observers, three radiologists, and three surgeons with different levels of experience (attending/resident/intern) classified each fracture into one of the 26 second-order subcategories of the Tile classification. Weighted kappa coefficients were used to assess the IORs for the three main categories and nine first-order subcategories.Results: The overall IORs of the Tile system for the main categories and first-order subcategories were moderate (kappa = 0.44) and fair (kappa = 0.31), respectively. IOR was fair to moderate among radiologists, but only fair among surgeons. By level of training, IOR was moderate between attendings and between residents, whereas it was only fair between interns. IOR was moderate to substantial (kappa = 0.56–0.70) between the radiology attending and resident. Association of the Tile fracture type with 30-day mortality was present based on two out of six observer ratings.Conclusions: The overall IOR of the Tile classification system is only fair to moderate, increases with the level of rater experience and is better among radiologists than surgeons. In the light of these findings, results from studies using this classification system must be interpreted cautiously.Key Points: •The overall interobserver reliability of the Tile pelvic fracture classification is only fair to moderate.•Interobserver reliability increases with observer experience and radiologists have higher kappa coefficients than surgeons.•Interobserver reliability has an impact on the association of the Tile classification system with mortality in two out of six cases.
