PIPAC is feasible, safe and well tolerated. Preliminary good response rates call for prospective analysis of oncological efficacy.

Background: Mobilization after surgery is recommended to reduce the risk of adverse effects and to improve recovery. The aim of this study was to examine the associations between perioperative physical activity and postoperative outcomes in colorectal surgery. Methods: The daily number of footsteps was recorded from preoperative day 5 to postoperative day 3 in a prospective cohort of patients using wrist accelerometers. Timed Up and Go Test (TUGT), 6 Min Walking Test (6MWT), and peak expiratory flow (PEF) were assessed preoperatively. ROC curves were used to assess the performance of physical activity as a diagnostic test of complications and prolonged length of stay (LOS) of more than 5 days. Results: A total of 50 patients were included. Patients with complications were significantly older (67 years) than those without complications (53 years, p = 0.020). PEF was significantly lower in the group with complications (mean flow 294.3 vs. 363.6 L/min, p = 0.038) while there was no difference between groups for the other two tests (TUGT and 6MWT). The tests had no capacity to discriminate the occurrence of complications and prolonged LOS, except the 6MWT for LOS (AUC = 0.746, p = 0.004, 95% CI: 0.604-0.889). There was no difference in the mean number of preoperative footsteps, but patients with complications walked significantly less postoperatively (mean daily footsteps 1,101 vs. 1,243, p = 0.018). Conclusions: Colorectal surgery patients with complications were elderly, had decreased PEF, and walked less postoperatively. The 6MWT could be used preoperatively to discriminate patients with potentially increased LOS and foster mobilisation strategies.

Background Outpatient appendectomy for acute appendicitis is a feasible, yet not widely performed procedure, as there are no universally accepted criteria for patient selection. The aim of this study was to assess preoperative clinical factors associated with successful short-stay appendectomy (SSA) and establish a predictive score to help with patient selection. Methods All consecutive laparoscopic appendectomies performed in our institution between January 2013 and June 2015 were retrospectively analyzed. Several preoperative clinical and biological variables were compared between patients with SSA, defined as a postoperative stay \24 h, and those needing inpatient care. Logistic regression analysis was used to identify variables independently associated with SSA, and these variables were then used to create a predictive score. Results A total of 578 patients were included, 303 (53%) in the SSA group and 275 (48%) in the long-stay appendectomy (LSA) group. In multivariate analysis, male gender (OR 1.61, 95% CI 1.12-2.31, p = 0.010), ASA class I-II (OR 9.52, 95% CI 1.65-180.69, p = 0.037), absence of generalized guarding (OR 3.55, 95% CI 1.30-11.41, p = 0.019), C-reactive protein \100 mg/dl (OR 3.09, 95% CI 1.81-5.42, p \ 0.001) and leukocyte count \20 g/l (OR 2.06, 95% CI 1.02-4.30, p = 0.046) were independently associated with SSA. These five parameters were used to construct a predictive score, whereby C17 (range 0-21) was defined as the optimal threshold to predict SSA with a high sensitivity (95.6%) and negative predictive value (82.2%). Conclusions A purely clinical predictive score based on five widely used preoperative parameters can be used to identify eligible patients for short-stay appendectomy.
