Enhanced Recovery After Surgery (ERAS^®) is a multimodal perioperative framework designed to mitigate the physiological stress response to major surgery. While ERAS protocols consistently reduce length of hospital stay, overall complication rates, and healthcare costs compared to conventional care, their specific impact on surgical site infections (SSIs) remains poorly defined. This review explores the potential synergistic benefits of integrating ERAS protocols with established infection prevention bundles. By evaluating the current clinical evidence, we analyze how the co-implementation of these two evidence-based strategies can collectively reduce the incidence of SSIs.

Various papers have introduced the use of positron emission tomography (PET) with [⁶⁸Ga]Ga-radiolabeled fibroblast-activation protein inhibitor (FAPi) radiopharmaceuticals in different subtypes of gastric cancer (GC). Our aim was to assess the diagnostic performance of this novel molecular imaging technique in GC with a systematic review and meta-analysis. A straightforward literature search of papers concerning the diagnostic performance of FAP-targeted PET imaging was performed. Original articles evaluating this novel molecular imaging examination in both newly diagnosed GC patients and GC patients with disease relapse were included. The systematic review included nine original studies, and eight of them were also eligible for meta-analysis. The quantitative synthesis provided pooled detection rates of 95% and 97% for the assessment of primary tumor and distant metastases, respectively, and a pooled sensitivity and specificity of 74% and 89%, respectively, for regional lymph node metastases. Significant statistical heterogeneity among the included studies was found only in the analysis of the primary tumor detection rate (I² = 64%). Conclusions: Beyond the limitations of this systematic review and meta-analysis (i.e., all the included studies were conducted in Asia, and using [¹⁸F]FDG PET/CT as a comparator of the index test), the quantitative data provided demonstrate the promising diagnostic performance of FAP-targeted PET imaging in GC. Nevertheless, more prospective multicentric studies are needed to confirm the excellent performances of FAP-targeted PET in this cluster of patients.

Esophagectomy is the selected treatment for nonmetastatic esophageal and esophagogastric junction cancer, although high perioperative morbidity and mortality incur. Robot-assisted minimally invasive esophagectomy (RAMIE) effectively reduces cardiopulmonary complications compared to open esophagectomy and offers a technical advantage, especially for lymph node dissection and intrathoracic anastomosis. This article aims at describing our initial experience of Ivor Lewis RAMIE, focusing on the technique’s main steps and robotic-sewn esophagogastrostomy. Prospectively collected data from all consecutive patients who underwent Ivor Lewis RAMIE for cancer was reviewed. Reconstruction was performed with a gastric conduit pull-up and a robotic-sewn intrathoracic anastomosis. Intraoperative and postoperative complications were recorded as prescribed by the Esophagectomy Complications Consensus Group (ECCG). Thirty patients underwent Ivor Lewis RAMIE with complete mediastinal lymph node dissection and robot-sewn anastomosis. No intraoperative complications nor conversion occurred. Pulmonary complications totaled 26.7%. Anastomotic leakage (ECCG, type III) and conduit necrosis (ECCG, type III) both occurred in one patient (3.3%). Chylothorax appeared in 2 patients (6.7%) (ECCG, Type IIA). Anastomotic stricture, successfully treated with endoscopic dilatations, occurred in 8 cases (26.7%). Median overall postoperative stay was 11 days (range, 6–51 days). 30 day and 90 day mortality was 0%. R0 resection was performed in 96.7% of patients with a median number of 47 retrieved lymph nodes. RAMIE with robot-sewn intrathoracic anastomosis appears to be feasible, safe and effective, with favorable perioperative results. Nevertheless, further high-quality studies are needed to define the best anastomotic technique for Ivor Lewis RAMIE.

Early postoperative low compliance to enhanced recovery protocols has been associated with morbidity following colon surgery. The purpose of this study is to evaluate the possible causes of early postoperative low compliance to the enhanced recovery pathway and its relationship with morbidity following rectal surgery for cancer. A total of 439 consecutive patients who underwent elective surgery for rectal cancer have been included in the study. Compliance to enhanced recovery protocol on postoperative day (POD) 2 was evaluated in all patients. Indicators of compliance were naso-gastric tube and urinary catheter removal, recovery of both oral feeding and mobilization, and the stopping of intravenous fluids. Low compliance on POD 2 was defined as non- adherence to two or more items. One-third of patients had low compliance on POD 2. Removal of urinary catheter, intravenous fluids stop, and mobilization were the items with lowest adherence. Advanced age, duration of surgery, open surgery and diverting stoma were predictive factors of low compliance at multivariate analysis. Overall morbidity and major complications were significantly higher (p < 0.001) in patients with low compliance on POD 2. At multivariate analysis, failure to remove urinary catheter on POD 2 (OR = 1.83) was significantly correlated with postoperative complications. Low compliance to enhanced recovery protocol on POD 2 was significantly associated with morbidity. Failure to remove the urinary catheter was the most predictive indicator. Advanced age, long procedure, open surgery and diverting stoma were independent predictive factors of low compliance.

Background: In 2019, the Enhanced Recovery After Surgery (ERAS) protocol for colorectal cancer surgery was adopted by a minority of hospitals in Piemonte (4.3 million inhabitants, north-west Italy). The present analysis aims to compare the level of application of the ERAS protocol between hospitals already adopting it (ERAS, N = 3) with the rest of the regional hospitals (non-ERAS, N = 28) and to identify possible obstacles to its application. Methods: All patients surgically treated for a newly diagnosed colorectal cancer during September–November 2019, representing the baseline period of a randomized controlled trial with a cluster stepped-wedge design, were included. Indicators of compliance to the ERAS items were calculated overall and for groups of items (preoperative, intraoperative and postoperative) and analyzed with a multilevel linear model adjusting for patients’ characteristics, considering centers as random effects. Results: Overall, the average level of compliance to the ERAS protocol was 56% among non-ERAS centers (N = 364 patients) and 80% among ERAS ones (N = 79), with a difference of 24% (95% CI: −41.4; −7.3, p = 0.0053). For both groups of centers, the lowest level of compliance was recorded for postoperative items (42% and 66%). Sex, age, presence of comorbidities and American Society of Anesthesiologists (ASA) score were not associated with a different probability of compliance to the ERAS protocol. Conclusions: Several items of the ERAS protocol were poorly adopted in colorectal surgery units in the Piemonte region in the baseline period of the ERAS Colon-Rectum Piemonte study and in the ERAS group. No relevant obstacles to the ERAS protocol implementation were identified at patient level.

The purpose of this study is to compare the early postoperative and pathological outcomes of robotic right colectomy (RRC) to those of laparoscopic right colectomy (LRC) with intracorporeal anastomosis (IA) within the systematic application of an enhanced recovery after surgery (ERAS) program. A single-institution prospective database of patients who underwent elective RRC or LRC with IA for neoplastic lesions between April 2010 and June 2018 was retrospectively reviewed. The patients’ demographic characteristics, and perioperative and pathological outcomes were analyzed. Propensity-weighted analysis was employed to address potential selection biases of treatment allocation. A total of 216 patients (46 RRC, 170 LRC) were included. RRC demonstrated a significantly longer operative time (mean 242.43 min, SD 47.51) compared to LRC (mean 187.60 min, SD 56.60) (p = 0.001), confirmed by the propensity-weighted analysis (Coefficient 50.65; p < 0.001). Conversion rate between the two groups was comparable (p = 0.99). Median length of hospital stay (LOS) was the same in the RRC and the LRC group (4 days, p = 0.35). Readmission rate within 30 days in the RRC and LRC group was 2.2% and 2.4%, respectively (p = 0.99). Overall 30-day morbidity and 30-day mortality was 32.6% versus 27.1% (p = 0.46), and 0% versus 1.2% (p = 0.99) in the robotic and laparoscopic groups, respectively. No difference was found in the number of harvested lymph nodes (p = 0.75). In an ERAS environment, without the bias of mixed techniques of anastomosis, RRC had similar postoperative and pathological outcomes compared to the laparoscopic approach, but was associated with a longer operative time.
