Introduction: This study aimed to evaluate the influence of early oral feeding (EOF), a key component of enhanced recovery after surgery protocols, on postoperative outcomes in patients undergoing elective colorectal surgery.

Methods: We searched the MEDLINE, Embase, Cochrane Library, and KoreaMed databases to include randomized clinical trials comparing EOF that started on postoperative day 1 and conventional oral feeding that commenced after first flatus. Two authors independently screened the retrieved records and extracted data. The primary outcome was total complications. Data were pooled, and the overall effect size was calculated using a fixed-effect model.

Results: We screened 13 studies, and 1,556 patients were included in the analysis. The EOF group exhibited fewer total complications (odds ratio [OR] 0.50; 95% confidence interval [CI] 0.38-0.65). Anastomotic leakage was also reduced in the EOF group (OR: 0.40; 95% CI: 0.19-0.83); however, an increased incidence of vomiting (OR: 1.58; 95% CI: 1.11-2.26) as well as a tendency of higher rate of nasogastric tube reinsertion (OR: 1.49; 95% CI: 0.96-2.31) were observed. The EOF group demonstrated a decreased time to flatus (mean difference [MD] -0.87; 95% CI: -1.00 to -0.74) and shortened hospital stay (MD: -0.76; 95% CI: -0.89 to -0.6). No significant difference in mortality was observed between the two groups (OR: 0.54; 95% CI: 0.15-2.01).

Conclusion: EOF proved to be a safe and effective practice for patients undergoing elective colorectal surgery. However, the increased incidence of vomiting necessitates careful consideration.

Introduction: The effect of appendectomy on the development of Crohn's disease (CD) is a matter of debate. The aim of this systematic review and meta-analysis was to gather the latest published data to determine whether patients with a history of appendectomy have an increased risk of developing CD or not.

Methods: MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched for case-control and cohort studies assessing the risk of developing CD after appendectomy. The pooled adjusted and not adjusted odds ratio (OR) with 95% confidence intervals (CIs) were calculated for case-control studies. Heterogeneity was assessed. Studies were ranked using the Newcastle-Ottawa Scale (NOS) and were all of good quality.

Results: Fourteen case-control studies and 6 cohort studies were included. Meta-analysis of case-control studies (33,243 patients) of raw OR shows a positive association between appendectomy and CD (OR: 1.51, 95% CI: 0.97-2.36, I2 = 87%), which was not statistically significant (p = 0.069). The meta-analysis of adjusted OR shows that appendectomy represents a statistically significant risk factor for the development of CD (OR: 1.86, 95% CI: 1.01-3.45, p = 0.047, I2 = 89%).

Conclusion: Appendectomy appears to be a risk factor for the development of CD. However, the discrepant results obtained by meta-analysis of unadjusted OR, the heterogeneity between studies, and the lack of precision of the magnitude of the association mandate confirmation by a large epidemiological study.

Introduction: Telementoring could increase the quality, reduce the time, and increase cost efficiency of the proctoring program for robot-assisted minimally invasive esophagectomy (RAMIE). However, feasibility is unclear as no studies assessed telementoring for RAMIE.

Methods: The feasibility of telementoring was assessed during the thoracic part of RAMIE procedures in three high-volume centers. RAMIEs were performed by trained surgeons, proctored by two experts. The primary outcome was the impact of the technology on conveying and understanding instructions.

Results: Between December 2021 and December 2022, nine RAMIE procedures were proctored using telementoring. Overall quality of the telementoring technique was scored good to excellent (median score: good). The vast majority of the 24 proctor instructions were conveyed and understood fluently (n = 21, 96%). Most proctor instructions were aimed at improving surgical exposure (n = 9, 38%). The major point of criticism was the use of the audio as the communication through the headset of the performing surgeon was not accessible by the complete team.

Discussion: Telementoring is deemed feasible for proctoring trained RAMIE surgeons after onsite proctoring. Technical improvements with regard to audio technology are warranted for broad implementation, especially in earlier training settings. The role of telementoring in the training pathway of learning surgeons needs clinical validation.

Introduction: The present study aimed to determine the clinical value of serum procalcitonin (PCT) level in predicting postoperative infections after hepatectomy.

Methods: Medical records of 301 consecutive patients who underwent hepatectomy were retrospectively reviewed. We divided the patients into infection-positive and infection-negative groups. We investigated the changes in perioperative inflammatory markers such as C-reactive protein level (CRP) and PCT level. Associations between infectious complications and perioperative inflammatory markers were evaluated to identify predictive factors of infectious complications after hepatectomy.

Results: Postoperative infectious complications occurred in 67 (22.3%) patients. The areas under the curve (AUCs) using PCT levels on postoperative days (PODs) 1 and 3 were 0.794 and 0.845, respectively, whereas those using CRP were 0.493 and 0.641, respectively. PCT level had a better AUC than CRP for predicting postoperative infectious complications on PODs 1 and 3. Multivariate analysis indicated PCT levels on PODs 1 and 3 were an independent predictor of infectious complications after hepatectomy.

Conclusion: PCT is the only predictive marker for infectious complications after hepatectomy and is valuable for detecting infectious complications from POD 1.

Introduction: There is a lack of sufficient evidence-based data to support personalized treatment decisions for Zenker's diverticulum. This study evaluates not only short-term outcomes of different treatment approaches but also identifies prognostic factors for long-term recurrence-free survival and quality of life.

Methods: We retrospectively analyzed all patients diagnosed with Zenker's diverticulum at our center between 2001 and 2021. Long-term follow-up data, including validated quality-of-life scores (EAT-10 and GIQLI), were evaluated.

Results: Overall, 97 patients underwent open surgery (OS), 37 received endoscopic surgery (ES), and 17 patients were treated conservatively. Treatment-related morbidity was 25% for OS, 5% for ES, and nil for conservative management (p = 0.004). After a median follow-up of 107 months, patients treated with OS or ES experienced less dysphagia (p < 0.001) and regurgitation (p < 0.001) compared to initial presentation. ES patients had a more favorable quality-of-life score than those treated conservatively (GIQLI: 125 vs. 106; p = 0.010 but not EAT-10: 2 vs. 6; p = 0.207). Recurrence rates were 28% for OS, 62% for ES, and 65% for conservative treatment (p < 0.001). OS was identified as an independent prognostic factor for improved recurrence-free survival.

Conclusion: Despite higher short-term morbidity, OS was associated with the best recurrence-free survival. Long-term symptoms and quality-of-life outcomes were favorable and comparable between OS and ES.

Background: Neoadjuvant chemoradiotherapy (nCRT) or perioperative chemotherapy followed by surgical resection is the standard of care for oesophageal and gastroesophageal junction cancer. Up to a third of patients will have a pathological complete response to neoadjuvant treatment. Given the significant morbidity associated with surgery, active surveillance is considered as a potential alternative for patients with clinical complete response post-nCRT. Summary: The preSANO and preSINO trials have validated a multimodal diagnostic strategy combining oesophagogastroduodenoscopy with bite-on-bite biopsies, endoscopic ultrasonography with fine-needle aspiration of suspicious lymph nodes, and PET-CT to detect residual disease. The SANO trial is assessing whether active surveillance leads to non-inferior overall survival compared to planned surgery. Early results of randomized studies support previous retrospective reports of comparable oncological outcomes, with improved quality of life in the surveillance group. Despite concerns of increased morbidity of postponed surgery upon recurrence, recent data indicate comparable surgical outcomes of delayed oesophagectomy. Ongoing trials, including SANO-2, CELEAC, and NEEDS, aim to rationalize surveillance protocols, while SANO-3 is investigating the role of adding immunotherapy in improving response durability. Key Messages: Active surveillance represents a promising alternative to surgery for oesophageal cancer patients achieving complete clinical response after neoadjuvant therapy. While it can spare patients the morbidity of oesophagectomy and significantly improve quality of life, it requires accurate response assessment and structured follow-up. Future developments, including immunotherapy and non-invasive diagnostics, may further refine this approach and expand its safe applicability.

Introduction: Free perforation of the stomach or the duodenum usually requires emergency surgery. In fact, perforation is associated with short-term mortality and morbidity in up to 30 and 50% of patients, respectively, due to secondary peritonitis and sepsis. We hypothesized that postoperative clinical outcomes with duodenal perforation (DP) are worse than those with stomach perforation (SP). This retrospective study aimed to compare the early postoperative clinical outcomes of patients with SP and DP, focusing on morbidity and mortality, to identify differences that could indicate potential changes in surgical management.

Methods: A total of 110 patients underwent emergency surgery between 2012 and 2022 for free SP or DP. We compared the demographic, intra-, and postoperative data, including morbidity and mortality during primary hospitalization in the two groups of patients. One group consisted of patients with SP and the second group consisted of patients with DP.

Results: The incidence of any postoperative complication, the rate of planned reoperation, median operation time, as well as the median hospital stay after surgery were significantly increased in patients with DP compared to those with SP. In addition, surgical and nonsurgical complications, as well as mortality were common in the total patient population, and higher in DP than in SP patients; however, these differences were not statistically significant.

Conclusion: Common postoperative problems occurring after surgery for DP or SP are similar and often life-threatening in both situations. However, patients with DP experienced these problems significantly more often, indicating a more complex injury that required considerably more medical intervention and extended treatment.

Introduction: While the resection of colorectal liver metastases is a well-established procedure, with survival rates superior to chemotherapy alone, controversial data still exist on liver resection for non-colorectal liver metastases (NCRLM). These patients comprise a diverse and heterogeneous group usually excluded from surgery. To date, only few retrospective reports are available on the surgical treatment of NCRLM. The NONCOLMET study aimed to build a comprehensive registry of patients undergoing liver resection for NCRLM, providing robust retrospective and prospective data to describe clinical practices, outcomes, and identify prognostic factors.

Methods: The study consists of two phases: (1) retrospective collection of data from patients treated between 2010 and 2024 and (2) prospective enrolment from 2025. Patients aged ≥18 years with histologically confirmed NCRLM undergoing liver resection will be included. Data will be recorded via a standardized electronic case report form on the RedCap platform. The following endpoints will be evaluated: oncological outcomes including overall survival, disease-free survival, and disease relapse; post-operative mortality at 30 and 90 days with causes of death; post-procedural complications; predictor variables of short- and long-term outcomes. These outcomes will be used to elaborate a risk score model.

Conclusions: NONCOLMET will offer crucial insights into the surgical management of NCRLM, helping refine patient selection criteria and informing future clinical guidelines.
