Background: The safety and feasibility of robotic pancreatoduodenectomy (RPD) in high-risk patients with postoperative pancreatic fistula (POPF) have rarely been investigated, although the rate of POPF is lower than in open pancreatoduodenectomy (OPD). This study aimed to examine the impact of robotic surgery on POPF in high-risk patients after pancreatoduodenectomy (PD).

Methods: This retrospective analysis included 204 patients who underwent RPD between January 2018 and June 2023. Of the 204 patients, 126 with high-risk POPF were included. The outcomes of RPD and OPD were compared. Multivariate analyses were conducted to identify risk factors associated with the development of clinically relevant POPF (CR-POPF) after surgery.

Results: Of the 126 patients, 50 underwent RPD and 76 underwent OPD. The incidence of CR-POPF was significantly lower in the RPD group than in the OPD group (6.0% vs. 38.2%, P < 0.001). Multivariate analyses identified OPD as an independent risk factor associated with CR-POPF (odds ratio [OR]: 7.87, 95% confidence interval [CI]: 2.11-29.4, P = 0.002).

Conclusions: This study demonstrated the impact of robotic surgery on POPF in high-risk patients after PD. These results suggest that RPD may be significantly associated with a decreased incidence of CR-POPF in high-risk anastomoses.

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.

Background Maximum oxygen uptake (VO₂max) is a predictor for postoperative complications after esophagectomy. Cardiopulmonary Exercise Test (CPET) is the golden standard for measuring VO₂max. The alternative Steep Ramp Test (SRT) is less strenuous with several benefits, providing an estimation of VO₂max. This study aims to determine whether SRT is a reliable alternative for CPET to evaluate preoperative fitness. Methods A total of 113 patients were included in this study. The agreement between SRT and CPET was analyzed using a t-test, Intraclass Correlation Coefficient (ICC), and the Bland-Altmann analysis. The threshold for adequate preoperative fitness was set at 17.0 ml/kg/min Results The mean difference between CPET and SRT was 2.77 ml/kg/min (95% CI 2.14-3.41). The ICC was 0.79 (95% CI 0.70-0.85). The upper limit of agreement of the Bland-Altmann was 9.44. The addition of 9.44 to the CPET-threshold gives an SRT-threshold of 26.44 ml/kg/min. Thirty-one (27.4%) patients scored higher than the SRT-threshold. Conclusion The SRT VO2max differs from VO₂max as measured by CPET. However, the difference was found to be clinically irrelevant for a substantial portion of patients. Hence, SRT is a promising alternative to CPET for determining physical fitness, and might render CPET obsolete for fit individuals.

Introduction: To investigate the current evidence regarding long-term outcomes using laparoscopic peritoneal lavage (LPL) versus primary bowel resection (PR) in Hinchey III diverticulitis.

Methods: A systematic review was undertaken based upon articles published between 1st January 2000 and 1st March 2024. Databases Pubmed, Scopus and Embase were used employing the key search terms "diverticulitis" and "peritoneal lavage". Articles were selected according to the PRISMA guidelines and statistical analysis was undertaken. Cumulative analysis of diverticulitis recurrence and secondary outcomes of disease-related mortality, serious adverse events, stoma incidence, re-operation and re-admission rates were performed.

Results: An initial search identified 506 articles for review. A total of 294 patients were included for final analysis from 3 prospective randomised controlled trials. There was no significant difference in disease-related mortality or serious adverse events between LPL and PR. There was significantly decreased likelihood of having a stoma in the LPL group however there was also a significantly increased likelihood of having recurrent diverticulitis. There was heterogenicity throughout.

Conclusion: There is a paucity of level 1 evidence available regarding the long-term outcomes of Hinchey III diverticulitis managed with LPL. At 3-year follow-up there is a significantly decreased likelihood of having a stoma, tempered by the fact that there is a significantly increased likelihood of having recurrent diverticulitis. Further homogenous high-quality randomised studies are required to clarify whether LPL shows long term benefit.

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: Partial hepatectomy (PH) remains associated with complication rates around 30-50%. Delayed return of gastrointestinal function (DRGF) has been reported in 10-20%. This study aimed to assess DRGF predictors after PH.

Methods: This study included all consecutive adult patients undergoing PH between January 01, 2010, and December 12, 2019. DRGF was defined as the need for postoperative nasogastric tube (NGT) insertion. Patients leaving the operation room with a NGT were excluded. Independent DRGF predictors were identified with multivariable logistic binary regression.

Results: A total of 501 patients were included. DRGF occurred in 82 patients (16%). Among DRGF patients, 17% (n = 14) needed a second NGT placement. DRGF incidences were similar before and after Enhanced Recovery after Surgery implementation in 2013 (16/78 = 20% vs. 66/423 = 16%, p = 0.305). A hundred-and-twelve patients (22%) underwent a minimally invasive approach and DRGF incidence was significantly lower in this group (5/112 = 4.5% vs. 77/389 = 19.8%, p < 0.001). DRGF was more frequent after major PH (55/238 = 23% vs. 27/263 = 10%, p < 0.001). DRGF occurred more often in patients with preoperative embolization (26/88 = 30% vs. 55/407 = 14%, p < 0.001), biliary anastomosis (20/48 = 42% vs. 61/450 = 14%, p < 0.001), and extrahepatic resection (37/108 = 34% vs. 45/393 = 11%, p < 0.001). Patients with DRGF had longer median operation duration (374 vs. 263 min, p < 0.001), more biliary leaks/bilomas (27/82 = 33% vs. 33/419 = 7.9%, p < 0.001), and higher median blood loss (1,088 vs. 701 mL, p < 0.001). DRGF patients developed more pneumonia (14/22 = 64% vs. 8/22 = 36%, p < 0.001) and had longer median length of stay (19 vs. 8 days, p < 0.001). On multivariable analysis, operation duration (OR 1.005, 95% CI: 1.002-1.008, p < 0.001), major hepatectomy (OR 3.606, 95% CI: 1.931-6.732), and postoperative biloma/biliary leak (OR 6.419, 95% CI: 3.019-13.648, p < 0.001) were independently associated with DRGF occurrence.

Conclusion: Postoperative DRGF occurred in 16% of the patients and was associated with a longer length of stay. Surgery duration, major PH and postoperative biloma/biliary leak were found as independent predictors of DRGF.

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.

Background: Prognosis of perihilar cholangiocarcinoma (PHCC) is poor, and curative-intent resection is the most effective treatment associated with long-term survival. Surgery is technically demanding since it involves a major hepatectomy with en bloc resection of the caudate lobe and extrahepatic bile duct. Furthermore, to achieve negative margins, it may be necessary to perform concomitant vascular resection or pancreatoduodenectomy. Despite this aggressive approach, recurrence is often observed, considering 5-year recurrence-free survival below 15% and 5-year overall survival that barely exceeds 40%.

Summary: The literature reports that survival rates are better in patients with negative margins, and surprisingly, R0 resections range between 19% and 95%. This variability is probably due to different surgical strategies and the pathologist's expertise with specimens. In fact, a proper pathological examination of residual disease should take into consideration both the ductal and the radial margin (RM) status. Currently, detailed pathological reports are lacking, and there is a likelihood of misinterpreting residual disease status due to the missing of RM description and the utilization of various definitions for surgical margins.

Key messages: The aim of PHCC surgery is to achieve negative margins including RM. More clarity in reporting on RM is needed to define true radical resection and consistent design of oncological studies for adjuvant treatments.

Introduction: Cholangiocarcinoma is the second most common primary liver tumour worldwide with an increasing incidence in recent decades. While the effects of fibrosis on hepatocellular carcinoma have been widely demonstrated, the impact on cholangiocarcinoma remains unclear. The aim of this study was to evaluate the impact of liver fibrosis on overall survival (OS) and disease-free survival (DFS) in patients who have undergone liver resection for cholangiocarcinoma.

Methods: Eighty patients with cholangiocarcinoma who underwent curatively intended liver surgery between January 2007 and December 2020 were included in this retrospective single-centre study. Clinical and histopathological features were analysed. The primary endpoint was cause-specific survival. Secondary endpoints were DFS and identification of prognostic factors.

Results: The present study shows that the median OS is significantly reduced in patients with fibrosis (p < 0.001). The median OS in patients with fibrosis was three times shorter than in the group without fibrosis. In addition, a significantly shorter DFS was observed in patients with fibrosis (p < 0.002). Multivariate analysis showed that fibrosis is the strongest independent factor with a negative impact on OS and DFS.

Conclusion: Liver fibrosis has a significant impact on OS and DFS in patients with cholangiocarcinoma. Patients with known liver fibrosis require thorough perioperative care and postoperative follow-up.

Introduction: This study aimed to evaluate associations between frailty and outcomes in patients with intrahepatic cholangiocarcinoma (ICC) undergoing hepatic lobectomy using a large, nationally representative sample.

Methods: This population-based, retrospective observational study extracted the data of adults ≥20 years old with ICC undergoing hepatic lobectomy from the US Nationwide Inpatient Sample database between 2005 and 2018. Frailty was assessed by the validated Hospital Frailty Risk Score (HFRS). Associations between frailty and surgical outcomes were analyzed using logistic regression analyses.

Results: After exclusions, 777 patients were enrolled, including 427 frail and 350 non-frail. Patients' mean age was 64.5 (±0.4) years and the majority were males (51.1%) and whites (76.5%). Frailty was significantly associated with increased odds of in-hospital mortality (aOR: 18.51, 95% CI: 6.70, 51.18), non-home discharge (aOR: 3.58, 95% CI: 2.26, 5.66), prolonged LOS (aOR: 5.56, 95% CI: 3.87, 7.99), perioperative cardiac arrest/stroke (aOR: 5.44, 95% CI: 1.62, 18.24), acute respiratory distress syndrome (ARDS)/respiratory failure (aOR: 3.88, 95% CI: 2.40, 6.28), tracheostomy/ventilation (aOR: 3.83, 95% CI: 2.23, 6.58), bleeding/transfusion (aOR: 1.67, 95% CI: 1.24, 2.26), acute kidney injury (AKI) (aOR: 14.37, 95% CI: 7.13, 28.99), postoperative shock (aOR: 4.44, 95% CI: 2.54, 7.74), and sepsis (aOR: 11.94, 95% CI: 6.90, 20.67).

Discussion/conclusion: Among patients with ICC undergoing hepatic lobectomy, HFRS-defined frailty is a strong predictor of worse in-patient outcomes, including in-hospital death, prolonged LOS, unfavorable discharge, and complications (perioperative cardiac arrest/stroke, ARDS/respiratory failure, tracheostomy/ventilation, bleeding/transfusion, AKI, postoperative shock, and sepsis). Study results may help stratify risk in frail patients undergoing hepatic resection for ICC.
