Abstract
BACKGROUND Robotic distal pancreatectomy has increasingly been accepted as it has overcome some of the limitations of open distal pancreatectomy, whilst the outcomes following robotic radical antegrade modular pancreatosplenectomy (RAMPS) in patients with pancreatic ductal adenocarcinoma (PDAC) are still uncertain. This study aimed to evaluate the short and long-term outcomes of robotic RAMPS and open RAMPS for PDAC. METHODS The patients who underwent robotic RAMPS and open RAMPS for PDAC at our clinical centre between January 2017 and December 2021 were reviewed. After a propensity score matching (PSM) at a 1:1 ratio, the perioperative and pathological outcomes in the both groups were reviewed. Univariable and multivariable Cox regression analyses were used to identify independent prognosis factors for overall survival (OS) and recurrence-free survival (RFS) of these patients. RESULTS 318 cases were recorded in robotic and open groups. The robotic group showed advantages in operative time [205.00 (166.00, 240.00) min vs 235 (184.75, 270.00) min, P = 0.002], estimated blood loss [100 (50, 100) ml vs 300 (100, 400) ml, P < 0.001], delayed gastric emptying [0 vs 5.03%, P = 0.007] and postoperative hospital stay [7.00 (5.00, 10.00) days vs 11.00 (8.00, 14.00) days, P < 0.001]. There were no significant differences in rate of severe postoperative complications between the robotic group and the open group. Multivariable analysis showed that carbohydrate antigen 19-9, estimated blood loss, N stage, tumour differentiation, chemotherapy and vascular invasion were independent risk factors for OS and RFS of these patients. CONCLUSIONS Robotic RAMPS was safe and had some advantages over open RAMPS for PDAC. There were no significantly differences in oncological outcomes and long-term survival rates between the robotic and open groups. Robotic RAMPS expanded the indications for minimally invasive surgeries for PDAC to a certain extent.

Abstract
OBJECTIVES The study aim to investigate whether elderly patients with resectable pancreatic ductal adenocarcinoma (PDAC) could benefit from postoperative chemotherapy. METHODS This study selects the data of PDAC patients who were diagnosed between 2004 and 2014 from the Surveillance, Epidemiology, and End Results program. Median overall survival (mOS) is determined by Kaplan-Meier survival curves. Multivariate logistic regression analysis and hazard ratio are employed to assess the association among potential prognostic factors. Propensity score matching evaluation is used to reduce bias. RESULTS In total, there are 11,865 PDAC patients selected from the Surveillance, Epidemiology, and End Results database. Elderly PDAC patients have poor prognoses compared with younger (mOS, 15 vs 21 months). The possible reason might be that the elderly patients are less likely to receive postoperative chemotherapy. After propensity score matching, it is found that, for those who receive postoperative chemotherapy, although the mOS of older group is not as good as that of the younger group (mOS, 20 vs 23 months; 18-month survival rate: 53.4% vs 61.3%), the mOS of older group prolonged by postoperative chemotherapy is similar to that of younger group (9 vs 9 months). CONCLUSIONS Elderly PDAC patients (≥70 years) might benefit from the currently used postoperative chemotherapy regimens.

Abstract
BACKGROUND Postoperative complications affect long-term prognosis in patients with esophageal squamous cell carcinoma (ESCC). Although a comprehensive estimator can predict long-term prognosis, the Clavien-Dindo classification system, a widely used approach to evaluate complications, assesses each complication individually. We aimed to clarify the utility of the comprehensive complication index (CCI) on predicting the overall survival (OS) of patients with ESCC following minimally invasive esophagectomy (MIE). METHODS This was a retrospective study of patients undergoing MIE for ESCC in the prone position between January 2011 and December 2018. Multivariate analyses using the Cox proportional hazards model were performed to determine independent risk factors for OS. RESULTS The study cohort included 229 patients who were categorized into patients with CCI values of ≥ 33.7 (CCI high) and < 33.7 (CCI low) by receiver-operating characteristic (ROC) curve analysis. There were no significant differences between the two groups according to clinicopathological factors, such as sex, age, tumor location, tumor depth, lymph node metastasis, and neoadjuvant chemotherapy. The intraoperative transfusion rate in the CCI high group was significantly higher than in the CCI low group. The 5 year OS rate was significantly lower in the CCI high group than in the CCI low group (49.5% vs. 65.7%, p = 0.030). By multivariate analyses, age, tumor depth, lymph node metastasis, and the CCI were independent predictors of OS. CONCLUSIONS Comprehensive assessment of postoperative complications using the CCI was useful in predicting OS of patients undergoing MIE for the ESCC.

Abstract
BACKGROUND/AIMS Postoperative abdominal fluid collection (PAFC) is a frequent complication of pancreatobiliary cancer surgery. The effects of the existence and duration of PAFC are not well known. This study aimed to assess the effects of PAFC on patient prognosis after surgery for pancreatobiliary adenocarcinoma and the association of longstanding PAFC with the recurrence of pancreatic cancer. METHODS We retrospectively analyzed the data of 194 consecutive patients with pancreatobiliary adenocarcinoma who underwent curative operations from August 2005 to December 2019. The presence of PAFC was assessed using computed tomography within a week of surgery; PAFC lasting > 4 weeks was defined as longstanding PAFC. RESULTS Among 194 patients, PAFC occurred in 165 (85.1%), and 74 of these had longstanding PAFC. The recurrence rate of pancreatobiliary adenocarcinoma was significantly higher in patients with longstanding PAFC than in patients with non-longstanding PAFC (p = 0.025). Recurrence was also significantly associated with high T stage (T3, T4; p = 0.040), lymph node involvement (p < 0.001), perineural invasion (p < 0.006), and non-receipt of adjuvant chemotherapy (p = 0.025). Longstanding PAFC was significantly associated with the recurrence of pancreatic adenocarcinoma (p = 0.016). However, cancer-specific survival was related to neither the presence nor the duration of PAFC. CONCLUSION The presence of longstanding PAFC was associated with the recurrence of pancreatic adenocarcinoma. However, a larger prospective study is necessary to confirm the findings.

Abstract
Patients undergoing complex gastrointestinal surgery are at high risk of major postoperative complications (e.g., anastomotic leakage, sepsis), classified as Clavien-Dindo (CD) ≥ IIIa. Identification of preoperative risk factors can lead to the identification of high-risk patients. These risk factors can also be used to design personalized perioperative care. This systematic review focuses on the identification of these factors. The Medline and Embase databases were searched for prospective, retrospective cohort studies and randomized controlled trials investigating the effect of risk factors on the occurrence of major postoperative complications and/or mortality after complex gastrointestinal cancer surgery. Risk of bias was assessed using the Quality in Prognostic Studies tool. The level of evidence was graded based on the number of studies reporting a significant association between risk factors and major complications. A total of 207 eligible studies were retrieved, identifying 33 risk factors for major postoperative complications and 13 preoperative laboratory results associated with postoperative complications. The present systematic review provides a comprehensive overview of preoperative risk factors associated with major postoperative complications. A wide range of risk factors are amenable to actions in perioperative care and prehabilitation programs, which may lead to improved outcomes for high-risk patients. Additionally, the knowledge of this study is important for benchmarking surgical outcomes.

Abstract
BACKROUND The influence of postoperative morbidity on survival after potentially curative resection for pancreatic ductal adenocarcinoma (PDAC) remains unclear. METHODS Medline, Web of Science and Cochrane Library were searched for studies reporting survival in patients with and without complications, defined according to the Clavien-Dindo classification, after primary, potentially curative resection for pancreatic cancer followed by adjuvant treatment. Meta-analysis was performed using a random-effects model. RESULTS Fourteen retrospective cohort studies comprising a total of 7.604 patients with an overall complication rate of 40.8% (n = 3.103 patients) were included. Median overall survival for the entire patient cohort ranged from 15.5 to 24 months. Overall survival in patients with severe postoperative complications ranged from 7.1 to 37.1 months and was significantly worse compared to the overall survival in patients without severe complications ranging from 16.5 to 38.2 months. Postoperative complication rates ranged from 24.3% to 64%, severe (Clavien-Dindo ≥ III) complication rates from 4.2% to 31%. Results sufficient for meta-analysis were reported by ten studies, representing 6.028 patients. Meta-analysis showed reduced overall survival following any complication (summary adjusted HR 1.47; 95% CI 1.23-1.76, p < 0.0001). Hazard of death was 1.5 times higher in patients experiencing severe postoperative complications than in patients without severe complications (summary adjusted HR 1.45; 95% CI 1.13-1.85, p = 0.003). CONCLUSIONS Postoperative complications after potentially curative resection of PDAC are significantly associated with worse overall patient survival.

Abstract
Perioperative medicine is a patient-centered, multidisciplinary and integrated clinical practice that starts from the moment of contemplation of surgery until full recovery. Every perioperative phase (preoperative, intraoperative and postoperative) must be studied and planned in order to optimize the entire patient management. Perioperative optimization does not only concern a short-term outcome improvement, but it has also a strong impact on long term survival. Clinical cases variability leads to the collection and analysis of a huge amount of different data, coming from multiple sources, making perioperative management standardization very difficult. Artificial Intelligence (AI) can play a primary role in this challenge, helping human mind in perioperative practice planning and decision-making process. AI refers to the ability of a computer system to perform functions and reasoning typical of the human mind; Machine Learning (ML) could play a fundamental role in presurgical planning, during intraoperative phase and postoperative management. Perioperative medicine is the cornerstone of surgical patient management and the tools deriving from the application of AI seem very promising as a support in optimizing the management of each individual patient. Despite the increasing help that will derive from the use of AI tools, the uniqueness of the patient and the particularity of each individual clinical case will always keep the role of the human mind central in clinical and perioperative management. The role of the physician, who must analyze the outputs provided by AI by following his own experience and knowledge, remains and will always be essential.

Is Laparoscopic Pancreaticoduodenectomy Feasible for Pancreatic Ductal Adenocarcinoma? Cancers (Basel) 2020; 12:cancers12113430.

Abstract
Simple Summary Pancreatic cancer is known to be one of the most lethal malignant diseases in gastrointestinal tract. Margin-negative pancreatectomy followed by postoperative adjuvant chemotherapy is essential treatment for long-term survival. Due to anatomical complexity and technical difficulty, laparoscopic pancreaticoduodenectomy is still controversial. However, with the advance of laparoscopic surgery, laparoscopic pancreatic resection of pancreatic head cancer has been carefully applied in well selected patients. The accumulating data are suggesting its technical feasibility, safety, and potential equivalent long-term oncologic outcome. In this review, the current status of laparoscopic pancreaticoduodenectomy for pancreatic head cancer is summarized. In addition, potential surgical indications and future perspectives of laparoscopic pancreaticoduodenectomy for pancreatic cancer are discussed for safe implementation in our clinical practice. Abstract Margin-negative radical pancreatectomy is the essential condition to obtain long-term survival of patients with pancreatic cancer. With the investigation for early diagnosis, introduction of potent chemotherapeutic agents, application of neoadjuvnat chemotherapy, advancement of open and laparoscopic surgical techniques, mature perioperative management, and patients’ improved general conditions, survival of the resected pancreatic cancer is expected to be further improved. According to the literatures, laparoscopic pancreaticoduodenectomy (LPD) is also thought to be good alternative strategy in managing well-selected resectable pancreatic cancer. LPD with combined vascular resection is also feasible, but only expert surgeons should handle these challenging cases. LPD for pancreatic cancer should be determined based on surgeons’ proficiency to fulfil the goals of the patient’s safety and oncologic principles.

Abstract
Survival data for pancreatic cancer are usually based on actuarial calculations and actual long-term survival rates are rarely reported. Here we use population-level data from the Surveillance, Epidemiology, and End Results program for patients with microscopically confirmed pancreatic ductal adenocarcinoma diagnosed from 1975 to 2011. A total of 84,275 patients with at least 5 years of follow-up were evaluated (follow-up cutoff date: December 31, 2016). Actual 5-year survival for pancreatic cancer increased from 0.9% in 1975 to 4.2% in 2011 in patients of all stages (p < 0.001), while in surgically resected patients, it rose from 1.5% to 17.4% (p < 0.001). In non-resected patients, the actual 5-year survival remained unchanged over the same time period (0.8% vs 0.9%; p = 0.121). Multivariable analysis of surgically resected patients diagnosed in the recent time era (2004-2011) showed that age, gender, grade, tumour size, TNM-stage and chemotherapy were significant independent predictors of actual 5-year survival, while age, grade and TNM-stage were significant independent predictors in non-resected patients. However, unfavourable clinicopathological factors did not preclude long-term survival. Collectively, our findings indicate that actual 5-year survival for pancreatic cancer is still below 5% despite improvement of survival for the subset of patients undergoing surgical resection.
