The Value of Textbook Outcome in Benchmarking Pancreatoduodenectomy for Nonfunctioning Pancreatic Neuroendocrine Tumors.

BACKGROUND: Textbook outcome (TO) is a composite variable that can define the quality of pancreatic surgery. The aim of this study is to evaluate TO after pancreatoduodenectomy (PD) for nonfunctioning pancreatic neuroendocrine tumors (NF-PanNETs). PATIENTS AND METHODS: All patients who underwent PD for NF-PanNETs (2007-2016) in different centers were included in this retrospective study. TO was defined as the absence of severe postoperative complications and mortality, length of hospital stay ≤ 19 days, R0 resection, and at least 12 lymph nodes harvested. RESULTS: Overall, 477 patients were included. The TO rate was 32%. Tumor size [odds ratio (OR) 1.696; p = 0.013], a minimally invasive approach (OR 12.896; p = 0.001), and surgical volume (OR 2.062; p = 0.023) were independent predictors of TO. The annual frequency of PDs increased over time as well as the overall rate of TO. At a median follow-up of 44 months, patients who achieved TO had similar disease-free (p = 0.487) and overall survival (p = 0.433) rates compared with patients who did not achieve TO. TO rate in patients with NF-PanNET > 2 cm was 35% versus 27% in patients with NF-PanNET ≤ 2 cm (p = 0.044). Considering only NF-PanNETs > 2 cm, patients with TO and those without TO had comparable 5-year overall survival rates (p = 0.766) CONCLUSIONS: TO is achieved in one-third of patients after PD for NF-PanNETs and is not associated with a benefit in terms of long-term survival.

Intraoperative Blood Loss Estimation in Hepato-pancreato-biliary Surgery- Relevant, Not Reported, Not Standardized: Results From a Systematic Review and a Worldwide Snapshot Survey.

OBJECTIVE: To provide an overview of the current practice of intraoperative blood loss (BL) estimation in hepato-pancreato-biliary (HPB) surgery. BACKGROUND: Intraoperative BL is a major quality marker in HPB surgery and a predictor of perioperative outcomes. However, the method for BL estimation is not standardized. METHODS: A systematic review was performed of original studies published between 2006 and 2021 reporting the intraoperative BL of patients undergoing pancreatic or hepatic resections. A web-based snapshot survey was distributed globally to all members of the International Hepato-Pancreato-Biliary Association (IHPBA). RESULTS: A total of 806 studies were included; 480 (60%) had BL as their primary outcome, and 105 (13%) had BL as their secondary outcome. However, 669 (83%) did not specify how BL estimation was performed, and 9 different methods were found among the remaining 136 (17%) studies.The survey was completed by 252 surgeons. Most of the responders (94%) declared that they systematically performed BL estimation and considered BL predictive of postoperative complications after pancreatic (73%) and liver (74%) resection. All methods previously identified in the literature were used by responders with different frequencies. A calculation based on suction fluid amounts, operative gauze weight, and irrigation was the most used method in the literature (7%) and among responders (51%). Most responders (83%) felt that BL estimation in HPB surgery needs improved standardization. CONCLUSIONS: Standardization of intraoperative BL estimation is urgently needed in HPB surgery to ensure the consistency of reporting and reproducibility.

Risk factors for nodal involvement in early-stage rectal cancer: a new scoring system based on the analysis of 326 cases.

BACKGROUND: the purpose of this study was to identify which clinicopathological features of early-stage rectal cancer (ESRC) are significantly correlated with the risk of local-regional lymph node metastases (LNM) and to quantify the strength of this association through a novel scoring system. According to several case studies, about 20% of operated ESRC are found with occult lymph nodal metastases at the histological examination. The low frequency of local recurrence in these tumors treated with total mesorectal excision (TME) compared to transanal approaches highlights the role of mesorectal lymph nodes as a site of metastatic location. METHODS: Overall, 386 consecutive patients with ESRC treated with radical resection and TME were examined in a retrospective, observational multi-centric study, operated between 2007 and 2019 in seven centers. Demographic and tumor related clinicopathological characteristics were identified, collected and analyzed. Each variable was specifically weighted based on the strength of its association with the presence of nodal metastases. A scoring system using these weighted variables was developed. RESULTS: Six variables were found to be significantly associated with local regional LNM: lymphatic invasion combined with vascular invasion, poor differentiation (G3), stage T2, age ≥60 years, male sex, perineural invasion. A novel scoring system weighted on the presence of each of these variables able to quantify the risk of LNM in ESRC was developed. CONCLUSIONS: The proposed scoring system is a good predictor of the risk of LNM and should be of help in the decision-making process for ESRC cases diagnosed either by local excision or endoscopic biopsy.

Changes in volumes and severity of surgical urgencies during the first two COVID-19 pandemic waves in a regional hospital network.

Background and aim This study analyses the impact of the first two pandemic waves on surgical urgencies/emergencies and their consequences on an entire provincial hospital network's surgical activities. Methods  Clinical and epidemiological data of urgent/emergent surgical admissions and interventions in the Autonomous Province of Trento's hospital network were collected from the internal common electronic database. The investigation periods were March-May 2019 (reference period), March-May 2020 (phase-I), June - August 2020 (phase-II), and October - December 2020 (phase-III). The same data were divided and grouped for the six most represented diagnoses. Results: The number of admissions for surgical emergencies in the studied periods showed a sinusoidal trend. In the reference period of 2019, 957 patients were admitted in urgency, while in the three pandemic phases, urgent admissions were 511, 888 and 633 respectively (-47% in phase I, - 8% in phase II, -34% in phase III). This trend was also observed by stratifying admissions for single disease, except for gastrointestinal perforations and pancreatitis, which showed a slight increasing trend in phase-I. Among the studied population, the surgical rate was 35.2% in phase-I and 34.3% in phase-III; these data were significantly higher than in 2019 (25.6%).  Conclusions The effect of the COVID pandemic on surgical emergencies and urgencies (SUEs) was mainly indirect, manifesting itself with a significant reduction in the number of surgical admissions, particularly in phases-I and-III. Conversely, in the same phases, the surgical rate showed a significant increase compared to 2019.

Impact of COVID-19 pandemic waves on changes in surgical urgency volumes and severity in the regional hospital network of Trento (Northern Italy): a descriptive epidemiological analysis.

OBJECTIVES: to analyse both direct and indirect impacts on surgical admissions, surgical rates, and clinical picture severity of the two COVID-19 pandemic waves in a hospital network covering an entire province (Trento, located in Trentino-Alto Adige Region, Northern Italy). DESIGN: retrospective epidemiological study. SETTING AND PARTICIPANTS: data regarding the patient load of the Surgical Urgencies/Emergencies flows (SUEs) of the Local Health Authority of the Autonomous Province of Trento derived from the Hospital Discharge Record (HDR) information flow. The population in study was that of patients hospitalized in the entire Province of Trento. This study compares the volume and characteristics of urgent/emergency surgery during the 2020 COVID-19 pandemic with the homologous period in 2019, subdividing the analysed pandemic period in 3 separated groups: • phase I (March-May 2020); • phase II (June-August 2020); • phase III (October-December 2020). The 3 groups represent, respectively: the 1st pandemic wave proclamation of national lockdown from 9 March to 18 May; the summer pandemic remission; the 2nd pandemic wave with partial restrictions on circulation and commercial activities. Clinical and surgical records of SUE population among these 3 periods (March-May; June-August; October-December) of both 2020 and 2019 were analyzed and compared. MAIN OUTCOME MEASURES: the overall number of admissions and surgical rates for SUEs in the study periods were chosen as primary outcomes. The same outcomes were analysed for the most represented diagnoses in the SUEs population: diverticulitis, intestinal obstruction, appendicitis, cholecystitis, gastrointestinal (GI) perforations, pancreatitis, traumas. To assess the degree of clinical picture severity, variables coming from the hospital discharging charts, commonly associated to worst outcomes in term of mortality and morbidity, such as age, length of hospital stay, DRG weight, and patients not discharged at home were extrapolated from the electronic database. A numerical weight was then assigned to each variable, obtaining a scoring system from 0 to 15 (severity index). RESULTS: the number of admissions for SUEs in the studied period showed a sinusoidal trend, with a dramatic decrease in phase I and III (-46.6% and -31.6%, respectively). This trend was also observed even by stratifying admissions for the most frequent pathologies, except for gastrointestinal perforations and pancreatitis. The surgical rate among hospitalised patients for SUEs was 35.2% in phase, significantly higher than that of 2019 (25.6%). Considering the most frequent diagnoses individually, some had a progressive increase in the surgical rate in phases I and II (diverticulitis, bowel obstructions, cholecystitis), others showed an initial decrease and then settled on values ​​not far from those of 2019 (GI perforations and appendicitis), others again had an initial significant increase and then gradually returned to values ​​similar to those of 2019 in phase III (traumas). The mean patients age was significantly higher in phase I than in 2019 (p-value <0.001) and in phase II (p-value <0.05). Consistently with the trend of the number of urgent admissions, even the severity index calculated on the SUEs population showed a sinusoidal trend with and evident increase during the two pandemic waves. CONCLUSIONS: the effect of the COVID-19 pandemic on SUEs was mainly indirect, manifesting itself with a significant reduction in surgical admissions, particularly in phases I and III. Conversely, in the same phases, the surgical rate showed a significant increase compared to 2019. The stratified analysis confirmed these findings for the most frequent diagnoses except for GI perforations and pancreatitis. The clinical pictures were more severe in the two pandemic waves than in the reference period of 2019. Although with a slight numerical attenuation, in general, the second pandemic wave confirmed the first one findings.
