The prevalence and risk factors associated with zinc deficiency after pancreatic surgery.

To clarify the prevalence, risk factors, and clinical implications associated with zinc deficiency in patients undergoing pancreatic surgery. The serum zinc levels were measured in 329 patients post-pancreatic surgery between January and April 2021. The postoperative serum zinc levels and clinicopathological variables were retrospectively analyzed. The median serum zinc level was 73µg/dL (33-218). Zinc deficiency (zinc level < 60µg/dL) was observed in 52 patients (16%). A total of 329 patients were classified into zinc-deficient (n = 52) and non-deficient (zinc ≥ 60µg/dL, n = 277) groups. A univariate analysis revealed significant differences in sex, postoperative body mass index, serum albumin, total cholesterol, creatinine, aspartate aminotransferase (AST), HbA1c levels, diabetes, surgical procedures, and operative blood loss. According to a multivariate analysis, male sex [odds ratio (OR) 3.70; 95% confidence interval (CI) 1.67-8.20; p = 0.001], postoperative serum albumin levels < 3.9g/dL (OR 6.39; 95% CI 3.30-12.37; p < 0.001), postoperative serum AST ≥ 51 U/L (OR, 4.6; 95% CI 0.07-0.29; p < 0.001), and total pancreatectomy (OR 3.68; 95% CI 1.37-9.85; p = 0.009) were found to be independent predictors of zinc deficiency after pancreatic surgery. Zinc deficiency frequently occurs in patients undergoing pancreatic surgery. Lower postoperative zinc levels could be linked to sex, the serum albumin and AST levels, and surgery type.

Embolize, supercharge, resect: Embolization to enhance hepatic vascularization prior to en-bloc pancreas and arterial resection

IntroductionEmbolization could increase the resectability of pancreatic tumors by supercharging visceral arterial perfusion prior to pancreatic surgery with arterial en-bloc resection. Its indications, however, are controversial. MethodsWe retrospectively analyzed the results of a single-center database of patients undergoing pancreatic surgery with arterial resection (AR) after preoperative arterial embolization (PAE) to increase hepatic vascular flow and spare arterial reconstruction. ResultsPAE was planned in 15 patients with arterial involvement due to pancreatic tumors. Three patients were excluded due to the finding of irresectable disease during surgery. Twelve cases were resected because of pancreatic cancer (10), distal cholangiocarcinoma (1), and pancreatic neuroendocrine tumor (1). Arterial involvement in these cases required embolization of the substitute right hepatic artery (RHA) (5), left hepatic artery (1), and common hepatic artery (CHA) (6) to enhance liver vascularization. Two patients presented migration of the vascular plug after PAE. Six pancreatoduodenectomies and 6 distal pancreatectomies were performed, the latter associated with en-bloc celiac trunk and CHA resection. R0 was achieved in 7 out of 12 patients, and pathological vascular involvement was confirmed in 8. Postoperative complications included one patient who developed gastric ischemia and underwent gastrectomy, and one patient who underwent reoperation for acute cholecystitis with liver abscesses. ConclusionPreoperative arterial embolization before pancreatic surgery with hepatic arterial resection enables surgeons to precondition hepatic vascularization and prevent hepatic ischemia. In addition, this avoids having to perform arterial anastomosis in the presence of pancreatic suture.

Incisional hernia after major pancreatic resection: long term risk assessment from two distinct sources – A large multi-institutional network and a single high-volume center

BackgroundPost-operative incisional hernia (IH) is a common complication following abdominal surgery. Data regarding IH after major pancreatic surgery are limited. We aim to evaluate the long-term risk of IH following major pancreatic resection. MethodsA dual-approach study: a large multi-institutional research network (RN) was investigated for IH incidence and risk factors in propensity-score matched survivors after pancreaticoduodenectomy (PD) and distal pancreatectomy (DP), was complemented by a patient-reported questionnaire. ResultsRN analysis identified 22,113 patients that underwent pancreatic surgery. 11.0% of PD patients and 8.6% of DP patients developed IH (P < 0.0001). IH rates were higher with open surgery compared with minimally invasive approaches in PD (OR = 1.56, P = 0.03) and DP (OR = 1.94, P = 0.003). BMI>35 was found to correlate with increased IH rates for PD and DP (OR = 1.87, and OR = 1.86, respectively, P < 0.0001 each), as did postoperative intraabdominal infections (P < 0.0001). Patient-based survey of 104 patients, revealed that 16 patients (15%) reported post-operative IH during the follow-up period. BMI≥30, SSI and intra-abdominal abscesses were associated with increased IH risk (P < 0.05). ConclusionImproved survival after pancreatic resection has led to an increased prevalence of long-term surgical sequela. In this study, we demonstrate significant rates of IH among long-term survivors and assess potential risk factors.

Effect of intranasal insulin on perioperative cognitive function in older adults: a randomized, placebo-controlled, double-blind clinical trial.

Postoperative cognitive impairment are common neural complications in older surgical patients and exacerbate the burden of medical care on families and society. A total of 140 older patients who were scheduled for elective orthopaedic surgery or pancreatic surgery with general anaesthesia were randomly assigned to Group S or Group I with a 1:1 allocation. Patients in Group S and Group I received intranasal administration of 400μL of normal saline or 40IU/400μL of insulin, respectively, once daily from 5minutes before anaesthesia induction until 3days postoperatively. Perioperative cognitive function was assessed using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment-Basic (MoCA-B) at 1day before and 3days after surgery and postoperative delirium (POD) incidence was assessed using the 3-minute Diagnostic Interview for CAM (3D-CAM) on postoperative days 1-3. Serum levels of interleukin-6 (IL-6), tumour necrosis factor α (TNF-α), S100-β and C-reactive protein (CRP) were measured on the first day after surgery. Insulin treatment significantly increased postoperative MMSE and MoCA-B scores in group I than in group S (P < 0.001, P = 0.001, respectively), decreased the incidence of POD within the 3-day postoperative period in Group I than in Group S (10.9% vs 26.6%, P = 0.024), and inhibited postoperative IL-6 and S100-β levels in Group I compared to Group S (P = 0.034, P = 0.044, respectively). Intranasal insulin administration is thus suggested as a potential therapy to improve postoperative cognition in older patients undergoing surgery. However, a more standardized multi-centre, large-sample study is needed to further validate these results.

The use of indocyanine green fluorescence imaging in preventing postoperative bile leakage of the hepaticojejunostomy in robot-assisted pancreatic surgery

BackgroundPostoperative bile leakage (POBL) due to insufficiency of the hepaticojejunostomy (HJ) after pancreatico-duodenectomy (PD) is associated with high morbidity and mortality. The aim of this cohort study was to determine the clinical relevance of ICG in detecting and preventing POBL of the HJ in robotic minimal invasive pancreatic surgery (R-MIPS). MethodsAll consecutive robot- and ICG-assisted HJ-anastomoses between 2019 and 2022 were included. Biliary leakage was objectified with near infrared technology. Only clinically relevant POBL were considered in this study. ResultsSixty patients who underwent a PD between 2019 and 2022 were included. In ten patients, fluorescence imaging revealed an intra-operative hepaticojejunostomy insufficiency (HJI). Five of these patients developed POBL despite revision but preventing POBL in five patients. Detection of HJI with ICG predicted POBL with a sensitivity and specificity of 41.6% and 89.6% respectively. There was a significant higher chance of developing a POBL if the hepatic duct diameter was less than 5 mm (relative risk = 4.68 (p = 0.0345)), or if an intra-operative HJI was detected (relative risk = 3.57 (p = 0.009)). ConclusionICG is a simple and useful tool for detecting intra-operative bile leakage. This study shows that bile illumination with ICG in R-MIPS could prevent postoperative bile leakage.

Causes, management, and prognosis of severe gastrointestinal bleedings in critically ill patients with pancreatic cancer: A retrospective multicenter study

BackgroundGastrointestinal (GI) bleeding is a leading cause of intensive care unit (ICU) admission in pancreatic cancer patients. AimsTo analyze causes, ICU mortality and hemostatic treatment success rates of GI bleeding in pancreatic cancer patients requiring ICU admission. MethodsRetrospective multicenter cohort study between 2009 and 2021. Patients with a recent pancreatic resection surgery were excluded. ResultsNinety-five patients were included (62 % males, 67 years-old). Fifty-one percent presented hemorrhagic shock, 41 % required mechanical ventilation. Main GI bleeding causes were gastroduodenal tumor invasion (32 %), gastroesophageal varices (21 %) and arterial aneurysm (12 %). Arterial aneurysms were more frequent in patients with previous pancreatic resection (36 % vs 2 %, p < 0.001). Hemostatic procedures included gastroduodenal endoscopy in 81 % patients and arterial embolization in 28 % patients. ICU mortality was 19 %. Multivariate analysis identified four variables associated with mortality: performance status >2 (OR 9.34, p = 0.026), mechanical ventilation (OR 14.14, p = 0.003), treatment success (OR 0.09, p = 0.010), hemorrhagic shock (OR 11.24, p = 0.010). Treatment success was 46 % and was associated with aneurysmal bleeding (OR 29.89, p = 0.005), ongoing chemotherapy (OR 0.22, p = 0.016), and prothrombin time ratio (OR 1.05, p = 0.001). ConclusionIn pancreatic cancer patients with severe GI bleeding, early identification of aneurysmal bleeding (particularly in case of previous resection surgery) and coagulopathy management may increase the treatment success and reduce mortality.

Delayed Gastric Emptying and Other Adverse Outcomes in Patients Undergoing Classic Whipple Versus Pylorus-Sparing Pancreatoduodenectomy.

Background and objective Pancreatoduodenectomy (PD), or the Whipple procedure, has many variants. There is a lack of data in the literature in terms of comparing various types of this procedure. This study aimed to comparethe classic Whipple procedure with the pylorus-sparing Transverso-Longmire technique, focusing on postoperative complications and delayed gastric emptying (DGE). Methodology We conducted a retrospective observational study including 97 adult patients who underwent either the classic Whipple procedure or the pylorus-sparing technique at Hospital Médica Sur from 2016 to 2021. Data on patient demographics, comorbidities, type of surgery, clinical presentation, and postoperative complications were collected. DGE was defined according to the International Study Group of Pancreatic Surgery(ISGPS) criteria. Results Among the 97 patients, 50.5% were men, and the median age of the cohort was 65 years. Almost all patients underwent surgery for malignancy (96.9%). The classic Whipple group had fewer cases of DGE (9.8% vs. 30.6%, p=0.01), shorter hospital stays (7 vs. 11 days, p=0.001), and lower readmission rates (13.1% vs. 33.3%, p=0.017). The pylorus-sparing PD was associated with a lower incidence of bile leak [odds ratio (OR)=0.62, 95% confidence interval (CI): 0.53-0.73]. However, this technique was associated with a higher incidence of DGE (OR=4, 95% CI: 1.34-12.1), overall hospital admission rates (OR=3.3, 95% CI: 1.2-9.2), and admissions that resulted in a surgical event (OR=1.9, 95% CI: 1.21-2.96). DGE was associated with the need for a second surgery (OR=10.5, 95% CI: 2.8-39.5) and hospital readmission (OR=10, 95% CI: 3.1-32.3). Conclusions While the pylorus-sparing technique is associated with reduced bile leaks, it results in a higher incidence of DGE, prolonged hospital stays, and increased readmissions. Clinicians opting for the pylorus-sparing technique should ensure careful patient selection and rigorous postoperative monitoring.

Abdominal drainage after minimally invasive distal pancreatectomy: out of sight, out of mind?

The use of drains in pancreatic surgery remains controversial. The present study investigated postoperative outcomes in patients undergoing minimally invasive distal pancreatectomy (MIDP) without intraperitoneal drain placement. Data of consecutive patients undergoing MIDP between 2013 and 2023 were prospectively collected. Patients were divided in drain group (DG), including patients with prophylactic abdominal drain placed, and no-drain group (NDG) including those without drain. The groups were compared in terms of postoperative outcomes, using a propensity score-matched analysis. 116 patients were selected. After matching, DG and NDG consisted of 29 patients each. The rates of POPF and abdominal collection were lower in NDG in comparison to DG (3.4% vs. 27.6%, p 0.025 and 3.4% vs. 31.0%, p 0.011, respectively). The length of stay was significantly shorter in the NDG (5 vs. 9days, p < 0.001). No difference between the groups was found for other outcomes. Drain omission was associated with lower rates of POPF and abdominal collections, as well as shorter hospital stays, not affecting the rate of severe complication, reoperation and readmission.

Benchmarking in pancreatic surgery: a systematic review of metric development and validation.

Benchmarking in healthcare, particularly in the context of complex surgical procedures like pancreatic surgery, plays a pivotal role in comparing and evaluating the quality of care provided to patients. There is a growing body of evidence validating existent metrics and introducing new ones in the pursuit of safety and excellence in pancreatic surgery. A systematic review adhering to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was conducted on metric development and validation across multiple databases, including PUBMED Medline, Scopus, and Web of Science, until February 2024. The extracted data were categorized into three domains according to the Donabedian model: structure, process, and outcomes. Thirty-four studies were deemed eligible for inclusion in this review. Among these articles, 20 contributed to metric development, while 14 studies validated them. A total of 234 metrics were identified across the 34 studies, of which 185 were included in the analysis. Thirty-three of these metrics were relative to structure, 79 to processes, and 73 to outcomes. The distribution of metric domains across the included studies revealed that structure, process, and outcome domains were reported in 12, 26, and 26 studies, respectively. In conclusion, this systematic review underscores the heterogeneity in metric development methodologies and the varying degrees of consensus among different quality indicators, despite the growing interest in benchmarking in pancreatic surgery. This review aims to inform future research efforts and contribute to the ongoing pursuit of excellence in pancreatic surgical care.

Effects of intraoperative different fluid therapy protocols on postoperative renal functions

PurposePlanning intraoperative fluid therapy in patients undergoing major abdominal surgery is important. It was aimed to define the difference between fluid therapy protocols for renal function, bleeding and postoperative service follow-ups.Materials and methodsThis is an observational case-controlled prospective study. Sixty patients aged 18–65 years who had undergone pancreatic surgery between December 2023– February 2023 were included in the study. Liberal (Group 1; n = 30) and targeted fluid therapies (Group 2; n = 30) were administered to the patients. Liberal fluid therapy was planned with 8–10 ml/kg/h crystalloid infusion. The targeted fluid therapy (TFT) group (Group 2; n = 30) began with a 2 ml/kg/h crystalloid infusion at the baseline. Additional fluid boluses were given in 250 ml of colloid infused over 10 min if PVI was > 13% for at least five minutes. The patients were staged using the KDIGO (Kidney Disease: Improving Global Outcomes) criteria. The amount of bleeding during surgery was recorded for both groups.ResultsNo significant difference was observed in postoperative renal function. A significant difference was observed in the amount of intraoperative bleeding. The amount of bleeding was greater in patients managed with liberal fluid therapy. No significant difference was observed between the groups in the oral intake (hour), drain withdrawal (hour) mobilization (hour) and discharge (day) times and there isn’t any statistically significant differance between groups in cost effectivity (p>0.05).ConclusionKidney function was preserved during individualized targeted fluid therapy using non-invasive haemodynamic monitoring parameters.

Can we “prehabilitate” pancreatic cancer patients prior to surgery? A critical appraisal of the literature

BackgroundEnhancing a patient’s functional capacity to withstand the surgical stress by means of multimodal (combined exercise, nutrition and psychological interventions) prehabilitation may potentially lead to improved outcomes in pancreatic cancer surgery. MethodologyA systematic review was undertaken searching PubMed, Google Scholar and Cochrane Library databases, exploring the impact of prehabilitation in pancreatic surgery. Outcomes of interest were adherence to the prehabilitation, functional capacity, overall complications and post-operative length of stay. Pooled analysis was performed using a random-effects model. ResultsTwelve studies comprising of 1497 patients were included in the review. Most of the studies seem to lack a multimodal approach. Less than 50 % of the studies reported adherence, which ranged between 27 to 100 %. Functional capacity, in terms of 6-minute walk test, showed improvement with prehabilitation. Among the post-operative outcomes, prehabilitation was associated with significant improvement in pulmonary complications (2.4 % versus 6.7 %, RR 0.36, CI 0.17-0.74, p= 0.01, I2= 28%). Prehabilitation was not effective in terms of length of stay or readmission rates. ConclusionsLarger studies with multimodal prehabilitation approaches may demonstrate more consistent and clinically meaningful benefits, which would lead to a firm appreciation of its role the management of pancreatic cancer patients undergoing surgery.

Study protocol of the FRENCH24-ANIS study: postoperative anti-infective strategy following pancreaticoduodenectomy in patients with preoperative biliary stents—an intergroup FRENCH-ACHBT-SFAR prospective randomized controlled trial

BackgroundDespite advances in surgical techniques and care, pancreatoduodenectomy (PD) continues to have high morbidity and mortality rates. Complications such as sepsis, hemorrhage, pulmonary issues, shock, and pancreatic fistula are common postoperative challenges. A key concern in PD outcomes is the high incidence of infectious complications, especially surgical site infections (SSI) and postoperative pancreatic fistula (POPF). Bacteriobilia, or bile contamination with microorganisms, significantly contributes to these infections, increasing the risk of early postoperative complications. The occurrence of SSI in patients who undergo hepatobiliary and pancreatic (HPB) surgeries such as PD is notably higher than that in patients who undergo other surgeries, with rates ranging from 20 to 55%. Recent research by D'Angelica et al. revealed that, compared to cefoxitin, piperacillin/tazobactam considerably lowers the rate of postoperative SSI. However, these findings do not indicate whether extending the duration of antibiotic treatment is beneficial for patients at high risk of bacterial biliary contamination. In scenarios with a high risk of SSI, the specific agents, doses and length of antibiotic therapy remain unexplored. The advantage of prolonged antibiotic prophylaxis following PD has not been established through prospective studies in PD patients following biliary drainage.MethodsThis is an intergroup FRENCH-ACHBT-SFAR multicenter, open-labelled randomized, controlled, superiority trial comparing 2 broad-spectrum antibiotic (piperacillin/tazobactam) treatment modalities to demonstrate the superiority of 5-day postoperative antibiotic therapy to antibiotic prophylaxis against the occurrence of surgical site infections (SSI) following pancreaticoduodenectomy in patients with preoperative biliary stents. The primary endpoint of this study is the overall SSI rate, defined according to the ACS NSQIP, as a composite of superficial SSI, deep incisional SSI, and organ/space SSI.In addition, we will analyze overall morbidity, antibiotic resistance profiles, the pathogenicity of bacteriological and fungal cocontamination, the impact of complications after bile drainage and neoadjuvant treatment on the bacteriological and fungal profile of biliculture and cost-effectiveness.ConclusionThis FRENCH24-ANIS study aims to evaluate 5-day post-operative antibiotic therapy combined with antibiotic prophylaxis on the occurrence of surgical site infections (SSI) following pancreaticoduodenectomy in patients with preoperative biliary stents.Trial registrationClinicaTrials.gov number, NCT06123169 (Registration Date 08–11–2023); EudraCT number 2021–006991-18; EUCT Number: 2024–515181-14–00.

Outcomes following pancreaticoduodenectomy for octogenarians: a systematic review and meta-analysis

BackgroundAn increasing number of elderly patients are being diagnosed with pancreatic cancer, with increasing need to consider pancreatic surgery. This study aims to provide an updated systematic review and meta-analysis to evaluate the outcomes following pancreaticoduodenectomy in octogenarians. MethodsA systematic review and meta-analysis was performed via a search of Medline, PubMed and Cochrane databases. Studies comparing outcomes of patients >80 years to younger patients undergoing PD were included. Results26 studies were included. This included 22481 patients, with 20134 (89.6%) aged <80 years old, and 2347 (10.4%) octogenarians. Octogenarians were associated with higher rates of mortality (OR 2.37 (95%CI 1.91-2.94, p < 0.00001)), all-cause morbidity (OR 1.60 (95%CI 1.30-1.96), p<0.00001) and re-operation (OR 1.41 (95%CI 1.13-1.75), p = 0.002). Octogenarians had a two-fold risk of cardiac complications and respiratory complications (OR 2.13 (95%CI 1.67-2.73), p < 0.00001), (OR 2.38 (95%CI 1.72-3.27), p < 0.0001). There was no difference in postoperative pancreatic fistula, post-pancreatectomy hemorrhage or delayed gastric emptying. Younger patients were more likely to return to adjuvant therapy (OR 0.20 (95%CI 0.12-0.34), p < 0.00001). ConclusionsOctogenerians are associated with higher mortality rate, postoperative complications, and reduced likelihood to undergo adjuvant therapy. Careful preoperative assessment and selection of elderly patients for consideration of pancreatic surgery is essential.

Consensus guidelines on the diagnosis and treatment of pancreatic pseudocyst and walled-off necrosis from a Chinese multiple disciplinary team expert panel.

To prepare a set of practice guidelines to standardize the entire process, from diagnosis to treatment and follow-up, for pancreatic pseudocysts and walled-off necrosis. Thirty-six experts in the fields of digestive endoscopy, pancreatic surgery, interventional radiology, and others presented their opinions via discussions in online conferences by referring to the patient, intervention, comparison, and outcomes principles and then reviewed the evidence and statements using the Delphi method to reach a consensus. The consensus of >80% was finally achieved for the items. The experts discussed and reached a consensus on 29 statements including 10 categories: (1) definition and classification, (2) imaging and endoscopic diagnosis, (3) therapeutic implications, (4) surgical therapy, (5) percutaneous catheter drainage, (6) endoscopic retrograde cholangiopancreatography, (7) EUS-guided drainage, (8) stent selection for EUS-guided drainage, (9) complication related to stents for cyst drainage, and (10) drug treatment and follow-up. This consensus based on the clinical experience of experts in various fields and international evidence-based medicine further standardizes the multidisciplinary diagnosis and treatment processes for pancreatic pseudocysts and walled-off necrosis.

Validation and Optimisation of the ISGPS Risk Classification for Postoperative Pancreatic Fistula after Pancreatoduodenectomy for Periampullary Tumours.

To externally validate the International Study Group of Pancreatic Surgery (ISGPS) classification and test its performance for predicting clinically relevant pancreatic fistula (CRPF) for periampullary tumours (P-amps). The ISGPS is a simple two-factor, four-tier classification of pancreas-related risk for CRPF after a pancreatoduodenectomy (PD). External validation and performance of the classification specific to P-amps are lacking. P-amps have different disease biology, lesser need for neoadjuvant therapy, softer pancreas, and a higher rate of CRPF, underscoring the importance of site-specific prediction. Validation was performed in a cohort of 1422 patients, with CRPF as the primary outcome. Model performance was tested by plotting the receiver operating curve and calibration plots. After analysing the factors predicting CRPF, the model was optimised for P-amps. CRPF rate was 22.2% (315/1422), for P-amps being 25.8%. The ISGPS model performed moderately (AUC=0.632, 95% CI 0.598-0.666, P<0.001), with worse performance for P-amps (AUC=0.605, 95% CI 0.566-0.645, P<0.001). On multivariate analysis, soft pancreas (OR 1.689, 95% CI 1.136-2.512, P=0.010), body mass index ≥23kg/m2 (OR 2.112, 95% CI 1.464-3.046, P<0.001) and pancreatic duct ≤3mm (OR 2.113 95% CI 1.457-3.064, P<0.001), emerged as independent predictors and the model was optimised. The adjusted ISGPS for P-amps showed improved discrimination (AUC=0.672, P<0.001, 95% CI 0.637-0.707), with adequate performance on internal validation. The adjusted ISPGS performs better than the original ISGPS in predicting CRPF for P-amps. Large-scale multicenter data is needed to generate and validate site-specific predictive models.

The Effect of Case Management Model on the Application of Pancreatic Cancer Surgery Patients and the Recovery of Gastrointestinal Function

Objective: To evaluate the effect of the case management model on patients operated for pancreatic cancer. Methods: 90 pancreatic cancer surgery patients admitted to the hospital between January 2022 and June 2023 were selected and grouped by randomized numerical table. For 45 cases in the observation group, case management mode was adopted, and for 45 cases in the intervention group, conventional nursing care was chosen to compare the indexes of gastrointestinal function recovery. Results: The recovery time of all gastrointestinal functions of the observation group was shorter than that of the intervention group; after nursing, the psychological state score of the observation group was lower than that of the intervention group, the self-efficacy score was higher than that of the intervention group and the rate of complications was lower than that of the intervention group (P &lt; 0.05). Conclusion: The case management model can promote the recovery of gastrointestinal function in patients with pancreatic cancer surgery and its nursing feasibility is high.

Robotic surgery reduces the consumption of medical consumables: cost analysis of robotic pancreatic surgery from a tertiary hospital in China.

Robotic surgery has been increasingly adopted in various surgical fields, but the cost-effectiveness of this technology remains controversial due to its high cost and limited improvements in clinical outcomes. This study aims to explore the health economic implications of robotic pancreatic surgery, to investigate its impact on hospitalization costs and consumption of various medical resources. Data of patients who underwent pancreatic surgery at our institution were collected and divided into robotic and traditional groups. Statistical analyses of hospitalization costs, length of stay, costs across different service categories, and subgroup cost analyses based on age, BMI class, and procedure received were performed using t tests and linear regression. Although the total hospitalization cost for the robotic group was significantly higher than that for the traditional group, there was a notable reduction in the cost of medical consumables. The reduction was more prominentamong elderly patients, obese patients, and those undergoing pancreaticoduodenectomy, which could be attributed to the technological advantages of the robotic surgery platform that largely facilitate blood control, tissue protection, and suturing. The study concluded that despite higher overall costs, robotic pancreatic surgery offers significant savings in medical consumables, particularly benefiting certain patient subgroups. The findings provide valuable insights into the economic viability of robotic surgery, supporting its adoption from a health economics perspective.

Optimizing terminology for pancreatectomy: Introducing a new notation system.

We introduce a novel notation system for pancreatectomy designed to provide a clear and concise representation of surgical procedures. As surgical techniques and the scope of pancreatic surgeries continue to diversify, existing communication methods among medical professionals regarding the specifics of the surgeries have proven inadequate. Our proposed notation system clearly indicates the approach (open, laparoscopic, or robot-assisted), type of surgery (e.g., pancreatoduodenectomy, distal pancreatectomy), and extent of resection and accompanying resected organs or vasculature. These elements are all recorded in this order by using abbreviations. For example, a pancreatoduodenectomy with pancreatic transection just above the SMA and combined resection of the SMV would be noted as "OPD(hb')-SMV". This new notation system allows for concise expression of the essential information on performed procedures of pancreatic resection, leading to smooth information sharing. This initiative is an essential step towards standardizing pancreatic surgery documentation on a global scale. Here, we present the development and application of this system, highlighting its potential to transform surgical communication and documentation.
