Postpancreatectomy hemorrhage (PPH) is an important risk factor for postoperative complications after laparoscopic pancreaticoduodenectomy (LPD). Recent studies have reported that the use of ligamentum teres hepatis (LTH) in LPD may reduce the risk of PPH. Therefore, this study aims to investigate whether wrapping the hepatic hilar artery with the LTH can reduce PPH after LPD. We reviewed the data of 131 patients who underwent LPD in our team from April 2018 to December 2023. The patients were divided into Groups A (60 patients) and B (71 patients) according to whether the hepatic portal artery was wrapped or not. The perioperative data of the two groups were compared to evaluate the effect of LTH wrapping the hepatic hilar artery on LPD. The platelet count of Group A was (225.25 ± 87.61) × 10^9/L, and that of Group B was (289.38 ± 127.35) × 10^9/L, with a statistically significant difference (p < 0.001). The operation time of group A [300.00 (270.00, 364.00)] minutes was shorter than that of group B [330.00 (300.00, 360.00)] minutes, p = 0.037. In addition, A set of postoperative hospital stay [12.00 (10.00, 15.00)] days shorter than group B [15.00 (12.00, 19.50)] days, p < 0.001. No PPH occurred in Group A, while 8 patients in Group B had PPH (7 cases of gastroduodenal artery hemorrhage and 1 case of proper hepatic artery hemorrhage), p = 0.019. The new technique of wrapping the hepatic hilar artery through the LTH can effectively reduce the occurrence of PPH after LPD.

INTRODUCTION: Pancreatoduodenectomy (PD) for pancreatic adenocarcinoma (PDAC) presents a significant challenge owing to its aggressive nature. Traditionally performed as open surgery, the advent of minimally invasive surgery (MIS) including laparoscopic and robotic techniques, offers a potential alternative. This study assessed the use and outcomes of MIS and open PD for PDAC treatment. METHODS: We analyzed ACS-NSQIP data (2015-2021) using regression models to compare patient outcomes across open PD, MIS PD, and conversions from MIS to open (MIS-O). RESULTS: Of 19,812 PDAC patients, 1,293 (6.53%) underwent MIS, 18,116 (91.44%) underwent open PD, and 403 (2.03%) underwent MIS converted to open PD (MIS-O). The MIS rate increased from 6.1% to 9.2%. Black patients had a higher MIS-O rate (RR, 1.55; p = 0.025). Open PD was associated with more severe conditions (ASA ≥ III, malnutrition) and prior radiation therapy. MIS patients more often had neoadjuvant chemotherapy. Complex procedures, such as vein resection, favored open PD. Need for arterial resection was associated with MIS-O (RR, 2.11; p = 0.012), and operative time was significantly associated with MIS (OR: 4.32, 95% CI: 3.43-5.43, p-value: < 0.001) No differences in the overall morbidity or 30-day mortality were observed. MIS led to shorter stays but higher risks of reoperation and pulmonary embolism. MIS-O increased the delayed gastric emptying rate (RR, 1.79; p < 0.001). CONCLUSION: During 2015-2021, an increasing number of patients with PDAC are undergoing MIS PD. Morbidity and mortality did not differ between open and MIS PD. MIS was performed more frequently in patients with better nutritional status and lower ASA, or when vascular resection was not anticipated. In well selected patients, short-term outcomes of MIS and open PD seem similar.

PURPOSE: To reduce perioperative risks among patients with a preoperative diabetes mellitus (DM) a total pancreatectomy (TP) might be a alternative to pancreatoduodenectomy (PD). This study aimed to compare the postoperative quality of life (QoL) of patients with preoperative DM undergoing PD or TP. METHODS: A single-centre retrospective study was conducted, all consecutive patients with preoperative DM undergoing PD or TP between 2011 and 2023 were identified in a prospective database. The primary endpoint was QoL, prospectively assessed using EORTC QLQ-C30 questionnaires at 3, 6, and 12 months after surgery and then annually until death. Secondary endpoints were morbidity and mortality. RESULTS: Seventy-one patients were included, 17 after TP and 54 after PD. Insulin-dependent DM occurred in 21 (39%) of the PD patients. QoL was worse after TP, especially in terms of physical functioning (-31.7 points; 95% CI: -50.0 to -13.3; P < 0.001), role functioning (-41.3 points; 95% CI: -61.3 to -21.3; P < 0.001), emotional functioning (-27.5 points; 95% CI: -50.4 to -4.6; P = 0.019), fatigue symptoms (20 points; 95% CI: 2.7 to 37.4; P = 0.024) and pain symptoms (30.2 points; 95% CI: 4.1 to 56.3; P = 0.024). The rates of postoperative major complications (29% vs. 35%; P = 0.853) and mortality (11% vs. 7%; P = 0.857) were similar between TP and PD. CONCLUSION: Postoperative morbidity and mortality were comparable between PD and TP, however QoL is significantly lower after TP. Importantly, patients with preoperative DM have a 60% chance of remaining noninsulin-dependent after PD.

BACKGROUND: The connection between early postoperative fever and clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy remains unclear. This study aimed to investigate this association and assess the predictive value of early postoperative fever for CR-POPF. METHODS: This retrospective observational study included adult patients who underwent pancreaticoduodenectomy at a tertiary teaching hospital between 2007 and 2019. Patients were categorized into those with early postoperative fever (≥ 38 °C in the first 48 h after surgery) and those without early postoperative fever groups. Weighted logistic regression analysis using stabilized inverse probability of treatment weighting (sIPTW) and multivariable logistic analysis were performed. The c-statistics of the receiver operating characteristic curves were calculated to evaluate the impact on the predictive power of adding early postoperative fever to previously identified predictors of CR-POPF. RESULTS: Of the 1997 patients analyzed, 909 (45.1%) developed early postoperative fever. The overall incidence of CR-POPF among all the patients was 14.3%, with an incidence of 19.5% in the early postoperative fever group and 9.9% in the group without early postoperative fever. Early postoperative fever was significantly associated with a higher risk of CR-POPF after sIPTW (adjusted odds ratio [OR], 1.73; 95% confidence interval [CI], 1.34-2.22; P < 0.001) and multivariable logistic regression analysis (adjusted OR, 1.88; 95% CI, 1.42-2.49; P < 0.001). The c-statistics for the models with and without early postoperative fever were 0.76 (95% CI, 0.73-0.79) and 0.75 (95% CI, 0.72-0.78), respectively, showing a significant difference between the two (difference, 0.02; 95% CI, 0.00-0.03; DeLong's test, P = 0.005). CONCLUSIONS: Early postoperative fever is a significant but not highly discriminative predictor of CR-POPF after pancreaticoduodenectomy. However, its widespread occurrence limits its applicability as a predictive marker.

OBJECTIVE: Achieving textbook outcome (TO) implies a smooth recovery post-operation without specified composite complications. This study aimed to evaluate TO in laparoscopic pancreaticoduodenectomy (LPD) and identify independent risk factors associated with achieving TO. METHODS: We conducted a retrospective analysis of data from a randomized controlled trial on LPD at West China Hospital (ChiCTR1900026653). Patients were categorized into the TO and non-TO groups. Perioperative variables were compared between these groups. Multivariate logistic regression was utilized to identify the risk factors. RESULTS: A total of 200 consecutive patients undergoing LPD were included in this study. TO was achieved in 82.5% (n = 165) of the patients. Female patients (OR: 2.877, 95% CI: 1.219-6.790; P = 0.016) and those with a hard pancreatic texture (OR: 2.435, 95% CI: 1.018-5.827; P = 0.046) were associated with an increased likelihood of achieving TO. CONCLUSIONS: TO can be achieved in more than 80% of patients in a high-volume LPD center. Independent risk factors associated with achieving TO included gender (male) and pancreatic texture (soft).

Background: Celiac axis stenosis can potentially lead to insufficient blood supply to vital organs, such as the liver, spleen, pancreas, and stomach. This condition result in the development of collateral circulation between the superior mesenteric artery and the hepatic artery. However, these collateral circulations are often disrupted during pancreaticoduodenectomy (PD), which may increase the risk of postoperative complications. Methods: A retrospective analysis was conducted on patients who underwent laparoscopic pancreaticoduodenectomy (LPD) from April 2015 to April 2023. Celiac trunk stenosis is classified according to the degree of stenosis: no stenosis (<30%), grade A (30%-<50%), grade B (50%-≤80%), and grade C (>80%). The incidence of postoperative complications was evaluated, and both univariate and multivariate risk analyses were conducted. Results: A total of 997 patients were included in the study, with mild celiac axis stenosis present in 23 (2.3%) patients, moderate stenosis in 18 (1.8%) patients, and severe stenosis in 10 (1.0%) patients. Independent risk factors for the development of bile leakage, as identified by both univariate and multivariate analyses, included body mass index (BMI) (HR = 1.108, 95% CI = 1.008-1.218, P = .033), intra-abdominal infection (HR = 2.607, 95% CI = 1.308-5.196, P = .006), postoperative hemorrhage (HR = 4.510, 95% CI = 2.048-9.930, P = <0.001), and celiac axis stenosis (50%-≤80%, HR = 4.235, 95% CI = 1.153-15.558, P = .030), and (>80%, HR = 4.728, 95% CI = .882-25.341, P = .047). Celiac axis stenosis, however, was not determined to be an independent risk factor for pancreatic fistula (P > 0.05). Additionally, the presence of an aberrant hepatic artery did not significantly increase the risk of postoperative complications when compared with celiac axis stenosis alone. Conclusion: Severe celiac axis stenosis is an independent risk factor for postoperative bile leakage following LPD.

BACKGROUND: Despite 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. METHODS: This 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. CONCLUSION: This 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 REGISTRATION: ClinicaTrials.gov number, NCT06123169 (Registration Date 08-11-2023); EudraCT number 2021-006991-18; EUCT Number: 2024-515181-14-00.

PURPOSE: To determine the causes of benign hepaticojejunostomy strictures (BHSs) after pancreaticoduodenectomy (PD) and the outcome of endoscopic retrograde cholangiography (ERC) treatment for BHSs. METHODS: A total of 175 patients who underwent PD between January 2013 and December 2020 and who were followed up for at least 1 year were included. Preoperative data, operative outcomes, and postoperative courses were compared between the BHS group and the group of patients who did not develop stenosis during follow-up (non-BHS group). The course of treatment in the BHS group was also examined. RESULTS: BHS occurred in 13 of 175 patients (7.4%). Multivariate analysis of the BHS and non-BHS groups revealed that male sex (OR; 3.753, 95% CI; 1.029-18.003, P = 0.0448) and a preoperative bile duct diameter less than 8.8 mm (OR; 7.51, 95% CI; 1.75-52.40, P = 0.0053) were independent risk factors for the development of BHS. In the BHS group, all patients underwent ERC using enteroscopy. The success rate of the ERC approach to the bile duct was 92.3%. Plastic stents were inserted in 6 patients, and metallic stents were inserted in 3 patients. The median observation period since the last ERC was 17.9 months, and there was no recurrence of stenosis in any of the 13 patients. CONCLUSIONS: Patients with narrow bile ducts are at greater risk of BHS after PD. Recently, BHS after PD has been treated with ERC-related procedures, which may reduce the burden on patients.

BACKGROUND: Pancreatic head cancer patients who undergo pancreatoduodenectomy (PD) often experience disease recurrence, frequently associated with a positive margin status (R1). Total mesopancreas excision (TMpE) has emerged as a potential approach to increase surgical radicality and minimize locoregional recurrence. However, its effectiveness and safety remain under evaluation. METHODS: We conducted a systematic review and meta-analysis to synthesize current evidence on TMpE outcomes. A systematic search of MEDLINE, EMBASE, Cochrane, and Web of Science databases was conducted up to March 2024 to identify studies comparing TMpE with standard pancreatoduodenectomy (sPD). The risk ratio (RR) or mean difference (MD) was pooled using a random effects model. RESULTS: From 452 studies identified, 9 studies with a total of 738 patients were included, with 361 (49%) undergoing TMpE. TMpE significantly improved the R0 resection rate (RR 1.24; 95% CI 1.11-1.38; P < 0.05), reduced blood loss (MD -143.70 ml; 95% CI -247.92, -39.49; P < 0.05), and increased lymph node harvest (MD 7.27 nodes; 95% CI 4.81, 9.73; P < 0.05). No significant differences were observed in hospital stay, postoperative complications, or mortality between TMpE and sPD. TMpE also significantly reduced overall recurrence (RR 0.53; 95% CI 0.35-0.81; P < 0.05) and local recurrence (RR 0.39; 95% CI 0.24-0.63; P < 0.05). Additionally, the risk of pancreatic fistula was lower in the TMpE group (RR 0.66; 95% CI 0.52-0.85; P < 0.05). CONCLUSION: Total mesopancreas excision significantly increases the R0 resection rate and reduces locoregional recurrence while maintaining an acceptable safety profile when compared with standard pancreatoduodenectomy. Further prospective randomized studies are warranted to determine the optimal surgical approach for total mesopancreatic resection.

Pancreatoduodenectomy is a complex surgical procedure with a high rate of morbidity, of which surgical-site infections (SSIs) make a large portion. Reduction of SSI rates is critical to decrease hospital lengths of stay, readmissions, delays in adjuvant therapies, and financial health care burden. Current clinical guidelines recommend the administration of cefoxitin as surgical prophylaxis prior to pancreatoduodenectomy. In April 2023, a randomized controlled trial was published in JAMA which showed that piperacillin-tazobactam as perioperative surgical prophylaxis prior to pancreatoduodenectomy decreased 30 day SSI rates (primary outcome), clinically relevant postoperative pancreatic fistula, postoperative sepsis, and Clostridium difficile infection rates.

Intraoperative hypotension (IOH) is a common issue associated with acute kidney injury, myocardial injury, stroke, and death. IOH may be avoided with the incorporation of newer advanced hemodynamic monitoring technologies. This case study examines the use of advanced hemodynamic monitoring with an early warning system for the intraoperative hemodynamic management of a patient presenting for pancreaticoduodenectomy. Incorporating the hypotension prediction index and other hemodynamic parameters to anticipate impending hypotension and treat potential causative factors is an emerging technological advancement. Understanding and embracing the potential for new advanced hemodynamic technology to reduce intraoperative hypotension's severity, duration, and occurrence is key to reducing negative patient outcomes.

BACKGROUND: Meta-analysis of 10 randomized prospective trials demonstrated a higher risk of postoperative bleeding from pancreaticogastrostomy (PG) compared with pancreatojejunostomy following pancreatoduodenectomy (PD). This study evaluated the incidence, risk factors, and treatment of anastomotic bleeding from invaginated PG. METHODS: We retrospectively evaluated all consecutive PDs performed between April 1, 2011 and December 31, 2022 using invaginated PG by the double purse-string technique. Multivariate analysis identified risk factors for anastomotic PG bleeding. RESULTS: During the study, 695 consecutive patients with a median age of 66 years underwent PD; the majority was performed for ductal pancreatic adenocarcinomas. Simultaneous vascular resections were performed in 328 patients. Postoperative mortality was 4.1%. Bleeding from PG occurred in 33(4.6%) patients at a median interval of 5 days (range, 1-14) from surgery, leading to reoperation in 21(63%). PG bleeding-related mortality was 9.0%. Multivariate analyses identified a soft pancreatic texture and Wirsung duct > 3 or ≤ 3 mm (Class C and D, respectively, of the ISGPS) (odds ratio [OR]: 2.17, 95% confidence interval [95% CI]: 1.38-3.44; P = 0.0009) and wrapping of the invaginated pancreas (OR: 0.37, 95% CI: 0.17-0.84; P = 0.01) as independent risk factors for PG bleeding. CONCLUSIONS: In a large volume setting, anastomotic bleeding from invaginated PG occurred in ~ 5% of patients and was associated with soft pancreatic parenchyma and small wirsung duct. The reduced rate of PG bleeding observed with wrapping of the invaginated pancreatic stump warrants further evaluation in a prospective randomized study.

OBJECTIVE: We would like to investigate the prognostic utility of the previously described factors and offer a new parameter called neutrophil-to-C-reactive protein ratio (NCR) as a predictor of post-operative complications of pancreas cancer. METHODS: 92 patients underwent pancreaticoduodenectomy for the pancreatic head tumor were enrolled in this study. Receiver operating curve analysis was performed to detect the cutoff values, and logistic regression analyses were performed to identify the independent risk factors of complications. RESULTS: In univariate analysis, complications were observed in lymphocyte-to-C-reactive protein ratio levels below 0.06 (Odds Ratio [OR]: 3.92, 95% confidence interval [CI] = 1.08-14.21, p = 0.037). In multivariate analysis, albumin < 3.6 (OR: 3.25, 95% CI: 1.16-9.06, p = 0.024) and NCR < 0.28 (OR: 2.81, 95 % CI: 1.07-7.63, p = 0.042) were the independent and significant predictors of the overall survival. DISCUSSION: Quantification of preoperative NCR and albumin may help surgeons to settle an effective perioperative management, take extra caution, and be aware of post-operative complications of pancreatic cancer patients.
OBJETIVO: Se investigó la proporción de neutrófilos a proteína C reactiva (NCR) como predictor de complicaciones posoperatorias del cáncer de páncreas. MATERIAL Y MÉTODOS: 92 pacientes fueron sometidos a pancreaticoduodenectomía (PD) por el tumor de la cabeza del páncreas incluidos en este estudio. Se realizaron análisis de curva operativa del receptor (ROC) y análisis de regresión logística para detectar los valores de corte y los factores de riesgo independientes de complicaciones. RESULTADOS: En análisis univariado; se observaron complicaciones en niveles de LCR por debajo de 0,06 (OR: 3.92, IC 95%: 1.08-14.21, p = 0.037). En análisis multivariado; albúmina < 3.6 (OR: 3.25, IC 95 %: 1.16-9.06, p = 0.024), NCR < 0.28 (OR: 2.81, IC 95 %: 1.07-7.63, p = 0.042) fueron los predictores independientes y significativos de la supervivencia. CONCLUSIÓN: La cuantificación de la NCR y la albúmina preoperatorias puede ayudar a los cirujanos a establecer un manejo perioperatorio efectivo, tomar precauciones adicionales y estar atentos a las complicaciones posoperatorias.

BACKGROUND: The advancement of laparoscopic technology has broadened the application of laparoscopic pancreaticoduodenectomy (LPD) for treating pancreatic head and ampullary tumors. Despite its benefits, postoperative pancreatic fistula (POPF) and postpancreatectomy hemorrhage (PPH) remain significant complications. Ligamentum teres hepatis wrapping around the gastroduodenal artery (GDA) stump show limitations in reducing POPF and PPH. METHODS: This study retrospectively analyzed patients undergoing LPD from January 2016 to October 2023, We compared the effectiveness of the two-parts wrapping (the ligamentum teres hepatis wrapping of the gastroduodenal artery stump and the omentum flap wrapping of the pancreatojejunal anastomosis) and ligamentum teres hepatis wrapping around the gastroduodenal artery (GDA) in reducing postoperative pancreatic fistula (POPF) and postpancreatectomy hemorrhage (PPH), using propensity score matching for the analysis. RESULTS: A total of 172 patients were analyzed, showing that the two-parts wrapping group significantly reduced the rates of overall and severe complications, POPF, and PPH compared to ligamentum teres hepatis wrapping around the GDA group. Specifically, the study found lower rates of grade B/C POPF and no instances of PPH in the two-parts wrapping group, alongside shorter postoperative hospital stays and drainage removal times. These benefits were particularly notable in patients with soft pancreatic textures and pancreatic duct diameters of < 3 mm. CONCLUSION: The two-parts wrapping technique significantly reduce the risks of POPF and PPH in LPD, offering a promising approach for patients with soft pancreas and pancreatic duct diameter of < 3 mm.

INTRODUCTION: The prevalence of overweight or obesity among patients undergoing pancreaticoduodenectomy is on the rise. The utilisation of robotic assistance has the potential to enhance the feasibility of performing minimally invasive pancreaticoduodenectomy in this particular group of patients who are at a higher risk. The objective of this meta-analysis is to assess the safety and effectiveness of robotic pancreaticoduodenectomy in individuals with overweight or obesity. METHODS AND ANALYSIS: This investigation will systematically search for randomised controlled trials (RCTs) and non-randomised comparative studies that compare robotic pancreaticoduodenectomy with open or laparoscopic pancreaticoduodenectomy in patients with overweight or obesity, using PubMed, Embase and the Cochrane Library databases. The methodological quality of studies will be evaluated using the Cochrane risk of bias tool for RCTs and the Newcastle-Ottawa Scale for observational studies. RevMan software (V.5.4.1) will be used for statistical analysis. The OR and weighted mean differences will be calculated separately for dichotomous and continuous data. The selection of a fixed-effects or random-effects model will depend on the level of heterogeneity observed among the included studies. ETHICS AND DISSEMINATION: This study will be conducted based on data in the published literature from publicly available databases. Therefore, ethics approval is not applicable. The results will be disseminated in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42023462321.

Since its first description in 1898, pancreaticoduodenectomy has constantly been improved, allowing increasingly more complex operations to be performed even with a minimally invasive approach: laparoscopic and, in recent years, robotic approach. In most cases, similarly to open surgery, parenchymal transection is performed after the creation of a retropancreatic tunnel to ensure adequate control of the mesenteric vessels before sectioning the parenchyma. Sometimes tunnelling can be very difficult even dangerous to achieve, due to conditions such as: vascular involvement by the neoplasm of superior mesenteric vein (SMV) or portal vein (PV); fibrosis secondary to acute pancreatitis (AP) or radiotherapy. In such conditions, it seems suitable to avoid tunnelling before parenchymal transection. We will describe how we perform the standard technique which we will call 'Tunnel First approach' (TF) and then our new 'Parenchyma Transection-First' (PTF) approach in its two variants: 'bottom to top' and 'top to bottom'.

PURPOSE: Laparoscopic pancreatoduodenectomy (LPD) has emerged as an alternative to open technique in treating periampullary tumors. However, the safety and efficacy of LPD compared to open pancreatoduodenectomy (OPD) remain unclear. Thus, we conducted an updated meta-analysis to evaluate the efficacy and safety of LPD versus OPD in patients with periampullary tumors, with a particular focus on the pancreatic ductal adenocarcinoma patient subgroup. METHODS: According to PRISMA guidelines, we searched PubMed, Embase, and Cochrane Library in December 2023 for randomized controlled trials (RCTs) that directly compare LPD versus OPD in patients with periampullary tumors. Endpoints and sensitive analysis were conducted for short-term endpoints. All statistical analysis was performed using R software version 4.3.1 with a random-effects model. RESULTS: Five RCTs yielding 1018 patients with periampullary tumors were included, of whom 511 (50.2%) were randomized to the LPD group. Total follow-up time was 90 days. LPD was associated with a longer operation time (MD 66.75; 95% CI 26.59 to 106.92; p = 0.001; I2 = 87%; Fig. 1A), lower intraoperative blood loss (MD - 124.05; 95% CI - 178.56 to - 69.53; p < 0.001; I2 = 86%; Fig. 1B), and shorter length of stay (MD - 1.37; 95% IC - 2.31 to - 0.43; p = 0.004; I2 = 14%; Fig. 1C) as compared with OPD. In terms of 90-day mortality rates and number of lymph nodes yield, no significant differences were found between both groups. CONCLUSION: Our meta-analysis of RCTs suggests that LPD is an effective and safe alternative for patients with periampullary tumors, with lower intraoperative blood loss and shorter length of stay.
