[PMID: 38943154 PMCID: PMC11214213 DOI: 10.1186/s12957-024-03451-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Accepted: 06/16/2024] [Indexed: 07/01/2024] Open
Abstract
BACKGROUND Existing research on chyle leak (CL) after pancreatic surgery is mostly focused on pancreaticoduodenectomy and lacks investigation on total pancreatectomy (TP). This study aimed to explore potential risk factors of CL and develop a predictive model for patients with pancreatic tumor undergoing TP. METHODS This retrospective study enrolled 90 consecutive patients undergoing TP from January 2015 to December 2023 at Peking Union Medical College Hospital. According to the inclusion criteria, 79 patients were finally included in the following analysis. The LASSO regression and multivariate logistic regression analysis were performed to identify risk factors associated with CL and construct a predictive nomogram. Then, the ROC analysis, calibration curve, decision curve analysis (DCA), and clinical impact curve (CIC) were performed to assess its discrimination, accuracy, and efficacy. Due to the small sample size, we adopted the bootstrap resampling method with 500 repetitions for validation. Lastly, we plotted and analyzed the trend of postoperative drainage volume in CL patients. RESULTS We revealed that venous resection (OR = 4.352, 95%CI 1.404-14.04, P = 0.011) was an independent risk factor for CL after TP. Prolonged operation time (OR = 1.473, 95%CI 1.015-2.237, P = 0.052) was also associated with an increased incidence of CL. We included these two factors in our prediction model. The area under the curve (AUC) was 0.752 (95%CI 0.622-0.874) after bootstrap. The calibration curve, DCA and CIC showed great accuracy and clinical benefit of our nomogram. In patients with CL, the mean drainage volume was significantly higher in venous resection group and grade B CL group. CONCLUSION Venous resection was an independent risk factor for chyle leak after TP. Patients undergoing vascular resection during TP should be alert for the occurrence of CL after surgery. We then constructed a nomogram consisted of venous resection and operation time to predict the odds of CL in patients undergoing TP.

Ferumoxtran-10-enhanced MRI for pre-operative metastatic lymph node detection in pancreatic, duodenal, or periampullary adenocarcinoma. Eur Radiol 2024:10.1007/s00330-024-10838-w. [PMID: 38907886 DOI: 10.1007/s00330-024-10838-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 04/18/2024] [Accepted: 04/26/2024] [Indexed: 06/24/2024]
Abstract
OBJECTIVES To assess 3-Tesla (3-T) ultra-small superparamagnetic iron oxide (USPIO)-enhanced MRI in detecting lymph node (LN) metastases for resectable adenocarcinomas of the pancreas, duodenum, or periampullary region in a node-to-node validation against histopathology. METHODS Twenty-seven consecutive patients with a resectable pancreatic, duodenal, or periampullary adenocarcinoma were enrolled in this prospective single expert centre study. Ferumoxtran-10-enhanced 3-T MRI was performed pre-surgery. LNs found on MRI were scored for suspicion of metastasis by two expert radiologists using a dedicated scoring system. Node-to-node matching from in vivo MRI to histopathology was performed using a post-operative ex vivo 7-T MRI of the resection specimen. Sensitivity and specificity were calculated using crosstabs. RESULTS Eighteen out of 27 patients (median age 65 years, 11 men) were included in the final analysis (pre-surgery withdrawal n = 4, not resected because of unexpected metastases peroperatively n = 2, and excluded because of inadequate contrast-agent uptake n = 3). On MRI 453 LNs with a median size of 4.0 mm were detected, of which 58 (13%) were classified as suspicious. At histopathology 385 LNs with a median size of 5.0 mm were found, of which 45 (12%) were metastatic. For 55 LNs node-to-node matching was possible. Analysis of these 55 matched LNs, resulted in a sensitivity and specificity of 83% (95% CI: 36-100%) and 92% (95% CI: 80-98%), respectively. CONCLUSION USPIO-enhanced MRI is a promising technique to preoperatively detect and localise LN metastases in patients with pancreatic, duodenal, or periampullary adenocarcinoma. CLINICAL RELEVANCE STATEMENT Detection of (distant) LN metastases with USPIO-enhanced MRI could be used to determine a personalised treatment strategy that could involve neoadjuvant or palliative chemotherapy, guided resection of distant LNs, or targeted radiotherapy. REGISTRATION The study was registered on clinicaltrials.gov NCT04311047. https://clinicaltrials.gov/ct2/show/NCT04311047?term=lymph+node&cond=Pancreatic+Cancer&cntry=NL&draw=2&rank=1 . KEY POINTS LN metastases of pancreatic, duodenal, or periampullary adenocarcinoma cannot be reliably detected with current imaging. This technique detected LN metastases with a sensitivity and specificity of 83% and 92%, respectively. MRI with ferumoxtran-10 is a promising technique to improve preoperative staging in these cancers.

The impact of lymphangiograpy on chyle leakage treatment duration after pancreatic surgery. Surg Today 2024; 54:651-657. [PMID: 38062229 DOI: 10.1007/s00595-023-02777-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 10/10/2023] [Indexed: 05/21/2024]
Abstract
PURPOSE Chyle leakage (CL) is a common complication in pancreatic surgery. Lymphangiography is a therapeutic option for CL in cases of conservative treatment failure. This study investigated the effect of lymphangiography on the healing time of CL. METHODS We retrospectively evaluated 283 patients who underwent pancreatic resection between January 2016 and June 2022. The risk factors for CL and the treatment period were evaluated according to whether or not lymphangiography was performed. RESULTS Of the 29 patients (10.2%) that had CL, lymphangiography was performed in 6. Malignant disease, the number of harvested lymph nodes, and drain fluid volume on postoperative day 2 were identified as independent risk factors for CL. Lymphangiography was associated with the cumulative healing rate of CL, and patients who underwent lymphangiography had a significantly shorter treatment period. No lymphangiography-related adverse events were observed. CONCLUSION Lymphangiography is a feasible and safe treatment option for CL. The CL treatment period after pancreatic surgery was significantly shorter in patients who underwent lymphangiography than in those who did not. Our results suggest that lymphangiography may contribute to early improvement of persistent CL.

Abstract
BACKGROUND The role of the robotic approach for pancreaticoduodenectomy has not been well established with robust data. This study aimed to reappraise feasibility and justification of robotic pancreaticoduodenectomy (RPD) over time. METHODS A total of 500 patients undergoing RPD were enrolled and divided into early (first 250 patients) and late (last 250 patients) groups for a comparative study. RESULTS The conversion rate was 8.8% overall and was significantly lower in the late group (5.6% vs. 12.0%; p = .012). The overall median intraoperative blood loss was 130 mL. Radicality of resection was similar between early and late groups. The overall surgical mortality after RPD was 1.3%. The overall surgical morbidity and major complication was 44.1% and 13.2%, respectively, and similar between early and late groups. Chyle leakage was the most common complication after RPD (25.0%), followed by postoperative pancreatic fistula (POPF). The POPF rate was 8.6% overall, with 5.9% in the early group and 11.0% in the late group, p = .051. The overall delayed gastric emptying rate was 3.5%. The late group had better survival outcomes than those of the early group after RPD for ampullary adenocarcinoma (p = .027) but not for pancreatic head adenocarcinoma. CONCLUSIONS Reappraisal of this study has confirmed that RPD is not only technically feasible without increasing surgical risks but also oncologically justified without compromising survival outcomes for both pancreatic head and other periampullary cancers over time. Moreover, RPD is associated with the benefits of low surgical mortality, blood loss, and delayed gastric emptying.

Abstract
BACKGROUND To define the incidence and risk factors of chyle leak (CL) after radical nephrectomy and thrombectomy and to determine the impact of chyle leak on oncological outcomes. PATIENTS AND METHODS A total of 445 patients who underwent radical nephrectomy and thrombectomy between January 2014 and January 2023 were included. CL is defined as the drainage of chyle with a triglyceride level greater than 110 mg/dL after oral intake or enteral nutrition. Multivariate logistic regression analysis was performed to identify the risk factors of postoperative (CL). The Kaplan-Meier curves were used to compare overall survival and cancer-specific survival. RESULTS 44 patients (9.9%) were diagnosed as (CL). All patients developed CL within 6 days after the operation with a median time of 3 days. In multivariate logistic regression analysis, Mayo grade and side were independent patient-related risk factors. In addition, operation approach, operation time, and number of lymph nodes harvested were independent surgery-related risk factors. Between the CL group and the non-CL group, neither overall survival nor cancer-specific survival showed statistical differences. CONCLUSION Based on this retrospective study of renal cell carcinoma and tumor thrombus patients in our center, we found that the risk factors were Mayo grade, side, operation approach, operation time, and number of lymph nodes harvested, and the occurrence of CL significantly prolonged hospital stay, but had no effect on long-term oncological outcomes.

Abstract
Chylous ascites is an uncommon condition of accumulation of milky fluid rich in lymph and chylomicrons in the peritoneal cavity. Post-surgical complications following dissection near the base of the mesentery, retroperitoneum, or near the cisterna chyli, malignancies (e.g., pancreatic adenocarcinomas, lymphoma, gastric carcinoma), cirrhosis, and trauma are the prime causes of chylous ascites. Here we report a rare case of chylous ascites following clearance of isolated paraaortic nodal recurrence in a 28-year-old female with dysgerminoma of ovary. The patient developed chylous ascites on the fifth day following surgery, which was confirmed by an increased drain fluid triglyceride level. She was managed conservatively with dietary modification including a high-protein and carbohydrate but low-fat-based diet mainly containing medium-chain fatty acids. Subsequently, she recovered from chylous ascites on the sixteenth day, completed second line chemotherapy, and is now doing well.

Abstract
Background Post-operative chylous leakage (CL) is the pathologic leakage of chylomicron fluid after surgery. This retrospective study was performed to evaluate a uniform oral nutrition management strategy on the post-operative CL. Methods We retrospectively reviewed patients who developed post-operative CL and received consultation from a clinical nutritionist in seven departments of the Second Affiliated Hospital of Dalian Medical University from May 2020 to April 2022. We designed the oral nutrition intervention program which mainly standardized the type and amount of foods contained in the medium-chain triglyceride (MCT) diet. The influencing factors of curative efficacy were analyzed. Finally, binary logistic regression analysis was conducted to observe the relationship between curative efficacy and potentially predictive variables, including post-operative albumin, post-operative hemoglobin, surgical procedure, and drainage volume at consultation. Results Sixty-three patients with post-operative CL were included in this analysis. Of this number, 58 patients were cured successfully without other treatments. Three patients had a significantly prolonged recovery period, and the remaining two cases were treated by reoperation therapy. The leakage volume at the initiation of enteral intervention had no statistically significant difference in seven surgical departments and surgical sites (left, right, median, and bilateral). The length of stay (LOS) of patients with CL after the intervention was not significantly increased in cardiac, hepatobiliary, gastrointestinal, and urological surgeries. Patients with CL had longer LOS than those without CL in gynecology (P=0.044) and thyroid surgery departments (P=0.008). Each unit increase in post-operative hemoglobin would increase the probability of an effective outcome by 8%, which was statistically significant (P = 0.037). Conclusion In treating patients with post-operative CL, we recommend the MCT diet and EN as the first option, rather than fasting, parenteral nutrition (PN), or octreotide.

Abstract
OBJECTIVE The aim of this study was to assess the clinical impact and risk factors of chyle leak (CL). BACKGROUND In 2017, the International Study Group for Pancreatic Surgery (ISGPS) published the consensus definition of CL. Multicenter series validating this definition are lacking and previous studies investigating risk factors have used different definitions and showed heterogeneous results. METHODS This observational cohort study included all consecutive patients after pancreatoduodenectomy in all 19 centers in the mandatory nationwide Dutch Pancreatic Cancer Audit (2017-2019). The primary endpoint was CL (ISGPS grade B/C). Multivariable logistic regression analyses were performed. RESULTS Overall, 2159 patients after pancreatoduodenectomy were included. The rate of CL was 7.0% (n=152), including 6.9% (n=150) grade B and 0.1% (n=2) grade C. CL was independently associated with a prolonged hospital stay [odds ratio (OR)=2.84, 95% confidence interval (CI): 1.85-4.36, P <0.001] but not with mortality (OR=0.3, 95% CI: 0.0-2.3, P =0.244). In multivariable analyses, independent predictors for CL were vascular resection (OR=2.1, 95% CI: 1.4-3.2, P <0.001) and open surgery (OR=3.5, 95% CI: 1.7-7.2, P =0.001). The number of resected lymph nodes and aortocaval lymph node sampling were not identified as predictors in multivariable analysis. CONCLUSIONS In this nationwide analysis, the rate of ISGPS grade B/C CL after pancreatoduodenectomy was 7.0%. Although CL is associated with a prolonged hospital stay, the clinical impact is relatively minor in the vast majority (>98%) of patients. Vascular resection and open surgery are predictors of CL.

Eur J Surg Oncol 2021; 48:707-717. [PMID: 34887165 DOI: 10.1016/j.ejso.2021.11.136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 10/25/2021] [Accepted: 11/29/2021] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND Chyle leak (CL) is a clinically relevant complication after pancreatectomy. Its incidence and the associated risk factors are ill defined, and various treatments options have been described. There is no consensus, however, regarding optimal management. The present study aims to systematically review the literature on CL after pancreatectomy. METHODS A systematic review from PubMed, Scopus and Embase database was performed. Studies using a clear definition for CL and published from January 2000 to January 2021 were included. The PRISMA guidelines were followed during all stages of this systematic review. The MINORS score was used to assess methodological quality. RESULTS Literature search found 361 reports, 99 of which were duplicates. The titles and abstracts of 262 articles were finally screened. The references from the remaining 181 articles were manually assessed. After the exclusions, 43 articles were thoroughly assessed. A total of 23 articles were ultimately included for this review. The number of patients varied from 54 to 3532. Incidence of post pancreatectomy CL varied from 1.3% to 22.1%. Main risk factors were the extent of the surgery and early oral or enteral feeding. CL dried up spontaneously or after conservative management within 14 days in 53% to 100% of the cases. CONCLUSIONS The extent of surgery is the most common predictor of risk of CL. Conservative treatment has been shown to be effective in most cases and can be considered the treatment of choice. We propose a management algorithm based on the current available evidence.

[PMID: 34417025 DOI: 10.1016/j.surg.2021.07.021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2021] [Revised: 06/28/2021] [Accepted: 07/15/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND The incidence of and risk factors for chyle leak, as defined by the 2017 International Study Group on Pancreatic Surgery, remain unknown. METHODS MEDLINE, EMBASE, and Scopus were systematically searched for studies of patients undergoing pancreatectomy that reported chyle leak according to the 2017 International Study Group on Pancreatic Surgery definition. The primary outcomes were the incidence of overall and clinically relevant chyle leak. A random-effects pairwise meta-analysis was used to calculate the incidence of chyle leak. RESULTS Thirty-five studies including 7,083 patients were included in the meta-analysis. The weighted incidence of overall chyle leak was 6.8% (95% confidence interval 5.6-8.2), and clinically relevant chyle leak was 5.5% (95% confidence interval 3.8-7.7). Pancreaticoduodenectomy, total pancreatectomy, and distal pancreatectomy were associated with a CL incidence of 7.3%, 4.3%, and 5.8%, respectively. Fourteen individual risk factors for chyle leak were identified from included studies. Younger age, low prognostic nutritional index, para-aortic node manipulation, lymphatic involvement, and post-pancreatectomy pancreatitis were significantly associated with chyle leak, all from individual studies. CONCLUSION The incidence of overall chyle leak and clinically relevant chyle leak after pancreatic surgery, as defined by the 2017 International Study Group on Pancreatic Surgery, is 6.8% and 5.5%, respectively. Several risk factors for chyle leak were identified in the present review; however, larger high-quality studies are needed to more accurately define these risks.

Fukui T, Noda H, Watanabe F, Kato T, Endo Y, Aizawa H, Kakizawa N, Iseki M, Rikiyama T. Drain output volume after pancreaticoduodenectomy is a useful warning sign for postoperative complications. BMC Surg 2021; 21:279. [PMID: 34082725 PMCID: PMC8176603 DOI: 10.1186/s12893-021-01285-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 06/01/2021] [Indexed: 01/04/2023] Open
Abstract
Introduction The drain output volume (DOV) after pancreaticoduodenectomy (PD) is an easily assessable indicator in clinical settings. We explored the utility of the DOV as a possible warning sign of complications after PD. Methods A total of 404 patients undergoing PD were considered for inclusion. The predictability of the DOV for overall morbidity, major complications, intraabdominal infection (IAI), clinically relevant (CR) postoperative pancreatic fistula (POPF), CR delayed gastric emptying (DGE), CR chyle leak (CL), and CR post-pancreatectomy hemorrhaging (PPH) was evaluated. Results One hundred (24.8%) patients developed major complications, and 131 (32.4%) developed IAI. Regarding CR post-pancreatectomy complications, 75 (18.6%) patients developed CR-POPF, 23 (5.7%) developed CR-DGE, 20 (5.0%) developed CR-CL, and 28 (6.9%) developed CR-PPH. The median DOV on postoperative day (POD) 1 and POD 3 was 266 and 234.5 ml, respectively. A low DOV on POD 1 was an independent predictor of CR-POPF, and a high DOV on POD 3 was an independent predictor of CR-CL. A receiver operating characteristics (ROC) analysis revealed that the DOV on POD 1 had a negative predictive value (area under the curve [AUC] 0.655, sensitivity 65.0%, specificity 65.3%, 95% confidence interval [CI]: 0.587–0.724), with a calculated optimal cut-off value of 227 ml. An ROC analysis also revealed that the DOV on POD 3 had a positive predictive value (AUC 0.753, sensitivity 70.1%, specificity 75.0%, 95% CI: 0.651–0.856), with a calculated optimal cut-off value of 332 ml. Conclusion A low DOV on POD 1 might be a postoperative warning sign for CR-POPF, similar to high drain amylase (DA) on POD 1, high DA on POD 3, and high CRP on POD 3. When the DOV on POD 1 after PD was low, surgeons should evaluate the reasons of a low DOV. A high DOV on POD 3 was a postoperative warning sign CR-CL, and might require an appropriate management of protein loss.
