Central venous catheter insertion in the internal jugular vein (IJV) is frequently performed in acute care settings, facilitated by its easy availability and increased use of ultrasound in healthcare settings. Despite the increased safety profile and insertion convenience, it has complications. Herein, we aim to inform readers about the existing literature on the plethora of complications with potentially disastrous consequences for patients undergoing IJV cannulation.

OBJECTIVE
Prediction of lymph node metastasis (LNM) for intrahepatic cholangiocarcinoma (ICC) is critical for the treatment regimen and prognosis. We aim to develop and validate machine learning (ML)-based predictive models for LNM in patients with ICC.
METHODS
A total of 345 patients with clinicopathological characteristics confirmed ICC from Jan 2007 to Jan 2019 were enrolled. The predictors of LNM were identified by the least absolute shrinkage and selection operator (LASSO) and logistic analysis. The selected variables were used for developing prediction models for LNM by six ML algorithms, including Logistic regression (LR), Gradient boosting machine (GBM), Extreme gradient boosting (XGB), Random Forest (RF), Decision tree (DT), Multilayer perceptron (MLP). We applied 10-fold cross validation as internal validation and calculated the average of the areas under the receiver operating characteristic (ROC) curve to measure the performance of all models. A feature selection approach was applied to identify importance of predictors in each model. The heat map was used to investigate the correlation of features. Finally, we established a web calculator using the best-performing model.
RESULTS
In multivariate logistic regression analysis, factors including alcoholic liver disease (ALD), smoking, boundary, diameter, and white blood cell (WBC) were identified as independent predictors for LNM in patients with ICC. In internal validation, the average values of AUC of six models ranged from 0.820 to 0.908. The XGB model was identified as the best model, the average AUC was 0.908. Finally, we established a web calculator by XGB model, which was useful for clinicians to calculate the likelihood of LNM.
CONCLUSION
The proposed ML-based predicted models had a good performance to predict LNM of patients with ICC. XGB performed best. A web calculator based on the ML algorithm showed promise in assisting clinicians to predict LNM and developed individualized medical plans.

INTRODUCTION
Inadvertent thoracic duct injury is common during esophagectomy and may result in postoperative chylothorax. This study's objective is to investigate utility of patent-blue injection as a modality for intraoperative thoracic duct visualization.
METHODS
A prospective, single-arm, interventional study of patients undergoing minimally invasive esophagectomy was performed. Patients were injected with patent-blue dye into both groins prior to thoracic stage of surgery and assessed for duct visualization. Control group was formed by propensity score matching using retrospectively collected data regarding patients who underwent esophagectomy.
RESULTS
A total of 25 patients were included in analysis, compared to a control of 50 patients after matching. Thoracic duct was visualized in 60% of patients in the study group (15/25 patients). Significant differences were found between study and control groups(p<0.05) with regards to median operative time (422 vs. 285 minutes, respectively), overall complications (16% vs. 34%, respectively) and median postoperative length of stay (13.5 vs. 10 days, respectively). There was a difference in rate of chyle leak between study and control groups, however this was not significant (0% vs. 12%, respectively, p=0.17).
CONCLUSION
Patent-blue injection represents a simple method for thoracic duct visualization during minimally invasive esophagectomy which may improve surgical outcomes.

Review
BACKGROUND
Chylous leakage is a rare complication following esophagectomy; however, it can lead to mortality. We aimed to systematically evaluate the factors that may lead to increased chylous leakage after esophagectomy.
METHODS
Three databases (PubMed, Embase, and Cochrane Library) were systematically searched for all studies investigating the occurrence of chylous leakage after esophagectomy.
RESULTS
A total of 32 studies were identified, including 26 randomized controlled trials and 3 cohort and case-control studies, each. The overall incidence of chylous leakage was 4.7% (278/5,971 cases). Analysis of preoperative, intraoperative, and postoperative factors showed that most of the qualitative analysis results did not significantly increase the incidence of chylous leakage. In some quantitative analyses, the chylous leakage rate was significantly lower in the thoracic duct mass ligation group than in the conservative treatment group (relative risk [RR] = 0.33; 95% confidence interval [CI], 0.13-0.83; I = 0.0%; P = 0.327). Direct oral feeding significantly reduced chylous leakage compared with jejunostomy (RR = 0.06; 95% CI 0.01-0.33; I = 0.0%; P = 0.335). However, preoperative inspiratory muscle training (RR = 1.66; 95% CI, 0.21-12.33; I = 55.5%; P = 0.134), preoperative chemoradiotherapy (RR = 0.99; 95% CI, 0.55-1.80; I = 0.0%; P = 0.943), and robotic assistance (RR = 1.62; 95% CI, 0.92-2.86; I = 0.0%; P = 0.814) did not significantly reduce the incidence of chylous leakage.
CONCLUSIONS
Ligation of the thoracic duct and direct oral feeding can reduce the incidence of chylous leakage after esophagectomy in patients with esophageal cancer. Other contributing factors remain unclear and require validation in further high-quality studies.

BACKGROUND
Current management of axillosubclavian deep venous thrombosis (DVT) often uses thrombolysis for the DVT, prompt first rib removal, and occasional venoplasty or stenting. Our institution has increasingly used anticoagulation alone followed by interval first rib resection. We sought to analyze the effectiveness of this simplified technique.
METHODS
Between September 2012 and April 2021, 27 patients were identified within the institution's electronic medical record as having undergone first rib resection for upper extremity DVT. Seven of these patients had undergone preoperative thrombolysis before referral and were excluded. Among the remaining 20 patients, preoperative clinic charts were evaluated for age, venous segment involvement, contralateral limb involvement, presence of documented hypercoagulable state, duration of preoperative and postoperative anticoagulation, and postoperative outcomes.
RESULTS
Of the 20 patients (mean age, 26.2 years; 13 males) presenting with acute axillosubclavian DVT, all patients had right (n = 8) or left (n = 12) arm swelling. Five patients had extremity pain and four had extremity discoloration. Ten had axillosubclavian vein involvement, 9 had subclavian vein involvement, and 1 had axillary vein involvement. Two patients were on oral contraceptives and no patients had any other diagnosed hypercoagulable conditions. The mean duration of preoperative and postoperative anticoagulation was 3.2 ± 2.6 months and 2.1 ± 2.1 months, respectively. Nineteen patients underwent supraclavicular first rib resection and 1 patient underwent transaxillary resection. Twelve patients (60%) demonstrated complete DVT resolution by venous duplex examination during the postoperative period and 8 patients (40%) demonstrated partial recanalization/chronic DVT. Complications included one hemothorax and one thoracic duct injury. All 20 patients remain asymptomatic without arm swelling, with a mean follow-up of 55.1 ± 34.7 months.
CONCLUSIONS
Among patients presenting with acute axillosubclavian DVT, anticoagulation alone followed by interval first rib resection proved to be successful in providing symptomatic relief in the short to medium term. By eliminating the need for preoperative thrombolysis and postoperative venograms, this potentially cost-saving algorithm simplifies our management for acute venous thoracic outlet syndrome while maintaining good clinical outcomes. Because this study only analyzed our management algorithm's effectiveness in the short to medium term, the long-term effectiveness of this treatment will need to be demonstrated.

Chylothorax after cardiac surgery is a rare complication associated with severe morbidity and mortality. This report documents successful treatment with percutaneous thoracic duct embolization for chylothorax after total arch replacement. A 69-year-old man underwent replacement of the aortic arch to treat a ruptured aortic aneurysm. After surgery, the left thoracic drain discharged 2,000 to 3,000 mL serosanguineous fluid per day, even though the patient took nothing orally and was administered subcutaneous octreotide therapy. On postoperative day 9, percutaneous thoracic duct embolization was performed, and the drain could be removed. The chylothorax did not recur, and the patient was discharged on postoperative day 17.

For patients with hepatocellular carcinoma and cirrhosis, the rupture of thin lymphatic vessel walls leads to a profuse outflow of lymph fluid. Typically, chyloperitoneum tends to precede the development of chylothorax in patients with cancer. The present study describes the case of a male patient with hepatocellular carcinoma who developed chylothorax without chyloperitoneum. Computed tomography showed lymphatic system developmental abnormalities with a large volume of leaked lymph fluid. Multiple thoracic duct ligations (TDLs) failed, but a side-to-end lymphatic venous anastomosis (LVA) surgery resolved the symptoms. To the best of our knowledge, there are no reports of chylothorax occurrence after cirrhosis further complicated by congenital lymphatic abnormalities in the English-language literature. In conclusion, LVA could be appropriate to treat chylothorax when TDL is ineffective as a remedial or even prophylactic intervention.

INTRODUCTION
Chylothorax (CT) is a rare yet serious complication after esophagectomy. Identification of the thoracic duct (TD) during esophagectomy is challenging due to its anatomical variation. Real-time identification of TD may help to prevent its injury. Near infra-red imaging with Indocyanine green (ICG) is a novel technique that recently has been used to overcome this issue.
METHODS
Patients who underwent minimally invasive esophagectomy for esophageal cancer were divided into two groups with and without ICG. We injected ICG into bilateral superficial inguinal lymph nodes. Identification of TD and its injuries during the operation was evaluated and compared with the non-ICG group.
RESULTS
Eighteen patients received ICG, and 18 patients underwent surgery without ICG. Each group had one (5.5%) TD ligation. In the ICG group injury was detected intraoperative, and ligation was done at the site of injury. In all cases, the entire thoracic course of TD was visualized intraoperatively after a mean time of 81.39 min from ICG injection to visualization. The Mean extra time for ICG injection was 11.94 min. In the ICG group, no patient suffered from CT. One patient in the non-ICG group developed CT after surgery that was managed conservatively. According to Fisher's exact test, there was no significant association between CT development and ICG use, possibly due to the small sample size.
CONCLUSIONS
This study confirms that ICG administration into bilateral superficial inguinal lymph nodes can highlight the TD and reduce its damage during esophagectomy. It can be a standard method for the prevention of postoperative CT.

TECHNIQUE
The surgical management for high-output postoperative chylothorax typically necessitates ligation of the thoracic duct (TD) above the leak site and/or sealing the leak with a clip. However, pinpointing these structures during subsequent surgeries can be challenging due to their variable course and the presence of traumatized tissues surrounding the leak area. In response to this, we have developed a novel, fluorescence-guided technique that significantly enhances intraoperative identification of the leak point and the TD. This method was applied in the case of a 52-year-old man suffering from refractory chylothorax following a previous lung cancer surgery. This study documents the surgical procedure and includes a video vignette for a comprehensive understanding.
RESULTS
A bilateral inguinal lymph node injection of saline (10 mL), guided by ultrasound and containing 2.5 mg/mL indocyanine green (ICG), was administered 20 min prior to surgery. During thoracoscopic exploration, the leak point was precisely pinpointed in the right paratracheal area by transitioning from bright light to fluorescent mode. The TD was clearly identified, and upon ligation, there was no further leakage of fluorescent lymph, indicating a successful closure of the lymphatic structure. The surgery proceeded uneventfully, and the patient was able to resume oral intake on the third postoperative day. There was no evidence of recurring symptoms, leading to his discharge.
CONCLUSION
The intralymphatic injection of ICG offers a rapid visualization of the TD's anatomy and can effectively pinpoint the leak point, even amidst traumatized tissues. Moreover, it provides prompt feedback on the efficacy of ligation.
