Objective: Reliable methods to prevent chyle leakage after esophagectomy are needed. This retrospective study was performed to evaluate the correlation between low-fat nutrition and the incidence of chyle leakage after esophagectomy.

Methods: This multicenter retrospective case-control study involved patients who underwent Ivor Lewis esophagectomy from December 2012 to August 2017. Tube feeding was started on postoperative day 1 with a normal fat-containing formula (control group, 203 patients) or low fat-containing formula (241 patients).

Results: The patients in the control group and low-fat group had a similar incidence of chyle leakage (7 [3.4%] vs. 19 [9.4%], respectively) and anastomotic leakage (4 [2.0%] vs. 11 [5.4%], respectively). The multivariate logistic regression indicated that high-volume surgeon experience (performance of ≥100 esophagectomies per year) was correlated with a lower incidence of chyle leakage (odds ratio, 0.280; 95% confidence interval, 0.110-0.712), whereas low-fat nutrition was correlated with an increased risk of anastomotic leakage (odds ratio, 5.995; 95% confidence interval, 1.201-29.925).

Conclusion: Prophylactic low-fat enteral nutrition following esophagectomy might not decrease the risk of chyle leakage. More and better evidence is needed.

Postoperative chylothorax is a serious complication after oesophagectomy. Real-time identification of the thoracic duct (TD) could prevent injury or facilitate prompt management when it occurs. Intraoperative TD lymphography with indocyanine green (ICG) is a novel technique that may help prevent chyle leaks following thoracic surgery.

To investigate and compare the clinical efficacy and prognosis of D3 lymphadenectomy/complete mesocolic excision in treatment of right colon cancer with different medial boundaries. We searched The Cochrane Library, Pubmed, Embase, CBM, VIP, CNKI, and WanFang data bases for superior mesenteric artery (SMA)-oriented and superior mesenteric vein (SMV)-oriented D3 lymphadenectomy/complete mesocolic excision from inception to December, 2023. The resultant data were submitted to meta-analysis using RevMan 5.

Extra-adrenal, functional paraganglioma, if not medically controlled, requires early surgical resection. This can often be challenging when found in a retroperitoneal location, where resections are prone to lymphatic disruption and chyle leaks. Chylous ascites carry a significant risk of protein and caloric malnutrition, dehydration, and even mortality given the nutrient-rich characteristic of lost lymphatic fluid.

High-output Chyle leak is a dreadful complication following neck dissection, posing challenges in management due to the morbidity associated with prolonged leakage. This case series describes the efficacy of a novel Indocyanine Green (ICG) Fluorescence-guided Robotic Transthoracic thoracic duct ligation technique in intractable high-output chyle leaks following neck dissection. Three patients with persistent high-output chyle leaks following neck dissection underwent robot-assisted thoracic duct ligation.

Chylothorax is a rare condition in which chylous fluid accumulates in the pleural cavity, most often due to iatrogenic injury of the thoracic duct. This paper reports a case of a woman in her 50s presenting with chyle leakage after a video-assisted mediastinoscopic lymphadenectomy (VAMLA) for staging of a nodule suspected of non-small cell lung carcinoma. After the VAMLA, a Uniportal Video Assisted Thoracoscopic Surgery lobectomy was scheduled during which the chylothorax was observed.
