UNASSIGNED: There are no standard guidelines regarding the number and size of chest tubes that should be selected after thoracic surgery. This study aimed to evaluate the effects of adopting a drainage strategy with bi-pigtail catheters (BPCs) on patients undergoing lobectomy by uniportal video-assisted thoracic surgery (VATS).
UNASSIGNED: A retrospective study was performed of patients undergoing uniportal lobectomy at the Department of Thoracic Surgery of the Cancer Hospital of Dalian University of Technology between August 2021 and August 2022. The patients were divided into the following two groups according to the drainage strategy adopted: (I) a traditional chest tube (TCT) group; and (II) a BPC group. The outcomes measured included postoperative complications, as measured by the Clavien-Dindo method, and the visual analogue scale (VAS) pain scores of the patients after surgery.
UNASSIGNED: In total, 868 patients underwent lung resection during the study period, after exclusion, the data of 470 patients who underwent uniport lobectomy were reviewed (235 in the TCT group, and 235 in the BPC group). There were no statistically significant differences between the two groups in terms of baseline data (P>0.05). The incidence of postoperative complications (7.7% vs. 19.1%) and postoperative VAS pain scores at 7-24 hours (3.3±1.0 vs. 3.7±1.5) and 25-48 hours (3.1±0.8 vs. 3.6±1.5) were significantly lower in the BPC group than the TCT group (all P<0.001). Additionally, the postoperative length of stay (4.6±1.5 vs. 5.4±4.5 days) and the collapse rate of the residual lung (19.2%±9.1% vs. 20.9%±9.6%) of the BPC group were better than those of the TCT group (P<0.05). The results of univariable and multivariable analyses showed that a drainage strategy with a TCT was an independent risk factor for decreased postoperative complications, and reduced moderate or severe pain scores at 7-24 and 25-48 hours after surgery.
UNASSIGNED: Our drainage strategy with BPCs decreased the incidence of postoperative complications and alleviated the postoperative pain of patients undergoing lobectomy by uniportal VATS and is safe and feasible.

UNASSIGNED: This study aimed to provide a comprehensive overview of the complications unique to ureteral reconstruction in adults, emphasizing their presentation, diagnosis, and management in the treatment of ureteral structure disease.
UNASSIGNED: This review involves an in-depth analysis of existing literature and case studies pertaining to ureteral reconstruction, with a focus on examining the range of complications that can arise post-surgery. Special attention is given to the presentation of each complication, the diagnostic process involved, and the subsequent management strategies.
UNASSIGNED: Ureteral reconstruction can treat ureteral stricture disease with low morbidity; however, complications, although uncommon, can have severe consequences. The most notable complications include urinary extravasation, stricture recurrence, urinary tract infections, compartment syndrome, symptomatic vesicoureteral reflux, and Boari flap necrosis. Each complication presents unique diagnostic challenges and requires specific management approaches.
UNASSIGNED: Ureteral reconstruction is a highly effective treatment for ureteral stricture disease. Having a strong understanding of the potential complications that patients may experience following ureteral reconstruction is not only critical to adequately counsel patients but also facilitate prompt diagnosis and management of complications when they arise.

Splenic artery aneurysm (SAA) is the most common visceral artery aneurysm and can lead to severe outcomes if ruptured. This report presents the case of a 71-year-old female who experienced a sudden and severe gastrointestinal hemorrhage 19 years after undergoing pancreaticoduodenectomy for pancreatic head cancer. The patient arrived at the hospital with signs of shock, and imaging revealed an SAA rupture with associated gastric perforation. Emergency treatment involved endovascular techniques, which stabilized the patient and controlled the bleeding. This case highlights the importance of rapid diagnosis and the effectiveness of endovascular therapy in managing SAA rupture, particularly in patients with complex surgical histories.

UNASSIGNED: The combination of neoadjuvant immunotherapy and chemotherapy (NICT) has become a common treatment regimen for locally advanced gastric cancer (LAGC). However, the safety and efficacy of radical gastrectomy following NICT (NICT-G) remain controversial. This study aimed to analyze the risk factors influencing postoperative complications (POCs) after NICT-G. Additionally, it aimed to construct a nomogram to provide a clinical reference for predicting POCs.
UNASSIGNED: This study included 177 patients who received NICT-G at the Chinese PLA General Hospital First Medical Center from January 2020 to January 2024. Univariable and multivariable logistic regression models were used to evaluate the risk factors influencing POCs, and a nomogram model was constructed. To evaluate the discrimination and accuracy of the nomogram model, the area under the receiver operating characteristic curve (AUC) and the calibration curve were measured.
UNASSIGNED: In 177 patients who received NICT-G, the pathological complete response and major pathological response rates were 15.8% and 45.2%, respectively, whereas the rates of the overall and severe treatment-related adverse events were 71.8% and 15.8%, respectively. In addition, 43 (24.3%) patients developed overall POCs (Clavien-Dindo classification ≥ II). Univariable and multivariable logistic analyses showed that age ≥70 years, greater estimated blood loss, platelet/lymphocyte ratio (PLR) ≤196, neutrophil/lymphocyte ratio (NLR) >1.33, non-R0 resection, and body mass index (BMI) < 18.5 kg/m2 were independent risk factors for overall POCs (p < 0.05). The nomogram model developed using the abovementioned variables showed that the AUC (95% confidence interval [CI]) was 0.808 (95% CI): 0.731-0.885 in predicting the POC risk. The calibration curves showed that the prediction curve of the nomogram was a good fit for the actual POCs (Hosmer-Lemeshow test: χ2 = 5.76, P = 0.451).
UNASSIGNED: The independent risk factors for overall POCs in the NICT-G were age ≥ 70 years, greater estimated blood loss, PLR ≤ 196, NLR > 1.33, non-R0 resection, and BMI < 18.5 kg/m2. The nomogram model developed based on the abovementioned indicators showed better accuracy in predicting the POC risk.

OBJECTIVE: This research aimed to clarify the metastatic patterns of subcarinal, right and left recurrent laryngeal nerve lymph nodes in thoracic esophageal squamous cell carcinoma and to investigate appropriate strategies for lymph node dissection.
METHODS: Patients with thoracic esophageal squamous cell carcinoma receiving esophagectomy from December 2020 to April 2024 were retrospectively analyzed. Risk factors for subcarinal, right and left recurrent laryngeal nerve lymph nodes metastasis were determined by chi-square test and multivariate logistic regression analysis. We visualized the metastasis rates of these specific lymph nodes based on the different clinicopathological characteristics. Correlation between subcarinal, right and left recurrent laryngeal lymph nodes metastasis and postoperative complications were also analyzed.
RESULTS: A total of 503 thoracic esophageal squamous carcinoma patients who underwent esophagectomy were enrolled. The metastasis rates of subcarinal, right and left recurrent laryngeal nerve lymph nodes were 10.3%, 10.3%, and 10.9%, respectively. The lymphovascular invasion status and tumor location were the significant predictors for subcarinal and right recurrent laryngeal nerve lymph nodes metastasis, respectively (P < 0.001 and P = 0.013). For left recurrent laryngeal nerve lymph node metastasis, younger age (P = 0.020) and presence of lymphovascular invasion (P = 0.009) were significant risk factors. Additionally, pulmonary infection is the most frequent postoperative complication in patients with dissection of subcarinal, right and left recurrent laryngeal lymph nodes. There was no significant difference in the incidence of anastomotic leakage (P = 0.872), pulmonary infection (P = 0.139), chylothorax (P = 0.702), and hoarseness (P = 0.179) between the subcarinal lymph node dissection cohort and the reservation cohort. The incidence of hoarseness significantly increased in both right (P = 0.042) and left (P = 0.010) recurrent laryngeal nerve lymph nodes dissection cohorts compared by the reservation cohorts, with incidence rates of 5.9% and 6.7%, respectively.
CONCLUSIONS: The metastasis rates of subcarinal, right and left recurrent laryngeal nerve lymph nodes in thoracic esophageal squamous cell carcinoma were all over 10%. The dissection of subcarinal lymph nodes does not increase postoperative complications risk, while recurrent laryngeal nerve lymph nodes dissection significantly increases the incidence of hoarseness. Thus, lymph node dissection of subcarinal lymph nodes should be conducted routinely, while recurrent laryngeal nerve lymph nodes dissection may be selectively performed in specific patients.
