Ureteral calculi after lingual mucosal ureteral reconstruction are rare. In this paper, we reported a case of a male patient who had undergone robotic-assisted laparoscopic lingual mucosal right ureteroplasty. Calculi were found in the right reconstructed ureteral segment 4 months after surgery. Then the patient underwent transurethral ureteroscopic holmium laser lithotripsy combined with a stone retrieval basket, and postoperative urological CT showed no residual calculi in the right ureter. No recurrence of right ureteral calculi or complications were observed during 20 months of follow-up.

【Objective】 To analyze the risk factors of ileus after radical cystectomy, and to construct a nomogram predictive model accordingly. 【Methods】 Clinical data of patients who underwent radical cystectomy during Jan.2018 and Dec.2021 were collected. The risk factors related to postoperative ileus were assessed with Logistic univariate and multivariate regression analysis. After that, the predictive model was constructed and its specificity and accuracy were verified. 【Results】 A total of 326 patients were included, 65 of whom developed ileus. Statistical analysis showed that gender, lymph node dissection, serum creatinine and albumin were correlated with postoperative ileus. The area under the receiver operating characteristic curve of the model was 0.769 (95%CI:0.724-0.802). Bootstrap correction curve showed that the model had good prediction accuracy. 【Conclusion】 Male, lymph node dissection, elevated postoperative serum creatinine and postoperative blood albumin decrease are predictors of ileus. The nomogram predictive model based on these predictors can predict the probability of ileus after radical cystectomy.

Objective:To explore the safety key points of total pancreaticoduodenectomy in the era of vascular resection technology and the important factors affecting rapid postoperative recovery.Methods:The clinical data of 52 patients with pancreatic cancer who underwent total pancreaticoduodenectomy in Beijing Chaoyang Hospital Affiliated to Capital Medical University from November 2014 to September 2022 were retrospectively analyzed, including 34 males and 18 females, aged (62±9). The intraoperative situation, incidence of postoperative complication, postoperative blood glucose control and postoperative survival rate were analyzed.Results:All operations of the 52 patients were successfully completed, including 48 patients underwent total pancreaticoduodenectomy combined with portal vein resection and allograft vascular grafts via artery approach. The portal vein occlusion time was (20±5) min. The incidence of postoperative complications was 28.8% (15/52), including 2 cases of abnormal gastric empty, 2 cases of diarrhea, 2 cases of chylous fistula, 4 cases of abdominal infection, 1 case of gastrointestinal fistula, 3 cases of gastrointestinal bleeding, and 1 case of pulmonary infection. Subcutaneous short-acting insulin injection was used to control blood glucose in the early stage after surgery, short-acting insulin combined with long-acting insulin was used for subcutaneous injection before sleep for diet recovery. All patients did not experience uncontrolled hyperglycemia. The median survival time of 52 patients was 13 months, and the longest follow-up time was 38 months. There were 37 patients died of tumor recurrence, 4 patients died of cardiovascular and cerebrovascular accidents, and 1 patient died of pulmonary infection in the 42 died patients.Conclusions:Total pancreaticoduodenectomy via artery approach can improve the R 0 resection rate in pancreatic cancer patients with vascular invasion, the rate of postoperative complication and mortality has no significant increase. The postoperative blood sugar control is satisfactory and the quality of life is guaranteed.
