Objective To analyze the structural changes and reasons for hospitalization expenditure among patients with thyroid cancer,so as to provide a reference basis for reasonable control of medical costs,making the structure of hospitalisation costs for patients undergoing surgery for thyroid cancer more rational.Methods The degree of structural change and the grey correlation method were used to quantitatively analyze the changes in the structure of hospitalization expenses and the degree of correlation of patients with thyroid cancer surgery in a hospital in Shanxi Province from 2017 to 2022.Results From 2017 to 2022,the hospitalization expenses of thyroid cancer surgery patients in the hospital showed a decreasing trend,and drug fees and consumables fees accounted for a large proportion.Consumables fees and treatment fees showed positive contribution changes,drug fees and diagnosis fees showed negative contribution changes.Nursing fees and general medical service fees showed positive contribution changes,but were not obvious.During the 6-year period,the top two related factors affecting the hospitalization expenses of thyroid cancer patients were drug fees and consumables fees.Conclusion The structure of hospitalization expenses of per thyroid cancer patients tends to be reasonable,but there is still a large room for improvement.It is suggested to continue to strengthen the control of drugs and medical consumables,and clarify the value composition of technical labor and material consumables,so as to further optimize the structure of hospitalization expenses.

Objective: To evaluate the efficacy of a self-developed mobile augmented reality navigation system (MARNS) in guiding spinal level positioning during intraspinal tumor surgery based on a dual-error theory. Methods: This retrospective study enrolled patients diagnosed with intraspinal tumors admitted to Fujian Provincial Hospital between May and November 2023. The participants were divided into conventional x-rays and self-developed MARNS groups according to the localization methods they received. Position time, length of intraoperative incision variation, and location accuracy were systematically compared. Results: A total of 41 patients (19 males) with intraspinal tumors were included, and MARNS was applied to 21 patients. MARNS achieved successful lesion localization in all patients with an error of 0.38±0.12 cm. Compared to x-rays, MARNS significantly reduced positioning time (129.00±13.03 seconds vs. 365.00±60.43 seconds, p<0.001) and length of intraoperative incision variation (0.14 cm vs. 0.67 cm, p=0.009). Conclusion The self-developed MARNS, based on augmented reality technology for lesion visualization and perpendicular projection, offers a radiation-free complement to conventional x-rays.

Objective To compare the efficacy of retroperitoneal robot-assisted laparoscopic partial nephrectomy(RALPN)in the treatment of ventral and dorsal renal tumor.Methods The clinical data of 131 patients with renal tumor who underwent retroperitoneal RALPN at our hospital during Jan.2021 and Feb.2024 were retrospectively analyzed.The patients were divided into the ventral renal tumor group(n=35)and dorsal renal tumor group(n=96)according to preoperative images.Perioperative outcomes and prognosis were compared between the two groups.Results All 131 surgeries were successfully completed without conversion to open surgery or abdominal organ injury.There were no significant differences in warm ischemia time[median(interquartile range,IQR):20(16.75)min vs.22(IQR:15.25)min],operation time[57.0(IQR:29.5)min vs.58.5(IQR:39.75)min],estimated intraoperative blood loss[50(IQR:80)mL vs.50(IQR:80)mL],proportion of patients with intraoperative blood transfusion(0 vs.2.1％),proportion of patients using four arms during operation(42.9％vs.37.5％),postoperative reduction of hemoglobin(Hb)[(-12.9±9.0)g/L vs.(-11.5±9.4)g/L],reduction of estimated glomerular filtration rate(eGFR)[(-3.8±12.4)mL/min vs.(-7.0±13.6)mL/min],postoperative hospital stay[4(IQR:0)d vs.4(IQR:2)d],and proportion of meeting"Trifecta"criteria(94.3％vs.86.5％,P＞0.05).During the median follow-up of 9.8(5.5,24.0)months,no death occurred,and no recurrence or metastasis were observed except that bone metastasis occurred in 1 patient in the dorsal renal tumor group.Conclusion Both ventral and dorsal renal tumors can be treated with retroperitoneal RALPN,and the surgical outcomes of both are comparable.

Objective:To discuss the feasibility and safety of robot-assisted laparoscopic retroperitoneal tumor resection in prone position.Methods:From August 2023 to January 2024, a total of eight patients with retroperitoneal tumors from the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed, including two males and six females. The average age was (47.4±12.5) years, average BMI was (24.4±3.5) kg/m 2 and median ASA grade was 2(2, 3). Retroperitoneal tumors were identified preoperatively through CT or MRI. The imaging revealed 4 cases of adrenal tumors located on the left side, 2 on the right side, and 2 non-adrenal tumors situated on the left side. The preoperative diagnoses included 2 cases of non-functional adrenal tumors, 2 cases of pheochromocytoma, 1 case of Cushing’s syndrome, 1 case of metastatic renal cell carcinoma, and 2 cases of non-adrenal tumors. Robot-assisted laparoscopic retroperitoneal tumor resection was performed with all patients in prone position. The inferior margin of the fourth lumbar vertebra (L4) was determined by the line connecting the highest points of the iliac crests bilaterally. Subsequently, the inferior margins of the L1-L3 vertebrae were sequentially identified. The surgical field was then divided into three equal segments, utilizing the posterior midline of the spine and the midaxillary line as boundaries. The medial division was situated approximately at the lateral border of the vertical spinal muscles, while the lateral division was placed near the tip of the 12th rib. A longitudinal incision of approximately 3 cm in length was created within the lateral division between L2 and L3 for the insertion of a camera trocar. The extraperitoneal space was subsequently dilated using a self-made balloon, and two 8 mm trocars were placed as operative ports along the medial division and the midaxillary line, respectively, under finger guidance. Assistance trocars, one or two 12 mm in diameter, were introduced above the level of the iliac crest. During the operation, the extraperitoneal adipose tissue was removed and the Gerota's fascia was opened. For non-adrenal retroperitoneal tumours, the major blood vessels around the tumour were suspended and fixed, by titanium clips or Hem-o-lok clips to dissect the small arteries and veins, and the tumour was carefully isolated and completely resected. For adrenal tumours, the fat capsule around the upper pole of the kidney were removed, the adrenal gland was exposed, and then the tumour was removed completely along its capsule. If total adrenalectomy is performed, the central adrenal vein was clamped and dissected. The periphery of the adrenal gland was gradually dissected until the adrenal gland was completely removed.The perioperative data, including patient positioning time, trocar placement time, operation time, intraoperative blood loss, postoperative complications, postoperative hospital stay, and postoperative drainage tube removal time, as well as recurrence and metastasis, were recorded.Two patients underwent partial nephrectomy due to renal tumor, and only the time for retroperitoneal tumor resection was included in calculating operation time. Results:All 8 surgeries were successfully completed without dramatic blood pressure fluctuations.There was no conversion to open surgery or abdominal organ injury. The patient positioning time was (5.1±0.4) minutes, trocar placement time was (16.6±1.3) minutes, operation time was (28.8±13.8) minutes, intraoperative blood loss was (65.0±28.7) ml, postoperative hospital stay was (3.6±0.9) days, and drainage tube removal time was (2.8±1.0) days. No intraoperative or postoperative blood transfusions were required. Postoperatively diagnosed pathologies included: 2 cases of adrenal pheochromocytoma, 2 cases of adrenal sebaceous adenoma, 2 cases of retroperitoneal schwannoma, 1 case of adrenal myelolipoma, and 1 case of adrenal metastatic renal cell carcinoma. The average tumor size for all patients was (4.3±1.5) cm. After a follow-up of 2.0-7.2 months, there were no recorded postoperative complications, including haemorrhage, infections, acute hypotension, or adrenocortical insufficiency. Additionally, no evidence of tumor recurrence or metastasis was observed up during foolow-up.Conclusions:Robot-assisted laparoscopic retroperitoneal tumor resection in prone position could be a safe and feasible surgical approach with short operative time, low bleeding, and fast postoperative recovery.
