Patient satisfaction analysis of robot-assisted minimally invasive adrenalectomy: a single-center retrospective study.

The objective of this study is to compare the satisfaction of patients undergoing robot-assisted retroperitoneal laparoscopy adrenalectomy under the ambulatory mode and conventional mode. Basic information and clinical data of patients who underwent robotic-assisted posterior laparoscopic adrenalectomy between June 2020 and June 2023 were queried from our case system. The Outpatient and Ambulatory Surgery Consumer Assessment of Healthcare Providers and Systems Survey (OAS CAHPS®) was used to investigate patient satisfaction with preoperative preparation, discharge counseling, postoperative instructions, postoperative pain, and satisfaction with nursing work. The stats R package was used to select the appropriate statistic for the statistics based on the characteristics of the data. A total of 311 patients who underwent robot-assisted posterior laparoscopic adrenalectomy were enrolled in our case system. There were no statistical differences between the two groups in gender, age, body mass index, ASA classification, laterality, maximum tumor diameter, type of resection, hormonal activity, disease type, pathological classification, duration of surgery, estimated intraoperative bleeding, postoperative complications and follow-up period that were compared between the two groups of patients. There were no significant differences in preoperative preparation score, discharge counseling score, postoperative guidance score and nursing care satisfaction score (P > 0.05). Postoperative hospitalization, peristalsis time, defecation time, time to first postoperative mobilization, duration of indwelling drain and hospitalization costs in patients in the ambulatory model group were significantly less than patients in the conventional model group (P < 0.001). Patients in the ambulatory model group had significantly higher postoperative pain relief scores than patients in the conventional model group. In conclusion, our data suggest that patient satisfaction is equal between the conventional and ambulatory mode of performing robotic-assisted adrenalectomy. Patient satisfaction was probably associated with shorter hospitalization days, adequate preoperative preparation and standardized, high-quality post-discharge information and guidance.

Analysis of the influencing factors for postoperative chronic kidney insufficiency in patients with primary aldosteronism / 中华泌尿外科杂志

Objective:To explore the influencing factors of postoperative chronic kidney disease (CKI) in patients with primary aldosteronism (PA).Methods:The clinical data of 103 patients who underwent adrenalectomy for PA in our center from August 2018 to August 2019 were analyzed retrospectively. There were 53 males and 50 females, aged (47.02±10.06) years old, including 27 diabetes patients (26.2%). The body mass index (BMI) were (24.47±3.24) kg/m 2, tumor maximum diameter were (15.61±5.66) mm, preoperative systolic blood pressure were (166.93±12.22) mmHg(1 mmHg=0.133 kPa), preoperative blood potassium were (3.35 ± 0.48) mmol/L, plasma aldosterone concentration (PAC) were (55.75±8.56)ng/dl, aldosterone-renin ratio(ARR) were (165.13±38.21) and preoperative glomerular filtration rate (GFR) were (77.96±14.77) ml/(min·1.73m 2). All patients underwent laparoscopic adrenalectomy. The operation time and bleeding volume were recorded. The GFR, blood potassium, PAC and ARR were recorded at the third month after surgery. The paired sample t test was used to compare GFR before and after surgery. Pearson correlation analysis was used to evaluate the correlation between the parameters and GFR after surgery. The independent predictors of GFR≤60ml/(min·1.73 m 2) were analyzed by univariate and multivariate logistic regression. Results:The surgery time were (85.37±21.66) min, and the bleeding volume were (10.54±4.84) ml. GFR (62.66±8.53) ml/(min·1.73 m 2) at 3 months after surgery was significantly different from that before surgery ( P<0.01). Univariate analysis showed that age ( OR=1.36, P<0.01), preoperative GFR ( OR=0.81, P<0.01), preoperative blood potassium ( OR=2.95, P=0.02), preoperative PAC ( OR=1.28, P<0.01) and preoperative ARR ( OR=1.08, P<0.01) were significantly correlated with postoperative CKI. In Pearson analysis, older age ( r=-0.51, P<0.01), lower preoperative GFR ( r=0.62, P<0.01), lower preoperative blood potassium( r=0.41, P=0.02), higher preoperative PAC ( r=-0.49, P<0.01) and higher preoperative ARR ( r=-0.56, P<0.01) increased the risk of CKI. Multivariate logistic regression analysis showed that age ( OR=1.26, P=0.05), preoperative GFR ( OR=0.79, P=0.02) and preoperative PAC( OR=1.29, P=0.01) were independent risk factors for postoperative CKI. Conclusions:CKI may occur in PA patients after adrenalectomy. PA patients with older age, higher preoperative PAC, higher preoperative ARR, lower preoperative blood potassium and lower preoperative GFR are more likely to have CKI. Age, preoperative GFR and preoperative PAC were independent predictors of CKI.

Correlation of metallothionein-2A, E-cadherin and cyclin E with biochemical recurrence in prostate cancer / 肿瘤研究与临床

Objective To investigate the expressions of metallothionein-2A (MT-2A), E-cadherin, interleukin-6 (IL-6), cyclin E, proliferating cell nuclear antigen (PCNA) and bcl-2 in prostate cancer tissues and their correlation with biochemical recurrence of prostate cancer. Methods Tissue specimens from 128 cases of prostate cancer who underwent radical prostatectomy in Shanxi Dayi Hospital from October 2012 to October 2017 were processed and transferred into tissue microarrays, the clinicopathological parameters of patients were also recorded. The expression levels of MT-2A, E-cadherin, IL-6, cyclin E, PCNA and bcl-2 were detected by immunohistochemical avidin-biotin complex (ABC) staining. The correlation between different molecular markers and biochemical recurrence of prostate cancer was analyzed. Results The biochemical recurrence rate of 128 patients with prostate cancer was 30.5％ (39/128). The biochemical recurrence rates of low-risk, intermediate-risk and high-risk prostate cancer patients were 14.8％(8/54), 38.7％(24/62) and 58.3％ (7/12), respectively. The risk classification and pathological T stage of patients with prostate cancer were associated with the expressions of MT-2A, cyclin E, IL-6 and E-cadherin (all P< 0.05). Multivariate Cox risk model showed that the high risk classification (HR= 1.81, 95％CI 1.56-2.19, P=0.042), MT-2A positive expression (HR= 2.01, 95％CI 1.08-3.15, P= 0.005), cyclin E positive expression (HR= 1.79, 95％CI 1.08-2.21, P= 0.042) and E-cadherin negative expression (HR= 1.92, 95％ CI 1.22-2.45, P= 0.020) were the independent risk factors for biochemical recurrence of prostate cancer. Conclusion The expression of MT-2A, cyclin E and E-cadherin may serve as independent predictors for biochemical recurrence of prostate cancer.

Diagnosis and treatment of active adrenal tuberculosis: case report and literature review / 中华泌尿外科杂志

Objective To investigate the diagnosis and treatment of active adrenal tuberculosis.Method The clinical data of 1 patients with adrenal tuberculosis was retrospectively analyzed and the related literatures were reviewed.The male patient,54 years old,complained abuot the dry cough and intermittent fever for 9 months.He was found the left adrenal gland tumor for 1 weeks and admitted to our hospital on November 1st,2016.The physical examination showed the obvious left kidney percussion tellderness.The local hospital,considered the left adrenal tumor.The pathological diagnosis of left adrenal tumor by biopsy was chronic inflammation.The patient accepted anti-inflammatory therapy,but his symptom was not relieved.In our hospital,blood bacterial culture and urine bacterial culture and PPD was negative.Blood tuberculosis antibody was positive.Triple acid-fast bacilli were negative in urine.Chest CT did not exclude the interstitial pulmonary tuberculosis.Adrenal contrast-enhanced CT showed mild enhancement,strip calcification shadow.Primary diagnosis was left adrenal tumor,which the abscess and tuberculosis could not to be excluded.Then,the patient accepted regularly anti-tuberculosis therapy (Isoniazid,0.3 g/d,rifampicin,0.45 g/d,ethambutol,0.6 g/d).Mter 3 days,his temperature returned to normal.Since the left adrenal mass was too large,which was about 6.8 cm × 5.5 cm,to distinguish with the tumor,the patient accepted successfully retroperitoneal adrenal tumor resection two weeks later.The left adrenal tumor surface was greyish and yellow,which was adherent with spleen and pancreas.After carefully separating,the tumor was successfully removed.Result The operation was successful,which last 85 min.Intraoperative blood loss was about 50 ml.Pathological report showed adrenal tuberculosis.The patients accepted regularly antituberculosis therapy(Isoniazid,0.3 g/d,rifampicin,0.45 g/d,ethambutol,0.6 g/d) for half a year,and followed up for 1 year after operation.No further hormone replacement therapy was used.No fever was noticed and his rhythm cortisol level was normal.Conclusions Adrenal mass associated with recurrent fever,should be suspected as adrenal tuberculosis if antibiotic therapy is not effective.If the adrenal CT showed adrenal calcification associated with the ectepic tuberculosis,patient should be diagnosised active adrenal tuberculosis.They should accept anti-tuberculosis treatment.However,if the volume of tuberculosis is large,or not to exclude tumor possibility,we recommend to proceed adrenal tumor resection for diagnosis.

Hypo-androgen adrenocortical oncocytoma: 1 case report and literature review / 中华泌尿外科杂志

Objective To analysis the clinical features,diagnosis,treatment and prognosis of adrenal eosinophilic tumor with low testosterone levels.Methods The clinical data of a 22 years old male patient with adrenal eosinophilic tumor and low testosterone levels was analyzed.Blood pressure was 151/88 mmHg.The patient got bilateral gynecomastia.His bilateral testicular was soft and became smaller,with short penisr.Endocrine examination results showed:Estradiol 666 pg/ml,Prolactin 19.08 ng/ml,Testosterone 0.18 ng/ml,follicle stimulating hormone ＜ 0.2 U/L.The CT showed the mass density of soft tissue in the left adrenal region with diameter 7 cm,which was inhomogeneous and enhanced.There were many small vessels enhanced in the CT arterial phase,and the blood flow in the tumor was abundant.Clinical diagnosis of left adrenal tumor was pheochromocytoma.The patient underwent laparoscopic left adrenal tumor resection.The left adrenal gland was located in the superior pole of the left kidney,and there was an independent supply of the artery.Results Pathological result showed the tumor weigh was 60 g,7 cm in diameter and brown in section.The tumor cells were arranged in solid nests or acini,with more eosinophilic granules in cytoplasm.The nuclei was round and the nucleoli was located in the center,had clusters of pleomorphic and clustered cells.The tumor was wrapped in a thick fibrous envelope,mainly consisted of eosinophils,granulation tissue.There was no necrosis,mitosis,and vascular invasion.Immunohistochemical staining showed that the expression of CD56 and syn protein was positive.Pathological diagnosis was left adrenal eosinophilic tumor.After 4 months,the blood testosterone levels rose to 3.90 ng/ml,the blood pressure returned to normal (118/75 mmhg).The estradiol (21 pg/ml) was significantly inhibited.The patient began to appear beards and breasts became smaller.There were no signs of clinical or imaging recurrence.After 16 months follow-up,serum testosterone was 4.68 ng/ml and serum estrogen levels dropped to 33 pg/ml.Semen routine showed no sperm.Conclusions The clinical morbidity of functional adrenocortical oncocytoma with low testosterone levels and high estradiol levels is low.The pathological components are mainly eosinophilic granulation tissue.The adrenocortical oncocytoma are rare and preoperative diagnosis is difficult.Clinical manifestation,imaging examination and adrenal biochemistry examination should be considered to determine the localization and qualitative of tumor.Minimally invasive surgery is an effective treatment.The close follow-up after operation is essential.

The role of self-retaining suture in retroperitoneal laparoscopic partial nephrectomy for complicated renal tumor / 中华泌尿外科杂志

Objective To evaluate the efficacy of self-retaining suture (QuillTM SRS) in retroperitoneal laparoscopic partial nephrectomy for complicated renal tumor by assessing perioperative parameters.Methods Between 2010 and 2012,78 cases of complicated renal tumor (R.E.N.A.L score ≥ 7) treated by retroperitoneal laparoscopic partial nephrectomy (LPN) with two layers continuous knotless barbed suture (QuillTM SRS group) (n=30) or traditional absorbable vicyl suture (non-SRS group) (n=48) were retrospectively analyzed.In QuillTM SRS group,2-0 Quill SRS was used to suture the deep wound bed,and the second outcr layer renorrhaphy was performed with a 1-0 Quill SRS by the same way.In non-SRS group,the inner layer was sutured using a 15cm in length 2-0 monicryl suture by the same method mentioned above.A second outer layer was sutured with 1-0 vicryl suture across the wound.Cases were matched for R.E.N.A.L score.Comparison was made in term of operation time,preoperative parameter and perioperative complications between SRS group and non-SRS group.Results Renorrhaphy was successfully performed in all cases except 1 case converting to open surgery in non-SRS group.Mean warm ischemia time in SRS group was shorter than non-SRS group (18 vs 25 min,P =0.021).The proportion of bleeding requiring intervention in the non-SRS group (7/48,14.5％) was 4.3-fold higher than that of the SRS group (1/30,3.3％),but the differernce is not significant (P＞0.05).There were no significant differences between two groups in postoperative creatinine changes.Limitations of this study include the absence of randomization and the relative small sample size.Conclusions SRS can be safely used for complicated renal tumor during LPN,and SRS can significantly reduce the WIT and may also reduce bleeding during the operation.
