Objective:To explore the feasibility, safety and clinical efficacy of ileum augmentation cystoplasty assisted by Da Vinci robot for the treatment of neurogenic bladder.Methods:Retrospective analysis was performed on the data of 12 patients with neurogenic bladder admitted to Zhejiang Provincial People’s Hospital from March 2017 to November 2018, including 11 males and 1 female, with the mean age of 38(12-67). Preoperative symptoms were urinary incontinence, dysuria, decreased bladder capacity, or increased bladder pressure leading to ureteral reflux. All the 12 patients underwent preoperative intermittent catheterization, including 8 patients with spinal cord injury and 4 patients with spinal cord dysplasia. Preoperative serum creatinine(129.58±44.60)μmol/L and total glomerular filtration rate(61.63±18.04)ml/(min·m 2) were observed in 12 patients. Preoperative urodynamic examination showed the safe bladder volume of (95.67±39.10)ml, bladder internal pressure of(63.30±6.02)cmH 2O(1 cmH 2O=0.098 kPa)at the end of filling period, bladder compliance of(10.24±1.14)ml/cmH 2O, residual urine volume of(152.58±80.89)ml, and urine flow rate of(3.88±3.63)ml/s. Bladder contracture was evident on preoperative cystography. Ultrasound examination showed different degree of hydronephrosis and ureter expansion, in all cases, with ureteral reflux grading Ⅰin 2 cases, grade Ⅱ in 4 cases, grade Ⅲ in 4 cases, grade Ⅳ in 2 cases. All the 12 patients underwent robot-assisted ileum augmentation cystoplasty with 5-point puncture. Transverse incision of the bladder wall before full thickness, according to the amount of bladder and quality to decide 30 cm(normal), longitudinal cut back loops and one point after suture fixation in the bladder wall midpoint, fixed point as starting point, in turn, will be blind to the bladder stitching on both sides, the bilateral ureteral placing a single J tube respectively, evaluation of surgical success rate (including intraoperative bleeding, interception of bowel loops are no damage adjacent viscera, ureter openings with and without damage, impermeability, match insufflate whether unobstructed), postoperative complications, anastomotic fistula, intestinal obstruction, abdominal bleeding), urine dynamics test parameters, and patients’ quality of life. Patients were regularly given anticholinergic drugs(2 mg/d) for 6 months after surgery. Results:All the 12 cases in this group were successfully completed without any transfer to open surgery. The operation time was(120.8±12.0)min. Intraoperative blood loss(84.0±23.2)ml. Postoperative intestinal function recovery time(3.3±1.3) d. Postoperative hospital stay(12.1±3.1)d. Postoperative pelvic drainage tube indwelling time (3.8±1.2) d. Catheter and single J tube were removed 2 weeks after operation. Postoperative follow-up averaged 19.4(3-24) months. At 3, 12, 24 months after surgery, the bladder safety volume was rechecked(435.83±33.56), (450.90±31.09), (462.00±33.72)ml, the bladder internal pressure at the end of filling was(18.60±0.92), (15.70±1.42), (12.96±1.34)cmH 2O, the blood creatinine level was(81.43±21.10), (74.34±15.70), (72.90±15.90)μmol/L, and the bladder compliance was(37.94±4.22), (40.40±3.98), (43.42±4.20)ml/cmH 2O and the total glomerular filtration rate(91.52±9.49), (102.18±5.65), (112.41±6.50)ml/(min·m 2) were significantly improved compared with those before surgery( P<0.001). After 24 months of bladder urination training, 1 patient could basically urinate by herself. Three patients were treated with intermittent urinary catheterization supplemented by automatic urination. The remaining 8 patients were completely dependent on urinary catheter for intermittent catheterization. Postoperative complications such as anastomotic fistula, ileus and abdominal bleeding were not found in 12 patients. Conclusions:Ileum bladder enlargement assisted by robot can effectively expand bladder volume, reduce bladder internal pressure, improve bladder compliance, prevent ureteral reflux and protect renal function.

Objective: To analyze the main causes for unplanned re-operation of prostatic cancer. Methods: The clinical data of 4 patients with prostatic cancer who underwent an unplanned re-operation were analyzed retrospectively between September 2014 and July 2019 in our hospital.Preoperative data of patients was collected as follows: mean age of 65 years, ranged from 56 to 71 years.tPSA ranged from 5.17-13.20 ng/ml.Gleason score of 3+ 3 in 1 case, 3+ 4 in 2 cases, 4+ 4 in 1 case. pTNM pT_2a in 2 Cases, pT_2b in 2 cases. LRP(extraperitoneal approach) in 1 case, RARP(transperitoneal approach) in 3 cases. Results: The main causes for unplanned re-operation were as follows: perioperative hemodynamic instability(75%, 3/4), post-operative fever(25%, 1/4). All 4 re-operations were performed by urologists using Laparoscopic exploration of abdomen. Conclusions Inadequate and inappropriate surgical hemostasis are the key to lead a second-look surgery of prostatic cancer.A complete hemostasis could help to lower the re-operation rate.Laparoscopic exploration of abdomen could be one of the choices to deal with re-operation after minimally invasive radical prostatectomy.

Objective:To Investigate the postoperative sexual function outcomes in patients with bladder cancer who underwent robot-assisted radical cystectomy (RARC)or laparoscopic radical cystectomy(LRC)followed by orthotopic neobladder reconstruction.Methods:We performed a retrospective review of 84 bladder cancer patients having undergone laparoscopic radical cystectomy(LRC)and robotic-assisted radical cystectomy(RARC)with≥21 IIEF-5 in our institution from Jan 2014 to Jan 2019. All of them were diagnosed as high grade urothelial carcinoma by biopsy or TURBT. Biopsy of the posterior urethra and bladder neck reveal negative result of tumor invasion. Their PSA level was less than 4.0 ng/ml with negative result of DRE. All patients undergone laparoscopic radical cystectomy and orthotopic neobladder reconstruction by one medical team. 45 patients underwent robotic assistant radical cystectomy(RARC group), and the rest of patients 39 were treated with laparoscopic radical cystectomy(LRC group). In RARC group, the mean age were 53 years old(ranging 50-67 years old)and clinical stage of the tumor was cT 1 in 10 patients, cT 2 in 21 patients and cT 3 in 14 patients. In the LRC group, the mean age were 56 years old(ranging52-65 years old) and the clinical staging of the tumors was 6 patients in cT 1, 23 patients in the cT 2 and 12 patients in the cT 3. The RARC group paid special attention to the protective function of the following surgical details: ①To detect the abdominal organs, reveal the pelvic cavity, observe the blood vessels and ureter, open the perinatal membrane next to the cross of the ureter, along the outer venous veins and closed-hole nerves around the standard or expand the pelvic lymph node cleaning. In this study, the patients who did not have obvious suspected lymph node metastasis were removed within the standard range of the pelvic lymph nodes on both sidesin order to protect the nerves at the pelvic floor as much as possible. ② With the robot 3rd arm lifting the bladder, the peritoneum was opened at the site of seminal vesicle and ampulla of vas deferent duct, which connected to the two sides with the open peritoneum. Along the vasectomy and the sac free, the denonvillier fasica was opened and exposing the back of the prostate. With the third arm pulling down, the umbilical ligament was observe. The peritoneal was opened to the retropubic space so that the prostate region was revealed. Continue to dissect the bladder front space until the pelvic fascia and the osteopathic prostate ligament are exposed. The Hem-o-1oks were used to ligate the bilateral bladder lateral ligaments. The bladder and prostate were removed in the fascia level. The NVB bundle on both sides was kept to the apex of prostate. The urethra was exposed and remove the catheter.With Hem-o-lok clamping, the urethra was dissected in the level of prostatic apex. The distal end of urethral tissue was sent to the rapid freeze pathology examination. In the procedure of prostate removing, parallel prostate fascia excision was considered and pubo-prostatic ligament could be preserved.③ Preserving the bilateral neurovascular bundle (NVB) and try to avoid the damage of NVB. Retaining the bladder lateral ligament neurovascular bundle. Retaining the1.2-1.5 cm urethra and surrounding continent control structure. The cold knife is advocated. Blood vessel clamp can be used to stop bleeding. We compared with operative time, bleeding amount, postoperative hospitalization, IIEF-5 scores and satisfaction of sexual between those groups. Results:All operations were successfully performed without conversion and serious surgical complications. The operative time in the RARC group and LRC group were [(313.5±31.9)min and (276.5±32.3)min, P>0.05] .The intraoperative amount of blood loss and postoperative hospitalization were [(190.1±44.1) ml and (212.3±39.2) ml, P>0.05], [(14.3±2.1) d and (15.2±3.0) d, P>0.05]. There was no significantly difference between the two groups. The median follow-up period of 84 patients was 18 months. The IIEF-5 score of the RARC group was higher than LRC group at 6 months(18.5±1.6 vs.10.6±1.3)and 12 months (18.6±2.4 vs.11.2±1.4) ( P<0.05). In addition, the satisfaction of sexual in the RARC group was relative better than LRC group (both P<0.05) at 6 months[44.4%(20/45)vs.25.6%(10/39)], and 12 months[51.1%(23/45) vs.28.2%(11/39)] post-operation. Conclusion:Robot-assisted radical cystectomy(RARC) and orthotopic neobladder reconstruction revealed relative better recovering in post-operative sexual function and improvements in patient quality of life.

Objective:To determine the impact of body mass index (BMI) on perioperative and oncological outcomes after robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion.Methods:Clinical data of bladder cancer patients undergoing robot-assisted radical cystectomy with intracorporeal urinary diversion in Zhejiang Provincial People's Hospital from January 2017 to January 2020 were retrospectively analyzed. Patients were divided into three groups according to BMI, including 61 cases in normal group (<25.0 kg/m2), 52 cases in overweight group (25.0-29.9 kg/m2) and 33 cases in obese group (≥30.0 kg/m2). In the normal group, the median age was 73.6(59, 79), including 45 male(73.8%), with 51 cases(83.6%) of ASA score 0-2, 10 cases (16.4%)of 3 or higher, and 10 cases (16.4%) undergoing neoadjuvant chemotherapy. Past medical history included smoking in 34 cases (55.7%), hypertension in 19 cases (31.1%), diabetes in 10 cases (16.4%), heart disease in 12 cases (19.7%), and abdominal surgery in 6 cases (9.8%). In the overweight group, the median age was 69.7(60, 78), including 38 male (73.1%), with 25 cases (48.1%)of ASA score 0-2, 27 cases (51.9%) of 3 or higher, and 9 cases (17.3%) undergoing received neoadjuvant chemotherapy. Past medical history included smoking in 30 cases (57.7%), hypertension in 20 cases (38.5%), diabetes in 10 cases (19.2%), heart disease in 9 cases (17.3%), and abdominal surgery in 5 cases (9.6%). In the obses group, the median age was 69.9(61, 78), including 21 male(63.7%), with 20 cases (60.6%)of ASA score 0-2, 13 cases(39.4%) of 3 or higher, 9 cases (27.3%) undergoing neoadjuvant chemotherapy. Past medical history included smoking in 18 cases (54.5%), hypertension in 17 cases (51.5%), diabetes in 19 cases (57.6%), heart disease in 7 cases (21.2%), and abdominal surgery in 4 cases (12.1%). After statistical comparison among the three groups, it was found that the proportion of patients with hypertension and diabetes in the obesity group and overweight group was higher than that in the normal group (all P<0.05), but there was no significant difference in other factors (all P>0.05). During the surgical process, robot-assisted radical cystectomy and bilateral pelvic lymph node dissection were performed firstly. The scope of lymph node dissection was divided into standard range and expanded range, and the diversion was divided into orthotopic neobladder and ileal bladder. During the orthotopic neobladder process, 40-50 cm ileum at the distance of 15 cm away from ileocecum was obtained by stapler, and then the U-shaped neobladder was made, and the new bladder was anastomosed with urethra and bilateral ureter. For ileal bladder, the ileum was cut off 15cm away from the ileocecum with stapler to obtain the 15 cm ileum to prepare the ileal conduit and restore the continuity of the ileum. The bilateral ureteral spacing 3cm was implanted on the ileal conduit. In the normal group, standard range lymphatic dissection was performed in 20 cases (32.8%), enlarged dissection in 41 cases (67.2%), orthotopic neobladder in 22 cases(36.1%), and ileal conduit in 39 cases (63.9%). In the overweight group, standard range lymphatic dissection was performed in 12 cases (23.1%), enlarged dissection in 40 cases (76.9%), orthotopic neobladder in 26 cases (49.1%), and ileal conduit in 26 cases (50.9%). In the obesity group, the standard range of lymphatic dissection was performed in 7 cases (21.2%), enlarged dissection in 26 cases (78.7%), orthotopic neobladder in 7 cases (21.2%), and ileal conduit in 26 cases (78.8%). There was no significant difference among the three groups (all P>0.05). Compared the operation time, intraoperative blood loss, postoperative exhaust time, postoperative time of taking solid food, postoperative hospital stay, postoperative complications (according to the Clavien-Dindo grading system, postoperative complications are reported inⅠ-Ⅱ grade as mild complications and above Ⅲ grade as serious complications) and pathology results in three groups. Results:All cases successfully underwent robotically without conversion or major intraoperative complications. The operation time in overweight and obsess group were longer than that of normal group with RARC or orthotopic neobladder [310(250, 350) min, 370(310, 420) min, 250(230, 310) min, ( P<0.05)], but there was no significant difference in RARC and ileal conduit[270(220, 300) min, 280(230, 300) min, 240(220, 290)min, P>0.05]. The estimated blood loss in overweight and obsess group was more than that in normal group [230(150, 450)ml, 310(250, 600)ml, 190(100, 350)ml, P<0.05], but there was no difference in blood transfusion rate [4(7.7%), 2(6.1%), 5(8.2%), P>0.05]. The exhaust time [2(1, 3) days, 2(1, 4)days, 2(1, 4)days], postoperative solid food intake time [4(3, 5)days, 4(3, 6)days, 4(3, 6)days] and the hospital stay[10(5, 16)days, 10(6, 17)days, 12(6, 20)days] were not different in three groups(all P>0.05). The mild complication rates in 90 days were significant higher in overweight and obsess groups[28 (53.8%), 16(48.5%), 20(32.8%), P<0.05], but the total and severe complication rates were not significantly different. The incidences of urinary system complications and incision complications in obese and overweight patients were significantly higher than those in normal group ( P<0.05). There was no significant difference in the incidence of gastrointestinal complications and ureteral anastomosis-related complications (stricture or urinary leakage)( P>0.05). There was no significant difference in the number of dissected lymph node, positive lymph node, positive rate of incisional margin and postoperative pathological stage among three different BMI groups(all P>0.05). Conclusion:Robot-assisted radical cystectomy combined with intracorporeal urinary diversion is a safe and effective method for the treatment of overweight, obese and even morbidly obese patients with bladder cancer. The recovery of intestinal function and the oncological results are not affected by body mass index. However, laparoscopic radical cystectomy for overweight and obese patients, especially for orthotopic neobladder, has the risk of long operation time, large amount of intraoperative bleeding and increased risk of minor postoperative complications.

Objective To discuss outcome and safety after implementation of enhanced recovery after surgery(ERAS) protocols to patients who underwent robotic assisted radical cystectomy (RARC) with intracorporeal orthotopic "U" shaped ileal neobladder creation using STAPLER technique.Methods Between October 2014 and April 2019,71 patients(59 males and 12 females)with MIBC (Muscle Invasive Bladder Cancer) who underwent RARC with intracorporeal urinary diversion using orthotopic "U" shaped ileal neobladder in Zhejiang Provincial People's Hospital (People's Hospital of Hangzhou Medical College) were studied retrospectively.They had an average age of (65.2 ± 5.6)y and BMI of (22.18 ± 3.75) kg/m2.The median age-adjusted charlson comorbidity index (aCCI) was 4,median ASA score was 2.All patients underwent these inspections pre-RARC:chest Xray,vascular ultrasound (jugular vein included),abdominal ultrasound,CT urography,cystoscopy with biopsy or TURBT(trans-urethral resection of a bladder tumour).All patients were pathological diagnosed with MIBC,with no evidence of systemic metastasis and no history of radiotherapy,systemic chemotherapy and open abdominal surgery before RARC.All 71 patients received RARC with intracorporeal orthotopic "U" shaped ileal neobladder creation using STAPLER technique.Between October 2014 and September 2016,37 cases (29 males and 8 females) were managed without ERAS protocols perioperatively.They had an average age of (65.3 ±5.7)y and BMI of (23.66 ± 3.47)kg/m2.The median aCCI was 4,median ASA score was 2.Between October 2016 and April 2019,another group of 34 cases (30 males and 4 females) were managed with ERAS protocols including nutritional assessment,thrombosis prevention,pain assessment and management,perioperative diet management etc.They had an average age of (64.5 ± 4.3) y and BMI of (21.87 ± 4.85) kg/m2.The median aCCI was 4,median ASA score was 2.There were no statistical significance between the two groups with regard to general information.Surgical and follow-up data were collected for all patients.Results Surgeries were successful in all 71 cases with postoperative follow up for 3-51 months.In ERAS group,there were 22 cases in pT2 and 12 cases pT3 according to classification of malignant tumours:with 2 cases of incidental prostate cancer (IPCa).In non-ERAS group,pT2 in 25 cases and pT3 in 12 cases:with 1 case of IPCa.Statistical significance were observed between groups with regard to the first anal exhaust time [(20.5 ± 18.7) h vs.(29.9 ± 17.4)h,P =0.032],the first defecation time [(72.6 ±27.1)h vs.(88.7 ±35.8)h,P =0.004],length of hospital stay after surgey [(14.1 ± 3.3) d vs.(16.2 ± 4.8) d,P =0.037],numeric rating scales (NRS) Pain Score 8.0,24.0,48.0 h after surgery [(3.2 ±0.5)vs.(3.6 ±0.8),P =0.015;(1.9 ±0.3) vs.(2.2 ± 0.6),P =0.011;(1.3 ± 0.4) vs.(1.6 ± 0.7),P =0.032],respectively.There were no significance between groups with regard to operating time [(290 ± 65) min vs.(282 ± 46) min,P =O.549],intraoperative blood loss [(190.5 ± 235.6) ml vs.(221.1 ± 250.3) ml,P =0.438],transfusion rate [5.9％ (2/34) vs.8.1％ (3/37),P =0.922],readmission within 30 days after surgery [2.9％ (1/34) vs.5.4％ (2/37),P =0.940],early severe complications(within 30 days) [2.9％ (1/34) vs.2.7％ (1/37),P =0.940],late severe complications (after 30 days) [5.9％ (2/34) vs.8.1％ (3/37),P =0.922].Conclusions The implementation of ERAS protocols to patients who underwent RARC with intracorporeal orthotopic "U" shaped ileal neobladder using STAPLER technique is safe and effective.It can reduce postoperative pain and hospital stay,shorten bowel recovery time,improve early functional recovery without increasing major complications.This adoption should be encouraged.

Objective:To discuss the effect and experience of laparoscopic vesicovaginal fistula repairs though inferior of bladder longitudinal incision.Methods:54 patients were included in this study. Clinical data of patients collected from our hospital since January 2010 to October 2019 who underwent laparoscopic vesicovaginal fistula repair. The median age is 49.5 (8-80) years old. Main complaints were urine flows out through the vagina. 14 cases (25.9%) and 23 cases (42.6%)were post-hysterectomy of benign lesions and gynecological malignant tumors. The symptoms presented at 11 (1-20) days post urinary catheter removal. There were 11 cases (20.4%) of cervical malignant tumors, symptoms presented at 10 (5 to 25) months after radiotherapy. The symptoms of rest of cases 6 (11.1%)presented at 21 (3 to 50) days. One of them had rectal fistula, another had ureteral injury, 6 had bladder contracture, 2 patients had bilateral hydronephrosis. Preoperative CT examination revealed that 4 cases had no obviously hydroureter at upper urinary tract, and 2 cases had mild hydronephrosis in bilateral kidneys. The diameter of the fistula was 0.5-4.0 cm. There were 50 cases of single fistula and 4 cases of multiple fistula. The urine pad test evaluated the degree of urine leakage in patients reveals that 7 and 42 cases with mild and moderate, rest of 5 cases presented with severe result. 37 cases performed with vesico-vaginal fistula repair for the first time; 13 and 2 cases had once and twice vesico-vaginal fistula repair history and there were other two patients had vesico-vaginal fistula repair history for three and four times. All patients underwent general anesthesia under the laparoscopic bladder bottom longitudinal incision bladder vaginal fistula repair, 8 cases performed with Da Vinci robotic assist surgery system. Main steps of the operation include: ①search for bladder and vaginal fistula, assessed the size, number, and location of the fistula; ②To set single J stents in the bilateral ureter; ③Fully separated the bladder and vaginal wall, remove scar tissue, and suture the bladder incision with low or no tension way; ④To use great omentum; for patients with low, complex, and mixed bladder vaginal fistulas, recommend to use bladder wall flaps (6 cases), bladder enlargement (3 cases), and ureteral replantation (6 cases). The clinical data of the patients were collected, and a univariate analysis was performed on the cure rate.Results:The mean of blood boss and duration in operation were (33.3±26.5) ml and 85 (60-240) minutes. Mean of hospitalization was (11.3±8.2)days. The postoperative urinary indwelling time were (20.8±8.3)days. 50 cases were completed recovered and 4 cases failed, the curative ratio was 92.6% (50/54). It revealed that the curative ratio of vesicovaginal fistula repair had correlation with history of surgical interventions before operation. The curative effect was reduced ( P=0.00) when the patient had previous laparoscopic vesicovaginal fistula repairs. Patients with multiple fistulas (≥2) had a lower cure rate than single fistulas ( P=0.00). In addition, patients with fistulas above the triangle of the bladder had a higher cure rate than fistulas outside the triangle of the bladder and the urethra ( P=0.00). There was no statistically significant difference in the cure ratio of Age ( P=0.79), operation time ( P=0.06), intraoperative bleeding ( P=0.78), post-operative hospitalization ( P=0.73), indwelling catheterization time ( P=0.30), and size of fistula ( P=0.31). Conclusions:The operation could be effective with fewer complications procedure, which could fix mixed fistula and bladder contracture at the same time.

Objective To discuss the clinical application value of super selective renal artery embolization-assisted(SRAE-assisted)laparoscopic partial nephrectomy(LPN).Methods A retrospective analysis of the clinical data of patients with stage T1 renal carcinoma,who received LPN,was conducted.The patients were divided into SRAE group(performing LPN without adopting renal hilum vascular clamping)and VC group(performing LPN with adopting renal hilum vascular clamping).The time spent for operation,amount of intraoperative blood loss,and preoperative and postoperative renal functions were compared between the two groups.According to the warm ischemia time(WIT),the patients of the VC group were subdivided into WIT＜25 min subgroup and WIT≥25 min subgroup,and the preoperative and postoperative renal functions were compared between the two subgroups.Results A total of 59 patients with renal carcinoma were enrolled in this study,including 12 patients in SRAE group and 47 patients in VC group.In VC group,WIT＜25 min subgroup had 33 patients and WIT≥25 min subgroup had 14 patients.In both SRAE group and VC group,no patient was referred to open surgery or total nephrectomy.No patient in SRAE group was referred to traditional LPN.The time spent for operation in SRAE group and VC group was 100.50(73.75,132.50)min and 120.00(90.00,145.00)min respectively,the difference between the two groups was not statistically significant(P＞0.05).The postoperative estimated glomerular filtration rate(eGFR)in SRAE group was 100.56(82.85,106.81),which was remarkably higher than 84.66(70.84,94.85)in VC group(P＜0.05).The postoperative serum creatinine level in VC group was 90.50(77.10,104.90)μmol/L,which was strikingly higher than 72.24(65.97,80.27)μmol/L in SRAE group(P＜0.05).The amount of intraoperative blood loss in SRAE group was 50(50,50)mL,which was lower than 50(50,100)mL in VC group(P＜0.05).In VC group,the postoperative eGFR in WIT≥25 min subgroup was 66.13(47.08,82.50),which was lower than 90.80(77.18,98.78)in WIT＜25 min subgroup(P＜0.05).During the postoperative one-year follow-up,no recurrence was observed in both groups.Conclusion Compared with traditional LPN,SRAE-assisted LPN doesn't need to obstruct the renal hilus during surgery,which can avoid the ischemic impairment of the residual renal function and reduce the amount of intraoperative blood loss,moreover,it doesn't increase the operation time,doesn't increase the incidence of complications such as postoperative bleeding,etc.and doesn't affect the curative efficacy and patient's prognosis.

Objective:To investigate the safety and efficacy of laparoscopic simultaneous bilateral adrenalectomy in treating ectopic ACTH syndrome (ACTH)caused by medullary thyroid carcinoma(MTC).Methods:A 56-year-old male patient was admitted after MTC surgery and 7 months of general fatigue. The patient had a history of two open thyroid surgeries for medullary thyroid carcinoma, with previous pathological reports indicating lymph node metastasis in the upper mediastinum and mediastinum, accompanied by weak cytoplasmic expression of ACTH and negative CRH staining. After the operation, the patient developed diabetes, hypertension, and hypokalemia. Upon admission, the patient presented with a blood pressure reading of 200/95 mmHg (1 mmHg = 0.133 kPa), a weight of 61.5 kg, a height of 160 cm, a body mass index (BMI)of 24.02 kg/cm 2, and a waist circumference of 83 cm. Laboratory tests revealed the following: blood potassium level of 2.71 mmol/L, blood calcium level of 1.47 mmol/L, parathyroid hormone level of 6.0 pg/ml, fasting blood glucose level of 10.51 mmol/L, glycated hemoglobin level of 8.2%, blood calcitonin level exceeding 2 000 pg/ml, and blood CEA level of 70.8 μg/L. The plasma ACTH levels at 8∶00, 16∶00, and 24∶00 were 189.0, 125.0, and 65.0 pg/ml, respectively. Serum cortisol levels at 08∶00, 16∶00, and 24∶00 were 429.30, 408.14, and 446.61 μg/L, respectively. The 24-hour urine free cortisol measurement was 1 200 μg, and after the midnight 1mg dexamethasone suppression test at 8∶00, the plasma ACTH level was 183.0 pg/ml, and the serum cortisol level was 538.27 μg/L. The aldosterone level in standing position after 2 hours was 8.2 pg/ml. There were no significant abnormality in catecholamine hormone detection or thyroid function in blood and urine samples. An 18F-FDG-PET/CT examination showed multiple lymph node metastases in the neck, while an abdominal CT scan revealed bilateral adrenal hyperplasia. Enhanced MRI revealed pituitary gland thinning, and lung CT and sputum culture examinations showed scattered multiple lung infections. After a multidisciplinary discussion, the patient was diagnosed with EAS, postoperative MTC metastasis, diabetes, hypertension, hypokalemia, pulmonary infection, mild anemia, liver dysfunction, hypoparathyroidism, and hypocalcemia. The patient were accepted laparoscopic bilateral adrenalectomy via an abdominal approach under general anesthesia. The left adrenal gland was removed first, followed by the right adrenal gland after repositioning. Results:The surgery was successful with a surgical duration of approximately 60 minutes and an intraoperative bleeding volume of about 20 ml. No surgical complications occurred during the perioperative period. Pathological examination confirmed nodular hyperplasia of the adrenal cortex and bilateral adrenal medullary hyperplasia with negative ACTH staining. After a 3-month postoperative follow-up, blood calcitonin levels remained above 2000 pg/ml. The blood ACTH levels at 1 week, 1 month, and 3 months after surgery were 183.0, 220.0, and 731.0 pg/ml, respectively. However, hypertension, diabetes, and hypokalemia rapidly improved. One month after surgery, blood pressure was 100/80 mmHg, fasting blood glucose was 4.4 mmol/L, and blood potassium was 3.87 mmol/L. Pulmonary infection showed improvement, and no adrenal crisis occurred. Glucocorticoid replacement therapy consisted of 20 mg of hydrocortisone tablets in the morning and 10 mg in the afternoon, and thyroid hormone replacement therapy involved daily administration of 100 μg of levothyroxine. Genetic testing revealed heterozygous mutations in the Ret gene. The patient is currently undergoing clinical trial treatment with Ret inhibitors.Conclusions:Based on the data from this case and existing literature reports, laparoscopic simultaneous bilateral adrenalectomy might be safe and effective treatment option for EAS caused by unresectable MTC metastasis. It can correct hypertension, diabetes, and hypokalemia and increase the opportunity for MTC treatment.
