Robot Assisted Laparoscopic Adrenalectomy: Does Size Matter?

Effectiveness of Robot-assisted Adrenalectomy for a Giant Adrenal Hemangioma: A Case Report

BACKGROUND

Adrenal hemangiomas are extremely rare benign tumors that often need to be distinguished from malignancies. Adrenal tumors >4 cm in size are treated surgically because the possibility of malignancy cannot be ruled out. Traditionally, open surgery has been the mainstay of treatment; however, in recent years, robot-assisted surgery has been increasingly used for tumors of larger size and suspected malignancy. Here, we report a case of robot-assisted adrenalectomy for an 11 cm adrenal hemangioma.

CASE REPORT

A 62-year-old male with lateral abdominal pain was referred to our hospital for further examination and treatment. His medical history was significant for hypertension, diabetes, and dyslipidemia. Computed tomography revealed an 11 cm left adrenal tumor, and all endocrinological screening tests were negative. Because the possibility of malignancy could not be ruled out, a robot-assisted adrenalectomy was performed. The operation time was 129 min, and the estimated blood loss was 7 ml. Pathological findings revealed an adrenal hemangioma. The postoperative course was uneventful, and patient's condition subsequently improved postoperatively.

CONCLUSION

Robot-assisted adrenalectomy was performed for a giant adrenal hemangioma without any complications. Robotic surgery is useful for resecting adrenal hemangiomas even exceeding 11 cm in diameter.

Outcomes of Minimally Invasive Adrenalectomy for Large Adrenal Masses: A Multi-Centre Experience in Saudi Arabia

Introduction Advancements in radiological imaging technology have increased the discovery of adrenal incidentalomas. Large adrenal tumors (LATs) are not common, and the likelihood of malignancy increases with tumor size. LATs were defined as tumors larger than four centimeters (cm) with various pathologic diagnoses. Traditionally, open adrenalectomy was considered the gold standard for LATs, but with recent advancements in minimally invasive surgery (MIS), optimum perioperative and long-term outcomes are achievable by the MIS approach. The findings presented in this paper show that even large adrenal masses measuring up to 21 centimeters can be safely removed using a minimally invasive approach. Methodology After Institutional Review Board (IRB) approval, we reviewed medical records of adult patients who had adrenalectomies at two Saudi Arabian centers from January 2013 to February 2023. Inclusion criteria were laparoscopic or robotic adrenalectomy and adrenal lesions ≥5cm. Pediatric patients and those with open adrenalectomies were excluded. Pre-surgery, patients had imaging studies to assess mass characteristics. Pheochromocytoma patients received a 2-week adrenergic blocker treatment. Perioperative data including demographics, comorbidities, mass characteristics, surgery details, and follow-up were analyzed using SPSS-23. Patients provided informed consent and had follow-up appointments and imaging. Results Our experience involved 35 patients, 29 of whom received laparoscopic treatment and six of whom underwent robotic surgery. Of the 35 patients, more than half were females (57.1%), with a mean age of 41.7±14.9 years, the youngest and oldest participants being 16 and 73 years of age, respectively. The mean body mass index (BMI) of the participants was in the overweight range (26±6.0 kg/m2). The most common mode of presentation was incidental (42.9%), followed by hypertension (17.1%). Most patients had right-sided adrenal gland involvement (48.6%), with only four patients showing bilateral involvement. Most of the patients were classified as American Society of Anesthesiology score (ASA) 2 (40.0%) or ASA 3 (40.0%). Most of the patients were diagnosed with myelolipoma or adenoma (22.9% each) followed by pheochromocytoma (17.1%). The average estimated blood loss (EBL) was 189.3±354.6 ml for patients who underwent laparoscopic surgery and 80.0 ±34.6 ml for patients who underwent robotic surgery. The average operative room time (ORT) was 220.1±98.7 minutes (min) for laparoscopic surgery and 188.3±10.3 min for robotic surgery. One patient had to be converted from laparoscopic to open surgery due to aortic injury. The average length of stay (LOS) was 9.5±6.7 days for laparoscopic treatment and 5.5±1.9 days for robotic surgery. The mean tumor size in the greatest dimension was 8.0±4.4 cm. Only one patient who underwent unilateral laparoscopy experienced perioperative complications and converted to open surgery; nine patients who underwent unilateral laparoscopy required blood transfusion, and none of the patients who underwent robotic surgery required transfusion. None of the 35 patients experienced a recurrence of their adrenal disease during the mean follow-up period which lasted around 58 months. Conclusion MIS in Saudi Arabia is growing and is a safe method for LATs, with satisfactory surgical results compared to the traditional open surgery approach. It offers advantages in terms of EBL, complications, and disease recurrence.

Effectiveness of continuity of care after robot-assisted laparoscopic adrenalectomy under ambulatory mode: a single-center intervention study

To investigate the effectiveness of continuity of care after robot-assisted adrenal tumor resection under ambulatory mode. Patients who underwent robot-assisted laparoscopic adrenalectomy (RALA) in the ambulatory surgery department and urology department of our hospital from January 2022 to January 2023 were selected as study subjects. Among them, 50 patients in the Department of Urology as the control group were given routine care. The 50 patients in the ambulatory surgery department as the observation group were given continuity of care on the basis of routine care. Observation indexes include: wound healing, blood pressure, blood potassium, renal function impairment, self-care ability in daily life, medication compliance, follow-up rate, and patient satisfaction. There were no remarkable discrepancies between the two groups in terms of demographic data and basic preoperative conditions of the patients. Compared with the control group, the observation group significantly improved the patients' wound healing, postoperative blood pressure and blood potassium and kidney function (P value all < 0.05). Compared with the control group, the observation group significantly improved postoperative patients' ADL scores, follow-up rates within three months after surgery, and patient satisfaction scores (P value all < 0.05). For patients receiving ambulatory mode robot-assisted laparoscopic adrenalectomy, continuity of care can effectively reduce postoperative complications, improve patients' postoperative self-care ability in daily life, medication compliance and follow-up rate, and improve patient satisfaction, which is worthy of promotion and application by nursing workers.

Posterior retroperitoneal versus transperitoneal laparoscopic adrenalectomy in adults: results from the EUROCRINE® surgical registry

PURPOSE

This study aims to compare posterior retroperitoneal laparoscopic adrenalectomy (PRLA) and laparoscopic transperitoneal adrenalectomy (LTA) in adults using pan-European data as conflicting results have been published regarding length of hospital stay, institutional volume, and morbidity.

METHODS

This retrospective cohort study analyzed data from the surgical registry EUROCRINE®. All patients undergoing PRLA and TLA for adrenal tumours and registered between 2015 and 2020 were included and compared for morbidity, length of hospital stay, and conversion to open surgery.

RESULTS

A total of 2660 patients from 11 different countries and 69 different hospitals were analyzed and 1696 LTA were compared to 964 PRLA. Length of hospital stay was shorter after RPLA, with less patients (N = 434, 45.5%, vs N = 1094, 65.0%, p < 0.001) staying more than 2 days. In total, 96 patients (3.6%) developed a complication Clavien-Dindo grade 2 or higher. No statistical difference was found between both study groups. After propensity score matching, length of hospital stay was shorter after PRLA (> 2 days 45.2% vs 63.0%, p < 0.001). After multivariable logistic regression, factors associated with morbidity were age (OR 1.03), male sex (OR 1.52), and conversion to open surgery (OR 5.73).

CONCLUSION

This study presents the largest retrospective observational analysis comparing LTA and PRLA. Our findings confirm the shorter length of hospital stay after PRLA. Both techniques are safe leading to comparable morbidity and conversion rates.

Nursing effect of continuous nursing intervention based on "Internet Plus" on patients with severe adrenal tumor

Adrenal tumors are a common type of tumor whose incidence increases with age. This study aims to apply the continuous nursing mode of "Internet Plus" to patients with severe adrenal tumors, and preliminarily evaluate the nursing effect of continuous nursing intervention based on "Internet Plus" on patients with severe adrenal tumors. A single-center, retrospective, observational study was carried out on severe adrenal tumor patients. A total of 128 patients admitted to our hospital from June 2020 to August 2021 were selected and divided into 2 groups: the observation group (n = 64) received routine care and the control group (n = 64) received continuing care based on "Internet Plus." The first time to get out of bed, 72 hours postoperative sleep time, 72 hours postoperative visual analog scale score, hospital length of stay, upper limb swelling to subside time, self-rating anxiety scale, Symptom Checklist-90, quality of life scores, and self-rating depression scale of cancer patients were compared between the 2 groups. T test and χ2 test were used for statistical analysis. The first time to get out of bed (t = 10.64, 95% confidence interval [CI] = 5.32-16.53, P < .001), upper limb swelling to subside time (t = 16.50, 95% CI = 7.21-26.15, P < .001) and the length of hospital stay (t = 11.82, 95% CI = 5.61-17.95, P < .001) were significantly shorter, 72 hours postoperative sleep time (t = 9.46, 95% CI = 4.93-15.48, P < .001) was significantly longer, and the visual analog scale score of 72 hours after operation (t = 15.95, 95% CI = 7.32-24.09, P < .001) was significantly lower in the observation group than that in the control group. After receiving nursing intervention, the scores of somatization (t = 17.56, 95% CI = 9.51-27.96, P < .001), anxiety (t = 21.85, 95% CI = 12.35-33.71, P < .001), depression (t = 18.29, 95% CI = 9.63-28.22, P < .001), self-rating anxiety scale (t = 33.67, 95% CI = 19.65-46.13, P < .001), self-rating depression scale (t = 31.92, 95% CI = 20.73-45.88, P < .001), and the quality of life score (t = 21.54, 95% CI = 8.92-40.37, P < .001) were significantly lower, and the positive coping (t = 16.30, 95% CI = 5.15-18.14, P < .001) and negative coping (t = 20.54, 95% CI = 9.34-33.12, P < .001) scores were significantly higher in the observation group than those in the control group. Nursing intervention based on "Internet Plus" continuous mode can promote the recovery of physical function, reduce psychological pressure and negative emotions, and then improve the quality of life of severe adrenal tumor patients.

Postoperative outcomes of minimally invasive adrenalectomy: do body mass index and tumor size matter? A single-center experience

Background

Since Gagner performed the first laparoscopic adrenalectomy in 1992, laparoscopy has become the gold-standard procedure in the treatment of adrenal surgical diseases. A review of the literature indicates that the rate of intra- and postoperative complications are not negligible. This study aims to describe the single-center experience of adrenalectomies; and explore the associations between body mass index (BMI) and tumor volume in main postoperative outcomes.

Methods

Retrospective observational study with a prospective database in which we described patients who underwent adrenalectomy between January 2015 and December 2020. Operative time, intraoperative blood loss, conversion rate, complications, length of hospital stay, and comparison of the number of antihypertensive drugs used before and after surgery were analyzed. Analysis of BMI and tumor volume with postoperative outcomes such as anti-hypertensive change (AHC) in drug usage and pre-operative conditions were performed.

Results

Forty-five adrenalectomies were performed, and all of them were carried out laparoscopically. Four were performed as a robot-assisted laparoscopy approach. Nineteen were women and 26 were men. Mean age was 54.9 ± 13.8 years. Mean tumor volume was 95.698 mm³ (3.75–1010.87). Mean operative time was shorter in right tumors (2.64 ± 0.75 h) than in left tumors (3.33 ± 2.73 h). Pearson correlation was performed to assess the relationship between BMI and AHC showing a direct relationship between increased BMI and higher change in anti-hypertensive drug usage at postoperative period r(45) = 0.92, p > 0.05 CI 95%. Higher tumor volume showed a longer operative time, r(45) = 0.6 (p = 0.000 CI 95%).

Conclusions

Obese patients could have an increased impact with surgery with an increased change in postoperative anti-hypertensive management. Tumor volume is associated with increased operative time and blood loss, our data suggest that it could be associated with increased rates of morbidity. However, further prospective studies with larger sample sizes are needed to validate our results.

Initial Experience of Robot-Assisted Adrenalectomy in Japan: What is the Optimal Selection of Robotic Forceps for Adrenalectomy?

Minimally invasive adrenalectomy is the preferred technique for managing adrenal tumors. Laparoscopic adrenalectomy is widely performed and covered by insurance in Japan, but robot-assisted adrenalectomy is not. To investigate the best forceps combinations for performing robot-assisted adrenalectomy safely, we performed robot-assisted adrenalectomy for two left and two right adrenal adenomas using different robotic forceps combinations (bipolar forceps, monopolar curved scissors, Vessel Sealer Extend, and SynchroSeal) for each case. Although we evaluated a small number of RAs, lower blood loss was observed in patients where the vessel sealing devices were used. The extent of dissection is small for adrenalectomy, and robotic bipolar vessel sealing tools may not be necessary, especially for the small adrenal tumors. However, considering the risk benefits, the combination of forceps with Vessel Sealer Extend (by the left arm) and monopolar curved scissors (by the right arm) will become one of the best forceps combinations for performing robot-assisted adrenalectomy safely.
