Meta-analysis of trials comparing laparoscopic transperitoneal and retroperitoneal adrenalectomy
Surgery, 2013
Background. Laparoscopic adrenalectomies are being performed increasingly, either with transperitoneal or retroperitoneal approaches. Studies comparing the 2 approaches have not shown the superiority of either technique, but these studies are limited by small sample sizes and single-institution designs. To overcome these limitations, we performed a meta-analysis of studies comparing lateral transperitoneal adrenalectomy and retroperitoneal adrenalectomy. Methods. A systematic review of studies comparing lateral transperitoneal adrenalectomy and retroperitoneal adrenalectomy was conducted. Study endpoints included perioperative outcomes and measures of postoperative recovery. Meta-analysis was performed using a random effects model, pooling variables evaluated by more than 3 studies. Results. Twenty-one studies comparing a total of 1,205 lateral transperitoneal adrenalectomies and 688 retroperitoneal adrenalectomies were suitable for meta-analysis. Patients in the 2 groups were similar in term of age, sex, body mass index, lesion size and location, and rates of malignancy. There were no statistically significant differences between lateral transperitoneal adrenalectomy and retroperitoneal adrenalectomy in terms of operative time, blood loss, hospital stay, time to oral intake, overall and major morbidity, and mortality. Conclusion. Both lateral transperitoneal adrenalectomy and retroperitoneal adrenalectomy are associated with very low rates of perioperative complications. According to our meta-analysis, clinical outcomes after either technique are similar. For most adrenal lesions requiring operation, minimally invasive adrenalectomy can be performed safely and effectively with either transperitoneal or the retroperitoneal approach. Additional studies may be needed to analyze if any difference in long-term results exist. (Surgery 2013;153:111-9.)
Systematic review and meta-analysis of retroperitoneoscopic versus laparoscopic adrenalectomy
British Journal of Surgery, 2012
Background: Laparoscopic adrenalectomy (LA) has replaced open adrenalectomy as the standard operation for non-malignant adrenal tumours. Retroperitoneoscopic adrenalectomy (RA) is an increasingly popular alternative minimally invasive approach. Advocates of each technique claim its superiority, but the issue has yet to be resolved and conclusions are complicated by the existence of a lateral (LRA) and true posterior (PRA) RA.
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 2,660 patients from 11 different countries and 69 different hospitals were analyzed and 1,696 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 b...

Background Different techniques for laparoscopic adrenalectomy have been proposed with the lateral transperitoneal approach and posterior retroperitoneal approach being the two more frequently minimally invasive surgeries in most of the clinics. There are no sufficient studies in which the results of lateral transperitoneal and posterior retroperitoneal approaches in synchronous bilateral laparoscopic adrenalectomy have been compared. In the current study, we aimed to report our multicenter results of the lateral transperitoneal and posterior retroperitoneal synchronous bilateral laparoscopic adrenalectomy experience in patients who had different bilateral adrenal pathologies and to compare the outcomes of these two different operative procedures. Methods Between 2012 and 2018, a total of 52 patients with a mean age of 43.5 years underwent simultaneous bilateral laparoscopic adrenalectomy at 6 different centers. Twenty-seven and 25 patients underwent bilateral lateral transperitoneal and posterior retroperitoneal laparoscopic adrenalectomy, respectively. Patients' age, gender, body max index, operative indications, mass size, operation time, blood loss, length of hospitalization, intraoperative and postoperative complications and pathology reports were analyzed. Results Synchronous bilateral transperitoneal group was younger than synchronous posterior retroperitoneal group (37 years vs. 50.4 years.) (p: 0.001). Posterior retroperitoneal group had significantly decreased operating time and less blood loss than transperitoneal group. No significant difference was found with regard to postoperative hospital stay, perioperative and postoperative complications between two groups. Majority of the histopathological results were adrenal hyperplasia associated with Cushing's disease (61.5%). Less frequent pathological results were adrenal adenoma and pheochromocytoma (15.4% and 13.5%, respectively). During the follow-up period, no recurrence or disease-related mortality was observed in the patients. Conclusion Our results shows that shorter operative time and less bleeding can be achieved with posterior retroperitoneal approach in synchronous bilateral laparoscopic adrenalectomy. In our series, intraoperative and postoperative complication rates were similar between both surgical approaches.

Background: Laparoscopic retroperitoneal (RP) adrenalectomy has gained popularity as the preferred approach over transabdominal (TA) method; however, surgeons have been reluctant to offer this operation to obese patients because of the concerns over inadequate working space and overall perceived higher rate of complications. The aim of the present study was to evaluate the feasibility and safety of RP adrenalectomy compared with TA adrenalectomy, specifically in morbidly obese patients. Methods: All laparoscopic adrenalectomies performed at our institution between 2004 and 2012 were reviewed retrospectively. Presenting features, operative characteristics, and postoperative outcomes were evaluated. Complications were graded using Clavien system. Continuous variables were compared using Student t-test. Categorical variables were compared using c 2 -test. Prediction models were constructed using linear or logistic regression as appropriate.
Retroperitoneal Versus Transperitoneal Laparoscopic Adrenalectomy in Adrenal Tumor
Surgical Laparoscopy, Endoscopy & Percutaneous Techniques, 2013
Background: The study aims to provide a pooled meta-analysis of existing studies that compare the outcomes of retroperitoneal laparoscopic adrenalectomy with transperitoneal approach for adrenal tumor. Methods: A systematic search of electronic databases was performed and studies were selected based on specific inclusion and exclusion criteria. Data of interest were subjected to meta-analysis using randomized or fixed-effect model to calculate weight mean difference (WMD) or odds ratio (OR). The sensitivity analysis and publication bias test also be conducted. Results: Nine observational studies with 632 patients were identified (339 retroperitoneal vs. 293 transperitoneal). Retroperitoneal approach was associated with shorter operative time [WMD = À 13.10; 95% confidence interval (CI), À 23.83 to À 2.36; P = 0.02], less intraoperative blood loss (WMD = À 40.60; 95% CI, À79.73 to À1.47; P = 0.04), shorter duration of hospital stay (WMD = À1.25; 95% CI, À 2.36 to À0.14; P = 0.03), or time to first ambulation (WMD = À0.

Minimally invasive adrenalectomy (MIA) is both feasible and safe with either transperitoneal or retroperitoneal entry. However, only a few studies have rigorously compared these two techniques. The aim of the current study is to compare transperitoneal and retroperitoneal adrenalectomy to detect significant differences in patient selection and perioperative outcomes. Between 1995 and 2009, 171 patients underwent MIA through transperitoneal (n 5 127) or retroperitoneal access (n 5 44). The respective cohorts were then examined retrospectively through matched and unmatched comparisons. Multivariate analyses of intraoperative blood loss, postoperative morbidity, and length of hospital stay were performed. Surgical indications were benign lesions (70.2%), malignant tumors (11.1%), and pheochromocytomas (18.7%). The postoperative morbidity rate was 15.8 per cent, but mortality was null. The rate of conversion to open surgery was 5.3 per cent. Blood loss and operative time were significantly lower with the transperitoneal approach, whereas time to oral intake was shorter for the retroperitoneal group. Tumor size less than 4.5 cm was associated with less blood loss, shorter hospital stay, and lower postoperative morbidity. Laparoscopic and retroperitoneal routes are both effective and safe for excising adrenal lesions. In the present study, however, laparoscopic adrenalectomy demonstrated shorter operative times with less blood loss. Regardless of this, we remain cautious in recommending one procedure preferentially. Other important measures of clinical outcome such as required pain control, ease of patient recovery, and cost considerations were not included in this analysis. Further randomized trials, with large patient numbers, are therefore desirable for defining an optimal surgical method.

There has been an increased utilization of the posterior retroperitoneal approach (PRA) for adrenalectomy alongside the "classic" laparoscopic transabdominal technique (LTA). The aim of this study was to compare both procedures based on outcome variables at various ranges of tumor size. A retrospective analysis was performed on 204 laparoscopic transabdominal (UMC Groningen) and 57 retroperitoneal (UMC Utrecht) adrenalectomies between 1998 and 2013. We applied a univariate and multivariate regression analysis. Mann-Whitney and chi-squared tests were used to compare outcome variables between both approaches. Both mean operation time and median blood loss were significantly lower in the PRA group with 102.1 (SD 33.5) vs. 173.3 (SD 59.1) minutes (p < 0.001) and 0 (0-200) vs. 50 (0-1000) milliliters (p < 0.001), respectively. The shorter operation time in PRA was independent of tumor size. Complication rates were higher in the LTA (19.1%) compared to PRA (8.8%). There wa...
Laparoscopic adrenalectomy: transperitoneal vs retroperitoneal approaches
Biomedicine & Pharmacotherapy, 2000
Laparoscopic adrenalectomy (LA) has become the gold standard in the operative approach to tumors of the adrenal gland. It has been 20 years since it was first described in the literature and the technique has afforded improved operative and perioperative outcomes compared to the open approach to the adrenal gland. These include improved cosmesis, less post-operative pain, and reduced morbidity, and have allowed patients to be discharged from hospital earlier and return to normal activity. LA has been proven to be safe and effective when dealing with functioning and non-functioning adrenal incidentalomas, pheochromocytoma, and Cushing's and Conn's syndrome, and has even been used for primary and secondary adrenal malignancies. Here, we describe the laparoscopic transperitoneal approach to the adrenal gland and its evolution since its inception.

To evaluate the therapeutic effect of single-plane retroperitoneoscopic adrenalectomy. From February 2014 to March 2017, 251 patients underwent single-plane retroperitoneoscopic adrenalectomy, and their operative outcomes were compared with those of 98 patients who underwent anatomical three-plane retroperitoneoscopic adrenalectomy. Among 35 patients with a body mass index (BMI) of ≥30 kg/m, their operative outcomes were compared between two operative procedures. The demographic data and perioperative outcomes of the patients were statistically analysed. The single-plane and three-plane groups were comparable in terms of estimated blood loss, time to oral intake, hospital stay, and incidence of complications among patients with similar baseline demographics. The single-plane group had a significantly shorter operation time (46.9 ± 5.8 vs 54.8 ± 7.0 mins, P < 0.0001) and lower analgesia requirement (56/251 vs 33/98, p = 0.03). For obese patients with a BMI of ≥30 kg/m, single-plan...
