The Impact of Body Mass Index on Perioperative Outcomes of Robotic Adrenalectomy: An Update

Background. Robotic surgery has gained increasing popularity over the past 2 decades. However, factors including patient comorbidities and tumor characteristics are still crucial factors for outcomes of surgery. In this study, we evaluated the impact of body mass index (BMI) on perioperative outcomes in patients who underwent robotic adrenal surgery. Methods. Between May 2012 and November 2017, 66 consecutive patients who underwent robotic adrenalectomy were included in this study. Patients were divided into 2 groups based on their BMI: nonobese (<30 kg/m2) and obese (≥30 kg/m2). Additionally, patient demographics, tumor size, total operative time, docking time, console time, estimated blood loss, conversion to open, complications, additional analgesia requirement, length of hospital stay, and rough costs were evaluated. Results. Of the 66 patients, a total of 26 patients were obese (30%). Between study groups, the median BMI was calculated as 26 (18-29) and 33 (30-57). The groups were similar in terms of age, gender, American Society of Anesthesiologists scores, and previous history of abdominal surgery. Likewise, there were no significant differences between groups regarding total operative time ( P = .085), docking time ( P = .196), console time ( P = .211), estimated blood loss ( P = .180), complications ( P = .991), length of hospital stay ( P = .598), and rough costs ( P = .468). Five cases were converted to open surgery. Nonobese cases required additional analgesia ( P = .007). We had no unexpected hospitalizations in either group. Conclusion. Guidelines express the advantages of robotic surgery in obese patients. No statistically significant differences were detected between the 2 groups except for the additional analgesia required in nonobese patients.

The Impact

Retroperitoneoscopic adrenalectomy (RA) provides a direct approach to the adrenal gland. RA represents a complex approach with unique orientation that is less intuitive. The authors objectively evaluated the impact of mentorship on the performance of RA and also compared it with laparoscopic adrenalectomy (LA). After implementing the use of RA, a retrospective review of the operative experience of two high-volume endocrine surgeons was performed. Both surgeons participated in a hands-on RA mentorship. Clinical presentation and perioperative outcomes were compared. Subgroup analysis was used to compare RA pre- and postmentorship and with LA. Sixty-one LAs and 31 RAs were included in the analysis. The mean operative time was 115 for LA versus 90 minutes for RA ( P = 0.002). Blood loss was greater for LA versus RA (56 vs 22 mL; P = 0.001). Length of stay (LOS) for LA was 2.2 versus 1.5 days for RA ( P = 0.029). Ten patients were treated by RA in the prementorship era versus 21 in the postmentorship era. The mean operative time for the prementorship group was 118 minutes, which decreased to 77 minutes postmentorship ( P < 0.0001). LOS also decreased from 2.0 to 1.2 days ( P = 0.04) in the postmentorship era. RA demonstrates a shorter operative time, less blood loss, and decrease length of hospital stay as compared with standard LA. After proper mentorship and patient selection, RA may represent a superior option for removal of small, benign adrenal tumors.

Introduction: We sought to evaluate the association of obesity with surgical outcomes of robotic partial nephrectomy (RPN) using a large, multicentre database. Methods: We identified 1836 patients who underwent RPN from five academic centres from 2006-2014. A total of 806 patients were obese (body mass index [BMI] ≥30 kg/m2). Patient characteristics and outcomes were compared between obese and non-obese patients. Multivariable analysis was used to assess the association of obesity on RPN outcomes.Results: A total of 806 (44%) patients were obese with median BMI of 33.8kg/m2. Compared to non-obese patients, obese patients had greater median tumour size (2.9 vs. 2.5 cm, p<0.001), mean RENAL nephrometry score (7.3 vs. 7.1, p = 0.04), median operating time (176 vs. 165 min, p=0.002), and median estimated blood loss (EBL, 150 vs. 100 ml, p=0.002), but no difference in complications. Obesity was not an independent predictor of operative time or EBL on regression analysis. Among obese patients, males had a greater EBL (150 vs. 100 ml, p<0.001), operative time (180 vs. 166 min, p<0.001) and warm ischemia time (WIT, 20 vs. 18, p=0.001) and male sex was an independent predictor of these outcomes on regression analysis.Conclusion: In this large, multicentre study on RPN, obesity was not associated with increased complications and was not an independent predictor of operating time or blood loss. However, in obese patients, male gender was an independent predictor of greater EBL, operative time, and WIT. Our results indicate that obesity alone should not preclude consideration for RPN.

Objectives. The warm ischemia time (WIT) is key to successful laparoscopic partial nephrectomy (LPN). The aim of this study was to perform a meta-analysis comparing the self-retaining barbed suture (SRBS) with a non-SRBS for parenchymal repair during LPN. Methods. A systematic search of PubMed, Scopus, and the Cochrane Library was performed up to March 2018. Inclusion criteria for this study were randomized controlled trials (RCTs) and observational comparative studies assessing the SRBS and non-SRBS for parenchymal repair during LPN. Outcomes of interest included WIT, complications, overall operative time, estimated blood loss, length of hospital stay, and change of renal function. Results. One RCT and 7 retrospective studies were identified, which included a total of 461 cases. Compared with the non-SRBS, use of the SRBS for parenchymal repair during LPN was associated with shorter WIT ( P < .00001), shorter overall operative time ( P < .00001), lower estimated blood loss ( P = .02), and better renal function preservation ( P = .001). There was no significant difference between the SRBS and non-SRBS with regard to complications ( P = .08) and length of hospital stay ( P = .25). Conclusions. The SRBS for parenchymal repair during LPN can significantly shorten the WIT and overall operative time, decrease blood loss, and preserve renal function.

Objective. To evaluate operative and perioperative outcomes in patients undergoing total laparoscopic hysterectomy according to their body mass index. Method. A retrospective study was performed for patients undergoing total laparoscopic hysterectomy at a tertiary care center for a period of 4 years. Patients were divided into two groups: obese (BMI > 30 Kg/m2) and nonobese (BMI < 30 Kg/m2). Duration of surgery, intraoperative blood loss, successful laparoscopic completion, and intraoperative complications were compared in two groups. Result. A total of 253 patients underwent total laparoscopic hysterectomy from January 2010 to December 2013. Out of them, 105 women (41.5%) had a BMI of more than 30 kg/m2. Overall, the mean blood loss was 85.79 ± 54.17 mL; the operative time was 54.17 ± 19.83 min. The surgery was completed laparoscopically in 244 (96.4%) women while laparotomy was done in 4 cases and vaginal suturing and closure of vault were done in 5 cases. Risk of vaginal assistance was higher in obese patients whereas out of the 4 conversions to laparotomy 3 had BMI < 30 kg/m2. The operative time was increased as the BMI of patient increased. Conclusions. Total laparoscopic hysterectomy is a safe and effective procedure for obese patients and can be performed with an efficacy similar to that in nonobese patients.

The Impact

Introduction: Obesity is usually considered a risk factor for postoperative complications; however, previous studies conclude contradictory results in retroperitoneal laparoscopic adrenalectomy (LA). We aim to evaluate the impact of obesity on the perioperative outcomes of LA. Methods: A retrospective cohort study from a single center including 353 patients from 2011 to 2013 was conducted. Perioperative outcomes of patients from different groups were compared according to their body mass index (BMI). Results: All the patients were divided into 3 groups: normal (n = 149), overweight (n = 141) and obese (n = 63). Operative time (OT) for patients belonging to the obese group was significantly longer than that in the normal and overweight group, and the results of estimated blood loss, postoperative length of stay in hospital and postoperative complications were all similar. In the multivariate logistic regression analysis, OT was an independent risk factor for postoperative complications (odds ratio 1.020; 95% confidence interval 1.001-1.039; p = 0.037), while other factors including BMI had negligible effect. Conclusions: Retroperitoneal LA offers similar perioperative outcomes for patients with different obesity statuses, which could be safe and feasible for obese patients.

Simple Prostatectomy

Introduction: We aimed to assess the outcome of our series of simple prostatectomy using the open simple prostatectomy (OSP) and robotic-assisted simple prostatectomy (RASP) approaches, at our institution. Methods: A retrospective chart review of men who underwent OSP and RASP at Western University, in London, ON. Preoperative, intraoperative, and postoperative data were collected and analyzed. Results: From 2012–2020, 29 men underwent a simple prostatectomy at our institution. Eight patients underwent an OSP and 21 patients underwent a RASP. The median age was 69 years. Preoperative median prostate volume was 153 cm3 (range 80–432 cm3). The surgical indications were failed medical treatment, urinary retention, hydronephrosis, cystolithiasis, and recurrent hematuria. The median operative time was 137.5 minutes in OSP and 185 minutes in the robotic approach (p=0.04). Median estimated blood loss was 2300 ml (range 600–4000 ml) and 100 ml (range 50–400 ml) in the open and robotic procedures, respectively (p=0.4). The mean length of hospital stay was shorter in the RASP group, one day vs. three days (z=4.152, p<0.005). Perioperative complication rates were significantly lower in the group undergoing RASP, with no complications recorded in this group (p=0.004). Both groups demonstrated excellent functional results, with most patients reporting complete urinary continence (p=0.8). Conclusions: We report very good perioperative outcomes, with a minimal risk profile and excellent functional results, leading to marked improvement in patients' symptoms at followup after both the OSP and RASP approaches. RASP was associated with a shorter length of hospital stay, decreased blood loss, and a lower complication rate.

Objectives: To analyze the impact of the bedside assistant’s experience during RARP. It is believed that the outcome of robotic surgery during Robot Assisted Radical Prostatectomy (RARP) for prostate cancer depends not only on the console surgeon’s experience. Materials and Methods: All consecutive RARPs from January 2017 to March 2018 were sourced from a prospectively maintained database. All cases were performed by the same surgeon. He was supported by three bedside assistants: one with bedside and console experience, one only with relevant bedside experience, one basically inexperienced. The patient’s parameters analyzed: age, Body Mass Index (BMI), previous abdominal surgery, prostate volume (by TRUS), pre-operative PSA, bioptic grading. Surgical outcomes analyzed included skin-to-skin operative time and estimated blood loss; clinical outcomes included length of hospital stay and time to catheter removal; the oncological outcome was represented by positive surgical margin rate. Results: A total of 116 RARPs were identified: 38 RARPs were performed with the console experienced bedside assistant, 38 with the experienced one, 40 with the novice one. The variables were similar between the three groups. As far as outcomes are concerned, there were no statistically significant differences between the three bedside assistants in terms of operative time, estimated blood loss, length of stay, days of catheterization, positive surgical margin rate.

Posterior Retroperitoneoscopic Adrenalectomy

ObjectiveTo discuss the differences in the effectiveness and security for adrenal tumors by posterior retroperitoneoscopic adrenalectomy (PRA) and lateral transperitoneal laparoscopic adrenalectomy (LTA).MethodsWe systematically searched PubMed, Embase, Scopus database and Cochrane Library, and the date was from above database establishment to November 2020. Stata 16 was used for calculation and statistical analyses.ResultsNine studies involving eight hundred patients were included. The following differences were observed in favor of PRA vs LTA: less operative time (MD: −22.5; 95% CI −32.57 to −12.45; P=0.000), Fewer estimated blood loss (MD: −15.17; 95% CI −26.63 to −3.72; P=0.009), lower intensity of postoperative pain (MD: −0.56; 95% CI, −1.05 to −0.07; P=0.026), shorter length of hospital stay (MD: −1.15; 95% CI −1.94 to −0.36; P=0.04). No differences were shown in conversion rate (OR 2.07; 95%CI 0.71 to 6.03; P=0.181) and complications (OR 0.85;95% CI 0.46 to 1.56; P=0.597).ConclusionsPosterior retroperitoneoscopic adrenalectomy was clinically superior to lateral transperitoneal laparoscopic adrenalectomy for adrenal tumors in operative time, estimated blood loss, length of hospital stay, and postoperative pain. Only in term of conversion rate and complications, both were similar

Objective: To report and compare the peri-operative outcomes of patients undergoing open (ORC) and robotic-assisted radical cystectomy (RARC) for bladder cancer performed with a radiofrequency seal and cut device (Caiman®). Materials and Methods: Data of patients undergoing ORC or RARC between January 2015 and March 2016 at 6 Italian institutions were prospectively recorded and analyzed. Thirty-and 90-day complications were stratified according to the Martin's criteria and graded according to the Clavien-Dindo classification. Data on operative time, blood loss, transfusion rate, complications, and length of stay were evaluated and compared between the ORC and RARC groups. Results: Thirty-three (66%) and 17 (34%) patients were treated with ORC and RARC, respectively. The median age was 72 (64-78) years. Overall operative time was longer in RARC compared to ORC (389 ± 80.1 vs. 242 ± 62.2 min, p < 0.001), while the estimated blood loss during cystectomy was higher after ORC (370 ± 126.8 vs. 243.3 ± 201.6 ml, p = 0.03). The transfusion rate was significantly higher in the ORC compared to RARC (24.2 vs. 5.9%, p = 0.04). Eight (19%) and 7 (16.7%) patients experienced 30- and 90-day post-operative complications, with no significant difference between ORC and RARC. Length of stay was significantly shorter in RARC group (median 7 vs. 14 days, p < 0.001). Conclusion: Open and robot-assisted procedures were safely performed by using a new advanced bipolar seal and cut technology (Caiman®). RARC demonstrated to be superior to ORC in terms of bleeding, transfusion rates and length of hospital stay, despite longer operative time.
