<b><i>Introduction:</i></b> Obesity is usually considered a risk factor for surgical complications. Laparoscopic adrenalectomy has replaced open adrenalectomy as the standard operation for adrenal tumors. <b><i>Objective:</i></b> To compare the safety of laparoscopic adrenalectomy to treat adrenal tumors in obese versus nonobese patients. <b><i>Methods:</i></b> This observational cohort study analyzed consecutive patients who underwent laparoscopic adrenalectomy with a lateral transperitoneal approach at a single center (2003–2020). Data and outcomes of obese (body mass index ≥30 kg/m<sup>2</sup>) and nonobese patients were compared. To analyze the association between operative time and other variables, we used simple and multivariate linear regression. <b><i>Results:</i></b> <i>N</i> = 160 (90 obese/70 nonobese) patients underwent laparoscopic adrenalectomy. Cushing syndrome and pheochromocytoma were the most frequent indications. Obese patients were older (58 vs. 52 years, <i>p</i> &#x3c; 0.001). A greater proportion of obese patients were ASA grade III + IV (71.1 vs. 48.6%, <i>p</i> = 0.004). Obesity was associated with a longer operative time (72.5 vs. 60 min, <i>p</i> &#x3c; 0.001) and greater blood loss (40 vs. 20 mL, <i>p</i> = 0.022). There were no differences in conversion, morbidity, or hospital stay. After adjustment for confounding factors, operative time was positively correlated with BMI ≥30 kg/m<sup>2</sup>, learning curve, estimated blood loss, 2D laparoscopy, and specimen size. <b><i>Conclusion:</i></b> Lateral transperitoneal laparoscopic adrenalectomy is safe in patients with a BMI 30–35 kg/m<sup>2</sup>, so these patients also benefit from this minimally invasive surgery.

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

Abstract Background To compare the perioperative outcomes of transperitoneal laparoscopic (TLA), retroperitoneal laparoscopic (RLA), and robot-assisted transperitoneal laparoscopic (RATLA) adrenalectomy for adrenal tumors in our center. Methods Between April 2012 and February 2018, 241 minimally invasive adrenalectomies were performed. Cases were categorized based on the minimally invasive adrenalectomy technique. Demographic characteristics, perioperative information and pathological data were retrospectively collected and analyzed. Results This study included 37 TLA, 117 RLA, and 87 RATLA procedures. Any two groups had comparable age, ASA score, Charlson Comorbidity Index, and preoperative hemoglobin. The tumor size for RLA patients was 2.7 ± 1.1 cm, which was significantly smaller compared to patients who underwent TLA/RATLA (p = 0.000/0.000). Operative time was similar in any two groups, while estimated blood loss was lower for RATLA group (75.6 ± 95.6 ml) compared with the TLA group (131.1 ± 204.5 ml) (p = 0.041). Conversion to an open procedure occurred in only one (2.7%) patient in the TLA group for significant adhesion and hemorrhage. There were no significant differences between groups in terms of transfusion rate and complication rate. Length of stay was shorter for the RATLA group versus the TLA/RLA group (p = 0.000/0.029). In all groups, adrenocortical adenoma and pheochromocytoma were the most frequent histotypes. Conclusions Minimally invasive adrenalectomy is associated with expected excellent outcomes. In our study, the RATLA approach appears to provide the benefits of decreased estimated blood loss and length of stay. Robotic adrenalectomy appears to be a safe and effective alternative to conventional laparoscopic adrenalectomy.

Compared to non-obese patients, obese patients had greater median tumour size (2.9 vs. 2.5 cm, p&lt;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&lt;0.001), operative time (180 vs. 166 min, p&lt;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.</p><p><strong>Conclusion: </strong>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.<strong></strong></p>

Introduction Laparoscopic liver resection (LLR) in obese patients has been reported to be particularly challenging owing to technical difficulties and various comorbidities. Methods The safety and efficacy outcomes in 314 patients who underwent laparoscopic or open nonanatomical liver resection for colorectal liver metastases (CRLM) were analyzed retrospectively with respect to the patients’ body mass index (BMI) and visceral fat area (VFA). Results Two hundred and four patients underwent LLR, and 110 patients underwent open liver resection (OLR). The rate of conversion from LLR to OLR was 4.4%, with no significant difference between the BMI and VFA groups ( P = .647 and .136, respectively). In addition, there were no significant differences in terms of operative time and estimated blood loss in LLR ( P = .226 and .368; .772 and .489, respectively). The incidence of Clavien-Dindo grade IIIa or higher complications was not significantly different between the BMI and VFA groups of LLR ( P = .877 and .726, respectively). In obese patients, the operative time and estimated blood loss were significantly shorter and lower, respectively, in LLR than in OLR ( P = .003 and < .001; < .001 and < .001, respectively). There was a significant difference in the incidence of postoperative complications, organ/space surgical site infections, and postoperative bile leakage between the LLR and OLR groups ( P = .017, < .001, and < .001, respectively). Conclusion LLR for obese patients with CRLM can be performed safely using various surgical devices with no major difference in outcomes compared to those in nonobese patients. Moreover, LLR has better safety outcomes than OLR in obese patients.

Objective Minimally invasive adrenalectomy is a challenging procedure in obese patients. Few recent studies have advocated against robot-assisted adrenalectomy, particularly in obese patients. This study aims to compare operative outcomes between the robotic and laparoscopic adrenalectomy, particularly in obese patients. Materials and Methods A retrospective analysis was performed on all consecutive patients undergoing adrenalectomy for benign disease by a single surgeon using either a laparoscopic or robotic approach. Adrenal surgeries for adrenal cancer were excluded. Demographics, operative time, length of hospital stays, estimated blood loss (EBL), and intraoperative and postoperative complications were evaluated. Patients were divided into 2 groups; obese and nonobese. A sub-analysis was performed comparing robotic and laparoscopic approaches in obese and nonobese patients. Results Out of 120, 55 (45.83%) were obese (body mass index ≥ 30 kg/m2). 14 (25.45%) of the obese patients underwent a laparoscopic approach, and 41 (74.55%) underwent a robotic approach. Operative times were longer in the obese vs. nonobese groups (173.30 ± 72.90 minutes and 148.20 ± 61.68 minutes, P = .04) and were associated with less EBL (53.77 ± 82.48 vs. 101.30 ± 122, P = .01). The robotic approach required a longer operative time when compared to the laparoscopic approach (187 ± 72.42 minutes vs. 126.60 ± 54.55 minutes, P = .0102) in the obese but was associated with less blood loss (29.02 ± 51.05 mL vs. 138.30 ± 112.20 mL, P < .01) and shorter hospital stay (1.73 ± 1.23 days vs. 3.17 ± 1.27 days, P < .001). Conclusion Robot-assisted adrenal surgery is safe in obese patients and appears to be longer; however, it provides improvements in postoperative outcomes, including EBL and shorter hospital stay.

OBJECTIVE The effect of obesity on outcomes in minimally invasive surgery (MIS) approaches to posterior lumbar surgery is not well characterized. The authors aimed to determine if there was a difference in operative variables and complication rates in obese patients who underwent MIS versus open approaches in posterior spinal surgery, as well as between obese and nonobese patients undergoing MIS approaches. METHODS A retrospective review of all consecutive patients who underwent posterior lumbar surgery from 2013 to 2016 at a single institution was performed. The primary outcome measure was postoperative complications. Secondary outcome measures included estimated blood loss (EBL), operative time, the need for revision, and hospital length of stay (LOS); readmission and disposition were also reviewed. Obese patients who underwent MIS were compared with those who underwent an open approach. Additionally, obese patients who underwent an MIS approach were compared with nonobese patients. Bivariate and multivariate analyses were carried out between the groups. RESULTS In total, 423 obese patients (57.0% decompression and 43.0% fusion) underwent posterior lumbar MIS. When compared with 229 obese patients (56.8% decompression and 43.2% fusion) who underwent an open approach, patients in both the obese and nonobese groups who underwent MIS experienced significantly decreased EBL, LOS, operative time, and surgical site infections (SSIs). Of the nonobese patients, 538 (58.4% decompression and 41.6% fusion) underwent MIS procedures. When compared with nonobese patients, obese patients who underwent MIS procedures had significantly increased LOS, EBL, operative time, revision rates, complications, and readmissions in the decompression group. In the fusion group, only LOS and disposition were significantly different. CONCLUSIONS Obese patients have poorer outcomes after posterior lumbar MIS when compared with nonobese patients. The use of an MIS technique can be of benefit, as it decreased EBL, operative time, LOS, and SSIs for posterior decompression with or without instrumented fusion in obese 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.

OBJECTIVEObese patients have been shown to have longer operative times and more complications from surgery. However, for obese patients undergoing minimally invasive surgery, these differences may not be as significant. In the lateral position, it is thought that obesity is less of an issue because gravity pulls the visceral fat away from the spine; however, this observation is primarily anecdotal and based on expert opinion. The authors performed oblique lumbar interbody fusion (OLIF) and they report on the perioperative morbidity in obese and nonobese patients.METHODSThe authors conducted a retrospective review of patients who underwent OLIF performed by 3 spine surgeons and 1 vascular surgeon at the University of California, San Francisco, from 2013 to 2018. Data collected included demographic variables; approach-related factors such as operative time, blood loss, and expected temporary approach-related sequelae; and overall complications. Patients were categorized according to their body mass index (BMI). Obesity was defined as a BMI ≥ 30 kg/m2, and severe obesity was defined as a BMI ≥ 35 kg/m2.RESULTSThere were 238 patients (95 males and 143 females). There were no significant differences between the obese and nonobese groups in terms of sex, levels fused, or smoking status. For the entire cohort, there was no difference in operative time, blood loss, or complications when comparing obese and nonobese patients. However, a subset analysis of the 77 multilevel OLIFs that included L5–S1 demonstrated that the operative times for the nonobese group was 223.55 ± 57.93 minutes, whereas it was 273.75 ± 90.07 minutes for the obese group (p = 0.004). In this subset, the expected approach-related sequela rate was 13.2% for the nonobese group, whereas it was 33.3% for the obese group (p = 0.039). However, the two groups had similar blood loss (p = 0.476) and complication rates (p = 0.876).CONCLUSIONSObesity and morbid obesity generally do not increase the operative time, blood loss, approach-related sequelae, or complications following OLIF. However, obese patients who undergo multilevel OLIF that includes the L5–S1 level do have longer operative times or a higher rate of expected approach-related sequelae. Obesity should not be considered a contraindication to multilevel OLIF, but patients should be informed of potentially increased morbidity if the L5–S1 level is to be included.

Abstract Background The incidence of placenta preiva is rising. Cesarean delivery is identified as the only safe and appropriate mode of delivery for pregnancies with placenta previa. Anesthesia is important during the cesarean delivery. The aim of this study is to assess maternal and neonatal outcomes of patients with placenta previa managed with neuraxial anesthesia as compared to those who underwent general anesthesia during cesarean delivery. Methods A retrospective cohort study was performed of all patients with placenta preiva at our large academic institution from January 1, 2014 to June 30, 2019. Patients were managed neuraxial anesthesia and general anesthesia during cesarean delivery. Results We identified 1234 patients with placenta previa who underwent cesarean delivery at our institution. Neuraxial anesthesia was performed in 737 (59.7%), and general anesthesia was completed in 497 (40.3%) patients. The mean estimated blood loss at neuraxial anesthesia of 558.96 ± 42.77 ml were significantly lower than the estimated blood loss at general anesthesia of 1952.51 ± 180 ml (p < 0.001). One hundred and forty-six of 737 (19.8%) patients required blood transfusion at neuraxial anesthesia, whereas 381 out of 497 (76.7%) patients required blood transfusion at general anesthesia. The rate neonatal asphyxia and admission to NICU at neuraxial anesthesia was significantly lower than general anesthesia (2.7% vs. 19.5 and 18.2% vs. 44.1%, respectively). After adjusting confounding factors, blood loss was less, Apgar score at 1- and 5-min were higher, and the rate of blood transfusion, neonatal asphyxia, and admission to NICU were lower in the neuraxial group. Conclusions Our data demonstrated that neuraxial anesthesia is associated with better maternal and neonatal outcomes during cesarean delivery in women with placenta previa.

AbstractThe objective was to report the effect of obesity, utilizing a body mass index (BMI) threshold of 35 kg/m2, on outcomes and complications of multiple ligament knee injury (MLKI). It was hypothesized that obese patients would have longer intraoperative times and hospital length of stay, greater estimated blood loss, and higher rates of wound infection requiring irrigation and debridement (I&D) and revision ligament surgery. A retrospective review was performed on 143 individuals who underwent surgery for an MLKI between 2011 and 2018 at a single academic center. Patients were included if there was a plan for potential surgical repair/reconstruction of two or more ligaments. Patients with prior surgery to the affected knee or intra-articular fracture requiring reduction and fixation were excluded. Comparisons between obese and nonobese patients were made using two-sample t-test and either chi-square or Fisher's exact test for continuous and categorical variables, respectively. Significance was set at p < 0.05. Of 108 patients meeting inclusion criteria, 83 had BMI < 35 kg/m2 and 25 had BMI ≥ 35 kg/m2. Obese patients sustained higher rates of MLKI due to ultralow velocity mechanisms (28.0 vs. 1.2%; p = 0.0001) and higher rates of concomitant lateral meniscus injury (48.0 vs. 25.3%; p = 0.04). Among patients undergoing single-staged surgery, obese patients had significantly longer duration of surgery (219.8 vs. 178.6 minutes; p = 0.02) and more wound infections requiring I&D (20.0 vs. 4.8%; p = 0.03). In contrast, nonobese patients had higher rates of arthrofibrosis requiring manipulation under anesthesia and/or arthrolysis (25.3 vs. 0%; p = 0.003). Obese patients undergoing surgery of an MLKI have longer operative times, greater rates of wound infection requiring I&D, and lower rates of arthrofibrosis. Surgeons may consider these results when counseling patients on their postoperative course and risk for complications. Future research might focus on strategies to reduce complication rates in obese patients with MLKI. This is a Level III, retrospective comparative study.
