The Efficacy of Erector Spinae Plane Block Versus Subcostal Transversus Abdominis Plane Block in Laparoscopic Nephrectomy: A Randomized Clinical Trial.

OBJECTIVES: This study compared the efficacy and safety of erector spinae plane block (ESPB) versus subcostal transversus abdominis plane (TAP) block in reducing postoperative pain among patients undergoing laparoscopic nephrectomy. METHODS: This randomized clinical trial enrolled 70 adult patients, ASA physical status I or II, who underwent total (radical) laparoscopic nephrectomy under general anesthesia. Patients were randomly assigned to 2 groups. Group ESPB received an ultrasound-guided ESPB at the T7 transverse process level, while group TAP received an ultrasound-guided subcostal TAP block. The primary outcome was the total amount of morphine consumed at 6 and 24 hours postoperatively. Secondary outcomes included the incidence of patients requiring opioid analgesia, time to rescue analgesia, visual analog scale of pain intensity, time to postoperative ambulation, intraoperative and postoperative hemodynamics, arterial partial pressure of oxygen to fraction of inspired oxygen (PaO 2 /FiO 2 or P /F) ratio, and incidence of complications. RESULTS: Compared with the TAP group, the ESPB group exhibited significantly lower median morphine consumption at 24 hours ( P =0.032), prolonged time to first analgesic rescue ( P =0.049), and lower incidence of rescue morphine requirement (OR=0.23; 95% CI=0.06-0.94; P =0.031), with lower visual analog scale pain scores at 12, 18, and 24 hours postoperatively ( P <0.001). The mean arterial blood pressure and heart rates were comparable between groups. No significant adverse effects from either approach. DISCUSSION: In laparoscopic nephrectomy, ultrasound-guided ESPB may safely and effectively be used to improve pain management and reduce pain intensity, with stable hemodynamics and a comparable risk of postoperative complications to the ultrasound-guided subcostal TAP block.

ARMC5 mutations in primary bilateral macronodular adrenal hyperplasia: a family case report.

BACKGROUND: Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a rare cause of overt Cushing's syndrome (CS), which usually manifests as bilateral macronodular adrenal nodules and varying levels of cortisol secretion. Previous studies have shown that ARMC5 play a huge role in the occurrence of PBMAH, which may be inherited to family members and lead to more severe clinical symptoms. ARMC5 variants may be associated with meningiomas, which is also illustrated by our report. CASE PRESENTATION: This is a 41-year-old male patient with high blood pressure for 10 years and multiple adrenal nodules on both sides. In addition, the patient also suffered from pituitary microadenoma and meningioma. According to the patient's clinical manifestations, laboratory tests, imaging examinations, and the results of whole exon gene testing, we diagnosed the patient with PBMAH. The patient underwent a posterior laparoscopic nephrectomy of the left adrenal gland. Pathology reported a left macronodular adrenal hyperplasia, multifocal, 2 cm to 3 cm in diameter. Molecular analysis of DNA extracted from the patient's peripheral blood revealed an ARMC5 heterozygous mutation, which was classified as likely pathogenic. CONCLUSION: Screening of family members of PBMAH patients with ARMC5 germline mutations and active monitoring of family members carrying ARMC5 variants are recommended.

Perioperative safety and survival outcomes of robot-assisted partial nephrectomy in elderly patients with localized renal cell carcinoma: an overlap-weighted Asian cohort study.

The value of robot-assisted partial nephrectomy (RAPN) in elderly Asian patients with localized renal cell carcinoma (RCC) remains insufficiently defined. We retrospectively analyzed 339 patients (≥ 70 years) with localized RCC treated at a single Asian center between 2015 and 2025, including 119 undergoing partial nephrectomy (PN) and 220 undergoing radical nephrectomy (RN). Propensity score overlap weighting (OW) was applied to compare PN versus RN and, within the PN cohort, RAPN versus laparoscopic partial nephrectomy (LPN). Three open partial nephrectomy cases were summarized descriptively and retained only in exploratory sensitivity analyses. Weighted logistic regression and Cox models with robust standard errors evaluated Clavien-Dindo grade ≥ II complications and overall survival (OS). After OW, PN was associated with better early postoperative renal functional preservation than RN but a greater incidence of grade ≥ II complications (36.4% vs. 17.6%; weighted p < 0.001); OS was similar. Within the PN cohort, RAPN had longer operative time than LPN (weighted p = 0.030), whereas warm ischemia time, early postoperative eGFR, and grade ≥ II complications (31.8% vs. 40.4%; weighted p = 0.414) were not significantly different. Exploratory analyses favored RAPN, but only one death occurred in this group, and residual confounding remains possible. PN may preserve early renal function in selected older patients, while RAPN appears feasible in experienced centers; its survival association remains hypothesis-generating.

Post-operative pain, nausea, vomiting and optic nerve sheath diameter following total intravenous versus inhalational anesthesia for adults undergoing robotic transabdominal surgery - a systematic review and meta- analysis.

BACKGROUND: The introduction of robotic-assisted abdominal surgery is aimed at reducing the primary and secondary adverse outcomes. Anesthesia in robotic surgery varies from anesthesia for open or laparoscopic surgical procedures. The choice of anesthesia influences the perioperative control of pain, nausea, vomiting, and Optic nerve sheath diameter (ONSD). The purpose of this systematic review was to assess outcome variation in patients undergoing transabdominal robot-assisted surgery done under total intravenous anesthesia or inhalational anesthesia. METHODOLOGY: We searched the Cochrane Central Register of Controlled Trials, PubMed, and Google Scholar (January, 2017 to June, 2024). Search terms included "Anesthesia", "Robotics", "prostatectomy", hysterectomy", "nephrectomy", "cholecystectomy" and "cystectomy" with the Boolean operators "AND" and "OR". We searched for randomized controlled trials (RCTs) including adults of both genders aged 18 years and above, who underwent transabdominal robotic-assisted laparoscopic surgery and targeting the consequences related to TIVA or inhalational anesthesia. We reviewed titles and abstracts and proceeded to full-text articles of the eligible studies relevant to inclusion criteria. Mean and standard deviations with 95% CI were calculated. Forest plots were used to present data visually. RESULTS: Six studies (340 patients) were included. We found only one study in which post-operative pain was assessed and results favored intravenous anesthesia in robotic transabdominal surgery. Only two studies reported post-operative nausea and vomiting (PONV). Both studies stated that PONV is reported in few patients in the inhalation anesthesia group. We found evidence suggesting that change in ONSD measurements at 10 min after induction (MD 0.04,95% CI -0.02 to 0.11 p = 0.19) and 40-60 min after Trendelenburg position (MD -0.26, 95% CI -0.34 to 0.17, p = 0.16) are much less in intravenous anesthesia group than in inhalation anesthesia group. Total intravenous anesthesia maintains the ONSD and hence the ICP better than inhalational anesthesia in robotic transabdominal surgery with CO2 pneumoperitoneum in Trendelenburg positioning requirements. It would be a safer choice than inhalational anesthesia due to fewer adverse events. CONCLUSION: This review concludes that TIVA is a better choice than inhalational anesthesia for transabdominal robotic-assisted surgery in urology, gynecology, and gastroenterology in both male and female patients.
