A comparison of efficacy of erector spinae plane block versus serratus anterior plane block plus subcostal transversus abdominus plane block for bariatric laparoscopic sleeve gastrectomy surgery: study protocol for a randomised clinical trial.

BACKGROUND: Obesity is a rapidly growing global health concern. Limited long-term success of diet, behavioural modification and medical therapy have led to the increased performance of bariatric surgery. Laparoscopic sleeve gastrectomy, which permanently reduces the size of the stomach, has been shown to cause considerable weight loss, as well as improving or even eliminating obesity related medical comorbidities such as diabetes, obstructive sleep apnoea and hypertension. Unfortunately, this surgery can also result in significant postoperative pain which, when combined with the dangers of perioperative opioid administration for bariatric patients, can lead to a significantly reduced quality of recovery. Opioid-sparing analgesia has been widely recommended for perioperative bariatric patients, but research into the optimum regional analgesia approach for this surgery is lacking, with no trials to date comparing different regional analgesic techniques. This study protocol describes a randomised clinical trial aimed at answering this question, comparing the quality of recovery after laparoscopic sleeve gastrectomy for patients who receive erector spinae plane block, versus those who receive serratus anterior plane block plus subcostal TAP block. METHODS: We propose a prospective, randomised, blinded (investigator) clinical trial in a tertiary hospital in Ireland. Seventy patients presenting for laparoscopic sleeve gastrectomy will be randomised to two study groups-group A will receive bilateral erector spinae blockade; group B will receive left sided serratus anterior plane block plus subcostal TAP blocks. Both groups will receive the same dose of the same local anaesthetic and the different regional technique performed will be the only difference in their care. The primary outcome will be QoR-15 scores at 24 h postoperatively, a validated international tool for assessing a patient's overall postoperative recovery. DISCUSSION: Regional analgesia should be a mainstay of perioperative opioid-sparing analgesia where possible. This is especially important in the bariatric cohort who are particularly susceptible to the complications of perioperative opioid administration. To the best of our knowledge, this trial will be the first to compare efficacy of two different regional analgesia techniques for bariatric patients undergoing laparoscopic sleeve gastrectomy surgery. TRIAL REGISTRATION: This trial was pre-registered on clinicaltrials.gov, registration number NCT05839704, on March 5, 2023. All items from the World Health Organisation Trial Registration Data Set have been included.

Pain outcomes of outside-the-cage robotic thoracic surgery: a prospective matched-cohort study.

Management of acute and chronic pain after thoracic surgery for pulmonary resection or thymectomy remains a challenge for both thoracic surgeons and anesthesiologists. Advances in minimally invasive robotic procedures have made subcostal outside-the-cage (OTC) resections possible, but the procedure's pain benefits have not been previously measured. A single-center cohort was consented to undergo robotic-assisted thoracoscopic surgery (RATS) with an OTC or transthoracic (TT) approach. On every post-operative day (POD), patients were asked to complete the visual analog scale (VAS) of pain, assigning a score of 0-10 with higher scores equaling higher pain intensity. Additionally, patients' opioid consumption was recorded and classified using morphine equivalent dose (MED). Descriptive statistics of demographics, Mann-Whitney, and Chi-squared tests were performed in a matched analysis. Altogether, 50 OTC patients and 50 TT patients were included. For each group, 1 pneumonectomy, 19 lobectomies, 10 segmentectomies, and 20 thymectomies were performed. Between groups, most were male (n = 54; p = 0.42) and there were no differences in American Society of Anesthesiologists scores (p = 0.51), or tobacco consumption (p = 0.45). Patients who received an OTC approach experienced significantly lower pain scores on POD-0 (p = 0.001), POD-1 (p < 0.001), and POD-2 (p < 0.001). POD-3 OTC VAS scores were not different from those of the TT group (p = 0.09). Similarly, MED was lower for the OTC group on POD-0 (p < 0.001), POD-1 (p = 0.03), and POD-3 (p = 0.03). The RATS-OTC approach results in a more rapid decrease in self-reported pain by the patient as well as significantly lower levels of MED.

Diagnostic Pitfalls of the Bleeding Origin after a Percutaneous Renal Biopsy: A Report of Two Cases.

A percutaneous renal biopsy (PRB) is a standard procedure for diagnosing renal disease, but can cause bleeding complications. Bleeding after a PRB can be classified as early- or late-onset, depending on the timing of the onset of the bleeding symptoms (<24 h or ≥24 h). We herein report two patients who experienced bleeding complications: one experienced early-onset bleeding from the 12th subcostal artery, and the other experienced late-onset bleeding from an arteriovenous fistula between a branch of the renal artery and renal vein. In both cases, the origin of the bleeding vessel was misjudged during the first examination. We discuss the diagnostic pitfalls of the origin of bleeding after a PRB and propose measures to avoid falling such pitfalls.

Comparison of postoperative analgesia effects between subcostal anterior quadratus lumborum block and transversus abdominis plane block in bariatric surgery: a prospective randomized controlled study.

BACKGROUND: Currently, the prevalence of obesity is on the rise annually. Bariatric surgery stands out as the most efficacious approach for addressing obesity. Obese patients are more prone to experience moderate to severe pain after surgery due to lower pain thresholds. Regional block, as an important component of multimodal analgesia in bariatric surgery, is crucial in reducing opioid consumption and alleviating postoperative pain in patients undergoing bariatric surgery. Transversus abdominis plane block (TAPB) has gained widespread utilization in bariatric surgery; however, its limitation of inadequate reduction of visceral pain in obese patients remains a significant concern. Therefore, it is imperative to explore new and more efficient strategies for analgesia. Quadratus lumborum block (QLB) has emerged as a popular nerve block in recent years, frequently utilized in conjunction with general anesthesia for abdominal surgery. In the cadaver study of QLB, it was confirmed that the dye level could reach up to T6 when using the subcostal anterior quadratus lumborum muscle approach, which could effectively reduce the incision pain and visceral pain of bariatric surgery patients during the perioperative period. However, there is currently a lack of research on the use of subcostal anterior QLB in patients undergoing bariatric surgery. Our study aims to investigate whether subcostal anterior QLB can provide superior perioperative analgesic efficacy for bariatric surgery under general anesthesia compared to TAPB, leading to reduced postoperative opioid consumption and a lower incidence of postoperative nausea and vomiting (PONV). METHODS AND DESIGN: This study is a prospective, randomized controlled trial aiming to recruit 66 patients undergoing bariatric surgery. The participants will be randomly allocated into two groups in a 1:1 ratio: subcostal anterior QLB group (n = 33) and TAPB group (n = 33). The study aims to investigate the efficacy of subcostal anterior QLB and TAPB in obese patients who are scheduled to undergo bariatric surgery. Our primary outcome is to observe the amount of opioids used in the two groups 24 h after operation. The secondary outcomes included VAS of pain during rest/activity after operation, the type and dose of additional analgesics, the occurrence and severity of PONV, the type and dose of additional antiemetic drugs, postoperative anesthesia care unit (PACU) time, time of first postoperative exhaust, time to first out of bed activity, time to first liquid diet and postoperative admission days. DISCUSSION: Opioid analgesics are prone to causing adverse reactions such as nausea, vomiting, and respiratory depression, especially in obese patients. Multimodal analgesia, including nerve block, can effectively reduce the dose of opioids and alleviate their adverse effects. Currently, TAPB is the most prevalent nerve block analgesia method for abdominal surgery. Recent studies have indicated that subcostal anterior QLB offers advantages over TAPB, including a wider block plane, faster onset, and longer maintenance time. It is not clear which of the two nerve block analgesia techniques is better for postoperative analgesia in patients undergoing bariatric surgery. Our objective in this investigation is to elucidate the superior method between TAPB and subcostal anterior QLB for postoperative pain management in bariatric surgery.

Cryoneurolysis of the Subcostal Nerve: A Technical Description and Case Report.

Cryoneurolysis has been utilized for numerous persistent and intractable painful conditions, including phantom limb pain and postsurgical pain. Although there are reports on the effectiveness of cryoneurolysis in various regions, including the intercostal nerves, the subcostal nerve remains a common culprit of chronic pain for which the literature is scarce. Different modalities are commonly utilized to address subcostal neuropathic pain, such as non-opioid pharmacotherapy, including nonsteroidal anti-inflammatory drugs (NSAIDs) and anticonvulsants, site-specific regional anesthesia, and radiofrequency ablation.However, the analgesia provided by these modalities is often inadequate or short-lived. Cryoneurolysis of the subcostal nerve remains largely unexplored and may provide a promising solution.Here, we present the first technical description of ultrasound and fluoroscopic guided percutaneous cryoneurolysis of the subcostal nerve and the case of a patient with 14 years of lower thoracic rib pain who failed multiple interventions but achieved complete pain resolution at the three-month follow-up through this procedure.

Effect of postoperative intermittent boluses of subcostal quadratus lumborum block on pulmonary function recovery and analgesia after gastrectomy: a randomized controlled clinical trial.

BACKGROUND: Following the gastrectomy, the reduction in pulmonary function is partly attributed to postoperative pain. Subcostal quadratus lumborum block (QLB) has recently emerged as a promising component in multimodal analgesia. We aimed to assess the impact of intermittent boluses of subcostal QLB on pulmonary function recovery and analgesic efficacy after gastrectomy. METHODS: Sixty patients scheduled for gastrectomy were randomly assigned to either control group (multimodal analgesia) or intervention group (intermittent boluses of subcostal QLB plus multimodal analgesia). Two primary outcomes included the preservation of forced expiratory volume in the first second (FEV1) and the pain scores (0-10 cm visual analog score) on coughing 24 h postoperatively. We assessed the pulmonary function parameters, pain score, morphine consumption and number of rescue analgesia at a 24-h interval up to 72 h (Day1, Day2, Day3 respectively) as secondary outcomes. RESULTS: 59 patients were analyzed in a modified intention-to-treat set. The preservation of FEV1 (median difference: 4.0%, 97.5% CI: -5.7 to 14.9, P = 0.332) and pain scores on coughing (mean difference: 0.0 cm, 97.5% CI: -1.1 to 1.2, P = 0.924) did not differ significantly between two groups. In the intervention group, the recovery of forced vital capacity (FVC) was faster 72 h after surgery (interaction effect of group*(Day3-Day0): estimated effect (ß) =0.30 L, standard error (SE) =0.13, P = 0.025), pain scores at rest were lower in the first 3 days (interaction effect of group*(Day1-Day0): ß = - 0.8 cm, SE = 0.4, P = 0.035; interaction effect of group*(Day2-Day0): ß = - 1.0 cm, SE = 0.4, P = 0.014; and interaction effect of group*(Day3-Day0): ß = - 1.0 cm, SE = 0.4, P values = 0.009 respectively), intravenous morphine consumption was lower during 0-24 h (median difference: -3 mg, 95% CI -6 to -1, P = 0.014) and in total 72 h (median difference: -5 mg, 95% CI -10 to -1, P = 0.019), and the numbers of rescue analgesia was fewer during 24-48 h (median difference: 0, 95% CI 0 to 0, P = 0.043). Other outcomes didn't show statistical differences. CONCLUSION: Postoperative intermittent boluses of subcostal QLB did not confer advantages in terms of the preservation of FEV1 or pain scores on coughing 24 h after gastrectomy. However, notable effects were observed in analgesia at rest and FVC recovery.

A prospective case series to evaluate subcostal nerve injury with high-resolution ultrasound in posterior retroperitoneoscopic adrenalectomy.

BACKGROUND: Posterior retroperitoneoscopic adrenalectomy has several advantages over transabdominal laparoscopic adrenalectomy regarding operating time, blood loss, postoperative pain, and recovery. However, postoperatively several patients report chronic pain or hypoesthesia. We hypothesized that these symptoms may be the result of damage to the subcostal nerve, because it passes the surgical area. METHODS: A prospective single-center case series was performed in adult patients without preoperative pain or numbness of the abdominal wall who underwent unilateral posterior retroperitoneoscopic adrenalectomy. Patients received pre- and postoperative questionnaires and a high-resolution ultrasound scan of the subcostal nerve and abdominal wall muscles was performed before and directly after surgery. Clinical evaluation at 6 weeks was performed with repeat questionnaires, physical examination, and high-resolution ultrasound. Long-term recovery was evaluated with questionnaires, and photographs from the patients were examined for abdominal wall asymmetry. RESULTS: A total of 25 patients were included in the study. There were no surgical complications. Preoperative visualization of the subcostal nerve was possible in all patients. At 6 weeks, ultrasound showed nerve damage in 15 patients, with no significant association between nerve damage and postsurgical pain. However, there was a significant association between nerve damage and hypoesthesia (p = 0.01), sensory (p < 0.001), and motor (p < 0.001) dysfunction on physical examination. After a median follow-up of 18 months, 5 patients still experienced either numbness or muscle weakness, and one patient experienced chronic postsurgical pain. CONCLUSION: In this exporatory case series the incidence of postoperative damage to the subcostal nerve, both clinically and radiologically, was 60% after posterior retroperitoneoscopic adrenalectomy. There was no association with pain, and the spontaneous recovery rate was high.

Robotic thoracic surgery using the single-port robotic system: Initial experience with more than 100 cases.

OBJECTIVE: This study aimed to report the initial experiences of 115 patients who underwent robotic thoracic surgery using the da Vinci single-port robotic surgical system (Intuitive Surgical). METHODS: Robotic thoracic surgery using the da Vinci single-port robotic surgical system was performed on 115 patients between November 2020 and June 2023. Patient characteristics, intraoperative outcomes, and postoperative outcomes were analyzed retrospectively. RESULTS: The type of surgeries included thymectomy, mediastinal mass excision, anatomical pulmonary resection (including lobectomy and segmentectomy), esophagectomy, and enucleation of esophageal submucosal tumors in 41, 13, 54, 5, and 2 patients, respectively. The mean total operative time and chest tube duration for different procedures were as follows: thymectomy, 152.9. ± 6.7 minutes and 1.2 ± 0.5 days; mediastinal mass excision, 93.3 ± 26.5 minutes and 1.0 ± 0 days; anatomical pulmonary resection, 187.2 ± 55.8 minutes and 2.5 ± 1.5 days; esophagectomy, 485 ± 111.9 minutes and 12 ± 4.6 days; and enucleation of esophageal submucosal tumors, 170 ± 30 minutes and 5.5 ± 0.5 days, respectively. Conversion to a thoracotomy or sternotomy was not required. Conversion to video-assisted thoracic surgery occurred in 1 patient, and an additional port was applied in 2 patients. Two patients experienced postoperative complications greater than grade IIIa. CONCLUSIONS: Robotic thoracic surgery using the da Vinci single-port robotic surgical system is feasible and safe in various fields of thoracic surgery, including complex procedures such as anatomical pulmonary resection and esophagectomy. More complex thoracic surgeries can be performed with the continuous advancement and innovation of instruments in robotic systems.

Subcostal bilateral internal thoracic artery harvesting with the da Vinci Single Port system: an experimental feasibility study.

We evaluated the feasibility of harvesting bilateral internal thoracic arteries with the da Vinci Single Port system (SP) through a single left-sided subcostal incision. Complete bilateral mobilization with sufficiently long conduits for multivessel grafting was possible in 2 human cadavers and 2 live porcine. Creating the subcostal access and docking the SP system took between 14 and 21 min and the total harvest time ranged from 65 to 125 min in all models. No major bleeding was observed in the live porcine and hemostasis was managed with the available instrumentation. One porcine deceased during surgery due to ventricular fibrillation followed by cardiac arrest. The robotic harvesting was technically easily reproduced by the surgeons and required no additional rib-spreading. Further studies will be required to assess if this subcostal approach with the da Vinci SP system yields true clinical benefits in patients.

Visceral Artery Revascularization With the "Roof-Top" Approach: An Alternative Technique With Great Exposure of the Suprarenal Aorta.

Due to the extensive collateral arterial network, symptomatic chronic mesenteric ischemia is a relatively uncommon condition and is associated with severe atherosclerotic disease of all major visceral arteries. Open surgical repair has been commonly used to restore blood supply to the visceral arteries, and the "roof-top" approach has been advocated as an alternative technique to traditional midline incision, mainly because of the great exposure of the suprarenal aorta that it offers. Roof-top approach, in other words, bilateral subcostal incision, is a totally abdominal approach to the suprarenal aorta, and as the title says, it is like a roof-top on the abdominal wall. We present a case of a female patient with intestinal angina that was deemed unsuitable for endovascular repair (ER) and was treated with open surgical repair utilizing the "roof-top" approach.

Evolving Role of Three-Dimensional Echocardiography for Right Ventricular Volume Analysis in Pediatric Heart Disease: Literature Review and Clinical Applications.

Accurate knowledge of right ventricular (RV) volumes and ejection fraction is fundamental to providing optimal care for pediatric patients with congenital and acquired heart disease, as well as pulmonary hypertension. Traditionally, these volumes have been measured using cardiac magnetic resonance because of its accuracy, reproducibility, and freedom from geometric assumptions. More recently, an increasing number of studies have described the measurement of RV volumes using three-dimensional (3D) echocardiography. In addition, volumes by 3D echocardiography have also been used for outcome research studies in congenital heart surgery. Importantly, 3D echocardiographic acquisitions can be obtained over a small number of cardiac cycles, do not require general anesthesia, and are less costly than CMR. The ease and safety of the 3D echocardiographic acquisitions allow serial studies in the same patient. Moreover, the studies can be performed in various locations, including the intensive care unit, catheterization laboratory, and general clinic. Because of these advantages, 3D echocardiography is ideal for serial evaluation of the same patient. Despite these potential advantages, 3D echocardiography has not become a standard practice in children with congenital and acquired heart conditions. In this report, the authors review the literature on the feasibility, reproducibility, and accuracy of 3D echocardiography in pediatric patients. In addition, the authors investigate the advantages and limitations of 3D echocardiography in RV quantification and offer a pathway for its potential to become a standard practice in the assessment, planning, and follow-up of congenital and acquired heart disease.

Analgesic efficacy of an opioid-free postoperative pain management strategy versus a conventional opioid-based strategy following laparoscopic radical gastrectomy: an open-label, randomized, controlled, non-inferiority trial.

OBJECTIVE: In patients undergoing laparoscopic radical gastrectomy, the use of subcostal transversus abdominis plane block (STAPB) for completely opioid-free postoperative pain management lacks convincing clinical evidence. METHODS: This study included 112 patients who underwent laparoscopic radical gastrectomy at the 900TH Hospital of the Joint Logistics Support Force from October 2020 to March 2022. Patients were randomly divided into (1:1) continuous opioid-free STAPB (C-STAPB) group and conventional group. In the C-STAPB group, 0.2% ropivacaine (bilateral, 20 ml per side) was injected intermittently every 12 h through a catheter placed on the transverse abdominis plane for postoperative pain management. The conventional group was treated with a conventional intravenous opioid pump (2.5 µg/kg sufentanil and 10 mg tropisetron, diluted to 100 ml with 0.9% NS). The primary outcomes were the accumulative area under the curve of the numeric rating scale (NRS) score at 24 and 48 h postoperatively at rest and during movement. The secondary outcomes were postoperative recovery outcomes, postoperative daily food intake, and postoperative complications. RESULTS: After exclusion (n = 16), a total of 96 patients (C-STAPB group, n = 46; conventional group, n = 49) were included. We found there were no significant differences in the cumulative AUC of NRS score PACU-24 h and PACU-48 h between the C-STAPB group and conventional group at rest [(mean difference, 1.38; 95% CI, - 2.21 to 4.98, P = 0.447), (mean difference, 1.22; 95% CI, - 6.20 to 8.65, P = 0.744)] and at movement [(mean difference, 2.90; 95% CI, - 3.65 to 9.46; P = 0.382), (mean difference, 4.32; 95% CI, - 4.46 to 13.1; P = 0.331)]. The 95% CI upper bound of the difference between rest and movement in the C-STAPB group was less than the inferior margin value (9.5 and 14 points), indicating the non-inferiority of the analgesic effect of C-STPAB. The C-STAPB group had faster postoperative recovery profiles including earlier bowel movement, defecation, more volume of food intake postoperative, and lower postoperative nausea and vomiting compared to conventional groups (P < 0.001). CONCLUSIONS: After laparoscopic radical gastrectomy, the analgesic effect of C-STAPBP is not inferior to the traditional opioid-based pain management model. TRIAL REGISTRATION: ChiCTR2100051784.

Delphi consensus statement for understanding and managing the subcostal hernia: subcostal hernias collaborative report (scholar study).

INTRODUCTION: Subcostal hernias are categorized as L1 based on the European Hernia Society (EHS) classification and frequently involve M1, M2, and L2 sites. These are common after hepatopancreatic and biliary surgeries. The literature on subcostal hernias mostly comprises of retrospective reviews of small heterogenous cohorts, unsurprisingly leading to no consensus or guidelines. Given the limited literature and lack of consensus or guidelines for dealing with these hernias, we planned for a Delphi consensus to aid in decision making to repair subcostal hernias. METHODS: We adopted a modified Delphi technique to establish consensus regarding the definition, characteristics, and surgical aspects of managing subcostal hernias (SCH). It was a four-phase Delphi study reflecting the widely accepted model, consisting of: 1. Creating a query. 2. Building an expert panel. 3. Executing the Delphi rounds. 4. Analysing, presenting, and reporting the Delphi results. More than 70% of agreement was defined as a consensus statement. RESULTS: The 22 experts who agreed to participate in this Delphi process for Subcostal Hernias (SCH) comprised 7 UK surgeons, 6 mainland European surgeons, 4 Indians, 3 from the USA, and 2 from Southeast Asia. This Delphi study on subcostal hernias achieved consensus on the following areas-use of mesh in elective cases; the retromuscular position with strong discouragement for onlay mesh; use of macroporous medium-weight polypropylene mesh; use of the subcostal incision over midline incision if there is no previous midline incision; TAR over ACST; defect closure where MAS is used; transverse suturing over vertical suturing for closure of circular defects; and use of peritoneal flap when necessary. CONCLUSION: This Delphi consensus defines subcostal hernias and gives insight into the consensus for incision, dissection plane, mesh placement, mesh type, and mesh fixation for these hernias.

Completely portal robotic lobectomy in lung cancer: is subcostal specimen removal necessary?

BACKGROUND: The best place for specimen extraction is a relevant question since either after robotic or video-thoracoscopic lobectomy, both intercostal and subcostal routes can be potential extraction routes. In this study, we studied completely portal robotic lobectomies (CPRL-4) for pulmonary neoplasms to investigate the efficacy and feasibility of subcostal specimen removal by comparing the two techniques. MATERIAL AND METHODS: Between January 2014 and July 2021, data from 90 patients who underwent robotic thoracic surgery with a Da Vinci Surgical System SI (Intuitive Surgical Inc., Mountain View, California, USA) were collected and retrospectively analyzed. Out of 90 patients, we analyzed 36 CPRL-4 cases. We removed specimens traditionally via intercostal utility thoracotomy in the first 22 patients (group A) and via subcostal incision in the next consecutive 14 patients (group B). Operative parameters, postoperative parameters, the visual analog scale (VAS) and SF36 life quality scoring were comparatively analyzed. RESULTS: The mean docking time was significantly higher in group B than in group A (26.2 ± 5.3 vs 17.8 ± 4.1) (p = .001). In terms of early-stage postoperative pain, group B had significantly lower pain scores compared to group A (p < .05). There was no significant difference between the groups in terms of SF36 life quality scoring. CONCLUSION: We can conclude that performing a subcostal incision is not a sophisticated process, though it significantly prolongs the docking time. Although our study is based on a small group, we noticed that removing the specimen through the subcostal incision after CPRL-4 is potentially useful, has several advantages and it is a practical, feasible, and safe method.

Comparative study of the clinical efficacy of subcostal thoracoscopy and median sternotomy in treating thymoma: a propensity score-matching analysis.

OBJECTIVE: This study was performed to evaluate the clinical efficacy of subcostal thoracoscopy and median sternotomy as surgical approaches for thymoma resection and lymph node dissection. The feasibility, safety, and clinical outcomes of subcostal thoracoscopy were compared with those of median sternotomy. METHODS: The clinical data of 335 patients with thymoma were retrospectively analyzed. The patients were divided into the subcostal thoracoscopy group and the median sternotomy group. Propensity score matching was performed to obtain comparable subsets of 50 patients in each group. A comparative analysis was conducted on various parameters. RESULTS: All surgeries were successful, and no conversions to open thoracotomy were required in the subcostal thoracoscopy group. Significant differences in the operative time, intraoperative blood loss, chest tube drainage duration, postoperative hospital stay, patient satisfaction scores, pain assessment, and postoperative complications were observed between the two groups. However, there was no significant difference in the number of lymph nodes or lymph node stations dissected intraoperatively between the two groups. CONCLUSION: Subcostal thoracoscopy is not inferior to median sternotomy as a surgical approach for thymoma resection and lymph node dissection. Our research provides important new comparative data on minimally invasive thymoma resection.

Image-guided percutaneous cholecystostomy: challenging the norms.

Image-guided percutaneous cholecystostomy (IGPC) is a widely recognized and regularly employed procedure in numerous institutions, serving as an indispensable cornerstone in the management of patients with acute cholecystitis. The most up-to-date literature has found that the transperitoneal route is at least as safe as the transhepatic route and that both the trocar and Seldinger techniques are equally safe and effective. The above novel insights may offer reassurance and alleviate concerns among operators performing IGPC by dispelling the fixation on previously established beliefs and thus providing flexibility, which lightens the load on the operator. Future studies could further investigate these findings and shed light on potential disparities in the safety and efficacy profiles associated with the subcostal and intercostal approaches, different drainage catheter sizes, and/or the impact of operator experience on complication rates.

Outside the Cage Subcostal RATS Lobectomy: Technical Aspects and Results of the First Series of a Novel Approach to Pulmonary Lobectomy.

OBJECTIVE: The goal of minimally invasive surgery is to reduce trauma to patients and improve their postoperative outcomes. In this context, the utilization of robot-assisted thoracic surgery (RATS) in the treatment of lung cancer has increased worldwide. The feasibility of single-incision major pulmonary resections by RATS was recently reported, with the objective of minimizing the surgical trauma of the traditional multiportal RATS approach. However, both techniques require intercostal incisions, potentially causing immediate and chronic pain resulting from intercostal nerve injury. To reduce postoperative pain resulting from intercostal approaches, we developed a nonintercostal, outside the thoracic cage (OTC) approach for RATS lobectomy, avoiding intercostal instrumentation. This report aims to describe the results of the first reported series of OTC subcostal RATS lobectomies. METHODS: Retrospective analysis of a series of the first consecutive patients operated on using the novel OTC subcostal RATS lobectomy technique. RESULTS: Between August and December 2022, a total of 10 consecutive cases were analyzed. The median age was 63 (55 to 84) years, the mean body mass index was 29 (24 to 45) kg/m2, and the median American Society of Anesthesiologists score was III (II to IV). No serious adverse events were observed, and there was no conversion of the surgical technique. The mean operative time was 132.6 (98 to 223) min. The median length of stay was 2 days. No pain-related complications, readmissions, or 30-day mortality were observed. CONCLUSIONS: This series demonstrates that OTC RATS lobectomy is feasible and safe. A phase I clinical trial is currently underway to prospectively assess the safety of the technique as well as its clinical relevance.

Effects of Subcostal Anterior Quadratus Lumborum Block with and without Dexmedetomidine on Postoperative Rehabilitation in Patients Undergoing Laparoscopic Renal Surgery: A Prospective Double-Blinded Randomized Controlled Study.

Background: The combination of different anesthesia techniques or adjuvant drugs can relieve the stress response to surgery, reduce adverse reactions and improve the clinical outcome. We investigated the effects of subcostal anterior quadratus lumborum block (SQLB) with and without dexmedetomidine (DEX) on postoperative rehabilitation for laparoscopic renal surgery (LRS). Methods: We included 90 patients in this single-center study. All were scheduled for elective laparoscopic radical or partial nephrectomy under general anesthesia (GA). We randomly and evenly assigned them to three groups: Group GA (GA alone), Group QG (SQLB with 30 mL of 0.25% ropivacaine and GA), and Group DQG (SQLB with 30 mL of 0.25% ropivacaine plus 1 µg/kg DEX and GA). The primary outcomes were serum creatinine (Cr) and blood urea nitrogen (BUN) levels; the secondary outcomes included the average numeric rating scale (NRS) scores at rest and during activity within 48 h postoperatively; perioperative opioid consumption; the time to first ambulation, exhaust, and fluid intake, and postoperative adverse reactions. Results: The serum Cr and BUN levels in Group DQG decreased significantly compared with Group GA (P < 0.05). The average NRS scores in Group DQG were significantly lower than other two groups (P < 0.05). Furthermore, the indexes reduced significantly in Group QG compared with Group GA (P < 0.05). Groups DQG and QG had lower consumption of opioid compared with Group GA (P < 0.05). The recovery indicators in Groups DQG and QG were higher quality than Group GA (P < 0.05). The incidences of adverse reactions in Group DQG was significantly lower than the other groups (P < 0.05). Conclusion: SQLB with and without DEX could attenuate postoperative pain, reduce opioids requirement and side effects, as well as facilitate postoperative early rehabilitation. More interesting, SQLB with DEX could confer kidney protection. Clinical Trial Registration Number: The Chinese Clinical Trial Registry (ChiCTR2200061554).

Cardiac Point-of-Care Ultrasound (P.O.C.U.S.) Utilization for Hospitalists in the Assessment of Patients with Cardiac Complaints: An Educational Overview.

The use of cardiac point-of-care ultrasound (P.O.C.U.S.) is underutilized in the field of internal medicine for the assessment of patients with cardiac complaints. Numerous studies in emergency medicine, anesthesia, and critical care have demonstrated the successful application of cardiac P.O.C.U.S. in resident and attending physicians with limited prior exposure. This article review overviews the practical implementation of cardiac P.O.C.U.S. for hospitalists by discussing proper technique and assessment for common pathology seen in the medical ward setting. We describe how to assess for left ventricular (LV) systolic function, right ventricular (RV) systolic function, suspected acute coronary syndrome (ACS), post-myocardial infarction (MI) complications, suspected pulmonary embolus, and assessment of intravascular volume status. In each section, we overview the pertinent literature to show how cardiac P.O.C.U.S. has been used to directly impact patient care.

CT angiography of non-aortic thoracic arterial trauma.

While aortic injury is the most commonly cited thoracic arterial injury, non-aortic arterial injuries represent an uncommon but significant source of morbidity and mortality in blunt and penetrating thoracic trauma patients. Knowledge of the spectrum of vascular injury and anatomic considerations that dictate patterns of associated thoracic hemorrhage will assist the radiologist in the accurate and efficient diagnosis of these injuries. This article provides a review of anatomy, pertinent clinical exam and CT angiography findings, as well as therapeutic options for non-aortic thoracic arterial trauma.
