Safety of cholecystectomy performed by surgeons who prefer fundus first versus surgeons who prefer a standard laparoscopic approach

BackgroundAn alternative method to standard laparoscopic cholecystectomy (SLC) is the “fundus first” method (FFLC). Concerns have been raised that FFLC can lead to misinterpretation of important anatomical structures, thus causing complications of a more serious kind than SLC. Comparisons between the methods are complicated by the fact that FFLC is often used as a rescue procedure in complicated cases. To avoid confounding related to this we conducted a population-based study with comparisons on the surgeon level. MethodIn GallRiks, the Swedish registry for Gallbladder surgery, we stratified all cholecystectomies performed 2006–2020 in three groups: surgeries carried out by surgeons that uses FFLC in <20 % of the cases (N = 150,119), in 20–79 % of the cases (N = 10,212) and in 80 % or more of the cases (N = 3176). We compared the groups with logistic regression, adjusting for sex, age, surgical experience, year of surgery and history of acute cholecystitis. All surgical complications (bleeding, gallbladder perforation, visceral perforation, infection, and bile duct injury) were included as outcome. A separate analysis was done with regards to operation time. ResultsNo difference in incidence of all surgical complications or bile duct injury were seen between groups. The rates of bleeding (OR 0.34 [0.14–0.86]) and gallbladder perforation (OR 0.61 [0.45–0.82]) were significantly lower in the “fundus first > 80% group” and the operative time was shorter (OR 0.76 [0.69–0.83]). ConclusionIn this study including >160,000 cholecystectomies, both methods was found to be equally safe. Key messageDuring laparoscopic cholecystectomy, the standard method of dissection and fundus first dissection are equally safe surgical techniques. Surgeons need to learn both methods to be able to use the one most appropriate for each individual case.

Safety and Complications of Landmark-based Paravertebral Blocks: A Retrospective Analysis of 979 Patients and 4983 Injections.

This study aimed to determine the incidence of complications after landmark-based paravertebral blocks for breast surgery. The medical records of patients who received a paravertebral block for breast surgery between 2019 and 2022 were reviewed. Patient age, sex, type of procedure, number of injections, volume of injected anesthetic, and possible complications were noted. A record was identified as a possible serious block-related complication if there was concern or treatment for local anesthetic systemic toxicity, pneumothorax, altered mental status, or intrathecal/epidural spread. Other complications recorded were immediate postblock hypotension and nausea/vomiting requiring treatment and unanticipated postsurgical admission. Patients receiving ultrasound-guided paravertebral blocks were excluded from this study. Over a 3-year period, 979 patients received paravertebral blocks using the landmark technique for breast surgery, totaling 4983 injections. Overall, 6 patients required assessment for postblock issues (0.61%), including hypotension (2 patients), nausea (3 patients), and hypotension + altered mental status (1 patient). This latter patient was identified as having a serious complication related to the paravertebral block (0.1%). This patient had unintentional intrathecal spread and altered mental status that required mechanical ventilation. The incidence of block-related hypotension and nausea requiring treatment was thus 0.31% and 0.31% respectively. Four patients required unanticipated admission, but none were for block-related reasons. No patients in this study were found to have local anesthetic systemic toxicity or pneumothorax. Our study suggests that landmark-based paravertebral blocks for breast surgery result in a very low complication rate and are a safe technique for postsurgical analgesia.

Evaluation of Autoligation of The Spermatic Cord for Castration of Small Adult Dogs

Traditionally, when performing a canine castration, the spermatic cord is double ligated prior to removing the testicles. Double ligation with suture is thought to prevent hemorrhagic complications and has been considered necessary to prevent morbidity and mortality when performing these procedures. A relatively new technique has emerged where the spermatic cord is ligated on itself, or autoligated, in a manner similar to the way that feline spermatic cords are ligated when performing cat neuters. The purpose of the present study was to evaluate the rate of complications across a large number of dogs whose spermatic cords were autoligated rather than double ligated with suture. This prospective clinical study included 215 shelter-owned dogs that underwent autoligation of the spermatic cord during routine castration. Inclusion criteria included age of 5 months or older, and body weight of 11.4 kg or less. Age was obtained from records, when available, or estimated based on size, breed, and dentition. The primary outcome measure was defined as hemorrhage from the testicular pedicle, as the primary potential complication that would be expected from a novel or unproven ligation method. Thus, patients were monitored for intraoperative hemorrhage, postoperative bleeding, or development of a scrotal hematoma. Incisional bruising was also noted, but not attributed to bleeding from the testicular pedicle unless noted to be overtly greater than what is observed with traditional canine castration surgery. There were no intraoperative hemorrhage-related complications in any dog. Additionally, none of the patients experienced postoperative bleeding nor did any patient develop a scrotal hematoma. Minor complications were all mild and self-limiting. These included peri-incisional bruising in 10/215 (4.7%) and scrotal bruising in 8/215 (3.7%) for an overall complication rate of 18/215 (8.4%). No dog required hospitalization or medical care related to any surgical complication. The results of this study indicate that autoligation of the spermatic cord is a safe technique when utilized in the castration of adult dogs that weigh 11.4 kg or less. Anecdotally, many shelter veterinarians report using this technique and this publication serves to establish the safety of this practice, particularly for those practicing in high-quality/high-volume spay and neuter operations.

Pilot robotic mastectomy in Singapore (PRoMiSing I) study: first safety and feasibility prospective cohort trial in South East Asia.

Robotic mastectomy has been performed worldwide since 2015. The advantages of the robotic approach in nipple-sparing mastectomy have been proven with better visualization and preservation of blood supply to the nipple-areolar complex (NAC), with a lower incidence of necrosis. It also allows smaller incisions for both mastectomy and immediate breast reconstruction. To date, no centers in Singapore and Southeast Asia offer robotic mastectomy. We believe that robotic mastectomy is a feasible and safe technique that can be utilized by our population. This study aimed to ascertain the surgical outcomes and perform a learning curve analysis in patients undergoing robotic mastectomy in a multi-ethnic South East Asian population. A single arm prospective pilot study of eligible patients aged 21-70 years old with early breast cancer or high-risk patients indicated for risk reducing mastectomy who were eligible and consented for robotic mastectomy were enrolled in this trial from 22nd December 2022 to 15th December 2023. A total of 29 consecutive robotic mastectomies were performed. The mean total operative time was 95±10.2 minutes. The average blood loss was 5.7±1.9ml and the average length of stay was 1.05 days. The mean mastectomy specimen weight was 251 g, and there was no conversion to conventional mastectomy in any case. Furthermore, there were no 30-days morbidity or complications in terms of wound infection requiring intervention, flap and nipple-areolar complex (NAC) necrosis, and postoperative hematoma/bleeding requiring intervention. This study contributes to the current evidence that robotic mastectomy is a safe and feasible option, and could prove to be a great alternative to conventional mastectomy. Further prospective trials examining the long-term oncological outcomes of robotic mastectomy will be performed to establish the oncologic safety of this technique in breast cancer treatment.

The use of indocyanine green for lateral lymph node dissection in rectal cancer—preliminary data from an emerging procedure: a systematic review of the literature

IntroductionLateral lymph node dissection (LLND) for rectal cancer is still not a widely established technique owing to the existing controversy between Eastern and Western countries and the lack of well-designed studies. The risk of complications and the paucity of long-term oncological results are significant drawbacks for further applying this technique. The use of indocyanine green (ICG) near-infrared (NIR) fluorescence for LLND appears as a promising technique for enhancing postoperative and oncological outcomes. This review aims to evaluate the emerging role of ICG during LLND and present the benefits of its application.Materials and methodsSystematic electronic research was conducted in PubMed and Google Scholar using a combination of medical subject headings (MeSH). Studies presenting the use of ICG during LLND, especially in terms of harvested lymph nodes, were included and reviewed. Studies comparing LLND with ICG (LLND + ICG) or without ICG (LLND-alone) were further analyzed for the number of lymph nodes and postoperative outcomes.ResultsIn total, 13 studies were found eligible and analyzed for different parameters. LLND + ICG is associated with significantly increased number of harvested lateral lymph nodes (p < 0.05), minor blood loss, decreased operative time, and probably decreased urinary retention postoperatively compared with LLND-alone.ConclusionsThe use of ICG fluorescence during LLND is a safe and feasible technique for balancing postoperative outcomes and the number of harvested lymph nodes. Well-designed studies with long-term results are required to elucidate the oncological benefits and establish this promising technique.

Retroauricular endoscopic thyroidectomy: initial single-institution experiences.

Conventional thyroidectomy often results in visible scarring postoperatively. Endoscopic thyroidectomy offers the advantage of scarless surgery, especially beneficial for young adult women. The retroauricular approach uses a facelift incision well-known among surgeons and eliminates the need for gas insufflation due to the large working space. An early retrospective analysis was conducted on thirty-one individuals who underwent gasless retroauricular endoscopic thyroidectomy approach, focusing on isthmolobectomies (n = 26) and lobectomies (n = 5), with one case necessitating conversion to open thyroidectomy, from January 2016 to April 2017. Physical examination, laboratory, and histopathology findings were collected. The scar was evaluated using the Vancouver Scale System, while other surgical and oncological outcomes were documented and assessed. The average operative time was 154.2 ± 21.3min, with an average bleeding volume of 69.2 ± 52.1mL. The average length of stay was 4.7 ± 2.2days. All complications occurred were temporary and all subjects remained in good condition throughout the follow-up period. Most subjects (65.6%) were very satisfied with the scar concealed in the retroauricular area. Retroauricular endoscopic thyroidectomy is a safe and feasible remote access technique with excellent postoperative results.

Thoracodorsal to long thoracic nerve transfer in a patient with traumatic injury: A case report

Background: Traumatic injury to the long thoracic nerve causes paralysis of the serratus muscle, clinically expressed as winged scapula and functional impairment of the shoulder girdle. Treatment varies according to the severity of the injury, with a focus on early intervention for best results; however, the therapeutic approach remains a challenge at present. Case Description: We present the case of a 32-year-old male patient, athlete, right-handed, presented with bilateral paresis predominantly in the right arm, associated with paresthesia and changes in the coloring of the upper limbs. After being diagnosed with Thoracic Outlet Syndrome and undergoing surgery, vascular symptoms persisted with a significant loss of strength in the right shoulder. Winged scapula was observed and structural lesions were excluded on magnetic resonance imaging. Electromyographic studies confirmed the presumption of traumatic nerve involvement of the long thoracic nerve. Notwithstanding 6 months of physical therapy, there was no improvement, so a nerve transfer from the thoracodorsal nerve to the right long thoracic nerve was chosen. At 12 months, complete resolution of the winged scapula and functional recovery were observed. The patient also experienced a decrease in preoperative pain from 5/10 to 2/10 on the visual analog scale. Conclusion: Nerve transfer from the thoracodorsal nerve to the long thoracic nerve is a safe and effective technique to treat winged scapula due to long thoracic nerve injury.

Postsurgical Analgesic Effectiveness of Ultrasound-Guided Parasternal Block After Auricular Reconstruction Using Autologous Costal Cartilage in Pediatric Patients: A Randomized Controlled Trial.

To study the efficacy of ultrasound-guided parasternal block (US-PSI) in pediatric patients undergoing auricular reconstruction surgery. For this study, the authors recruited 60 children between the ages of 5 and 12 years who underwent auricular reconstruction with autologous costal cartilage (ACC) to correct microtia. They were randomized to receive either ultrasound-guided modified parasternal block or periprostatic local infiltration anesthesia (PLIA), with 30 cases in each group. Ultrasound-guided parasternal block was administered following anesthesia induction, whereas PLIA was administered after ACC harvest. Lastly, following surgery, all children were provided with patient-controlled intravenous analgesia with sufentanil, and the numeric pain rating scale (NRS) was used to assess the intensity of pain. Our primary outcomes were the resting NRS pain scores and the NRS scores upon coughing at 1, 6, 12, 24, and 48 hours postsurgery. Sufentanil consumption within the first 24 hours of surgery, the mean duration to first ambulation, and the usage of rescue analgesics were our secondary outcomes. The authors also recorded the occurrence of undesirable side effects as well as more serious side effects like pneumothorax. Pediatric patients who were administered US-PSI showed significantly reduced NRS chest pain scores at 6 and 12 hours postsurgery compared to those who received PLIA (P<0.05). In addition, sufentanil consumption within the first 24 hours postsurgery, duration to first ambulation, and use of rescue analgesics were significantly lower among patients in the US-PSI group when compared to those in the PLIA group (P<0.05). This study found that US-PSI was a highly efficacious and safe technique for postsurgical analgesia following auricular reconstruction with ACC in pediatric patients. Level II, therapeutic study.

"Brain-First" Total Body Retrograde Perfusion and Retrograde Cerebral Perfusion in Hemi-Arch Replacement

Objective: The purpose of this study is to compare the early outcomes of brain-first total body retrograde perfusion (Bf-TBRP) in comparison with reverse cerebral perfusion (RCP) under moderate hypothermia circulatory arrest (MHCA) for hemi-arch replacement surgery. Methods: We analyzed the data of 88 patients who underwent hemi-arch replacement with Bf-TBRP (n = 18) or RCP (n = 70) under MHCA at West China Hospital of Sichuan University between 1 January 2020, and 31 July 2022. In-hospital mortality, neurological deficits, and other adverse events were recorded, which were evaluated with logistic regression to determine risk factors. Results: There was no significant difference between the Bf-TBRP and RCP groups in in-hospital mortality, cardiac events, neurological deficits, dialysis, gastrointestinal complications, and paralysis (p &gt; 0.05). The Bf-TBRP group was associated with significantly shorter hospital stay [Bf-TBRP: 8 d (interquartile range (IQR), 7–10) vs. RCP: 10 d (IQR, 8–13), p = 0.03] and fewer platelet transfusions [Bf-TBRP: 1.0 (IQR, 0–1.0) vs. RCP: 1.0 (IQR, 1.0–2.0), p = 0.05] than the RCP group. On multivariable logistic regression analysis, emergency surgery (p = 0.05) and surgery duration (p = 0.03) were determined to be risk factors. Conclusions: The study showed that Bf-TBRP is a safe technique for patients undergoing hemi-arch replacement with MHCA.

Abdominocentesis and intra-abdominal pressure measurement in small animals.

To provide a video tutorial detailing how to perform "blind" and ultrasound-guided abdominocentesis for diagnostic and therapeutic guidance, and to provide a brief demonstration of intra-abdominal pressure measurement (IAP). Any cat or dog with suspicion of free abdominal effusion or patients requiring measurement of IAP. Abdominocentesis should be performed when there is high suspicion for peritoneal effusion based on physical exam and/or diagnostic imaging. The 4-quadrant tap uses 20-gauge or larger needles placed blindly in ≥ 1 of the 4 quadrants of the abdomen to collect abdominal fluid. In contrast, ultrasound allows visualization of fluid in the abdomen prior to percutaneous insertion of a needle and syringe to collect fluid. Regardless of collection technique, fluid should have immediate cytologic analysis and later can be submitted for biochemical parameters, additional cellular analysis by a pathologist, and culture and sensitivity (in rare cases if indicated). Intravesicular bladder pressure measurement using a manometer-urinary catheter system approximates the IAP when there is concern for organ hypoperfusion and compartment syndrome. Abdominocentesis can be performed with and without the use of ultrasound guidance. Intravesicular bladder pressure measurement is used to diagnose and trend IAP values before and after treatments are performed. Abdominocentesis is a simple and safe technique that all small animal clinicians should be comfortable performing. Effusion sampling can guide further diagnostics and treatments. Measurement of IAP is simple and requires no specialized equipment.

Impact of Different Operative Techniques for Patients With Adolescent Idiopathic Scoliosis on Frontal Curve Correction and Sagittal Balance.

Surgical correction of adolescent idiopathic scoliosis from the posterior approach can be performed by the "all screws" technique; hybrid technique with screws and hooks; hybrid technique or with screws, hooks, and tapes; or selective fusion (SF) or nonselective fusion (NSF). The aim of the present investigation was to analyze the influence from different operative techniques on frontal curve correction and sagittal profile in patients with adolescent idiopathic scoliosis. We conducted a retrospective analysis on 55 consecutive patients with scoliosis who had been treated by posterior instrumented fusion. We collected demographic data and analyzed pre- and postoperative radiographs. Statistical analysis was performed using SPSS version 25. Because data showed normal distribution, t tests were performed. Twenty-two patients were treated using the hybrid technique with screws and hooks; 25 were treated using the hybrid technique with screws, hooks, and tape; and 8 were treated using the all screws technique. An SF was performed in 32 patients and NSF in 23 patients. There was no significant difference with regard to curve correction of the main curve between the different techniques. Correction of the minor curve was significantly higher in NSF than in SF patients. In SF, there was a correction of the minor curve of 43.9%. Impact on sagittal balance showed no significant differences between NSF and SF. The different operative techniques did not show a difference with regard to the correction of the main curve. NSF showed a significantly higher degree of correction of the minor curve than SF. However, we still found a correction of 43.9% of the noninstrumented minor curve in SF. Thus, SF and hybrid techniques do not lead to inferior radiographic outcome. SF and hybrid techniques are safe and effective techniques that could be used as an alternative to NSF and all screw fixation in the operative treatment for scoliosis.

Safety and margin positivity rates of surgeon-performed intraoperative ultrasound-guided wire localization for breast cancer

BackgroundSurgeon-performed intraoperative ultrasound-guided wire localization (IOL) offers an improved patient experience and decreased cost compared to preoperative localization by radiology, yet literature on this technique is sparse. Here we evaluate the safety and margin positivity rate after surgeon-performed IOL for breast cancer. MethodsPatients with biopsy-proven breast malignancy and planned breast conservation who underwent IOL by a single breast surgeon between 2017–2023 and had follow-up at our institution were retrospectively identified. Patient and tumor characteristics, method of diagnosis, imaging findings, use of oncoplastic surgery, and follow-up data were analyzed. ResultsA total of 137 IOLs were performed for biopsy-proven ductal carcinoma in situ (DCIS) or invasive cancer. The median patient age was 69 years. Most patients had a non-palpable tumor (n = 104, 76.5%). 84.6% of patients underwent pre-operative biopsy by ultrasound guidance, 12.5% by stereotactic guidance, and 2.9% by MRI. In total, 7.3% of patients (n = 10) had positive margins, including 2 with invasive disease at the margin and 8 with DCIS at the margin. Nine patients underwent re-excision for positive or close margins, of which 8 had successful margin-negative breast conservation and 1 patient underwent mastectomy. Thirty-day postoperative complications occurred in 21 patients (15.3%). Of these, most (n = 19, 90.4%) had minor complications including seroma (n = 14), cellulitis (n = 3), and skin allergy (n = 2). At median follow-up of 20.4 months, no patients experienced recurrence. ConclusionsIn our single-surgeon series, IOL is a safe technique for localization of invasive carcinoma and DCIS with margin positivity, re-excision, and postoperative complication rates within previously published ranges. SynopsisThis study evaluates the safety of and re-excision rates after intraoperative surgeon-performed ultrasound-guided wire localization (IOL) for breast cancer. Results demonstrate margin positivity and re-excision rates equivalent to or lower than rates reported in literature utilizing preoperative localization techniques.

Feasibility and Analgesic Efficacy of Thoracolumbar Dorsal Ramus Nerve Block Using Multiorifice Pain Catheters for Scoliosis Surgery: A Prospective Cohort Study.

Approximately 38,000 scoliosis surgery correction operations are performed annually in the United States; these operations are associated with considerable postoperative pain which can be difficult to manage. This is largely attributed to an incision spanning multiple vertebral segments with paraspinal muscle dissection and retraction to facilitate the implantation of segmental hardware and rods. Frequently utilized analgesic modalities include intravenous patient-controlled analgesia and epidural analgesia, often in combination. We sought to ascertain the feasibility and analgesic efficacy of continuous thoracolumbar dorsal ramus nerve (TDRN) block using surgically placed multiorifice catheters. Forty-two patients diagnosed with idiopathic scoliosis who underwent a posterior spinal fusion (PSF) were enrolled after consent was obtained. Patients were managed utilizing a standardized Enhanced Recovery After Surgery) protocol including a perioperative opioid-sparing regimen. Data were collected at specified time intervals during the recovery period. These data points included pain scores using the Numeric Rating Scale. Parenteral or both oral and parenteral opioid consumption doses were also collected every 4 hours. Any significant postoperative adverse events were recorded as well. A total of 42 patients had surgically placed TDRN catheters, and 40 patients were included in this study. The patients all reported low to moderate pain scores with low opioid consumption postoperatively, while the TDRN catheter delivery of local anesthetic analgesics did not result in significant complications. A regional technique utilizing TDRN catheters could be a valuable component of the postoperative pain management protocols for PSF surgery, and additional studies are warranted. This study evaluated the feasibility and analgesic efficacy of TDRN catheters for postoperative pain control following multilevel PSF for idiopathic scoliosis. Continuous local anesthetic delivery through TDRN catheters is a feasible and safe technique for postoperative pain control in these patients. Selective blockade of the dorsal rami might have benefits over epidural analgesia or other regional techniques.

Mini Endoscopic Septoplasty for High Localized Nasal Septum Deviation: Surgical Technique, Outcomes, and Comparison With Regular Septoplasty.

This prospective cohort study aimed to describe the technique of mini endoscopic septoplasty for patients with a high localized nasal septum deviation in front of the middle turbinate and chronic sinusitis or nasal sinus fungus ball. Our primary objective was to investigate the indications and outcomes of this procedure, and the secondary objective was to compare it with regular endoscopic septoplasty. Patients with chronic sinusitis or nasal sinus fungus ball and high localized nasal septum deviation underwent mini endoscopic septoplasty, while those with a broad deviation of the nasal septum underwent regular endoscopic septoplasty. The study evaluated the procedure duration, blood loss, and complications associated with both methods. All patients were followed up for 3 months. Thirty patients underwent mini endoscopic septoplasty; another 30 underwent regular endoscopic septoplasty. Mini endoscopic septoplasty demonstrated a significantly shorter procedure duration and lower blood loss than regular endoscopic septoplasty. Neither group experienced operative complications, such as nasal septum perforation or hematoma. Mini endoscopic septoplasty is a safe, time-efficient, and effective technique indicated for highly localized nasal septum deviations in patients with chronic sinusitis or nasal sinus fungus ball. This procedure offers advantages in terms of the surgical approach and postoperative debridement. Future research could explore the broader clinical implications of these findings.

Outcomes of 15 dogs and two cats with metabone fractures treated with fluoroscopically guided normograde metabone pinning.

To report the outcomes of 15 dogs and two cats with metabone fractures treated with fluoroscopically guided normograde metabone pinning (FGNMP). Retrospective case series. A total of 15 client owned dogs and two cats with 57 metabone fractures. Description of FGNMP and reporting of the following data: signalment, pre- and postoperative radiographs, intramedullary pin diameter used, anesthesia, surgery and coaptation times, duration to normal weightbearing and bone union, postoperative care and complications. Median surgery time was 54 min (range: 26-99), median duration of coaptation was 14 days (range: 1-5 weeks), median time to normal weightbearing was 16 days (range: 2-45) and median time to bone union was 6 weeks (range: 4-12). All cases had at least 12 months of post-surgical follow-up with a median follow-up of 18 months (range: 12-70). No major complications occurred. Mild radiographic changes associated with subchondral bone sclerosis were noted on follow-up radiographs in 13/57 fractures. All cases returned to normal gait and full (15) or acceptable (2) function. In this study, FGNMP was an effective and safe technique for metabone fracture repair, requiring only short-term external coaptation in most patients. Time to bone union and return to normal function compared favorably to previously reported techniques. Fluoroscopically guided normograde metabone pinning provides an alternative technique for treatment of metabone fractures.

Optimized Management of Patulous Eustachian Tube: Shim Size Modifications to Minimize Middle Ear Effusion and Enhancing Treatment Outcomes.

Objective: In this retrospective case series, we reported 4 patients presenting with a patulous Eustachian tube (PET) to highlight our institutional management approach to PET with shim insertion and a modified shim with hydroxyapatite injection. Methods: A single institution retrospective review. Results: One case was complicated by otitis media effusion; thus, the shim was downsized under local anesthesia with an immediately improved effusion. Another patient managed with a bilateral shim of the same size but is still symptomatic on one side; therefore, we upsized it, and the symptoms disappeared. The last one developed biofilm formation and thick secretion even after downsizing. Hydroxyapatite injection was performed under local anesthesia using the same shim insertion protocol. Conclusion: Shim insertion for the treatment of PET is considered a safe, reversible, and adjustable technique, giving satisfactory results while avoiding middle ear effusion. It can be performed under local or topical anesthesia in the clinic, and size adjustment can be considered to get maximum relief without middle ear effusion. This case series highlights that adjusting the size of the shim is a suggested method to eliminate symptoms and avoid complications of shim without the need for myringotomy and ventilation tube.

Efficacy and Safety of Ultrasound Guided Inter-semispinal Plane Block for Postoperative Analgesia in Posterior Cervical Laminectomy - A Prospective Randomised Controlled Study.

Prospective, randomized controlled study. To assess the safety and efficacy of an ultrasound-guided ISP block for postoperative analgesia in posterior cervical laminectomy. 88 patients requiring posterior cervical laminectomy were randomized into two groups, those who underwent ISP block with multimodal analgesia (ISPB group) and those with only multimodal analgesia (control group). Demographic details, intraoperative parameters (blood loss, duration of surgery, perioperative total opioid consumption, muscle relaxants used), and postoperative parameters (numeric rating scale, satisfaction score, mobilization time, and complications) were recorded. The total opioid consumption (128.41 + 39.65vs 284.09 + 140.92mcg; P < .001), muscle relaxant usage (46.14 + 6.18mg vs 59.32 + 3.97mg; P < .001), surgical duration (128.61 + 26.08/160.23 + 30.99mins; P < .01), and intra-operative blood loss (233.18 + 66.08mL vs 409.77 + 115.41mL; P < .01) were significantly less in the ISPB group compared to the control. In the postoperative period, the control group's pain score was significantly higher (P < .001) in the initial 48 hours. The Modified Observer Alertness/Sedation Score (MOASS) score and satisfaction scores were significantly better in the ISPB compared to the control (P < .001). The mean time required to ambulate was statistically less in ISPB (4.30 + 1.64hours) when compared to controls (9.48 + 3.07hours) (P < .001). In patients undergoing posterior cervical laminectomy, ISP block is a safe and effective technique with better outcomes than standard multi-modal analgesia alone, in terms of reduced intra-operative opioid requirements and blood loss, better postoperative analgesia, and early mobilization.

CO2 Laser Frenuloplasty: Advancing Minimally Invasive Techniques for Rapid Healing and Improved Patient Outcomes

This study explores the innovative use of CO2 laser technology in frenuloplasty, a significant shift from classic methods like scalpel surgery or electrocautery towards a minimally invasive approach. The research involved 15 patients aged 25 to 50, undergoing frenuloplasty with a CO2 laser system equipped with a 7-inch defocused handpiece, set at 20 Hz and 0.3 W. This method diverges from conventional laser techniques, focusing on controlled laser passes combined with manual traction to elongate the fibrous tissue of the frenulum. The results demonstrated that the CO2 laser technique allowed for a precise and progressive modification of the frenulum, significantly reducing the risks of hemorrhage and secondary intention fibrosis. The healing process was notably expedited, with patients reporting satisfactory outcomes within a two-week period. Statistically significant improvements were observed in patient-reported outcomes, as evidenced by the increases in the Short Form Health Survey (SF-12) scores, with the mean Physical Component Summary (PCS) score rising from 32.5 to 47.5 and the mean Mental Component Summary (MCS) score from 39.3 to 52.3 (p &lt; 0.001 for both). The study concludes that CO2 laser frenuloplasty is an effective and safe technique, offering substantial benefits in terms of reduced healing time and enhanced patient satisfaction. The significant improvements in SF-12 scores underscore the positive impact on patient quality of life, advocating for the broader application of this technique in clinical practice. Further research is warranted to explore its potential in a wider clinical context.

THE ARTHROSCOPIC MANAGEMENT OF TALAR BODY FRACTURES

Talar body fractures are high energy intraarticular injuries that are best management by anatomical reduction and secure fixation to improve outcomes. The talus is relatively inaccessible surgically and requires extensive soft tissue dissection and/or osteotomies to gain adequate open visualisation. There are a small number of case reports on arthroscopic assisted fixation in the literature. This case series reports on the technique and early outcomes of six patients all of whom presented with significant intraarticular displacement and who were managed entirely arthroscopically.The fractures were of the main body of the talus involving the ankle and subtalar joints and all had preoperative CT scans. All six patients underwent posterior ankle and subtalar arthroscopy with cannulated screws used to stabilise the fractures after reduction. Visualisation of the fracture reduction was excellent. After 10 days in a backslab, the patients were protected in a boot and encouraged to actively move their ankles. Weight bearing was permitted once union appeared complete.There were no early complications of infection, avascular necrosis or VTE. There was one patient that had a non-clinically significant migration of a screw. Two patients were lost to follow up early due to being visitors. The mean length of follow up was 12 months in the remainder. The remaining four patients all returned to their preoperative level of activity. All had demonstrable subtalar stiffness. There was no early post-traumatic arthritis.This series represents the largest so far published. The main flaw in this report is the lack of long term follow up. While this report cannot state superiority over open techniques it is a safe, effective and acceptable technique that has significant conceptual benefits.
