Purpose To describe a minimally invasive method to create multifocal full-thickness surgical iridectomy biopsies. Methods Seven patients suspected to have diffuse iris melanoma underwent multifocal surgical iridectomy biopsy through a single 1.0-mm clear corneal incision. A 25-G inked trocar was used to create one visible corneal portal, through which the anterior chamber was filled with sodium hyaluronate 1%. Then, a 25-G aspiration cutter probe was introduced through the corneal incision such that the aspiration portal was occluded by the iris biopsy sites. Then aspiration (600 mm Hg) cutting (300 cuts per minute) was used to create full- and partial-thickness surgical iridectomy biopsies at multiple locations. After each biopsy the probe was removed, and its contents aspirated into a separate 3-mL syringe (marked by clock hour location). The sodium hyaluronate 1% was removed and wound checked for leakage. Results Diagnostic specimens were obtained in all cases. Five were found to be diffuse iris melanomas and 2 were indeterminate iris melanocytic proliferations. No patients developed a secondary increase in intraocular pressure, hyphema, infection, cataract, or vision loss. No cases of intraocular tumor dissemination were observed. No patient complained of glare or monocular diplopia. Three of 7 corneal wounds were self-sealing. Conclusions Multifocal surgical iridectomy biopsy can be minimally invasive and effective allowing for partial- and full-thickness iris biopsy. Use of a 25-G aspiration cutting probe allowed for small incision surgery, rapid rehabilitation, and no significant complications.

Objective: Aim of the study is to Compare the astigmatism induced by a reduced temporal sclerocorneal tunnel incision manual small incision cataract surgery with an extended temporal clear corneal Phacoemulsification of similar width . Methods: A Prospective, randomised controlled study was carried out in 224 selected patients who were again divided into two groups - Group A (112 patients) and Group B (112 patients). Group A patients underwent temporal manual small incision cataract surgery with a 5.5 mm sclerocorneal incision and Group B underwent phacoemulsification by a 2.8 mm clear corneal temporal incision which was extended to 5.5 mm before IOL implantation. In both groups, a 5.25 mm rigid PMMA IOL was implanted in the bag. UCVA and BCVA of both group of patients was quantified and analyzed at 1 week and at 6 weeks Observation: It was seen that the mean surgically Induced astigmatism in group A (N=112) was 0.5625D , which was slightly lesser than that in Group B (N=112) which was 0.65D, although the p-value of 0.26 indicated that there was statistically no significant difference in visual outcomes between the two groups of patients. Here, a p-value of < 0.05 was considered statistically significant. Conclusion: In Skilled and Safe hands, refractive outcomes following performing a 5.5mm temporal sclerocorneal frown-incision manual small incision cataract surgery and a phacoemulsification procedure by a 2.8mm temporal clear corneal incision extended to 5.5mm for implanting a 5.25mm rigid PMMA IOL , are comparable.

The immediate and long-term results of treatment of 30 patients with severe pain syndrome of the lumbar region, who underwent operations on denervation of DOS, were studied. The aim of the study was to evaluate the effectiveness of minimally invasive technologies for the treatment of pain in the lumbar region (denervation of DOS), to study the near and distant results of these treatment methods. Denervation DOS is an effective minimally invasive method for the treatment of facet syndrome caused by spondylarthrosis. It allows in the early and distant postoperative periods to significantly reduce the pain syndrome and improve the quality of life of patients.

Abstract Background Spondylodiscitis is an unusual infectious disease, which usually originates as a pathogenic infection of intervertebral discs and then spreads to neighboring vertebral bodies. The objective of this study is to evaluate percutaneous debridement and drainage using intraoperative CT-Guide in multilevel spondylodiscitis. Methods From January 2002 to May 2017, 23 patients with multilevel spondylodiscitis were treated with minimally invasive debridement and drainage procedures in our department. The clinical manifestations, evolution, and minimally invasive debridement and drainage treatment of this refractory vertebral infection were investigated. Results Of the enrolled patients, the operation time ranged from 30 minutes to 124 minutes every level with an average of 48 minutes. Intraoperative hemorrhage was minimal. The postoperative follow-up period ranged from 12 months to 6.5 years with an average of 3.7 years. There was no reactivation of infection in the treated vertebral segment during follow-up, but two patients with fungal spinal infection continued to progress by affecting adjacent segments prior to final resolution. According to the classification system of Macnab, one patient had a good outcome at the final follow-up, and the rest were excellent. Conclusions Minimally invasive percutaneous debridement and irrigation using intraoperative CT-Guide is an effective minimally invasive method for the treatment of multilevel spondylodiscitis.

Image-guided percutaneous drainage is an excellent minimally invasive method for dealing with infectious complications in the pediatric population. A thorough understanding of drainage procedures in children can often lead to improved patient outcomes. Indications for percutaneous drainage will be reviewed, including abscesses related to appendicitis, post-surgical abscess formation, and abscesses related to Crohn's disease. This pictorial essay will help the radiologist better understand the common etiologies of abscesses in children that may require percutaneous drainage, the special considerations for catheter placement, patient preparation, and anesthesia or sedation issues unique to the pediatric population.

AbstractObjectives:This study assessed the utility of current sialendoscopes in the paranasal sinuses in a cadaveric model and evaluated novel uses for sialendoscopes.Methods:Currently available sialendoscopes were used for visualisation and performing interventions in the paranasal sinuses. Ten cadaver heads were studied before and after dissection. Outcomes included ostia identification, sinus cannulation, success of mucosal biopsy collection and image clarity.Results:Marchal and Erlangen sialendoscopes were found to be effective for both visualising and cannulating the sphenoid sinuses before and after dissection. Both types demonstrated poor maxillary ostia visualisation without dissection, but did allow treatment after antrostomy. Larger diameter sialendoscopes were associated with the lowest image distortion during maxillary ostia assessment. Mucosal biopsy collection within the sphenoid sinus, but not in the maxillary sinus, was possible before dissection.Conclusion:Sialendoscopes can be used for visualisation and performing interventions in the sinonasal cavity, but their utility is mainly limited to the sphenoid sinus. They may be considered a minimally invasive method for drug delivery and/or biopsy collection in the post-operative setting for all sinuses. Design improvements are suggested.
