Core Needle Biopsy (or core biopsy)
Is performed by inserting a small hollow needle through the skin and into the organ or abnormality to be investigated. The needle is then advanced within the cell layers to remove a sample or core. Needle biopsy is also a type of percutaneous (through the skin) biopsy. The needle may be designed with a cutting tip to help remove the sample of tissue. Core biopsy is often performed with the use of spring loaded gun to help remove the tissue sample.
Core biopsy is typically performed under image guidance such as CT imaging, ultrasound or mammography. The needle is either placed by hand or with the assistance of a sampling device. Multiple insertions are often made to obtain sufficient tissue, usually multiple samples are taken. Patients may experience a slight pressure, but usually do not experience significant pain. As tissue samples are taken, a click may be heard from the sampling instrument.
Mostly similar to FNA
The core tissue samples will be sent to the pathology laboratory for diagnosis.

The needle used during core needle biopsy, usually a 16, 14, or 11 gauge needle is used with the core needle biopsy procedure. The core needle biopsy needle also has a special cutting edge.
Three to six separate core needle insertions are typically needed to obtain a sufficient sample. Patients may experience a slight pressure during core needle biopsy but should not experience any significant pain. As tissue samples are taken, clicks may be heard from the needle and sampling instrument. Typically, samples approximately 0.75 inches long (approximately 2.0 centimeters) and 0.0625 inches (approximately 0.16 centimeters) in diameter are removed.

Vacuum Assisted Biopsy:
Core biopsy is sometimes suction assisted with a vacuum device. This method enables to removal of multiple samples with only one needle insertion. Vacuum assisted core biopsy is being used more and more in breast biopsy procedures and is guided via stereotactic mammography or ultrasound imaging. However, unlike core biopsy, the vacuum assisted biopsy probe is inserted just once into the tissue through a tiny skin nick. Multiple samples are then taken using a rotation of the sampling needle aperture (opening) and with the assistance of suction.

Endoscopic Biopsy
is a very common type of biopsy. Endoscopic biopsy is done through an endoscope (a fiber optic cable for viewing inside the body) which is inserted into the body along with sampling instruments. The endoscope allows the physician to visualize the abnormality and guide the sampling. Endoscopic biopsy may be performed of the gastrointestinal tract (alimentary tract endoscopy), urinary bladder (cystoscopy), abdominal cavity (laparoscopy), joint cavity (arthroscopy), mid-portion of the chest (mediastinoscopy), or trachea and bronchial system (laryngoscopy and bronchoscopy), either through a natural body orifice or a small surgical incision. The endoscopist can directly visualize an abnormal area on the lining of the organ in question and pinch off tiny bits of tissue with forceps attached to a long cable that runs inside the endoscope.

Punch Biopsy
is typically used by dermatologists to sample skin rashes, moles and other small masses. After a local anesthetic is injected, a biopsy punch, which is similar in function to a small (3 mm to 4 mm or 0.15 inch in diameter) version of a كلمة ممنوعةكلمة ممنوعةكلمة ممنوعةكلمة ممنوعةكلمة ممنوعةكلمة ممنوعة cutter, is used to cut out a cylindrical piece of skin. The opening is typically closed with a suture (small stitches) and heals with minimal scarring. Punch biopsy may also be performed when removing small tissue samples from the cervix.

Surface Biopsy
involves sampling or scraping the surface of a sore or tumor to remove cells for pathologic testing. Surface biopsy is often performed by dermatologists to remove a small piece of skin to test for carcinoma (cancerous tissue).

Surgical Biopsy (or Excisional Biopsy):
surgical biopsy can be excisional (removal of an entire lesion) or incisional (removal of a piece of a lesion). Until about a decade ago, most biopsies performed were open surgical procedures. However, surgical biopsy is less common now. Surgical biopsies can be performed on abnormalities that can be seen or felt by the surgeon or pre-operative imaging can help provide a road map to the lesion. In cases of non-palpable breast lesions, a percutaneous wire can be placed in or near the lesion using mammogram or ultrasound for guidance. This marker wire provides a target for the surgeon. The removed tissue is then histologically analyzed by a pathologist

السلام عليكم
الخزعة
هى تحليل طبي وهو اخذ خلايا او اغشية للفحص.
تفحص الخلايا تحت المجهر بواسطة طبيب متخصص بعلم الامراض و ايضا قد يتم تحليلها بواسطة التحليل الجزيئى بي سي ار
نوعان
1- خزعة جزئية (خلايا من العضو اي جزء يسير)
2- خزعة كلية و هي استئصال العضو كامل
وكلهما يتم نقلة للمختبر
اذا كانت العينة سائل او خلايا أخذت بواسطة ابرة تسمة needle aspiration biopsy.

عينة الخزعة دائما تؤخذ من اجزاء من العضو او الجهة المشكوك بها

ويتم تشخيص العينة حميد او خبيث و انواع و مستوى السرطان


اسف حبيت ان اوجز عن الخزعة بسبب كتابتي بالغة الانجليزية للاخ ينبوع المعرف
وشكرا

مشكور د/شوقي على الاجابه المفصله والشامله ... ريحتنا من البحث وجبت لينا شي جاهز مجهز :)

اقتباس: اما الدكتوراة كانت بحث و 30 ساعة ايضا و البحث في Pathogenesis in Bacterial Vaginosis

بما انك محضر بحث حول التهابات المهبل البكتيرية ... حبذا لو تكتب لنا شرح مفصل عن
- انواع الالتهابات المهبلية ..

- وكيف نفرق بين الالتهابات البكتيرية والطفيليه من ناحية الاعراض ..و الاشارات المرضية .. التشخيص .. العلاج ؟
