While an anal abscess is an infection within one or more of the anal spaces, an anal fistula (Choice B) is a tunneling between the anus or rectum and another epithelial lined space (eg, the skin overlying the drainage site). Fifty percent of patients with anal abscesses will go on to develop a chronic fistula from the involved anal gland to the overlying skin. Patients with fistulas typically present with an anal abscess that persists after incision and drainage, or with a pustule-like lesion in the perianal or ischiorectal area that continually drains. Surgical repair is usually necessary to eliminate the fistula while preserving fecal continence.

Tummy tuck surgery, also known as abdominoplasty, removes excess fat and skin and, in most cases, restores weakened or separated muscles creating an abdominal profile that is smoother and firmer. A flat and well-toned abdomen is something many of us strive for through exercise and weight control. Sometimes these methods cannot achieve our goals. Even individuals of otherwise normal body weight and proportion can develop an abdomen that protrudes or is loose and sagging. The most common causes of this include: Aging Heredity Pregnancy Prior surgery Significant fluctuations in weight What tummy tuck surgery can't do A tummy tuck is not a substitute for weight loss or an appropriate exercise program. Although the results of a tummy tuck are technically permanent, the positive outcome can be greatly diminished by significant fluctuations in your weight. For this reason, individuals who are planning substantial weight loss or women who may be considering future pregnancies would be advised to postpone a tummy tuck. A tummy tuck cannot correct stretch marks, although these may be removed or somewhat improved if they are located on the areas of excess skin that will be excised.

Video demonstrating Breast Conservation Surgery with Type 1 Oncoplasty for an Early Breast Cancer.

ECG interpretation gets a memorable twist in this teaching video, which uses dance movements to represent the waveforms of the electrocardiogram. It is a light-hearted study aid for remembering how electrical activity in the heart appears on a tracing. For students of cardiology. Educational only — not medical advice.

A walk through of an interactive about male to female sex reassignment surgery.

The abortion pill is a medicine called mifepristone that ends an early pregnancy.In general, it's used up to 70 days — 10 weeks — after the first day of a woman's last period. Patients over this mark can have an in-clinic abortion procedure.

3D scans show still pictures of your baby in three dimensions. 4D scans show moving 3D images of your baby, with time being the fourth dimension. It's natural to be really excited by the prospect of your first scan. But some mums find the standard 2D scans disappointing when all they see is a grey, blurry outline.

The IUD is birth control that’s very effective and convenient. How does an IUD work to prevent pregnancy?

From a dermatology centre, this long demonstration shows foam sclerotherapy for leg veins. The clinician narrates while injecting successive veins, comparing foam and liquid sclerosant, watching the needle tip, and explaining which vessel sizes suit each. It is a detailed procedural record for education in vein treatment.

Operating-room footage shows a dynamic reconstruction of the Achilles tendon with a composite anterolateral thigh flap. The silent recording follows the surgical team's work during the reconstruction. It is presented for education in plastic and reconstructive surgery. The recording runs just under three minutes in total.

A teaching case shows an endotracheal tube placed in the esophagus during surgery and recognized at once. The narration explains why the tube is left in place temporarily until the airway is secured. It is used for education in anesthesia and airway management. The case is presented as it unfolded in the operating room.

Support and encouragement during a natural water birth are the focus of this recording, which follows a laboring mother in a birthing pool with her birth team around her. It shows the supportive role of midwives and partners during delivery. Shared for childbirth education. For learning purposes only — not medical advice.

Working slice by slice, this lecture reviews a CT scan of the abdomen. The narrator names organs and vessels at each level and highlights an incidental large clot in the superior mesenteric vein, before coronal reconstructions close the study. It is an anatomy-focused teaching resource in Radiology.

Cervical cerclage can be placed via transvaginal, open transabdominal, or laparoscopic transabdominal approach, preferably before pregnancy. Recurrent late miscarriages may be due to a weak (sometimes called an incompetent) cervix that shortens or opens too early in pregnancy. Cervical cerclage involves placing a stitch around the upper part of the cervix to keep it closed; the operation may be carried out through the vagina, or through the abdomen, as an open or laparoscopic ('keyhole') procedure.

An egg cannot be fertilized when there are no sperm in the semen. The testicles continue to produce sperm, but the sperm are reabsorbed by the body. (This also happens to sperm that are not ejaculated after a while, regardless of whether you have had a vasectomy.) Sperm are made in the testicles. They pass through two tubes called the vasa deferentia to other glands and mix with seminal fluids to form semen. Vasectomy blocks each vas deferens and keeps sperm out of the seminal fluid. The sperm are absorbed by the body instead of being ejaculated.

Do penises have bones? This educational video explains the anatomy behind the question — humans do not have a penile bone (baculum), unlike many other mammals, and erection is a blood-flow process instead. Educational only — not medical advice.

This procedure video documents the removal of jigger fleas embedded in the skin, a condition called tungiasis, followed by cleaning and care of the affected areas. The footage is shared for clinical teaching about a common parasitic skin problem in endemic regions. Educational only — not medical advice.

Anatomy of Anterior Abdominal Wall

This narrated anatomy laboratory demonstration shows removal of the calvarium and brain in a cadaveric dissection. The instructor explains the saw cuts, separation of the dura, and identification of cranial nerves and dural venous sinuses as the dissection proceeds. It is a detailed study recording for neuroanatomy teaching.
