Anorectal Surgery is needed for patients  suffering from 

Anal Fissure

1. It is a small tear in the skin lining of the anal canal. The primary cause of anal fissure is hard stools due to constipation. It can also result from straining during bowel movements, chronic diarrhoea, anal sex, or any object inserted into the anus. You may experience the following symptoms:-
2. Bright red blood during a bowel movement
3. Severe sharp pain during and after a bowel movement
4. Visible cut or tear in the area
5. Most anal fissures can be cured without surgery with warm baths, medications, and sphincter relaxants, such as nitroglycerin ointments. Surgical therapies are performed only when other procedures do not heal the anal fissure. 

Anal Fistula

1. An anal fistula, also called fistula-in-ano, is an abnormal passage that forms between the anal canal and the skin near the anus. The primary cause of anal fistula is an anal gland that develops a pus-filled infection (abscess). It can also occur with conditions such as Crohn’s disease, radiation therapy for cancer, or an injury to the anal canal. You may experience the following symptoms of anal fistula:-
2. Fever and chills
3. Pain and swelling around the anus
4. Redness, soreness, or itching around the anal opening
5. Pus drainage near the anal opening

Haemorrhoids

1. Haemorrhoids occur when the blood vessels and veins around your anus and lower spectrum become swollen and irritated due to extra pressure on the veins. Haemorrhoids can either be deep inside the rectum (internal) where you cannot see or feel them, or they may lie under the skin around your anus (external). You may get haemorrhoids if you are pregnant, strain during bowel movements, or have a family history of haemorrhoids. You may experience the following symptoms:-
2. Bright red blood in your stool
3. Swelling or itching around the anus
4. Pain and irritation around the anus

Rectal Prolapse

1. Rectal prolapse occurs when a part of the rectum bulges out of the anal opening. It is primarily caused by the weakening of the muscles that support the rectum, resulting from constipation, giving birth, or defects in the pelvis. The symptoms of rectal prolapse include:-
2. Mucus in your stool
3. Feeling a bulge from the anus while sneezing or coughing
4. Abdominal pain or discomfort
5. Blood from the rectum
6. Anal pain, bleeding or itching
7. Trouble controlling bowel movements 

Anal Cancer

1. Cancer starts when abnormal cells mutate and grow out of control. These changed cells form a lump called a tumour. Anal cancers usually start in the cells that form the lining of the anus. It can spread to other layers of the anus and the sphincter muscles with time. The symptoms of anal cancer include:-
2. Pain or pressure around the anus
3. Leakage of fluid from the anus
4. Bleeding
5. A lump, swelling, or itching around the anus
6. Changes in bowel movements
7. Swollen lymph nodes in the anal area

Anal Condyloma

1. Anal condyloma or anal warts are growths on the skin around the rectal opening caused by the human papillomavirus (HPV). The symptoms of anal condyloma are rare but may include:-
2. Pain or discomfort
3. Itching
4. Bleeding
5. Discharge from the anus
6. Lump in the anal area

Pilonidal Disease

It is a chronic skin infection that affects the top of the gluteal cleft near the coccyx (tailbone). The condition is caused by loose hair penetrating the skin, leading to inflammations and infections. It is more common in men than women. Symptoms include:-

1. Pain
2. Redness
3. Drainage of abscess in the area

Perianal Abscess
