Start with what you need treated.

Intra-abdominal abscess treatment aims to drain the infected fluid collection and control the underlying source of infection, which can arise from complications of appendicitis, diverticulitis, bowel surgery, or other abdominal infections. In most cases, radiologists use CT or ultrasound guidance to place a small drainage catheter directly into the abscess, allowing infected fluid to drain out over several days while the patient receives intravenous antibiotics. More complex or multiple abscesses, or those not accessible by catheter, may require surgical drainage and, if needed, treatment of the underlying cause such as removing a diseased segment of bowel. Patients are monitored closely with blood tests and repeat imaging to confirm the infection is resolving. The drainage catheter is typically removed once drainage output decreases significantly and imaging shows resolution. Most patients recover well with appropriate combined drainage and antibiotic treatment, though the underlying cause may require further treatment once the acute infection has settled.

Subphrenic abscess treatment addresses a pus collection located in the space just beneath the diaphragm, which most commonly develops as a complication following abdominal surgery, perforation of an organ, or a severe abdominal infection. Treatment typically involves CT or ultrasound-guided percutaneous drainage, where a catheter is inserted through the skin directly into the abscess to allow the infected fluid to drain externally over several days. This is combined with a course of intravenous antibiotics tailored to the bacteria identified from the drained fluid. In cases where the abscess is not accessible by catheter or fails to resolve, surgical drainage may be necessary. Patients are closely monitored with repeat blood tests and imaging to confirm the infection is clearing. Most patients show significant improvement within a few days of adequate drainage and antibiotic therapy, with the catheter removed once drainage subsides and imaging confirms resolution.

Pelvic abscess treatment addresses a localized collection of pus within the pelvic cavity, commonly arising from conditions such as pelvic inflammatory disease, appendicitis, diverticulitis, or as a complication of gynecological or abdominal surgery. Depending on the size and location of the abscess, treatment involves either image-guided percutaneous drainage using a catheter inserted through the abdominal wall or vagina, or surgical drainage for larger or less accessible collections. This is always combined with a course of intravenous antibiotics targeting the likely causative bacteria, later adjusted based on culture results from the drained fluid. Patients are monitored closely for fever, pain, and blood test trends to confirm the infection is responding to treatment. The drainage catheter, when used, typically remains in place for several days until output decreases and follow-up imaging confirms resolution. Most patients recover fully with prompt, appropriate drainage and antibiotic treatment, though the underlying cause of the abscess may require separate ongoing management.

Anal sphincteroplasty repairs damage to the ring of muscle controlling bowel movements, most commonly caused by injury during vaginal childbirth, but also from trauma or prior surgery, resulting in difficulty controlling gas or stool (fecal incontinence). The surgeon identifies the torn ends of the sphincter muscle and overlaps or reapproximates them, reinforcing the repair with sutures to restore the muscle's ability to close the anal canal effectively. The procedure is performed under general or spinal anesthesia and typically takes one to two hours. A temporary low-residue diet and stool softeners are used after surgery to reduce strain on the healing repair. Recovery generally takes four to six weeks, with pelvic floor physical therapy often recommended to strengthen the repaired muscle further. Most patients experience significant improvement in bowel control, though results can vary depending on the extent of the original injury.

Appendectomy removes the appendix, a small pouch attached to the large intestine that can become inflamed and infected, a condition called appendicitis, which requires prompt surgical treatment to prevent rupture and more serious infection spreading throughout the abdomen. Most appendectomies today are performed laparoscopically, using several small incisions and a camera to remove the appendix with minimal scarring and faster recovery, though open surgery through a larger incision is used in complicated cases. The procedure is performed under general anesthesia and typically takes 30 to 60 minutes for straightforward cases. Patients are usually able to walk and eat within a day of surgery, with most discharged within one to two days if there are no complications. Mild pain at the incision sites is managed with pain medication during the first week. Most patients return to normal activity within one to two weeks, with prompt surgery generally leading to excellent outcomes.

Arthroscopic debridement of calcium deposits treats calcific tendinitis, a condition where calcium crystals build up within a tendon, most commonly in the shoulder's rotator cuff, causing significant pain and restricted range of motion. Using small incisions and a camera (arthroscope) to guide the procedure, the surgeon uses specialized instruments to break up and remove the calcium deposits directly from the affected tendon, often combined with smoothing of any surrounding inflamed tissue. The procedure is performed under regional nerve block or general anesthesia and typically takes 30 to 60 minutes. Patients often experience significant pain relief soon after surgery, though some post-operative soreness is expected for one to two weeks. Physical therapy is usually recommended following surgery to restore full joint mobility and strength. Most patients experience substantial and lasting relief from the pain associated with calcific deposits.

Augmentation cystoplasty increases bladder capacity for patients whose bladder is too small, stiff, or overactive to store urine effectively, a condition often related to neurogenic bladder, congenital abnormalities, or chronic inflammatory bladder conditions. The surgeon uses a segment of the patient's own intestine, most commonly from the small bowel, to create a patch that is sewn onto the bladder to enlarge its capacity and reduce internal pressure. This is a significant abdominal operation performed under general anesthesia, typically taking three to four hours. Patients require a catheter for bladder drainage during initial healing, and many need to perform intermittent self-catheterization long-term since the augmented bladder may not empty completely on its own. Regular follow-up, including urine tests and imaging, monitors bladder function and screens for potential long-term complications. Most patients experience significant improvement in bladder capacity, continence, and protection of kidney function.

Bartholin abscess drainage treats a painful, swollen collection of infected fluid that forms when one of the small Bartholin's glands near the vaginal opening becomes blocked and infected. The most effective treatment involves making a small incision to drain the abscess and placing a small catheter (Word catheter) or performing marsupialization, where the edges of the cyst are stitched open to create a permanent small opening that prevents the gland from re-blocking in the future. The procedure is quick, typically performed under local anesthesia in the office or general anesthesia in an operating room, taking 15 to 30 minutes. Pain and swelling improve rapidly within a day or two of drainage. A course of antibiotics is prescribed if there is significant surrounding infection. Recurrence is possible, particularly if simple drainage without marsupialization is used, but the procedure is generally very effective and well-tolerated.

Branchial cleft cyst surgery removes a congenital abnormality that forms in the neck during fetal development when certain embryonic structures fail to fully close, resulting in a cyst, sinus, or fistula that can become infected or enlarged over time if not treated. The surgeon carefully dissects and completely removes the cyst and any associated tract through a small incision in the neck, taking care to avoid nearby important structures such as nerves and blood vessels. The procedure is performed under general anesthesia and typically takes one to two hours, varying based on the tract's depth and complexity. Complete removal is important to prevent recurrence, as any remaining tissue can lead to the cyst reforming. Most patients recover well with minimal scarring and experience no further issues once the entire cyst and tract have been excised. Follow-up wound care ensures proper healing at the incision site.

Castleman disease treatment depends on whether the condition is localized (unicentric), affecting a single group of lymph nodes, or widespread (multicentric), involving multiple lymph node regions throughout the body. Unicentric disease is typically treated with surgical removal of the affected lymph node or mass, which is often curative and performed under general anesthesia depending on the location and accessibility of the affected nodes. Multicentric Castleman disease requires systemic treatment, often involving targeted therapy directed against interleukin-6, a signaling molecule driving the disease, along with immunosuppressive medication or chemotherapy in more severe cases. Treatment plans are individualized based on disease extent, associated symptoms, and any underlying viral infections that can be linked to certain forms of the disease. Regular monitoring with blood tests and imaging tracks response to treatment and watches for disease progression. Localized disease treated surgically generally has an excellent prognosis, while multicentric disease requires ongoing, long-term management.

Completion thyroidectomy removes any thyroid tissue remaining after a prior partial thyroid surgery, most commonly performed when a pathology report reveals unexpected thyroid cancer requiring total gland removal for proper staging and treatment, or when the remaining tissue causes ongoing symptoms such as compression or hyperthyroidism. The surgeon typically uses the same incision site as the original surgery to access and remove the remaining thyroid tissue, working carefully around scar tissue from the previous operation. The procedure is performed under general anesthesia and generally takes one to two hours. Patients are monitored after surgery for calcium levels and voice changes, since the parathyroid glands and nerves controlling the voice box run close to the thyroid. Lifelong thyroid hormone replacement medication is required after complete removal of the gland. Most patients recover well, with careful surgical technique minimizing the risks associated with re-operating in a previously operated area.

Diagnostic laparoscopy allows direct visual examination of the abdominal and pelvic organs when the cause of symptoms, such as chronic pelvic pain or unexplained abdominal findings, remains unclear despite blood tests and imaging studies like ultrasound or CT scan. The surgeon makes a few small incisions in the abdomen, through which a camera and instruments are inserted to inspect organs including the appendix, ovaries, fallopian tubes, and bowel, and can take tissue samples (biopsies) if needed. The procedure is performed under general anesthesia and typically takes 30 to 60 minutes, though it can be extended if a therapeutic procedure is performed at the same time based on findings. Patients typically experience minimal discomfort and can often go home the same day. Small incision sites heal quickly with minimal scarring. This procedure often provides a definitive diagnosis that guides further, more targeted treatment.
