Caesarean Section (C-section)

Mr Usman Jaffer explains some of the factors that may be important to consider when deciding which operation to have for abdominal aortic aneurysm (AAA). Research from our institution shows that there are a number of factors identified by key stakeholders (patients, surgeons, radiologists, anaesthetists, intensive care doctors, peri-operative doctors) that can allow you to make a more informed decision with your doctors. These include: pre-existing medical conditions, post-operative complications, 30-day mortality, type of anaesthesia, long-term durability of operation, time to return to normal activities, post-operative pain, patient expectations, impact on carers, personalised information, professional advice, involving others (family/friends), uncertainty, how invasive the surgery is, patient journey, patient values, social factors, need for follow up, length of hospital stay, probability of intensive care admission, impact of energy levels.

Treatment of anal fistula: A fistula without symptoms found on regular check up usually requires no therapy . [3,4] In case of anorectal abscess surgery for fistula repair should not be performed (unless the fistula is superficial and the tract is obvious). In the acute phase, simple incision and drainage of the abscess are sufficient. [5] Only 7-40% of patients will develop a fistula. Recurrent anal sepsis and fistula formation are twofold higher after an abscess in patients younger than 40 years and are almost threefold higher in non diabetics. Preoperative considerations include the following: • Rectal irrigation with enemas should be performed on the morning of the operation • Anesthesia can be general, local with intravenous sedation, or a regional block • Administer preoperative antibiotics Intraoperative considerations include the following: • Examine the patient under anesthesia to confirm the extent of the fistula • Identifying the internal opening (inside the anus) to prevent recurrence is imperative • A local anesthetic block at the end of the procedure provides postoperative analgesia Fistulotomy: The laying-open technique (fistulotomy) is useful for 85-95% of primary fistulas (ie, submucosal, intersphincteric, and low transsphincteric). [6, 7, 8, 9] The most common type of surgery for anal fistulas is a fistulotomy. This involves cutting along the whole length of the fistula to open it up so it heals as a flat scar.A fistulotomy is the most effective treatment for many anal fistulas, although it's usually only suitable for fistulas that don't pass through much of the sphincter muscles, as the risk of incontinence is lowest in these cases. If your surgeon has to cut a small portion of anal sphincter muscle during the procedure, they will make every attempt to reduce the risk of incontinence.In cases where the risk of incontinence is considered too high, one of the procedures below may be recommended instead. Seton techniques: If your fistula passes through a significant portion of anal sphincter muscle, your surgeon may initially recommend inserting a seton. A seton is a piece of surgical thread that is left in the fistula for several weeks to keep it open. This allows it to drain and helps it heal, while avoiding the need to cut the sphincter muscles. Loose setons allow fistulas to drain, but don't cure them. To cure a fistula, tighter setons may be used to cut through the fistula slowly. This may require several procedures that your surgeon can discuss with you. Seton Placement: A seton can be placed alone, combined with fistulotomy, or in a staged fashion. This technique is useful in patients with the following conditions [10, 11, 12] : • Complex fistulas (ie, high transsphincteric, suprasphincteric, extrasphincteric) or multiple fistulas • Recurrent fistulas after previous fistulotomy • Anterior fistulas in female patients • Poor preoperative sphincter pressures • Patients with Crohn disease or patients who are immunosuppressed Single-stage seton (cutting): Pass the seton through the fistula tract around the deep external sphincter after opening the skin, subcutaneous tissue, internal sphincter muscle, and subcutaneous external sphincter muscle. The seton is tightened down and secured with a separate silk tie. With time, fibrosis occurs above the seton as it gradually cuts through the sphincter muscles and essentially exteriorizes the tract. The seton is tightened on subsequent office visits until it is pulled through over 6-8 weeks. A cutting seton can also be used without associated fistulotomy. Recurrence and incontinence are important factors to consider when this technique is employed. The success rates for cutting setons range from 82-100%; however, long-term incontinence rates can exceed 30%. [13,14, 15] Two-stage seton (draining/fibrosing): Pass the seton around the deep portion of the external sphincter after opening the skin, subcutaneous tissue, internal sphincter muscle, and subcutaneous external sphincter muscle. Unlike the cutting seton, the seton is left loose to drain the intersphincteric space and to promote fibrosis in the deep sphincter muscle. Once the superficial wound is healed completely (2-3 months later), the seton-bound sphincter muscle is divided. Two studies (74 patients combined) supported the two-stage approach with a 0-nylon seton. Once wound healing is complete, the seton is removed without division of the remaining encircled deep external sphincter muscle. The researchers reported eradication of the fistula tract in 60-78% of cases. Mucosal Advancement Flap: A mucosal advancement flap is reserved for use in patients with chronic high fistula but is indicated for the same disease process as seton use. [1,16, 17] Advantages include a one-stage procedure with no additional sphincter damage. A disadvantage is poor success in patients with Crohn disease or acute infection. This procedure involves total fistulectomy, with removal of the primary and secondary tracts and completes excision of the internal opening. A rectal mucomuscular flap with a wide proximal base (two times the apex width) is raised. The internal muscle defect is closed with an absorbable suture, and the flap is sewn down over the internal opening so that its suture line does not overlap the muscular repair. Plugs and Adhesives: Advances in biotechnology have led to the development of many new tissue adhesives and biomaterials formed as fistula plugs. By their less-invasive nature, these therapies lead to decreased postoperative morbidity and risk of incontinence, but long-term data are lacking for eradication of disease, especially in complex fistulas, which carry high recurrence rates. [18, 19, 17] Reported series exist of fibrin glue treatment of fistula-in-ano, with 1-year follow-up showing recurrence rates approaching 40-80%. [20, 21,22] The Surgisis fistula plug has also had mixed long-term results in direct clinical trials. [23, 24, 25] Early success rates have been reported for newer materials, such as acellular dermal matrix and the bioabsorbable Gore Bio-A fistula plug, in low fistulas and good animal model data. [26] Assessment of long-term success rates with plug techniques for complex disease will be based on further data from randomized trials. In a randomized, controlled study designed to evaluate the efficacy and safety of the anal fistula plug in patients with fistulizing anoperineal Crohn disease, Senéjoux et al did not find the plug to be superior to seton removal for achieving fistual closure, regardless of whether the fistula was simple or complex. [27] A combined sphincter-sparing repair that includes both an anal fistula plug and a rectal advancement flap has been proposed for the treatment of transsphincteric fistula-in-ano. [28] LIFT Procedure: Ligation of the intersphincteric fistula tract (LIFT) is a sphincter-sparing procedure for complex transsphincteric fistulas first described in 2007. It is performed by accessing the intersphincteric plane with the goal of performing a secure closure of the internal opening and by removing the infected cryptoglandular tissue. [29] The intersphincteric tract is identified and isolated by performing meticulous dissection through the intersphincteric plane after making a small incision overlying the probe connecting the external and internal openings. Once isolated, the intersphincteric tract is hooked with a small right-angle clamp, and the tract is ligated close to the internal sphincter and then divided distal to the point of ligation. Hydrogen peroxide is injected through the external opening to confirm the division of the correct tract. The external opening and the remnant fistulous tract are curetted to the level of the proximity of the external sphincter complex. Finally, the intersphincteric incision is loosely reapproximated with an absorbable suture. The curettaged wound is left opened for dressing.[29,30,31] Because of its relative novelty, LIFT has not been extensively researched. In a randomized trial of 39 patients with complex fistula-in-ano who had failed previous procedures and were treated with LIFT technique, success rates were comparable to those seen with the anorectal advancement flap technique. [32] The probability of recurrence at 19 months was 8% for the LIFT technique versus 7% for the anorectal advancement flap. Time to return to work was shorter in the LIFT group (1 vs 2 wk), but there was no difference in incontinence scores. [32] Further randomized surgical trials are needed to determine whether this technique is a viable—or, possibly, a better—alternative to the other previously mentioned procedures for the treatment of fistula-in-ano. Diversion: In rare cases, the creation of a diverting stoma may be indicated to facilitate the treatment of a complex persistent fistula-in-ano. The most common indications include, but are not limited to, patients with perineal necrotizing fasciitis, severe anorectal Crohn disease, reoperative rectovaginal fistulas, and radiation-induced fistulas. Fecal diversion alone is effective in these select patients to control sepsis and symptoms; however, long-term success rates after reanastomosis are low because of recurrence from the underlying disease. Thus, this approach should be avoided unless the underlying fistula-in-ano disease process is repaired or has healed completely, which is unlikely. Postoperative Care: After the operation, most patients can be treated in an ambulatory setting with discharge instructions and close follow-up care. Sitz baths, analgesics, and stool-bulking agents (eg, bran and psyllium products) are used in follow-up care. Complications: Early postoperative complications may include the following: • Urinary retention • Bleeding • Fecal impaction • Thrombosed hemorrhoids Delayed postoperative complications may include the following: • Recurrence • Incontinence (stool) • Anal stenosis - The healing process causes fibrosis of the anal canal; bulking agents for stool help to prevent narrowing • Delayed wound healing - Complete healing occurs by 12 weeks unless an underlying disease process is present (ie, recurrence, Crohn disease) Postoperative rates of recurrence and incontinence vary according to the procedure performed, as follows: • Standard fistulotomy - The reported rate of recurrence is 0-18%, and the rate of any stool incontinence is 3-7% • Seton use - The reported rate of recurrence is 0-17%, and the rate of any incontinence of stool is 0-17% • Mucosal advancement flap - The reported rate of recurrence is 1-17%, and the rate of any incontinence of stool is 6-8% [16] Long-Term Monitoring: Frequent office visits within the first few weeks help to ensure proper healing and wound care. It is important to ensure that the internal wound does not close prematurely, causing a recurrent fistula. Digital examination findings can help distinguish early fibrosis. Wound healing usually occurs within 6 weeks.

A splenectomy is removal of the spleen. It is usually needed to treat blood disorders, injury to the spleen from trauma, or when the spleen becomes too pig. The surgery is done under general anaesthetic and can be either keyhole or open. Short term complications that can happen are bleeding, injury to nearby organs, and infection of the surgical scar. The biggest long-term complication is infection, as the spleen is not there anymore to develop immune cells. Vaccination should be given beforehand, and antibiotics should be given after to lower the risk of getting an infection.

Mr Usman Jaffer explains that the recovery time after repairing an abdominal aortic aneurysm (AAA) mainly depends on whether you have endovascular repair (EVAR) or open repair. With an endovascular repair, the recovery time is usually quicker. You could expect to be discharged home in a day or two if there are no complications and get back to normal activities in a few days. It is very unlikely you will need to stay in intensive care. An open repair is a major surgery so you should expect to be in hospital for about a week and slowly getting back to normal activities over a period of about 6 weeks. You will probably need to stay in an intensive care or a high dependency unit at least the night after the operation.

Feeling chest pain can be caused by a large number of possible causes. When you see your healthcare providers they will work thorough a list of possible causes based on your individual risks and how your pain can be categories. Chest pain can be sudden in onset or something that has come on gradually. It can be different locations depending on its cause. Some causes need urgent attention and others can be managed with less urgency. Due to the concern of missing urgent causes of chest pain, often patients are seen in a 'Rapid Access Chest Pain clinic' setting.
