Although there are historical data that attempt to compare resistance of surgical wounds to infection based on the use of Wound Irrigation a steel knife versus electrocautery, few data support one technique or the other. Some attention has been also given to Adequate intraoperative irrigation of the wound minimizes proper suture usage. The guiding message in this regard the bacterial inoculum and has been shown to decrease post- should be to limit suture use to a necessary minimum, avoid- operative infection. It has long been customary to pour sev- ing undue tissue tension and strangulation. Localizing Contamination Frequent irrigation with 200 ml of saline followed by aspira- tion is a rational approach to washing out bacteria spilled Adequate exposure with proper retraction is essential for con- into the field.

The main goal of such management is to prevent potentially devastat- ing complications, such as fasciitis. Delayed primary closure, within 4–6 postoperative days, results in fewer wound infections than primary closure after contaminated operations. Many surgeons believe that attempted delayed primary closure is a reasonable “compro- mise” between healing by secondary intention and primary Fig. When successful, delayed primary closure avoids large wounds that require labor-intensive, potentially expen- bacterial inoculum, wound irrigation rinses the operative sive care. Wound Dressings Other Considerations Wound dressings are a means to protect the wound and a mechanism for absorbing wound drainage. Wounds that are Drains are used when a localized collection of pus (a well- to heal by secondary intention or delayed primary closure formed abscess) is found or when there is concern over con- require a wound dressing.

These changes alongwith stasis dermatitis which produces brawny oedema purchase 20mg cialis super active visa erectile dysfunction 40s, cutaneous atrophy and pigmentation ultimately lead to tissue death and ulceration order 20mg cialis super active amex erectile dysfunction what kind of doctor. There may be associated varicose veins 20 mg cialis super active fast delivery erectile dysfunction 23 years old, but this condition is mainly due to deep vein abnormalities and incompetent perforators generic cialis super active 20 mg line erectile dysfunction and testosterone injections. All these are usually seen on the medial aspect of the leg just above the ankle posterior and superior to the medial malleolus. The venous ulcers are characteristically shallow with surrounding rims of bluish discolouration and erythema. Indications for this operation are — (i) severe varicosities, (ii) moderate to severe symptoms of varicosities and (iii) presence of venous ulcers even with aggressive conservative management. It is particularly effective if performed before the patient has developed an ulcer. Longitudinal incision is made 1 cm behind and parallel to the posterior subcutaneous tibial border. The margins of deep fascia are now elevated and the perforators are ligated flush to the deep fascia and then divided. For iliofemoral occlusion the contralateral saphenous vein is passed suprapubically and anastomosed to the affected side. For femoropopliteal occlusion, the obstructed segment can be by-passed by anastomosis of saphenous vein to the popliteal- tibial trunk at the level of the knee. Gradually brawny oedema appears distally due to coagulation of lymph within the lymphatics. Acute lymphangitis is more frequently caused by Haemolytic Streptococci, though it can also occur due to Staphylococcal infections. When infection occurs in the distal limb with organisms mentioned above, such infection spreads through the lymphatics to the regional lymph nodes. This is often associated with enlarged and tender regional lymph nodes which indicate their involvement. Since beta-haemolytic streptococci are the common infecting organisms, penicillin is the antibiotic of choice, unless culture and sensitivity tests approve other antibiotic. Incision is almost always contraindicated unless there is definite signs of purulent accumulation e. The clinical importance of this condition lies in the fact that acquired lymphoedema may be precipitated due to this condition. These tumours are often seen in the area of the jugular buds in the neck, though these are also seen in the axilla, shoulder and groin. Localized cluster of dilated lymph sacs in the skin and subcutaneous tissue which cannot connect into the normal lymph system grows into lymphangioma or benign neoplasm of lymphatics. These are typically seen on the innerside of the thigh, on the shoulder or in the axilla. Lymphangiography reveals that the lesion is separate from the main lymphatic system. Treatment is excision, when lymphangiography confirms that the lesion is separate from the main lymphatic. These are often found in the face, mouth, lips (causing enormous enlargement of the lips or macrocheilia) and in the tongue (a common cause of macroglossia). Remaining 5% are found scattered in different parts of the body — in the mediastinum, groin, pelvis and even retroperitoneum. Peculiarly a few cervical cystic hygromata may have mediastinal extension extending as far as the diaphragm. In the depth the locules are quite big and towards the surface the locules become smaller and smaller in size. The swelling is mainly painless, though occasionally it may be painful when it becomes infected. Regional lymph nodes usually do not enlarge until and unless the lesion gets infected. In the neck the lesion is removed under general endotracheal anaesthesia using transverse incision. The cyst wall often lies close to the carotid artery, jugular vein, vagus nerve and brachial plexus. It must be remembered that the excision must be complete to avoid any chance of recurrence. This lesion is a developmental anomaly and is not a malignant tumour, so this condition is rarely associated with recurrence. But as for all cysts, if cyst wall is left behind fluid may reaccumulate to cause reappearance of the swelling. That is why macroscopically identifiable cystic wall should be dissected away to prevent recurrence. Kinmoth described sclerosing treatment for this lesion in adults with apparent satisfactory result. It is occasionally seen in long standing cases of primary or secondary lymphoedema of the extremities. Later on a skin nodule is seen, on which ulcers with crusting are noticed which gradually progress to necrosis. The disease is characterized by brawny lymphoedema of both legs, sometimes of the genitalia, arms and even face. It is often associated with wide range of lymphatic abnormalities on lymphangiography. This can be divided into three clinical subgroups according to the age of onset of the swelling. This variety is comparatively rare and occurs in about 10% of all cases of primary lymphoedema. In primary lymphoedema there is some developmental fault in the lymphatic system and a family history is found in about l/5th cases. Lymphangiography has demonstrated 3 basic types of malformation of this disease — (a) Aplasia of the subcutaneous lymph trunks in the limbs is found in 13% of patients. Formed lymphatic vessels are absent, but there are haphazardly arranged lymph spaces with no attempt to form lymphatic channels. This is a severe malformation and is often associated with the congenital variety. The commonest defect in this group is presence of a solitary lymph vessel, which ascends the limb without normal bifurcation and branching. This may be termed solitary hypoplasia, which may extend upto the knee or even upto the groin. In a small number of patients hypoplasia may affect the lymph nodes in the groin while the lymph trunks remain normal. In this condition the subcutaneous tissues are filled with dilated and tortuous lymphatics which are incompetent and allow retrograde reflux of lymph. The varicose state may extend proximally to involve the pelvic and even para-aortic lymph trunks.
Only treatment of a few polyps which are more often seen in the rectum is described below buy 20mg cialis super active free shipping erectile dysfunction doctors in south jersey. Usually it possesses a long pedicle and the tumour can be delivered through the anus buy discount cialis super active 20mg online erectile dysfunction after age 40. If the tumour is high up in the rectum or the pedicle is short cialis super active 20 mg visa erectile dysfunction cause of divorce, a snare may be used generic cialis super active 20 mg without a prescription erectile dysfunction caused by spinal cord injury. Yet when an adenomatous polyp is detected, it should be removed, however little chance of malignant transformation there may be. When there is a long pedicle and the polyp can be delivered through the anus, the pedicle is transfixed and the tumour is excised. When the-growth has small pedicle or is higher up, the tumour is removed with a snare through sigmoidoscope. In case of sessile adenoma the tumour can be removed either by submucous dissection per annum or the tumour may be fulgurated with an insulated electrode passed through a sigmoidoscope. The malignant change can be assessed by palpation with the finger — any hard area should be assumed to be malignant and should be biopsied. This tumour discharges mucus and rarely it is so profuse, which is high in potassium, as to cause electrolyte imbalance and fluid loss. Small tumours may be excised by submucous dissection per annum or by sleeve resection from above. In this method a large operating sigmoidoscope is introduced, the rectum is distended with C0 (carbon dioxide) insufflation. The image of the operation field can be displayed on a monitor through2 a camera inserted via the sigmoidoscope. The lesion is excised with specially designed instrument observing the monitor screen. It is also a submucous tumour which appears as a constricting lesion at the rectosigmoid junction. Diagnosis is not difficult as dysmenorrhoea with rectal bleeding is the only peculiar symptom of this condition. On sigmoidoscopy the lesion is seen at the rectosigmoid junction as reddish projection into the lumen with the mucous membrane intact. Treatment is contraceptive pill which inhibits ovulation and amelioration of symptoms. Anterior resection or sphincter conserving operation is well suited for this purpose. Three varieties of adenocarcinoma can be seen according to their differentiation, (i) Well differentiated variety, (ii) averagely differentiated variety and (iii) anaplastic or undifferentiated variety. It may appear either from mucoid degeneration of adenocarcinoma or as a primary mucoid carcinoma. The mucus lies within the cell displacing the nucleus to the periphery like a signet ring appearance. Primary colloid carcinoma grows rapidly, metastasises early and possesses a poor prognosis. Longitudinal spread is restricted to a few centimetres except in anaplastic tumours. It takes about 6 months to involve1A th of the circumference and about 1 Vi to 2 years to involve the whole circumference of the rectum. Then the spread involves the full thickness of the rectum but is still limited by the fascia propria (perirectal fascia). Growth takes a long time to penetrate fascia propria and it is rare before 18 months from the commencement of the disease. Once the fascia propria is penetrated, the growth is liable to involve the adjoining structures which are as follows : Anteriorly — in males the prostate, seminal vesicles and the bladder; in females the vagina and the uterus. Laterally— the ureter may be involved in either sex causing secondary hydronephrosis. As soon as the muscles of the rectum are involved, there is chance of lymphatic spread. It must be remembered that enlargement of the draining lymph nodes does not mean that it is secondarily involved. Enlargement of lymph nodes may occur from secondary infection which is not infrequent. Next lymph nodes to be affected are the pararectal nodes of Gerota (same as paracolic nodes). The intermediate nodes are situated along the lower part of the superior rectal artery and the main nodes are at the origin of the inferior mesenteric artery. The peculiarity of the lymphatic spread of rectal carcinoma is that the spread is mainly upwards as the lymphatics move mainly in that direction. Carcinoma ofthe rectum above the peritoneal reflection spreads in an upward direction first involving the intermediate nodes and then the main nodes. Carcinoma below the peritoneal reflection to within 1 to 2 cm ofthe anal orifice spreads mainly in the upward direction but the first nodes involved are the pararectal nodes of Gerota, then the intermediate nodes and lastly the main nodes. Carcinoma between 4 to 8 cm from the anus spreads mainly in the lateral direction along the lymphatics that accompany the middle rectal vein, as this portion of the rectum is supplied by the middle rectal artery. Carcinoma involving 1 to 2 cm of the anal orifice usually spreads downwards to the inguinal group of lymph nodes as the area of anal canal below the dentate line is drained into the inguinal group of lymph nodes. Widespread and atypical lymphatic permeation may occur in case of anaplastic carcinoma. Only anaplastic carcinoma and rapidly growing tumours in younger patients are liable to spread via blood. The first organ to be affected by venous spread is the liver through inferior mesenteric vein. Occasionally spread may occur through systemic veins like middle rectal or inferior rectal veins and may metastasise to the lungs, spines, adrenals etc. Probably more important is the histological grading which will indicate the type of cancer by examining biopsy specimen under microscope. A highly malignant tumour even if detected in early stage will carry worse prognosis than a well differentiated tumour in rather late clinical stage. Stage B — The growth has extended beyond the rectal wall but no involvement of regional lymph nodes. Stage C — The growth has extended beyond the rectal wall and the regional lymph nodes are involved. This stage can be further subdivided into Stage Cl where the local pararectal lymph nodes are only involved and Stage C2 where intermediate and main nodes are involved. T1 : Involvement of the mucous and submucous coat but the muscular wall is not involved. T3 : Involvement of all layers of the colonic wall including serosa, which is judged by irregularity.
