Chassin† Indications The operative technique for resecting the left colon and for the anastomosis is similar to that described for left Elective colectomy for carcinoma but with a number of important Recurrent diverticulitis exceptions.

In most cases, it is not necessary to elevate the rectum Emergent from the presacral space, as this area is rarely the site of Spreading or generalized peritonitis diverticula. Though it is important to remove the greatest concentra- tion of diverticula, in elderly patients, it is not necessary Preoperative Preparation to perform an extensive colectomy just because there are some innocent diverticula in the ascending or transverse See Chap. The site selected for anastomosis should be free of diverticula and gross muscle hypertrophy. Primary anastomosis should be performed only if the Operative Strategy proximal and distal bowel segments selected for anasto- mosis are free of cellulitis and of marked muscle hyper- This operation is used primarily for diverticular disease. If an abscess has been encountered in the pelvis, may also be used during emergency surgery for lower gas- so that the anastomosis would lie on the wall of an evacu- trointestinal bleeding. In the latter case, it is crucial to local- ated abscess cavity, it is wise to delay the anastomosis for ize the bleeding source before surgery. When this dissection has been completed, Incision the sigmoid is free down to the promontory of the sacrum. Make a midline incision from the upper epigastrium to the Some surgeons will have ureteral stents placed before sur- pubis. Initiate the dissection in the region of the upper descending colon by incising the peritoneum in the paracolic gutter. This serially between Kelly hemostats at a point no more than allows you to begin the dissection in an area that is relatively 4–6 cm from the bowel wall (Fig. Continue the incision in the paracolic division at a point on the left colon that is free of pathology. Continue the dissection to the At this point, to safeguard the left ureter from damage, rectosigmoid. Remove the specimen after applying Allen it is essential to locate it in the upper portion of the clamps. In rare cases, it is necessary to make the anastomosis at a lower level, where the ampulla of the rectum is signiﬁ- cantly larger in diameter than the proximal colon. In that case, a side-to-end Baker anastomosis is preferable, as described in Chap. Abdominal Closure In the absence of intra-abdominal or pelvic abscesses, close the abdomen in the useful fashion (see Chap. Primary Resection with End Colostomy and Mucous Fistula If it is decided to delay the anastomosis for a second stage, it is not necessary to excise every bit of inﬂamed bowel, as this frequently requires a Hartmann’s pouch at the site of the rec- tosigmoid transaction and makes the second stage more dif- ﬁcult than if a mucous ﬁstula can be constructed. In almost every case, proper planning of the operation permits exteri- orization of the distal sigmoid as a mucous ﬁstula, which can be brought out through the lower margin of the midline inci- sion after a De Martel clamp or stapled closure is secured Fig. If this is not feasible, staple the distal sigmoid and allow it to return to the pelvis as described in the next section. Divide the mesocolon to preserve the vascularity of the local drainage is associated with a mortality rate of more mucous ﬁstula or Hartmann’s pouch.

Decreased oxygen saturation would suggest emphysema buy cymbalta us anxiety symptoms versus heart symptoms, pulmonary fibrosis discount cymbalta 40 mg free shipping anxiety symptoms unsteadiness, or cardiovascular disorder cymbalta 30mg mastercard anxiety symptoms stuttering. An increase in the blood erythropoietin would suggest an erythropoietin-secreting tumor such as renal carcinoma or pheochromocytoma. A normal or decreased erythropoietin would point to polycythemia vera, heavy cigarette smoking, or methemoglobinemia. A hematology consult would be wise before undertaking any of the more expensive studies. The presence of these symptoms would suggest diabetes mellitus and hyperthyroidism. The presence of massive polyuria suggests diabetes insipidus or psychogenic polydipsia. The presence of mild polyuria should suggest chronic renal failure, renal tubular acidosis, hyperparathyroidism, and febrile illnesses. Also, a 24-hour urine collection for calcium may be done to help diagnose this condition. Microscopic examination of the urinary sediment will help diagnose renal disease, as will renal biopsies. The Hickey–Hare test and monitoring intake and output before and after vasopressin (Pitressin) will be useful in differentiating pituitary diabetes insipidus from nephrogenic diabetes insipidus. An endocrinologist should be consulted before ordering these expensive diagnostic tests. The presence of these symptoms would suggest diabetes mellitus or hyperthyroidism. This symptom would indicate that the patient has an insulinoma, Cushing’s disease, or idiopathic obesity. These symptoms would signal that the polyphagia is related to bulimia, hysteria, or other psychic disorder. If an insulinoma is suspected, plasma insulin or C-peptide levels may be done, or the patient may be hospitalized for a 72-hour fast with frequent blood sugar determinations. If hyperthyroidism, diabetes mellitus, insulinoma, and intestinal disorders have been ruled out, a referral to a psychiatrist would be indicated. Massive polyuria is usually because of pituitary or nephrogenic diabetes insipidus and psychogenic polydipsia. The presence of polyphagia and polydipsia suggests the possibility of diabetes mellitus and hyperthyroidism. The presence of a mild polyuria suggests chronic nephritis, renal tubular acidosis, hyperparathyroidism, Fanconi’s syndrome, and mild diabetes mellitus. The presence of glycosuria suggests diabetes mellitus, hyperthyroidism, and Fanconi’s syndrome. If renal disease is suspected, the urinary sediment should be examined microscopically and renal biopsy may be necessary. An endocrinologist and nephrologist should be consulted before undertaking expensive diagnostic tests. A soft popliteal swelling may be an abscess, varicose vein, Baker’s cyst, popliteal aneurysm, or swollen bursa. A firm popliteal swelling may be an osteosarcoma, periostitis, giant cell tumor, exostoses, lymphadenitis, lipoma, or fibroma. Masses that are connected to the bone are more likely exostoses, osteosarcomas, periostitis, or giant cell tumors. However, it is more cost-effective to seek an orthopedic consultation before ordering these tests or undertaking aspiration of the swelling. Children may take birth control pills early in life, and young boys may want to take anabolic steroids to increase their muscular mass. These findings would suggest a brain tumor, and a pinealoma is one that should be excluded. The presence of an adnexal mass would suggest a granulosa cell tumor or arrhenoblastoma. The presence of an adrenal mass would suggest adrenocortical hyperplasia or tumor. It is best to consult an endocrinologist, urologist, or gynecologist before ordering these expensive diagnostic tests. Conditions more often associated with a thrill are ventricular septal defect, pulmonic stenosis, and the combination of the two that is found with tetralogy of Fallot.

Similar deformity with an undue anterior prominence just above the elbow in children is probably caused by supracondylar fracture purchase cymbalta without a prescription anxiety 12 step groups. The bones to be palpated are the lower part of the humerus purchase cymbalta 40 mg with visa anxiety 4th, the head of the radius purchase cymbalta without a prescription anxiety girl, upper part of the ulna, the olecranon process and the relative positions of 3 bony points viz. Besides these there are fracture-separation of the lateral condylar epiphysis and separation of medial epicondylar epiphysis in case of children and fractured capitulum in case of adult which should also be kept in mind. While examining the lower end of the humerus first one should palpate both the epicondyles of the humerus with the thumb and the four fingers of the clinician. If it seems that there is no condylar fracture or separation, the clinician with his other hand should hold the upper part of the humerus and the lower fragment is made to move with the fingers of this hand. Abnormal position of any epicondyle will suggest fracture separation of condylar epiphysis or fractured capitulum. Abnormal broadening of the lower end of the humerus with distortion of the condyles suggests T — or Y — shaped fracture. In both these circum stances there is no generalized swelling of the elbow, but there is localized Fig. The head of the radius can be best palpated in the lower part of the dimple just below the lateral condyle of the humerus when the forearm is pronated and supinated. In case of fracture of the radial head there will be tenderness and irregularity during rotation of the radius. Sometimes a referred pain can be elicited at the fracture site particularly at the neck and the upper part of the shaft of the radius by springing the radius (Fig. This is done by squeezing the radius and ulna together at the lower part of the forearm, when the patient will complain of pain in the upper end of the radius. While palpating the upper end of the radius one must also keep in mind the possibility of dislocation of the head of the radius. It may occur alone or may be associated with fracture-displacement of the upper third of the ulna either forwards (Monteggia fracture) or backwards (reversed Monteggia). The clinician should move his finger along the subcutaneous border of the ulna to detect any local bony irregularity or local bony tenderness to suggest a crack fracture of the ulna. Any obvious deformity in the ulna and an abnormal prominence of the displaced fragment suggest fracture of the upper end of the ulna with displacement. In these cases one must not forget to palpate the head of the radius as this is very often dislocated along with displaced fracture of Fig. Local bony irregularity with bony tenderness suggests a crack fracture of the olecranon. When the fracture is associated with separation, there will be gap in between the two fragments. Abnor mal projection of the olecranon process posteriorly suggests posterior dislocation of the elbow in adult and supracondylar fracture in children. In extended elbow these three bony points lie on a straight horizontal line but in flexed elbow they form a triangle which is neither isosceles nor equilateral but has the shortest side between the medial epicondyle and the olecranon and the longest between the two epicondyles. One should always compare the relative positions of these bony points with those of the sound side. When the olecranon process is pushed more posteriorly and a little above its usual position the case is one of posterior dislocation of the elbow. When both the epicondyles are more widely separated one should suspect a T- or Y - shaped fracture of the condyles. While testing the movements of pronation and supination, one should always keep the elbow of the patient flexed otherwise in extended elbow rotation of the humerus will give a false impression of these movements. In injury around the elbow the fracture which causes maximum complications is the supracondylar fracture of the humerus. Even if there is no recent injury to any of these nerves, there remains a chance of late (tardy) ulnar palsy. So one must examine for any neurological deficits that might be caused by such injury around the elbow. The brachial artery is commonly the victim either by thrombosis or spasm or kinking. This condition should be suspected if the patient complains of pain down the forearm after the fracture has been reduced and plastered. Only antero-posterior view may not be able to detect such injuries as fracture of olecranon, posterior dislocation of the elbow and even the supracondylar fracture without lateral displacement. While interpreting a skiagram of the elbow joint after injury one must have a clear conception of time of appearance, the size, the shape, the position and time of fusion of all the epiphyses in the region of the elbow.
