The exception may be an interior opening that is greater than 3cm from the dentate line discount 100caps gasex visa. Goodsall’s rule is of particular assistance in identifying the direction of the tract (Fig discount gasex 100caps without a prescription. Fissures result from forceful dilation of the anal canal, most com- monly during defecation. The pain associated with the initial bowel movement is great, and the patient therefore ignores the urge to defe- cate for fear of experiencing the pain again. The pain is often tearing or burning, worse during defecation, and subsides over a few hours. Anoscopy and proctosigmoidoscopy should be deferred until healing occurs or the procedure can be performed under anesthesia. Eisenstat in the initial evaluation of a patient with a ﬁssure, they must be per- formed during a subsequent visit because the presence of associated anorectal malignancy or inﬂammatory bowel disease must be excluded. Ulcers occurring off the midline or away from the mucocutan- eous junction are suspect. Treatment using stool softeners, bulk agents, and sitz baths is suc- cessful in healing 90% of anal ﬁssures. Patients are instructed to soak in a hot bath and contract the sphincters to identify the muscle in spasm and then focus on relaxing that muscle. Botox inﬁltration into the inter- nal sphincters may be effective in the treatment of anal ﬁssures. Lateral internal sphincterotomy is the procedure of choice for many surgeons after conservative measures have failed. Hemorrhoids Patients with perianal pathology often present or are referred with a chief complaint of “hemorrhoids. Those individuals with painless bleeding due to hemorrhoids must be distinguished from those with bleeding from colorectal malignancy, inﬂammatory bowel disease, diverticular disease, and adenomatous polyps. Rectal prolapse must be distin- guished from hemorrhoids because it is safe to band a hemorrhoid but not a prolapsed rectum. Hemorrhoidal tissues are part of the normal anatomy of the distal rectum and anal canal. The disease state of “hemorrhoids” exists when the internal complex becomes chronically engorged or the tissue pro- lapses into the anal canal as the result of laxity of the surrounding con- nective tissue and dilatation of the veins. External hemorrhoids may thrombose, leading to acute onset of severe perianal pain. Internal hemorrhoids may have two main pathophysiologic mecha- nisms seen in two distinct but not exclusive groups: older women and younger men. Internal hemorrhoids originate above the dentate line and are lined with insensate rectal columnar and transitional mucosa. In older women, the pathophysiologic mechanism may be related to earlier pregnancy or chronic straining, which leads to vascular engorgement and dilatation, resulting in stretching and disruption of the supporting connective tissue surrounding the vascular channels. Another suggested pathologic mechanism, and the one that may be more important in younger men, is that of increased resting pressures within the anal canal, leading to decreased venous return.
Has he experienced decreased force of urinary flow cheap gasex 100 caps without a prescription, decreased ability to initiate voiding gasex 100caps fast delivery, urgency buy cheap gasex 100 caps online, frequency 100caps gasex with mastercard, nocturia order gasex 100 caps with amex, dysuria cheap 100 caps gasex overnight delivery, urinary retention, hematuria? Does the patient report associated problems, such as back pain, flank pain, and lower abdominal or suprapubic discomfort? Has the patient experienced erectile dysfunction or changes in frequency or enjoyment of sexual activity? This information helps determine how soon the patient will be able to return to normal activities after prostatectomy. Preoperative Nursing Diagnoses 251 Anxiety about surgery and its outcome Acute pain related to bladder distention Deficient knowledge about factors related to the disorder and the treatment protocol Postoperative Nursing Diagnoses Acute pain related to the surgical incision, catheter placement, and bladder spasms Deficient knowledge about postoperative care and management Collaborative Problems/Potential Complications Based on the assessment data, the potential complications may include the following: Hemorrhage and shock Infection Deep vein thrombosis Catheter obstruction Sexual dysfunction Planning and Goals The major preoperative goals for the patient may include reduced anxiety and learning about his prostate disorder and the perioperative experience. The major postoperative goals may include maintenance of fluid volume balance, relief of pain and discomfort, ability to perform self-care activities, and absence of complications. Preoperative Nursing Interventions Reducing Anxiety The patient is frequently admitted to the hospital on the morning of surgery. Because contact with the patient may be limited before surgery, the nurse must establish communication with the patient to assess his understanding of the diagnosis and of the planned surgical procedure. The nurse clarifies the nature of the surgery and expected postoperative outcomes. In addition, the nurse familiarizes the patient with the preoperative and postoperative routines and initiates measures to reduce anxiety. Because the patient may be sensitive and embarrassed discussing problems related to the genitalia and sexuality, the nurse provides privacy and establishes a trusting and professional relationship. Guilt feelings often surface if the patient falsely assumes a cause-and-effect relationship between sexual practices and his current problems. Relieving Discomfort If the patient experiences discomfort before surgery, he is prescribed bed rest, analgesic agents are administered, and measures are initiated to relieve anxiety. If he is hospitalized, the nurse monitors his voiding patterns, watches for bladder distention, and assists with catheterization if indicated. An indwelling catheter is inserted if the patient has continuing urinary retention or if laboratory test results indicate azotemia (accumulation of nitrogenous waste products in the blood). The catheter can help decompress the bladder gradually over several days, especially if the patient is elderly and hypertensive and has diminished renal function or urinary retention that has existed for many weeks. For a few days after the bladder begins draining, the blood pressure may fluctuate and renal function may decline. If the patient cannot tolerate a urinary catheter, he is prepared for a cystostomy (see 252 Chapters 44 and 45). Providing Instruction Before surgery, the nurse reviews with the patient the anatomy of the affected structures and their function in relation to the urinary and reproductive systems, using diagrams and other teaching aids if indicated. The nurse explains what will take place as the patient is prepared for diagnostic tests and then for surgery (depending on the type of prostatectomy planned). The nurse also describes the type of incision, which varies with the surgical approach (directly over the bladder, low on the abdomen, or in the perineal area; in the case of a transurethral procedure, no incision will be made), and informs the patient about the likely type of urinary drainage system, the type of anesthesia, and the recovery room procedure. The nurse explains procedures expected to occur during the immediate perioperative period, answers questions the patient or family may have, and provides emotional support. In addition, the nurse provides the patient with information about postoperative pain management. Preparing the Patient If the patient is scheduled for a prostatectomy, the preoperative preparation described in Chapter 18 is provided. An enema is usually administered at home on the evening before surgery or on the morning of surgery to prevent postoperative straining, which can induce bleeding. Postoperative Nursing Interventions Maintaining Fluid Balance During the postoperative period, the patient is at risk for imbalanced fluid volume because of the irrigation of the surgical site during and after surgery. With irrigation of the urinary catheter to prevent its obstruction by blood clots, fluid may be absorbed through the open surgical site and retained, increasing the risk of excessive fluid retention, fluid imbalance, and water intoxication. The urine output and the amount of fluid used for irrigation must be closely monitored to determine whether irrigation fluid is being retained and to ensure an adequate urine output.

Eventually, she was diag- nosed as having cholecystitis with cholelithiasis and underwent cholecystectomy. This pain followed a crescendo pattern and peaked several weeks ago, at a time when family stress was also at its climax. It does not cause any nausea or vomiting, does not trigger any urge to defecate, and is not alleviated by passage of flatus. While referring to Figure 6–3, describe the location of the gallbladder in relation to the liver. How does the patient’s most recent postoperative episode of discomfort (pain) differ from the initial pain she described? Use a medical dictionary such as Taber’s Cyclopedic Medical Dictionary, the appendices of this book, or other resources to define each term. Then review the pronunci- ations for each term and practice by reading the medical record aloud. She was given nasal oxygen at 3 liters per minute and monitored with a pulse oximeter throughout the procedure. Through a previously inserted intravenous line, the patient was sedated with a total of 50 mg of Demerol intravenously plus 4 mg of Midazolam intravenously throughout the procedure. The Fujinon computed tomography scan videoendoscope was then readily introduced and the following organs evaluated. A representative biopsy was obtained from the gastric antrum and submitted to the pathology laboratory.

Sutyak Rigid esophagoscopy rarely is indicated and remains a tool used primarily in the operating room when cricopharyngeal or cervical esophageal lesions prevent passage of a ﬂexible scope gasex 100caps overnight delivery, when biopsies deeper than those obtainable with ﬂexible endoscopy are needed to stage disease and plan resective therapy order gasex 100 caps on-line, and for the removal of foreign bodies buy 100caps gasex mastercard. Manometry is indicated when a motor abnormality is suspected on the basis of symptoms of dysphagia or odynophagia and when the barium swallow and esophagoscopy do not show an obvious structural mmHg Figure 12 buy discount gasex 100 caps. Manometry is essential to conﬁrm diagno- sis of primary esophageal motility disorders such as achalasia buy gasex 100 caps visa, diffuse esophageal spasm cheap gasex 100 caps online, nutcracker esophagus, and hypertensive lower esophageal sphincter. It may be useful in identifying nonspeciﬁc esophageal motility disorders and motility abnormalities secondary to systemic diseases of scleroderma, dermatomyositis, polymyositis, or mixed connective tissue disease. Esophageal manometry is performed by passing a catheter nasally into the stomach while measuring pressure through a pressure- sensitive transducer. Assessment of Esophageal Exposure to Gastric Content Ambulatory 24-hour esophageal pH monitoring has become the stan- dard for quantitating esophageal exposure to acidic content and relat- ing symptoms to esophageal pH. While the patient continues a normal routine, including eating and the usual activities, the pH is recorded throughout a 24-hour cycle. The patient maintains a diary, recording body positions, meals, and symp- toms, so that esophageal pH can be correlated with symptoms. At the completion of the test, the results are tallied and compared to normal values for esophageal acid exposure. The study can be performed in the presence or absence of acid-reducing medications in order to deter- mine the effectiveness of the medication. Twenty-four-hour pH monitoring is indicated for patients who have typical symptoms of gastroesophageal reﬂux, for patients for whom other diagnostic tests are equivocal, for patients with atypical symptoms of gastroesophageal reﬂux such as noncardiac chest pain, persistent cough, wheezing, and unexplained laryngitis, or for patients with previously failed esophageal or gastric surgery with recurrent symptoms. Provocation of Esophageal Symptoms Three tests previously were used to identify a relationship between symptoms and esophageal exposure to acid or motor abnormalities: the acid perfusion test (Bernstein, 0. Ambulatory pH testing and esophageal manometry have made these tests primarily of historical and academic interest. Sutyak Evaluation of Gastric Motility and Biliary Disease In evaluating a patient with esophageal symptoms, it also is impor- tant to consider the impact of gastroduodenal dysfunction on lower esophageal function as well as other common gastrointestinal prob- lems that can mimic esophageal disease. A gastric emptying study and/or right upper quadrant ultrasound may be indicated in patients with symptomatology suggestive of esophageal disorders in order to rule out gastroparesis or gallbladder disease. Speciﬁc Conditions Tumors Malignant Esophageal Tumors Overview: The majority of esophageal neoplasms are malignant. Esophageal cancer is among the top 10 leading causes of cancer deaths in the United States and is increasing in incidence. Although squa- mous cell carcinoma previously accounted for 90% to 95% of reported esophageal malignancies, the incidence of adenocarcinoma has increased dramatically in the past two decades and now accounts for at least 40% of all malignancies. This relative change may reﬂect the increased use of ﬂexible endoscopy and closer surveillance of asymp- tomatic patients who are at risk of developing esophageal carcinoma. Squamous cell carcinomas are distributed equally among the upper, middle, and lower thirds of the esophagus. Alcohol consumption and tobacco use are well-established factors for the development of esophageal carcinoma. Other risk factors for esophageal cancer include achalasia, radiation esophagitis, caustic esophageal injury, infection (human papilloma virus), Plummer– Vinson syndrome, leukoplakia, esophageal diverticula, ectopic gastric mucosa, and the inherited condition of familial keratosis palmaris et plantaris (tylosis). Diagnosis: The vast majority of esophageal carcinomas are clinically occult and present well after disease progression prevents cure. Most patients experience dysphagia an average of 2 to 4 months before presentation. Unfortunately, dysphagia almost uniformly indicates extensive disease and incurability. The initial study should be a barium swallow; this most frequently reveals distinct mucosal irregularity, stricture, a shelf in the lower esophagus, or rigidity. Upper esophageal endoscopy allows visualiza- tion of the affected area and biopsy to conﬁrm the diagnosis.
