Dysphagia, substernal or epigastric distress, and regurgitation of food are important early symptoms in the diagnosis of carcinoma of the esophagus. Temporary remission in symptoms does not rule out esophageal cancer. The use of thick barium meal and routine thorough examination of the esophagus in upright and supine positions in all upper gastrointestinal roentgen studies, even though the clinical symptoms point to the upper abdomen, are of great importance.The spread of the cancer to both mediastinal and subdiaphragmatic lymph nodes makes transthoracic thoracolaparotomy the one approach which will permit the surgeon to perform a one-stage esophagogastrostomy, and to adequately evaluate and deal with cancerous tissue on both sides of the diaphragm. This one-stage procedure permits the patient to swallow normally after operation, and the costly and time-consuming uncertainties of the many-staged operations are avoided. The comfort which the operation gives to otherwise doomed patients, along with the improving postoperative mortality rate, offers new hope to those who have cancer of the esophagus. 相似文献

The principal purpose of the paper is to assess the role of the X-ray section of current radiation diagnosis in obtaining objective information and interpreting it in esophageal cancer. The study was methodically based on its serial studies, by comparing the data of clinical, radiation, and endoscopic diagnosis with those of morphological studies of the biopsy specimens taken at resection for cancer of the esophagus and the upper stomach, and histologically examined them in diseases running with the similar clinical symptoms. The complex of radiation techniques included traditional X-ray study (compact filling, double contrasting). A specially developed procedure that allowed physicians the opportunity to examine the cardioesophageal area in the fragmentary fashion was used during morphological studies. In cancer of the upper stomach, the lower esophageal segments were also involved in the process in 79.9%. It should be also noted that this number of observations includes some cases that clinical symptomatology and endoscopy strongly suggest cancer of the lower third of the esophagus. The authors have arrived at the conclusion that the present-day X-ray semiotics of esophageal diseases running with the similar clinical symptomatology permits their differential diagnosis just before the use of endoscopy and histology of biopsy specimens and that the unique advantage of radiation diagnosis over endoscopy is to specify the initial site of a tumor, namely, to detect primary gastric damage in cardioesophageal carcinoma. 相似文献

A new microsurgical alternative in reconstruction of the pharynx and cervical esophagus is reported. A trapezoidal forearm flap is fabricated into an inverted skin tube and placed in the pharyngoesophageal defect. Although microvascular anastomoses are required to revascularize the transferred forearm flap, the long and large nutrient vessels of the flap make anastomoses easy and reliable. None of our 12 patients demonstrated any necrosis of the transferred flap. This one-stage, less invasive operation for pharyngoesophageal reconstruction greatly benefits older persons, who are the more likely to be involved with pharyngoesophageal carcinomas. 相似文献

Summary Histological and ultrastructural observations of the digestive tract of eight-armed plutei of Dendraster excentricus are reported. The esophagus is divided into two regions. The uppermost is a narrow tube comprised of ciliated cells that assist in transporting food to the more bulbous lower esophagus where food particles are formed into a bolus prior to entering the stomach. The esophagus is surrounded by a network of smooth muscle fibers that are predominantly oriented circumferentially in the upper esophagus, and longitudinally in the lower esophagus. The musculature of the upper esophagus produces peristaltic contractions, whereas contractions of the muscle of the lower esophagus open the cardiac sphincter and force food from the lower esophagus into the stomach. Axons are associated with the ciliated cells and the muscles of the upper esophagus. The cardiac sphincter consists of a ring of myoepithelium, with cross-striated myofibrils oriented around the bases of the cells. The gastric epithelium is comprised of two cell types. Type I cells, which predominate, absorb and store nutrients, and may be the source of secreted digestive enzymes. Type II cells apparently phagocytize and intracellularly digest whole algal cells. The intestine is comprised of relatively unspecialized cells and probably functions primarily as a conductive tube for the elimination of undigested materials. 相似文献

Cancer of the upper stomach: current problems of its diagnosis 总被引:4,自引:0,他引:4
Data on 1248 cases of stomaches radically operated on for cancer at the surgical departments of the Moscow Regional Research Clinical Institute in 1971 to 2000 were used to study a number of problems associated with cancer of the upper stomach, by regarding the present-day role of radiation diagnosis as of paramount importance. The following radiation diagnostic techniques were assessed. Among them there were traditional X-ray studies (in each case), the new radiation diagnostic techniques: ultrasound study and computed tomography (CT) (750 studies), magnetic resonance imaging (MRI) (120 studies). The potentialities of radiation diagnosis and endoscopy performed in all cases are compared. A specially developed procedure for exploring endophytic forms of gastric cancer was employed in the morphological studies of the material. The incidence of cancer of the upper stomach and its association with the esophagus are presented; some aspects of the morphogenesis of cancer of this site are discussed. The relationship of its clinical symptoms and its radiation image has been studied. In the authors' opinion, the past two decades' rise in the incidence of proximal gastric cancer is one of the main problems in diagnosing gastric cancer that continues holding its stand in the general structure of cancer morbidity. The tendency for diffuse and mixed forms to increase in the morphogenesis of gastric cancer provides evidence that radiation techniques should be actively used in its diagnosis. It is necessary to apply classical double-contrasting X-ray study and endoscopy on equal grounds as basic diagnostic methods at early stages. Only their concord use may change the poor situation associated with the diagnosis of cancer at this site. CT and MRI as additional techniques may substantially provide more required diagnostic information. This is first and foremost associated with difficulties in gastric endoscopic study when esophageal cancer is apparently proved. 相似文献

Some children with bilateral cleft lips do not grow a long enough nose and require surgical lengthening of the nose. We review our 12-year experience with a one-stage slide operation to achieve this. Seven males and 5 females had this operation at ages 7 through 13 years, and we have followed them from 6 months to 12 years. The results, and the subsequent growth effects are described. In general, good long-term improvement has been achieved and the external scars have not proved to be a major drawback. Subsequent procedures upon the columella, alae, and upper lip are often required to establish an unobtrusive nasal appearance. 相似文献

Traditional X-ray and endoscopy methods of research have limited abilities in expotion of the all parameters of the esophagus tumor. It becomes clear, that this method is not satisfactory enough. It's clear that without information about all parameters of cancer infiltration surgical and combined (operation + radiotherapy) treatment do not give desired result. With an objective to study this matter, 290 X-ray pictures of 150 patients with cancer of the middle and lower mediastinum sections of esophagus and were getting treatment, were studied and analyzed. It was identified, that correspondingly to the filling defect with the esophagus cancer on the phone of the light stripe of mediastinum the external contours give the full picture of the tumor infiltration. Rehabilitation of esophagus function during the process of X-ray therapy in parallel with the deduction of the shadow of the tumor infiltration the phone of mediastinum, give a floor to our suspecion, that abovementioned shadow is the anatomic substrate of the esophagus tumor. It is very important to reveal all tumor's parameters in diagnostics and radiation therapy of the esophagus cancer. 相似文献

One-stage reconstruction of the central and lower abdominal wall with vascularized tissue has been well described. A few cases of one-stage reconstruction of the upper abdomen also are reported. We attempted this procedure in six of seven patients who had large abdominal wall defects that reached the xiphoid process. In three patients, the intraabdominal parts of the procedures went well and the reconstructive goals were accomplished. In three other patients, prolonged and difficult intraabdominal operations resulted in considerable intestinal dilatation that compromised the reconstruction. We therefore recommend being prepared to abort a planned immediate abdominal wall reconstruction following a difficult intraabdominal operation. The abdomen should be temporarily closed with skin flaps, skin grafts, or absorbable mesh, and definitive reconstruction of the fascia should be done at a later operation. 相似文献

Pancreatic pseudocyst, a common complication of acute or chronic pancreatitis, in rare instances may also extend to the mediastinum. A case of 67-year-old woman presenting with a triad of chest pain, dysphagia, and dyspnea is presented. The patient had an episode of acute alcoholic pancreatitis 1 year before presentation. Chest radiography on admission showed a retrocardiac opacity. Two-dimensional echocardiography revealed an echolucent mass compressing the left atrium. A subsequent upper gastrointestinal series for her dysphagia showed extrinsic compression of the distal esophagus. Finally a definitive diagnosis was made with computed tomography (scan), which revealed a 19 x 12 cm pseudocyst extending from the body of pancreas into the thorax and compressing the esophagus and the cardiac chambers. A mediastinal pseudocyst can cause symptoms due to compression or invasion of surrounding structures. The fluid collection may enlarge slowly and hence the symptoms can be delayed as in our patient. The pseudocyst was successfully treated using endoscopic ultrasound-guided transesophageal drainage. Approximately 50 cases of mediastinal extension of the pancreatic pseudocyst in the world literature are reported. At this time, this is only the second time that successful drainage of a mediastinal pseudocyst using a transesophageal approach under endoscopic ultrasound guidance has been reported. The literature was reviewed for clinical presentation, complications, and available treatment options for mediastinal pancreatic pseudocysts. 相似文献

A shortened esophagus is probably acquired, rather than congenital, in the great majority of cases. The process by which the shortening develops, as described by Allison and his coworkers, begins with esophageal hiatal hernia, followed by esophagitis caused by the irritation of acids from the stomach, then recurrent ulceration and healing which forms scar tissue which little by little shortens the esophagus. Obesity and relaxation of the supporting musculotendinous structures which accompany advancing years probably are contributory factors in production of esophageal hiatal hernia. Fifteen of a series of 18 patients noted the onset of symptoms on or after the age of 45. Roentgen examination of the esophagus and stomach is indispensable in establishing a diagnosis of acquired short esophagus. Esophagoscopic examination is even more important. In some cases endoscopic differentiation between acute inflammation and carcinoma is difficult. In such circumstances examination of a biopsy specimen taken from the gastric mucosa immediately distal to the area of inflammation or stricture may be helpful. Results in eight patients with advanced esophageal shortening and stricture who were treated conservatively indicate that this should be tried before surgical treatment is considered. For patients with esophageal hiatal hernia accompanied by shortening of the esophagus that is just beginning to produce symptoms, early repair is indicated, since the condition is progressive and the surgical problem is much simpler in the early stages. 相似文献

Background
Leiomyomas of esophagus, although rare, are the most frequent benign tumors of esophagus. Aim of this study is the presentation of 7 patients with esophageal leiomyomas who underwent surgical treatment during a 9-year period.Methods
Epidemiological data (sex, age), the presenting symptoms, diagnostic examinations, tumor location, histopathological findings and the safety and efficacy of surgical resection are analyzed and assessed.Results
5 men and 2 women with mean age of 56.9 years were operated. In 3 cases the tumor was located at the lower esophagus, while in the other 4 cases, the leiomyoma was found at the median third of esophagus. 4 patients had severe symptoms related to the leiomyoma, such as dysphagia and epigastric pain. All patients underwent a right postolateral thoracotomy with enucleation of the lesion. None of them received resection of part of the esophagus. The mean diameter of the resected tumors was 4.3 cm. The dimensions of leiomyomas were immediately associated with the symptoms. In no case was detected malignancy or recurrence. All patients were relieved from their symptoms, while postoperative morbidity and mortality did not occur.Conclusions
Esophageal leiomyoma is a benign tumor, which causes symptoms only if its size becomes large. Surgical enucleation is considered to be safe and effective, without complications. 相似文献17.
A study was undertaken to demonstrate the safety, efficacy and value of esophageal balloon cytology in the diagnosis of esophageal lesions and as a tool in screening a high-risk patient population. The sampling was performed 110 times on 96 patients, 11 with known obstructive carcinoma of the esophagus and 85 thought to be at risk for esophageal cancer: 74 with treated or untreated cancer of the head and neck area and 11 with dysphagia or other findings requiring clarification. The method was well tolerated by the patients, and the cytologic smears were of excellent quality. Malignant or suspicious cells were found in smears from 7 to 11 patients with documented esophageal cancer and in 7 of 85 patients believed to be at risk. In the latter group there were three unsuspected recurrent cancers of the oropharyngeal region and one unsuspected carcinoma in situ of the esophagus. There were no false-suspicious or false-positive results. This noninvasive technique of esophageal cytology obviously deserves additional trials as an adjunct in the diagnosis of carcinoma of the head and neck and upper gastrointestinal tract, especially in high-risk patients. 相似文献

Recent advances in pediatric surgery have been made in several fields. Hydrocephalus is again being treated by draining the cerebrospinal fluid into either the ureter, the mastoid antrum or the peritoneal cavity. Funnel chest should be corrected surgically. Congenital atresia of the esophagus is best treated by a one-stage operative repair. Patent ductus should be closed. Operations are available for cyanotic children. Intussusception is again being treated by barium enema in selected cases. Megacolon can be benefited by surgical procedures, which now are directed at the distal spastic segment rather than the proximal dilated segment. 相似文献
