The authors report on a series of 14 cases (10 men and 4 women) of epiphrenic diverticula treated surgically over a period of 14 years. Size was variable and the neck was narrow in 7 cases, wide in 5, and very wide in 2. Four patients presented with a double diverticulum. The diverticula are normally found on the right side (9 cases), and underlying dyskinesia is always present, often accompanied by major or minor cardiospasm (11 cases) or reflux from sliding hiatal hernia (3 cases). No manometric exploration was carried out in this series. Management was based on physiopathological considerations - 6 diverticulectomies with 5 myotomies, 6 myotomies with no diverticulectomy. The approach was left thoracic in 7 cases and abdominal in the others. The mortality rate was zero, and functional results are good. They are all the better in that the diverticulectomy, the myotomy and the repair of the gastroesophageal reflux have now been performed.

Computed tomography (CT) of the chest and abdomen has proved to be helpful in the preoperative staging of both esophageal and gastric carcinoma. The gastroesophageal junction however, is a difficult area to evaluate as variations in normal anatomy may mimic pathological processes. Pseudomasses at the gastroesophageal junction can be confused with neoplasm. The CT appearance of the GE junction was evaluated in 150 normal patients. CT scans were also performed on 15 patients with carcinoma involving the GE junction. Twenty cases of benign diseases of the GE junction were also studied by CT. Anatomy--The normal anatomy of the gastroesophageal junction will be illustrated with both line diagrams and CT images. The hepatogastric ligament and the caudate lobe of the liver will be demonstrated and their use in locating the GE junction will be shown. Technique--A short segment describing the appropriate technique for CT of the gastroesophageal junction will follow. The use of oral and intravenous contrast will be discussed. The need for distension of the stomach with effervescent agents and oral contrast as well as the use of decubitus and prone positioning will be emphasized when a mass-like density is seen at the GE junction. Examples will be provided. A pseudomass at the GE junction on a supine CT will be shown that disappears with distension and decubitus scanning. This will be used to lead into the next section on neoplasm in which the first example will have an identical appearance on supine CT images. Neoplasm--The relative incidence of gastric adenocarcinoma and esophageal squamous cell carcinoma at the GE junction will be briefly reviewed. The similar CT appearance of the neoplasms will be described and liberally illustrated. Metastatic involvement of lymph nodes adjacent to the GE junction will also be shown. The staging classification for CT evaluation of GE neoplasms will be reviewed. The utility of preoperative staging of esophageal and gastric neoplasms will be briefly reviewed and applied to the GE junction. Our series of patients with cancer of the GE junction will be discussed. The importance of the CT detection of criteria of inoperability will be demonstrated with examples of metastatic involvement of the liver and lymph nodes as well as direct invasion of adjacent organs. Benign Disease--Examples of benign stricture, hiatal hernia, and achalasia will be illustrated. Our cases where CT scans helped rule out a malignant process that had been suggested on barium studies will be reviewed. Summary and Conclusions--Important points of technique, normal anatomy, benign and malignant disease will be briefly reviewed.

We reviewed the radiographic findings in thirty patients with columnar-lined (Barrett's) esophageal mucosa. Gastroesophageal reflux was observed in 90%, hiatal hernia in 83%, stricture in 80% and esophageal ulceration in 33%. Superficial nodular mucosal changes were detected on 50% of the air contrast esophagrams. Prominence of this pattern may be associated with dysplastic or early malignant change. In addition, four conditions associated with secondary lower esophageal sphincter incompetence were identified in our patient group. These were scleroderma, previous myotomy for achalasia, previous gastric surgery and long-term indwelling nasogastric tubes.

Since 1979 our policy for management of esophageal perforation has included correction of underlying esophageal disorder as part of the initial treatment in selected cases. A series of 23 patients is presented, of whom 3 were managed conservatively and 20 surgically. The overall mortality rate was 8.7%. Concomitant operation of underlying esophageal disease and perforation was done in eight cases within 12 hours of the perforation. These operations included emergency resection and esophagogastrostomy in five patients (4 with stenosis and 1 with cancer). A Heller myotomy was done in addition to suture repair in two patients with achalasia, and a Belsey Mark IV hernia repair was added to the esophageal suture closure in a patient with gastroesophageal reflux and hiatal hernia. A postoperative fistula healed spontaneously in one of the eight patients, and the early postoperative course was uncomplicated in the other seven. Simultaneous correction of underlying esophageal disease in patients with iatrogenic perforation of the esophagus seems to be safe when perforation is diagnosed at an early stage. Such a radical approach is clearly beneficial.

This study was intended to specify the most appropriate procedure of myotomy and fundoplication in the modified Belsey Mark IV operation toward the esophageal achalasia to prevent post-operative refluxes. Adult mongrel dogs were prepared under surgical operation of, short myotomy, short fundoplication, long myotomy, long fundoplication, long myotomy, long fundoplication of artificial hiatus hernia type control. After the well recovery, they were examined on their simultaneous evaluation of pH and inner pressure at three points, i.e. the esophagus, the high pressure zone (HPZ), and the stomach. At the same time, withdrawal pH curves, etc. were also determined. The discussion resulted that the group of short myotomy, short fundoplication and the group of artificial hiatus hernia type long myotomy, long fundoplication were significantly superior to the group of long myotomy, long fundoplication. As the consequence of the experiment, firstly, the possibility that the surgical operation of long myotomy, long fundoplication causes hypertension of the intrathoracic esophagus, which resulted in the dysfunction of the anti-reflux mechanism of the valves was suggested. Secondly, it has been revealed that this dysfunction did not occur in the surgical operations on the length of HPZ. And thirdly, when the conventional Mark IV operation, which buries all the portions of the fundoplication under the diaphragm, causes hypertension to the intrathoracic esophagus, the surgical operation of artificial hiatus hernia type shall be applied to herniate the upper portion of the fundoplication to the thoracic cavity.

Primary motor disorders of the esophagus can be managed surgically with excellent results. Between the years 1972 and 1983, 40 patients were managed by us. The patients ranged in age from 14 to 79 years (mean 36.3 years). Thirty-six patients were managed primarily by the authors and 4 patients secondarily. The distribution of the hypodynamic states were achalasia in 29 patients, vigorous achalasia in 5 patients, and diffuse spasm in 1 patient, whereas the hyperdynamic states were squeeze syndrome in 2 patients, super-squeeze syndrome in 1 patient, and hypertensive lower esophageal sphincter in 2 patients. Of the 36 patients in hypodynamic states, 27 had a modified Heller myotomy and reconstruction of the gastroesophageal junction with a Belsey fundoplication and 9 had only a modified Heller myotomy. There was only one patient with reflux esophagitis. It occurred after myotomy and Belsey fundoplication for a hypertensive lower esophageal sphincter and hiatus hernia. Four patients were managed secondarily for complicated recurrent problems, one with a Belsey fundoplication and three with a jejunal interposition graft. We recommend myotomy, with or without a Belsey fundoplication, for management of primary motor disorders and avoidance of total Nissen fundoplication and a lengthening Collis gastroplasty.

This study attempted to define the esophageal motor disturbances and pathogenesis of symptoms in patients with lower esophageal diverticulum. Sixty-five patients were investigated by manometry in addition to roentgenography and endoscopy. Fifty had manometric evidence of abnormal motility, most often diffuse spasm or achalasia. Of the 15 patients with normal esophageal motility, 13 had hiatal hernia, and five of these had a high grade distal esophageal stricture. Pressures in the lower esophagus and lower esophageal sphincter in patients with lower esophageal diverticulum and motor disturbance were the same as for those in matched patients with motor disturbances but no diverticulum. Dysphagia, chest pain and regurgitation were common presenting symptoms. Of 46 patients with dysphagia, only ten had mechanical obstruction to explain this symptom. Of 32 patients with chest pain, only two had ulceration in the diverticulum as a possible cause of pain. We conclude that the development of lower esophageal diverticulum and its symptoms are associated with a motor disturbance of the esophagus in the majority of patients and with an organic obstruction in the minority of patients. The diverticulum itself is usually not the sole cause of the esophageal symptoms, although diverticula can produce symptoms in the absence of other definable conditions. When surgical treatment is indicated, the diverticulum should be excised and the underlying motor or mechanical obstruction should be corrected to prevent serious postoperative complications and recurrence of the diverticulum and its symptoms.

There is renewed interest, particularly by head and neck surgeons in the pathophysiology of swallowing. Some of the reasons for this are an increased number of patients in the following categories who have swallowing problems: 1) patients postoperative from procedures in the head and neck, e.g., partial laryngectomy, partial or complete excisions of the tongue, pharynx, or mandible; 2) patients with peptic ulcer, hiatal hernia, esophageal diverticula, and cardiospasm; 3) patients who survive severe central nervous system problems such as stroke, brain tumors, aneurysms, or degenerative disease; and 4) patients who survive serious accidents with severe neck trauma. This paper reviews the pathophysiology of swallowing and the methods of diagnosing and treating dysphagia and its complications.

Out of 90 patients with esophageal achalasia seen during the last decade, we found associated esophageal pathology in 46,6% of the cases. The esophagitis occurred with a frequency of 26,6%, whereas esophageal hiatus hernia was found in 14,4%, benign esophageal stenosis in 5,5%, diverticula in 2,2% and tumors in 2,2%. The role of the different ethiopatogeneic factors is discussed as well as the approach to the above mentioned entities.

A review of 44 patients with 50 esophageal perforations from 1966 through 1980 is presented. The age span was 15 months to 94 years and the male to female ratio was 1 to 1. Each case was studied with regard to presentation, etiology, treatment and complications. Twenty-two cases of esophageal perforation followed instrumentation, including 6 secondary to Mosher bag dilatation for achalasia. Of the remainder, seven patients had spontaneous perforation, five had external trauma, five had intraoperative injury, two had caustic ingestion, and one each had foreign body ingestion, Zollinger-Ellison syndrome and an incarcerated paraesophageal hiatal hernia. Management was nonoperative in 12 patients, primary repair and drainage was performed in 23 patients, and 9 patients underwent drainage and diversion. This series plus 824 patients with esophageal perforation accumulated from a review of the literature emphasizes the importance of the influence of different methods of treatment and time lapse between occurrence and therapy. The type of perforation had no significance on this series. As a result of the experience gained from this series, a treatment protocol is proposed for the management of esophageal perforation.
