The complication rate in jejunoileal bypass for morbid obesity is unacceptably high. Gastric bypass is technically difficult. In our series, 115 patients have undergone gastric partitioning for morbid obesity. The operation consists of stapling across the stomach below the gastroesophageal junction, leaving a gastric food reservoir of 50--60 cc. A 1 cm opening is left in the central portion of the staple line, allowing slow emptying into the distal stomach. The result is a reduced eating capacity and frequency which produce loss in weight. Three-quarters of the patients are women, and the age range is 17--62 years. Preoperative weights averaged 147 kg. Mean operative time was 48 minutes, and postoperative stay was 6.2 days. All patients were extensively evaluated preoperatively with upper GI series, cholecystogram, a number of blood chemistry tests, and endocrinologic and psychiatric consultations. All patients underwent a preoperative Minnesota Multiphasic Personality Inventory test. Cholecystectomy for cholelithiasis was performed on 18% of the patients at the time of operation. Of the seven patients operated on more than one year ago, five have lost an average of 31.6% of their preoperative weight. Of the 12 operated on less than one year but more than six months ago, eight have lost an average of 21% of their initial weight. The early failure rate of 33% has been reduced to 15% at present. One death occurred from pulmonary embolus 10 days following discharge, giving a mortality rate of .08%. The complication rate is 10%, comprising two pulmonary emboli, two psychoses, one wound dehiscence, one wound hernia, and ten wound infections, six of which were minor. There have been no complications of ulcer disease, reflux esophagitis, liver disease, renal disease, or metabolic disorders. Gastric partitioning is a safe, fast effective alternative for the surgical treatment of morbid obesity.

Findings in this study correlated a low circulating gastrin level with an incompetent lower esophageal sphincter mechanism and abnormal reflux. Such reflux, in amounts causing esophagitis distally, was treated surgically by a mechanically simple method of fundoplication. The success of this reefing method of fundoplication was explained by using physiologically active sling fibers of the gastric fundus to augment the lower esophageal sphincter. Available gastrin was used more effectively in this manner. The high incidence of associated foregut diseases suggested an embryologic factor in the development of gastroesophageal reflux. The dilated hiatus and its attendant hernia had no apparent relationship to the development of reflux esophagitis. The term symptomatic sliding hiatal hernia, therefore, seemed to be a diagnostic and therapeutic misnomer.

Surgical intervention is usually indicated in reflux esophagitis when medical therapy fails to control symptoms. Since most patients with peptic esophagitis also have a sliding hiatal hernia, early procedures focused on hernia repair. Weakness of the lower esophageal sphincter is now known to be the pathogenetic mechanism, and Belsey, Nissen, and Hill have developed operations to restore sphincteric function. The Hill repair is used most often because of its low incidence of side effects, but the other procedures are recommended in specific situations. Stricture, the most common complication of reflux esophagitis, presents a special problem in treatment because interference with swallowing is added to the characteristic symptoms of reflux. Because of its high long-term success rate, the combined Thal-Nissen procedure is preferred to forceful dilation plus an antireflux operation.

The incidence of anemia in 259 patients with a diaphragmatic hernia large enough to be seen on a routine chest roentgenogram was compared with that in 259 age- and sex-matched controls. Eighteen patients with diaphragmatic hernia were anemic, compared to one control subject (P less than 0.001). In thirteen patients with diaphragmatic hernia and in one control the anemia was proven to be caused by iron deficiency. The findings provide additional evidence that a large diaphragmatic hernia can cause anemia secondary to chronic gastrointestinal blood loss, which is usually not the result of reflux esophagitis.

The authors report a case of Zenker's giant hypopharyngeal diverticulum in an elderly patient who underwent surgery due to the severity of symptoms. This diverticulum, which is both juxtasphincteric and epiphrenal, has a pulsion pathogenesis: the presence of a hernia on the esophageal side (jato?), with which Zenker's diverticulum is frequently associated and which is often followed by reflux esophagitis, is enough to cause motor asynchronism of the crico-pharyngeal muscle which, in the presence of hypertonic conditions during deglutition, leads to the formation of a high-pressure pouch which is then responsible for the formation of the diverticulum itself. It is therefore important to check whether an associated esophageal pathology exists once Zenker's diverticulum has been diagnosed: X-ray examinations of the upper digestive tract are undoubtedly capable of identifying the presence of the diverticulum as well as other pathological associations. In the present case it was not possible to perform a sufficiently exhaustive X-ray examination in order to exclude associated esophageal pathologies. Endoscopy may be superfluous and contraindicated in cases of large diverticular pouches. Symptoms vary depending on the size of the diverticulum. A feeling of dysphagia may precede the appearance of the diverticulum, even by several years, before the onset of symptoms related to the ingestion of food: initially the patient may experience the sensation of a foreign body while eating due to the accumulation of ingested food in the diverticulum; this is followed by halitosis, sialorrhea, noisy deglutition, regurgitation of undigested food especially during sleep, and frequently bronchopulmonary symptoms "ab ingestis".(ABSTRACT TRUNCATED AT 250 WORDS)

The author studied the condition of the esophagogastric junction in 376 patients with gastric and duodenal ulcer before and in the late-term periods after selective proximal vagotomy and distal resection of the stomach performed in combination with antireflux interventions on the cardia (fundoesophagorrhaphy, crurorrhaphy+fundoesophagophrenorrhaphy, fundoplication) or without such interventions. It is shown that reliable correction of the obturator mechanism of the cardia in selective proximal vagotomy may be achieved only by fundoplication. In gastric resection fundoplication is advisable in marked reflux esophagitis, distention of the hiatus esophageus of third degree, hernia of the hiatus esophageus, and cardiac ulcer. In all other patients with distal resection of the stomach crurorrhaphy+fundoesophagophrenorrhaphy is justified as a preventive measure.

This study was undertaken to clarify the incidence of hiatus hernia and the functional changes in the cardia of post-gastrectomy patients. One hundred and four post-gastrectomy patients and 399 non-gastrectomy patients were selected for endoscopic study, and the diagnosis of hiatus hernia was made by observing the shape of the cardia inside the stomach. A manometric study was also done on 12 patients with gastric carcinoma and 14 patients with gallstones. Hiatus hernia was observed in 37.5 per cent of the post-gastrectomy patients, this incidence being significantly higher than the 19.3 per cent of the non-gastrectomy patients (p less than 0.01). In the latter group alone the incidence of hernia steadily increased with advancing age. In the post-gastrectomy patients, reflux esophagitis and heartburn were observed in 20.2 per cent and 27.9 per cent, respectively. These incidences tended to be higher in the patients with hernia but there were no significant differences. The manometric study revealed that lower esophageal sphincter pressure was significantly decreased after gastrectomy, but not after cholecystectomy.

A prospective study of the incidence of hiatus hernia and/or reflux oesophagitis was carried out in 670 patients referred for routine upper alimentary endoscopy. Hiatus hernia was found in 16.6% and reflux oesophagitis in 15.1% of the patients. Forty-two per cent of the patients with hernia did not have oesophagitis, whereas 63% of the patients with reflux oesophagitis had hernia. In patients without reflux oesophagitis the incidence of hiatus hernia was 8%. Reflux oesophagitis was significantly (p less than 0.001) related to hiatus hernia. The severity of the oesophagitis was significantly (p less than 0.05) related to the presence and the size of hernia, and severe oesophagitis without hernia was significantly (p less than 0.01) related to chronic alcoholism. The results suggest that a sliding hiatus hernia may play a role in the development of reflux oesophagitis.

Between 1960 and 1980, 53 patients with massive incarcerated hiatal hernia were treated surgically. In 24 of the 53 patients, there was an associated organoaxial volvulus. The following symptoms and signs, which are almost peculiar to massive, incarcerated hernias, were observed: postprandial precordial distress in 43 patients, upper gastrointestinal bleeding (manifest or occult) in 24 patients, severe dyspnea in 13 patients, and complete obstruction associated with organoaxial volvulus in 4. In only 1 of the 53 patients was the hernia of the true paraesophageal type with the esophagogastric junction remaining in its normal, intraabdominal location. The remainder were all believed to be advanced stages of an ordinary sliding hiatal hernia. Operative treatment consisted of gastroplasty and partial fundoplication in 36 patients, standard Belsey repair in 14, and transabdominal Nissen repair in 3. Gastroplasty and partial fundoplication were used much more frequently during the 1970s, when it was realized that there is a significant incidence of chronic peptic esophagitis and shortening in these patients. Postoperative complications were few in spite of the advanced age of many of the patients. There was one operative death. Only 1 patient was lost to follow-up, and of the 51 patients remaining for analysis, follow-up has extended from 1 to 16 years, with a mean of 6.2 years. No patient has developed recurrent precordial pain, evidence of upper gastrointestinal bleeding, iron deficiency anemia, or severe dyspnea. Seven patients have residual dysphagia; this condition is minimal in 5, and is significant in 2 who require interval esophageal dilation. Nine patients have symptomatic reflux, which is minimal in 5 patients, moderate in 2 patients, and severe in 2 others who were subsequently reoperated on. Contrary to popular concept, our observations indicate that almost all of these patients represent advanced degrees of sliding hiatal hernia with intrathoracic displacement of the esophagogastric junction. This implies a need for an adequate antireflux reconstruction in all patients undergoing operation, as well as an awareness that unanticipated cicatricial changes may be present in the distal esophagus and may prejudice the success of some of the standard hiatal repairs.

At the University of Minnesota, under the supervision of one staff surgeon, both the jejunoileal bypass (JIB) and gastric bypass (GIB) operations have been done for weight reduction in morbidly obese individuals. Over the past 11 years, end-to-end (40 to 4 cm) JIB performed for 727 patients. In addition, antecolic GIB was performed for 364 patients over the past 6 years. This report is based primarily on a comparison of 205 JIB and 106 GIB patients with surgery between July 1975 and July 1979. Adequate weight loss was seen in 75% of each group. The percentage of excess body weight loss was similar for the first year (65% for JIB and 62% for GIB); however, the JIB patients started at 214% of ideal weight and GIB patients at 197% of ideal weight. The operative mortality rate for either operation was well below 1%, and the immediate operative morbidity rate was low and only rarely delayed discharge from the hospital. The long-term complications for JIB were 37.7% arthralgia or arthritis, 7.1% oxalate urolithiasis, 5.6 incisional hernia, and 1.4% liver failure; complications of GIB were 10.2% nausea and/or vomiting, 1.9% reflux esophagitis, and 2.8% anastomotic problems. At 1 year, plasma cholesterol reductions for JIB patients averaged 42% (P less than 0.001), whereas for the GIB patients it ws only 14% (P less than 0.001). At 1 year after operation, 49% of 88 JIB patients showed progression of liver disease on sequential biopsies, with 31% unchanged and 20% improved. In 43 GIB patients, the biopsies showed improvement in 58%, an unchanged status in 30%, and worsening in 12%. The levels of serum glutamic oxaloacetic transaminase and alkaline phosphatase increased after JIB and eventually returned to normal, while GIB patients had only minor fluctuations of liver function tests. Comparable therapeutic weight results occurred with JIB and GIB; however, the GIB was associated with far fewer serious long-term complications and the JIB with a far greater cholesterol lowering. A percentage of the GIB patients showed progression of liver disease at 1 year after bypass.
