In order to give an overview of recent advances in general surgery, it is necessary to define: (i) what is general surgery; (ii) what is recent; and (iii) what constitutes an advance. General surgery appears to have entered an era of conservatism. This is particularly evident in the surgery of breast cancer, peptic ulceration, varicose veins, liver trauma, portal hypertension, upper gastrointestinal bleeding, and hiatal hernia. Controlled clinical trials in surgery have become popular. The following are considered to be advances: parenteral nutrition, suction drainage, control of Gram-negative sepsis, bypass surgery for pathological obesity, and a discriminatory approach to transplant surgery.

Members of a state society of gastroenterologist collected information about their pattern of practice. Twenty-two of the 41 members voluntarily kept a list of 25 sequential new patients seen during the spring of 1973. Five hundred and fory-nine diagnoses were accumulated; 369 (67%) of these diagnoses were gastroenterological. The five most common gastroenterological diagnoses were: functional disorder, duodenal ulcer, hiatus hernia, biliary tract disease, and esophagitis. The five most common over-all diagnostic areas were: functional disorder, cardiovascular disease, "other" nongastroenterological diagnoses (including obesity), duodenal ulcer, and endocrine malfunction. Geographically dispersed gastroenterologists in Virginia make more than one-half of their primary diagnoses in the area of their subspecialty interest. The primary gastroenterological problems seen are "upper gut" lesions and biliary tract disease. These observations may be of value in planning education, training, or research activities, especially if verified by a broader sample of gastroenterological practitioners.

To determine the normal morphologic evolution of the diaphragm with aging and to correlate age-related changes with other indicators of physical condition--such as skeletal muscle status, obesity, presence of pulmonary emphysema, and presence of esophageal hiatus hernia--a systematic morphometric and morphologic evaluation of computed tomographic studies of 120 patients from the 3d to 8th decades of life was undertaken. Diaphragm muscle thickness did not change significantly with increasing age. Diaphragmatic defects and pseudotumors, nonexistent in the 3d and 4th decades, increased in number and severity to affect 56% of the patients in the 7th and 8th decades. Neither the status of the skeletal muscle nor the presence of obesity correlated with age or with the presence of diaphragmatic defects. Eighty-four percent of the patients with emphysematous changes demonstrated diaphragmatic defects; thus, a strong association with emphysema was observed. If emphysematous patients are excluded, defects were more common in women. The esophageal hiatus width was found to increase with age.

The combined Collis-Nissen operation has been performed in 353 patients. Forty-five percent had reflux esophagitis without stricture; 20%, peptic stricture; 72%, a sliding hiatal hernia; 17%, a paraesophageal hernia; 21%, previous antireflux operation; 15%, esophageal spasm; 8%, scleroderma; and 32%, marked obesity. There were 4 postoperative deaths (mortality rate, 1.1%). Complications occurred in 28 patients (8%) and included wound infection (2.2%), esophageal or gastroplasty tube leak (1.7%), bleeding (1.1%), splenic injury, gastric atony, and crural repair dehiscence (each less than 1%). Follow-up includes personal interview, esophageal manometry, and standard acid reflux testing. The average length of follow-up for 261 patients (74%) followed at least 12 months is 43.8 months. Fifty-eight percent have been followed at least 36 months; 41%, 48 months; and 29%, 60 months or longer. Subjectively, in these 261 patients, reflux has been eliminated in 75%, is mild in 11%, is moderate in 9%, and is severe in 5%. Eight percent have postthoracotomy pain; 3%, early satiety ("bloats"); and 1%, postvagotomy diarrhea. Seventeen percent require either periodic or regular esophageal dilations for dysphagia. Objectively, intraesophageal pH studies show good reflux control in 91% and poor reflux control in 9%. Twenty-six patients (10%) have required reoperation for recurrent reflux or dysphagia. These results substantiate satisfactory reflux control using the Collis-Nissen operation in patients at risk for recurrence after standard repairs, but also emphasize that, like other antireflux procedures, the Collis-Nissen operation is not without some degree of postoperative adverse symptoms.

A silicone collar containing circumferential tape was tied around the cardio-esophageal junction in eight patients with symptomatic, refractory reflux, who were not good candidates for a standard antireflux procedure. A fine polypropylene tie or clip secured the knot. In two patients with large hiatal defects, the crura were approximated loosely. Mean operating time, including one cholecystectomy and one ventral hernia repair, was 51 minutes. Patients who underwent this simple operation had a combination of hypertension, heart disease, obesity and old age, and two had undergone horizontal gastroplasty previously for morbid obesity. The reflux was associated with hiatal hernia in seven of the eight patients. Preoperative studies included barium swallow roentgenography in all eight patients, and endoscopy, manometry and Bernstein test in six. All the studies were repeated postoperatively. Follow-up ranged from 17 to 48 months (mean 37.8 +/- 10.6 months). Postoperatively, there was a significant (p less than 0.01) improvement in symptoms, endoscopic findings and lower esophageal sphincter pressures. No prosthesis has migrated yet.

Exophiala jeanselmei was isolated from three esophageal cultures over an 11-month period at Lutheran General Hospital. We believe this provides evidence for a new site of isolation, since previous reports of the organism's incidence were confined to skin and lung. Case 1 is an eight-year-old female with a three-year history of gagging and vomiting. Esophagoscopy revealed a mass biopsied as vegetable material. Case 2 is a 66-year-old retired male with a history of obesity, diabetes and spinal stenosis. Following back surgery, the patient developed odynophagia. Esophageal biopsies showed ulceration and bacterial colonies with no evidence of fungus. Case 3 is a 62-year-old male gardener who is also a nail biter. Esophagoscopy revealed a gastro-esophageal stricture with reflux and evidence of a hiatus hernia. Material biopsied was consistent with Barrett's esophagus and evidence of fungi was seen. The esophageal mass of case 1 and the esophageal brushings of case 2 and 3 grew E. jeanselmei. Aspiration, reflux, and mechanical disruption of the esophageal mucosa are possible predisposing factors in colonization of esophageal lesions by this ubiquitous, normally low virulence organism.

With westernization of diet and lifestyle among South African Blacks, particularly urban dwellers, hitherto unknown gastro-intestinal diseases are becoming evident. Previously unreported is hiatus hernia, now a definite disease entity, although still very uncommon. At Baragwanath Hospital, Johannesburg, over 17 months in 1977-1978, 46 patients with hiatus hernia were detected from barium meal examinations on 1392 persons, i.e. 3,3%, or 0,07% of total hospital admissions of adults. The disease affected mainly middle-aged and elderly women. Prevalences of obesity, comparative physical inactivity and hypertension appeared commoner than in the general urban adult population. Just as appendicitis is a marker of westernization in young urban Blacks, hiatus hernia may be regarded as a marker in the middle-aged and elderly.

The case of a 23 years old woman, affected by the Cohen syndrome, who underwent general anesthesia for extensive dental surgery, is reported. The Cohen syndrome is an autosomal recessive syndrome that causes mental retardation, obesity, short stature as well as oral, ocular, and limb anomalies. The problems the anesthesiologist could deal with include the capacity of the patient to cooperate; difficult intubation because of maxillary hypoplasia, micrognathia, narrow and high-arched palate, and prominent maxillary central incisors; generalized muscular hypotonia; moderate leukopenia, that could theoretically increase the risk of infection: and, finally, possible associated mitral valve prolapse or hiatus hernia. In the case reported the presence of mitral valve prolapse or hiatus hernia was ruled out echographically. The patient was premedicated with diazepam and atropine i.m.; general anesthesia was carried out by propofol-fentanyl association and myorelaxation was obtained with atracurium. Nasotracheal intubation was performed easily in spite of oral anomalies so that the usefulness of thyromental distance, which was 7 cm long, as a clinical test to evaluate a potentially difficult intubation was confirmed. Noteworthy, the thyromental distance was the only test which was suitable for the uncooperative patient. At the end of surgery muscular tone recovered promptly and the endotracheal tube could be regularly removed. No complication was registered postoperatively.

Eleven patients underwent left transthoracic reoperation for recurrence of hiatus hernia after previous surgical treatment. A left thoracic approach was chosen because of three cases of major obesity, three patients with multiple previous laparotomies, three recurrences of para-esophageal hernia, three associated dyskinetic disorders of lower esophagus. Ten patients underwent a Belsey Mark IV procedure with three myotomies of lower esophagus and one pyloroplasty. One patient underwent a Collis-Belsey procedure. Operative mortality was zero. Every patient had been followed up with a mean of 31 months. Ten patients have a good result. One patient had a massive recurrence of gastroesophageal reflux after Belsey Mark IV which led to a duodenal diversion 18 months later. Although the abdominal approach allows easier dissection of lower esophagus and complementary procedures to the lower esophagus. Results are as good as those of the abdominal approach.

Four hundred and thirty patients with grade 2 or 3 esophagitis were treated after 2/1 randomization for 8 weeks with omeprazole 20 mg (n = 294) or ranitidine 150 mg bid (n = 136). Apart from treatment, 8 epidemiological factors (gender, age, occupation, obesity, smoking, alcohol, NSAID, and coffee or tea consumption), 5 clinical factors (day/night pain distribution, burning score, severity of regurgitation and of dysphagia, number of painful episodes requiring prescription of an antisecretory agent during the previous year, and onset of symptoms before age 30) and 3 endoscopic factors (grade and upward extension of esophagitis, and existence of hiatal hernia > or = 5 cm) were analysed. The influence of these factors on healing at 8 weeks and on changes in symptoms was evaluated by multivariate analysis. 92.1% of patients enrolled were analyzed. In comparison with ranitidine, omeprazole increased the percentage of healed patients (93% v. 67.5%, p < 0.001) and the rapidity of disappearance of symptoms (5 days v. 7 days, p < 0.001). Independent good prognostic factors associated with healing rate were treatment with omeprazole (p < 0.001) and grade 2 esophagitis (p < 0.001) while those associated with the disappearance of symptoms were a low burning score (p = 0.001), advanced age (p = 0.004), treatment with omeprazole (p = 0.005), the absence of any occupation (p = 0.01) and male gender (p = 0.017). The results of this study show that, apart from treatment, endoscopic factors are predictive of the healing of reflux esophagitis treated by antisecretory agents while clinical factors are more important with regard to the disappearance of symptoms.
