Heterogeneity of personality traits in massive obesity and outcome prediction of bariatric surgery.

The search for heterogeneity of personality characteristics amongst the massively obese is extended to a larger sample (n = 215) of both males (n = 83) and females (n = 132). The Minnesota Multiphasic Personality Inventory standard scales serve as the data base for a cluster analysis which has yielded four clusters: cluster 1 (n = 36) where all scales fell well within normal limits; cluster 2 (n = 112) was coded as 3-1 and was also within normal limits; cluster 3 (n = 44) was coded as spike 4; and cluster 4 (n = 23) was coded as 2-1-7-3-8-4. Cluster membership was not related to surgeons' four-year follow-up overall outcome rating. Discriminant function analysis yielded two variables (patient age and MMPI scale 1 T-score) which were significant predictors of subsequent outcome. The results suggest that there is heterogeneity of personality traits among the massively obese and offer encouragement to the search for variables that are even more effective predictors of the outcome of bariatric surgery.

Jejunoileal bypass arthritis.

Although intestinal bypass procedures are no longer performed, important lessons have been learned concerning clinical arthritides resulting from bacterial overgrowth and immune complex deposition. This information is of considerable value in patients who present with the clinical picture of intestinal bypass arthritis on the basis of other bowel abnormalities. Furthermore, the pathogenetic mechanisms involving bacterial overgrowth, release of bacterial antigens, and immune complex deposition may be pertinent to many types of inflammatory arthritis.

Gastrointestinal lymphoma and sarcoma. A case for aggressive search and destroy.

The incidence of sarcomas of the gastrointestinal tract has remained the same, but gastrointestinal lymphomas are gradually contributing a larger percentage of malignant gastrointestinal neoplasms. The authors have examined their more recent experience with these relatively rare lesions. Twenty-eight patients (13 with lymphoma, 15 with sarcoma) have been treated at the Vanderbilt University and the Metropolitan Nashville General Hospital since 1976. There were eight men in the group with lymphoma and six in the group with sarcoma. The average age for patients with lymphoma was 66 years; the average age was 57 years in the patients with sarcoma. Seven patients with lymphoma and eight patients with sarcoma had been treated for 6 months to 3 years for presumed peptic ulcer disease. Eight of these 15 patients were found to have perforated tumors at the time of surgical exploration. Three patients (all in the group with sarcoma) had metastatic liver disease or peritoneal implants at the time of diagnosis. Treatment for most patients included resection of the tumor, followed by chemotherapy or radiation in cases of tumor perforation or metastatic disease. The survival rate for patients with lymphoma has averaged 5.5 years, with a 55% 5-year survival rate. Patients with cleaved cell tumors survived longer than those with other types of lymphoma. In the group with sarcoma, the survival rate has been 3.1 years on the average, with a 21% 5-year survival rate.

Bypass arthritis and the blind intestinal loop.

Arthritis and other inflammatory processes are well established complications of intestinal bypass operations, and recently have been reported after other gastrointestinal procedures. Bacterial overgrowth in blind intestinal loops, actual or functional, appears to be the underlying pathophysiologic mechanism responsible for these systemic inflammatory disorders. In the case we have reported, arthritis was the primary manifestation of blind loop remaining after incomplete reversal of a jejunoileal bypass. Surgical elimination of the blind loop was curative.

Experience with adrenocortical neoplasms in childhood.

The experience with adrenocortical neoplasms in childhood is reviewed. During three decades, ten children with adrenocortical neoplasms were seen at the authors' institution. The literature was reviewed, and 209 patients 16.5 years or younger were found. All ten patients at Vanderbilt University Hospital (VUH) presented with endocrine manifestations of the tumor. Three patients had Cushing's, two patients had virilization, and five patients had features of both. In the literature, virilization, alone or with Cushing's, was the most common mode of presentation. Feminizing tumors were uncommon and nonfunctional tumors rare. The majority of patients were female. Features associated with malignancy included 17-KS levels greater than 40 mg/24 hr, diameter greater than 6 cm, weight greater than 500 g, and histologic evidence of diffuse growth pattern, vascular invasion, and tumor cell necrosis. Although uncommon, adrenocortical neoplasms should be suspected in children with Cushing's, virilization, feminization, or a combination of these. There has been an increased incidence reported in patients with hemihypertrophy, Beckwith-Wiedemann syndrome, hemangiomas, and nevi. Following endocrinologic evaluation, imaging studies should be performed. CT scan appears to be the most useful diagnostic tool. A posterior operative approach is recommended for suspected adenomas. An anterior thoracoabdominal approach is favored for suspected malignancies with uncompromised en bloc resection. There is no evidence that adjuvant therapy provides any additional benefit.

Is ileoproctostomy a reasonable procedure after total abdominal colectomy?

A 17-year study has been made of 63 patients who had a variety of colonic disorders treated by total abdominal colectomy with ileorectal anastomosis in four hospitals affiliated with Vanderbilt University. Forty-three of these patients made an uneventful recovery, but 20 others sustained significant complications, nine of which proved to be fatal (hospital mortality rate, 14%). The study shows (and confirms the work of others) that ileorectal anastomosis after total abdominal colectomy is a reasonable procedure that provides satisfactory results on a long-term basis in a majority of patients when strict criteria in patient selection are followed in its application.

Tumors of the adrenal cortex and Cushing's syndrome.

Fifty-nine patients with Cushing's syndrome, due to adrenocortical tumor, were studied and treated during the period 1953 through 1983 at Vanderbilt University Medical Center. Cushing's syndrome is caused by hypercortisolism that can be due to (1) medicinal use of steroids, (2) excess pituitary secretion of adrenocorticotropin (ACTH) (Cushing's disease), (3) adrenocortical tumor, benign or malignant, and (4) the ectopic ACTH syndrome. Clinical and endocrinologic features of Cushing's syndrome are described, and differential diagnosis of adrenocortical tumor by precise endocrinologic studies is detailed. Computerized axial tomographic (CAT) scan is currently the most accurate imaging modality for preoperative localization of tumors. Preoperative differential diagnosis between adrenocortical adenoma and carcinoma has become fairly accurate. Operative approaches in each category are described. Follow-up from 1 to 30 years has been completed for all patients, except for one who was lost after 7 years. Results of surgical treatment of adrenocortical adenomas are excellent, but the salvage from adrenocortical carcinomas is poor.

The management of gastric ulcers. A current review.

In the past 10 years, 163 patients with documented gastric ulcers were treated at Vanderbilt University and Metropolitan Nashville General Hospitals. One hundred thirty-five were initially managed medically. Medical therapy was successful in 58 patients (43%) in this group. Twenty-eight (17%) patients required surgical treatment initially. An additional 77 patients (57%) became candidates for surgical management when their medical management failed. Of this group, 40 now have been surgically treated and 37 still have symptoms while on medical treatment. Three patients being treated for benign ulcers, two for as long as six years each, were found to have carcinoma of the stomach diagnosed by subsequent endoscopy and biopsy in one and by laparotomy with gastrectomy to include the ulcer in two. We consider subtotal gastrectomy or surgical resection of the antrum, including the ulcer site, to be the preferred surgical treatment for gastric ulcers, and this was done in 50 cases. Vagotomy was done in addition to the antrectomy in 31 of these, and in addition to the subtotal resection in 11. Two patients who had vagotomy and resection subsequently developed a marginal ulcer. One of these who had a subtotal resection and vagotomy healed with medical treatment. The one who had a vagotomy and antrectomy required a second vagotomy for a missed vagus nerve. Gastrointestinal endoscopy in the past 10 years has improved to the point that very few malignant ulcers are missed by endoscopic biopsy. Large ulcers, those that perforate or continue to bleed, and those that fail to heal on medical treatment for a maximum of 2 to 3 months should be submitted to an antrectomy that includes the ulcer. Vagotomy should be added in selected cases.

Surgical management of esophageal achalasia.

Between 1970 and 1983, 46 patients were hospitalized in the Vanderbilt University Medical Center and the Metropolitan Nashville General Hospital for treatment of achalasia. All patients had been symptomatic for at least two years. Efforts were made initially to manage most of these patients (40) with periodic esophageal dilatation. This was successful in only six cases (15%). In four instances (10%), patients had esophageal perforation. Thirty patients have had esophagomyotomy (Heller procedure), and 14 of these had an associated antireflux procedure. Three had proximal gastric vagotomy for associated duodenal ulcer disease. Twenty-seven (90%) have had a good result, three died postoperatively, and two elderly patients had postoperative myocardial infarction. The other patient had sepsis after repair of a perforated esophagus. While periodic esophageal dilatation is necessary in patients who may not tolerate an operative procedure, most patients with achalasia are best treated with Heller esophagomyotomy.

Results of an aggressive surgical approach to gastric carcinoma during a twenty-three-year period.

The early work of Dr. William Longmire with total gastrectomy for gastric carcinoma prompted us to initiate an aggressive surgical approach to gastric carcinoma in 1960: in curative resections radical total gastrectomy with hepaticoceliac-left gastric arterial node dissection was to be performed for tumors involving the entire stomach or upper two thirds and radical 80% to 90% subtotal gastrectomy with similar node dissection for tumors located in the antrum. During a 23-year period 213 patients with confirmed gastric carcinoma were studied. Celiotomy was performed in 192: advanced gastric cancer was found in 185 and seven had early gastric cancer. In only 80 patients could resections for "cure" be done. In 31 patients who underwent total or extended total gastrectomy the operative mortality rate was 9.6%, and life table survival curves show a better survival rate than in 49 patients treated by subtotal gastrectomy, with an operative mortality rate of 16.3%. The study shows the urgent need for diagnosis of early gastric cancer by gastroscopic screening of adults at risk and the meager salvage by radical resection in advanced disease.

Pseudotumor of the lung.

Benign lung tumors in children are rare. An equally uncommon finding is the inflammatory pseudotumor, a lesion that is grossly similar to a tumor and yet cannot be histologically defined as a neoplasm. They have been called xanthomas, histiocytomas, solitary mast cell granulomas, and xanthogranulomas by various authors. There is a tendency to overtreat these lesions as if they were malignant. In previous reports, lobectomy has been the usual treatment for these tumors. If a pseudotumor is suspected at exploratory thoracotomy, a wedge resection and frozen section should be considered. When these benign lesions are easily accessible, they can be enucleated, leaving all of the normal pulmonary tissue intact without compromising cure.

Microbial colonization and hepatic abnormalities in jejunoileal bypass with resection, ileal mucous fistula, and ileocolostomy.

A role for bacterial colonization of the intestines in the pathogenesis of hepatic abnormalities after jejunoileal bypass was sought. Dogs were divided into groups according to the disposition of the bypassed segment; resection (group I), exteriorization as an ileal mucous fistula (group II), and drainage via an ileocolonic anastomosis (group III). Weight loss, abnormalities in liver function, and hepatic steatosis were significantly greater in groups II and III than in group I. Concomitantly, there was a significant increase in the total number of bacterial colony-forming units in groups II and III. Moreover, a greater number of specific anaerobic genera was isolated in group III than in group II. It is concluded that: (1) retention of the bypassed intestinal segment is associated with greater changes in liver function and structure than when the segment is resected; (2) the changes in the liver correlated with bacterial proliferation in the bypassed intestinal segment; and (3) despite a greater number of anaerobic genera in the ileocolostomy than in the mucous fistula, both procedures were associated with hepatic abnormalities.

Coarctation of the abdominal aorta: pathophysiologic and therapeutic considerations.

Coarctation of the aorta is the most frequent cause of hypertension in infants and children. Ninety-eight per cent of coarctations occur in the descending aorta near the ligamentum arteriosus. Five patients are presented with the relatively rare problem of coarctation of the abdominal aorta. The anatomic,pathophysiologic and clinical aspects in these patients cover a range of variants. Clinical and laboratory studies of the genesis of hypertension in coarctation are reviewed in chronologic outline. An experimental model of abdominal coarctation with hypertensive and renin-angiotensin II correlations suggests but does not prove a renal mechanism for the hypertension. The same conclusion must be drawn from study of the clinical cases.
