Gastric outlet obstruction (GOO) secondary to peptic ulcer disease requiring therapeutic intervention remains a common problem. The incidence of Helicobacter pylori infection in this cohort has not been well defined. Pneumatic dilatation (PD) has been proposed as first-line therapy before surgical intervention. If H pylori infection in patients with GOO is infrequent, PD may not offer permanent control without the need for longterm antacid therapy.The purpose of this study was to examine the incidence of H pylori infection and surgical outcomes in patients undergoing resection for GOO. The records of all patients having resection (vagotomy and antrectomy) for benign disease from 1993 to 1998 for GOO at the University of Tennessee affiliated hospitals were reviewed retrospectively. Smoking history, NSAID use, weight loss, previous ulcer treatment, previous treatment for H pylori, and previous attempts at PD were among the factors examined. H pylori infection was documented by Steiner stain from either preoperative biopsy or, in most patients, final surgical specimens. Surgical complications and patient satisfaction were ascertained from inpatient records, postoperative clinical notes, and, where possible, followup telephone surveys.Twenty-four patients underwent surgical resection during the study period. There were 16 men and 8 women, with a mean age of 61 years (range 40 to 87 years). Weight loss was documented in 58% and averaged 27 lb. Five of 24 patients had previous attempts at PD, 3 of whom were H pylori negative. All five had further weight loss after these failed attempts. Of the 24 patients reviewed, only 8 (33%) were H pylori positive. There were no procedure-related deaths. Longterm clinical followup was possible in 16 of 24 patients, and all but one demonstrated dramatic clinical improvement by Visick score.We conclude the following: 1) In this cohort, H pylori infection was present in a minority; 2) previous attempts at PD were unsuccessful, which may be related to the H pylori-negative status of the patients; 3) mortality related to the operation was zero; and 4) patient satisfaction was positive by the Visick scale. Patients with H pylori-negative GOO resulting from peptic ulcer disease should be strongly considered for an early, definitive, acid-reducing surgical procedure.

The effectiveness of technetium 99m-labeled red blood cell scintigraphy in localizing hemorrhage, directing surgical intervention, and screening patients for arteriography was determined in 103 patients. The radionuclide scan result was compared to the bleeding site determined by arteriography, endoscopy, or surgery. Eighty-five patients had a bleeding site identified; 18 patients did not and were excluded. Thirty-one scans were performed in 29 patients for upper gastrointestinal hemorrhage. Five positive scans incorrectly localized an upper gastrointestinal bleeding site, although two scans localized the site, for a scan sensitivity of 8%. Fifty-nine scans were performed in 56 patients with lower gastrointestinal bleeding. Fifteen scans were positive, three incorrectly localizing the hemorrhage. Seventy-four percent of the patients with lower gastrointestinal hemorrhage documented by arteriography, endoscopy, or surgery had negative scans for bleeding. The radionuclide scan sensitivity for lower gastrointestinal bleeding was 23%. Surgery was required in 18 patients for bleeding, 11 of whom had negative scans for bleeding. In seven surgical patients with positive scans, in no instance did the scan direct the surgical intervention. Eighteen patients underwent scintigraphy and arteriography; nearly one half of the patients with negative scans for bleeding had positive localizing arteriograms, although almost one half of the patients with positive scans for bleeding had negative arteriograms. Scintigraphy failed to localize hemorrhage in 85% of the patients. Technetium 99m-labeled red blood cell scintigraphy did not direct surgical intervention, nor did it adequately screen patients for arteriography.

The Organ Injury Scaling Committee of the AAST recently published a consensus classification of splenic, hepatic, and renal injuries (J Trauma, 29:1664, 1989). The hepatic injury scale (HIS), based on parenchymal laceration and intrahepatic hematoma, includes grades 1 to 6, representing the least to most severe injury. This study classifies liver injuries by findings at celiotomy, correlates operative findings with transfusion requirements and method of management of liver injury, and relates preoperative CT to anatomic findings at laparotomy. Thirty-seven patients with blunt liver injury were evaluated by abdominal CT with and without intravenous contrast and then underwent celiotomy. Increasing operative HIS correlated well with increasing severity of injury as measured by transfusions and operative management. Thirty-one CT grades did not correlate with operative findings (84%). Four patients had intrahepatic hematomas that were not discovered at operation. Twelve lacerations were graded too high by CT and 15 too low. Of these 15, ten CT scores were at least two grades lower than operative findings. Injuries around the falciform ligament occurred in three of the low misclassifications. One patient with intrahepatic hematoma developed hepatic artery pseudoaneurysm. We conclude that the HIS readily characterizes operative findings of hepatic lacerations and that increasing operative grade correlates well with transfusion requirements and operative management. CT can define intrahepatic hematomas, but does not correlate well with hepatic lacerations. Extreme caution is required when using CT alone to define "minimal" liver injury for prospective management of blunt trauma victims.

Elective preperitoneal or posterior repair for recurrent groin hernias and primary femoral hernias has been shown to be a technically advantageous approach. In addition to the ease of inguinal floor and femoral canal assessment, scar tissue from prior anterior herniorrhaphy can be avoided. The emergency management of the acutely incarcerated or strangulated hernia of the groin using this approach has not been addressed. During a 30-month period, all patients with a diagnosis of acute incarceration of a groin hernia (n = 28) were surgically managed using either the anterior approach (AA) (n = 14) or the preperitoneal approach (PA) (n = 14). Two patients with strangulated intestine in the AA group required an additional midline incision for bowel evaluation and resection. Intestinal evaluation was easily accomplished through the same incision in four patients in the PA group. The preperitoneal approach also allowed proximal control of incarcerated or strangulated viscera, thus avoiding excessive manipulation of gangrenous or necrotic intestine, potential spillage of infected contents into the peritoneal cavity, and entry of bacteria, toxins, potassium, and the metabolic waste products of anaerobic metabolism into the systemic circulation during hernia reduction. There have been no recurrences in either group, and minor complications, such as wound infection and cellulitis, in the two groups are not statistically different.

A retrospective analysis was undertaken of 113 patients with biopsy-proven neoplasia of the extraperitoneal rectum and anus occurring between 1970 and 1975. Common initial symptoms included bleeding, constipation, and diarrhea; colon obstruction was the initial symptom in only ten cases. Adenocarcinoma occurred in 90 per cent of cases while lesions such as epidermoid cancer, carcinoid, and melanoma were encountered rarely. Operative treatment consisted of abdominoperineal resection (APR) in 60 cases, colostomy alone in 26 cases, anterior resection 13 cases, and electrocoagulation in four cases. Ten patients refused operative therapy. Of patients undergoing APR, 7 per cent died in the perioperative period. Postoperative morbidity included infection, impotence, bladder dysfunction, and perineal complications. The single most important factor contributing to this high morbidity was perineal wound management: 34 patients managed by the open method sustained a 47 per cent complication rate while the 26 patients with closed and adequately drained wounds had only a 15 per cent complication rate.

Patients requiring amputation of the lower extremity for arteriosclerosis are at high risk for the development of venous thrombosis and pulmonary embolism. Inapparent venous thrombosis was discovered in the amputated leg at operation in eight patients. Pulmonary embolism was documented by angiogram or at autopsy in ten patients. The majority of emboli discovered in this study was not suspected by the physician responsible for the care of the patient. The perfusion lung scan in this elderly group of patients had a false-positive rate of 60 per cent, while a normal lung scan was strong evidence against pulmonary embolsim. Although imperfectly randomized, the prophylactic use of low molecular weight dextran in this study did not decrease the incidence of pulmonary embolism. The pulmonary arteriogram proved a safe procedure in the elderly and should be used before therapy is initiated for suspected pulmonary embolism.

During the 40 years from 1945 to 1984, 159 occurrences of sigmoid volvulus in 140 patients were diagnosed and managed. Treatment modalities gradually evolved from primarily operative decompression in the first 20 years to selective, sigmoidoscopic, nonoperative reduction in the most recent 10-year period. Operative reduction was associated with a 10 per cent mortality, while no deaths were associated with nonoperative reduction. A 60 per cent mortality was noted when gangrenous bowel was present. In the most recent 10-year period, 71 per cent of cases were associated with neuropsychiatric diseases, and one third had a previous episode of sigmoid volvulus. The diagnosis was made on the initial plain abdominal radiograph in 60 per cent, and nonoperative sigmoidoscopic reduction attained in 95 per cent. Following nonoperative reduction, elective resection was performed during the same hospitalization with a 5 per cent mortality. Initial management of sigmoid volvulus should consist of nonoperative attempts at reduction with operative reduction reserved for refractory cases or those with ischemic bowel. Elective resection can be safely performed during the same hospitalization.

The management of lower gastrointestinal bleeding has evolved from a number of technological advances allowing precise diagnosis and localization of the bleeding site. This study of 40 angiographically demonstrated lower gastrointestinal bleeding lesions reinforces much of the data indicating the diagnostic and therapeutic trends. Twenty-four patients had bleeding diverticula with angiographic demonstration in 11 patients. Seven cases of vascular ectasia were identified, and nine patients had a variety of significant bleeding sites other than the two main sites that were listed. Pitressin was useful for control of bleeding in six of seven diverticular patients but was less useful in the vascular ectasia group in which only one patient was actively bleeding. Total abdominal colectomy and segmental resection were successful in control of hematochezia in 24 of 25 operative cases. Sixteen patients did not require surgical treatment.

The surgical experience with hyperparathyroidism at this institutition of 32 cases since January 1969, has been presented. The age range, sex ratio, associated disease and location of adenomas follows previously reported patterns. Analysis of various preoperative laboratory data confirm that no single test consistently can establish the diagnosis of hyperparathyroidism. At exploration, all glands should be identified and all adenomas removed. Subtotal parathyroidectomy consisting of excision of 3 3/4 glands should be performed for hyperplasia.
