RESUMO

OBJECTIVE: To determine the variation in number, size, and symptoms in patients with polypoid lesions of the gallbladder. SUMMARY BACKGROUND DATA: A polypoid lesion is any elevated lesion of the gallbladder mucosa. Several studies have been reported in patients undergoing cholecystectomy, but little information exits regarding the natural history of these lesions in nonoperated patients. METHODS: A total of 111 patients with ultrasound diagnosis of polypoid lesions smaller than 10 mm were followed up by clinical evaluation and ultrasonography. Twenty-seven patients underwent cholecystectomy. RESULTS: There was no difference in terms of gender. Nearly 80% of the lesions were smaller than 5 mm; they were single in 74%. In nonoperated patients, 50% remained of similar size at the late follow-up, 26.5% increased in number and size, and 23.5% shrank or disappeared. Among the operated patients, 70% corresponded to cholesterol polyps. None of the patients developed symptoms of biliary disease or gallstones or adenocarcinoma. CONCLUSIONS: Ultrasound is useful in the follow-up of patients with polypoid lesions of the gallbladder. Lesions smaller than 10 mm do not progress to malignancy or to development of stones, and none produced symptoms or complications of biliary disease.

RESUMO

BACKGROUND: The "post cholecystectomy" syndrome comprises a series of vague symptoms referred by patients subjected to this surgical procedure. These symptoms are unspecific and their association with the operation is dubious. AIM: To assess the frequency of digestive symptoms among patients subjected to a cholecystectomy ten years ago. PATIENTS AND METHODS: One hundred patients subjected to a cholecystectomy between 1987 and 1990, were contacted by mail. They were invited to a clinical interview and to an abdominal ultrasound examination. RESULTS: Two invited patients had died of an acute myocardial infarction. Therefore, 98 patients (78 women), aged 30 to 85 years old, were assessed. Seventy two percent had diverse dyspeptic symptoms, 90% had no food intolerance and 94% had gained weight after the operation. Ninety six percent was satisfied with the surgical results, 3% had severe symptoms due to gastroesophageal reflux or depression. One patient had a residual choledocholithiasis and refused any treatment. CONCLUSIONS: Cholecystectomy is well tolerated and has good long term results.

RESUMO

BACKGROUND: Morbidly obese subjects have a high incidence of complications. The poor results of dietary treatments, has prompted the search of new therapies for obesity and among these, surgical procedures. AIM: To report the long term results of horizontal gastroplasty with Roux en Y anastomosis in morbidly obese subjects. PATIENTS AND METHODS: Fifty patients with an initial body mass index of 41.3 +/- 6 kg/m2 have been subjected to a horizontal gastroplasty with Roux en Y anastomosis. During the study period, surgical techniques were modified, reducing the gastric pouch size, adding a truncal vagotomy, cholecystectomy, and increasing the length of the Roux en Y loop from 70 to 100 cm. Twenty five patients have been followed for two years. RESULTS: There was no operative mortality and one patient had an anastomotic leak that required 35 days of hospitalization. During follow up, in one patient, the stapled suture line loosened. After two years of follow up, weight decreased from 112 +/- 19 to 77.2 +/- 14 kg. CONCLUSIONS: Horizontal gastroplasty with Roux en Y anastomosis achieved an adequate weight loss with a low rate of complications in this group of morbidly obese subjects.

RESUMO

BACKGROUND: Sixty percent of adults has typical symptoms of gastroesophageal reflux in Chile. AIM: To report the clinical and laboratory features of patients with gastroesophageal reflux. PATIENTS AND METHODS: Five hundred thirty-four patients (255 male) with gastroesophageal reflux were included in a prospective protocol that included clinical analysis, manometry and endoscopy in all patients, barium swallow in 427, scintigraphy in 195, acid reflux test in 359, 24 h pH in 175, and differential potential of gastroesophageal mucosa in 73 patients. RESULTS: There was no correlation between the severity of symptoms and the endoscopical severity. Patients with Barret esophagus were 12 years older, were male in a greater proportion and had a higher proportion of manometrically incompetent sphincters than patients with esophageal reflux but without esophagitis or with erosive esophagitis. Severity of acid reflux, measured with 24 h pH monitoring was proportional to the endoscopical damage of the mucosa. There was a close relationship between the mucosal change limit determined with differential potentials and with endoscopy. No short esophagi were found. CONCLUSIONS: Patients with symptoms of gastroesophageal reflux must be assessed using several objective measures to determine the severity of their pathological alterations.

RESUMO

A prospective study was performed in 190 control subjects and in 236 patients with different degrees of endoscopic esophagitis in order to determine the prevalence of Helicobacter pylori infection at duodenal gastric and esophageal mucosa and its correlation with histological findings. All patients with pathologic gastroesophageal reflux had 24-h pH monitoring studies confirming the presence of acid reflux into the esophagus. Besides the endoscopic findings, biopsies were taken from the duodenal bulb, gastric antrum, gastric fundus and distal esophagus or at the specialized columnar epithelium in patients with Barrett's esophagus. Patients with pathological gastroesophageal reflux were divided into three groups: 55 with absence of endoscopic esophagitis (gastroesophageal reflux), 81 patients with erosive esophagitis and 100 patients with Barrett's esophagus. There was no H. pylori infection present at duodenal or esophageal mucosa or at the specialized columnar epithelium of the distal esophagus in any case. The prevalence of H. pylori infection at gastric antrum was similar in controls and in any group of patients with reflux disease (20-25% of H. pylori infection). No differences in age and sex distribution were seen. H. pylori infection at gastric fundus was very low (less than 5%). The presence of HP infections was correlated with the finding of chronic active superficial or athrophic gastritis while, in the absence of H. pylori infection, gastric mucosa was normal. In the presence of intestinal metaplasia, no H. pylori infection occurred. Based on these findings, it seems that there is no significant evidence for an important pathogenic role for H. pylori infection in the development of pathologic chronic gastroesophageal reflux, erosive esophagitis or Barrett's esophagus, and the presence of antral gastritis in patients with Barrett's esophagus is closely related to the presence of H. pylori infection, and probably not related to an increased duodenogastric reflux.

RESUMO

BACKGROUND: In Chile, cholelithiasis is a serious public health problem and there are no studies about its natural history. AIM: To assess the long term evolution of patients with symptomatic and asymptomatic cholelithiasis. PATIENTS AND METHODS: Ninety two patients with cholelithiasis (57 female), aged 15 to 80 years old and that were not operated, were followed during a period of 9 to 14 years. RESULTS: Thirteen patients were initially asymptomatic. Of them, seven bad complications or symptoms during follow-up and two were operated. Among the 69 symptomatic patients, 38 (55%) were not operated during follow-up, and seventeen (25%) did not have symptoms again. Ten patients died during follow-up, four due to complications of biliary tract stones. CONCLUSIONS: The present finding suggest that the evolution of cholelithiasis in Chile is more aggressive than abroad, and an early surgical treatment is warranted.

RESUMO

BACKGROUND: Laparoscopic antireflux surgery is a minimally invasive procedure that should have similar results than classical surgical treatment. AIM: To report the results of a prospective study of laparoscopic antireflux surgery in patients with gastroesophageal reflux. PATIENTS AND METHODS: Thirty two patients with gastroesophageal reflux and without Barret's esophagus, were subjected to endoscopy, manometry and measurement of intraesophageal pH before and after laparoscopic surgery. RESULTS: There were no postoperative deaths or complications. Gastroesophageal sphincter pressure and abdominal sphincter length increased from 9.1 +/- 3.9 to 13.0 +/- 3.5 mm Hg and from 8.1 +/- 6.2 to 13.5 +/- 5.4 cm after surgery (p < 0.01). There was a decrease in acid reflux in 82% of patients. CONCLUSIONS: Laparoscopic antireflux surgery reproduces exactly the results of open surgical procedures.

RESUMO

BACKGROUND/AIMS: The number of colonies of bacteria and the number of pyocites present per ml of choledochal bile was studied. PATIENTS AND METHODS: There were 42 controls, 100 patients with symptomatic gallstones, 42 patients with common duct stones without cholangitis and 24 patients with common duct stones and acute cholangitis. RESULTS: Control subjects had no bacteria present at gallbladder bile. Only 3% of patients with gallstones had more than 10(5) colonies per ml which increased to 36% in patients with common duct stones without cholangitis and to 84% among patients with acute cholangitis (p < 0.001). There were more polybacterial flora among patients with acute cholangitis and anaerobic bacteria were not seen in patients with gallstones. Patients with acute cholangitis had significantly more pyocites present at choledochal bile. CONCLUSION: There is a direct correlation between the number of colonies present per ml of choledochal bile and the severity of biliary tract disease. Patients with acute cholangitis had significantly more pyocites present at choledochal bile compared to gallstones or patients with CBD stones without cholangitis.

RESUMO

OBJECTIVES: To determine the simultaneous prevalence of bacteria in bile from the gallbladder and common bile duct and to determine the influence of the number of stones present on bacteriologic findings. METHODS: A prospective study was performed in 467 subjects divided into seven groups: 42 control subjects with normal biliary tracts, 221 patients with symptomatic gallstone disease, 12 patients with hydropic gallbladder, 52 patients with acute cholecystitis, 67 patients with common bile duct stones without cholangitis, 49 patients with common bile duct stones and acute cholangitis, and 24 patients with previous cholecystectomy and common bile duct stones. In all except controls, bile samples from the gallbladder and common bile duct were taken simultaneously for aerobic and anaerobic cultures. RESULTS: Control subjects had no bacteria in gallbladder bile. Patients with gallstones, acute cholecystitis, and hydropic gallbladder had similar rates of positive cultures in the gallbladder and common bile duct, ranging from 22% to 46%, but the rate was significantly higher in patients with common bile duct stones without cholangitis (58.2%). Patients with cholangitis or previous cholecystectomy had a high rate of positive cultures of common duct bile (93% to 100%). Age greater than 60 years had a significant influence on the rate of positive bile cultures. There was no relationship between the number of stones in the gallbladder or common bile duct and the percentage of positive cultures. In 98% of the patients, the same bacteria were isolated from gallbladder and common duct bile. CONCLUSIONS: In normal subjects, no bacteria were present in the biliary tract. Among patients with common bile duct stones, there was an increasing percentage of positive cultures according to the severity of the disease. Age had an important influence, but sex and the number of common bile duct stones had no influence on positive cultures.

RESUMO

BACKGROUND/AIMS: This prospective study evaluates the peristaltic activity of the thoracic esophagus in a group of patients with gastroesophageal reflux disease grouping them according to the endoscopic findings. MATERIALS AND METHODS: The peristaltic activity and the manometric features of the lower esophageal sphincter were prospectively evaluated in 109 controls and 321 patients with reflux esophagitis, divided according to the degree of endoscopic esophagitis employing Savary's classification. RESULTS: Gastro esophageal sphincter pressure was progressively lower according to the severity of the tissue damage. Motor peristaltic activity of the thoracic esophagus measured by several different parameters was significantly altered in Grade IV esophagitis compared to other groups (p < 0.01). The manometric changes were more pronounced at the distal esophagus compared to the proximal esophagus. The percentage of patients with severe motor disturbances, defined as lower esophageal sphincter (LES) pressure less than 6 mm, less than 50% of peristaltic waves after swallowing and amplitude of contractile waves of less than 50 mmHg were significantly greater in patients with severe esophageal injury (p < 0.001). CONCLUSION: Gastroesophageal esophageal reflux may exhibit a wide spectrum of motor disturbances in the distal part of the esophagus even before the presence of the tissue damage, but it increases in proportion to the severity of endoscopic esophagitis.
