Background: When esophagocardiomyotomy (ECM) is performed for achalasia, a complementary antireflux procedure of the surgeon's choice is usually performed to minimize postoperative gastroesophageal reflux. This retrospective analysis describes patients after laparoscopic ECM, most of whom had a modified Dor fundoplication., Methods: Between 1994 and 2001, 81 patients with achalasia of the esophagus had laparoscopic ECM. We have previously described the use of intraoperative endoscopy to verify completion of ECM in a cohort of 48 patients who had either Toupet fundoplication (n = 25) or floppy Dor fundoplication (n = 23). Since then floppy Dor fundoplication has been the preferred antireflux procedure for ease of performance and safety reasons. This article describes the floppy Dor fundoplication as we have performed it since 1997, anchoring the wrap to both crura of the hiatus. In addition, the anterior gastric wall is sutured to the anterior rim of the esophageal hiatus, avoiding creation of the paraesophageal hernia that occurs if the gastric wall abuts the entire the length of a long ECM., Results: During the 1- to 70-month follow up period (mean 45 months), patients who were symptomatic were evaluated by radiographic, manometric, or endoscopic methods; pH studies were not done systematically. The 70% of patients who could be evaluated had postoperative quality of life and symptom assessment interviews that revealed willingness to repeat the operation. Overall satisfaction was high (8.4/10 where 10 is perfect); moderate dysphagia was seen in 11 (16%) 3 to 16 months postoperatively, but patients reverted to a satisfaction score of 8.2 after endoscopic dilation. Occasional heartburn was present in 15 (26%) patients with regular, 5-use proton pump inhibitors (PPI), including 1 with Barrett's esophagus. Others use these medications for gastric disorders. No patient has had cancer of the esophagus develop, but endoscopic surveillance has been inconstant., Conclusions: Swallowing was improved in patients without sigmoid esophagus and overall satisfaction was high. New-onset heartburn is an unpredictable problem that can be treated in most patients. Endoscopic dilatation may be required at intervals after ECM-fundoplication for bridging fibrosis at the cardia, but has not required reoperation, as a rule. Laparoscopic ECM is an attractive operation for achalasia.

Background: The unexpected intraoperative finding of a cancerous gallbladder has become particularly problematic, because cancer recurs rapidly after laparoscopic cholecystectomy. It would be desirable to identify the patients of greatest risk for gallbladder cancer before operation. After several elderly patients presenting with acute cholecystitis were found to have gallbladder cancer, we performed the following study., Methods: Records of patients (60 years of age or older, 1987 to 1995) with an admitting diagnosis of acute cholecystitis and symptoms including right upper quadrant pain, nausea, vomiting, fever, and leukocytosis were reviewed., Results: Eighty patients were included in the study. Carcinoma involving the gallbladder was found in seven patients; six had primary and one had metastatic carcinoma. The 73 patients without cancer underwent cholecystectomy. The differences between the noncancer and cancer patients included age (68 +/- 7 versus 74 +/- 8 years, p < 0.05), total bilirubin (mg/dl, 1.5 +/- 1.5 versus 3.7 +/- 3.4, p < 0.01), alkaline phosphatase (IU/L, 179 +/- 132 versus 369 +/- 226, p < 0.01), and aspartate aminotransferase (IU/L, 77 +/- 93 versus 158 +/- 157, p < 0.05)., Conclusions: Additional work-up and open cholecystectomy should be considered in elderly patients presenting with apparent acute cholecystitis, especially when liver functions are abnormal.

Background: Effective surgical treatments for achalasia of the esophagus facilitate swallowing by division of muscles that fail to relax normally during swallowing. If esophagocardiomyotomy is performed, a complementary antireflux procedure is mandatory to prevent postoperative gastroesophageal reflux. We evaluated patients who had undergone a circumferential antireflux procedure after esophagocardiomyotomy to determine the effects of this procedure in patients with an aperistaltic esophagus., Methods: During the past 15 years we treated 94 patients with achalasia by use of pneumatic dilation (66), esophageal myotomy (19), or esophagocardiomyotomy with floppy Nissen fundoplication (24). Achalasia was defined by radiographic and manometric criteria until 1986 when computerized axial manometry of the esophagus was initiated, providing information about the three-dimensional contour and "volume" of the lower esophageal sphincter in addition to the usual manometric data., Results: Dysphagia was effectively relieved in all, and neither postoperative reflux nor esophageal obstruction was observed after esophagocardiomyotomy followed by floppy Nissen fundoplication. The measured lower esophageal sphincter pressures and sphincter volume were markedly reduced., Conclusions: Esophagocardiomyotomy with floppy Nissen fundoplication is an effective treatment for achalasia; clinical evidence of obstruction of the esophagus was not seen, and manometric data were typical of a weakened sphincter.

Congenital cysts, sometimes referred to as nonparasitic biliary cysts, are not unusual findings in the liver parenchyma, but they have not been previously described in the common bile duct. This clinical report describes a 41-year-old woman with obstructive jaundice that was caused by congenital cysts. The patient had obstruction of the middle portion of the common bile duct; therefore the major differential diagnostic considerations were cholangiocarcinoma, cancer of the pancreas, or true biliary cysts. Congenital cysts, retention cysts, and neoplastic cysts cannot be differentiated from other true cysts preoperatively. Diagnosis can only be established by microscopic examination after surgical excision.

This prospective, randomized study of selective vagotomy with antrectomy (SVA) versus proximal gastric vagotomy (PGV) for patients with duodenal ulcer compares the incidence of recurrent duodenal ulcer and postoperative morbidity during a 4- to 12-year follow-up period. In 46 patients with SVA there were no recurrent ulcers, but 26% of these individuals had serious digestive problems that were not amenable to medical treatment. The 40 patients with PGV had eight recurrent ulcers (20%), but five of these were found in the first 15 patients (33%) compared with three in the 25 patients (12%) who had operations after the need for extensive periesophageal denervation was discovered in the mid-1970s. Most recurrent ulcers were amenable to medical treatment, but 5% of the patients who had PGV had postoperative dysphagia that required periodic bougienage. The data are consistent with several interpretations, depending on the bias of the individual. However, based upon the fact that recurrent ulcers could be managed nonoperatively after PGV versus the lack of effective treatments for postgastrectomy complaints after SVA, it is reasonable to consider wider use of PGV. There are reasons to believe that the variable ulcer recurrence rates after PGV can be explained by subtle differences in operative technique, including those based upon use of the Congo red test for completeness of vagotomy. Unlike SVA, PGV remains an operative procedure in evolution that requires further clinical investigation. At this time either operation can be applied if both the surgeon and the patient have a clear understanding of the possible effects.

Operative ultrasonography and operative radiographic cholangiography were compared for diagnostic effectiveness with regard to their ability to screen the common bile duct for the presence of calculi. We performed real-time B-mode ultrasonography and cholangiography using two injections of contrast material. In 350 patients, 349 ultrasonic and 285 cholangiographic examinations were performed with technically satisfactory results. The sensitivity, specificity, efficiency, and predictability of a negative test were at a high and comparable level for the two diagnostic procedures. However, the predictability of a positive test for ultrasonography of 91.8% was significantly greater (P less than 0.02) than the predictability of 73.2% for cholangiography. Since predictability of a positive test is based on common duct exploration rather than presumptive evidence of a clinical course, this test may be more valid than the other measures to determine diagnostic effectiveness. The advantages of ultrasonography, which are superior accuracy, favorable image qualities, reduced invasiveness, increased safety, avoidance of contrast material, and lower cost, were contrasted with the problems of ultrasonography, which included a slow learning curve for performance and interpretation of the technique and the limited availability of dedicated ultrasound equipment for surgical operations. We concluded that the advantages outweighed the problems and that operative ultrasonography of the common duct warrants wider application in clinical surgery.

The optimal treatment for obstructing duodenal ulcer is controversial because of questions about the efficacy of proximal gastric vagotomy (PGV) in controlling the primary ulcer diathesis. Impressed with the theoretic advantages of PGV with drainage as a primary treatment for this problem, we have treated 37 suitable patients by this approach. All patients underwent endoscopic examination and barium meal study that proved the diagnosis. PGV, including division of the gastroepiploic nerves as indicated by intraoperative testing, was followed by Jaboulay gastroduodenostomy (18), Finney pyloroplasty (12), Heineke-Mikulicz pyloroplasty (3), anterior hemipylorectomy (2), duodenoplasty (1), and gastroenterostomy (1). No recurrent ulcers were seen during a mean follow-up of 4.6 years. Three patients had mild early dumping at infrequent intervals. Bilious vomiting, alkaline gastritis, and other postgastrectomy complaints were recorded infrequently. PGV with drainage is a good treatment for the obstructing ulcer and does not have as many morbid risks as alternative operative procedures.
