Esophagopleural fistula: a complication of chest intubation for empyema.

This report documents the first recorded patient in the recent literature with an esophageal perforation and an esophagopleural fistula following chest intubation for empyema. It was treated successfully by conservative method with feeding gastrostomy. It is important to realize that tube thoracostomy drainage is not an innocuous procedure and to be alert to this complication, especially in the presence of empyema.

A nationwide study of the use of self-expanding stents in patients with esophageal cancer in Sweden.

BACKGROUND AND STUDY AIMS: Endoscopic insertion of self-expanding metal stents is used for palliative treatment of esophageal and cardia cancer, but the safety profiles, and the influence of age, sex, and hospital volume have not previously been evaluated in a population-based setting. PATIENTS AND METHODS: A retrospective population-based study was conducted, including all patients treated with esophageal stenting for malignant disease recorded in Swedish national registries in the period 1997 - 2000. Patients with esophageal or cardia cancer were identified in the cancer registry, and those treated with esophageal stenting were selected from the in-patient registry. Survival and emigration were assessed using the registries for causes of death and emigration, respectively. Procedure-related complications were assessed by reviewing medical records. RESULTS: Among 1052 registered patients with esophageal or cardia cancer, 402 patients (38 %), with a median age of 74 years, were treated with esophageal stenting. After treatment, the median in-hospital stay was 7 days, and the median survival was 100 days. Survival times were similar between age groups and sexes. Stenting was conducted at 38 Swedish hospitals, with a range of 1-59 procedures at each hospital. Among 152 (38 %) patients who were evaluated for complications, 41 (27 %) had complications of some type, while 20 (13 %) experienced direct procedure-related complications. No differences in complication frequencies were found between high-volume and low-volume centers. There were only two procedure-related deaths (1 %), both due to esophageal perforation. No reduction in the median survival time was found in patients with complications. CONCLUSIONS: Treatment with self-expanding metal stents is a widely used and reasonably safe procedure among patients with malignant dysphagia, independent of sex, age, or hospital volume in Sweden.

Radiographic evaluation of achalasia immediately after pneumatic dilatation with the Rigiflex dilator.

Radiographic evaluation of the lower esophagus was done immediately after pneumatic dilatation using the Rigiflex dilator in 34 patients (24 men, 10 women; mean age, 55 years) with achalasia. The dilator was positioned across the esophagogastic junction using fluoroscopy and the balloon was inflated for 1 min. The esophagus was intubated and injected sequentially with water-soluble and barium contrast materials. Radiographic analysis included changes in the appearance of the caliber and contour of the esophagogastric junction, rate of esophageal emptying, and presence of complications. In 23 patients with predilatation esophagrams, the mean esophagogastric junction caliber increased from 4.7-7.6 mm following dilatation. The postdilatation esophagrams in 33 patients showed a smooth contour in 22 (67%) and immediate esophageal emptying in 26 (79%). Esophageal perforation occurred in one (3%) patient and intramural hematoma in one (3%). Clinical follow-up (mean, 7 months) was available in 29 patients and 23 (79%) had symptomatic improvement. Five of the six patients who did not improve clinically all had previous Heller myotomy, pneumatic dilatation, or both.

[Endoscopic prosthesis insertion in the palliative treatment of malignant esophageal stenosis. (Endoscopic esophageal prosthesis)].

We report our experience with endoscopic esophageal prosthesis in the treatment of 82 patients with advanced malignant oesophageal stenosis. The cause of the stenosis was an esophageal or esophagogastric cancer in 75 cases and a bronchogenic cancer in 7 patients. In 18 cases a tracheobronchial fistula was also present. A silicone tube (Atkinson) was used in 58 patients, a polyvinyl tube (Wilson-Cook) in 22 cases and a self-expanding tube in the remaining 2 patients. There was no technical failure in the insertion of the prosthesis. A normal feeding was possible in 71 of the 82 patients (86%) within 48 after the intubation. Major complications occurred in 8 cases (9.7%), 4 patients with esophageal perforation and 4 cases with aspiration bronchopneumonia. Postoperative mortality rate was 7.3%, one patient with perforation, 3 cases with aspiration bronchopneumonia and 2 patients with sepsis. The prosthesis partially displaced in 9 cases, but could be endoscopically replaced in all of them. The displacement of the prosthesis was complete in 3 patients, one of which needed a surgical procedure to remove the tube. The prosthesis was bunged up by a solid meal bolus in 4 cases, but an endoscopic procedure was successful in removing the bolus. Therapy with laser was necessary in two cases with self-expanding prosthesis obstructed by tumoral growth. We conclude that, in malignant esophageal stenosis, the endoscopic implantation of esophageal endoprosthesis is an effective, cheap and relatively safe palliative therapeutic alternative with a low postoperative mortality rate.

[Portal thrombosis: early complication of azygo-portal disconnection in the treatment of bleeding esophageal varices].

The authors studied 30 patients with bleeding from esophageal varices due to portal hypertension. They underwent the disconnection of portal and azygos veins and splenectomy. The immediate postoperative complications were: portal thrombosis in four patients (13.3%); subphrenic abscess in two (6.6%); pulmonary embolism in one (3.3%) and esophageal perforation in one (3.3%). The manifestations of portal thrombosis were ascites, and fever (without leukocytosis). One patient with portal thrombosis who had intractable ascite was submitted to peritoneovenous shunting.

Achalasia in a sixty-four-year-old man.

Achalasia is an esophageal motility disorder characterized by increased lower esophageal sphincter pressure and absence of peristalsis in the lower esophagus. Patients typically present with complaints of progressive difficulty swallowing over a period of several years. Diagnosis is confirmed by esophageal manometry. Complications of achalasia include esophagitis, aspiration and possibly an increased risk of esophageal carcinoma. Medical treatment options include pneumatic dilatation, esophageal bougienage, nitrates, calcium channel blockers and botulinum toxin injections. The primary method of surgical treatment is the Heller myotomy, in which longitudinal incisions are made in the muscle fibers of the lower esophageal sphincter to reduce sphincter pressure. Frequently, a fundoplication is performed in addition to the myotomy to decrease the likelihood of development of gastroesophageal reflux. In recent years, the Heller myotomy has been performed both thoracoscopically and laparoscopically. An additional development has been the placement of an endoscope in the esophagus to provide transillumination during surgery; intraoperative endoscopy allows improved assessment of the depth of myotomy incisions and reduces the risk of esophageal perforation. The case report below describes a 64-year-old-man with achalasia who presented with persistent dysphagia despite multiple attempts at medical treatment. A laparoscopic Heller myotomy with Toupet fundoplication was performed with subsequent eradication of symptoms. A discussion of the epidemiology, etiology, clinical presentation, diagnosis and treatment of achalasia follows the case report.

Gastric transposition for esophageal replacement in children: experience with 41 consecutive cases with special emphasis on esophageal atresia.

OBJECTIVE: To evaluate the authors' experience with gastric transposition as a method of esophageal replacement in children with congenital or acquired abnormalities of the esophagus. SUMMARY BACKGROUND DATA: Esophageal replacement in children is almost always done for benign disease and thus requires a conduit that will last more than 70 years. The organ most commonly used in the past has been colon; however, most series have been fraught with major complications and conduit loss. For these reasons, in 1985 the authors switched from using colon interpositions to gastric transpositions for esophageal replacement in infants and children. METHODS: The authors retrospectively reviewed the records of 41 patients with the diagnoses of esophageal atresia (n = 26), corrosive injury (n = 8), leiomyomatosis (n = 5), and refractory gastroesophageal reflux (n = 2) who underwent gastric transposition for esophageal replacement. RESULTS: Mean +/- SE age at the time of gastric transposition was 3.3 +/- 0.6 years. All but two transpositions were performed through the posterior mediastinum without mortality or loss of the gastric conduit despite previous surgery on the gastric fundus in 8 (20%), previous esophageal operations in 15 (37%), and previous esophageal perforations in 6 (15%) patients. Complications included esophagogastric anastomotic leak (n = 15, 36%), which uniformly resolved without intervention; stricture formation (n = 20, 49%), all of which no longer require dilation; and feeding intolerance necessitating jejunal feeding (n = 8, 20%) due to delayed gastric emptying (n = 3), feeding aversion related to the underlying anomaly (n = 1), or severe neurological impairment (n = 4). No redo anastomoses were required. CONCLUSIONS: Gastric transposition reestablishes effective gastrointestinal continuity with few complications. Oral feeding and appropriate weight gain are achieved in most children. Therefore, gastric transposition is an appropriate alternative for esophageal replacement in infants and children.

[Major esophageal hemorrhages of unusual origin. A poorly known entity].

Nine cases of severe gastrointestinal haemorrhage as the presentation of oesophageal lesions are reported. Haemorrhages complicating oesophageal varices, carcinoma of the oesophagus and oesophageal surgery were eliminated from the study, as were haemorrhages associated with hiatal hernias or Mallory-Weiss syndrome. Amongst these 9 cases of severe haemorrhage, 5 were due to an ulcer of the oesophagus, 2 to acute oesophagitis, 1 to rupture of the oesophagus and one to a traumatic aneurysm of the aorta rupturing into the oesophagus. The location and cause of bleeding were determined only 3 times before operation and only when a fibroscopic examination had been carried out. At fibroscopy, an irregular lesion responsible for a severe haemorrhage has every chance of being a benign ulcer and not a carcinoma. Treatment directed at the aetiology was carried out in 6 cases and success obtained in 3 patients. The aetiological diagnosis who was not made in 3 patients, who died. The aetiology, diagnosis and therapeutic approach required in such cases of severe haemorrhage of oesophageal origin are considered. In the light of these cases, a possible oesophageal aetiology should be considered as a possible cause of an unexplained severe gastrointestinal haemorrhage. An attempt at proving such a hypothesis by fibroscopy is necessary and, in general, urgent thoracotomy since the bleeding is in most instances of arterial origin.

[Combined radiotherapy and chemotherapy for the treatment of esophageal cancer].

Eight patients with esophageal cancer were treated by a new treatment schedule consisting of low dose irradiation, crescendo cisplatin and bleomycin polyacrylate pasta. As monitored endoscopically, therapeutic responses were satisfactory: seven out of 8 patients have survived for a range of 3 to 20 months and still active at work or cancer-free. However, one patient suffered from a second malignancy of adenocarcinoma of the upper esophagus different from the initial squamous cell carcinoma at the lower esophagus which had successfully been treated 3 months before. The present therapeutic design aims at treatment of lymphatic spreads in the adjacent structures as well as the original tumor in the esophagus and submucosal invasions. It is basically a consecutive, multimodal integration of selective concentration of therapeutic effects (extensive radiotherapy, topical application of bleomycin polyacrylate pasta, lymphatic chasing with colloidal bleomycin, and spatial concentration of cisplatin as the result of radiation-induced inflammation), perpetuation of the repairable DNA damage, and biological amplifications (protection against esophageal perforation with polyacrylate coating, and specific cancer cell recruitment). Application of the present therapeutic design is being expanded to the treatment of cancer of other specific sites such as the head and neck tumors and rectal cancer with undeniable prospects.

Sixteen years follow up of achalasia: a prospective study of graded dilatation using Rigiflex balloon.

Pneumatic balloon dilatation is the treatment of choice for esophageal achalasia. Rigiflex (Microvasive, Watertown, MA) polyethylene balloon dilators have been used with varying success and complications. The aim of this study was to evaluate the efficacy of graded balloon dilatation, to achieve symptomatic improvement in patients with achalasia. From January 1987 until the end of December 2003, 300 patients were evaluated and treated for achalasia, with 30 mm balloons. Patients who did not achieve satisfactory symptomatic responses during follow up underwent repeat dilatation with 35-mm balloons. They were studied at the onset then at 1 and 6 month intervals and then yearly for postdilatation symptom evaluation for dysphagia, regurgitation, night cough and heartburn. Baseline and 5-min postdilatation barium swallow studies were obtained to compare barium height and width for efficacy of dilatation and to evaluate for complications. No patients developed cancer of the esophagus in 16 years follow up. Barium height, width, composite symptom score and weight improved significantly during follow up. Two patients, who needed repeat dilatation with 35-mm balloons, developed esophageal perforation; one was successfully managed with intensive medical care management, whereas the other patient died despite surgical intervention. The authors conclude that pneumatic balloon (Rigiflex) dilatation for achalasia of the esophagus is a successful first option, when applied in an incremental balloon size to achieve desired results in symptomatic relief.

Zenker's diverticulum associated with multilevel cervical osteomyelitis.

STUDY DESIGN: A case report of cervical osteomyelitis possibly associated with a Zenker's diverticulum perforation. OBJECTIVES: To present clinical, radiologic, and surgical findings of a cervical osteomyelitis due to a Zenker's diverticulum perforation. SUMMARY OF BACKGROUND DATA: A 56-year-old patient was in an intensive care unit for a severe head injury. He was fed via a nasogastric tube. Four months later he developed a pyogenic cervical vertebral infection. METHODS: Plain films and magnetic resonance imaging showed a diffuse cervical osteomyelitis. Investigation of his dysphagia revealed a Zenker's diverticulum. RESULTS: After administration of antibiotics and surgical treatment of the diverticulum, the cervical infection resolved. Plain films and magnetic resonance imaging showed healing with vertebral fusion. CONCLUSIONS: Cervical osteomyelitis is uncommon. Only one case of direct contamination leading to cervical vertebral osteomyelitis after esophageal perforation has been previously described. Direct contamination of the prevertebral soft tissues by bacteria traveling through the fistula may have occurred. The development of vertebral osteomyelitis in this case is consistent with the hypothesis of direct contamination. Management relies on appropriate antimicrobial therapy and surgical management of the diverticulum. The association of Zenker's diverticulum with vertebral osteomyelitis and discitis is a unique, previously undescribed situation.

[Pneumatic dilatation in esophageal achalasia. Report of 61 cases].

UNLABELLED: To assess the interest of pneumatic dilatation in patients with achalasia. MATERIAL AND METHODS: The work has interested 61 patients with achalasia who underwent pneumatic dilatation using polyethylene balloon (Rigiflex) dilators. 74 sessions of dilatation were performed and 13 patients underwent 2 sessions of dilatation (21%). One patient presented un esophageal perforation requiring a surgical treatment. The outcome was good on 88.9% and 83.3% of the patients after respectively one and six months. These results illustrate the interest of pneumatic dilatation in achalasia, which have to be proposed in the first line of the treatment.

Management of unresectable malignant esophageal obstruction.

Malignant esophageal obstruction (MEO), especially with esophago-respiratory fistula (ERF), requires efforts to achieve a meaningful degree of palliation. Laser vaporization (LV) of the esophageal tumor and placement of an endoesophageal prosthesis (EEP) represents a new combination for palliation of MEO. The purpose of the present study was to evaluate the neodymium-yttrium-aluminum-garnet (Nd:Yag) laser in reopening the esophageal channel to permit both swallowing and insertion of an EEP. Twenty-three consecutive patients with MEO were evaluated, and ERF was documented by preoperative contrast study in eight patients. All 23 patients underwent laser vaporization, dilation, and surgical placement of EEP. Adequate swallowing was attained in 21 patients; one patient with an ERF experienced recurrent aspiration from failure of the EEP to occlude the fistulous tract. Operative morbidity was 17% (4/23), which included: wound infection, 2; persistence of ERF, 1; esophageal perforation, 1; and food impaction, 1. Thirty-day operative mortality was 9% (2/23). Palliation was excellent in 87% (20/23), with discharge from the hospital by the seventh postoperative day. Mean survival was 3.3 months. We conclude that laser vaporization followed by placement of an EEP represents a major advance in the palliation of MEO.

Longterm results of esophageal myotomy for achalasia.

BACKGROUND: Achalasia is a progressive, noncurable, motor disorder of the esophagus. Myotomy of the distal esophagus is the principal method of providing palliation. A major controversy is the necessity for a complementary antireflux procedure. STUDY DESIGN: Forty-two patients were studied by clinical history manometrically, roentgenographically, and endoscopically. Transabdominal Heller myotomy is the preferred approach. Nine patients had Nissen fundoplication and parietal cell vagotomy (group 1), and 16 had posterior gastropexy and parietal cell vagotomy (group II). Initially 16 of 17 patients underwent transthoracic Heller myotomy without fundoplication (group III). Twenty-five patients were followed a mean of 10 years (range 5 to 26 years). RESULTS: One postoperative death was from adult respiratory distress. Results in group I were excellent in five, good in three, and fair in one. The patient with a fair result developed a diverticulum at the myotomy site and significant reflux at 9 years. Results in group II patients were excellent in 2, good in 11, there was 1 operative death, and no followup in 1. Of the 17 patients in group III, 3 had resection of an esophageal diverticulum, and 3 had closure of esophageal perforation caused by pneumatic dilatation. Results in the 13 patients followed were excellent in 6, good in 5, and poor in 2. CONCLUSIONS: There is no statistical difference in results by chi-square analysis between transthoracic Heller myotomy without fundoplication and transabdominal Heller myotomy with parietal cell vagotomy and Nissen fundoplication or posterior gastropexy.

Manifestations of gastrointestinal disease on chest radiographs.

Diseases of the gastrointestinal tract may result in radiographic changes in the thorax. An abnormal chest radiographic finding is often the initial clue to the diagnosis of gastrointestinal disease. This article presents the commonly recognized and some unusual thoracic manifestations of significant primary esophageal diseases including achalasia, diverticula, carcinoma, duplication cysts, varices, esophageal perforation, and postoperative changes. Intraabdominal gastrointestinal processes such as pancreatitis or pseudocysts, gastric and colonic abnormalities, pneumoperitoneum, liver abnormalities, intraabdominal abscesses, and diaphragmatic hernias, which are frequently associated with intrathoracic abnormalities, are also reviewed. Awareness of changes on the chest radiograph produced by gastrointestinal disease allows prompt diagnosis and facilitates the appropriate confirmatory diagnostic study, such as esophagography or computed tomography.

Distally migrated esophageal self-expanding metal stents: wait and see or remove?

BACKGROUND: Extraction of a migrated esophageal stent may be extremely difficult with a substantial risk of complications including esophageal perforation and hemorrhage. METHODS: Retrospectively 242 patients were evaluated who underwent implantation of self-expanding metal stents (SEMS) and 13 (5.4%) were identified with distal stent migration. In all cases of stent dislocation into the stomach, extraction of the stent was not attempted and a new stent was inserted. RESULTS: Twelve patients had dysphagia. One patient underwent surgery because of stent impaction in the colon, 3 had unrecognized passage of the stent per rectum, and 9 had evidence of the stent into the stomach. Further severe complications were not observed in any patient and all stents remained into the stomach. CONCLUSION: Complications arising from migrated esophageal stents are uncommon. Further studies are warranted to determine which patients with migrated SEMS warrant stent retrieval.

Surgical treatment of severe obesity with a low-pressure adjustable gastric band: experimental data and clinical results in 625 patients.

OBJECTIVE: To evaluate the use of a low-pressure gastric band in the treatment of severe obesity in a prospective study. SUMMARY BACKGROUND DATA: Gastric banding for severe obesity has been associated with erosion and perforation of the stomach. The Swedish adjustable gastric band (SAGB) has been proposed as a low-pressure device. METHODS: From January 1998 to October 2001, 625 patients underwent laparoscopic SAGB. Median age was 36 years, and 80.4% of patients were female. Median preoperative body mass index (BMI) was 40. Previous upper abdominal surgery was reported in 36 (6%) patients. A five-trocar technique was used without a calibration balloon. RESULTS: Median follow-up was 19.5 months. All patients were treated laparoscopically with a median operating time of 80 minutes. Conversion was necessary in two patients (0.3%): one trocar injury of the mesentery and one esophageal perforation. Median hospital stay was 3 days; there were no 30-day deaths. Early morbidity was present in 27 patients (4.3%). Late band reoperation was necessary in 49 patients (7.8%). Indications for reoperation were band slippage or pouch dilation, acute total dysphagia, and band leakage or malfunction. Median excess weight loss was 45.8%, 49.9%, and 47.4% after 1, 2, and 3 years, respectively, with a measurable beneficial effect on arterial hypertension, sleep apnea syndrome, and diabetes control. CONCLUSIONS: SAGB is a safe and effective new method in the management of severe obesity. Long-term follow-up (>3 years) is necessary to confirm its effectiveness and safety.

Photodynamic therapy for dysplastic Barrett esophagus and early esophageal adenocarcinoma.

OBJECTIVE: To evaluate our results using photodynamic therapy (PDT) for the treatment of dysplasia or superficial cancer (T1 N0 M0) in patients with Barrett esophagus. PATIENTS AND METHODS: We retrospectively reviewed our clinical experience with 48 patients (34 patients with high-grade dysplasia and 14 patients with superficial cancer in Barrett esophagus) who had been referred for PDT. Initial evaluation included computed tomography and standard and high-frequency catheter endosonography. Follow-up endoscopy was performed 4 to 6 weeks after PDT with ablation of any residual glandular mucosa, using the argon plasma coagulator. Patients were then followed up indefinitely every 3 to 6 months with computed tomography, endosonography, and endoscopic surveillance. RESULTS: The median series follow-up was 18.5 months (range, 1-56 months). Apparent complete photoablation of Barrett mucosa and/or superficial neoplasm was documented in 47 of 48 cases. Complications included symptomatic strictures (11 patients), photosensitivity (7 patients), atrial fibrillation (1 patient) or recurrent congestive heart failure (1 patient), and self-limited esophageal perforation (1 patient). Failure to ablate T1 N0 M0 adenocarcinoma occurred in 1 patient. CONCLUSIONS: Porfimer sodium PDT appears to eradicate dysplastic Barrett mucosa and neoplasia. These results are promising; however, long-term studies are needed to document the efficacy of PDT in reducing the morbidity and mortality in such patients.
