Spinal epidural abscess after cervical pharyngoesophageal dilation.

BACKGROUND: Esophageal perforation is an uncommon but known complication of esophageal dilation. Abscess after esophageal tear is rare, especially in the spinal epidural space. This is one case report of such an abscess. METHODS: We present a case of a spinal epidural abscess after cervical pharyngoesophageal dilation. RESULTS: After surgical decompression and abscess drainage, long-term intravenous antibiotics, and physical therapy, the patient has regained some functional use of her left upper extremity. CONCLUSIONS: Early diagnosis with a gadolinium-enhanced MRI and aggressive surgical treatment are keys to successful management with a good functional outcome after this unfortunate complication.

Complications of upper gastrointestinal endoscopy and their management.

The tremendous growth in the use of gastrointestinal endoscopy has necessarily produced complications of the procedures. In general, overall reported complication rates for diagnostic endoscopy are extremely low (0.13%-0.24%) reflecting these procedures' overall safety. However, many of these reports are likely to underestimate the true complication rate. Therapeutic procedures have substantially higher complication rates, the most frequent of which is perforation. Esophageal dilation, achalasia pneumatic dilation, and esophageal endoprosthesis placement carry the highest risk of perforation, 0.25%, 3.3%, and 7% to 15%, respectively. The outcomes research movement will revolutionize the future practice of endoscopy. Practice guidelines for endoscopy will not be determined by expert panels, but will be established empirically by outcomes research. Accurate complication rates will be determined from studies with complete and timely collection of intervention, confounding factors, and outcome. Finally, risk factors will be established by studies of appropriate design and power.

Esophageal rupture after regional anesthesia: report of two cases.

Esophageal perforation after anesthesia is rare. It is usually secondary to esophageal instrumentation. Only one case of barogenic rupture after regional anesthesia has been reported. We report two additional cases and present possible mechanisms for this unusual entity. Neither patient had anatomic abnormalities by history or preoperative endoscopy. However, both patients and the previously reported patient had esophageal dysmotility resulting from advanced age, alcoholism, intraoperative medications, and preexisting disease. Each patient experienced at least one episode of emesis with subsequent perforation of the distal one third of the esophagus. The previously reported patient died; both of our patients underwent successful surgical repair and are alive 2 years later. Intraoperative or postoperative emesis in patients with esophageal dysmotility appears to be the principal factor causing esophageal rupture after regional anesthesia. Prevention of nausea and vomiting and recognition of this high-risk population may minimize this complication in the future.

Intrasphincteric botulinum toxin versus pneumatic balloon dilation for treatment of primary achalasia.

GOALS: Despite a high success rate, pneumatic dilatation for achalasia is accompanied by a significant risk of esophageal perforation. Injection of botulinum toxin (botox) into the lower esophageal sphincter (LES) can lead to improvement in symptoms with reduced risk of complications. Direct comparisons of the two techniques are needed to define their role in clinical management. STUDY: We compared pneumatic dilatation to botox for patients with achalasia using a double blind, randomized study design. Patients underwent clinical, manometric, radiographic and endoscopic evaluation to confirm primary achalasia. They were randomized to receive either 80 units of botox into the LES or Witzel balloon dilatation. Patients also received sham dilatation or injection, respectively. The patients and investigators assessing symptom response were blinded to therapy. Symptoms and esophageal function were assessed at 3 weeks, 3 months and 1 year after therapy. Treatment failure was defined as the lack of decrease in symptom grade more than 1 or recurrence of symptoms. Patients with treatment failure crossed over to the alternative treatment. RESULTS: Thirty four patients were studied, and 31 completed the trial. Of the 18 patients randomized to Witzel dilatation, 16 (89%) of 18 remained in clinical remission. Of the two patients with treatment failure, one responded to botox injection. Of the 16 patients randomized to botox, (38%) 6 of 16 remained in clinical remission. Four patients had initial failure, and 6 relapsed at a mean of 4 months after therapy. Of the nine patients who crossed over to dilatation, seven responded well, but two required surgical management of perforation. Although both treatments had excellent initial clinical improvement, patients randomized to Witzel dilatation had superior long-term success ( < 0.01). CONCLUSION: Initial therapy with Witzel dilatation is associated with better long-term outcome than a single injection of botox. Because of the risk of endoscopic perforation, botox remains a viable alternative to dilatation.

Minimal access surgery for gastroesophageal reflux: laparoscopic placement of the Angelchik prosthesis in pigs.

Conventional surgery for gastroesophageal reflux is effective but requires laparotomy. Minimal access surgery for gastroesophageal reflux could provide a decrease in morbidity. The Angelchik antireflux prosthesis is an alternative to fundoplication for the treatment of this ailment. We evaluated the results of laparoscopic placement of the Angelchik prosthesis in 10 pigs. The duration of the procedure averaged 44 min. The mean lower esophageal sphincter pressure increased from 12.2 +/- 2.8 mmHg at baseline to 45.2 +/- 7.8 (P less than 0.05), 32.1 +/- 3.9 (P less than 0.05), and 25.1 +/- 6.5 mmHg (P greater than 0.05) as measured immediately postoperatively, at 1 week, and at 3 weeks, respectively, following placement of the prosthesis. There was no instance of prosthetic migration or esophageal perforation. One postoperative death due to distention and perforation of the colon occurred. Two animals developed distal esophageal impaction of food. We conclude that the antireflux prosthesis can be safely and effectively placed using laparoscopic methods in a porcine model. Further development of this technique is warranted.

Balloon dilatation of esophageal stenosis in children.

Balloon dilatation of benign esophageal strictures is an accepted mode of therapy in adults. This report describes balloon dilatation in 20 consecutive infants and children. The lesions treated include 11 strictures at surgical anastomotic sites, seven restrictive Nissen fundoplications, and three nonanastomotic esophageal strictures. One patient had two lesions. Most dilatations were performed on an outpatient basis without anesthesia. All strictures responded immediately to dilatation. In most cases, long-term resolution occurred after three or fewer procedures. A subgroup of patients was identified in which a prolonged course of treatment was needed. These included patients with long strictures due to esophageal atresia, patients with chronic severe esophagitis, and patients with strictures at the site of esophageal perforation. No significant complications were encountered. Balloon dilatation of esophageal stenosis in children is effective and safe and should be considered before other methods of treatment are used.

Evaluation of penetrating injuries of the neck: prospective study of 223 patients.

The objective of this study was to assess the role of clinical examination, angiography, color flow Doppler imaging, and other diagnostic tests in identifying injuries to the vascular or aerodigestive structures in patients with penetrating injuries to the neck. A prospective study was made of patients with penetrating neck injuries. All patients had a careful physical examination according to a written protocol. Stable patients underwent routine four-vessel angiography and color flow Doppler imaging. Esophagography and endoscopy were performed for proximity injuries. The sensitivity, specificity, and predictive values of physical examination, color flow Doppler studies, and other diagnostic tests were assessed during the evaluation of vascular and aerodigestive tract structures in the neck. Altogether 223 patients were entered in the study. After physical examination 176 patients underwent angiography and 99 of them underwent color flow Doppler imaging. Angiographic abnormalities were seen in 34 patients for an incidence of 19.3%, but only 14 (8.0%) required treatment. Color flow Doppler imaging was performed on 99 patients with a sensitivity of 91.7%, specificity 100%, positive predictive value (PPV) 100%, and negative predictive value (NPV) 99%. These values were all 100% when only injuries requiring treatment were considered. None of the 160 patients without clinical signs of vascular injury had serious vascular trauma requiring treatment (NPV 100%), although angiography in 127 showed 11 vascular lesions not requiring treatment. "Hard" signs on clinical examination (large expanding hematomas, severe active bleeding, shock not responding to fluids, diminished radial pulse, bruit) reliably predicted major vascular trauma requiring treatment. Among 34 of the 223 total patients (15.2%) admitted with "soft" signs, 8 had angiographically detected injuries, but only one required treatment. An esophagogram was performed on 98 patients because of proximity injuries (49 patients) or suspicious clinical signs (49 patients), and two of them showed esophageal perforations. None of the 167 patients without clinical signs of esophageal trauma had an esophageal injury requiring treatment. It was concluded that physical examination is reliable for identifying those patients with penetrating injuries of the neck who require vascular or esophageal diagnostic studies. Color flow Doppler imaging is a dependable alternative to angiography. An algorithm for the initial assessment of neck injuries is suggested.

Iatrogenic esophageal-pleural fistula: subtlety of diagnosis in the absence of mediastinitis.

Seven patients with iatrogenic esophageal-pleural fistulas are described, and the differences in radiographic and physical findings in these patients and in patients with esophageal perforation with mediastinitis are emphasized. Radiographic findings in patients with esophageal pleural fistulas are pneumothorax, hydropneumothorax and localized pneumonitis. These fistulas can mimic other inflammatory supradiaphragmatic or infradiaphragmatic processes. Clinical and radiographic signs may be subtle, and active investigation is needed to establish the diagnosis of esophageal-pleural fistula in patients who have undergone esophageal manipulation.

Accidents and complications in selective and proximal gastric vagotomy.

In 3 years 266 consecutive patients were electively operated on for ulcer disease with either selective vagotomy (SV) with drainage (159) or proximal gastric vagotomy (PGV) without drainage (107). The total number of operative accidents was 15 (6 percent), similar to that of truncal vagotomy. Perforation of the stomach occurred in six SV and in one PGV. The perforation went unobserved in two patients, of whom one died. Esophageal perforations were not observed. Bleeding from the lesser omentum or from the spleen was seen in seven patients, requiring reoperation in one. Postoperative surgical complications were seen in 25 patients (9 percent): clinical gastric retention was observed in nine patients, five with SV and four with PGV, and 13 had wound abscesses or dehiscence. Fifty-nine patients had other complications, of which 52 were radiologically demonstrated atelectases, mostly without any clinical significance. The total mortality rate was 1.1 percent, similar to that of truncal vagotomy. The duration of the two operative procedures did not differ, and the greater care required for preservation of the nerve of Latarjet tended to diminish the number of operative accidents.

Resection of benign esophageal stricture through a minimally invasive endoscopic and transgastric approach.

Recurrent benign esophageal strictures that are refractory to dilation can be difficult to manage. We report a novel technique for treatment of a recurrent esophageal stricture using a minimally invasive endoscopic and transgastric approach. The patient is a 40-year-old women who developed a recurrent distal esophageal stricture after repair of an esophageal perforation. Multiple prior dilations had been unsuccessful in achieving sustained esophageal patency, and the patient presented with a complete distal obstruction demonstrated on barium esophagram. Two flexible endoscopes were used: one placed through the mouth and another through a gastrostomy. While the transilluminated lesion was visualized from below the obstruction was traversed with an endoscopic aspiration needle from above. A guidewire was placed through the needle and pulled out the gastrostomy. Both the esophageal lesion and the gastrostomy tract were then serially dilated over the wire. After dilation the residual stricture was resected using a circular stapler placed through the dilated gastrostomy tract. After this procedure the patient maintained esophageal patency with a diminished need for dilation. Details of our technique are described and the literature is reviewed.

Management of foreign body ingestion in children: experience with 42 cases.

Ingestion of foreign bodies occurs frequently in children, but there are no definite management guidelines. We reviewed 42 pediatric cases of accidental ingestion of foreign bodies with or without symptoms during the past 10 years. In decreasing order of frequency, the foreign bodies included: coins, sharp objects (needle, pin), bones (fish and chicken bone), metal object, food, seeds, plastic material, magnets, jewelry ring, and others. The majority of children were 5 years old or younger. At the time of presentation, the vast majority of objects were located in the esophagus. Sixty percent of the patients had symptoms, such as abdominal pain, vomiting and cough. Management included observation, esophagoscopy, panendoscopy, and laparotomy. Four patients (9.5%) had complications. One patient who ingested a magnet suffered from esophageal perforation with mediastinitis. Two had deep neck abscess due to esophageal penetration by bones. Another patient had hemorrhagic gastritis after swallowing a coin. All patients discharged after treatment, and none died.

Esophageal necrosis and perforation associated with the anticardiolipin antibody syndrome.

The anticardiolipin antibody syndrome has been previously associated with seven cases of gastrointestinal ischemia involving the duodenum, jejunoileum, or colon. In prior cases patients presented with gastrointestinal bleeding, abdominal pain, or an acute abdomen without gastrointestinal perforation. A patient with prior pulmonary emboli, right leg thrombophlebitis, and right popliteal artery thrombosis associated with anticardiolipin antibodies developed fatal esophageal ischemia. Postmortem examination revealed esophageal necrosis and perforation due to esophageal vascular thrombosis, as well as ischemic colitis and numerous other thromboembolic phenomena. This case report extends the gastrointestinal manifestations of the anticardiolipin antibody syndrome by describing esophageal involvement and by reporting the first case of alimentary tract perforation.

[Elective endoscopic sclerotherapy in esophageal varices].

We present our experience with elective sclerotherapy in ten years. 64 male and 57 females, median age 52.5 years, were treated. Post-necrosis cirrhosis was the primordial etiology in 44% followed by alcoholic in 40%. In regards to Child classification, 51% were "C"; 24% "B" and 25% "A". With variceal eradication we found no rebleeding, but in those without changes in variceal size, it was 82%. At six months, control of variceal hemorrhage was respectively to groups A, B, and C. 86%, 71% and 63%. The control at long follow-up were respectively 74%, 68% & 57%. Survival was directly related to the level of hepatic function instead of sclerosis. Complications were 2 to be 3% being the most severe: pleural effusion; mediastinitis and fiber. Mortality was 0.8% in one patient with esophageal perforation.

Noniatrogenic esophageal trauma.

Few guidelines are available with which to facilitate treatment in patients with noniatrogenic injuries of the esophagus. Early diagnosis and proper management are essential if a good outcome is to be expected. In an effort to define better the treatment of patients with penetrating and blunt injuries of the esophagus, we report our recent 5-year experience at an urban trauma center. From July 1988 to June 1993, nineteen patients with esophageal perforations from penetrating (18) and blunt (1) trauma were identified by our trauma registry. There was no mortality in this group of patients and morbidity was mostly due to associated injuries. Eleven cervical esophageal injuries were repaired. One cervical injury was treated by stopping oral intake and giving intravenous antibiotics. The neck was not drained in 10 of the surgical cases. In 1 patient a tracheoesophageal fistula developed, which later was repaired with a pectoralis muscle flap. Seven perforations were identified in the thoracic (2) and abdominal (5) portions of the esophagus. All were due to gunshot wounds. In 4 cases, a fundal wrap was used to reinforce the repairs. Postoperative contrast studies confirmed that all repairs were intact. We conclude that penetrating and blunt tears of the esophagus can be repaired safely with minimal mortality. Morbidity is usually from associated injuries such as to the spinal cord and trachea. When identified early, cervical esophageal injuries do not need to be drained routinely.

Argon beam plasma coagulation as therapy for high-grade dysplasia in Barrett's esophagus.

BACKGROUND & AIMS: Patients with high-grade dysplasia in Barrett's esophagus have a high chance of developing adenocarcinoma. Previously these patients have undergone resection, however, the management of patients unsuitable for surgical resection is unclear. We have studied the long-term outcome of patients who have undergone endoscopic Argon ablation for high-grade dysplasia in Barrett's. METHODS: Twenty-nine patients (median age, 64 yr; range, 43-85 yr) with high-grade dysplasia in Barrett's, who were unfit or had declined surgery, underwent Argon ablation and received follow-up evaluation over 7 years (mean follow-up, 37 mo; range, 7-78 mo). Treatment was stopped once there was no further histologic evidence of dysplasia. The patients then went on to receive a surveillance endoscopy at 3, 6, and 12 months after ablation, then annually thereafter. RESULTS: High-grade dysplasia responded to treatment in 25 patients (86%); 22 of these had complete regression to neosquamous esophageal mucosa. During follow-up evaluation, no patients died of esophageal adenocarcinoma. Four patients developed cancer, 3 of whom continue with ablation therapy. The fourth patient died of unrelated causes. A single esophageal perforation was the only significant adverse event attributable to therapy. No esophageal strictures occurred and patients returned to normal activity after 24 hours in the majority of cases. Patients who received Argon ablation showed no difference in survival to that of the general population. CONCLUSIONS: Argon beam ablation for high-grade dysplasia in Barrett's esophagus is an effective and safe treatment, especially in patients unfit for surgical resection.

[Esophageal lesions in Cushing's syndrome and corticosteroma].

The state of the esophagus was studied in 60 patients with endogenous hypercorticism (2 with corticosteroma, 58 with Icenko-Cushing disease). The purpose was to reveal the nature and frequency of esophageal lesions and peculiarities of their clinical symptoms. X-ray and endoscopic methods were used. Functional and organic esophageal changes were shown to be rather common in patients with excess of body glucocorticoids: hypomotor dyskinesia was noted in 27% of the patients, cardial insufficiency in 13%, cardial hernia of the esophageal orifice of the diaphragm in 28%, reflux-esophagitis in 43%. Cardial hernia and esophagitis in such patients are often characterized by weak clinical symptoms masked by other signs of severe endocrine pathology. They can be also symptomless making their early diagnosis difficult. However these esophageal diseases are fraught with danger and life threatening complications: ulcerations, perforations, esophageal hemorrhages aggravating a course of the main disease. These patients need appropriate therapy to avoid complications.

Multimodality treatment of esophageal disruptions.

The treatment of esophageal disruptions has changed since 1981. The value of a more selective assessment in six spontaneous ruptures and 30 mostly intrathoracic (83.4%) esophageal perforations is evaluated in this study. Based on the previous state of the esophagus, the time factor, and type and site of the disruption, reinforced primary repair (by diaphragmatic, muscular, pleural flap, or fundoplication), transhiatal closure, resection, intubation, suture combined with myotomy and fundoplication, esophageal diversion, and transhiatal mediastinal drainage were employed. The overall 30-day hospital mortality was 19.4%. Although these operations were mostly used in late (24 h to 7 months) perforations and ruptures, none of the patients with reinforced repair by autogenous diaphragmatic, muscular, or pleural flaps or fundoplication had fatal outcome for breakdown of the closure. Only patients with renal, cardiac, or multiorgan failure as a consequence of sepsis due to time elapsed before hospital admission died. The key to improve the prognosis of this life-threatening emergency is the more appropriate selection of the primary employed procedure.
