Peptic strictures of the esophagus are a common sequelae of long-standing reflux esophagitis. They occur in approximately 10% of patients with gastroesophageal reflux disease seeking medical evaluation. Factors predisposing to stricture formation are poorly understood; however, stricture patients are typically older, have a longer duration of reflux symptoms, and more frequently display abnormal esophageal motility than reflux patients without strictures. Diagnosis can usually be made with a careful history but should be confirmed with a barium esophagram followed by endoscopy with biopsies to exclude malignancy. Relief of dysphagia, which is the initial goal of therapy, can be readily accomplished in most patients using polyethylene or mercury-filled dilators or balloons. An equally important therapeutic objective should be the complete healing of associated esophagitis using proton pump inhibitors. Surgical treatment is reserved for the subset of patients with intractable esophagitis, irreversibly damaged esophagus, or extraesophageal manifestations.

The clinical efficacy of procaine penicillin and sulbactam-ampicillin was compared in patients with peritonsillar abscesses after peroral abscess drainage. Forty-two patients were randomly assigned to receive either procaine penicillin or sulbactam-ampicillin intramuscularly on an outpatient basis. The mean time required for clinical symptoms (throat pain, dysphagia and fever) to resolve was compared. No statistically significant difference was found between the clinical recoveries of patients using either antibiotic (P > 0.05). The authors conclude that intramuscular procaine penicillin can be safely prescribed on an outpatient basis to most patients with peritonsillar abscess after incision and drainage. In contrast, a broader spectrum and more expensive antibiotic, such as sulbactam-ampicillin, should be reserved for non-responders.

Achalasia is a primary esophageal motor disorder of unknown etiology producing complaints of dysphagia, regurgitation, and chest pain. The current treatments for achalasia involve the reduction of lower esophageal sphincter (LES) pressure resulting in improved esophageal emptying. Calcium channel blockers and nitrates, once used as initial treatment strategy for early achalasia, are now only used in patients who are not candidates for pneumatic dilation or surgery and those not responding to botulinum toxin injections. By virtue of the more rigid balloons, the current pneumatic dilators are more effective and have better efficacy than the older more compliant balloons. The graded approach to pneumatic dilation using the Rigiflex balloons (3.0, 3.5, and 4.0 cm) are now the most commonly used nonsurgical means of treating patients with achalasia, resulting in symptom improvement in up to 90% of patients. Surgical myotomy, once with high morbidity and long hospital stay, can now be performed laparoscopically with similar efficacy to the open surgical approach (94% vs. 84%, respectively), reduced morbidity, and hospitalization time. Given the advances in both balloon dilation and laparoscopic myotomy, most patients with achalasia can now choose between these two equally efficacious treatment options. Botulinum toxin injection of the LES should be reserved for patients who cannot undergo balloon dilation and are not surgical candidates.

Cervical hematomas are generally associated with trauma, surgery, and tumors. Although they are rare, they can be life-threatening because they put the patient at risk for great-vessel compression and upper airway obstruction. We describe two cases of spontaneous cervical hematoma--one in an 81-year-old man and the other in a 30-year-old woman. The man reported dysphonia, dysphagia, and neck swelling of 5 hours' duration. He had been taking 100 mg/day of aspirin for a cardiovascular condition. Examination revealed that the man had polycythemia vera. The woman was found to have neck ache, odynophagia, and cervical ecchymosis; portal hypertension, schistosomiasis, and blood dyscrasia were also found. Both patients denied trauma. A suspected diagnosis of cervical hematoma was confirmed by computed tomography, and treatment was instituted. The hematomas resolved in about 2 weeks. The treatment of cervical hematoma is controversial, although it is agreed that the evaluation of upper airway obstruction and its permeability is mandatory. Surgical treatment is generally reserved for complicated cases because of the risk of infection or bleeding.

Achalasia is an uncommon motility disorder of the esophagus with an uncertain etiology. Considerable debate exists regarding the most effective treatment for long-term relief of symptoms. For decades, pneumatic dilatation has been the primary treatment option, and surgery was reserved for patients who required repeated dilations or for those who were not willing to undergo the risk of perforation associated with dilatation. Recently botulinum toxin injection of the lower esophageal sphincter has been shown to provide substantial short-term relief from dysphagia; however, its effect only lasts for a short period of time. Recently, minimally invasive surgical techniques have been developed to perform a Heller myotomy effectively with an antireflux procedure. This has become a primary treatment option for many patients. We present a review of the outcome of different therapeutic options of achalasia with a special focus on laparoscopic procedures.

Gastroesophageal reflux disease (GERD) is a frequent illness, sometimes causing disabling symptoms and/or permanent oesophageal lesions. Etiology is multifactorial and not completely defined. Therapy is medical at first step, surgical indication is reserved to those patients with less compliance for medical therapy, unsuccessful medical therapy or reflux related complications. Different surgical techniques have been suggested for treatment of GERD, like Nissen, Rossetti or Toupet fundoplication. During the last decade laparoscopy has been proposed as a less invasive approach when surgery is indicated. From 1995 to the first months of 1999, 42 pts (28 females, 14 males, mean age 53.7 years), were operated on. Diagnosis and surgical indication were confirmed preoperatively by barium X-rays, endoscopy and 24 hrs-Ph-manometry. Hiatal hernia was demonstrated in 37 cases (88%), I or II grade esophagitis in 16 and III grade in 2; 1 patient had Barrett oesophagus. 37 pts were operated on by laparoscopic Nissen fundoplication, 5 patients had a Toupet operation. Mortality and conversion rate were 0. Complications occurred in 3 patients: 1 intraoperative pneumothorax, 1 acute cardiac ischemia in a patient with known hypertension, 1 permanent dysphagia successfully treated by endoscopic dilatation. Mean postoperative hospital stay was 6.1 days. Mean follow up was 9 months (3-48) in 100% of cases. Despite the fact that few patients were operated on by using this new less invasive approach, results are encouraging with no mortality, less morbidity and great advantages for patients.

Until recently, pneumatic dilatation and intrasphincteric injection of botulinum toxin (Botox) have been used as initial treatments for achalasia, with myotomy reserved for patients with residual dysphagia. It is unknown, however, whether these nonsurgical treatments affect the performance of a subsequent myotomy. We compared the results of laparoscopic Heller myotomy and Dor fundoplication in 44 patients with achalasia who had been treated with medications (group A, 16 patients), pneumatic dilatation (group B, 18 patients), or botulinum toxin (group C, 10 patients). The last group was further subdivided according to whether there was (C2, 4 patients) or was not (C1, 6 patients) a response to the treatment. Results for groups A, B, C1, and C2, respectively, were: anatomic planes identified at surgery (% of patients)--100%, 89%, 100%, and 25%; esophageal perforation (% of patients)--0%, 5%, 0%, and 50%; hospital stay (hrs)--26+/-8, 38+/-25, 26+/-11, and 72+/-65; and excellent/good results (% of patients)--87%, 95%, 100%, and 50%. These results show that: (1) previous pneumatic dilatation did not affect the results of myotomy; (2) in patients who did not respond to botulinum toxin, the myotomy was technically straightforward and the outcome was excellent; (3) in patients who responded to botulinum toxin, the LES muscle had become fibrotic (perforation occurred more often in this setting, and dysphagia was less predictably improved); and (4) myotomy relieved dysphagia in 91% of patients who had not been treated with botulinum toxin. These data support a strategy of reserving botulinum toxin for patients who are not candidates for pneumatic dilatation or laparoscopic Heller myotomy.

Clinical decision-making in esophageal cancer surgery is a process of balancing the risks of treatment against potential benefits, such as survival and quality of life. Various options are available for esophageal reconstruction. While these reconstructive options do not directly have an impact on cancer survival, they do affect operative morbidity and long-term quality of life. The affect of various interponats (reconstructive conduits) and routes of reconstruction on operative morbidity and foregut function is reviewed. Gastric interponats are preferred for esophageal reconstruction because of their reliable vascularity and the relative simplicity of the reconstructive operation. Colon interponats supposedly provide better long-term function as an esophageal substitute (unproven), but at the cost of increased operative complexity and morbidity. Colon interposition is therefore reserved for situations in which gastric transposition is not feasible. Both posterior and anterior mediastinal routes of gastric interponat reconstruction are acceptable (meta-analysis of randomized controlled trials). Posterior mediastinal reconstruction is usually preferred when a complete (R0) resection has been accomplished. Anterior mediastinal reconstruction may prevent secondary dysphagia after incomplete (R1, R2) resections.

Achalasia is an idiopathic neuromuscular disorder of the esophagus which is associated with absence of esophageal peristalsis and incomplete relaxation of a normal or raised lower esophageal sphincter (LES). Dysphagia is the most commonly associated symptom. Conventional therapeutic approaches are directed to reducing LES pressure and include orally-administered smooth muscle relaxants, forceful sphincter dilation with balloon dilators, and open or laparoscopic-assisted myotomy of the LES. Pharmacologic therapies have a low success rate. Forceful dilation has a perforation complication rate of 2% to 5%, and myotomies may precipitate significant gastroesophageal reflux, a complication minimized when a partial fundal wrap is employed simultaneously. In recent years, botulinum toxin, utilized widely as a striated muscle relaxant in managing blepharospasm, anal sphincter spasm, and muscle spasm complicating CVAs, and in smoothening facial wrinkles, has been extended to the management of achalasia on the basis that it impairs smooth muscle responsiveness to acetylcholine. Eighty units of Botox (botulinum toxin) are injected directly into the endoscopically (endoscopic ultrasound techniques may facilitate localization) located LES region (20 units into each of 4 quadrants). Symptom relief lasting 6 months on average is experienced in more than 65% of treated patients, and the complication rate is negligible. This therapeutic option is reserved for patients too ill to undergo any surgical procedure and is most effective when the lower esophageal region is hypertonic.
