Laryngeal histoplasmosis.

Histoplasma capsulatum is an endemic fungus found in moist, fertile soil; in North America, it is most prevalent in the river valleys of the central United States. Most primary infections in the immunocompetent host are asymptomatic or are thought to be a flu-like illness. Disseminated histoplasmosis most commonly occurs in immunosuppressed patients. Histoplasmosis infection involving the larynx is an extremely rare manifestation. Here, we describe the case of an immunocompetent man with symptomatic, acute pulmonary histoplasmosis with laryngeal involvement who presented with a chief complaint of hoarseness. We also review the literature of immunocompetent patients with laryngeal histoplasmosis.

Pharyngeal traumatic neuromas and traumatic neuromas with mature ganglion cells (pseudoganglioneuromas).

Over a period of 4 years, 14 cases of traumatic neuroma were detected in laryngoscopic biopsy specimens. The approximate incidence was 10% of biopsy specimens from this area. The most frequent symptoms in descending order of frequency, were hoarseness, dysphagia, choking spells, intermittent aphonia, and cough. Six (43%) of the 14 lesions contained mature ganglion cells. These lesions have not been reported in the pharyngeal region, and I suspect that in the past a few similar conditions have been diagnosed as ganglioneuromas. Because the lesion appears to be the cause of the symptoms and is a reactive, nonneoplastic process, accurate diagnosis and commensurate management are important.

Spindle cell (sarcomatoid) carcinomas of the larynx: a clinicopathologic study of 187 cases.

Laryngeal spindle cell (sarcomatoid) carcinomas are uncommon tumors, frequently misdiagnosed as reactive lesions or mesenchymal malignancies. The records of 187 patients with tumors diagnosed as laryngeal spindle cell (sarcomatoid) carcinoma were retrieved from the files of the Otorhinolaryngic Tumor Registry of the Armed Forces Institute of Pathology. There were 174 men and 13 women, 35-92 years of age (average, 65.6 years). Nearly all patients experienced hoarseness (n = 165 [88%] patients) for a mean duration of 11.0 months. Patients admitted to smoking (n = 162 [87%] patients) and/or alcohol use (n = 90 [48%] patients). Most tumors were glottic (n = 132 [71%]), T1 (n = 111 [59%]), 1 and polypoid (n = 185 [99%]), with a mean tumor size of 1.8 cm. Histologically, squamous cell carcinoma (n = 157 [84%]) was noted, ulcerated, and blended with the spindle cell component, which was most frequently arranged in a storiform pattern (n = 92 [49%] tumors). Foci of benign or malignant cartilage and/or bone (n = 13 [7%]) were noted in the spindle cell component. All patients were treated with surgery (n = 90 [48%] patients) or surgery with radiation (n = 97 [52%] patients). Recurrences developed in 85 (45%) patients. Overall, T1 glottic tumors managed by complete surgical eradication had the best outcome (mean follow-up, 7.8 years).

Chondrosarcoma of the larynx: a clinicopathologic study of 111 cases with a review of the literature.

Chondrosarcomas of the larynx are rare tumors accounting for about 0.5% of all laryngeal primary tumors. A total of 111 laryngeal chondrosarcoma cases, diagnosed between 1970 and 1997, were retrieved from the Otorhinolaryngic-Head & Neck Tumor Registry of the Armed Forces Institute of Pathology. There was a 3.6:1 male/female ratio of patients 25-91 years of age (mean, 64.4 years). Patients presented most frequently with hoarseness (n = 72 patients) present for a mean of 28.2 months. The majority of tumors involved the cricoid cartilage (n = 77) with a mean size of 3.5 cm. All tumors were invasive and malignant by radiology and/or histology (into bone within the ossified laryngeal cartilages in 52 tumors). Most tumors were low-grade lesions: grade 1 (n = 51), grade 2 (n = 54); there were six grade 3 tumors. An associated benign chondroma with (n = 41 tumors) or without ischemia (n = 24 tumors) was noted. All patients had surgery and five had radiation therapy. Wide excision or voice-sparing surgery was used in 73 patients, whereas 37 patients had a laryngectomy. Recurrences occurred in 20 (18%) patients, 10 of whom underwent salvage laryngectomy. At the last follow-up, 102 patients had no evidence of disease (alive or dead, mean 11.2 years) and five patients had evidence of disease (alive, one patient, 6.5 years; dead, four patients, mean 6.4 years). The six patients with high-grade chondrosarcoma were all without disease at the last follow-up (mean, 15.1 years). There was no difference in clinical outcome based on grade (p = 0.210), location (p = 0.078), or treatment (p = 0.607) but was worse for patients with a myxoid-type chondrosarcoma (p = 0.044). Primary laryngeal chondrosarcomas are typically low- to moderate-grade lesions involving the cricoid cartilage, frequently associated with a chondroma. They usually portend an excellent overall long-term prognosis with initial conservative voice-sparing surgery.

The intubating laryngeal mask airway with and without fiberoptic guidance.

UNLABELLED: We conducted this feasibility study using the intubating laryngeal mask airway (ILMA) and a polyvinyl chloride tracheal tube to compare success rates, hemodynamic effects, and postoperative morbidity with two methods of tracheal intubation. After ethics approval and informed consent, 90 healthy ASA physical status I or II women with normal airways were enrolled in the randomized, controlled study. After a standardized inhaled anesthesia induction protocol, tracheal intubations using ILMA with fiberoptic guidance (ILMA-FOB) and ILMA inserted blindly without fiberoptic guidance (ILMA-Blind) were compared with the control group of direct laryngoscopy (laryngoscopy group). All 90 patients were successfully ventilated. For tracheal intubation, success rates were equal in all three groups (97%). Total intubation times were longer for the ILMA-FOB group (77 s versus 48.5 s for laryngoscopy and 53.5 s for ILMA-Blind). The laryngoscopy group had a larger increase in mean arterial blood pressure to tracheal intubation. There were no differences in postoperative sore throat or hoarseness among the groups. In conclusion, success rates are equally high for tracheal intubation using ILMA-Blind and ILMA-FOB techniques in women with normal airways. IMPLICATIONS: The intubating laryngeal mask airway (ILMA) can be used as a primary airway for oxygenation and ventilation. Both methods of tracheal intubation using the ILMA were equally successful. Postoperative morbidity in the ILMA groups was similar to that in the laryngoscopy group. For women with normal airways, both the ILMA inserted blindly and the ILMA with fiberoptic guidance are suitable alternatives to laryngoscopy for tracheal intubation.

The cricoarytenoid joint capsule and its relevance to endotracheal intubation.

UNLABELLED: Impaired movement of the cricoarytenoid joint with hoarseness and immobility of the vocal ligament may occur as a consequence of endotracheal intubation. Little is known about the cricoarytenoid joint capsule and its role in intubation. We investigated the joint capsules of 48 cricoarytenoid joints by means of gross anatomy microscopy, histology, and scanning electron microscopy; 30 unfixed cadaver larynges were also subjected to attempts to simulate traumata such as those that may occur during intubation trials. The larynges were intubated with the arytenoid tip entering the lumen of the tracheal tube or extubated with the cuff of the tube only partially deflated. Subsequently, i.e., after dissecting the left and right cricoarytenoid joint from each larynx, the morphologic changes induced experimentally were analyzed by using histologic methods. The cricoarytenoid joint was found to be lined by a wide joint capsule. Unexpectedly large and intensively vascularized synovial folds projected into the joint cavity. After simulation of intubation and extubation, histologic analysis revealed injuries to the synovial folds and joint surface impressions, but no trauma or rupture of the outer joint capsule. We conclude that laxity of the joint capsule and the large synovial folds are predisposing factors for intubation trauma of the cricoarytenoid joint, potentially leading to hemarthros and finally to cricoarytenoid joint dysfunction. IMPLICATIONS: The present study illustrates by morphological investigations and intubation experiments that laxity of the joint capsule and large synovial folds are predisposing factors for intubation trauma of the cricoarytenoid joint, potentially leading to hemarthrosis and finally to cricoarytenoid joint dysfunction.

A comparison of hemodynamic changes after endotracheal intubation by using the lightwand device and the laryngoscope in normotensive and hypertensive patients.

We compared the effects of the lightwand technique on hemodynamic responses, time-to-intubation, number of attempts, and complications during tracheal intubation with those of direct-vision laryngoscopy in normotensive (LN and TN group; n = 20, respectively) and hypertensive (LH and TH group; n = 20, respectively) patients. Lightwand or laryngoscopic oral endotracheal intubation was performed after the induction of anesthesia with fentanyl and propofol and muscle relaxation with vecuronium. Systolic blood pressure, diastolic blood pressure, and heart rate were recorded, and the change from "before intubation" to "immediately after intubation" (DeltaP) in each variable was calculated. In normotensive patients, significantly larger DeltaP in systolic blood pressure was observed in the LN group than in the TN group (P < 0. 05). In hypertensive patients, there were no significant differences between the LH group and the TH group in DeltaP after intubation. The time-to-intubation and number of attempts in the lightwand groups were significantly longer and more frequent than those in the laryngoscope groups (P < 0.05). The number of patients who complained of hoarseness was larger in the lightwand groups than in the laryngoscope groups (P < 0.05). We conclude that the lightwand technique significantly attenuates hemodynamic changes after intubation in comparison with the laryngoscopic technique in normotensive patients. However, in hypertensive patients, there is no difference in hemodynamic changes between the two techniques.

Propofol without muscle relaxants for conventional or fiberoptic nasotracheal intubation: a dose-finding study.

UNLABELLED: Endotracheal intubation has been performed during the administration of propofol anesthesia without neuromuscular blockade. In this study, we determined the propofol dose required for conventional nasotracheal or for fiberoptic nasotracheal intubation of all patients. Thirty-two patients undergoing maxillofacial surgery were randomly assigned to the conventional (n = 16) or to the fiberoptic (n = 16) intubation group. In both groups, anesthesia was induced by using IV fentanyl and IV titrated propofol according to clinical need (spontaneous respiration rate, verbal response). An endotracheal tube was placed nasally in the pharynx and the vocal cords visualized by using a fiberscope inserted via the tube. In the conventional group, the larynx was visualized additionally with a laryngoscope blade (Miller). In both groups propofol was titrated until the vocal cords opened. Patients were tracheally intubated, and the propofol dose was recorded. In all patients, the trachea could be intubated without the use of muscle relaxants. Considerable interindividual differences of dose requirements were observed. The amount of propofol required in the conventional group was significantly (P < 0.0001) larger (median +/- SD: 2.74 +/- 1.59 mg/kg; range 1.95-7.07 mg/kg) than in the fiberoptic group (1.37 +/- 0.59 mg/kg; 0.72-2.86 mg/kg). Hemodynamics remained stable in all patients. Postintubational hoarseness occurred in three patients of each group. Fiberoptic nasal intubation without a muscle relaxant can be facilitated with significantly smaller and more predictable dosages of propofol than conventional nasal endotracheal intubation. The possibility of titrating the propofol dose under assisted ventilation until the vocal cords open during fiberoptic nasotracheal intubation and the better predictability of the required dose favors the fiberoptic approach. IMPLICATIONS: In this study, contrary to all preceding studies using predefined doses of propofol and opioids, we determined the minimal required propofol dose in combination with fentanyl for conventional or fiberoptic nasotracheal intubation without muscle relaxants.

Induction of anesthesia and insertion of a laryngeal mask airway in the prone position for minor surgery.

UNLABELLED: The use of the prone position for surgery presents potential obstacles to rapid tracking of patients during ambulatory anesthesia. We describe a prospective audit of 73 patients who placed themselves in the prone position; anesthesia was induced in this position and a laryngeal mask airway (LMA) was used to maintain the airway. Additional increments of propofol were given to one patient who had laryngospasm and to nine who required deepening of anesthesia before the LMA could be inserted. Of four cases with LMA malpositioning, the LMA was adjusted easily in three, but in one patient who was edentulous, it was necessary to hold the LMA for the duration of the procedure. Manual ventilation of the lungs via the LMA was required because of arterial oxygen desaturation and hypoventilation in four patients. Blood was noted outside the nostrils in two patients, presumably caused by soft tissue trauma after insertion of the LMA, and bradycardia occurred in five patients. In the postoperative period, hoarseness and sore throat were observed in one and six patients, respectively. With experience and appropriate patient selection, it is possible to induce and maintain anesthesia using a LMA in patients in the prone position for ambulatory surgery. IMPLICATIONS: With experience and appropriate patient selection, it is possible to induce and maintain anesthesia using a laryngeal mask airway in patients in the prone position for ambulatory surgery.

Continuous intracisternal and high cervical intrathecal bupivacaine analgesia in refractory head and neck pain.

BACKGROUND: The upper cervical component of the spinomesencephalic tract and cranial nerves V, VII (nervus intermedius), IX, and X are involved in mechanisms of acute and chronic pain from head and neck structures. To date there is no reliable method for relief of refractory pain (i.e., pain that cannot be relieved by conventional pharmacologic therapies) from these structures. Therefore, we explored continuous intracisternal infusion of bupivacaine for the treatment of refractory pain of the head and neck. METHODS: Intracisternal catheters were inserted in 13 adults with refractory nonmalignant (n = 4) and malignant (n = 9) pain from the head, face, mouth, neck, and upper extremities; 0.5% plain bupivacaine was infused continuously at rates of 1-7 (median 1.5) mg/h with optional bolus doses of 0.5-2.0 mg 4-2 times/h. The efficacy was assessed from pain relief (daily VAS(max), VAS(min), and VAS(mean) scores 0-10), daily doses of intracisternal bupivacaine and total opioid (expressed as mg parenteral morphine-eq), amount of nocturnal sleep, and rates of adverse effects. RESULTS: The 13 patients were treated for 3-182 days (median 37, total 712 days), 3 patients being treated at home for 10-112 days (median 88, total 210 days). In one patient, the efficacy of the treatment could not be estimated because of advanced senility. Eleven of the remaining 12 patients obtained acceptable pain relief with daily doses of intracisternal bupivacaine ranging from 20 to 118 mg (median 37 mg): VAS(mean) scores decreased from 7 to 2, mean pain relief increased for 30% to 80%, total opioid daily dose decreased from 53 to 36 mg parenteral morphine-eq, and nocturnal sleep increased from 2 to >6h (all figures are median values). Speech, eating, walking, and natural functions were generally not affected. Side effects such as tiredness and malaise, somnolence and sleep, feeling of coldness in the neck and skull base, transient post-spinal puncture headache, paresthesias, hoarseness, dysphagia, transient paresis of the upper/lower extremities, episodic miosis and conjunctival hyperemia, and transient orthostatic arterial hypotension were each observed in one or two patients. No patient presented clinical evidence of phrenic nerve paralysis. There was no nausea or vomiting. No persistent neurologic deficit or death could be attributed to the intracisternal pain treatment. CONCLUSIONS: Continuous intracisternal infusion of bupivacaine may be a useful method in exceptional, well selected patients with refractory pain from the head and neck structures. Further studies are necessary to establish the indications and the safety of the method.

Fiberoptic intubation using anesthetized, paralyzed, apneic patients. Results of a resident training program.

BACKGROUND: There is no consensus about the best way to teach fiberoptic intubation. This study assesses the effectiveness of a training program in which novice anesthetic residents routinely were taught fiberoptic tracheal intubation of anesthetized, paralyzed, apneic patients. METHODS: Eight inexperienced anesthetic residents learned fiberoptic and conventional tracheal intubation simultaneously during their first 4 months of training. All intubations were performed using general anesthesia and muscle paralysis. Of these intubations, 223 (23%) were fiberoptic and 743 (77%) were laryngoscopic. Subsequently, their intubation skills with the two techniques were studied in a prospective, single-blind randomized trial involving 131 elective patients. Intubation times, SpO2, ETCO2, hemodynamic changes on intubation, and complications were recorded for 71 fiberoptic and 57 laryngoscopic intubations. RESULTS: There were two failures of the rigid and one failure of the fiberoptic technique due to inability to intubate within 180 s. In cases of failure, the tracheas were intubated successfully after mask ventilation by the alterative technique. No hypoxemia or hypercarbia occurred in any patient. There were no differences in hemodynamic indexes nor incidence of sore throat or hoarseness between the two groups. Mean intubation times were 56 +/- 24 s (mean +/- SD) for fiberoptic and 34 +/- 10 s (mean +/- SD) for laryngoscopic (P < 0.001). CONCLUSIONS: Novices taught fiberoptic intubation and rigid laryngoscopic intubation under similar conditions, with similar volumes of experience, learn both techniques well. The safety and effectiveness of this training regimen commend it for inclusion in any residency program.

New insights into the pathomechanism of postintubation arytenoid subluxation.

BACKGROUND: Impaired movement of the cricoarytenoid joint with hoarseness and immobility of the vocal ligament can occur as a consequence of endotracheal intubation. The biomechanics and pathomechanism of cricoarytenoid subluxation have not been demonstrated to date. METHODS: The present study attempts to simulate the trauma that has been associated with arytenoid cartilage subluxation in intubation trials on 37 unfixed larynges in cadavers from persons aged 25 to 89 years. Larynges were intubated or extubated according to former conceptions of arytenoid subluxation, which assume that the arytenoid tip enters the lumen of the tracheal tube, or that a deflection of the arytenoid occurs during withdrawal of the endotracheal tube with the cuff of the tube only partially deflated. Also, manual attempts were carried out to subluxate the arytenoid cartilage. Subsequently after dissecting the left and right cricoarytenoid joint from each larynx, the morphologic changes induced experimentally were analyzed using gross microscopic and histologic methods. RESULTS: Within the scope of the experiment, it proved impossible to produce any subluxation of a cricoarytenoid joint. Histologic analysis revealed injuries of synovial folds, joint-surface impressions of the articular cartilage, and fractures in the area of the subchondral bone in some joints. CONCLUSIONS: Based on the morphologic results, it was concluded that intubation trauma of the cricoarytenoid joint does not cause subluxation per se, but rather that formation of a hemarthros or fractures of the joint bodies lead to fixation of the joint surfaces in an abnormal position. Subsequent ankylosis may occur.

Efficiency of a new fiberoptic stylet scope in tracheal intubation.

BACKGROUND: Failed or difficult tracheal intubation is an important cause of morbidity and mortality during anesthesia. Although a number of fiberoptic devices are available to circumvent this problem, many do not allow manual control of the flexion of the tip and necessitate time-consuming preparation, special training, or the use of an external light source. To improve these limitations, the authors designed a new fiberoptic stylet scope (FSS) that has a simple form of a standard stylet with the fiberoptic view and maneuverability of its tip. This study was undertaken to prospectively evaluate the effectiveness of the FSS in tracheal intubation. METHODS: Thirty-two patients undergoing general surgery participated in this study. The authors used a standard laryngoscope only to elevate the tongue, then tracheal intubation was attempted with the glottic opening being viewed only through the FSS. The success rate, time necessary for intubation, hemodynamics, and adverse effects were recorded. RESULTS: The success rate of tracheal intubation on the first attempt using the FSS was 94% (30 of 32 patients), and the remaining two patients were intubated successfully on the second attempt. The mean time necessary for the intubation procedure was 29+/-14 s in all patients (mean +/- SD). Changes in hemodynamics during intubation were well within acceptable ranges. There were no major adverse effects, but minor sore throat (28%) and minor hoarseness (25%) on the first postoperative day. CONCLUSIONS: Tracheal intubation using the FSS proved to be a simple and effective technique for airway management.

Intracuff pressure and tracheal morbidity: influence of filling with saline during nitrous oxide anesthesia.

BACKGROUND: Diffusion of nitrous oxide into the cuff of the endotracheal tube results in an increase in cuff pressure. Excessive endotracheal tube cuff pressure may impair tracheal mucosal perfusion and cause tracheal damage and sore throat. Filling the cuff of the endotracheal tube with saline instead of air prevents the increase in cuff pressure due to nitrous oxide diffusion. This method was used to test whether tracheal morbidity is related to excess in tracheal cuff pressure during balanced anesthesia. METHODS: Fifty patients with American Society of Anesthesiologists physical status I or II were randomly allocated to two groups with endotracheal tube cuffs initially inflated to 20-30 cm H(2)O with either air (group A) or saline (group S). Anesthesia was maintained with isoflurane and nitrous oxide. At the time of extubation, a fiberoptic examination of the trachea was performed by an independent observer, and abnormalities of tracheal mucosa at the level of the cuff contact area were scored. Patients assessed their symptoms (sore throat, dysphagia, and hoarseness) at the time of discharge from the postanesthesia care unit and 24 h after extubation on a 101-point numerical rating scale. RESULTS: Cuff pressure increased gradually during anesthesia in group A but remained stable in group S. The incidence of sore throat was greater in group A than in group S in the postanesthesia care unit (76 vs. 20%) and 24 h after extubation (42 vs. 12%; P < 0.05). Tracheal lesions at time of extubation were seen in all patients of group A and in eight patients (32%) of group S (P < 0.05). CONCLUSION: Excess in endotracheal tube cuff pressure during balanced anesthesia due to nitrous oxide diffusion into this closed gas space causes sore throat that is related to tracheal mucosal erosion.

Vocal cord paralysis and reoperative parathyroidectomy. A prospective study.

One hundred sixty-three patients undergoing reoperative parathyroidectomy were evaluated before and after operation to determine the incidence of, risk factors for, and morbidity of vocal cord paralysis. These patients were compared to 77 patients undergoing initial parathyroid operation, only one of whom had vocal cord paralysis on postoperative indirect laryngoscopy (1.3%). Preoperative examination of the reoperative patients revealed vocal cord paralysis from initial exploration in 11 patients who were excluded from this study. After re-exploration, 10 patients (6.6%) had vocal cord paralysis, eight unilateral and two bilateral. Right vocal cords were paralyzed twice as often as left. In 90%, vocal cord paralysis was associated with removal or biopsy of an ipsilateral gland. Vocal cord paralysis occurred despite intraoperative visualization of the recurrent laryngeal nerves. Preoperative localization, parathyroid gland pathology, and concomitant thyroidectomy were not associated with increased risk of vocal cord paralysis. Hoarseness was the major symptom. Tracheostomy was required for two patients, one was permanent. One patient was treated for aspiration with a temporary gastrostomy. Nine of 10 patients had return of normal voice quality in an average of 4 months time. On examination 4 years or more after surgery, two of five patients had normal vocal cord motion. The oblique anatomic course of the right recurrent laryngeal nerve may account for the greater frequency of right vocal cord paralysis.

Recurrent carotid artery stenosis. Resection with autogenous vein replacement.

Recurrent carotid artery stenosis (RCAS) occurs in 10% to 15% of patients following carotid endarterectomy (CEA). A recurrent stenosis may occur as early as 6 months and will become symptomatic in 3% to 5% of patients. Early stenosis is myointimal hyperplasia, but with the passage of time may progress to the characteristic atherosclerotic lesion. Improvements in noninvasive testing allows for evaluation and early detection of restenosis. Since 1974 we have performed 3711 CEAs in 2909 patients. One hundred and six second or third CEAs were performed in 98 patients (3.5%). In 20 of these reoperations, the common carotid (CCA) and internal carotid artery (ICA) were resected and replaced by autogenous vein, usually saphenous. One of these patients had 3 previous CEAs while 7 patients had 2 and 12 patients had 1 previous operation. There were no deaths; thrombosis of one vein interposition requiring replacement occurred. Hoarseness and hypoglossal nerve palsy occurred in one patient. Follow-up ranged to 5 years with a mean of 2.8 years. Although a second CEA is possible, there are inherent technical difficulties that may be encountered and vein interposition will solve these as well as offer the potential to prevent a further recurrence.

The results of esophagogastrectomy without thoracotomy for adenocarcinoma of the esophagogastric junction.

Between 1980 and 1988, 98 patients with adenocarcinoma of the esophagogastric junction were seen at the University of Western Ontario. Eighty-two patients underwent resection of the celiac lymph nodes, lesser curve and cardia of the stomach, and thoracic esophagus through abdominal and neck incisions avoiding thoracotomy. The esophagus was replaced by a stomach tube in 80 patients or by a colon tube in two patients. Two of 82 patients died while hospitalized. Early postoperative morbidity included anastomotic leaks that closed spontaneously (13), transient hoarseness (10), myocardial infarction (2), pulmonary embolus (6), and atelectasis or pneumonia (13). Late postoperative complications included delayed gastric emptying (4), symptomatic reflux (4), diarrhea (10), and anastomotic strictures (17). The 2-year survival of 30% was significantly affected by the stage of disease (p = 0.003), depth of tumor penetration (p = 0.02), lymph node metastasis (p = 0.001), tumor differentiation (p = 0.008), and tumor DNA ploidy (p = 0.02). Local recurrences appeared initially in 20 patients: anastomotic (3), peritoneal (14), mediastinal (3); distant metastasis occurred in 27 patients: bone (15), liver (5), brain (2), and multiple organs (5). Swallowing was restored and maintained in 75 patients. Esophagogastrectomy without thoracotomy provides a safe, effective method of restoring swallowing in patients with adenocarcinoma of the esophagogastric junction. This technique provides acceptable survival and local recurrence rates.

A physiologic approach to laparoscopic fundoplication for gastroesophageal reflux disease.

OBJECTIVE: The authors examined indications, evaluations, and outcomes after laparoscopic fundoplication in patients with gastroesophageal reflux through this single-institution study. SUMMARY OF BACKGROUND DATA: Laparoscopic fundoplication has been performed for less than 5 years, yet the early and intermediate results suggest that this operation is safe and equivalent in efficacy to open techniques of antireflux surgery. METHODS: Over a 4-year period, 300 patients underwent laparoscopic Nissen fundoplication (252) or laparoscopic Toupet fundoplication (48) for gastroesophageal reflux refractory to medical therapy or requiring daily therapy with omeprazole or high-dose H2 antagonists. Preoperative evaluation included symptom assessment, esophagogastroduodenoscopy, 24-hour pH evaluation, and esophageal motility study. Physiologic follow-up included 24-hour pH study and esophageal motility study performed 6 weeks and 1 to 3 years after operation. RESULTS: The most frequent indication for surgery was the presence of residual typical and atypical gastroesophageal reflux symptoms (64%) despite standard doses of proton pump inhibitors. At preoperative evaluation, 51% of patients had erosive esophagitis, stricture, or Barrett's metaplasia. Ninety-eight percent of patients had an abnormal 24-hour pH study. Seventeen percent had impaired esophageal motility and 2% had aperistalsis. There were four conversions to open fundoplication (adhesions, three; large liver, one). Intraoperative technical difficulties occurred in 19(6%) patients and were dealt with intraoperatively in all but 1 patient (bleeding from enlarged left liver lobe). Minor complications occurred in 6% and major complications in 2%. There was no mortality. Median follow-up was 17 months. One year after operation, heartburn was absent in 93%. Four percent took occasional H2 antagonists, and 3% were back on daily therapy. Atypical reflux symptoms (e.g., asthma, hoarseness, chest pain, or cough) were eliminated or improved in 87% and no better in 13%. Overall patient satisfaction was 97%. Four patients have subsequently undergone laparotomy for repair of gastric perforation (1 year after operation), severe dumping, "slipped" Nissen, and repair of acute paraesophageal herniation. Two patients had laparoscopic revision of herniated fundoplications. Results of follow-up 24-hour pH studies were normal in 91% of patients more than 1 year after operation. In patients with poor esophageal motility, esophageal body pressure improved 1 year after operation in 75% and worsened in 10%. CONCLUSIONS: Although long-term efficacy data are lacking, intermediate follow-up shows laparoscopic fundoplication to be safe and effective. A physiologic approach to evaluation and follow-up of patients with gastroesophageal disease allows the surgeon to tailor antireflux surgery to esophageal body function and follow the function of the fundoplication and esophagus after operation.
