KTP laser ablation of Barrett's esophagus after anti-reflux surgery results in long-term loss of intestinal metaplasia. Potassium-titanyl-phosphate.

BACKGROUND: Efforts to ablate Barrett's epithelium have met with mixed results. We report the long-term follow-up evaluation of the preliminary cohort of patients who underwent thermal ablation of Barrett's epithelium with the potassium-titanyl-phosphate (KTP) laser after anti-reflux surgery. METHODS: Nine patients with intestinal metaplasia (IM) of the esophagus underwent fundoplication (7 laparoscopic Nissen, 1 laparoscopic Toupet, 1 open Nissen) between May 1993 and October 1994. Three patients had an IM less than 3 cm long (33%). One year after the operation, all the patients were symptom free, had discontinued medications, and had a normal 24-h pH study. From June 1995 to February 1996, these patients underwent a median of two (range, 1-5) endoscopic procedures with directed mucosal ablation using the KTP laser. A comparative cohort of 21 patients (IM length, <3cm; 38%) treated during the same period with fundoplication alone served as a control. The patients were followed prospectively with annual or biennial endoscopy and biopsy. All the patients were contacted by mail, telephone, or clinic visit annually to determine symptomatic and quality-of-life outcome of antireflux surgery. RESULTS: The mean follow-up period was 6.8 years (range, 6-7.5 years). At this writing, the study patients are alive and well. Eight of the patients have experienced histologic loss of IM (89%) according to their last biopsy result. One patient has had regression of low-grade dysplasia to IM. The patients treated with fundoplication alone had a mean follow-up period of 5.6 years (range, 4.7-7.2 years). On the basis of the last biopsy result, 7 of 21 patients (33%) had no evidence of IM. CONCLUSIONS: A program of tailored antireflux surgery followed by thermal mucosal ablation causes a loss of IM in a majority of patients with Barrett's esophagus. This may represent a significant improvement in histologic outcome over that of treatment with fundoplication alone (p = 0.007 Fisher's exact test).

Outcomes of laparoscopic fundoplication for gastroesophageal reflux disease and paraesophageal hernia.

BACKGROUND: Laparoscopic fundoplication has become the standard for operative treatment of gastroesophageal reflux disease (GERD). METHODS: We reviewed our experience with 1,000 consecutive patients receiving laparoscopic fundoplication for GERD (n = 882) or paraesophageal hernia (n = 118) between October 1991 and July 1999. Patients with achalasia and failed fundoplication were excluded from analysis. All the patients were evaluated preoperatively by upper endoscopy, esophageal manometry, and barium swallow. After 1994, 24-h pH monitoring was performed selectively in patients with extraesophageal symptoms and/or those without erosive esophagitis. There were 490 men 510 women in this review. Their mean age was 49 years. Procedures performed were 360 degrees floppy fundoplication (n = 879), 360 degrees fundoplication without fundus mobilization (Rossetti) (n = 22), 270 degrees posterior fundoplication (n = 96), and anterior fundoplication (n = 2). Esophageal lengthening procedure (Collis gastroplasty) was performed in combination with fundoplication in 15 patients. In seven patients the treatment was converted to open fundoplication. OUTCOMES: The average length of hospitalization was 2.2 days, and 136 patients stayed longer than 2 days. Major complications occurred in 21 patients: esophageal perforation (n= 10), acute paraesophageal herniation (n = 4), splenic bleeding (n = 2), cardiac arrest (n = 1), pneumonia (n = 3), and testicular abscess (n = 1). Additional operations were required to manage the complications in 14 patients (70%): Four of these procedures were performed emergently, and 10 patients underwent reoperation between 6 h and 10 days. There were three deaths, all of which involved elderly patients with paraesophageal hernia. There were 35 late failures requiring reoperation for recurrence of GERD or development of new symptoms: The treatment of 32 patients was revised laparoscopically, and 4 patients required laparotomy. Beyond 1 year (median follow-up period, 27 months), 94% of the reviewed patients were satisfied with their surgical outcome.

Complete clinical outcomes audit. Resource requirements and validation of the instrument.

BACKGROUND: Clinically relevant surgical outcomes are usually monitored by surgeons only for new and/or high-volume procedures. Prospective outcomes audit studies are rarely done on 100% of procedures performed by a single surgeon, a surgical practice, or an institution. Therefore, we set out to determine the resource utilization and accuracy of a well-validated system at its introduction into a North American university surgical practice. METHODS: The Otago Surgical Audit, which has been validated in a wide spectrum of surgical practices in Australasia, was applied to a university practice in general and laparoscopic surgery. Data were recorded by the surgeon on the day of operation, at discharge, and during any subsequent readmission. Resource utilization was determined by timing the important steps in data acquisition and computer entry. Data accuracy was assessed by an independent chart review of 22% of all records. Case capture was audited by reviewing operating room case logs. RESULTS: Over 1 year, from October 1, 1996 to September 30, 1997, 338 procedures were performed. Data recording and coding by the surgeon required 2 min per form, or a total of 676 min (11.3 h) annually. Data entry required 2.11 min per form, or a total of 713 min (11.9 h) for the year. Eight percent of cases were returned to the surgeon for additional information. In the medical record audit, no additional mortality or readmissions were discovered, and one minor complication was recorded in the hospital record but not the outcomes audit. One complication and three operations recorded in the audit database were omitted from operating room records. Two minor procedures on the operating room log were omitted from the audit database. Operating time reported by the surgeon averaged 19 min less than recorded in the operative log. Data accuracy and coding accuracy improved significantly between the 1st month (month 4) and the 2nd month audited (month 12), (p <.01). CONCLUSIONS: It is possible to perform a 100% clinical outcome audit with the use of minimal resources. When the surgeon is involved with data acquisition and coding, the accuracy and completeness of the log may outstrip the medical record, but a learning curve of 4-6 months may be required to achieve this goal.

Laparoscopic fundoplication failures: patterns of failure and response to fundoplication revision.

OBJECTIVE: To determine rates and mechanisms of failure in 857 consecutive patients undergoing laparoscopic fundoplication for gastroesophageal reflux disease or paraesophageal hernia (1991-1998), and compare this population with 100 consecutive patients undergoing fundoplication revision (laparoscopic and open) at the authors' institution during the same period. SUMMARY BACKGROUND DATA: Gastroesophageal fundoplication performed through a laparotomy or thoracotomy has a failure rate of 9% to 30% and requires revision in most of the patients who have recurrent or new foregut symptoms. The frequency and patterns of failure of laparoscopic fundoplication have not been well studied. METHODS: All patients undergoing fundoplication revision were included in this study. Symptom severity was scored before and after surgery by patients on a 4-point scale. Evaluation of patients included esophagogastroscopy, barium swallow, esophageal motility, 24-hour ambulatory pH, and gastric emptying studies. Statistical analysis was performed with multiple chi-square analyses, Fisher exact test, and analysis of variance. RESULTS: Laparoscopic fundoplication was performed in 758 patients for gastroesophageal reflux disease and in 99 for paraesophageal hernia. Median follow-up was 2.5 years. Thirty-one patients (3.5%) have undergone revision for fundoplication failure. The mechanism of failure was transdiaphragmatic herniation of the fundoplication in 26 patients (84%). In 40 patients referred from other institutions, after laparoscopic fundoplication, only 10 (25%) had transdiaphragmatic migration (p < 0.01); a slipped or misplaced fundoplication occurred in 13 patients (32%), and a twisted fundoplication in 12 patients (30%). The failure mechanisms of open fundoplication (29 patients) followed patterns previously described. Fundoplication revision procedures were initiated laparoscopically in 65 patients, with six conversions (8%). The morbidity rate was 4% in laparoscopic procedures and 9% in open ones. There was one death, from aspiration and adult respiratory distress syndrome after open fundoplication. A year or more after revision operation, heartburn, chest pain, and dysphagia were rare or absent in 88%, 78%, and 91%, respectively, after laparoscopic revision, and were rare or absent in 91%, 83%, and 70%, respectively, after open revision, but 11 patients ultimately required additional operations for continued or recurrent symptoms, 3 after open revision (17%), and 8 after laparoscopic fundoplication (11%). CONCLUSIONS: Laparoscopic fundoplication failure is infrequent in experienced hands; the rate may be further reduced by extensive esophageal mobilization, secure diaphragmatic closure, esophageal lengthening (applied selectively), and avoidance of events leading to increased intraabdominal pressure. When revision is required, laparoscopic access may be used successfully by the laparoscopically experienced esophageal surgeon.

Asthma and gastroesophageal reflux: fundoplication decreases need for systemic corticosteroids.

An association between gastroesophageal reflux (GER) and asthma has been suggested for many decades. Although antireflux therapy (medical and surgical) has been shown to be beneficial in patients with asthma, response to therapy has not been well quantified. The aim of this study was to evaluate long-term outcome in patients with asthma and associated GER undergoing fundoplication. From a database of more than 600 patients with GER treated surgically between 1991 and 1996, 39 patients with asthma as their primary indication for surgery were identified. Asthma symptom scores were determined using the National Asthma Education Program classification, and medication frequency scores were determined preoperatively and at latest follow-up (median follow-up 2.7 years). Comparisons were made using the Wilcoxon rank-sum test. Asthma symptom scores decreased significantly after antireflux surgery. More important, the medication scores for use of systemic corticosteroids decreased significantly postoperatively (2.2 preoperatively vs. 0.7 postoperatively; P = 0.0001). Of the nine patients who required daily oral corticosteroids, seven have discontinued treatment entirely (78%). In patients with asthma associated with GER, symptoms of asthma are improved following fundoplication. Especially important has been the ability to wean patients from systemic corticosteroids postoperatively. Fundoplication should be offered to those patients with GER-associated asthma, especially those who are steroid dependent.
