Nissen fundoplication for reflux esophagitis. Long-term clinical and endoscopic results in 109 of 127 consecutive patients

OBJECTIVE: This study evaluates the clinical and endoscopic long-term results of Nissen fundoplication in reflux esophagitis. SUMMARY BACKGROUND DATA: Nissen fundoplication has been reported to give good results in the treatment of gastroesophageal reflux with success rates up to 78-97%. Most of the previous studies on long-term results of fundoplication have, however, been based on interviews with only sporadic endoscopic examinations. METHODS: Of 127 patients consecutively treated with Nissen fundoplication for reflux esophagitis, 109 were available for follow-up after a median of 77 months. Upper gastrointestinal endoscopy was done in 105 cases, and all the patients with reflux symptoms or abnormal endoscopic observations were referred to esophageal 24-hour pH monitoring and manometry. RESULTS: No symptoms of gastroesophageal reflux were reported by 73 of the 109 patients, but dysphagia was present in 47. Endoscopy showed defective fundic wrap in 24 patients. Objective evidence of reflux was found in 24 patients (endoscopic esophagitis in 18 and pathologic 24-hour pH score without esophagitis in 6). Esophagitis was found in 14 of the 24 patients with defective wrap, but in only 4 of the 81 with infact wrap. CONCLUSIONS: Nissen fundoplication alleviated symptoms of gastroesophageal reflux and cured esophagitis in great majority of cases. The main determinant of outcome was the state of the fundic wrap.     

Evaluation of the antireflux mechanism following laparoscopic fundoplication

BACKGROUND: Laparoscopic Nissen fundoplication is an effective procedure for the treatment of gastro-oesophageal reflux disease (GORD), but the underlying motility mechanisms that explain the success of this operation remain unclear. METHODS: Twenty patients with a history of GORD underwent stationary oesophageal manometry and prolonged ambulatory pH monitoring, both before and 3 months after fundoplication. RESULTS: Eighteen patients were completely cured of reflux symptoms and stopped all antireflux medication after operation. After fundoplication there was a significant increase (P < 0.01) in median resting lower oesophageal sphincter (LOS) pressure and length. Median residual LOS pressure during swallow-induced LOS relaxation also increased significantly after operation (P < 0.01). The number of reflux episodes decreased from a median of 48 to 3 after fundoplication (P < 0.01). The time at pH less than 4 decreased from 5.7 to 0 per cent in the supine position (P < 0.01), and from 9.8 to 0.2 per cent while upright (P < 0.001). CONCLUSION: Early subjective results at 3 months following laparoscopic antireflux surgery show improved symptoms. One of the mechanisms underlying the antireflux action of fundoplication is an increase in median residual LOS pressure at the gastro-oesophageal junction. This may be a purely mechanical effect of the fundic wrap extrinsic to the LOS.     

Radiological and orthopedic abnormalities in Satoyoshi syndrome

BACKGROUND: The advent of proton-pump inhibitors, and subsequently of the laparoscopic technique, can be assumed to have influenced the use of antireflux surgery in gastro-oesophageal reflux disease. METHODS: Data on antireflux operations carried out in Finland in 1988-93 were obtained from national statistics, and the number of operations performed laparoscopically in 1993 was ascertained by a questionnaire to all relevant units. The rates per 100,000 population in the catchment areas were calculated. RESULTS: Antireflux surgery almost always implied fundoplication. During 1993, 784 fundoplications and 43 other antireflux procedures were performed in Finland (total population around 5 million). The fundoplication rate per 100,000 population rose from 8.8 to 15.4 between 1988 and 1993. The increase was minimal (8.1-8.2) in 1990-91 when the first proton-pump inhibitor, omeprazole, was introduced, but remarkably greater (12.8-15.4) in 1992-93, when the laparoscopic technique became popular. Differences in fundoplication rates were six to tenfold between health service districts and even larger between hospitals. CONCLUSIONS: The numbers of antireflux operations in Finland were almost static when proton-pump inhibitors were introduced, but rapidly increased after the advent of the laparoscopic technique. Remarkable discrepancies were found in the incidence of fundoplication between different areas and hospitals.     

Systemic clotting activation by low-grade endotoxaemia in liver cirrhosis: a potential role for endothelial procoagulant activation

Laparoscopic fundoplication is technically feasible in treating gastroesophageal reflux disease (GERD). Although medication is the primary treatment for GERD, not all patients respond completely or are able to adhere to a medical regimen. In the present series, 59 patients were laparoscopically treated for GERD at three centers using a standardized technique. All patients had been medically treated prior to referral, although 84 per cent had heartburn and 2 per cent had laryngitis despite 20 to 40 mg/day of omeprazole. Fifteen per cent of patients were intolerant of or would no longer take omeprazole. Patients were evaluated by esophageal manometry (in 100%) and 24-hour pH studies (in 66%). Seventy-six per cent of patients had lower-esophageal sphincter pressure <15 mm Hg. Five patients had low esophageal body peristaltic pressures (<35 mm Hg). These patients underwent Toupet partial fundoplication, whereas 54 patients underwent Nissen fundoplication. Mean operative time was 158 +/- 7 minutes, and three patients (5%) were converted to an open procedure. Operative complications were minor and occurred in 13 per cent. In 45 patients evaluated 1 year after surgery, heartburn had resolved in 98 per cent. Thirty-nine of 56 patients (70%) had mild early (<1 month postoperatively) dysphagia, and 9 (19%) had severe early dysphagia, which improved in 7 after nonoperative dilatation. Two of these had continued mild dysphagia. Two patients had severe dysphagia and were laparoscopically converted from Nissen to Toupet fundoplications, which resulted in marked improvement. Early gas bloat symptoms occurred in 45 per cent and dropped to 5 per cent at 1 year. Laparoscopic treatment of GERD is safe and effective in preventing reflux symptoms. Although mild dysphagia occurs after the procedure, this is transient in most patients. Patients with severe dysphagia can be treated with nonoperative dilatation or laparoscopic partial fundoplication and maintain the antireflux characteristics of the wrap.     

Lifetime costs of surgical versus medical treatment of severe gastro-oesophageal reflux disease in Finland

BACKGROUND: Gastro-oesophageal reflux disease (GERD) can be effectively treated pharmacologically or surgically. As GERD is often a chronic condition, we compared the long-term costs of medical and surgical management. METHODS: The medical regimens were ranitidine (150 or 300 mg/day), omeprazole (20 or 40 mg/day), and lansoprazole (30 mg/day), with costs calculated for total life expectancy after diagnosis and for one-third of that time. Costs for open or laparoscopic surgery (Nissen fundoplication) included pre- and post-operative investigations, sick leave, and calculated financial loss due to fatal outcome. RESULTS: Costs were lowest with ranitidine, 150 mg/day, for one-third of the patient's lifetime and highest with lifelong omeprazole, 40 mg/daily. The cost of open or laparoscopic operation was less than that of lifelong daily treatment with proton pump inhibitors or ranitidine, 300 mg daily. CONCLUSION: In Finland, antireflux surgery for GERD is cheaper than lifetime treatment with proton pump inhibitors.     

Study of adenovirus production in serum-free 293SF suspension culture by GFP-expression monitoring

BACKGROUND: Recently, investigators have reported the use of endoscopic myotomy in the treatment of esophageal achalasia. As with the open operation, considerable disagreement exists regarding the appropriate length of the myotomy and the need for a concomitant antireflux procedure. METHODS: Patients presenting with symptomatic achalasia between 1993 and 1997 were included in this prospective study. Preoperative studies included barium upper gastrointestinal study, endoscopy, and esophageal manometry. Laparoscopic myotomy was completed in all 20 patients; 18 had concomitant Toupet fundoplication. RESULTS: Operative times ranged from 95 to 345 minutes (mean 216). Blood loss ranged from 50 to 300 cc (mean 100 cc). There were 7 minor complications (5 mucosal injuries repaired laparoscopically, 1 bile leak and 1 splenic capsular tear). Nine patients began a liquid diet on the first day postoperatively; 19 were tolerating liquids by postoperative day 3. Hospital stay ranged from 2 to 20 days (mean 5). Eighteen patients had complete relief of dysphagia, with less than one reflux episode per month. One individual continues to have mild persistent solid food dysphagia. Another patient initially did well but subsequently developed mild recurrent dysphagia and reflux. One patient required laparoscopic take-down of the wrap because of recurrent dysphagia and now has no problems swallowing, but does complain of mild reflux. Two other patients also have mild reflux, 1 of whom did not undergo fundoplication. CONCLUSIONS: Laparoscopic Heller myotomy can be performed safely with excellent results in patients with achalasia. Adding a partial fundoplication appears to help control postoperative symptoms of reflux. This procedure should be considered the procedure of choice in patients with symptomatic esophageal achalasia.     

Clinical and manometric results of laparoscopic partial (Toupet) and complete (Rosetti-Nissen) fundoplication

It is unclear whether a partial or complete gastric fundoplication done laparoscopically will offer the best control of reflux with the fewest side effects. Prospective evaluation of laparoscopic Rosetti-Nissen (360) and Toupet (180) fundoplication was performed with assessment of clinical and manometric data. METHODS: Patients with severe gastroesophageal reflux referred for surgical correction underwent preoperative motility and upper endoscopy. A Rosetti-Nissen or Toupet fundoplication was then performed laparoscopically. Short gastrics were not divided. No bougie was used in the Toupet, which was sutured intracorporeally. A 2-cm, loose, floppy wrap about a 50-Fr bougie was performed in the Nissen. Eleven patients underwent Rosetti-Nissen and 11 Toupet fundoplication. Mean ages, duration symptoms, weight, and baseline LES, were not different. Preop esophagitis grades were similar, as were Visick Scores and presence of dysphagia. RESULTS: Visick scores at 6 months were better in the Toupet group than the Rosetti-Nissen (P = 0.07). Persistent Dysphagia in four, Gas-Bloat in two, and Odynophagia in one within the Rosetti-Nissen group accounted for the difference, and were not seen in Toupets. LES pressures differed significantly pre and postop (P < 0.001). The change in LES pressure was significantly different between Toupet and Rosetti-Nissen (chart). Seven patients had postop 24-h pH tests; all had no reflux. Three Rosettis have required revision to Toupet, with resolution of their symptoms. CONCLUSIONS: In patients with severe GERD, laparoscopic Toupet and Rosetti-Nissen control symptoms and esophageal pH similarly. LES pressures are higher postop in the Rosetti-Nissen. Dysphagia and gas-bloat are more prevalent in the Nissen group. Laparoscopic Toupet fundoplication may be superior to Rosetti-Nissen in reducing the frequency of side effects frequently associated with antireflux surgery, yet with equal control of reflux.     

Laparoscopic antireflux surgery and the thoracic surgeon: what now?

OBJECTIVE: Minimal invasive antireflux surgery is now a well accepted technique gaining a wide spread popularity. Simultaneously there is a growing tendency to fit all surgical candidates into one single type of operation, i.e. laparoscopic Nissen antireflux operation. This study evaluates the impact of this new technology on the strategy and practice of a major referral centre for antireflux surgery. METHODS: An analysis was made of indications for the different types of antireflux techniques performed between July, 1993 and 1995. If on Barium swallow the gastro-oesophageal (GO) junction proved to be reducible, a laparoscopic approach was proposed, if not, an open transthoracic access was preferred. RESULTS: One hundred and fifteen patients were operated. Fifty five patients underwent a minimal invasive approach: 49 Nissen (are the total fundoplication) and 3 Lind (are the partial fundoplication) operations through laparoscopy, 3 Belsey Mark IV through video assisted thoracic surgery (VATS). Sixty patients were treated by open surgery for following reasons: conversion to open surgery in 2 cases, redo surgery in 15 cases, previous other major abdominal surgery in 12, irreducible GO junction in 5, paraoesophageal or mixed type hernia in 12, Barrett and or oesophagitis IV in 4, combined antireflux surgery and feeding gastrostomy in 5, abdominal partial fundoplication by principle in 1, associated motility disorder in 1, combined reflux and gastric ulcer disease in 2, and severe emphysema in 1. In the laparoscopic series reflux control at 1 year post surgery as measured by 24 h pH study in 28 patients was obtained in 89.5%. One patient required a reoperation for symptomatic recurrence. CONCLUSIONS: (1) Laparoscopic antireflux surgery is a feasible and well accepted technique; (2) careful study of each individual patient is of paramount importance to choose the correct type of operation and access as well. Therefore, fitting every patient into a single type of operation, i.e. laparoscopic Nissen, should be avoided; (3) thoracic surgeons with a major interest in GO reflux disease should familiarize themselves with laparoscopic antireflux procedures.     

Failed Nissen fundoplication in two patients who had persistent vomiting and eosinophilic esophagitis

The following report describes two patients who had chronic symptoms of gastroesophageal reflux and persistent histological esophagitis, despite aggressive medical antireflux therapy, who continued to have esophagitis and remained symptomatic post antireflux surgery (Nissen fundoplication). Both patients demonstrated a severe eosinophilic esophagitis with normal gastric and duodenal histology before and after surgery. Postoperatively, each received the diagnosis of allergic enteritis and both responded clinically and histologically to oral corticosteroids and an elemental diet.     

Comprehensive 1-year cost analysis of open antireflux surgery in Nordic countries. Nordic GORD Study Group. Gastro-oesophageal reflux disease

BACKGROUND: Antireflux surgery is a highly effective treatment option in patients with severe gastro-oesophageal reflux disease. However, because of the increasing pressure of cost containment within health care, cost aspects must also be added to the decision-making process. METHODS: The aim of this analysis was to assess the total cost of open antireflux surgery during the first year after operation in 178 patients with chronic reflux, who were recruited into a controlled, prospective clinical trial. The study was carried out in 17 hospitals in the Nordic countries. RESULTS: The cost of the operation represented more than 90 per cent of the direct medical costs which amounted to approximately US $5700. For a patient in the work force the indirect cost, i.e. loss of production, represented 47 per cent of the total cost, which was about US $10800. CONCLUSION: The total cost profile of open antireflux surgery has now been established prospectively and can form a basis for future comparisons.     

Laparoscopic Toupet fundoplication for gastroesophageal reflux disease with poor esophageal body motility

Impaired esophageal body motility is a complication of chronic gastroesophageal reflux disease (GERD). In patients with this disease, a 360-degree fundoplication may result in severe postoperative dysphagia. Forty-six patients with GERD who had a weak lower esophageal sphincter pressure and a positive acid reflux score associated with impaired esophageal body peristalsis in the distal esophagus (amplitude <30 mm Hg and >10% simultaneous or interrupted waves) were selected to undergo laparoscopic Toupet fundoplication. They were compared with 16 similar patients with poor esophageal body function who underwent Nissen fundoplication. The patients who underwent Toupet fundoplication had less dysphagia than those who had the Nissen procedure (9% vs.44%; P=0.0041). Twenty-four-hour ambulatory pH monitoring and esophageal manometry were repeated in 31 Toupet patients 6 months after surgery. Percentage of time of esophageal exposure to pH <4.0, DeMeester reflux score, lower esophageal pressure, intra-abdominal length, vector volume, and distal esophageal amplitude all improved significantly after surgery. Ninety-one percent of patients were free of reflux symptoms. The laparoscopic Toupet fundoplication provides an effective antireflux barrier according to manometric, pH, and symptom criteria. It avoids potential postoperative dysphagia in patients with weak esophageal peristalsis and results in improved esophageal body function 6 months after surgery.     

On-duty medical service regulation in Norway, Sweden, Finland and Denmark

Out of hours services are under discussion in the Nordic countries, and their organisations in Norway, Sweden, Finland and Denmark are compared in the article. Only in Denmark all such services are free of charge. In Denmark and in most parts of Norway, the patient must first phone a call-in service manned by a physician who acts as receptionist cum dispatcher. House calls are very rarely made in Sweden and Finland but account for approximately 20 percent of the out of hours workload in Norway and Denmark.     

Treatment of advanced gastroesophageal reflux disease with Collis gastroplasty and Belsey partial fundoplication

OBJECTIVE: To examine the factors affecting outcome in patients with advanced gastroesophageal reflux disease. DESIGN: Retrospective analysis. SETTING: University tertiary referral center. PATIENTS: Thirty-seven patients with advanced gastroesophageal reflux disease and no previous antireflux surgery. INTERVENTIONS: Thirty patients underwent Collis gastroplasty for esophageal lengthening and Belsey partial fundoplication. Seven patients with esophageal stricture and global loss of esophageal body motility who underwent primary esophagectomy and reconstruction were used as a comparison group. OUTCOME MEASURES: Symptomatic outcome in all 37 patients was assessed by questionnaire at a median of 25 months (range, 5-156 months) after surgery. In a subset of 11 patients undergoing the Collis-Belsey procedure, outcome was measured using 24-hour pH and results of motility studies. RESULTS: The Collis-Belsey procedure was successful in relieving symptoms of gastroesophageal reflux in 21 (70%) of the 30 patients. The outcome was excellent or good in 16 (89%) of 18 patients who presented with symptoms other than dysphagia, but only in 5 (42%) of 12 patients with dysphagia (P = .01). The outcome was particularly poor if dysphagia was associated with a previously dilated esophageal stricture. Persistent or induced dysphagia was the reason for failure in all but 1 patient. Results of 24-hour esophageal pH studies were returned to normal in 8 (73%) of 11 patients undergoing postoperative evaluation. Contraction amplitudes in the distal esophagus and the prevalence of simultaneous contractions in these segments did not change after the operation. All 7 patients who underwent primary esophagectomy were classified as having an excellent or good outcome and were relieved of their reflux symptoms, including dysphagia. Six of these could eat 3 meals per day and enjoyed an unrestricted diet. CONCLUSIONS: The outcome of the Collis-Belsey procedure in patients with advanced gastroesophageal reflux disease without dysphagia is excellent. It is less so in patients with dysphagia as a preoperative symptom. Esophagectomy can provide a good outcome in patients who have a combination of dysphagia stricture and a profound loss of esophageal motility.     

Laparoscopic Nissen fundoplication for the treatment of gastroesophageal reflux disease

The Nissen fundoplication is the most common operative approach to the correction of gastroesophageal reflux disease (GERD) in the United States. This report describes our success in performing this anti-reflux procedure laparoscopically in 28 patients with symptomatic GERD refractory to conventional medical therapy. Our laparoscopic technique does not differ significantly from the traditional, open Nissen fundoplication. After surgery, all patients reported symptomatic relief, and none required medication for the control of reflux symptoms. Oral feedings were begun on the first postoperative day, and patients were typically discharged on the second day after surgery. All but two patients resumed normal eating within an average of 26 days. Two patients experienced longer term postoperative dysphagia, including one who had undergone a highly selective vagotomy concurrent with the antireflux surgery.     

Examination of contact lens surfaces by Atomic Force Microscope (AFM)

BACKGROUND: Reduction of acid secretion is an important aspect of medical treatment of reflux esophagitis. Truncal vagotomy and drainage procedures used in conjunction with antireflux procedures to reduce acid secretion in patients with gastroesophageal reflux were unsatisfactory. This study reviews the results of parietal cell vagotomy used in conjunction with a 360-degree fundoplication to determine if reduction of acid by this form of vagotomy was beneficial to patients with gastroesophageal reflux. METHODS: Between March 1973 and May 1993, 94 private and 64 Veterans Administration patients underwent parietal cell vagotomy and Nissen type fundoplication for esophageal reflux. Esophagogastroduodenoscopy (EGD), gastric analysis, cine-esophagogram, and 24-hour esophageal pH and motility studies were performed preoperatively on VA patients. Private patients underwent EGD, cine-esophagogram, and sometimes pH and motility studies. Similar studies were performed postoperatively if the patient permitted. The major technical alteration made during the study was the addition of posterior gastropexy to the operations performed between March 1978 and January 1987. Patients were considered failures if dysphagia and reflux symptoms were moderate but operation not contemplated (Visick III) or symptoms were severe and reoperation had been performed or was contemplated (Visick IV). RESULTS: There were no operative deaths. There were 25 operative failures; dysphagia contributed to failure in 4, reflux in 11, and dysphagia and reflux in 10 patients. Reoperation was required in 6 patients. There was no statistical difference in acid secretion inhibition for patients with or without postoperative reflux symptoms. The cumulative probability for operative failure was 9.3 +/- SE 4.2% for patients who underwent posterior gastropexy and 22.9 +/- SE 4.6% (P <0.02) for those who did not. CONCLUSIONS: Parietal cell vagotomy with Nissen fundoplication is a safe operation. The exposure created by PCV protected the vagi from injury. The study design made it impossible to determine whether PCV improved the results of fundoplication but the failure rate was significantly (P <0.02) reduced by the addition of posterior gastropexy. This may have lessened the risk of disintegration of the wrap that might be more likely to occur after PCV.     

Serum S-100 protein: a potentially useful prognostic marker in cutaneous melanoma

BACKGROUND: A 360 degrees or Nissen fundoplication remains controversial in patients with disordered peristalsis, some surgeons preferring a partial wrap to minimise postoperative dysphagia. AIM: To evaluate symptoms and manometric outcome in patients with disordered peristalsis after Nissen fundoplication. PATIENTS: In an initial series of 345 patients studied prospectively, 31 patients who had undergone a Nissen fundoplication had disordered peristalsis. Using preoperative manometry, patients were classified as: equivocal primary peristalsis (eight patients); abnormal primary peristalsis (four patients); abnormal maximal contraction pressure (13 patients); abnormal primary peristalsis and maximal contraction pressure (six patients). METHODS: Postoperatively, patients underwent a barium meal, oesophageal manometry and standardised clinical review by a blinded scientific officer. RESULTS: Twenty eight (90%) patients had satisfaction scores of at least 8 out of a maximum of 10 and all would undergo surgery again. Whereas 15 (48%) patients had dysphagia scores greater than 4/10 preoperatively, only two (6%) had these scores at one year. Improved peristalsis was seen in 78% of postoperative manometric studies, and mean preoperative lower oesophageal sphincter pressure increased from 6.6 (range 0-21) mm Hg to 19 (4-50) mm Hg. CONCLUSIONS: These results are similar to the overall group of 345 patients and suggest that disordered peristalsis, and possibly even absent peristalsis, is not a contraindication to Nissen fundoplication as performed in these patients.     

Esophagectomy for unsuccessful antireflux operations

BACKGROUND: Primary antireflux surgery provides excellent symptom relief in most patients. Unfortunately, the results of redo surgery are less predictable. In these patients, esophageal injury from long-standing reflux of gastric contents and operative trauma from previous failed antireflux procedures results in progressive deterioration in esophageal propulsion, poor clearance of reflux episodes, mucosal damage, and, in some cases, stricture formation. For the past 16 years, we have selectively used esophageal resection and replacement instead of another reoperation in these challenging patients. METHODS: Seventeen patients with end-stage esophageal body dysfunction and one or more previously unsuccessful antireflux procedures underwent esophagectomy and reconstruction by colon interposition in 15 patients and jejunum interposition in 2 patients. The indications for esophagectomy rather than a redo antireflux procedure were a global loss of effective esophageal motility in 13 and a nondilatable stricture in four. Their outcome was compared with that of 32 patients with adequate motility and 18 with a similar global loss of motility who had a redo antireflux procedure. Perioperative complications after esophagectomy were recorded, and long-term outcome was assessed by means of a standardized questionnaire at a median of 7 years after the operation. RESULTS: Patients with profound esophageal body dysfunction who underwent esophageal resection had outcomes similar to those with normal motility who underwent a redo antireflux procedure. Those with profound esophageal motility dysfunction who underwent a redo antireflux procedure had a worse outcome than those who underwent resection. Esophageal resection and replacement was performed without mortality or graft failure. All patients who underwent resection stated that their preoperative symptoms were relieved completely (n = 6) or improved (n = 10). Thirteen patients (81%) were able to eat three meals a day, and 12 patients (75%) enjoyed an unrestricted diet. Two thirds of the patients were at or above their ideal body weight, and 88% were fully satisfied with the outcome of the procedure. CONCLUSION: Patients with end-stage esophageal body dysfunction who have had a previous unsuccessful antireflux procedure can be treated by esophageal resection with a high expectation of success.     

Pitfalls and complications of antireflux surgery. Nissen and Collis-Nissen techniques

The outcome of total fundoplication surgery for GER disease is unsatisfactory in 15% of patients. The likelihood of an unsuccessful outcome can be reduced by careful patient selection, which includes making an accurate diagnosis, and by choosing an operation that is tailored to the patient's physiology. Intraoperative and acute postoperative complications fortunately are rare and can be avoided through the use of meticulous surgical techniques. Late complications, including dysphagia, recurrent reflux symptoms, and delayed gastric emptying, are common and have a rate of reoperation of up to 10%; a systematic evaluation usually discloses their underlying causes. A slipped fundoplication wrap, an excessively tight wrap, a paraesophageal hiatal hernia, and severe recurrent symptoms are common indications for reoperation.     

Urinary tract infections and pregnancy in women who underwent antireflux surgery in childhood

PURPOSE: For several decades ureteroneocystostomy has been performed in children to correct primary vesicoureteral reflux. A purported indication for antireflux surgery is to prevent significant upper urinary tract infection during pregnancy. We performed a long-term followup of women who underwent antireflux surgery during childhood to determine outcome in regard to urinary tract infection history and pregnancy. MATERIALS AND METHODS: We identified 227 women of childbearing age who underwent ureteral reimplantation for primary vesicoureteral reflux from 1964 through 1981. Of the 122 women contacted 41 had been pregnant (77 total pregnancies). Cystitis or asymptomatic bacteriuria and pyelonephritis developed during 18 and 5 pregnancies, respectively. The 77 pregnancies resulted in 57 term births, 7 voluntary pregnancy interruptions and 13 spontaneous abortions. RESULTS: Patients who previously underwent successful antireflux surgery continued to have a significant number of urinary tract infections through the intervening years. Despite a higher than expected incidence of pyelonephritis, they had relatively little hypertension and renal insufficiency. During pregnancy the incidence of pyelonephritis was only slightly higher than that of the general population. However, severe complications of pregnancy, such as preeclampsia, premature birth and acute renal failure, occurred more frequently in women with a history of renal scarring or hypertension (7 of 12) than in those with a history of recurrent infection alone (3 of 10). CONCLUSIONS: When renal scarring is present, reflux should be corrected before pregnancy to minimize maternal and fetal morbidity. When scarring is not present, the literature suggests that women with a history of reflux are at increased risk for pyelonephritis during pregnancy whether or not ureterocystostomy was performed. Pregnant women with a history of reflux may benefit from prophylactic antibiotics and women with reflux nephropathy should be followed throughout life.     

Should adjuvant or neoadjuvant treatment be administered in esophageal cancer?

The Nissen fundoplication is not the proper antireflux procedure for patients with poor esophageal peristalsis as it does not strengthen impaired esophageal peristalsis. The aim of this study was to investigate if tailoring of antireflux surgery according to esophageal contractility is an effective treatment of gastroesophageal reflux disease (GERD) with a low incidence of postoperative dysphagia. The Toupet fundoplication was laparoscopically performed on 32 patients with poor esophageal peristalsis and the Nissen fundoplication on 17 patients with normal peristalsis. After a median follow-up of 15 months, only 1 of the 49 patients (2.04%) complained of heartburn. Acute esophagitis was found in none of them on endoscopy. Of 40 patients tested postoperatively, 2 (5%) underwent pathologic esophageal pH monitoring. Postoperative dysphagia was found in two patients (4.1%) compared with 25 (51%) preoperatively (p < 0.05). There was a significant reduction of dysphagia following the Toupet fundoplication. Both procedures increased the resting pressure of the lower esophageal sphincter (LES) significantly, which was more pronounced following the Nissen fundoplication. Relaxation of the LES was significantly better following the Toupet than after the Nissen fundoplication. There was significant improvement of esophageal peristalsis following the Toupet fundoplication. Tailored antireflux surgery is an effective strategy for treatment of GERD. The incidence of postoperative dysphagia is low owing to improvement of impaired esophageal peristalsis following the Toupet fundoplication. It may be due to the fact that the Toupet fundoplication causes less esophageal outflow resistance than the Nissen fundoplication.
