    Input: HYPOTHESIS Laparoscopic anterior 90 degrees partial fundoplication for gastroesophageal reflux is associated with a lower incidence of postoperative dysphagia and other adverse effects compared with laparoscopic Nissen fundoplication . DESIGN A multicenter , prospect i ve , double-blind , r and omized controlled trial . SETTING Nine university teaching hospitals in 6 major cities in Australia and New Zeal and . PARTICIPANTS One hundred twelve patients with proven gastroesophageal reflux disease presenting for laparoscopic fundoplication were r and omized to undergo either a Nissen ( 52 patients ) or an anterior 90 degrees partial procedure ( 60 patients ) . Patients with esophageal motility disorders , patients requiring a concurrent abdominal procedure , and patients who had undergone previous antireflux surgery were excluded from this study . INTERVENTIONS Laparoscopic Nissen fundoplication with division of the short gastric vessels or laparoscopic anterior 90 degrees partial fundoplication . MAIN OUTCOME MEASURES Independent assessment of dysphagia , heartburn , and overall satisfaction 1 , 3 , and 6 months after surgery using multiple clinical grading systems . Objective measurement of esophageal manometric parameters , esophageal acid exposure , and endoscopic assessment . RESULTS Postoperative dysphagia , and wind-related adverse effects were less common after a laparoscopic anterior 90 degrees partial fundoplication . Relief of heartburn was better following laparoscopic Nissen fundoplication . Overall satisfaction was better after anterior 90 degrees partial fundoplication . Lower esophageal sphincter pressure , acid exposure , and endoscopy findings were similar for both procedures . CONCLUSIONS At the 6-month follow-up , laparoscopic anterior 90 degrees culine partial fundoplication is followed by fewer adverse effects than laparoscopic Nissen fundoplication with full fundal mobilization , and it achieves a higher rate of satisfaction with the overall outcome . However , this is offset to some extent by a greater likelihood of recurrent gastroesophageal reflux symptoms Objective To determine the influence of preoperative esophageal motility on clinical and objective outcome of the Toupet or Nissen fundoplication and to evaluate the success rate of these procedures . Summary background data Nissen fundoplication ( 360 ° ) is the st and ard operation in the surgical management of gastroesophageal reflux disease ( GERD ) . In order to avoid postoperative dysphagia it has been proposed to tailor antireflux surgery according to pre-existing esophageal motility . Postoperative dysphagia is thought to occur more commonly in patients with esophageal dysmotility and it has been recommended to use the Toupet procedure ( 270 ° ) in these patients . We performed a r and omized trial to evaluate this tailored concept and to compare the two operative techniques concerning reflux control and complication rate ( dysphagia ) . Methods 200 patients with GERD were included in a prospect i ve , r and omized study . After preoperative examinations ( clinical interview , endoscopy , 24-hour pH-metry and esophageal manometry ) 100 patients underwent either a laparoscopic Nissen procedure  ( 50 with and 50 without motility disorders ) , or Toupet ( 50 with and 50 without motility disorders ) . Postoperative follow-up after two years included clinical interview , endoscopy , 24-hour pH-metry , and esophageal manometry . Results After two years 85 % ( Nissen ) and 85 % ( Toupet ) of patients were satisfied with the operative result . Dysphagia was more frequent following a Nissen fundoplication compared to Toupet ( 19 vs. 8 , p < 0.05 ) and did not correlate with preoperative motility . Concerning reflux control the Toupet proved to be as good as the Nissen procedure . Conclusion Tailoring antireflux surgery according to the esophageal motility is not indicated , as motility disorders are not correlated with postoperative dysphagia . The Toupet procedure is the better operation as it has a lower rate of dysphagia and is as good as the Nissen fundoplication in controlling reflux Five surgical centers conducted a clinical r and omized prospect i ve trial in order to objective ly evaluate the two-year results of three anti-reflux procedures regularly performed in France :  complete ( 360 degrees ) fundoplication ( Nissen ) , posterior partial ( 180 degrees ) fundoplication ( Toupet ) and cardiophrenopexy ( Lortat-Jacob ) .  Fifty-two patients , mean age 53 years , range 28 to 74 yrs , with uncomplicated gastroesophageal reflux , as defined according to clinical , radiologic , endoscopic and pHmetry criteria , were included in this study . Twenty patients underwent a Nissen procedure , 18 had a Toupet procedure , while 14 had a Lortat-Jacob procedure . The main criterion of assessment was Minaire 's pHmetry score evaluated at two years postoperative . All three groups were well matched for clinical , radiologic , endoscopic , manometry and pHmetry findings . At two years , the number of asymptomatic patients did not statistically differ within the three groups . Four patients , however , required reoperation for invalidating recurrences : three following Lortat-Jacob 's procedure and one after Toupet 's procedure . Nissen 's and Toupet 's procedures significantly improved pHmetry scores compared with Lortat-Jacob 's procedure ; pHmetry was improved , but non significantly , by Nissen 's procedure , as compared with Toupet 's procedure . Lower sphincter pressure was significantly increased ( p less than 0.01 ) by Nissen 's procedure as compared with the two other techniques . The lower sphincter was significantly lengthened by Nissen 's and Toupet 's procedures as compared with Lortat-Jacob 's technique ( p less than 0.01 ) . The total length of esophagus was significantly increased ( p less than 0.01 ) by Nissen 's and Lortat-Jacob 's procedures in comparison with Toupet 's technique . The distance separating the lower sphincter of the esophagus and point of pressure reversal was significantly decreased ( p less than 0.05 ) by the Nissen procedure only . ( ABSTRACT TRUNCATED AT 250 WORDS BACKGROUND Total fundoplication for gastro-oesophageal reflux disease may be followed by unwanted side-effects . A r and omized trial demonstrated that an anterior 180 degrees partial fundoplication achieved effective reflux control and was associated with fewer side-effects in the short term than total fundoplication . This paper reports longer-term ( 5 year ) outcomes from that trial . METHODS Between December 1995 and June 1997 , 107 patients were r and omized to undergo either laparoscopic total fundoplication or a laparoscopic anterior 180 degrees fundoplication .  After 5 years , 101 of 103 eligible patients ( 51 total , 50 anterior ) were available for follow-up . Each patient was interviewed by a single blinded investigator and a st and ardized question naire was completed . The question naire focused on symptoms and overall satisfaction with the results of fundoplication . RESULTS There were no significant differences between the two groups with regard to control of heartburn or patient satisfaction with the overall outcome . Dysphagia , measured by a visual analogue score for solid food and a composite dysphagia score , was worse at 5 years after total fundoplication . Symptoms of bloating , inability to belch and flatulence were also more common after total fundoplication . Reoperation was required for dysphagia in three patients after total fundoplication and for recurrent reflux in three patients after anterior fundoplication . CONCLUSION Anterior 180 degrees partial fundoplication was as effective as total fundoplication for managing the symptoms of gastro-oesophageal reflux in the longer term . It was associated with a lower incidence of side-effects , although this was offset by a slightly higher risk of recurrent reflux symptoms BACKGROUND The effect of total ( Nissen ) and anterior partial fundoplication ( APF ) for the surgical treatment of gastroesophageal reflux disease ( GERD ) on the motor behavior of the esophagogastric axis has not been fully assessed . The purpose of this study was to assess any alterations in lower esophageal sphincter ( LES ) and gastric fundus motor parameters in GERD patients after Nissen or APF fundoplication .  METHODS Twenty four patients with documented GERD underwent either laparoscopic Nissen fundoplication ( n = 12 ) or laparoscopic APF ( n = 12 ) . Preoperative and postoperative stationary esophageal manometry included assessment of LES resting and postdeglutition relaxation pressures , intragastric pressure , and LES transient relaxations in the left lateral and upright positions and after gastric distension . RESULTS Both types of fundoplication result ed in significant increases in LES resting ( P < 0.001 ) and postdeglutition relaxation pressure ( P < 0.001 ) in both positions and after gastric distention . Intragastric pressure increased only after Nissen fundoplication in the postgastric distention state ( P = 0.01 ) . Transient LES relaxations were equally abolished after both procedures . All postoperative changes were to a similar level after either procedure with the exception of intragastric pressure after gastric distention , which was significantly higher after total than after partial fundoplication ( P = 0.04 ) . CONCLUSIONS Both procedures equally increase LES resting and postdeglutition relaxation pressures and abolish transient LES relaxations at all states . The significantly higher intragastric pressure at the postgastric distention state after Nissen fundoplication could possibly explain the higher incidence of epigastric fullness and discomfort after this type of antireflux surgery BACKGROUND / AIMS The authors compared the results of the Nissen fundoplication technique with the results of the Hill procedure , by using a 10-year history of patients with gastro-esophageal reflux disease . MATERIAL S AND METHODS Seventy two consecutive patients entered the study , 32 of whom underwent a 360 degrees fundoplication according to Nissen and 40 with a modified Hill operation .  In the Nissen Group , intraoperative manometry ( IOM ) was carried out in all patients ; in the Hill Group , the patients were r and omized in two sub-groups ( A and B ) , before operation ; in 20 of them ( group A ) , the procedure was r and omly associated to IOM . RESULTS The overall complications were low in both groups ( 15.6 % in the Nissen Group and 5 % in the Hill Group , p = 0.1 ) , and there was no mortality rate . The clinical results were excellent or good in 28 patients ( 87.6 % ) of the Nissen Group and in 36 patients ( 90 % ) of the Hill Group ( p = 0.5 ) ; in particular , an excellent outcome was observed in 16 patients ( 80 % ) with IOM ( sub-group A ) , while 12 patients ( 60 % ) without it ( sub-group B ) showed similar results . The manometric studies carried out six months after surgical treatment showed a decrease of the lower esophageal sphincter pressures in all patients if compared to the pressure recorded intra-operatively . In comparison to the pre-operative values , both the lower esophageal sphincter length and its intra-abdominal portion were markedly increased in the Nissen Group and in the sub-group A of the Hill patients . CONCLUSIONS These results support the conclusions that modified posterior gastropexy and 360 degrees fundoplication are effective , well tolerated , and can be properly used in the treatment of Gastro-esophageal reflux disease ( GERD ) , since both techniques showed good clinical results . A favorable clinical outcome depends mostly on adequate lower esophageal sphincter length ( LESL ) and LESIA extension , which could be more efficiently achieved by the use of intraoperative manometry ( IOM ) The efficacy of fundoplication operations in the long-term management of  gastroesophageal reflux disease ( GERD )  has been documented . However , only a few prospect i ve controlled series support the longterm ( > 10 years ) efficacy of these procedures , and further data are required to also determine whether the type of fundoplication affects the frequency of postfundoplication complaints . The aim of this study was to conduct a r and omized , controlled clinical trial to assess the long-term symptomatic outcome of a partial posterior fundoplication as compared to a total fundic wrap . During the years 1983 to 1991 , a total of 13 7 patients with chronic gastroesophageal reflux disease were enrolled in the study ; 72 were r and omized to semifundoplication ( Toupet ) and 65 to total fundoplication ( Nissen-Rossetti ) .  A st and ardized symptom question naire was used for follow-up of these patients . A total of 110 patients completed a median follow-up of 11.5 years ; 54 had a total wrap  and 56 underwent a partial posterior fundoplication . During this period , seven patients required reoperation ( Nissen-Rossetti in 5 and Toupet in 2 ) , 11 patients died , and nine patients were lost to follow-up or did not comply with the follow-up program . Control of heartburn ( no symptoms or mild , intermittent symptoms ) was achieved in 88 % and 92 % in the total and partial fundoplication groups , respectively , and the corresponding figures for control of acid regurgitation were 90 % and 94 % . We observed no difference in dysphagia scoring between the two groups , although odyn
