Does laparoscopic Nissen fundoplication lead to chronic gastrointestinal dysfunction?

Background Laparoscopic Nissen fundoplication (LNF) efficiently controls the symptoms of gastroesophageal reflux disease (GERD); however, other nonspecific gastrointestinal (GI) symptoms have been reported following LNF. The aim of this study was to evaluate the long-term effects of LNF on nonspecific GI complaints. Methods The basis for this study is the prospective follow-up of 515 patients (mean age 46 ± 13 years) who underwent a LNF between 1992 and 1998. A questionnaire was designed to evaluate GERD symptoms (i.e., heartburn, epigastric pain, regurgitation, dysphagia, and fullness, score 0–60) and nonspecific GI symptoms (i.e., vomiting, diarrhea, constipation, and lack of appetite, score 0–48). Patients were assessed before surgery, at 6 months, 2 years, and 5 years after surgery. Results Laparoscopic Nissen fundoplication was associated with a significant decrease in both GERD and nonspecific GI symptoms score at 6 months and up to 5 years, in the whole group (p < 0.001). 360 patients (69.7%) had preoperative nonspecific GI symptoms and experienced a significant reduction in these symptoms following the surgery and lasting up to 5 years. The other 155 patients (30.3%) had no preoperative GI symptoms (GI symptoms score of 0). In this group, there was a small but statistically significant increase in GI symptoms score (p < 0.001). It was, however, clinically significant (defined as a score >12) in only 9.9% of the patients. Conclusions Laparoscopic Nissen fundoplication provides an efficient treatment of GERD up to 5 years, and in a majority of patients, it is not associated with any significant increase in nonspecific GI complaints. New nonspecific bowel symptoms can develop after LNF in some patients but are unlikely to be clinically significant.

Assessment of Quality of Life after Laparoscopic Nissen Fundoplication in Patients with Gastroesophageal Reflux Disease

Background In this study two different quality of life items are compared, and correlation of patient satisfaction with preoperative and postoperative symptoms after laparoscopic Nissen fundoplication (LNF) for chronic gastroesophageal reflux disease is evaluated. Materials and Methods Between December 2002 and December 2004, 60 patients with a diagnosis of chronic gastroesophageal reflux disease scheduled for laparoscopic Nissen fundoplication were recruited prospectively and volunteered to participate in this study. Patients underwent endoscopy, and their disease-specific symptoms were scored on a scale. Quality of life was measured preoperatively and in the first and sixth postoperative months with two questionnaires: Short Form-36 (SF 36) (preoperatively) and the Gastroesophageal Reflux Disease—Health-Related Quality of Life (GERD-HRQL) (postoperatively). Results In more than 90% of the patients, typical symptoms (regurgitation and pyrozis) were controlled postoperatively (p < 0.001). In the first postoperative month, however, dysphagia (early dysphagia) was seen in 46 (76%) patients, whereas in the sixth postoperative month (late dysphagia) its incidence decreased to only 2 (3.3%) patients. Similarly, in the first postoperative month 42 (70%) patients had gas bloating, but the incidence of this symptom decreased to 26 (43.3%) patients by the sixth month (p = 0.01). The quality-of-life measurements obtained from both SF 36 and GERD-HRQL showed that quality of life of the patients improved significantly in the related domain of each item after surgery (p < 0.001). Conclusions Laparoscopic Nissen fundoplication is an effective operation that controls the typical symptoms and improves the quality of life of patients, but new-onset symptoms affect postoperative well-being. For closer evaluation of the benefits of the operation, we need new questionnaires that comprehensively evaluate the symptom spectrum of GERD both preoperatively and postoperatively.     

Effective Nissen fundoplication length and bougie diameter size in young children undergoing laparoscopic Nissen fundoplication

Background/Purpose: Laparoscopic Nissen fundoplication (LNF) is utilized in the management of symptomatic gastroesophageal reflux disease (GERD) in children. An effective length of fundoplication and bougie size has never been established in infants and children requiring LNF for GERD. To determine this effective fundoplication length and appropriate bougie size, we analyzed all patients less than 15 kg undergoing LNF for GERD over a 2-year period. Methods: Data recovered retrospectively included age, weight, gender, need for gastrostomy, length of postoperative hospitalization, operating time, bougie size, and fundoplication length. Results: One hundred patients weighed less than 15 kg (mean, 7.23 kg). Mean operating time was 95 minutes (range, 31 minutes to 159 minutes). Gastrostomies were placed in 32 patients. Postoperative hospitalization averaged 1.8 days for elective LNF. Fundoplication length was measured in each patient and averaged 2.06 cm. Bougie size varied from 22F to 42F, and the size utilized was based on the patient's weight. There were no instances of dysphagia or the need for esophageal dilatation postoperatively. Two patients have been seen for recurrent symptoms. One patient has required a second LNF, and the other has a normal upper gastrointestinal study and pH study. Conclusion: This study of LNF in small children has shown that resolution of GERD symptoms in most patients can be accomplished with an average fundoplication length of approximately 2 cm and a graduated bougie size relative to the patient's weight.     

Comparison of results from a randomized trial 1 year after laparoscopic Nissen and Toupet fundoplications

Background

The fundoplication of choice for the surgical treatment of gastroesophageal reflux disease (GERD) still is debated. Multichannel intraluminal impedance monitoring (MII) has not been used to compare objective data, and comparative subjective data on laparoscopic Nissen and Toupet fundoplications are scarce.

Methods

This study randomly allocated 125 patients with documented chronic GERD to either laparoscopic floppy Nissen fundoplication (LNF; n = 62) or laparoscopic Toupet fundoplication (LTF; n = 63). The Gastrointestinal Quality of Life Index (GIQLI), symptom grading, esophageal manometry, and MII data were documented preoperatively and 1 year after surgery. The pre- and postprocedure data were compared. Statistical significance was set at a p value lower than 0.01 (NCT01321294).

Results

Both procedures resulted in significantly improved GIQLI and GERD symptoms. Preoperative dysphagia improved in both groups, but the improvement reached significance only in the LTF group. The ability to belch was shown to be significantly more decreased after LNF than after LTF. Gas-bloat and “atypical” extraesophageal symptoms also were decreased after surgery (p < 0.01). However, bowel symptoms were virtually unchanged in both groups. Both procedures resulted in significantly improved lower esophageal sphincter pressures. The improvement was greater in the LNF group than in the LTF group (p < 0.01). The DeMeester score and the numbers of total, acid, proximal, upright, and recumbent reflux episodes decreased in both groups after surgery (p < 0.01). No significant difference between the procedures in terms of MII data was found. Six patients (4.8 %) had to undergo reoperation because of intrathoracic slipping of the wrap. All the patients had undergone LNF.

Conclusions

Both procedures proved to be equally effective in improving quality of life and GERD symptoms. However, the reoperation and dysphagia rates were lower and the ability to belch was higher after LTF than after LNF.     

On-table Endoscopy Following Laparoscopic Fundoplication

Background Laparoscopic fundoplication represents the gold standard in the surgical management of gastro-esophageal reflux disease (GERD). The achievement of long-lasting symptomatic and physiological control of reflux is the goal of therapy, as well as the minimization of troubling sequelae, in particular, dysphagia. On-table endoscopy after fundoplication was introduced in this Unit as a quality initiative in an attempt to minimize dysphagia and technical errors, and the aim of this study is to report the experience to date, and compare outcomes with the previous 100 cases performed by an experienced team. Methods Eighty patients who underwent laparoscopic Rosetti-Nissen fundoplication and on-table endoscopy (group 2) were compared with 100 consecutive prior cases (group 1). Patients were prospectively evaluated and had pre- and postoperative symptom scoring and analysis of complications (all patients), and manometry and 24-h pH testing in 120 patients (60 in each group). Results Both groups were similar with respect to demographics, esophagitis, pH score, and dysmotility. No bougie was used in either group. On-table endoscopy resulted in technical modifications in 4 (5%) patients. Early grade 2 or 3 dysphagia was evident in 4 (5%) patients in group 2, compared with 15 (15%) in group 1 (p < 0.001). Late dysphagia was evident in one patient (1.5%) in group 2 compared with 7 (7%) in group 1 (p < 0.05). Dilatation was performed in four patients (5%) in group 2, compared with 11 (11%) in group 1 (p < 0.05). Conclusions These data suggest that on-table endoscopy may be a useful quality assurance adjunct in laparoscopic anti-reflux surgery, in particular, reducing the incidence of dysphagia and reinterventions.     

Comparison of patient-centered outcomes after laparoscopic Nissen fundoplication for gastroesophageal reflux disease or paraesophageal hernia

Background Patients undergoing laparoscopic Nissen fundoplication (LNF) with paraesophageal hernias (PEH) are not only older and less healthy than those with gastroesophageal reflux disease (GERD), but in addition the repair is more complicated. We evaluated whether outcomes relating to GERD symptoms and quality of life (QOL) were impacted by the presence of PEH. Methods Prospectively entered data from 149 patients (109 GERD and 40 PEH) were evaluated prior to and one year after LNF with standardized and validated symptoms scores. Scores for heartburn, dysphagia, disease-specific QOL (GERD-HRQL), and general health-related QOL (SF-12 physical and mental component scores) were compared between patients undergoing LNF for PEH or for GERD alone, at baseline and one year after surgery. p < 0.05 was considered statistically significant. Results Preoperative data for GERD-HRQL, heartburn, and dysphagia were available for 134 patients, with 96% one-year follow-up. SF-12 data were collected for 98 patients with 100% follow-up. PEH patients were older and had greater comorbidity. Preoperative GERD-HRQL and heartburn were significantly worse in the GERD group. One year after surgery, both GERD and PEH patients showed significant improvement in GERD-HRQL, heartburn and dysphagia scores, with no difference in any of these disease or symptom measures between the two study groups. Postoperative PCS and MCS scores showed improvement in GERD patients, while PEH patient scores remained at or below the population mean. Conclusions LNF is equally effective as an antireflux procedure in both GERD and PEH patients, prevents symptoms of reflux in PEH patients that have none preoperatively, and does not increase dysphagia in either group. Despite the increased complexity of the procedure, LNF provides an effective control of reflux symptoms in patients undergoing PEH repair.

Significant weight loss after laparoscopic Nissen fundoplication

Background Laparoscopic Nissen fundoplication (LNF) has evolved as a gold standard in antireflux surgery. However, the association between body weight and gastroesophageal reflux disease (GERD) is still unclear, and no data are available concerning the effect of fundoplication on body weight. We present the first report elucidating the impact of LNF on body weight in GERD patients with special emphasis on patients quality of life.Methods From July 2000 to March 2003, LNF was carried out in 213 patients (85 women and 128 men) after thorough preoperative examination including clinical interview with standardized assessment of symptoms and quality of life (QoL), endosocopy, barium swallow, 24-h pH-metry, and manometry. Follow-up investigations were performed 3 and 12 months after LNF obtainable from 209 patients (98.1%) and 154 patients (72.3%), respectively.Results The mean body mass index (BMI) decreased significantly after LNF (27.6 ± 5.6 kg/m² before LNF vs 26.0 ± 3.8 kg/m² after LNF, p < 0.001). Twelve months after LNF, neither a tendency toward a renewed increase nor a further decrease in BMI was observable. The average body weight loss was 3.9 kg. BMI reduction was higher in women than in men (p < 0.002), and obese patients lost more weight than lean patients (p < 0.001). There was no association between BMI reduction and dysphagia. Plasma cholesterol and triglyceride levels did not change after LNF. The mean general score of the Gastrointestinal Quality of Life Index markedly improved (90.1 ± 21.3 before LNF vs 118.0 ± 16.2 after LNF, p < 0.01), as did the GERD-Health Related Quality of Life Index (21.9 ± 6.4 before LNF vs 3.5 ± 2.7 after LNF, p < 0.001). However, there was no association between changes in BMI and QoL.Conclusion LNF leads to significant and persistent body weight loss.     

Ineffective Esophageal Motility in Patients with GERD is no Contraindication for Nissen Fundoplication

Background

Patients with preoperative ineffective esophageal motility (IEM) are thought to be at increased risk for postoperative dysphagia leading to the recommendations for tailoring or avoiding anti-reflux surgery in these patients. The aim of this study was to evaluate if IEM has an influence on postoperative outcome after laparoscopic Nissen fundoplication (LNF).

Methods

Seventy-two consecutive patients with IEM underwent LNF and were case-matched with 72 patients without IEM based on sex, age, BMI, HH size, total pH percentage time, total number of reflux episodes and the presence of BE. Standardized interview assessing postoperative gastrointestinal symptoms, proton pump inhibitor intake, GERD-health-related-quality-of-life (GERD-HRQL), alimentary satisfaction and patients’ overall satisfaction was evaluated.

Results

Although a higher rate of preoperative dysphagia was observed in patients with IEM (29% IEM vs. 11% no IEM, p = 0.007), there was no significant difference in rates of dysphagia postoperatively (2 IEM vs. 1 no IEM, p = 0.559). Furthermore, no distinction was found in the postoperative outcome regarding symptom relief, quality of life, gas bloating syndrome, ability to belch and/or vomit or revision surgery between the two groups.

Conclusion

Although preoperative IEM has an influence on GERD presentation, it has no effect on postoperative outcome after LNF. IEM should not be a cause for avoiding LNF, as is has been shown as the most effective and safe anti-reflux treatment.

     

Day-case laparoscopic Nissen fundoplication

Introduction   Nissen fundoplication has been performed laparoscopically for over 15 years, being associated with shorter hospital stay and fewer complications than conventional open surgery with good long-term outcomes. Day-case laparoscopic Nissen fundoplication (LNF) is rarely performed in the UK and most series in the literature report length of stay >2 days. Methods   The objective of this study was to examine the safety and efficacy of day-case LNF. The clinical records of all patients undergoing LNF under the care of three surgeons in a district general hospital (DGH) during a 5-year period (January 2003 to December 2007) were reviewed to examine length of stay, complications, length of procedure, grade of operating surgeon and symptoms on follow-up. Results   One hundred thirteen day-case LNFs were recorded in this series. Day-case LNF patients had median age of 45 years (range 20–68 years, 65% (64.6%) male) and 98% were American Society of Anesthesiologists (ASA) grade I or II. Twenty-one cases (19%) were performed by higher surgical trainees. Median operative time was 54 minnutes (range 25–120 min). Only one perioperative complication (port-site bleed) occurred, treated without prolonging length of stay. The proportion of all LNF performed as day cases increased from 8% to 52% during the study period. Median operative time has significantly reduced from the first 20 consecutive LNF cases to the latest 20 cases [65 min (range 40–120 min) versus 48 min (range 25–72 min); p = 0.037]. At follow-up (median 7 weeks, range 2–31 weeks) 82% of patients had improvement in all presenting symptoms. Eight patients had postoperative complications [wound infection (n = 2), persistent regurgitation requiring laparoscopic division of a gastric band adhesion (n = 1), dysphagia (n = 5 with two patients requiring redo partial fundoplication and one patient requiring dilatation) and there were no conversions to open surgery. Conclusion   Day-case LNF is safe and effective for treating selected patients with gastroesophageal reflux disease (GERD) in a DGH. The proportion of day-case LNFs is increasing in our unit. Half of the LNFs in a DGH can be done as day cases. Experience is associated with a significant reduction in operative time.     

Severely disordered esophageal peristalsis is not a contraindication to laparoscopic Nissen fundoplication

Background Laparoscopic Nissen fundoplication (LNF) is the preferred operation for the control of gastroesophageal reflux disease (GERD). The use of a full fundoplication for patients with esophageal dysmotility is controversial. Although LNF is known to be superior to a partial wrap for patients with weak peristalsis, its efficacy for patients with severe dysmotility is unknown. We hypothesized that LNF is also acceptable for patients with severe esophageal dysmotility. Methods A multicenter retrospective review of consecutive patients with severe esophageal dysmotility who underwent an LNF was performed. Severe dysmotility was defined by manometry showing an esophageal amplitude of 30 mmHg or less and/or 70% or more nonperistaltic esophageal body contractions. Results In this study, 48 patients with severe esophageal dysmotility underwent LNF. All the patients presented with symptoms of GERD, and 19 (39%) had preoperative dysphagia. A total of 10 patients had impaired esophageal body contractions, whereas 32 patients had an abnormal esophageal amplitude, and 6 patients had both. The average abnormal esophageal amplitude was 24.9 ± 5.2 mmHg (range, 6.0–30 mmHg). The mean percentage of nonperistaltic esophageal body contractions was 79.4% ± 8.3% (range, 70–100%). There were no intraoperative complications and no conversions. Postoperatively, early dysphagia occurred in 35 patients (73%). Five patients were treated with esophageal dilation, which was successful in three cases. One patient required a reoperative fundoplication. Overall, persistent dysphagia was found in two patients (4.2%), including one patient with severe preoperative dysphagia, which improved postoperatively. Abnormal peristalsis and/or distal amplitude improved postoperatively in 12 (80%) of retested patients. There were no cases of Barrett’s progression to dysplasia or carcinoma. During an average follow-up period of 25.4 months (range, 1–46 months), eight patients (16%) were receiving antireflux medications, with six of these showing normal esophageal pH study results. Conclusion The LNF procedure provides low rates of reflux recurrence with little long-term postoperative dysphagia experienced by patients with severely disordered esophageal peristalsis. Effective fundoplication improved esophageal motility for most of the patients. A 360° fundoplication should not be contraindicated for patients with severe esophageal dysmotility.     

Prevalence of gastroesophageal reflux after laparoscopic Heller myotomy

Background: There is still some controversy over the need for antireflux procedures with Heller myotomy in the treatment of achalasia. This study was undertaken in an effort to clarify this question. Methods: To determine whether Heller myotomy alone would cause significant gastroesophageal reflux (GER), we studied 16 patients who had undergone laparoscopic Heller myotomy without concomitant antireflux procedures. Patients were asked to return for esophageal manometry and 24-h pH studies after giving informed consent for the Institutional Review Board (IRB)-approved study at a median follow-up time of 8.3 months (range, 3–51). Results are expressed as the mean ± SEM. Results: Fourteen of the 16 patients reported good to excellent relief of dysphagia after myotomy. They were subsequently studied with a 24-h pH probe and esophageal manometry. These 14 patients had a significant fall in lower esophageal sphincter (LES) pressure from 41.4 ± 4.2 mmHg to 14.2 ± 1.3 mmHg, after the myotomy (p < 0.01, Student's t-test). The two patients who reported more dysphagia postoperatively had LES pressures of 20 and 25 mmHg, respectively. Two of 14 patients had DeMeester scores of >22 (scores = 61.8, 29.4), while only one patient had a pathologic total time of reflux (percent time of reflux, 8%). The mean percent time of reflux in the other 13 patients was 1.9 ± 0.6% (range, 0.1–4%), and the mean DeMeester score was 11.7 ± 4.6 (range, 0.48–19.7). Conclusions: Laparoscopic Heller myotomy is effective for the relief of dysphagia in achalasia if the myotomy lowers the LES pressure to <17 mmHg. If performed without dissection of the entire esophagus, the laparoscopic Heller myotomy does not create significant GER in the postoperative period. Clearance of acid refluxate from the aperistaltic esophagus is an important component of the pathologic gastroesophageal reflux disease (GERD) seen after Heller myotomy for achalasia. Furthermore, GERD symptoms do not correlate with objective measurement of GE reflux in patients with achalasia. Objective measurement of GERD with 24 h pH probes may be indicated to identify those patients with pathologic acid reflux who need additional medical treatment.

A prospective multicenter study on laparoscopic treatment of gastroesophageal reflux disease in Italy

Background: A national survey was undertaken by the Italian Society for Laparoscopic Surgery to investigate the prevalence, indications, conversion rate, mortality, morbidity, and early results of laparoscopic antireflux surgery. Methods: Beginning on January 1, 1996, all of the centers taking part in this study were asked to complete a questionnaire on each patient. The questionnaire was divided into four parts and covered such areas as indications for surgery and preoperative workup, type of operation performed and certain aspects of the surgical technique, conversions and their causes, intraoperative and postoperative complications (within 4 weeks), and details of the postoperative course. The last part of the questionnaire focused on the follow-up period and was designed to gather data on recurrence of preoperative symptoms, postoperative symptoms (dysphagia, gas bloat), and postoperative test findings. Results: As of June 30 1998, 21 centers were taking part in the study and 621 patients were enrolled, with a median of 27 patients per center (less than one patient/month). The most popular technique was the Nissen-Rossetti (52%), followed by the Nissen (33%) and Toupet procedures (13%). Other techniques, such as the Dor and Lortat-Jacob, were used in the remainder of cases. Patients who received a Toupet procedure had a higher incidence of defective peristalsis (p < 0.05). The conversion rate to open surgery was 2.9%. The most common causes of conversion were inability to reduce the hiatus hernia or distal esophagus in the abdomen and adhesions from previous surgery. Perforation of the stomach and esophagus occurred in <1% of patients. Mortality was nil. Postoperative complications were observed in 7.3% of cases. The most common complication was acute dysphagia (19 patients), which required reoperation in 10 patients. No differences in the incidence of acute dysphagia were found for the different surgical techniques employed. Follow-up data were obtained for 319 patients (53%): 91.5% of the patients remained GERD symptom–free; severe esophagitis (grade 2–3) healed in 95% of the patients; lower esophageal sphincter (LES) manometric characteristics (pressure, abdominal length, and overall length) improved significantly after surgery (p < 0.005); and acid exposure of the distal esophagus decreased. Conclusions: Laparoscopic antireflux surgery has no mortality and a low morbidity. Symptoms and esophagitis are resolved in >90% of patients. Despite these favorable results, however, this type of surgery is not yet as widely employed in Italy as in other countries. Received: 12 February 1999/Accepted: 8 June 1999     

Efficacy and Safety of Seprafilm for Preventing Postoperative Abdominal Adhesion: Systematic Review and Meta-analysis

Background There is no clear consensus on the efficacy and safety of hyaluronate-carboxymethylcellulose membrane (Seprafilm) for preventing postoperative abdominal adhesion. This study is a meta-analysis of the available evidence. Methods A search of the MEDLINE, EMBASE, and the Cochrane Library identified eight studies that met the inclusion criteria for data extraction. Estimates of effectiveness were performed using fixed- and random-effects models. The effect was calculated as an odds ratio (OR) with 95% confidence intervals (CI) using the statistical software Review Manager Version 4.2. Level of significance was set at p < 0.05. Results Outcomes of 4203 patients were studied. The incidence of grade 0 adhesions among Seprafilm-treated patients was statistically significantly more than that observed among control group patients (OR 95%CI, 3.74–20.34; p < 0.01). There was no significant difference in the incidence of grade 1 adhesions between Seprafilm and control groups (OR 95%CI, 0.58–2.71; p = 0.56). The severity of grade 2 and grade 3 adhesions among Seprafilm-treated patients was significantly less than that observed among control group patients (OR 95%CI, 0.22–0.93; p = 0.03; OR 95%CI, 0.09–0.63; p < 0.01, respectively). The incidence of intestinal obstruction after abdominal surgery was not different between Seprafilm and control groups (OR 95%CI, 0.78–1.23; p = 0.84). Using Seprafilm significantly increased the incidence of abdominal abscesses (OR 95%CI, 1.06–2.54; p = 0.03) and anastomotic leaks (OR 95%CI, 1.18–3.50; p = 0.01). Conclusions Our systematic review and meta-analysis showed that Seprafilm could decrease abdominal adhesions after general surgery, which may benefit patients, but could not reduce postoperative intestinal obstruction. At the same time, Seprafilm did increase abdominal abscesses and anastomotic leaks.     

Laparoscopic fundoplication for dysphagia and peptic esophageal stricture

Peptic esophageal stricture with dysphagia is a late manifestation of severe gastroesophageal reflux disease (GERD). Although laparoscopic fundoplication is an effective antireflux operation, its efficacy for persons with peptic esophageal stricture and dysphagia has not been well defined. The aim of this study was to evaluate outcomes after fundoplication in this subgroup of GERD patients. Forty GERD patients with moderate, severe, or incapacitating dysphagia and peptic esophageal stricture were compared to a control group of 121 GERD patients without significant dysphagia or stricture. Reflux symptom severity was scored by each patient preoperatively and at most recent follow-up postoperatively (mean 1.5 years) using a scale ranging from 0 to 4 (0 = symptoms absent; 4 = symptoms incapacitating). Symptom scores were compared by the Wilcoxon rank-sum test. Postoperative redilation and fundoplication failure rates were also determined. At a mean follow-up of 1.5 years after fundoplication, the median dysphagia score had improved from 3 to 0 (P <0.001) in stricture patients and remained low (score 0) in the control group. The median heartburn score also improved from 3 to 0 (P <0.001) in stricture patients, with an identical response in the control group (P <0.001). Among dysphagia/stricture patients, 35 (87.5%) reported overall satisfaction and have not required secondary medical treatment or esophageal dilation. Four patients (10%) have required endoscopic redilation for residual dysphagia and one (2.5%) had re-operation for fundoplication herniation shortly after operation. Laparoscopic fundoplication is an effective therapy for patients with dysphagia and peptic esophageal stricture.

Feasibility of laparoscopic Nissen fundoplication as a day-case procedure

Background  The aim of this prospective double-cohort pilot study is to evaluate the feasibility and desirability of laparoscopic Nissen fundoplication (LNF) performed in day-care when compared with laparoscopic cholecystectomy (LC) in day-care. Methods  Patients who underwent a LNF in day-care were prospectively evaluated. LNF patients were treated according to LC in day-care protocol. Outcome parameters were EQ-5D, visual analogue scale (VAS), and patient satisfaction. Results  From October 2005 to March 2008, 22 patients underwent LNF and 48 patients LC in day-care. After LNF, 21 out of 22 (95%) patients were discharged the same day. Seven (32%) patients were seen postoperatively in the Emergency Department with dysphagia or pain and two (9%) patients were readmitted. After LC, 45 out of 48 (94%) patients were discharged the same day. Six (12.5%) patients were seen postoperatively in the Emergency Department because of wound infection or pain and three (6%) were readmitted. EQ-5D and VAS scores were significantly worse after LNF in day-care (repeated measurements, p < 0.0001 and p < 0.0001). In a telephone survey 66.7% preferred a short hospital stay over day-care surgery after LNF compared with 30.9% after LC (p = 0.011). Conclusions  LNF in day-care is feasible and safe, but postoperative pain scores are high and most prefer short hospital stay.     

Laparoscopic antireflux surgery

Background: Concern has been raised about operating on patients with gastroesophageal reflux disease (GERD) and normal lower esophageal sphincter (LES) pressure for the fear that a fundoplication may fail to control reflux and result in a high rate of postoperative dysphagia. We hypothesized that fundoplication is effective in patients with GERD irrespective of the preoperative LES pressure, and that in patients with normal LES pressure, a total fundoplication does not result in a high incidence of dysphagia. Methods: We studied 280 unselected patients with GERD who underwent laparoscopic fundoplication. They were divided in three groups based on the preoperative LES pressure (normal, 14–24 mmHg): group A (LES pressure, 0–6 mmHg; 61 patients; 22%); group B (LES pressure, 7–13 mmHg; 178 patients; 64%); group C (LES pressure, ?14 mmHg; 41 patients; 14%). De novo dysphagia was defined as new onset of postoperative dysphagia lasting more than 10 weeks. The average follow-up period was 17 ± 22 months. Results: There was no difference in resolution of symptoms among the three groups. Heartburn and regurgitation resolved or improved respectively in 96% of group A, 90% of group B, and 91% of group C patients. In addition, there was no difference in the incidence of de novo dysphagia, which occurred in 8% of group A, 7% of group B, and 2% of group C. Conclusions: We conclude that fundoplication controlled GERD irrespective of preoperative LES pressure, and that a normal LES pressure before surgery was not associated with a higher rate of postoperative dysphagia.     

Is the use of a bougie necessary for laparoscopic Nissen fundoplication?

HYPOTHESIS: Esophageal intubation with a bougie during laparoscopic Nissen fundoplication (LNF) is commonly used to prevent an excessively tight wrap. However, a bougie may cause intraoperative gastric and esophageal perforations. We hypothesized that LNF is safe and effective when performed without a bougie. DESIGN: Retrospective review of 102 consecutive patients who underwent LNF without a bougie. SETTING: Tertiary care university hospital. PATIENTS: All patients presented with symptoms of reflux disease. Mean (+/- SD) percentage of time with pH of less than 4 was 12.6% +/- 9.4%. Mean DeMeester score was 47.8. Mean (+/- SD) resting lower esophageal sphincter pressure was 15.0 +/- 9.4 mm Hg. Mean (+/- SD) distal esophageal amplitude was 69.4 +/- 39.2 mm Hg. INTERVENTION: During LNF, we obtained 2 to 3 cm of intra-abdominal esophagus, divided all short gastric vessels, reapproximated the crura, and performed a loose 360 degrees fundoplication without a bougie. MAIN OUTCOME MEASURES: Postoperative rates of dysphagia, gas bloat, and recurrent reflux. RESULTS: In the early postoperative period, 50 patients (49.0%) complained of mild, 11 (10.8%) of moderate, and 7 (6.9%) of severe dysphagia. Average (+/- SD) duration of early dysphagia was 4.6 +/- 2.1 weeks. Dysphagia resolved in 61 (89.7%) of 68 patients within 6 weeks. Late resolution of dysphagia was noted in 4 (5.8%) patients. Three patients were successfully treated with esophageal dilatations. Persistent dysphagia was found in 1 patient. Thirty patients (29.4%) had transient gas bloat. Mild persistent reflux, requiring daily medication, was noted in 5 (4.9%) patients. CONCLUSIONS: Performance of LNF without a bougie offers a safe and effective therapy for gastroesophageal reflux disease. While avoiding the potential risks for gastric and esophageal injury, it may provide low rates of long-term postoperative dysphagia and reflux recurrence.     

The use of medication after laparoscopic antireflux surgery

Background  Laparoscopic antireflux surgery (LARS) significantly improves symptoms of gastro-esophageal reflux disease (GERD) and quality of life. Nevertheless, 14–62% of patients report using antisecretory medication after surgery, although only a tiny percentage has proven recurrence of GERD. We sought to determine symptoms of GERD, quality of life, and use of medication before and after LARS, and to compare our findings with those from previous studies. Methods  Five hundred fifty-three patients with GERD who underwent LARS were evaluated before and at 1 year after surgery. After surgery, multidisciplinary follow-up care was provided for all patients by surgeons, psychologists, dieticians, and speech therapists. Results  Symptoms of GERD and quality of life improved significantly and only 4.2% of patients still required medication after surgery [proton pump inhibitors (PPI) (98.4 vs. 2.2%; p < 0.01), prokinetics (9.6 vs. 1.1%; p < 0.01), and psychiatric medication (8 vs. 1.6%; p < 0.01)]. Conclusion  LARS significantly reduced medication use at 1-year follow-up. However, these effects might be attributed, in part, to the multidisciplinary follow-up care. Further studies are therefore required to investigate which patients may benefit from multidisciplinary follow-up care and whether its selective application may reduce the need for medication after LARS.     

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 teria. It avoids potential postoperative dysphagia in patients with weak esophageal peristalsis and results in improved esophageal body function 6 months after, surgery.

Use of Endoluminal Antireflux Therapies for Obese Patients with GERD

Background  Obese patients with gastroesophageal reflux disease (GERD) refractory to medical therapy are a challenging patient population as obesity is a preoperative predictor of failure after antireflux surgery. We therefore sought to evaluate outcomes using one of two commercially available endoluminal therapies in this population. Methods  Consecutive obese patients (body mass index (BMI) > 30) with GERD (DeMeester >14.5) undergoing either Plicator (NDO) or Stretta (Curon) were identified in our single-institution prospective database. Outcomes assessed were: (1) failure rate (absolutely no symptomatic improvement after procedure and/or need for subsequent antireflux surgery), (2) postoperative vs. preoperative symptom (heartburn, chest pain, regurgitation, dysphagia, cough, hoarseness, and asthma) scores, and (3) proton-pump inhibitor (PPI) medication use. Results  Twenty-two patients each underwent an endoluminal therapy (ten Plicator patients and 12 Stretta patients) with mean follow-up of 1.5 years. There were no treatment-associated complications. Mean BMI was not different between Plicator and Stretta groups (39.6 vs. 38.6, respectively, p = 0.33). The failure rate for the entire cohort was 28% (10% Plicator vs. 42% Stretta, p = 0.11). The proportion of patients reporting moderate/severe symptoms postop was significantly less than preop: chest pain 9% vs. 13% (p = 0.04), cough 22% vs. 36% preop (p = 0.025), voice changes 9% vs. 36% preop (p = 0.012), and dysphagia 9% vs. 32% preop (p = 0.04). The proportion of patients on PPI medications postop was also less than preop (45% vs. 81%, p = 0.1) Conclusion  Endoluminal treatment can provide a safe means of improving GERD symptoms for some obese patients, though many will continue to require medication therapy also. Further work aimed at understanding optimal candidates for endoluminal therapy in this patient population is warranted.
