Laparoscopic vs conventional Nissen fundoplication. A prospective randomized study

"Comparison of Nissen Rossetti and Floppy Nissen techniques in laparoscopic reflux surgery"

OBJECTIVE

The present study makes a comparative assessment of the Floppy-Nissen (FN) and Nissen-Rossetti fundoplication (NRF) procedures.

METHODS

Included in the study were 80 patients who presented to the General Surgery Department outpatient clinic of Balcalı Hospital of the Cukurova University Faculty of Medicine with gastroesophageal reflux between March 2010 and March 2013 All patients were operated on by the same surgeon using the laparoscopic FN or NRF techniques in a randomized controlled manner. The preoperative and postoperative reflux-specific and nonspecific gastrointestinal symptoms of the patients were compared.

RESULTS

The duration of symptoms had no effect on the level of satisfaction; regurgitation, bloating and heartburn were more common in those with a longer duration of symptoms Of the patients, 92.5% were satisfied with their resulting condition, and 92.5% were inclined toward the surgery. It was further found that there was no difference between the symptoms or satisfaction levels of the patient groups who underwent the FN procedure and those who underwent the NRF procedure, other than those related to the duration of surgery. laparoscopic NF and the NRF fundoplication treatments, aside from the duration of surgery.

CONCLUSION

Our study revealed no significant difference between the laparoscopic NF and the NRF fundoplication treatments, aside from the duration of surgery.KEY MESSAGESThe Nissen-Rossetti technique can be used safely based on the similarity of its outcomes with those of the classical Nissen technique.Despite the documented success of laparoscopic anti-reflux surgery, the absence of studies comparing surgery and medical treatments prevents these discussions from being concluded.Comparison of Nissen Rossetti and Floppy Nissen Techniques in Laparoscopic Reflux Surgery.

Mid-term Outcomes of Nissen Fundoplication Versus Roux-en-y Gastric Bypass for Primary Management of Gastroesophageal Reflux Disease in Patients With Obesity

INTRODUCTION

The efficacy and outcomes of laparoscopic Nissen fundoplication (LNF) in patients with obesity is controversial. Specifically, concerns regarding long-term outcomes and recurrence in the setting of obesity has led to interest in laparoscopic Roux-en-Y gastric bypass (RYGB).

METHODS

In this retrospective cohort study, we studied patients with obesity who underwent either LNF or RYGB for gastroesophageal reflux disease. Baseline demographics, clinical variables, operative outcomes, and symptom severity scores were compared.

RESULTS

Baseline demographics, operative outcomes, and quality-of-life scores were similar. Proton pump inhibitor usage, quality-of-life, symptom severity scores, and satisfaction with the operation were similar between groups at mid-term follow-up.

DISCUSSION

RYGB and LNF produced similar improvements in disease-specific quality of life with similar rates of complications, side effects, and need for reoperation. This demonstrates that RYGB and LNF represent possible options for surgical management of gastroesophageal reflux disease in obese patients.

Robotic single port anti-reflux surgery: Initial worldwide experience of two cases with a novel surgical approach to treat gastroesophageal reflux disease

INTRODUCTION

To date, no anti-reflux operations have been reported with the new da Vinci Single-Port (single port (SP)) robotic platform. We aimed to describe this novel surgical approach and evaluate its safety and feasibility.

METHODS

All robotic SP operations were performed under an Institutional Review Board approved protocol.

RESULTS

Two patients underwent robotic SP anti-reflux surgery through a single incision of 2.7 cm (one Nissen-fundoplication and one re-Redo Nissen-fundoplication). The mean docking-time was 2.5 (2-3) minutes and mean console-time was 147 (119-155) minutes. No additional ports were needed, and no intraoperative complications occurred. Patients tolerated a soft diet on postoperative day 1 and were discharged on POD-2 and 3.

CONCLUSION

Robotic SP anti-reflux surgery appears to be safe and feasible. This platform offers similar advantages to the multiport robotic surgery, while adding lower invasiveness and an improved cosmesis. Further studies are needed to confirm our results and evaluate long-term outcomes of this surgical approach.

Short-term parent reported recovery following open and laparoscopic fundoplication

BACKGROUND

It is assumed that children recover faster after laparoscopic (LF) than after open fundoplication (OF). As this has not been confirmed in any randomized study (RCT), we have in a subsection of a larger RCT compared parent reported recovery of children after LF and OF.

METHODS

Postoperative symptoms, use of analgesics, overall well-being, and time to return to school/day-care were recorded in a subsection of children enrolled in a RCT comparing LF and OF. Ethical approval and parental consent were obtained.

RESULTS

Fifty-five children (LF: n = 27, OF: n = 28) of the 88 enrolled in the RCT, were included in the short term follow up on parent reported recovery. Caregivers were interviewed median 28 days [interquartile range (IQR) 22-36] postoperatively. There was no significant difference regarding improvement in overall well-being (LF: 63%, OF: 68%, p = 0.70), new-onset dysphagia (LF: 30%, OF: 18%, p = 0.08), use of analgesics (LF: 15%, OF: 14%, p = 1.00), or time to return to school/day-care (LF: median 7 days [IQR 5-14] vs. OF: 12 days [IQR 7-15], p = 0.35).

CONCLUSION

We could not demonstrate faster recovery after LF than after OF. Most children had returned to school/day-care after 2 weeks and had improved overall well-being 1 month after surgery.

Non-active implantable device treating acid reflux with a new dynamic treatment approach: 1-year results : RefluxStop™ device; a new method in acid reflux surgery obtaining CE mark

Background

RefluxStop™ is an implantable, non-active, single use device used in the laparoscopic treatment of GERD. RefluxStop™ aims to block the movement of the LES up into the thorax and keep the angle of His in its original, anatomically correct position. This new device restores normal anatomy, leaving the food passageway unaffected.

Methods

In a prospective, single arm, multicentric clinical investigation analyzing safety and effectiveness of the RefluxStop™ device to treat GERD, 50 subjects with chronic GERD were operated using a standardized surgical technique between December 2016 and September 2017. They were followed up for 1 year (CE-mark investigation 6-months). Primary safety outcome was prevalence of serious adverse events related to the device, and primary effectiveness outcome reduction of GERD symptoms based on GERD-HRQL score. Secondary outcomes were prevalence of adverse events other than serious adverse events, reduction of total acid exposure time in 24-h pH monitoring, and reduction in average daily PPI usage and subject satisfaction.

Results

There were no serious adverse events related to the device. Average GERD-HRQL total score at 1 year improved 86% from baseline (p < 0.001). 24-h pH monitoring compared to baseline showed a mean reduction percentage of overall time with pH < 4 from 16.35 to 0.80% at the 6-month visit (p < 0.001), with 98% of subjects showing normal 24-h pH. At 1 year: No new cases of dysphagia were recorded, present in 2 subjects, which existed already at baseline. Regular daily PPI usage occurred in all 50 subjects at baseline. At 1-year follow-up, only 1 subject took regular daily PPIs due to a too low placement of the device thereby prohibiting its function. None or minimal occasional episodes of regurgitation occurred in 97.8% of evaluable subjects. Gas bloating disappeared in 30 subjects and improved in 7 subjects.

Conclusion

The new principle of RefluxStop™ is safe and effective to treat GERD according to investigation results. At 1-year follow-up, both the GERD-HRQL score and 24-h pH monitoring results indicate success for the new treatment principle. In addition, with the dynamic treatment for acid reflux, which avoids compressing the food passageway, prevalence of dysphagia and gas bloating are significantly reduced.

How to select patients for antireflux surgery? The ICARUS guidelines (international consensus regarding preoperative examinations and clinical characteristics assessment to select adult patients for antireflux surgery)

OBJECTIVE

Antireflux surgery can be proposed in patients with GORD, especially when proton pump inhibitor (PPI) use leads to incomplete symptom improvement. However, to date, international consensus guidelines on the clinical criteria and additional technical examinations used in patient selection for antireflux surgery are lacking. We aimed at generating key recommendations in the selection of patients for antireflux surgery.

DESIGN

We included 35 international experts (gastroenterologists, surgeons and physiologists) in a Delphi process and developed 37 statements that were revised by the Consensus Group, to start the Delphi process. Three voting rounds followed where each statement was presented with the evidence summary. The panel indicated the degree of agreement for the statement. When 80% of the Consensus Group agreed (A+/A) with a statement, this was defined as consensus. All votes were mutually anonymous.

RESULTS

Patients with heartburn with a satisfactory response to PPIs, patients with a hiatal hernia (HH), patients with oesophagitis Los Angeles (LA) grade B or higher and patients with Barrett's oesophagus are good candidates for antireflux surgery. An endoscopy prior to antireflux surgery is mandatory and a barium swallow should be performed in patients with suspicion of a HH or short oesophagus. Oesophageal manometry is mandatory to rule out major motility disorders. Finally, oesophageal pH (±impedance) monitoring of PPI is mandatory to select patients for antireflux surgery, if endoscopy is negative for unequivocal reflux oesophagitis.

CONCLUSION

With the ICARUS guidelines, we generated key recommendations for selection of patients for antireflux surgery.

A retrospective multicenter analysis on redo-laparoscopic anti-reflux surgery: conservative or conversion fundoplication?

BACKGROUND

Nearly 20% of patients who undergo hiatal hernia (HH) repair and anti-reflux surgery (ARS) report recurrent HH at long-term follow-up and may be candidates for redo surgery. Current literature on redo-ARS has limitations due to small sample sizes or single center experiences. This type of redo surgery is challenging due to rare but severe complications. Furthermore, the optimal technique for redo-ARS remains debatable. The purpose of the current multicenter study was to review the outcomes of redo-fundoplication and to identify the best ARS repair technique for recurrent HH and gastroesophageal reflux disease (GERD).

METHODS

Data on 975 consecutive patients undergoing hiatal hernia and GERD repair were retrospectively collected in five European high-volume centers. Patient data included demographics, BMI, techniques of the first and redo surgeries (mesh/type of ARS), perioperative morbidity, perioperative complications, duration of hospitalization, time to recurrence, and follow-up. We analyzed the independent risk factors associated with recurrent symptoms and complications during the last ARS. Statistical analysis was performed using GraphPad Prism^® and R software^®.

RESULTS

Seventy-three (7.49%) patients underwent redo-ARS during the last decade; 71 (98%) of the surgeries were performed using a minimally invasive approach. Forty-two (57.5%) had conversion from Nissen to Toupet. In 17 (23.3%) patients, the initial Nissen fundoplication was conserved. The initial Toupet fundoplication was conserved in 9 (12.3%) patients, and 5 (6.9%) had conversion of Toupet to Nissen. Out of the 73 patients, 10 (13%) underwent more than one redo-ARS. At 8.5 (1-107) months of follow-up, patients who underwent reoperation with Toupet ARS were less symptomatic during the postoperative period compared to those who underwent Nissen fundoplication (p = 0.005, OR 0.038). Patients undergoing mesh repair during the redo-fundoplication (21%) were less symptomatic during the postoperative period (p = 0.020, OR 0.010). The overall rate of complications (Clavien-Dindo classification) after redo surgery was 11%. Multivariate analysis showed that the open approach (p = 0.036, OR 1.721), drain placement (p = 0.0388, OR 9.308), recurrence of dysphagia (p = 0.049, OR 8.411), and patient age (p = 0.0619, OR 1.111) were independent risk factors for complications during the last ARS.

CONCLUSIONS

Failure of ARS rarely occurs in the hands of experienced surgeons. Redo-ARS is feasible using a minimally invasive approach. According to our study, in terms of recurrence of symptoms, Toupet fundoplication is a superior ARS technique compared to Nissen for redo-fundoplication. Therefore, Toupet fundoplication should be considered in redo interventions for patients who initially underwent ARS with Nissen fundoplication. Furthermore, mesh repair in reoperations has a positive impact on reducing the recurrence of symptoms postoperatively.

Socioeconomic factors and parity of access to robotic surgery in a county health system

Equal access to novel surgical technologies remains a policy concern as hospitals adopt robotic surgery with increasing prevalence. This study sought to determine whether socioeconomic factors influence access to robotic surgery. All laparoscopic and robotic fundoplications and paraesophageal hernia repairs performed by a surgical group over 6 years at a county and two neighboring private hospitals were identified. Robotic use by hospital setting, age, gender, reported ethnicity, estimated income, insurance payer, and diagnosis were examined. Of 418 patients identified, 180 (43%) presented to the county hospital, where subjects were younger (51.1 versus 56.2 years, p < 0.001) with lower estimated income ($50,289 versus $62,959, p < 0.001). In the county setting, there was no difference in reported ethnicity (p = 0.169), estimated income (p = 0.081), or insurance payer (p = 0.535) between groups treated laparoscopically versus robotically. There was no difference in the treatment groups by estimated income in the private hospital setting (p = 0.308). Overall higher estimated income and insurance payer were associated with a higher chance of undergoing robotic procedures (p < 0.001). Presence of a paraesophageal hernia was associated with increased chance of undergoing robotic therapy in all comparisons (p < 0.001). No disparity in access to robotic surgery offered in the county hospital was observed based on age, gender, reported ethnicity, estimated income, or insurance payer. Patients with higher income and private insurers were more likely to present to the private hospital setting where robotics is utilized more often. The presence of a paraesophageal hernia was a significant factor in determining robotic therapy in both settings.

What Are the Advantages of 3D Cameras in Gynaecological Laparoscopy?

Introduction Minimally invasive operative techniques are being used increasingly in gynaecological surgery. The expansion of the laparoscopic operation spectrum is in part the result of improved imaging. This study investigates the practical advantages of using 3D cameras in routine surgical practice. Materials and Methods Two different 3-dimensional camera systems were compared with a 2-dimensional HD system; the operating surgeon's experiences were documented immediately postoperatively using a questionnaire. Results Significant advantages were reported for suturing and cutting of anatomical structures when using the 3D compared to 2D camera systems. There was only a slight advantage for coagulating. The use of 3D cameras significantly improved the general operative visibility and in particular the representation of spacial depth compared to 2-dimensional images. There was not a significant advantage for image width. Depiction of adhesions and retroperitoneal neural structures was significantly improved by the stereoscopic cameras, though this did not apply to blood vessels, ureter, uterus or ovaries. Conclusion 3-dimensional cameras were particularly advantageous for the depiction of fine anatomical structures due to improved spacial depth representation compared to 2D systems. 3D cameras provide the operating surgeon with a monitor image that more closely resembles actual anatomy, thus simplifying laparoscopic procedures.

Antireflux Surgery and Risk of Esophageal Adenocarcinoma: A Systematic Review and Meta-analysis

OBJECTIVE

To investigate the preventive effect of antireflux surgery against esophageal adenocarcinoma (EAC) compared with medical treatment of gastroesophageal reflux disease (GERD) and to the background population.

BACKGROUND

GERD is causally associated with EAC. Effective symptomatic treatment can be achieved with medication and antireflux surgery; however the possible preventive effect on EAC development remains unclear.

METHODS

This systematic review identified 10 studies comparing EAC risk after antireflux surgery with nonoperated GERD patients, including 7 studies of patients with Barrett's esophagus, and 2 studies comparing EAC risk after antireflux surgery to the background population. A fixed-effects Poisson meta-analysis was conducted to calculate pooled incidence rate ratios (IRR) and 95% confidence intervals (CIs).

RESULTS

The pooled IRR in patients after antireflux surgery was 0.76 (95% CI 0.42-1.39) compared with medically treated GERD patients. In patients with Barrett's esophagus, the corresponding IRR was 0.46 (95% CI 0.20-1.08), and 0.26 (95% CI 0.09-0.79) when restricted to publications after 2000. There was no difference in EAC risk between antireflux surgery and medical treatment in GERD patients without known Barrett's esophagus (IRR 0.98, 95% CI 0.72-1.33). The EAC risk remained elevated in patients after antireflux surgery compared with the background population (IRR 10.78, 95% CI 8.48-13.71). Although the clinical heterogeneity of the included studies was high, the statistical heterogeneity was low.

CONCLUSIONS

Antireflux surgery may prevent EAC better than medical therapy in patients with Barrett's esophagus. The EAC risk after antireflux surgery does not seem to revert to that of the background population.

Symptom Relief After Laparoscopic Paraesophageal Hernia Repair Without Mesh

BACKGROUND

Laparoscopic repair of paraesophageal hernia (LPEHR) is considered today the standard of care for this condition. While attention has been mostly focused on the incidence of postoperative radiologic recurrence of a hiatal hernia, few data are available about the effect of the operation on symptoms.

AIMS

In this study, we aim to determine the effect of primary LPEHR on postoperative symptoms.

PATIENTS AND METHODS

One hundred and sixty-two patients underwent LPEH repair in two academic tertiary care centers. Preoperative evaluation included barium swallow (100 %), endoscopy (80 %), manometry (81 %), and pH monitoring (25 %). Type III PEH was the most common (94 %), and it was associated with a gastric volvulus in 27 % of patients.

RESULTS

A fundoplication was performed in all patients: Nissen in 57 %, Dor in 36 %, and Toupet in 6 %. A Collis gastroplasty was added in 6 % of patients. There were no perioperative deaths. The intraoperative complication rate was 7 %. The operation was completed laparoscopically in 98 % of patients. Postoperative complications occurred in four patients, and three needed a second operation. Average follow-up was 24 months. Heartburn, regurgitation, chest pain, dysphagia, respiratory symptoms, and hoarseness improved as a result of the operation. Anemia fully resolved in all patients.

CONCLUSIONS

LPEH repair is safe and effective, and the need for reoperation is rare. Few patients experience postoperative symptoms, and these are easily controlled with acid-reducing medications.

A randomized trial of laparoscopic versus open Nissen fundoplication in children under two years of age

AIMS

The surgery of gastroesophageal reflux disease (GERD) is common in modern pediatric surgical practice. Any differences in perioperative and long-term clinical outcomes following laparoscopic (LN) or open Nissen (ON) fundoplication have not been comprehensively described in young children. This randomized, prospective study examines outcomes following LN versus ON in children<2 years of age.

METHODS

Four surgeons at a single institution enrolled patients under 2 years of age that required surgical management of GERD, who were then randomized to LN or ON between 2005 and 2012. A universal surgical dressing was employed for blinding. Analgesia and enteral feeding pathways were standardized. The primary outcome was postoperative length of stay. Perioperative outcomes and long-term follow up were collected as secondary outcomes and used to compare groups.

RESULTS

Of 39 enrolled patients, 21 were randomized to ON and 18 to LN. Length of postoperative hospital stay, time of advancement to full enteral feeds, and analgesic requirements were not significantly different between treatment cohorts. The LN group experienced longer median operating times (173 vs 91 min, P<0.001) and higher surgical charges ($4450 vs $2722, P=0.002). The incidence of post-discharge complications did not differ significantly between the groups at last follow-up (median 42 months).

CONCLUSIONS

This randomized trial comparing postoperative outcomes following LN vs ON did not detect statistically significant differences in short- or long-term clinical outcomes between these approaches. LN was associated with longer surgical time and higher operating room costs. The benefits, risks, and costs of laparoscopy should be carefully considered in clinical pediatric surgical practice.

Short- and long-term results of laparoscopic versus open anti-reflux surgery: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

There is an ongoing debate about whether laparoscopic anti-reflux surgery (LARS) or open anti-reflux surgery (OARS) is the better option for the surgical treatment of gastroesophageal reflux disease (GERD). This study was aimed to evaluate and compare the short- and long-term results of both surgical strategies by means of a systematic review and meta-analysis.

METHODS

A systematic search of electronic databases (PubMed, Embase, The Cochrane Library) for studies published from 1970 to 2013 was performed. All randomized controlled trials (RCTs) that compared LARS with OARS were included. We analyzed the outcomes of each type of surgery over short- and long-term periods.

RESULTS

Twelve studies met final inclusion criteria (total n = 1,067). A total of 510 patients underwent OARS and 557 had LARS. The pooled analyses showed, despite of longer operation time, the hospital stay and sick leave were significantly reduced in the LARS group. Significant reductions were also observed in complication rates for the LARS group in both short (odds ratio (OR) 0.31, 95 % CI 0.17 to 0.56) and long-term periods (OR 0.24, 95 % CI 0.07 to 0.80). Although complaints of reflux symptoms were more frequent among LARS patients in the short-term follow-up, LARS achieved better control of reflux symptoms in the long-term period (P < 0.05). Reoperation rate, patient's satisfaction, and 24-h pH monitoring were all comparable between the two groups (all P > 0.05).

CONCLUSIONS

LARS is an effective and safe alternative of OARS for the surgical treatment of GERD, which enables a faster convalescence, better control of long-term reflux symptoms, and with reduced risk of complications.

Perioperative outcome of esophageal fundoplication for gastroesophageal reflux disease in obese and morbidly obese patients

BACKGROUND

To determine the perioperative safety of esophageal fundoplication for gastroesophageal reflux disease (GERD) in patients with body mass index (BMI) ≥ 35 kg/m(2).

METHODS

A retrospective review of 4,231 patients who underwent fundoplication for GERD from 2005 to 2009 was performed. Patients were identified via National Surgical Quality Improvement Program and grouped by BMI < 35 versus BMI ≥ 35 kg/m(2). Univariate analysis compared 30-day outcomes.

RESULTS

Of the 4,231 patients, 3,496 (83%) had BMI < 35 kg/m(2) and 735 (17%) had BMI ≥ 35 kg/m(2). Mean BMI for each cohort was 27.9 versus 39.1, respectively. Patients with BMI ≥ 35 kg/m(2) had significantly longer operative times (129.7 vs 118 minutes, P < .0001) and increased American Society of Anesthesiologists scores (2.43 vs 2.3, P = .001). The overall complication rate was 1.96%. No difference was demonstrated by BMI in complication rate or hospital length of stay. Increased American Society of Anesthesiologists score, diabetes, black race, longer operative time, and intraoperative transfusion significantly increased postoperative complication rates.

CONCLUSIONS

No increased risk is conferred to morbidly obese patients who undergo fundoplication for GERD management. This study identified independent patient risk factors for postoperative complication following esophageal fundoplication.

Laparoscopic floppy Nissen fundoplication: 11-year follow-up

BACKGROUND

There are few published reports on the outcomes of ≥ 10 years after a laparoscopic floppy Nissen fundoplication (LFNF).

MATERIALS AND METHODS

From April 1994 to January 2012, 567 patients underwent LFNF and the outcomes of 211 cases were determined (from April 1994 to October 2000).

RESULTS

Outcomes at ≥ 11 years after surgery was available for 178 patients (84.3%) of which 167 (93.8%) had no heartburn or mild heartburn, 8 (4.5%) had moderate heartburn, and 3 had (1.7%) severe heartburn. Dysphagia was nonexistent or mild in 153 (85.9%), whereas the remaining 14.1% presented moderate to severe symptoms. Reports of 69.1% patients showed none or mild symptoms of abdominal bloating, that of 23% patients showed moderate discomfort, and reports of 7.8% showed severe bloating. Satisfaction score was 8.6 (of 10). A further surgical procedure was required for 7 patients (3.9%): 4 for recurrent reflux and 3 for dysphagia (2 for a tight wrap and 1 for a tight esophageal hiatus). Postoperative dysphagia sufficient for an endoscopic dilatation was observed in 4 patients (2.3%), where 3 were successfully managed with a single dilatation procedure and the last patient underwent several dilatations before adequate swallowing.

CONCLUSION

LFNF is an effective long-term treatment for gastroesophageal reflux disease, yielding similar results to open fundoplication.

How does robotic anti-reflux surgery compare with traditional open and laparoscopic techniques: a cost and outcomes analysis

BACKGROUND

Conventional laparoscopic fundoplications (CLF) have been the gold standard for Nissen fundoplications (NFs) for two decades. The advent of a robotic approach for fundoplication procedures creates a potential alternative. Thus, we used a national database to examine perioperative outcomes with respect to open, laparoscopic, and robotic approaches.

METHODS

The University Health System Consortium is an alliance of medical centers, numbering over 115 academic institutions and their 271 affiliated hospitals. We used International Classification of Diseases codes to elicit patients over the age of 18 years who received NF procedures.

RESULTS

A total of 12,079 patients of similar demographic background received fundoplication procedures from October 2008 to June 2012. Of those, 2,168 were open fundoplications (OF), 9,572 were CLF, and 339 were robot-assisted laparoscopic fundoplications (RLF). CLF and RLF displayed no significance in mortality (0.1 vs. 0 %; p = 0.5489), morbidity (4.0 vs. 5.6 %; p = 0.1744), length of stay (2.8 ± 3.6 vs. 3.0 ± 3.5; p = 0.3242), and intensive care unit (ICU) cases (8.4 vs. 11.5 %; p = 0.051). However, CLF remained superior, with a lower 30-day re-admission rate (1.8 vs. 3.6 %; p < 0.05) and cost (US$7,968 ± 6,969 vs. US$10,644 ± 6,041; p < 0.05). When RLF was compared with OF, RLF had significantly improved morbidity (5.6 vs. 11 %; p < 0.05), length of stay (6.1 ± 7.2 vs. 3.0 ± 3.5 days; p < 0.05), less ICU admission (11.5 vs. 23.1 %; p <0.05) and less cost (US$10,644 ± 6,041 vs. US$12,766 ± 13,982; p < 0.05).

CONCLUSIONS

Current data suggests that robot-assisted NF procedures have similar patient outcomes to conventional laparoscopic NF, with the exception of added cost and higher re-admission rate. While the higher costs are expected given the new technology, increasing re-admission rates are concerning and may represent the level of experience of the surgeon as well as the robotic learning curve.

[The Mexican consensus on gastroesophageal reflux disease. Part II]

OBJECTIVE

To update the themes of endoscopic and surgical treatment of Gastroesophageal Reflux Disease (GERD) from the Mexican Consensus published in 2002.

METHODS

Part I of the 2011 Consensus dealt with the general concepts, diagnosis, and medical treatment of this disease. Part II covers the topics of the endoscopic and surgical treatment of GERD. In this second part, an expert in endoscopy and an expert in GERD surgery, along with the three general coordinators of the consensus, carried out an extensive bibliographic review using the Embase, Cochrane, and Medline databases. Statements referring to the main aspects of endoscopic and surgical treatment of this disease were elaborated and submitted to specialists for their consideration and vote, utilizing the modified Delphi method. The statements were accepted into the consensus if the level of agreement was 67% or higher.

RESULTS

Twenty-five statements corresponding to the endoscopic and surgical treatment of GERD resulted from the voting process, and they are presented herein as Part II of the consensus. The majority of the statements had an average level of agreement approaching 90%.

CONCLUSION

Currently, endoscopic treatment of GERD should not be regarded as an option, given that the clinical results at 3 and 5 years have not demonstrated durability or sustained symptom remission. The surgical indications for GERD are well established; only those patients meeting the full criteria should be candidates and their surgery should be performed by experts.

Three-dimensional vision enhances task performance independently of the surgical method

BACKGROUND

Within the next few years, the medical industry will launch increasingly affordable three-dimensional (3D) vision systems for the operating room (OR). This study aimed to evaluate the effect of two-dimensional (2D) and 3D visualization on surgical skills and task performance.

METHODS

In this study, 34 individuals with varying laparoscopic experience (18 inexperienced individuals) performed three tasks to test spatial relationships, grasping and positioning, dexterity, precision, and hand-eye and hand-hand coordination. Each task was performed in 3D using binocular vision for open performance, the Viking 3Di Vision System for laparoscopic performance, and the DaVinci robotic system. The same tasks were repeated in 2D using an eye patch for monocular vision, conventional laparoscopy, and the DaVinci robotic system.

RESULTS

Loss of 3D vision significantly increased the perceived difficulty of a task and the time required to perform it, independently of the approach (P < 0.0001-0.02). Simple tasks took 25 % to 30 % longer to complete and more complex tasks took 75 % longer with 2D than with 3D vision. Only the difficult task was performed faster with the robot than with laparoscopy (P = 0.005). In every case, 3D robotic performance was superior to conventional laparoscopy (2D) (P < 0.001-0.015).

CONCLUSIONS

The more complex the task, the more 3D vision accelerates task completion compared with 2D vision. The gain in task performance is independent of the surgical method.

Endoscopic fundoplication for the treatment of gastroesophageal reflux disease: initial experience

OBJECTIVE

Transoral incisionless fundoplication (TIF) is a promising approach for gastroesophageal reflux disease (GERD) that may decrease morbidity compared with conventional antireflux procedures. We report our initial experience with this minimally invasive approach.

METHODS

Over a 24-month period, 46 patients (mean age, 49 years; 50% female) underwent 48 TIF procedures. All procedures were performed under general anesthesia. Two surgeons participated in all cases; one served as the endoscopist, and the other performed the partial fundoplication. Heartburn severity was measured using the GERD health-related quality of life (GERD-HRQL) instrument (best score = 0, worst score = 45), which includes an additional question assessing overall satisfaction.

RESULTS

Preoperatively, 33 (72%) of 46 patients had small (<3 cm) hiatal hernias, and none had undergone any previous antireflux procedures. Preoperative workup included manometry and barium esophagogram, with pH testing reserved for patients with atypical symptoms or typical symptoms and a lack of response to proton-pump inhibitors. The mean procedure time was 83 minutes (range, 36-180 minutes). The mean procedure time decreased after the first 5 cases from 122 to 78 minutes (P = .001). Mean length of stay was 1.3 days. One patient was readmitted with aspiration pneumonia. Three patients had minor complications (1 had minor bleeding from a suture site and 2 had urinary retention). There were no perioperative deaths. Mean follow-up was 140 days. The mean GERD-HRQL scores improved significantly (23 vs 7; P < .001). There were 22 patients with follow-up greater than 90 days (mean follow-up, 240 days). GERD-HRQL scores remained significantly improved for these patients (23 vs 8; P = .001). Four patients from the entire group (8.6%) had no improvement, in 3 instances due to breakdown of the wrap. Two patients were treated with repeat endoscopic fundoplication and 1 was treated with laparoscopic Nissen fundoplication, and all had a significant improvement in symptoms after reoperation.

CONCLUSIONS

TIF is effective at short-term follow-up and safe for patients with GERD. However, long-term follow-up and randomized trials are required to assess the efficacy and durability of this approach compared with conventional surgical repair.

Twenty years of laparoscopic fundoplication for GERD

The first laparoscopic Nissen fundoplication was performed 20 years ago. Surgical management of gastroesophageal reflux disease (GERD) should be offered only to appropriately studied and selected patients, with the ultimate aim of improving the well-being of the individual, the "quality of life." The choice of fundoplication should be dictated by the surgeon's preference and experience.

Robotic redo fundoplication for incompetent wrapping after antireflux surgery: A case report

INTRODUCTION

Incidence of gastroesophageal reflux disease (GERD) is high. antireflux surgery with specific indications could be an option. Nissen fundoplication is the most popular surgical procedure for GERD, and recent results using laparoscopy have reported excellent short- and mid-term results. Regarding surgical outcome of antireflux surgery, the rate of complications has been reported as below 2.4%, but rare cases still require reoperation.

PRESENTATION OF CASE

A 53-year old male patient underwent laparoscopic Nissen fundoplication three years ago owing to gastroesophageal reflux disease (GERD) troubled by dysphagia and heartburn However, despite undergoing surgery, his symptoms did not show improvement .A robotic redo fundoplication was planned. The patient recovered uneventfully, and the esophagography on postoperative day four revealed improvement of previous upward contrast reflux and distension of the distal esophagus during swallowing had disappeared. Dysphagia and heartburn had still not occurred at one year follow-up.

DISCUSSION

Redo antireflux surgery for postoperative stricture is not an easy procedure due to postoperative adhesion and anatomical change. Robotic surgery may be more helpful for precise dissection of the adhesion site by a previous operation and robotic suturing for re-fundoplication was more effective.

CONCLUSION

Re-do fundoplication using a robot, which is a complicated procedure compared with primary anti-reflux surgery would be a general procedure in the near future.

Clinical outcomes of atypical extra-esophageal reflux symptoms following laparoscopic antireflux surgery

INTRODUCTION

While it is well established that antireflux surgery is effective in relieving typical gastroesophageal reflux disease (GERD) symptoms such as heartburn and regurgitation, it is currently unclear whether atypical symptoms (cough, hoarseness, wheeze) foreshadow a less satisfactory outcome following laparoscopic antireflux surgery (LARS). The purpose of this study is to critically analyze the clinical outcomes of atypical symptoms in patients undergoing LARS.

METHODS

Patients scheduled for LARS for GERD were prospectively enrolled over a 7-year period; all subjects underwent preoperative high-resolution manometry (HRM) and had evidence of GERD on ambulatory pH study. Cough, wheeze, and hoarseness were considered atypical symptoms. During preoperative and postoperative examinations, patients completed detailed foregut symptomatology questionnaires, using both 5-point Likert and 10-point visual analog scales (VAS) to document typical as well as atypical symptoms. Atypical symptom burden was calculated as a sum of VAS for the three atypical symptoms, termed the atypical score (ATS). HRM patterns were grouped into normal, spastic, and hypomotile. Statistical significance (p < 0.05) was determined using paired t-test, and analysis of variance with post hoc least significant difference (LSD).

RESULTS

One hundred thirteen patients (age 49 ± 1.26 years, range 20-84 years, M:F 47:66) with mean follow-up of 28 ± 2.31 months (range 1-92 months) fulfilled inclusion criteria, having mean modified DeMeester score of 45.5 ± 2.78. Heartburn was noted in 84.1%, while atypical symptoms of some degree were reported by 92.0% (104 patients). Heartburn improved from a preoperative score of 7.1 ± 0.54 to 0.9 ± 0.24 after LARS, and ATS improved from 8.9 ± 0.71 to 2.2 ± 0.42. Significant improvements were noted for all atypical symptoms analyzed (p < 0.0001 for each). Improvement in atypical symptoms was least in the presence of hypomotility features on HRM (21.7% improvement), compared with normal motility (72.4%) and spastic features (83.9%). Preoperative atypical score (p < 0.0001) and esophageal hypomotility (p = 0.04) demonstrated a linear relationship with postoperative atypical score.

CONCLUSIONS

In an unselected cohort of patients undergoing LARS, atypical GERD symptoms improved as significantly as typical symptoms. Symptom improvement was significantly lower in the presence of esophageal hypomotility and with higher symptomatic state. Therefore, patients with severe atypical symptoms or hypomotile esophagus may not achieve the same clinical satisfaction from LARS.

The evolution of laparoscopic antireflux surgery and its influence on postoperative stay

Laparoscopic fundoplication is an established treatment for refractory gastro-oesophageal reflux disease. This study aims to compare the outcome of two laparoscopic antireflux techniques in a regional specialist unit. A sequential audit was carried out on patients undergoing laparoscopic Nissen (LN: performed May 1994 to November 2000) or laparoscopic anterior (LA: performed March 2001 to December 2004) fundoplication. Patient satisfaction was assessed by postal questionnaire. The cohorts undergoing each operation were also divided into two chronological groups of 51 patients, to study the effect of possible learning curve progression on the number of nights spent in the hospital postoperatively. In all, 142/204 (70%) questionnaires were returned from patients with follow-up ranging from 5 to 40 months postoperation. Overall, 102/142 (72%) reported a good or excellent outcome. Patients who underwent LA had a higher rate of antacid medication use (LN 17.4% versus LA 34.2%, P = 0.036) but there was a higher score for inability to belch following LN (LN 2.03 versus LA 1.53, P = 0.034). When comparing the chronologically divided cohorts, LN was associated with a significantly longer hospital stay than LA (P < 0.001, Mann-Whitney U test). There was a significant decrease in hospital stay from the first to second group of 51 LNs (P < 0.001, Mann-Whitney U test) and a further significant reduction in hospital stay from the first 51 to second 51 LAs (P < 0.001, Mann-Whitney U test). In conclusion, both procedures provide good symptom control. Increased requirement for acid suppression following LA and inability to belch following LN, may suggest more long-term durability of the LN wrap. The decrease in the number of nights spent in hospital may be related to the procedure performed but seems more likely to be an effect of increasing volume of surgical experience.

Endoscopic and laparoscopic treatment of gastroesophageal reflux

Gastroesophageal reflux is extremely common in Western countries. For selected patients, there is an established role for the surgical treatment of reflux, and possibly an emerging role for endoscopic antireflux procedures. Randomized trials have compared medical versus surgical management, laparoscopic versus open surgery and partial versus total fundoplications. However, the evidence base for endoscopic procedures is limited to some small sham-controlled studies, and cohort studies with short-term follow-up. Laparoscopic fundoplication has been shown to be an effective antireflux operation. It facilitates quicker convalescence and is associated with fewer complications, but has a similar longer term outcome compared with open antireflux surgery. In most randomized trials, antireflux surgery achieves at least as good control of reflux as medical therapy, and these studies support a wider application of surgery for the treatment of moderate-to-severe reflux. Laparoscopic partial fundoplication is an effective surgical procedure with fewer side effects, and it may achieve high rates of patient satisfaction at late follow-up. Many of the early endoscopic antireflux procedures have failed to achieve effective reflux control, and they have been withdrawn from the market. Newer procedures have the potential to fashion a surgical fundoplication. However, at present there is insufficient evidence to establish the safety and efficacy of endoscopic procedures for the treatment of gastroesophageal reflux, and no endoscopic procedure has achieved equivalent reflux control to that achieved by surgical fundoplication.

Ten-year outcome of laparoscopic and conventional nissen fundoplication: randomized clinical trial

OBJECTIVE

To compare 10 years outcome of a multicenter randomized controlled trial on laparoscopic (LNF) and conventional Nissen fundoplication (CNF), with focus on effectiveness and reoperation rate.

SUMMARY OF BACKGROUND DATA

LNF has replaced CNF as surgical treatment for gastroesophageal reflux disease (GERD). Decisions are based on equal short-term effectiveness and reduced morbidity, but confirmation by long-term level 1 evidence is lacking.

METHODS

From 1997 to 1999, 177 proton pump inhibitor (PPI)-refractory GERD patients were randomized to undergo LNF or CNF. The 10 years results of surgery on reflux symptoms, general health, PPI use, and reoperation rates, are described. High-resolution manometry, 24-hour pH-impedance monitoring and barium swallow were performed in symptomatic patients only.

RESULTS

A total of 148 patients (79 LNF, 69 CNF) participated in this 10-year follow-up study. GERD symptoms were relieved in 92.4% and 90.7% (NS) after LNF and CNF, respectively. Severity of heartburn and dysphagia were similar, but slightly more patients had relief of regurgitation after LNF (98.7% vs. 91.0%; P = 0.030). The percentage of patients using PPIs slowly increased with time in both groups to 26.6% for LNF and 22.4% for CNF (NS). General health (74.7% vs. 72.7%; NS) and quality of life (visual analogue scale score: 65.3 vs. 61.4; NS) improved similarly in both groups. The percentage of patients who would have opted for surgery again was similar as well (78.5% vs. 72.7%; NS). Twice as many patients underwent reoperation after CNF compared with LNF (12 [15.2%] vs. 24 [34.8%]; P = 0.006), including a higher number of incisional hernia corrections (2 vs. 9; P = 0.015). Mean interval between operation and reintervention was longer after CNF (22.9 vs. 50.6 months; P = 0.047). Of the patients who were dependent on daily PPI therapy at 10 years (LNF 10, CNF 10), 7 patients (LNF 3, CNF 4) had recurrent GERD on pH-impedance monitoring, 5 of them with some form of anatomic recurrence. A total of 13 of 20 (65.0%) patients did not have recurrent GERD. Fourteen patients had an abnormal high-resolution manometry.

CONCLUSIONS

CNF carries a higher risk for surgical reintervention compared with LNF, mainly due to incisional hernia corrections. The 10-year effectiveness of LNF and CNF is comparable in terms of improvement of GERD symptoms, PPI use, quality of life, and objective reflux control. Consequently, the long-term results from this trial lend level 1 support to the use of LNF as the surgical procedure of choice for GERD.

Meta-analysis of randomized clinical trials comparing open and laparoscopic anti-reflux surgery

OBJECTIVES

The aim of this study was to conduct a meta-analysis of randomized evidence to determine the relative merits of laparoscopic anti-reflux surgery (LARS) and open anti-reflux surgery (OARS) for proven gastro-esophageal reflux disease (GERD).

METHODS

A search of the Medline, Embase, Science Citation Index, Current Contents, and PubMed databases identified all randomized clinical trials that compared LARS and OARS and that were published in the English language between 1990 and 2007. A meta-analysis was carried out in accordance with the QUOROM (Quality of Reporting of Meta-Analyses) statement. The six outcome variables analyzed were operating time, hospital stay, return to normal activity, perioperative complications, treatment failure, and requirement for further surgery. Random-effects meta-analyses were carried out using odds ratios (ORs) and weighted mean differences (WMDs).

RESULTS

Twelve trials were considered suitable for the meta-analysis. A total of 503 patients underwent OARS and 533 had LARS. For three of the six outcomes, the summary point estimates favored LARS over OARS. There was a significant reduction of 2.68 days in the duration of hospital stay for the LARS group compared with that for the OARS group (WMD: -2.68, 95% confidence interval (CI): -3.54 to -1.81; P<0.0001), a significant reduction of 7.75 days in return to normal activity for the LARS group compared with that for the OARS group (WMD: -7.75, 95% CI: -14.37 to -1.14; P=0.0216), and finally, there was a statistically significant reduction of 65% in the relative odds of complication rates for the LARS group compared with that for the OARS group (OR: 0.35, 95% CI: 0.16-0.75; P=0.0072). The duration of operating time was significantly longer (39.02 min) in the LARS group (WMD: 39.02, 95% CI: 17.99-60.05; P=0.0003). Treatment failure rates were comparable between the two groups (OR: 1.39, 95% CI: 0.71-2.72; P=0.3423). Despite this, the requirement for further surgery was significantly higher in the LARS group (OR: 1.79, 95% CI: 1.00-3.22; P=0.05).

CONCLUSIONS

On the basis of this meta-analysis, the authors conclude that LARS is an effective and safe alternative to OARS for the treatment of proven GERD. LARS enables a faster convalescence and return to productive activity, with a reduced risk of complications and a similar treatment outcome, than an open approach. However, there is a significantly higher rate of re-operation (79%) in the LARS group.

Laparoscopic fundoplication compared with laparoscopic gastric bypass in morbidly obese patients with gastroesophageal reflux disease

BACKGROUND

Gastroesophageal reflux disease (GERD) is commonly associated with morbid obesity. Laparoscopic fundoplication is a standard surgical treatment for GERD, and laparoscopic gastric bypass has been shown to effectively resolve GERD symptoms in the morbidly obese. We sought to compare the in-hospital outcomes of morbidly obese patients who underwent laparoscopic fundoplication for the treatment of GERD versus laparoscopic gastric bypass for the treatment of morbid obesity and related conditions, including GERD, at U.S. academic medical centers.

METHODS

Using the "International Classification of Diseases, 9th Revision" procedural and diagnoses codes for morbidly obese patients with GERD, we obtained data from the University HealthSystem Consortium database for all patients who underwent laparoscopic fundoplication or laparoscopic gastric bypass from October 2004 to December 2007 (n=27,264). The outcome measures included the patient demographics, length of stay, in-hospital overall complications, mortality, risk-adjusted mortality ratio (observed to expected mortality), and hospital costs.

RESULTS

Compared with the patients who underwent laparoscopic gastric bypass, those who underwent laparoscopic fundoplication had a lower severity of illness score (P<.05). The overall in-hospital complications were significantly lower in the laparoscopic gastric bypass group (P<.05). The mean length of stay, observed mortality, risk-adjusted mortality, and hospital costs were comparable between the 2 treatment groups.

CONCLUSION

Laparoscopic gastric bypass is as safe as laparoscopic fundoplication for the treatment of GERD in the morbidly obese. Hence, morbidly obese patients with GERD should be referred for bariatric surgery evaluation and offered laparoscopic gastric bypass as a surgical option.

Fundoplication for gastroesophageal reflux and factors associated with the outcome 6 to 10 years after the operation: multivariate analysis of prognostic factors using the propensity score

BACKGROUND

The impact from the mode of operation (partial vs total fundoplication) on long-term outcome after fundoplication still is unknown, although short-term randomized studies have not shown significant differences in the efficacy of reflux control. To obtain some insight concerning the long-term results, the data of a nonrandomized cohort were analyzed using propensity score statistics.

METHODS

For 134 patients who underwent laparoscopic fundoplication for gastroesophageal reflux disease (GERD), the time until recurrence of reflux symptoms was assessed. The impact of putative prognostic factors and the mode of operation (partial vs total fundoplication) on outcome were tested for significance using univariate and multivariate statistics, including the propensity score, correcting for nonrandomized treatment groups. The follow-up period was 60 to 123 months (median, 93 months). In this study, 45 patients had a partial (Toupet) fundoplication, and 89 patients underwent a total (Nissen) fundoplication.

RESULTS

The rate of recurrence after 93 months (the median follow-up interval) was 14% after Nissen and 9% after Toupet fundoplication (nonsignificant difference) as estimated according to Kaplan and Meier. Massive acid exposure to the esophagus was associated with an increased risk of recurrence for 23% of the patients with a DeMeester score of 50 or higher, but only for 9% of the patients with less severe reflux (DeMeester score <50; p < 0.05). Multiple proportional hazard regression using the propensity score did not show additional significance for the variables of age, gender, presence of a Barrett esophagus, and mode of operation.

CONCLUSION

The operation method did not have a significant impact on the efficacy of laparoscopic fundoplication in a cohort during a follow-up period of 60 to 123 months (median, 93 months).

Laparoscopic antireflux surgery for the elderly: a surgical and quality-of-life study

PURPOSE

Laparoscopic antireflux surgery (LARS) has long been introduced as an alternative method for the treatment of gastroesophageal reflux disease (GERD) in young adults. However, the safety of this procedure and the associated improvement in the quality of life for the elderly are rarely discussed. This study compared the results between young and elderly patients who underwent laparoscopic fundoplication for the treatment of GERD.

METHODS

From January 1999 to January 2006, there were 231 adult patients who underwent LARS for GERD at a single institute. Among all patients, 33 patients were older than 70 years old (14.3%, 73.0 +/- 1.9, range 70-76), 198 patients were younger than 70 years old (85.7%, 46.6 +/- 11.5, range 20-69). The clinical characteristics, operation time, postoperative hospital stay, surgical complications, and quality of life were retrospectively analyzed.

RESULTS

The mean operation time had no significant difference between the younger group and the elderly group. The mean postoperative hospital stay in the elderly group was slightly longer than the younger group (4.1 +/- 2.5 days vs 3.4 +/- 1.3 days, P = 0.19). There were no mortalities and no major complications found in each group. No patients required conversion to an open procedure. Four patients had minor complications (three in the elderly group, rate: 9.0%; one in the younger group, rate: 0.5%, P < 0.05). There were two patients in the nonelderly group who had recurrence. A comparison of the preoperative and postoperative Gastro-Intestinal Quality of Life Index (GIQLI) scores showed significant improvements (99.3 +/- 19.2 points, and 110.2 +/- 20.6 points, respectively, P < 0.05) with no significant difference between the two groups.

CONCLUSION

Laparoscopic antireflux surgery thus appears to provide an equivalent degree of safety and symptomatic relief for elderly patients with GERD as that observed in young patients.

Comparison of iatrogenic splenectomy during open and laparoscopic colon resection

Iatrogenic splenic injury requiring splenectomy is a well-recognized and potentially serious complication of colon resection. Iatrogenic splenectomy is associated with significant morbidity and mortality, including bleeding and the postsplenectomy sepsis syndrome. Our study aims to compare the incidence of iatrogenic splenectomy in laparoscopic colon resection with that of open colon resection over an 11-year-period at Mount Sinai. A retrospective chart review of all patients undergoing colon resection at Mount Sinai Medical Center during the last 11 years was performed to identify patient demographics, procedure, indication, and outcome. There was a significant difference (P=0.03) in the incidence of iatrogenic splenectomy during open colectomy (13/5477, 0.24%) versus laparoscopic colectomy (0/1911, 0%). All cases complicated by iatrogenic splenectomy involved splenic flexure mobilization. Laparoscopy has many recognized advantages over open procedures, including shorter recovery and length of stay. This retrospective review of our experience at Mount Sinai presents another potential benefit of the laparoscopic approach to colon resection.

Quality of life convergence of laparoscopic and open anti-reflux surgery for gastroesophageal reflux disease

Although laparoscopic anti-reflux surgery (LARS) has become the surgical treatment of choice for gastroesophageal reflux disease (GERD), it is unclear whether the quality of life (QoL) advantage of LARS over open anti-reflux surgery (OARS) persists in the long term. The purpose of this study was to compare long-term QoL between LARS and OARS patients. A prospectively gathered database of all patients who underwent either LARS or OARS for symptomatic GERD was reviewed. Preoperatively, patients completed the GERD- health-related quality of life (HRQL) symptom severity questionnaire (best score 0, worst score 50), and the Medical Outcome Short Form (36) (SF-36) generic bodily QoL instrument (eight domains, physical functioning, PF; role - physical, RP; role - emotional, RE; bodily pain, BP; vitality, mental health, social functioning, SF; general health, best score 100, worst score 0). Postoperatively, patients completed both questionnaires at 6 weeks and a least 1 year. Data are presented as medians and statistically analyzed using the Mann-Whitney U-test. A beta-error was determined to assess adequacy of sample size. A total of 289 patients underwent LARS and 124 OARS. At 6 weeks there were statistically significantly better scores for LARS in the domains of PF, RP, RE, BP and SF. However, after 1 year, there were no statistically significant differences. The beta-error for non-statistically significant differences were all < 0.2, which is considered an adequate sample size. Although LARS does produce better QoL scores in the early postoperative period, after 1 year, these scores converge.

Comparison of long-term outcome of laparoscopic and conventional nissen fundoplication: a prospective randomized study with an 11-year follow-up

OBJECTIVE

The aim of this study was to compare the long-term objective and subjective outcomes of laparoscopic and open Nissen fundoplication in a randomized clinical trial with an 11-year follow-up.

SUMMARY BACKGROUND DATA

Laparoscopic Nissen fundoplication has become the method of choice in antireflux surgery, replacing its open counterpart despite the lack of long-term results from controlled clinical studies.

METHODS

Between April 1992 and June 1995, 110 consecutive patients were randomized to either laparoscopic (LAP) or conventional (open) Nissen fundoplication. The objective long-term follow-up consisted of an upper gastrointestinal endoscopy and a clinical assessment; the subjective long-term outcome was investigated by personal interviews using a structured questionnaire.

RESULTS

Forty-nine patients in the LAP group and 37 patients in the open group were available for evaluation. Late subjective results, including postoperative symptoms and evaluation of the surgical result, were similar in both groups. With the benefit of hindsight, 73.7% of the patients in the open group and 81.8% in the LAP group would again choose surgical treatment (P = 0.3042). In the LAP group, there were 5 (13.2%) partially or totally disrupted plications compared with the 14 (40.0%) disrupted plications in the open group (P = 0.0152). There were 10 incisional hernias in the open group compared with none in the LAP group (P < 0.001).

CONCLUSIONS

At long-term follow-up, the open and LAP approaches for the Nissen fundoplication have similar long-term subjective symptomatic outcome despite the significantly higher incidence of incisional hernias and defective fundic wraps at endoscopy in the open group defining laparoscopic Nissen fundoplication as the procedure of choice in surgical management of gastroesophageal reflux disease.

Gastric Ulcer After Laparoscopic Fundoplication for Gastroesophageal Reflux Disease: Significance of the Eradication of Helicobacter pylori

The occurrence of gastric ulcers after laparoscopic fundoplication for gastroesophageal reflux disease is not uncommon. Between December 1994 and December 2004, we performed laparoscopic fundoplication in 180 patients, of whom 4 (2.2%) men developed a gastric ulcer during follow-up. The ulcers occurred predominantly in the upper part of the lesser curvature of the stomach, which is definitely different from the usual location of gastric peptic ulcers. All cases we experienced had Helicobacter pylori infection and eradication was attempted in all of them. Although eradication was not possible in 1 patient because of adverse effects to the drugs, successful eradication was obtained in the remaining 3 patients. After successful eradication, these 3 patients were placed under observation without medication and the ulcer has not recurred. The eradication of H. pylori may be an effective therapeutic means to prevent gastric ulcers recurrence after fundoplication.

The extended learning curve for laparoscopic fundoplication: a cohort analysis of 400 consecutive cases

Many studies have looked at the learning curve associated with laparoscopic Nissen fundoplication (LNF) in a given institution. This study looks at the learning curve of a single surgeon with a large cohort of patients over a 10-year period. Prospective data were collected on 400 patients undergoing laparoscopic fundoplication for over 10 years. The patients were grouped consecutively into cohorts of 50 patients. The operating time, the length of postoperative hospital stay, the conversion rate to open operation, the postoperative dilatation rate, and the reoperation rate were analyzed. Results showed that the mean length of operative time decreased from 143 min in the first 50 patients to 86 min in the last 50 patients. The mean postoperative length of hospital stay decreased from 3.7 days initially to 1.2 days latterly. There was a 14% conversion to open operation rate in the first cohort compared with a 2% rate in the last cohort. Fourteen percent of patients required reoperation in the first cohort and 6% in the last cohort. Sixteen percent required postoperative dilatation in the first cohort. None of the last 150 patients required dilatation. In conclusion, laparoscopic fundoplication is a safe and effective operation for patients with gastroesophageal reflux disease. New techniques and better instrumentation were introduced in the early era of LNF. The learning curve, however, continues well beyond the first 20 patients.

Levels of evidence available for techniques in antireflux surgery

The objective of this study was to determine the levels of evidence and grades of recommendations available for techniques in antireflux surgery. Areas of technical controversy in antireflux surgery were identified and developed into eight answerable questions. The external evidence was surveyed using the databases Medline and EMBASE. Abstracts and appropriate articles were identified from January 1966 to December 2005. A set of search strategies was systematically employed to determine the levels of evidence available for each clinical question. Primary outcome measures included the determination of levels of evidence and grade of recommendation based on The Oxford Center for Evidence-Based Medicine. Secondary outcome measures included for randomized controlled trials were Jadad scores, noting the presence of a sample size calculation, and the determination of an effect estimate and the reporting of a confidence interval. Higher quality randomized controlled trials (mostly level 2b, occasional level 1b) existed to answer three questions: whether to complete a 360 degrees or partial wrap; whether or not to divide the short gastric vessels; and whether to perform laparoscopic or open surgery. Lower quality randomized controlled trials were available to determine whether the use of mesh was helpful, whether or not to use a bougie catheter for calibration of the wrap, and whether an anterior or posterior wrap results in a superior outcome. This was deemed to be of inferior grade of recommendation due to the lack (< 2) of trials available and the sole presence of level 2b evidence. The final two questions: whether to complete fundoplication using a thoracic or abdominal approach and whether to use intraoperative manometry relied exclusively upon level 4 evidence and thus received a lower grade of recommendation. A higher Jadad score seemed to be associated with studies having a higher level of evidence available to answer the question. Sample size calculations were given to answer three questions. Effect estimate was difficult to interpret given inconsistent findings, composite outcomes and lack of reported confidence intervals. In conclusion, antireflux surgery has many randomized controlled trials available upon which to base clinical practice. Unfortunately, these are generally of poor quality. We recommend that esophageal surgeons determine consistent outcome measures and endeavor to improve the quality of randomized controlled trials they perform.
