New technology for the division of short gastric vessels during laparoscopic Nissen fundoplication

Division of the short gastric vessels (SGV) is a standard component of laparoscopic Nissen fundoplications (LNF) at our institution. This study compares our original method of vessel control, multifire clip applier (MCA) and sharp division, to the Ultracision Harmonic Scalpel LCS (LCS). Twenty consecutive patients were evaluated in a randomized prospective fashion. Times for SGV division and estimated blood loss (EBL) were recorded. Cost data represent patient charges for use of either the MCA or LCS and the charge for operative time. Use of the LCS produced a significant reduction in the time required for SGV division and in the charges to the patient.

Comparison of objective outcomes following laparoscopic Nissen fundoplication versus laparoscopic gastric bypass in the morbidly obese with heartburn

Background: Heartburn and gastroesophageal reflux disease (GERD) affects approximately 25–50% of morbidly obese patients. Although objective physiologic testing has been reported extensively in patients following Nissen fundoplication, there are no previous reports of such testing in morbidly obese patients. A life-saving surgical alternative for the morbidly obese patient is gastric bypass surgery, which usually improves heartburn symptoms in addition to many serious health conditions such as diabetes, hypertension, and sleep apnea. We hypothesized that, in morbidly obese patients, gastric bypass surgery would be as effective as Nissen fundoplication in reducing both heartburn symptoms and esophageal acid exposure, as reflected by the DeMeester score. Methods: Between 1995 and 2000, all patients undergoing laparoscopic Nissen fundoplication (LN) and laparoscopic gastric bypass (LGB) in our practice underwent preoperative and postoperative esophageal physiologic testing. Patients were included in this study that were morbidly obese and had significant heartburn symptoms or objective evidence of acid reflux, and had repeat esophageal physiologic testing after either LN or LGB. Data were obtained through retrospective review of prospectively collected data. Results: Twelve patients met the inclusion criteria: six patients who had LN and six who had LGB. The mean body mass index (BMI) was 55 kg/m² in the LGB group and 39.8 in the LN group. After surgery, the mean DeMeester score decreased from 64.3 to 2.8 in the LN group (p = 0.01) and from 34.7 to 5.7 in the LGB group (p = 0.1). Both groups mean postoperative DeMeester scores were normal after surgery, and there was no significant difference between the two groups (p = 0.3). Both groups experienced a significant improvement in heartburn symptoms postoperatively. The mean preoperative symptom score improved from 3.5 to 0.5 in the LN group (p = 0.01) and from 2.2 to 0.2 in the LGB group (p = 0.003). There was no difference in the mean postoperative symptom scores between the groups (p = 0.35). After surgery, mean LES resting pressures increased from 12.9 to 35.5 (p = 0.003) in the LN group and from 23.6 to 29.7 (p = 0.45) in the LGB group. There were no complications in either group. Conclusion: Results of this study show that laparoscopic gastric bypass and laparoscopic Nissen fundoplication are both effective in treating heartburn symptoms and objective acid reflux in morbidly obese patients. The health benefits of weight loss after laparoscopic gastric bypass should make this operation the procedure of choice in the morbidly obese patient with heartburn.     

Splenic abscess after laparoscopic Nissen fundoplication: a consequence of short gastric vessel division

A 53-year-old male patient underwent a Nissen fundoplication with short gastric vessel (SGV) division for gastroesophageal reflux disease. During the procedure, the upper pole of the spleen was noted to have discrete color changes suggesting ischemia of this area. One month later he presented with a splenic abscess, which required splenectomy. The clinical presentation and management of this case is reported and comments are made on surgical aspects of SGV division during fundoplication to prevent this potentially dangerous situation. Issues such as the surgical management of splenic abscesses, the limitations of laparoscopic splenectomy in these cases, and the risks and benefits of SGV division, are also discussed in this article.     

Laparoscopic Nissen fundoplication without division of short gastric vessels in children

Purpose

It has been suggested that routine division of short gastric vessels (SGVs) results in a more “floppy” Nissen fundoplication leading to improved outcomes, that is, less dysphagia and lower incidences of recurrent gastroesophageal reflux disease (GERD). The aim of this retrospective study was to assess whether laparoscopic Nissen fundoplication without division of SGVs (Rossetti modification) (laparoscopic Nissen-Rossetti fundoplication [LNRF]) is associated with acceptable clinical outcome in children.

Method

The charts of 368 children who underwent LNRF between January 1996 and September 2004 by 1 primary surgeon were retrospectively reviewed. Children were divided into 2 groups: LNRF + gastrostomy (A) and LNRF alone (B). Mean follow-up period of all groups was 4.2 years.

Results

Laparoscopic Nissen-Rossetti fundoplication was completed in 99% (365/368). Mean operating time for group A was 74 minutes and 61 minutes for group B. None in group A required postoperative esophageal dilatation, and 9 in group B (22.5%) required 12 dilatations; 3.6% developed recurrent GERD, 3.7% in group A and 2.5% in group B.

Conclusion

Laparoscopic Nissen-Rossetti fundoplication can be performed with acceptable long-term outcome in children, especially in the majority also requiring chronic gastrostomy access. Short-term, reversible dysphagia may be seen in a small percentage of children having fundoplication alone.     

Variation in fundic dimensions with respect to short gastric vessel division in laparoscopic fundoplication

Background: This study analyzes the geometry involved in laparoscopic fundoplication with respect to short gastric vessel division for the creation of a tension-free Nissen fundoplication. Methods: For fundoplication, the gastric fundus must be long enough to traverse the fixed distance between the right edge of the plication and the highest lateral fixation of the fundus (distance alpha) and to encircle the esophagus (esophageal circumference). We compared these two dimensions to the length of fundus available for fundoplication both before and, when needed, after division of the short gastric vessels. Results: For tension-free Nissen fundoplication, the available fundic length must exceed the sum of the esophageal circumference and the distance alpha. In some patients, exceeding this sum requires division of the short gastric vessels, thereby increasing fundic length. Short gastric vessel division is not necessary in all patients due to significant individual variations in fundic length. Conclusion: There are significant individual variations in fundic length available for fundoplication. The length of the fundus can be increased by dividing short gastric vessels, but it is not always necessary. It is, however, important to take this parameter into consideration when performing the operation in order to avoid postoperative dysphagia.     

Association between persistent symptoms and long-term quality of life after laparoscopic total fundoplication

Background

We investigated which factors are significantly associated with long-term quality of life after laparoscopic total fundoplication in the treatment of gastroesophageal reflux disease.

Methods

Patients (n = 144) were given a standardized frequency-intensity symptoms questionnaire and the Short-Form 36 Health Survey for quality-of-life evaluation before and after laparoscopic total fundoplication.

Results

At follow-up evaluation (n = 102), patients had a significant reduction in their symptoms score and no deterioration in quality of life. A significant association with postoperative dysphagia for solids and/or liquids was found in the physical component summary score of the Short-Form 36 administered to patients postoperatively (P = .003).

Conclusions

In this study, laparoscopic total fundoplication was a safe and effective surgical treatment for gastroesophageal reflux disease, generally offering an improved long-term quality of life, with the exception of a minority of patients (6 of 102 patients; 5.8%) who experienced persistent severe dysphagia.     

Effects of prior endoluminal gastroplication on subsequent laparoscopic Nissen fundoplication

Background The long-term results of endoluminal gastroplication (ELGP) for gastroesophageal reflux disease (GERD) are still under investigation. Laparoscopic Nissen fundoplication (LNF) has unquestionable results in the treatment of GERD and, therefore, it would be unfortunate to compromise this treatment option by performing alternative therapies such as ELGP. Methods Six patients underwent ELGP for the treatment of GERD symptoms. After symptoms returned, these patients elected to have a LNF. Results There was no sign of periesophagitis or intraperitoneal adhesion formation found at hiatal dissection that hindered or complicated the LNF procedure. Recent follow-up has shown that the patient’s GERD symptom scores have decreased, as expected after a de novo LNF. Conclusion ELGP does not alter the surgical dissection or results of a subsequent LNF.     

The respiratory advantage of laparoscopic Nissen fundoplication

Background/purpose

Laparoscopic Nissen fundoplication is replacing the open approach in the treatment of children with gastroesophageal reflux. The postoperative respiratory advantages seem obvious but remain unproven. The authors hypothesized that laparoscopic Nissen fundoplication provides postoperative respiratory advantages in neurologically normal children as well as those with mental retardation or profound neurologic impairment.

Methods

The charts of all laparoscopic Nissen fundoplications over a 4-year period were reviewed. Sixty-one laparoscopic procedures were compared with the most recent 61 consecutive open Nissen fundoplications. The following variables were reviewed: age, weight, gender, preexisting comorbidities, operating time, postoperative pulmonary complications, and length of stay. Categorical data were compared for significance utilizing χ² cross tabulation. Variables representing numerical data were compared by t test.

Results

Although there appeared to be a trend toward sicker patients in the open group, the laparoscopic group showed significantly improved rates of extubation, shorter recovery room stays, shorter durations of chest physiotherapy, fewer intensive care unit admissions, more rapid resumption of baseline feedings, and overall decreased length of stay (P < 0.05). Pulmonary benefits also were noted in the neurologically impaired population when analyzed separately.

Conclusions

Laparoscopic Nissen fundoplication confers a definable benefit with a significant pulmonary advantage in both neurologically normal children and those with neurologic impairment.     

Causes of long-term dysphagia after laparoscopic Nissen fundoplication.

BACKGROUND: Laparoscopic fundoplication has revolutionized the surgical treatment of gastroesophageal reflux disease. Despite improvements in the technique of fundoplication, persistent dysphagia remains a significant cause of postoperative morbidity. METHOD: Causes of persistent postoperative dysphagia were analyzed in a consecutive series of 167 patients after laparoscopic Nissen fundoplication. Short gastric vessel division and its effect on postoperative dysphagia were analyzed. RESULTS: Follow-up was possible in 139 patients (83%). The mean follow-up period was 27 +/- 21 months. Nine patients (6%) had persistent (moderate to severe) dysphagia, and 33 patients (24%) had mild dysphagia. The satisfaction score among patients with persistent dysphagia was significantly lower than that in patients with mild dysphagia (P < 0.0002). On the other hand, the satisfaction rate among patients with mild dysphagia and those who are asymptomatic was similar. Manometry, performed in 7 of 9 persistent dysphagia patients revealed no difference in postoperative lower esophagus sphincter (LES) pressure and relaxation as compared with that in the control group (n = 52). Six of 9 patients with persistent dysphagia underwent a re-do antireflux procedure. Dysphagia as related to fundic mobilization (complete vs. partial) or bougie size (< 58 Fr. vs. > or = 58 Fr.) revealed no difference in the dysphagia ratings. CONCLUSIONS: Laparoscopic short Nissen fundoplication with or without fundic mobilization achieved an acceptable long-term dysphagia rate. Careful patient selection, identification of the short esophagus, and accurate construction of the fundoplication can lead to a decrease in the incidence of persistent postoperative dysphagia.     

Effect of partial and total laparoscopic fundoplication on esophageal body motility

Background Abnormal esophageal body motility often accompanies gastroesophageal reflux disease (GERD). Although the effect of surgery on the pressure and behavior of the lower esophageal sphincter (LES) has been extensively studied, it still is unclear whether a successful fundoplication improves esophageal peristalsis. Methods The pre- and postoperative esophageal manometries of 71 patients who underwent a successful laparoscopic fundoplication (postoperative DeMeester score < 14.7) were reviewed. The patients were grouped according to the type of fundoplication (partial vs total) and preoperative esophageal peristalsis (normal vs abnormal): group A (partial fundoplication and abnormal esophageal peristalsis; n = 16), group B (total fundoplication and normal peristalsis; n = 41), and group C (total fundoplication and abnormal peristalsis; n = 14). Results The LES pressure was increased in all the groups. A significant increase in amplitude of peristalsis was noted in groups A and C. Normalization of peristalsis was achieved in 31% of the group A patients and 86% of the group C patients. No changes occurred in group B. Conclusions Laparoscopic fundoplication increased LES pressure and the strength of esophageal peristalsis in patients with abnormal preoperative esophageal motility. A total fundoplication resulted in normalization of peristalsis in the majority of patients.

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.     

Quality of life before and after laparoscopic Nissen fundoplication

BACKGROUND: Gastroesophageal reflux disease (GERD) is a common disorder in the Western world. The acute disease can usually be managed by medical therapy. To prevent relapse, many patients require lifelong medication. In these patients, laparoscopic antireflux surgery offers a good alternative. The aim of this study was to evaluate the postoperative results and compare pre- and postoperative quality of life after laparoscopic Nissen fundoplication. METHODS: Clinical investigations, including esophageal manometry, pH monitoring, and endoscopy, and a previously validated Quality of Life Index, were performed before and a median of 41 month after antireflux surgery in 75 patients. RESULTS: After laparoscopic Nissen fundoplication, the percentage of total time with pH <4 decreased from 10.4% to 3.2% on 24-h pH monitoring. The mean pressure of the lower esophageal sphincter improved from 8.1 to 12.3 mmHg. Esophagitis healed in 63 of 66 patients in whom it was present prior to surgery. The overall Quality of Life Index improved significantly from 86 +/- 16 to 116 +/- 16. CONCLUSION: Laparoscopic fundoplication provides effective and durable relief of reflux in patients with GERD. The Quality of Life Index showed significant improvement after surgery.     

Medium- and long-term outcome of laparoscopic redo fundoplication

Background For a small subset of patients, laparoscopic fundoplication fails, typically resulting in recurrent reflux or severe dysphagia. Although redo fundoplications can be performed laparoscopically, few studies have examined their long-term efficacy. Methods Using a prospectively maintained database, the authors identified and contacted 41 patients who had undergone redo laparoscopic fundoplications at the University of Washington between 1996 and 2001. The median follow-up period was 50 months (range, 20–95 months). Current symptoms were compared with those acquired and entered into the authors’ database preoperatively. Patients also were asked to return for esophageal manometry and pH testing. Results All redo fundoplications were performed laparoscopically. There were no conversions. The most common indication for redo fundoplication was recurrent reflux. The most common anatomic abnormality was a herniated wrap. Heartburn improved in 61%, regurgitation in 69%, and dysphagia in 74% of the patients. Complete resolution of these symptoms was achieved, respectively, in 45%, 41% and 38% of these same patients. Overall, 68% of the patients rated the success of the procedure as either “excellent” or “good,” and 78% said they were happy they chose to have it. For those who underwent reoperation for gastroesophageal reflux disease, distal esophageal acid exposure according to 24-h pH monitoring decreased after redo fundoplication from 15.7% ± 18.1% to 3.4% ± 3.6% (p = 0.041). Conclusion Although not as successful as primary fundoplication, a majority of patients can expect durable improvement in their symptoms with a laparoscopic redo fundoplication.     

A comparison of laparoscopic and open Nissen fundoplication and gastrostomy placement in the neonatal intensive care unit population

Introduction

The aim of this study was to compare outcomes after laparoscopic and open techniques for Nissen fundoplication and gastrostomy placement in the neonatal intensive care unit (NICU) population.

Methods

The medical records for NICU inpatients who underwent laparoscopic and open Nissen fundoplication and gastrostomy placement from August 2002 to August 2008 were reviewed after Institutional Review Board approval. Each technique was compared with regard to operative time, estimated blood loss, postoperative 24-hour narcotic requirements, time to goal feeds, and complication rates. Analysis of variance was used to determine statistical significance. Data are quoted as mean ± SEM.

Results

Fifty-seven NICU patients underwent fundoplication and gastrostomy placement (25 laparoscopic and 32 open). The time to goal feeds was significantly shorter for the laparoscopic group (4.3 ± 0.4 vs 6.1 ± 0.6 days, P = .04). The 24-hour postoperative narcotic requirement was significantly lower in the laparoscopic group (0.24 ± 0.05 vs 0.55 ± 0.08 mg/kg, P = .007). Operation times (111 ± 5 [open] vs 113 ± 5 minutes, P = .76) and estimated blood loss (13 ± 2 [open] vs 11 ± 1 mL, P = .33) were comparable for both groups.

Conclusion

Laparoscopic and open techniques for Nissen fundoplication with gastrostomy placement are safe and appropriate treatment methods with equivalent operating times for the treatment of gastroesophageal reflux in the NICU population.     

Impact of complete gastric fundus mobilization on outcome after laparoscopic total fundoplication

With the objective of further optimizing the outcome of antireflux surgery, we have studied the importance of dividing the short gastric vessels when performing a laparoscopic total fundoplication. Ninetynine consecutive patients with chronic gastroesophageal reflux disease (GERD) were enrolled in the trial. Forty-seven patients (25 men, age 52 ±1.6 years [mean ± standard error]) were randomized to undergo a laparoscopic Nissen-Rossetti total fundic wrap with intact short gastric vessels, whereas 52 patients (29 men, 48 ±1.4 years) had complete division of these vessels. Quality of life was assessed by means of the psychological general well-being and gastrointestinal symptom rating scale indices. The 6- and 12-month follow-up data are reported. Two patients were converted to open surgery. Mobilization of the fundus significantly prolonged the operative time (120 vs. 104 minutes, P = 0.05); otherwise the complication rates were similar in the two groups. Both procedures were equally effective in controlling gastroesophageal reflux at 6 and 12 months’ postoperatively. Division of the short gastric vessels had no significant impact on the point prevalence of postfundoplication complaints at the given follow-up time points. Quality of life was significantly improved by both operative procedures and remained “normal” throughout the followup period. Dividing all short gastric vessels had no impact on the functional outcome during the first year of recovery after a total laparoscopic fundoplication.

Long-term outcome of laparoscopic Nissen-Rossetti fundoplication for neurologically impaired and normal children

Background This study aimed to assess the long-term effects of laparoscopic Nissen-Rossetti fundoplication (LNF) on clinical and pH evaluations of children with gastroesophageal reflux disease (GERD) according to neurologic status. Methods The study examined 127 children (73 neurologically impaired and 54 neurologically normal with primary GERD) who consecutively underwent LNF from 1992 to 2003. The follow-up protocol included evaluations at 3, 15, and more than 36 months (long-term evaluation) postoperatively, which consisted of physical examination and 24-h pH monitoring. Recurrences were defined as abnormal pH-metry exhibited by symptomatic children. Results The long-term follow-up period averaged 5.5 years. Of the 73 neurologically impaired children, 9 (12%) had GERD recurrences, which occurred during the evaluation period and required redo surgery in four cases, including two Bianchi procedures. In the neurologically normal group, one recurrence (2%) occurred 3 months after surgery. The long-term complications in this group included dyspepsia (n = 3), occasional dysphagia (n = 2), gas bloat syndrome (n = 1), and alimentary disorders (n = 2). Conclusions For children with primary GERD, LNF is a long-term efficient procedure. For the neurologically impaired children, the results were good, with more than 85% of the children symptom free after 5 years, although repeated evaluations are required to diagnose late recurrences related to evolving dysmotility disorders.     

Effects of laparoscopic Nissen fundoplication on esophageal motility

Background This study aimed to evaluate the long-term impact of laparoscopic Nissen fundoplication on esophageal motility in patients with preoperative esophageal dysmotility. Methods This study prospectively followed 580 patients who underwent laparoscopic Nissen fundoplication between 1992 and 1999. Esophageal manometry, 24-h pH monitoring, and symptom score assessment were performed before surgery, then 6 months, 2 years, and 5 years after surgery. Preoperatively, 533 of the patients (93.5%) had normal esophageal contractile pressure (group 1), whereas 38 of the patients (6.5%) had reduced contractile pressure (<30 mmHg) (group 2). Results Esophageal contractile pressures increased significantly in the patients with low preoperative values, whereas it remained unchanged in the patients with normal preoperative contractile pressures. Both groups reported a significant reduction in the dysphagia symptom score after surgery. Conclusion Nissen fundoplication produces a significant long-lasting increase in esophageal contractile pressures in patients with preoperative esophageal dysmotility (i.e., contractile pressure lower than 30 mmHg). Preoperative esophageal dysmotility is therefore not a contraindication to laparoscopic Nissen fundoplication.

Factors contributing to failure of laparoscopic Nissen fundoplication and the predictive value of preoperative assessment

BACKGROUND: Laparoscopic Nissen fundoplication (LNF) has established itself as the procedure of choice in the surgical management of the majority of patients suffering from gastroesophageal reflux disease (GERD). There are, however, few available data on the assessment of long-term failures after LNF. METHODS: We sought to clarify the mechanisms of failure among a group of patients who reported suboptimal results after LNF. In addition, we attempted to identify specific elements in the preoperative evaluation of GERD patients that might herald a predisposition to anatomical or physiological failure. RESULTS: One hundred and thirty-one consecutive patients who underwent LNF by a single surgeon were analyzed to identify reasons for surgical failure. Fourteen patients (10.6%) comprised the failure group. Detailed independent statistical analysis identified a hiatus hernia greater than 3 cm at operation (P = 0.003), abnormal preoperative pH analysis in the upright position (P = 0.039), failure to respond to proton pump inhibition preoperatively (P = 0.015), and a preoperative psychiatric history (P = 0.0012) as predictors of subsequent failure. CONCLUSIONS: In patients who do not respond to proton pump inhibition preoperatively, the evaluating surgeon should be circumspect in advocating antireflux surgery. A detailed assessment of underlying psychiatric or psychological symptoms must also be made. If a large (>3 cm approximately) hiatus hernia is identified or there is abnormal pH analysis in the upright position preoperatively, the surgeon should be guarded about the long-term outcome, and patients should be advised accordingly.     

Examining the learning curve of laparoscopic fundoplications at an urban community hospital

BACKGROUND: Laparoscopic fundoplication for gastroesophageal reflux disease is a procedure associated with specific complications, especially in a surgeon's early experience. The learning curve of this procedure was examined at a tertiary community institution. METHODS: A retrospective review of the first 100 cases performed at Royal Columbian Hospital was conducted. Two surgeons performed the majority of cases and routinely assisted each other. Patients were grouped chronologically with the first 50 cases defined as early institutional experience and a surgeon's first 20 cases defined as early personal experience. RESULTS: Operative time was longer in both the early institutional (117.8 versus 91.3 minutes, P < .001) and personal experience (126.8 versus 89.7 minutes, P < .001). The rate of dysphagia requiring intervention was higher during the early institutional (22% versus 4%, P = .017) but not personal experience (19% versus 8%, P = not significant). The conversion rate was 0%, reoperation rate was 1%, mean length of stay was 2.5 +/- 1.4 days, and the readmission rate was 5%; these outcomes were unaffected by the learning curve. CONCLUSIONS: There is a definable learning curve in laparoscopic fundoplication in terms of operative time. However, an acceleration of the personal learning curve in terms of dysphagia was observed with a two-surgeon collaborative approach. With careful patient selection conversion, reoperation, readmission, and complication rates equivalent to experienced centers can be achieved in the community setting early in the personal and institutional experience.
