LATE EVALUATION OF PATIENTS OPERATED FOR GASTROESOPHAGEAL REFLUX DISEASE BY NISSEN FUNDOPLICATION

Background:

Surgical treatment of GERD by Nissen fundoplication is effective and safe, providing good results in the control of the disease. However, some authors have questioned the efficacy of this procedure and few studies on the long-term outcomes are available in the literature, especially in Brazil.

Aim:

To evaluate patients operated for gastro-esophageal reflux disease, for at least 10 years, by Nissen fundoplication.

Methods:

Thirty-two patients were interviewed and underwent upper digestive endoscopy, esophageal manometry, 24 h pH monitoring and barium esophagogram, before and after Nissen fundoplication.

Results:

Most patients were asymptomatic, satisfied with the result of surgery (87.5%) 10 years after operation, due to better symptom control compared with preoperative and, would do it again (84.38%). However, 62.5% were in use of some type of anti-reflux drugs. The manometry revealed lower esophageal sphincter with a mean pressure of 11.7 cm H₂O and an average length of 2.85 cm. The average DeMeester index in pH monitoring was 11.47. The endoscopy revealed that most patients had a normal result (58.06%) or mild esophagitis (35.48%). Barium swallow revealed mild esophageal dilatation in 25,80% and hiatal hernia in 12.9% of cases.

Conclusion:

After at least a decade, most patients were satisfied with the operation, asymptomatic or had milder symptoms of GERD, being better and with easier control, compared to the preoperative period. Nevertheless, a considerable percentage still employed anti-reflux medications.

Heller myotomy with esophageal diverticulectomy: an operation in need of improvement

BACKGROUND

This study was undertaken to evaluate the outcomes after laparoscopic Heller myotomy with anterior fundoplication and diverticulectomy for patients with achalasia and esophageal diverticula.

METHODS

634 patients undergoing laparoscopic Heller myotomy and anterior fundoplication from 1992 to 2015 are prospectively followed up; patients were stratified for those undergoing concomitant diverticulectomy. Patients graded symptom frequency and severity before and after myotomy, using a Likert scale (0 = never/not bothersome to 10 = always/very bothersome). Median data are presented (mean ± SD).

RESULTS

Forty-four patients, age 70 years (65 ± 14.2), underwent laparoscopic Heller myotomy, anterior fundoplication, and diverticulectomy. Operative time was 182 min (183 ± 54.6). Fifty percentage of patients had a postoperative complication: Most notable were leaks at the diverticulectomy site (n = 8) and pulmonary complications (n = 11; 10 effusion, 1 empyema). Length of stay (LOS) was 3 days (5 ± 8.3). All leaks occurred after discharge and resolved without sequelae using transthoracic catheter drainage and parenteral nutrition; two patients received endoscopic esophageal stents. Median follow-up is 39 months. Symptoms amelioration was significant postoperatively, including severity of dysphagia [6 (6 ± 3.9) to 2(4 ± 3.6)]. Seventy-six percentage of patients rated their symptoms at last follow-up as satisfying/very satisfying. Seventy-seven percentage of patients had symptoms once per week or less. Eighty-one percentage would have the operation again knowing what they know now.

CONCLUSIONS

Laparoscopic Heller myotomy, anterior fundoplication, and diverticulectomy well palliate the symptoms of achalasia with accompanying esophageal diverticulum. The operations are generally longer than those without diverticulectomy and are accompanied by a relatively longer LOS. Complications are relatively frequent and severe (e.g., leaks and pneumonia). In particular, leaks at the diverticulectomy site are unpredictable, occur after discharge, and remain vexing. Nevertheless, for this advanced form of achalasia, long-term symptom relief and patient satisfaction are high after anterior fundoplication with concomitant diverticulectomy. New and innovative techniques are needed to decrease the frequency of leaks at the diverticulectomy site.

A Single Institutions First 100 Patients Undergoing Laparoscopic Anti-Reflux Fundoplications: Where are They 20 Years Later?

Although anti-reflux surgery has been used liberally over the past decades for the treatment of gastroesophageal reflux disease (GERD), few studies report follow-up after 10 years. This study was undertaken to report follow-up on 100 consecutive GERD patients up to 22 years after utilizing a laparoscopic fundoplication. Hundred consecutive patients undergoing laparoscopic fundoplication for GERD were prospectively followed beginning in 1992. The frequency and severity of symptoms before and after laparoscopic fundoplication were scored on a Likert scale (1 = never/none to 10 = always/very bothersome). Median data are reported. Of the 100 patients who underwent laparoscopic fundoplication for their GERD, nine were reoperations. Twenty-six patients are deceased on average 11 years after their fundoplications. Seventy-four patients are alive, with 27 patients, actively followed for 19 years after their fundoplications. At most recent follow-up, patients experienced long-term amelioration of symptom frequency and severity after fundoplication (e.g., heartburn frequency = 8–2, severity = 8–1; P < 0.01 for each). Eighty-four per cent of patients rated their symptom frequency as less than once per month. Eighty-eight per cent of patients were satisfied with their postoperative results, and 95 per cent of patients confirmed they would have the operation again knowing what they know now. Long-term follow-up documents high patient satisfaction and durable symptomatic relief up to two decades after laparoscopic fundoplication for GERD. Patients should seek this operation not only for symptomatic relief, but to mitigate the deleterious effects of long-term acid exposure and anti-acid therapy.

Does the cost of robotic cholecystectomy translate to a financial burden?

INTRODUCTION

Robotic application to cholecystectomy has dramatically increased, though its impact on cost of care and reimbursement has not been elucidated. We undertook this study to evaluate and compare cost of care and reimbursement with robotic versus laparoscopic cholecystectomy.

METHODS AND PROCEDURES

The charges and reimbursement of all robotic and laparoscopic cholecystectomies at one hospital undertaken from June 2012 to June 2013 were determined. Operative duration is defined as time into and time out of the operating room. Data are presented as median data. Comparisons were undertaken using the Mann-Whitney U-test with significance accepted at p ≤ 0.05.

RESULTS

Robotic cholecystectomy took longer (47 min longer) and had greater charges ($8,182.57 greater) than laparoscopic cholecystectomy (p < 0.05 for each). However, revenue, earnings before depreciation, interest, and taxes (EBDIT), and Net Income were not impacted by approach.

CONCLUSIONS

Relative to laparoscopic cholecystectomy, robotic cholecystectomy takes longer and has greater charges. Revenue, EBDIT, and Net Income are similar after either approach; this indicates that costs with either approach are similar. Notably, this is possible because much of hospital-based costs are determined by cost allocation and not cost accounting. Thus, the cost of longer operations and costs inherent to the robotic approach for cholecystectomy do not translate to a perceived financial burden.

Transoral Incisionless Fundoplication: Is it as Safe and Efficacious as a Nissen or Toupet Fundoplication?

Transoral incisionless fundoplication (TIF) was U.S. Food and Drug Administration-approved in 2007 to treat gastroesophageal reflux disease (GERD), but comparative data are lacking. This study was undertaken to compare outcomes for patients with GERD undergoing TIF versus laparoscopic Nissen or Toupet fundoplications. We undertook a case-controlled study of three cohorts of 20 patients undergoing TIF or laparoscopic Nissen or Toupet fundoplications from 2010 to 2013 controlling for age, body mass index, and preoperative DeMeester scores. All patients were pro-spectively followed. Median data are reported. Patients undergoing TIF had significantly shorter operative times (in minutes: 71 vs 119 and 85, respectively, P < 0.001) and length of stay (in days: 1, 2, and 1, respectively, P < 0.001). No matter the approach, patients reported dramatic and similar reduction in symptom frequency and severity (e.g., heartburn 8 to 0, P < 0.05). At follow-up, 83 per cent of patients after TIF, 80 per cent after Nissen, or 92 per cent after Toupet fundoplications had symptoms less than once per month ( P = 0.12). TIF leads to dramatic symptom resolution, similar when compared with Nissen or Toupet fundoplications. TIF promotes shorter operative times and lengths of stay. Patient satisfaction and effective palliation of symptoms show that TIF is safe and efficacious in comparison to Nissen and Toupet fundoplications and support its continued application and evaluation.

Identification of preoperative risk factors for persistent postoperative dysphagia after laparoscopic antireflux surgery

BACKGROUND

Postoperative dysphagia is common after antireflux surgery and generally runs a self-limiting course. Nevertheless, part of these patients report long-term dysphagia. Inadequate surgical technique is a well documented cause of this result.

AIM

This retrospective study evaluated the preoperative risk factors not surgery-related for persistent dysphagia after primary laparoscopic antireflux surgery.

METHODS

Patients who underwent laparoscopic antireflux surgery by the modified technique of Nissen were evaluated in the preoperative period retrospectively. Postoperative severity of dysphagia was evaluated prospectively using a stantardized scale. Dysphagia after six weeks were defined as persistent. Statistical tests of association and logistic regression were used to identify risk factors associated with persistent dysphagia.

RESULTS

A total of 55 patients underwent primary antireflux surgery by a single surgeon team. Of these, 25 patients had preoperative dysphagia (45,45%). Persistent postoperaive dysphagia was reported by 20 (36,36%). Ten patients (18,18%) required postoperative endoscopic dilatation for dysphagia. There was statistical association between satisfaction with surgery and postoperative dysphagia and requiring the use of antireflux medication after the procedure; and between preoperative dysphagia and postoperative dysphagia. Logistic regression identified significant preopertive dysphagia as risk factor for persistent postoperative dysphagia. No correlations were found with preoperative manometry.

CONCLUSIONS

Patients with significant preoperative dysphagia were more likely to report persistent postoperative dysphagia. This study confirms that the current manometric criteria used to define esophageal dysmotility are not reliable to identify patients at risk for post-fundoplication dysphagia. Minucious review of the clinical history about the presence and intensity of preoperative dysphagia is important in the selection of candidates for antireflux surgery.
