Management of esophageal symptoms following fundoplication

Postoperative problems 2011: fundoplication and obesity surgery

Although the surgical treatment of both GERD and obesity is very successful, these procedures have a significant impact on the physiology and function of the proximal GI tract. With the increasing prevalence of both GERD and obesity, more and more patients present at the motility outpatient clinic with symptoms related to surgical interventions for these medical problems. In this review, we describe the main complications following antireflux surgery: dysphagia, gas bloat syndrome, recurrent (persistent) GERD symptoms, and dyspeptic symptoms. The most common motility-related complications of obesity surgery are dumping syndrome and esophageal dysmotility.

Dysphagia after laparoscopic Nissen fundoplication

OBJECTIVE

To investigate the frequency and severity of dysphagia during the first 8 weeks after laparoscopic Nissen fundoplication for gastro-oesophageal reflux disease. So far, there have been no studies reporting data on day-to-day occurrence of dysphagia after laparoscopic fundoplication in a consecutive series of patients. This may explain why the frequency of dysphagia varies greatly in the literature (4-100%).

MATERIAL AND METHODS

Forty consecutive patients, undergoing elective laparoscopic Nissen fundoplication, completed a standard dysphagia registration diary each day during the first 8 weeks after surgery. Patients who preoperatively had suffered from dysphagia were excluded. Thus, none of the patients had dysphagia in the 2-month period before surgery. Ten patients undergoing elective cholecystectomy served as controls. Data were quantified, and a score value of 4 or more was considered bothersome.

RESULTS

Thirty-seven patients (93%) experienced some degree of dysphagia during the observation period. Sixteen patients (44%) had at least one day with annoying dysphagia. The dysphagia started 1-2 days after surgery, was most prominent during the first few weeks, and subsided in nearly all cases after 5-6 weeks. Two patients with persistent dysphagia were treated once with balloon dilatation. None of the patients in the control group had dysphagia.

CONCLUSIONS

Nearly all patients experience some degree of dysphagia after laparoscopic Nissen fundoplication, and in nearly half of the patients it is considered annoying. However, even severe dysphagia usually disappears within 5-6 weeks. These results suggest a conservative attitude for the first 1-2 months after surgery. The data may also serve as a background for preoperative information to the patients.

Altered esophageal sensory-motor function in patients with persistent symptoms after Nissen fundoplication

BACKGROUND

The pathophysiology of persistent gastroesophageal reflux disease (GERD) symptoms after antireflux surgery is unclear. We assessed esophageal sensorimotor function in patients with GERD before and after Nissen fundoplication (NF).

METHODS

Sensory and biomechanical properties were evaluated before surgery using impedance planimetry in 17 GERD patients and 16 healthy volunteers. All patients underwent standard laparoscopic NF. Eight GERD patients with persistent symptoms after surgery underwent repeat evaluations at least 12 months after surgery.

RESULTS

At baseline, GERD patients had lower thresholds for first perception (P < .001), discomfort (P < .001), and pain (P < .001) compared with controls. The esophagus was more reactive (P = .001) and less distensible (P = .04) in patients than controls. After NF, in patients with persistent symptoms, the sensory thresholds were unchanged (P > .05) but esophageal wall reactivity decreased (P = .001), and distensibility improved (P = .025).

CONCLUSIONS

NF improves esophageal biomechanical dysfunction but not the underlying hypersensitivity. Visceral hypersensitivity of the esophagus may explain persistent symptoms after NF.
