Laparoscopic repair of large hiatal hernia with polytetrafluoroethylene

Background: Several studies have shown that large hiatal hernias are associated with a high recurrence rate. Despite the problem of recurrence, the technique of hiatal herniorrhaphy has not changed appreciably since its inception. In this 3-year study we have evaluated laparoscopic hiatal hernia repair in individuals with a hernia defect greater than 8 cm in diameter. Methods: A series of 35 patients with sliding or paraesophageal hiatal hernias was prospectively randomized to hiatal hernia repair with (n= 17) or without (n= 18) polytetrafluoroethylene (PTFE). All patients had an endoscopic and radiographic diagnosis of large hiatal hernia. Both repairs were performed by using interrupted stitches to approximate the crurae. In the group randomized to repair with prosthesis, PTFE mesh with a 3-cm ``keyhole' was positioned around the gastroesophageal junction with the esophagus through the keyhole. The PTFE was stapled to the diaphragm and crura with a hernia stapler. Results: Patients were followed with EGD and esophagogram at 3 months postoperatively, and with esophagogram every 6 months thereafter. Individuals with PTFE had a longer operation time, but the 2-day hospital stay was the same in both groups. The cost of the repair was $1050 ± $135 more in the group with the prosthesis. There were two complications (1 pneumonia, 1 urinary retention) in the group repaired with PTFE and one complication (pneumothorax) in the group without prosthesis. The group without PTFE was notable for three (16.7%) recurrences within the first 6 months of surgery. Conclusion: On the basis of these preliminary results it appears that repair with PTFE may confer an advantage, with lower rates of recurrence in patients with large hiatal hernia defects.

Nissen-type fundoplication and its effects on the emetic reflex and gastric motility in the ferret

Recurrent vomiting with failure to thrive is a common problem in neurologically impaired children. Many undergo fundoplication to control the underlying gastro-oesophageal reflux. The results of surgery are not always satisfactory and post-operative retching may be a major problem - a symptom indicative of activation of the emetic reflex. An animal model of antireflux surgery has been developed and used to investigate the effects of such surgery upon the emetic reflex and vagal influences on gastric motility. Following surgery, animals responded to a previously subemetic dose of a centrally acting opiate receptor agonist (loperamide), suggesting that fundoplication may sensitize the emetic reflex. A gastric vago-vagal reflex (tonic inhibition of corpus tone) and responses to direct stimulation of vagal motor efferents (both cholinergic and nonadrenergic noncholinergic responses) were not significantly affected by antireflux surgery. Mechanisms by which neural damage may sensitize the emetic reflex are discussed, together with the possible clinical implications for the management of post-operative symptoms in neurologically impaired children.

Trends and perioperative outcomes of inpatient antireflux surgery in the United States, 1993–2006

Antireflux surgery is an effective treatment for gastroesophageal reflux disease, but postoperation complications and durability may be problematic. The objective of the study was to determine whether inpatient antireflux surgery continued to decline in the United States due to concerns about its long‐term effectiveness and the popularity of gastric bypass surgery and to assess recent changes in its perioperative outcomes. Using the Nationwide Inpatient Sample, we identified adult patients undergoing inpatient antireflux surgery during 1993–2006 and compared the trends of inpatient antireflux surgery with inpatient gastric bypass surgery. Perioperative complications included laceration, splenectomy, transfusion, esophageal dilation, total parenteral nutrition, and infection. Inpatient antireflux surgery increased from 9173 in 1993 to 32 980 in 2000 (+260%) but then decreased to 19 668 in 2006 (?40%). Compared with 2000, patients undergoing inpatient antireflux surgery in 2006 were older (49.9 ± 32.4 vs. 54.6 ± 33.6 years) and had a longer length of stay (3.1 ± 10.0 vs. 3.7 ± 13.4 days), more complications (4.7% vs. 6.1%), and higher mortality (0.26% vs. 0.54%) (all P < 0.05). Compared with inpatient gastric bypass surgery, length of stay was longer and mortality was higher for inpatient antireflux surgery in 2006, but neither was significant controlling for age. In 2006, perioperative outcomes of inpatient antireflux surgery were better in high‐volume hospitals (all P < 0.01). Inpatient antireflux surgery continued to decline in the United States from 2000 to 2006, concomitant with a dramatic increase in inpatient gastric bypass surgery. Older patient age and worsening perioperative outcomes for inpatient antireflux surgery suggest increased medical complexity and possibly a larger share of reoperations over time. Designating centers of excellence for antireflux surgery based on local expertise may improve outcomes.     

Impact of Laparoscopic Nissen Fundoplication on Non-complicated Barrett��s Esophagus

Background/Aim:

Laparoscopic fundoplication can alter the natural course of Barrett’s esophagus (BE). This study was undertaken to assess this role in patients with non-complicated BE.

Materials and Methods:

From October 2004 to October 2009, 43 patients with BE (32 men and 11 women) underwent laparoscopic Nissen fundoplication surgery in the Department of Surgery at Minia University Hospital. The median age of these patients was 46 years (range: 22–68 years). Patients with high-grade dysplasia, invasive cancer, or previous antireflux surgery were excluded. All 43 patients had gastroesophageal reflux symptoms. Heartburn was present in all patients, regurgitation in 41 (95.3%), dysphagia in 8 (18.6%), retrosternal pain in 30 (69.8%), upper gastrointestinal hemorrhage in 6 (13.9%), and respiratory symptoms in 19 (44.2%). Nissen fundoplication was performed in all patients. Thirty-four patients (79.1%) had concomitant hiatal hernia and nine patients (20.9%) had low-grade dysplasia.

Results:

The median follow-up period was 25.6 months. There was significant improvement of symptoms after surgery (P<0.05). Eight (18.6%) of those with short-segment BE had total regression and four (9.3%) of those with long-segment BE had a decrease in total length. Among the nine patients with preoperative low-grade dysplasia, dysplasia disappeared in seven, remained unchanged in one, and progressed to in situ adenocarcinoma in one patient.

Conclusions:

laparoscopic fundoplication succeeded in controlling symptoms but had unpredictable effect on dysplasia and regression of BE. Laparoscopic fundoplication does not eliminate the risk of developing esophageal adenocarcinoma and therefore, endoscopic follow-up should be continued in these patients.

Revision of failed transoral incisionless fundoplication by subsequent laparoscopic Nissen fundoplication

AIM:To evaluate the feasibility and outcomes of laparoscopic Nissen fundoplication after failed transoral incisionless fundoplication(TIF).METHODS:TIF is a new endoscopic approach for treating gastroesophageal reflux disease(GERD).In cases of TIF failure,subsequent laparoscopic fundoplication may be required.All patients from 2010 to 2013 who had persistence and objective evidence of recurrent GERD after TIF underwent laparoscopic Nissen fundoplication.Primary outcome measures included operative time,blood loss,length of hospital stay and complications encountered.RESULTS:A total of 5 patients underwent revisional laparoscopic Nissen fundoplication(LNF)or gastrojejunostomy for recurrent GERD at a median interval of 24mo(range:16-34 mo)after TIF.Patients had recurrent reflux symptoms at an average of 1 mo following TIF(range:1-9 mo).Average operative time for revisionalsurgical intervention was 127 min(range:65-240 min)and all surgeries were performed with a minimal blood loss(<50 m L).There were no cases of gastric or esophageal perforation.Three patients had additional finding of a significant hiatal hernia that was fixed simultaneously.Median length of hospitalization was 2 d(range:1-3 d).All patients had resolution of symptoms at the last follow up.CONCLUSION:LNF is a feasible and safe option in a patient who has persistent GERD after a TIF.Previous TIF did not result in additional operative morbidity.     

Development of achalasia secondary to laparoscopic Nissen fundoplication

Dysphagia after laparoscopic Nissen fundoplication (LNF) is commonly attributed to edema and/or improperly constructed wraps, and in some instances the cause can be difficult to identify. We report, for the first time, the development of secondary achalasia after LNF as a cause of late-onset postoperative dysphagia. A total of 250 consecutive patients undergoing LNF were analyzed for the development of postoperative dysphagia at a university hospital. Patients were considered to have secondary achalasia if they met the following four criteria: (1) preoperative manometry demonstrating normal peristalsis and normal lower esophageal sphincter (LES) relaxation; (2) lack of esophageal peristalsis on postoperative manometry or fluoroscopy with or without incomplete LES relaxation; (3) no mucosal lesions seen on endoscopy; and (4) dysphagia refractory to dilatation. The following three groups of patients were identified: patients who developed secondary achalasia (group A, n = 7); patients with persistent dysphagia requiring and responding to postoperative dilatation (group B, n = 12 patients); and patients whose postoperative recovery was not complicated by dysphagia (group C, n = 231). The groups were comparable in terms of all preoperative variables except for age. Patients in group A were older than those in group B (57 years [range 27 to 66 years] vs. 36.5 years [range 27 to 63 years], P = 0.028) but were not significantly older than patients in group C (45 years [range 20 to 84 years], P = 0.42). The onset of severe dysphagia was later in group Athan in group B (135 days [range 15 to 300 days] vs. 20 days [range 9 to 70 days],P = 0.002). The median weight loss in group A was also significantly greater than in Group B (15 pounds [range 11 to 44 pounds] vs. 4 pounds [range 0 to 15 pounds], P = 0.0007). Two patients in group A who underwent reoperation failed to improve. Botulinum toxin injections were tried in two patients and Heller myotomy in one with good results. Nine patients in group B improved promptly after one dilatation, and three improved after two dilatations. Secondary achalasia should be considered as one of the causes of persistent dysphagia after an apparently successful antireflux operation. Secondary achalasia tends to occur in older patients and is characterized by a delayed onset of symptoms. Imaging studies are a reliable means of excluding mechanical obstruction as a cause of secondary achalasia, and a negative result should raise the suspicion of secondary achalasia. Esophageal motility studies are necessary to confirm the diagnosis. Failure to consider the diagnosis of secondary achalasia can lead to multiple fruitless attempts at dilatation or even inappropriate reoperations.
