Efficacy and feasibility of laparoscopic redo fundoplication

Magnetic challenge against gastroesophageal reflux

Almost 15 years have passed since the first paper on the possibility of using magnets to prevent gastro-esophageal reflux (GER) was published and so it is time to assess the results obtained with the first magnetic device available on the market, the Linx magnetic sphincter augmentation (MSA) and to consider what other options are forthcoming. MSA demonstrated an anti-reflux activity similar to that of Nissen fundoplication, considered the "gold standard" surgical treatment for GER disease, and caused less gas-bloating and a better ability to allow vomiting and belching. However, unlike Nissen fundoplication, this magnetic device is burdened by complications, which are roughly similar to those of the non-magnetic anti-reflux Angelchik prosthesis, that, after considerable use in the eighties, was shelved due to these complications. It is interesting to note that some of these complications show the same pathophysiological mechanism in both devices. The upcoming new magnetic devices should avoid these complications, as their anti-reflux magnetic mechanism is completely different. The experiments in animals regarding these new magnetic appliances were examined, remarking their advantages and drawbacks, but the way to apply them in surgical practice is long and difficult, although worthy, as they represent the future of magnetic surgery.

The Collis Procedure and the Acquired Short Esophagus

One of the most intriguing problems in modern esophageal surgery is the acquired short esophagus. While some authors recognize this entity, others deny its existence. There is a consensus about types of the short esophagus, its etiology and pathophysiology. Definitive diagnosis can be established only intraoperatively. There are a few surgical procedures for this problem, and most frequently is used Collis gastroplasty with fundoplication. In this review we emphasize recent literature data and further perspectives of the Collis procedure.

Role of fundoplication in treatment of patients with symptoms of hiatal hernia

Gastroesophageal reflux disease (GERD) is often associated with hiatal hernia (HH). However, the need for fundoplication during hiatal hernia repair (HHR) remains controversial. The objective of this study was to evaluate the effect of HHR with concomitant laparoscopic Nissen fundoplication (HHR-LNF) in HH patients. A total of 122 patients with symptomatic HH were randomized to receive either HHR (n = 61) or HHR-LNF (n = 61). The measures of evaluating outcomes included DeMeester scores (DMS), complications, Reflux Diagnostic Questionnaire and patients' satisfaction 24 months following surgery. Despite comparable values in both groups at randomization, the DMS, total numbers of reflux episodes and percentage of time with pH < 4 were significantly higher in HHR group than in HHR-LNF group (P = 0.017, P = 0.002 and P = 0.019, respectively) at 6 months after surgery. One months postoperatively, complications were higher in the HHR-LNF group than in the HHR group (all P < 0.001), and there was no difference between the two groups at 6 months. By the end of the 2-year follow-up, HHR-LNF group showed a significantly lower reflux syndrome frequency-intensity score and greater percentage of satisfaction compared with HHR group (all P < 0.001). Laparoscopic HHR should be combined with a fundoplication in GERD patients with HH. HHR-LNF is safe and effective, not only improve reflux-related symptom, but also reduce the incidence of complications.

A Comparison of Laparoscopic Redo Fundoplications for Failed Toupet and Nissen Fundoplications in Children

Purpose:

We compared laparoscopic redo fundoplications performed for failed laparoscopic Toupet fundoplication (LTF) and failed laparoscopic Nissen fundoplications (LNFs).

Methods:

Redo LTF (R-LTF; n = 4) and redo LNF (R-LNF; n = 6) performed between 2007 and 2014 were assessed retrospectively for severity of intraperitoneal adhesions on a scale of 0–3, identification/preservation of the anterior/posterior/hepatic branches of the vagus nerve (VN), complications, and outcome.

Results:

Redos were performed after a mean of 34 months in R-LTF and 32 months in R-LNF (P = ns) indicated for sliding hernia (n = 3; 2 with partial wrap dehiscence) and partial wrap dehiscence (n = 1) in R-LTF and sliding hernia (n = 6; 4 with partial wrap dehiscence) in R-LNF. The mean adhesion severity score was 1.5 in R-LTF and 2.5 in R-LNF (P < 0.05). The mean number of VN branches identified/preserved was 2.0 in R-LTF and 0.8 in R-LNF (P < 0.05). Mean operative times and mean blood loss were similar. Intraoperative complications were accidental local trauma (n = 1 in R-LTF and n = 3 in R-LNF, one requiring conversion to open repair) (P = ns). Gastric outlet obstruction developed in two R-LNF cases; both were managed conservatively. There have been no further recurrences to date.

Conclusion:

Although our series is small, adhesions were less, and identification/preservation of VN was easier during R-LTF.

Complications of Antireflux Surgery

Antireflux surgery anatomically restores the antireflux barrier and is a therapeutic option for proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease or PPI intolerance. Laparoscopic fundoplication is the standard antireflux surgery, though its popularity has declined due to concerns regarding wrap durability and adverse events. As the esophagogastric junction is an anatomically complex and dynamic area subject to mechanical stress, wraps are susceptible to disruption, herniation or slippage. Additionally, recreating an antireflux barrier to balance bidirectional bolus flow is challenging, and wraps may be too tight or too loose. Given these complexities it is not surprising that post-fundoplication symptoms and complications are common. Perioperative mortality rates range from 0.1 to 0.2% and prolonged structural complications occur in up to 30% of cases. Upper gastrointestinal endoscopy with a comprehensive retroflexed examination of the fundoplication and barium esophagram are the primary tests to assess for structural complications. Management hinges on differentiating complications that can be managed with medical and lifestyle optimization versus those that require surgical revision. Reoperation is best reserved for severe structural abnormalities and troublesome symptoms despite medical and endoscopic therapy given its increased morbidity and mortality. Though further data are needed, magnetic sphincter augmentation may be a safer alternative to fundoplication.

Primary and Redo Antireflux Surgery: Outcomes and Lessons Learned

INTRODUCTION

Some patients require one or more reoperative interventions after undergoing primary antireflux surgery (ARS). We compared outcomes after primary and reoperative ARS.

METHODS

We queried a prospectively maintained database to identify patients who underwent ARS from September 23, 2003 to May 28, 2016. Patients were categorized into four groups: A (primary ARS), B (first reoperative ARS), C (second reoperative ARS), or D (≥ third reoperative ARS). Patients completed follow-up foregut symptom surveys and satisfaction questionnaires at regular intervals.

RESULTS

In total, 940 patients were studied (A: n = 545, B: n = 302, C: n = 80, D: n = 13). Age, sex, and BMI were comparable across groups. Heartburn was the most common preoperative symptom in A, whereas dysphagia was more common in B-D. Open approach, mean operative time, and mean blood loss increased from A to D (P < 0.05), as did need for Roux-en-Y reconstruction. Vagal injury (2-19-33-54%; P < 0.05), visceral perforation (2-20-36-23%; P < 0.05), postoperative leak (0.2-2-6-8%; P < 0.05 A vs. all), and morbidity (2-10-14-39%; P < 0.05) also increased from A to D. At mean follow-up of 36 months, the proportion of patients who reported no significant symptoms, excellent satisfaction, and likeliness to recommend this surgery to a friend progressively declined with each successive reintervention (P < 0.05).

CONCLUSIONS

Complications and patient-reported outcomes worsen with each reoperative ARS.

Endoscopic clipping of the Z-line (CMZL) helps recognize anatomical failures after Nissen fundoplication: technical report of a new method

Introduction

Nearly 15% of patients after laparoscopic antireflux surgery experience recurrence of symptoms or develop new gastrointestinal symptoms. Some of them require redo procedures. It can be demanding to reveal anatomical failure after previous fundoplication.

Aim

To present a method which assists in recognition of anatomical failures after Nissen fundoplication.

Material and methods

Five patients with previous laparoscopic Nissen fundoplication and severe gastrointestinal symptoms were included in this study. During the esophagogastroduodenoscopy (EGDS) two radiopaque metal clips were placed to mark the Z-line (“clips-marked Z-line” – CMZL). It was done to achieve precise visualization of the gastroesophageal junction area in the video contrast investigation. Distinctions between conclusions after the EGDS, ordinary video contrast investigation, video contrast investigation with CMZL and intraoperative findings were analyzed.

Results

All patients underwent laparoscopic refundoplication with good postoperative results. There were 4 cases misdiagnosed by contrast investigation without clips and four cases misdiagnosed by EGDS. Endoscopic clipping helped to recognize correctly all anatomical failures.

Conclusions

Applying CMZL as a routine investigation before redo fundoplication can reduce frequency of misdiagnosis and help to perform redo fundoplication in appropriate patients, but it requires further studies on larger cohorts of patients.

Current readings: Failed hiatal hernia repair

Recurrent hiatal hernia is noted in up to 70% of patients undergoing reoperative antireflux procedure. Role of short esophagus vis-à-vis a need for Collis gastroplasty, mesh reinforcement of hiatus, and access of surgery (thoracotomy vs laparotomy) have been debated. The aim of this article is to review selected recent publications that address these issues.
