Laparoscopic Nissen versus Toupet fundoplication: assessment of operative outcomes

Prevalence and severity of abdominal bloating in patients with gastroesophageal reflux disease

Abdominal bloating (AB) is a common symptom among patients with gastroesophageal reflux disease (GERD); however, in clinical practice, its prevalence is likely underestimated due to the lack of objective tools to measure its frequency and severity. It is associated with dissatisfaction and worse quality of life, but data on its prevalence before and after mechanical control of GERD (i.e. fundoplication, magnetic sphincter augmentation, and antireflux mucosectomy) are lacking. To assess and determine the pre- and postoperative prevalence and severity of AB among patients with GERD, we conducted a structured literature search using MeSH and free-text terms in MEDLINE (via Pubmed), EMBASE, and Taylor & Francis Online between January 1977 and October 2022. Fifteen articles reporting the prevalence or severity of AB using quality-of-life questionnaires before or after antireflux surgery (ARS) were included. Overall, a high prevalence of AB before ARS was found. A decline in the prevalence and severity of AB was documented postoperatively in most cases independent of the surgical approach. Among surgical approaches, a complete fundoplication had the highest reported postoperative AB. Overall, patients reported less severe and less frequent AB after ARS than before. The traditional belief that postoperative bloating is a sequela of ARS should be reevaluated.

Nissen Versus Toupet Fundoplication For Gastro-oesophageal Reflux Disease, Short And Long-term Outcomes. A Systematic Review And Meta-analysis

BACKGROUND

Gastroesophageal reflux disease (GERD) remains one of the most commonly encountered gastrointestinal disorders. Proton pump inhibitors still show an inadequate effect on about 10% to 40% of the patients. Laparoscopic antireflux surgery is the surgical alternative for managing GERD in patients who are not responding to proton pump inhibitors.

AIM OF THE STUDY

This study objected at comparing laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication (LTF) concerning the short-term and long-term outcomes.

PATIENTS AND METHODS

This is a systematic review and meta-analysis that evaluated the studies comparing between Nissen fundoplication and LTF for the treatment of GERD. Studies were obtained by searching on the EMBASE, the Cochrane Central Register of Controlled Trials, and PubMed central database.

RESULTS

The LTF group showed significantly longer operation time, less postoperative dysphagia and gas bloating, less pressure on the lower esophageal sphincter, and higher Demeester scores. No statistically significant differences were found between the 2 groups in the perioperative complications, the recurrence of GERD, the reoperation rate, the quality of life, or the reoperation rate.

CONCLUSION

LTF is favored for the surgical treatment of GERD being of lower postoperative dysphagia and gas bloating rates. These benefits were not at the expense of significantly additional perioperative complications or surgery failure.

Multi-society consensus conference and guideline on the treatment of gastroesophageal reflux disease (GERD)

BACKGROUND

Gastroesophageal reflux disease (GERD) is one of the most common diseases in North America and globally. The aim of this guideline is to provide evidence-based recommendations regarding the most utilized and available endoscopic and surgical treatments for GERD.

METHODS

Systematic literature reviews were conducted for 4 key questions regarding the surgical and endoscopic treatments for GERD in adults: preoperative evaluation, endoscopic vs surgical or medical treatment, complete vs partial fundoplication, and treatment for obesity (body mass index [BMI] ≥ 35 kg/m²) and concomitant GERD. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Recommendations for future research were also proposed.

RESULTS

The consensus provided 13 recommendations. Through the development of these evidence-based recommendations, an algorithm was proposed for aid in the treatment of GERD. Patients with typical symptoms should undergo upper endoscopy, manometry, and pH-testing; additional testing may be required for patients with atypical or extra-esophageal symptoms. Patients with normal or abnormal findings on manometry should consider undergoing partial fundoplication. Magnetic sphincter augmentation or fundoplication are appropriate surgical procedures for adults with GERD. For patients who wish to avoid surgery, the Stretta procedure and transoral incisionless fundoplication (TIF 2.0) were found to have better outcomes than proton pump inhibitors alone. Patients with concomitant obesity were recommended to undergo either gastric bypass or fundoplication, although patients with severe comorbid disease or BMI > 50 should undergo Roux-en-Y gastric bypass for the additional benefits that follow weight loss.

CONCLUSION

Using the recommendations an algorithm was developed by this panel, so that physicians may better counsel their patients with GERD. There are certain patient factors that have been excluded from included studies/trials, and so these recommendations should not replace surgeon-patient decision making. Engaging in the identified research areas may improve future care for GERD patients.

Surgical treatment of GERD: systematic review and meta-analysis

BACKGROUND

Gastroesophageal reflux disease (GERD) has a high worldwide prevalence in adults and children. There is uncertainty regarding medical versus surgical therapy and different surgical techniques. This review assessed outcomes of antireflux surgery versus medical management of GERD in adults and children, robotic versus laparoscopic fundoplication, complete versus partial fundoplication, and minimal versus maximal dissection in pediatric patients.

METHODS

PubMed, Embase, and Cochrane databases were searched (2004-2019) to identify randomized control and non-randomized comparative studies. Two independent reviewers screened for eligibility. Random effects meta-analysis was performed on comparative data. Study quality was assessed using the Cochrane Risk of Bias and Newcastle Ottawa Scale.

RESULTS

From 1473 records, 105 studies were included. Most had high or uncertain risk of bias. Analysis demonstrated that anti-reflux surgery was associated with superior short-term quality of life compared to PPI (Std mean difference =  - 0.51, 95%CI  - 0.63, - 0.40, I² = 0%) however short-term symptom control was not significantly superior (RR = 0.75, 95%CI 0.47, 1.21, I² = 82%). A proportion of patients undergoing operative treatment continue PPI treatment (28%). Robotic and laparoscopic fundoplication outcomes were similar. Compared to total fundoplication, partial fundoplication was associated with higher rates of prolonged PPI usage (RR = 2.06, 95%CI 1.08, 3.94, I² = 45%). There was no statistically significant difference for long-term symptom control (RR = 0.94, 95%CI 0.85, 1.04, I² = 53%) or long-term dysphagia (RR = 0.73, 95%CI 0.52, 1.02, I² = 0%). Ien, minimal dissection during fundoplication was associated with lower reoperation rates than maximal dissection (RR = 0.21, 95%CI 0.06, 0.67).

CONCLUSIONS

The available evidence regarding the optimal treatment of GERD often suffers from high risk of bias. Additional high-quality randomized control trials may further inform surgical decision making in the treatment of GERD.

Screening Esophagogastroduodenoscopy Before Laparoscopic Sleeve Gastrectomy: Results in 819 Patients

Aim: The routine use of esophagogastroduodenoscopy (EGD) during the preoperative evaluation of surgical weight loss candidates is controversial. The aim of this study is to evaluate the findings of preoperative EGD in patients who are scheduled for a primary laparoscopic sleeve gastrectomy (LSG). The probable effect of these findings on the medical and surgical strategy that was followed is assessed. Methods: Findings of EGD obtained from consecutive LSG candidates and all data were prospectively recorded and retrieved from the database. Results: A total of 819 patients underwent EGD successfully. Mean age and body mass index were 38 ± 11.3 and 43.17 ± 7.2 kg/m², respectively. Fifty-eight percent were female. EGD of 263 (32.1%) patients was normal and 687 (84%) patients were asymptomatic. At least one abnormal finding was detected in 65% of the asymptomatic patients. Abnormal findings that did not change the surgical strategy were found in 550 patients (67.2%). Findings such as gastritis or duodenitis that changed the medical management before surgery were found in 309 patients (38.2%). Helicobacter pylori was positive in 218 (26.6%) patients but eradication treatment was not applied in the preoperative period. No pathology was detected that would create absolute contraindication or change the type of surgery in any patient. Only technical modifications were required in 13% due to hiatal hernia. The timing of the planned surgery has changed in only 6 patients (0.74%) (early stage neuroendocrine tumor, leiomyoma, severe ulcer). Conclusions: Routine EGD performed before LSG did not change the planned bariatric option in any patient, but led to 13% rate of technical modifications due to the presence of hiatal hernia. At least one abnormal finding was detected in 65% of asymptomatic patients. Due to endoscopic findings, the rate of patients who started medical acid-suppression treatment in the preoperative period was 38%.

Cardiac Tamponade as a Life-Threatening Complication of Laparoscopic Antireflux Surgery: The Real Incidence and 3D Anatomy of a Heart Injury by Helical Tacks

Background: Cardiac tamponade (CT) is a dreadful complication of laparoscopic antireflux surgery (LARS) with unknown incidence, and preventive measures are yet to be defined. Incidence during LARS with respect to usage/configuration of graft deployment is analyzed. Three-dimensional (3D) analysis of tack distribution provided anatomical insight to prevent cardiac injury.

Materials and Methods: Data regarding the usage and configuration of graft deployment are retrieved from the prospective database. Grafting was “posterior” or “posterior + anterior.” Incidence of CT in all hiatoplasties is calculated. Tomography is reconstructed in 3D, showing the spatial distribution of the tacks. Tacks are numbered in the surgical video. Corresponding numbering is applied to the tacks in any particular tomography slice, utilizing the 3D images as an interface. A numbering-blinded radiologist is asked to identify the offending and the nonoffending tacks as the cause of tamponade. Tack-to-pericardium distances are recorded. Tacks having no measurable distance from the pericardium are regarded as offensive.

Results: One CT occurred in 1302 consecutive LARS (0.076%). The incidence is 0% when “no” (379) or “posterior” (880) graft is used as opposed to 2.3% rate in “posterior + anterior” (43) grafting. The distribution of “offensive,” “nonoffensive but nearest,” and “safe” tacks followed a pattern. All offensive tacks belonged to the anterior graft fixation, which we referred as the critical zone.

Conclusion: CT during LARS is rare, and associated with graft fixation anterior to the hiatal opening. Avoiding graft fixation to the critical zone may prevent cardiac injury.

Endoscopic stapling in comparison to laparoscopic fundoplication for the treatment of gastroesophageal reflux disease

BACKGROUND

The SRS(TM) Endoscopic Stapling System (Medigus Ltd, Omer, Israel) is a novel method for the treatment of gastroesophageal reflux disease (GERD). The present study assessed the safety and efficacy of SRS compared with laparoscopic anti-reflux surgery (LARS).

PATIENTS AND METHODS

Of 27 participants, 11 underwent SRS and 16 LARS. Symptoms were assessed using Velanovich GERD-health-related quality of life (GERD-HRQL) scores. The groups were compared in reference to operation time, improvement in GERD-HRQL scores, and postoperative course. Chi-squared and Mann-Whitney-U-tests were used for statistical analysis.

RESULTS

Of 16 (59.3%) male and 11 (40.7%) female patients, mean age was 39.6 (range: 24-60) years and mean body mass index was 26.2 kg/m(2) . Both groups were statistically similar. An esophageal perforation observed in the SRS group completely recovered after over-the-scope clipping. Procedure times for SRSand LARS were 89 and 47 min, respectively (P < 0.05). Mean discharge time was longer for SRS than LARS (3 days vs 1.2 days, P < 0.05). However, this difference disappeared with the exclusion of a complicated patient with long hospitalization in the SRS group. During 6 months mean follow up, proton-pump inhibitor use was insignificantly higher in the SRS group (P > 0.05). Mean GERD-HRQL scores dropped in 87% and in 64% of patients (P > 0.05) from 29.3 to 4.1 and from 24.8 to 8.9 (P = 0.016) in LARS and SRS groups, respectively.

CONCLUSION

The short-term results of SRS are promising. The forthcoming new-generation devices and increasing experience may further improve efficacy and decrease untoward effects.

Laparoscopic management of totally intra-thoracic stomach with chronic volvulus

AIM: To evaluate the outcomes of patients who underwent laparoscopic repair of intra-thoracic gastric volvulus (IGV) and to assess the preoperative work-up.

METHODS: A retrospective review of a prospectively collected database of patient medical records identified 14 patients who underwent a laparoscopic repair of IGV. The procedure included reduction of the stomach into the abdomen, total sac excision, reinforced hiatoplasty with mesh and construction of a partial fundoplication. All perioperative data, operative details and complications were recorded. All patients had at least 6 mo of follow-up.

RESULTS: There were 4 male and 10 female patients. The mean age and the mean body mass index were 66 years and 28.7 kg/m², respectively. All patients presented with epigastric discomfort and early satiety. There was no mortality, and none of the cases were converted to an open procedure. The mean operative time was 235 min, and the mean length of hospitalization was 2 d. There were no intraoperative complications. Four minor complications occurred in 3 patients including pleural effusion, subcutaneous emphysema, dysphagia and delayed gastric emptying. All minor complications resolved spontaneously without any intervention. During the mean follow-up of 29 mo, one patient had a radiological wrap herniation without volvulus. She remains symptom free with daily medication.

CONCLUSION: The laparoscopic management of IGV is a safe but technically demanding procedure. The best outcomes can be achieved in centers with extensive experience in minimally invasive esophageal surgery.

A clinical comparison of laparoscopic Nissen and Toupet fundoplication for gastroesophageal reflux disease

AIM

To compare the advantages and disadvantages of laparoscopic Nissen and Toupet fundoplication in the treatment of gastroesophageal reflux disease (GERD) and their indications.

PATIENTS AND METHODS

From June 2001 to December 2011, 383 patients with GERD were randomized into two groups according to the last number in their hospitalization number. Overall, 215 patients underwent laparoscopic Nissen fundoplication, and 168 underwent laparoscopic Toupet fundoplication.

RESULTS

No conversions to laparotomy or deaths were observed, and the symptoms disappeared completely postoperatively in both groups. Average follow-up was 5.6 years. No recurrence of symptoms was observed in the Nissen group. Eighteen patients experienced recurrence of symptoms in the Toupet group and were administered acid-suppressing drugs. Esophageal manometry and acid reflux testing were performed 4 months postoperatively, with normal results in both groups. The cure rate of esophageal inflammation was 88.4% in the Nissen group and 67.7% in the Toupet group. Four days postoperatively, the incidences of dysphagia and abdominal distension were significantly higher in the Nissen group compared with the Toupet group (28.4% and 16.7%, respectively); the difference between the two groups significantly decreased 1 year postoperatively (1.5% and 0.8%, respectively).

CONCLUSIONS

In the short term, the incidence of dysphagia was significantly lower after Toupet fundoplication, but the difference decreased significantly with extension of the postoperative recovery period. For patients with moderate to severe GERD, the laparoscopic Nissen fundoplication may be optimal; for elderly patients or for patients with significantly reduced esophageal peristalsis detected in preoperative examinations, the laparoscopic Toupet fundoplication should be considered.

Five-year efficacy of laparoscopic Nissen fundoplication versus anterior 180° partial fundoplication in the management of reflux esophagitis: A randomized controlled trial

AIM: To evaluate the long-term clinical outcome of laparoscopic Nissen fundoplication versus anterior 180° partial fundoplication in the management of reflux esophagitis.

METHODS: One hundred and seven patients with reflux esophagitis were enrolled and randomly allocated into two groups to undergo laparoscopic Nissen fundoplication (Nissen group) and laparoscopic anterior 180° partial fundoplication (partial fundoplication group). The patients were followed for 5 years after operation, and clinical data, such as the incidences of heartburn, dysphagia, bloating or flatulence, belching ability, and degree of satisfaction with the operation, were collected.

RESULTS: There were no statistical significances between the two groups for the incidence of heartburn symptom and consumption of PPI. Though the incidence of dysphagia was similar between the two groups, the severity of the symptom in the partial fundoplication group was much lower than that in the Nissen group. There is a higher incidence of epigastric bloating, difficulty of belching and flatulence in the Nissen group. The degree of overall satisfaction with the operation was similar between the two groups. Most patients were free of reflux symptoms during the 5-year follow-up period.

CONCLUSION: Laparoscopic anterior 180° partial fundoplication has good and durable anti-reflux effect and is associated with a lower incidence of post-operative complications compared to Nissen fundoplication, and can be employed as a routine procedure for treatment of gastroesophageal reflux disease.
