Prospective, randomized trial of bipolar electrosurgery vs ultrasonic coagulation for division of short gastric vessels during laparoscopic Nissen fundoplication

BACKGROUND: Division of the short gastric vessels (SGV) during laparoscopic Nissen fundoplication (LNF) may improve outcome. Several techniques are available for SGV division. The aim of this study was to compare in a prospective randomized trial bipolar electrocautery with cutting blade versus ultrasonic coagulation of the SGV during LNF. METHODS: In all, 86 consecutive patients undergoing LNF were prospectively randomized into two similar groups that underwent division of the SGV, respectively, using bipolar cutting forceps (BPCF) or harmonic coagulating shears (HCS). Operative time, bleeding episodes, complications, equipment problems, and surgeon's subjective scoring of satisfaction and ease of use were assessed. RESULTS: Mean (+/-SD) time for fundic mobilization and division of the SGV was not significantly different between the two groups (BPCF = 20 +/- 12 min vs. HCS = 22 +/- 12 min). Bleeding events, estimated blood loss, surgeon satisfaction, and subjective ease of use were similar, and no transfusions were required. Complications in the BPCF group included a delayed gastric perforation requiring reoperation and two gastric serosal burns repaired intraoperatively. There was one splenic capsular tear using the HCS and one splenic capsular tear using the BPCF, both of which were controlled intraoperatively. The number of functional equipment problems were few and statistically similar. In the authors' institution, the per case total costs with capital expenditures amortized over 100 cases indicate savings of approximately $202/case with use of the BPCF versus the HCS. Regression analysis demonstrated a significant correlation between body mass index (BMI) and total case length and time for division of the SGVs. CONCLUSIONS: The BPCF and HCS appear to be equally efficacious for SGV division during LNF. Judicious application of both energy forms and heightened vigilance for gastric serosal injury are required with use of both the BPCF and HCS in cases of tight gastrosplenic adhesions or short SGVs. The BPCF carries a potential cost advantage over the HCS in the authors' institution. The BMI directly correlates with time required to divide SGVs and total length of LNF.     

Prospective randomized double-blind trial between laparoscopic Nissen fundoplication and anterior partial fundoplication

BACKGROUND: In the operative management of gastro-oesophageal reflux, a balance must be achieved between adequate control of reflux and excessive dysphagia. The ideal technique is not known. A randomized study was performed to determine whether laparoscopic anterior fundoplication is associated with a lower incidence of postoperative dysphagia than laparoscopic Nissen fundoplication, while achieving equivalent control of reflux. METHODS: Patients presenting for laparoscopic antireflux surgery were randomized to undergo either a Nissen fundoplication (n = 53) or an anterior 180 degrees hemifundoplication (n = 54). Patients were blinded to which procedure had been performed, and follow-up was obtained by a blinded independent investigator. Standardized clinical grading systems were used to assess dysphagia, heartburn and patient satisfaction 1, 3 and 6 months after operation. Objective measurement of lower oesophageal sphincter pressure, oesophageal emptying time, distal oesophageal acid exposure and endoscopic healing of oesophagitis was also performed. RESULTS: Operating time was similar for the two procedures (58 min for the Nissen procedure versus 60 min for anterior fundoplication). Resting and residual lower oesophageal sphincter pressures were lower following anterior fundoplication (29 versus 18 mmHg, and 13 versus 6 mmHg), and oesophageal emptying times were faster (92 versus 116 s). Acid exposure times and ability to heal oesophagitis were similar. At 3 months' follow-up clinical outcomes were similar for the two procedures. At 6 months, however, patients who had undergone anterior fundoplication experienced significantly less dysphagia for solid food and were more likely to be satisfied with the clinical outcome. CONCLUSION: Laparoscopic anterior fundoplication achieved equivalent control of reflux, more physiological postoperative manometry parameters, and an improved clinical outcome at 6 months. Continued follow-up remains necessary to confirm the long-term efficacy of the partial fundoplication procedure.     

Laparoscopic Nissen fundoplication without division of short gastric vessels in children

Purpose

It has been suggested that routine division of short gastric vessels (SGVs) results in a more “floppy” Nissen fundoplication leading to improved outcomes, that is, less dysphagia and lower incidences of recurrent gastroesophageal reflux disease (GERD). The aim of this retrospective study was to assess whether laparoscopic Nissen fundoplication without division of SGVs (Rossetti modification) (laparoscopic Nissen-Rossetti fundoplication [LNRF]) is associated with acceptable clinical outcome in children.

Method

The charts of 368 children who underwent LNRF between January 1996 and September 2004 by 1 primary surgeon were retrospectively reviewed. Children were divided into 2 groups: LNRF + gastrostomy (A) and LNRF alone (B). Mean follow-up period of all groups was 4.2 years.

Results

Laparoscopic Nissen-Rossetti fundoplication was completed in 99% (365/368). Mean operating time for group A was 74 minutes and 61 minutes for group B. None in group A required postoperative esophageal dilatation, and 9 in group B (22.5%) required 12 dilatations; 3.6% developed recurrent GERD, 3.7% in group A and 2.5% in group B.

Conclusion

Laparoscopic Nissen-Rossetti fundoplication can be performed with acceptable long-term outcome in children, especially in the majority also requiring chronic gastrostomy access. Short-term, reversible dysphagia may be seen in a small percentage of children having fundoplication alone.     

New technology for the division of short gastric vessels during laparoscopic Nissen fundoplication

Division of the short gastric vessels (SGV) is a standard component of laparoscopic Nissen fundoplications (LNF) at our institution. This study compares our original method of vessel control, multifire clip applier (MCA) and sharp division, to the Ultracision Harmonic Scalpel LCS (LCS). Twenty consecutive patients were evaluated in a randomized prospective fashion. Times for SGV division and estimated blood loss (EBL) were recorded. Cost data represent patient charges for use of either the MCA or LCS and the charge for operative time. Use of the LCS produced a significant reduction in the time required for SGV division and in the charges to the patient.

Prospective randomized trial comparing Nissen to Nissen-Rossetti technique for laparoscopic fundoplication

BACKGROUND: It has been suggested that division of the short gastric vessels (SGV) provides a more floppy Nissen fundoplication, for the treatment of reflux disease. The aim of the study was to assess whether Nissen fundoplication with division of SGV is associated with improved clinical outcome and laboratory findings. METHODS:Fifty-six consecutive patients with gastroesophageal reflux disease (GERD) were randomly assigned to have a laparoscopic Nissen fundoplication either with division (24 patients; 15 men; mean age 51 +/- 15 years) or without division (32 patients; 23 men, mean age 47 +/- 14 years) of the SGV. Preoperative and postoperative investigation included clinical assessment, esophagoscopy, esophagogram, esophageal manometry, and 24-hour ambulatory esophageal pH monitoring. RESULTS: Division of the SGV resulted in a significant increase of the operating time (P <0.0001). The operation abolished reflux in both groups. Also, both types of Nissen fundoplication significantly increased the amplitude of peristalsis at distal esophagus (division group: from 56 +/- 20 mm Hg to 64 +/- 25 mm Hg, P = 0.01; nondivision group: from 65 +/- 27 mm Hg to 75 +/- 26 mm Hg, P <0.001) and the lower esophageal sphincter pressure (division group: from 16 +/- 10 mm Hg to 24 +/- 7 mm Hg, P <0.001; nondivision group: from 22 +/- 8 mm Hg to 28 +/- 5 mm Hg, P <0.001). No differences in the incidence of postoperative severe dysphagia (division group: 5 of 24; nondivision group: 3 of 32) and overall esophageal transit were accounted between groups. However, division of the SGV was associated with a significant increased incidence of gas-bloating syndrome (division group, 13 of 24, versus nondivision group, 9 of 32, P = 0.02). CONCLUSIONS: Division of the SGV at laparoscopic Nissen fundoplication for GERD does not improve clinical outcome and laboratory findings, while it is associated with prolongation of the operating time and increased incidence of gas-bloating syndrome.

Randomized double-blind trial of laparoscopic Nissen fundoplication versus anterior partial fundoplication

BACKGROUND: This double-blind, randomized study compared outcomes of laparoscopic Nissen total fundoplication and anterior partial fundoplication carried out by a single surgeon in a private practice. METHODS: All patients with proven gastro-oesophageal reflux disease, regardless of motility, presenting for laparoscopic antireflux surgery were randomized to either Nissen total or anterior partial fundoplication. Primary outcome measures were dysphagia and abolition of reflux. Secondary outcome measures were Visick scores, bloating, patient satisfaction and reoperation rate. RESULTS: Complete follow-up was available for 161 (98.8 per cent) of 163 patients (84 Nissen, 79 anterior). There were no differences in mean heartburn scores between groups. Recurrent reflux was observed in ten patients after anterior fundoplication, but none after the Nissen procedure. Dysphagia scores for both liquids and solids were lower after anterior fundoplication. Four patients had persistent troublesome dysphagia after Nissen fundoplication compared with none after anterior fundoplication. There were no differences between groups in postoperative bloating. The overall reoperation rate at 2 years was 7 per cent, all achieved laparoscopically. CONCLUSION: Nissen fundoplication cured reflux in all patients up to 2 years, but 5 per cent required revisional surgery. Recurrent reflux was more common after anterior fundoplication, but dysphagia was rare. Patient satisfaction was excellent in both groups. Revisional laparoscopic surgery was safe and usually successful.     

Splenic abscess after laparoscopic Nissen fundoplication: a consequence of short gastric vessel division

A 53-year-old male patient underwent a Nissen fundoplication with short gastric vessel (SGV) division for gastroesophageal reflux disease. During the procedure, the upper pole of the spleen was noted to have discrete color changes suggesting ischemia of this area. One month later he presented with a splenic abscess, which required splenectomy. The clinical presentation and management of this case is reported and comments are made on surgical aspects of SGV division during fundoplication to prevent this potentially dangerous situation. Issues such as the surgical management of splenic abscesses, the limitations of laparoscopic splenectomy in these cases, and the risks and benefits of SGV division, are also discussed in this article.     

Division of the short gastric vessels during laparoscopic Nissen fundoplication: clinical and functional outcome during long-term follow-up in a prospectively randomized trial

Background

Although the first laparoscopic Nissen fundoplication was performed almost two decades ago, division of the short gastric vessels is still controversially discussed. The aim of this prospectively randomized trial was to evaluate the clinical and functional outcome following laparoscopic Nissen fundoplication with division versus saving of the short gastric vessels during short- and long-term follow-up.

Methods

Forty-one consecutive patients (30 men, 11 women) with gastroesophageal reflux disease were allocated to undergo Nissen fundoplication without division (group 1, n = 19) or with division (group 2, n = 22) of short gastric vessels. All patients were evaluated prior to and at 6 months as well as 5 years following fundoplication. Tests included endoscopy, barium swallow, 24-h pH monitoring, and esophageal manometry. Gastroesophageal reflux disease (GERD) symptoms were evaluated and a gastrointestinal quality-of-life index was calculated.

Results

Preoperative symptoms such as heartburn (84/86%), regurgitation (79/86%), pulmonary symptoms (47/45%), dysphagia (11/32%), chest pain (16/9%), and globus sensation (21/27%) were seen in groups 1 and 2, respectively. In group 1 regurgitation and mild dysphagia were seen in 7 and 26% of patients, respectively, at 5 years. In group 2 the rate of dysphagia decreased from 32 to 17% during short-term follow-up, but increased thereafter to 18%. Reflux esophagitis (preoperative rates: group 1, 74%; group 2, 59%) disappeared in all patients after fundoplication. Mean operative time (group 1, 109 min versus group 2, 125 min; p < 0.05) and mean blood loss (group 1, not measurable; group 2, 25 ml; p < 0.05) showed statistically significant differences. DeMeester score improved in group 1 from 26.6 to 2.2 and in group 2 from 24.7 to 2.5 at 5-year follow-up (p = 0.02). Lower esophageal sphincter (LES) resting pressure returned to normal values (group 1, 23.9 mmHg; group 2, 24.6 mmHg; p < 0.007) with regular relaxation. Quality-of-life index was high in both cohorts, without statistically significant differences between the two groups.

Conclusion

Routine division of the short gastric vessels during Nissen fundoplication in the followed patient group yields neither functional nor clinical advantages in short- or long-term follow-up.     

A prospective randomized trial of laparoscopic Nissen fundoplication with anterior vs posterior hiatal repair.

HYPOTHESIS: The technique used for repair of the esophageal hiatus during laparoscopic Nissen fundoplication can influence the likelihood of postoperative dysphagia. DESIGN: A prospective double-blind randomized control trial. SETTING: A university teaching hospital. PARTICIPANTS: A total of 102 patients with proven gastroesophageal reflux disease, undergoing a laparoscopic Nissen fundoplication were randomized to undergo fundoplication with either anterior (47 patients) or posterior (55 patients) repair of the diaphragmatic hiatus. Patients were excluded for the following reasons: they had esophageal motility disorders, required a concurrent abdominal procedure, had undergone previous antireflux surgery, or had very large hiatus hernias. INTERVENTIONS: Laparoscopic Nissen fundoplication with anterior vs posterior hiatal repair. MAIN OUTCOME MEASURES: Independent assessment of dysphagia, heartburn, patient satisfaction, and other symptoms 1, 3, and 6 months following surgery, using multiple standardized clinical grading systems. Objective measurement of lower esophageal sphincter pressure, esophageal emptying time, distal esophageal acid exposure, and endoscopic assessment of postoperative anatomy and esophageal mucosa. RESULTS: Symptoms of postoperative dysphagia, relief of heartburn, and overall satisfaction 6 months after surgery were not influenced by the hiatal repair technique. However, to achieve a similar incidence of dysphagia, more patients who initially underwent posterior hiatal repair required a second surgical procedure (6 vs 0 patients). The hiatal repair technique did not affect the likelihood of early postoperative paraesophageal herniation. CONCLUSION: Anterior suturing of the hiatus appears to be at least as good in the short-term as posterior suturing as a method of narrowing the hiatus during laparoscopic Nissen fundoplication.
