Does laparoscopic Nissen fundoplication lead to chronic gastrointestinal dysfunction?

BACKGROUND: Laparoscopic Nissen fundoplication (LNF) efficiently controls the symptoms of gastroesophageal reflux disease (GERD); however, other nonspecific gastrointestinal (GI) symptoms have been reported following LNF. The aim of this study was to evaluate the long-term effects of LNF on nonspecific GI complaints. METHODS: The basis for this study is the prospective follow-up of 515 patients (mean age 46 +/- 13 years) who underwent a LNF between 1992 and 1998. A questionnaire was designed to evaluate GERD symptoms (i.e., heartburn, epigastric pain, regurgitation, dysphagia, and fullness, score 0-60) and nonspecific GI symptoms (i.e., vomiting, diarrhea, constipation, and lack of appetite, score 0-48). Patients were assessed before surgery, at 6 months, 2 years, and 5 years after surgery. RESULTS: Laparoscopic Nissen fundoplication was associated with a significant decrease in both GERD and nonspecific GI symptoms score at 6 months and up to 5 years, in the whole group (p < 0.001). 360 patients (69.7%) had preoperative nonspecific GI symptoms and experienced a significant reduction in these symptoms following the surgery and lasting up to 5 years. The other 155 patients (30.3%) had no preoperative GI symptoms (GI symptoms score of 0). In this group, there was a small but statistically significant increase in GI symptoms score (p < 0.001). It was, however, clinically significant (defined as a score >12) in only 9.9% of the patients. CONCLUSIONS: Laparoscopic Nissen fundoplication provides an efficient treatment of GERD up to 5 years, and in a majority of patients, it is not associated with any significant increase in nonspecific GI complaints. New nonspecific bowel symptoms can develop after LNF in some patients but are unlikely to be clinically significant.

The role of telementoring and telerobotic assistance in the provision of laparoscopic colorectal surgery in rural areas.

PURPOSE: The aim of this study was to assess whether telementoring and telerobotic assistance would improve the range and quality of laparoscopic colorectal surgery being performed by community surgeons. METHODS: We present a series of 18 patients who underwent telementored or telerobotically assisted laparoscopic colorectal surgery in two community hospitals between December 2002 and December 2003. Four community surgeons with no formal advanced laparoscopic fellowship were remotely mentored and assisted by an expert surgeon from a tertiary care center. Telementoring was achieved with real-time two-way audio-video communications over bandwidths of 384 kbps-1.2 mbps and included one redo ileocolic resection, two right hemicolectomies, two sigmoid resections, three low anterior resections, one subtotal colectomy, one reversal of a Hartmann operation, and one abdominoperineal resection. A Zeus TS microjoint system (Computer Motion Inc, Santa Barbara CA) was used to provide telepresence for the telerobotically assisted laparoscopic procedures, which included three right hemicolectomies, three sigmoid resections, and one low anterior resection. RESULTS: There were no major intraoperative complications. There were two minor intraoperative complications involving serosal tears of the colon from the robotic graspers. In the telementored cases, there were two postoperative complications requiring reoperation (intra-abdominal bleeding and small bowel obstruction). Two telementored procedures were converted because of the mentee's inability to find the appropriate planes of dissection. One telerobotically assisted procedure was completed laparoscopically by the local surgeon with aid of telementoring because of inadequate robotic arm position. The median length of hospital stay for this series was 4 days. The surgeons considered telementoring useful in all cases (median score 4 out of 5). The use of remote telerobotic assistance was also considered a significant enabling tool. CONCLUSIONS: Telementoring and remote telerobotic assistance are excellent tools for supporting community surgeons and providing patients better access to advanced surgical care.

Effects of laparoscopic Nissen fundoplication on esophageal motility: long-term results.

BACKGROUND: This study aimed to evaluate the long-term impact of laparoscopic Nissen fundoplication on esophageal motility in patients with preoperative esophageal dysmotility. METHODS: This study prospectively followed 580 patients who underwent laparoscopic Nissen fundoplication between 1992 and 1999. Esophageal manometry, 24-h pH monitoring, and symptom score assessment were performed before surgery, then 6 months, 2 years, and 5 years after surgery. Preoperatively, 533 of the patients (93.5%) had normal esophageal contractile pressure (group 1), whereas 38 of the patients (6.5%) had reduced contractile pressure (<30 mmHg) (group 2). RESULTS: Esophageal contractile pressures increased significantly in the patients with low preoperative values, whereas it remained unchanged in the patients with normal preoperative contractile pressures. Both groups reported a significant reduction in the dysphagia symptom score after surgery. CONCLUSION: Nissen fundoplication produces a significant long-lasting increase in esophageal contractile pressures in patients with preoperative esophageal dysmotility (i.e., contractile pressure lower than 30 mmHg). Preoperative esophageal dysmotility is therefore not a contraindication to laparoscopic Nissen fundoplication.

Effect of pregnancy on effectiveness of laparoscopic Nissen fundoplication.

BACKGROUND: Symptoms of gastroesophageal reflux disease (GERD) are experienced by up to 85% of pregnant women. Some young women on maintenance proton pump inhibitor (PPI) treatment are choosing surgery to stop their medical treatment and avoid severe symptoms during pregnancy. There are no reports describing the effect of pregnancy on the long-term efficacy of laparoscopic Nissen fundoplication. The aim of this study was to evaluate the effect of pregnancy on the efficacy of laparoscopic Nissen fundoplication. METHODS: This study surveyed 146 women of childbearing age with proven GERD who had undergone laparoscopic Nissen fundoplication from 1992 through 2002. The patients who became pregnant (group 1) were compared with those who did not (group 2). RESULTS: The study focused on 25 patients who became pregnant after surgery. Of these patients, 40% (n = 10) had chosen surgery as a way to discontinue PPI treatment before pregnancy. The mean time from laparoscopic Nissen fundoplication to pregnancy was 25.9 +/- 4.6 months. A total of 19 patients (76%) had no reflux symptoms, whereas 5 (20%) required antacids during pregnancy. One patient (4%) experienced an acute intrathoracic stomach migration during her pregnancy and required emergency open surgery, which resulted in the loss of her fetus. After pregnancy, six patients (24%) had recurrence of GERD symptoms, and three (12%) required a redo fundoplication. The higher rate of GERD recurrence (24% vs 16.7%) and redo surgery (12% vs 4%) in group 1 did not reach statistical significance, but showed a definite trend. CONCLUSION: For most patients, laparoscopic Nissen fundoplication is effective in controlling GERD symptoms during and after pregnancy.

Intramuscular interstitial cells of Cajal associated with mast cells survive nitrergic nerves in achalasia.

Achalasia is dominated by injury to inhibitory nerves. As intramuscular interstitial cells of Cajal (ICC-IM) are proposed to form functional units with nitrergic nerves, their fate in achalasia may be critically important. We studied the relationship between loss of nitrergic nerves and injury to ICC-IM in patients with achalasia and determined associations between ICC-IM and mast cells (MC), using quantitative immunohistochemistry and electron microscopy. Loss of neuronal nitric oxide synthase (nNOS) immunoreactivity was completed within 3 years of acquiring achalasia. Thereafter, progressive ultrastructural injury to remaining nerve structures was evident. Within the first 2 years, the number of ICC-IM did not decline although ultrastructural injury was already present. Thereafter, loss of ICC-IM occurred unrelated to duration of disease. Damage to ICC-IM appeared unrelated to nerve injury. A significant MC infiltration was observed in the musculature; the number of MC was positively related to the persistent number of ICC-IM. Mast cell formed close contacts with ICC-IM and piecemeal-degranulation occurred towards ICC-IM. In conclusion, injury to ICC-IM in achalasia is variable, but not related to duration of disease and injury to nitrergic nerves. MC are prominent and form close functional contact with ICC-IM which may be responsible for their relatively long survival.

Long-term outcomes of laparoscopic surgery for colorectal cancer.

Multiple reports have outlined the potential benefits of the laparoscopic approach to colon surgery. Recently, randomized control trials have demonstrated the safety of applying these techniques to colorectal cancer. This study examined the long-term follow-up assessment of patients after laparoscopic colorectal cancer resections and compared them with a large prospective database of open resections. A total of 231 resections were performed for adenocarcinoma of the colon or rectum between 1992 and 2004. Of these 231 resections, 93 were rectal (40.3%) and 138 were colonic (59.7%). A total of 8 (3.2%) of the resections were performed as emergencies, and 27 (11.7%) were converted to open surgery. The mean follow-up period was 35.84 months (range, 0-132 months). The disease recurred in 51 of the patients (22.1%) before death, involving 14 (6.1%) local and 37 (16%) distant recurrences. Only two patients had wound recurrences (0.8%), and both patients had widespread peritoneal recurrence at the time of diagnosis. The overall survival rate was 65.3% at 60 months and 60.3% at 120 months. The disease-free survival rate was 58% at 60 months and 56% at 120 months. Laparoscopic techniques can be applied to a wide range of colorectal malignancies without sacrificing oncologic results during a long-term follow-up period.

Outcome of laparoscopic Nissen fundoplication in patients with body mass index >or=35.

BACKGROUND: To date, few studies have examined the effect of morbid obesity on the outcome of laparoscopic antireflux surgery and results have been conflicting. The aim of this work was to study the outcome of laparoscopic Nissen fundoplication (LNF) in patients with body mass index (BMI) >or= 35. METHODS: We prospectively followed 70 patients (15 men, 55 women) with a proven diagnosis of gastroesophageal reflux disease (GERD) and a mean BMI of 38.4 +/- 0.5 (range, 35-51) who underwent LNF. All patients underwent 24-h pH study, esophageal manometry, upper gastrointestinal (GI) endoscopy, and GERD symptom score before and 6 months after LNF. Surgical outcomes were compared to those of 70 sequential nonobese patients (BMI < 30) who also underwent LNF. RESULTS: LNF was completed laparoscopically in 69 of 70 patients in the morbidly obese (MO) group and in all 70 patients in the normal-weight (NW) group. The mean operative time for the MO group was not significantly longer than that for the NW group (55.9 +/- 2.3 min vs 50.0 +/- 2.1 min), but the mean length of stay was significantly longer (3.17 +/- 0.2 days vs 2.2 +/- 0.1 days, p < 0.0001) in the MO group. There was one postoperative complication (a transhiatal herniation of the stomach) in the morbidly obese group. In both patient groups, LNF resulted in a significant increase in lower esophageal sphincter (LES) pressures. This was associated with a significant decrease in percent acid reflux in 24-h testing and a significant improvement in GERD symptom score in both groups, although patients in the MO group had a significantly higher mean reflux symptom score after surgery than did those in the NW group. After a mean follow-up of 41.6 +/- 2.9 months, one patient in the MO group required reoperation and one proton pump inhibitor therapy (PRN PPI), as required. CONCLUSIONS: Morbid obesity does not adversely affect the outcome of LNF. The conversion rate is low when performed by an experienced surgeon.

Long-term outcomes of laparoscopic heller cardiomyotomy without an anti-reflux procedure.

Certain technical features of laparoscopic Heller cardiomyotomy (LHM) remain controversial, including the extent of the myotomy and the indication for an antireflux procedure. We completed a retrospective chart review of all patients who underwent LHM for achalasia at 1 tertiary care institution to review our institutional experience with LHM without an antireflux procedure. Forty patients underwent a LHM performed by 2 surgeons, 65% of whom had previous medical management (Botox: 12 patients, LES dilatation: 14). The operating time was significantly increased in patients with Botox injections (98.3 vs. 71.1 minutes, P = 0.005). There were 3 intraoperative complications (mucosal injury in 3 patients, 2 had Botox injections). Postoperative evaluation demonstrated a mean dysphagia score of 0.2, a mean heartburn score of 3.2, and a mean LES pressure of 6.32 mm Hg. Thirty-two patients are maintained on acid-suppressing medications with good control of reflux symptoms. LHM without an antireflux procedure achieves excellent clinical outcomes in most patients with achalasia regardless of previous medical management. Previous medical management may present a greater technical challenge and may place patients at increased risk of mucosal injury.

Does laparoscopic fundoplication provide long-term control of gastroesophageal reflux related cough?

BACKGROUND: Of patients with chronic cough, 21% have GERD. Up to half of these patients may not respond adequately to medical, but the long-term results of antireflux surgery for cough is unknown. METHODS: A total of 905 patients (209 with respiratory symptoms, mainly cough) underwent laparoscopic Nissen fundoplication. Preoperatively patients underwent esophageal motility studies, 24-h pH monitoring, and symptom evaluation using a validated scale. Of eligible patients, 81% were followed at 6 months, 73% at 2 years, and 60% at 5 years. RESULTS: Before surgery, 83% of respiratory patients (RP) and 51% of nonrespiratory patients (NRP) had cough. RP had higher cough scores ( p < 0.0001), but improvement in cough compared to baseline was similar in the RP and NRP ( p = 0.1105 at 6 months, 0.4206 at 2 years, and 0.1348 at 5 years). Cough improved in 83% at 6 months, 74% at 2 years, and 71% at 5 years. CONCLUSIONS: Laparoscopic Nissen fundoplication is successful in the long-term control of GERD-related cough, even in patients who fail medical therapy.

Outcome of laparoscopic redo fundoplication.

BACKGROUND: To date, there has been no objective evidence for the effectiveness of laparoscopic redo fundoplication. We therefore reviewed our experience and based our analysis on a number of objective parameters. METHODS: We prospectively followed 28 consecutive patients (five men and 23 women; mean age, 48.64 +/- 2.57 years) who required redo fundoplication. These patients were part of a series of laparoscopic Nissen fundoplications done between 1992 and 2001. The indications were recurrent symptoms of gastroesophageal reflux disease (GERD) (21 patients), acute herniation of the wrap (three patients), and chronic paraesophageal hernia (four patients). A diagnosis of recurrent GERD was based on endoscopy, 24-h pH study, manometry, and symptom score evaluation. A diagnosis of paraesophageal and acute herniation was based on contrast swallow studies and/or gastroscopy. RESULTS: Twenty-six redo fundoplications were completed laparoscopically; two were converted to open. The mean operative time was 55.43 +/- 3.81 min. There were no intraoperative complications. The mean hospital stay was 3.0 +/- 0.35 days. Postoperative complications included postoperative pneumonia in one patient. Two patients from the laparoscopic group required a third operation-one for acute herniation of the redo wrap, which was fixed laparoscopically, and the other for acute recurrent paraesophageal hernia, which was fixed via an open transthoracic approach. The mean follow-up after revision is 25.14 +/- 3.48 months, with a significant decrease in acid reflux from 5.01% +/- 0.99 to 0.48% +/- 0.23 ( p < 0.0001), a significant decrease in symptom score from 28.96 +/- 2.93 to 10.75 +/- 2.61 ( p < 0.0001), and a small but significant increase in lower esophageal sphincter (LES) pressure from 13.71 +/- 1.79 to 16.69 +/- 1.50 ( p = 0.04). CONCLUSIONS: Laparoscopic redo fundoplication is technically feasible and clinically effective over a 2-year objective follow-up. Conversion and complication rates are low.

Surgical outcome in gastro-esophageal reflux disease patients with inadequate response to proton pump inhibitors.

Laparoscopic fundoplication (LF) has been shown to be effective in treatment of patients with gastro-esophageal reflux disease (GERD) requiring long-term medical therapy. Its effectiveness in patients with poor response to proton pump inhibitors (PPIs) has been questioned. We prospectively followed 445 patients with proven GERD inadequately controlled on PPI (up to 120 mg/day) and 274 GERD patients with good response to PPIs (20-120 mg/day) after LF. Patients in both groups underwent 24 h pH testing, esophageal manometry, symptom score evaluation, and quality-of-life (QOL) assessment (SF-36) before and at 6 months, 2 years, and 5 years after surgery. LF was associated with a marked improvement in percentage acid reflux, lower esophageal sphincter pressure, and symptom control in both groups of patients; however, the poor responders to PPIs also had a significant improvement in both physical and mental health component of the QOL assessment. Laparoscopic fundoplication provides an excellent symptom control for GERD patients, even those who have responded inadequately to large doses of PPIs. GERD patients who respond poorly to PPI therapy have significantly lowered physical and mental health QOL scores. Laparoscopic fundoplication in this group of patients leads to marked improvement of both components of QOL by 2 years after surgery.

Does laparoscopic antireflux surgery prevent the occurrence of transient lower esophageal sphincter relaxation?

BACKGROUND: Transient lower esophageal sphincter relaxation (TLESR) is the most common mechanism underlying gastroesophageal reflux disease (GERD), causing 70% to 100% of the reflux episodes in normal subjects and 63% to 74% of the reflux episodes in patients with reflux disease. This study aimed to evaluate the effect of laparoscopic Nissen fundoplication on TLESR in patients with proven GERD. METHODS: We prospectively followed 73 consecutive patients (13 men and 60 women; mean age, 43.7 +/- 1.72 years) with proven diagnosis of GERD and reported TLESRs found during a 40-min esophageal manometric study. These patients had repeat testing 6 months after undergoing laparoscopic Nissen fundoplication. RESULTS: Laparoscopic Nissen fundoplication increased the basal and nadir lower esophageal sphincter (LES) pressure and significantly reduced the number of TLESRs during the manometric study. No patients after surgery exhibited TLESR with nadir less than 2 mmHg. However, 8 of the 73 patients (11%) exhibited TLESR to a nadir exceeding 50% of basal pressure (mean nadir, 5.0 +/- 1.07 mmHg). CONCLUSIONS: The number of TLESRs is reduced significantly by antireflux surgery. Even accounting for increased basal and nadir pressures, the incidence of TLESR is reduced, suggesting that there may be additional mechanisms involved in this process.

Assessment of the afferent vagal nerve in patients with gastroesophageal reflux.

BACKGROUND: The objective of this study was to assess the integrity of the vagal nerve afferent pathways in patients with gastroesophageal reflux disease (GERD). METHODS: Seven GERD patients (4 males and 3 females, mean age 39 +/- 8 years) were studied. Twelve healthy volunteers (11 males and 1 female, mean age 32 +/- 8 years) were used as the control group. Cortical evoked potentials were measured. Electrical stimulation of the esophageal mucosa was performed through a custom-built device. Latencies and N2/P2 amplitude were measured. RESULTS: Reproducible cortical evoked potentials were obtained from all subjects. The stimulation threshold for GERD patients to electrical esophageal stimulation was 5.1 +/- 1.5 mA compared to 7.8 +/- 2.0 mA in healthy volunteers (p <0.05). There was no difference in peak latencies or N2/P2 amplitude between GERD patients and controls. CONCLUSIONS: GERD patients have a normal vagal nerve function, but they exhibit a decreased threshold for esophageal perception. The mechanism responsible for increased esophageal sensitivity observed in GERD patients is still undetermined and warrants further study.

Preoperative symptom evaluation and esophageal acid infusion predict response to laparoscopic Nissen fundoplication in gastroesophageal reflux patients who present with cough.

BACKGROUND: Most patients with cough and gastroesophageal reflux disease (GERD) improve on medical treatment with proton pump inhibitors (PPI). Nonresponders may be considered for antireflux surgery, but the selection of patients is difficult. METHODS: We have performed laparoscopic Nissen fundoplications (LNF) in 677 patients. Of these patients, 81% have undergone 6-month follow-up assessment with 24-h pH testing, esophageal manometry, symptom scores, and quality-of-life scores. RESULTS: LNF controlled heartburn in 93% and improved cough in 81%. Stepwise multiple regression showed that the preoperative cough score (r = 0.620, p <0.0001) and change in cough on and off PPI (r = 0.296, p = 0.0002) predicted improvement after surgery. A positive result on a randomized acid infusion test was associated with a greater improvement in cough after surgery (p = 0.0243). CONCLUSION: An acid infusion test and assessment of cough on and off PPI may be useful preoperative tools for the selection of patients with cough for LNF.

Local, exendin-(9-39)-insensitive, site of action of GLP-1 in canine ileum.

Glucagon-like peptide-1 (GLP-1) modulates glucose levels following a meal, including by inhibition of gastric emptying and intestinal transport. Intra-arterial injection of GLP-1 into the gastric corpus, antrum, or pylorus of anesthetized dogs had no effect on the contractile activity of the resting or neurally activated stomach. GLP-1 injected intra-arterially inhibited intestinal segments when activated by enteric nerve stimulation but not by acetylcholine. Isolated ileum segments were perfused intra-arterially, instrumented with strain gauges to record circular muscle activity and with subserosal electrodes to stimulate enteric nerves. GLP-1 caused concentration-dependent inhibition of nerve-stimulated phasic but not tonic activity. This was absent during TTX-induced activity and partly prevented by N(G)-nitro-L-arginine. Exendin-(9-39), the GLP-1 antagonist, had no intrinsic activity and did not affect the actions of GLP-1. Capsaicin mimicked the effects of GLP-1 and may have reduced the effect of subsequent GLP-1. GLP-1 may mediate paracrine action on afferent nerves in the canine ileal mucosa using an unusual receptor.

Laparoscopic vs. open resection for colorectal adenocarcinoma.

PURPOSE: To compare the outcome after laparoscopic versus open resection for colorectal adenocarcinoma. METHODS: A retrospective cohort analysis of all patients undergoing elective resection for colorectal adenocarcinoma between November 1992 and June 1999 at a university-affiliated hospital. These included 219 open (mean age, 68.3 years) and 98 laparoscopic (mean age, 70.3 years) resections. Data from converted cases (n = 12) were included in the laparoscopic group using the intention-to-treat principle. RESULTS: Operative time, lymph node yield, resection margins and postoperative morbidity and mortality were similar between laparoscopic and open technique. Parenteral analgesic use was less in the laparoscopic group (laparoscopic, 2.7; open, 3.2 days; P = 0.021). Time to first flatus (laparoscopic, 1.8; open, 3 days; P < 0.0001) and first bowel movement (laparoscopic, 3.5; open, 4.9 days; P < 0.0001) was shorter in the laparoscopic group. Resumption of an oral liquid diet (laparoscopic, 2.1; open, 4 days; P < 0.0001) and solid diet (laparoscopic, 5.2; open, 7.1 days; P < 0.0001) was also quicker in the laparoscopic patients. Length of hospitalization was significantly shorter in the laparoscopic patients (laparoscopic, 6.9; open, 10.9 days; P < 0.001). There were less minor complications in the laparoscopic group (laparoscopic, 11.2; open, 21.5 percent; P = 0.029) but no difference in major complications or perioperative mortality. Recurrence, disease-free and overall survival were similar between the two groups. No port site recurrences occurred in the laparoscopic group but there were three wound recurrences in the open group. CONCLUSIONS: Laparoscopic resection for colorectal cancer can be performed safely and effectively in tertiary centers. Earlier discharge from hospital, quicker resumption of oral feeds and less postoperative pain are clear advantages. No adverse effect on recurrence or survival was noted, but results of prospective, randomized trials, currently underway, are needed before laparoscopic resection for colorectal cancer becomes the standard of practice.

Laparoscopic versus open bowel resection for Crohn's disease.

BACKGROUND: Laparoscopic bowel resection is an alternative to open surgery for patients with Crohn's disease requiring surgical resection. The present report describes a seven-year experience with the laparoscopic treatment of Crohn's disease compared with the open technique in a tertiary Canadian centre. PATIENTS AND METHODS: A retrospective analysis of 61 consecutive patients undergoing elective resection for Crohn's disease was carried out between October 1992 and June 1999. This analysis included 32 laparoscopic resections (mean age 33 years) and 29 open resections (mean age 42 years). Patient demographics were compared, as well as short and long term outcomes after surgery (mean follow-up 39 months). RESULTS: Patients in the laparoscopic group were younger and had fewer previous bowel surgeries than patients who had open resections. Indications for surgery and operative times were similar between the groups. Patients who underwent laparoscopic resections required fewer doses of narcotic analgesics. The resumption of bowel function after surgery, and tolerance of a clear liquid and solid diet was quicker in the laparoscopic group. Patients who underwent laparoscopic resections had significantly shorter hospital stays than those who underwent open resections. Fifteen patients (48.4%) in the laparoscopic group experienced recurrence of disease compared with 13 patients (44.8%) in the open group. In both groups, the most common site of recurrence was at the anastomosis. The disease-free interval was the same length for both groups (23.9+/-17.3 months for the laparoscopic resection patients compared with 23.9+/-20.2 months for the open resection patients; P=1.00). CONCLUSIONS: Laparoscopic resection for Crohn's disease can be performed safely and effectively. Quicker resumption of oral feeds, less postoperative pain and earlier discharge from hospital are advantages of the laparoscopic method. No differences in the recurrence rate or the disease-free interval were noted.
