Single-incision and dual-incision laparoscopic adjustable gastric band: evaluation of initial experience.

BACKGROUND: The laparoscopic adjustable gastric band (LAGB) technique has been well described. Most surgeons have used a 4-trocar technique, with an additional incision for a liver retractor. Single incision (SI)-LAGB seeks to further decrease the invasiveness of the procedure. The purpose of the present report was to evaluate the safety and feasibility of SI-LAGB and the effect on the learning curve. METHODS: All cases performed from October 2008 to October 2009 were reviewed. Both true SI and dual-incision LAGB cases were included. The cases were performed through either a left paramedian or a transumbilical incision. The liver was retracted using the Nathanson retractor or an intracorporeal retractor. RESULTS: Of the 89 patients studied, 89% were women. Their mean age was 41 ± 12 years (range 19-74), and their body mass index was 46 ± 12 kg/m(2) (range 32-63). The first 27 patients underwent dual-incision LAGB using the Nathanson retractor. The operative time was 45 ± 12 minutes (range 21-90). After the first 35 cases, a reduction in the operative time was observed (P = .03). Simultaneous hiatal hernia repair added an average of 11 minutes of operative time for 40 patients (45%). The conversion rate was 26% for the first 35 cases, 5% for the second 35 cases, and 0% for the last 19 cases. Conversion was represented by adding a 5-mm trocar or the Nathanson retractor. The length of stay was 7 ± 9 hours (range 2-36), and 81 patients (91%) qualified for outpatient surgery. The complications included 1 seroma, 1 reoperation because of band obstruction, and 1 case of esophageal dysmotility after surgery. CONCLUSION: The results of our study have shown that SI-LAGB is a viable alternative to traditional LAGB and can be considered reliable, with low morbidity. The learning curve for consistent completion of SI-LAGB in our experience appeared to be the first 35 cases. We advise standardizing the procedure to facilitate the reproducibility of this technique.

Single-incision sleeve gastrectomy using a novel technique for liver retraction.

INTRODUCTION: Laparoscopic sleeve gastrectomy has rapidly gained popularity in the field of bariatric surgery, mainly due to its low morbidity and mortality. Traditionally, 4 to 6 trocars are used. Single-access surgery has emerged as an attempt to decrease incisional morbidity and enhance cosmetic benefits. We present our initial 7 patients undergoing single-incision laparoscopic sleeve gastrectomy using a novel technique for liver retraction. METHODS: Patients who underwent single-incision laparoscopic sleeve gastrectomy between March 2009 and May 2009 were analyzed. A 4-cm left paramedian incision was used. Laparoscopic sleeve gastrectomy was performed in a standard fashion using a 40 French bougie. RESULTS: Seven patients underwent single-incision sleeve gastrectomy at the University of Illinois at Chicago. They were all female with a mean age of 34 years. Preoperative BMI was 49 kg/m² (range, 39 to 64). There were no intraoperative complications. Mean operative time was 103 minutes. Estimated blood loss was minimal. All 7 patients were discharged on postoperative day 2 and were doing well without any complications at 3.1 ± 0.7 months after surgery. CONCLUSION: Single-incision laparoscopic sleeve gastrectomy is safe and feasible and can be performed without changing the existing principles of the procedure. Our technique for internal liver retraction provides adequate exposure and is reproducible. Development of improved standard instrumentation is required for this technique to become popular.

Robotic-assisted Heller myotomy versus laparoscopic Heller myotomy for the treatment of esophageal achalasia: multicenter study.

Laparoscopic Heller myotomy (LHM) has become the standard treatment option for achalasia. The incidence of esophageal perforation reported is about 5%-10%. Robotically assisted Heller myotomy (RAHM) is emerging as a safe alternative to LHM. Data comparing the two approaches are scant. The aim of this study was to compare RAHM with LHM in terms of efficacy and safety for treatment of achalasia. A total of 121 patients underwent surgical treatment of achalasia at three institutions. A retrospective review of prospectively collected perioperative data was performed. Patients were divided into two groups: group A (RAHM), 59 patients, and group B (LHM), 62 patients. All the operations were completed using minimally invasive techniques. There were 63 women and 58 men, with a mean age of 45 +/- 19 years (14-82 years). Fifty-one percent of patients in group A and 95% of patients in group B reported weight loss. Duration of symptoms was equal for both groups. Dysphagia was the main complaint in both groups (P = NS). There was no difference in preoperative endoscopic treatment in both groups (44% versus 27%, P = NS). Operative time was significantly shorter for LHM in the first half of the experience (141 +/- 49 versus 122 +/- 44 minutes, P < .05). However, in the last 30 cases there was no difference in operative time between the groups (P = NS). Intraoperative complications (esophageal perforation) were more frequent in group B (16% versus 0%). The incidence of postoperative heartburn did not differ by group. There were no deaths. At 18 and 22 months, 92% and 90% of patients had relief of their dysphagia. This study suggests that RAHM is safer than LHM, because it decreases the incidence of esophageal perforation to 0%, even in patients who had previous treatment. At short-term follow-up, relief of dysphagia was equally achieved in both groups

Spectrum of esophageal motility disorders: implications for diagnosis and treatment.

BACKGROUND: The named primary esophageal motility disorders (PEMDs) are achalasia, diffuse esophageal spasm (DES), nutcracker esophagus (NE), and hypertensive lower esophageal sphincter (HTN-LES). Although the diagnosis and treatment of achalasia are well defined, such is not the case with the other disorders. HYPOTHESIS: (1) Symptoms do not reliably distinguish PEMDs from gastroesophageal reflux disease; (2) esophageal function tests are essential to this distinction and to identifying the type of PEMD; (3) minimally invasive surgery is effective for each condition; and (4) the laparoscopic approach is better than the thoracoscopic approach. DESIGN: University hospital tertiary care center. SETTING: Retrospective review of a prospectively collected database. PATIENTS AND METHODS: A diagnosis of PEMD was established in 397 patients by esophagogram, endoscopy, manometry, and pH monitoring. There were 305 patients (77%) with achalasia, 49 patients (12%) with DES, 41 patients (10%) with NE, and 2 patients (1%) with HTN-LES. Two hundred eight patients (52%) underwent a myotomy by either a thoracoscopic or a laparoscopic approach. RESULTS: Ninety-nine patients (25%) had a diagnosis of gastroesophageal reflux disease at the time of referral and had been treated with acid-suppressing medications. In achalasia and DES, a thoracoscopic or laparoscopic myotomy relieved dysphagia and chest pain in more than 80% of the patients. In contrast, in NE the results were less predictable, and the operation most often failed to relieve symptoms. CONCLUSIONS: These results show that (1) symptoms were unreliable in distinguishing gastroesophageal reflux disease from PEMDs; (2) esophageal function tests were essential to diagnose PEMD and to define its type; (3) the laparoscopic approach was better than the thoracoscopic approach; (4) a laparoscopic Heller myotomy is the treatment of choice for achalasia, DES, and HTN-LES; and (5) a predictably good treatment for NE is still elusive, and the results of surgery were disappointing.

Total fundoplication is superior to partial fundoplication even when esophageal peristalsis is weak.

BACKGROUND: About a decade ago, partial (240 degrees) fundoplication became popular for treating gastroesophageal reflux disease in cases where the patient's primary esophageal peristalsis was weak. A total (360 degrees) fundoplication was reserved for patients with normal peristalsis (tailored approach). The theory was that partial fundoplication was an adequate antireflux measure, and by posing less resistance for the weak esophageal peristalsis to overcome, it would give rise to less dysphagia. Short-term results seemed to confirm these ideas. STUDY DESIGN: This study reports the longterm followup of patients in whom a tailored approach (type of wrap chosen to match esophageal peristalsis) was used, and the results of a nonselective approach, using a total fundoplication regardless of the amplitude of esophageal peristalsis. We analyzed clinical and laboratory findings in 357 patients who had an operation for gastroesophageal reflux disease between October 1992 and November 2002. Group 1 was composed of 235 patients in whom a tailored approach was used between October 1992 and December 1999 (141 patients, partial fundoplication and 94 patients, total fundoplication). Group 2 contained 122 patients in whom a nonselective approach was used (total fundoplication regardless of quality of peristalsis). RESULTS: In group 1, heartburn from reflux (ie, pH monitoring test was abnormal) recurred in 19% of patients after partial fundoplication and in 4% after total fundoplication. In group 2, heartburn recurred in 4% of patients after total fundoplication. The incidence of postoperative dysphagia was similar in the two groups. CONCLUSIONS: These data show that laparoscopic partial fundoplication was less effective than total fundoplication in curing gastroesophageal reflux disease, and compared with a partial (240 degrees) fundoplication, a total (360 degrees) fundoplication was not followed by more dysphagia, even when esophageal peristalsis was weak.

Achalasia and chest pain: effect of laparoscopic Heller myotomy.

Some patients with achalasia complain of chest pain in addition to dysphagia and regurgitation. Chest pain is said to be most common in young patients who have been symptomatic for a short time, and who often have vigorous achalasia (distal esophageal amplitude >/=37 mm Hg). Although pneumatic dilatation is reported to improve chest pain in 20% of patients, the effect of laparoscopic Heller myotomy on chest pain is unknown. The aim of this study was to determine the following in achalasia: (1) the prevalence of chest pain; (2) the clinical and manometric profiles of patients with chest pain; and (3) the effect of laparoscopic Heller myotomy. Between 1990 and 2001, a total of 211 patients with achalasia were studied (upper gastrointestinal series, esophagoduodenoscopy, and manometry). A total of 117 patients (55%) had chest pain in addition to dysphagia and regurgitation; 63 (54%) of these 117 patients underwent laparoscopic Heller myotomy and Dor fundoplication. Median follow up was 24 months. Age (49+/-16 years vs. 51+/-14 years [mean+/-SD]), duration of symptoms (71+/-91 months vs. 67+/-92 months [mean+/-SD]), and presence of vigorous achalasia (50% vs. 47%) were similar in those with and without chest pain. Ten (16%) of the 63 patients with chest pain who underwent Heller myotomy had vigorous achalasia. Postoperatively chest pain resolved in 84% and improved in 11% of patients. There was no difference in clinical outcome between patients with and without vigorous achalasia. These data demonstrate the following: (1) chest pain was present in 55% of patients with esophageal achalasia; (2) chest pain was not related to age, duration of symptoms, or manometric findings; and (3) laparoscopic Heller myotomy improved chest pain in 95% of patients, regardless of the manometric findings. Thus laparoscopic Heller myotomy was highly effective in treating achalasia with chest pain.

Impact of minimally invasive surgery on the treatment of esophageal achalasia: a decade of change.

BACKGROUND: Twenty years ago an average of 1.5 Heller myotomies were performed per year in our hospital, mostly for patients whose dysphagia did not improve following balloon dilatation or whose esophagus had been perforated during a balloon dilatation. Ten years ago we started using minimally invasive surgery to treat this disease. STUDY DESIGN: This study measures the impact of minimally invasive surgery with regard to the following: the number of patients referred for treatment; the number of patients who came to surgery without previous treatment; and the results of surgical treatment. Between 1991 and 2001, 149 patients had minimally invasive surgery for achalasia: 25 patients (17%) had thoracoscopic Heller myotomy and 124 (84%) had laparoscopic Heller myotomy and Dor fundoplication. Of the 149 patients, 79 patients (53%) had previous treatment (56 patients [71%], balloon dilatation; 7 patients [9%], botulinum toxin injection; 16 patients [20%], both) and 70 patients (43%) had none of these treatments. Mean postoperative followup was 59 +/- 36 months. Patients were divided into two groups: group A, operated on between 1991 and 1995; and group B, operated on between 1996 and 2001. RESULTS: In the past decade, the number of patients referred for surgery has increased substantially--group A, 48; group B, 101; an increasing proportion of patients were referred for surgery without previous treatment--group A, 38%; group B, 51%; and the outcomes of the operation progressively improved--group A, 87%; group B, 95%. CONCLUSIONS: These data show that the high success rate of laparoscopic Heller myotomy for achalasia has brought a shift in practice; surgery has become the preferred treatment of most gastroenterologists and other referring physicians. This has followed documentation that laparoscopic treatment outperforms balloon dilatation and botulinum toxin injection.

Symptoms are a poor indicator of reflux status after fundoplication for gastroesophageal reflux disease: role of esophageal functions tests.

BACKGROUND: If a patient develops foregut symptoms after a fundoplication, it is assumed that the operation has failed, and acid-reducing medications are often prescribed. Esophageal function tests (manometry and pH monitoring) are seldom performed early in the management of these patients. HYPOTHESIS: In patients who are symptomatic after fundoplication for gastroesophageal reflux disease, a symptom-based diagnosis is not accurate, and esophageal function tests should be performed routinely before starting acid-reducing medications. DESIGN: Prospective study. SETTING: University hospital. PATIENTS AND METHODS: One hundred twenty-four patients who developed foregut symptoms after laparoscopic fundoplication (average, 17 months postoperatively) underwent esophageal manometry and pH monitoring. Sixty-two patients (50%) were taking acid-reducing medications. MAIN OUTCOME MEASURES: Postoperative symptoms, use of antireflux medications, grade of esophagitis, esophageal motility, and DeMeester scores. RESULTS: Seventy-six (61%) of the 124 patients had normal esophageal acid exposure, while the acid exposure was abnormal in 48 patients (39%). Only 20 (32%) of the 62 patients who were taking acid-reducing medications had reflux postoperatively. Regurgitation was the only symptom that predicted abnormal reflux. CONCLUSIONS: These results show that (1) symptoms were due to reflux in 39% of patients only; (2) with the exception of regurgitation, symptoms were an unreliable index of the presence of reflux; and (3) 68% of patients who were taking acid-reducing medications postoperatively had a normal reflux status. Esophageal function tests should be performed early in the evaluation of patients after fundoplication to avoid improper and costly medical therapy.

Laparoscopic treatment of recurrent dysphagia following transthoracic myotomy for achalasia.

BACKGROUND: The choice of treatment of recurrent dysphagia following transthoracic myotomy is unclear. Often pneumatic dilatation is tried first, followed by esophagectomy in case of failure. We propose laparoscopic Heller myotomy as an alternative treatment for this group of patients. METHODS: Three patients underwent laparoscopic Heller myotomy for the treatment of recurrent dysphagia following transthoracic myotomy. The patients had undergone an average of 7 pneumatic dilatations (range, 2 to 10) prior to referral for surgery, without resolution of their dysphagia. RESULTS: All patients successfully underwent a laparoscopic myotomy on the right side of the esophagus with a Dor fundoplication. Good or excellent results were achieved in all patients. Average followup was 18 months. CONCLUSIONS: Laparoscopic Heller myotomy is a very effective treatment for patients who experience recurrent dysphagia following a transthoracic myotomy.
