RESUMEN

BACKGROUND: To evaluate the use of a double loop reconstruction following pylorus preserving proximal pancreaticoduodenectomy (PPPPD). METHODS: Morbidity and mortality were evaluated in 55 patients undergoing PPPPD for malignant tumors, followed by a double loop reconstruction. RESULTS: The mean intra-operative blood loss was 908mL±531. In-hospital mortality was 5.4% (3/55 pts). The mean length of hospital stay was 17±5 days (range 12-45 days). Postoperative complications occurred in 25 patients (46.2%). Five patients developed an anastomotic leak, one biliary and four pancreatic (4/55; 7%). Delayed gastric emptying occurred in 8 patients (14.5%). Reoperation was required in two patients for hemorrhage. CONCLUSIONS: A double loop alimentary reconstruction following PPPPD led to a low incidence of DGE and pancreatic fistula. Although mortality rate was higher than that reported by referral centres, this technique has been performed in a not specialized unit attaining acceptable results.

RESUMEN

BACKGROUND: Sleeve gastrectomy (SG) is currently gaining popularity due to an excellent efficacy combined to minimal anatomic changes. However, some concerns have been raised on increased risk of postoperative gastroesophageal reflux disease (GERD) due to gastric fundus removal, section of the sling muscular fibers of gastroesophageal junction, reduced antral pump function, and gastric volume. We undertook the current study to evaluate by means of high-resolution impedance manometry (HRiM) and combined 24-h pH and multichannel intraluminal impedance (MII-pH) the impact of SG on esophageal physiology. METHODS: In this study, 25 consecutive patients had HRiM and MII-pH before and after laparoscopic SG. The following parameters were calculated at HRiM: lower esophageal sphincter (LES) pressure and relaxation, peristalsis, number of complete esophageal bolus transit, and mean total bolus transit time. The acid and non-acid GER episodes were assessed by MII-pH with the patient in both upright and recumbent positions. RESULTS: At a median follow-up of 13 months, HRiM showed an unchanged LES function, increased ineffective peristalsis, and incomplete bolus transit. MII-pH showed an increase of both acid exposure of the esophagus and number of non-acid reflux events in postprandial periods. CONCLUSIONS: Laparoscopic SG is an effective restrictive procedure that creates delayed esophageal emptying without impairing LES function. A correctly fashioned sleeve does not induce de novo GERD. Retrograde movements and increased acid exposure are probably due to stasis and postprandial regurgitation.

RESUMEN

Identifying and treating patients with extra-esophageal symptoms is a challenge. When the patient is unable to control his symptoms with pharmacological therapy alone, anti-reflux surgery may be indicated. This study aims to evaluate the outcomes of total fundoplication in the resolution of extra-esophageal manifestations and verify changes in 24-h MII-pH monitoring before and after surgery. From October 2005 to October 2010, patients who reported respiratory symptoms, possibly related to GERD, have been sent to our Institute. All patients were practiced ambulatory 24-h MII-pH before and after surgery. Thirty-five patients selected for the antireflux surgery have undergone all the same surgical procedures. Data were collected prospectively at 6 and 12 months after laparoscopic fundoplication. After laparoscopic fundoplication, the total percentage of exposure time with esophageal pH < 4, and both in upright and supine position was very low. A statistically significant difference (p < 0.05) was found in the number of detected refluxes at MII and detected refluxes at MII 15-cm segment in pre and post-operative period. Symptom relief was obtained in all patients. Laparoscopic fundoplication is a safe and effective procedure to protect from refractory GERD and extra-esophageal symptoms, when evaluated with a thorough pre-operative selection.

RESUMEN

BACKGROUND: Laparoscopic total fundoplication is considered the most effective surgical option for gastroesophageal reflux (GER) disease. Some authors assume that total fundoplication may expose the patient to delayed transit of the swallowed bolus and increased risk of dysphagia, particularly when peristaltic dysfunction is present. We undertook this study to evaluate by means of combined multichannel intraluminal impedance and esophageal manometry (MII-EM) the impact of fundoplication on esophageal physiology. An objective measurement of the influence of the total wrap on bolus transit may be helpful in refining the optimal antireflux wrap (ie, partial vs. total). METHODS: In this study, 25 consecutive patients who underwent laparoscopic Nissen-Rossetti fundoplication had MII-EM and combined 24-hour pH and multichannel intraluminal impedance (MII-pH) before and after the surgical procedure. All patients completed preoperative and postoperative symptom questionnaires. The following were calculated for liquid and viscous deglutition lower esophageal sphincter pressure and relaxation, distal esophageal amplitude, the number of complete esophageal bolus transits and the mean total bolus transit time. The acid and nonacid GER episodes were calculated by MII-pH with the patient in both upright and recumbent positions. RESULTS: The postoperative MII-EM showed an increased lower esophageal sphincter pressure (P < 0.05), whereas lower esophageal sphincter relaxation and distal esophageal amplitude did not change after surgery (P = NS). Complete esophageal bolus transits and bolus transit time did not change for liquid swallows (P = NS), but was more rapid for viscous after surgery (P < 0.05). Twenty-four hour pH monitoring confirmed the postoperative reduction of both acid and nonacid reflux (P < 0.05). CONCLUSIONS: Laparoscopic Nissen-Rossetti is effective in controlling both acid and nonacid GER without impairment of esophageal function. Appropriate preoperative investigation, meticulous patient selection and correct surgical technique are extremely important in securing good results.

RESUMEN

We evaluated the association of a weekly cisplatin (35 mg/mq) and paclitaxel (45 mg/mq) regimen with radiotherapy (46 Gy) as primary treatment in locally advanced esophageal cancer (LAEC). The main end point was the activity in terms of pathologic complete response (pathCR) rate. Thirty-three LAEC patients received chemoradiation therapy during weeks 1-6 followed by esophagectomy. A pathCR was observed in 10/33 patients; 20/33 and 3/33 patients showed PR and SD, respectively. The EUS maximal transverse cross sectional area reduction >50% significantly correlated with pathCR. Three-year survival rate was 35%. These results support the activity and mild toxicity of this regimen.

RESUMEN

BACKGROUND: Adjuvant chemoradiotherapy does not represent the standard of care in patients with resected high-risk gastric cancer; however, results from phase 2 and randomized trials suggest improvement in overall survival. We assessed the feasibility and toxic effects of chemoradiotherapy as adjuvant treatment in locally advanced gastric cancer. DESIGN: Pilot study. SETTING: University hospital. PATIENTS: Twenty-nine patients with T4N+ or any TN23 gastric cancer previously treated with potentially curative surgery were enrolled. All of the patients received combined adjuvant chemotherapy with FOLFOX-4 (ie, a combination of folinic acid [leucovorin], fluorouracil, and oxaliplatin [Eloxatin]) for 8 cycles and concomitant radiotherapy (45 Gy in 25 daily fractions over 5 weeks). Radiotherapy was begun after the first 2 cycles of FOLFOX-4, which was reduced by 25% during the period of concomitant radiotherapy. MAIN OUTCOME MEASURES: Treatment toxic effects according to the National Cancer Institute-Common Toxicity Criteria classification, overall and disease-free survival rates, and identification of prognostic indicators. RESULTS: All of the patients completed treatment. Severe hematologic and gastrointestinal toxic effects occurred in 10% and 33%, respectively. No acute hepatic or renal toxic effects were observed; 1 patient experienced severe neurotoxicity. Disease-free and overall survival rates at 1, 2, and 3 years were 79%, 35%, and 35% and 85%, 62.6%, and 50.1%, respectively, and were shown to be substantially better than those observed in untreated patients. Long-term outcome was related to TNM stage, basal serum tumor marker level, and, particularly, lymph node ratio. CONCLUSION: A multimodal approach with FOLFOX-4 and radiotherapy is feasible and effective for the treatment of patients with resected high-risk gastric cancer.

RESUMEN

INTRODUCTION: Although laparoscopic Nissen fundoplication has been recognized as the standard of care for hiatal hernia (HH) repair, HH recurrence due to breakdown of the hiatoplasty have been reported as a common mechanism of failure after primary repair. Different surgical techniques for diaphragmatic pillars closure have been proposed, but the problem remains unsolved. The authors hypothesized that ultrastructural illness may be implicated in this recurrence. The aim of this study was to investigate the presence of changes at esophageal hiatal area in patients with and without HH. MATERIALS AND METHODS: One hundred and thirty-two laparoscopic samples from phrenoesophageal membrane and diaphragmatic crura were collected from 33 patients with gastroesophageal reflux disease and HH (HH group) and 60 samples from 15 patients without HH enrolled as the control group (NHH group). All specimens were processed and analyzed by transmission electron microscopy. RESULTS: Muscular and connective samples from the NHH group showed no ultrastructural alterations; similar results were found in phrenoesophageal ligament samples from the HH group. In contrast, 94% of the muscular samples obtained from the crura of the HH group have documented four main types of alterations. In 75% of HH patients, the pillar lesions were severe. CONCLUSION: Patients with hiatal hernia have ultrastructural abnormalities at the muscular tissue of the crura that are not present in patients with a normal gastroesophageal junction. There is no difference in the microscopic damage at the connective tissue of the phrenoesophageal membrane surrounding the esophagus of the two groups of patients. The outcome of antireflux surgery could depend not only on the adopted surgical technique but also on the underlying status of the diaphragmatic crura.

RESUMEN

Laparoscopic Heller myotomy with antireflux procedure seems the procedure of choice in the treatment of patients with esophageal achalasia. Persistent or recurrent symptoms occur in 10% to 20% of patients. Few reports on reoperation after failed Heller myotomy have been published. No author has reported the realization of a total fundoplication in these patient groups. The aim of this study is to evaluate the efficacy of laparoscopic reoperation with the realization of a total fundoplication after failed Heller myotomy for esophageal achalasia. From 1992 to December 2007, 5 out of a series of 242 patients (2.1%), along with 2 patients operated elsewhere, underwent laparoscopic reintervention for failed Heller myotomy. Symptoms leading to reoperation included persistent dysphagia in 3 patients, recurrent dysphagia in another 3, and heartburn in 1 patient. Mean time from the first to the second operation was 49.7 months (range, 4-180 months). Always, the intervention was completed via a laparoscopic approach and a Nissen-Rossetti fundoplication was realized or left in place after a complete Heller myotomy. Mean operative time was 160 minutes (range, 60-245 minutes). Mean postoperative hospital stay was 3.1 +/- 1.5 days. No major morbidity or mortality occurred. At a mean follow-up of 16.1 months, reoperation must be considered successful in 5 out of 7 patients (71.4%). The dysphagia DeMeester score fell from 2.71 +/- 0.22 to 0.91 +/- 0.38 postoperatively. The regurgitation score changed from 2.45 +/- 0.34 to 0.68 +/- 0.23. Laparoscopic reoperation for failed Heller myotomy with the realization of a total fundoplication is safe and is associated with good long-term results if performed by an experienced surgeon in a center with a long tradition of esophageal surgery.

RESUMEN

OBJECTIVE: To define the frequency and predictors of short esophagus in a case series of patients undergoing antireflux surgery. METHOD: An observational prospective study from September 10, 2004, to October 31, 2006, was performed at 8 centers. The distance between the esophagogastric junction as identified by intraoperative esophagoscopy and the apex of the diaphragmatic hiatus was measured intraoperatively before and after esophageal mediastinal dissection; a distance of 1.5 cm was arbitrarily determined to categorize cases as long (>1.5 cm) or short (

RESUMEN

INTRODUCTION: Selecting gastroesophageal reflux disease (GERD) patients for surgery on the basis of standard 24-h pH monitoring may be challenging, particularly if this investigation does not correlate with clinical symptoms. Combined multichannel intraluminal impedance pH monitoring (MII-pH) is able to physically detect each episode of intraesophageal bolus movements, enabling identification of either acid or non-acid reflux episodes and thus establish the association of the reflux with symptoms. MATERIALS AND METHODS: We prospectively assessed and reviewed data from 314 consecutive patients who underwent MII-pH for GERD not responsive or not compliant to proton pump inhibitor therapy. One hundred fifty-three patients with a minimum follow-up of 1 year constituted the study population. Clinical outcomes and satisfaction rate were collected in all patients who underwent laparoscopic Nissen-Rossetti fundoplication. Outcomes were reported for patients with normal and ineffective peristalsis and for patients with positive pH monitoring, negative pH monitoring and positive total number of reflux episodes at MII, and negative pH monitoring and normal number of reflux episodes at MII and a positive symptom index correlation with MII. RESULTS: The overall patient satisfaction rate was 98.3%. No differences were recorded in the clinical outcomes of the patients with preoperative normal and ineffective peristalsis. No differences in patients' satisfaction and clinical postoperative DeMeester symptom scoring system were noted between the groups as determined by MII-pH. CONCLUSION: MII-pH provides useful information for objective selection of patients to antireflux surgery. Nissen fundoplication provides excellent outcomes in patients with positive and negative pH and positive MII monitoring or Symptom Index association. More extensive studies are needed to definitively standardize the useful MII-pH parameters to select the patient to antireflux surgery.

RESUMEN

BACKGROUND: One limit of the Roux-en-Y gastric bypass (GBP) is the preclusion of exploring the bypassed stomach with conventional endoscopy and radiological studies. In this study, we explored the feasibility, safety, and weight progression of a new bariatric procedure that eliminates this inconvenience. METHODS: Eleven 40- to 50-kg Yorkshire pigs underwent laparoscopic sleeve gastrectomy and Roux-en-Y duodeno-jejunal bypass (SG-DJBP). Weight was monitored at postoperative days 15 and 30 and after 3 months; weight progression was compared with an identical group that underwent a sham procedure or GBP. At autopsy, surgical site was evaluated at microscopic and macroscopic level. RESULTS: Mean operating time was 66 +/- 5.76 min. All the survivors tolerated the procedure well, except one subject that experienced a gastric leak from the stapler line. The SG-DJBP had a had significantly slower weight gains than the sham group (P = 0.005). The absence of histological abnormalities in the duodenal wall was confirmed at autopsy. CONCLUSION: SG-DJBP is feasible and produces effects of weight progression comparable to those of GBP. Being a combination of previously standardized procedures, we are confident to propose this procedure as a bariatric alternative in humans. Long-term follow-up will be required to establish the efficacy on weight loss in humans.

RESUMEN

BACKGROUND: We investigated which factors are significantly associated with long-term quality of life after laparoscopic total fundoplication in the treatment of gastroesophageal reflux disease. METHODS: Patients (n = 144) were given a standardized frequency-intensity symptoms questionnaire and the Short-Form 36 Health Survey for quality-of-life evaluation before and after laparoscopic total fundoplication. RESULTS: At follow-up evaluation (n = 102), patients had a significant reduction in their symptoms score and no deterioration in quality of life. A significant association with postoperative dysphagia for solids and/or liquids was found in the physical component summary score of the Short-Form 36 administered to patients postoperatively (P = .003). CONCLUSIONS: In this study, laparoscopic total fundoplication was a safe and effective surgical treatment for gastroesophageal reflux disease, generally offering an improved long-term quality of life, with the exception of a minority of patients (6 of 102 patients; 5.8%) who experienced persistent severe dysphagia.

RESUMEN

BACKGROUND: The realisation of bariatric surgery has to date modified the digestive process solely through procedures within the abdominal cavity. However, endocrine surgeons have recently demonstrated the feasibility of a minimally invasive approach to the neck. In this study, we explored the feasibility, safety and weight progression of a bariatric procedure performed at the neck. METHODS: Eleven 40-50 kg Yorkshire pigs underwent endoscopic placement of an adjustable band to the cervical esophagus (ECB). Weight was monitored at postoperative days 15, 30, and after 7 weeks; weight progression was compared with an identical group of pigs who underwent a sham procedure. At autopsy, the surgical site was evaluated in a microscopic and macroscopic manner. RESULTS: Mean operating time was 66 +/- 5.76 min. All pigs tolerated the procedure well, except one subject that experienced food intolerance. The ECB group experienced significantly slower weight gain than the sham group (P = 0.005). Proper location of the band and absence of microscopic lesions at the esophageal wall were confirmed at autopsy and pathological examination. CONCLUSION: Bariatric surgery at the neck is feasible and produces effects on weight reduction. Further refinements and longer observation periods are required to propose this procedure as safe and effective alternative in humans.

RESUMEN

BACKGROUND: Studies have demonstrated that Nissen fundoplication controls acid gastroesophageal reflux (GER). Combined 24-h pH and multichannel intraluminal impedance (MII-pH) allows detection of both acid and nonacid GER. Antireflux surgery is considered for any patient whose medical therapy is not efficient, particularly patients with nonacid gastroesophageal reflux disease (GERD). Nevertheless, fundoplication used to control nonacid reflux has not been reported to date. METHODS: In this study, 15 consecutive patients who underwent laparoscopic Nissen-Rossetti fundoplication had MII-pH both before and after the surgical procedure. The numbers of acid and nonacid GER episodes were calculated with the patient in both upright and recumbent positions. RESULTS: The 24-h pH monitoring confirmed the postoperative reduction of exposure to acid (p < 0.05). Postoperatively, the total, acid, and nonacid numbers of GER episodes were reduced (p < 0.05). CONCLUSION: According to the findings, MII-pH is feasible and well tolerated. It provides an objective means for evaluating the effectiveness of Nissen-Rossetti fundoplication in controlling both acid and nonacid GER.

RESUMEN

There are different surgical possibilities for the treatment of oesophageal achalasia ranging from a short extramucosal oesophagomyotomy to an extended esophago-gastric myotomy combined with a partial fundoplication to restore the main antireflux barrier. A total 360 degrees fundoplication is generally regarded as an obstacle to oesophageal emptying. The aim of this study was to evaluate the role and efficacy of total 360 degrees laparoscopic Nissen-Rossetti fundoplication after oesophago gastric myotomy in the treatment of oesophageal achalasia. From 1992 to January 2008, a total of 245 patients (112 males, 133 females), mean age 45.1 years (range: 12-79), were submitted to laparoscopic Nissen-Rossetti fundoplication after a Heller myotomy with endoscopic and manometric intraoperative monitoring. In 3 patients (1.2%), conversion to laparotomy was necessary. Mean operative time was 60 +/- 15 minutes. No mortality was observed. The overall morbidity rate was 1.6%. The mean postoperative hospital stay was 3.5 +/- 1.0 days (range: 1-12 days). A mean clinical follow-up of 100.2 +/- 7 months (range: 3-177) was possible for 228 patients (93.1%), and an excellent or good outcome was observed in 209 patients (91.7%) (DeMeester dysphagia score 0-1). No improvement in dysphagia was observed in 5 (2.2%) patients. Pathological gastro-oesophageal reflux was absent in all patients. Laparoscopic Nissen-Rossetti fundoplication after a Heller myotomy is a safe, effective treatment for oesophageal achalasia with excellent results in terms of dysphagia resolution, affording total protection from the onset of gastrooesophageal reflux.

RESUMEN

Duodenogastric reflux (DGR) is barely responsive to medications and antireflux fundoplication is not able to control the gastric symptoms. Duodenal switch (DS) preserves the physiologic food transit while creating an effective Roux-en-Y diversion to duodenal juice. However, it never enjoyed great popularity, perhaps due to the invasiveness of the open approach. The paper reports our initial experience with laparoscopic DS. Preoperative assessment, surgical technique, and outcomes are described. Normalization of DGR was demonstrated by preoperative and postoperative 24-hour bilimetry and pH-multichannel intraluminal impedance. The procedure was completed under laparoscopy in all the cases with a mean operative time of 165 minutes. Mean blood loss was 200 mL. No patient required admission to the intensive care unit. Initial experience with laparoscopic DS encourages continued use of the minimally invasive approach. A meticulous preoperative evaluation is essential to place a correct indication.

RESUMEN

BACKGROUND: Bariatric surgery is considered the most effective treatment for reducing excess body weight and maintaining weight loss (WL) in severely obese patients. There are limited data evaluating metabolic and body composition changes after different treatments in type III obese (body mass index [BMI] > 40 kg/m(2)). METHODS: Twenty patients (9 males, 11 females; 37.6 +/- 8 years; BMI = 50.1 +/- 8 kg/m(2)) treated with dietary therapy and lifestyle correction (group 1) have been compared with 20 matched patients (41.8 +/- 6 years; BMI = 50.4 +/- 6 kg/m(2)) treated with laparoscopic gastric bypass (LGBP; group 2). Patients have been evaluated before treatment and after >10% WL obtained on average 6 weeks after LGBP and 30 weeks after integrated medical treatment. Metabolic syndrome (MS) was evaluated using the Adult Treatment Panel III/America Heart Association (ATP III/AHA) criteria. Resting metabolic rate (RMR) and respiratory quotient (RQ) was assessed with indirect calorimetry; body composition with bioimpedance analysis. RESULTS: At entry, RMR/fat-free mass (FFM) was 34.2 +/- 7 kcal/24 h.kg in group 1 and 35.1 +/- 8 kcal/24 h.kg in group 2 and did not decrease in both groups after 10% WL (31.8 +/- 6 vs 34.0 +/- 6). Percent FFM and fat mass (FM) was 50.7 +/- 7% and 49.3 +/- 7% in group 1 and 52.1 +/- 6% and 47.9 +/- 6% in group 2, respectively (p = n.s.). After WL, body composition significantly changed only in group 1 (% FFM increased to 55.9 +/- 6 and % FM decreased to 44.1 +/- 6; p = 0.002). CONCLUSION: After >10% WL, MS prevalence decreases precociously in surgically treated patients; some improvements in body composition are observed in nonsurgically treated patients only. Further investigations are needed to evaluate long-term effects of bariatric surgery on body composition and RMR after stable WL.

RESUMEN

After esophagectomy, the stomach is usually used to restore digestive continuity. To prevent postoperative delayed gastric emptying, most authors perform a gastric drainage procedure or transpose a tubulized stomach. The aim of our work is to evaluate the emptying of a transposed whole stomach without performing a pyloromyotomy or a pyloroplasty. From 1996 to January 2004, 45 patients underwent total esophagectomy for cancer or for caustic stenosis. Reconstruction of digestive continuity was realized through transposition of the whole stomach without performing a pyloric drainage procedure. At 12 months after the intervention, 35 patients (77.8%; 20 men and 15 women) were submitted to a gastric emptying scintigraphic study by means of ingestion of a mixed meal labeled with 37 MBq 99mTc-sulfur colloid. Mean half-emptying time was 71.4 minutes (range, 15-90 minutes; reference range, 83 +/- 34 minutes): all the patients were in the normal range except one. No patient complained of delayed gastric emptying symptoms. After esophagectomy, the transposition of the whole stomach without a pyloric drainage procedure seems to be an interesting option, and is not associated with delayed gastric emptying.

RESUMEN

Some achalasia patients do not ameliorate dysphagia after Heller myotomy. If stenosis does not respond to endoscopic dilatations and persists after a second extended myotomy, an esophageal resection is considered unavoidable. This article describes an original technique of treating this type of persistent stenosis with an esophageal stricturoplasty. The procedure was completed under laparoscopy. The postoperative course was uneventful. Resolution of all preoperative symptoms was achieved at the first year follow-up. Control of gastroesophageal reflux was documented by 24-hour pH-impedance. If confirmed by further cases, laparoscopic esophageal stricturoplasty could become a valid option for a conservative treatment of these patients.

RESUMEN

BACKGROUND: Several different ways of fashioning a total fundoplication lead to different outcomes. This article addresses the technical details of the antireflux technique we adopted without modifications for all patients with GERD beginning in 1972. In particular it aims to discuss the relation between the mechanism of function of the wrap and the physiology of the esophagus. METHODS: The study population consisted of 380 patients affected by GERD with a 1-year minimum of follow-up who underwent laparoscopic Nissen-Rossetti fundoplication by a single surgeon. RESULTS: No conversion to open surgery and no mortality occurred. Major complications occurred in 4 patients (1.1%). Follow-up (median 83 months; range: 1-13 years) was achieved in 96% of the patients. Ninety-two percent of the patients were satisfied with the results of the procedure and would undergo the same operation again. Postoperative dysphagia occurred in 3.5% of the patients, and recurrent heartburn was observed in 3.8%. CONCLUSIONS: Laparoscopic Nissen-Rossetti fundoplication with the routine use of intraoperative manometry and endoscopy achieved good outcomes and long-term patient satisfaction with few complications and side-effects. Appropriate preoperative investigation and a correct surgical technique are important in securing these results.
