Superior Mesenteric Artery Syndrome: a Prospective Study in a Single Institution.

BACKGROUND: Superior mesenteric artery syndrome (SMAS) is a rare cause of duodenal obstruction, resulting from the compression of the duodenum between superior mesenteric artery and aorta. This prospective registry aims to describe demographic, clinical, and outcome features of patients suffering from SMAS and to point out the indications for surgery. METHODS: Between 2008 and 2016, patients with chronic gastrointestinal symptoms and diagnosis of SMAS were included. Demographics, clinical presentation, diagnosis, and surgical outcome were recorded. Symptoms were investigated with a standardized questionnaire. The diagnosis was achieved through barium swallow, CT/MR angiography (aortomesenteric angle ≤ 22°, distance ≤ 8 mm), endoscopy. All patients underwent duodenojejunostomy ± distal duodenum resection. At follow-up, symptom score and barium swallow were re-evaluated. RESULTS: Thirty-nine patients (11 M/28 F, median age 38 years, median BMI 17.8 kg/m2) were included. Barium swallow showed a gastroduodenal dilation in 57% of patients, and a delayed gastroduodenal emptying in 38%. Median aortomesenteric angle was 11° and distance was 5 mm. All patients underwent duodenojejunostomy, and in 32 patients, a distal duodenum resection was also performed. At a median follow-up of 47 months, the overall symptom score significantly dropped (10 vs. 32, p < 0.0001) and BMI increased (19.5 vs. 17.8, p < 0.0001). Barium swallow at 2 months postoperatively showed an improvement in terms of gastroduodenal dilation and emptying in 38% of patients with preoperative pathological findings. CONCLUSIONS: SMAS is a rare condition that should be suspected in cases of chronic, refractory upper digestive symptoms, particularly in females with low BMIs. Surgical treatment may improve symptoms and quality of life, although it is not curative in all cases. ClinicalTrials.gov Identifier: NCT03416647.

A modified Nissen fundoplication: subjective and objective midterm results.

PURPOSE: The failure rate of laparoscopic anti-reflux surgery is approximately 10-20%. The aim of our prospective study was to investigate whether a modified Nissen fundoplication (MNF) can improve reflux symptoms and prevent surgical treatment failure in the midterm. METHODS: The MNF consisted of (1) suturing the esophagus to the diaphragmatic crura on each side using four non-absorbable stitches, (2) reinforcing clearly weak crura with a tailored Ultrapro mesh, and (3) fixing the upper stitch of the valve to the diaphragm. Forty-eight consecutive patients experiencing typical gastroesophageal reflux disease (GERD) symptoms at least three times per week for 6 months or longer were assessed before and after surgery using validated symptom and quality of life (GERD-HRQL) questionnaires, high-resolution manometry, 24-h impedance-pH monitoring, endoscopy, and barium swallow. RESULTS: Mortality and perioperative complications were nil. At median follow-up of 46.7 months, the patients experienced significant improvements in symptom and GERD-HRQL scores. One patient presented with severe dyspepsia and another complained of dysphagia requiring a repeat surgery 12 months after the first operation. Esophageal acid exposure (8.8 vs 0.1; p < 0.0001), reflux number (62 vs 8.5; p < 0.0001), and symptom-reflux association (19 vs 0; p < 0.0001) significantly decreased postoperatively. The median esophagogastric junction contractile integral (EGJ-CI) from 31 cases (8.2 vs 21.2 mmHg cm; p = 0.0003) and the abdominal length of the lower esophageal sphincter (LES) (0 vs 16 mm; p = 0.01) increased postoperatively. CONCLUSIONS: Our data demonstrate that the MNF is a safe and effective procedure both in the short term and midterm.

Cost analysis of incisional hernia repair with synthetic mesh and biological mesh: an Italian study.

Repair of an incisional hernia (IH) generates costs on several levels and domains of society. The aim of this study was to make a complete cost analysis of incisional hernia repair (IHR) with synthetic and biological mesh and to compare it with financial reimbursement. Patients were grouped into three levels to determine the complexity of their care, and hence, the costs involved. Group 1 included patients without comorbidities, who underwent a "standard" incisional hernia repair (SIHR), with synthetic mesh. Group 2 included patients with comorbidities, who underwent the same surgical procedure. Group 3 included all patients who underwent a "complex" IHR (CIHR) with biological mesh. Total costs were divided into direct (including preoperative and operative phases) and indirect costs (medications and working days loss). Reimbursement was calculated according to Diagnosis-Related Group (DRG). From 2012 to 2014, 76 patients underwent prosthetic IHR: group 1 (35 pts); group 2 (30 pts); and group 3 (11 pts). The direct costs of preoperative and operative phases for groups 1 and 2 were €5544.25 and €5020.65, respectively, and €16,397.17 in group 3. The total reimbursement in the three groups was €68,292.37 for group 1, €80,014.14 for group 2, and €72,173.79 for group 3, with a total loss of €124,658.43, €69,675.36, and €100,620.04, respectively. All DRGs underestimate the costs related to IHR and CIHR, thus resulting in an important economic loss for the hospital. The cost analysis shows that patient-related risk factors do not alter the overall costs. To provide a correct "cost-based" reimbursement, different DRGs should be created for different types of hernias and prostheses.

A modification of Nissen fundoplication improves patients' outcome and may reduce procedure-related failure rate.

BACKGROUND: Laparoscopic anti-reflux surgery has a failure rate of 10-20%. We aimed to investigate whether a modification of Nissen fundoplication (MNF) may improve patients' outcome and reduce failure rate. MATERIALS & METHODS: We prospectively compared 40 consecutive patients with gastroesophageal reflux disease who underwent anti-reflux surgery: 20 Nissen fundoplication (NF) and 20 the MNF approach. Eight cases in the MNF group needed redo surgery. The MNF consisted in suturing the esophagus to the diaphragmatic crura on each side by means of 4 non-absorbable stitches and in fixing the upper stitch of the valve to diaphragm. In case of clearly weak crura, a reinforcement with Ultrapro mesh was used. All patients were assessed before and after surgery using validated symptoms and quality of life (GERD-HRQL) questionnaires, manometry and 24-h impedance-pH monitoring, endoscopy and barium-swallow. RESULTS: Mortality and postoperative complications were nil. At a median follow-up of 36 months, no significant differences emerged between the MNF and NF group in terms of symptoms, GERD-HRQL scores, manometric findings, and impedance-pH features. Dysphagia was not reported by the MNF group, while it was quite common (20% vs.0%, p = ns) in the NF group. Anti-reflux surgery was successful in all patients in the MNF group, whereas two patients in the NF group presented a slipped wrap and one recurrent reflux; two of these cases required redo-surgery (10% vs. 0%, p = ns). CONCLUSIONS: Our preliminary data demonstrated that the MNF is a safe and effective procedure. Further, it seems to reduce the failure rate associated to the surgical procedure.

Long-term health-related quality of life after minimally invasive surgery for diverticular disease.

BACKGROUND AND AIMS: The aim of this multicentric study was to evaluate the disease specific and the generic quality of life in patients affected by colonic diverticular disease (DD) who had undergone minimally invasive or open colonic resection or who had been treated with medical therapy in the long-term follow-up. PATIENTS AND METHODS: Seventy-one consecutive patients admitted to the departments of surgery of Padova and Arzignano Hospitals for DD were interviewed: 22 underwent minimally invasive colonic resection, 24 had open resection, and 25 had only medical therapy. The interview focused on disease specific and generic quality of life, body image, and disease activity. RESULTS: Padova Inflammatory Bowel Disease Quality of Life (PIBDQL) was validated for the use in DD patients. PIBDQL scores were significantly worse in all patients with DD than those obtained by healthy subjects and it correlated with the symptoms score. The generic quality of life seemed similar in patients who had minimally invasive colonic resection compared with healthy subjects. Body Image Questionnaire scores correlated inversely with the presence of a stoma. CONCLUSIONS: Disease activity resulted as the only independent predictor of the disease-specific quality of life. In fact, DD affected bowel function and quality of life of patients in the long-term follow-up regardless of the type of therapy adopted. The presence of a stoma affected the patients' body image.

Caustic ingestion and oesophageal cancer: intra- and peri-tumoral fibrosis is associated with a better prognosis.

OBJECTIVE: Oesophageal carcinoma is a well-known late complication of caustic ingestion, occurring in up to 7% of cases. We report a large series of patients with oesophageal scar cancer (SC), investigating the association between fibrosis and survival. METHODS: A total of 25 patients with a history of oesophageal SC (1979-2005) were retrospectively studied. The amount of intra- and peri-tumoral fibrotic tissue was measured with Azan-Mallory staining. A control group of patients with non-SC was used for comparison. RESULTS: Twenty-five patients (16 males:9 females, median age 59 years), presented with SC. The histotype was squamous cell carcinoma (SCC) in 20 (80%) patients, adenocarcinoma (AC) in three (12%) and verrucous carcinoma in two (8%). Oesophageal resection was performed in 17 of 25 (68%) patients; in eight (32%), only a palliative treatment (endoscopic/surgical) was possible. Mortality and morbidity rates were 4% and 40%, respectively. One-, 3- and 5-year overall actuarial survival rates for SC patients were 72%, 56% and 52%, respectively. The amount of fibrotic tissue around/within the tumour was significantly higher in SC patients (34.5% vs 5.9% non-SC, p=0.01); these patients had also a higher prevalence of tumours limited to the muscular wall (pT1-T2) (76% vs 28% non-SC, p<0.0001) and less lymph node metastases in T1-T2 cases (8% vs 34% non-SC, p=0.07). The 5-year survival was significantly better in SC patients: 71% versus 24% for resected cancers (p<0.0001), and 52% versus 15% for all observed patients (p=0.0001). CONCLUSIONS: The presence of fibrotic tissue around/within the tumour is associated with a better prognosis in SC. Fibrosis might offer a protection against both local spread and nodal dissemination.

Prediction of lymph node status in superficial esophageal carcinoma.

BACKGROUND: Esophageal carcinoma is among the cancers with the worst prognosis. Real chances for cure depend on both early recognition and early treatment. The ability to predict lymph node involvement allows early curative treatment with less invasive approaches. AIMS: To determine clinicohistopathological criteria correlated with lymph node involvement in patients with early esophageal cancer (T1) and to identify the best candidate patients for local endoscopic or less invasive surgical treatments. METHODS: A total of 98 patients with pT1 esophageal cancer [67 with squamous cell carcinomas (SCC) and 31 with adenocarcinomas (ADK)] underwent Ivor-Lewis or McKeown esophagectomy in the period between 1980 and 2006 at our institution. Based on the depth of invasion, lesions were classified as m1, m2, or m3 if mucosal, and sm1, sm2, or sm3 if submucosal. RESULTS: The rates of lymph node metastasis were 0% for the 27 mucosal carcinomas (T1m) and 28% for the 71 submucosal (T1sm) carcinomas (P < 0.001). Sm1 carcinomas were associated with a lower rate of lymph-node metastasis (8.3% versus 49 % sm2/3, P = 0.003). As for histotype, the rates of lymph node metastasis for sm1 were 0% for ADK and 12.5% for SCC; for sm2/3 there were no significant differences. On multivariate analysis, depth of infiltration, lymphocytic infiltrate, angiolymphatic and neural invasion were significantly associated with lymph node involvement. Neural invasion was the single parameter with the greatest accuracy (82%); depth of infiltration and angiolymphatic invasion had 75% accuracy. Altogether these three parameters had an accuracy of 97%. Five-year survival rate was 56.7% overall: 77.7% for T1m and 53.3% for T1sm (P = 0.048). CONCLUSIONS: The most important factors for predicting lymph node metastasis in early esophageal cancer are depth of tumor infiltration, angiolymphatic invasion, neural invasion and grade of lymphocytic infiltration. The best candidates for endoscopic therapy are tumors with high-grade lymphocytic infiltration, no angiolymphatic or neural invasion, mucosal infiltration or sm1 (only for ADK), and tumor <1 cm in size. For sm SCC and sm2/3 ADK the treatment of choice remains esophagectomy with standard lymphadenectomy.

Long-term outcome of operated and unoperated epiphrenic diverticula.

INTRODUCTION: The natural history of esophageal epiphrenic diverticula (ED) is not entirely clear; the decision whether to operate or not is often based on the personal preference of the physician and patient. The aim of this study was to evaluate the long-term fate of operated and unoperated patients with ED. MATERIALS AND METHODS: Clinical, radiological, and motility findings, and operative morbidity and long-term outcome of 41 patients with ED (January 1993 to December 2005) were analyzed. All patients were reviewed at the outpatient clinic or interviewed over the phone. A symptom score was calculated using a standard questionnaire and subjective patient assessment. The radiological maximum diameter of the ED was measured. RESULTS: Twenty-two patients (12M:10F; median age, 60 years) were operated. One underwent surgery for spontaneous rupture of a large diverticulum. Operative mortality was nil; postoperative morbidity was 22.7%, the most severe complication being suture leakage (4 patients, all managed conservatively); median follow-up was 53 months. Nineteen patients (9M, 10F; median age 70 years) were not operated: 3 received pneumatic dilations; median follow-up was 46 months. None of the patients in either group died for reasons related to their ED. Symptoms decreased in all operated patients and, to a lesser extent, also in unoperated patients. ED recurrence was observed in one operated patient. Four patients had GERD symptoms with esophagitis and/or positive pH-metry after surgery and 3 patients had persistent dysphagia/regurgitation and were dissatisfied with the outcome of surgery. DISCUSSION: Surgery is an effective treatment for ED, but carries a significant morbidity related mainly to suture leakage. Even in the long-term, unoperated patients do not die of their ED, though a better subjective symptom outcome is reported by operated patients. A non-interventional policy can safely be adopted in cases of small, mildly symptomatic ED.

Endoscopic ultrasound: accuracy in staging superficial carcinomas of the esophagus.

BACKGROUND: Endoscopic procedures may represent an alternative to esophagectomy for superficial neoplasms of the esophagus (T1m/T1sm), but they are considered curative only in case of no lymph node involvement. Endoscopic ultrasound (EUS) is the most accurate method to define both T and N staging of esophageal carcinoma. Aims of the study were to assess the staging accuracy of EUS in superficial lesions (T1m and T1sm) of patients who were candidates for esophagectomy or local endoscopic resection and to establish which variables (site of neoplasm, histologic type, macroscopic appearance) can affect the accuracy of EUS in distinguishing between T1m and T1sm lesions. METHODS: The study population consisted of 55 patients with superficial carcinoma of the esophagus who underwent EUS (October 2002 to January 2007). Endoscopic ultrasound features were compared with findings from surgical specimens or samples obtained at mucosectomy. RESULTS: There were 33 patients with adenocarcinoma (60%), which developed on Barrett's esophagus in 27 cases, 21 patients (38%) with squamous cell carcinoma, and 1 (2%) with lymphoepithelial-like carcinoma. All lesions were confirmed as T1 on pathology. Of the 22 (40%) T1m lesions on EUS, 19 (86%) were confirmed as T1m on pathology; of the 33 T1sm on EUS, 22 (66%) were confirmed as T1sm. Positive predictive value of EUS for invasion of the submucosa was 67%, negative predictive value 86%, sensitivity 88%, specificity 63%, and diagnostic accuracy 75%. The accuracy of EUS in evaluating lymph node metastases was 71%, with a negative predictive value of 84%. Endoscopic ultrasound accuracy in differentiating mucosal from submucosal lesions increased from the lower esophagus or gastroesophageal junction to the mid and upper esophagus (71%, 76%, and 100%, respectively; not significant). As for the histologic type, accuracy was 70% for adenocarcinoma and 81% for squamous cell carcinoma, (not significant); for lesions detected as type 0-IIa (13 patients), accuracy was 100%; for type 0-I lesions (23 patients), accuracy was 70% (p = 0.03). CONCLUSIONS: Despite difficulties in differentiating mucosal from submucosal lesions, even with 20-MHz miniprobes, EUS remains an extremely valuable tool when nonsurgical treatments are considered. Its staging accuracy depends on site and macroscopic appearance of the neoplasm.

Esophageal GIST: case report of surgical enucleation and update on current diagnostic and therapeutic options.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, but they have been rarely reported in the esophagus. The authors present the case of an esophageal GIST and discuss the diagnostic course and therapeutic options, as currently reported in the literature.

Effects of neoadjuvant therapy on perioperative morbidity in elderly patients undergoing esophagectomy for esophageal cancer.

BACKGROUND: The use of cytoreductive therapy followed by surgery is preferred by many centers dealing with locally advanced esophageal cancer. However, the potential for increase in mortality and morbidity rates has raised concerns on the use of chemoradiation therapy, especially in elderly patients. The aim of this study was to assess the effects of induction therapy on postoperative mortality and morbidity in elderly patients undergoing esophagectomy for locally advanced esophageal cancer at a single institution. METHODS: Postoperative mortality and morbidity of patients > or = 70 years old undergoing esophagectomy after neoadjuvant therapy, between January 1992 and October 2005 for cancer of the esophagus or esophagogastric junction, were compared with findings in younger patients also receiving preoperative cytoreductive treatments. RESULTS: 818 patients underwent esophagectomy during the study period. The study population included 238 patients < 70 years and 31 > or = 70 years old undergoing esophageal resection after neoadjuvant treatment. Despite a significant difference in comorbidities (pulmonary, cardiological and vascular), postoperative mortality and morbidity were similar irrespective of age. CONCLUSIONS: Elderly patients receiving neoadjuvant therapies for cancer of the esophagus or esophagogastric junction do not have a significantly increased prevalence of mortality and major postoperative complications, although cardiovascular complications are more likely to occur. Advanced age should no longer be considered a contraindication to preoperative chemoradiation therapy preceding esophageal resection in carefully selected fit patients.

[Diaphragmatic herniation after oesophagectomy: a report of two cases]. / Ernia transdiaframmatica dopo esofagectomia. Presentazione di 2 casi.

Diaphragmatic herniation is the protrusion of abdominal structures into the chest through a defect in the diaphragm. It is a rare complication following oesophagectomy. Preoperative diagnosis is important in order to establish both the nature and extent of the diaphragmatic defect. The treatment of choice is surgery. In a series of 574 intrathoracic oesophagogastroplasties performed at our Institution from 1990 to 2004, the prevalence of diaphragmatic herniation was 0.35%. We report two cases of major diaphragmatic herniation after oesophagectomy for cancer performed using a laparotomic-thoracotomic (case 1) and a laparoscopicthoracotomic approach (case 2). The case 1 patient was asymptomatic: hernia repair involved hiatoplasty and mesh positioning. The case 2 patient presented with vomiting and abdominal pain: she underwent emergency laparoscopic surgery and direct closure of the diaphragmatic tear. At 12 months' follow-up, both patients were symptom-free. A barium swallow confirmed that the previously herniated abdominal viscera had returned to the abdomen. Diaphragmatic herniation following oesophagectomy is a rare complication which may be asymptomatic or present as bowel obstruction. Several aetiopathogenetic factors may be responsible for diaphragmatic hernias: enlargement of the diaphragmatic hiatus, a combination of negative pressure in the chest and positive pressure in the abdomen, and small number of adhesions in the case of patients operated on with minimally invasive surgery. Surgical repair is the treatment of choice and is mandatory as emergency treatment in the case of symptomatic hernias.

Mediastinal carcinosis involving the esophagus in breast cancer: the "breast-esophagus" syndrome: report on 25 cases and guidelines for diagnosis and treatment.

INTRODUCTION: Breast metastases of mucosal/submucosal layers of the esophagus are extremely rare: esophageal involvement is usually part of a mediastinal carcinosis. AIM: We report the largest series to date of 25 cases of metastatic esophageal involvement from breast cancer, discussing both diagnostic techniques and treatment options. MATERIALS AND METHODS: Twenty-five female patients with a history of breast cancer referred for secondary esophageal involvement (1980-2006) were studied. RESULTS: All patients presented with worsening dysphagia. Twenty-four had undergone surgery for breast cancer a median of 10 years earlier: 1 had received chemoradiotherapy, and 17 had adjuvant radiotherapy/telecobalt therapy following breast surgery. Endoscopic biopsy/cytology were negative for cancer in 17 of 19 patients; in 9 patients, the diagnosis was made with thoracoscopy/laparoscopy. Immunohistochemical staining was done in 10 patients (ER and/or PrR positive). Fifteen patients presented with distant metastatic involvement. Therapy was directed toward dysphagia relief, mostly with endoscopic dilations/prostheses. Complications (4 perforations) occurred only in those 15 patients who had endoscopic dilations/prostheses. Fifteen patients had cytoreductive therapy. Nine of 25 patients are still alive. The median overall survival was 7 months; 1-, 3-, and 5-year survival rates were 44%, 16%, and 8%, respectively. CONCLUSIONS: A "breast-esophagus" syndrome can be defined: it is often diagnosed only after excluding other diseases or after relief of dysphagia with adequate therapy. The presence of distant metastases helps the diagnosis of esophageal involvement from mediastinal carcinosis, while diagnosis is a problem in case of mediastinal/pleural disease only: in this case, exploratory thoracoscopy is mandatory for a final diagnosis. Given the high related risk of perforation from endoscopic procedures (dilations/prostheses), the treatments of choice are currently hormone therapy or chemotherapy/radiotherapy.

Objective follow-up after laparoscopic repair of large type III hiatal hernia. Assessment of safety and durability.

BACKGROUND: Symptomatic results of laparoscopic repair of large type III hiatal hernias, with/without prosthetic mesh, are often excellent; however, a high recurrence rate is detected when objective radiological/endoscopic follow-up is performed. The use of mesh may reduce the incidence of postoperative hernia recurrence or wrap migration in the chest. METHODS: We retrospectively studied 54 patients (10 men, 44 women; median: age 64.5 years) with a diagnosis of large type III hiatal hernia (>1/3 stomach in the chest on x-ray) who underwent laparoscopic repair at our department from January 1992 to June 2005. Complications, recurrences, and symptomatic and objective (radiological/endoscopic) long-term outcome were evaluated. RESULTS: Nineteen patients had laparoscopic Nissen/Toupet fundoplication with simple suture; in 35 patients a double mesh was added. The median radiological/endoscopic follow-up was 64 months (interquartile range (IQR): 6-104) for the non-mesh group and 33 (IQR:12-61) for the mesh group (p = 0.26). Recurrences occurred in 11/54 (20%) patients: 8/19 (42.1%) without mesh and 3/35 (8.6%) with mesh (p = 0.01). The 3 recurrences in the mesh group all occurred < or =12 months postoperatively; 4/8 recurrences in the non-mesh group occurred > or =5 years after operation. On multivariate logistic regression analysis, only mesh absence significantly predicted hernia recurrence or wrap migration. DISCUSSION: Laparoscopic repair of large type III hiatal hernias is safe and effective. Short-term symptomatic results are excellent, but mid-term objective radiological/endoscopic evaluation reveals a high recurrence rate. Possible reasons for failure of a laparoscopic hiatal repair are tension or poor muscle tissue characteristics in the hiatus. The use of a mesh, either by reducing tension or reinforcing muscle at the hiatus, might be associated with a lower recurrence rate. Longer-term follow-up will be needed before definitive conclusions can be drawn, however.

Long-term results (6-10 years) of laparoscopic fundoplication.

Most papers report excellent results of laparoscopic fundoplication but with relatively short follow-up. Only few studies have a follow-up longer than 5 years. We prospectively collected data of 399 consecutive patients with gastroesophageal reflux disease (GERD) or large paraesophageal/mixed hiatal hernia who underwent laparoscopic fundoplication between January 1992 and June 2005. Preoperative workup included symptoms questionnaire, videoesophagogram, upper endoscopy, manometry, and pH-metry. Postoperative clinical/functional studies were performed at 1, 6, 12 months, and thereafter every other year. Patients were divided into four groups: GERD with nonerosive esophagitis, erosive esophagitis, Barrett's esophagus, and large paraesophageal/mixed hiatal hernia. Surgical failures were considered as follows: (1) recurrence of GERD symptoms or abnormal 24-h pH monitoring; (2) recurrence of endoscopic esophagitis; (3) recurrence of hiatal hernia/slipped fundoplication on endoscopy/barium swallow; (4) postoperative onset of dysphagia; (5) postoperative onset of gas bloating. One hundred and forty-five patients (87 M:58 F) were operated between January 1992 and June 1999: 80 nonerosive esophagitis, 29 erosive esophagitis, 17 Barrett's esophagus, and 19 large paraesophageal/mixed hiatal hernias. At a median follow-up of 97 months, the success rate was 74% for surgery only and 86% for primary surgery and 'complementary' treatments (21 patients: 13 redo surgery and eight endoscopic dilations). Dysphagia and recurrence of reflux were the most frequent causes of failure for nonerosive esophagitis patients; recurrence of hernia was prevalent among patients with large paraesophageal/mixed hiatal hernia. Gas bloating (causing failure) was reported by nonerosive esophagitis patients only. At last follow-up, 115 patients were off 'proton-pump inhibitors'; 30 were still on medications (eight for causes unrelated to GERD). Conclusion confirms that laparoscopic fundoplication provides effective, long-term treatment of gastroesophageal reflux disease. Hernia recurrence and dysphagia are its weak points.

Results of esophagectomy for esophageal cancer in elderly patients: age has little influence on outcome and survival.

OBJECTIVE: The aging of the population and a longer life expectancy have led to an increased number of elderly patients with esophageal cancer being referred for surgical treatment. The aim of this study was to assess the effects of age on the outcome of surgery for esophageal cancer at a single institution. METHODS: Perioperative outcome and long-term survival of patients at least 70 years old undergoing esophagectomy between 1992 and 2005 for cancer of the esophagus or esophagogastric junction were compared with findings in younger patients. Patients who underwent an abdominal procedure only were excluded from the analysis. RESULTS: The analysis considered 580 patients younger than 70 years and 159 at least 70 years old. Clinical presentation in the two groups was similar, as were postoperative morbidity and mortality, despite significant differences in perioperative risk factors. Irrespective of age, overall survival was 34% at 5 years for all patients and 37% for patients with R0 resection. CONCLUSIONS: Increased experience and refinements in perioperative care explain the better results of esophagectomy in elderly patients in recent years. Short- and long-term outcomes after esophagectomy for carcinoma in patients older than 70 years are comparable with those of their younger counterparts. Advanced age per se thus should not be considered a contraindication to esophageal resection.

Erosion of an esophageal endoprosthesis into the trachea.

Acquired benign non-neoplastic tracheoesophageal fistulas are unusual, demanding clinical entities. Surgical technique and final outcome depends on fistula size. A one-stage procedure with esophageal resection is preferred when the fistula is located in the upper third of the trachea and is less than 1 cm long.
