Potential impact of EUS-FNA staging of proximal lymph nodes in patients with distal esophageal carcinoma.

BACKGROUND AND STUDY AIMS: Distal esophageal carcinomas can be resected using transthoracic esophagectomy or transhiatal esophagectomy. Accurate diagnosis of subcarinal and supracarinal lymph-node metastases is important for selecting the surgical strategy. The impact of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) on the preoperative diagnosis of subcarinal and supracarinal lymph-node metastases in patients with distal esophageal carcinoma was therefore investigated. PATIENTS AND METHODS: Patients with a resectable distal esophageal carcinoma and subcarinal and/or supracarinal lymph nodes visualized on preoperative EUS were prospectively included. The lymph nodes were sampled using EUS-FNA, and if they were found to have metastases, transthoracic resection was offered; by contrast, patients without metastases were offered a transhiatal resection. RESULTS: Lymph-node metastases were found with EUS-FNA in 11 of the 48 patients included (23 %). Thirteen patients had suspicious nodes on EUS, in four of whom (31 %) the diagnosis was changed into nonmalignant nodes with FNA. Thirty-five patients had nonsuspicious nodes on EUS, in three of whom (9 %) the FNA procedure revealed malignant cells. CONCLUSIONS: EUS with the addition of the FNA procedure has a significant impact on decision-making in patients with esophageal carcinoma in whom transhiatal esophagectomy would otherwise be planned.

[The para-esophageal hernia: a rare hiatal hernia requiring a specific approach].

In three patients, a woman aged 87 years who presented with signs indicating a myocardial infarction, a man aged 31 suffering from postprandial epigastric pain that suddenly worsened, and a woman aged 60 years with longstanding postprandial pain and recent fatigue due to anaemia, a para-oesophageal hernia was diagnosed. Para-oesophageal herniation is an uncommon disorder accounting for approximately 5% of all hernias at the oesophageal hiatus. They are distinguished from the more common sliding hiatal hernia by a relative preservation of the intra-abdominal fixation of the gastro-oesophageal junction. These patients show that the clinical presentation of para-oesophageal rolling hernias is different from that of sliding hernias. Pathological reflux may occur; though symptoms associated with a relative obstruction of the stomach within the hernia sac, such as dysphagia, are more common. Rare non-specific symptoms such as anaemia and loss of weight are also seen. Adequate therapy differs from that of a sliding hernia and should be individualized: surgical correction is indicated in a healthy patient with a symptomatic para-oesophageal hernia, such as in the last patient. However, when the hernia is incidentally diagnosed or when comorbidity is present, such as in the first patient, a wait-and-see policy is recommended. Only in case of a threatening incarceration, such as in the second patient, is an emergency operation indicated.

[The mammary duct fistula: a persistent problem that can be treated adequately].

Three female patients, 39, 39 and 46 years old, had recurrent, non-puerperal, subareolar abscesses caused by obstructed and dilated lactiferous ducts and resulting in paramamillary fistulas. Further recurrence was stopped by surgery. Based on the pathogenesis, surgery is the recommended treatment for this chronic ailment, i.e. fistulectomy using a radial incision through the centre of the nipple and excising the pathological nipple-areolar complex. Only the nipple is reconstructed, leaving the remainder of the wound open for healing by secondary intention and thus preventing recurrence.

Outcome of patients with esophageal carcinoma and suspicious celiac lymph nodes as determined by endoscopic ultrasonography.

BACKGROUND AND STUDY AIMS: The management of patients with esophageal cancer with malignant celiac lymph nodes (CLNs) is controversial. In this study we evaluated the management and survival of patients with positive CLN findings on endoscopic ultrasonography (EUS) and compared the outcome in surgically treated patients with that of nonsurgically treated patients. PATIENTS AND METHODS: The EUS database of the Academic Medical Center was retrospectively searched for patients with esophageal carcinoma and EUS-positive CLN. Follow-up comprised the review of medical charts and contact with general practitioners. RESULTS: From 1993 through 2000, 78 patients with esophageal carcinoma and suspicious CLN were eligible for inclusion in this study. The median survival of patients with CLN size < 2 cm was 13.5 months vs. 7.0 months for patients with CLN size >2 cm ( P = 0.01). In a multivariate model, CLN size was the only predictive factor for poor patient survival. Of the 78 study patients, 13 underwent a surgical resection and 65 received nonsurgical treatment. The surgical group was significantly younger and all patients in this group had CLN size < 2 cm. The median survival for the surgical group was 13.7 months vs. 13.5 months for the nonsurgical group with CLN size < 2 cm ( P = 0.63). CONCLUSIONS: In this retrospective study, CLN size was a significant predictor for poor survival. The surgically treated patients had a medium-term survival similar to that of nonsurgically treated patients with a CLN size < 2 cm. These findings underline the prognostic value of CLN size in patients with esophageal carcinoma.

[Barrett's esophagus: endoscopic treatment of high-grade dysplasia and early cancer].

In a Barrett's oesophagus without dysplasia, endoscopic control every 3-5 years is sufficient. If low-grade dysplasia is encountered in the surveillance biopsies, then endoscopy should be repeated within 3-6 months and yearly thereafter if the low-grade dysplasia persists. Antacid medication must be prescribed in cases with extensive inflammation. The endoscopic treatment of patients with high-grade dysplasia and/or early cancer of the mucosa in a Barrett's oesophagus (tissue ablation and/or mucosa resection) seems a promising alternative to surgery in view of the combination of effectiveness, limited invasiveness compared to surgical resection, and the preservation of a functional oesophagus. Data from long-term follow-up are still limited. Strict endoscopic surveillance will probably detect metachronic abnormalities in an early and still curable stage, creating a new opportunity for endoscopic treatment.

[Cyclooxygenase(COX)-2-inhibition in the prevention and treatment of colorectal carcinoma].

Epidemiological studies have found that long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with a lower risk of colorectal cancer (CRC). Cyclooxygenase (COX)-2 expression is present in colorectal cancer and overexpression is associated with metastases and poorer prognosis in multivariate analysis. NSAID treatment results in a reduction of the incidence of colorectal adenoma in patients with familial adenomatous polyposis, in patients with a history of colorectal adenomas and in patients with a history of CRC. Pre-clinical research shows that COX-2 expression is associated with cell proliferation, angiogenesis, apoptosis inhibition and local immune-down modulation. An anticarcinogenic effect has been shown specifically in selective COX-2 inhibitors in animal models. Selective COX-2 inhibitors have fewer adverse effects than the non-selective NSAIDs and are promising chemopreventative and chemotherapeutical agents. The effects of selective COX-2 inhibition in the prevention of and treatment for colorectal carcinoma will be investigated in clinical randomized multicentre trials.

[Primary adenocarcinoma of the small intestine].

Three patients, a woman aged 46 years and two men aged 81 and 62 years, presented with abdominal pain, nausea, vomiting and/or weight loss. A small intestine follow-through series revealed a significant stenosis in all 3 patients. A laparotomic partial resection of the affected jejunum and corresponding mesentery was performed. A primary adenocarcinoma of the small intestine was diagnosed; pathology revealed that the resections were radical, and pT3N0, pT2N0 and pT3N0 stage tumours respectively. The first patient underwent a repeat operation four months later due to similar complaints caused by a tumour recurrence; fifteen months later she died from recurrent disease. The second patient was disease-free 3 years after surgery. In the third patient, liver and peritoneal metastases developed 16 months after surgery; he died 10 months after palliative chemotherapy had been initiated. Adenocarcinoma of the small intestine is a rare disease and patients often present late with aspecific complaints. This, combined with the fact that these tumours tend to follow an aggressive course, results in a poor five-year survival rate of 10-35%. Surgery is the only curative treatment currently available. A greater awareness of this type of tumour is needed for treatment results to improve.

[Transhiatal or transthoracic resection of esophageal carcinoma based on tumor location, positive high-thoracic lymph nodes and preoperative physical condition].

The limited transhiatal resection for the surgical treatment of oesophageal cancer is aimed at limiting early postoperative complications by not performing lateral thoracotomy and formal lymphadenectomy. The extended transthoracic approach with two-field lymphnode dissection is intended to improve long-term survival. The recurrence pattern after transhiatal resection suggests that a subgroup of patients might benefit from the more extended approach. In a large randomized trial in two high-volume Dutch academic hospitals, extended resection resulted in more postoperative (pulmonary) complications and a prolonged postoperative recovery time, but when compared to transhiatal resection, had only a limited impact on quality of life. The estimated 5-year survival advantage after extended resection was 10% (95% confidence interval: -3% to +23%). Subgroup analysis indicated a 17% 5-year survival advantage for patients with oesophageal cancer, but only a 1% advantage for patients with cancer of the cardia or gastro-oesophageal junction. The individualized operative approach for patients with potentially curable oesophageal cancer is based on tumour location, positive high-thoracic lymph nodes and preoperative physical condition.

Routine morphometrical analysis can improve reproducibility of dysplasia grade in Barrett's oesophagus surveillance biopsies.

BACKGROUND: The grade of dysplasia found in Barrett's oesophagus surveillance biopsies is a major factor to determine follow up and treatment. However, it has been reported that the reproducibility of the grading system is not optimal. AIMS: To compare routine and expert dysplasia grades in Barrett's oesophagus surveillance biopsies. To evaluate prospectively morphometrical grading support and to assess the pitfalls in its daily application. METHODS: Consecutive biopsies (n = 143) were graded routinely by experienced general surgical pathologists as no dysplasia (ND), indefinite for dysplasia, low grade dysplasia (LGD), and high grade dysplasia (HGD). Two expert gastrointestinal pathologists blindly reviewed all sections. The stratification index of nuclei, mean nuclear area, and Ki67area% were assessed routinely according to a strict protocol. With these features, the previously described morphometrical grade was calculated for each case. The grades provided by the experts, surgical pathologists, and morphometry were compared. RESULTS: The general pathologists graded many more cases as dysplastic than did the experts. Complete agreement between the experts' grades and the original grades was 50 of 143 (35%). Sixty four of the 71 original LGDs and 11 of the 23 original HGDs were downgraded by the experts, whereas one LGD was upgraded. In 93 of the 143 biopsies, at review pitfalls or special characteristics of a technical nature (tangential cutting, severe inflammation, ulcer or the squamocylindrical junction very close by, among others) were seen in the part of the biopsy marked as diagnostic. These probably contributed in part to the original overdiagnoses and could have been prevented or corrected. The morphometrical grading model has not been developed to compensate for this; application of the current morphometrical grading method is not allowed and may result in erroneous (usually too high) morphometrical grades. In spite of this, all HGDs according to the experts were recognised as such by morphometry, also in these technically less adequate sections or areas. However, 46% of the experts' downgrades occurred in technically adequate sections and thus were caused by a difference in interpretation. Here, morphometrical support proved to be useful because, in agreement with the experts, it downgraded 51% of the original LGDs, upgraded one of eight NDs to LGD and one of 39 LGDs to HGD. CONCLUSIONS: Experts downgraded a high proportion of biopsies graded as LGDs and HGDs by the surgical pathologists. Morphometrical grading can be used for daily quality control; the results were close to those of the experts and corrected a large number of cases erroneously graded by surgical pathologists.

[Consequences of caustic damage of the esophagus].

Following ingestion of a highly concentrated acetic acid solution, three women aged 29, 23 and 25 years old, suffered damage to the oesophagus and the stomach, respiratory and renal insufficiency and haemolysis. After intensive treatment, gastric tube reconstruction was carried out in 2 of these patients, and the third woman required repeated dilatations of the oesophageal stricture from 6 weeks after ingestion onwards. This resulted in a normal passage of solid food in all women. A 58-year-old man who had ingested caustic soda at 4 years of age, presented with increasing problems associated with swallowing food. A squamous cell carcinoma was diagnosed and treated with chemotherapy, oesophagus-cardia resection and gastric tube reconstruction. After 2 years the tumour has not recurred. Ingestion of corrosive substances can lead to serious damage of the gastrointestinal tract. Early endoscopy is important in establishing the extent of the injury. During the acute phase, intensive care admittance is often necessary and resection of the oesophagus is also necessary in some cases. Subsequent treatment can vary from endoscopic dilations to gastric tube reconstruction following resection of the oesophagus.

Hospital volume and hospital mortality for esophagectomy.

BACKGROUND: Hospital mortality after esophagectomy has decreased from 29% to 7.5% over the last decades because of improved surgical techniques and better perioperative care. Suggestions have been made that a further decrease in hospital mortality may be achieved by centralization of esophagectomies in high volume centers. METHODS: The effect of hospital volume on hospital mortality after esophagectomy in the Netherlands was analyzed based on data from the Dutch National Medical Registry and the Dutch Network and National Database for Pathology over the period 1993-1998. RESULTS: Annually, approximately 310 (range, 264-321) esophagectomies are performed in the Netherlands. Fifty-two percent are performed in 43-55 low volume centers (1-10 resections a year). Six percent are performed in 1-3 medium volume centers (11-20 resections a year). The remainder (42%) is performed in two high volume centers (> 50 resections a year). Hospital mortality is 12.1%, 7.5% and 4.9% respectively (P < 0.001). The high volume centers seem to see slightly more advanced tumors than the low and medium volume centers. CONCLUSIONS: There is a significant (inverse) relation between hospital mortality and hospital volume for esophageal resection in the Netherlands. Although hospital mortality is not the only measure for quality of care, these data suggest a potential beneficial effect to centralization of esophagectomy in the Netherlands.

[Mix-up of patient specimen: DNA-microsatellite analysis as a fast identification method].

In a man aged 56 years with dysphagia, an oesophageal biopsy was found to contain an adenocarcinoma. In view of the discrepancy between the clinical and the histological pictures, the biopsy was repeated; in a second biopsy no carcinoma was demonstrable. DNA microsatellite analysis proved that the first biopsy originated from another person. The scheduled oesophageal resection was cancelled and the patient was reassured. A woman aged 77 years underwent gastrectomy because of biopsy samples with adenocarcinoma. However, no tumour was found in the resected stomach. DNA microsatellite analysis showed that the biopsy samples indeed originated from the patient. Unfortunately, mix-up of patient specimens occasionally occurs. Especially a discrepancy between the clinical picture and the histological diagnosis must raise the suspicion of a specimen mix-up. In such cases, DNA microsatellite analysis can give a rapid and reliable answer whether a mix-up has indeed taken place.

Transthoracic versus transhiatal resection for carcinoma of the esophagus: a meta-analysis.

There is much controversy about the surgical approach to esophageal carcinoma: should an extensive resection be done to optimize long-term survival or should the extent of the operation be limited to obtain lower perioperative morbidity and mortality rates? We systematically reviewed the English-language literature published during the past decade, with emphasis on the differences between transthoracic and transhiatal resections regarding early morbidity, in-hospital mortality rates, and 3- and 5-year survival. Although transthoracic resections had significantly higher early (pulmonary) morbidity and mortality rates, 5-year survival was approximately 20% after both transthoracic and transhiatal resections.

Benign tracheo-neo-esophageal fistulas after subtotal esophagectomy.

BACKGROUND: Benign tracheo-neo-esophageal fistulas after esophagectomy are rare and treatment can be challenging. They can result from perioperative tracheal injury or various postoperative complications. METHODS: Charts of 6 patients with a benign tracheoneo-esophageal fistula after subtotal esophagectomy treated in this institution between July 1993 and August 1999 were analyzed. RESULTS: Three men and 3 women (median age 61 years) developed a fistula after subtotal esophagectomy. Symptoms varied from mild swallowing difficulties to aspiration pneumonia and mediastinitis. Two patients with mild symptoms were treated conservatively. In 1 patient a long fistula was partly excised through the neck. In 3 patients the gastric tube was excluded or excised, with surgical closure of the tracheal defect. The alimentary tract was reconstructed by colonic interposition. There were no major complications. After a median follow-up of 1.6 years, all fistulas were closed. All patients were capable of sufficient oral intake. CONCLUSIONS: A benign tracheo-neo-esophageal fistula after esophagectomy is a rare, but serious complication. Site and size of the fistula, together with the severity of symptoms, should dictate management.
