[Current diagnosis of gastroesophageal reflux disease: learning experience].

The authors report their study on gastro-esophageal reflux disease, a pathology that has become increasingly common over the past years reflecting both a real increase and the use of new and more sophisticated and reliable diagnostic methods and tests. It can be included in the group of pathologies absorbing the largest proportion of financial resources, even exceeding biliary lithiasic disease according to American studies. The authors start by analysing the symptoms of gastroesophageal reflux disease, drawing a distinction between typical (heartburn, epigastric pain and postprandial regurgitation) and atypical symptoms (laryngotracheal symptoms, bronchopulmonary symptoms and esophageal motor incoordination). They outline the diagnostic iter and tests most widely used today to achieve a correct diagnosis. Lastly, they report their experience of 160 patients attending their esophageal diagnostic unit since January 1999 who underwent a number of different instrumental tests, the results of which are compared. Three different aspects are compared: the presence of symptoms, 24-hour pH-metry and endoscopic tests. All these are necessary for a correct diagnosis of gastroesophageal reflux disease and to evaluate the possibility and efficacy of surgery. They emphasise the diagnostic importance of 24-hour pH-measurement as the only test that can directly reveal gastroesophageal reflux. Positive pH results represent a discriminating element in deciding whether the patient should undergo surgery.

[Gastroduodenal reflux after laparotomic or laparoscopic cholecystectomy].

BACKGROUND: The authors analyse gastroduodenal reflux (GDR) in the light of the progress made over the past ten years. The good results achieved using mini-invasive techniques in cholecystectomy prompted the authors to compare laparotomic and laparoscopic cholecystectomy in order to evaluate the influence of both techniques in determining GDR and clinical symptoms. METHODS: Symptoms were evaluated before and after surgery in 30 patients operated using a laparotomic technique and in 30 patients operated using a laparoscopic technique. Two groups of 10 patients, operated respectively using laparotomic and laparoscopic techniques, were studied both clinically and endoscopically before and after surgery. RESULTS: The analysis of the results shows a lower incidence of GDR and typical symptoms of GDR in patients undergoing laparoscopic surgery. The rationale underlying the lower incidence of GDR and its symptoms in these patients compared to the more conventional group is not completely clear. CONCLUSIONS: These results may be influenced by reduced surgical trauma and the careful selection of case or the laparoscopic technique, hence the exclusion of cases complicated by severe cholecystitis.

[Duodeno-gastric reflux in gallbladder stones and after laparotomic cholecystectomy].

BACKGROUND: Duodeno gastric reflux (DGR) is still a not well-defined condition, even though it has been the subject of different studies for many years. METHODS: The authors examine its relation with gallstones before and after the surgical removal of the gallbladder. After examining various study techniques, they present their experience of DRG. In this work the methodology used in a group of 40 patients suffering from gallstones and operated by laparotomic cholecystectomy is presented. All patients have been subjected to a clinical questionnaire in order to evaluate their symptoms, before and after cholecystectomy, and at the same time they have been subjected to an endoscopic exam. It s not easy to comment the RESULTS. RESULTS: Actually, of 32 patients (80%) showing DGR symptoms before surgical treatment, 20 showed their persistence, worsening, or the appearance of new symptoms after cholecystectomy, while 12 were completely asymptomatic. Of 8 patients with no symptoms before cholecystectomy, 3 developed a typical DGR symptomatology while 5 were asymptomatic. CONCLUSIONS: So 57% of patients were DGR symptomatic after surgical treatment. The compromised function of cholecystitis with calculi, antrum-pyloric-duodenal motility, continuous bile flux in the duodenum, surgical trauma all interact in determining DGR.

[Simultaneous bilateral pneumothorax. Case report].

A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available.

[Lung surgery in the elderly].

Lung surgery in the elderly, once considered a major risk, to be avoided if possible has become more popular in recent years as a result of many factors. First: lung cancer incidence has increased significantly in every age group but mostly in the elderly. Second: diagnosis at an early stage of the disease is higher in patients over 70 due to more frequent medical control in old subjects. Third: we now have more and more humans over 80 and a life expectancy increasing over the years. Fourth: preoperative, operative and postoperative medical supports are now safer and more reliable than previously. Operability criteria in the elderly are substantially the same as in younger group of patients for lung cancer. There are no reasons to refuse surgery in a subject over 80 because he is old. Lobectomy is the procedure of choice for lung cancer even in the elderly. Pneumonectomy must be avoided preferring a less radical procedure (wedge resection) so avoiding the risk of a postoperative respiratory failure that is often fatal for a patient with in border line functional respiratory tests, as often happens in the elderly. Thoracoscopic atypical resections must be considered in patients when a wedge resection is indicated preoperatively and almost always metastatic pulmonary lesion.

Lymph node dissection in surgical treatment of esophageal neoplasms.

BACKGROUND: Until now therapy of carcinoma of the esophagus has presented an aura of pessimism, resulting in an attitude among physicians that cure was impossible. Presently the overall 5-year survival is between 38.3% and 55% thanks to new radical surgical techniques. The aim of this work is to evaluate lymph node dissection in treatment of esophageal carcinoma by analyzing morbidity, mortality, survival and quality of life. METHODS: From 1975 to 1995, 170 patients with carcinoma of the esophagus and cardia underwent operation, of whom 165 underwent 2-field lymphadenectomy and four 3-field lymphadenectomy; one patient was submitted to self-transplanting jejunal loop to neck. One hundred and twenty-two patients had standard resection and 47 en bloc resection. RESULTS: Lymph node involvement is often found in patients with superficial carcinoma and it greatly influences outcome after esophagectomy. In 2-field lymphadenectomy morbidity and mortality are more frequent in en bloc resections; global 3-year survival was better in patients with early lesions. Three-field lymphadenectomy was performed in only few cases, not sufficient to express a definitive opinion. CONCLUSIONS: On the basis of our experience, we conclude that the better survival is particularly dependent on early diagnosis, histological type of neoplasia and following surgical treatment, especially on the type of resection with 2 or 3-field lymphadenectomy.

[Surgery of large ventral hernias. Personal experience in 1990-1997].

BACKGROUND: The surgical treatment of large wall defects conventionally defined as an extension over 10 cm is discussed. The difficulty to contain the bowels that have lost law of domicile in the abdominal hollow, constitutes motive for notable increase of the endo-abdominal Pressure with serious consequences in the postoperative course and this leads to the use of prothesis meshes that allow the closing of the abdominal hollow with the Tension-Free technique. METHODS: Personal experience embraces 45 patients, with large wall defects, divided into 21 patients with overumbilical location, 14 with umbilical location, 10 with periumbelical location; a simple suture has been used in 7 cases, the reconstruction of the wall according to Stoppa in 36 cases and the apposition of Goretex net internally and Marlex net externally in 2 cases. RESULTS: There have been neither mortality, neither recidivists of illness, but only some complications: 9 cases of superficial infection, 1 case of intestinal occlusion and 2 of subcutaneous seroma. CONCLUSIONS: According to their experience and wide literature review, the authors draw some conclusions: an accurate toilet and a careful evaluation of the respiratory functionality are fundamental; it's necessary to postpone surgical intervention in presence of local inflammation and, where this is improrogable it's opportune to avoid the use of prothesis meshes or refold on readsorbible prothesis; special care must be taken to the hemostasis and an aspirative drain for 24-48 hrs preserves from the risk of postoperative hematomas and following local infections. The submuscular mesh permits a Tension-Free suture and for this reason it would have nowdays a more extensive use. Finally it's pointed out the choice of a PTFEe mesh in contact with the intestinal skein.

[Essential varicocele. Which treatment?].

Purpose of the paper is to sum up the problem of surgery of idiopathic varicocele according to the present possibilities, both surgical and sclerotic. A wide review of the literature underlines a high rate of relapses and persistence of the disease (with a percentage from 10 to and 10%) following the two most used technique: retrograde sclerotic therapy under radioscopic control and surgical retroperitoneal or inguinal ligature of the internal spermatic vein; this technique was preferred by us until 1997. The percentage of failures, high with reference to the benign form of the disease (over 10% in our series of more than 100 patients submitted to clinical and flow-meter examinations) let the authors suggest a combined and simultaneous operation of ligature both internal and external of the spermatic vein at the level of the internal inguinal ring. Anatomical reasons confirm the opportunity of this procedure since the involvement of the system of the external spermatic vein is present in about the 20% of the cases of idiopathic varicocele in accordance with various flebografic studies. The possibility of escape through the external spermatic vein is eliminated in the case in which such vessel is preserved, and it seems frequent above all in 3rd degree idiopathic varicocele where many anastomotic vessels between the two systems are present. This procedure can be made both in general or local anaesthesia, it doesn't involve postoperative hospital stay and present the same acceptable postoperative complication of other proposed operations. The laparoscopic treatment even if easily performed at the level of the internal inguinal ring, doesn't seem justified for the higher cost and equal compliance for the patient. Besides, it is not possible to proceed laparoscopically under local anaesthesia.

[Secondary costal myxoid chondrosarcoma. Presentation of a clinical case].

A type of malignant neoplasm of not frequent observation is reported and the difficulties concerning the distinction from the benign counterpart are underlined, for which a detailed instrumental study is made necessary, integrated with pre and, above all, postoperative histologic analysis. A white male patient of 83, affected by plurirecidivant chondromyxoma of the rib, was admitted for local recurrence. The lesion objectively appeared not dissimilar from the preceding ones, as an ovalar mass fixed on the underlying plains. Radiologic and ultrasonographic examinations seemed to confirm the admission diagnosis; at the end the patient underwent a new intervention. Histologic examination of the lesion yielded a diagnosis of chondromyxosarcoma. The clinical case is made even more interesting by the finding, through the TC technique, preoperatively performed, of a metastatic repetition on the opposite side. The authors examine the problem of the early recognition of a malignant neoplasm developing, in a patient with a clinical history of recidival chondromyxoma. Physical examination and laboratory analysis are not useful in the assessment of the occurring transformation. At molecular level chondromyxosarcoma is characterized by several genomic rearrangements and mutations. Though primitive chondromyxosarcoma often involves the ribs, chondromyxoma's transformation into its malignant counterpart is not a common event. The development of distant metastasis characterizes long term cases. Given the lack of encouraging results about chemo and radio-therapy efficacy in influencing the natural course of the disease, a systematic approach will be made necessary in patient management.

[Surgery of dysphagic diseases. Personal experience (349 surgical interventions)].

The authors report their surgical experience relating to dysphagic diseases of the esophagus (349 cases). In the light of these results, they describe the different surgical techniques used in the various pathologies: 1) Esophageal diverticula: The value of a careful evaluation of subdiverticular spasm is emphasised using preoperative manometry in cervical and epiphrenic diverticula, leading to subdiverticular myotomy when present. 2) esophageal achalasia and intermediate motor disorder: A clear difference must be drawn between these two diseases owing to the different motor behaviour of the esophagus. Dilatation of the LES is only useful in intermediate motor disorder and should be avoided in esophageal achalasia where a gastroesophageal reflux is produced if dilatation fails. Intraoperative manometry is very useful during the extramucosa myotomy phases as an indication of the complete removal of the sphincteric barrier, thus avoiding the risk of persisting disease. 3) Non-neoplastic stenosis. In primary stenosis (caused by caustic agents, primary GER or associated with JE) a conservative approach is advisable, whereas in iatrogenic stenosis (mainly linked to dilatation or cardiac surgery), owing to the anatomic complexity of the esophagogastric junction, a more radical approach is often required in the form of esophagogastric resection or even sub-total esophagectomy. 4) Neoplastic stenosis: Leiomyomas, although unusual, represent a clear indication for thoracoscopic access, provided that the dimensions allow it. Esophageal cancers represent a major surgical problem. A radical approach is represented by TE and the subsequent use of the stomach, or more rarely, the colon to reconstruct the alimentary tract. In spite of the very low resectability rate owing to locoregional spreading, until recently palliative surgery was essential to allow patients to eat. The introduction of autoexpanding prostheses, positioned using endoscopic methods, has provided a better solution to this problem.

[Dilatation versus surgery in the treatment of cardial achalasia].

Both surgery and dilatation are useful for the treatment of cardial achalasia. The authors make a wide review of the literature with particular attention to reports comparing results of these procedures. This review evidences that surgery gives better results than dilatations (84.4% of good results with surgery against 71.4% with repeated dilatations) and is certainly more stable over the years. Mini-invasive surgery points out even more strongly that surgery is nowadays to be preferred. Laparoscopy makes it possible to avoid postoperative pain, to discharge the patient in a couple of days and finally to eliminate surgical scars. Complications, even more frequent after surgery (5.5% against 2.1% of dilatation) are still acceptable in number and not heavy in quality.

[Prosthetic materials in surgery of esophageal cancer. Personal experience].

Even if the incidence of esophageal carcinoma is low (25% in comparison to rectal cancer) the total mortality of this disease is very high (superior to rectal cancer itself according to Am.Ca.SO. data). That's because of the high number of non resectable patients when they are first seen by the physician for dysphagia. The aim of the treatment in such cases is to permit a sufficiently good intake to the patient avoiding non-acceptable gastrostomy. The authors report their experience using esophageal prosthesis (27 cases). Mortality rate was 3.7% distal migration 7.4%. They report 3 cases of "minor" complication (11.1%). The mean survival was 5.3 months, the quality of life was satisfactory in all treated cases.

[Esophago-jejuno-gastroplasty in the treatment of peptic stenosis of the esophagus].

From 1973 to 1994, 21 patients with esophageal peptic stenosis were submitted to esophago-jejuno-gastroplasty with Merendino's technique. In 14 cases peptic stenosis developed after Heller's myotomy for achalasia, associated in 3 cases with fundoplication. In 3 patients the stenosis was secondary to fundoplication. Other 3 subjects presented a primary stenosis. One patient showed Barrett's esophagus with in situ carcinoma. Endoscopic esophageal dilatation was attempted in every patient with no satisfactory results. One patient died for a postoperative cardiopulmonary failure (4.7%). One patient developed a fistula of the esophago-jejunal anastomosis treated with enteral nutrition successfully (4.7%). In another subject splenectomy was performed following a iatrogenic injury (4.7%). Minor complications developed in 5 patients (23.7%). After one year from operation in 1 patient a severe stricture of esophago-jejunal anastomosis appeared; it was treated with anastomotic resection and reconstruction. After 8 years one patient was submitted to a partial resection of interposed jejunal loop, that was redundant. In 18 patients long term follow-up showed good results in 14 patients (78%), discrete in 2 (11%), unsatisfactory in 2 (11%). Our results show that Merendino's esophago-jejunal gastroplasty allows to achieve good results with acceptable rate of mortality and morbidity.

[Dysphagia associated with aorto-cardiac compression on the distal esophagus: a rare event but not exceptional in the elderly].

Among the pathologies responsible for dysphagia in the elderly, the aortic compression on the distal oesophagus awakens a certain clinical interest. Cipho-lordosis, which is often present in aged females, worsens the effects of this compression causing other kinkings on the oesophagus already hypokinetic because of the age (presbyoesophagus). This illness often shows scare symptoms, but sometimes requires a pneumatic dilation to allow normal food assumption of the patient. The authors report on their experience of two cases, clearly documented from the diagnostic point of view; the first one was given medical treatment, the second one was treated with a pneumatic dilatation of the cardias.

[Reappearance of esophageal peristalsis after treatment of achalasia. Reality or artifact?].

The authors discuss the question of the reappearance of esophageal peristalsis following surgical or dilating treatment in patients with a diagnosis of cardiospasm. On the basis of their experience and an extensive review of the literature, the authors affirm that the reappearance of motor activity should not be attributed to a condition of pure achalasia but rather to an intermediate motor disorder with pseudo-achalasic characteristics which are difficult to discriminate.

The paper report the case of a patient brought to the Authors' attention suffering from megaesophageal cardial achalasia who had already undergone gastroduodenal resection according to BII. It was considered worthwhile to report this case due to the problems which arose concerning the choice of a thoracic rather than abdominal route owing to the impossibility of associating cardiomyotomy with anti-reflux plastica surgery because of the reduced dimensions of the stomach.

[Leiomyoma of the esophagus].

In this paper the Authors report a review of the clinical records from 1972 to 1985 of the Institut of IV Clinica Chirurgica of Rome of esophageal leiomyoma. We report on 7 cases: three males and four females. Their ages ranged from 37 to 78 years (mean 54 years). The most frequent symptoms were dysphagia (71.4%), loss weight (57.1%) and slight epigastralgia (42.8%). Barium meal, esophagoscopy, esophageal manometry, TAC are the most sensitive procedures for a correct preoperative diagnosis. The therapy of choice is surgical treatment. However surgery is conservative: extramucosal enucleation of the leiomyoma is the procedures of choice. The postoperative course was free of complications, the long-term results were excellent.
