Improving results of esophageal stenting: a study on 160 consecutive unselected patients.

BACKGROUND AND STUDY AIMS: Esophageal stenting is a valuable treatment in the management of malignant dysphagia. Recently, self-expanding stents have proved effective in reducing morbidity and mortality. The aim of this study was to evaluate the early and late results of esophageal stenting in a series of 160 consecutive unselected patients with unresectable esophageal and cardial carcinoma treated between November 1992 and December 1996. PATIENTS AND METHODS: The procedure was successful in 159 patients (99.4%). A traditional tube was employed in 84 patients (52.5%). Metallic self-expanding stents have been available since June 1993 and were used in 75 selected patients (46.9%). The tumor was located in the cervical, upper, middle and lower thoracic esophagus, and at the gastric cardia in 16, 16, 56, 22 and 34 patients, respectively. In the remaining 15 patients an esophagovisceral anastomosis was involved. Preoperative chemo- and/or radiotherapy were performed in 82 patients (51.3%). RESULTS: Overall hospital morbidity was 11.3% (18/159) and included four dislodgments, four incomplete expansions of a self-expanding stent, two perforations, two incomplete sealings of a malignant respiratory tract fistula, two hemorrhages, two persistent foreign body sensations, one arrhythmia and one aspiration pneumonia. Hospital mortality was 1.3% (2/159) and was recorded in patients who underwent traditional intubation. At discharge, dysphagia was improved at least 2 degrees in 152 patients (96.8%). The overall long-term morbidity was 23.5% (37/157). Mean survival after the procedure was 4.7 months. CONCLUSIONS: Intubation is a safe palliative procedure which can be performed with low morbidity and mortality rates. Self-expanding metallic stents have enhanced the indications and the outcomes of the procedure, resulting in the treatment of strictures where the placement of a traditional tube is difficult or technically impossible.

Prevalence, management and outcome of early adenocarcinoma (pT1) of the esophago-gastric junction. Comparison between early cancer in Barrett's esophagus (type I) and early cancer of the cardia (type II).

The study compares, in true adenocarcinoma of the cardia and in adenocarcinoma in Barrett's esophagus, the prevalence of early cancers and their outcome in those patients suitable for resection surgery. From 1980 to 1993, 26 of 350 (7.4%) resected adenocarcinomas of the esophago-gastric junction were pathologically staged as early cancer or pT1. The prevalence of early cancer was 3.7% (11/294) for true cancer of the cardia and 27% (15/56) for cancer in Barrett's esophagus (P < 0.001). Ten of the 15 latter cancers were diagnosed during endoscopic surveillance for benign Barrett's esophagus. Among early cancers, there were four mucosal and 22 submucosal tumours; of the latter, eight had lymph node metastasis and seven neoplastic permeation of lympho-hematic vessels. The most frequently used surgical procedure was esophago-gastric resection and gastric pull-up. Postoperative morbidity was 15.4%, and hospital mortality 3.8%. Excluding postoperative deaths, the overall 5-year survival rate was 79% for early cancer of the cardia and 83% for early cancer in Barrett's esophagus (log rank test = 0.0214, P = 0.88). Overall, the survival rate was 100% in the absence of lymph node metastasis and 43% in the presence of node metastasis (log rank test = 15.811, P = 0.0001). Only one of five patients with both node metastasis and vessel infiltration survived longer than 5 years. In conclusion, the prevalence of early cancer was significantly greater for cancer in Barrett's esophagus than for true cancer of the cardia. Prognosis of the two types of tumour after resection surgery was the same and depended on lymph node status and neoplastic permeation of lympho-hematic vessels.

First-line chemotherapy improves the resection rate and long-term survival of locally advanced (T4, any N, M0) squamous cell carcinoma of the thoracic esophagus: final report on 163 consecutive patients with 5-year follow-up.

OBJECTIVE: The objective of this prospective, nonrandomized study was to evaluate the immediate and long-term results of first-line chemotherapy and possible surgery in locally advanced, presumably T4 squamous cell esophageal cancer. SUMMARY BACKGROUND DATA: Locally advanced esophageal cancer is rarely operable and has a dismal prognosis. For this reason, neoadjuvant cytoreductive treatments are more and more frequently used with the aim of downstaging the tumor, increasing the resection rate, and possibly improving survival. METHODS: From January 1983 to December 1991, 163 consecutive patients with a presumedly T4 squamous cell carcinoma of the thoracic esophagus (group A) received on average 2.5 cycles (range, 1-6) of first-line chemotherapy with cisplatin (100 mg/m2 on day 1) and 5-fluorouracil (1000 mg/m2 per day, in continuous infusion from day 1 through day 5). Chemotherapy was followed by surgery when adequate downstaging of the tumor was obtained. RESULTS: Chemotherapy toxicity was WHO grade 0 to 2 in 80% of cases, but 3 toxic deaths (1.9%) occurred. Restaging suggested a downstaging of the tumor in 101 of 163 patients (62%), but only 85 patients (52%) underwent resection surgery; it was complete or R0 in 52 (32%) and incomplete or R1-2 in 33. Overall postoperative mortality was 11.7% (10 of 85), morbidity 41% (35 of 85). Complete pathologic response was documented in 6 patients, and significant downstaging to pStage I, IIA, or IIB occurred in 25 more patients. The overall 5-year survival was 11 % (median, 11 months). After resection surgery, the 5-year survival was 20% (median, 16 months); none of the nonresponders survived 4 years after palliative treatments without resection (median survival, 5 months). The 5-year survival rate of the 52 patients undergoing an R0 resection was 29% (median, 23 months). Stratifying patients according to the R, pT, pN, and pStage classifications, the survival curves were comparable to the corresponding data obtained in the 587 group B patients with "potentially resectable" esophageal cancer who underwent surgery alone during the same period. Furthermore, the results were improved in comparison with 136 previous or subsequent patients with a locally advanced tumor who did not undergo neoadjuvant treatments (group C). In these patients, the R0 resection rate was 7%, and the overall 5-year survival was 3% (median, 5 months). CONCLUSION: Although nonrandomized, these results suggest that in locally advanced esophageal carcinoma, first-line chemotherapy increases the resection rate and improves the overall long-term survival. In responding patients who undergo R0 resection surgery, the prognosis depends on the final pathologic stage and not on the initial pretreatment stage.

Prognosis of early squamous cell carcinoma of the esophagus after surgical therapy.

Between 1980 and 1995, 91 (13.7%) out of 666 patients were determined by pathologic staging to have a superficial squamous-cell esophageal carcinoma of the thoracic esophagus. The male to female ratio was 3.3:1, and the mean age 60 years. Postoperative mortality was 4.3%. The median follow-up was 48 months (range 3-179). Survival was significantly decreased with increased depth of tumour invasion and presence of nodal metastases (P=0.03). Recurrent disease was prevalent in patients with submucosal tumours compared to those with mucosal tumours (P < 0.05). Only intra-epithelial and intramucosal carcinomas deserve the definition of 'early' tumours. Given the relative inaccuracy of current staging modalities and the low morbidity and mortality rates associated with surgical resection, surgery appears to be the mainstay of treatment of superficial squamous-cell esophageal cancer.

[Video laparoscopic surgery and rectal prolapse. Our experience in rectopexy].

BACKGROUND: Laparoscopy is gaining an important role in the treatment of benign colorectal disorders. The aim of this study is the evaluation of clinical and functional results in 4 patients submitted to a laparoscopy rectopexy according to Wells. METHODS: Four females (22-76, mean 53.7 years) affected from a total rectal prolapse with fecal incontinence underwent this procedure from 1993 through 1995. Six months after surgery, at the end of a rehabilitation program consisting of kinesitherapy, bio-feedback and electrostimulations, all patients have been re-evaluated by means of a clinical exam, anorectal manometry, defecography. RESULTS AND CONCLUSIONS: Preliminary results seem satisfactory and may allow to prefer this approach instead of the traditional open one.

[The value of extensive lymphadenectomy in cancer of the lower esophagus and cardia].

Between 1980 and 1997, 1194 patients with a malignant tumor of the lower esophagus have been observed and treated in our Institution. There were 555 patients (46.5%) presenting with squamous-cell carcinoma, 101 (8.5%), with Barrett's adenocarcinoma and 538 (45%) with cardia adenocarcinoma. Most patient underwent a transthoracic esophagectomy with esophagogastroplasty; transhiatal approach was mainly reserved to high-risk patients. Over the past two years sixty-three patients (42 with adenocarcinoma and 21 with squamous cell carcinoma) underwent enlarged mediastinal lymphadenectomy. Three patients (4.7%) died post-operatively: one sepsis, in pulmonary embolism and one myocardial infarction. Four patients (6.3%) developed pulmonary complications: no patient had recuriential palsy. Pathologic exam revealed 1342 nodes (807 thoracic and 827 abdominal). Twenty patients (31.7%) had mediastinal nodal metastases, of which 8 in the upper mediastinum. Median follow-up was 19 months (2-36 months). Seven of the sixteen patients with recurrent disease (12 systemic, 3 mediastinal and 1 anastomotic) died. The number of metastatic nodes increased with serial section and even more with immunohistochemical staining technique (from 11.7% to 13% to 15.5%, respectively). Two patients were up-staged from M0 to M1 because of peripancreatic nodal micrometastases. We conclude that enlarged mediastinal lymphadenectomy allowed to detect upper mediastinal lymph node metastases in 12.8% of patients without increasing post-operative complication rate. A longer follow-up is required to evaluate the impact on long term survival.

Experimental oesophagogastric anastomosis: preliminary report of a new compression device that also fragments.

Fifteen Beagle dogs underwent oesophagogastric anastomosis with a new device which enables a 'sutureless' compression anastomosis. The device fragmented and was passed in bits anally without causing obstruction. Immediate bursting pressure, tested in five dogs, was between 175 and 190 mmHg. The anastomoses of the remaining dogs were examined macroscopically and microscopically from day 6 to day 30. Healing was excellent with good muscular apposition and minimal residual inflammation.

Biochemical assay of collagen and elastin in the normal and varicose vein wall.

Alterations of the connective tissue in the varicose vein wall have been noted by several investigators; however, the cause of the vein dilatation has still not been established. The aim of this study was to find a biochemical explanation to the development of varices by evaluating sensitive biochemical markers of collagen and elastin in the varicose vein wall. 4-L-Hydroxyproline (HYP), as a marker of collagen content, and desmosine (DES) and isodesmosine (IDES), as markers of elastin, were measured in 47 macroscopically dilated and 32 nondilated segments of 20 varicose saphenous veins collected from 20 patients with varices. The same measurements were made in 24 fragments of normal saphenous veins collected from 14 patients in whom the vein was removed to be used for graft procedures. HYP (collagen) and DES and IDES (elastin) were determined with a colorimetric method and HPLC, respectively. ANOVA test was used to compare mean values (+/- SD). HYP and collagen content were similar in varicose and normal veins. There was a significant reduction of both DES and IDES in dilated segments of varicose veins (P < 0.05 vs normal veins and nondilated segments); the ratio of elastin to collagen was lower in varicose than normal veins (P < 0.05), and this reduction was most significant in the dilated segments (P < 0.01 vs normal veins). These results suggest that dilatation of the varicose vein wall may be related to some defect of elastin metabolism. Further studies on the metabolic activity of vein muscle cells are required.

Endoscopic management of inveterate esophageal perforations and leaks.

The endoscopic management of four selected patients with inveterate esophageal perforations or leaks is presented. One patient had a perforation of the cervical esophagus following endoscopic removal of a foreign body already treated with surgical drainage; two patients had a leak following diverticulectomy and esophagogastrostomy, respectively, persistent after multiple surgical repairs; the last patient had a spontaneous perforation of the thoracic esophagus persistent after two transthoracic repairs. The mean time elapsed between the diagnosis of perforation and the endoscopic treatment was 19 days. In one patient, transesophageal drainage of a mediastinal abscess was performed. In the other three patients, a stent was placed to seal the leak in combination with gastric and esophageal aspiration. Two of these patients underwent endoscopy in critical condition and could have not been candidates for major surgical procedures. All patients received enteral nutrition. No morbidity or mortality related to the endoscopic procedure was recorded; the treatment was effective in all patients who recovered and resumed oral feeding within 3 weeks. We conclude that endoscopic transesophageal drainage and stenting are effective procedures in the management of patients with inveterate esophageal perforations or leaks.

Laparoscopic treatment of paraesophageal and large mixed hiatal hernias.

BACKGROUND: Laparoscopic treatment of large mixed hiatal hernias was attempted in eight patients. METHODS: One patient (12.5%) was converted to open surgery due to difficulty in repositioning the LES into the abdomen resulting from a shortened esophagus. One left pleural tear occurred intraoperatively and was repaired without further consequence. Median duration of the operation was 150 min (range 120-300 min). RESULTS: No postoperative complications were recorded. All patients are asymptomatic after a median follow-up of 14 months (range 7-15 months). Correct repositioning of the stomach was confirmed by radiological evaluation 1 month after surgery. Early functional results are good. (One asymptomatic gastroesophageal reflux was detected and medical treatment was undertaken). CONCLUSIONS: Laparoscopic crural repair and fundoplication are feasible even in paraesophageal and large mixed hiatal hernias. Advantages of the minimally invasive approach are clear in terms of morbidity, patient comfort, and duration of hospital stay. Nevertheless, long-term assessment is required to confirm the effectiveness of the laparoscopic approach in patients with large mixed hiatal hernias.

Prognostic value of ploidy, cell proliferation kinetics, and conventional clinicopathologic criteria in patients with colorectal carcinoma: a prospective study.

PURPOSE: The aim of this study was to obtain additional biologic determinants that may be of use in segregating into subgroups with different prognosis patients with similarly staged colorectal cancers. METHODS: Between 1989 and 1991, a prospective study of prognostic factors has been performed in a group of 98 consecutive, unselected patients who underwent curative resections for primary untreated large bowel carcinoma. The fate of all patients is known at three years after operation. Clinical and pathologic data were recorded at the time of presentation and operation, and patients have been the subjects of regular follow-up. Tumor DNA content was determined by flow cytometry, and cell proliferative activity was determined by autoradiography with tritiated thymidine labeling index (LI). RESULTS: Univariate analysis revealed that the most important predictors of survival (P < 0.001) were the presence of positive lymph nodes, the presence of preoperative complications, Dukes stage, and LI. The multivariate analysis showed that Dukes stage (P < 0.002) and LI (P < 0.0001) were the only factors significantly related to survival. Disease-free survival was influenced significantly by Dukes stage (P < 0.001), LI, according to the classification in the two groups of high and low proliferative activity, respectively, (P < 0.0001), LI, calculated as a continuous variable (P < 0.0002), and the presence of lymph node metastases (P < 0.003). Outcome (favorable/unfavorable) was influenced significantly by Dukes stage (P < 0.0001) and LI (P < 0.0001). Concordance for each patient between Dukes stage and outcome was 73.1 percent and between LI, calculated as a continuous variable, and outcome was 74.1 percent. If, on the other hand, Dukes stage and LI are used together, concordance with outcome reaches 89.2 percent. CONCLUSION: We can conclude that, from a practical point of view, LI is an essential factor that must be combined with pathologic variables for a better prediction of patient outcome.

Continent perineal colostomy by electrostimulated graciloplasty in abdominoperineal resection. A preliminary report.

Despite the tendency toward sphincter-saving surgical procedures, a small proportion of rectal cancers must still be treated by abdominoperineal resection (APR). The physical, psychological and social consequences of a permanent abdominal stoma are a challenge to perform a continent perineal colostomy. Most of the attempts originate from experiences with gracilis muscle transposition in the treatment of fecal incontinence, in particular Pickrell's operation. Functional results are however conditioned by the fact that the transposed muscle takes up a different function and its natural evolution, if not adequately stimulated, consists of atrophy and fibrosis. The most important series of graciloplasty in APR is reported by Cavina and coworkers (75 cases from 1985 to 1993), who at first obtained good functional results by external electromyostimulation (EMS) and biofeedback, then registered a further improvement using internal, continuous low-frequency EMS by implantable pulse generators (IPG). The surgical technique involves, after APR: bilateral dissection of the gracilis up to the proximal neurovascular pedicle and detachment of the distal tendon; mobilization of the muscles, through the subcutaneous tissue, into the perineum, where the colonic stump is drawn out; positioning the right gracilis behind the colonic stump, as a puborectalis sling, and the left gracilis around it, in a sort of "alpha" configuration; suturing the colonic stump to the perineal skin; optionally, temporary diverting loop colostomy. The operation is completed by the insertion of two electrodes near the nerve, for external or internal EMS (in the last case: implantation of IPG). The external EMS may be carried out by current cardiac temporary electrodes, drawn up through the skin of the iliac area. It is aimed at preserving the trophism and the contractility of the muscle and enabling the patient to learn a new function of continence (actually, it is a "pseudocontinence"), thanks to a program of intermittent stimulation and biofeedback. Electrodes and other devices are not expensive. The internal EMS requires specific electrodes, connected to an IPG, implanted in a subcutaneous abdominal pocket. The continuous stimulation gives rise to a tonic activity of the gracilis, resulting in higher resting anal pressure and "true" continence. The IPG is programmed under telemetry control, step by step until the most suitable EMS parameters are reached. A magnet allows the patient to turn the IPG "off" of "on", according to the necessity to void the bowel. A complete set of 1 IPG and 2 electrodes costs about $10,000. Cavina reports good continence in 71% of the cases treated by external EMS and 100% of the patients with IPG. Our first graciloplasty in APR was performed in April 1994. Since then we have carried out 6 operations. Because of its high cost, we decided that, at least at a first phase, the IPG should be implanted, from the 7th month on, only in disease-free patients, when functional results suggested a possible clinical improvement. Until today, 3 patients have had the abdominal stoma closed and can be evaluated from a functional viewpoint. We recorded 1 "excellent" and 2 "fair" results. In the two patients with a "fair" result we implanted a pulse generator about a month after the closure of the abdominal colostomy. A good manometric and clinical improvement was registered. The patient with "excellent" functional result had a recurrence one month after the closure of the stoma. Though limited, our experience is absolutely favourable as to graciloplasty, but an evaluation from us whether external or internal EMS is better, is too early at the moment. In absolute functional terms, the internal, continuous EMS is preferable, but problems of cost and oncologic prognosis restrict the use of IPG.

A special instrument for a safe and effective laparoscopic esophageal myotomy.

The authors describe the use of particular endoscopic scissors that allow a safe and easy laparoscopic performance of Heller myotomy. Although originally designed for another use, these scissors are extremely useful for esophageal myotomy, their most important feature being the smooth and insulated protection of the lower jaw. This feature keeps the mucosa constantly away from the myotomy and allows the safe use of electrocautery, resulting in a perfect hemostasis.

Mediastinal cyst involving the oesophagus: diagnosis and results of surgical treatment.

OBJECTIVE: To describe our experience with mediastinal cysts involving the oesophagus. DESIGN: Retrospective study. SETTING: University hospital, Italy. SUBJECTS: 11 patients who presented to our department with a mediastinal cyst from 1976-1994. INTERVENTIONS: Excision of the mass through a posterolateral thoracotomy (n = 10) or by video-assisted thoracoscopy. MAIN OUTCOME MEASURES: Morbidity and mortality. RESULTS: 8 patients presented with retrosternal or epigastric pain, three of whom had mild dysphagia. In the remaining 3 the tumour was asymptomatic and an incidental finding on a chest radiograph. Endoscopic ultrasonography and computed tomography (CT) allowed preoperative diagnosis of an extramucosal cyst in 5 of the 7 patients investigated by both tests. Masses were excised through a formal thoracotomy (n = 10) or by video-assisted thoracoscopy. Histological examination confirmed a benign cyst in all cases. There was no operative morbidity and nine patients are free of symptoms after a median follow-up of 2.3 years. CONCLUSION: Excision, preferably by thoracoscopy, is the treatment of choice for mediastinal cysts that involve the oesophagus. Special attention should be paid to the vagal nerves, and as many as possible of the muscular layers of the oesophagus should be preserved.

Lack of allelic loss at the multiple endocrine neoplasia type 1 (MEN-1) gene locus in a pancreatic ductal (non-endocrine) adenocarcinoma of a patient with the MEN-1 syndrome.

The gene responsible for multiple endocrine neoplasia type I (MEN-1) syndrome has been mapped to chromosome 11q13. It appears to function as a tumour-suppressor gene analogous to that for retinoblastoma and allelic losses involving the wild-type of the MEN-1 allele have been found in parathyroid and pancreatic endocrine tumours of MEN-1 patients. No genetic information has been provided so far on non-endocrine malignancies that may occur in MEN-1 patients. A case of exocrine pancreatic adenocarcinoma presenting as the terminal event in a woman with a long standing history of MEN-1 syndrome and multiple endocrine tumours of the pancreas was investigated for possible allelic losses at the MEN-1 gene locus using restriction fragment length polymorphisms (RFLPs) closely linked to the MEN-1 gene and polymerase chain reaction (PCR) for D11S533 locus. No allelic losses were found in tumour tissue with two informative RFLPs (D11S97, D11S146) or with PCR analysis. These findings suggest that the MEN-1 gene does not confer a predisposition to develop tumours other than those that typify the syndrome.

Esophageal achalasia: laparoscopic versus conventional open Heller-Dor operation.

BACKGROUND: The laparoscopic treatment of esophageal achalasia has recently been introduced, and the occasional reports in the literature seem to indicate considerable advantages for patients in terms of surgical trauma, postoperative discomfort, and appearance. As yet, however, no studies have directly analyzed the benefits and shortcomings of the new surgical technique by comparison with the conventional open procedure. The objective of our study was to review recent experience with the laparoscopic Heller-Dor operation (LAP-HD) at the Department of Surgery of Padua University and compare it with the traditional open Heller-Dor procedure (OPEN-HD) to assess early effectiveness in patients with primary esophageal achalasia. PATIENTS AND METHODS: The records of 17 patients who had LAP-HD and a matched group of 17 patients who had OPEN-HD were retrospectively reviewed. The duration of procedures, morbidity, several aspects of the postoperative course, and hospital costs were recorded and compared. Results of clinical follow-up and of manometric and pH-monitoring studies performed 6 months postoperatively were also evaluated in both patient groups. RESULTS: LAP-HD took longer than OPEN-HD (mean 178 versus 125 minutes). There was no mortality or major morbidity in either group. Postoperative pain and ileus and need for IV nutrition lasted a shorter time for LAP-HD patients (P < 0.0001). Consequently, the median postoperative hospital stay and the median interval before returning to normal activity were also shorter (4 and 14 days for the LAP-HD group versus 10 and 30 days for the OPEN-HD group, P < 0.0001). During follow-up, dysphagia recurred in 1 patient of the LAP-HD group and gastroesophageal reflux was registered in 1 patient of the OPEN-HD group. Lower esophageal sphincter pressure decreased significantly after both procedures. CONCLUSIONS: Laparoscopic management of achalasia leads to short-term results comparable to those of the well-established open technique. In view of the less severe surgical trauma and lower hospital cost, the laparoscopic approach is preferable, but long-term studies are needed.

Laparoscopic approach to esophageal achalasia.

Certain technical details are considered important to ease the laparoscopic performance of a Heller myotomy combined with a Dor antireflux procedure for esophageal achalasia. A special emphasis is given to intraoperative esophagoscopy combined with a mild balloon distension of the esophagogastric junction. These maneuvers prove helpful in identifying the esophagogastric region, easing the myotomy, and controlling its completeness.

Efficacy of octreotide in the prevention of pancreatic fistula after elective pancreatic resections: a prospective, controlled, randomized clinical trial.

BACKGROUND: A prospective, randomized controlled clinical trial was conducted in 33 Italian surgical departments with the aim of evaluating the efficacy of octreotide in the prevention of pancreatic fistula after elective pancreatic resections. METHODS: Between July 1990 and May 1992, 278 patients were enrolled in the study. Fifty-four dropped out because of unresectable disease and six were excluded because of protocol violation; the remaining 218 were randomly assigned to the octreotide group (n = 111) or to the placebo group (n = 107). There were 131 men and 87 women with a mean age of 58.2 +/- 11.7 yrs. Pancreaticoduodenectomy was the most common operation performed (n = 143), sixty-four percent of patients had a pancreatic or periampullary cancer; chronic pancreatitis accounted for 8.2% of cases. RESULTS: Mortality rate was 6.9%. A pancreatic fistula occurred in 31 patients (14.2%), 9% in the octreotide group and 19.6% in the placebo group (p < 0.05). Morbidity rate was significantly lower in the octreotide (21.6%) than in the placebo group (36.4%) (p < 0.05). When specific pancreatic complications were grouped together and evaluated, they occurred less frequently in the treated (15.3%) than in the placebo group (29.9%) (p < 0.05). CONCLUSIONS: Octreotide was able to reduce significantly the incidence of pancreatic fistula after elective pancreatic resections.
