Laparoscopic Heller myotomy with or without partial fundoplication: a matter of debate.

AIM: To present our experience of laparoscopic Heller stretching myotomy followed by His angle reconstruction as surgical approach to esophageal achalasia. METHODS: Thirty-two patients underwent laparoscopic Heller myotomy; an anterior partial fundoplication in 17, and angle of His reconstruction in 15 cases represented the antireflux procedure of choice. RESULTS: There were no morbidity and mortality recorded in both anterior funduplication and angle of His reconstruction groups. No differences were detected in terms of recurrent dysphagia, p.o. reflux or medical therapy. CONCLUSION: To reduce the incidence of recurrent achalasia after laparoscopic Heller myotomy, we believe that His' angle reconstruction is a safe and effective alternative to the anterior fundoplication.

Monodermal highly specialized teratoma of the ovary: a sebaceous gland tumor.

Teratomas are neoplasms that originate in pluripotential cells and contain representations of all three germ layers in a rather mature state. Specialized forms of teratoma with unilateral development of certain tissues, such as struma ovarii, argentaffin tumors, cholesteatoma, primary choriocarcinoma of the ovary, pseudomucinous cystoma and neurogenic cysts are known. In this paper we describe an ovarian teratoma consisting entirely of sebaceous glands.

[Ambulatory surgical treatment for breast carcinoma].

BACKGROUND: The aim of the study is to demonstrate the feasibility and the oncologic effectiveness of quadrantectomy plus sentinel node biopsy performed under local anesthesia, and to demonstrate the economic and psychologic advantages. METHODS: From October 1996 to March 2000, 71 patients affected with clinical T1 N0 breast cancer, underwent quadrantectomy or tumor resection plus sentinel node biopsy and clinically suspicion axillary nodes biopsy, under local anesthesia at the Casa di Cura "Villa Mafalda" in Rome. RESULTS: Twenty tumors were T1a, 26 T1b e 25 T1c. A mean of 2 sentinel nodes (range 1-4) and a mean of 8 axillary nodes were removed during the procedure. In 2 cases sentinel nodes were not identified. Intraoperative histologic examination showed metastatic sentinel nodes in 11 cases. An axillary node dissection was performed in all cases (>12 nodes) and no other metastatic nodes were found. In all patients clinically suspected nodes were removed. In two cases no evidence of metastasis was found in sentinel nodes, while histologic examination revealed in a patient micrometastasis in one node, and in another patient two metastatic nodes. CONCLUSIONS: Fifty-three patients rated the overall surgical, anesthetic and recovery experience as "very satisfactory", 13 "satisfactory" and 5 "unsatisfactory". Patients typically expressed their pleasure at the possibility to return home and stressed the ease of recovery.

Hemangioma of the breast: an unusual lesion without univocal diagnostic findings.

Hemangiomas of the breast, either capillary or cavernous, are thin-walled, blood-filled vascular spaces, separated by fibrous septa, with extensive fibrosis and sometimes phleboliths. Clinical diagnosis is rather difficult. Generally they are coincidental microscopic findings. We report herein a case of breast hemangioma misdiagnosed at ultrasound and mammography. A 63-year-old woman described intermittent sharp pain in the right breast. Physical examination, mammography and ultrasonography were not sufficient for the diagnosis. Surgical excision of the lesion was performed. At histology it was found to be a cavernous hemangioma without cellular atypia. The patient is now 9 months post surgery and is well. The role of the single diagnostic examination is limited. The Authors believe the complementary role of all available techniques in the evaluation of a breast lesion.

[Use of vascular endostapler in surgery of the lower rectum].

A practical and effective method for rapid and bloodless preparation of the rectum using endovascular stapler devices during low anterior resection, or abdominal-perineal excision, is described. This method is presented as an effective means for easily dividing the anterior and lateral attachment of the rectum. The application of this technique is the absence of intraoperative bleeding related to injury of middle hemorrhoidal vessels, with minimal risk of autonomic pelvic nerve damage. An additional factor relevant in the choice of this technique, is the easier possibility to perform rectal dissection of an oncologically adequate tumor clearance from the margin of rectal tumor and with complete radical transection of the lateral ligaments fastly proceeding with the downward mobilization of the rectum close to the pelvic side walls, between the parietal and visceral layer of the pelvic fascia.

Alternative insertion sites for permanent central venous access devices.

Permanent central venous access devices (PCVAD) are used widely in the management of chronically ill patients, particularly in neoplastic diseases. The standard approach consists of positioning the catheter in the superior vena cava (SVC) either using subclavian or internal jugular vein puncture, or cephalic or external jugular vein cut-down, with the port implanted in a subcutaneous pouch of the thoracic region. Alternative insertion sites could be used in selected cases. In our experience, consisting of 158 PCVAD, 12 cases required a different insertion site: six cases of an SVC catheter and port on the forearm using a basilic vein cut-down, and six cases of an inferior vena cava (IVC) catheter and port in the abdominal region using a great saphenous vein cut-down. Comparing standard to alternative approaches, we observed a total morbidity rate of 8.9% and 8.3%, respectively (P=NS), while the explant rate was 5.4% vs 8.3% (P=0.1). Our data show non-significant differences in morbidity and explant rates between the two groups of patients. Alternative insertion sites for the PCVAD implant seem to be a valid possibility in the management of chronically ill patients.

[Carcinoma of the gastric stump. Our experience in 28 treated cases].

A chart review was conducted on 28 patients with gastric stump cancer who were radically treated at the First Department of Surgery of University "La Sapienza" of Rome between 1978 and 1990. The data obtained were compared with those of 401 patients radically treated, in the same period, for primary cancer of the proximal third of the stomach. There were no significant differences between the two groups in terms of stage and nodal involvement. Surgical treatment was total gastrectomy in 86% of cases, and an extended procedure in 57% of patients. The morbidity rate was similar to patients treated for primary gastric cancer, as well the 5-year survival, which depend on the stage of disease. We can conclude that gastric stump cancer must be treated surgically with radical intent as the prognosis is similar to that of primary gastric cancer.

[Biliary tract surgery in patients of 70 and older: an assessment of our experience with 100 consecutive cases].

A series of 100 consecutive patients aged 70 years and older having biliary tract lithiasis observed over a 19-year period (1970-1989) at the 1st Surgical Department of the University of Rome was analyzed in an effort to define morbidity and mortality. Eighty-eight patients underwent surgical treatment. Three patients died postoperatively (3.4%); 12 patients had local and 13 general complications. The highest incidence of complications occurred in patients with associated diseases and bacteriobilia. A long-lasting symptomatology involved a more frequent exploration of the common bile duct. Morbidity and mortality were not significantly related to the type of surgical procedure performed. Elective biliary tract surgery is a safe procedure even in aged patients.

Hepatic resections for colorectal metastases: the Italian multicenter experience.

In 1989 there were 151,000 new cases of colorectal carcinoma in the United States. Approximately 50% of these patients will be at risk of developing liver metastases together with other sites of recurrence. However, the liver will be the main site of relapse in only 14,000 patients with colorectal cancer. Approximately 25% of patients with colorectal carcinoma have technically resectable hepatic metastases at the time of operation for primary lesion, and an additional 8-25% will develop metachronous hepatic metastases after primary resection. Recent reported experiences with surgical treatment of metastatic colorectal cancer in the liver seem to indicate that hepatic resection has become more acceptable, safe and effective therapy, and offers today when technically possible, the best prospect of survival in a conspicuous number of patients. For these reasons, although a prospective randomized trial has not been done comparing resection with nonresection, resection seems to give the best hope for cure and actually is the treatment of choice for selected patients. In fact in these patients is reported a significant prolongation of survival compared with those patients with unresectable liver metastases treated only with adjuvant therapy in the form of chemotherapy or radiation therapy. Median survival of resected patients with hepatic metastases has been reported to range from 6-12 months, and for patients with single metastases is reported to range from 4.5-6.2 months to 11 and 21 months. The benefits of surgical therapy have been emphasized by different experience, with a 5-year overall survival rate ranging from 20-40%. In a recent multicenter survey a 33% 5-year survival rate was demonstrated in 859 patients resected for hepatic metastases.

Effect of preoperative colonoscopy on the incidence of synchronous and metachronous neoplasms.

Colonoscopy and air-contrast barium enema performed preoperatively in 389 patients with colorectal cancer revealed synchronous cancer in 4% and polyp in 14%. Nine of the 16 synchronous cancers were located in other surgical segments than the index cancer, and six of the nine were in stage A or B1. Of the 54 synchronous polyps, 28 were located in such other segments. Half of the synchronous cancers and almost half of the synchronous polyps were missed at double-contrast barium enema. All synchronous cancers and three-fourths of the synchronous polyps were detected at colonoscopy. No patient with preoperative colonoscopy presented with metachronous cancer within 3 years from surgery, and only two were subsequently found to have adenocarcinoma arising from an adenomatous polyp. Endoscopic polypectomy was performed in 21 cases during follow-up. Extensive use of preoperative colonoscopy is recommended in the evaluation of colorectal cancer, in order to promote detection of synchronous tumors, reduce the incidence of 'early metachronous' cancer and avoid malignant degeneration of adenomatous polyp.

The role of CEA, TPA and CA 19-9 in the early detection of recurrent colorectal cancer.

Eighty-eight consecutive patients who underwent curative resection for colorectal cancer between 1983 and 1985 were studied prospectively to evaluate the roles of sequential CEA, TPA and CA 19-9 determinations and independent clinical examination in the early diagnosis of resectable recurrences. Twenty nine recurrences were detected between 8 and 38 months after primary surgery. CEA, TPA and CA 19-9 showed a sensitivity of 72%, 62% and 38%, and a specificity of 78%, 86% and 97%, respectively. Of eight recurrences in which CEA was not raised, five induced a rise in TPA and two a rise in CA 19-9. The rise in the serum concentration of one of the three markers was the first sign of relapse in 23 (79%) patients. Two second-look laparotomies based solely on a rise in serum markers were performed. In one case diffuse recurrent disease was found, and in the other a resectable solitary hepatic metastasis was found.

Evaluation of postoperative blood coagulation changes in elderly patients undergoing major surgery.

18 elderly patients submitted to major surgery for malignancies or other disease were studied to assess the relationship between changes of blood coagulation factors and inhibitors in the early post-operative period and the appearance of lower limb deep vein thrombosis. A decrease in serum antithrombin III (AT III) Protein C antigen (PC: Ag) and Plasminogen activity (PLG) levels from the second to the fourth postoperative day, together with a simultaneous increase in serum fibrinogen (FG) and von Willebrand Factor (vWF:Ag) antigen levels was observed. In 8 patients, PC:Ag levels dropped below the limit considered at risk to develop DVT (less than 60 U/dl). A patient with the lowest PC:Ag levels had deep vein thrombosis From the analysis of data it was concluded that in the postoperative period, blood coagulation changes occur in elderly patients, predisposing to the risk of deep vein thrombosis.

Tissue CEA as prognostic indicator in a series of 31 cases of gastric cancer.

The role of tissue CEA localization as a complementary factor in prognosis of patients affected by gastric cancer is analyzed. In a group of 31 gastric tumors, tissue CEA was always present in the apical portion of the tumor cell cytoplasm and in the glandular lumen, while in 23 cases it was found in the stroma, and in superficial and deep cell cytoplasm in 26 and 20 cases respectively. The serum marker levels were over 3 ng/ml in 19 patients. A relationship between CEA localization and tumor stage was observed. The more the tumors were advanced, the more the marker was found in the stroma and in the cytoplasm of superficial and deep cells. The same was found for CEA localization and serum CEA levels. The opposite trend was evidenced for the degree of tumor differentiation. In well differentiated tumors in a high percentage of cases the marker was present in the stroma and in the cytoplasm of superficial and deep cells as compared with undifferentiated tumors. No relationship between the histologic type and CEA localization was found.
