摘要:

AbstractA prospective study was performed analyzing resected extrapulmonary lymph nodes of 544 operated lung carcinoma patients. Volume of lymph nodes was determined by weight. Lymph nodes were cut in serial sections 300 μm thick, and the volume of tumour metastasis in each resected lymph node was computed measuring the tumourous area in the lymph node sections. The following results were obtained: Percentage of resected lymph nodes varied with lymph node site and site of the primary lung cancer. Hilar lymph nodes were resected in 50% of the patients, lymph nodes of the main and stem bronchi in 57% and 63%, respectively. Tumour metastases were found in 10%‐15% of the resected lymph nodes. The size of the lymph nodes varied to a large amount and was found to be independent of the lymph node site if no metastases could be detected. Lymph nodes measuring10 ccm) in 62% of the cases (20/32). Tumourous involved lymph nodes of the main bronchus were found more frequently in cases of central localized lung cancer compared to carcinoma arising from the peripheral lung, where the opposite was seen in subaortal located lymph nodes. The percentage of lymph node involvement and size of tumour infiltrated lymph nodes was found to be independent of tumour cell type. Size of resected lymph nodes is not a reliable parameter for estimating existence of tumour infiltratio

摘要:

AbstractPostoperative anastomotic leakage is one of the most dangerous and, unfortunately, most frequent complications. Many methods have been tried to prevent such leakage. The incidence of leakage has decreased to 3.84% in our hospital in recent years. Ten cases of gastroesophageal anastomotic leakage following resection of carcinoma of the esophagus and gastric cardia are analyzed and a new tool, the three‐leaf clamp, which reduced the anastomotic leakage, is introduce

摘要:

AbstractOf 6,426 colonoscopies performed in 1978–1987, 66 invasive colorectal adenomatous polyps were removed in 58 examinations. The study group included 36 (62%) men and 22 (38%) women with an age range of 42–96 years. Forty‐three patients had invasive pedunculated polyps and 15 had invasive sessile polyps. Following the colonoscopic polypectomy, secondary surgical resection was done in 19 patients with pedunculated polyps and in 13 patients with sessile polyps. The operative specimens showed that the colonoscopic polypectomy removed the entire cancerous focus in all patients with pedunculated polyps, including those with stalk invasion. In contrast, most cases with sessile polyps turned out on operation to be Dukes' B or C carcinoma. Follow‐up (mean 4.4 years) was available for 53 (93%) patients: none of 24 unoperated patients with pedunculated polyps suffered from local recurrence. We conclude that colonoscopic polypectomy is sufficient for invasive pedunculated polyps, provided that histology shows that the resection margins are free of tumoral cells. Surgery is recommended for all invasive sessile

摘要:

AbstractCystadenocarcinoma of the pancreas is generally considered to be unresponsive to chemotherapy and radiation therapy. We present two cases of laparotomy‐proven unresectable cystadenocarcinoma which responded to intravenous 5‐fluorouracil (1,000 mg/m2/24 hr × 5 days × 2) and 4,000 rads of radiation therapy. Both patients had objective response with marked shrinkage of the tumor as determined by clinical examination and computed tomography. At reexploration both tumors had become completely resectable with histologically clear margins and negative lymph nodes. Carcinoembryonic antigen (CEA) levels were elevated in both patients at initial presentation (86 and 71 ng/ml). The CEA levels declined to 19.9 and 66.0 ng/ml, respectively, after neo‐adjuvant therapy, and both fell to normal levels after resection. Although surgical resection has been considered the only curative therapy for patients with pancreatic cystadenocarcinoma, we suggest that preoperative irradiation and chemotherapy may reduce the size of seemingly unresectable tumors. We also recommend serial CEA determinations in patients with levels initially elevated as a marker of the response to neo‐adjuvant and operativ

摘要:

AbstractMalignant struma ovarii is an extremely rare tumor. Two new cases are described and current perspectives provided. Both cases are examples of the mixed form of the disease, and both were treated by surgery alone. One patient underwent total hysterectomy and bilateral salpingo‐oophorectomy; the other had unilateral salpingo‐oophorectomy. Both patients remained free of recurrent disease at 20 and 33 months from diagnosis. The controversies relating to therapy and diagnosis are discussed in det
