[Isolation of the lower esophagus and fundus of the stomach by specially designed forceps to avoid ectopic embolization during the process of coronary venous embolizing therapy].

To avoid ectopic embolization occasionally occuring in embolization therapy of coronary vein of the stomach, the authors designed forceps to temporarily isolate the lower esophagus and the gastric fundus. A series of 61 patients with portal hypertension were treated with this method from march 1990 to march 1994 with no ectopic embolization. The operative mortality was 1.6%. The patients were followed up for six months to 4.5 years, with a rebleeding rate of 6%, and an improved varices in 85.4% of all cases. This is a reliable method to avoid ectopic embolization and the individualization of embolitic dosage.

[TV-assisted thoracoscopic surgery with a lung forceps combined with thoracoscope under local anesthesia for spontaneous pneumothorax with a persistent air leak--a single access port approach].

TV-assisted thoracoscopic surgery was performed under local anesthesia by through a single access port to control a continuing air leak in spontaneous pneumotorax. A 75-year-old man was admitted with severe dyspnea and right-sided chest pain. The chest X-ray film showed right lung collapse. A right spontaneous pneumothorax was diagnosed and was treated by chest tube drainage. However, the lung did not re-expand because of a continuing air leak and subcutaneous emphysema developed. TV-assisted thoracoscopic surgery was performed under local anesthesia to treat the persistent air leak on day 12. By endoscopy, the ruptured bulla was double-ligated with an Endoloop through a single access port using lung forceps combined with endoscope. The air leak subsequently ceased and the lung re-expanded. This method is minimally invasive and is very suitable for controlling a continuing air-leak causing spontaneous pneumothorax in a patient.

First trimester prenatal diagnosis by transcervical chorionic villus sampling using curved biopsy forceps: lessons of the first 30 continuing pregnancies.

Transcervical chorionic villus sampling was performed on 30 pregnancies who were at risk for chromosomal abnormalities between 9 and 12 weeks of gestation to determine whether the developing fetus had a chromosomal disorder. Curved biopsy forceps were passed transcervically into the chorion frondosum under continuous real-time ultrasound guidance, and chorionic villi were biopsied. Chorion yield was assessed semiquantitatively. An adequate villus sample was obtained in all cases, giving a success rate of 100 per cent. The average weight of the villi was 18.8 mg with a lower limit of 10 mg which proved sufficient for diagnostic purposes. The villi were processed for chromosomal analyses by cultured preparations. A diagnostic result was achieved in 28 of cases (93.3%) within 2 weeks. No major maternal complications were encountered. The fetal loss rate was 3.3 per cent. No fetal anomalies were found in the study group. It is concluded that transcervical chorionic villus sampling appears to be a relatively safe and reliable procedure, but the risk of miscarriage can only be accurately assessed after further investigation. In contrast to amniocentesis, the procedure is performed early in pregnancy and results of the genetic test are available during the first trimester. We believe that transcervical chorionic villus sampling offers an alternative to amniocentesis in the detection of genetic disorders.

[Bronchial lipoma removed with bronchoscopic snaring forceps].

A 62-year-old woman was admitted to the hospital because of dyspnea. A chest X-ray film showed a massive left pleural effusion. Thoracentesis was done and purulent fluid was found. Streptococcus intermedius was detected in the fluid. Chest drainage and administration of antibiotics were successful, but computed tomography of the chest revealed a mass in the left main bronchus. The mass was removed with transbronchial electrosurgical snaring forceps and was found to be a lipoma. This tumor had low CT numbers (from -70 HU to -140 HU), and this finding may be useful in the differential diagnosis of endobronchial tumors.

Value of a single forceps biopsy of colonic polyps.

The accuracy of colonoscopic biopsies in predicting the histological diagnosis of colonic polyps removed at colonoscopy or at laparotomy was studied. Forty-two patients were colonoscoped before the removal of 50 polyps. A single fractional biopsy was obtained from each lesion with the standard endoscopic biopsy forceps and was compared to the final histological diagnosis of each excised lesion. Thirteen (26%) of the singular fractional biopsies did not demonstrate the significant histological features of the excised polyps. These tiny biopsies do not adequately represent the entire polyp. Moreover, the 2- to 3-mm size of the biopsy does not permit the study of the central submucosal area of the polyp stalk, the critical area for assessing invasive malignancy. Histological examination of a completely excised polyp is essential for accurate diagnosis and appropriate therapy.

[Vascular microanastomosis by eversion and stapling using VCS forceps. Presentation of the technique and experimental evaluation of its reliability].

With the objective of further improving the reliability of microvascular anastomoses, several different procedures are now available to microsurgeons, including eversion-stapling by VCS forceps. The authors start by presenting the technique, emphasizing the need for specific instruments and compliance with certain principles determining the success of these anastomoses. In the context of an experimental protocol in the pig, on vessels measuring an average of 2.5 mm in diameter, 80 anastomoses were performed by VCS stapling-eversion and studied clinically, histologically and ultrastructurally, comparing the results to those of conventional anastomoses by approximation-suture with needle and suture. In light of the results, eversion-stapling anastomoses appear to be more reliable due to the absence of intraluminal foreign body, permanent endothelial continuity and effective re-endothelialisation before day 7.
