Malignancy grading of epithelial bladder tumours. Reproducibility of grading and comparison between forceps biopsy, aspiration biopsy and exfoliative cytology.

107 bladder tumours cystoscopically suspected to be malignant were examined morphologically by forceps biopsy, aspiration biopsy and exfoliative cytology. The malignancy was graded from 0 through 4. The reproducibility of each method was established, and was found to be 80%, 65% and 90%, respectively. Exfoliative cytology underestimated the malignancy grade as compared with histopathology (59% of the malignant tumours were not jduged as malignant in the cytological grading), but showed no tendency towards overestimation and gave no falsely postiive diagnoses of malignancy. It is concluded that diagnosis of bladder tumours requires both biopsy and cytological techniques, since they proved complementary in a number of cases. Grading by aspiration biopsy is less reliable but may be of benefit in selected cases where forceps biopsy is less suitable.

Trial of a novel endoscopic tattooing biopsy forceps on animal model.

AIM: To tattoo gastric mucosa with a novel medical device which could be used to monitor and follow-up gastric mucosal lesions. METHODS: Combining endoscopic biopsy with sclerotherapy injection, we designed a new device that could perform biopsy and injection simultaneously. We performed endoscopies on a pig by using a novel endoscope tattoo biopsy forceps for 15 mo. At the same time, we used two-step method combining sclerotherapy injection needle with endoscopic biopsy. The acuity, inflammation and duration of endoscopy were compared between two methods. RESULTS: Compared with the old two-step method, although the inflammation induced by our new device was similar, the duration of procedure was markedly decreased and the acuity of tattooing was better than the old two-step method. All characteristics of the novel device complied with national safety guidelines. Follow-up gastroscopy after 15 mo showed the stained site with injection of 1:100 0.5 mL of India ink was still markedly visible with little inflammatory reaction. CONCLUSION: Endoscopic tattooing biopsy forceps can be widely used in monitoring precancerous lesions. Its safety and effectiveness has been established in animals.

First-trimester transcervical chorionic villus sampling by biopsy forceps versus mid-trimester amniocentesis: a randomized controlled trial project.

Up to now, no data are available comparing amniocentesis and chorionic villus sampling (CVS) using biopsy forceps. A series of 1313 consecutive women referred to our unit before 12 weeks of pregnancy for fetal cytogenetic analysis because of advanced maternal age, were randomized into CVS with the use of transcervical biopsy forceps or mid-trimester amniocentesis. The diagnostic success rates of the two groups were 98 per cent and 100 per cent, and a second procedure was needed in 4.1 per cent (13/314) and in 0. 3 per cent (1/358), respectively. Follow-up was achieved in 98.7 per cent of the pregnancies. Postprocedure spontaneous fetal losses, until the first week after birth, in the 672 pregnancies that completed the trial accounted for 2.2 per cent (7/314) in the CVS group and 2.8 per cent (10/358) in the amniocentesis group. Although the trial was prematurely discontinued, and therefore the sample size was smaller than initially planned, the results indicate that transcervical CVS was as safe as mid-trimester amniocentesis.

Cutting forceps in functional endoscopic sinus surgery.

Twenty years of Functional Endoscopic Sinus Surgery have brought about a large amount of innovations and a variety of instruments, all claiming to result in better endoscopic procedures and/or better postoperative outcome. An example of such an innovation is the cutting forceps, which has been claimed to result in better wound healing. However, like several other instruments, it has never been proven to be superior to conventional non-cutting forceps techniques. A prospective, randomised double-blind study in 100 consecutive patients, undergoing bilateral FESS, compared the short term clinical outcome of surgery using cutting instruments to that of non-cutting instruments. Symptoms and endoscopic findings were evaluated at four time points during the first three postoperative weeks. Both types of surgery resulted in reduction of symptoms and in endoscopically visible healing over time, but no significant difference between the two methods was found, neither in symptom relief, nor in endoscopic impression of improvement. In conclusion, endoscopic sinus surgery with cutting instruments can be considered effective in resolving sinus disease. However, these instruments do not generate a better healing process than non-cutting instruments in the first weeks postoperatively.

Intestinal obstruction from a forgotten artery forceps: a case report.

68-year-old male patient who had had two previous gall bladder operations presented with an acute abdomen. Upon investigation an Artery Forceps was seen on plain abdominal X-ray, and subsequent laparotomy showed that it entrapped a segment of the small intestine, which was gangrenous. The gangrenous loop was delivered from the forceps followed by resection and end-to-end anastomosis. The patient had an uneventful post-operative period and remained well on follow up twenty four months later.

Comparison of bipolar scissors and bipolar forceps in tonsillectomy.

Bipolar diathermy scissors tonsillectomy is a relatively new surgical technique. We conducted a prospective study of 90 patients to compare this technique with bipolar forceps tonsillectomy. We found that the use of the bipolar scissors required significantly less operating time (mean: 3.03 min less) and allowed patients to resume eating solid food more rapidly (mean: 40.35 min earlier). Bipolar scissors tonsillectomy was safe, and there were no intraoperative complications or primary hemorrhages. A postoperative follow-up telephone survey revealed that patients who underwent scissors tonsillectomy experienced no more morbidity than did the forceps group during the first 2 weeks after surgery. We conclude that bipolar scissors tonsillectomy is a safe and rapid technique that can be used successfully as an outpatient procedure.

Removal of endometrial polyps by use of grasping forceps and curettage after diagnostic hysteroscopy.

PURPOSE OF INVESTIGATION: To determine the therapeutic efficacy of the use of gall stone forceps and curettage in endometrial polyps removal, after their detection with diagnostic hysteroscopy. METHODS: From 1997 to 2001, we conducted a prospective study in 53 patients who presented at our department for menstrual disorders, infertility problems or postmenopausal bleeding and in whom endometrial polyps were detected by hysteroscopy. All patients received general anesthesia and after hysteroscopic detection of the polyps' location, their removal was attempted by use of Desjardins gall stone forceps and curettage. Immediately after the procedure, a second hysteroscopy was performed in order to detect remnants of the polyps. RESULTS: Fifty patients presented with only one polyp, two with two polyps and one with three polyps. The mean diameter of the polyps ranged from 0.5 to 3 cm. The hysteroscopic appearance of all polyps was not suggestive of malignancy. During the second hysteroscopy we found parts or whole polyps in five and two cases, respectively, accounting for a therapeutic success of 86.8%. The hospitalization time for all patients was 24 hours and occurred no intraoperative or postoperative complications. CONCLUSION: Our method seems to be safe, with low cost and sufficient therapeutic outcome and could be used in hospitals with availability of diagnostic hysteroscopy only.

[Use of Hopkins rod-lens coupled with grasping forceps sheaths for extraction of tracheobronchial foreign bodies].

OBJECTIVE: To study the clinical application of Hopkins rod-lens coupled with gasping forceps sheaths in the extraction of tracheobronchial foreign bodies. METHODS: Sixty-two patients with tracheobronchial foreign bodies were operated on with Hopkins rod-lens coupled with grasping forceps sheaths under direct telescopic view or TV watching. High frequency jet ventilation was used and BPs ECGs SaO2 were monitored in all cases. RESULTS: Sixty-two patients were all successfully operated on. The extraction was primarily successful in 90% of the cases; and secondarily successful in 7% of the cases. No death and serious complication occurred. CONCLUSION: Compared with conventional bronchoscopic foreign body extraction, this new instrument and technique make it possible for the operator to clamp and extract foreign body under direct telescopic view or TV watching. It has increased the accuracy and safety of bronchoscopic extraction of tracheobronchial foreign bodies.

Forceps-induced cracking of a single-piece acrylic foldable intraocular lens.

A case of cracking of the intraocular lens during insertion is described, a complication not previously reported with single-piece acrylic intraocular lenses. A single large crack was noticed in the center of the intraocular lens optic after the insertion of the lens with a cross-action forceps. The crack developed due to a faulty locking mechanism in the cross-action forceps, which failed to open and release the intraocular lens inside the capsular bag. However, the crack did not cause a decrease in the best-corrected visual acuity of the affected eye.

Conversion from external nasobiliary drainage to internal drainage using endoscopically available scissor forceps.

Endoscopic nasobiliary drainage may cause undue stress, such as pharyngeal discomfort. We converted external drainage to internal drainage by cutting the external drainage tube with endoscopically available scissor forceps. Endoscopic nasobiliary drainage tubes were cut in the vicinity of the papilla using scissor forceps in 4 patients. The drainage tube was successfully cut in all patients. The tube was left for short-term internal drainage in 3 patients until the operation or endoscopic treatment was performed. The remaining patient with pancreatic head cancer was followed as an outpatient and the tube stent was occluded 62 days after cutting. Although further studies using a larger number of patients are needed, our procedure is thought to be beneficial to patients undergoing endoscopic nasobiliary drainage.

[Use of the newly designed long-handled forceps for respiratory surgery].

We report on use of the newly designed long-handled forceps for respiratory surgery. The forceps have a curved-end in the same plane as its handles. This contributes to the easier clamping of vessels running horizontally in the deep fields. It is very useful not only in thoracic surgery, such as respiratory and esophageal surgery, but also in pelvic surgery.

A study of the method of the video image presentation for the manipulation of forceps.

Recently, surgical operations have sometimes been tried under laparoscopic video images using teleoperation robots or forceps manipulators. Therefore, in this paper, forceps manipulation efficiencies were evaluated when images for manipulation had some transmission delay (Experiment 1), and when the convergence point of the stereoscopic video cameras was either fixed and variable (Experiment 2). The operators' tasks in these experiments were sewing tasks which simulated telesurgery under 3-dimensional scenography. As a result of experiment 1, the operation at a 200+/-100 ms delay was kept at almost the same accuracy as that without delay. As a result of experiment 2, work accuracy was improved by using the zooming lens function; however the working time became longer. These results seemed to show the relation of a trade-off between working time and working accuracy.

En bloc endoscopic mucosal resection of a large early stage gastric cancer by combined use of an insulation-tipped diathermic knife and a grasping forceps percutaneously inserted into the gastric lumen.

A new endoscopic mucosal resection using an insulation-tipped diathermic knife (IT knife-EMR) is a promising procedure for en bloc resection of an early stage gastric cancer. However, the use of this procedure for a large lesion on the greater curvature of the gastric middle-upper body is technically difficult. With the help of a grasping forceps percutaneously inserted into the gastric lumen, which allowed traction to be applied to the lesion, a 66-year-old man with a large tumor (49mm in diameter) on the greater curvature of the gastric middle body underwent IT knife-EMR. This approach enabled easy dissection between the submucosa and the muscle layer by the IT knife under direct vision. The lesion was completely removed as a single piece. This new technique, employing IT knife-EMR in cooperation with a percutaneously inserted grasping forceps, could be a potential procedure to make original IT knife-EMR easier. This approach may enhance the utility of original IT knife-EMR for selected tumors, that is, large tumors on the greater curvature of the middle-upper body of the stomach and/or ulcerated tumors. We propose that the present approach may provide an important alternative to laparoscopic intragastric surgery.

Mandibular fracture reduction without intraoperative intermaxillary fixation: a technique using two modified reduction forceps.

This case report demonstrates a technique that is useful for precompressing mandibular fractures and obtaining anatomical reduction of the fracture edges without the use of peroperative intermaxillary fixation (IMF) in a mandibular fracture by using two modified reduction forceps. The first forcep is positioned at the inferior mandibular border and the other in the neutral zone where it is an ideal location to place a fixation plate in mandibular fractures. This technique is indicated for the anatomic reduction in mandibular fractures of the partial dentate patient.

Low-dose intrathecal morphine sulphate as sole analgesic for pain of labour in combination with elective forceps delivery. A report of 10 cases.

Preservative-free morphine sulphate (0.5 mg in 0.5 ml normal saline) was injected intrathecally as the sole analgesic in 10 primiparous patients in the first stage of labour. Elective forceps were applied under pudendal block anaesthesia to assist the second stage of labour to prevent cephalad spread during bearing down, and so reduce the side-effects of morphine sulphate. All patients reported good analgesia during the first stage of labour. There was no loss of the bearing down reflex and, except for mild peri-oral itching in 6 patients, no side-effect attributable to intrathecal morphine was noted. No side-effects of morphine sulphate were observed in any of the infants delivered. It is concluded that intrathecal morphine sulphate combined with elective forceps delivery provides a satisfactory alternative to epidural anaesthesia in those patients whose cardiovascular status demands preservation of a normal or elevated systemic vascular resistance.
