The use of a cautery for trimming exposed nylon sutures.

Ophthalmic nylon sutures (9-0 or 10-0) that become exposed postoperatively are irritating to the patient, especially if the knots are not buried, or if the sutures are not well covered by (or protrude through) the conjunctiva. Obviously, these sutures cannot be removed safely less than six to eight weeks after surgery. The symptoms may even be aggravated by trimming the suture ends, as these become more stiff and pointed when shortened. Moreover, trimming sutures can be a difficult task in some uncooperative patients.

Sterilization failures with bipolar tubal cautery.

From a consecutive series of 105 patients undergoing bipolar tubal sterilization (BPS), ten pregnancies were reported, and a tubal patency rate of 16% was found at hysterosalpingography. There were no significant clinical variables separating the BPS failure patients from those with successful sterilization. Ninety percent of the BPS failures were intrauterine, and 90% occurred within three cycles of BPS. The results of this investigation suggest that (1) BPS tubal occlusion may be associated with an increased failure (pregnancy and tubal patency) rate; (2) the majority of BPS failures are intrauterine gestations; (3) delayed fibrosis, rather than immediate tubal destruction, may be the mechanism of BPS tubal occlusion; (4) for maximum effectiveness, patients undergoing BPS should use alternative contraception for two to three cycles; and (5) surgeons employing BPS require precise training in the application of this modality of female sterilization.

Snare cautery debridement prior to Nd:YAG photoablation improves treatment efficiency of broad-based adenomas of the colorectum.

Forty-six patients who underwent piecemeal resection of large, sessile villous adenomas followed by immediate laser photoablative therapy are presented. In contrast to previously published series utilizing laser alone, prior snare resection of such lesions provides copious tissue for histologic analysis, decreases the amount of residual neoplasm requiring laser treatment, and has the potential to improve treatment efficacy.

Retrograde balloon cautery incision of ureteropelvic junction obstruction.

Retrograde balloon endopyelotomy has produced durable success rates of approximately 80% for all patients with UPJ obstruction. Patients with poor renal function, high-grade hydronephrosis, or stricture lengths of more than 2 cm fair worse, and these factors should be considered prior to balloon endopyelotomy. The debate concerning the functional significance of crossing vessels continues. However they are probably more important in terms of the risk of postoperative bleeding than in regards to overall success rates. With the use of endoluminal ultrasound, angiography, or spiral CT, patients with significant size crossing vessels can be identified preoperatively. The retrograde approach to UPJ obstruction using a cutting balloon is a quick and relatively inexpensive (shorter operative time and hospital stay, and no percutaneous nephrostomy) method for accomplishing an endopyelotomy incision. With the development of the 5-F balloon catheter and the use of a 7-F post-endopyelotomy stent, the need to stent the ureter for 7 days prior to the procedure is overcome. In this regard, the entire retrograde endopyelotomy may be performed in a one-step outpatient procedure.

Silver nitrate: histological effects of cautery on epithelial surfaces with varying contact times.

Silver nitrate is used extensively in rhinological practice for the treatment of recurrent epistaxis. There are currently no recommendations in the literature regarding the optimum application time of this chemical for effective treatment. We assessed the histological effects of silver nitrate on mucosal tissue at varying contact times and made recommendations based on our findings. Silver nitrate was applied at predetermined contact times to tonsillar mucosa, immediately before tonsillectomy in subjects undergoing routine surgery. The cauterized areas were subsequently analysed histologically. The depth of tissue penetration by the silver nitrate was measured. The means for 5, 10 and 20 s were 0.44, 0.30 and 0.38, respectively, P = 0.3. Overall, there was no deeper penetration of the tissues with contact times over 5 s. We conclude that it is not necessary to apply silver nitrate for greater than 5 s to achieve maximal tissue penetration.
