Forceps extraction of ureteral stones.

Ureteroscopy and pyeloscopy in association with ultrasonic lithotripsy for extraction of ureteral stones has, in most instances, eliminated the need for open surgical intervention. Four ureteral stones were successfully extracted by the technique described using flexible cup biopsy forceps introduced through a Teflon sheath. This method was used when basket extraction, ureteroscopy, and other forms of endoscopic stone manipulation were unsuccessful. Two ureteral stones were removed by the transurethral route, and two were removed through a percutaneous nephrostomy tract. There has been little morbidity with this procedure, and patients have returned to normal activity within several days of hospital discharge.

A simple modification of Ciaglia Blue Rhino technique for tracheostomy: using a guidewire dilating forceps for initial dilation.

OBJECTIVE: The potential difficulty in doing initial dilation in the percutaneous dilational tracheostomy (PDT) with the Ciaglia Blue Rhino (CBR) technique has been reported by others and encountered in our clinical practice. To resolve this problem, we developed a modified CBR technique by using a guidewire dilating forceps (GWDF) to facilitate initial dilation. The present before-and-after comparison study aimed to evaluate the clinical benefits of this modified CBR technique. METHODS: Consecutive 120 patients undergoing CBR technique in the pre-conversion year and 114 patients undergoing GWDF-CBR technique in the post-conversion year were enrolled for analysis. The procedure time and procedure-related complications were compared between these two groups. RESULTS: The mean procedure time with GWDF-CBR technique was 4.5+/-1.6min, significantly shorter than 5.7+/-3.0min with CBR technique (p<0.001). Only two patients in the GWDF-CBR group required prolonged procedure time (>8min), compared with 14 patients in the CBR group. Thirty three (27.5%) of 120 patients undergoing CBR technique and 15 (13.1%) of 114 patients undergoing GWDF-CBR technique had PDT-related complications (p=0.006). Most of the complications were minor and transient. Only 13 patients in the CBR group and 3 patients in the GWDF-CBR group encountered major complications (10.8% vs 2.6%, p=0.012). Regarding the high-risk patients, 21 (36.2%) of 58 patients in the CBR group and 9 (15.8%) of 57 patients in the GWDF-CBR group had PDT-related complications (p=0.011). CONCLUSIONS: Pre-dilation with a GWDF in the CBR technique helped to prevent prolonged procedure time and procedure-related complications. We suggest that the bronchoscopy-guided GWDF-CBR serves an easy-to-operate and relatively safe PDT technique for critically ill patients.

A laparoscopic bipolar cutting forceps can assist in a case of difficult vaginal hysterectomy.

A vaginal approach to hysterectomy can become challenging when visualization is limited by poor or absent uterine descent, obesity, or other factors that make an approach to the uterine pedicles difficult. When factors occur that make application or visualization of conventional vaginal instruments difficult, using an instrument designed for laparoscopic application, with its thin, elongated shape, may permit continuation of a vaginal approach. In such a case, a Gyrus bipolar laparoscopic cutting forceps was used for coagulation and transection of the uterine pedicles during a vaginal hysterectomy. This represents a way to expand on traditional techniques for completion of difficult vaginal hysterectomy, which may be used concurrently. Surgical techniques that more easily and safely permit completion of hysterectomy by the vaginal approach can improve outcomes for all.

New forceps delivery technique for coil occlusion of patent ductus arteriosus.

We remain very enthusiastic about transcatheter coil occlusion of the PDA. However, surgical ligation has been performed successfully and with relatively low risk of complications. Therefore, an alternative nonsurgical technique must demonstrate comparable success and safety. We believe that this new forceps delivery technique has significant advantages over previously reported PDA coil occlusion techniques and should warrant further clinical investigation.

The guide wire dilating forceps technique of percutaneous tracheostomy.

BACKGROUND: Prospective evaluation of the percutaneous tracheostomy by the guide wire dilating forceps (GWDF) technique. METHODS: In 50 selected patients percutaneous tracheostomy with fiberscopic control was performed and evaluated. RESULTS: Most percutaneous tracheostomies were performed without any adverse effect. No life-threatening complications or deaths were related to the procedure. The procedure was successful in 49 of 50 patients (98%). In 1 patient the procedure was converted to an open tracheostomy because significant bleeding occurred. Five perioperative complications, including this significant bleeding and four minor complications, occurred in 50 patients (10%). Early complications occurred in 6 of 48 patients (13%), including one significant bleeding and five minor complications. A subglottic stenosis occurred in 2 of 36 successfully decannulated patients (6%). In one case this was certainly due to prolonged endotracheal intubation. CONCLUSIONS: The GWDF technique is a safe and efficient bedside alternative to open tracheostomy. Fiberscopic control is recommended to increase the safety of the procedure. Although studies of late complications are necessary, it appears to be justifiable to consider percutaneous tracheostomy for patients who require tracheostomy.

Follow-up of hot biopsy forceps treatment of diminutive colonic polyps.

Although the hot biopsy technique is widely used to treat diminutive colon polyps, there is concern over its efficacy and safety. Our study involved 39 patients undergoing routine colonoscopy in whom 62 diminutive polyps were found in the rectosigmoid. These lesions were treated with hot biopsy forceps in the standard manner. Flexible sigmoidoscopy was repeated 1 and 2 weeks later with the original treatment sites being identified. Eleven of the 62 sites (17%) revealed persistent viable polyp remnants, indicating incomplete treatment. In terms of safety, there were no clinical complications in this small study and most post-biopsy ulcers were healed by 2 weeks. This study shows that the hot biopsy technique may be unreliable in eradicating diminutive colon polyps.

Endoscopic retrograde forceps biopsy and brush cytology of biliary strictures: a prospective study.

BACKGROUND: Nonsurgical pathologic confirmation of malignant bile duct strictures is desirable for defining subsequent treatment and prognosis. Endoscopic retrograde cholangiopancreatography is frequently performed in patients suspected of having pancreaticobiliary obstruction, but there exists no standardized method for defining the nature of obstructing lesions by ERCP. METHODS: We prospectively evaluated the yields of endoscopic retrograde brush cytology and biopsy for the diagnosis of malignant bile duct strictures. Fluoroscopically guided endobiliary biopsy and brush cytology (52) or cytology alone (42) were performed during endoscopic retrograde cholangiopancreatography in 94 consecutive patients, 64 with malignant strictures and 30 with benign strictures. A single cytopathologist classified the results of these studies as positive or negative for malignancy. RESULTS: The sensitivities of the two procedures were identical (53%) and the gain achieved by combining the two techniques (61%) was small. Specificity proved excellent for both methods. One major complication that occurred was perforation of the common hepatic duct with leakage of bile, which was managed by surgical oversewing. This complication was ascribed to biopsy and untimely removal of the nasobiliary drain by the patient herself. CONCLUSIONS: This study indicates that endoscopic retrograde brush cytology alone may be sufficient in daily practice, at least in centers that have access to experienced cytopathologists. We recommend use of forceps biopsy in selected cases where brush cytology is negative.

A new specifically designed forceps for chest drain insertion.

Insertion of a chest drain can be associated with serious complications. It is recommended that the drain is inserted with blunt dissection through the chest wall but there is no specific instrument to aid this task. We describe a new reusable forceps that has been designed specifically to facilitate the insertion of chest drains.A feasibility study of its use in patients who required a chest drain as part of elective cardiothoracic operations was undertaken. The primary end-point was successful and accurate placement of the drain. The operators also completed a questionnaire rating defined aspects of the procedure. The new instrument was used to insert the chest drain in 30 patients (19 male, 11 female; median age 61.5 years (range 16-81 years)). The drain was inserted successfully without the trocar in all cases and there were no complications. Use of the instrument rated as significantly easier relative to experience of previous techniques in all specified aspects. The new device can be used to insert intercostal chest drains safely and efficiently without using the trocar or any other instrument.

Microsuture-tying forceps with attached scissors for bypass surgery.

BACKGROUND: Bypass surgery requires the shortest temporary occlusion time of a recipient artery during anastomosis. For this purpose, we have devised a microforceps with attached scissors that makes it possible to perform the multiple steps involved in anastomosis without exchanging instruments. This microforceps avoids having to exchange instruments twice in one suturing, such as that between a microsuture-tying forceps or a microneedle holder and microscissors in conventional methods. METHODS: The instrument is made of stainless steel and is 15.5 cm long. Using this microforceps with scissors, we can suture, tie, and cut a ligature fluently for consecutive sutures without exchanging instruments. The mean time during one suturing was compared between two patient groups treated by conventional method and with use of this instrument. RESULTS: This instrument was used for 34 patients with ischemic cerebrovascular disease (including three who needed deep-site anastomoses) and allowed us to perform superficial temporal artery-middle cerebral artery (STA-MCA) anastomoses uneventfully. This instrument saved 15.2 s in the mean time during one suturing. CONCLUSIONS: Although it is of paramount importance to practice tying sutures well, this new instrument removes the need to exchange conventional instruments, and we believe it will save time and, therefore, decrease complications during bypass surgery.

Forceps insertion with incisional anesthesia for Sensar intraocular lenses.

This technique to prevent self-adherence of the Sensar acrylic intraocular lens (IOL) optic during forceps insertion with wound stretch includes modifications to the 3-and-9 insertion technique to prevent difficulties that may be encountered with this phenomenon. To decrease patient sensation during IOL insertion and thus improve surgeon control, the corneal tunnel incision is directly anesthetized.

One-step forceps for capsulorhexis.

There are several popular methods for creating a continuous-tear capsulotomy, or capsulorhexis, which usually involve several instruments and steps. This report describes a new forceps for capsulorhexis that can be used to open the capsule and complete the circular tear in one step. Its unique features are its small size, shortened length, thin, rounded blades with cystotome-type tips for opening the capsule, and round handles for manipulation ease.

Paired parallel locking forceps.

We describe an instrument used to prevent contact between an antimetabolite and the conjunctiva-Tenon's wound edge in filtering surgery. Paired parallel locking forceps were used to keep the everted conjunctival-Tenon's wound edge from touching the antimetabolite sponge during limbal-based filtering surgery while enabling manipulation of the antimetabolite sponge. This allows the surgeon to more easily avoid the conjunctival edge, making antimetabolite touch easier and safer.
