[Ureterosigmoidostomy detubularized with surgical staplers: C.F.C. (Original technique)].

Description of our modification of the detubulized ureterosigmoidostomy surgical technique (Castiñeiras-Ferragut-Camacho). In an attempt to shorten the surgery time, we used for these changes absorbable mechanical sutures (Poli Gia and T.A.). This paper analyzes the technical details of interest as well as the anatomicosurgical considerations that should be known prior to carry out this type of by-pass. The anatomicophysiological principles on which our developments are based are those referred by N.G. Kock15 and used by R. Hohenfellner and R. Fisch14, when they described the detubulized ureterosigmoidostomy performed manually. We believe that both surgical procedures, R. Hohenfellner & R. Fisch14 and ours (detubulized ureterosigmoidostomy, C.F.C.), are suitable alternatives to conventional ureterosigmoidostomy.

[Prosthetic repair of inguino-crural hernia using Rives technique].

The authors report their experience with Rives procedure, a prosthetic repair of groin hernias using preperitoneal sutured mesh by parainguinal access. This operation is not technically easy to perform and is usually done out of necessity in cases with higher risk of recurrence because of systemic factors of chronic abdominal high pressure and/or of local factors of risk, when there are contraindications to operations like Stoppa procedure. Our series report 38 patients operated upon on 5 years, with incidence of 5.8% overall hernias repaired in the same period. 33 are males, 5 females, with average age of 60.5 years. Mean time required for the operation is 94 minutes (range 55'-130'). About postoperative complications we complain of one testicular atrophy, but none infections. Follow-up range is 9-50 months (average 23.2 months) for 30 patients operated more than one year ago. All but one were revisited after almost 12 months. No recurrences were detected.

Suture holes in anterior cruciate ligament bone-patellar tendon-bone grafts.

Anterior cruciate ligament reconstruction with a bone-patellar tendon-bone graft is a common and technically demanding surgery. Traditional preparation of the femoral bone plug includes 2 transcortical holes with leading sutures to pull the graft into the knee. The pull of the sutures and patellar tendon are not colinear with the bone plug and femoral socket. The bone plug tilts, thus impairing passage into the femoral socket. A new preparation technique was devised that, by changing the location of the suture holes, decreases graft tilting and improves passage. In our study, traditional and new techniques of femoral bone plug preparation were investigated by force diagramming and then graft modeling. Bone plug tilting was caused by the trailing pull of the patellar tendon eccentric to the plug and socket. By preparing the femoral bone plug with a diametric, transverse trailing suture hole, the plug became colinear with the femoral socket for easier passage. The new technique was then surgically implemented with straighter and faster graft passage.

[Mechanical trans-sutural colorectal anastomosis in the treatment of cancers of the rectum. Apropos of 70 cases].

The reduction in the acceptable length of distal margin below the tumor makes low anterior resection more suitable for rectal cancers. The technical difficulties of low anastomosis are reduced by performing stapled colorectal anastomosis through the suture. Seventy patients were submitted to this procedure. There was no operative mortality, while the reported morbidity was 14%. Sixteen patients underwent preoperative radiotherapy of 30 Gy without any subsequent leakage. This technique is discussed in relation to the hand-sewn colo-anal anastomosis.

Percutaneous arterial closure in severely scarred groins: a technical note.

We present a new method to enable the insertion of percutaneous suturing devices in severely scarred groins, using a peel-away sheath. This sheath stabilizes the percutaneous tract for the suturing device. It may help to salvage closure procedures, which would otherwise have to be aborted due to insufficient stiffness of the device shaft.

[The use of microsurgery technics in surgery of the stomach and intestines].

The one-layer intestinal suture, using microsurgical technique, was done in experiment on 68 laboratory animals (157 small intestinal and colonic anastomoses were formed in total). Maximally favourable conditions, promoting the primary closure of the anastomoses healed were established. The proposed anastomosing method efficacy was confirmed by favourable results of operative interventions, performed in 108 patients with different surgical diseases in the planned and urgent order.

Robotic ocular surgery.

BACKGROUND: Bimanual, three-dimensional robotic surgery has proved valuable for a variety of surgical procedures. AIMS: To examine the use of a commercially available surgical robot for ocular microsurgery. METHODS: Using a da Vinci surgical robot, ocular microsurgery was performed with repair of a corneal laceration in a porcine model. The experiments were performed on harvested porcine eyes placed in an anatomical position using a foam head on a standard operating room table. A video scope and two, 360 degrees -rotating, 8-mm, wrested-end effector instruments were placed over the eye with three robotic arms. The surgeon performed the actual procedures while positioned at a robotic system console that was located across the operating room suite. Each surgeon placed three 10-0 sutures, and this was documented with still and video photography. RESULTS: Ocular microsurgery was successfully performed using the da Vinci surgical robot. The robotic system provided excellent visualisation, as well as controlled and delicate placement of the sutures at the corneal level. CONCLUSIONS: Robotic ocular microsurgery is technically feasible in the porcine model and warrants consideration for evaluation in controlled human trials to deploy functioning remote surgical centres in areas without access to state-of-the-art surgical skill and technology.

[Anastomotic suture incompetence after transperitoneal resection of the rectum].

Sphincter saving operations were made in 68.1% of 276 radical operations on the rectum, 85.6% of them being transperitoneal resections. The advantages of this operation are: less traumaticity, blood loss and postoperative lethality as well as saved function of the sphincter apparatus. Incompetence of the sigmorectal anastomosis sutures developed in 29 (18.6%) patients. The dependence of frequency of this complication on the sex and age of the patients, on the character of the disease and localization of tumor, on using suturing apparatuses, radiation treatment and unloading colostomy was studied. The distinctions found proved to be unreliable. Direct causes of the development of the complication are thought by the author to be technical defects of the surgery, disturbed blood supply and regenerative abilities of the sutured end of the gut. Recommendations are given how to prevent the development of the complication and of its more severe consequences.

[Modified Komeda-David operation for postinfarction ventricular septal perforation].

The infarct exclusion technique with a xeno-pericardial patch which Komeda and associates firstly reported in 1990 is one of the best procedure to close ventricular septal perforation. A large patch can protect the perforation and the surrounding weak tissue from the internal left ventricular pressure. However, suturing this large patch to the left ventricular wall through the small incision is not technically easy because of the patch design in the ventricle. We modified the design of the patch. This round shaped bovine pericardial patch was sutured continuously to the left ventricular wall. Then, excessive part of the patch was trimmed to make a corn shape. Finally, the corn shaped patch fit the left ventricular wall naturally.

Visual clues in minimally invasive surgery: use of 2-D versus 6-D enhanced performance of complex minimally invasive complex skills.

UNLABELLED: In the recent past, we used two 2-D videoscopes to obtain both a close detailed view and simultaneously a panoramic view to improve the efficient and safe access for instruments into the microscopic working field by way of the benefits of the panoramic view. This bi-modal visual set of clues allows for (1) insertion of suture, (2) cutting of suture with scissors (3) retraction of tissue, and (4) removal of suture and needle. During these experiences, we observed the benefits accrued to the surgeon by allowing the focusing of his/her attention on the work (technical skills) without diffusing energy to other activities. Similarly, when training surgeons to perform micro-anastomoses, and while working to improve performance in micro-anastomoses, we hypothesize that two or more videoscopic views of the 3-dimensional working space would provided added visual information to the surgeon during the microscopic work. To examine this hypothesis, we have used a non-animate model, in the performance of complex skills in videoscopic surgery. METHODS: Inanimate videoscopic models for suturing and tying (24 studies) were used in this study. The technical skill studied was the sophisticated skill of suturing. The speed and accuracy of Free-Handed suturing and tying was determined in these studies. They were compared using a single 2-D system verses three videoscopic views reconstructing a 3-D effect. RESULTS: In each of these models, the delineation of multiple views allowed greater detailed 3-dimensional information for the surgeon. The sutures were placed faster, more accurately, and with fewer false motions. These data allow us to conclude the use of multiple high-resolution 2-D views will improve accuracy and efficiency in the performance of delicate and precise skills in videoscopic surgery.

[Formation of an esophageal-intestinal anastomosis in stomach cancer].

It is suggested to contruct entero-entero, and entero-esophageal anastomoses by means of the SPTU-suturing apparatus with detachable heads through the lumen of the anastomosed jejunum. The technic in use prevents the development of reflux-esophagitis, thus greatly accelerating the accomplishment of the most painstaking stage of the operation--constructing of the anastomoses, and reduced the incidence of suture incompetency of entero-esophageal anastomosis.

Colorectal anastomosis by transanal end-to-end stapling.

In 26 patients end-to-end colorectal anastomosis was attempted using a transanal stapling instrument. The anastomosis was successful in 19 patients. Permanent colostomy would have been the only alternative treatment in 12 patients. In five patients, other sphincter-saving methods of anastomosis would have been technically feasible but more difficult and hazardous. In the remaining two patients standard sutures or side-to-side stapling could have been used equally easily. The technique of anastomosis, the complications and the functional results are reviewed. The authors conclude that transanal end-to-end stapled anastomosis is an important technical advance in colorectal surgery.

Otoplasty.

When multiple techniques are described to address a single condition, it is axiomatic that no single technique is ideal. Using mattress sutures to create an antihelical fold when one is absent provides benefits that outweigh the risks of this technique. It is a technique that can be learned quickly and mastered with experience. Goode's successful revision otoplasties with mattress sutures suggest that excessively springy ears are not the reason for failure. His results suggest that technical errors may be responsible for the lack of success at the initial procedure. No technique is without complications or limitations, and this technique is no exception. Conservative resection of the concha just medial to the lateral edge with reapproximation to the cauda helicis offers a quick, reliable approach to prominent conchal bowls. Prominence of the lobule was not described in detail. The lobule should, of course, be corrected if it contributes to the ear deformity. Chosen operative techniques should be adaptable to various deformities, and it is preferable, therefore, that the surgeon is comfortable with multiple techniques. The first step in this level of comfort is to acquire a detailed knowledge of ear anatomy. Only by having a firm grasp of the normal can the abnormal be understood precisely. Although a sound technical platform is required to achieve superior results, excellence is achieved only by a thorough, detailed preoperative analysis. A combination of mattress sutures to address the antihelix and lateral resection of the conchal bowl produces excellent results in most cases. Applying a rote technique to all deformities, however, is ineffective and will compromise results. Superior outcomes can be attained only with command of a combination of acute diagnostic skills, knowledge of various surgical techniques, and the ability to execute those techniques.

The pretrained novice: using simulation-based training to improve learning in the operating room.

Enabling trainees to acquire advanced technical skills before they begin the operating room experience benefits both trainee and patient. Whether medical students who had received exclusively simulation-based training could perform laparoscopic suturing and knot-tying as well as senior surgery residents was determined. Simulators were used to train 11 fourth-year medical students with no previous suturing experience to perform intracorporeal suturing and to successfully tie a free-hand intracorporeal knot. Students' skills were assessed by the performance of the fundal suturing portion of a Nissen fundoplication in a porcine model. Their operative performance was evaluated for time, needle manipulations, and total errors. Results were compared to those of 11 senior-level surgery residents performing the same task. The study concluded that trainees could learn advanced technical skills such as laparoscopic suturing and knot tying by using simulation exclusively. The trainees and senior level surgery residents had a similar number of needle manipulations.

Utility of fully buried horizontal mattress sutures.

BACKGROUND: Deep absorbable stitches should provide a firm closure, hemostasis, and good wound-edge eversion, but this is not always achieved with standard techniques. OBJECTIVE: We sought to investigate alternative techniques that can rapidly and reliably achieve these results. METHODS: We evaluated the fully buried horizontal mattress suture. We compared this technique with the previously described fully buried vertical mattress, partially buried mattresses, and standard reticular dermal and subcutaneous sutures. RESULTS: The fully buried horizontal mattress can provide excellent wound-edge approximation and eversion. It is particularly useful for shallow defects and narrow spaces where a deep stitch is required but technically difficult to insert. Overall, this method offers excellent final cosmesis, and individual sutures can be quickly and reproducibly placed with minimal practice. For very deep defects that require dead-space closure, the fully buried vertical mattress may be preferable. CONCLUSIONS: The buried horizontal mattress suture has wide applicability as the buried stitch in a bilayer repair.

Techniques in eyelid wound closure.

While one of the most basic techniques in eyelid surgery is the repair of an eyelid defect that involves the margin, many eyelid defects are still poorly repaired; and much confusion still exists in this area. Based upon sound anatomic and surgical principles, we suggest several modifications of classically described techniques: (1) The greyline suture is replaced by a tarsal suture through the meibomian gland orifices to provide a stronger closure and better alignment. (2) All tension of closure is supported by the deep tarsal sutures rather than by the margin sutures to avoid notch formation or unsightly scars. (3) A two-layered closure where orbicularis and tarsus is closed in a single layer is technically easier and gives results comparable to the classically taught three-layered closure. Conjunctival sutures in the tarsal portion of the eyelid are unnecessary and frequently cause corneal irritation. (4) When lid resection is performed, a pentagonal excision rather than a "V" or wedge resection should be used to minimize tension on the margin when closed. We present in an illustrated step-by-step fashion our preferred technique which gives consistently good results.

[External drainage and suture of the bile ducts following choledochotomy].

The authors report their experience with the use of a T-shape drainage in 258 choledochotomies, accomplished in 248 patients, and suturing of the common bile duct in 77 patients. The technic of preparation of a T-shape drainage, its fixation in the common bile duct and the postoperative management of patients with such drainages are described. The complications developed while using a T-shape drainage are analysed. Late sequelae of application of the drainage were taken into account after 219 operations, whereas in 163 patients intravenous cholangiography was performed after such drainage of bile ducts, the terms being longer than 3 years in 140 cases.

Mechanical suture methods in thoracic and abdominal surgery.

Mechanical suturing procedures on the bowel, lung, bronchi and pulmonary vessels have been used on 264 occasions in 180 thoracic and abdominal operations. The instruments proved simple to use and produced reliable good quality closures, for the most part without manual reinforcement. There were 2 technical failures, one ending fatally, after colo-colostomy. Two minor postoperative suture leaks were encountered in 122 operations on the alimentary tract, but no leakage or other problem has arisen in 58 pulmonary cases. The staple-suturing methods described are safe and straightforward, and it is believed that they represent a significant advance in the techniques of thoracic and abdominal surgery, which can usefully be applied in many situations.
