Minimally invasive transrotator cuff approach for arthroscopic stabilization of the posterosuperior glenoid labrum.

We describe a novel technique for repair of the superior glenoid labrum posterior to the biceps anchor. This approach optimizes access for fixation of the superior and posterosuperior labrum, but involves significantly less trauma to the rotator cuff and subacromial space compared with previously described transrotator cuff methods. We suspect that the relative lack of trauma to the rotator cuff and subacromial space accounts for the superior clinical scores and lower incidence of postoperative impingement symptoms with this technique compared with previously reported transrotator cuff methods.

How to use cuff suture instruments: the concept of "concave in and concave out".

Arthroscopic reconstructive surgery of the shoulder is extremely demanding. The advent of suture anchors and knot-tying instruments has greatly facilitated its development. Knowledge of the anatomy and surgical principles alone is not enough. Familiarity with specific instruments is also important. We describe our experience with the Elite Cuff Stitch Suture Relay (Smith & Nephew, London, U.K.). We describe a new concept on how to use this suture passer or similar instrument. We advocate this new concept of "concave in and concave out."

Transtibial tubercle fixation without hardware for anterior cruciate ligament and posterior cruciate ligament reconstruction: A new technique.

Tibial fixation with implants for both anterior and posterior cruciate ligament reconstructions (ACLR and PCLR) can be associated with a wide variety of problems. Common problems encountered include graft-tunnel mismatch when using grafts with bone blocks, graft damage or poor graft fixation using metal or absorbable implants, painful retained hardware requiring removal, and hardware interference during revision surgery. A new technique is presented using transosseous graft suture passage across the tibial tubercle followed by knot tying over a bone bridge. The technique provides a quick, simple, safe, and reproducible alternative for primary or supplemental tibial graft fixation without hardware in ACLR and PCLR.

Arthroscopic humeral avulsion of the glenohumeral ligaments (HAGL) repair.

Humeral avulsion of the glenohumeral ligaments (HAGL lesion) is one of the pathologic lesions that occurs secondary to anterior glenohumeral instability. Although HAGL lesions occur less commonly than Bankart lesions in cases of anterior instability, it is necessary to understand this pathology and to make the necessary repair. An all-arthroscopic technique using suture anchors can be used to repair HAGL lesions, but it is a difficult and demanding technique. To facilitate this type of repair, the surgeon must be: (1) comfortable with both the 30 degrees and 70 degrees arthroscopes, (2) able to establish and use the 5-o'clock portal, (3) able to abduct and externally rotate the arm, and (4) able to ensure secure fixation of the glenohumeral ligaments to bone through adequate knot and loop security.

Laparoscopic nephron sparing surgery: evolution in a decade.

OBJECTIVE: To present our experience with laparoscopic nephron sparing surgery (NSS) over a decade. METHODS: Seventy-eight patients underwent NSS since 1994. Two techniques were used-partial nephrectomy without ischemia (group 1) in 29 patients, and with ischemia (group 2) which was in cold or warm ischemia in 24 and 25 patients respectively. The mean tumour size was 1.97 and 2.2 cm in groups 1 and 2 respectively. Renal reconstruction evolved in our hands during this period. We changed many technical details and now we depend more on clips for securing the sutures rather than free hand knotting. RESULTS: The mean operative time was 162 and 216 minutes in groups 1 and 2 respectively. Mean ischemia time for patients with cold and warm ischemia was 44.9 and 33.8 minutes respectively. 3 patients in group 2 were converted to open surgery. Mean blood loss was 254 and 212 ml for group 1 and 2 respectively with two major bleedings in group 2. Minor intra-operative complication occurred in 3 patients, and major and minor postoperative complication in 15 patients. At a mean follow-up of 23.9 and 12.2 months for groups 1 and 2 respectively there was no recurrence. CONCLUSION: Warm and cold ischemia have widened the indications for laparoscopic NSS to more complex tumours and allow renal reconstruction with acceptable complication rate.

Aortic root replacement with human tissue valves in aortic valve endocarditis.

OBJECTIVE: Aortic allograft and pulmonary autograft aortic root replacement in native and prosthetic aortic valve endocarditis are evaluated and risk factors for hospital death are assessed by univariate risk factor analysis. METHODS: From April 1989 to May 1996, 59 patients with aortic valve endocarditis (27 native; 32 prosthetic) underwent aortic root replacement with a human tissue valve. Mean age was 53.4 +/- 12.3 years; 46 patients (78%) were male. The mean preoperative NYHA functional class was 3.4. The predominant infective organisms were streptococci (30%) in the native valve group and staphylococci (30%) in the prosthetic valve group. In native valve endocarditis, valve destruction (32%) was the predominant finding. Abscesses, either annular (29%) or subannular (36%) and valve dehiscence (36%) were the most common findings in patients with prosthetic valve endocarditis. Partial or total ventriculo-aortic discontinuity (20%) and aortico-mitral discontinuity (27%) were other important operative observations. A cryopreserved allograft was used in 53 patients (89.5%), the pulmonary autograft (Ross procedure) in 5 patients (8.5%), and a fresh antibiotic sterilized allograft root in one patient (2%). Mean aortic cross-clamp time was 131 +/- 32 min. In active native and prosthetic valve endocarditis, intravenous antibiotics were continued for at least 6 weeks, monitored by serial CRP measurements. RESULTS: Hospital mortality was 8.5% (n = 5; 70% CL: 4.9-12.1%). Univariate risk factors for hospital mortality were age (P = 0.001), preoperative New York Heart Association functional class (P = 0.001), pre- (P = 0.001) and postoperative (P = 0.001) renal insufficiency. Major complications were allograft failure (n = 1; 2%), technical failure (n = 1; 2%) and false aneurysm formation at the proximal suture line (n = 1; 2%). Follow-up was complete, mean 33.1 +/- 20.1 months. Two late deaths occurred. Actuarial five year survival was 88.8% (70% CL: 80.0-97.5%); actuarial five year freedom from recurrent endocarditis was 98.1% (70% CL: 94.5-100%). CONCLUSION: Allograft aortic root replacement is a valuable technique in the life threatening situations both of native and prosthetic aortic valve endocarditis with involvement of the annular and peri-annular region.

Arthroscopic anterior cruciate ligament reconstruction with quadriceps tendon composite autograft.

At present, no single graft option clearly outperforms another. Autografts (patellar tendon, hamstring) and allografts (Achilles tendon, patellar tendon) are the grafts most often used. However, each grafts has advantages and disadvantages. Quadriceps tendon graft for anterior cruciate ligament reconstruction is not new, but an alternative composite graft is introduced here that consists of quadriceps tendon-patellar bone and bone obtained from a coring reamer used to create the tibial tunnel. This composite graft retains reduced morbidity while allowing the secure bone-to-bone fixation associated with bone-patellar tendon-bone graft.

Transumbilical laparoscopic cholecystectomy utilizes no incisions outside the umbilicus.

Laparoscopic cholecystectomy has become the gold standard in the care of patients with cholelithiasis. A standard laparoscopic cholecystectomy employs three trocar incisions outside the umbilicus, which are a source of potential wound complications and an undesirable cosmetic outcome. We describe here a modification of the laparoscopic cholecystectomy which utilizes two transumbilical trocars and two transabdominal gallbladder stay sutures and does not require abdominal wall incisions outside the umbilicus. When technically feasible, this technique results in superior cosmesis and may reduce postoperative wound complications.

End-to-side vascular anastomosis: a study of technical considerations in the rat.

A study of technical problems in the performance of microvascular anastomosis has been carried out in the rat. A comparison of two types of suture material suggested that handling characteristics had a significant effect on the time taken to complete the anastomosis, and on the accuracy of apposition of the vessel walls. Technical difficulties encountered intraoperatively proved predictive of subsequent compromise of the lumen, shown angiographically and histologically. The optimum conditions are discussed, and it is argued that postoperative antithrombotic medication is indicated when technical problems are encountered.

Preliminary experience in ileal neobladder reconstruction.

In the treatment of transitional cell carcinoma of the bladder, the recent trend is towards radiation or chemotherapy which can be either regional or systemic. There have also been good results with giving Mitomycin or Bacillus Calmette Guerin instillation into the bladder for superficial tumours. There are occasions where patients present with large bulky tumours which cannot be controlled by endoscopic measures, invasion involving multiple sites and carcinoma in-situ which progresses to invasion. In these occasions, we have to resort to surgical clearance of the tumour. If it is possible, all patients would not like to wear a urinary bag for the rest of their lives. A bladder replacement if ever possible is always welcomed because the patient can pass urine from the natural passage. Due to the magnitude of a radical cystectomy and status of the urethra, it is not always technically possible to reconstruct the bladder. With improvement of operative techniques and suture materials, there has been a recent development of a method of bladder reconstruction that uses an ileal pouch. We report our early experience with this operation.

[Primary surgical treatment of amputated fingers and indications for digital replantation].

The amputation of a single finger, or its part, or more fingers results in functional and esthetic changes in the patient's life. Until 1965 when the first thumb ever was replanted, the treatment of amputated digits had been limited by technical facilities of the medical science. Since 1970s, the development of fine suture materials, microsurgical instruments and the operating microscope has made it possible that replantations have become routine procedures in hand surgery. Both surgical procedures and indication schemes have also evolved. The primary surgical treatment has been standardized to involve the wrapping of amputated parts in dressing material saturated with isotonic solution and cooling at 4 to 10 degrees C during transport. The first enthusiasm for replantation of everything that had been amputated was replaced, owing to long-term post-operative results, by a more selective approach. Even an absolute indication for digital replantation, such as amputation of a thumb, two or more fingers, amputation in the palm and all amputations in children, must be put aside when life-threatening injuries or serious diseases are present. The benefit of replantation should always outweigh the trauma of any operative procedure because this must not harm the patient.

[Mammary-coronary artery anastomosis in current cardiological surgery].

The article generalizes the experience in the treatment of 193 patients with ischemic heart disease by operation for direct mammary-coronary anastomosis (MCA). The author discusses technical aspects of the operation, in particular the use of vacuum vessel suturing apparatuses for its accomplishment, problems of extracorporeal circulation, and the long-term results. It is concluded that MCA is one of the most effective, reliable, and economical operations and should be used more widely in the management of ischemic heart disease.

Double stapling technique for low colorectal anastomoses after anterior resection for rectal cancer.

A group of 26 patients submitted to anterior colorectal resections for carcinoma is reported: all of the anastomoses were performed using the so-called "Double Stapling Technique" (DST), first introduced by Knight and Griffen in 1980. The technical results are discussed, in the light of recent reports. "DST" offers clear advantages, over both traditional hand-stitched and end-to-end stapled anastomosis. This procedure is considered cost-effective and time-saving and offers lower intra-operative risks. It permits optimal sterility of the operative field and lower risk of neoplastic spreading. Furthermore it eliminates some technical problems such as the preparation of the distal purse-string suture and the inequality between the two intestinal stumps to be anastomosed.
