[New surgical technique for anterior cervical fusion; surgical technique for anterior cervical fusion utilizing autogenous bone graft from the cervical vertebrae].

Since April, 1990, the authors have been reporting a surgical technique for anterior cervical fusion utilizing autogenous bone graft from the cervical vertebrae. This series included 53 patients (40 males and 13 females). The age ranged from 24 to 72 years with a mean of 49 years. There were 42 cases of cervical disc disease, and 11 cases of cervical disc disease with ossification of the posterior longitudinal ligament (OPLL). The patient was out of bed within two days and treated in a soft collar for 3 months. In all patients, the symptoms improved postoperatively. Postoperative X-ray showed slight anterior angulation deformity in 3 out of 53 cases (6%). The advantages of our surgical technique are as follows: 1) There are no problems related to the iliac donor site 2) The removal of posterior spur and localized OPLL is safely and easily performed.

A new one-stage surgical technique for postlaryngectomy speech.

A new one-stage surgical technique for the postlaryngectomy speech applied to the 17 patients and its results are described herein. The essential part of this technique consists of the construction of a tracheo-esophageal shunt using only the remainder of the trachea obtained at the time of laryngectomy to reestablish an air communication between the trachea and the gullet. Fourteen patients of the 17 patients thus operated upon developed conversational abilities equivalent to the normal subject, except that they use a finger during the speech for the occlusion of the tracheal opening. This technique can be applied to almost all candidates for total laryngectomy with or without neck dissection. The initial speech was developed in 25 days after operation in average. The inflow of the salivas and/or fluids into trachea is not problematic in these patients. It has been well known that an air communication reestablished between the natural air way and the gullet could reproduce a vocal function after total laryngectomy [5]. Despite very few surgical techniques for this purpose have been described and applied clinically, although a tremendous effort has been made for the complete removal of the malignancy and the avoidance of recurrence up to the present [1--4, 6]. A new surgical method for achieving a tracheo-esophageal shunt for the postoperative vocal function is described herein.

A standardized surgical technique to obtain a stable and reproducible chronic renal failure model in dogs.

The remnant kidney, a model of chronic renal failure in animals, can be obtained by two techniques: either surgical removal of tissue of one kidney, combined with contralateral nephrectomy or inducing necrosis of kidney tissue by ligation of branches of the renal artery of one kidney combined with contralateral nephrectomy. In the literature, most reports concern the ligation technique. The technique is safe and simple but the results in dogs are unpredictable. In this paper, both techniques were compared. We could demonstrate that the unpredictable result of the ligation technique is due to the formation of collateral vessels bypassing the ligated branches and to the inconstant ramification pattern of the renal artery. In this study, a standardized technique consisting of the resection of 16-18 g of tissue of one beagle kidney and removal of the other one is described. This method results in a stable chronic renal failure until the dogs are sacrificed at 9-12 months.

Comparing ridge resorption with various surgical techniques in immediate dentures.

The three surgical techniques of simple tooth extraction and labial plate and intraseptal alveoloplasty were compared. The results were confirmed by statistical analysis. The conclusion of this study clearly indicated that simple tooth extraction is the best surgical approach to be followed to preserve as much of the residual alveolar ridge as possible.

New surgical technique for type B aortic interruption.

Restoring continuity of the aortic arch in aortic interruption continues to be a problem in terms of both surgical technique and long-term results. We report here a surgical technique using the left subclavian artery along with an aberrant right subclavian artery to form a conduit in a patient with type B interruption, to reestablish aortic continuity.

Quality control of surgical technique in a multicenter, prospective, randomized, controlled study on the surgical treatment of gastric cancer.

To evaluate the effect of lymph node dissection on gastric cancer patients operated upon with curative intent, we are carrying out a multicenter, prospective, randomized, controlled study in the Netherlands. The trial compares conventional gastrectomy to gastrectomy with extended lymph node dissection. In the first four months, a Japanese supervisor attended all the extended surgery and instructed many Dutch surgeons, including the eight consulting surgeons; since then, all extended gastrectomies have been attended by one of the consulting surgeons. The study coordinator attended all conventional cases. This assured that the quality of the extended surgery was as good as the Japanese standard, of which excellent results have been reported. To achieve this quality control, randomization before surgery was obligatory for practical reasons. Curability assessment at laparotomy, however, is done quite objectively with histological proof, except for the judgement of irresectability. Although this has resulted in many non-curative cases being randomized but subsequently not given the allocated surgery, the sample size should be sufficient to allow analysis according to randomization or the initial "intention to treat." This is the first protocol for a multicenter trial in surgical oncology to have such excellent surgical quality control and to assure a quality as high as that in the original report with uniformity in the level of technique. In studies comparing surgical techniques, it is vital that attention should be given to surgical quality control, otherwise survival rates may show little improvement and fail to make any impact on surgical practice.

Brain abscess and subdural empyema. Factors influencing mortality and results of various surgical techniques.

The authors review the results of various surgical techniques in relation to mortality and morbidity in 100 consecutive cases of brain abscess and subdural empyema. The mortality rate is the same with total excision and fractional drainage of brain abscesses, although in acute and subacute cases slight differences between both techniques are seen. In terms of morbidity, fractional drainage appears to be more favourable than total excision. The authors believe that factors other than surgical procedure influence mortality in cases of brain abscess and subdural empyema. These factors are defined in detail.

Number and shape of tears in aphakic retinal detachment: its relationship with different surgical techniques of cataract extraction.

An analysis is made of retinal detachments which occurred in patients operated upon for cataract with different surgical techniques, as well as the degree of operating experience of the surgeons. The main clinical features of the detachments are recorded such as number, shape, localization of retinal tears, type and extension. The different surgical techniques are explained and a statistical comparison of the incidence of detachments is set up.

Stenotic conditions of the lumbar spinal canal: changes in surgical techniques in the management of low back disability.

The diagnostic recognition of acquired stenotic conditions in the lumbar spinal canal occurring from the fifth to the eighth decades of life had led to a significant change in surgical techniques during the last ten years. This communication presents a comparison of surgical techniques used by the author in two consecutive series of patients operated for low back, lumbosciatic, and spondylotic caudal disability syndromes during the period 1965 to 1969 inclusive (100 patients) and 1976 and 1977 (105 patients). Interlaminar discectomy was carried out in 88%, and laminectomy with spinal nerve nerolysis in 12%, of the 1965 - 1969 series. Discectomy by interlaminar approach was carried out in only 10% of the 1976 - 1977 series; all other patients had laminectomies with or without discectomies. Early follow-up results in the recent series indicate a significant (20%) increase in the number of patients who resumed their previous occupations as compared with those in the previous series.

[Surgical techniques of ventricular assist device].

Since October 1982 to April 1990, we had 16 ventricular assist device (VAD) cases in our institute. Using this VAD system that was produced by Nippon Zeon company, surgical techniques for cannulation and de-cannulation could be made very easily, and connection between cannulae and pump also could be performed quickly. In this article, the actual surgical techniques and the know-how were illustrated in detail. If this techniques can be more accustomed, the clinical results of VAD cases will be improved.

The surgical technique for hindquarter amputation. A report of 19 cases.

The surgical technique for hindquarter amputation is described in a step-by-step manner. Since 1955 we have performed 19 such operations for eradication of malignant bone and soft tissue tumors in the pelvic, hip and upper thigh regions. Three hindquarter amputations were performed for local recurrence following initial wide excision. The overall 5-year survival rate for our 19 patients was 42.1 per cent. Malignant soft tissue tumors appear to have a much better 5-year survival rate than malignant bone tumors (60 per cent vs. 22.2 percent). We feel that surgery is still the treatment of choice. However, in the presence of proper indications, chemotherapy and radiotherapy should be added to surgery in order to prolong survival time and save lives.
