[Surgical decompression and postoperative local action on the small intestine in the combined treatment of intestinal obstruction and peritonitis].
The results of using the operative methods of decompression of the gastro-intestinal tract in 151 patients with longstanding ileus and peritonitis are discussed. Methods of continuous decompression giving local effect upon the intestinal wall in the postoperative period should be used in the critical patients. The results of studying certain biochemical aspects of lavage of the small intestine are described.

Role of surgical decompression in ulnar neuritis of leprosy.
The present study was undertaken to evaluate the effect of neurolysis in relieving the pain of acute painful neuritis and assess its effect on the sensory motor deficit. Thirty eight ulnar nerves were operated and followed up for 8 to 125 weeks. Following surgery relief from pain was gratifying. However the pain recurred in cases of lepromatous leprosy in subsequent episodes of ENL reaction. Sensory recovery was appreciable and occurred within 8 weeks. Four cases had 75% recovery; five had 50 to 75% recovery and 11 cases had up to 50% recovery. Motor recovery took a longer time to appear. Proximal supplied muscles recovered first followed by smaller muscles. In most cases further deterioration of muscle power was prevented. Only 3 cases deteriorated. Recovery was more pronounced in LL cases. Patients with shorter duration of acute symptoms and history of smaller number of attacks of acute painful neuritis showed a higher incidence and better grade of recovery.

[Surgical decompression for massive cerebellar infarction].
The authors report 10 patients with progressive neurological deterioration due to massive cerebellar infarctions. Computerized tomography scans confirmed obstructive hydrocephalus and brain stem compression. All 10 patients (seven men, three women; mean age, 59 years) were treated by external ventricular drainage and decompressive suboccipital craniectomy. After discharge from the hospital, they were followed up (23-101 months) and their functional independence was evaluated by the Barthel Index. The condition of three patients with brain-stem infarction had deteriorated despite decompressive surgery. Two of these died during the acute stage and one because severely disabled. The remaining seven patients showed neurological improvement during the postoperative period. Four patients with preoperative Japan Coma Scale of 100 returned to their previous jobs within the follow-up period and three patients with preoperative Japan Coma Scale of 200 required some assistance in daily activities. It is suggested that decompressive surgery may be beneficial for massive cerebellar infarction. The postoperative prognosis depends mainly on the presence or absence of coexisting brain-stem infarction. It is possible that, without brain-stem infarction, patients who remained in a "dependent" state may have recovered better if they had been operated on earlier.

[Value of vertebroplasty combined with surgical decompression in the treatment of aggressive spinal angioma. Apropos of 3 cases].
Vertebral hemangiomas can cause difficult-to-treat neurological complications. We report our experience with three such cases. Patients no. 1 and 2 were females aged 64 and 71 years, respectively; patient no. 1 had a two-year history of weakness in the lower limbs and patient no. 2 had a five-month history of back pain. Both these patients had a pyramidal syndrome in the lower limbs. Patient no. 3 was a 61 year old male with a one-year history of left sciatica. Roentgenograms were suggestive of a hemangioma occupying the entire T8 (cases 1 and 2) or L5 (case 3) vertebra. Computed tomography and magnetic resonance imaging confirmed this diagnosis and showed that patients 1 and 2 had an anterior epidural hemangioma opposite T8 impinging on the spinal cord. In patients 1 and 2, treatment consisted in embolization of T8 followed by transpedicular injection of 6 cc of methylmethacrylate into the body of T8. One cubic centimeter of histoacryl was also injected in each lamina. The third patient had a similar vertebroplasty procedure without prior embolization since he had no epidural hemangioma. One patient (no. 1) developed intercostal neuralgia of several hours duration after the procedure. All three patients subsequently underwent laminectomy (T7-T8 with removal of the epidural hemangioma in cases 1 and 2, L5 in case 3). The pyramidal syndrome resolved within 15 days in patients 1 and 2; the nerve root pain resolved within 48 hours in patient 3.(ABSTRACT TRUNCATED AT 250 WORDS)

Lumbar spinal stenosis and diabetes. Outcome of surgical decompression.
We reviewed 25 diabetic (mean age 68 years) and 25 non-diabetic patients (mean age 71 years) who had undergone decompression for lumbar spinal stenosis at a mean of 3.4 years after operation to determine whether diabetes affected the outcome of surgery. The preoperative symptoms were similar in the two groups except that an abrupt onset of symptoms, the presence of night pain and the absence of any posture-related pain relief were recorded only by diabetic patients. Nerve-conduction velocity was slowed in 80% of the diabetic and in 25% of the non-diabetic patients. Peripheral vascular deficiency was diagnosed in 20% of patients with diabetes and in 4% of non-diabetics. The outcome of surgery was similarly successful in the two groups. Mistaken preoperative diagnosis was the cause of failure in three diabetic patients, two with diabetic neuropathy and one with diabetic angiopathy.

Surgical decompression for peroneal nerve palsy after total knee arthroplasty.
Five patients were treated by operative exploration and decompression of the peroneal nerve for peroneal nerve palsy complicating total knee arthroplasty (TKA). All patients had failed to demonstrate improvement in the peroneal nerve function despite extended conservative care. The procedure was performed five to 45 months after the index TKA. Patients were evaluated and graded preoperatively and postoperatively using the Modified Nerve Palsy Scale of Weber, Daube, and Coventry. All patients demonstrated improved nerve function. Four of five patients had full peroneal nerve recovery. All patients were able to discontinue their ankle-foot orthoses. This is a rare complication of TKA, and when conservative nonoperative measures do not lead to sufficient improvement in nerve function, consideration may be given to operative decompression of the peroneal nerve.

[Significance of simultaneous fusion and surgical decompression in lumbar spinal stenosis].
In a prospective study 45 patients with clinically relevant spinal stenosis of the lumbar spine were randomized in three groups. Group 1 underwent isolated decompression without fusion, group 2 had decompression and selected fusion, and group 3 underwent fusion of all decompressed segments. Patients with previous surgery of the lumbar spine or obvious instability, such as spondylolisthesis, were excluded from the study. The results were dominated by the relevant clinical improvement in the symptoms of spinal stenosis in all three groups. There were no statistical significant differences in the clinical results between the patients with and without fusion. We conclude that in the absence of obvious segmental instability, no fusion is required for decompressive surgery in degenerative lumbar spinal stenosis.

[Stenosis of the lumbar spine in elderly persons. Surgical decompression].
The degenerative changes in the lumbar vertebral spine frequently appear as encroachment of the lumbar spinal canal. Degenerative changes of the anatomical structures dictate the location of the stenosis, which are divided in central or lateral stenosis of the lumbar spinal canal. According to this localization, more radicular symptoms in a lateral stenosis might be prevalent in contrast to the mixed symptoms of a central stenosis. Operative decompression might be indicated in cases with correlation of clinical symptoms and radiological findings. The operative treatment aims at a satisfactory decompression without creating iatrogenic instability. An additional fusion might be avoided in cases without apparent instability. Adequate operative decompression is most efficient concerning reduction of pain and increasing of walking distance.

Evaluation of results of surgical decompression of median nerve in leprosy in relation to sensory--motor functions.
Median nerve decompression was performed in 29 leprosy patients of which 20 were followed up for varying periods. It has been observed that the decompression was beneficial, sensory recovery was seen in 90% cases and in 45% cases the muscle strength improved and the process of deterioration was arrested in another 25% cases.

Herpes simplex encephalitis: treatment with surgical decompression and cytosine arabinoside.
Herpes simplex encephalitis in a 21-year-old man presented as a flu-like illness, followed by inappropriate behaviour, drowsiness and focal neurologic signs. Investigations indicated a lesion in the right temporal lobe. The diagnosis was confirmed by isolation of the virus from a cerebral biopsy. Pronounced clinical improvement was noted when cytosine arabinoside therapy was started in the postoperative period. This report supports the observation by some authors that cytosine arabinoside may be of value in the treatment of herpes simplex encephalitis.

The sphenoidal sinus in optic nerve decompression.
Surgical decompression of the orbit may be necessary in dysthyroid patients with compressive optic neuropathy. Two-wall decompression with a trans-antral or a trans-conjunctival approach is commonly used. However, in some patients the initial improvement following this surgical procedure is not maintained. Although this may be due to disease progression, a variant of orbital anatomy can contribute to sub-optimal decompression. We report three cases in which recurrence of compressive optic neuropathy occurred following two-wall decompression. The sphenoidal sinus was placed anteriorly in these patients. Further decompression which included the lateral wall of the sphenoidal sinus resulted in improvement. An endoscopic approach provides superior access and visibility for decompression of the optic nerve into the sphenoidal sinus, and this approach may be the surgical treatment of choice in these cases.

Chiasmal apoplexy: hemorrhage from a cryptic vascular malformation in the optic chiasm.
We describe three patients with acute chiasmal visual field loss caused by hemorrhage within an intrachiasmal arteriovenous malformation. One patient had five episodes; vision improved three times without treatment and twice after surgical decompression. Surgical intervention restored vision in two of the three patients. The role for surgery is indefinite, but may be indicated if the visual defect remains static for 1 week or progresses. Decompression is likely to be most effective if done early. The approach to the optic chiasm should be transcranial, not transsphenoidal. A radiologically normal sella turcica favors the diagnosis of chiasmal apoplexy in the acute chiasmal syndrome.

The Rush-Presbyterian-St. Luke's lumbar spine analysis form: a prospective study of patients with "spinal stenosis".
A form for accurate and reproducible record keeping was introduced into the orthopedic practice of one author at Rush--Presbyterian--St. Luke's Medical Center (RPSLMC) in 1976 and has been used in the evaluation of each new patient with a lumbar spine problem since that time. In order to demonstrate the usefulness and effectiveness of this form, a small subset of these patients (i.e., those with "spinal stenosis") who had had decompressive surgical treatment were recalled, reexamined, and the form redone completely. The format of the form then was changed (without changing the content) in order to give a numeric score to the various clinical subcategories covered in the history and physical examination. Within the parameters studied, significant changes were found in both of the major categories of pain and objective physical findings. This suggested that patients with "spinal stenosis" obtained definite, measurable benefit from surgical decompression during the period of 1-3 years following their surgery.

Tarsal tunnel syndrome. Outcome of surgery in longstanding cases.
Cases of longstanding (median, 60 months) tarsal tunnel syndrome were decompressed surgically in 14 female and four male patients. Patients reported intermittent dysesthesia, paresthesia, or anesthesia at the medial plantar aspect of the foot. Symptoms were aggravated by physical activities. Previous trauma was noted in four patients. Tinel's sign was positive in 16 patients. Magnetic resonance imaging was performed in 10 patients but was conclusive in only two. At surgery, the posterior tibial nerve or one of its branches was found to be entrapped in 15 patients. Entrapments were observed isolated or in combination within the fascial septa (n = 5), varicose veins (n = 6), scar tissues (n = 4), tenosynovitis and edema (n = 1), or within the abductor hallucis muscle (n = 1). Two neuromas were excised. In three patients no obvious entrapments were found. Clinical followup was performed a median 18 months after surgery. Relief of symptoms was reported as long as 1 year after surgery. All symptoms were relieved in 11 (61%) patients. Three (17%) patients with previous trauma had relatively severe pain after surgery and were considered to have failed results. Surgical decompression was beneficial in most patients with longstanding tarsal tunnel syndrome.

[Surgical arteriovenous decompression (sheathotomy) in branch retinal vein occlusion: retrospective study].
PURPOSE: To evaluate best-corrected visual acuity (BCVA), incidence of neovascularization and angiographic changes in patients with branch retinal vein occlusion (BRVO) treated with surgical decompression by sheathotomy. METHODS: Retrospective study including 17 cases of temporal BRVO with macular edema treated with surgical decompression. Results of BCVA, incidence of neovascularization and vitreous hemorrhage 6 months following surgery are included. Angiographic changes in the first 8 cases a month after decompression are also evaluated. RESULTS: The mean postoperatory BCVA was 0.40 with a mean improvement of 0.26. Seventy one percent of patients (12/17) improved 2 or more visual acuity lines and 53% of patients (9/17) improved 4 or more lines. Only in one case the vision worsened. There was no evidence of retinal neovascularization or rubeosis iridis six months after surgery. CONCLUSIONS: Surgical decompression is a therapeutical option for those patients suffering BRVO with macular edema. Our initial results are encouraging, not only regarding visual acuity improvement, but also because of a decreased risk of neovascularization. No patient included in our study developed neovascularization.

Portal hypertension and shunt surgery.
Surgical shunts in the management of portal hypertension are one component of overall management. The main complications of portal hypertension is variceal bleeding. The very high mortality rate of this complication mandates careful assessment and appropriate treatment. Despite the introduction of new treatment methods such as pharmacologic reduction of portal pressure and endoscopic sclerotherapy, taken in conjunction with the coming of age of liver transplantation, surgical decompressive shunts still have a role in the overall treatment of these patients. The choice of therapy is based on full evaluation. The emphasis of that evaluation is on hepatic function. The patients who can live with their liver for an acceptable period of time and do not have the bleeding controlled with lesser medical managements require decompressive shunts. Surgical decompression of portal hypertension may also be required in the patient who is bleeding to death in the acute setting and, finally, is required for the treatment of acute Budd-Chiari syndrome. The choice of shunt procedures should take into account the potential for liver transplantation at some point in the future.
