The arthroscopic treatment of multidirectional shoulder instability: two-year results of a multiple suture technique.

Nineteen consecutive shoulders in 19 patients were treated for multidirectional shoulder instability with an arthroscopic capsular shift. Indications for the procedure included complaints of pain, instability, or both that was unresponsive to a prescribed exercise program that stressed rotator cuff and scapular stabilizer strengthening. All patients had evidence of increased joint laxity on physical examination; 17 had a 2+ or greater sulcus test and 2 had 3+ laxity both anteriorly and posteriorly. Fourteen of the 19 patients were injured during athletic activity. All surgeries were performed in an outpatient setting. All the patients were evaluated at an average of 34 months postoperatively with a minimum follow-up of 25 months. Based on the outcome scale described by Tibone and Bradley, the average postoperative score was 91 out of a possible 100 with 13 excellent, 5 good, and 1 fair result. All but 1 of the athletes returned to their previous level of performance but none were elite throwers. One patient had recurrent anterior subluxations treated with a repeat arthroscopic capsular shift and was rated as good. The patient rated as fair had no improvement in her pain after surgery. One patient complained of a painful supraclavicular suture that resolved spontaneously. There were no neurovascular complications or infections. Visualization of intra-articular pathology was enhanced with the arthroscope and aided in the diagnosis of multidirectional instability. The described technique proved safe and effective in treating multidirectional instability and enabling athletes to return to their previous level of function.

The arthroscopic treatment of posterior shoulder instability: two-year results of a multiple suture technique.

This study was undertaken to review the results of an arthroscopic posterior capsular shift procedure. Twenty consecutive shoulders in 19 patients were treated with an arthroscopic posterior capsular shift for symptomatic posterior shoulder instability. Patients underwent the procedure if they exhibited a posterior Bankart lesion or had complaints of posterior instability and evidence of increased posterior joint laxity on physical examination and examination under anesthesia. Twelve of the 20 patients were injured during athletic activity. All surgeries were performed in an outpatient setting. Twelve of the 20 patients had posterior Bankart lesions and 10 had anterior Hill-Sachs lesions. The procedure entails releasing the posterior labroligamentous structures from the posterior glenoid and freshening the glenoid neck with a bur. A suture punch is used to place multiple absorbable monofilament stitches in the ligament complex. The stitches are brought through a supraclavicular portal and tied over the clavicle or scapular spine. All 20 shoulders were evaluated at an average of 31 months postoperatively with a minimum follow-up of 24 months. Based on the outcome scale described by Tibone and Bradley, the average postoperative score was 83 out of a possible 100, with 15 excellent, 2 good, 1 fair, and 3 poor results. There were two recurrent dislocations and three subluxations for an overall recurrence rate of 25%. All the recurrences occurred in patients with posterior Bankart lesions and four of the five had a voluntary component to their instability. There were no neurovascular complications or infections. Arthroscopic evaluation facilitated the diagnosis of posterior instability with the visualization of intra-articular pathology that is difficult to identify during open procedures. Although the majority of patients were able to return to vigorous activities, a recurrence rate of 25% is disturbing and consistent with recurrence rates for open procedures.

Arthroscopic capsular plication for posterior shoulder instability.

Seventeen patients with recurrent posterior shoulder instability underwent posterior capsular plication with or without suture anchors, between 1990 and 1992. Minimum 2-year follow-up was available for 14 patients (average, 33 months; range, 24 to 45 months). The etiology involved trauma in 9 cases, recurrent microtrauma in 4 cases, and no trauma in 1 case. Posterior capsular laxity was present in all 14 cases and was believed to be the primary pathology, although 12 patients showed some form of labral pathology. The patients were interviewed and assessed in six categories: pain, strength, function, stability, range-of-motion, and satisfaction. Twelve patients had excellent results and 2 had fair results. Nine of 10 patients who participate in recreational or competitive athletics reported full return to their preinjury level of function in their respective sports. There was one recurrence of posterior shoulder instability which was remedied with a second arthroscopic posterior capsular reconstruction. All 14 patients were satisfied with the results of their surgery, and no complications were noted. Capsular plication is a promising technique in the treatment of recurrent posterior shoulder instability.

The low anterior five-o'clock portal during arthroscopic shoulder surgery performed in the beach-chair position.

We evaluated the difficulty, accuracy, and safety of establishing a low anterior 5-o'clock portal for anterior capsulolabral repair in patients positioned in the beach-chair position during shoulder arthroscopy. An initial 5-o'clock portal was created using an inside-out technique as described by Davidson and Tibone. During establishment of the portal, significant force was required to lever the humeral head laterally, and chondral indentations were noted in several specimens. Because of the difficulty noted establishing the 5-o'clock portal using an inside-out technique, we attempted to establish a 5-o'clock anterior portal using an outside-in technique. Seven fresh-frozen cadaveric shoulders underwent shoulder arthroscopy in the beach-chair position. After the establishment of a 3-o'clock portal, a specially constructed guide was used to place a pin at the 5-o'clock position. The distances of the pins from the cephalic vein and the musculocutaneous and axillary nerves were recorded. The bottom (5-o'clock position) and top (3-o'clock position) pins varied from 12 to 20 mm from the musculocutaneous and axillary nerves. The bottom pin was located within 2 mm of the cephalic vein and varied from medial to lateral in different specimens. We do not recommend the use of a 5-o'clock portal using an inside-out or outside-in technique for patients positioned in the beach-chair position during shoulder arthroscopy because of the potential for cephalic vein or articular cartilage injury.

Glenohumeral joint range of motion and rotator cuff strength following arthroscopic anterior stabilization with thermal capsulorraphy.

STUDY DESIGN: Single-session, posttest only, descriptive analysis of range of motion (ROM) and strength. OBJECTIVES: To measure ROM and strength approximately 12 weeks following arthroscopic anterior stabilization of the glenohumeral joint with thermal capsulorraphy. BACKGROUND: Treatment of the patient with anterior, unidirectional glenohumeral joint instability often includes surgical stabilization. Current methods focus on arthroscopic stabilization and early ROM and strengthening to restore normal function to the upper extremity. METHODS AND MEASURES: Twenty patients diagnosed with unidirectional shoulder instability (mean age 24.5 years, SD = 8.48) underwent a postoperative rehabilitation program following unilateral arthroscopic shoulder stabilization with thermal capsulorraphy. Objective testing including ROM and isokinetic internal rotation (IR) and external rotation (ER) strength at 90, 210, and 300 degrees/s was performed 12 weeks postoperatively. RESULTS: Ten patients had a complete return of shoulder flexion ROM at 12 weeks. There were deficits compared to the noninjured extremity in postoperative glenohumeral joint mean abduction (9.8 +/- 12.7 degrees), IR (8.4 +/- 15.0 degrees), and ER (13.1 +/- 14.4 degrees). Isokinetic testing showed a complete return of ER strength on the postoperative extremity compared to the uninjured extremity for 12 patients with a 4% (+/- 21.1%) mean deficit measured in IR strength at the slowest testing velocity. No significant difference was found between extremities in the external/internal rotation ratios. CONCLUSION: Postoperative rehabilitation emphasizing progressive ROM and rotator cuff and scapular strengthening has produced favorable results in patients 12 weeks postoperatively with respect to glenohumeral joint ROM and IR and ER strength. Further research and follow-up is required to obtain long-term outcomes with respect to patient satisfaction and stability of the glenohumeral joint following this arthroscopic procedure.

[The enteroscopy capsule--a swallowable instrument for video examination of the small bowel].

Since 1.5 years wireless enteroscopy with the GivenM2A-capsule has been tested clinically. Wireless capsule-enteroscopy (WCE) has already contributed significantly to the understanding of patients with obscure intestinal symptoms. Series of occult bleeders show that WCE detects lesions in 60%, whereas enterography only in 15%, and push-enteroscopy in 25%. Lesions detected are angiodysplasia in 55%, ulcerations in 14%, apthoid lesions and erosions in 11%, tumours in 8%. Active bleeding was seen in 43%. In patients with Crohn's disease further information on extent of disease and type of lesions is gained, mainly seen as erosions in 64%. WCE in hereditary polyposis disclosed more and bigger lesions, and in celiac enteropathy villous atrophy and scalloping of the mucous membrane is readily identified. Software to locate the capsule in the gastrointestinal tract is recently launched together with a graphic display of capsule track and transit times. Soon displays for motility and pressure will follow. Capsule adaptation for screening for Barrett's esophagus and colon cancer might come true.

Multicenter clinical trial of zinc acexamate in the prevention of nonsteroidal antiinflammatory drug induced gastroenteropathy. Spanish Study Group on NSAID Induced Gastroenteropathy Prevention.

OBJECTIVE: To assess in a multicenter double blind clinical trial the gastroenteroprotective effect of zinc acexamate (ZAC). METHODS: 276 patients with rheumatic disease and history of peptic ulcer or intolerance to nonsteroidal antiinflammatory drugs (NSAID), and requiring treatment with these drugs were included. An initial normal endoscopy was needed for inclusion. Patients were treated with one NSAID (diclofenac, piroxicam, naproxen or ketoprofen) and one capsule (300 mg) of either ZAC (141 patients) or placebo (135 patients) at single nocturnal dose. After 28 days, patients underwent a clinical and endoscopic control. RESULTS: 26 patients withdrew from the trial (10 of ZAC and 16 of placebo) and 41 were lost to followup (22 of ZAC and 19 of placebo). Gastroduodenal mucosal damage was graded according to a modified Lanza score. The incidence of gastric ulcer was null with ZAC and 6.0% with placebo (6 cases) (p < 0.05). The incidence of duodenal ulcer was 0.9% with ZAC (1 case) and 6.0% with placebo (12 cases) (p < 0.001). Nine patients of ZAC group (8%) and 25 of placebo (25%) presented some gastric damage (p < 0.001), and 5 (5%) and 19 (19%) respectively presented some duodenal damage (p < 0.005). After treatment, 88% of patients treated with ZAC and 66% with placebo had a completely normal endoscopy (p < 0.0005). No major side effects were reported through the study. CONCLUSION: ZAC has shown to be effective and well tolerated for the prevention of NSAID induced gastroduodenal damage in patients with rheumatic disease at risk. The incidence of gastric and duodenal ulcers decreased in 92% (13 times the risk), when compared to placebo.

Breath and string test: a diagnostic package for the identification of treatment failure and antibiotic resistance of Helicobacter pylori without the necessity of upper gastrointestinal endoscopy.

AIM: Helicobacter pylori (H pylori) resistance after failed eradication has a major impact on the outcome of a further treatment regimen. The aim of this study was to assess the validity of a non-invasive strategy using the 13C-urea breath test (UBT) and the gastric string test in identifying post-treatment resistance of H pylori. METHODS: The UBT was routinely performed 4 to 6 wk after H pylori eradication therapy. Forty-two patients (24 females, 18 males, mean age 48 years) with a positive UBT were included in the study. A gastric string test using a capsule containing a 90 cm-long nylon fiber was performed. Before the capsule was swallowed, the free end of the string was taped to the cheek. After one hour in the stomach, the string was withdrawn. The distal 20 cm of the string was inoculated onto an agar plate and processed under micro-aerophilic conditions. Following the string test, upper gastrointestinal endoscopy was performed to obtain gastric biopsies for conventional culture. RESULTS: H pylori was successfully cultured from the gastric string in 34 patients (81%), but not in 5 patients due to contamination with oropharyngeal flora. H pylori was cultured from the gastric biopsies obtained at endoscopy in 39 patients (93%). CONCLUSION: The UBT followed by the gastric string test in the case of treatment failure is a valid diagnostic strategy with the aim of determining the post-therapeutic antibiotic resistance of H pylori with little inconvenience to the patient. Upper GI-endoscopy can be avoided in several cases by applying consequently this diagnostic package.

Fifteen-year follow-up of arthroscopic partial meniscectomy.

From an original pool of 283 patients, 146 patients who had undergone arthroscopic partial meniscectomy an average of 14.7 years before were followed-up. Lysholm score, Tegner activity level, satisfaction index on a scale of 1 to 10, and standing anteroposterior and flexion weight-bearing radiographs of both knees, were obtained. A physical examination was performed on each knee emphasizing motion, swelling, and ligament evaluation. Radiographs were graded for degenerative changes for each knee. Each knee joint space was also measured in millimeters and compared, operative knee with unoperated knee. The unoperated knee had no injuries or surgeries and was used as a control. Patients were 83% male and 17% female; 78% had undergone medial meniscectomies, 19% lateral, and 3% both. There were 88% good and excellent results in anterior cruciate ligament-stable knees. The radiographic grade side-to-side difference showed the operative knee to be only a 0.23 grade worse than the nonoperative knee. Age at the time of meniscectomy was not found to be a factor. Male patients had better radiographic results than female patients, but not better functional scores. Medial meniscus and lateral meniscus results were not significantly different. Knees with a femoral-tibial anatomic alignment of > 0 degree valgus compared with < or = 0 degree and that had undergone medial meniscectomy had significantly better radiographic results. Patients with anterior cruciate ligament tears and meniscectomy did significantly poorer than stable knees with meniscectomy in regards to radiographic grade change, Lysholm, satisfaction index, Tegner level, and medial joint space narrowing.

Combined Bankart and HAGL lesion associated with anterior shoulder instability.

Traumatic anterior shoulder instability has been shown to be associated with a spectrum of capsulolabral pathology, including separation of the labrum (Bankart lesion), capsular rupture, and humeral avulsion of the glenohumeral ligaments (HAGL lesion). We describe a case of combined Bankart and HAGL lesions, a condition that has not been described before. Careful anatomic repair of both components of this bipolar capsular injury resulted in an excellent outcome.

Congestive jejunopathy in portal hypertension.

Twenty six patients with portal hypertension of different aetiologies were studied for endoscopic evidence of congestive gastroduodenopathy and histological evidence of congestive gastropathy and jejunopathy. Per oral biopsies of jejunum were taken by Watson's capsule. Normal biopsy tissues obtained from the antrum (26), fundus (10), and jejunum (26) were used as controls. Endoscopy showed congestive changes in the fundus (17 cases), antrum (17), and duodenum (4). Duodenopathy correlated with changes in the antrum but not in the fundus. Histology showed an increase in the size and number of vessels in the jejunal villi ('congestive jejunopathy') in 22 patients. These correlated with histological evidence of gastropathy in the fundus but not in the antrum. The incidence of congestive jejunopathy did not correlate with the Child-Pugh score in patients with cirrhosis or with the number of sclerotherapy sessions received. Congestive jejunopathy is part of the spectrum of congestive gastroenteropathy and occurs at least as frequently as changes in the stomach and duodenum. The clinical import of these jejunal changes remains to be explained.

[Peutz-Jeghers syndrome: variability of gastrointestinal expression at pediatric age].

Peutz-Jeghers syndrome is a rare autosomal dominant condition, characterized by gastrointestinal polyposis, mucocutaneous pigmentation and high risk of neoplasia in multiple organs. At pediatric age, major clinical impact is related to complications associated to intestinal polyps, but neoplasic risk isn't negligible. Though clinical surveillance is recommended since the age of 10 years, relevant lesions may occur before that age. Conventional radiology and endoscopy have recognized limitations at this age group, and new diagnostic and intervention tools, such as video-capsule and per-operative enteroscopy, are not yet widely used. We present 5 pediatric cases (age under 10 years) with diversity of gastrointestinal expression (including one case with histologic evidence of dysplasia in a large colonic polyp), emphasizing the need of specific guidelines concerning young children.
