Laparoscopic salvage of malfunctioning peritoneal catheters.

BACKGROUND: Malfunction of peritoneal catheters due to mechanical outflow problems is an annoying complication in patients undergoing chronic peritoneal dialysis (PD). Correction often involves catheter replacement or revision via laparotomy. METHODS: Twenty-five patients undergoing PD who developed mechanical catheter flow restriction underwent 28 laparoscopic procedures. Preoperative diagnoses were made by contrast catheter radiography and were: catheter sequestration (36%), omental wrap (64%). Pneumoperitoneum was induced after general anesthesia and laparoscopy was performed using a Storz laparoscope. The catheter was then identified and manipulation was attempted using instruments placed percutaneously. RESULTS: In 26 cases (93%), the catheter was freed and function restored. In two cases (7%), adhesions were so numerous and dense that the distal catheter could not be visualized. Four episodes of peritonitis developed subcutaneous leakage of peritoneal fluid which responded to cessation of PD for 2 weeks. Four patients had recurrent occlusions; three of these were managed laparoscopically. Two patients developed late hernias at the site of insertion of the laparoscope. Catheter patency averaged 9.2 months postoperatively. CONCLUSIONS: Laparoscopic revision is a successful technique for salvage of occluded peritoneal catheters.

Predictive factors for the outcome of anterior cervical decompression and fusion.

In a prospective study, 103 patients were randomised to anterior cervical decompression and fusion (ACDF) with a cervical carbon-fibre intervertebral fusion cage or the Cloward procedure. Preoperative background variables, active range of neck motion, handgrip strength, radiological evaluation and subjective variables were used in a multiple regression model to find the strongest predictors of postoperative outcome as measured by current pain intensity and the Neck Disability Index (NDI). Male sex, greater kyphosis at the level operated on, non-smoking, a greater neck mobility in right rotation, low disability on NDI, and older age were predictors of pain reduction and explained 30% of current pain intensity at follow-up. Higher educational level, non-smoking, greater kyphosis at the level operated on, a greater flexion mobility, greater right handgrip strength and lower current pain intensity were predictors of improvement, and explained 28% of the postoperative outcome on NDI. The most important predictor for postoperative pain intensity was the magnitude of the preoperative kyphosis. Preoperative pain intensity was the most important predictor for improved NDI. At follow-up about 70% of the patients still had deficit based on current pain intensity and NDI, and 44% had remaining dysfunction based on Odom's criteria. In conclusion, the multivariate analysis shows that male sex, non-smoking, greater segmental kyphosis and a low pain and disability level are preoperative predictors of a good outcome in ACDF. In addition, the study suggests the importance of other predictive variables than those studied for the outcome of ACDF.

Hemorrhoidopexy staple line height predicts return to work.

PURPOSE: Previous studies identified reduction in pain and complications with stapled hemorrhoidopexy relative to conventional hemorrhoidectomy. Previously, the presence of resected squamous epithelium and a staple line height <20 mm above the dentate line were predictive of postoperative pain. The purpose of this study was to further investigate and refine the role of staple height in the prediction of postoperative outcomes. METHODS: From July 2002 to October 2004, 75 patients with symptomatic Grade 3 and 4 mixed hemorrhoids underwent stapled hemorrhoidopexy in two teaching institutions with prospective data collection. All procedures were performed under the direct supervision of two colorectal teaching staff. The majority were performed under monitored anesthesia care as outpatient procedures. Preoperative, intraoperative, and postoperative patient characteristics were evaluated. This included demographics, staple line height, specimen histology, complications, days to return to work, duration of narcotic pain medicine, and preoperative/postoperative tone and seepage. The results were subjected to statistical analysis using t-test and ANOVA. RESULTS: Seventy-five patients with a median age of 49 (range, 25-87) years were identified. Histology identified 62 specimens with columnar and/or transitional cells, 10 with squamous epithelium, and 3 with muscle present. Overall complication rate was 14 percent. Complications included three readmissions for pain control, three acute postoperative anal fissures, two postoperative bleeds (with one requiring examination under anesthesia without intervention), one patient with subcutaneous emphysema, and one admission for fecal impaction. Staple line height was not a statistically significant predictor of postoperative complication. Median return to work was 14 (range, 1-31) days. Median duration of narcotic use was six (range, 0-40) days. Patients with a staple line height>22 mm required a significantly shorter duration of narcotic pain management (P=0.024). Median follow-up was 24 (range, 9-253) days. Staple line heights below 20 mm had a mean return to work of 15 days. A staple line height>20 mm had a mean return to work of nine days. Staple line height was inversely related to return to work (P=0.01). CONCLUSIONS: A hemorrhoidopexy staple line>or=22 mm above the dentate line correlates with a significantly shorter need for postoperative narcotics (P=0.024) and an earlier return to work (P=0.017). Staple line distance above the dentate line meaningfully impacts comfort-based outcomes.

Diagnostic significance and sequelae of cone biopsy.

All cone biopsies from our institution over a 10-year period were reviewed. Two hundred seventy-one patients underwent 274 procedures. Preoperative colposcopic evaluation markedly reduced the proportion of patients with residual cervical epithelial neoplasia (CIN). No patient in our series required conization for diagnosis of frankly invasive carcinoma. Following colposcopy and conization, 8% of patients had disease extending to the surgical margins; eight of 11 such patients (72%) with adequate follow-up had no further CIN. Colposcopy and cytology underestimate the final pathologic diagnosis in many patients with incomplete visibility of the transformation zone, so conization is mandatory in this circumstance. Conization in pregnancy was associated with increased hemorrhage; colposcopy has reduced the need for this operation in gravid patients.

Antiglaucomatous ciliary body excision.

Between 1974 and 1984, we performed 106 ciliary body excisions in a total of 90 eyes. Of the 85 eyes for which at least six months of follow-up data were available, 72 had secondary partial angle-closure glaucoma with aphakia, ten had secondary partial angle-closure glaucoma without aphakia, and three had secondary open-angle glaucoma. Forty-eight eyes had undergone three or more (in some cases as many as nine) previous antiglaucomatous procedures before ciliary body excision and 27 had undergone one or two previous procedures. Preoperative intraocular pressures ranged from 35 to 60 mm Hg. After six months, intraocular pressure was 19 mm Hg or less in 60 eyes with no other treatment, although ten eyes required a second excision. Another five eyes had intraocular pressures of 19 mm Hg or less with medical therapy (one reoperation) and seven had intraocular pressures of 22 mm Hg or less without medical therapy (one reoperation). Ciliary body excision failed in 13 eyes. Four of these had persistent hypotony (intraocular pressures of less than 4 mm Hg) and nine had intraocular pressures above 40 mm Hg. Reasons for failure included rubeosis iridis (seven eyes), an overlarge excision (three eyes), and expulsive hemorrhage, siderosis bulbi, and Lowe's syndrome (one eye each). Postoperative visual acuity was unchanged in 45 eyes, somewhat improved in 15, and worse in 21.

Heterotopic brain tissue in the scalp.

A posterior midline cutaneous lesion in the scalp of a 15-month-old child was excised. Clinical examination, extensive investigations and finally surgery revealed no intracranial connection. Histologically, the lesion was composed of well differentiated meningeal, glial and cerebral tissues, establishing it to be heterotopic brain tissue. Even when all preoperative procedures exclude the diagnosis of cephaloceles, surgeons should keep in mind the possibility of an intracranial connection of any midline scalp lesion in a child and the subsequent risk of meningitis.

Mitral regurgitation due to ruptured chordae tendineae in patients with hypertrophic obstructive cardiomyopathy.

Mitral valve regurgitation in association with hypertrophic obstructive cardiomyopathy is usually caused by the systolic anterior motion of the anterior mitral leaflet. Recently, five patients were encountered with hypertrophic obstructive cardiomyopathy who had mitral regurgitation due to ruptured chordae tendineae. The diagnosis was confirmed in all patients during operation for left ventricular septal myectomy-myotomy (Morrow procedure). Preoperative identification of ruptured chordae tendineae as the cause of mitral regurgitation was established by transesophageal echocardiography in the three most recent cases. All patients had successful septal myectomy-myotomy for relief of left ventricular outflow obstruction, and mitral valve competence was restored by valve repair rather than by prosthetic valve replacement. The clinical course of these patients illustrates important management considerations as well as the utility of transesophageal echocardiography for diagnosis. Chordal rupture should be considered in the differential diagnosis of mitral regurgitation in patients with hypertrophic obstructive cardiomyopathy, especially in those with acute hemodynamic deterioration.

Pre-operative stability of infantile esotropia and post-operative outcome.

PURPOSE: To define the prevalence and time course of significant changes in angle of deviation during the first months after the diagnosis of infantile esotropia and to determine whether long-term alignment and sensory outcomes differ when surgical alignment is performed on infants with stable vs unstable angles of deviation. DESIGN: Prospective cohort study. METHODS: setting: Institutional and clinical practice. patient population: Newly diagnosed patients with infantile esotropia (N = 208). observation procedure: Preoperative measurements of the angle of deviation on the initial visit and at approximate six-week intervals until surgery was performed. main outcome measures: Ocular alignment at six weeks, one year, and four years postoperative and stereoacuity at age five to nine years. RESULTS: Overall, 57% of infants had an esodeviation on the second visit that was within 10 prism diopters (p.d.) of the deviation measured on the initial visit (stable group), 33% had an increase of 10 p.d. or more (unstable group), and 11% had a decrease of 10 p.d. or more. Among the 127 patients with additional preoperative visits, many switched between the stable and unstable categories during follow-up. Long-term, stable and unstable preoperative alignment groups had similar postoperative motor alignment, re-operation rates, rates of prescription of hyperopic, or bifocal spectacle correction and stereoacuity. CONCLUSIONS: It may not be necessary to wait for a "stable" angle of esodeviation before surgery since both alignment and sensory outcomes were similar for stable and unstable groups.

The effectiveness of tension-free vaginal tape (TVT) and quality of life measured in women with previous urogynecologic surgery: analysis from The Netherlands TVT database.

OBJECTIVE: Long-term outcome of tension-free vaginal tape (TVT) in women with a history of surgery for urinary incontinence and/or prolapse. STUDY DESIGN: Prospective cohort study of 809 women. Twenty-eight teaching and 13 local hospitals, 54 gynecologists and urologists performed the TVTs. The Incontinence Impact Questionnaire (IIQ-7) and Urogenital Distress Inventory (UDI-6) were used to measure the results of the TVT procedure (preoperative at 2, 6, 12, 24, and 36 months postoperative). According the recommendation of the International Continence Society, the question "Do you experience urinary leakage during physical activity, coughing or sneezing?" was selected from the UDI to assess stress urinary incontinence. RESULTS: The decrease in IIQ/UDI mean scores was statistically significant. The UDI scores of women with a history of previous prolapse and/or incontinence surgery were not statistically different to the scores for primary cases after 3 years follow-up (P = .193). CONCLUSION: TVT is effective for women with recurrent stress urinary incontinence and/or previous prolapse surgery.

Comparison of water seal and suction after pulmonary lobectomy: a prospective, randomized trial.

BACKGROUND: The objective of the present study was to assess whether placing chest tubes on water seal after pulmonary lobectomy reduced the duration of air leak compared with suction. METHODS: One hundred forty-five patients who underwent pulmonary lobectomy for lung cancer and with an air leak on the first postoperative day were prospectively randomly assigned to two groups: in group 1 (72 patients), chest tubes were placed on water seal on the morning of the first postoperative day; in group 2 (73 patients), chest tubes were on continuous suction (-20 cm H(2)O). Eighty percent of the patients who underwent upper lobectomy had also a pleural tent procedure. Preoperative, operative, and postoperative variables were compared between the groups. RESULTS: The two groups were evenly matched for preoperative and operative characteristics. No statistically significant differences were found between group 1 and group 2 in terms of air leak duration (6.5 versus 6.3, respectively; p = 0.9) and the incidence of prolonged air leak cases (27.8% versus 30.1%, respectively; p = 0.8). Similar results were obtained when the analysis was corrected for the length of the stapled parenchyma and the site of resection (upper and lower resections) or restricted to patients with a forced expiratory volume in 1 second less than 80% of predicted. Water seal patients had increased postoperative complications compared with suction patients (31.9% versus 17.8%, respectively; p = 0.056). CONCLUSIONS: Chest tubes placed on water seal after pulmonary lobectomy were generally well tolerated and safe; however, they did not reduce the duration of air leak or the incidence of prolonged air leak compared with suction.

Does pancreatic duct stenting decrease the rate of pancreatic fistula following pancreaticoduodenectomy? Results of a prospective randomized trial.

Pancreatic duct stenting remains an attractive strategy to reduce the incidence of pancreatic fistulas following pancreaticoduodenectomy (PD) with encouraging results in both retrospective and prospective studies. We performed a prospective randomized trial to test the hypothesis that internal pancreatic duct stenting reduces the development of pancreatic fistulas following PD. Two hundred thirty-eight patients were randomized to either receive a pancreatic stent (S) or no stent (NS), and stratified according to the texture of the pancreatic remnant (soft/normal versus hard). Four patients were excluded from the study; in three instances due to a pancreatic duct that was too small to cannulate and in the other instance because a total pancreatectomy was performed. Patients who randomized to the S group had a 6-cm-long segment of a plastic pediatric feeding tube used to stent the pancreaticojejunostomy anastomosis. In patients with a soft pancreas, 57 randomized to the S group and 56 randomized to the NS group. In patients with a hard pancreas, 58 randomized to the S group and 63 randomized to the NS group. The S and NS groups for the entire study population, as well as for the subgroup of high-risk patients with soft pancreata, were similar as regard to demographics, past medical history, preoperative symptoms, preoperative procedures, and intraoperative data. The pancreatic fistula rate for the entire study population was 9.4%. The fistula rates in the S and NS subgroups with hard pancreata were similar, at 1.7% and 4.8% (P = 0.4), respectively. The fistula rates in the S and NS subgroups with soft pancreata were also similar, at 21.1% and 10.7% (P = 0.1), respectively. A nonstatistically significant increase in the pancreatic fistula rate in the S group persisted after adjusting for the operating surgeon and technical details of the operation (e.g., anastomotic technique, anastomotic orientation, pancreatic duct size, and number of intra-abdominal drains placed). In patients with soft pancreata, 63% percent of the pancreatic fistulas in stented patients required adjustment to the clinical pathway (including two deaths), compared to 47% of the pancreatic fistulas in patients in the NS group (P = 0.3). Internal pancreatic duct stenting does not decrease the frequency or the severity of postoperative pancreatic fistulas.

Significance of asymptomatic tonsil asymmetry.

OBJECTIVE: Asymmetry of tonsils that arouses suspicion for malignancy is one of the indications for tonsillectomy. The purpose of this study was to evaluate the incidence of occult malignancy in patients with asymptomatic unilateral tonsillar enlargement. Study design and setting A prospective controlled trial was carried out in two institutions, Beyoglu Research and Training Hospital and Karaelmas University Hospital, during a 6-year period. Of patients selected for tonsillectomy, patients with unilateral tonsillar enlargement were identified and were included in this study. Patients who had risk factors that were significant for malignancy were excluded. After excision, two tonsil specimens were measured before sending for histology. Matched controls with symmetric tonsils underwent the same procedures. Preoperative diagnosis of tonsil asymmetry with the postoperative histologic diagnosis were correlated for the incidence of malignancy. RESULTS: Of the 792 patients undergoing tonsillectomy, 53 patients (6.69%) with asymmetry of tonsils and who had no other risk factors for malignancy underwent tonsillectomy. The size difference of the tonsils ranged from 0 to 19 mm. In the control group of 51 patients with symmetric tonsils, the size difference ranged from 0 to 8 mm. The analysis showed statistically significant difference in the degree of asymmetry between the two groups (P <.001). Most of the specimens contained reactive lymphoid hyperplasia in both groups (58.49% and 54.9%, respectively). No malignancies or unusual pathological findings were encountered on histologic examination in either group. Conclusion and significance Tonsil asymmetry may only be apparent in patients with an otherwise normal physical examination, secondary to benign hyperplasia or anatomical factors. Therefore, the presence of tonsil asymmetry without factors such as suspicious appearance, significant systemic signs and symptoms, progressive enlargement of the tonsil, concomitant neck adenopathies, and history of malignancy or immunocompromise, may not indicate malignancy, as a sole clinical feature.

Percutaneous chordotomy for managing cancer pain.

Pain is a problem frequently encountered by patients with cancer. For more than 30 years, the percutaneous chordotomy procedure has been a nonpharmacological approach to the management of intractable cancer pain. Nursing care of patients before, during, and after the percutaneous chordotomy procedure is challenging. Patients and their family members need to be educated about the intent and outcomes of the procedure, as well as its complications. The purpose of this article is to review the theoretical aspect of pain perception and outline the anatomical background and basic steps of the percutaneous chordotomy procedure. Preoperative patient education and preparation, intraoperative nursing interventions, and postoperative patient care are discussed.

Stent-graft placement procedures for descending thoracic aortic aneurysms.

Descending thoracic aortic aneurysms most often are caused by arteriosclerosis and appear most frequently in elderly males. These patients often are asymptomatic, but they may experience symptoms related to compression of adjacent thoracic structures, or they may present for treatment when their-aneurysms rupture. Open surgical resections and repairs of descending thoracic aortic aneurysms are associated with bleeding, paraplegia, strokes, renal insufficiency, and the need for prolonged ventilatory support in the postoperative period. At Stanford (Calif) University Hospital, surgeons are placing endovascular stent-grafts in patients with descending thoracic aortic aneurysms who meet specific anatomic selection criteria. This new treatment modality provides patients with a less invasive, less hazardous, and potentially less expensive alternative to open surgical resection and repair procedures. Preoperative teaching and skilled perioperative nursing care are essential for positive patient outcomes with stent-graft treatment of descending thoracic aortic aneurysms.

Phototherapeutic keratectomy.

The US Food and Drug Administration recently approved the 193-nm excimer laser for the treatment of superficial corneal pathology and surface irregularities--a procedure called phototherapeutic keratectomy (PTK). Indications for PTK include corneal dystrophies, degenerations, and scars that impair corneal transparency, thus compromising visual acuity. In some cases, PTK may offer a better treatment modality than corneal transplant surgery. This article reviews the basic fundamentals of PTK, including indications for surgery, the surgical procedure, preoperative and postoperative patient evaluation and care, and possible complications.

Improved patient selection for angioplasty utilizing color Doppler imaging.

The accepted approach to patients with intermittent calf claudication is nonoperative unless the symptoms are truly incapacitating, in which case arteriography and either percutaneous angioplasty or operation is indicated. Arteriography is considered a preoperative procedure. However, with improvements in percutaneous angioplasty, we have altered our approach to those patients with limiting, but not incapacitating, claudication. These patients are given the choice of conservative treatment or percutaneous angioplasty, but not operation. In an attempt to limit arteriography to only those patients who would benefit from angioplasty, we have employed color Doppler imaging as a screening technique. Over a 2-year period, 62 patients with limiting claudication were evaluated with color Doppler imaging. Thirty-six patients had long occlusions and did not undergo arteriography since they were not believed to be candidates for percutaneous angioplasty. Three short (less than 5 cm) occlusions and 23 localized stenoses were identified in the superficial femoral and popliteal arteries. Angiography confirmed the Doppler findings in all 26 cases. In 24 patients, dilatation was successful, whereas 2 patients' arteries could not be dilated. Two stenoses recurred early and were redilated. There were no complications from the angioplasties. We conclude that in the subset of patients with limiting, but not incapacitating, claudication, color Doppler imaging can accurately select those patients who will benefit from angioplasty. In this way, patients can be spared unnecessary angiograms.

Clinical experience with the Smeloff-Cutter prosthesis: 1- to 12-year follow-up.

To determine the long-term results of aortic valve replacement with the Smeloff-Cutter prosthesis, the fate of 358 of 459 (78%) consecutive patients was determined 1 to 12 years postoperatively. There were 319 male patients (70%). Mean age at operation was 57 years (range, 15 to 84 years). Aortic stenosis was the dominant lesion in 267 patients (58%) and aortic regurgitation in 133 patients (29%). Fifty-nine patients (13%) had both aortic stenosis and regurgitation. In addition to aortic valve replacement, 93 patients (20%) had coronary artery bypass, 30 (6.5%) had mitral commissurotomy, 23 (5%) had mitral valve replacement, and 41 (9%) had other procedures. Preoperative status by New York Heart Association Functional Class was: Class I, 3 (1%); Class II, 39 (8%); Class III, 148 (32%); and Class IV, 269 (59%). Operative (30-day) mortality was 8.5% (39 out of 459). Functional improvement was obtained in all postoperative survivors: 345 (82%), Class I; 63 (15%), Class II; and 12 (3%), Class III. A perivalvular leak developed in 6 patients (1%) and subacute bacterial endocarditis in five (1%). Actuarial long-term survival was 80% at 5 years and 71% at 8 years. Thromboembolism occurred in 34 patients (9.5%). The incidence of thromboembolism per 100 patient-years for patients receiving no anticoagulants was 5.4; antiplatelet agents, 2.9; and Coumadin (sodium warfarin), 2.6. Major thromboembolism was uncommon in patients on a regimen of sodium warfarin but major morbidity from bleeding was significant.

Repair of left ventricular aneurysm: long-term results of linear repair versus endoaneurysmorrhaphy.

BACKGROUND: Recently, endoaneurysomorrhaphy has been proposed as a more physiologic repair of postinfarction left ventricular aneurysm than is linear repair. There are only a few studies comparing the short-term and long-term results of the two techniques. METHODS: Clinical outcomes and echocardiographic measurements of left ventricular volume and sphericity in 27 patients who underwent endoaneurysmorrhaphy were compared with those in 20 patients who had linear repair. RESULTS: The two groups were matched with respect to age, gender, comorbid risk factors, functional class, urgency of the operation, and concomitant procedures. Preoperatively, left ventricular ejection fraction was lower in the endoaneurysmorrhaphy group (0.25 +/- 0.08 versus 0.30 +/- 0.09; p = 0.03). Follow-up was available in 44 patients (94%) and ranged from 2 to 86 months (mean, 41.0 +/- 26.5 months). Thirty-day operative mortality, perioperative complications, 5-year survival, and freedom from cardiac death were similar. Early postoperative percentage increase in left ventricular ejection fraction was greater after endoaneurysmorrhaphy (0.51 +/- 0.64 versus 0.18 +/- 0.48; p = 0.036). Long-term functional improvement was significantly better in the endoaneurysmorrhaphy group: At the time of last follow-up, 88% of patients were in New York Heart Association class I/II, compared with 53% after linear repair (p = 0.01). There were no measurable differences between the groups with respect to left ventricular ejection fraction (0.28 +/- 0.11 versus 0.27 +/- 0.11; p = 0.90), left ventricular volume (171.6 +/- 59.1 versus 169.9 +/- 54.4 mL; p = 0.94), and sphericity index (0.61 +/- 0.09 versus 0.61 +/- 0.12; p = 1.0). CONCLUSIONS: Despite having a similar effect on left ventricular geometry, endoaneurysmorrhaphy resulted in a greater increase in postoperative left ventricular ejection fraction and a substantially improved long-term clinical outcome.
