Background: Femoral artery vascular complications are the most common adverse events following cardiac catheterization. Smaller diameter introducer sheaths and catheters are likely to lower the puncture site complication rate but may hinder visualization.

Objectives: To evaluate the safety and angiographic quality of 4 French catheters.

Methods: The study was designed to simulate real-life operator-based experience. Diagnostic angiography was performed with either 4F or 6F diagnostic catheters; the size of the catheter used in each patient was predetermined by the day of the month. Patients undergoing 4F and 6F diagnostic angiography were ambulated after 4 and 6 hours, respectively. The following technical parameters were recorded by the operator: ease of introducer sheath insertion, ease of coronary intubation, ease of injection, coronary opacification, collateral flow demonstration, and overall assessment. Adverse events were recorded in all patients and included minor bleeding, major bleeding (necessitating blood transfusion), minor hematoma, major hematoma, pseudo-aneurysm formation and arteriovenous fistula.

Results: The study group included 177 patients, of whom 91 were in the 4F arm and 86 in the 6F arm. Demographic and procedural data were similar in both groups. Seventy-seven percent of 6F and 50% of 4F procedures were evaluated as excellent (P < 0.05). This difference was attributed to easier intubation of the coronary ostium and contrast material injection, increased opacification of the coronary arteries, and demonstration of collateral flow with 6F catheters. Complications occurred in 22% of patients treated with 6F catheters and 10% of those treated with 4F catheters (P = 0.11). Of the 50 patients who switched from 4F to 6F 12% had complications. In patients undergoing diagnostic angiography, the complication rate was 10% vs. 27% (most of them minor) in the 4F and 6F groups, respectively (P < 0.05).
Conclusions: Patients catheterized with 4F have fewer complications compared with 6F diagnostic catheters even when ambulated earlier. Although 4F had a reduced quality compared to 6F angiographies, they were evaluated as satisfactory or excellent in quality 85% of the time. 4F catheters have a potential for reduced hospitalization stay and are a good option for primary catheterization in patients not anticipated to undergo coronary intervention

Objectives: To assess factors related to the learning curve of laparoscopic colorectal surgery, such as the number of operations performed, the type of procedures, major complications, and oncologic resections.

Methods: We evaluated the data of our first 100 elective laparoscopic colorectal operations performed during a 2 year period and compared the first 50 cases with the following 50.

Results: The mean age of the study population was 66 years and 49% were males. Indications included cancer, polyps, diverticular disease, Crohn’s disease, and others, in 50%, 23%, 13%, 7% and 7% respectively. Mean operative time was 170 minutes. One patient died (massive pulmonary embolism). Significant surgical complications occurred in 10 patients (10%). Hospital stay averaged 8 days. Comparison of the first 50 procedures with the next 50 revealed a significant decrease in major surgical complications (20% vs. 0%). Mean operative time decreased from 180 to 160 minutes and hospital stay from 8.6 to 7.2 days. There was no difference in conversion rate and mean number of harvested nodes in both groups. Residents performed 8% of the operations in the first 50 cases compared with 20% in the second 50 cases. Right colectomies had shorter operative times and fewer conversions.

Conclusions: There was a significant decrease in major complications after the first 50 laparoscopic colorectal procedures. Adequate oncologic resections may be achieved early in the learning curve. Right colectomies are less difficult to perform and are recommended as initial procedures.

Objectives: To assess the risk of microvascular complications associated with the metabolic syndrome in diabetes subjects.

Methods: The study group comprised 415 diabetic subjects attending a primary care clinic. The prevalence of microvascular complications was compared between 270 diabetic subjects with metabolic syndrome (NCEP-III criteria) and 145 diabetic patients without.

Results: We found that as a group, diabetic subjects with metabolic syndrome had significantly higher frequency of microvascular-related complications than diabetic subjects without the syndrome (46.6% and 26.8% respectively, P = 0.0005). These include microalbuminuria (41.5% vs. 23.9%, P = 0.013), neuropathy (10.4% vs. 7.5%, P = 0.38), retinopathy (9.6% vs. 4.1%, P = 0.046) and leg ulcers (7.9% vs. 2.8%, P = 0.044). After adjustment for age, gender, glycemic control, disease duration, lipid profile and blood pressure, metabolic syndrome was associated with a significantly higher risk of microvascular complications: odds ratio (95% confidence interval) for nephropathy 2.27 (1.53–3.34), neuropathy 1.77 (0.79–4.0), retinopathy 3.42 (1.2–9.87), and leg ulcers 3.57 (1.08–11.95).

Conclusions: In addition to hyperglycemia and disease duration, the metabolic syndrome is a significant risk factor for the development of microvascular complications in diabetic subjects.

Objectives: To analyze our 8 year experience using TEM[1] for the management of rectal cancer.

Methods: Local resection by TEM was performed in patients with benign tumors and early rectal cancer. In addition, selected patients with T2 and T3 rectal cancers who were either medically unfit or unwilling to undergo radical surgery were also treated with this modality. Radical surgery was offered to all patients with incomplete tumor excision by TEM.

Results: Overall, 116 TEM operations for rectal tumors were carried out between 1995 and 2003, including 74 patients with rectal adenomas and 42 patients with rectal carcinomas. Twenty-five patients had T1 tumors that were all successfully removed, with clear tumor margins, by TEM. Fourteen patients had T2 cancer and 3 of them (21%) required additional radical surgery due to incomplete excision. Local recurrence was observed in one patient with T2 cancer. There was no mortality. Major surgery, or radiotherapy-related complications requiring additional surgical intervention was needed in five patients with T2 cancer.

Conclusions: Local excision by TEM is a safe surgical procedure and should be offered to highly selected patients with early rectal cancer.

Objectives: To evaluate the outcome of this procedure and to compare the complication rate following circumcisions performed by ritual circumcisers and by physicians.

Methods: In 2001, of the 19,478 males born in four major medical centers in Israel 66 had circumcision-related complications. All the children were circumcised in non‑medical settings within the community. The patients were medically evaluated either urgently due to immediate complications or electively in outpatient clinics later on. Upon the initial assessment a detailed questionnaire was filled to obtain data regarding the procedure, the performer and the subsequent complications.

Results: All the circumcisions were performed during the early neonatal life, usually on day 8 of life (according to Jewish law). In 55 cases (83%) it was part of a ritual ceremony conducted by a ritual circumciser (Mohel), while in 11 babies (17%) physicians were involved. Acute bleeding after circumcision was encountered in 16 cases (24%), which required suturing in 8. In addition, we found two cases of wound infection and one case of partial amputation of glans penis in which the circumcision was performed by a ritual circumciser. Among the late complications, the most common was excess of skin in 38 cases (57%); 5 children (7.5%) had penile torsion and 4 children (6%) had shortages of skin, phimosis and inclusion cyst. The overall estimated complication rate of circumcision was 0.34%.

Conclusions: Complications of circumcision are rare in Israel and in most cases are mild and correctable. There appears to be no significant difference in the type of complications between medical and ritual circumcisions.

Background: The appearance of pericarditis following insertion of a permanent pacemaker is not widely acknowledged in the literature.

Objectives: To describe our experience with pericarditis following 395 permanent pacemaker implantations over 2 years.

Methods: We retrospectively reviewed the medical records of 395 consecutive patients in whom new pacing systems or pacemaker leads had been implanted over a 2 year period. We searched the records for pericarditis that developed within 1 month after pacemaker implantation according to the ICD-9 code. The incidence, clinical picture, response to treatment and relationship to lead design and location were studied.

Results: Eight cases (2%) of pericarditis following implantation were detected. Clinical manifestations in all patients were similar to those of post-pericardiotomy syndrome and included chest pain (n=7), friction rub (n=1), fever (n=2), fatigue (n=2), pleural effusion (n=2), new atrial fibrillation (n=2), elevated erythrocyte sedimentation rate (n=4) and echcardiographic evidence of pericardial effusion (n=8). All affected patients had undergone active fixation (screw-in) lead implantation in the atrial position. The incidence of pericarditis with screw-in atrial leads was 3% compared to 0% in other cases (P < 0.05).

Conclusions: Pericarditis is not uncommon following pacemaker implantation with active fixation atrial leads. Special attention should be paid to identifying pericardial complications following pacemaker implantation, especially when anticoagulant therapy is resumed or initiated. The use of passive fixation leads is likely to reduce the incidence of pericarditis but this issue should be further investigated.

Background: Cystoscopy, the principal means of diagnosis and surveillance of bladder tumors, is invasive and associated with unpleasant side effects

Objectives: To determine the early complications of rigid cystoscopy and the impact on patients' quality of life and sexual performance.

Methods: One hundred consecutive patients undergoing diagnostic rigid cystoscopy filled in questionnaires including anxiety and pain levels (0–5 visual analogue scale), adverse events, short-form health survey, International Prostate Symptom Score, and functional sexual performance. Questionnaires were administered before, immediately after, and 1, 2 days, 2 and 4 weeks following cystoscopy.

Results: The pre-cystoscopy anxiety level was 2.01. The average pain during the examination was 1.41. SF-36[1] score was not affected by cystoscopy. The subjective impact on patients' quality of life was 0.51. The mean IPSS[2] increased following cystoscopy (6.75 vs. 5.43, P = 0.001) and returned to baseline 2 weeks later. A decline in libido was reported by 55.6% (25/45) and 50% (3/6) of the sexually active men and women, respectively. Cystoscopy was associated with a decreased Erectile Dysfunction Intensity Score, from 15.6 to 9.26 during the first 2 weeks (P = 0.04). The overall complication rate was 15% and included urethrorrhagia and dysuria. None of the patients had fever or urinary retention and none was hospitalized. The complication rate was higher in patients with benign prostatic hyperplasia (24% vs. 9.7%, P = 0.001).

Conclusions: Rigid cystoscopy is well tolerated by most patients and has only a minor impact on quality of life. However, cystoscopy transiently impairs sexual performance and libido. The early complications are mild and correlate with a diagnosis of BPH[3].

Background: Previously reported results of total hip arthroplasty in patients younger than 30 years of age indicate a high complication rate and questionable durability.

Objectives: To estimate the results of THA[1] in extremely young patients.

Methods: We report the results of 69 THA procedures in 56 patients who were under the age of 30 at the time of surgery (mean age 23.23 ± 4.31 years) and were followed-up postoperatively for 2–23 years (mean 7.4 ± 3.79 years).

Results: Loosening of the cup (11/69) and early traumatic dislocation (5/69) accounted for the majority of complications.

Conclusion: The final average Harris hip scores of 90.59 ± 9.36 in these patients indicated that THA is a successful and durable treatment modality for young patients with disabling diseases affecting the hip joint. However, due to the likelihood of complications it should be used with caution in this patient group. Efforts should be made to diminish the complication rate.

Background: Developments in laparoscopic surgery have rendered it an efficient tool for many complex surgical procedures. In the last few years, laparoscopic adrenalectomy has become a more viable option for removal of adrenal pathology, with many surgeons preferring it to the conventional open technique.

Objectives: To describe the indications, technique, complications and follow-up of patients undergoing laparoscopic adrenalectomy in our department.

Methods: The hospital files of 30 patients who underwent the procedure were reviewed. There were 19 females and 11 males with a mean age of 45 years. Indications for surgery differed and included hypersecreting adenoma, pheochromocytoma, suspected malignancy, and incidentaloma.

Results: Of the 31 laparoscopic adrenalectomies performed, 11 were right, 18 were left, and 1 was bilateral. The conversion rate to an open procedure was 3%. The mean duration of procedure was 120 minutes. Only one patient required blood transfusion. Complications occurred in 20% of patients, all reversible. There was no mortality. Mean hospitalization duration was 3.4 days, and median follow-up 17 months. There were no late complications. All patients operated on for benign diseases are alive.

Conclusions: Laparoscopic adrenalectomy appears to be a useful tool for the treatment of a range of adrenal pathologies.

Patients with diabetes and/or insulin resistance syndrome are at increased risk for developing cardiovascular disease. The UKPDS raised a great debate about the relative importance of hyperglycemia in the development of cardiovascular disease. Recently, several epidemiologic studies have suggested that high postprandial blood glucose levels are associated with a significant risk for the development of cardiovascular disease as well as a grave prognosis for these patients during acute coronary events. In addition, a number of reports reinforce the thesis that postprandial hyperglycemia is a risk factor for mortality. Our review summarizes the current knowledge on the relation between blood glucose, insulin levels, and cardiovascular morbidity and mortality, relating these data to the new World Health Organization and American Diabetes Association classification of disturbed glucose metabolism.
