Background: Major efforts are being directed at the early diagnosis of breast cancer. The diagnosis rate of non-palpable tumors is steadily growing as a result of increased screening by mammography. In most patients with non-palpable lesions, percutaneous image-guided biopsies have replaced wire localization with surgical excision for obtaining tissue diagnosis. In recent years the Israel Ministry of Health initiated a mammograpy screening program. Percutaneous image-guided biopsies have also become widely available.

Objective: To assess the impact of these changes on breast cancer surgical treatment in our hospital.

Methods: The charts of 483 patients operated on in our department for primary breast carcinoma during the years 1997 to mid-2001 were reviewed. Data on the mode of diagnosis, tumor stage, resection margins, and number and types of operations were recorded and analyzed. The term non-palpable tumors relates to tumors necessitating wire localization for surgical excision.

Results: The percentage of patients diagnosed with non-palpable tumors rose from 16.2% in 1997 to 47.4% in 2001, with an average size of 2.6 cm for palpable and 1.7 cm for non-palpable tumors. The rate of preoperative diagnosis for non-palpable tumors rose from 6.2% in 1997 to 96.4% in 2001. The rate of involved or very close margins was reduced by 73% in the patient group diagnosed preoperatively as compared to those without a preoperative diagnosis (10.6% vs. 39.4%). Finally, the percentage of patients who had two operations fell from 56.2% in 1997 to 11.1% in 2001.

Conclusions: The mammography screening program in Jerusalem in 1997–2001 was effective in increasing the relative percentage of non-palpable breast cancers with reduced tumor size at diagnosis. The improved availability of preoperative tissue diagnosis in these patients reduced the number of surgical procedures needed.

Background: Reperfusion practices have changed markedly over the last few years with the introduction of primary percutaneous coronary intervention. This technique has gained growing popularity in Israel, but little published data are available regarding the delays to primary PCI[1] in real life in this country.

Objectives: To examine temporal trends in time to reperfusion achieved in a large tertiary center over 6 years.

Results: Between 1997 and 2002, 1,031 patients were admitted to our hospital with ST elevation myocardial infarction. Of these, 62% underwent thrombolysis and 38% primary PCI. The proportion of patients referred for primary PCI increased steadily, from 14% in 1997 to 68% in 2002. Door to treatment time among patients referred for thrombolysis or primary PCI was 54 ± 42 and 117 ± 77 minutes, respectively (P < 0.00001). The door to needle time in patients given thrombolysis remained virtually unchanged during the study period at around 54 minutes. In contrast, the door to balloon time has progressively and substantially decreased, from 175 ± 164 minutes in 1997 to 96 ± 52 minutes in 2002.

Conclusions: There is a steady increase in the proportion of patients referred for primary PCI than for thrombolysis. The door to needle delay in patients given thrombolysis substantially exceeds the recommended time. The door to balloon time has declined considerably but still slightly exceeds the recommended time. Given the inherent delay between initiation of lysis and arterial recanalization, it appears from our experience that PCI does not substantially delay arterial reperfusion as compared to thrombolysis. Efforts should continue to minimize delays to reperfusion therapy.

Background: The mainstay of therapy for acute cholecystitis is cholecystectomy, which has a mortality of 14–30% in high risk patients. An alternative approach in patients suffering from acute cholecystitis with contraindications to emergency surgery is percutaneous cholecystostomy.

Objective: To evaluate the efficacy and safety of percutaneous cholecystostomy as the initial treatment of acute cholecystitis in high risk patients.

Methods: Eighty consecutive patients (42 men, 38 women) underwent ultrasound-guided percutaneous cholecystostomy over a 5 year period. Sixty-five patients suffered from acute calculous cholecystitis, 4 patients had acalculous cholecystitis, and 11 patients had sepsis of unknown origin.

Results: Sixty-eight patients improved after the percutaneous gallbladder drainage, 10 patients died from co-morbid disease and 2 patients died from biliary peritonitis. During a 1 year follow-up, 32 of the patients underwent interval cholecystectomy, 4 additional patients died from a co-morbid disease, 18 patients did not suffer from any gallbladder symptoms, and 14 were lost to follow-up.

Conclusions: Percutaneous cholecystostomy is an effective contribution to the treatment of acute cholecystitis in high risk patients.

Background: Current clinical guidelines restrict catheterization laboratory activity without on-site surgical backup. Recent improvements in technical equipment and pharmacologic adjunctive therapy increase the safety margins of diagnostic and therapeutic cardiac catheterization.

Objective: To analyze the reasons for urgent cardiac surgery and mortality in the different phases of our laboratory’s activity in the last 11 years, and examine the impact of the new interventional and therapeutic modalities on the current need for on-site cardiac surgical backup.

Methods: We retrospectively reviewed the mortality and need for urgent cardiac surgery (up to 12 hours post-catheterization) through five phases of our laboratory’s activity: a) diagnostic (years 1989–2000), b) valvuloplasties and other non-coronary interventions (1990–2000), c) percutaneous-only balloon angioplasty (1992–1994), d) coronary stenting (1994–2000), and e) use of IIb/IIIa antagonists and thienopiridine drugs (1996–2000).

Results: Forty-eight patients (0.45%) required urgent cardiac surgery during phase 1, of whom 40 (83%) had acute coronary syndromes with left main coronary artery stenosis or the equivalent, and 8 (17%) had mechanical complications of acute myocardial infarction. Two patients died (0.02%) during diagnostic procedures. In phase 2, eight patients (2.9%) were referred for urgent cardiac surgery due to either cardiac tamponade or severe mitral regurgitation, and two patients (0.7%) died. The combined need for urgent surgery and mortality was significantly lower in phase 4 plus 5 as compared to phase 3 (3% vs. 0.85%, P = 0.006).

Conclusion: In the current era using coronary stents and potent antithrombotic drugs, after gaining experience and crossing the learning curve limits, complex cardiac therapeutic interventions can safely be performed without on-site surgical backup.
 

Background: The mortality rate for cholecystectomy for acute cholecystitis in the elderly is 10% in low risk patients and increases threefold in high risk patients. Ultrasound-guided percutaneous transhepatic cholecystostomy may serve as a rapid and relatively safe tool to relieve symptoms of sepsis and decrease gallbladder distension.

Objective: To determine the safety and effectiveness of PTC[1] in the treatment of acute cholecystitis in elderly debilitated high risk patients.

Methods: The study sample included 10 patients aged 63–88 (mean 77.6 years) with clinical and sonographic signs of acute cholecystitis for more than 48 hours (fever, white blood cells > 12,000/mm³, positive Murphy sign and distended gallbladder) who underwent ultrasound guided PTC. All had severe underlying disease (coronary heart disease, renal failure, chronic obstructive pulmonary disease, and others) that places them at high risk for surgical intervention.

Results: Eight patients showed rapid regression of the clinical symptoms following PTC drainage. One patient, with bacterial endocarditis, was febrile for 5 days after catheter insertion, but with rapid resolution of the biliary colic and sepsis. One patient died from perforation of the gallbladder and small bowel. PTC catheters were withdrawn 3–25 days after the procedure, and the patients remained free of biliary symptoms. Two patients underwent successful elective cholecystectomy 3 weeks later.

Conclusion: PTC may be a safe and effective treatment for high risk elderly patients with acute cholecystitis. It can be followed by elective cholecystectomy if the underlying condition improves, as soon as the patient stabilizes and no sepsis is present, or by conservative management in high surgical-risk patients.

Background: Small bowel obstruction with perforation is an unusual and rare complication of bezoars.

Objective: To describe our use of emergency laparotomy to treat intestinal obstruction caused by bizarre bezoars.

Conclusions: An aggressive surgical approach to intestinal obstruction in the pediatric disabled or mentally retarded population is recommended.
