Background: Following an intestinal anastomotic leak, stoma creation may be the safest approach. However, this method may be challenging and cause significant morbidity. In selected cases, a T drain approach can be beneficial and a stoma can be avoided.

Objectives: To present one group's experience with a T drain approach for anastomotic leaks.

Methods: Data on patients who underwent emergent re-laparotomy following gastrointestinal anastomotic leaks were retrieved retrospectively and assessed with a new intra-operative leak severity score.

Results: Of 1684 gastrointestinal surgeries performed from 2014 to 2018, 41 (2.4%) cases of anastomotic leaks were taken for re-laparotomy. Cases included different sites and etiologies. Twelve patients were treated with a T-tube drain inserted through the leak site, 18 had a stoma taken out, 6 re-anastomosis, 4 were treated with an Endosponge, and one primary repair with a proximal ileostomy was conducted. T drain approach was successful in 11 of 12 patients (92%) with full recovery. One patient did not improve and underwent reoperation with resection and re-anastomosis. A severity score of anastomotic integrity is provided to help surgeons in decision making.

Conclusions: A T drain approach can be an optimal solution in selected cases following an intestinal anastomotic leak. When the leak is limited, the remaining anastomosis is intact and the abdominal environment allows it, a T drain can be used and a stoma can be avoided.

Despite advances in therapeutic modalities, especially with biologic treatments, the number of hospitalizations due to complications for Crohn's disease did not decrease. We examined the prevalence and possible predictive factors of hospitalizations in Crohn's disease. A systematic literature search was conducted until 31 October 2018. Relevant studies were screened according to established protocol. Retrospective cohort studies describing hospitalizations of Crohn's disease patients were included. Meta-analysis was performed by using comprehensive meta-analysis software. Pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated for the number of patients hospitalized. Twelve studies published before 31 March 2018 fulfilled the inclusion criteria and were comprised of 23 data-sets and included 4421 patients from six countries. A funnel plot demonstrates a moderate publication bias. We reported the event rates for the number of patients hospitalized, in a follow-up survey of 20,987 patient-years, and for the patients who underwent surgery in a follow-up of 5061 patient-years, with ORs of 0.233 with 95%CI 0.227–0.239, and 0.124 with 95%CI 0.114–0.135 (P < 0.001), respectively. Thus, when collecting the data from 12 cohort studies we found that hospitalization takes place in 23.3% of the patients, and operation in 12.4% along their disease duration. Patients with Crohn's disease may be hospitalized due to exacerbation of their inflammatory disease, because of non-inflammatory disease (such as fistula or stricture), or due to medical complications. The goal of therapy should be to keep the Crohn's disease patients in their natural environment and out of the hospital and to prevent surgery as much as possible.

Background: The MitraClip procedure is becoming an acceptable alternative for high-risk patients with mitral regurgitation (MR) due to functional (FMR) or degenerative (DMR) disease and suitable mitral anatomy.

Objectives: To evaluate the results of MitraClip at our institute in carefully selected patients.

Methods: We conducted a retrospective analysis of medical records and echocardiography data from January 2012 to December 2017.

Results: A total of 39 MitraClip procedures in 37 patients (aged 75 ± 12 years, 9 women) was performed. Twenty-four patients presented with FMR, 12 with DMR, and 1 with combined pathology. One-day post-procedure MR was moderate to low in 86.1% of patients, with immediate device success in 88.8%. MR at 1 year was moderate to low in 79% at 1 year. Survival at 1 year was 86% and at 2 years 69.4%. Peri-procedural (< 1 week) death and MitraClip failure occurred in one and three patients, respectively. New York Heart Association score improved to class 1 or 2 in 37% of patients at 1 year vs. one patient at baseline. Post-procedural systolic pulmonary pressure was reduced from 53 (range 48–65) to 43 (range 36–52) mmHg at 1 month with a subsequent plateau at follow-up, to 41 (34–57) mmHg at 6 months, and to 47 (38–50) at 12 months.

Conclusions: MitraClip in severe MR resulted in modest improvement in functional status and pulmonary pressure with a small risk of immediate procedural complications. Outcomes are encouraging considering the natural course of MR and the risks of surgical intervention.

Background: Temporal trends in the incidence of inflammatory bowel disease (IBD) in the Arab and Jewish populations in Israel have been poorly described.

Objectives: To compare the annual incidence and prevalence rates of Crohn's disease (CD) and ulcerative colitis (UC) in the Arab and Jewish populations in Israel between the years 2003 and 2008.

Methods: We applied a common case identification algorithm to the Clalit Health Services database to both determine trends in age-adjusted incidence and prevalence rates for IBD in both populations during this period and estimate the burden of IBD in Israel.

Results: The incidence of CD in the Arab population increased from 3.1/100,000 in 2003 to 10.6/100,000 person-years in 2008, compared with a decrease in the Jewish population from 14.3/100,000 to 11.7/100,000 person-years for the same period. The incidence of UC in the Arab population increased from 4.1/100,000 in 2003 to 5.0/100,000 person-years in 2008, a low but stable rate, compared with a decrease from 16.4/100,000 to 9.5/100,000 person-years for the same time period in the Jewish population. The prevalence of both diseases increased due to the accumulation of incident cases but remained much lower among Arabs.

Conclusions: Understanding the factors underlying the differences in incidence and prevalence of IBD in the Jewish and Arab populations may shed light on the genetic and environmental factors associated with these diseases.

Background: Pneumonia is a major cause of morbidity and mortality in burn patients with inhalation injuries. An increased risk of pneumonia has been demonstrated in trauma and burn patients urgently intubated in the field vs. emergency departments (EDs).

Objectives: To compare intubation setting (field vs. ED) and subsequent development of pneumonia in burn patients and to evaluate the indication for urgent intubation outside the hospital setting.

Methods: A retrospective medical records review was conducted on all intubated patients presenting with thermal (study group, 118 patients) or trauma (control group A, 74 patients) injuries and admitted to the intensive care unit of a level I trauma and burn center at a single institution during a 15 year period. Control group B (50 patients) included non-intubated facial burn patients hospitalized in the plastic surgery department.

Results: Field intubation was less frequent (37% field vs. 63% ED), although it was more frequent in larger burns (total body surface area > 50%; 43% field vs. 27% ED). More field intubated patients developed pneumonia during hospitalization (65% field vs. 36% ED [burns]; 81% field vs. 45% ED [multi-trauma]; 2% non-intubated, P < 0.05), with a significantly higher all-cause mortality (49% field vs. 24% ED, P < 0.05) and dramatically lower rates of extubation within 3 days (7% field vs. 27% ED, P < 0.05).

Conclusions: Field intubation is associated with a higher risk of subsequent development of pneumonia in burn and multi-trauma patients and should be applied with caution, only when airway patency is at immediate risk.

Background: Mortality and decrease in function after hip fracture are significantly related to patient factors including age, gender, co-morbidities, and mental status. Several studies demonstrated ethnic disparities in incidence, mortality, and functional outcome after hip fractures in the United States.

Objectives: To assess the relationship between ethnicity and hip fracture incidence and outcomes of mortality, functional change, and perioperative complications in the Israeli population.

Methods: We reviewed our institutional hip fracture registry for all patients from 2014–2015. Patients with incomplete data, < 60 years of age, or pathologic and periprosthetic fractures were excluded. Our study comprised 693 patients. Ethnicity was based on country of birth. Specifically, for those born in Israel, the nationality of either Jewish or Arab was further dichotomized. Perioperative complications, mortality, and mobility status at 1 year follow-up were recorded. The ethnicities of 27,130 patients admitted to the medicine and surgical wards during the same time interval served as a control group for the hip fracture cohort.

Results: Immigrants from Europe and America had the highest incidence of hip fractures. Fracture types varied in incidence in groups with 70% of extracapsular hip fractures occurring in Arabs and immigrants from Eastern countries, compared to 60% in immigrants from Western countries and the former Soviet Union. Mortality, perioperative complications, and mobility at 1 year were similar in all ethnic groups.

Conclusion: Our study demonstrated significant differences in incidence and fracture characteristic among ethnicities, but no difference in patient outcome. These findings differed from the available North American studies.

Background: Family physicians and internal medicine specialists play an essential role in treating cancer patients. Modern technological advances in radiotherapy are not widely appreciated by primary care physicians. Bone metastases are a frequent complication of cancer. Palliative radiation therapy, as a component of modern advances in radiation treatments, should not subject normal bodily structures to excessive doses of irradiation. The sacrum is a common destination site for bone metastases, yet its concave shape along with its proximity to the rectum, intestines, and femoral heads creates treatment-planning challenges.

Objectives: To investigated whether the volumetric modulated arc therapy (VMAT) technique is preferable to more conventional radiation strategies.

Methods: The study comprised 22 patients with sacral metastases who were consecutively treated between 2013 and 2014. Two plans were generated for the comparison: three-dimensional (3D) and VMAT.

Results: The planning target volume (PTV) coverage of the sacrum was identical in VMAT and 3D planning. The median values for the rectal dose for 3D and VMAT were 11.34 ± 5.14 Gy and 7.7 ± 2.76 Gy, respectively. Distal sacral involvement (S4 and S5) was observed in only 2 of 22 cases, while the upper pole of the rectum ended at the level above S3 in just 3 cases.

Conclusions: Radiation therapy continues to be an integral component of the palliative armamentarium against painful metastases. Radiation oncologist, in conjunction with referral physicians, can tailor treatment plans to reflect the needs of a given patient.

Background: Unicuspid and bicuspid aortic valve (BAV) are congenital cardiac anomalies associated with valvular dysfunction and aortopathies occurring at a young age.

Objectives: To evaluate our experience with aortic valve repair (AVr) in patients with bicuspid or unicuspid aortic valves.

Methods: Eighty patients with BAV or unicuspid aortic valve (UAV) underwent AVr. Mean patient age was 42 ± 14 years and 94% were male. Surgical technique included: aortic root replacement with or without cusp repair in 43 patients (53%), replacement of the ascending aorta at the height of the sino-tubular junction with or without cusp repair in 15 patients (19%), and isolated cusp repair in 22 patients (28%).

Results: The anatomical structure of the aortic valve was bicuspid in 68 (85%) and unicuspid in 12 patients (15%). Survival rate was 100% at 5 years of follow-up. Eleven patients (13.7%) underwent reoperation, 8 of whom presented with recurrent symptomatic aortic insufficiency (AI). Late echocardiography in the remaining 69 patients revealed mild AI in 63 patients, moderate recurrent AI in 4, and severe recurrent AI in 2. Relief from recurrent severe AI or reoperations was significantly lower in patients who underwent cusp repair compared with those who did not (P = 0.05). Furthermore, the use of pericardial patch augmentation for the repair was a predictor for recurrence (P = 0.05).

Conclusions: AVr in patients with BAV or UAV is a safe procedure with low morbidity and mortality rates. The use of a pericardial patch augmentation was associated with higher repair failure.

Background: A dental appliance for obstructive sleep apnea (OSA) is recommended for patients who cannot adjust to continuous positive airway pressure (CPAP) treatments.



Objectives: To describe patients with extremely severe OSA who were successfully treated with a dental appliance and to compare their characteristics with the relevant literature to identify clinical features associated with a good outcome.



Methods: The clinical, management, and outcome data of three patients with an apnea-hypopnea index (AHI) of > 80 who showed clinical improvement following treatment with a dental appliance were collected retrospectively from sleep laboratory reports in Israel over a period of 3 years. 



Results: The patients included one man and two women, aged 33, 56, and 61 years, respectively. The diagnosis of OSA was based on clinical examination and polysomnography. AHI values at presentation were 83, 81, and 84, respectively. Treatment with a dental appliance (Herbst® or MDSA®) was proposed due to patient noncompliance with CPAP. Follow-up polysomnography with the dental appliance revealed a reduction in the AHI to 1.7, 10.7, and 11, respectively. All patients had supine OSA and a retrognathic mandible, both of which have been found to be associated with a good prognosis for treatment with a dental appliance.



Conclusions: Dental appliances may be considered an appropriate second-choice option to treat severe OSA in patients who are noncompliant with CPAP. This study helps physicians identify patients with extremely severe OSA who are suitable for dental appliance treatment. Well-designed large-scale studies are needed to reach definitive conclusions. 

Background: Outcomes of patients with acute ST-elevation myocardial infarction (STEMI) are strongly correlated to the time interval from hospital entry to primary percutaneous coronary intervention (PPCI). Current guidelines recommend a door to balloon time of < 90 minutes. 

Objectives: To reduce the time from hospital admission to PPCI and to increase the proportion of patients treated within 90 minutes. 

Methods: In March 2013 the authors launched a seven-component intervention program: 

1. Direct patient evacuation by out-of-hospital emergency medical services to the coronary intensive care unit or catheterization laboratory


2. Education program for the emergency department staff


3. Dissemination of information regarding the urgency of the PPCI decision


4. Activation of the catheterization team by a single phone call


5. Reimbursement for transportation costs to on-call staff who use their own cars


6. Improvement in the quality of medical records


7. Investigation of failed cases and feedback 

Results: During the 14 months prior to the intervention, initiation of catheterization occurred within 90 minutes of hospital arrival in 88/133 patients(65%); during the 18 months following the start of the intervention, the rate was 181/200 (90%) (P < 0.01). The respective mean/median times to treatment were 126/67 minutes and 52/47 minutes (P < 0.01). Intervention also resulted in shortening of the time interval from hospital entry to PPCI on nights and weekends. 

Conclusions: Following implementation of a comprehensive intervention, the time from hospital admission to PPCI of STEMI patients shortened significantly, as did the proportion of patients treated within 90 minutes of hospital arrival. 

 

Background: Transcatheter tricuspid valve-in-valve implantation (TVIV) is an attractive yet under-explored alternative to redo valve surgery. 

Objectives: To report the multicenter TVIV experience in Israel.

Methods: We approached multiple centers and collected data regarding seven TVIV cases. 

Results: The study group comprised seven participants: five females and two males, with a mean age of 63 ± 12 years and EuroSCORE-II 13.6 ± 3.3%. Follow-up ranged from 3 to 21 months (mean 8 ± 6 months). All presented with advanced heart failure. The indication for valve intervention was a predominant tricuspid stenosis in three patients, significant tricuspid regurgitation in one and a mixture in three. Six procedures were conducted via a transfemoral approach and one by transatrial access. The Edwards SAPIENTM XT valve was used in four cases and the SAPIENTM 3 in three. Without pre-stenting/rapid pacing, all participants underwent successful valve implantation. Mean transvalvular gradient decreased from 11 ± 3 mmHg to 6 ± 3 mmHg (P = 0.003) and regurgitation decreased from moderate/severe (in four cases) to none/trace (in six of the seven cases). One patient remained severely symptomatic and died 3.5 months after the implantation. All others achieved a functional capacity improvement and amelioration of symptoms soon after the implantation, which persisted during follow-up. 

Conclusions: TVIV may be a safe and effective strategy to treat carefully selected patients with degenerated bioprosthetic tricuspid valve at high operative risk. 

 

Background: Strong evidence suggests that in order to prevent irreversible testicular damage surgical correction (orchidopexy) for undescended testis (UDT) should be performed before the age of 1 year. 

Objectives: To evaluate whether orchidopexy is delayed in our medical system, and if so, to explore the pattern of referral for orchidopexy as a possible contributing factor in such delays. 

Methods: We conducted a retrospective chart review of all children who underwent orchidopexy for UDT between 2003 and 2013 in our institution. We collected data on the age at surgery and the child's health insurance plan. We also surveyed pediatricians from around the country regarding their pattern of UDT patient referral to a pediatric urologist or surgeon for surgical correction.

Results: A total of 813 children underwent orchidopexy in our institute during the study period. The median age at surgery was 1.49 years (range 0.5–13). Only 11% of the children underwent surgery under the age of 1 year, and 53% between the ages of 1 and 2 years. These findings were consistent throughout the years, with no difference between the four health insurance plans. Sixty-three pediatricians who participated in the survey reported that they referred children to surgery at a median age of 1 year (range 0.5–3 years).

Conclusions: Our results demonstrate delayed orchidopexy in our medical system. There is a need to improve awareness for early specialist consultation in order to facilitate earlier surgery and better care.
