RESUMO
OBJECTIVE: To evaluate cfDNA as an indicator of pancreatitis severity. BACKGROUND: Acute pancreatitis severity scores have limited proficiency, and are complex and challenging to use clinically. Elevation of circulating cfDNA concentration has been shown to be associated with hospital length of stay (LOS) and mortality. METHODS: In a prospective study, cfDNA concentration was measured by a simple fluorometric test, at admission and for 2 consecutive days, in patients with acute biliary pancreatitis (ABP). Ranson and APACHE II scores were used as measures of pancreatitis severity. Hospital LOS and mortality were used as outcome measures. RESULTS: Seventy-eight patients were included. Patients with severe disease according to Ranson's Criteria (n = 24) had elevated median admission cfDNA compared to patients with mild disease (n = 54, 2252ng/ml vs 1228 ng/ml, P < 0.05 ). Admission cfDNA levels correlated with Ranson and APACHE II scores and markers of bile duct obstruction. LOS did not differ between patients with mild and severe disease according to Ranson and APACHE II scores. Patients with cfDNA at 24 hours concentrations above the cutoff value of healthy patients (>850 ng/ml) had a significantly longer LOS compared to those with normal cfDNA levels ( P < 0.001 ). CONCLUSIONS: cfDNA, measured by a rapid simple assay, proved a valuable early marker of severity in ABP with clear advantages for prediction of LOS over Ranson and APACHE II. Measurement of cfDNA has the potential to be an effective practical approach to predict the course of ABP and should be further evaluated in larger trials.

BACKGROUND: Single-incision laparoscopic surgery (SILS) was introduced to further the enhanced outcome of conventional multiport laparoscopy (CML). We compared their short- and long-term outcomes in colorectal surgery. MATERIALS AND METHODS: Retrospective review of patients who underwent elective laparoscopic colorectal surgery during 3-year period. Patients' data, surgery outcomes, and oncological results were compared. RESULTS: Sixty-one patients (33 male, 28 female), mean age 67.4 years, underwent laparoscopic colonic resections: 28 SILS and 33 CML. Twenty-three (37.7%) patients had previous abdominal surgery. There were 19 (31.2%) right, 9 (14.7%) left, and 2 (3.3%) total colectomies, 16 (26.2%) sigmoidectomies, 13 (21.3%) anterior and 2 (3.3%) abdominoperineal resections. Colonic malignancy was a main indication for the surgery in 51 (83.6%) patients. Mean surgery time and postoperative stay were 92.0 minutes and 9 days, respectively. Pathological examination revealed stage I colon cancer in 16 (32%), stage II in 22 (44%), stage III in 10 (20%), and stage IV in 2 (4%) patients. Mean number of retrieved lymph nodes was 19 ± 13.5. No differences were found between groups in demographic data, type of surgery, surgery time and hospital stay, pathological results and tumor staging, and disease-free and overall survivals. In the SILS group, placement of additional trocar was required in 7 (25%) and conversion in 3 (10.7%) cases compared with 1 (3%) case of conversion to formal laparotomy in the CML group. Overall postoperative morbidity was 16.4%. There was no mortality in both the groups. During the study period, 3 patients from the CML group had cancer recurrence. CONCLUSIONS: SILS is a feasible and safe technique compared with CML in terms of surgical and oncological outcomes.

BACKGROUND: Self-expanding metallic stents (SEMS) insertion is an alternative to emergency surgery in malignant colonic obstruction. However, the long-term oncological outcome of stents as a bridge to surgery is limited and controversial. OBJECTIVES: To determine the long-term oncological outcome of stents as a bridge to surgery. METHODS: Data of patients who underwent emergency surgery and endoscopic stent insertion as a bridge to surgery due to obstructing colon cancer at Soroka Medical Center during a 14 year period were collected retrospectively. Preoperative data, tumor staging, and oncological outcomes in terms of local recurrence, metastatic spread, and overall survival of the patients were compared. RESULTS: Sixty-four patients (56% female, mean age 72 years) were included in the study: 43 (67%) following emergency surgery, 21 stent inserted prior to surgery. A stent was inserted within 24-48 hours of hospital admission. The mean time between SEMS insertion and surgery was 15 days (range 0-30). Most of the patients had stage II (41%) and stage III (34%) colonic cancer. There was no difference in tumor staging and localization between groups. There was no significant difference in disease recurrence between SEMS and surgery groups, 24% and 32%, respectively. Disease-free survival rates were similar between the SEMS group (23.8%) and surgery group (22%). Four year and overall survival rates were 52.4% vs. 47.6%, 33.3% vs. 39.5%, respectively. CONCLUSIONS: SEMS as a bridge to surgery in patients with obstructing colon cancer provide an equivalent long-term oncological outcome to surgery alone.

We present a case of a 20-year-old female who was admitted to our department for an elective inguinal hernia repair. An oval-shaped mass was found in the hernia sac during the surgery that was suspected to be an ovary. Histological examination revealed testicular tissue. Further evaluation confirmed testicular feminization. She underwent laparoscopic orchiectomy and hernia repair from the contralateral side 3 months later.
