Which differences do elderly patients present in single-stage treatment for cholecysto-choledocholithiasis?

Patients with symptomatic gallstones present common bile duct stones in approximately 10% of cases. It is possible to resolve both gallbladder and bile duct stones with a single procedure. The aim of this study is to determine the effectiveness of a single stage procedure for gallbladder and bile duct stones in the elderly patients and to expose the differences between the various techniques. From January 2008 to December 2013, we treated 1540 patients with gallbladder stones. In 152 cases, we also found bile duct stones. 150 of these were treated in a single stage procedure. We divided our patients into 2 groups: Group A was younger than 65 (104 patients); Group B was 65 or older (46 patients). We retrospectively compared sex, ASA score, conversion rate, success rate, post-operative complications, hospital stay, and treatment method. We had no intra-operative mortality. 1 patient in Group B, heart condition (ASA 4), died with multiple organ failure (MOF) 10 days after his operation. ASA score: 3.5 ± 0.5 in A vs 2 ± 0.9 in B (P 0.001), post-operative complications 6% in A vs 18.1% in B (P 0.0325) and hospital stay 4.1 ± 2.3 in A vs 9.5 ± 5.5 in B (P 0.0001) were significantly higher in Group B. No differences were found in term of success rate: 94% in A vs 90% in B (P 0.4944). The procedure used to obtain the clearance of the bile duct showed a different success rate across the two groups: for the patients under 65 years old, trans-cystic clearance (TC-CBDE) was successful in 90% of cases, and only 51% for those older than 65, where we had to recall 49% for laparo-endoscopic rendez-vous (RV-IOERC) (P 0.0014). In conclusion, single stage treatment is safe and effective also to elderly patients. The methods used in patients being younger than 65 years old is what appeared to be significantly different.

Early biomarkers of hypocalcemia following total thyroidectomy.

Hypocalcemia is the most frequent major complication following total thyroidectomy (TT), delaying timely hospital demission. We prospectively evaluated the diagnostic utility of parathyroid hormone (PTH) measured one hour after TT and the delta (post-minus pre-surgery) PTH in order to determine which biomarker best predicted post-surgery hypocalcemia. Ninety-six consecutive patients, with either plurinodular goiter, Graves' disease or cervico-mediastinal goiter (22 (23%) men and 74 (77%) women, mean age 48.5 ± 15.2 and 47.9 ± 13.2 years, respectively), scheduled to undergo TT were enrolled. PTH was measured prior and one hour after surgery. Delta PTH was defined as one-hour post-surgery values minus pre-surgery PTH level. Hypocalcemia was defined as a calcemia under 8.0 mg/dL. Receiver operating characteristic (ROC) analysis was used to evaluate the Area Under Curve (AUC), sensibility and specificity of the two biomarkers for the occurrence of hypocalcemia. Forty-nine (51%) patients presented biochemical values under the cut-off but only 17 (18%) had clinical symptoms. Both variables yielded statistically significant AUC (PTH one-hour post surgery: 0.654; p = 0.0403; 95%CI: 0.519-0.773 and delta PTH: 0.659; p = 0.0263; 95%CI: 0.527-0.776). Although comparison of the two ROC curves did not yield significant differences, delta PTH yielded a better sensitivity and PTH one-hour post-TT yielded a marginally better specificity (sensitivity of 50% and 87% and specificity of 76% and 67% for cut-offs of <39.8 pg/dl and <54.5 pg/dl, respectively). Both biomarkers have similar diagnostic accuracy for hypocalcemia, and can be used to indicate when supplemental therapy should be implemented in order to favor a timely discharge.

Thyroid surgery with harmonic focus, ligasure precise and conventional technique: a retrospective case-matched study.

BACKGROUND: New surgical technologies have been introduced in thyroid surgery, to achieve vessel sealing and hemostasis. The aim of the study was to examine their effectiveness and compare the outcome of total thyroidectomy using the Harmonic Focus™, the LigaSure® Precise and the conventional technique of suture ligation. METHODS: A retrospective case-matched study of all total thyroidectomies between October 2008 through May 2010 was conducted. Patients (n=240) underwent total thyroidectomy using three different methods; the Harmonic Focus™ (Group F, n=80), the LigaSure Precise® (Group L, n=80) and the conventional technique of suture ligation (Group C, n=80). RESULTS: No significant differences were identified between the 3 groups in terms of demographics, thyroid gland weight, pathologic diagnosis, preoperative and postoperative calcium levels, postoperative complications, duration of hospital stay, and final outcome. The operative time was shorter with Harmonic Focus® by about 15%. Statistical analysis revealed a statistically significant difference between operations with F (62.7±14.1 minutes) and C (72.7±13.6minutes) with (p=0.019). CONCLUSION: Both devices were safe and efficient. A significant reduction of the operative time was found with Harmonic Focus® compared to the other two techniques with no statistically significant differences in postoperative complications in the 3 groups.
