Retroperitoneal endometriosis in postmenopausal woman causing deep vein thrombosis: case report and review of the literature.

Endometriosis is an uncommon disease in postmenopausal women (PMW), ranging from 2% to 5% of cases, and it is very important to exclude neoplastic transformation of the endometrium. The authors would like to introduce the case of a 63-year-old overweight patient with abdominal pain associated to pain and swelling of the left inferior limb occurring for approximately six weeks. The CT X-ray of the abdomen revealed the presence of a retroperitoneal mass causing deep vein thrombosis because of extrinsic compression of the left iliac vein. Following removal of the pelvic masses with laparotomy, the histological exam revealed an endometriosis. The CT X-ray carried out after a month postoperatively revealed the root canal treatment of the left femoral vein with a considerable decrease of the thrombosis of homolateral external iliac veins. Despite the endometriosis, it is uncommon in women who have reached menopause and must be considered in the differential diagnosis of pelvic masses.

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.
