Parathyroid hormone decline 4 hours after total thyroidectomy accurately predicts hypocalcemia.

BACKGROUND: The level of parathyroid hormone (iPTH) serum has been controversial in the prediction of postthyroidectomy hypocalcemia. Analysis of the decrease between preoperative and postoperative iPTH levels should be more accurate. Therefore, the aim of our study was to prospectively establish the reliability of the iPTH decrease for early diagnosis of postoperative hypocalcemia and to identify the patients who are not at risk for hypocalcemia. METHODS: A prospective study of 137 consecutive patients who underwent total thyroidectomy was performed. Serum iPTH level was measured preoperatively and 4 hours postoperatively (iPTH(H4)). The sensitivity, specificity, and positive and negative predictive values for the iPTH(H4) and for the iPTH decline were estimated by confidence interval from thresholds determined by ROC curve analysis. RESULTS: Thirty-nine patients developed hypocalcemia (28.5%). Patients who developed hypocalcemia had a significantly lower iPTH(H4) and a significantly greater iPTH decrease (P < .001). The thresholds enabling prediction of hypocalcemia were 19.4 ng/L for iPTH(H4) and 68.5% for iPTH decline. Sensitivity, specificity, and positive and negative predictive values for iPTH(H4) were 84.6%, 92.9%, 82.5%, and 93.8% (overall accuracy, 90.5%). iPTH decline was more accurate to predict hypocalcemia (sensitivity, 97.4%; specificity, 95.9%; positive predictive values 90.5%; negative predictive values, 98.6%; and overall accuracy, 96.4%). CONCLUSION: The decrease in iPTH is more precise than the iPTH(H4) alone and can accurately predict hypocalcemia after total thyroidectomy. Patients with a decrease in iPTH less than 68.5% can be discharged at postoperative day one without any supplementation. Patients with iPTH decline more than 68.5% should be administered calcium and vitamin D supplementation before symptoms appear.

Resectable pancreatic metastasis of left thighbone leiomyosarcoma: case report and literature review.

INTRODUCTION: Metastases to the pancreas gland are uncommon, especially from leiomyosarcoma. We report a case of asymptomatic pancreatic metastasis resection of leiomyosarcoma. CASE REPORT: A 59-year-old patient was treated for thighbone leiomyosarcoma, with surgical resection and adjuvant radiotherapy. After 4 years of follow-up, although that patient was asymptomatic, a pancreatic metastasis was identified by CT and fine needle aspiration. Open left pancreatectomy was performed. DISCUSSION: We discuss diagnosis findings and interest in the surgical resection. Furthermore, we reviewed previously reported cases.

Emergency laparoscopic management of perforated sigmoid diverticulitis: a promising alternative to more radical procedures.

BACKGROUND: Classic emergency surgical management of complicated perforated sigmoid diverticulitis is based on the principle of a two-stage operation, with colon resection and temporary stoma (Hartmann's procedure). But the later second-stage operation can be technically difficult and can be associated with a significant morbidity rate. We argue that laparoscopy may be beneficial in such patients with peritonitis in terms of operative results and could facilitate later surgical management. STUDY DESIGN: We studied all consecutive patients with perforated sigmoid diverticulitis requiring emergency surgery between January 2000 and December 2004. RESULTS: Twenty-four patients underwent emergency laparoscopic management for perforated sigmoid diverticulitis. Nineteen patients (80%) were found to have a purulent or fecal diffuse peritonitis. No conversion and colostomy were necessary. The overall morbidity rate was 8%; 2 patients with pelvic abscesses required radiologic drainage. The median hospital stay was 12 days (range 7 to 35 days). Prophylactic sigmoid resection was performed by laparoscopy in all patients, with a conversion rate of 16%. CONCLUSIONS: Laparoscopic treatment of generalized peritonitis secondary to diverticulitis is feasible and safe and may be a promising alternative to more radical surgery in selected patients, avoiding fecal diversion and allowing a delayed elective laparoscopic sigmoid resection.

[A case of compressing serous cystadenoma with renal carcinoma]. / Cas d'un cystadénome séreux pancréatique compressif associé à un carcinome rénal.

Pancreas cystadenoma tumors represent 10 to 15% of all cystic lesions of the pancreas. These tumors are asymptomatic in around 30% of patients, serous adenoma being the most common. Malignancy should be suspected when cystadenoma is compressive. We report the case of a 72-year-old man with a compressive serous cystadenoma associated to renal carcinoma.

[Recurrent glucagonoma 20 years after surgical resection]. / Récidive ganglionnaire d'un glucagonome 20 ans après l'exérèse chirurgicale.

Glucagonoma is a rare islet alpha-cell pancreatic tumor. Patients usually present with necrolytic migratory erythema, diabetes mellitus, thromboembolism, and weight loss. Diagnosis is based on the presence of a pancreatic tumor in association with hyperglucagonemia. Tumor characterization is made by computed tomography and/or pancreatic endoscopic ultrasonic and indium-labeled octreo-scan. Surgery is the main component of the treatment, in some cases in association with chemotherapy. We report the case of a 72-year-old patient who developed a recurrent glucagonoma, 20 years after surgical resection.
