Objectives/hypothesis: Intraoperative neuromonitoring identifies recurrent laryngeal nerve (RLN) injury and gives prognostic information regarding postoperative glottic function. Loss of the neuromonitoring signal (LOS) signifies segmental type 1 or global type 2 RLN injury. This study aimed at identifying risk factors for RLN injury and determining vocal fold (VF) function initially and 6 months after definitive LOS.

Methods: A total of 288 cases of ISP were included, 229 men and 59 women. The AP of the day of diagnosis, of the 3 prior days and the monthly average was registered.
Introduction: The purpose of this study was to analyse the relationship between preoperative serum levels of vitamin D and postoperative hypocalcaemia after total thyroidectomy.
Material And Methods: A prospective observational study was conducted on 113 patients treated by total thyroidectomy due to benign disease. Preoperative vitamin D serum levels and postoperative albumin-corrected calcium and parathormone (PTH) levels were determined.
Since the initial report in 1992, laparoscopic adrenalectomy has proved substantial advantages over the conventional procedure in terms of decreased postoperative pain and hospital stay, allowing earlier return to normal activity. The technical details are in permanent evolution and the most widely accepted laparoscopic surgery for the adrenal gland is the transabdominal lateral approach. We hereby describe step by step the way we perform the lateral approach after 41 consecutive cases.

Patients And Methods: A prospective observational study was performed with 120 patients. Three determinations were made of PTH in blood: baseline, when the diseases gland was located, and 10 minutes after its extirpation.
Objective: To analyze the prognostic value of p53 protein as a marker of recurrence risk in each tumoral stage.
Patients And Method: A prospective study of a cohort of 288 patients who underwent surgery for colorectal adenocarcinoma was performed. Stage 1 of the tumor-node-metastasis (TNM) classification was found in 42 patients (14.
Background: The aim of the present study was to evaluate the value of serum Carcinoembryonic Antigen (CEA) and CA125 antigen assay for monitoring the activity of non-small cell lung cancer (NSCLC) after curative surgical resection.
Patients And Methods: Serum CEA and CA 125 were determined preoperatively and at every postoperative visit, in 113 patients with NSCLC (TNM stages I, II, IIIA). Both markers were assayed by magnetic particle enzyme immunoassay.
Objective: we report the case of a 36 years old man with a pancreatic cancer associated to a pancreas divisum presenting as acute and relapsing recurrent pancreatitis. The coexistence of intraductal carcinoma and pancreas divisum is uncommon as let us do analyze its clinical, radiological and therapeutical features.
Conclusions: 1.
Background: This study examined the prognostic information regarding the risk of postoperative tumor recurrence obtained by simultaneous determination of preoperative serum carcinoembryonic antigen (CEA) and immunohistochemical expression of p53 protein in tumor tissue from patients with colorectal carcinoma.
Methods: A retrospective study of 174 patients (AJCC/UICC Stages I, II and III) was conducted. Serum CEA levels were determined by an enzyme-linked immunoadsorbent assay.
Objective: To assess the clinical and biological significance of histological typing of colorectal carcinomas.
Patients And Methods: The retrospective analysis of 142 consecutive patients who underwent surgical resection of a mucinous (MC; n = 27; 19%) or a nonmucinous (nMC; n = 115; 81%) colorectal adenocarcinoma was carried out. The two groups were compared in terms of the clinical features, p53 gene expression (antiserum CM1), proliferating cell nuclear antigen (PCNA) labeling index, DNA ploidy (by flow cytometry), histopathological features, prognosis and recurrence rate.
Purpose: The study contained herein was undertaken to report the case of a patient with juvenile polyposis in whom multiple and rapid recurrence of mixed polyps, with progressive predominance of the adenomatous component, developed in a diverted ileoanal pouch.
Methods: The case of this patient with juvenile polyposis was reviewed. Despite regular surveillance and polypectomies, extensive and multiple recurrences of serrated polyps developed.
Purpose: The aim of this study was to assess the value of Hughes' pathogenic classification in the prognosis and management of perianal Crohn's disease (CD).
Patients And Methods: This classification differentiates between purely inflammatory lesions and their mechanical or septic complications, and defines the presence of ulceration (U), fistula (F) and stricture (S), which are assigned a score of 0, 1 or 2 according to the severity and associated conditions, proximal intestinal involvement and disease activity (A, P and D). Of a series of 96 patients with CD, 12 underwent 16 procedures involving anesthesia to treat symptomatic anal lesions.
Objective: To review the results of the analysis and quantification of the influence of medical factors on the morbidity and mortality associated with emergency surgery for colorectal cancer.
Patients And Methods: We analyze retrospectively the data for 51 patients who underwent emergency surgery: 34 (67%) to treat acute obstruction and 17 (33%) for perforation. The median follow-up period was 18.
Objective: To determine the predictive value of p53 nuclear overexpression in comparison with established prognostic pathological features in colorectal adenocarcinoma.
Patients And Methods: 61 patients operated on for cure between January 1989 an December 1991 were included. Expression of p53 protein was examined by immunohistochemistry in paraffin-embedded sections.

The relationship between survival after surgical resection of colorectal carcinoma, and perioperative blood transfusion was studied retrospectively. "Curative" surgery was performed in 164 cases of colorectal cancer--stages B and C--, 72 of them received red-cell concentrates perioperatively. Multiple regression analysis did not show any deleterious effect of blood transfusion on the survival of the surgically treated patients (P = 0.
