THE VOLUME OF SOLITARY PARATHYROID ADENOMA IS RELATED TO PREOPERATIVE PTH AND 25OH-D3, BUT NOT TO CALCIUM LEVELS.

PURPOSE: To correlate the volume of parathyroid adenomas with the hormonal and metabolic profile at patients diagnosed with primary hyperparathyroidism (pHPTH). PATIENTS AND METHODS: Cross-sectional multicentric study, enrolling 52 patients with pHPTH from two medical institutions. Serum calcium and PTH were evaluated in all patients before surgery, whereas 25OHD3 was measured only in the 33 patients recruited form one medical unit. The volume of parathyroid adenoma was measured by using the formula of a rotating ellipsoid. RESULTS: We observed a significant correlation of the volume of parathyroid adenomas with PTH at patients from the two units and in the whole group (p < 0.0001), but not with serum calcium (p = 0.494). Twenty-five out of the 33 patients at whom 25OHD3 was measured had levels in the range of deficiency. 25OHD3 was not correlated with PTH or calcium levels, but was negatively correlated to the adenoma volume and positively to the PTH/volume ratio (p = 0.041 and p = 0.048, respectively). CONCLUSIONS: The volume of parathyroid adenoma seems to be related to preoperative PTH and 25OHD3, but not to calcium level. Vitamin D deficiency is frequently found at patients with pHPTH and may contribute to particular disease profiles, including larger parathyroid adenomas.

[Pancreaticoduodenectomy for pancreatic head cancer, 54 cases]. / Duodenopancreatectomia cefalica in cancerul de cap de pancreas--consideratii asupra 54 cazuri.

UNLABELLED: Pancreatic cancer has an increase rate in western countries. From the first pancreaticoduodenectomy (PD) performed by Kausch in 1909, the value of the resection in the treatment of pancreatic head cancer was disputed. AIM: To assess the PD with or without pylorus preservation as surgical treatment for pancreatic cancer. METHODS: Retrospective review of the clinical records of patients undergoing PD for pancreatic cancer. RESULTS: From January 1995 till December 2005, in the First and Third Surgical Units, "St. Spiridon" University Hospital Iasi, Romania, were performed 137 PD. From these, 54 cases were histologic diagnosed with pancreatic cancer; 23 cases underwent pylorus preserving pancreatico-duodenectomy (PPPD) and 31 patients, classical Whipple procedure (PDW). Mean age was 59.07 +/- 1.42 years old (26-75 years old), and male to female ratio was 29 to 25. Jaundice was presented in 51 cases (94.4%), abdominal pain at 39 patients (72.2%) and Curvoisier-Terrier sign at 37 cases (68.7%). Fever was observe only in 4 cases (7.4%). Other biological and imaging parameters (e.g. main diameter of the biliary duct, tumor and wirsung ) were also discussed, but no significant difference was found between PPPD and PDW. Pancreatico-jejunostomy was performed in 41 cases (28 during the PDW and 13 in PPPD) and 13 pancreatico-gastrostomy (3 during PDW and 10 during PPPD). Mean operating time and mean blood loss in the PDW group were 358.22 +/- 10.53 minutes and 587.74 +/- 60.87 mL. After PPPD, these figures were 326.08 +/- 15.04 minutes and 571.74 +/- 90.50 mL, but no significant difference was noted. Delayed Gastric Emptying (DGE) was presented at 15 patients: 8 in PPPD group and 7 in PDW group (p=0.322). Postoperative morbidity rate (excluding DGE) was 33.33% (8 cases in PDW group and 10 in PPPD group). Pancreatic leak has a rate of 5.55% (3 cases--one in PPPD group vs two in PDW group), biliary leak has a rate of 12.96% (4 in PPPD group vs 3 in PDW group)and duodeno-jejunal anastomotic fistula appeared in one cases (PPPD). Acute postoperative pancreatitis is presented in one case (PPPD group) and postoperative hemorrhage appeared in 4 cases (2 in PPPD and 2 after PDW). Hospital stay was 19.91 +/- 2.28 days in PPPD group vs 18.87 +/- 2.24 days in PDW group (p = 0.751). Postoperative mortality rate was 5.5% (one case after PPD and 3 cases after PDW). Histological exam diagnosed ductal pancreatic adenocarcinoma in 51 cases (94.44%). Mean long-term survival rate was 20.98 months (10.52-31.45 months; 95 CI) and no difference was revealed between PPPD and PDW (log rank test - p = 0.796). CONCLUSION: PD should be performed for any pancreatic tumor even without preoperative histologic confirmation. The results after PPPD (postoperative morbidity and mortality, long-term survival) are similar to that following conventional Whipple procedure, if the principles of viable and tumor free margins are observed.

[The role of fine needle aspiration biopsy in differentiated thyroid carcinoma]. / Utilitatea punctiei cu ac fin in carcinoamele tiroidiene bine diferentiate.

UNLABELLED: Fine needle aspiration biopsy (FNAB) in evaluation of nodular goiter generated a true revolution. It is generally assumed that the use of FNAB reduces the number of surgical procedures by 50%, while doubles the proportion of carcinoma in surgically treated patients. The aim of the study was to demonstrate the utility of FNAB in preoperative diagnosis of thyroid carcinoma. MATERIAL AND METHOD: We have investigated 3240 patients with nodular goiter by FNAB (MGG stain and morphometrical analysis), followed by morphological examination in those who underwent surgery. RESULTS: Globally, FNAB had a good sensitivity (77%) and specificity (95%), which made an accuracy of 92%, proving its diagnostic value. In follicular carcinoma (FC), where the cytological diagnostic cannot be certain, morphometry helped the diagnostic: mean cells diameter was significantly higher (p < 0.001) in FC (9.5 mm) vs. thyroid adenoma (8.6 mm). CONCLUSION: With good statistical value, FNAB remain a useful preoperative diagnostic method.

[Pancreaticoduodenectomy with or without pylorus preservation: a retrospective analysis of 137 patients]. / Duodenopancreatectomia cefalica cu sau fara prezervarea pilorului: analiza retrospectiva a 137 pacienti.

OBJECTIVE: We performed a retrospective study to assess the postoperative results, long-term survival and quality of life after pylorus preserving pancreaticoduodenectomy (PPPD) versus standard Whipple pancreaticoduodenectomy (WPD). METHODS: A retrospective study was performed in a nonselected series of 137 patients who were operated in the Surgical Clinics of "St. Spiridon" University Hospital Iasi, Romania, from January 1st, 1995 till December 31, 2005. Demographics, preoperative and intraoperative data, as well as postoperative morbidity, mortality and follow-up were analyzed. Quality of life, after to at least six months after discharge, was also studied. RESULTS: There were no significant differences noted in demographics data. Jaundice was more frequent in the PPPD group as for WPD patients (p=0.047). For the most patients the digestive reconstruction after resection were performed as in Child technique: the first anastomosis was pancreaticojejunostomy (end-to-end or end-to-side), the second anastomosis was hepaticojejunostomy (end-to-side) and the last anastomosis was gastrojejunostomy end-to-side (duodenojejunostomy in PPPD group). For 31 cases a pancreatico-gastrostomy were performed. We also noted 14 cases with pancreatico-gastrostomy and duodenojejunostomy end-to-end, and a Roux jejunal loop for 3 patients with previous gastrectomy and gastrojejunostomy (Reichel-Polya). The operating time was shorter in the PPPD group as in WPD (p < 10-3), but the mean blood loss was the same. Postoperative morbidity rate was 46.8% in PPPD group vs 39.2% in WPD (p > 0.05), but the reintervention rate was significant higher in PPPD group (30.6% vs 15%; p = 0.027). We also noted no significant differences of Delayed Gastric Emptying, postoperative mortality rate (14.5% in PPPD group vs 10.1% in WPD group) and mean survival time (42.42 months (24.94 - 59.89; 95% CI) in PPPD group vs 46.78 months (28.07 - 61.50; 95% CI) in WPD group; log rank test p = 0.643). Pathological exam diagnosed a malignancy in 109 cases (54 cases with pancreatic cancer); we noted chronic pancreatitis in 22 cases. Quality of life was also the same in the two groups. CONCLUSIONS: PPPD and WPD were associated with comparable results, but, there is a tendency of increase rate of postoperative morbidity and mortality for PPPD patients. We also noted that postoperative quality of life is the same for both procedures.

[Rare caecal pseudotumours]. / Pseudotumora cecala de cauza rara.

Among the rarely caecal pseudotumours are those caused by a coagulation disorder. The clinical course of caecal pseudotumours is highly variable. Most patients are diagnosed with acute appendicitis, but the real diagnosis is confirmed after laboratory investigation and histopathologic exam. Our patient presented the symptoms of an inferior digestive bleeding. The persistence of the clinical symptoms and the haematological degradation determined the surgical intervention. Intraoperative were found two caecal tumours. The hystological exam, biochemical and haematological analysis worked up the final diagnosis: a caecal pseudotumour in the context of Antithrombin III deficiency.

[Spontaneous esophageal rupture in three patients]. / Ruptura spontana de esofag la trei pacienti.

Boerhaave's syndrome represents the most severe perforation of the gastrointestinal tract. The typical clinical presentation is by a sudden onset of pain after a vomiting effort on the background of an alimentary and alcoholic abuse. It usually associates the cervicomediastinal emphysema, altogether forming the Mackler triad. The atypical presentation and the rarity of this entity usually lead to the delay in diagnosis in 50% of the cases. The diagnosis requires native and hydrosoluble contrast radiological examination which may reveal, altogether with the esomedistinal or esopleural fistula, pneumomediastinum, cervical subcutaneous emphysema, pleural effusion or hydropneumothorax. The early diagnosis and surgical treatment in the first 24 hours after the perforation offer the best chances for survival. We present and analyze the cases of 3 patients with spontaneous esophageal rupture with their different evolution and the diagnostic and treatment steps in each case.

[Differentiated thyroid cancer--staging and prognostic systems]. / Cancerul tiroidian diferentiat stadializare si sisteme de scor prognostic.

Differentiated thyroid cancer (DTC), including papillary and follicular carcinoma with histological variants, has an excellent prognosis; nevertheless a subset of these tumours is clinically aggressive and, in some patients, fatal. Treatment of DTC remains controversial, regarding the extent of primary surgical resection, the need for lymph node dissection and the role of postoperative radioactive iodine ablation. In addition to the widely accepted TNM classification, recognition of significant risk factors and developing of staging systems, such as AMES, AGES, MACIS, MSKCC and NTCTCS, has helped to identify the patients with a potential aggressive course of the disease and high risk of recurrence. This has allowed the development of a rational and selective approach to therapy, thus, avoiding excessive treatment and subsequent morbidity without compromising the oncological outcome.

[Laparotomy in the treatment of severe intraperitoneal infections]. / Laparostomia în tratamentul infectiilor grave intraperitoneale.

A retrospective clinical study was carried out on a group of 18 patients with severe intraperitoneal infections due to various causes. The decision to use laparotomy was supported by the severity of sepsis (APACHE II score varied from 14 to 30), highly septic peritoneal fluid, the features of peritonitis, patients with impaired immunity. Open packing was realized with a Dacron mesh sutured to the fascial margins, associated with multiple peritoneal drainage in all cases. Postoperative mortality was 50%, mainly to rapid evolution of septic shock, unresponsive to intensive care support. Secondary suture was performed after granulation of the wound, on the day 14-21 postoperatively followed at 3-4 months by definitive repair of the abdominal wall in 2 cases. Laparotomy proved to be an efficient treatment in severe peritonitis, that should be used prior to irreversible phases of septic shock.

[Multiple perforated, poorly differentiated carcinomas of the small bowel]. / Carcinoame slab diferentiate sincrone perforate de intestin subtire.

The small bowel malignant tumors represent a rare pathology; in their diagnosis an important role is played by the clinical suspicion in front of non-specific symptoms. However, the therapeutic decision must not be delayed by excessive explorations, but it should be permanently adapted to the patient's condition; the operative exploration has the advantage of making an accurate diagnosis. The authors present the case of a patient admitted in emergency with the suspicion of a generalized peritonitis from a perforated peptic ulcer and who was subsequently diagnosed with multiple perforated small bowel malignant tumors. The patient's history offers data that could be interpreted in the context of the intraoperative diagnosis. This is the first reported case of multiple perforated poorly differentiated carcinomas of the small intestines.

[Upper gastrointestinal bleeding from a perforated gastric ulcer into left atrium, after esophageal resection and gastric replacement of the esophagus]. / Hemoragie digestiva superioara prin ulcer peptic pe grefon gastric intratoracic, perforat în atriul stâng.

Using the stomach as a substitution after oesophagectomy is the most common method. The stomach brought intra thoracic it seems that maintains or regains its capacity to secrete hydrochloric acid and therefore can develop specific conditions, despite total denervation following bilateral troncular vagotomy. We are presenting the case of a young patient who was operated on for a corrosive esophagitis. She had an oesophagectomy and a transposition of the stomach to the posterior mediastinum and anastomosed to the cervical esophagus. She presents with upper gastro-intestinal bleeding from gastric ulcer penetrating into the left atrium.
