RESUMO
Background: The aim of our study was to assess how total intra-venous anaesthesia (TIVA) achieved by propofol and remifentanil continuous infusion could ensure proper success of the endobronchial laser therapy, in optimal conditions for the endoscopist, determining at the same time an adequate hypnosis and a good analgesia. Methods: We studied 50 patients (28M - 22F), ASA class I-IV, mean age 42 ± 32.5 years , subjected to laser endoscopy to repair tracheal stenosis. TIVA was performed in all patients, and spontaneous breathing was maintained. Results: 10.2% of patients experienced episodes of coughing during induction. The depth of the anaesthesia plan, monitored by BIS, was 55 ± 5. The awakening was fast in all patients, with an Aldrete score of 7.71 ± 1.14 at 1 minute and 9.31 ± 1.12 at 10 minutes. Conclusion: The results of this study allow us to state that the continuous infusion of propofol and remifentanil proved to be the gold standard in patients ASA I-II-III undergoing endobronchial laser therapy. The use of TIVA has also allowed to perform endoscopic intervention on patients who suffered from a significant decrease of both cardiac and respiratory functions.

Abstract: Catheter dislocation and fracture with migration of central venous lines have been reported in the International literature. Catheter fracture with consequent migration has been observed in 0.5-3.0% and may either be consequent to catheter removal or it can occur spontane-ously. Our case report concerns the migration of a Hickman catheter connected to a venous port to the right atrium in a 61-year old patient. A literature up-to-date has been performed to assess the risk of port-a-cath positioning. The position of catheter tip is considered critical for the risk of migration, that is greater as higher the tip localization respect to the carina. The aim of our study is to underline the critical role of X-ray to visualize the exact location of the catheter tip, regard-less of the approach used for catheter positioning.

AIM: The purpose of this study is to determine the anatomical aspects, mechanisms, risk factors and appropriate management of development of pneumothorax during a routine colonoscopy. CLINICAL CASE: We report a case of an accidental bowel wall injury during diagnostic colonoscopic with consequent pneumoperitoneum; this was followed by expansion of gas through diaphragmatic fenestration perhaps congenital, in right pleural cavity causing pneumothorax. DISCUSSION: Rarely, colonic perforation during colonoscopy can occur into the extraperitoneal space, thus leading to the passage and diffusion of air along the fascial planes and large vessels, possibly causing pneumoretroperitoneum, pneumomediastinum, pneumopericardium, pneumothorax, and subcutaneous emphysema. The combination of intraperitoneal and extraperitoneal perforation has also been reported. Pneumothorax following a colonoscopy sigmoid perforation is an extremely rare but severe and often lifethreatening complication. CONCLUSION: If the patient develops dyspnea and pneumoderma during or after this procedure, a chest radiogram or thoracoabdominal CT should be taken for diagnostic purposes. Urgent treatment, starting with chest tube insertion(s) and laparotomy or laparoscopy could be lifesaving.

Abdominal scar endometriosis, corresponding to the presence of an endometrial tissue near or inside an abdominal surgical incision, is a rare clinical event that can occur in women after gynecological or obstetric surgery. Generally, a triad consisting of underlying mass at the incision, cyclic menstrual scar pain, and history of previous gynecological or obstetric surgery leads to the preoperative diagnosis. In rare cases, the clinical presentation is atypical and the differential diagnosis with incarcerated incisional hernia, granuloma, abscess or other soft tissue tumors can be difficult. The authors describe the case of 39-year-old woman who underwent three previous cesarean sections, with a 20-week history of underlying palpable mass at the Pfannenstiel incision, associated to continuous pain. In this case, a surgical excision followed by the histology definitely clarified the diagnosis.

INTRODUCTION: Even if T4 is standard treatment for hypothyroidism after thyroidectomy, a treatment with T4 plus T3 has been proposed as an alternative reproducing carefully the physiology of the thyroid. We performed an observational study about the effects of the combined replacement therapy with T4 and T3 in patients who underwent total thyroidectomy. PATIENTS AND METHODS: Fifty thyroidectomized patients (not for cancer), in T4 replacement therapy, were included in the study. Such a therapy has been changed by administering T3 and T4 in proportion 1/16. Adverse effects, clinical parameters and general health perceptions (SF36 Questionnaire) have been considered at the time of enrollment (T0), after 30 days (T1) and after 60 days (T2). RESULTS: No differences in weight, cardiac frequency and blood pression have been found between T0 and T2. A not statistically significant reduction has been found in total cholesterol (3 mg/dL) and triglycerides (3.29 mg/dL) levels. A reduction of complaints referred by the patients at T0 has been revealed in T2: anxiety from 21 to 13 patients; headache from 22 to 13; tiredness from 17 to 8 (p<0.05); sleepiness from 25 to 15 (p<0.05). About the questionnaire, in the General Health Perception sub-score has been found a not significant increase of the parameter. DISCUSSION AND CONCLUSIONS: T4 replacement therapy is of proved efficacy, notwithstanding some complaints afflict a share of patients. To improve the quality of life of these patients, we consider relevant the reduction of complaints and the improvement of well-being and cognitive function obtained by the combined T4 and T3 treatment. Moreover, even if the production of T3 from T4 usually ensures euthyroidism in all tissues, contemporary pathologies and alterations determined by the oldness can disturb the enzymatic activity, which is the essential requirement of T4 therapy. These preliminary findings in a small group of patients encourage further studies on a larger patient population.

Colorectal carcinoma is the third most frequently diagnosed malignant neoplasm. Usually patients affected by this neoplasia belong to VI decade of life. However approximately 2-8% of tumors arise in patients with age under 40 years. Aim of the study was to analyse the results of surgical treatment of colorectal cancer in patients aged under forty. From January 1987 to December 2002, 46 patients under forty years with colorectal cancer underwent surgical procedure. No perioperative mortality was registered, and complications were evidenced in nine patients (20%). Actuarial five years survival was 33%, and overall mean survival was 53 months. Univariate and multivariate analyses identified as prognostic factors the tumor grade, Dukes' stage, nodal status, and length of symptoms.

Primary ureteral adenocarcinoma is an infrequent histological type of urinary neoplasm. Many authors consider intestinal metaplasia the pivotal event of the pathogenetic process, whether it occurs on a pre-existing urothelial carcinoma or on a normal urothelium. Diagnosis is essentially based on case history and clinical findings (hematuria and pain) and on diagnostic imaging. Treatment is surgical and the ideal procedure is nephroureterectomy with excision of a bladder margin adjacent to the ureteral opening and ispilateral para-aortoiliac lymphadenectomy. A 76-year-old man with primary adenocarcinoma of the ureter case is reported.

AIMS: An association between elevated serum gastrin levels and the presence of human colorectal cancer has been reported, and gastrin has been shown to stimulate the growth of experimentally induced colon neoplasia. The aim of this study was to determine the preoperative and postoperative concentrations of serum gastrin in 53 patients with colorectal cancer and to assess the correlation between gastrin levels and tumor characteristics and prognosis. MATERIALS AND METHODS: A prospective study was performed over a six-year period during which 53 patients received potentially curative surgery for colorectal cancer. The prognostic variables used for the analysis included age, sex, tumor site, stage and degree of differentiation, preoperative and postoperative serum values of carcinoembryonic antigen (CEA) and gastrin, cancer-related mortality, and survival. CEA and gastrin serum values were determined using radioimmunological methods. Follow-up was carried out with clinical and radiological tests. RESULTS: The mean preoperative gastrin concentration was 51.2+/-27.4 pg/mL (range 12-146). Significantly increased serum gastrin concentrations, which returned to normal after surgery, were detected only in patients with well-differentiated cancer (74.2+/-28.3 pg/mL; moderately differentiated, 52.1+/-23.8; poorly differentiated, 29.9+/-12.3, p=0.02). The prognosis was unrelated to serum gastrin level; instead, tumor stage, preoperative CEA value, and degree of differentiation affected patient survival. CONCLUSIONS: This study showed that the serum gastrin concentration is not an appropriate clinical oncogenic factor. Although occurring only in well-differentiated tumors, serum gastrin is unrelated to the prognosis of patients with colorectal cancer.

A retrospective chart review was performed utilizing the First Department of Surgery of the University of Rome "La Sapienza" Medical School database. Ninety-two women who underwent abdominal surgery between 1980 and 1993 for rectal cancer were identified. Data collected included demographics, history, intraoperative findings and complications, cancer histology and stage and follow up. Special attention was focused on intraoperative incidental gynecological findings and follow up. Twenty-two patients being previously submitted to hysterectomy and three with oral intake of hormones were dismitted from the study. Of the remaining 67 patients gynecological procedure was associated to rectal surgery because of a previously undiagnosed gynecological condition. No prophylactic oophorectomies were performed. At follow up 7 patients experienced further surgery for gynecologic disease. The necessity to offer these patients the benefit of a preoperative informed decision about adjunctive gynecologic surgery and indications for bilateral oophorectomy is discussed.

It was suggested that there are no stronger prognostic factors in gastric cancer than nodal involvement or depth of wall invasion. The present paper evaluated the influence of maximum tumor diameter (MTD) value, measured on fixed resected specimens, on the extent of disease progression and the outcome in gastric cancer patients. Clinicopathological data were retrospectively retrieved from records of 122 patients who underwent curative gastrectomy. The patients' MTD values were grouped as follows: MTD1, up to 26 mm; MTD2, between 26 and 50 mm; and MTD3, over 50 mm. The three groups evidenced significant differences with regard to 5 year survival (MTD1: 54%, MTD2: 31%, MTD3: 20%; p = 0.00027), furthermore they were significantly different with respect to the type of gastrectomy (p = 0.021), depth wall invasion (p = 0.000), lymphatic microinvasion (p = 0.014), perineural microinvasion (p = 0.017), stromal reaction (p = 0.025), and stage (p = 0.035). ROC curve analysis individuated a best accurate MTD threshold value for nodal involvement of 32 mm (sensitivity = 56.6%; specificity = 60.9%; positive predictive value = 52.6%; negative predictive value = 64.6%). The logistic regression analysis suggested that the depth of wall invasion was the only independent variable associated with MTD value (p = 0.0005). Multivariate analysis showed that independent prognostic risk factors were sex (p < 0.0025), number of involved nodes (p < 0.001) and MTD (p < 0.001). In conclusion, the maximum tumor diameter value of gastric cancer may be a factor with greater prognostic implications than previously believed.

Accidental or voluntary foreign bodies ingestion is a frequent reported event in emergency departments. Complication, foreign body shape related are not often observed and, once occurred, just few a cases need an open surgery approach, about 1%. The Authors report the case of a young woman with pica admitted to their Department in an emergency setting for acute intestinal obstruction due to the ingestion of not specified amount of elastics, which required an open surgery operation.

The Authors reviewed the complications, and outcomes in a consecutives series of 97 patients undergoing pancreaticoduodenectomy. The clinical leak rate in this series was 21.8%. There was a difference in the pancreatic leak rate in those patients who underwent pancreatic ductal closure or end to end pancreaticojejunal invagination compared with end to side pancreaticojejunal anastomosis. The postoperative complication rate was 41.8% and the most common complications were pancreatic fistula. 9 deaths occurred in hospital or within 30 days from operation. Univariate and multivariate analysis revealed that operative technique, the pathological status of the pancreatic remnant, and mayor complications were the significant risk factors for the development of pancreatic anastomotic leak. In the 2000s pancreatic leak remains a potentially lethal problem. After pancreaticoduodenectomy, pancreatic remnant management by end to side pancreaticojejunostomy appeared safe in low-risk patients. Morbidity was greatest after pancreatic duct closure without anastomosis.

A retrospective study on 41 patients with primary stoma creation after low anterior resection of the rectum was made. Among the 41 patients 24 had a loop colostomy (Group A) and 17 had a loop ileostomy (Group B). The two groups were well matched for each of the data analysed and there was no significant difference in the rate of complications related to stomas creation and closure. In this study the Authors suggest that loop ileostomy is the best procedure to electively defunctionate colorectal anastomoses.

A retrospective study was made on 18 male patients with breast carcinoma treated at the Department of Surgery "Pietro Valdoni" of the University "La Sapienza" of Rome, Medical School. Demographics, pathology, stages, and treatment were determined from clinical reports. All patients but one underwent modified radical mastectomy. The length of follow up averaged 57.5 months. Five years actuarial survival rate was 62%. In the current study the Authors suggest that the clinical, prognostic and treatment features of breast carcinoma in men are similar to those reported in literature for post-menopausal women.

A retrospective study on 18 patients with cecal volvulus surgically treated was made. Demographics and clinical data, as well as treatment were determined from clinical reports. The operative procedures employed were cecostomy (56%), cecopexy (22%) and right colectomy (22%). The length of follow up averaged 63 months and there was one recurrence. The Authors suggest that cecostomy should be employed in patients with viable bowel, and resection should be limited to cases with gangrene.

Myelolipoma is an uncommon benign tumor, composed of an admixture of adipose tissue and hematopoietic cells, usually discovered within the adrenal glands. Extra-adrenal myelolipomas are rare and approximately half of the reported cases were presacral. We report a case of an asymptomatic presacral myelolipoma measuring 9x8x7 cm, incidentally found in a 71-year-old woman with a stenosing colon cancer. Ultrasonography, computed tomography and magnetic resonance imaging of the presacral mass evidenced a well circumscribed tumor with heterogeneous features due to a nonuniform composition. Surgical excision of the mass was performed.

Pilonidal disease (PD) is a common chronic disorder of the sacrococcygeal region afflecting young people. Despite several methods for treating PD have been described, the management remains controversial. Recent reports have advocated different surgical approaches such as open or closed technique, but recurrence plagues all forms of therapy. We conducted this case review to evaluate the validity of an outpatient closed technique in the treatment of chronic pilonidal disease. Between January 1997 and July 1999, 65 consecutive patients with quiescent chronic PD were electively treated by surgical excision of the cyst and primary closure. There were 47 men (72%) and 18 women (28%) in this study. Patients ranged in age from 14 to 47 years, the average age being 21 years. The median healing time was 8 days and the median time to return to full work was 20 days (range 10-25). Infection and recurrence rates were 1.5% and 4.6% respectively. There was no correlation among recurrence rate, postoperative infection, or prior surgery. Cyst excision and primary closure is a safe, low cost operation with a very high long-term success rate and a negligible rate of complications. It can successfully be performed under local anaesthesia in an outpatient facility.

BACKGROUND: Preservation of the inferior mesenteric artery (IMA) and consequential blood flow to the rectum would reduce the risk of leakage of a colorectal anastomosis. METHODS: One hundred and sixty-three patients undergoing left colectomy for complicated diverticular disease of the colon were randomly placed into two groups: A, n = 86; and B, n = 77. In group A, the integrity of the IMA was preserved by artery skeletization (IMAS); in group B, the IMA was divided at its origin. Variables recorded included duration of the surgical procedure, need for blood transfusion, length of hospital stay, operative mortality and morbidity, staple-ring disruption, and radiologic and clinical leakage. Anastomotic stenosis and recurrence of diverticular disease were noted. RESULTS: Surgical time was superior in the IMAS group. Radiologic and clinical leakages were significantly higher in group B (P = 0.02, P = 0.03, respectively). In group A a significant lower number of staple-ring disruptions was observed, evolving into clinical dehiscence. CONCLUSION: Preserving the natural blood supply to the rectum and the ensuing use of a healthy well-nourished rectal stump are suggested as the main aspects of IMAS in preventing and healing leakage of colorectal anastomosis.

OBJECTIVE: To evaluate the correlation between biliary-enteric surgical drainage and the late development of cholangiocarcinoma of the biliary tract. SUMMARY BACKGROUND DATA: In patients with biliary-enteric drainage, reflux of intestinal contents into the bile duct may occur and cause cholangitis, which is regarded as the most serious complication of these procedures. Lithiasis of the biliary tract and a previous biliary-enteric anastomosis have both been suggested to favor the late onset of cholangiocarcinoma. METHODS: Consecutive patients (n = 1,003) undergoing three different procedures of biliary-enteric anastomosis (transduodenal sphincteroplasty, choledochoduodenostomy, and hepaticojejunostomy) between 1967 and 1997 were included in this study. The postoperative clinical course and long-term outcome were evaluated by a retrospective review of the hospital records and follow-up. Mean follow-up was 129.6 months. RESULTS: Fifty-five (5.5%) cases of primary bile duct cancer were found among the 1,003 patients at intervals of 132 to 218 months from biliary-enteric anastomosis. The incidence of cholangiocarcinoma in the three groups was 5.8% in transduodenal sphincteroplasty patients, 7.6% in choledochoduodenostomy patients, and 1.9% in hepaticojejunostomy patients. The incidence of malignancy related to the different underlying diagnosis was 5.9%, 7.2%, and 1.9% in patients with choledocholithiasis, sphincter of Oddi stenosis, and postoperative benign stricture, respectively. Although only one patient who developed cholangiocarcinoma had previous concurrent lithiasis of the biliary tract, 40 patients had experienced mostly severe, recurrent cholangitis. No case of malignancy occurred in patients scored as having no cholangitis in the early and long-term postoperative outcome. Univariate and multivariate analyses have shown the presence of cholangitis as the only factor affecting the incidence of cholangiocarcinoma. CONCLUSIONS: Chronic inflammatory changes consequent to biliary-enteric drainage should be closely monitored for the late development of biliary tract malignancies.
