Cholangitis prevention in endoscopic Klatskin tumor palliation: air cholangiography technique.

INTRODUCTION: Endoscopic biliary drainage is the treatment of choice for inoperable hilar cholangiocarcinoma (so-called Klatskin tumor). Cholangitis is the main complication post-endoscopic retrograde cholangiopancreatography (ERCP) in Klatskin patients, specially when medium contrast is injected into biliary tree that could not be subsequently drained. Bacterial cholangitis is the principal cause of mortality in these patients. The aim of this study is to analyze cholangitis rate resulting from the use of air versus iodine contrast to obtain cholangiography during ERCP. METHODS: In 9 years, 188 inoperable Klatskin patients were recruited and divided into two groups: iodine (A) or air (B) contrast cholangiography, respectively. We used air or iodine contrast to obtain cholangiography before hilar stricture stenting. We retrospectively compared these data in both groups. RESULTS: The group B had a significant lower rate of cholangitis than group A in Bismuth type II (p < 0.05), in Bismuth type III (p < 0.05), and in the Bismuth type IV population (p < 0.05). CONCLUSION: The air contrast cholangiography is a safe and effective method, and it appears justified as a routine procedure to prevent or reduce the risk of post-ERCP cholangitis, specially in Klatskin patients (p < 0.005).

[Role of intragastric air filled ballon (Heliosphere Bag) in severe obesity. Personal experience]. / Ruolo del palloncino intragastrico riempito ad aria (Heliosphere Bag) nel trattamento dell'obesità grave. Esperienza personale.

INTRODUCTION: Obesity leads to serious health consequences, therefore many strategies are recommended for preventing or curing this emerging problem. Treatments are various: diet, physical activity, psychotherapy, drugs and bariatric surgery. In order to try to improve the tolerance of intragastric balloons, a new device inflated with air to improve weight loss was developed in 2004 (Heliosphere BAG). We report our personal experience about this tool. MATERIAL AND METHODS: Between January 2005 and December 2007, in our unit, 50 intragastric air filled insertion were performed under analgosedation and endoscopic control. The balloon was removed (24 hours) in two patients (4%) for acute intolerance. In other 2 patients (4%) the balloon was easily removed after 5 months because of premature desuflation, radiologically confirmed. The remnant 46 balloons were removed after six months. We evaluated efficacy, tolerance and the safety of this procedure. RESULTS: Forty one women and 9 men, with a mean age of 38.1 years (range 18-62), mean basal BMI of 39.8 (range 28-64) were included, after providing informed consent. Weight and BMI loss were evaluated on all patients. BMI decreased 5.9%, weight loss was 16.8 kg. Tolerance was very good, limited only to some dispeptic symptoms during the first 2 days after insertion. No serious technical problems were noted at balloon insertion. Balloon removal was very simple after correct desuflation after the conclusion of learning curve (10 procedures). DISCUSSION: The aim to treat obesity before bariatric surgery is based on reduction of bariatric surgical risks, general surgical risks and the prevalence of cardiovascular diseases, diabetes, musculoskeletal disorders and some cancers. CONCLUSIONS: The intragastric air filled balloon showed an acceptable profile of efficacy, good tolerance and improvement of comorbidities after 6 months.

Secondary aortoduodenal fistula.

Aorto-duodenal fistulae (ADF) are the most frequent aorto-enteric fistulae (80%), presenting with upper gastrointestinal bleeding. We report the first case of a man with a secondary aorto-duodenal fistula presenting with a history of persistent occlusive syndrome. A 59-year old man who underwent an aortic-bi-femoral bypass 5 years ago, presented with dyspepsia and biliary vomiting. Computed tomography scan showed in the third duodenal segment the presence of inflammatory tissue with air bubbles between the duodenum and prosthesis, adherent to the duodenum. The patient was submitted to surgery, during which the prosthesis was detached from the duodenum, the intestine failed to close and a gastro-jejunal anastomosis was performed. The post-operative course was simple, secondary ADF was a complication (0.3%-2%) of aortic surgery. Mechanical erosion of the prosthetic material into the bowel was due to the lack of interposed retroperitoneal tissue or the excessive pulsation of redundantly placed grafts or septic procedures. The third or fourth duodenal segment was most frequently involved. Diagnosis of ADF was difficult. Surgical treatment is always recommended by explorative laparotomy. ADF must be suspected whenever a patient with aortic prosthesis has digestive bleeding or unexplained obstructive syndrome. Rarely the clinical picture of ADF is subtle presenting as an obstructive syndrome and in these cases the principal goal is to effectively relieve the mechanical bowel obstruction.

Permanent stenting in "unextractable" common bile duct stones in high risk patients. A prospective randomized study comparing two different stents.

BACKGROUND: Endoscopic sphincterotomy (ES) and stone extraction is the treatment of choice for bile duct stones. Therefore, if ES and conventional stone extraction fail, further treatment is mandatory. Insertion of a biliary endoprosthesis is an effective option. MATERIALS AND METHODS: We treated 30 high-risk patients (17 women and 13 men, mean age 82 years) affected by difficult common bile duct stones. The patients were randomly assigned preoperatively using closed envelopes (blind randomization) into two groups to receive insertion of polyethylene or hydrophilic hydromer-coated polyurethane stent, respectively. Follow-up was achieved by contacting referring physicians and patient's relatives. RESULTS: Biliary drainage was established in all patients. Early minor complications occurred in 28%. In all these patients, the stent was a definitive measure. Median follow-up was 38 months. Late complications occurred in 34%. Cholangitis was the most frequent. During follow up, 11 patients died, two as result of a biliary-related cause. No statistically significant difference was observed on different stents patency. CONCLUSION: Endoprosthesis insertion as a permanent therapy is an effective alternative to surgery or dissolution therapy. Therefore, biliary stenting should preferably be restricted to high-risk patients unfit for operative treatment and with a short life expectancy.

[Complication of flexible fiberoptic bronchoscopy. Literature review]. / Le complicanze della fibrobroncoscopia. Revisione della letteratura.

INTRODUCTION: Fiberoptic bronchoscopy is the gold standard to study and eventually treat tracheo-bronchial pathology. Performance of fiberoptic bronchoscopy enhances diagnostic precision and has not well documentated risks for the patients. This review examines the international literature of the last 30 yrs about the indication, complications and their prevention during bronchoscopy. MATERIALS AND METHODS: We reviewed by Internet 50 scientific articles, 23 of those were reporting or citing other experiences. We included as metasearch criteria "flexible", "fiberoptic", "bronchoscopy" and "complications" from 1974 to 2006, and as exclusions terms "pediatry", "pregnancy" and "urgency/emergency". Thus, we reported for every complication the incidence range, the characteristics and the indications for the bronchoscopy. DISCUSSION: On 107969 bronchoscopies, the incidence of complication of local anaesthesia was 0.3-0.5%; hypoxiaemia 0.2-21%; arrhythmia 1-10%; post-biopsy bleeding 0.12-7.5%; pneumothorax or pneumomediastinum 1-6%; fever 0.9-2.5%; death 0.1-0.2%. The majority of these complications were not life threatening. CONCLUSIONS: Flexible bronchoscopy is an extremely safe procedure as long as some basic precautions are taken: complications incidence may be reduced by accurate patient selection, correct indication to bronchoscopy with an adequate anaesthesia or analgosedation and the correct endoscope. Is safe and useful virtual bronchoscopy in selected cases. Equipe cooperation and the responsibility of performing endoscopes are basilar. The gain of informed consensus is imperative before the bronchoscopy.

[Endoscopic treatment of a "gastric outlet syndrome" after Mason Vertical Banded Gastroplasty. Case report]. / Trattamento endoscopico di un caso di "gastric outlet syndrome" dopo gastroplastica verticale sec. Mason. Caso clinico.

INTRODUCTION: Mason's Vertical Banded Gastroplasty (VBG) is characterized by peculiar complications, related to surgical pitfalls, from "outlet syndrome" (5%) to complete outlet obstruction (3%), passing to reflux oesophagitis (45%), that require redo. We report a case of "outlet syndrome" treated by operative endoscopy with success. MATERIALS AND METHODS: 40 yrs male, operated by VBG 2 years ago for morbid obesity (BMI > 40). After surgery, initial ponderal decrement as attended. Since about 2 months the patients reports epigastralgia and retrosternal pyrosis; since 10 days incoercibile vomiting. The EGDS visualized distal oesophagitis (Los Angeles C), mucosal prolapse of superior pouch leading to outlet obstruction and scalloping of Kerkring's fold in second part of duodenum. The patient was submitted to multiple elastic ligature of exuberant gastric mucosa with multiband ligator and indication to oral therapy with PPI and procinetics drugs at the dismission. RESULTS: after 30 days, at EGDS, oesophagitis is regressed to Los Angeles B stage, the outlet of pouch is patent and the transit is objectively regular. At oesophago-gastric radiologic control with gastrographin, the transit was satisfing. At 1 year follow-up the patient has a regular weight, no vomiting and is wellbeing and use irregularly PPI Follow-up EGDS confirmed the stabilization of endoscopic picture and the total regression of oesophagitis. CONCLUSIONS: the endoscopic elastic ligature of mucosal gastric prolapse with multiband after VBG, if confirmed and validated by randomized and prospective trials on a big sample of people, will constitute a valid alternative to surgical treatment of this rare complication.

Trocar-related abdominal wall bleeding in 200 patients after laparoscopic cholecistectomy: Personal experience.

AIM: To determine the complications and incidence of the first and second access-related vascular injuries induced by videolaparoscopic cholecistectomy. METHODS: We retrospectively reviewed vascular injuries in 200 consecutive patients who underwent videolaparoscopic cholecistectomy from 2003 to 2005. One hundred and one patients with placement of radial expanding trocars were assigned into group A and 99 patients with placement of pyramidal tipped trocars into group B. All the patients were submitted to open access according to Hasson for the first trocar. RESULTS: Bleeding did not occur at the intraoperative cannula-site in group A. However, it occurred at the intraoperative cannula-site of 7 patients (7.1%) in group B, with a statistically significant difference (P < 0.01). No mortality was registered. More vascular lesions were found in group B. CONCLUSION: The advantage of Hasson technique is that peritoneal cavity access is gained under direct vision, preventing most severe injuries. The open technique with radial expanding trocars is recommended for secure access to the abdominal cavity in videolaparoscopy. Great care should be taken to avoid major complications and understanding the abdominal wall anatomy is important for reducing bleeding during or after s placement of trocars.

[Emergency thyroidectomy for primitive lymphoma of thyroid. Case report and diagnostic and therapeutic guidelines]. / Tiroidectomia in urgenza per linfoma primitivo della tiroide. Descrizione di un caso ed indicazioni diagnostico-terapeutiche.

OBJECTIVE: A case of acute wheezing causing primitive thyroid lymphoma observed ay the Operative Unit of General and Thoracic Surgery of the University "P Giaccone" of Palermo, Italy, is reported. EXPERIMENTAL DESIGN: Diagnostic, clinical and prognostic indication, evaluation of effectveness of radical surgical treatment and follow-up. INTERVENTION: Emergency radical surgical treatment (debulking) and surgical tracheostomy (tracheal infiltration). RESULTS: Complete recovery with "restitutio ad integrum". No relapse were recorded ad short follow-up. CONCLUSIONS: Total thyroidectomy in front of uncertain cytology with the suspect of Hashimoto' s treatment or acute wheezing or localized neoplasm (IE or IIE) is feasible and rationale. If possible, this treatment of choice must observe standard technique, with visualization and respect of four parathyroid glands and recurrent laryngeal nerves. This intervention has good prognosis and low morbidity and mortality in well experiences surgical teams of thyroid surgery.

[Complications in thyroid surgery: symptomatic post-operative hypoparathyroidism incidence, surgical technique, and treatment]. / Complicanze in chirurgia tiroidea: ipoparatiroidismo sintomatico post-operatorio. Incidenza, note di tecnica chirurgica, prevenzione e trattamento.

INTRODUCTION: Total thyroidectomy has a definite role in the management of malignant and benign thyroid disorders, with minimal complications and rare postoperative mortality. Even though thyroid surgery is quite safe, mechanical damage, devascularization or inadvertent removal of the parathyroid glands are possible. The aim of this study is to report report the personal surgical experience and to define some of the pathologic and clinical characteristics of unintentional parathyroidectomy and post-thyroidectomy hypocalcemia. MATERIALS AND METHODS: A retrospective-observational study was carried on 313 thyroidectomies from January 2000 to January 2004 (60 males and 253 females), mean age 41 years (range 17-86 yrs). The positions of at least 3 parathyroid glands are defined, and are left within their fat envelope. Parathyroid glands and their vascular supply are preserved by individual ligation of the branches of the inferior thyroid artery on the surface of thyroid lobe. RESULTS: Over 313 thyroidectomy, in 3 cases (0.95%) the AA. accidentally removed parathyroid glands (1 superior and 2 inferior), transplanted in sternocleidomastoideus pouch. The overall incidence of temporary hypocalcemia was 5.4% and no cases of permanent hypocalcemia were registred, regressed after medical therapy. DISCUSSION: Prevention of complications in thyroid surgery is based on knowledge of embryology and anatomy of cervical district, to visualize and respect the glands and their vascular pedicle: the patients must be appropriately and preoperatively counselled regarding potential complications and they must be well aware of the surgical risk they are undertaken. It is possible by the identifications of risk factors. CONCLUSIONS: Postoperative hypocalcemia is the most immediate surgical complication of total thyroidectomy; it is a multifactorial phenomenon, where surgical technique has a greater phisiopatologic impact. However, hypoparatyroidism does not appeared to be the main reason for hypocalcemia after thyroidectomy, and other causes (surgical stress, "hungry bone syndrome", release of calcitonin during surgical manipulation) may be important contributory factors. In conclusion, as we exposed, extent of resection, surgical technique and thyroid pathologic condition had a greater impact on the rates of postoperative hypoparathyroidism. By developing understanding of the anatomy and the ways to prevent each complication, the surgeon can minimize each patient's risk and can handle complications expediently and avoid worse consequence.

[Infrequent early complication of mechanical digestive anastomosis: bleeding. Personal experience]. / Una rara complicanza precoce delle anastomosi digestive meccaniche: l'emorragia. Esperienza personale.

INTRODUCTION: Bleeding from mechanical digestive anastomosis is an uncommon complication (0.9-3.2%) often self-limiting but potentially lethal if not evidenced intraoperatively or in the immediate postoperative. MATERIAL AND METHODS: The Authors retrospectively report incidence of anastomotic bleeding after stapled anastomosis (11/163 = 6.7%) and analyse probable causes. In 6 of 11 patients (54%) intraoperative bleeding was stopped after manual reinforce of anastomosis (3/6) or stopped spontaneously (3/6). In 5 patients (45%), 1 with gastro-jejunal anastomosis, 2 with ileo-colonic anastomosis and 2 with colo-rectal anastomosis, they used endoscopy and endoscopic treatment in emergency. RESULTS: All 5 patients were treated with endoscopic clerotherapy (NaCl 0.9% plus epinephrine 1:10000): in 4 (80%) the Authors obtained hemostasis after the first treatment but in one of 2 cases ol ileo-colonic anastomosis (20%) the bleeding relapsed and the patient was re-operated. In 1 patient with the self-limiting lower anastomotic bleeding was associated to a Dieulafoy's gastric ulcer, perendoscopic treated successfully. In summary 2 patients were resubmitted to laparotomy, without evidence of source of bleeding. CONCLUSIONS: In accord with literature, bleeding from mechanical digestive anastomosis is a rare complication, often self-limiting (50-76%), that may be evidenced and treated early in intraoperative phase. Endoscopic examination may have diagnostic (source and type) and therapeutic valence, is effective, with low intrinsic risk and can reach endoscopic hemostasis without relaparotomy, except in case of rebleeding.

[Biliary stent placement for postoperative benign bile duct stenosis: personal experience]. / Il posizionamento di protesi biliari per stenosi biliari benigne post-operatorie. Nostra esperienza.

OBJECTIVE: To describe the management and outcome after endoscopic treatment of 23 patients with post-operative benign bile duct stricture (BBDS) managed in Authors' Department from 1991 to 2000. BACKGROUND DATA: The management of the postoperative bile duct strictures remains a challenge for even the most skilled biliary tract surgeon and endoscopist. The 1990s saw a dramatic increase in the incidence of bile duct strictures from the introduction and widespread use of laparoscopic cholecystectomy. The management of these injuries, short-term outcome and follow-up have been reported. METHODS: Data were collected retrospectively on 23 patients treated in the Service of Diagnostic and Operative Endoscopy of the Operative Unit of General and Thoracic Surgery (Policlinico Paolo Giaccone, Palermo, Italy) with BBDS between 1991 and 2000. All patients underwent ERCP (endoscopic retrograde cholangiopancreatography). Follow-up and pharmacological therapy post-ERCP were conducted by scheduled medical audit. RESULTS: Of the 23 initial patients, 20 undergoing endoscopic stenting (3 with complete transaction were invited to surgery), 16 had completed treatment with symptoms resolution (mean follow-up of 70 months). One patient died of reason unrelated to biliary tract disease before the completion of treatment. Seven had not completed treatment. Of 16 patient who had completed treatment, 13 were considered to have a successful outcome without the need of follow-up invasive, diagnostic or therapeutic interventional procedures. Overall, a successful outcome, was obtained in 65% of patients, including those requiring a secondary procedure for recurrent strictures. CONCLUSIONS: Postoperative bile duct strictures remain a considerable surgical challenge. Management with endoscopic cholangiography to delineate the postoperative anatomy and to place biliary stents, to solve the symptoms, is associated with a successful outcome in up of 65% of patients, in well experienced team. Endoscopic treatment should be the initial management of choice for postoperative bile duct stenosis, as a real alternative to surgical reconstruction: because his failure will not compromised the following surgical treatment prior endoscopic treatment does not preclude surgery), whereas endoscopic treatment is impossible one a Roux-en-Y loop has been constructed

[Mesenteric cyst lymphangioma; a case report and literature review]. / Linfangioma cistico mesenterico. Descrizione di un caso e revisione della letteratura.

OBJECTIVE: The Authors report their experience in diagnosis and treatment of one case of mesenteric cystic lymphangioma; recent international literature review. EXPERIMENTAL DESIGN: Complete clinical report. Diagnostic, clinical and prognostic indication, evaluation of effectiveness of radical surgical treatment and follow-up. SETTING: Operative Unit of General and Thoracic Surgery. University "Paolo Giaccone" of Palermo. INTERVENTION: Radical surgical treatment, according to international guide-lines. RESULTS: Complete recovery with "restitutio ad integrum". No relapse were recorded at short follow up. CONCLUSIONS: Even when asymptomatic and discovered incidentally, LCM must be treated surgically because of the potential to grow, invade vital structures, and develop life-threatening complications. The best and only radical treatment is the total removal of the lesions with microscopically clear borders, when it is available.

[Bronchial carcinoid: a review of the recent literature]. / Il carcinoide bronchiale: revisione della letteratura recente.

OBJECTIVE: To evaluate methods of diagnosis and treatment, and the long term survival of patients treated for bronchial carcinoid tumor by the review of recent literature. METHODS: The Authors conducted a retrospective study on internet-based-evidence of patients treated for bronchial carcinoid tumor since 1993 to 2004. Symptoms, diagnosis, operative approach and survival were assessed. CONCLUSIONS: On the basis of the review of the international literature, the Authors affirm that the 5 and 10-year probability of survival are closely linked to the histological type of carcinoid, to the presence of nodal and distant metastasis. Owing to the potential malignancy of these tumours, preference should be given to radical exeresis.

[Videolaparoscopic cholecystectomy: personal experience]. / Colecistectomia videolaparoscopica. Esperienza personale.

AIM: Laparoscopic cholecystecomy (LC) is now the gold standard for the treatment of gallstones. In this report were analyzed 153 LC performed by a single surgical team and, according to results, elaborated any technical recommendation. MATERIALS AND METHODS: 153 LC has been performed in Section of General and Thoracic Surgery of University of Palermo, Sicily, by a single surgical team, since 2000. Indications for LC were all forms of calculous cholecystitis (biliary colic in 73.2%, acute cholecystitis in 4.5%, gallbladder polyps in 5.8%) or colecystocoledochal lithiasis (9.8%). The mean age of patients was 49.46 years (range 18-78) and 62.7% were female. The patients were studied in our Section with hematochemical routine, plane chest roentgram, ECG, abdominal ultrasound (the day before the operation) and ASA classification (ASA I: 9.8%, ASA II: 67.3%, ASA III: 22.9%). RESULTS: All cases (153) were uneventful in terms of either serious intraoperative complications or necessity in relaparoscopy. In operatory room we adopted the French position, with mean operatory time of 65.03 minutes (range 30-180 minutes) and we also used the French technique of exposure of the cystic pedicle. The grade of difficulty of LC was analysed according 4 variables (approach to peritoneum, approach to gallbladder, pedicle dissection, cholecystectomy). There were 10 cases (6.5%) of convertions in total. Subhepatic space drainage was performed in 60.1% of cases. No postoperative biloma or subhepatic infiltration were observed. No port site infections were diagnosed, no port site hernias observed and no mortality observed. The mean postoperative bedstay was 2.21 days. CONCLUSIONS: LC is the treatment of choice for symptomatic gallstone disease. When performed by experienced surgeons, it is safe and effective.

[Surgical treatment of liver hydatidosis: our experience with diagnostic and therapeutic consideration]. / Il trattamento chirurgico dell'idatidosi epatica: nostra esperienza e considerazioni diagnostico-terapeutiche.

OBJECTIVE: The Authors report on their experience in diagnosis and treatment of liver hydatidosis (LH). MATERIALS AND METHODS: From January 2000 to December 2003, we observed 24 patients (10 male = 42% and 14 female = 58%, male/female ratio 1:1.4, range of age 23 - 80 years, mean age 45.25 years). The most frequent initial symptom was hepigastric and hypocondriac pain (82.6%), meanwhile acute abdominal pain was only in 26.1%. In one half of cases performed radical surgery (total pericistectomy), in 35% of cases the AA subtotal pericistectomy and only in 17% the AA partial pericistectomy. Only one left hepatectomy during total pericistectomy we performed. Major complications were registered, except a post-operative bleeding treated with 3 blood transfusion. The mean time of bedridden was 68 days (range 4 - 35, mode 7 days, median 7 days). All patients are actually in clinical, instrumental and serological follow-up as outpatients (3 months - 2 years): we not encountered any relapse. CONCLUSIONS: The surgical treatment of liver hydatidosis must to be radical (as in total pericistectomy), free from severe and disabling complications and without risks and relapses. The choice of type of surgery (radical or conservative) must came from attempt examination of anatomo-clinical tools and experience and agreement of surgical team.

[Treatment of gastrointestinal stromal tumor (GIST)--review of the literature and a case report]. / Il trattamento dei tumori stromali gastrici (GIST). Revisione della letteratura e descrizione di caso clinico.

BACKGROUND: Gastrointestinal stromal tumors (GIST) are rare mesenchimal tumors that are characterized by constitutive overexpression of the tyrosin-kinase receptor KIT (CD117). The authors analyse the basis of the treatment of gastric GIS, starting form the study of a recent observed case. EXPERIMENTAL DESIGN: Report of one case treated with endoscopic resection. Evaluation of treatment and 2-years follow-up. RESULTS: The treatment of gastric GIST must be modulated on prognostic, genetic and molecular factors. These factors are the basis of the formation and growth of GIST. CONCLUSIONS: Complete surgical extirpation without rupture remains the only curative treatment of localized favourable prognosis. Endoscopic treatment, as in our case, reflect the modulation of therapy on prognostic factors. Selective targeted therapy of metastatic disease yields encouraging clinical responses.

Acute pancreatitis during liver hydatidosis: treatment with ERCP and endoscopic sphincterotomy.

INTRODUCTION: The Authors report on a case of a young woman who developed acute pancreatitis when affected by liver hydatidosis, successfully treated with endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy. METHODS: An endoscopic sphincterotomy was performed, with extraction of multiple hydatid membranes. OBSERVATIONS: Laboratory values returned to normal within 36 hours of the sphincterotomy. The patient was dismissed with oral therapy (Albendazole 400 mg bis in die for 4 months) and antibodies to Echinococcus were not detectable 1 month later. One year later, at ultrasound and CT the hydatid cyst was regressed and patient was still without symptoms. CONCLUSIONS: Hydatid membranes in the biliary tract should be considered as a potential cause of pancreatitis in patients with hydatidosis, even if it is a rare complication, caused by the obstruction of the distal part of common bile duct by fragments of hydatid membranes, scolices or daughter cysts. ERCP may be beneficial, but surgery remains the treatment of choice for treatment of liver hydatid cysts.

[Endoscopic palliation of obstructive jaundice caused by inoperable pancreatic cancer: personal experience]. / La palliazione endoscopica dell'ittero ostruttivo da carcinoma inoperabile del pancreas. Nostra esperienza.

AIM OF THE STUDY: Few patients with pancreatic cancer are eligible for resection. In the remainder, estimation of prognosis is important to optimise various aspects of care, including palliation of biliary obstruction and trial of chemotherapy. The aim is to refer our personal experience about the palliation with endoscopic stenting in patients with unresectable pancreatic cancer. METHODS: The Authors reviewed retrospectively 132 patients affected by unresectable pancreatic cancer who underwent palliative interventions with endoscopic stenting from 2000 to 2004. RESULTS: Jaundice dramatically decreased in 86% of patients within 36 hours, in 12% within 48 hours and in 2% after two days. As complication were registered 3% of bleeding after endoscopic sphincterotomy, 2% mild acute post-ERCP pancreatitis and in 7% of patients transitory hyperamylasemia. The most frequent late complication was relapse of jaundice or cholangitis for stent clogging (51%) in a variable range fom 72.3 to 120.7 days, treated with stent substitution. No mortality ERCP-related was registered. CONCLUSION: Resection offers the only potentially curative approach to pancreatic cancer. The majority of patients are either too old, too ill with coexistent disease, or have a tumour that is undoubtedly inappropriate to resect. Thus for the vast majority an endoprosthesis to relieve the jaundice, is the preferred management, after a multidisciplinary approach.

[Substernal goitre. Personal experience]. / Il gozzo cervico-mediastinico. Esperienza personale.

INTRODUCTION: Aim of the study is to discuss the diagnostic and therapeutic problems of substernal goiter (SG). MATERIALS AND METHODS: The Authors retrospectively analyzed 12 patients (3.1%) with substernal goiters among 379 patients undergoing surgical treatment for thyroid diseases from January 2000 to 2005, and evaluated the clinical data, preoperative diagnostic findings, surgical treatments, histopathological results, and postoperative complications. RESULTS: The most common symptoms were a cervical mass (100%) and dyspnea (16%), but 50% of the patients were asymptomatic. Chest radiography provided the first evidence of a substernal goiter in 100% of the patients. The AA performed total thyroidectomy and operated through a cervical incision in all the patients. There was operative mortality (1 case: = 8%), 2 (16%) patients suffered temporary hypoparathyroidism; no patients suffered transient vocal cord paralysis. Malignancy was diagnosed by histopathological examination in 2 patients (16%). CONCLUSIONS: The presence of a substernal goiter is considerd as a sole indication for surgery. Surgical treatment of SG requires a diagnosis that exactly defines the extent of the lesion. A correct choice of surgical access and scrupulous operating technique are likewise of paramount importance to reduce the risk of severe compressive complications. Most retrosternal goiters can be resected through an entirely cervical approach with a low complication rate. On rare occasions a median sternotomy or a sternal split will be required to permit a safe and complete thyroidectomy.

An uncommon complication of liver biopsy: obstructive jaundice from blood clots.

INTRODUCTION: The AA. report on a case of one young woman who developed obstructive jaundice induced by hemobilia after percutaneous liver biopsy, successfully treated with endoscopic retrograde cholangiopancreatography (ERCP) METHODS: An endoscopic sphincterotomy was performed with extraction of the clots OBSERVATIONS: Four weeks after ERCP the patient was healthy and asymptomatic, valuated as outpatient CONCLUSIONS: The role of ERCP in managing biliary sequelae of hemobilia is well established: biliary decompression is required if and intrabiliary lot causes obstructive jaundice and/or biliary colic. ERCP is feasible and leads to relief of symptoms in most cases, without the need of surgery.
