RESUMEN

BACKGROUND: Hepatic hydrothorax is a less common complication of cirrhosis with an estimated prevalence of 10- 15%. In the vast majority of cases, ascites are also present but significant pleural effusion may develop in patients without ascites. Hepatic hydrothorax is associated with cirrhosis whatever its etiology. The prognosis of hepatic hydrothorax remains unclear and is closely related to available therapeutic options. The aim of our study is to determine the prevalence of hydrothorax in cirrhotic patients, detail its clinical and therapeutic characteristics, and study the evolutive profile of cirrhotic patients with hydrothorax by comparing it to those without hydrothorax. We also search predictive factors of development of this complication in cirrhotic patients. METHODS: We conduct a retrospective and case-control study including 63 cirrhotic patients with hepatic hydrothorax hospitalized in gastroenterology department of Charles Nicolle hospital of Tunis, during a period of fiveteen years, from January 2000 to January 2015. RESULTS: The prevalence of hydrothorax was 14.5%. The mean age was 62 ± 14 years (range, 22- 86 years). The sex ratio H/F was 1.52. Hepatic hydrothorax was symptomatic in 35 patients. It was right-sided in 60%, left-sided in 24% and bilateral in 16% of cases. Hydrothorax was on average size abundance in 54% of cases. It was transsudatif in 52.5% of cases. Hepatitis C was the most frequent cause of cirrhosis (54%). Our results show that hepatic hydrothorax was present with important ascites in 35 patients. Hydrothorax was significantly related to Child-Pugh C severity of cirrhosis (p=0.0001). Hydrothorax occurence was significantly associated with a low level of albumin (p=0.001), an important hyponatremia (p=0.001) and a low prothrombin rate (p=0.02). A therapeutic thoracentesis was performed in 57% of cases. Diuretics based on spironolactone and furosemide were indicated in 30 patients. Evolution was favorable in 19 patients. Refractory hepatic hydrothorax was present in 31 patients. Death, in the days which follow the hospitalisation, was in 13 patients. The 5-years survival rate was 60%. The mean survival time of patients with hepatic hydrothorax was 8.41 years against 10.75 years at patients without hepatic hydrothorax. CONCLUSION: Hepatic hydrothorax is a common complication in our study. The improvement of the prognosis of our patients would require a better therapeutic management and especially the possibility of orthotopic liver transplantation which is the optimal therapeutic option for patients with hepatic hydrothorax.

RESUMEN

BACKGROUND: Obesity raises such a healthcare matter throughout the world. Its management is not only complex but also most often multidisciplinary. The medico-dietary treatment is of inconstant efficiency and the surgical treatment, though more efficient, presents a considerable morbidity-death rate. The endoscopic treatment through intra-gastric balloon avails a seducing alternative namely accounting for surgery preparation. AIM: To assess the efficiency of the endoscopic treatment through gastric balloon, both in the short and long term, and this is accounting for weight loss as well as tolerance. METHODS: We have carried out a retrospective study including the patients suffering from severe to morbid obesity and who had a gastric balloon implemented in our Endoscopy Unit between November 2005 and December 2007. RESULTS: Twenty one patients were included. The average age was 32,19 ± 12,65 years with extremes of 16 and 52 years. Fifteen patients suffered from morbid obesity. The patients' average weight was 134, 52 ± 26,46 kg (extremes 88 and 194 kg). Some co-morbidity was found out with 15 patients. Te balloon implementation (Héliosphère®) was carried out with no incidents in all patients. Six months after the balloon implementation, the average weight loss was 17,5% and the average loss of over weigh was 37%. In biological level, we noted a normalisation of fasting glycaemia in 28,6 % of cases, of the cholesterolemia in 100 %, of the triglyceridemia in 33,33%, of the uraemia in 42,8% and hepatic tests in 50 % of the cases. The metabolic syndrome disappeared in 28,57 % of cases. The assessment after a 5-year-period was marked by the need to surgical treatment in 4 patients and this is due to the loss of efficiency of endoscopic treatment. A bad tolerance of gastric balloon was observed in 34 % of the cases, dominated by sicknesses. Only one patient presented incoercible sicknesses with ionic troubles as well as deshydrating requiring the precocious extraction of the balloon after 48 hours of its implementation. CONCLUSION: The endoscopic treatment through intra gastric balloon is well tolerated but efficiently limited in time. It might be recommended in preparation for a surgical treatment or in case of contre- indication or surgery refusal.

RESUMEN

BACKGROUND: Hepatitis C virus (HCV) infection is one of the main causes of chronic liver disease worldwide. AIM: To describe epidemiological patterns of hepatitis C in Tunisia. METHODS: Literature review. RESULTS: In Tunisia, the prevalence of HCV infection is about 0, 7 % in the general population with an increased transmission in the north of the country. Genotype 1b is the most frequent (76 % - 88 %).

RESUMEN

Congenital megacaecum is a rare entity and difficult to diagnose. The pathogenesis of this malformation is not well known since there are very few cases reported in the literature. The purpose of this observation is to describe the functional signs that may suggest this rare diagnosis and the means to confirm it. We report the case of a 22-year-old young man, who complained of constipation associated with pelvic pain in the form of gravitational pull exacerbated by standing, sitting and going down the stairs. However, symptoms seemed to be relieved by supine positions. The radiological investigations concluded that the megacaecum dipped into the pelvis, but there was no evidence of mechanical or functional obstruction distally. The treatment consisted of a laparoscopic right colectomy. The postoperative course was uneventful. The megacaecum is rare and poorly understood. The abdominal pain is directly related to fecal stasis, which increases the pressure on cecal colonic segment and this in turn causes a pull on the mesentery. The entero-MRI is valuable in the diagnosis so as to eliminate other causes of chronic abdominal pain.
