[Bilateral hydronephrosis secondary to ileocolic Crohn's disease]. / Hidronefrosis bilateral secundaria a enfermedad de Crohn ileocólica.

Unilateral hydronephrosis can complicate a far from negligible number of patients with Crohn's disease. Bilateral hydronephrosis associated with Crohn's disease is a much more unusual entity. In the other hand, the treatment for this condition is still controversial. We present the case of a 44 year old female with several bowel obstruction episodes caused by ileocolic Crohn's disease. During the last episode she was also diagnosed of bilateral hydroureter and hydronephrosis. After the resolution of the bowel obstruction and the placement of a double J catheter in both ureters, the patient was operated. Ileocolic resection and bilateral ureterolysis with omental wrapping were performed. Although urinary and wound infection complicated the postoperative course, and a enterocutaneous fistula had to be medically treated one year later, the patient is now free of symptoms and her renal function is normal.

Hidronefrosis bilateral secundaria a enfermedad de Crohn ileocólica / Bilateral hydronephrosis secondary to ileocolic Crohn's disease

La hidronefrosis unilateral puede complicar a un número no despreciable de pacientes con enfermedad de Crohn. La hidronefrosis bilateral también puede asociarse a la enfermedad de Crohn, pero aparece con mucha menos frecuencia. Por otro lado, existe controversia sobre el tratamiento más adecuado de esta entidad. Presentamos el caso de una paciente de 44 años con cuadros de obstrucción intestinal de repetición por enfermedad de Crohn ileocólica, que en el último ingreso fue diagnosticada también de hidrouréter e hidronefrosis bilateral. Tras la resolución del episodio obstructivo y previa colocación de catéteres doble J en ambos uréteres, la paciente fue sometida a resección ileocólica y ureterolisis bilateral con epiploplastia. Aunque aparecieron complicaciones menores inmediatas como infección urinaria y de herida y un año más tarde se trató médicamente una fístula enterocutánea, la paciente está actualmente asintomática y su función renal es normal (AU)

[Effects of total gastrectomy on the nutritional status]. / Efectos de la gastrectomía total sobre el estado nutricional.

In this study, we have analyzed a series of 88 patients who underwent total gastrectomy followed by two different reconstructive procedures, Roux-en-Y jejunal interposition (57%) and interposition of a jejunal limb between the oesophagus and the duodenum (38%) (Henley procedure). We examined diet, intestinal transit, symptoms of dumping syndrome and body weight curves. Patients with Roux-en-Y reconstruction presented post-prandial sweating more often (48%) than patients with the Henley procedure (21%). Forty percent patients with Roux-en-Y reconstruction suffered post-prandial nausea whereas this finding was not associated with patients after the Henley procedure. The reconstructive method has to be chosen considering the age and general condition of the patient, stage of the neoplasia and its curability. We currently favor Roux-en-Y esophagojejunostomy. However, in selected patients the Henley procedure may prove useful in order to prevent reflux and dumping symptoms.

[The treatment of acute liver failure due to fulminating hepatitis by total or partial orthotopic liver transplantation. The clinical results]. / Il trattamento dell'insufficienza epatica acuta per epatite fulminante mediante trapianto epatico ortotopico totale o parziale. Risultati clinici.

Indications for liver transplant in acute fulminating hepatitis (AFH) are predominantly affected by the high mortality of this spontaneous evolution (80-100%). At present patients with AFH have priority for transplant since they form part of the 0 emergency group according to the National Transplant Organisation. During the period between 1986 and the end of February 1992, a total of 254 liver transplants were performed in 202 patients (52 retransplants). In 26 patients (12.8%) (16 females and 10 males) the indication was fulminating acute hepatitis. Etiology was unknown in 20 patients, secondary to hepatitis B in 4 and to hepatitis A in 1, and was caused by isonazide ingestion in 1 case. The age limits were 3-60 years (X = 31.5 years). An isogroup graft was performed in 16 patients (61.5%), compatible in 3 (11.6%) and incompatible in 7 (26.9%). Due to anthropometric differences, a partial graft was used in 7 patients (26.9%); in 2 of the latter the graft was taken from the same donor ("split-liver"). Placement was always orthotopic with resection of the retrohepatic vena cava in 25 patients and its preservation in 1 (left lobe of split-liver). Peroperative (30 days) mortality was 23% (6/26); 2 due to cerebral death, 2 due to sepsis, 1 due to multisystemic insufficiency (MSI) and 1 due to acute pancreatitis. Four patients (15.3%) died some time after transplant; 1 after 5 months due to broncho-pulmonary complications, 1 after 7 months due to subacute hepatitis, 1 after 3 months due to respiratory failure and the last after 5 months due to anoxic encephalopathy and lung infection. Ten patients (39.4%) were re-transplanted; 4 following chronic rejection, 4 due to primary graft no function, 1 due to arterial thrombosis and 1 due to recurrent hepatitis (with cirrhosis). Two of the latter patients died intraoperatively due to coagulopathy and hemorrhage, and 3 following surgery (1 due to sepsis, 1 due to respiratory complications and 1 due to respiratory insufficiency). Two patients underwent a second re-transplant (1 due to chronic rejection and 1 due to recurrent hepatitis) and of these 1 died peroperatively due to sepsis and MSF. Overall mortality was therefore 61.5% (16/26) and the actuarial survival rate of 17 patients (10 living + 7 postoperative deaths) was 68% at 12 months and 52.9% at 36 months. Even if peroperative mortality is relatively high, liver transplant is currently the elective treatment for fulminating acute hepatitis.

Surgical treatment of congenital dilatation of the biliary system.

Six out of 1,612 patients operated on for biliary diseases between January 1974 and January 1985, had Caroli's disease. A summary of the clinical records is included. The treatment performed was: external drainage in a patient with sepsis, who did not improve and died; left hepatic lobectomy and biliary-jejunal diversion in two patients; right extended lobectomy in one patient; distal spleno-renal shunt in a patient with severe biliary cirrhosis and recurrent hemorrhage from esophageal varices. The last patient suffered from a combination of a choledochal cyst and dilatation of the left intrahepatic branches, and underwent complete resection of the choledochal cyst, and biliary jejunal anastomosis on a porta-hepatis using a Roux-en-Y jejunal loop. Currently, five patients are recovering and are free of symptoms. The authors discuss the indications for liver resection and resection of a choledochal cyst.

Esophageal resection by cervico-abdominal approach without thoracotomy.

The authors report their experience with transhiatal esophageal resection accumulated during the period between January 1978 and March 1990. Indications for the procedure included cancer of the gastric cardia (26.3%), cancer of the hypopharynx (3.8%), cancer of the esophagus (59.2%), and benign esophageal disease (9.8%). Esophageal substitution was performed using a tubulized stomach (63.6%), ileo-ceco-coloplasty (28.5%), left colon (7.6%), and jejunum (0.3%). The majority of patients with neoplastic disease were found to be in an advanced stage (67.3% of esophageal cancer patients and 69.7% of cancer of the cardia patients with stage III disease). The mean intra-operative volume of blood transfused varied between 533 and 1,220 ml. Sixteen patients required hospitalization in the intensive care unit. The mean length of post-operative hospitalization varied between 16.8 and 20.6 days. Operative complications included hemorrhage (0.3%) and tracheal injury (0.6%). Operative (30 day) mortality was 5.8%. Causes of death included respiratory insufficiency (35.2%), pulmonary sepsis (23.5%), abdominal sepsis (17.8%), and others (undefined, 23.5%). The 5 year survival was 48.5% for cancer of the gastric cardia, 57.1% for cancer of the hypopharynx and 11.8% for esophageal cancer.

[The surgical treatment of esophageal leiomyomas: a report of 9 cases and a review of the literature]. / Tratamiento quirúrgico de los leiomiomas esofágicos: aportación de nueve casos y revisión de la literatura.

We report a series of 9 leiomyomas of the esophagus treated surgically. We review the literature, emphasizing diagnostic and therapeutic aspects, calling special attention to the good results obtained by submucosal enucleation of the tumor.

Hepatic myelolipoma: new case and review of the literature.

We present a case of hepatic myelolipoma that was treated by performing a right hepatic lobectomy. These tumors are very uncommon and present great problems for the pre-operative diagnostic evaluation. Currently, the diagnosis is essentially histopathological with a definitive diagnosis being made by immunocytochemical staining. We have found no reports on this type of tumor in the Spanish literature; a review of the published cases confirms our observations and conclusions regarding hepatic myelolipoma.

[Liver transplantation and portal thrombosis]. / Trapianto epatico e trombosi portale.

One hundred and thirty-eight transplants were performed between April 1986 and June 1990 in 116 patients of whom 9 (7.75%) were affected by liver cirrhosis complicated by portal vein thrombosis. Occlusion of the vascular lumen was total in 3 cases, semitotal in 1 case and the percentage of obstruction ranged between 25% and 75% in the remaining patients. Venous dissection and thrombectomy were performed in 6 cases and simple thrombectomy in 3 cases in order to obtain a satisfactory blood flow. Anastomosis was effected using the spleno-mesenteric confluence in 2 cases and the portal vein itself in other patients. Recurrent thrombosis occurred in the first 4 patients in the series, but it was only fatal in 2 cases. The paper analyses the data obtained from the study and in conclusion confirms the use of transplant in cirrhotic patients with portal vein thrombosis.

[Orthotopic liver transplantation: results at the "12 de Octubre" Hospital]. / Trasplante hepático ortotópico: resultados del Hospital "12 de Octubre".

The authors report their experience on 132 liver transplants performed on 111 patients. Eighteen have a re-transplantation and in 3 of them a second retransplantation (total re-transplanted patients 21 = 15.9%). Hepatic cirrhosis was the most common indication (57.65%) for transplantation (34.37% of alcoholic etiology). The authors report briefly their operative techniques and the results of their experience. The per-operative mortality (30 days) was 16.21% (18/111). The most important complications were: 9 hepatic arterial thromboses (6.8%), 4 arterial strictures (3.03%), 1 portal stricture (0.75%), 4 portal vein thromboses (3.03%), 5 biliary fistulae (3.78%) (3 following biliary duct-to-duct anastomosis and 2 following hepatic-jejunoanastomosis) and 2 strictures of the choledocus (1.51%). The actuarial survival rate (48 months) is 80%.

[Intraoperative cholangiography: its value in simple cholelithiasis]. / Colangiografía intraoperatoria: valor en la colelitiasis simple.

The present study evaluates the benefits of systematic intraoperative cholangiography (CIO) in 144 patients without preoperative suspicion of choledocholithiasis. Eleven (7.6%) of the intraoperative cholangiographies were considered abnormal by the surgeon and the presence of choledocholithiasis (3/11, 27%) was confirmed in only three cases. Pathology of the main bile duct that had been unsuspected preoperatively was found in only 2% (3/144). We conclude that routine intraoperative cholangiography of patients without preoperative suspicion of choledocholithiasis increases the cost of surgery, prolongs operative time, exposes the patient to radiation and sometimes yields false positives (5%) that lead to unnecessary exploration of the choledochus, which is accompanied by a potential increase in morbidity and a real prolongation of the postoperative hospital stay.
