Posthemipelvectomy hernia.

We report the case of a white male who underwent a classic hemipelvectomy due to a femur fibrosarcoma with inguinal metastases, which 33 years later, developed into a posthemipelvectomy hernia in the amputation stump that impaired the use of his Canadian prosthesis. The hernia was repaired with a polypropylene mesh in a subaponeurotic position. A seroma was drained in the postoperative and it was only 2 months after the operation that he could use his prosthesis with any difficulty. A year after the operation, the hernia had not recurred. Only seven similar cases have been published, and there are only four cases with details of their correction, two with a mesh as was our case, and the rest with a primary suture of the aponeurotic borders. A brief review of the bibliography is given on this subject.

[Pain and jaundice secondary to hemobilia resolved by ERCP and endoscopic sphincterectomy].

We report the case of a patient with hemobilia resulting from a liver biopsy where the performance of the endoscopic sphincterectomy solved the jaundice and the pain of the patient. ERCP has been used previously in the diagnosis of biliary and pancreatic tumors that manifested themselves as an hemobilia. The therapeutic utilization of endoscopic sphincterotomy had been described rarely in this type of bleedings. We recommend endoscopic retrograde cholangiopancreatography and sphincterotomy in the cases of hemobilia with severe abdominal pain resulting from the accumulation of clots inside the biliary tract.

[Morphologic changes in ileoanal reservoirs 2 years after their construction].

A study was made of the histologic changes in the mucosa of the ileoanal reservoirs of 10 patients who 2 years earlier had undergone ileoanal anastomosis with a J reservoir for ulcerative colitis (CU). In biopsies of the reservoirs were evaluated: 1) basic morphologic changes; 2) morphometric differences with respect to normal ileal mucosa; 3) the immunohistochemical pattern (IHQ) (IgA, IgG, IgM and CEA) of the reservoir mucosa as compared to normal ileum, active ulcerative colitis. Crohn's disease and celiaca; 4) the possible existence of atypias or dysplasias of the reservoir mucosa; and 5) the number of argentaffin cells per field. The basic morphologic alteration consisted of colonic metaplasia. Reservoir biopsies exhibited partial (8 cases) or subtotal atrophy (2 cases) of the mucosa. With respect to the normal ileum there was a decrease in villi height (p less than 0.05), an increase in crypt depth (p less than 0.05) and a higher index of mucosal regeneration, with a larger number of cells and mitoses per crypt (p less than 0.05). Fifty percent of the reservoirs presented a chronic inflammatory pattern with an acute component in 30% of them. The immunohistochemical pattern of the reservoirs not inflamed was similar to that of normal ileum (IgA much greater than IgM greater than IgG) and that of the inflamed reservoirs was similar to that of intestinal inflammatory disease (marked increase in the IgG. CEA (similar to what?) an alteration of local immune homeostasis could have of the genesis of pictures of "pouchitis". No alarming signs of atypia or dysplasia were found, nor changes in the population of argentaffin cells.

[Intestinal fistula in Crohn disease].

The treatment of patients with Crohn's disease (CD) presenting intestinal fistulas is debated. A retrospective analysis was made of the treatment of 26 patients with Crohn's disease who had a total of 37 fistulas: 28 internal and 9 external. In 19 patients the fistulas were single and in 7 multiple; in most patients the fistula originated on the terminal ileum. Crohn's disease was ileal in 10 patients, ileocolonic in 15 and exclusively colonic in 1, and the evolution of the disease from the onset of symptoms to the appearance of the fistula was a mean of 5.8 years. The diagnosis, except for two patients in whom it was an operative finding, was based on the clinical examination and radiology studies. All the patients, except for four with asymptomatic internal fistulas, underwent medical treatment as needed. Six patients required only medical treatment, and the rest, 16, received medical and surgical treatment. Surgical treatment consisted basically of resection of the intestinal segment affected by the fistula, with or without anastomosis. The operative mortality was 0% and the morbidity was 25%, the most frequent complication being infection of the surgical wound. All the patients with external fistulas required surgical treatment. In every case the fistula was single. The treatment of internal fistulas in conditioned by the symptoms the response to medical treatment and the presence or not of associated pathology. Asymptomatic patients or those who responded to medical treatment had single fistulas.

Correction of amino-acid imbalance in postoperative portosystemic shunts.

We report on 22 cirrhotic patients suffering from portal hypertension and bleeding esophageal varices. Sixteen of them underwent H mesocaval shunt with internal jugular vein graft and 6 spleno-renal shunts. Mortality was 13.2%. All the patients were treated postoperatively with parenteral and oral nutritional support with solutions containing no aromatic amino-acids, following Fischer's formula. We determined Fischer's index (formula; see text); normal value 2.67 +/- 0.22) on the day of operation (1.6 +/- 0.22), on the 8th postoperative day (2.32 +/- 0.49), and on the 15th postoperative day (1.85 +/- 0.37). Only 1 patient suffered from hepatic encephalopathy in the immediate postoperative period. Three months after operation Fischer's index was 1.20 +/- 0.11 and only 2 patients with an index below 1 suffered from chronic encephalopathy. We conclude that there is a correlation between Fischer's index and the presence of post-shunt hepatic encephalopathy. The proposed policy of parenteral nutrition improves the values of Fischer's index in the immediate postoperative period and we believe that nutritional support should be included routinely as an adjuvant therapy in portosystemic shunts in cirrhotic patients.

[Clinical and functional results after Laparoscopic fundoplication. Prospective evaluation].

OBJECTIVE: To prospectively assess the medium- and long-term clinical and functional results in consecutive patients undergoing laparoscopic procedures for gastroesophageal reflux. PATIENTS AND METHOD: The series included the interventions performed or assisted by the first author in 325 patients referred for surgical evaluation between December 1992 and June 2000. Forty patients were excluded from the study because they did not fulfil the inclusion criteria for laparoscopic surgery. A further 20 patients who underwent laparoscopic surgery were excluded because they required conversion to open surgery. Thus, 265 patients were included in the study. One hundred ninety-six total fundoplications (Nissen-Rossetti) and 69 partial fundoplications(42 posterior-Toupet and 27 anterior-Dor) were performed. The surgical technique employed was a slight modification of that described by Dallemagne et al with five-trocars. Preoperative evaluation was established by clinical features, endoscopy with biopsy, barium contrast radiography, esophageal manometry and esophageal pH monitoring. RESULTS: The mean follow-up was 47.1 3.3 months (range: 4-92 months). Heartburn, regurgitation, and dysphagia were relieved in 92.5%, 97.7%, and 88.1% of patients respectively. Complete relief of symptoms was achieved in all patients who presented preoperative respiratory symptoms as a complication of gastroesophageal reflux. Esophagitis healed in 98.2% of patients with preoperative esophagitis. Correction of lower esophageal sphincter pressure and lower esophageal sphincter length were statistically significant compared with preoperative status (p = 0.006 and p = 0.003, respectively). Pre- and postoperative differences in the percentage of patients with a pH < 4 in 24-hour ambulatory esophageal pH monitoring were also significant (p = 0.005), confirming correction of acid reflux. Morbidity appeared in 6.7% of patients and there was no mortality. Conversion to open procedures was required in 7.5%. The mean operative time was 115 6.3 minutes. CONCLUSIONS: These preliminary results suggest that when performed by experienced surgeons laparoscopic fundoplication provides an excellent alternative in selected patients with gastroesophageal reflux. Both medium- and long-term clinical and functional results, as well as morbidity, were satisfactory and were similar to those of open fundoplication.

Hemosuccus pancreaticus in a heterotopic jejunal pancreas.

Heterotopic pancreas is a congenital anomaly defined as pancreatic tissue occurring outside its normal anatomical location, lacking both anatomic and vascular connections. Ninety percent of heterotopic pancreas is found in the upper part of the gastrointestinal tract. Symptoms, when present, are normally non-specific and include abdominal pain, nausea, vomiting and bleeding. However, aberrant pancreas is not often recognized as patients are usually symptom-free. We report on a 29 year-old man with acute and severe gastrointestinal hemorrhage through the duct of an aberrant pancreas located in the upper jejunum, without clinical or histological evidence of pancreatic inflammation. We believe that our case is the first description of a pancreatic ductal hemorrhage in an aberrant pancreas.

Dermoid cyst of the pancreas: a rare cystic neoplasm.

Dermoid cysts of the pancreas, also called cystic teratomas, are a rare entity and are included in the group of neoplasms with a germ cell origin. Only twelve cases have been described in the world literature. The symptomatology is due to tumor compression of the neighboring tissues. Ultrasonography and computed tomography may be helpful, but there are no pathognomonic data for their preoperative recognition. The differential diagnosis should include all other cystic tumors of the pancreas. Complete surgical removal is mandatory. We describe the diagnostic and surgical procedures in a 74 year-old man with a pre-operatively unsuspected dermoid cyst. We review the previously published cases and emphasize the appropriate therapeutical management.
