The use of the venous stripper for graft removal in arterial reoperations.
A simple technique for removal of synthetic grafts using a standard venous stripper inside the graft is described. The method permits the simultaneous placement of a drainage tube in the canal after graft removal in cases where the graft is infected.

Metachronous leiomyosarcoma in colostomy after abdominoperineal resection for rectal carcinoma.
Leiomyosarcoma of the colon is a rare neoplasm. It is widely known that primary malignant lesions may present either simultaneously (synchronous tumor) or at different times (metachronous tumor). The incidence of metachronous colonic mucosal carcinoma is generally considered to range from 3 to 5%. Metachronous leiomyosarcoma in colostomy 4 years after abdominoperineal resection for rectal carcinoma is unusual and we have found no reports on this in the literature. The clinical symptoms, diagnostic features, and mode of treatment are discussed.

Leiomyoma of the anal canal: report of two cases.
Leiomyoma of the rectum and anal canal is an unusual clinical entity. Generally, it does not produce any clinical signs and in most cases it is discovered incidentally in the course of routine rectal examination. The clinical presentation, diagnosis, and surgical treatment are described in two presented cases of anal canal leiomyoma.

Bile composition and bile acid pool size. Comparison after truncal, selective, and highly selective vagotomy.
We studied biliary lipid composition and bile acid pool size in 29 patients surgically treated for duodenal ulcer. Fourteen were examined both before and after surgery, the rest postsurgically only. They were divided into three groups according to type of vagotomy. With duodenal fluid obtained via nasogastric tube, we determined bile acid pool size, bile concentrations, and lithogenic index. We found no significant differences in bile composition and bile acid pool size among the three types of vagotomy, postsurgically. However, patients studied before surgery, compared with the entire post-vagotomy group, had a significant increase in relative cholesterol content and lithogenic index, most pronounced in the truncal vagotomy group. Bile acid pool size was also increased postsurgically. Vagotomy may predispose to gallstone development by increasing the bile's relative cholesterol concentration and thus the lithogenic index. However, the slightly expanded bile acid pool size may improve cholesterol solubility in certain patients.

Desmoid tumor--review and follow-up of ten cases.
Ten cases of desmoid tumor, diagnosed, treated, and followed during the past 11 years, were reviewed and the patients reexamined. Two were up to 3 years, two up to 5 years, and four up to 11 years after excision. The remaining two patients were lost to follow-up. The 10 patients included one male and nine females; six females were of childbearing age and three were postmenopausal. In four females the desmoid tumor was located near various surgical scars. In the one recurrent desmoid it was most probably related to both repeated traumatization of the abdominal wall due to pregnancies and hyperestrogenism. All the surgical margins of resection were microscopically involved by the process. An open liver biopsy, performed simultaneously with the excision of the recurrent desmoid, showed benign nodular hyperplasia compatible with hyperestrogenism. Estrogen and progesterone receptors of this desmoid were negative. In the present series follow-up revealed, in contrast to general agreement, that in spite of incomplete excision, the recurrence rate was low. We suggest that the surgical approach to desmoid tumors could be less radical, except possibly for lesions in patients with multiple causative factors.

Torsion of a wandering spleen.
We present an unusual case of torsion of a wandering spleen in a 14 year old boy. Wandering spleen is an entity which has rarely been reported in infants and children. Although patients may be asymptomatic, some may present as an acute surgical emergency if trauma or torsion of the vascular pedicle occurs, as in our case. The treatment of this condition is splenectomy.

Bilateral primary malignant lymphoma of the breast.
A rare case of bilateral primary malignant lymphoma of breast in a 76 year old woman is presented. The lesion was examined by electron microscopy and immunochemistry. The diagnosis of primary malignant lymphoma remains a diagnosis by exclusion and requires extensive work-up to exclude widespread malignant process. The behaviour of this malignancy tends to be an aggressive one and the prognosis is generally poor.

Endoscopic treatment of suture line bleeding ulcer caused by nonabsorbable suture material in postvagotomy patients.
Two postvagotomy patients with upper gastrointestinal bleeding, which appeared several months after operation, are reported. Endoscopy showed the pyloroplasty suture line to be ulcerated and bleeding, with a few strands of silk protruding from edematous mucosa. The history of suture line ulceration and the contribution of endoscopy to its diagnosis and treatment are reviewed.

Primary gastrointestinal lymphoma: a review of 21 cases.
A retrospective study of 21 patients who had suffered from gastrointestinal lymphoma was carried out. Gastric involvement was more common than involvement of the small or large intestine and carried a better prognosis. Gastrointestinal lymphoma generally occurs most frequently during the fourth to seventh decades of life. In our study, however, five lymphomas occurred in patients under 20 years of age. Clinical symptoms were nonspecific, and abdominal mass was found in only 15% of the patients on clinical examination. All patients were explored, 17 underwent resection, and 4 laparotomy and biopsy. Five-year survival was much better for patients who had undergone resection. Survival was inversely proportionate to the extent of nodal spread. Multiple lesions on the same organ yielded a 5-year survival of 20%, while a single lesion offered a 55% chance of 5-year survival. Diffuse histiocytic lymphoma was the commonest type, followed by the poorly differentiated lymphocytic type. A longer survival rate was present in the lymphocytic type. However, the highest survival rate was in those patients in whom definite resections of the lesion were performed followed by radiation and chemotherapy, especially for gastric tumor.

Kidney fibroxanthoma (malignant fibrous xanthoma): a rare tumor and an unusual cause of retroperitoneal hemorrhage.
A case of kidney fibroxanthoma (malignant fibrous xanthoma, malignant variant of xanthogranuloma), a rare malignant neoplasm of kidney, is described. In addition to the typical histologic features of retroperitoneal xanthogranuloma, this tumor showed obvious pleomorphism and mitotic activity of the histiocytes. We present this case in view of the rarity of this neoplasm and the unusual presentation as massive retroperitoneal hemorrhage.

Anal erotic instrumentation. A surgical problem.
Anal sexual eroticism is a fact of modern life and a part of the male homosexual relationship. A delineation of surgical problems associated with anal erotic instrumentation with enema is presented. The cases of three patients with rectal perforation are described.

Massive intraabdominal bleeding due to a retroperitoneal leiomyosarcoma.
Retroperitoneal leiomyosarcomas are rare and show a tendency toward large size, cystic degeneration, bleeding, and extensions by infiltration to the adjacent structures. An unusual case of a retroperitoneal cystic leiomyosarcoma with massive intraabdominal bleeding is presented.

Inflammatory fibroid polyp of sigmoid colon.
A case of inflammatory fibroid polyp of the sigmoid colon is presented. This is the eight case of this type of polyp in the colon and, to the best of our knowledge, the first one involving the sigmoid and producing intussusception. Symptomatology of the inflamed fibroid polyp in this part of the gut closely simulates gastrointestinal malignancy. The treatment is surgical excision of the polyp, or colonoscopic resection when it is possible. Intraoperative colonoscopy helps the surgeon to localize the lesion and to role out the existence of other lesions.
