[Our surgical experience in the resection of benign hepatic tumors. Apropos of 31 cases].

The authors report their experience about 31 patients (30 women and 1 man, mean age 45,7 years) opered for a benign hepatic tumor between 1984 and 1993. There were 12 focal nodular hyperplasia, 9 simple hepatic cysts, 8 hemangioma and 1 hepatic adenoma. All but one (a cyst) tumors were completely resected. The reasons of indications for surgery (which is contraversial) are then discussed, most of them being based on doubts concerning correct identification of the tumor (despite a modern assessment by imaging) or symptoms or risks of the tumor.

[Intraluminal polyp of the common bile duct corresponding to a metastasis of cancer of the kidney].

The authors report the second case to date of metastatic carcinoma of the common bile-duct from renal cell cancer presenting as an intraluminal polypoid mass. Obstructive jaundice developed in a 55-year old woman 14 years after nephrectomy for renal cell carcinoma. The diagnosis of polypoid tumor of the common bile-duct was established by sonography, endoscopic retrograde cholangiopancreatography and CT-scan. Palliative resection was performed. Postoperative histological examination revealed the resected tumor to be identical to the clear cell type of renal cell carcinoma. The postoperative course was marked by the development of distant metastases 6 months later. Diagnosis and therapeutic features of metastatic malignant biliary obstruction are discussed.

[Transanal excision of villous tumors. Value of the Endo-GIA 30 Multifire clamp].

The authors describe a new surgical procedure applied to the treatment of villous adenoma of the rectum. The mechanical device called Endo-GIA 30 Multifire (Merlin Médical, F69672 Bron), an automatic suture clamp regularly used in laparoscopic surgery, facilitates complete excision of villous adenomas if the tumour is located less than 10 cm from the anal margin.

Adenoma↗

[Acute Budd-Chiari syndrome following hepatectomy. Apropos of two cases].

The authors report about 2 cases of Budd-Chiari syndrome occurring during the immediate postoperative period of extensive hepatectomy, after exeresis of a large biliary cyst (20 cm in diameter) through 6/7 sectoriectomy and after exeresis of a large sarcomatous tumor preserving only sectors 2 and 3 of the liver using an "ex-vivo/in-situ" technique. These 2 cases lead to discuss the diagnosis, treatment and, most importantly, the prevention of acute suprahepatic obstruction after extensive right hepatectomy. Similar cases are reported in the literature after partial liver transplantation. Prevention basically consists in tethering the remaining liver to prevent rotation around the vena cava or the remaining suprahepatic vein. The emptied subphrenic fossa may be filled up using the omentum or the right flexure of the colon.

Acute Disease↗

[Splenic metastases. Apropos of 4 cases].

The authors report about 4 cases of splenic metastases in patients with the following neoplasms: urothelial carcinoma of the left kidney, adenocarcinoma of the uterine body, adenocarcinoma of the left flexure of the colon, adenocarcinoma of the sigmoid loop. On large autopsy series, metastases to the spleen are not rare (7% in average), and rank 10th among the 44 metastatic sites described in the literature. Cancers of the breast, lung, skin (melanoma), ovaries and stomach (cardia) make up more than 60% of the primary tumors. The diagnosis is most often accidental (surveillance of operated patients), rarely clinical (pain, splenomegaly), and it is based on medical imaging (ultrasound, CT). In the absence of hemostatic disorders, percutaneous needle biopsies are possible. Treatment, when at all possible, is surgical (splenectomy) and must comply with carcinological rules.

[Reoperations of rectal resection for recurrence after previous resection for rectosigmoid cancer].

From June 1986 to December 1992, 16 patients (12 men and 4 women, 63 years-old [36 to 79]) who underwent a prior sphincter-saving resection for colorectal adenocarcinoma were operated on for locoregional recurrence with a surgical resection. Eight patients had a second anterior resection (5 colorectal, 2 coloanal and 1 ileoanal anastomosis), one a resection without anastomosis, and 7 an abdomino-perineal resection. Nine patients received an intraoperative irradiation (10 to 25 Gy). Excisions of surrounding organs were often necessary. Post-operative complications occurred in most of the patients. Excluding 3 post-operative deaths, 9 patients died of disease in a median of 12.9 months after surgery (range: 3 to 32 months). Four patients are still living 5 to 14 months after the second resection. There is little in the surgical literature dealing with these difficult surgical problem of which results are always uncertain. An earlier diagnosis of the recurrence would result in a more satisfactory procedure, but is difficult because of the limited possibilities of detection after surgical treatment and often external irradiation.

[Clinical characteristics and evolution of permanent digestive ostomies. Results of a nation-wide retrospective survey].

Factors influencing the achievement and the evolution of permanent stomas were determined during a National Inquiry including 1,082 stomas (978 colostomies and 104 ileostomies). This study, although not exhaustive, was representative, giving its statistical value. The principal concepts are well known with regard to the indications of colostomies (cancer) and ileostomies (inflammatory bowel diseases), to age (older in patients with colostomies: 63.8 vs 41.7 years, P < 0.001) and to the unequal geographical distribution of ileostomies (most frequent in northern provinces: P = 0.02). Frequency of complications (25%) after definitive stoma have decreased since 1985 (P = 0.01) but reoperation was necessary in 50% of cases. Most patients were informed of their stoma before the operation, but 23% were not. Among the informed patients, one fourth considered themselves insufficiently acquainted with their stoma.

[An unusual secondary localization of bronchial adenocarcinoma].

The authors report a rare case of metastatic carcinoma of the large bowel, secondary to a primary bronchogenic adenocarcinoma. Abdominal pain developed in a 44-year old man 5 months after lobectomy for lung adenocarcinoma. The diagnosis of a large caecal extraluminal mass was established by means of sonography, scanner and laparoscopy. Palliative resection (brain metastases) was performed. Postoperative histological examination revealed the resected tumor to be identical to the lung adenocarcinoma. The patient eventually died 4 months after resection (complication of intracranial hypertension). Diagnosis and therapeutic features of metastatic extra-thoracic lung carcinoma are discussed.

[Mechanical resection of rectal tumors by transanal way under rectoscopic control. Results of a new surgical technique].

The authors report the results of a new surgical procedure used in the treatment of rectal tumours. The mechanic devices Endo-Gia* 30 Multifire (Merlin Médical, SA, F-69672 Bron) was used in 8 cases (7 patients) in order to treat carcinoid tumours (n = 2) and villous polyp either with intermediate or severe dysplasia (n = 5) or transformed in Dukes A adenocarcinoma (n = 1). In 7 cases the follow-up was uneventful. In 1 case temporary rectal bleeding occurred.

[Cytological study in case of gastric leiomyoblastoma. Review of the literature].

The authors describe the fine-needle aspiration cytologic features of leiomyoblastoma. Aspirated tumor cells occur singly, not in clusters. The tumor cells are globular in shape or sometimes have a spindle appearance. The nuclei are round, central or eccentric, with small nucleoli. The cells have well-defined cytoplasmic borders. The cytoplasm is abundant and, to some extent, granular, with sometimes a microvacuolar peripheral pattern. To date five cases of leiomyoblastoma with a cytological study have been published, two of them located to the stomach. A review of the literature is presented.

[Aimed fistulization in spontaneous ruptures of the thoracic esophagus after delayed diagnosis. Apropos of 4 cases].

Of four cases of spontaneous rupture of thoracic esophagus treated, three were the object of direct fistulization on a Kehr's drain because of the delay in diagnosis. This technique remains valid since it provides satisfactory drainage without excluding the focus, reduces the time of hospital care when compared with that for simple suturing, and appears preferable to methods of esophageal exclusion which often require a secondary surgical procedure.

[Signet-ring cell adenocarcinoma involving the bladder and the rectum. Apropos of two cases].

Two cases of primary signet-ring cell carcinoma involving the urinary bladder, with invasion of the rectum, are presented. Pelvic exenterations were performed, followed by a rapidly fatal outcome (6 and 7.5 months). These cases of signet-ring cell carcinoma of the bladder were reviewed with 33 previously reported cases in the literature. The clinical characteristics, histologic findings, pathogenesis, and effectiveness of aggressive treatment of this rare bladder malignancy are discussed.

[Familial form of primary cancer of the parathyroid glands. A disease entity or incidental association?].

Three cases of parathyroid neoplasms in familial hyperparathyroidism are reported. There were not associated with other endocrine glands or parathyroid glands lesions. Parathyroid gland carcinoma was diagnosed in 2 cases. Review of 7 cases of familial parathyroid carcinoma, diagnosed in 5 different families and issued from the literature, indicates that it can be associated to multiple endocrine neoplasia or other parathyroid lesions. The familial parathyroid carcinoma entity needs further studies before to be fully recognised.

[Linitis plastica of the stomach. Factors influencing prognosis].

The authors make a retrospective study of a series of 57 patients aged 63 years in average, followed up from 1979 to 1989 for linitis plastica of the stomach. Surgical exeresis was performed in 49 patients (34 total gastrectomies and 15 partial gastrectomies, including five 2/3 gastrectomies, two 3/4 gastrectomies, four 4/5 gastrectomies and four upper polar esogastrectomies). The overall actuarial survival rate (n = 57) was 62.5% at 1 year, 40% at 2 years and 12.5% at 5 years. The prognosis did not vary with the delay of diagnosis, the invasion of the area of resection, the associated tissue differentiation and the invasion of lymph nodes. It did very according to the height of the tumor: 22% survival at 5 years for tumors under 6 cm, against 0% for tumors exceeding 6 cm (p < 0.001).

Actuarial Analysis↗

[Cancer of the cardia. Prognostic factors and treatment].

Pronostic of carcinoma of the esogastric junction is worsened by the potential two-way route of spread in case of lymph node metastasis: mediastinum and abdomen. During the last 10 years the authors observed 71 cases of adenocarcinoma of the gastric cardia, including 7 cases of linitis plastica. Histopathologic and clinical follow-up data are presented. The aims of the study were to evaluate prognostic factors and to define the best surgical treatment. There were mainly elderly patients with a poor physical status. Ten patients did not undergo surgery (14%). Among 57 patients undergoing radial resection (80.3%), total gastrectomy and upper polar esogastrectomy were performed in respectively 29 and 28 cases. The carcinomas were truly located to the gastric cardia in only 37 cases (65%). Operative mortality was 12.3%, not depending of the surgical technique. All patients five-year survival rate was 10.2%, improving to 15% in case of curative resection. The value of lymph node metastasis (80.7% of the patients) as a prognostic factor depended of the proximal or distal localization of the nodes. A positive surgical margin (15.7% of the patients) was a poor prognostic factor with a 6.9 months mean survival. The authors conclude that an aggressive surgical approach is worthwhile, because of the carcinoma invasion (nodes, margin), but not always possible (poor physical status).

[Cystic dystrophy of aberrant pancreatic tissue in the duodenal wall. Diagnostic and therapeutic problems].

The authors report the case of a 28-year-old man with a cystic dystrophy of aberrant pancreatic tissue (C.D.A.P.T.) presenting with a history of major abdominal pain. First diagnosis was chronic pancreatitis because of clinical presentation, alcoholic intoxication, and the results of medical imaging techniques. A vagotomy associated with a gastroenterostomy was performed. Several years later the abdominal pain relapsed and failed to be cure by means of medical treatment. A duodenopancreatectomy was performed. Histology demonstrated the diagnosis of C.D.A.P.T. C.D.A.P.T. is a benign disease of the pancreas, limited to its cephalic portion, without demonstrated pathogenesis. C.D.A.P.T. can be either isolated or associated with a chronic pancreatitis. Clinical diagnosis can be particularly difficult as indicated by a literature review. Abdominal pain is the main symptom. Clinical presentation is rarely related to a complication (stenosis). Endoscopy, sonogram, and CAT scan are three techniques of diagnosis value, but intraluminal-sonography is more efficient. Tumor excision is not recommendable. Treatment of C.D.A.P.T. by duodeno-pancreatectomy (D.P.) is often indicated because of concurrent chronic pancreatitis or suspected pancreatic carcinoma. In case of clinical diagnosis of C.D.A.P.T., fenestration of the cysts under endoscopic control is the only local treatment that can avoid D.P.

[Leiomyosarcomas of the rectum. Amputation of the rectum or local resection?].

Two cases of high grade leiomyosarcoma of the rectum treated by local excision are reported. The first patient presented a local recurrence associated with liver and pulmonary metastases and eventually died, respectively 11 and 22 months after resection. The second patient's tumor recurred 3 months after excision and was treated with pelvic exenteration and CYVADIC regimen as chemotherapy and died 3 years later from local recurrence. A review of the literature indicates that local surgical excision in comparison to a more radical surgical approach, such as abdominoperineal resection, is as effective in improving survival. Lesions less than 2.5 cm in diameter, confined to the bowel can be treated by local surgical excision. To date no adjuvant therapy is effective in terms of survival or local control.
