Iliac atherosclerotic occlusive disease complicating radiation therapy for cervix cancer: a case series.

BACKGROUND: Diagnosis and management of atherosclerotic occlusive disease complicating radiation therapy for squamous carcinoma of the cervix (SCC) are not well known. CASES: A series of four patients who underwent medical or surgical treatment of radiation-induced artery disease were identified. Chronic right iliac artery occlusion was seen in one patient 7 years after external irradiation for SCC and was treated by a femorofemoral bypass. Acute arterial occlusion was seen in three patients. One patient developed right foot ischemia 2 years after external irradiation for SCC which was treated by a right axillofemoral bypass. One patient developed a left toe necrosis 2 years after external irradiation for a recurrence of SCC which was treated by a percutaneous artery dilatation. One patient developed, 3 years after external irradiation for SCC, a subacute ischemia of the left leg on the first postoperative day after a rectal resection. It was treated by vasodilators, calcium inhibitors, and anticoagulants. CONCLUSIONS: Diagnosis of radiation-induced atherosclerotic occlusive disease complicating radiation therapy for SCC is easy but treatment is difficult. Long-term results of arterial dilatation are limited and extraanatomic bypass with allograft is the treatment of choice whenever feasible. However, because of poor long-term results, surgery should be attempted only in the case of severe ischemia.

[Para-esophageal hiatal hernia with acute gastric volvulus].

We report 3 observations of acute gastric volvulus on paraesophageal hiatus hernia requiring emergency laparotomy. The main characteristics of this complication of hiatus hernia are described and the importance of early diagnosis, because of unfavorable prognosis, is stressed.

[Pedicular clamping in major hepatectomies: clamping "of principle" or "of necessity"? A comparative study].

Fifty-two consecutive patients undergoing major hepatic resection for liver tumor were divided into two groups according to the operative procedure. Group A consisted of 34 patients in whom vascular inflow occlusion was performed "de principle" during parenchymal division and intrahepatic approach of the portal structures; the mean duration of the portal triad clamping was 43 mn (ranged 17 to 70 mn). Group B patients (18 cases) had hilar division of the structures of that portion of the liver due to be removed, prior to parenchymal division was performed without vascular arrest, except in five "de necessitate" cases during 5 to 22 mn. Groups A and B were comparable in terms of patient age or status, of king of liver tumors and extent of resection. Mean operating duration (215 vs 263 mn), volume of intraoperative blood transfusion (557 vs 1019 ml), intensive care (2.5 vs 4.2 days) and total hospital stays (19.6 vs 30.5 days) were significantly reduced in group A. A higher but transient increase of amino-transferase level was the only biochemical consequence of liver ischemia in group A, whereas postoperative disturbance in serum bilirubin, prothrombin time, fibrinogen, and total protein were significantly greater in group B, probably because of the greater volume of blood transfusion in this group. Thus, routine vascular inflow occlusion with transhepatic approach of the portal structures may be an effective and innocuous procedure for major liver resection.

[Hemobilia caused by biliary cyst].

Recurrent angiocholitis attacks occurred in an 80-year-old woman, and repeated investigations could not provide any diagnosis. Subsequently, the patient developed haematemesis. Angiography revealed haemobilia from an intrahepatic cause. Surgical constatations and pathological examination of the resected specimen revealed that haemobilia was due to a non-parasitic cyst of the liver. In this case, haemobilia resulted from two unusual complications of this hepatic lesion: intra-cystic bleeding and communication with an intrahepatic duct. Haemobilia has never been reported as a complication of non-parasitic cyst of the liver.

[Cystic lymphangioma of the adrenal gland. Three misleading cases].

Three cases of adrenal cystic lymphangioma are reported. In 1 patient the lesion was complicated by intracystic haemorrhage. The remaining 2 patients had a hepatic lesion which was treated in the same surgical operation as the adrenal cyst. Ultrasonography and computerized tomography play a major role in the exploration of these cysts. Their unexpected discovery has become more frequent since these methods have multiplied, and this raises therapeutic problems. The nature of adrenal cysts is determined at histology. In asymptomatic cysts percutaneous needle aspiration can only have an indicative value.

A report of forty-four instances of pancreaticoduodenal resection in patients more than seventy years of age.

Between January 1970 and December 1990, 223 patients underwent pancreaticoduodenal resection for pancreatic or periampullary tumors. Forty-four of these patients were 70 years of age or older and 179 patients were less than 70 years of age. In the older group, 27 patients were operated upon after 1986. The overall operative mortality rate was 9.0 percent and 2.5 percent during the last five years. The overall operative mortality rate was 4.5 percent in patients more than 70 years of age and 10 percent in those less than 70 years of age. The overall operative morbidity rate was 35 percent; 36 percent in patients more than 70 years of age and 35 percent in those less than 70 years of age. Survival was related to tumor histologic factors. For carcinoma of the pancreas, the survival rate at five years was 17 percent in patients more than 70 years of age and 19 percent in patients less than 70 years of age. For the ampullary carcinoma, the survival rate at five years was 38 percent in patients more than 70 years of age and 45 percent in patients less than 70 years of age. It can be concluded that, in a selected group, age is not a limiting factor for pancreaticoduodenal resection.

[Survival after gastrectomy for cancer. 209 cases].

The long-term results of 209 gastrectomies performed for adenocarcinoma, including 117 which were prospectively collected, are presented. Resection was curative in 154 cases (73.6 percent). The TNM distribution of the tumours was: stage I (TxNOMO) 75 cases, stage II (TxN1MO) 46 cases, stage III (TxN2MO) 33 cases and stage IV (TxNxM1) 55 cases. Lymph node involvement was more frequent in the prospective than in the retrospective study. With a more than 5 years' follow-up of 80 percent of the patients operated upon, the actuarial survival rate at 5 years (operative mortality included) was 38 percent for all lesions, 52 percent for curative resection and 2 percent for palliative resection. Following curative resection, the survival rates for tumours of the upper, middle and lower thirds of the stomach were 40, 60 and 55 percent respectively. These rates were 60 percent for stage I tumours, 54 percent for stage II tumours and 25 percent for stage III tumours. The results obtained in this series, where most of the curative gastrectomies included excision of N1 and N2 lymph nodes, show that lymph node involvement has no significant importance for the prognosis when it is proximal (N1) and is not incompatible with prolonged survival when it is pedicular (N2).

[Cancer of the pancreas. A plea for resection. 162 operated patients].

Between 1970 and 1990, 162 patients with carcinoma of the pancreas or the periampullary region were operated upon. A prospective study was conducted in 85 of them who underwent surgery after 1983. The tumour was resected in 63 patients (ductal adenocarcinoma in 43, periampullary carcinoma in 20). Biliary and/or gastrointestinal bypass was performed in 76 patients, and exploratory laparotomy in 23. The operative mortality rate was 3 percent (2/63) among patients with resection and 24 percent (24/99) among those with laparotomy with or without bypass. The longest survival (median: 33 months) was obtained in patients with periampullary tumours; it was 12 months after resection in patients with ductal adenocarcinoma and 4 months in the other cases. The preoperative estimate of unresectability was erroneous in 36.5 percent of the cases. Periampullary tumours were diagnosed only after pathological examination of the lesion removed in 47 percent. These results are in favour of radical surgery, especially since the operative mortality of resection is low and since resection, even palliative, gives a better survival rate than mere bypass.

[Resection of the portal vein in pancreatectomy for cancer: technical considerations. Apropos of 4 cases].

Out of 150 carcinomas of the pancreas operated from 1970 through 1989, 50 pancreatectomies were performed, including 4 cases of segmental resection of portal vein with total pancreatectomy (2 cases) or duodenopancreatectomy (2 cases). The technical procedure is described and discussed. Segmental resection of portal vein is rare in our experience and has been always performed out of necessity because of the over estimation of the resectability. However, mortality and post-operative stay are not increased.

[Severe hepatic trauma. Initial non-operative treatment. A case report].

The emergency surgical treatment of severe hepatic traumas still carries a high mortality risk. We report a case of severe blunt trauma of the liver managed without surgery under CT guidance. This attitude--which does not exclude surgery as a later resort--requires haemodynamic stability of the patient, close monitoring in a surgical intensive care unit and repeated CT scans.

Surgical results of intrathoracic gastric volvulus complicating hiatal hernia.

From 1981 to 1988, 138 patients with hiatal hernia were treated surgically at our centre. Twenty-one (mean age 76.6 years, 17 women, four men) had an associated intrathoracic gastric volvulus. Eleven patients (mean age 73.2 years), of whom eight were asymptomatic, had an elective procedure. Ten patients (mean age 80.3 years) had emergency surgery, six for acute complications of the volvulus (five cases of strangulation and one of perforated ulcer) and four because of other, unrelated causes of acute abdomen. There were four deaths after operation, all in the emergency surgery group. Four other patients had significant morbidity, all in the emergency group. In the elective cases, all hernias were easily reduced. In one emergency case a gastrotomy was necessary for decompression, and in another gastrectomy was necessary because of gastric gangrene. Our results indicate the need for elective intervention when intrathoracic gastric volvulus is first diagnosed.

[Caustic rectal stenosis. Trans-anal resection using an EEA stapler].

An original treatment of caustic rectal stenosis due to abuse of analgesic suppositories is presented. The stenosis had been excluded by distal colostomy during 2 years before reconstruction of the circuit was attempted. Anatomically, the stenosis appeared as a complete diaphragm which could be recanalized by an EEA stapler for circular anastomosis, installed in two sites: endoluminal from the colostomy and perineal. After a 2-year follow-up, the anatomical and functional results are satisfactory.

Bleeding of the pancreatic stump following pancreatoduodenectomy for cancer.

BACKGROUND/AIM: The purpose of this study was to determine the characteristics of bleeding of the pancreatic stump after pancreatoduodenal resection with pancreatojejunal anastomosis. PATIENTS AND METHODS: Between February 1970 and December 1990, 223 patients underwent a Whipple resection for cancer. RESULTS: Twenty patients (9%) had post-operative hemorrhage. In 10 patients bleeding arose within the operative field and in the 10 later within the gastrointestinal tract. Six patients bled from the gastroenterostomy and 4 (1.7%) from the pancreatic cut surface. In all four severity of the hemorrhage required urgent relaparotomy. CONCLUSIONS: Diagnosis and hemostasis could be achieved through a jejunostomy near the pancreatic anastomosis. Two patients had pancreatic fistula,one of them died.
