Bilio-digestive double bypass for nonresectable pancreatic cancer.

In spite of extensive preoperative investigation, surgical exploration is often the only way to determine whether a pancreatic cancer is curatively resectable. If curative resection is not possible, palliation of cholestasis and eventual duodenal obstruction is mandatory. This is best achieved by construction of a bilio-digestive double bypass. Many different techniques have been described but considerable rates of delayed gastric emptying have added high morbidity to the procedure. We propose a retrocolic construction technique combining an omega loop with a Roux-en-Y reconstruction which to our knowledge has not been published before.

Arterial blood supply of the mesocolic areas. An anatomical and radiological study.

The authors report on first observations on the vascularization of the areae mesocolicae which resulted from radioanatomical studies made in collaboration with the Institute of General Clinical Surgery of the University of Siena. Three areae can be distinguished: colocolica (Treitz), sigmoidea or intersigmoidea, and intercolica. The investigations were carried out using selective preoperative angiography and the injection of anatomical preparations.

[Arterial anatomy of the sigmoid colon useful for colon take down techniques].

BACKGROUND: An anatomic study about the arterial vascularization of the sigmoid was performed in order to obtain guidelines for the surgical treatment of rectal carcinoma. AIM: In the proposed technique, the sigmoid is brought down to the perineum, after radical anal-rectal resection, including sphincterectomy. MATERIAL AND METHODS: Thirty-three anatomical pieces were obtained through in situ dissection of formolized corpses (22 were male and 11 female). Turpentine solution, red marking, polyvinyl chloride were the materials used for preparation after catheterization of the inferior mesenteric artery. RESULTS: The inferior mesenteric artery originated in most cases from the left side of the abdominal aorta, approximately 4.3 cm fromits bifurcation point; the left colonic artery, in 25 cases, originated straight from the inferior mesenteric artery below the left colonic artery, after which the sigmoid would be brought down to the perineum. CONCLUSION: Knowledge about arterial vascularization of the sigmoid could be helpful in the surgical management of rectal cancer.

Regional lymph node metastases in carcinoma of the left side of the colon and rectum: CT demonstration.

The distribution of regional lymph node metastases in carcinoma of the left side of the colon, rectum, and anus can be well shown by routine CT of the abdomen and pelvis. Recognition of the location of nodes in the mesocolic, left colic, and IMA nodal groups can help in developing a systematic approach to the detection of nodal metastasis. This can be especially important in preoperative planning for cases in which resection may be curative. In addition, an understanding of the distribution of nodal metastasis will make it possible to recognize early recurrent nodal disease, particularly with an increase in associated increase in levels of carcinoembryonic antigen, and to predict certain clinical sequences such as hydronephrosis of the left kidney associated with left colic nodal metastases.

Mesocolic myxoid hamartoma showing neural differentiation: an ultrastructural and immunohistochemical study.

A myxoid mesocolic tumor in a 4-month-old female infant is described. The tumor weighed 190 g and measured 8 cm in diameter and presented as a single mass composed of stellate and round cells with vesicular nuclei and prominent nucleoli in a myxoid, well-vascularized stroma. Electron microscopy showed mesenchymal cells with dilated rough endoplasmic reticulum, cell projections with primitive and desmosome-like cell junctions, and basal membrane-like material. Immunohistochemical studies demonstrated immunoreactivity with antibodies against vimentin and S-100 protein. The infant is well and without evidence of disease 3 years after surgery. This is an example of a peripheral myxoid hamartoma with neural differentiation, and the tumor is expected to have a benign clinical course.

[Ischemic risk in the case of celiac trunk occlusion in patients undergoing pancreatodeodenectomy. Multicenter study and review of literature].

OBJECTIVES OF THE STUDY: To assess the risk of ischemia in patients undergoing pancreatoduodenectomy and presenting celiac trunk occlusion. METHODS: Multicenter survey and review of the literature. PATIENTS: We collected data from 22 patients (15 males and 7 females), with a median age of 66 years. Indication for pancreatic resection was adenocarcinoma of the head of pancreas (N = 9), other peri-ampullary tumors (N = 7) and chronic pancreatitis (N = 6). Trial clamping of the gastroduodenal artery was performed in 16 patients and was found to be positive in 9, who underwent a revascularization procedure. Among 6 patients who did not undergo trial clamping, 4 developed ischemia during pancreatic resection and unplanned revascularization had to be performed. Five patients developed complications (morbidity = 23%), which were fatal in 2 cases (mortality = 9%). Prevalence of celiac trunk occlusion has been estimated at 2-3% of all pancreatoduodenectomies. CONCLUSIONS: The risk of supra mesocolic ischemia by obstruction of the coeliac trunk is low, but can be minimized by performing trial clamping of the gastroduodenal artery. Revascularization should be performed if trial clamping induces a reduction of blood flow.

Technical details in the surgical correction of extrahepatic biliary atresia.

As in any new operation, what appear to be minor variations in surgical methods may be crucial to the success or failure of the procedure. Extended biliary drainage has been achieved in infants with extrahepatic biliary atresia by adherence to the details of the surgical technique just described. To date, results appear to be better in those infants having the definitive operation at the time of the initial exploration. Consequently, it appears that surgeons undertaking operative exploration should be able to carry out the porticoenterostomy procedures.

[Total mesorectal excision and preoperative radiotherapy in patients with rectal carcinoma: good preliminary results].

The value of a short course of radiotherapy prior to total mesorectal excision was studied in patients with resectable rectal cancer. The new surgical technique of total mesorectal excision was introduced under appropriate supervision and gave favourable treatment results. The incidence of local recurrence was markedly reduced by preoperative radiotherapy. Long term results should give greater insight into potential improvements in survival rates and any late side effects which may arise as a result of the radiation schedule.
