Cystic neoplasms of the pancreas: a series.

MATERIAL AND METHODS: a series of 23 cases with cystic pancreatic neoplasms studied and treated between December 1977 and December 2001 out of 297 cases of pancreatic neoplasms is presented. RESULTS: 16/23 were true pancreatic cystic neoplasms: 9 microcystic adenomas and 6 mucinous cystoadenoma type. There were also 2 hydatid cysts, 1 lymphangioma, 2 cases of tuberculosis involving de pancreas, 1 lymphoma and 1 papillary cystic tumor type. CONCLUSIONS: true cystic tumors of the pancreas accounts for 5,8% of the neoplasms studied in our hospital.

Colonic volvulus.

OBJECTIVE: To review the incidence of volvulations in our workplace, to study the procedures employed in its treatment, and to discuss our results during the last 20 years. MATERIAL AND METHODS: A series of colonic volvulus treated between 1978 and 1998 at one hospital is presented. RESULTS: We reviewed 41 cases. Volvulus locations are: sigmoid colon: 21, caecum: 17, transverse colon: 2, and splenic flexure: 1. Mortality rates according to the type of volvulus and type of operative procedure is analyzed. Four cases of volvulus recurrence (9%). CONCLUSIONS: Treatment guidelines for the approach to colonic volvulus are presented.

[Splenosis: underdiagnosed entity].

OBJECTIVE: To report a case of renal splenosis in a patient that had previously undergone splenectomy due to traumatic rupture. METHODS/RESULTS: A 42-year-old patient consulted for pancreatitis. A CT scan disclosed a mass behind the tail of pancreas, MRI assessment with gadolinium enhancement showed a left renal mass which was surgically resected. Histopathological analysis of the surgical specimen demonstrated splenic tissue. CONCLUSIONS: Splenosis should be considered in splenectomized patients with lesions compatible with tumors and should be distinguished from hyperplasia of accessory spleens.

Preoperative platelet count in pancreas cancer: a prognostic factor?

AIM: To determine whether preoperative platelet count influenced the prognosis for surgical treatment of pancreas cancer. METHODS: Retrospective study of 144 patients operated on for pancreatic cancer: 49 with adenocarcinoma, operable with curative intent (group A), 86 in whom palliative resection or bypass was done (group B), and 9 in whom exploratory laparotomy was done. Preoperative platelet count was done for all patients. Groups A and B were divided into 2 subgroups (> 200,000 platelets/mm3 and < 200,000 platelets/mm3), and an additional subgroup was established for patients with > 300,000 platelets/mm3. Survival was analyzed in the resulting subgroups. RESULTS: Among patients who underwent curative resection, statistical analysis revealed significantly better survival (p < 0.05) in patients with a platelet count > 200,000 platelets/mm3 and a very significant difference (p < 0.01) in the 300,000 platelets/mm3 subgroup. No differences were found in the subgroups of patients who underwent palliative surgery. CONCLUSION: Preoperative platelet count may represent a prognostic factor in patients with pancreatic cancer operated on with curative intent. Our findings justify the need for clinical trials of antiangiogenic therapy.

[Reversible partial paraplegia after sympathetic lumbar block].

We describe a case of left sided paraplegia after chemical lumbar sympathectomy in which recovery was nearly total. The cause was probably an ischemic myelopathy due to spasm or damage to Adamkiewicz's radicular artery after puncture or direct infiltration during the procedure.

[Prognostic significance of delayed cutaneous reactivity in 5-year survival in colorectal cancer: a prospective study].

A series of 84 patients operated on for colorrectal cancer-Duke's stages A:6, B:22, C:51 and D:5- are studied prospectively and with a 5 year follow-up. All of them were treated in the same hospital and with identical criteria during a period of time of two years. Immunoglobulins (A, G, M) and skin reactivity measured through a multiantigen device were determined preoperatively and at 48 hours and 30 days after operation. Data analysis was done once real survival at 5 years was known. Immunoglobulins changes showed no significance in relation to survival in this series. Preoperative skin reactivity values measured in mms demonstrated prognostic significance for patients in stage C when considering survivors -p < 0.05- and decreased -p < 0.01- at five years. Numerical values of skin reactivity done with a delayed hypersensitivity multiantigen compound may represent and additional prognostic factor to be considered in advanced colorrectal cancer patients.
