Anastomotic leaks after anterior resection for mid and low rectal cancer: survey of the Italian Society of Colorectal Surgery.

BACKGROUND: The aim of the survey was to assess the incidence of anastomotic leaks (AL) and to identify risk factors predicting incidence and gravity of AL after low anterior resection (LAR) for rectal cancer performed by colorectal surgeons of the Italian Society of Colorectal Surgery (SICCR). METHODS: Information about patients with rectal cancers less than 12 cm from the anal verge who underwent LAR during 2005 was collected retrospectively. AL was classified as grade I to IV according to gravity. Fifteen clinical variables were examined by univariate and multivariate analyses. Further analysis was conducted on patients with AL to identify factors correlated with gravity. RESULTS: There were 520 patients representing 64% of LAR for rectal cancer performed by SICCR members. The overall rate of AL was 15.2%. Mortality was 2.7% including 0.6% from AL. The incidence of AL was correlated with higher age (p<0.05), lower (<20 per year) centre case volume (p<0.05), obesity (p<0.05), malnutrition (p<0.01) and intraoperative contamination (p<0.05), and was lower in patients with a colonic J-pouch reservoir (p<0.05). In the multivariate analysis age, malnutrition and intraoperative contamination were independent predictors. The only predictor of severe (grade III/IV) AL was alcohol/smoking habits (p<0.05) while the absence of a diverting stoma was borderline significant (p<0.07). CONCLUSION: Our retrospective survey identified several risk factors for AL. This survey was a necessary step to construct prospective interventional studies and to establish benchmark standards for outcome studies.

[Ileal endometriosis. A clinical case and a review of the literature]. / L'endometriosi dell'ileo. Caso clinico e revisione della letteratura.

Ileal localization of intestinal endometriosis is not extremely rare, but there are always problems related to the preoperative diagnosis. Symptoms of intestinal endometriosis offer often problems to the surgeon in the differential diagnosis with many more pregnant illnesses like appendicitis, diverticulitis, inflammatory bowel diseases and abdominal neoplasms. The authors report a case of endometriosis of the ileum clinically mimicking Crohn's disease. Crohn's disease of the ileum is the most frequently reported illness that is considered in the differential diagnosis. The review of the literature shows that a correct preoperative diagnosis of endometriosis of the ileum is very seldom done. All common diagnostic tools are not able to resolve diagnostic doubts. Also during explorative surgery the diagnosis of endometriosis is not easy. The authors conclude that endometriosis of the ileum has to be more often considered as possible cause of common intestinal symptoms mimicking inflammatory bowel disease and that this illness induces to reevaluate the importance for a correct diagnosis of an accurate clinical history.

[Malignant anorectal melanoma: description of a clinical case and review of the literature]. / Mélanome malin ano-rectal: description d'un cas clinique et revue de la littérature.

Malignant ano-rectal melanoma is a rare pathology without characteristic symptoms. It is more frequent in females than in males (ratio 2:1) and represents 3-15% of anal canal tumours. A case of a woman who recently came to us complaining of painful defecation, tenesmus and rectal bleeding induced us to reconsider the diagnostic and therapeutic implications in ano-rectal melanoma. The low incidence of cases reported and the negative 5-year prognosis are due to late, often incidental, diagnosis during clinical observation for hemorrhoids, rectal polyps or rhagades, together with the aspecificity of the tumour symptoms. We hope our case report emphasizes the importance of conducting early diagnosis in patients at risk of ano-rectal melanoma.

Which kind of surgery in elderly people for colorectal cancer?

Colo-rectal cancers are of high incidence in elderly patients. Different clinical features and the peculiar behavior of the tumor may influence surgical results and should be considered in the decision making, when the surgeon has to decide whether to perform radical gut resection or less straining palliative procedures. In a retrospective study, 102 large bowel cancer patients are analyzed submitted to surgery in the period 1989-1994. Patients were divided in two age classes: Group A: above 70 years of age, 45 cases (44.2%); Group B: under 70 years of age, 57 cases (55.8%). Emergency surgery procedures were necessary in 35 patients (34.4%), 20 cases (57%) in Group A and 15 cases (43%) in Group B. Radical resections could be performed in 25 (37%) old patients, 67% of the cases underwent a curative resection. Perioperative mortality and surgical complication rates were significantly higher in Group A than in Group B. The technical and biological difficulties in performing radical curative resections, the high complication rates and the occurrence of negative results of treatments provide a reason for careful evaluation of the risk/benefit ratio in older patients, where less straining palliative therapies may sometimes offer similar results.

[Cystic lymphangioma of the retroperitoneum. A case report]. / Linfangioma cistico del retroperitoneo. Contributo clinico.

Cystic lymphangioma of the retroperitoneum is a primary mesodermal derived benign neoplasm, arising from retroperitoneal lymphatics. The Authors report a case of cystic lymphangioma of the retroperitoneum recently observed, and a review of the international literature registering 181 cases from 1958 up to nowadays. Retroperitoneal localization, sub-clinic evolution and the impossibility to preoperatively define the histological type of the tumour, in spite of the modern diagnostic techniques, explain the difficulties to reach a correct differential diagnosis. The authors conclude that surgery only allows to exactly localize the tumour, yet the definition of cystic lymphangioma is an histological goal.

[Carcinoma of the male breast]. / Il carcinoma della mammella maschile.

The Authors, after a brief review of the most important epidemiologic, etiologic, diagnostic and therapeutic problems related to male breast cancer, report their personal experience. They point out the importance of an early diagnosis in order to obtain satisfactory results, comparable to those achieved in female breast cancer treatment.
