PURPOSE:To assess whether deoxycholic acid (DOC) and lithocholic acid (LCA) administered in a period of six months in a concentration of 0.25% may have a carcinogenic role in mice colon. METHODS:The study used C57BL6 female mice divided into four groups. The control group received a balanced diet and the others received diets supplemented with 0.25% DOC, 0.25% LCA and 0.125% DOC+0.125% LCA, respectively. After euthanasia, the lesions found in the resected gastrointestinal tracts were stained with hematoxylin-eosin and examined microscopically. RESULTS:No gastrointestinal tract changes were observed in the control group, while hyperplastic Peyer's patches in the small intestine, flat adenomas with mild dysplasia and chronic colitis at the level of the colon were found in all three test groups. The colonic lesions prevailed in the proximal colon. The highest number of flat adenoma lesions (8), hyperplasia of Peyer's patches (25) and chronic colitis (2) were found in mice fed with diet and LCA. CONCLUSION:Precancerous or cancerous pathological lesions could not be identified. Instead, adenomatous colonic injuries occurred in a shorter period of time (six months), compared to the reported data.

Background: Rectal cancer management has as its main component the surgical treatment. The purpose of the paper is to point out the advantages and disadvantages of sphincter saving techniques, respecting the oncological principles. Material and method: A cross-sectional, retrospective study was performed on a group of 69 patients admitted and surgically treated for rectal cancers in the Surgical Clinic I of the County Emergency Clinical Hospital of Tîrgu Mureș, for a period of one year (April 2012 -April 2013 and to whom rectal resections were performed. We followed the immediate postoperative evolutions in these patients, making a comparative analysis between those with the sphincter saving surgery and those in which other operations were performed. Results: From the total of 69 patients diagnosed with rectal cancer, sphincter saving procedures with restoration of digestive continuity by coloanal anastomosis were performed in 12 patients (17.39%) using the peranal or transanal approach; in 42 patients (60.86%) anterior rectosigmoidian resections with low and very low colorectal anastomosis ("very low" Dixon procedure) were performed. In 15 cases (21.74%) the Miles type of rectal resections, using the abdomino-perineal way, were performed. Out of the 12 cases with peranal or transanal anastomosis, 4 cases had postoperative complications. Conclusions: Rectal resection procedures, which are restoring the digestive tract continuity using low anastomosis (colorectal, coloanal, peranal or transanal), are representing viable and "physiological" alternatives, if they respect the oncologic principles. In well selected cases, the immediate postoperative evolution is favorable, relieving the patient from the psychological and physical trauma due to the presence of a colostomy.

Hydatid cyst involving the spleen is a rare clinical condition (0.5-4%). We report a case of multi-parasitic infection in a 62 year old female (hydatid cyst and ascaris lumbricoides infestation), confirmed during surgery. The purpose of the paper is to emphasize on the rare association of the two parasitic infections, affecting two different organs (spleen and jejunum). The combined symptomatology of the two parasites could mimic an acute surgical abdomen.

This chapter deals with the emergency treatment of transverse colon cancer. The main complications that classify transverse colon cancer in an emergency setting are obstruction, perforation accompanied by localized or generalized peritonitis, and hemorrhage which may be occult or cataclysmic with hemorrhagic shock. We present the technical principles of radical surgical resection using embryological, anatomical, and oncological concepts. In this chapter we also discuss the principles of lymphadenectomy associated with complete excision of the mesocolon with high vascular ligation, in particular with T3 or T4 cancers requiring D2/D3 lymphadenectomy. The use of infrapyloric, gastro-epiploic, and prepancreatic lymphadenectomy is recommended due to the frequent metastases in these regional lymph nodes.

Rectal cancer is one of the most common types of cancer in both men and women. In recent years, the importance of magnetic resonance imaging (MRI) has greatly increased in the multidisciplinary treatment of patients with rectal cancer. MRI has a particularly important role in the most accurate preoperative staging of these patients, both in terms of assessing the local invasion of the tumor and in terms of assessing the status of pelvic lymph nodes. Many patients with rectal cancer, especially those in the advanced stage of the disease, in the preoperative period undergo neoadjuvant radio chemotherapy. The evaluation of the clinical response of these patients to neoadjuvant therapy is of crucial importance both in terms of personalized treatment and in terms of their prognosis. In this regard, MRI has its clearly defined role at present in evaluating the efficacy of neoadjuvant therapy, as well as in postoperative follow-up.

Background: In the literature there are a number of studies that suggest a possible correlation between cholelithiasis/cholecystectomy and colorectal cancer. The exposure of the colon mucosa to the action of bile acids that potentially have a carcinogenic effect due to the change in anatomy after cholecystectomy, seems to be the explanation of this association. The purpose of this paper was to search for such a correlation in our study group. Methods: We performed a retrospective cross-sectional study, analyzing the patients admitted to the First Surgical Clinic of the County Emergency Clinical Hospital Tîrgu Mureș, between January 1 st , 2005 -December 31 st , 2010. Analyzing the medical records, operation protocols and histopathological results, we paid attention to demographics, location of neoplasia, the time elapsed since the cholecystectomy to the discovery of neoplasia, histological types, trying to perform correlations between these parameters and the lithiasic factor. Results: Out of the 534 patients admitted and operated with the diagnosis of colorectal cancer, 15.6% (n = 83) showed a history of gallbladder stone affection. Most patients came from urban areas, the average age was 67.2 (range 39-88 years), females were more affected. The most common locations were: the sigmoid colon (26.5%), rectum (36.3%) and the most common histological form was moderately differentiated adenocarcinoma. Conclusions: Similar to other studies, our work suggests a slight increase in the incidence of colorectal cancer in patients that underwent a cholecystectomy, without drawing a fi rm conclusion. We deem it necessary to see if diet changes of the Romanian population affect this relationship.

Objective: Sphincter saving techniques in low rectal cancer represents a challenge for the surgeons in their attempt to preserve the sphincter function and also to respect the principles of oncological surgery, in order to improve the quality of the patient’s life. The paper’s aim is to compare different sphincter saving techniques in regards to the early postoperative results. Methods: An observational, retrospective study was performed on 76 patients (N = 76) operated for low rectal cancer in the Surgical Clinic no.1 of the Targu Mures Emergency Clinical County Hospital, between January 2010 and October 2014, to whom the rectal resection was followed by a primary restorative technique for preservation of the sphincter function. The immediate postoperative results after different types of sphincter saving procedures were analyzed and compared. Results: From the studied patients, in 41 cases (53.94%) an anterior rectal resection with low colorectal anastomosis was done („very low” Dixon procedure), for 29 patients (38.15%) a sphincter saving technique with a peranal anastomosis was performed and in 6 cases (7.89%) an intersphinteric rectal resection with coloanal anastomosis was made. Conclusions: Sphincter saving techniques, if oncological principles are respected, represents a viable option in the treatment of low rectal cancer and brings hope for improving the quality of the patients’ life.

Background: Incisional hernias are important complications of abdominal surgery. Normally they are followed by the growth of the hernia sac and an increase of the abdominal wall defect with loss of domain of the herniated organs. Case report: We report a case of a 51 year old female, admitted in the 1 st Surgical Clinic of the County Emergency Clinical Hospital of Tîrgu Mureș with a large median reducible incisional hernia and a wall defect of 10/12 cm. The abdominoplasty was performed using the Oscar Ramirez technique, which consists of a longitudinal incision along the aponeurosis of the external oblique muscle, at approximately 1-2 cm from the external edge of the rectus abdominis. This procedure allows the abdominal wall closure. This case is part of a lot of 4 patients who received this treatment using the aforementioned procedure in the past 2 months. Postoperative recovery was favorable, bowel movements were present on the second day after the surgery, the subcutaneous drains were shortened on the fi fth day and removed on the sixth. There were no immediate postoperative complications or up to a month after the surgery. The patient was discharged on the seventh day. Conclusions: This technique can be used alone in case of large abdominal wall defects, or prequeling an on-lay mesh procedure addressed to a weak abdominal wall, case in which the functional result is superior to a substitutional mesh.
