RESUMO

BACKGROUND/AIM: Distal gastrectomy (DG) represents the only curative treatment for most mid-lower gastric cancers (GCs). As of 2017, however, no reconstructive modality to conduct after DG has gained unanimous consensus. Additionally, most authors have investigated Billroth 1 and Roux-en-Y (RY) rather than Billroth 2 (B2) reconstruction. We analyzed B2 and RY gastrojejunostomy to identify the preferable technique and augment the available information on B2 restoration. PATIENTS AND METHODS: We retrospectively selected 132 GC patients who were consecutively submitted to DG at our institution between April 2005 and February 2016. B2 and RY anastomosis were accomplished as methods of reconstruction (respectively 36 and 96 cases). We compared these techniques in terms of clinicopathological, surgical, postoperative and oncologic outcomes. RESULTS: Compared to RY gastrojejunostomy, B2 reconstruction was significantly associated with a greater mean number of harvested lymph nodes (26.03 vs. 21.65, p=0.045) but also with a longer hospital stay (22.8 vs. 15.7 days) (p=0.022) and higher readmission rate (28.57% vs. 3.1%, p<0.0001). On multivariate analysis, reconstruction method was the most significant independent prognostic factor for hospital readmission. CONCLUSION: In light of our results, we propose that B2 gastrojejunostomy deserves more study in order to better identify the best post-DG anastomosis.

RESUMO

Differences in postoperative outcome and recovery between patients subjected to laparoscopic-assisted versus open surgery for colorectal cancer (CRC) resection have been widely documented, though not specifically for right-sided tumors. We investigated the immunological responses to the different surgical approaches, by comparing postoperative data simultaneously obtained at systemic, local and cellular levels. A total of 25 right-sided CRC patients and controls were managed, assessing -in the immediate followup- the conventional perioperative parameters and a large panel of cytokines on plasma, peritoneal fluids and lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMC) tissue cultures. A general better recovery for patients operated with laparoscopy compared to conventional procedure, as indicated by the analysis of typical pre- and post-surgical parameters, was observed. The synchronous evaluation of 12 cytokines showed that preoperative plasma levels of the proinflammatory cytokines IL-6, IL-8, IL-1ß, TNFα were significantly lower in healthy donors versus CRC patients and that such differences progressively increase with tumor stage. After surgery, the IL-6 and IL-8 increases were significantly higher in open compared to laparoscopic approach only in CRC at early stages. The postsurgical whole panel of cytokine levels were significantly higher in peritoneal fluids compared to corresponding plasma, but with no significant differences depending on kind of surgery or stage of disease. Then we observed that, pre- compared to the corresponding post-surgery derived LPS-stimulated PBMC cultures, produced higher supernatant levels of the whole cytokine panel. In particular IL-6 in vitro production was significantly higher in PBMC derived from patients subjected to laparoscopic versus open intervention, but -again- only in CRC at early stages of disease. Our results thus show that laparoscopy compared to open right resection is associated with a shorter compromission of the immunological homeostasis, mainly in early stages of right-CRC patients.

RESUMO

The purpose of this study is to verify the usefulness of a multidisciplinary Trauma Registry in the evaluation of trauma, particularly in relation to the number of specialists involved, and to analyze the effective role of the general trauma surgeon in an integrated trauma care system. The present study was performed by analyzing data from the Trauma Registry of the University Hospital Sant'Andrea in Rome, which was set up in March 2006. Data recorded between March 2006 and March 2009 was considered for the present study. The severity of trauma was categorized by dividing patients into 4 subgroups based on the value of ISS: minor injuries (ISS 1-8), moderate (ISS 9-15), severe (ISS 16-24) and very severe (ISS> 24). Patients who had an ISS greater than 9 were taken into account for further analysis and comparison. To evaluate the significance of the multidisciplinarity the patients were stratified in subgroups considering the number of specialists involved in relation to the anatomic location of injuries. In the 1386 trauma patients entered in the registry, the mean and median ISS value were 10.7 ± 8.4 and 9 respectively. The overall mortality and morbidity were 4.1% and 7.4% respectively. There was a statistically significant linear relationship between the number of specialists involved and the ISS (multidisciplinarity / ISS r = 0.493, p <0.001). Patients with ISS greater than 9 were 358, 25.8% of all cases. The mean ISS was 21.4 ± 10.3. Mortality and morbidity rates were 9.8% (35 patients) and 22.1% (79 patients) respectively. The average number of specialists involved was 2.4 ± 1.1, median 2 (range 1- 6). Results confirmed the significance of the multidisciplinary treatment for patients with trauma and the central role played by the general surgeon.

RESUMO

BACKGROUND: The shortage of essential surgical care in sub-Saharan Africa is a worldwide problem. Lack of healthcare workers, surgeons and very limited resources are the reason for this critical health crisis. Furthermore in Africa many physicians as soon as they get a degree emigrate in more attractive countries. METHODS: "Multidisciplinary teaching support to a new Faculty of Medicine in N'Djamena - Chad" is a teaching cooperation program between «Sapienza¼ University of Rome and the University Hospital "Le Bon Samaritain" in N'Djamena, Chad. The project started in 2010, with the aim of cooperating in teaching medical students of African origin and in training Italian residents in sub-Saharan surgical and internal pathologies. In Chad the greatest surgical burden (about 11% of the total global diseases) is created by injuries, cancers, congenital anomalies, appendicitis, bowel obstructions, hernias, abscesses (by amebiasis or others) and obstetric emergencies. CONCLUSIONS: Up till now healthcare in Africa especially in rural areas has been provided by international organisations,we believe that academic collaborations between high-income and low-income Nations is necessary to meet the real needs of the african surgical workforce; at the same time it is very useful for store of knowledge of our residents.

RESUMO

BACKGROUND: Laparoscopic left lateral sectionectomy (LLS) has gained popularity in its use for benign and malignant tumors. This report describes the evolution of the authors' experience using laparoscopic LLS for different indications including living liver donation. METHODS: Between January 2004 and January 2009, 37 consecutive patients underwent laparoscopic LLS for benign, primary, and metastatic liver diseases, and for one case of living liver donation. Resection of malignant tumors was indicated for 19 (51%) of the 37 patients. RESULTS: All but three patients (deceased due to metastatic cancer disease) are alive and well after a median follow-up period of 20 months (range, 8-46 months). Liver cell adenomas (72%) were the main indication among benign tumors, and colorectal liver metastases (84%) were the first indication of malignancy. One case of live liver donation was performed. Whereas 16 patients (43%) had undergone a previous abdominal surgery, 3 patients (8%) had LLS combined with bowel resection. The median operation time was of 195 min (range, 115-300 min), and the median blood loss was of 50 ml (range, 0-500 ml). Mild to severe steatosis was noted in 7 patients (19%) and aspecific portal inflammation in 11 patients (30%). A median free margin of 5 mm (range, 5-27 mm) was achieved for all cancer patients. The overall recurrence rate for colorectal liver metastases was of 44% (7 patients), but none recurred at the surgical margin. No conversion to laparotomy was recorded, and the overall morbidity rate was 8.1% (1 grade 1 and 2 grade 2 complications). The median hospital stay was 6 days (range, 2-10 days). CONCLUSIONS: Laparoscopic LLS without portal clamping can be performed safely for cases of benign and malignant liver disease with minimal blood loss and overall morbidity, free resection margins, and a favorable outcome. As the ultimate step of the learning curve, laparoscopic LLS could be routinely proposed, potentially increasing the donor pool for living-related liver transplantation.

RESUMO

We describe a case of gastric metastases from a lobular carcinoma of the breast in a 73-year-old woman who had undergone a left mastectomy with axillary dissection 15 years earlier. The initial diagnosis was diffuse-type gastric carcinoma as evaluated both by analysis of gastric biopsy findings and ultrasonographic endoscopy. The definitive diagnosis of metastatic breast cancer was confirmed after subtotal gastrectomy for a presumed primary gastric carcinoma and was obtained using a panel of specific immunohistochemical markers. The distinction between primary and secondary gastric malignancies in patients with a history of lobular breast carcinoma may not be merely an academy exercise, since the treatment and prognosis of the two situations are different.

RESUMO

Breast cancer in men is an uncommon disease. Because of its rarity little is known about its aetiology, clinical behaviour and treatment. Retrospective studies show that when age- and stage-matched breast cancer in men and women are compared, there is no difference in survival between the two groups. Nevertheless, because of the absence of screening protocols and the limited amount of mammary tissue in men, allowing rapid local infiltration, a late diagnosis is often made, with a poor survival rate. Most of our current knowledge about the biology, natural history, surgical therapeutic strategies, adjuvant radiotherapy and chemotherapy protocols of male breast carcinoma has been extrapolated from its female counterpart. The Authors report the case of a male patient with breast cancer and pagetoid diffusion in the nipple region, and, on the basis of a review of the literature, summarise what is currently known about this rare neoplasm in terms of prognostic factors, therapy and survival.

RESUMO

Gastrointestinal stromal tumour: report of a case as a model of surgical and pharmacological therapy of solid tumours. mutation of this protein is present in most of these tumours. Gastrointestinal stromal tumours are notoriously unresponsive to chemotherapy and radiotherapy and prior to the recent introduction of the kit inhibitor imatinib, there was no effective therapy for advanced, metastatic disease. We report a case of metastatic gastrointestinal stromal tumour located primarily in the ileum and examine it in detail in order to contribute both to identifying factors capable of predicting its clinical course and evaluating the efficacy of imatinib as adjuvant therapy for this rare type of tumour. We share the opinion that, given the present state of the art, surgical resection remains the gold standard of treatment for these tumours and imatinib is a valid systemic therapy for metastastic and locally unresectable gastrointestinal stromal tumours.
