RESUMO
BACKGROUND: Standard oncologic liver resections performed on elderly patients (≥70 years old) have been shown to be safe and effective. The aim of this study was to analyze operative and oncologic short-term outcomes of totally laparoscopic liver resections (TLLR) performed on elderly patients for malignancies. METHODS: We performed a retrospective statistical analysis of prospectively recorded data of TLLR performed from October 2008 to February 2012 by a single hepato-pancreato-biliary (HPB) surgeon. Patients were divided into two groups according to age (<70 vs. ≥ 70 years old) and perioperative outcomes were compared. RESULT: A total of 60 TLLR for malignancies were identified of which 25 patients (42 %) were aged ≥ 70 years (Group A) and 35 (58 %) were aged <70 years (Group B). There was no difference in operative time (170 vs. 180 min, p = 0.267), median blood loss (200 vs. 250 ml, p = 0.183), number and time of Pringle maneuver (p = 0.563 and p = 0.180), blood transfusion rate (4 vs. 17 %, p = 0.222), conversion rate (4 vs. 9 %, p = 0.443), morbidity rate (12 vs. 20 %, p = 0.797), and perioperative mortality rate (0 vs. 3 %, p = 0.688). An R0 resection was achieved in 92 (Group A) versus 83 % (Group B) (p = 0.265). At a median follow-up of 18 months, 12 % of patients in Group A experienced a disease recurrence with a related mortality rate similar to that of Group B (8 vs. 12 %, p = 0.375). CONCLUSION: This retrospective comparative study shows that TLLR performed on elderly for liver neoplasm are feasible and safe and lead to short-term outcomes similar to those of younger patients.

BACKGROUND: Intestinal microbiota dysbiosis may enhance the carcinogenicity of colon cancer (CC) by the proliferation and differentiation of epithelial cells. Oral Fusobacterium nucleatum (Fn) and Porphyromonas gingivalis (Pg) have the ability to invade the gut epithelium, promoting tumor progression. The aim of the study was to assess whether the abundance of these odontopathogenic bacteria was associated with colon cancer. We also investigated how lifestyle factors could influence the oral Fn and Pg abundance and CC. METHODS: Thirty-six CC patients were included in the study to assess the Pg and Fn oral and colon tissue abundance by qPCR. Oral health data, food habits and lifestyles were also recorded. RESULTS: Patients had a greater quantity of Fn in the oral cavity than matched CC and adjacent non-neoplastic mucosa (adj t) tissues (p = 0.004 and p < 0.001). Instead, Pg was not significantly detected in colonic tissues. There was an association between the Fn quantity in the oral and CC tissue and a statistically significant relation between the Fn abundance in adenocarcinoma (ADK) and staging (p = 0.016). The statistical analysis revealed a tendency towards a greater Fn quantity in CC (p = 0.073, η2p = 0.12) for high-meat consumers. CONCLUSION: In our study, Pg was absent in colon tissues but was correlated with the oral inflammation gingival and plaque indices. For the first time, there was evidence that the Fn oral concentration can influence colon tissue concentrations and predict CC prognosis.
RESUMO
AIM: The cost effectiveness of the laparoscopic right hemicolectomy is still debated, and the current literature does not allow to be drawn certain conclusion. Our study compared direct clinical costs and outcomes for laparoscopic right hemicolectomy with the two most used type of anastomosis, such as ExtraCorporeal Anastomosis (ECA) and IntraCorporeal Anastomosis (ICA). MATERIAL AND METHODS: In this retrospective study, all patients who underwent laparoscopic right hemicolectomy with intracorporeal and extracorporeal anastomosis between January 2016 and April 2018 were evaluated. Patients were divided into two groups according to the type of anastomosis: ECA or ICA. RESULTS: Thirty ECA and twenty-nine ICA patients were included in the study. Operative time was significantly longer in ICA group than ECA group (p < 0.001). No significant differences between the groups were seen in terms of timeto- first flatus, postoperative complications and re-admission rate. ICA group showed a shorter hospitalization (5 vs 6; p < 0.022). In the ICA group, considering only the surgical tools were more expensive than in ECA (1435.6 vs 72 ). Nevertheless, the total cost of the two procedures in similar (14451.36 in ECA group vs 14631.04 in ICA group). CONCLUSION: ECA and ICA are comparable in terms of postoperative outcomes. ICA requires much more expensive charges, compared to a minor hospitalization. The ECA seems to be less expensive in terms of surgical supplies but the longer recovery determines an increase in the total cost resulting in a non-inferiority of one compared to the other technique.

AIM: Pathological complete response (pCR) and clinical outcomes [overall survival (OS), disease-free survival (DFS), locoregional control (LC)] were evaluated in a single-institution experience of different schedules of neoadjuvant chemoradiotherapy (CRT) for patients with locally advanced rectal cancer (LARC). PATIENTS AND METHODS: Data for 322 patients with LARC were retrospectively analyzed. pCR was evaluated according to Mandard tumor regression grade (TRG). The Kaplan-Meier method was used to estimate OS, DFS and LC. RESULTS: Three hundred and three (94.1%) patients underwent surgery. pCR was observed in 81 patients (26.7%), with TRG1-2 rate of 41.8%. The 5- and 10-year OS, DFS and LC rates were 82.5%±2.5% and 65.5%±3.8%, 81.2%±2.4% and 79.3%±2.9%, 93.1%±1.7% and 90.5%±2.1%, respectively. CONCLUSION: Neoadjuvant CRT in LARC patients resulted in favorable long-term oncological outcomes, with a high pCR rate and acceptable toxicity.

AIMS AND BACKGROUND: Occult/obscure gastrointestinal bleeding is often problematic to diagnose. It often leads to delayed treatment, a particularly dangerous circumstance when tumor origins are involved. This study reports the six-year experience of an Italian Surgery Center in the identification of the nature (tumor versus non tumor) and site of origin (upper, middle, lower gastrointestinal tract) of occult/obscure bleeding requiring hospitalization, as well as in its treatment. METHODS: Diagnostic instrumental examinations employed were: esophagogastroduodenoscopy, rectocolonoscopy, computerized tomography small bowel follow-through examination, capsule endoscopy, biopsy, angiography, abdominal computerized tomography scans and ultrasound. Therapies included: interventional radiology and surgery. RESULTS: Thirty-five cases of obscure and 27 cases of occult bleeding were examined; all received a definite diagnosis during hospitalization. In the cases with obscure bleeding the diagnosis was inflammatory bowel disease (n = 7), angiodysplasia (5 gastric, 2 duodenal, 2 jejunal, 3 ileal, 4 right colon), small bowel tumors (4 non-Hodgkin lymphomas, 1 leiomyoma, 6 adenocarcinomas), and gastric metaplasia of Meckel's diverticulum (n = 1). There were significantly more nontumor lesions than tumors (P < 0.005), and a middle tract source was significantly more frequent than upper/lower tract sources (P < 0.0001). Intestinal resections were performed for all small bowel tumors (8 laparotomic, 3 laparoscopic), 5 angiodysplasias, all cases of inflammatory bowel disease and gastric metaplasia of Meckel's diverticulum; arterial embolization was performed for 11 angiodysplasias. In the cases with occult bleeding the diagnosis was sigmoid colon polyps in 6 (treatment, endoscopic polypectomy) and right colon cancer in 21 (treatment, right hemicolectomy). There were significantly more tumors than nontumor lesions (P < 0.0001); all derived from the lower gastrointestinal tract. In all cases, the interventions resolved the bleeding completely. CONCLUSIONS: The results show that more than 50% of cases with obscure/occult bleeding requiring hospitalization are motivated by malignant gastrointestinal tumors, 34% of which are located in the small bowel, usually a difficult tract to explore. Thanks to modern technology, however, their diagnosis and treatment can nowadays be promptly and successfully achieved.

PURPOSE: Our study is to demonstrate the feasibility and the safety of the Minilaparoscopic Cholecystectomy. MATERIAL OF STUDY: During one year period 12 patients underwent 5mm Laparoscopic Cholecystectomy and 102 patientunderwent Mini-laparoscopic Cholecystectomy. In this study the exclusion criteria for surgery have been analyzed as well as the technical difficulties, the operation time, the duration of hospital stay, the post-surgery pain, the complications and the aesthetic results RESULTS: The operation time was 3 minutes longer for Mini-laparoscopic Cholecystectomy, the hospital stay was shorter in Mini-laparoscopic group. Patients that underwent 5mm Laparoscopic Cholecystectomy required a longer analgesic therapy. Complications occurred during the study were not related to the method. The aesthetic results were better in Minilaparoscopic Cholecystectomy due to lower scars length. Only in two cases we converted the planned Mini-laparoscopic Cholecystectomy in 5mm Laparoscopic Cholecystectomy. DISCUSSION: All the patients submitted to Mini-laparoscopic Cholecystectomy and 5mm Laparoscopic Cholecystectomy had the same therapeutic result. The Mini-laparoscopic Cholecystectomy gave advantages on post-surgery pain and recovery time. CONCLUSIONS: In our experience the Mini-laparoscopic Cholecystectomy is a safe method that guarantees the same clinical results of conventional Laparoscopic Cholecystectomy. It shows some technical difficulties, but yet this surgery is to be recommended to expert surgeons. KEY WORDS: Gallbladder Polyps, Gallstone Disease, Mini-laparoscopic Cholecistecomy.
