    Summary A 68-year-old male underwent a right hepatectomy, resection of the biliary convergence, and a left hepatic jejunostomy for a Klatskin tumour. The postoperative course was complicated by biliary abscesses with relapsing bloodstream infections due to Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae (KPC-Kp). A 2-week course of combination antibiotic therapy failed to provide source control and the bacteraemia relapsed. Success was obtained with a regimen of tigecycline 100mg daily for 2 months, followed by tigecycline 50mg daily for 6 months, then 50mg every 48h for 3 months. No side effects were reported

    Aim During left-sided spleen-preserving pancreatectomy (SPLP), limitations of laparoscopy may require spleen sacrifice or conversion to maintain patient safety. The objective of our study is to compare surgical and functional outcomes of robot-assisted and pure laparoscopic SPLP in patients with benign or borderline lesions of the body/tail of the pancreas. Patients and methods This was a case-matched study: fifteen patients who had robotic SPLP (R-SPLP) were matched with 15 comparable patients who had pure laparoscopic SPLP (L-SPLP). The peri-operative variables (conversion rate, amount of bleeding, operation time, length of hospital stay, complications, mortality and readmission) as well as the spleen preservation rate were compared between the two groups, The European Organisation for Research and Treatment of Cancer QLQ-C30 (EORTC QLQ-C30) specific questionnaires were used in each arm after at least 1 year of follow up in order to evaluate quality of life (QoL). Results No R-SPLP was converted to conventional laparoscopy, hand-assisted laparoscopy, or open surgery whereas L-SPLP had a conversion rate of 13.3% (p=n.s.); also fistula formation (20% vs. 46%; p=n.s.) was higher in the laparoscopic group although not statistically significant. Mean operative time (220 vs. 279 min; p=0.027) was shorter and the spleen-preserving rate (fail/ success, 0/15 vs. 4/11; p=0.03) of R-SPLP was significantly better compared to L-SPLP. Moreover, length of hospital stay was significantly shorter in the R-SPLP group compared to the L-SPLP group (6.5 vs. 8.8 days; p=0.04). Post-operative high grade surgical complications occurred only in one L-SPLP patient (0% vs. 6.6%; p=n.s.). Quality of life scores were not significantly different between the two groups. Conclusions R-SPLP could provide an increased chance for spleen preservation and faster surgical procedure. Furthermore, fistula formation and conversion rate seem to be lower, reducing the length of the hospital stay. Our case matched study confirmed the potential peri-operative benefits of robotic assistance in this setting, however these benefits did not translate into a better quality of life at least one year post-operatively

    Background: Intersphincteric resection (ISR) with total mesorectal excision (TME) is an accepted technique for the surgical treatment of very low rectal cancer. Historically it is associated with a higher functional complication rate than the Double Stapling (DS) technique when performed with open or laparoscopic approach. The aim of this study was to compare the surgical, short-term oncologic and functional outcomes of robotic ISR TME (R-ISR-TME) with those of robotic low anterior resection TME with a double stapling technique (R-DS-TME). Methods: Between April 2010 and December 2013, 42 patients underwent robot-assisted rectal resection with TME at our General Surgery Unit, including 10 R-ISR-TME. The outcomes of the R-ISR-TME group were compared with a R-DS-TME group selected using a case-matched methodology. We evaluated the operative, pathological, short-term oncologic results and postoperative sexual, urinary and defecation functions using specific questionnaires. Results: The analyses of the data showed similar results for R-ISR-TME and R-DS-TME regarding the operative, pathological and oncologic results. Focusing on urinary and sexual function, no score values were significantly different at any time between the two groups. The daily frequency of defecation 1 year after surgery was 1.9±0.9 for RISR-TME and 1.8±0.3 for RDS-TME indicating no difference between the two groups. Moreover, there were no significant differences between the two groups in other defecation functions. The mean Wexner score 1 year after surgery was 3.0±1.1 in R-ISR-TME and 2.2±1.0 in R-DS-TME group (p=0.2) and defecation-related quality of life for R-ISR-TME and R-DS-TME was not significantly different (modified fecal incontinence quality of life score: 30.3±19.1 vs 27.5±14.5, respectively; p=0.2). Conclusions: These clinical and functional results suggest that R-ISR-TME could be a good sphincter-preserving surgery for patients with very low rectal cancer. Robotic assistance may overcome some intrinsic limitations of the ISR technique flattening the difference with the DS-TME procedure

    Sexual and urinary dysfunctions are complications in radical treatment of deep infiltrating endometriosis (DIE) with colorectal involvement. The aim of this article is to report the preliminary results of our single-institution experience with robotic treatment of DIE, evaluating intraoperative and postoperative surgical outcomes and focusing on the impact of this surgical approach on autonomic functions such as urogenital preservation and sexual well-being. METHODS: From January 2011 through December 2013, a case series of 10 patients underwent robotic radical treatment of DIE with colorectal resection using the da Vinci System. Surgical data were evaluated, together with perioperative urinary and sexual function as assessed by means of self-administered validated questionnaires. RESULTS: None of the patients reported significant postoperative complications. Questionnaires concerning sexual well-being, urinary function, and impact of symptoms on quality of life demonstrated a slight worsening of all parameters 1 month after surgery, while data were comparable to the preoperative period 1 year after surgery. Dyspareunia was the only exception, as it was significantly improved 12 months after surgery. CONCLUSIONS: Robot-assisted surgery seems to be advantageous in highly complicated procedures where extensive dissection and proper anatomy re-establishment is required, as in DIE with colorectal involvement. Our preliminary results show that robot-assisted surgery could be associated with a low risk of complications and provide good preservation of urinary function and sexual well-being

    open16noIntestinal fibrosis is a complication of inflammatory bowel disease [IBD]. Although fibrostenosis is a rare event in ulcerative colitis [UC], there is evidence that a fibrotic rearrangement of the colon occurs in the later stages. This is a retrospective study aimed at examining the histopathological features of the colonic wall in both short-lasting [SL] and long-lasting [LL] UC. Surgical samples of left colon from non-stenotic SL [a parts per thousand currency sign 3 years, n = 9] and LL [a parts per thousand yen 10 years, n = 10] UC patients with active disease were compared with control colonic tissues from cancer patients without UC [n = 12] to assess: collagen and elastic fibres by histochemistry; vascular networks [CD31/CD105/nestin] by immunofluorescence; parameters of fibrosis [types I and III collagen, fibronectin, RhoA, alpha-smooth muscle actin [alpha-SMA], desmin, vimentin], and proliferation [proliferating nuclear antigen [PCNA]] by western blot and/or immunolabelling. Colonic tissue from both SL-UC and LL-UC showed tunica muscularis thickening and transmural activated neovessels [displaying both proliferating CD105-positive endothelial cells and activated nestin-positive pericytes], as compared with controls. In LL-UC, the increased collagen deposition was associated with an up-regulation of tissue fibrotic markers [collagen I and III, fibronectin, vimentin, RhoA], an enhancement of proliferation [PCNA] and, along with a loss of elastic fibres, a rearrangement of the tunica muscularis towards a fibrotic phenotype. A significant transmural fibrotic thickening occurs in colonic tissue from LL-UC, together with a cellular fibrotic switch in the tunica muscularis. A full-thickness angiogenesis is also evident in both SL- and LL-UC with active disease, as compared with controls.openIppolito, Chiara; Colucci, Rocchina; Segnani, Cristina; Errede, Mariella; Girolamo, Francesco; Virgintino, Daniela; Dolfi, Amelio; Tirotta, Erika; Buccianti, Piero; Di Candio, Giulio; Campani, Daniela; Castagna, Maura; Bassotti, Gabrio; Villanacci, Vincenzo; Blandizzi, Corrado; Bernardini, NunziaIppolito, Chiara; Colucci, ROCCHINA LUCIA; Segnani, Cristina; Errede, Mariella; Girolamo, Francesco; Virgintino, Daniela; Dolfi, Amelio; Tirotta, Erika; Buccianti, Piero; Di Candio, Giulio; Campani, Daniela; Castagna, Maura; Bassotti, Gabrio; Villanacci, Vincenzo; Blandizzi, Corrado; Bernardini, Nunzi

    Sexual and urinary functions after robot-assisted versus pure laparoscopic total mesorectal excision for rectal cancer

    Background Laparoscopic total mesorectal excision (LapTME) is a validated technique for the treatment of rectal cancer. However, the ergonomic limitations of pure laparoscopy could lead to high conversion rates and a high rate of autonomic disorders. For these reasons the robot-assisted TME (RobTME) has been proposed to overcome the limitations of LapTME. The aim of this study is to compare surgical outcomes, medium-term oncologic results, and postoperative autonomic function of LapTME versus RobTME, in a single surgeon experience. Patients and Methods The first 26 LapTME were compared with the first 26 RobTME performed by a single surgeon between January 2009 and May 2013. Perioperative outcomes were prospectively collected and compared. The impact of minimally invasive TME on autonomic function and quality of life (QOL) was analyzed with the ICIQ-FLUTS and the ICIQ-MLUTS (International Consultation on Incontinence–Male/Female Lower Urinary Tract Symptoms) and IIEF (International Index of Erectile Function)/FSFI (Female Sexual Function Index) questionnaires. Pathological aspects and oncological outcomes were also collected. Results Of the 26 LapTME, 22 were anterior resections (ARR), 2 intersphincteric resections (ISR), and 2 abdominoperineal resections (APR), while of the 26 RobTME, 17 were ARR, 5 ISR, and 4 APR. Mean operative time was significantly higher (p<0.001) while conversion rate to hand-assisted or open surgery was significantly lower in the robTME group (p<0.05). There were no significant differences in sexual and urinary scores between the two groups before surgery and at 1 year after surgery. There were no differences in 3 year overall survival, disease free survival, and recurrence rate as well as the other parameters analysed. Conclusion RobTME is a safe and effective technique and the results compare favourably to the results obtained with laparoscopic procedures. It seems a promising alternative to preserve autonomic function and results in a low conversion rate even when used for more high risk procedures such as ISR or APR

    Hand-assisted hybrid laparoscopic–robotic total proctocolectomy with ileal pouch–anal anastomosis

    Get PDF
    PURPOSE: Few studies have reported minimally invasive total proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) and familial adenomatous polyposis (FAP). We herein report a novel hand-assisted hybrid laparoscopic-robotic technique for patients with FAP and UC. METHODS: Between February 2010 and March 2014, six patients underwent hand-assisted hybrid laparoscopic-robotic total proctocolectomy with IPAA. The abdominal colectomy was performed laparoscopically with hand assistance through a transverse suprapubic incision, also used to fashion the ileal pouch. The proctectomy was carried out with the da Vinci Surgical System. The IPAA was hand-sewn through a trans-anal approach. The procedure was complemented by a temporary diverting loop ileostomy. RESULTS: The mean hand-assisted laparoscopic surgery (HALS) time was 154.6 (±12.8) min whereas the mean robotic time was 93.6 (±8.1) min. In all cases, a nerve-sparing proctectomy was performed, and no conversion to traditional laparotomy was required. The mean postoperative hospital stay was 13.2 (±7.4) days. No anastomotic leakage was observed. To date, no autonomic neurological disorders have been observed with a mean of 5.8 (±1.3) bowel movements per day. CONCLUSIONS: The hand-assisted hybrid laparoscopic-robotic approach to total proctocolectomy with IPAA has not been previously described. Our report shows the feasibility of this hybrid approach, which surpasses most of the limitations of pure laparoscopic and robotic techniques. Further experience is necessary to refine the technique and fully assess its potential advantages

    Pancreatoduodenectomy without vascular resection in patients with primary resectable adenocarcinoma and unilateral venous contact:A matched case study

    Purpose. To investigate the oncological outcome and survival of patients following a conservative approach on the portal- mesenteric axis, in an intraoperative ultrasound-selected group of pancreatoduodenectomy (PD), performed on patients with primary resectable with vascular contact (prVC) pancreatic ductal adenocarcinoma (PDAC). Methods. A consecutive series of patients who underwent PD for PDAC at our tertiary care center, between 2008 and 2017, were reviewed. A total of 156 PDs and 88 total pancreatectomies were performed during the study period, including 35 vascular resections. We identified a group of 40 (25.6%) patients with prVC-PDAC in whom after checking the feasibility with intraoperative ultrasound, we were able to perform PD by separation of the tumor from the portomesenteric axis avoiding vascular resection, without residual macroscopic disease (no vascular resection, nvrPD), and compared this group, using case-matched methodology, with the standard PD (sPD) group of primary resectable without vascular contact- (prwVC-) PDAC. Results. The median follow-up was 28.5 ± 23.2 months in the sPD group and 23.8 ± 20.8 months in the nvrPD group (p = 0 35). Isolated local recurrence rate was 2/40 (5%) in both groups. Additionally, there were no statistical differences in the systemic progression of the disease (42.5% sPD vs. 45% nvrPD, p = 0 82) or local plus synchronous systemic disease rates (2.5% sPD vs. 7.5% nvrPD, p = 0 30). The median survival was 22 months for the sPD group and 23 months for the nvrPD group, p = 0 86. The overall survival was similar in the two groups (1 y: 76.3% sPD vs. 70.0% nvrPD; 3 y: 35.6% vs. 31.6%; and 5 y: 28.5% vs. 25.3%; p = 0 80). Conclusions. PD without vascular resection can be considered safe and oncologically acceptable in selected patients with preoperative diagnosis of prVC-PDAC. The poor prognosis of PDAC is related to the aggressive biology and systemic spread of the tumor, rather than the local control of the disease
