Laparoscopic intracorporeal double purse-string ileorectal anastomosis with transanal natural orifice specimen extraction
No full textTransanal natural orifice specimen extraction (t-NOSE) has the potential benefit to minimize risks of surgical site infection and incisional hernia at the extraction site. We describe how t-NOSE can be used to deliver an intact specimen after laparoscopic total colectomy with oncologic criteria and, at the same time,
to ease a double pursestring, single-stapled intracorporeal ileorectal anastomosis

Full text linkReduced duration of stay after elective colorectal surgery during the peak phase of COVID-19 pandemic: A positive effect of infection risk awareness?
No full textBackground: While elective surgery was shut down in most settings during the 2019 novel coronavirus
pandemic, some referral centers were designated as surgery hubs. We sought to investigate how the
pandemic scenario impacted the quality of a long-established enhanced recovery protocol colorectal
surgery program in 2 referral centers, designated as colorectal surgery hubs, located in the epicentral
Italian regions hardest hit by the pandemic.
Methods: We compared short-term outcomes of patients undergoing major colorectal surgery with a
long-established enhanced recovery protocol during the coronavirus disease 2019 outbreak occurred in
2020 (group A) with the correspondent timeframe of 2019 (group B). Primary outcomes were morbidity
and mortality, duration of stay, and readmission rate.
Results: One hundred and thirty-six patients underwent major colorectal surgery in group A and 173 in
group B. Postoperative complications and readmission rate were comparable between the 2 groups.
Oncologic case-log was predominant in group A compared with group B (73.5 vs 61%; P 1⁄4 .01). A
significantly shorter overall duration of stay was found in group A (P < .001). Uncomplicated patients of
group A had a shorter duration of stay when compared with uncomplicated patients of group B (P 1⁄4
.008).
Conclusion: Under special precautionary measures, major colorectal surgery can be undertaken on
elective basis even during coronavirus disease 2019 pandemic with reasonable results. A reduction of
duration of stay within a long-established enhanced recovery protocol colorectal surgery program was
observed during the coronavirus disease 2019 pandemic occurred in 2020 in comparison with the
correspondent timeframe of the previous year without compromising short-term outcomes. The
pandemic uncovered the positive impact of patients’ commitment to reducing duration of stay as the
empowered risk awareness likely promoted their compliance to the enhanced recovery protoco
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Immediate versus early (24-hours) urinary catheter removal after elective minimally invasive colonic resection: study protocol for a randomized, multicenter, non-inferiority trial
Full text linkEnhanced Recovery After Surgery (ERAS) represents the standard of care in colorectal surgery. Among ERAS items, early removal of urinary catheter (UC) is considered a key issue, though adherence to this specific item still varies among centers. UC placement allows for monitoring of post-operative urinary output but relates to an increased risk of urinary tract infection (UTI), reduced mobility, and patient's discomfort. Several studies investigated the role of early UC removal specifically looking at the rate of acute urinary retention (AUR) but most of them were retrospective, single-center, underpowered, cohort studies. The main purpose of this study is to compare the rate of AUR after immediate (at the end of the surgery) versus early (within 24 h from the completion of surgery) removal of UC in patients undergoing minimally invasive colonic resection (MICR). The secondary outcomes focus on goals that could be positively impacted by the immediate removal of the UC at the end of the surgery. In particular, the rate of UTIs, perception of pain, time-to-return of bowel and physical functions, postoperative complications, and length of hospital stay will be measured
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
The Impact of Crohn’s Perianal Fistula on Quality of Life: Results of an International Patient Survey
Full text linkLay Summary Results from an online survey completed by patients with Crohn's disease (CD) and perianal fistulas showed the presence of perianal fistulae has a greater negative impact as compared to CD-only patients. These results may help practitioners address patient burden.Background Crohn's perianal fistula is a disabling manifestation of Crohn's disease. However, the additional burden of perianal fistula on patients with only Crohn's disease remains to be addressed. This patient-reported survey considered outcomes of two domains: "diagnosis" (eg, symptoms) and "living with the disease" (eg, quality of life, well-being, and relationships). Methods Patients with perianal fistula and Crohn's disease completed an online, self-selective, anonymous, 46-item survey available in 11 languages hosted on the European Federation of Crohn's & Ulcerative Colitis Associations and national patient association websites. The survey was conducted between July and December 2019 in Europe and other regions. Likert scales and closed questions were used to assess outcomes. Results Of the 820 respondents with Crohn's disease (67.2% women; median age, 40.0 years), 532 (64.9%) reported the presence of perianal fistula. Patients with perianal fistula reported a greater impact on overall quality of life (P < .001), well-being (P < .001), relationships (P < .001), social life (P = .001), and work life (P = .012) than patients with only Crohn's disease. Conclusions Perianal fistulas impact several domains of the life of patients with Crohn's disease. These results may help healthcare practitioners plan therapeutic strategies that address the symptomatic and psychological burden experienced by patients with perianal fistulizing Crohn's disease
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
