Importance of the Duodenal Window and Fredet's Fascia in Laparoscopic Right Hemicolectomy. Technical Note
No full textBackground: Laparoscopic right hemicolectomy requires a precise anatomical dissection to mobilise the right and proximal transverse mesocolon, following the avascular fusion planes of Toldt and Fredet. Fredet's plane is crucial to the preparation of the origin of vessels. Easy access to Fredet's and Toldt's fasciae can be obtained through the "duodenal window", a flimsy area of the root of the proximal transverse mesocolon, the margins of which are the right border of the superior mesenteric pedicle, the ileocolic pedicle, the right colic pedicle and the marginal artery.
Method: We propose that dissection of the duodenal window should be the first step in laparoscopic right hemicolectomy, to obtain easy access to the duodenopancreatic plane and prepare the fascia.
Results: This "duodenal window-first" technique has been applied in 45 laparoscopic right hemicolectomies and 14 laparoscopic extended right hemicolectomies, with only two conversions to open surgery. The duodenal window was easily identified in all but 3 cases with significant visceral obesity. No significant intra- or postoperative morbidity was recorded in these cases and the median postoperative length of stay was 4 days. All resections were R0 and an adequate number of retrieved lymph nodes were obtained in almost all cases.
Conclusion: The duodenal window-first approach is a feasible and safe technique to standardise the first steps of radical laparoscopic right hemicolectomy, allowing prompt and complete anatomical identification and dissectio
Proposal and Validation of a New Classification of Surgical Outcomes after Colorectal Resections within an Enhanced Recovery Programme
No full textAdvantages of Enhanced Recovery (ER) programmes in colorectal surgery have already been demonstrated, but heterogeneity exists with respect to the choice of compared outcomes. A comprehensive classification aimed at standardizing the reporting of surgical outcomes has been proposed and validated. Method. Clinical variables of 231 patients who underwent colorectal resections within an ER programme from 2013–2018 were analysed. Their outcomes have been reported according to a new classification in 5 classes and 11 subclasses. Prognostic variables have been identified. Results. Seventy-nine patients (34.2%) had an optimal class 1 outcome. Almost half of the patients had an uneventful recovery after being discharged after day 4 (2a). Only two patients (0.9%) were discharged early and then readmitted for a minor ailment (2b). Total morbidity was 12.6% (3a–5). Perioperative mortality was 2.6% (5). Young age, laparoscopic resection, and years of experience with ER have been identified as independent prognostic factors towards a totally positive outcome. Conclusions. The proposed outcome classification is a simple and objective tool to report the surgical outcome in clinical studies. Its implementation seems to be appropriate, in particular, in the field of ER protocols in colorectal surgery, but it can have a wider application in any other surgical subspeciality

Patients were divided in 3 groups on the basis of the emergency treatment they received, namely 1) immediate resection, 2) damage control procedure and elective or semielective resection, and 3) no radical treatment. Demographic variables, clinical data, and treatment data were considered, and formed the basis for the comparison of groups. Primary endpoints were 90-day mortality and morbidity. Secondary endpoints were length of stay, number of lymph nodes analyzed, rate of radical R0 resections, and the number of patients who had chemoradiotherapy.Results: Forty-two patients did not have any radical treatment because the cancer was too advanced or they were too ill to tolerate an operation, 78 patients had immediate resection and 11 had damage control followed by elective resection. There was no statistically significant difference between immediate resections and 2-stage treatment in 90-day mortality and morbidity (mortality: 15.4% vs 0%; morbidity: 26.9% vs 27.3%), number of nodes retrieved (16.6±9.4 vs 14.9±5.7), and rate of R0 resections (84.6% vs 90.9%), but mortality was slightly higher in patients who underwent immediate resection. The patients who underwent staged treatment had a higher possibility of receiving a laparoscopic resection (11.5% vs 36.4%).Conclusion: The present study failed to demonstrate a clear superiority of one treatment with respect to the other, even if there is an interesting trend favoring staged resection.

Laparoscopic appendectomy with single port vs conventional access: systematic review and meta-analysis of randomized clinical trials
No full textBackgroundConventional three-access laparoscopic appendectomy (CLA) is currently the gold standard treatment, however, Single-Port Laparoscopic Appendectomy (SILA) has been proposed as an alternative. The aim of this systematic review/meta-analysis was to evaluate safety and efficacy of SILA compared with conventional approach.MethodsPer PRISMA guidelines, we systematically reviewed randomised controlled trials (RCTs) comparing CLA vs SILA for acute appendicitis. The randomised Mantel-Haenszel method was used for the meta-analysis. Statistical data analysis was performed with the Review Manager software and the risk of bias was assessed with the Cochrane "Risk of Bias" assessment tool.ResultsTwenty-one studies (RCTs) were selected (2646 patients). The operative time was significantly longer in the SILA group (MD = 7,32), confirmed in both paediatric (MD = 9,80), (Q = 1,47) and adult subgroups (MD = 5,92), (Q = 55,85). Overall postoperative morbidity was higher in patients who underwent SILA, but the result was not statistically significant. In SILA group were assessed shorter hospital stays, fewer wound infections and higher conversion rate, but the results were not statistically significant. Meta-analysis was not performed about cosmetics of skin scars and postoperative pain because different scales were used in each study.ConclusionsThis analysis show that SILA, although associated with fewer postoperative wound infection, has a significantly longer operative time. Furthermore, the risk of postoperative general complications is still present. Further studies will be required to analyse outcomes related to postoperative pain and the cosmetics of the surgical scar
Appendicovesical fistula presenting as hypokalaemic hyperchloraemic metabolic acidosis: a case report
No full textRoutine use of open technique in laparoscopic operations
No full textBACKGROUND: The "blind" insertion of the Veress needle for insufflation of the peritoneal cavity with subsequent closed placement of the first trocar during laparoscopic abdominal procedures can result in severe major vascular and visceral injuries. An open technique was proposed as an alternative method for insufflation in patients with abdominal scars to reduce the possibility of such complications. The aim of this article is to report the results of our experience with the routine use of open technique in laparoscopic surgery.
STUDY DESIGN: Open technique was routinely used and prospectively evaluated in 330 patients who underwent laparoscopic procedures.
RESULTS: Laparoscopic conversion was necessary in 25 out of 330 cases (7.6 percent): in 20 cases for unclear biliary anatomy during laparoscopic cholecystectomy, and in 5 cases for minor hemorrhage that could not be managed by laparoscopy. In the 305 procedures completed by laparoscopy, 11 patients (3.6 percent) had 13 postoperative complications. These complications were all of minor importance and were always unrelated to trocar insertion; in particular, no major vascular or visceral injuries were observed.
CONCLUSIONS: Routine use of open technique for pneumoperitoneum represents the best prevention of most of the severe trocar-related complications that are potentially avoidable
