Purpose The study aimed to evaluate the feasibility and safety of a new trans-anal rectoscopic-assisted minimally invasive surgery (ARAMIS) platform to treat rectal lesions. Methods ARAMIS was first compared with two transanal minimally invasive surgery platforms (SILS Port and GelPOINT Path) on human cadavers. Surgeons with different experience performed running sutures at different distances, at four quadrants, using the three platforms and gave a score to visibility, safety, and maneuverability. ARAMIS was then utilized on patients affected with rectal neoplasia who met the inclusion criteria. Patients and tumor characteristic and results were prospectively collected. The follow-up examinations included proctoscopy at 3, 6, and 12 months. Results According to surgeons’ scores, ARAMIS improves visibility and safety with respect to other platforms for distances beyond 10 cm. The procedure, which lasted an average of 59 min, was successfully carried out in 14 patients. No intraoperative or postoperative complications were reported. The mean tumor size was 3 cm; they were located a mean of 11 cm from the anal verge. Complete removal of the lesion was possible in 13/14 patients. There was one case of adenoma recurrence at follow-up. Conclusion Study results showed that ARAMIS, which is equipped with an adjustable rectoscope, can be considered a safe, effective platform for transanal surgery. The rectoscope protects the rectum during the procedure, a particularly important consideration when proximal rectal lesions are being treated. Further clinical studies are warranted to confirm these encouraging results.

PURPOSE: The study aimed to evaluate the QoL in patients who underwent elective surgery for uncomplicated diverticulitis using a recently developed diverticulitis quality of life questionnaire (DV-QoL). METHODS: All consecutive patients who underwent surgery for uncomplicated diverticulitis or who were hospitalized and treated conservatively for acute uncomplicated diverticulitis episodes in three referral centers, in a 5-year period, were included in the study. The 36-Item Short Form Survey and the DV-QoL were administered to the patients to assess their QoL before and after treatment of diverticular disease. RESULTS: Ninety-seven patients who underwent surgery, 44 patients who were treated conservatively, and 44 healthy volunteers were included in the study. DV-QoL scores correlated with SF-36 scores (p

Aim The aim of this study was to investigate risk factors for anastomotic stenosis in patients operated on for diverticular disease. Histological inflammation and diverticula at the resection margins were also considered. Method Patients' characteristics, the surgical technique and postoperative complications were collected from the medical records. Anastomotic stenoses were evaluated prospectively by rigid sigmoidoscopy during follow-up examination. Histological specimens were examined by a single pathologist who investigated inflammation and diverticula at the resection margins. Twenty patients with anastomotic colorectal stenosis from a single tertiary centre were compared with 24 consecutive patients without stenosis. They were all operated on for diverticular disease over a specified time period. Results Histological inflammation and diverticula were found in 25% and 30% of the resection margins respectively. Univariate analysis showed that age > 71 years (P = 0.0002), female gender (P = 0.0069) and anastomoses located below 12 cm from the anal verge (P = 0.020) were risk factors for stenosis. No correlation was found between anastomotic stenosis and the presence of histological inflammation or diverticula at the resection margins. By multivariate analysis, only age > 71 years was found to be a statistically significant risk factor for stenosis (P = 0.0003, OR = 60.8, 95% CI: 6.4-575.5). Conclusion Anastomotic stenosis is a frequent, long-term complication following surgery for diverticular disease. An analysis demonstrated that age is a risk factor for colorectal stenosis and that histological inflammation and the presence of diverticula near/at the resection margins have no effect on the incidence of stenosis.
