    Symptomatic Uncomplicated Diverticular Disease (SUDD): Practical Guidance and Challenges for Clinical Management

    Get PDF
    Symptomatic Uncomplicated Diverticular Disease (SUDD) is a syndrome within the diverticular disease spectrum, characterized by local abdominal pain with bowel movement changes but without systemic inflammation. This narrative review reports current knowledge, delivers practical guidance, and reveals challenges for the clinical management of SUDD. A broad and common consensus on the definition of SUDD is still needed. However, it is mainly considered a chronic condition that impairs quality of life (QoL) and is characterized by persistent left lower quadrant abdominal pain with bowel movement changes (eg, diarrhea) and low-grade inflammation (eg, elevated calprotectin) but without systemic inflammation. Age, genetic predisposition, obesity, physical inactivity, low-fiber diet, and smoking are considered risk factors. The pathogenesis of SUDD is not entirely clarified. It seems to result from an interaction between fecal microbiota alterations, neuro-immune enteric interactions, and muscular system dysfunction associated with a low-grade and local inflammatory state. At diagnosis, it is essential to assess baseline clinical and Quality of Life (QoL) scores to evaluate treatment efficacy and, ideally, to enroll patients in cohort studies, clinical trials, or registries. SUDD treatments aim to improve symptoms and QoL, prevent recurrence, and avoid disease progression and complications. An overall healthy lifestyle – physical activity and a high-fiber diet, with a focus on whole grains, fruits, and vegetables – is encouraged. Probiotics could effectively reduce symptoms in patients with SUDD, but their utility is missing adequate evidence. Using Rifaximin plus fiber and Mesalazine offers potential in controlling symptoms in patients with SUDD and might prevent acute diverticulitis. Surgery could be considered in patients with medical treatment failure and persistently impaired QoL. Still, studies with well-defined diagnostic criteria for SUDD that evaluate the safety, QoL, effectiveness, and cost-effectiveness of these interventions using standard scores and comparable outcomes are needed

    International audienceBackground: Although minimally invasive rectal surgery (MIRS) for cancer provides better recovery for similar oncologic outcomes over open approach, conversion is still required in 10% and its impact on short-term and long-term outcomes remains unclear. The aim of our study was to evaluate the impact of conversion on postoperative and oncologic outcomes in patients undergoing MIRS for cancer. Methods: From June 2011 to March 2020, we reviewed 257 minimally invasive rectal resections for cancer recorded in a prospectively maintained database, with 192 robotic and 65 laparoscopic approaches. Patients who required conversion to open (Conversion group) were compared to those who did not have conversion (No conversion group) in terms of short-term, histologic, and oncologic outcomes. Univariate and multivariate analyses of the risk factors for postoperative morbidity were performed. Results: Eighteen patients (7%) required conversion. The conversion rate was significantly higher in the laparoscopic approach than in the robotic approach (16.9% vs 3.6%, p < 0.01). Among the 4 reactive conversions, 3 (75%) were required during robotic resections. Patients in the Conversion group had a higher morbidity rate (83.3% vs 43.1%, p = 0.01) and more severe complications (38.9%, vs 18.8%, p = 0.041). Male sex [HR = 2.46, 95%CI (1.41–4.26)], total mesorectal excision [HR = 2.89, 95%CI (1.57–5.320)], and conversion (HR = 4.87, 95%CI [1.34–17.73]) were independently associated with a higher risk of overall 30-day morbidity. R1 resections were more frequent in the Conversion group (22.2% vs 5.4%, p = 0.023) without differences in the overall (82.7 ± 7.0 months vs 79.4 ± 3.3 months, p = 0.448) and disease-free survivals (49.0 ± 8.6 months vs 70.2 ± 4.1 months, p = 0.362). Conclusion: Conversion to laparotomy during MIRS for cancer was associated with poorer postoperative results without impairing oncologic outcomes. The high frequency of reactive conversion due to intraoperative complications in robotic resections confirmed that MIRS for cancer is a technically challenging procedure

    Aim: The use of robotic-assisted laparoscopy seems fully adapted to pelvic surgery. However, few studies focus on robotic-assisted abdominoperineal resection (RAAPR). The aim of this study was to assess the feasibility, short-term postoperative outcomes, and pathological results of RAAPR. In addition, we provide a detailed description of the operative procedure and a brief review of the current literature.Methods: Between January 2013 and April 2018, we performed a total of 428 robotic surgeries, including 294 colorectal resections (68.7%). Data were prospectively collected and included demographics, intraoperative findings, postoperative outcomes, and pathological data. For this study, we included the first 20 consecutive RAAPRs performed with the four-arm da Vinci Si surgical system (Intuitive Surgical Inc., Sunnyvale, CA, USA).Results: Twenty patients (nine men) with a mean age of 68 years and a mean BMI of 24.5 ± 5.0 kg/m2 underwent RAAPR for low rectal adenocarcinoma (80%) or squamous cell carcinoma of the anal canal. Sixteen (80%) patients underwent preoperative pelvic radiotherapy and eight (40%) had a history of previous abdominal surgery. Mean operative duration was 218 ± 52 min. There was no conversion to open surgery. Mortality, reoperation, and morbidity rate were 5%, 25%, and 60%, respectively. Three (15%) patients presented perineal complications. Mean length of hospital stay was 20 days. Three (15%) patients had pT4 tumor. Mesorectal excision was considered complete in 90%. On average, 16.5 ± 7.2 lymph nodes were retrieved.Conclusion: RAAPR is feasible, with acceptable pathologic and short-term outcomes. The current literature does not demonstrate significant differences between robotic and laparoscopic APR. Indeed, we cannot justify its use in routine on the basis on the available evidence

    This is a systematic review and meta-analysis on the surgical treatments of splenic flexure carcinomas (SFCs). Medline, EMBASE, and Scopus were searched from January 1990 to May 2016. Studies of at least 5 patients comparing extended right colectomy (ERC) versus left colectomy (LC) and/or laparoscopy versus open surgery for SFCs were retrieved and analyzed. Overall, 12 retrospective studies were selected, including 569 patients. ERC was performed in 23.2% of patients, whereas LC in 76.8%. Pooled data suggested that ERC and LC had similar oncologic quality of resection and postoperative outcomes. Laparoscopy was used in 50.6% of patients (conversion rate: 2.5%) and it was associated with significantly shorter time to oral diet, fewer postoperative complications, and shorter hospital stay than open surgery. In conclusion, the optimal extent of SFC surgical resection, that is, ERC or LC remains under debate. However, laparoscopy provides better postoperative outcomes and fewer postoperative complications than open surgery

    Background. Optimal modalities for diagnosis, treatment, and surveillance of portal or splenic vein thrombosis have not yet been defined. The present retrospective study aimed to investigate the role of computed tomography performed systematically before and after laparoscopic splenectomy to assess the incidence of portal or splenic vein thrombosis, predictors, and outcomes. Methods. Computed tomography scans were obtained from 170 patients undergoing elective laparoscopic splenectomy between 2005 and 2015. Pre- and postoperative splenic vein diameter was measured at the splenoportal junction and at a distance of 2, 4, 6 cm from it. Univariate and multivariate analyses were used to identify portal or splenic vein thrombosis risk factors and predictors of treatment outcome. Results. Overall, 68.2% of patients had benign hematologic diseases; 64.1% showed splenomegaly. Portal or splenic vein thrombosis occurred in 53.5% of patients (91/170), of whom 49.5% were asymptomatic. Preoperative splenic vein diameter measurements at 2, 4, and 6 cm from the splenoportal junction were significantly greater in portal or splenic vein thrombosis patients than in no-portal or splenic vein thrombosis patients. Patients with splenic vein diameter $8 mm at all measured sites had a greater risk of developing portal or splenic vein thrombosis (P = .009; odds ratio, 2.57; 95% confidence interval, 1.26–5.23). The majority of thromboses involved the distal splenic vein (45.1%, 41/91), and 41.7% of patients had thromboses located in multiple sites. Fully 71.4% showed complete resolution of portal or splenic vein thrombosis. Thrombus location at a single site predicted a favorable treatment outcome (P &lt; .0001). Conclusion. Portal or splenic vein thrombosis is a frequent complication of splenectomy that occurs asymptomatically in half of cases. Computed tomography could have an important role in identifying patients at risk of developing portal or splenic vein thrombosis as well as in predicting portal or splenic vein thrombosis resolution.
