Trends in emergent diverticular disease management: a nationwide cohort study from 2009 to 2018.

BACKGROUND: Diverticular disease is a common disorder. Several guidelines report on its optimal management. The aim of this study was to describe the evolution of the prevalence of this disease, the treatment strategies, and the mortality rate on a national level. METHODS: We conducted a retrospective study on prospective data using a nationwide database. All consecutive adult patients diagnosed with diverticular disease and admitted via the emergency department from 2009 to 2018 were included in the study. We performed a descriptive analysis for epidemiologic data, diagnosis, and treatment. RESULTS: During the data collection period, 233,386 patients were included in the study. The number of admissions for emergent diverticular disease increased by 65.8%, from 16,754 in 2009 to 27,781 in 2018, for both uncomplicated and complicated diverticular disease. Among these patients, 19,350 (8.3%) were operated on. The rate of surgical treatment progressively decreased from 9.7% in 2009 to 7.6% in 2018. The three main interventions were Hartmann's procedure (HP, n = 9111, 47.1%), resection with primary anastomosis (RPA, n = 4335, 22.4%), and peritoneal lavage (PL, n = 4836, 25%). We observed a progressive annual increase in HPs (n = 716 in 2009 and n = 1055 in 2018) as well as a decline in PLs since 2015, while the number of RPAs remained stable. CONCLUSIONS: Although admissions for emergent diverticular disease have increased during the study period, the rate of surgical treatment has decreased, suggesting an evolution toward more conservative management of this pathology.

High-grade poorly differentiated retroperitoneal sarcoma. Report of a case and review of the literature.

Retroperitoneal sarcomas (RPS) are uncommon tumors associated with a poor prognosis. This is particularly true in case of high-grade sarcomas of specific histological subtypes, as demonstrated by the largest surveys of the last decade. Up to the present day, unfortunately there are no powerful tools available except for surgery. On the other hand, the resection rate of RPS is significantly increased over the last decades allowing to deliver the best treatment available. This paper reports on the case of a young patient who was incidentally diagnosed with a retroperitoneal mass. The patient underwent surgery in our department and the histological report showed a spindle cell sarcoma of high grade of malignancy with an incomplete muscular phenotype. The patient was discharged on the seventh postoperative day and he is still free of local and distant recurrence.

Is fixation during gastric banding necessary? A randomised clinical study.

Anterior fixation via a gastro-gastric suture in laparoscopic adjustable gastric banding (LAGB) is commonly performed to prevent band-related complications. However, the necessity of this common technique has never been proven. Not fixing the band would be time sparing and would reduce adhesions on the stomach and probably make revisional surgery easier. This study was conceived as a 3-year randomised clinical trial to test the safety and efficacy of the non-fixation technique. From December 2006 to December 2007, 81 patients undergoing LAGB were randomly distributed into two groups: group A, with gastro-gastric sutures (n = 41) and group B, without gastro-gastric fixation (n = 40). The two groups were equivalent regarding initial body mass index (BMI), age and sex ratio. The main outcome was postoperative complications and secondary outcomes were operative time and weight loss expressed by the percentage of excess BMI loss (%EBMIL). All patients were prospectively followed up for 2 years. The mean preoperative BMI was 42.5 kg/m² (35-56). All patients were available for follow-up at 2 years. The mean overall preoperative time was 82 ± 20 min for the fixation group and 72 ± 20 min for the non-fixation group (p = 0.13). The mean hospital stay was 4.1 ± 1.5 days (no significant difference between the two groups). The 2-year %EBMIL was 35.9 for group A and 39.4 for group B (p = NS). The mean BMI at 2 years was 36.3 and 36.1, respectively, with no statistical difference. We observed three early band slippages in the non-fixation group and none in the fixation group. Three bands were removed during the second year of follow-up for causes other than band slippage (no significant difference between the two groups). This study was interrupted before a statistical significance could be reached, under the general agreement of all participating surgeons, because of the three unexpected early band slippages. For the patients who did not suffer from this complication, we did not observe any differences between the two groups in terms of late complications and weight loss. The operative time was shorter in the non-fixation group. This randomised clinical trial suggests that care should be taken when not fixating the LAGB because of the risk of early postoperative band slippage. We suggest that fixing the LAGB by gastro-gastric sutures should remain common practice.

A self-adhering mesh for inguinal hernia repair: preliminary results of a prospective, multicenter study.

BACKGROUND: Prosthetic reinforcement is the gold standard treatment for inguinal hernia and reduces the risk of recurrence. Yet up to one-third of patients complain of post-surgical pain due to irritation and inflammation caused by the mesh and the fixation materials. Of these patients, 3-4% will experience severe and disabling chronic pain. We performed a prospective multicenter clinical study of a self-adhering prosthesis, consisting of a lightweight polypropylene mesh (40 g/m²) coated on each side with synthetic glue, to evaluate early postoperative complications and patient outcomes. PATIENTS AND METHODS: Between August 2008 and June 2010, 186 patients underwent hernia repair using the Lichtenstein technique and the self-adhering prosthesis. Primary endpoints were the frequency of disabling complications and quality of life (QoL) at 3-month follow-up. Pain, numbness, and groin discomfort were evaluated pre- and postoperatively (1 week, 1 and 3 months) using a visual analogue scale (VAS). Patients' pre- and postoperative QoL were measured using the SF12 questionnaire. Secondary endpoints were number of complications and recurrence rate, use of analgesic drugs, length of hospital stay, delay to return to normal activities, and patient satisfaction. The quality of the self-adhering mesh and its clinical utility were also evaluated by the participating surgeons. RESULTS: A total of 186 patients were enrolled and followed for at least 3 months after inguinal hernia repair. A total of 174 (95%) primary hernias and 12 (5%) recurrent hernias were treated. There were no intraoperative complications, no recurrences, and no repeat interventions performed during the study. The post-surgical complication rate was 4.5%. The mean delay to recover normal physical activity was 4 days. For the primary endpoint of pain, a VAS of zero was reported by 93/184 (50.5%) patients at 1 week, 130/171 (76.0%) patients at 1 month and 119/132 (90.2%) patients at 3 months' follow-up (P < 0.0001). The postoperative SF12 scores showed a significant improvement in patient QoL following surgery (P < 0.0001). CONCLUSIONS: Adhesix( ® ) self-adhering mesh for prosthetic reinforcement following inguinal hernia repair is atraumatic and associated with infrequent post-surgical complications or pain, a rapid recovery rate, and a high patient-reported QoL. A longer follow-up is underway to assess the frequency of post-surgical recurrence.

Geographical Information Systems and on-line GIServices for health data sharing and management.

Integrating Geographical Information Systems (GIS) technology and public health experience may represent a solution for a better comprehension of spatial and temporal trends of phenomena. Useful applications can be built that support practitioners in their daily tasks, from risk assessment to prevention programmes. Also, making available data on the Internet through GIServices represents an important goal. Institutions and public health practitioners may benefit from the technological integration of GIS, the Web, handheld and mobile global positioning systems (GPS) devices. Expert users may be supported in deriving thematic maps which represent a spatial synthesis documentation starting from an analytic study expressed in terms of numbers and features. In this paper we show an example of an on-line data sharing and processing application, emphasizing ways GIS can provide added value to health research and management.
