Emergency admissions for complicated colonic diverticulitis are increasing: a nationwide register-based cohort study.

BACKGROUND: Acute colonic diverticulitis is common in the Western world representing a growing burden on health care. We aimed to report the factual epidemiological and demographic characteristics in patients with acute diverticulitis in a large nationwide population. METHOD: We conducted a population-based cohort study from 2000 to 2012 on the complete Danish population, which included all patients with acute colonic diverticulitis. Data were composed through two national longitudinal registries. The study main outcomes were demographic development regarding hospital admission, age, gender, geographical residency, and seasonal information. RESULTS: A total of 101,963 acute hospital contacts were identified from 2000 to 2012, of these 44,160 were due to acute diverticulitis. From 2000 to 2012, overall admission rates for complicated diverticulitis increased significantly with 42.7%. There was a small increase in hospital admissions due to acute diverticulitis, and uncomplicated diverticulitis accounted for 83-88% of all admissions. No significant development was seen in cases of uncomplicated diverticulitis. The majority of patients were older than 50 years (85%) and 60% were women. The male gender dominated in patients younger than 50 years (58%), whereas women dominated above 50 years (63%). Mean age and dominating age group decreased significantly from 2000 to 2012 for both genders. A significantly larger proportion of male patients had complicated diverticulitis than uncomplicated diverticulitis. Most admissions were seen during autumn. CONCLUSION: We found that acute colonic diverticulitis has been progressing over the last decade with more severe cases of disease. Our findings underline the need for further research to identify the relevant risk factors and causal circumstances.

Sexual dysfunction after inguinal hernia repair with the Onstep versus Lichtenstein technique: A randomized clinical trial.

BACKGROUND: Sequelae after inguinal hernia repair include pain-related impairment of sexual function. Pain during intercourse can originate from the scar, scrotum, penis, or during ejaculation. The aim of this study was to investigate if the Onstep technique resulted in better results than the Lichtenstein technique regarding pain-related impairment of sexual function. METHODS: This study was part of the randomized ONLI trial (NCT01753219, Onstep versus Lichtenstein for inguinal hernia repair). Separate reporting of pain-related impairment of sexual function was planned before the study start, with a separate sample size calculation. Participants were randomized to the Onstep or Lichtenstein technique for repair of their primary inguinal hernia and followed up at 6 months postoperative with the use of a questionnaire specific for pain-related impairment of sexual function. RESULTS: A total of 259 patients completed the 6-month follow-up, 129 in the Lichtenstein group and 130 in the Onstep group. Among the patients operated with the Onstep technique, 17 experienced pain during sexual activity 6 months after operation compared with 30 patients operated with the Lichtenstein technique (P = .034). Both subgroups that experienced pain during sexual activity had a median visual analog scale score of 0 with an interquartile range of 0 to 2 (P = .349). The Lichtenstein technique resulted in new pain in 14 patients, whereas the Onstep procedure gave new pain in 7 patients (P = .073). CONCLUSION: The Onstep technique was superior to the Lichtenstein technique in terms of pain during sexual activity 6 months after operation.

Risk factors for recurrence after acute colonic diverticulitis: a systematic review.

PURPOSE: Several factors may influence the risk of recurrence after an episode of acute colonic diverticulitis. Until now, a comprehensive systematic overview and evaluation of relevant risk factors have not been presented. This review aimed at assembling and evaluating current evidence on risk factors for recurrence after conservatively treated acute colonic diverticulitis. METHODS: PubMed, Embase, and Cochrane databases were searched for studies evaluating risk factors for recurrence after acute diverticulitis treated non-surgically defined as antibiotic treatment, percutaneous abscess drainage, or by observation. Randomized clinical trials and observational studies were included. Analyzed outcome variables were extracted and grouped. No meta-analysis was performed due to low inter-study comparability. Variables were rated according to their likelihood of causing recurrence (no/low, medium, high). RESULTS: Of 1153 screened records, 35 studies were included, enrolling 396,676 patients with acute diverticulitis. A total of 50,555 patients experienced recurrences. Primary diverticulitis with abscess formation and young age increased the risk of recurrence. Readmission risk was higher within the first year after remission. In addition, the risk of subsequent diverticulitis more than doubled after two earlier episodes of diverticulitis and the risk increased further for every episode. CONCLUSIONS: The best treatment strategy for recurrent diverticulitis is undetermined. However, the risk of a new recurrence seemed to increase after each recurrence making elective resection a viable option at some point after multiple recurrences depending on patient risk factors and preferences.

Chronic pain after inguinal hernia repair with the ONSTEP versus the Lichtenstein technique, results of a double-blinded multicenter randomized clinical trial.

PURPOSE: The open new simplified totally extraperitoneal (ONSTEP) technique for the repair of inguinal hernia was presented some years ago with promising initial results regarding chronic pain. We conducted a randomized clinical trial investigating the ONSTEP technique versus the Lichtenstein technique with focus on postoperative pain. The aim of this paper was to report the results regarding chronic pain from follow-up at 6 and 12 months for the participants in the ONSTEP versus Lichtenstein trial. METHODS: This study was conducted as a randomized double-blinded clinical trial in male participants with primary unilateral hernias, having surgical repair of their hernia at one of five participating general surgical departments. At surgery, participants were allocated (1:1) to the ONSTEP or the Lichtenstein technique for inguinal hernia repair. Participants were followed up with questionnaires at 6 and 12 months. The primary outcome was the proportion of patients with substantial pain-related impairment of daily functions at 6- and 12-month follow-ups. RESULTS: From April 2013 to May 2014, 290 male patients were included in the study. Regarding follow-up for pain, a total of 259 patients (89%) completed the 6-month follow-up and a total of 236 patients (81%) completed the 12-month follow-up. Regarding pain at the 6- and 12-month follow-ups, no difference was found between groups. Two patients operated with Lichtenstein technique developed severe disabling chronic pain postoperatively, which was not seen in the ONSTEP group. CONCLUSION: The ONSTEP technique was not superior to the Lichtenstein technique regarding chronic pain following repair of primary inguinal hernias in males.

[Treatment of acute purulent diverticulitis is still not clarified]. / Valg af behandling af akut, purulent divertikulitis er uafklaret.

Inflammation in colonic diverticula can develop into acute diverticulitis. Treatment varies depending on illness severity. Perforated diverticulitis with faecal peritonitis is treated surgically and Hartmann's procedure is the preferred operation. Peritoneal lavage might be an alternative to resection for purulent peritonitis. However, ongoing randomized trials are awaited to clarify this.

[Antibiotic treatment as the standard for appendicitis].

Acute appendicitis has traditionally been treated surgically. Conservative approach with antibiotic treatment has been suggested as an alternative to the surgical procedure. The available studies on surgery versus antibiotics may indicate the safe use of conservative treatment for uncomplicated appendicitis, but the available studies are typically of low quality. Thus, further studies are needed to clarify the role of conservative treatment, and in the meantime appendectomy remains the standard treatment for acute appendicitis.

[Challenging investigation of a metastatic adnexal cutaneous tumour].

Adnexal cutaneous tumours are very rare. A lack of knowledge about their clinical presentations can lead to prolonged diagnostic investigations and disease progression. This case report presents a challenging investigation of a metastatic malignant adnexal tumour due to misleading histology, immunohistochemical analysis and clinical findings.

The best choice of treatment for acute colonic diverticulitis with purulent peritonitis is uncertain.

Severe stages of acute, colonic diverticulitis can progress into intestinal perforations with peritonitis. In such cases, urgent treatment is needed, and Hartmann's procedure is the standard treatment for cases with fecal peritonitis. Peritoneal lavage may be an alternative to resection for acute diverticulitis with purulent peritonitis, but ongoing randomized trials are awaited to clarify this.
