The gastroenterologist's view

Recurrences and Ongoing Complaints of Diverticulitis; Results of a Survey among Gastroenterologists and Surgeons

OBJECTIVE

This study aims to investigate the current opinion of gastroenterologists and surgeons on treatment strategies for patients, with recurrences or ongoing complaints of diverticulitis.

BACKGROUND

Treatment of recurrences and ongoing complaints remains a point of debate. No randomized trials have been published yet and guidelines are not uniform in their advice.

DESIGN

A web-based survey was conducted among gastroenterologists and GE-surgeons. Questions were aimed at the treatment options for recurrent diverticulitis and ongoing complaints.

RESULTS

In total, 123 surveys were filled out. The number of patients with recurrent or ongoing diverticulitis who were seen at the outpatient clinic each year was 7 (0-30) and 5 (0-115) respectively. Surgeons see significantly more patients on an annual basis 20 vs. 15% (p = 0.00). Both surgeons and gastroenterologists preferred to treat patients in a conservative manner using pain medication and lifestyle advise (64.4 vs. 54.0, p = 0.27); however, gastroenterologists would treat patients with mesalazine medication, which is significantly more (28%, p = 0.04) than in the surgical group. Surgeons are inclined more towards surgery (31.5%, p = 0.02).

CONCLUSIONS

Both surgeons and gastroenterologists prefer to treat recurrent diverticulitis and ongoing complaints in a conservative manner. Quality of life, the risk of complications and the viewpoint of the patient are considered important factors in the decision to resect the affected colon.

The relation between quality of life and histopathology in diverticulitis; can we predict specimen-related outcome?

PURPOSE

An important factor in the decision to perform laparoscopic sigmoid resection for patient suffering from recurrent and ongoing diverticulitis is quality of life (QoL). It is unknown whether quality of life relates to the severity of diverticulitis as seen in the resected colonic segment. The aim of this study is to analyze histopathological findings of patients suffering from recurrent or ongoing diverticulitis and their QoL before and after surgery in order to improve patient outcome prediction.

METHODS

A cohort of consecutive patients with diverticulitis between January 2010 and April 2014 was analyzed. All patients were scheduled for surgery and had at least three episodes of diverticulitis or more within the last 2 years or experienced ongoing complaints for at least 3 months or more and confirmation by a radiologist. We compared QoL questionnaires, to known histopathological entities.

RESULTS

For this study, 54 consecutive patients were included, 15 (27.8%) men and 39 (72.2%) women. A marked difference in quality of life before and after surgery for patients having a more severe histopathological entity was not found (p = 0.83). However, a clinically relevant higher VAS score 6 months after surgery was shown in patients with peritonitis. Furthermore, these patients had more fibrosis in the histopathological samples.

CONCLUSION

In conclusion, even though a relation between the different pathological entities and QoL could not be determined, patients with diverticulitis and concomitant microscopic peritonitis had significantly more fibrosis and suffered from a higher VAS scores 6 months after surgery.

[Diverticular disease - diagnosis and classification]

A reliable diagnosis is fundamental for operative, interventional and conservative treatment of the different facets of diverticular disease. Not only differential diagnoses but also overlap or coincidence with other entities sharing similar symptoms must be considered. Furthermore, an adequate surgical strategy and correct stratification of complications is mandatory. Subsequently, in the light of currently validated diagnostic techniques, the consensus conference of the German Societies of Gastroenterology (DGVS) and Visceral Surgery (DGAV) has released a new classification of diverticulitis displaying the different facets of diverticular disease. This classification also comprises symptomatic uncomplicated diverticular disease (SUDD), largely resembling irritable bowel syndrome, as well as diverticular bleeding. While detailed history, physical examination and laboratory testing are of great importance for exploring a patient with diverticular disease, they are not sufficient to diagnose (or stratify) diverticulitis without cross-sectional imaging using ultrasonography (US) or computed tomography (CT). The diagnostic value of qualified US is equipotent to qualified CT, complies with relevant legislation for radiation exposure protection and is frequently effective for diagnosis. Therefore, US is considered to be the first choice for imaging in diverticular disease. In contrast, CT has definite indications in unclear, discrepant situations or insufficient US performance. Strengths and weaknesses of both methods are discussed. Endoscopy is not required for the diagnosis of diverticulitis and should not be performed in an acute attack. Colonoscopy, however, is warranted after healing of diverticulitis, prior to elective surgery and in cases of an atypical course. Prior exclusion of perforation is considered mandatory. An unequivocal indication for colonoscopy is diverticular bleeding and the rapid performance (within 12-24 h) allows better identification of sites of bleeding and endoscopic interventions.
