[Recommendations for treatment of diverticular disease]

[Indications for surgical treatment of diverticular disease]

BACKGROUND

The correct medical indications are the fundamental decision process for the surgical treatment and ensuring the quality.

OBJECTIVE

Description of the indications for surgical treatment of the various types of diverticular disease according to the current level of evidence.

MATERIAL AND METHODS

The narrative review is based on current national and international guidelines and a selective literature search.

RESULTS

There are basically three main indications for resection of the sigmoid colon. 1) Prophylactic for avoidance of complications after successful conservative treatment of acute complicated diverticulitis with macroabscess formation and high risk of recurrence (classification of diverticular disease, CDD, type 2b). 2) In patients with persistent symptoms and impaired quality of life resection of the sigmoid colon of various types (CDD types 1-3) can effectively enable a significant improvement in the quality of life and is therefore to be recommended in cases of individually acceptable perioperative risks. 3) Indications for urgent resection of the sigmoid colon are present for free perforation or failure of conservative treatment.

CONCLUSION

The indications for surgery should be defined by the type of diverticular disease, the aim of surgical treatment, the evaluation of the efficacy of surgical treatment in comparison to conservative treatment and an individual appraisal of the risks.

Predictive model estimating the decrease of postoperative gastrointestinal quality of life index (GIQLI) in patients after elective laparoscopic sigmoid resection for diverticular disease

Background

Growing consideration in quality of life (QoL) has changed the therapeutic strategy in patients suffering from diverticular disease. Patients’ well-being plays a crucial role in the decision-making process. However, there is a paucity of studies investigating patients’ or surgery-related factors influencing the postoperative gastrointestinal function. The aim of this study was to investigate in a predictive model patients or surgical variables that allow better estimation of the postoperative gastrointestinal QoL.

Methods

This observational study retrospectively analyzed patients undergoing elective laparoscopic sigmoidectomy for diverticulitis between 2004 and 2017. The one-time postoperative QoL was assessed with the gastrointestinal quality of life index (GIQLI) in 2019. A linear regression model with stepwise selection has been applied to all patients and surgery-related variables.

Results

Two hundred seventy-two patients with a mean age of 62.30 ± 9.74 years showed a mean GIQLI of 116.39±18.25 at a mean follow-up time of 90.4±33.65 months. Women (n=168) reported a lower GIQLI compared to male (n=104; 112.85±18.79 vs 122.11±15.81, p<0.001). Patients with pre-operative cardiovascular disease (n=17) had a worse GIQLI (106.65 ±22.58 vs 117.08±17.66, p=0.010). Finally, patients operated less than 5 years ago (n=63) showed a worse GIQLI compared to patients operated more than 5 years ago (n=209; 111.98±19.65 vs 117.71±17.63, p=0.014).

Conclusions

Female gender and the presence of pre-operative cardiovascular disease are predictive for a decreased postoperative gastrointestinal QoL. Furthermore, patients’ estimation of gastrointestinal functioning seems to improve up to 5 years after surgery.

[Choice of operative procedure in diverticular disease : Taking the latest treatment strategies into consideration]

BACKGROUND

There are various procedures to be considered in the surgical treatment of complicated diverticulitis, which must be selected depending on the classification of diverticular disease (CDD) type and the condition of the patient.

OBJECTIVE

Comparison of surgical procedures with respect to aspects such as morbidity, mortality, reconstructive surgery and postoperative quality of life.

MATERIAL AND METHODS

Evaluation, analysis and assessment of the current literature on surgical treatment of diverticular disease.

RESULTS

Laparoscopic sigmoid resection with primary anastomosis is now considered the standard procedure for complicated sigmoid diverticulitis. It is preferable to open resection because of the better results of the minimally invasive approach with respect to the incidence of wound infections, abdominal abscesses and the occurrence of fascial dehiscence. In an emergency situation with perforation and peritonitis (CDD type 2c1/2), primary anastomosis with protective ileostomy should be favored over discontinuity resection (Hartmann's procedure). In particular, it must be taken into account that in a large proportion of patients there is no restoration of continuity after Hartmann's operation. The damage control strategy can be used in perforated sigmoid diverticulitis with generalized peritonitis (CDD type 2c1/2). In individual cases, laparoscopic lavage with insertion of a drainage may be considered as a therapeutic treatment strategy for perforated sigmoid diverticulitis with purulent peritonitis (CDD type 2c1).

CONCLUSION

Selection of the surgical procedure for complicated sigmoid diverticulitis remains challenging. Randomized controlled trials of new treatment strategies as well as robotic-assisted surgery should be considered in the choice of surgical procedure in the future.
