[Smoldering diverticultis - still a type of chronic recurrent diverticulitis with good indication for surgery? - Surgery for smoldering diverticulitis]. / Smoldering-Divertikulitis ­ doch eine Form der chronisch-rezidivierenden Divertikulitis mit guter Operationsindikation?

BACKGROUND: Elective surgery for recurrent uncomplicated diverticulitis is a matter of debate. "Smoldering diverticulitis" (SmD) describes a subtype of the disease which is characterized by frequently relapsing symptoms triggered by a "smoldering fire-like" ongoing inflammatory process. The aim of this study was to investigate the value of surgery in these patients. METHODS: Forty-four patients with the clinical signs of SmD were selected from a prospective database of 393 patients with elective surgery for diverticulitis. They were compared for morbidity and the effect of surgery on quality of life (QL) (Gastrointestinal QL-Index (GLQI)) with a group of 95 patients who had elective surgery for perforated diverticulitis. RESULTS: Morbidity was equivalent in both groups with shorter durations of surgery in the SmD group (159 (65-301) vs. 174 (100-443) minutes, p = 0.031). Six months after surgery, a significant improvement of QL was found in the SmD group (GLQI 115 (72-143) vs. 98 (56-139) preoperatively, p = 0.018). In the control groups, only a non-significant improvement of the preoperatively less suppressed quality of life was noted. Approximately 80 % of the patients were satisfied with the outcome of surgery. CONCLUSION: In patients with SmD like chronic recurrent disease surgery is effective to improve quality of life.

Single-incision laparoscopic surgery for diverticulitis in overweight patients.

AIM: Single-incision laparoscopic surgery (SILS) has been introduced as a new technique for the treatment of various colorectal diseases. Recurrent or complicated diverticulitis of the sigmoid colon is a frequent indication for minimally invasive sigmoid colectomy. The aim of this study was to investigate the impact of obesity on the outcome of SILS sigmoid colectomy. METHODS: From September 2009 to October 2014, data from 377 patients who had intended SILS sigmoid colectomy for diverticulitis at our institution were collected in a prospective database. The patients were categorized in the following subgroups: group 1 (normal weight, body mass index (BMI) < 25 kg/m(2)), group 2 (overweight, BMI 25-29.9 kg/m(2)), group 3 (obesity, BMI 30-34.9 kg/m(2)), and group 4 (morbid obesity, BMI > 35 kg/m(2)). RESULTS: The groups were equivalent for sex, age, status of diverticulitis, the presence of acute inflammation in the specimen, and the percentage of teaching operations, but the percentage of patients with accompanying diseases was significantly more frequent in groups 2, 3, and 4 (p = 0.04, 0.008, and 0.018, respectively). As compared to group 1, the conversion rate was significantly increased in groups 2 and 4 (2.3 vs. 9.3% (p = 0.013) and 2.3 vs. 12.5% (p = 0.017), respectively). The duration of surgery, hospitalization, and morbidity did not differ between the four groups. CONCLUSION: Up to a body mass index of 35 kg/m(2), increased body weight does not significantly reduce the feasibility and outcome of single-incision laparoscopic surgery for diverticulitis.
