[Ultrasound diagnosis of chronic paracolic inflammatory mass in diverticular disease]. / Ul'trazvukovaya diagnostika khronicheskogo parakolicheskogo infil'trata pri divertikulyarnoi bolezni obodochnoi kishki.

OBJECTIVE: To evaluate the feasibility of ultrasound in diagnosis of chronic paracolic inflammatory mass in patients with diverticular disease. MATERIAL AND METHODS: We analyzed ultrasonic findings in 216 patients with chronic inflammatory complications of colonic diverticular disease. Chronic paracolic inflammatory mass as the most common and significant chronic complication of diverticular disease was analyzed in 116 patients. Ultrasonic findings were compared with specimen assessment, intraoperative data, irrigoscopy, colonoscopy, endoscopic ultrasound and computed tomography data. RESULTS: Sensitivity of ultrasound for diagnosis of chronic paracolic inflammatory mass was 76,7%, specificity - 100%, overall accuracy - 87,5%. CT and endoscopic ultrasound were the most informative among different diagnostic tools (sensitivity 79,6% and 77,8%, respectively). CONCLUSION: Ultrasonic examination and computed tomography are the most valuable methods for diagnosis of chronic paracolic inflammatory mass in patients with diverticular disease. Ultrasound is a first-line method for diagnosis and follow-up of complicated diverticular disease due to its availability, safety and unnecessary special preparation of patients.

[The role of neutrophil CD64 index in the diagnosis of infectious complications after colorectal resection]. / Rol' indeksa CD64-neitrofilov v diagnostike infektsionnykh oslozhnenii posle rezektsii tolstoi kishki.

OBJECTIVE: To determine diagnostic value of neutrophil CD64 index (iCD64n) in the diagnosis of postoperative infectious complications after colorectal resections. MATERIAL AND METHODS: Seventy-three patients underwent colorectal surgery for the period from January to December 2018. These patients were included into a single-center study. Peripheral blood samples were taken on 3 and 6 postoperative days (POD) to check iCD64n level. We analyzed incidence of postoperative infectious complications, sensitivity (Se) and specificity (Sp) of postoperative iCD64n level on the 3rd and 6th POD. RESULTS: Postoperative infectious complications developed in 10 (13.7%) patients. Median iCD64n was significantly higher (p=0.0017 for POD 3; p=0.018 for POD 6) in patients with infectious complications (1.6 on POD 3; 1.3 on POD 6) compared to those without complications (1.1 on POD 3; 0.9 on POD 6). Area under curve (AUC) on the 3rd POD was 0.8 with the cut-off value of 1.4, Se - 70%, Sp - 93.7% (p=0.002). On the 6th POD, AUC was 0.91 with cut-off value of 1.23, Se - 80%, Sp - 93.7% (p<0.001). CONCLUSION: Neutrophil CD64 index is a valuable predictor for the diagnosis of postoperative infectious complications after colorectal resections. It is a useful tool to ensure a safe early discharge.The study is registered on the website «clinictrials.gov¼ (registration number NCT03559335).

[Short-term outcomes of laparoscopic-assisted procedures for chronic complications of diverticular disease]. / Rezul'taty laparoskopicheski-assistirovannykh vmeshatel'stv pri khirurgicheskom lechenii khronicheskikh oslozhnenii divertikuliarnoi bolezni.

AIM: To estimate efficacy of laparoscopic-assisted procedures for chronic complications of diverticular disease (DD). MATERIAL AND METHODS: It was made a prospective comparative study within 2007-2015. Inclusion criteria were verified chronic DD (>6 weeks after the first attack) and bowel resection followed by primary anastomosis. EXCLUSION CRITERIA: contraindications for pneumoperitoneum, BMI ≥35 kg/m2, infiltrate dimension >10 cm, preoperatively non-excluded neoplasm. RESULTS: 233 patients with chronic DD underwent elective surgery, 136 (58.4%) of them were included in the study. There were 80 (58.8%) females aged 57.2±6.2 (24-83) years. Main group consisted of 75 patients after laparoscopic-assisted procedures, 61 were in control group (open ones). Both groups were homogeneous in age, gender, BMI, type of chronic complications, extent of inflammation, extent of bowel resection, surgery time (211.1 vs 206.3 min; p=0.16), incidence of preventive stoma (12.9 vs 19.7%; p=0.32) and complications rate (10.7 vs 14.7%; p=0.47). Maximal time of surgery was noted in case of chronic abdominal mass with statistically significance for main group (240.0±12.2 min vs 207.6±13.7 min; р=0.01). Conversion rate was 12.0% in main group. Main group showed significant higher rate of stapler anastomoses (66.7 vs 22.9%; р<0.0001), less intraoperative blood loss (100 ml vs 350 ml; р=0.001). Early postoperative period was significantly shorter in main group (9.5±0.4 days vs 12.9±1.2 days, р=0.02). CONCLUSION: Laparoscopic-assisted procedures for diverticular disease are associated with more favorable early postoperative period with the same complication rate. Technical complexity and operative time depend on the extent of pelvic inflammatory changes.

[Colovesical fistula as a complication of diverticular disease].

The results of research on the clinical picture, features of manifestation, diagnosis, and treatment of patients with diverticular disease complicated by sigmovesical fistula are presented. The study included 31 patients (19 [61.3%] men, 12 [38.7%] women), aged 32-83 (55.6 +/- 7.1) years. Diagnostic program included physical examination, laboratory blood and urine tests, endoscopic, radiological, ultrasound examinations. All patients underwent different interventions according to the severity and extent of the inflammatory process, the involvement of other organs of the abdominal cavity and the extent of diverticular lesions of the colon. Long-term results were assessed in all patients in a period of 5 months to 12 years, with a median follow-up 4.7 years. It is shown that the clinical manifestations of intestinovesical fistula did not match the severity of complications, and were subclinical. Timing for referral the patient to coloproctologist was 5 months after the occurrence of first clinical signs. In any case, conservative treatment has not led to spontaneous colovesical fistula closure. Average size of parafistulous infiltration on the wall of the bladder and perivesical tissue was 6.5 +/- 2.4 cm. All the patients underwent different types of colon resection. Postoperative complications did not requiring recurrent surgery were detected in 5 (16.1%) patients. None of these has experienced recurrence complications of diverticular disease. For the optimization the treatment strategy, physicians should follow multidisciplinary approach immediately after revealing the patient with persistent bacteriuria, pneumaturia and fecaluria. The surgery is the method of choice in the treatment of colovesical fistula as a complication of diverticular disease.

[Determination of colon resection limits in diverticulosis]. / Opredelenie granits rezektsii obodochnoi kishki pri divertikuleze.

Results of surgical treatment of 112 patients with colon diverticulosis are analyzed. It is established that during operation it is necessary to perform such scope of resection which permits to create anastomosis between colon parts without their discoordination. The risk of complications from anastomosis decreases to 3.7%. The creation of anastomosis with significant discoordination leads to high risk of its insufficiency. It is desirable to resect the colon's parts with moderate discoordination. When the extension of of resection margins due to parts with moderate discoordination is dangerous, it is possible to create the anastomosis with ileo- or colostoma. In this case the risk of inflammatory complications remains, but conservative treatment of these complications in the conditions of feces efflux is effective.
