[Cholecystostomy in acute cholecystitis in modern surgical practice]. / Kholetsistostomiya pri ostrom kholetsistite.

OBJECTIVE: To improve the results of treatment of acute cholecystitis. MATERIAL AND METHODS: A historical cohort study (1965-2016) included 1248 patients with acute obstructive cholecystitis and 154 patients with acute obstructive cholecystitis combined with ductal complications and obstructive jaundice. Cholecystostomy was used in all patients. A systematic review of the evidence base on the use of cholecystostomy in high-risk patients was carried out. RESULTS: Cholecystostomy through laparotomy was performed in 240 patients for the period 1965-1981. Overall mortality was 3.6%. Staged treatment strategy has been applied since 1982. Laparoscopic cholecystostomy followed by cholecystectomy through laparotomy was performed in 225 patients for the period from 1982 to 1992. Overall mortality rate was 3.2%. Laparoscopic cholecystostomy (n=617) followed by staged laparoscopic cholecystectomy has been applied for the period from 1993 to 2007. Overall mortality decreased up to 1.1%. Indications for laparoscopic cholecystostomy and staged treatment have been limited since 2008 (n=166). Overall mortality rate was 0.6%. The maximum postoperative mortality after cholecystostomy in some years reached 14.8%.Simultaneous surgeries through laparotomy in patients with acute obstructive cholecystitis and ductal complications were followed by mortality rate 8%, staged laparoscopic cholecystostomy and other minimally invasive technologies (endoscopic papillosphincterotomy with lithoextraction and laparoscopic cholecystectomy) - 4.7%. CONCLUSION: External drainage of the gallbladder is more effective as additional method within staged minimally invasive treatment of complicated cholecystitis rather separate operation. Further analysis of treatment of high-risk patients with acute cholecystitis (as most often selected for cholecystostomy) is required considering the absence of evidence base on this issue.

[Surgical treatment of ulcerative pyloroduodenal stenosis]. / Khirurgicheskoe lechenie iazvennogo piloroduodenal'nogo stenoza.

AIM: To obtain the most reliable information about surgical treatment of ulcerative pyloroduodenal stenosis based on the methodology of evidence-based medicine. MATERIAL AND METHODS: Searching platforms were elibrary, Cochrane Library and PubMed database. The probability of major systematic errors in randomized controlled trials (RCTs) was evaluated. RESULTS: Systematic review included 20 RCTs for the period 1968-2009 with overall sample of 1794 patients. Evaluation of external validity allows to generalize the results of these studies to the entire population of patients with ulcerative pyloroduodenal stenosis. Assessment of internal validity based on the number of systematic errors showed that 7 (35%) of 20 of RCTs corresponded to the highest level of evidence (level 1), 13 (65%) of 20 had systematic errors and were downgraded in the rating (level 1-). Significant heterogeneity of RCTs impedes metaanalysis. Conclusions and practical recommendations for the treatment of ulcerative pyloroduodenal stenosis are formed according to the results of individual RCTs. CONCLUSION: Selective vagotomy may be performed for functional stenosis. In case of organic stenosis, truncal vagotomy should be combined with drainage surgery (pyloroplasty, gastroenterostomy) or Roux/Billroth-1 antrectomy. Treatment of decompensated stenosis within evidence-based medicine is unclear. We have not identified target researches with evidence level 1 for this form of stenosis.

[Perforated cholecystitis. Classification and atypical clinical forms]. / Perforativnyi kholetsistit. Klassifikatsiia i atipichnye klinicheskie formy.

AIM: To obtain new data for diagnosis and treatment of patients with perforated cholecystitis. MATERIAL AND METHODS: It was analyzed the variants of original classification of perforated cholecystitis by Fedorov S.P. - Neimeier O.W. (1934). Moreover, we have assessed treatment of 292 patients with gallbladder perforation (own material of Faculty Surgery Clinic). RESULTS: According to continuous 20-year follow-up perforated cholecystitis was observed in 2.9% of patients with various forms of gallbladder inflammation (n=292 out of 10 215). The frequency of atypical clinical forms of gallbladder perforation including multiple and combined perforation, perforation with acute intestinal obstruction and intraabdominal bleeding was 10% (n=29 of 292). Overall mortality in atypical clinical forms related to whole cohort with perforated cholecystitis was 2% (n=6 of 292). CONCLUSION: Atypical clinical forms of gallbladder perforation require specific treatment strategy due to the need for emergency surgical interventions. At the same time, the possibilities of video-assisted surgery are somewhat limited compared with other forms of gallbladder inflammation and can be used only in a third of patients.
