Surgical treatment of acute cholecystitis in obese patients.

<b>Introduction:</b> In today's technological climate, science and medicine have entered a new era. At the level of technological progress, we have identified millennia of "new" problems and diseases. If earlier diseases had a certain individuality then, in the third millennium, we face compliance and synergistic influence of diseases. Obesity is a problem of the third millennium. It is known that obesity is the main factor in the development of various chronic diseases [1-3]. With excess weight and obesity, bile is oversaturated with cholesterol, resulting in an increase of its lipogenicity index. As a result, frequency of gallstone disease increases; findings from this study document an increase of disease frequency as high as 50% to 60% [4]. In 20% of patients, housing concerns are combined with obesity [5]. Thus, obesity is one of the factors in the development of cholelithiasis and cholecystitis [6]. The presence of acute cholecystitis represents the most difficult situation for patients with gallstones. When obesity is also present, the patient's risk of surgical complications increases due to altered homeostasis and reduced reserve capacity [7]. A retrospective study of this issue [8] posed a number of questions about the possibility of influencing the course of disease in the preoperative period as well as the improvement and impact of surgical technicalities in patients with acute cholecystitis and obesity. Addressing these and additional questions is the main goal of this study. <br><b>Aim: </b>The aim of the study was to study and select the optimal method of surgery in patients with acute cholecystitis and obesity. <br><b>Materials and methods:</b> In our study, a prospective analysis was used. We analyzed 67 cases with diagnosis of acute cholecystitis and obesity; all were treated at Kyiv Regional Clinical Hospital in the period from September 2018 to March 2020. Patients with acute cholecystitis and obesity received either traditional or modified laparoscopic cholecystectomy. <br><b>Results:</b> Retrospective analysis indicates traditional laparoscopic cholecystectomy is technically difficult and costly in patients with acute cholecystitis and obesity. A modified laparoscopic cholecystectomy has been proposed to improve and enhance surgery in patients with acute cholecystitis and obesity. Surgical duration was shortened by 9.01 ± 0.41 minutes (p = 0.001; αα= 0.05) when a modified laparoscopic cholecystectomy was performed. <br><b>Conclusions:</b> Performing a modified laparoscopic cholecystectomy reduced the duration of surgery by 9.01 ± 0.41 minutes (p = 0.001; α = 0.05), prevents development of metabolic acidosis pH 7.39 ± 0.03 vs 7.30 ± 0.005 = 0.001; αα= 0.05, pCO2 5.05 ± 0.36 vs 6.03 ± 0.38 (p = 0.02; αα= 0.05), reducing the risk of hypercoagulation. Modified laparoscopic cholecystectomy (LHE) is effective in II and III degrees of obesity (p = 0.001; α = 0.05).

Features of the course of acute pancreatitis in patients with obesity.

PURPOSE: The purpose of the study is to investigate the course of acute pancreatitis in obese patients, the development of local and systemic complications and mortality rates. MATERIALS AND METHODS: We took and analyzed 482 histories of acute pancreatitis treated at Kyiv Regional Clinical Hospital from January 1, 2011 to February 2, 2019. The data were statistically processed in the Excel 2010 program using a descriptive method applying relative, absolute numbers, mean square deviations and their errors. A correlation between variables was studied using the Pearson's test (R2). The significance of the difference between the two independent groups was tested with Student's t-test. RESULTS: We included 482 patients in our study, i.e. 260 patients (54%) with obesity (the study group), and for comparison, 222 (46%) patients with normal body mass, constituting a control group. Obese patients had a higher mean age (55.4 ± 9.4 years, P = 0.01); also, they showed a statistically higher incidence of severe course of acute pancreatitis [85 (32.7%) vs. 16 (7.2%); P = 0.01*]. We noted an increase in the rate of acute pancreatitis with severe course in obese patients with mass gain (from 10.20% to 53.93%, P = 0.03*). Hospitalization time of obese patients was longer than in case of patients with normal body mass. In addition, we observed a two-fold longer hospitalization of obese patients at intensive care units (5.8 ± 0.8 vs. 2.7 ± 0.5 days, P = 0.01*). When investigating the mortality rate, we found out that the main cause of death was the progression of organ failure - 30 cases (6.3%), pulmonary embolism (TB) - 15 (3.1%) and DIC - 18 (3.7%). C onclusions: The presence of obesity in patients involves a high risk of severe acute pancreatitis. This risk increases with body mass increase. In addition, in obese patients the hospitalization and in-patient care takes longer, which increases the total cost of treatment and requires a cost-effective algorithm in the future. A high mortality rate in obese patients requires an improved treatment algorithm.
