Prospective evolution of body compositions based on bioelectrical impedance analysis and water intake on patients with gallstone.

BACKGROUND: We aimed to compare bioelectrical impedance analysis (BIA) body composition and to reveal predictive factors that may help prevent gallstone formation. METHODS: Patients with gallstones by ultrasonography were selected as the case group, while participants without stones were selected as the control group. The body composition of the participants in both groups was measured by BIA. Demographic charac-teristics, mean water intake daily of the participants (MWID) and body mass index (BMI), total body fat mass (TBFM), total body fat percentage (BFP), total body water (TBW), body fat mass of trunk (BFM of trunk), and visceral fat level (VFL) measured by BIA were recorded. Predictive risk factors for gallstone formation were revealed by statistical analysis. RESULTS: The data of a total of 191 participants, including 83 participants in the group with gallstones and 108 participants in the group without gallstones, were analyzed. Both groups were statistically similar in terms of age and sex (P>0.05). In univariate analysis, BMI, TBFM, BFP, BFM of trunk, and VFL were statistically significantly higher (P = 0.007, P=0.004, P=0.003, P=0.003, and P=0.005, respectively) while MWID was lower (P<0.001) in the group with gallstone. In multivariate analysis, MWID (ref: ≥1.5 odds ratio [OR]: 7.786 95% confidence interval [CI]: 3.612-16.781) and BFP (ref: ≥0.24 OR: 3.102 95%CI: 1.207-7.972) were independent factors in gallstone formation. CONCLUSION: The MWID and BFP level measured by the BIA technique, which is an easily applicable, noninvasive method, are independent risk factors for gallstone formation.

Is it necessary to use specimen retrieval bag for reducing surgical site infection in laparoscopic appendectomy?A randomized controlled trial.

BACKGROUND: The aim of the study was to investigate the comparison the effects of the extraction of specimen by using a specimen retrieval bag (SRB) or direct extraction through trochar in terms of surgical site infection (SSI) in patients who underwent laparoscopic appendectomy. METHODS: A total of 165 patients were randomly allocated into two groups. A SRB was used in 77 patients (Group 1, 46.7%) and not used in 88 patients (Group 2, 53.3%). Demographics, comorbid diseases, laboratory results, preoperative diameter of appendix, intraoperative observations, intraoperative procedures, hospitalization times, SSIs, pathology results, culture results, and findings of the patients who developed complications and the treatments given to the patients due to complications during the post-operative period were recorded. RESULTS: The mean age of the patients was 33.95 SD 13.25 (min-max: 18-78) years. No significant difference was observed in the demographics, hospitalization times, distribution of the incidence rates of diabetes mellitus, perioperative perforation, perioperative fluid/abscess, drain insertion, aspiration-irrigation, superficial incisional SSI, drainage requirement, leakage, positive culture results, and post-operative intra-abdominal infection (p>0.05) between the groups. Neutrophil and leukocyte values were statistically significantly different between the groups (p=0.044 and p=0.012, respectively). There was a significant difference between the two groups in terms of the complicated appendicitis (p=0.040). There was no significant difference in terms of the positive culture results and incidence of post-operative intra-abdominal infection between the patients in Group 1 and Group 2 in both the complicated and uncomplicated appendicitis groups (p>0.05). The difference between the patients in Group 1 and Group 2 regarding the incidence of superficial incisional SSI was significant in the uncomplicated appendicitis group (p=0.037), whereas not significant in the complicated appendicitis group (p=1.000). In the multivariate model, only perioperative perforation was observed to be the effective parameter on post-operative intra-abdominal infection at the p<0.05 level (p=0.045). CONCLUSION: The results of the present study revealed that the use of SRB does not prevent microbial seeding in patients who underwent laparoscopic appendectomy; therefore, it was concluded that using SRB is not associated with SSI at laparoscopic appendectomy.

Comparison of single port and three port laparoscopic splenectomy in patients with immune thrombocytopenic purpura: Clinical comparative study.

AIM: Single-port laparoscopic surgery (SILS) has become increasingly popular during the last decades. This prospective study was undertaken to evaluate the feasibility of single-port laparoscopic splenectomy compared with conventional multiport laparoscopic splenectomy. MATERIALS AND METHODS: Between February 2, 2009 and August 29, 2011, a total of 40 patients with the diagnosis of immune thrombocytopenic purpura were included to study. Patients were alienated into two groups according to the procedure type including SILS and conventional multiport splenectomy. RESULTS: There were 19 patients in group 1, and 21 in group 2. Operative time was significantly shorter in group 1 versus group 2 (112.4 ± 13.56 vs 71.2 ±18.1 minutes, respectively, P < 0.05). One patient in group 1 had converted to laparatomy due to preoperative bleeding. Postoperative pain analyses (VAS Score) revealed superiority of SILS in the early post-operative days (P < 0.05). CONCLUSIONS: SILS splenectomy is a safe and effective alternative to standard laparoscopic splenectomy.
