Choosing the cosmetically superior laparoscopic access to the abdomen: the importance of the umbilicus

Background: Single-incision laparoscopy (SIL) is a rapidly growing procedure in the field of surgery. The most frequent site of abdominal access is the umbilicus. Its appearance can be altered during SIL procedures. The literature suggests that the umbilicus plays an important role in the overall physical appearance of patients. This study therefore investigated the perception of the general population regarding the cosmetics of the umbilicus. Methods: An online survey with 10 questions about the aesthetic importance of the umbilicus was circulated worldwide in both the English and French languages. All the answers then were gathered and analyzed. Results: The majority of the participants considered both their umbilicus and that of their partner as "unimportant.” The total loss of their umbilicus and any undesired changes in its size, shape, and skin color were considered disturbing by most participants, but not its depth. In this survey, 39% of the women and 29% of the men agreed on a negative impact of an undesired change in their umbilicus, whereas 19% of the women and 36% of the men agreed on a negative impact of such a change in the umbilicus of their partner. The majority of the participants did not consider the umbilicus as playing a major role in sexual attractiveness. Conclusions: The majority of the participants gave a limited cosmetic role to the umbilicus and would therefore be good candidates for an umbilical surgical access. Among the minority of participants who considered the umbilicus to be cosmetically important, the men tended to be more concerned about the aesthetic aspect of their partner's umbilicus, and a one-third of them agreed on its role in sexual appeal. Although not the majority, a significant proportion of participants were sensitive about the aspect of their umbilicus. Special care should be given to identify this population and choose the appropriate minimally invasive acces

Laparoscopic versus open sigmoid resection for diverticulitis: long-term results of a prospective, randomized trial

Background: Elective laparoscopic sigmoid resection for diverticulitis has proven short-term benefits, but little data are available from prospective randomized trials regarding long-term outcome, quality of life, and functional results. Methods: Of 113 patients randomized to undergo laparoscopic (LAP) versus open (OP) sigmoid resection for diverticulitis, 105 (93%, LAP=54, OP=51) patients were examined and answered the Gastrointestinal Quality of Life Index (GIQLI) questionnaire, with a median follow-up of 30 (range, 9-63) months after surgery. Results: Incisional hernias were detected in five (9.8%) patients in the OP group versus seven (12.9%) in the LAP group, P=0.84). Overall satisfaction with the operation on a scale of 0 (very poor) to 10 (excellent) was 9 (range, 2-10) in the OP group versus 9 (range, 2-10) in the LAP group (P=0.78). Median GIQLI score was 115 (range, 57-144) in the OP group versus 110 (range, 61-134) in the LAP group (P=0.17). Overall satisfaction with the cosmetic aspect of the scar on a scale of 0 (very poor) to 10 (excellent) was 8 (range, 1-10) in the OP group versus 9 (range, 0-10) in the LAP group (P=0.01). Finally, median hospital cost (including reoperations for hernias) was 11,606 (5,230-147,982) CHF in the LAP group versus 12,138 (6,098-39,786) CHF in the OP group (P=0.47). Conclusions: Both open and laparoscopic approaches for sigmoid resection achieve good long-term results in terms of gastrointestinal function, quality of life, and patients' satisfaction. Significant long-term benefits of laparoscopic surgery are restricted to cosmetic (ClinicalTrials.gov protocol #NCT00453830

Who Should Do NOTES? Initial Endoscopic Performance of Laparoscopic Surgeons Compared to Gastroenterologists and Untrained Individuals

Introduction: Natural orifice transluminal endoscopic surgery (NOTES) is a multidisciplinary surgical technique. If conventional endoscopic instrumentation can be easily mastered, surgeons with laparoscopic experience could head NOTES interventions. Materials and Methods: Thirty individuals were tested for endoscopic dexterity. Group 1 included seven gastroenterologists, group 2 included 12 laparoscopically experienced surgeons lacking endoscopic experience, and group 3 included 11 interns who had no hands-on endoscopic or surgical experience. Each individual repeated an easy (T1), medium (T2), and difficult (T3) task ten times with endoscopic equipment on a NOTES skills-box. Results: Group 3 had significantly poorer performances for all three tasks compared to the other groups. No significant differences were seen between groups 1 and 2 for T1 and T2. The initial T3 performance of group 1 was better than that of group 2, but their performance after repetition was not statistically different. Groups 2 and 3 improved significantly with repetition, and group 2 eventually performed as well as group 1. Conclusions: The data indicate that laparoscopic surgeons quickly learned to handle the endoscopic equipment. This suggests that a lack of endoscopic experience does not handicap laparoscopic surgeons when performing endoscopic tasks. Based on their knowledge of anatomy and the complication management acquired during surgical education, surgeons are well equipped to take the lead in interdisciplinary NOTES collaboration

Investigation of Vitamin D Levels in Patients with Vitiligo Vulgaris

The aim of the study was to investigate serum 25-hydroxyvitamin D (25(OH) D3) levels in patients with vitiligo vulgaris in terms of causal relation and extension of the disorder.This study is a clinical cross-sectional study carried out in order to determine 25-hydroxyvitamin D levels among 25 patients with vitiligo vulgaris and in 41 controls. Fitzpatrick skin phototypes, history of autoimmune disease, family history of vitiligo, and duration of the disease were also evaluated.The mean levels of vitamin D in patient and the control group were 15.2±5.2 ng/dL and 14.4±6.2 ng/dL respectively (P&gt;0.05). In our study, 48% of the patients had insufficient (&lt;30 ng/mL) and 52% had very low (&lt;15 ng/mL) levels of vitamin D. There was no correlation between age, duration of the disease, and body surface area affected with vitamin D levels. There was no significant difference in vitamin D levels between patients who had family history of vitiligo (5 patients, 20%) and those that did not.Vitamin D levels were found to be insufficient (&lt;30 ng/mL) or very low (&lt;15 ng/mL) in most of the patients with vitiligo vulgaris, but not statistically significantly different as a group when compared to the controls. More studies are needed to differentiate between the effects of low vitamin D levels on pathogenesis of vitiligo vulgaris and lower vitamin D levels as a result of the disease. </p

Desferrioxamine Reduces Oxidative Stress in the Lung Contusion

Our hypothesis in this study is that desferrioxamine (DFX) has therapeutic effects on experimental lung contusions in rats. The rats were divided into four groups (n=8): control, control+DFX, contusion, and contusion+DFX. In the control+DFX and contusion+DFX groups, 100 mg/kg DFX was given intraperitoneally once a day just after the contusion and the day after the contusion. Contusions led to a meaningful rise in the malondialdehyde (MDA) level in lung tissue. MDA levels in the contusion+DFX group experienced a significant decline. Glutathione levels were significantly lower in the contusion group than in the control group and significantly higher in the contusion+DFX group. Glutathione peroxidase (GPx) and superoxide dismutase (SOD) levels in the contusion group were significantly lower than those in the control group. In the contusion+DFX group, SOD and GPx levels were significantly higher than those in the contusion group. In light microscopic evaluation, the contusion and contusion+DFX groups showed edema, hemorrhage, alveolar destruction, and leukocyte infiltration. However, histological scoring of the contusion+DFX group was significantly more positive than that of the contusion group. The iNOS staining in the contusion group was significantly more intensive than that in all other groups. DFX reduced iNOS staining significantly in comparison to the contusion group. This study showed that DFX reduced oxidative stress in lung contusions in rats and histopathologically ensured the recovery of the lung tissue

Pyoderma gangrenosum after totally implanted central venous access device insertion

<p>Abstract</p> <p>Background</p> <p>Pyoderma gangrenosum is an aseptic skin disease. The ulcerative form of pyoderma gangrenosum is characterized by a rapidly progressing painful irregular and undermined bordered necrotic ulcer. The aetiology of pyoderma gangrenosum remains unclear. In about 70% of cases, it is associated with a systemic disorder, most often inflammatory bowel disease, haematological disease or arthritis. In 25–50% of cases, a triggering factor such as recent surgery or trauma is identified. Treatment consists of local and systemic approaches. Systemic steroids are generally used first. If the lesions are refractory, steroids are combined with other immunosuppressive therapy or to antimicrobial agents.</p> <p>Case presentation</p> <p>A 90 years old patient with myelodysplastic syndrome, seeking regular transfusions required totally implanted central venous access device (Port-a-Cath^®) insertion. Fever and inflammatory skin reaction at the site of insertion developed on the seventh post-operative day, requiring the device's explanation. A rapid progression of the skin lesions evolved into a circular skin necrosis. Intravenous steroid treatment stopped the necrosis' progression.</p> <p>Conclusion</p> <p>Early diagnosis remains the most important step to the successful treatment of pyoderma gangrenosum.</p
