Aim: This study aimed to analyze the results of bilateral inguinal hernia laparoscopic TAPP repair utilizing a single mesh against a single mesh for each defect. Patients and Methods: Six months of follow-up were conducted on the 60 patients who underwent laparoscopic TAPP repair for bilateral inguinal hernias and were admitted to the general surgery outpatient clinic at Benha University Hospital. There were two equal groups of patients: Patients in group A had bilateral inguinal hernias repaired by laparoscopic TAPP utilizing a single mesh. Patients in group B had laparoscopic TAPP repair of bilateral inguinal hernias, with a single mesh used for each abnormality. Results: Group B’s mesh insertion time was much longer ( P=0.019 ). Tacking staples utilized for mesh fixing were significantly less in group A ( P<0.001 ). Group A exhibited consistently decreased postoperative pain levels on the 1 st , 2 nd , 3 rd , 4 th , and 5 th days ( P<0.05 ). Group A patients consumed much fewer analgesics ( P<0.001 ), and they recovered to normal activity more quickly ( P<0.001 ). In group A, seroma development was much less common ( P=0.026 ). Conclusion: For bilateral inguinal hernias, utilizing a single big mesh in TAPP will make fixation simpler, need fewer tacking stables, and lessen discomfort. For bilateral inguinal hernia, laparoscopic TAPP with a single big mesh is a secure, efficient, and economical method.","PeriodicalId":22550,"journal":{"name":"The Egyptian Journal of Surgery","volume":"7 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141701200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amin El Masry, Ahmed Haitham","doi":"10.21608/ejsur.2024.357135","DOIUrl":"https://doi.org/10.21608/ejsur.2024.357135","url":null,"abstract":". ABSTRACT Background: Obesity is currently a pandemic that continues to increase all over the world. Nutritional disorders are among the obesity-related adverse events, with vitamin D insufficiency or deficiency being the most frequently encountered one. The aim of the current study was to assess the prevalence of reduced vitamin D levels in Egyptian patients with obesity who were candidates for bariatric surgery and to assess the relation between these levels and the patients’ characteristics. Patients and Methods: This is a retrospective study that included patients with obesity who were recruited for bariatric surgery. The patient’s medical files were screened for demographic and clinical data, including data regarding vitamin D status. Results: This study included 426 patients who were eligible for the study. The patients’ vitamin D levels ranged from 4 to 50 ng/ml, with a mean of 30.2±13.7 ng/ml. A statistically significant lower mean vitamin D levels were shown in females ( P=0.006 ), patients with extreme obesity ( P=0.021 ), diabetes mellitus ( P=0.014 ), and polycystic ovary syndrome ( P=0.016 ). Patients with depression also showed lower mean levels of vitamin D, with marginal statistical significance ( P=0.056 ). Conclusion: This study confirms the high prevalence of abnormally low vitamin D levels in patients with obesity who were candidates for bariatric surgery. The study highlighted differences based on sex and revealed connections between low vitamin D levels and conditions like type 2 diabetes mellitus, polycystic ovary syndrome, depression, and eligibility for bypass surgeries.","PeriodicalId":22550,"journal":{"name":"The Egyptian Journal of Surgery","volume":"8 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141703694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To get the intended outcome, these procedures frequently make use of undetectable grafts and stitching methods. The literature provides a thorough description of the earlier techniques. Among these later methods, the columellar strut continues to be a widely used and successful type of invisible graft in rhinoplasty. The goal of this research is to clarify whether or not the columellar strut graft is a necessary step in maintaining tip support during a primary rhinoplasty. Aim: Debatable has been the impact of a columellar strut graft on the ultimate location of the nasal tip. The objective of this research was to conduct a prospective analysis of thirty consecutive primary rhinoplasty instances, both with and without the use of columellar strut grafts. The study specifically aimed to compare the changes in nasal tip position that occurred before and after surgery. Patients and Methods: The Plastic, Burn, and Maxillofacial Surgery Department at Ain Shams University Hospital carried out this 2-year, two-arm, randomized control clinical study between 2020 and 2022. There were two groups: the first had a rhinoplasty with a columellar strut, while the second group had surgery without a strut graft. Results: The examination of the changes in nasal tip rotation and projection was the primary focus of postoperative assessment. This was achieved by measuring and comparing the nasolabial angle and Goode ratio (preoperative and 6 months postoperative). With the columellar strut group, we saw a considerable improvement in tip rotation and projection postoperatively, which was in line with the patient’s satisfaction with the ultimate cosmetic results. Conclusion: This study shows that, when compared with preoperative measurements, postoperative nasal projection and the nasolabial angle (NLA) are raised and stabilized. This implies that the columellar strut graft is a useful tool for supporting the nasal tip and improving the success of rhinoplasty.","PeriodicalId":22550,"journal":{"name":"The Egyptian Journal of Surgery","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141709591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the effectiveness of interrupted suturing, compared with continuous suturing of the posterior wall of the anastomosis, regarding primary and secondary outcomes of HJ anastomosis. Patients and Methods: Sixty patients were allocated to two groups, each group comprising 30 patients where in group A (Interrupted Suture, n=30), 4/0 polydioxanone sutures were used. In group B (continuous Suture, n=30), 4/0 proline sutures were used. In addition, in all cases interrupted sutures 4/0 polydioxanone were used in the anterior wall of anastomosis to decrease postoperative stricture incidence, then all patients were followed up until the end of data analysis (6 months after HJ anastomosis) using a standardized data collection sheet. Results: The primary postoperative outcomes: Regarding the incidence of leakage, the continuous group (13.3%) had a lower rate of postoperative biliary leak than the interrupted group (16.7%). Regarding the incidence of stricture of anastomosis, two (6.7%) cases had strictures in the interrupted group, whereas there were four (13.8%) strictures in the continuous group. This suggests that the interrupted group had a lower risk of postoperative strictures than the continuous group. Regarding secondary outcomes, the mean number of sutures of the posterior wall was six in the interrupted group, while it was two in the continuous group which means the continuous group was better than the interrupted group as regards cost and time consumed during anastomosis. Conclusion: Postoperative outcomes in HJ vary with interrupted and continuous suture techniques. The continuous sutures revealed lower postoperative biliary leakage, and had better time and cost-effectiveness, while the interrupted sutures had lower incidence of stricture formation.","PeriodicalId":22550,"journal":{"name":"The Egyptian Journal of Surgery","volume":"212 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141692642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of the predominance of biliary atresia and the small size of donor ducts, Roux-en-Y hepaticojejunostomy has been the standard procedure for biliary reconstruction in pediatric LDLT. However, duct-to-duct (D2D) reconstruction is suggested to have less risk of biliary contamination and shorter operative time. In our study, we compare D2D and Roux-en-Y hepaticojejunostomy as regards biliary outcome. Patients and Methods: A retrospective cohort study was conducted on pediatric LDLTs between July 2015 and December 2022. In all, 107 cases were divided into two groups according to the type of biliary anastomosis: group A included 53 recipients who had stentless D2D biliary anastomosis compared with group B including 54 recipients, who underwent Roux-en-Y hepaticojejunostomy. Results: The incidence of biliary-related complications was higher in the D2D group reaching 44.4%, double that recorded in the H-J group (22.8%, P=0.011 ). The incidence of biliary leakage alone was significantly higher (61.5%, n=8/13) in the H-J group versus 8.7% (n=2/23) in the D2D group ( P=0.027 ). Biliary anastomotic stricture alone represented 39.1% (n=9/23) of the biliary complications in D2D groups and only 23.1% (n=3/13) in the H-J group ( P=0.014 ), and it was accompanied by leakage in 26.1% (n=6/23) in the D2D group and 7.7% (n=1/13) in H-J groups and had been proceeded by leakage in a similar number of cases ( P=0.093 ). Most of the biliary complications (84.6%, n=11) ( P=0.050 ) in the H-J group were diagnosed early (<3 months), while in the D2D group, the incidence was nearly equally distributed between early and late presentations (56.5 vs. 43.5%, respectively) ( P=0.030 ). Biliary-related mortality was nearly similar in both groups (8.7 vs. 7.7%) ( P=0.558 ). Conclusion: The D2D anastomosis seems to be a safe and feasible method of biliary reconstruction in pediatric LDLT and harbors multiple advantages over H-J, especially the ability to use Endoscopic retrograde cholangio pancreatography (ERCP) in the management of Biliary Complications (BCs). Our study showed a relatively high rate of postoperative BCs, which was the most among patients who had undergone D2D biliary reconstruction. As these complications can be managed safely and effectively, D2D biliary reconstruction can be the method of choice for pediatric patients with suitable bile ducts for reconstruction and surgeons should master both techniques.","PeriodicalId":22550,"journal":{"name":"The Egyptian Journal of Surgery","volume":"10 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141693995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
