ABSTRACT

BACKGROUND: Hepatobiliary manifestations occur in ulcerative colitis (UC) patients. The effect of laparoscopic restorative proctocolectomy (LRP) with ileal pouch anal anastomosis (IPAA) on hepatobiliary manifestations is debated. AIM: To evaluate hepatobiliary changes after two-stages elective laparoscopic restorative proctocolectomy for patients with UC. METHODS: Between June 2013 and June 2018, 167 patients with hepatobiliary symptoms underwent two-stage elective LRP for UC in a prospective observational study. Patients with UC and having at least one hepatobiliary manifestation who underwent LRP with IPAA were included in the study. The patients were followed up for four years to assess the outcomes of hepatobiliary manifestations. RESULTS: The patients' mean age was 36 ± 8 years, and males predominated (67.1%). The most common hepatobiliary diagnostic method was liver biopsy (85.6%), followed by Magnetic resonance cholangiopancreatography (63.5%), Antineutrophil cytoplasmic antibodies (62.5%), abdominal ultrasonography (35.9%), and Endoscopic retrograde cholangiopancreatography (6%). The most common hepatobiliary symptom was Primary sclerosing cholangitis (PSC) (62.3%), followed by fatty liver (16.8%) and gallbladder stone (10.2%). 66.4% of patients showed a stable course after surgery. Progressive or regressive courses occurred in 16.8% of each. Mortality was 6%, and recurrence or progression of symptoms required surgery for 15%. Most PSC patients (87.5%) had a stable course, and only 12.5% became worse. Two-thirds (64.3%) of fatty liver patients showed a regressive course, while one-third (35.7%) showed a stable course. Survival rates were 98.8%, 97%, 95.8%, and 94% at 12 mo, 24 mo, 36 mo, and at the end of the follow-up. CONCLUSION: In patients with UC who had LRP, there is a positive impact on hepatobiliary disease. It caused an improvement in PSC and fatty liver disease. The most prevalent unchanged course was PSC, while the most common improvement was fatty liver disease.

ABSTRACT

BACKGROUND: This study aimed to evaluate the results of posterior component separation (CS) and transversus abdominis muscle release (TAR) with retro-muscular mesh reinforcement in patients with primary abdominal wall dehiscence (AWD). The secondary aims were to detect the incidence of postoperative surgical site occurrence and risk factors of incisional hernia (IH) development following AWD repair with posterior CS with TAR reinforced by retromuscular mesh. METHODS: Between June 2014 and April 2018, 202 patients with grade IA primary AWD (Björck's first classification) following midline laparotomies were treated using posterior CS with TAR release reinforced by a retro-muscular mesh in a prospective multicenter cohort study. RESULTS: The mean age was 42 ± 10 years, with female predominance (59.9%). The mean time from index surgery (midline laparotomy) to primary AWD was 7 ± 3 days. The mean vertical length of primary AWD was 16 ± 2 cm. The median time from primary AWD occurrence to posterior CS + TAR surgery was 3 ± 1 days. The mean operative time of posterior CS + TAR was 95 ± 12 min. No recurrent AWD occurred. Surgical site infections (SSI), seroma, hematoma, IH, and infected mesh occurred in 7.9%, 12.4%, 2%, 8.9%, and 3%, respectively. Mortality was reported in 2.5%. Old age, male gender, smoking, albumin level < 3.5 gm%, time from AWD to posterior CS + TAR surgery, SSI, ileus, and infected mesh were significantly higher in IH. IH rate was 0.5% and 8.9% at two and three years, respectively. In multivariate logistic regression analyses, the predictors of IH were time from AWD till posterior CS + TAR surgical intervention, ileus, SSI, and infected mesh. CONCLUSION: Posterior CS with TAR reinforced by retro-muscular mesh insertion resulted in no AWD recurrence, low IH rates, and low mortality of 2.5%. Trial registration Clinical trial: NCT05278117.

ABSTRACT

Bioengineered livers (BELs) are an attractive therapeutic alternative to address the donor organ shortage for liver transplantation. The goal of BELs technology aims at replacement or regeneration of the native human liver. A variety of approaches have been proposed for tissue engineering of transplantable livers; the current review will highlight the decellularization-recellularization approach to BELs. For example, vascular patency and appropriate cell distribution and expansion are critical components in the production of successful BELs. Proper solutions to these components of BELs have challenged its development. Several strategies, such as heparin immobilization, heparin-gelatin, REDV peptide, and anti-CD31 aptamer have been developed to extend the vascular patency of revascularized bioengineered livers (rBELs). Other novel methods have been developed to enhance cell seeding of parenchymal cells and to increase graft functionality during both bench and in vivo perfusion. These enhanced methods have been associated with up to 15 days of survival in large animal (porcine) models of heterotopic transplantation but have not yet permitted extended survival after implantation of BELs in the orthotopic position. This review will highlight both the remaining challenges and the potential for clinical application of functional bioengineered grafts.

ABSTRACT

This work discussed the efficiency of endoscopic ultrasonography (EUS) as a diagnostic modality for early detection of pancreatic cancer. The present study was constructed by doing imaging modalities EUS on 24 patients admitted to surgery department in the faculty of medicine with suspected pancreatic malignancy. Pancreatic cancer was found more in older ages above 55 years predominately in males coming from rural areas presenting with abdominal pain with or without jaundice. Histopathological examination revealed that ductal adenocarcinoma represented by 70.83% of cases. This study also shows significant elevation in serum CA19-9 in the presenting cases to confirm a close relation between cancer pancreas and CA19-9 as a good biochemical marker for PC. EUS was found to be able to detect masses less than 20 mm in diameter. Moreover, EUS can accurately detect the mass nature. EUS showed correct information as regards lymph node involvement and vascular invasion which affected the results of respectability of pancreatic masses. Finally, this study clearly showed that EUS is an accurate pre-operative tool in the assessment of nodal staging, vascular invasion, and respectability in patients with pancreatic adenocarcinoma.

ABSTRACT

BACKGROUND: Laparoscopic and rebotic surgery is widely practiced in modern medicine. The operative procedure is not complete until the port sites are closed with a fascial closure. Good fascial closure still represents problem, especially in difficult obese patients. This study reported simple technique is suitable in such cases. MATERIAL AND METHODS: We herein describe a simple technique for fascial closure after Laparoscopic surgery using percutaneous transabdominal approach by using two looped needles in 87 obese patients. This technique was done while the trocar sheath in its position. RESULTS: The procedure was used in 87 patients (69 females and 18 males) after laparoscopic cholecystectomy with mean body mass index 35.5 kg/m2 and mean age 47.1 years from May 2013 through June 2015. No intra-operative incidents and no port sites hernias were reported during a mean follow up of 18 months. CONCLUSION: The procedure is easy to perform, safe, and effective for fascial port site closure in difficult obese (thick abdominal wall and oblique port wound) cases.

ABSTRACT

PURPOSE: The obtaining on the accurate mesh size is the key for the good results and making the procedure easy during laparoscopic hernia repair. This study offers a modified transabdominal external needle technique to achieve this goal. METHODS: During the period from February 2011 through October 2013, during laparoscopic inguinal hernia repair in 41 patients, the mesh dimensions were determined by novel technique. Where, the mesh size was calculated percutaneous transabdominal by using spinal needle No. 22 with thread inside it. The mean follow up period was 24 months. RESULTS: The ages of this patients group were ranged from 21 to 65 years (mean, 49 years). The mean time needed to obtain the accurate mesh dimensions was 3 min. No recurrence or mesh bulging or mesh infection were recorded in this patients group during the period of follow up. CONCLUSION: Our technique for calculation of mesh dimensions during laparoscopic hernia repair is accurate, safe, and easy.

ABSTRACT

BACKGROUND: Acute appendicitis is the most frequent abdominal disease and requires urgent surgery. At the present time, laparoscopic appendectomy is a well-accepted emergency procedure at most centers. In this study, we used a new spiral needle to facilitate the procedure, making it easy, minimally invasive, and cost effective. METHODS: The study included 70 patients of both sexes with acute appendicitis that was treated by laparoscopic appendectomy using a new spiral needle. These cases were treated at the General Surgery Department, Zagazig University, Egypt, from May 2012 to August 2013. In the procedure we used only two ports (a 10-mm port directly below the umbilicus for the camera and a 5-mm port at the left iliac fossa at the midclavicular line). The new spiral needle was used to hold the appendix during the procedure and was inserted into the right iliac fossa depending on the site of the appendix. RESULTS: The mean age of the patients was 27.3 years, mean operative time was 40 min, and mean hospital stay was 1.3 days. Ten patients (14%) had minimal bleeding at the site of needle passage into the mesoappendix. Wound infection at the site of umbilical port occurred in four patients (5.7%) postoperatively. CONCLUSION: Laparoscopic appendectomy using our new spiral needle is easy, minimally invasive, and cost effective.

ABSTRACT

BACKGROUND AND OBJECTIVES: Trocar-site incisional hernias are the most common complications in laparoscopic surgery. Fascial closure of port sites represents a challenging issue in laparoscopic surgery. METHODS: We describe a simple easy technique for fascial closure of port sites using a double-tip needle (Lasheen needle). This study included 100 patients who underwent laparoscopic surgery from January 2009 through August 2011 in the General Surgery Department, Zagazig University Hospital, Zagazig, Egypt. The mean follow-up period was 2 years for any wound complications at these trocar sites. RESULTS: The mean age of the patients was 39.5 years, and the mean time for placement of one suture was 2 minutes. No trocar-site herniation occurred with our technique during the period of follow-up. Infection developed at the trocar site in 3 patients. CONCLUSION: This technique is easy, simple, safe, fast, inexpensive, and effective for fascial closure of trocar sites.
