Patients and methods Between June 2014 and September 2018, 310 morbidly obese patients have undergone LOAGB surgery. Results The mean operating room time was 69 min. Median postoperative length of stay was 2.1 days. The;Deg;BM;Deg;I has decreased from 49.3±9.9 to 38.8±9.7 kg/m2, 33.7±4.7 and 28.8 kg/m2 at 6, 12, and 24 months postoperatively, respectively. The percentage of excess weight loss is, respectively, 50±26, 62±25, and 72±18% at 6, 12, and 24 months postoperatively.. Major complications have occurred in a total of 11 (3.5%) patients. One patient has suffered from postoperative gastrojejunal anastomotic leakage. Five patients have suffered from massive postoperative bleeding. Two patients have intractable bile reflux after minigastric bypass. Omega loop gastric bypass was converted to Roux-en-Y gastric bypass in these two patients. One anastomoti...

The laparoscopic Roux-en-Y gastric bypass (LRYGB) is the procedure of choice to convert a failed VBG. Materials and Methods Between August 2014 and June 2016, 37 patients (23 females and 14 males) underwent revisional LRYGBs after failed VBGs. Thirty-four patients had open VBGs and two patients had laparoscopic butterfly gastroplasties. These patients completed follow-ups of at least 1 year. Results The median operating time was 164 min (range 132-246), and the mean length of the hospital stay was 2.4 days (range 2-7). The mean body mass index (BMI) of the study group was 42.5 kg/m 2 , while the mean BMI and the percentage of excess body weight loss (%EBWL) for the patients 6 months after the operation were 31.7 kg/m 2 and 52.1%, respectively. The mean BMI and %EBWL for the patients 1 year after the operation were 29.5 kg/m 2 and 67.7%, respectively. There were neither intraoperative complications nor postoperative mortalities, but the overall complication rate was 22% (eight patients). Conclusion An LRYGB following a VBG is technically challenging, but safe, with low morbidity and mortality rates. Moreover, a revisional LRYGB provides excellent weight loss results.

Resection of the antrum is one of these debatable issues. Aim: The study aims at assessing the difference in long and short term weight loss between both antral resection laparoscopic sleeve gastrectomy & antral preservation laparoscopic sleeve gastrectomy. Patients and methods: Is a prospective randomized control study including 100 patients with BMI exceeding 35, fifty of them will undergo antral preservation in laparoscopic sleeve gastrectomy (group A), and the other fifty patients will undergo antral resection in laparoscopic sleeve gastrectomy (group B). Results: Weight loss and BMI reduction after 6 months in the antral resection group were more than the antral preservation group with mean weight 92.25 kg in antral resection group compared to 99.46 kg in antral preservation group and mean BMI 34.48 in antral resection group compared to 39.29 in antral preservation group. Also weight loss and BMI reduction after 12 months in the antral resection group were more than the antral preservation group with mean weight 71.60 kg in antral resection group compared to 77.20 kg in antral preservation group and mean BMI 26.41 in antral resection group compared to 30.71 in antral preservation group. Conclusion: Antral resection in LSG safely potentiates the restrictive effect achieved and may result in greater and better maintained weight loss.

Research paper thumbnail of Porto-Mesenteric Venous Thrombosis (PMVT) Following Laparoscopic Bariatric Surgery: Incidence, Clinical Presentation, Analysis of the etiology and Management in 1434 Cases

Ain Shams Journal of Surgery, 2017

Background: Porto-mesenteric venous thrombosis (PMVT) is a rare but severe surgical complication ... more Background: Porto-mesenteric venous thrombosis (PMVT) is a rare but severe surgical complication developing in patients who underwent laparoscopic bariatric surgery; with difficult diagnosis and potentially severe consequences due to higher risk of bowel infarction. Its clinical presentation, management, and sequelae remain poorly understood. We aimed to describe the incidence, clinical features, management and outcome, in patients with PMVT after laparoscopic bariatric surgery. Patients and methods: This was a retrospective analysis of patients who underwent laparoscopic bariatric surgery for morbid obesity between October 2014 and September 2016 who developed PMVT. Age, sex, body mass index(BMI), personal risk factors for thrombosis, family history of thrombosis, surgical technique, thrombo-embolic prophylaxis, primary surgery outcomes, clinical features and long term postoperative follow up findings were analyzed in this study. The diagnosis was established with an abdominal computed tomography (CT) scan as well as duplex ultrasound of the portal venous system. All patients received longterm anticoagulation. Results: Of 1434 patients who underwent laparoscopic bariatric surgery; 947 patients underwent laparoscope sleeve gastrectomy (LSG) while 487 underwent laparoscopic mini-gastric bypass (LMGBP). 4 patients of those who underwent LSG (0.42%) developed PMVT. On the other hand no patients experienced PMVT following LMGBP. Three patients were males, the mean age was 34 years, and the mean body mass index was 43 kg/m 2. The time of onset of symptoms was within one to two weeks post operatively in 3 cases while one case (the female patient) presented late after 86 days and the presentation was atypical and rapidly progressive and the patient died within two weeks. New-onset epigastric pain was present in all patients, while other signs and symptoms were variable. Ultrasonography and computed tomography scan were performed and were diagnostic in all cases. The decision regarding the type of drug and the duration of anticoagulation therapy was based on hematology consultant assessment as regards patients' clinical course, result of thrombophilic evaluation, presence of other thrombotic risk factors and follow-up Doppler studies. One patient underwent surgical intervention: laparotomy with splenectomy and necrotic small-bowl resection. One patient died. Conclusion: PMVT is a rare but serious complication after LSG. Familiarity with this dangerous entity is important. It requires early diagnosis and management as these cases carry significant morbidity and mortality. Prompt diagnosis and anti-coagulation therapy led to favorable outcomes in most cases. Significantly lower rates of thrombosis were found in patients who received an extended course of anticoagulation.

It has the potential to cause reduced postoperative pain, reduce abdominal wall trauma and increase the aesthetic result without compromising the outcome. This review describes the feasibility, present situation and challenges faced as well as standardized procedures and the future prospects of reduced port laparoscopic gastrectomy for various bariatric procedure. Materials and methods: From December 2015 to January 2017, 251 patients were enrolled in our trial all of which underwent the procedure using the three port technique. All patients had morbid obesity with history of failure of conservative treatment. The aim was to assess and evaluate postoperative pain and patients' satisfaction with the aesthetic results as well as to define the features of early post-operative complications of patients in comparison to the conventional five ports technique. Results: 251 patients were enrolled in our trial. The analyzed population included 185 women and 66 men. Mean age and BMI were 41 ± 23 and 53 ±18, respectively. Mean operative time was 47 ± 20 min for sleeve gastrectomy, 65±13 min for mini-gastric bypass and 133±25 min for revisional surgeries. Mortality was nil. Overall morbidity rate was recorded. Median duration of hospital stay was 1.5 days (range, 1-2) for sleeve gastrectomy and gastric bypass and 2.5 days (2-4 days) for revisional surgeries. Conclusion: Three ports technique for bariatric surgery is a safe and effective surgical option in patients with morbid obesity without additional early surgical complications or increase in operative time, and with a greater patient aesthetic satisfaction.
