“…For instance, in the current study, seven original research papers have been referred to about the relationship between limb length and the result of surgery. The method of measurement was not disclosed in five studies (3,(12)(13)(14)17). In one study, a rubber band was used for measurement (15).…”

“…They reported that OAGB with a 200 cm biliopancreatic limb was associated with a higher rate of protein-calorie malnutrition compared to a 160 cm biliopancreatic limb. Slagter et al ( 13 ) found that attained BMI was higher in OAGB patients with a 200 cm biliopancreatic limb compared to those with a 150 cm or 180 cm biliopancreatic limb. Shah et al ( 14 ) investigated the outcome of LRYGB based on the total length of the alimentary and biliopancreatic limbs.…”

BackgroundMeasurement of small bowel length is an essential step in performing bariatric surgery. Surgeons need to measure bowel length in order to create alimentary and biliopancreatic limbs. Inaccurate bowel measurement may affect the outcome of surgery. However, it is not clear how accurate the measurement of bowel length is by surgeons.MethodsTwo image quizzes marking certain lengths of jejunum were sent to participants. They were asked to estimate the length of marked bowels in maze quizzes. The Error of estimation, prevalence of significant error (error greater than 30 percent of actual length), and the relationship between different participant characteristics was investigated.ResultsA total of 86 participants answered the questionnaire. The mean error of estimation was 4.62 cm (27%). Twenty-eight participants (33%) had significant errors in estimation of bowel length.ConclusionWhile there are surgeons that can estimate bowel length with decent accuracy, significant errors in estimation of bowel length are not uncommon among surgeons. Surgeons should consider adopting techniques for accurate measurement of the small intestine.

Introduction: Bariatric surgeries are effective in treating obesity and its associated co-morbidities. The ideal bariatric surgery with satisfactory weight or BMI loss and with few complications and nutritional deficiencies still does not exist. Modifications in one anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB) are still under study for best BMI loss with few complications. Objective: The aim of the current work was to compare both surgeries, OAGB and RYGB, after limb length modification regarding postoperative complications, resolution of comorbidities, BMI and weight loss, and operative time. Patients and Methods: In this prospective cohort study, we reviewed medical records of 200 patients undergoing mini gastric bypass (MGB) and RYGB with limb length modification. Patients were then followed postoperatively for BMI loss, estimated weight loss, resolution of comorbidities, and postoperative complications. Patients were phone called and asked to attend next day for follow-up. Results: A total of 200 patients were included. Thirteen patients were lost during follow-up. OAGB group has a statistically significant lower BMI and weight at 3, 6, 12, 24 months compared to RYGB group. Regarding operative time, minutes, OAGB group has a significantly lower operative time compared to RYGB group (p=0.0001). Patients who had OAGB had a significantly higher EWL compared to RYGB at 3, 6, 12, 24 months. Regarding resolution of comorbidities and postoperative complications, no significant difference between both groups, MGB vs RYGB (p=0.89) and (p=0.98), respectively. Conclusion: It could be concluded that OAGB is superior to RYGB in BMI and excess weight loss at 3, 6, 12, 24 months, OAGB had lower operative time. No difference between both surgeries in postoperative complications and resolution of comorbidities.

“…Mean %TWL is 32% at 1–2 years, then decreases slightly to 25% at 10 years and maintains this up to 20 years post-op [ 4 ]. Many clinical trials that compared different limb lengths of gastric bypass have not shown significant differences in weight loss [ 5 ]. Despite excellent weight loss, a percentage of patients still fail to lose 50% excess weight loss or reach a BMI of less than 35 kg/m 2 .…”

Background Historically, Roux-en-Y gastric bypass (RYGB) has been considered the gold standard of bariatric surgery (BS). This procedure acts as a mixed restrictive and malabsorptive operation. Methods This retrospective cohort study included 410 morbidly obese patients (BMI > 40 kg/m2 or BMI > 35 kg/m2 along with at least one major comorbidity) who underwent primary laparoscopic RYGB surgery from 2009 to 2015 by a single surgery team. The patients were 18 years and older with at least 12 months of follow-up. Total weight loss (%TWL) and comorbidity resolution were compared in short-term (12 months) and mid-term (12–60 months) follow-ups. The primary and secondary outcomes were evaluating the effect of Roux-en-Y on weight loss and control of comorbidities, respectively. Results The mean ± SD age, weight, and BMI at surgery were 40.1 ± 10.58 years, 123.32 ± 19.88 kg, and 45.78 ± 5.54 kg/m2, respectively, and 329 (80%) were female, and 62 (15%) had T2DM. %TWL was significantly higher in T2DM patients 9 months postoperatively and after that. Patients with lower BMI (< 50 kg/m2) at surgery and non-diabetic patients had a significantly lower %TWL over a short- and long-term follow-up (P < 0.001). Conclusions BS remains the most efficacious and durable weight loss treatment. However, a proportion of patients will experience insufficient weight loss following BS.
