RESUMO
Background: Laparoscopic bariatric surgery has been performed safely since 1991. In a persistent search for fewer and smaller scars, single port, needlescopic surgery, and other approaches have been implemented. Our goal was to analyze the safety and feasibility of using incisionless autostatic liver retraction for sleeve gastrectomy. Materials and Methods: Candidates for sleeve gastrectomy were selected, excluding those <18 and having had prior upper left quadrant surgery. Patients were randomized 1:1 to either a standard five-port technique with a fan-type liver retractor (Group A); or a four-port technique with the liver retracted using a polypropylene 1 suture passed through the right crura and retrieved at the epigastrium employing a fascial closure needle (Group B). All surgeries were performed by the same surgeon. The primary endpoint was surgery duration. Secondary outcomes were quality of surgical-field visualization, complications inherent to liver retraction, and postoperative morbidity. Results: One hundred patients were recruited (n = 50/group). The groups (both 90% females) were demographically and anthropomorphically comparable. Surgery duration was 30.4 ± 4.6 and 29.6 ± 4.7 minutes for Groups A and B, respectively (P = .41). Visualization was considered very good in 80% versus 82%, good in 16% versus 12%, and poor in 4% versus 6% (P = NS). Two patients from each group (4%) had self-limited minor bleeding from the liver attributed to the retraction technique. No 30-day morbidity was observed. Conclusions: Liver retraction using a polypropylene suture was both effective and inexpensive. Visualization and the duration of surgery were comparable to a standard liver retractor. This low-cost alternative may diminish the need for expensive instruments and reduce the number of scars without jeopardizing the safety and quality of sleeve gastrectomy.

BACKGROUND: Bariatric surgery is currently the most effective treatment for morbid obesity. Short-stay procedures have gained popularity in many surgical sub-specialties. Main benefits are early discharge, minimal loss of productivity, cost reductions, and a reduced risk of infections. Such procedures can be undertaken if the patient's safety is not jeopardized. Laparoscopic sleeve gastrectomy (LSG) has consolidated itself as a primary bariatric technique. One matter of discussion relates to its associated quick postoperative recovery, as debate rages over whether there are patient benefits to hospital stays beyond 24 h. OBJECTIVE: To assess the safety of short-stay LSG. DESIGN: Cross-sectional, descriptive, retrospective analysis of a consecutive series. METHODS: We retrospectively analyzed data collected on hospital stays, readmission rates, early and midterm major complications, and re-intervention rates on 2629 primary LSG performed between February 2007 and August 2014. RESULTS: Out of 2629 patients, 2590 (98.52 %) were discharged within the first 24 h. Thirty-nine (1.48 %) required a longer admission: 16 (0.61 %) for vomiting and 23 (0.87 %) for bleeding, 5 (0.19 %) of whom required a second procedure within those first 24 h. Four patients (0.15 %) were readmitted for dehydration between day 2 and 4. A total of 26 leaks (0.99 %) occurred between postoperative days 6 and 41. Ten intra-abdominal hematomas (0.38 %) were diagnosed after the 7th postoperative day, and seven patients (0.27 %) required percutaneous drainage. Five abdominal collections (0.19 %), unrelated to either fistulas or bleeding, were diagnosed between day 6 and 16. No major complications occurred on postoperative days 2 through 5. CONCLUSIONS: Our evidence suggests that hospital stays after LSG beyond 24 h are unnecessary in patients with no persistent vomiting or signs of bleeding or leaks; major complications generally present either within the first 24 h or after the fifth postoperative day.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has become a widely used primary bariatric surgery. As this is a restrictive procedure, calibrating bougie size is assumed to impact on both morbidity and weight loss. However, no prospective studies have confirmed this hypothesis. The objective of this trial was to compare LSG outcomes using different calibrating bougie diameters. MATERIALS AND METHODS: A randomized controlled trial: 126 patients undergoing LSG were randomized to either a 27-Fr (group A) or a 39-Fr (group B) calibrating bougie. Inclusion criteria were BMI 40-50 kg/m(2), aged 20-70 and absence of prior gastric surgery. All surgeries were performed by the same surgeon. Sample size was calculated to detect a six-point difference in percentage of excess weight loss (%EWL) at 1 year after surgery, considering an α error = 0.05 and a ß error = 0.2. The volume of resected stomach, morbidity and weight loss at 6 months and at 1 year after surgery were analyzed. RESULTS: Groups (group A n = 62, group B n = 64) were similar in BMI (44.3 vs. 43.5), aged (41.9 vs. 42.2) and female percentage (87.1 vs. 84.3 %). A 1-year follow-up was achieved in 90.1 and 87.1 %, respectively. Two major complications occurred, one leak in each group (1.6 %). The volume of resected stomach was similar (426 vs. 402 ml, P = 0.71), as well as 6 months %EWL (66.3 vs. 66.6 %; P = 0.91) and 1 year %EWL (75.6 vs. 71.3 %, P = 0.21). A 1-year %EWL higher than 50 was achieved in 96.5 % of patients in group A versus 85.2 % in group B (P = 0.11). CONCLUSIONS: The use of different bougie diameters had no impact on the volume of resected stomach, morbidity or short-term weight loss after LSG, although a trend was seen toward better weight loss with the smaller bougie. A longer-lasting follow-up will be necessary to further assess differences.
