RESUMO
BACKGROUND: Entrapment of an orally introduced tube by stapling/stitching is an intra-operative complication of bariatric surgery with grave consequences. Incidence is unknown. No prevention/management strategy is available. A systematic review was performed to assess the absolute reported observed risk and incidence. Additionally, data on 3 cases during our entire sleeve gastrectomy (SG) experience is evaluated. METHODS: Literature is reviewed using PubMed/Web of science data-bases. Data was recorded prospectively. Videos of orally introduced tube staplings were re-watched, presentation/recognition/management were re-evaluated. A protocol ensuring the removal of the small caliber orogastric tube (OGT) by the surgeons direct inspection was introduced after the 3rd entrapment. RESULTS: Review revealed OGT as the most commonly entrapped tube following temperature probe and bougie. SG/stapling were the most common causative operation/reason, respectively. Leak rates over 20%, conversion, early-late re-operations and mortality were reported. During our 948 consecutive SGs, 3 OGT entrapments (0.32%), third one with double stapling, occurred. All were recognized/managed intraoperatively by freeing the entrapped-end of the OGT from the sleeve part of the staple-line. In doubly stapled case, second transected end could only be recognized when routine reinforcement suturing come in proximity. Defects were continuously stitched with barbed suture. No morbidity occurred. One-year excess-weight-loss was 82%. A pre-protocol incidence of 0.56% (n: 3/534) dropped to nil in the remaining 414. CONCLUSION: Iatrogenic stapling of the OGT during SG is rare, but morbid. It must be avoided by a strict protocol. Upon occurrence/recognition, stapling must immediately stop until the "entirety" of the tube, including the "specimen-part", is retrieved, to avoid double entrapment.

Limited data exist comparing staples and sutures for closing scalp wounds during Mohs micrographic surgery (MMS). We surveyed practicing Mohs surgeons who were members of the American College of Mohs Surgery (ACMS) on their scalp wound closure preferences as well as the clinical and economic variables that impact their decisions. Comparisons were made between current practice habits, preferences, and provider demographics. Sixty-eight ACMS fellowship-trained Mohs surgeons completed the survey. Overall, scalp wounds during MMS were most frequently closed using staples.

BACKGROUND: Staples closure technology has been widely used in total knee arthroplasty (TKA) and achieved good results. In recent years, a new type of material called skin closure tape (SCT) has been applied to TKA which also showed good treatment results. However, since it is still not clear yet which one is better, this paper collects literatures for statistical analysis so as to provide evidence for the use of SCT in TKA. METHODS: The comparative study on effects between SCT and staples is reviewed after the primary release of TKA in PubMed, the Cochrane library, and the EMBASE database up to March 2019. The two researchers independently screened the literature and evaluated the quality of the literature using bias risk tools. RESULTS: A total of four studies (3330 knees) have been included in our meta-analysis. For the main point, the results show that the SCT can reduce readmission rates compared to staples (RR 0.68, 95% CI 0.49-0.95, P=0.03), with no significant difference in complications (RR 0.85, 95% CI 0.27-2.64, P=0.77). Secondly, the results suggest that although there is no significant difference in removal time between the two groups, the SCT can reduce pains, save time and costs, and have a better cosmetic effect. CONCLUSIONS: Our study indicates SCT as a closure method with fewer complications and faster speed compared with staples. Nevertheless, the cost and pain need to be further confirmed because of the small sample size included in this study.

BACKGROUND: Broncho-pleural fistula (BPF) can occur after pulmonary resections as a complication with high morbidity and mortality rates. AIM: In the present study, we analyzed the relation between the possible risk factors and the two major bronchial closure techniques for BPF after lung resections, and the management methods of BPF. MATERIALS AND METHODS: A total of 26 cases detected and managed with BPF diagnosis in our clinic between September 2005 and September 2017 were evaluated retrospectively. The cases were divided into two groups: Group 1 (n=14); bronchial closure performed manually and Group 2 (n=12) bronchial closure with stapler. We analyzed cases for age, gender, body mass index, pulmonary function tests, time to fistula, total protein/albumin level, length of hospital stay, bronchial stump distance, presence of bronchial stump coverage, and the mean survivals. RESULTS: Twenty-three of the cases were males (88.5%) with a mean age of 60.03±8.7 years (range 38-73). While BPF was detected in twenty-three (88.5%) of the cases after pneumonectomy, three (11.5%) of them were after lobectomy. There was no statistically significant correlation between the two groups in gender, age, BMI, preoperative FEV1, time to fistula, total protein/albumin level, length of hospital stay, bronchial stump distance, and presence of bronchial stump coverage (chi-square test, p>0.05). As a result of the applied Kaplan-Meier analysis, we found no statistically significant difference in the mean survival rates between the two groups (p>0.05). CONCLUSIONS: Broncho-pleural fistulas still remains a major challenge. Although there is no statistical relationship between bronchial closure techniques and possible risk factors in our study, patients should be assessed in terms of possible risk factors. The management strategy for BPF varies according to individual patients' clinical condition, the size of the fistula, and development time.

Background: Laparoscopic sleeve gastrectomy (LSG) has become the current mainstream surgical treatment for obesity. With the development of clinical practice, surgeons realized the associated severity and danger of postoperative bleeding and leakage. Surgeons constantly explore different strategies to reduce the incidence of these complications. By reviewing previous clinical articles on the staple line reinforcement (SLR) in LSG, the conclusions were inconsistent regarding effectiveness. This article aims to discuss effectiveness of oversewing the staple line in LSG. Methods: From the start date of each database to September 27, 2018, a comprehensive search of published articles in English was conducted in PubMed, Embase, Central (Cochrane) databases and Scopus databases. We extracted and analyzed the main results on postoperative bleeding, staple line leakage, hospital stay and operative time of the final included articles. This review was compliant with PRISMA guidelines. Results: Finally, we extracted and analyzed 11 randomized controlled trials (RCTs) which contain 2411 patients (1219 patients as part of the oversewing (OS) group and 1192 patients in the no-oversewing (NOS) group). In the OS group, there were 15 cases (1.23%) of postoperative bleeding, and 8 cases (0.66%) of postoperative leakage. While in the NOS group, 35 patients (2.94%) had postoperative bleeding and 21 patients (1.76%) had postoperative leakage. By comparing and analyzing the OS group and the NOS group, the risk ratio (RR) for postoperative bleeding was 0.48 (95% confidence interval [CI], 0.27-0.83 p = 0.447). In addition, the RR for postoperative leakage was 0.44 (95% CI, 0.21-0.89 p = 0.835). The standardized mean difference (SMD) for hospital stay was -0.10 (95% CI, -0.25 to 0.04 p = 0.061) and 2.26 for operative time (95%CI, 0.82-3.69 p = 0.000). Conclusion: This study suggested that oversewing the staple line during LSG has a significant clinical value: it decreased the incidence of postoperative bleeding, postoperative leakage; moreover, it also significantly prolonged the operative time and but did not change hospital stay. More high-quality and large sample RCTs are expected to get more accurate results.

Background. Surgical stapling devices are known for their reliability and convenience. A letter to health care professionals published by the US Food and Drug Administration in March 2019 highlighted the increasing number of adverse events associated with surgical staplers. Driven by a case of stapler malfunction during an elective laparoscopic sleeve gastrectomy, we performed a literature review to investigate the incidence of primary stapler malfunction. We also discuss the common types and an approach to its management. Methods. PubMed, MEDLINE, and EMBASE databases were searched for articles discussing surgical stapler malfunction. Twelve studies were selected that described the incidence and/or consequences of primary stapler malfunction. A narrative synthesis was performed. Results. From observational studies, the incidence ranged from 0.022% to 2.3%. A prospective survey reported that 86% of laparoscopic surgeons either had personal experience with or knew of surgeons who experienced stapler malfunction, implying a higher incidence. Underreporting has been an issue as manufacturers can get exemptions from public reporting. Significantly, higher malfunctions have been reported after exemptions were lifted. The most common types of stapler malfunction are stapler misfire and stapler locking. Major morbidity and mortality have been reported. Conclusion. Surgeons are increasingly reliant on technological innovations. Stapling failure occurs and it is imperative to be aware of this. Given the high volume of stapler use, a high percentage of surgeons are likely to encounter this problem in their career. It is important to have an approach to the prevention and management of this potentially catastrophic complication.

BACKGROUND: The transection of rectum and fashioning of anastomosis is a crucial step in laparoscopic total mesorectal excision (TME) and the double-stapling technique (DST) is often employed. This study aimed to evaluate the factors that were associated with difficult DST. METHOD: Cases of laparoscopic TME were retrospectively reviewed. The clinico-anatomical parameters were retrieved from a prospectively maintained database. In addition, pelvic dimensions were taken by reviewing the magnetic resonance imaging scan. The number of stapler cartridges used for intracorporeal transection of rectum was used as a surrogate for the level of difficulty of DST and its relationship with various parameters were evaluated. RESULTS: There were a total of 121 consecutive cases analyzed. The mean number of stapler cartridges used was 2.1 ± 0.7. Pelvic inlet (p = 0.002) and tumor height (p = 0.015) were predictors of the number of cartridges used, R2 = 0.366. A model was developed to predict the likelihood of transecting the rectum with two or less stapler cartridges, which included the following parameters: gender, pelvic inlet, interspinous distance, intertuberous distance, and tumor height. The predicted probability also correlated with overall operation time (p = 0.009) and anastomotic leakage (p = 0.023). CONCLUSION: The difficulty of DST was associated with patient's clinico-anatomical factors. Surgeons can consider other feasible alternatives, like transanal anastomosis, when a technically challenging DST is anticipated.

BACKGROUND: Many studies have been conducted to compare the hand-sewn and mechanical staples in esophageal cancer (EC) patients who received esophagogastric anastomosis. However, the results remain controversial. Hence, the purpose of the meta-analysis is to evaluate the impact of different anastomosis methods on the early and long-term outcomes. METHODS: We will perform a systematic electronic search of the PubMed, Embase, Cochrane Library, Web of Science for relevant articles published in English language. Pooled odds ratios will be calculated for the effect on discrete variables including anastomotic leakage, anastomotic strictures, 30-day mortality, quality of life, cardiac and pulmonary complications. The weighted mean difference was calculated for the effect size on continuous variables such as operative time and bleeding amount. We will use the software Review Manager 5.3 and STATA 14.0 to perform the meta-analysis to calculate the data synthesis. RESULTS: The review will provide a high-quality synthesis of current evidence of the impact of different anastomosis methods on postoperative course in ECs after esophagectomy. The results will be published in a peer-reviewed journal. CONCLUSION: This systematic review and meta-analysis will compare the different anastomosis methods in EC patients. The results will better offer some specific suggestions for esophagogastric anastomosis. PROSPERO REGISTRATION NUMBER: This systematic review protocol has been registered in the PROSPERO network (No. CRD 42019109523).

Objective: To evaluate patient satisfaction and patient and physician assessment of scar appearance after cesarean skin closure with suture versus staples. Methods: Women undergoing cesarean delivery (CD) at ≥23 weeks' gestation via low-transverse skin incisions at three hospitals in the CROSS Consortium were randomized to receive skin closure using subcuticular absorbable suture or nonabsorbable metal staples. The primary outcome of this substudy, patient satisfaction, was assessed by surveys at the postpartum visit using a 10-point Likert scale. Scar outcomes according to patients and trained observers were assessed at the primary research site using the Patient and Observer Scar Assessment Scale (POSAS). The POSAS is comprised of a patient-completed assessment including subjective data such as pain and itchiness, and an observer-completed assessment about cosmetic criteria. Results: Between June 2010 and August 2012, 746 women were randomized; 370 received suture and 376 received staples. Satisfaction data were available for 606 (81%). Complete patient scar assessment data were available for 577 (77%) and complete observer scar assessment data were available for 275 (57% of the 480 planned for evaluation at the primary research site). Demographic data for women in the two groups were similar. Satisfaction with the closure method was higher (superior) among women who received suture closure: median 10 (interquartile range 9, 10) versus 9 (interquartile ranges (IQR) 6, 10); p < .01. The suture group also had higher satisfaction with the scar's appearance at the postpartum visit: median nine (IQR 7, 10) versus 8 (IQR 6, 10); p = .02. Receiving one's preferred closure method was associated with higher patient satisfaction, and wound complications were associated with lower satisfaction. POSAS scores were superior (lower) in the suture group. Patient Scar Assessment Scale scores were median 15 (IQR 10, 25) for sutures versus 20 (IQR 11, 28) for staples; p < .01. Observer Scar Assessment Scale scores were median 12 (IQR 9, 15) for sutures versus 13 (IQR 9, 16) for staples; p = .01. Conclusions: Satisfaction with the closure method, satisfaction with the scar's appearance, and patient and physician assessments of scar cosmesis were all superior in those closed with suture. These results further support the use of sutures for cesarean skin closure.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has become a dominant bariatric procedure. In the past, significant leak rates prompted the search for staple line reinforcement (SLR) techniques. Previous analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database for all LSG suggested a detrimental influence of SLR on leak rates and overall morbidity. OBJECTIVE: To investigate the relationship between various SLR techniques and bougie size with 30-day outcomes. SETTING: Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program-accredited bariatric surgery hospitals. METHODS: Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 to 2016 Participant Use File data, primary LSG cases were divided into study groups based on surgical techniques. All variables were reported in the Participant Use File except leak rate and overall morbidity, which had to be derived. Multiple bivariate analyses were used to analyze the 30-day outcomes. RESULTS: A total of 198,339 primary LSG operations were included and grouped into No SLR (23.0%), SLR (54.2%), oversewn staple line (9.5%), and a combination of SLRâ¯+â¯oversewn staple line (13.3%). There were no statistical differences between study groups in mortality, overall morbidity, or leak rate. Bleeding and reoperation rates were statistically higher in the No SLR group. Bougie size was not associated with change in leak rates. CONCLUSION: Primary LSG is a safe procedure with low morbidity and mortality rates. SLR is associated with decreased rates of bleeding and reoperations but does not affect leak rates. The selection of SLR technique should be left to the surgeon's discretion with an understanding of the associated risks, benefits, and costs.

BACKGROUND: While there are various techniques to create the gastrojejunostomy during a laparoscopic Roux-en-Y gastric bypass (LRYGB), many surgeons prefer using a circular stapler. One drawback of this method, however, is the higher incidence of surgical site infections (SSIs). To investigate the effect of a dual ring wound protector on SSIs during LRYGB. METHODS: In April 2016, our bariatric surgical group implemented an intervention whereby a dual ring wound protector in conjunction with a conical EEA stapler introducer was used when creating the gastrojejunostomy. SSIs from pre- and post-intervention were compared using Fisher's exact test. Only LRYGBs performed with a circular stapler were included in our analysis. Student's t test and χ2 were used to compare pre- and post-intervention groups with respect to demographics and co-morbidities. RESULTS: Between April 2015 and January 31st, 2017, our surgeons performed 158 LRYGBs using a circular stapler for the gastrojejunostomy. There were 84 patients (53%) in the pre-intervention group and 74 (47%) in the post-intervention group. The pre- and post-intervention groups were not statistically different. The SSI rate for the pre-intervention group was 9.5% while the SSI rate was 1.35% in the post-intervention group (p = 0.0371). The use of a dual ring wound protector for LRYGBs with circular stapled gastrojejunostomy was associated with an 86% relative risk reduction in SSIs. CONCLUSION: Using a dual ring wound protector in conjunction with a conical EEA introducer for LRYGBs with circular stapled gastrojejunostomy significantly decreased SSIs.

PURPOSE: Mechanical gastro-intestinal anastomosis using stapler is a critical step in laparoscopic Roux-en-Y gastric bypass (RYGB). To date the effect of the direction of staples on anastomotic leak has not been investigated. The study aim was to investigate the impact of the direction of staples on the integrity of the gastro-jejunal anastomosis. MATERIALS AND METHODS: Eight gastro-jejunostomy (GJ) models were performed using porcine stomach and small intestine. Specimens were divided into group A where the cartridge was in the gastric lumen with the anvil in the jejunal lumen and vice versa in group B. Enterotomy was closed and gastric and jejunal ends were stapled off. Burst pressure (BP) was measured by infusion of methylene blue saline into the GJ model until leak occurred. Site of leak, BP, and total volume (TV) infused were recorded. Compliance (C) was calculated from the equation ΔTV/ΔBP. RESULTS: The BP was greater in group A compared to group B (18 mmHg (range 15-25) versus 11 mmHg (range 8-15); p = 0.045) despite similar TV between the groups 60.00 mL (range 55.00-65.00) versus 51.25 mL (range 40.00-60.00); p = 0.11). The compliance did not significantly differ between groups A and B (6.38 mL/mmHg (range 4.34-8.59) versus 5.61 mL/mmHg (range 3.93-7.21); p = 0.48). CONCLUSION: BP recorded when the stapler cartridge was introduced in the gastric lumen was higher than when it was introduced from the jejunal lumen. The lack of difference in compliance between groups suggests that the difference in BP was due to the difference in the direction of staples.

STUDY DESIGN: Retrospective review. OBJECTIVES: To identify factors associated with successful outcomes in patients treated with vertebral body stapling (VBS) for idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: The standard of care for moderate scoliosis (20°-45°) consists of observation and bracing with the goal of halting curve progression. Although several recent studies have confirmed the efficacy of bracing in altering the natural history of scoliosis, bracing is not universally effective. Recent studies have demonstrated that VBS is a safe and viable treatment for some young patients with scoliosis at risk for progression. The identification of factors associated with successful outcomes in VBS for idiopathic scoliosis would better define the population likely to benefit from VBS. METHODS: We retrospectively reviewed all patients from a single institution treated with VBS who met previously defined inclusion criteria. Successful treatment was defined as avoidance of a fusion and a final Cobb angle no more than 10° greater than the pretreatment Cobb angle. RESULTS: We identified 63 patients who met inclusion criteria. The patients underwent VBS at a mean age of 10.78 years and had a mean follow-up of 3.62 years (minimum 2 years). The mean pre-op Cobb angle for stapled thoracic curves was 29.5°. Seventy-four percent of the patients who had VBS of the thoracic curve have avoided progression and/or fusion, and the mean Cobb angle at most recent follow-up was 21.8°. The mean preoperative Cobb angle for lumbar curves was 31.1°. Eighty-two percent of the patients who had VBS of the lumbar curve have avoided progression and/or fusion, and their mean Cobb angle at follow-up was 21.6°. CONCLUSION: VBS is effective at preventing progression and fusion for moderate idiopathic scoliosis in immature patients. The complication rates are low.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) with staple line reinforcement (SLR) is a popular and safe treatment option for morbid obesity. We have developed, devised, and described our own method of stapleless laparoscopic sleeve gastrectomy, which in our limited study appeared safe, efficacious, and potentially cost-effective. METHODS: We analyzed the outcome of our modified LSG in a case series of three middle-aged women (median age 42 years old). Our main modification was sutured closure of the stomach rather than the commonly utilized technique of stapled closure. Our primary measure of success was the occurrence of post-operative leak. Secondary measures were (a) length of operation, (b) duration of inpatient stay, and (c) percentage of weight loss at 6 and 12 months post operation. RESULTS: Median operative time = 132 min (120-195 min), and median inpatient stays were 2 days. No post-operative leaks were recorded. The median excess weight loss at 6 months was 39% of initial weight loss and 57.7% at 12 months. CONCLUSIONS: Stapleless LSG has the potential to be an affordable alternative to the traditional LSG. High-powered studies and a formal cost analysis are required.

INTRODUCTION: The main drawback of laparoscopic sleeve gastrectomy (LSG) is the severity of postoperative complications. Staple line reinforcement (SLR) is strongly advocated. Recently, over-sewing has been proposed as a cost-effective and helpful method for reinforcing the staple line. The purpose of this study was to report our initial experience with LSG comparing over-sewing over the entire staple line with the upper-third staple line. MATERIALS AND METHODS: All obese patients seen at Negrar Sacro Cuore, Don Calabria Hospital were entered into our prospective database and were retrospectively evaluated. Complications (divided as major complications: leaks and bleeding; and minor complications: dysphagia, esophagitis, and reflux disease) and reoperations were recorded for all patients. Complications were graded according to the Clavien classification system. RESULTS: From February 2015 to March 2016, 30 patients underwent LSG. Patients were divided in two groups according to over-sewing: Group A-over-sewing over the entire staple line; and Group B upper-third over-sewing. Mean total operative time was longer in Group A-90 minutes-compared with 85 minutes in Group B. In regard to minor complications, we reported one esophagitis and two cases of dysphagia in Group B and one dysphagia in Group A. Gastroesophageal reflux was higher in Group B than in Group A (3 vs. 1, p=0.149). Three major complications were observed (10%): two bleeding and one hematoma in Group B and no major complications occurred in Group A. All major complications were conservatively treated. No leaks were reported in both groups. No mortality was observed. CONCLUSIONS: Over-sewing of the staple line was associated with fewer leaks but no conclusions can be drawn regarding the effects of over-sewing on staple line bleedings. Before standardizing surgical techniques further, trials are necessary to improve our knowledge about over-sewing in LSG.

BACKGROUND: The degree, prevalence, and risk factors linked to sleeve gastrectomy (SG) postoperative hemorrhage (POH) have not been fully defined. METHODS: An analysis was conducted on a prospectively collected database of 394 consecutive primary SGs performed in a single practice from January 2014 to December 2015. END POINTS: (1) acute POH, defined by red blood cell (RBC) transfusion and/or re-exploration; (2) subclinical POH, defined by postoperative hemoglobin drop (HgbD) >one standard deviation above mean. Variables tested included three surgical techniques: normal stapling (n = 137), "tight" stapling, (n = 142) and oversewing, (n = 115); age; gender; body mass index (BMI); co-morbidities; and elevated postoperative systolic blood pressure. RESULTS: Acute POH occurred in 11/394 patients (2.8%) and subclinical POH (HgbD > 2.2 g/dL) was detected in 27/312 (7.7%) of patients with available HgbD data. Acute POH patients had a mean HgbD of 5.43 ± 1.40 g/dl (p < 0.001) reflecting approximately 38.6% ± 10.0% of total blood volume. No difference in prevalence of POH was observed for the different surgical techniques. Compared with non-bleeders (n = 312), acute and subclinical POH patients (n = 38) had 52.6 vs. 27.2% prevalence type-2 diabetes (T2D) and 60.5 vs. 40.1% prevalence of dyslipidemia and higher mean preoperative hemoglobin 14.3 ± 11 vs.13.5 ± 1.2 (p < 0.05 for all). On regression analysis, only T2D (OR 2.6; 95% CI 1.2-5.6) and higher level of preoperative hemoglobin (OR 1.7; 95% CI 1.3-2.4) were independent risk factors for POH. CONCLUSION: In this study, acute and subclinical POH were primarily linked to T2D and not to surgical techniques. Special consideration is recommended for patients with T2D undergoing SG.

BACKGROUND: Anastomotic leakage is one of the most serious complications after rectal cancer surgery. METHOD: A prospective multicenter interventional study to assess a newly described technique of creating the colorectal and coloanal anastomosis. The primary outcome was to access the safety and efficacy of this technique in the reduction of anastomotic leak. RESULT: Fifty-three patients with rectal cancer who underwent low or ultra-low anterior resection were included in the study. There were 35 males and 18 females, with a median age of 68 years (range = 49-89 years). The median tumor distance from the anal verge was 8 cm (range = 4-12 cm), and the median body mass index was 24 kg/m2 (range = 20-35 kg/m2). Thirty patients underwent open, 16 laparoscopic, and 7 robotic surgeries. Multiple firing (2-charges) was required in 30 patients to obtain a complete rectal division. Forty-five patients had colorectal anastomosis, and 8 patients had coloanal anastomosis. The protective ileostomy was created in 40 patients at the time of initial surgery. There was no mortality in the first 30 days postoperatively, and only 10 (19%) patients developed complications. There were 3 anastomotic leakages (6%); 2 of them were subclinical with ileostomy created at initial operation and both were treated conservatively with transanal drainage and intravenous antibiotics. One patient required reoperation and ileostomy. The median length of hospital stay was 10 days (range = 4-20 days). CONCLUSION: Our technique is a safe and efficient method of creation of colorectal anastomosis. It is also a universal method that can be used in open, laparoscopic, and robotic surgeries.

BACKGROUND: Omega-loop gastric bypass (OLGB) may be associated with severe complications, including anastomotic leak, refractory ulcer or stenosis, undernutrition, and disabling digestive disorders (chronic diarrhea, steatorrhea, bile reflux, and vomiting). OLGB conversion to Roux-en-Y gastric bypass (RYGB) was suggested to treat these complications. OBJECTIVES: To evaluate the efficacy and risk of severe complications after OLGB conversion to RYGB. SETTING: University hospital. METHODS: Retrospective analysis between October 2011 and June 2016. RESULTS: Seventeen patients underwent OLGB conversion to RYGB. Fourteen patients (82%) presented at least 1 disabling digestive disorder. Before conversion, 10 patients (58.8%) received nutritional support for undernutrition. There was no postoperative mortality. Seven patients (41.1%) developed major adverse events (<90 d). At conversion, the average weight, body mass index, and percent of excess weight loss for the population without undernutrition (n = 7) were 103.7±24 kg, 38.7±6.8 kg/m², and 37%±33%, respectively. These values were 85±18.3 kg, 30.6±4.7 kg/m², and 73.3%±21.5%, respectively, at 2 years. In patients with undernutrition (n = 10), the average weight, body mass index, and percent of excess weight loss were 52.2±16.5 kg, 18.7±5.9 kg/m², and 149.3%±46.5%, respectively, before nutritional support and 58.9±14.7 kg, 21.1±5.2 kg/m², and 132.7%±39.1%, respectively, at revisional surgery. At 2 years the values were 71±5.6 kg, 24.3±2.2 kg/m², and 104.6%±15.2%, respectively. The patients experienced significant improvements in hypoalbuminemia, anemia, and vitamin/trace element deficiencies. The disabling digestive disorders resolved in 85% of patients. CONCLUSION: The conversion of OLGB to RYGB for severe complications allows for weight correction in patients with undernutrition, reduces disabling digestive disorders, and improves the nutritional status of patients. However, the conversion is associated with high morbidity.

BACKGROUND: Staple line leak after laparoscopic sleeve gastrectomy (LSG) still represents the most feared complication. The purpose of this study was to investigate whether there are factors that increase the risk for a leakage. Furthermore, we aimed to analyze the impact of a leak on weight change and resolution of comorbidities. METHODS: Since 2005, data from obese patients that undergo bariatric procedures in Germany are prospectively registered. For the current analysis, all adult subjects that had undergone primary LSG from 2005 to 2014 were considered. RESULTS: Overall, 241/15,756 (1.53%) patients experienced a leak. The occurrence of a leakage resulted in a significant increase of the mortality rate (3.7 vs. 0.2%; p < 0.01). Percent excess weight loss did not differ between leak and non-leak patients, both, at 12 (64.2 vs. 60.9%; p = 1.0) and 24 months (68.5 vs. 64.0%, p = 0.86). Similarly, no significant difference was observed for resolution rate of all comorbid conditions. Matched pair analysis confirmed these findings. Multivariable analysis identified operation time, conversion, intraoperative complications, and hypertension and degenerative joint disease as risk factors for a leak. Oversewing the staple line was associated with the lowest risk. CONCLUSION: The postoperative staple line leak after primary LSG significantly increases postoperative morbidity and mortality. We found that there are patient-related factors and operative variables that predispose to leakage after LSG. However, the occurrence of a leakage does not adversely impact the weight loss and resolution of comorbidities in the mid-term.
