Clinical Outcomes of Resectional Roux-en-Y Gastric Bypass, Compared to Sleeve Gastrectomy for Severe Obesity. Obes Surg 2023; 33:1338-1346. [PMID: 36940018 DOI: 10.1007/s11695-023-06544-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 02/28/2023] [Accepted: 03/07/2023] [Indexed: 03/21/2023]
Abstract
PURPOSE Resectional Roux-en-Y gastric bypass (RRYGB) is considered an alternative bariatric surgery in countries with a high incidence of stomach cancer because there is no excluded stomach after RRYGB. This study aimed to evaluate the efficacy and safety of RRYGB. MATERIALS AND METHODS This study included patients who underwent RRYGB and sleeve gastrectomy (SG) between 2011 and 2021. Surgical complications and metabolic and nutritional profiles were compared between the patients preoperatively and at 1, 6, and 12 months after surgery. RESULTS Twenty and seventy-six patients underwent RRYGB and SG, respectively; 7 in the SG group were lost to follow-up within 1 year. Surgical complications and baseline characteristics were comparable between two groups, except for diabetes (90.0% vs. 44.7%, p < 0.001). The decrease of HbA1c levels and incidence of reflux esophagitis were lower in the RRYGB group compared to that of SG at 1-year postoperative (-3.0% vs. -1.8%, p = 0.014; 0% vs. 26.7%, p = 0.027). The percentage of total weight loss at 1- year postoperative and incidence of dumping syndrome were comparable between the two groups. The RRYGB group had significantly lower total cholesterol level (161.9 mg/dl vs. 196.4 mg/dl, p < 0.001), but higher incidence of vitamin B12 deficiency (30.0% vs. 3.6%, p = 0.003) at 1 year postoperative compared to those of the SG group. CONCLUSIONS The RRYGB group had better postoperative outcomes for diabetes and dyslipidemia without increasing surgical complications compared to that of the SG group. Thus, RRYGB can be considered a safe and effective alternative in areas where gastric cancer is prevalent.

Safety and effectiveness of reduced-port laparoscopic sleeve gastrectomy in Asian morbidly obese patients. Sci Rep 2021; 11:23511. [PMID: 34873253 PMCID: PMC8648717 DOI: 10.1038/s41598-021-02999-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Accepted: 11/24/2021] [Indexed: 12/04/2022] Open
Abstract
Laparoscopic sleeve gastrectomy is the most frequently performed surgical intervention in patients with morbid obesity. Single-port sleeve gastrectomy (SPSG) and reduced-port sleeve gastrectomy (RPSG) are increasingly reported in the literature. This study compared the short-term outcomes of SPSG, RPSG, and conventional laparoscopic sleeve gastrectomy (CLSG). This is a single-center retrospective study of 238 morbidly obese patients, of whom 148 (62.2%) patients completed follow-up one year after surgery. Propensity score matching was performed on factors influencing the choice of approach, and fifty patients from the SPSG + RPSG and CLSG groups were successfully matched. The groups were comparable in postoperative weight loss, morbidity, pain, and resolution of obesity-related comorbidities. The percentage of excess weight loss after one year was 90.0% in the SPSG + RPSG group and 75.2% in the CLSG group (P < 0.001). Complication rates showed no significant difference. The CLSG group was superior in dyslipidemia remission (17 [37.0%] vs. 28 [63.6%], P = 0.018) in the total cohort; however, this difference disappeared after matching. Our results suggest that single-port and reduced-port approaches could be alternative choices for selected patients. As our study was limited by its retrospective nature and potential selection bias, further studies are necessary to set standardized guidelines for SPSG.

Abstract
BACKGROUND We introduced solo surgery using a laparoscopic scope holder to wide an operator's activity range and reduce instrument crowding and clashing in single incisional surgery. This study aimed to compare the surgical outcomes of solo single-incision laparoscopic surgery (SILS) and conventional multiport laparoscopic surgery (MULS) for hepatocellular carcinoma (HCC). METHODS Among 477 consecutive patients between January 2004 and December 2017, 214 patients were included. To overcome selection bias, we performed 1:1 match using propensity score matching between SILS and MULS. Baseline characteristics, operative outcomes, and postoperative complications were compared. RESULTS No significant differences in baseline characteristics and pathologic features were found between the two groups. Operation time, estimated blood loss, and postoperative major complication were not significantly different (119.0 min vs 141.6 min, p = 0.275; 200.0 mL min vs 373.3 min, p = 0.222; 0 vs 0, p = 1.000). However, postoperative hospital stay was significantly shorter in SILS (2.73 days vs 7.67 days, p = 0.005). CONCLUSIONS Solo SILS had comparable postoperative complications and feasibility in the aspect of operation time and hospital stay compared with conventional MULS for a favorable located single HCC.

Abstract
Supplemental Digital Content is available in the text Background: The incidence of uterine cesarean scar defect (niche) is high, and some patients require surgery. Single-port laparoscopy can reduce post-operative pain, and provide better cosmetic effects. This study was performed to evaluate the safety and superiority of single-port laparoscopy-assisted vaginal repair of uterine cesarean scar defect (niche) in women after cesarean section. Methods: This study included 74 patients who were diagnosed with uterine cesarean niche at the Shanghai First Maternity and Infant Hospital from January 2013 to June 2015. Thirty-seven patients underwent single-port laparoscopy-assisted vaginal surgery as the case group, and the remaining patients underwent vaginal repair surgery as the control group. We collected data from the inpatient and follow-up medical records. The clinical characteristics of these two groups were compared. The odds ratios and 95% confidential intervals were calculated for each variable by univariate and multivariate analyses. Results: Patients who underwent single-port laparoscopy-assisted vaginal repair had a significantly longer operation time (2.3 [2.0–2.7] vs. 2.0 [1.6–2.3] h, P = 0.015), shorter gas passage time (1.2 [1.0–1.5] vs. 1.7 [1.0–2.0] days, P = 0.012), shorter hospital stay (3.1 [3.0–4.0] vs. 4.5 [4.0–6.0] days, P = 0.019), and fewer complications (0 vs. 4 cases). Univariate analysis showed that depth of the niche (P = 0.021) the mild adhesiolysis score (P = 0.035) and moderate adhesiolysis score (P = 0.013) were associated with the bladder injury. Multivariate analysis showed that the moderate adhesiolysis score (P = 0.029; 95% confidence interval, 1.318–3.526) was the strongest independent predictor of bladder injury. Conclusion: This study confirmed the safety and superiority of single-port laparoscopy-assisted vaginal repair of uterine cesarean scars.

Abstract
PURPOSE Immediate breast reconstruction using laparoscopically harvested omental flap is a safe and feasible technique, providing natural contour and softness to reconstructed breasts with reduced donor-site morbidity and deformity. We report our experience using single-port laparoscopically harvested omental flap (SLOF) for immediate breast reconstruction. METHODS Between February 2015 and December 2018, 129 patients with malignant neoplasm of the breast underwent nipple-sparing mastectomy (NSM) or breast-conserving surgery (BCS) followed by immediate SLOF reconstruction at Seoul National University Bundang Hospital. We assessed their clinicopathological data, complications, and cosmetic and oncologic outcomes. Cosmetic outcomes were evaluated by three-panel assessment and the BCCT.core software program. RESULTS One hundred and six (82.2%) underwent NSM and 23 (17.8%) underwent BCS. Mean operation time was 205 (range, 134-316) minutes. Most patients had early-stage disease; 15 (11.6%) received neoadjuvant chemotherapy. Two had malignant phyllodes tumors. Cosmetic outcomes were excellent or good in 96.9% by three-panel assessment and 99.2% by the BCCT.core program with a nearly invisible donor-site scar in the umbilicus. Harvest-associated complications occurred in five (3.9%) patients, including two umbilical wound infections, one intra-abdominal infection, one umbilical hernia, and one pedicle injury. Fat necrosis (13.2%) and epigastric bulging (21.7%) were common mastectomy- or reconstruction-associated complications, but most were mild and some resolved spontaneously. Over a median 38-month follow-up, there were three local, two regional, and three systemic recurrences. CONCLUSIONS SLOF reconstruction is a feasible and safe option for immediate breast reconstruction after NSM or extensive BCS with minimal donor-site morbidity and great cosmetic outcomes.

Abstract
Objective To introduce a new surgical technique for specimen removal during laparoscopic surgery. Methods The surgical technique was described, pictured, and recorded. The surgery was performed in a tertiary hospital. Results During laparoscopic surgery, the specimen is resected from the surrounding tissues and contained in a specimen bag to prevent spillage. The edges of the bag are then pulled through the trocar site, and the specimen—protected by the bag—is removed. To facilitate the removal process and to prevent spillage, assistants will normally hold the edges of the bag during the process. To mitigate the need for assistants to hold the edges of the bag, we wrapped the pulled edges of the bag around a ring retractor, which is a plastic ring, to straighten the bag. This technique enabled the operator to remove the specimen without needing an assistant. Conclusion The technique we describe here, using a ring retractor for specimen removal, is useful when assistants are unavailable to help during laparoscopic surgery.

Abstract
Bariatric surgery is an established and effective treatment, not only to combat morbid obesity, but also to address associated metabolic comorbidities. At this time, the cutoff for bariatric or metabolic surgery in terms of body mass index (BMI) is decreasing, making it more feasible for certain individuals to consider minimally invasive surgical options. Innovations in the technique have led to the application of laparoendoscopic single-site surgery (LESS) in the field of bariatrics, which uses a single or no incision in the performance of weight-reducing surgery. To date, there is no consensus regarding patient selection though most candidates for single-port bariatric surgery are female. Some doctors suggest that single-port bariatric surgery may not be recommended in patients with BMI of more than 50 kg/m2, height of more than 180 cm, and xiphoid–umbilicus distance of more than 20 cm. Sleeve gastrectomy (SG) is now the most widely performed bariatric surgery worldwide and single-port SG (SPSG) is already established as a routine procedure in various institutions. Current evidence shows that SPSG is less painful and demonstrates higher rates of patient satisfaction regarding the wound. SPSG is feasible and is recommendable in patients who meet certain criteria. Furthermore, endoscopic treatment modalities such as intragastric balloons and endoluminal malabsorptive devices are being developed to bridge the gap between medical and surgical treatments. Nevertheless, there is still insufficient evidence to prove the superiority of LESS bariatric surgery over conventional laparoscopic surgery. Large, well-designed prospective analyses are needed to determine the criteria for selecting patients suitable to undergo LESS bariatric surgery and to predict the procedure’s role in the growth of bariatric surgery.

Abstract
BACKGROUND Revisional surgery is becoming a common and challenging practice in bariatric centers. The aim of this study was to evaluate resectional one anastomosis gastric bypass/mini gastric bypass (R-OAGB/MGB) as a revisional procedure. METHODS From January 2016 to February 2017, data on 21 consecutive patients undergoing R-OAGB/MGB for weight loss failure after primary restrictive procedures were prospectively collected and analysed. RESULTS Mean age was 39 ± 12 years (18-65), and 11 (52.3%) were women. The mean operative time was 96.4 ± 20.9 min (range, 122-80), and the mean postoperative stay was 47.8 ± 7.4 hours (range, 36-73). There were no deaths and no procedure-related complications. The mean body mass index (BMI) decreased from 42.9 ± 6.5 at the time of R-OAGB/MGB to 28.5 ± 4 at the 12-month follow-up. At that time point, the mean percentage of BMI loss (%EBL) and the mean percentage of total body weight loss (%TWL) reached 81.6 ± 0.17% and 35 ± 0.01%, respectively. CONCLUSION R-OAGB/MGB was technically straightforward, effective, and safe in this at-surgical risk population. R-OAGB/MGB should be added to the armamentarium of revisional bariatric procedures considering its technical aspects and the potential advantage on weight loss.
