RESUMO
BACKGROUND: Severe obesity impairs renal function and outcomes in kidney transplant recipients. Bariatric surgery benefits those unresponsive to medical treatments. Limited case reports exist on its efficacy and long-term prognosis for transplant candidates. Thus, this study aims to present a case in which laparoscopic sleeve gastrectomy was safely performed on a patient with severe obesity awaiting kidney transplantation. CASE PRESENTATION: This study included a dialysis patient with a body mass index of 47 kg/m2. Living-donor kidney transplantation using his younger sister as a donor was considered, but it was determined that the risk of complications during and after surgery was high. Medical treatment was first performed, but the obesity did not improve; therefore, a laparoscopic sleeve gastrectomy was performed. Although postoperative bleeding occurred, the patient was discharged from the hospital on the 14th postoperative day. Subsequently, his weight steadily decreased, and living-donor kidney transplantation was performed 13 months after laparoscopic sleeve gastrectomy was performed. Furthermore, the patient's progress after kidney transplantation was good, and he was freed from hemodialysis. CONCLUSION: Improving severe obesity before kidney transplantation is effective in improving prognosis, and bariatric surgery should be considered when medical treatment is ineffective. Future research are needed to determine the optimal time between the performance of this procedure and kidney transplantation, as well as the long-term prognosis after kidney transplantation.

AIM: Hepatic fibrosis is associated with various factors, including metabolic dysfunction-associated fatty liver disease (MAFLD), insulin resistance, and alcohol intake in patients with morbid obesity. We investigated factors directly associated with hepatic fibrosis in patients with morbid obesity using a graphical model. METHODS: We enrolled 134 consecutive patients with morbid obesity who underwent liver biopsy during sleeve gastrectomy (median age 43.5 years; MAFLD 78.4%; homeostasis model assessment of insulin resistance [HOMA-IR] 5.97; >20 g/day alcohol intake 14.2%). Patients were classified into none/mild (F0/1; n = 77) or significant/advanced fibrosis (F2/3; n = 57) groups, based on histology. Factors associated with F2/3 were analyzed using logistic regression analysis and a graphical model. RESULTS: F2/3 was observed in 42.5% of the enrolled patients. The prevalence of MAFLD and HOMA-IR values were significantly higher in the F2/3 group than in the F0/1 group; however, no significant difference in alcohol intake was observed between the two groups. On logistic regression analysis, MAFLD, but not HOMA-IR or alcohol intake, was the only independent factor associated with F2/3 (odds ratio 7.555; 95% confidence interval 2.235-25.544; p = 0.0011). The graphical model revealed that F2/3 directly interacted with MAFLD, diabetes mellitus, HOMA-IR, and low-density lipoprotein cholesterol. Among these factors, MAFLD showed the strongest interaction with F2/3. CONCLUSIONS: We determined that MAFLD was more directly associated with significant/advanced fibrosis than insulin resistance or hyperlipidemia, and alcohol intake was not directly associated with hepatic fibrosis. Metabolic dysfunction-associated fatty liver disease could be the most important factor for hepatic fibrosis in patients with morbid obesity.
RESUMO
PURPOSE: Recently, more than 10 models have been developed to predict remission of type 2 diabetes mellitus (T2DM) after metabolic surgery. The ABCD score was compared to the individualized metabolic surgery (IMS) score in terms of prediction of T2DM remission, but which of the two scoring systems is better remains controversial. METHODS: Patient data from 463 obese East Asian patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), or SG with duodenojejunal bypass (SG-DJB) as a primary operation and were followed for at least 3 years were retrospectively collected from 24 institutions. The correlation between the ABCD and IMS scoring systems and the discrimination power of the models was evaluated. The cut-off point for the IMS stage of T2DM severity was also revised to adjust the scoring system to obese East Asian patients. RESULTS: The two scoring systems were significantly well correlated. The IMS scoring system showed significant differences in T2DM remission rates between the procedures in the moderate stage, but the ABCD score showed no significant differences in each category. The discrimination power of the IMS score was comparable to that of the ABCD score at both 3 and 5 years. The revised IMS scoring system showed that SG-DJB had significantly higher T2DM remission rates in the moderate stage at 5 years than RYGB or SG. CONCLUSION: IMS score may be comparable to ABCD score to predict T2DM remission in obese East Asian patients. The revised IMS scoring system may also select candidates for SG or SG-DJB.

INTRODUCTION: Laparoscopic bariatric procedures have been performed in Japan since 2000. Laparoscopic sleeve gastrectomy (LSG) has been fully covered by National Health Insurance since 2014, and it has been increasingly performed recently. The Japan Consortium of Obesity and Metabolic Surgery conducts a nationwide survey on laparoscopic bariatric/metabolic surgery every 2 years. METHODS: The survey was sent by post or email to 97 Japanese institutions in January 2020. RESULTS: From 2000 to 2019, a total of 3669 laparoscopic bariatric/metabolic procedures were performed in 64 institutions. The most popular procedure was LSG (n = 2866), followed by LSG with duodenojejunal bypass (LSG-DJB, n = 337) and laparoscopic Roux-en-Y gastric bypass (LRYGB, n = 280). Morbidity and reoperation rates were, respectively, 29.8% and 11.8% for LRYGB, 16.8% and 2.8% for LSG, and 13.6% and 6.6% for LSG-DJB. At 5 years after the procedures, the percentage of excess weight loss was 78% for LRYGB, 66% for LSG, and 80% for LSG-DJB. CONCLUSION: This nationwide survey clearly showed that laparoscopic bariatric/metabolic surgery has been safely and effectively performed for 20 years in Japan.

The use of single-incision laparoscopic surgery is spreading widely, even in Japan, however, in the field of thoracic surgery, there exist no previous reports on the use of the Wound retractor system in single-incision thoracoscopic surgery (SITS) for mediastinal disease. We herein describe the 1st cases of video-assisted SITS of the mediastinum. Fifteen patients (5 males, 10 females) with mediastinal disease underwent SITS. The average age of the patients was 66.8( 44 ~ 90) years. The mean operative time was 186.2 minutes. Chest drainage tubes were not placed in 12 cases. Chest tubes were removed after 2.5 days in three cases. The mean postoperative hospital stay was 3.3 (2 ~ 8) days. In this report, the use of an access instrument for SITS is presented. We performed extended thymectomy using Vein harvest during surgery in patients with myasthenia gravis. The device could be handled successfully, thereby avoiding interferences between the operator and assistants. In conclusion, we believe that SITS is a feasible and safe procedure that is beneficial in selected cases.

BACKGROUND: Recent advances in endoscopic surgery have allowed laparoscopic harvesting of the omental flap with minimal deformity of the donor site. This study aimed to assess the safety and long-term complication rate for laparoscopic harvest of the omental flap (LHOF). METHODS: From April 2002 to December 2008, 96 patients underwent LHOF for immediate reconstruction after breast cancer surgery. All the patients were evaluated for operating time, length of hospital stay, and the short- and long-term complications associated with LHOF. RESULTS: The omental flap was harvested successfully in 95 of 96 cases, and the total success rate for harvesting of the omental flaps was 99% without conversion to open surgery. The median operative time for harvesting of the omental flap was approximately 1 h. Five cases of partial graft necrosis (5.2%) and two cases of vascular injury (2.1%) to the gastroepiploic artery and vein occurred, and the graft survival rate was 96.8% (93 of 95 cases). Laparoscopy-associated complications occurred in eight cases (8.3%), including one incisional hernia. CONCLUSIONS: As a safe and minimally invasive procedure, LHOF has a low incidence of short- and long-term complications. This technique can expand the indications and usefulness of the omental flap.

This report describes a case of carcinosarcoma of the duodenum. Carcinosarcoma of the duodenum is a very rare tumor. A 72-year-old man was referred to the hospital because of appetite loss. Endoscopy demonstrated an irregularly depressed lesion (type 3) in the descending portion of the duodenum opposite to the ampulla of Vater. Computed tomography showed a thickened duodenal wall and swelling of the abdominal para-aortic lymph nodes. A biopsy specimen revealed a well-differentiated adenocarcinoma. A diagnosis of duodenal carcinoma was made (cT3, cN1, cM1, cStage IV according to the TNM classification). A subtotal stomach-preserving pancreatoduodenectomy and a lymph node resection were performed. On microscopic examination, adenocarcinoma cells and spindle type sarcoma cells were observed separately in the descending portion of the duodenum opposite to the ampulla of Vater. The adenocarcinoma cells were stained with antibodies against epithelial markers keratin and carcinoembryonic antigen for immunohistochemical analyses. In contrast, the sarcoma cells were stained with antibodies to vimentin and smooth muscle actin. The pathological diagnosis of a true duodenal carcinosarcoma was thus made.

We herein describe the case of a patient with advanced gastric carcinoma combined with extra-adrenal pheochromocytoma who received a radical operation after undergoing neoadjuvant chemotherapy. A 48-year-old woman was referred to our hospital for gastric carcinoma. Computed tomography revealed an enlargement of the regional lymph nodes and a para-aortic lymph node. A diagnosis of advanced gastric carcinoma was made (cT3, cN3, cM0, cStage IV according to the Japanese Classification of Gastric Carcinoma, 2nd English edition). A reduction in size was observed in both the gastric tumor and the lymph nodes around the stomach after neoadjuvant chemotherapy. However, the paraaortic lymph node showed no remarkable change. We thus suspected this para-aortic tumor not to be a lymph node, but instead to be an extra-adrenal pheochromocytoma, because of the different response from the other regional lymph nodes. An endocrinological examination confirmed the diagnosis of extra-adrenal pheochromocytoma. A gastrectomy and a resection of the pheochromocytoma were thus performed.

BACKGROUND: Morbid obesity has become a serious health problem. We have been performing laparoscopic Roux-en-Y gastric bypass (LRYGBP) for morbid obesity since February 2002. Although LRYGBP ameliorates complications of morbid obesity, postoperative investigation of the excluded stomach is difficult. In patients with a family history of gastric cancer, resection of the bypassed stomach is sometimes added, but this requires longer operating time. There are two problems associated with LRYGBP: the high rate of gastric cancer in Japan, and how to investigate the excluded stomach. METHODS: To resolve these problems, we introduced double-balloon intestinal endoscopy. We report double-balloon endoscopy (DBE) in 4 patients. RESULTS: No problems with advancing the endoscope were encountered during observation. We used an overtube to insert the scope further in order to avoid forming redundant loops in the small intestine, and two balloons to grip the intestinal wall. Although performing DBE involves a learning curve, there were no major obstacles to passage of the scope into the esophagus, small gastric pouch, lifted jejunum, the jejunojejunal anastomosis, Y-loop, duodenum and excluded stomach. CONCLUSION: Use of the double-balloon technique makes it possible to observe the GI tract after laparoscopic LRYGBP irrespective of the length between the gastrojejunostomy and the jejunojejunostomy.

BACKGROUND: Breast cancer surgery and accompanying breast reconstruction have been diversified. We report our experience of immediate breast reconstruction using laparoscopically harvested omental flap (LHOF). METHODS: During a 44-month period, 44 immediate breast reconstructions with LHOF were performed. Patients were followed up for complications and cosmetic results. RESULTS: Forty cases of pedicled LHOF and 4 cases of free LHOF were performed after either nipple-sparing mastectomy (n = 21) or breast-conservation treatment (n = 23). Morbidity included 1 minor vascular injury (2.3%) of the LHOF, 4 wound and graft infections (9.1%), and 1 epigastric hernia (2.3%). Cosmetic results were mostly satisfactory, with a soft breast that was natural in appearance. Donor-site scars were minimal. However, in 5 patients (12.5%), omental flap size was found to be inadequate during the procedure. CONCLUSIONS: Although there is a limit of volume, LHOF is an attractive autologous flap, which makes a natural soft breast and minimal deformity of the donor site.
