RESUMO
BACKGROUND: Postoperative pneumothorax is a well-known but relatively rare complication after laparoscopic surgery. There has been no report describing pneumothorax that persisted for a week or more after laparoscopic surgery. Herein, we report a case of bilateral pneumothorax after laparoscopic surgery, which appears to have occurred by a different mechanism than previously described. CASE PRESENTATION: A 65-year-old male, with a past history of esophagectomy and retrosternal gastric tube reconstruction 4 months earlier, underwent a robotic-assisted inguinal hernia repair. Postoperative chest x-rays revealed the development of bilateral pneumothorax, which became worse on postoperative day (POD) 1 and took more than 9 days to resolve spontaneously. We assumed that intra-abdominal gas replaced by the air after pneumoperitoneum might have migrated into thoracic cavities through an opened esophageal hiatus or along the retrosternal route. CONCLUSIONS: Laparoscopic surgery after radical esophagectomy may be associated with an increased risk of postoperative pneumothorax.
RESUMO
BACKGROUND: Local resection is the standard treatment for gastrointestinal stromal tumors (GISTs). Laparoscopic and endoscopic cooperative surgery (LECS) is a minimally invasive surgery used to resect GISTs. Herein, we report an extremely rare case of a gastric GIST that grossly vanished during LECS. CASE PRESENTATION: A 50-year-old Japanese female was referred to our hospital after an abnormality was detected during an esophagogastroduodenoscopy (EGD) at her annual health checkup. Based on EGD, endoscopic ultrasound (EUS), and computer tomography (CT) findings, the patient was diagnosed with a 50-mm submucosal tumor (SMT) with intraluminal growth on the anterior wall of the lesser curvature of the upper body of the stomach. We routinely use LECS to treat the intraluminal growth type of GISTs. During the intraoperative endoscopy, the intraluminal submucosal tumor, which was detected preoperatively, had vanished. A red-white scar was observed in the regressed tumor region. LECS was performed by resecting at a distance away from the scar tissue and closing the gastric wall with intracavitary sutures. In the evaluation from the tumor section view of the original resected specimen, a 22 × 14 × 8 mm lobular neoplasm was observed that was predominantly located in the gastric submucosa to the muscularis propia. Pathological findings confirmed the diagnosis of GIST with intermediate risk indicated by the Fletcher classification. The patient continued postoperative adjuvant chemotherapy with imatinib and no recurrence was detected over 12 months after surgery. CONCLUSION: LECS was performed on the vanished gastric GIST, providing the best surgical treatment and leading to an accurate diagnosis and optimal postoperative care.
RESUMO
BACKGROUND: Advanced gastric cancer has an unfavorable prognosis and poor curability. Immune checkpoint inhibitors, such as nivolumab, have recently emerged as a potential solution for this aggressive disease. However, there is a lack of established evidence on the clinical efficacy of these agents, particularly in the perioperative period for advanced gastric cancer patients who are unresectable, recurrent, or preoperative. Despite the limited data available, there have been rare cases of dramatic therapeutic effects. In this study, we present a successful case of nivolumab treatment along with surgery. CASE PRESENTATION: A 69-year-old female presented with pericardial discomfort and was diagnosed with advanced gastric cancer following upper gastrointestinal endoscopy. Laparoscopic distal gastrectomy with D2 lymph node dissection was performed, resulting in a final pathological diagnosis of Stage IIIA. The patient received postoperative adjuvant chemotherapy with oral S-1 therapy, but was found to have multiple liver metastases at 8 months postsurgery. Weekly paclitaxel and ramucirumab therapy was initiated, but the patient experienced adverse side effects, leading to the discontinuation of treatment. Nivolumab monotherapy was then administered for 18 cycles, resulting in a partial therapeutic response and PET-CT revealed a complete metabolic response. However, the patient developed a Grade 3 pemphigoid as an immune-related adverse event, leading to the cessation of nivolumab. The patient underwent laparoscopic partial hepatectomy. Postoperative pathology showed no residual tumor cells, indicating a complete response. At present, 25 months after surgery, the patient was alive without recurrence. CONCLUSION: In this report, we present a case of gastric cancer with liver metastatic recurrence, in which a complete pathological response was achieved with nivolumab treatment. Although determining whether surgical intervention is necessary following successful drug treatment can be challenging, PET-CT imaging may be useful in decision-making regarding surgical treatment.
RESUMO
BACKGROUND: The transorally inserted anvil (OrVil™) is frequently selected for esophagojejunostomy after laparoscopic total gastrectomy (LTG) because of its versatility. During anastomosis with OrVil™, the double stapling technique (DST) or hemi-double stapling technique (HDST) can be selected by overlapping the linear stapler and the circular stapler. However, no studies have reported the differences between the methods and their clinical significance. METHODS: A randomized controlled clinical trial with a parallel assignment and single-blind outcomes assessment analysis was conducted. Patients with gastric cancer eligible for LTG who met the selection criteria were randomized. Preoperative characteristics and perioperative and postoperative outcomes were compared between the DST and HDST. The primary endpoint was an anastomosis-related complication, and the secondary endpoints were perioperative outcomes and postoperative complications, excluding anastomosis-related complications. RESULTS: Thirty patients with gastric cancer were eligible and randomized. LTG and esophagojejunostomy were successfully performed in all patients, without conversion to laparotomy. Preoperative characteristics, excluding preoperative chemotherapy, were not significantly different between the two groups. One anastomotic leakage of Clavien-Dindo classification grade ≥ IIIa was observed in the DST, although no significant difference was found between the two groups (6.6% vs. 0%, P = 0.30). In the HDST, one case of anastomotic stricture required endoscopic balloon dilation. No significant differences were found in operative time, whereas the anastomosis time was significantly shorter in the HDST than in the DST (47.5 ± 15.8 vs. 38.2 ± 8.8 min, P = 0.028). Except for anastomosis-related complications, postoperative complications (P = 0.282) and postoperative hospital stay for the DST and HDST were not significantly different. CONCLUSIONS: No superiority was found between the DST and HDST with OrVil™ in esophagojejunostomy of LTG for gastric cancer with respect to postoperative complications, whereas the HDST may be preferable in terms of the simplicity of the surgical technique.

Although gastric juvenile polyposis (GJP) often coexists with gastric cancer, a preoperative accurate diagnosis is still difficult to obtain. A 70-year-old woman was referred for epigastralgia and anemia. Esophagogastroduodenoscopy with a conventional endoscope showed numerous gastric polyps with no cancerous findings. Magnifying endoscopy with narrow-band imaging (M-NBI) showed cancerous findings, and a target biopsy revealed adenocarcinoma. Histopathological findings after endoscopic resection confirmed a diagnosis of juvenile polyposis with intramucosal adenocarcinoma. Genetic analyses revealed a germline pathogenic variant of SMAD4. A target biopsy using M-NBI and endoscopic resection proved useful for confirming the preoperative diagnosis of coexisting cancerous lesions in GJP.

BACKGROUND: For total laparoscopic distal gastrectomies for gastric cancer, the reconstruction method is critical to the clinical outcome of the procedure. However, which reconstruction technique is optimal remains controversial. We originally reported the augmented rectangle technique (ART) as a reconstruction option for total laparoscopic Billroth I reconstructions. Still, little is known about its effect on long-term outcomes, specifically the incidence of postgastrectomy syndrome and its impact on quality of life. AIM: To analyze postgastrectomy syndrome and quality of life after ART using the Postgastrectomy Syndrome Assessment Scale-37 (PGSAS-37) questionnaire. METHODS: At Juntendo University, a total of 94 patients who underwent ART for Billroth I reconstruction with total laparoscopic distal gastrectomies for gastric cancer between July 2016 and March 2020 completed the PGSAS-37 questionnaire. Multidimensional analysis was performed, comparing those 94 ART cases from our institution (ART group) to 909 distal gastrectomy cases with a Billroth I reconstruction from other Japanese institutions who also completed the PGSAS-37 as part of a larger national database (PGSAS group). RESULTS: Patients in the ART group had significantly better total symptom scores in all the symptom subscales (i.e., esophageal reflux, abdominal pain, meal-related distress, indigestion, diarrhea, constipation, and dumping). The loss of body weight was marginally greater for those in the ART group than in the PGSAS group (-9.3% vs -7.9%, P = 0.054). The ART group scored significantly lower in their dissatisfaction of ongoing symptoms, during meals, and with daily life. CONCLUSION: ART for Billroth I reconstruction provided beneficial long-term results for postgastrectomy syndrome and quality of life in patients undergoing total laparoscopic distal gastrectomies for gastric cancer.
RESUMO
Background: Postoperative pyoderma gangrenosum (PPG) is a rare inflammatory skin disease of unknown etiology characterized by blistering and ulcerative lesions in postoperative wounds. Untreated pyoderma gangrenosum (PG) is potentially life-threatening; therefore, immediate and appropriate treatment is essential. Although PPG and surgical site infection (SSI) present similar clinical findings, they should be differentiated because of their conflicting treatment modalities. Case presentation: An 82-year-old man with comorbidities of pulmonary tuberculosis, chronic obstructive pulmonary disease, and diabetes underwent laparoscopic gastrectomy for gastric cancer. On postoperative day 6, fever exceeding 39°C, port wound redness, and pain was observed. Laboratory tests revealed severe inflammatory reactions: white blood cell, 42,800/µL and C-reactive protein, 30.2 mg/mL. The patient was diagnosed with SSI and treatment with antibiotics and drainage was started; however, his general and wound conditions also worsened. Therefore, he was diagnosed with PG because painful skin findings were exacerbated by external stimuli and no significant bacteria were detected in the culture test. Treatment with oral prednisolone was started, which significantly improved his skin and inflammatory conditions. Conclusion: We managed a rare case of PPG that occurred in a port wound after laparoscopic gastrectomy. If atypical clinical findings of postoperative SSI are observed, general surgeons should recognize and consider PPG as a differential diagnosis.
RESUMO
BACKGROUND: Levodopa-carbidopa intestinal gel (LCIG) treatment, a unique drug delivery system for patients with advanced Parkinson's disease (PD), is covered by health insurance in Japan since September 2016. Various LCIG procedure/device-associated adverse events (AEs) have been reported; however, reports on their treatment have been limited. This is the first multicenter study to clarify the frequency and timing of device-related AEs. METHODS: Between September 2016 and December 2018, 104 patients introduced to the LCIG treatment for advanced PD in 11 hospitals were included. The patients' characteristics, AEs incidence, AEs time, and tube exchange time were investigated. RESULTS: The median follow-up period was 21.5 months. Minor AE cases were 29.4%, whereas major AE cases were 43.1%. Majority of major AEs (n = 55, 94.8%) were managed with endoscopic treatment, such as tube exchange. Few severe AEs required surgical treatment (n =3, 5.2%). The mean (range) exposure to percutaneous endoscopic gastrojejunostomy (PEG-J) was 14.7 (0-33) months. One year after the LCIG treatment introduction, 55 patients (54.0%) retained the original PEG-J tube. The mean PEG-J tube exchange time was 10.8 ± 7.0 months in all patients, 11.6 ± 4.7 and 10.5 ± 7.7 months in patients with scheduled exchange and who underwent exchange due to AEs, respectively. CONCLUSIONS: Some device-related AEs occurred during the LCIG treatment; however, only few were serious, most of which could be treated with simple procedures or tube replacement with endoscopy. Therefore, the LCIG treatment is feasible and safe and is a unique treatment option for PD, requiring endoscopists' understanding and cooperation.

BACKGROUND: Laparoscopic distal gastrectomy (LDG) for gastric cancer has been progressed and popular in Japan, since it was first described in 1994. Several reconstruction methods can be adopted according to remnant stomach size, and balance of pros and cons. Roux-en-Y (R-Y) reconstruction is a one of standard options after LDG. Its complications include Petersen's hernia and Roux stasis syndrome. Here we report our ingenious attempt, fixation of Roux limb and duodenal stump, for decreasing the development of Petersen's hernia and Roux stasis syndrome. AIM: To develop a method to decrease the development of Petersen's hernia and Roux stasis syndrome. METHODS: We performed ante-colic R-Y reconstruction after LDG. After R-Y reconstruction, we fixed Roux limb onto the duodenal stump in a smooth radian. Via this small improvement in Roux limb, Roux limb was placed to the right of the ligament of Treitz. This not only changed the anatomy of the Petersen's defect, but it also kept a fluent direction of gastrointestinal anastomosis and avoided a cross-angle after jejunojejunostomy. 31 patients with gastric cancer was performed this technique after R-Y reconstruction. Clinical parameters including clinicopathologic characteristics, perioperative outcomes, postoperative complication and follow-up data were evaluated. RESULTS: The operative time was (308.0 ± 84.6 min). This improvement method took about 10 min. Two (6.5%) patients experienced pneumonia and pancreatitis, respectively. No patient required reoperation or readmission. All patients were followed up for at least 3 year, and none of the patients developed postoperative complications related to internal hernia or Roux stasis syndrome. CONCLUSION: This 10 min technique is a very effective method to decrease the development of Petersen's hernia and Roux stasis syndrome in patients who undergo LDG.
RESUMO
BACKGROUND: Total laparoscopic distal gastrectomy (TLDG) is increasing due to some advantages over open surgery, which has generated interest in gastrointestinal surgeons. However, TLDG is technically demanding especially for lymphadenectomy and gastrointestinal reconstruction. During the course of training, trainee surgeons have less chances to perform open gastrectomy compared with that of senior surgeons. AIM: To evaluate an appropriate, efficient and safe laparoscopic training procedures suitable for trainee surgeons. METHODS: Ninety-two consecutive patients with gastric cancer who underwent TLDG plus Billroth I reconstruction using an augmented rectangle technique and involving trainees were reviewed. The trainees were taught a laparoscopic view of surgical anatomy, standard operative procedures and practiced essential laparoscopic skills. The TLDG procedure was divided into regional lymph node dissections and gastrointestinal reconstruction for analyzing trainee skills. Early surgical outcomes were compared between trainees and trainers to clarify the feasibility and safety of TLDG performed by trainees. Learning curves were used to assess the utility of our training system. RESULTS: Five trainees performed a total of 52 TLDGs (56.5%), while 40 TLDGs were conducted by two trainers (43.5%). Except for depth of invasion and pathologic stage, there were no differences in clinicopathological characteristics. Trainers performed more D2 gastrectomies than trainees. The total operation time was significantly longer in the trainee group. The time spent during the lesser curvature lymph node dissection and the Billroth I reconstruction were similar between the two groups. No difference was found in postoperative complications between the two groups. The learning curve of the trainees plateaued after five TLDG cases. CONCLUSION: Preparing trainees with a laparoscopic view of surgical anatomy, standard operative procedures and practice in essential laparoscopic skills enabled trainees to perform TLDG safely and feasibly.

BACKGROUND: The rapid expansion of laparoscopic gastrectomy (LG) for gastric cancer has generated interest among surgeons. The adequate dissemination of correct information about such advanced laparoscopic surgery can certainly be useful for surgeons and trainees. Online video resources such as YouTube are frequently used for education. This study aimed to evaluate the quality, utility, and completeness of LG videos for gastric cancer on the video website YouTube. METHODS: The terms "laparoscopic gastrectomy" and "gastric cancer" were searched on YouTube on August 16, 2019. The first 100 videos in three sorting categories (website's default setting, view count, and length of duration) were checked by two experienced surgeons. The popularity was evaluated with the video power index (VPI). The reliability was measured using the Journal of American Medical Association (JAMA) benchmark criteria. The educational value and completeness were evaluated with a checklist developed by the researchers. RESULTS: A total of 102 videos were analyzed. Laparoscopic distal gastrectomy (LDG) and laparoscopic total gastrectomy were the most frequently recorded techniques. Lymph node (LN) dissection was the most frequently covered topic (89.2%), followed in descending order by GI reconstruction (87.3%). The mean VPI, JAMA benchmark score and completeness score of all videos were 2.63, 1.94 and 8.53, respectively. The types of sources were as follows: private users, 73 (71.6%); academic institutions, 20 (19.6%); and others, 9 (8%). A total of 97 videos with an identifiable primary surgeon originated from eighteen different countries. CONCLUSIONS: Laparoscopic videos represented by YouTube represent a useful and appropriate educational tool. However, the quality of videos varied, and the level of information incompleteness was fairly high due to insufficient reviews. The role of private uploaders and academic institutions in surgical education cannot be overestimated. It is necessary that surgeon trainers and surgical educators critically analyze the quality of video content and exercise responsibility in directing trainee surgeons. In the current era, it is best for trainees to search for peer-reviewed content.
RESUMO
INTRODUCTION: A transorally inserted anvil has been developed to facilitate the creation of a stapled anastomosis without the need for a purse string to secure the anvil into place during laparoscopic total gastrectomy (LTG). We describe a hemi-double stapling technique and application of a transorally inserted anvil for esophagojejunostomy during LTG, and we report the results of a retrospective study in which we examined the feasibility and safety of this method. We also describe the key technical details of the method. METHODS: Our anastomotic method has four chief features: (a) the esophagus is cut at a slant, and its left cut end is cut and punched for the hemi-double stapling technique; (b) the anvil and circular stapler are connected, placing the distal jejunum in cranial traction; (c) a single layer of sutures is used to correct dog-earing and overlapping, and these points are completely closed with Lembert sutures; and (d) the jejunal limb is fixed to the duodenal stump to prevent kinking of the jejunal limb and to decrease tension on the anastomosis. RESULTS: This method has been used in 53 patients thus far. LTG with Roux-en-Y reconstruction was successful in all patients, and there was no need for conversion to open surgery. The mean operative time was 313 minutes, and the mean blood loss was 106 mL. The mean postoperative hospital stay was 18 days. There was no anastomotic leakage or stenosis. CONCLUSION: Hemi-double stapling technique with a transorally inserted anvil for LTG can be performed safely and easily and safely. It can also product good outcomes.

A 68-year-old female patient presented with advanced gastric cancer and multiple hepatic tumors. Upper GI endoscopy showed a type 3 lesion in the posterior wall of the gastric body. Abdominal computed tomography revealed multiple liver metastases, and staging laparoscopy identified peritoneal dissemination. She was diagnosed with clinical Stage â £ gastric cancer(cT3N2M1H1). She received 3 courses of combined chemotherapy containing S-1 and cisplatin. The therapeutic response was PR. We performed total gastrectomy with D2 lymph node dissection and splenectomy. Histopathological examination revealed no residual cancer cells, indicating pCR. She continued S-1 adjuvant chemotherapy and has remained free from recurrence for 18 months.

Objective: A new method of drug delivery via the small bowel, continuous infusion of levodopa-carbidopa intestinal gel (LCIG), for patients with advanced Parkinson's disease (PD) has been developed and shown to improve patients' quality of life. Levodopa is infused directly and continuously into the proximal jejunum via a percutaneous endoscopic transgastric jejunostomy (PEG-J) tube that is connected to a portable infusion pump. The aim of this study was to evaluate the safety and outcomes of our PEG-J technique performed in advance of LCIG therapy in patients with advanced PD. Material and methods: We reviewed the cases of 37 patients who underwent PEG-J for LCIG therapy at our hospital between November 2016 and May 2018. Pull-through percutaneous endoscopic gastrostomy (PEG) and gastropexy were performed in all patients. The J-tube was inserted through the PEG tube and placed beyond the ligament of Treitz endoscopically under fluoroscopic guidance. After two weeks, the gastropexy sutures were removed. Results: PEG-J with placement of the tube beyond the ligament of Treitz was successful in all 37 patients. Median procedure time was 26.4 min. Median hospital stay after the procedure was 16 days. Median follow-up with the PEG-J tube in place was 11 months. There were five procedure-related complications (13.5%) and 13 device-related complications (35.1%). There was no death related to the procedure. Conclusions: Our PEG-J technique can be performed safely in patients with advanced PD, and favorable outcomes have been achieved to date.

BACKGROUND: Billroth â (Bâ ) reconstruction and Roux-en-Y (RY) reconstruction are both commonly performed after distal gastrectomy (DG). We conducted a retrospective study to evaluate which is the better option. METHODS: Included in our study were 162 patients who, between April 2011 and October 2015, underwent DG followed by Bâ reconstruction (n = 93) or RY reconstruction (n = 69). All patients were followed up for at least 1 year. We compared perioperative outcomes, postoperative complications, gastrointestinal (GI) symptoms, endoscopic findings, and nutritional status between the 2 groups of patients. RESULTS: Patient characteristics did not differ between the 2 groups, with the exception of the incidence of gastric body tumors, which was significantly higher in the RY group (73.9% vs. 19.4%; p < 0.001). Operation time was significantly longer in the RY reconstruction group (p < 0.001). There was no significant between-group difference in the grades of GI dysfunction (p = 0.122).The endoscopically determined RGB (Residual food, Gastritis, Bile reflux)scores were significantly better in the RY reconstruction group than in the BI reconstruction group (p = 0.027, p < 0.001,p < 0.001,respectively).There was also no significant between-group difference in the change (1-year postoperative value/preoperative value) in body weight, body mass index, serum albumin concentration, or total cholesterol concentration (p = 0.484,p = 0.613,p = 0.760,p = 0.890, respectively). CONCLUSIONS: RY reconstruction appears not to be advantageous over Bâ reconstruction in terms of GI function or nutritional status 1 year after surgery. RY reconstruction does appear to be superior in terms of preventing bile reflux but takes more operation time.

BACKGROUND: Esophagogastric anastomosis performed after esophagectomy is technically complex and often the source of postoperative complications. The best technique for this anastomosis remains a matter of debate. We describe a new all-stapled side-to-side anastomosis, which we refer to as triple-stapled quadrilateral anastomosis (TRIQ), that can be performed after minimally invasive surgery, and we report results of a retrospective evaluation of postoperative outcomes among the 60 patients in whom this anastomosis has been performed thus far. METHODS: The anastomosis is created by apposition of the posterior walls of the esophagus and stomach. A linear stapler is applied to create a V-shaped posterior anastomotic wall. The anterior wall is closed in a gentle chevron-like shape with the use of 2 separate linear staplers, resulting in a wide quadrilateral anastomosis. The anastomosis is then wrapped with a greater omentum flap. RESULTS: The patient group comprised 48 men and 12 women with a mean age of 67.8 years. Neoadjuvant chemotherapy was performed in 43 of these patients. Neither the thoracoscopic or laparoscopic procedure was converted to open surgery in any patient. The median operation time was 474 min (range 680-320 min). The intraoperative blood loss volume was 104.4 mL (range 240-30 mL). There were no anastomosis-related complications above Clavien-Dindo grade II. CONCLUSIONS: TRIQ can be performed easily and safely, and good short-term outcome can be expected.

BACKGROUND: Billroth I reconstruction is a means of anastomosis that is widely performed after surgical resection for distal gastric cancer. Interest has grown in totally laparoscopic gastrectomy, and several methods for totally laparoscopic performance of Billroth I reconstruction have been reported. However, the methods are cumbersome, and postoperative complications such as twisting at the site of anastomosis and obstruction due to stenosis have arisen. We developed an augmented rectangle technique (ART) by which the anastomosis is created laparoscopically with the use of three automatic endoscopic linear staplers, and the resulting anastomotic opening is wide and less likely to become twisted or stenosed. The technical details of our ART-based Billroth I anastomosis are presented herein along with results of the procedure to date. METHODS: The technique was applied in 160 patients who underwent totally laparoscopic distal gastrectomy for gastric cancer between December 2013 and August 2017. Clinicopathological data, surgical data, and postoperative outcomes were analyzed. RESULTS: During surgery, there were no troubles associated with gastrointestinal reconstruction and there was no transition to laparotomy. There were no postoperative complications, including suture failure and stenosis, associated with the gastrointestinal reconstruction, and the average postoperative hospital stay was 12 days. CONCLUSION: Totally laparoscopic ART-based Billroth I reconstruction is both feasible and safe. We expect this technique to contribute to the spread of safe totally laparoscopic surgery for gastric cancer.
