Complicated gastric cancer and modern treatment approaches

Among all patients with gastric cancer, 40% admit to the hospitals due to cancer-related complications. The most common complications of gastric cancer are bleeding (22-80%), malignant gastric outlet obstruction (26-60%), and perforation (less than 5%). The main treatment methods for gastric cancer complicated by bleeding are various forms of endoscopic hemostasis, transarterial embolization and external beam radiotherapy. Surgical treatment is possible in case of ineffective management. However, surgical algorithm is not standardized. Malignant gastric outlet stenosis requires decompression: endoscopic stenting, palliative gastroenterostomy. Surgical treatment is also possible (gastrectomy, proximal or distal resection of the stomach). The main problem for patients with complicated gastric cancer is the lack of standardized algorithms and abundance of potential surgical techniques. The aim of our review is to systematize available data on the treatment of complicated gastric cancer and to standardize existing methods.

The Pivotal Role of Negative Pressure Wound Therapy in the Management of Enteroatmospheric Fistula: A Year-Long "Obstacle Marathon"

Background. Enteroatmospheric fistula (EAF) is an abnormal communication between the gastrointestinal tract and the atmosphere. This phenomenon is still considered one of the most significant challenges faced by general surgeons after abdominal surgery. Primary goals of managing EAF include controlling and diverting intestinal contents outside the abdominal cavity, protecting surrounding tissues from retraction, and promoting wound healing. Achieving these goals is not easy. EAF has a 40% mortality rate. Several techniques have been proposed for managing this problem, including negative pressure wound therapy. The use of bladder catheters, nipples, endoscopic stents, vascular grafts, and fistula funnel, among other options, in the management of EAF has also been described. Case Report. The patient in the current report underwent Hartmann reversal surgery. On postoperative day (POD) 5, he had an anastomotic leak with ischemia of the descending colon and the transverse colon. Resection of the ischemic colon was performed, followed by creation of a terminal ileostomy on the last ileal loop on the right side. The first small orifice of EAF appeared on POD 23, the second on POD 28, and the third on POD 45. On POD 253, the patient underwent resection of the fistulated loop, extensive vitreolysis of the entire small intestine, and mechanical jejunojejunal laterolateral anastomosis to reestablish the canalization toward the previous terminal ileostomy on the right side. Complete closure of the skin was evident on POD 358. Conclusion. There is no ideal treatment approach that is valid for all cases of EAF. Spontaneous closure of an EAF is unlikely but feasible in the setting of a single, deep lesion with limited output and when intestinal continuity is preserved.

Endoscopic Stenting Only for a Duodenal Perforation: An Alternative to Conventional Surgical Repair

ABSTRACT Perforation of the duodenum is a rare, life-threatening complication of balloon dilation of duodenal strictures, which is managed surgically. Our case is of duodenal perforation as a complication of endoscopic balloon dilation for duodenal stricture. The perforation and stenosis were successfully managed by placement of an 18 mm × 12.3 cm WallFlex fully covered stent secured by clips to prevent migration. A follow-up endoscopy with stent removal revealed no perforation and resolution of the duodenal stricture. Our case emphasizes endoscopic stenting as an alternative to conventional surgical repair for iatrogenic duodenal perforations secondary to recurring duodenal strictures.

Laparoscopic Gastrogastrostomy – An Alternative Procedure for Stenosis after Sleeve Gastrectomy

Abstract Introduction: Reflux symptoms associated with stenosis after laparoscopic sleeve gastrectomy can occur secondary to anatomical abnormality including mechanical stenosis and axial deviation, commonly occurring mid-sleeve. Treatment options include endoscopic intervention, including dilatation, stenting, myotomy, and surgical revision, with Roux-en-Y gastric bypass (RYGB) being preferred by many. In this case series, we report six patients who have undergone laparoscopic gastrogastrostomy (GG) for gastric stenosis and propose this as a possible surgical alternative for appropriately selected patients with symptomatic angularis stenosis. Patients and Methods: Medical records for six patients who underwent laparoscopic GG for treatment of persistent reflux symptoms due to angularis stenosis were reviewed. All patients were preoperatively investigated with endoscopy and abdominal three-dimensional computed tomography. Hiatal hernia and esophageal dilation were excluded. After further consultation, patients proceeded to laparoscopic GG. Results: Complete resolution of symptoms was reported in three of six patients, with Visick score 1, while the other three reported significantly improved symptoms. Postoperative body mass index remained similar to prerevision baseline. There were no postoperative complications. Conclusion: Revision to RYGB is effective for stenosis and reflux but can be challenging with the potential for long-term nutritional deficiencies and surgical complications. For patients with angularis stenosis, laparoscopic GG is a simpler revisional procedure that has shown adequate initial outcomes with no short or anticipated long-term complications in this case series. Patients with persisting symptoms could undergo subsequent gastric bypass if needed.

Endoscopic ultrasound-guided lumen-apposing metal stent with or without coaxial plastic stent for pancreatic fluid collections: a systematic review and meta-analysis comparing safety and efficacy.

Endoscopic ultrasound (EUS)-guided lumen-apposing metal stents (LAMS) are preferred for draining symptomatic large pancreatic fluid collections (PFCs). A concurrent coaxial double-pigtail plastic stent (DPPS) is proposed to reduce adverse events associated with LAMS. We aimed to perform a comparative outcome analysis of LAMS with or without DPPS for PFCs. Electronic databases from January 2005 through July 2023 were searched for studies comparing the use of LAMS with or without DPPS for PFCs. Pooled proportions were calculated using fixed (inverse variance) and random-effects (DerSimonian-Laird) models. After reviewing 1780 studies, we extracted data from 6 studies comprising 348 patients. The weighted odds of overall technical success, using LAMS plus DPPS compared to LAMS alone, were 0.53 (95% confidence interval [CI] 0.15-1.83), and the odds of clinical success were 1.10 (95%CI 0.59-2.05). The weighted odds of total adverse events with LAMS compared to LAMS plus DPPS were 2.21 (95%CI 1.37-3.59). Analysis of individual adverse events showed that the odds of stent occlusion when LAMS alone was used compared to LAMS plus DPPS was 2.36 (95%CI 1.12-4.98). The odds of bleeding were 1.84 (95%CI 0.77-4.38), and the odds of stent migration 0.95 (95%CI 0.40-2.23). EUS-guided LAMS placement is the current standard of care for managing symptomatic large PFCs. Concurrent use of coaxial DPPS can mitigate the overall adverse events observed with LAMS, while maintaining similar technical and clinical success.

Endoscopic Intervention for Anastomotic Leakage After Gastrectomy.

Anastomotic leaks and fistulas are significant complications of gastric surgery that potentially lead to increased postoperative morbidity and mortality. Surgical intervention is reserved for cases with severe symptoms or hemodynamic instability; however, surgery carries a higher risk of complications. With advancements in endoscopic treatment options, endoscopic approaches have emerged as the primary choice for managing these complications. Endoscopic clipping is a traditional method comprising 2 main categories: through-the-scope clips and over-the-scope clips. Through-the-scope clips are user friendly and adaptable to various clinical scenarios, whereas over-the-scope clips can close larger defects. Another promising approach is endoscopic stent insertion, which has shown a high success rate for leak closure, although vigilant monitoring is required to monitor stent migration. Infection control is essential in post-surgical leakage cases, and endoscopic internal drainage provides a relatively safe and noninvasive means to manage fluids, contributing to infection control and wound healing promotion. Endoscopic suturing offers full-thickness wound closure, but requires additional training and endoscopic versatility. As a promising tool, endoscopic vacuum therapy potentially surpasses stent therapy by draining inflammatory materials and closing defects. Furthermore, the use of tissue sealants, such as fibrin glue and cyanoacrylate, has been reported to be effective in selected situations. The choice of endoscopic device should be tailored to individual cases and specific patient conditions, with careful consideration of the nature of the defect. Further extensive studies involving larger patient populations are required to provide more robust evidence on the efficacy of endoscopic approach in managing post-gastric anastomotic leaks.

Double-tract reconstruction after gastrectomy for gastric cancer in patients with concomitant cardiovascular diseases

To demonstrate the capabilities and advantages of double-tract reconstruction after gastrectomy for gastric cancer and simultaneous approach in surgical treatment of patients with cardiovascular diseases and gastric cancer. We present two cases of double-tract reconstruction after gastrectomy and the gastric stump extirpation as a part of simultaneous surgical approach to patients with gastric cancer and cardiovascular diseases. A 62-year-old patient underwent simultaneous gastrectomy with double-tract reconstruction (for the first time In Russia) and aortofemoral replacement. A 61-year-old patient underwent simultaneous coronary artery bypass surgery, gastric stump extirpation with esophagogastrostomy and double-tract reconstruction. In 1 case, postoperative period was complicated by subcompensated stenosis of the right ureter due to hematoma near the right common iliac artery. This event required endoscopic stenting of the right ureter with positive effect. Both patients were discharged in 16 and 23 days after surgery. This method may be alternative to modern reconstructions. Currently, digestive tract reconstruction after gastrectomy is still important and requires further study. Simultaneous procedures in patients with cancer and cardiovascular disease became more widespread. To objectify our statements, further research is needed.

Colonic basidiobolomycosis masquerading as colon cancer with liver metastasis: A case report and review of literature

AbstractBasidiobolomycosis is a rare subcutaneous fungal infection caused by Basidiobolus ranarum. Gastrointestinal Basidiobolomycosis GIB has been increasingly reported in the literature.We present a case of a 50-year-old male patient who presented by abdominal pain and weight loss. Imaging showed a left colon mass with a small liver lesion. Provisional diagnosis of colon cancer with liver metastasis was made. Endoscopic stenting and biopsy were done, and the results of the biopsy were not conclusive. The condition was complicated by perforation, and emergency laparotomy was done. The diagnosis of colon Basidiobolomycosis was reached from surgical histopathology. Unfortunately, the patient's condition deteriorated post operatively and the patient passed away a few days after surgery.GIB is a rare fungal infection commonly presenting as a colonic neoplastic mass or inflammatory bowel disease. The endoscopy biopsy usually fails to provide definitive diagnosis. Post-operative histopathological examination with or without culture provides a definite diagnosis. Treatment of GIB includes surgical resection with appropriate antifungal therapy which revealed dramatic response in most of the cases. However, delayed diagnosis and treatment lead to dissemination of the disease which is life-threatening condition.

Interventional endoscopy in inflammatory bowel disease: a comprehensive review.

Interventional endoscopy can play a key role in the multidisciplinary management of complex inflammatory bowel disease (IBD) as an adjunct to medical and surgical therapy. The primary role of interventional IBD (IIBD) includes the treatment of Crohn's disease-related stricture, fistula, and abscess. Endoscopic balloon dilation (EBD), endoscopic stricturotomy, and placement of endoscopic stents are different forms of endoscopic stricture therapy. EBD is the most widely used therapy whereas endoscopic stricturotomy has higher long-term efficacy than EBD. Fully covered and partially covered self-expanding metal stents are useful in long and refractory strictures whereas lumen-apposing metal stents can be used in short, and anastomotic strictures. Endoscopic fistula/abscess therapy includes endoscopic fistulotomy, seton placement, endoscopic ultrasound-guided drainage of rectal/pelvic abscess, and endoscopic injection of filling agents (fistula plug/glue/stem cell). Endoscopic seton placement and fistulotomy are mainly feasible in short, superficial, single tract fistula and in those with prior surgical seton placement. Similarly, endoscopic fistulotomy is usually feasible in short, superficial, single-tract fistula. Endoscopic closure therapies like over-the-scope clips, suturing, and self-expanding metal stent should be avoided for de novo/bowel to hollow organ fistulas. Other indications include management of postoperative complications in IBD such as management of surgical leaks and complications of pouchitis in ulcerative colitis. Additional indications include endoscopic resection of ulcerative colitis-associated neoplasia (by endoscopic mucosal resection, endoscopic submucosal dissection, and endoscopic full-thickness resection), retrieval of retained capsule endoscope, and control of bleeding. IIBD therapies can potentially act as a bridge between medical and surgical therapy for properly selected IBD patients.

Endoscopic transpapillary stent placement in patients with necrotizing pancreatitis and disconnected main pancreatic duct syndrome.

Pancreatic necrosis is one of the most severe acute abdominal conditions, accounting for 15%-20% of all patients with acute pancreatitis and characterized by significant rates of postoperative complications and mortality. Patients with pancreatic necrosis, in which pathological changes are localized in the proximal pancreas and retroperitoneal space, deserve special attention. This form of the disease includes patients with disconnected main pancreatic duct (MPD) syndrome who have a difficult prognosis. The aim of the study was an improvement of treatment results in patients with necrotizing pancreatitis and signs of the dissociation of the pancreas duct system using the endoscopic transpapillary stent placement method. This study was a retrospective cohort study. There were 32 patients with acute necrotizing pancreatitis who were managed using the endoscopic transpapillary stent placement method between 2019 and 2021. Disconnected MPD syndrome was diagnosed in all 32 patients. In total, 26 patients were admitted to hospital in the first 72 h, while 6 patients were admitted after 72 h. We diagnosed the necrotizing process located in the proximal and central areas of the pancreas and peripancreatic space in all these patients ("model III"). Positive results related to transpapillary stent placement were noted in 24 (75%) patients (first cohort). A total of 20 patients from this group were admitted to hospital in the first 48 h, and 4 patients were admitted later than 72 h from the onset of disease. Moreover, 8 patients (25%; second cohort) failed to succeed in transpapillary stent placement. Complications in the first cohort occurred in 3 (12.5%) patients: dislocation of the stent into the duodenum occurred in 1 patient, and bleeding after papillosphincterotomy took place in 2 patients. Meanwhile, infected necrotized pancreatitis developed in 5 patients, and 1 patient (5%) died. Complications among the second cohort occurred in 2 (25%) patients: erosive bleeding (after debridement). Infected necrotized pancreatitis developed in 4 patients, and 2 patients (25%) died. Endoscopic transpapillary stent placement is an effective minimally invasive approach in the management of patients with necrotizing pancreatitis.

Post-ERCP cholecystitis: Incidence, characteristics, and outcomes from a prospective multicenter biliary endoscopy registry

The incidence, risk factors, and outcomes of post-ERCP cholecystitis are poorly described. We aimed to describe cases of post-ERCP cholecystitis from a prospective multicenter registry with protocolized 30-day follow-up. Patient- and procedure-related data from 7 centers were obtained. The primary outcome was post-ERCP cholecystitis, defined according to a Delphi-based criteria and causal attribution system. Risk factors and outcomes were described for all cases. Seventeen cases of post-ERCP cholecystitis were identified among 4428 patients with gallbladders undergoing ERCP between 2018 and 2023 (incidence, 0.38%; 95% confidence interval, 0.20-0.57). In ERCPs with covered metal stenting, 7 of 467 resulted in cholecystitis (incidence, 1.50%; 95% confidence interval, 0.40-2.60). Patients had symptoms at a median of 5 days (interquartile range, 5) after ERCP. Management strategies included cholecystectomy, percutaneous cholecystostomy, and endoscopic stent removal/exchange. Estimates of post-ERCP cholecystitis incidence can inform discussions around procedural risk.

Endoscopic stenting of a tumor of the rectosigmoid junction

Annotation. Obturational obstruction of the large intestine of tumor genesis belongs to acute surgical pathology and the issue of operative tactics in this case is extremely important in emergency surgery. The current trend in the treatment of complicated colorectal cancer is to carry out radical surgical interventions with the formation of primary anastomoses and compliance with basic oncological principles. However, carrying out such interventions under adverse conditions, including neglected oncological processes, the presence of severe concomitant pathologies, late hospitalization, instability and uncompensated indicators of the patient's homeostasis, leads to a high risk of developing various postoperative complications and postoperative mortality. Therefore, the use of endoscopic methods of restoring the patency of the large intestine with the help of stents is becoming widely used. Endoscopic colonic stenting is one of the modern, promising methods of treatment for patients with intestinal obstruction. It is characterized by minimal invasiveness, and a significantly lower frequency of post-surgery complications and mortality. According to the recommendations of the European Society of Gastrointestinal Endoscopy, colonic stenting is used for patients with clinical symptoms and radiological signs of tumor obstruction of the colon without signs of perforation; installation of a stent for compensation of homeostasis systems, for comprehensive preoperative preparation (if necessary, with the use of chemotherapy or X-ray therapy). The article presents the results of our own clinical observation of an endoscopic colonic stenting case as a method of symptomatic treatment of colonic obstruction in a patient with colorectal cancer and severe concomitant diseases. We analyzed the peculiarities of using colonic stents and determined the importance of mastering this method for proctologists and oncoproctologists.

Assessing the Impact of Medication and Stenting on the Quality of Life of Patients With Chronic Pancreatitis: A Prospective Study.

This research aimed to assess the effect of pharmacotherapy alone versus the combination of pharmacotherapy and endoscopic stenting on the quality of life (QoL) outcomes of chronic pancreatitis patients. Chronic pancreatitis, an inflammatory disease, often presents with persistent pain, affecting patients' quality of life. Thirty patients treated either with pharmacotherapy alone or with the addition of endoscopic stenting were analyzed. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) was used to gather data on the patients' QoL. Results showed that both treatment groups experienced improvements in global health, role functioning, fatigue, and abdominal pain scores over follow-ups. Specifically, the stenting group saw notable enhancements in global health and role functioning. The study's conclusions provide valuable insights into the potential benefits of both treatments, with stenting offering significant improvements in certain QoL parameters. However, the sample size and source limit generalizability, suggesting the need for more extensive research across diverse settings.

Is endoscopic radiofrequency ablation plus stent placement superior to stent placement alone for the treatment of malignant biliary obstruction? A systematic review and meta-analysis.

Malignant biliary obstruction (MBO) is a rare disease with a poor prognosis. Recent studies have shown that endoscopic radiofrequency ablation (ERFA) may improve survival. We conducted a systematic review and meta-analysis of the efficacy of ERFA in combination with biliary stent placement for the treatment of MBO. The study was registered in INPLASY (number 202340096). The PubMed, Cochrane Library, Web of Science, and Embase databases were searched from inception to April 2023. We selected studies comparing the efficacy of ERFA plus stent placement with stent placement alone. The primary outcomes were pooled hazard ratios (HRs) for overall survival and stent patency; the secondary outcomes were the odds ratios (ORs) for adverse events. Eleven studies (four randomized controlled trials and seven observational studies) were included in the meta-analysis. Pooled analysis showed a difference in survival time between the two groups (HR 0.65, 95% confidence interval [CI] 0.58-0.73, I2 = 40%). However, there were no differences in the duration of stent patency or the incidence of adverse events (HR 1.04, 95% CI 0.84-1.29, I2 = 46%; OR 1.41, 95% CI 1.02-1.96, I2 = 29%). ERFA has a significant survival benefit for MBO, but does not increase the risk of adverse events.

Combined endoscopic stenting and laparoscopic stent fixation for benign gastric tube stricture after esophagectomy: a case report

BackgroundThere are several options for the treatment of gastrointestinal stricture, including endoscopic stent placement and bypass surgery. However, a benign stricture is difficult to manage in a reconstructed gastric tube in the thoracic cavity owing to the technical difficulty of bypass surgery, and the possibility of stent migration.Case presentationA 78-year-old woman was admitted to our hospital for treatment for her inability to eat. She had undergone video-assisted subtotal esophagectomy with retromediastinal gastric tube reconstruction 7 years earlier. At the current admission, there was a severely dilated gastric tube in the thoracic cavity with a soft stricture immediately anterior to the spine. Conservative therapy was ineffective; therefore, endoscopic stenting was performed. However, the stent migrated to the upper side of the stricture because the stricture was mild, and the stent was not fixed in the gastric tube. Next, endoscopic stent placement followed by laparoscopic stent fixation was performed. The stent was patent and worked well, and the patient’s body weight increased. However, the stent collapsed 2 years later, with recurrence of symptoms. Stent-in-stent placement with an over-the-scope clip was performed, and the second stent was also patent and worked well.ConclusionsLaparoscopic stent fixation with endoscopic stent placement could be an effective option for patients with a benign stricture in the reconstructed gastric tube.
