[Complicated gastric cancer and modern treatment approaches]. / Oslozhnennye formy raka zheludka ­ sovremennye podkhody k lecheniyu.

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.

Case Report of Overlapping Pyloric Obstruction Due to Dichlorvos Poisoning and Cholelithiasis with Choledocholithiasis.

BACKGROUND Pyloric obstruction after dichlorvos poisoning causes repeated vomiting and inability to eat. Choledocholithiasis and cholelithiasis are the common digestive diseases, with high morbidity and relapse in elderly patients. However, the complex situation of these diseases' coexistence is a clinically intractable problem, and literature on selecting optimal surgical planning is scarce. CASE REPORT A thin 79-year-old woman took dichlorvos due to family conflicts. She improved after being urgently sent to local hospital for gastric lavage and detoxification. Over the next 3 months, she presented with intermittent nausea, vomiting, epigastric pain, and mental apathy, and was readmitted. Gastroscopy showed extensive scarring in the antrum, pyloric obstruction, and gastric retention. Magnetic resonance cholangiopancreatography revealed gallstones and choledocholithiasis. Also, she presented with gastric retention, hypertension, moderate anemia, hypoproteinemia, and electrolyte disturbances. After hospitalization, conservative treatment was performed, without improving vomiting, followed by surgical treatment. Gastrojejunostomy, Braun anastomosis, and nasojejunal feeding tube placement were performed for pyloric stenosis; cholecystectomy for cholelithiasis; and choledochotomy, intraoperative choledochoscopy examination, basket stone extraction, and primary suture of common bile duct without indwelling T tube for choledocholithiasis. Patient recovered and was discharged 9 days after surgery. She was recovered well, without vomiting, at 2-month follow-up. CONCLUSIONS Gastrojejunostomy plus Braun anastomosis is effective treatment of elderly patients with pyloric obstruction formed after pesticide-induced corrosion. Careful selection of choledocholithotomy with primary suture without indwelling T tube reduced postoperative pain and accelerated recovery. This complex case of pyloric obstruction with gallbladder and bile duct stones provides useful considerations for clinical treatment.

[A Long-Term Survival Case of Gastric Cancer with Pyloric Stenosis and Peritoneum Dissemination That Received Intravenous and Intraperitoneal Paclitaxel Combined with S-1 Therapy after Bypass Surgery].

Although a 74-year-old man with gastric cancer with pyloric stenosis(cT4aN[+]M0, Stage Ⅲ)had undergone surgery, he was diagnosed with peritoneum dissemination. He received bypass surgery, and an intraperitoneal access port was implanted in his subcutaneous space. Postoperatively, he received 4 courses of SOX therapy. In treatment effect, the primary tumor showed no change, and ascites developed. Therefore, we changed the chemotherapy regimen in intravenous and intraperitoneal paclitaxel combined with S-1 therapy. After starting this regimen, the primary tumor decreased in size, and the pyloric stenosis improved. Currently, the patient is alive without recurrence for 5 years and 8 months after intravenous and intraperitoneal paclitaxel combined with S-1 therapy and receiving this treatment regularly.

[Gastric pyloric stenosis caused by submucosal hematoma in a patient with vascular type Ehlers-Danlos syndrome:a case report].

Ehlers-Danlos syndrome (EDS) is a relatively rare syndrome characterized by excessive stretching of the skin and joints and hemorrhage and increased tissue fragility due to abnormal collagen. Particularly, vascular type EDS has been associated with type III collagen-rich aorta and intestinal tract fragility, owing to which young people are at a risk of spontaneous arterial rupture, aneurysm, aortic dissection, and gastrointestinal perforation. However, there have been few reports regarding gastric submucosal hematoma caused by EDS. Herein, we presented the case of a 29-year-old man who was diagnosed with EDS during his childhood and used to attend another hospital. He visited our hospital after developing epigastralgia and vomiting. The patient presented with pyloric stenosis caused by gastric antrum submucosal hematoma as revealed via abdominal contrast-enhanced computed tomography (CT), esophagogastroduodenoscopy (EGD), and endoscopic ultrasonography. He was admitted and underwent conservative therapy in addition to fasting, drip infusion, and tube feeding. The follow-up CT and EGD revealed hematoma shrinkage, after which he was discharged as no further deterioration was observed. Thus, based on the observed EDS characteristics, an accurate diagnosis is warranted to avoid unnecessary invasive therapy.

[A Case of Advanced Gastric Cancer with Pancreatic Invasion Completely Resected after Chemotherapy].

An 80-year-old man with severe anemia was found to have a circumferential type 3 lesion with obstruction in the gastric pylorus during upper gastrointestinal endoscopy. A contrast-enhanced CT scan of the abdomen showed severe invasion of the pancreatic head, and the diagnosis was gastric cancer L, Circ, cType 3, tub2, cT4b, N(+), M0, cStage ⅣA. The patient underwent laparoscopic gastrojejunostomy for gastrointestinal transit obstruction followed by 4 courses of SOX therapy as systemic chemotherapy. After chemotherapy, the invasion to the head of the pancreas was obscured, and pyloric gastrectomy and lymph node dissection were performed. The patient was recurrence-free as of 18 months after surgery. In this case, we performed gastric jejunal bypass surgery followed by chemotherapy with oral anticancer agents to achieve the downstaging of unresectable advanced gastric cancer with pancreatic invasion and pyloric stenosis in patients with poor general condition. As a result, the patient was able to undergo distal gastrectomy, which is one of the recommended multidisciplinary treatments.

Risk Factor Analysis of Gastroparesis Syndrome in 2652 Patients with Radical Distal Gastrectomy.

OBJECTIVE: The aim of this study is to investigate the risk factors of postoperative gastroparesis syndrome (PGS) in patients with gastric cancer who underwent radical distal gastrectomy. METHODS: The clinical data of 2652 patients with gastric cancer who underwent radical distal gastrectomy in the past 10 years were retrospectively analyzed. Furthermore, the incidence of PGS was set as the dependent variable, and the risk factors for PGS were screened using univariate and multivariate logistic regression analyses. Risk factor analysis for the different digestive tract reconstruction methods was also performed. RESULTS: Univariate analysis revealed that preoperative pyloric obstruction (p = 0.001), digestive tract reconstruction (p = 0.001), jejunum nutrition tube application (p = 0.001), intraperitoneal chemotherapy drug application (p = 0.002), age (≥ 66 years or < 66 years) (p = 0.042), operative time (≥ 184.5 min or < 184.5 min) (p = 0.049), and postoperative indwelling catheter time (≥ 4.5 days or < 4.5 days) (p = 0.045) were related to PGS. Multivariate logistic regression analysis showed that preoperative pyloric obstruction (odds ratio (OR) = 2.830, p = 0.004), application of a jejunum nutrition tube (OR = 3.309, p = 0.011), intraperitoneal chemotherapy (OR = 0.482, p = 0.010), and digestive tract reconstruction were independent risk factors for PGS. CONCLUSION: This study identified risk factors associated with PGS, which could be further applied in clinical practice.

[Effect of jejunal feeding tube placement on complications after laparoscopic radical surgery in patients with incomplete pyloric obstruction by gastric antrum cancer].

Objective: To assess the effect of jejunal feeding tube placement on early complications of laparoscopic radical gastrectomy in patients with incomplete pyloric obstruction by gastric cancer. Methods: This was a retrospective cohort study. Perioperative clinical data of 151 patients with gastric antrum cancer complicated by incomplete pyloric obstruction who had undergone laparoscopic distal radical gastrectomy from May 2020 to May 2022 in the First Affiliated Hospital of Nanchang University were collected. Intraoperative jejunal feeding tubes had been inserted in 69 patients (nutrition tube group) and not in the remaining 82 patients (conventional group). There were no statistically significant differences in baseline characteristics between the two groups (all P>0.05). The operating time, intraoperative bleeding, time to first intake of solid food, time to passing first flatus, time to drainage tube removal, and postoperative hospital stay, and early postoperative complications (occurded within 30 days after surgery) were compared between the two groups. Results: Patients in both groups completed the surgery successfully and there were no deaths in the perioperative period. The operative time was longer in the nutritional tube group than in the conventional group [(209.2±4.7) minutes vs. (188.5±5.7) minutes, t=2.737, P=0.007], whereas the time to first postoperative intake of food [(2.7±0.1) days vs. (4.1±0.4) days, t=3.535, P<0.001], time to passing first flatus [(2.3±0.1) days vs. (2.8±0.1) days, t=3.999, P<0.001], time to drainage tube removal [(6.3±0.2) days vs. (6.9±0.2) days, t=2.123, P=0.035], and postoperative hospital stay [(7.8±0.2) days vs. (9.7±0.5) days, t=3.282, P=0.001] were shorter in the nutritional tube group than in the conventional group. There was no significant difference between the two groups in intraoperative bleeding [(101.1±9.0) mL vs. (111.4±8.7) mL, t=0.826, P=0.410]. The overall incidence of short-term postoperative complications was 16.6% (25/151). Postoperative complications did not differ significantly between the two groups (all P>0.05). Conclusion: It is safe and feasible to insert a jejunal feeding tube in patients with incomplete outlet obstruction by gastric antrum cancer during laparoscopic radical gastrectomy. Such tubes confer some advantages in postoperative recovery.

Aberrant pancreas adenocarcinoma in the stomach: A case report and literature review.

RATIONALE: Aberrant pancreatic tissue in the gastrointestinal tract is a relatively common finding. However, malignant transformation is extremely rare. Herein, we report a case of ectopic pancreatic ductal adenocarcinoma in the stomach wall. PATIENT CONCERNS: A 38 year old male presented with nausea, bloating, abdominal distention and weight loss for 4 months. DIAGNOSES: Endoscopy of upper gastrointestinal tract was performed twice with 2 months interval and a stenotic pyloric part was observed with a suspected submucosal lesion. It was sampled both times, however the pathology findings of the mucosal biopsies were unremarkable with no identifiable neoplastic structures. CT scan and MRI was performed and showed a thickened pyloric wall with a submucosal lesion 15 × 15 mm in diameter. Blood levels of tumor markers carcinoembrionic antigen and carbohydrate antigen 19-9 were within a normal range. INTERVENTIONS: Pyloric stenosis progressed and the patient underwent a Billroth type I distal gastric resection with D2 lymphadenectomy. Pathologic examination revealed a well differentiated ductal adenocarcinoma arising in the heterotopic pancreatic tissue (Heinrich type III). The resection margins and lymph nodes were free of tumor. The patient received adjuvant chemotherapy with 6 courses of XELOX. OUTCOMES: No disease recurrence is reported in 12 months follow-up. LESSONS: Aberrant pancreatic ductal adenocarcinoma in the stomach is a rare finding, however this pathology should be included in the differential diagnosis of gastric submucosal lesion causing pyloric stenosis.

Acute Kidney Injury with Severe Metabolic Alkalosis Caused by Habitual Vomiting in an Alcohol Abuser with Pyloric Stenosis.

A 47-year-old man was complaining of consciousness disorder. He had acute kidney injury, hypokalemia, and severe metabolic alkalosis. Initial treatment using intravenous infusion of 0.9% saline and potassium chloride improved his consciousness. It was clarified that he was a severe alcohol abuser who habitually self-vomited. We diagnosed him with volume depletion and pseudo-Bartter's syndrome due to loss of chloride by habitual vomiting. Gastrointestinal endoscopy demonstrated pyloric stenosis, which was ameliorated by Helicobacter pylori eradication therapy. We should consider volume depletion and pseudo-Bartter's syndrome as differential diagnoses when we encounter patients with acute kidney injury and severe metabolic alkalosis.

Such tubes confer some advantages in postoperative recovery.

[A Rare Case of Cronkhite-Canada Syndrome Associated with Gastric Cancer and Gastric Outlet Obstruction].

Cronkhite-Canada syndrome(CCS)is a rare non-inherited disease characterized by gastrointestinal polyposis and ectodermal abnormalities. We report a rare case of CCS associated with gastric cancer and gastric outlet obstruction with a review of the literature. A 75-year-old man was admitted because of frequent vomiting and hypoproteinemia. He was diagnosed with CCS due to typical clinical and laboratory findings including alopecia, nail atrophy, hypoproteinemia, and typical gastrointestinal polyposis. Upper endoscopic examination also pointed out a large gastric cancer mainly located in the antrum and the reversible pyloric obstruction caused by the gastric tumor. Biopsy of the tumor revealed tubular adenocarcinoma. Computed tomography demonstrated the dilated duodenum caused by packing of the gastric tumor. 1.5 months after prednisolone therapy, he underwent total gastrectomy with complete resection of the dilated duodenal bulb. Histological examination revealed gastric cancer(pap>tub1)classified into Stage ⅢC. Postoperative course was uneventful and he moved to another hospital. To our knowledge, including the present case, there were 20 reported cases of CCS associated with gastric cancer from Japan(1979-2022). Also, 7 cases of CCS associated with gastric outlet obstruction was reported.

[A Case of an Advanced Gastric Cancer Patient with Outlet Obstruction and Malnutrition Who Successfully Underwent Neoadjuvant Chemotherapy with Enteral Nutrition].

We reported a case of an advanced gastric cancer patient with gastric outlet obstruction and malnutrition who successfully underwent neoadjuvant chemotherapy with enteral feeding. The patient is a 72-year-old man. The diagnosis was advanced gastric cancer with pyloric stenosis. Both decompression and enteral nutrition was performed with a W-ED®. Chemotherapy was markedly effective and nutritional status improved. He underwent robot-assisted distal gastrectomy(D2)and Billroth Ⅱ reconstruction under good nutritional status after neoadjuvant chemotherapy with intragastric decompression and nutritional management using a W-ED® tube. W-ED® tube is a useful tool for the proper nutritional management of patients with advanced gastric cancer who have pyloric stenosis by adequate decompression and enteral feeding.

Controlled long term outcome of pyloromyotomy for pyloric stenosis: No long-term adverse effect.

PURPOSE: Pyloromyotomy for pyloric stenosis is one of the more common surgical procedures performed on infants. The long-term effects of the procedure are however unclear. The purpose of this study was to study the effects into adult life, compare them with controls and to see if there is a need for structured follow up of patients. METHODS: Of the 101 patients operated for pyloric stenosis between 1972 and 1974 at our tertiary referral center 91 could be traced. They were all invited to participate in the study and were sent validated questionnaires (PAGI-SYM, GIQLI) as well as a study-specific questionnaire examining the use of antacid drugs, incidence of gastroscopy and abdominal surgery. Sixty patients responded (66%, mean age 45 years, 46 male) and were included. Thereafter, 600 age and sex-matched controls were sent the same questionnaires. 132 responded (22%, 90 male) and were includes as controls. RESULTS: No significant differences could be found in any of the examined parameters when looking at the whole material or the male patients. Female patients had higher PAGI-SYM-scores for post prandial fullness (mean 1.11 vs 0.43, P = 0.035) and heartburn (mean 0.59 vs 0.14, P = 0.043) when compared to controls. CONCLUSIONS: The present study shows that most patients operated for pyloric stenosis during infancy experience no negative effects into adulthood. The finding in the female patient group is interesting but is unlikely to have any clinical implications. The results from this study strongly implicate that there is no need for follow up of patients into adulthood. LEVEL OF EVIDENCE: Level III.

Crack cocaine abuse as an undescribed cause of gastric outlet obstruction.

A 32-year-old male with crack-cocaine abuse for 10 years, 300 g/day. He started with epigastric abdominal pain, intensity 10/10, he went to another hospital where a perforated peptic ulcer was suspected and a laparotomy was performed, with no findings. Subsequently, he started with vomiting and weight loss, on admission, a gastric outlet obstruction (GOO) was suspected and CT scan showed a concentric duodenal growth. An upper endoscopy identified a duodenal bulb stenosis with a Forrest-III ulcer. Roux-en-Y gastrojejunal anastomosis was performed, identifying duodenal thickening, without malignancy.

Autosomal recessive cutis laxa type 1C with a homozygous LTBP4 splicing variant: a case report and update of literature.

BACKGROUND: Autosomal recessive cutis laxa (ARCL) is a heterogeneous disorder with three primary forms (ARCL 1, ARCL 2 and ARCL 3). Latent transforming growth factor beta binding protein 4 (LTBP4) anomalies cause ARCL1C and are connected to different problems in the skin and other organs. Herein, we present a seven month old Iranian boy with a clinical manifestation of ARCL1 with literature review of previous cases with attributes of ARCL1C. METHODS: Considering the craniofacial characteristics and respiratory distress of the proband, cutis laxa (CL) was expected and whole-exome sequencing (WES) was performed. RESULTS: In the proband, signs of CL were mainly located in the face, thorax, and abdomen. The prenatal investigation revealed a diaphragmatic hernia and certain uncommon signs, such as an atrial septal defect and pyloric stenosis. The WES showed a novel homozygous mutation (c.533-1G > A) in exon six of the LTBP4 gene. CONCLUSION: This report showed a new variant with uncommon clinical features, such as a stenosis atrial septal defect and pyloric stenosis, which causes ARCL1C. Unfortunately, the proband developed several heart problems and died at the age of seven months and seven days. Thus, a more in-depth evaluation is needed to clarify the different aspects of CL related to LTBP4 disorder.
