Laparoscopic right gastroepiploic artery-sparing distal gastric tube resection with lymph node dissection for gastric tube cancer after esophagectomy: A novel surgical approach (with video).

Total resection of the gastric tube with lymphadenectomy for advanced gastric tube cancer is highly invasive and associated with severe complications. Other surgical option, partial gastrectomy or wedge resection, is insufficient if lymph node metastasis is suspected. Therefore, a technique balancing invasiveness and curability is required. First, we laparoscopically peeled off adhesions of the gastric tube, gastric mesentery (including the right gastroepiploic artery/vein), pericardial membrane, and aorta, up to the planned resection line. Subsequently, we cut the infrapyloric and right gastric arteries at their roots and dissected No. 5 and No. 6 lymph nodes. We taped and spared the right gastroepiploic artery and vein and dissected the tissues including No. 4d lymph nodes. Finally, the gastric tube was cut using a linear stapler, and the remaining gastric tube was anastomosed to the jejunum with a circular stapler. The mean operative time for the three cases treated using this intervention was 729 min. The patients were discharged on postoperative day 8 or 9 without any complications. They all remained alive and recurrence-free. This novel approach balances invasiveness and curability by leveraging the advantages of laparoscopy. The procedure was performed safely and reproducibly in three consecutive cases, providing another viable option for the treatment of gastric tube cancer.

Esophagoplasty Using a Jejunum Segment on a Vascular Pedicle

Aim: to substantiate the expediency of using a segment of the jejunum on a vascular pedicle in esophagoplasty. Materials and methods. At the National Medical Research Center of Surgery named after A.V. Vishnevsky, 12 patients underwent esophagoplasty with a combined visceral transplant, of which 9 (75.0 %) received a gastrointestinal graft and 3 (25.0 %) — a colon-jejunum one. Esophagectomy with simultaneous esophageal plastic surgery was performed in 10 (83.3 %) patients, in 4 (40 %) of them — in combination with distal gastric resection. The indication for surgery in 3 patients was cicatricial stricture of the esophagus and stenosis of the pylorus, in 2 — achalasia of the cardia of the terminal stage (in one patient — with ulcerative stenosis of the pylorus). Three more patients underwent esophagectomy due to peptic strictures: esophagogastroanastomosis (n = 1), esophagoenteroanastomosis (n = 1) and esophagus after Nissen surgery (n = 1). Cancer recurrence after proximal gastric resection and gastrectomy in 2 patients was an indication for esophagectomy. Also, 2 (16.7 %) patients were hospitalized in the National Medical Research Center of Surgery named after A.V. Vishnevsky with incomplete esophagoplasty: one person — after Dobromyslov — Torek surgery for spontaneous rupture of the esophagus, and one patient — after the unsuccessful Lewis surgery for esophageal cancer performed in other hospitals. Results. The average duration of post-operative stay was 12.7 ± 6.3 days. The postoperative period was smooth in 10 (83.3 %) patients. The failure of the cervical anastomosis was revealed in 1 (8.3 %) patient on day 5 after esophageal plastic surgery with colon-jejunum graft, which was resolved conservatively without repeated surgery. Relaparotomy was required in one patient on day 7 after surgery for bile peritonitis, the cause of which was destructive acalculous cholecystitis with perforation. All 12 patients were discharged from the clinic with full nutrition through the mouth. In the long-term period, 11 (91.7 %) patients remained under observation, 1 (9.1 %) developed an esophagogastroanastomosis stricture 1.5 months after esophageal plastic surgery, which was resolved by 4 courses of bougation during the first 9 months after surgery. No other complications were noted. Conclusion. The segment of the jejunum on the vascular pedicle, used for esophagoplasty, in the condition of a shortage of plastic material, allows not only to complete the reconstruction at once, but also to restore the natural passage of food and prevent bile reflux.

3D versus 2D laparoscopic distal gastrectomy in patients with gastric cancer: a systematic review and meta-analysis.

While laparoscopic gastrectomy is a prominent therapeutic approach for distal gastric cancer, the clinical benefits of 3D laparoscopy over 2D laparoscopy remain unclear. We aimed to compare the clinical outcomes of 3D laparoscopy and 2D laparoscopy for distal gastric cancer resection through a systematic review and meta-analysis. We searched PubMed/MEDLINE, EMBASE, and Cochrane Library databases for studies published from inception through January 2023, according to the PRISMA guidelines. The MD or RR was used to compare 3D and 2D distal gastrectomy. Random-effects meta-analysis was estimated using the inverse variance and Mantel-Haenszel method for binary outcomes and the DerSimonian-Laird estimator for continuous outcomes. After reviewing 559 studies, 6 manuscripts met the inclusion criteria. The analysis included 689 patients, with 348 (50.5%) in the 3D group and 341 (49.5%) in the 2D group. 3D laparoscopic gastrectomy reduces the operative time (WMD - 28.57min, 95% CI - 50.70 to - 6.44, p = 0.011), intraoperative blood loss (WMD - 6.69mL, 95% CI - 8.09 to - 5.29, p < 0.001), and postoperative hospital stay (WMD - 0.92days, 95% CI - 1.43 to - 0.42, p < 0.001). There were no significant differences in time to first postoperative flatus (WMD - 0.22days, 95% CI - 0.50 to 0.05, p = 0.110), postoperative complications (Relative Risk 0.56, 95% CI 0.22 to 1.41, p = 0.217), and the number of retrieved lymph nodes (WMD 1.25, 95% CI - 0.54 to 3.03, p = 0.172) between 3 and 2D laparoscopic distal gastrectomy. Our study highlights the potential advantages of 3D laparoscopy in distal gastrectomy, including shorter operative time, postoperative hospital stay, and decreased intraoperative blood loss.

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

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. A 38 year old male presented with nausea, bloating, abdominal distention and weight loss for 4 months. 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. 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. No disease recurrence is reported in 12 months follow-up. 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.

Непосредственные результаты робот-ассистированных оперативных вмешательств при раке желудка

Background: stomach cancer is the 5th most common cancer worldwide and the 3rd leading cause of cancer death. In recent years, minimally invasive (including robot-assisted) techniques have been actively implemented in surgery for urological, gynecological, and gastrointestinal cancers. Aim: to summarize the experience with robot-assisted surgical interventions for gastric cancer and to demonstrate direct surgical outcomes. Patients and Methods: in 2018–2022, 111 patients (60 men and 51 women) with gastric cancer underwent robot-assisted surgery. The mean age was 64.6±5.5 years (33–78). The mean body mass index (BMI) was 27.9±2.8 kg/m2, 39.2% of patients had obesity (BMI&gt;30 kg/m2). The tumor was located in the gastric cardia in 19 patients (17.1%), upper third of the stomach in 9 patients (8.1%), middle third of the stomach in 4 patients (3.6%), lower third of the stomach in 21 patients (18, 9%), and gastric antrum in 58 patients (52.3%). Distal subtotal gastric resection was performed in middle-third and lower-third gastric carcinomas. Gastrectomy was performed in the upper-third and gastric cardiac carcinoma. Two surgical systems, Da Vinci® Si and Da Vinci® Xi, were used for surgical interventions. Results: 79 distal subtotal gastric resections and 32 gastrectomies were performed. The median duration of distal subtotal gastric resection and gastrectomy was 210.5 min [178.8; 249.5] and 285.0 min [275.5; 303.0], respectively. The median intraoperative blood loss was 65.0 ml [10.0; 170.0], and the median number of removed lymph nodes was 29.0 [18.0; 43.0]. Histological examination revealed clear resection margins (R0) in all patients. The conversion of surgical access was required in 2 patients (1.8%). Death was reported in 1 patient (0.9%). Clavien–Dindo grade III–IV postoperative complications were detected in 7 patients (6.3%). The median in-hospital stay was 7.0 days [7.0; 10.0] after distal subtotal gastric resection and 9.0 days [9.0; 12.0] after gastrectomy. Conclusion: our findings support the global experience with robot-assisted surgical interventions for gastric cancer with minimal intra- and postoperative complications, which generally occur in elderly patients with severe comorbidities, obesity, and locally advanced cancer at baseline.

LBODP036 A Case of Euglycemic Diabetic Ketoacidosis After Distal Pancreatectomy

Abstract The patient is a 68-year-old female with a past medical history of type 2 diabetes mellitus, pancreatic mass, hypertension, hyperlipidemia, and coronary artery disease who presented to the hospital for elective surgical resection of her pancreatic mass. She underwent robotic-assisted laparoscopic distal pancreatectomy, splenectomy, and gastric wedge resection. Her hospital course was complicated by post-operative bleeding with hemoperitoneum the day after her initial surgery. She returned to the operative room for exploratory laparotomy during which the source of bleeding was identified and repaired. She was transferred to the intensive-care unit for post-operative monitoring. On the fourth day of admission, the patient became markedly acidotic. Her labs revealed a bicarbonate level of 12 mmol/L and a pH of 7.24. Her anion gap was elevated to 17. Endocrinology was consulted for suspected euglycemic diabetic ketoacidosis. Beta-hydroxybutyrate was elevated to 5.10 mmol/L (0 - 0.29 mmol/L). The patient's blood glucose was 159 mg/dL. Of note, the patient does take Empagliflozin at home. This medication has been associated with euglycemic diabetic ketoacidosis; however, she had not received this medication for five days prior to the onset of diabetic ketoacidosis. Glucosuria is expected to return to baseline after discontinuation of Empagliflozin within approximately three days. A urinalysis was checked at the time of consultation, and the patient did have a large amount of glucose in her urine which suggests that Empagliflozin was still acting to produce glucosuria. The patient was treated with intravenous insulin and fluids per the institution's protocol for the management of diabetic ketoacidosis. Her acidosis rapidly improved, and she was transitioned to subcutaneous insulin to manage her diabetes prior to discharge. This is an interesting case of euglycemic diabetic ketoacidosis due to the multifactorial precipitants: the dwindling effect of Empagliflozin five days after discontinuation, the loss pancreatic beta cell mass after distal pancreatectomy, and the stress of multiple surgeries complicated by life-threatening post-operative bleeding.

Distal gastric tube resection with preservation of the right gastroepiploic artery for gastric tube cancer: a case report

BackgroundThe incidence of gastric tube cancer is increasing because of improved survival rates in patients with esophageal cancer treated by esophagectomy. Total resection of the gastric tube is expected to be highly curative, but it is associated with a higher risk of severe postoperative complications. Herein we report a case of early gastric tube cancer that was successfully treated by distal gastric tube resection with preservation of the right gastroepiploic artery (RGEA).Case presentationAn 82-year-old man was diagnosed as having gastric tube cancer, B-12-O, Type 0-IIc, T1b, N0, M0, cStage IA (Japanese Classification of Gastric Carcinoma). Upper gastrointestinal endoscopy showed a Type 0-IIc lesion measuring 30 mm in length in the lower part of the gastric tube, and histopathological examination of biopsy specimens revealed the features of poorly differentiated adenocarcinoma. The primary lesion could not be identified by computed tomography, and there was no obvious lymph node metastasis or distant metastasis. Considering that total resection of the gastric tube would have been highly invasive and that the gastric tube cancer was at a relatively early stage, we performed distal gastric tube resection with preservation of the RGEA. The postoperative course was uneventful, and the patient was discharged on postoperative day 12. There has been no recurrence during the 17 months of follow-up.ConclusionWe successfully treated a patient with gastric tube cancer by distal gastric tube resection with preservation of the RGEA. This treatment strategy may be acceptable for patients with early gastric tube cancer without lymph node metastasis, considering the balance between the surgical invasiveness and curability of the tumor.

Late complications of biliopancreatic diversion in an older patient: a case report

BackgroundIn the mid-seventies, biliopancreatic diversion became popular as weight-loss surgery procedure. This bariatric procedure combines distal gastric resection and intestinal malabsorption, leading to greater weight loss and improvement of co-morbidities than other bariatric procedures. Nowadays, biliopancreatic diversion has become obsolete due to the high risk of nutritional complications. However, current patients with biliopancreatic diversions are aging. Consequently, geriatricians and general practitioners will encounter them more often and will be faced with the consequences of late complications.Case presentationA 74-year old female presented with weakness, recurrent falls, confusion, episodes of irresponsiveness, anorexia and weight loss. Her medical history included osteoporosis, herpes encephalitis 8 years prior and a biliopancreatic diversion (Scopinaro surgery) at age 52. Cerebral imaging showed herpes sequelae without major atrophy. Delirium was diagnosed with underlying nutritional deficiencies. Biochemical screening indicated vitamin A deficiency, vitamin E deficiency, zinc deficiency and severe hypoalbuminemia. While thiamin level and fasting blood glucose were normal. However, postprandial hyperinsulinemic hypoglycemia was observed with concomitant signs of confusion and blurred consciousness. After initiating parenteral nutrition with additional micronutrient supplementation, a marked improvement was observed in cognitive and physical functioning.ConclusionsLong-term effects of biliopancreatic diversion remain relatively underreported in older patients. However, the anatomical and physiological changes of the gastrointestinal tract can contribute to the development of metabolic and nutritional complications that may culminate in cognitive impairment, functional decline and delirium. Therefore, it is warranted to evaluate the presence of metabolic disturbances and nutritional complications in older patients after biliopancreatic diversion.

Closure of a duodenal cutaneous fistula with endoscopic negative pressure therapy using a thin open-pore film drain – an easy tool and simple method

A 57-year-old patient underwent emergency laparotomy for an acute abdomen with free intra-abdominal air caused by a perforated distal gastric ulcer. Surgical closure was performed by suture. Histological adenocarcinoma was found Therefore, revision laparotomy with distal gastric resection and Roux-en-y reconstruction was done 3 days later. At 6 days postoperatively, a discharge of biliary secretions via target drainage for duodenal stump insufficiency was seen. Surgical closure was tried in another revision laparotomy. But again biliary secretion occurred proving the persistent duodenal leakage.

Diagnosis and treatment of primary hypertrophic pyloric stenosis (HPS) in older children

Hypertrophic pyloric stenosis (HPS) is the most important cause of non-bilious vomiting during infancy and it is usually idiopathic. It is very rare in older children and adolescents, in which gastric outlet obstruction (GOO) is more typically secondary to other conditions. Gastrointestinal malformation are frequently associated with Down syndrome and some of them (especially duodenal abnormalities) can be detected quite late. In infants the standard treatment of HPS is represented by a Ramstedt pyloromyotomy, while in adults a distal gastric resection is more indicated and it is usually associated to a Billroth I or II reconstruction. We present an unusual case of a 12-year-old girl with Down syndrome, diagnosed with late-onset HPS. She came to our attention with periodic non-bilious vomiting and growth delay. She underwent multiple imaging examinations, which highlighted the presence of an HPS. Based on patient's age and the thickness of the pyloric muscle, we decided to perform a partial gastrectomy with a Roux-en-y reconstruction. Patient was discharged on the X day. She is now on follow up, gains weight and presents good conditions. HPS is rare but possible during childhood and adolescence. Diagnosis is usually performed through ultrasounds (US) and upper gastrointestinal radiological series (UGI), but sometimes further examinations are required (abdominal MRI, esophagogastroduodenoscopy). In older children since less invasive techniques are not effective, we have to consider partial gastrectomy. Based on our experience, Roux-en-y reconstruction is a valid option, associated with poor complication and good quality of life.

Reconstruction following gastrectomy

Minimally invasive surgical techniques with respect to the treatment of gastric cancer have progressed rapidly over the last few years. Especially in Asia, where the incidence of gastric cancer is ten times higher than in Europe, surgery for gastric cancer is steadily evolving, especially regarding laparoscopic and robot-assisted procedures. This review first discusses the different options for reconstruction of the gastrointestinal passage after gastrectomy, ranging from Billroth procedures to the latest developments, such as the double tract reconstruction. In particular, the possibility of function-preserving partial gastrectomy, such as proximal and distal gastric resection and the corresponding reconstruction techniques are presented. The latest studies and technical developments are presented, especially with respect to laparoscopically assisted, completely laparoscopic and robot-assisted gastrectomies.

Epidemiology and treatment of perforated duodenal ulcer in Kemerovo Region

Aim.To estimate the frequency of ulcerative bleeding, pyloric stenosis, need for pyloroplasty and the justification of vagotomy for perforated duodenal ulcer.Materials and Methods.We analyzed the surgical treatment of patients with perforated duodenal ulcer admitted to Podgorbunskiy Regional Clinical Emergency Hospital during 1999-2019.Results.In 2018, the number of surgical interventions due to perforated duodenal ulcer decreased by 56.4% in comparison with 1998. In 8.6% and 2.1% of patients, perforated duodenal ulcer was combined with pyloric stenosis and bleeding, respectively, requiring Judd pyloroplasty (diamond- shaped transverse excision) or gastroduodenotomy followed by Heineke-Mikulicz pyloroplasty (transversely closed longitudinal incision across the pylorus) and vagotomy. Distal gastric resection by Billroth’s operation II was required in 2.8% of patients. Repeated admission of patients with duodenal ulcer complications has been observed after isolated suturing of perforated duodenal ulcer.Conclusion.Over the last 20 years, the amount of surgical interventions because of perforated duodenal ulcer in Kemerovo Region decreased more than twofold. In &gt; 10% patients, pyloric stenosis and bleeding require a gastric drainage. In &gt; 8% patients, perforated duodenal ulcer is combined with pyloric stenosis; in these cases, Heineke-Mikulicz pyloroplasty may be a treatment of choice. In &gt; 2% patients, perforated duodenal ulcer is combined with ulcerative bleeding requiring excision of the ulcer and optional distal gastric resection. Pyloroplasty may be combined with vagotomy to normalise the proteolytic activity of gastric acid.

Need for pyloroplasty and vagotomy in case of perforated duodenal ulcer

Aim. Estimation of the incidence of stenosis, need for pyloroplasty and validity of vagotomy for perforated duodenal ulcer (PDU).&#x0D; Materials and methods. Twenty-year nature of surgical treatment of patients with PDC in the hospital surgery clinic is analyzed.&#x0D; Results. Over 20 years, 726 patients were operated on: 151 women (20.8%), 575 men (79.2%), mean age 39.1±6.3 years. Surgeries were performed both from laparotomic access and video laparoscopically. It is found that PDU is combined with stenosis in 8.5% and with bleeding in 1.6%, which requires Jadd excision of an ulcer on the anterior wall or gastroduodenotomy for flashing a bleeding ulcer on the posterior wall (0.7%) with subsequent Heineke — Mikulicz pyloroplasty and vagotomy. Both stem vagotomy and selective proximal were used by the method of skeletonization of lesser curvature or chemoneurolysis. Suturing with selective proximal vagotomy was performed in 567 patients, isolated suturing — in 77. B-II distal gastric resection was required in 2.1%. Repeated admission of patients with complications of a duodenal ulcer is observed after isolated suturing of PDU without surgical intervention in the mechanisms of ulcer formation.&#x0D; Conclusion. During surgical treatment of PDU are found in 79.2% of men, in 20.8% of women. There is an emerging stenosis in 8.5% of those who have PDU, which requires a gastric drainage operation. The subjects of choice may be Heineke-Mikulicz pyloroplasty or Jadd excision of an ulcer on the anterior wall. It is advisable to suture or excise an ulcer with pyloroplasty accompanied by vagotomy that normalizes the acid-proteolytic activity of gastric juice in the postoperative period and eliminates need for antisecretory drugs to prevent the recurrence of the disease.

Safety and Feasibility of No.12a Lymph Node Dissection by Portal Vein Approach in Radical Laparoscopic Gastrectomy for Gastric Cancer.

Background:Traditional laparoscopic No.12a lymph node dissection in radical gastrectomy for gastric cancer may damage the peripheral blood vessels, and is not conducive to the full exposure of the portal vein and the root ligation of the left gastric vein. We recommend a new surgical procedure, the portal vein approach, to avoid these problems.Methods:25 patients with advanced gastric cancer underwent radical laparoscopic gastrectomy and No.12a lymph node were dissected by portal vein approach, including 7 cases with total gastrectomy, 18 cases with distal gastric resection, 14 males and 11 females. Operative time, intraoperative blood loss, time to first flatus, postoperative hospital stay, number of total lymph node dissection and No.12a lymph node dissection, No.12a lymph node metastasis rate and postoperative complications were statistically observed.Results:All the patients were operated successfully and No.12a lymph node were cleaned by portal vein approach. A total of 683 lymph nodes were dissected, with the average number of lymph nodes dissection and positive lymph nodes were (27.3 ± 12.7) and (3.8 ± 5.6) respectively. The average number of No.12a lymph node dissection was (2.4 ± 1.95) and the metastasis rate of No.12a lymph node was 16% (4/25). The average operation time of radical laparoscopic distal and total gastrectomy were (239.2 ± 51.4) min and (295.1 ± 27.7) min respectively. The mean intraoperative blood loss was (134.0 ± 65.7) ml, and postoperative first anal exhaust time was (2.24 ± 0.86) d. The mean time to fluid intake was (4.2 ± 1.7) d, and postoperative hospitalization time was (9.6 ± 5.0) d. Without portal vein injure, anastomotic leakage, gastrointestinal bleeding, intestinal obstruction and other complications were observed in all patient.Conclusion:Our results show that the laparoscopic No.12a lymph node dissection by portal vein approach for gastric cancer is safe, feasible and has certain clinical application value.

Endoscopic negative pressure therapy (ENPT) for duodenal leakage - novel repair technique using open-pore film (OFD) and polyurethane-foam drainages (OPD).

Background and study aims Endoscopic negative pressure therapy (ENPT) is used to close transmural defects in the rectum and esophagus. Very few reports have described ENPT to manage duodenal defects. This study was designed to demonstrate ENPT in a population of 11 patients with transmural duodenal leakages. Patients and methods The method of ENPT was adapted for duodenal use. Open-pore polyurethane-foam or a thin, open-pore double-layered film was wrapped around the distal end of a gastroduodenal tube. First, this open-pore element was placed on the inner wound in the duodenum with endoscopy. Second, continuous negative pressure of –125 mmHg was applied with an electronic pump. Drains were changed after 2 to 7 days. Results Eleven patients were treated with duodenal leaks. Eight defects occurred after operative closure of perforated duodenal ulcers, papillectomy or stricturoplasty, one anastomotic leakage after Billroth – 1 distal gastric resection, one iatrogenic perforation in endoscopic retrograde cholangiopancreatography, and one by a surgical drain. Median duration of therapy was 11 days (range 7 – 24 days). Complete healing of defects was achieved in all patients. Conclusion ENPT is an innovative endoscopic alternative for treatment of transmural duodenal defects.

Mesh erosion after hiatal hernia repair: the tip of the iceberg?

Primary repair of large hiatal hernia is associated with a high recurrence rate, which has led to the use of mesh for crural repair. However, severe mesh-related complications, including esophageal or gastric erosion, have been observed. In the present study, we made a thorough identification of all published reports on the esophageal or gastric mesh erosion or migration after hiatal hernia repair. The incidence, site, mesh type, latent interval, consequence and treatment methods of mesh erosion were summarized and analyzed. A total of 50 cases of esophageal or gastric mesh erosion or migration after hiatal hernia repair were reported since 1998. A higher erosion rate was observed in recurrent hiatal hernia repair. The most common erosion site was esophagus (50%), followed by stomach (25%) and gastric-esophageal junction (GEJ) (23%). The most common mesh types reported in this series were PTEF andpolypropylene. The duration from the hernia repair to the identification of erosion varied greatly, and 79% of the erosion occurred within 2years after the hernia repair. Various treatment methods were reported, including endoscopic mesh retrieval (15.7%), laparoscopic mesh removal (11.8%), surgical mesh removal (19.6%); however, distal esophageal resection and gastric resection were reported in 19.6% and 5.9%, respectively. Some patients had to receive tube feeding. The true incidence of mesh erosion after hiatal hernia repair may be higher than previously reported, and the erosion is more prone to occur after recurrent hiatal hernia repair. Mesh erosion can result in severe morbidity and sometimes require complex organ resection. Different kinds and shapes of prosthetic meshes can cause erosion; therefore, mesh should be used very selectively for hiatal hernia repair. The patient should be informed about the mesh placement and the possible mesh-related complications.

HIPEC in treatment of gastric cancer with high risk of carcinomatosis: Russians Regional Centre experience.

e15501 Background: Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is a treatment method in patients with gastric cancer having a high risk of development of peritoneal carcinomatosis which can improve treatment results. Methods: HIPEC in a "prophylactic" setting in gastric patients having a high risk of peritoneal carcinomatosis development has been applied in our centre since 2015. This method was used in cases of diffuse type poor-differentiated tumor histology , massive tumor invasion of the stomach serosa and relatively young age of the patient. A “closed” HIPEC technique, with 3 inflow and 3 outflow catheters, RAND HT performer and 7 liters of saline solution with 200 mg cisplatinum was performed. Up to this moment we have treated 8 patients with gastric surgery added by HIPEC. There were 4 men and 4 women. Median age was 48 years. In 2 cases distal subtotal gastric resection was performed, in other 6 cases - total gastrectomy with a D2 lymph nodes dissection. In 2 cases was also performed an edge resection of the pancreas. 2 procedures were performed in cases with ovarian metastases and local diaphragm canceromatosis, with complete cytoreduction. Median surgery time was 4 hours. Results: There was no mortality in early postoperative period, with 25% morbidity. In one case a severe postoperative pancreonecrosis occured which required several re-operations. In one case there has been an acute renal failure, after 3 dialyse sessions the renal function was recovered. Median post-operative hospital stay was 20 days. Two patients are alive without progression on 14 and 23 months respectively. One patient developed a local anastomotic recurrence, no other progression was found, and anastomosis extirpation was performed. Patients having ovarian metastases and local canceromatosis progressed in 6 months, in other cases progression was found in 6 to 12 months. Conclusions: The use of HIPEC doesn't result in elevation of complications or mortality rate. It shows a trend to improve the results of treatment gastric cancer. In cases of already existing canceromatosis the effectiveness of HIPEC is doubtful.

Features of Histological Forms of Tumor Growth in Patients Who Underwent Combined Surgery for Stomach Cancer

The morphological type of tumor is a crucial factor in selecting the type and volume of surgery.The objective of the research was to determine the effect of tumor histological type on survival rates in patients with locally advanced stomach cancer after combined surgery.Materials and methods. The study included 990 patients; there were 714 men and 276 women. All patients underwent combined surgery: distal subtotal gastric resection was performed in 222 cases; proximal subtotal gastric resection was used in 129 cases; gastrectomy was applied in 639 cases. Statistical analysis of the obtained data was performed using the SPSS 13.0 software program. The results were considered statistically significant at p&lt;0.05.Results. The study of certain morphological types of tumor depending on the patients’ age and sex, as well as clinical and morphological features revealed a significant predominance of adenocarcinoma (77.1%) over other types and a significantly smaller number of undifferentiated tumors – 20.6%; squamous cell cancer and small-cell cancer constituted 1.3% and 1.0%, respectively. The average life expectancy after surgery was 37.51±2.69 months (p=0.021); in women, it was slightly higher compared to men – 43.75±5.70 months vs. 35.13±3.02 months (p=0.057). The overall 5-year survival rate for all patients was 17.32±1.49%; for men – 16.11±1.72% (p=0.005), for women – 20.46±2.99% (p=0.399); however, these differences were not statistically significant (p=0.087).Conclusions. After surgery, there were no significant differences in the average life expectancy of patients with the same histological forms of gastric adenocarcinoma between men and women (p&gt;0.05), while significant differences were observed between patients (both men and women) with adenocarcinoma and undifferentiated adenogenic stomach cancer (p&lt;0.05).

Ways to solve the issues of surgical treatment of stomach cancer

Surgical method is the only effective method of stomach cancer treatment. On the basis of dividing the stomach into angiological segments, lymphogenic metastasis was studied, classification of gastric cancer and extraligamentous lymph nodes localizations was created. Based on the performed surgeries working classification of extended lymphodissection was suggested. The data on the formation of esophageal-intestinal anastomosis, identification of the origin of key complications after gastrectomy are given. By introducing single-raw esophago-jejunal anastomosis it was possible to almost completely eliminate complications leading to death which together account for up to 90% of the complications: suture failure, pancreatitis and pancreatic necrosis. The volume of the resected stomach was revised without worsening long-term treatment results. During gastrosplenectomies for ablastic block dissection of lymph nodes the author proposes standard binding of the splenic vessels - proximal to the left gastroepiploic artery arising from the splenic artery. The remaining part of the pancreas after gastrosplenectomy with pancreas resection is proposed to be stitched using atraumatic sutures, which avoids formation of pancreatic fistula. In the clinic we developed esophagogastrosplenectomy from laparoscopic mediastinal access with isoperistaltic right colon graft for esophageal reconstruction with anastomosis located in the neck, antethoracic esophageal reconstruction with graft from the large curvature of the stomach, as well as created original drainages of our own design, which allowed excluding peritonitis without inconsistency of the sutures and abscesses of the abdominal cavity. The author concludes that gastrectomy and subtotal distal gastric resection according to his original methods are an effective tool in the surgical treatment of gastric cancer.

Gastric adenocarcinoma with choriocarcinomatous differentiation in the remnant stomach, 54 years after Billroth II partial gastrectomy

The gastric remnant cancer is defined as a cancer that has developed 5 or more years after distal gastric resection for benign diseases of the stomach. The choriocarcinomatous differentiation of adenocarcinoma in the stomach is a very rare tumor. A 75-year-old woman underwent resection of remnant stomach which she had operated for benign gastric pathology 54 years ago. Pathologic examination of the resection revealed areas of choriocarcinomatous differentiation in addition to classical adenocarcinoma. In the literature on English language, this report presents the first case of adenocarcinoma associated with choriocarcinomatous differentiation in the gastric remnant. The treatment of these patients depends on the clinical setting, and early diagnosis is an important factor for the treatment strategies. Therefore, due to the probability of arising adenocarcinoma in the remnant stomach, the patient should be investigated with endoscopic examination periodically, despite the long postoperative period.
