Laparoscopic Compared with Open D2 Gastrectomy on Perioperative and Long-Term, Stage-Stratified Oncological Outcomes for Gastric Cancer: A Propensity Score-Matched Analysis of the IMIGASTRIC Database.

Simple SummaryGastric resection with D2 lymphadenectomy is considered the gold standard for the treatment of both advanced and early gastric cancer with lymph node metastasis. The performance of D2 lymphadenectomy is technically challenging and represents a key factor in improving patients’ survival. For these reasons, the execution of gastrectomy with D2 lymphadenectomy using the traditional open surgical technique still represents the most widespread approach and, based on current international guidelines, the indication for laparoscopic surgery is limited to early gastric cancer that does not require a D2 lymphadenectomy. The present study aimed to investigate the use of laparoscopic versus open surgical approaches in performing gastrectomy with D2 lymphadenectomy for cancer in terms of intraoperative and postoperative outcomes and long-term survival. The study was conducted using the data collected in the International study group on Minimally Invasive surgery for Gastric Cancer (IMIGASTRIC) international database.Background: The laparoscopic approach in gastric cancer surgery is being increasingly adopted worldwide. However, studies focusing specifically on laparoscopic gastrectomy with D2 lymphadenectomy are still lacking in the literature. This retrospective study aimed to compare the short-term and long-term outcomes of laparoscopic versus open gastrectomy with D2 lymphadenectomy for gastric cancer. Methods: The protocol-based, international IMIGASTRIC (International study group on Minimally Invasive surgery for Gastric Cancer) registry was queried to retrieve data on patients undergoing laparoscopic or open gastrectomy with D2 lymphadenectomy for gastric cancer with curative intent from January 2000 to December 2014. Eleven predefined, demographical, clinical, and pathological variables were used to conduct a 1:1 propensity score matching (PSM) analysis to investigate intraoperative and recovery outcomes, complications, pathological findings, and survival data between the two groups. Predictive factors of long-term survival were also assessed. Results: A total of 3033 patients from 14 participating institutions were selected from the IMIGASTRIC database. After 1:1 PSM, a total of 1248 patients, 624 in the laparoscopic group and 624 in the open group, were matched and included in the final analysis. The total operative time (median 180 versus 240 min, p < 0.0001) and the length of the postoperative hospital stay (median 10 versus 14.8 days, p < 0.0001) were longer in the open group than in the laparoscopic group. The conversion to open rate was 1.9%. The proportion of patients with in-hospital complications was higher in the open group (21.3% versus 15.1%, p = 0.004). The median number of harvested lymph nodes was higher in the laparoscopic approach (median 32 versus 28, p < 0.0001), and the proportion of positive resection margins was higher (p = 0.021) in the open group (5.9%) than in the laparoscopic group (3.2%). There was no significant difference between the groups in five-year overall survival rates (77.4% laparoscopic versus 75.2% open, p = 0.229). Conclusion: The adoption of the laparoscopic approach for gastric resection with D2 lymphadenectomy shortened the length of hospital stay and reduced postoperative complications with respect to the open approach. The five-year overall survival rate after laparoscopy was comparable to that for patients who underwent open D2 resection. The types of surgical approaches are not independent predictive factors for five-year overall survival.

Metachronous carcinoma of the gastric tube following tumour-associated oesophagectomy.

The prognosis of oesophageal carcinoma has improved during the last years. Thereby, the increasing survival has led to increasing occurrence of secondary gastric tube carcinoma (gastric conduit cancer, GTC) following oesophageal tumour resection. A literature review (EMBASE, PubMed), spanning the years 2000 to 2020, identified 342 patients worldwide with a GTC following tumour-related oesophagectomy, of which 306 patients could be included for further analysis. The median age of 306 patients with GTC was 66.4 (39-80) years. 91.2% of patients (n = 279) were male. The median interval between oesophagectomy and GTC was 60.3 (4-236) months. 73.8% of patients (n = 226) were diagnosed as early cancer (EGC, T1) and 26.2% as advanced carcinoma (AGC, > T2; n = 80). Primary oesophagectomy was performed in 97.4% of patients (N = 298) for squamous cell carcinoma. AEG I carcinoma was present in only 5 patients (1.6%). In contrast, 99% (n = 303) of the GTC were found to be adenocarcinomas. One hundred eighty patients (58.8%) could be treated by endoscopic resection (ER). R0 resection was achieved in 82.8% (n = 149). The complication rate was 13.3% (n = 24) and the 30-day mortality 1.1% (n = 2) for ER. Eighty-three patients (27.1%) were treated surgically. These included 13 wedge resections, 25 partial resections and 45 total gastric graft resections with predominantly colon interposition. The R0 rate was 98.8% (n = 82). The postoperative morbidity was 24.1% (n = 20); the 90-day mortality was 6% (n = 5). In 43 patients (14%), palliative chemotherapy or radiotherapy or best supportive care took place. GTC diagnosed early in the EGC stage can be safely managed with ER. In cases of advanced GTC, surgical resection can be a potentially curative approach. Survival times of up to 120months have been described after intervention for GTC.

The Incidence and Risk Factors for Metachronous Gastric Cancer in the Remnant Stomach after Gastric Cancer Surgery.

Background/AimsLess invasive surgical treatment is performed in East Asia to preserve postoperative digestive function and reduce complications such as postgastrectomy syndromes, but there is an issue of metachronous gastric cancer (GC) in the remaining stomach. This study aimed to analyze the incidence of metachronous GC and its risk factors in patients who had undergone partial gastrectomy.MethodsA total of 3,045 GC patients who had undergone curative gastric partial resection at Seoul National University Bundang Hospital were enrolled and analyzed retrospectively for risk factors, including age, sex, smoking, alcohol, Helicobacter pylori status, family history of GC, histological type, and surgical method.ResultsMetachronous GC in the remaining stomach occurred in 35 of the 3,045 patients (1.1%) 23 in the distal gastrectomy group (18 with Billroth-I anastomosis, five with Billroth-II anastomosis), seven in the proximal gastrectomy (PG) group, and five in the pylorus-preserving gastrectomy (PPG) group. Univariate and multivariate Cox regression analyses showed that age ≥60 years (p=0.005) and surgical method used (PG or PPG, p<0.001) were related risk factors for metachronous GC, while male sex and intestinal type histology were potential risk factors.ConclusionsMetachronous GC was shown to be related to older age and the surgical method used (PG or PPG). Regular and careful follow-up with endoscopy should be performed in the case of gastric partial resection, especially in patients with male sex and intestinal type histology as well as those aged ≥60 years undergoing the PG or PPG surgical method.

SURGICAL OUTCOMES IN PATIENTS WITH PROXIMAL GASTRIC CANCER WITHOUT ESOPHAGEAL INVASION

The aim of the study was to improve surgical outcomes in patients with proximal gastric cancer without invading the esophagus.Material and methods. Data regarding lymph node metastasis, short-term postoperative complications/lethality, and long-term outcomes were analyzed in 162 patients with proximal gastric cancer without invasion of the esophagus. All patients underwent gastrosplenectomy with expanded d2 lymph node dissection. The age of the patients ranged from 25 to 91 years, and the median age was 60 years. There were 105 (64.8 %) patients aged over 60 years and 45 (27.8 %) over 70 years.Results. Postoperative complications occurred in 14 patients (8.6 %), 8 of them (4.9 %) died. The 1-, 3- and 5 year survival rates were 85.4 %, 61.8 %, and 38.9 %, respectively.Discussion. In patients with gastric cancer without esophageal invasion, perigastric lymph nodes (№ 3b, 4d) located in segments iv and v are often affected by metastases; therefore, we consider it inexpedient to perform proximal resections in these cases.Conclusion. In patients with proximal gastric cancer without esophageal invasion, it is not advisable to perform proximal subtotal gastric resections due to the high frequency of 3b and 4d lymph node metastases. Postoperative complication and mortality rates were 8.6 % and 4.9 %, respectively in patients who underwent gastrosplenectomy with d2 lymph node dissection.

Simple and Reliable Method for Gastric Subepithelial Tumor Localization Using Endoscopic Tattooing before Totally Laparoscopic Resection.

Background: Totally laparoscopic surgery for early gastric cancer and subepithelial tumors has been popularized worldwide, yet localization of early or small-sized tumors is a persistent challenge due to difficulty being identified with the lack of manual tactile sensation. Thus, accurate localization with tattooing before the surgery would help improve efficiency during surgery. There are multiple methods to localize tumors before laparoscopy, each with varying advantages and disadvantages. The use of endoscopic tattooing with dye has been carried out for several decades due to its safety, lower cost, and convenience. However, there is a lack of studies on endoscopic tattooing before totally laparoscopic resection. Aims: To evaluate the effect of endoscopic tattooing with dye for gastric subepithelial tumors localization before laparoscopic resection and to evaluate the tattooing effect on different locations of tumors in stomach. Method: We retrospectively collected data of patients with gastric subepithelial tumors who underwent endoscopic tattooing before totally laparoscopic resection from 2017 to 2020 in a university affiliated medical center. All patients were analyzed for preoperative characteristics and then categorized into two groups based on tumor locations concerning the difficulty of laparoscopic surgery. The independent t test and Chi-square test were performed to compare perioperative outcome and complications between these two groups. Result: A total of 19 patients were included retrospectively at our center. The individuals were 5 male and 14 female patients with a mean age of 58.2 years old. Most patients had no symptoms, and the tumors were found incidentally in 12 patients (63%). All tumors were identified clearly during laparoscopic resection. The mean tumor size was 2.3 cm. The surgeries took an average of 111 min and a mean of 7 mL blood loss was found. All tumors had negative resection margins with no recurrence during follow-up. Gastrointestinal stromal tumor was the major pathologic diagnosis, found in 12 patients (63%), followed by the leiomyoma in 5 patients (26%). Only three patients had mild adverse effects after surgery and the symptoms were self-limited. Our analysis found no significant difference in preoperative patient characteristics and perioperative outcomes between patients with differing tumor locations. Conclusion: This study is the first and largest report on endoscopic tattooing with dye before laparoscopic resection of gastric subepithelial tumor resection. Our results emphasize that endoscopic tattooing with dye is a safe and reliable method for localizing subepithelial tumors in the stomach prior to totally laparoscopic resection, with no correlation to where the tumor is located.

Minimally Invasive Approach to Gastric GISTs: Analysis of a Multicenter Robotic and Laparoscopic Experience with Literature Review.

Simple SummaryGastrointestinal stromal tumors (GISTs) represent about 1–3% of all gastrointestinal malignancies, of which 50–60% are gastric GISTs (GGs). To the date, surgery represents the best therapeutic option, and the robotic gastric surgery could gain an important role, overcoming many laparoscopic drawbacks. The aim of this study is to evaluate safety and effectiveness of minimally invasive surgery (MIS) for GGs, reporting 10-year experience of three different centers. We included a population of 81 patients who underwent MIS approaches (36 laparoscopy vs. 45 robotic surgery). Seventy-two (72) patients were enrolled in a follow-up program to evaluate the long-term oncological outcomes. Furthermore, we discussed some technical notes and also we analyzed the operative and peri-operative outcomes. In conclusion, our results suggest that the robotic approach might be a suitable treatment, especially for GISTs >5 cm, even located in unfavorable places, despite longer operative time and costs than laparoscopic approach.Background: Gastrointestinal stromal tumors (GISTs) are most frequently located in the stomach. In the setting of a multidisciplinary approach, surgery represents the best therapeutic option, consisting mainly in a wedge gastric resection. (1) Materials and methods: Between January 2010 to September 2020, 105 patients with a primary gastrointestinal stromal tumor (GISTs) located in the stomach, underwent surgery at three surgical units. (2) Results: A multi-institutional analysis of minimally invasive series including 81 cases (36 laparoscopic and 45 robotic) from 3 referral centers was performed. Males were 35 (43.2%), the average age was 66.64 years old. ASA score ≥3 was 6 (13.3%) in the RS and 4 (11.1%) in the LS and the average tumor size was 4.4 cm. Most of the procedures were wedge resections (N = 76; 93.8%) and the main operative time was 151 min in the RS and 97 min in the LS. Conversion was necessary in five cases (6.2%). (3) Conclusions: Minimal invasive approaches for gastric GISTs performed in selected patients and experienced centers are safe. A robotic approach represents a useful option, especially for GISTs that are more than 5 cm, even located in unfavorable places.

Gastric mucormycosis in an immunocompetent patient with fatal outcome

Mucormycosis is being reported as a serious fungal infection with grave outcomes among patients recovering from corona virus disease 2019 (COVID-19). This condition is a new challenge for the physicians in this pandemic situation. Mucormycosis predominantly occurs among patients with immunosuppression but immunocompetent patients are not immune. Here, we report a case of gastric mucormycosis occurring in an immunocompetent patient during the pre-COVID era. Patient presented with fever and upper gastro-intestinal bleeding. Diagnostic work-up confirmed gastric mucormycosis. His response to medical management was unsatisfactory and he died while awaiting a gastric resection.&#x0D; BIRDEM Med J 2021; 11(3): 223-226

Does epidural analgesia modify the risk of complications after gastrectomy?

Introduction. The surgical treatment of Gastric Cancer is associated with overall complication rates as high as 50%. The intent of this study was to assess the impact of epidural analgesia (EA) on postoperative complication rates among patients undergoing gastric resections. Materials and methods. Of the 617 gastric cancer patients who between 2002 and 2010 had undergone stomach resection, 246 (39.8%) were administered EA. Groups with and without EA were compared. Results. The general rate of complications was lower in the EA group in the univariable analysis – 38.5% vs. 54.2% (odds ratio [OR]: 0.47, 95% confidence interval [CI]: 0.34–0.66, p &lt; 0.001), intra-abdominal abscess (OR 0,28, 95% CI: 0.14–0.59, p = 0.001), pneumonia (OR 0,39, 95% CI: 0.24–0.63, p &lt; 0.001), temperature &gt; 38°C (OR 0.53, 95% CI: 0.37–0.74, p &lt; 0.001) and re-operation (OR 0.53, 95% CI: 0.28–1.00, p = 0.049). These relationships were confirmed in a multivariable analysis for the general number of complications (OR 0.53, 95% CI: 0.37–0.75, p &lt; 0.001), intra-abdominal abscess (OR 0.36, 95% CI: 0.16–0.77, p = 0.009), temperature &gt; 38°C (OR 0.56, 95% CI: 0.39–0.82, p = 0.009), pneumonia (OR 0.42, 95% CI: 0.25–0.71, p = 0.001). Conclusions. Our findings indicate that postoperative treatment with EA for patients undergoing stomach resection is safe and contributes to a reduction in the number of postoperative complications.

Role of Helicobacter pylori in the triggering and evolution of hemorrhagic gastro-duodenal lesions.

The majority of studies concerning Helicobacter pylori (H. pylori) are oriented towards the implication of infection with H. pylori in processes that end in the formation of neoplasia, without assessing the impact of the bacterium in triggering acute gastroduodenal hemorrhagic episodes. The present study includes 166 patients with upper digestive hemorrhage, admitted to the ATI Clinic, the Gastroenterology Clinic or to the Surgery II Clinic of the County Emergency Clinical Hospital in Craiova, Romania between 2017 and 2019. All patients were monitored for evolution and received treatment according to current guidelines, and hemorrhagic lesions were biopsied. In the study group, 56.8% of the patients with upper gastrointestinal bleeding (UGIB) were positive for H. pylori and 43.2% were negative. In patients less than 50 years of age, non-steroidal anti-inflammatory drug (NSAID) use and H. pylori infection had a cumulative effect in causing bleeding lesions, but in patients older than 50 years of age, the use of NSAIDs was replaced by therapies with oral antiplatelet or anticoagulant agents. The need for hemostasis surgery was more common in patients who exhibited H. pylori-positive UGIB compared to H. pylori-negative (16 vs. 9.7%). In patients with H. pylori-positive hemorrhagic lesions, gastric resection was frequently required to obtain hemostasis. Persistence of H. pylori infection in patients with a history of gastric resection (4.1%) still predisposes to a hemorrhagic or neoplastic complication.

TUMOR DO ESTROMA GASTROINTESTINAL (GIST) GIGANTE ASSINTOMÁTICO: REVISÃO DE TEMA A PROPÓSITO DE UM CASO CLÍNICO

GISTs are rare mesenchymal tumors, which may present as millimetric lesions or bulky masses. They are usually clinically silent until they reach a significant size, so their finding is often incidental. We report the case of a 92 – year – old female patient admitted to the Emergency Department due to clinical symptoms of right hypochondrium (RH) pain, nausea and vomiting, developing within a few hours. Clinical examination revealed tenderness in the RH and a palpable painless mass in the epigastric/left upper quadrants, of 10 x 10 cm. Blood tests and ultrasonography confirmed the diagnostic hypothesis of choledocholithiasis and also revealed a solid, heterogeneous mass of 14 x 8 x 9 cm, with cystic areas and cleavage planes. Endoscopic retrograde cholangiopancreatography (ERCP) was performed with endoscopic sphincterotomy (EST) and removal of calculi with no complications. The patient had open surgery so as to approach the gallblader and the mass at the same surgical time. Gastric wedge resection and cholecystectomy were performed. The histological and immunohistochemical analysis of the lesion showed a high-risk GIST. Due to the advanced age of the patient and the existing co-morbidities, it was decided not to perform adjuvant therapy with imatinib, as usually indicated. Review of literature show that giant GISTs of the stomach are rare and usually symptomatic. Complete surgical resection is the standard treatment in locally resectable GISTs, with adjuvant therapy being indicated for high-risk tumors.

Risk factors and risk model of lymph node metastasis in early gastric cancer

To investigate the risk factors of lymph node metastasis in early gastric cancer (EGC) and to develop a risk model for the presence of lymph node metastasis. A total of 172 EGC patients, with a median age of 62(52, 68) years, who underwent gastric cancer resection in the First Affiliated Hospital of Nanjing Medical University from January 2017 to June 2019 were selected. Clinical data of the patients were collected through the case system. Logistic regression analysis was used to determine the variables significantly related to lymph node metastasis. ROC curve and calibration curve were used to evaluate the risk model. The results showed that the lymph node metastasis rate of 172 EGC patients was 19.19% (33/172). Tumor size, depth of invasion, degree of differentiation and vascular tumor thrombus were associated with lymph node metastasis (P<0.05), but age ≥ 60 years (OR=5.556, 95%CI: 1.757-17.569, P=0.004), invasion depth (OR=4.218,95%CI:1.418-12.548, P=0.010) and vascular cancer embolus (OR=13.878,95%CI:4.081-47.196,P<0.001) were independent risk factors for lymph node metastasis of EGC. The consistency index of the risk model based on the above risk factors was 0.8835 (95%CI: 0.818 8-0.948 2). The calibration curve shows that the risk assessment model is in good agreement with the actual results, indicating that the model has high accuracy and discrimination.The most common site of metastasis was group 3, followed by group 4. Therefore, patients over 60 years old with submucosal invasion and vascular tumor thrombus may have a higher risk of lymph node metastasis.

Mucormycosis-induced upper gastrointestinal ulcer perforation in immunocompetent patients: a report of two cases

BackgroundGastrointestinal mucormycosis (GIM) is a rare, opportunistic fungal infection with poor prognosis. Clinically, it is difficult to diagnose GIM owing to its nonspecific clinical symptoms and poor suspicion. The estimated incidence of GIM is inaccurate, and most cases are diagnosed accidentally during surgery or upon postmortem examination. GIM usually occurs in patients with immune deficiencies or diabetes. Here, we report two cases of immunocompetent young patients with GIM who had good prognosis after treatment. Compared to other case reports on GIM, our cases had unusual infection sites and no obvious predisposing factors, which make it important to highlight these cases.Case presentationThe first case was that of a 16-year-old immunocompetent boy who was admitted with gastrointestinal bleeding and perforation due to a gastric ulcer. Strategies used to arrest bleeding during emergency gastroscopy were unsuccessful. An adhesive mass was then discovered through laparoscopy. The patient underwent type II gastric resection. Pathological examination of the mass revealed bacterial infection and GIM. The second case was of a 33-year-old immunocompetent woman with a recent history of a lower leg sprain. The patient subsequently became critically ill and required ventilatory support. After hemodynamic stabilization and extubation, she presented with hematemesis due to exfoliation and necrosis of the stomach wall. The patient underwent total gastrectomy plus jejunostomy. The pathology results revealed severe bacterial infection and fungal infection that was confirmed as GIM. The patient fully recovered after receiving anti-infective and antifungal treatments.ConclusionsNeither patient was immunosuppressed, and both patients presented with gastrointestinal bleeding. GIM was confirmed via pathological examination. GIM is not limited to immunocompromised patients, and its diagnosis mainly relies on pathological examination. Early diagnosis, timely surgical treatment, and early administration of systemic drug treatment are fundamental to improving its prognosis.

Active smokers show ameliorated delayed gastric emptying after pancreatoduodenectomy

BackgroundDelayed gastric emptying (DGE) is the most common complication following pancreatoduodenectomy (PD). The data about active smoking in relation to gastric motility have been inconsistent and specifically the effect of smoking on gastric emptying after PD has not yet been investigated in detail.Methods295 patients at our department underwent PD between January 2009 and December 2019. Patients were analyzed in relation to demographic factors, diagnosis, pre-existing conditions, intraoperative characteristics, hospital stay, mortality and postoperative complications with special emphasis on DGE. All complications were classified according to the definitions of the International Study Group on Pancreatic Surgery.Results274 patients were included in the study and analyzed regarding their smoking habits (non or former smokers, n = 88, 32.1% vs. active smokers, n = 186, 68.6%). Excluded were patients for whom no information about their smoking habits was available (n = 3), patients who had had gastric resection before (n = 4) and patients with prolonged postoperative resumption to normal diet independently from DGE (long-term ventilation > 7 days, fasting due to pancreatic fistula) (n = 14). Smokers were younger than non-smokers (61 vs. 69 years, p ≤ 0.001) and mainly male (73% male vs. 27% female). Smoking patients showed significantly more pre-existing pulmonary conditions (19% vs. 8%, p = 0.002) and alcohol abuse (48% vs. 23%, p ≤ 0.001). We observe more blood loss in smokers (800 [500–1237.5] vs. 600 [400–1000], p = 0.039), however administration of erythrocyte concentrates did not differ between both groups (0 [0–2] vs. 0 [0–2], p = 0.501). 58 out of 88 smokers (66%) and 147 out of 186 of non-smokers (79%) showed malign tumors (p = 0.019). 35 out of 88 active smokers (40%) and 98 out of 188 non- or former smokers (53%) developed DGE after surgery (p = 0.046) and smokers tolerated solid food intake more quickly than non-smokers (postoperative day (POD7 vs. POD10, p = 0.004). Active smokers were less at risk to develop DGE (p = 0.051) whereas patients with pulmonary preexisting conditions were at higher risk for developing DGE (p = 0.011).ConclusionsOur data show that DGE occurs less common in active smokers and they tolerate solid food intake more quickly than non-smokers. Further observation studies and randomized, controlled multicentre studies without the deleterious effect of smoking, for instance by administration of a nicotine patch, are needed to examine if this effect is due to nicotine administration.

East meets West: the initial results of laparoscopic gastric cancer resections with Eastern principles in a single Western centre - a propensity score-matched study.

We compared the initial experience of totally laparoscopic gastric cancer surgery with Eastern principles with the results of propensity score-matched counterparts operated with open surgery. From 1163 patients stored in our database, 62 PSM patients were selected for this study. The quality control was assured with video documentation and standardisation of the procedures. According to the distribution of age, comorbidities, and general health, patients in the LG and OG were well-balanced. Most of the patients in both groups had advanced gastric cancer (69.3%). In the OG, 67.8% of patients received a total gastrectomy, as well as 54.8% of patients in the LG. There was no significant difference in the postoperative mortality between groups. The recovery of bowel function was significantly faster, and postoperative pain was significantly decreased in the LG. Compared to the OG, the inflammatory response was significantly smaller in the LG. There was no significant difference in the overall survival between LG and OG patients. We have shown that laparoscopic gastrectomy with Eastern principles can be safely introduced in a high-volume Western centre with sufficient laparoscopic training. We have also shown that laparoscopy offers a significant faster bowel function recovery, less postoperative pain, and a smaller inflammatory response.

Analysis of Prognostic Factors Affecting Short-term and Long-term Outcomes of Gastric Cancer Resection.

The aim of this study was the analysis of the influence of prognostic factors on short- and long-term outcomes of gastric cancer resection. A database of 709 patients who had gastric cancer resection between 2007 and 2015 was compiled. Total gastrectomy (TG) and subtotal proximal gastrectomy (SPG) significantly increased the risk of overall complications (p=0.0015 and 0.0173, respectively) and surgical complications (p=0.0141 and 0.0035, respectively). Moreover the resection of an additional organ was an independent prognostic factor of overall complications (p<0.0001), systemic complications (p=0.0503), surgical complications (p<0.0001) and relaparotomy (p=0.0259). T stage (p<0.0001), N stage (p<0.0001), M stage (p<0.0001) and radical resection (p<0.0001) significantly affected 5-year survival rates. Early diagnosis and radical resection was crucial in 5-year survival rates. However, the type of gastrectomy and the resection of an additional organ were the most important factors in short-term outcomes of treatment for such patients.

High-Grade Primary Gastric Lymphoma: A Retrospective Review of Clinicopathologic Features and Prognostic Factor Analysis in 214 Patients with High-Grade Gastric Lymphoma.

Stomach is the most common site of primary extranodal lymphoma. In addition to the ‘classical' indolent marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT)-type, aggressive histologies are also encountered in the stomach, the majority being classified as diffuse large B-cell lymphoma (DLBCL). We reviewed all patients treated at four institutes between 1990 and 2004 for a NHL exhibiting primary gastric involvement with high-grade pathologies to analyze clinicopathologic features and clinical prognostic factors. A survey of 444 gastric lymphoma including MALT-lymphoma who had been diagnosed identified 260 patients with high-grade gastric lymphoma. Among these 260 cases, 214 high-grade gastric lymphoma patients who had been treated and evaluated were included in this analysis. T-cell lymphomas and mantle cell lymphomas were included in this analysis to reflect poor outcomes of these subtypes. The median age of the 119 male and 95 female patients was 55 years (range 21–81 years), many of the patients (63%) had a good performance status (0 or 1). The most of the patients (87%) had DLBCLs. Other pathologic subtypes were as follows: mantle cell lymphoma in 7 patients, Burkitt lymphoma in 5 patients, other high-grade B-cell lymphoma in 2 patients, and T-cell lymphoma in 14 patients (6.5%). Among these 187 DLBCL patients, 22 patients (10%) included low-grade component. Manay of the patients (63%) showed localized stage I or II diseases according to the Mushoff staging system. According to the International Prognostic Index (IPI), 66% of the patients showed low or low-intermediated risk, 34% showed high or high-intermediated risk. All the patients treated with surgery and/or combination chemotherapy with or without radiotherapy. The main chemotherapy was CHOP or CHOP-like regimens. Actually, through this analysis, we observed the change of treatment trend. Since 2000, gastric resections were performed in only 13 patients, who had been complicated with bleeding or perforation. The overall response rate to treatment was 82% (Complete Response (CR); 69%, Partial Response (PR); 13%). The median Progression-Free Survival (PFS) was 54 months (95% C.I.; 7–102). The median Overall Survival (OS) was 90 months (95% C.I.; 46–135). The prognostic factor analysis showed IPI had independent prognostic significance for OS by Cox-regression test (p = 0.000). We also identified the presence of ascites as independent prognostic factor, as well as IPI (p = 0.038). According to the subgroup analysis, M1 node (by AJCC staging system) positivity on pre-treatment CT-scanning was associated with poor clinical outcome (p = 0.0000 by log-rank test) for localized stage I or II patients. In conclusion, our cohort of patients represents one of the most important series that show the clinicopathologic feature, treatment outcome, and prognostic factors of high-grade primary gastric lymphoma.

Incisional hernia after minimally invasive gastrectomy in gastric cancer patients.

PurposeAlthough there are several studies on the incidence and risk factors for incisional hernia (IH) after open surgery, data about IH after minimally invasive surgery (MIS) for gastric cancer is rare. This study aimed to identify the incidence and risk factors for IH after MIS in gastric cancer patients.MethodsWe analyzed the clinicopathologic data of patients who had laparoscopic or robotic gastric cancer surgeries between January 2006 and July 2019 at National Cancer Center, South Korea. Risk factors for development of IH were investigated with univariate and multivariate analyses.ResultsA total of 2,769 patients underwent laparoscopic-assisted or robot-assisted gastrectomy with extracorporeal gastric resection and reconstruction, while 1,469 underwent totally laparoscopic or totally robotic gastrectomy (TLRG) with intracorporeal gastric resection and reconstruction. IH repair was performed in 23 patients (0.5%) after gastric cancer surgery. In the multivariate analysis, female sex (odds ratio [OR], 5.23; 95% confidence interval [CI], 2.03–13.43; p = 0.001), high body mass index (BMI) of ≥25 kg/m2 (OR, 4.23; 95% CI, 1.73–10.35; p = 0.002), larger tumor size (OR, 21.67; 95% CI, 5.37–87.34; p < 0.001), and intracorporeal procedure (OR, 5.63; 95% CI, 2.15–14.61; p < 0.001) were independent significant risk factors for IH.ConclusionIH after MIS for gastric cancer is not common. Female sex, high BMI, large tumor size, and intracorporeal procedure were significant risk factors for it in this study. Therefore, in patients with risk factors, surgeons should cautiously close the abdominal wall access wound after MIS for gastric cancer, to prevent IH.

Evaluation of oesophageal and gastric resection outcomes in a small-volume unit

IntroductionOesophagogastric resections continue to be a major surgical challenge with high morbidity, this has led to a worldwide trend for centralisation of these complex surgeries. However, there is no clear agreement on what constitutes a high-volume centre, leading to worldwide disparity. We evaluate our experience of oesophagogastric resection in a small volume unit to seek other factors that influence patient outcome. MethodsWe analysed 173 consecutive oesophagogastric resection from 2010 to 2020. The primary outcome was 30-day mortality and secondary outcome included peri-operative morbidity, length of stay, lymph node harvest, R0 resection. Collected continuous data were compared using the Mann-Whitney test and categorical data using the chi-squared test and expressed as p value. ResultsOf the 173 patients, 94 (54%) underwent hybrid minimal invasive esophagectomy (HIMO) and 79 (46%) underwent gastrectomy. 135 (78%) patients received Neoadjuvant therapy. The site of tumour was GOJ in 29%, distal stomach in 26% and distal oesophagus in 20%. Perioperative morbidity was observed in 18 (19%) after esophagectomy and 9 (11.4%) after gastrectomy. The median lymph node harvest was 18 (range 5–42) and 168 patients (97%) had longitudinal R0 resection. The most common complication was neurological seen in 3.6% followed by pulmonary complication and anastomotic leak seen in 5 patients (3%) each. The median in hospital stay was 6 days and the 30 day mortality was 2.9% with one year survival of 87%. ConclusionSmall volume centres can produce comparable results. The outcomes depend on multifold parameters which include surgeon's experience in the field, ability to adhere to protocols and procedures and strong interpersonal relationship with individual patients.

Immediate and long-term results of proximal gastric resection depending on the methods of the digestive tract continuity restoring

Proximal gastric resection (PGR) is still one of the most difficult and dangerous surgical interventions, and it is the only method of curative treatment of diseases of the cardiac part of the stomach in many cases. 5 types of gastrointestinal reconstruction are mainly performed after PRG: submerged rectal esophagogastroanastomosis, antireflux interposition of the jejunal segment, interposition of the jejunal segment of the jejunal pocket, interposition of the jejunal segment as a double tract and reconstruction with the formation of a gastric tube. Modern literature includes many works devoted to the development of methods of physiological reconstruction after subtotal and total removal of the stomach; however, none of the existing methods is recognized as optimal. Among the main indicators characterizing the effectiveness of PGR are the frequency and severity of the development of a large group of functional disorders, characterized as «diseases of the operated stomach», or «post-gastro-resection disorders», which significantly worsen the quality of life (QOL) and reduce the working capacity, which causes disability of the operated patients Assessment of QoL after surgery for diseases of the cardiac stomach is a fundamentally important component of monitoring the effectiveness of treatment and, therefore, allows one to determine the indications for certain types of interventions. The available world scientific literature does not provide convincing data on the assessment of QOL in patients after proximal resection for cardiac part of the stomach diseases, since there are no clear criteria for its assessment depending on the chosen methods and methods of reconstruction of gastrointestinal tract (GIT). In this regard, there is a need for further study of proximal resection with reconstruction of the gastrointestinal tract in surgical diseases of the cardiac part of the stomach on the basis of analysis of immediate and long-term results, as well as the quality of life of patients who underwent these surgical interventions.
