Glomus Tumor of the Stomach: A Systematic Review and Illustrative Case Report.

INTRODUCTION: Glomus tumor (GT) is a rare mesenchymal neoplasm that can be found anywhere throughout the body, including the stomach. Our goal was to present a case and a systematic review of the literature, reporting clinical, radiological, surgical, and pathological features of the disease. METHODS: We reviewed Pubmed and SCOPUS for all case reports and case series published after 2000. Papers written in languages different from English and letters to the editor were excluded. Screening and data extraction were performed following the PRISMA guidelines. RESULTS: A total of 89 studies were included in the systematic review, consisting of 187 cases of gastric glomus tumor. Mean age was 52 (18-90); most patients were female (61%). The most common clinical presentation was epigastric pain (33.9% of cases). The gastric antrum was the most frequently involved site (75.3%). Mean tumor size was 2.82 cm (0.8-17). Preoperative diagnosis was achieved in 22 cases, mostly by endoscopic ultrasound (EUS)-guided biopsy. Wedge resection was performed in 62% of treated patients. Smooth muscle actin was expressed in all cases with available immunohistochemistry. Malignant GT was reported in 11 cases. DISCUSSION: Epigastric pain and bleeding were the most common symptoms at presentation in patients with diagnosis of glomus tumor. EUS-guided fine needle aspiration can be useful for preoperative diagnosis. Endoscopic elastosonography is a promising tool for the differential diagnosis of gastric submucosal lesions, including glomus tumors. The treatment of choice is wedge resection with adequate free margins. A laparoscopic approach is warranted when technically feasible. Since malignant gastric GTs have been described, long-term follow-up is suggested after surgical excision.

Total pancreatectomy as alternative to pancreatico-jejunal anastomosis in patients with high fistula risk score: the choice of the fearful or of the wise?

PURPOSE: Patients with fistula risk score (FRS) ≥7 are at the highest risk of developing clinically relevant post-operative pancreatic fistula (CR-POPF). There is no agreement on the management of this subpopulation. The primary outcome of the study was the definition of the role of intraoperative completion pancreatectomy (ICP) in patients at high risk for CR-POPF, as an alternative to high-risk pancreaticoduodenectomy (PD). METHODS: This is an observational study set in a single tertiary referral center. Patients scheduled for PD in our center between 2010 and 2019 with FRS ≥7 were included in the study. Data were prospectively collected. RESULTS: A total of 738 patients were scheduled for between 2010 and 2019, and 62 had FRS ≥7. Thirty-five patients were managed with PD and pancreatico-jejunal anastomosis (group A), and 27 with ICP (group B). Overall complication rate was significantly higher in group A than group B (95 versus 59%; p=0.005) and there was a not significantly higher rate of major complications (Clavien-Dindo ≥3) (43 versus 26%; p=0.192). In group A, 49% of patients had a CR-POPF. Median post-operative length of stay was 15 days in group A and 12 in group B (p=0.043). Readmission was observed only in group A (26%). In multivariate analysis, PD was an independent predictive factor of major post-operative morbidity (RR 9.27; CI 1.74-49.31). No patients in either group suffered major adverse events related to endocrine and exocrine insufficiency. CONCLUSION: In high-FRS patients, ICP has good short-term outcomes relative to PD without major long-term events related to endocrine and exocrine insufficiency. ICP could be considered as a feasible alternative in selected cases.

Facing adenocarcinoma of distal esophagus and esophagogastric junction: a CROSS versus FLOT propensity score-matched analysis of oncological outcomes in a high-volume institution.

Multimodality treatments are the gold standard for advanced resectable gastroesophageal cancer. Neoadjuvant CROSS and perioperative FLOT regimens are adopted for distal esophageal and esophagogastric junction adenocarcinoma (DE/EGJ AC). At present, none of the approaches is clearly superior in the context of a curative-intent multimodal treatment. We analyzed consecutive patients treated with CROSS or FLOT and surgery for DE/EGJ AC between August 2017 and October 2021. Propensity score matching was performed to balance baseline characteristics of patients. The primary endpoint was disease-free survival. Secondary endpoints included overall survival, 90-day morbidity/mortality rates, pathological complete response, margin-negative resection, and pattern of recurrence. Of the 111 patients included, 84 were correctly matched after PSM, 42 in each group. The 2-year DFS rate was 54.2% versus 64.1% in the CROSS and FLOT group, respectively (p = 0.182). Patients in the CROSS group showed a lower number of harvested LN when compared to the FLOT group (29.5 versus 39.0 respectively, p = 0.005). A higher rate of distal nodal recurrence was found in the CROSS group (23.8% versus 4.8%, p = 0.026). Although not significant, the CROSS group showed a trend toward higher rate of isolated distant recurrence (33.3% versus 21.4% respectively, p = 0.328), together with a higher rate of early recurrence (23.8% versus 9.5% respectively, p = 0.062). FLOT and CROSS regimens for DE/EGJ AC offer similar DFS and OS, together with comparable morbidity/mortality rates. CROSS regimen was associated with a higher distant nodal recurrence rate. Results of ongoing randomized clinical trials are awaited.

Indocyanine-green fluorescence guided anatomical segmentectomy for HCC with portal thrombosis: the counter-fluorescence technique.

A surgical technique to intra-operatively define segmental boundaries by US-guided bimanual liver compression has been described by the authors, but this procedure is contraindicated in case of portal tumor thrombus. A technique to overcome this limitation is described. A patient with a single hepatocarcinoma nodule and segment 8 (S8) portal branch thrombosis was submitted to the procedure. Anatomical demarcation of S8 was achieved by hilar clamping of the common hepatic artery, intravenous injection of indocyanine green (ICG), and fluorescence imaging analyses of the liver. The procedure was feasible and the demarcation of S8 was visible within 2 min from the iv injection of ICG in a counterstaining fashion. Then S8 segmentectomy was safely carried out. This novel approach seems feasible, providing a reliably anatomical and conservative removal of HCC with portal branch tumor thrombus.

Anastomotic Leakage in Rectal Surgery: Role of the Ghost Ileostomy.

BACKGROUND/AIM: A protective ileostomy performed during anterior resection in rectal surgery is considered a good practice to prevent anastomotic leakage. A derivative ostomy seems to be able to minimize the clinical consequences of an anastomotic leakage, but not to prevent it. The present study examined the role of the ghost ileostomy in anastomotic leakage following rectal surgery. PATIENTS AND METHODS: This study included 82 patients that had undergone anterior rectal resection. A total of 32 patients underwent ghost ileostomy (GH) and 50 patients underwent ileostomy (IL). RESULTS: The incidence of anastomotic leakage was equal to 7.32%, occurring in 3 patients of the IL group (6%) and in 3 patients of the GH group (9.38%), in which the ghost was converted into derivative ileostomy. Therefore, 47 patients with IL (94%) underwent useless ileostomy implementation, and 29 patients (90.62%) with GH avoided ileostomy. CONCLUSION: In this study no increase in morbidity and mortality rate was observed. Therefore, ghost ileostomy proved to be as safe as ileostomy in terms of outcome, morbidity and mortality.
