Abstract We report a case of necrosis of a reconstructed gastric tube in a 77-year-old male patient who had undergone esophagectomy. At the time of admission, the patient had active gastric ulcers, but these were resolved by treatment with a proton pump inhibitor. Subtotal esophagectomy with gastric tube reconstruction was performed. Visually, the reconstructed gastric tube appeared to be well perfused with blood. Using indocyanine green (ICG) fluorescence imaging the gastroepiploic vessels were well enhanced and no enhancement was visable 3 to 4 cm from the tip of the gastric tube. Four days after esophagectomy, gastric tube necrosis was confirmed, necessitating a second operation. The necrosis of the gastric tube matched the area that had been shown to lack blood perfusion by ICG angiography imaging. It seems that ICG angiography is useful for the evaluation of perfusion in a reconstructed gastric tube.

Introduction. The objective of the study was to evaluate the presence of different rectosigmoid endometriosis (RSE) vascular patterns using intraoperative indocyanine green (ICG) angiography and their correlation with clinicopathological data. Material and Methods. A prospective pilot study on 30 consecutive symptomatic women affected by RSE and scheduled for minimally invasive surgery between May 2018 and January 2019. ICG was used for the intraoperative evaluation of RSE vascularization. Perfusion grade was classified as follows: 0-1 = no or low fluorescence (hypovascular pattern); 2 = regular fluorescence, similar to healthy surrounding rectosigmoid tract (isovascular pattern); and 3-4 = diffuse or abundant fluorescence (hypervascular pattern). Results. Thirty women were intravenously injected with ICG after nodule exposure. No adverse effects related to ICG use were noted. After a 5- to 50-s latency from ICG injection, the real-time direct visualization of RSE perfusion showed diffuse or abundant fluorescence in 12/30 (40%) women, while in the remaining 18/30 (60%), fluorescence was poor or absent. No statistical differences were observed between the 2 groups regarding preoperative, intraoperative, and histological variables analyzed, except for a maximum diameter of bowel lesions and microvessel density (MVD). Hypovascular nodules had a larger maximum diameter (39.5 ± 15.6 mm vs 30.3 ± 11.4 mm, P < .05) and lower MVD (154.6+/43.6 vs 281.1+/−77.4, P < .05) than hypervascular ones. Conclusions. ICG angiography is a feasible and safe technique to intraoperatively assess RSE vascularization. The majority (60%) of endometriotic nodule presented a hypovascular pattern. The hypovascular pattern seems to be associated with a larger nodule size and lower MVD.

Helicobacter pylori infection, use of nonsteroidal anti-inflammatory drugs (NSAIDs) including aspirin, and smoking are the most important causes of peptic ulcer disease. Peptic ulcer disease is characterized by a history of waxing and waning symptoms of localized, dull, aching pain in the upper abdomen. Bleeding is the most common complication; free perforation of the stomach or duodenum into the peritoneal cavity is uncommon but serious. The diagnosis of peptic ulcer disease is made by endoscopy, which offers an opportunity for biopsy of gastric ulcers (which may be malignant) and reveals important prognostic indicators in patients with bleeding ulcers. A single daily dose of a proton pump inhibitor gives quick relief of symptoms and effective healing of peptic ulcers in 4 to 6 weeks. The management of patients with upper gastrointestinal haemorrhage requires a multidisciplinary medical and surgical approach. Early risk stratification based on clinical and endoscopic criteria allows delivery of appropriate care, with endoscopic intervention now widely accepted as the first line of therapy. This should be followed by administration of a high dose of an intravenous proton pump inhibitor to further reduce recurrent bleeding. Treatment of H. pylori is a cure for peptic ulcer disease in most patients. This usually requires at least two antimicrobial agents, with the most popular triple therapy combining a proton pump inhibitor with any two of amoxicillin, metronidazole, and clarithromycin for 7 to 14 days. Eradication of H. pylori infection, avoidance of high-dose NSAIDs or aspirin, and the maintenance use of proton pump inhibitors in high-risk individuals are the best ways to prevent recurrence of ulcer and ulcer complications.

Purpose. To examine the clinical implications of change in choroidal neovascularization (CNV) size on indocyanine green (ICG) angiography in subjects with idiopathic CNV undergoing bevacizumab therapy.Methods. The charts of subjects with an idiopathic CNV treated by a modified PRN regimen with intravitreal bevacizumab over a 12-month period were retrospectively reviewed.Results. There were 34 subjects included in the analysis. Baseline CNV sizes of less than 1.0 mm2on ICG angiography correlated with complete CNV resolution (P=0.0404), fewer injections delivered (P=0.0002), and better Snellen visual acuity (P=0.0098) at 12 months. Subjects that experienced a 33% or more reduction in CNV size on ICG angiography at 2 months had complete CNV resolution (P=0.0047) and fewer injections (P<0.0001) at 12 months compared to subjects that did not experience a 33% or more reduction in CNV size on ICG angiography at 2 months.Conclusions. Smaller baseline CNV size on ICG angiography resulted in better visual acuity and fewer injections at 12 months, and a reduction of 33% or more in CNV size after 2 months may predict a better clinical course in subjects with idiopathic CNV undergoing bevacizumab therapy.

The aim of the present study was to investigate whether CYP2C19 polymorphism status and gastric emptying are related to healing in patients with gastric ulcers. We studied the CYP2C19 status in seven patients with proton pump inhibitor (PPI)-resistant ulcers, 21 with PPI-sensitive ulcers and 46 healthy volunteers using polymerase chain reaction restriction fragment length polymorphism to detect CYP2C19m1 mutation in exon 5 and CYP2C19m2 mutation in exon 4. Gastric emptying was evaluated using the 13C-acetate breath test. The frequency of phenotypes, indicated by genotypes, did not differ significantly between the three patient groups. The peak time of 13C excretion in patients with PPI-resistant ulcers was significantly longer than that of patients with PPI-sensitive ulcers and healthy volunteers. Our results suggest that rate of gastric emptying, but not CYP2C19 polymorphism, is likely to be an important factor in the delayed healing of patients with PPI-resistant gastric ulcer.

One major cause of peptic ulceration is the use of nonsteroidal anti-inflammatory drugs (NSAIDs). The precise mechanisms through which NSAIDs cause peptic ulceration are unknown, but the discovery that they reduce the production of ‘cytoprotective’ prostaglandins led to the hypothesis that coadministration of exogenous prostaglandins heals and prevents NSAID-induced gastroduodenal ulcers and other mucosal lesions. Studies using high doses of misoprostol have shown that it does have a protective effect; however, gastrointestinal intolerance of this prostaglandin E2analogue is common. Early indications that acid suppression was effective in the management of NSAID-related peptic ulcers came from studies showing that gastric ulcers could be healed by omeprazole in patients who continued to take NSAIDs. Other studies suggested that acid suppression reduces the incidence of mucosal lesions but that standard dose ranitidine protects only against duodenal lesions. Subsequent studies reported that higher dose H2receptor antagonist therapy can protect against both gastric and duodenal ulcers during continued NSAID therapy. An ideal therapeutic strategy would heal NSAID-related ulcers and prevent the development of new NSAID-related lesions and complications in patients who are unable to discontinue NSAID therapy. A number of recent studies indicate that effective acid-suppressive treatment with the proton pump inhibitor omeprazole can achieve these aims. Overall, data from recent studies show that acid suppression with the proton pump inhibitor omeprazole at a dose of 20 mg daily is the most effective means of healing NSAID-associated gastroduodenal lesions and that it is the most effective prophylactic therapy. In the long run, the role of omeprazole will have to be evaluated with respect to its cost effectiveness compared with other strategies and with respect to the development of less damaging NSAIDs.
