[Somatostatin-analogue treatment of severe esophagitis after gastrectomy]

This article presents a case of successful treatment of severe erosive esophagitis, which developed after total gastrectomy. The patient suffered from a poorly differentiated, diffuse gastric carcinoma with subtotal gastric outlet obstruction, accompanied by Helicobacter pylori-associated type b gastritis. A few weeks after Helicobacter eradication followed by successful surgery, swallowing of nutrition became impossible due to severe erosive esophagitis. Histologically there was no evidence of tumor infiltration in this organ. After numerous unsuccessful attempts using established conventional pharmacotherapy options, the problem could be solved by daily subcutaneous somatostatin-analogue (octreotide) injections. The patient started to eat again, and endoscopically/histologically the severe inflammation significantly improved. Attempts to reduce the daily injections, undertaken by the patient, resulted in relapses within a few days. Octreotide was well tolerated by the patient.

Comparison of efficacy of pharmacological therapies for gastric endoscopic submucosal dissection-induced ulcers: a systematic review and network meta-analysis

Objectives: This study aimed to compare the efficacy of various anti-ulcer medications in preventing delayed bleeding and promoting ulcer healing after ESD.Methods: Asystematic search was conducted for articles up to August2019. The treatments of iatrogenic ulcer were analyzed by Bayesian network meta-analysis.Results: The analysis included 28 studies. Six treatments were compared. For the prevention of delayed bleeding, potassium-competitive acid blocker (P-CAB) alone was superior to proton-pump inhibitor (PPI) alone [RR = 1.02, 95%CI (1.00, 1.05)]. Treatments based on P-CAB tended to be better than the non-P-CAB groups [RR = 1.05, 95%CI (1.03, 1.07)]. Concerning the ulcer healing rate at 4 weeks, the combined treatment of PPI and mucoprotective agent (MP) was superior to PPI alone [RR = 1.81, 95%CI (1.19, 2.76)] and P-CAB alone [RR = 2.75, 95%CI (1.02, 7.44)]. At 8 weeks, PPI+MP and P-CAB+MP tend to be superior to than the other four groups. The healing effect of MP-based therapies was better than that of non-MP groups at 4 weeks [RR = 1.63, 95%CI (1.32, 2.01)] and 8 weeks [RR = 1.06, 95%CI (1.02, 1.11)].Conclusion: P-CAB may prevent delayed bleeding, but not significantly. MP agents have the potential to heal post-ESD ulcers.

Role of mucoprotective agents in endoscopic submucosal dissection-derived ulcers: A systematic review

BACKGROUND

Currently, it is still unclear whether adding a mucoprotective agent to a proton pump inhibitor (PPI) results in better outcomes compared with using a PPI alone in patients with post-gastric endoscopic submucosal dissection (ESD) ulcers. This study aimed to examine the efficacy of PPI alone versus combination treatment in healing of post-gastric ESD ulcers, as well as on delayed bleeding and amount of blood transfused.

METHODS

A systematic search of MEDLINE, EMBASE, Cochrane, and ISI Web of knowledge databases, up until May 2017, for randomized trials comparing PPI alone versus PPI plus a mucoprotective drug in achieving ulcer healing in patients undergoing gastric ESD was performed. The primary outcome is scarring stage on endoscopic assessment at 4 or 8 weeks after gastric ESD.

RESULTS

From an initial 3071 citations, eight articles (n = 953 lesions from 934 patients) were analyzed. Patients receiving combination treatment achieved a scarring stage significantly more often than those on a PPIs alone at 4 or 8 weeks after ESD, (risk ratio = 1.36, 95% CI; 1.06-1.75). No study reported amount of blood transfused. There were no significant between treatment-group differences in terms of delayed bleeding (risk ratio = 0.58, 95% CI; 0.17-1.99). Neither location of ulcer nor Helicobacter pylori infection was related to ulcer scarring stage.

CONCLUSION

The limited evidences suggested combination treatment may be more effective in accelerating the process of ulcer healing in patients undergoing gastric ESD than the use of PPI alone, but does not appear to alter delayed bleeding risk.

The development of a treatment protocol for patients with chronic radiation-induced rectal bleeding

BACKGROUNDS AND METHODS: This study reviews the clinical features and reports the preliminary results of treatment of 34 consecutive patients with clinically significant bleeding from chronic, radiation-induced proctitis, using a combination of endoscopic YAG Laser and the application of topical formalin dressings to the rectal mucosa.

RESULTS

Bleeding ceased in 25 patients (74%); bleeding continued but occurred only slightly and occasionally in five patients (15%); and three patients required operation to control the bleeding (9%). One patient relapsed after treatment and died while receiving a further transfusion.

CONCLUSIONS

This experience has been used to develop a management protocol for patients with this serious complication.

Review article: functional dyspepsia--should treatment be targeted on disturbed physiology?

In patients who present with chronic unexplained upper abdominal pain or discomfort (functional dyspepsia), therapy should ideally be targeted on correcting the individual's disturbed pathophysiology. Here, putative mechanisms implicated in functional dyspepsia and potential approaches to therapy are critically reviewed in order to determine if targeting treatment is of value. Pharmacological therapies reviewed include those that aim to correct disordered gastric emptying (e.g. cisapride, dopaminergic receptor antagonists, macrolides), reduce visceral hypersensitivity (e.g. somatostatin analogues, cholecystokinin antagonists, opioid agonists, serotonin type 3 receptor antagonists), reduce gastric acid secretion (e.g. H2-blockers, acid pump inhibitors), cure Helicobacter pylori infection, enhance muscosal defence (e.g. sucralfate, bismuth) or modify central nervous system processes. It is concluded that the imperfectly understood pathophysiology of functional dyspepsia contributes to the paucity of established efficacious therapies.
