AimAs a result of the difficulty in effective prevention of gastroesophageal reflux, no standard reconstruction procedure after proximal gastrectomy (PG) has yet been established. The double‐flap technique (DFT), or Kamikawa procedure, is an antireflux reconstruction procedure in esophagogastrostomy. The efficacy of DFT has recently been reported in several studies. However, these were all single‐center studies with a limited number of cases.MethodsWe conducted a multicenter retrospective study in which patients who underwent DFT, irrespective of disease type and reconstruction approach, at each participating institution between 1996 and 2015 were registered. Primary endpoint was incidence of reflux esophagitis at 1‐year after surgery, and secondary endpoint was incidence of anastomosis‐related complications.ResultsOf 546 patients who were eligible for this study, 464 patients who had endoscopic examination at 1‐year follow up were evaluated for reflux esophagitis. Incidence of reflux esophagitis of all grades was 10.6% and that of grade B or higher was 6.0%. Male gender and anastomosis located in the mediastinum/intra‐thorax were independent risk factors for grade B or higher reflux esophagitis (odds ratio [OR]: 4.21, 95% confidence interval [CI]: 1.44‐10.9, P = 0.0109). Total incidence of anastomosis‐related complications was 7.2%, including leakage in 1.5%, strictures in 5.5% and bleeding in 0.6% of cases. Laparoscopic reconstruction was the only independent risk factor for anastomosis‐related complications (OR: 3.93, 95% CI: 1.93‐7.80, P = 0.0003).ConclusionDouble‐flap technique might be a feasible option after PG for effective prevention of reflux, although anastomotic stricture is a complication that must be well‐prepared for.
It should be noted that the serum CEA level can become elevated in severe stercoral colitis. Marked elevation of the serum CEA level in stercoral colitis may suggest the necessity of surgery in patients with stercoral colitis.
The incidence of small bowel lymphoma (SBL) is increasing worldwide. In contrast to resectable SBL, the treatment of unresectable SBL is still contentious. Here, we report a case of unresectable SBL that was treated by laparoscopic exclusion of the affected intestine before systemic chemotherapy was administered. An 84-year-old man was diagnosed with primary SBL involving extranodal dissemination. The patient received prophylactic surgery, namely exclusion of the affected intestine. This therapy diminishes well-known and life-threatening complications, such as perforation, bleeding, and obstruction, which may still occur after chemotherapy, and it makes the administration of chemotherapy safer. In addition, the surgery provides easy access for direct endoscopic observation and biopsy, which are otherwise difficult to perform. Follow-up after two courses of chemotherapy showed that the patient had achieved complete remission. In conclusion, the procedure described here may be an effective strategy for unresectable SBL.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
