Billroth II procedure for the treatment of spontaneous gastrointestinal perforation in two cats

CASE DESCRIPTION A 9-year-old castrated male domestic shorthair cat (cat 1) and a 10-year-old castrated male Maine Coon cat (cat 2) were presented for recurrent feline lower urinary tract disease after receiving outpatient care from their primary veterinarians. CLINICAL FINDINGS Physical examination findings for both cats were initially within reference limits. After a short period of hospitalization, both cats developed peritoneal effusion; results of cytologic analysis of a sample of the fluid were consistent with septic peritonitis. During exploratory laparotomy, perforation of the pylorus or proximal portion of the duodenum secondary to ulceration was identified. TREATMENT AND OUTCOME Both cats underwent partial duodenectomy, partial gastrectomy (pylorectomy), and gastrojejunostomy (Billroth II procedure). The cats recovered from surgery and returned to a normal quality of life; however, each had mild episodes of anorexia but maintained a stable body weight. Cat 2 required additional surgery for trichobezoar removal 7 weeks later but recovered quickly. At 7 months after trichobezoar removal, cat 2 developed intermittent vomiting, but clinicopathologic, abdominal ultrasonographic, and upper gastrointestinal tract endoscopic findings were within reference limits. At 9 (cat 2) and 13 (cat 1) months after the Billroth II procedure, both cats were reported to be in good general health and without gastrointestinal signs. CLINICAL RELEVANCE In both cats, the Billroth II procedure was technically straightforward and associated with a full recovery and good medium- to long-term quality of life. A Billroth II procedure could be considered for treatment of cats with large mural lesions in the pyloroduodenal region.

Intussusception after reconstruction following gastrectomy for gastric cancer

Background Gastric cancer is the most prevalent tumor in Chinese men, and surgery is currently the most important treatment. Billroth II and Roux-en-Y are the anastomosis methods used for reconstruction after gastrectomy. Jejunal intussusception is a rare complication after gastric surgery. Main Body Intussusception after gastric surgery occurs mostly at the gastrojejunostomy site for Billroth II reconstruction, and the Y-anastomosis site for Roux-en-Y reconstruction. Many studies have reported that postoperative intussusception appears at the anastomosis after bariatric surgery, while a few have reported intussusception at the anastomosis and its distal end after radical gastrectomy. Conclusion A review was carried out to analyze intussusception after radical gastrectomy with roux-en-y anastomosis during the current situation. And the relevant mechanisms, diagnosis, treatment methods, etc. are described, hoping to provide better guidance for clinicians

P-P01 Impact of gastric resection and enteric anastomotic configuration on delayed gastric emptying after pancreaticoduodenectomy: a network meta-analysis

Background Delayed gastric emptying (DGE) is frequent after pancreaticoduodenectomy (PD). Several randomised controlled trials (RCTs) have explored operative strategies to minimise DGE, however, the optimal combination of gastric resection approach, anastomotic route, and configuration, role of Braun enteroenterostomy remains unclear. Methods MEDLINE, Embase, and CENTRAL databases were systematically searched for RCTs comparing gastric resection (Classic Whipple, pylorus-resecting, and pylorus-preserving), anastomotic route (antecolic vs retrocolic) and configuration (Billroth II vs Roux-en-Y), and enteroenterostomy (Braun vs no Braun). A random-effects, Bayesian network meta-analysis with non-informative priors was conducted to determine the optimal combination of approaches to PD for minimising DGE. Results Twenty-four RCTs, including 2526 patients and 14 approaches were included. There was some heterogeneity, although inconsistency was low. The overall incidence of DGE was 25.6% (n = 647). Pylorus-resecting, antecolic, Billroth II with Braun enteroenterostomy was associated with the lowest rates of DGE and ranked the best in 35% of comparisons. Classic Whipple, retrocolic, Billroth II with Braun ranked the worst for DGE in 32% of comparisons. Pairwise meta-analysis of retrocolic vs antecolic route of gastro-jejunostomy found increased risk of DGE with the retrocolic route (OR 2.1, 95% CrI; 0.92 - 4.7). Pairwise meta-analysis of Braun enteroenterostomy found a trend towards lower DGE rates with Braun compared to no Braun (OR 1.9, 95% CrI; 0.92 - 3.9). Having a Braun enteroenterostomy ranked the best in 96% of comparisons. Conclusions Based on existing RCT evidence, a pylorus-resecting, antecolic, Billroth II with Braun enteroenterostomy may be associated with the lowest rates of DGE.

Extramedullary relapse in a patient with multiple myeloma: a rare cause of gastrointestinal perforation and massive bleeding

Multiple myeloma (MM) patients live longer due to more effective treatment, and we now see previously uncommon manifestations of MM, like extramedullary disease. We present a case of a 74-year-old man known with MM that relapsed with extramedullary manifestations at different locations. One of them as a gastric plasmacytoma (GP). He was successfully treated with chemoradiotherapy (Daratumumab, Bortezomib and Dexamethasone), which resulted in clinical response for 8 months, confirmed by biopsy and histopathology. Perforation of the GP occurred, and he underwent partial gastrectomy (Billroth II gastrojejunostomy). The patient’s disease progressed again 5 months after surgery, and he did not want any additional treatment. He accepted palliative care and died 10 months after the operation. A lack of knowledge about the characteristics and treatment of extramedullary MM exists, and prospective studies to investigate incidence, prognosis and treatment for extramedullary MM are needed for improving the poor prognosis of this manifestation.
