Delayed gastric emptying after pancreaticoduodenectomy: A study of the national surgical quality improvement program

BackgroundDelayed gastric emptying (DGE) remains common after pancreaticoduodenectomy (PD). Risk factors for DGE have been difficult to identify due to a lack of a standard definition. The purpose of this study was to identify factors associated with DGE using a standard definition across a national cohort of patients.MethodsA retrospective cohort study of patients who underwent PD from 2014 to 2016 within the ACS-NSQIP pancreatectomy-specific module was performed. Multivariable (MV) regression was used to determine perioperative risk factors for DGE.ResultsOf 10,249 patients undergoing PD, 16.6% developed DGE and were older (65.3 vs. 64.3 years), more often male (62.5% vs. 51.9%), overweight/obese (66.7% vs. 61.3%), and American Society of Anesthesiologist (ASA) class 3 (80.0% vs. 76.0%). Rates of pylorus preservation (41.4% vs. 38.7%) were higher, and median operative time (373 vs. 354 min) longer. On MV analysis, age≥65 years [OR 1.26 (95%CI 1.13–1.41)], male sex [OR 1.54 (95%CI 1.38–1.72), body mass index (BMI) > 30 [OR 1.22 (95%CI 1.06–1.40)], ASA class≥3 [OR 1.24 (95%CI 1.08–1.42)], pylorus preservation [OR 1.08 (95%CI 1.02–1.14)], and longer operative time [OR 1.26 (95%CI 1.13–1.40)] remained associated with DGE. Preoperative chemotherapy was associated with decreased risk of DGE [OR 0.77 (95%CI 0.64–0.93)].ConclusionIn this national, multicenter cohort of patients undergoing PD, 16.6% of patients developed DGE based on a standardized definition. Perioperative factors including age, BMI, ASA class, pylorus preservation, and operative time were associated with increased risk of DGE. Further research is warranted to identify opportunities for prevention via preoperative rehabilitation strategies and treatment.     

Esomeprazole vs pantoprazole effects on cyclosporine levels in kidney transplantation: A randomized clinical trial

Renal allograft survival requires multiple immunosuppressive drugs. This strategy may lead to gastric complications that necessitate gastro‐protective medications, notably, proton pump inhibitors (PPI). This study aimed to compare the influence of pantoprazole and esomeprazole on serum cyclosporine trough levels (C₀) in renal transplant recipients (RTR). A prospective, parallel, open‐label trial was conducted on 47 adult RTR receiving cyclosporine doses adjusted to attain trough concentrations of 100 to 150 μg/L, mycophenolate mofetil (MMF) 750 mg q12 hour and prednisolone at 5 mg daily at Nasser Institute, Cairo, Egypt from January to September 2016. Patients were randomized into the esomeprazole group (25) or pantoprazole group (22) receiving the same dose (40 mg once daily). The study outcomes included clinical signs of rejection and renal function decline, assessed by elevations in serum creatinine, caused by cyclosporine level variations in either of the two study groups. Renal function, C₀ and CBC measurements were measured at baseline and monthly for 6 months. The mean C₀ values were higher in the pantoprazole group than in the esomeprazole group in the sixth month only (P = .007). Serum creatinine level was lower in the sixth month than at baseline in the esomeprazole group (P = .004). There were no signs of rejection biochemical or clinical in any of the study groups. In conclusion, PPIs should be used with caution and doses should be titrated to reach the C₀ targets in RTR, which is of more importance in pantoprazole than esomeprazole to avoid C₀ level elevation or decline affecting the allograft function.     

Tumour size is related to the curability of signet ring cell early gastric cancer with endoscopic submucosal dissection: A retrospective single centre study

Background

Endoscopic submucosal dissection is applied in selected cases of signet ring cell early gastric cancer. However, factors related to curability of signet ring cell early gastric cancer with this method have not been fully evaluated. Our aim was to evaluate factors related to incomplete resection in signet ring cell early gastric cancer with endoscopic submucosal dissection.

Methods

A retrospective analysis was performed on a total of 126 consecutive patients with signet ring cell early gastric cancer who had undergone endoscopic submucosal dissection at the Severance Hospital in Korea, between March 2007 and March 2012. The clinical outcomes were reviewed and factors related to incomplete resection were analysed.

Results

Multivariate analysis showed that large tumour size was the only significant factor related to incomplete resection (P = 0.006; hazard ratio, 1.040; 95% confidence interval, 1.101–1.084). In addition, large tumour size was the only significant factor related to endoscopic size underestimation (P < 0.001; hazard ratio, 1.391; 95% confidence interval, 1.221–1.586). The rate of endoscopic size underestimation was significantly higher in tumours with a size ≥20 mm (P < 0.001).

Conclusions

To improve the curability of signet ring cell early gastric cancer with endoscopic submucosal dissection, larger tumours (especially tumour with a size ≥20 mm) should be resected with a larger margin.     

Three-Year Experience of Pouch Dilatation and Slippage Management after Laparoscopic Adjustable Gastric Banding

Purpose

Pouch dilatation and band slippage are the most common long-term complications after laparoscopic adjustable gastric banding (LAGB). The aim of the study is to present our experience of diagnosis and management of these complications.

Materials and Methods

The pars flaccida technique with anterior fixation of the fundus was routinely used. All band adjustments were performed under fluoroscopy. We analyzed the incidence, clinico-radiologic features, management, and revisional surgeries for treatment of these complications. We further presented the outcome of gastric plication techniques as a measure for prevention of these complications.

Results

From March 2009 to March 2012, we performed LAGB on 126 morbidly obese patients. Among them, 14 patients (11.1%) were diagnosed as having these complications. Four patients (3.2%) had concentric pouch dilatations, which were corrected by band adjustment. Ten (7.9%) had eccentric pouch with band slippage. Among the ten patients, there were three cases of posterior slippage, which were corrected by reoperation, and seven cases of eccentric pouch dilatation with anterior slippage. Three were early anterior slippage, which was managed conservatively. Two were acute anterior slippage, one of whom underwent a revision. There were two cases of chronic anterior slippage, one of whom underwent a revision. The 27 patients who underwent gastric plication did not present with eccentric pouch with band slippage during the follow-up period.

Conclusion

The incidence of pouch dilatation with/without band slippage was 11.1%. Management should be individualized according to clinico-radiologic patterns. Gastric plication below the band might prevent these complications.
