Randomized trial of two types of gastrojejunostomy after pancreatoduodenectomy and risk of delayed gastric emptying (PAUDA trial).

BACKGROUND: Delayed gastric emptying (DGE) is the most important cause of an extended hospital stay after pancreatoduodenectomy. Reports suggest that a Roux-en-Y gastroenteric anastomosis may have lower incidence of DGE than a Billroth II reconstruction. The primary aim of this RCT was to compare Billroth II (single loop) and Roux-en-Y (double loop) after pancreatoduodenectomy to determine whether Roux-en-Y reconstruction is associated with a lower incidence of DGE. Secondary endpoints were postoperative complications. METHODS: This was a randomized unblinded single-centre trial without masked evaluation of the main outcome. Patients undergoing pancreatoduodenectomy between 2013 and 2015 were randomized to undergo one of two types of gastroenteric anastomosis for reconstruction. RESULTS: A total of 80 patients were randomized, 40 in each group. The incidence of DGE was the same in patients undergoing Billroth II or Roux-en-Y gastroenteric anastomosis (both 18 of 40 patients; P = 1·000). The grade of DGE was also similar in the Billroth II and Roux-en-Y groups (grade A, both 10 of 40; grade B, 5 of 40 versus 6 of 40; grade C, 3 of 40 versus 2 of 40; P = 0·962). The mortality rate was 3 per cent, with no significant difference between the two groups. There were no differences in the overall rate of postoperative morbidity, relaparotomy rate or duration of hospital stay. CONCLUSION: The incidence and severity of DGE does not differ between single- or double-loop gastroenteric anastomosis performed after pancreatoduodenectomy.

Association Between Subtotal Gastrectomy with Billroth II Anastomosis and Coronary Heart Disease.

BACKGROUND: We assessed the risk of coronary heart disease (CHD) after subtotal gastrectomy with Billroth II anastomosis (SGBIIA) for peptic ulcer disease (PUD). METHODS: The Taiwan National Health Insurance Research Database was used, and 6160 patients undergoing SGBIIA for PUD were identified as the surgical cohort. A total of 24,540 patients from the PUD population not undergoing surgery selected by frequency-matching were identified as the non-surgical cohort. All patients were followed until the end of 2011 to measure the incidence of CHD. RESULTS: The cumulative incidence of CHD was lower in patients with SGBIIA than in those without surgery (16.9 vs 22.9 per 1000 person-year, adjusted hazard ratio [aHR] = 0.79, 95% confidence interval [CI] = 0.71-0.88). The risk of CHD, either acute coronary syndrome (ACS) (aHR = 0.83, 95% CI = 0.75-0.91) or other non-ACS CHD (aHR = 0.78, 95% CI = 0.68-0.88), was lower for the SGBIIA cohort than for the non-surgery cohort (aHR = 0.79, 95% CI = 0.71-0.88) after adjusting for age and the comorbidities of hypertension, diabetes mellitus, hyperlipidemia, stroke, congestive heart failure, chronic kidney disease, and chronic obstructive pulmonary disease. CONCLUSIONS: We found SGBIIA is associated with a reduced risk of CHD for PUD patients.

Clinical course of diabetes after gastrectomy according to type of reconstruction in patients with concurrent gastric cancer and type 2 diabetes.

BACKGROUND: This study was conducted to evaluate course of diabetes after gastrectomy according to type of reconstruction performed for gastric cancer in patients with type 2 diabetes. METHODS: In total, 292 patients with concurrent gastric cancer and type 2 diabetes who underwent curative surgery from January 2000 to December 2010 were enrolled in this retrospective study. No surgery-related complications, tumor recurrence, or distant metastasis occurred within 2 years after surgery. The patients' clinical characteristics were compared according to reconstruction type. Their diabetes status was assessed 1, 6, 12, and 24 months postoperatively. RESULTS: Of the 292 patients, 126 underwent distal gastrectomy with Billroth I reconstruction, 103 underwent distal gastrectomy with Billroth II reconstruction, and 63 underwent total gastrectomy with Roux-en-Y reconstruction. The operation type was significantly correlated with the outcome of type 2 diabetes mellitus 2 years postoperatively (P < 0.05), while sex, age at operation, duration of diabetes, anti-diabetes treatment method, preoperative body mass index, preoperative fasting blood glucose level, and preoperative diabetes control were not (P > 0.05). The rate of remission and improvement was significantly different at 1, 6, 12, and 24 months postoperatively in the Billroth I group (P < 0.05), but not in the Billroth II group (P > 0.05). CONCLUSIONS: Patients with concurrent gastric cancer and type 2 diabetes can exhibit remission of diabetes after gastrectomy. Total gastrectomy with Roux-en-Y reconstruction was associated with the highest remission rate, while distal gastrectomy with Billroth I reconstruction showed a variable rate of remission and improvement postoperatively.

[Centralization on fewer surgeons--an example from gastric surgery]. / Centralisering på den enkelte kirurg--et eksempel fra ventrikelkirurgi.

INTRODUCTION: Previous studies have shown an association between surgical volume and a decreased mortality rate for departments as a whole as well as for individual surgeons. The background for this study was to investigate whether it would be beneficial to centralize gastric surgery, not only in fewer departments but also in fewer hands in the department. MATERIALS AND METHODS: The study was based on the patient records of the 93 patients operated between 1 January 2000 and 1 September 2005. The surgeons were divided into two groups based on whether they had performed more than 15 or less than 5 operations during the period. RESULTS: Of the 93 operations, 3 surgeons performed 80 and 7 surgeons performed the remaining 13 operations. The mortality was significantly increased in patients operated by surgeons with a low operation volume, p = 0.0004. The 12 acute operations were performed as often by a surgeon with low operation volume as by a surgeon with high operation volume. Again, mortality increased when the operation was performed by a surgeon with low operation volume, p = 0.015. CONCLUSION: The results argue for a centralization of gastric resections on a few surgeons and for an organisation of acute surgery so that these procedures are performed by only a few experienced surgeons.

Factors influencing the volume-outcome relationship in gastrectomies: a population-based study.

BACKGROUND: A relationship between hospital procedural volume and patient outcomes has been observed in gastrectomies for primary gastric cancer, but modifiable factors influencing this relationship are not well elaborated. METHODS: We performed a population-based study of 1864 patients undergoing gastrectomy for primary gastric cancers at 214 hospitals. Hospitals were stratified as high-, intermediate-, or low-volume centers. Multivariate models were constructed to evaluate the effect of institutional procedural volume and other hospital- and patient-specific factors on the risk of in-hospital mortality, adverse events, and failure to rescue, defined as mortality after an adverse event. RESULTS: High-volume centers attained an in-hospital mortality rate of 1.0% and failure-to-rescue rate of .7%, both less than one-fifth of that seen at intermediate- and low-volume centers, although adverse event rates were similar across the three volume tiers. In multivariate modeling, treatment at a high-volume hospital decreased the odds of mortality (odds ratio [OR], .22; 95% confidence interval [95% CI], .05-.89), whereas treatment at an institution with a high ratio of licensed vocational nurses per bed increased the odds of mortality (OR, 1.96; 95% CI, 1.04-3.75). Being treated at a hospital with a greater than median number of critical care beds decreased odds of mortality (OR, .46; 95% CI, .25-.81) and failure to rescue (OR, .53; 95% CI, .29-.97). CONCLUSIONS: Undergoing gastrectomy at a high-volume center is associated with lower in-hospital mortality. However, improving the rates of mortality after adverse events and reevaluating nurse staffing ratios may provide avenues by which lower-volume centers can improve mortality rates.

Malignant disease in peptic ulcer surgery patients after long term follow-up: a cohort study of 1992 patients.

AIMS: To assess the effect of previous peptic ulcer surgery on subsequent malignant events, in particular in relation to previous vagotomy, a historical cohort study was conducted. METHODS: All patients undergoing surgery for peptic ulcer disease with accurate follow-up data at a large peptic ulcer clinic in the Western Infirmary, Glasgow, from 1965 to 1983 were assessed. All cancer events and specific cancer events (gastric, bronchial, laryngeal, colorectal, bladder, breast, prostate, pancreas, kidney, oesophageal cancers) were determined as outcome measures and expressed as standardised incidence ratio (SIR). RESULTS: Vagotomy and drainage accounted for 67% of all procedures for peptic ulcer disease. Eighty-three percent were habitual smokers. For all peptic ulcer surgery patients, the SIR for all cancer events was 0.86. For specific cancers, the SIRs were bronchial cancer (SIR 1.13); laryngeal cancer (SIR 2.17), colorectal cancer (SIR 0.67). For vagotomised patients the risk of gastric cancer was significantly elevated (SIR 1.50). CONCLUSIONS: An excess of cancers attributable to smoking have been found in peptic ulcer surgery patients. Vagotomised patients have a higher risk of gastric cancer after long term follow-up. This finding may have implications for screening and the safety of long term acid suppression with agents such as proton pump inhibitors.

Morbilidad y mortalidad por gastroenteroanastomosis en cáncer gástrico avanzado / Morbility and mortality related to gastroenteroanastomosis for avanced gastric cancer

OBJETIVO: Determinación de la morbilidad y mortalidad post operatorias de la gastroenteroanastomosis en pacientes con cáncer gástrico avanzado. DISEñO DEL ESTUDIO: Revisión retrospectiva de las historias clínicas de todos los pacientes con cáncer gástrico obstructivo distal sometidos a gastroenteroanastomosis en el Instituto de Enfermedades Neoplásicas entre 1980 y 1993. Se analizaron: edad, sexo, hemoglobina, albúmina, riesgo quirúrgico, ascitis, extensión de enfermedad, tiempo operatorio, estancia hospitalaria, morbilidad y moratalidad post operatorias. RESULTADOS: Se realizaron 198 gastroenteroanastomosis con una morbilidad y mortalidad del 20 por ciento y 10 porciento, respectivamente. La neumonía fue la principal causa de morbilidad y mortalidad post operatorias. El riesgo quirúrgico elevado (3-4), la invasión tumoral a órganos vecinos y la presencia de la metástasis peritoneal demostraron ser factores asociados con mayor morbilidad postoperatoria (p<0.05). El único factor de pronóstico de mortalidad postoperatoria fue el riesgo quirúrgico elevado (p<0.01). CONCLUSIONES: Debido a la elevada morbimortalidad post operatoria, la gastroenteroanastomosis no debe realizarse en pacinetes con cáncer gástrico avanzado y riesgo quirúrgico alto
