Effects of ketorolac on complications and postoperative pancreatic fistula in patients undergoing pancreatectomy.

BACKGROUND: There are conflicting data on the risk of postoperative pancreatic fistula (POPF) associated with postoperative NSAID use. The primary objective of this multi-center retrospective study was to assess the relationship between ketorolac use and POPF. The secondary objective was to assess for effect of ketorolac use on overall complication rate. METHODS: Retrospective chart review of patients undergoing pancreatectomy from January 1, 2005-January 1, 2016 was performed. Data on patient factors (age, sex, comorbidities, previous surgical history etc.), operative factors (surgical procedure, estimated blood loss, pathology etc.), and outcomes (morbidities, mortality, readmission, POPF) were collected. The cohort was compared based on ketorolac use. RESULTS: The study included 464 patients. Ninety-eight (21%) patients received ketorolac during the study period. Ninety-six (21%) patients were diagnosed with POPF within 30 days. There was a significant association between ketorolac use and clinically relevant POPF (21.4 vs. 12.7%) (p = 0.04, 95% CI [1.76, 1.04-2.97]). There was no significant difference in overall morbidity or mortality between the groups. DISCUSSION: Though there was no overall increase in morbidity, there was a significant association between POPF and ketorolac use. The use of ketorolac after pancreatectomy should be judicious.

Regional abdominal wall nerve block versus epidural anesthesia after hepatectomy: analysis of the ACS NSQIP database.

BACKGROUND: The aim of this study is to determine whether regional abdominal wall nerve block is a superior to epidural anesthesia (EA) after hepatectomy. METHODS: Patients undergoing open hepatectomy in the NSQIP targeted file (2014-2016) were identified. Those with INR > 1.5, Platelets < 100, bleeding disorders, undergoing liver ablation without resection, and spinal anesthesia were excluded. Patients with regional abdominal wall nerve block (RAB), mostly transversus abdominis plane (TAP) block, were matched (1:1) to those undergoing EA using propensity scores to adjust for baseline differences. RESULTS: Out of 1727 patients who met our inclusion criteria, 361 (21%) had RAB. Of whom 345 were matched (1:1) to those who underwent EA. The matched cohort was well-balanced regarding preoperative characteristics, extent of hepatectomy, concurrent ablations as well as biliary reconstruction. RAB was associated with shorter hospital stay (median: 6 days vs. 5 days, p = 0.007). Overall morbidity (44.1% vs. 39.4%, p = 0.217), serious morbidity (27% vs. 25.2%, p = 0.603), and mortality (2.6% vs. 2.3%, p = 0.806) were not different between the two groups. Individual complications, readmission rate, and blood transfusion were not different between the two groups. CONCLUSION: Regional abdominal nerve block is associated with shorter hospital stay than epidural anesthesia without an increase in overall postoperative morbidity or mortality. RAB is a viable alternative anesthesia adjunct to EA in patients undergoing hepatectomy. However, given the retrospective nature of this study further studies comparing the modalities should be considered to definitively define the utility of RAB.

Friend or foe? Feeding tube placement at the time of pancreatoduodenectomy: propensity score case-matched analysis.

BACKGROUND: The role of concomitant gastrostomy or jejunostomy feeding tube (FT) placement during pancreatoduodenectomy (PD) and its impact on patient outcomes remain controversial. METHODS: NSQIP database was surveyed for patients undergoing PD between 2014 and 2017. FT placement was identified using CPT codes. Propensity scores were used to match the two groups (1:1) on baseline characteristics and intraoperative variables including pancreas specific ones (duct size, gland texture, underlying disease, wound class, use of wound protector, drain placement, type of pancreatic reconstruction and vascular reconstruction). Outcomes were compared. Finally, a subset analyses for patients with delayed gastric emptying (DGE) or postoperative pancreatic fistula (POPF) were performed. RESULTS: Out of 15,224 PD, 1,104 (7.5%) had FT. POPF and DGE rates were 17% and 18%, respectively, for the entire cohort. Feeding jejunostomy was the most placed FT (88.2%). Patients with FT placement were more likely to be older (mean, 65.8 vs. 64.6 y), smokers (22.6% vs. 17.8%) who had preoperative weight loss (22.5% vs. 15.3%), ASA class ≥ 3 (80.8% vs. 77.5%), preoperative transfusion (1.5% vs. 0.84%), chemotherapy (22.8% vs. 17.5%), and radiation (14.5% vs. 6.8%, p < 0.05). The matched cohort included 880 patients in each group with completely balanced preoperative and intraoperative characteristics. In the matched cohort, patients with FT placement had higher overall morbidity (52.2% vs. 44.3%, p = 0.001), major morbidity (28.4% vs. 22.5%, p = 0.004), organ/space infection (14.4% vs. 10.9%, p = 0.026), re-operation (8.6% vs. 5.1%, p = 0.003), DGE (26.8% vs. 16.4%, p < 0.001), and longer mean hospital length of stay (12.9 vs. 11.2 days, p = 0.001) than those without FT. There was no difference in mortality (1.7% vs. 2.2%, p = 0.488) or readmission rate (20.2% vs. 17.2%, p = 0.099). In patients with DGE and POPF, FT placement was not associated with morbidity, mortality, length of stay, or readmission rate (p > 0.05). CONCLUSION: Patients with FT placement during PD tend to have higher postoperative morbidity and delayed recovery.

Use of primary surgical drains in synchronous resection for colorectal liver metastases: a NSQIP analysis of current practice paradigm.

BACKGROUND: There are no studies examining the use of subhepatic drains after simultaneous resection of synchronous colorectal liver metastases (sCRLM). This study aimed to (1) describe the current practices regarding primary drain placement, (2) evaluate drain efficacy in mitigating postoperative complications, and (3) determine impact of drain maintenance duration on patient outcomes. METHODS: The ACS-NSQIP targeted data from 2014 to 2017 were analyzed. Propensity score of surgical drain versus no drain cohorts was performed. Main study outcomes were mortality, major morbidity, organ/space surgical site infection (SSI), secondary drain/aspiration procedure, and any septic events. Additional univariate/multivariate logistic analyses were performed to identify associations with drain placement and duration. Major hepatectomy was defined as formal right hepatectomy and any trisectionectomy. RESULTS: 584 combined liver and colorectal resection (CRR) cases were identified. Open partial hepatectomy with colectomy was the most common procedure (70%, n = 407). Nearly 40% of patients received surgical drains (n = 226). Major hepatectomy, lower serum albumin, and no intraoperative portal vein occlusion (Pringle maneuver) were significantly associated with drain placement (p < 0.05). In the matched cohort (n = 190 in each arm), patients with surgical drains experienced higher rates of major morbidity (30% vs 12%), organ/space SSI (16% vs 6%), postoperative drain/aspiration procedures (9% vs 3%), and sepsis/septic shock (12% vs 4%) (all p < 0.05). Patients with severely prolonged drain removal, defined as after postoperative day 13 (POD13), had higher risk of postoperative morbidity compared to those with earlier drain removal (p < 0.01). 30-day mortality rate was not significantly different between the two groups. CONCLUSION: Primary surgical drains were placed in a substantial percentage of patients undergoing combined resection for sCRLM. This case-matched analysis suggested that surgical drains are associated with an increase in postoperative morbidity. Postoperative drain maintenance past 13 days is associated with worse outcomes compared to earlier removal.

Risk Prediction Models for Head and Neck Cancer in the US Population From the INHANCE Consortium.

Head and neck cancer (HNC) risk prediction models based on risk factor profiles have not yet been developed. We took advantage of the large database of the International Head and Neck Cancer Epidemiology (INHANCE) Consortium, including 14 US studies from 1981-2010, to develop HNC risk prediction models. Seventy percent of the data were used to develop the risk prediction models; the remaining 30% were used to validate the models. We used competing-risk models to calculate absolute risks. The predictors included age, sex, education, race/ethnicity, alcohol drinking intensity, cigarette smoking duration and intensity, and/or family history of HNC. The 20-year absolute risk of HNC was 7.61% for a 60-year-old woman who smoked more than 20 cigarettes per day for over 20 years, consumed 3 or more alcoholic drinks per day, was a high school graduate, had a family history of HNC, and was non-Hispanic white. The 20-year risk for men with a similar profile was 6.85%. The absolute risks of oropharyngeal and hypopharyngeal cancers were generally lower than those of oral cavity and laryngeal cancers. Statistics for the area under the receiver operating characteristic curve (AUC) were 0.70 or higher, except for oropharyngeal cancer in men. This HNC risk prediction model may be useful in promoting healthier behaviors such as smoking cessation or in aiding persons with a family history of HNC to evaluate their risks.

Adjuvant Chemotherapy Does Not Improve Recurrence-Free Survival in Patients With Stage 2 or Stage 3 Rectal Cancer After Neoadjuvant Chemoradiotherapy and Total Mesorectal Excision.

BACKGROUND: Current guidelines for locally advanced stage 2/3 rectal cancer recommend neoadjuvant chemoradiotherapy followed by total mesorectal excision and adjuvant chemotherapy. The oncologic benefit of adjuvant chemotherapy has not been consistently demonstrated. OBJECTIVE: The purpose of this study was to evaluate disease recurrence and survival in patients with rectal cancer who received adjuvant chemotherapy after chemoradiotherapy and total mesorectal excision. DESIGN: This was a retrospective review of patients with stage 2/3 rectal cancer after chemoradiotherapy and surgery, based on receipt of adjuvant chemotherapy. SETTINGS: The study was conducted at the Kaiser Permanente Southern California system of 14 hospitals and associated clinics. PATIENTS: A total of 862 patients with stage 2/3 rectal cancer diagnosed and treated between January 1, 2005, and December 31, 2016, were included in this study. INTERVENTIONS: The study involved neoadjuvant chemoradiotherapy followed by total mesorectal excision with or without adjuvant chemotherapy. MAIN OUTCOME MEASURES: The primary end point was recurrence-free survival. RESULTS: A total of 348 stage 2 and 514 stage 3 patients were included; 660 patients (76.6%) underwent adjuvant chemotherapy. Mean patient follow-up after surgery was 63.0 months (range, 3-160). Multivariable analysis showed that yp stage (HR for yp stage 2 = 4.74; yp stage 3 = 8.83) and en bloc resection (HR = 1.76) were the only variables that significantly predicted disease recurrence. Neither pretreatment tumor stage nor receipt of adjuvant chemotherapy was significantly associated with recurrence-free survival. Log-rank testing failed to demonstrate significant recurrence-free survival improvement after receipt of adjuvant chemotherapy in any patient subgroup. LIMITATIONS: The study was limited by selection bias attributed to the nature of a retrospective study without patient randomization or predefined treatment protocol. CONCLUSIONS: In stage 2/3 rectal cancer treated with chemoradiotherapy and surgery, the addition of adjuvant chemotherapy was not associated with decreased recurrence-free survival in the entire cohort or in any subgroup, whereas tumor response to chemoradiotherapy is closely associated with disease recurrence. These findings have important consequences for treatment and surveillance decisions for patients with rectal cancer. Presurgical efforts that maximize tumor downstaging, such as total neoadjuvant therapy, may produce better oncologic outcomes than traditional adjuvant chemotherapy.

LA QUIMIOTERAPIA ADYUVANTE NO MEJORA LA SOBREVIDA LIBRE DE RECURRENCIA EN PACIENTES CON CÁNCER DE RECTO ESTADÍOS II O III DESPUÉS DE RADIO-QUIMIOTERAPIA NEOADYUVANTE Y ESCISIÓN TOTAL DEL MESORRECTO: Las guías actuales para el tratamiento de cáncer rectal en estadio II-III localmente avanzado, recomiendan la radio-quimioterapia neoadyuvante con escisión total del mesorrecto seguidas de quimioterapia adyuvante. El beneficio oncológico de la quimioterapia adyuvante no ha sido demostrado de manera fehaciente.Evaluar la recurrencia y sobrevida a la enfermedad en pacientes con cáncer rectal que recibieron quimioterapia adyuvante después de radio-quimioterapia y escisión total del mesorrecto.Revisión retrospectiva de pacientes con cáncer rectal en estadios II-III después de radio-quimioterapia y cirugía, basada en la recepción de quimioterapia adyuvante.Sistema Permanente de Kaiser Sur-Californiano de 14 hospitales y clínicas asociadas.862 pacientes con cáncer rectal en estadio II-III diagnosticados y tratados entre el 1 de Enero 2005 y el 31 de Diciembre 2016.Radio-quimioterapia neoadyuvante seguida de escisión total del mesorrecto +/- quimioterapia adyuvante.El objetivo primario fue la sobrevida libre de recurrencia.Fueron incluidos 348 pacientes en estadio II y 514 en estadio III. 660 pacientes (76,6%) se sometieron a quimioterapia adyuvante. El seguimiento medio de cada paciente después de la cirugía fué de 63.0 meses (rango, 3-160). El análisis multivariable mostró que la etapa yp (Cociente de riesgo para estadío yp II = 4.74 y estadío yp III = 8.83) y la resección en bloque (Cociente de riesgo = 1.76) fueron las únicas variables que predijeron significativamente la recurrencia de la enfermedad. Ni el estadío tumoral previo al tratamiento ni la recepción de quimioterapia adyuvante se asociaron significativamente con la sobrevida libre de recurrencia. Las pruebas de rango logarítmico no pudieron demostrar una mejoría significativa de la sobrevida libre de recurrencia después de recibir quimioterapia adyuvante en cualquier subgrupo de pacientes.Sesgo de selección, debido al estudio retrospectivo sin aleatorización de los pacientes o protocolo de tratamiento predefinido.En casos de cáncer de recto estadíos II-III tratados con radio-quimioterapia y cirugía, la adición de quimioterapia adyuvante no se asoció con una disminución de la sobrevida libre de recurrencia en toda la cohorte o en ningún subgrupo, mientras que la respuesta tumoral a la radio-quimioterapia está estrechamente asociada con la recurrencia de la enfermedad. Estos hallazgos tienen consecuencias importantes en la decisión del tratamiento y la vigilancia en pacientes con cáncer de recto. Los esfuerzos pre-quirúrgicos que maximizan la reducción del tamaño del tumor, como la terapia neoadyuvante total, pueden producir mejores resultados oncológicos que la quimioterapia adyuvante tradicional.

Robotic versus laparoscopic elective colectomy for left side diverticulitis: a propensity score-matched analysis of the NSQIP database.

PURPOSE: Robotic surgery might have an advantage over conventional laparoscopy for colonic diverticulitis. We intend to compare both approaches in the elective management of left side diverticulitis. METHODS: The National Surgical Quality Improvement Program (NSQIP) database (2012-2014) was surveyed for patients undergoing elective left/sigmoid colectomy for diverticulitis. Patient demographics, co-morbidities, disease complexity, and intraoperative details were matched on propensity scores derived from logistic regression model. RESULTS: We identified 441 robotic and 6584 laparoscopic cases. Mean age was 56.8 years. Mean BMI was 29.5, and 46.5% of patients were males. Low preoperative albumin (< 3.5 mg/dl, 11.1% vs. 6.8%, p = 0.003), splenectomy (0.45% vs. 0.05%, p = 0.002), and enterotomy repair (1.1% vs. 0.4%, p = 0.029) were higher in the robotic group than the laparoscopic group. Hand assistance (35.8% vs. 42.9%, p = 0.003), splenic flexure takedown (41.5% vs. 49.2%, p = 0.002), and ureteric stent placement (18.6% vs. 23.5%, p = 0.017) were less common in the robotic group than the laparoscopic group. Case-matched analysis showed that robotic surgery was associated with shorter hospital stay (3.89 ± 2.18 days vs. 4.75 ± 3.25 days, p < 0.001), lower conversion rate (7.5% vs. 14.3%, p = 0.001), and longer operative time (219.2 ± 95.6 min vs. 188.8 ± 82.3 min, p < 0.001) than laparoscopic surgery. Robotic approach was associated with lower overall morbidity in multivariate analysis (OR = 0.72, 95% CI = 0.55-0.96), but not in case-matched analysis (14.4% vs. 19.2%, p = 0.058). CONCLUSIONS: Robotic surgery is associated with shorter hospital stay and lower conversion rate and may offer lower overall morbidity than laparoscopy after elective left side colectomy for diverticulitis. Controlled prospective studies are needed to confirm these findings.

Incidence, Risk Factors, and Trends of Motor Peripheral Nerve Injury After Colorectal Surgery: Analysis of the National Surgical Quality Improvement Program Database.

BACKGROUND: Motor peripheral nerve injury is a rare but serious event after colorectal surgery, and a nationwide study of this complication is lacking. OBJECTIVE: The purpose of this study was to report the incidence, trends, and risk factors of motor peripheral nerve injury during colorectal surgery. DESIGN: The National Surgical Quality Improvement Program database was surveyed for motor peripheral nerve injury complicating colorectal procedures. Risk factors for this complication were identified using logistic regression analysis. SETTINGS: The study used a national database. PATIENTS: Patients undergoing colorectal resection between 2005 and 2013 were included. MAIN OUTCOME MEASURES: The incidence, trends, and risk factors for motor peripheral nerve injury complicating colorectal procedures were measured. RESULTS: We identified 186,936 colorectal cases, of which 50,470 (27%) were performed laparoscopically. Motor peripheral nerve injury occurred in 122 patients (0.065%). Injury rates declined over the study period, from 0.025% in 2006 to <0.010% in 2013 (p < 0.001). Patients with motor peripheral nerve injury were younger (mean ± SD; 54.02 ± 15.41 y vs 61.56 ± 15.95 y; p < 0.001), more likely to be obese (BMI ≥30; 43% vs 31%; p = 0.003), and more likely to have received radiotherapy (12.3% vs 4.7%; p < 0.001). Nerve injury was also associated with longer operative times (277.16 ± 169.79 min vs 176.69 ± 104.80 min; p < 0.001) and was less likely to be associated with laparoscopy (p = 0.043). Multivariate analysis revealed that increasing operative time was associated with nerve injury (OR = 1.04 (95% CI, 1.03-1.04)), whereas increasing age was associated with a protective effect (OR = 0.80 (95% CI, 0.71-0.90)). LIMITATIONS: This study was limited by its retrospective nature. CONCLUSIONS: Motor peripheral nerve injury during colorectal procedures is uncommon (0.065%), and its rate declined significantly over the study period. Prolonged operative time is the strongest predictor of motor peripheral nerve injury during colorectal procedures. Instituting and documenting measures to prevent nerve injury is imperative; however, special attention to this complication is necessary when surgeons contemplate long colorectal procedures.

Household air pollution and lung cancer risk among never-smokers in Nepal.

More than half of the global population relies on biomass fuels (wood, charcoal, crop residue, dung) for cooking and/or heating purposes. Household air pollution (HAP) resulting from the use of these solid fuels is of particular concern, given the overall prevalence as well as the intensity of exposure and the range of potential adverse health outcomes. Long term exposure to HAP is a major public health concern, particularly among women and children in low and middle income countries. In this study, we investigated the association between exposure to HAP resulting from combustion of biomass and lung cancer risk among Nepalese population. Using a hospital-based case-control study (2009-2012), we recruited 606 lung cancer cases and 606 healthy controls matched on age (±5 years), gender, and geographical residence. We used unconditional logistic regression to compute odds ratios (ORs) and 95% Confidence Intervals (95% CI) for lung cancer risk associated with HAP exposures, adjusting for potential confounders (tobacco use, TB status, SES, age, gender, ethnicity, and exposure to second hand smoke. In our overall analysis, we observed increased risk of lung cancer among those who were exposed to HAPs (OR: 1.77, 95% CI: 1.00-3.14). A more detailed analysis stratified by smoking status showed considerably higher risk of lung cancer associated with increasing duration of exposure to HAP from biomass combustion, with evidence of a borderline exposure-response relationship (Ptrend=0.05) that was more pronounced among never-smokers (Ptrend=0.01). Our results suggest that chronic exposure to HAP resulting from biomass combustion is associated with increased lung cancer risk, particularly among never-smokers in Nepal.

Feeding Jejunostomy Tube Placed during Esophagectomy: Is There an Effect on Postoperative Outcomes?

BACKGROUND: Feeding jejunostomy (FJ) tubes are routinely placed during esophagectomy. However, their effect on immediate postoperative outcomes in this patient population is not clear. OBJECTIVES: To evaluate the effect of FJ tube placement during esophagectomy on postoperative morbidity and mortality. METHODS: The National Surgical Quality Improvement Program database was used to evaluate the effect of FJ tube placement during esophagectomy on 30-day postoperative morbidity and mortality rates. A propensity score-matched cohort was used to compare postoperative outcomes of patients with and without FJ tubes. RESULTS: An FJ tube was placed in 45% of 2059 patients undergoing esophagectomy. The anastomotic leak rate was 13.5%. Patients with FJ tubes were more likely to have preoperative radiation therapy (59.6% vs 54.9%, p = 0.041), transhiatal esophagectomy (21.5% vs 19.2%, p = 0.012), a malignant diagnosis (93.2% vs 90.4%), and longer operative time (393 min vs 348 min, p < 0.001). In a case-matched cohort, mortality (2% vs 2.4%, p = 0.618) and severe morbidity (38.2% vs 34.6%, p = 0.128) were comparable between patients with and without FJ tubes. FJ tube placement was associated with higher overall morbidity (46% vs 38.6%, p = 0.002), superficial wound infection (6.3% vs 2.9%, p = 0.001), and return to the operating room (16.7% vs 12.5%, p = 0.016). In a subgroup of patients with anastomotic leak, FJ was associated with shorter hospital stay (20.1 days vs 24.3 days, p = 0.046). CONCLUSION: These mixed findings support selective rather than routine FJ tube placement during esophagectomy.

Predictors of Failed Transcystic Laparoscopic Common Bile Duct Exploration: Analysis of Multicenter Integrated Health System Database.

BACKGROUND: The aim of this study is to report our experience with laparoscopic common bile duct exploration (LCBDE) and validate the experts' opinion about anatomical predictors of failed transcystic LCBDE (TLCBDE) approach. METHODS: Patients undergoing LCBDE at Kaiser Permanente Southern California hospitals (2005-2015) were included. Predictors of failed TLCBDE were identified using bivariate analysis. RESULTS: Of 115 LCBDE, 89.6% were TLCBDE and 10.4% through choledochotomy. Success rate, morbidity, and length of hospital stay were 83.5%, 6.1%, and 3.8 days respectively. Only stone size:cystic duct ratio >1 (35% versus 63%, P = .044) was associated with failure of TLCBDE. In accordance with experts' opinion, there was a suggestive association of stone size ≥6 mm, cystic duct ≤4 mm, multiple stones, and proximal stone location with failure; however, these did not reach statistical significance. CONCLUSION: LCBDE is an effective and safe mean of clearing common bile duct stones at community hospitals of an integrated health system. Previously cited contraindications for TLCBDE are not absolute, but rather predictors of failure.

Complex Ventral Hernias: A Review of Past to Present.

With the incidence of ventral hernias increasing, surgeons are faced with greater complexity in dealing with these conditions. Proper knowledge of the history and the advancements made in managing complex ventral hernias will enhance surgical results. This review article highlights the literature regarding complex ventral hernias, including a shift from a focus that stressed surgical technique toward a multimodal approach, which involves optimization and identification of suboptimal characteristics.

Surgical Intervention for Right-Side Diverticulitis: A Case-Matched Comparison with Left-Side Diverticulitis.

Right-side diverticulitis (RSD) is an uncommon disease in Western countries. We conducted a case-matched comparison of surgically managed right-side and left-side diverticulitis (LSD) from the Southern California Kaiser Permanente database (2007-2014). Of 995 patients undergoing emergent surgery for diverticulitis, 33 RSD (3.3%) met our inclusion criteria and were matched (1:1) to LSD based on age, gender, year of diagnosis, and Hinchey class. Mean age of the RSD group was 56 ± 13.9 years, and 24.2 per cent were Asian. RSD was classified as Hinchey class III or IV in 28.1 per cent and 9.4 per cent of cases, respectively. Right hemicolectomy was performed in 87.9 per cent and laparoscopy was used in 24.2 per cent of the cases. Surgically managed RSD patients were more likely to be Asian (25% vs 3.1%, P = 0.03) and have body mass index < 25 (31.3% vs 6.3%, P = 0.02) compared with LSD patients. Diverting stoma was less common in the RSD (6.3% vs 62.5%) (P < 0.001). Hospital stay was shorter in RSD (7.6 ± 4.2 vs 12.8 ± 9.4 days, P = 0.006) and more common in the RSD group (P < 0.01). Open surgery (90.6% vs 71.9%) and postoperative complications (37.5% vs 25%) were more common in the LSD group, but that was not statistically significant (P > 0.05). Surgery for complicated RSD was associated with shorter hospital stay and decreased likelihood of diverting ostomy.

Same-Day versus Conventional Different-Day Endoscopic Retrograde Cholangiopancreatography and Laparoscopic Cholecystectomy: A Multi-Center Retrospective Study.

Same-day endoscopic retrograde cholangiopancreatography (ERCP) and cholecystectomy (LC) could potentially reduce hospital length of stay (HLOS). Patients undergoing same-day procedures (N = 164) between 2012 and 2014 were compared with different-day procedures performed in the second half of 2014 (N = 276), in the Kaiser Permanente Southern California database. Both groups had comparable baseline characteristics. ERCP success rate (97.5% vs 93.5%), overall postoperative morbidity (3.66% vs 3.99%), and retained stones (2.5% vs 5.8%) were not different between groups (P > 0.05); however, HLOS was shorter in the same-day group (2.99 ± 2.34 vs 3.84 ± 2.52 days, P < 0.001). Morbidity, procedure success, and HLOS were not different in the same-day group, whether ERCP was performed before or after LC (P > 0.05). In the same-day group, those undergoing single anesthesia had higher BMI (40.1 ± 10.8 vs 30.3 ± 6.6) and were more likely to have gastric bypass (30% vs 0%) than those undergoing separate anesthesia sessions (P < 0.01). Longer HLOS (4.8 ± 3.5 vs 2.9 ± 2.2 days) and higher estimated blood loss (65 ± 90 mL vs 20 ± 29 mL) were also associated with the single-anesthetic session (P < 0.01). ERCP performed on the same day of LC reduces HLOS without increasing morbidity. This approach does not affect postoperative morbidity and ERCP success rate, whether ERCP was performed before or after LC.

Endostapler versus Hem-O-Lok clip to secure the appendiceal stump and mesoappendix during laparoscopic appendectomy.

BACKGROUND: Our study evaluates the safety and cost of using the Hem-O-Lok (HOL) clip in laparoscopic appendectomy (LA). METHOD: We prospectively compared 30-day postoperative outcomes and cost between HOL clip and endoscopic stapler (ES) in LA at a single institution. RESULTS: HOL clip was used in 45 out of 92 LA. Perforated appendicitis (29.8% vs. 11.1%, P = 0.027) and postoperative complications were more common in the ES group (19.2% vs. 2.2%, p = 0.009). In multivariate analysis, HOL clip was associated with lower complications rate (OR = 0.05, 95% CI 0.003-0.744; p = 0.030). In propensity score matched cohort, complications were not different (p > 0.05). In patients with non-perforated appendicitis, HOL use increased operative time by 10 min on average (p = 0.004). Minimum ES cost per single appendectomy was $273.13, while HOL clip cost was $32.14. CONCLUSION: The use of HOL clip in LA is safe and it reduced the costs of the procedure in comparison to the use of ES.

Laparoscopic common bile duct exploration versus endoscopic retrograde cholangiopancreatography for choledocholithiasis found at time of laparoscopic cholecystectomy: Analysis of a large integrated health care system database.

BACKGROUND: We compared endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic common bile duct exploration (LCBDE) for managing choledocholithiasis found at time of cholecystectomy. METHODS: One hundred and five LCBDE (2005-2015) were compared to 195 LC/ERCP (2014-2015) from the Southern California Kaiser Permanente database. RESULTS: LC/ERCP was more effective at clearing the CBD (98% vs. 88.6%, p = 0.01); but required more procedures per patient (mean ± standard deviation, 1.1 ± 0.4 vs. 2.0 ± 0.12, p < 0.001). Morbidity, hospital length of stay and readmission were not different (P > 0.05). Four patients failed ERCP, while 12 patients failed LCBDE and had subsequent ERCP (10) or CBD exploration (2). All patients with RYGB had successful LCBDE. CONCLUSION: LC/ERCP is better than LCBDE in clearing CBD stones, but has similar morbidity and is an effective alternative for patients with RYGB.

Accreditation Council for Graduate Medical Education Core Competencies at a Community Teaching Hospital: Is There a Gap in Awareness?

CONTEXT: Reports evaluating faculty knowledge of the Accreditation Council for Graduate Medical Education (ACGME) core competencies in community hospitals without a dedicated residency program are uncommon. OBJECTIVE: Faculty evaluation regarding knowledge of ACGME core competencies before a residency program is started. DESIGN: Physicians at the Kaiser Permanente Fontana Medical Center (N = 480) were surveyed for their knowledge of ACGME core competencies before starting new residency programs. MAIN OUTCOME MEASURES: Knowledge of ACGME core competencies. RESULTS: Fifty percent of physicians responded to the survey, and 172 (71%) of respondents were involved in teaching residents. Of physicians who taught residents and had complete responses (N = 164), 65 (39.7%) were unsure of their knowledge of the core competencies. However, most stated that they provided direct teaching to residents related to the knowledge, skills, and attitudes stated in each of the 6 competencies as follows: medical knowledge (96.3%), patient care (95.7%), professionalism (90.7%), interpersonal and communication skills (86.3%), practice-based learning (85.9%), and system-based practice (79.6%). Physician specialty, years in practice (1-10 vs > 10), and number of rotations taught per year (1-6 vs 7-12) were not associated with knowledge of the competencies (p > 0.05); however, full-time faculty (teaching 10-12 rotations per year) were more likely to provide competency-based teaching. CONCLUSION: Objective assessment of faculty awareness of ACGME core competencies is essential when starting a residency program. Discrepancy between knowledge of the competencies and acclaimed provision of competency-based teaching emphasizes the need for standardized teaching methods that incorporate the values of these competencies.

Does Incidental Appendectomy Increase the Risk of Complications after Abdominal Procedures?

Incidental appendectomy (IA) could potentially increase the risk of morbidity after abdominal procedures; however, such effect is not clearly established. The aim of our study is to test the association of IA with morbidity after abdominal procedures. We identified 743 (0.37%) IA among 199,233 abdominal procedures in the National Surgical Quality Improvement Program database (2005-2009). Cases with and without IA were matched on the index current procedural terminology code. Patient characteristics were compared using chi-squared test for categorical variables and Student t test for continuous variables. Multivariate logistic regression analysis was performed. Emergency and open surgeries were associated with performing IA. Multivariate analysis showed no association of IA with mortality [odds ratio (OR) = 0.51, 95% confidence interval (CI) = 0.26-1.02], overall morbidity (OR = 1.16, 95% CI = 0.92-1.47), or major morbidity (OR = 1.20, 95% CI = 0.99-1.48). However, IA increased overall morbidity among patients undergoing elective surgery (OR = 1.31, 95% CI = 1.03-1.68) or those ≥30 years old (OR = 1.23, 95% CI = 1.00-1.51). IA was also associated with higher wound complications (OR = 1.46, 95% CI = 1.05-2.03). In conclusion, IA is an uncommonly performed procedure that is associated with increased risk of postoperative wound complications and increased risk of overall morbidity in a selected patient population.

Long-term health effects among testicular cancer survivors.

PURPOSE: Testicular cancer is diagnosed at a young age and survival rates are high; thus, the long-term effects of cancer treatment need to be assessed. Our objectives are to estimate the incidence rates and determinants of late effects in testicular cancer survivors. METHODS: We conducted a population-based cohort study of testicular cancer survivors, diagnosed 1991-2007, followed up for a median of 10 years. We identified 785 testicular cancer patients who survived ≥5 years and 3323 men free of cancer for the comparison group. Multivariate Cox regression analysis was used to compare the hazard ratio between the cases and the comparison group and for internal analysis among case patients. RESULTS: Testicular cancer survivors experienced a 24 % increase in risk of long-term health effects >5 years after diagnosis. The overall incidence rate of late effects among testicular cancer survivors was 66.3 per 1000 person years. Higher risks were observed among testicular cancer survivors for hypercholesterolemia, infertility, and orchitis. Chemotherapy and retroperitoneal lymph node dissection appeared to increase the risk of late effects. Being obese prior to cancer diagnosis appeared to be the strongest factor associated with late effects. CONCLUSIONS: Testicular cancer survivors were more likely to develop chronic health conditions when compared to cancer-free men. IMPLICATIONS FOR CANCER SURVIVORS: While the late effects risk was increased among testicular cancer survivors, the incidence rates of late effects after cancer diagnosis was fairly low.
