Surgeon Henry Tonks and the blur of artistry.

The professional career of 20th Century British surgeon and artist Henry Tonks provides a unique perspective into the complex balance of technique, creativity, and empathy necessary to heal both body and soul. For Tonks, the skills of surgery did not suffice to address his intense emotional attachment to his suffering patients. For that reason, he turned to painting as an expression of deeper efforts to demonstrate human suffering to which he was so sensitive and which engulfed him at times in the tragedies of mankind. Nevertheless, his appreciation of the fine details of surgery and surgical manipulations of the body never diminished. His anatomic sketches proved invaluable in reconstructive surgery. Yet, his preference remained to display the entire dimensions of his world through brush and colors. In the process, concern for the personal imperfections of both of his chosen professions enabled Tonks to continually analyze his artistry and to instill that same discipline in his students. This, too, made him a revered teacher and effective interpreter of humanism.

Alexis Carrel and His Voyage of Discovery: Miracles and the Spirituality of Healing.

In the era of positivism and anticlericalism of France's Belle Époque, scientist Alexis Carrel stood in stark contrast as one preoccupied with his faith and its relation to scientific scrutiny. Despite his early adult agnosticism, he sought proof of the divine and chose verification of the miraculous cures reported from the shrine at Lourdes, France. It so happened that on his first visit there, he encountered a truly remarkable "cure" of a young woman in the terminal stages of tubercular peritonitis. On a return visit, for the second time, he witnessed the restoration of sight to a blind child. Throughout the rest of his life, Carrel was struck by the proximity of the supernatural to corporeal interactions. He ultimately found a place for his faith as a parallel pathway and not in juxtaposition to the scientific. This paper chronicles Carrel's evolution of belief and reconciliation of faith and science.

Operative versus non-operative management in the care of patients with complicated appendicitis.

BACKGROUND: The approach to complicated appendicitis is unclear. We have sought to determine factors which may persuade surgeons to non-operative management and whether such treatment affects outcome. METHODS: All adult patients admitted over a five-year period 2009-2014 with a diagnosis of appendicitis were reviewed. Patients were grouped into uncomplicated and complicated presentations and stratified by age, gender, ethnicity, socio-economic status, and time to presentation. Mortality, morbidity, length of hospital stay (LOS), readmission, and hospital charges were used as outcome measures. RESULTS: 611 adult patients were admitted with the diagnosis of appendicitis. Of those 306 patients presented in an uncomplicated manner, and 305 patients were complicated presentations. Selection for non-operative management was significantly correlated with older age and a longer time to presentation. For outcome patients who underwent early surgery experienced a longer LOS (5.8 ± 4.4 days versus 3.4 ± 4.5 days, p < 0.0001), and more readmissions. CONCLUSION: Surgical treatment of patients presenting with complicated appendicitis is preferable to non-operative, antibiotic oriented treatment in reduction of LOS and need for readmissions.

Failure events in transition of care for surgical patients.

BACKGROUND: Unexpected clinical deterioration (failure events) in surgical patients on standard nursing units (WARDs) could have a significant impact on eventual survival. We sought to investigate failure events requiring intensive care (surgical ICU [SICU]) transfer of surgical patients on WARDs in a single-center academic setting. STUDY DESIGN: Surgical patients admitted to WARDs over a 12-month period, who developed failure events, were retrospectively reviewed. Time to deterioration since WARD arrival, clinical factors, notification chain, and outcomes were identified. A physician review panel determined the preventability of failure events. RESULTS: Ninety-eight patients experienced 111 failure events requiring SICU transfer. Most patients (85%) were emergency admissions. Of 111 events, 90% had been previously discharged from an SICU or a postanesthesia care unit (PACU). Recognition of failure was by nursing (54%) and on routine physician rounds (34%). Rapid response or code blue alone was less common (12%). A second physician notification was needed in 29%, with delays due to failure to identify severity of illness. Most commonly, respiratory events prompted notification (77 of 111, 69%). Overall mortality was 26 of 98 (27%). Median time to failure was 2 days and was associated with early transfer from the SICU or PACU. Rapid response or code blue activation was associated with higher mortality than physician notification. CONCLUSIONS: Patients most at risk for WARD failures were those with acute surgical emergencies or recently discharged from the SICU or PACU. Respiratory complications were the most common cause of WARD failure events. Many early failures may have been due to premature transfer from the SICU or PACU. Failure events on WARDs can have lethal consequences. Awareness, monitoring, and communication are important components of preventative measures.

Ton That Tung's livers.

Born in the early 20th century, the Vietnamese surgeon Ton That Tung received his medical education in French colonial Indochina at the fledgling l'Ecole de Médecine de Hanoi, the first indigenous medical school in Southeast Asia. The benefactor of a postgraduate position at the medical school, Ton That Tung subsequently obtained his surgical training at the Phù Doãn Hospital in Hanoi and concurrently developed a passion for the study of liver anatomy, pathology, and surgery. His contributions to an understanding of liver anatomy based on meticulous dissection of autopsy specimens antedated and rivaled later work by the famous Western anatomists Couinaud, Healey, Schroy, and others. Ton That Tung's contributions, however, were overshadowed by the intense national struggles of the Vietnamese to establish independent rule and self-governance from the French and by eventual alignment with eastern bloc Communist countries, thus isolating much of his work behind the "Iron Curtain" until well after the end of the Cold War. Nevertheless, Ton That Tung remains a pioneer in liver anatomy and liver surgery. His commitment to surgical science and, more importantly, to the Vietnamese people stands as a tribute to the tireless pursuit of his ideals.

Cause of death from liver metastases in colorectal cancer.

BACKGROUND: Surgically directed therapy for liver metastases from colorectal cancer (CRC) has received substantial attention in the literature as a major focus of treatment for metastatic CRC. It is presumed, but not proven, that liver metastases are a major threat to life. This study examined the course of a cohort of consecutive patients who died with CRC to determine the role played by the presence of liver metastases. METHODS: This is single-institution retrospective observational study involved all patients who died of CRC. Records were examined and imaging studies reviewed to determine the extent of liver and extrahepatic metastases in these patients. Overall survival in patients with and without liver metastases and those in whom liver metastases were thought to contribute to death was determined. RESULTS: After patient exclusions, the study population totaled 121 patients. There were 75 patients (62%) with liver metastases at death. In 40 of 75 (53%) patients, the liver metastases contributed to the patients' death. In 46 of 121 patients (38%), metastatic disease did not include liver metastases. Overall survival in patients with and without liver metastases (median survival 12 vs. 8.5 months, p = 0.089) and in those whose liver metastases did or did not contribute to death (median survival 11.5 vs. 14 months, p = 0.361) was not significant. CONCLUSIONS: The presence of liver metastases seemed to contribute to death in approximately half of the study patients, although there did not appear to be a survival disadvantage in these patients.

Evaluation and treatment of gastric stimulator failure in patients with gastroparesis.

OBJECTIVE: This study evaluates treatment of gastroparesis patients refractory to gastric electrical stimulation (GES) therapy with surgical replacement of the entire GES system. SUMMARY BACKGROUND DATA: Some patients who have symptomatic improvement with GES later develop recurrent symptoms. Some patients improve by simply altering pulse parameter settings. Others continue to have symptoms with maximized pulse parameters. For these patients, we have shown that surgical implantation of a new device and leads at a different gastric location will improve symptoms of gastroparesis. METHODS: This study evaluates 15 patients with recurrent symptoms after initial GES therapy who subsequently received a second GES system. Positive response to GES replacement therapy is evaluated by symptoms scores for vomiting, nausea, epigastric pain, early satiety, and bloating using a modified Likert score system, 0 to 4. RESULTS: Total symptom scores improved for 12 of 15 patients with GES replacement surgery. Total score for the replacement group decreased from 17.3 ± 1.6 to 13.6 ± 3.7 with a difference of 3.6 (P value = .017). This score is compared with that of the control group with a preoperative symptom score of 15.8 ± 3.6 and postoperative score of 12.3 ± 3.5 with a difference of 3.5 (P value = .011). The control group showed a 20.3% decrease in mean total symptoms score, whereas the study group showed a 22.5% decrease in mean with an absolute reduction of 2.2. CONCLUSION: Reimplantation of a GES at a new gastric location should be considered a viable option for patients who have initially failed GES therapy for gastroparesis.

Caution in interpretation of the tumor marker CA 19.9 in patients with obstructive jaundice: illustrative case reports.

BACKGROUND: Carbohydrate antigen (CA) 19.9 is a Lewis blood group oligosaccharide antigen which exists in fixed and soluble forms. The CA 19.9 antigen is synthesized by epithelial cells of the gastrointestinal tract, pancreatic duct, and biliary tree. The CA 19.9 antigen is commonly used as a tumor marker for malignancies of the pancreas and biliary tract. High levels (> 300 U/ml) of antigen have strongly suggested malignant processes. METHODS: Four patients are described with markedly elevated levels of CA 19.9 due to benign calculous disease. RESULTS: Three of four patients underwent endoscopic stone removal followed by cholecystectomy; the fourth patient spontaneously passed stones and had a subsequent cholecystectomy with benign inflammatory pathology. Removal or passage of the obstructing stones produced normalization of the CA 19.9 in each case even with long-term follow-up up to one year. All pathology specimens were interpreted as benign. CONCLUSIONS: Marked elevations of CA 19.9 may be found in benign obstructive disease and should be interpreted with caution until biliary obstruction is relieved.

Long-term effects of gastric stimulation on gastric electrical physiology.

INTRODUCTION: This study evaluates the modeling of gastric electrophysiology tracings during long-term gastric electrical stimulation for gastroparesis. We hypothesized that serosal electrogastrogram may change over time representing gastric remodeling from gastric stimulation. PATIENTS: Sixty-five patients with gastroparesis underwent placement of gastric stimulator for refractory symptoms. Mean age at initial stimulator placement was 44 years (range, 8-76), current mean age was 49, and the majority of the subjects were female (n = 51, 78 %). Only a minority had diabetes-induced gastroparesis (n = 16, 25 %); the remainder were either idiopathic or postsurgical. METHODS: At the time of stimulator placement, electrogastrogram was performed after the gastric leads were placed but before stimulation was begun. Patients underwent continuous stimulation until pacer batteries depleted. At the time of replacement, before the new pacemaker was attached, electrogastrogram was again performed. RESULTS: After a mean of 3.9 years of stimulation therapy, the mean of baseline frequency before stimulation therapy was 5.06 cycles/min and declined to 3.66 after replacement (p = 0.0000002). The mean amplitude was 0.33 mV before stimulation therapy and decreased to 0.31 mV (p = 0.73). The frequency/amplitude ratio was 38.4 before stimulation therapy and decreased to 21.9 (p = 0.001). CONCLUSION: Long-term gastric electrical stimulation causes improvement in basal unstimulated gastric frequency to near normal.

Ectopic liver masquerading as a floating intracaval mass.

Ectopic liver is defined as liver parenchyma situated outside the liver proper with no connection to native hepatic tissue. This rare developmental anomaly is most commonly described as an attachment to the gallbladder with an incidence <0.3%, but it has been reported in other locations within the abdomen and thorax.(2-4) Most cases are found incidentally in asymptomatic patients, but ectopic liver has been known to cause visceral or vascular obstruction.(4,5) Herein we present a unique case of ectopic liver attached by a thin stalk seemingly floating in the suprahepatic inferior vena cava.

The effect of resident duty hour restriction on trauma center outcomes in teaching hospitals in the state of Pennsylvania.

BACKGROUND: Resident duty hour restriction was instituted to improve patient safety, but actual impact on patient care is unclear. We sought to determine the effect of duty hour restriction on trauma outcomes in Level I trauma centers (TCs; surgery residency programs) versus Level II TCs (those with no surgery residency programs) within the state of Pennsylvania, using noninferiority as our hypothesis testing. METHODS: Outcomes (mortality and length of stay [LOS]) were compared in Level II TCs without surgery residencies (n = 7) with Level I TCs (with surgery residencies; n = 14) PRE80 (2001-2003) and POST80 (2004-2007). The subcategories of critically injured patients, Injury Severity Score (ISS) >15, ISS >25, Trauma and Injury Severity Score (TRISS) ≤ 50, Abbreviated Injury Scale (AIS) head/chest/abdomen score >3, age >65 years, mechanism, and shock, functioned as outcome predictors. RESULTS: There was a decrease in mortality overall PRE80 to POST80 for Level I and II TCs. There was a decrease in mortality in Level I TCs POST80 in ISS >15 (16.5% vs. 14.8%, p = 0.0001), AIS (head) score >3 (20.8% vs. 17.8%, p < 0.0001), age >65 years (12.2% vs. 10.7%, p = 0.0013), and blunt mechanism (5.2% vs. 4.6%, p = 0.0004). LOS was reduced in ISS >15, AIS (head) score >3, age >65 years, and penetrating mechanism in Level I TCs POST80. A similar but more profound decrease was also seen in Level II TCs PRE80 and POST80 (ISS >15, 25; AIS (head) score; shock; blunt mechanism; and TRISS ≤ 50). Testing for inhomogeneity identified less-severely injured patients at Level II TCs POST80 compared with Level I TCs in certain subcategories (ISS >15, 25; AIS (head) score; shock; blunt mechanism; and TRISS ≤ 50) regarding mortality and LOS (TRISS >50%). CONCLUSIONS: Decreases in mortality and LOS during the study periods were likely not related to resident work hour restriction but rather to overall improvement in outcomes seen at Level II (no residents) and Level I (residents) TCs. Resident work hour restrictions had no discernible effect on patient care (noninferiority).

Pancreas cancer in Mississippi: present challenges and future directions.

Pancreatic cancer remains a deadly disease. Currently, the only hope for cure is surgical resection at an early stage of the disease. However, there is evidence that many individuals do not receive this treatment, perhaps because of health care disparities. Mississippi, because of its socioeconomic composition, has been the focus of concern for health care disparities. In order to determine whether such disparities exist in Mississippi for pancreatic cancer, a retrospective analysis was done from 2000 2006 of case diagnosis, treatment, and mortality from this disease. The Mississippi Cancer Registry, the American College of Surgeons (ACS) National Cancer Data Base (NCDB), and the National Cancer Institute (NCI) Surveillance Epidemiology and End Results (SEER) program were surveyed. Outcomes at all 12 ACS Commission on Cancer (CoC) accredited hospitals within the state were compared to the NCDB nationwide (n=1331 hospitals). In 2006 Mississippi had the highest death rate from pancreas cancer in the nation (12.7/100,000). Age-adjusted incidence by county ranged to a high of 26.91/100,000. Fifty-one percent of patients who died from pancreatic cancer in the state were treated at ACS CoC hospitals. The fate of the other 49% is not known. Of the patients tracked at CoC hospitals, there was essentially no significant difference with respect to age distribution, stage at diagnosis, or first treatment modalities when compared to NCDB nationwide CoC data. There were fewer patients surviving two years with locally advanced disease compared to national figures. Of concern was the large number of patients whose treatment for pancreatic cancer is unknown. It is incumbent on health care providers in the state to develop a system of care for pancreatic cancer that is accessible, inclusive, and comprehensive.

First echelon hospital care before trauma center transfer in a rural trauma system: does it affect outcome?

BACKGROUND: Rural trauma has been associated with higher mortality because of a number of geographic and demographic factors. Many victims, of necessity, are first cared for in nearby hospitals, many of which are not designated trauma centers (TCs), and then transferred to identified TCs. This first echelon care might adversely affect eventual outcome. We have sought to examine the fate of trauma patients transferred after first echelon hospital evaluation and treatment. METHODS: All trauma patients transferred (referred group) to a Pennsylvania Level I TC located in a geographically isolated and rural setting during a 68-month period were retrospectively compared with patients transported directly to the TC (direct group). Outcome measures included mortality, complications, physiologic parameters on arrival at the TC, operations within 6 hours of arrival at the TC, discharge disposition from the TC, and functional outcome. Patients with an injury severity score <9 and those discharged from the TC within 24 hours were excluded. RESULTS: During the study period, 2,388 patients were transported directly and 529 were transferred. Mortality between groups was not different: 6% (referred) versus 9% (direct), p = 0.074. Occurrence of complications was not different between the two groups. Physiologic parameters (systolic blood pressure, heart rate, and Glasgow Coma Scale score) at admission to the Level I TC differed statistically between the two groups but seemed near equivalent clinically. Sixteen percent of patients required an operative procedure within 6 hours in the direct group compared with 10% in the referral group (p = 0.001). Hospital and intensive care unit length of stay were less in the referred group, although this was not statistically significant. Performance scores on discharge were equivalent in all categories except transfer ability. Time from injury to definitive care (TC) was 1.6 hours ± 3.0 hours in the direct group and 5.3 hours ± 3.8 hours in the referred group (p < 0.0001). The most common procedure performed at first echelon hospitals was airway control (55% of referred patients). CONCLUSIONS: In this rural setting, care at first echelon hospitals, most (95%) of which were not designated TCs, seemed to augment, rather than detract from, favorable outcomes realized after definitive care at the TC.

Combat Wound Initiative program.

The Combat Wound Initiative (CWI) program is a collaborative, multidisciplinary, and interservice public-private partnership that provides personalized, state-of-the-art, and complex wound care via targeted clinical and translational research. The CWI uses a bench-to-bedside approach to translational research, including the rapid development of a human extracorporeal shock wave therapy (ESWT) study in complex wounds after establishing the potential efficacy, biologic mechanisms, and safety of this treatment modality in a murine model. Additional clinical trials include the prospective use of clinical data, serum and wound biomarkers, and wound gene expression profiles to predict wound healing/failure and additional clinical patient outcomes following combat-related trauma. These clinical research data are analyzed using machine-based learning algorithms to develop predictive treatment models to guide clinical decision-making. Future CWI directions include additional clinical trials and study centers and the refinement and deployment of our genetically driven, personalized medicine initiative to provide patient-specific care across multiple medical disciplines, with an emphasis on combat casualty care.
