Perioperative Transfusions in Veterans Following Noncardiac Procedures.

Background: Perioperative blood transfusions are associated with increased morbidity and mortality. Each surgical specialty is associated with unique operative variables. Moreover, transfusion rates vary across specialty. This article seeks to elucidate variables both common and unique to surgical specialties. Materials and Methods: This study was a retrospective review of 5344 patients from the prospectively maintained Veterans Affairs Surgical Quality Improvement Project at a single-level 1A tertiary Veterans Affairs Medical Center. Data collected included demographic information, preoperative clinical variables, postoperative outcomes, and perioperative transfusion (within 72 hours of procedure). Patients were stratified based on whether they received a transfusion. Univariate and multivariate analyses were performed. P values <.05 were significant. Results: Of the 5344 patients included in the study, 153 required perioperative transfusion of at least one unit of packed red blood cells. Patients who underwent transfusion were more likely to be men, have an underlying bleeding disorder, and have more preoperative risk factors. Although unique risk factors were found within most specialties, there was no statistically significant difference in postoperative complications between surgical specialties. Patients requiring transfusion had higher rates of morbidity and mortality. Elevated preoperative hematocrit was significantly protective against requiring transfusion across most specialties. Conclusions: Specialty-based differences in transfusion requirement may be due to the proportion of older and more frail patients, hospital transfusion thresholds, and surgical complexity. Hematocrit, however, could be an effective target for mitigating cost and morbidity associated with transfusion. Preoperative hematocrit optimization through B12, folate, iron dosing, and erythropoietin supplementation could be a useful strategy.

Factors Associated with Perioperative Transfusions in Veterans.

Background: Private sector literature demonstrates an association between perioperative transfusions and poor clinical outcomes. Hemostatic agents, surgeon training, and patient blood management programs (PBMPs) may mitigate perioperative bleeding. This study attempts to identify preoperative risk factors associated with perioperative transfusions in Veterans. Study Design and Methods: This study is a retrospective review of the prospectively maintained Veterans Affairs Surgical Quality Improvement Project database. Included patients were older than 18 years and underwent noncardiac surgery between April 1, 2016, and March 31, 2021. Data collected included demographics, surgery variables, preoperative clinical variables, postoperative outcomes, and perioperative transfusions. Cohorts were created based on transfusion status. Univariate and multivariate analyses were performed to characterize the similarities, differences, and potential predictors of perioperative transfusion. Results: Of 6108 patients included, 153 patients received perioperative transfusions. The risks for transfusion included older age, male sex, black race, smoking, and low body mass index (BMI). The highest percent of transfused patients underwent vascular (43.4%), orthopedic (22%), and general surgeries (20%). Transfusion increased risk for postoperative cerebral vascular accident (P = .041) and 30-day mortality (P < .001). Multivariate regression analysis revealed American Society of Anesthesiology class, chemotherapy within 30 days, increased age, tobacco smoking, and decreased BMI were predictive of perioperative transfusions. Discussion: Perioperative transfusions are associated with increased morbidity and mortality in the Veteran population. These retrospective data describe the complex relationships between perioperative transfusions and outcomes after noncardiac surgery. These results serve as a foundation to create predictive models and PBMP within the veteran population to decrease transfusion requirements and associated complications.

Laparoscopic Repair of a Right-Sided Diaphragmatic Hernia: A Technical Report.

Introduction: Occult diaphragmatic hernias after trauma are relatively rare and may present months to years after the traumatic event. Clinical presentations range from asymptomatic incidental findings on imaging to life-threatening incarceration of abdominal visceral organs. This study presents a case of a patient with a symptomatic diaphragmatic hernia secondary to a trauma >30 years prior. A literature review of this defect was performed examining the pathophysiology, presentation, and operative considerations. Case Presentation: A 58-year-old male with a history of multiple traumatic motor vehicle accidents 30 years prior presented with abdominal pain and obstructive symptoms. Axial imaging demonstrated a right-sided diaphragmatic hernia defect containing small intestine, colon, and omentum. He ultimately underwent a transabdominal laparoscopic repair of the defect with mesh buttressing. Postoperative the patient recovered well and was discharged without complications. Conclusion: Limited data outside of case reports exist for surgical management of occult diaphragmatic hernias secondary to trauma. Reported management options include open and minimally invasive thoracic as well as open and minimally invasive abdominal approaches; each with advantages and disadvantages. Depending on the defect size, both primary repair and repair with mesh reinforcement are appropriate options. More data comparing the approach and repair technique are needed to determine the best technique.

Robotic Foregut Surgery in the Veterans Health Administration: Increasing Prevalence, Decreasing Operative Time, and Improving Outcomes.

BACKGROUND: Historically, robotic surgery incurs longer operative times, higher costs, and nonsuperior outcomes compared with laparoscopic surgery. However, in areas of limited visibility and decreased accessibility such as the gastroesophageal junction, robotic platforms may improve visualization and facilitate dissection. This study compares 30-day outcomes between robotic-assisted foregut surgery (RAF) and laparoscopic-assisted foregut surgery in the Veterans Health Administration. STUDY DESIGN: This is a retrospective review of the Veterans Affairs Quality Improvement Program database. Patients undergoing laparoscopic-assisted foregut surgery and RAF were identified using CPT codes 43280, 43281, 43282, and robotic modifier S2900. Multivariable logistic regression and multivariable generalized linear models were used to analyze the independent association between surgical approach and outcomes of interest. RESULTS: A total of 9,355 veterans underwent minimally invasive fundoplication from 2008 to 2019. RAF was used in 5,392 cases (57.6%): 1.63% of cases in 2008 to 83.41% of cases in 2019. After adjusting for confounding covariates, relative to laparoscopic-assisted foregut surgery, RAF was significantly associated with decreased adjusted odds of pulmonary complications (adjusted odds ratio [aOR] 0.44, p < 0.001), acute renal failure (aOR 0.14, p = 0.046), venous thromboembolism (aOR 0.44, p = 0.009) and increased odds of infectious complications (aOR 1.60, p = 0.017). RAF was associated with an adjusted mean ± SD of 29 ± 2-minute shorter operative time (332 minutes vs 361 minutes; p < 0.001). CONCLUSIONS: Veterans undergoing RAF ascertained shorter operative times and reduced complications vs laparoscopy. As surgeons use the robotic platform, clinical outcomes and operative times continue to improve, particularly in operations where extra articulation in confined spaces is required.

Effects of Liver Pathology on Sleeve Gastrectomy Outcomes.

Introduction: Sleeve gastrectomy engenders weight loss and improves comorbidities at 1 year postoperatively. A relationship has not been established between liver pathology and diabetic outcomes and weight loss following a sleeve gastrectomy. This study evaluates the association between liver pathology and both diabetic remission and weight loss in morbidly obese veterans. Methods: A prospective database of all patients undergoing sleeve gastrectomy with simultaneous liver biopsy at a Veterans Affairs Medical Center was analyzed from 2018 through 2020. The database included patient demographics, liver biopsy pathology, laboratory values, and antihyperglycemic medications. Patient outcomes at 12 months postoperatively were analyzed specifically for diabetic resolution and weight loss. Chi-square test and Fisher's exact test were used for categorical comparisons, and one-way analysis of variance test and two-tailed t-test were used for continuous variable comparisons. Multivariate linear regression models were created to assess the association between liver pathology and changes in body mass index (BMI) and diabetic status. A two-sided P-value of 0.05 indicated significance. Results: Of the 77 patients included in the study, 70.1% of patients achieved diabetic remission at 12 months. After condensing steatosis and fibrosis scores into low- and high-grade categories, patients with no hepatic disease had significantly lower BMI at 12 months postoperatively than patients with low- or high-grade hepatic disease (29.2 ± 3.6 kg/m2 versus 35.1 ± 4.0 kg/m2 versus 34.5 ± 3.7 kg/m2, respectively, P = .009). On multivariate linear regression model, low-grade overall hepatic disease (ß = 3.1 ± 1.5; P = .043) and preoperative oral glycemic medications (ß = 2.4 ± 1.0; P = .026) were associated with a significantly increased 12-month BMI. Also, Black or African American race compared with White race was associated with a significant decrease in postoperative BMI (ß = -1.9 ± 0.8; P = .023). Conclusions: Regardless of preexisting liver disease, most diabetic patients who undergo sleeve gastrectomy experience diabetic remission at 12 months postoperatively. Additionally, patients with no underlying liver disease lose more weight than those with low- or high-grade liver disease.

Laparoscopic Intragastric Cystgastrostomy: A Technical Report.

Background: Management of symptomatic pancreatic pseudocysts poses a unique challenge to minimally invasive surgeons. Despite the predominance of endoscopic management of pancreatic pseudocysts, the laparoscopic approach remains a critical skill in the armamentarium of surgeons. Methods: This report details a laparoscopic intragastric approach to create a pancreatic cystgastrostomy using intraoperative ultrasound and endoscopy. Conclusion: Laparoendoscopic techniques for pancreatic pseudocysts are still required in selective cases when endoscopic management is not available or fails. Using this technique provides patients with same clinical benefits of an endoscopic approach.

Cholecystectomy Outcomes in the Veterans Affairs Surgical Quality Improvement Program (2006-2017).

Background: Cholecystectomy trends and outcomes have been reported extensively in the private sector. Despite being one of the most common procedures performed in the United States, there is a paucity of reports on the trends and outcomes of laparoscopic and open cholecystectomy in the veteran population. Materials and Methods: Veterans who underwent laparoscopic or open cholecystectomy from 2006 to 2017 were identified using current procedural terminology codes from the Veterans Affairs Surgical Quality Improvement Program (VASQIP) database. Multivariable analyses were used to compare laparoscopic and open outcomes. The primary outcome was mortality, and secondary outcomes were postoperative complications and length of stay (LOS). Results: In the VASQIP database, 53,901 patients underwent laparoscopic cholecystectomy and 8011 patients underwent open cholecystectomy during the study period. The laparoscopic approach increased from 82.0% (2006-2008) to 91.9% (2015-2017). Postoperatively, the open group had a significantly higher morbidity rate (15.4% versus 3.8%, P < .001). The 30-day mortality rate and mean LOS were also significantly higher in the open cholecystectomy group (P < .001). Earlier year of operation, diabetes diagnosis, and open approach significantly increased the likelihood of postoperative morbidity (P < .05). Conclusions: Similar to the private sector, minimally invasive cholecystectomy in the Veterans Health Administration (VHA) has increased over the last two decades. Diabetes was present in a significant percentage of the veteran population and was a predictor of all postoperative complications. Finally, the clinical outcomes in the VHA are comparable with those documented in the private sector.

Elective surgery for diverticular disease in U.S. veterans: A VASQIP study of national trends and outcomes from 2004 to 2018.

BACKGROUND: Treatment for diverticular disease has evolved over time. In the United States, there has been a trend towards minimally invasive surgical approaches and fewer postoperative complications, but no study has investigated this subject in the Veterans Health Administration. METHODS: This retrospective review identified patients undergoing elective surgery for diverticular disease from 2004 to 2018. Demographics, comorbidities, operative approach, rates of ostomy creation, and 30-day outcomes were compared. The 15-year time period was divided into 3-year increments to assess changes over time. RESULTS: 4198 patients were identified. Complication rate decreased significantly over time (28.1%-15.7%, p < 0.001), as did infectious complications (21.5-6.3%, p < 0.001). Median hospital length-of-stay decreased from 7 to 5 days (p < 0.001). Rates of laparoscopic surgery increased over time (17.7%-48.1%, p < 0.001). CONCLUSIONS: Increased utilization of laparoscopy in veterans undergoing elective surgery for diverticular disease coincided with fewer complications and a shorter length-of-stay. These trends mirror outcomes reported in non-veterans.

Outcomes of Paraesophageal Hernia Repair: Analysis of the Veterans Affairs Surgical Quality Improvement Program Database.

BACKGROUND: While there have been many outcome studies on paraesophageal hernia repair in the civilian population, there is sparse recent data on the veteran population. This study analyzes the mortality and morbidities of veterans who underwent paraesophageal hernia repair in the Veterans Affairs Surgical Quality Improvement Program database. METHODS: Veterans who underwent paraesophageal hernia repair from 2010 to 2017 were identified using Current Procedural Terminology codes. Multivariable analysis was used to compare laparoscopic and open, including abdominal and thoracic approaches, groups. The outcomes were postoperative complications and mortality. RESULTS: There were 1607 patients in the laparoscopic group and 366 in the open group, with 84.1% men and mean age of 61 years. Gender and body mass index did not influence the type of surgical approach. The mortality rates at 30 and 180 days were 0.5% and 0.7%, respectively. Postoperative complications, including reintubation (2.2%), pneumonia (2.0%), intubation > 48 h (2.0%), and sepsis (2.0%) were higher in the open group (15.9% versus 7.2%, p < 0.001). The laparoscopic group had a significantly shorter length of stay (4.3 versus 9.6 days, p < 0.001) and a lower percentage of return to surgery within 30 days (3.9% versus 8.2%, p < 0.001) than the open group. The ratio of open versus laparoscopic paraesophageal hernia repairs varied significantly by different Veterans Integrated Services Network regions. CONCLUSIONS: Veterans undergoing laparoscopic paraesophageal hernia repair experience similar outcomes as patients in the private sector. Veterans who underwent laparoscopic paraesophageal hernia repair had significantly less complications compared to an open approach even after adjusting for patient comorbidities and demographics. The difference in open versus laparoscopic practices between various regions requires further investigation.

30-Day outcomes and predictors of complications after Puestow procedure.

BACKGROUND: A lateral pancreaticojejunostomy, or a Puestow procedure, is used in chronic pancreatitis with ductal dilation and pain. The current literature on the Puestow is sparse. This study examines outcomes of Puestow procedures nationwide. METHODS: Using ACS-NSQIP database, patients who underwent a Puestow procedure from 2010 to 2016 were identified. Univariate analysis and multivariable regression models were used to identify predictors of mortality and morbidities. Covariates included in the regression models were chosen based on clinical significance. RESULTS: The cohort included 524 patients. The 30-day mortality rate was 1.2%(n = 6). At least one major complication occurred in 19.1% of patients including death (1.2%), major organ dysfunction (8.2%), pulmonary embolism (1.3%), and surgical site infections (13.0%). Diabetes, COPD, and transfusions were the strongest predictors of complications. CONCLUSIONS: The Puestow procedure is an acceptable treatment modality with low rates of morbidity and mortality. Minimizing transfusions and optimizing pulmonary status may improve 30-day outcomes.

Impact of Operative Times and Mesh Utilization on Paraesophageal Hernia Repair: Analysis of 30-Day Outcomes from the American College of Surgeons National Surgical Quality Improvement Project Database.

BACKGROUND: Using mesh to buttress the crural repair following a paraesophageal hernia repair remains controversial. This article evaluates recent trends in laparoscopic paraesophageal hernia repairs and analyzes the impact of mesh and operative time on postoperative morbidity. METHODS: The 2013-2015 American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP) database was queried for elective laparoscopic paraesophageal hernia repair with and without mesh. Operative times were grouped into quartiles and statistical analysis was performed using analysis of variance univariate with post hoc testing and multivariate regression modeling. The outcomes of interest were composite morbidity scores and readmission rates within 30 days of surgery. RESULTS: The database identified a cohort of 6234 laparoscopic paraesophageal hernia repairs. Mesh was utilized in 42% of cases per year and did not change over the study period (P = .367). Mesh was used 37%, 40%, 43%, and 49% of the time within operative quartiles 1, 2, 3, and 4, respectively (P < .001). Postoperative morbidity and readmission rates for each operative time quartile were 2.8%, 4.1%, 5.42%, and 6.13% (P < .001) and 4.4%, 5%, 6.2%, and 7.6% (P = .001), respectively. Post hoc testing indicated statistically significant differences in postoperative morbidity and readmission rates between quartiles 1 and 3/4. Multivariate regression analysis documented operative time as a risk factor for postoperative morbidities and readmission. Simply using mesh was not directly associated with postoperative morbidity. CONCLUSION: Mesh utilization does not impact postoperative outcomes; however, as operative time increases, the incidence of postoperative morbidity also increases.

Robotic Right Colectomy for Colon Cancer: Comparison of Outcomes from a Single Institution with the ACS-NSQIP Database.

BACKGROUND: Robotic surgery has increased in recent years for the treatment of colorectal cancer; however, it is not yet the standard of care. This study aims to compare the 30-day outcomes after robotic colectomy for right-sided colon cancer from our institution with those from a national dataset, the targeted colectomy American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. METHODS: Patients undergoing elective, robotic, right colon resection for stage I, II, and III colon cancer were identified within the targeted colectomy ACS-NSQIP database from 2012 to 2014. Patients meeting the same criteria were identified within a prospectively maintained institutional database from 2009 to 2015. Univariate analyses using chi-square tests and Student's t-tests were done where appropriate to compare baseline characteristics and outcomes between the two groups. RESULTS: Patients at our institution had a significantly higher average number of lymph nodes retrieved (24.4 versus 20.1, P = .046). There was no statistically significant difference between the two groups regarding the incidence of wound infections, anastomotic leaks, blood transfusions, unplanned return to the operating room, or prolonged length of hospital stay. There were no 30-day mortalities at our institution and only one in the ACS-NSQIP database. CONCLUSIONS: Our institutional experience with robotic right colon resection is equivalent to that of a national sample. This study demonstrates the safety of performing robotic right hemicolectomy for the treatment of colon cancer.

Laparoscopic Hiatal Hernia Repair with Falciform Ligament Buttress.

BACKGROUND: Using synthetic mesh to buttress the crural repair during laparoscopic hiatal hernia repair may be associated with dysphagia and esophageal erosions, while a biologic mesh is expensive and does not decrease long-term recurrence rates. This study documents outcomes of laparoscopic paraesophageal hernia repairs using the falciform ligament to reinforce the crural repair. METHODS: This is a prospective study of laparoscopic paraesophageal hernia repairs with a falciform ligament buttress. Preoperatively and at 6 and 12 months postoperatively, medications, radiologic studies, and symptom severity and frequency scores were recorded. Patients with a hiatal defect greater than 5 cm were included, while patients with recurrent hiatal hernia repairs or prior gastric surgery were excluded. Symptom scores were compared pre- and postoperatively with a p < 0.05 considered significant. RESULTS: One hundred four patients were included with a mean age of 62.4 years, and 57 patients underwent an upper gastrointestinal series at least 12 months from the initial operation with a mean follow-up of 20.6 months. The mean symptom severity score decreased from 14.32 ± 0.93 to 4.75 ± 0.97 (p < 0.001), mean symptom frequency score decreased from 14.99 ± 0.97 to 5.25 ± 0.99 (p < 0.001), and mean total symptom score decreased from 29.31 ± 1.88 to 10.00 ± 1.95 (p < 0.001). Five patients developed recurrent hiatal hernias on upper gastrointestinal series, but only three required operative intervention. CONCLUSIONS: Laparoscopic paraesophageal hernia repair with a falciform ligament buttress is a viable option for a durable closure. Ongoing follow-up will continue to illuminate the value of this approach to decrease morbidity and recurrence rates for hiatal hernia repair.

A predictive model for patients with median arcuate ligament syndrome.

BACKGROUND: Due to the rarity of median arcuate ligament (MAL) syndrome, patient selection for surgery remains difficult. This study provides a predictive model to optimize patient selection and predict outcomes following a MAL release. METHODS: Prospective data from patients undergoing a MAL release included demographics, radiologic studies, and SF-36 questionnaires. Successful postoperative changes in SF-36 was defined as an improvement > 10% in the total SF-36 score. A logistic regression model was used to develop a clinically applicable table to predict surgical outcomes. Celiac artery (CA) blood flow velocities were compared pre- and postoperatively and Pearson correlations were examined between velocities and SF-36 score changes. RESULTS: 42 patients underwent a laparoscopic MAL release with a mean follow-up of 28.5 ± 18.8 months. Postoperatively, all eight SF-36 scales improved significantly. The logistic regression model for predicting surgical benefit was significant (p = 0.0244) with a strong association between predictors and outcome (R2 = 0.36). Age and baseline CA expiratory velocity were significant predictors of improvement and predicted clinical improvement. There were significant differences between pre- and postoperative CA velocities. Postoperatively, the bodily pain scale showed the most significant increase (64%, p < 0.0001). A table was developed using age and preoperative CA expiratory velocities to predict clinical outcomes. CONCLUSIONS: Laparoscopic MAL produces significant symptom improvement, particularly in bodily pain. This is one of the first studies that uses preoperative data to predict symptom improvement following a MAL release. Age and baseline CA expiratory velocity can be used to guide postoperative expectations in patients with MAL syndrome.

Right Colon Resection for Colon Cancer: Does Surgical Approach Matter?

BACKGROUND: Surgical resection with curative intent remains the standard of care for colon cancer. This study aims to compare the 30-day outcomes and oncologic results following open, laparoscopic, and robot-assisted right colon resection for colon cancer using the Targeted Colectomy American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. MATERIALS AND METHODS: All patients undergoing elective, right colon resection with primary anastomosis were identified within the targeted colectomy ACS-NSQIP database. Only patients with stage I, II, or III colon cancer were included. The association of surgical approach with oncologic results and 30-day morbidity and mortality outcomes was investigated using a variety of statistical tests. RESULTS: A total of 3518 patients met inclusion criteria; 1024 (29.1%) underwent open surgery (OS), 2405 (63.4%) underwent laparoscopic surgery, and 89 (2.5%) underwent robotic surgery. Patients undergoing OS were significantly more likely to have positive resection margins (P < .001). Patients undergoing OS were significantly more likely to experience prolonged intubation (P = .02), deep wound infections (P = .001), wound dehiscence (P = .005), deep venous thrombosis (P = .04), bleeding requiring a blood transfusion (P < .001), a prolonged postoperative ileus (P < .001), and longer length of hospital stay (P < .001), and were more likely to die (P = .02). CONCLUSION: The laparoscopic approach to colon resection for colon cancer has lower 30-day morbidity compared to OS. The robotic approach is equivalent to the laparoscopic approach, and its utilization may increase in the future.

Median arcuate ligament syndrome in athletes.

BACKGROUND: Exercise-related transient abdominal pain (ETAP) is a common entity in young athletes. Most occurrences are due to a "cramp" or "stitch," but an uncommon, and often overlooked, etiology of ETAP is median arcuate ligament syndrome (MALS). The initial presentation of MALS typically includes postprandial nausea, bloating, abdominal pain, and diarrhea, but in athletes, the initial presentation may be ETAP. METHODS: We present a case series of three athletes who presented with exercise-related transient abdominal pain and were ultimately diagnosed and treated for MALS. Unlike other patients with median arcuate ligament syndrome, these athletes presented with exercise-induced pain, rather than the common postprandial symptoms. These symptoms persisted despite conservative measures. Work-up of patients with suspected MALS include a computed tomography or magnetic resonance angiography showing compression of the celiac artery with post-stenotic dilation, or a celiac artery ultrasound demonstrating increased velocities (>200 cm/s2) with deep exhalation. RESULTS: All patients underwent a laparoscopic median arcuate ligament release. Postoperatively, there were no complications, and all were discharged home on postoperative day #2. All patients have subsequently returned to athletics with resolution of their symptoms. CONCLUSION: ETAP is common in athletes and often resolves with preventative or conservative strategies. When ETAP persists despite these methods, alternative causes, including MALS, should be considered. A combination of a thorough history and physical exam, as well as radiographic data, is essential to make the appropriate diagnosis and treatment strategy.

Laparoscopic Puestow: lateral pancreaticojejunostomy.

INTRODUCTION: Chronic pancreatitis is a painful inflammatory disease that leads to progressive and irreversible destruction of pancreatic parenchyma [1]. A lateral pancreaticojejunostomy, also known as the Puestow procedure, is performed for symptomatic chronic pancreatitis associated with a dilated pancreatic duct secondary to calcifications or strictures [4]. An open approach is used traditionally due to the complexity of the case, and there have only been a handful of laparoscopic case reports [2]. This video depicts a laparoscopic lateral pancreaticojejunostomy for chronic pancreatitis. METHODS: A 45-year-old gentleman with a 20-year history of chronic alcohol abuse presented with diffuse abdominal pain. His pain was worse postprandially and associated with loose stools. A computed tomography scan revealed multiple calcified deposits within the body and tail of the pancreas, and a dilated pancreatic duct measuring 1.4 cm with a proximal obstructing calcified stone. A 5-port foregut technique was used, and a 15-cm pancreatic ductotomy was performed with an ultrasonic scalpel. Calcified stones were cleared from the duct, and a roux-en-y pancreaticojejunostomy was performed using a hand-sewn technique. RESULTS: The patient had a relatively uncomplicated hospital course with return of bowel function on postoperative day 4. His patient-controlled analgesic device was discontinued on post operative day 3. He was ambulating, tolerating a regular diet and discharged home on postoperative day 5. At 12- and 26-month follow-up, he remains off narcotics, but still requires 1-2 tabs of pancreatic enzyme replacement per meal. Most importantly, he has not had any alcohol for over 2 years. CONCLUSION: The two primary goals in treating chronic pancreatitis include long-term pain relief and improvements in quality of life [3]. For patients with chronic pancreatitis and a dilated pancreatic duct, a laparoscopic lateral pancreaticojejunostomy may be an effective approach to decrease pain and improve quality of life.

Laparoscopic bilateral cortical-sparing adrenalectomy for pheochromocytoma.

INTRODUCTION: Since laparoscopic adrenalectomy for pheochromocytoma was reported in 1992, the laparoscopic technique has largely replaced the open approach [4]. Numerous studies have demonstrated that the laparoscopic approach is associated with decreased blood loss, shorter hospitalization, faster recovery, and lower cost [1]. Conversion rates are reported at less than 5.5 %, yet concern still exists that intraoperative hypertensive crisis may be more severe with laparoscopy due to increased intraabdominal pressure [3]. Bilateral pheochromocytomas are common in patients with multiple endocrine neoplasia type 2 (MEN 2) or von Hippel-Lindau (VHL) disease. Total adrenalectomy commits the patient to lifelong steroid hormone replacement and the risk of Addisonian crisis after bilateral adrenalectomy [5]; [8]. The risk of malignant pheochromocytomas in patients with or without MEN 2 or VHL is low. The current literature supports cortical-sparing adrenalectomy in patients with bilateral pheochromocytomas [2, 7, 10]. This video presents a patient with bilateral pheochromocytomas who underwent bilateral laparoscopic cortical-sparing adrenalectomies. METHODS: A 40-year-old female presented to her primary care physician with a history of a hypertensive crisis that required an emergent cesarean section. Her workup revealed elevated urinary metanephrines, and a CT scan showed a left adrenal lesion measuring 3.9 cm and a right adrenal lesion measuring 2.7 cm. After undergoing alpha blockade, she was consented for bilateral partial adrenalectomies. A left partial adrenalectomy was performed first using four ports. The ports were then closed and the patient was repositioned in a left lateral decubitus position for a subsequent right partial adrenalectomy. RESULTS: The patient had an uncomplicated hospital course and was discharged home on postoperative day 4. She returned for follow-up at 2 weeks and 1 month and had returned to her normal activities. Testing for MEN and von Hippel-Lindau was both negative. Her electrolyte and cortisol levels normalized, and she was weaned off her postoperative steroids by week five. At 1-year follow-up, she remains off steroids and no longer requires anti-hypertensive medications. CONCLUSION: Laparoscopic adrenalectomy is the gold standard for removal of benign lesions of the adrenal gland. Bilateral pheochromocytomas are more common in the presence of hereditary conditions such as MEN and von Hippel-Lindau and should be ruled out [8, 10]. The risk of Addisonian crisis and lifelong steroid replacement should prompt cortical preservation with bilateral disease [9]. Laparoscopic bilateral partial adrenalectomies should be considered in patients with bilateral pheochromocytomas [6]. Finally, all patients undergoing pheochromocytoma excision require lifelong follow-up to monitor for recurrence.

Incisional and port-site hernias following robotic colorectal surgery.

BACKGROUND: The association between extraction site location, robotic trocar size, and the incidence of incisional hernias in robotic colorectal surgery remain unclear. Laparoscopic literature reports variable rates of incisional hernias versus open surgery, and variable rates of trocar site hernias. However, conclusions from these studies are confusing due to heterogeneity in closure techniques and may not be generalized to robotic cases. This study evaluates the effect of extraction site location on incisional hernia rates, as well as trocar hernia rates in robotic colorectal surgery. MATERIALS AND METHODS: A retrospective review of multiport and single incision robotic colorectal surgeries from a single institution was performed. Patients underwent subtotal, segmental, or proctocolectomies, and were compared based on the extraction site through either a muscle-splitting (MS) or midline (ML) incision. Hernias were identified by imaging and/or physical exam. Demographics and risk factors for hernias were assessed. Groups were compared using a multivariate logistic regression analysis. RESULTS: The study included 259 colorectal surgery patients comprising 146 with MS and 113 with ML extraction sites. Postoperative computed tomograms were performed on 155 patients (59.8 %) with a mean follow-up of 16.5 months. The overall incisional hernia rate was 5.8 %. A significantly higher hernia rate was found among the ML group compared to the MS group (12.4 vs. 0.68 %, p < 0.0001). Of the known risk factors assessed, only increased BMI was associated with incisional hernias (OR 1.18). No trocar site hernias were found. CONCLUSION: Midline extraction sites are associated with a significantly increased rate of incisional hernias compared to muscle-splitting extraction sites. There is little evidence to recommend fascia closure of 8-mm trocar sites.

Exercise-related transient abdominal pain secondary to median arcuate ligament syndrome: a case report.

Exercise-related transient abdominal pain is a common entity in young athletes. An uncommon aetiology of this type of pain is median arcuate ligament syndrome. This article details an 18-year-old field hockey player who presented with a 1-year history of exercise-related transient abdominal pain. Despite a trial of preventative strategies, the patient's pain persisted, prompting surgical intervention. Following a laparoscopic median arcuate ligament release, the patient's symptoms resolved. Therefore, when exercise-related transient abdominal pain persists despite precautionary measures, median arcuate ligament syndrome should be considered.
