Omental vascularized lymph node transplant for the treatment of breast lymphedema: A case report.

Breast lymphedema is a type of breast cancer related lymphedema that leads to significant discomfort and negative impact on body image. Conservative therapy and lymphovenous bypass have been previously described as possible treatment methods for breast lymphedema, however, a unified approach to treatment is lacking. The current report describes a case of breast lymphedema successfully treated with vascularized lymph node transfer (VLNT) after failed attempt at management with conservative therapy. The patient is a 48-year-old female with right-sided breast cancer who underwent breast conservation therapy in 2015 and subsequently developed pain and swelling of the right breast. The diagnosis of breast lymphedema was supported by clinical evaluation as well as MRI, lymphoscintigraphy, and lymphography. In consultation with a breast surgeon, breast lymphedema was determined not to be an indication for mastectomy. The patient was offered and underwent an omental VLNT to the right breast. A 20 cm segment of omentum with associated gastroepiploic vessels and lymph nodes was harvested, transferred to the right axilla and gastroepiploic vessels were anastomosed to the recipient thoracodorsal vessels. The patient tolerated the procedure well and there were no complications. Additional donor sites were considered, such as the groin and submental regions, but an omental flap was favored in this case because of the lower risk of donor site lymphedema. In the years following, the patient reported significant improvement in symptoms as well as objective reduction of edema on MRI. We propose the consideration of VLNT for breast lymphedema refractory to other methods of management.

Flowthrough Omental Flap for Vascularized Lymph Node Transplant of the Lower Extremity.

SUMMARY: Vascularized lymph node transplantation is a surgical approach for the treatment of chronic lymphedema. However, there is no clinical standard for flap placement nor vascular anastomoses. The authors propose a novel flowthrough configuration for an omental vascularized lymph node transplant in the popliteal space. To prepare the popliteal space for an omental free flap, the medial popliteal fat pad and medial head of the gastrocnemius muscle were debulked. Venous anastomoses were completed with vein couplers, joining the right gastroepiploic vein to the medial sural venae comitantes and the left gastroepiploic vein to the lesser saphenous vein. Arterial anastomoses were hand sewn, joining the right gastroepiploic artery to the proximal medial sural artery and the left gastroepiploic artery to the distal medial sural artery, to create the flowthrough configuration. A retrospective review of patients who underwent this procedure at a single institution was performed. Six patients with chronic lymphedema of the lower extremity underwent vascularized lymph node transplantation from June of 2019 to November of 2020. Five patients underwent at least 3 months of postoperative surveillance, with no postoperative complications reported. In this technique contribution, the authors describe a novel flowthrough configuration for an omental free flap to the popliteal space. The popliteal space offers an aesthetically favorable recipient location when appropriately prepared. The medial sural vessels are ideal recipient vessels for the flowthrough omental flap. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

The Boston lymphatic center's early experience with lymph node transplantation to the upper extremity.

Aim: Although vascularized lymph node transplantation (VLNT) has gained recognition as an effective treatment option for lymphedema, no consensus on the timing of transplant with other lymphatic procedures has been established. The aim of this study is to describe our institutional experience with VLNT, including our staged approach and report postoperative outcomes. Methods: A retrospective review of patients who underwent VLNT for upper extremity lymphedema from May 2017 to April 2022 was conducted. Patients were divided into fat- or fluid-dominant phenotypes based on preoperative workup. Patients with a minimum of 12-month follow-up were included. Records were reviewed for demographic, intraoperative, and surveillance data. Results: Twenty-three patients underwent VLNT of the upper extremity during the study period, of which eighteen met the study criteria. Nine patients had fluid-dominant disease and nine patients had fat-dominant disease and had undergone prior debulking at our institution. Fluid-dominant patients demonstrated slight reductions in limb volume and hours in compression, and improvement in quality-of-life scores at twelve months. Fat-dominant patients who underwent prior debulking had a slight increase in limb volume without a change in hours of compression, and demonstrated improvements in quality-of-life scores in nearly all subdomains. Overall, 17% of patients discontinued compression therapy entirely. Improvement in extremity edema was present in 83% of postoperative MRIs. Conclusion: VLNT had varying effects on limb measurements while reliably improving quality-of-life and allowing for the potential of discontinuing compression. Utilizing a staged approach wherein debulking is performed upfront may be particularly beneficial for patients with fat-dominant disease.

Treatment burden of robotic gastrectomy for locally advanced gastric cancer (LAGC): a single western experience.

BACKGROUND: This study compares standard of care (SOC) open and robotic D2-gastrectomy for locally advanced gastric cancer (LAGC) in the Western context of low disease prevalence, reduced surgical volume, and neoadjuvant chemotherapy (NAC). We hypothesized that robotic gastrectomy (RG) after NAC reduces treatment burden for LAGC across multiple outcome domains vs. SOC. METHODS: Single institution, interrupted time series comparing SOC (2008-2013) for LAGC (T2-4Nany/TanyN+) vs. NAC + RG (2013-2018). Treatment burden was a composite metric of narcotic consumption, oncologic efficacy, cumulative morbidity, and 90-day resource utilization. Predictors were evaluated via multivariate modeling. Learning curve analysis was done using CUSUM. RESULTS: After exclusions, 87 subjects with equivalent baseline characteristics, aside from male sex, were treated via SOC (n=55) or NAC + RG (n=32). All four domains of treatment burden were significantly reduced in the NAC + RG cohort compared to SOC (P=0.003). The odds ratio for excess treatment burden in the NAC/RG was 0.23 (95% CI: 0.07-0.72, P=0.0117) vs. SOC upon multivariable modeling, whereas the extent of resection (total/subtotal), tumor size, T-stage, sex, and early learning curve had no effect. Differences in treatment burden persisted in subgroup analysis for NAC (n=51). CONCLUSIONS: NAC + RG was associated with decreased treatment burden relative to SOC for LAGC. Frequencies of unfavorable hospitalization, adverse oncological outcomes, major morbidity, and narcotic consumption all decreased in this interrupted time series.

Flow-through Omental Flap for Vascularized Lymph Node Transfer: A Novel Surgical Approach for Delayed Lymphatic Reconstruction.

The vascularized omental free flap has been described as a reliable option for the treatment of peripheral lymphedema. However, the flap has been associated with venous hypertension which may require venous supercharging or intra-flap arteriovenous fistula creation to offload the arterial inflow. The aim of this study is to introduce and present our experience using a flow-through omental flap as a novel approach to optimize flap hemodynamics. A retrospective review of a prospectively maintained quality improvement database was performed. Seven consecutive patients with unilateral breast cancer-related lymphedema (BCRL) who underwent delayed lymphatic reconstruction using a flow-through omental free flap were identified. In all patients, the right gastroepiploic artery and vein were anastomosed to the proximal end of the radial artery and to one venae comitante, respectively. An anastomosis of the distal end of the radial artery to the left gastroepiploic artery was performed. The flap was then supercharged by anastomosing the left gastroepiploic vein to the cephalic or basilic vein. There were no flap losses or other surgical complications. A distinct advantage of this inset includes the ability to moderate the arterial in-flow to the omental flap to avoid an inflow-outflow mismatch and alleviate venous hypertension. Further study is needed to validate this technique in a larger study sample with longer follow-up.

Using Individual Clinical Evaluations to Assess Residents' Clinical Judgment; Feasibility and Residents' Perception.

OBJECTIVE: In surgical training, most assessment tools focus on advanced clinical decision-making or operative skill. Available tools often require significant investment of resources and time. A high stakes oral examination is also required to become board-certified in surgery. We developed Individual Clinical Evaluation (ICE) to evaluate intern-level clinical decision-making in a time- and cost-efficient manner, and to introduce the face-to-face evaluation setting. DESIGN: Intern-level ICE consists of 3 clinical scenarios commonly encountered by surgical trainees. Each scenario was developed to be presented in a step-by-step manner to an intern by an attending physician or chief resident. The interns had 17 minutes to complete the face-to-face evaluation and 3 minutes to receive feedback on their performance. The feedback was transcribed and sent to the interns along with incorrect answers. Eighty percent correct was set as a minimum to pass each scenario and continue with the next one. Interns who failed were retested until they passed. Frequency of incorrect response was tracked by question/content area. After passing the 3 scenarios, interns completed a survey about their experience with ICE. SETTING: Beth Israel Deaconess Medical Center, an academic tertiary care facility located in Boston, Massachusetts. PARTICIPANTS: All first-year surgery residents in our institution (n = 17) were invited to complete a survey. RESULTS: All 2016-2017 surgical interns (17) completed the ICEs. A total of $171 (US) was spent conducting the ICEs, and an average of 17 minutes was used to complete each evaluation. In total, 5 different residents failed 1 scenario, with the most common mistake being: failing to stabilize respiration before starting management. After completing the 3 clinical scenarios, more than 90% of respondents agreed or strongly agreed that the evaluations were appropriately challenging for training level, and that the evaluations helped to identify personal strengths and weaknesses in skill and knowledge. The majority believed their knowledge improved as a result of the ICE and felt better prepared to manage these scenarios (88% and 76%, respectively). CONCLUSIONS: The ICE is an inexpensive and time efficient way to introduce interns to board type examinations and assess their preparedness for perioperative patient care issues. Common errors were identified which were able to inform educational efforts. ICEs were well accepted by residents. Next steps include extension of the ICE to PGY2 and PGY3 residents.

Quantifying Lymph Nodes During Lymph Node Transplantation: The Role of Intraoperative Ultrasound.

Quantifying lymph nodes in vascularized lymph node transfer (VLNT) has been performed using preoperative percutaneous ultrasound. The higher resolution and accuracy of intraoperative ultrasound (IOUS) over transcutaneous ultrasound has been demonstrated in the radiology literature for the identification and characterization of finer structures including hepatic lesions, pancreatic lesions, and biliary or pancreatic ducts. We hypothesize that IOUS during VLNT would be a superior method to quantify and map lymph nodes in our flaps. A prospectively collected database of patients undergoing VLNT over 3 years (October 2014 to October 2017) was reviewed. Patients who underwent IOUS during flap harvest, before pedicle ligation to simultaneously map and quantify the number of lymph nodes were included in the study. Twenty-one patients with an average age of 58.7 years and a mean BMI of 32.3 underwent VLNT with IOUS for chronic lymphedema during the study period. Extremity lymphedema was classified as Campisi IB (n = 7), IIA (n = 7), IIB (n = 5), and IIIA (n = 2). There were 14 superficial circumflex iliac artery flaps, including 4 performed concomitantly with a deep inferior epigastric perforator flap, 1 transverse cervical artery flap, and 6 omental flaps. The average number of lymph nodes transferred per IOUS was 4.3 for superficial circumflex iliac artery flaps, 4 for the transverse cervical artery flap, and 5.2 for the omental flaps. Intraoperative ultrasound allows the lymphatic surgeon to precisely map the location of lymph nodes which can guide intraoperative decision making. As there is no data correlating the number of lymph nodes transferred and outcomes after VLNT, developing a precise intraoperative quantification method is important.

Surgical Practical Skills Learning Curriculum: Implementation and Interns' Confidence Perceptions.

OBJECTIVE: To provide an overview of the practical skills learning curriculum and assess its effects over time on the surgical interns' perceptions of their technical skills, patient management, administrative tasks, and knowledge. DESIGN: An 84-hour practical skills curriculum composed of didactic, simulation, and practical sessions was implemented during the 2015 to 2016 academic year for general surgery interns. Totally, 40% of the sessions were held during orientation, whereas the remainder sessions were held throughout the academic year. Interns' perceptions of their technical skills, administrative tasks, patient management, and knowledge were assessed by the practical skills curriculum residents' perception survey at various time points during their intern year (baseline, midpoint, and final). Interns were also asked to fill out an evaluation survey at the completion of each session to obtain feedback on the curriculum. SETTING: General Surgery Residency program at a tertiary care academic institution. PARTICIPANTS: 20 General Surgery categorical and preliminary interns. RESULTS: Significant differences were found over time in interns' perceptions on their technical skills, patient management, administrative tasks, and knowledge (p < 0.001 for all). The results were also statistically significant when accounting for a prior boot camp course in medical school, intern status (categorical or preliminary), and gender (p < 0.05 for all). Differences in interns' perceptions occurred both from baseline to midpoint, and from midpoint to final time point evaluations (p < 0.001 for all). Prior surgical boot camp in medical school status, intern status (categorical vs. preliminary), and gender did not differ in the interns' baseline perceptions of their technical skills, patient management, administrative tasks, and knowledge (p > 0.05 for all). CONCLUSIONS: Implementation of a Practical Skills Curriculum in surgical internships can improve interns' confidence perception on their technical skills, patient management skills, administrative tasks, and knowledge.

Upper extremity deep venous thrombosis after port insertion: What are the risk factors?

BACKGROUND: Totally implantable venous access devices (ports) are widely used, especially for cancer chemotherapy. Although their use has been associated with upper extremity deep venous thrombosis, the risk factors of upper extremity deep venous thrombosis in patients with a port are not studied adequately. METHODS: The Healthcare Cost and Utilization Project's Florida State Ambulatory Surgery and Services Database was queried between 2007 and 2011 for patients who underwent outpatient port insertion, identified by Current Procedural Terminology code. Patients were followed in the State Ambulatory Surgery and Services Database, State Inpatient Database, and State Emergency Department Database for upper extremity deep venous thrombosis occurrence. The cohort was divided into a test cohort and a validation cohort based on the year of port placement. A multivariable logistic regression model was developed to identify risk factors for upper extremity deep venous thrombosis in patients with a port. The model then was tested on the validation cohort. RESULTS: Of the 51,049 patients in the derivation cohort, 926 (1.81%) developed an upper extremity deep venous thrombosis. On multivariate analysis, independently significant predictors of upper extremity deep venous thrombosis included age <65 years (odds ratio = 1.22), Elixhauser score of 1 to 2 compared with zero (odds ratio = 1.17), end-stage renal disease (versus no kidney disease; odds ratio = 2.63), history of any deep venous thrombosis (odds ratio = 1.77), all-cause 30-day revisit (odds ratio = 2.36), African American race (versus white; odds ratio = 1.86), and other nonwhite races (odds ratio = 1.35). Additionally, compared with genitourinary malignancies, patients with gastrointestinal (odds ratio = 1.55), metastatic (odds ratio = 1.76), and lung cancers (odds ratio = 1.68) had greater risks of developing an upper extremity deep venous thrombosis. CONCLUSION: This study identified major risk factors of upper extremity deep venous thrombosis. Further studies are needed to evaluate the appropriateness of thromboprophylaxis in patients at greater risk of upper extremity deep venous thrombosis.

Totally Implantable Venous Access Devices: A Review of Complications and Management Strategies.

OBJECTIVE: Totally implantable venous access devices (portacaths, or "ports"), are widely used for intermittent central venous access especially for cancer patients. Although ports have a superior safety margin compared with other long-term venous access devices, there are a number of complications associated with their use. METHODS: This is a narrative review. We searched PubMed and Google Scholar for articles about complications related to the use of portacaths. "Similar articles" feature of PubMed and reference list of the existing literature were also reviewed for additional relevant studies. RESULTS: In this review, we provide the latest evidence regarding the most common ones of these adverse events and how to diagnose and treat them. Immediate complications including pneumothorax, hemothorax, arterial puncture, and air embolism as well as late complications such as port infection, malfunction, and thrombosis are covered in detail. CONCLUSIONS: Physicians should be familiar with port complications and their diagnosis and management.

Percutaneous versus Cut-Down Technique for Indwelling Port Placement.

The superiority of surgical cut-down of the cephalic vein versus percutaneous catheterization of the subclavian vein for the insertion of totally implantable venous access devices (TIVADs) is debated. To compare the safety and efficacy of surgical cut-down versus percutaneous placement of TIVADs. This is a single-institution retrospective cohort study of oncologic patients who had TIVADs implanted by 14 surgeons. Primary outcomes were inability to place TIVAD by the primary approach and postoperative complications within 30 days. Multivariate analysis was performed by logistic regression. Secondary outcomes included operative time. Two hundred and forty-seven (55.9%) percutaneous and 195 (44.1%) cephalic cut-down patients were identified. The 30-day complication rate was 5.2 per cent: 14 patients (5.7%) in the percutaneous and nine (4.6%) in the cut-down group. The technique was not a significant predictor of having a 30-day complication (odds ratio = 0.820; 95% confidence interval 0.342-1.879). Implantation failure was observed in 16 percutaneous patients (6.5%) and 28 cut-down patients (14.4%) (adjusted odds ratio for cephalic vs cut-down = 2.387; 95% confidence interval 1.275-4.606). The median operative time for percutaneous patients was 46 minutes (interquartile range = 35, 59) versus 37.5 minutes (interquartile range = 30, 49) for cut-down patients(P < 0.0001). Both the percutaneous and cut-down technique are safe and effective for TIVAD implantation. Operative times were shorter and the odds of implantation failure higher for cephalic cut-down. As implantation failure is common, surgeons should familiarize themselves with both techniques.

Appendicitis in the modern era: universal problem and variable treatment.

BACKGROUND: Acute appendicitis is the second most common gastrointestinal diagnosis mandating urgent operation in the U.S. The current state of adult appendectomy, including patient and hospital characteristics, complications, and predictors for complications, are unknown. METHODS: Retrospective review of U.S. Nationwide Inpatient Sample 2003-2011 for appendectomy in ≥18-year-olds was performed. Primary outcomes measures included postoperative complications, length of stay, and patient mortality. Categorical variables were analyzed by χ2, trend analyses by Cochran-Armitage. Multivariable logistic regression was performed to adjust for predictors of developing complications. RESULTS: 1,663,238 weighted appendectomy discharges occurred. Over the study period, complications increased from 3.2 to 3.8% (p < 0.0001), but the overall mortality decreased from 0.14 to 0.09% (p < 0.0001) and mean LOS decreased from 3.1 to 2.6 days (p < 0.0001). The proportion of laparoscopic appendectomy increased over time, 41.7-80.1% (p < 0.0001). Patients were increasingly older (≥65 years: 9.4-11.6%, p < 0.0001), more obese (3.8-8.9%, p < 0.0001), and with more comorbidities (Elixhauser score ≥3: 4.7-9.8%, p < 0.0001). After adjustment, independent predictors for postoperative complications included: open surgery (OR 1.5, 95% C.I. 1.4-1.5), male sex (OR 1.6, 95% CI 1.5-1.6), black race (vs. white: OR 1.5, 95% CI 1.4-1.6), perforated appendix (OR 2.8, 95% CI 2.7-3.0), greater comorbidity (Elixhauser ≥3 vs. 0, OR 11.3, 95% CI 10.5-12.1), non-private insurance status (vs. private: Medicaid OR 1.3, 95% CI 1.2-1.4; Medicare OR 1.7, 95% CI 1.6-1.8), increasing age (>52 years vs. ≤27: OR 1.3; 95% CI 1.2-1.4), and hospital volume (vs. high: low OR 1.2; 95% CI 1.1-1.3). Predictors of laparoscopic appendectomy were age, ethnicity, insurance status, comorbidities, and hospital location. CONCLUSIONS: Laparoscopic appendectomy is increasing but is unevenly deployed across patient groups. Appendectomy patients were increasingly older, with more comorbidities and with increasing rates of obesity. Black patients and patients with public insurance had less utilization of laparoscopy and inferior outcomes.

Role of ventriculoperitoneal shunting in patients with neoplasms of the central nervous system: An analysis of 59 cases.

Approximately 1-5% of patients with cerebral metastasis and ~40% of patients with primary brain tumors suffer from hydrocephalus. These patients often exhibit a poor prognosis. The aim of the present study was to reassess the validity of ventriculoperitoneal shunting (VPS) with the assistance of the general surgeon in oncological patients. A total of 59 patients underwent first-time VPS at the Beth Israel Deaconess Medical Center (Boston, USA) between 2004 and 2012; 40 patients had hydrocephalus from brain metastasis and 19 from primary tumors. The analyzed independent variables included demographics, body mass index, past medical history, clinical presentation, indication for surgery, Karnofsky performance status (KPS) score and surgical technique; the dependent variables were postoperative symptoms and occurrence, cause and time of shunt failure. The outcomes were analyzed with the t-test and Kaplan-Meier estimates for shunt survival. The mean age of the patients was 57.2 years and the mean operative time was 50.4 min. Symptomatic palliation was achieved in 93% of the cases; patients with severe symptoms, such as debilitating headaches, nausea and vomiting, benefited significantly from VPS. The mean follow-up time was 6.3 months; complications occurred in only 7 patients (11.8%) during follow-up: 2 in the proximal shunt (1 infection and 1 obstruction), both requiring revision, 1 infection in the distal catheter requiring shunt removal, 2 cases of intracerebral bleeding that were monitored with computed tomography scans, 1 wound infection treated with antibiotics and 1 valve complication that required temporary revision. The initial and 3-month KPS scores were 65±16.4 and 75±16.0, respectively. The mean overall shunt survival was 6.4 months (range, 1.0 day-76.0 months) from the placement of the VP shunt. At 3 months after VPS, 93.5% of the patients remained alive with functioning shunts and at 1 year 87% of the shunts were still functioning. In conclusion, VPS remains a valid option for cancer patients with low KPS, as it improves the quality of life in such patients, even in the setting of previous infection, hemorrhage, or leptomeningeal disease, since shunt patency outlasts the overall survival of nearly all patients.

Feasibility of minimally invasive esophagectomy after neoadjuvant chemoradiation.

BACKGROUND: The impact of preoperative chemoradiation treatment (CRT) on outcomes after esophagectomy is still debated. The choice of surgical approach can also be influenced by this treatment modality, including the performance of minimally invasive esophagectomy (MIE), a technically demanding procedure. We sought to examine the outcomes of MIE after CRT. MATERIALS AND METHODS: We conducted a retrospective analysis of consecutive MIEs performed at two institutions from June 2004 to January 2010. We analyzed the effect of CRT on perioperative results, including pulmonary complications, oncological outcomes, length of stay, and mortality. RESULTS: In total, 126 patients were eligible for the study. Six patients (4.8%) were converted from MIE to an open approach and were excluded from the analysis. Of the 120 patients, 98 were male (82%), mean age was 62 ± 13 years (range, 22-88 years), and 58 underwent CRT (48%) (Group 1). Comparing both groups, the incidence of pneumonia (9 versus 11), recurrent laryngeal nerve injury (3 versus 5), anastomotic leaks (4 versus 9), number of harvested lymph nodes (16 ± 9 versus 18 ± 9), and R0 resection margins (53/58 versus 61/62) was comparable (Group 1 versus Group 2, respectively; P=not significant). There was a trend toward more pleural effusions in Group 1 (10 versus 4, P=.09). Median length of stay was comparable between both groups (10 ± 11 versus 11 ± 7 days). There were three operative deaths, exclusively in Group 1 (P=.11). CONCLUSIONS: MIE can be safely performed after CRT in the management of esophageal cancer, with a low conversion rate. Outcomes seem comparable regardless of preoperative CRT.

Ventriculoperitoneal shunting: Laparoscopically assisted versus conventional open surgical approaches.

OBJECTIVES: Ventriculoperitoneal shunting (VPS) is a mainstay of hydrocephalus therapy, but carries a significant risk of device malfunctioning. This study aims to compare the outcomes of laparoscopic ventriculoperitoneal shunting versus open ventriculoperitoneal shunting (OVPS) VPS-placement and reviews our findings in the pertinent context of the literature from 1993 to 2012. MATERIALS AND METHODS: Between 2003 and 2012, a total of 232 patients underwent first time VPS placement at Beth Israel Deaconess Medical Center. Of those, 155 were laparoscopically guided and 77 were done conventionally. We analyzed independent variables (age, gender, medical history, clinical presentation, indication for surgery and surgical technique) and dependent variables (operative time, post-operative complications, length of stay in the hospital) and occurrence of shunt failure. RESULTS: Mean operative time was 43.7 min (18.0-102.0) in the laparoscopic group versus 63.0 min (30.0-151.0) in the open group, (P < 0.05). Length of stay was similar, 5 days in the laparoscopic and in the open group, (P = 0.945). The incidence of shunt failure during the entire follow-up period was not statistically different between the two groups, occurring in 14.1% in the laparoscopic group and 16.9% in the open group, (P = 0.601). Kaplan-Meier analysis demonstrated no difference in shunt survival between the two groups (P = 0.868), with functionality in 85% at 6-months and 78.5% at 1-year. CONCLUSION: According to our study, LVPS-placement results compare similarly to OVPS placement in most aspects. Since laparoscopic placement is not routinely indicated, we suggest a prospective study to assess its value as an alternate technique especially suitable in obese patients and patients with previous abdominal operations.

Shunting for hydrocephalus: analysis of techniques and failure patterns.

BACKGROUND: Hydrocephalus is characterized by ventricular dilatation because of progressive accumulation of cerebrospinal fluid. Normal pressure hydrocephalus (NPH) affects a subset of patients representing a reversible clinical triad of gait disturbance, urinary incontinence, and dementia with normal cerebrospinal fluid pressure and composition. Various shunting procedures have been used for treatment, but techniques and outcomes remain under debate. The objective of this study was to evaluate the clinical outcomes of 232 patients with and without NPH after the first-time Ventriculoperitoneal shunt placement and assessed patterns of failure between December 2004 and December 2012. RESULTS: Mean age was 54.7 y in non-NPH and 71.9 y in NPH patients. We used open technique in 34.3% and laparoscopic technique in 65.7% of NPH patients and 32.7% and 67.3% of the non-NPH patients, respectively. A total of 36 of 232 patients displayed shunt failure, 16.4% in NPH and 15.2% in non-NPH patients. Twenty-three of 155 patients failed after laparoscopic and 13 of 77 failed after open placement. Proximal shunt failure was more frequent in the non-NPH cohort. Distal failures accounted for 13 of 232 cases, and the difference between laparoscopic (six of 155) and open failures (seven of 77) was profound, but not between NPH- and non-NPH patients. CONCLUSIONS: Shunt failures are related to the placement method. Non-NPH patients showed more proximal failures. NPH patients showed fewer proximal failures. Less distal failures were observed after laparoscopic ventriculoperitoneal shunt placement without significant differences between NPH and non-NPH patients. Beyond this, laparoscopic surgery carries distinct advantages such as shorter operating room times and hospital stays, which should translate into less use of pain medications, earlier mobilization, and a lower incidence of ileus.

Impact of the surgical technique on pulmonary morbidity after esophagectomy.

BACKGROUND: Pulmonary complications occur frequently after esophagectomy. Although multifactorial, these complications could be influenced by surgical technique. We sought to compare the respiratory complications of patients undergoing esophagectomy through different approaches, and identify technical risk factors. METHODS: We conducted a retrospective analysis of consecutive esophagectomies performed at 2 institutions from January 2002 to January 2009. Primary outcome measures included postoperative ventilatory requirements, pneumonia, effusion requiring intervention, length of stay, and mortality. RESULTS: A total of 220 esophagectomies were performed through 6 different approaches: 79 minimally invasive (MIE) with neck anastomosis, 20 MIE with chest anastomosis, 37 transhiatal, 33 McKeown, 36 Ivor Lewis, and 15 left thoracoabdominal. Patients who underwent MIE were more likely to be extubated in the operating room (p<0.01) and had fewer pleural effusions (p<0.01). A thoracotomy was associated with a higher incidence of tracheostomy (p=0.02) and pleural effusions (p=0.02). Neck anastomoses were negatively associated with early extubation (p=0.04) and predicted recurrent laryngeal nerve injury (p=0.04), but were not associated with pneumonia or other pulmonary complications. Multivariate analysis showed that pneumonia was independently associated with advancing age (p=0.02), lack of a pyloric drainage procedure (p=0.03), and less significantly with MIE (p=0.06, fewer events). Surgical approach was not a significant predictor of length of stay or mortality. CONCLUSIONS: Patients undergoing MIE are less likely to remain intubated. Omission of a pyloric drainage procedure or performance of thoracic or neck incisions appear to be important determinants of respiratory complications. Technical aspects of the procedure in addition to the surgical approach influence important respiratory outcomes.

Spontaneous intraperitoneal hemorrhage as the initial presentation of a gastrointestinal stromal tumor: a case report.

BACKGROUND: Spontaneous hemoperitoneum is rare. The most common etiologies are gynecologic, splenic, and hepatic. Gastrointestinal stromal tumors (GISTs) are commonly associated with intraluminal bleeding, but rarely with spontaneous hemoperitoneum. We report a case of spontaneous hemoperitoneum caused by a gastric GIST. CASE REPORT: A 54-year-old male presented with the acute onset of abdominal pain and a drop in hemoglobin. Subsequent evaluation, including a CT, MRI, and EUS, revealed a 1.2-cm mass along the greater curvature of the stomach and associated hemoperitoneum. The patient was taken electively to the operating room for laparoscopic removal of the mass. Pathology confirmed that it was a GIST. CONCLUSION: GIST is a rare clinical entity that infrequently presents with spontaneous hemoperitoneum. Emergent treatment should be guided towards treating the spontaneous hemoperitoneum.

High-frequency probe ultrasonography has limited accuracy for detecting invasive adenocarcinoma in patients with Barrett's esophagus and high-grade dysplasia or intramucosal carcinoma: a case series.

AIM: To evaluate prospectively the accuracy of preoperative high-frequency (20 MHz) probe ultrasonography (HFPUS) for detecting invasive cancer in patients referred for esophagectomy because of an endoscopic biopsy diagnosis of high-grade dysplasia (HGD) or intramucosal carcinoma (ICA) in Barrett's esophagus (BE). PATIENTS AND METHODS: Nine consecutive male patients (median age of 69 yr) who were referred for esophagectomy for HGD or ICA in BE agreed to participate. We performed conventional upper gastrointestinal endoscopy followed by HFPUS using a through-the-scope ultrasound probe (20 MHz), and we compared our preoperative findings with the pathologist's findings in the resected esophageal specimens. RESULTS: There was complete agreement between the postoperative pathological findings and the preoperative HFPUS findings in only 4 of the 9 patients. HFPUS resulted in two false-negative diagnoses of esophageal cancer (both had T1 lesions in the resected specimens), one false-positive diagnosis of esophageal cancer, and two errors in tumor staging (1 understaged, 1 overstaged). CONCLUSIONS: HFPUS has limited accuracy for identifying invasive cancer in patients found to have HGD or IMC in BE. Pending further refinements in technology, clinical management decisions in such patients should not be based solely on the results of HFPUS.
