The contemporary role of minimally invasive esophagectomy in esophageal cancer.

Open surgical resection via transhiatal or transthoracic, including McKeown, access is the most viable option for curing esophageal cancer; however, the extensive nature of open surgery in both the chest and abdomen results in significant rates of morbidity and mortality. A natural response was the introduction of minimally invasive esophagectomy (MIE) and, later, endoscopic resection. In the hands of experienced surgeons, MIE can achieve equivalent or better perioperative mortality, morbidity, and oncologic outcomes as compared to open surgery. This review starts with an overview of open esophagectomy before delving into the evolving body of evidence on MIE outcomes and practices.

Effect of an opioid-free anesthetic on postoperative opioid consumption after laparoscopic bariatric surgery: a prospective, single-blinded, randomized controlled trial.

INTRODUCTION: Opioid administration has the benefit of providing perioperative analgesia but is also associated with adverse effects. Opioid-free anesthesia (OFA) may reduce postoperative opioid consumption and adverse effects after laparoscopic bariatric surgery. In this randomized controlled study, we hypothesized that an opioid-free anesthetic using lidocaine, ketamine, and dexmedetomidine would result in a clinically significant reduction in 24-hour postoperative opioid consumption when compared with an opioid-inclusive technique. METHODS: Subjects presenting for laparoscopic or robotic bariatric surgery were randomized in a 1:1 ratio to receive either standard opioid-inclusive anesthesia (group A: control) or OFA (group B: OFA). The primary outcome was opioid consumption in the first 24 hours postoperatively in oral morphine equivalents (OMEs). Secondary outcomes included postoperative pain scores, patient-reported incidence of opioid-related adverse effects, hospital length of stay, patient satisfaction, and ongoing opioid use at 1 and 3 months after hospital discharge. RESULTS: 181 subjects, 86 from the control group and 95 from the OFA group, completed the study per protocol. Analysis of the primary outcome showed no significant difference in total opioid consumption at 24 hours between the two treatment groups (control: 52 OMEs vs OFA: 55 OMEs, p=0.49). No secondary outcomes showed statistically significant differences between groups. CONCLUSIONS: This study demonstrates that an OFA protocol using dexmedetomidine, ketamine, and lidocaine for laparoscopic or robotic bariatric surgery was not associated with a reduction in 24-hour postoperative opioid consumption when compared with an opioid-inclusive technique using fentanyl.

Gallstone ileus: revisiting surgical outcomes using National Surgical Quality Improvement Program data.

BACKGROUND: Although surgical management remains the mainstay of therapy for gallstone ileus, the optimal approach--enterolithotomy alone or combined with biliary-enteric fistula disruption--is controversial because of the reliance on small single-center series to describe outcomes. Using the American College of Surgeons' National Surgical Quality Improvement Program database, we sought to (1) review the outcomes of patients undergoing surgical management of gallstone ileus and (2) determine if cholecystectomy in addition to enterolithotomy increased morbidity or mortality rate. METHODS: We analyzed the demographics, comorbidities, acuity, operative time, postoperative hospitalization length, and 30-d morbidity and mortality rates of 127 patients from 2005 to 2010 who underwent a procedure for the relief of gallstone ileus. We identified a subset of 14 patients who underwent simultaneous cholecystectomy. We compared the "no cholecystectomy" and "cholecystectomy" groups using standard statistical methods. RESULTS: The overall 30-d postoperative morbidity and mortality rate was 35.4% and 5.5%, respectively. Superficial surgical site infection and urinary tract infection were the most common complications. There was no significant difference in mortality rate between the no cholecystectomy and the cholecystectomy groups (5.3% versus 7.1%, respectively; P = 0.78), but the latter group did experience more minor complications, longer operations, and longer postoperative hospitalization. CONCLUSIONS: Other recent studies on this topic have collected data or reviewed literature across several decades, making this study in particular one of the largest truly modern series. Perhaps reflecting changes in perioperative management, surgical treatment of gallstone ileus is less morbid than previously described, but there is still insufficient evidence to favor concurrent cholecystectomy.

Endoscopic removal of eroded laparoscopic adjustable gastric bands: a preferred approach.

BACKGROUND: Complications related to laparoscopic adjustable gastric banding (LAGB) have led to an increased number of removals. An uncommon but potentially devastating complication is gastric band erosion into the gastric lumen, which can be managed by open surgical, laparoscopic, and endoscopic approaches. OBJECTIVE: A wide array of management techniques has been reported for removal of LAGB that have eroded into the stomach. We describe the preferred method for successful endoscopic band removal at our institution. SETTING: Community tertiary-care referral hospital accredited by the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program. METHODS: A single-center, retrospective review of a prospectively maintained database was used to identify patients who underwent LAGB removal from 2009 to 2019. We identified the subset of patients with band erosion. We analyzed patient characteristics, presenting symptoms, diagnostic modalities, and method of band extraction. RESULTS: A total of 132 patients underwent LAGB removal, among whom 22 (16.7%) patients were diagnosed with erosion. Seven (32%) patients underwent laparoscopic removal, 14 (64%) patients underwent endoscopic removal, and 1 patient (4%) underwent combined laparoscopic and endoscopic approach. These latter patients had variable amounts of erosion and buckle visibility, but all underwent endoscopic retrieval. We found that using an endoscopic retrograde cholangiopancreatography guidewire with an endoscopic retrograde cholangiopancreatography mechanical lithotriptor for band transection and snare for retrieval have been effective. CONCLUSIONS: A standardized, multidisciplinary, and minimally invasive endoscopic approach for LAGB erosion has been found to be successful without the need for further surgical intervention and may be offered to patients upon discovery of erosion.

Impact of Surveillance After Lobectomy for Lung Cancer on Disease Detection and Survival.

INTRODUCTION: Existing guidelines for surveillance after non-small-cell lung cancer (NSCLC) treatment are inconsistent and have relatively sparse supporting literature. This study characterizes detection rates of metachronous and recurrent disease during surveillance with computed tomography scans after definitive treatment of early stage NSCLC. MATERIALS AND METHODS: The incidence of metachronous and recurrent disease in patients who previously underwent complete resection via lobectomy for stage IA NSCLC at a single center from 1996 to 2010 were evaluated. A subgroup analysis was used to compare survival of patients whose initial surveillance scan was 6 ± 3 months (early) versus 12 ± 3 months (late) after lobectomy. RESULTS: Of 294 eligible patients, 49 (17%) developed recurrent disease (14 local only, 35 distant), and 45 (15%) developed new NSCLC. Recurrent disease was found at a mean of 22 ± 19 months, and new primaries were found at a mean of 52 ± 31 months after lobectomy (P < .01). Five-year survival after diagnosis of recurrent disease was significantly lower than after diagnosis of second primaries (2.3% vs. 57.5%; P < .001). In the subgroup analysis of 187 patients, both disease detection on the initial scan (2% [2/94] vs. 4% [4/93]; P = .44) and 5-year survival (early, 80.8% vs. late, 86.7%; P = .61) were not significantly different between the early (n = 94) and the late (n = 93) groups. CONCLUSION: Surveillance after lobectomy for stage IA NSCLC is useful for identifying both new primary as well as recurrent disease, but waiting to start surveillance until 12 ± 3 months after surgery is unlikely to miss clinically important findings.

Necrotizing pancreatitis: challenges and solutions.

Acute pancreatitis is a common disease that can progress to gland necrosis, which imposes significant risk of morbidity and mortality. In general, the treatment for pancreatitis is a supportive therapy. However, there are several reasons to escalate to surgery or another intervention. This review discusses the pathophysiology as well as medical and interventional management of necrotizing pancreatitis. Current evidence suggests that patients are best served by delaying interventions for at least 4 weeks, draining as a first resort, and debriding recalcitrant tissue using minimally invasive techniques to promote or enhance postoperative recovery while reducing wound-related complications.

Benign emptying of the postpneumonectomy space.

A drop in the air-fluid level in the postpneumonectomy space on a chest radiogram is an early sign of bronchopleural fistula (BPF). Any suspicion of BPF points to the need for urgent evaluation and appropriate management. Very rarely may this drop occur without the existence of a fistula, but such a condition is defined as benign emptying of the postpneumonectomy space. We share our successful conservative management in a case of postpneumonectomy space emptying with a suspicion of BPF.

Examining reoperation and readmission after hepatic surgery.

BACKGROUND: Although the perioperative mortality from hepatic resection has improved considerably, this procedure is still associated with substantial morbidity and resource use. The goal of this investigation was to characterize the incidence, patterns, and risk factors for early reoperation and readmission after hepatectomy. STUDY DESIGN: Perioperative outcomes of 1,281 patients undergoing hepatic resection at an academic center from 1996 to 2009 were analyzed. The indications for early reoperation and readmission (90 days) were reviewed. Multivariate logistic regression analysis was performed to determine variables associated with reoperation and readmission. A scoring system was generated to predict the need for readmission after hepatectomy. RESULTS: Eighty-seven patients (6.8%) required reoperation. The perioperative mortality in patients requiring reoperation was significantly higher than for those not requiring reoperation (23.0% vs 3.4%; p < 0.001). Variables associated with reoperation included male sex, performance of concomitant major nonhepatic procedures, and greater intraoperative blood loss. One hundred and eighty-four patients (14.4%) required readmission. Variables associated with readmission included major hepatectomy, development of major postoperative complications, and index hospitalization >7 days. A Readmission Prediction Score ranging from 0 to 4 was generated and directly correlated with need for readmission. CONCLUSIONS: In the current era of hepatic surgery, early reoperation and readmission remain relatively frequent. As we care for patients who are increasingly receiving regionalized care far from home, we must be mindful of patients at increased risk for readmission. The development of strategies to minimize the complications that necessitate reoperation and readmission is critical to improving patient care.
