Complete Common Bile Duct Injury after Laparoscopic Cholecystectomy in Situs Inversus Totalis: A Case Report, Review of the Literature and Illustrative Case Video.

INTRODUCTION AND IMPORTANCE: Situs Inversus Totalis (SIT) is a rare condition characterized by the transposition of internal organs. Given the anatomical variations in SIT, surgeons must exercise extreme caution when performing laparoscopic cholecystectomy to avoid iatrogenic bile duct injury. Despite the high difficulty index associated with laparoscopic cholecystectomy in SIT, there is only one case report of common bile duct (CBD) injury in the English-language literature. CASE PRESENTATION: A 41-year-old female patient, known to have Kartagener syndrome, underwent laparoscopic cholecystectomy for acute cholecystitis and was discharged home on post-operative day one. However, on post-operative day five, the patient presented to the emergency room with abdominal pain, fever, and jaundice. Laboratory tests revealed leukocytosis and hyperbilirubinemia. Radiological images revealed complete occlusion of the CBD. A delayed approach was chosen, and six weeks after her initial operation, a hepaticojejunostomy was performed. CLINICAL DISCUSSION: Laparoscopic cholecystectomy is the standard operative procedure for gallbladder disease. The unique anatomy of SIT increases the risk of CBD injury during laparoscopic cholecystectomy. Surgeons are required to perform a mirror-image procedure and adhere to the basic principles of safe laparoscopic cholecystectomy in SIT. This is only the second reported case of CBD injury in SIT patients. CONCLUSION: Laparoscopic cholecystectomy in SIT presents a significant challenge. In patients with SIT, preventing CBD injury is the best approach, and referral to an experienced hepato-pancreato-biliary (HPB) surgeon is recommended. A delayed approach to CBD injuries in SIT allows thorough planning and understanding of the complex anatomical variations in these patients.

A Case-matched Comparative Study of Laparoscopic Versus Open Right Colonic Resection for Colon Cancer: Developing Country Perspectives.

BACKGROUND: The open approach to right hemicolectomy remains the most widely adopted, whereas laparoscopic surgery is technically more demanding with possible loss of benefit for lengthy procedures compared with open surgery. The aim of this study is to compare the outcomes of the laparoscopic versus open surgery for right colon cancer resections. MATERIALS AND METHODS: Patients who underwent an elective and potentially curative right colectomy for colon cancer between 2015 and 2019 were included and those who underwent emergency surgery, palliative resection, or cytoreductive surgery were excluded. Patients were randomly matched on 1:2 basis for age, disease stage, neoadjuvant chemotherapy, and extent of colectomy (right vs. extended right hemicolectomy, and additional major resection). The analysis was conducted on an intention-to-treat basis. The outcomes were reported as median (range) or percent as appropriate. RESULTS: Among 160 patients, 18 were excluded. The final matching included 69 patients. The were no significant differences between the groups regarding patients' age and sex distribution, tumor size, and preoperative serum albumin and hemoglobin. There were 2 conversions (8.7%) to open surgery. Although the operating time for laparoscopic surgery was longer (200 vs. 140 min, P<0.001), it was associated with less blood loss (50 vs. 100 mL, P=0.001) and shorter primary and total hospital stay (4.1 vs. 6.0 days, P<0.001). There were no differences in the rates of severe complications (0% vs. 13%), reoperations (0% vs. 4.3%), readmissions (13% vs. 8.7%), mortality (0% vs. 2.2%), R0 resections (95.7% vs. 97.8%), and lymph node retrieval rate (28 in each group). CONCLUSION: The laparoscopic approach to right colon resection for colon cancer is associated with less operative trauma and quicker recovery compared with open surgery and offers an equivalent oncologic resection.

A national survey of educational resources utilized by the Resident and Associate Society of the American College of Surgeons membership.

BACKGROUND: Contemporary surgical education includes online resources, mobile platform applications, and simulation training. The aim of this study was to characterize educational tools used by surgical residents. METHODS: An anonymous web-based survey was distributed to 9,913 members of the Resident and Associate Society of the American College of Surgeons. RESULTS: We received 773 completed surveys. To prepare for examinations and expand fund of knowledge, most respondents used printed textbooks, online textbooks, and Surgical Council on Resident Education modules, respectively. Respondents used online textbooks and journal articles most often to investigate timely patient care issues. In contrast, mobile platform applications and online videos/lectures were used least. Fewer than half of respondents used simulators, limited by clinical duties, absence of feedback/supervision, and lack of working supplies. CONCLUSIONS: Traditional educational resources dominate trainee preferences, although utilization of the Surgical Council on Resident Education curriculum continues to grow. Simulators remain a required tool for laparoscopic training, and incorporation of structured feedback and improved supervision may improve utilization.

Pulmonary metastasectomy in colorectal cancer patients with previously resected liver metastasis: pooled analysis.

BACKGROUND: Data addressing the outcomes and patterns of recurrence after pulmonary metastasectomy (PM) in patients with colorectal cancer (CRC) and previously resected liver metastasis are limited. METHODS: We searched the PubMed database for studies assessing PM in CRC and gathered individual data for patients who had PM and a previous curative liver resection. The influence of potential factors on overall survival (OS) was analyzed through univariate and multivariate analysis. RESULTS: Between 1983 and 2009, 146 patients from five studies underwent PM and had previous liver resection. The median interval from resection of liver metastasis until detection of lung metastasis and the median follow-up from PM were 23 and 48 months, respectively. Five-year OS and recurrence-free survival rates calculated from the date of PM were 54.4 and 29.3 %, respectively. Factors predicting inferior OS in univariate analysis included thoracic lymph node (LN) involvement and size of largest lung nodule ≥2 cm. Adjuvant chemotherapy and whether lung metastasis was detected synchronous or metachronous to liver metastasis had no influence on survival. In multivariate analysis, thoracic LN involvement emerged as the only independent factor (hazard ratio 4.86, 95 % confidence interval 1.56-15.14, p = 0.006). CONCLUSIONS: PM offers a chance for long-term survival in selected patients with CRC and previously resected liver metastasis. Thoracic LN involvement predicted poor prognosis; therefore, significant efforts should be undertaken for adequate staging of the mediastinum before PM. In addition, adequate intraoperative LN sampling allows proper prognostic stratification and enrollment in novel adjuvant therapy trials.

Minimally invasive surgery in gastrointestinal cancer: benefits, challenges, and solutions for underutilization.

BACKGROUND AND OBJECTIVES: After the widespread application of minimally invasive surgery for benign diseases and given its proven safety and efficacy, minimally invasive surgery for gastrointestinal cancer has gained substantial attention in the past several years. Despite the large number of publications on the topic and level I evidence to support its use in colon cancer, minimally invasive surgery for most gastrointestinal malignancies is still underused. METHODS: We explore some of the challenges that face the fusion of minimally invasive surgery technology in the management of gastrointestinal malignancies and propose solutions that may help increase the utilization in the future. These solutions are based on extensive literature review, observation of current trends and practices in this field, and discussion made with experts in the field. RESULTS: We propose 4 different solutions to increase the use of minimally invasive surgery in the treatment of gastrointestinal malignancies: collaboration between surgical oncologists/hepatopancreatobiliary surgeons and minimally invasive surgeons at the same institution; a single surgeon performing 2 fellowships in surgical oncology/hepatopancreatobiliary surgery and minimally invasive surgery; establishing centers of excellence in minimally invasive gastrointestinal cancer management; and finally, using robotic technology to help with complex laparoscopic skills. CONCLUSIONS: Multiple studies have confirmed the utility of minimally invasive surgery techniques in dealing with patients with gastrointestinal malignancies. However, training continues to be the most important challenge that faces the use of minimally invasive surgery in the management of gastrointestinal malignancy; implementation of our proposed solutions may help increase the rate of adoption in the future.

Do patients' outcomes suffer when surgical fellows are involved in hepatic resection?

INTRODUCTION: Hepatectomy is an advanced technique learned during surgical fellowship. Outcomes have not been described for hepatectomies involving fellows. METHODS: We analyzed hepatectomies from the 2005-2011 National Surgical Quality Improvement Program database. We compared cases with a fellow (FELLOW group) and those without a fellow (ATTENDING group). RESULTS: FELLOW cases (n = 1,562; 54%) included more major hepatectomies and more metastasectomies (P < .002). Mortality was 3.2% versus 2.7% (P = .5) and morbidity was 30.7% vs 26.2% (P = .008) for FELLOW versus ATTENDING cases. On multivariate analysis, mortality was similar, but morbidity was greater in FELLOW cases (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.02-1.4; P = .03), with increased superficial surgical site infections (OR, 1.72; 95% CI, 1.2-2.4; P = .001). There were no differences in rates of sepsis, cardiac, pulmonary, or thromboembolic complications. Compared with ATTENDING cases, FELLOW cases during the first half of training, carried greater morbidity (OR, 1.43; 95% CI, 1.1-1.8; P = .006); however, this difference disappears by the second half of the academic year. CONCLUSION: Hepatectomy involving a fellow may be associated with an increased risk of surgical site infections. FELLOW cases were more complex. Mortality, cardiac, pulmonary, and other serious morbidities were similar. Despite slightly greater rates of surgical site infections, training in hepatic surgery maintains excellent patient outcomes.

Internal hernia due to adjustable gastric band tubing: review of the literature and illustrative case video.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is a commonly performed bariatric procedure. Device-related morbidity is typically associated with the subcutaneous port or the band itself. Complications related to band tubing are unusual. Small bowel obstruction (SBO) after LAGB is a unique and serious complication; there is the potential of delayed diagnosis and the risk of closed-loop bowel obstruction. SBO secondary to internal hernia caused by band tubing is very rare, with only five cases reported in the literature. METHODS: In this article, we describe our experience and provide an illustrative video of a case of SBO related to band tubing. We also provide a detailed review of the few previously published case reports. RESULTS: Based on the common features of our case and other published case reports, we hypothesize some risk factors that might lead to this unique morbidity of adjustable gastric band tubing and provide potential solutions to prevent this problem. CONCLUSION: Tubing-related SBO is a serious complication with the risk of closed-loop bowel obstruction. Urgent operative exploration is required to avoid bowel strangulation. To prevent recurrence we advise functionally shortening the tubing by tucking it to the right upper quadrant above the liver and also provide some omental coverage between the bowel and band tubing if possible.

Simultaneous colorectal and hepatic procedures for colorectal cancer result in increased morbidity but equivalent mortality compared with colorectal or hepatic procedures alone: outcomes from the National Surgical Quality Improvement Program.

BACKGROUND: Simultaneous colorectal and hepatic surgery for colorectal cancer (CRC) is increasing as surgery becomes safer and less invasive. There is controversy regarding the morbidity associated with simultaneous, compared with separate or staged, resections. METHODS: Data for 2005-2008 from the National Surgical Quality Improvement Program (NSQIP) were used to compare morbidity after 19,925 colorectal procedures for CRC (CR group), 2295 hepatic resections for metastatic CRC (HEP group), and 314 simultaneous colorectal and hepatic resections (SIM group). RESULTS: An increasing number of simultaneous resections were performed per year. Fewer major colorectal and liver resections were performed in the SIM than in the CR and HEP groups. Patients in the SIM group had a longer operative time and postoperative length of stay compared with those in either the CR or HEP groups. Simultaneous procedures resulted in higher rates of postoperative morbidity and major morbidity than CR procedures, but not HEP procedures. This difference was driven by higher rates of wound and organ space infections, and a greater incidence of septic shock. Mortality rates did not differ among the groups. CONCLUSIONS: Hospitals in the NSQIP are performing more simultaneous colonic and hepatic resections for CRC. These procedures are associated with increases in operative time, length of stay and rate of perioperative complications. Simultaneous procedures do not, however, increase perioperative mortality.
