RESUMEN

Anastomotic leakage and subsequent pelvic sepsis are serious complications after surgery for pelvic malignancies, particularly challenging due to the large pelvic cavity dead space post-exenteration. We report a 47-year-old man treated for a severely infected pelvic hematoma and sepsis following anastomotic leakage after anterior pelvic exenteration. Post robot-assisted exenteration for locally advanced sigmoid colon cancer treated with neoadjuvant chemotherapy, a pelvic abscess from anastomotic dehiscence was identified. Initial CT-guided drainage and subsequent laparoscopic drainage were performed. On postoperative day 22, a bleeding left internal iliac pseudoaneurysm required embolization. Despite these efforts, the sepsis worsened due to an enlarged, infected hematoma. Endoscopic lavage, in collaboration with skilled endoscopists, successfully removed the hematoma, leading to an improved inflammatory response, and the patient was discharged. Endoscopic lavage proved to be the safest and most effective treatment for pelvic sepsis with an infected hematoma after various attempted interventions.

RESUMEN

Bariatric surgery is a safe and effective treatment option for patients with obesity and obesity-related comorbidities, with Roux-en-Y gastric bypass and sleeve gastrectomy being the two most common procedures. Despite the success of these interventions, adverse events are not uncommon. Endoscopic management has become first-line therapy when complications occur, and the armamentarium of devices and techniques continues to grow. This article focuses on the management of fistulas, leaks, and ulcers and also focuses on the etiology and endoscopic management strategy of each complication.

RESUMEN

CASE PRESENTATION: A 70-year-old man was diagnosed with mid-thoracic esophageal squamous cell carcinoma (distance from incisors, 27-30 cm) because of progressive dysphagia and underwent thoracic laparoscopic esophagectomy at a local hospital. He was transferred from the ICU 4 days after surgery; however, a large amount of purulent fluid exuded from the neck incision after oral drinking, which was consistent with cervical anastomotic leakage. Later, the patient experienced difficulty breathing and expelling sputum; he was then transferred back to the ICU for treatment. A CT scan showed massive fluid collection in the mediastinum and left pleural cavity. Thoracentesis yielded yellowish fluid, and the patient's general condition gradually improved after placement of a closed chest drainage system. The patient's cervical anastomotic fistula persisted and did not heal, and he was subsequently transferred to our medical center with the closed chest drainage system left in place.

RESUMEN

Late perforation of the ileum is a rare and potentially life-threatening complication following intestinal resection. We present a unique case of a woman in her 60s with a history of appendiceal carcinoid tumour, who underwent a right hemicolectomy. Positron emission tomography and surveillance CTs showed normal surgical changes and no recurrent malignancy. Three years postoperatively, she presented with severe abdominal pain. CT revealed a perforation along the ileal wall of the ileocolonic anastomosis. She underwent emergent resection and repeat ileocolonic anastomosis. We conclude that the patient had subclinical ischaemia of the anastomosis, which eventually progressed to perforation 3 years later. We discuss a literature review on late small intestinal anastomotic perforations and their associated risk factors. Our case and literature review emphasise the importance of considering delayed anastomotic leak in postoperative patients with a history of intestinal cancer, inflammatory bowel disease, Roux-en-Y enteroenterostomy or side-to-side anastomosis.

RESUMEN

BACKGROUND: Metabolic bariatric surgery (MBS) is standardized and safe. Nevertheless, complications such as anastomotic leakage (AL) or staple-line leakage (SLL) can occur. In upper GI or colorectal surgery, endoluminal vacuum therapy (EVT) offers a therapeutic alternative to revisional surgery. Data on EVT in patients with leakage after MBS remain scarce. The aim of this study is to evaluate the efficacy of EVT and its potential as endoscopic alternative to revisional surgery. MATERIAL AND METHODS: All patients treated for AL or SLL with EVT after MBS between 01/2016 and 08/2023 at the Department for General Surgery, Medical University Vienna, were included in this retrospective, single-center study. Therapeutic value of EVT as management option for acute postoperative leakage after MBS in daily practice was evaluated. Statistical analyses were performed descriptively. RESULTS: Twenty-one patients were treated with EVT within the observational period of 7 years. In 11 cases (52.4%), the index surgery was a primary bariatric intervention; in 10 cases (47.6%), a secondary surgery after initial MBS was performed. Favored approach was a combination of revisional surgery and EVT (n = 18; 85.7%), intermediate self-expanding metal stent (SEMS) in 16 (76.2%) cases. EVT was changed six times (0-33) every 3-4 days. Mean EVT time was 25.1 days (3-97). No severe associated complications were detected and EVT showed an efficacy of 95.2%. CONCLUSION: This small case series supports the trend to establish EVT in daily clinical practice when revisional surgery after MBS is needed, thus preventing further reoperation and reducing associated morbidity and mortality in critically ill patients.

RESUMEN

Sleeve gastrectomy (SG) is widely recognized as the leading bariatric procedure worldwide. However, leakage, its major complication, remains a significant concern. This study focuses on the challenges of managing leakage, especially when conventional endoscopic treatments are ineffective. Although a novel one-step approach as reported by Pulimuttil James Zachariah from Wei-Jei Lee's team has demonstrated promise, further investigations and reports on its efficacy are currently insufficient. Between January 2021 and November 2023, we analyzed five patients treated at our center for SG leakage. Patient data include demographics, comorbidities, surgical details, and outcomes. The study details Laparo-Endoscopic Gastrostomy procedures performed post-SG leakage diagnosis, highlighting differences between acute and chronic instances. The study effectively implemented Zachariah's one-step approach, achieving favorable results in all five cases. Patient characteristics, presentation, postoperative progression, and additional treatments were documented. The outcome supports Zachariah's assertion that the one-step approach is a simple, safe, and cost-effective approach for SG leakage, avoiding digestive tract reconstruction. Despite potential limitations, including challenges in closing large defects and extended healing times, the procedure's effectiveness in decompression, drainage, and nutritional support significantly contributes to its elevated healing rate. The study emphasizes the importance of timely abdominal drain removal based on clinical conditions, challenging traditional practices for better clinical outcomes.

RESUMEN

PURPOSE: The surgical indication of thoracoscopic primary repair for esophageal atresia with tracheoesophageal fistula is under debate. The current study aimed to investigate the outcome of thoracoscopic primary repair for esophageal atresia with tracheoesophageal fistula in patients weighing < 2000 g and those who underwent emergency surgery at the age of 0 day. METHODS: The surgical outcomes were compared between patients weighing < 2000 g and those weighing > 2000 g at surgery and between patients who underwent surgery at the age of 0 day and those who underwent surgery at age ≥ 1 day. RESULTS: In total, 43 patients underwent thoracoscopic primary repair for esophageal atresia with tracheoesophageal fistula. The surgical outcomes according to body weight were similar. Patients who underwent surgery at the age of 0 day were more likely to develop anastomotic leakage than those who underwent surgery at the age of ≥ 1 day (2 vs. 0 case, p = 0.02). Anastomotic leakage was treated with conservative therapy. CONCLUSION: Thoracoscopic primary repair is safe and useful for esophageal atresia with tracheoesophageal fistula even in newborns weighing < 2000 g. However, emergency surgery at the age of 0 day should be cautiously performed due to the risk of anastomotic leakage.

RESUMEN

While the endoscopic management of surgical complications like leaks, fistulas, and perforations is rapidly evolving, its core principles revolve around closure, drainage, and containment. Effectively managing these conditions relies on several factors, such as the underlying cause, chronicity of the lesion, tissue viability, co-morbidities, availability of devices, and expertise required to perform the endoscopy. In contrast to acute perforation, fistulas and leaks often demand a multimodal approach requiring more than one session to achieve the required results. Although the ultimate goal is complete resolution, these endoscopic interventions can provide clinical stability, enabling enteral feeding to lead to early hospital discharge or elective surgery. In this discussion, we emphasize the current state of knowledge and the prospective role of endoscopic interventions in managing surgical complications.

RESUMEN

PURPOSE: The long-term outcomes of patients with staple line leaks (SLL) after SG are under-reported. The purpose of this study is to evaluate the long-term outcomes of patients with SLL after SG. MATERIALS AND METHODS: A retrospective analysis of a maintained patient registry of patients undergoing SG between January 2012 and December 2020 in a single bariatric center was analyzed and included patients with SLL. Outcomes were compared to a group without SLL. RESULTS: During this period, 1985 patients underwent SG of which 61 patients (3.1%) developed leak. 26 patients (1.3%) had overt SLL and the rest had organ space infection around the staple line. The mean age and body mass index (BMI) were 39.8 ± 11.3 and 41.5 ± 4.7, respectively. 7 patients (11.4%) underwent concomitant surgery and 12 patients (19.7%) had intraoperative complications. Leak was complicated by Clavien-Dindo ≥ 3 in 31 patients (50.8%). Reoperation rate was 27.8% (n = 17). ≥ 2 interventions were required in 26% of patients (n = 16). Two patients died during hospitalization due to septic complications. Long-term follow-up of median 121 months was available in 78% of the cohort (n = 48). The median total weight loss and BMI were 27% and 30.1 kg/m2, respectively. Weight loss outcomes were higher in comparison to patients without SLL. Seven patients (14.6%) underwent SG revision. All associated medical problems improved during follow-up except for gastroesophageal reflux which was found in 50% of cohort. CONCLUSION: Long-term outcomes of SG patients with SLL are satisfactory in terms of weight loss, resolution of comorbidities, and requirement for surgical revision.

RESUMEN

OBJECTIVE: To investigate usage and utility of routine upper gastrointestinal (UGI) series in the immediate post-operative period to evaluate for leak and other complications. METHODS: Single institution IRB-approved retrospective review of patients who underwent bariatric procedure between 01/08 and 12/12 with at least 6-month follow-up. RESULTS: Out of 135 patients (23%) who underwent routine UGI imaging, 32% of patients were post-gastric bypass (127) versus 4% of sleeve gastrectomy (8). In patients post-gastric bypass, 22 were found with delayed contrast passage, 3 possible obstruction, 4 possible leak, and only 1 definite leak. In patients post-sleeve gastrectomy, 2 had delayed passage of contrast without evidence of a leak. No leak was identified in 443 patients (77%) who did not undergo imaging. The sensitivity and specificity of UGI series for the detection of leak in gastric bypass patients were 100% and 97%, respectively, and the positive and negative predictive values were 20% and 100%, respectively. On univariate and multivariate analysis, sleeve gastrectomy patients (OR 0.4 sleeve vs bypass; P < 0.01) and male patients (OR 0.4 M vs F; P 0.02) were less likely to undergo routine UGI series (OR 0.4 M vs F; P 0.02). CONCLUSION: Routine UGI series may be of limited value for the detection of anastomotic leaks after gastric bypass or sleeve gastrectomy and patients should undergo routine imaging based on clinical parameters. Gastric bypass procedure and female gender were factors increasing the likelihood of routine post-operative UGI. Further larger scale analysis of this important topic is warranted.

RESUMEN

Colorectal surgery poses significant risks, with anastomotic disruption being a severe complication. Traditional management involves surgical intervention, contributing to postoperative morbidity and mortality. In this brief report, we present a 54-year-old woman with a history of diverticulitis, multiple surgeries, and anastomotic leak following ileorectal anastomosis. Attempts at managing anastomotic leaks with more minimally invasive approaches have been successful in esophageal surgery with the use of covered metallic stents. However, this approach has been rarely attempted for the management of colorectal anastomotic leaks. Instead of conventional surgical approaches, we employed an off-label use of an endoscopic covered metallic stent, WallFlex™, to successfully manage the anastomotic disruption. The patient's recovery was uneventful, highlighting the potential role of stents in select cases.

RESUMEN

OBJECTIVE: To assess the possibilities of fluorescent detection system in qualitative and quantitative assessment of bowel perfusion in colorectal resections. MATERIAL AND METHODS: From May to August 2023, a single-center pilot cross-sectional unblinded study with inclusion of 18 patients with colon cancer (of left-sided - 12, of right-sided - 6, mean age - 72.9 years, m/w - 61/39%) was conducted. All patients underwent laparoscopic colorectal resections with extracorporeal stage of bowel transection. The evaluation of the bowel's ICG perfusion was conducted to assist in decision making about the level of its resection. Qualitative (visual) assessment was carried out in all 18 patients, in one patient twice, quantitative assessment of perfusion was conducted in 8 patients (left-sided resections - 6, right-sided hemicolectomy - 2). The qualitative evaluation was performed in real time on the analysis of the color gradient. The time parameters and fluorescence intensity at different level proximally and distally from the resection line were quantitatively estimated: Tstart - time of occurrence of minimal fluorescence in the areas of interest after the ICG injection (sec); Tmax - time to achieve maximum fluorescence intensity after the ICG injection (sec); Tmax-start - time interval between Tstart and Tmax, Imax - level of maximum fluorescence intensity (I). RESULTS: Visual qualitative analysis of fluorescence revealed unsatisfactory perfusion characteristics (black, dark-gray color) in the area planned by the surgeon to anastomose the bowel in 3 of 18 patients (16.6%). When analyzing the quantitative data of this group of patients, there was a 2-6-fold decrease in Imax level, and one patient had an increase in Tmax-start at the level of intended resection compared to the bowel's sections in the favorable zone. In all cases, the final bowel transection was conducted in the area of good perfusion. There was no clinical evidence of anastomotic dehiscence in the study group. CONCLUSION: Intraoperative evaluation of bowel perfusion is an important component of safe anastomosis formation in colorectal surgery. The use of ICG-FA allows to conduct qualitative and quantitative assessment of tissue perfusion of the bowel in order to assist in making intraoperative decisions. Quantitative evaluation of fluorescence provides more objective information about perfusion parameters. Imax and Tmax-start are the most promising quantitative indicators of local bowel's perfusion. Nevertheless, the precise interpretation of the quantitative indicators of ICG perfusion needs to be clarified.

RESUMEN

OBJECTIVE: To investigate overall survival and length of stay (LOS) associated with differing management for high output (>1 L over 24 hours) leaks (HOCL) after cancer-related esophagectomy. BACKGROUND: Although infrequent, chyle leak after esophagectomy is an event that can lead to significant perioperative sequelae. Low-volume leaks appear to respond to nonoperative measures, whereas HOCLs often require invasive therapeutic interventions. METHODS: From a prospective single-institution database, we retrospectively reviewed patients treated from 2001 to 2021 who underwent esophagectomy for esophageal cancer. Within that cohort, we focused on a subgroup of patients who manifested a HOCL postoperatively. Clinicopathologic and operative characteristics were collected, including hospital LOS and survival data. RESULTS: A total of 53/2299 patients manifested a HOCL. These were mostly males (77%), with a mean age of 62 years. Of this group, 15 patients received nonoperative management, 15 patients received prompt (<72 hours from diagnosis) interventional management, and 23 received late interventional management. Patients in the late intervention group had longer LOSs compared with early intervention (slope = 9.849, 95% CI: 3.431-16.267). Late intervention (hazard ratio: 4.772, CI: 1.384-16.460) and nonoperative management (hazard ratio: 4.731, CI: 1.294-17.305) were associated with increased mortality compared with early intervention. Patients with early intervention for HOCL had an overall survival similar to patients without chyle leaks in survival analysis. CONCLUSIONS: Patients with HOCL should receive early intervention to possibly reverse the prognostic implications of this potentially detrimental complication.

RESUMEN

BACKGROUND: Esophagectomy in combination with perioperative multimodal therapy is the cornerstone of modern curative treatment for esophageal adenocarcinoma. The primary aim of this study was to assess the influence of textbook outcome (TO) as a composite quality performance indicator (QPI) and its perioperative parameters on survival in patients who underwent esophagectomy with curative intent. METHODS: Consecutive patients who underwent an esophagectomy between January 2014 and December 2022 at Christchurch Hospital were identified from a prospectively maintained hospital database. Univariable and multivariable analyses were performed to assess prognostic factors for each composite and individual postoperative outcome. Survival analysis was performed to evaluate the influence of these outcomes on overall survival. RESULTS: A total of 108 patients underwent an esophagectomy during the study period. The overall and Clavien-Dindo (CD) grade ≥ 3 postoperative complication rates were 62% and 26%, respectively. The anastomotic leak rate was 6.5% (n = 7). The TO rate, 30-day readmission rate, and 30-day mortality rate were 20%, 13%, and 1%, respectively. Resection margin and nodal disease were found to be independent prognostic factors for reduced survival. CONCLUSION: TO as originally defined and its postoperative parameters of 30-day postoperative complications and 30-day readmission are validated QPIs of esophageal cancer surgery. Updating the postoperative complication parameter to include CD grade ≥ 3 complications resulted in a positive association between achieving TO and increased survival. Our findings support the call to redefine TO based on an update to this parameter, making it a more precise QPI of esophageal cancer surgery.

RESUMEN

PURPOSE: Anastomotic leakage after anterior resection for rectal cancer induces bowel dysfunction, but the influence on urinary and sexual function is largely unknown. This cross-sectional cohort study evaluated long-term effect of anastomotic leakage on urinary and sexual function in male patients. METHODS: Patients operated with anterior resection for rectal cancer in 15 Swedish hospitals 2007-2013 were identified. Anastomotic leakage and other clinical variables were retrieved from the Swedish Colorectal Cancer Registry and medical records. Urinary and sexual dysfunction were evaluated at 4 to 11 years after surgery using the International Prostate Symptom Score, International Index of Erectile Function, and European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire CR29. The effect of anastomotic leakage on average scores of urinary and sexual dysfunction was evaluated as a primary outcome, and the single items permanent urinary catheter and sexual inactivity as secondary outcomes. The association of anastomotic leakage and functional outcomes was analyzed using regression models with adjustment for confounders. RESULTS: After a median follow-up of 84 months (interquartile range: 67-110), 379 out of 864 eligible men were included. Fifty-nine (16%) patients had anastomotic leakage. Urinary incontinence was more common in the leakage group, with an adjusted mean score difference measured by EORTC QLQ ColoRectal-29 of 8.69 (95% confidence interval: 0.72-16.67). The higher risks of urinary frequency, permanent urinary catheter, and sexual inactivity did not reach significance. CONCLUSION: Anastomotic leakage after anterior resection had a minor negative impact on urinary and sexual function in men.
