RESUMEN

OBJECTIVE: This study aimed to investigate perineal wound healing rates following abdominoperineal resection (APR) or extralevator abdominoperineal excision (ELAPE) for rectal cancer, with a focus on identifying associated risk factors and outcomes. METHODOLOGY: A retrospective analysis was conducted on patients undergoing APR or ELAPE for rectal cancer in a tertiary centre between 2013 and 2020. Data on demographics, comorbidities, surgical techniques, and perineal wound outcomes were collected and analyzed using Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 27.0, Armonk, NY). Statistical significance was set at p<0.05. RESULTS: A total of 87 patients were included, with a mean age of 64 years and the majority being male (66.7%). Neoadjuvant radiotherapy was administered in 87.4% of cases. Perineal wound complications were documented in 52 cases (59.8%), with major complications observed in 11 cases (12.6%). Healing within six months was achieved in 48 patients (55.2%), while 39 patients (44.8%) developed chronic perineal wounds. Logistic regression analysis revealed omentoplasty as a significant predictor of perineal wound healing rate showing a significant negative association (p=0.0289). CONCLUSION: Perineal wound healing rates following APR or ELAPE varied. While most patients achieved complete healing, chronic perineal wounds presented challenges. Omentoplasty was associated with lower odds of healing, suggesting the need for further investigation into its role. These findings underscore the importance of patient counselling and multidisciplinary management strategies to optimize outcomes in rectal cancer surgery.

RESUMEN

Omentoplasty, a surgical technique utilizing the omentum's unique properties, has become a pivotal intervention across various surgical fields. This comprehensive review explores the historical evolution, techniques, applications, outcomes, and complications associated with omentoplasty. With its rich vascular supply, lymphatic tissue, and remarkable immunological properties, the omentum has proven invaluable in enhancing wound healing, controlling infections, and providing mechanical support in complex surgical scenarios. The review delves into the anatomy and physiology of the omentum, elucidating its role in promoting angiogenesis and combating infections. Different omentoplasty techniques, including open, laparoscopic, and robotic-assisted approaches, are compared with regard to indications, procedural steps, and outcomes. The applications of omentoplasty span general surgery, cardiothoracic surgery, neurosurgery, gynecologic surgery, and urologic surgery, highlighting its versatility and broad clinical relevance. Short-term and long-term outcomes of omentoplasty, including postoperative recovery, complication rates, recurrence rates, and quality of life, are thoroughly analyzed. The review addresses common and rare complications, emphasizing prevention and management strategies to optimize patient outcomes. Innovations in surgical techniques, the use of biomaterials, and the potential for synthetic or bioengineered omentum are discussed, underscoring the future directions and research opportunities in this field. By providing a detailed examination of omentoplasty, this review aims to enhance understanding, guide clinical practice, and inspire future research to further improve surgical outcomes and patient care.

RESUMEN

BACKGROUND: Despite the minimally invasive approach and early rehabilitation, abdominal-perineal resection (APR) remains a procedure with high morbidity, notably due to postoperative trapped bowel ileus and perineal healing complications. Several surgical techniques have been described for filling the pelvic void to prevent abscess formation and ileus by trapped bowel loop. OBJECTIVE: The aim of our study was to compare the post APR complications for cancer of two of these techniques, omentoplasty and cecal mobilization, in a single-center study from an expert colorectal surgery center. PATIENTS: From 2012 to 2022, 84 patients were included, including 58 (69%) with omentoplasty and 26 (31%) with cecal mobilization. They all underwent APR at Bordeaux University Hospital Center. SETTINGS: A propensity score was used to avoid confounding factors as far as possible. Patient and procedure characteristics were initially comparable. RESULTS: The 30-day complication rate was significantly higher in the cecal mobilization group (53.8% vs. 5.2% p < 0.01), as was the rate of pelvic abscess (34.6% vs. 0% p < 0.001). CONCLUSION: These findings suggest that, when feasible, omentoplasty should be considered the preferred method for pelvic reconstruction following APR.

RESUMEN

Lymphocele formation is a rare complication after surgical procedures involving the mediastinum. While uncomplicated lymphoceles show high rates of spontaneous closure and are usually treated conservatively, surgical treatment might be required in cases with persistent or recurrent lymphoceles. We present the case of a 53-year-old male with reoccurring cervical swelling after two surgeries of the thoracic aorta. After 1.5 years, the swelling occurred for the first time and appeared for the next 2 years repeatedly without clinical or laboratory signs of infection. A cervical lymphocele was suspected, and the decision for surgical revision was made. Fibrin glue was applied to the potential leakage of the thoracic duct, and the cavity was filled with a free omental flap. This resulted in a complete regression of the swelling.

RESUMEN

INTRODUCTION AND IMPORTANCE: Acute appendicitis is a common cause of acute abdomen worldwide. The complications associated with it can sometimes be unpredictable and pose a dilemma in the management of such complications. CASE PRESENTATION: A case of 18 year female with complaints of right iliac fossa pain and vomiting was diagnosed clinically as acute appendicitis and underwent emergency open appendectomy where a cecal perforation was encountered intra-operatively for which a Modified Graham's Patch Repair was done. CLINICAL DISCUSSION: Acute appendicitis can sometimes present with complications like perforation, among which cecal perforation is rare and difficult to diagnose in the initial setting. Perforated appendicitis or colon can increase morbidity and mortality significantly. High degree of suspicion and early surgical approach can lead to identification of rare complications, which can still pose a surgical dilemma on the approach of management. CONCLUSION: Cecal perforation in suspected acute appendicitis is a rarely encountered intra operative complication. Management approaches can range from less invasive suture with omental patch repair to more invasive right hemicolectomy.

RESUMEN

Background No consensus exists regarding surgical intervention for rheumatoid nodule-related pneumothorax. Clinical policy decisions rely on individual clinicians' experience and are usually intractable. Case Description A 50-year-old man with a difficult-to-treat rheumatoid arthritis-related pneumothorax was successfully treated with pedicle omentoplasty without recurrence at approximately 2 years posttreatment. To the best of our knowledge, this is the first report of a patient where pneumothorax did not recur due to firm adhesions despite fluctuating postoperative rheumatoid nodules, as captured by regular computed tomography imaging follow-ups. Conclusion Pedicled omentoplasty is effective for rheumatoid nodule-related pneumothorax as it reduces pneumothorax recurrence.

RESUMEN

Radiation-induced brachial plexopathy (RIBP) is a rare long-term complication of radiation therapy often causing pain, motor deficit, and overall quality of life reduction for affected patients. While a standard treatment for RIBP is yet to be established, management consists mostly of symptom management through the use of medications and physical therapy. There is a lack of evidence regarding the efficacy of surgical treatment. Omentoplasties and other vascularized flaps are commonly discussed options for eliminating neuropathic pain associated with RIBP. However, these approaches show no meaningful improvement in motor function. While limited, current literature suggests that nerve transfers may be an option for relief of neuropathic pain as well as restoration of motor function. This review of literature explores the options available to those affected by RIBP with a focus on the role of surgery.

RESUMEN

BACKGROUND: Omental Infarction (OI) is uncommon and mimics common causes of acute abdomen. It is important to differentiate it from other abdominal conditions that require emergency management. It was first reported in literature in 1896 and about 400 cases have been reported till date. CASE PRESENTATION: We reported on a 41 year-old Para 0+0 Ibo house wife who presented with 10 years history of supra-pubic mass and five months history of excessive menstrual flow. After physical examination, a diagnosis of symptomatic uterine fibroid was made. She had myomectomy and the raw surface created after the excision of the myomas was covered with omentum. Wound infection developed on the 8th post-operative day leading to a wound breakdown and later partial extrusion of infarcted omental tissue through the dehisced wound. During re-exploration, the infarcted omental tissue was extracted and the residual abdominal abscess was drained. Surgical site wound infection occurred on the 3rd day after re-operation and a sub-acute intestinal obstruction developed on the 4th day thereafter which responded to conservative management. CONCLUSION: Careful surgical technique is imperative when utilizing the omentum for reconstructive abdominal surgery. Torsion of the omentum and creation of excess tension while using the omentum for reconstructive procedures should be avoided and increase awareness of this uncommon disease condition by the surgeon is also important. This case is to report a rare finding of omental infarction following myomectomy.

RESUMEN

Chest wall chondrosarcoma is a rare malignant tumor with aggressive biological behavior. The only available treatment for primary or recurrent chondrosarcoma consists of radical surgical resection because of its well-known chemo- and radioresistance. Repeated resection for recurrent chondrosarcoma is challenging because of the altered anatomy, scarring, harvested muscles, and close proximity to vital thoracic organs. We present an uncommon case of recurrent chest wall chondrosarcoma resected in the Department of Thoracic Surgery, which we reconstructed with Symbotex mesh and reinforced by omentoplasty. In addition, we created a brief review of the prevalence, diagnostics, surgical treatment, reconstructive options, and prognosis for this condition.

RESUMEN

Minimally invasive surgeries have been developed, not only for gastrointestinal cancer, but also for benign or emergency cases. We report the case of a 62-year-old male who underwent laparoscopic and thoracoscopic combined surgery for an esophago-mediastinal fistula caused by a press-through package. In the initial laparoscopic phase, transhiatal dissection of the lower thoracic esophagus and harvesting of the greater omentum were performed. In the thoracoscopic phase, resection of the fistula and esophageal wall closure were performed. Thereafter, the greater omentum was lifted via the esophageal hiatus and wrapped around the repaired part of the esophagus for reinforcement. The total operative time was 371 min, with 163 and 208 min for the laparoscopic and thoracoscopic phases, respectively. In total, 20 ml of blood was lost. No perioperative complications or recurrences were observed. Laparoscopic and thoracoscopic combined omentoplasty was effective for refractory esophago-mediastinal fistula.

RESUMEN

Introduction: A bronchopleural fistula (BPF) after an anatomical lung resection commonly arises singly. We report a case of a metachronous BPF, which developed after omentoplasty of a preceding fistula and subsequently closed without any intervention. Case presentation: A 77-year-old patient underwent omentoplasty for a brochopleural fistula (BPF) following a right lower lobectomy. A sudden massive air leak developed from the novel BPF approximately 1 cm proximal to the preceding fistula 3 days later. The air leak resolved spontaneously without any intervention one week later. The corresponding fistula was found to be completely closed. Computed tomography showed the omental flap covered both fistulae. Conclusion: The present case suggested that a metachronous BPF could develop and a harvested omental flap might migrate even after being anchored.

RESUMEN

BACKGROUND: Anastomotic leaks (AL) remain a devastating complication following intestinal anastomoses resulting in increased morbidity and mortality. Wrapping the anastomosis with omentum may be protective although data are conflicting. We performed a meta-analysis to assess the effect of omentoplasty on colorectal anastomoses. METHODS: PubMed, EMBASE and Cochrane databases were searched for relevant articles from inception until August 2021. All randomized controlled trials (RCT) that reported on the use of omentoplasty in colon and rectal surgery were included. The primary outcome was rate of overall AL while secondary outcomes included clinical and radiological AL, overall reoperation and mortality. Random effects models were used to calculate pooled effect size estimates. Sensitivity analyses were also performed. RESULTS: Four RCTs were included capturing 1067 patients. The mean (SD) age of the cohort was 61.5 (±14.8) years. On random effects analysis, omentoplasty reduced rate of overall (OR 0.43, 95% CI = 0.21-0.87, p = 0.02) and clinical AL (OR = 0.35, 95% CI = 0.15-0.81, p = 0.01). However, there was no difference in radiological AL (OR = 0.77, 95% CI = 0.40-1.47, p = 0.42), overall reoperations (OR 0.48, 95% CI = 0.18-1.32, p = 0.16) or mortality (OR 0.52, 95% CI = 0.12 to-2.18, p = 0.37). On sensitivity analysis, assessing rectal anastomoses only, the results for overall AL remained similar (OR 0.28, 95% CI = 0.12-0.61, p = 0.002). CONCLUSION: Although omentoplasty appears to reduce the rate of overall and clinical AL, the heterogeneity in the data prevents definitive recommendations from being made. Further well-designed trials are needed to investigate this technique.

RESUMEN

Incidence of postoperative sternomediastinitis depends on various risk factors and makes up 8%. Surgical debridement with local management of the wound are used to achieve wound sterility. In some cases, sternectomy or subtotal sternal resection are performed for total sternal osteomyelitis with osteoporotic bone and multiple fractures. This procedure results an extensive bone defect. The final stage is anterior chest wall reconstruction. The most popular method is wound closure with autologous muscle or omental flaps. The authors describe a patient with sternomediastinitis who underwent staged treatment. At the final stage, subtotal sternectomy with simultaneous omentoplasty were performed. Additionally, mammary-gastroepiploic bypass grafting with right internal mammary artery and right gastroepiploic artery was carried out for additional vascularization of the omental flap. We found no similar surgery for sternomediastinitis in the literature. Long-term treatment outcome was followed-up (>50 months of relapse-free period and good quality of life).

RESUMEN

Complex chest and lung infections with bronchial fistula are life-threatening situations with a mortality rate of up to 20%. If medical treatment fails, these patients require aggressive procedures to heal. Transposition of the omentum is a valuable, nonstandard option in these complex cases with aggressive infection involving the pleural space, with or without a bronchial fistula, when medical treatment is unsuccessful. We present a 29-year-old female patient diagnosed with primary immunodeficiency and invasive fungal infection with involvement of the left upper lobe and mediastinal and vertebral bodies treated with a lobectomy and intrathoracic transposition of the omentum.

RESUMEN

We report a comorbid patient after redo Frozen Elephant Trunk procedure followed by recurrent infection of thoracic aortic prosthesis, deep sternal wound infection and extensive soft tissue defect. Closure with skin-muscle thoracodorsal flap and graft-sparing technique with omentoplasty is an alternative to total graft replacement for thoracic aortic graft infection in comorbid patients with concomitant extensive defect of the chest wall or recurrent infection in early postoperative period.

RESUMEN

OBJECTIVE: To assess the possibilities of omentoplasty for prevention of complications after redo sternum osteosynthesis for traumatic rupture. MATERIAL AND METHODS: The study included 53 patients with recurrent sternal diastasis. Greater omentum was additionally implanted in 19 (35.8%) cases to improve healing and reduce the risk of infectious complications. In 34 patients, redo osteosynthesis was carried out using a metal wire and deployment of irrigation-aspiration system. In 19 patients, omentoplasty was additionally used to close the wound. RESULTS: Omentoplasty was characterized by less duration of lavage (7.4±1.5 vs. 4.2±3.3 days, p<0.0001) and no cases of arrosive bleeding (p=0.04). CONCLUSION: Omentoplasty reduces duration of treatment and risk of arrosive bleeding.

RESUMEN

BACKGROUND: Hepatic cysts in located posterior segments close to the diaphragm (IVa, VII, and VIII) reportedly have a high recurrence rate. Presently, laparoscopic omentoplasty is the accepted technique; developed from laparoscopic deroofing, which places a viable pedicle flap of omentum to prevent cyst closure. However, potential adhesions have made laparoscopic omentoplasty less favorable. In this paper, we report on an improved surgical technique involving lauromacrogol sclerosis directly under laparoscopic fenestration. We also review and evaluate the efficacy and feasibility of this refined surgical approach. METHODS: Data from 49 patients admitted to the Department of Hepatobiliary Surgery at the Affiliated Hospital of Jiangnan University from October 2015 to June 2020 with simple hepatic cysts located in the IVa, VII, and VIII segments were retrospectively analyzed. All patients were symptomatic before admission. They were separated into two groups based on the surgical approach they had received; refined laparoscopic lauromacrogol sclerotherapy or laparoscopic omentoplasty, and were compared and evaluated in terms of the postoperative cyst volume and quality of life. RESULTS: No significant differences in sex, age, preoperative cyst volume, surgery duration, hospital stay, and bleeding volume were reported. There were no deaths or major complications in both groups. The postoperative cyst volume was significantly reduced in the laparoscopic lauromacrogol sclerotherapy group (2.48 cm) compared to the laparoscopic omentoplasty group (3.90 cm). This study evaluated both the immediate and medium-term results with a 3-12 months follow-up period for all patients. The cyst volume change in the laparoscopic lauromacrogol sclerotherapy group was found to be significantly greater than that of the laparoscopic omentoplasty group. The feedback regarding quality of life did not vary significantly between the two groups, except for general health and health change, where patients who received laparoscopic sclerotherapy responded with higher scores. CONCLUSIONS: Our results indicate that laparoscopic lauromacrogol sclerotherapy surgery was safe and effective in patients with IVa, VII and VIII segment simple hepatic cysts.

RESUMEN

BACKGROUND: Omentoplasty is sometimes used to prevent perineal wound complications after abdominoperineal resection (APR) following neoadjuvant chemoradiotherapy (NACRT). However, recent studies have raised some controversy about its clinical benefit. PATIENTS AND METHODS: Outcomes for rectal cancer patients who received APR after NACRT were retrospectively compared between the groups with omentoplasty (n=28) and without omentoplasty (n=14). RESULTS: The operative time was significantly longer in the omentoplasty group (575 vs. 404 min, p<0.001). Laparoscopic surgery was performed more frequently in the omentoplasty group. Perineal wound problems including dehiscence and infection were significantly reduced in the omentoplasty group (46.4% vs. 78.6%, p<0.001). Univariate and multivariate analyses revealed that omentoplasty was the most important factor in reducing perineal wound complications (odds ratio=0.020, 95% confidence intervaI=0.001-0.393; p=0.001). CONCLUSION: Omentoplasty was useful in reducing perineal wound complications after APR following NACRT.

RESUMEN

AIM: Pelviperineal wound complications frequently occur after salvage surgery for chronic pelvic sepsis despite using an omentoplasty. Sufficient perfusion of the omentoplasty following mobilization is essential for proper healing. This study investigated the impact on short-term clinical outcomes of fluorescence angiography (FA) using indocyanine green for assessment of omental perfusion in patients undergoing salvage surgery. METHOD: This was a comparative cohort study including consecutive patients who underwent combined abdominal and transanal minimally invasive salvage surgery with omentoplasty at a national referral centre for chronic pelvic sepsis between December 2014 and August 2019. The historical and interventional cohorts were defined based on the date of introduction of FA in April 2018. The primary outcome was pelviperineal non-healing, defined by the presence of any degree of pelviperineal infection at the final postoperative evaluation. RESULTS: Eighty-eight patients underwent salvage surgery with omentoplasty for chronic pelvic sepsis, of whom 52 did not have FA and 36 did have FA. The underlying primary disease was Crohn's disease (n = 50) or rectal cancer (n = 38), with even distribution among the cohorts (P = 0.811). FA led to a change in management in 28/36 (78%) patients. After a median of 89 days, pelviperineal non-healing was observed in 22/52 (42%) patients in the cohort without FA and in 8/36 (22%) patients in the cohort with FA (P = 0.051). Omental necrosis was found during reoperation in 3/52 and 0/36 patients, respectively (P = 0.266). CONCLUSION: After introduction of FA to assess perfusion of the omentoplasty, halving of the pelviperineal non-healing rate was observed in patients undergoing salvage surgery for chronic pelvic sepsis.
