RESUMO

BACKGROUND: Retrosternal oesophageal reconstructions with collar anastomoses can become necessary when the stomach is either unavailable for oesophageal replacement, or orthotopic reconstruction is deemed impractical. Our aim was to analyse our results regarding technical approaches and outcomes. MATERIALS AND METHODS: All patients undergoing primary and secondary oesophageal retrosternal reconstructions with collar anastomoses at our centre (2019-2023) were retrospectively analysed and individual surgical reconstruction options were presented. RESULTS: Overall, twelve patients received primary (n = 5; 42.7%) or secondary (n = 7; 58.3%) reconstructions; ten with colonic interposition and two with gastric pull-up. Male/female ratio was 4:8; median age 66 years (30-87). Charlson-Comorbidity-Score (CCS) was 5 (1-7); 8/12 patients (67%) had ASA-classification score ≥ 3. We observed no conduit necrosis, but one patient (8.3%) with a leakage of the oesophago-colonostomy which was successfully treated by endoscopic vacuum therapy. Four patients (33.3%) acquired nosocomial pneumonia. Additional drainages for pleural fluid collections were necessary in three patients (25%). Overall comprehensive-complication-index (CCI) was 26.2 (0-44.9). Length-of-stay (LOS) was 22 days median (15-40). There was no 90-days mortality. Overall, CCI during the follow-up (FU) period at median 26 months (16-50) was 33.7 (0-100). 10 out of 12 patients were on sufficient oral nutrition at 12 months FU. CONCLUSION: Primary and secondary oesophageal retrosternal reconstructions encompass diverse entities and typically requires tailored decision-making. These procedures, though rare, are feasible with acceptable complication rates and positive functional outcomes when performed in experienced hands.

RESUMO

The purpose of this study was to investigate the application and efficacy analysis of in situ interposition bypass in complex intracranial aneurysms. This study retrospectively analyzed the clinical data of 21 patients with complex intracranial aneurysms treated with in situ interposition bypass grafting in the Department of Neurosurgery at Tianjin Huanhu Hospital from June 2015 to December 2022. The aneurysms were located in the middle cerebral artery in 16 cases, the anterior cerebral artery in 3 cases, the posterior cerebral artery in 1 case, and the posterior inferior cerebellar artery in 1 case. The interposition graft vessels were taken from the radial artery in 15 cases, the superficial temporal artery in 5 cases, and the occipital artery in 1 case. All patients underwent end-to-end anastomosis with in situ interposition bypass after aneurysm resection, including 13 cases of "I-shaped" type, 5 cases of "V-shaped" type, and 3 cases of "Y-shaped" type. Postoperative digital subtraction angiography (DSA) or computed tomography angiography (CTA) reviews were performed for all the patients, and modified Rankin Scale (mRS) score was used to assess patient prognosis. Three patients developed postoperative basal ganglia infarction and two of them recovered well. One case developed transient incomplete aphasia and one case developed mild hemiparesis, which recovered well after 3 months. The remaining 16 patients did not develop new neurological deficits. Postoperative DSA or CTA showed that the anastomosis of the bypass graft and the graft vessels were patent, and all aneurysms were completely eliminated. Regular postoperative follow-up ranged from 3 to 89 months, and no aneurysm recurred. The percentage of patients with mRS ≤ 2 at the final follow-up was 90.5%. Based on the experience of surgical treatment in our center, in situ interposition bypass technique is a safe and effective option for the treatment of some complex intracranial aneurysms.

RESUMO

BACKGROUND: Esophageal squamous cell carcinoma is characterized by field cancerization, wherein multiple cancers occur in the esophagus, head and neck, and stomach. Synchronous esophageal and colorectal cancers are also encountered with a certain frequency. A good prognosis can be expected if the tumors in both locations can be safely and completely removed. For patients with multiple cancers that occur simultaneously with esophageal cancer, it is necessary to perform a staged operation, taking into consideration the associated surgical invasiveness. It is also necessary to select multidisciplinary treatment depending on the degree of progression of the multiple lesions. We report our rare experience with a staged operation for a patient with synchronous advanced cancers of the esophagus and cecum who had previously undergone total gastrectomy with reconstruction by jejunal interposition for gastric cancer. CASE PRESENTATION: A 71-year-old man with a history of reconstruction by jejunal interposition after total gastrectomy was diagnosed as having multiple synchronous esophageal and cecal cancers. After neoadjuvant chemotherapy, we performed a planned two-stage operation, with esophagectomy and jejunostomy in the first stage and ileocecal resection and jejunal reconstruction with vascular anastomosis in the second. Postoperatively, the patient was relieved without major complications, and both tumors were amenable to curative pathologic resection. CONCLUSIONS: Our procedure reported here may be recommended as an option for staged resection and reconstruction in patients with simultaneous advanced esophageal and cecal cancer after total gastrectomy.

RESUMO

BACKGROUND: In cases of wrist arthritis, proximal row carpectomy (PRC) has been widely utilized and shown favorable long-term outcomes. However, its applicability is limited in cases where arthritis extends to the lunate fossa or capitate. Recently, surgical approaches combining various methods of interposition arthroplasty have been introduced to overcome these drawbacks. The purpose of this study was to perform PRC and interposition arthroplasty with dorsal capsule and acellular dermal matrix(ADM),and analyze the clinical outcomes of these procedures. METHODS: Fourteen cases who underwent PRC and interposition arthroplasty using both dorsal capsular flap and ADM were retrospectively recruited. The researchers assessed the patients' Visual Analog Scale (VAS) pain score, Disabilities of the Arm, Shoulder and Hand (DASH) scores, range of motion (ROM), retear, and radiocarpal distance (RCD). RESULTS: One year post-surgery, both the VAS pain scores, DASH scores, and ROM showed statistically significant improvement compared to before the surgery. Upon reviewing the radiological results, the postoperative mean RCD was 4.8 ± 0.8 mm and one year follow up mean RCD was 3.6 ± 0.5 mm at one year post-surgery. Moreover, in the one year follow-up, there was no observed failure of the allodermis graft in any of the cases. CONCLUSION: The PRC and interposition arthroplasty with ADM demonstrated significantly improved clinical outcomes after surgery, showing a maintain of RCD without graft failure effectively.

RESUMO

BACKGROUND: Microvascular decompression (MVD), the standard surgical approach for hemifacial spasm (HFS), can be divided into the interposition and transposition methods. Although the risk of HFS recurrence following interposition has been reported, there is limited data comparing long-term outcomes between both methods performed by a single surgeon. This study aimed to investigate the efficacy of MVD techniques on HFS by comparing surgical outcomes performed by a single surgeon in a single-center setting. METHODS: A total of 109 patients who underwent MVD were analyzed and divided into the transposition (86 patients) and interposition (23 patients) groups. Postoperative outcomes at 1 month and 1 year were assessed and compared, including rates of spasm relief, complications, and recurrence. RESULTS: Outcome assessment revealed higher rates of early spasm relief in the interposition group (66.3% vs. 100%, transposition vs. interposition, respectively, p = 0.0004), although spasm relief at 1-year postoperatively was comparable between the two groups (84.9% vs. 95.7%, transposition vs. interposition, respectively, p = 0.2929). No significant differences were observed in complication and recurrence rates. Kaplan-Meier analysis demonstrated no significant differences in the duration of spasm resolution by MVD method (p = 0.4347, log-rank test). CONCLUSION: This study shows that both the transposition (Surgicel® and fibrin glue) and interposition (sponge) methods were excellent surgical techniques. The interposition method may achieve earlier spasm resolution compared to the transposition method.

RESUMO

PURPOSE: In primary cholesteatoma patients, incus destruction with an intact and mobile stapes is a frequent finding. Different techniques have been described to restore the ossicular chain, including incus interposition, stapes augmentation and type III tympanoplasty. Controversy about postoperative hearing results in open versus closed surgical techniques exist. METHODS: We performed a retrospective analysis of clinical, surgical and audiometric data of patients with primary cholesteatoma surgery operated between 2010 and 2020, and a mobile stapes and one-stage ossicular reconstruction. Pre- and post-operative audiograms were compared for the different surgical groups, mainly focusing on postoperative air-bone gap. Mastoid pneumatization and ventilation was also considered. RESULTS: The mean postoperative air-bone gap (0.5-4 kHz) of the 126 included patients was 20 dB. Hearing after type III tympanoplasty (26 dB) was worse than incus interposition (19 dB) and stapes augmentation (20 dB). Hearing after an open (23 dB) versus closed (19 dB) surgical technique was significantly different. No improvement in air-bone gap was observed for the higher frequencies. CONCLUSION: A residual postoperative air-bone gap should be considered after primary cholesteatoma surgery with intact and mobile stapes. Incus interposition in closed cavity operation is the optimal situation, but open cavity surgery should not be avoided because of hearing. Extent of the disease is prioritized and poorer ventilation before and after surgery may affect postoperative hearing.

RESUMO

PURPOSE: The purpose of this study was to determine the long-term consequences of trapeziectomy and ligament reconstruction and tendon interposition (LRTI) for trapeziometacarpal osteoarthritis in patients aged less than 56 years. METHODS: A retrospective study was performed to investigate the outcome of trapeziectomy and LRTI with a follow-up period of greater than 5 years in patients aged less than 56 years at the time of surgery. Patients completed the Disabilities of Arm, Shoulder, and Hand (DASH), the Patient-Rated Wrist Evaluation (PRWE), and a 10-point visual analog score for pain (VAS). Objective assessments included thumb opposition, palmar and radial abduction angles, and grip, lateral key, and thumb tip pinch strengths. Radiographic assessments of the thumb carpometacarpal joint were performed in three planes, and the trapezial space and trapezial space to metacarpal height ratios were calculated. RESULTS: Between January 2005 and December 2017, 105 patients were treated. Forty-eight patients with 58 thumbs returned for review. The mean patient age at the time of surgery was 52.5 years, and 96% of the patients were women. The mean follow-up period from surgery was 11 years. The mean VAS score was 1. A significant association was found between younger age at the time of surgery and increased proximal migration of the metacarpal, between high VAS pain scores and high PRWE and DASH scores, weak grip, lateral key pinch and thumb tip pinch strength, and Kapandji score, and between the follow-up period and increasing VAS pain, PRWE, and DASH scores. CONCLUSIONS: Trapeziectomy and LRTI are effective procedures for patients aged less than 56 years. The benefits of surgery should be balanced against the deterioration in the outcome measures of DASH and PRWE and increasing VAS scores with increasing intervals from surgery. TYPE OF STUDY/LEVEL EVIDENCE: Therapeutic IV.

RESUMO

BACKGROUND: There are some major controversies surrounding the use and longevity of pyrocarbon interposition shoulder arthroplasty (PISA). The objective of this study was to investigate the long-term survival and outcomes (minimum 10-year) following PISA for osteoarthritis (OA) in young and active patients. METHODS: This was a retrospective review of prospectively collected data of patients who underwent PISA (InSpyre; Tornier-Stryker) for OA between 2009 and 2012. Arthroplasty survival was known for 71 patients followed longitudinally for a minimum of 10 years. The clinical and radiologic outcomes were assessed in 62 patients (62 shoulders) reviewed with radiographs. The mean age at surgery was 60 years (range, 23-72 years), and 31 shoulders (50%) underwent prior surgery before PISA. The diagnosis was primary osteoarthritis (POA = 29), post-traumatic osteoarthritis (PTOA = 23), and postinstability osterarthritis (PIOA = 10). Clinical failure was defined as repeat surgical intervention involving prosthesis revision. Clinical outcomes were assessed with the Constant score (CS) and Subjective Shoulder Value (SSV). The mean duration of follow-up was 11 ± 0.6 years (range, 10-14 years). RESULTS: Overall, the survival rate was 90% (95% confidence interval [CI] 82.8-96.8) at 5 years and 87% (95% CI 79-94.8) at a 10-year follow-up. Survival was 100% in PTOA (type 1 fracture sequelae) and in PIOA as well as 95% in primary OA with type A glenoid. Revision surgery was significantly higher in biconcave (type B2) glenoid (44%) compared with concentric (type A) glenoid (2%), respectively (P = .002). Among the 7 patients who were revised to reverse shoulder arthroplasty, 5 had painful glenoid erosion and 2 had bipolar (glenoid and humeral) erosion with thinning and finally fracture of the greater tuberosity. Two shoulders with glenohumeral erosion were associated with secondary rotator cuff tears (1 supraspinatus and 1 subscapularis tear). The mean time to revision and revision was 4 ± 1.7 years. Glenoid wear was more often superior (81%) than central (19%), P < .001. For those shoulders not revised, the mean CS and SSV significantly increased from 39 ± 14 to 70 ± 14 points and 34% ± 15% to 75% ± 17%, respectively (P < .001). CONCLUSION: PISA is an efficient and durable surgical procedure for the treatment of young and active patients with post-traumatic OA, postinstability OA, and primary OA with concentric (type A) glenoid erosion, but not for those with biconcave (type B2) glenoid. Biconcave (type B2) glenoid and subscapularis tear or insufficiency are risk factors for failure and revision.

RESUMO

BACKROUND: Trapeziometacarpal osteoarthritis has been treated with interposition of autologous fascia into the trapezial resection cavity to prevent scaphometacarpal impingement with suboptimal results. Autologous fascia may undergo necrosis and gradual shrinkage due to avascularity. We propose vascularization of the interposed fascia using microvascular techniques as a new alternative to achieve a durable graft with sufficient soft tissue volume. PATIENTS AND METHODS: In this retrospective study, 11 surgeries for 8 patients (6 women, 2 men) (5 primary and 6 revision cases) were performed using vascularized fascial grafts from the anterolateral thigh for interposition in the trapezial resection cavity with microvascular anastomosis for revascularization. Subjective assessment included the short version of the Quick Disabilities of the Hand, Shoulder and Arm and patient related hand wrist evaluation scores. Objective assessment included strength and range of motion measurements. Radiographs were obtained preoperatively and at each follow-up visit. An MRI was done at a mean of 19 months postoperatively. RESULTS: The size of the harvested fascial grafts was 2 × 2-3 cm with a thickness of 1.5-2 cm. There were no postoperative complications apart from one seroma in the graft harvest site. The mean clinical and radiologic follow-up was 2 years and 8 months. The procedure provided pain relief PRWHE pain 32 (SD 13)-9 (SD 12), p < 0.0001, increased tip pinch strength 4 kg (SD3)-6 kg (SD2), p < 0.05, and improved overall function PRWHE 60 (SD28)-16 (SD21), p < 0.0001 and QuickDash 50 (SD21)-13 (SD17), p < 0.0001. Radiographs demonstrated maintenance of the scaphometacarpal space, while MRI scans showed the presence of mildly edematous interposed tissue within the resection cavity. CONCLUSIONS: Although technically demanding, vascularized fascia presents an attractive alternative for the treatment of trapeziometacarpal osteoarthritis. It may be particularly advantageous in complex cases requiring revision surgery and in young patients with high functional demands.

RESUMO

INTRODUCTION: In displaced pediatric proximal humerus fractures (PHF), surgical treatment ranges from closed to open procedures. Soft tissue interposition can impede closed reduction, making open techniques necessary. While K-wire fixation and elastic stable intramedullary nailing (ESIN) lead to good results, plate fixation could be an alternative in patients with limited growth potential and highly unstable or insufficiently retained fractures. Only few studies with low sample sizes have assessed plate fixation, yet. In this study, the outcome of pediatric PHFs treated with plate fixation was evaluated. MATERIALS AND METHODS: We present a retrospective case series of 18 patients with open growth plates and unilateral, displaced PHFs, treated with plate fixation. The mean age at trauma was 12.1 years (± 2.4), the mean follow-up was 6.52 years (± 4.37). A mean fracture angulation of 32.3° (± 10.89°) was seen. Postoperative assessments included range of motion, clinical scores [Simple Shoulder Test (SST), Subjective Shoulder Value (SSV), American Shoulder and Elbow Surgeons (ASES) Shoulder Score, Pediatric/Adolescent Shoulder Score (PASS), Disabilities of Arm, Shoulder and Hand (DASH) Score], radiological parameters and subjective satisfaction. RESULTS: All patients showed excellent results in SST (99.4% ± 0.02), SSV (98.3% ± 0.04), ASES-score (100% ± 0) and PASS (0.99 ± 0.01). In the DASH-score, 17 patients had excellent results, one patient showed a good outcome. Fracture healing occurred in all patients without complications. Eight patients complained about bothering scars. Age, gender and fracture morphology did not affect the outcome. Revision surgery after secondary fracture dislocation did not show a worsened outcome compared to primary plate fixation. Physeal growth plate bridging implants did not worsen the outcome. The timing of implant removal within the first 6 months postoperatively did not affect long-term function. CONCLUSION: Plate fixation is a safe option in pediatric patients with limited growth potential and highly displaced PHFs. Plate fixation led to a good to excellent functional outcome, regardless of fracture morphology and implant positioning. A higher invasiveness and the need for implant removal must be considered.

RESUMO

OBJECTIVE: To present long-term results of our laparoscopic intracorporeal ileal ureter replacement (LIUR) cohort, including more complex cases of laparoscopic ileocalycostomy. MATERIAL AND METHODS: We collected records of patients undergoing LIUR. Follow-up included a chemical profile and urine cultures. Imaging consisted of renal ultrasonography, excretory urography, cystography, and computer tomographic or magnetic resonance urography. RESULTS: One hundred and two patients were included. Stricture location was left (46.1%), right (39.2%), or bilateral (14.7%). No open conversion was performed. Seventy-four patients (72.5%) underwent a total ureteral unit removal. The mean operative time was 289.4 (120 - 680) minutes. The estimated blood loss was 185.2 (10-400) mL. Three patients had intraoperative complications, and fifteen had early postoperative complications. The mean postoperative hospital stay was 12.2 (7-35) days. The mean follow-up duration period was 37.7 (12-162) months. Most patients' follow-up was uneventful (88%), and seven patients presented with Grade 2 late complications. CONCLUSIONS: Intracorporeal laparoscopic ileal ureteral replacement in cases of extensive ureteral lesions offers optimal long-term outcomes and a low complication rate. Ileocalycostomy constitutes a viable option in the small group of patients with long proximal ureteral strictures and intrarenal pelvis.

RESUMO

Advanced chemo- and radiotherapy makes it possible to expand the cohort of patients who can undergo surgical treatment for esophageal cancer. Optimization of perioperative approach, diagnosis and modern options for complications reduced early postoperative mortality after esophagectomy. Conduit ischemia with failure of esophageal-gastric or esophageal-intestinal anastomosis is one of the most serious complications. To minimize the risk of anastomotic leakage and graft necrosis in these patients, various methods of intraoperative assessment of graft viability are being investigated. Near-infrared fluorescence imaging with indocyanine green is valuable for real time assessment of graft perfusion. To date, fluorescence imaging is analyzed regarding perfusion of the gastric stalk after esophagectomy. However, there are still few or no data on this method for analysis of colonic conduit perfusion. The absence of plastic material for gastrointestinal reconstruction is the most dangerous moment in case of ischemia and necrosis of colonic graft. We present our first case of delayed retrosternal esophageal repair using intraoperative indocyanine green fluorescence imaging for assessment of conduit perfusion.

RESUMO

BACKGROUND: Inflammatory myofibroblastic tumors (IMTs) of the liver are rare neoplasms. These tumors are difficult to distinguish from other neoplasms by radiological examination, have uncertain evolution, and there is no consensus on the treatment of these lesions. Hilar tumors can involve the portal vein, hepatic artery, bile duct, and spread to the branches of the portal triad, causing obstructive symptoms, occlusive phlebitis, and portal hypertension. Thus, liver transplantation (LT) is an excellent alternative for locally advanced hilar tumors, since it ensures complete tumor resection with free margins. METHODS/RESULTS: We present a literature review and a case report showing a 3-year-old boy with liver IMT invading the hepatic hilum and inferior vena cava, who underwent a successful living donor liver transplantation that required portal vein and vena cava replacement. CONCLUSION: The incidence of hilar IMTs is low and there is no well-established standard treatment. Liver transplantation for a hilar tumor with vascular invasion was acceptable in this case because the radically of the surgery was the key for the cure, and because the tumor was benign in nature.

RESUMO

AIM: Complex perineal fistulas (CPFs) are among the most challenging problems in colorectal practice. Various procedures have been used to treat CPFs, with none being a panacea. Our study aimed to assess the overall success and complication rates after gracilis muscle interposition in patients with CPF. METHOD: PubMed, Scopus and Google Scholar databases were systematically searched until January 2022 according to PRISMA 2020 guidelines. Studies including children <18 years or <10 patients were excluded, as well as reviews, duplicate or animal studies, studies with poor documentation (no report of success rate) and non-English text. An open-source, cross-platform software for advanced meta-analysis openMeta [Analyst]™ version 12.11.14 and Cochrane Review Manager 5.4® were used to conduct the meta-analysis of data. RESULTS: Twenty-five studies published between 2002 and 2021 were identified. The studies included 658 patients (409 women). Most patients had rectovaginal (50.7%) or rectourethral fistulas (33.7%). The most common causes of CPF were pelvic surgery (29.4%) and inflammatory bowel disease (25.2%). A history of radiotherapy was reported in approximately 18% of the patients. 498 (75.7%) patients with CPF achieved complete healing after gracilis muscle interposition. The weighted mean rate of success of the gracilis interposition procedure was 79.4% (95% CI 73.8%-85%, I2  = 75.3%), the weighted mean short-term complication rate was 25.7% (95% CI 18.1-33.2, I2  = 84.1%) and the weighted mean rate for 30-day reoperation was 3.6% (95% CI 1.6-5.6, I2  = 42%). The weighted mean rate of fistula recurrence was 16.7% (95% CI 11%-22.3%, I2  = 61%). CONCLUSION: The gracilis muscle interposition technique is a viable treatment option for CPF. Surgeons should be familiar with indications and techniques to offer it as an option for patients. Given the relatively infrequent use of the operation, referral rather than performance of graciloplasty is an acceptable option.

RESUMO

INTRODUCTION: For patients with cancer or injury of the esophagus, esophagectomy with reconstruction using the stomach (gastric pull-up, GPU) or colon (colonic interposition, CI) can restore function but is associated with high morbidity. We sought to describe the differences in outcomes between the two replacement organs using a national database. METHODS: From ACS-NSQIP, patients who underwent GPU or CI between 2006 and 2020 were identified. Univariate analyses were performed on length of stay, complications, reoperation, readmission, and mortality. Variables with P ≤ 0.2 were included in the multivariate regression. Primary outcomes were 30-day reoperation, readmission, and mortality. Data were assessed using Chi-squared tests and logistic regression. RESULTS: There were 12,545 GPU and 502 CI patients. GPU patients were older with higher BMI, and more likely to be male (80.3% versus 70.3%, P < 0.0001) and white (77.8% versus 69.1%, P < 0.0001). More GPU patients had independent functional status and underlying bleeding disorders, but fewer other preoperative comorbidities than CI patients. On univariate analysis, CI patients had longer hospital stays (13 versus 10 days, P < 0.0001); more reoperations (23.9% versus 14.5%, P < 0.0001); a lower rate of discharge to home (70.9% versus 82.1%, P < 0.0001); and a higher mortality rate (6.2% versus 2.9%, P < 0.0001). On multivariate analysis, CI was associated with increased risk of reoperation but not with readmission or mortality. Reoperation was associated with CI, smoking, chronic wound, hypertension, higher ASA class, contaminated or dirty wound class, and longer operative time. Readmission was associated with female gender, hypertension, and longer operative time. Mortality was associated with age, metastatic cancer, preoperative sepsis, preoperative renal failure, malignant esophageal disease, higher ASA class, incomplete closure, and longer operative time. CONCLUSION: Colonic interposition, although a more difficult option with traditionally worse outcomes, should still be considered for patients requiring esophagectomy if the stomach cannot be used to restore continuity, as differences in outcomes appear to be due to underlying frailty of patients rather than the procedure.

RESUMO

Colonic interposition is an alternative for gastric conduit reconstruction after esophagectomy. Anastomotic leakage (AL) occurs in 15-25% of patients and may be attributed to reduced blood supply after vascular ligation. Indocyanine green fluorescence angiography (ICG-FA) can visualize tissue perfusion. We aimed to give an overview of the first experiences of ICG-FA and AL rate in colonic interposition. This study included all consecutive patients who underwent a colonic interposition between January 2015 and December 2021 at a tertiary referral center. Surgery was performed for the following indications: inability to use the stomach because of previous surgery or extensive tumour involvement, cancer recurrence in the gastric conduit, or because of complications after initial esophagectomy. Since 2018 ICG-FA was performed before anastomotic reconstruction by administration of ICG injection (0.1 mg/kg/bolus), using the Spy-phi (Stryker, Kalamazoo, MI). Twenty-eight patients (9 female, mean age 62.8), underwent colonic interposition of whom 15 (54%) underwent ICG-FA-guided surgery. Within the ICG-FA group, three (20%) AL occurred, whereas in the non-ICG-FA group, three AL and one graft necrosis (31%) occurred (P=0.67). There was a change of management due to the FA assessment in three patients in the FA group (20%) which led to the choice of a different bowel segment for the anastomosis. Mean operative times in the ICG-FA and non-ICG-FA groups were 372±99 and 399±113 minutes, respectively (P=0.85). ICG-FA is a safe, easy and feasible technique to assess perfusion of colonic interpositions. ICG-FA is of added value leading to a change in management in a considerable percentage of patients. Its role in prevention of AL remains to be elucidated.

RESUMO

BACKGROUND: To compare the clinical efficacy of two alimentary tract reconstruction methods-"P"-shape jejunal interposition (PJI) and Roux-en-Y anastomosis after total gastrectomy. METHOD: The following search phrases were utilized to search PubMed, Cochrane Library, Embase, China Academic Journals Network Full-text Database (CNKI), and Wanfang Database as of April 2022: "gastrectomy," "Roux-en-Y," "interposition," "total gastrectomy," and "jejunal interposition." Meta-analysis of the operation time, intraoperative blood loss, complication rate, and postoperative nutritional status of patients was performed using RevMan 5.4 software. RESULTS: A total of 24 studies and 1887 patients were included in the study. Among patients who received a total gastrectomy, the operation time in the PJI group was substantially longer than that in the Roux-en-Y group (WMD = 19.77, 95% CI: 5.84-33.70, P = 0.005). The incidence of postoperative reflux esophagitis in the PJI group was considerably reduced than that in the Roux-en-Y group (OR = 0.39, 95% CI: 0.28-0.56, P < 0.01). The probability of postoperative dumping syndrome in the PJI group was significantly lower than that in the Roux-en-Y group (OR = 0.27, 95% CI: 0.17-0.43, P < 0.01), and the postoperative body mass changes were significantly lower in the PJI group than in the Roux-en-Y group (WMD = 3.94, 95% CI: 2.24-5.64, P < 0.01). The PJI group had substantially higher postoperative hemoglobin, albumin, and total protein levels than the Roux-en-Y group (WMD = 13.94, 95% CI: 7.77-19.20, P < 0.01; WMD = 3.97, 95% CI: 2.58-5.37, P < 0.01; WMD = 5.31, 95% CI: 3.45-7.16, P < 0.01). The prognostic nutritional index was higher in the PJI group than in the Roux-en-Y group (WMD = 9.25, 95% CI: 7.37-11.13, P < 0.01). CONCLUSION: PJI is a safe and effective reconstruction method and is superior to Roux-en-Y anastomosis in the prevention and treatment of postoperative complications and postoperative nutritional recovery in patients after total gastrectomy.

RESUMO

INTRODUCTION: The use of antiplatelet (AP) and anticoagulation (AC) therapy after autogenous vein repair of traumatic arterial injury is controversial. The hypothesis in this study was that there is no difference in early postoperative outcomes regardless of whether AC, AP, both, or neither are used. METHODS: The American Association for the Surgery of Trauma (AAST) PROspective Observational Vascular Injury Treatment (PROOVIT) registry was queried from November, 2013, to January, 2019, for arterial injuries repaired with a vein graft. Demographics and injury characteristics were compared. Need for in-hospital reoperation was the primary outcome in this four-arm study, assessed with two ordinal logistic regression models (1. no therapy vs. AC only vs. AC and AP; 2. no therapy vs. AP only vs. AC and AP). RESULTS: 373 patients (52 no therapy, 88 AP only, 77 AC only, 156 both) from 19 centers with recorded Injury Severity Scores (ISS) were identified. Patients who received no therapy were younger than those who received AP (27.0 vs. 34.2, p = 0.02), had higher transfusion requirement (p < 0.01 between all groups) and a different distribution of anatomic injury (p < 0.01). After controlling for age, sex, ISS, platelet count, hemoglobin, pH, lactate, INR, transfusion requirement and anatomic location, there was no association with postoperative medical therapy and in-hospital operative reintervention, or any secondary outcome, including thrombosis (p = 0.67, p = 0.22). CONCLUSIONS: Neither AC nor AP alone, nor in combination, impact complication rate after arterial repair with autologous vein. These patients can be safely treated with or without antithrombotics, recognizing that this study did not demonstrate a beneficial effect.

RESUMO

OBJECTIVES: to compare hearing outcomes between endoscopic transcanal rebridging with bone cement and endoscopic transcanal incus interposition in patients with incus long process defects secondary to chronic suppurative otitis media (inactive mucosal type). METHODS: This retrospective study was performed on 83 ears of 83 consecutive patients with incus long process defects secondary to chronic suppurative otitis media (inactive mucosal type). According to the extent of incus long process erosion and subsequent ossiculoplasty technique, patients were divided into 2 groups. Patients in group 1 had erosion involving up to two thirds of the length of the incus long process and underwent endoscopic transcanal rebridging with bone cement. Patients in group 2 had erosion involving more than two thirds of the length of the incus long process and underwent endoscopic transcanal incus interposition. RESULTS: Hearing gain (mean ± standard deviation) was 21.39 ± 2.15 dB in group 1 and 19.71 ± 6.12 dB in group 2. A significantly greater hearing gain was achieved in bone cement group than in incus interposition group (P value < 0.001). Successful hearing outcome (post-operative air bone gap closure within 20 dB) was achieved in 81.6% and 71.1% of patients of group 1 and group 2 respectively. CONCLUSION: Endoscopic transcanal rebridging with bone cement offers greater hearing gain than endoscopic transcanal incus interposition. The two techniques remain reliable and cost-effective techniques in management of patients with incus long process defects. The main limitation of this study was the short follow-up period. Further studies with relatively long-term follow-up are strongly recommended.

RESUMO

PURPOSE: To describe the surgical procedure of exclusive endoscopic ossiculoplasty (EEO) with autologous grafts and evaluate audiological results, focusing on the advantages or drawbacks compared to the corresponding microscopic technique. METHODS: A retrospective review of consecutive adult and pediatric patients affected by chronic otitis media (COM) with or without cholesteatoma who underwent EEO was conducted. Only autologous ossiculoplasty was included in the study. The procedure was performed by experienced surgeons of our institution between November 2014 and September 2019. Hearing outcomes were evaluated using postoperative air-bone gap (ABG) and success rates in different subgroups of patients and different types of ossiculoplasty (OPL) were analyzed. Our results were finally compared with the existing literature regarding both microscopic and endoscopic ossicular chain reconstruction. RESULTS: In total, 74 endoscopic ossicular chain repair procedures performed within the study period met the inclusion criteria. Of these, 21 were pediatric patients (28%) and 53 were adults (72%). Surgical reconstruction procedures included 43 partial ossicular reconstructions (POR) and 31 total ossicular reconstructions (TOR). The postoperative ABG improved significantly compared to preoperative measurements, and the mean ABG closure was 7.85 dB HL (p = 0.00064). No statistically significant differences in audiological outcomes between TOR/POR techniques and pediatric/adult groups were found in our study cohort, with p values of 0.10 and 0.88, respectively. CONCLUSIONS: At present, EEO can be considered a valid surgical option for re-establishing a functioning ossicular chain with acceptable hearing restoration in children and adults. Further reports in wider case series are required to confirm these results.
