Evaluation of Ischemic Time and Complications in Free Jejunum Transfer.

In free jejunum transfer, knowing the ischemic tolerance time of the jejunum is crucial. It helps determine the need for reharvesting if an unexpected situation prolongs the ischemic time. The current ischemic tolerance time in humans is unknown. We investigated the relationship between ischemic time and postoperative complications in head and neck cancer patients who underwent free jejunum transfer. The study included 76 patients with available medical records out of 103 patients who underwent free jejunum transfer between 2009 and 2023. The association between the surgical procedure, including ischemic time, and patient's background, and flap engraftment, stenosis of the intestinal anastomosis, the swallowing function, and other complications was investigated. The ischemic time for jejunal flaps ranged from 1 h 24 min to 6 h, with a mean of 197 ± 55.5 min. In 72 patients, the jejunum was successfully engrafted, but vascular occlusion occurred in another four patients. In three of these patients, jejunal necrosis occurred, and there was no specific trend in ischemic time. Stenosis of the intestinal anastomosis occurred in 17 cases (22%), with ischemic time (≥3 h) and age (≥75 years) being significant factors for stenosis (ischemic time: 30% vs. 10%, p = 0.048, age: 50% vs. 15%, p < 0.01). No significant correlations were observed with other complications or the swallowing function. There was no specific trend between ischemic time and jejunal survival rate, indicating that an ischemic time within 6 h may not have affected engraftment. Although we have recently performed intestinal anastomosis prior to vascular anastomosis, the choice of surgical technique should be adapted to the patient's age and background.

The Ischemic Tolerance up to Four Hours of Free Jejunum Flap: A Retrospective Cohort Study.

While free jejunum transfer (FJT) following total pharyngo-laryngo-esophagectomy (TPLE) is a reliable reconstruction technique, the jejunum flap is viewed as more susceptible to ischemia than a standard free flap. Animal studies have indicated that the jejunum can tolerate ischemia for as little as 2 to 3 hours. Clinical studies also reported increased complications after the FJT with more than 3 hours of ischemia. Traditionally, our institution has carried out FJT with an initial intestinal anastomosis, followed by a vascular anastomosis, which often results in extended jejunal ischemia time. In this study, we retrospectively examined the actual tolerance of the jejunum to ischemia, considering perioperative complications and postoperative dysphagia. We retrospectively studied 402 consecutive cases involving TPLE + FJT. Patients were divided into five groups based on jejunum ischemia time (∼119 minutes, 120∼149 minutes, 150∼179 minutes, 180∼209 minutes, 210 minutes∼), with each variable and result item compared between the groups. Univariate and multivariate analyses were conducted to identify independent factors influencing the four results: three perioperative complications (pedicle thrombosis, anastomotic leak, surgical site infection) and dysphagia at 6 months postoperatively. The mean jejunal ischemia time was 164.6 ± 28.4 (90-259) minutes. When comparing groups divided by jejunal ischemia time, we found no significant differences in overall outcomes or complications. Our multivariate analyses indicated that jejunal ischemia time did not impact the three perioperative complications and postoperative dysphagia. In TPLE + FJT, a jejunal ischemia time of up to 4 hours had no effect on perioperative complications or postoperative dysphagia. The TPLE + FJT technique, involving a jejunal anastomosis first followed by vascular anastomosis, benefits from an easier jejunal anastomosis but suffers from a longer jejunal ischemia time. However, we found that ischemia time does not pose significant problems, although we have not evaluated the effects of jejunal ischemia extending beyond 4 hours.

Cannulation Indocyanine Green Method for Strategic Management of Postoperative Arterial Thrombosis after Free Jejunal Flap Transfer

Summary: Indocyanine green (ICG) angiography is widely used in reconstructive surgery to confirm the perfusion of the flap. Here, we report a case in which the use of the “cannulation ICG method” was useful for strategic management of postoperative arterial thrombosis after free jejunal flap transfer. A 64-year-old woman underwent cervical esophagectomy followed by a free jejunal transfer. On postoperative day 3, ischemia of the free jejunum was suspected, and takeback was performed. In the reoperation, re-anastomosis of the artery was planned after the removal of arterial thrombus. However, before re-anastomosis, it was unclear whether there was venous thrombus and whether this jejunum flap was salvageable. To resolve these two questions, we performed the cannulation ICG method. In this method, we injected a mixture of 1.0 mL of ICG and 20 mL of blood into the jejunal artery via 24-gauge cannula. We then evaluated the perfusion of the jejunal flap and monitoring jejunum, and the patency of the venous anastomosis site using a near-infrared fluorescence imaging device (LIGHTVISION; Shimadzu Corporation, Kyoto, Japan). In this case, the whole jejunal flap (including the monitoring jejunum) and venous anastomosis site were highlighted. We determined that there were no venous thrombi and that the entire jejunum was salvageable. After the arterial re-anastomosis, ICG angiography showed good perfusion of the whole jejunum. The postoperative course was uneventful, and the free jejunal flap survived completely. The cannulation ICG method may be effective for determining the surgical method for reoperation due to arterial thrombosis after reconstruction of the free jejunum.

Second free jejunum transfer after flap loss does not affect oral intake: A retrospective case-control study

Free jejunum transfer is one of the standard procedures for restoring oral intake after total pharyngo-laryngo-esophagectomy. Flap loss leading to a second free jejunum transfer rarely occurs. This study investigated the impact of a second free jejunum transfer on post-operative oral intake. A retrospective review was conducted on patients who underwent a first free jejunum transfer between July 1998 and December 2019. A total of 367 patients were included in the study. Among them, 17 patients who underwent a second free jejunum transfer because necrosis constituted the second free jejunum transfer group, whereas 350 patients who did not require a second free jejunum transfer formed the first free jejunum transfer group. The incidence of dysphagia requiring tube feeding and post-operative complications was compared between the two groups. Moreover, risk factors for dysphagia and complications were estimated. There were no statistically significant differences in the incidence of dysphagia post-operation between the two groups. A second free jejunum transfer was a statistically significant factor for complications at 2- and 6-months post-operation; however, there were no significant differences in complication rates at the 12-month follow-up. Furthermore, there were no significant differences in the incidence of severe complications between the two groups. Although a second free jejunum transfer increases early complications, it is not associated with major complications and does not negatively impact oral intake. These findings support the conclusion that free jejunum transfer is safe and helps maintain post-operative quality of life.

Free jejunum transfers in oncologic reconstruction

Methods of pharyngoesophageal reconstruction include gastric pull-up, colon or jejunal interposition, and transfer of a free anterolateral thigh flap. The most popular method at our institution is transfer of a free jejunal graft. The free jejunum transfer was first described in 1957 by Seidenberg. The advantage of this procedure is a decreased risk of fistula, because the pharyngoesophagus is physiologically reconstructed with bowel-type reconstruction material. There are few reports about the operative methods of free jejunum transfer in detail and the operative methods vary greatly by institution. We performed free jejunum transfers for several hundred patients in the past and reported the characteristics and intraoperative and postoperative matters that require attention. Here, we summarize free jejunum transfer in oncologic reconstruction with relation to the points of safety, recipient vessels and microsurgical anastomosis, intestinal anastomosis and postoperative complications based on our experience and published reports.

Efficacy of surgical comprehensive therapy for 456 cases of hypopharyngeal carcinoma

Objective: To retrospectively analyse the efficacy of surgerical comprehensive treatment for hypopharyngeal cancer. Methods: Four hundred and fifty-six cases of hypopharyngeal squamous cell carcinoma treated from Jan 2014 to Dec 2019 were analyzed retrospectively, including 432 males and 24 females, aged 37-82 years old. There were 328 cases of pyriform sinus carcinoma, 88 cases of posterior pharyngeal wall carcinoma, and 40 cases of postcricoid carcinoma. According to American Joint Committe on Cancer(AJCC) 2018 criteria, 420 cases were of stage Ⅲ or Ⅳ; 325 cases were of T3 or T4 stage. Treatment methods included surgery alone in 84 cases, preoperative planned radiotherapy plus surgery in 49 cases, surgery plus adjuvant radiotherapy or concurrent chemoradiotherapy in 314 cases, and inductive chemotherapy plus surgery and adjuvant radiotherapy in 9 cases. The primary tumor resection methods included transoral laser surgery in 5 cases, partial laryngopharyngectomy in 74 cases, of them 48 cases (64.9%) presented with supracricoid hemilaryngopharyngectomy, total laryngectomy with patial pharyngectomy in 90 cases, total laryngopharyngectomy or with cervical esophagectomy in 226 cases, and total laryngopharyngectomy with total esophagectomy in 61 cases. Among 456 cases, 226 cases received reconstruction surgery with free jejunum transplantation, 61 cases with gastric pull-up, and 32 cases with pectoralis myocutaneous flaps. All patients underwent retropharyngeal lymph node dissection, and high-definition gastroscopy was performed during admission and follow-up. SPSS 24.0 software was used to analyze the data. Results: The 3-year and 5-year overall survival rates were respectively 59.8%, and 49.5%. The 3-year and 5-year disease specific survival rates were respectively 69.0% and 58.8%. Total metastasis rate of retropharyngeal lymph nodes was 12.7%. A total of 132 patients (28.9%) suffered from simultaneous and metachronous multiple primary carcinoma of the hypopharynx. Multivariate Logistic regression analysis showed that T3-4 disease, cervical lymph node metastasis, retropharyngeal lymph node metastasis and postoperative adjuvant radiotherapy were independent factors affecting the prognosis of patients (all P<0.05). As of April 30, 2022, a total of 221 patients died during follow-up, of 109 (49.3%) with distant metastases, which were the main cause of death. Conclusions: The efficacy of comprehensive treatment for hypopharyngeal cancer can be improved by accurate preoperative evaluation, improved surgical resection, active retropharyngeal lymph node dissection and full process intervention of the second primary cancer.

Transverse Cervical Artery for Head and Neck Reconstruction with Free Jejunal Flaps: A Retrospective Study of Computed Tomography Angiography.

The transverse cervical artery is less commonly used than other external carotid arteries as a recipient vessel. Therefore, we aimed to compare the utility of the transverse cervical artery as a recipient vessel with that of the external carotid artery system for microvascular head and neck reconstruction by quantitative analysis of dynamic-enhanced computed tomography. Fifty-one consecutive patients who underwent free jejunum transfer following total pharyngolaryngectomy between January 2017 and December 2020 were retrospectively reviewed. Ninety-four pairs of the diameters of the transverse cervical artery, superior thyroid artery, and lingual artery, measured via computed tomography angiography, were analyzed. Operative outcomes were compared between the following groups based on the recipient artery: transverse cervical artery (n = 27), superior thyroid artery (n = 17), and other artery (n = 7) groups. In the analysis of the computed tomography angiography, nine transverse cervical arteries (9.6%) could not be identified. However, the percentage was significantly lower than the percentage of superior thyroid arteries (20.2%) and lingual arteries (18.1%) (p < 0.01). Among the identified vessels, the transverse cervical arteries (2.09 ± 0.41 mm) and the lingual arteries (1.97 ± 0.40 mm) were significantly larger than the superior thyroid arteries (1.70 ± 0.36 mm) in diameter at the commonly used level (p < 0.01). Multivariate analysis revealed that prior radiation therapy was not an independent factor significantly affecting transverse cervical artery diameter (p = 0.17). Intraoperative anastomotic revision was required in only two cases of the superior thyroid artery. The transverse cervical artery can offer a larger caliber and more reliable candidate than the superior thyroid artery for a recipient artery. More liberal use of the transverse cervical artery may improve the safety of microsurgical head and neck reconstruction.

Preservation of remnant esophagus during total pharyngolaryngectomy in a patient with previous subtotal esophagectomy: a case report

BackgroundWith the improved survival rate of patients with esophageal cancer, secondary cancers, including pharyngolaryngeal cancer, have become a problem. Phanryngolaryngeal cancer surgery often requires esophagogastric anastomosis resection in patients with a previous history of subtotal esophagectomy. Owing to adhesions, especially surrounding the esophagogastric anastomosis, caused by the initial surgery, the second surgery might cause postoperative complications.Case presentationA 65-year-old man was diagnosed with early stage esophageal squamous cell carcinoma and underwent endoscopic mucosal dissection. However, the histopathological depth of the tumor was pT1b, and additional treatment was required. After administration of the neoadjuvant chemotherapy, he underwent thoracoscopic esophagectomy and retrosternum reconstruction via a gastric tube (pT1N3M0 stage III). Eight months after the first surgery, tumor recurrences were observed at the anastomosis and left cervical lymph node. Definitive chemoradiotherapy was performed for the recurrences, and complete response was achieved. Seven months after chemoradiotherapy, he was diagnosed with hypopharyngeal squamous cell carcinoma in the right piriform fossa (cT2N2bM0 stage IVA), and salvage surgery was chosen as treatment. The surgical findings revealed strong adhesion around the remnant esophagus, which was difficult to dissect from surrounding tissue and was associated with a risk of breaking of the anastomosis. However, indocyanine green fluorescence imaging findings indicated sufficient blood flow to preserve the remnant esophagus, including the anastomosis, even after the interruption of blood flow from the proximal side of the esophagus by total pharyngolaryngectomy. Finally, approximately 4 cm of the remnant esophagus was preserved, and the free jejunum reconstruction with cervical vascular anastomosis was performed. Moreover, the patient was discharged without complications on postoperative day 38. After 10 months of the second surgery, a metastatic lymph node was observed in the right neck. Immune checkpoint inhibitors and chemotherapy were administered, and the patient is alive and under treatment 1.5 years after the second surgery.ConclusionsBlood supply to the remnant cervical esophagus was thought to be from the gastric conduit over the anastomosis and surrounding capillaries. Thus, the preservation of the remnant esophagus can be considered in total pharyngolaryngectomy even after < 2 years of esophagectomy by blood flow evaluation using indocyanine green fluorescence.

Surgical outcomes of reconstruction using the gastric tube and free jejunum for cervical esophageal cancer: analysis using the National Clinical Database of Japan.

Cervical esophageal cancer accounts for a small proportion of all esophageal cancers. Therefore, studies examining this cancer include a small patient cohort. Most patients with cervical esophageal cancer undergo reconstruction using a gastric tube or free jejunum after esophagectomy. We examined the current status of postoperative morbidity and mortality of cervical esophageal cancer based on big data. Based on the Japan National Clinical Database, 807 surgically treated patients with cervical esophageal cancer were enrolled between January 1, 2016, and December 31, 2019. Surgical outcomes were retrospectively reviewed for each reconstructed organ using gastric tubes and free jejunum. The incidence of postoperative complications related to reconstructed organs was higher in the gastric tube reconstruction (17.9%) than in the free jejunum (6.7%) for anastomotic leakage (p < 0.01), but not significantly different for reconstructed organ necrosis (0.4% and 0.3%, respectively). The incidence rates of overall morbidity, pneumonia, 30-day reoperation, tracheal necrosis, and 30-day mortality using these reconstruction methods were 64.7% and 59.7%, 16.7% and 11.1%, 9.3% and 11.4%, 2.2% and 1.6%, and 1.2% and 0.0%, respectively. Only pneumonia was more common in the gastric tube reconstruction group (p = 0.03), but was not significantly different for any other complication. The incidence of overall morbidities and reoperation, especially anastomotic leakage after gastric tube reconstruction, suggested a necessity for further improvement. However, the incidence of fatal complications, such as tracheal necrosis or reconstructed organ necrosis, was low for both reconstruction methods, and the mortality rate was acceptable as a means of radical treatment.

A case of long-term survival treated with three metastasectomies and two subsequent adjuvant nivolumab therapies for recurrent malignant melanoma of the esophagus

BackgroundThe treatment strategy for metastatic lesions of primary malignant melanoma of the esophagus (PMME) is currently determined on a case-by-case basis, based on the National Comprehensive Cancer Network (NCCN) guidelines for cutaneous melanoma. The NCCN guidelines state that resection should be considered in patients with resectable metastatic recurrence. Herein, we report a case of long-term survival treated with three metastasectomies and two subsequent adjuvant nivolumab therapies for the metastatic recurrence of PMME.Case presentationA 65-year-old female patient with PMME underwent thoracoscopic subtotal esophagectomy, gastric tube reconstruction via the posterior mediastinal route, and cervical esophagogastric anastomosis. Histopathological examination of the resected specimen revealed that the tumor was PMME with tumor invasion into the muscularis propria and no lymph node metastasis. At the age of 68 years, she developed intestinal invagination due to jejunal metastasis of malignant melanoma and underwent resection of the jejunum. Histopathological examination of the resected specimen revealed two metastases of malignant melanoma in the jejunum and one metastasis to the mesenteric lymph node. At the age of 75 years, a recurrence of malignant melanoma was found in the cervical esophagus. She underwent thoracoscopic mobilization of the gastric tube and esophagus followed by cervical esophagectomy and reconstruction with a free jejunum flap. She received 24 courses of nivolumab therapy for 1 year as a postoperative adjuvant therapy. Subsequently, at the age of 78 years, an enlarged left cervical lymph node and a mass in the right lower lobe of the lung were found. She underwent left cervical lymph node dissection and thoracoscopic wedge resection of the right lung. Histopathological examination of the resected specimens revealed that both tumors were metastases of malignant melanoma. At age 79 years, she received eight courses of nivolumab therapy as a second postoperative adjuvant therapy, with no sign of recurrence in a 9-month follow-up period after the third metastasectomy.ConclusionIn cases of metastatic recurrence of PMME, aggressive resection of oligometastasis with postoperative adjuvant nivolumab therapy may result in long-term survival.

Posterior ischemic optic neuropathy following postoperative bleeding and internal jugular vein compression.

Perioperative blindness, especially posterior ischemic optic neuropathy (PION), is an uncommon but potentially devastating complication. We report a case of a 65-year-old male patient who underwent laryngopharyngectomy, bilateral neck dissection, and free jejunum flap reconstruction, but then experienced PION in his right eye following postoperative bleeding and bilateral internal jugular veins (IJVs) compression. Despite systemic corticosteroid therapy, his visual recovery prognosis was poor. The specific mechanism responsible for PION remains unclear, and no therapy has been shown to improve this condition. As such, prevention of perioperative PION remains the only available strategy. Surgeons should be aware of this rare potential complication and its risk factors and strive to avoid it. As postoperative bleeding and IJV compression are one of important risk factors for PION, avoiding these are critical.

A modified tracheal transection approach for cervical esophageal lesion treatment: A report of 13 cases.

Surgical interventions for tumors in the cervical esophageal region are complicated and laryngeal function is frequently sacrificed. Therefore, we attempted the tracheal transection approach to resect the tumor while preserving laryngeal function. Three patients with papillary thyroid cancer (PTC), six with cervical esophageal cancer (CEC), and four with CEC mixed with thoracic esophageal cancer (TEC) were enrolled. The esophagus was exposed after the trachea was transected between the second and third tracheal rings. CEC/TEC: Resection of the esophagus or/and a portion of the hypopharynx with acceptable safety margins and repair with free jejunum or tubular stomach. PTC: Suture the small esophageal incision immediately after removing the tumor. The tracheal dissection was repaired with interrupted sutures throughout the entire layer after the esophageal lesion was resected. The status of the recurrent laryngeal nerve (RLN) determined whether a tracheotomy was necessary. All 13 patients had effective esophageal lesion excision, with six of them requiring intraoperative tracheotomy. Postoperative complications included a tracheoesophageal fistula (one case, 7.7%), postoperative RLN paralysis (two cases, 15.4%), and aspiration (three cases, 23.1%). Except for two patients with distant metastases, there was no recurrence in the remaining patients after 5-92 months of follow-up. The tracheal transection approach, as a new surgical technique, can retain laryngeal function while ensuring appropriate exposure and satisfactory surgical resection. Before surgery, the feasibility of this approach must be carefully assessed. The RLN should be protected during the procedure. The operation is both safe and effective, with a wide range of applications.

255. CURRENT STATUS IN POSTOPERATIVE SHORT-TERM OUTCOMES OF ESOPHAGEAL RECONSTRUCTION USING THE GASTRIC TUBE AND FREE JEJUNUM FOR CERVICAL ESOPHAGEAL CANCER

Abstract Cervical esophageal cancer is rare of esophageal cancers. Therefore, there is currently no survey for a large cohort of postoperative short-term outcomes. The gastric tube or the free jejunum are the two major reconstructed organs in esophageal reconstruction after esophagectomy for cervical esophageal cancer. This study aimed to clarify the current status of esophageal reconstruction by reconstructed organ after esophagectomy for cervical esophageal cancer, especially postoperative morbidities and mortality. Based on the Japan National Clinical Database, 807 surgically treated cases of cervical esophageal cancer between January 1, 2016, and December 31, 2019, were enrolled. Clinical outcomes were compared between the gastric tube group and the free jejunum group. The frequency of surgical site infection in organ space, anastomotic leakage, pneumonia, empyema, and chylothorax was significantly higher in the gastric tube group (10.0%, 17.9%, 16.7%, 2.0%, and 3.3%, respectively) than in the free jejunum group (2.9%, 6.7%, 11.1%, 0.0%, and 0.3%, respectively) (p = &amp;lt;0.001, &amp;lt;0.001, 0.029, 0.008 and 0.005, respectively). Significantly more patients in the gastric tube group required long-term hospitalization over 90 days (p = 0.039). Although these two major reconstructed organs are often not oncologically selectable, our results suggested that the free jejunum reconstruction after esophagectomy for cervical esophageal cancer may be more desirable when confined resection of the cervical esophagus was oncologically acceptable.

Role of jejunoplasty in complex esophageal reconstruction

IntroductionEsophageal reconstruction is a very complex surgical procedure, burdened by significant morbidity. Gastroplasty and coloplasty have classically been used. Free jejunal plasty has shown to be a very good option in the treatment of cervical esophagus pathology, but the role of supercharged jejunoplasty in thoracic esophagus reconstruction is still controversial. MethodsA retrospective study of esophageal reconstructions with jejunoplasties performed in our unit between January 2011 and December 2019. Epidemiological data, indications, surgical technique, and morbidity and mortality were analyzed. Results67 procedures of esophageal reconstruction were performed, 10 of which were jejunoplasties: 5 free jejunums and 5 supercharged. Morbidity, mortality, mean stay and withdrawal time from enteral feeding were lower in free than in supercharged jejunums. ConclusionsSupercharged jejunoplasty was the last option for reconstruction of the thoracic esophagus. Median sternotomy access provides an excellent approach to the anterior mediastinum and the internal mammary vessels. The free jejunum would be the first choice, with the indemnity of the rest of the esophagus, in the reconstruction of the cervical esophagus.

Efficacy of free anterolateral thigh flap and free jejunum in reconstruction for hypopharyngeal and cervical esophagus.

Because of its peculiar anatomical location, most patients with hypopharyngeal and cervical esophageal cancer are at advanced stage when they visit the hospital. At present, the treatment for hypopharyngeal and cervical esophageal cancer is primarily surgical resection and radiotherapy. However, due to the wide range of surgical resection, it can often lead to a large range of annular defects. Therefore, the upper digestive tract reconstruction after tumor resection is very important. We use the free anterolateral thigh flap (ALT) and free jejunum (FJ) transfer to reconstruct the hypopharyngeal and cervical esophagus, and to investigate the effect of both reconstruction methods on upper gastrointestinal tract defects. A retrospective analysis was conducted to investigate the clinical data of 42 patients with hypopharyngeal and cervical esophageal cancer (Clinical Stage IV) from Jan. 2004 to Jan. 2016 in the Second Xiangya Hospital of Central South University. All patients underwent total laryngopharyngectomy and cervical esophageal resection. The hypopharyngeal circumferential and cervical esophageal defects were reconstructed with free ALT (n=22) or FJ (n=20). Four patients who underwent radiotherapy and chemotherapy before surgery did not receive radiotherapy or chemotherapy after surgery. The remaining 38 patients underwent postoperative radiotherapy and chemotherapy. All patients were followed up by telephone or outpatient review, with a follow-up deadline in Jan. 2021. We compared the differences between the 2 groups in postoperative complications, radiotherapy complications, and survival rate. The differences in individual characteristics between 2 groups were analyzed using Fisher test. The differences in postoperative and radiotherapy complications between two groups were analyzed using χ² test. The 3- and 5-year overall survival rates were calculated using Kaplan-Meier survival curve method. In the ALT group, the postoperative complications mainly included anastomotic fistula, chylous fistula and subcutaneous hematoma of the donor site. The radiotherapy complication was anastomotic stenosis. However, in the FJ group, the postoperative complications mainly included chylous fistula, intestinal obstruction, and intestinal fistula. The radiotherapy complications mainly contained anastomotic fistula and tissue flap necrosis. The cases of postoperative complications in the ALT group and the FJ group were 7 and 5, respectively (P=0.625), and the cases of radiotherapy complications were 3 and 4, respectively (P=0.563). The 3-year overall survival rates in the ALT group and the FJ group were 52.9% and 46.7%, respectively, and the 5-year total survival rates were 35.1% and 31.9%, respectively (P=0.53). The cases of anastomotic stenosis after radiotherapy in the ALT group were more than those in the FJ group (P=0.097). However, the cases of jejunal necrosis and anastomotic fistula after radiotherapy in the FJ group were more than those in the ALT group (P=0.066). There are no significant differences in postoperative and radiotherapy complications and 3-and 5-year survival rates between the ALT group and the FJ group. The reconstruction with ALT is prone to develop anastomotic stricture. The reconstruction with FJ cannot withstand high-dose radiotherapy. The ALT and FJ are effective methods in the reconstruction of hypopharynx and cervical esophagus. The treatment protocol should be carefully chosen based on its advantages and disadvantages of these 2 methods.

A survey of the clinical outcomes of cervical esophageal carcinoma surgery focusing on the presence or absence of laryngectomy using the National Clinical Database in Japan.

One upside of cervical esophageal carcinoma is that radical surgery can be performed by laryngectomy, even for tumors with tracheal invasion. However, this approach drastically reduces the quality of life, such as by losing the vocal function. Cervical esophageal carcinoma is rare, and no comprehensive reports have described the current state of surgery. Using a Japanese nationwide web-based database, we analyzed the surgical outcomes of cervical esophageal carcinoma to evaluate the impact of larynx-preserving surgery. Based on the Japan National Clinical Database, 215 surgically treated cases of cervical esophageal carcinoma between January 1, 2018, and December 31, 2019, were enrolled. Clinical outcomes were compared between the larynx-preserved group and the laryngectomy group. Ninety-four (43.7%) patients underwent larynx-preserving surgery. A total of 177 (82.3%) patients underwent free jejunum reconstruction. More T4b patients and more patients who underwent preoperative radiotherapy were in the laryngectomy group. There were no significant differences in the frequency and the severity of morbidities between the two groups. However, in the laryngectomy group, in-hospital death within 30days after surgery was observed in 1 patient, and the postoperative hospital stay was significantly longer (P = 0.030). In the larynx-preserved group, recurrent nerve paralysis was observed in 24.5%. Re-operation (35.3%, P = 0.016), re-intubation (17.6%, P = 0.019) and tracheal necrosis (17.6%, P = 0.028) were significantly more frequent in patients who underwent pharyngolaryngectomy with total esophagectomy and gastric tube reconstruction than in others. Larynx-preserving surgery was therefore considered to be feasible because it was equivalent to laryngectomy regarding the short-term surgical outcomes.

Hypothyroidism After Using Superior Thyroid Artery as A Recipient Artery.

Superior thyroid artery (SThA) is a common recipient artery in free tissue transfer even after total pharyngolaryngoesophagectomy (TPLE) with hemithyroidectomy. The aim of this study was to evaluate whether the use of SThA as a recipient vessel affect thyroid function in patients undergoing TPLE with hemithyroidectomy. From 2011 to 2020, 91 patients who underwent free jejunum transfer after TPLE with hemithyroidectomy were divided into two groups. In Group1 (n=47), the contralateral SThA was used for the anastomosis. In Group2 (n=44), other vessels were used. Retrospective chart review was performed comparing postoperative thyroid function between two groups. In group1, 17 patients presented hypothyroidism, 21 presented latent hypothyroidism and 9 presented no thyroid dysfunction comparing 15, 19, and 10 respectively in group 2. There were no significant differences between the two groups. Even after hemithyroidectomy, with inferior thyroid arteries are preserved, the SThA can be used as a recipient vessel. 3 Laryngoscope, 133:557-561, 2023.

A survey of feeding and swallowing function after free jejunal flap reconstruction in cases of head and neck cancer.

Reconstructive surgery using the free jejunum flap for locally advanced head and neck cancer is effective in preserving the swallowing function; however, it does not allow normal oral intake in all patients. A total of 47 patients underwent surgery at Nara Medical University between Jan 2010 and Dec 2019. The patients' ages ranged from 48 to 86 years. Sites were the hypopharynx (33 cases), larynx and cervical esophagus (5 cases each) and oropharynx (4 cases). Swallowing function was assessed using videofluorography, from the start of oral intake to discharge, as well as meal form at discharge. Lateral-retropharyngeal-lymph node dissection (LRPLND), preoperative radiation therapy, extended resection to the nasopharynx and incidence of stenosis in the jejuno-esophageal anastomosis were examined. Significant differences were revealed in the scores of pharyngeal residues of contrast medium and pharyngeal contraction, with and without preoperative radiotherapy. LRPLND did not affect swallowing function; dissection group cases had lower scores for soft palate elevation. Overall, resection extended to the nasopharynx, and the anastomosis method did not affect scores of swallowing function.

Soft palate reconstruction with free jejunum flap: Impact on the velopharyngeal insufficiency

If inadequately reconstructed, large resections of the soft palate inevitably cause velopharyngeal insufficiency, nasal regurgitation and reduce speech intelligibility. A series of 12 free Jejunal flaps are presented, with 28.5 months median follow up (IQR 10.5), with evidence that the flaps provided appropriate secretions and good functionality for speech and resumption of oral intake. A retrospective case series was performed, from 2004 to 2020, including patients diagnosed with palate locally advanced squamous cell carcinoma and reconstructed with free jejunum flap. Twelve patients were included, with mean age of 66 years. No flap loss, thrombosis or infection were recorded. Oral feeding was achieved in all patients, on an average after 36 days from the operation. Speech intelligibility improved by 4 points in a scale 0-10. The thin, pliable, and elastic properties of the free jejunal flap are optimally suited for a functional reconstruction of the three-dimensional palatal defects. With its serous and mucous secretion, the free jejunal flap can lead to early return to solid diet and minimize functional impairment of phonation and speech.
