Recurrent colonic cancer developing at the site of a stapled stump: Report of a case

We report herein the case of a 54-year-old woman who developed a recurrence of carcinoma in a stapled colon stump 2 years after undergoing an anterior resection for carcinoma of the rectosigmoid colon. At this time an end to end anastomosis (EEA) stapler had been used to perform a side-to-end anastomosis. The implantation of cancer cells was thought to have caused the recurrence.     

The role of transanal drainage tube in preventing the anastomotic leakage in rectal cancer surgery without a defunctioning stoma: A meta-analysis

BackgroundAnastomotic leakage is a common and serious complication after rectal cancer surgery. The role of transanal drainage tube (TDT) in the prevention of anastomotic leakage is still controversial. The aim of this study was to evaluate the role of TDT in preventing anastomotic leakage.MethodsTwo reviewers individually searched the PubMed, Embase and Cochrane Library ranging from January 2000 to June 2022. The pooled odds ratio (ORs) and weighted mean difference (WMD) with the 95% confidence interval (95% CI) were used to assess anastomotic leakage and other parameters.ResultsA total of 3383 patients (1508 in the TDT group and 1875 in the cohort study group) were included in 13 studies. The study found that patients treated with TDT had a lower incidence of anastomotic leakage with or without neoadjuvant radiotherapy. Moreover, patients who received TDT had lower rates of reoperation and tended to reduce the severity of anastomotic leakage.ConclusionsFor rectal cancer patients without defunctioning stoma, TDT could reduce the incidence of anastomotic leakage, decrease the reoperation rate of patients, and tend to reduce the severity of anastomotic leakage. More RCT are needed to assess the role of TDT in rectal cancer surgery.     

Anal metastasis from carcinoma of the lung: Report of a case

We report herein the case of a 75-year-old man who developed anal canal metastasis from squamous cell carcinoma of the lung. Initially, he underwent a right middle and lower lobectomy combined with left atrial wall resection under cardiopulmonary bypass. He presented 3 months later with an anal polyp which had prolapsed and bled, for which he underwent a transanal polypectomy. Histologically, the polyp was classified as squamous cell carcinoma and considered to be a metastasis from the primary lung cancer. He is presently well with no signs of recurrence 9 months after his initial operation. To our knowledge, there has been no other case of anal metastasis from lung cancer ever reported.     

Development of synchronous bilateral lung cancers after esophagectomy for esophageal cancer: Report of a case

It is well known that squamous cell carcinoma of the esophagus can be associated with carcinoma of other organs. We report herein the rare case of a 60-year-old man who developed sychronous bilateral lung cancers after undergoing esophagectomy for esophageal cancer. Staged bilateral lobectomy was successfully performed to minimize respiratory complications 3 years after his esophagectomy. This case report serves to demonstrate that aggressive and careful surgical approach with adquate followup offers the chance of long-term survival for patients with multiple primary cancers.     

Chest wall implantation of lung cancer after thin-needle aspiration biopsy

Percutaneous aspirational biopsy of intrathoracic lesions has become a popular technique. One of the rarest complications is that of implantation of malignant cells within the needle tract and subsequent development of a chest wall mass. A case of chest wall implantation of adenocarcinoma of the lung after thin-needle biopsy is reported. The lesion was successfully treated with radical full-thickness excision of the chest wall and immediate reconstruction with a large rectus abdominis musculocutaneous flap.     

Laparoscopic adrenalectomy for solitary metachronous adrenal metastasis from lung cancer: Report of a case

We report herein the case of a 69-year-old man who underwent laparoscopic adrenalectomy for a solitary adrenal metastasis 10 months after a left lower lobectomy for T2N1M0 lung cancer. A 30×20 mm tumor was found in the left adrenal gland, and dissected using an ultrasonically activated scalpel. Histological examination revealed metastatic squamous cell carcinoma. The patient recovered uneventfully and his condition is now stable 18 months after the second operation, with no evidence of local recurrence or metastatic disease. Although laparoscopic resection for malignant adrenal tumors is still controversial, we consider that laparoscopic adrenalectomy may be an optional treatment for metastatic adrenal tumors, provided the tumor is solitary, small in size, and well-localized. To our knowledge, only 14 cases of laparoscopic adrenalectomy for malignant tumors have been reported to date; however, this is the first case of successful laparoscopic adrenalectomy for a metastasis from lung cancer.     

Duodenal metastasis from large cell carcinoma of the lung: Report of a case

Duodenal metastasis from primary lung cancer is extremely rare. It rarely shows any symptoms, and the prognosis for this condition is poor. We herein describe the case of a 46-year-old woman with primary lung cancer who underwent a left upper lobectomy. Severe anemia was observed about 20 days after lobectomy. Gastroduodenoscopy showed duodenal metastasis. Simultaneously, brain metastasis was also detected using magnetic resonance imaging. The patient underwent a local resection of the duodenum and a tumor resection of the brain. Postoperative irradiation of the brain metastases and systemic chemotherapy of the lung metastases were performed, and complete remission occurred. However, abdominal lymph node metastasis recurred, and the patient died 1 year after the lobectomy.     

Chest wall invasive non-small cell lung cancer: Patterns of failure and implications for a revised staging system

Background: To assess outcomes and patterns of failure for chest wall invasive non-small cell lung cancer (T₃ or IIIA NSCLC), data were acquired prospectively on 47 consecutive patients at a single institution over 6 years. Methods: Preresectional stagings included bone scan, head and chest/abdominal computed tomography, and mediastinoscopy. There were 25 superior sulcus tumors (radiation and/or chemotherapy followed by resection) and 22 other chest wall invasive NSCLCs (resection alone). Results: There were no perioperative deaths. Seventeen patients (36%) had an operative complication (median length of stay increased from 7 to 12 days; p<0.05). A complete pathologic resection was achieved for 44 of 47 patients (94%). The median survival was 38 months (actuarial 2- and 5-year survival rates of 62% and 50%, respectively). Median lengths of survival for superior sulcus and other chest wall tumors were 36 and >60 months, respectively. Significant univariate predictors of decreased overall and cancer-free survival were poor performance status, positive margins, and positive lymph nodes. Recurrence was observed in 22 of 47 patients (46%) at a median of 8 months (range 2–24); patterns of failure were in the ipsilateral chest (n=2; 4%) and at a distant site (n=15; 32%) or both (n=5; 11%). Conclusions: The operative risk for chest wall invasive NSCLC is acceptable, even after neoadjuvant therapy, allowing for a 94% complete resection rate. The survival of this subset of stage IIIA patients may warrant a reappraisal of the international staging system.

Abdominal wall recurrence of Hilar bile duct cancer 12 years after a curative resection: Report of a case

A 74-year-old woman was diagnosed with hilar bile duct cancer, and underwent a curative resection of the bile duct and the left and caudate lobes of the liver in 1995. Ten years later (April 2005), she noted a small mass in the abdominal wall. The mass slowly enlarged to reach 4 cm in diameter by January 2007. With a diagnosis of a possible recurrence of bile duct cancer, a laparotomy was thus performed. The abdominal wall tumor was buried in the rectus abdominis muscle and was tightly attached to the ileum. The lesion was resected en bloc with the associated rectus muscle and ileocecal region. A histopathological examination of the resected specimen revealed tubular adenocarcinoma that closely resembled the original primary bile duct cancer. In addition, the immunohistochemical staining pattern of the abdominal tumor was identical to that of the original bile duct cancer. This indicated that the abdominal tumor represented a local recurrence (probably due to peritoneal implantation) at 12 years after the resection of the hilar bile duct cancer. This case emphasizes that long-time surveillance is required for patients with bile duct cancer, even if they have survived without recurrence for more than 5 years after a curative resection.     

Metastatic implantation of an oral squamous-cell carcinoma at a percutaneous endoscopic gastrostomy site

Percutaneous endoscopic gastrostomy (PEG) has become an important adjunct in the care of the head-and-neck cancer patient. When resection will likely affect swallowing, PEG can be performed just prior to cancer resection. However, it is unclear whether PEG should be the procedure of choice for establishing enteral access in head-and-neck cancer patients. In this report we describe a man with advanced oral squamous cell carcinoma who had a One-Step PEG button inserted immediately prior to his cancer resection. Six months later, the patient developed metastatic squamous-cell carcinoma at the PEG site. Although the mechanism of spread cannot be confirmed, direct seeding from passage through the cancer-filled oral cavity seems likely. Methods of establishing enteral access which avoid tumor-contaminated fields, such as use of an overtube during conventional PEG, open gastrostomy, or laparoscopic gastrostomy, may be more appropriate in head-and-neck cancer patients.     

Mediastinal lymph node involvement as the initial manifestation of occult thyroid cancer in the surgical treatment of lung cancer: Report of a case

A 63-year-old man was referred to our institute for the treatment of squamous cell carcinoma of the upper lobe of his right lung. A right upper lobectomy of the lung was performed with a mediastinal lymph node dissection. The postoperative pathological examination of the dissected specimens revealed one of the superior mediastinal lymph nodes to be morbid with micrometastasis of occult thyroid cancer, while no node involvement was seen due to lung cancer. A right lobectomy of the thyroid gland with a modified radical neck dissection was done 4 years later after the confirmation of the absence of any recurrent sign of lung cancer. In the resected specimen, papillary thyroid microcarcinoma was observed with several intraglandular metastases and right regional lymph node involvement. Eight months later, a new primary lung cancer developed in the left lung, and a left upper lobectomy of the lung with a mediastinal lymph node dissection was performed. At that time, the absence of mediastinal lymph node metastasis from lung cancer or thyroid cancer was confirmed. Mediastinal lymph node involvement as the initial manifestation of occult thyroid cancer in surgical treatment for lung cancer is rare, but it is important to be aware of the possibility of incidentally detecting occult thyroid cancer in surgical dissections in this area for lung cancer. The appropriate surgical treatment should be determined while carefully considering the prognosis of the lung cancer as well as that of any coexisting malignancy.     

胸腔镜食管癌根治术后胸腔单一负压引流管与常规引流管临床效果比较

目的评估胸腔镜食管癌根治术后应用单一负压引流管的有效性和安全性。 方法选取2014年1月—2017年1月海军军医大学第二附属医院胸外微创中心收治的83例食管癌患者,根据术中采用引流管的不同,分为负压引流管组(n＝40)和28F号常规引流管组(n＝43)。比较两组患者术后胸腔积气、积液、皮下气肿、胸引液总量、引流管持续时间、术后住院日、术后引流管拆线时间、切口愈合率、引流管相关并发症、切口VAS疼痛评分等指标。 结果两组患者的基线资料和术后胸腔积液、胸腔积气、皮下气肿发生率,以及切口愈合不良率、平均住院时间、引流管持续时间及引流管相关并发症发生率比较,差异均无统计学意义(P>0.05)。与常规引流管组比较,负压引流管组患者的术后胸腔引流量明显减少,瘢痕反应率明显降低,拆线时间明显缩短,VAS疼痛评分明显降低,差异均有统计学意义(P<0.05)。 结论胸腔镜食管癌根治术后应用单一负压引流管安全、有效,与常规28F胸引流管临床效果相当,且有助于患者术后快速康复。     

Endoscopic decompression using a transanal drainage tube for acute obstruction of the rectum and left colon as a bridge to curative surgery

Objective  The aim of this study was to clarify the usefulness of the management of acute left colon and rectum obstruction because of colorectal carcinoma using a transanal ileus drainage tube before curative surgery.
Method  Forty-six patients (24 males and 22 females, aged 24–94 years, mean = 56.2) treated between September 2005 and March 2007 for acute left colon and rectal obstruction were identified in a colorectal obstruction database, and their clinical and radiological features were reviewed. After a cleaning enema was administered, urgent colonoscopy was performed. Subsequently, endoscopic decompression using a ileus tube was attempted.
Results  Endoscopic decompression using the ileus tube was technically successful in 45 of 46 patients (97.8%). Perforation occurred in one patient 3 days later and emergent operation was performed. The site of obstruction was the rectum in 15 patients, the sigmoid colon in 18, the descending colon in 13. Following adequate cleansing of the colon, patients' abdominal girth were decreased from 91 ± 4 cm before drainage to 82 ± 2 cm 7 days later, and one-stage surgery after 8 ± 1 days (SD; range 7–10 days) were performed. No anastomotic leakage or postoperative stenosis occurred after operation.
Conclusion  Management of acute left colon and rectum obstruction because of colorectal carcinoma using the ileus tube was found to be effective and safe, considered as a bridged method before curative surgery.

目的 比较腹腔镜胆总管探查放置自行脱落J管一期缝合与T管引流的临床疗效,探讨胆总管一期缝合放置自行脱落J管引流的可行性。方法 回顾性分析2019年3月至2020年10月西安交通大学附属咸阳市中心医院肝胆外科156例行腹腔镜下胆囊切除联合胆总管探查患者的临床资料。按手术方式分为自行脱落J管组（n=80）和T管引流组（n=76）,比较两组患者基线资料、术中术后情况及并发症等。结果 两组手术总时间、术中出血量、术后并发症情况无统计学差异（P＞0.05）。自行脱落J管组较T管引流组术后下床活动时间[（18.2±7.2）h vs（22.1±8.3）h,t=3.139,P=0.002]、术后排气时间[（1.7±0.9）d vs（2.1±1.3）d,t=2.244,P=0.026]、补液总量[（5 634.1±432.8）mL vs（6 351.4±547.9）mL,t=13.56,P＜0.001]、拔管时间[（8.7±3.3）d vs（47.1±13.0）d,t=14.966,P＜0.001]、住院时间[（7.9±2.8）d vs（9.4±3.3）d,t=3.067,P=0.003]、住院总费用[（15 489.2±2 217.1）元 vs（18 136.4±2 251.3）元,t=7.398,P＜0.001]差异有统计学意义。结论 严格掌握手术适应证前提下,自行脱落J管引流扩大了胆总管一期缝合适应证,安全有效,相比T管引流具有加速康复、减少住院费用、缩短住院时间等优势。     

Endoscopic decompression of benign large bowel obstruction using a transanal drainage tube

Aim Endoscopic decompression of malignant colorectal obstruction is often dealt with using expandable metallic stents. Endoscopic decompression of benign large bowel obstruction is more difficult. We report the technique and outcome of transanal endoscopic decompression for benign large bowel obstruction. Method From January 2001 to June 2010, endoscopic decompression using a transanal drainage tube placement was attempted in consecutive patients with benign large bowel obstruction. The clinical features, technical success, complications, treatment after the tube placement and clinical success were retrospectively evaluated. Results There were 13 patients (seven males, age 47–87, mean 69 years). The sites of obstruction were transverse colon [5 (38%)], sigmoid colon [3 (23%)], ileocecal valve [2 (15%)], splenic flexure [1 (8%)], descending colon [1 (8%)] and rectum [1 (8%)]. The most common cause of obstruction was anastomotic stricture [9 (69%)]. In 12 (92%) patients transanal decompression was technically successful with one perforation. An overtube, the reinsertion of colonoscope along the decompression tube, or the use of a small‐diameter endoscope was required for the tube placement in seven (54%). In seven (54%) patients tube placement alone resulted in relief of bowel obstruction without operation. Conclusion Endoscopic decompression using a transanal drainage tube is effective for the management of benign large bowel obstruction.     

Chest wall metastasis of endometrial cancer: case report and review of the literature

Introduction: Endometrial cancer is the fourth most common female cancer and also distant metastases to the chest wall associated with these tumors are seen less common. Surgical treatment options for metastases of endometrial cancer are limited.

Case: A 57-year-old patient who underwent total abdominal hysterectomy?+?bilateral salpingo oophorectomy and received adjuvant chemotherapy for endometrioid-type adenocarcinoma of the endometrium and tuba is presented. The patient initially presented with pleural effusion 8 years ago and the tumor was detected while during etiologic screening. The patient had no problems after adjuvant chemotherapy and had been living in another city when she presented with a mass on the chest wall measuring 20?×?15?×?12?cm 8 years after the initial diagnosis and distant organ metastasis due to the first surgery was detected. The mass was first thought to be a sarcoma and the tru-cut biopsy revealed a metastatic lesion that was immunohistochemically similar to the first surgical specimen. The mass was resected with a wide radical excision and ‘no touch’ technique. The patient was then discharged with no postoperative complications.

Conclusion: Here in, a case with a distant organ metastasis due to an endometrioid-type adenocarcinoma is presented accompanied by literature data.
