Case report of perineal hernia after laparoscopic abdominoperineal resection

Perineal hernia (PH) is a rare complication following laparoscopic abdominoperineal resection (APR) for rectal cancer. We present a case report of perineal hernia after laparoscopic APR and discuss its management. The patient was a 77‐year‐old man who was diagnosed with lower rectal cancer. He underwent laparoscopic APR and bilateral lateral lymph node dissection. Two months after the surgery, pain and bulging in the perineal region developed, and PH was diagnosed by CT. Repair with a polypropylene mesh was performed using a combination of laparoscopic abdominal and transperineal approaches. Reportedly, the incidence of secondary PH after APR has increased along with the rate of laparoscopic surgery. Treatment of secondary PH with transperineal repair alone may cause injuries to other organs because of adhesion of the pelvic viscera. In the present case, we safely repaired the hernia repair using a laparoscopy‐assisted perineal approach.     

Contrast-enhanced endoscopic ultrasonography (CE-EUS) findings in adrenal metastasis from renal cell carcinoma

Solitary adrenal metastasis is often difficult to distinguish from benign adrenal tumor using only plain computed tomography (CT) scanning. We describe a solitary left adrenal gland mass in a patient who had undergone simultaneous gastrectomy and right nephrectomy for advanced gastric cancer and renal cell carcinoma (RCC), respectively. Contrast-enhanced endoscopic ultrasonography (CE-EUS) findings indicated a hypervascular adrenal mass, and EUS-guided fine needle aspiration (EUS-FNA) revealed clear cell carcinoma. Adrenalectomy confirmed metastatic clear cell carcinoma of the kidney.     

盆静脉浸润对直肠癌预后的意义

目的：探讨直肠癌盆静脉浸润对预后的影响。方法：484例中低位直肠癌经腹会阴联合切除术（APR）（共356例）、低位前切除术（LAR）（共128例）后，对肿瘤因素进行分类，依据复发与五年生成的随访结果，就盆静脉浸润进行多因素回顾性统计分析。结果：总的复发率为14．5％，累积的五年生存率为71．1％，其中盆静脉浸润者分别为：44．4％（52／117）、29％（34／117）。Cox风险比例模型多因素回归分析显示：盆静脉浸润对五年生存的影响具有独立特性。结论：直肠癌盆静脉浸润是影响五年生存具有独立特性的高危因素，是准确预测患者的预后、指导术后系统的辅助治疗及随访的重要指标，也是临床病理分期方案的基准。     

Anorectal melanoma: report of three cases with extended follow-up

Primary anorectal melanoma is rare. There is controversy regarding the best surgical treatment because of its poor prognosis. Three cases with extended follow-up are reported in this article. A 53-year-old woman with rectal bleeding was diagnosed with a melanoma of the rectum and underwent an abdominoperineal resection. The patient died with distant metastases 8 months later. An 80-year-old woman with rectal bleeding was diagnosed with a melanoma of the rectum and underwent a transanal local excision. She remains alive 4 years later but with locally recurrent disease. A 78-year-old man with rectal bleeding was diagnosed with a melanoma of the rectum and underwent an abdominoperineal resection. He died with local and metastatic disease 25 months later. Recent trends favor local excision when technically feasible, although some patients may require an abdominoperineal resection of the rectum, especially for larger tumors.     

Hybrid resection of massive rectal gastrointestinal stromal tumor using laparoscopic and transanal approaches

Rectal gastrointestinal stromal tumors (GISTs) are rare, and radical surgery such as abdominoperineal resection is necessary for large rectal GISTs to obtain tumor-free resection margins. Here, we describe a 77-year-old man with a locally advanced non-metastatic GIST in the left anterolateral wall of the lower rectum. Tumor size was estimated to be 73 mm, and invasion of the left seminal vesicle and prostate was suspected. Chemotherapy with imatinib mesylate reduced the tumor size, creating a slight gap between the tumor and anterior organs. Therefore, we performed sphincter-sparing partial rectal resection using a hybrid method of laparoscopic and transanal approaches. The postoperative course was uneventful, and the patient remains disease-free on adjuvant chemotherapy 12 months after surgery. This case suggests that a hybrid method of laparoscopic and transanal surgery allows oncological and function-preserving excision of large rectal GISTs.     

Computed tomography of the large bowel and appendix

Computed tomography (CT) of the colon is useful in assessment of patients with colonic disease because the entire bowel wall, extraluminal tissues, and adjacent solid organs can be directly visualized. Patients with advanced stage colorectal carcinoma can be reliably identified with CT. This information can assist in surgical planning for intraoperative irradiation and placement of a hepatic artery infusion catheter. CT is an important imaging modality in the postoperative evaluation for recurrent rectal cancer after abdominoperineal resection. CT-guided biopsy often can provide histologic proof of suspected tumor recurrence or metastasis. Patients with diverticulitis or appendicitis can be identified by CT. The extent of disease and the nature of the inflammatory process--factors potentially affecting patient management--can be directly visualized. Percutaneous aspiration and drainage of abscess collections can be curative in appropriately selected patients.     

超声内镜引导细针穿刺抽吸术精准诊断胃癌术后胰腺转移癌一例

Sphincter preservation in rectal cancer: possibilities and limits of anterior resection

The feasibility of sphincter preservation was studied in surgery of tumours in the upper, middle and lower third of the rectum. All patients operated on for rectal cancer between January 1977 and May 1980 were included in the investigation. Preoperative localization of the tumours was performed with the rigid sigmoidoscope. Every patient was scheduled for post-operative follow up. Altogether 211 patients were operated on for rectal cancer. 111 were treated by anterior resection, 90 by abdominoperineal excision, and 10 by other sphincter-saving methods. All of the 59 tumours located in the upper third of the rectum (12 to 16 cm from the anus) were treated by anterior resection. 62 tumours were located in the middle third (8 to 12 cm). In these cases anterior resection was carried out in 60% of the men and in 82% of the women, whereas the other patients underwent abdominoperineal excision. 80 tumours were located in the lower third (4 to 8 cm). Anterior resection was possible in only 4.4% of the men and in 14% of the women. Irrespective of their localization on sigmoidoscopy, 37% of the tumours which were within reach of the finger on rectal palpation could be removed by anterior resection. Local recurrence after anterior resection occurred in 18.3%, the median follow-up time being 50 months. The cumulative probable survival for all stages was more than 5 years for 60% of the patients.     

Laparoscopic abdominoperineal resection with lateral lymph node dissection for anorectal melanoma: A case report

Because anorectal melanoma, a rare cancer with a poor outcome, does not respond well to local radiation therapy or systemic chemotherapy, surgery is the primary treatment. Herein, we present a case of anorectal melanoma with lateral and inguinal lymph node metastases. A 61‐year‐old woman presented with rectal bleeding. Colonoscopy revealed a black tumor with ulceration in the anorectum. A CT scan revealed an anorectal tumor with left lateral lymph node swelling and right inguinal lymph node swelling. We performed a laparoscopic abdominoperineal resection with lateral lymph node dissection and right inguinal lymph node dissection. One year after the initial operation, pulmonary metastases were observed, and pulmonary resection was performed. After the pulmonary resection, brain metastases developed, and surgical resection was performed. Despite the recurrence of disease, the patient has survived for 52 months since the initial surgery and continues to receive systemic chemotherapy.     

A case of successful laparoscopic intraperitoneal onlay mesh plus technique repair for perineal hernia after laparoscopic abdominoperineal resection

The frequency of secondary perineal hernia after abdominoperineal resection has been reported as 0.83%-26%. The optimal surgery for secondary perineal hernia and surgical indication remains controversial. An 87-year-old woman diagnosed with lower rectal cancer underwent laparoscopic abdominoperineal resection. Follow-up computed tomography at 6 months postoperatively revealed secondary perineal hernia. She reported no discomfort and no incarceration was apparent, but she complained of perineal discomfort 3 months later. Laparoscopic repair surgery was performed using an intraperitoneal onlay mesh plus technique with VENTRALIGHT® ST mesh (Medicon, Osaka, Japan), a non-absorbable mesh with a biodegradable coating. No recurrence of peritoneal hernia was seen as of 3 months postoperatively. A time lag can exist between imaging findings and symptom appearance. This laparoscopic intraperitoneal onlay mesh plus technique might become the optimal treatment for perineal hernia.     

Dynamic graciloplasty versus implant of artificial sphincter for continent perineal colostomy after Miles' procedure: Technique and early results

Abdominoperineal resection (APR) is still the standard surgical treatment of anorectal cancers close to the dentate line. Unfortunately, a permanent iliac colostomy is a severe limitation of the quality of life. Attempts to construct a continent perineal colostomy after anorectal excision have been made over the last 15 years with uncertain benefits. We report on our early results of two different procedures consisting of a laparoscopic approach to abdominoperineal rectal excision, fashioning a perineal colostomy with dynamic graciloplasty or implant of an artificial sphincter. Between 2000 and 2004, a total of six patients underwent laparoscopic abdominoperineal resection or reversal of Miles' procedure and construction of perineal colostomy with dynamic graciloplasty (three cases) or implant of an artificial bowel sphincter (three cases). A diverting loop ileostomy was constructed in all patients to prevent contamination. Data concerning the perioperative management, postoperative morbidity and mortality and function after total anorectal reconstruction at the time of discharge, at postoperative month 1 and after ileostomy closure were collected and evaluated in a prospective non-randomised fashion. No early postoperative complications occurred in both groups. No late complication occurred in the dynamic graciloplasty group, whilst one patient of the artificial sphincter group had an ulceration of the tubing and the control pump through the suprapubic skin and the labium skin respectively on postoperative day 35. Another patient in this group, with an erosion of the transposed colon wall, died of myocardial infarction on postoperative day 75 after removal of the prosthesis. Postoperative stay after artificial sphincter implant and dynamic graciloplasty ranged from 12 to 27 days and 16 to 24 days, respectively. The loop ileostomy was closed at postoperative month 3 in all remaining patients except for one in the dynamic graciloplasty group, who died one day before hospitalization for ostomy closure because of an accidental, not disease/operation related reason. Follow-up of patients of the dynamic graciloplasty and artificial sphincter groups ranged from 3 to 24 months and 2.5 to 9.5 months, respectively. Patients in the dynamic graciloplasty group had no complications and follow-up showed satisfactory continence (SF36 form). All patients in the artificial sphincter group had late local complications with erosion of the prosthesis through the wall, its consequent removal and construction of a permanent iliac colostomy. Laparoscopic APR has been reported to be as safe as open APR. There are no published, available data on laparoscopic APR and laparoscopic reversal of Miles' procedure with total anorectal reconstruction with either dynamic graciloplasty or implant of artificial sphincter. Preliminary results showed that laparoscopic APR and APR reversal with continent perineal colostomy and dynamic graciloplasty may be a possible option in selected patients whilst the implant of an artificial sphincter should not be considered as a safe surgical option in such patients.     

Intra‐abdominal desmoid tumor after laparoscopic low anterior resection for rectal cancer: A case report

Desmoid tumors are monoclonal fibroblastic proliferations arising from soft tissue classified as intra‐abdominal, extra‐abdominal and abdominal wall types. We present a patient with an intra‐abdominal desmoid tumor diagnosed 20 months after laparoscopic resection of rectal cancer. A 70‐year‐old woman with hematochezia was diagnosed with advanced rectal cancer. Preoperative chemoradiotherapy followed by laparoscopic low anterior resection was performed. During follow‐up, a nodular soft‐tissue density measuring 28 mm was detected in the presacral region. Metastasis from rectal cancer was diagnosed and four courses of chemotherapy were given, including capecitabine, oxaliplatin and bevacizumab. Computed tomography scan showed that the mass slightly decreased in size and surgical resection was performed. Histopathological examination revealed a proliferation of spindle‐shaped cells and collagenous stroma diagnosed as a desmoid tumor. This report highlights the possibility of a desmoid tumor in the differential diagnosis of an intra‐abdominal mass found during follow‐up after resection of colorectal cancer including following laparoscopic resection.     

Evaluating patients with mildly elevated transaminase levels

CASE STUDY: S.B. is a 52-year-old woman with recurrent stage IV ovarian cancer. She initially presented three and a half years ago with complaints of abdominal pain, increased abdominal girth, and abdominal bloating. A CA-125 blood test was elevated, and a computed tomography scan of the abdomen and pelvis revealed bilateral ovarian masses highly suspicious for malignancy. She was taken to surgery for a total abdominal hysterectomy, bilateral salpingo-oophorectomy, and suboptimal tumor reduction. Pathology revealed poorly differentiated papillary serous ovarian cancer. Metastatic disease was noted in the rectosigmoid area and vaginal apex. Postoperatively, she received six cycles of paclitaxel and carboplatin. At completion, her CA-125 normalized and imaging studies showed no evidence of disease. However, within three months, her CA-125 was elevated and a palpable mass at the vaginal apex was proven by biopsy to be recurrent disease.     

Port-site metastasis of unsuspected gallbladder carcinoma with ossification after laparoscopic cholecystectomy: A case report

BACKGROUNDUnsuspected gallbladder carcinoma (UGC) refers to cholecystectomy due to benign gallbladder disease, which is pathologically confirmed as gallbladder cancer during or after surgery. Port-site metastasis (PSM) of UGC following laparoscopic cholecystectomy is rare, especially after several years.CASE SUMMARYA 55-year-old man presenting with acute cholecystitis and gallstones was treated by laparoscopic cholecystectomy in July 2008. Histological analysis revealed unexpected papillary adenocarcinoma of the gallbladder with gallstones, which indicated that the tumor had spread to the muscular space (pT1b). Radical resection of gallbladder carcinoma was performed 10 d later. In January 2018, the patient was admitted to our hospital for a mass in the upper abdominal wall after surgery for gallbladder cancer 10 years ago. Laparoscopic exploration and complete resection of the abdominal wall tumor were successfully performed. Pathological diagnosis showed metastatic or invasive, moderately differentiated adenocarcinoma in fibrous tissue with massive ossification. Immuno-histochemistry and medical history were consistent with invasion or metastasis of gallbladder carcinoma. His general condition was well at follow-up of 31 mo. No recurrence was found by ultrasound and epigastric enhanced computed tomography.CONCLUSIONPSM of gallbladder cancer is often accompanied by peritoneal metastasis, which indicates poor prognosis. Once PSM occurs after surgery, laparoscopic exploration is recommended to rule out abdominal metastasis to avoid unnecessary surgery.     

Laparoscopic high anterior resection for rectal cancer with rare variations of the left renal vessels: A case report

We present a case of rectal cancer with rare variations of the left renal vessels. A man in his 60s underwent endoscopic mucosal resection for an Ip‐type lesion in the upper rectum. Histologically, the lesion was a well‐differentiated adenocarcinoma that had invaded the deep submucosal layer. Therefore, additional resection of the rectum with regional lymph node dissection was recommended. Preoperative CT revealed rare variations of the left renal vessels. There were two left renal arteries and veins; the caudal left renal artery and vein were located between the inferior mesenteric artery and the abdominal aorta. During the operation, these renal vessels were confirmed, and laparoscopic high anterior resection was performed safely without any injury to these renal vessels. To avoid the risk of unexpected intraoperative injuries, it is important to preoperatively check whether there are any variations in the renal vessels, even before colorectal surgery.     

影响低位直肠癌手术保肛相关因素的研究

目的分析影响低位直肠癌手术保肛的相关因素。方法将341例低位直肠癌患者按是否施行保肛手术而分为APR组和SP组，对两组病例临床资料（包括肿瘤下缘距肛缘的距离、患者年龄、性别、BMI）及病理资料（包括肿瘤周径、肿瘤位置、肿瘤大体分型、分化程度和Dukes分期）进行比较分析。结果APR组肿瘤下缘距肛缘距离显著小于SP组，肿瘤周径小于1／2周、1／2～3／4周、大于3／4周及全周四者保肛率依次下降（P〈0．01），对于肿瘤周径小于1／2周者，肿瘤主体位于后壁、侧壁及前壁者三者保肛率依次下降，但无明显统计学意义（P〉0．05）。肿瘤大体分型中，肿块型、溃疡型及浸润型三者保肛率依次下降（P〈0．05），肿瘤病理呈高、中、低分化癌者三者保肛率逐渐下降（P〈0．01），低位直肠癌Dukes A、B、C、D期四者保肛率呈逐渐下降趋势。青年人、男性、BMI≥23的患者其保肛率显著低于中老年人、女性及BMI〈23的患者（P〈0．05）。结论肿瘤下缘距齿状线或肛缘的距离是低位直肠癌手术保肛最主要的影响因素，肿瘤周径、肿瘤病理分期、肿瘤主体位置、肿瘤大体分型、肿瘤分化程度及患者的性别及BMI等均可对低位直肠癌手术保肛产生影响。     

Infantile myofibromatosis of the triceps detected by prenatal sonography

A routine prenatal sonographic examination at 36 weeks' menstrual age revealed a solid and slightly inhomogeneous soft-tissue tumor on a fetus's left upper arm. The mass in the left triceps brachii muscle measured 8 x 7 x 5 cm at birth. Because of progressive flexion contracture of the left elbow joint, at 2 months of age the infant underwent radical resection of the tumor, sparing some muscle fibers. Light microscopic and immunohistochemical studies revealed myofibromatosis. Neither tumor nor functional disorder of the arm was evident 3 years after surgery.

Endoscopic ultrasound-guided fine-needle aspiration in the evaluation of gallbladder masses

BACKGROUND AND STUDY AIMS: There are very few data on endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of gallbladder masses. The aim of this study was to assess the utility and safety of EUS-FNA in the evaluation of patients with gallbladder masses. PATIENTS AND METHODS: Six patients who underwent EUS-FNA of gallbladder masses over a 2-year period between 2002 and 2004 were studied retrospectively. Reports of endoscopic ultrasound (EUS) procedures, EUS images, cytology results, and clinical records were reviewed. Abdominal computed tomography (CT) prior to EUS had revealed a definitive gallbladder mass in only one of the six patients and no gallbladder masses were identified in any of the patients who had undergone prior transabdominal ultrasound. RESULTS: At EUS, all the patients were found to have an echo-poor mass arising from the gallbladder wall or within the lumen of the gallbladder. EUS-FNA of the gallbladder masses revealed adenocarcinoma in five patients and benign disease in one patient. After a mean follow-up period of 127 days (range 90 - 187 days), three patients had died, two were undergoing palliative chemoradiotherapy, and one had been confirmed as having chronic cholecystitis at surgery. No complications occurred. CONCLUSIONS: In patients with obstructive jaundice and equivocal ultrasound or CT findings, evaluation of the gallbladder for the presence of a primary malignancy by EUS is useful. In patients with gallbladder masses, EUS-FNA can be performed safely and can help to make a definitive diagnosis.
