Most of malignant tumors arising in ovarian and extraovarian endometriosis are carcinomas. Mixed mullerian tumor and endometrial stromal sarcoma arising in intestinal endometriosis are rarely described, but its clinicopathologic features have not been well characterized. Here we report a case of endometrial stromal sarcoma of the sigmoid colon arising in endometriosis with a review of six additional cases of endometrial stromal sarcoma arising in intestinal endometriosis found in English literatures. The patients ranged in age from 36 to 64 yr. Presenting symptoms were pain, bloody diarrhea, and tenesmus. Some patients had a previous history of endometriosis. Most of the tumors arose in the rectosigmoid colon. The histologic features were the same as their uterine counterpart. No death of disease had been reported. This rare tumor should not be confused with gastrointestinal stromal tumor clinically and histologically.

2.Standardization in performing regional lymph node dissection for rectum and sigmoid colon cancer.
Chinese Journal of Gastrointestinal Surgery 2022;25(4):309-314
Tumor spreading through the lymphatic drainage is an important metastatic pathway for rectum and sigmoid colon carcinoma. Regional lymph node dissection, as an important part of radical resection of colorectal cancer, is the main way for patients with colorectal cancer to achieve radical resection and acquire tumor-free survival. The regional lymph nodes of sigmoid cancer include paracolic lymph nodes, intermediate lymph nodes, and central lymph nodes locating at the root of blood vessel, and radical surgery should include lymph node dissection at the above three stations. The lymphatic pathways of metastasis for rectal cancer include longitudinal metastasis within the mesorectum and lateral metastasis beyond the mesorectum. The standard surgical method of rectal cancer is total mesorectal excision (TME) at present, and the resection range includes the metastatic lymph nodes within the mesorectum through the longitudinal pathway. However, there are many different opinions about lateral lymph node dissection(LLND) aiming at the metastatic lymph nodes locating at the lateral space of rectum. The range of lymph node dissection for rectum and sigmoid cancer is a vital factor that determines the prognosis of patients. Insufficient range of dissection can lead to residual metastatic lymph nodes and have serious impacts on the prognosis of patients. Excessive range of dissection can result in greater surgical trauma, prolonged operation time, more blood loss, and higher rate of complication without oncological benefits. Individualizating the appropriate resection range of rectum and sigmoid colon cancer on the basis of standardization and according to the clinical stage and invasion range of tumor demonstrates great significance of ensuring the radical operation, reducing trauma, promoting rehabilitation, protecting the function and improving the prognosis.

PURPOSE: The prognosis following colonic perforation is generally regarded as worse than it is for upper gastrointestinal perforation. Moreover, the increasing incidence of colon cancer associated perforation is another reason for the present study of colonic perforation in the present study. We reviewed and analyzed various types of colonic perforations to determine which prognostic factors were still useful for the treatment of colonic perforation. METHODS: Thirty six patients (mean age, 51.5; 24 males) with generalized peritonitis secondary to a colonic perforation were studied retrospectively. All the patients had undergone an exploratory laparotomy. The severity of the clinical condition was recorded according to the APACHE III scoring system for all the patients when they were first seen. Mortality and morbidity were analyzed for possible prognostic factors, such as age, type of operation, association with malignancy, and APACHE-III score. RESULTS: Penetrating trauma was the leading cause of perforation (27.8%), and iatrogenic perforations accounted for 19.4% of the total. Among nontraumatic perforations, malignancy was the major pathology (25.0%). The sigmoid colon was the most frequent site of perforation. Types of surgical treatment varied according to the general conditions of the patients. In 22 patients, the operation was finished with primary closure alone. A colonic resection was performed in 14 patients, and a proximal diversion was performed in 19 patients (after either a resection or primary closure). Analysis of the various clinical variables showed that old age (>60), underlying malignancy, and the APACHE III score were significant prognostic factors for the surgical outcome. CONCLUSIONS: These results suggest that penetrating injuries are still the main cause of colonic perforation and that iatrogenic and malignancy-related perforations are increasing. Among other variables, old age, underlying malignancy and the APACHE III score are significant prognostic factors for the surgical outcome.

Among women with intestinal endometriosis, the sigmoid colon and rectum are the most commonly involved areas. Sometimes, the differential diagnosis of colorectal endometriosis from carcinoma of the colon and rectum is difficult due to similar colonoscopic and radiologic findings. From October 2002 to September 2007, we performed five operations with curative intent for rectal and sigmoid colon cancer that revealed intestinal endometriosis. Colonoscopic and radiologic findings were suggestive of carcinoma of rectum and sigmoid colon, such as rectal cancer, sigmoid colon cancer and gastrointestinal stromal tumor (GIST). Anterior resection was performed in two patients, low anterior resection was performed in one patient and laparoscopic low anterior resection was done in two patients. We suggest to consider also intestinal endometriosis in reproductive women presenting with gastrointestinal symptoms and an intestinal mass of unknown origin.

Hepatocellular carcinoma (HCC) is a major health problem worldwide, and it has a poor prognosis. Extrahepatic metastasis from HCC is not unusual, with direct invasion representing the main spreading mode. Sites that are frequently involved are the lung, bone, and lymph nodes. There are few reports of HCC invading the distant gastrointestinal tract, especially hematogenously. Herein we report a case of sigmoid colon metastasis from HCC. The patient was diagnosed with HCC and treated with transcatheter arterial chemoembolization (TACE). Eighteen months after TACE the patient presented with abdominal pain on the left lower quadrant, and a CT scan showed an enhanced mass on the sigmoid colon. Immunohistochemical staining revealed that a tumor cell was positive for polyclonal carcinoembryonic antigen and weakly positive for hepatocyte antigen, supporting the diagnosis of HCC metastasis. The patient underwent anterior resection for the metastatic HCC.

Congenital infantile fibrosarcoma (CIF) is a rare soft-tissue tumor in the pediatric age group and seldom involves the gastrointestinal tract. A 2-day-old boy was transferred to our hospital with a pneumpoperitoneum. After emergency operation, we could find a solid mass wrapping around a sigmoid colon and performed a segmental resection of sigmoid colon including a mass. Histopathologic examination showed an infantile fibrosarcoma origining from the muscular layer of colon. The baby was discharged on the 17th hospital day and followed for 1 yr without recurrence.

OBJECTIVETo investigate the pattern of lymph node metastasis in patients with left-sided colon cancer in order to provide evidences for the choice of operation mode and the range of lymph node clearance.
METHODSClinical data of 556 cases with left-sided colon carcinoma undergoing surgical treatment in Department of Colorectal Surgery, Fujian Medical University Union Hospital from January 2000 to October 2014 were retrospectively analyzed. Among these patients, cancer of splenic flexure and transverse colon close to splenic flexure (splenic flexure group) was found in 41 cases, descending colon cancer in 73 cases(descending colon goup) and sigmoid colon cancer in 442 cases (sigmoid colon group), respectively; T1 was found in 29 cases, T2 in 63 cases, T3 in 273 cases, T4 in 191 cases. All the patients underwent D3 radical operation or complete mesocolic excision(CME). Para-bowel lymph node was defined as the first station, mesenteric lymph node as the second station, and lymph node in root of mesentery and around upper and inferior mesenteric arteries as the third station. Metastasis was compared among these 3 stations with regard to different sites and tumor invasions.
RESULTSThe total lymph node metastasis rate was 49.6%(276/556). The lymph node metastasis rates of splenic flexure, descending colon and sigmoid colon groups were 53.7%(22/41), 52.1%(38/73) and 48.9%(216/442) respectively without significant difference (P>0.05). The lymph node metastasis rates of the first, second, and third stations were 47.3%(263/556), 16.9%(94/556) and 5.8%(32/556) respectively with significant difference (χ(2)=287.54, P=0.000). In the first, second and third station, the lymph node metastasis rate was 13.8%(4/29), 0 and 0 in T1; 25.4%(16/63), 4.8%(3/63) and 3.2%(2/63) in T2; 45.8%(125/273), 14.7%(40/273) and 4.8%(13/273) in T3; 61.8%(118/191), 26.7%(25/191) and 8.9%(17/191) in T4 respectively. In splenic flexure group, metastasis rates were similar between No.222 and No.232[14.6%(61/41) vs. 12.2%(5/41), χ(2)=0.11, P=1.000] and between No.223 and No.253 [7.3% (3/41) vs. 2.4% (1/41), χ(2)=1.05, P=0.616]. In descending colon group, metastasis rate of No.232 was higher as compared to No.222[15.1%(11/73) vs. 2.7% (2/73), χ(2)=6.84, P=0.017]; metastasis rate of No.253 was slightly higher as compared to No.223 without significant difference [4.1%(3/73) vs. 0, χ(2)=3.06, P=0.245]. Metastasis rates of No.222 and No.223 in splenic flexure group were significantly higher than those in descending colon and sigmoid colon groups (χ(2)=5.69, P=0.025; Fisher exact test, P=0.044); While such rates of No.232(No.242 for sigmoid colon group) and No.253 were not significantly different among 3 groups respectively (χ(2)=0.90, P=0.660; χ(2)=1.14, P=0.611).
CONCLUSIONSLeft-sided colon cancers in T1 should undergo D2 radical operation, while cancers in T2 to T4 should undergo D3 radical operation. The D3 radical operation for splenic flexure cancers and cancers of transverse colon close to splenic flexure should clear No.223 and No.253. The D3 radical operation for descending colon cancer should clear No.222 and No.253. The D3 radical operation for sigmoid colon should clear No.253.

BACKGROUND: This nationwide survey was undertaken to characterize the general pathological features of colorectal cancer in Korea, and especially to elucidate the geographical characteristics by means of their anatomical distribution. METHODS: We analysed 1,676 colorectal cancers (from 1,602 patients) surgically resected in 1998 at 15 institutions from nine geographical sites in Korea. RESULTS: The topographic incidence of colorectal cancer in seven out of the total nine geographical sites, was the highest in the rectum (32-54%); and those from Wonju and Cheongju were in the sigmoid colon (28% for both). The right colon cancer incidence was 42% in Wonju and 36% in Cheongju, while it was 17-22% in the other areas. The cecal cancer incidences in Wonju and in Taegu were 7% and 8%, respectively, but 0-4% in the other areas. As for histology, moderately differentiated adenocarcinoma was the most frequent (46-84%), except for in Wonju and Chonju, where the most predominant type was well differentiated (63% and 52%, respectively). CONCLUSION: The incidence of right colon cancer was higher in Wonju and Cheongju, than in the other geographical sites. The cecal predilection was prominent in Taegu and Wonju. The Elucidation of geographical differences in degree of differentiation for tubular adenocarcinoma seems to require further cumulative study with strict guidelines.
