Arterias sigmoideas: bases para una nueva clasificación / Sigmoid arteries: bases for a new classification

Las arterias sigmoideas son ramas de la arteria mesentérica inferior e irrigan al colon sigmoideo. Se originan del tronco de las arterias sigmoideas. Esta es la descripción más frecuente según los autores consultados. El objetivo fue analizar las variaciones en el origen y distribución de las arterias sigmoideas mediante disección. Se utilizaron 13 preparados cadavéricos formolizados al 10 %. Se disecó la cavidad abdominal para identificar a las arterias sigmoideas. Se evidenció su bifurcación paralela al colon sigmoideo. Se lo delimitó mediante reparos palpables. Patrón I: 4 casos (30,8 %). Variante de la arcada sigmoidea como rama colateral de la arteria mesentérica inferior. Tipo Ia: 1 caso (25 %). Sin asociaciones. Tipo Ib: 1 caso (25 %). Asociada al tronco sigmoideo. Tipo Ic: 2 casos (50 %). Asociada a arterias sigmoideas accesorias. Patrón II: 6 casos (46,2 %). Variante del tronco común entre arteria cólica izquierda y arterias destinadas al colon sigmoideo. Tipo IIa: 3 casos (50 %). Sin asociaciones. Tipo IIb: 2 casos (33,3 %). Asociado al tronco sigmoideo. Tipo IIc: 1 caso (16,7 %). Asociado a arterias sigmoideas accesorias. Patrón III: 3 casos (23 %). Variante clásica. Se definió por la ausencia del tronco común con la arteria cólica izquierda y de la arcada sigmoidea. Tipo IIIa: 2 casos (66,7 %). Un número variable de arterias sigmoideas nacen como ramas colaterales de la arteria mesentérica inferior, sin asociarse al tronco sigmoideo. Tipo IIIb: 1 caso (33,3 %). La arteria cólica izquierda emite como rama colateral la primera arteria sigmoidea y se asocia al tronco sigmoideo. 1. El patrón II es el prevalente en este trabajo (46,2 %). 2. La variante clásica no es la predominante en esta investigación (23 %). 3. La arcada sigmoidea tiene 53,8 % de incidencia.

SUMMARY: The sigmoid arteries are branches of the inferior mesenteric artery and supply the sigmoid colon. They originate from the trunk of the sigmoids. This is the most frequent description according to the consulted authors. The objective is to analyze the variations in the origin and distribution of the sigmoid arteries through dissection. 13 cadaveric preparations formalized at 10 % and instruments were used. The abdominal cavity was dissected to identify the sigmoid arteries. Its bifurcation parallel to the sigmoid colon is evident. It is delimited by palpable repairs. Pattern I: 4 cases (30.8 %). Variant of the sigmoid arcade as a collateral branch of the inferior mesenteric artery. Type Ia: 1 case (25 %). No associations. Type Ib: 1 case (25 %). Associated with the sigmoid trunk. Type Ic: 2 cases (50 %). Associated with accessory sigmoid arteries. Pattern II: 6 cases (46.2 %). Variant of the common trunk between the left colic artery and arteries destined for the sigmoid colon. Type IIa: 3 cases (50 %). No associations. Type IIb: 2 cases (33.3 %). Associated with the sigmoid trunk. Type IIc: 1 case (16.7 %). Associated with accessory sigmoid arteries. Pattern III: 3 cases (23 %). Classic variant. It was defined by the absence of the common trunk with the left colic artery and the sigmoid arcade. Type IIIa: 2 cases (66.7 %). A variable number of sigmoid arteries arise as collateral branches of the inferior mesenteric artery, without being associated with the sigmoid trunk. Type IIIb: 1 case (33.3 %). The left colic artery gives off the first sigmoid artery as a collateral branch and is associated with the sigmoid trunk. 1. Pattern II is the most prevalent in this study (46.2 %). 2. The classic variant is not the predominant one in this research (23 %). 3. The sigmoid arcade has a 53.8 % incidence.

A case of recurrent ureteral terminal tumor after radical cystectomy and rectal bladder replacement / 中华泌尿外科杂志

For invasive bladder cancer, radical cystectomy and rectal substitution for sigmoid skin fistulas were commonly used in some medical centers. There is no report on the feasibility of sigmoid colon retraction except nephroureterectomy for patients with recurrent ureteral tumors after operation. We presented a case of recurrent ureteral tumors after rectal substitution bladder surgery for bladder cancer. Finally, left ureteral resection + sigmoid colon return + right ureteral skin stoma was successfully performed.The patient was followed up for 1 year without recurrence.

Correlation of endoscopic findings with suspected intestinal endometriosis in the distal sigmoid and rectum as observed on transrectal ultrasonography

Introduction: Colonoscopy enables detailed endoscopic evaluation of the interior of the colon. Changes observed via colonoscopy may be subtle or pronounced and can sometimes mimic those of other diseases, such as deep intestinal endometriosis. The diagnosis of endometriosis in the distal sigmoid and rectum by colonoscopy has been described in previous case reports. Objective: We aimed to correlate the endoscopic changes found in the distal sigmoid and rectum with the presence of endometrial deposits confirmed by transrectal ultrasound (TRUS). Methods: We included 50 female patients referred to the endoscopy department at our institution for colonoscopy, rectosigmoidoscopy, or TRUS, who exhibited one or more symptoms associated with endometriosis. Results: The colonoscopic findings were normal in 36 patients but showed alterations in 14 patients. Among the latter, TRUS revealed involvement of the sigmoid and/or rectal wall in 11 patients. Conclusions: The endoscopic changes in the distal sigmoid or rectum described in this study were strongly associated with endometrial deposits confirmed using TRUS. (AU)

PERFORATION OF THE SIGMOID COLON AFTER INGESTA OF A FOREIGN BODY.

Introduction: The ingestion of a foreign body (FB) is uncommon, yet important cause of gastrointestinal injury; it has more incidence in the pediatric population. Less than 1 % of the FB is associated with complications, particularly gastrointestinal perforations. We present the case of a 76 years old female, who refers Case report: lower quadrant abdominal pain of 48 hours of evolution, with gradually exacerbation over 1 day, The CT Findings reveal the presences of pneumoperitoneum and a high-density FB in the architecture of rectosigmoid colon, she underwent exploratory laparotomy with trans -surgical ?ndings: Perforation of 0.5 cm in rectosigmoid union, with the protrusion of a bone with perilesional edema. Treated with suturing in two planes, with good evolution. Most ingested FB Discussion and conclusions: pass through the GI tract uneventfully within 1 week, and is more common among children and older individuals. Patients with dentures, alcoholics and psychiatric patients are at high risk of FB ingestions. In the case of perforation due to foreign body, different techniques can be performed; the most common are: In the stomach, primary suture, in the small bowel, primary suture or segmental resection with anastomosis, and in the colon, sigmoid and rectum, primary suture, wound eversion by colostomy, segmental resection with anastomosis, and segmental resection with proximal colostomy

An Unusual Presentation of Congenital Megacolon with A Rare Vascular Anomaly A Case Report

Congenital megacolon also referred to as Hirschsprung’s disease or aganglionic megacolon is characterized by the absence of nerve plexus in the colon, it rarely affects the small intestine. Whereas acquired megacolon is a constant dilatation of the large intestine in the absence of disease but occurs due to various factors such as infections, emotional disturbances, stress, or secondary to inflammatory bowel diseases (IBD) such as ulcerative colitis, Crohn’s disease, and proctocolitis. In the present case, we report here an unusual form of megacolon. The sigmoid colon was significantly enlarged but twisting or volvulus was not detected. The ascending, transverse, and remaining part of descending colon and mesentery appeared normal, The possibility of false rotation of the gut was excluded. Interestingly, the artery supplying the left one-third of the transverse colon and descending colon originated from a branch of the middle colic artery. This anomalous artery was found to form a communication with the trunk of the inferior mesenteric artery, the Arc of Riolan, and gave branches that supplied the descending colon. The left colic artery was absent. The transverse colon showed a stricture between its right 2/3rd and left 1/3rd, confirming with vascular accidents, resulting in anomalous blood supply and aganglionosis. The dilated part of the sigmoid colon was found to be with ganglion cells, while the distal part after the megacolon, lacked ganglion cells in all layers of the sigmoid colon. This case documents a very rare finding which will make the surgeons aware of a newer arterial pattern associated with congenital megacolon.

Lymph node dissection and key technical points in 4K laparoscopic radical resection of mid-distal sigmoid colon cancer / 中华消化外科杂志

Colon cancer is a commonly malignant tumor with high morbidity and mortality in China, which seriously threatens human health and lives. Surgery plays a key role in the treatment of colorectal cancer so far. The sigmoid colon is the predilection site of colon cancer. Laparoscopic surgery has been gradually applied in radical operation of sigmoid colon cancer. 4K laparoscopy belongs to a kind of high-imaging technology, of which the information volume is more than 4 times that of conventional high-definition televisions. It can improve the operator's sense of control on the surgical field of view. Combined with team practical experience, the author introduces and interprets the excision extent and operative procedures in radical resection of mid-distal sigmoid colon cancer from the perspective of the 4K laparoscopy.

Irreducible Indirect Inguinal Hernia Caused by Sigmoid Colon Cancer Entering Right Groin:A Case Report / 中国医学科学院学报

We reported a case of irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.The patient complained about a right groin mass for more than 60 years with progressive enlargement for 3 years and pain for half a month.Abdominal CT examination at admission showed rectum and sigmoid colon hernia in the right inguinal area and thickening of sigmoid colon wall.Electronic colonoscopy and pathological diagnosis showed sigmoid colon cancer.Therefore,the result of preliminary diagnosis was irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.We converted laparoscopic exploration to laparotomy followed by radical sigmoidectomy and employed end-to-end anastomosis of descending colon and rectum in combination with repair of right inguinal hernia.The patient recovered well after operation and was discharged.

Lithobezoar: a case report

We present a unique case of a colonic lithobezoar in a relatively healthy, young male with no history of psychological or psychiatric disorders. Furthermore, unlike previously reported cases, this patient had no history of gastric surgery. The mode of presentation and the rariety of disease pose difficulties in diagnosis of lithobezoar. The different modalities of treatment, both surgical and nonsurgical, were thought of and discussed. The diagnosis of a lithobezoar in a healthy patient requires a high index of suspicion, as it presents with nonspecific symptoms. The standard treatment for bezoars is discussed but lithobezoar needs special mention due to its rariety and no specific surgery guidelines.

The Uncharted Danger of Living in the Tropics: A Needlefish Impalement of the Sigmoid Colon

@#Penetrating injury to the abdominal viscera is not uncommon unless when it is caused by marine life. We present a 39-year-old fisherman from a tropical country who had sustained a penetrating injury from a stab wound to the abdomen due to needlefish impalement. He sustained a small perforation of the sigmoid colon during exploratory laparotomy and primary repair was done. Although this incident is rare, there are cases involving seawater activities either for leisure, sport or diving for fishing. We highlight this rare incident and discuss the management plan.

How is Vaginal Function in Patients with A History of Sigmoid Vaginoplasty Surgery?

@#Introduction: Sigmoid colon vaginoplasty is a surgical procedure for the management of vaginal agenesis cases. This technique produces a neovagina that can function as a menstrual blood outlet as well as on penetration during sexual activity. Methods: A retrospective case study of vaginal agenesis, where sigmoid colon vaginoplasty surgery was performed at Dr. Sardjito Hospital Yogyakarta Indonesia in 2016-2018. The following post-surgical evaluation were assessed by observing the vaginal function to drain menstrual blood out, as well as function on penetration during sexual activity. Results: Sixteen cases of vaginal agenesis surgically performed were reported. Identification of the reproductive organs was carried out, in which 3 patients were without uterus, and 13 patients had menstrual uterine function. The length of sigmoid colon graft was around 15-20 cm. There were no complications during surgery. Post-surgical evaluation of 5 cases who have been married, all have been able to penetrate in sexual activity without meaningful complaints. All cases that had a uterus underwent regular menstrual cycles, with no dysmenorrhea. It can be said as a whole that this surgical procedure can be accepted by the patients, because it produced good vaginal function. Conclusions: Sigmoid colon vaginoplasty was a surgical procedure for congenital vaginal agenesis with satisfactory results. There were no complaints of dyspareunia or post-surgical dysmenorrhoea, resulting in a good cosmetic appearance of the external genitalia, and relatively mild complications.

A rare case of steroid cell tumor of ovary: case report

Steroid cell tumors of the ovary account for less than 0.1% of all ovarian tumors. These tumors may present at any age with presentations related to the hormonal activity and virilizing properties of tumor. A 61-year-old postmenopausal women presented with complaints of postmenopausal bleeding for 15 days. Parity score of P3L3, not tubectomised. Menopaused 16 years back. History of weight loss noted. She is a known case of diabetes mellitus for 6 years not on any treatment and a known case of depressive disorder for 35 years on treatment on trihexphenidyl lurasidone. Had undergone sigmoid colon polyp removal in June 2018. On examination, P/A- mild gaseous distension (+). P/S- cervix flushed with vagina, pulled up cervix. P/V- uterus size and position couldn’t be made out, anterior fornix fullness (+). Ultrasonography showed bulky uterus with fibroid 4x4cm, endometrial thickness- 9 mm? Krukenberg tumor and posterior mediastinal lymph nodes. Patient underwent Total abdominal hysterectomy with bilateral salpingo-oophorectomy with frozen section on 01/07/19. Frozen section: 1. Ovaries: right ovary - fibrothecoma, left ovary- simple cyst. 2. Uterus- endometrial hyperplasia with atypia. 3. Myometrium- leiomyoma and adenomyosis. Postoperative period was uneventful. On microscopic examination, impression: right ovary- steroid cell tumor, uterus-endometrial hyperplasia with cytological atypia. Ovarian steroid cell tumors are grouped under sex chord stromal tumors and are usually benign, unilateral and characterized by a steroid cell proliferation. Steroid cell tumors are associated with androgenic changes with variable frequency, ranging from 12% to over 50% respectively. The primary treatment is surgical extirpation of the primary lesion and there are no reports of effective radiation or chemotherapy. In a young patient with stage IA disease, a unilateral salpingo oophorectomy is adequate.

Sub-hepatic Caecum with Extra-pelvic Looped Sigmoid Colon: An Embryological and Clinical Perspective

Introduction: We encountered variation in the placementof large intestine in abdominal cavity of a 76-years-old malecadaver during dissection of abdominal cavity. The workwas performed in Department of Anatomy during routineMBBS teaching sessions. The aim of this paper is to reportco-existence of error of mid-gut development and alongwith variant topo-morphology of sigmoid colon in the samecadaver.Case Report: Sub-hepatic caecum with high riding vermiformappendix with absent ascending colon was seen on the rightside of abdominal cavity. Concomitantly on the left side of theabdominal cavity dilated, looped sigmoid colon occupied theleft hypochondrium, left lumbar region and left iliac fossa. Wereport these findings along with the embryological basis andclinical significance.Conclusion: An insight about the errors in development ofmid-gut resulting into the variant topography of caecum willfacilitate surgeons and radiologists in prompt diagnosis andquick modification of the protocol during invasive procedures.

Chronic Diarrhea Caused By an Impacted Foreign Body in the Sigmoid Colon: A Rare Scenario

Chronic diarrhea is a very common disease which affects the quality of life of our patients. It is one of the major diseases for which patients are referred to gastrointestinal clinics. Irritable bowel syndrome, infectious diarrhea and abdominal tuberculosis due to unhygienic conditions in our part of the world and inflammatory bowel disease are the major causes of chronic diarrhea in young patients. We are reporting a young female patient who presented with chronic diarrhea, abdominal pain and bleeding per rectum mimicking ulcerative colitis for last many months but on colonoscopy examination an impacted foreign body was found in the sigmoid colon which was the culprit. Surgical retrieval of the foreign body resolved the symptoms.

The clinica value of low ligaation of inferior mesenteric artery in non Ⅰ mesosigmoid laparoscopic Dixon / 实用肿瘤学杂志

Objective To explore the application value of low ligation of inferior mesenteric artery(IMA) in laparoscopic Dixon of nonⅠsigmoid colon mesangial(SMC). Methods Seventy-one cases of nonⅠSMC rectal cancer patients who evaluated for feasibility of laparoscopic Dixon in the Department of Gastrointestinal Surgery Affiliated Tumor Hospital of Xinjiang Medical University from September 2017 to July 2018 were selected in this study,and they were randomly divided into two groups:the group of left colic artery reserved(low ligation group)and the group of left colic artery not retained(high ligation group). A three-dimensional compu-ted tomography angiography of inferior mesenteric artery was obtained in all patients to guide the intraoperative accurate ligation of vessels. The baseline data,intraoperative and postoperative quantitative parameters of the two groups were compared. Results Three patients in the group of left colic artery reserved were forced to turn to high ligation for it could not meet the requirement of anastomo-sis. The low ligation group showed significant difference to the high ligation group on operation time[170(160,180) vs. 180 (170, 210)](P=0. 026),but there was no significant difference in the aspect of gender,age,BMI,distance between tumor and anal bor-der,TNM stage,intraoperative blood loss,the splenic free rate,prophylactic stoma rate,Length of specimen,maximum diameter of tumor,tissue typing,total lymph node count,D3 lymph node count,postoperative first exhaust time,days in hospital since surgery and anastomotic fistula rate(P>0. 05). Conclusion Low ligation of inferior mesenteric artery can shorten the operation time and signifi-cantly lessen unplanned bowel length and reduce postoperative risk of anastomotic leakage. All of these are beneficial to patients′post-operative recovery and have important clinical guiding value.

Pseudotumor de colon sigmoide / Sigmoid colon pseudotumor

Numerosas enfermedades clínicas pueden afectar la estructura o el funcionamiento normal del colon, cada vez son más frecuentes las tumoraciones, los procesos inflamatorios e infecciosos y los trastornos fisiológicos o mecánicos de ese órgano. Se presenta el caso de un paciente masculino, blanco, de 45 años de edad que 10 meses antes comenzó con dolor cólico en hemiabdomen superior izquierdo. Este dolor se desplazó gradualmente al flanco y fosa ilíaca de ese lado, moderadamente intenso, intermitente, sin relación prandial, acompañado de aerocolia, constipación que alternaba con heces blandas con flemas y pérdida de peso de aproximadamente 8 libras. En ese tiempo su salud empeoró gradualmente, por lo cual solicita atención médica. Se realizaron procederes endoscópicos y estudios imagenológicos, se detectó carcinoma de sigmoides. Se realiza laparotomía exploradora con escisión del órgano y se comprueba una formación granulomatosa que a su apertura se aprecia un cuerpo extraño con tejido fibroso y angiogénesis. A todo paciente que solicite atención médica por manifestaciones digestivas bajas de tiempo prolongado de evolución y que se le constate al examen físico una masa inflamatoria o tumoral en el colon, más aún en su parte izquierda, o que presente manifestaciones obstructivas, es imprescindible realizarle una minuciosa anamnesis que incluya la posible ingestión de un cuerpo extraño(AU)

Numerous clinical diseases can affect the colon structure or normal functioning. Tumors, inflammatory and infectious processes and physiological or mechanical disorders of that organ are increasingly frequent. We report the case of a male patient, white, 45 years old, who 10 months earlier began with colicky pain in the upper left hemiabdomen. This pain gradually shifted to the flank and iliac fossa on that side, becoming moderately intense, intermittent, without prandial relation, accompanied by aerocolia, constipation that alternated with soft stools with phlegm and weight loss of approximately 8 pounds. During this time, his health gradually worsened, which is why he requests medical attention. Endoscopic procedures and imaging studies were performed. Sigmoid carcinoma was detected. An exploratory laparotomy was performed with excision of the organ and a granulomatous formation was confirmed, which upon opening revealed a foreign body with fibrous tissue and angiogenesis. It is essential to perform a meticulous anamnesis including the possible ingestion of a foreign body to all patients who request medical assistance due to low digestive manifestations of long time of evolution and whose physical examination confirms an inflammatory or tumoral mass in the colon, even more in its left part, or to those presenting obstructive manifestations(AU)

Isolated Sigmoid Colon Injury Following Blunt Trauma Abdomen - An Unusual Occurrence.

Colon injury is far more common in penetrating injury than blunt trauma. Blunt trauma to the abdomen is more likely to damage solid organs such as the liver, spleen, pancreas and kidneys. Colon injury in blunt trauma is severe and is associated with other organ injuries, making its diagnosis difficult. However, isolated sigmoid colon injury in blunt trauma is rare. We report a case of 42 year old male who presented to us with blunt trauma to abdomen following a fall on iron Jaal (Grid) with slipping of one lower limb between two iron bars. The patient presented 4 days after injury with tenderness and guarding all over abdomen. X-ray abdomen was normal, ultrasonogram of abdomen showed presence of free fluid. Patient was operated on clinical basis. A single perforation of size 2 cm×1 cm was present in proximal sigmoid colon and there was no other injury. The perforated colon loop was mobilized and brought to anterior abdominal wall as colostomy. Isolated sigmoid colon injury is rare presentation. Initial radiologic investigations and clinical presentation may be misleading.

Endometriosis en colon sigmoides asociada a hematoquecia en una paciente histerectomizada / Endometriosis within the sigmoid colon associated with hematochezia in a hysterectomized woman

La endometriosis es la existencia e implantación de estroma y glándulas endometriales funcionales fuera del útero, pero con funcionalidad similar al tejido endometrial dentro de la cavidad uterina. Tiene una presentación clínica variable, ya que depende del sitio de implantación. Se ha determinado que es la tercera causa de hospitalización en los Estados Unidos. Se presenta el caso de una paciente de 44 años de edad con hematoquecia causada por endometriosis profunda infiltrante en colon sigmoides, después de once años de haberse realizado la histerectomía. La paciente fue tratada mediante resección quirúrgica debido a que se sospechaba de un carcinoma.

Endometriosis is the presence of functional ectopic endometrial tissue outside the uterine cavity. The clinical presentation is variable and depends on the location. It is considered the third leading cause of hospitalization in the United States. In this case, we report a 44-year-old woman with hematochezia caused by deep infiltrating endometriosis within the sigmoid colon, after having undergone a hysterectomy 11 years ago. The patient received surgical resection due to suspicion of carcinoma.

Comparison of the efficacy of two laparoscopic surgical procedures in patients with sigmoid colon cancer / 中国内镜杂志

Objective To compare the efficacy of traditional laparoscopic radical resection of sigmoid colon and rectal specimens without abdominal incision laparoscopic surgery. Methods From January 2015 to December 2016 in our hospital to implement selected laparoscopic assisted sigmoid colon cancer surgery patients in 34 patients with abdominal incision rectal specimens of laparoscopic sigmoid colon resection of colorectal cancer patients without abdominal incision group. As to the choice of 1 ~ 2 pairs in the same period of age, gender, as the control group were given laparoscopic assisted sigmoid colon body mass index similar to radical surgery in 68 patients with operation time. Comparing the two kinds of laparoscopic surgery, perioperative bleeding, postoperative exhaust time postoperative pain score, complications, surgery, postoperative hospital stay, additional analgesic treatment, length of bowel resection, proximal and distal margin, tumor size, lymph node dissection the number of pTNM staging. Results The abdominal surgery time without incision group of sigmoid colon cancer patients, intraoperative bleeding was significantly higher than control group, abdominal incision group of sigmoid colon cancer patients with postoperative exhaust time, postoperative pain awake score, postoperative 1 d pain score was significantly lower than the control group, there was statistical significance the difference (P < 0.05); the two group of sigmoid colon cancer patients with bowel resection length of proximal margin, tumor size, number of lymph node dissection, there was no significant difference in pTNM staging (P > 0.05). Abdominal incision group were followed up for 5~8 months, average 6 months; the control group were followed up for 6 ~ 9 months, an average of 7 in August, there were no tumor recurrence and metastasis. Conclusion Compared with traditional laparoscopic surgery, abdominal incision rectal specimens of laparoscopic radical resection of sigmoid colon cancer can significantly reduce the pain of patients, shorten the postoperative exhaust time, tumor root Treatment effect is similar
