Project description:BackgroundTo test the feasibility of laparoscopic approach in performing the simultaneous pelvic autonomic nerve preservation during standard anterior resection of sigmoid colon cancer.MethodsPatients meeting appropriate eligibility criteria were recruited for the present study. The surgical procedures are shown in the video. The genitourinary function was evaluated on the basis of validated questionnaires including International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF), and Female Sexual Function Index (FSFI).ResultsA total of 112 patients (tumor, node, metastasis system stage I, n = 8; stage II, n = 54; stage III, n = 50; male, n = 58; female, n = 54; age [mean +/- standard deviation], 55.8 +/- 6.4 years) with good baseline genitourinary function were operated on with the intent of total preservation of pelvic autonomic nerves and curative resection of sigmoid colon cancer. The patients were prospectively followed (median time of follow-up, 18 months; range, 6-30 months). In patients with a successful nerve-preserving surgery (96.4%, n = 108), 104 patients completed the evaluation of urinary function. The median duration for indwelling urine Foley catheter was 3.0 days (range, 1.0-7.0 days). The voiding function after removal of the urine Foley catheter was good (IPSS, 0-7) in 98 (94.2%) patients, fair (IPSS, 8-14) in 5 (4.8%), and poor (IPSS, 15-35) in 1 (1.0%). Before and after nerve-preserving surgery, there were no significant changes of IPSS scores (3.20 +/- 1.72 vs. 3.68 +/- 2.82, P = .075, paired t-test) in the present patient series. Forty-four male patients completed the postoperative evaluation of sexual function, and ejaculation was ranked as good in 40 (90.9%), fair (decrease in ejaculatory amounts) in 3 (6.8%), and poor (retrograde ejaculation, failure of ejaculation) in 1 (2.3%), whereas the potency was good (IIEF, 60-75) in 41 (93.2%), fair (IIEF, 44-59) in 2 (4.5%), and poor (IIEF, 5-43) in 1 (2.3%). Moreover, before and after a successful nerve-preserving operation, there were no significant changes of IIEF scores (72.4 +/- 4.6 vs. 70.3 +/- 8.4, P = .082, paired t-test). For female patients (n = 42), the postoperative sexual function was ranked as good (FSFI score, 76-95) in 36 (85.7%), fair (FSFI, 58-75) in 4 (9.5%), and poor (FSFI, 4-57) in 2 (4.8%). Furthermore, there were no significant changes of FSFI scores (89.0 +/- 9.2 vs. 85.4 +/- 16.4, P = .122, paired t-test) before and after successful nerve-preserving surgery.ConclusionsUnder laparoscopy, we can clearly identify and preserve the pelvic autonomic nerves to retain genitourinary function in most patients undergoing oncologic resection of sigmoid colon cancer.

Project description:Reports on the laparoscopic treatment for colonic intussusception are exceedingly rare. We report a case of colonic intussusception caused by sigmoid colon cancer which was treated with a laparoscopic approach. A 76-year-old man visited an emergency room with the chief complaint of lower abdominal pain. He was diagnosed with colonic intussusception probably due to sigmoid colon cancer on a CT scan. Upon laparoscopic exploration, sigmoid colon intussusception was noted. Manual reduction was impossible because the colonic walls were friable and due to the possibility of a cancerous leading point. Therefore, the bowel was resected with en bloc Hartmann procedure. Pathology of the resected specimen revealed a tumor measuring 4.5 cm in size and comprising moderately differentiated adenocarcinoma (pT3N0M0, pStage II). The patient's postoperative course was uneventful and was discharged on the 8th day after surgery.

Project description:AimsThis study sought to evaluate the prognostic significance of postoperative complications for colon cancer patients undergoing laparoscopic surgery.MethodsFrom May 2006 to May 2009, a total 224 patients who underwent laparoscopic curative resection (R0) for colon cancer were included in our retrospective study. Postoperative complications were evaluated according to a standardized grading system. The main outcome measurements of our study were overall survival (OS) and relapse-free survival (RFS), which were then compared between the no complication and complication groups. Univariate and multivariate analysis were used to assess the correlation between complications and prognosis.ResultsFifty-nine postoperative complications occurred in 43 patients. The overall morbidity rate was 26.3%. The 5-year OS in the complication group was 41.4% compared with 78.5% in the no complication group (P<0.001). The cumulative incidence of relapse was also more aggressive in patients with complications (5-year RFS: complication group 40.9% vs. no complication group 82.1%, P<0.001). Multivariate analysis identified complications as a significant factor increasing the risk for both OS (RR 2.737; 95% CI 1.512-4.952; P = 0.001) and RFS (RR 4.247; 95% CI 2.291-7.876; P<0.001).ConclusionPostoperative complications could pose a significant adverse impact not only on OS but also on RFS in patients with colon cancer even when laparoscopic R0 resection is available.

Project description:PurposeEmerging evidence supporting the use of laparoscopic colectomy in patients with cancer has led to dramatic increases in utilization. Though certain patient and hospital characteristics may be associated with the use of laparoscopy, the influence of geography is poorly understood.MethodsWe used national Medicare claims data from 2009 and 2010 to examine geographic variation in utilization of laparoscopic colectomy for patients with colon cancer. Patients were assigned to hospital referral regions (HRRs) where they were treated. Multivariable logistic regression was used to generate age, sex, and race-adjusted rates of laparoscopic colectomy for each HRR. Patient quintiles of adjusted HRR utilization were used to evaluate differences in patient and hospital characteristics across low and high-utilizing HRRs.ResultsA total of 93,786 patients underwent colon resections at 3,476 hospitals during the study period, of which 30,502 (32.5%) were performed laparoscopically. Differences in patient characteristics between the lowest and highest quintiles of HRR utilization were negligible, and there was no difference in the availability of laparoscopic technology. Yet adjusted rates of laparoscopic colectomy utilization varied from 0% to 66.8% across 306 HRRs in the United States.ConclusionThere is wide geographic variation in the utilization of laparoscopic colectomy for Medicare patients with colon cancer, suggesting treatment location may substantially influence a patient's options for surgical approach. Future efforts to reduce variation will require increased dissemination of training techniques, novel opportunities for learning among surgeons, and enhanced educational resources for patients.

Project description:BackgroundGastric cancer and colon cancer are rarely seen in clinic, but there are still related reports. For gastric cancer and simultaneous colon cancer, surgical resection is the main treatment. Traditional surgery requires an incision from xiphoid process to pubic symphysis. With the progress of minimally invasive technology, laparoscopic surgery is also used in the treatment of gastric cancer, but also in the abdominal incision to remove specimens and in vitro anastomosis of digestive tract. Taking specimens through the natural cavity as a new surgical method can not only reduce the abdominal incision, but also reduce the occurrence of wound-related complications. Here, we report a patient with gastric cancer and colon cancer who was treated in our hospital.Case summaryWe report a series of patients with gastric cancer and colon cancer. upper abdominal pain was treated in our hospital for 6 months. electronic gastroscopy showed large irregular ulcers on the lesser curvature of the gastric antrum and biopsy showed poorly differentiated adenocarcinoma of the gastric antrum. The enhanced CT of abdomen and pelvis showed irregular thickening of gastric antrum wall, irregular thickening of sigmoid colon wall and no obvious enlarged lymph nodes around. Further electronic enteroscopy showed that the sigmoid colon showed cauliflower protuberance, the intestinal cavity was slightly narrow, the intestinal wall was stiff, and the biopsy pathology showed moderately differentiated adenocarcinoma of the sigmoid colon. No obvious abnormality was found in serological tumor indexes. We diagnosed gastric cancer with sigmoid colon cancer and the patient received Laparoscopic subtotal gastrectomy and sigmoidectomy combined with natural orifice specimen extraction surgery. At present, 12 months after operation, no clear tumor recurrence was found in the metastasis.ConclusionWe should improve the understanding of gastric cancer and sigmoid cancer and combine examination with pathology to avoid misdiagnosis as metastatic cancer. Laparoscopic subtotal gastrectomy should be performed for tumors with no serosa invasion, body mass index <30 and tumor diameter <6.5 cm. Sigmoidectomy combined with natural nostril sampling is feasible.

Project description:The Clinical Outcomes in Surgical Therapy trial demonstrated that laparoscopic colectomy (LC) was equivalent to open colectomy (OC) for 30-day mortality, time to recurrence, and overall survival in colon cancer (CC) patients. Current use of LC for CC is not well known.Surgical data were reviewed for all patients randomized into a national phase III clinical trial for adjuvant therapy in stage III CC (North Central Cancer Treatment Group trial N0147). Colon resections were grouped as open (traditional laparotomy) or laparoscopic, including laparoscopic; laparoscopic assisted; hand assisted; and laparoscopic converted to OC. Statistical methods included nonparametric methods, categorical analysis, and logistic regression modeling.A total of 3,393 evaluable patients were accrued between 2004 and 2009; 53% were male, median age was 58 years, 86% were white, and 70% had a body mass index >25 kg/m(2). Two thousand one hundred thirteen (62%) underwent OC. One thousand two hundred eighty (38%) were initiated as laparoscopic procedures, 25% (n = 322) were laparoscopic, 32% (n = 410) were laparoscopic assisted, 26% (n = 339) were hand assisted, and 16% (n = 209) were LC converted to OC. Significant predictors of LC (vs OC) in multivariate models were T stage (T1 or T2 vs T3 or T4; p = 0.0286), and absence of perforation, bowel obstruction, or adherence to surrounding organs (p < 0.01 each). Increasing rates of LC were observed over time, with LC eclipsing OC in 2009 (p < 0.0001). Surgical efficacy, measured by lymph node retrieval, was similar, with the mean number of lymph nodes retrieved higher in the LC group (20.6 vs 19.5 nodes; p = 0.0006).This study demonstrated a steadily increasing use of LC for the surgical treatment of CC between 2004 and 2009, with LC preferred by study completion. Surgical efficacy was similar in stage III CC patients.

Project description:Introduction:Single-incision laparoscopic surgery (SILS) has benefits, including less postoperative pain, a shorter incision, and improved cosmesis. However, SILS is technically difficult because of the limited movement. An organ retractor is an instrument that has the potential to overcome these limitations. Presentation of case:An 85-year-old woman with hematochezia was referred to our hospital. Emergency endoscopy showed diverticulosis of the entire colon and active bleeding from the ascending colon. Despite endoscopic clipping, the bleeding continued. SILS total colectomy using an organ retractor was performed due to uncontrollable diverticular bleeding. A 3-cm incision was placed in the umbilicus, and three conventional ports were inserted into the single umbilical incision. An organ retractor was used for hepatocolic ligament transection, transection of the ileocolic vessels, and transection of the mesentery of the sigmoid colon. For each transection, the tension was adjusted to provide a good operative view. The patient's postoperative course was uneventful. Conclusion:An organ retractor was effective for SILS total colectomy to maintain an adequate operative view, which enabled safe dissection.

Project description:IntroductionIncarcerated inguinal hernia is an irreducible but the blood supply to the contained part is intact, but developing towards strangulation. Diagnosis usually made by physical examination. The content of hernia sac may vary. The usual finding is a segment of small intestine and less commonly large intestine. Except in sliding hernia, the sigmoid colon is not common in inguinal hernia, especially on the right side.Case reportWe report a rare case of an incarcerated right side inguinal hernia containing the sigmoid colon of a 65-year old male, diagnosed with physical examination and abdominal ultrasonography. This patient treated by reducing the content of hernia sac and herniorraphy in general surgery ward of Aliabad Teaching Hospital.DiscussionInguinal hernia is the commonest of all groin hernia. Incarcerated inguinal hernia can lead to intestinal obstruction, strangulation and infarction. The content of inguinal hernia varies widely. In our case, the content of hernia sac was the incarcerated loop of sigmoid colon. The sigmoid colon is commonly found to herniate at the left inguinal region, but as a content of a right side inguinal hernia is rare.ConclusionThe sigmoid colon as a content of a right side inguinal hernia is rare. Mesh repair has always been a subject of debate due to increased risk of mesh infection rates. Many patients present complications due to delayed elective repair of inguinal hernia.

Project description:Sigmoid volvulus is very uncommon cause of intestinal obstruction in pediatrics population withhigh rate of mortality. To date, few cases of sigmoid volvulus in children and association with several condition has been reported in literature, of them very few cases are with mental disability. We report a challenged (mentally disabled) 14-year old adolescent boy presented asan emergency with feature of complete bowel obstruction. Abdominal X-rays shows dilated loop of large bowel with inverted U shaped. Volvulus of sigmoid colon was found during laparotomy and successfully managed with resection of a redundant colon with colocolic end to end anastomosis. Sigmoid volvulus is relatively uncommon in children as compared to adults. Surgeons should be attentive of this rare entity, cause of large bowel obstruction to allow for early diagnosis and to enable better patient outcomes by reducing the morbidity and mortality.
