Is prophylactic pelvic drainage useful after elective rectal or anal anastomosis?A multicenter controlled randomized trial

OBJECTIVE We investigated the role of drainage in the prevention of complications after elective rectal or anal anastomosis in the pelvis. Anastomotic leakage after colorectal resection is more prevalent when the anastomosis is in the distal or infraperitoneal pelvis than in the abdomen. The benefit of pelvic drains versus their potential harm has been questioned. Drain-related complications include (1) those possibly benefiting from drainage (leakage, intra-abdominal infection, bleeding) and (2) those possibly caused by drainage (wound infection or hernia, intestinal obstruction, fistula). METHODS Between September 1990 and June 1995, 494 patients (249 men and 245 women), mean age 66 +/- 15 (range 15 to 101) years, with either carcinoma, benign tumor, colonic Crohns disease, diverticular disease of the sigmoid colon, or another disorder located anywhere from the right colon to the midrectum undergoing resection followed by rectal or anal anastomosis were randomized to undergo either drainage (n = 248) with 2 multiperforated 14F suction drains or no drainage (n = 246). The primary end point was the number of patients with one or more postoperative drain-related complications. Secondary end points included severity of these complications as assessed by the rate of related repeat operations and associated deaths as well as extra-abdominally related morbidity and mortality. RESULTS After withdrawal of 2 patients (1 in each group) both groups were comparable with regard to preoperative characteristics and intraoperative findings. The overall leakage rate was 6.3% with no significant difference between those with or without drainage. There were 18 deaths (3.6%), 8 (3.2%) in those with drainage and 10 (4%) in those without drainage. Five patients with anastomotic leakage died (1%), 3 of whom had drainage. There were 32 repeat operations (6.5%) for anastomotic leakage 11 in the group with drainage and 4 in the group with no drainage. The rate of these and the other intra-abdominal and extra-abdominal complications did not differ significantly between the 2 groups. CONCLUSION Prophylactic drainage of the pelvic space does not improve outcome or influence the severity of complications.

Iterative Cytoreductive Surgery Associated With Hyperthermic Intraperitoneal Chemotherapy for Treatment of Peritoneal Carcinomatosis of Colorectal Origin With or Without Liver Metastases

Introduction:The aim of this study was to evaluate the results of an aggressive strategy in patients presenting peritoneal carcinomatosis (PC) from colorectal cancer with or without liver metastases (LMs) treated with cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Patients and Methods:The population included 43 patients who had 54 CS+HIPEC for colorectal PC from 1996 to 2006. Sixteen patients (37%) presented LMs. Eleven patients (25%) presented occlusion at the time of PC diagnosis. Ascites was present in 12 patients (28%). Seventy-seven percent of the patients were Gilly 3 (diffuse nodules, 5–20 mm) and Gilly 4 (diffuse nodules>20 mm). The main endpoints were morbidity, mortality, completeness of cancer resection (CCR), and actuarial survival rates. Results:The CS was considered as CCR-0 (no residual nodules) or CCR-1 (residual nodules <5 mm) in 30 patients (70%). Iterative procedures were performed in 26% of patients. Three patients had prior to CS + HIPEC, 10 had concomitant minor liver resection, and 3 had differed liver resections (2 right hepatectomies) 2 months after CS + HIPEC. The mortality rate was 2.3% (1 patient). Seventeen patients (39%) presented one or multiple complications (per procedure morbidity = 31%). Complications included deep abscess (n = 6), wound infection (n = 5), pleural effusion (n = 5), digestive fistula (n = 4), delayed gastric emptying syndrome (n = 4), and renal failure (n = 3). Two patients (3.6%) were reoperated. The median survival was 38.4 months (CI, 32.8–43.9). Actuarial 2- and 4-year survival rates were 72% and 44%, respectively. The survival rates were not significantly different between patients who had CS + HIPEC for PC alone (including the primary resection) versus those who had associated LMs resection (median survival, 35.3 versus 36.0 months, P = 0.73). Conclusion:Iterative CS + HIPEC is an effective treatment in PC from colorectal cancer. The presence of resectable LMs associated with PC does not contraindicate the prospect of an oncologic treatment in these patients.

Advanced gastric cancer with or without peritoneal carcinomatosis treated with hyperthermic intraperitoneal chemotherapy: a single western center experience.

INTRODUCTION The aim of this article was to evaluate the role of hyperthermic intraperitoneal chemotherapy (HIPEC), associated or not to cytoreductive surgery (CS) in the treatment of different stages of advanced gastric cancer (AGC). PATIENTS AND METHODS Thirty seven patients with AGC who underwent 43 HIPEC from June 1992 to February 2007 were included. HIPEC used Mitomycin-C and Cisplatin for 60-90 min at 41-43 degrees C intra-abdominal temperature. The main endpoints were long-term survivals, morbidity and mortality rates. RESULTS Eleven patients had no demonstrable sign of PC and constituted the Prophylactic-group, while 26 patients had macroscopic PC (PC-group). Five patients were Gilly 1 or 2 (nodules <0.5 cm) and 21 Gilly 3 or 4 (nodules >or=0.5 cm). In the PC-group a complete curative CS was achieved before HIPEC in 8 (PC-curative subgroup) and a palliative HIPEC in 18 patients (PC-palliative subgroup). The overall 30-days mortality was 5% (2 patients). Two patients in the Prophylactic group died within 6 months after hospital discharge (overall mortality 11%). The estimated risk of death per procedure was 9%. Ten patients (27%) presented one or more complications. The median survival was 23.4 months in the Prophylactic group, and 6.6 months in the PC-group (p<0.05). The median survival in the PC-curative subgroup was 15 vs 3.9 months in the PC-palliative subgroup (p=0.007). The median survival according to Gilly classification was significantly different (Gilly 1&2 vs Gilly 3&4, 15 vs 4 months respectively, p=0.014). The global recurrence rates between the Prophylactic group and the PC-curative subgroup at 2years were 36% vs 50% respectively. The median delay to recurrence was 18.5 vs 9.7 months respectively. CONCLUSION HIPEC might be useful to improve the survival in selected patients with ACG only when a complete cytoreduction can be achieved. Despite encouraging data, prospective studies, based on larger cohorts of patients are required to assess the role of this procedure as a prophylactic treatment in patients with AGC.

Risk Factors for Mortality and Morbidity after Elective Sigmoid Resection for Diverticulitis: Prospective Multicenter Multivariate Analysis of 582 Patients

The prevalence of diverticular disease of the colon is increasing in occidental countries. It would be useful to further decrease the mortality and morbidity after elective sigmoid resection (ESR) for diverticulitis. The aim of this study was to identify modifiable preoperative and intraoperative risk factors for mortality and morbidity after ESR for diverticulitis. , A database of 2615 patients who underwent a colon or rectal resection with primary anastomosis between 1985 to 1998 has been constructed from prospective randomized studies published by a French surgical group. Of those patients, 582 had undergone ESR for diverticulitis, and they constitute the population of the present study. A total of 46 potential preoperative and intraoperative risk factors for mortality and morbidity have been studied by univariate and multivariate analysis. The operative mortality for our series was 1.2%, and the overall morbidity was 24.9%. The multivariate analysis revealed two statistically significant independent risk factors of mortality: age > 75 (odds-ratio = 7.9; 95%confidence interval [CI 1.7–36.6]; p = 0.01) and obesity (odds ratio = 5.2; 95%CI [1.1–27.9]; p = 0.04). The abdominal morbidity (AM) was 6.5% (38/582). The absence of antimicrobial prophylaxis administration with ceftriaxone was the only significant risk factor for AM in multivariate analysis (p = 0.003; odds ratio = 2; 95% CI [1.1–4]). The extraabdominal morbidity (EAM) was 18.4% (107/582). Both chronic pulmonary disease (p = 0.008; odds-ratio = 2.9; 95% CI [1.4–6]; p = 0.008) and cirrhosis (odds-ratio = 12; 95% CI [1.2–120]) proved to be significant risk factors for EAM. Weight control prior to surgery, routine administration of prophylactic preoperative antibiotics, and preoperative optimization of the respiratory status of patients with chronic pulmonary disease could decrease the postoperative mortality and morbidity associated with ESR for diverticulitis.

Can laparoscopy reduce hospital stay in the treatment of crohn's disease?

PURPOSE: The aim of this article was to investigate the safety, outcome, length of stay, and cost of hospital admission in patients with Crohns disease who underwent laparoscopy compared with open surgery. METHODS: Among 51 consecutive patients with inflammatory bowel disease (1996–2000), 46 with Crohns disease were included in this nonrandomized prospective study. Of these, 20 patients underwent laparoscopic surgery and 26 underwent open surgery. Data collected included the following information: age, gender, body mass index, diagnosis, duration of disease, preoperative medical treatment, previous abdominal surgery, present indication for surgery, and procedure performed (comparability measures), as well as conversion to open surgery, operating time, time to resolution of ileus, morbidity, duration of hospital stay, and cost of hospital admission (outcome measures). RESULTS: There was no significant difference with respect to comparability measures between the laparoscopic and the open-surgery groups. There was no mortality. There was no intraoperative complication in either group and no conversion in the laparoscopic group. Operating time was significantly longer in the laparoscopic group (302 minutes)vs. the open group (244.7 minutes) (P<0.05), but this difference disappeared when data were adjusted for the extra time required to perform the laparoscopic hand-sewn anastomoses (288.2 minutesvs. 244.7 minutes). Bowel function returned more quickly in the laparoscopic groupvs. the open group in terms of passage of flatus (3.7vs. 4.7 days) (P<0.05) and resumption of oral intake (4.2vs. 6.3 day) (P<0.01). There were significantly fewer postoperative complications in the laparoscopic group (9.5 percent)vs. the open group (18.5 percent) (P<0.05); the length of stay was significantly shorter in the laparoscopic group (8.3 days)vs. the open group (13.2 days) (P<0.01); and the cost of hospital admission was significantly lower in the laparoscopic group (

CONCLUSION: There is a reduction in the postoperative ileus, length of stay, cost of hospital admission, and postoperative complication rate in the laparoscopic group. Laparoscopic surgery for Crohns disease is safe, and it is potentially more cost-effective than traditional open surgery.

Lésions précancéreuses de la vésicule biliaire

PURPOSE: With advances in laparoscopy, various hemostatic procedures have been advocated with variable results. Using currently available tools, some steps in laparoscopic colorectal surgery still represent technical challenges. Our aim was to investigate the feasibility and reliability of the Harmonic Scalpel™ in laparoscopic colorectal surgery. METHODS: In this nonrandomized prospective study, 34 consecutive patients (15 males; mean age, 46 (range, 24–80) years) underwent laparoscopic colorectal surgery for benign disease (27 patients) and colorectal cancer (7 patients). Dissection, hemostasis, coagulation, and division of several types of vascular pedicles were performed exclusively with the Harmonic Scalpel™. The 10-mm-blade Harmonic Scalpel™ device was used at full power mode for all purposes through a 10-mm port. Coagulation of vascular pedicles was always achieved with the blades in the flat position. The large pedicles (inferior mesenteric, right and left colic, and ileocolic) were coagulated for 20 seconds in several locations along the length (1 cm) before final division. Smaller vascular pedicles were coagulated for ten seconds before division. When the vein and the artery of major pedicles were divided at their origin, either for malignancy or for technical reasons, they were dissected and coagulated separately. For more limited resection of the mesentery, as in the case of benign disease, vascular pedicles were coagulated together as a single bundle. Operative time, minor or major intraoperative or postoperative hemorrhage, need for conversion to laparotomy, bowel injury, and trocar complications were recorded. All anastomoses were checked on Day 8 by a diatrizoate sodium enema. RESULTS: There was no mortality. Mean operative time was 276 (range, 200–520) minutes. Neither minor nor uncontrollable hemorrhage occurred; no conversion to laparotomy and no vascular or bowel injury were recorded. There was one port-site hematoma. Neither hemoperitoneum, intraperitoneal hematoma, fistula, nor intra-abdominal abscess was observed. CONCLUSION: Coagulation and division of minor as well as major vascular pedicles in laparoscopic colorectal surgery with the Harmonic Scalpel™ are technically easy, feasible, and reliable.

Surgeon-dependent predictive factors for mortality after elective colorectal resection and immediate anastomosis for cancer or nonacute diverticular disease: multivariable analysis of 2,605 patients.

PURPOSE Desmoplastic round small cell tumor (DRSCT) is a rare intraabdominal mesenchymal tissue neoplasm in young patients and spreads through the abdominal cavity. Its prognosis is poor despite a multimodal therapy including chemotherapy, radiotherapy, and surgical cytoreduction (CS). hyperthermic intraperitoneal chemotherapy (HIPEC) is considered as an additional strategy in the treatment of peritoneal carcinomatosis; for this reason, we planned to treat selected cases of children with DRSCT using CS and HIPEC. METHODS Peritoneal disease extension was evaluated according to Gilly classification. Surgical cytoreduction was considered as completeness of cytoreduction-0 when no macroscopic nodule was residual; HIPEC was performed according to the open technique. RESULTS We described 3 cases: the 2 first cases were realized for palliative conditions and the last one was operated on with curative intent. There was no postoperative mortality. One patient was reoperated for a gallbladder perforation. There was no other complication related to HIPEC procedure. CONCLUSIONS Surgical cytoreduction and HIPEC provide a local alternative approach to systemic chemotherapy in the control of microscopic peritoneal disease in DRSCT, with an acceptable morbidity, and may be considered as a potential beneficial adjuvant waiting for a more specific targeted therapy against the fusion protein.

Syndrome fissuraire d'un pseudoanévrisme de l'artère gastroduodénale au contact d'un faux-kyste pancréatique : une complication rare mais grave de la pancréatite chronique

This Mini-review summarizes the epidemiology, predisposing and pre-cancerous conditions related to carcinoma of the gallbladder. In 75% of cases, gallbladder cancer is a cholangiocarcinoma, usually presenting in a late and advanced stage, and it carries one of the worst prognoses of all GI malignancies. Early stage disease is usually discovered incidentally by the pathologist in a gallbladder specimen removed for calculous cholecystitis. It occurs three times more frequently in women than in men and invasive forms usually occur after the age of 60. Incidence varies with geographic location. Besides genetic and geographic factors, the presence of one or more large gallstones is a major risk factor. Gallbladder polyps larger than 1.5 cm. (especially solitary sessile hypoechogenic polyps) are associated with a 50% risk of malignancy. Choledochal cysts and other variations of the biliopancreatic junction are also associated with high risk; cancer may occur at a much younger age in these patients and in the absence of gallstones. Porcelain gallbladder is a risk factor, particularly when there is calcification of the gallbladder mucosa. Chronic gallbladder infection has been implicated as a risk factor for malignant degeneration. Finally, cancer of both the gallbladder and the bile ducts is more frequent in patients suffering from primary biliary cirrhosis.
