Randomized clinical trial of intestinal ostomy takedown comparing pursestring wound closure vs conventional closure to eliminate the risk of wound infection.

BACKGROUND: The use of temporary stomas has been demonstrated to reduce septic complications, especially in high-risk anastomosis; therefore, it is necessary to reduce the number of complications secondary to ostomy takedowns, namely wound infection, anastomotic leaks, and intestinal obstruction. OBJECTIVE: To compare the rates of superficial wound infection and patient satisfaction after pursestring closure of ostomy wound vs conventional linear closure. DESIGN: Patients undergoing colostomy or ileostomy closure between January 2010 and February 2011 were randomly assigned to linear closure (n = 30) or pursestring closure (n = 31) of their ostomy wound. Wound infection within 30 days of surgery was defined as the presence of purulent discharge, pain, erythema, warmth, or positive culture for bacteria. Patient satisfaction, healing time, difficulty managing the wound, and limitation of activities were analyzed with the Likert questionnaire. RESULTS: The infection rate for the control group was 36.6% (n = 11) vs 0% in the pursestring closure group (p < 0.0001). Healing time was 5.9 weeks in the linear closure group and 3.8 weeks in the pursestring group (p = 0.0002). Seventy percent of the patients with pursestring closure were very satisfied in comparison with 20% in the other group (p = 0.0001). LIMITATIONS: This study was limited by the heterogeneity in the type of stoma in both groups. CONCLUSION: The pursestring method resulted in the absence of infection after ostomy wound closure (shorter healing time and improved patient satisfaction).

Laparoscopic versus open total mesorectal excision: a nonrandomized comparative prospective trial in a tertiary center in Mexico City.

Because definitive long-term results are not yet available, the oncologic safety of laparoscopic surgery in rectal cancer remains controversial. Laparoscopic total mesorectal excision (LTME) for rectal cancer has been proposed to have several short-term advantages in comparison with open total mesorectal excision (OTME). However, few prospective randomized studies have been performed. The main purpose of our study was to evaluate whether relevant differences in safety and efficacy exist after elective LTME for the treatment of rectal cancer compared with OTME in a tertiary referral medical center. This comparative nonrandomized prospective study analyzes data in 56 patients with middle and lower rectal cancer treated with low anterior resection or abdominoperineal resection from November 2005 to November 2007. Follow-up was determined through office charts or direct patient contact. Statistical analysis was performed using chi2 test and Student's t test. Twenty-eight patients underwent LTME and 28 patients were in the OTME group. No conversion was required in the LTME group. Mean operating time was shorter in the laparoscopic group (LTME) (181.3 vs 206.1 min, P < 0.002). Less intraoperative blood loss and fewer postoperative complications were seen in the LTME group. Return of bowel motility was observed earlier after laparoscopic surgery. There was no 30-day mortality and the overall morbidity was 17 per cent in the LTME group versus 32 per cent in the OTME group. The mean number of harvested lymph nodes was greater in the laparoscopic group than in the OTME group (12.1 +/- 2 vs 9.3 +/- 3). Mean follow-up time was 12 months (range 9-24 months). No local recurrence was found. LTME is a feasible procedure with acceptable postoperative morbidity and low mortality, however it is technically demanding. This series confirms its safety, although oncologic results are at present comparable with the OTME published series with the limitation of a short followup period. Further randomized studies are necessary to evaluate long-term clinical outcome.

[Open vs. laparoscopic loop ileostomy clousure after colorectal surgery: retrospective analysis]. / Análisis del cierre de ileostomía en asa subsecuente a cirugía colorrectal laparoscópica vs. abierta.

INTRODUCTION: A protective loop ileostomy for a distal anastomosis of the rectum or anus, decreases the risk of sepsis secondary to anastomotic leak or dehiscence. This study examines whether the surgical technique employed in the construction of the anastomosis (open vs. laparoscopic) alters the subsequent closure of ileostomy. OBJECTIVE: The goal of this study is to determine whether at the time of a protective ileostomy closure, the fact of doing an initial laparoscopic surgery has advantages over those who underwent open surgery. MATERIAL AND METHODS: This is a comparative and retrospective analysis of the results of an ileostomy closure with prior open surgery (ICPOS) vs those performed with a prior laparoscopic surgery (ICPLS). Demographic and surgical results were analyzed. Fisher's test and Chi square tests were used. A statistically significant results was defined as p < 0.05. RESULTS: A total of 71 patients were included: 42 (59.2%) ICPOS and 29 (40.8%) ICPLS. Surgical time and hospital stay were less in the ICPLS group when compared with the ICPOS group. 79 vs. 133 min (p = 0.0001) and 3 vs. 5 days (p = 0.0001). Four patients (66.7%) from the ICPOS group developed ileum, whereas only 2 (33.3% from the ICPLS presented it (p = 0.04). Six patients had surgical wound infection, 5 (83.3%) of them represented the ICPOS group and only 1 (16.7%) represented the ICPLS group (p = 0.01). Four patients (5.6%) had anastomotic dehiscence, all of them were from the ICPOS group (p = 0.0037). On the ICPOS group 6 patients were reinterveined after the ileostomy closure, whereas none from the ICPLS required it (p = 0.01). CONCLUSIONS: An ICPLS seems to have advantages over a ICPOS when analyzing surgical time, hospital stay and surgical ileum development, a lesser infection rate and a lesser re intervention rate at last.

Laparoscopic vs. open total mesorectal excision for treatment of rectal cancer.

INTRODUCTION: Because definitive long-term results are not yet available, the oncologic safety of laparoscopic surgery in rectal cancer remains controversial. Laparoscopic total mesorectal excision (LTME) for rectal cancer has been proposed to have several short-term advantages in comparison with open total mesorectal excision (OTME). However, few prospective randomized studies have been performed. OBJECTIVES: The main purpose was to evaluate whether there are relevant differences in safety and efficacy after elective LTME for the treatment of rectal cancer compared with OTME in a tertiary academic medical center. MATERIAL AND METHODS: This comparative non-randomized prospective study analyzes data of 20 patients with middle and low rectal cancer treated with low anterior resection (LAR) or abdomino perineal resection (APR) from November 2005 to April 2006. Follow-up was determined through office charts or direct patient contact. Statistical analysis was performed using chi2 test and Student's t-test. RESULTS: Ten patients underwent LTME and 10 patients underwent OTME. No conversion was required in the LTME group. Mean operating time was shorter in the laparoscopic group (LTME) (186.7 vs. 204.4 min, p < 0.007). Less intraoperative blood loss and fewer postoperative complications were seen in the LTME group. An earlier return of bowel motility was achieved after laparoscopic surgery. There was no 30-day mortality and the overall morbidity was 20% in the LTME group vs. 40% in the OTME group. The mean number of harvested lymph nodes was greater in the laparoscopic group than in OTME group (10.2 +/- 2.5 vs. 8.3 +/- 3). Mean follow-up time was 12 months (range 9-15 months). No local recurrence was found. CONCLUSION: LTME is a feasible procedure with acceptable postoperative morbidity and low mortality, however it is technically demanding. This series confirms its safety, while oncologic results are at present comparable to the OTME published series, with limitation of a short follow-up period though. Further randomized studies are necessary to evaluate long-term clinical outcome.

Primary colonic lymphoma.

Surgical resection of primary colonic lymphoma can be an important therapeutic tool. We performed a nonrandomized retrospective descriptive study at the University hospital tertiary care center. From January 1990 to June 2002, a total of 15 patients with primary colonic lymphoma were identified from the tumor registry at University of Alabama at Birmingham and retrospectively reviewed under Institutional Review Board approved protocol. Demographic data, clinical features, treatment method (surgery and/or chemotherapy), recurrence rate, and survival were analyzed. The results are presented as mean +/- standard deviation or median and range. Differences in survival were evaluated by the log-rank test and the interval of disease-free survival was calculated using the Kaplan-Meier method. A P value of <0.05 was considered statistically significant. Main outcome measures included surgical results, morbidity, mortality, and recurrence rate. Mean age was 51.5 years (standard deviation 16.4), 33 per cent were male and 67 per cent were female. Presenting symptoms were diarrhea (53.5%), lower gastrointestinal bleeding (13.3%), and nausea and vomiting (46.7%) secondary to low-grade obstruction. Concomitant colorectal disease was present in one patient with ulcerative colitis. Preoperative diagnosis of lymphoma was made in 13 patients (87%) with colonoscopy and biopsy. CT scan was performed in all patients; and none had radiographic evidence of systemic extension. Only one patient had a history of lymphoproliferative disease and exposure to radiation. The most common disease location was the cecum (60%), followed by the right colon (27%), and the sigmoid colon (13%). The mean lactic dehydrogenase (LDH) value was 214.9 u/L (range 129-309). Thirty-three per cent of the patients had an LDH value that was above the upper normal limit. LDH returned to normal after treatment in all patients. Operations performed consisted of right hemicolectomy (13), total proctocolectomy with ileal J J-pouch (1), and sigmoid colectomy (1). Eighty-seven per cent had negative margins at the time of operation. Twelve patients received postoperative chemotherapy (80%). According to the clinical classification of primary non-Hodgkin lymphoma (NHL) of the gastrointestinal tract (Lugano, 1993) all patients corresponded to stage IE. Mean hospital stay was 6.4 days (range 3-26). There was no surgical mortality and the morbidity rate was 20 per cent (3 patients). One patient had a systemic recurrence (7%) approximately 4 months after surgical resection. Mean follow-up was 31 months (median 2-73). Surgical resection of localized, primary colonic lymphoma provides excellent local disease control and should be considered a primary treatment option. The role of chemotherapy remains controversial depending on the grade, stage, and extension of residual disease.

[Surgical treatment for colonic diverticular disease. Experience in the INCMNSZ]. / Tratamiento quirúrgico para la enfermedad diverticular de colon. Experiencia en el INCMNSZ.

BACKGROUND: Even though most patients with colonic diverticular disease respond to conservative management, some patients persist with symptoms or develop complications that require surgery. The objective of this study was to identify main surgical indications for colonic diverticular disease, and to evaluate the outcomes of surgical treatment. MATERIALS AND METHODS: A retrospective review of patients that underwent a surgical procedure for colonic diverticular disease from 1979 through 2000, was performed. Surgical indications were acute diverticulitis (54%) (group 1), stenosis (19%), fistula (9.54), recurrent diverticulitis (9.5%) and bleeding (8%) (group 2). Results. Seventy-four patients with a mean age of 56 years were studied. Fifty-eight percent were male. Surgical morbidity and mortality rates of acute diverticulitis were 55%, and 15%, respectively. The surgical procedures of this group were proximal stomas (45%), Hartmann's procedures (38%), and resections with primary anastomosis (17%). Second group morbidity and mortality rates were 35 and 5.8%, respectively. Thirty-six patients underwent two or more surgical procedures with statistical significance between first and second groups (61 vs. 28%; p < 0.05). The mortality of two-stage surgeries was lower than derivative procedures (13 vs. 22%; p = 0.009). A high Hinchey's score was the only factor associated with mortality (28.5 vs. 0%; p = 0.042). CONCLUSIONS: Mortality of surgical procedures for colonic diverticular disease is associated with a high Hinchey score. Primary anastomosis is o safe, procedure in some cases.

Antecedentes. Aunque la mayoría de pacientes con enfermedad diverticular de colon responde al manejo conservador, algunos persisten con síntomas o presentan complicaciones que requieren cirugía. El objetivo de esta revisión fue identificar las indicaciones quirúrgicas para la enfermedad diverticular de colon y evaluar los resultados en el manejo quirúrgico de la misma. Material y métodos. Se realizó una revisión retrospectiva de pacientes sometidos a cirugía por enfermedad diverticular de colon de 1979 al 2000. Las indicaciones de cirugía fueron diverticulitis aguda (54%) (grupo 1), estenosis (19%), fístula (9.5%), diverticulitis recurrente (9.5%) y hemorragia (8%) (grupo 2). Resultados. Se estudiaron un total de 74 pacientes con una edad promedio de 56 años. Cincuenta y ocho por ciento fueron del sexo masculino. La morbilidad de los pacientes operados por diverticulitis aguda fue de 55% y la mortalidad de 15%. El tipo de cirugías en este grupo fueron estomas derivativos (45%), procedimientos de Hartmann (38%) y resecciones con anastomosis primaria (17%). La morbilidad y la mortalidad de las cirugías del segundo grupo fueron de 35 y 5.8%, respectivamente. Treinta y seis pacientes tuvieron dos o más operaciones, con diferencia significativa al comparar el grupo 1 con el grupo 2 (61 vs. 28%; p < 0.05). La mortalidad de los pacientes que tuvieron un procedimiento resectivo fue menor que cuando se desfuncionalizó (13 vs. 22%; p - 0.009). El único factor asociado con mortalidad fue un Hinchey elevado (28.5 vs. 0%; p - 0.042). Conclusiones. La mortalidad de la cirugía para complicaciones de la enfermedad diverticular de colon se asocia a un grado de Hinchey elevado. La resección con anastomosis primaria es un procedimiento seguro en casos seleccionados.

Molgramostim (GM-CSF) associated with antibiotic treatment in nontraumatic abdominal sepsis: a randomized, double-blind, placebo-controlled clinical trial.

HYPOTHESIS: The addition of molgramostim (recombinant human granulocyte-macrophage colony-stimulating factor) to antibiotic therapy for nontraumatic and generalized abdominal sepsis is effective and has a significant impact on length of hospitalization, direct medical costs, and mortality. DESIGN: Randomized, double-blind, placebo-controlled clinical trial. SETTING: Tertiary referral center. PATIENTS: Fifty-eight patients with abdominal sepsis. INTERVENTIONS: Patients were allocated to receive, in addition to ceftriaxone sodium, amikacin sulfate, and metronidazole, molgramostim in a daily dosage of 3 microg/kg for 4 days (group 1) or placebo (group 2). Antibiotics were administered for at least 5 days and discontinued after clinical improvement had occurred and white blood cell count had been normal for 48 hours. MAIN OUTCOME MEASURES: Time to improvement, duration of antibiotic therapy, hospital stay, complications, mortality, and adverse reactions to drugs. RESULTS: Median time to improvement was 2 days in group 1 and 4 days in group 2 (P<.005). Median length of hospitalization was 9 and 13 days, respectively (P<.001), and median duration of antibiotic therapy was 9 and 13 days, respectively (P<.001). Numbers of infectious complications in the 2 groups were, respectively, 6 and 16 (P = .02); of residual abscesses, 3 and 5; and of deaths, 2 and 2. Costs per patient were 12,333 dollars and 16,081 dollars (US dollars), respectively. CONCLUSION: Addition of molgramostim to antibiotic therapy reduces the rate of infectious complications, the length of hospitalization, and costs in patients with nontraumatic abdominal sepsis.

Complete resection of choledochal cyst with Roux-en-Y derivation vs. cyst-enterostomy as standard treatment of cystic disease of the biliary tract in the adult patient.

BACKGROUND/AIMS: Cystic disease of the biliary tract (CDBT) is characterized by varying degrees of dilatation of the biliary system with high morbidity and mortality in which the surgical management is the corner stone of treatment. The cyst-enterostomies (CE) temporarily solve the obstruction to the biliary flow but have a high long-term morbidity. Complete resection of affected bile ducts with Roux-en-Y derivation (CRR-en-Y) is a good procedure with low mortality and complications. The purpose of the study was to analyze the outcome of CRR-en-Y versus CE in the treatment of CDBS in adult patients from 1970 to 2002. METHODOLOGY: Patients who underwent surgical treatment were divided for their analysis into two groups: Group I: CRR-en-Y and Group II: CE. Following features were compared: demography, clinical picture, postoperative morbimortality, outcome and survival. RESULTS: Thirty-four adult patients were analyzed. There were 82% (28) females and 18% (6) males. The age average was 33.58 years (13-84). Seventy percent (30) were "choledochal cyst". Eighty percent (27) were surgically handled: 52% (14) with CRR-en-Y (Group I) versus 58% (13) with CE (Group II). Both groups were comparable. Without operative mortality and low postoperative morbidity in both, CE had more long-term complications: In this group 70% (9) were readmitted: and 7 underwent reoperation. Mean follow-up was 35 months (6-132) versus 152 months (12-408) respectively. CONCLUSIONS: CRR-en-Y is the standard treatment of CDBS in the adult patient.

Hormonal changes after Roux-en Y gastric bypass for morbid obesity and the control of type-II diabetes mellitus.

Morbid obesity (MO) is associated with diabetes mellitus-type II (DM-II). Roux-en Y gastric bypass (RNY) has been shown to normalize glucose intolerance in these patients through an incompletely understood mechanism. Gastrointestinal hormonal changes have been suggested as an explanation for resolution of DM II. Preoperatively, 20 MO patients with DM-II were evaluated for demographics and fasting levels of the following: glucose, insulin, C-peptide, glucagon, cortisol, gastric inhibitory polypeptide (GIP), and glucagon-like peptide-1 (GLP-1). Each patient underwent RNY with a 15-cc gastric pouch and 150-cm Roux limb. Postoperatively, each of the variables was measured at 2 weeks, 6 weeks, and 12 weeks and compared with the preoperative result using Student t test with significance, P = 0.05. Results are expressed as mean +/- SD. Twenty patients (5 male and 15 female), age 40.3 +/- 7.9 years, weight 146.3 +/- 34.0 kg, height 158.7 +/- 18.7 cm, and BMI 52.7 +/- 8.8, were enrolled in this IRB-approved protocol. Weight and BMI decreased progressively (117.5 +/- 26.9 kg and 47.0 +/- 7.4, P = 0.01, respectively) during the study but reached significance only at 12 weeks. Fasting plasma glucose decreased significantly within 2 weeks after RNY. Insulin and cortisol both approached, but never achieved, significant changes over 12 weeks. GLP-1 increased initially, but not significantly. GIP and C-peptide both decreased significantly. Glucagon remained essentially unchanged over 12 weeks. RNY rapidly normalizes fasting plasma glucose in morbidly obese patients with DM-II. GIP, a gactor in the enteroinsulin axis, decreases and may play a role in the correction of DM-II after gastric bypass.

Serum lactic acid determines the outcomes of CT diagnosis of pneumatosis of the gastrointestinal tract.

Computed tomography (CT) diagnosis of pneumatosis involving the gastrointestinal tract can represent a broad range of clinical entities from a benign process to ischemic bowel. The purpose of this study is to define the significance and outcome of pneumatosis intestinalis (PI). All CT scans from 5/93 to 12/01 with the finding of PI were reviewed. Eighty-six CT scans had the finding of PI, with the colon being the most frequent location (51%), followed by small bowel (36%) and gastric (9%). Forty per cent of patients underwent surgery, with an overall mortality rate of 42 per cent and a surgical mortality rate of 47 per cent. Univariate analysis demonstrated significant correlation between serum lactic acid (LA) > 2.0 mmol/L [odds ratio (OR) = 23.4; 95% confidence interval (C.I.), 7.21-75.92] and serum creatinine > 1.5 mg/dL (OR = 3.05; 95% C.I., 1.25-7.42) with mortality. Age was suggestive but not a significant risk factor for mortality (P = 0.09). Multivariate analysis found serum LA > 2.0 (OR = 30.37; 95% C.I., 7.31-126.2) to be the only significant predictor of mortality. CT diagnosis of PI is associated with significant in-hospital mortality, especially in the elderly. Serum LA level > 2.0 mmol/L at time of diagnosis is associated with a greater than 80 per cent mortality. Surgical consultation is necessary to determine which patients need urgent surgical intervention.

[Cystic disease of the biliary tract. Three decades of institutional experence]. / Enfermedad quística de la vía biliar en el adulto. Tres décadas de experiencia institucional.

INTRODUCTION: Cystic disease of biliary tract (CDBT) characterizes by the presence of sacular expansions of the biliary tree. It is an uncommon disease associated with high morbidity and malignant transformation. More than 60% of patients are women and can be diagnosed in the adult life. OBJECTIVE: To evaluate the results obtained during last three decades in the management of CDBT in the adult patient. PATIENTS AND METHODS: All the patients with CDBT treated from 1970 to 2002 were included. Demographic data, clinical picture, boarding diagnosis, classification, treatment, evolution and survival were analyzed. RESULTS: 34 patients. Twenty eight (82%) women and 6 (18%) men with a mean age of 33 years (range 13-84). The most frequent symptoms were abdominal pain, nausea-vomit and jaundice. Cholangiography was made in all cases. All the types described by Todani were documented. Twenty-seven patients (80%) were surgically treated. The mean follow-up was 84 months (range 1-408 months). Fifteen patients (44.1%) were readmitted and 9 (26.4%) had a reoperation. Three (9%) died with malignant transformation. The global survival was 91.1% to 12 months. CONCLUSIONS: In the adult patient, diagnosis of CDBT requires a high level of suspicion and its confirmation depends on the image studies. The CDBT diagnosis considers an indication of surgical treatment. Complete resection of the biliary tract with Roux en-Y hepato-jejunal anastomosis have less rate of mechanical complications, hospitalary readmissions and surgical reintervention.

Gastrointestinal symptomatic outcome after laparoscopic Roux-en-Y gastric bypass.

Laparoscopic Roux-en-Y (RY) gastric bypass is an effective treatment for morbid obesity. However, little information is available regarding the gastrointestinal symptomatic outcome after laparoscopic RY gastric bypass for morbid obesity. The purpose of this study is to identify changes occurring in gastrointestinal symptoms after laparoscopic RY gastric bypass. A previously validated, 19-point gastrointestinal symptom questionnaire was administered prospectively to each patient seen for surgical consultation to treat morbid obesity. Patients rated the degree to which each symptom affected their lives on a 0 to 100 mm Liekert scale with 0 indicating absence of a symptom, 33 indicating the symptom was present occasionally, 67 indicating the symptom occurred frequently, and 100 indicating the symptom was continuous. The same survey was readministered 6 months postoperatively. The mean of each symptom (preoperative vs. postoperative value) was compared using Student's t test with significance at P<0.05. Forty-three preoperative patients (age 37.3+/-8.6 years; body mass index 47.8+/-4.9) and thirty-five, 6 months' postoperative patients (81% follow-up; body mass index 31.6+/-5.3) completed the questionnaire. The result for each symptom is expressed as mean+/-standard deviation of preoperative vs. postoperative scores. Significantly different symptoms include the following: abdominal pain 23.3+/-26.4 vs. 8.6+/-13.5, P=0.003; heartburn 34.0+/-26.6 vs. 8.0+/-14.0, P=0.0001; acid regurgitation 28.1+/-24.0 vs. 10.7+/-21.0, P=0.001; gnawing in epigastrium 19.3+/-22.7 vs. 7.5+/-16.0, P=0.01; abdominal distention 38.2+/-31.5 vs. 11.1+/-19.2, P=0.0001; eructation 27.7+/-24.4 vs. 15.5+/-16.9, P=0.01; increased flatus 40.2+/-25.7 vs. 25.2+/-25.3, P=0.005; decreased stools 5.4+/-16.8 vs. 17.4+/-20.0, P=0.0005; increased stools 23.9+/-26.7 vs. 6.5+/-11.7, P=0.0005; loose stools 29.7+/-26.5 vs. 17.5+/-20.0, P=0.03; urgent defecation 34.3+/-26.5 vs. 14.3+/-19.3, P=0.0009; difficulty falling asleep 44.1+/-38.4 vs. 27.5+/-32.9, P=0.05; insomnia 42.4+/-36.2 vs. 21.6+/-30.5, P=0.008; and rested on awakening 65.1+/-33.8 vs. 30.5+/-28.8, P=0.0001. Symptoms that did not significantly change included the following: nausea/vomiting 17.2+/-22.7 vs. 22.1+/-19.9, P=0.33; borborygmus 28.8+/-25.2 vs. 26.8+/-29.7, P=0.75; hard stools 10.3+/-22.9 vs. 7.1+/-18.6, P=0.56; incomplete evacuation of stool 17.2+/-22.8 vs. 13.4+/-21.7, P=0.45; and dysphagia 10.9+/-15.6 vs. 17.7+/-28.4, P=0.18. Laparoscopic RY gastric bypass significantly improves many gastrointestinal symptoms experienced by morbidly obese patients without adversely affecting any of the measured parameters. This information is useful in preoperative counseling to assure patients of overall symptomatic improvement after this operation in addition to significant weight loss and improvement of comorbid conditions.

Results of long-term follow-up for transanal excision for rectal cancer.

Low anterior resection and abdominoperineal resection are the surgical techniques used most frequently in the treatment of rectal cancer. It is our hypothesis that selected patients with early T stage, well or moderate grade of differentiation, and small tumor size are good candidates for transanal excision in terms of minimal morbidity, low recurrence rate, and sphincter preservation. From January 1993 until August 2001 30 patients underwent transanal excision; three patients were excluded because they had histology other than adenocarcinoma. Factors analyzed included those related to the patient [age (years), gender, race, body mass index, and anal tone], tumor [size (cm), distance from the anal verge (cm), differentiation, and American Joint Committee on Cancer stage], and additional treatment. Median follow-up of the group was 40.7 months (range 0.6-99) and the primary end points were local and distant recurrence. Data are presented as mean (range). The median age of the group was 58.9 years (range 27-94); 52 per cent were female and 48 per cent were male. The mean body mass index was 25.9 (range 22.7-36.7). Preoperatively 81, 11, and 4 per cent of the patients had stage I, II, and III/IV cancer, respectively. Preoperative size of the tumor was 2.0 cm (1-3 cm), and distance from the anal verge was 5.0 cm (3-15 cm). Blood loss was 50 cm3 (5-200 cm3), and there were no operative complications. Tumor differentiation levels were well (37%) and moderate (63%). All patients had negative margins. Additional treatment consisted of radiation therapy in seven patients (six postoperative and one preoperative). Chemotherapy was given to seven patients (six postoperative and one preoperative). The local recurrence rate was 7.4 per cent (two patients), and 3.7 per cent recurred distantly (one patient). Transanal excision of low rectal cancer in selected patients is an acceptable alternative to formal resection. Important selection criteria include early T stage, well or moderate differentiation, relatively small tumor size, and negative microscopic margins. The roles of radiation and chemotherapy remain controversial.

Gastrointestinal symptoms are more intense in morbidly obese patients and are improved with laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: Currently there are few reports comparing gastrointestinal (GI) symptoms in the morbidly obese versus control subjects or the effect of laparoscopic Roux-en-Y gastric bypass (LRYGBP) on such symptoms. METHODS: A previously validated, 19-point GI symptom questionnaire was administered prospectively to each patient undergoing LRYGBP, and the questionnaire was re-administered 6 months postoperatively. Six symptom clusters (abdominal pain, irritable bowel [IBS], reflux, gastroesophageal reflux disease [GERD], sleep disturbances, and dysphagia) were compared in the following manner using Students t-test: 1) Control vs. Preop, 2) Control vs Postop, and 3) Preop vs Postop. Results are expressed as mean +/- standard deviation, significance P=0.05. RESULTS: 43 patients (40 female and 3 male, age 37.3 +/- 8.6, BMI 47.8 +/- 4.9) completed the questionnaire preoperatively, and 36 patients (34 female, 2 male, BMI 31.6 +/- 5.3) completed the questionnaire 6 months postoperatively, for a response-rate of 84%. Abdominal pain, IBS, reflux, GERD and sleep disturbance symptoms were significantly worse in preop versus controls. Dysphagia was not different. Postop vs preop scores revealed abdominal pain, IBS, GERD, reflux, and sleep disturbance symptoms to be improved significantly. Dysphagia was not significantly different. Only dysphagia was worse when comparing postoperative to controls. No other symptom cluster was significantly different in controls vs postoperative. CONCLUSIONS: Morbidly obese patients experience more intense GI symptoms than control subjects, and many of these symptoms return to control levels 6 months after LRYGBP. Dysphagia is equivalent to control subjects preoperatively but increases significantly after LRYGBP. This data suggests another quality-of-life improvement (relief of GI symptoms) for morbidly obese patients. Further follow-up is needed to document the long-term reduction of GI symptoms.

Laparoscopic vs conventional ileocolectomy for primary Crohn disease.

HYPOTHESIS: Laparoscopic ileocolectomy can reduce the length of hospital stay and hospital charges compared with conventional surgery in the treatment of primary Crohn disease. DESIGN: Nonrandomized, comparative, retrospective analysis of a prospective database. SETTING: University hospital tertiary care center for inflammatory bowel disease. PATIENTS: Forty patients, 20 in the laparoscopic group (group A) and 20 in the conventional group (group B). INTERVENTION: From July 1, 1996, to June 30, 2001, we collected data on the following demographic clinical end points: age, sex, duration of disease, preoperative medical treatment, previous abdominal surgery, procedure performed, conversions to open surgery, operating time, number of trocars used, size of incision, blood loss, time to resolution of ileus, time to starting solid food diet, duration of hospital stay, hospital charges, morbidity, and mortality. MAIN OUTCOME MEASURES: Surgical results, length of hospital stay, hospital charges, and recurrences. RESULTS: The mean age of the patients was 34.7 years (range, 20-68 years) in group A vs 40.0 years (range, 18-75 years) in group B. The male-female ratio was 1:2 in group A vs 1:1 in group B. The morbidity was 5% in group B. There was no mortality. Operating time was longer in group A (mean, 145.0 minutes; range, 45-270 minutes) compared with group B (mean, 133.5 minutes; range, 98-177 minutes) (P =.36). Blood loss was significantly higher in group B (mean, 265.5 mL; range, 100-400 mL) compared with group A (77.2 mL; range, 25-350 mL) (P<.001). Also, the size of the incision was significantly longer in group B (mean, 13.5 cm; range, 8-18 cm) compared with group A (mean, 5.5 cm; range, 3-12 cm) (P<.001). Bowel function returned more quickly in the laparoscopic group vs the conventional group in terms of return of bowel movements (1.70 vs 2.63 days) (P<.001) and resumption of a regular diet (1.35 vs 2.73 days) (P<.001). The mean length of stay was significantly shorter in the laparoscopic group (4.25 days) vs the conventional group (8.25 days) (P<.001). The mean hospital charges were US $9614 in group A vs US $17 079 in group B (P<.05). The mean follow-up was 17.2 months in group A (range, 2.3-59.9 months) vs 18.7 months in group B (range, 1.0-37.5 months). CONCLUSIONS: Laparoscopic-assisted ileocolectomy for primary Crohn disease of the terminal ileum and/or cecum is safe and successful in most cases. Laparoscopic surgery for Crohn disease should be considered as the preferred operative approach for primary resections.

Melanoma en la confluencia de los conductos hepáticos. Reporte de un caso y revisión de la literatura / Melanoma in the confluence of the hepatic ducts. Report of a case and review of the literature

El melanoma primario de los conductos biliares es una entidad extremadamente rara, habiéndose reportado en la literatura solamente siete casos previamente. En el presente manuscrito se reporta el caso de una paciente de 67 años de edad con un melanoma primario en la confluencia de los conductos hepáticos. La paciente fue sometida a resección y hepático-yeyuno anastomosis. Al último seguimiento, la paciente se encontraba sin evidencia de enfermedad tumoral (17 años después de la resección). Se realizó una revisión extensa de la literatura y se concluyó que la resección quirúrgica ofrece la posibilidad de supervivencia a largo plazo.
