Transanal total mesorectal excision for rectal cancer has been suspended in Norway.

BACKGROUND: Transanal total mesorectal excision (TaTME) for rectal cancer has emerged as an alternative to the traditional abdominal approach. However, concerns have been raised about local recurrence. The aim of this study was to evaluate local recurrence after TaTME. Secondary aims included postoperative mortality, anastomotic leak and stoma rates. METHODS: Data on all patients who underwent TaTME were recorded and compared with those from national cohorts in the Norwegian Colorectal Cancer Registry (NCCR) and the Norwegian Registry for Gastrointestinal Surgery (NoRGast). Kaplan-Meier estimates were used to compare local recurrence. RESULTS: In Norway, 157 patients underwent TaTME for rectal cancer between October 2014 and October 2018. Three of seven hospitals abandoned TaTME after a total of five procedures. The local recurrence rate was 12 of 157 (7·6 per cent); eight local recurrences were multifocal or extensive. The estimated local recurrence rate at 2·4 years was 11·6 (95 per cent c.i. 6·6 to 19·9) per cent after TaTME compared with 2·4 (1·4 to 4·3) per cent in the NCCR (P < 0·001). The adjusted hazard ratio was 6·71 (95 per cent c.i. 2·94 to 15·32). Anastomotic leaks resulting in reoperation occurred in 8·4 per cent of patients in the TaTME cohort compared with 4·5 per cent in NoRGast (P = 0·047). Fifty-six patients (35·7 per cent) had a stoma at latest follow-up; 39 (24·8 per cent) were permanent. CONCLUSION: Anastomotic leak rates after TaTME were higher than national rates; local recurrence rates and growth patterns were unfavourable.

ANTECEDENTES: La resección total del mesorrecto transanal (transanal total mesorectal excision, TaTME) para el cáncer de recto se ha propuesto como una alternativa al abordaje abdominal tradicional. Sin embargo, la recidiva local (local recurrence, LR) después de este procedimiento es motivo de preocupación. El objetivo de este estudio fue evaluar la LR en pacientes operados mediante TaTME. Los objetivos secundarios incluyeron la mortalidad postoperatoria, las fugas anastomóticas y el porcentaje de estomas. MÉTODOS: Se registraron los datos de todos los pacientes operados mediante TaTME y se compararon con las cohortes nacionales del Registro Noruego de Cáncer Colorrectal (Norwegian Colorectal Cancer Registry, NCCR) y del Registro Noruego de Cirugía Gastrointestinal (Norwegian Registry for Gastrointestinal Surgery, NoRGast) utilizando estimaciones de Kaplan-Meier y la prueba de log-rank para comparar curvas de LR. RESULTADOS: En Noruega, 157 pacientes se sometieron a TaTME por cáncer de recto entre octubre de 2014 y octubre de 2018. Tres de siete hospitales abandonaron el TaTME después de un total de cinco procedimientos. La LR observada fue 12/157 (7,6%), siendo ocho de ellas multifocales o extensas. La tasa estimada de LR a 2,4 años fue de 11,6 % (i.c. del 95% 6,6 a 19,9) versus 2,4 % (1,4 a 4,3) en el NCCR (log rank P < 0,001). El cociente de riesgos instantáneos (hazard ratio, HR) ajustado fue 6,7 (i.c. del 95% 2,9 a 15,3). Las fugas anastomóticas que precisaron una reintervención después de TaTME ocurrieron en un 8,4% versus 4,5% en el registro NoRGast (P = 0,047). Cincuenta y seis pacientes (35,7%) tenían un estoma en el último seguimiento; 39 (24,8%) eran permanentes. CONCLUSIÓN: Las tasas de fuga anastomótica tras una TaTME fueron más altas que los datos nacionales con tasas de LR y patrones de crecimiento desfavorables.

Comparison of overall survival and quality of life between patients undergoing anal reconstruction and patients undergoing traditional lower abdominal stoma after radical resection.

BACKGROUND: Miles procedure is often necessary for patients with low rectal carcinoma. However, this operation often affects the quality of life of patients, to evaluate the advantages of improved operation (anal reconstruction), the quality of life and survival between patients undergoing anal reconstruction and patients undergoing traditional lower abdominal stoma after radical resection were analyzed. METHODS: The clinical data of 43 patients with low situated rectal carcinoma were retrospectively analyzed. 23 patients with left lower abdominal stoma after radical resection (Miles procedure) were divided into group A, and 20 patients with reconstruction of the anus in situ after radical resection were in group B. All patients were investigated by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-CR38 questionnaire, the clinical data are recorded. Independent sample T test was used to analyze the difference in quality of life between group A and group B at 3, 6, and 12 months after surgery, and Kaplan-Meier was used to compare the difference in overall survival between group A and group B. RESULTS: The results of T test showed that there were statistical significance in global health status and physical functioning between group A and group B at 3 and 6 months, but no statistical significance at 12 months (P = 0.024, P = 0.019, P = 0.115 for global health status; P = 0.004, P = 0.006, P = 0.065 for physical functioning, respectively). Emotional functioning and social functioning were also statistically significant between group A and group B at 3, 6, and 12 months (P = 0.041, P = 0.040, P = 0.034 for Emotional functioning; P = 0.020, P = 0.009, P = 0.032 for social functioning, respectively). This study also found that there was no statistical significance in body image and sexual functioning between group A and group B at 3 months, but there was statistical significance at 6 and 12 months(P = 0.098, P = 0.035, P = 0.045 for body image; P = 0.110, P = 0.048, P = 0.047 for sexual functioning, respectively). There were statistically significant about sexual enjoyment and defecation problems at 3, 6, and 12 months (P = 0.023, P = 0.028, P = 0.050 for sexual enjoyment; P = 0.013, P = 0.011, P = 0.050 for defecation problems, respectively).The results of Kaplan-Meier showed that the overall survival (OS) between group A and group B was not statistically significant (χ2 = 0.600, P = 0.439). CONCLUSIONS: There was no difference in survival time between group A and group B, but compared with the patients with left lower abdominal stoma(group A), the quality of life was better in patients with reconstruction of the anus in situ (group B). It is significant to improve the traditional lower abdominal stoma operation.

The limited prognostic value of liver histology in children with biliary atresia.

UNLABELLED: Background and rationale for the study. The aim of the study was to determine the prognostic value of histopathological findings with special care to the severity of liver fibrosis at the moment of hepatoportoenterostomy (HPE) in children with biliary atresia (BA). We performed analysis of 142 wedge liver biopsies taken at the time of HPE. All patients were operated by the same surgical team between 1995 and 2007. According to the outcome 6 months after HPE patients were divided into prognostic groups: group 1-bilirubin level < 2 mg% (n = 65), group 2-bilirubin level > 2 mg% (n = 77). Liver biopsies were re-evaluated according to the extended histopathological protocol and then were compared between the prognostic groups. Survival with native liver (SNL) estimates were performed in regard to severity of liver fibrosis. RESULTS: Survival with native liver estimates after 2, 5 and 10 years in patients after successful operation were 96%, 91%, 75% vs. 30%, 11%, and 5% if operation failed (p < 0.001). There was no difference between groups in the following variables: fibrosis (p = 0.69), portal inflammation (p = 0.99), lobular inflammation (p = 0.95), cholangiolitis (p = 0.23), accumulation of bile pigments (zone 1:p = 0.49; zone 2:p = 0.51; zone 3:p = 0.48), bile plugs in canaliculi (p = 0.12), bile plugs in ducts (p = 0.32), bilirubinostasis in hepatocytes (p = 0.45), bile ductular proliferation (p = 0.59), ductal plate malformation (p = 0.12), focal necrosis (p = 0.44), giant cell transformation (p = 0.45), haematopoesis (p = 0.52), ductopenia (p = 0.46), microabscesses (p = 0.49), ballooning of hepatocytes (p = 0.08). The actuarial 5/10-year SNL was not dependent on severity of liver fibrosis (log-rank test p = 0.84). The severity of fibrosis corresponded neither with the age at HPE nor with the laboratory findings before operation but increased the risk of portal hypertension. CONCLUSION: Liver histology at the time of HPE is of limited value in prognosis making in BA.

Continuous suture of the pancreatic stump and Braun enteroenterostomy in pancreaticoduodenectomy.

AIM: To investigate a new modification of pancreaticoduodenectomy (PD)-a mesh-like running suturing of the pancreatic remnant and Braun's enteroenterostomy. METHODS: Two hundred and three patients underwent PD from 2009 to 2014 and were classified into two groups: Group A (98 patients), who received PD with a mesh-like running suturing for the pancreatic remnant, and Braun's enteroenterostomy; and Group B (105 patients), who received standard PD. Demographic data, intraoperative findings, postoperative morbidity and perioperative mortality between the two groups were compared by univariate and multivariate analysis. RESULTS: Demographic characteristics between Group A and Group B were comparable. There were no significant differences between the two groups concerning perioperative mortality, and operative blood loss, as well as the incidence of the postoperative morbidity, including reoperation, bile leakage, intra-abdominal fluid collection or infection, and postoperative bleeding. Clinically relevant postoperative pancreatic fistula (POPF) and delayed gastric emptying (DGE) were identified more frequently in Group B than in Group A. Technique A (PD with a mesh-like running suturing of the pancreatic remnant and Braun's enteroenterostomy) was independently associated with decreased clinically relevant POPF and DGE, with an odds ratio of 0.266 (95%CI: 0.109-0.654, P = 0.004) for clinically relevant POPF and 0.073 (95%CI: 0.010-0.578, P = 0.013) for clinically relevant DGE. CONCLUSION: An additional mesh-like running suturing of the pancreatic remnant and Braun's enteroenterostomy during PD decreases the incidence of postoperative complications and is beneficial for patients.

Enterostomy can decrease the mortality of patients with Fournier gangrene.

AIM: To determine the significance of enterostomy in the emergency management of Fournier gangrene. METHODS: The clinical data of 51 patients (49 men and 2 women) with Fournier gangrene who were treated at our hospital over the past 12 years were retrospectively analyzed. The patients were divided into two groups according the surgical technique performed: enterostomy combined with debridement (the enterostomy group, n = 28) or debridement alone (the control group, n = 23). Patients in the enterostomy group received thorough debridement during surgery and adequate local drainage after surgery, as well as administration of broad-spectrum antibiotics. The clinical data and outcomes in both groups were analyzed. RESULTS: The surgical procedures were successful in both patient groups. In the enterostomy group, 10 (35.8%) patients required skin grafting with a total of six debridement procedures. While in the control group, six (26.1%) patients required four debridement procedures. However, this difference was not statistically significant. Following surgery, the time to normal body temperature (6 d vs 8 d, P < 0.05) and average length of hospital stay (14.3 ± 7.8 d vs 20.1 ± 8.9 d, P < 0.05) were shorter in the enterostomy group. The case fatality rate was lower in the enterostomy group than that in the control group (3.6% vs 21.7%, P < 0.05). CONCLUSION: Enterostomy can decrease the case fatality rate of patients with Fournier gangrene.

Percutaneous metallic stent placement in patients with cancer recurrence at bilioenterostomy site.

PURPOSE: To investigate the outcomes of percutaneous metallic stent placement in patients with malignant bilioenterostomy obstruction and to assess the risk factors influencing stent patency. MATERIALS AND METHODS: From August 2008 to January 2012, 53 patients with malignant bilioenterostomy obstructions were treated with percutaneous placement of biliary metallic stents; this included expanded polytetrafluoroethylene (ePTFE)-covered stent placement in 36 patients and uncovered stent placement in 17 patients. RESULTS: A total of 75 stents were successfully placed in 53 patients. No major complications occurred in any patients, and minor complications occurred in nine patients (17%). The mean serum bilirubin level, which was 3.6 mg/dL ± 0.7 before drainage, decreased significantly to 2.5 mg/dL ± 0.4 at 1 month after stent placement (P = .041). Successful internal drainage was achieved in 44 of the 53 patients (83%). Kaplan-Meier analysis showed a median overall survival time of 145 days (95% confidence interval, 100-190 d), a median stent patency time of 313 days (95% confidence interval, 46-580 d), and cumulative stent patency rates at 1, 3, 6, 9, and 12 months of 91%, 75%, 64%, 56%, and 45%, respectively. Multivariate Cox regression analysis showed that the use of uncovered stents (odds ratio, 2.924; P = .033) was the only significant independent factor associated with stent occlusion. CONCLUSIONS: Percutaneous metallic stent placement is a safe and effective method for the treatment of patients with malignant bilioenterostomy obstruction. Moreover, as uncovered stent placement is the only significant independent factor associated with stent occlusion, ePTFE-covered stent placement is preferable in these patients.

Comparative study of morbidity and mortality between ileal conduit and ureterosigmoidostomy after radical cystectomy for bladder neoplasm.

OBJECTIVES: Despite the growing trend in the development of orthotopic neobladders, the procedure cannot be performed in many cases, thereby retaining the validity of other techniques. We propose a comparative analysis between patients with radical cystectomy for bladder neoplasm and reconstruction using the ileal conduit (IC) or ureterosigmoidostomy (USG). PATIENTS AND METHOD: Observational retrospective study on 255 patients with radical cystectomy between 1985 and 2009, selecting group assignments by the use of IC and USG. Analysis of the demographic and preoperative characteristics, perioperative complications, pathology and medium to long-term complications. Comparison of groups using T-Student, U-Mann-Whitney and chi square tests, with P<.05 indicating statistical significance. Preparation of survival tables according to Kaplan-Meier, establishing comparisons using the log-rank test. RESULTS: There were 41 cases of IC and 55 cases of USG, with a mean patient age of approximately 61 years. USGs were performed on a greater number of females than ICs. There were no differences in the need for transfusion, with similar results as other series. There was a greater trend towards the appearance of intestinal fistulae and greater morbidity and mortality in the postoperative period in USG, although it was not significant. There was a greater long-term presence of eventrations in IC, and of pyelonephritis and the need for taking alkalinizing agents in USG. The appearance of peristomal hernias in IC was less than in previous series. With a mean follow-up greater than 50 months, the overall survival was 40% at 5 years, with no differences according to urinary diversion. CONCLUSIONS: IC and USG are two applicable urinary diversions in the event that orthotopic neobladder surgery cannot be performed. They have a similar long-term complication and survival profile in our series, although with a higher morbidity in postoperative complications for USG.

Enterostomy complications in infancy and childhood.

BACKGROUND: A number of severe gastrointestinal disorders in infancy and childhood may require the formation of an enterostomy as a crucial part of the treatment of the disease itself. This study reviews our pediatric patients with regard to the morbidity and mortality of enterostomy formation and closure over an 8-year period. PATIENTS AND METHODS: Sixty-eight enterostomies in infants and children and 60 consecutive enterostomy closures in retrospect are reported on. This includes colostomies, jejunostomies, ileostomies, and Mikulicz procedures. RESULTS: In most instances, a transverse colostomy was performed. The most frequent indications were intestinal obstruction and necrotizing enterocolitis. More than half of the children were less than 1 month of age at the time of surgery. We observed an overall complication rate of 38.2% following enterostomy formation, with stoma prolapse being the most common, but faced major complications (such as sepsis, peritonitis, and enterocutaneous fistula) in only 10.3%. Complications after enterostomy closure were encountered in 20%. The overall mortality was 7%. CONCLUSION: Enterostomy formation and closure in the pediatric age group with severe underlying disease is still associated with substantial morbidity.

Intestinal atresia with gastroschisis: a selective approach to management.

BACKGROUND: The association of bowel atresia with gastroschisis is well recognized, but the ideal management is less certain. METHODS: The records of 10 infants with gastroschisis and intestinal atresia treated between 1991 and 1997 in a single neonatal surgical unit were reviewed. RESULTS: Ten infants had midgut atresias: 5 small intestine, 1 jejunum and colon, and 4 colonic. Of the 6 with small bowel atresias, 4 had primary abdominal wall repair with electively delayed primary anastomosis at 21 to 46 days, 1 had decompressing tube jejunostomy at 11 days at the time of secondary abdominal closure, and 1 initial jejunostomy. Of the 4 with colonic atresia alone, 3 had perforation or infarction of the proximal colon at birth, 2 had a primary stoma, and 2, who did not have initial colostomy or anastomosis, required reoperation for increasing abdominal distension at 11 and 23 days. Complications were recorded in 6 patients: 2 had necrotizing enterocolitis after which 1 developed malabsorption, 1 had distal bowel obstruction after delayed primary anastomosis treated with a Bishop-Koop ileostomy at 50 days, 2 had stoma stenosis, and 1 had stoma prolapse. None died, and at 1 year 9 were within the normal range for body weight, and details of 1 are not known. CONCLUSIONS: At birth, diagnosis of atresia often is uncertain, and the bowel is difficult to repair or exteriorize. For proximal atresias, delayed primary repair is a safe satisfactory approach. At birth, distal atresias are more obvious, often complicated by perforation or infarction, and may benefit from early enterostomy.

Successful use of the "patch, drain, and wait" laparotomy approach to perforated necrotizing enterocolitis: is hypoxia-triggered "good angiogenesis" involved?

The traditional and most frequently employed surgical approach to perforated necrotizing enterocolitis (NEC), laparotomy and bowel resection with enterostomy creation, has been associated with an unacceptably high mortality and major morbidity (sepsis, short-gut syndrome, strictures, long-term total parenteral nutrition (TPN), prolonged and costly hospitalizations with multiple operations, the inevitable open-and-close procedure for "hopeless" extensive gut ischemia in approximately 10% of laparotomy cases, etc.). The use of the laparotomy "patch, drain, and wait" (PD&W) approach to this serious of NEC complication has provided a simple, direct, and effective means of dealing with this problem. The basic principle is to resect no gut and do no enterostomies. The details are presented here as well as the multiple types of "patching" and the importance of use of extensive direct-vision draining with bilateral small Penrose drains from the undersurfaces of both diaphragms into the pelvis with exit sites in both lower quadrants. Proper and effective patching and draining cannot be done blindly,but requires direct vision (laparotomy or laparoscopy). The critical components and timing of the "waiting" are emphasized, including the vital importance of strict avoidance of early post-drainage laparotomy in the 7- to 14-day post-drainage period (whether the drainage is percutaneous, laparotomy PD&W, or laparoscopy PD&W) due to the early, life-threatening-ending hypervascularity that occurs at this time and if left unmolested will function beneficially as life- and gut-saving "good angiogenesis". The bilateral Penrose drains capture fecal fistulas and function quite well as de-facto enterostomies as the peritoneal cavity is rapidly obliterated by adhesions and massive, florid hypervascularity/gut hypoxia triggered "good angiogenesis" (no peritoneal cavity, no peritonitis). Broad-spectrum triple antibiotics and the routine use of TPN contribute to favorable results. The lessons/experiments of nature encountered in newborns with midgut atresia(s) and remarkable levels of gut survival, in the occasional case with only meconium peritonitis and no obstruction ("auto-anastomosis") are pertinent here as the TPN of PD&W is provided in atresia(s) by the maternal-placental circulation and the sterile peritoneal cavity of atresia(s) is simulated by the combination of antibiotics and peritoneal-cavity obliteration. Life- and gut-saving "good angiogenesis" is common to both situations. A 15-year personal experience with the PD&W laparotomy approach to perforated NEC in 23 cases is reported here with no mortality in the initial 60 postoperative days, no major morbidity, and no second operation required in 70% (spontaneous "auto-anastomosis") of cases. All infants with extensive gut ischemia/necrosis (NEC totalis) who would otherwise be classified as "hopeless" and managed by open-and-close only were managed in this experience successfully by PD&W with preservation of both life and an adequate amount of gut, although a second operation was required in these cases to re-establish intestinal continuity. A particularly striking observation was the rapid transition of these infants from profound illness to near-normalcy in a matter of hours after the initiation of PD&W--much like the rapid clinical changes accompanying the lancing of a boil or an abscess. An involvement of hypoxia-induced "good angiogenesis" with marked hypervascularity and involving molecules, genes, and receptors of the vascular endothelial growth factor family of hypoxia-induced angiogenesis molecules is speculated upon, and clinical studies to document these speculations are suggested as well as studies evaluating the potential of laparoscopic PD&W. The usefulness of Argyle chest-tube "venting" and "stenting" by trans-anal passage above colonic "patched" areas as seen in 2 cases is worthy of further study and use.

High morbidity of enterostomy and its closure in premature infants with necrotizing enterocolitis.

OBJECTIVE: To review the morbidity and mortality among 68 premature infants treated with enterostomy for necrotizing enterocolitis. DESIGN: Data were collected retrospectively from hospital medical records to include the period between January 1, 1987, and September 30, 1997. SETTING: Tertiary care children's hospital. PATIENTS: A group of 68 infants aged 2 to 35 days (mean age, 12.5 days), weighing 1500 g or less, with necrotizing enterocolitis necessitating surgical enterostomy for treatment. INTERVENTIONS: Creation of any enterostomy during exploratory laparotomy for necrotizing enterocolitis and subsequent closure. MAIN OUTCOME MEASURES: Morbidity and mortality associated with infant enterostomy and its closure. RESULTS: Thirty-nine infants underwent ileostomy with mucous fistula, 16 underwent ileostomy with a Hartmann pouch, 7 had jejunostomy with mucous fistula, 2 had colostomy with mucous fistula, and 4 had colostomy with a Hartmann pouch. Eighteen (26%) of the 68 infants died in the postoperative period of sepsis (n = 10), continuing necrotizing enterocolitis (n = 5), or respiratory distress (n = 3). Of the remaining 50 infants, complications developed in 34 (68%). These complications included strictures requiring further resection at the time of enterostomy closure in 20 infants; stricture of the enterostomy requiring surgical revision in 6; incisional hernia in 3; parastomal hernia in 4; enterostomal prolapse or intussusception in 6 and 1, respectively; wound dehiscence in 4; wound infection in 8; small-bowel obstruction requiring laparotomy in 2; and anastomotic complications in 2. Only 16 enterostomies were closed uneventfully, with 3 of these infants subsequently dying of sudden infant death syndrome between 6 and 8 months after the operation. Of the surviving infants, 3 (6%) continue to require home hyperalimentation. CONCLUSIONS: Although enterostomy in infants with low birth weight with necrotizing enterocolitis may be lifesaving, it is also a major cause of morbidity. These data suggest the feasibility of a prospective study comparing resection and primary anastomosis with resection and enterostomy.

A report of 27 cases of congenital short colon with an imperforate anus: so-called 'pouch colon syndrome'.

This is a retrospective study of 27 cases of congenital short colon with anorectal malformation (pouch colon syndrome) treated during the last 5 years (from January 1991 to December 1995). The radiological feature of enormously dilated colonic pouch occupying more than half the width of abdomen was diagnostic in almost all cases. Excision of pouch and end enterostomy was associated with maximum survival (92.3%) in good risk patients. Proximal diverting enterostomy with decompression and irrigation of pouch is a preferable alternative to pouch colostomy in poor risk patients. Tapering coloplasty and colostomy should be reserved only for types I and II cases of pouch colon.

[14-year experience with surgical treatment of chronic pancreatitis]. / 14-letnie doswiadczenia w chirurgicznym leczeniu przewleklego zapalenia trzustki.

The authors discuss their own 14-year experience with surgical treatment of the chronic pancreatitis. They treated 64 patients of a mean age of 43 years. An abdominal pain, persisting in all patients, constituted the main indication to surgery. Forty patients underwent pancreatic enterostomy with Puestow technique, 19 patients resections of various extension, and 5 patients underwent pancreatic duodenostomy. Mortality rate in pancreatic enterostomy and pancreatic duodenostomy was 2.5% whereas mortality rate in resections was 5.3%. Complications were noted in 27.5% and 36.8% of patients, respectively. Pain was completely abolished or markedly reduced in 90% of patients. Forty eight (77.4%) out of 62 patients were identified and followed up. According to commonly used criteria, positive late results were achieved in 56.2% of patients, moderate in 29.2%, and poor result in 14.6% of the treated patients.
