DISSEMINATED PERITONEAL LEIOMYOMATOSIS - A RARE ENTITY, COMPLICATED BY LATE BLEEDING FROM THE ILEOCOLIC VEIN.

Leiomyomatosis peritonei or disseminated peritoneal leiomyomatosis (DPL) is an extremely rare condition affecting mainly women of childbearing age with estrogen hypersecretion. It is characterized by the presence of multiple histologically benign smooth muscle nodules on the peritoneal surface and subperitoneal tissue mimicking peritoneal carcinomatosis. There are no clear guidelines for the primary management and follow-up o these patients. Case report: We represent a 44-years-old woman admitted due to two retroperitoneal tumors diagnosed on routine ultrasound screening. There was a past history of hysterectomy for uterine leiomyoma. The blood assay was normal. MRI revealed two well-circumcised tumors with a size of 15 cm and 6 cm, respectively, with a characteristic of leiomyoma. The tumors were removed completely. Macroscopically, they appeared as well-circumscribed masses with grey to white color, a rubbery texture, and a whorled cut surface. On the first postoperative day, due to a sudden drop of hemoglobin from 127 g/L to 6.8 g/L and clinical signs of acute intra-abdominal bleeding, the patient was reoperated. The site of bleeding was from the ileocolic vein located at the lower pole of the tumor. It was successfully controlled by ligation. The patient had an uneventful recovery. After five years she is free of recurrence. DPL is a rare disease, sometimes mimicking peritoneal carcinomatosis. The preoperative diagnosis should be suspected in women of childbearing age with estrogen hypersecretion and concurrent uterine leiomyomas. The management depends on the patient's age, reproductive plans, multiplicity, and symptomatology of DPL. Single tumors are best treated by surgery with synchronous hysterectomy or myomectomy in case of uterine myomatosis. In the case of symptomatic multiple DPL and fulfilled reproductive plan, bilateral salpingo-oophorectomy or treatment with Gonadotropin-releasing hormone analogs is indicated. In asymptomatic multiple DPL, the removal of all nodules is not mandatory because of the benign indolent course. The long-term prognosis of DPL is excellent.

Ileus caused by small bowel, ileocaecal and rectal endometriosis misdiagnosed as Crohn's disease and managed by synchronous ileocaecal and rectal resection.

The reported incidence of intestinal endometriosis varies between 22% and 37%, with bowel obstruction in only 2.3% of cases, but few series report acute obstruction. We report a rare case of acute bowel obstruction due to multiple bilateral deep intestinal endometriosis lesions localised in the ileum, ileocaecal valve and upper rectum, requiring synchronous resection in an emergency setting. A 42-year-old woman was referred to our clinic with a diagnosis of obstructing Crohn's disease based on abdominal computed tomography with oral contrast showing a thickened terminal ileum with stenosis, compression of the caecum and proximally dilated small bowel loops. Simultaneous ileocaecal resection and segmental resection of the upper rectum with handsewn end-to-end anastomosis between the sigmoid colon and rectum was performed. Owing to the advanced bowel obstruction and significant weight loss, a double barrelled ileoascendostomy was created. The patient had an uneventful recovery. Histological examination revealed transmural endometriosis with involvement of the pericolic fat in both specimens. Although intestinal endometriosis causing acute bowel obstruction is rare, it should be included among the differential diagnoses in young women with recurrent abdominal pain, intermittent diarrhoea and constipation without a family history for inflammatory bowel disease or cancer. Bleeding synchronous with menstruation is not typical for intestinal endometriosis. Right-sided intestinal endometriosis more frequently causes acute bowel obstruction, in most cases due to intussusception.

An analysis of missed cases with surgical emergencies admitted in non-surgical departments. Case series and а review of the literature.

INTRODUCTION: The delayed diagnosis in emergency surgery can be associated with significant morbidity and mortality and often lead to litigations. The aim of the present work is to analyse the outcome in cases with non-trauma surgical emergencies wrongly admitted in non-surgical departments. METHODS: A retrospective trial in two independent University hospitals was conducted. The first group encompassed the patients worked-up in the Surgical unit of Emergency department (2014-2018). The second one included all cases visited Emergency department (2018). Only cases with acute abdomen and delayed diagnosis and operation were included. The analysis included the proportion of the delayed diagnosis, time between admission and operation, intraoperative diagnosis, complications and mortality rate. RESULTS: In the first group there were 30 194 visits in the surgical unit with 15 836 hospitalizations (52.4%). Twenty patients of the last (0.13%) were admitted in the Clinic of Infectious disease and subsequently operated. The mean delay between hospitalization and operation was 3 days (1-10). Seventeen patients (85%) were operated with mortality of 10%. In the second group, there were a total of 22 760 visits with 11 562 discharged cases. Of the last, 1.7% (n=192) were re-admitted in a surgical ward, 25 of which underwent urgent surgery (0.2%). CONCLUSIONS: The missed surgical cases represent only a small proportion of the patients in emergency department. The causes for wrong initial admissions in our series were misinterpretation of the symptoms, insufficient clinical examination and underuse of US and CT. The careful clinical assessment, point-of care US and CT may decrease the rate of the delayed diagnosis.

Endoluminal negative pressure therapy in colorectal anastomotic leaks.

AIM: The aim of the present work was to perform an up-to-date review of the literature on endoluminal negative pressure therapy for colorectal anastomotic leak. METHOD: An electronic search in PubMed and Google Scholar and a manual search without language restrictions were performed on 25 January 2019. Only original series reporting endoluminal negative pressure therapy in colorectal anastomotic leaks were included. The primary outcome was the success rate (complete closure of the abscess cavity). The secondary outcomes were the rates of complications and stoma closure. RESULTS: Nineteen series with a total of 295 cases were analysed. The median distance of the anastomosis from the anal verge and the size of the abscess were 5.65 cm (4.9-10) and 6.0 cm (5-8.1) respectively. In 84.5% (78%-91%) the stoma was created at the first intervention. Neoadjuvant therapy was performed in 48.6% (3%-60%). Median 7 sponges (2-34) were used with median negative pressure 150 mmHg (125-700) for a median of 31 days (14-127). The success rate was 85.4% (80%-91%) with ileostomy closure in 72.6%. Complications were observed in 19% (13%-25%): abscesses 11.5% and anastomotic stenosis 4.4%. Laparotomy was required in 15% of the complications. The stoma was the only significant predictor for the success of the therapy (0.007, SE 0.004, P = 0.040). CONCLUSIONS: The initial experience looks promising with an 85% success rate, which precludes risky re-resections with redo anastomosis or Hartmann's procedure. Despite the good initial results, definitive conclusions cannot be drawn because of the small sample size and the lack of high-quality comparative studies.

A rare case of life-threatening extra-peritoneal bleeding a.

INTRODUCTION: Although inguinal hernia repair is a routine procedure and frequently performed as one-day surgery, we should be particularly aware of the possible complications, which could be life-threatening if not recognized in due course. CASE REPORT: We report a case of life-threatening extra-peritoneal bleeding after open inguinal hernia repair requiring damage control surgery. DISCUSSION: Several vessels can be responsible for massive extraperitoneal bleeding - external iliac vessels, lower epigastric artery, crema steric vessels and corona mortis. Although damage control surgery was developed to treat the severe trauma, it can also be a life-saving maneuver in cases as the presented one. Hemodynamic instability with distended abdomen is a primary indication for laparotomy, but in some cases the contrast CT provides valuable information about the location and the size of hematoma and can guide the operative approach - midline laparotomy or revision of the wound as in our case. To the best of our knowledge, this is the first reported case of life-threatening retroperitoneal bleeding after open inguinal hernia repair. The present case is a good example for the application of damage control in pathology considered as one-day surgery. CONCLUSIONS: Although casuistic, the life-threatening bleeding after open hernia repair should be suspected. The prompt surgical response with damage control can be life-saving maneuver even in the routine hernia surgery. Detailed knowledge of the anatomy and carefull dissection are required to avoid this kind of complications.

Sigmoid resection for diverticular disease - to ligate or to preserve the inferior mesenteric artery? Results of a systematic review and meta-analysis.

AIM: In colorectal cancer, ligation of the inferior mesenteric artery (IMA) is a standard surgical approach. In contrast, ligation of the IMA is not mandatory during treatment of diverticular disease. The object of this meta-analysis was to assess if preservation of the IMA reduces the risk of anastomotic leakage. METHOD: A search was performed up to August 2018 using the following electronic databases: MEDLINE/PubMed, ISI Web of Knowledge and Scopus. The measures of treatment effect utilized risk ratios for dichotomous variables with calculation of the 95% CI. Data analysis was performed using the meta-analysis software Review Manager 5.3. RESULTS: Eight studies met the inclusion criteria and were included in the meta-analysis: two randomized controlled trials (RCTs) and six non-RCTs with 2190 patients (IMA preservation 1353, ligation 837). The rate of anastomotic leakage was higher in the IMA ligation group (6%) than the IMA preservation group (2.4%), but this difference was not statistically significant [risk ratio (RR) 0.59, 95% CI 0.26-1.33, I2  = 55%]. The conversion to laparotomy was significantly lower in the IMA ligation group (5.1%) than in the IMA preservation group (9%) (RR 1.74, 95% CI 1.14-2.65, I2  = 0%). Regarding the other outcomes (anastomotic bleeding, bowel injury and splenic damage), no significant differences between the two techniques were observed. CONCLUSION: This meta-analysis failed to demonstrate a statistically significant difference in the anastomotic leakage rate when comparing IMA preservation with IMA ligation. Thus, to date there is insufficient evidence to recommend the IMA-preserving technique as mandatory in resection for left-sided colonic diverticular disease.

Laparoscopic versus open colectomy for obstructing right colon cancer: A systematic review and meta-analysis.

BACKGROUND: Hemicolectomy is the treatment of choice for intestinal obstruction from right colon cancer. This review compares the laparoscopic vs open access in hemicolectomy for patients with right colon cancer. METHODS: A systematic review and meta-analysis of clinical studies published after January 2017 was performed according to the Prisma guidelines. The study has been recorded on the Prospero register (CRD42016044108). RESULTS: Five studies were included for review. Only one anastomotic leak was reported in conventional open anastomosis group (1.9%) and none of the studies included in the meta-analysis reported re-operations during the first 30 postoperative days. The 30-day postoperative mortality did not differ between the two groups. The length of incision, blood loss, early mobilization after surgery, the 30-day postoperative overall complication rate and hospital length of stay were significantly shorter in the laparoscopic group. The difference in the duration of procedure was statistically significant in favor of the open group. The number of dissected lymph nodes, the overall survival at 5 years and time to flatus were described only in one study, without any significant difference. Finally, none of the trials reported any information concerning differences in the costs between the two techniques. CONCLUSIONS: The better outcomes described in this study achieved with laparoscopy, must be interpreted with caution because of the small number of patients involved, the selection and publication bias and the low level of evidence of the analysed trials. Indeed, the advantages of a minimally invasive approach, which have been demonstrated by the present meta-analysis, should encourage the use of laparoscopy also in emergency setting.

A systematic analysis of controlled clinical trials using the NiTi CAR™ compression ring in colorectal anastomoses.

Anastomotic leak following colorectal surgery can be a devastating adverse event. The ideal stapling device should be capable of rapid creation of an anastomosis with serosal apposition without the persistence of a foreign body or a foreign body reaction which potentially contribute to early anastomotic dehiscence or late anastomotic stricture. A systematic review was performed examining available data on controlled randomized and non-randomized trials assessing the NiTi compression anastomosis ring-(NiTi CAR™) (NiTi Solutions, Netanyah Israel) in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards. A protocol for this meta-analysis has been registered on PROSPERO (CRD42016050934). The initial search yielded 45 potentially relevant articles. After screening titles and abstracts for relevance and assessment for eligibility, 39 of these articles were eventually excluded leaving 6 studies for analysis in the review. Regarding the primary outcome measure, the overall anastomotic leak rate was 2.2% (5/230) in the compression anastomosis group compared with 3% (10/335) in the conventional anastomosis group; this difference was not statistically significant (RR 0.75, 95% CI 0.25-2.24; participants = 565; studies = 6; I 2 = 0%). There were no statistically significant differences between compression and conventional anastomoses in any of the secondary outcomes. This review was unable to demonstrate any statistically significant differences in favor of the compression anastomosis technique over conventional manual or stapled mechanical anastomoses.

Open abdomen and VAC® in severe diffuse peritonitis.

BACKGROUND: Currently, the open abdomen technique is the widely recognised method for treatment of life-threatening trauma, intra-abdominal sepsis, abdominal compartment syndrome and wound dehiscence. The techniques for temporary closure using negative pressure have gained increasing popularity. Although negative pressure wound therapy has been proved as an effective method in trauma, the results in diffuse peritonitis are contradictory. METHODS: Overall, 108 patients with diffuse peritonitis and open abdomen were prospectively enrolled from January 2006 to December 2013--69 treated with mesh-foil laparostomy without negative pressure and 49 with vacuum-assisted closure (VAC(®)) The primary endpoints were the rate of primary fascial closure and mortality. The secondary outcomes were the rate of complications--enteroatmospheric fistulas, intra-abdominal abscesses, wound infection and necrotising fasciitis, intensive care unit (ICU) and overall hospital stay. RESULTS: VAC was associated with higher overall (73% vs 53%) and late primary fascial closure rates (31% vs 7%), lower rates of necrotising fasciitis (2% vs 15%, p=0.012), intra-abdominal abscesses (10% vs 20%), enteroatmospheric fistulas (8% vs 19%), overall mortality (31% vs 53%, p<0.05), shorter ICU (6.1 vs 10.6 days, p=0.002) and hospital stay (15.1 vs 25.9 days, p=0.000). CONCLUSIONS: The results clearly suggest the obvious advantage of VAC in comparison to the temporary abdominal closure without negative pressure in the cases with severe diffuse peritonitis. However, to a large extent, our results might be attributed to the combination of VAC with dynamic fascial closure.

A case of synchronous bleeding from esophageal varices and appendixin a patient with decompensated liver cirrhosis.

UNLABELLED: Lower gastrointestinal bleeding is defined as any bleeding localized distally to Treitz's ligament. The massive bleeding from the appendix is extremely rare and only 21 cases described in the English literature. CASE PRESENTATION: We present a 61-years-old patient with decompensated liver cirrhosis and bleeding from esophageal varices. He underwent band ligation by Six Shooter (Cook Medical, USA). Due to a massive bleeding from the lower gastrointestinal tract and a rapid decline of hemoglobin level to 3 g/dL, angiography was performed. It revealed a bleeding from distal branches of ileocolic artery, confirmed by the followed computed tomography angiography. The patient underwent appendectomy and was discharged in a good condition on the 6th postoperative day. CONCLUSION: The synchronous bleeding from upper and lower GIT should be considered, especially in the cases with portal hypertension. The angiography and computed tomography angiography are valuable diagnostic methods, able to localize the bleeding a thus to reduce the morbidity and mortality.

Damage control surgery and open abdomen in trauma patients with exsanguinating bleeding.

UNLABELLED: Acute coagulopathy with exsanguinating bleeding occurs in 2-5% of all trauma cases carrying mortality rate near 100% after conventional management. In the last few decades, the development of damage control surgery (DCS) in combination with the technique of open abdomen led to significantly improved survival among these patients. MATERIAL AND METHODS: A descriptive study based on a retrospective analysis of 12 consecutive blast victims with exsanguinating bleeding underwent DCS and open abdomen management. All patients were soldiers injured during their deployment in Iraq and Afghanistan during 2002-2007, treated by our deployed surgical teams. Vacuum Assisted Closure (V.A.C., KCI) and vacuum pack (VP) was used for a temporary closure of abdomen. A cumulative analysis of all relevant series used these methods during the period 2000-2013 was performed. RESULTS: DCS was applied in 12 of 114 consecutive blast victims (10.5%) with survival rate 66.7% (8/12). Eleven had open abdomen with temporary closure with V.A.C. in 6 and VP in 5. Four patients died before the definitive closure (36.4%). The survivors (n = 8) were with a mean age 28.5 years, suffered from a critical trauma with a mean Injury Severity Score 35.5. V.A.C was used in 4 of them, VP in 3. Primary closure of abdomen was achieved in 6 (85.7%) within 3.5 days and mean 1.3 dressing changes. Due to ACS, the abdomen was closed through skin suture only and a creation of planned ventral hernia in 1 patient treated with VP (1/7, 14.3%). Wound infection was observed in 1 case (14.3%). CONCLUSION: Despite the small sample size, our series clearly demonstrate the benefits of DCS and open abdomen in trauma patients with exsangiunating bleeding. The survival rate is highly dependent on the rapid implementation of DCS in properly selected patients. V.A.C. and VP provide a high rate of primary fascial closure in trauma.
