RESUMO

Bile leak is a rare complication after Laparoscopic Cholecystectomy. Subvesical bile duct (SVBD) injury is the second cause of minor bile leak, following the unsuccessful clipping of the cystic duct stump. The aim of this study is to pool available data on this type of biliary tree anatomical variation to summarize incidence of injury, methods used to diagnose and treat SVBD leaks after LC. Articles published between 1985 and 2021 describing SVBD evidence in patients operated on LC for gallstone disease, were included. Data were divided into two groups based on the intra or post-operative evidence of bile leak from SVBD after surgery. This systematic report includes 68 articles for a total of 231 patients. A total of 195 patients with symptomatic postoperative bile leak are included in Group 1, while Group 2 includes 36 patients describing SVBD visualized and managed during LC. Outcomes of interest were diagnosis, clinical presentation, treatment, and outcomes. The management of minor bile leak is controversial. In most of cases diagnosed postoperatevely, Endoscopic Retrograde Cholangio-Pancreatography (ERCP) is the best way to treat this complication. Surgery should be considered when endoscopic or radiological approaches are not resolutive.

RESUMO

INTRODUCTION AND IMPORTANCE: In the last years, transanal total mesorectal excision (TaTME) has been described in rectal cancer treatment, especially in challenging patients, difficulties in pelvic exposure and limitations of instrumentation improving not only dissection but also the preservation of autonomic pelvic nerves and the achievement of a restorative procedure. Here we report a case report of anterior laparoscopic rectal resection for adenocarcinoma of the high-mid rectum converted to transanal approach. CASE PRESENTATION: A 69-year-old male presented hepatic nodules during radiological follow-up for prostate cancer treated with radical prostatectomy and adjuvant radiotherapy (70 Gy). The biopsy of the lesion demonstrated the presence of a metastatic lesion of an adenocarcinoma, with suspected intestinal origin. Then, we perform an endoscopic examination, which showed the presence of a rectal lesion, which cause a bowel stenosis extended from the middle part to the upper part of the rectum. After chemoradiotherapy, an anterior rectal resection was performed. During surgery we could not perform the resection of the rectum due the thickness and fibrosis of the tissue, despite we used different branded mechanical stapler. So, we decided to complete the surgical treatment starting a TaTME procedure with resolution of the problem. CLINICAL DISCUSSION: TaTME is a relatively new technique that had already become a valid option in the treatment of low rectal cancer, and, nowadays, also in the treatment of inflammatory bowel disease. As reported in literature, this technique has a number of advantages, especially in narrow pelvis and it is very useful in low rectal surgery. CONCLUSION: This case report aims to describe the possible use of TaTME procedure as a rescue also when this approach is not the first choice.

RESUMO

BACKGROUND: Transanal dissection of the rectum has been recently introduced for ileal pouch-anal anastomosis (IPAA) in UC showing promising results. Thanks to the precise identification of the rectotomy site the risk of long rectal stump is avoided, and a single stapled anastomosis is performed easily. The aim of this study is to analyze our initial experience of transanal proctocolectomy and ileal pouch-anal anastomosis (TaIPAA), considering postoperative complications and medium-term functional outcomes. METHODS: Our Center has experienced the transanal approach for proctectomy and IPAA since August 2018. All patients underwent Enhanced Recovery After Surgery (ERAS) protocol. Postoperative complications occurring within 30 days after surgery were taken into consideration. Fecal continence, genito-urinary activity and global quality of life at 1 and 6 months after ileostomy reversal have been assessed. RESULTS: Until March 2019, 8 patients underwent transanal proctocolectomy and ileal pouch-anal anastomosis (TaIPAA). In all cases the laparoscopic approach was performed during the transabdominal phase; abdominal drainage was never used. At the time of the pouch construction a defunctioning loop ileostomy was created in all patients. Stoma closure was performed in all cases at a median time of 6 months after surgery. Postoperative complications occurred in only one patient, who showed rectal bleeding, not required a re-invertation. There were no cases of anastomotic leakage. Medium-term functional outcomes were determined prospectively using previously validated quality of life questionnaires (Cleveland Global Quality of Life). Fecal incontinence for liquid or solid stool, genitourinary and sexual functions were also investigated, showing comparable results with the literature data. CONCLUSIONS: In our experience, transanal proctocolectomy and ileal pouch-anal anastomosis provided good short and medium-term functional results in UC.

RESUMO

INTRODUCTION: The current Tumor Node Metastasis staging system (TNM) for gastric cancer classifies the extent of lymph node metastasis based upon the number of lymph nodes involved. Choi et al. have recently proposed a new anatomical classification based upon the regionality of the involved nodes. This new classification seems to have a better predictive prognostic value than the traditional one. We investigated the prognostic role of the new anatomical based classification, reviewing our institutional gastric cancer database. METHODS: We performed a retrospective chart review of 329 patients who underwent gastrectomy at our Institution from 2003 to 2017. We excluded from data analysis any patient with distant metastases at the time of first diagnosis and or surgery, pathology other than adenocarcinoma, lymphadenectomy less than D2, impossibility to identify location of lymph nodes (LNs) on pathological report and neoadjuvant chemotherapy. The extent of D2 lymphadenectomy was defined according to Japanese Gastric Cancer Association criteria. LN metastasis were reclassified into three topographic groups (lesser, greater curvature, and extraperigastric nodes) and staged according to Choi. The new N stage was combined with the current pT according to the 8th edition of TNM and a new hybrid TNM stage was established. All patients were followed up until June 2019. The prognostic performance of the new stage and of the current anatomical numeric based system (TNM) was analyzed and assessed by the C-index, AIC and likelihood ratio χ2 value. RESULTS: In predicting both Overall Survival (OS) and Disease free Survival (DFS) the new N stage and the new TNM staging system had the highest C-index and likelihood ratio χ2 value and the lowest Akaike Information Criterion (AIC), showing a better accuracy and displaying a better prognostic performance. CONCLUSIONS: Our study is the first from the Western world to compare the new hybrid classification, based on the anatomical location of metastatic nodes, to the 8th of American Joint Committee on Cancer (AJCC) TNM staging system. Our findings on a small, monocentric sample suggest that hybrid topographic lymph node staging system is more accurate than TNM.

RESUMO

BACKGROUND: Valdoni technique involves leaving the mucosa layer, between the two anastomosed bowel tract intact, providing for a subsequent breakage of the intestine. It is a technique that allows you to keep the operating field clean.Surgical technique and Case Report: We describe the Valdoni technique. We also report a case of 75 years old man affected by an ascending colon cancer with no metastasis. The patient underwent right hemicolectomy. Making the anastomose, the surgeon did the Valdoni technique, with no intraoperative complications.The postoperative course was characterized by an abdominal pain with swollen abdomen, no flatus and vomit. A computed tomography (CT) revealed a sub-stenosis of the anastomose. We decided to do an urgent colonoscopy, with a resection of the mucosa layer not totally opened, using a Needle-knife Precut. The post procedure course was uneventful. The patient was discharged three days later. CONCLUSION: Valdoni technique allows the surgeon to keep the operating field clean. It is a valid alternative when the surgeons have to make a colonic anastomosis, doing open surgery.

RESUMO

INTRODUCTION: Pseudomyxoma extraperitonei (PE) is a rare finding. The most common cause is the rupture of a mucocele of the appendix into the retroperitoneum. PRESENTATION OF CASE: Here we report a case of a 52 years old female patient with a mass in the right abdomen and vague lower abdominal pain underwent resection of a extraperitoneal encapsulated mass. The histopathological examination revealed a mucinous pseudomyxoma with a low grade of differentiation. DISCUSSION: We report a case of pseudomyxoma extraperitonei with a review of literature. CONCLUSION: The treatment of pseudomyxoma differs substantially depending on whether it is intraperitoneal or extraperitoneal. The risk of recurrence is such that follow-up, based on a physical examination, CT scan and serum markers, is essential.

RESUMO

BACKGROUND: Anastomotic leakage (AL) is a dreaded major complication after colorectal surgery. There is no uniform definition of anastomotic dehiscence and leak. Over the years many risk factors have been identified (distance of anastomosis from anal verge, gender, BMI, ASA score) but none of these allows an early diagnosis of AL. The DUtch LeaKage (DULK) score, C reactive protein (CRP) and procalcitonin (PCT) have been identified as early predictors for anastomotic leakage starting from postoperative day (POD) 2-3. The study was designed to prospectively evaluate AL rates after colorectal resections, in order to give a definite answer to the need for clear risk factors, and testing the diagnostic yeld of DULK score and of laboratory markers. Methods and analysis. A prospective enrollment for all patients undergoing elective colorectal surgery with anastomosis carried out from September 2017 to September 2018 in 19 Italian surgical centers. OUTCOME MEASURES: preoperative risk factors of anastomotic leakage; operative parameters; leukocyte count, serum CRP, serum PCT and DULK score assessment on POD 2 and 3. Primary endpoint is AL; secondary endpoints are minor and major complications according to Clavien-Dindo classification; morbidity and mortality rates; readmission and reoperation rates, length of postoperative hospital stay (Retrospectively registered at ClinicalTrials.gov Identifier: NCT03560180, on June 18, 2018). Ethics. The ethics committee of the "Comitato Etico Regionale delle Marche - C.E.R.M." reviewed and approved this study protocol on September 7, 2017 (protocol no. 2017-0244-AS). All the participating centers submitted the protocol and obtained authorization from the local Institutional Review Board.

RESUMO

INTRODUCTION: Hepatic portal venous gas (HPVG) is a rare radiological finding in which gas enters the portal venous system and it is associated in case of necrotizing colitis with a mortality of 75%. We report a case of iatrogenic HPVG with a review of literature. PRESENTATION OF CASE: A 41 years old patient underwent total colectomy and ileal pouch- anal anastomosis with derivative ileostomy for a familiar adenomatous polyposis coli in June 2008. A stenosis of the pouch-anal anastomosis developed. The patient underwent several endoscopic dilations. A recurrence of the stenosis was observed. The patient underwent to several endoscopic procedure. After the last colonoscopy the patient showed a fever with abdominal pain. A CT scan showed little peri-anastomotic collections and massive hepatic portal venous gas. DISCUSSION: The management of HPVG varied from surgical intervention to non-operative procedure. The surgical approach it's reserved to clinically unstable patients or those with evidence of peritonitis or bowel perforation. Stable patients, like those with an HPVG consequence of an endoscopic procedure, can be treated with non- operative management. CONCLUSION: Our experience confirm that hepatic portal venous gas can be related to endoscopic procedure; thus, it can be managed on the basis of patient's general clinical conditions, and in selected cases it will disappear without therapeutic interventions with a good outcome.

RESUMO

INTRODUCTION: Laparoscopic cholecystectomy (LC) has become the "gold standard" for the treatment of symptomatic gallstones. However, this surgical technique increases the risk of bile duct injury and lost gallstones. Since over 90% of split gallstones never become symptomatic, they often present as incidental findings on CT-scans. Careful removal of as many stones as possible, intense irrigation and suction are recommended. It has been reported that 8.5% of lost gallstones will lead to a complication, most common are abscesses. PRESENTATION CASE: We report a case of spilled gallstones simulating peritoneal metastases on radiological investigations. Diagnosis was very difficult, not even an US-guided biopsy of the lesion was decisive. Only a diagnostic laparoscopy confirms the diagnosis. DISCUSSION: The reaction associated with lost gallstones can mimic other causes, such as soft tissue sarcoma, malignant lymphoma or, as in our case peritoneal carcinomatosis. CONCLUSION: Spilled gallstones are associated with uncommon, but significant complications, and even the diagnosis of such a condition can cause serious difficulties. Serious effort must be made to prevent gallbladder perforation, and accidental stone spillage should be promptly recognized and properly managed.

RESUMO

Anterior resection of the rectum and abdominoperineal resection with total mesorectal excision represent the standard surgical approach after preoperative chemoradiation in rectal cancer. Many clinical trials seem to validate laparoscopic approach, even if long-term outcome has not been still reported. Some authors recently focused their research on organ-saving surgery, either local excision or non-operative treatment. In this paper we present a brief revision of what rectal cancer treatment is reaching.

RESUMO

OBJECTIVE: Defunctioning stoma is a common surgical procedure, but the choice of stoma remains controversial. The preference for colostomy or ileostomy depends on the type of surgery and on the surgeon who performs the procedure. Stoma reversal is often performed a few weeks after colorectal resection but few studies have analysed the long-term complications of different types of stoma. This study aims to determine which type of stoma is associated with a lower rate of long-term complications. METHOD: A retrospective study of patients undergoing colorectal surgery from 1998 to 2004 with stoma creation after was conducted. Only patients followed up by our enterostomal therapist for a minimum of 3 months were included. Both emergency and elective procedures were considered. All stoma-related complications were recorded. Kruskal-Wallis and Mann-Whitney U-test were used for statistical analysis (Reviewer 2, n. 5). RESULTS: 132 patients were considered suitable for the analysis. Patients were divided into loop ileostomy (44), loop colostomy (77) and end colostomy (11) group. Mean age was 68 years. Mean follow up was 4 months (range: 3-23). The overall complication rate was 60%. The most common complication included dermatitis, parastomal hernia, leakage and stenosis. The stoma with the lowest complications rate was end colostomy (P = 0.026). Age <68 years was significantly associated with less complications (P = 0.01). Indication for surgery, emergency procedure, gender, morbidity and preoperative site were not significant factors. CONCLUSION: In this long term follow-up study, end colostomy and younger patients had a lower incidence of complications. A large prospective trial is needed to confirm our results.

RESUMO

AIMS: The histological modification produced by neoadjuvant chemoradiation on primary rectal cancer has been investigated by many authors, and a prognostic value of tumor regression grade (TRG) has been identified. Tumor regression grade on metastatic mesorectal lymphnodes has been never evaluated. The purpose of this study is to analyse the TRG on mesorectal lymphnodes (lymphnode regression grade, LRG) after preoperative chemoradiation in rectal cancer patients and to determine the correlation with TRG of primary tumor. METHODS: Surgical specimens from 35 patients who underwent chemoradiation were included. LRG on mesorectal lymphnodes was assessed by immunohistochemistry. Response to treatment was evaluated by a 5-point LRG based on the ratio of residual tumor to fibrosis. RESULTS: Complete pathologic response (LRG 1) was observed in 18 patients (51%). In 4 patients (11%) no regression was observed (LRG 5). In 4 cases only reactive lymphnodes were found. LRG on lymphnodes significantly correlated with TRG on primary tumor (p<0.05). CONCLUSIONS: Neoadjuvant chemoradiation determines a tumor regression on mesorectal lymphnodes as on primary tumor; further studies are needed to evaluate the prognostic value of LRG.

RESUMO

Patients who are undergoing endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for suspected pancreatic tumors frequently undergo endoscopic retrograde cholangiopancreatography (ERCP) for palliation of their symptoms. Performing EUS-FNA and ERCP in tandem may be cost-effective and may reduce procedure time, but the potential risks associated with this approach have not been clearly defined in the literature. We report two patients who underwent same-day therapeutic ERCP after transduodenal EUS-FNA for pancreatic tumors. Endoscopic biliary manipulation during ERCP aggravated an inadvertent and subclinical needle puncture injury to the bile duct sustained during the preceding EUS-FNA. This resulted in leakage of bile into the retroperitoneal space, and both patients required laparotomy and surgical drainage. Additional clinical evidence is needed to clarify these issues and to determine whether it would be prudent to perform therapeutic ERCP prior to diagnostic transduodenal EUS-FNA when these two procedures are planned as sequential or same-day procedures.

RESUMO

BACKGROUND: Neoadjuvant therapies have significantly improved local control and survival of patients with rectal cancer. Nevertheless, although a complete pathologic response can be achieved in 30% of cases, a transabdominal surgical resection is always required. This study aimed, for the first time, to test in the literature the feasibility of local excision combined with transanal endoscopic microsurgery (TEM) as a surgical option for patients treated with neoadjuvant chemoradiation. METHODS: Between July 1997 and December 2002, 30 patients with rectal cancer affected by an extraperitoneal tumor entered a protocol consisting of neoadjuvant chemoradiation followed by surgery. The surgical treatment, consisting of open surgery, local excision, or TEM, was planned according to the patient's clinical response after chemoradiation and distance from the anal verge. RESULTS: A significant clinical downstaging was observed in eight patients. Five of these patients underwent TEM, and three had local excision. Consequently, open surgery was performed for 22 patients. Histology showed six cases of complete pathologic response: three in the open surgery group and three in the transanal excision group. After a mean follow-up period of 47 months, the disease-free survival rate was 77% in the open surgery group and 100% in TEM or local excision group. CONCLUSIONS: The findings suggest the complementary feasibility of TEM and local excision after neoadjuvant chemoradiation. However, randomized trials are needed to confirm the oncologic safety of this approach.

RESUMO

PURPOSE: Local recurrence of rectal cancer occurs in a considerable group of patients who have undergone radical treatment for primary tumour. The treatment of choice is surgical resection but the prognosis remains poor, as a negative margin excision is possible in only a small subset of patients. A review of prognostic factors for locally recurrent rectal cancer (LRRC) after surgery is presented. METHODS: We systematically reviewed the literature for reports on prognostic factors after surgical excision of LRRC. These reports were identified through a review of the Medline database from 1982 to 2004. RESULTS: This review highlights the most important prognostic factors for LRRC patients treated with surgery. Data are grouped on the basis of the prognostic factors investigated. CONCLUSIONS: R0 resection seems to be the only reliable prognostic factor; however, symptoms, pre-operative CEA doubling time, performance status and pre-operative radiotherapy can help patient selection before surgery. The results of this review provide the basis for improved outcome, aiming to assess patients who would benefit from reoperation.

RESUMO

Pancreatic cancer is one of the most aggressive gastrointestinal cancer with less than 10% long-term survivors. The apoptotic pathway deregulation is a postulated mechanism of carcinogenesis of this tumour. The present study investigated the prognostic role of apoptosis and apoptosis-involved proteins in a series of surgically resected pancreatic cancer patients. All patients affected by pancreatic adenocarcinoma and treated with surgical resection from 1988 to 2003 were considered for the study. Patients' clinical data and pathological tumour features were recorded. Survivin and Cox-2 expression were evaluated by immunohistochemical staining. Apoptotic cells were identified using the TUNEL method. Tumour specimen of 67 resected patients was included in the study. By univariate analysis, survival was influenced by Survivin overexpression. The nuclear Survivin overexpression was associated with better prognosis (P = 0.0009), while its cytoplasmic overexpression resulted a negative prognostic factor (P = 0.0127). Also, the apoptotic index was a statistically significant prognostic factor in a univariate model (P = 0.0142). By a multivariate Cox regression analysis, both the nuclear (P = 0.002) and cytoplasmic (P = 0.040) Survivin overexpression maintained the prognostic statistical value. This is the first study reporting a statistical significant prognostic relevance of nuclear and cytoplasmic Survivin overexpression in pancreatic cancer. In particular, patients with high nuclear Survivin staining showed a longer survival, whereas patients with high cytoplasmic Survivin staining had a shorter overall survival.
