RESUMO
BACKGROUND: A newly emerging approach "caudal to cranial" with complete mesenteric excision (CME) has recently been proposed for right colectomy in patients with right colon cancer. To date, only a few studies about this approach have appeared. Our study aims to investigate the safety and efficacy of this new technique. METHODS: A systematic review of the literature was conducted to evaluate the evidence regarding short- and long-term outcomes after the caudal-to-cranial approach (CCA). Methodological Index for Non-Randomized Studies was used to evaluate methodological quality. The risk of bias was assessed using Robvis tool. Meta-analyses have been conducted for the outcomes of studies comparing CCA with other techniques. RESULTS: We found six studies from 2017 to 2021 with a total of 594 patients. The postoperative complications and oncological outcomes were acceptable. Two studies comparing CCA to medial-to-lateral approach were included in the meta-analysis. No differences were found between the techniques regarding to operative time, length of hospital stay, overall morbidity, and number of lymph nodes. CONCLUSION: Although the interpretation of our findings may be restrained by methodological limitations, risk of bias, and the absence of well-designed randomized controlled trials, CCA with CME in right-sided colon cancer may be a feasible and safe procedure.

INTRODUCTION: To date, all meta-analyses on oral antibiotic prophylaxis (OA) and mechanical bowel preparation (MBP) in colorectal surgery have included results of both open and minimally invasive approaches. Mixing both procedures may lead to false conclusions. The aim of the study was to assess the available evidence of mechanical and oral antibiotic bowel preparation in reducing the incidence of surgical site infection (SSI) and other complications following minimally invasive elective colorectal surgery. METHODS: We searched PubMed, Science Direct, Google Scholar and Cochrane Library from 2000 to May 1, 2022. Comparative randomized and non-randomized studies were included. We reviewed the use of oral OA, MBP and combinations of these treatments. The methodological quality of the included studies was assessed using the Rob v2 and Robins-I tools. RESULTS: We included 18 studies (7 randomized controlled trials and 11 cohort studies). Meta-analysis of the included studies showed that the combination of MBP + OA was associated with a significant reduction in SSI, AL and overall morbidity compared with the other options no preparation, MBP only and OA only. CONCLUSION: Adding OA with MBP has a positive impact in reducing the incidence of SSI, AL and overall morbidity after minimally invasive colorectal surgery. Therefore, the combination of OA and MBP should be encouraged in this selected group of patients undergoing minimally invasive surgery.

Digestive fistula on mesh is an exceptional and late complication of hernioplasty. The type of mesh and its position are often implicated in its occurrence. Clinical presentation is multiform. Morphological examinations are essential to confirm the diagnosis, and the curative treatment remains surgical.
RESUMO
PURPOSE: The aim of this systematic review and meta-analysis was to define clinical indicator that predicts mediastinal lymph nodes metastasis (MLNM) in patients with Esophagogastric junction cancer (EGJC) to select patient population requiring esophagectomy. METHODS: A systematic and electronic search of several electronic databases was performed up to August 2020. Studies containing information on risk factors for MLNM in patients diagnosed with EJGC and who underwent curative surgery were included. RESULTS: Two predictors, including undifferentiated type (OR = 1.82, 95% CI = 1.07-3.10, p = 0.03) and esophageal invasion length (EIL) (OR = 10.95, 95% CI = 6.37-18.82, p < 0.00001) were identified as significant predictors for the risk of MLNM. CONCLUSION: Knowledge of the associations of these clinicopathological features with MLNM can be useful in determining operative strategy for EGJC.

BACKGROUND: Given the risk of surgical site infection (SSI), the use of mesh in contaminated ventral hernia repair (VHR) is not standardized and still a clinical dilemma. This meta-analysis aimed to assess whether mesh use increased the risk of SSI in patients following VHR in contaminated field. METHODS: We performed a systematic review of published literature. Studies comparing the mesh repair and anatomic repair, the use of mesh in different Center for Disease Control and Prevention (CDC) wound classes and mesh repair with synthetic mesh or other type of meshes to treat complicated and contaminated VHR were considered for analysis. The main outcome was SSI incidence. RESULTS: Six studies compared mesh and suture repairs. No significant difference in SSI incidence was observed between patients with complicated VHR in the mesh and suture repair groups.Five studies analyzed mesh repair in patients by field contamination level. There was no significant difference between the use of mesh in clean-contaminated, contaminated and dirty field versus clean wound class. Moreover, there was no significant difference between the use of mesh in clean-contaminated and contaminated cases.Four studies compared mesh repair technique with synthetic mesh or other type of meshes were included. The incidence of SSI was significantly lower in the synthetic mesh group. CONCLUSIONS: The use of mesh repair in the management of complicated VHR compared to suture repair is not associated with an increased incidence of SSI even in potentially contaminated fields.
RESUMO
Hydatidosis is a widespread anthropozoonosis. It can affect almost any part of the body, but it occurs most commonly in the liver (75%) and the lungs (15%). Its occurrence in female genital tract, especially the uterus, is very rare. Diagnosing hydatid disease at these unusual locations can be difficult. Hereby, we report two cases of primary hydatid cyst of the uterus. The first case is that of a 62-year-old woman, G7P5A2, who presented with an eight-month history of chronic pelvic pain. Clinical examination and radiological explorations revealed the presence of a uterine fibroid and a serous cystadenoma of the left ovary. She underwent a hysterectomy and a bilateral adnexectomy. Anatomopathological examination concluded that a serous cystadenoma of the left ovary was a calcified subserous hydatid cyst of the uterine fundus. The second case is that of a 69-year-old woman, G6P4A2, who consulted for chronic pelvic pain that had been evolving for 3 months. The clinical examination and radiological explorations doubted a hydatid cyst of the uterus, with a positive hydatid serology. She underwent a resection of the salient dome. The anatomopathological examination was in favor of a hydatid cyst of the uterus. Hydatid disease is endemic in Tunisia. The pelvic region is rarely affected with an incidence ranging from 0.3 to 0.9%, 80% of which involves the genitals. The uterus is more rarely affected than the ovaries. Most often, it is a contamination secondary to the intra-abdominal rupture of a hydatid cyst of the liver. However, primary uterine hydatid cysts have been reported. Surgery is the Gold Standard for the treatment of uterine hydatid cysts. Exploration of the abdominal cavity is essential in the search for other localizations, particularly hepatic. Postoperative medical treatment with Albendazole can be discussed. The ideal approach to deal with this public health concern is to emphasize the need for improved preventive measures. Modern imaging techniques have significantly improved the detection rates of hydatid cysts in atypical localizations. Indeed, the preoperative diagnosis of uterine hydatidosis requires a meticulous approach which is necessary to initiate an adequate treatment and thus guarantee a better management of the patient.
RESUMO
BACKGROUND: Anorectal melanoma is a rare but highly lethal malignancy. Clinical symptoms are non-specific and treatment is still debated. AIM: The aim of this study was to report a case concerning diagnostic and management of Anorectal melanoma. CASE: A 66-year-old man was admitted in our surgical unit with a 3- month history of pain and rectal bleeding. Rectal examination revealed a tender mass arising from the 5 o'clock position of the anal canal that bled on touch. A provisional diagnosis of rectal polyp was made and it was removed by local excision under general anaesthesia. Histopathologic examination reported it as an anorectal malignant melanoma. The postoperative course was uneventful. Extension staging showed a 15 mm nodule on the left lung. The patient underwent a metastasectomy of the left lung. No adjuvant therapy was given. He died one year later. CONCLUSION: With this case we want to illustrate that malignant melanoma can be difficult to diagnose, as patients have non-specific symptoms and histology may be misleading. Surgery remains the mainstay of treatment. Wide local excision combined with adjuvant oco-regional radiotherapy should be preferred when technically feasible. Abdominoperineal resection has to be done only in the case of large tumors or when the anal sphincter is involved. Overall 5-year survival is less than 20%. It's correlated to extension of disease regardless of initial surgical therapy.

This systematic review was designed to provide "evidence-based" answers to identify the best treatment for a complicated hydatid cyst of the liver and the appropriate management of disseminated cystic echinococcosis. An extensive electronic search of the relevant literature was performed using Medline and the Cochrane Library. This systematic review enabled us make to determine the best treatment options for the following conditions. Liver hydatid cysts ruptured into the biliary tract: Common bile duct exploration should be conducted using intraoperative cholangiography and choledoscopy. When the biliary tract is cleared of all cystic content, T-tube drainage should be sufficient. The principal difficulty concerned the management of the large biliocystic fistula: suture or internal transfistulary drainage or fistulization. Medical treatment is indicated in association with surgery for 3 months postoperatively. During the preoperative period, endoscopic retrograde cholangiopancreatography (ERCP) combined with preoperative endoscopic sphincterotomy (ES) may decrease the incidence of postoperative external fistula. Liver hydatid cysts involving the thorax: An abdominal approach is mandatory when common bile duct drainage is required, and it may be sufficient to treat a direct rupture into bronchi. An acute abdomen, owing to Liver hydatid cysts ruptured into peritoneum, requires an emergent operation. Medical treatment should be associated. Cystic echinococcosis of the lung: Surgery is still the main therapeutic option to remove the cyst, suture bronchial fistula if necessary, followed by capitonnage. Osseous cystic echinococcosis: Wide surgical excision is recommended. Cystic echinococcosis of the heart: Cystopericystectomy is the "gold standard" procedure but is sometimes unsuitable for particular sites. Cystic echinococcosis of the kidney: Cystectomy with pericystectomy is feasible in 75% of cases; nephrectomy must be reserved for destroyed kidney. Multiple associated cystic echinococcosis locations: Complicated cysts should be treated with high priority. In case of several cysts in the liver, spleen, and peritoneum, removal of all cysts in the same intervention is indicated when there is no threat to the life of the patient. Otherwise, a planned reoperation should be considered.

BACKGROUND: Gastrointestinal stromal tumours are a large category of primary no epithelial neoplasms of the digestive tract. The localization of stromal tumours in the ampulla of Vater (STAV) is very rare. AIM: The aim of this study was to describe clinical, endoscopic and therapeutic particularities of STAV. METHODS: We reported a new case and we carried out an extensive electronic search for the relevant literature using Medline. Key words used were "ampulla of Vater" and "Gastrointestinal stromal tumor" and "CD 117". With our case, we collected seven other cases in the literature. RESULTS: The analysis of the sample of these eight cases leads us to propose the following conclusions. STAV is a tumor of adult after the age of fifty. There is no specific symptomatology. Gastroduodenal endoscopy with biopsies and immunoassaying allows positive preoperative diagnosis in the 5 cases. Treatment should be duodenopancreatectomy since the tumor is often malignant (5 cases).

BACKGROUND: Descending necrotizing mediastinitis (DNM) following an oropharyngeal infection is a rare disease with a rapid course and a mortality rate of up to 40%. The aim of this study, is to outline the diagnosis and the appropriate treatment of DNM. METHODS: A retrospective study (1986-2007) of patients with DNM was made. Only patients with cervical cellulitis associated with DNM were included. RESULTS: Eight men and two women with an average age of 43 years were treated. Five had diabetes. The average for diagnosis and treatment was eight days. In eight cases, we found a dental origin and in two cases a pharyngeal origin. The diagnosis of DNM was made thanks to cervico thoracic CT scan in six cases. In the others patients, they had at presentation clinical and radiological evidence of mediastinal diffusion. All patients were treated by broad spectrum antibiotherapy. All had cervical drainage. Mediastinal drainage was made by cervical approach in 2 two cases and via a right thoracotomy in eight cases. Eight patients died. CONCLUSION: Odontogenic DNM is a rare disease with rapid course. Clinical diagnosis is difficult and early recognition with a low thresold for CT scanning is essential. CT is also useful for the treatment and in the post operative assessment. All affected tissue plane must be debrided. Surgical management and mediastinal drainage remain controversial about the indication of thoracotomy.

INTRODUCTION: Intussusception through an ileostomy is one of the rarest complications of stomas. In this study we report a case and a brief update of the literature to focus on the clinical level of this pathology and the therapeutic attitudes. PRESENTATION OF CASE: a 44-year-old man who underwent a small bowel resection with double stoma for tuberculosis peritonitis presented with stomatal prolapse. On examination of the stoma, small bowel mucosa appeared to have evident rather than serosa. The patient had an elective reduction of the proximal stoma under anesthesia. CONCLUSION: A review of the literature shows that Intussusception through an ileostomy can occur at any time after the first surgery. The cause is still unclear. Urgent conservative surgical management based on manual reduction should be preferred.
RESUMO
Laparoscopic cholecystecmy is the preferred method for removing the Gall bladder. The most frequent intra-operative complications are by for related to the biliary tract: wounds, section. From September 1995 to August 2001, the authors have realized 1570 cases of laparoscopic cholecystectomy. There were 3 lesions of the common bile duct. Most of those complications are directly proportional to the operators experience. Their prevention depends on a perfect technics, understanding of the mechanisms and no hesitation in converting to conventional laparotomy whenever difficulties are encountered.

Treatment of hydatid cyst of the liver ranges from surgical intervention (conventional or laparoscopic approach) to percutaneous drainage and to medical therapy. The aim of this systematic review was to provide "evidence-based" answers to the following questions: Should chemotherapy be used alone or in association with surgery? What is the best surgical technique? When is the percutaneous aspiration injection and reaspiration technique (PAIR) indicated? An extensive electronic search of the relevant literature without limiting it to the English language was carried out using MEDLINE and the Cochrane Library. Key words used for the final search were "hydatid cyst," "liver," "treatment," "meta analysis," "randomized controlled trial," "prospective study," "retrospective study." All relevant studies reporting the assessment of one modality of treatment or a comparison of two or several therapeutic methods to treat hydatid cyst of the liver and published in a peer-reviewed journal were considered for analysis. This systematic review allowed us to conclude that chemotherapy is not the ideal treatment for uncomplicated hydatid cysts of the liver when used alone (level II evidence, grade B recommendation). The level of evidence was too low to help decide between radical or conservative treatment (level IV evidence, grade C recommendation). Omentoplasty associated with radical or conservative treatment is efficient in preventing deep abscesses (level II evidence, grade A recommendation). The laparoscopic approach is safe (level IV evidence, grade C recommendation). Drug treatment associated with surgery (level II evidence, grade C recommendation) requires further studies. Percutaneous drainage associated with albendazole therapy is safe and efficient in selected patients (level II evidence, grade B recommendation). The level of evidence is low concerning treatment of complicated cysts.
