Identification and management of subvesical bile duct leakage after laparoscopic cholecystectomy: A systematic review

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.

TaTME approach as a rescue during a laparoscopic TME for high rectal cancer. A case report

•

There are several surgical approaches for patient with rectal cancer, depending on tumor stage and tumor distance from anal verge. Total mesorectal excision (TME) is the gold standard surgical technique for rectal tumors, reducing rectal cancer local recurrence.

•

Transanal total mesorectal excision (TaTME) has been described in rectal cancer treatment, especially in challenging patients with narrow pelvis, improving not only dissection but also the preservation of autonomic pelvic nerves and the achievement of a restorative procedure.

•

This case report aims to describe the possible use of TaTME procedure as a rescue also when this approach is not the first choice. In conclusion, we believe that, if performed by experienced surgeons, TaTME is safe and useful and could be used not in his conventional use.

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.

Transanal proctocolectomy and ileal pouch-anal anastomosis (TaIPAA) for ulcerative colitis: medium term functional outcomes in a single centre

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.

Topographic lymph node staging system shows prognostic superiority compared to the 8th edition of AJCC TNM in gastric cancer. A western monocentric experience

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.

The valdoni technique for bowel anastomosis. A rare complication

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.

Ectopic thoracic thyroid removed by uniportal VATS approach. A case report

•

VATS technique is minimally invasive and, moreover, it is characterized by a shorter recovery period, a minor blood loss and a shorter hospital stay.

•

We speak of “Ectopic thyroid gland” when a piece of thyroid tissue is placed at a certain distance from the second to fourth tracheal cartilages.

•

This case report aims at describing the successful extraction of a massive piece of ectopic thyroid from a young woman’s body, thanks to uniportal VATS.

Introduction

We speak of “Ectopic thyroid gland” when a piece of thyroid tissue is placed at a certain distance from the second to fourth tracheal cartilages.

Presentation of case

This case report focuses on a case of a hyperplastic cystic nodule of ectopic thyroid in a 30-year-old woman treated with uniportal video-assisted thoracic surgery (VATS). The patient, was admitted to Emergency Unit for abdominal pain and vomit, underwent a CT which highlighted a mass of significant dimension on the right side of the mediastinum, in contact with close structures. The lesion has been removed with an innovative mini-invasive technique, which is characterized, differently from traditional surgical approaches, by reduced loss of blood and time of hospitalization and, in addiction to that, an aesthetic small-dimensioned scar.

Discussion

VATS technique is minimally invasive and, moreover, it is characterized by a shorter recovery period, a minor blood loss and a shorter hospital stay. VATS has been advocated since 2010 for pulmonary resections, but today it is also performed for mediastinal intervention and a series of reports have demonstrated that it is feasible and safe.

Conclusion

The report aims at pointing out the possibility of undergoing this kind of surgery not only in case of pulmonary mass (on which the previous literature has focused) but also when mediastinum lesions occur, as in our case.

An omental mass. Any idea?

•

Pseudomyxoma peritonei, omental mass, review, abdominal pain, mucinous mass.

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.

Hepatic portal venous gas after colonoscopy: A case report and review

•

Here we reported a rare case of hepatic portal venous gas with a relevant review of literature.

•

Actually the mechanism of HPVG is still unknown.

•

The case present in literature are few and the mortality, generally caused by complications like necrotizing enterocolitis, is still high.

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.

Spilled gallstones simulating peritoneal carcinomatosis: A case report and literature review

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.
