An International Registry of Peritoneal Carcinomatosis from Appendiceal Goblet Cell Carcinoma Treated with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy

PURPOSE

Peritoneal carcinomatosis from appendiceal goblet cell carcinoma (A-GCC) is a rare and aggressive form of appendiceal tumor. Cytoreductive surgery (CRS) and hyperthermic intra peritoneal chemotherapy (HIPEC) was reported as an interesting alternative regarding survival compared to surgery without HIPEC and/or systemic chemotherapy. Our aim was to evaluate the impact of CRS and HIPEC for patients presenting A-GCC through an international registry.

METHODS

A prospective multicenter international database was retrospectively searched to identify all patients with A-GCC tumor and peritoneal metastases who underwent CRS and HIPEC through the Peritoneal Surface Oncology Group International (PSOGI). The post-operative complications, long-term results, and principal prognostic factors were analyzed.

RESULTS

The analysis included 83 patients. After a median follow-up of 47 months, the median overall survival (OS) was 34.6 months. The 3- and 5-year OS was 48.5% and 35.7%, respectively. Patients who underwent complete macroscopic CRS had a significantly better survival than those treated with incomplete CRS. The 5-year OS was 44% and 0% for patients who underwent complete, and incomplete CRS, respectively (HR 9.65, p < 0.001). Lymph node involvement and preoperative chemotherapy were also predictive of a worse prognosis. There were 3 postoperative deaths, and 30% of the patients had major complications.

CONCLUSION

CRS and HIPEC may increase long-term survival in selected patients with peritoneal metastases of A-GCC origin, especially when complete CRS is achieved. Ideally, randomized control trials or more retrospective data are needed to confirm CRS and HIPEC as the gold standard in this pathology.

Management of abdominal compartment syndrome in acute pancreatitis

Abdominal compartment syndrome (ACS), defined by the presence of increased intra-abdominal pressure>20mmHg in association with failure of at least one organ system, is a common and feared complication that may occur in the early phase of severe acute pancreatitis (AP). This complication can lead to patient death in the very short term. The goal of this review is to provide the surgeon and intensivist with objective information to help them in their decision-making. In the early phase of severe AP, it is essential to monitor intra-vesical pressure (iVP) to allow early diagnosis of intra-abdominal hypertension or ACS. The treatment of ACS is both medical and surgical requiring close collaboration between the surgical and resuscitation teams. Medical treatment includes vascular volume repletion, prokinetic agents, effective curarization and percutaneous drainage of large-volume ascites. If uncontrolled respiratory or cardiac failure develops or if maximum medical treatment fails, most teams favor performing an emergency xipho-pubic decompression laparotomy with laparostomy. This procedure follows the principles of abbreviated laparotomy as described for abdominal trauma.

Colon sparing resection versus extended colectomy for left-sided obstructing colon cancer with caecal ischaemia or perforation: a nationwide study from the French Surgical Association

AIM

It is not known whether patients with obstructive left colon cancer (OLCC) with caecal ischaemia or diastatic perforation (defined as a blowout of the caecal wall related to colonic overdistension) should undergo a (sub)total colectomy (STC) or an ileo-caecal resection with double-barrelled ileo-colostomy. We aimed to compare the results of these two strategies.

METHOD

From 2000 to 2015, 1220 patients with OLCC underwent surgery by clinicians who were members of the French Surgical Association. Of these cases, 201 (16%) were found to have caecal ischaemia or diastatic perforation intra-operatively: 174 patients (87%) underwent a STC (extended colectomy group) and 27 (13%) an ileo-caecal resection with double-end stoma (colon-sparing group). Outcomes were compared retrospectively.

RESULTS

In the extended colectomy group, 95 patients (55%) had primary anastomosis and 79 (45%) had a STC with an end ileostomy. In the colon-sparing group, 10 patients (37%) had simultaneous resection of their primary tumour with segmental colectomy and an anastomosis which was protected by a double-barrelled ileo-colostomy. The demographic data for the two groups were comparable. Median operative time was longer in the STC group (P = 0.0044). There was a decrease in postoperative mortality (7% vs 12%, P = 0.75) and overall morbidity (56% vs 67%, P = 0.37) including surgical (30% vs 40%, P = 0.29) and severe complications (17% vs 27%, P = 0.29) in the colon-sparing group, although these differences did not reach statistical significance. Cumulative morbidity included all surgical stages and the rate of permanent stoma was 66% and 37%, respectively, with no significant difference between the two groups. Overall survival and disease-free survival were similar between the two groups.

CONCLUSION

The colon-sparing strategy may represent a valid and safe alternative to STC in OLCC patients with caecal ischaemia or diastatic perforation.

Impact of cirrhosis in patients undergoing laparoscopic liver resection in a nationwide multicentre survey

BACKGROUND

The aim was to analyse the impact of cirrhosis on short-term outcomes after laparoscopic liver resection (LLR) in a multicentre national cohort study.

METHODS

This retrospective study included all patients undergoing LLR in 27 centres between 2000 and 2017. Cirrhosis was defined as F4 fibrosis on pathological examination. Short-term outcomes of patients with and without liver cirrhosis were compared after propensity score matching by centre volume, demographic and tumour characteristics, and extent of resection.

RESULTS

Among 3150 patients included, LLR was performed in 774 patients with (24·6 per cent) and 2376 (75·4 per cent) without cirrhosis. Severe complication and mortality rates in patients with cirrhosis were 10·6 and 2·6 per cent respectively. Posthepatectomy liver failure (PHLF) developed in 3·6 per cent of patients with cirrhosis and was the major cause of death (11 of 20 patients). After matching, patients with cirrhosis tended to have higher rates of severe complications (odds ratio (OR) 1·74, 95 per cent c.i. 0·92 to 3·41; P = 0·096) and PHLF (OR 7·13, 0·91 to 323·10; P = 0·068) than those without cirrhosis. They also had a higher risk of death (OR 5·13, 1·08 to 48·61; P = 0·039). Rates of cardiorespiratory complications (P = 0·338), bile leakage (P = 0·286) and reoperation (P = 0·352) were similar in the two groups. Patients with cirrhosis had a longer hospital stay than those without (11 versus 8 days; P = 0·018). Centre expertise was an independent protective factor against PHLF in patients with cirrhosis (OR 0·33, 0·14 to 0·76; P = 0·010).

CONCLUSION

Underlying cirrhosis remains an independent risk factor for impaired outcomes in patients undergoing LLR, even in expert centres.

Thirty-day mortality after emergency surgery for obstructing colon cancer: survey and dedicated score from the French Surgical Association

AIM

The aim was to define risk factors for postoperative mortality in patients undergoing emergency surgery for obstructing colon cancer (OCC) and to propose a dedicated score.

METHOD

From 2000 to 2015, 2325 patients were treated for OCC in French surgical centres by members of the French National Surgical Association. A multivariate analysis was performed for variables with P value ≤ 0.20 in the univariate analysis for 30-day mortality. Predictive performance was assessed by the area under the receiver operating characteristic curve.

RESULTS

A total of 1983 patients were included. Thirty-day postoperative mortality was 7%. Multivariate analysis found five significant independent risk factors: age ≥ 75 (P = 0.013), American Society of Anesthesiologists (ASA) score ≥ III (P = 0.027), pulmonary comorbidity (P = 0.0002), right-sided cancer (P = 0.047) and haemodynamic failure (P < 0.0001). The odds ratio for risk of postoperative death was 3.42 with one factor, 5.80 with two factors, 15.73 with three factors, 29.23 with four factors and 77.25 with five factors. The discriminating capacity in predicting 30-day postoperative mortality was 0.80.

CONCLUSION

Thirty-day postoperative mortality after emergency surgery for OCC is correlated with age, ASA score, pulmonary comorbidity, site of tumour and haemodynamic failure, with a specific score ranging from 0 to 5.

Relevance of early CT scan diagnosis of blunt diaphragmatic injury: A retrospective analysis from the Northern French Alps Emergency Network

INTRODUCTION

Diaphragmatic rupture following blunt trauma occurs rarely. Classically described after high-velocity accidents, ruptures are often associated with multiple organ injuries. The diagnosis is sometimes difficult. The goal of this study was to analyze and to discuss the modalities of early radiologic diagnosis and management of these injuries.

PATIENTS AND METHODS

This multicenter retrospective study included patients seen between 2009 and 2017 within the Northern Alpine Emergency Network [REseau Nord Alpin des Urgences (RENAU)]. Clinical, radiologic and surgical data from all patients sustaining blunt diaphragmatic rupture were studied.

RESULTS

Thirty-one patients (18 men and 13 women), median age 44, were included. The principle mechanism of injury was road or traffic accidents for 22 patients. Diaphragmatic rupture occurred on the left side in 23 patients. Diagnosis was delayed in two patients, at 11 days and three months after the initial accident. Chest X-rays were diagnostic in 18 of 29 patients. CT scan was the reference investigation since it was performed in all patients and confirmed the diagnosis in 26 instances. Repair was surgical via a midline laparotomy in 27 patients, via laparoscopy in three, and via thoracoscopy in one. Three patients died.

CONCLUSION

At urgent surgical exploration in the unstable blunt trauma patient, the surgeon should keep in mind the relatively poor diagnostic performance of chest X-rays. Accurate diagnosis relies on routine inspection of the diaphragmatic cupolas. In the stable trauma victim, contrast-enhanced abdomino-thoracic CT with reconstruction can lead to early diagnosis, which allows for repair under optimal conditions, whether by laparotomy, laparoscopy or thoracoscopy, according to local conditions and expertise.

Multicentre study of laparoscopic or open assessment of the peritoneal cancer index (BIG-RENAPE)

Background

The peritoneal cancer index (PCI) is a comparative prognostic factor for colorectal peritoneal metastasis (CRPM). The ability of laparoscopy to determine the PCI in consideration of cytoreductive surgery remains undetermined, and this study was designed to compare it with laparotomy.

Methods

A prospective multicentre study was conducted for patients with no known CRPM, but at risk of peritoneal disease. Surgery began with laparoscopic exploration followed by open exploration to determine the PCI. Concordance between laparoscopic and open assessment was evaluated for the diagnosis of CRPM and for the PCI.

Results

Among 50 patients evaluated, CRPM recurrence was found in 29 (58 per cent) and 34 (68 per cent) at laparoscopic and open surgery respectively. Laparoscopy was feasible in 88 per cent (44 of 50) and deemed satisfactory by the surgeon in 52 per cent (26 of 50). Among the 25 evaluable patients with satisfactory laparoscopy, there was concordance of 96 per cent (24 of 25 patients) and 38 per cent (10 of 25) for laparoscopic and open assessment of CRPM and the PCI respectively. Where there were discrepancies, it was laparoscopy that underestimated the PCI.

Conclusion

Laparoscopy may underestimate the extent of CRPM.

Retrospective study of thoracotomy performed in a French level 1-trauma center

OBJECTIVE

Resuscitative thoracotomy, a potentially life-saving procedure, is used exceptionally, and essentially for penetrating trauma. Most of the available literature is American while reports from Europe are sparse. We report our experience in a French level 1-trauma center.

MATERIAL AND METHODS

Patient records (patient age, gender, mechanism of injury, indication for emergency thoracotomy, anatomic injuries, interventions and survival) for all patients who underwent emergency thoracotomy between January 2005 and December 2015 were analyzed.

RESULTS

Twenty-two patients (19 males) underwent emergency thoracotomy. Median age was 27.5 (12-67) years. Twelve were performed for blunt trauma (55%) and 10 for penetrating injuries (45%). Thirteen patients presented with cardiac arrest, while nine had deep and refractory hypotension. Overall, survival was 32% (n=7). There were no survivors in the blunt trauma group while seven of ten with penetrating injuries survived. All patients presenting with cardiac arrest died.

CONCLUSION

The survival rate in this French retrospective study was in accordance with the literature.

Management of pancreatic trauma

INTRODUCTION

Pancreatic trauma (PT) is associated with high morbidity and mortality; the therapeutic options remain debated.

MATERIAL AND METHODS

Retrospective study of PT treated in the University Hospital of Grenoble over a 22-year span. The decision for initial laparotomy depended on hemodynamic status as well as on associated lesions. Main pancreatic duct lesions were always searched for. PT lesions were graded according to the AAST classification.

RESULTS

Of a total of 46 PT, 34 were grades II or I. Hemodynamic instability led to immediate laparotomy in 18 patients, for whom treatment was always drainage of the pancreatic bed; morbidity was 30%. Eight patients had grade III injuries, six of whom underwent immediate operation: three underwent splenopancreatectomy without any major complications while the other three who had simple drainage required re-operation for peritonitis, with one death related to pancreatic complications. Four patients had grades IV or V PT: two pancreatoduodenectomies were performed, with no major complication, while one patient underwent duodenal reconstruction with pancreatic drainage, complicated by pancreatic and duodenal fistula requiring a hospital stay of two months. The post-trauma course was complicated for all patients with main pancreatic duct involvement. Our outcomes were similar to those found in the literature.

CONCLUSION

In patients with distal PT and main pancreatic duct involvement, simple drainage is associated with high morbidity and mortality. For proximal PT, the therapeutic options of drainage versus pancreatoduodenectomy must be weighed; pancreatoduodenectomy may be unavoidable when the duodenum is injured as well. Two-stage (resection first, reconstruction later) could be an effective alternative in the emergency setting when there are other associated traumatic lesions.

Rectal perforation with life-threatening peritonitis following stapled haemorrhoidopexy

BACKGROUND

Stapled haemorrhoidopexy is a well recognized alternative to haemorrhoidectomy, and is associated with reduced pain and earlier return to normal activity. This paper reports all published cases of life-threatening sepsis following stapled haemorrhoidopexy, identifies causative factors and makes recommendations.

METHODS

A systematic review of the literature was performed by searching the major electronic databases. All relevant references were reviewed for possible inclusion. All references of the relevant articles were screened for any further articles that were not identified in the initial search.

RESULTS

From 2000 to the present, 29 articles reporting complications in 40 patients were identified. Thirty-five patients underwent laparotomy with faecal diversion and a further patient was treated by low anterior resection. A specific complication was rectal perforation with peritonitis. Factors that led to life-threatening sepsis were identified in 30 patients. Despite surgical treatment and resuscitation, there were four deaths.

CONCLUSION

Severe sepsis can complicate stapled haemorrhoidopexy. Rectal perforation and peritonitis are a particular risk of this technique and the associated mortality rate is high.
