Umbilical port metastasis from gallbladder carcinoma after laparoscopic cholecystectomy

Umbilical metastases: Real-world data shows abysmal outcome

Umbilical metastases form a clinical challenge, especially when they represent the first sign of malignant disease and the primary tumor is unknown. Our study aims to generate insight into the origin and timing of umbilical metastasis, as well as patient survival, using population‐based data. A nationwide review of pathology records of patients diagnosed with an umbilical metastasis between 1979 and 2015 was performed. Data was collected from the Nationwide Network and Registry of Histopathology and Cytopathology (PALGA) and the Netherlands Cancer Registry. Kaplan‐Meier analyses and log‐rank testing were used to estimate overall survival and a Cox proportional hazard model was used to determine multivariable hazard ratios. A total of 806 patients with an umbilical metastasis were included. There were 210 male (26.1%) and 596 female (73.9%) patients. Distribution of umbilical metastases was different between male and female patients due to the high incidence of umbilical metastases originating from the ovaries in females. They most frequently originated from the ovaries in female patients (38.8%) and from the colon in male patients (43.8%). In 18% of cases no primary tumor could be identified. Prognosis after diagnosis of an umbilical metastasis was dismal with a median survival of 7.9 months (95% confidence interval 6.7‐9.1). The origin of the primary tumor was an independent prognostic factor for overall survival. In conclusion, umbilical metastases relatively rare, mainly originating from intraabdominal primary tumors. Survival is dependent on the origin of the primary tumor and poor overall survival rates warrant early recognition.

What's new?

Umbilical metastases are a rare consequence of malignant disease that pose unique clinical challenges. Very little is known about these metastases, especially regarding incidence and survival. This population‐based analysis of more than 800 patients in the Netherlands shows that the distribution in umbilical metastases differs between males and females. In females, metastases most commonly originated from the ovaries, while in males, the colon was most common. Umbilical metastases, however, were linked to a variety of primary tumors and were frequently diagnosed synchronously with the primary tumor. While prognosis was poor overall, survival was influenced by primary tumor origin.

Adverse Outcomes After Bile Spillage in Incidental Gallbladder Cancers: A Population-based Study

OBJECTIVE

To determine the effect of bile spillage during cholecystectomy on oncological outcomes in incidental gallbladder cancers.

BACKGROUND

Gallbladder cancer (GBC) is rare, but lethal. Achieving complete resection offers the best chance of survival. About 30% of GBCs are discovered incidentally after cholecystectomy for benign pathology. There is an anecdotal association between peritoneal dissemination and bile spillage during the index cholecystectomy. However, no population-based studies are available that measure the consequences of bile spillage on patient outcomes.

METHODS

We conducted a retrospective cohort comparison of patients with incidental GBC. All cholecystectomies and cases of GBC in Alberta, Canada, from 2001 to 2015, were identified. GBCs discovered incidentally were included. Operative events leading to bile spillage were reviewed. Patient outcomes were compared between cases of bile spillage versus no contamination.

RESULTS

In all, 115,484 cholecystectomies were performed, and a detailed analysis was possible in 82 incidental GBC cases. In 55 cases (67%), there was bile spillage during the index cholecystectomy. Peritoneal carcinomatosis occurred more frequently in those with bile spillage (24% vs 4%; P = 0.0287). Patients with bile spillage were less likely to undergo a radical re-resection (25% vs 56%; P = 0.0131) and were less likely to achieve an R0 resection margin [odds ratio 0.19, 95% confidence interval (CI) 0.06-0.55]. On Cox regression modeling, bile spillage was an independent predictor of shorter disease-free survival (hazard ratio 1.99, 95% CI 1.07-3.67).

CONCLUSION

For incidentally discovered GBC, bile spillage at the time of index cholecystectomy has measureable adverse consequences on patient outcomes. Early involvement of a hepatobiliary specialist is recommended where concerning features for GBC exist.

Sister Mary Joseph's nodule as a metastasis of gallbladder carcinoma

Umbilical metastasis, alias Sister Mary Joseph's nodule, is a rare clinical phenomenon. It indicates neoplasm of inner organs mostly located in the gastrointestinum or the pelvis. However, in approximately 15-30% the primary tumor remains occult. In most cases Sister Joseph's nodule appears as an early and sometimes the only symptom of the malignoma. Here we report on an umbilical metastasis of a gallbladder carcinoma with subsequent manifestation of other tumor complications such as extensive thrombosis of arm veins.

Port-site metastasis following laparoscopic cholecystectomy: a review of the literature and a case report

Port-site metastasis following laparoscopic cholecystectomy with unsuspected gallbladder carcinoma is a serious problem. We reviewed 45 such cases reported in the English literature to date, and add another case which occurred in a 72-year-old female 13 months after a laparoscopic cholecystectomy for gallstones, who also had an unapparent gallbladder carcinoma. Pre-operative diagnosis of gallbladder carcinoma is possible in less than 10% of cases, with a high index of suspicion. If detected during laparoscopy early conversion to open procedure is recommended. If diagnosed later, however, to contemplate further radical operation depending on histopathology would be unwise as a universal approach, because of increased associated morbidity and mortality. The prospect of cure is also very unrealistic in this condition.

Possible first report of distant peritoneal metastases from a nodal mesenteric lymphoma after laparoscopic inguinal hernia repair

Laparoscopic surgery has gained wide acceptance. However, there is still debate as to its role in assessment and staging of gastrointestinal malignancies(1)since it may promote dissemination of cancer cells.(2)We report the first case of a low-grade mesenteric nodal lymphoma for laparoscopic hernia repair, complicated by distant implants both on the peritoneum and wall mesh.

Recurrent gallbladder carcinoma along laparoscopic cholecystectomy port tracks: CT demonstration

PURPOSE

To describe the computed tomographic (CT) appearance of recurrent gallbladder carcinoma along port tracks after laparoscopic cholecystectomy and to assess the effect of recurrence on patient care.

MATERIALS AND METHODS

Seventeen abdominal CT scans in 16 of 19 consecutive patients who underwent hepatic resection for gallbladder carcinoma diagnosed at laparoscopic cholecystectomy were reviewed retrospectively. Medical records were reviewed to determine the clinical effect of tumor recurrence along a port track.

RESULTS

CT revealed 12 tumor recurrences along laparoscopic port tracks in six (32%) patients (mean, two recurrences per patient; range, one to four per patient). Eight (67%) CT-depicted recurrences appeared homogeneous, and nine (75%) directly involved subjacent omental fat. The mass was the only site of recurrence at CT in two (33%) patients. The presence of an abdominal wall tumor recurrence affected patient care in four (67%) of six patients. Histopathologic examination results confirmed recurrent tumor in all five (100%) patients who underwent biopsy.

CONCLUSION

Tumor recurrence along port tracks is a potential complication of laparoscopic cholecystectomy when gallbladder carcinoma is present, even after subsequent hepatic resection is performed for attempted cure. Recurrences appear as a new or enlarging abdominal wall mass, often involving subjacent omental fat, and may be the only site of recurrent disease at CT. Demonstration of abdominal wall tumor recurrence affects patient care.
