[A man with abdominal pain after esophageal surgery]. / Een man met buikpijn na een slokdarmoperatie.

A 66-year-old man is evaluated in the Emergency Department for abdominal pain and vomiting since 2 days. Medical history showed esophageal resection because of an esophageal carcinoma. On physical examination there was tenderness of the right hemi-abdomen. A CT-angiography-chest/abdomen proved intrathoracically located small intestines with signs of ischemia.

Resection of hepatic and pulmonary metastasis from metastatic esophageal and gastric cancer: a nationwide study.

The standard of care for gastroesophageal cancer patients with hepatic or pulmonary metastases is best supportive care or palliative chemotherapy. Occasionally, patients can be selected for curative treatment instead. This study aimed to evaluate patients who underwent a resection of hepatic or pulmonary metastasis with curative intent. The Dutch national registry for histo- and cytopathology was used to identify these patients. Data were retrieved from the individual patient files. Kaplan-Meier survival analysis was performed. Between 1991 and 2016, 32,057 patients received a gastrectomy or esophagectomy for gastroesophageal cancer in the Netherlands. Of these patients, 34 selected patients received a resection of hepatic metastasis (n = 19) or pulmonary metastasis (n = 15) in 21 different hospitals. Only 4 patients received neoadjuvant therapy before metastasectomy. The majority of patients had solitary, metachronous metastases. After metastasectomy, grade 3 (Clavien-Dindo) complications occurred in 7 patients and mortality in 1 patient. After resection of hepatic metastases, the median potential follow-up time was 54 months. Median overall survival (OS) was 28 months and the 1-, 3-, and 5- year OS was 84%, 41%, and 31%, respectively. After pulmonary metastases resection, the median potential follow-up time was 80 months. The median OS was not reached and the 1-, 3-, and 5- year OS was 67%, 53%, and 53%, respectively. In selected patients with gastroesophageal cancer with hepatic or pulmonary metastases, metastasectomy was performed with limited morbidity and mortality and offered a 5-year OS of 31-53%. Further prospective studies are required.

Omitting Postoperative Wound Drainage After Mastectomy With Skin-Flap Quilting.

BACKGROUND: Seroma is the most frequent complication after mastectomy (ME) and axillary lymph node dissection (ALND). The quilting suture technique, in which skin flaps are sutured to the underlying muscle, was previously investigated and found to reduce seroma incidence after ME and ALND. This study aimed to investigate whether postoperative wound drainage can safely be omitted when quilting sutures are applied. METHODS: Two groups with a total of 251 consecutive patients who underwent ME, ALND, or both were retrospectively compared. The first group underwent quilting sutures with wound vacuum drainage, and the second group underwent quilting sutures without wound drainage. The primary outcome was the incidence of postoperative clinically significant seroma (CSS). The secondary outcomes were the incidence of postoperative infection, bleeding complications, wound dehiscence, and flap necrosis. RESULTS: The group without a postoperative drain (n = 166) had a significantly lower CSS incidence (8.4%) than the group with a postoperative drain (n = 85, 21.2%) (p < 0.05). In the multivariate analysis, no significant predictors were found for seroma formation. Wound complications significantly decreased, from 31.8% in the group with a drain group to 17.5% in the group without a drain (p < 0.05). CONCLUSION: This study showed that the postoperative drain can be omitted when quilting sutures are applied in ME, ALND, or both. This facilitates day care mastectomy, eliminating drain-related care, discomfort, and related expenses.

Evolution of the surgical technique of minimally invasive Ivor-Lewis esophagectomy: description according to the IDEAL framework.

Totally minimally invasive Ivor-Lewis esophagectomy (Ivor Lewis TMIE) is a technically challenging procedure and is associated with a learning curve. Refinement of surgical technique is an important part of this learning curve. However, detailed descriptions of these refinements according to the idea, development, exploration, assessment, and long-term follow-up (IDEAL) framework are lacking and this study was undertaken to fill this knowledge gap. From 2010 until 2016, all consecutive patients (n = 164) were included from the first patient undergoing Ivor Lewis TMIE. Surgical reports were analyzed and surgeons were interviewed to determine surgical refinements. These data were used to describe the transition of the surgical technique from IDEAL stage IIB to stage III. The main findings were that four refinements were made to the surgical procedure in IDEAL stage IIB: (1) At case 9, the use of the 25 mm OrVil was abandoned, exchanged for a 28 mm EEA stapler and a large omental wrap around the anastomosis was introduced; (2) at case 27, the omental wrap was reduced in volume; (3) at case 60, the omental wrap was refined to cover the full 360° of the anastomosis and (4) at case 77, the fixation of the anvil with the Endostitch was replaced by fixation with two Endoloops®. During the transition from IDEAL stage IIB to stage III, the incidence of anastomotic leakage decreased from 26.0% to 4.6% (P < 0.001) and the incidence of textbook outcome increased from 31.2% to 47.1% (P = 0.039). In conclusion, this study describes the surgical refinements that were made during the progression of Ivor Lewis TMIE from IDEAL stage IIB to IDEAL stage III. During IDEAL stage IIB, postoperative outcome improved as surgical proficiency was gained and the technique was refined.

Short term safety of oncoplastic breast conserving surgery for larger tumors.

BACKGROUND: Oncoplastic surgery (OPS) replaces lumpectomy as standard technique in breast conserving surgery (BCS). OPS has shown to give good cosmetic results, but is it as safe as standard lumpectomy? We conducted a retrospective cohort study to determine postoperative complications, resection margins and re-excision rates for OPS compared to standard lumpectomy. METHODS: Based on data from the 'Netherlands Cancer Registry' and medical records we scored patient, treatment and follow-up related variables. All consecutive patients, with an initially breast conserving operation for primary breast cancer, performed between January 2010 and December 2014 in a dedicated breast center were eligible. Breast surgeons performed the operations. Invasive and in situ tumors were included. Postoperative complications within 30 days after surgery and the need for additional treatment were classified using the Clavien Dindo classification. Involved margin rates and subsequent re-excision were compared. RESULTS: We included 828 women with 842 breast cancers, who had a standard lumpectomy (62.7%) or oncoplastic resection (37.3%). OPS was performed more often for larger tumors (17.5 mm vs 13.6 mm, p = 0.002) and for tumors in the caudal half of the breast (33.1% vs 16.9%, p < 0.001). There was no significant difference in postoperative complications. Positive surgical margins were similar (OPS 22.6%, lumpectomy 18.2%, p = 0.119), as were re-excision rates (p = 0.337). CONCLUSION: Oncoplastic breast surgery can be safely applied in larger tumors, resulting in comparable postoperative complications, resection margins and re-excision rates compared to standard lumpectomy.

[Acute abdominal pain in children caused by pneumonia]. / Acute buikpijn door longontsteking bij kinderen.

Three children presented with symptoms of an acute abdomen. In all three a diagnosis of pneumonia was subsequently established, and the patients made a full recovery following antibiotic therapy. When a paediatric patient presents with symptoms of an acute abdomen, the possibility of pneumonia should be considered. It can be difficult to differentiate between appendicitis and pneumonia because of the subtle clinical signs. Early recognition is, however, important in order to start the correct therapy and to avoid an unnecessary laparotomy.

Long-term follow-up of axillary recurrences after negative sentinel lymph node biopsy: effect on prognosis and survival.

As axillary recurrence (AR) after a negative sentinel lymph node biopsy (SLNB) is rare, the prognosis of these patients is unknown. Since treatment paradigms for patients with breast cancer are shifting toward less axillary surgery, the number of ARs might increase. In this study, we evaluated primary and salvage treatment as well as long-term survival of patients diagnosed with an AR. A retrospective analysis of the cancer registry of 16 breast cancer units in the Netherlands was used to identify patients who developed an AR after a negative SLNB performed between 2002 and 2004. Using local hospital records we recorded primary patient-, tumor-, and treatment-characteristics, as well as salvage treatment. We identified 54 patients with an AR, median 30 months (range 3-79) after SLNB. Eighteen patients (33 %) were initially treated with breast conserving therapy, 15 of whom received external beam radiation therapy (EBRT). Thirty-three patients (61 %) did not receive adjuvant systemic treatment. In 45 of the 54 (83 %) patients, a salvage axillary lymph node dissection was performed showing a median of three positive nodes (range 1-24). Nine patients (17 %) were not treated surgically: three were treated with salvage EBRT and six with salvage systemic therapy only. At time of detection of the AR, a total of 7 patients (13 %) had proven distant metastases. After a median follow-up of 47 months (range 3-118), the 5-year "post-recurrence" distant metastasis free survival was 50 % and overall survival was 58 %. Significant negative predictors of survival were negative estrogen receptor (ER) status and receiving adjuvant chemotherapy at initial treatment. AR following a negative SLNB is associated with a 58 % 5-year OS. Prognostic factors are ER- primary tumor and receiving adjuvant chemotherapy as a part of initial treatment, reflecting an aggressive phenotype. Adequate regional and systemic salvage therapy constitute a chance for long-term survival after AR.

"Axillary recurrences after sentinel lymph node biopsy: a multicentre analysis and follow-up of sentinel lymph node negative breast cancer patients".

INTRODUCTION: The objective of this study was to conduct a multicentre data analysis to identify prognostic factors for developing an axillary recurrence (AR) after negative sentinel lymph node biopsy (SLNB) in a large cohort of breast cancer patients with long follow-up. PATIENTS AND METHODS: The prospective databases from different hospitals of clinically node negative breast cancer patients operated on between, 2000 and 2002 were analyzed. SLNB was performed and pathological analysis done by local pathologists according to national guidelines. Adjuvant treatment was given according to contemporary guidelines. Multivariate analysis was performed using all available variables, a p-value of <0,05 was considered to be significant. RESULTS: A total of 929 patients who did not undergo axillary lymph node dissection were identified. After a median follow up of 77 (range 1-106) months, fifteen patients developed an isolated AR (AR rate 1,6%). Multivariate analysis showed that young age (p = 0.007) and the absence of radiotherapy (p = 0.010) significantly increased the risk of developing an AR. Distant metastasis free survival (DMFS) was significantly worse for patients with an AR compared to all other breast cancer patients (p < 0,0001). CONCLUSION: Even after long-term follow up, the risk of developing an AR after a negative SLN in breast cancer is low. Young age and absence of radiation therapy are highly significant factors for developing an axillary recurrence. DMFS is worse for AR patients compared to patients initially diagnosed with N0 or N1 disease.

[Intracystic carcinoma of the breast: diagnosis and treatment in retrospective investigation and published literature]. / Intracystisch mammacarcinoom: diagnostiek en behandeling in retrospectief onderzoek en literatuurgegevens.

OBJECTIVE: To describe policy and prognosis of patients with a cystic mammary lesion caused by an intracystic mammary carcinoma (ICMC). DESIGN: Retrospective, descriptive. METHOD: The study concerned retrospective analysis of 17 patients presenting with intracystic carcinoma of the breast in an educational clinic in the period 1988-2000, who were selected by searching the national pathology database (PALGA). None of the patients was on hormone replacement therapy. In addition a literature search was carried out in the Medline system. RESULTS: The patients with an intracystic carcinoma of the breast were 10 years older compared to the other breast cancer patients and presented themselves with a palpable mass. Mammography showed a single, well-defined and lobulated mass. Microcalcifications were uncommon. Ultrasound investigation showed a well-defined, inhomogenous and hypoechoic mass. 6 patients had encysted lesions and in 3 a solid, hypoechoic component within the cystic mass was found. Cytology of the cystic fluid is false negative in 36% (5/14). All patients were treated surgically, varying from excisional biopsy to modified radical mastectomy. In 15 patients an intracystic papillary carcinoma (ICPC) was found. 5 patients show a 'pure' ICPC. In the other 10 patients, 5 had an ICPC with a component of DCIS and 5 patients an ICPC with an invasive component. The median follow-up was 84 months (range: 28-165). In 15 patients no evidence of disease was found at follow-up; 2 patients developed local recurrence. The survival was 100%. CONCLUSION: Based on the investigation and on the available literature it is concluded that cysts in breasts of postmenopausal women, who do not use hormone replacement therapy, are malignant until proved otherwise. Ultrasound is invaluable in the diagnostic pathway of intracystic carcinoma of the breast. When ICPC is suspected excisional biopsy with sentinel node biopsy is the treatment of choice. The prognosis is good.
