Surgery of abdominal wall endometriosis associated with clear-cell carcinoma: Case report and review.

Abdominal wall is a rare location for endometriosis, with a reported incidence of parietal endometriosis of approximately 0.03 to 0.4%. It most often occurs in the aftermath of a caesarean section and is associated with pelvic endometriosis in only 5 to 15% of cases. Rare cases of malignant transformation have been described, mainly in the form of clear-cell tumours. We report the case of a 52-year-old patient with a history of endometriosis who presented with a retractile parietal mass at the level of her caesarean scar. Histological analysis confirmed a clear-cell adenocarcinoma (CCC). Few cases of endometriosis - associated CCC are described in the literature. A review of the literature suggests radical surgical treatment combined with adjuvant radio-chemotherapy. However, the prognosis is poor. The aim of this case report is to suggest the diagnosis of malignant transformation in the presence of a rapidly evolving parietal mass in the context of endometriosis and a history of caesarean section.

Resection of an Esophageal Diverticulum by Thoracoscopy in Prone Position.

Diverticula of the middle one third of the esophagus are rare clinical entities, by comparison with the more common epiphrenic diverticula. For midesophageal diverticula, a minimally invasive approach has not been standardized. This report presents the case of a 60-year-old man with a large midesophageal diverticulum who was treated successfully by four-port video-assisted thoracic surgery while he was in the prone position. Thoracoscopy is a good approach for direct visualization of the diverticulum, and the prone position has several advantages to help clear the view. Routine myotomy for middle one-third diverticula is not advised, given the risk of poor functional results and diverticulization of the myotomy itself.

Ventral hernia surgery in morbidly obese patients, immediate or after bariatric surgery preparation: Results of a case-matched study.

BACKGROUND: Obesity is a risk factor for the development of ventral hernia and increases the risk of recurrence and surgical site infection after hernia repair (HR). OBJECTIVES: We tested the hypothesis that bariatric surgery (BS) before HR would decrease these risks in patients with morbid obesity. SETTING: University hospital, France. METHODS: We retrospectively compared 2 groups of patients with morbid obesity in a case-matched study; 1 underwent immediate HR surgery (control), and the other initially underwent BS and then HR after weight loss (case). Patients were individually matched at a 2:1 ratio according to defect size (<7 or ≥7 cm), obesity grade (<40 or ≥40 kg/m²), American Society of Anesthesiologists score, sex, smoker status, and presence of chronic obstructive pulmonary disease. RESULTS: From 2000 to 2017, 41 patients underwent BS, in association with herniorrhaphy in 14 cases (34%). Initial body mass index was higher in the BS group (46.7 ± 6.4 versus 42.4 ± 7.2, P < .0001) but had decreased by the time of HR (34.1 ± 6.5 versus 42.3 ± 7.2, P < .0001). Prosthetic HR was performed after 21.5 months (range, 7-87); however, 7 patients did not receive HR at this time due to insufficient weight loss. Postoperative morbidity was similar in the 2 groups. Hospital stay was shorter in the BS group (6.2 ± 2.6 versus 10.7 ± 9.3 d, P = .002). After a median follow-up of 4.6 ± 4.1 years, the recurrence rate was lower in the BS group (2/30, 6.7%) than in the control group (12/50, 24%; P = .048). CONCLUSION: For morbidly obese patients with ventral hernia, BS before HR surgery can decrease recurrence without increasing morbidity.

Can We Predict the Lateral Compartment Lymph Node Involvement in RET-Negative Patients with Medullary Thyroid Carcinoma?

BACKGROUND: Lateral lymph node dissection (LND) in the absence of macroscopic nodal metastasis remains controversial in sporadic medullary thyroid carcinoma (MTC). OBJECTIVES: The aims of our study were to determine the risk of lateral lymph node (LN) metastases with a focus on lateral contralateral N1, and to define a risk-adapted surgical treatment for these patients. METHODS: All patients who underwent surgery from 1980 to 2012 for previously untreated RET-negative MTC were reviewed. We focused on the lateral compartments of LN metastases and identified three groups: no lateral LN metastases, ipsilateral lateral (ILL)-LN metastases with no contralateral LN involvement, and contralateral lateral (CLL)-LN metastases. RESULTS: Overall, 131 patients underwent surgery for RET-negative MTC. A total thyroidectomy with LND was performed in 112 patients (85 %), including 97 patients who had an ILL-LND and 92 patients who had a CLL-LND. Lateral LN metastases (N1) occurred in 40 patients (37 %): 31 patients (32 %) had ILL-LN metastases with no contralateral LN involvement, and 9 patients (10 %) had CLL-LN metastases. The preoperative cut-offs for LN metastases in the ILL compartment were very low, with a smallest tumor size of 5 mm, and lowest serum calcitonin level of 38 pg/ml. Disease-free survival rates decreased from 92 % for patients with no lateral LN metastases to 41 % for patients with ILL-LN metastases and 0 % for patients with CLL-LN metastases. CONCLUSIONS: ILL-LND should be performed in every patient and only a minority of MTC patients with small micro-MTC, and low serum calcitonin levels should not have a CLL-LND.

Antroduodenectomy with Gastroduodenal Anastomosis: Salvage Emergency Surgery for Complicated Peptic Ulcer Disease--Results of a Double Institution Study of 35 Patients.

BACKGROUND: Endoscopic and interventional techniques are currently the mainstay of management of bleeding duodenal ulcer. As well, for patients with perforated duodenal ulcer, laparoscopic simple closure is nowadays usually performed. Although indications for emergency antroduodenectomy have declined, this procedure is still necessary as a salvage option when conservative management has failed or is not practicable. Our study aimed to evaluate indications and results of antroduodenectomy with gastroduodenal anastomosis in current practice and to examine the factors that predict operative outcomes. METHODS: All patients who underwent emergency antroduodenectomy with gastroduodenal anastomosis in two surgical care departments specialized in emergency digestive surgery were studied from 2000 to 2015. RESULTS: Thirty-five patients (27 males, 77 %) with a median age of 68 years (20-90) underwent emergency antroduodenectomy with gastroduodenal anastomosis. Indications were bleeding and perforated duodenal ulcer in 24 and 11 patients, respectively. The overall complication rate was 69 %, especially because of a high rate of medical complications (57 %). Only two patients (6 %) required reoperation for anastomotic leakage. The overall mortality rate was 40 % (n = 14). According to the univariate analysis, age >70, >3 comorbidities, ASA score >2, and postoperative medical complications were associated with an increased risk of in-hospital mortality. In the multivariate analysis, age and ASA score remained independent risk factors. No recurrence of complicated duodenal disease was observed. CONCLUSION: Antroduodenectomy with gastroduodenal anastomosis is a safe and effective long-term strategy, with a low and acceptable rate of surgical complications, for complicated duodenal ulcer not responding to conservative measures.
