Laparoscopic Repair of Diastasis Recti: A Case Report and Literature Review

Diastasis recti is a state with separated aponeurosis between two recti caused by weakening of the intercrossing fibers in the linea alba and it causes abdominal protrusion. Common causes comprised of increased intraabdominal pressure, or congenital weakening of myoaponeurotic layer. We describe a patient who underwent laparoscopic repair of diastasis recti. A 30-year-old woman was referred to our outpatient department for an abdominal mass that had appeared 1 year earlier. Physical examination revealed an abdominal wall defect along the midline and computed tomography showed thinning and stretching of the linea alba. The patient underwent laparoscopic repair for diastasis recti. The stretched linea alba was approximated using interrupted sutures from the epigastrium to the suprapubic area. A dual mesh was applied below the peritoneum to prevent recurrence. The patient was discharged without complications, and was followed up for 1 year without recurrence. Laparoscopic repair could be a considerable is a treatment modality for diastasis recti.

Laparoscopic Cholecystectomy in Two Patients with Situs Inversus Totalis: A Case Report

Situs inversus totalis (SIT) is a rare condition in which the viscera are transposed in a mirror image reversal. We report two cases of laparoscopic cholecystectomy (LC) performed for SIT patients. A 63-year old male patient with SIT was diagnosed with symptomatic gallstones. We performed LC by 3-port method. The patient was discharged uneventfully on postoperative day 2. A 57-year old female patient with SIT underwent LC for acute cholecystitis. Due to severe inflammation an assistant was needed. The patient was discharged uneventfully on postoperative day 3. Over 80 cases of LCs in SIT patients have been reported so far and LC has become the standard treatment. The current report confirms the safety of laparoscopy in such cases. Laparoscopic cholecystectomy can be performed safely in SIT patients if care is taken. Surgeons need to be careful of reversed anatomy and unaccustomed working hand.

Single Incision Laparoscopic Cholecystectomy without a Camera Operator

PURPOSE: This study aimed to evaluate the implementation of solo surgery using a laparoscopic scope holder for single incision laparoscopic cholecystectomy (SILC). METHODS: With a glove port and a flexible high-definition scope, SILC was performed through a single trans-umbilical incisional site with CO2 pneumoperitoneum at a pressure of 12 mmHg. Fifty-eight patients who underwent solo SILC using a scope holder (Solo-SILC) were compared to 15 patients who underwent camera operator-assisted SILC (Ca-SILC) in terms of intraoperative and postoperative outcomes. RESULTS: The mean BMI and operation time were 23.0±3.6 kg/m² and 64.4±16.6 min in Ca-SILC and 25.0±3.8 kg/m² and 58.2±27.1 min in Solo-SILC, respectively (p=0.067 and p=0.410). Estimated blood loss was negligible and an additional assistant port was not required in either groups. A case of gallbladder perforation and bile leak was noted in the Ca-SILC group, and 13 cases of bile leak in the Solo-SILC group, with no significant differences (p=0.167) during the surgery. Postoperative outcomes including surgical complications, diet restriction, diarrhea and hospital stay were not significantly different except for shoulder pain (p<0.001). CONCLUSION: Even with the limitations of a small number of patients, Solo-SILC proved to be a feasible technique. To confirm the safety of solo-SILC, further studies with a larger sample size are required.

Laparoscopic Approach for Pancreatic Leiomyosarcoma with Metachronous Liver Metastasis

Although pancreatic leiomyosarcoma (PLM) is a rare malignant pancreatic cancer, it usually shows aggressive biological features such as invasion to an adjacent organ or distant metastasis at the time of diagnosis. Radical resection is the best treatment modality but effective chemotherapies have not been identified. A 58-year-old female was referred to us complaining of intermittent left upper quadrant abdominal discomfort. Imaging studies revealed a 10-cm mass in the pancreatic tail. The patient underwent laparoscopic distal pancreatectomy with splenectomy, and the pathological findings were consistent with PLM. Imaging studies 14 months after surgery revealed multiple liver metastases. Because the patient was young with a sufficient remnant liver, we performed laparoscopic metastatectomy without any postoperative complications. Patients with PLM need frequent check-ups, even after curative resection. The role of laparoscopic resection should be confirmed in the future.

Laparoscopic resection of hilar cholangiocarcinoma

Laparoscopic resection of hilar cholangiocarcinoma is technically challenging because it involves complicated laparoscopic procedures that include laparoscopic hepatoduodenal lymphadenectomy, hemihepatectomy with caudate lobectomy, and hepaticojejunostomy. There are currently very few reports describing this type of surgery. Between August 2014 and December 2014, 5 patients underwent total laparoscopic or laparoscopic-assisted surgery for hilar cholangiocarcinoma. Two patients with type I or II hilar cholangiocarcinoma underwent radical hilar resection. Three patients with type IIIa or IIIb cholangiocarcinoma underwent extended hemihepatectomy together with caudate lobectomy. The median (range) age, operation time, blood loss, and length of hospital stay were 63 years (43-76 years), 610 minutes (410-665 minutes), 650 mL (450-1,300 mL), and 12 days (9-21 days), respectively. Four patients had a negative margin, but 1 patient was diagnosed with high-grade dysplasia on the proximal resection margin. The median tumor size was 3.0 cm. One patient experienced postoperative biliary leakage, which resolved spontaneously. Laparoscopic resection is a feasible surgical approach in selected patients with hilar cholangiocarcinoma.

Adenosquamous Carcinoma Arising in Congenital Choledochal Cyst

Adenosquamous carcinoma arising in congenital choledochal cyst is very rare and herein we report a case thereof. A 37-year-old woman was referred for further evaluation of pancreas head mass and a hepatic nodule on CT. She had been diagnosed with congenital choledochal cyst at 22-years-old and received Roux-en-Y choledochojejunostomy at that time. Endoscopic ultrasonography-guided biopsy proved the pancreas head mass as a squamous cell carcinoma and liver biopsy also proved the liver mass as a metastatic squamous cell carcinoma. We performed pancreaticoduodenectomy and tumorectomy of metastatic liver nodule. Grossly, the primary lesion was located at intrapancreatic portion of choledochal cyst. Histologically, the primary lesion and hepatic nodule was metastatic adenosquamous carcinoma. So far, there have been only three cases of adenosquamous carcinoma arising in congenital choledochal cyst reported in English-language literature. This is another case and the first case reported in Korea.

Clinical Experience of Mesenteric Vascular Diseases and Management

PURPOSE: Mesenteric vascular disease is a rare group of diseases including dissection, embolism, atherosclerosis, and venous thrombosis. Technical advances have led to increased diagnostic rates and new treatments with improved outcomes. The purpose of this study was to analyze the characteristics, methods of diagnosis, treatments, and outcomes of patients with mesenteric vascular diseases at our institution. METHODS: Between November 2003 and April 2010, 30 patients with mesenteric vascular disease diagnosed and treated at Seoul National University Bundang Hospital were reviewed retrospectively. Demographic data, etiology, treatment modality, and outcomes, including complications and mortalities, were analyzed. RESULTS: The mean age of the patients was 63.2 years (range, 43~91 years) and there was a male predominance (21 males vs. 9 females). The etiologies were superior mesenteric artery (SMA) dissection (n=13), SMA embolism (n=8), SMA atherosclerosis (n=5), and superior mesenteric vein thrombosis (n=4). Eleven patients underwent surgical treatment, while 11 patients underwent endovascular intervention and ten patients underwent conservative therapy with or without medication. No recurrence of symptoms or thrombosis was observed, except for one case of surgical thrombectomy, which underwent an endovascular aspiration thrombectomy with thrombolysis 9 days after the surgery. Two cases of technical endovascular treatment failure occurred, and one case of mortality after an endovascular stent insertion was observed. CONCLUSION: The incidence of mesenteric vascular diseases is increasing, and clinical manifestations and prognosis may vary from minor to life-threatening conditions. Early diagnosis is very important and the appropriate choice between endovascular intervention and a surgical approach may lead to good treatment results.
