Intertrochanteric femoral fracture with lateral wall fracture at the lag screw insertion site may cause postoperative anterior wall fracture and lead to deterioration in activities of daily living.

BACKGROUND: Incomplete reduction and fixation of intertrochanteric femoral fractures significantly affect patients' daily activities. The lateral wall's integrity is pivotal in such fractures. This study examines instability, particularly lateral wall fractures at the lag screw insertion site and postoperative anterior wall fractures. METHODS: Overall, 161 patients with femoral intertrochanteric fractures were included. Three-dimensional computed tomography was conducted preoperatively and 3 weeks postoperatively to determine the postoperative anterior wall fractures incidence. Patient background, operative time, intraoperative blood loss, postoperative telescoping, and daily living activities were compared. RESULTS: The study recorded 51 cases of lateral wall fractures at the lag screw insertion site and 17 of postoperative fractures of the anterior wall. Postoperative fractures of the anterior wall were found in 3 of 110 and 14 of 51 patients in the group without and with the lag screw insertion site, respectively. The group of postoperative fractures of the anterior wall had significantly lower bone mineral density, longer operative time, and increased intraoperative blood loss. At 4 weeks postoperatively, the group of postoperative fractures of the anterior wall showed increased telescoping and decreased motor component of the functional independence measure (with postoperative fractures of the anterior wall: 28, without postoperative fractures of the anterior wall: 30), and significant reductions were observed in the transfer and locomotion items, indicating lower limb function (with postoperative fractures of the anterior wall group: 11, without postoperative fractures of the anterior wall group: 12). CONCLUSIONS: Postoperative anterior wall fractures occurred in 27.5% cases with lateral wall fractures at the lag screw insertion site. Three-dimensional computed tomography is useful for preoperative evaluation of lateral wall fractures at the lag screw insertion site to assess instability. Postoperative fractures of the anterior wall related reduction in daily living activities needs attention.

Focal segmental glomerular sclerosis recurrence with massive proteinuria and anuria immediately after kidney transplantation.

Here, we report a case of focal segmental glomerular sclerosis (FSGS) recurrence immediately (47 minutes) after transplantation. A 1-hour biopsy specimen showed large periodic acid-Schiff-positive granules within the cells of the swollen proximal tubule, while electron microscopy revealed podocyte swelling and partial foot process effacement. These findings were worse on day 2 biopsy. Massive proteinuria and anuria were then observed. Two courses (2 × 2 times) of plasmapheresis and rituximab were administered, and the graft function gradually recovered. A day 22 biopsy specimen showed improvement in findings compared to those observed on day 2. One year after transplantation, no signs of FSGS recurrence are evident, and graft function remains good.

Safe and feasible inflow occlusion in laparoscopic liver resection.

BACKGROUND: A major challenge in laparoscopic liver resection to avoid massive hemorrhage from the transection plane. METHODS: This study investigated 32 consecutive patients who underwent laparoscopic or laparoscopically assisted hepatic resection and had the hepatoduodenal ligament encircled by vessel tape using an Endo Retract Maxi as a tourniquet for complete interruption of blood inflow to the liver. RESULTS: Laparoscopic encircling of the hepatoduodenal ligament was performed in a few minutes without any complications for any of the 32 patients. CONCLUSIONS: Laparoscopic Pringle's maneuver using an Endo Retract Maxi can be performed easily for all patients undergoing laparoscopic liver resection.

Laparoscopic major hepato-biliary-pancreatic surgery: formidable challenge to standardization.

INTRODUCTION: Although laparoscopic colorectal or gastric surgery has become widely accepted as a superior alternative to conventional open surgery, the surgical management of hepato-biliary-pancreatic disease has traditionally involved open surgery. Recently, many reports have described laparoscopic partial liver resection, lateral segmentectomy, and distal pancreatectomy. However, laparoscopic major hepato-biliary-pancreatic surgery, such as hepatic lobectomy and pancreaticoduodenectomy, has not been widely developed because of technical difficulties. METHODS: We describe our experience with laparoscopic major hepato-biliary-pancreatic surgery, including right hepatectomy using hilar Glissonean pedicle transaction, and pylorus-preserving pancreaticoduodenectomy. CONCLUSION: Although our experience is limited, and randomized study is necessary to elucidate the appropriate indications for and effects of the present procedures, we believe that laparoscopic major hepato-biliary-pancreatic surgery can be feasible, safe, and effective in highly selected patients, and that it will be one of the standard therapeutic options for carefully selected patients with hepato-biliary-pancreatic disease.

Hepatic hilar resection for hilar cholangiocarcinoma based on a reclassification.

Major hepatic resection for hilar cholangiocarcinoma is reportedly closely associated with severe postoperative complications. We performed a new limited resection that included total resection of the caudate lobe and anterior segment (ventral region of the right paramedian sector), and bile duct resection with hepaticojejunostomy in 3 patients with hilar cholangiocarcinoma that had not infiltrated the hepatic artery or portal vein. In all 3 patients, curative surgical resections were obtained and no serious complications were encountered. This new limited resection based on a reclassification of the liver may offer an effective procedure in limited patients with hilar cholangiocarcinoma.

PTHrP-producing tumor: squamous cell carcinoma of the liver accompanied by humoral hypercalcemia of malignancy, increased IL-6 and leukocytosis.

A 77-year-old man was admitted to our hospital showing symptoms of general fatigue and appetite loss. He had leukocytosis, thrombocytosis and hypercalcemia with elevated serum levels of parathyroid hormone related peptide (PTHrP) and interleukin-6 (IL-6). An increase in tumor markers SCC and CYFURA21-1 was observed. The liver contained a huge tumor, which was proved to be PTHrP producing squamous cell carcinoma by immuno-histochemical analysis. Since the tumor did not express IL-6, it was assumed to be induced by PTHrP in osteoblasts. This is the first report of PTHrP producing squamous cell carcinoma of the liver.

A Review of Autologous Islet Transplantation.

Autologous islet transplantation after total or semitotal pancreatectomy aims to preserve insulin secretory function and prevent the onset of diabetes. The major indication for pancreatectomy is chronic pancreatitis with severe abdominal pain, a benign pancreatic tumor, and trauma. The metabolic outcome of autologous islet transplantation is better than that of allogeneic transplantation and depends on the number of transplanted islets. Achieving islet isolation from a fibrous or damaged pancreas is one of the biggest challenges of autologous islet transplantation; a major complication is portal vein thrombosis after crude islet infusion. However, the incidence of portal vein thrombosis has decreased as islet preparation techniques have improved over time.

Comparison of laparoscopy-assisted and open pylorus-preserving pancreaticoduodenectomy for periampullary disease.

BACKGROUND: Although many reports have described laparoscopic pancreatic surgery, pancreaticoduodenectomy (PD) has not been widely accepted. The present study aimed to compare laparoscopy-assisted and open pylorus-preserving pancreaticoduodenectomy (PPPD) to investigate the feasibility, safety, and tumor clearance. METHODS: Fifteen patients with periampullary disease underwent laparoscopy-assisted PPPD, in which resection was performed laparoscopically and the reconstruction was performed through a small midline incision. These patients were compared with 15 patients who, during the same period, underwent conventional open PPPD. RESULTS: Mean operative time and mean blood loss were similar between groups. No significant differences in the incidence of complications or hospital stay were noted between groups. Surgical margin and number of lymph nodes found in the resected specimen did not differ between groups. CONCLUSIONS: Laparoscopy-assisted PPPD is on the same level with conventional open surgery in terms of perioperative outcomes or treatment efficacy.

Total laparoscopic resection of the gallbladder together with the gallbladder bed.

Patients with carcinoma of the gallbladder that is preoperatively diagnosed by radiology do not undergo laparoscopic resection, because such surgery is thought to worsen the prognosis of gallbladder carcinoma. However, the prognosis for patients with incidental T2 gallbladder carcinoma who are treated laparoscopically is reportedly no worse than that for patients undergoing conventional surgery. We successfully performed total laparoscopic resection of the gallbladder together with the gallbladder bed without any complications. We believe that this procedure represents a valid therapeutic option for carefully selected patients with T2 carcinoma of the gallbladder.

Renal cell carcinoma with unusual metastasis to the gallbladder.

Gallbladder involvement in patients with renal cell carcinoma (RCC) is extremely rare. We present a report of a 61-year-old man with a synchronous RCC metastasis to the gallbladder presenting as an intraluminal polypoid mass simulating primary gallbladder carcinoma. Enhanced abdominal computed tomography demonstrated a well-enhanced polypoid lesion in the gallbladder. Intraoperative rapid pathological examination of the gallbladder tumor showed clear cell-type cancerous cells. Microscopically, tumor cells of both the resected kidney and gallbladder had round uniform nuclei, clear cytoplasm, and well-defined cytoplasmic borders, forming alveolar patterns. Immunohistochemically, the tumor cells were negative for cytokeratin 7 (CK7) and carcinoembryonic antigen (CEA), which is usually positive in primary clear cell carcinoma of the gallbladder. Therefore, the final diagnosis was RCC with a synchronous gallbladder metastasis.
