UNASSIGNED: We describe a case of an adrenal cavernous hemangioma that was surgically resected because of tumor growth and intratumoral hemorrhage.
UNASSIGNED: A 73-year-old woman presented with an enlarged adrenal tumor and intratumoral hemorrhage during the follow-up of an incidental adrenal tumor. A computed tomography showed that the left adrenal tumor had grown from 23 to 44 mm over 1 year. Blood tests revealed a normal metabolic profile. Paragangliomas and metastatic tumors were suspected on imaging. Laparoscopic adrenalectomy was performed to prevent tumor rupture due to further bleeding. No adhesions or bleeding were observed around the tumor during surgery. Pathological diagnosis was adrenal cavernous hemangioma.
UNASSIGNED: Adrenal cavernous hemangioma is difficult to distinguish preoperatively from other adrenal tumors, including malignant tumors. The intraoperative findings of this case suggest that laparoscopic adrenalectomy is a safe treatment option for relatively small adrenal cavernous hemangioma.

BACKGROUND: Schwannomas in the renal hilum are rare among retroperitoneal tumors. However, the possibility of malignant findings cannot be ruled out, and surgery is often indicated. This case was expected to be difficult to remove laparoscopically because the tumor was sandwiched between the arteriovenous veins of the renal portal. Sometimes, the tumor should be resected with a conservative approach to the kidney to preserve the renal function.
METHODS: Our patient was a 51-year-old Asian-Japanese man who was referred to our department for a retroperitoneal tumor in the renal hilum. Since malignancy could not be ruled out due to its size (45 × 48 × 55 mm) on imaging, the tumor was excised laparoscopically. Histopathology revealed schwannoma.
CONCLUSIONS: We herein report a case in which a renal hilar tumor between renal arteriovenous vessels was successfully resected laparoscopically.

UNASSIGNED: Laparoscopic cholecystectomy is one of the common surgeries occurring worldwide and the gold standard for the management of gallstone disease. The non-absorbable surgical clips may slip and can migrate causing a variety of problems as such, choledocholithiasis.
UNASSIGNED: The authors report a case of 43-year-old female who presented with the complaint epigastric pain. She had undergone cholecystectomy 7 years back for symptomatic cholelithiasis. Ultrasonography of the abdomen showed a dilated common bile duct following which endoscopic retrograde cholangiopancreatography was done. A single black-colored stone with the metal clip was retrieved.
UNASSIGNED: Post-cholecystectomy clip migration should be considered as one of the differentials for choledocholithiasis. Ultrasonography of the abdomen shows the dilated common bile duct. Further management is done by endoscopic retrograde cholangiopancreatography.
UNASSIGNED: Surgical clips acting as nidus for choledocholithiasis is rare these days but should be considered as one of the differentials for pain abdomen.

Low-grade appendiceal mucinous neoplasm (LAMN) is principally characterized by low-grade cytology without evidence of invasion to other organs. We report a LAMN surgical case whose appendiceal tumor penetrated the sigmoid colon wall. An 87-year-old man was referred for endoscopic resection (ER) of a colon polyp. Despite four ERs over 5 years, the polyp recurred at the same site. Laparoscopic surgery revealed a dilated appendix firmly attached to the sigmoid colon. We performed en bloc resection of both the sigmoid colon and appendix without tumor exposure. The histopathological evaluation showed that the LAMN had penetrated the sigmoid colon wall, forming two polyps on the colonic mucosa. In cases where the appendiceal-colonic fistula is suspected, en bloc resection of the appendix and colon wall should be considered.

OBJECTIVE: This study investigated the impact of sidedness of colorectal cancer (CRC) in elderly patients on the prognosis.
METHODS: In a sub-analysis of a multicenter case-control study of CRC patients who underwent surgery at ≥ 80 years old conducted in Japan between 2003 and 2007, both short- and long-term outcomes were compared between right-sided colon cancers (RCCs) and left-sided colorectal cancers (LCCs). RCCs were defined as those located from the cecum to the transverse colon.
RESULTS: Among the 1680 patients who underwent curative surgery, 812 and 868 had RCCs and LCCs, respectively. RCCs were more frequent than LCCs in those who were female, had renal comorbidities, and had a history of abdominal surgery. Regarding tumor characteristics, RCCs were larger, invaded more deeply, and were diagnosed as either mucinous or signet ring-cell carcinoma more frequently than LCCs. Regarding the prognosis, patients with RCCs had a significantly longer cancer-specific survival (CS-S) and cancer-specific relapse-free survival (CS-RFS) than those with LCCs. Furthermore, sidedness was determined to be an independent prognostic factor for CS-S and CS-RFS.
CONCLUSIONS: RCCs, which accounted for half of the cases in patients ≥ 80 years old, showed better long-term outcomes than LCCs.

BACKGROUND: Ventriculoperitoneal (VP) shunt insertion is a means of diverting cerebrospinal fluid (CSF) for management of hydrocephalus. Revision rates, operating time, and length of stay (LOS) following laparoscopic insertion of the distal catheter have been mixed. There are limited data on the role of adhesiolysis during VP shunt insertion. Valve characteristics have also been shown to influence patient outcomes. There is a paucity of Australian data reporting on the effect of these variables on shunt outcomes. We aimed to study patient demographics, indications, and surgical and instrument variables in the Australian context.
METHODS: We performed a retrospective, multi-surgeon, single-centre analysis of VP shunts inserted in adults via an open or laparoscopic technique. Data on patient demographics and surgery characteristics were collected from the hospital medical records and the Australasian Shunt Registry. The primary outcome was shunt revision rate and secondary outcomes were postoperative complications, operating time and LOS, and shunt survivability.
RESULTS: Fifty-six participants were eligible for analysis. The overall revision rate was 14.3 %, which was lower than the national average. The distal catheter revision rate was 0 %. Laparoscopic insertion of the distal catheter was shown to significantly reduce operating time (70.4 min in the open group and 50.7 min in the laparoscopic group, p < 0.001). This was demonstrated across different aetiologies, and when controlling for age and valve-type (p < 0.05). The revision rate of non-programmable was higher than programmable valves (42.9 % versus 2.9 %, respectively). There were no differences between previous abdominal surgery, LOS, complication, or revision rate between open and laparoscopic insertion. VP shunt survivability was greater in the laparoscopic group (90-day shunt survival of 96.7 % and 92 % in the laparoscopy and open groups, respectively; p > 0.05). We did not find any significant difference in operating time or length of stay for age, sex, or previous abdominal surgery, even when accounting for surgical technique. Indication and shunt survivability varied widely between age groups. The use of laparoscopic insertion increased over time, though surgeons did not crossover techniques.
CONCLUSIONS: The overall distal revision rate of VP shunts is low. Laparoscopic insertion of the distal catheter reduces operating time and may improve shunt survivability. Larger studies are needed to confirm differences in shunt survivability in open versus laparoscopic distal catheter insertion, between age groups, clinical indications, and valve type on patient outcomes.

Urachal anomalies are rare congenital lesions of the genitourinary tract and are important causes of pediatric and adolescent hospital presentations. It can mimic many other causes of intraabdominal pathology and fever, and pose diagnostic challenges, often aided by imaging, is crucial to prevent complications such as infection and calculus formation. Surgical intervention, preferably laparoscopic, is the primary treatment, with complete excision necessary to avoid potential malignant transformation.

This case report discusses the management of a 46-year-old male patient with autosomal dominant polycystic kidney disease and a high body mass index, who underwent a semi-simultaneous procedure involving hand-assisted laparoscopic bilateral nephrectomy to alleviate severe abdominal symptoms and prepare for a kidney transplantation, all using the same incision. This is the first reported occurrence of such a procedure in Saudi Arabia. Post-operatively, the patient made a successful recovery with excellent kidney function and no complications.

Cryptorchidism is defined as the extra-scrotal position of the testes. It is a common disorder in male children, but rarely in adult patients. The association of cryptorchidism with hernia is a common finding in childhood, but is not frequent in adults or the elderly. Herein, we report a series of three cases (28-, 24-, and 34-year-old men) of adult inguinal hernia combined with cryptorchidism successfully managed by laparoscopic surgery under the same operative view. Laparoscopic transabdominal preperitoneal repair and orchiectomy were performed in all patients. No complications occurred in the postoperative period, and the patients were discharged on the first or second postoperative day. Pathological examination of the specimens revealed atrophic testes without malignancy. No hernia recurrence was observed during follow-up. The laparoscopic approach in the combined pathology of inguinal hernia and cryptorchidism is feasible in adult patients and has multiple advantages in terms of diagnosis and management.

UNASSIGNED: Amyand\'s hernia is a rare type of inguinal hernia which contains vermiform appendix in the inguinal sac, seldom complicated by acute appendicitis. It is usually repaired by open inguinal approach, but laparoscopic technique has been increasingly described in literature; nevertheless, standard of care is far from being defined. Here we report the case of Amyand\'s hernia complicated by acute appendicitis and simultaneous symptomatic left inguinal hernia, both repaired by laparoscopic technique.
METHODS: A 85-years-old man presented with acute appendicitis in Amyand\'s hernia and simultaneous incarcerated left inguinal hernia.
UNASSIGNED: After complete preoperative work-up, the patient underwent laparoscopic appendectomy and laparoscopic bilateral hernia repair with mesh.
CONCLUSIONS: Laparoscopic approach may be safe and feasible for Amyand\'s hernia treatment in emergency setting when performed by expert hands, with minimized risk of surgical site infection (SSI), quick recovery and reduced hospital stay. Laparoscopic hernia repair with mesh can be a reasonable approach in selected cases of bilateral or recurrent hernia, and concomitant intrabdominal inflammation, especially when contamination is scarse and limited to a restricted area.
