ABSTRACT
Background Because of the anatomical properties of the inferior calyx, lower pole stones are difficult to remove through the ureter, even if the stones are fragmented. Retrograde intra-renal surgery (RIRS) is typically employed to treat the smaller lower pole stones (1.0-2.0 cm) while percutaneous nephrolithotomy (PCNL) is primarily used to treat the larger diameter stones or when RIRS has failed to clear the stones. This study was conducted to compare mini-PCNL and RIRS for the management of lower pole kidney stones in terms of stone clearance. Material and methods This randomized control trial was conducted in the Department of Urology, Shaikh Zayed Hospital, Lahore from October 2020 to December 2022. A total of 150 patients between the ages of 18 and 80 years with a kidney stone size of 10-20 mm at the lower pole were included. Patients with positive urine culture, anatomical abnormalities, uncontrolled diabetes (hemoglobin{Hb}A1c >9%), and undergone previous renal surgery were excluded. Group A patients were treated with mini-PCNL, while group B patients were managed with RIRS. Follow-up visits were planned four weeks postoperatively with CT KUB (computed tomography of kidneys, ureters, and bladder) plain to assess stone clearance. Results The mean age in group A was 43.27 ± 13.86 years, while in group B was 45.32 ± 14.14 years. Out of 150 patients, 102 (68.0%) were males and 48 (32.0%) were females. Mean size of the stone was 15.30 ± 2.21 mm. Stone clearance after mini-PCNL was found in 69 (92.0%) patients and after RIRS in 59 (78.67%) patients (p-value = 0.021). Mean hospital stay after RIRS was 1.1 ± 0.09 days, while it was 2.3 ± 0.64 days after mini-PCNL (p-value < 0.001). Two (2.67%) patients in the mini-PCNL group developed bleeding postoperatively. The stone clearance rate in older patients (51 to 80 years) was significantly higher in the mini-PCNL group than RIRS group. Similarly, the stone clearance rate in female patients and in patients with larger stones (16 to 20 mm) was found to be higher in mini-PCNL group as compared to the RIRS group. Conclusion This study concluded that both mini-PCNL and RIRS are safe and efficient techniques for treating lower pole kidney stones with a size of 11-15 mm. However, mini-PCNL has a higher stone clearance rate compared to RIRS in the treatment of stones larger than 15 mm in size. This study further suggested that patients treated with mini-PCNL had a longer hospital stay compared to patients treated with RIRS.
ABSTRACT
Background Anal fistula, or fistula-in-ano, is a chronic abnormal communication between the epithelialized surface of the anal canal and the perianal skin. Video-assisted anal fistula treatment (VAAFT) is a novel, minimally invasive, and sphincter-saving alternative to traditional seton use. This study aimed to determine the short-term and long-term outcomes of VAAFT compared with seton treatment. Material and methods This randomized control trial was conducted at the Department of Surgery, Services Hospital, Lahore, from August 2014 to July 2020. Patients were randomly assigned to either the VAAFT group or the seton group, and postoperative outcomes were assessed for up to three years. Results The study included 80 patients (64 men and 16 women) with a mean age of 39.1 ± 11.2 years. The most common type of fistula was a transsphincteric fistula (n=36, 45%). The mean duration of surgery was significantly longer in the VAAFT group (78.6 minutes) compared with the seton group (36.97 minutes; p=0.000). The mean pain score was significantly higher in the VAAFT group (4.22) compared to the seton group (2.82, p=0.000). The mean time to return to work was shorter in the VAAFT group (7.4 days) than in the seton group (9.2 days, p=0.000). The mean healing time was significantly shorter for patients treated with VAAFT (5.75 weeks) than for those treated with a seton (9.7 weeks; p=0.000). Fistula recurrence after one, two, or three years was not significantly different between groups, and neither group had incidences of anal incontinence. Conclusions VAAFT is associated with earlier healing time and earlier return to work than the traditional seton technique, with no significant difference in fistula recurrence. VAAFT is minimally invasive and, when used in patients where indicated, allows for a prompter return to routine life for the patients, which is an optimal outcome for both patients and physicians.
ABSTRACT
Background Nonspecific abdominal pain (NSAP) is a pain for which no immediate cause is evident on acute admission and does not necessitate emergency surgical intervention. NSAP is a frequent reason for presentation in the emergency department (ED). Laparoscopy is a well-established technique that allows a surgeon to visualize the abdominal cavity after insufflation through a few small incision ports. Despite the increasing availability of laparoscopic investigation, the availability of a laparoscope in the ED settings in Pakistan is low due to the expense and maintenance needs of the system. Objective This study aimed to evaluate the role of laparoscopy in diagnosing the cause of acute NSAP and its role in treating the pathology of disease in patients presenting to the emergency department (ED) of Services Hospital, which is a government sector hospital in Lahore, Pakistan. Materials and methods This study was conducted in Services Hospital Lahore, Pakistan, from January 1, 2016 to December 31, 2019. The study included patients aged 12 to 70 years of either sex who presented to the ED with abdominal pain for whom no diagnosis could be achieved on clinical assessment, laboratory findings, and radiological findings (x-ray abdomen, ultrasonography, and computed tomography scan). All study participants underwent diagnostic laparoscopy under general anesthesia. Patients were monitored weekly via follow-up postoperatively for the first month and then monthly for 12 months. All study data were recorded on a predesigned proforma. The data were analyzed using IBM Corp. Released 2012. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp. Results A total of 122 patients diagnosed with acute NSAP were enrolled in our study (mean age, 46.4 ± 20.3 years). The study population consisted of 52 male patients (42.6%) and 70 female patients (57.4%). Our study participants had a mean body mass index of 24.2 ± 3.3 kg/m2. The most common ED presentation was lower abdominal pain. One hundred sixteen patients (95.1%) had positive findings on laparoscopy, while six patients (4.9%) had no identified pathology on laparoscopy. The most frequent pathology was appendicular in origin, followed by pelvic inflammatory disease. Surgical management of patients through laparoscopy was performed in 97 patients (79.5%). Conversion to laparotomy was done in 12 patients (9.8%). Definite diagnosis was established in 118 patients (96.7%). Port site infection occurred in four patients (3.3%), chest infection in five patients (4.1%), deep venous thrombosis in one patient (0.8%), and anastomotic leakage in one (0.8%) patient. Four patients (3.3%) developed recurrence of symptoms. Conclusions This study explored the role of laparoscopy in diagnosing and treating patients presenting to the ED with acute NSAP. According to our results, laparoscopy is a safe and effective method for diagnosing and treating acute NSAP with low postoperative morbidity and potentially decreased risk of postoperative complications. Physicians should consider laparoscopy as a first-line invasive investigation for patients presenting with undiagnosed acute abdominal pain.
