Abstract Background This study aims to describe the clinical features of the isolated primitive splenic hydatid cyst, discuss and compare the different surgical approaches of this uncommon disease. Methods This is a descriptive retrospective study carried out over a period of 7 years extending from January 2013 to December 2019 reporting eight cases of isolated primitive splenic hydatid cysts. Data were collected from the register of the general surgery department of the Jendouba regional hospital. Files concerning another associated hydatid localization were excluded. Four patients underwent total splenectomy and four of them underwent different spleen preserving surgical techniques including resection of the protruding dome, partial splenectomy and pericystectomy. Results The diagnosis was incidentally made in 50% of cases. The main other revealing complaints are pain in the left upper quadrant of abdomen in 25% of cases and a painless renitent mass in the same quadrant in only 12,5%. None of patients who underwent total splenectomy had fever or sings of postoperative sepsis. Compared to those who had total splenectomy, patients who underwent spleen preserving surgery had a longer average hospital stay (9 vs 6,25 days) related to post-operative complications including abscess in the residual cavity after protruding dome resection in one patient and post-operative haemorrhage in one patient. Conclusions The current case series argues in favor of total splenectomy, preferably by laparoscopic route whenever the technical platform allows it, associated with some specific peri-operative therapeutic measures. It seems to be the safest way that helps to avoid post-operative complications of spleen saving surgical modalities. These complications are usually difficult to manage in poor countries with limited technical resources. Total splenectomy guarantees at least a decreased hospital stay, reduced healthcare costs, and the absence of recurrence in highly endemic underdeveloped countries.

Objectives: To compare the tissue based Desarda repair with Lichtenstein mesh technique for inguinal hernia in terms of operation time, hospital stay, return to normal activities, cost and post-operative complications such as seroma formation, surgical site infection and recurrence. Study Design: Randomized Controlled trial. Setting: Department of General Surgery Hayatabad Medical Complex, Peshawar, Pakistan. Period: June 2017 to June 2019. Material & Methods: Total of 150 male patients were selected using Non probability consecutive sampling technique. Patients were randomized into two groups using lottery method. 75 patients in group A underwent hernia repair with Desarda no mesh technique and 75 patients in group B underwent hernia repair by performing Lichtenstein mesh technique. Patients were followed up after 2 weeks, 1 month, 3 months, 6 months and 1 year. Data was evaluated using version 22 of SPSS and expressed as a standard deviation, mean. Independent-sample T test was used to compare continuous variables. Categorical variables were compared using Fischer’s exact test. P value of less than 0.05 was considered significant. Results: The mean age of Desarda group was 44.59±10.58 years while it was 44.44±10.30 years in the Lichtenstein group (P=0.932).Mean Operative time was less for Desarda repair (42.08 ± 3.42 min) when compared to Lichtenstein repair (49.01 ± 4.77min) (p=0.000). The average hospital stay after Desarda repair was 2.08±0.27 days and after Lichtenstein repair it was 3.00±0.40 days (p=0.000). After Desarda procedure the average duration to return to work was 11.10±2.32 days while it was 13.92±2.24 days in Lichtenstein procedure (p<0.0001). The total cost of the operation was (Rs 3893±293) in Desarda group and (Rs 7844±175) in the Lichtenstein group (p=0.000). When compared for observed postoperative complications like seroma, wound infection and recurrence in both groups all the p-values were > 0.05 and were non-significant statistically. Conclusion: In comparison to Lichtenstein mesh repair, Desarda technique is cost effective, easy to learn, patients have less hospital stay, less chances of post-operative complications and early return to basic physical activities However Desarda technique is not possible in patients having thin external oblique aponeurosis with divided fibers and here Lichtenstein technique is better option. Further long term randomized control trials are required on large-scale to evaluate this technique further.

 Treatment for coronavirus disease 2019 (COVID19) pneumonia remains empirical and the search for therapies that can improve outcomes continues. Melatonin has been shown to have anti-inflammatory, antioxidant, and immune-modulating effects that may address key pathophysiologic mechanisms in the development and progression of acute respiratory distress syndrome (ARDS), which has been implicated as the likely cause of death in COVID19. We aimed to describe the observable clinical outcomes and tolerability of high-dose melatonin (hdM) given as adjuvant therapy in patients admitted with COVID19 pneumonia. We conducted a retrospective descriptive case series of patients who: 1) were admitted to the Manila Doctors Hospital in Manila, Philippines, between March 5, 2020 and April 4, 2020; 2) presented with history of typical symptoms (fever, cough, sore throat, loss of smell and/or taste, myalgia, fatigue); 3) had admitting impression of atypical pneumonia; 4) had history and chest imaging findings highly suggestive of COVID19 pneumonia, and, 5) were given hdM as adjuvant therapy, in addition to standard and/or empirical therapy. One patient admitted to another hospital, who one of the authors helped co-manage, was included. He was the lone patient given hdM in that hospital during the treatment period. Main outcomes described were: time to clinical improvement, duration of hospital stay from hdM initiation, need for mechanical ventilation (MV) prior to cardiopulmonary resuscitation, and final outcome (death or recovery/discharge). Of 10 patients given hdM at doses of 36-72mg/day per os (p.o.) in 4 divided doses as adjuvant therapy, 7 were confirmed COVID19 positive (+) by reverse transcription polymerase chain reaction (RT-PCR) and 3 tested negative  (-), which was deemed to be false (-) considering the patients’ typical history, symptomatology, chest imaging findings and elevated bio-inflammatory parameters.  In all 10 patients given hdM, clinical stabilization and/or improvement was noted within 4-5 days after initiation of hdM. All hdM patients, including 3 with moderately severe ARDS and 1 with mild ARDS, survived; none required MV. The 7 COVID19(+) patients were discharged at an average of 8.6 days after initiation of hdM. The 3 highly probable COVID19 patients on hdM were discharged at an average of 7.3 days after hdM initiation. Average hospital stay of those not given hdM (non-hdM) COVID19(+) patients who were admitted during the same period and recovered was 13 days. To provide perspective, although the groups are not comparable, 12 of the 34 (35.3%) COVID19(+) non-hdM patients admitted during the same period died, 7/34 (20.6%) required MV; while 6 of 15 (40%) non-hdM (-) by RT-PCR but highly probable COVID19 pneumonia patients also died, 4/15  (26.7%) required MV. No significant side-effects were noted with hdM except for sleepiness, which was deemed favorable by all patients, most of whom had anxiety- and symptom-related sleeping problems previously. HdM may have a beneficial role in patients treated for COVID19 pneumonia, in terms of shorter time to clinical improvement, less need for MV, shorter hospital stay, and possibly lower mortality. HdM was well tolerated. This is the first report describing the benefits of hdM in patients being treated for COVID19 pneumonia.  Being a commonly available and inexpensive sleep-aid supplement worldwide, melatonin may play a role as adjuvant therapy in the global war against COVID19.

The use of radiation therapy for treatment of breast cancer has steadily increased since the 1990s. Plastic surgeons must be prepared to reconstruct patients with prior lumpectomy and radiation now needing salvage mastectomy, as well as the growing number of patients who will go on to need post mastectomy radiation therapy. Operating in the irradiated field presents unique challenges, including but not limited to intra-operative difficulties such as friable vessels when performing autologous-based reconstruction and higher rates of post-operative complications when performing implant-based reconstruction. Reconstructed outcomes are often inferior to the non-irradiated patient and as such the plastic surgeon should be prepared to perform further revision as necessary. This chapter will review indications for radiation therapy, both autologous- and implant-based approaches to reconstructing the irradiated breast and how to manage post-operative complications. This review contains 3 figures, 5 tables, and 75 references.

Objectives: The purpose of this study was to assess the safety of sacrohystcopxy by determining intraoperative and post-operative complications and its effectiveness by pelvic organ prolapse recurrence on follow up. Study Design: Prospective study. Setting: Department of Gynecology and Obstetrics Unit-II DHQ Hospital PMC, Faisalabad. Period: Jan-2014 to Jan-2017. Material & Methods: Patients with uterovaginal prolapse, admitted through OPD were selected for abdominal sacrohysteropexy. Variables of study including duration of surgery, any intra-operative and post operative complications, need of intra operative blood transfusion, post operative hospital stay; recurrence of POP, number of pregnancies in 06 moths follow up were recorded. Results: During this study period, 319 patients were admitted with uterovaginal prolapse. 32 (10.03%) cases were selected for abdominal sacrohysteropexy. In these 32 patients, 03 (9.37%) were <30years of age, 21(65.62%) were between 30-35 years and 8 (25%) were between 35-40 years of age. About 2(6.25%) were unmarried, while 30(93.7%) were married. In these married women 14(43.75%) were multiparas, another 14(43.75%) were para 1 or 2, while 4(12.5%) were para 3 or more. Duration of surgery was 40-45 minutes in 31(96.87%) patients. In 28(87.5%) cases per operative blood loss was <150ml while in 4(12.5%) it was estimated to be >150ml but less than 300ml. Post operatively only 1(3.12%) case developed wound sepsis and it was the only one (3.12%) who was discharged on 7th post operative day, while rest 31(96.87%) were discharged on 3rd post operative day. No recurrence was noticed in 06 moths follow up, while 2(6.25%) patients became pregnant. Conclusion: Abdominal sacrohysteropexy is a safe and an effective treatment in terms of overall anatomical and functional outcome, complications, post operative recovery, length of hospital stay and sexual functioning, in women who desire uterine and hence fertility preservation.

Penetrating Abdominal Trauma

Introduction: The incidence of penetrating abdominal injuries has been on the rise. The common availability of rearms, the lack of proper law, armed conicts, civil violence and road trafc accidents are the major causes of penetrating abdominal injuries. As patient with penetrating abdominal trauma are at risk of harbouring life threatening injuries, early diagnosis and timely intervention is the most important steps to reduce its morbidity as well as mortality. Recently due to improvement of the present healthcare system, the outcome of these injuries is improving. Materials And Methods: A descriptive observational study was carried out on 60 cases of penetrating abdominal injuries. A predesigned pretested schedule was used for data collection. Interview of the study subject and evaluation of all clinical reports was done to obtain the history, clinical ndings, management, complications, mortality and follow up. Before data collection, informed consent was obtained from each and every study subjects. Results: The overall incidence of penetrating abdominal trauma was found to be 2.30% of the total admission of 6217 patients in the department of surgery. The most common cause of penetrating abdominal injury found in this study is stab injury by sharp objects which is followed by gunshot injury. The commonest age group affected was 20 to 30 years which comprises about 41.67%. In this study we found a male preponderance in cases of penetrating injury to the abdomen. In most of the cases the mode is homicidal stab or gunshot injury followed by accidental injuries. Pain, abdominal distension and bleeding from the wound are the main presenting symptom. After initial evaluation with USG (FAST),CTscan abdomen is the most valuable investigation so far. In this series, it is found that the small intestine is the most commonly involved viscera followed by colon, omentum, mesentery and liver respectively. Most common complications after operative intervention was wound infection. The average hospital stay was 6 to 15 days. It has been observed that the post-operative complications, associated injuries and multiple organ injuries are the cause of increased hospital stay. Conclusion: Penetrating trauma can be serious because it can damage internal organs and presents a risk of shock and infection. In the present year, due to overall improvement in the communication and transportation, better monitoring systems and resuscitative measures, improvised diagnostic methods, better availability of blood and blood products, better medications and more skilful surgical techniques, the outcomes of these injuries are improving.

Objective: To evaluate the consequent outcomes in the patients with rectal cancer endured laparoscopic surgical excision at Department of Surgery, Liaquat University of Medical and Health Sciences Jamshoro, Hyderabad and to review their curative resection and recurrence rates, postoperative morbidities and complete survival. Methods: This prospective case series study was done at the Department of General Surgery of Liaquat University of Medical & Health Sciences, Jamshoro, Sindh, Pakistan. All patients of 30-65 years ages with rectal cancer and underwent diagnostic laparoscopy either of gender were included. After removing the tumor, the specimen pinned out on a flat surface and placed in fixative solution to allow the orientation of the specimen and assessments of the exact margins. As the specimens had acceptable clear margins and limited invasion to the submucosa, no further surgical procedure was proceeded. Data was collected via study proforma. Results: A total of 40 patients were studied. Patients in the laparoscopic operation lost less blood with an amount of only 200mL during 190 minutes average operation time. The bowel functioning returned in 2 days averagely with 8 days average hospital stay. Conclusion: It is concluded that laparoscopic surgery for rectal cancer is an effective, safe and feasible approach in terms of less post-operative complications and recovery time as well as Hospital stay. Key words: Rectal Cancer, laparoscopic surgery

Background: Non Descent Vaginal Hysterectomy (NDVH) is removal of uterus through vagina in non-prolapsed uterus. The objective of the present study was to assess safety and feasibility of NDVH in patients with large uterus (>12 weeks size uterus).Methods: Retrospective study was conducted in Department of Obstetrics and Gynecology of Shree Dharmasthala Manjunatheshwara (SDM) College of Medical Sciences and Hospital, Dharwad, India from May2014 to May 2017. Effort was made to perform hysterectomies vaginally in women with benign conditions with large uterine size. Information regarding age, parity, uterine size, blood loss, duration of operation, number of fibroids, other surgical difficulties encountered, intra–operative and post-operative complications were recorded.Results: Total of 65 cases was selected for NDVH with large uterine size. All successfully underwent NDVH. 25 patients had uterus of 10-12 weeks size, 17 had uterine size of 12-14 weeks size. Mean duration of surgery was 90 min. Mean blood loss was 300ml. Post-operative complications were minimal. All patients had early mobility with faster resumption to daily activities. Mean hospital stay was 4-5 days.Conclusions: Non descent vaginal hysterectomy is safe, cost effective method of hysterectomy in women with large uterus requiring hysterectomy for benign conditions with less complications, shorter hospital stay and less morbidity.

Background: Hysterectomy is a common surgery performed by gynecologist worldwide. It can be done either by vaginal, abdominal or laparoscopic route. Non decent vaginal hysterectomy (NDVH) is less invasive, less time consuming and scar less surgery. The blood loss during surgery, intra-operative and post-operative complications are less in NDVH compare to TAH (total abdominal hysterectomy). Aim and objective: to compare the clinical outcome between NDVH and TAH. Method: A hospital based prospective study was done at Nepalgunj medical collage Kolhapur between March 2018–March 2019, 60 cases fulfilling selection criteria were selected, 30 cases underwent NDVH next 30 cases underwent TAH. Outcome is measured on the basis of operating time, blood loss during surgery, hospital stay and post-operative complications. Result: The most common indication for hysterectomy was fibroid uterus in both the groups (NDVH and TAH). The operating time, blood loss, hospital stay and post-operative complications were less in NDVH as compare to TAH. Conclusion: NDVH is a choice of surgery over TAH for freely mobile uterus with benign pathology and uterus size less than twelve weeks and without adenexal pathology.

Background: Ankle fractures in patients with complicated diabetes have significantly increased the rates of complications and poorer functional outcomes when treated nonoperatively, and there have been only modest reductions when treated operatively. We hypothesized that the minimally invasive, robust construct that tibiotalocalcaneal fixation with an intramedullary nail offers would result in high rates of limb salvage, acceptable rates of complications, and less loss of function, in this difficult patient population. Methods: This was an institutional review board–approved retrospective study of 27 patients with complicated diabetes who underwent tibiotalocalcaneal nailing of their ankle fracture as a primary treatment without formal joint preparation. Patients with complicated diabetes were defined as having neuropathy, nephropathy, and/or peripheral vascular disease. The mean clinical follow-up was 888 days. Patients were screened for associated risk factors. Data were collected on surgical complications. The outcomes measured included length of hospital stay, loss of ambulatory level, amputation, and time to death. The mean age was 66 years with an average body mass index of 38 and hemoglobin A1c of 7.4. Six fractures were open. Results: The limb salvage rate was 96%. The average hospital stay was 6 days, and the mean time to weightbearing was 6.7 weeks. The fracture union rate was 88%. The surgical complication rate was 18.5%, with no instances of malunions, symptomatic nonunions, or Charcot arthropathy. Eight patients died by final follow-up (mean, 1048 days). An ambulatory level was maintained in 81% of the patients. Conclusion: With high limb salvage rates, relatively early weightbearing, maintained ambulatory level, and acceptable complication rates, we believe our technique can be considered an appropriate approach to increase the overall survivability of threatened limbs and lives in this patient population. Level of Evidence: Level IV, retrospective case series.
